Description

Technical Field

[0001] The utility model relates to the field of road and bridge construction, and particularly relates to a safety protection fence for road and bridge construction. Background Art

[0002] When constructing roads and bridges, it is necessary to install safety protection fences. However, it is difficult to install protection fences on the steel beams at the edges of bridges. The traditional mechanical bolt connection method not only has low efficiency but also insufficient firmness. At the same time, there is a certain danger during edge installation, and the direct welding method has the problem of inconvenient subsequent removal. In addition, most traditional protection fences have fixed sizes and cannot be adjusted in length according to the on-site size, which is inconvenient to use and also results in a large storage volume, making transportation and storage inconvenient. Therefore, the utility model provides a safety protection fence for road and bridge construction. Content of the Utility Model

[0003] In order to overcome the defects in the above-mentioned prior art, the utility model provides a safety protection fence for road and bridge construction. By setting the oblique telescopic rod, the horizontal telescopic rod, and the retractable protection net, the overall length of the fence can be adjusted according to the actual scenario, and it is also convenient for storage and transportation. By directly welding the disposable welding plate to the steel beam, the installation of the bottom plate can be achieved quickly, safely, and firmly. When disassembling, only need to remove the bottom plate from the welding plate.

[0004] Technical Solution

[0005] A safety protection fence for road and bridge construction, including a bottom plate, a welding plate is inserted outside the bottom plate, two mounting rods are fixedly arranged on the upper side of the bottom plate, sleeves are inserted on the mounting rods, two mounting parts are fixedly arranged on the sleeves, and an oblique telescopic rod is connected between two obliquely opposite mounting parts.

[0006] Furthermore, a protection net capable of horizontal expansion and contraction is also arranged between the sleeves.

[0007] Furthermore, the oblique telescopic rod is hinged to the mounting part.

[0008] Furthermore, horizontal telescopic rods fixedly arranged between the sleeves are also arranged on the upper and lower sides of the protection net.

[0009] Furthermore, a fixing cover capable of being stuck on the upper end of the mounting rod is arranged at the upper end of the sleeve.

[0010] Furthermore, the bottom plate and the welding plate are fixed by bolts.

[0011] Advantageous Effects

[0012] Compared with the prior art, the utility model has the following beneficial effects: the overall length of the fence can be adjusted according to the actual scenario through the settings of the diagonal telescopic rod, the horizontal telescopic rod, and the retractable protective net, and it is also convenient for storage and transportation; by directly welding the disposable welding plate to the steel beam, the installation of the bottom plate can be achieved quickly, safely, and firmly. When disassembling, only need to remove the bottom plate from the welding plate, and structures such as the protective net and the sleeve can be reused. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic structural diagram of a safety protection fence for road and bridge construction of the present utility model.

[0014] REFERENCE NUMBERS IN THE DRAWINGS

[0015] Bottom plate 1, welding plate 2, bolt 3, diagonal telescopic rod 4, installation part 5, installation rod 6, sleeve 7, fixed cover 8, horizontal telescopic rod 9, protective net 10. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] To better illustrate and explain the content of the present utility model, the following will be described in conjunction with the drawings and embodiments:

[0017] There is Figure 1 As shown, the present utility model discloses a safety protection fence for road and bridge construction, including a bottom plate 1. A welding plate 2 is inserted into the outside of the bottom plate 1. Two installation rods 6 are fixedly arranged on the upper side of the bottom plate 1. A sleeve 7 is inserted into the installation rod 6. Two installation parts 5 are fixedly arranged on the sleeve 7. A diagonal telescopic rod 4 is connected between two diagonally opposite installation parts 5.

[0018] Furthermore, a protective net 10 capable of horizontal telescoping is also arranged between the sleeves 7.

[0019] Furthermore, the diagonal telescopic rod 4 is hinged to the installation part 5.

[0020] Furthermore, horizontal telescopic rods 9 fixedly arranged between the sleeves 7 are also arranged on the upper and lower sides of the protective net 10.

[0021] Furthermore, a fixed cover 8 capable of being stuck on the upper end of the installation rod 6 is arranged at the upper end of the sleeve 7.

[0022] Furthermore, the bottom plate 1 and the welding plate 2 are fixed by bolts 3.

[0023] Specifically, during installation, the bottom plate 1 is inserted into the welding plate 2 in the front-rear direction, and then fixed by bolts 3;

[0024] When the welding plate 2 is welded to the steel beam on the edge of the bridge, the installation of the bottom plate 1 can be achieved quickly, safely, and firmly;

[0025] Then, insert the sleeve 7 into the mounting rod 6 and then install the fixing cover 8 to achieve the installation and fixation of the safety protection fence;

[0026] Moreover, the lateral position of the sleeve 7 can be adjusted according to the actual length of the steel beam. When adjusting, directly stretch or contract the diagonal telescopic rod 4 and the lateral telescopic rod 9;

[0027] When storing, retract the diagonal telescopic rod 4 and the lateral telescopic rod 9 to the shortest length, so that it can be stored with the minimum volume.

[0028] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the technical solutions of the present invention have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of each embodiment of the present invention.
