Abstract
Description
Technical Field
[0001] This invention relates to the field of road repair technology, specifically to a slope leveling device for open-pit mine roads. Background Technology
[0002] In open-pit mining operations, road smoothness directly affects transportation efficiency, equipment safety, and operational continuity. Open-pit mining roads are mostly temporary, and are prone to undulations, potholes, and uneven slopes due to blasting operations, heavy vehicle traffic, and natural rainfall. Uneven road slopes not only increase fuel consumption and mechanical wear on transport vehicles but also may cause vehicles to skid or overturn due to road inclines, impacting the timeliness of material transportation and hindering overall production progress.
[0003] Existing open-pit mine road slope leveling devices mostly use fixed-angle leveling components when facing complex and variable slopes, which cannot be adjusted in real time according to the actual slope, resulting in poor leveling effect. For example, when encountering road sections where the slope suddenly becomes steep or gentle, the fixed-angle leveling components either fail to make sufficient contact with the road surface for effective leveling, or cut too deep into the road surface, damaging the existing road structure. Summary of the Invention
[0004] The purpose of this invention is to provide a slope leveling device for open-pit mine roads, thereby solving the problems existing in the background art.
[0005] The objective of this invention can be achieved through the following technical solutions: A slope leveling device for open-pit mine roads includes a support frame, a rotating shaft movably embedded in the middle of the support frame, and one end of the rotating shaft being securely connected to the top of the inner side of a leveling scraper. The top of the leveling scraper is equipped with an adaptive adjustment mechanism. The mechanism has a hydraulic chamber containing hydraulic oil inside and hydraulic cylinders fixed to and connected to the bottom of both sides. A push plate is slidably embedded in the hydraulic cylinder. The other end of the push column fixed to one side of the push plate passes through the hydraulic cylinder and is hinged to the surface of the leveling scraper. A suspension spring is also fixed between the push plate and the hydraulic chamber. When the leveling scraper tilts with the road slope, it pushes the push columns on both sides, causing the hydraulic oil in the hydraulic chamber to flow under the pressure of the push plates on both sides, thereby achieving adaptive adjustment of the leveling scraper and making it closely fit the road surface.
[0006] As a further aspect of the present invention: the adaptive adjustment mechanism further includes multiple storage cylinders axially fixed to the surface of the push plate, and a movable column with one end fixed to the inside of the hydraulic chamber is slidably inserted inside the storage cylinder.
[0007] As a further aspect of the present invention: the adaptive adjustment mechanism is equipped with a hydraulic compensation mechanism that can automatically replenish internal hydraulic oil.
[0008] As a further aspect of the present invention: the hydraulic compensation mechanism includes a storage compartment fixed to the top of the hydraulic chamber, which forms a hydraulic oil circulation with the interior of the hydraulic chamber through multiple liquid holes opened in the hydraulic chamber. A feed valve connected to the interior of the storage compartment is fixed in the middle for adding hydraulic oil.
[0009] As a further aspect of the present invention: the hydraulic compensation mechanism further includes a hopper fixedly connected in the storage compartment and in contact with the liquid hole, wherein a float ball that can be suspended on the surface of the hydraulic oil is slidably embedded in the hopper. A limiting rod is fixed to the inside of the float to restrict its upward movement; A positioning plate is fixedly connected to the storage compartment, and a connecting post with one end fixedly connected to the top of the float is slidably inserted through the middle of the positioning plate. A retraction spring is fitted onto the surface of the connecting column, located between the positioning plate and the float. A limit plate is fixed to the other end of the connecting column.
[0010] As a further aspect of the present invention: an auxiliary scraper is slidably embedded in the leveling scraper, and elastic columns that can slide in the sliding grooves on both sides of the auxiliary scraper are fixedly connected to both sides of the auxiliary scraper. A sliding block is fixedly connected between the elastic columns and the leveling scraper.
[0011] As a further embodiment of the present invention: a connecting frame is fixedly connected to the middle surface of the rotating shaft, and the two sides of the connecting frame are firmly connected to one side of the leveling scraper. A limiting mechanism is installed on one side of the support frame. The mechanism includes a protective block fixed to one side of the support frame and rotatably connected to a two-way lead screw on one side. A movable block that can slide in the groove of the protective block is threaded onto the surface of the two-way lead screw. A limiting block that can slide inside the protective block is fixed to one side of the movable block. A knob is also fixed to one end of the two-way lead screw.
