Description

Technical Field

[0001] This utility model belongs to the technical field of steel box girder production equipment, and in particular relates to a partition plate installation clamp for steel box girder fabrication. Background Technology

[0002] Steel box girders are a type of steel structure widely used in the construction of bridges and overpasses. A steel box girder is mainly composed of five parts: top plate, bottom plate, web plate, duct plate, and diaphragm plate. The web plate is located between the top plate and the bottom plate, the diaphragm plate is located on both sides of the top plate and the bottom plate, and the duct plate is used for the connection between the ends of the top plate and the bottom plate.

[0003] Chinese patent application CN216405135U discloses a diaphragm clamp for assembling diaphragms of bridge steel box girders. The clamp includes: a linear guide rail disposed on the side of the bottom plate of the bridge steel box girder supported by a bottom plate support block, extending along the length of the bottom plate; a moving unit cooperating with the linear guide rail and slidable along it; and a diaphragm clamping assembly connected to the moving unit and moving synchronously with it, used to clamp and fix the sides of several assembled diaphragms one by one. This clamping and fixing ensures that the relative position between the diaphragm and the bottom plate remains unchanged, thereby guaranteeing the accuracy of subsequent welding and assembly.

[0004] The aforementioned diaphragm clamp for assembling bridge steel box girder diaphragms includes linear guide rails. These rails support the bottom of the diaphragm while allowing it to slide within them, thus enabling adjustment of its horizontal installation position. However, the spacing between the linear guide rails is not adjustable. To ensure the stability of the diaphragm's movement, the rail spacing must precisely match the diaphragm's thickness, resulting in this type of linear guide rail being suitable only for specific diaphragm models. Furthermore, it also includes a diaphragm support assembly, comprising a mounting bracket and a mounting plate... The gripper drive mechanism on the mounting frame has its end connected to the partition via grippers. The gripper drive mechanism controls the opening and closing of the grippers, thereby achieving a clamping and releasing effect on the side of the partition. Then, with the cooperation of the pushing mechanism, the gripper drive mechanism is pushed, carrying the grippers and clamping the partition for movement. Because the grippers are highly sensitive grasping devices, when pushing the partition, due to the partition's significant weight and the grippers' high sensitivity, the pressure on the grippers during movement is also substantial, easily causing damage. Therefore, we provide a partition mounting fixture for steel box girder fabrication to solve the above-mentioned problems. Utility Model Content

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model comprises a clamping plate 1, a clamping plate 2, a hydraulic cylinder 1, and a receiving assembly. The clamping plate 1 has a side insert plate at its end, and the clamping plate 2 has a grooved plate at its end. When clamping plate 1 and clamping plate 2 are aligned, the side insert plate engages with the grooved plate. Clamping plate 1 and clamping plate 2 also have corresponding holes on their side walls. The receiving assembly includes bearing sleeves embedded in the bearing sleeves of the bearing sleeves. Clamping plate 1 and clamping plate 2 are connected to a support via these bearing sleeves. The rod is connected at both ends, and a rotating sleeve is fitted at the middle of the support rod. A spring is fitted to the side of the rotating sleeve and the outer wall of the support rod, and the rotating sleeve is connected to the outer wall of the bearing sleeve through the spring. Fixed sleeves are also fixedly installed at both ends of the support rod. A hydraulic cylinder is installed at the ends of clamping plates one and two. Fixed seats are installed at both ends of hydraulic cylinder one, and hydraulic cylinder one is connected to the outer walls of clamping plates one and two respectively through the fixed seats at both ends. In use, hydraulic cylinder one operates, and its... When the hydraulic cylinder extends, it pushes clamping plates one and two away from each other, increasing the distance between them. This allows for clamping of the thicker steel box girder's partition. When hydraulic cylinder one extends to its maximum length, the side insert plate will not disengage from the grooved plate, thus stabilizing clamping plates one and two. Conversely, when hydraulic cylinder one retracts, clamping plates one and two move closer together, decreasing the distance between them. This allows for clamping of the thinner steel box girder's partition. When the distance between clamping plates one and two changes, the bearing sleeves on clamping plates one and two move accordingly. The rotating sleeve, due to the presence of springs on both sides, remains in the middle position of the support rod. Simultaneously, due to the presence of the fixed sleeve, the bearing sleeve will not disengage from the support rod. Then, the bottom sidewall of the partition is placed on the rotating sleeve. As the partition moves between clamping plates one and two, the rotating sleeve rotates on the support rod, thus assisting in the movement of the partition.

[0018] 2. This utility model features a top plate and a pushing assembly. The upper ends of clamping plates one and two are equally spaced, with the top plate and clamping plate one or two forming an integral structure. A pushing assembly is installed within the top plate. A top groove is formed in the top plate, and side grooves are formed on the sides of the top groove and on the outer wall of the top plate. The pushing assembly includes a pushing wheel set in the top groove and a mounting plate fixedly set in the side groove. An axle is inserted into the center of the pushing wheel, and the axle is rotatably connected to the upper and lower side walls of the top groove via a bushing. A mounting bracket is fixedly set on the mounting plate, and a hydraulic cylinder two is fixedly set within the mounting bracket. The telescopic end of the hydraulic cylinder two faces the pushing wheel. The pushing wheel has a sawtooth structure. In operation, once clamping plates one and two clamp the partition, hydraulic cylinder two in the push assembly operates, intermittently extending and retracting. When extending, the end of hydraulic cylinder two contacts the push wheel on the outer side of the top plate, abutting against the buffer pad in the groove of the push wheel. At this time, the push wheel rotates as hydraulic cylinder two continues to extend. Meanwhile, the other end of the push wheel abuts against the outer wall of the partition, supporting the partition in a vertical position. It also allows the partition to move between clamping plates one and two while the push wheel rotates. The repeated extension and retraction of hydraulic cylinder two ensures that the push wheel continuously pushes the partition to move. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figure 1-3 This utility model is a partition installation fixture for steel box girder fabrication, including a first clamp 1, a second clamp 2, a first hydraulic cylinder 3, and a supporting component 4. The distance between the first clamp 1 and the second clamp 2 can be adjusted by the first hydraulic cylinder 3 to adapt to partitions of different thicknesses, and the supporting component 4 can assist in supporting the partition.

