Description

Technical Field

[0001] The utility model belongs to the technical field of municipal roads, and particularly relates to a temporary safety protection device for municipal roads. Background Art

[0002] When municipal roads are under maintenance and construction, in order to avoid safety accidents, temporary protective devices need to be set up around the construction area. The usual protective device is an iron horse guardrail, which can be used to block the construction area.

[0003] At present, a Chinese patent with publication number CN218757135U and publication date March 28, 2023 discloses a stable iron horse, including a guardrail body and a support leg. The bottom of the guardrail body is fixedly connected with a cross-shaped connector, the bottom of the cross-shaped connector is rotatably connected with an internal threaded pipe joint, and the top of the support leg is fixedly connected with an external threaded pipe joint. The internal threaded pipe joint and the external threaded pipe joint are threadedly connected, so that the connection between the guardrail body and the support leg is detachable. The bottom of the support leg is threadedly connected with an adjustment foot, and the bottom of the adjustment foot is provided with a flange foot seat, so that the support height between the support foot and the ground can be adjusted, and the contact area between the support foot and the ground is increased, thereby increasing the stability of the placement of the iron horse. A connecting block and a mounting block are respectively provided on both sides of the guardrail body, and a retractor is installed on the mounting block. A webbing is pre-tightened and wound on the retractor. The end of the webbing is fixedly connected with a connecting rod, and a socket matching the connecting rod is provided on the connecting block.

[0004] When using iron horse guardrails, multiple iron horse guardrails are joined together at the sides to surround the construction area; however, when the construction area is large, the number of iron horse guardrails is required to be relatively large, and the transportation of multiple iron horse guardrails will cause a lot of trouble, and the transportation and procurement costs are also high. Utility Model Content

[0005] The utility model aims to provide a temporary safety protection device for municipal roads, so that the length of the guardrail can be changed according to actual needs.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: a temporary safety protection device for a municipal road, comprising a guardrail, the guardrail comprising a first tube body located on one side and in an inverted L shape, a second tube body located on the other side and in an inverted L shape, a first transverse tube located at the lower side of the first tube body, and a second transverse tube located at the lower side of the second tube body, a fixing plate is arranged between the first tube body and the first transverse tube, and between the second tube body and the second transverse tube, a cavity layer is arranged in the fixing plate, a connecting shaft is fixed in the upper and lower sides of the cavity layer, a coil spring with one end fixed to the connecting shaft is sleeved on the connecting shaft, an upper barrier strip with two ends respectively fixed to one end of the two coil springs away from the connecting shaft is arranged between the first tube body and the second tube body, a lower barrier strip with two ends respectively fixed to one end of the two coil springs away from the connecting shaft is arranged between the first transverse tube and the second transverse tube, and a limiting member for limiting the upper barrier strip or the lower barrier strip passing therethrough is arranged on the first tube body, the second tube body, the first transverse tube, and the second transverse tube.

[0007] The utility model is further configured as follows: the limit member includes a limit box arranged on the first tube body, the second tube body, the first cross tube and the second cross tube and for the upper barrier belt or the lower barrier belt to pass through, an internal threaded sleeve arranged on the limit box and communicated with the limit box, a threaded shaft threadedly connected to the internal threaded sleeve, and a rubber pressure block arranged at the end of the threaded shaft.

[0008] The utility model is further configured as follows: a vertical rod is arranged between the upper and lower limit boxes.

[0009] The utility model is further configured as follows: a first clamping sleeve for embedding the first tube body end is provided at the second tube body end, and a second clamping sleeve for embedding the first tube body end is provided at the second transverse tube end.

[0010] The utility model is further configured as follows: seat plates are provided at the lower ends of the first tube body and the second tube body, and rubber pads are bonded to the lower surfaces of both ends of the seat plates.

[0011] The utility model is further configured as follows: the surfaces of the upper barrier strip and the lower barrier strip are both coated with a reverse coating layer.

[0012] In summary, the utility model has the following beneficial effects:

[0013] 1. When the guardrail is in use, first cancel the limit of the upper barrier strip and the lower barrier strip by the limiter, then pull the first tube body and the second tube body toward the side away from each other, wherein the two coil springs on the upper side can unwind the upper barrier strip, and the two coil springs on the lower side can unwind the lower barrier strip, until the upper barrier strip and the lower barrier strip of the required length are unwound, and then use the limiter to limit the position of the upper barrier strip and the lower barrier strip, so that the guardrail can finally change its length according to actual needs;

[0014] When the guardrail is finished using and needs to be stored, the limiting function of the limiting member is cancelled, and then the elastic restoring force of the coil spring can reel in the upper barrier strip and the lower barrier strip, and at the same time, the first tube body and the second tube body can move toward a side close to each other, and the guardrail can be reduced to the shortest length, so as to facilitate the convenient storage of the guardrail;

[0015] 2. The rubber pressing block can be driven to move up and down in the limit box by rotating the threaded shaft. When the rubber pressing block moves in the limit box, the upper barrier belt or the lower barrier belt can be pressed against the inner wall of the limit box, and finally the upper barrier belt and the lower barrier belt can be limited. At the same time, when the rubber pressing block is moved in the opposite direction in the limit box, the limiting effect on the upper barrier belt or the lower barrier belt can be cancelled.

[0016] 3. By using the vertical rods set between the upper and lower limit boxes, the vertical rods can enhance the structural strength of the entire guardrail, making the guardrail structure more stable and reliable;

[0017] 4. When the guardrail is used and needs to be stored, the first tube body and the second tube body are moved toward the side close to each other so that the end of the first tube body is embedded in the first clamping sleeve, and the end of the first transverse tube is embedded in the second clamping sleeve. At this time, the first clamping sleeve can guide the docking of the first tube body and the second tube body, and the second clamping sleeve can guide the docking of the first transverse tube and the second transverse tube;

[0018] 5. The first tube body and the second tube body are supported on the ground by a seat plate, and rubber pads bonded to the lower surfaces of both ends of the seat plate are used to increase the friction between the rubber pads and the ground, thereby facilitating stable support of the seat plate on the ground;

[0019] 6. The reflective coating layer coated on the surface of the upper barrier strip and the lower barrier strip can reflect light at night, which is helpful to remind passing drivers and reduce the possibility of collision accidents. BRIEF DESCRIPTION OF THE DRAWINGS
