Description

Technical Field

[0001] The invention relates to the technical field of pipeline stacking, in particular to a special device for stacking pipelines in underground coal mines. Background Art

[0002] If underground pipelines are placed randomly, they may occupy escape routes or affect the smooth flow of evacuation routes. Once an emergency occurs (such as fire, gas explosion, etc.), the evacuation of underground personnel will be seriously affected, increasing the risk of casualties. At the same time, randomly placed pipelines will increase the probability of workers colliding with pipelines during operation, which can easily lead to work-related accidents, especially in the narrow underground environment where workers have limited space for activities. The random placement of pipelines is more likely to cause accidents.

[0003] The patent with announcement number CN219057187U discloses a special device for stacking pipelines in coal mines, which relates to the field of standardized management of coal mines. The device includes two vertically symmetrically arranged columns, the inner sides of the two columns are provided with symmetrically arranged fixing plates, and a fixing frame with an arc-shaped fixing groove is inserted into the fixing plates on both sides in turn, and the arc-shaped fixing grooves of the fixing frame opposite to each other are used to fix the pipelines. The utility model solves the problem of poor practicality, long time and poor safety of stacking pipelines. At the same time, the utility model is easy and safe to produce and install, simple to use and operate, suitable for wide promotion and application, and suitable for batch manufacturing. However, the structure in the patent can only be used for placing pipelines, not for transportation, and has a small scope of applicability. Therefore, it is very necessary to design a special device for stacking pipelines in coal mines. Summary of the invention

[0004] The purpose of the present invention is to provide a special device for stacking pipelines in coal mines to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a special device for stacking pipelines in coal mines, comprising a rack, wherein both front and rear ends of the rack are provided with pipe fixing structures, both ends of the pipe fixing structures are provided with buckle structures, a stacking positioning structure is provided above the buckle structure, and a locking structure is provided inside the stacking positioning structure;

Through the structural coordination of the plug-in slot and the positioning plug block, the positioning slot and the left pipe rack are quickly positioned by plugging, and the positioning slot and the deadweight of the left pipe rack pipeline are used to press the fixed strip, so that the fixed strip is always in contact with the rack rod, achieving rapid fixation and installation. No screws are required, which simplifies the installation steps and improves installation efficiency.

[0009] According to the above technical solution, the buckling structure includes a flip handle, which is provided at two locations. A pressure handle is fixedly connected to the side of the flip handle away from the frame rod, and a positioning screw seat is fixedly connected to the top of the pressure handle. A nut groove is provided on the top surface of the positioning screw seat, and a stud groove is provided below the nut groove. The top end of the flip handle is hingedly connected to a buckle, and a hook is provided at the bottom end of the buckle.

[0010] The two hooks are respectively fixed to the bottom surfaces of the two ends of the fixed strips to prevent the fixed strips connected to the strips from being loosened when encountering bumps during transportation. To prevent the strips connected to the strips from being separated from the fixed strips during transportation, the pressure handle is flipped to drive the pressure handle to flip around the connection point of the strips, and the buckle connected to the pressure handle is hooked on the hook. At this time, the pressure handle is pushed to make the pressure handle flip upward around the connection point of the strips to prevent the strips from being separated from the strips, so that the positioning screw seat on the top surface of the pressure handle is aligned with the stud slot on the top surface of the strip. The screw can also be put into the stud slot so that the nut of the screw presses the nut slot, further making the fixed strip fit tightly with the strip to prevent the fixed strip from being separated from the strip, and the buckle is buckled to the hook to achieve quick fixation, which is convenient for disassembly and installation, and convenient for pipeline placement and installation.

[0011] According to the above technical solution, the stacking positioning structure includes a bottom hook block, and the bottom hook blocks are provided with two pieces, each of the bottom hook blocks is located on the side of the hook buckle, and a mounting seat is provided on the side of the flip handle.

[0014] According to the above technical scheme, the displacement groove is opened inside the retractable rod, the shift block is slidably connected with the retractable block, and the locking groove and the vertical movement connecting rod constitute a locking structure. Before transportation, the fixed long strip of the upper layer needs to be placed on the flip arc rod of the bottom layer, so that the arc-shaped groove on the bottom surface of the fixed long strip fits with the top surface of the flip arc rod. At the same time, by pulling the bottom right pipe rack or the left pipe rack connected to the hanging rod rack, the hanging rod rack is pushed upward, so that the retractable rod connected to the retractable block passes through the hook column to approach the bottom hook block on the bottom surface of the upper fixed long strip. At this time, the shift block on the side of the retractable block is manually shifted to allow the shift block to drive the connected connecting rod sheet to move, and drive the connected cross connecting rod to move away from the locking groove through the connecting rod sheet. At this time, the vertical movement connecting rod connected to the cross connecting rod stretches the spring sheet to make the vertical movement connecting rod disengage from the locking groove. At this time, the hook column is pulled again to make the hook column The connected retraction rod stretches the reset spring extending from the retraction block, and the hook column is placed in the above-mentioned bottom hook block. Wait until the reset spring pulls the retraction rod to retract into the retraction block, and then release the shift block.
