Description

Technical Field

[0001] This utility model relates to the technical field of monorail installation tools, and in particular to an auxiliary installation device for monorail tracks. Background Technology

[0002] When installing monorail tracks in locations such as mines, workers typically need to manually move and lift the tracks. Due to the track's considerable weight, prolonged periods of strenuous physical labor can easily lead to fatigue, muscle injuries, or even accidents. Traditional manual installation methods are not only inefficient but also place a significant burden on workers' health and increase operational risks. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary installation device for a monorail track. By setting up a lifting device and then cooperating with a winch and pulley block, the monorail track can be lifted, improving work efficiency and reducing the impact of high-intensity work on workers' health.

[0004] To achieve the above objectives, this utility model provides an auxiliary installation device for a monorail track, including a car body base frame and a lifting device fixedly installed on the car body base frame; the lifting device includes a fixed frame, a sliding frame slidably installed on the fixed frame with upper and lower limits, a support frame slidably installed on the sliding frame with upper and lower limits, and a traction rope wound between the fixed frame, the sliding frame, and the support frame; the fixed frame is fixedly installed on the car body base frame and a winch is installed on it; a first fixed pulley is installed on the top of the fixed frame; a first movable pulley is installed on the bottom of the sliding frame and a second fixed pulley is fixedly installed on the top; a support shovel protruding from the support frame is fixedly installed on the support frame; the support shovel is used to support the monorail; the traction rope passes through the winch, the first fixed pulley, the first movable pulley, and the second fixed pulley in sequence and then connects to the support frame.

[0005] With the above structure, the monorail track can be lifted by the cooperation of the winch and pulley block. The cooperation of the winch and pulley block can reduce the lifting force, save more effort, and eliminate the need for manual lifting, thus not putting a great burden on the health of workers.

[0006] Preferably, a second movable pulley is installed on the support frame, and the traction rope passes through the second movable pulley and is fixedly connected to the top of the sliding frame. This structural optimization achieves a labor-saving effect.

[0007] Preferably, the winch is a manually operated self-locking winch. This structural optimization prevents the winch from tipping over, which could cause the monorail track to fall.

[0008] Preferably, a set of sliding rollers is fixedly installed on the sliding frame, and a sliding track is provided on the fixed frame for the sliding rollers to slide along. The sliding rollers are engaged in the sliding track and slide up and down along the sliding track. A set of bearing rollers is fixedly installed on the support frame, and a support track is provided on the sliding frame for the bearing rollers to slide along. The bearing rollers are engaged in the support track and slide up and down along the support track. Through this structural optimization, sliding friction can be changed to rolling friction, reducing the difficulty of lifting and lowering.

[0009] Preferably, the sliding roller assembly is located in the lower middle part of the sliding frame, so that the sliding roller assembly will not disengage from the sliding track when the sliding frame slides to the top of the sliding track. This structural optimization maximizes the lifting height of the sliding frame and prevents the sliding roller assembly from derailing.

[0010] Preferably, four sets of sliding rollers are arranged symmetrically in pairs on the sliding frame; four sets of load-bearing rollers are also arranged symmetrically in pairs on the load-bearing frame. This structural optimization achieves force balance.

[0011] Preferably, the fixing frame includes two opposing columns and cross braces connecting the upper and lower ends of the columns; the two columns and cross braces form a rectangular frame structure; the sliding roller assembly includes a fixing plate and limiting wheels mounted side by side on the fixing plate, with the two limiting wheels located on both sides of the columns and clamping the columns between them; the columns are provided with inwardly recessed sliding tracks corresponding to the sliding trajectory positions of the limiting wheels. This structural optimization ensures the stability of lifting.

[0012] Preferably, the top of the sliding frame is provided with a downwardly extending limiting strip. When the support frame slides to the top of the sliding frame, the bottom of the limiting strip abuts against the support frame. This structural optimization prevents the support frame from sliding too far and causing it to collide with the pulley assembly above.

[0013] Preferably, there are two limiting strips, located on both sides of the sliding frame. This structural optimization achieves force balance.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] This utility model provides an auxiliary installation device for monorail tracks, which solves the technical problems of manual lifting during monorail track installation in the prior art, which is labor-intensive and prone to safety accidents. This utility model achieves the lifting of monorail tracks through the cooperation of winches and pulley blocks. The cooperation of winches and pulley blocks can reduce the lifting force, making it more labor-saving, and eliminating the need for manual lifting, thus not placing a great burden on the health of workers.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] The orientations mentioned in this specification are based on the orientation of the auxiliary installation device for the monorail track of this utility model when it is working normally. They do not limit the orientation during storage and transportation, and only represent relative positional relationships, not absolute positional relationships.

[0025] like Figures 1-6 As shown, an auxiliary installation device for a monorail includes a vehicle chassis 1 and a lifting device 2 fixedly mounted on the chassis 1. In use, the monorail is placed onto the lifting device 2, which then lifts the monorail to the top of the mine shaft for easy installation and hoisting. However, because monorails are relatively long, multiple devices are needed to lift a single track. Two or three devices can be used simultaneously, depending on the length of the monorail, to achieve the lifting effect.