[0012] As a further aspect of the invention, it also includes a mounting block, which is fixed to the tractor vehicle with bolts through connecting holes on both sides.
[0013] As a further embodiment of the present invention: a positioning block is fixedly connected to the inner side of the mounting block, a motor is fixedly connected to one side of the positioning block, the output end of the motor passes through one side of the positioning block, and a bevel gear one that meshes with bevel gear two is fixedly connected to it. A transmission column that can rotate in the middle of one side of the positioning block is fixedly connected to the middle of the second bevel gear; A protective shell for protecting the motor is fixed to one side of the positioning block.
[0014] As a further embodiment of the present invention: a positioning rod that can rotate on the surface of the positioning block is fixedly connected to the top surface of the transmission column, a moving rod is slidably inserted inside the positioning rod, a side block is fixedly connected to the other end of the moving rod, and a fixed block connected to one side of the hydraulic chamber is fixedly connected to the other end of the side block. The support frame is fixed to the bottom of the fixed block; A cylinder is fixedly connected to one side of the positioning rod, and the output end of the cylinder is fixedly connected to one side of the side block.
[0015] The beneficial effects of this invention are: (1) The present invention realizes the real-time angle adjustment of the leveling scraper through the adaptive adjustment mechanism. When the road slope suddenly becomes steep or gentle, the leveling scraper drives the push plate to squeeze the hydraulic oil through the push column, so that the hydraulic oil flows in both directions in the hydraulic chamber, drives the push plates on both sides to move in opposite directions synchronously, and then automatically corrects the scraper angle, thereby avoiding the disadvantages of insufficient contact or excessive cutting. It can ensure that the scraper is in close contact with the road surface to achieve effective leveling, and prevent damage to the existing road structure, thus significantly improving the leveling quality of complex road sections. (2) In this invention, the float in the storage compartment automatically opens and closes the hopper according to the change of hydraulic oil level in the hydraulic tank, replenishes the lost hydraulic oil in real time, and ensures that the hydraulic system always maintains stable pressure. This function avoids the adjustment delay or failure caused by insufficient oil, so that the equipment can continue to operate accurately on road sections with frequent changes in slope, reduce downtime caused by system failure, and ensure the continuity of road leveling in the mining area. (3) The cooperation between the auxiliary scraper and the elastic column of the present invention provides a guarantee for the detailed leveling of complex slope roads. When the main body of the leveling scraper has a local gap due to the sudden change of slope, the elastic column pushes the auxiliary scraper to slide along the groove, fills the gap and conforms to the undulation of the road surface. Especially in areas that are easily overlooked, such as slope turning points and road edges, it can effectively avoid the problem of missing leveling and further improve the adaptability of the device to complex terrain.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1 Please see Figures 1-10 As shown, the present invention is a slope leveling device for open-pit mining roads, including a support frame 1, a rotating shaft 3 movably embedded in the middle of the support frame 1, and one end of the rotating shaft 3 being securely connected to the top of the inner side of the leveling scraper 5. The top of the leveling scraper 5 is equipped with an adaptive adjustment mechanism 6. This mechanism has a hydraulic chamber 66 containing hydraulic oil inside and fixed to and connected to the bottom of the hydraulic cylinders 60 on both sides. A push plate 61 is slidably embedded in the hydraulic cylinder 60. The other end of the push column 62 fixed to one side of the push plate 61 passes through the hydraulic cylinder 60 and is hinged to the surface of the leveling scraper 5. A suspension spring 63 is also fixed between the push plate 61 and the hydraulic chamber 66. When the leveling scraper 5 tilts with the road slope, it pushes the push columns 62 on both sides, causing the hydraulic oil in the hydraulic chamber 66 to flow under the pressure of the push plates 61 on both sides, thereby realizing the adaptive adjustment of the leveling scraper 5 and making it closely fit the road surface.
[0021] Preferably, the adaptive adjustment mechanism 6 of the present invention further includes a plurality of storage cylinders 64 axially fixed to the surface of the push plate 61, and a movable column 65 having one end fixed to the inside of the hydraulic chamber 66 is slidably inserted inside the storage cylinder 64.
[0022] It should be noted that the hydraulic cylinder 60, push plate 61, push column 62, suspension spring 63, storage cylinder 64, and moving column 65 are all provided in two sets and are respectively located on both sides of the hydraulic chamber 66, so as to facilitate the synchronous pushing of the hydraulic oil in the hydraulic chamber 66.
