Description

Technical Field

[0001] The present application relates to the technical field of aluminum electrolytic cell equipment, and in particular to a device for measuring the height of an electrolytic aluminum anode. Background Art

[0002] The production of electrolytic aluminum is to obtain aluminum through the electrolysis of aluminum oxide powder. It uses carbon as anode, aluminum oxide powder as solute, and the carbon block at the bottom of the electrolytic cell as cathode. Strong direct current is passed to complete electrolysis. In the production process of aluminum electrolysis, the anode carbon block will be continuously consumed as the electrolysis proceeds. When it is consumed to a certain extent, it needs to be replaced. The anode that is consumed and needs to be replaced is called the old anode, also known as the residual anode, and the replaced anode is called the new anode; according to the production process requirements of aluminum electrolysis, the bottom palm plane (bottom surface) of the new anode should be on the same horizontal plane as the bottom palm plane (bottom surface) of the residual anode in the electrolytic cell. The greater the deviation between the new anode and other old anodes, the more likely it is to produce abnormal effects, thereby deteriorating the quality of the produced aluminum liquid. This will not only reduce production output, but also cause energy waste. Therefore, when replacing the anode, it is necessary to measure the height of the new and old anodes for easy positioning.

[0003] At present, an anode height measuring device for measuring the height of old and new anodes has two telescopic rods, one of which has a clamping claw for clamping the tops of the new and old anodes in turn and lifting them to the same height, and the bottom of the other telescopic rod is provided with a laser sensor, which can measure the height difference between the bottom palm planes of the new and old anodes. According to the height difference, the distance that the bottom palm plane of the new anode needs to move from the outside to the horizontal plane where the bottom palm plane of the residual anode in the electrolytic cell is located can be calculated; when the anode is replaced, the two telescopic rods will move between the electrolytic cell containing the old anode and the anode prebaking furnace containing the new anode. Before moving to above the electrolytic cell and above the anode prebaking furnace, the two telescopic rods do not need to extend. When the telescopic rod with the laser sensor is extended downward by mistake, the laser sensor will collide with other objects and be damaged, affecting the use of the anode height measuring device.

[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] At present, an anode height measuring device for measuring the height of old and new anodes has two telescopic rods, one of which has a clamping claw for clamping the tops of the new and old anodes in turn and lifting them to the same height, and the bottom of the other telescopic rod is provided with a laser sensor, which can measure the height difference between the bottom palm planes of the new and old anodes. According to the height difference, the distance that the bottom palm plane of the new anode needs to move from the outside to the horizontal plane where the bottom palm plane of the residual anode in the electrolytic cell is located can be calculated; when the anode is replaced, the two telescopic rods will move between the electrolytic cell containing the old anode and the anode prebaking furnace containing the new anode. Before moving to above the electrolytic cell and above the anode prebaking furnace, the two telescopic rods do not need to extend. When the telescopic rod with the laser sensor is extended downward by mistake, the laser sensor will collide with other objects and be damaged, affecting the use of the anode height measuring device.

[0031] In view of this, the present application proposes a device for measuring the height of an electrolytic aluminum anode. Figures 1 to 9 This is a schematic diagram of the structure of the electrolytic aluminum anode height measuring device of the present application.

[0032] See also Figures 1 to 6 The present application proposes an electrolytic aluminum anode height measuring device 100, which includes a crane base 1, a tool trolley 2, a laser sensor 3, a second telescopic rod 4 and an anti-collision structure 5. The tool trolley 2 is movably arranged on the crane base 1, and the tool trolley 2 is provided with a first telescopic rod 21, and the first telescopic rod 21 is provided with a clamping claw 211. One end of the second telescopic rod 4 is connected to the tool trolley 2, and the other end of the second telescopic rod 4 is provided with an avoidance groove 41. The collision structure 5 includes a resisting body 51, and the resisting body 51 has a connecting end 512 and a resisting end 513 that are relatively arranged, and the connecting end 512 is connected to the front surface 31 of the laser sensor 3, and the front surface 31 and the connecting end 512 are close to the bottom of the avoidance groove 41, and the resisting body 51 is movably connected to the avoidance groove 41 and can move between the anti-collision position and the resisting position. In the anti-collision position, the blocking body 51 and the laser sensor 3 are located inside the avoidance groove 41; in the blocking position, the laser sensor 3 and the blocking end 513 are located outside the avoidance groove 41, and the blocking end 513 is away from the laser sensor 3 in the length direction of the second telescopic rod 4. In the anti-collision position, the blocking end 513 can also be arranged away from the laser sensor 3 in the length direction of the second telescopic rod 4; in the initial state, the blocking body 51 can be in the blocking position.

