Description

Technical Field

[0001] This invention relates to the field of tunnel floor modification technology, and in particular to a rapidly movable tunnel floor leveling device and method. Background Technology

[0002] In coal mining, uneven roadway floors have always been a significant factor affecting mine safety and production efficiency. In some cases, deformation, bulging, or subsidence of the roadway floor can damage transportation equipment such as mine cars and conveyor belts, while also impacting the working efficiency of mining machinery. Therefore, developing a rapidly movable roadway floor leveling device is essential.

[0003] Existing methods for repairing tunnel floors have many shortcomings. The repair process requires a significant amount of manual labor, resulting in low efficiency and increasing worker workload and safety risks. Furthermore, while some repair equipment, such as tunnel repair machines and anchoring drills, is widely used in floor repair, these devices also present problems in practice. For example, they often require the use of multiple construction methods and process specifications to complete the repair work, and the coordination between different pieces of equipment and trades is often insufficient, leading to disorganized construction. Moreover, existing repair equipment has not been organically integrated with tunnel floor repair processes, resulting in high idle rates for some equipment, complex procedures, and an inability to meet repair needs under various complex conditions. This also leads to low equipment utilization and resource waste.

[0004] Therefore, there is an urgent need to develop a new type of rapid leveling device for coal mine roadway floor slabs to improve the speed of coal mine roadway floor slab repair construction, improve the working environment, reduce construction costs, and increase construction safety. Summary of the Invention

[0005] The purpose of this invention is to provide a leveling device and method for rapidly moving and modifying uneven roadway floors, so as to achieve efficient and rapid repair of uneven roadway floors and meet the repair needs under various complex conditions.

[0006] The present invention provides a rapidly movable roadway floor leveling device and method, comprising a high-strength steel plate, an electric hydraulic jack, rubber wheels, a rigid diverter plate, a release hook, and an electric hydraulic control system;

[0007] The high-strength steel plate serves as the flattening surface of the rapidly movable tunnel floor leveling device.

[0008] Among them, small-sized high-strength steel plates are hinged at both ends of the high-strength steel plate as pads;

[0010] The electric hydraulic jacks are rigidly connected to the high-strength steel plate, and the electric hydraulic jacks are connected to each other through hydraulic control wires.

[0011] The rubber wheel is mounted on the bottom of the high-strength steel plate, and the rubber wheel and the electric hydraulic jack are positioned in front of and behind each other.

[0012] The height of the rubber wheel is higher than the height of the electric hydraulic jack when it is not in operation;

[0013] The rigid diverter plate is placed on the front and rear sides of the bottom of the high-strength steel plate, and the thickness of the rigid diverter plate is lower than the height of the rubber wheel;

[0014] The rigid diversion plate is triangular in shape, with its front tip extending beyond the high-strength steel plate and closely attached to the bottom of the high-strength steel plate.

[0015] The unhooking device is located at the front and rear ends of the high-strength steel plate;

[0016] The electro-hydraulic control system includes a split-type electro-hydraulic controller, a hydraulic control valve, and hydraulic control wires. The split-type electro-hydraulic controller is disposed on one side of the top of the high-strength steel plate, and the hydraulic control valve is disposed on one side of the bottom of the high-strength steel plate, arranged vertically above the split-type electro-hydraulic controller.

[0017] The split-type electro-hydraulic controller is directly connected to the hydraulic control valve, and the hydraulic control valve is connected to the electro-hydraulic jack through the hydraulic control wire.

[0018] The present invention also provides a method for leveling the floor of a roadway that can be moved quickly, which uses the quick-moving roadway floor leveling device described in the aforementioned technical solution.

[0019] The method for leveling the floor of a rapidly movable tunnel includes the following steps:

[0020] S1: Determine the location where the tunnel floor shows deformation, bulging, or subsidence;

[0022] S3: Adjust each electric hydraulic jack to a suitable height using a split-type electric hydraulic controller according to the condition of the base plate to ensure that the high-strength steel plates are at the same horizontal level.

[0023] S4: Check whether the force on each electric hydraulic jack base is uniform. If the force is uneven, adjust the electric hydraulic jacks individually using the split electric hydraulic controller.

