Abstract
Description
Technical Field
[0001] This utility model relates to the field of power equipment installation technology, and in particular to a lifting device for power equipment installation. Background Technology
[0002] In the field of power equipment installation, efficient and safe installation tools are of paramount importance for ensuring the smooth progress of installation work and improving operational efficiency.
[0003] Currently, in many power equipment installation scenarios, it is frequently necessary to lift equipment to different heights for installation, commissioning, or maintenance. For example, when installing transformers and switchgear in a substation, different equipment may need to be installed at different heights from the ground to meet electrical safety distances, wiring requirements, etc. However, many existing lifting devices have significant shortcomings in adjusting the lifting height. Some traditional lifting devices only have a limited number of fixed lifting height settings, which cannot be flexibly adjusted according to actual precise needs. This means that during actual installation, if the required height does not exactly match the device's fixed settings, additional auxiliary measures are often required, such as adding shims, which is not only cumbersome but may also affect the stability and accuracy of equipment installation.
[0004] Meanwhile, considering the handling and installation process of electrical equipment, many pieces of equipment are placed on a trolley-shaped bottom structure during transportation to facilitate movement. However, existing lifting devices have many shortcomings in supporting and securing trolley-shaped bottoms. Some lifting devices are not specifically designed to adapt to the support structure of trolley-shaped bottoms and can only be secured by simple rope binding. This method of securing is not only ineffective but also prone to rope loosening during equipment lifting.
[0005] Therefore, a lifting device for installing power equipment is needed. Utility Model Content

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] Example 1, as Figures 1 to 7As shown, a lifting device for installing power equipment includes a trolley 1. A sliding mechanism 4 is fixedly connected to the upper rear part of the trolley 1. A guide roller 6 is fixedly connected to the upper side of the sliding mechanism 4. A locking mechanism 5 is fixedly connected to the upper side of the middle part of the sliding mechanism 4. A lifting plate 7 is slidably connected to the front end of the sliding mechanism 4. A lifting component 3 is fixedly connected to the rear end of the trolley 1. Support components 2 are fixedly connected to the inner cavities of the left and right ends of the trolley 1.
[0028] Furthermore, the lifting assembly 3 consists of a motor, a drive shaft, a reducer, a drum, and a wire rope. The end of the wire rope away from the lifting assembly 3 is wound around and connected to the outer surface of the guide roller 6 and fixedly connected to the upper rear side of the lifting plate 7.
[0029] In the specific implementation of this utility model, firstly, the entire device is moved to a suitable position using a trolley 1. Then, according to the required installation height of the electrical equipment, the external sliding mechanism 4 is taken out and vertically installed on the upper end of the sliding mechanism 4 fixed to the upper end of the trolley 1. Then, by pulling the internal structure of the locking mechanism 5, the internal structure of the locking mechanism 5 is driven to move, so that the internal structure of the locking mechanism 5 locks the sliding mechanism 4 spliced on the upper side. Then, the operator passes the wire rope down from the middle of the uppermost guide roller 6, and then fixes the end of the wire rope to the upper end of the lifting plate 7. Then, the prepared electrical equipment is placed on the upper plate 7. Then, the internal structure of the support component 2 is flipped out. The internal structure of the support component 2 ensures that the trolley 1 will not shift during the lifting process. Then, the motor inside the lifting component 3 is started to drive the drum to rotate, which pulls the wire rope to wind it up, so that the lifting plate 7 is lifted upward at the front end of the sliding mechanism 4.
[0030] Example 2: In order to achieve the purpose of splicing and adjusting the lifting height, refer to... Figure 4 and Figure 5 In this scheme, the sliding mechanism 4 includes two slide rails 41, which are fixedly connected to the left and right sides of the upper rear part of the trolley 1, respectively. A fixing rod 42 is fixedly connected to the lower side of the opposite surfaces of the two slide rails 41. A fixing plate 43 is fixedly connected to the left and right sides of the upper end of the fixing rod 42. A recessed hole 45 is opened at the upper end of the two slide rails 41.
[0031] Furthermore, each of the two slide rails 41 is equipped with another slide rail 41 at its upper end, and a pin hole 44 is provided between the lower opposing surfaces of the two upper slide rails 41.
