Description

Technical Field

[0001] The utility model relates to the technical field of anti-collapse protection equipment, in particular to an anti-collapse protection device. Background Art

[0002] Safety engineering is an engineering field that focuses on various accidents that occur in human production and daily life activities. It uses the relevant knowledge and achievements of natural sciences, technical sciences, and management sciences to identify and predict unsafe factors in production and daily life activities, and to take effective control measures to prevent accidents or reduce accident losses. When conducting underground operations such as coal mining, corresponding anti-collapse protection devices are required to prevent the collapse of underground structures.

[0003] After searching, the utility model patent with Chinese patent publication (announcement) number CN219774160U discloses an anti-collapse protection device for safety engineering, which is roughly described as comprising a base plate and a support plate. A support frame is provided on one side of the base plate, a support column is slidably provided on the top of the support frame, a base is horizontally provided on the top of the two support columns, and a pressure plate is slidably provided on one side of the base. When in use, the support plate supports and protects the underground structure through the support plate. The support plate contacts and supports the top of the mine cave. The support plate deforms and fits the top of the mine cave. The contact area between the support plate and the mine cave is larger, and the support and protection effect is better. However, the above device still has certain shortcomings. For example, the above device is only convenient for supporting and protecting the top of the mine cave, but not convenient for supporting and protecting the two sides of the mine cave. There are certain deficiencies in protection and practicality. In addition, a rotating rod, connecting pipe, etc. are provided in the middle of the above device. When workers or mechanical equipment pass through the device, they are relatively obstructive and may trip workers, thereby causing danger. To this end, we propose an anti-collapse protection device.

[0032] The limiting mechanism is provided on the turntable 13 and the support frame 7. The limiting mechanism includes a plurality of limiting grooves 14 and two hand screws 15. The plurality of limiting grooves 14 are provided on the support frame 7. The two hand screws 15 are threadedly connected to the turntable 13. One end of the hand screw 15 is located in one of the limiting grooves 14. The hand screw 15 is used to facilitate people to rotate and rotate into the limiting groove 14, which can limit the turntable 13 and the threaded shaft 8.

[0033] The moving mechanism is arranged on the base 1. The moving mechanism includes multiple openings, all of which are opened on the base 1. A slide 16 is rotatably connected in the opening, and a block 17 is slidably connected in the slide 16. A slot is opened in the opening, and one end of the block 17 is located in the slot. A plurality of springs 18 are arranged between the block 17 and the slide 16. A control block 19 is fixedly connected to the block 17, and the control block 19 passes through the slide 16 through the control port. Two cleaning ports are opened on the slide 16, and a moving wheel 20 is fixedly connected to the slide 16. The cleaning port is used to facilitate people to clean the soil in the slide, etc., and the slide 16 is used to rotate and accommodate the moving wheel 20.

[0037] In summary, the working principle and working process of the anti-collapse protection device are as follows: when in use, the anti-collapse protection device is first placed at the desired location, and then people can slide the control block 19, and the control block 19 drives the card block 17 to move. At this time, the card block 17 squeezes the spring 18, and the card block 17 moves out of the card slot. Then, due to gravity, the base 1 will fall, and the slide 16 will rotate, and the slide 16 drives the moving wheel 20 to retract. In this way, the base 1 falls to the ground, and the moving wheel 20 no longer supports the base 1, and the entire device cannot move. Then people can first turn down the multiple fixing bolts 4, and then move the support column 3 to make the anti-collapse protection device The guard plate 6 is pressed against the top wall of the mine, and then the staff installs the fixing bolts 4, passes the fixing bolts 4 through the limit holes and fixes the support column 3, thus completing the top support. Then the staff turns the hand-tightening screw 15 and turns the turntable 13 to make the turntable 13 drive the threaded shaft 8 to rotate. Because there are multiple telescopic rods 12 fixedly connected between the protective frame 10 and the support frame 7, the rotation of the threaded shaft 8 will force the threaded cylinder 9 to move, and the telescopic rod 12 will expand and contract accordingly, so that the protective frame 10 and the protective net 11 will be pressed against the side wall of the mine, and then the staff turns the hand-tightening screw 15 into the limit groove 14 for limiting.

[0038] The above embodiments merely represent specific implementation methods of the present invention. Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
