Description

Technical Field

[0001] This utility model relates to the field of cableway equipment technology, and in particular to a tooling for changing the pressure sheave of a passenger cableway. Background Technology

[0002] Passenger ropeways refer to "ropeways" used to transport passengers. There are two types: reciprocating ropeways and circulating ropeways. The former has a passenger car hanging on each of the support cables on both sides of the line support, and is pulled back and forth along the line by one or two traction cables. The latter has several passenger cars or chairlifts hanging at equal intervals on the steel wire ropes on both sides of the line support, and is driven by a drive motor to circulate the steel wire ropes.

[0003] In existing technology, in order to replace the cable sheave, the wire rope on the cable sheave needs to be stretched first. Usually, tools such as chain hoists are used to fix the wire rope, then stretch it away from the cable sheave, then disassemble the cable sheave, and then re-engage and lock it. This operation is very time-consuming and laborious, and it is also easy to damage the wire rope. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art. In the prior art, in order to replace the cable sheave, it is necessary to first stretch the wire rope on the cable sheave. Usually, tools such as chain hoists are used to fix the wire rope, then stretch it away from the cable sheave, then disassemble the cable sheave, and then re-lock it. The operation is very time-consuming and laborious, and it is easy to damage the wire rope. The present invention proposes a tooling for replacing the cable sheave of a passenger cableway.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tooling for changing the pressure sheave of a passenger ropeway includes a housing and U-shaped rods, with two U-shaped rods slidably connected to both ends of the housing;

[0007] The housing is provided with an adjustment mechanism, which includes a rotating rod, a first gear, a first rack plate, and a clamping plate. The rotating rod is rotatably connected to the inner side wall of the housing. The first gear is fixedly connected to the outer surface of the rotating rod. The two first rack plates are respectively fixedly connected to one end of the U-shaped rod. The first rack plates are meshed with the first gear. The clamping plate is fixedly connected to the end of the U-shaped rod away from the first rack plates.

[0008] Preferably, a limiting sleeve is fixedly connected to the inner wall of the housing, and a slider is slidably connected to the inner wall of the limiting sleeve.

[0009] Preferably, an electric push rod is fixedly connected to the upper end face of the housing, a pentagonal block is fixedly connected to the telescopic end of the electric push rod, a trapezoidal block is fixedly connected to the side wall of the slider, and the trapezoidal block is slidably connected to the pentagonal block.

[0010] Preferably, a second gear is fixedly connected to the outer surface of the rotating rod, and a second rack plate is fixedly connected to the upper end face of the slider, with the second gear meshing with the second rack plate.

[0011] Preferably, a Z-shaped rod is fixedly connected to the lower end face of the pentagonal block, and a U-shaped block is fixedly connected to the lower end face of the Z-shaped rod.

[0012] Preferably, a return spring is fixedly connected between the slider and the housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By using a combination of clamping plates, pentagonal blocks, trapezoidal blocks, and other structures, an electric push rod is used to move the pentagonal blocks downwards to squeeze the trapezoidal blocks, which in turn causes the two clamping plates to quickly fix the shell onto the steel beam. Then, the Z-shaped rod is used to pull the U-shaped block to tighten the wire rope and move it away from the cable sheave. Compared with using tools such as chain hoists to fix the wire rope, this method is simpler, faster, and saves time and effort, greatly improving the efficiency of replacing and disassembling the cable sheave without damaging it.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0022] Reference Figures 1-4 A tooling for changing the pressure sheave of a passenger cableway includes a housing 1 and U-shaped rods 2. The housing 1 is internally sealed to prevent damage to internal components such as the first gear 4 from external dust and to facilitate lubrication. Two U-shaped rods 2 are slidably connected to the two ends of the housing 1. The U-shaped rods 2 are not circular and can only slide without rotating inside the housing 1, making the transmission of the first rack plate 5 more stable. An adjustment mechanism is provided inside the housing 1, which includes a rotating rod 3, the first gear 4, the first rack plate 5, and a clamping plate 6. The rotating rod 3 is rotatably connected to the housing 1. On the inner wall, the first gear 4 is fixedly connected to the outer surface of the rotating rod 3, and the two first rack plates 5 are respectively fixedly connected to one end of the U-shaped rod 2. The first rack plates 5 are meshed with the first gear 4. The clamping plate 6 is fixedly connected to the end of the U-shaped rod 2 away from the first rack plates 5. The clamping plate 6 is L-shaped. The inner wall of the clamping plate 6 is provided with oil-resistant and wear-resistant rubber such as nitrile rubber. Even with a certain amount of oil on the steel beam, it can maintain a fairly high coefficient of friction and can be firmly fixed. The clamping plate 6 is fixed by bolts and can be replaced according to the size of the cable pulley.