[0023] Preferably, the adaptive adjustment mechanism 6 is equipped with a hydraulic compensation mechanism 7 that can automatically replenish the internal hydraulic oil.
[0024] Preferably, in this invention, the hydraulic compensation mechanism 7 includes a storage compartment 70 fixed to the top of the hydraulic chamber 66, which forms a hydraulic oil circulation with the interior of the hydraulic chamber 66 through a plurality of liquid holes 67 opened in the hydraulic chamber 66. A feed valve 71, which communicates with the interior of the storage compartment 70, is fixedly connected to the middle of the compartment for adding hydraulic oil.
[0025] Preferably, in this invention, the hydraulic compensation mechanism 7 further includes a hopper 72 fixedly connected in the storage chamber 70 and in contact with the liquid hole 67, and a float ball 73 that can be suspended on the surface of the hydraulic oil is slidably embedded in the hopper 72. A limiting rod 74 is fixedly connected to the inside of the float 73 to restrict its upward movement; A positioning plate 75 is fixedly connected inside the storage compartment 70, and a connecting post 76 with one end fixedly connected to the top of the float 73 is slidably passed through the middle of the positioning plate 75. A retraction spring 77 is fitted on the surface of the connecting column 76 between the positioning plate 75 and the float 73; The other end of the connecting column 76 is fixedly connected to the limiting plate 78.
[0026] It should be noted that the limiting rod 74 is designed to prevent the float 73 from moving upwards, thereby preventing hydraulic oil from dripping from the gap between the float and the hopper 72. The limiting plate 78 effectively prevents the connecting column 76 from detaching from the positioning plate 75; The center diameter of the float 73 is the same as the top diameter of the hopper 72, and the float 73 is made of elastic material with a certain shrinkage property, which makes it easy to block the top of the hopper 72. Multiple sets of hydraulic oil are provided for the hydraulic chamber 66, including the liquid hole 67, hopper 72, float ball 73, limiting rod 74, positioning plate 75, connecting column 76, retraction spring 77, and limit plate 78, to facilitate the replenishment of hydraulic oil inside the hydraulic chamber 66. The spring force of the contraction spring 77 is less than the buoyancy of the hydraulic oil.
[0027] During implementation, as the leveling scraper 5 changes with the road slope during its pushing process, the leveling scraper 5 rotates and tilts along the middle of the support frame 1 via the connecting frame 2 and the rotating shaft 3. The leveling scraper 5 tilts and pushes one of the sets of pushing columns 62 on one side of the surface. The pushing column 62 moves the push plate 61 upward along the inside of the hydraulic cylinder 60. The push plate 61 pushes the storage cylinder 64 and the suspension spring 63. The suspension spring 63, the storage cylinder 64, and the moving column 65 retract. The push plate 61 pushes the hydraulic oil inside the hydraulic chamber 66, causing the hydraulic oil to move to the other side of the hydraulic chamber 66 and push the surface of another set of push plates 61. The other set of push plates 61, pushed by the hydraulic oil, moves the pushing column 62 downward along one side of the hydraulic cylinder 60 and pushes the other side of the leveling scraper 5. This ensures that the leveling scraper 5 maintains a level slope with the ground slope when tilted, and is close to the ground by the push of the hydraulic oil inside the hydraulic chamber 66, maintaining a stable fit. When the hydraulic oil inside the hydraulic chamber 66 is damaged and consumed, the float 73 moves downward along the inside of the hopper 72 according to the decrease of the hydraulic oil in the hydraulic chamber 66 and the thrust of the retraction spring 77. The float 73 moves downward along the hopper 72, so that the hydraulic oil in the storage chamber 70 flows into the hydraulic chamber 66 through the gap between the float 73 and the hopper 72 from the liquid hole 67 to replenish the hydraulic oil inside. When the hydraulic oil in the hydraulic tank 66 rises, the float 73 rises with the liquid level and eventually blocks the inlet of the hopper 72 completely through the limit rod 74, preventing hydraulic oil from entering again.
[0028] Example 2 Preferably, in this invention, an auxiliary scraper 21 is slidably embedded in the leveling scraper 5, and elastic columns 23 that can slide in the sliding grooves on both sides of the auxiliary scraper 21 are fixedly connected to both sides of the auxiliary scraper 21. A sliding block 22 is fixedly connected between the elastic column 23 and the leveling scraper 5.