[0033] In the embodiment provided in the present application, the tool vehicle 2 drives the first telescopic rod 21 and the second telescopic rod 4 to move along the overhead traveling vehicle base 1 between the electrolytic cell and the anode pre-baking furnace below the overhead traveling vehicle base 1. When the first telescopic rod 21 has not reached the top of the electrolytic cell or the anode pre-baking furnace, the first telescopic rod 21 and the second telescopic rod 4 are both in a non-working range, that is, the first telescopic rod 21 and the second telescopic rod 4 are both in an initial non-extended state; when the first telescopic rod 21 reaches the top of the electrolytic cell or the anode pre-baking furnace, the first telescopic rod 21 and the second telescopic rod 4 are both in a working range. In the non-working range, the first telescopic rod 21 and the second telescopic rod 4 do not need to be extended; in the working range, the first telescopic rod 21 and the second telescopic rod 4 must perform telescopic actions. In the non-working range, a large obstacle may appear below the overhead crane base 1, and the size of the obstacle may be larger than the size of the slot of the avoidance groove 41. Since in the blocking position, the blocking end 513 of the blocking body 51 and the laser sensor 3 are both outside the avoidance groove 41, that is, the laser sensor 3 is below the bottom surface of the corresponding second telescopic rod 4, and the blocking end 513 is away from the laser sensor 3 in the length direction of the second telescopic rod 4 and closer to the larger obstacle below, when the tool vehicle 2 moves in the non-working range, the second telescopic rod 4 is moved toward the larger obstacle due to misoperation of the staff. After extension, the blocking end 513 of the blocking body 51 will first touch the larger obstacle. Since the blocking body 51 is movably connected to the avoidance groove 41, as the second telescopic rod 4 touches the larger obstacle and continues to extend, the larger obstacle will be subjected to the downward thrust from the blocking end 513, and the blocking end 513 will be subjected to the reaction force of the larger obstacle and drive the laser sensor 3 to move upward to the anti-collision position; in the anti-collision position, that is, the blocking body 51 and the laser sensor 3 are both inside the avoidance groove 41, and only the slot end of the avoidance groove 41 is closer to the larger obstacle. When the tool cart 2 moves at a faster speed, the obstacle only collides with the resisting body 51, and the slot end of the avoidance groove 41 will move away from the obstacle along with the tool cart 2 when it does not touch the obstacle; when the tool cart 2 moves at a slower speed, the obstacle will successively collide with the resisting body 51 and the slot end of the avoidance groove 41, and the slot end of the avoidance groove 41 will also move away from the obstacle along with the tool cart 2. During this moving process, the laser sensor 3 never touches the obstacle, which can prevent the laser sensor 3 from being damaged by collision.Among them, the connecting end 512 is connected to the front surface 31 of the laser sensor 3. When the blocking body 51 is hit by an obstacle and moves toward the bottom of the avoidance groove 41, the connecting end 512 of the blocking body 51 will pull the laser sensor 3 to move, which can prevent the laser sensor 3 from being pushed by the blocking body 51 and reduce the possibility of the laser sensor 3 being hit by the blocking body 51; after the blocking body 51 and the slot end of the avoidance groove 41 are separated from the obstacle, the blocking body 51 and the laser sensor 3 will move downward to the blocking position due to their own gravity. At the blocking position, the laser sensor 3 is outside the avoidance groove 41, so that the laser sensor 3 is not completely blocked and can work normally.

