Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction machinery technology, and in particular to an elevator steel structure hoisting device for installing cranes. Background Technology
[0002] Many older residential communities lacked elevators. With the renovation of these communities, there's a growing demand for elevator installation. However, due to the lack of pre-reserved elevator shaft locations, the elevators must be installed externally, with a steel structure hoist built along the wall. Since it's just an elevator installation, tower cranes are impractical. Furthermore, many older communities are quite compact, and internal road conditions make using wheeled cranes difficult. Even if they were feasible, the elevator steel structure hoist is constructed step-by-step, meaning materials cannot be hoisted all at once; installation must proceed as needed, significantly increasing construction costs. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an elevator steel structure hoisting device for installing a crane, so as to solve the technical problems in the background art mentioned above.
[0004] The technical solution of this utility model is as follows:
[0005] An elevator steel structure hoisting device for installing a crane includes a bottom mounting frame, a sliding frame, and a top mounting frame arranged in parallel from bottom to top. Four parallel slide rails are vertically welded between the four corners of the bottom mounting frame and the top mounting frame. The sliding frame is vertically installed between the sliding frames and slides up and down along the slide rails. A motor screw assembly is installed at the center of the bottom mounting frame. A threaded sleeve is installed in the middle of the sliding frame. The screw of the motor screw assembly passes through the threaded sleeve and extends vertically to the top mounting frame. A bearing support for fixing the top end of the screw is installed at the bottom of the top mounting frame. A set of telescopic rods that can be extended at both ends are fixed on the upper side of the sliding frame and the lower side of the top mounting frame. The telescopic rods are fixed perpendicular to the sides of the sliding frame and the top mounting frame and are parallel to each other.
[0006] Furthermore, the sliding frame includes a sliding sleeve, a crossbeam, a connecting plate, and a threaded sleeve. The sliding sleeves are respectively fitted onto the slide rails, the crossbeams are arranged in parallel and both ends are welded to the sliding sleeves, the connecting plate is welded between the crossbeams, and the threaded sleeve is installed in the connecting plate.
[0007] Furthermore, the top mounting bracket includes a rectangular frame and a support plate. The support plate is welded to the upper side of the rectangular frame, and the bearing support is fixed to the center of the bottom side of the support plate. A crane flange seat is welded to the upper side of the support plate.
[0008] Furthermore, the telescopic rods are fixed with bolts. The telescopic rod bolts of the sliding frame pass through the crossbeam and the connecting plate, while the telescopic rod bolts of the top mounting frame pass through the rectangular frame and the support plate.
[0009] Furthermore, the telescopic rod has a rectangular cross-section, with a sleeve in the middle and telescopic square tubes at both ends. Both the sleeve and the telescopic square tubes have pin holes, and steel sleeves are welded to the outer edges of both ends of the sleeve.
[0010] The advantages of this utility model are:
[0011] This utility model fixes the crane above the top mounting frame. During the construction of the elevator steel structure hoist, the climbing equipment climbs one section with the elevator steel structure hoist as each section is constructed upwards, thus completing one climb. After that, materials are hoisted and the construction of the hoist continues. After completing one section, the climbing continues. This not only makes installation and transportation convenient but also reduces the cost of use, making it more suitable for elevator retrofitting in old residential areas.

[0016] like Figure 1-2 As shown:
[0017] An elevator steel structure hoisting device for installing a crane includes a bottom mounting frame 1, a sliding frame 2, and a top mounting frame 3 arranged in parallel from bottom to top. Four parallel slide rails 4 are vertically welded between the four corners of the bottom mounting frame 1 and the top mounting frame 3. The sliding frame 2 is vertically installed between the sliding frames and slides up and down along the slide rails 4. A motor screw assembly 5 is installed at the center of the bottom mounting frame 1. A threaded sleeve 24 is installed in the middle of the sliding frame 2. The screw 51 of the motor screw assembly 5 passes through the threaded sleeve 24 and extends vertically to the top mounting frame 3. A bearing support 34 for fixing the top end of the screw 51 is installed at the bottom of the top mounting frame 3. A set of telescopic rods 6 that can be extended and retracted at both ends are fixed on the upper side of the sliding frame 2 and the lower side of the top mounting frame 3. The telescopic rods 6 are fixed perpendicular to the sides of the sliding frame 2 and the top mounting frame 3 and are parallel to each other.
[0018] Working Principle: This utility model is mainly used for installing cranes / winches to facilitate the hoisting of materials. The crane is fixed above the top mounting frame 3. During the construction of the elevator steel structure hoist, the climbing equipment climbs one section with the elevator steel structure hoist as each section is constructed upwards. During the climbing process, the motor screw assembly 5 first drives the sliding frame 2 to move upwards to the previous hoist section. Then, the two ends of the telescopic rod 6 on the sliding frame 2 are pulled out and fixed to the crossbeam 22 of the elevator hoist. After that, the telescopic rod 6 of the top mounting frame 3 is released and retracted. At this time, the motor screw assembly 5 reverses, and the screw drives the sliding frame 2 downwards. Since the sliding frame 2 has been fixed, the climbing equipment will be lifted upwards. Then, the telescopic rod 6 of the top mounting frame 3 is pulled out and fixed to the top of the hoist. This completes one climb. After that, materials are hoisted and the construction of the hoist continues. After completing one section, the climbing continues.
[0019] The structure of the sliding frame 2 includes a sliding sleeve 21, a crossbeam 22, a connecting plate 23, and a threaded sleeve 24. The sliding sleeve 21 is respectively fitted on the slide rail 4. The crossbeam 22 is arranged in parallel and both ends are welded to the sliding sleeve 21. The connecting plate 23 is welded between the crossbeams 22. The threaded sleeve 24 is installed in the connecting plate 23. The top mounting frame 3 includes a rectangular frame 31 and a support plate 32. The support plate 32 is welded to the upper side of the rectangular frame 31. The bearing support 34 is fixed to the bottom center of the support plate 32. A crane flange seat 33 is welded to the upper side of the support plate 32 to facilitate the installation of the crane / winch.
[0020] For ease of disassembly and transportation, the telescopic rod 6 is fixed with bolts. For stability, the bolts of the telescopic rod 6 of the sliding frame 2 pass through the crossbeam 22 and the connecting plate 23, and the bolts of the telescopic rod 6 of the top mounting frame 3 pass through the rectangular frame 31 and the support plate 32.
[0021] As an optimized solution, the telescopic rod 6 has a rectangular cross-section, with a sleeve 61 in the middle and telescopic square tubes 62 at both ends. Both the sleeve 61 and the telescopic square tubes 62 have pin holes 63 to facilitate fixing to the derrick. Steel sleeves 611 are welded to the outer edges of both ends of the sleeve 61 to avoid the top end of the sleeve 61 having a notch.
[0022] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
