Description

Technical Field

[0001] The utility model relates to the technical field of steel members, in particular to a pre-assembly structure for steel members. Background Art

[0002] Steel structures, as one of the cornerstones of modern building structures, are widely used in various large-scale facilities and super high-rise buildings. In construction projects, pre-assembly of steel members is an important technical means to ensure the installation quality of steel structures and improve construction efficiency. Pre-assembly usually refers to assembling multiple small components into larger components on a platform temporarily built in a factory or on-site according to the requirements of design drawings, so as to facilitate transportation and on-site installation. This approach can reduce on-site workload, improve accuracy, and help discover and solve potential design problems.

[0003] The existing patent (publication number: CN221627691U) discloses "a pre-assembly structure for steel members, characterized in that it includes a bottom plate (1): two pairs of rollers (2) are fixedly connected to the bottom of the bottom plate (1), and an adjustment chamber (3) is fixedly connected to the top of the bottom plate (1). A pair of first hydraulic cylinders (4) are fixedly connected to the inner wall of the bottom of the adjustment chamber (3). The output shafts of the pair of first hydraulic cylinders (4) are fixedly connected to a cross plate (5). A pair of positioning grooves (6) are fixedly connected to the top of the cross plate (5). The positioning grooves (6) penetrate through the top of the adjustment chamber (3). A second hydraulic cylinder (7) is fixedly connected to the inner wall of the positioning groove (6). The output shaft of the second hydraulic cylinder (7) is fixedly connected to a limiting block (8). A support plate (19) is fixedly connected to the top of the pair of limiting blocks (8). A circular groove (9) is formed in the top of the support plate (19). A disc (10) is arranged in the circular groove (9). Two pairs of vertical blocks (11) are fixedly connected to the top of the disc (10). Electric telescopic rods (12) are fixedly connected to the side walls of each pair of vertical blocks (11) away from each other. The output shafts of the electric telescopic rods (12) penetrate through the vertical blocks (11) and are fixedly connected to clamping blocks (13). A transmission mechanism is arranged below the support plate (19). The beneficial effect is that through the settings of the adjustment chamber, the first hydraulic cylinder, the cross plate, the positioning groove and the support plate, the height can be adjusted, and through the settings of the motor, the first gear, the second gear and the rotating rod, the angle of the device can be adjusted, thereby reducing the physical consumption of workers and improving the convenience of steel member assembly".

[0004] The inventor found the following problems in the prior art during the implementation of this application:

[0005] 1. The device realizes height adjustment through an adjustment bin, a first hydraulic cylinder, a cross plate, a positioning groove and a support plate. Then, multiple electric telescopic rods are used to push the clamping blocks to clamp the steel member. When it is necessary to adjust the angle of the steel member, the motor is started to drive the second gear to rotate, thereby driving the first gear and the rotating rod to rotate. The rotating rod drives the disc to rotate, and then the angle of the steel member is adjusted. Although the functions of height adjustment and angle adjustment are realized, due to the use of multiple electric telescopic rods, motors, gears and rotating rods, the overall structure is complex, and the manufacturing and maintenance costs are relatively high.

[0006] 2. Two pairs of rollers are fixedly connected to the bottom of the bottom plate of the device. When the first hydraulic cylinder is started to push the cross plate and the positioning groove to move upward, the steel member is thus pushed to the installation position. However, the rollers lack a fixing device, and when the steel member is pushed, the rollers may move, affecting the assembly of the steel member.

[0007] Therefore, those skilled in the art provide a pre-assembly structure for steel members to solve the problems raised in the above background technology. Summary of the Utility Model

[0008] The purpose of the present utility model is to solve the deficiencies existing in the prior art, and a pre-assembly structure for steel members is proposed. Through an adjustment mechanism, the second motor drives the chuck to rotate to clamp the steel member. Then, the moving frame can be moved by rotating the screw rod, so that the second motor drives the rotating disc to rotate. The operation is convenient, the cost is saved, and when the steel member is lifted, the universal wheels will disengage from the ground, thereby enhancing the stability and improving the assembly efficiency.