[0034] It should be noted that the first telescopic rod 21 and the second telescopic rod 4 can be electric telescopic rods; when the tool cart 2 drives the first telescopic rod 21 to the top of the electrolytic cell, the first telescopic rod 21 is first extended into the electrolytic cell, the top of the residual anode is clamped by the clamping claw 211, and the first telescopic rod 21 is retracted to lift the residual anode to a certain height, and then the second telescopic rod 4 is in the maximum extension state, and then the second telescopic rod 4 is retracted upward. During the upward retraction process, the laser sensor 3 is always detecting, and the emission direction of the laser sensor 3 is horizontally toward the first telescopic rod 21. When the anode bottom of the residual anode is detected, the retraction action of the second telescopic rod 4 is stopped, and the final extension of the second telescopic rod 4 at this time is recorded. When the tool vehicle 2 drives the first telescopic rod 21 to move above the anode pre-baking furnace, the first telescopic rod 21 extends into the anode pre-baking furnace, clamps the top of the new anode through the clamping claw 211, and retracts the first telescopic rod 21, so that the top of the new anode is lifted to the same height as the top of the residual anode, and then the second telescopic rod 4 is in the maximum extension state, and then the second telescopic rod 4 is retracted upward. During the upward retraction process, the laser sensor 3 is always detecting, and the emission direction of the laser sensor 3 is horizontally toward the first telescopic rod 21. When the anode bottom of the new anode is detected, the retraction action of the second telescopic rod 4 is stopped, and the final extension of the second telescopic rod 4 at this time is recorded. Finally, the difference between the two final extensions of the second telescopic rod 4 is calculated, which is the height difference between the anode bottom of the residual anode and the anode bottom of the new anode, that is, when the new anode is placed in the electrolytic cell and the anode bottom of the new anode is at the same horizontal plane as the anode bottoms of other residual anodes in the electrolytic cell, the height difference between the top of the new anode and the top of the residual anode. During the anode replacement process, a residual anode in the electrolytic cell is first taken out, and then a new anode is gradually moved down from the outside toward the electrolytic cell. When the top of the new anode moves down to the same height difference as the top of other residual anodes in the electrolytic cell and the difference between the two final extension amounts of the second telescopic rod 4, the movement of the new anode is stopped, so that the anode bottom of the new anode and the anode bottom of other residual anodes in the electrolytic cell are at the same horizontal plane, thereby completing the anode replacement work. After the anode replacement is completed, the top of the new anode is higher than the tops of other residual anodes; the anode bottom of the new residual anode is the bottom surface of the new anode and the residual anode.

[0035] When the size of the obstacle under the overhead crane base 1 is small, the bottom surface of the laser sensor 3 will be exposed to the smaller obstacle, that is, the smaller obstacle may be located below the bottom surface of the corresponding laser sensor 3. In order to prevent the smaller obstacle from approaching the center of the slot of the avoidance slot 41 and avoiding the blocking body 51 and colliding with the laser sensor 3, in an embodiment of the present application, the anti-collision structure 5 also includes an anti-collision body 511 fixedly connected to the blocking end 513 and shielding the laser sensor 3. The anti-collision body 511 extends in an arc shape and protrudes toward the bottom of the slot away from the avoidance slot 41. By providing the anti-collision body 511, when the second telescopic rod 4 is extended toward the obstacle in the non-working range, since the anti-collision body 511 is closer to the obstacle and can block the bottom surface of the laser sensor 3, the obstacle will first contact and collide with the anti-collision body 511, and then the resisting body 51 will pull the laser sensor 3 into the avoidance groove 41, and then the obstacle will touch the notch end of the avoidance groove 41. During the extension of the second telescopic rod 4, the laser sensor 3 has never contacted a smaller obstacle, thereby avoiding damage to the laser sensor 3 due to collision. Among them, the arc-shaped anti-collision body 511 can not only withstand a large impact force, but also has a certain elasticity, which can buffer the collision of the obstacle and reduce the impact on itself and the resisting body 51 when colliding with the obstacle.

