Description

Technical Field

[0001] This utility model relates to the field of engineering power supply technology, specifically a mobile engineering power supply that is easy to move and position. Background Technology

[0002] Mobile power supplies refer to portable power equipment used at construction sites or temporary work areas. These power supplies are typically used to power various construction machinery, lighting equipment, and other electrical equipment.

[0003] In existing technologies, mobile power supplies are typically fixedly mounted on a board with casters underneath for easy movement. However, because the casters are flexible, the board cannot be positioned precisely when the power supply is moved to the desired location. Pulling on the cables connected to the power supply can easily cause the entire device to shift. Furthermore, the operator's distance from the power supply makes it difficult to stop it in time, increasing the risk of collisions and damage. Therefore, this invention proposes a mobile power supply that is easier to move and position to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a mobile engineering power supply that is easy to move and position, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile engineering power supply that is easy to move and position, comprising: a power supply box, a movable plate at the bottom of the power supply box, a universal wheel fixedly installed at the bottom of the movable plate, and a moving positioning mechanism on one side of the universal wheel.

[0006] The mobile positioning mechanism includes a limiting plate, a threaded rod rotatably sleeved on the limiting plate, a connecting sleeve threaded onto the threaded rod, connecting rods on both sides of the connecting sleeve, and a positioning plate rotatably connected to the bottom of the connecting rods.

[0007] Preferably, a mounting plate is fixedly connected to the lower surface of the power supply box, and the mounting plate and the movable plate are fixedly connected by bolts. A winding rack is provided on one side of the mounting plate.

[0008] Preferably, a pusher is provided on the other side of the mounting plate, and the bottom of the winding frame and the bottom of the pusher are both fixedly connected to the upper surface of the moving plate, and the lower surface of the moving plate is fixedly connected to the limiting plate.

[0009] Preferably, a limit bearing is fixedly installed on the top of the limit plate, and the threaded rod is rotatably sleeved inside the limit bearing on both sides. A handwheel is provided on one side of the threaded rod.

[0010] Preferably, the handwheel is fixedly connected to one end of the connecting shaft, and the other end of the connecting shaft is fixedly connected to the threaded rod, with the connecting shaft rotatably sleeved inside the support base.

[0011] Preferably, the upper surface of the support base is fixedly connected to the movable plate, a limit groove is opened at the bottom of the limiting plate, a limit block is slidably connected in the limit groove, and the limit block is fixedly connected to the side wall of the positioning plate.

[0012] Preferably, a connecting seat is fixedly connected to the upper surface of the positioning plate, and the connecting seat is rotatably connected to one end of the connecting rod through a lower pin, while the other end of the connecting rod is rotatably connected to the connecting sleeve through an upper pin.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The entire device is easily moved by the cooperation of several sets of omnidirectional wheels installed at the bottom of the movable plate. The movable positioning mechanism allows the entire device to be positioned after it has been moved to the predetermined location. The omnidirectional wheels transport the entire device to the predetermined location. The rotation of the threaded rod drives the connecting sleeve to move in opposite directions. The connecting sleeve drives one end of the connecting rod to move, thereby rotating the connecting rod. Then, the other end of the connecting rod pushes the positioning plate to move downwards in the vertical direction. The positioning plate slowly contacts the ground. The threaded rod continues to rotate until the movable plate lifts the entire device upwards, so that the omnidirectional wheels no longer contact the ground, thus fixing the entire device in place. This achieves the in-situ positioning of the power supply box, thereby avoiding the problem of the mobile power supply being damaged by collisions with other objects due to pulling on the cables.

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: a mobile engineering power supply that is easy to move and position, including: a power box 1, a movable plate 2 at the bottom of the power box 1, a universal wheel 3 fixedly installed at the bottom of the movable plate 2, a moving positioning mechanism 4 on one side of the universal wheel 3, the moving positioning mechanism 4 including a limiting plate 5, a threaded rod 6 rotatably sleeved on the limiting plate 5, a connecting sleeve 7 threadedly sleeved on the threaded rod 6, connecting rods 8 on both sides of the connecting sleeve 7, and a positioning plate 9 rotatably connected to the bottom of the connecting rod 8.

[0022] The power supply box 1 is fixedly mounted on the movable plate 2. Several sets of casters 3 installed at the bottom of the movable plate 2 facilitate the movement of the entire device. The movable positioning mechanism 4 allows the entire device to be positioned after moving to a predetermined location. The casters 3 transport the entire device to the predetermined location. The rotation of the threaded rod 6 drives the connecting sleeve 7 to move in opposite directions. The connecting sleeve 7 drives one end of the connecting rod 8 to move, causing the connecting rod 8 to rotate. The other end of the connecting rod 8 then pushes the positioning plate 9 downwards in the vertical direction. The positioning plate 9 slowly contacts the ground. The threaded rod 6 continues to rotate until the movable plate 2 lifts the entire device upwards, causing the casters 3 to no longer contact the ground, thus fixing the entire device. This achieves on-site positioning of the power supply box 1, preventing damage caused by the pulling of cables and collisions with other objects.