[0029] Specifically, side insert plates 101 and grooved plates 201 are respectively provided on both sides of clamp plate 1 and clamp plate 2. The side insert plates 101 and grooved plates 201 are inserted into each other. Hydraulic cylinder 3 is also provided on the outer side of the side insert plates 101 and grooved plates 201. Fixing seats 301 are fixedly installed on both ends of hydraulic cylinder 3, and hydraulic cylinder 3 is connected to the outer wall of the end of clamp plate 1 and clamp plate 2 through fixing seats 301.

[0030] Furthermore, clamping plate 1 and clamping plate 2 are respectively provided with plate hole 102 and plate hole 202, which are arranged opposite to each other. The receiving component 4 includes a bearing sleeve 404 embedded in plate hole 102 and plate hole 202, and plate hole 102 and plate hole 202 are rotatably connected to both ends of support rod 401 through bearing sleeve 404. A rotating sleeve 402 is also sleeved on the middle position of support rod 401. A spring 403 is sleeved on the outer side of rotating sleeve 402 and support rod 401. Rotating sleeve 402 abuts against the outer wall of bearing sleeve 404 through spring 403. A fixing sleeve 405 is fixedly provided on the outer side of bearing sleeve 404 and the outer end of support rod 401.

[0031] The operation process of this embodiment is as follows: During use, hydraulic cylinder 3 extends, pushing clamping plates 1 and 2 away from each other, increasing the distance between them. This allows for clamping of the thicker steel box girder's partitions. Even when hydraulic cylinder 3 extends to its maximum length, the side insert plate 101 will not detach from the groove plate 201, thus stabilizing clamping plates 1 and 2. Conversely, when hydraulic cylinder 3 retracts, clamping plates 1 and 2 move closer together, decreasing the distance between them, allowing for clamping of the thinner steel box girder's partitions. The clamping mechanism is as follows: when the distance between clamp 1 and clamp 2 changes, the bearing sleeves 404 on clamp 1 and clamp 2 will move accordingly. The rotating sleeve 402, due to the presence of springs 403 on both sides, is always in the middle position of the support rod 401. At the same time, due to the presence of the fixed sleeve 405, the bearing sleeve 404 will not detach from the support rod 401. Then, the bottom side wall of the partition is placed on the rotating sleeve 402. When the partition moves between clamp 1 and clamp 2, the rotating sleeve 402 will rotate on the support rod 401, thereby achieving the effect of assisting the partition to move.

[0032] Example 2

[0033] Please see Figure 4 Based on embodiment 1, a top plate 5 and a pushing component 6 are also provided. The pushing component 6 can not only support the partition, but also push the partition to move between clamp 1 and clamp 2.

[0034] Specifically, both the upper ends of the clamping plate 1 and the clamping plate 2 are integrally provided with a top plate 5. There are multiple top plates 5, and the multiple top plates 5 are equally spaced. A top groove 501 is opened on the top plate 5, and a side groove 502 is opened on the side of the top groove 501 and on the outer wall of the top plate 5.

[0035] Furthermore, the pushing assembly 6 includes a pushing wheel 601 disposed in the top groove 501 and a mounting plate 603 disposed in the side groove 502. A wheel axle 602 is also inserted on the central axis of the pushing wheel 601, and the upper and lower ends of the wheel axle 602 are rotatably connected to the upper and lower side walls of the top groove 501 through bushings 602a. The pushing wheel 601 is configured with a sawtooth structure, and a buffer pad 601a is also embedded in the inner wall of the sawtooth groove of the pushing wheel 601. A mounting bracket 604 is also fixedly disposed on the mounting plate 603, and a second hydraulic cylinder 605 is installed in the mounting bracket 604. The telescopic end of the second hydraulic cylinder 605 is oriented towards the sawtooth groove of the pushing wheel 601.

[0036] The operation process of this embodiment is as follows: When in use, after clamping plate 1 and clamping plate 2 form a clamping and limiting effect on the partition, hydraulic cylinder 605 in the push assembly 6 is activated, and it performs intermittent extension and retraction actions. When it extends, the end of hydraulic cylinder 605 contacts the push wheel 601 on the outer side of the top plate 5, that is, it abuts against the buffer pad 601a in the groove of the push wheel 601. At this time, the push wheel 601 is subjected to force and rotates as hydraulic cylinder 605 continues to extend. At the same time, the other end of the push wheel 601 abuts against the outer wall of the partition, which supports the partition to a vertical state. It can also push the partition to move between clamping plate 1 and clamping plate 2 while the push wheel 601 rotates. The hydraulic cylinder 605 extends and retracts in this way, which can make the push wheel 601 continuously push the partition to move.
