Description
Technical Field
[0001] This utility model relates to the field of power equipment technology, and in particular to a portable electric lifting device in conjunction with a mobile platform. Background Technology
[0002] Currently, high-altitude electric lifting devices are gradually being used in the daily maintenance of power transmission networks. After using this device, most maintenance positions can be fixed-point. However, for some long spans (rivers, deep ditches, highways, canyons, dense forests, etc.), it is still necessary to select a low point above the ground to send workers to the high altitude. For conductors with four or more splits, it is necessary to walk along the line to the maintenance position. For single or double split conductors, it is necessary to use rope ladders or gantry cranes to move to the maintenance position. At this time, it is necessary to give full play to the individual's skill level and add extra physical burden to the high-altitude maintenance personnel, thus failing to maximize the role of the high-altitude lifting device.
[0003] Therefore, there is an urgent need for a portable electric lifting device to work with a mobile platform. After the electric lifting device rises to the end of the guide wire, it can move left and right at high altitudes with the help of mobile accessories, without requiring workers to carry rope ladders or fly cars. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a portable electric lifting device that works with a mobile platform. After the electric lifting device rises to the end of the guide wire, it can move left and right at high altitudes with the help of the mobile accessories, without the need for operators to carry rope ladders or gantry cranes.

[0030] Reference Figures 1 to 8 A portable electric lifting device with a mobile platform includes: a pulley connecting frame 1, a drive wheel 18 and an auxiliary wheel 16 respectively disposed at both ends of the pulley connecting frame 1, an upper connecting frame 27 disposed between the drive wheel 18 and the auxiliary wheel 16, an auxiliary rod 13 detachably connected to the bottom of the upper connecting frame 27, a handle 7 fixed to one side of the upper connecting frame 27, and a braking device between the drive wheel 18 and the auxiliary wheel 16; the drive wheel 18 and the auxiliary wheel 16 are rotatably connected to the pulley connecting frame 1, the top of the upper connecting frame 27 is fixedly connected to the pulley connecting frame 1, and the braking device is... The pulley connecting frame 1 is fixedly connected. The upper connecting frame 27, on the side away from the handle 7, houses the battery 24, circuit board 25, and driver 26. The driver 26 has a sliding control button 3. The circuit board 25 is electrically connected to both the battery 24 and the driver 26. The drive wheel 18 is electrically connected to the driver 26. The pulley connecting frame 1 is the main support for fixing two sets of pulleys. It moves on the guide wire 2 via the auxiliary wheel 16 and the drive wheel 18. The drive wheel 18 is powered by the battery 24, and the driver 26 drives the hub motor to move the device laterally on the guide wire 2. The sliding control button 3 controls the drive wheel 18 to move forward and backward on the guide wire 2.
[0031] Please refer to Figure 6 and Figure 7The braking device includes: a brake clamp fixing sleeve 29 fixedly connected to the pulley connecting frame 1, and a brake clamp 23 rotatably connected to the brake clamp fixing sleeve 29. The brake clamp 23 includes two Z-shaped clamping blocks, which are hinged in the middle. A first spring 22 is provided between the lower clamping parts of the two Z-shaped clamping blocks. The top of the two Z-shaped clamping blocks extends through the brake clamp fixing sleeve 29. The upper end of the left Z-shaped clamping block is fixedly connected to the brake line 20, and the upper end of the right Z-shaped clamping block is slidably connected to the brake line 20. The unused end of the brake line 20 extends through the upper connecting frame 27 and is slidably connected to the lifting lug 31. A brake ring 4 is provided at the end of the brake line 20. A second spring 28 is provided between the brake ring 4 and the lifting lug 31. The bottom of the two Z-shaped clamping blocks of the brake clamp 23 is opened by the first spring 22 in the natural state. When the brake ring 4 is pulled, the bottom of the two Z-shaped clamping blocks of the brake clamp 23 closes, which is the braking state. One end of the brake clamp fixing sleeve 29 is fixed to the upper connecting frame 27 and connected to the brake clamp 23 through the shaft pin 21. When no braking force is applied, the spring keeps the brake clamp 23 in a naturally open state, thus preventing the brake clamp 23 from contacting the wire 2 and ensuring the device is in a non-braking state. When the operator pulls the brake ring 4, the brake cable 20 transmits the tension through the hole at the top of the brake clamp 23. With the pulling force, the brake clamp 23 closes and clamps like scissors, generating friction. At this time, the brake clamp 23 contacts the wire 2, effectively generating sufficient friction to achieve the braking function, slowing down the movement of the device. The brake clamp 23 can open and close quickly, exhibiting high stability and allowing for timely braking as needed during device operation, improving the device's safety and operability. The driver 26 receives control signals and converts them into drive commands for the electric motor, controlling the device's movement. The battery 24 provides the necessary electrical energy to ensure normal operation even without an external power source. The circuit board 25 serves as the control center.

The driving wheel 18 and the auxiliary wheel 16 are rotatably connected to an inverted U-shaped frame respectively. The auxiliary wheel 16 is connected to the bottom of the inverted U-shaped frame with a safety pin 17 to prevent the device from falling off the wire 2.

[0036] Please refer to Figure 3 Preferably, in this embodiment, the lower end of the auxiliary rod 13 is designed with a rope hole 30 and a foot pedal 9. The auxiliary rod 13 has several adjustment holes 14, and a seat plate 8 is detachably connected to each adjustment hole 14. The lower end of the auxiliary rod 13 has a rope hole 30 and a foot pedal 9. If the electric drive part of the device fails, an insulating rope can be attached through the rope hole 30, allowing a ground worker to pull the device. The worker can sit on the seat plate 8 and place their feet on the foot pedal. The auxiliary rod 13 and the seat plate 8 are designed with a mortise and tenon structure, and can be snapped together and reinforced with a wing nut 6.
[0037] The upper connecting frame 27 is also equipped with a handle 7 on its side. When the operator is on the seat plate 8, he / she can hold the handle 7 and step on the foot pedal 9, which is ergonomic. The bottom of the foot pedal 9 is also equipped with a support sheet metal 15 to ensure the operator's comfort during operation. The auxiliary wheel 16 and the drive wheel 18 move on the conductor 2 to carry the seat plate 8 at the lower end of the auxiliary rod 13 back and forth on the conductor 2. The operator can sit on the seat plate 8 and move back and forth with the device, which facilitates the operator's daily maintenance work on the power transmission line.
[0038] Preferably, in this embodiment, the brake clamp retaining sleeve 29 is connected to the brake clamp 23 via a pin 21.
[0039] Preferably, in this embodiment, the upper end of the left Z-shaped clamp is fixedly connected to the brake line 20 via a bushing 19.
[0040] Preferably, in this embodiment, the brake line 20 is fitted with a leather layer on the brake clamp fixing sleeve 29 and the lifting lug 31 section. Example 2
