The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Fig. 1, a kind of electric power climbing operation vehicle includes a traction mechanism 9 and a vehicle body 10, and a lifting base 15 and a tool box 16 are fixed inside the vehicle body 10, and the tool box 16 accommodates electric maintenance tools, and the A hydraulic telescopic mechanism 19 is provided on the lifting base 15, and a working platform 17 is provided on the top of the hydraulic telescopic mechanism 19.

Wherein, the working platform 17 is a fiberglass insulating platform, and guardrails 18 are arranged around the working platform 17. The guardrails 18 are made of insulating material, and the control buttons 20 of the hydraulic expansion mechanism are arranged on the guardrails 18. The operator stands in the guardrail 18 of the working platform 17, so the safety factor is high; at the same time, the lifting of the hydraulic telescopic mechanism 19 can be controlled by the control button 20 at high altitude without the cooperation of others.

The hydraulic telescopic mechanism 19 includes a telescopic arm with more than three sections and its hydraulic cylinder, which drives the telescopic arm to rise and fall; the number of telescopic arms and hydraulic cylinders is determined according to actual needs.

As shown in Figure 2, the hydraulic telescopic mechanism 19 includes a five-section telescopic arm, a fixed pulley 8, four steel wire ropes, two guide columns, a primary hydraulic cylinder 6 and a secondary hydraulic cylinder 7, and the five-section telescopic arm moves from bottom to top. The upper part is the first-section arm 1, the second-section arm 2, the third-section arm 3, the fourth-section arm 4 and the fifth-section arm 5; there are four fixed pulleys 8, which are arranged on the tops of the second-section arm 2 and the fourth-section arm 4 respectively. and the tail; the primary hydraulic cylinder 6 is arranged between the first-section arm 1 and the second-section arm 2, and is used to drive the second-section arm 2, and the second-section arm 2 drives the third-section arm through the fixed pulleys 8 at its top and bottom, so The above-mentioned secondary hydraulic cylinder 7 is arranged between the three-section arm 3 and the four-section arm 4, and is used to drive the four-section arm 4, and the four-section arm 4 drives the five-section arm 5 through fixed pulleys 8 at its top and bottom; the four steel wire ropes respectively It is the first steel wire rope 11, the second steel wire rope 12, the third steel wire rope 13 and the fourth steel wire rope 14. The first steel wire rope 11 goes around the fixed pulley 8 on the top of the second-section boom 2 and connects with the first-section boom 1 and the third-section boom 3 respectively. The wire rope 12 goes around the fixed pulley 8 at the bottom of the second-section boom 2 and connects with the first-section boom 1 and the third-section boom 3 respectively, and the third wire rope 13 goes around the fixed pulley 8 at the top of the four-section boom 4 and connects with the three-section boom 3 and the five-section boom 5 respectively. connected, the fourth wire rope 14 bypasses the fixed pulley 8 at the bottom of the four-section boom 4 and is connected with the three-section boom 3 and the five-section boom 5 respectively; the two guide posts are respectively the first guide post 21 and the second guide post 22, and the five-section telescopic The arms are all set on the first guide post 21 , and the four-section arm 4 and the five-section arm 5 are all set on the second guide post 22 .

The above-mentioned first-level hydraulic cylinder 6 and second-level hydraulic cylinder 7 are hollow hydraulic cylinders, the first-level hydraulic cylinder 6 is set on the first guide column 21, the second-level hydraulic cylinder 7 is set on the second guide column 22, and the first guide The column 21 and the second guide column 22 play the role of guiding and limiting the first-section arm 1 , the second-section arm 2 , the third-section arm 3 , the fourth-section arm 4 and the fifth-section arm 5 .

The working principle of the above-mentioned hydraulic telescopic mechanism 19 is that the first-section arm 1 drives the second-section arm 2 to extend and retract through the first-stage hydraulic cylinder 6, the third-section arm 3 drives the four-section arm 4 to expand and contract through the second-stage hydraulic cylinder 7, and the first steel wire rope 11 , the effect of the second steel rope 12, the third steel rope 13 and the fourth steel rope 14 is to ensure the telescopic synchronization of the two-section boom 2 to the five-section boom 5. When the secondary hydraulic cylinder 7 is stretched out, the four-section boom 4 is stretched out, and the third steel wire rope 13 and the fourth steel wire rope 14 are stressed, so that they are kept synchronous with the four-section boom 4 while lifting the five-section boom 5; Oil cylinder principle, when the extension speed of the secondary hydraulic cylinder 7 is greater than that of the primary hydraulic cylinder 6, the first steel wire rope 11, the second steel wire rope 12, the third steel wire rope 13 and the fourth steel wire rope 14 are all stressed, realizing the four-section arm 4 and the five-section boom. While the section boom 5 is decelerating, the second-section boom 2 and the third-section boom 3 are accelerated; on the contrary, when the extension speed of the second-stage hydraulic cylinder 7 is lower than the first-stage hydraulic cylinder 6, the second-section boom 2 and the third-section boom 3 are slowed down, and the speed is increased. The four-section boom 4 and the five-section boom 5 realize the synchronous extension of the two-section boom 2 to the five-section boom 5 . Similarly, when the five-section telescopic arm of the hydraulic telescopic mechanism 19 is retracted, the synchronous recovery of the two-section arm 2 to the five-section arm 5 is realized by means of the primary hydraulic cylinder 6 and the secondary hydraulic cylinder 7 . The stability of the working platform 17 is guaranteed, and the safety factor of the operators is improved.

During specific use, the required maintenance tools can be prepared in the tool box 16 in the car bucket 10 in advance, the firmness of the lifting base 15 can be checked, and the traction mechanism 9 can be used to reach the maintenance site, and the operation of ascending heights can be realized through the expansion and contraction of the hydraulic telescopic mechanism 19. One person carries out the climbing operation, and one person supervises, and only two people can complete the maintenance work. Wherein, if the height of the hydraulic telescopic mechanism 19 is too large, a hydraulic overturning mechanism can be installed between the lifting base 15 and the hydraulic telescopic mechanism 19 to place it horizontally in the vehicle bucket, and when in use, the hydraulic overturning mechanism is driven to stand it upright and then perform telescopic lifting In addition, the lifting base 15 and tool box 16 can be disassembled when not using or replacing the traction mechanism 9, and the lifting base 15 with the hydraulic telescopic mechanism 19 is installed on other facilities and can also be used.

In summary, the present invention has the advantages of compact structure, flexible and convenient operation, and can be transferred to any work site through the traction mechanism 9 as required, adapting to the characteristics of a wide distribution of power facilities, and eliminating the need to purchase additional climbing equipment, reducing the Reduce equipment costs and facilitate power maintenance work.