[0036] In order to further reduce the impact of the collision of the obstacle on the laser sensor 3, in the embodiment of the present application, the anti-collision structure 5 also includes an elastic member 53, one end of the elastic member 53 is connected to the bottom wall of the avoidance groove 41, and the other end is connected to the laser sensor 3. The other end of the elastic member 53 can be connected to the front surface of the laser sensor 3, and can also be connected to the abutting end 513 of the abutting body 51. After the abutting body 51 collides with the obstacle, it will drive the laser sensor 3 to move toward the bottom of the avoidance groove 41. If the collision force is large, the movement speed of the abutting body 51 and the laser sensor 3 will become faster. By setting the elastic member 53, a buffer can be formed for the laser sensor 3 and the abutting body 51, and the movement speed of the laser sensor 3 and the abutting body 51 can be slowed down, thereby reducing the impact of the collision on the laser sensor 3. If the abutting body 51 and the laser sensor 3 enter the avoidance groove 41 and contact the bottom of the avoidance groove 41, the setting of the elastic member 53 will reduce the collision force between the laser sensor 3 and the bottom wall of the avoidance groove 41. When an obstacle collides with the notch end of the avoidance groove 41, the second telescopic rod 4 will generate a certain vibration, and the elastic member 53 can reduce the impact of the vibration on the laser sensor 3. When the second telescopic rod 4 moves away from the obstacle along with the tool vehicle 2, the elastic member 53 will be converted from a compressed state to an extended state, and the elastic force of the elastic member 53, the gravity of the laser sensor 3 and the gravity of the resisting body 51 will make the laser sensor 3 more quickly reach the outside of the avoidance groove 41 from the inside of the avoidance groove 41, so that the laser sensor 3 can work smoothly. The number of elastic members 53 can be two, and the two elastic members 53 can be connected to the connection end 512 of the resisting body 51 and the laser sensor 3 respectively.

[0037] When the tool vehicle 2 is moving in the non-working range, in order to reduce the impact of the collision on the second telescopic rod 4 when an obstacle on the crane base 1 collides with the outer peripheral wall of the extended second telescopic rod 4, or when an obstacle with a height close to the height of the middle part of the second telescopic rod 4 in the maximum extension state appears below the crane base 1, in order to reduce the impact of the collision on the second telescopic rod 4 when the obstacle with a higher height collides with the outer peripheral wall of the extended second telescopic rod 4, in the embodiment of the present application, an anti-collision pad is provided on the outer peripheral wall of the second telescopic rod 4, and the material of the anti-collision pad is rubber material. By wrapping the rubber anti-collision pad on the outer peripheral wall of the second telescopic rod 4, when the outer peripheral wall of the second telescopic rod 4 is collided, the rubber anti-collision pad can produce a large deformation, prolong the time of the collision, thereby reducing the magnitude of the impact force, and can also reduce the vibration and noise caused by the collision.

