Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, and more specifically to a lift for building engineering. Background Art

[0002] When the existing construction lift is loaded with heavy objects and a large number of workers, it may shake or tilt, affecting safety. After long-term use, it is easy to cause structural imbalance, leading to high-altitude falling accidents. Content of the Utility Model

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a lift for building engineering to solve the problems existing in the above-mentioned background art, that is, when the existing construction lift is loaded with heavy objects and a large number of workers, it may shake or tilt, affecting safety. After long-term use, it is easy to cause structural imbalance, leading to high-altitude falling accidents.

[0004] The utility model provides the following technical solutions: including a lift floor plate, four first limit rails are fixedly installed at the top end of the lift floor plate, second limit rails are arranged at the top ends of the first limit rails, sliding grooves are formed on both the first limit rails and the second limit rails, a lift main body is movably installed at the top end of the lift floor plate, four limit sliders are fixedly installed on both sides of the lift main body, and the limit sliders are all slidably located in the sliding grooves of the first limit rails and the second limit rails. Two steel cables are fixedly installed at the top end of the lift main body, driving motors are arranged at the ends of the steel cables, the driving motors are symmetrically distributed along the central axis of the lift main body, and the driving directions of the driving motors are opposite. When in use, the two driving motors are axially symmetrically distributed along the central axis of the lift main body. This distribution method can make the force of the steel cables more stable and uniform when lifting the lift main body, increase the invisible stress area. At the same time, the limit sliders on the lift main body slide strictly along the inner part of the sliding grooves formed by the first limit rails and the second limit rails, further restricting the movement trajectory of the lift main body when moving up and down, preventing it from tilting and shaking. Compared with the traditional lift, its safety factor is higher and its structural strength is better, effectively solving the problems that when the existing construction lift is loaded with heavy objects and a large number of workers, it may shake or tilt, affecting safety, and after long-term use, it is easy to cause structural imbalance, leading to high-altitude falling accidents.

[0005] Furthermore, a plurality of structural strengthening plates are fixedly installed between the second limit rails. The main material of the structural strengthening plates is stainless steel bars, and the structural strengthening plates and the second limit rails are connected by threaded rods. When in use, the structural strengthening plates can further enhance the structural strength between the second limit rails, making the structural stability of the whole frame higher and further preventing the frame from toppling.

[0006] Furthermore, combined mounting plates are fixedly installed at both the top and bottom ends of the first limiting rail and the second limiting rail. Threaded holes are provided on the combined mounting plates. The first limiting rail and the second limiting rail are connected to each other through the combined mounting plates, and a plurality of threaded rods are installed through the connected combined mounting plates. During use, users can freely combine the first limiting rail and the second limiting rail according to the height of the construction building. The combination of multiple first limiting rails and second limiting rails can make the lifting height of the main body of the lift higher and the applicable range wider.

[0007] Furthermore, at least four buffer shock-absorbing plates are fixedly installed at the bottom end of the main body of the lift. Steel plate pads are fixedly installed at the bottom ends of the buffer shock-absorbing plates. During use, when the main body of the lift is sent to the lowest position by the driving motor, the buffer shock-absorbing plates will come into contact with the lift bottom plate first and provide impact buffering for the main body of the lift to prevent the bottom end of the main body of the lift from directly hitting the lift bottom plate.

[0008] Furthermore, a plurality of soil-inserting fixing pins are fixedly installed at the bottom end of the lift bottom plate. A plurality of stainless steel limiting disks are fixedly installed on the soil-inserting fixing pins. During use, after the lift bottom plate is installed on the ground, the soil-inserting fixing pins can penetrate into the soil to further reinforce the connection between the lift bottom plate and the ground.

[0009] Furthermore, the steel cable is made of high-carbon steel, and the first limiting rail and the second limiting rail are both made of alloy steel.

[0010] The technical effects and advantages of the present utility model:

[0011] 1. By providing the first limiting rail, the second limiting rail, the main body of the lift, the limiting slider, and the driving motor, the present utility model effectively solves the problems that the existing construction hoist may shake or tilt when carrying heavy loads and a large number of workers, affecting safety, and is prone to structural imbalance after long-term use, leading to high-altitude falling accidents.

[0012] 2. By providing the structural strengthening plate, during use, the structural strengthening plate can further enhance the structural strength between the second limiting rails, making the structural stability of the entire framework higher and further preventing the framework from tipping over.

In addition, the forms of each structure described in the following embodiments are merely examples. A construction hoist related to the present utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0019] Embodiment 1:

[0020] Referring to Figure 1 and Figure 2 , the present utility model provides a construction hoist, including a lifting ladder bottom plate 100. Four first limit rails 110 are fixedly installed at the top end of the lifting ladder bottom plate 100. Second limit rails 111 are provided at the top ends of the first limit rails 110. Chutes are opened on both the first limit rails 110 and the second limit rails 111. A lifting ladder main body 112 is movably installed at the top end of the lifting ladder bottom plate 100. Four limit sliders 113 are fixedly installed on both sides of the lifting ladder main body 112. The limit sliders 113 are all located in the chutes of the first limit rails 110 and the second limit rails 111 and slide therein. Two steel cables are fixedly installed at the top end of the lifting ladder main body 112. Driving motors 114 are provided at the ends of the steel cables. The driving motors 114 are all symmetrically distributed along the central axis of the lifting ladder main body 112, and the driving directions of the driving motors 114 are all opposite.

[0021] A plurality of structural reinforcement plates 115 are fixedly installed between the second limit rails 111. The main material of the structural reinforcement plates 115 is stainless steel bars. The structural reinforcement plates 115 and the second limit rails 111 are connected by threaded rods.

[0022] Combined mounting plates 116 are fixedly installed at the top and bottom ends of the first limit rails 110 and the second limit rails 111. Threaded holes are opened on the combined mounting plates 116. The first limit rails 110 and the second limit rails 111 are connected to each other through the combined mounting plates 116, and a plurality of threaded rods are penetrated and installed on the connected combined mounting plates 116.

[0023] Working principle: During use, the two driving motors 114 are axially symmetrically distributed along the central axis of the elevator main body 112. This distribution method can make the force on the steel cable more stable and uniform when lifting the elevator main body 112, increasing the invisible stress area. At the same time, the limit sliders 113 on the elevator main body 112 slide strictly inside the chute formed by the first limit rail 110 and the second limit rail 111, further restricting the trajectory of the elevator main body 112 when moving up and down, preventing it from tilting and shaking. Compared with traditional elevators, its safety factor is higher and its structural strength is better.

[0024] Embodiment 2:

[0026] A plurality of soil-inserting fixing pins 118 are fixedly installed at the bottom end of the elevator floor 100, and a plurality of stainless steel limit discs are fixedly installed on the soil-inserting fixing pins 118.

[0027] The steel cable is made of high-carbon steel, and the first limit rail 110 and the second limit rail 111 are both made of alloy steel.

[0028] Working principle: During use, after the elevator floor 100 is installed on the ground, the soil-inserting fixing pins 118 can penetrate deep into the soil to further strengthen the connection between the elevator floor 100 and the ground.

[0029] Finally, the following points should be noted: In the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the internal communication of two components, and can be directly connected. "Up", "down", "left", "right", etc. are only used to represent relative position relationships.
