Description

Technical Field

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

[0002] Highway bridges are artificial structures built across natural or man-made obstacles in highway transportation networks. They are an important part of highway engineering, ensuring the continuity, safety, and efficiency of highway traffic, while also meeting requirements for structural strength, durability, and economy. Construction support brackets for highway bridges are specialized engineering equipment used during bridge construction to provide temporary support, bear structural loads, and ensure construction safety. They provide a stable support platform for bridge components, ensuring the mechanical balance and deformation control of the structure during the construction phase.

[0003] As disclosed in Chinese Patent CN213836329U, a widely applicable support bracket for highway bridge construction uses a drive motor to rotate a threaded rod. The rotation of the adjusting rod is limited by the engagement of the threaded rod with a threaded blind hole and the guide block and guide rod. When the threaded rod rotates, the adjusting rod moves up and down, thus adjusting the height of the four corners of the base. This allows for placement on surfaces of varying heights. The combined use of the lead screw, positioning rod, positioning port, limiting block, and rotating handwheel effectively secures the mounting plate and sleeve, preventing the mounting plate and sleeve from slipping due to hydraulic cylinder retraction caused by prolonged support. This improves the stability and practicality of the support bracket.

[0004] While this structure can support highway bridges, its fixed base support range results in poor stability. Therefore, we propose a construction support bracket device for highway bridges that can expand the support base to improve support stability. Utility Model Content

[0005] The purpose of this utility model is to provide a construction support bracket device for highway bridges to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a construction support bracket device for highway bridges, comprising a vehicle body, a lifting bracket mechanism fixedly installed on the top surface of the vehicle body, a control panel fixedly installed on the side wall of the vehicle body, and a processing component disposed outside the lifting bracket mechanism, the processing component including a support component disposed outside the vehicle body, and a buffer component disposed above the support component.

[0007] Preferably, the support assembly includes a fixing plate fixedly installed on the outer wall of the vehicle body, a sleeve hinged to the end of the fixing plate, a slide rod slidably disposed inside the sleeve, a collar fixedly installed at the end of the slide rod, a screw sleeved inside the collar, a chassis rotatably connected to the end of the screw, a positioning bolt sleeved inside the sleeve, a first magnetic block fixedly installed on the side wall of the sleeve, and a second magnetic block disposed on the side of the first magnetic block away from the sleeve.

[0008] Preferably, the buffer assembly includes a base plate fixedly installed at one end of the lifting bracket mechanism away from the vehicle body, a sliding column slidably disposed inside the base plate, a spring sleeved on the outer wall of the sliding column, a support plate fixedly installed at the end of the sliding column, and a damper fixedly installed at the bottom of the support plate.

[0009] Preferably, the end of the positioning bolt near the sleeve is made of rubber, and the outer wall of the positioning bolt is threaded into the inside of the sleeve. Under the pressure and restriction of the positioning bolt, the sliding rod can be prevented from sliding inside the sleeve.

[0010] Preferably, the outer wall of the second magnetic block is fixedly installed on the outer wall of the vehicle body, and the first magnetic block and the second magnetic block are magnetically attracted to each other. Under the restriction of magnetic attraction, the sleeve can be prevented from rotating during the movement of the vehicle body.

[0011] Preferably, the damper is fixedly installed on the top surface of the base plate at the end away from the support plate, one end of the spring is fixedly installed on the top surface of the base plate, and the end of the spring away from the base plate is fixedly installed on the bottom of the support plate. With the cooperation of the spring and the damper, the deformed highway bridge can be buffered and supported, avoiding damage to the lifting bracket mechanism by forced pressing.

[0012] Preferably, there are four sliding columns, divided into two groups, symmetrically distributed around the center line of the bottom of the support plate, so that the support plate can slide stably up and down under the constraint of the sliding columns.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The construction support bracket device for highway bridges consists of a support assembly. During highway bridge construction, it requires support. The vehicle body is moved to the desired position, and the lifting bracket mechanism is activated. The support is provided to the highway bridge via a buffer assembly. Due to the small size of the vehicle body base, the vehicle body's support range needs to be expanded to improve stability. At this point, the sleeve is rotated, and the positioning bolt is rotated, so that its end no longer contacts the outer wall of the sliding rod. The sliding rod is pulled, extending the support range. The screw is rotated, pushing the chassis towards the ground. After the sliding rod is fully extended, the positioning bolt is rotated, causing it to move into the sleeve and press against the outer wall of the sliding rod, preventing it from sliding inside the sleeve. The four sets of unfolded sleeves and sliding rods can expand the support range at the bottom of the vehicle body, improving the stability of the lifting bracket mechanism and buffer assembly for supporting the highway bridge. Under the magnetic attraction of the first and second magnetic blocks, the retracted sleeve can be fixed, preventing the sleeve from rotating around the hinge point with the fixed plate as the center of rotation during vehicle movement. This structure expands the vehicle body's support range, improving the stability of the highway bridge support.

