Description

TECHNICAL FIELD

[0001] The utility model relates to a dredging anti-suction technology field, specifically a horizontal lifting device for slag dredging robot anti-suction. BACKGROUND

[0002] Slag dredging mainly refers to the operation of cleaning the waste slag accumulation generated in the process of mining, ore dressing or smelting, and the core purpose is to eliminate the safety hazards caused by slag accumulation, reduce the pollution to soil and water, and restore the normal function of the site. This operation is often seen in slag accumulation areas around mines, tailings ponds or smelting plants, and part of the slag can be reused after treatment. The overall process focuses on efficiency and environmental protection, which not only ensures production safety, but also helps ecological restoration.

[0003] The existing dredging robot is driven to walk by a belt because the belt has a larger contact area than the tire. However, due to the lack of automatic anti-deviation structure for the belt in the existing device, when the robot moves in the complex terrain of slag accumulation, the belt will gradually deviate to one side due to the influence of lateral force or uneven tension. If not corrected in time, the deviation will continue to expand, accelerating the wear and even tearing of the belt, shortening the service life. At the same time, the deviation of the belt will destroy the symmetry of the drive system, causing imbalance between the left and right sides. In view of this, we provide a horizontal lifting device for slag dredging robot anti-suction. SUMMARY

[0004] The purpose of the utility model is to make up for the shortcomings of the prior art, and provide a horizontal lifting device for slag dredging robot anti-suction.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a horizontal lifting device for slag dredging robot anti-suction, comprising a working machine, a plurality of belt pulleys are rotatably connected to the outer walls of the working machine on both sides, and a plurality of clamping teeth are fixedly connected to the outer walls of the belt pulleys, a plurality of driving belts are fixedly connected to the outer walls of the working machine on both sides, a plurality of deviation correction tooth grooves are formed in the inner walls of the driving belts, a plurality of limiting walls are additionally provided on both sides of the inner walls of the driving belts, and a plurality of anti-skid teeth are additionally provided on the outer walls of the driving belts. A top rod and a low rod are fixedly connected to one side of the inside of the working machine, a plurality of top end connecting rods and bottom end connecting rods are rotatably connected to both ends of the outer walls of the top rod and the low rod, a dredging equipment is rotatably connected to the outer walls of the top end connecting rods and the bottom end connecting rods through a rotating shaft, a plurality of hydraulic telescopic rods are rotatably connected to both ends of the outer walls of the top end connecting rods, and the telescopic ends of the hydraulic telescopic rods are rotatably connected to one side of the bottom of the bottom end connecting rods through a rotating shaft.

[0006] The clamping teeth and the deviation correction tooth grooves on the outer walls of the clamping teeth and the inner walls of the deviation correction tooth grooves correspond to each other and are engaged with each other.

[0007] The plurality of limiting walls and the outer walls of the clamping teeth are both provided with a rounded corner.

[0008] The plurality of limiting walls are respectively located on both sides of the outer wall of the clamping teeth, and one side of the outer wall of the limiting wall is attached to the outer wall of the clamping teeth.

[0009] The outer wall of the plurality of top end connecting rods and bottom end connecting rods is rotatably connected to the outer wall of the dredging equipment on both sides through a rotating shaft at one end.

[0010] The distance between the two ends of the plurality of top end connecting rods and bottom end connecting rods is equal.

[0011] The bending angle of the plurality of top end connecting rods and bottom end connecting rods is 150°, and the plurality of top end connecting rods, bottom end connecting rods and hydraulic telescopic rods are symmetrically arranged on both sides of the outer wall of the dredging equipment.

[0012] Compared with the prior art, the anti-vacuum horizontal lifting device for the slag dredging robot has the following beneficial effects:

[0013] First, the limiting wall is added on both sides of the inner wall of the driving belt and attached to the outer wall of the clamping teeth, so that when the robot moves in the complex terrain of slag accumulation, even if the driving belt is affected by lateral force or uneven tension and tends to deviate, the limiting wall will immediately form a horizontal constraint with the outer wall of the clamping teeth, limiting the driving belt to the center transmission position of the pulley, avoiding continuous deviation to one side, achieving real-time limiting, and without manual intervention, the lateral interference caused by the terrain can be automatically offset, reducing the risk of expansion of the deviation from the source, and at the same time, the rounded corners of the limiting wall and the outer wall of the clamping teeth can stably constrain the driving belt in the correct position, making the moving track of the device more consistent with the predetermined route, avoiding frequent direction adjustment caused by driving imbalance, and further improving the operation efficiency and stability.

