Description

Technical Field

[0001] The utility model relates to the technical field of safety protection sheds, in particular to a safety protection shed for a coal mine wellhead. Background Art

[0002] Coal mine shaft mouth safety protection shed is usually installed at the entrance of the coal mine to protect miners from adverse weather conditions when entering or leaving the mine, such as wind, rain, snow, high temperature, etc. At the same time, gravel is prone to rolling at the mine shaft mouth, and the use of a safety protection shed can fully protect the operating personnel.

[0003] However, under the current technical level, mine entrance safety protection sheds are usually installed by on-site lap jointing, which not only significantly prolongs the installation construction time, but also has a significant impact on the miners' access, thus affecting the production operations of the entire mine. Especially under severe weather conditions, such as strong winds and heavy snow, such existing safety protection sheds are often unable to withstand the huge wind loads and snow loads, causing the structure of the safety protection shed to deform or even cause serious damage, thereby increasing the cost of maintenance and replacement, which is not conducive to the economic benefits of the mine. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the safety protection shed at the mine shaft entrance in the prior art is mostly installed by on-site overlapping, and the overall installation and construction time is long. The long installation and construction time will affect the miners' work in and out of the shaft, delaying the miners' production operations. At the same time, the existing safety protection shed will be subjected to heavy wind loads and snow loads in strong winds and heavy snow weather, resulting in deformation of the safety protection shed and even damage. A safety protection shed for the mine shaft entrance of a coal mine is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a safety protection shed for a coal mine shaft entrance, comprising an adjusting installation mechanism, a protection mechanism is installed on the upper part of the adjusting installation mechanism, the adjusting installation mechanism comprises an embedded base, a first adjusting screw rod and a second adjusting screw rod, a first slide rail is fixedly connected to the upper part of the embedded base, a first slider is slidably connected inside the first slide rail, the first adjusting screw rod is rotatably connected to the first slide rail, and the first adjusting screw rod is threadedly connected to the first slider, a second slide rail is fixedly connected to the upper part of the first slider, a second slider is slidably connected inside the second slide rail, the second adjusting screw rod is rotatably connected to the second slide rail, and the second adjusting screw rod is threadedly connected to the second slider, a mounting base is fixedly connected to the upper part of the second slider, and a support rod is inserted inside the mounting base;

[0006] The protection mechanism includes a first mounting frame and a third slide rail, the first mounting frame is fixedly connected to the second mounting frame on the upper portion, the second mounting frame is fixedly connected to the protection shed on the upper portion, the first mounting frame is fixedly connected to the third sliding block on the bottom portion, the third sliding rail is slidably connected to the third sliding block, and the third sliding rail is fixedly connected to a connecting shell on the bottom portion, a telescopic rod is fixedly connected to the inside of the connecting shell, a connecting plate is fixedly connected to the bottom of the telescopic rod, a second spring is arranged on the surface of the telescopic rod, one end of the second spring is fixedly connected to the connecting shell, and the other end of the second spring is fixedly connected to the connecting plate, the bottom of the connecting plate is fixedly connected to a connecting rod, and the bottom of the connecting rod is fixedly connected to a supporting rod.

[0007] Preferably, a fixing bolt is inserted into the surface of the mounting base, the fixing bolt is inserted into the support rod, and one end of the fixing bolt is threadedly connected with a fixing nut.

[0008] Preferably, a limit rod is fixedly connected inside the third slide rail, the limit rod is slidably connected to the third slider, and a first spring is arranged on the surface of the limit rod, one end of the first spring is fixedly connected to the third slide rail, and the other end of the first spring is fixedly connected to the third slider.

[0009] Preferably, a limiting groove is provided on the surface of the connecting rod, a limiting block is fixedly connected inside the connecting shell, the limiting block is located inside the limiting groove and is slidably connected to the connecting rod, and a scale groove is provided on one side of the connecting rod.

[0010] Preferably, a fixing box is fixedly connected to the surface of the first mounting frame, a ventilator is installed at the bottom of the fixing box, and an electric heating pipe is installed inside the fixing box.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, the embedded base is embedded in the positioning position of the mine wellhead, and then the support rod and the protective mechanism on its upper part are hoisted as a whole by using a crane, and the support rod is plugged into the mounting base, so that the installation can be completed as a whole, which is convenient for the overall rapid construction and avoids affecting the normal production operation of the mine due to the installation of the protective mechanism. When the protective mechanism is hoisted, the first adjusting screw rod is driven to slide along the inside of the first slide rail by rotating the first adjusting screw rod, so as to adjust the lateral position of the mounting base, and the second adjusting screw rod is driven to slide along the second slide rail by rotating the second adjusting screw rod, so as to adjust the longitudinal position of the mounting base.

