Description

Technical Field

[0001] The present application relates to the technical field of support devices, and in particular to a support device for civil engineering. Background Art

[0002] Civil engineering usually refers to civil engineering projects, which include a wide range of infrastructure projects, such as houses, roads, bridges and water conservancy projects. Pipes are usually required in the construction of civil engineering projects. Currently, support devices are needed to support the pipes. Civil engineering support devices are a type of equipment used in construction. These support devices are usually made of metal to facilitate reuse and carry heavier loads.

[0003] For example, a Chinese patent with announcement number CN219198520U discloses a support device for civil engineering, including a base, a plurality of shells are fixedly connected to the outside of the base, a compression spring is fixedly connected to the outside of the base and located inside the shell, an adjustment plate is fixedly connected to the other end of the compression spring, two triangular blocks are symmetrically fixedly connected to the two sides of the adjustment plate, a first cross bar is connected to the rotation of the adjustment plate away from the compression spring, a first roller is rotatably connected to the outside of the first cross bar, two rotating rods are symmetrically fixedly connected to the inner wall of the shell and located on both sides of the adjustment plate, and a clamping plate is rotatably connected to the outside of the rotating rod; the present application places a pipe between the adjustment plate and the two clamping plates, and the pipe drives the adjustment plate and the triangular blocks to descend. During the descent of the triangular blocks, the telescopic spring gradually extends, driving the clamping plate to rotate around the rotating rod, and the two clamping plates move away from each other until the pipe contacts the first roller. The device can clamp pipes of different sizes.

[0004] Although the device has many beneficial effects, the following problems still exist: the traditional support equipment is not designed with the function of flexibly adjusting the height of the pipeline, which means that once the pipeline is installed in place, its height is fixed and cannot be adjusted according to actual construction needs or later maintenance requirements, which limits the flexibility and efficiency of construction; in addition, since a large amount of dust is generated during the construction process, this dust can easily settle on the surface of the pipeline, which will not only affect the appearance of the pipeline, but may also affect the normal function of the pipeline.

[0005] Therefore, in order to solve the above problems, the present application provides a supporting device for civil engineering.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0011] Preferably, a dust removal part connected to the pressure chamber of the fixed tube is installed on the outer side of the lifting part, and the dust removal part includes a pressure relief valve fixedly arranged on the side wall of the bottom end of the fixed tube, and a guide tube connected to the pressure relief valve, and the other end of the guide tube extends to the tube body clamped by the clamping part.

[0015] The electric push rod is controlled so that its telescopic end pushes the clamping block together to clamp the pipe; further, the air pump is turned on to allow the gas to enter the fixed pipe along the air pipe. At this time, the air pressure inside the fixed pipe increases, which will push the piston rod in the fixed pipe to move upward. The piston rod further drives the lifting column and the mounting part and the clamping part above the lifting column to move upward through the connecting block, so as to flexibly adjust the height of the pipe; when no support is needed, the air pump is turned off and the pressure relief valve is activated. The pressure relief valve relieves the pressure in the inner cavity of the fixed pipe, and the gas in the fixed pipe is discharged to the clamping block through the guide pipe, and the inner wall of the clamping block is cleaned for the next use.

[0020] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0021] Example 1: Reference Figure 1-Figure 3 A supporting device for civil engineering includes a supporting part 1, which includes a mounting plate 101, supporting legs 102 fixedly mounted at the four corners of the bottom of the mounting plate 101, and a fixing block 103 fixedly mounted at the top of the mounting plate 101. A longitudinally arranged lifting part 2 is installed in the middle of the mounting plate 101. The lifting part 2 includes a fixed tube 201, a piston rod 202, a connecting block 203 and a lifting column 204, wherein the fixed tube 201 is mirror-mounted directly below the mounting plate 101, and a piston rod 202 is movably sleeved in the fixed tube 201. The top end of the piston rod 202 is fixedly connected to the bottom end of the lifting column 204 movably plugged into the fixed block 103 through the connecting block 203. The bottom of the inner cavity of the fixed tube 201 is a pressure chamber, and the lifting height of the piston rod 202 increases with the increase of the pressure in the pressure chamber. The top end of the lifting column 204 is provided with a clamping part 4 for clamping a tube body through the mounting part 3.

[0022] The lifting part 2 further includes an air pipe 205 and an air pump 206 , wherein the two top branches of the air pipe 205 are communicated with the bottom ends of the two piston rods 202 , and the bottom branch of the air pipe 205 is communicated with the exhaust end of the air pump 206 .

[0023] The inner cavities at the bottom ends of the mirror-image piston rods 202 are connected via a conduit.

[0024] A dust removal part 5 connected to the pressure chamber of the fixed pipe 201 is installed on the outer side of the lifting part 2. The dust removal part 5 includes a pressure relief valve 501 fixedly arranged on the side wall of the bottom end of the fixed pipe 201, and a guide pipe 502 connected to the pressure relief valve 501, and the other end of the guide pipe 502 extends to the pipe body clamped by the clamping part 4; the inlet pressure of the air pump 206 can be greater than the pressure relief of the pressure relief valve 501. When both are enabled at the same time, there will be a continuous airflow passing through the guide pipe 502, which can not only meet the supporting function of the piston rod 202, but also continuously blow dust to the pipeline.

[0025] The mounting portion 3 includes a U-shaped frame 301 and a positioning block 302 , wherein the U-shaped frame 301 is fixedly mounted on the top end of the lifting column 204 , and the positioning block 302 for fixing the top end of the flow guide tube 502 is mounted on the U-shaped frame 301 .

[0026] The clamping portion 4 includes an electric push rod 401 and a clamping block 402 , wherein the electric push rod 401 is mirror-imaged at the top of the U-shaped frame 301 , and the clamping block 402 is fixedly mounted at the telescopic end of the electric push rod 401 .

[0027] The implementation principle of a civil engineering support device in the embodiment of the present application is as follows:

[0028] The electric push rod 401 is controlled so that its telescopic end pushes the clamping block 402 together to clamp the pipe; further, the air pump 206 is turned on to allow the gas to enter the fixed pipe 201 along the air pipe 205. At this time, the air pressure inside the fixed pipe 201 increases, which will push the piston rod 202 in the fixed pipe 201 to move upward. The piston rod 202 further drives the lifting column 204 and the mounting part 3 and the clamping part 4 above the lifting column 204 to move upward through the connecting block 203, so as to flexibly adjust the height of the pipe; when no support is needed, the air pump 206 is turned off and the pressure relief valve 501 is activated. The pressure relief valve 501 relieves the pressure in the inner cavity of the fixed pipe 201, and the gas in the fixed pipe 201 is discharged to the clamping block 402 through the guide pipe 502 to clean the pipe.
