Description

Technical Field

[0001] The present application relates to the technical field of telescopic guardrails, and specifically discloses a multi-functional telescopic guardrail for mining. Background Art

[0002] About telescopic guardrail: telescopic guardrail is a kind of device that protects and plays a certain warning role. This device is very mature. At present, telescopic guardrails with intelligent recognition and telescopic, and telescopic guardrails with electric telescopic have been developed. Regarding the existing telescopic guardrails, generally speaking, the existing telescopic guardrails are straight in and straight out. Since they are all in the form of hinges, the guardrails are made of hard materials. Therefore, the telescopic guardrails on the market can only be in a straight line;

[0003] Since the environment in which the telescopic guardrail is applicable is relatively simple and uncomplicated, this telescopic guardrail that can only be telescoped in a straight line is already competent. However, in mines, this traditional telescopic guardrail will have problems: first of all, in mines, there will be underground tunnels. The underground tunnels are a narrow space, and most of the underground tunnels are not only narrow but also irregular. For example, some underground tunnels need to be installed with telescopic guardrails on both sides, but the sides of such underground tunnels are irregular, some places are sunken, and some are protruding. If the underground tunnels are installed to avoid such irregular depressions and protrusions, the tunnels available for workers to pass will be even narrower. For this reason, the underground tunnels can only be installed to fit such irregular depressions and protrusions. Therefore, the inventor proposes a multi-function telescopic guardrail for mining. Utility Model Content

[0004] The utility model aims to solve the problem that the traditional telescopic guardrail cannot be elastically deformed.

[0005] In order to achieve the above purpose, the basic scheme of the utility model provides

The guardrail rod includes a main rod, springs fixed to both ends of the main rod and a secondary rod arranged at the end of the spring. The end of the secondary rod is provided with a hinge hole, and a pin is inserted into the hinge hole.

[0008] The principles and effects of this basic solution are:

[0009] 1. Compared with the existing technology, it has all the functions of the traditional telescopic guardrail and has advantages that the traditional telescopic guardrail does not have. It is suitable for installation on both sides of narrow underground tunnels.

[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0019] The figure marks in the drawings of the specification include: mounting frame 1, load-bearing plate 2, moving wheel 3, first hinge point 4, second hinge point 5, third hinge point 6, guardrail 7, mounting groove 8, mounting plate 10, screw 11, connecting rod 12, spring 13, auxiliary rod 14, hinge hole 15.

[0020] Implementation example Figure 1 , Figure 2 and Figure 3 As shown:

[0021] A multi-function telescopic guardrail for mining, comprising a symmetrically arranged mounting frame 1, a load-bearing plate 2 fixed to the bottom of the mounting frame 1, a first hinge point 4 and a second hinge point 5 are arranged in sequence on the inner side of the mounting frame 1, a plurality of cross-arranged guardrail bars 7 are arranged between the mounting frames 1, and the cross positions of the guardrail bars 7 are all hinged, such as Figure 1 As shown, the guardrail 7 is hinged at a plurality of third hinge points 6, and the guardrail 7 close to the mounting frame 1 is hinged to the first hinge point 4 and the second hinge point 5 respectively;

[0022] Specific: such as Figure 1 As shown, the first hinge point 4 and the second hinge point 5 are arranged vertically from top to bottom, and the load-bearing plate 2 is provided with a moving wheel 3 for moving the device. The moving wheel 3 is provided to change the installation position of the device, thereby improving the portability of the device;

[0023] like Figure 1 and Figure 2 As shown, the guardrail 7 is arranged in a fork-shaped structure, the inner wall of the mounting frame 1 is provided with a mounting groove 8, the first hinge point 4 and the second hinge point 5 are placed in their respective mounting grooves 8, both ends of the first hinge point 4 and the second hinge point 5 are fixedly connected with mounting plates 10, and the mounting plate 10 is provided with screws 11 which can be threadedly connected with the bottom of the mounting groove 8. The purpose here is: since the guardrail 7 can be elastically deformed, in order to avoid the collapse of the first hinge point 4 and the second hinge point 5, the screws 11 and the mounting groove 8 are arranged at the fine adjustment of the first hinge point 4 and the second hinge point 5, so that the first hinge point 4 and the second hinge point 5 are not easy to collapse;

[0024] like Figure 3 As shown, the first hinge point 4 and the second hinge point 5 are both slidably connected to the mounting frame 1, the guardrail rod 7 includes a main rod, a spring 13 fixedly connected to both ends of the main rod and a secondary rod 14 arranged at the end of the spring 13, and a hinge hole 15 is provided at the end of the secondary rod 14, and a pin is inserted into the hinge hole 15. The guardrail rod 7 is a metal rod, and the outer wall of the guardrail rod 7 is coated with red and white warning paint.

[0025] Specific implementation process:

[0026] In the first step, the device is installed underground, on both sides of the underground pedestrian lane, with the purpose of marking out the warning area to prevent workers from getting injured when passing through;

[0027] The second step is that due to the irregularities on both sides of the underground pedestrian lane, if the traditional telescopic guardrail is avoided for installation, the lane for people to pass through will be narrower. Therefore, this case makes certain improvements on the guardrail rod 7. The specific installation steps are as follows: install it close to both sides of the underground pedestrian lane. If the side wall is convex, due to the connection relationship between the spring 13, the main rod and the auxiliary rod 14, the guardrail rod 7 at this position can be elastically deformed, which will not affect the overall installation;

[0028] The third step is, if the side wall is concave, such as Figure 3 As shown, in this case, a connecting hole is opened at the center of the main rod, and a connecting rod 12 is inserted into the connecting hole. The connecting rod 12 passes through the main rod and directly hits the side wall, so that the concave position can be used well, thereby making the space in the middle for people to pass larger;

[0029] The fourth step is that since the guardrail 7 will undergo a certain elastic deformation, during installation, the first hinge point 4 and the second hinge point 5 should be installed according to the situation, and the positions of the first hinge point 4 and the second hinge point 5 should be changed by the screws 11 to avoid the first hinge point 4 and the second hinge point 5 from collapsing due to excessive elastic deformation.

[0030] The device solves the problem that the traditional telescopic guardrail cannot be elastically deformed.

[0031] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
