Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a main crossbeam tooling structure. Background Technology

[0002] The main beam is an important component of a building structure, especially in bridges, building frames, greenhouses and other structures, where it plays a key role. The main beam can bear loads from above or the sides, such as vehicle loads on bridges and floor loads on building frames. It firmly connects the various main beams (or main load-bearing components) together to form a stable whole structure, effectively transferring the load to the foundation or other load-bearing components, and ensuring the stability and safety of the entire structure.

[0003] The main crossbeam fixture is a special clamp or device used in the processing, positioning, welding and other processes of the main crossbeam. Before assembling the main crossbeam, both ends of the crossbeam need to be ground to make the crossbeam more compact in application. The existing main crossbeams are connected by using a crane to pull or using a top block to lift them. During operation, the operator needs to stand at a high position, which poses a safety hazard. Therefore, this utility model proposes a main crossbeam fixture structure to solve the above problems. Utility Model Content

[0004] To address the aforementioned issues, this utility model proposes a main crossbeam tooling structure to solve the problem that in the prior art, the main crossbeam is connected by using a crane to pull it or by using a top block to push it up, which requires the operator to stand at a high position during operation, thus posing a safety hazard.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a main crossbeam tooling structure, including a base plate, an outer side plate and an inner side plate, the outer side plates are symmetrically provided on both sides of the base plate, the inner side plate is fixedly connected to one side of the outer side plate through a reinforcing plate, a clamping mechanism is provided in the middle of the inner side plate, and a guide mechanism is symmetrically provided on both sides of the base plate.

[0006] A further improvement is made in that: the clamping mechanism includes a sliding block, a clamping block, a slide rail, and a bolt; an L-shaped slide rail is symmetrically fixedly connected to the middle of the inner side plate; a sliding block is slidably connected to the top of the slide rail; a clamping block is slidably connected to the bottom of the slide rail; a bolt is rotatably connected to the bottom of the slide rail; and the outer wall of the bolt is threadedly connected to the inner wall of the sliding block.

[0007] A further improvement is that: both the sliding block and the clamping block have inclined surfaces on their adjacent sides, and the angles of the two inclined surfaces match each other, so that the sliding block and the clamping block are connected to each other through the inclined surfaces.

[0008] A further improvement is that the outer side plate has a double-layer structure, and the inner side plate has symmetrical insertion holes, with pins inserted into the insertion holes.

[0009] A further improvement is that the guiding mechanism includes a rotating arm and a roller. The rotating arms are symmetrically hinged to both sides of the base plate via nylon shafts. A roller is hinged to one end of the rotating arm via a nylon shaft. The top of the roller is at the same height as the two sides of the base plate.

[0010] A further improvement is made in that: a rectangular groove is provided inside the base plate, a pressure plate is provided inside the rectangular groove, positioning blocks are symmetrically provided on the top of the pressure plate, and a locking mechanism is provided between the pressure plate and the rectangular groove.

[0011] A further improvement is that the engaging mechanism includes a slot and a strip, the bottom of the pressure plate is symmetrically fixedly connected with the strip, the rectangular groove is symmetrically provided with slots inside, and the outer wall of the strip engages with the inside of the slot.

[0012] The beneficial effects of this utility model are as follows: After placing the two main crossbeams on the top of the base plate, insert a hex wrench into the top of the bolt, and rotate the sliding block by turning the hex wrench. Because the bolt and the sliding block are threadedly matched, and the slide rail restricts the movement trajectory of the sliding block, the bolt can drive the sliding block to move up and down reciprocally when rotating in both directions. When the sliding block moves downward, it moves towards one side of the main crossbeam by squeezing the clamping block with the inclined surface, so that the clamping block clamps the outer side of the main crossbeam, thereby fixing one end of the two main crossbeams to the base plate. The two main crossbeams are pre-connected at one end, and then the two main crossbeams are erected at a high position. In this way, the structure is more stable when connecting the two main crossbeams, reducing safety hazards. Attached Figure Description

Detailed Implementation

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a main crossbeam fixture structure, including a base plate 1, an outer side plate 2, and an inner side plate 3. The outer side plates 2 are symmetrically arranged on both sides of the base plate 1. The inner side plate 3 is fixedly connected to one side of the outer side plate 2 through a reinforcing plate 4. A clamping mechanism is provided in the middle of the inner side plate 3. Guide mechanisms are symmetrically arranged on both sides of the base plate 1. The guide mechanisms on both sides of the base plate 1 smoothly place one end of the two main crossbeams on the top of the base plate 1. Then, the clamping mechanism clamps the two sides of the main crossbeams to completely fix the two main crossbeams on the base plate 1. The two main crossbeams are pre-connected at one end and then erected at a high position. This makes the structure more stable when connecting the two main crossbeams and reduces safety hazards.

