Abstract

A traction rope adjustment apparatus includes a traction rope pressing device, and a traction rope pulley apparatus. The traction rope lifting apparatus prevents the traction rope sagging, the traction rope pressing apparatus prevents the traction rope drifting, and the traction rope pulley apparatus enables a car and the counterweight to smoothly pass through the traction rope pressing apparatus, thereby implementing forced guidance of the traction rope and the reliable and smooth running of the car and counterweight. The apparatus can meet the demands of variable gradients and can implement reliable running of an inclined running container in variable gradients, such that the traction rope adapts to the different gradients, solving the challenge of the development of an inclined running container that self-adapts to gradients.

First claim

The invention claimed is:

1. A variable gradient inclined running container traction rope adjustment apparatus, comprising upper and lower guide rails, a counterweight apparatus, a traction rope, a traction machine and a supporting seat supporting a car and riding on the upper guide rail, wherein
the traction machine is arranged on the top of the variable slope;
one end of the traction rope winding around the traction machine is connected with the supporting seat running on the upper guide rail, and the other end is connected with the counterweight apparatus running on the lower guide rail;
the bottoms of the traction rope connecting car and the counterweight apparatus are respectively provided with a traction rope pulley apparatus;
a traction rope lifting apparatus is arranged on a support frame of the upper and lower guide rails, positioned at the lower section of the slope, and a traction rope pressing apparatus is arranged on the support frame positioned at the upper section of the slope;
a traction rope guide pulley is arranged below the traction machine; and,
a movable connecting plate is arranged at the bottom of the car, one side of the front end of the upstream between the movable connecting plate and the supporting seat is hinged, and automatic leveling assembly is connected to one side of the rear end of the upstream.

2. The variable gradient inclined running container traction rope adjustment apparatus according to the claim 1 , wherein the supporting seat comprises a lifting platform, a support frame arranged on the upper part of the lifting platform, and a car guide shoe arranged at the bottom of the lifting platform.

3. The variable gradient inclined running container traction rope adjustment apparatus according to the claim 1 , wherein
the traction rope lifting apparatus comprises a bearing member, angle cleats arranged at two ends of the bearing member, and a connecting shaft connecting the bearing member and the angle cleats.

4. The variable gradient inclined running container traction rope adjustment apparatus according to the claim 1 , wherein
the traction rope pressing apparatus comprises two connecting plates with the same structure, which are symmetrically fixed on the guide rail frame, three vertical plates with the same structure are arranged on the upper part of the connecting plate equidistantly in parallel;
a rotary wheel is arranged on the upper part of each vertical plate;
an upper wheel is arranged on the upper part of the rotary wheel;
rotary pins and positioning pins are respectively fixedly connected among the three vertical plates in parallel;
a rotary block rotating around the rotary pin is arranged on the rotary pin;
a connecting pin is arranged at the end of the rotary block;
a central shaft passing through the rotary wheel and connected with the upper wheel is welded on the upper part of the rotary block;
a bearing matched with the central shaft is arranged in the rotary wheel;
one end of the bearing is positioned via a shaft shoulder of the central shaft, and the other end is positioned via a shaft sleeve;
one end of the rotary wheel is limited via the bearing, and the other end is limited via a retainer ring;
a spring is arranged between the positioning pin and the connecting pin; and,
one end of the spring is fixed to the positioning pin, and the other end of the spring is fixed to the connecting pin.

5. The variable gradient inclined running container traction rope adjustment apparatus according to the claim 1 , wherein the counterweight apparatus comprises a front counterweight and a rear counterweight, the front and rear counterweights are hinged together, and counterweight guide shoes are arranged at the bottom of the front and rear counterweights symmetrically.

6. The variable gradient inclined running container traction rope adjustment apparatus according to the claim 1 , wherein the traction rope pulley apparatus comprises a rope threading pulley, side plates distributed on both sides of the rope threading pulley, and a bolt connecting the rope threading pulley and the side plates.

7. A variable gradient inclined running container traction rope adjustment method using the apparatus in the claim 1 , wherein
when the inclined running container runs, a bearing member of the traction rope lifting apparatus will lift the traction rope up, and rotary wheels of the traction rope pressing apparatus will compress the traction rope, thereby achieving the forced guidance of the traction rope;
when the car or the counterweight apparatus passes through the traction rope pressing apparatus, side plates of the traction rope pulley apparatus arranged at the bottom of the supporting seat and the counterweight apparatus will push aside an upper wheel towards left and right sides, so that the car and the counterweight apparatus can smoothly pass through the traction rope pressing apparatus; and
after the car or the counterweight apparatus passes through the traction rope pressing apparatus, the upper wheel will return under the action of a spring, and the traction rope will be pressed between the rotary wheels again.
