Description

Technical Field

[0001] This utility model relates to an anchor bolt traction device for fully mechanized mining faces, belonging to the technical field of coal mine roadway technology. Background Technology

[0002] During coal transportation in fully mechanized mining faces and in return airways, anchor bolts on the coal face may become embedded in the coal seam or collapse with the coal blocks, becoming trapped underneath. Manually removing these anchor bolts is time-consuming, labor-intensive, and poses a safety risk to workers. Furthermore, manual removal cannot guarantee the complete removal of all anchor bolts; any missed bolts transported with the coal blocks to the conveyor belt can easily tear the belt, causing incalculable losses. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an automatic traction and recovery device for anchor bolts in fully mechanized mining faces, which is easy to operate and can quickly and automatically remove all anchor bolts, reducing the labor intensity of workers and ensuring their personal safety.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: an automatic anchor bolt traction device for fully mechanized mining faces, including a base, a drum mounting seat fixed on the base, two ends of a wire rope traction drum mounted on the drum mounting seat, a traction wire rope wound on the wire rope traction drum, a reversing unit provided above the wire rope traction drum, the lead-out end of the traction wire rope being led out vertically and then automatically reversed to a horizontal state by the reversing unit; a slide is provided outside the reversing unit, and the lead-out end of the traction wire rope is fixedly connected to the slide; multiple tensioning wheels are arranged vertically at intervals inside the slide, tensioning wire ropes are wound on the tensioning wheels, and locking connectors are respectively provided at the lead-out ends of the tensioning wire ropes, the locking connectors being fixedly connected to the corresponding anchor bolts; driving the wire rope traction drum to rotate causes the traction wire rope to be wound onto the wire rope traction drum, pulling the slide to move, causing the tensioning wire rope and locking connectors to pull out the anchor bolts.

[0005] The reversing unit includes two horizontally spaced casters, one of which is located directly above the traction steel wire rope; the caster is fixed to the coal mining equipment by a fixing frame.

[0006] A sliding groove is provided on the top of the slide frame, and a slider is provided on the coal mining equipment. The sliding groove and the slider are engaged.

[0007] The carriage is symmetrically provided with connecting plates on both sides, and connecting holes are opened on the connecting plates respectively. Connecting rods are inserted into the connecting holes, and the lead-out end of the traction steel wire rope is connected to the connecting rod.

[0008] The base is also equipped with a power source and a hydraulic motor. The power source drives the hydraulic motor to rotate, and the hydraulic motor drives the wire rope traction drum to rotate, thereby winding up or releasing the traction wire rope.

[0009] The base is equipped with an operating valve, which is signal-connected to the power source tension automatic control mechanism. The operating valve opens the power source tension automatic control mechanism. The power source tension automatic control mechanism includes an anchor bolt preload sensor and a power source switch controller. The anchor bolt preload sensor detects the anchor bolt preload and feeds it back to the power source switch controller. The power source switch controller is signal-connected to the power source and automatically controls the start and stop of the power source.

[0010] The power source can be an emulsion-powered motor, a pneumatic motor, or a power module, or any two power sources can be selected and used in combination. The equipment can be operated remotely.

[0011] Compared with existing technologies, the advantages of this utility model are as follows: An automatic anchor bolt traction device for fully mechanized mining faces can be installed and used in conjunction with any anchor removal unit or other fully mechanized mining face equipment. This device can use one power source to control one set of wire rope traction drums and one set of power source tension automatic control mechanisms for anchor bolt retrieval. Alternatively, one power source can be used on the same equipment to control two or more sets of wire rope traction drums and power source tension automatic control mechanisms for anchor bolt retrieval. Operation is convenient and safe. When retrieving anchor bolts, the locking connectors are connected and locked to the anchor bolts on each side; then workers can move away from the danger zone. By operating the valve to open the automatic control mechanism for the power source tension, when the tension detected by the anchor bolt preload sensor reaches the set value, the power source switch controller automatically shuts off the power source, and the entire equipment automatically stops working. During coal mining, when the anchor bolt preload decreases, the tension detected by the anchor bolt preload sensor also decreases simultaneously. The power source switch controller automatically opens the power source, which drives the hydraulic motor to rotate, causing the wire rope traction drum to rotate. The traction wire rope pulls the slide, causing the locking connector to pull out the anchor bolt, achieving rapid and complete anchor bolt recovery. This reduces the labor intensity of workers, ensures their personal safety, and protects the belt conveyor system from anchor bolt damage. Attached Figure Description

