Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction, and more specifically to a safety protection device for bridge construction. Background Technology

[0002] With the rapid development of modern industry, road and bridge construction has also seen many applications. However, existing road guardrails are large in size, have limited interception effect, and are expensive to manufacture. For construction site interception and protection, large-scale conventional guardrails are not necessary; they serve more as warnings.

[0003] For example, CN222276401U discloses a movable road construction safety guardrail, belonging to the field of guardrails. This guardrail includes a first baffle, a second baffle, and a third baffle. The first and third baffles are each connected to a support rod, which is connected to a triangular support frame. The first and second baffles are connected by hinges. Both the first and second baffles have mounting grooves. The first baffle is rotatably connected to a limit rod located inside the mounting groove. The second baffle is connected to a locking frame with a locking groove, and the limit rod cooperates with the locking groove. The connection method between the second and third baffles is the same as the connection method between the second and first baffles. This technical solution facilitates quick folding of the baffles, saves storage space, and facilitates the storage and transportation of the guardrail. It can be quickly unfolded, is easy to install, and the folding is completed by simply rotating the limit rod. The structure is simple and the operation is convenient. However, the folding guardrail described in this utility model has a relatively limited function, only suitable for localized road and bridge protection, and the overall cost is still relatively high. For example, CN221703392U discloses a safety fence for road construction. This utility model relates to the field of safety fence technology, including a fence body suitable for road construction safety protection. The fence body includes a left-side post, a right-side post on the right side of the left-side post, and counterweights fixedly installed at the bottom of both the left and right-side posts. Adjustment units are located on the inner sides of the left and right-side posts, and connecting units are located on the outer sides. This utility model, by incorporating a telescopic fence, allows for changing its length, facilitating adjustment as needed and improving ease of use and flexibility. During adjustment, the piston rod moves at both ends within sleeves one and two, limiting the adjustment and preventing misalignment. Support legs engage with the bottom of sleeves one and two for support, improving the fence's stability. However, the folding safety fence described in this utility model has a relatively limited function, only suitable for localized road and bridge protection, and its overall cost is relatively high.

[0028] This utility model discloses a bridge construction safety protection device, the advantages of which are as follows: Existing road guardrails are large in size and have high manufacturing costs, and fixed construction will damage the road surface. Long road and bridge sections require a large number of assembled guardrails, which are time-consuming and labor-intensive in both transportation and construction. This utility model provides a retractable guardrail device, which provides a road and bridge protection device with a small volume and large working environment by utilizing the excellent rollability of wire mesh. This device takes the protective base station 1 as the starting base station, and fixes the fixed base A102 to the ground by drilling and expansion bolts. The motor A105 is powered by an external power supply or an internal battery. Of course, the power system of the device is universal in the market and is a common structure, so it will not be described in detail in this article. Working principle: When motor A105 starts, its output shaft drives worm gear 107 to rotate. Worm gear 107 drives wire mesh assembly A109 to rotate via worm wheel 108. Wire mesh assembly A109 consists of a drum for storing wire mesh and the wire mesh itself. Each end of the wire mesh drum has a shaft, which is rotatably connected to shaft seat B117 and shaft seat E129, respectively. When wire mesh assembly A109 rotates counterclockwise, the wire mesh extends outwards, and during this extension, it is transported along transport shaft 132 and roller assembly 133. Transport shaft 132 rotates as the wire mesh extends. Roller assembly 133 is a component consisting of two sets of shafts and a fixed bracket. The wire mesh passes between the two sets of rolling shafts in roller assembly 133, serving to position and transport the wire mesh. Function: If it is necessary to adjust the distance between the transport shaft cylinder 132 and the roller assembly 133 to make the wire mesh extend outward more smoothly, the electromagnetic bars A112 and B123 are activated simultaneously. When the output shaft of electromagnetic bar A112 extends outward, it drives the pressure rod assembly A114 to rotate along the pressure rod shaft seat A115 via shaft A113. When the pressure rod shaft seat A115 rotates, it drives the crankshaft 121 to rotate along the shaft seats C119 and D120 via pressure rod A116. When the pressure rod assembly A114 rotates, it drives the pressure rod A116 to work, which plays a role in stabilizing and reinforcing the structure. When electromagnetic bar B123 is activated, its output shaft drives the pressure rod assembly B125 to rotate along the pressure rod shaft seat B126 via shaft B124. When assembly B125 rotates, it drives crankshaft 121 to rotate via pressure rod B127. The rotation of pressure rod assembly B125 also drives pressure rod B127, stabilizing and reinforcing the structure. Simultaneously, the rotation of pressure rod assembly A114 and pressure rod assembly B125 drives transport shaft cylinder 132 to slide along support arm A111 and support arm B128. When motor A105 starts, the operator moves drive base station 2 backward. Drive base station 2 can have its fixed base B202 replaced with a set of casters for flexible relocation. Specific modifications or expansions need to be made based on the actual site conditions. When drive base station 2 moves, the wire mesh assembly A109 in protective base station 1 is pulled outward to straighten. (Note: The last sentence appears to be incomplete and possibly refers to a different feature.)The wire mesh assembly A109 in protective base station 1 and the wire mesh assembly B211 in drive base station 2 are the same component. The wire mesh assembly connects both protective base station 1 and drive base station 2. The wire mesh assembly A109 in protective base station 1 is mainly responsible for winding and extending outwards, while the wire mesh assembly B211 in drive base station 2 is responsible for partial winding and straightening the wire mesh extending from the wire mesh assembly A109. If it is necessary to wind up the wire mesh assembly B211 in drive base station 2, the handle 213 is rotated reciprocally. When the handle 213 rotates along the shaft bracket B210, it is constrained by the tension spring 215. Pawls A214 and B216 synchronously drive ratchet 212 to rotate. As ratchet 212 rotates, it drives wire mesh assembly B211 to rotate, beginning the winding of the outer wire mesh until it is taut. If the wire mesh extends too far, it can be fixed to the ground and bound with steel structure columns. By installing steel structure columns at each node of the extended wire mesh, a safety protection device composed of wire mesh is formed. This device provides basic safety protection, and the expandable steel structure columns and universal pulleys enhance its practicality, better meeting the protection needs of various complex construction environments.

[0029] Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples mentioned above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model are also within the protection scope of this utility model.