[0026] The lifting device 2 includes a fixed frame 21, a sliding frame 22 that is slidably mounted on the fixed frame 21 with upper and lower limits, a support frame 23 that is slidably mounted on the sliding frame 22 with upper and lower limits, and a traction rope 24 that is wound between the fixed frame 21, the sliding frame 22 and the support frame 23.

[0027] The fixed frame 21 is fixedly installed on the chassis 1 of the vehicle body. It includes two opposing columns 211 and cross braces 212 connecting the upper and lower ends of the columns 211. The two columns 211 and the cross braces 212 form a square frame structure, and a winch 25 is installed on the fixed frame 21. A first fixed pulley 213 is installed on the top of the fixed frame 21. The sliding frame 22 is also a square frame structure, with the same structure as the fixed frame 21. A first movable pulley 221 is installed at the bottom, and a second fixed pulley 222 is fixedly installed at the top. A support shovel 231 protruding from the support frame 23 is fixedly installed on the support frame 23. The support shovel 231 is used to support the monorail.

[0028] The winch 25 can be either an electric winch or a manual winch. If an electric winch is used, a corresponding power supply and controller are required. In this embodiment, a manual self-locking winch is preferred. There are many existing technologies for manual self-locking winches, which will not be elaborated here.

[0029] The traction rope 24 passes through the winch 25, the first fixed pulley 213, the first movable pulley 221, and the second fixed pulley 222 in sequence before connecting to the support frame 23.

[0030] When the winch 25 is rotated, the traction rope 24 is wound around the winch 25. Then, under the action of the first fixed pulley 213, the first movable pulley 221, and the second fixed pulley 222, the carrying shovel 231 gradually rises, thereby lifting the monorail track. When the carrying frame 23 slides to the top of the sliding frame 22, it can no longer rise. The winch 25 continues to rotate, and the traction rope 24 lifts the sliding frame 22 and protrudes upward from the top of the fixed frame 21, thereby enabling the carrying shovel 231 to continue to rise.

[0031] With the installation of this device, the lifting of the monorail track is achieved through the cooperation of the winch 25 and the pulley block. The cooperation of the winch 25 and the pulley block can reduce the lifting force, making it more labor-saving, and it does not require manual lifting, thus not putting a great burden on the health of workers.

[0032] Furthermore, to further optimize the structure and make it more labor-saving, a second movable pulley 233 is installed on the support frame 23, and the traction rope 24 passes through the second movable pulley 233 and is fixedly connected to the top of the sliding frame 22. A hook 223 is provided at the bottom of the second fixed pulley 222 on the top of the sliding frame 22 for fixing the end of the traction rope 24.

[0033] To reduce the sliding resistance of the sliding frame 22 and the support frame 23, further improvements are made to the above structure. The sliding friction between the sliding frame 22 and the fixed frame 21, and between the support frame 23 and the sliding frame 22, is changed to rolling friction. To achieve this function, a set of sliding rollers 26 is fixedly installed on the sliding frame 22, and a set of support rollers 27 is fixedly installed on the support frame 23.

[0034] The fixed frame 21 is provided with a sliding track 214 for the sliding roller assembly 26 to slide. The sliding roller assembly 26 is engaged in the sliding track 214 and slides up and down along the sliding track 214. The sliding frame 22 is provided with a bearing track for the bearing roller assembly 27 to slide. The bearing roller assembly 27 is engaged in the bearing track and slides up and down along the bearing track.

[0035] In this embodiment, for stable support, four sets of sliding roller assemblies 26 are provided, symmetrically arranged in pairs on the sliding frame 22; four sets of bearing roller assemblies 27 are provided, symmetrically arranged in pairs on the bearing frame 23. To maximize the lifting height of the sliding frame 22 and prevent the sliding roller assemblies 26 from disengaging from the sliding track 214, the sliding roller assemblies 26 are located in the lower middle part of the sliding frame 22. When the sliding frame 22 slides to the top, the sliding roller assemblies 26 will still not disengage from the sliding track 214. To prevent the sliding roller assemblies 26 and the bearing roller assemblies 27 from derailing, baffles can be provided at the upper and lower ends of their corresponding tracks to limit their sliding area.

[0036] The sliding roller assembly 26 and the load-bearing roller assembly 27 have the same structure, differing only in their installation positions. The following description uses the sliding roller assembly 26 as an example.

[0037] The sliding roller assembly 26 includes a fixed plate 261 and two limiting wheels 262 mounted side-by-side on the fixed plate 261. The two limiting wheels 262 are located on both sides of the column 211 and clamp the column 211 between them. The column 211 has an inwardly recessed sliding track 214 corresponding to the sliding trajectory position of the limiting wheels 262. This structure improves the stability of the device.

[0038] To ensure the smooth upward sliding of the sliding frame 22, a downward-extending limiting strip 28 is provided at the top of the sliding frame 22. When the support frame 23 slides to the top of the sliding frame 22, the bottom of the limiting strip 28 abuts against the support frame 23. The relative position between the support frame 23 and the sliding frame 22 can no longer change. At this point, if traction continues, the sliding frame 22 will continue to slide upward, achieving a secondary lifting of the support frame 23. There are two limiting strips, located on both sides of the sliding frame 22.

[0039] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
