Description

Technical Field

[0001] The utility model belongs to the technical field of mining protection fences, in particular to a safety protection fence for mining. Background Art

[0002] Mining refers to the extraction of naturally occurring minerals such as solids (such as coal and minerals), liquids (such as crude oil) or gases (such as natural gas). During mining, safety fences need to be laid around the mine to prevent outsiders from entering the mine and prevent accidents.

[0003] According to Chinese patent CN107605236A, a safety guardrail for mining is proposed. In the device, the installation of the cross bar is facilitated by the setting of the clamping block, and the ears on the cross bar and the column facilitate the installation of the protective wire mesh. The setting of multiple columns, cross bars and clamping blocks can splice multiple protective wire meshes to widen the protection range.

[0004] Although the device can widen the protective width of the guardrail, when installed at a mine site for protection, the device cannot effectively protect both sides of the guardrail, thereby reducing the protective effect of the device. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model aims to provide a safety guardrail for mining, which can effectively protect both sides of the guardrail.

[0006] The utility model is realized by adopting the following technical solutions:

[0007] A safety guardrail for mining includes two vertical plates and a retractable guardrail fixedly installed between the two vertical plates; the vertical plates are equipped with an adjustment assembly, the adjustment assembly includes a stabilizing mechanism fixedly connected to the vertical plates for stabilizing the vertical plates, the vertical plates are equipped with an adjustment mechanism, and the adjustment mechanism is rotatably connected to a rotating guardrail.

[0008] When in use, first transfer the guardrail to the position that needs protection, then move the two vertical plates to a suitable distance (that is, stretch the telescopic guardrail to a suitable position), fix the vertical plates to the ground through a stabilizing mechanism, and finally rotate the guardrail to a suitable angle. The utility model also effectively protects both sides of the mine, improving the use efficiency of the guardrail.

[0009] Further preferably, the retractable guardrail can be realized in the following way: the retractable guardrail includes a fixed guardrail with a hollow structure and a stretchable guardrail sleeved inside the fixed guardrail, a row of equidistant slots are provided on the top of the fixed guardrail, a connecting spring is fixedly installed on the top of the stretchable guardrail, a card block is fixedly installed on the other end of the connecting spring, the card block is slidably connected to the card slot of the retractable guardrail, one side of the fixed guardrail is fixedly connected to one side of one vertical plate, and one side of the stretchable guardrail is fixedly connected to one side of the other vertical plate.

[0010] When in use, the operator can press the card block, and the card block will be disengaged from the limit of the retractable guardrail under the action of the connecting spring. Then the operator can pull the stretch guardrail to a suitable length, so as to adjust the stretch length of the guardrail when protecting the mine. After the length of the stretch guardrail is adjusted, loosening the card block connecting spring will make the card block fit with the corresponding card slot, so as to complete the limit of the adjusted stretch guardrail, that is, the stretch guardrail and the retractable guardrail cannot move relative to each other. At this time, fix the other vertical plate to the ground through a stabilizing mechanism, and rotate the guardrail to a suitable angle. The utility model effectively protects both sides of the mine, thereby improving the efficiency of the use of the guardrail.

[0011] Further preferably, the stabilizing mechanism can be adopted in the following ways: the stabilizing mechanism includes a stabilizing cross plate fixedly connected to the bottom of the vertical plate, the stabilizing cross plate is provided with a threaded hole, the internal thread of the threaded hole is connected to a screw, an adjusting handle is fixedly installed on the top of the screw, and the bottom of the screw is rotatably connected to a conical insertion block.

[0012] By setting up a stabilizing mechanism, when the mine needs to be protected, the operator can transfer the guardrail to the position so that the bottom of the stabilizing cross plate fits with the ground, and then rotate the adjusting handle to rotate the screw. When the screw rotates, it will move downward with the conical insert block. When the conical insert block is inserted into the ground, the guardrail can be fixed to improve the stability of the guardrail during use.

[0013] Further preferably, the adjustment mechanism can be adopted in the following ways: the adjustment mechanism includes a side block fixedly connected to the top of the front side surface of the vertical plate, the lower surface of the side block is rotatably connected to a vertical rotating rod via a bearing, a rotating guardrail is fixedly installed on the outer periphery of the rotating rod, a gear is fixedly installed on the outer periphery of the bottom of the rotating rod, and the lower outer periphery of the gear installed on the bottom of the rotating rod is rotatably connected to the top of the stabilizing cross plate via a bearing.

[0014] The L-shaped clamping rod includes a first clamping rod and a second clamping rod, the first clamping rod and the second clamping rod are vertically arranged, the shape of the end of the first clamping rod is the same as the gear tooth shape, and is clamped between two teeth of the gear, the first clamping rod is slidably connected to a limiting sleeve, a side plate is fixedly installed between the rear side wall of the limiting sleeve and the vertical plate, a return spring is fixedly installed on the outer side wall of the side plate, and the other end of the return spring is fixedly connected to the second clamping rod.

[0015] By setting up the adjustment mechanism, when the mine needs to be protected by the guardrail, the operator can pull the second clamping rod to disengage the first clamping rod from the limit on the gear, and the operator can rotate the rotating guardrail to adjust the protection angle on both sides. When the rotation angle of the rotating guardrail is adjusted, the operator can release the first clamping rod, and the first clamping rod will be reset under the reaction of the reset spring, so that the first clamping rod is inserted into the side wall of the gear, thereby limiting the rotating guardrail with the adjusted rotation angle to complete the protection of both sides of the mine.

[0016] Further preferably, in order to provide secondary reinforcement for the guardrail, a telescopic rod is further included, the two vertical plates are of equal size, and the telescopic rod is arranged on a side close to the ground between the two vertical plates.

[0017] The utility model provides a safety fence for mining. The safety fence for mining has the following beneficial effects:

[0018] (1) The mining safety fence is provided with a stabilizing mechanism. When the mine needs to be protected, the operator can move the fence to a position so that the bottom of the stabilizing horizontal plate is in contact with the ground. Then, the operator can rotate the adjusting handle to rotate the screw. When the screw rotates, the conical insert block moves downward. When the conical insert block is inserted into the ground, the device can be fixed to improve the stability of the device during use.

[0019] (2) The mining safety guardrail is provided with an adjustment mechanism. When it is necessary to protect the mine through the device, the operator can press the card block. Under the action of the connecting spring, the card block will be separated from the limit of the retractable guardrail. The operator can then pull the stretch guardrail to a suitable length, thereby adjusting the stretch length of the guardrail when protecting the mine. After the length of the stretch guardrail is adjusted, the card block will fit into the corresponding card slot, thereby completing the limit of the adjusted stretch guardrail.
