DETAILED DESCRIPTION

[0029] The specific embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0030] In the description of the present disclosure, it should be understood that the directions or positional relationships indicated by the terms "upper" and "lower" are defined based on the drawing directions shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, and a specific direction structure and operation, and therefore cannot be understood as a limitation of the present disclosure. Optionally, the directions of upper and lower can be the same as the directions of the upper and lower directions of the vehicle when the vehicle is in normal driving state. The terms "inside and outside" refer to the inside and outside of the corresponding structural contour.

[0031] In this disclosure, the specific directions of the height direction and the width direction can be seen Figure 1 .

[0032] In the present disclosure, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element, and do not have order and importance. In addition, in the description with reference to the drawings, the same number in different drawings represents the same element.

[0033] 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.

[0034] When a high-voltage switch cabinet is subjected to power outage inspection and maintenance, the prior art is to manually pull the trolley circuit breaker installed in the high-voltage distribution cabinet out of the cabinet through a guide plate, and the trolley can only move forward and backward without a steering function. In the narrow space of the distribution room, its forward direction can only be changed by manpower to move to a designated location outside the cabinet. In addition, the switches of trolleys of different models are of different sizes, and the guide plate needs to be replaced frequently to suit different trolleys.

[0035] The overall weight of a trolley circuit breaker is generally around 300-400kg. When the circuit breaker trolley is moved from the ground to the cabinet, there is a certain height difference between the front edge of the distribution cabinet and the trolley guide rail in the cabinet. The existing method is to set a steel ramp plate (guide plate) with a certain angle in front of the cabinet, that is, the guide plate of the trolley. It needs to be pushed from the ground to the track in the distribution cabinet by multiple people. When moving on the ground, the four wheels of the trolley are in greater contact with the ground, requiring a large manual external force to pull. Generally, two to three people are required to cooperate when operating the trolley circuit breaker, which is difficult to operate, time-consuming and laborious. When moving the trolley circuit breaker, due to the large inertia, the guide plate is rolled for a long time, and the guide plate is very easy to deform and prone to danger. There are safety hazards in the operation, and the guide plate needs to be moved once for each operation, which has low work efficiency. At present, most of the distribution room floors are epoxy self-leveling floors. If this kind of floor rubs against hard objects, it is very easy to leave scratches, which affects the appearance and is not conducive to later sanitation and cleaning.

[0036] In view of this, if Figure 1 and Figure 2As shown, the present disclosure provides a traction device for a trolley circuit breaker, comprising a support member 10, a mounting frame 20 and a guide member 30. The mounting frame 20 is used to mount the support member 10 and the guide member 30. The support member 10 is suitable for supporting the trolley circuit breaker. The guide member 30 is provided with a guide groove 31, which is adapted to the guide rail of the trolley circuit breaker and is suitable for matching with the track on the switch cabinet. The mounting frame 20 is provided with a driving mechanism 50 and a connecting member 23. The connecting member 23 is used to mount the guide member 30. The driving mechanism 50 is in transmission connection with the connecting member 23 and can drive the connecting member 23 to move along the height direction of the traction device.

[0037] In the present disclosure, the mounting frame 20 is used as the basic support of the traction device for installing the guide member 30 and the support member 10. The support member 10 is used to bear the weight of the trolley circuit breaker, and the guide member 30 is used to adapt to the guide rail of the trolley circuit breaker. When the trolley circuit breaker is moved, the weight of the trolley circuit breaker is supported by the support member 10, and the guide member 30 will not be crushed for a long time. The mounting frame 20 is provided with a connecting member 23 for installing the guide member 30, and the guide member 30 is connected to a driving device, which can drive the connecting member 23 to move along the height direction of the traction device, so that the guide member 30 can be installed along the height direction of the traction device with the connecting member 23. Therefore, when installing the trolley circuit breaker into the switch cabinet or removing it from the switch cabinet, the traction device can be used to push the trolley circuit breaker to the position of the switch cabinet, that is, to lift the trolley circuit breaker to a preset height. The guide member 30 is provided with a guide groove 31 which is adapted to the guide rail of the trolley on the trolley circuit breaker, and the guide rail is adapted to the track on the switch cabinet. After the guide groove 31 and the guide rail are connected, they can limit each other. Since there is a certain height difference between the switch cabinet and the ground, the driving device can be used to drive the connecting member 23 to move up or down along the height direction of the traction device. The guide member 30 can move up or down with the connecting member 23, and the trolley circuit breaker on the guide member 30 can be moved accordingly to be flush with the installation position of the switch cabinet. The operator does not need to use hand pulling, and the trolley circuit breaker can be installed or removed in the switch cabinet in a time-saving and labor-saving manner. The guide member 30 is not easy to deform, and the operation is safe.

