Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a building engineering lifting device. Background Technology

[0002] In the construction industry, a material hoist is a mechanical device used for vertical transportation of building materials and tools, typically used for material transport between floors on construction sites. It is primarily driven by a winch, combined with a cage or hopper, to quickly lift materials such as bricks, mortar, steel bars, and formwork to a designated height, thereby improving construction efficiency and reducing the labor intensity of manual handling.

[0003] Currently, some material hoist structures still have certain problems during use: Material hoists can transport materials from lower levels to higher balconies or floors, but because some balconies or floors have large areas and the unloading point of the material is far from the hoist, some material hoists are equipped with tracks. When the cage rises to a designated height, workers can quickly move the load in the cage to the designated unloading point via the tracks, and then return it to the cage. This structural design greatly improves the efficiency of workers' operations and makes them more relaxed and less strenuous. However, traditional track structures are not convenient for users to flexibly adjust the height, and the track length cannot be adjusted according to the unloading location, making the design less user-friendly.

[0004] Therefore, it is necessary to provide a new building construction lifting device to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a construction engineering lifting device that allows users to easily adjust the height of the track and adjust the length of the track according to the unloading point of the material.

[0006] To solve the above-mentioned technical problems, the present invention provides a building engineering lifting device comprising: a frame structure, wherein a lifting structure and a track assembly are installed on the surface of the frame structure, the frame structure includes a bracket, two brackets are provided and distributed left and right, and a limit member is provided at the rear side of each of the two brackets; the track assembly includes a slider, two sliders are provided and are slidably connected to the two limit members respectively.

[0007] The surface of the slider is fixedly connected to a movable track, and the surface of the movable track is provided with a positioning slot. Several docking tracks are provided on one side of the movable track. Each of the docking tracks is fixedly connected to a limit block at one end facing the movable track. A limit groove is provided at the end of the docking track away from the limit block. The limit grooves of two adjacent docking tracks are inserted into the limit blocks.

[0009] Through the above technical solution, the device is equipped with multiple interlocking docking tracks. Adjacent docking tracks are connected by limiting blocks and limiting slots, and then fixed by mounting bolts and mounting nuts. In this way, users can set up a sufficient number of docking tracks and splice them according to the material unloading points in the actual situation. The structural design is reasonable.

[0011] With the above technical solution, after the movable track is set to the height to dock with the platform, the bottom of one docking track may not be able to stably support the platform surface. Therefore, the device is specially designed with a movable part whose height can be finely adjusted for docking track.

A sliding member corresponding to the fixed rail is provided at the bottom of the carrier. The sliding member matches the fixed rail, the movable rail, and the docking rail.

[0013] With the above technical solution, in this device, the user can use the winch body to lift the cage, raise the carrier inside to a specified height and align the fixed rail with the movable rail on one side. Then the user can pull out the pin in the ear plate and pull the carrier, allowing the sliding part at the bottom of the carrier to slide along the docking rail on one side to the designated unloading point for unloading. The structural design allows the user to operate easily.

[0014] As a further embodiment of this utility model, a reinforcing member is fixedly connected to the bracket and the limiting member, and a diagonal support is fixedly connected to the surface of the bracket and the limiting member.

The base is slidably connected to the support and the limiting component. A height limiter is provided on one side of the winch body and is electrically connected to the winch body.

[0017] Through the above technical solution, the device is equipped with a height limiter for the winch body, which allows the user to trigger a deceleration or stop signal at a preset height point to assist in precise stopping, thereby allowing the fixed track to dock with the moving track.

[0018] As a further embodiment of this utility model, the surface of the limiting member is provided with several longitudinally distributed limiting holes, the surface of the slider is fitted with a locking bolt, the locking bolt passes through the limiting hole on one side and is threadedly connected with a limiting nut, the surfaces of the carrier and the base are both fixedly connected with ear plates, and a pin is inserted between the two ear plates.

