Description

Technical Field

[0001] The invention belongs to the technical field of steel bar cutting, and specifically refers to a steel bar cutting device for water conservancy and hydropower construction. Background Art

[0002] During the construction process of water conservancy and hydropower projects, the steel bar cutting process is often involved. Especially for the dam body of a water conservancy project, due to the high waterproof level, during the construction and pouring of the dam, water-stop screw steel bars are usually used for formwork fixing. After the dam structure solidifies, it is necessary to cut off the water-stop screw steel bar heads protruding outside the side wall of the dam body. In the prior art, manual work is mostly combined with hanging baskets and gangplanks for operation, which has many technical problems.

[0003] Most of the steel bar cutting devices in the prior art for water conservancy and hydropower construction are for the steel bar processing stage and are applicable to steel bar processing sheds, and cannot be applied to the cutting of embedded water-stop screw steel bars on the outer wall of the dam.

[0004] Due to the position deviation of the embedded water-stop screw steel bars, and the clamping and cutting instruments usually need to align the embedded water-stop screw steel bars, it is difficult to clamp and cut them through automatic clamping instruments. When manually cutting the heads of the embedded water-stop screw steel bars, not only is the efficiency low, but it is also very dangerous. Because the dam body is usually tall, manual work at high altitudes is required, and the water-stop screw steel bar heads are very dense. When manually cutting, it is difficult to walk and perform cutting operations, and the efficiency is very low. At the same time, the cut water-stop screw steel bar heads are likely to directly fall to the bottom of the dam, and there is also a risk of falling objects from a height. Summary of the Invention

[0005] In view of the above technical problems, the invention provides a steel bar cutting device for water conservancy and hydropower construction, which creatively designs a cutting manipulator. By using a clever two-way hydraulic circuit design, the two groups of adaptive clamping parts can perform asymmetric movements, and only by means of the touch and pressing action of the cross beam and the water-stop screw steel bars, the water-stop screw steel bars in any area covered by the cross beam can be reliably and adaptively clamped. It also uses the hydraulic change generated by the clamping action to realize the automatic cutting of the water-stop screw steel bars, significantly improving the cutting efficiency. Before and after cutting, the water-stop screw steel bars can be reliably clamped and safely recycled, avoiding the risk of falling objects from a height.

[0006] The technical solution adopted by the present invention is as follows: This solution provides a steel bar cutting device for water conservancy and hydropower construction, which consists of a wall-climbing vehicle and a cutting manipulator. The cutting manipulator is rotatably connected to the upper end of the wall-climbing vehicle. A steering motor is fixedly connected to the upper wall of the wall-climbing vehicle, and a steering gear is fixedly connected to the output shaft of the steering motor. The cutting manipulator includes a cross beam, an adaptive clamping member, a cutting assembly, and a power box. A steering shaft is fixedly connected to the lower wall of the cross beam, and the cross beam is rotatably connected to the upper wall of the wall-climbing vehicle through the steering shaft. The adaptive clamping member is slidably arranged on the cross beam, and there are two groups of adaptive clamping members. The cutting assembly is arranged on one group of adaptive clamping members, and the power box is arranged on the lower wall of the cross beam. A hydraulic transmission is provided between the power box and the adaptive clamping member, and a transmission is provided between the cutting assembly and the adaptive clamping member. A driven gear is coaxially and fixedly connected to the steering shaft, and the driven gear meshes with the steering gear. The cross beam and the wall-climbing vehicle are meshed and driven through the engagement of the driven gear and the steering gear. Wall-climbing power wheels are symmetrically arranged on the side wall of the wall-climbing vehicle, and a wall-climbing belt is wound around the wall-climbing power wheels on the same side. A receiving hopper is fixedly connected to the outer side wall of the wall-climbing vehicle.

