Abstract

The utility model discloses an elastic locating clamping mechanism of a steel rail detection trolley. The elastic locating clamping mechanism is mainly composed of fixed side devices, movable side devices and a spring, wherein the fixed side devices are fixedly installed on the lower side of a chassis transverse beam through bolts, the movable side devices are installed on the outer side of the chassis transverse beam, one end of the spring is connected with the movable side of a locating clamping device, and the other end of the spring is connected with the chassis transverse beam. The elastic locating clamping mechanism is applied to the railway steel rail inner contour detection trolley, is used for achieving measurement on the condition that the gauge variation range is relatively large, and has the advantages of being high in clamping force, high in locating accuracy, wide in application range, and strong in reliability.

Description

A kind of rail detects dolly elasticity positioning and clamping mechanism
Technical field
The utility model relates to the positioning clamping device of the construction of railways equipment track detection car that the profile space is detected in a kind of rail, specifically be a kind of requirement of detection can satisfy gauge and change greatly the time, and can be implemented in the positioning clamping device of the detection dolly of continuous walking under the promotion of manpower.
Background technology
Train bumps between wheel and the rail when operation unavoidably, and wearing and tearing and the distortion, especially the rail medial surface that cause rail to occur in various degree are out of shape comparatively serious.Therefore, irregularly the inboard profile of rail is detected, number of contours strong point in gathering simulates contour pattern at related software, compares with standard rail profile, can well present the degree of wear of existing rail.For the timely maintenance of railway track provides foundation with changing to repair, stationarity and the safety of train operation have been guaranteed.Simultaneously also for further research rail wear and research wheel rail relation provide strong actual foundation.When the wide dolly that detects is when rail moves in the mobile steel rail, clamping and positioning device must tightly be fitted with the medial surface of two strands of rail, and it is vertical with the rail transversal surface could to guarantee to test the dolly vehicle body, the assurance precision of test result.Yet under actual conditions, the gauge variation range of two strands of rail is bigger, and general test dolly is difficult to satisfy the surveying work when gauge changes greatly.
The utility model content
Above shortcoming in view of prior art, the purpose of this utility model provides a kind of positioning clamping device that is installed on the rail detection dolly, make it to overcome the deficiency of prior art, realize that the test dolly satisfies the requirement that different gauges change, and reaches the purpose of continuous gauging.
The utility model is to realize like this, a kind of rail detects dolly chassis elasticity positioning and clamping mechanism, be installed in the rail profile space and detect and finish clamping task in location on the dolly chassis, four jiaos of rectangle chassis that detect dolly at rail are symmetrical arranged fixation side device 200 and mobile side device 300 in twos; Described fixation side device has a reaction plate 280, vertically is provided with the location steamboat that two energy roll along the rail medial surface on this reaction plate; Described mobile side device is installed in the dolly chassis crossbeam outside, comprise slide plate with three chutes, be connected with slide plate and vertically arranged link plate and two steamboats that vertically are arranged on link plate with it, all be nested with in three chutes on the described slide plate on the bolt shank that is connected with dolly chassis; One end of holddown spring is connected with slide plate, and the other end links to each other with dolly chassis.
Adopt the rail of the utility model structure to detect dolly elasticity positioning clamping device, utilize the flexible principle of extension spring, not only can make fixation side device and mobile side device and rail inboard tightly fit; And adjustable extent is big, the requirement of dolly continuous gauging in the time of satisfying gauge and change greatly.
The beneficial effects of the utility model are: the utility model rail detects dolly elasticity positioning clamping device and has that gripping power is big, accuracy of positioning is high, Applicable scope is wider, the advantage of good reliability.
Description of drawings
Fig. 1 is that rail detects dolly elasticity positioning clamping device scheme of installation
Fig. 2 is positioning clamping device fixation side structural representation
Fig. 3 is that positioning clamping device moves the side scheme of installation
Among the figure: 001, rail; 002 rail; 110 cross member of framees, 120 frame chassis; 200 fixation side devices; 210 insulation spacers; 220 bolsters; 230 location steamboats; 300 move the side device, 310 insulation spacers; 320 slide blocks; 330 steamboats, 340 slide plates; 350 chutes, 400 springs.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
Can be seen that by Fig. 1 Fig. 1 is that rail detects dolly elasticity positioning clamping device scheme of installation, rail detects dolly elasticity positioning clamping device and mainly is made up of fixation side device 200 and mobile side device 300 and corresponding spring 400.Wherein the reaction plate 280 usefulness bolts of two cover fixation side devices 200 are fixedly mounted on the vehicle frame downside respectively, the mobile side device 300 of two covers is to be installed in the cross member of frame outside respectively, one end of spring 400 connects with corresponding mobile side device 300, and its other end links to each other with corresponding cross member of frame.
The structure of fixation side device 200 as shown in Figure 2, have a reaction plate 280 on described every cover fixation side device 200, this reaction plate vertically is provided with the location steamboat 230 that two energy roll and tightly fit with the rail medial surface all the time along the rail medial surface by bolster 220.Fixation side device 200 is provided with insulation spacer 210.Be accompanied by the reach of dolly, two location steamboats 230 on this device roll along the rail medial surface, and tightly fit with the rail medial surface all the time, its objective is the location benchmark as fixation side.The purpose of insulation spacer 210 is that it can prevent that two strands of static on the rail from communicating with fixation side device 200 and whole vehicle frame insulation, damages the test dolly.
The structure of mobile side device 300 as shown in Figure 3, the mobile side device 300 of described every cover has a slide plate 340 and two mobile side steamboats 330, have three chutes 350 on the slide plate 340, all be nested with in three chutes on the bolt shank 320 that is connected with cross member of frame, wherein mobile side steamboat 330 is tightly fitted with corresponding rail medial surface.Also be provided with insulation spacer 310 on the mobile side device 300.Wherein insulation spacer prevents that with mobile side device 300 and whole vehicle frame insulation two strands of static on the rail from communicating, and damages the test dolly.
One end of spring 400 is connected with slide plate, and the other end links to each other with dolly chassis.Under the tension force effect of spring 400, mobile side device 300 can slide along the slide block 320 that is fixed on cross member of frame, guarantees that mobile side steamboat 330 tightly fits with the rail medial surface, plays the elasticity positioning action of mobile side.Enough under the big situation, it is vertical with the rail transversal surface to guarantee to detect dolly chassis at spring 400 tension force, and this accuracy for result of a measurement provides guarantee.
