Description

Technical Field

[0001] This utility model belongs to the technical field of bridge construction equipment, and specifically relates to a horizontal adjustment device for the main beam assembly support frame of a bridge erecting machine. Background Technology

[0002] In bridge construction, the bridge erecting machine is a key piece of equipment used to erect precast beams. The assembly accuracy of the main beam has a crucial impact on the overall performance of the bridge erecting machine and the quality of bridge erection. During the assembly of the main beam, a support frame is required to support it. However, due to factors such as poor ground flatness and uneven geological conditions at the construction site, the support frame often fails to maintain a horizontal position, leading to problems such as tilting and twisting of the main beam during assembly, thus affecting the stability and safety of the bridge erecting machine.

[0003] Existing methods for leveling support frames often rely on manual measurement combined with simple wedge blocks or jacks. This approach is not only inefficient and unsuitable for large-scale construction, but also lacks precision, with significant errors in manual measurement and operation, failing to guarantee the high precision required for main beam assembly. Furthermore, existing adjustment devices are structurally inflexible, occupying considerable space and hindering on-site setup and operation. Summary of the Invention

[0004] In order to solve the above problems, the purpose of this utility model is to provide a horizontal adjustment device for the main beam assembly support frame of a bridge erecting machine.

[0005] To achieve the above objectives, the horizontal adjustment device for the main beam assembly support frame of the bridge erecting machine provided by this utility model includes a base, columns, a tray, jacks, a level, safety limit blocks, and safety pins. The base is horizontally positioned to provide stable support. Multiple pin holes are spaced along the height direction on the columns, and the lower ends of four columns are fixed to the four corners of the top surface of the base. The lower ends of two jacks are fixed to the top surface of the base between two columns on the same side and connected to a synchronous control system. The tray is horizontally positioned above the base and inside the four columns. The level is installed at the center of the top surface of the tray. At least two safety limit blocks are installed on both sides of the top surface of the tray to limit the position of the lower end of the main beam of the bridge erecting machine. A safety pin is inserted into a pin hole at the same height on each column, and the inner part of the safety pin rests on the bottom surface of the tray to lock the position of the tray in the vertical direction.

[0006] The base, column, tray, safety limit block, and safety pin are all made of steel.

[0007] The jack is an electric hydraulic jack.

[0008] The level is a high-precision electronic level.

[0009] The horizontal adjustment device for the main beam assembly support frame of the bridge erecting machine provided by this utility model has the following beneficial effects:

[0010] 1) Lightweight structure; 2) Low cost and easy to manufacture; 3) Simple and convenient operation, reducing human error; 4) Compatible with main beams of various sizes; 5) Highly expandable, easy to operate, and highly safe; 6) Enables rapid and precise adjustment of the support frame's horizontal state, greatly improving the assembly accuracy and efficiency of the bridge erecting machine's main beam; 7) Improves the adjustment accuracy and flexibility of the adjustment device; 8) Small footprint, facilitating site layout and operation; 9) Enhances installation efficiency and safety, demonstrating significant technological advancement and practicality.

[0013] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1-2 As shown, the horizontal adjustment device for the main beam assembly support frame of the bridge erecting machine provided by this utility model includes a base 1, columns 2, a tray 3, jacks 4, a level 5, safety limit blocks 6, and safety pins 7. The base 1 is horizontally positioned to provide stable support. Multiple pin holes are spaced along the height direction on the columns 2, and the lower ends of the four columns 2 are fixed at the four corners of the top surface of the base 1. The lower ends of two jacks 4 are fixed on the top surface of the base 1 between two columns 2 on the same side, and connected to a synchronous control system. The tray 3 is horizontally positioned above the base 1 and inside the four columns 2. The level 5 is installed at the center of the top surface of the tray 3. At least two safety limit blocks 6 are installed on both sides of the top surface of the tray 3 to limit the position of the lower end of the main beam 8 of the bridge erecting machine. A safety pin 7 is inserted into the pin holes at the same height on each column 2, and the inner part of the safety pin 7 rests on the bottom surface of the tray 3 to lock the position of the tray 3 in the vertical direction.

[0015] The base 1, column 2, tray 3, safety limit block 6, and safety pin 7 are all made of steel.

[0016] The jack 4 is an electric hydraulic jack.

[0017] The level 5 is a high-precision electronic level.

[0018] The method of using the horizontal adjustment device for the main beam assembly support frame of the bridge erecting machine provided by this utility model is described as follows: After the horizontal adjustment device for the main beam assembly support frame of the bridge erecting machine is assembled, the workers place the end of the main beam 8 of the bridge erecting machine on the top surface of the tray 3 between the safety limit blocks 6. Then, the level 5 installed in the middle of the tray 3 is used to observe whether the left and right sides of the main beam 8 of the bridge erecting machine are level. If the two sides are uneven, the jacks 4 on one side can be adjusted individually for leveling. After the main beam 8 of the bridge erecting machine is assembled, the device is disassembled, stored in the warehouse, and awaited for the next use.