[0007] In this solution, a touch beam is slidably arranged on the upper wall of the cross beam, and a rack is arranged on the upper wall of the cross beam. The adaptive clamping member includes a clamping block, an impeller chamber, and a clamping gear. The clamping block is horizontally slidably clamped to the side wall of the cross beam, the impeller chamber is fixedly arranged on the side wall of the clamping block, a two-way impeller is rotatably arranged on the inner wall of the impeller chamber, the clamping gear is rotatably arranged on the outer wall of the impeller chamber, the clamping gear is coaxially and fixedly connected to the two-way impeller, and the clamping gear is engaged with the rack. The two-way impeller is transmitted with the cross beam through the engagement of the impeller chamber, the clamping gear, and the rack. The two-way impeller drives the clamping gear to rotate, so that the clamping block slides along the side wall of the cross beam. A liquid flow pipe one and a liquid flow pipe two are respectively arranged through the circumferential outer wall of the impeller chamber, and the liquid flow pipe one and the liquid flow pipe two penetrate through the clamping block.

[0008] As a further preference of this solution, a two-way gear pump is fixedly arranged on the inner wall of the power box. A hose is connected between the bottom wall of the power box and the bottom wall of the clamping block. The liquid flow pipe one and the liquid flow pipe two are laid along the inner wall of the hose. The ends of the liquid flow pipe one in the two adaptive clamping members far from the impeller chamber penetrate through the bottom wall of the power box and are communicated with one end of the two-way gear pump, and the ends of the liquid flow pipe two in the two adaptive clamping members far from the impeller chamber penetrate through the bottom wall of the power box and are communicated with the other end of the two-way gear pump.

[0009] In this solution, the cutting assembly includes a telescopic rod, a pushing piece, and a cutting motor. The base part of the telescopic rod is fixedly arranged on the side wall of the clamping block, the pushing piece is fixedly connected to the end of the push rod of the telescopic rod, the cutting motor is horizontally slidably arranged on the upper wall of the clamping block, a pressure pipe is communicated between the end of the base part of the telescopic rod and the middle part of the liquid flow pipe one, the pushing piece is obliquely transmitted with the cutting motor, and a cutting blade is connected to the output shaft of the cutting motor.

[0010] Furthermore, adsorption plates are symmetrically and fixedly arranged on both side walls of the wall-climbing vehicle. Adsorption strips are fixedly arranged on the side walls of the adsorption plates. One side of the adsorption strip away from the material receiving hopper is open. The adsorption strip and the open side are slidably attached to the inner wall of the wall-climbing belt. An adsorption air pump is fixedly arranged on the side wall of the wall-climbing vehicle. The air extraction end of the adsorption air pump is communicated with the inside of the adsorption strip, and the air exhaust end of the adsorption air pump faces the outside of the material receiving hopper.

[0011] As a further optimization of this solution, adsorption holes are arranged in an array along the winding direction of the wall-climbing belt on the wall-climbing belt. The adsorption holes are correspondingly arranged with the adsorption strips. The adsorption holes moving to the adsorption strip area are communicated with the adsorption air pump. Anti-slip teeth are arranged along the winding direction of the wall-climbing belt in the middle of the inner wall of the wall-climbing belt. Anti-slip grooves are annularly arranged on the circumferential outer wall of the wall-climbing driving wheel. When the wall-climbing driving wheel runs, the anti-slip teeth cooperate with the anti-slip grooves, and the anti-slip teeth are stuck into the anti-slip grooves to prevent sliding between the wall-climbing belt and the wall-climbing driving wheel.