[0024] S5: Place the high-strength steel plate with hinged ends on the front and rear ends as a pad to complete the leveling of the tunnel floor.

[0036] Reference Figures 1 to 4 This invention provides a rapid and movable roadway floor leveling device, comprising:

[0037] High-strength steel plates are used as the leveling surface of a fast-moving roadway floor leveling device to level deformed roadway floors.

[0038] An electric hydraulic jack is installed at the bottom of the high-strength steel plate and rigidly connected to the high-strength steel plate. The electric hydraulic jack is connected to the hydraulic control valve through a hydraulic control wire.

[0039] The rubber wheel is mounted on the bottom of a high-strength steel plate and is located in front of the electric hydraulic jack. The height of the rubber wheel is higher than the height of the electric hydraulic jack when it is not in operation.

[0040] A rigid diverter plate is installed on the front and rear sides of the bottom of a high-strength steel plate. The thickness of the rigid diverter plate is lower than the height of the rubber wheel. The rigid diverter plate is triangular in shape, with the front tip extending beyond the high-strength steel plate and closely attached to the bottom of the high-strength steel plate.

[0041] The hook is installed at the front and rear ends of a high-strength steel plate and is connected to the traction equipment during movement.

[0042] The electro-hydraulic control system includes a split-type electro-hydraulic controller, a hydraulic control valve, and hydraulic control wires. The split-type electro-hydraulic controller is located on the top side of the high-strength steel plate, and the hydraulic control valve is located on the bottom side of the high-strength steel plate.

[0043] It should be noted that the number of rubber wheels and electric hydraulic jacks is not fixed and can be determined based on the load capacity and size of the leveling device.

[0044] It should be noted that the rigid diversion plate is triangular in shape and its front tip must extend beyond the high-strength steel plate to ensure that obstacles can be broken up and cleared and diverted during the movement of the leveling device.

[0045] It should be noted that the split-type electro-hydraulic controller is directly connected to the hydraulic control valve, which is connected to each electro-hydraulic jack via hydraulic control wires.

[0046] It is worth noting that the split-type electro-hydraulic controller can adjust the height of the electro-hydraulic jack individually through the hydraulic control valve.

[0047] It should be noted that the split-type electro-hydraulic controller and the hydraulic control valve must be installed on the same side of the high-strength steel plate. Figure 1 In the embodiment shown, both the split-type electro-hydraulic controller and the hydraulic control valve are arranged on the left side of the high-strength steel plate.

[0048] In addition, embodiments of the present invention also provide a method for rapid and movable roadway floor leveling, using the aforementioned rapid and movable roadway floor leveling device, including but not limited to the following steps:

[0049] S1: Determine the location where the tunnel floor shows deformation, bulging, or subsidence;

[0050] S2: Use the traction device to pull the leveling device to the position that needs to be leveled by unhooking;

[0051] S3: Adjust each electric hydraulic jack to the appropriate height using the split-type electric hydraulic controller according to the deformation of the base plate. After adjustment, ensure that the high-strength steel plates are at the same horizontal height.

[0052] S4: Check whether the base of each electric hydraulic jack is evenly stressed and can stably support the high-strength steel plate. If the stress is uneven, adjust the electric hydraulic jacks individually using the split electric hydraulic controller.

[0053] S5: Place the high-strength steel plate with hinged ends on the front and rear ends as a pad to complete the leveling of the tunnel floor.

[0054] It should be noted that in step S2, a traction device such as a trackless or tracked rubber-tired vehicle can be used to pull the base plate leveling device to the position where the base plate is deformed.

[0055] It should be noted that in step S3, the height of each electric hydraulic jack needs to be adjusted separately using a split-type electric hydraulic controller according to the deformation of the base plate, so as to ensure that the high-strength steel plates are on the same horizontal plane.

[0056] It should be noted that in step S4, it is necessary to ensure that each electric hydraulic jack base is in a suitable position and is subjected to uniform force so as to stably support the high-strength steel plate.

[0057] It should be noted that in step S5, after the position and height of the bottom plate leveling device are adjusted, the pads hinged on the front and rear sides of the high-strength steel plate are unfolded, and the bottom plate leveling device and the tunnel bottom plate are connected through the pads.

[0058] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
