Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] like figure 1 and figure 2 As shown, a structural schematic diagram of the lifting maintenance vehicle of the present invention is provided, which includes a vehicle frame 1, wheels 2, lifting winch 3, lifting hydraulic cylinder 4 and operating platform 5, and the vehicle frame 1 shown plays a role of fixing and supporting, The wheels 2 are arranged below the vehicle frame 1 , and the wheels 2 are driven to rotate by the series-excited motor 9 , and the front wheels 2 are turned under the driving action of the steering hydraulic cylinder 6 . The console 5 is fixed on the vehicle frame 1 through the lifting winch 3 , and the lifting winch 3 expands and contracts under the driving action of the lifting hydraulic cylinder 4 .

[0017] like image 3 As shown, the circuit diagram of the control system of the lifting maintenance vehicle of the pres...

Abstract

The lift maintenance vehicle control system of the present invention is characterized in that: the forward gear is connected in series with the normally closed point of relay K2 and relay K1 and then connected to both ends of the power supply; The solenoid valve is connected in series with the normally open point of the relay K10 and connected to both ends of the control power supply; after the rising jog switch is connected in series with the normally closed point of the relay K12 and the relay K11, the descending jog switch is connected with the normally closed point of the relay K11 After being connected in series with the relay K12, both ends of the control power supply are connected. The lifting maintenance vehicle control system of the present invention realizes the forward and backward movement of the maintenance vehicle through forward and reverse control of the series excitation motor; the steering function can be realized under the control of the steering hydraulic cylinder by the left and right turning solenoid valves. By setting the relays K11 and K12 connected in series with the ascending jog switch and the descending jog switch, the ascending and descending operation of the console is realized.

Description

technical field [0001] The present invention relates to a control system of a lifting maintenance vehicle, more specifically, to a control system of a lifting maintenance vehicle that can automatically advance, retreat and turn, and the operating platform can be lifted. Background technique [0002] As a special-purpose vehicle, the lifting maintenance vehicle can complete the inspection and maintenance of high-altitude equipment by standing on the operating platform. But the automatic control level of the existing lifting maintenance vehicle is relatively low, and it does not integrate the forward, backward, steering, braking and automatic lifting of the vehicle, which is very inconvenient to use. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned technical problems, the present invention provides a control system for an elevating maintenance vehicle that can automatically advance, retreat and turn, and the operating platform ...
