Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anti-seismic support, in particular to an anti-seismic support for supporting multiple pipelines. BACKGROUND

[0002] During the construction process of engineering construction, pipeline and cable bridge laying are often needed. The pipeline is used for conveying tap water, fire water and natural gas, etc., and the cable bridge is used for arranging cables, network cables, etc. If these pipelines are directly fixed on the wall, the fluid flowing in the pipeline will generate corresponding noise, which will affect the normal rest of residents through solid medium conduction. Therefore, an anti-seismic support is usually arranged to support the pipeline to reduce the influence of noise on the normal life of residents.

[0003] When the pipeline is supported by the anti-seismic support, the pipeline rack is usually first installed on the roof, and then the pipeline is installed and fixed. For multiple-layered pipelines, they are sequentially installed and fixed according to the predetermined order. This long-time lifting operation affects the comfort and work efficiency of the operator.

[0004] According to the search, a multiple-pipeline supporting anti-seismic support (CN219282739U) is disclosed. Before the pipeline is installed, the secondary installation pipe groove between the sliding base and the secondary installation rack is separated by rotating the first transmission shaft. Then, the first transmission shaft is rotated to drive the sliding base to move upward, and at the same time, the second transmission shaft is rotated to separate the main installation pipe groove between the main installation rack and the sliding base, so as to place the main pipeline in the main installation pipe groove to install the main pipeline. Thus, the long-time lifting operation of the operator is avoided when sequentially installing and fixing the multiple-layered pipelines. However, the multiple-pipeline supporting anti-seismic support only sets a rubber pad in the installation base, and the jacking mechanism is set in the interior and top of the rubber pad. This way has poor anti-seismic effect of the support. SUMMARY

[0009] Still further, the driving mechanism comprises a first motor, a driving shaft, two driving bevel gears, two driven bevel gears, a connecting rod and a screw rod, the first motor is installed at one end of the top end of the fixing frame, the driving shaft is rotatably connected with the fixing frame, one end of the driving shaft is coaxially connected with the output end of the first motor, the two driving bevel gears are sleeved on the driving shaft and are coaxially fixedly connected with the driving shaft, the two driven bevel gears are respectively engaged with the two driving bevel gears, one end of the connecting rod is coaxially fixedly connected with one end of the driven bevel gear, the connecting rod is rotatably connected with the fixing frame, one end of the screw rod is coaxially fixedly connected with the other end of the connecting rod, the other end of the screw rod penetrates through the second connecting plate and is threadedly connected with the second connecting plate, the screw rod is located in the fixing frame and is rotatably connected with the fixing frame.

[0010] As a further scheme of the present application, the first clamping seat and the second clamping seat correspond to each other, and the third clamping seat and the fourth clamping seat correspond to each other.

[0011] As a further scheme of the present application, the fixed seat is provided with a moving groove matched with the first extrusion plate, and the bottom of the fixed frame is provided with a sliding groove matched with the second connecting plate.

[0012] As a further scheme of the present application, the fixed frame is provided with a plurality of rotating grooves matched with the driving bevel gear and the driven bevel gear, and the driving bevel gear and the driven bevel gear are rotationally connected with the inner wall of the rotating groove.

During the upward movement, after the third clamping seat and the fourth clamping seat abut and clamp the small-size pipeline, the second connecting plate continues to move upward, driving the first extrusion plate to move upward, and driving the second clamping seat to abut against the first clamping seat and clamp the large-size pipeline. In this way, multiple pipelines of different sizes are clamped and fixed, reducing the lifting operation time, improving the comfort and work efficiency of the operator. Then the second connecting plate continues to move upward by a distance, and the first spring and the second spring are contracted during the upward movement of the second connecting plate. Finally, the first motor is turned off, and the driving shaft is braked by the first motor to prevent the second connecting plate from moving downward.

[0016] 2. In the present application, the first spring and the second spring elastically extrude the first connecting plate and the second extrusion plate, and the first spring and the second spring are in a contracted state. Even if the pipeline shakes violently, the first spring and the second spring play a role in shock absorption, and the third clamping seat and the fourth clamping seat remain in an abutting state, and the second clamping seat and the first clamping seat also remain in an abutting state. In this way, the pipeline will not fall off the bracket, improving the clamping effect and having higher shock resistance. BRIEF DESCRIPTION OF DRAWINGS
