Problems solved by technology

[0002] At present, when carrying out municipal construction work, a certain number of guardrails need to be set up around the corresponding construction area to ensure the safety of the construction site. During the use of guardrails for municipal construction, they cannot provide suitable buffer protection for different collision forces, which in turn leads to poor protection for both sides of the collision, and when the external collision force is strong, the equipment is prone to the risk of falling

Embodiment 1

[0023] see figure 2 with Figure 5 , a guardrail for municipal construction with a collision buffer function, comprising a housing 1, the inner cavity of the housing 1 is movably connected with a buffer mechanism 2, the buffer mechanism 2 includes a sliding frame 21, and the upper and lower ends of the sliding frame 21 are rotatably connected with The running wheel and the front and rear sides of the running wheel are fixedly sleeved with rubber bladders, which communicate with the middle of the inner cavity of the sliding frame 21, so that the air inside the sliding frame 21 can be squeezed when the gear block 23 moves for buffering. Into the rubber bladder, so that it expands and contacts the inner wall of the housing 1 to increase friction and relieve the impact force. The right part of the inner cavity of the housing 1 is slidably inserted with a buffer column 22 extending to the edge of the sliding frame 21. The sliding frame 21 The middle part of the inner cavity is sl...

Embodiment 2

[0025] see Figure 2-Figure 4 , a guardrail for municipal construction with a collision buffer function, further comprising a stabilizing mechanism 3 movably connected to the right wall of the casing 1, the stabilizing mechanism 3 comprising a special-shaped frame 31, the upper end of the special-shaped frame 31 is close to the sliding frame 21 One side is provided with an inclined slope, so that the special-shaped frame 31 is squeezed when the sliding frame 21 moves to the right. The lower wall of the inner cavity of the special-shaped frame 31 is fixedly connected with a wedge-shaped column 32, and the side of the wedge-shaped column 32 close to the telescopic column 35 is designed. There is a right-angled surface, so that it is convenient to initially limit the telescopic column 35, so that the extension bar 33 cannot be ejected under the elastic force of the compression spring 34, and the bottom inner cavity of the housing 1 is slidably plugged with an extension bar extendi...

Embodiment 3

[0027] see Figure 1-Figure 5, a guardrail for municipal construction with a collision buffer function, comprising a housing 1, the inner cavity of the housing 1 is movably connected with a buffer mechanism 2, the buffer mechanism 2 includes a sliding frame 21, and the upper and lower ends of the sliding frame 21 are rotatably connected with The running wheel and the front and rear sides of the running wheel are fixedly sleeved with rubber bladders, which communicate with the middle of the inner cavity of the sliding frame 21, so that the air inside the sliding frame 21 can be squeezed when the gear block 23 moves for buffering. Into the rubber bladder, so that it expands and contacts the inner wall of the housing 1 to increase friction and relieve the impact force. The right part of the inner cavity of the housing 1 is slidably inserted with a buffer column 22 extending to the edge of the sliding frame 21. The sliding frame 21 The middle part of the inner cavity is slidingly ...

Abstract

The invention relates to the technical field of guardrails, and discloses a municipal construction guardrail with a collision buffering function, the municipal construction guardrail comprises a shell, an inner cavity of the shell is movably connected with a buffering mechanism, the buffering mechanism comprises a sliding frame, a buffering column extending to the edge of the sliding frame is slidably inserted into the right part of the inner cavity of the shell, symmetrical tooth blocks are slidably connected with the middle of the inner cavity of the sliding frame, and an abutting spring is fixedly connected between the tooth blocks. According to the municipal construction guardrail with the collision buffering function, the tooth blocks are pushed to compress and abut against the spring through deformation of a hinge frame, small-collision-force buffering can be carried out, large-collision-force effective buffering can be carried out in cooperation with the self-adaptive reverse acting force of a telescopic flow guide ring when a permanent magnet strip moves, a guide connecting pipe, a tooth-shaped rod and an extension strip are matched to automatically deform to support the shell in time, so that the protection effect on the two collision parties is effectively improved, and the stability performance of equipment operation is improved.

Description

technical field [0001] The invention relates to the technical field of guardrails, in particular to a guardrail for municipal construction with a collision buffering function. Background technique [0002] At present, when carrying out municipal construction work, a certain number of guardrails need to be set up on the periphery of the corresponding construction area to ensure the safety of the construction site. However, during the use of general municipal construction guardrails with collision buffering functions, they cannot target different The collision force provides proper buffer protection, which in turn leads to poor protection for both sides of the collision, and when the external collision force is strong, the equipment is prone to the risk of tipping over. [0003] Aiming at the deficiencies of the prior art, the present invention provides a guardrail for municipal construction with a collision buffer function, which has the advantages of effectively improving th...