[0009] To achieve the above purpose, the present utility model provides the following technical solutions:

[0010] A pre-assembly structure for steel members, including a device main body and a base. An adjustment mechanism is arranged at the upper end inside the device main body. The adjustment mechanism includes two buffer pads, two clamping plates, a rotating disc, a chuck, a sliding rod, a first internal gear ring, a gear, a second internal gear ring, a rotating shaft, a moving frame, a second motor, a rotating block and a screw rod;

[0011] A first motor is fixedly arranged on one side inside the base. The output end of the first motor is fixedly provided with a bidirectional lead screw. Two sliders are threadedly connected to the outside of the bidirectional lead screw. Two guide rods are fixedly arranged at the lower end inside the base. The front and rear ends of the two sliders are rotatably provided with support frames. Two rotating plates are rotatably arranged at the lower ends of the two sliders. A support plate is rotatably arranged between the lower ends of the four rotating plates. Four universal wheels are fixedly arranged at the lower end of the base.

[0012] Further, the outside of the moving frame is slidably arranged at the lower end inside the device main body, the outside of the second motor is fixedly arranged inside the moving frame, and the lower end of the rotating shaft is fixedly arranged at the output end of the second motor.

[0013] Further, the outside of the first internal gear ring is fixedly arranged inside the chuck, and the outside of the second internal gear ring is fixedly arranged inside the rotating disc.

[0014] Further, the inside of the gear is fixedly arranged outside the rotating shaft, and the inside of the first internal gear ring is meshed and connected to the outside of the gear.

[0015] Further, the upper end of the sliding rod is rotatably arranged at the upper end inside the rotating disc, and the outside of the sliding rod is slidably arranged at the upper end inside the rotating shaft.

[0016] Further, the outside of the screw rod is rotatably arranged at one side inside the device main body, the upper end of the rotating block is threadedly connected to the outside of the screw rod, and one side of the rotating block is rotatably arranged at one side of the moving frame.

[0017] Further, the two opposite sides of the two buffer pads are respectively fixedly arranged on the two opposite sides of the two clamping plates, the outside of the rotating disc is rotatably arranged at the upper end of the device main body, the lower ends of the two clamping plates are slidably arranged at the upper end of the chuck, and the outside of the chuck is rotatably arranged at the upper end inside the rotating disc.

[0018] Further, the inside of the two sliders are both slidably arranged on the outside of the two guide rods, one side of the bidirectional lead screw is rotatably arranged at one side inside the base, and the upper end of the support frame is rotatably arranged at the lower end of the device main body.

[0019] The utility model has the following beneficial effects:

[0020] 1. For a steel member pre-assembly structure proposed by the utility model, when in use, place the steel member on the upper end of the rotating disc, then start the second motor to drive the rotating shaft and the gear to rotate. At this time, the gear meshes with the first internal gear ring, so that the chuck rotates to drive the two clamping plates to move towards each other, thereby realizing the clamping of the steel member. The buffer pads can protect the steel member from damage. Then, rotate the screw rod to make the rotating block move inwards and rotate, thereby pushing the moving frame to slide downwards inside the device main body. As the moving frame descends, it will drive the second motor to move synchronously, and the rotating shaft will drive the gear to move synchronously, so that the gear gradually disengages from the first internal gear ring and finally meshes with the second internal gear ring. Subsequently, stop rotating the screw rod. When adjusting the angle of the steel member, drive the rotating shaft to drive the gear to rotate through the second motor, so that the gear drives the rotating disc to rotate, thereby realizing angle adjustment. The entire operation process is not only convenient to operate, but also reduces the manufacturing cost, and can clamp steel members of different sizes.

[0021] 2. For a pre-assembly structure of steel members proposed by the present utility model, when the steel members need to be pushed to the installation position, the first motor in the base is started to rotate the bidirectional lead screw. The rotation of the bidirectional lead screw will cause two sliders to move towards each other, thereby driving the main body of the device to rise through the support frame. At the same time, the movement of the sliders will also cause the rotating plate to rotate, driving the support plate connected to the rotating plate to move downward and contact the ground. As the support plate gradually contacts the ground, the universal wheels at the lower end of the base will gradually leave the ground, thereby improving the stability of the steel members during pre-assembly.

