Abstract
The utility model discloses a displacement detection device on a crane, wherein the traveling displacement and location can be more accurate by using the displacement detection device. The displacement detection device on the crane comprises a coder, a support and a track, wherein the coder is fixed on the support; the support is provided with a mounting hole; the lower end of a rotating shaft on the coder is fixedly connected with a gear; and the gear is meshed with a rack fixed on the track. The gear on the rotating shaft is meshed with the rack on the track, so that the slip or derail phenomenon can not be caused, and furthermore, the traveling displacement and location are more accurate.
Description
Technical field
The utility model relates to displacement detector, particularly the displacement detector on hoisting crane.
Background technology
The displacement location that displacement detecting on hoisting crane mainly realizes driving a vehicle by two kinds of test format.The first is by coder, the number of turns of displacement detecting wheel walking to be calculated, and realizes the accurate location of driving walking; In operational process, de-orbiting or skidding appears in displacement detecting wheel sometimes due to driving, and the accuracy of the displacement location that causes driving a vehicle reduces.The second is by coder, the number of turns that detects the vehicle wheel walking to be counted, realize the displacement location of driving, because vehicle wheel skidding can occur in the middle of operation, make the wheel walking number of turns that detects inaccurate, the accuracy reduction of the displacement location that causes driving a vehicle.
The utility model content
The problem that the utility model solves is to provide and a kind ofly can makes the driving displacement location displacement detector on hoisting crane more accurately.
The technical solution of the utility model is to complete like this, and the displacement detector on hoisting crane includes coder, support, track, coder is fixed on support, support is provided with mounting hole, and the rotating shaft lower end on coder is fixedly connected with gear, gear and fixing tooth bar engagement in orbit.
Technique effect of the present utility model is: because the gear in rotating shaft and the tooth bar on track mesh together, can not occur skidding or derailment occurring, thereby make the driving displacement location more accurate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Describe in detail furtherly bright to the utility model by reference to the accompanying drawings, coder 1 is bolted to connection together with support 2, rotating shaft lower end on coder 1 is fixedly connected with gear 4, gear 4 meshes together with the tooth bar 5 that is welded on track 3, and support 1 is provided be used to the mounting hole that is fixed on hoisting crane.
During the driving operation, the tooth bar 5 that is welded on track 3 can not move, and gear 4 rotates, and gear 4 drives coder work.
Claims (1)
1. the displacement detector on hoisting crane, include coder, support, track, coder is fixed on support, and support is provided with mounting hole, it is characterized in that: the rotating shaft lower end on coder is fixedly connected with gear, gear and fixing tooth bar engagement in orbit.