[0038] In order to prevent the first telescopic rod 21 from being damaged due to collision in the non-working range, in the embodiment of the present application, the electrolytic aluminum anode height measuring device further includes a stop structure, which includes a stop body 26, an alarm, a fixing plate 11, a first button switch 261 and a rotating arm 22. The fixing plate 11 is arranged on the overhead travelling vehicle base 1, and the first button switch 261 is arranged on the surface of the stop body 26 facing the first telescopic rod 21. The first button switch 261 is electrically connected to the alarm so that the alarm can sound an alarm after the first telescopic rod 21 pushes the first button switch 261. The alarm can be a buzzer that can emit a sharp sound. The rotating arm 22 is rotatably mounted on the tool cart 2 and has a relative abutment section 222 and a stop section 221. The rotation plane of the rotating arm 22 can be a vertical plane. The stop section 221 is connected to the stop body 26. The stop body 26 has a stop position and an avoidance position, wherein the weight of the abutment section 222 is less than the weight of the stop section 221, so that the stop body 26 can switch between the stop position and the avoidance position depending on the weight difference between the abutment section 222 and the stop section 221. In the stop position, the stop body 26 can block the first telescopic rod 21 at the bottom, and the first button switch 261 abuts against the first telescopic rod 21; in the avoidance position, the fixed plate 11 abuts against the abutment section 222, so that the stop body 26 avoids the first telescopic rod 21. When in the non-working range, the first telescopic rod 21 is in the initial state, that is, the state that it has not been extended. In the stop position, the stop body 26 can be below the bottom surface of the first telescopic rod 21. Since the height of the first button switch 261 is very small, the first telescopic rod 21 will contact the stop body 26 when it is extended to a very small length, so the force of the collision between the first telescopic rod 21 and the stop body 26 will be very small, and the stop body 26 can also prevent the first telescopic rod 21 from continuing to extend; the first button switch 261 can close or disconnect the internal metal contacts when it is pressed or released, and the first button switch 261 can also return to the initial position after being released; the first button switch 261 is electrically connected to the alarm, and can make the alarm sound and stop the alarm after being pressed and released. When the first telescopic rod 21 contacts the first button switch 261 and continues to extend downward to push the first button switch 261, the alarm will sound an alarm to remind the operator to retract the first telescopic rod 21 to the initial state or stop the first telescopic rod 21 from continuing to extend.When the tool cart 2 moves toward the working range and the abutment section 222 of the rotating arm 22 contacts the fixed plate 11, as the tool cart 2 continues to move, the abutment section 222 will continue to apply a thrust to the fixed plate 11, and the fixed plate 11 will apply a reaction force to the abutment section 222, so that the rotating arm 22 rotates, thereby causing the stopper 26 and the first button to rotate and move away from the first telescopic rod 21, and expose the bottom surface of the first telescopic rod 21, stop the tool cart 2, and put the stopper 26 in an avoidance position, so that the first telescopic rod 21 can be avoided, and the first telescopic rod 21 can be extended downward into the inside of the electrolytic cell or the inside of the anode pre-baking furnace, wherein, in the avoidance position, the bottom surface of the stopper 26 is higher than the bottom surface of the first telescopic rod 21 in the initial non-extended state, and therefore is also higher than the bottom palm plane of the new and old anodes after being clamped; when the tool cart 2 moves toward the working range and the abutment section 222 of the rotating arm 22 contacts the fixed plate 11, as the tool cart 2 continues to move, the abutment section 222 will continue to apply a thrust to the fixed plate 11, and the fixed plate 11 will apply a reaction force to the abutment section 222, so that the rotating arm 22 rotates, thereby causing the stopper 26 and the first button to rotate and move away from the first telescopic rod 21, and expose the bottom surface of the first telescopic rod 21, and stop the tool cart 2, so that the stopper 26 is in an avoidance position, so that the first telescopic rod 21 can be avoided, and the first telescopic rod 21 can be extended downward into the inside of the electrolytic cell or the anode pre-baking furnace, wherein, in the avoidance position, the bottom surface of the stopper 26 is 2 drives the first telescopic rod 21 to leave the working range, and the abutting section 222 is disengaged from the abutment with the fixed plate 11, that is, it is not in contact with the fixed plate 11. Since the weight of the abutting section 222 is less than the weight of the stop section 221, at this time, the stop body 26 will move to the stop position under the action of gravity; in this way, the first telescopic rod 21 can only perform a large extension action within the working range, but cannot perform a large extension action within the non-working range; wherein, at the stop position, the first button switch 261 can abut against the first telescopic rod 21, or can be spaced a small distance from the first telescopic rod 21; it can be understood that a second stop structure as mentioned above can also be provided, so that the second telescopic rod 4 can only perform a large extension action within the working range, but cannot perform a large extension action within the non-working range.

[0039] In order to stop the first telescopic rod 21 from extending further without manual operation when the alarm sounds, in an embodiment of the present application, the stop body 26 is also provided with a second button switch 262, and the second button switch 262 is electrically connected to the first telescopic rod 21, so that the first telescopic rod 21 can be stopped after the first telescopic rod 21 pushes the second button switch 262. The second button switch 262 can also close or disconnect the metal contacts inside it when it is pressed or released, and the second button switch 262 can also automatically return to the initial position after being released; the second button switch 262 is electrically connected to the first telescopic rod 21, and when the first telescopic rod 21 contacts the second button switch 262 and continues to extend downward to push the second button switch 262, the extension action of the first telescopic rod 21 will be stopped; wherein, the first telescopic rod 21 can contact the first button switch 261 first, or can contact the first button switch 261 and the second button switch 262 at the same time, so that the first telescopic rod 21 will stop moving and the alarm will also sound, which can remind the operator to determine whether the first telescopic rod 21 is extended in the non-working range due to a malfunction or extended due to an erroneous operation. It can be understood that the stopper 26 can be provided with a first groove and a second groove, one end of the first button switch 261 is provided in the first groove, and the other end extends out of the first groove.