[0029] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figures 1-5 , an embodiment provided by the present utility model:

[0031] A pre-assembly structure for steel members, comprising a device main body 1 and a base 2. An adjusting mechanism 3 is arranged at the upper end inside the device main body 1. The adjusting mechanism 3 includes two buffer pads 301, two clamping plates 302, a rotating disk 303, a chuck 304, a sliding rod 305, a first internal gear ring 306, a gear 307, a second internal gear ring 308, a rotating shaft 309, a moving frame 310, a second motor 311, a rotating block 312 and a screw rod 313. The outside of the moving frame 310 is slidably arranged at the lower end inside the device main body 1. The outside of the second motor 311 is fixedly arranged inside the moving frame 310. The lower end of the rotating shaft 309 is fixedly arranged at the output end of the second motor 311. The outside of the first internal gear ring 306 is fixedly arranged inside the chuck 304. The outside of the second internal gear ring 308 is fixedly arranged inside the rotating disk 303. The inside of the gear 307 is fixedly arranged outside the rotating shaft 309. The inside of the first internal gear ring 306 is meshed and connected to the outside of the gear 307. The upper end of the sliding rod 305 is rotatably arranged at the upper end inside the rotating disk 303. The outside of the sliding rod 305 is slidably arranged at the upper end inside the rotating shaft 309. The outside of the screw rod 313 is rotatably arranged at one side inside the device main body 1. The upper end of the rotating block 312 is threadedly connected to the outside of the screw rod 313. One side of the rotating block 312 is rotatably arranged at one side of the moving frame 310. The two opposite sides of the two buffer pads 301 are respectively fixedly arranged on the two opposite sides of the two clamping plates 302. The outside of the rotating disk 303 is rotatably arranged at the upper end of the device main body 1. The lower ends of the two clamping plates 302 are slidably arranged at the upper end of the chuck 304. The outside of the chuck 304 is rotatably arranged at the upper end inside the rotating disk 303;

[0032] Specifically, during operation, first place the steel member to be processed securely on the upper surface of the rotating disk 303. Subsequently, activate the second motor 311 inside the device main body 1, causing the rotating shaft 309 to rotate and transmit the rotation to the gear 307. At this time, the gear 307 meshes with the first internal gear ring 306. The rotation of the gear 307 will then cause the first internal gear ring 306 to rotate, thereby driving the chuck 304 to rotate. The rotation of the chuck 304 will cause the two clamping plates 302 on the chuck 304 to move towards each other, thus clamping the steel member on the rotating disk 303. At this time, the buffer pads 301 on the opposite sides of the clamping plates 302 can protect the steel member from clamping damage, reduce the wear of the steel member during pre-assembly, extend its service life. Next, by rotating the screw 313, drive the rotating block 312 connected to its outside to move towards the second motor 311 and perform a rotational movement, thereby guiding the moving frame 310 to slowly slide down inside the device main body 1. Since the second motor 311 is inside the moving frame 310, when the moving frame 310 moves downward, the second motor 311 and the rotating shaft 309 and gear 307 at its output end will move synchronously. During this process, the inside of the rotating shaft 309 will slide on the outside of the sliding rod 305. At the same time, the meshing state between the gear 307 and the first internal gear ring 306 gradually loosens. When the gear 307 is driven to a preset position, it will establish a new meshing relationship with the second internal gear ring 308. At this time, stop rotating the screw 313. If it is necessary to adjust the angle of the steel member to meet the installation requirements, the second motor 311 can be started again. Since the gear 307 is already meshed with the second internal gear ring 308, the rotation of the second motor 311 will directly drive the rotating disk 303 to rotate through the gear 307. The rotation of the rotating disk 303 can achieve the angle adjustment of the steel member, which not only improves the efficiency and accuracy of steel member assembly but also improves the flexibility of pre-assembly.

