Description

Technical Field

[0001] This utility model relates to the field of steel structure docking technology, and in particular to a steel structure docking device for steel structure construction. Background Technology

[0002] In the application of steel structures, it is often necessary to weld adjacent steel structures together to form a stable whole. During welding, the steel structure needs to be secured first, requiring the use of clamping devices to prevent shaking during welding.

[0003] A search revealed that Chinese Patent Publication No. CN221891280U discloses a steel structure docking device for steel structure construction, including a No. 1 steel structure, a No. 2 steel structure set on the right side of the No. 1 steel structure, clamping plates set on the front and rear sides of the No. 1 and No. 2 steel structures, a rectangular block fixedly installed at the lower end of the clamping plate, and a bidirectional electric push rod fixedly connected between the rectangular blocks on the front and rear sides.

[0004] While the above solution reduces the workload of workers adjusting the position of the steel structure, in actual use, the method of clamping the steel structure by moving the front and rear clamping plates simultaneously with the bidirectional electric actuator can easily lead to misalignment of the two steel structures when they are joined due to slight differences in the installation of the two structures. This makes it inconvenient to make fine adjustments and affects the welding effect.

[0005] Therefore, there is an urgent need to provide a steel structure docking device for steel structure construction to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology, which uses only bidirectional electric actuators to drive the front and rear clamping plates to move simultaneously to clamp the steel structure in actual use. Due to the slight differences in the installation of the two structures, the two steel structures are prone to misalignment when they are joined, making it inconvenient to make fine adjustments and affecting the welding effect. This utility model provides a steel structure joining device for steel structure construction.

[0007] To solve the above-mentioned technical problems, the present invention provides a steel structure docking device for steel structure construction, including a base, and further comprising:

[0008] A support plate is provided on the top of the base;

[0009] L-shaped plate, each of the support plates has an L-shaped plate movably provided on its side;

[0010] An adjustment component is disposed on the top of the L-shaped plate;

[0011] The adjustment assembly includes a displacement seat disposed on the top of the L-shaped plate, a moving unit disposed between the displacement seat and the L-shaped plate, a lifting plate disposed on the top of the displacement seat, and a lifting unit disposed at the bottom of the lifting plate.

[0012] A connecting unit is provided between the two L-shaped plates.

[0013] The present invention is further configured such that: a rotating shaft is installed on the side of the L-shaped plate, the rotating shaft is movably connected to the side wall of the support plate, and a rotating component is provided on the side of the rotating shaft.

[0014] The present invention is further configured such that: a groove is provided on the top surface of the L-shaped plate, and the displacement seat is movably disposed inside the groove;

[0015] The moving unit includes a threaded hole located at the bottom of the side of the displacement seat and a threaded rod movably disposed inside the threaded hole. A guide rod is disposed opposite to the outside of the threaded rod, and a guide hole adapted to the longitudinal cross-sectional dimensions of the guide rod is provided on the side of the displacement seat.

[0016] The present invention is further configured such that: a groove is provided on the inner wall of the displacement seat, and the lifting plate is movably disposed inside the groove;

[0017] The lifting unit includes a bidirectional lead screw movably connected to the inner wall of the displacement seat, a sliding sleeve disposed opposite to the outside of the bidirectional lead screw, and a movable rod movably connected between the sliding sleeve and the lifting plate.

[0018] The present invention is further configured such that: the connecting unit includes a fixed shell fixedly connected to the bottom of one of the L-shaped plates, one end of an extrusion member fixedly connected to the inner wall of the fixed shell, and one end of a limiting frame fixedly connected to the other end of the extrusion member; a limiting frame is provided on the outer side of the other end of the limiting frame; and the limiting frame is fixedly connected to the bottom of the other L-shaped plate.

