Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic props, in particular to an underground hydraulic prop capable of intelligently sensing pressure changes. Background Art

[0002] In the coal mining industry, hydraulic props are one of the important equipment to ensure the safety and stability of coal mining faces. With the increase in coal production year by year, the performance and safety requirements of hydraulic props are getting higher and higher.

[0003] Especially in underground mining environments, due to the complex and changeable geological conditions, hydraulic supports need to withstand various uncertain pressure changes, and when a group of hydraulic supports lose support, there is a lack of necessary alarm means, and other hydraulic supports will not adjust the pressure according to the pressure changes. As time goes by, the area that loses support will greatly increase the risk of roof collapse; and in actual environments, the hydraulic supports will directly interact with dust and impurities in the outside air, resulting in a reduction in the service life of the hydraulic supports, thereby increasing the cost of use.

[0004] Therefore, it is of great practical significance to develop an underground hydraulic prop that can intelligently sense and adapt to pressure changes. Utility Model Content

[0005] In order to solve the technical problems that traditional hydraulic props cannot transmit information in time according to pressure conditions during support and cannot perform adaptive pressure support changes, which greatly reduces the safety factor, the utility model provides an underground hydraulic prop with intelligent sensing of pressure changes.

[0011] The disassembly and assembly mechanism is arranged in the dustproof shell to be used for quick disassembly and assembly of the sensing device.

[0012] Through the above technical scheme, the hydraulic rod installed in the dustproof shell can play a good dustproof role, and under the action of the installation mechanism, the hydraulic rod can be quickly installed in the dustproof shell and fixed; then the equipment can also quickly install the sensing device under the action of the disassembly and assembly mechanism, and perform real-time pressure monitoring of the hydraulic rod and transmit information and adjust the pressure according to the actual pressure conditions, thereby further improving production safety.

[0013] As a further improvement of the above scheme, the mounting mechanism includes baffles fixed by bolts at the upper and lower ends of the dustproof shell, and movable grooves are opened in the baffles corresponding to the two ends of the hydraulic rod, and the outer wall of the plunger at the bottom end of the hydraulic rod is fixedly connected with a mounting sleeve block, and the mounting sleeve block is fixedly connected to the baffle at the bottom end of the dustproof shell.

[0014] Through the above technical solution, the hydraulic rod is installed and fixed by using two baffles and a mounting sleeve block.

[0015] As a further improvement of the above scheme, the disassembly and assembly mechanism includes a positioning plate, which is fixedly installed on the inner wall of the dustproof shell and is arranged corresponding to the piston rod of the hydraulic rod. Vertical plates are staggered and fixedly connected on both sides of the positioning plate, and the sides where the two groups of vertical plates are close to each other are fixedly connected with top plates.

[0016] Through the above technical solution, the staggered vertical plates are used to facilitate the adjustment of the sliding installation of the sensing device, and to achieve quick blocking and positioning, and then lock it.

[0017] As a further improvement of the above scheme, the outer wall of the hydraulic rod piston rod is slidably connected to a sensing device, and a pressure sensor and an information processing and transmission module are arranged in the sensing device. A data display screen is arranged on one side of the sensing device for real-time monitoring of pressure changes and information transmission.

[0018] As a further improvement of the above scheme, movable sleeves are symmetrically fixedly connected on both sides of the sensing device by bolts, and the outer sides of the two groups of movable sleeves are telescopically connected with rotating wheels, and an elastic material is provided at the middle connection between the movable sleeves and the rotating wheel, and the elastic material is a spring, and a sleeve is provided at the center of the upper and lower ends of the rotating wheel.

[0019] As a further improvement of the above scheme, the top ends of the two groups of top plates are vertically slidably connected with plug rods, and the top ends of the two groups of plug rods are fixedly connected with circular plates, springs are elastically connected between the two groups of top plates and the two groups of circular plates, and the bottom ends of the plug rods are provided with rounded corners.

[0020] Through the above technical solution, the spring elasticity is utilized to push the rotating wheel so that it can slide horizontally in the movable sleeve block, so that the sensing device can utilize the rotating wheel to slide against the upper surface of the positioning plate during the sliding installation, and as the sensing device rotates, the rotating wheel can be quickly positioned at the vertical plate, and can drive the insertion rod to slide vertically upward, and then the elastic rebound of the spring is utilized to push the insertion rod into the inner wall of the sleeve to complete the locking of the sensing device, and unlocking only requires lifting the circular plate upward to release the lock, and rotating the sensing device in the opposite direction to release the positioning.
