Figure 2 This is a schematic top view of the portion of the steel wire rope pitch change device for the overhead belt ropeway installed in the ropeway station. Figure 3 This is a schematic diagram of the overall structure of the rope clamp unit of this application.

[0030] A pitch-varying device for a steel wire rope system of an overhead belt ropeway includes a horizontal pitch-varying structure, which includes two symmetrically arranged inner guide rope clamps 6 and two outer guide rope clamps 7. The two inner guide rope clamps 6 and the two outer guide rope clamps 7 are each provided with a rope groove 12. The rope grooves 12 of the two inner guide rope clamps 6 are horizontally inward, and the rope grooves 12 of the two outer guide rope clamps 7 are horizontally outward. The distance A between the rope grooves 12 of the two inner guide rope clamps 6 is smaller than the distance B between the rope grooves 12 of the two outer guide rope clamps 7.

[0031] The distance A between the rope grooves 12 of the two inner guide rope clamps 6 is smaller than the distance B between the rope grooves 12 of the two outer guide rope clamps 7, so that the distance between the two steel ropes changes from A to B after passing from the two inner guide rope clamps 6 to the two outer guide rope clamps 7, or the distance between the two steel ropes changes from B to A after passing from the two outer guide rope clamps 7 to the two inner guide rope clamps 6, thereby achieving variable distance.

[0032] Optionally, in one or more specific embodiments, the overhead belt ropeway wire rope pitch changing device also includes an up and down direction pitch changing structure, which includes two symmetrically arranged upper guide rope clamps 4 and two lower guide rope clamps 5, and the two upper guide rope clamps 4 and the two lower guide rope clamps 5 are each provided with a rope groove 12, the rope grooves of the two upper guide rope clamps 4 are in the same horizontal plane, the rope grooves of the two lower guide rope clamps 5 are in the same horizontal plane, and the height difference C between the rope grooves of the two upper guide rope clamps 4 and the rope grooves of the two lower guide rope clamps 5 is greater than 0.

[0033] The height difference C between the rope grooves of the two upper guide rope clamps 4 and the rope grooves of the two lower guide rope clamps 5 is greater than 0, so that each steel rope descends after passing from the two upper guide rope clamps 4 to the two lower guide rope clamps 5, or rises from the two lower guide rope clamps 5 to the two upper guide rope clamps 4.

[0034] Optionally, in one or more specific embodiments, the overhead belt ropeway wire rope pitch change device also includes a second suspension frame 9 and a first suspension frame 10, the vertical pitch change structure is installed on the second suspension frame 9, and the horizontal pitch change structure is installed on the first suspension frame 10.

[0035] Optionally, the second suspension bracket 9 and the first suspension bracket 10 are made of steel sections, which reduces the mass of the entire device and is more suitable for aerial hanging.

[0036] Based on the above-mentioned overhead belt ropeway wire rope pitch changing device, the present application also provides an overhead belt ropeway.

[0037] An overhead belt ropeway includes a portion inside a ropeway station, which includes a top-level load-bearing steel wire rope 1, an intermediate track steel wire rope 2, a lower track steel wire rope 3, a conveyor belt, and a conveyor belt runner 11 running on the intermediate track steel wire rope 2 and the lower track steel wire rope 3. A set of the above-mentioned overhead belt ropeway steel rope rope rope variation device is respectively installed on the intermediate track steel wire rope 2 and the lower track steel wire rope 3, wherein a set of second suspension brackets 9 and first suspension brackets 10 are installed on the intermediate track steel wire rope 2, and another set of second suspension brackets 9 and first suspension brackets 10 are installed on the lower track steel wire rope 3.

[0038] Optionally, in one or more specific embodiments, the cableway station interior further includes four transition rail switches 8, one end of the transition rail switch 8 is pressed on the lower rail wire rope 3 or the middle rail wire rope 2 in the rope groove of an upper guide rope clamp 4.

[0039] The arrangement of the four transition rail switches 8 allows the conveyor belt running wheel 11 to smoothly transition to the transition rail switch 8 when the pitch is changed in the up and down directions, thereby avoiding the conveyor belt running wheel 11 being suspended in the air after the up and down pitch change, which would cause a greater impact on the hard rail in the upper station.

[0040] Optionally, the rope groove 12 is an arc outer edge that matches the groove of the conveyor belt running wheel 11, which fits with the conveyor belt running wheel 11 to make the running wheel transition smoothly, avoiding the risk of lifting the conveyor belt running wheel 11 when the conveyor belt running wheel 11 passes, causing large vibration and impact, and causing the conveyor belt running wheel 11 to jump out of the rope groove and derail.

[0041] The present application solves the problem of pitch change of the steel wire rope of the overhead belt ropeway track in the station, and solves the interference between the conveyor belt running wheel 11 and the steel wire rope of the track during the return operation in the station. It can realize pitch change in two directions of the steel wire rope, and the pitch change is smooth, so that the inertial impact and noise of the conveyor belt running wheel when transitioning from the steel wire rope system to the hard rail in the station are small, which effectively extends the service life of the running wheel and reduces the replacement cost of the running wheel wearing parts.

[0042] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