[0019] Through the above technical solution, the height of the movable track in this device can be adjusted according to the height of the user's work platform. During adjustment, the slider is allowed to slide longitudinally along the limiting member to a suitable height. Then, the locking bolt on the surface of the slider passes through the limiting hole on the adjacent side and is locked with the limiting nut.

[0021] 1. In this utility model, the device is equipped with multiple segments of spliced ​​docking rails. Adjacent docking rails are connected by limiting blocks and limiting slots, and then fixed by mounting bolts and mounting nuts. In this way, the user can set up a sufficient number of docking rails and splice them according to the material unloading point in the actual situation. The structure is reasonably designed. In addition, the height of the movable rail in this device can be adjusted according to the height of the user's working platform. When adjusting, let the slider slide along the longitudinal direction of the limiting component to a suitable height, and then use the locking bolt on the surface of the slider to pass through the limiting hole on the adjacent side and lock it with the limiting nut. It is convenient and quick for the user to operate and the design is user-friendly.

[0022] 2. In this utility model, the user can use the winch body to lift the cage, raise the internal carrier to a specified height, and align the fixed rail with the movable rail on one side. Then, the user can remove the pin in the ear plate and pull the carrier, allowing the sliding part at the bottom of the carrier to slide along the docking rail on one side to the designated unloading point for unloading.

[0031] The frame structure 1 has a lifting structure 2 and a track assembly 3 installed on its surface. The frame structure 1 includes a support 10, which has two supports distributed on the left and right. Each of the two supports 10 has a limit member 11 at its rear side. The track assembly 3 includes a slider 16, which has two sliders and is slidably connected to the two limit members 11 respectively.

[0032] A movable track 14 is fixedly connected to the surface of the slider 16. A positioning slot 18 is provided on the surface of the movable track 14. Several docking tracks 15 are provided on one side of the movable track 14. A limit block 20 is fixedly connected to the end of each docking track 15 facing the movable track 14.

[0033] like Figure 1-4 As shown, mounting holes are provided on the surfaces of the positioning slot 18 and the limiting slot 19. Mounting bolts are inserted into the mounting holes, and the mounting bolts pass through the surface of the limiting block 20 and are threaded with mounting nuts.

[0034] The device is equipped with multiple interlocking docking rails 15. Adjacent docking rails 15 are connected by limiting blocks 20 and limiting grooves 19, and then fixed by mounting bolts and mounting nuts. In this way, users can set up a sufficient number of docking rails 15 and connect them according to the material unloading points in the actual situation. The structure is reasonably designed.

[0035] like Figure 1-4 As shown, a fixing member 23 is fixedly connected between two docking tracks 15 distributed on the left and right.

[0036] After the movable track 14 is set to the height to dock with the platform, the bottom of one docking track 15 may not be able to stably support the platform surface. Therefore, the device is specially designed with a movable part 24 whose height can be finely adjusted for docking track 15. When in use, rotate the threaded sleeve to extend the threaded rod 22 out of the outer cylinder 21 to a suitable length until the bottom of the movable part 24 is stably supported on the platform. The structural design is user-friendly.

[0037] like Figure 1-4 As shown, the lifting structure 2 includes a cage 25 and a winch body 7. The cage 25 includes a base 28 and a hanger. The hanger is fixedly connected to the base 28. Fixed rails 29 are fixedly connected to the left and right sides of the top surface of the base 28. A carrier 26 is provided on the upper side of the base 28. A sliding member 27 corresponding to the fixed rail 29 is provided at the bottom of the carrier 26. The sliding member 27 matches the fixed rail 29, the movable rail 14, and the docking rail 15.

[0038] In this device, the user can use the winch body 7 to lift the cage 25, raise the carrier 26 inside to a specified height and align the fixed rail 29 with the movable rail 14 on one side. Then, the user can pull out the pin in the ear plate and pull the carrier 26 so that the sliding part 27 at the bottom of the carrier 26 can slide along the docking rail 15 on one side to the specified unloading point for unloading. The structural design allows the user to operate it easily.