[0014] Second, the top rod and the low rod are rotatably connected to the dredging equipment through the top end connecting rod and the bottom end connecting rod, and the distance between the two ends of the top end connecting rod and the bottom end connecting rod is equal, and the bending angle of 150° and the symmetric arrangement of the two can form a stable parallel four-bar linkage mechanism, so that when the hydraulic telescopic rod is extended or retracted, the top end connecting rod and the bottom end connecting rod are synchronously linked to drive the dredging equipment to stably ascend and descend, ensuring that the posture is always perpendicular to the ground during the lifting process, avoiding the suction inlet of the slag pump from being separated from the liquid surface and the suction phenomenon caused by angle deviation.

[0015] Other advantages, objects and features of the present application will be set forth in part in the following specification, and in part will be apparent from the examination of the following specification, or can be learned from the practice of the present application without undue experimentation.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] As Figures 1-6As shown, the utility model provides a technical scheme: a kind of for mineral slag dredging robot anti-suction empty horizontal lifting device, including working machine 1, the both sides of the outer wall of working machine 1 are rotatably connected with multiple belt pulleys 2, and multiple claws 201 are fixedly connected to the outer wall of belt pulley 2, the both sides of the outer wall of working machine 1 are fixedly connected with multiple driving belts 202, and multiple deviation correction tooth grooves 203 are opened in the inner wall of driving belt 202, multiple limit walls 204 are additionally provided on the both sides of the inner wall of driving belt 202, and multiple anti-skid teeth 205 are additionally provided on the outer wall of driving belt 202, one side of the inside of working machine 1 is fixedly connected with top rod 3 and low rod 301, and multiple top end connecting rods 302 and bottom end connecting rods 303 are rotatably connected to the both ends of the outer wall of top rod 3 and low rod 301 respectively, cleaning equipment 304 is rotatably connected to the outer wall of one end of top end connecting rod 302 and bottom end connecting rod 303 by shaft, and multiple hydraulic telescopic rods 305 are rotatably connected to the both ends of the outer wall of top end connecting rod 302, and the telescopic end of hydraulic telescopic rod 305 is rotatably connected to the bottom side of bottom end connecting rod 303 by shaft.

[0025] Limit wall 204 is additionally provided on the both sides of the inner wall of driving belt 202 and adheres to the outer wall of claw 201, when robot moves in the complex terrain of mineral slag accumulation, even if driving belt 202 is affected by lateral force or tension uneven and generates deviation tendency, limit wall 204 will immediately form transverse constraint with the outer wall of claw 201, driving belt 202 is limited in the center transmission position of belt pulley 2, avoids its continuous deviation to one side, realizes real-time limiting, and does not need manual intervention, can automatically offset lateral interference brought by terrain, reduces the risk of deviation amount expansion from source, simultaneously, the round corner of limit wall 204 and the outer wall of claw 201 can stably constrain driving belt 202 in correct position.

[0026] As Figure 2 Shown, the inner wall of deviation correction tooth groove 203 of the outer wall of claw 201 corresponds to each other, and the inner wall of deviation correction tooth groove 203 of the outer wall of claw 201 engages each other.

[0027] The corresponding engagement of claw 201 and deviation correction tooth groove 203 can make belt pulley 2 and driving belt 202 form mutual locking when transmission, avoid the sliding between driving belt 202 and belt pulley 2, and reduce the center line deviation of driving belt 202 and belt pulley 2 when moving.

[0028] As Figure 4 Shown, multiple limit walls 204 and the outer wall of claw 201 are all provided with round corner.

