Description

Technical Field

[0001] This utility model relates to the field of coal mine roadway support, specifically to a resin cartridge connection device. Background Technology

[0002] Underground coal mine operations rely heavily on roadway support. However, underground coal mine roadways are generally over 2.2 meters high, with some exceeding 4 meters. When pushing three resin cartridges into pre-drilled holes in the roof, one worker needs to stand on a ladder, push one cartridge into the hole, and then use one hand to block the hole to prevent the cartridge from slipping out. Another worker then hands the cartridge back to the worker on the ladder, and so on. Even though existing resin cartridge spraying anti-fall caps (publication number CN117231271A) can prevent resin cartridges from slipping out of the holes, workers still need to climb up and down the ladder multiple times to insert all three cartridges into the pre-drilled holes. Due to the complex underground working environment—dark, damp, and uneven ground—safety hazards are increased to some extent. Adding more workers to stand below the ladder to deliver the cartridges would increase labor costs and reduce work efficiency. Utility Model Content

[0003] The main purpose of this utility model is to overcome the above-mentioned shortcomings and propose a resin cartridge connecting device that allows only one person to smoothly insert three resin cartridges into the reserved drilled holes and prevent them from slipping out.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a resin cartridge connecting device, comprising a cylinder, claws, and a collar, characterized in that: the cylinder is a hollow cylinder open at both ends; a limiting ring is coaxially arranged in the middle of the cylinder, the limiting ring having a hollow circular cross-section, dividing the cylinder into an upper chamber and a lower chamber; barbs are arranged in the same direction in the middle of the outer side of the cylinder; claws are symmetrically arranged on the two circular end faces of the cylinder; one end of the claw is fixedly connected to the circular end face of the cylinder; the inner side of the other end is provided with a claw tip, and the outer side is provided with a protrusion and a limiting pin; the claw tip is located on the inner side at the middle position between the limiting pin and the protrusion, and the claw tip faces the center of the cylinder; a collar is arranged on the outer side of the cylinder, the inner diameter of the collar being larger than the outer diameter of the cylinder, the inner diameter of the collar being smaller than the maximum distance between the two protrusions in the natural state, and the inner diameter of the collar being smaller than the maximum distance between the two limiting pins in the natural state.

[0005] Preferably, each circular end face has no fewer than two claws.

[0006] Preferably, the number of barbs is no less than 2.

[0007] Preferably, the claws, collars, and barbs are made of elastic materials, which can deform to a certain extent when subjected to force.

[0008] The beneficial effects of this utility model are: when installing resin pills, workers do not need to climb up and down ladders multiple times, nor do they need the assistance of other personnel, and can smoothly push the resin pills into the reserved drill holes and fix them, which is conducive to the safety of workers, convenient and quick installation, saving time, improving work efficiency, and the resin pills are not easy to fall and break during installation, avoiding losses.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Please see Figures 1-6A resin cartridge connecting device includes a cylindrical body 101, claws 201, and a collar 301. The cylindrical body 101 is a hollow cylinder open at both ends. A limiting ring 102 is coaxially arranged in the middle of the interior of the cylindrical body 101. The limiting ring 102 has a hollow circular cross-section and divides the cylindrical body 101 into an upper chamber 103 and a lower chamber 104. Barbs 401 are arranged in the same direction in the middle of the exterior of the cylindrical body 101. Claws 201 are symmetrically arranged on the two circular end faces of the cylindrical body 101, with one end of each claw 201 engaging with the circular end face of the cylindrical body 101. The end face is fixedly connected, and the inner side of the other end is provided with a claw tip 203, and the outer side is provided with a protrusion 204 and a limiting pin 202. The claw tip 203 is located on the inner side at the middle position of the limiting pin 202 and the protrusion 204. The claw tip 203 of the claw 201 faces the center position of the cylinder 101. A collar 301 is provided on the outside of the cylinder 101. The inner diameter of the collar 301 is larger than the outer diameter of the cylinder 101. The inner diameter of the collar 301 is smaller than the maximum distance between the two protrusions 204 in the natural state. The inner diameter of the collar 301 is smaller than the maximum distance between the two limiting pins 202 in the natural state.

[0018] Preferably, each circular end face has no fewer than two claws.

[0019] Preferably, the number of barbs 401 is no less than 2.

[0020] Preferably, the claw 201, collar 301, and barb 401 are made of elastic materials, which can undergo a certain degree of deformation under stress.

[0021] In use, insert the resin cartridge 501 into the upper chamber 103 and move the collar 301 upwards.

[0022] Multiple claws 201 retract inward under the force of the collar 301, and the claw tips 203 bite the resin cartridge 501, thereby fixing the resin cartridge 501 to the upper chamber 103. In the same way, another resin cartridge 501 is fixed to the lower chamber 104, thus connecting the two resin cartridges.

[0023] Please see Figures 1-2 External threads can be provided on the outside of the jaws 201 and internal threads on the inside of the collar 301 to replace the locking function of the limit pin 202 and the protrusion 204. When the resin cartridge 501 is inserted into the upper chamber 103 and the collar 301 is rotated, the multiple jaws 201 retract inward under the force of the collar 301, and the jaw tips 203 bite the resin cartridge 501, thus fixing the resin cartridge 501 to the upper chamber 103. In the same way, another resin cartridge 501 is fixed to the lower chamber 104, thus connecting the two resin cartridges.