[0019] The present invention is further configured such that: the adjustment assembly also includes a clamping unit disposed on the top of the lifting plate;

[0020] The clamping unit includes a first clamping plate and a second clamping plate disposed opposite each other on the top of the lifting plate, and a pusher disposed on the side of the first clamping plate or the second clamping plate.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This utility model uses an adjustment component to place two steel structures to be joined on top of two lifting plates, with one end of each steel structure abutting against each other. A corresponding pusher pushes the first and second clamping plates to move relative to each other, clamping the steel structures. Rotating the threaded rod causes the displacement seat to slide along the length of the guide rod under the action of the threaded pair. The sliding of the displacement seat adjusts the lateral position of the lifting plate. Rotating the double-acting screw causes two sliding sleeves to move relative to each other along the outer side of the double-acting screw under the action of the threaded pair. This, in conjunction with the movable rod, raises or lowers the lifting plate, adjusting its height and fine-tuning the lateral and longitudinal positions of the steel structures. This ensures precise alignment of the two steel structures for subsequent welding work.

[0023] 2. This utility model uses a connecting unit and a rotating component to push a limiting frame with one end of the pressing component to engage with the limiting frame through the elastic pressing action of the pressing component, thereby fixing the two L-shaped plates together. Then, the rotating component drives the rotating shaft to rotate, thereby rotating the two L-shaped plates and adjusting the welding position of the two steel structures in real time for welding.

The moving unit 42 is used to adjust the horizontal position of the lifting plate 43, and the lifting unit 44 is used to adjust the vertical position of the lifting plate 43.

[0035] A connecting unit 45 is provided between the two L-shaped plates 3.

[0036] The L-shaped plate 3 has a rotating shaft 31 installed on its side. The rotating shaft 31 is movably connected to the side wall of the support plate 2, and the rotating shaft 31 has a rotating component 46 on its side. Preferably, the rotating component 46 is a rotary cylinder. The rotating shaft 31 is rotatably connected to the side wall of the support plate 2.

[0037] Among them, the top surface of the L-shaped plate 3 is provided with a groove, and the displacement seat 41 is movably disposed inside the groove;

[0038] The moving unit 42 includes a threaded hole provided at the bottom side of the displacement seat 41, a threaded rod 421 movably provided inside the threaded hole, a guide rod 422 provided on the outer side of the threaded rod 421, a guide hole provided on the side of the displacement seat 41 that matches the longitudinal cross-sectional dimensions of the guide rod 422, the threaded rod 421 being rotatably connected to the side wall of the L-shaped plate 3, and the guide rod 422 being welded to the side wall of the groove of the L-shaped plate 3.

[0039] The inner wall of the displacement seat 41 is provided with a sliding groove, and the lifting plate 43 is movably disposed inside the sliding groove.

[0040] The lifting unit 44 includes a bidirectional lead screw 441 movably connected to the inner wall of the displacement seat 41, a sliding sleeve 442 disposed opposite to the outside of the bidirectional lead screw 441, and a movable rod 443 movably connected between the sliding sleeve 442 and the lifting plate 43.

[0041] The connecting unit 45 includes a fixed shell 451 fixedly connected to the bottom of one of the L-shaped plates 3, one end of an extrusion member 452 fixedly connected to the inner wall of the fixed shell 451, and one end of a limiting frame 453 fixedly connected to the other end of the extrusion member 452. A limiting frame 454 is provided on the outer side of the other end of the limiting frame 453. The limiting frame 454 is fixedly connected to the bottom of the other L-shaped plate 3.

[0044] In use, the two steel structures to be joined are first placed on top of two lifting plates 43, with one end of each steel structure abutting against each other. The opposing pushers 473 then drive the first clamping plate 471 and the second clamping plate 472 to move relative to each other, clamping the steel structures. Next, by rotating the threaded rod 421, the displacement seat 41 slides along the length of the guide rod 422 under the action of the threaded pair.

Then, by rotating the bidirectional screw 441, the two sliding sleeves 442 move relative to each other along the outer side of the bidirectional screw 441 under the action of the threaded pair. This causes the lifting plate 43 to rise or fall via the movable rod 443, adjusting its height and thus the lateral and longitudinal positions of the steel structures. This ensures precise alignment of the two steel structures for subsequent welding work.

[0045] During welding, the elastic pressing action of the extrusion member 452 pushes the limiting frame 453 so that one end of it engages with the limiting frame 454, thereby fixing the two L-shaped plates 3 in place. Then, the rotating member 46 drives the rotating shaft 31 to rotate, thereby rotating the two L-shaped plates 3 and adjusting the welding position of the two steel structures in real time for welding.
