DETAILED DESCRIPTION

[0024] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0025] In the present disclosure, it is to be understood that the directional words used, such as "up and down direction, front and back direction, left and right direction" are usually in the form of Figure 1 The directions shown are defined only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, and a specific orientation structure and operation, and therefore cannot be understood as a limitation of the present disclosure. The terms "inside and outside" refer to the inside and outside of the corresponding structural contour. In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another, and do not have order and importance. In addition, in the description of the reference drawings, the same marks in different drawings represent the same elements.

[0026] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0027] like Figures 1 to 4 As shown, the present disclosure provides a switch transport vehicle 100, including a vehicle body 10, moving wheels 20, a lifting structure 30, a first driving mechanism 40, a switch gripping structure 50 and a second driving mechanism 60, wherein the moving wheels 20 are arranged at the bottom of the vehicle body 10, the lifting structure 30 is movably arranged on the vehicle body 10 in the up-down direction, the lifting structure 30 is suitable for carrying a switch, the first driving mechanism 40 is installed on the vehicle body 10, the first driving mechanism 40 is connected to the lifting structure 30 and is used to drive the lifting structure 30 to reciprocate in the up-down direction, the switch gripping structure 50 is movably arranged on the lifting structure 30 in the front-to-back direction, the switch gripping structure 50 is constructed to be able to be unlockably locked to the handle 13 of the switch, the second driving mechanism 60 is installed on the lifting structure 30, the second driving mechanism 60 is connected to the switch gripping structure 50 and is used to drive the switch gripping structure 50 to reciprocate in the front-to-back direction, so that the switch gripping structure 50 can pull the switch out of the switch cabinet to the lifting structure 30 or push the switch from the lifting structure 30 into the switch cabinet.

[0028] In the above-mentioned switch transport cart 100, since the first driving mechanism 40 is connected to the lifting structure 30 and is used to drive the lifting structure 30 to reciprocate in the up and down directions, the lifting structure 30 can adjust the height of the lifting structure 30 under the action of the first driving mechanism 40, so that the lifting structure 30 can be suitable for switches located at different heights, and the switch transport cart 100 has high versatility.

[0029] Through the above technical solution, since the vehicle body 10 is provided with moving wheels 20, the lifting structure 30 for installing the switch gripping structure 50 is movably arranged on the vehicle body 10 in the up-down direction, and the switch gripping structure 50 is movably arranged on the lifting structure 30 in the front-back direction. In this way, when it is necessary to operate and transport the switch (such as a high-voltage switch) in the switch cabinet, the operator can move the vehicle body 10 to the front of the switch cabinet through the moving wheels 20, adjust the position of the lifting structure 30 through the first driving mechanism 40, so that the switch gripping structure 50 arranged on the lifting structure 30 can be in the same plane as the switch to be operated and maintained, and drive the switch gripping structure 50 to move in a direction close to the switch through the second driving mechanism 60, and lock the switch gripping structure 50 to the handle 13 of the switch. After the switch gripping structure 50 locks the handle 13 of the switch, the switch gripping structure 50 is driven by the second driving mechanism 60 to move in a direction away from the switch, so that the switch can be pulled out of the switch cabinet to the lifting structure 30, and the switch can be transported by moving the vehicle body 10 later.

[0030] Compared with the technical solution of using manpower to move the high-voltage switch in the related art, the switch transport vehicle 100 disclosed in the present invention does not require manpower to move the switch during the process of pulling out, pushing in and moving the switch, and the switch transport process is relatively simple. In addition, during the transport process, the switch gripping structure 50 can pull the switch out onto the lifting structure 30, and the lifting structure 30 carries the switch, which can prevent the switch from falling and being damaged during the transport process, or damaging the electrical components around the power cabinet.

[0031] In addition, since the switch gripping structure 50 is constructed to be unlockably locked to the handle 13 of the switch, during the movement of the switch, the connection between the switch gripping structure 50 and the handle 13 of the switch is reliable, and the switch gripping structure 50 is not easy to separate from the handle 13 of the switch, which effectively avoids the switch gripping structure 50 from separating from the switch, resulting in the switch in the switch cabinet being unable to be taken out or pushed in.

