Description

TECHNICAL FIELD

[0001] The application relates to a construction engineering device, in particular to a bridge shock-absorbing support which is convenient to install and disassemble. BACKGROUND

[0002] The bridge generally refers to a structure erected on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, the bridge is also extended to the building erected to cross the ravines, poor geology or meet other traffic needs to make the traffic more convenient. The bridge is generally composed of an upper structure, a lower structure, a support and an accessory structure. The upper structure is also called a bridge span structure, which is the main structure for crossing obstacles. The lower structure includes an abutment, a pier and a foundation. The support is a force transmission device arranged at the support of the bridge span structure and the pier or the abutment. The accessory structure refers to the bridge head apron, the conical slope protection, the revetment, the diversion engineering and the like. For the temporarily erected bridge which is mostly composed of a steel structure, if the shock-absorbing support is not used, the bolts will be loosened due to vibration, and there is a safety hazard. After the bridge is erected, it needs to be disassembled. The shock-absorbing support in the prior art is relatively troublesome to disassemble. Therefore, there is room for improvement. SUMMARY

[0003] The application aims to provide a bridge shock-absorbing support which is convenient to install and disassemble.

[0004] The application achieves the above-mentioned purpose through the following technical scheme:

[0005] The application comprises an upper support, a connecting column, spring steel, a spring and a lower support. The two sides of the upper support are fixedly connected between the spring steel and the connecting column. The spring is arranged between the upper support and the connecting column. The lower end of the connecting column is fixedly provided with the lower support. The lower end of the lower support is provided with a quick-disassembly base. The lower end of the quick-disassembly base is provided with a base mounting plate.

[0006] Preferably, a shock-absorbing pad is arranged between the lower support and the quick-disassembly base.

[0007] Specifically, the quick-disassembly base is composed of a base, a buckle, a buckle pivot, a buckle spring, a pull rod, a screw rod, a cover plate and a cover plate screw. The lower support is provided with a lower support clamping groove. The buckle is rotationally connected between the buckle pivot and the base. The cover plate is fixed to the base through the cover plate screw. The buckle spring is located between the cover plate and the buckle. One end of the pull rod is fixed to the buckle. The other end of the pull rod penetrates out of the cover plate. The screw rod is threadedly connected with the cover plate. The end of the screw rod is located behind the buckle.

[0008] The application has the following beneficial effects:

[0009] The application discloses a bridge damping support which is convenient to install and disassemble. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1 is a structural schematic diagram of the application;

[0011] Figure 2 is Figure 1 A partial enlarged view of part A in the figure.

[0012] In the figure: 1-upper support, 2-connecting column, 3-spring steel, 4-spring, 5-lower support, 6-quick-release base, 7-damping pad, 51-lower support clamping groove, 61-base mounting plate, 62-base, 63-buckle, 64-buckle pivot, 65-buckle spring, 66-pull rod, 67-screw rod, 68-cover plate, 69-cover plate bolt. DETAILED DESCRIPTION

[0013] The application will be further described below in combination with the drawings:

[0014] As Figure 1 shown: the application comprises an upper support 1, a connecting column 2, spring steel 3, a spring 4 and a lower support 5, the two sides of the upper support are fixedly connected with the connecting column through the spring steel, the spring is arranged between the upper support and the connecting column, the lower end of the connecting column is fixedly provided with the lower support, the lower end of the lower support is provided with a quick-release base, and the lower end of the quick-release base is provided with a base mounting plate 61.

[0015] Preferably, a damping pad 7 is arranged between the lower support and the quick-release base.

[0016] Specifically, the quick-release base 6 is composed of a base 62, a buckle 63, a buckle pivot 64, a buckle spring 65, a pull rod 66, a screw rod 67, a cover plate 68 and a cover plate bolt 69, the lower support is provided with a lower support clamping groove 51, the buckle is rotationally connected with the base through the buckle pivot, the cover plate is fixed on the base through the cover plate bolt, the buckle spring is located between the cover plate and the buckle, one end of the pull rod is fixed on the buckle, the other end of the pull rod penetrates out of the cover plate, the screw rod is threadedly connected with the cover plate, and the end of the screw rod is located behind the buckle.

[0017] The present application adopts spring and spring steel double damping, when installing, the lower support is directly inserted into the base, the buckle is lifted and clamped in the lower support clamping groove, then the screw rod is rotated to resist the buckle to prevent the buckle from loosening, when disassembling, the screw rod is reversely rotated to make the screw rod away from the buckle, the pull rod is pulled to make the buckle separate from the lower support clamping groove, and then the lower support can be disassembled.

[0018] The basic principle and main features of the present application and the advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the present application.
