[0002] Since many minerals are buried inside the mountain, it is necessary to dig mine tunnels when mining these minerals. In order to avoid the collapse of mine tunnels, various protection measures are required for mine tunnels. Mining anchors are a type of support rod widely used in coal mines, iron mines and other mining industries. Their function is to support and reinforce the roof and side walls of mining tunnels to ensure the safety and smoothness of mining work. Commonly used mining anchors are prestressed anchors and non-prestressed anchors.

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0019] An embodiment of the present invention: A device for realizing anchor rod shearing by remote control comprises a walking base 1, a mounting frame 2 is arranged on the top of the walking base 1, a working mechanism 3 is arranged at the front end of the mounting frame 2, a power supply 4 is arranged in the middle, and a control cabinet 5 is arranged at the rear end. The working mechanism 3 includes a vertical mounting frame 6, on which a vertical guide rod 7 is arranged, on which a movable seat 8 is slidably sleeved, and the movable seat 8 is connected to a push rod of a height-adjusting hydraulic cylinder 9, which is arranged on the mounting frame 2, and a rotary hydraulic motor 10 is connected to the top of the movable seat 8, and an output end of the rotary hydraulic motor 10 is connected to a support seat 11, and the support seat 11 is hingedly connected to the tail end of an execution frame 12, and a lateral mounting plate 13 is arranged on the side of the support seat 11, and an angle-adjusting hydraulic cylinder 14 is hingedly mounted on the lateral mounting plate 13, and the output end of the angle-adjusting hydraulic cylinder 14 is hingedly connected to the middle bottom position of the execution frame 12, and a length-adjusting hydraulic cylinder 15 is installed in the execution frame 12, and the output end of the length-adjusting hydraulic cylinder 15 is connected to a hydraulic shear 17 via a connecting piece 16.

[0020] During the use of this device, the power supply 4 provides the required power to each electrical device, and the controller inside the control cabinet 5 controls the actions of each actuator, mainly the action of the working mechanism 3. During the control process of the working mechanism 3, the push rod of the height adjustment cylinder 9 is extended to drive the movable seat 8 to move upward along the vertical guide rod 7, thereby changing the height of the entire working mechanism 3. The support seat 11 can be driven to rotate 360° horizontally by rotating the hydraulic motor 10. The actuator frame 12 can be driven to rotate to different angles by the angle adjustment hydraulic cylinder 14. The extension length of the working mechanism 3 can be adjusted by the length adjustment hydraulic cylinder 15. Through the joint control of the above-mentioned various mechanisms, the anchor rod at any position is inserted into the hydraulic shear 17, and the hydraulic shear 17 can be driven to automatically shear the anchor rod. This enables the device to automatically shear the anchor rod at any position.

[0021] The control cabinet 5 is equipped with driving mechanisms of various hydraulic mechanisms. The driving mechanism of the walking base 1 is two motors and their connected reduction mechanisms. Each motor and its connected reduction mechanism drives the walking wheels on one side of the walking base 1 to travel. The driving mechanism of each hydraulic mechanism is composed of an oil tank, a radiator, a hydraulic power device, a proportional valve, etc., through which the required hydraulic power is provided for the height adjustment hydraulic cylinder 9, the rotary hydraulic motor 10, the angle adjustment hydraulic cylinder 14 and the length adjustment hydraulic cylinder 15. A controller is also arranged inside the control cabinet 5. The controller is used to control the actions of various actuators on the device for automatically realizing anchor shearing. At the same time, the controller can also realize wireless connection with the remote controller, so as to control the actions of the device through remote control.

[0022] The control cabinet 5 is provided with a fire extinguisher 18 and a buzzer 19 on the surface and a warning light 20 on the top. When a fire occurs, the fire extinguisher 18 can be used to put out the fire. When an emergency occurs, the buzzer 19 emits an alarm sound and the warning light 20 flashes continuously.

[0023] The power source 4 is a battery, which has mature technology and is relatively convenient to charge.

[0024] A hydraulic oil supply device 21 is provided on the mounting frame 2 on the side of the height adjustment hydraulic cylinder 9. The hydraulic oil supply device 21 is connected to the hydraulic shear 17 via a pipeline. Because the hydraulic shear 17 needs to provide a large amount of hydraulic pressure, a separate hydraulic oil supply device 21 is provided to provide it with the required hydraulic pressure.

[0025] The vertical mounting frame 6 and the rear end of the mounting frame 2 are both provided with lifting ears 22, which facilitate the lifting of the entire device for automatically shearing the anchor rod.

[0026] The execution frame 12 is composed of front, rear, left and right side plates which are fixedly connected to each other. A length-adjusting hydraulic cylinder 15 is arranged between the front side plate and the left and right side plates along the length thereof. The head end of the push rod of the length-adjusting hydraulic cylinder 15 is connected to the connecting piece 16. A reinforcing plate 23 is slidably engaged inside each of the left and right side plates. The reinforcing plate 23 is arranged along the length direction of the execution frame 12. The head end of the reinforcing plate 23 passes through the front side plate and is fixedly connected to the side of the connecting piece 16. Because the connecting piece 16 and the hydraulic shear 17 themselves have a certain mass, in order to prevent the push rod of the length-adjusting hydraulic cylinder 15 from bending under the gravity of the connecting piece 16 and the hydraulic shear 17 themselves after being pushed out, a reinforcing plate 23 is provided to improve the bending resistance of the push rod of the length-adjusting hydraulic cylinder 15.

[0027] The reinforcing plate 23 is an L-shaped structure, which is not easily deformed, ensuring that the push rod of the length-adjusting hydraulic cylinder 15 will not bend even if it is extended to a long length.

[0028] A bottom support plate 24 is horizontally arranged between the middle side walls of the vertical mounting frame 6, and two vertical guide rods 7 are installed between the bottom support plate 24 and the top plate of the vertical mounting frame 6. A movable seat 8 is slidably sleeved on the vertical guide rod 7. When the height-adjusting hydraulic cylinder 9 moves downward, the movable seat 8 is supported on the bottom support plate 24, and the entire movable seat 8 and its upper structure are supported by the bottom support plate 24. The bottom support plate 24 transmits the pressure it bears to the vertical mounting frame 6, and the vertical mounting frame 6 transmits it to the mounting frame 2. The mounting frame 2 mainly bears the pressure. At this time, the push rod of the height-adjusting hydraulic cylinder 9 is not under pressure, thereby improving the service life of the height-adjusting hydraulic cylinder 9.

[0029] The walking base 1 is a crawler-type walking base, which is more suitable for the uneven ground environment of mine tunnels.
