Description

Technical Field

[0001] This utility model relates to the field of steel space frames, and in particular to a high-altitude sliding device for steel space frames. Background Technology

[0002] A steel space frame is a spatial structure system composed of multiple steel members connected by nodes in a specific grid pattern. It features light weight, high rigidity, and good seismic performance, and is widely used in large-span buildings such as stadiums, airport terminals, and industrial plants. Its members are mostly made of high-strength steel, and the node types include bolted ball joints and welded ball joints. It can be designed as a flat or curved space frame according to load requirements. For steel space frames installed at high altitudes, where scaffolding is inconvenient to erect, the steel space frame is usually constructed on one side of the site and then moved to the designated location using a sliding device.

[0003] In related technologies, after the high-altitude steel space frame is erected, it is mainly moved by sliding devices. Traditional sliding devices usually consist of sliding tracks, load-bearing pulleys, traction equipment, and synchronous control systems. The tracks are usually fixed to temporary supports or existing structures at high altitudes. Several load-bearing pulleys are installed and are rigidly connected to the bottom of the steel space frame. During construction, the traction end of the traction equipment is rigidly connected to the steel space frame. By starting the traction equipment, the steel space frame can be controlled to gradually slide along the track to the designed position, thus completing the sliding construction.

[0004] However, by controlling the movement of the steel space frame through traction equipment, the traction force between the traction equipment and the steel space frame may be concentrated, which may cause deformation of the overall structure of the steel space frame during the traction process.

[0005] Therefore, it is necessary to provide a high-altitude sliding device for steel space frames to solve the above problems. Utility Model Content

[0006] To address the technical problem that the traction force between the traction device and the steel space frame may be concentrated in the aforementioned method of controlling the movement of the steel space frame through traction equipment, which may lead to deformation of the overall structure of the steel space frame during the traction process, this utility model provides a high-altitude sliding device for steel space frames.

The sliding rollers are symmetrically and fixedly arranged in pairs at the bottom of each side of the high-altitude steel space frame, and are located inside the U-shaped slide rails. The device also includes a drive mechanism and a transmission mechanism. Two drive mechanisms are provided, each located at the bottom of each side of the high-altitude steel space frame, with each drive mechanism corresponding to a specific U-shaped slide rail. A plurality of transmission mechanisms are provided. The transmission mechanisms are symmetrically arranged in pairs at the bottom of both sides of the high-altitude steel grid frame. The drive mechanism is movably arranged between the symmetrically arranged transmission mechanisms to drive the transmission mechanisms to rotate. The end of the transmission mechanism away from the drive mechanism is fixedly connected to one side of the sliding roller to drive the sliding roller to rotate. A protective shell and limiting plates are provided. Multiple protective shells are provided. The connection between the drive mechanism and the symmetrically arranged transmission mechanisms is located inside the protective shell. A number of limiting plates are provided. These limiting plates are symmetrically fixed in pairs at the bottom of both sides of the high-altitude steel grid frame. The inner wall of each limiting plate is rotatably connected to the outer wall of each transmission mechanism.

[0008] Preferably, L-shaped support frames are fixedly connected to the bottom of both sides of the high-altitude steel grid frame, and each drive mechanism is fixedly mounted on each L-shaped support frame.

[0009] Preferably, the sliding roller includes an ear plate, the upper end face of which is fixedly connected to the bottom of the high-altitude steel grid frame, a first shaft is rotatably connected to the inner wall of the ear plate, one end of the first shaft is fixedly connected to one end of the transmission mechanism, and wheel bodies are fixedly connected to both ends of the outer wall of the first shaft.

[0010] Preferably, the drive mechanism includes a motor, one side of which is fixedly connected to one side of the L-shaped support frame. The output end of the motor is fixedly connected to a second shaft through the L-shaped support frame. A plurality of first bevel gears are uniformly fixedly connected to the outer wall of the second shaft. The outer wall of the first bevel gear meshes with one end of the transmission mechanism. Each first bevel gear is located inside each of the protective shells.

[0011] Preferably, the transmission mechanism includes a third shaft, the outer wall of which is rotatably connected to the inner wall of the limiting plate, one end of which is fixedly connected to one end of the first shaft, and the other end of which is fixedly connected to a second bevel gear, the outer wall of which meshes with the outer wall of the first bevel gear.

