Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, in particular to an electric power maintenance lifting vehicle. Background Art

[0002] The electric maintenance lift truck is a special vehicle, mainly used for high-altitude operations. It has a simple operating structure, convenient and reliable operation, and beautiful appearance.

[0003] There are two main types: articulated boom and straight boom. The articulated boom can be used for cantilevered operations, to cross certain obstacles, or to perform multi-point operations at one place. The platform has a large load capacity, can accommodate two or more people working at the same time, and can carry certain equipment. The straight boom is less restricted by space, and the working height is much higher than other types of aerial work vehicles. The height adjustment is strong, and the adjustment can be completed immediately whether it is a high floor or a low floor.

[0004] Existing electric maintenance vehicles usually rely on their own structure for lifting and lowering, and need to maintain their own balance, which limits their development. Summary of the invention

[0005] The object of the present invention is to provide an electric maintenance lift vehicle.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: an electric power maintenance lifting vehicle, including a vehicle body, a movable plate is arranged on the vehicle body to extend to both sides, and a driving mechanism for driving the movable plate to move is arranged at the inner edge of the vehicle body; a lifting mechanism is arranged on the movable plate, and the lifting mechanism includes a platform, an extension shaft is arranged on the platform, and a fixer is arranged at the end of the extension shaft.

[0007] It is further configured as follows: the fixer includes a columnar connector, and the columnar connector includes an abutment arm.

[0008] It is further configured as follows: a support plate is provided on the bottom surface of the platform, a rotating rail is provided on the peripheral wall of the platform, a rotating seat is provided on the rotating rail, and the extension shaft is provided on the rotating seat.

[0009] It is further configured as follows: the lifting mechanism includes an oblique telescopic rod and a resisting telescopic rod, the resisting telescopic rod resists below the oblique telescopic rod, and the platform is arranged at the end of the oblique telescopic rod.

[0010] In summary, the present invention has the following beneficial effects: through the electric maintenance lifting vehicle, it is possible to increase the stability of the platform by relying on power poles or small iron towers, unlike the traditional method. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0013] The present invention will be further described in detail below with reference to the accompanying drawings.

[0014] The power maintenance lifting vehicle includes a vehicle body 1. A moving plate 2 is arranged on the vehicle body 1. A driving mechanism 3 is arranged on one side of the vehicle body 1. The driving mechanism 3 drives the moving plate 2 to move to both sides through two driving motors arranged at the positions of the vehicle body 1 close to the front and rear of the vehicle head, and a rack arranged on the moving plate 2.

[0015] An inclined telescopic rod 13 is arranged on the moving plate 2 in an inclined manner to one side. A抵触 telescopic rod 14 is also arranged on the moving plate 2 and abuts against the lower part of the inclined telescopic rod 13. The inclined telescopic rod 13 and the抵触 telescopic rod 14 form an "entry" - shaped structure.

[0016] A platform 5 is arranged above the inclined telescopic rod 13. The platform 5 has a fence. The platform 5 is relatively thicker and oval - shaped compared with the traditional one. A support plate 10 is also arranged below the platform 5. A rotating track 11 is arranged on the outer peripheral wall of the platform. A number of rotating seats 12 are arranged on the rotating track 11. The rotating seats 12 move on the rotating track 11 through the driving motors arranged thereon. The support plate 10 can support the rotating seats 12. For example, a rotating wheel is arranged below the rotating seat 12 for assistance.

[0017] An extension shaft 6 is arranged on the rotating seat 12. The extension shaft 6 can be extended or retracted as needed. The extension and retraction of the extension shaft 6 are controlled by the staff on the platform 5 or the staff in the vehicle.

[0018] A fixator 7 is arranged at the end of the extension shaft 6. The fixator 7 includes a cylindrical connector 8. The cylindrical connector 8 includes a抵触 arm 9, which is used to fix the circular - cylindrical power column. The抵触 arm 9 clamps and abuts against the power column, thus ensuring the stability of the platform 5. The抵触 arm 9 includes two rotatable left and right parts, which can rotate from both sides from the outside to the inside and hold the power column under the drive of the motor, so as to achieve the purpose of fixation.

[0019] Preferably, the front end of the fixer 7 can be disassembled and replaced with another angle steel connector, which includes a contact hook body, which is fixed to a small iron tower, and the contact hook body clamps and leans against the angle steel of the iron tower, thereby ensuring the stability of the platform 5. The contact hook body also adopts a rotating method, but the difference is that it rotates from top to bottom, so as to be fixed by being placed or hooked on the angle steel of the iron tower.

[0020] Preferably, a rotatable chassis can be provided on the mobile plate 2, and the oblique telescopic rod 13 is provided on the chassis, so that the angle can be rotated, so that the vehicle body 1, the platform 5 and the fixture 7 are in a straight line and thus remain stable. The rotation of the chassis can be controlled by the staff on the platform 5.

[0021] When the present application is used, the moving plate 2 is first driven to the optimal position, and then the chassis is preferably rotated to align the approximate direction. Then the oblique telescopic rod 13 and the contact telescopic rod 14 are extended, and the platform 5 is raised. When it reaches a certain height (to prevent the vehicle body 1 from being unbalanced and tipping over), the columnar connector 8 at the front end of the extension shaft 6 is rotated through the cooperation of the rotating seat 12 and the rotating rail 11, so as to align with the position of the power column. Then the extension shaft 6 (electric push rod) is extended and close to the contact on the power column to maintain stability, and then the electric push rod is shortened during the process of continuing to rise and extend, so that the platform 5 is close to the target position to enable the staff to accurately locate the maintenance point.

[0022] After the inspection is completed, the extension shaft 6 extends while the oblique telescopic rod 13 and the abutting telescopic rod 14 retract backwards. When it reaches below a certain height, the extension shaft 6 contracts, the column connector 8 retracts and detaches from the power column, and the oblique telescopic rod 13 and the abutting telescopic rod 14 continue to contract to the shortest state, leading the movable plate 2 and the turntable to return to their original positions and be recovered, thus completing the inspection work.

[0023] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