[0012] The beneficial effects obtained by the present invention are as follows: (1) The present invention creatively designs a cutting manipulator. By using a clever two-way hydraulic circuit design, the two groups of adaptive clamping members can perform asymmetric movements. One group of adaptive clamping members will automatically stop running after contacting the water-stop screw steel bar, and the other group of adaptive clamping members can continue to run to the water-stop screw steel bar, so as to reliably and adaptively clamp the water-stop screw steel bar in any area covered by the cross beam. This clamping method does not require centering of the water-stop screw steel bar, which also adapts to the position error of the water-stop screw steel bar at the construction site and has higher applicability. At the same time, the automatic cutting of the water-stop screw steel bar is realized by using the hydraulic change generated by the clamping action, which significantly improves the cutting efficiency and enhances the safety. (2) The cutting manipulator and the wall-climbing vehicle are automatically controlled through a pressure sensor, a squeezing switch and a reversing switch. After the cutting is completed, the cutting manipulator can automatically place the water-stop screw steel bar into the material receiving hopper. The automatic control method of adaptive clamping, automatic cutting, automatic recovery and automatic release ensures safe and efficient cutting and avoids the risk of steel bar falling. (3) During the upward movement of the wall-climbing vehicle along the vertical surface of the dam body, the adsorption strip will move relative to the wall-climbing belt. The adsorption holes entering the adsorption strip area adsorb the vertical surface of the dam body, and the adsorption holes leaving the adsorption strip area no longer generate adsorption effect. Therefore, the wall-climbing vehicle realizes the effect of dynamic adsorption and traveling by means of the dynamic correspondence between the adsorption holes and the adsorption strip. At the same time, the gas discharged by the adsorption air pump faces the outside of the vertical surface of the dam body, and can also generate a pressing effect on the wall-climbing vehicle to further prevent the wall-climbing vehicle from falling off. (4) A simple and clever hydraulic pipeline is arranged between the adaptive clamping member and the power box. The automatic clamping of the water-stop screw steel bar is realized through a hydraulic driving method, and the adaptive clamping member can adapt to the position of the water-stop screw steel bar. (5) The cutting manipulator utilizes the extrusion effect between the wall-climbing vehicle and the water-stop screw steel bars during movement to achieve automatic clamping and cutting of the water-stop screw steel bars, eliminating the need for complex recognition systems and control devices, and significantly reducing the equipment cost.

A rack 214 is arranged on the upper wall of the cross beam 21. Pressure sensors 215 are arranged in an array on the upper wall of the cross beam 21. The pressure sensors 215 are evenly distributed below the lower wall of the touch beam 213. The adaptive clamping member 22 includes a clamping block 221, an impeller cavity 222 and a clamping gear 223. The clamping block 221 is horizontally slidably clamped on the side wall of the cross beam 21. A guide plate 224 is fixedly arranged on the upper wall of the clamping block 221. Rubber clamping strips 225 are respectively fixedly arranged on the opposite side walls of the clamping blocks 221 in the two adaptive clamping members 22. The impeller cavity 222 is fixedly arranged on the side wall of the clamping block 221. A two-way impeller 226 is rotatably arranged on the inner wall of the impeller cavity 222. The clamping gear 223 is rotatably arranged on the outer wall of the impeller cavity 222. The clamping gear 223 is coaxially and fixedly connected to the two-way impeller 226. The clamping gear 223 is meshed with the rack 214. The two-way impeller 226 realizes transmission with the cross beam 21 through the meshing of the clamping gear 223 and the rack 214. The two-way impeller 226 drives the clamping gear 223 to rotate, so that the clamping block 221 slides along the side wall of the cross beam 21. A first liquid flow pipe 227 and a second liquid flow pipe 228 penetrate through the circumferential outer wall of the impeller cavity 222. The first liquid flow pipe 227 and the second liquid flow pipe 228 penetrate through the clamping block 221.

[0018] A two-way gear pump 241 is fixedly arranged on the inner wall of the power box 24. The two-way gear pump 241 and the wall-climbing power wheel 12 are respectively electrically connected to the pressure sensor 215. When the pressure sensor 215 is subjected to extrusion, the two-way gear pump 241 starts to operate, and the wall-climbing power wheel 12 stops operating. A hose 242 is connected between the bottom wall of the power box 24 and the bottom wall of the clamping block 221. The first liquid flow pipe 227 and the second liquid flow pipe 228 are laid along the inner wall of the hose 242. The ends of the first liquid flow pipes 227 in the two adaptive clamping members 22 away from the impeller cavity 222 both penetrate through the bottom wall of the power box 24 and are communicated with one end of the two-way gear pump 241. The ends of the second liquid flow pipes 228 in the two adaptive clamping members 22 away from the impeller cavity 222 both penetrate through the bottom wall of the power box 24 and are communicated with the other end of the two-way gear pump 241.