[0012] Preferably, the protective shell includes a rectangular shell, the second shaft passes through the rectangular shell, the third shaft passes through the rectangular shell, the first bevel gear and the second bevel gear are located inside the rectangular shell, a connecting column is fixedly connected to the upper surface of the rectangular shell, and the upper end face of the connecting column is fixedly connected to the bottom of the high-altitude steel grid frame.

[0013] Compared with related technologies, the high-altitude sliding device for steel space frames provided by this utility model has the following beneficial effects:

[0014] 1. This high-altitude sliding device for steel space frames can disperse localized stress during the sliding process: the U-shaped guide rail's groove design restricts the sliding direction of the steel space frame; the rolling contact between the sliding rollers and the U-shaped guide rail reduces resistance during sliding; two drive mechanisms are respectively located at the bottom of both sides of the high-altitude steel space frame and within the U-shaped guide rail; several transmission mechanisms are symmetrically distributed in pairs at the bottom of both sides of the steel space frame; the drive mechanisms are movably connected between the symmetrical transmission mechanisms; synchronous activation of the two drive mechanisms can distribute the driving force... The force is evenly transmitted to each transmission mechanism, and then the transmission mechanism drives all the sliding rollers to rotate synchronously, so as to realize multi-point distributed drive. This can replace the traditional centralized traction force mode, prevent single-point force concentration of high-altitude steel space frame, reduce the deformation risk of high-altitude steel space frame structure, and the protective shell can wrap the connection between the drive mechanism and the transmission mechanism to prevent high-altitude dust and rainwater from corroding the transmission components. The limit plate can limit the installation position of the transmission mechanism to prevent the transmission mechanism from swaying when under force, and further improve the transmission of driving force.

[0015] 2. The steel space frame high-altitude sliding device has ear plates that limit the installation position of the first shaft, which in turn limits the installation position of the wheel. An L-shaped support frame limits the installation position of the motor. The starting motor, via the second shaft, drives multiple first bevel gears to rotate. These second bevel gears, in conjunction with the rotating first bevel gears, control the rotation of the third shaft. The rotation of the third shaft drives the rotation of the first shaft, which in turn drives the wheel. Connecting columns limit the installation position of the rectangular housing, which protects the first and second bevel gears. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1 to 5 A high-altitude sliding device for a steel space frame includes: a high-altitude steel space frame 1 and two U-shaped slide rails 2. The bottom of both sides of the high-altitude steel space frame 1 is located inside the two U-shaped slide rails 2. A plurality of sliding rollers 3 are symmetrically and fixedly connected to the bottom of both sides of the high-altitude steel space frame 1 in pairs. The sliding rollers 3 are symmetrically and fixedly arranged in pairs at the bottom of both sides of the high-altitude steel space frame 1, and are located inside the U-shaped slide rails 2. A driving mechanism 4 and a transmission mechanism 5 are also included. Two driving mechanisms 4 are provided, each located at the bottom of one of the two sides of the high-altitude steel space frame 1, with each driving mechanism 4 corresponding to a specific U-shaped slide rail 2. A plurality of transmission mechanisms 5 are provided. The transmission mechanisms 5 are symmetrically arranged in pairs at the bottom of both sides of the high-altitude steel grid frame 1. The drive mechanism 4 is movably arranged between the symmetrically arranged transmission mechanisms 5 to drive the transmission mechanisms 5 to rotate. The end of the transmission mechanism 5 away from the drive mechanism 4 is fixedly connected to one side of the sliding roller 3 to drive the sliding roller 3 to rotate. There are protective shells 6 and limiting plates 7. Multiple protective shells 6 are provided. The connection between the drive mechanism 4 and the symmetrically arranged transmission mechanisms 5 is located inside the protective shell 6. Several limiting plates 7 are provided. Several limiting plates 7 are symmetrically fixed in pairs at the bottom of both sides of the high-altitude steel grid frame 1. The inner wall of each limiting plate 7 is rotatably connected to the outer wall of each transmission mechanism 5.

