Description

Technical Field

[0001] The utility model relates to the field of highway construction, and particularly relates to a highway construction protection fence. Background Technique

[0002] The highway construction protection fence is a tool for isolation and warning, which is applied to scenarios such as highway construction that require temporary isolation and warning. It mainly reflects separating the construction area from the normal traffic area to ensure the safe progress of construction.

[0003] Although the traditional highway construction protection fence has the functions of isolation and warning, due to a large amount of dust generated at the construction site, the protective fence is not ideal in dealing with dust, and at the same time, the dust will also accumulate outside the protective fence, which is not conducive to the long-term use of the protective fence. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a highway construction protection fence, which can effectively solve the technical problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A highway construction protection fence includes a support base. A plurality of support rods are fixedly installed in parallel at one side position of the upper part of the support base, and two support columns are fixedly installed in parallel at both side positions of the upper part of the support base. A dust suction structure is arranged at the tops of the two support columns and the plurality of support rods. The dust suction structure includes a first horizontal pipe. A front adapter seat is fixedly installed at a position close to the front end of the outside of the first horizontal pipe. A connecting seat is fixedly installed on one side of the front adapter seat. A front connecting pipe is rotatably installed on one side of the connecting seat. An adjusting plate is sleeved on the outside of the front connecting pipe. A rear adapter seat is fixedly installed at a position close to the rear end of the outside of the first horizontal pipe. A rear connecting pipe is fixedly installed on one side of the rear adapter seat. An adjusting seat is threadedly installed at the rear part of the rear adapter seat. A piston is fixedly installed between the adjusting seat and the rear adapter seat. A second horizontal pipe is fixedly installed between the front adapter seat and the rear adapter seat.

[0007] As a further scheme of the utility model, rectangular slot holes are opened at both the upper and lower ends of the first horizontal pipe, and the support columns, the first horizontal pipe, the front adapter seat, the rear adapter seat and the second horizontal pipe are connected in a through manner.

[0008] As a further scheme of the utility model, the front connecting pipe is rotatably connected to the connecting seat through a special-shaped column. External threads are opened on the outside of the front connecting pipe, internal threads are opened in the inside of the rear connecting pipe, and the external threads and the internal threads are adaptively matched.

[0009] As a further solution of the present utility model, a pushing and removing structure is provided between the first horizontal pipe and the support rod and the second horizontal pipe respectively. The pushing and removing structure includes a filter screen, the filter screen is fixedly installed at the upper and lower ends of the first horizontal pipe, and a push rod is slidably installed outside the filter screen, and air delivery grooves are opened at both ends of the push rod.

[0010] As a further solution of the present utility model, a groove is opened in the middle of the push rod, the filter screen is adaptively matched with the groove, and the air delivery grooves are on the same vertical line as the openings of the support column, the front adapter seat and the rear adapter seat.

[0011] As a further solution of the present utility model, the shape of the support seat is trapezoidal, and the support rods are symmetrically installed on both sides of the upper part of the support seat.

[0012] The beneficial effects of the present utility model are as follows: By setting the dust suction structure, the dust generated at the construction site can be effectively absorbed. The first horizontal pipe and the second horizontal pipe are fixedly installed at the top of the device. Under the action of the air extractor, the dust enters through the second horizontal pipe and is transported to the front connecting pipe. Since slot holes are opened on the outer parts of the second horizontal pipe and the support column, the dust suction range can be increased, making the dust cleaning more thorough. At the same time, the device is provided with a front connecting pipe and a rear connecting pipe, and multiple devices can be connected in series to adapt to highway construction of different lengths, and the assembly and disassembly are convenient.

[0013] By setting the pushing and removing structure, since the dust particles pass through the filter screen when entering the first horizontal pipe, the blockage of the first horizontal pipe is avoided. However, a large amount of dust particles will accumulate outside the filter screen, and if not cleaned in time, it is easy to cause blockage. The device is provided with a push rod. During the forward movement of the push rod, the dust particles outside the filter screen will be scraped off. At the same time, a gap is generated between the push rod and the first horizontal pipe, and the dust particles are discharged through the gap, solving problems such as blocked air valves, and at the same time extending the service life of the device.

A connection seat 7 is fixedly installed on one side of the front adapter seat 6. A front connecting pipe 8 is rotatably installed on one side of the connection seat 7. An adjusting plate 9 is sleeved on the outside of the front connecting pipe 8. A rear adapter seat 10 is fixedly installed at a position near the rear end of the outside of the first horizontal pipe 5. A rear connecting pipe 11 is fixedly installed on one side of the rear adapter seat 10. An adjusting seat 12 is threadedly installed at the rear part of the rear adapter seat 10. A piston 13 is fixedly installed between the adjusting seat 12 and the rear adapter seat 10. A second horizontal pipe 14 is fixedly installed between the front adapter seat 6 and the rear adapter seat 10.

[0023] During use, the front connecting pipe 8 is connected to an air extractor, and the adjusting seat 12 is adjusted to seal the rear connecting pipe 11. In order to make the gas output from the support column 3, the first horizontal pipe 5, the front adapter seat 6, the rear adapter seat 10 and the second horizontal pipe 14, by connecting the support column 3, the first horizontal pipe 5, the front adapter seat 6, the rear adapter seat 10 and the second horizontal pipe 14 in a through manner, the gas flow is ensured.

[0024] In this embodiment, the front connecting pipe 8 is rotatably connected to the connection seat 7 through a special-shaped column. External threads are provided on the outside of the front connecting pipe 8, internal threads are provided in the inside of the rear connecting pipe 11, and the external threads and the internal threads are adaptively matched.

[0025] To adapt to the construction site, enable multiple devices to be connected together, make the front connecting pipe 8 and the rear connecting pipe 11 connect to each other, and at the same time adjust the end adjusting seat 12 to close the end rear connecting pipe 11, then the series connection of multiple devices can be achieved.

[0026] In this embodiment, a pushing and removing structure 15 is provided between the first horizontal pipe 5 and the support rod 2 and the second horizontal pipe 14 respectively. The pushing and removing structure 15 includes a filter screen 16. The filter screen 16 is fixedly installed at the upper and lower ends of the first horizontal pipe 5, and a push rod 17 is slidably installed outside the filter screen 16.
