Description

Technical Field

[0001] This utility model relates to the field of highway bridge construction technology, and in particular to a construction support bracket device for highway bridges. Background Technology

[0002] Highway bridge engineering refers to all work related to the planning, design, construction, maintenance, and repair of structures that cross waterways, valleys, and all transportation routes. Highway bridge engineering includes the main bridge structure (i.e., the superstructure and substructure) and the ancillary engineering facilities within the overall bridge structure. During the construction of highway bridges, bracket systems are required to support them.

[0003] A search of Chinese patent "A Support Bracket for Highway Bridge Construction" (publication number CN220813463U) reveals that this patent utilizes a movable seat, a lifting platform, a lifting mechanism, a support plate, a jacking mechanism, and a fixing mechanism. The fixing mechanism secures the device to the support location. The lifting mechanism moves the movable seat, which in turn moves the lifting platform, which in turn moves the support plate, bringing it into contact with the bottom of the bridge structure for support. During long-term support, if further elevation is needed, the jacking mechanism can be used to raise the structure, improving the device's stability and enhancing its practicality. However, the device's support for the bridge is not sufficiently stable when the support plate and lifting platform work together. The telescopic rod and tension spring are prone to swaying during bridge support, hindering stable support and reducing the device's effectiveness.

[0004] Therefore, a construction support bracket device for highway bridges is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a construction support bracket device for highway bridges to solve the above-mentioned problems, thereby improving the inconvenience of providing stable support for bridges.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a construction support bracket device for highway bridges, comprising a base plate, two support rods at the top of the base plate, one support rod being slidably connected to the inner wall of the other support rod, and the other support rod being fixedly connected to the top of the base plate; a support plate being fixedly connected to the top of one of the support rods; and a support mechanism being provided at the bottom of the support plate. The support mechanism includes support frames fixedly connected to both sides of one of the support rods, one end of each support frame being fixedly connected to the bottom of the support plate; two fixed cylinders are hinged to both sides of the bottom of the support plate; a connecting rod is slidably connected to the inner wall of each fixed cylinder; one end of each connecting rod passes through the fixed cylinder and is hinged to the support frame; two compression springs are provided on the inner wall of each fixed cylinder; and one end of the connecting rod is positioned between the two compression springs.

[0007] Preferably, the support mechanism further includes two mounting plates fixedly connected to the outer wall of one of the support rods, and a number of evenly distributed support blocks are fixedly connected to the top of the mounting plates, with the top of the support blocks being fixedly connected to the support plates.

[0008] Preferably, a reinforcing plate is fixedly connected between the bottom end of the mounting plate and one of the support rods, and the reinforcing plate can improve the support strength between the mounting plate and the support block.

[0009] Preferably, a limiting plate is fixedly connected to the top of the support plate. The limiting plate can increase the coefficient of friction between the support plate and the supported object, thereby improving the support effect of the device.

[0010] Preferably, a limiting groove is provided at the top of the limiting plate, which can further improve the supporting effect of the limiting plate.

[0011] Preferably, a lead screw is rotatably connected to the inner wall of the other support rod, and the lead screw is threadedly connected to one of the support rods.

[0012] Preferably, a motor is installed on the inner wall of the base plate, and the output shaft at one end of the motor is fixedly connected to a lead screw.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up a support mechanism, when supporting a highway bridge, one of the support rods can support the bottom sides of the support plate through the support frames on both sides. The fixing cylinder, through two compression springs on its inner wall, cooperates with the connecting rod to improve the connection effect between the support frame and the support plate. The two compression springs can increase the support force of the connecting rod. The fixing cylinder and the connecting rod can provide auxiliary support for the support plate. The mounting plate and the support block cooperate to support and fix the front and rear ends of the support plate. The reinforcing plate can improve the support strength of the mounting plate. The limiting plate and the limiting groove cooperate to increase the friction coefficient between the support plate and the supported object, which can provide stable support for the highway bridge and improve the support effect of the device.

[0015] 2. By setting up a lead screw and a motor, when the support bracket supports the highway bridge, one of the support rods cooperates with the lead screw to move upward and drive the support plate to support the highway bridge. Both support rods are square, which can prevent them from rotating when the lead screw rotates. The motor is a servo motor, which can drive the lead screw to rotate forward and backward and adjust the height of the support rods, so as to quickly support the highway bridge.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In practical implementation: such as Figure 1-4As shown, a construction support bracket device for highway bridges includes a base plate 1. Two support rods 2 are mounted on the top of the base plate 1. One support rod 2 is slidably connected to the inner wall of the other support rod 2, and the other support rod 2 is fixedly connected to the top of the base plate 1. A support plate 3 is fixedly connected to the top of one of the support rods 2, and a support mechanism 4 is mounted on the bottom of the support plate 3. The support mechanism 4 includes a support frame 401 fixedly connected to both sides of one of the support rods 2. One end of the support frame 401 is fixedly connected to the bottom of the support plate 3. Two fixed cylinders 402 are hinged to both sides of the bottom of the support plate 3. A connecting rod 403 is slidably connected to the inner wall of the fixed cylinder 402. One end of the connecting rod 403 passes through the fixed cylinder 402 and is hinged to the support frame 401. Two compression springs 404 are mounted on the inner wall of the fixed cylinder 402, and one end of the connecting rod 403 is positioned between the two compression springs 404.

[0023] like Figure 2 and Figure 3 As shown, the support mechanism 4 also includes two mounting plates 405 fixedly connected to the outer wall of one of the support rods 2. Several evenly distributed support blocks 406 are fixedly connected to the top of the mounting plate 405. The top of the support blocks 406 is fixedly connected to the support plate 3. A reinforcing plate 407 is fixedly connected between the bottom of the mounting plate 405 and one of the support rods 2. A limiting plate 408 is fixedly connected to the top of the support plate 3. A limiting groove 409 is formed at the top of the limiting plate 408. When the two support frames 401 support the support plate 3, the fixed... The cylinder 402 and the connecting rod 403 are respectively connected to the bottom end of the support plate 3 and the support frame 401. The connecting rod 403 cooperates with two compression springs 404 to provide auxiliary support for the support plate 3 and the support frame 401, thereby improving the stability of the support plate 3. The mounting plate 405, through the reinforcing plate 407, allows multiple support blocks 406 to support the front and rear ends of the support plate 3. The support plate 3, through the limiting plate 408 and the limiting groove 409, limits the position of the highway bridge, thereby providing stable support for the highway bridge.

[0024] like Figure 4 As shown, a lead screw 410 is rotatably connected to the inner wall of another support rod 2, and the lead screw 410 is threadedly connected to one of the support rods 2. A motor 411 is installed on the inner wall of the base plate 1, and the output shaft of one end of the motor 411 is fixedly connected to the lead screw 410. The lead screw 410, through the threaded connection between the motor 411 and one of the support rods 2, can adjust the position of the two support rods 2, which can drive the support plate 3 to quickly support the highway bridge and improve the effectiveness of the device.

[0025] In use, the bracket is moved to a suitable position and fixed by two positioning pins on both sides of the base plate 1. The PLC controller outside the bracket can drive the motor 411 to rotate the lead screw 410. The lead screw 410 is threadedly connected to one of the support rods 2, which drives the support plate 3 to move upward and contact the bottom end of the supported object. It is supported by the limiting plate 408 and the limiting groove 409. The support brackets 401 on both sides of one of the support rods 2 can support the two sides of the support plate 3. One of the support rods 2 can support the front and rear ends of the support plate 3 by cooperating with the support block 406 through two mounting plates 405.