[0038] In the present disclosure, the track on the switch cabinet refers to the part of the switch cabinet that is adapted to the guide rail of the trolley circuit breaker. When the trolley circuit breaker is installed on the switch cabinet, the guide rail of the trolley circuit breaker is connected to the track on the switch cabinet. Here, since the guide rails are different due to the different models of the trolley circuit breaker, the shape of the guide groove 31 is not limited, and the two can be adapted.

[0039] In the present disclosure, the support member 10 can bear the weight of the trolley circuit breaker, and is mainly used to bear the weight of the trolley circuit breaker when the trolley circuit breaker is pushed. This design can prevent the guide member 30 used to increase the height of the trolley circuit breaker from being crushed for a long time when the trolley circuit breaker is pushed, and effectively avoids deformation of the guide member 30.

[0040] In the present disclosure, optionally, the connecting member 23 is arranged to extend along the width direction of the traction device, and a sleeve portion is provided on the guide member 30, and the sleeve portion is slidably sleeved on the connecting member 23 along the width direction of the traction device. In order to adapt to various types of trolleys and installation cabinets, the position of the guide member 30 along the width direction of the traction device can be adjusted to adapt to different trolley circuit breakers.

[0041] like Figure 2 As shown, the sleeve portion is sleeved on the connecting member 23, and the position of the sleeve portion and the connecting member 23 in the rotation direction is fixed here. The fixation here can be fixed by limiting the angular position between the sleeve portion and the connecting member 23, but the shape of the cross-section of the sleeve portion here is not limited. As long as there are edges so that the circumferential limitation is completed after the two are sleeved, it is ensured that the sleeve portion will not rotate on the connecting member 23.

[0042] Here, there is no limitation on the number of guide members 30. When in use, because the models or manufacturers of the trolley circuit breakers are different, the number of guide members 30 can be set according to the number of guide rails of the trolley circuit breaker.

[0043] In the present disclosure, the number of guide members 30 can be set to two, and the two guide members 30 are arranged along the width direction of the traction device. In order to adapt to conventional trolley circuit breakers, the number of guide members 30 can be set to two. Since the guide members 30 can be adjusted along the width direction of the traction device, the spacing between the two guide members 30 can be adjusted, so that it can be used for various types of trolley circuit breakers. In addition, even if there are multiple (more than two) guide rails on the trolley circuit breaker, two of the guide rails can be adjusted and adapted for use. The two guide members 30 can ensure force balance, and the trolley circuit breaker is not prone to tilting.

[0044] In the present disclosure, in order to ensure the strength of the connecting member 23, the connecting member 23 can be set as a frame structure, including a first rod 231, a second rod 232 and two sliding rods 233 connected to each other, the first rod 231 and the second rod 232 are arranged in parallel and arranged along the width direction of the traction device, the first rod 231 is used to install the guide member 30, the second rod 232 is connected to the driving mechanism 50 by transmission, the two sliding rods 233 are connected between the first rod 231 and the second rod 232, and the first rod 231 and the second rod 232 form a frame structure, and the sliding rods 233 are slidably connected to the mounting frame 20 along the height direction of the traction device. The connecting member 23 is used to connect the guide member 30. When the trolley circuit breaker is placed in the switch cabinet, the guide member 30 needs to bear the weight of the trolley circuit breaker. The guide member 30 is sleeved on the connecting member 23, so the connecting member 23 also needs to bear the weight of the trolley circuit breaker. Setting the connecting member 23 as a frame structure can ensure the bearing strength of the connecting member 23.

[0045] like Figure 2 As shown, the sleeve portion of the guide member 30 may be provided with a notch, which can accommodate the first rod 231 to pass through, so that the guide member 30 can not only slide on the first rod 231, but also be conveniently installed and removed from the first rod 231 through the notch.

[0046] In the present disclosure, the support member 10 may include two support plates 11, which are arranged along the width direction of the traction device and are respectively connected to the mounting frame 20. In the width direction of the traction device, the guide member 30 is located between the two support plates 11, and the support plate 11 is provided with a locking member 12 suitable for locking the trolley circuit breaker. The support plate 11 is used to bear the weight of the trolley circuit breaker. The two support plates 11 can ensure the balanced support of the trolley circuit breaker. The guide member 30 is located between the two support plates 11 so that the support position of the support member 10 is located on both sides of the trolley circuit breaker, which will not affect the guide rail of the trolley circuit breaker and can avoid damage to the guide rail. The function of the locking member 12 is to lock and position the traction device and the trolley circuit breaker, which is helpful to avoid the risk of the trolley circuit breaker slipping during the pushing process.

