Background technology
No matter the hydraulic elevating platform of existing electrification contact network Operation Van is sleeve pipe column or scissor structure, and the chassis of lifting table all is that the base plate with welding or thread connecting mode and operation locomotive is fixed together.When the operation locomotive operation on the slope or during the turning, fuselage can tilt, lifting table also and then tilts, and will influence the operation of operating worker like this.As snow, under the adverse weather condition such as freezing, the workman can't operation.
Summary of the invention
The purpose of this utility model is intended to overcome the shortcoming of prior art, and the leveling equipment of a kind of operation vehicle for contact wire lifting table is provided.This leveling equipment can in time be adjusted lifting table when the operation locomotive tilts, and it is horizontal all the time, to guarantee the steadily operation of safety of operating personnel.
The utility model is achieved through the following technical solutions:
The leveling equipment of a kind of operation vehicle for contact wire lifting table, comprise the sleeve pipe column hydraulic elevating platform that is installed on the working rig car bottom plate, the chassis of the cover tube column of its HYDRAULIC CONTROL SYSTEM is connected with the working rig car bottom plate, top and the job platform of cover tube column is captiveed joint, it is characterized in that: the chassis of described cover tube column is by rotating shaft and locomotive base plate hinged, and below the chassis, be positioned at two the worm screw elevators of a side setting of rotating shaft by fluid motor-driven, HM Hydraulic Motor is connected with obliquity sensor module above being arranged on the chassis by control system.
Described worm screw elevator is connected with the meshing bevel gear of hand lead screw transmission.
Described locomotive base plate is provided with upper limit position switch, lower position switch.
The locking device that automatically resets that comprises hydraulic lock dead oil cylinder and approach switch is housed on the described locomotive base plate.
The utility model compared with prior art, owing to above the chassis of cover tube column obliquity sensor is set, when the operation locomotive tilts, obliquity sensor is by measuring the static weight acceleration change, and convert thereof into the inclination angle variation, measure output transducer inclination and luffing angle with respect to the horizontal plane.The subsidiary angle switch amount of sensor assembly detects output, the way of output is opened extremely electricity level, by the output of angle control 24V voltage, can in time sense the inclination angle of job platform, again by bridge circuit, amplifying circuit, filter circuit, D/A switch circuit, Deng subsequent conditioning circuit, strain signal handle is calculated and is converted into angle and exports.By negative feedback control circuit and the actuating system formed by HM Hydraulic Motor, solenoid directional control valve, worm screw elevator etc., job platform is in time adjusted to level attitude, the operation locomotive no matter on the slope or can both satisfy the needs of unwrapping wire operation on the bend, to guarantee the steadily operation of safety of workman.Because below the chassis, be provided with two worm screw elevators, and establish the emergent hand reset attachment of bevel gear, the locking device that automatically resets by HM Hydraulic Motor control, synchronous initiation in parallel, and lead limit switch, therefore, guaranteed the safety of Operation Van more.

The specific embodiment
As shown in Figure 1, 2, 3, the leveling equipment of a kind of operation vehicle for contact wire lifting table comprises: be installed in by the sleeve pipe column hydraulic elevating platform on the working rig car bottom plate 1 of wheel 15 supportings.This hydraulic elevating platform is controlled by the working rig vehicle hydraulic system, top and the job platform 4 of its cover tube column 3 is captiveed joint, the chassis 2 of cover tube column 3 is hinged by rotating shaft 5 and locomotive base plate 1, and below chassis 2, the side that is positioned at rotating shaft is provided with two worm screw elevators 7 that driven by HM Hydraulic Motor 6, HM Hydraulic Motor 6 is connected by the control system obliquity sensor module 8 top with being arranged on chassis 2.
In order to ensure the safety of Operation Van, described worm screw elevator 7 is connected with the meshing bevel gear 10 of hand leading screw 9 transmissions, becomes the emergency hand(-)drive of leveling system.When main hydraulic circuit breaks down, can platform be resetted hand emergency hand(-)drive.
In order to ensure the safety of Operation Van, described locomotive base plate 1 is provided with upper limit position switch 11, lower position switch 12.
In order to prevent that locomotive platform when walking from rocking vibrations, is equipped with the locking device that automatically resets that comprises hydraulic lock dead oil cylinder 13 and approach switch 14 on the described locomotive base plate 1.
Shown in Fig. 4 control system schematic circuit diagram, Fig. 5 actuating system schematic diagram, among the figure:
1. J+ gets signal output rising indication, and intermediate relay Z gets electric, and main contact Z connects, and the ZDT electromagnetic valve gets electric oil-feed, and indicator lamp is bright, jacking system HM Hydraulic Motor M oil-feed, and the FDT oil return is just changeed, and rises and carries out.
2. J-gets signal output decline indication, and intermediate relay F gets electric, and main contact F connects, and the FDT electromagnetic valve gets electric oil-feed, and indicator lamp is bright, the reverse oil-feed of jacking system HM Hydraulic Motor M, and ZDT oil return counter-rotating, execution descends.