[0032] In order to facilitate pulling the switch onto the lifting structure 30, optionally, as Figures 1 to 3As shown, the lifting structure 30 includes a bearing platform 31 and an insertion portion 32 disposed on the bearing platform 31, the first driving mechanism 40 is connected to the bearing platform 31, the switch gripping structure 50 is movably disposed on the bearing platform 31 along the front-back direction, the rear end of the insertion portion 32 is connected to the front end of the bearing platform 31, and the insertion portion 32 is used to be inserted into the gap below the switch, wherein the thickness of the insertion portion 32 gradually increases along the direction from the front end of the insertion portion 32 to the rear end of the insertion portion 32. Since the lifting structure 30 includes the bearing platform 31, the bearing platform 31 can support the switch during the movement and operation and maintenance of the switch, and the switch is not easy to fall from the transport vehicle.

[0033] In addition, since the lifting structure 30 also includes an insertion portion 32 arranged on the supporting platform 31, and the thickness of the insertion portion 32 gradually increases from the front end of the insertion portion 32 to the rear end of the insertion portion 32, in other words, the cross-section of the insertion portion 32 is constructed as a trapezoid or a triangle. In this way, when the supporting platform 31 is inserted into the cabinet body of the switch cabinet, the insertion portion 32 can be smoothly inserted into the gap under the switch, so that the supporting platform 31 can be located below the switch, so that the switch can be smoothly moved onto the supporting platform 31.

[0034] To improve the safety of the switch during transportation, you can choose to Figure 1 , Figure 3 and Figure 4 As shown, the lifting structure 30 further includes two side panels 33 spaced apart in the left-right direction, the lower ends of the two side panels 33 are connected to the carrying platform 31, and the height of the upper ends of the side panels 33 is higher than the height of the upper surface of the switch gripping structure 50. Since the side panels 33 are provided at both the left and right ends of the carrying platform 31, the two side panels 33 can block and protect the switch during transportation, effectively preventing the switch from falling off the side panels 33. In addition, the side panels 33 can also prevent the switch from colliding with the surrounding electrical components during movement, thereby causing damage to the surrounding electrical components.

[0035] In addition, since the height of the upper end of the side panel 33 is higher than the height of the upper surface of the switch gripping structure 50, in other words, the height of the side panel 33 is higher than the height of the handle 13 of the switch, even if the switch collides with the side panel 33 due to shaking, the switch is not likely to roll off from the side panel 33, and the side panel 33 has a better protective effect on the switch.

[0036] To reduce the wear of the switch during transportation, it is optional to Figure 2 and Figure 3As shown, the lifting structure 30 is provided with a plurality of pulleys 70, which are arranged at intervals along the front-back direction, and the pulleys 70 are used to roll in contact with the bottom of the switch. In this way, when the switch in the switch cabinet moves on the bearing platform 31 under the action of the switch gripping structure 50, the switch can roll in contact with the pulley 70, and the switch will not rub against the bearing platform 31. In this way, on the one hand, the friction force during the movement of the switch can be reduced, and the second driving mechanism 60 only needs a smaller driving force to drive the switch to move; on the other hand, it can also reduce the wear of the switch and increase the service life of the switch.

[0037] It should be noted that the present disclosure does not limit the specific structure of the vehicle body 10. As an embodiment of the present disclosure, Figure 1 , Figure 2 and Figure 4 As shown, the vehicle body 10 includes a base 11, a support frame 12 and a handle 13, the moving wheel 20 is installed at the bottom of the base 11, the base 11 includes two first bottom plates 111 spaced apart in the left-right direction and a second bottom plate 112 connected between the two first bottom plates 111, the two first bottom plates 111 and the second bottom plate 112 constitute a U-shaped structure with an opening toward the switch cabinet, and the inner side of the U-shaped structure is suitable for accommodating at least part of the lifting structure 30, wherein the support frame 12 extends in the up-down direction and is connected to the second bottom plate 112, the first driving mechanism 40 is installed on the support frame 12, and the handle 13 is arranged on the upper part of the support frame 12, wherein at least part of the first bottom plate 111 is suitable for inserting into the gap between the cabinet body of the switch cabinet and the ground, or the U-shaped structure enables the cabinet body of the switch cabinet to enter the U-shaped structure from the opening of the U-shaped structure.

[0038] The base 11 and the support frame 12 can jointly support the lifting structure 30, the first drive mechanism 40 and the second drive mechanism 60 provided on the lifting structure 30, so that the switch transport vehicle 100 is more stable and less likely to shake. At the same time, the U-shaped structure on the base 11 can also store the lifting structure 30, which is conducive to improving the space utilization rate of the entire switch transport vehicle 100 and facilitating storage.