[0019] The cutting assembly 23 includes a telescopic rod 231, a pushing plate 232, and a cutting motor 233. The base portion of the telescopic rod 231 is fixedly provided on the side wall of the clamping block 221.

A tension spring is provided inside the telescopic rod 231, and both ends of the tension spring are respectively connected to the base portion and the push rod portion of the telescopic rod 231. The setting of the tension spring makes it necessary for a relatively large hydraulic force to be applied to realize the elongation process of the telescopic rod 231. The cutting motor 233 is horizontally slidably provided on the upper wall of the clamping block 221. A pressure pipe 234 is communicated between the end of the base portion of the telescopic rod 231 and the middle of the first liquid flow pipe 227. The pushing plate 232 is inclinedly driven with the cutting motor 233. Specifically, an inclined groove 235 is provided on the pushing plate 232, and a dial button 236 is fixedly provided on the side wall of the cutting motor 233. The dial button 236 is movably embedded in the inclined groove 235. A cutting blade 237 is connected to the output shaft of the cutting motor 233. An extrusion switch 229 is provided on the clamping block 221. The extrusion switch 229 is located on the movement path of the cutting motor 233. The extrusion switch 229 is electrically connected to the steering motor 11. When the telescopic rod 231 is elongated under the action of hydraulic push, it can push the pushing plate 232 to move. The guiding action of the inclined groove 235 causes the dial button 236 to drive the cutting motor 233 to slide, so that the cutting blade 237 moves to the position of the water-stop screw steel bar and performs cutting. When the cutting motor 233 presses the extrusion switch 229, the cutting blade 237 has completed the cutting of the water-stop screw steel bar, and the steering motor 11 is powered on and runs.

[0020] The communication space of the impeller chamber 222, the first liquid flow pipe 227, the second liquid flow pipe 228, the bi-directional gear pump 241, and the pressure pipe 234 is filled with hydraulic oil.

[0021] Adsorption plates 15 are symmetrically and fixedly provided on both side walls of the wall-climbing vehicle 1. Adsorption strips 151 are fixedly provided on the side walls of the adsorption plates 15. The side of the adsorption strip 151 away from the material receiving hopper 14 is open. The side of the adsorption strip 151 away from the material receiving hopper 14 is slidably fitted with the inner wall of the wall-climbing belt 13. An adsorption air pump 16 is fixedly provided on the side wall of the wall-climbing vehicle 1. The air suction end of the adsorption air pump 16 is communicated with the inside of the adsorption strip 151, and the air exhaust end of the adsorption air pump 16 faces the outside of the material receiving hopper 14.

[0022] The inner wall of the wall-climbing belt 13 is provided with a raised belt 131, the adsorption strip 151 is arranged corresponding to the raised belt 131, adsorption holes 132 are arranged in an array along the winding direction of the wall-climbing belt 13 on the wall-climbing belt 13, the adsorption holes 132 are located in the raised belt 131, the adsorption holes 132 are arranged corresponding to the adsorption strip 151, the adsorption holes 132 moving to the position of the adsorption strip 151 communicate with the adsorption air pump 16, anti-slip teeth 133 are arranged along the winding direction of the wall-climbing belt 13 in the middle of the inner wall of the wall-climbing belt 13, anti-slip grooves 121 are arranged in an annular array on the circumferential outer wall of the wall-climbing driving wheel 12, when the wall-climbing driving wheel 12 runs, the anti-slip teeth 133 cooperate with the anti-slip grooves 121, and the anti-slip teeth 133 are stuck into the anti-slip grooves 121 to prevent sliding between the wall-climbing belt 13 and the wall-climbing driving wheel 12. A lubricant is applied between the raised belt 131 and the adsorption strip 151, which can not only ensure the sealing effect of the contact surface between the raised belt 131 and the adsorption strip 151, but also reduce the movement resistance of the wall-climbing belt 13 relative to the adsorption strip 151.

