Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge engineering construction technology, and in particular to a bridge steel structure support frame. Background Technology
[0002] Bridge construction refers to a comprehensive engineering activity involving a series of planning, design, construction, and maintenance stages to build structures and their ancillary facilities that cross natural obstacles (such as rivers, canyons, and straits) or man-made obstacles (such as roads and railways) and connect two or more locations. In the field of bridge construction, steel structure support frames serve as crucial temporary or permanent support structures, and their performance and adaptability directly impact construction quality and efficiency. As bridge designs become increasingly complex, the requirements for support frames are becoming more stringent.
[0003] Traditional steel structure support frames for bridges have many limitations in design. From the perspective of structural adaptability, traditional support frames are mostly fixed structures, and their size and shape are difficult to change after manufacturing. However, in actual bridge construction, there are significant differences in the span, height, and alignment of different bridges. Fixed support frames cannot meet diverse construction needs. For example, when constructing curved bridges or bridges with variable cross-sections, traditional support frames cannot be flexibly adjusted to adapt to the special shape of the bridge, resulting in poor support effect and possibly affecting the overall structural stability of the bridge.
[0004] From the perspective of construction efficiency, the installation and adjustment process of traditional support frames is cumbersome and requires a lot of manual operation and time. For example, when setting up and adjusting the support frame, workers need to repeatedly measure and calibrate, which seriously affects the construction progress. In addition, the traditional support frame has a low reuse rate, and different projects often need to customize support frames of different specifications, which increases material costs and construction costs.
[0005] Therefore, in order to solve the above-mentioned problems of traditional bridge steel structure support frames and improve the adaptability and construction efficiency of the support frames, it is necessary to develop a new type of adjustable intelligent bridge steel structure support frame. Utility Model Content
[0006] To overcome the above shortcomings, this utility model provides a bridge steel structure support frame, which aims to improve the problems in the prior art where the size and shape of the support frame are difficult to change after manufacturing and the support frame installation and adjustment process is cumbersome.

As a further description of the above technical solution: The support plate is provided with an installation groove for mounting a laser rangefinder, which is used to measure the distance between the support plate and the supported bridge steel structure. As a further description of the above technical solution: The top of the support plate is also provided with buffer pads on both sides to buffer the impact of vibration on the support plate.

Beneficial effects
[0008] 1. In this utility model, in the horizontal direction, the cylinder can drive the adjusting guide rail to move along the supporting guide rail, thereby achieving adjustment in the front and rear directions; at the same time, the motor drives the bidirectional screw to rotate, which can make the two guide rail seats move towards or away from each other, thereby adjusting the span of the support frame in the left and right directions. In the vertical direction, the supporting plate is connected to the piston rod of the cylinder, and the height of the supporting plate can be adjusted by the cylinder. It has a multi-dimensional adjustment function and can well adapt to the support requirements of different bridge structures.

This intelligent monitoring and automatic adjustment mechanism enables the support frame to dynamically adapt to various changes in the bridge construction process. In complex construction environments, the support frame can sense these changes in real time and automatically adjust to ensure the uniform distribution of support force and the accuracy of support position.

