Description

Technical Field

[0001] This utility model relates to the field of engineering vehicle technology, and in particular to an insulated bucket lifting structure for a bucket truck. Background Technology

[0002] An insulated bucket truck is a special engineering vehicle designed for live-line work in power systems. It has high-level insulation performance, and its work bucket is the core working platform of the entire vehicle, which can directly carry personnel and tools to enable personnel to carry out safe work.

[0003] Existing insulated boom trucks require the bucket to support personnel and elevate them to a designated working height during operation. However, in practice, due to insufficient positioning accuracy of the bucket, operators controlling the multi-section insulated boom often need to repeatedly communicate with personnel inside the bucket and adjust its position, significantly impacting work efficiency. Furthermore, the small space and fixed layout of the bucket limit the flexibility and convenience of operators, further affecting actual work efficiency. Therefore, designing an insulated boom truck bucket lifting structure is something we need to consider in order to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an insulated bucket lifting structure for a bucket truck. Addressing usability issues, it incorporates a lifting mechanism that allows personnel inside the bucket to directly and slightly control the height of the bucket, improving positioning and work efficiency. It also includes an expansion mechanism to increase the working space for personnel inside the bucket, enhancing flexibility and convenience during operation, thus demonstrating good practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An insulated bucket lifting structure for a bucket truck includes a bucket body; a lifting mechanism comprising a U-shaped connecting block fixedly connected to the right side of the bucket body, a motor mounted on the upper end of the U-shaped connecting block, a threaded rod rotatably connected between the inner top and inner bottom of the U-shaped connecting block, the upper end of the threaded rod penetrating the inner top of the U-shaped connecting block and fixedly connected to the output shaft of the motor, a rectangular connecting block threadedly connected to the threaded rod, the rectangular connecting block slidably connected to the inner wall of the U-shaped connecting block, and a connector fixedly connected to the right side of the rectangular connecting block; and an expansion mechanism that increases the working space for the operator.

[0007] Preferably, a guide rod is fixedly connected between the inner top and inner bottom of the rectangular connecting block, and the guide rod passes through the rectangular connecting block and is slidably connected.

[0008] Preferably, the expansion mechanism includes a movable plate disposed on the left side of the working bucket body, a U-shaped support plate fixedly connected to the right side of the movable plate, a U-shaped inner groove opened on the left side of the working bucket body, a fixing block fixedly connected to the lower end of the movable plate, and a telescopic rod installed at the lower end of the working bucket body, the telescopic end of the telescopic rod being fixedly connected to the fixing block.

[0009] Preferably, the U-shaped support plate is slidably connected to the inner wall of the U-shaped inner groove.

[0010] Preferably, the motor is a servo motor that can change the direction of rotation, and the telescopic rod is a hydraulic telescopic rod.

[0011] Preferably, two safety rings are fixedly connected to the upper end of the working bucket body, and a controller is installed on the upper end of the working bucket body.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] A lifting mechanism is installed, which drives the screw rod to rotate via a motor, causing the rectangular connecting block to move relative to the U-shaped connecting block. This allows personnel inside the working bucket to make small adjustments to the working bucket directly without needing to communicate repeatedly with other operators, effectively improving actual safety and work efficiency. An expansion mechanism is also included, which controls the telescopic rod to move the moving plate and U-shaped support plate to the left simultaneously, significantly increasing the working space for personnel inside the working bucket. This effectively improves the flexibility and convenience of safe operation, and does not occupy extra space when folded up, making it highly practical overall. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-5 An insulated bucket lifting structure for a bucket truck includes a bucket body 1. Two safety rings 13 are fixedly connected to the upper end of the bucket body 1 for connecting to the safety ropes of personnel inside the bucket body 1 to improve the safety of personnel when performing high-altitude operations. A controller 14 is installed at the upper end of the bucket body 1. The controller 14 is electrically connected to a motor 3 and a telescopic rod 12 and can control the rotation of the motor 3 and the extension and retraction of the telescopic rod 12.