[0041] In order to reduce the impact of the first telescopic rod 21 and the second telescopic rod 4 on the collision with other objects, after the outer peripheral wall of the first telescopic rod 21 and the outer peripheral wall of the second telescopic rod 4 touch other objects, the first telescopic rod 21 and the second telescopic rod 4 can still continue to move with the tool cart 2. In another embodiment of the present application, the electrolytic aluminum anode height measuring device also includes a first yielding body 25, which is rotatably installed on the tool cart 2 around a first axis, and the first axis extends along the length direction of the first telescopic rod 21 and is arranged at an angle to the first yielding body 25. The retractable rod 21 is connected to the first yielding body 25 and is spaced apart from the first axis; thus, when the tool cart 2 is moving, the outer peripheral wall of the first telescopic rod 21 collides with other objects, causing the first yielding body 25 to rotate, and the first yielding body 25 drives the first telescopic rod 21 to rotate and detach from other objects, thereby reducing the time for the outer peripheral wall of the first telescopic rod 21 to collide with other objects, reducing the impact of the impact force on it, and during the movement of the tool cart 2, it can prevent the first telescopic rod 21 from being blocked by other objects for a long time, thereby preventing the tool cart 2 from being pulled by the first telescopic rod 21. The electrolytic aluminum anode height measuring device also includes a second yielding body 24, which is rotatably mounted on the tool cart 2 around a second axis, the second axis extends along the length direction of the second telescopic rod 4 and is arranged at an angle to the second yielding body 24, and the second telescopic rod 4 is connected to the second yielding body 24 and is spaced apart from the second axis. In this way, during the movement of the tool cart 2, after the outer peripheral wall of the second telescopic rod 4 collides with other objects, the second yielding body 24 will rotate, and the second yielding body 24 will drive the second telescopic rod 4 to rotate and separate from other objects, thereby reducing the time when the outer peripheral wall of the second telescopic rod 4 collides with other objects and reducing the impact of the impact force on it. In addition, during the movement of the tool cart 2, it can prevent the second telescopic rod 4 from being blocked by other objects for a long time, thereby preventing the tool cart 2 and the second telescopic rod 4 from being pulled.

[0042] When the object colliding with the first telescopic rod 21 is larger in horizontal dimension and exceeds the rotation area of ​​the first giving way body 25, the first giving way body 25 still fails to move the first telescopic rod 21 and the tool cart 2 away from the object after rotation. In order to allow the first telescopic rod 21 to smoothly separate from the object, in an embodiment of the present application, the first telescopic rod 21 is connected to the first giving way body 25 by rotation around a third axis, and the third axis is perpendicular to the first axis; when the first telescopic rod 21 collides with the object, the first telescopic rod 21 will rotate, and the bottom of the first telescopic rod 21 will reach the top of the object. As the tool cart 2 moves forward, the bottom of the first telescopic rod 21 will pass through the top of the object and separate from the resistance of the object. When the object colliding with the second telescopic rod 4 is larger in horizontal dimension and exceeds the rotation area of ​​the second giving way body 24, the second giving way body 24 still fails to move the second telescopic rod 4 and the tool cart 2 away from the object after rotation. In order to allow the second telescopic rod 4 to smoothly separate from the object, in an embodiment of the present application, the second telescopic rod 4 is connected to the second giving way body 24 by rotation around a fourth axis, and the fourth axis is perpendicular to the second axis; when the second telescopic rod 4 collides with the object, the second telescopic rod 4 will rotate, and the bottom of the second telescopic rod 4 will reach the top of the object. As the tool cart 2 moves forward, the bottom of the second telescopic rod 4 will pass the top of the object and separate from the resistance of the object.

[0043] In the embodiment of the present application, the tool vehicle 2 is provided with a speed sensor 23 , and the speed sensor 23 is electrically connected to the first telescopic rod 21 and the second telescopic rod 4 . By setting the speed sensor 23, the moving speed of the tool cart 2 can be detected, and when the moving speed of the tool cart 2 exceeds the preset speed, a high-speed signal can be sent to the first telescopic rod 21 and the second telescopic rod 4, and the first telescopic rod 21 and the second telescopic rod 4 will not be able to extend according to the high-speed signal, and when the moving speed of the tool cart 2 is less than the preset speed, the speed sensor 23 sends a low-speed signal to the first telescopic rod 21 and the second telescopic rod 4, and the first telescopic rod 21 and the second telescopic rod 4 will extend according to the low-speed signal; in this way, the tool cart 2 can carry the first telescopic rod 21 and the second telescopic rod 4 to move safely and quickly in the non-working range, and can quickly reach the working range, which can prevent the first telescopic rod 21 and the second telescopic rod 4 from being damaged by a large impact force after colliding with other objects due to excessive speed; of course, the tool cart 2 can also move in the non-working range at a slower speed; wherein, when the tool cart 2 is at the preset speed, the first telescopic rod 21 and the second telescopic rod 4 are subjected to a small impact force after being collided and will not be damaged.
