Description

Technical Field

[0001] The utility model relates to the technical field of steel wire rope replacement, in particular to a mobile steel wire rope retracting and releasing device. Background Art

[0002] The main production equipment in the metallurgical industry, such as loopers and cranes, requires steel wire ropes. The length of the steel wire ropes used generally ranges from 200 to 1000 meters. As the use time increases, the steel wire ropes often break, wear, kink and other faults occur, requiring maintenance personnel to replace them in time. Since such equipment is often arranged at high altitude or underground, the equipment is compactly arranged and the working space is narrow, the installation of new steel wire ropes and the winding and recycling of old steel wire ropes are mostly replaced manually.

[0003] Usually, the replacement process of the new wire rope is to manually place the new wire rope drum on the vertical support, and use manual or original equipment drive winch to assist in pulling the wire rope for gradual replacement. During the operation, the new wire rope drum needs to be manually placed on the temporary support, and multiple people need to work together to rotate the wire rope drum to loosen the wire rope for a distance, and then the original winch will rotate in a jog manner to wind the wire rope for a distance, and repeat this process continuously to finally fix the new wire rope in place. During the replacement process, the wire rope and drum on the temporary support are very heavy, so it is very difficult for personnel to rotate the drum. At the same time, due to inertia and poor coordination of the loop winch in a jog manner, the drum rotates out of control, and the new steel wire becomes tangled and scattered; it puts a heavy burden on the operators and poses a risk to the safety of the operation; at the same time, the old rope is generally recycled for steelmaking, and the wire rope needs to be rolled on the drum or cut into a certain length, which can only be done manually, with high work intensity and long time consumption, which restricts the progress of maintenance.

[0035] Embodiment 1:

[0036] In a typical embodiment of the present invention, Figure 1 and Figure 2 As shown, a mobile wire rope retracting and releasing device is provided.

[0037] Since equipment equipped with wire ropes is often arranged at high altitudes or underground, the equipment is compactly arranged and the working space is narrow, the installation of new wire ropes and the winding and recovery of old wire ropes are mostly done manually, which generally requires 15-20 people and takes 6-10 hours to complete. During the operation, people are in direct contact with and pull on the wire ropes, posing a safety risk of injury.

[0038] Based on this, the present embodiment provides a mobile wire rope retracting and releasing device, which utilizes a mobile vehicle 7 with the function of winding and releasing the wire rope to be flexibly arranged near the equipment that needs to replace the wire rope, and the new wire rope and its drum are installed on the mobile vehicle 7. The drum is tightened and fixed by an inclined wedge structure, and the driving mechanism 5 is used to drive the forward and reverse rotation of the wire rope drum 1, which cooperates with the transmission winch of the original equipment to complete the release and installation of the new wire rope and the winding and recovery of the old wire rope. At the same time, the wire rope drum 1 is equipped with a stop lock during operation, which saves work time and improves safety.

[0039] The mobile wire rope retracting and releasing device is described in detail below with reference to the accompanying drawings.

[0040] like Figure 1 and Figure 2 As shown, the mobile wire rope retracting and releasing device includes a moving vehicle 7, a support 2, a stopping mechanism 3, a tensioning mechanism 4 and a driving mechanism 5. The support 2 and the driving mechanism 5 are both fixedly mounted on the upper side of the moving vehicle 7. The support 2 is used to support the expansion and contraction shaft 8 on which the wire rope drum 1 is mounted. In order to provide stable support, the supports 2 are arranged in pairs.

[0041] The expansion shaft 8 passes through one of the supports 2 and is sequentially connected to the stop mechanism 3 and the drive mechanism 5. The stop mechanism 3 is used to stop the wire rope drum 1 when the wire rope needs to be stopped during the intermission or when the personnel are working inside the retracting vehicle to prevent the drum from rotating suddenly. The tensioning mechanism 4 is arranged in the expansion shaft 8. The tensioning mechanism 4 is used to tighten the wire rope drum 1 after the wire rope drum 1 is hoisted in place; the drive mechanism 5 is used to drive the wire rope drum 1 to rotate.

[0042] Specifically, Figure 3 As shown, the mobile vehicle 7 includes a base 71 and wheels 72 installed on the bottom surface of the base 71. In order to facilitate movement, a hand lever is installed on the base 71, and the mobile vehicle 7 can be moved to different use sites by pulling the hand lever; the lever can be set on any side of the base 71 as long as it does not affect the retraction and release of the wire rope. When the mobile vehicle 7 moves to the desired position, in order to keep the mobile vehicle 7 stable and avoid tipping during the replacement of the wire rope, the base 71 is also connected to a leg 73, and the leg 73 is connected to the base 71 through a telescopic structure, so that the leg 73 can be folded up when not in use.

[0043] A guardrail 6 may also be installed on the upper side of the base 71 , and the guardrail 6 is symmetrically arranged on both sides of the support 2 to prevent the steel wire rope from being thrown out and injuring people, thereby increasing the safety of the device.

[0044] In this embodiment, the wheels 72 are made of rubber material, which can protect the ground from being scratched and further improve safety performance.

[0045] like Figure 4 As shown, the wire rope drum 1 is used for winding the wire rope, and the wire rope drum 1 can be set according to the size range of the tensioning mechanism 4.

[0046] In this embodiment, a pair of supports 2 is provided to correspond to one wire rope drum 1; of course, in other embodiments, if multiple wire rope drums 1 are required, multiple pairs of supports 2 are provided. Figure 1 As shown, the two supports 2 are arranged opposite to each other with a certain distance between them so as to install the expansion and contraction shaft 8. As shown in FIG5(a) and FIG5(b), the support 2 includes a support body 21, and a support sleeve 22 is rotatably installed on the top of the support body 21. The support sleeves 22 of the two supports 2 are coaxially arranged, and the expansion and contraction shaft 8 can pass through the support sleeve 22, so that the support sleeve 22 plays the role of supporting the expansion and contraction shaft 8 and the wire rope drum 1.

