Description

Technical Field

[0001] The present application relates to the field of freight ropeways, and particularly to an automatic tension balancing support seat for an overhead belt freight ropeway, a support device for an overhead belt freight ropeway, and an automatic tension balancing method for an overhead belt freight ropeway. Background Art

[0002] For a belt freight overhead ropeway, where the freight belt runs on the overhead ropeway, it is still a new thing in China. The steel rope is fixedly connected to the top of the support. This freight ropeway has a high transportation volume, but the stress is worse than that of an ordinary freight ropeway.

[0003] In the existing structure, the existing freight ropeway supports and support seats are fixed to the ground. Under this structure, due to the large change in the line load of the belt freight overhead ropeway, the support seat and the support cannot balance the tensions of the steel ropes on both sides of the support. The tension of one side of the steel rope is easily exceeded, which is likely to damage the steel rope. The tipping moment of the support is also very large. To ensure safety, only the steel rope and the support need to be strengthened, and then the entire equipment must be strengthened, resulting in extremely high costs and being unfavorable for the promotion of this large-capacity belt freight ropeway. Summary of the Invention

[0004] In view of the above defects, in the first aspect, the present application provides an automatic tension balancing support seat for an overhead belt freight ropeway, which reduces the requirements for the steel rope and the support, thereby reducing the cost.

[0005] The technical solution is: an automatic tension balancing support seat for an overhead belt freight ropeway, which is a single set of support seat. The single set of support seat includes a support shaft, a rotatable sleeve, a left base, and a right base. The support shaft passes through the rotatable sleeve. One end of the support shaft is connected to the left base, and the other end is connected to the right base. The rotatable sleeve is located between the left base and the right base, and a connecting column is connected to the rotatable sleeve.

[0006] When the ropeway is in operation, the change in the line load will cause the deflection and length of the steel ropes fixed on both sides of the support to change. The automatic tension balancing support of the overhead belt freight ropeway forms a self-balancing hinge point with the support and the ropeway steel rope, reducing or avoiding the longitudinal (steel rope direction) bending moment of the support. When the force changes, the support can swing back and forth automatically to relieve the force, increasing the safety of the line.

[0029] Embodiment 1

[0030] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the automatic balance support seat for the tension of the overhead belt freight cableway in this embodiment.

[0031] An automatic balance support for the tension of an overhead belt freight cableway. The automatic balance support seat for the overhead belt freight cableway is a single set of support seats 100. The single set of support seats 100 includes a support shaft 101, a rotatable sleeve 102, a left base 105, and a right base 104. The support shaft 101 passes through the rotatable sleeve 102. One end of the support shaft 101 is connected to the left base 105, and the other end is connected to the right base 104. The rotatable sleeve 102 is located between the left base 105 and the right base 104, and a connecting column 103 is connected to the rotatable sleeve 102.

[0032] Please refer to Figure 2 , Figure 2 which is a schematic diagram of the working principle of this embodiment.

[0033] Figure 2 In , the bracket 200 is used to support the left cableway steel rope 301 and the right cableway steel rope 302, and the connecting column 103 of a single set of support seats 100 is connected to the bracket 200.

[0034] When the cableway is running, the change of the line load will cause the deflection and length of the steel ropes fixed on both sides of the bracket 200 to change. The automatic tension balance support 100, bracket 200, left cableway steel rope 301 and right cableway steel rope 302 of the overhead belt freight cableway form a self-balancing hinge point, reducing or avoiding the longitudinal (steel rope direction) bending moment of the bracket. When the force changes, the bracket 200 can swing back and forth to automatically relieve the force, increasing the line safety.

[0035] Optionally, in one or more specific embodiments, a single set of support seats 100 further includes a bottom plate 106, and the left base 105 and the right base 104 are respectively installed on the bottom plate 106. Installing the left base 105 and the right base 104 on the same bottom plate 106 eliminates the need for separate leveling and reduces the installation difficulty.

[0036] Optionally, in one or more specific embodiments, a single set of support seats 100 further includes two bearing bushes 107, and the two bearing bushes 107 are installed at both ends of the support shaft 101.

[0037] Optionally, in one or more specific embodiments, the bearing bush 107 is a double bearing bush, and the double bearing bushes are arranged on both sides with strong load-bearing capacity.

[0038] Optionally, in one or more specific embodiments, a bearing bush sleeve 108 is sleeved on the bearing bush 107. The bearing bush 107 is installed in the bearing bush sleeve 108 and can be disassembled separately, which is convenient for installation and disassembly and easy for maintenance.

[0039] Optionally, in one or more specific embodiments, a single set of support seats 100 further includes two baffles 109, and the two baffles 109 are respectively installed at both ends of the support shaft 101 and are located outside the bearing bush 107.

[0040] Optionally, in one or more specific embodiments, a single set of support seats 100 further includes two lateral slip rings 110, and the two lateral slip rings 110 are installed on the support shaft 101 and are respectively located between the rotatable sleeve 102 and the left base 105 and the right base 104. Installing the lateral slip rings 110 facilitates replacement after lateral wear.

[0041] Optionally, in one or more specific embodiments, a flange 111 is connected to the end of the connecting column 103, and is connected to the bracket 200 through the flange 111.

[0042] In this embodiment, the tower head of the support 200 bears the cable pressure, and then the support transfers the acting force F to the automatic tension balancing support 100 of the overhead belt freight ropeway. The acting force F borne by the automatic tension balancing support 100 of the overhead belt freight ropeway can be decomposed into a horizontal force Fp and a vertical force Fv. The horizontal force Fp acts on the transverse sliding ring 110. Since the support is stressed and will swing back and forth, the transverse sliding ring 110 is subjected to pressure and friction. The vertical force Fv acts on the two side bearing bushes 107. Since the support 200 is stressed and will swing back and forth, the two side bearing bushes 107 are subjected to pressure and friction. The transverse sliding ring 110 and the two side bearing bushes 107 can be lubricated, so the automatic tension balancing support 100 of the overhead belt freight ropeway can rotate flexibly to meet the swinging function of the support 200. When replacing the two side bearing bushes 107, remove the outer baffle 109 and pull out the bearing bush sleeve 108 to replace the bearing bush 107. After installing the new bearing bush 107 into the bearing bush sleeve 108, push the bearing bush sleeve 108 in and then install the baffle 109. When replacing the transverse sliding ring 110, remove the outer baffle 109 and pull out the base to replace it.