[0023] Example 2: Based on Example 1, a mounting plate 10 is fixedly connected to the lower surface of the power supply box 1. The mounting plate 10 and the movable plate 2 are fixedly connected by bolts. A winding frame 11 is provided on one side of the mounting plate 10. The power supply box 1 is fixedly installed on the mounting plate 10. The mounting plate 10 is installed on the movable plate 2 by bolts, which facilitates the installation and removal of the power supply box 1. A push frame 12 is provided on the other side of the mounting plate 10. The bottom of the winding frame 11 and the bottom of the push frame 12 are both fixedly connected to the upper surface of the movable plate 2. The lower surface of the movable plate 2 is fixedly connected to the limiting plate 5.

[0024] The mounting plate 10 is fixedly connected to the power supply box 1, which facilitates the installation and disassembly of the power supply box 1 by installing and removing the bolts between the mounting plate 10 and the movable plate 2, thus facilitating subsequent maintenance. At the same time, a winding frame 11 is fixedly installed on one side of the upper surface of the movable plate 2, which facilitates the winding and unwinding of the wires. A push frame 12 is fixedly connected to the other side of the upper surface of the movable plate 2, which allows the direction of the movable plate 2 to be adjusted during the transportation of the power supply box 1 by pushing the push frame 12.

[0025] Example 3: Based on Example 2, a limiting bearing 13 is fixedly installed on the top of the limiting plate 5. The threaded rod 6 is rotatably fitted into the limiting bearing 13 on both sides. A handwheel 14 is provided on one side of the threaded rod 6. The limiting bearing 13 fixedly fitted on the top of the limiting plate 5 limits the threaded rod 6, thereby facilitating its smooth rotation. The handwheel 14 is fixedly connected to one end of the connecting shaft 15, and the other end of the connecting shaft 15 is fixedly connected to the threaded rod 6. The connecting shaft 15 is rotatably fitted into the support base 16. One end of the connecting shaft 15 is fixedly connected to one end of the threaded rod 6, and the other end of the connecting shaft 15 is fixedly fitted into the handwheel 14. The upper surface of the support base 16 is fixedly connected to the moving plate 2. A limiting groove 1 is formed at the bottom of the limiting plate 5. 7. A limiting block 18 is slidably connected in the limiting groove 17. The limiting block 18 is fixedly connected to the side wall of the positioning plate 9. The support seat 16 is fixedly connected to the moving plate 2. The support seat 16 supports the connecting shaft 15, making the connecting shaft 15 more stable during rotation. The sliding cooperation between the limiting groove 17 and the limiting block 18 makes the positioning plate 9 more stable during movement, thereby improving the positioning stability of the entire device. A connecting seat 19 is fixedly connected to the upper surface of the positioning plate 9. The connecting seat 19 is rotatably connected to one end of the connecting rod 8 through the lower pin 20. The other end of the connecting rod 8 is rotatably connected to the connecting sleeve 7 through the upper pin 21. The bottom of the limiting plate 5 is farther from the ground than the height of the universal wheel 3 from the ground during travel.

[0026] After the entire device is moved to the preset position using the casters 3, the operator can brace the casters 3 with their feet to prevent the device from shifting. At this time, by synchronously rotating the handwheels 14 on both sides of the moving plate 2, the handwheels 14 drive the connecting shaft 15 to rotate. The connecting shaft 15 then drives the threaded rod 6 to rotate within the limiting plate 5. The threaded rod 6 has two threads with opposite directions of rotation. Under the driving action of the threaded rod 6, the threaded connecting sleeve 7 moves towards each other. Thus, the connecting sleeve 7, under the rotational connection of the upper pin 21, drives the connecting rod 8 to rotate. The connecting rod 8, through the rotational connection of the lower pin 20 and the connecting seat 19, drives the positioning plate 9 to move vertically downward. During the movement of the positioning plate 9... The limiting block 18 slides within the limiting groove 17. The positioning plate 9 first contacts the ground. Then, the handwheel 14 is rotated until the positioning plate 9 lifts the entire device in the opposite direction, so that the caster wheel 3 no longer contacts the ground. This completes the positioning of the entire device in place, thus avoiding the problem of the entire device moving easily when the cable connected to the power supply is pulled. Also, because the operator is far away from the power supply, it is not possible to position and stop the entire mobile power supply in time, which may cause the mobile power supply to collide with other objects and be damaged. After the power box 1 is used, the handwheel 14 is rotated in the opposite direction to make the caster wheel 3 gradually contact the ground, thus making the entire device easy to move.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