[0039] like Figure 1-4 As shown, a reinforcing member 13 is fixedly connected between the bracket 10 and the limiting member 11, and between the two brackets 10. An inclined support 4 is fixedly connected to the surface of the bracket 10 and the limiting member 11. An installation member 5 is fixedly connected to the bottom of the inclined support 4. A feed port 6 is provided between the two brackets 10 near the bottom.

[0040] The installation of diagonal supports 4 and mounting parts 5 enhances the stability of the structure. The feed inlet 6 between the supports 10 facilitates material loading by the workers at the bottom.

[0041] like Figure 1-4 As shown, the winch body 7 is located on one side of the inclined support 4 and includes a drum. A steel rope 9 is fixedly connected to the surface of the drum. A pulley is fixedly connected to the top of the bracket 10. The steel rope 9 passes through the pulley and is fixedly connected to the top of the hanger. The base 28 is slidably connected to the bracket 10 and the limiting member 11. A height limiter 8 is provided on one side of the winch body 7 and is electrically connected to the winch body 7.

[0042] The device provides a height limiter 8 to the winch body 7, allowing the user to trigger a deceleration or pause signal at a preset height point to assist in precise stopping, thereby enabling the fixed track 29 to dock with the movable track 14.

[0043] like Figure 1-4 As shown, the surface of the limiting member 11 is provided with several longitudinally distributed limiting holes 12, the surface of the slider 16 is fitted with a locking bolt 17, the locking bolt 17 passes through the limiting hole 12 on one side and is threaded with a limiting nut, the surface of the carrier 26 and the base 28 are both fixedly connected with ear plates, and a pin is inserted between the two ear plates.

[0044] In this device, the height of the movable track 14 can be adjusted according to the height of the user's work platform. When adjusting, the slider 16 is allowed to slide longitudinally along the limiting member 11 to a suitable height. Then, the locking bolt 17 on the surface of the slider 16 passes through the limiting hole 12 on the adjacent side and is locked with the limiting nut. It is convenient and quick for the user to operate and is designed to be user-friendly.

[0045] The working principle of the building engineering lifting device provided by this utility model is as follows:

[0046] First step: The device is equipped with multiple interlocking docking rails 15. Adjacent docking rails 15 are connected by limiting blocks 20 and limiting grooves 19, and then fixed by mounting bolts and mounting nuts. In this way, the user can set up a sufficient number of docking rails 15 and connect them according to the material unloading point in the actual situation. The structure is reasonably designed. In addition, the height of the movable rail 14 in the device can be adjusted according to the height of the user's work platform. When adjusting, let the slider 16 slide along the longitudinal direction of the limiting member 11 to the appropriate height, and then use the locking bolt 17 on the surface of the slider 16 to pass through the limiting hole 12 on the adjacent side and lock it with the limiting nut. It is convenient and quick for the user to operate and the design is user-friendly.

[0047] The second step: In this device, the user can use the winch body 7 to lift the cage 25, raise the carrier 26 inside to the specified height, and align the fixed rail 29 with the movable rail 14 on one side. Then, the user can pull out the pin in the ear plate and pull the carrier 26, allowing the sliding part 27 at the bottom of the carrier 26 to slide along the docking rail 15 on one side to the specified unloading point for unloading. The structural design allows for easy operation by the user. In addition, after the movable rail 14 is set to the height to dock with the platform, the bottom of the docking rail 15 on one side may not be able to stably support the platform surface. Therefore, this device is specially designed with a movable part 24 whose height can be finely adjusted for docking rail 15. When in use, rotate the threaded sleeve to extend the threaded rod 22 out of the outer cylinder 21 to a suitable length until the bottom of the movable part 24 is stably supported on the platform. The structural design is user-friendly.
