Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to a lifting device installed on a charging pile. Background Art

[0002] With the popularization of new energy vehicles, mobile charging equipment has emerged. For example, mobile charging piles continuously draw power from fixed charging piles, store energy, and then charge electric vehicles. This has transitioned from the previous car looking for a charging pile to a mobile charging pile looking for a car to charge. However, the mobile charging pile equipment currently on the market is large in size and needs to be transported by a dedicated lifting device.

[0003] For example, the patent entitled: A lifting device for a charging pile (patent application number: CN202222062085.9) discloses a lifting device for a charging pile, in which a clamping block is fixed at both ends of the clamping rod, and the area of the clamping block is larger than the cross-sectional area of the clamping rod. The two clamping blocks are respectively clamped on the side walls of the chute on both sides. By setting the clamping blocks, the contact area with the side walls of the chute is increased, thereby making the clamping effect of the clamping rod better. During the lifting process, the lifting plate is less likely to slide in the chute, but after long-term use, the clamping blocks are prone to wear, resulting in gaps between the clamping blocks and the side walls of the chute, affecting the clamping effect, and the efficiency of use needs to be improved.

[0004] Therefore, it is necessary to propose a lifting device for charging pile installation to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a lifting device for installing a charging pile, so as to solve the problem that after long-term use, the clamping block is easily worn, resulting in a gap between the clamping block and the side wall of the slide groove, affecting the clamping effect and the use efficiency needs to be improved.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lifting device for installing a charging pile, comprising a lifting beam, a sliding channel is provided in the middle of the lifting beam, the sliding channel is trapezoidal in shape, and the width of the bottom end of the sliding channel is small, and lifting components are movably provided at both ends of the sliding channel, the lifting component comprises a lifting plate, and a limiting component is provided on the side of the lifting plate, and the limiting component comprises a square cylinder, a sliding column and a spring, the square cylinder is fixedly connected to the lifting plate, the sliding column is slidably connected to the end of the square cylinder away from the lifting plate, the sliding column abuts and cooperates with the inner wall of the sliding channel, the spring is arranged inside the square cylinder, one end of the spring is fixedly connected to the inner wall of the square cylinder, and the other end of the spring is fixedly connected to the sliding column, and the lower ends of the two lifting plates are both recessed inward on the sides away from each other to form a hook.

[0007] Preferably, an oblique cutout cooperating with the inner wall of the sliding channel is formed at one end of the sliding column away from the square tube.

[0008] Preferably, the limiting components are provided in two groups, and the two groups of limiting components are respectively distributed on both sides of the lifting plate.

[0009] Preferably, a support plate is fixedly connected to the top of the side wall of the lifting plate, and the support plate is overlapped on the top of the lifting beam.

[0010] Preferably, the number of the support plates is two, and the two support plates are respectively distributed on both sides of the lifting plate.

[0011] Preferably, an anti-slip groove is provided on the lower surface of the support plate.

[0012] Preferably, a guide assembly is provided at the bottom of the support plate, and the guide assembly includes a limit plate and a guide block. The limit plate is fixedly connected to the lower surface of the support plate, and the limit plate is rectangular. The guide block is fixedly connected to the bottom of the limit plate, and the guide block is in the shape of a right-angled trapezoid, and the end away from the lifting plate is a hypotenuse.

[0013] Technical effects and advantages of this utility model:

[0014] The utility model provides a limit assembly in cooperation with the lifting plate. When lifting the mobile charging pile, the sliding column is pressed against the inner wall of the sliding channel to prevent the lifting plate from sliding back and forth on the lifting beam, thereby improving the efficiency of the lifting device. At the same time, even if the sliding column is worn, the restoring elastic force of the spring can make the sliding column extend adaptively, thereby extending the service life.

[0015] When the lifting assembly moves downward relative to the lifting beam, the two limit plates are guided by the bevel of the guide block, so that the two limit plates quickly abut against the top of the inner walls on both sides of the sliding channel, thereby preventing the lifting plates from deflecting and improving the stability of use.

[0016] When lifting the mobile charging pile, the two lifting components can extend from the inside of the mobile charging pile through two back-to-back hooks, and hook the mobile charging pile from the inside to the outside for lifting, thereby saving the space originally required for lifting on both sides of the mobile charging pile and meeting the purpose of lifting in a narrow space.

