Abstract
Description
Technical Field
[0001] This application relates to the field of convenient assembly bridge erecting machine technology, and in particular to a support structure for a convenient assembly bridge erecting machine. Background Technology
[0002] A bridge erecting machine is a large construction machine specifically used in the bridge construction process to erect prefabricated bridge beams onto bridge piers or abutments. Its main function is to lift the bridge beams, transport them to the designated location, and then lower them.
[0003] The installation of support beams in existing bridge erecting machine support structures is cumbersome and inefficient, requiring more time and manpower for assembly. This slows down the overall assembly progress of the bridge erecting machine, extending the construction period and increasing costs. Furthermore, the conventional method for moving the bridge erecting machine relies on its wheels rolling along a track. This method suffers from insufficient dynamic stability. When encountering uneven tracks, relying solely on the wheels to support the main body can easily cause the entire device to sway, increasing the risk of overturning. Therefore, we propose a convenient, modular bridge erecting machine support structure. Utility Model Content

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
[0035] This utility model provides, for example Figure 1-5 The illustrated convenient assembly bridge erecting machine support structure includes a support beam 1, with several threaded holes 6 on both sides of the support beam 1 and several limiting grooves 7 on the bottom of the support beam 1, and also includes:
[0036] Four support bases 3 are set below the support beam 1. Each of the four support bases 3 has a support leg 2. Each of the four support legs 2 has an L-shaped fixing plate 4 fixedly installed on its top. Each of the four L-shaped fixing plates 4 has a limit block 13 fixedly installed on its top. Each of the four limit blocks 13 is snapped into the corresponding limit groove 7. Each of the four L-shaped fixing plates 4 has four bolts 5. One end of each of the four bolts 5 passes through one side of the L-shaped fixing plate 4 and extends into the corresponding threaded hole 6.
[0037] Four sets of lifting components are located in four support bases 3, and are used to drive the four support legs 2 to lift.
[0038] Four sets of support components are located on four support bases 3 respectively, and are used to fix the four support bases 3 respectively.
[0039] When assembling the bridge erecting machine, personnel move the four support bases 3 to their designated support positions. Then, the support beam 1 is placed on the four L-shaped fixing plates 4, and the limiting blocks 13 on the L-shaped fixing plates 4 are engaged with the corresponding limiting grooves 7 at the bottom of the support beam 1 to ensure the support beam 1 is positioned correctly. Next, personnel use an adjustable wrench to turn the four bolts 5 on one of the L-shaped fixing plates 4, thus fixing one of the L-shaped fixing plates 4 to the support beam 1. This process is repeated to fix the remaining three L-shaped fixing plates 4 to the support beam 1, ensuring the bridge erecting machine can be quickly assembled without complex processes, effectively improving assembly efficiency. To improve efficiency and shorten the installation time of the bridge erecting machine, when the height of the support beam 1 needs to be adjusted, the lifting assembly moves the support leg 2 upward, which in turn moves the L-shaped fixing plate 4 and the limiting block 13 upward, thereby moving the support beam 1 upward. Personnel can adjust the height of the support beam 1 according to the actual construction situation to meet the construction requirements of different terrains and bridge structures, thus improving the adaptability and versatility of the bridge erecting machine's support structure. When the entire device needs to be moved, the fixing assembly supports the support base 3 to ensure that there will be no shaking or vibration when encountering uneven tracks, further improving the stability of the support structure and preventing overturning accidents.
[0040] The lifting assembly includes:
[0041] A fixing groove 14 is formed inside the support base 3. A sliding groove 15 is formed inside the support base 3 and located at the top of the fixing groove 14. A hydraulic cylinder 16 is fixedly installed inside the fixing groove 14. The bottom end of the support leg 2 is located inside the sliding groove 15. The output end of the hydraulic cylinder 16 extends into the sliding groove 15 and is tightly welded to the bottom of the support leg 2.
[0042] Simultaneously, the power supply to the four hydraulic cylinders 16 is turned on and started. The output shaft of the hydraulic cylinders 16 drives the support leg 2 to move upward in the slide groove 15. The upward movement of the support leg 2 drives the L-shaped fixing plate 4 and the limiting block 13 to move upward, thereby driving the support beam 1 to move upward. Personnel can adjust the height of the support beam 1 according to the actual construction situation to meet the construction requirements of different terrains and bridge structures, thus improving the adaptability and versatility of the bridge erecting machine support structure.
[0043] The four support legs 2 are slidably connected to the four slide grooves 15 respectively.
[0044] Specifically, it ensures that the support leg 2 can slide within the slide groove 15.
