Description

Technical Field

[0001] The present invention relates to the field of transfer equipment, in particular to a leveling connection structure and a circuit breaker electric self-adjusting transfer trolley. Background Art

[0002] Because the circuit breaker is located in the center of the switchgear, removing the circuit breaker cart requires a special tool—a transfer cart. The transfer cart is designed to precisely match the height and width of the switchgear's circuit breaker compartment. To use it, first fine-tune the transfer platform using four adjustment bolts to ensure the locating posts precisely fit into the switchgear's locating holes. Once securely connected to the switchgear, the circuit breaker cart can be directly pulled onto the transfer cart to complete the operation.

[0003] There are many types of existing transfer carts, which occupy a large area. Due to different manufacturers, the models of switch cabinets vary. At the same time, due to the different sizes of switch cabinets for main transformers and lines, the lengths of their circuit breaker equipment carts vary, resulting in a large number of transfer cart types. In addition, the operation efficiency of transfer carts is low. Since the heights of switch cabinets are not completely consistent, the height of the transfer cart needs to be finely adjusted. The adjustment process relies entirely on manual judgment, which is time-consuming and labor-intensive. In addition, after operating the transfer cart to remove the circuit breaker, the horizontal angle of the circuit breaker needs to be adjusted to keep it in a horizontal position to prevent damage. Since circuit breakers vary in size, weight, and dimensions, the load capacity of the transfer cart is also limited. When the mass of the circuit breaker is too large, it is easy to cause the load platform to deform, resulting in the misalignment of the center axis between the electric cylinder push rod and the cylinder body used for adjustment. At this time, the friction between the electric cylinder push rod and the cylinder body increases, causing the service life of the electric cylinder to be greatly reduced.

[0004] Based on the above problems, we proposed a leveling connection structure and a circuit breaker electric self-adjusting transfer trolley. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is that the leveling equipment of the existing transfer vehicle is easily worn.

[0014] The beneficial effect of the leveling connection structure of the present invention is that by changing the fixed connection method of the raised end of the leveling member to a rotating connection method, the electric cylinder push rod and the cylinder center line can be more easily maintained coaxial, reducing the influence of external force on the movement, and making the leveling level more accurate, more convenient and smooth.

[0015] Another object of the present invention is to provide an electric self-adjusting transport trolley for a circuit breaker, the purpose of which is to solve the problem of low efficiency of existing transport trolleys.

[0041] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0042] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0043] Reference Figures 1 to 4 This embodiment provides a leveling connection structure, including a bearing assembly 1, including a receiving panel 11 for bearing the component to be transferred.

[0044] The receiving panel 11 is used to carry the components to be transferred, and the components to be transferred are mainly circuit breakers or any other components that need to be carried by the receiving panel 11.

[0045] The leveling component 2 includes a support platform 21 provided below the receiving panel 11 and a leveling member 22 provided between the support platform 21 and the receiving panel 11.

[0046] Preferably, four leveling components 2 are provided in this embodiment, corresponding to the four corners of the receiving panel 11 respectively, and different numbers of leveling components 2 can be set according to the difference of the receiving panel 11.

[0047] The support platform 21 is used to support the installation of the leveling member 22.

[0048] The leveling member 22 includes a push rod 221 movably connected to the support platform 21 and vertically arranged with respect to the receiving panel 11 and the support platform 21, and a contact head 222 rotatably connected to the push rod 221.

[0049] Wherein, a through hole penetrating the push rod 221 is formed at one end of the push rod 221 close to the receiving panel 11, the central axis of the through hole is parallel to the receiving panel 11, and the push rod 221 is rotatably connected to the contact head 222 through the through hole.

[0050] Wherein, the through hole at the end of the push rod 221 (such as the above position) can be replaced by a ball head or a ball shaft for rotatable connection with the contact head 222.

[0051] Wherein, the contact head 222 is fixedly connected to the receiving panel 11.