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 , 2 As shown, this embodiment of a fully mechanized mining face anchor bolt traction device includes a base 1, on which a drum mounting seat 3 is fixed. Both ends of the wire rope traction drum 3 are mounted on the drum mounting seat 3, and a traction wire rope 9 is wound around the wire rope traction drum 4. Two spaced-apart casters 6 are provided above the base 1, with one caster 6 positioned directly above the traction wire rope 9. The caster 6 is fixed to the anchor removal machine frame or other fully mechanized mining face equipment via a fixing frame 7. A slider is provided on the anchor removal machine frame, and a slide frame 10 is provided on the outer side of the caster. A groove is opened at the top of the slide frame 10, and the groove holds the slider. The vertically extended traction wire rope 9 is supported on the two casters 6, and the two casters automatically reverse the direction of the traction wire rope, changing it from a vertical to a horizontal state. The lead-out end of the traction wire rope 9 is fixedly connected to the slide frame 10. Four tensioning wheels 8 are provided inside the slide frame 10, and the four tensioning wheels 8 are evenly spaced vertically along the slide frame 10. Tensioning wire ropes 13 are wound around the tensioning wheel 8. Locking connectors 12 are fixedly installed at the leads of the tensioning wire ropes 13, and each locking connector 12 is locked to its corresponding anchor rod. The tensioning wheel 8 keeps the tensioning wire ropes 13 under constant tension. The base 1 is equipped with a power source 2 and a hydraulic motor. The power source 2 drives the hydraulic motor to rotate, which in turn drives the wire rope traction drum 4 to rotate, thereby winding up the traction wire rope. The wound traction wire rope 9 pulls the slide 10 along the slider, causing the tensioning wire rope 13 and locking connectors 12 to pull out the anchor rod; or the traction wire rope is released, and the slide is reset by a spring or disc spring.

[0017] Springs or disc springs are horizontally mounted on the slide, the anchor removal machine frame, or other fully mechanized mining equipment.

[0018] Connecting plates 11 are symmetrically arranged on both sides of the carriage 10. Connecting holes are opened on the connecting plates respectively, and connecting rods are inserted into the connecting holes. The lead-out end of the traction wire rope is connected to the connecting rod.

[0019] The base frame is also equipped with an operating valve 5, which is connected to the power source tension automatic control mechanism 14. The power source tension automatic control mechanism includes an anchor bolt preload sensor and a power source switch controller. The anchor bolt preload sensor detects the anchor bolt preload and feeds it back to the power source switch controller. The power source switch controller is connected to the power source signal and can automatically control the start and stop of the power source. When the tension detected by the anchor bolt preload sensor reaches the set value, the power source switch controller automatically shuts off the power source, and the entire equipment automatically stops working. During coal mining, when the anchor bolt preload decreases, the tension detected by the anchor bolt preload sensor also decreases simultaneously. The power source switch controller automatically turns on the power source, and the power source drives the hydraulic motor, causing the wire rope traction drum to rotate. The traction wire rope pulls the slide, causing the locking connector to pull out the anchor bolt, achieving rapid and complete recovery of the anchor bolt. This reduces the labor intensity of workers, ensures their personal safety, and protects the belt conveyor system from anchor bolt damage.

[0020] The power source can be an emulsion-powered motor, a pneumatic motor, or a power module, or any combination of two power sources can be selected.

[0021] This application is easy to operate. When removing the anchor, the locking connector is connected and locked to each side anchor; then workers can move away from the danger zone. Opening the operating valve automatically controls the start and stop of the power source through the automatic power source tension control mechanism, causing the hydraulic motor to drive the wire rope traction drum to rotate, pulling the wire rope to pull the slide, thus pulling out the tensioned wire rope and locking connector to remove the anchor. This allows for the rapid removal of all anchors, reducing the labor intensity of workers, ensuring their personal safety, and protecting the belt conveyor system from anchor damage.

[0022] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
