Description

Technical Field

[0001] The utility model mainly relates to the technical field of production facilities and equipment of water plants, in particular to a mud discharge vehicle for a sedimentation tank of a water plant. Background Art

[0002] At present, the sludge discharge vehicle of the water plant moves at a fixed speed and regularly cleans the sludge at the bottom of the sedimentation tank.

[0003] When the existing sludge discharge crane is cleaning the sludge, it is unable to understand the sludge accumulation situation, resulting in load fluctuations and unbalanced forces on the motor and rollers due to different resistances when the crane is moving, which leads to a high failure rate of the crane. In severe cases, there may be a risk of roller derailment due to uneven forces on both sides, which will bring hidden dangers to the production of the water plant and the safety of personnel. Utility Model Content

[0004] The technical solution of the utility model aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. It mainly provides a sludge discharge vehicle for a water plant sedimentation tank, which is used to solve the technical problem proposed in the above background technology that when the sludge discharge vehicle is cleaning the sludge, the vehicle will deviate due to uneven force on both sides, causing the roller to derail.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A sludge discharge crane for a sedimentation tank in a water plant comprises a crane body and a slide rail body, wherein a roller is arranged below the crane body, and the roller is arranged above the slide rail body, an adjustment component for increasing the friction force of the roller movement is arranged below the slide rail body, and a control mechanism for driving the adjustment component is arranged above the crane body.

[0007] Preferably, the control mechanism includes a control box and a sensor, the control box is arranged above the vehicle body, a torque detector is arranged below the control box, and the sensor is arranged on one side of the vehicle body.

[0008] Preferably, the roller is rotatably connected to a bracket, the bracket is fixedly mounted on both sides below the vehicle body, and the roller moves forward and backward along the top of the slide rail body.

[0009] Preferably, motors are fixedly mounted below both sides of the vehicle body, a rotating shaft is fixedly mounted on the motor output shaft, and one end of the rotating shaft is fixedly connected to the roller rotating shaft.

[0010] Preferably, the adjustment assembly comprises a hydraulic cylinder, the hydraulic cylinder is fixedly mounted above the traveling body, a lifting block is fixedly mounted on the lower end of the telescopic rod of the hydraulic cylinder, and the lifting block is slidably connected to the roller bracket.

[0011] Preferably, linkage rods are rotatably connected inside both sides of the lifting block, and the linkage rods are rotatably connected to the moving block at one end away from the lifting block. A limiting groove is opened under the driving body, and the moving block is slidably connected inside the limiting groove. A friction plate is fixedly installed under the moving block.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: the torque detector inside the control box collects the resistance received by the sludge cleaning on both sides of the vehicle body, and then feeds it back to the control box. The control box increases the friction force on the side where the sludge cleaning force is less through the control adjustment component, thereby achieving the consistency of the force on the rollers of the vehicle body on both sides, thereby maintaining the same moving speed and forward distance on both sides of the vehicle body to prevent derailment.

[0013] The sensor detects the horizontal line of the vehicle body. When the deviation on both sides of the vehicle body is too large, causing a large offset of the entire vehicle body, the sensor controls the motors on both sides to stop working through the control box. At the same time, the adjustment component locks the slide rail to stop the vehicle body from moving at the fastest speed to prevent the vehicle body from continuing to move and offset more and more, leading to derailment and overturning.

[0024] Please refer to the attached Figure 1-Figure 5 A sludge discharge crane for a sedimentation tank in a water plant comprises a crane body 1 and a slide rail body 2. A roller 3 is arranged below the crane body 1, and the roller 3 is arranged above the slide rail body 2. An adjustment component for increasing the friction force of the roller 3 is arranged below the slide rail body 2, and a control mechanism for driving the adjustment component is arranged above the crane body 1.