[0024] In the specific implementation process, the high-altitude steel grid 1 and two U-shaped slide rails 2 in the high-altitude sliding device of the steel grid frame are the main load-bearing structures. The bottom of both sides of the high-altitude steel grid 1 is embedded in the two U-shaped slide rails 2 to form a sliding guide structure. Through the groove design of the U-shaped slide rails 2, the sliding direction of the high-altitude steel grid 1 can be restricted to prevent the high-altitude steel grid 1 from shifting laterally. At the bottom of both sides of the high-altitude steel grid 1, several sliding rollers 3 are symmetrically fixedly connected in pairs. The sliding rollers 3 are all located inside the U-shaped slide rails 2. The rolling contact between the sliding rollers 3 and the U-shaped slide rails 2 reduces the resistance during sliding. Furthermore, this high-altitude sliding device for the steel space frame is equipped with two drive mechanisms 4 and several transmission mechanisms 5. The two drive mechanisms 4 are respectively located at the bottom of both sides of the high-altitude steel space frame 1 and inside the U-shaped slide rails 2. The several transmission mechanisms 5 are symmetrically distributed in pairs at the bottom of both sides of the steel space frame. The drive mechanisms 4 are movably connected between the symmetrical transmission mechanisms 5, which can evenly transmit the driving force to each transmission mechanism. The structure 5, through the fixed connection between the transmission mechanism 5 and the sliding rollers 3, drives all the sliding rollers 3 to rotate synchronously, so as to realize multi-point distributed drive and prevent single-point force concentration of the high-altitude steel grid 1. Furthermore, multiple protective shells 6 are evenly arranged at the bottom of both sides of the high-altitude steel grid 1. The protective shells 6 can cover the connection between the drive mechanism 4 and the transmission mechanism 5 to prevent the transmission components from being corroded by high-altitude dust and rainwater, thereby ensuring transmission stability. The bottom of both sides of the high-altitude steel grid 1 is symmetrically fixed in pairs. Several limiting plates 7 are installed, and the inner wall of each limiting plate 7 is rotatably connected to the outer wall of the corresponding transmission mechanism 5. Thus, the installation position of the transmission mechanism 5 can be restricted by the limiting plates 7 to prevent the transmission mechanism 5 from swaying when subjected to force, thereby further improving the transmission of driving force. Through the above structural design, the high-altitude sliding device of this steel space frame can transform the traditional centralized traction force mode into multi-point synchronous drive, thereby dispersing the local stress of the high-altitude steel space frame 1 during the sliding process, so as to reduce the deformation risk of the high-altitude steel space frame 1 structure.

[0025] Specifically, it needs to be explained that the two drive mechanisms 4 need to be controlled by a linkage and synchronization control system during operation in order to prevent the deformation of the high-altitude steel grid 1 caused by uneven driving force on both sides. The top of the limit plate 7 is rigidly connected to the steel rod of the high-altitude steel grid 1.

[0026] See Figure 3 As shown, L-shaped support frames 8 are fixedly connected to the bottom of both sides of the high-altitude steel grid frame 1, and each drive mechanism 4 is fixedly installed on each L-shaped support frame 8.

[0027] In the specific implementation process, the L-shaped support frame 8 can restrict the installation position of one end of the drive mechanism 4, thereby improving the stability of the installation and operation of the drive mechanism 4.

[0028] Specifically, it needs to be explained that the L-shaped support frame 8 is rigidly connected on one side to the steel members of the high-altitude steel space frame 1.

[0029] See Figure 3 , Figure 4 and Figure 5 As shown, the sliding roller 3 includes a lug plate 301. The upper end face of the lug plate 301 is fixedly connected to the bottom of the high-altitude steel grid 1. The inner wall of the lug plate 301 is rotatably connected to a first shaft 302. One end of the first shaft 302 is fixedly connected to one end of the transmission mechanism 5. Both ends of the outer wall of the first shaft 302 are fixedly connected to wheel bodies 303.

[0030] In the specific implementation process, the ear plate 301 can limit the installation position of the first shaft 302, the first shaft 302 can limit the installation position of the wheel 303, and one end of the first shaft 302 is connected to the transmission mechanism 5, so that when the transmission mechanism 5 is running, the first shaft 302 can drive the wheel 303 to rotate.

