Description

Technical Field

[0001] This utility model relates to the field of busbar cable trays, and more specifically, to a flexible hoisting device suitable for busbar cable trays. Background Technology

[0002] High-quality insulation materials were used in the busbar trays, thereby improving their safety and reliability and making the entire system more complete. Busbar trays are a new type of power distribution conductor. Compared with traditional cables, they fully demonstrate their superiority in high-current transmission. Furthermore, due to the adoption of new technologies and processes, the contact resistance and temperature rise at the connection points of the busbar trunking ends and the branch line insertion points are significantly reduced.

[0003] When installing existing busbar cable trays, the busbar cable trays are generally lifted to the installation position by a lifting mechanism or manual handling. When the direction of the busbar cable tray needs to be adjusted during the installation process, multiple people or other tools are required, which is not conducive to the installation operation. Secondly, when other equipment is blocking the installation position, it is impossible to move the busbar cable tray to a suitable position. Therefore, we propose a flexible hoisting device suitable for busbar cable trays to solve the above-mentioned problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a flexible hoisting device suitable for busbar cable trays. It hooks the busbar cable trays onto installation hooks, then controls a servo motor to drive a drive shaft, causing a winding wheel to roll and reel in the flexible hoisting belt. At this time, the middle position of the flexible hoisting belt pulls the busbar cable tray to be installed upwards along the guide wheel hub until it stops at the installation position. This facilitates flexible hoisting of busbar cable trays, reduces the operational difficulty of traditional high-altitude installation of busbar cable trays, and facilitates adjusting the installation angle during installation.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A flexible hoisting device for busbar cable trays includes a placement plate, characterized in that: an electric push rod is fixedly connected to the middle position of the front side of the placement plate, and a drive seat is fixedly connected to the telescopic end of the electric push rod; two sets of symmetrical pulleys are movably connected to the bottom of the drive seat; a push frame is movably connected to the top of the drive seat near the electric push rod via a rotating shaft; and a connecting frame is movably connected to the top of the push frame via a rotating shaft.

[0009] The connecting frame is L-shaped, with connecting grooves on both sides inside the connecting frame. An adjustment mechanism is fixedly connected inside the connecting groove. A flexible hoisting mechanism is movably connected to the telescopic end of the adjustment mechanism. A rolling roller is movably connected to the rear side of the connecting frame.

[0010] Furthermore, the flexible lifting mechanism includes a servo motor, a drive shaft, a winding wheel, a guide wheel, and a flexible lifting belt. The drive shaft is fixedly connected to the output end of the servo motor. There are two sets of both the winding wheel and the guide wheel, with the guide wheels located directly in front of the winding wheel. The winding wheels are all fixedly connected to the outside of the drive shaft. One end of the flexible lifting belt is wrapped around the hub of the winding wheel, and the other end of the flexible lifting belt passes through the hub of the guide wheel and extends to its underside.

[0011] Furthermore, the drive shaft is located inside the rear side of the connecting frame, and both ends of the drive shaft are movably connected to the inside of the connecting frame through bearings. The servo motor is fixedly connected to one side of the connecting frame, and the output end of the servo motor passes through the connecting frame and is fixedly connected to one end of the drive shaft through a coupling.

[0012] Furthermore, each end of the flexible lifting belt away from the winding wheel is fixedly connected to an installation hook, and a limiting plate is fixedly connected to the outer side of the hub of the guide wheel. The limiting plate is arc-shaped, and the flexible lifting belt passes through the inner side of the limiting plate.

[0013] Furthermore, the adjustment mechanism includes a connecting rod, a fixing bar, an electric telescopic rod, and a connecting shaft. The connecting rod is symmetrically fixed to both ends of the inner side of the fixing bar, and the electric telescopic rod is located on the opposite side of the connecting rod.

[0016] 3. Beneficial Effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This solution hooks the busbar cable trays onto the installation hooks, and then controls the servo motor to drive the drive shaft to cause the winding wheel to roll and rewind the flexible lifting belt. At this time, the middle position of the flexible lifting belt pulls the busbar cable tray to be installed upward along the guide wheel hub until it stops at the installation position. This facilitates the flexible lifting of the busbar cable tray, reduces the difficulty of operation when installing the traditional busbar cable tray at a height, and makes it easier to adjust the installation angle when installing the busbar cable tray.

[0019] (2) This scheme involves pressing the placement plate against one side of the wall and controlling the retraction of the electric push rod at any time. At this time, the telescopic end of the electric push rod pulls the drive seat to move to one side of the placement plate through the pulley. At the same time, the angle between the push frame and the electric push rod gradually increases. The top of the push frame will push the connecting frame upward and move upward along the wall through the rolling roller. When the top of the connecting frame is higher than the installation position, the electric push rod is stopped. At this time, the electric telescopic rod is controlled to push the connecting shaft, so that its two ends slide on the outside of the connecting rod until the connecting shaft is located on one side of the busbar bridge installation position. This is conducive to adjusting the hoisting position according to the installation position. Secondly, the push frame, drive seat, electric push rod, placement plate and wall form a stable structure to ensure stability during hoisting. Attached Figure Description

One end of the flexible lifting belt 905 is wound around the hub of the winding wheel 903, and the other end of the flexible lifting belt 905 passes through the hub of the guide wheel 904 and extends to its underside. The drive shaft 902 is located inside the rear side of the connecting frame 6, and both ends of the drive shaft 902 are movably connected to the inside of the connecting frame 6 through bearings. The servo motor 901 is fixedly connected to one side of the connecting frame 6, and the output end of the servo motor 901 passes through the connecting frame 6 and is fixedly connected to one end of the drive shaft 902 through a coupling. The flexible lifting belt 905 is fixedly connected to the end away from the winding wheel 903 with an installation hook 10.

At the same time, the angle between the push frame 5 and the electric push rod 2 gradually increases. The top of the push frame 5 will push the connecting frame 6 upward and move upward along the wall through the rolling roller. When the top of the connecting frame 6 is higher than the installation position, the electric push rod 2 is stopped. At this time, the electric telescopic rod 803 is controlled to push the connecting shaft 804, so that its two ends slide on the outside of the connecting rod 801 until the connecting shaft 804 is located on one side of the busbar bridge installation position. This facilitates the adjustment of the hoisting position according to the installation position. In addition, the push frame 5, drive seat 3, electric push rod 2, placement plate 1 and wall form a stable structure to ensure stability during hoisting.

The top of the push frame 5 will push the connecting frame 6 upward and move upward along the wall through the rolling roller. When the top of the connecting frame 6 is higher than the installation position, the electric push rod 2 is stopped. At this time, the electric telescopic rod 803 is controlled to push the connecting shaft 804, so that its two ends slide outside the connecting rod 801 until the connecting shaft 804 is located on one side of the busbar bridge installation position. Then, the busbar bridge is hooked onto the installation hook 10. Subsequently, the servo motor 901 is controlled to drive the drive shaft 902 to cause the winding wheel 903 to roll and wind the flexible lifting belt 905. At this time, the middle position of the flexible lifting belt 905 pulls the busbar bridge to be installed upward along the hub of the guide wheel 904 until it stops at the installation position.