[0014] Reference Figures 1-4This utility model provides an embodiment of a bridge steel structure support frame, including support rails 1 and adjusting rails 2. The two support rails 1 are horizontally arranged, providing a stable horizontal reference frame for the entire support frame. This ensures that the adjusting rails 2 can move and be positioned in a predetermined horizontal direction. Simultaneously, as the installation base for other components, the strength and stability of the support rails 1 directly affect the load-bearing capacity of the entire support frame, enabling it to withstand the loads transmitted from the bridge steel structure and providing reliable support for bridge construction. The two adjusting rails 2 are vertically arranged on the two support rails 1 and can move along the support rails 1, giving the support frame horizontal stability. The adjustable guide rail 2 allows for flexible adjustment, changing the front and rear support positions of the support frame to adapt to the support requirements of bridge steel structures with different positions and shapes. A connecting plate 3 is fixedly connected between the two support guide rails 1, and cylinders 4 are installed on both sides of the connecting plate 3. By controlling the extension and retraction of the piston rod of cylinder 4, the adjusting guide rail 2 can be precisely driven to move along the support guide rail 1, thereby quickly and accurately adjusting the support position of the support frame in the front and rear directions. Guide rail seats 5 are fixedly connected to both sides of the bottom of the adjusting guide rail 2, sliding on the support guide rail 1 to ensure the straightness and stability of the adjusting guide rail 2 during movement, preventing... To prevent deviation or wobbling and ensure the adjustment accuracy of the support frame, a fixing plate 6 is fixedly connected to the top of each adjusting guide rail 2. A double-acting screw 8 is installed between the two fixing plates 6. When the motor 7 drives the double-acting screw 8 to rotate, due to the interaction of the threads, the two guide rail seats 9 will move towards or away from each other along the double-acting screw 8. This structure enables rapid and accurate adjustment of the span in the left and right directions of the support frame. It can flexibly adjust the width of the support frame according to the actual size of the bridge and the support requirements, improving the adaptability and versatility of the support frame. Guide rail seats 9 are threaded on both sides of the surface of the double-acting screw 8. The guide rail seats 9 are slidably connected to the adjusting guide rail 2, ensuring the support... The stability of the support frame during left and right adjustment allows the support plate 11 to be moved precisely to the required position. The top of the guide rail seat 2 9 is equipped with a cylinder 2 10, which is mainly used to adjust the height of the support plate 11. By controlling the extension and retraction of the piston rod of the cylinder 2 10, the vertical position of the support plate 11 can be adjusted quickly and accurately, so that the support plate 11 can adapt to the support requirements of bridge steel structures of different heights. The support plate 11 is fixed on the cylinder 2 10, and a laser rangefinder 13 is set on the top of the support plate 11, which can monitor the distance between the support plate 11 and the bridge steel structure in real time and feed the data back to the control module to realize the automatic adjustment of the support frame. Reference Figures 1-4The output end of cylinder 4 is fixedly connected to the adjusting guide rail 2 on the same side. Two fixing plates 6 are fixed to both ends of the adjusting guide rail 2 respectively. A motor 7 is installed on the inner side of one of the fixing plates 6. A bidirectional screw 8 is connected to the output shaft of the motor 7. The support plate 11 is connected to the piston rod of cylinder 10. The height of the support plate 11 can be adjusted by cylinder 10. The support plate 11 is provided with a mounting groove 12. The mounting groove 12 is used to install the laser rangefinder 13. The mounting groove 12 can protect the laser rangefinder 13 from external collisions and interference, ensuring that the laser rangefinder 13 can work normally. The laser rangefinder 13 is used for... Measuring the distance between the support plate 11 and the supported bridge steel structure allows for real-time feedback of the measurement data to the control module, providing precise data for the automatic adjustment of the support frame. Through precise measurement by the laser rangefinder 13, the control module can promptly detect changes in the support position and automatically adjust the actions of cylinder 4, cylinder 10, and motor 7 to ensure the support frame is always in optimal support condition, improving the quality and safety of bridge construction. Buffer pads 14 are also installed on both sides of the top of the support plate 11 to buffer the impact of vibration on the support plate 11, which may be affected by various factors during bridge construction. Vibrations, such as those generated by the operation of mechanical equipment or wind loads, are absorbed and dispersed by the buffer pad 14. This reduces the impact of vibrations on the support plate 11, maintains the stability of the support plate 11, and prevents support failure or bridge structure damage caused by vibration. The surfaces of the support guide rail 1 and the adjusting guide rail 2 are coated with an anti-rust coating to improve the corrosion resistance of the support frame. The anti-rust coating isolates the guide rails from contact with corrosive media such as air and moisture, extending the service life of the guide rails and ensuring the stability and reliability of the support frame during long-term use. The system also includes a control module, which is connected to cylinder 4 and cylinder 2 respectively. 10. The motor 7 and the laser rangefinder 13 are electrically connected to receive the measurement data from the laser rangefinder 13 and control the actions of cylinder 4, cylinder 10 and motor 7 according to a preset program to achieve automatic adjustment of the support frame. It can receive the measurement data from the laser rangefinder 13, analyze and process it according to a preset program, and then issue commands to control the actions of cylinder 4, cylinder 10 and motor 7 to achieve automatic adjustment of the support frame. The application of the control module improves the intelligence level of the support frame, reduces the workload and errors of manual operation, and enables the support frame to adapt to various needs of bridge construction more accurately and quickly.
[0015] Working principle: The laser rangefinder 13 measures the distance between the support plate 11 and the supported bridge steel structure in real time and transmits the measured data to the control module in real time. After receiving the distance data from the laser rangefinder 13, the control module sends signals to the corresponding actuators according to the generated control commands. If forward and backward adjustment is required, the control module sends commands to the two cylinders 4 to control the extension and retraction of their piston rods, thereby moving the two drive adjustment rails 2 along the support rails 1 to achieve precise forward and backward adjustment. If left and right adjustment is required, the control module controls the operation of the motor 7, which drives the bidirectional screw 8 to rotate, causing the two guide rail seats 9 to move in the predetermined direction to complete the adjustment of the left and right span. If height adjustment is required, the control module controls the action of the cylinder 10 to change the height of the support plate 11 by extending and retracting the piston rod, ensuring that it always maintains the optimal support distance with the supported bridge steel structure.
