Description

Technical Field

[0001] This utility model relates to the field of low-voltage switchgear transfer technology, specifically a low-voltage switchgear labor-saving transfer device. Background Technology

[0002] As the name suggests, a low-voltage distribution cabinet is a power distribution device used in a power supply system for power distribution, control, metering, and cable connection. During installation, the user needs to move the low-voltage distribution cabinet to the installation location.

[0003] The existing utility model patent with publication number CN222663523U discloses a high- and low-voltage switchgear transfer device, belonging to the field of high- and low-voltage switchgear transfer technology. It includes a movable base with a support plate on top for supporting the high- and low-voltage switchgear. Lifting components for moving the support plate up and down are installed at the four corners of the bottom of the movable base. This utility model allows the support plate to be inserted into the bottom of the high- and low-voltage switchgear using the movable base, and then the switchgear is lifted by the lifting components. At this time, the user can use the first and second limiting components to limit the switchgear around its perimeter to prevent it from slipping off the top of the support plate during transfer. This device allows for relatively stable transfer of the high- and low-voltage switchgear without requiring manual handling of the switchgear onto the support plate, significantly reducing the workload of operators.

[0004] The aforementioned transfer device relies on "moving the base to drive the support plate into the bottom of the distribution cabinet" to achieve lifting, but it lacks a "guide structure". If the distance between the bottom of the distribution cabinet and the ground is small, or if there are protruding support feet or cables at the bottom of the distribution cabinet, the support plate is difficult to insert smoothly, requiring manual prying to raise the bottom of the distribution cabinet, which increases the workload. At the same time, the operation of the second limiting component requires three steps: "pulling out the pull rod → inserting the side limiting plate → tightening the locking rod", and the locking rods need to be manually rotated and tightened one by one. In addition, the installation of the detachable limiting plate requires manual alignment of the clips and slots and pressing down to fix it. If the distribution cabinet is heavy and there are no leverage points on the side, it is difficult for a single person to complete the installation of the limiting plate, requiring multiple people to cooperate, which reduces the transfer efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a low-pressure switchgear labor-saving transfer device, which solves the problems of incompatibility with different base plates and cumbersome locking operations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A low-voltage switchgear labor-saving transfer device includes a support frame, and a transfer mechanism is provided above the support frame for transferring the low-voltage switchgear. The transfer mechanism includes: The support assembly includes a directional wheel fixedly installed on the front side of the support frame, a support plate fixedly installed on the top of the support frame, a connecting shaft fixedly installed on the front side of the support frame, a connecting rod movably installed on the outer side of the connecting shaft, a caster wheel fixedly installed at the bottom end of the connecting rod, a transmission rod fixedly installed between the connecting rods, a connecting frame movably installed on the outer side of the transmission rod, a limit rod fixedly installed on one side of the support frame, and a battery fixedly installed on one side of the support frame. The transmission components are located on both sides of the support components to limit the position of the low-voltage switchgear.

[0007] Preferably, the transmission assembly includes electric actuators fixedly installed on both sides of the support frame. A guide rod is fixedly installed at the movable end of the electric actuator. A groove is provided on the surface of the guide rod. A limit block is movably installed above the groove. A limit shaft is fixedly installed at the rear end of the guide rod. A baffle is movably installed on the outer side of the limit shaft.

[0008] Preferably, the directional wheels are fixedly installed on the left and right sides of the front end of the support frame, the rear end of the support plate has an inclined structure, and the rear end of the support plate is in contact with the ground when the support frame is in a vertical state.

[0009] Preferably, the connecting rod and the connecting shaft are rotatably connected, the connecting frame and the transmission rod are rotatably connected, and one side of the connecting frame is provided with a groove structure that fits into the limiting rod.

[0010] Preferably, the electric actuators are symmetrically installed on the left and right sides of the support frame, the rear end of the guide rod is a bent structure, and the limiting block is slidably connected to the guide rod through a groove.