[0052] In summary, both the support platform and the receiving panel 11 are made by sheet metal welding processing. The two platforms have a relatively large width. Affected by factors such as the accuracy of the material itself and welding deformation, the flatness and roughness of the overall processed parts are not high. By the rotatable connection between the push rod 221 and the contact head 222, including flexible hinge connection and ball shaft connection, this kind of defect can be neutralized and the adaptability is strong. If a rigid connection is adopted, the processing and manufacturing accuracy requirements for the two platforms are high. That is, when the circuit breaker is placed on the receiving panel 11, the leveling member 22 needs to accurately adjust the horizontal angle. At this time, the horizontal accuracy of the leveling member 22 itself during installation can determine the horizontal accuracy of the receiving panel 11 that the leveling member 22 can adjust. If a fixed connection is adopted between the push rod 221 and the receiving panel 11, including but not limited to bolt connection, etc., subsequent finishing processes need to be added, increasing the manufacturing cost.

[0053] Refer to Figures 1 to 3 In an embodiment provided by the present application, the bearing component 1 further includes a receiving panel 12 provided below the receiving panel 11 and fixedly connected to the receiving panel 11, and a connecting panel 13 provided below the receiving panel 12 and fixedly connected to the receiving panel 12.

[0054] Combined with Figure 3It can be understood that the receiving panel 11 in the previous embodiment is only used as a bearing surface for carrying the circuit breaker. In this embodiment, a receiving panel 12 and a connecting panel 13 are arranged below the receiving panel 11 in sequence. Among them, a plurality of receiving spaces are opened inside the receiving panel 12, that is, the receiving panel 12 has a certain thickness to facilitate the installation of subsequent accessories.

[0055] In an embodiment provided by the present application, the connecting panel 13 is fixedly connected to the contact head 222.

[0056] Refer to Figures 3 to 4 , it can be understood that in this embodiment, the connecting panel 13 is fixedly connected to the receiving panel 12, and the receiving panel 12 is fixedly connected to the receiving panel 11. Among them, the contact head 222 can be replaced with the ball head or ball shaft structure in the first embodiment. The purpose is that the panel connected to the push rod 221 is in a rotatable connection state.

[0057] It should be noted that the bearing assembly 1 and the support platform 21 need to be kept parallel as much as possible. If the push rod 221 and the panel connecting the push rod 221 are in a fixed connection state at this time, there are requirements for the parallelism of the two planes of the bearing assembly 1 and the support platform 21 and the parallelism of the main central axes of the four lifting mechanisms to ensure the normal adjustment of the four-point mechanism. When using a flexible hinge or a ball head and ball shaft connection, the installation accuracy requirements can be reduced and the adaptability is strong.

[0058] Refer to Figures 1 to 4 In an embodiment provided by the present application, the connecting panel 13 coincides with the central axis of the push rod 221 in the non-deformed state, and the connecting panel 13 does not coincide with the central axis of the push rod 221 in the deformed state.

[0059] It should be noted that if the push rod 221 and the panel connected to the push rod 221 are in a fixed connection state at this time, and the four corners of the receiving panel 11 are recorded as points A, B, C, and D, when the horizontal state of the circuit breaker at this time needs to be adjusted, it is assumed that in the actual site, the receiving panel 11 is under the action of the gravity of the short circuit, so that the plane levelness point A is lower and needs to be raised. If a rigid connection is adopted, since the platform connected by the four points ABCD is a rigid hard plane, if only point A is lifted, the other three points are fixed, which will cause point A to be lifted alone, and the A end will be tilted, making leveling difficult; or at this time, when points B, C, and D are lifted at point A, points B, C, and D of the receiving panel 11 will be forcibly lifted, causing the push rod 221 to be forcibly separated from the cylinder 223 under the action of external force. Once the staff adjusts the angle too large and needs to adjust it in the opposite direction, the push rods 221 of the remaining B, C, and D points will return to the cylinder 223, and it cannot be guaranteed that the cooperation between the push rod 221 and the cylinder 223 will still remain good. It is very likely that under long-term action, the push rods 221 of the remaining B, C, and D points will lose the transmission connection with the cylinder 223 and permanently become a follow-up state, resulting in the inability to adjust the levelness of the remaining B, C, and D points, or a significant decrease in the accuracy of the levelness adjustment.

