Technical Field

[0001] This utility model belongs to the field of bridge construction equipment technology, and specifically relates to a shock-resistant beam drop pier cap jack transfer device. Background Technology

[0002] In bridge construction, the construction of seismic-resistant pier caps is crucial. Jacks, as important lifting equipment, need to be moved during the box girder erection stage. Currently, most existing jack transfer methods rely on manual handling or simple auxiliary tools. Manual handling is not only labor-intensive and inefficient, but also poses significant safety risks, such as jack slippage causing injury or death. When using simple auxiliary tools, the jack support position is difficult to guarantee, affecting the quality of subsequent box girder erection and consequently negatively impacting the overall bridge construction. Therefore, developing an efficient, safe, and precisely positioned seismic-resistant pier cap jack transfer device is of significant practical importance. Summary of the Invention

[0005] The anti-vibration beam pier cap jack transfer device also includes railings installed on both sides of the tray, with the railings being 1200mm long, 600mm wide, and 200mm thick.

[0006] The base diameter of the bullseye bearing is 100mm, and the ball diameter is 50mm.

[0007] The dimensions of the tray are 1200mm*600mm.

[0008] The slide bar has a diameter of 10mm and a length of 600mm.

[0009] The diameter of the caster wheel is 100mm.

[0010] The anti-vibration beam pier cap jack transfer device provided by this utility model has the following beneficial effects: 1) It is safe and effective, and can effectively protect the workers and jacks; 2) It is easy to construct, simple to operate, and easy to disassemble, which can improve the efficiency of jack transfer; 3) It improves the construction quality, prevents the jack from colliding with the pier cap and causing damage to the pier cap, and reduces costs; 4) It can be recycled, and is safe, efficient, convenient, accurate, labor-saving and labor-saving.

[0014] The anti-vibration beam-dropping pier cap jack transfer device provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1 , Figure 2 As shown, the anti-vibration pier cap jack transfer device provided by this utility model is installed in the pier cap groove 9 on the bridge. It includes bull's eye bearings 1, trays 3, support legs 4, safety locks 5, electric telescopic rods 6, sliding bars 7, and casters 8. The tray 3 is horizontally arranged. Multiple bull's eye bearings 1 are spaced apart on the top surface of the tray 3 for placing jacks 10. The support legs 4 are adjustable length structures composed of upper and lower support legs. The upper ends of at least four support legs 4 are symmetrically connected to both sides of the bottom surface of the tray 3. Each support leg 4 has a caster 8 installed at its lower end that can roll on the bottom surface of the pier cap groove 9. A safety lock 5 is installed at the connection between the upper and lower support legs to ensure the safety of the device and the jacks 10 on it. The upper ends of at least two electric telescopic rods 6 are spaced apart in the middle of the bottom surface of the tray 3. Multiple sliding bars 7 are placed in rows on the top surface of the pier cap.

[0016] The anti-vibration beam pier cap jack transfer device also includes railings 2 installed on both sides of the tray 3. The railings 2 are 1200mm long, 600mm wide, and 200mm thick.

[0017] The base diameter of the bullseye bearing 1 is 100mm, and the diameter of the ball bearing is 50mm.

[0018] The dimensions of the tray 3 are 1200mm*600mm.

[0019] The slide bar 7 has a diameter of 10mm and a length of 600mm.

[0020] The diameter of the universal wheel 8 is 100mm.

[0021] The method of using the anti-seismic beam pier cap jack transfer device provided by this utility model is described as follows: This device is mainly used for the transfer of anti-seismic beam pier cap jacks, such as... Figure 3 As shown, when it is necessary to move the jack 10 from the sides of the top surface of the pier cap where the box girder has been erected to the sides of the top surface of the pier cap where the box girder has not been erected, the workers first place the device into the groove 9 of the pier cap, close to the position of the jack 10. Then, according to the depth of the groove 9 of the pier cap, the lengths of the upper and lower legs of the support leg 4 are adjusted until the bull's eye bearing 1 on the tray 3 is flush with the top surface of the pier cap. Then, the safety lock 5 is locked. The jack 10 is then retracted using the pump station. A row of slide bars 7 leading to the device is then placed under the jack 10. The jack 10 is moved to the bull's eye bearing 1 of the device by rolling the slide bars 7. On the bullseye bearing 1, the device, along with the jack 10, is moved along the length of the groove 9 of the pier cap from one end of the top surface of the pier cap to the other using the casters 8 at the lower end of the outrigger 4. All the slide bars 7 are moved to the position on the top surface of the pier cap where the jack 10 is to be removed. Then, the height of the device is adjusted using the electric telescopic rod 6 until the bullseye bearing 1 and the upper end of the slide bar 7 are at the same level. Finally, the workers slide the jack 10 from the device onto the slide bar 7 and then transport it to the beam erection site. After the operation is completed, the device is disassembled, stored in the warehouse, and awaited for the next transfer and use of the jack 10.
