Description

Technical Field

[0001] This invention relates to an anchor bolt shearing device, and more particularly to a device for remotely controlling anchor bolt shearing. Background Technology

[0002] Since many minerals are buried inside mountains, mining requires excavating mine roadways. To prevent roadway collapse, various protective measures are necessary. Mining anchors are widely used support rods in mining industries such as coal and iron ore mines. Their function is to support and reinforce the roof and sidewalls of mining roadways, ensuring the safety and smooth operation of mining work. Commonly used mining anchors include prestressed anchors and non-prestressed anchors. Prestressed anchors are suitable for mining faces with strong support and large roadway deformation, while non-prestressed anchors are suitable for light support and temporary support.

[0003] After the installation of mining anchor bolts, a portion of their ends will protrude. This exposed portion needs to be cut off. Currently, the common method of cutting is manual operation with hydraulic shears. This method is not only inefficient, but also carries inherent safety risks for workers operating inside mine tunnels. Summary of the Invention

[0004] The purpose of this invention is to provide a device for remotely controlling anchor bolt shearing. This device can automatically shear anchor bolts, which not only improves shearing efficiency but also eliminates the need for workers to enter the mine roadway, reducing safety risks.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0020] An embodiment of the present invention: A device for remotely controlling anchor bolt shearing includes a walking base 1, an installation frame 2 is provided on the top of the walking base 1, a working mechanism 3 is provided at the front end of the installation frame 2, a power supply 4 is provided in the middle, and a control cabinet 5 is provided at the rear end. The working mechanism 3 includes a vertical mounting frame 6, on which a vertical guide rod 7 is provided. A movable seat 8 is slidably sleeved on the vertical guide rod 7. The movable seat 8 is connected to the push rod of a height-adjusting hydraulic cylinder 9. The height-adjusting hydraulic cylinder 9 is mounted on the mounting frame 2. A rotary hydraulic motor 10 is connected to the top of the movable seat 8. The output end of the rotary hydraulic motor 10 is connected to a support seat 11. The support seat 11 is hinged to the tail end of the execution frame 12. A lateral mounting plate 13 is provided on the side of the support seat 11. An angle-adjusting hydraulic cylinder 14 is hinged on the lateral mounting plate 13. The output end of the angle-adjusting hydraulic cylinder 14 is hinged to the middle bottom position of the execution frame 12. A length-adjusting hydraulic cylinder 15 is installed inside the execution frame 12. The output end of the length-adjusting hydraulic cylinder 15 is connected to a hydraulic shear 17 via a connector 16.

[0021] During operation, the device supplies power to all electrical equipment via power source 4, and controls the actions of various actuators, primarily the working mechanism 3, via the controller inside control cabinet 5. During the control of the working mechanism 3, the extension of the push rod of the height-adjusting hydraulic cylinder 9 moves the movable seat 8 upwards along the vertical guide rod 7, thus changing the height of the entire working mechanism 3. The rotation of the hydraulic motor 10 rotates the support seat 11 horizontally 360°. The angle-adjusting hydraulic cylinder 14 rotates the actuator frame 12 at different angles, and the length-adjusting hydraulic cylinder 15 adjusts the extension length of the working mechanism 3. Through the combined control of these mechanisms, the anchor bolt at any position can be engaged in the hydraulic shear 17, and the hydraulic shear 17 can automatically cut the anchor bolt. This allows the device to automatically cut anchor bolts at any position.

[0022] The control cabinet 5 houses the drive mechanisms for each hydraulic system. The drive mechanism for the traveling base 1 consists of two motors and their connected reduction gears. Each motor and its connected reduction gear drives the traveling wheels on one side of the traveling base 1. Each hydraulic system's drive mechanism comprises an oil tank, radiator, hydraulic power unit, proportional valve, etc., providing the necessary hydraulic power to the height-adjusting hydraulic cylinder 9, the rotary hydraulic motor 10, the angle-adjusting hydraulic cylinder 14, and the length-adjusting hydraulic cylinder 15. The control cabinet 5 also contains a controller, which controls the actions of each actuator on the automatic anchor bolt shearing device. This controller can also wirelessly connect to a remote control, allowing for remote control of the device's operation.

[0023] The control cabinet 5 is equipped with a fire extinguisher 18 and a buzzer 19 on its surface, and a warning light 20 on its top. In case of fire, the fire extinguisher 18 can be used to extinguish the fire. In case of emergency, the buzzer 19 will sound an alarm, and the warning light 20 will flash continuously.

[0024] The power source 4 is a rechargeable battery, which is a mature technology and relatively easy to charge.

[0025] A hydraulic oil supply device 21 is provided on the mounting frame 2 on the side of the height-adjusting hydraulic cylinder 9. The hydraulic oil supply device 21 is connected to the hydraulic shear 17 via a pipeline. Because the hydraulic shear 17 requires a large hydraulic pressure, a separate hydraulic oil supply device 21 is provided to provide the required hydraulic pressure.

[0026] Both the vertical mounting frame 6 and the rear end of the mounting frame 2 are equipped with lifting lugs 22 to facilitate the hoisting of the entire automatic anchor bolt shearing device.

[0027] The actuator frame 12 is composed of front, rear, left, and right side plates that are fixedly connected to each other. A length-adjusting hydraulic cylinder 15 is provided along the length of the front side plate and the left and right side plates. The push rod head of the length-adjusting hydraulic cylinder 15 is connected to the connector 16. A reinforcing plate 23 is slidably engaged inside each of the left and right side plates. The reinforcing plate 23 is provided along the length direction of the actuator frame 12. The head of the reinforcing plate 23 passes through the front side plate and is fixedly connected to the side of the connector 16. Because the connector 16 and the hydraulic shear 17 have a certain mass, in order to prevent the push rod of the length-adjusting hydraulic cylinder 15 from bending under the weight of the connector 16 and the hydraulic shear 17 after it is pushed out, the reinforcing plate 23 is provided to improve the bending resistance of the push rod of the length-adjusting hydraulic cylinder 15.

[0028] The reinforcing plate 23 has 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 extends to a long length.

[0029] A bottom support plate 24 is horizontally arranged between the middle side walls of the vertical mounting frame 6. 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 rods 7. When the height adjustment hydraulic cylinder 9 moves downward, the movable seat 8 is supported on the bottom support plate 24. The bottom support plate 24 supports the entire movable seat 8 and its upper structure. The bottom support plate 24 transmits the pressure it bears to the vertical mounting frame 6, and then 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 adjustment hydraulic cylinder 9 does not bear pressure, thereby improving the service life of the height adjustment hydraulic cylinder 9.

[0030] The walking base 1 is a tracked walking base, which is more suitable for the uneven ground environment of mine roadways.