[0029] The round corner of limit wall 204 and the outer wall of claw 201 can push driving belt 202 back to correct position through the transverse constraint generated by round corner limit wall 204 and claw 201 in the initial stage of deviation of driving belt 202, to prevent deviation amount from continuously expanding.

[0030] AsFigure 2 As shown, the outer walls of multiple limiting walls 204 are located on both sides of the outer wall of the tooth 201, and one side of the outer wall of the limiting wall 204 is in contact with the outer wall of the tooth 201.

[0031] The limiting wall 204 is closely attached to both sides of the outer wall of the tooth 201, which can form a lateral limit on the drive belt 202 when it is running, and further prevent the drive belt 202 from shifting to the left and right sides due to uneven force.

[0032] like Figure 5 As shown, one end of the outer wall of multiple top connecting rods 302 and bottom connecting rods 303 is rotatably connected to both sides of the outer wall of the dredging equipment 304 via rotating shafts.

[0033] The top connecting rod 302 and the bottom connecting rod 303 are rotatably connected to both sides of the outer wall of the dredging equipment 304 through a rotating shaft. This can distribute the weight of the dredging equipment 304, avoid structural deformation caused by excessive force on one side, and ensure the balance of the dredging equipment 304 during lifting and lowering, thus reducing swaying.

[0034] like Figure 6 As shown, the distance between the two ends of the multiple top connecting rods 302 and bottom connecting rods 303 is equal.

[0035] The distance between the two ends of the top connecting rod 302 and the bottom connecting rod 303 is equal, which can form a structure similar to a parallelogram, ensuring the horizontal posture of the dredging equipment 304 during lifting and lowering, and effectively preventing the occurrence of air suction.

[0036] like Figure 5 As shown, the bending angles of multiple top connecting rods 302 and bottom connecting rods 303 are all 150°, and the multiple top connecting rods 302, bottom connecting rods 303 and hydraulic telescopic rods 305 are arranged symmetrically on both sides of the outer wall of the dredging equipment 304.

[0037] The top connecting rod 302 and the bottom connecting rod 303 have a bending angle of 150°, which can provide sufficient extension space for the hydraulic telescopic rod 305 while ensuring the strength of the connecting rod, and avoid interference between the connecting rod and the hydraulic telescopic rod 305 during movement. At the same time, the symmetrical layout can ensure that the dredging equipment 304 maintains balance during the lifting process, further improving the stability of operation.

[0038] Working principle: the corresponding engagement of the clamping tooth 201 and the deviation tooth groove 203 can make the belt pulley 2 and the driving belt 202 form mutual locking during transmission, avoid the sliding between the driving belt 202 and the belt pulley 2, and reduce the center line deviation of the driving belt 202 during movement. The round corner of the limiting wall 204 and the outer wall of the clamping tooth 201 can drive the initial deviation of the driving belt 202, and the transverse constraint generated by the round corner limiting wall 204 and the clamping tooth 201 can push the driving belt 202 back to the correct position, prevent the continuous expansion of the deviation amount, and the limiting wall 204 is close to the outer wall of the clamping tooth 201 on both sides, which can form transverse limiting of the driving belt 202 during operation, further prevent the driving belt 202 from deviating to the left and right sides due to uneven force, and the top link 302 and the bottom link 303 are rotatably connected to the outer wall of the dredging equipment 304 on both sides through the rotating shaft, which can disperse the weight of the dredging equipment 304, avoid the structural deformation caused by excessive unilateral force, and ensure the balance of the dredging equipment 304 during lifting, reduce shaking, and the distance between the top link 302 and the bottom link 303 is equal, which can form a similar structure to the parallelogram, ensure the horizontal posture of the dredging equipment 304 during lifting, effectively prevent the occurrence of air suction phenomenon, and the top link 302 and the bottom link 303 have a bending angle of 150°, which can ensure the strength of the link while providing sufficient expansion space for the hydraulic telescopic rod 305, avoid interference between the link and the hydraulic telescopic rod 305 during movement, and the symmetrical layout can ensure the balance of the dredging equipment 304 during lifting, further improve the operation stability.