[0015] 2. The construction support bracket device used for this highway bridge consists of a buffer component. When the lifting bracket mechanism pushes the buffer component upward as a whole, it supports the highway bridge. During the support process, the highway bridge will be affected by factors such as load, temperature changes, and concrete shrinkage during construction, resulting in deformation. If the buffer component does not provide buffering, it will be squeezed, causing damage to the lifting bracket mechanism. The purpose of the buffering measures is to absorb these deformation energies and prevent the lifting bracket mechanism from overloading. Therefore, the buffer component needs to have a buffering space. The highway bridge squeezes the support plate, causing the sliding column fixedly installed at the bottom of the support plate to slide inside the base plate and compress the spring sleeved on the outer wall of the sliding column. The damper buffers the swaying force generated by the spring, so that the buffer component has a buffering function. Attached Figure Description

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] Example 1: A preferred embodiment of the construction support bracket device for highway bridges provided by this utility model. Figures 1 to 6 As shown: A construction support bracket device for highway bridges, including a vehicle body 1;

[0025] A lifting bracket mechanism 2 is fixedly installed on the top surface of the vehicle body 1;

[0026] A control panel 3 is fixedly installed on the side wall of the vehicle body 1;

[0027] The processing component 4 is located outside the lifting bracket mechanism 2. The processing component 4 includes a support component 41 located outside the vehicle body 1. The support component 41 includes a fixing plate 411 fixedly installed on the outer wall of the vehicle body 1. A sleeve 412 is hinged to the end of the fixing plate 411. A slide rod 413 is slidably installed inside the sleeve 412. A collar 414 is fixedly installed at the end of the slide rod 413. A screw 415 is sleeved inside the collar 414. A chassis 416 is rotatably connected to the end of the screw 415. A positioning bolt 417 is sleeved inside the sleeve 412. A first magnetic block 418 is fixedly installed on the side wall of the sleeve 412. A second magnetic block 419 is provided on the side of the first magnetic block 418 away from the sleeve 412.

[0028] In this embodiment, when the highway bridge is under construction, it needs to be supported. The vehicle body 1 is moved to the required position, and the lifting bracket mechanism 2 is activated. The highway bridge is supported by the buffer assembly 42. Since the base of the vehicle body 1 is small, the range of the vehicle body 1 needs to be expanded to improve the support stability. At this time, the sleeve 412 is rotated, and the positioning bolt 417 is rotated. Its end is no longer in contact with the outer wall of the slide rod 413. The slide rod 413 is pulled to extend the support range. The screw 415 is rotated to push the chassis 416 towards the ground. After the slide rod 413 is extended, the positioning bolt 417 is rotated to move it into the sleeve 412. The movement of the sliding rod 413 compresses the outer wall of the slide rod 413, preventing the slide rod 413 from sliding inside the sleeve 412. The four sets of unfolded sleeves 412 and slide rods 413 can expand the bottom support range of the vehicle body 1, thereby improving the stability of the lifting bracket mechanism 2 and the buffer assembly 42 in supporting the highway bridge. Under the magnetic attraction of the first magnetic block 418 and the second magnetic block 419, the stored sleeve 412 can be fixed, preventing the sleeve 412 from rotating around the hinge point with the fixed plate 411 as the rotation center during the movement of the vehicle body 1. This structure can expand the support range of the vehicle body 1, thereby improving the stability of the support for the highway bridge.

[0029] Furthermore, the end of the positioning bolt 417 near the sleeve 412 is made of rubber, and the outer wall of the positioning bolt 417 is threaded into the inside of the sleeve 412. Under the pressure and restriction of the positioning bolt 417, the sliding rod 413 can be prevented from sliding inside the sleeve 412.

[0030] Furthermore, the outer wall of the second magnetic block 419 is fixedly installed on the outer wall of the vehicle body 1, and the first magnetic block 418 and the second magnetic block 419 are magnetically attracted to each other. Under the restriction of magnetic attraction, the sleeve 412 can be prevented from rotating during the movement of the vehicle body 1.

[0031] Example 2: Based on Example 1, a preferred embodiment of the construction support bracket device for highway bridges provided by this utility model is as follows: Figures 1 to 6 As shown: The buffer assembly 42 includes a base plate 421 fixedly installed on the end of the lifting bracket mechanism 2 away from the vehicle body 1. A sliding column 422 is slidably arranged inside the base plate 421. A spring 423 is sleeved on the outer wall of the sliding column 422. A support plate 424 is fixedly installed at the end of the sliding column 422. A damper 425 is fixedly installed at the bottom of the support plate 424.

[0032] In this embodiment, when the lifting bracket mechanism 2 pushes the buffer assembly 42 upward as a whole, it supports the highway bridge. During the support process, the highway bridge will be affected by factors such as load, temperature change, and concrete shrinkage during construction, resulting in deformation. If the buffer assembly 42 does not buffer, it will be squeezed, causing damage to the lifting bracket mechanism 2. The purpose of the buffering measures is to absorb these deformation energies and prevent the lifting bracket mechanism 2 from overloading. Therefore, the buffer assembly 42 needs to have a buffer space. The highway bridge squeezes the support plate 424, causing the sliding column 422 fixedly installed at the bottom of the support plate 424 to slide inside the base plate 421 and compress the spring 423 sleeved on the outer wall of the sliding column 422. The damper 425 buffers the swaying force generated by the spring 423, so that the buffer assembly 42 has a buffering function.

[0033] Furthermore, the end of the damper 425 away from the support plate 424 is fixedly installed on the top surface of the base plate 421, and one end of the spring 423 is fixedly installed on the top surface of the base plate 421. The end of the spring 423 away from the base plate 421 is fixedly installed on the bottom of the support plate 424. With the cooperation of the spring 423 and the damper 425, the deformed highway bridge can be buffered and supported, avoiding damage to the lifting bracket mechanism 2 by forced pressing.

[0034] In addition, there are four sliding pillars 422, divided into two groups, symmetrically distributed around the bottom center line of the support plate 424. Under the restriction of the sliding pillars 422, the support plate 424 can slide stably up and down.

[0035] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
