[0002] Endless rope transmission is a type of wire rope transmission and is the most commonly used mode of transportation for mine auxiliary transportation. The most typical equipment is the endless rope winch, which uses the wire rope to work in a circular manner to realize the transportation function of underground working equipment. The endless rope winch has the advantages of easy installation, simple operation, low investment, low cost, long transportation distance and transportation continuity. In coal mine production, it occupies a large proportion as the main or auxiliary transportation equipment and plays a very important role. In long-distance transmission, the wire rope must be equipped with a support device to prevent it from falling under the influence of gravity. In the prior art, a clamping wheel is generally provided to support the wire rope. However, due to the harsh environment underground and many uncertain factors, debris can easily cause the clamping wheel to rotate inflexibly, which in turn causes the friction between the clamping wheel and the wire rope to change from rolling to sliding, accelerating the wear of the wire rope. In addition, there is also the phenomenon of the wire rope detaching from the clamping wheel, which seriously affects safety and production. Summary of the invention

[0011] Preferably, it also includes: a dust ring, which is vertically fixed at the through hole, and the movable blocking rod passes through the dust ring with a gap left between the two.

[0012] Preferably, the upper end of the movable lever is an inverted boss that contacts the upper surface of the dust ring; the outer contour of the cross section of the upper end of the movable lever and the inner contour of the cross section of the spring tube are both rectangles with arc-shaped ends.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In the embodiment, the cable grip 10 refers to a connecting device for connecting the machine body and the steel wire rope 9 in the aerial ropeway, which ensures that the machine body and the steel wire rope 9 are automatically connected and disconnected, and is sensitive and reliable to prevent the machine body from falling. The cable grip 10 is a prior art, and its structure is as follows Figure 1 and 2 shown.

[0027] like Figure 3 As shown, the support device for wire rope transmission of this embodiment includes: a support wheel seat 1 with a single-side opening and a spring seat assembly; at least one through hole is opened on the top of the support wheel seat 1, and the spring seat assembly is arranged one by one in correspondence with the through hole; the spring seat assembly includes: a hollow spring barrel 2 with one end sealed, a movable blocking rod 3, a compression spring 5 and a pulley 7; the lower end of the movable blocking rod 3 passes through the through hole, and a pulley 7 is rotatably arranged, and the pulley 7 stands upright on the lower bearing surface of the support wheel seat 1; the spring barrel 2 is vertically fixed on the support wheel seat 1, and the opening of the spring barrel 2 is located at the through hole; the compression spring 5 arranged in the spring barrel 2, and its two ends are respectively in contact with the top of the spring barrel 2 and the top of the movable blocking rod 3. In this embodiment, the matching clearance between the pulley 7 and the movable blocking rod 3 is small, which can effectively prevent small stone chips from entering and blocking the pulley 7 in harsh working conditions. When the rope gripper 10 passes through, the contact with the pulley 7 is rolling friction, and lifting the movable blocking rod 3 can effectively reduce the resistance.

[0028] Preferably, the first contact point between the cable grip 10 and the pulley 7 is lower than the center of the pulley 7, so that the cable grip 10 and the pulley 7 will not be stuck.

[0029] Preferably, two ends of the compression spring 5 are respectively fixedly connected to the top end of the spring tube 2 and the top end of the movable blocking rod 3 .

[0030] Preferably, the number of through holes and spring seat assemblies is two each, and the distance between the two spring seat assemblies is greater than the length of the cable gripper 10, so that the wire rope 9 is always locked in the support wheel seat 1 to avoid detachment from the support point. Figure 8 shown.

[0031] Preferably, the sealing end of the spring tube 2 is a dovetail cover and is sealed with glue.

[0032] Preferably, the supporting wheel seat 1 is C-shaped or U-shaped.

[0033] like Figure 4 As shown, the supporting device for wire rope transmission of the embodiment further includes: a semicircular arc Teflon bushing 8, which is fixed in the semicircular arc groove of the supporting wheel seat 1. The material of the Teflon bushing 8 is Teflon, which has the characteristics of high temperature resistance, and its friction coefficient is extremely low, and has a lubricating effect. It can effectively reduce the friction loss of the wire rope 9 during the traction process, increase the service life of the wire rope 9, and can be used in harsh working conditions.

[0034] Preferably, the spring tube 2 is in a boss shape, and the spring tube 2 is fixedly connected to the supporting wheel seat 1 by a plurality of bolts.

[0035] The supporting device for wire rope transmission in the embodiment further includes: a dust ring 6, which is vertically fixed at the through hole, and the movable blocking rod 3 passes through the dust ring 6, and a gap is left between the two. The dust ring 6 can prevent external dust from entering the spring tube 2, effectively protect the compression spring 5, increase its service life, and thus ensure the service life of the entire device.

[0036] Preferably, the upper end of the movable stopper 3 is an inverted boss, which contacts the upper surface of the dust ring 6. The dust ring 6 also serves to limit and support the movable stopper 3.

[0037] like Figure 5 and 6 As shown, preferably, the outer contour of the cross section of the upper end of the movable lever 3 and the inner contour of the cross section of the spring barrel 2 are both rectangular with arc-shaped ends. When the movable lever 3 moves up and down in the spring barrel 2, the movable lever 3 can be effectively prevented from rotating radially.

[0038] Preferably, if Figure 4 As shown, a through slot is vertically opened at the lower end of the movable blocking rod 3, the height of the through slot is smaller than the diameter of the pulley 7, and the pulley 7 is rotatably arranged in the through slot.

[0039] The working process of the supporting device for wire rope transmission in the above embodiment is as follows: Figure 7-9As shown, the mounting device is fixed to the steel wire rope 9 under the action of the cable gripper 10, and slides on the track through the supporting device under the traction of the steel wire rope 9. When the cable gripper 10 passes through the supporting device under the traction of the steel wire rope 9, it first passes through the first spring seat assembly, contacts the pulley 7 and lifts the movable blocking rod 3, so that the compression spring 5 is compressed; after the cable gripper 10 passes through the spring seat assembly, the pulley 7 and the movable blocking rod 3 are reset under the action of the compression spring 5, and the pulley 7 contacts the supporting wheel seat 1 to form a closed loop, locking the steel wire rope 9 in the semicircular Teflon bushing 8; after the first spring seat assembly is completely closed, the cable gripper 10 begins to contact the second spring seat assembly, and after the same action as the first spring seat assembly, it completely passes through the supporting device.

[0040] The supporting device for wire rope transmission in the above embodiment adopts the structure of double spring seat assembly, which can float and close successively when the rope gripper passes, and always keep one group in a closed state, effectively preventing the wire rope from being forced out; and the overall structure is compact and has the same axial direction as the wire rope, and can be installed in many situations where space is limited; it is easy to install, and the wire rope can be pressed in by only lifting the movable blocking rod 3 after fixing it, which is simple and effective, and greatly improves the work efficiency of installation.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
