Description

Technical Field

[0001] The invention belongs to the technical field of boom trucks, and in particular relates to a boom truck for high-voltage live-line operations. Background Art

[0002] The bucket truck is also called the insulated bucket truck. The insulated bucket truck is a special vehicle that performs equipotential operations in places with convenient transportation and complex wiring. An insulated bucket truck usually refers to a vehicle that can perform live high-altitude operations on lines greater than 10kV. Its working bucket, working arm, control oil circuit and line, as well as the bucket arm joint can meet certain insulation performance indicators and are equipped with a grounding wire.

[0003] The existing high-voltage live working bucket arm truck includes an insulated bucket arm truck body, and the inner wall of the insulated bucket arm truck body is provided with an adjusting mechanism, and the adjusting mechanism includes a stud, a first bevel gear, a second bevel gear, a vertical plate and an inclined plate. When the motor is working, it drives the second bevel gear to rotate, and the second bevel gear drives the first bevel gear to rotate. The first bevel gear drives the stud to rotate, and the stud drives the vertical plate to move, and the vertical plate drives the inclined plate to retract inwardly, and the inclined plate drives the support rod to move inwardly. After the support rod moves inwardly, it no longer occupies much space, thereby facilitating the insulated bucket arm truck body to enter some narrow spaces for work.

[0004] Existing boom trucks mainly fix their main structures by supporting rods and discs. This design is suitable for hard ground. However, when encountering soft ground, sleepers are needed to increase the contact area and improve stability. However, this method has limitations: on the one hand, the actual contact area between the sleepers and the ground is still limited; on the other hand, the bottom of the sleepers can easily sink into the soft soil, thereby reducing the connection stability between the boom truck and the soft ground.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a high-voltage live working boom truck to overcome the shortcomings in current practical applications. Summary of the invention

The quick-release column 521 can drive the two quick-release blocks 523 to rotate toward or away from each other on the fixed frame 400 by moving and cooperating with the mounting groove 522, so that the connecting blocks 525 on the two quick-release blocks 523 can quickly cooperate with the slide grooves on the support plate A or the support plate B710, and stabilize the frame 100 and the extension boom and boom frame thereon on the hard ground, providing a stable foundation for the extension of the extension boom and the rise of the boom frame, thereby improving the safety of people and objects in the boom frame.

[0052] In a preferred embodiment, the blocking plate may be in direct contact with the soft ground or in indirect contact through sleepers, so that even if the sleepers sink into the soft ground, the connection stability between the boom truck and the soft ground can be ensured.

[0053] In this embodiment, when the connecting block 525 is connected to the support plate B710, the connecting cone 730 and the reinforcement assembly 920 are initially perpendicular to the soft ground, and the support arm 300 drives the support plate B710 to move downward through the fixing frame 400 and the quick-installation mechanism 500, and the support plate B710 drives the connecting cylinder 720, the connecting cone 730, the limit drive mechanism 800 and the reinforcement mechanism 900 to move downward synchronously, so that the connecting cone 730 and the reinforcement assembly 920 can penetrate into the soft ground;

[0060] The working principle of the present invention is:

[0061] The worm 511 can drive the worm wheel 512 to rotate by rotating, and the worm wheel 512 rotates through the gear 514 of the transmission shaft 513, and the gear 514 drives the quick-loading column 521 to move through the rack 515. The quick-loading column 521 can drive the two quick-loading blocks 523 to rotate in the same direction or oppositely on the fixed frame 400 by moving and cooperating with the installation groove 522, so that the connecting blocks 525 on the two quick-loading blocks 523 can quickly cooperate with the sliding grooves on the support plate A or the support plate B710. When the quick-loading assembly 520 is connected to the support plate A, the support arm 300 can stabilize the frame 100 and the extension arm and the boom frame thereon on the hard ground by cooperating with the fixed frame 400, the quick-loading mechanism 500 and the support plate A, so as to provide a stable foundation for the extension of the extension arm and the rise of the boom frame, and improve the safety of people and objects in the boom frame;

[0062] When the connection block 525 is connected to the support plate B710, the connection cone 730 and the reinforcement plate 923 are both perpendicular to the soft ground in the initial state, reducing the resistance encountered by the reinforcement plate 923 when entering the soft ground. The support arm 300 drives the support plate B710 to move downward through the fixing frame 400 and the quick-installation mechanism 500, and the support plate B710 drives the connection cylinder 720, the connection cone 730, the limit drive mechanism 800 and the reinforcement mechanism 900 to move downward synchronously, so that the connection cone 730 and the reinforcement assembly 920 can penetrate into the soft ground.

[0063] When the blocking plate 810 contacts the soft ground and stops moving downward, the blocking plate 810 can drive the rotating column 820 and the transmission member 850 thereon to stop moving downward. At this time, the connecting cylinder 720 continues to move downward, so that the slider in the downward movement process can drive the rotating column 820 to rotate by cooperating with the spiral slideway 830 and the vertical slideway 840. The rotating column 820 drives the screw rod 911 to rotate through the transmission member 850, and the screw rod 911 drives the screw sleeve 912 to move upward in the connecting cylinder 720. When the screw sleeve 912 drives one end of the connecting rod 914 to move upward, its other end moves upward accordingly, so that the connecting rod 914 can drive the rotating block 921 to rotate in the arc groove 740, and the rotating block 921 drives the rotating block 921 perpendicular to the soft ground. The reinforcement plate 923 rotates, which not only increases the contact area between the reinforcement assembly 920 and the soft ground, thereby increasing the connection area between the support plate B710 and the soft ground, and improving the stability of the support arm 300 and the frame 100 on the soft ground, but also increases the resistance encountered by the reinforcement assembly 920 when moving upward, further improving the stability of the support arm 300 and the frame 100 on the soft ground, and improving the supporting capacity of the support arm 300 under soft ground conditions, providing a stable foundation for the extension of the extension arm and the rise of the boom frame, improving the safety of people and objects in the boom frame, and further providing a stable foundation guarantee for high-voltage live working, which significantly improves the safety during high-voltage live working;

[0064] The above is the working principle of the high-voltage live working boom truck.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
