Description

Technical Field

[0001] The utility model relates to the technical field of mine protection, in particular to safety protection equipment for open-pit mines. Background Art

[0002] The potential safety hazard of open-pit mines is that rocks are prone to fall, and the existing technical solution is to use baffles to surround the places that are prone to fall. Since falling rocks directly hit the baffles, they will have a large impact force, thereby damaging the equipment and shortening the service life of the equipment. In addition, due to the different terrain or location of the mine, the height requirements for protection are different. The traditional fixed baffle cannot adjust the height and is relatively limited in use. Therefore, in response to the above problems, a safety protection device for open-pit mines is proposed. Utility Model Content

[0012] 2. The utility model uses the setting of a motor, a threaded rod, a moving block and a lifting plate. The motor is started to drive the threaded rod to rotate, and the threaded rod causes the moving block to move upward. At the same time, the moving block on the other side slides on the surface of the guide rod, so that the moving blocks moving upward on both sides drive the lifting plate to move upward, and then the lifting plate comes out of the bottom plate and extends the protection height. Through the setting of the motor, the threaded rod, the moving block and the lifting plate, it can be adjusted according to different terrains and protection height requirements. The operation is simple, convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS

Mechanism 11, first move the equipment to the mine through the pulley 2, and fix the equipment by rotating the fixed cone 4 inside the threaded sleeve 3. After fixation, the buffer mechanism 11 buffers the impact of falling rocks on the bottom plate 5, thereby protecting the equipment and improving the service life of the equipment. The bottom plate 5 can block most of the falling rocks to prevent the falling rocks from crushing the vehicle. When the infrared sensor 9 senses that someone is approaching the bottom plate 5, the central control console 6 controls the alarm 8 to sound an alarm to remind people to stay away from the dangerous area, and the display screen 7 is used to set prompt text to remind passing vehicles and passers-by, and the reflective strip 12 is set so that people can see the protective equipment when driving at night, thereby alerting people to protect safety.

[0022] Wherein, reflective strips 12 are fixedly connected to both sides of the front side of the bottom plate 5 , and the reflective strips 12 are located on the sides of the bottom plate 5 .

[0023] Among them, a motor 14 is fixedly connected to one side of the top of the base plate 5, and a threaded rod 15 is rotatably connected to the output end of the motor 14. The bottom end of the threaded rod 15 passes through the top wall of the base plate 5 and is rotatably connected to the inside of the base plate 5. A guide rod 16 is fixedly connected to the other side of the inside of the base plate 5. When protecting different areas, the height of the protection range often needs to be different, so the motor 14 is started to drive the threaded rod 15 to rotate, and the threaded rod 15 makes the moving block 17 move upward. At the same time, the moving block 17 on the other side slides on the surface of the guide rod 16, so that the moving blocks 17 moving upward on both sides drive the lifting plate 13 to move upward, and then the lifting plate 13 comes out of the base plate 5 to increase the protection height.

[0024] Among them, moving blocks 17 are fixedly connected to both sides of the lifting plate 13, and the moving blocks 17 are located inside the bottom plate 5. One of the moving blocks 17 is threadedly connected to the surface of the threaded rod 15, and the other moving block 17 is slidably connected to the surface of the guide rod 16.

[0025] Among them, the buffer mechanism 11 includes a baffle 111, one side of the baffle 111 is fixedly connected to a waterproof pad 112, one side of the waterproof pad 112 is fixedly connected to an airbag 113, one side of the airbag 113 is fixedly connected to an inflation port 114, the surface of the airbag 113 is fixedly connected to an air release port 115, and the air release port 115 is located on the bottom side of the inflation port 114.

[0026] The buffer mechanism 11 further comprises a fixing rod 116, which is fixedly connected to the back of the bottom plate 5. The number of fixing rods 116 is set to be multiple, and a slider 117 is slidably connected to the surface of the fixing rod 116. The number of sliders 117 is set to two, and a connecting rod 118 is rotatably connected between the surfaces of the two sliders 117 and the baffle 111. A buffer spring 119 is sleeved on the outside of the fixing rod 116, and the buffer spring 119 is located on one side of the slider 117. When buffering is performed by the buffer mechanism 11, the airbag 113 is first inflated through the air inlet 114, and then the falling rock falls and hits the falling rock. Towards one side of the baffle 111, after the first buffering by the airbag 113, it can play a protective role on the baffle 111 and prevent the falling rocks from directly hitting the baffle 111 and damaging the baffle 111. Then the falling rocks push the baffle 111 to one side of the bottom plate 5, and the baffle 111 squeezes the connecting rod 118 to make the slider 117 slide on the fixed rod 116 and squeeze the buffer spring 119, so that the longitudinal force of the falling rocks on the baffle 111 is laterally decomposed by the buffer spring 119, thereby playing a role in buffering the floor, protecting the floor and increasing the service life of the equipment.

[0027] Working principle: when in use, the device is first moved to the mine where it is to be installed through the pulley 2, and the device is fixed by rotating the fixing cone 4 inside the threaded sleeve 3. After fixing, the impact of falling rocks on the bottom plate 5 is buffered by the buffer mechanism 11, thereby protecting the device and improving the service life of the device. The bottom plate 5 can block most of the falling rocks to prevent the falling rocks from crushing the vehicle. When the infrared sensor 9 senses that someone is approaching the bottom plate 5, the central control console 6 controls the alarm 8 to sound an alarm or flash a warning light to remind people to stay away from the dangerous area, and a prompt text is set on the display screen 7 to remind passing vehicles and passers-by, and the reflective strip 12 is set so that people can see the protective equipment when driving at night, thereby alerting people to protect safety;

[0028] When protecting different areas, the height of the protection range is often different. The motor 14 is started to drive the threaded rod 15 to rotate, and the threaded rod 15 makes the moving block 17 move upward. At the same time, the moving block 17 on the other side slides on the surface of the guide rod 16, so that the moving blocks 17 moving upward on both sides drive the lifting plate 13 to move upward, and then the lifting plate 13 comes out from the bottom plate 5 to increase the protection height. Through the arrangement of the motor 14, the threaded rod 15, the moving block 17 and the lifting plate 13, it can be adjusted according to different terrains and the height of protection. The operation is simple, convenient and fast.

[0029] When buffering is performed through the buffer mechanism 11, the airbag 113 is first inflated through the air inlet 114, and then the falling rock hits one side of the baffle 111 after falling. After the first buffering by the airbag 113, it can protect the baffle 111 and prevent the falling rock from directly hitting the baffle 111 and damaging the baffle 111. Then, the falling rock pushes the baffle 111 to be squeezed toward one side of the bottom plate 5, and the baffle 111 squeezes the connecting rod 118 to make the slider 117 slide on the fixed rod 116, and squeezes the buffer spring 119, so that the longitudinal force of the falling rock on the baffle 111 is laterally decomposed by the buffer spring 119, thereby playing a role in buffering the bottom plate, protecting the bottom plate, and increasing the service life of the equipment.
