Description
Technical Field
[0001] The utility model belongs to the technical field of guardrails, and in particular relates to a guardrail for municipal construction. Background Art
[0002] Municipal construction is an important part of municipal activities. It is the execution stage of planning and design. It is the construction of various public facilities and undertakings hosted by the city government according to the overall deployment of municipal planning, such as roads, drainage, bridges, etc. The purpose is to prosper the urban economy, facilitate the production and living environment of citizens, and promote the development of the city's material and spiritual civilization. In order to isolate the construction area from pedestrians during municipal construction, guardrails are needed.
[0003] During municipal construction, impact drills or excavator breaker hammers are used to dig cement roads. When the impact drills or excavator breaker hammers are operating, gravel will fly outwards. The height of the existing guardrails is fixed, and the height of the guardrails cannot be increased, so the gravel cannot be well protected. In particular, the kinetic energy of the excavator breaker hammer is large, and the gravel flies high, which can easily splash and injure passers-by. Therefore, a technical measure is proposed to solve the problem that the height of the guardrails under the existing technology is fixed, and the height of the guardrails cannot be increased, so the gravel cannot be well protected, and the gravel can easily splash and injure passers-by. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a guardrail for municipal construction, aiming to solve the problem that the height of the guardrail in the prior art is fixed and the height of the guardrail cannot be increased, thereby failing to provide good protection against gravel, and gravel is easily splashed and injures passers-by.
[0006] (2) Technical solution
[0007] In order to solve the above technical problems, the utility model provides a municipal construction guardrail, including a base, which has two groups. Fixed guardrails are installed on the upper part of the two groups of bases, and movable guardrails are movably connected to the upper part of the fixed guardrails. The movable guardrails and fixed guardrails are installed with baffles, and sponges are installed on the surface of the baffles. Two groups of limit grooves are opened on the upper side of the movable guardrails and fixed guardrails, and limit components are installed at the limit grooves. Thanks to the arrangement of fixed guardrails, movable guardrails, limit components, plug plates, slots, sponges and baffles, it is convenient to install movable guardrails according to the splash height of gravel, thereby having a good interception and protection effect on gravel, preventing gravel from splashing and injuring passers-by, and improving the safety of construction operations.
[0008] Furthermore, two groups of symmetrically distributed load-bearing plates are connected between the bases, and the lower parts of the load-bearing plates are close to the ground.
[0009] Furthermore, slots are provided on the upper parts of the movable guardrail and the fixed guardrail, a plug board is installed on the lower part of the movable guardrail, a plug hole is provided at the center of the plug board, and the plug board fits the slot card.
[0010] Furthermore, the limiting assembly includes a pressing plate, which is circular in design. A push rod is connected to the side of the pressing plate facing the sponge, and two sets of symmetrically distributed limiting rods are installed on the push rod. Thanks to the setting of the limiting assembly, it is convenient to fix the movable guardrail and the fixed guardrail to prevent the movable guardrail from detaching from the fixed guardrail, thereby making the fixed guardrail and the movable guardrail tightly connected, improving the firmness of the connection, and the elastic connection operation is relatively simple.
[0011] Furthermore, the limiting rod, the pushing rod and the limiting groove are adapted to each other.

The pressing plate is pushed inward to drive the extrusion plate to move horizontally. The extrusion plate moves horizontally to compress the spring. The extrusion plate moves horizontally to drive the plug rod to retract from the slot. After the limit rod enters the limit slot, the pressing plate is rotated to drive the limit rod from a vertical state to a horizontal state. The pressing plate is released, and the limit rod is driven to press against the inner wall of the fixed guardrail under the rebound action of the spring. Then the plug plate at the bottom of the movable guardrail is aligned with the slot of the fixed guardrail and inserted. Then the pressing plate is rotated to drive the limit rod back to the vertical state. Under the rebound action of the spring, the plug rod is driven to insert into the jack to complete the installation of the movable guardrail. BRIEF DESCRIPTION OF THE DRAWINGS