[0031] Specifically, it needs to be explained that the top of the ear plate 301 is rigidly connected to the ball node of the high-altitude steel space frame 1.

[0032] See Figure 3 , Figure 4 and Figure 5 As shown, the drive mechanism 4 includes a motor 401. One side of the motor 401 is fixedly connected to one side of the L-shaped support frame 8. The output end of the motor 401 passes through the L-shaped support frame 8 and is fixedly connected to a second shaft 402. Multiple first bevel gears 403 are evenly fixedly connected to the outer wall of the second shaft 402. The outer wall of the first bevel gear 403 meshes with one end of the transmission mechanism 5. Each first bevel gear 403 is located inside each protective shell 6.

[0033] In the specific implementation process, the L-shaped support frame 8 can restrict the installation position of the motor 401. The starting motor 401 can drive multiple first bevel gears 403 to rotate through the second shaft 402. The rotation of the first bevel gears 403 can drive the transmission mechanism 5 to operate.

[0034] Specifically, it should be noted that the motor 401 is a device with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the motor 401 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation.

[0035] See Figure 3 , Figure 4 and Figure 5As shown, the transmission mechanism 5 includes a third shaft 501, the outer wall of the third shaft 501 is rotatably connected to the inner wall of the limiting plate 7, one end of the third shaft 501 is fixedly connected to one end of the first shaft 302, and the other end of the third shaft 501 is fixedly connected to a second bevel gear 502, the outer wall of the second bevel gear 502 meshes with the outer wall of the first bevel gear 403.

[0036] In the specific implementation process, the second bevel gear 502 cooperates with the rotating first bevel gear 403 to control the rotation of the third shaft 501, and the rotation of the third shaft 501 can drive the first shaft 302 to rotate.

[0037] See Figure 3 , Figure 4 and Figure 5 As shown, the protective shell 6 includes a rectangular shell 601, a second shaft 402 passing through the rectangular shell 601, a third shaft 501 passing through the rectangular shell 601, a first bevel gear 403 and a second bevel gear 502 located inside the rectangular shell 601, and a connecting column 602 fixedly connected to the upper surface of the rectangular shell 601, with the upper end face of the connecting column 602 fixedly connected to the bottom of the high-altitude steel grid 1.

[0038] In the specific implementation process, the installation position of the rectangular housing 601 can be restricted by the connecting column 602, and the rectangular housing 601 can protect the first bevel gear 403 and the second bevel gear 502.

[0039] Specifically, it needs to be explained that the top of the connecting column 602 is rigidly connected to the steel rod of the high-altitude steel space frame 1.

[0040] The working principle of the high-altitude sliding device for steel space frame provided by this utility model is as follows:

[0041] When the high-altitude sliding device for the steel space frame is working, the two drive mechanisms 4 controlled by the linkage and synchronization control system operate synchronously. The motor 401 starts and drives the second shaft 402 to rotate, which in turn causes multiple first bevel gears 403 to rotate. The first bevel gears 403 mesh with the second bevel gears 502 in the transmission mechanism 5, which drives the third shaft 501 to rotate. One end of the third shaft 501 is fixedly connected to the first shaft 302, thereby driving the first shaft 302 to rotate. The wheels 303 at both ends of the outer wall of the first shaft 302 rotate accordingly. Since the wheels 303 are located inside the U-shaped slide rail 2, the sliding of the high-altitude steel space frame 1 can be achieved through the rolling contact between the wheels 303 and the U-shaped slide rail 2.

[0042] The rectangular shell 601 of the protective shell 6 is fixed to the bottom of the high-altitude steel grid 1 by the connecting column 602, and the first bevel gear 403 and the second bevel gear 502 are wrapped inside to prevent dust and rainwater corrosion. The top of the limiting plate 7 is rigidly connected to the steel rod of the high-altitude steel grid 1. The inner wall of the limiting plate 7 is rotatably connected to the outer wall of the third shaft 501 to limit the installation position of the transmission mechanism 5, improve the stable transmission of driving force, and perform multi-point distributed driving.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