[0033] Refer to Figures 1-2 , a first motor 10 is fixedly arranged on one side inside the base 2. A bidirectional lead screw 6 is fixedly arranged at the output end of the first motor 10. Two sliders 7 are threadedly connected to the outside of the bidirectional lead screw 6. Two guide rods 5 are fixedly arranged at the lower end inside the base 2. Support frames 4 are rotatably arranged at the front and rear ends of the two sliders 7. Two rotating plates 11 are rotatably arranged at the lower ends of the two sliders 7. A support plate 8 is rotatably arranged between the lower ends of the four rotating plates 11. Four universal wheels 9 are fixedly arranged at the lower end of the base 2. The inside of the two sliders 7 is slidably arranged on the outside of the two guide rods 5. One side of the bidirectional lead screw 6 is rotatably arranged on one side inside the base 2. The upper end of the support frame 4 is rotatably arranged at the lower end of the device main body 1;

[0034] Specifically, when the steel member needs to be moved to the installation position, the first motor 10 inside the base 2 is started, the first motor 10 operates and drives the bidirectional lead screw 6 to rotate inside the base 2, so that the two sliders 7 threadedly connected to the bidirectional lead screw 6 approach each other relatively. The guide rod 5 plays a stabilizing role and then promotes the movement of the support frame 4, thereby driving the device body 1 at the upper end of the support frame 4 to slowly rise. While the slider 7 moves, the rotating plate 11 at its lower end also rotates, thereby causing the support plate 8 connected to the rotating plate 11 to gradually descend and stably contact the ground. During this process, the universal wheels 9 at the lower end of the base 2 will be disengaged from the ground, improving the construction safety, thus enhancing the stability of the entire device, enabling the steel member to adapt to different installation requirements, and improving the assembly accuracy. When support is not required, the universal wheels 9 can be brought into contact with the ground through reverse operation, facilitating the movement of the entire device.

[0035] Working principle: During use, place the steel member on the upper end of the rotating disk 303. Then start the second motor 311 to drive the rotating shaft 309 to rotate and make the external gear 307 rotate synchronously. At this time, the external part of the gear 307 is inside the first internal gear ring 306 and the two are meshed. When the gear 307 rotates, it will cause the first internal gear ring 306 to drive the chuck 304 to rotate, and then make the two clamping plates 302 at its upper end move towards each other, so that the clamping plates 302 clamp the steel member, and the buffer pad 301 can protect the steel member from damage. Then, rotate the screw 313 to make the external rotating block 312 move inwards and rotate. The rotating block 312 will make the moving frame 310 move downwards inside the device body 1. Since the outside of the second motor 311 is arranged inside the moving frame 310, when the moving frame 310 moves downwards, the second motor 311 will move synchronously, and then the rotating shaft 309 will drive the gear 307 to move synchronously. The inside of the rotating shaft 309 will slide on the outside of the sliding rod 305, and at the same time, the meshing relationship between the gear 307 and the first internal gear ring 306 is gradually released. When the gear 307 moves to the set position, it will complete meshing with the second internal gear ring 308, and then stop rotating the screw 313;

[0036] Secondly, when the steel member is pushed to the installation position, the first motor 10 inside the base 2 is started to drive the bidirectional lead screw 6 to rotate. The rotation of the bidirectional lead screw 6 will cause the two sliders 7 threadedly connected thereto to move towards each other, thereby gradually driving the device main body 1 to move upward by the support frame 4. While the slider 7 moves, the rotating plate 11 will rotate, and then the support plate 8 connected to the rotating plate 11 will move downward and gradually contact the ground, so that the universal wheels 9 at the lower end of the base 2 are gradually disengaged from the ground contact, improving the stability. When the angle of the steel member needs to be adjusted, the second motor 311 is started to rotate the rotating shaft 309 and drive the gear 307 to rotate. Since the gear 307 is engaged with the second internal gear ring 308 at this time, the rotation of the gear 307 will drive the rotating disc 303 to rotate, realizing the angle adjustment of the steel member, thereby improving the assembly efficiency of the steel member.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