[0020] The outer side plate 2 has a double-layer structure. The inner side plate 2 has symmetrical insertion holes. A pin 15 is inserted into the insertion hole. The two outer side plates 2 are brought together and the pin 15 is inserted into the insertion hole and passes through the inner side plate 2 to initially fix the two outer side plates 2 together. Then, the bottom of the two sets of outer side plates 2 are attached to the two sides of the base plate 1 to facilitate welding the outer side plates 2 and the base plate 1 together.

[0021] The guiding mechanism includes a rotating arm 13 and rollers 14. The rotating arms 13 are symmetrically hinged to both sides of the base plate 1 via nylon shafts. One end of the rotating arm 13 is hinged to a roller 14 via a nylon shaft. The top of the roller 14 is at the same height as the two sides of the base plate 1. Rotating the rotating arm 13 outward can adjust the distance between the two rollers 14 so that it matches the width of the main crossbeam. Rotating the roller 14 along the hinge point on one side of the roller 14 makes the roller 14 parallel to the width direction of the base plate 1. The nylon shaft has high friction and can be locked in position after rotation. The roller 14 can reduce the friction between the rotating arm 13 and the main crossbeam, making it easier for the main crossbeam to enter the top of the base plate 1.

[0022] The clamping mechanism includes a sliding block 5, a clamping block 6, a slide rail 7, and a bolt 8. An L-shaped slide rail 7 is symmetrically fixedly connected to the middle of the inner side plate 3. The top end of the slide rail 7 is slidably connected to the sliding block 5, and the bottom end of the slide rail 7 is slidably connected to the clamping block 6. The bottom of the slide rail 7 is rotatably connected to the bolt 8. The outer wall of the bolt 8 is threadedly connected to the inner wall of the sliding block 5. The sliding block 5 and the clamping block 6 are each provided with an inclined surface on their adjacent sides. The angles of the two inclined surfaces match each other, and the sliding block 5 and the clamping block 6 are connected to each other by the inclined surfaces.

[0023] After placing the two main crossbeams on top of the base plate 1, insert a hex wrench into the top of the bolt 8 and turn the sliding block 5 by tightening the hex wrench. Because the bolt 8 and the sliding block 5 are threadedly engaged, and the slide rail 7 restricts the movement trajectory of the sliding block 5, the bolt 8 can drive the sliding block 5 to move up and down reciprocally when it rotates in both directions. When the sliding block 5 moves downward, it moves towards one side of the main crossbeam by pressing the clamping block 6 with the inclined surface, so that the clamping block 6 clamps the outer side of the main crossbeam to fix one end of the two main crossbeams to the base plate 1. Or, when the sliding block 5 moves upward, the sliding block 5 no longer presses the clamping block 6 with the inclined surface, so that there is a gap between the clamping block 6 and the main crossbeam, which makes it convenient to remove the entire fixture from the outside after the two main crossbeams are fixed together by the connecting bolts.

[0024] The rectangular groove inside the base plate 1 has a pressure plate 10 inside. The top of the pressure plate 10 is symmetrically provided with positioning blocks 11. The main crossbeam is mostly designed as an I-beam structure. The positioning blocks 11 can directly support the cross plate in the middle of the main crossbeam, making the main crossbeam more stable on the base plate 1.

[0025] A locking mechanism is provided between the pressure plate 10 and the rectangular groove. The locking mechanism includes a locking groove 9 and a locking strip 12. The bottom of the pressure plate 10 is symmetrically fixedly connected with the locking strip 12. The rectangular groove is symmetrically provided with the locking groove 9. The outer wall of the locking strip 12 is locked to the inside of the locking groove 9. When the main crossbeam enters the top of the base plate 1, it rubs against the top of the base plate 1, causing scratches and increasing its roughness. Over time, the wear between the base plate 1 and the new main crossbeam will be more severe. At this time, the pressure plate 10 can be pulled out from the top of the base plate 1. After aligning the locking strip 12 at the bottom of the new pressure plate 10 with the locking groove 9, the locking strip 12 is inserted into the inside of the locking groove 9 to fix the new pressure plate 10 to the top of the base plate 1.

[0026] The main crossbeam fixture structure involves placing two main crossbeams on top of the base plate 1, inserting a hex wrench into the top of the bolt 8, and turning the sliding block 5 by tightening the hex wrench. Because the bolt 8 and the sliding block 5 are threadedly engaged, and the slide rail 7 restricts the movement trajectory of the sliding block 5, the bolt 8 can drive the sliding block 5 to move up and down reciprocally when it rotates in both directions. When the sliding block 5 moves downward, it moves towards one side of the main crossbeam by pressing the clamping block 6 with the inclined surface, so that the clamping block 6 clamps the outer side of the main crossbeam, thereby fixing one end of the two main crossbeams to the base plate 1. The two main crossbeams are pre-connected at one end, and then the two main crossbeams are erected at a high position. This makes the structure more stable when connecting the two main crossbeams and reduces safety hazards.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