[0060] On the contrary, when a flexible hinge connection or a ball shaft connection is used, when the A end is lifted slightly, the other points in the connection between the hinge or ball shaft and the receiving panel 11 or the link panel 13 move accordingly, keeping the four points ABCD in the same plane, thereby ensuring the leveling accuracy and the service life of the leveling member 22.

[0061] In addition, in actual situations, it is possible that the mass of the circuit breaker is too large. At this time, when the circuit breaker is placed on the receiving panel 11, the receiving panel 11 will be deformed. In this embodiment, the outer diameter of the circuit breaker is smaller than the area enclosed by the leveling parts 2. That is, at this time, due to the excessive mass of the circuit breaker itself, the bearing capacity of the receiving panel 11 still exists, but the receiving panel 11 surrounded by the leveling parts 2 is recessed toward the ground. If a fixed connection is adopted between the link panel 13 and the push rod 221 of the leveling part 2 at this time, the push rod 221 and the cylinder body 223 will be tilted under the action of the mass of the circuit breaker itself, that is, the center axis of the push rod 221 and the center axis of the cylinder body 223 are in a non-collinear state. When leveling is performed in this state, the friction between the push rod 221 and the cylinder body 223 will increase, thereby reducing the service life of the leveling assembly 2 at this time. On the contrary, using a flexible hinge or a ball-and-spherical shaft connection can ensure that the central axis between the push rod 221 and the cylinder body 223 remains in a collinear state when the mass of the circuit breaker itself is large.

[0062] Reference Figure 5 In one embodiment provided in the present application, a cylinder body 223 is provided on the outer wall of the push rod 221 , the push rod 221 is slidably connected to the cylinder body 223 , and the cylinder body 223 is fixedly connected to the support platform 21 .

[0063] Preferably, a motor drive assembly 224 is provided outside the cylinder block 223. The motor drive assembly 224 is in transmission connection with the push rod 221. By starting the motor drive assembly 224, the push rod 221 is driven to move up and down.

[0064] It should be noted that the click drive assembly 224 can also be replaced by a hydraulic drive assembly, the purpose of which is to drive the push rod 221 to move up and down to achieve the leveling of the receiving panel 11.

[0065] Refer to Figure 1 , in an embodiment provided by the present application, the stabilizing assembly 3 includes a clamp 31 movably arranged on the end face of the receiving panel 11; a locking assembly 4 arranged between the receiving panel 11 and the accommodating panel 12; an industrial camera 5 arranged below the locking assembly 4 and connected to the connecting panel 13 for monitoring whether the locking assembly 4 is locked; a horizontal angle sensor 6 arranged above the accommodating panel 12 and penetrating through the receiving panel 11; an operation panel 7 arranged between the connecting panel 13 and the support table 21; a receiving box 8 arranged on the outer wall of the support table 21; and a moving assembly 9 arranged at the bottom of the receiving box 8 for moving the transfer trolley.

[0066] It should be noted that two groups of clamping plates 31 are symmetrically arranged. The locking assembly 4 is used to move the transfer trolley close to the circuit breaker, so that the circuit breaker can be stably locked above the receiving panel 11 of the transfer trolley; through holes are formed in the receiving panel 11 for the installation of the horizontal angle sensor 6, so that the horizontal angle sensor 6 can accurately obtain the horizontal state of the circuit breaker at this time; the operation panel 7 adopts a plastic shell, and a device operation system and control components are arranged inside. Through wireless connection, it can be touch-operated to complete the horizontal adjustment of the device's horizontal, vertical, moving mechanisms and four positions; the moving assembly 9 includes four universal wheels connected to the bottom of the receiving box 8 for moving the transfer trolley.

[0067] Refer to Figure 1 , in an embodiment provided by the present application, a first chute 111 and a second chute 112 penetrating through the receiving panel 11 are formed on the end face of the receiving panel 11.

