Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction technology, specifically to a road and bridge construction protection device that can prevent falls. Background Technology

[0002] Before the construction of road and bridge projects, a protective device is usually built to completely enclose the area around the construction site. This protective device can not only effectively isolate the construction area from the surrounding environment and mark the scope of the construction area, but also make the construction progress and construction area more standardized and systematic. It helps to manage and control the order of the construction site and plays a role in protecting the safety of surrounding residents, pedestrians and vehicles.

[0003] However, during road and bridge construction, the construction environment is often close to the edge of the road or bridge. Construction waste generated during the construction process can easily fall through the guardrails and into the area below the road or bridge. If the construction waste falls into the road or traffic area below the road or bridge, it will directly threaten the safety of passing vehicles and pedestrians. Drivers may not be able to react in time due to the sudden obstacle, causing traffic accidents. In view of this, we propose a road and bridge construction protection device that can prevent falls. Utility Model Content

[0004] The purpose of this invention is to provide a fall-prevention protective device for bridge and road construction, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fall-prevention safety device for bridge and road construction, comprising a guardrail, wherein a support frame is fixedly connected to the side wall of the guardrail, and a protective component is provided on the top end face of the guardrail, the protective component comprising:

[0006] An extension rod, wherein a limiting seat is fixedly connected to the side wall of the extension rod;

[0007] A receiving groove is formed on the side wall of the upright. A hinge rod is hinged to the inner wall of the receiving groove. A protective mesh is fixedly connected to the side wall of the hinge rod. A steel wire rope is fixedly connected to the side wall of the hinge rod.

[0008] The mounting block has a connecting frame sleeved on its side wall, and a roller is fixedly connected to the end face of the connecting frame.

[0009] Preferably, the extension rod is sleeved with the top of the guardrail, and the limiting seat is sleeved with the end face of the hinge rod. Through the sleeved connection between the limiting seat and the hinge rod, the hinge rod is retracted, so that the protective mesh fits snugly against the guardrail.

[0010] Preferably, the side wall of the support frame is hinged with a telescopic rod, and the end of the telescopic rod away from the support frame is hinged with a connector. The connector is fixed to the ground by expansion bolts to fix the position of the device.

[0011] Preferably, the mounting block is fixedly connected to the side wall of the upright, and four sets of rollers are provided, which are symmetrically arranged on both sides of the guardrail. Rotating the connecting frame makes the connecting frame contact the ground, which facilitates the movement of the device.

[0012] Preferably, the end of the wire rope away from the hinge rod is fixedly connected to the inner wall of the receiving groove, and the hinge rod is movably connected to the inner wall of the receiving groove. The wire rope increases the supporting force of the hinge rod on the protective mesh, enabling the protective mesh to block objects of greater mass.

[0013] Preferably, a support frame is rotatably connected to the outer wall of the upright, and a crossbar is fixedly connected to the outer wall of the limiting seat.

[0014] Preferably, the support frame has a semi-circular groove at the end away from the upright, and the inner wall of the semi-circular groove is movably connected to the outer wall of the crossbar.

[0015] Compared with the prior art, this utility model provides a fall-prevention safety device for bridge and road construction, which has the following beneficial effects:

[0016] 1. This fall-prevention bridge construction safety device, through its protective components and dense protective netting, prevents construction waste generated during the construction process from falling through the guardrails below the bridge. The waste cannot penetrate the guardrails, thus avoiding potential dangers to traffic or the environment below, enhancing safety, and reducing the occurrence of accidents. The dense protective netting increases the distance between pedestrians and the guardrails, keeping pedestrians away from the guardrails and preventing them from climbing over the guardrails due to poor visibility of the bridge surface, which could lead to a fall. By positioning the dense protective netting towards the edge of the bridge, even if a pedestrian or worker accidentally falls, the netting can still stop them, enhancing the protective effect and reducing the probability of a fall.

[0017] 2. This fall-prevention road and bridge construction safety device, through the installation of a support frame and crossbars, allows the semi-circular groove on the support frame to abut against the outer wall of the crossbars, thereby increasing the overall height of the guardrail. By increasing the height of the guardrail, pedestrians can see its existence more clearly, thus reducing the risk of misjudgment and climbing over it, and improving pedestrian safety.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a fall-prevention road and bridge construction safety device, including a guardrail 1, a support frame 2 fixedly connected to the side wall of the guardrail 1, a telescopic rod 4 hinged to the side wall of the support frame 2, a connector 5 hinged to the end of the telescopic rod 4 away from the support frame 2, and the connector 5 is fixed to the ground by expansion bolts to fix the position of the device. A protective component 3 is provided on the top end face of the guardrail 1, and the protective component 3 includes an extension rod 301, a limiting seat 302, a receiving groove 303, a hinge rod 304, a protective mesh 305, a steel wire rope 306, a mounting block 307, a connecting frame 308, and a roller 309.