[0025] The specific operation process of the utility model is as follows: the roller 3 body drives the traveling body 1 to move forward and backward along the slide rail body 2, and the traveling body 1 cleans the sludge in the water pool by moving forward and backward. Since the amount of sludge in the water pool is uncertain, the forces on both sides of the traveling body 1 are different, which will cause the forward speeds of the rollers 3 on both sides to be different. The side with less force controls the adjustment component through the control mechanism to increase the friction force, so as to keep the forces on both sides of the traveling body 1 consistent, and make the rollers 3 on both sides of the traveling body 1 move at the same rate.

[0026] Reference Figure 1-Figure 5 The control mechanism includes a control box 11 and a sensor 12. The control box 11 is arranged above the driving body 1. A torque detector is arranged below the control box 11. The sensor 12 is arranged on one side of the driving body 1.

[0027] The control box 11 is arranged on both sides above the driving body 1. The control box 11 is used to drive the motor 4 and the hydraulic cylinder 6. The torque detector is used to detect the resistance encountered by cleaning sludge on both sides below the driving body 1. If the driving body 1 is subject to greater resistance, the control box 11 will control the adjustment component on the other side to increase the friction, so as to keep the force on both sides relatively consistent. The sensor 12 is used to monitor the horizontal plane of the driving body 1. When the sensor 12 detects that the driving body 1 is deviated too much, the sensor 12 controls the driving body 1 to stop moving as soon as possible through the control box 11.

[0028] Please refer to Figure 1-Figure 5 The roller 3 is rotatably connected to the bracket, and the bracket is fixedly installed on both sides below the traveling body 1. The roller 3 moves forward and backward along the top of the slide rail body 2. Motors 4 are fixedly installed below both sides of the traveling body 1. A rotating shaft 5 is fixedly installed on the output shaft of the motor 4, and one end of the rotating shaft 5 is fixedly connected to the rotating shaft of the roller 3.

[0029] Start the motor 4, the motor 4 drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the roller 3 to rotate, the roller 3 moves back and forth along the slide rail body 2, the roller 3 drives the traveling body 1 to move back and forth, and the traveling body 1 cleans the sludge inside the pool by moving back and forth.

[0030] Please refer to Figure 1-Figure 5 The adjustment component includes a hydraulic cylinder 6, which is fixedly installed above the driving body 1. A lifting block 7 is fixedly installed at the lower end of the telescopic rod of the hydraulic cylinder 6. The lifting block 7 is slidably connected to the roller 3 bracket. Linkage rods 8 are rotatably connected inside the two sides of the lifting block 7. The end of the linkage rod 8 away from the lifting block 7 is rotatably connected to the moving block 9. A limiting groove 13 is opened at the bottom of the driving body 1. The moving block 9 is slidably connected inside the limiting groove 13. A friction plate 10 is fixedly installed below the moving block 9.

[0031] Start the hydraulic cylinder 6, which drives the lifting block 7 to rise through the telescopic rod. The lifting block 7 rises and pulls the two linkage rods 8. The two linkage rods 8 rise and rotate, and the two linkage rods 8 reduce the angle between the lifting block 7 and the lifting block 7. The other ends of the two linkage rods 8 pull the two moving blocks 9. Since the two moving blocks 9 are slidably connected with the limiting groove 13 opened below the driving body 1, the two moving blocks 9 can only move left and right in a straight line. The two linkage rods 8 pull the two moving blocks 9 to move inward synchronously, and the two moving blocks 9 drive the two friction plates 10 below to move inward. The friction plate 10 moves inward and fits on both sides of the slide rail body 2. The friction plate 10 increases the friction force of the roller 3. In this way, when the sludge resistance on one side of the traveling body 1 is greater than that on the other side, the friction provided by the friction plate 10 can make the forces on both sides of the traveling body 1 consistent. In this way, the moving speeds of the rollers 3 on both sides will be consistent, preventing the traveling body 1 from deviating. When the lifting block 7 rises to the highest point, the friction plates 10 on both sides clamp the slide rail body 2, which is in a locked state. In this way, the traveling body 1 can be stopped from a moving state as quickly as possible.

[0032] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