[0029] It should be noted that the elastic column 23 has a certain degree of elasticity, which facilitates pushing the sliding block 22, so that the sliding block 22, along with the auxiliary scraper 21, moves downward along the inside of the leveling scraper 5 for compensation. During implementation, when the leveling scraper 5 comes into contact with the ground, the auxiliary scraper 21, driven by the elastic column 23, moves the sliding block 22 downward along the leveling scraper 5 to closely adhere to the road surface, thereby compensating for the gap between the leveling scraper 5 and the road.
[0030] Example 3 Preferably, in this invention, a connecting frame 2 is fixedly connected to the middle surface of the rotating shaft 3, and the two sides of the connecting frame 2 are firmly connected to one side of the leveling scraper 5; A limiting mechanism 4 is installed on one side of the support frame 1. The mechanism includes a protective block 40 fixed to one side of the support frame 1 and rotatably connected to a bidirectional lead screw 41 on one side. A movable block 42 that can slide in the groove of the protective block 40 is threaded on the surface of the bidirectional lead screw 41. A limiting block 43 that can slide in the protective block 40 is fixed to one side of the movable block 42. A knob 44 is also fixed to one end of the bidirectional lead screw 41.
[0031] It should be noted that the bidirectional lead screw 41 has a partition block in the middle and two sets of symmetrically arranged thread groups are set with the partition block as the boundary. Both the moving block 42 and the limiting block 43 are provided in two sets, and both sets of moving blocks 42 are threadedly connected to the surfaces of the two sets of threaded groups. The inner side of the limiting block 43 is provided with anti-slip texture (not shown) to facilitate the rotation limiting of the rotating shaft 3.
[0032] During implementation, when the angle of the leveling scraper 5 does not need to be adjusted and is locked, the knob 44 is turned. The knob 44 rotates the bidirectional lead screw 41. The rotation of the bidirectional lead screw 41 causes the moving blocks 42 on the surface to move inward along the sliding groove inside the bidirectional lead screw 41 and the protective block 40. Both sets of moving blocks 42 move inward with the limiting block 43, thereby locking the central rotating shaft 3 and preventing the rotating shaft 3 from rotating.
[0033] Example 4 Preferably, the present invention also includes a mounting block 15, which is fixed to the tractor by bolts through connecting holes on both sides.
[0034] Preferably, in this invention, a positioning block 14 is fixedly connected to the inner side of the mounting block 15, a motor 17 is fixedly connected to one side of the positioning block 14, the output end of the motor 17 passes through one side of the positioning block 14, and a bevel gear 18 that meshes with the second bevel gear 19 is fixedly connected to it. A transmission column 20 that can rotate in the middle of one side of the positioning block 14 is fixedly connected to the middle of the bevel gear 19; A protective shell 16 for protecting the motor 17 is fixedly attached to one side of the positioning block 14.
[0035] Preferably, in this invention, a positioning rod 11 that can rotate on the surface of the positioning block 14 is fixedly connected to the top surface of the transmission column 20, a moving rod 12 is slidably passed through the positioning rod 11, a side block 10 is fixedly connected to the other end of the moving rod 12, and a fixing block 9 connected to one side of the hydraulic chamber 66 is fixedly connected to the other end of the side block 10. Support frame 1 is fixedly connected to the bottom of fixed block 9; A cylinder 13 is fixedly connected to one side of the positioning rod 11, and the top output end of the cylinder 13 is fixedly connected to one side of the side block 10.
[0036] In the implementation process, the entire device is first fixed to the front end of the tractor (such as a trolley, forklift, or tractor) through the mounting holes opened on the surface of the mounting block 15. When the leveling scraper 5 needs to be adjusted in height, a cylinder 13 is set up. The output end of the cylinder 13 pushes the side block 10. The side block 10, along with the moving rod 12, moves upward along the inside of the positioning rod 11. The side block 10, along with the fixing block 9, hydraulic chamber 66, suspension spring 63, push plate 61, push column 62 and leveling scraper 5, moves upward to adjust the height. When the angle needs to be adjusted, motor 17 is set up. The output end of motor 17 drives bevel gear 18 to rotate. Bevel gear 18 drives bevel gear 29 to rotate along the inside of positioning block 14. Bevel gear 29 drives transmission column 20 to rotate along the inside of positioning block 14. Positioning block 14 drives positioning rod 11 to rotate. Positioning rod 11 drives moving rod 12 and side block 10 to rotate. Side block 10 drives fixed block 9, adaptive adjustment mechanism 6, suspension spring 63, push plate 61, push column 62 and leveling scraper 5 to rotate and adjust the angle.

All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