[0039] Furthermore, since the two first bottom plates 111 and the second bottom plate 112 of the base 11 form a U-shaped structure with an opening toward the switch cabinet, and at least a portion of the first bottom plate 111 is suitable for being inserted into the gap between the cabinet body of the switch cabinet and the ground, or the U-shaped structure enables the cabinet body of the switch cabinet to enter the U-shaped structure from the opening of the U-shaped structure. In other words, when the switch is moved by the switch transporter 100, the distance between the transporter and the cabinet body of the switch cabinet can be reduced by reasonably adjusting the position of the base 11, thereby facilitating the contact between the lifting structure 30 and the switch grasping structure 50 arranged on the lifting structure 30 and facilitating the transportation of the switch, and effectively avoiding the situation where the switch grasping structure 50 is far away from the switch in the switch cabinet and the switch transporter 100 cannot move the switch in the switch cabinet.

[0040] In addition, since the support frame 12 is also provided with a handle 13, when the switch transport vehicle 100 is moved, the entire switch transport vehicle 100 can be pushed to move by simply holding the handle 13, and the movement of the switch transport vehicle 100 is relatively convenient.

[0041] For an embodiment in which the vehicle body 10 includes a base 11, and the two first bottom plates 111 and the second bottom plates 112 of the base 11 form a U-shaped structure, optionally, as Figure 1 , Figure 3 and Figure 4 As shown, the lifting structure 30 includes a load-bearing platform 31 and two side panels 33 spaced apart in the left-right direction, the lower ends of the two side panels 33 are connected to the load-bearing platform 31, and the upper ends of the two side panels 33 are folded outward to form support flanges 34, and the two support flanges 34 are used to be supported on the two first bottom plates 111 when the load-bearing platform 31 is accommodated inside the U-shaped structure. The two side panels 33 can block and protect the switch, effectively preventing the switch from falling off the side panels 33, and the safety of the switch handling process is relatively high.

[0042] Furthermore, since the upper ends of the two side panels 33 are folded outward to form supporting flanges 34, and the two supporting flanges 34 are used to respectively support the two first bottom plates 111 when the supporting platform 31 is accommodated on the inner side of the U-shaped structure, the U-shaped structure on the base 11 can support and limit the supporting platform 31, and the supporting platform 31 is not easy to collide and rub against the ground, which is beneficial to improve the service life of the supporting platform 31.

[0043] In addition, when the carrying platform 31 is stored, there is no need to keep the first driving device powered on. The carrying platform 31 can be supported by the two first bottom plates 111 by simply lowering its height, which is beneficial for saving energy consumption.

[0044] Alternatively, if Figure 1 , Figure 3 and Figure 4As shown, both support flanges 34 are formed with chamfers. The support flanges 34 formed with guide feet can guide the carrying platform 31, so that even if there is a certain offset between the switch transport vehicle 100 and the door of the switch cabinet, the support flanges 34 can guide the carrying platform 31 to be inserted into the cabinet door of the cabinet, thereby facilitating the transportation of the switch.

[0045] The present disclosure does not limit the specific structure of the switch gripping structure 50, as long as the switch gripping structure 50 can be reliably locked to the handle 13 of the switch. As an implementation method of the present disclosure, Figures 1 to 3 As shown, the switch grasping structure 50 includes a moving seat 51, a mechanical claw 52 and an actuator. The moving seat 51 is movably arranged on the lifting structure 30 along the front-to-back direction. The second driving mechanism 60 is connected to the moving seat 51. The mechanical claw 52 is installed on the moving seat 51. The mechanical claw 52 includes a fixed claw 521 and a movable claw 522. The fixed claw 521 and the movable claw 522 are relatively arranged along the up-down direction. The actuator is arranged in the moving seat 51. The actuator is connected to the movable claw 522 and is used to drive the movable claw 522 to move or rotate in a direction close to or away from the fixed claw 521, so that the mechanical claw 52 can grasp or release the handle 13.

[0046] Since the mechanical claw 52 includes a fixed claw 521 and a movable claw 522, the fixed claw 521 and the movable claw 522 are arranged relatively to each other in the up and down directions, and the actuator arranged in the movable seat 51 is used to drive the movable claw 522 to move or rotate. In this way, when it is necessary to move (i.e. pull out or push in, etc.) the switch in the switch cabinet, the operator can first operate the second driving mechanism 60 to move the movable seat 51 toward the direction close to the handle 13 of the switch. When the mechanical claw 52 is close to the handle 13 of the switch, the operator can operate the actuator to move or rotate the movable claw 522 so that the movable claw 522 and the fixed claw 521 can grasp the handle 13 together. At this time, the movement of the switch can be realized by operating the second driving mechanism 60, and the movement of the switch is relatively simple.