[0022] The system also includes a lifting mechanism, which includes a U-shaped connecting block 2 fixedly connected to the right side of the working bucket body 1. A motor 3 is installed at the upper end of the U-shaped connecting block 2. The motor 3 is a servo motor that can change the direction of rotation. A threaded rod 4 is rotatably connected between the inner top and the inner bottom of the U-shaped connecting block 2. The upper end of the threaded rod 4 passes through the inner top of the U-shaped connecting block 2 and is fixedly connected to the output shaft of the motor 3. A rectangular connecting block 5 is threadedly connected to the threaded rod 4. The rectangular connecting block 5 is slidably connected to the inner wall of the U-shaped connecting block 2. A connector 6 is fixedly connected to the right side of the rectangular connecting block 5. The working bucket body 1 can be connected to the multi-section insulated boom of the insulated bucket truck through the connector 6. A guide rod 7 is fixedly connected between the inner top and the inner bottom of the U-shaped connecting block 2. The guide rod 7 passes through the rectangular connecting block 5 and is slidably connected.

[0023] The system also includes an expansion mechanism, which increases the working space for workers. The expansion mechanism includes a movable plate 8 located on the left side of the main body 1 of the work bucket. A U-shaped support plate 9 is fixedly connected to the right side of the movable plate 8. A U-shaped inner groove 10 is opened on the left side of the main body 1 of the work bucket. The U-shaped support plate 9 is slidably connected to the inner wall of the U-shaped inner groove 10. By controlling the U-shaped support plate 9 to move out to the left from the U-shaped inner groove 10, the range of movement of personnel in the main body 1 of the work bucket can be increased, so as to carry out more flexible, convenient and safe operations. A fixing block 11 is fixedly connected to the lower end of the movable plate 8. A telescopic rod 12 is installed at the lower end of the main body 1 of the work bucket. The telescopic rod 12 is a hydraulic telescopic rod. The telescopic end of the telescopic rod 12 is fixedly connected to the fixing block 11.

[0024] In this invention, during use, the working bucket body 1 is connected to the multi-section insulated boom of the insulated bucket truck via the connecting piece 6. The worker first enters the working bucket body 1, and then the worker inside the insulated bucket truck controls the multi-section insulated boom to raise the working bucket body 1 to the approximate working range. After the raising is completed, the worker inside the working bucket body 1 can directly control the motor 3 to drive the threaded rod 4 to rotate via the controller 14, which in turn drives the rectangular connecting block 5 and the connecting piece 6 to move relative to the U-shaped connecting block 2. During the movement, since the rectangular connecting block 5 and the connecting piece 6 are directly connected to the multi-section insulated boom and are stationary, the U-shaped connecting block 2 and the working bucket body 1 move up and down slightly in the vertical direction until the working bucket body 1 moves to the designated working height (the specific lifting and lowering can be adjusted according to the actual situation). In this way, the worker inside the working bucket body 1 can directly control the working height of the working bucket body 1 in a small manner without having to communicate repeatedly with the person controlling the multi-section insulated boom, which improves the positioning efficiency and actual safe working efficiency of the working bucket body 1.

[0025] It is worth mentioning that during safe operation, the operator can control the telescopic end of the telescopic rod 12 to extend through the controller 14, causing the fixed block 11, the movable plate 8, and the U-shaped support plate 9 to move to the left simultaneously. This temporarily increases the operator's activity space inside the main body 1 of the work bucket, improving the operator's flexibility and convenience during safe operation. Subsequently, the operator can control the fixed block 11, the movable plate 8, and the U-shaped support plate 9 to move to the right simultaneously through the telescopic rod 12, causing the U-shaped support plate 9 to retract into the U-shaped inner groove 10. The entire operation is relatively convenient and does not occupy extra space when not in use, making it highly practical.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