[0023] Reference Figure 4 A limiting sleeve 7 is fixedly connected to the inner wall of the housing 1. A slider 8 is slidably connected to the inner wall of the limiting sleeve 7. A return spring 16 is fixedly connected between the slider 8 and the housing 1. The limiting sleeve 7 is hollow inside and the outer shell has considerable strength. The limiting sleeve 7 limits and supports the slider 8 and provides a stable connection between the second rack plate 13 and the second gear 12.

[0024] Reference Figure 2 An electric push rod 9 is fixedly connected to the upper end face of the housing 1. A pentagonal block 10 is fixedly connected to the telescopic end of the electric push rod 9. A trapezoidal block 11 is fixedly connected to the side wall of the slider 8. The trapezoidal block 11 and the pentagonal block 10 are slidably connected.

[0025] Reference Figure 4The outer surface of the rotating rod 3 is fixedly connected to the second gear 12, and the upper end face of the slider 8 is fixedly connected to the second rack plate 13. The second gear 12 and the second rack plate 13 are meshed and connected. The diameter of the second gear 12 is smaller than that of the first gear 4. That is, the clamping plate 6 is fixed quickly first, and then the wire rope is gradually pulled after it is fixed. This avoids the reaction force of the wire rope on the shell 1 from affecting the fixation of the shell 1, causing deviation and other dangers, or wasting time by re-fixing.

[0026] Reference Figure 3 A Z-shaped rod 14 is fixedly connected to the lower end face of the pentagonal block 10. The Z-shaped rod 14 is slidably connected to the shell 1. The upper part of the Z-shaped rod 14 is on the side of the steel beam, the middle transverse part is lower than the clamping plate 6, and the lower part is located in the center of the steel beam, on the same plane as the wire rope, so that it will not interfere with the steel beam. A U-shaped block 15 is fixedly connected to the lower end face of the Z-shaped rod 14. The inner wall of the U-shaped block 15 is relatively wide and smooth, the contact pressure is small and will not damage the wire rope, and the length prevents the wire rope from detaching from the U-shaped block 15 and causing danger.

[0027] In this utility model, during use, simply place the housing 1 on the fixed steel beam near the cable pulley, then insert the U-shaped block 15 into the wire rope, keeping the distances between the two clamping plates 6 and the two sides of the fixed steel beam as equal as possible. Then, activate the electric push rod 9 to move the pentagonal block 10 downwards. The downward movement of the pentagonal block 10 compresses the trapezoidal block 11, causing the trapezoidal block 11 to move the slider 8 backwards into the limiting sleeve 7 and compress the return spring 16. The slider 8 moves the second rack plate 13, which in turn drives the rotating rod 3 to rotate via the second gear 12. The rotating rod 3 drives the first gear 4 to rotate, which in turn drives the two first rack plates 5 to rotate. The two first rack plates 5 move the two U-shaped rods 2 closer together, and the two U-shaped rods 2 clamp the steel beam with the two clamping plates 6, fixing the housing 1 to the steel beam. Since the diameter of the second gear 12 is smaller than that of the first gear... 4. Therefore, the pentagonal block 10 only moves down a small distance. At this time, the Z-shaped rod 14 and the U-shaped block 15 only move down a small distance, and the force on the wire rope is minimal. Therefore, the force on the shell 1 by the wire rope is also minimal. Therefore, the shell 1 is not easy to tilt during the hand-holding process. When the right-angled surface of the trapezoidal block 11 contacts the right-angled surface of the pentagonal block 10, the trapezoidal block 11 no longer moves backward, and the clamping force no longer changes. The two clamps 6 firmly fix the shell 1 on the steel beam. At this time, the pentagonal block 10 continues to move down, driving the Z-shaped rod 14 and the U-shaped block 15 to move down. The U-shaped block 15 moves down and stretches the wire rope downward and tightens it, so that it is separated from the cable pulley, which makes it convenient to replace and disassemble the cable pulley. The cable pulley and the pressure cable pulley only need to be reversed, which greatly improves the efficiency of disassembling and replacing the cable pulley. The large contact area between the U-shaped block 15 and the wire rope is also less likely to damage the wire rope.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