[0011] Preferably, the baffle is rotatably connected to the guide rod via a limiting shaft, and a chamfered structure is provided on one side of the hinge point between the baffle and the limiting shaft. One side of the baffle contacts the limiting block, and the baffle cannot rotate when it contacts the limiting block. Beneficial effects

[0012] This invention provides a labor-saving transfer device for low-voltage switchgear. Compared with the prior art, it has the following advantages: (1) The low-voltage switchgear transfer device adapts to low-voltage switchgear with different base plates through the coordinated cooperation of the transmission component and the support component. First, the electric push rod in the transmission component can drive the guide rod to move back and forth, adjusting the relative position of the baffle and the low-voltage switchgear. The baffle can rotate flexibly through the limit shaft. When the baffle rotates to be perpendicular to the guide rod, its inclined front side can push the low-voltage switchgear backward, so that the front side of the low-voltage switchgear base plate naturally rises. Regardless of the distance between the low-voltage switchgear base plate and the ground, or whether there are protruding support feet or cables on the base plate, it can create an insertion space for the support plate. Second, the rear end of the support plate of the support component is designed with a sloping structure. The sloping surface can reduce the insertion resistance. Even if there are obstacles under the base plate, it can be smoothly inserted by the sloping surface.

[0013] (2) In terms of lateral limiting, the low-voltage switchgear does not require manual pulling, inserting or tightening of components. The limiting block can be slid to release the restriction on the baffle. After the baffle rotates around the limiting axis to a vertical state, the low-voltage switchgear will naturally fit against the baffle when it tilts backward. During the retraction of the electric push rod, the guide rod and the baffle will work together to form a lateral limiting on the low-voltage switchgear, without the need for additional locking action. In terms of longitudinal fixing and device stability, the connecting frame of the support component can rotate around the transmission rod. Its groove can be fitted with the limiting rod to quickly fix the position of the connecting rod, so that the device is kept in an inclined state. The weight of the low-voltage switchgear itself will make it fit tightly against the support frame and support plate, forming longitudinal stability. There is no need for manual installation of the detachable limiting plate or tightening of the locking rod one by one. The whole process relies on the automatic extension and retraction of the electric push rod and the simple mechanical rotation and fitting action. No multiple people are needed to cooperate. One person can complete all the limiting and fixing operations, which significantly simplifies the locking process. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a low-voltage switchgear labor-saving transfer device includes a support frame 1, and a transfer mechanism 2 is provided above the support frame 1 for transferring the low-voltage switchgear. The transfer mechanism 2 includes: a support assembly 21, including a directional wheel 211 fixedly installed on the front side of the support frame 1; a support plate 212 fixedly installed on the top of the support frame 1; a connecting shaft 213 fixedly installed on the front side of the support frame 1; a connecting rod 214 movably installed on the outer side of the connecting shaft 213; a universal wheel 215 fixedly installed at the bottom end of the connecting rod 214; and a transmission rod 216 fixedly installed between the connecting rods 214 for transmission. A connecting frame 217 is movably installed on the outside of the rod 216. A limit rod 218 is fixedly installed on one side of the support frame 1. A storage battery 219 is fixedly installed on one side of the support frame 1. A directional wheel 211 is fixedly installed on the left and right sides of the front end of the support frame 1. The rear end of the support plate 212 is a sloping structure, and the rear end of the support plate 212 contacts the ground when the support frame 1 is in a vertical state. The connecting rod 214 and the connecting shaft 213 form a rotatable connection. The connecting frame 217 and the transmission rod 216 form a rotatable connection. A groove structure that fits into the limit rod 218 is provided on one side of the connecting frame 217.

[0017] Specifically, the support frame 1 can limit the position of the support plate 212. The connecting frame 217 hooks the limiting rod 218 to limit the rotation angle between the connecting rod 214 and the support frame 1. When both the directional wheel 211 and the universal wheel 215 are in contact with the ground, the support frame 1 is tilted. At the same time, due to the pressure of the low-voltage cabinet above the support frame 1, the connecting frame 217 will tightly fasten the limiting rod 218. By tilting the low-voltage cabinet, the friction between the low-voltage cabinet and the support frame 1 and the support plate 212 is increased, preventing the low-voltage cabinet from shaking during transportation. When the support frame 1 is in a vertical state, the rear end of the support plate 212 can be easily inserted into the bottom of the low-voltage cabinet to support it.