[0032] In the above, the lower ends of the two slide rails 41 are directly engaged in the inner cavity of the lower recess 45. Then, the pin holes 44 in the inner cavity of the slide rails 41 correspond to the sliding holes opened on the upper side of the opposite surface of the pin holes 44. Then, the internal structure of the locking mechanism 5 is simultaneously inserted into the inner cavity of the two pin holes 44, so that the two pin holes 44 are fixed in the inner cavity of the lower recess 45. The sliding grooves at the front ends of several slide rails 41 are connected, so that the lifting plate 7 can be smoothly raised to the front end of the upper slide rail 41 while sliding, thereby achieving the purpose of splicing.
[0033] Specifically, in order to fix the upper pin hole 44 to the lower pin hole 44, refer to Figure 6 In this solution, the locking mechanism 5 includes a support box 51, which is fixedly connected to the upper part between the opposing surfaces of the two slide rails 41. Two guide wheels 56 are fixedly connected to the middle of the inner cavity of the support box 51. Baffles 55 are fixedly connected to the left and right sides of the middle of the inner cavity of the support box 51. Limiting cylinders 52 are fixedly connected to the left and right walls of the inner cavity of the support box 51. Pins 53 are slidably connected to the inner cavities of the two limiting cylinders 52. Springs 54 are fixedly connected to the side of the opposing surfaces of the two pins 53 away from their axis. Ropes 57 are fixedly connected to the middle of the opposing surfaces of the two pins 53. The ends of the two ropes 57 that are close to each other pass through the outer surface of the baffle 55 on the same side and are wrapped around the outer surface of the guide wheel 56 on the same side. The ends of the two ropes 57 that are close to each other pass through the bottom wall of the support box 51 and are fixedly connected to a handle 58.
[0034] Furthermore, the ends of the two pins 53 that are far apart from each other both penetrate the inner wall of the support box 51 and the outer surface of the slide rail 41 on the same side and are slidably connected to the inner cavity of the pin hole 44 on the same side.
[0035] In the above process, the operator first pulls the handle 58, causing the ropes 57 to move closer together under the action of the two guide wheels 56. This causes the two ropes 57 to pull the pins 53 closer together, so that the ends of the two pins 53 that are far apart enter the inner cavity of the limiting cylinder 52. Then, another operator engages the lower end of the upper pin hole 44 into the inner cavity of the lower recess 45, so that the pin hole 44 corresponds to the inner cavity of the limiting cylinder 52 on the same side. Then, the operator releases the handle 58, and under the action of the spring 54, the two pins 53 are pushed away from each other, so that the two pins 53 penetrate the inner wall of the support box 51 and the outer surface of the slide rail 41 and enter the inner cavity of the pin hole 44, thereby achieving the purpose of splicing and fixing the slide rail 41.
[0036] Specifically, in order to ensure that the trolley 1 does not move during the lifting of the electrical equipment, refer to Figure 2 and Figure 3In this scheme, the support component 2 includes two rotating plates 21, which are rotatably connected to the middle of the left inner cavity and the middle of the right inner cavity of the trolley 1, respectively. The upper ends of the two rotating plates 21 are provided with through holes on opposite sides. A slide cylinder 23 is slidably connected to the inner cavity of the through hole. A threaded rod 22 is threadedly connected to the inner cavity of the slide cylinder 23. The upper part of the threaded rod 22 is rotatably connected to the upper end of the rotating plate 21. A fixed plate 24 is fixedly connected to the lower end of the slide cylinder 23.
[0037] In the above process, the rotating plate 21 is first flipped outward, and then the rotating plate 22 is rotated by the turntable at the upper end of the rotating threaded rod 22. The rotation of the threaded rod 22 causes the connected slide cylinder 23 to move downward through the through hole, thereby causing the slide cylinder 23 to drive the fixed plate 24 to contact the ground, thus achieving the purpose of fixed support.
[0038] It should be noted that the specific installation method, circuit connection method, and control method of the lifting component 3 used in this utility model are all conventional designs, and will not be described in detail in this utility model.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