[0013] 2. In the utility model, during the use of the protective mechanism, the protective shed body is used to block external falling objects to prevent falling objects from hitting people, and at the same time, rain and snow are shielded. When strong winds blow to both sides of the protective shed body, the wind load on the protective shed body will be transmitted to the third slider through the second mounting frame and the first mounting frame. At this time, the third slider will slide along the inside of the third slide rail, and at the same time drive the first spring to perform telescopic deformation. The wind load is reversely offset by the elastic force of the first spring, and the force on the protective shed body is reduced, thereby improving the stability of the protective mechanism during use;

[0014] 3. In the utility model, when it snows outside, after the snow accumulates on the surface of the protective shed, the snow load on the protective shed will gradually increase. At this time, the connecting shell drives the limit block to slide downward along the connecting rod and the limit groove respectively. When the scale groove is blocked by the connecting shell, the snow load on the surface of the protective shed is too large. At this time, the electric heating tube and the ventilator are turned on, and the heat generated by the electric heating tube is blown to the lower part of the protective shed through the ventilator. By heating the lower part of the protective shed, the snow on its surface melts quickly, reducing the snow load on the protective shed, avoiding the collapse of the protective shed, and improving the safety of the protective mechanism.

[0032] The effect achieved by the entire embodiment is that during use of the protection mechanism 2, the protection shed body 23 is used to block external falling objects to prevent falling objects from hitting people, and at the same time, rain and snow are shielded. When strong winds blow toward both sides of the protection shed body 23, the wind load on the protection shed body 23 will be transmitted to the third slider 25 through the second mounting frame 22 and the first mounting frame 21. At this time, the third slider 25 will slide along the inside of the third slide rail 24, and at the same time drive the first spring 27 to perform telescopic deformation. The wind load is reversely offset by the elastic force of the first spring 27, and the force on the protection shed body 23 is reduced, thereby improving the stability of the protection mechanism 2 during use;

[0033] When it snows outside, the snow accumulates on the surface of the protective shed 23, and the snow load on the protective shed 23 will gradually increase. At this time, the connecting shell 28 drives the limit block 210 to slide downward along the connecting rod 29 and the limit groove 211 respectively. When the scale groove 212 is blocked by the connecting shell 28, the snow load on the surface of the protective shed 23 is too large. At this time, the electric heating tube 218 and the ventilator 217 are turned on, and the heat generated by the electric heating tube 218 is blown to the lower part of the protective shed 23 through the ventilator 217. By heating the lower part of the protective shed 23, the snow on its surface is quickly melted, thereby reducing the snow load on the protective shed 23, avoiding the collapse of the protective shed 23, and improving the safety of the protective mechanism 2.

[0034] The method of using and the working principle of the present device are as follows: the embedded base 11 is embedded in the positioning position of the mine wellhead, and then the support rod 15 and the protective mechanism 2 on its upper part are hoisted as a whole by a crane, and the support rod 15 is plugged into the mounting base 14. When the protective mechanism 2 is hoisted, the first adjusting screw rod 19 is rotated to drive the first sliding block 18 to slide along the inside of the first slide rail 12, so as to adjust the lateral position of the mounting base 14, and the second adjusting screw rod 111 is rotated to drive the second sliding block 110 to slide along the second slide rail 13, so as to adjust the longitudinal position of the mounting base 14. By adjusting the lateral and longitudinal positions of the mounting base 14, it is avoided that the support rod 15 cannot be plugged into the mounting base 14 due to the embedded deviation of the embedded base 11, so as to improve the convenience of plug-in installation of the support rod 15, and further improve the installation speed of the protective mechanism 2, and plug it into the mounting base 14 and the support rod 15 through the fixing bolt 16, and then threadedly connected with the fixing bolt 16 through the fixing nut 17;

[0035] When the protection mechanism 2 is in use, the protection shed body 23 is used to block external falling objects to prevent the falling objects from hitting people, and at the same time, the rain and snow are blocked. When strong winds blow toward the two sides of the protection shed body 23, the wind load on the protection shed body 23 will be transmitted to the third slider 25 through the second mounting frame 22 and the first mounting frame 21. At this time, the third slider 25 will slide along the inside of the third slide rail 24, and at the same time drive the first spring 27 to perform telescopic deformation, and the wind load is reversely offset by the elastic force of the first spring 27;

[0036] When it snows outside, after the snow accumulates on the surface of the protective shed body 23, the snow load on the protective shed body 23 will gradually increase. At this time, the connecting shell 28 drives the limit block 210 to slide downward along the connecting rod 29 and the limit groove 211 respectively. When the scale groove 212 is blocked by the connecting shell 28, the snow load on the surface of the protective shed body 23 is too large. At this time, the electric heating pipe 218 and the ventilator 217 are turned on, and the heat generated by the electric heating pipe 218 is blown to the lower part of the protective shed body 23 through the ventilator 217. By heating the lower part of the protective shed body 23, the snow on its surface melts quickly, thereby reducing the snow load on the protective shed body 23.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