[0023] The utility model provides Figures 1 to 5 The illustrated lifting device for charging pile installation includes a lifting beam 1, which can be docked with equipment such as a crane. A sliding channel 2 is provided in the middle of the lifting beam 1. The sliding channel 2 is trapezoidal in shape and narrow at its bottom. Lifting assemblies 3 are movably mounted at both ends of the sliding channel 2. The lifting assemblies 3 include lifting plates 4. The lower ends of the two lifting plates 4, facing away from each other, are each recessed with hooks.

[0024] When lifting the mobile charging pile, the two lifting components 3 can extend from the inside of the mobile charging pile through two back-to-back hooks, and hook the mobile charging pile from the inside to the outside for lifting, thereby saving the space originally required for lifting on both sides of the mobile charging pile and meeting the purpose of lifting in a narrow space.

[0025] The device is also suitable for lifting other equipment and can be selected according to specific circumstances.

[0026] A support plate 5 is fixedly connected to the top of the side wall of the lifting plate 4. Two support plates 5 are provided. The two support plates 5 are respectively distributed on both sides of the lifting plate 4. The support plate 5 is overlapped on the top of the lifting beam 1. The lower surface of the support plate 5 is provided with an anti-slip groove 12.

[0027] The lifting plate 4 is suspended on the lifting beam 1 through the support plates 5 on both sides. The lifting position of the lifting plate 4 can be changed by sliding the support plates 5, so as to adapt to mobile charging piles of different sizes or different lifting positions; and the anti-slip groove 12 can increase the friction between the support plate 5 and the lifting beam 1, prevent random sliding, and improve the stability of lifting.

[0028] The side of the lifting plate 4 is provided with a limit assembly, which is provided in two groups. The two groups of limit assemblies are respectively distributed on both sides of the lifting plate 4. The limit assembly includes a square tube 8, a sliding post 9 and a spring 10. The square tube 8 is fixedly connected to the lifting plate 4, and the sliding post 9 is slidably connected to the end of the square tube 8 away from the lifting plate 4. The sliding post 9 abuts and cooperates with the inner wall of the sliding channel 2. The spring 10 is arranged inside the square tube 8. The spring 10 uses a model with a large elastic support force. One end of the spring 10 is fixedly connected to the inner wall of the square tube 8, and the other end of the spring 10 is fixedly connected to the sliding post 9.

[0029] An oblique cut 11 that matches the inner wall of the sliding channel 2 is formed on one end of the sliding column 9 away from the square tube 8 .

[0030] Specifically, when lifting the mobile charging pile, the gravity of the charging pile drives the lifting assembly 3 to move downward relative to the lifting beam 1, and the lifting plate 4 is suspended on the lifting beam 1 through the support plates 5 on both sides. At this time, the sliding column 9 is in contact with the inner wall of the sliding channel 2 through the oblique cut 11. Since the sliding channel 2 is trapezoidal and the width of the bottom end of the sliding channel 2 is small, the sliding column 9 is retracted into the interior of the square tube 8 and squeezes the spring 10 to contract. The return force of the spring 10 causes the sliding column 9 to squeeze and fit the inner wall of the sliding channel 2, preventing the lifting plate 4 from sliding back and forth on the lifting beam 1, thereby improving the utilization efficiency of the lifting device.

[0031] Even if the slide post 9 is worn, the restoring force of the spring 10 can make the slide post 9 extend adaptively, thereby extending the service life.

[0032] In order to improve the stability of the lifting plate 4, a guide assembly is provided at the bottom of the support plate 5, and the guide assembly includes a limit plate 6 and a guide block 7. The limit plate 6 is fixedly connected to the lower surface of the support plate 5, and the limit plate 6 is rectangular. The guide block 7 is fixedly connected to the bottom of the limit plate 6, and the guide block 7 is in the shape of a right-angled trapezoid, and the end away from the lifting plate 4 is a hypotenuse.

[0033] Specifically, when the lifting assembly 3 moves downward relative to the lifting beam 1, under the guiding action of the oblique edge of the guide block 7, the two limit plates 6 quickly abut against the top of the inner walls on both sides of the sliding channel 2, preventing the lifting plate 4 from being offset, etc., thereby improving the stability of use.