[0023] A reversing switch 17 is arranged at the upper end of the wall-climbing vehicle 1, the reversing switch 17 is located at the side of the steering shaft 211 of the cross beam 21, the two-way gear pump 241 and the steering motor 11 are respectively electrically connected to the reversing switch 17. When the extrusion switch 229 controls the steering motor 11 to run and the cutting manipulator 2 is turned as a whole, the cutting manipulator 2 will bring the cut water-stop screw steel bars into the material receiving hopper 14. When the cross beam 21 touches the reversing switch 17, the steering motor 11 runs in the reverse direction to reset, and the two-way gear pump 241 runs in the reverse direction to release the cut water-stop screw steel bars.

[0024] The specific use process of this embodiment is as follows: There are a large number of exposed water-stop screw steel bars on the vertical surface of the dam body. First, the wall-climbing vehicle 1 in this solution is closely attached to the vertical surface at the bottom of the dam body to prepare for cutting operations. In the initial state, the relative positional relationship between the cutting manipulator 2 and the wall-climbing vehicle 1 is as Figures 1 - 3 shown, that is, in the initial state, the cutting manipulator 2 also approaches the vertical surface of the dam body, the two adaptive clamping members 22 are far away from each other, and the state of the cutting assembly 23 is as Figure 5 and Figure 10As shown, the telescopic rod 231 is in a contracted state, and the adsorption air pump 16 operates to extract the gas in the adsorption strip 151, creating a negative pressure in the adsorption strip 151. The adsorption holes 132 at the adsorption strip 151 are in communication with the adsorption air pump 16. Therefore, the adsorption strip 151 can perform negative pressure adsorption on the dam facade through these adsorption holes 132, causing the wall-climbing vehicle 1 to adsorb onto the dam facade. The wall-climbing driving wheel 12 operates to drive the wall-climbing vehicle 1 to move upward along the dam facade. During this process, the adsorption strip 151 will move relative to the wall-climbing belt 13. The adsorption holes 132 entering the adsorption strip 151 area adsorb the dam facade, and the adsorption holes 132 leaving the adsorption strip 151 area no longer produce adsorption effect. Therefore, the wall-climbing vehicle 1 realizes the effect of dynamic adsorption and traveling by means of the dynamic correspondence between the adsorption holes 132 and the adsorption strip 151. At the same time, the gas discharged by the adsorption air pump 16 is directed towards the outside of the dam facade, and can also generate a pressing effect on the wall-climbing vehicle 1 to further prevent the wall-climbing vehicle 1 from falling off.

[0025] The wall-climbing vehicle 1 drives the cutting manipulator 2 to move upward. When encountering the exposed water-stop screw reinforcement, since the cutting manipulator 2 moves upward, the water-stop screw reinforcement will press and touch the beam 213 (if the water-stop screw reinforcement does not directly align with and touch the beam 213 but aligns with the guide plate 224, the inclined guiding effect of the guide plate 224 can cause the corresponding self-adaptive clamping member 22 of the guide plate 224 to slide, and make the water-stop screw reinforcement enter between the two self-adaptive clamping members 22 and press on the beam 213). The touch beam 213 will squeeze the pressure sensor 215, and the wall-climbing driving wheel 12 stops operating, and the wall-climbing vehicle 1 stabilizes on the dam facade. The double gear pump 241 starts to operate. Please refer to Figure 9 During this process, the pumping direction of the double gear pump 241 is downward, that is, in the power box 24, the hydraulic oil will enter the liquid flow pipe 227 from the liquid flow pipe 228, and then the hydraulic oil will reach the impeller cavity 222 along the liquid flow pipe 227 and enter the liquid flow pipe 228 again. This process will drive the double impeller 226 to rotate to Figure 7 For example, at this time, the double impeller 226 in the left self-adaptive clamping member 22 rotates clockwise, and the double impeller 226 in the right self-adaptive clamping member 22 rotates counterclockwise, thereby driving the clamping gear 223 to rotate, causing the two clamping blocks 221 to slide along the side wall of the cross beam 21 and approach each other. When one of the clamping blocks 221 touches the side wall of the water-stop screw reinforcement, this clamping block 221 is blocked and cannot continue to move, then the double impeller 226 corresponding to this clamping block 221 cannot continue to rotate. At this time, the hydraulic oil can only flow in the other group of liquid flow pipes 227 and 228, so that the double impeller 226 corresponding to the other clamping block 221 continues to rotate, and the other clamping block 221 approaches the other side wall of the water-stop screw reinforcement.