[0047] For the embodiment in which the actuator is disposed in the movable seat 51, and the actuator is connected to the movable claw 522 and is used to drive the movable claw 522 to rotate toward or away from the fixed claw 521, optionally, as Figure 2As shown, a matching bevel 523 may be formed on the fixed claw 521, and the matching bevel 523 is located on the surface of the fixed claw 521 on the side close to the movable claw 522, and the matching bevel 523 is inclined toward the side away from the movable seat 51. In this way, when the movable claw 522 is pressed against the fixed claw 521 under the action of the actuator, the matching bevel 523 formed on the fixed claw 521 can form a surface-to-surface contact with the movable claw 522, and the contact area between the fixed claw 521 and the movable claw 522 is large, which is conducive to improving the gripping effect of the movable claw 522 and the fixed claw 521 on the handle 13 of the switch.

[0048] The present disclosure does not limit the specific type of the actuator. As an embodiment of the present disclosure, the actuator can be constructed as a rotary motor, which can drive the movable claw 522 to rotate, so that the mechanical claw 52 can grasp or release the handle 13.

[0049] As another embodiment, the actuator may also be configured as a linear motor, which can also drive the movable claw 522 to move toward or away from the fixed claw 521 , so that the mechanical claw 52 can grasp or release the handle 13 .

[0050] It should be noted that the switch gripping structure 50 of the present disclosure is not limited to the form of the mechanical claw 52. As other embodiments of the present disclosure, the switch gripping structure 50 may also include a moving seat 51, a hook ring, and a rotating motor. The second drive mechanism 60 is connected to the moving seat 51, the hook ring is installed on the moving seat 51, and the rotating motor is arranged in the moving seat 51. The rotating motor is connected to the movable claw 522 and is used to drive the hook ring to rotate so that the mechanical claw 52 can hook or release the handle 13. In this way, when it is necessary to move (i.e. pull out or push in, etc.) the switch in the switch cabinet, the operator can first operate the second drive mechanism 60 to move the moving seat 51 toward the direction close to the handle 13 of the switch. When the hook ring is close to the handle 13 of the switch, the operator can operate the rotating motor to rotate the hook ring so that the hook ring hooks the handle 13. At this time, the second drive mechanism 60 can be operated to realize the movement of the switch, and the movement of the switch is relatively simple.

[0051] For the embodiment in which the switch gripping structure 50 includes a movable seat 51, a mechanical claw 52, ​​and an actuator, the present disclosure does not limit the specific number of the mechanical claws 52. The mechanical claw 52 may be one or more than one. As an embodiment of the present disclosure, the number of the mechanical claws 52 is multiple, and the multiple mechanical claws 52 are all installed on the movable seat 51, and the multiple mechanical claws 52 are arranged at intervals along the left and right directions. In this way, during the movement of the switch, the handle 13 on the switch can be gripped by multiple mechanical claws 52 at the same time. On the one hand, the multiple mechanical claws 52 can make the force on the handle 13 uniform, effectively avoiding the situation where one side of the handle 13 is subjected to greater force, resulting in easy displacement when the switch moves; on the other hand, the multiple mechanical claws 52 can also improve the connection reliability between the switch gripping structure 50 and the handle 13.

[0052] The present disclosure does not limit the specific manner in which the actuator drives the mechanical claw 52 to move. As an embodiment of the present disclosure, the number of the above-mentioned actuator is one, and one actuator is simultaneously connected to multiple mechanical claws 52. In this way, one actuator can drive multiple mechanical claws 52 to grasp or release the handle 13 of the switch, which is conducive to simplifying the structure of the switch grasping structure 50 and reducing the cost of the switch grasping structure 50.

[0053] Alternatively, if Figure 1 As shown, the lifting structure 30 further includes a back plate 35, which is disposed on a side away from the switch gripping structure 50, and the first driving mechanism 40 is connected to the back plate 35, the lower end of the back plate 35 is connected to the bearing platform 31, and the two sides of the back plate 35 are respectively connected to the two side plates 33. The first driving mechanism 40 is connected to the bearing platform 31 through the back plate 35, and the back plate 35 can separate the first driving mechanism 40 and the second driving mechanism 60, so that the first driving mechanism 40 will not interfere with the second driving mechanism 60.