[0047] The present disclosure does not limit the specific structure of the locking member 12, and a commonly used locking member can be used for locking.

[0048] In the present disclosure, a rolling wheel 13 can be provided at the bottom of the support plate 11. A trolley circuit breaker is generally provided with a moving wheel, which can be used to directly pull the trolley circuit breaker. The rolling wheel 13 provided on the traction device can make the weight of the trolley circuit breaker press on the rolling wheel 13. Even if the rolling wheel 13 is damaged, it is convenient to replace it, and the moving wheel on the trolley circuit breaker can be prevented from being damaged. The rolling wheel here can be set as a universal wheel, which is convenient for steering when pushing.

[0049] In the present disclosure, the mounting frame 20 may include a connecting rod 22 and two mounting rods 21, the two mounting rods 21 are arranged along the width direction of the traction device, each mounting rod 21 is used to be connected to the corresponding support plate 11, and both ends of the connecting rod 22 are fixedly connected to the lower ends of the two mounting rods 21. The function of the mounting rod 21 is to connect the support plate 11, and its structure can be set corresponding to the support plate 11. The function of the connecting rod 22 is to connect the two mounting rods 21 into one body to form the basic frame of the mounting frame 20. The connecting rod 22 is connected to the lower ends of the two mounting rods 21, so that the connecting rod 22 can further fix the position of the support plate 11 while connecting the mounting rods 21.

[0050] Here, the position and structure of the connecting member 23 sliding on the mounting frame 20 are not limited, as long as the connecting member 23 can slide in the height direction of the traction device.

[0051] In the present disclosure, a slide groove 212 may be provided on the mounting rod 21 in the vertical direction, and the slide groove 212 is suitable for accommodating a sliding rod 233, and the sliding rod 233 can slide along the slide groove 212 under the action of the driving mechanism 50. The slide groove 212 is provided so that the sliding rod 233 can be accommodated (limited) inside the slide groove 212, and both sliding rods 233 are limited in the slide groove 212, which is conducive to ensuring that the connecting member 23 is not easy to slide out of the slide groove 212 when sliding.

[0052] In the present disclosure, the mounting frame 20 may further include a reinforcing rod 24, the two ends of which are connected to the upper ends of the two mounting rods 21; the reinforcing rod 24 is provided with a through hole 241 through which the connecting member 23 can pass. The mounting frame 20 can be designed as a frame structure by connecting the reinforcing rod 24, which has good stability. In addition, the reinforcing rod 24 is provided with a through hole 241 through which the connecting member 23 can pass, which can facilitate the installation of the connecting member 23 and the repair and replacement of the connecting member 23 after it is damaged.

[0053] In the present disclosure, the driving mechanism 50 may include a hydraulic cylinder, the piston rod of which is connected to the connecting member 23 to drive the connecting member 23 to move in the height direction of the traction device; the cylinder body of the hydraulic cylinder is connected to the connecting rod 22. The driving device is set as a hydraulic cylinder for easy installation. The piston rod may be connected to the second rod 232 of the connecting member 23, and the cylinder body of the hydraulic cylinder is connected to the connecting rod 22. The distance between the connecting rod 22 and the second rod 232 is relatively close, which facilitates the arrangement of the hydraulic cylinder and the piston rod.

[0054] In this disclosure, Figure 1 As shown, a hand pull ring 40 may be provided on the mounting frame 20 for the convenience of the operator.

[0055] The existing trolley circuit breaker base is supported by a total of four fixed wheels, and can only move up and down the high-voltage distribution cabinet along the guide plate. This traction device uses a hydraulic cylinder to raise the trolley circuit breaker to a certain height and then push it parallel to the trolley guide rail in the high-voltage distribution cabinet, thereby eliminating the risk of the trolley circuit breaker tilting or tilting due to the height difference. A guide member that can move along the width direction of the traction device is provided to adapt to trolleys of different models and specifications, reducing the workload of replacing the guide member. The guide member here can act as a guide plate. In addition, a universal wheel is provided to improve the convenience and safety of operation, eliminate the safety hazards caused by the heavy weight of the trolley, and improve work efficiency. The traction device can improve work efficiency. It avoids the occurrence of trolley damage due to improper operation and excessive force, which is conducive to avoiding dangerous safety hazards when personnel move the trolley, and preventing the occurrence of ground wear problems caused by large manpower dragging the trolley, thereby improving the convenience and safety of trolley switch operation.