[0068] It should be noted that at this time, the first chute 111 and the second chute 112 penetrate through the receiving panel 11 and are connected to the accommodating panel 12.

[0069] Refer to Figure 6 , in an embodiment provided by the present application, a push block 32 is fixedly arranged at the bottom of the clamp 31. A second push rod 33 is arranged at one end of the push block 32 away from the clamp 31. One end of the second push rod 33 is in transmission connection with a first drive motor 34;

[0070] Among them, the push block 32 is slidably arranged in the second chute 112.

[0071] It should be noted that the first drive motor 34 is in transmission connection with the second push rod 33. When the first drive motor 34 is started, it can drive the fixture 31 to move to adapt to circuit breakers of different sizes, so that the circuit breaker is stably placed above the receiving panel 11.

[0072] Furthermore, Figure 6 There are two sets of the fixture 31 and the transmission components driving the fixture 31, which are respectively arranged on both sides of the receiving panel 11.

[0073] Referring to Figures 7 to 8 , at this time, a second connecting block 36 is also fixedly connected to the bottom of the fixture 31. A fourth slideway 35 is slidably connected inside the second connecting block 136. The bottom of the fourth slideway 35 is fixedly connected to the end face of the receiving panel 12, and the above components are all located inside the first chute 111. When the fixture 31 moves under the action of the first drive motor 34 at this time, it also drives the second connecting block 136 to slide in the fourth slideway 35, further enhancing the stability of the fixture 31.

[0074] Referring to Figure 6 , a connecting block 132 is also fixedly connected to the bottom of the receiving panel 12. The connecting block 132 is in transmission connection with the third slideway 132 below it. The third slideway 132 is fixedly connected to the link panel 13. A transmission mechanism is connected to the outside of the connecting block 132. The transmission mechanism drives the connecting block 132 to slide on the third slideway 132, adjusts the positions of the receiving panel 11 and the receiving panel 12 at this time to move them towards the circuit breaker side, and better takes out the circuit breaker.

[0075] Referring to Figures 9 to 10 , in an embodiment provided by the present application, the locking assembly 4 includes a lock 41, a mounting block 42 provided at the bottom of the lock 41, a first slideway 43 fixedly provided on the receiving panel 12 and slidably connected to the mounting block 42, and a second drive motor 44 in transmission connection with the mounting block 42.

[0076] Starting the second drive motor 44 drives the mounting block 42 to slide on the first slideway 43, and then drives the lock 41 to slide horizontally, so that the lock 41 can adapt to circuit breakers at different clamping positions. The lock 41 is a spring lock. Through the performance of the spring, the buckle can be firmly stuck in the card slot without deviation, ensuring safety performance.

[0077] Referring to Figure 11 , in an embodiment provided by the present application, a lifting member 81 for driving the leveling assembly 2 to lift is provided in the receiving box 8.

[0078] The lifting member 81 includes a first connecting rod 812 and a second connecting rod 813, wherein the first connecting rod 812 and the second connecting rod 813 are rotatably connected, and the rotation connection position is located in the middle positions of the first connecting rod 812 and the second connecting rod 913. One end of the first connecting rod 812 is slidably connected to the support platform 21, and the other end is rotatably connected to the bottom of the accommodating box 8. One end of the second connecting rod 813 is slidably connected to the support platform 21, and the other end is rotatably connected to the bottom of the accommodating box 8. The lifting member 81 further includes an electric cylinder 811. One end of the push rod of the electric cylinder 811 is connected to the second connecting rod 813, and the other end is connected to the inside of the support platform 21. Starting the electric cylinder 811 causes the sliding parts of the first connecting rod 812 and the second connecting rod 813 to slide, driving the support platform 21 to rise or fall to adapt to the circuit breakers at different height positions.

[0079] Finally, it should be noted that the methods and devices described in detail above are only examples, and those skilled in the art can modify these examples in different ways as long as they do not depart from the scope of the present invention.