[0025] In one embodiment of this utility model, the side wall of the extension rod 301 is fixedly connected to the limiting seat 302, the extension rod 301 is sleeved with the top of the guardrail 1, and the limiting seat 302 is sleeved with the end face of the hinge rod 304. Through the sleeved connection between the limiting seat 302 and the hinge rod 304, the hinge rod 304 is retracted, so that the protective mesh 305 is in close contact with the guardrail 1.

[0026] The receiving groove 303 is formed on the side wall of the upright 2. The inner wall of the receiving groove 303 is hinged to a hinge rod 304. A protective mesh 305 is fixedly connected to the side wall of the hinge rod 304. A steel wire rope 306 is fixedly connected to the side wall of the hinge rod 304. The end of the steel wire rope 306 away from the hinge rod 304 is fixedly connected to the inner wall of the receiving groove 303. The hinge rod 304 is movably connected to the inner wall of the receiving groove 303. The steel wire rope 306 increases the supporting force of the hinge rod 304 on the protective mesh 305, so that the protective mesh 305 can block objects of greater mass.

[0027] A connecting frame 308 is sleeved on the side wall of the mounting block 307. A roller 309 is fixedly connected to the end face of the connecting frame 308. The mounting block 307 is fixedly connected to the side wall of the upright frame 2. There are four sets of rollers 309. The four sets of rollers 309 are symmetrically arranged on both sides of the guardrail 1. Rotating the connecting frame 308 will make the connecting frame 308 contact the ground, which facilitates the movement of the device.

[0028] The limiting seat 302 is sleeved with the hinge rod 304, thereby closing the hinge rod 304 and making the protective net 305 fit against the guardrail 1. The protective net 305 prevents construction waste generated during construction from falling below the road and bridge through the guardrail 1. The waste cannot penetrate the guardrail 1, thereby avoiding potential dangers to traffic or the environment below, enhancing safety, and reducing the occurrence of accidents.

[0029] Pulling the extension rod 301 upwards causes the limit seat 302 to disengage from the hinge rod 304, allowing the hinge rod 304 to rotate and move the protective net 305 away from the guardrail 1. The angle between the protective net 305 and the guardrail 1 is 45°. At night, the protective net 305 increases the distance between pedestrians and the guardrail 1, keeping pedestrians away from the guardrail 1 and preventing pedestrians from climbing over the guardrail due to poor visibility of the bridge surface, which could lead to a fall. The steel wire rope 306 allows the protective net 305 to be oriented towards the edge of the bridge. The steel wire rope 306 also increases the supporting force of the hinge rod 304 on the protective net 305, enabling the protective net 305 to support the weight of an adult. Even if a pedestrian or worker accidentally falls, the protective net 305 can stop them, enhancing the protective effect and reducing the probability of a fall.

[0030] In addition, a support frame 6 is rotatably connected to the outer wall of the upright 2, and a crossbar 7 is fixedly connected to the outer wall of the limiting seat 302. A semi-circular groove is opened at the end of the support frame 6 away from the upright 2. The inner wall of the semi-circular groove is movably connected to the outer wall of the crossbar 7. When the extension rod 301 is lifted upward, the support frame 6 is rotated so that the semi-circular groove on the support frame 6 abuts against the outer wall of the crossbar 7, thereby increasing the overall height of the guardrail 1. By increasing the height of the guardrail 1, pedestrians can see the presence of the guardrail 1 more clearly, thereby reducing the risk of misjudgment and climbing over, and improving pedestrian safety.

[0031] In this utility model, during use, the protective mesh 305 prevents construction waste generated during construction from falling below the road / bridge through the guardrail 1. The waste cannot penetrate the guardrail 1, thus avoiding potential dangers to traffic or the environment below, enhancing safety, and reducing the occurrence of accidents. Pulling the extension rod 301 upwards causes the limiting seat 302 to disengage from the hinge rod 304, and the hinge rod 304 rotates, moving the protective mesh 305 away from the guardrail 1. The angle between the protective mesh 305 and the guardrail 1 is 45°. At night, the protective mesh 305... Increasing the distance between pedestrians and guardrail 1 keeps pedestrians away from guardrail 1, preventing pedestrians from climbing over the guardrail due to poor visibility of the bridge surface, which could lead to a fall from the bridge. By installing steel wire rope 306, the protective net 305 can be oriented towards the edge of the road and bridge. The steel wire rope 306 increases the supporting force of the hinged rod 304 on the protective net 305, allowing the protective net 305 to bear the weight of an adult. Even if a pedestrian or worker accidentally falls, the protective net 305 can stop them, enhancing the protective effect and reducing the probability of a fall from the bridge.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