[0045] Supporting components include:
[0046] Four grooves 11 are formed on the support base 3. Hydraulic telescopic rod 10 and hydraulic telescopic rod 2 12 are rotatably installed on one side of the inner wall of each of the four grooves 11. Hydraulic telescopic rod 10 is located above hydraulic telescopic rod 2 12. The output ends of the four hydraulic telescopic rods 2 12 are rotatably connected to the periphery of the four hydraulic telescopic rods 10. Support feet 9 are rotatably installed on the output ends of the four hydraulic telescopic rods 10.
[0047] In this process, the four hydraulic telescopic rods 12 on the support base 3 are powered on and started. The output shaft of the hydraulic telescopic rod 12 drives the corresponding hydraulic telescopic rod 10 to rotate around the connection point with the corresponding groove 11 until the hydraulic telescopic rod 10 reaches the appropriate angle and position. Then, the hydraulic telescopic rod 10 is powered on and started. The output shaft of the hydraulic telescopic rod 10 drives the support foot 9 to move down until the support foot 9 contacts the ground, ensuring that the support base 3 can be supported. This ensures that there will be no shaking or vibration when encountering uneven tracks, further improving the stability of the support structure.
[0048] The bottom of support foot 9 has anti-slip texture.
[0049] The anti-slip texture increases the contact area between the support foot 9 and the ground, thus increasing friction.
[0050] Bolt 5 is threadedly connected to L-shaped fixing plate 4 and threaded hole 6. L-shaped fixing plate 4 and limiting block 13 are integrally formed. Limiting block 13 is inserted into limiting groove 7.
[0051] Under the action of the thread, one end of the bolt 5 can slide within the L-shaped fixing plate 4 and the threaded hole 6. This ensures the stability of the structure of the L-shaped fixing plate 4 and the limiting block 13, and ensures that the limiting block 13 can be inserted into the limiting groove 7, thereby limiting the support beam 1.
[0052] Each of the four support bases 3 has a rotatable caster wheel 8 mounted on its bottom.
[0053] Specifically, it is ensured that the four movable wheels 8 can drive the support base 3 to move, thereby driving the entire device to move.
[0054] Working Principle: When using this convenient assembly-type bridge erecting machine support structure, if the bridge erecting machine needs to be assembled, the operator uses the movable wheels 8 at the bottom of the support base 3 to move the four support bases 3 to the predetermined support positions. Then, the support beam 1 is placed on the four L-shaped fixing plates 4, and the limiting blocks 13 on the L-shaped fixing plates 4 are inserted into the corresponding limiting grooves 7 at the bottom of the support beam 1 to ensure that the support beam 1 is limited. Then, the operator uses an adjustable wrench to turn the four bolts 5 on one of the L-shaped fixing plates 4. Under the action of the threads, one end of the bolt 5 passes through the L-shaped fixing plate 4 and extends into the corresponding threaded hole 6, fixing one of the L-shaped fixing plates 4 to the support beam 1. According to the above operation... The remaining three L-shaped fixing plates 4 are then fixed to the support beam 1, ensuring that the support beam 1 and the four support bases 3 can be quickly assembled without complicated tools and processes, effectively improving assembly efficiency and shortening the installation time of the bridge erecting machine. When it is necessary to adjust the height of the support beam 1, the operator simultaneously connects and starts the four hydraulic cylinders 16. The output shaft of the hydraulic cylinder 16 drives the support leg 2 to move upward in the slide groove 15. The upward movement of the support leg 2 drives the L-shaped fixing plate 4 and the limit block 13 to move upward, thereby driving the support beam 1 to move upward. The operator can adjust the height of the support beam 1 according to the actual construction situation to meet the construction requirements of different terrains and bridge structures, improving the adaptability and versatility of the bridge erecting machine's support structure.
[0055] When the entire device encounters unevenness on the track while moving along the track, the operator simultaneously connects and starts the four hydraulic telescopic rods 12 on the support base 3. The output shaft of the hydraulic telescopic rod 12 drives the corresponding hydraulic telescopic rod 10 to rotate around the connection point with the corresponding groove 11 until the hydraulic telescopic rod 10 reaches the appropriate angle and position. Then, the hydraulic telescopic rod 10 is simultaneously connected and started. The output shaft of the hydraulic telescopic rod 10 drives the support foot 9 to move down until the anti-slip texture at the bottom of the support foot 9 contacts the ground, ensuring that the support base 3 can be supported. This ensures that there will be no shaking or vibration when moving on uneven tracks, further improving the stability of the support structure and preventing overturning accidents.
[0056] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