[0054] The present disclosure does not limit the specific structure of the first driving mechanism 40. Optionally, as an embodiment of the present disclosure, the first driving mechanism 40 includes a first motor 41, a screw 42, a first nut 43 and a first slider 44. The first slider 44 has two first sliding parts 45. Two first slide grooves 14 are formed on the vehicle body 10. The first slide grooves 14 extend in the up-down direction. The two first sliding parts 45 pass through the first slide grooves 14 and are connected to the lifting structure 30. The screw 42 is installed on the vehicle body 10. The first nut 43 is axially locked and circumferentially rotatably installed on the first slider 44. The first nut 43 is threadedly connected to the screw 42. The first motor 41 is installed on the first slider 44 and connected to the first nut 43. The first motor 41 is used to drive the first nut 43 to rotate. Here, the first motor 41 can drive the first nut 43 to rotate through a transmission mechanism (such as a gear set).

[0055] Since the first nut 43 is connected to the first motor 41, the first nut 43 is axially locked and circumferentially rotatably installed on the first slider 44, and the screw 42 threadedly connected to the first nut 43 is installed on the vehicle body 10. In this way, when the first motor 41 drives the first nut 43 to rotate, since the vehicle body 10 limits the circumferential rotation of the screw 42, the first nut 43 can move up and down on the screw 42, and since the two sliding parts of the first slider 44 pass through the first slide groove 14 and are connected to the lifting structure 30, the first slider 44 cannot rotate with the first nut 43. The first slider 44 can only move up and down under the action of the first nut 43, thereby driving the lifting structure 30 to move up and down.

[0056] In other embodiments, the first driving mechanism 40 may be a hydraulic cylinder, a scissor lift mechanism, an electric telescopic rod, or the like.

[0057] The present disclosure does not limit the specific structure of the second driving mechanism 60. As an implementation method of the present disclosure, Figure 3 As shown, the second driving mechanism 60 includes a second motor 61, a lead screw 62 and a second nut. A second slide slot 36 is formed on the lifting structure 30, and the second slide slot 36 extends in the front-back direction. The second motor 61 is connected to the lead screw 62 and is used to drive the lead screw 62 to rotate. The second nut is movably arranged in the second slide slot 36 and is sleeved on the lead screw 62. The switch gripping structure 50 is connected to the second nut. The lifting structure 30 includes a bearing platform 31 and a baffle 37. The second motor 61 and the baffle 37 are both installed on the bearing platform 31, and the baffle 37 is located between the second motor 61 and the switch gripping structure 50. Since the second motor 61 is connected to the lead screw 62 and is used to drive the lead screw 62 to rotate, and the second nut cannot rotate under the restriction of the switch gripping structure 50, the second nut can move along the lead screw 62, thereby pushing the switch gripping structure 50 to move.

[0058] In addition, since a baffle 37 is also provided between the second motor 61 and the switch gripping structure 50, when the switch gripping structure 50 moves toward the second motor 61, the baffle 37 can block the switch gripping structure 50, and the switch gripping structure 50 will not collide with the second motor 61, thereby effectively improving the service life of the switch gripping structure 50 and the second motor 61.

[0059] In other embodiments, the second driving mechanism 60 may also be an electric telescopic rod or the like.

[0060] The present disclosure does not limit the specific structure of the moving wheel 20. As an embodiment of the present disclosure, the moving wheel 20 includes a front wheel 21 and a rear wheel 22 arranged at intervals along the front-to-back direction. The rear wheel 22 is provided with a brake structure 23, and the brake structure 23 is configured to unlockably lock the rear wheel 22 to limit the rotation of the rear wheel 22. Since the brake structure 23 is provided on the rear wheel 22, when the switch transport vehicle 100 moves the switch, the operator can lock the rear wheel 22 through the brake structure 23. The brake structure 23 can limit the movement of the switch transport vehicle 100, and the switch transport vehicle 100 is not easy to shake, which effectively avoids the switch transport vehicle 100 shaking during the movement of the switch, causing the switch to shake, or even causing the switch to fall.

[0061] In order to facilitate the control of the switch transport vehicle 100, optionally, as Figure 1 , Figure 3 and Figure 4 As shown, the switch transport vehicle 100 further includes a control panel 80, which is disposed on the vehicle body 10 and is electrically connected to the first drive mechanism 40, the second drive mechanism 60 and the switch gripping structure 50. In this way, the first drive mechanism 40, the second drive mechanism 60 and the switch gripping structure 50 can be controlled through the control panel 80, and the control of the switch transport vehicle 100 is relatively simple.

[0062] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0063] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0064] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
