Description

A kind of bridge detects Operation Van's walking and drives and bearing set

Technical field

The present invention relates to a kind of walking and drive bearing set, especially a kind of bridge that is applicable to detects the device of walking driving with the supporting of Operation Van.

Background technology

Bridge detects Operation Van to carry out that bridge detects, in the process of work such as maintenance and reinforcings, must have supporting leg to guarantee the stability and security property of complete machine, and need the realization complete machine along bridge longitudinally straight line move.At present; Bridge detects the problem that mainly there are following several respects in support leg device that Operation Van adopted: the one, be used for the locking poor performance of the oil cylinder of retractable supporting leg, the not enough dangerous phenomenon of bearing force when falling operation voluntarily because of deadweight and vibration when being easy to walk; The 2nd, do not have from walking driving function, make the telephone-moving that detects in the operation process very inconvenient; The 3rd, the selection of the parts that contact with ground is unreasonable, and load-carrying capacity is weak, wear no resistance; The 4th, structure design is not considered the tribology requirement, and dust be prone to get into friction pair such as its bearing and influences service life and reliability of service.

Summary of the invention

The objective of the invention is to overcome the weak point in the prior art, provide a kind of not only can rise the supporting stabilization, but also can drive the car load walking, simple in structure, use the bridge reliable, that the life-span is long to detect Operation Van's walking to drive and bearing set.

For realizing above-mentioned purpose; Bridge of the present invention detects Operation Van's walking and drives and bearing set; Comprise the flute profile wheel carrier, be located at the bearing support that flute profile wheel carrier both sides were taken turns, were hinged on to the interior double base of flute profile wheel carrier; Be hinged with support hydraulic oil cylinder connected to ground on the bearing support; The said double base wheel that is located in the flute profile wheel carrier is divided into driving wheel assembly and flower wheel assembly, and the driving wheel assembly places the left side in the flute profile wheel carrier, and it comprises drive hubs, driving wheel cover, minor axis, end cap, planet wheel decelerator and HM Hydraulic Motor; End cap passes through screw retention on the rear quarter panel of wheel carrier; One end journal of minor axis and the central through hole transition fit of end cap, an end of drive hubs is bearing in through bearing on the axle journal of minor axis, and the other end is connected with planet wheel decelerator through screw; The driving wheel cover is enclosed within on the outer round surface of drive hubs; Planet wheel decelerator places drive hubs inner, the axle Joint of its power input part and HM Hydraulic Motor, and its power output part is through the internal flange Joint of screw and drive hubs; On the front side plate of wheel carrier, HM Hydraulic Motor is connected with motor control valve to the housing of HM Hydraulic Motor by the road through screw retention; Described flower wheel assembly places wheel carrier in-to-in right side; It comprises driven wheel hub, follower shaft, flower wheel cover; The flower wheel cover is enclosed within on the outer round surface of flower wheel hub; Driven wheel hub is bearing on the follower shaft through two bearings, and follower shaft is fixed on the forward and backward side plate of wheel carrier through preceding axle bed and back axle bed; Described support hydraulic oil cylinder is a double acting hydraulic cylinder; The shared hinge pin of its piston rod and groove-shaped frame is hinged on the middle part of bearing support; Two hydraulic fluid ports of support hydraulic oil cylinder are connected with bidirectional hydraulic lock respectively by the road, are connected with the oil cylinder control cock through bidirectional hydraulic lock.

Described drive hubs is the cylinder of hollow; Be processed with the multiple tracks groove on the outer round surface of described drive hubs and driven wheel hub; The said flower wheel cover that is enclosed within the driving wheel cover on the drive hubs and is enclosed within on the driven wheel hub is the polyurethane cover.

Beneficial effect:, then can be bridge detection Operation Van the telephone-moving that propulsive effort is big, speed is little power is provided owing to adopt HM Hydraulic Motor and built-in planet wheel decelerator; Owing to bidirectional hydraulic lock is set on the support hydraulic oil cylinder oil circuit, can guarantee that then it carries good rigidly, stretch out the dangerous phenomenon that is caused voluntarily because of deadweight and vibration in the time of also can avoiding going; Owing to installed the groove-shaped frame of good rigidly, can further prevent the soft leg accident that causes because of support hydraulic oil cylinder, bidirectional hydraulic lock fault; Because the wheel that contacts with ground cover all adopts polyurethane material, load-carrying capacity is strong, and resistance to abrasion is good, adopts pouring technology that polyurethane wheel cover is connected with the wheel hub that external cylindrical surface has some grooves mutually simultaneously, prevents that effectively obscission from taking place.It is simple in structure, use is reliable, long service life, not only can rise the supporting stabilization, but also can be the required telephone-moving of operation propulsive effort be provided, have practicality widely.