[0047] In this embodiment, the rotational connection between the support sleeve 22 and the support 2 is achieved through a bearing, such as a self-aligning roller bearing. A through hole is opened at the top of the support body 21, and the support sleeve 22 is installed in the through hole through the bearing. The expansion and contraction shaft 8 can be pulled out in advance and pushed in from one end of the expansion and contraction shaft 8 after the wire rope drum 1 is hoisted into place, and is supported and fixed by the bearings at both ends of the support 2.

[0048] The stop mechanism 3 is installed on the outside of one of the supports 2. When the wire rope needs to be stopped during the intermission or when the personnel are working inside the retracting vehicle, the wire rope drum 1 is stuck to prevent the wire rope drum 1 from suddenly rotating and causing danger. As shown in Figure 7 (a) and Figure 7 (b), the stop mechanism 3 includes a chuck 31, a telescopic card plate 32 and an operating assembly. The expansion shaft 8 passes through the support 2 and is connected to the chuck 31. The chuck 31 can rotate with the expansion shaft 8; the telescopic card plate 32 is located at the lower side of the chuck 31 and is connected to the operating assembly. Under the action of the operating assembly, the telescopic card plate 32 can be driven to move to lock or release the chuck 31, thereby achieving the purpose of stopping.

[0049] The telescopic card plate 32 is a component with linear motion characteristics. In this embodiment, the telescopic card plate 32 is slidably connected to the side of the support 2. For example, the telescopic card plate 32 adopts a sliding block and a guide rail, and can slide up and down relative to the support 2 under the drive of the operating component.

[0050] In order to achieve the purpose of stopping, gear teeth are evenly arranged around the chuck 31 , and the telescopic card plate 32 has a slot matched with the gear teeth on the side facing the chuck 31 . When the telescopic card plate 32 moves upward, the slot can clamp the gear teeth, thereby locking the chuck 31 .

[0051] The operating assembly can drive the telescopic card plate 32 to move up and down. In the present embodiment, the operating assembly includes an operating rod 33, a first spring 34 and a fixed seat 35. The fixed seat 35 is installed on the upper side of the mobile vehicle 7. One end of the first spring 34 is connected to the telescopic card plate 32, and the other end is connected to the fixed seat 35. The operating rod 33 is fixed to the telescopic card plate 32. Under the action of the first spring 34, the telescopic card plate 32 can be moved downward by pressing the operating rod, and can be moved upward and clamp the chuck 31 under the action of the elastic force.

[0052] like Figure 6(a)-Figure 6(c) As shown, the interior of the expansion and contraction shaft 8 is a hollow structure, and the tensioning mechanism 4 is installed in the expansion and contraction shaft 8; the tensioning mechanism 4 includes a pull rod, an inclined wedge 45, and a second spring 43, wherein the inclined wedges 45 are arranged in groups, and multiple groups of inclined wedges 45 are arranged at intervals along the axial direction of the expansion and contraction shaft 8, each group is provided with two inclined wedges 45, and the two inclined wedges 45 are connected by the second spring 43, and the second spring 43 is arranged radially along the expansion and contraction shaft 8.

[0053] There are pull rods on both sides of each group of inclined wedges 45. In the present embodiment, for the convenience of description, the pull rod extending out of the expansion and contraction shaft 8 is defined as the first pull rod 42, and the pull rod located inside the expansion and contraction shaft 8 is the second pull rod 44; the first pull rod 42 is used to push the first group of inclined wedges 45, and the second pull rod 44 is used to push other groups of inclined wedges 45 when the first group of inclined wedges 45 moves.

[0054] As shown in Fig. 6(c), one end of the first pull rod 42 extends from the end of the expansion shaft 8, and this end is the end of the expansion shaft 8 that is not connected to the stop mechanism 3; the outer side of the extended end of the first pull rod 42 has a thread, which cooperates with the locking nut 41 through the thread. Rotating the locking nut 41 can make the first pull rod 42 move in the expansion shaft 8, thereby realizing the movement of the inclined wedge 45. The pull rod is used to push the inclined wedge 45 to slide out from the through slot 81 on the expansion shaft 8, and the wire rope drum 1 is tightened after the wire rope drum 1 is hoisted in place. After the operation is completed, the inclined wedge 45 is retracted by the elastic force of the second spring 43, which is convenient for removing the wire rope drum 1.

[0055] The driving mechanism 5 is used to drive the wire rope drum 1 to rotate through the expansion and contraction shaft 8, and its specific structure can be selected according to actual needs. In this embodiment, the driving mechanism 5 includes a motor 51 and a reducer 52, and the motor 51 and the reducer 52 are both fixed on the support seat 53. The reducer 52 is connected to the expansion and contraction shaft 8 through a coupling, and the motor 51 drives the worm reducer 52 to drive the wire rope drum 1, and then the point wiring is used.

[0056] The working principle of this embodiment is:

[0057] Pull the mobile vehicle 7 to the required working position, pull the tensioning mechanism 4 out of the support 2, lift the wire rope drum 1 to the drum installation position of the mobile vehicle 7 by the overhead crane, push the tensioning mechanism 4 into the support 2, use the locking nut 41 to drive the first pull rod 42 to tighten the wire rope drum 1, use the pin to fix the tensioning mechanism 4 and the support 2, start the driving mechanism 5, and rotate the wire rope drum 1.

[0058] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
