Description

Technical Field

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

[0002] A railway station yard is centered around the station, with entrance and exit signals on both sides of the up and down lines. The area inside the entrance signals on both sides is the station yard. During the construction of the station yard, protection measures need to be taken on the outside of the station yard to prevent pedestrians from accidentally entering the construction area and causing safety accidents.

[0003] A search revealed that utility model patent CN219261963U discloses a railway construction guardrail, comprising a guardrail body with symmetrically fixed plates at the bottom. Grooves are formed on both sides of the guardrail body, and mounting holes are provided inside each groove. Multiple through holes are provided at the bottom of each fixed plate, and an assembly mechanism is provided at the bottom of the fixed plate. This assembly mechanism is used for assembling and fixing multiple guardrail bodies. The assembly mechanism includes a box, with a horizontal plate fixedly connected to the bottom of the box and a top cover. An assembly plate is located inside each groove. This design, through the assembly mechanism, eliminates the need for concrete pouring during guardrail body installation. Instead, the overall mass of the box, buried underground, ensures good stability and anti-overturning capability after installation. Furthermore, it reduces the workload of disassembling the guardrail body after subsequent construction.

[0004] However, the aforementioned patents have the following shortcomings: the guardrail body is large and not easy to shrink, making it inconvenient to transport and store; in addition, the guardrail can only prevent pedestrians from accidentally entering, but it is not convenient to block dust generated during construction, and the dust can easily drift through the guardrail to the outside of the station construction area. To address these issues, we propose a safety protection device for station construction. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a safety protection device for station construction.

[0006] To solve the above problems, the present invention adopts the following technical solution:

The end of the pin is movably sleeved to the outside of the first connecting column. A sliding column is fixedly connected to the side of the pressing block. The end of the sliding column extends through the sliding groove to the outside of the first connecting column and is fixedly connected to a lever block.

[0010] As a preferred embodiment of this utility model, the bottom surfaces of the first column and the second column are both fixedly connected to mounting bases, and mounting holes are provided at both ends of the mounting bases.

[0011] In a preferred embodiment of this utility model, the side of the first sliding column is in contact with the inner wall of the first sliding groove, and the side of the second sliding column is in contact with the inner wall of the second sliding groove.

[0012] In a preferred embodiment of this utility model, the distance between the two first connecting posts and the height of the second connecting post are equal, and the inner diameter of the insertion hole and the outer diameter of the pin are equal.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) In this utility model, the first sliding column can slide in the first sliding groove and the second sliding column can slide in the second sliding groove, thereby driving the two pulling rods to rotate around the connecting shaft, which can drive the first column and the second column to move away from each other or move closer to each other, so as to reduce the overall volume of the device during transportation, and the first column and the second column can be unfolded for use during protection, which is practical.

[0015] (2) In this utility model, when the first column and the second column protect the construction site of the station, the hook is pulled to release the shielding cloth on the winding drum, so that the hook and the fixing hook on the second column are connected. At this time, the shielding is arranged between the first column and the second column, thereby using the shielding cloth to prevent dust from drifting to the outside of the station construction area, thus improving the working quality of the station construction safety protection device.

[0031] In this embodiment, the hook 19 and the fixing hook 13 can be connected to cover the shielding cloth 18 between the first column 1 and the second column 2, so as to block the dust.

[0032] For details, please refer to Figure 1 , Figure 2 and Figure 7 The connecting mechanism 15 includes two first connecting posts 21 fixedly connected to the end face of the first column 1. The inside of the first connecting post 21 is provided with a telescopic groove 22, and the side of the first connecting post 21 is provided with a moving groove 24. A spring 23 is fixedly connected to the inner wall of the telescopic groove 22. A pressing block 25 is fixedly connected to the end of the spring 23.

[0040] Working principle: In use, firstly, pull the first column 1 and the second column 2 away from each other, causing the first sliding column 5 to slide in the inner cavity of the first sliding groove 3, and simultaneously causing the second sliding column 6 to slide in the inner cavity of the second sliding groove 4. This allows the two pulling rods 7 to rotate around the connecting shaft 8, thereby adjusting the distance between the first column 1 and the second column 2. Then, place the mounting base 29 at the bottom of the first column 1 and the second column 2 on the ground, and fix the first column 1 and the second column 2 to the outside of the construction site using screws and mounting holes 30. Then, pull the hook 19 to release the shielding cloth 18 on the winding drum 17, so that the hook 19 is connected to the fixing hook 13 on the second column 2. At this time, the shielding cloth 18 is placed between the first column 1 and the second column 2, so as to prevent dust. Finally, the first column 1 and the second column 2 of the multiple protective devices are connected end to end, so that the second connecting column 9 is inserted into the inside of the two first connecting columns 21. The spring force of the spring 23 drives the pin 26 to be inserted into the socket 10 for fixing, so as to connect the multiple protective devices.

[0041] After using the protective device, remove the hook 19 from the fixed hook 13, turn the knob 20 to rotate the winding drum 17, and wind up the shielding cloth 18 through the winding drum 17 to store the released shielding cloth 18. In addition, push the first column 1 and the second column 2 closer to each other. At this time, the two pulling rods 7 move crosswise to reduce the size of the device, making it easier to store and transport.
