Technical Field

[0001] The utility model relates to an automatic wood covering and releasing device for a scraper, in particular to an automatic wood covering and releasing device for a scraper, and belongs to the technical field of scrapers. Background Art

[0002] The scraper is a type of trackless mining equipment, which is widely used in mining and transportation in underground mines. The scraper includes wheels, traction beams, frames, hydraulic devices, buckets with shoveling mechanisms, bracket mechanisms, and frame lifting and adjustment mechanisms. The development of scrapers has a history of hundreds of years. The scraper can have both shoveling and transportation functions at the same time, especially when the transportation distance is between 200 to 300 meters and 1 to 2 kilometers, its operating economic efficiency is significantly better than the construction efficiency of other mechanical combinations. After the scraper stops, put the cover wood close to the wheels to cover the car.

[0003] The scraper in the prior art has the following disadvantages: 1. When the scraper is parked, people often have to manually move the cover wood to cover the vehicle, which is inconvenient to use; 2. The cover wood is usually made of solid wood, which is easily damaged after repeated use and has a short service life. Therefore, improvements are made to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic wood cover retracting and releasing device for a scraper in order to solve the above-mentioned problem. The electromagnet, spring and hydraulic cylinder cooperate to automatically retract and release the wood cover, and people do not need to manually install the wood cover; the reinforcing plate, reinforcing net, inner plate and the like cooperate to improve the overall strength and rigidity of the wood cover and extend its service life.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: an automatic wood covering and retracting device for a scraper loader comprises a base, an electromagnet is installed at the bottom end of the base, the electromagnet is located above a magnetic block, the magnetic block is installed above a retracting frame, the retracting frame is slidably connected with a slide bar, the slide bar is surrounded by a spring, the retracting frame is installed with a hydraulic cylinder, the hydraulic cylinder is installed with a covering wood, the covering wood is bonded with a reinforcing net, the reinforcing net is bonded with a reinforcing plate, the covering wood comprises a panel, an inner plate and a core plate, the inner plates are bonded on both sides of the core plate, and the inner plate is bonded with a panel.

[0006] Preferably, the base is mounted with a vehicle body, and the vehicle body is provided with wheels.

[0007] Preferably, the wheel is located on the inner side of the retractable frame, and the retractable frame is fixedly connected with a lug.

[0008] Preferably, the lug is slidably connected to a slide rod, the slide rod is installed below the base, and the lug is located below the spring.

[0009] Preferably, the cover wood is installed with a limit rod, the limit rod is slidably connected to the retractable rack, and the cover wood is slidably connected to the retractable rack.

[0010] Preferably, the reinforcing plate is made of POM plastic, and the reinforcing net is made of aramid.

[0011] Preferably, the inner panel is made of polyetheretherketone, and the core panel is made of high-impact polystyrene.

[0012] The beneficial effects of the utility model are:

[0013] 1. The electromagnet, spring and hydraulic cylinder cooperate to automatically retract and extend the cover wood, and people do not need to install the cover wood manually; a retracting frame is provided at the base at the bottom of the vehicle body, and the retracting frame is located on both sides of the wheel. After parking, the electromagnet installed at the base is powered off, and the attraction between the electromagnet and the magnetic block disappears. The compressed spring wants to restore its original state and pushes the lug on the retracting frame to slide downward along the slide bar, that is, pushes the retracting frame down to touch the ground, etc. After it touches the ground, the hydraulic cylinder on the retracting frame extends, and the hydraulic cylinder extends to push the connected cover wood to move inward, and the cover wood moves inward. The movement drives the connected limit rod to slide along the retractable frame, and the cover wood on both sides continuously moves inward under the action of the hydraulic cylinder and is close to the two sides of the wheel, so that the wheel can be covered in both directions. When the vehicle is driving, the hydraulic cylinder shortens and drives the connected cover wood to slide outward and be retracted into the retractable frame. After the cover wood is separated from the wheel, the electromagnet at the bottom of the base generates magnetism after being energized, which generates a large attraction to the magnetic block on the retractable frame below, and can drive the retractable frame to move upward, so that the magnetic block is close to the electromagnet, and the cover wood can be retracted and released through the cooperation of the electromagnet, spring and hydraulic cylinder.

[0014] 2. The reinforcement board, reinforcement net, inner board, etc. are used to improve the overall strength and rigidity of the mask wood and extend its service life. The mask wood is composed of a composite panel, inner board and core board. The material of the inner board is polyetheretherketone, which has good toughness and rigidity, impact resistance and excellent dimensional stability. The material of the core board is high-impact polystyrene, which has high impact strength and high rigidity. Micron-level rubber particles are added to the core board and the polystyrene and rubber particles are connected together by grafting. When impacted, the tip stress of the crack extension will be released by the relatively soft rubber particles, which has good impact resistance. The mask wood surface is bonded with a reinforcement net made of aramid, which has excellent properties such as ultra-high strength, high modulus and light weight. Its strength is 5 to 6 times that of steel wire, its modulus is 2 to 3 times that of steel wire or glass fiber, and its toughness is 2 times that of steel wire. The surface of the reinforcement net is bonded with a reinforcement board made of POM plastic, which has high mechanical strength and rigidity, good impact resistance, and the reinforcement board, inner board and core board are used to improve the overall strength and rigidity and extend its overall service life.