[0026] The above clamping method has significant advantages. By means of a clever hydraulic circuit design, the two groups of adaptive clamping members 22 can perform asymmetric motion. After one group of adaptive clamping members 22 comes into contact with the water-stop screw steel bar, it will automatically stop running, and the other group of adaptive clamping members 22 can continue to run to the position of the water-stop screw steel bar, so that the water-stop screw steel bar in any area covered by the cross beam 21 can be reliably clamped. This clamping method does not require centering of the water-stop screw steel bar, which also adapts to the position error of the water-stop screw steel bar at the construction site and has higher applicability.

[0027] When the rubber clamping strips 225 on the two clamping blocks 221 are both in close contact with the water-stop screw steel bar, the clamping effect is achieved. The two bidirectional impellers 226 cannot rotate, and the passage of the hydraulic oil is blocked, so the hydraulic pressure in the first liquid flow pipe 227 will increase significantly. The internal hydraulic pressure of the pressure pipe 234 increases, and the hydraulic oil enters the telescopic rod 231 through the pressure pipe 234, causing the pushing piece 232 to move. The guiding action of the inclined groove 235 makes the dial button 236 drive the cutting motor 233 to slide, so that the cutting blade 237 moves to the position of the water-stop screw steel bar and cuts the water-stop screw steel bar. When the cutting motor 233 presses against the extrusion switch 229, the cutting blade 237 has completed the cutting of the steel bar. The steering motor 11 is energized and runs. The steering motor 11 drives the steering gear 111 to rotate, so that the driven gear 212 drives the steering shaft 211 to rotate, and thus the entire cross beam 21 rotates. The water-stop screw steel bar clamped by the adaptive clamping member 22 gradually rotates into the material receiving hopper 14. When the cross beam 21 touches the commutation switch 17, the steering motor 11 runs in the reverse direction to drive the cross beam 21 to reset. The bidirectional gear pump 241 runs in the reverse direction, and the bidirectional impellers 226 run in the reverse direction. The two groups of adaptive clamping members 22 move away from each other, and the water-stop screw steel bar falls off and drops into the material receiving hopper 14. The hydraulic pressure in the first liquid flow pipe 227 decreases, the cutting assembly 23 resets, the extrusion force of the pressure sensor 215 returns to the initial state, and the wall-climbing power wheel 12 continues to run, driving the wall-climbing vehicle 1 to move upward to perform adaptive clamping, cutting and collection on the next water-stop screw steel bar.

[0028] Embodiment 2: This embodiment is based on Embodiment 1. In this embodiment, in order to ensure the stability of the wall-climbing vehicle 1 during the wall-climbing process, rubber suction cups are arranged in an array on the outer wall of the wall-climbing belt 13. The rubber suction cups are in one-to-one correspondence and communication with the suction holes 132. The rubber suction cups expand the suction area of the suction holes 132 and improve the suction reliability.

[0029] Embodiment 3: This embodiment is based on Embodiment 1. In this embodiment, in order to ensure the stability of the wall-climbing vehicle 1 during the wall-climbing process, ear plates are symmetrically arranged on both side walls of the material receiving hopper 14. Steel wires are passed through the ear plates. The upper ends of the steel wires are placed on the upper part of the dam body of the dam, the upper ends of the steel wires are locked, and the steel wires are dragged upward by a winch to provide safety insurance for the wall-climbing vehicle 1 to prevent the wall-climbing vehicle 1 from falling off.