[0018] The transmission assembly 22, disposed on both sides of the support assembly 21, is used to limit the position of the low-voltage switchgear. The transmission assembly 22 includes electric push rods 221 fixedly installed on both sides of the support frame 1. A guide rod 222 is fixedly installed at the movable end of the electric push rod 221. A groove 223 is provided on the surface of the guide rod 222. A limit block 224 is movably installed above the groove 223. A limit shaft 225 is fixedly installed at the rear end of the guide rod 222. A baffle 226 is movably installed on the outer side of the limit shaft 225. Electric actuators 221 are symmetrically installed on the left and right sides of the support frame 1. The rear end of the guide rod 222 is a bent structure. The limiting block 224 is slidably connected to the guide rod 222 through the sliding groove 223. The baffle 226 is rotatably connected to the guide rod 222 through the limiting shaft 225. A chamfer structure is provided on one side of the hinge between the baffle 226 and the limiting shaft 225. One side of the baffle 226 contacts the limiting block 224, and the baffle 226 cannot rotate when it contacts the limiting block 224.

[0019] Specifically, by sliding the limiting block 224, the limiting block 224 is prevented from contacting the baffle 226, allowing the baffle 226 to rotate and adjust its position. During loading and unloading, the baffle 226 and the guide rod 222 are aligned on the same straight line, facilitating the placement of the low-voltage cabinet between the guide rods 222. Then, the electric push rod 221 extends, moving the guide rod 222 until the baffle 226 is positioned behind the low-voltage cabinet. Subsequently, the baffle 226 and the guide rod 222 are rotated to become perpendicular to each other. Since the rear end of the guide rod 222 is inclined, when the baffle 226 and the guide rod 222 are perpendicular, its front facade is inclined. The low-voltage cabinet is then tilted backward to contact the baffle 226. At this point, the front side of the low-voltage cabinet's bottom plate is raised, allowing the support plate 212 to be inserted under the low-voltage cabinet. Then, the electric push rod 221 retracts, pushing the support plate 212 under the bottom plate of the low-voltage cabinet. Finally, one side of the low-voltage cabinet contacts the support frame 1, completing the loading operation. Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0020] During operation, in the initial state, the sliding limit block 224 disengages it from the baffle 226. At this time, the baffle 226 can rotate around the limit axis 225 until it is in a straight line with the guide rod 222. After the low-voltage cabinet is placed between the two guide rods 222, the electric actuator 221 powered by the battery 219 is activated. The electric actuator 221 extends and moves the guide rod 222 to the rear of the low-voltage cabinet until the baffle 226 reaches the rear of the low-voltage cabinet. Then, the baffle 226 is rotated to make it... Rotate around the limiting axis 225 until it is perpendicular to the guide rod 222. Because the rear end of the guide rod 222 is bent, the front side of the vertical baffle 226 is tilted, pushing the low-voltage cabinet to tilt backward and contact the baffle 226. The front side of the low-voltage cabinet bottom plate then rises. Utilizing the inclined structure at the rear end of the support plate 212, align the support plate 212 with the bottom of the low-voltage cabinet bottom plate, control the electric push rod 221 to retract, and simultaneously drive the guide rod 222 back while smoothly pushing the support plate 212 into the low-voltage cabinet. Loading is completed by moving the low-voltage cabinet under the bottom plate until one side of the cabinet is in contact with the support frame 1. Then, the connecting rod 214 is rotated so that it flips downward around the connecting shaft 213. The connecting rod 214 drives the caster 215 to the ground, and simultaneously drives the transmission rod 216 to move. The connecting frame 217 on the outside of the transmission rod 216 rotates around the transmission rod 216 until the groove on one side of the connecting frame 217 is engaged with the limiting rod 218. At this time, the support frame 1 is tilted, and the directional wheel 211 and the caster 215 jointly support the device. Pushing the device can realize the transfer of the low-voltage cabinet. When unloading, first rotate the connecting frame 217 so that it is disengaged from the limiting rod 218. The connecting rod 214 flips upward around the connecting shaft 213, the caster 215 leaves the ground, the support frame 1 returns to the vertical state, the rear end of the support plate 212 is grounded, and then the sliding limiting block 224 is disengaged from the baffle 226. The baffle 226 is rotated back to be in the same straight line as the guide rod 222. The electric push rod 221 is activated to extend, and the low-voltage cabinet can be removed from the device.
