Abstract
The utility model relates to a mileage device for a work vehicle for railway paving, comprising a testing part and a fixing part. The testing part comprises a mileage wheel contacting with the surface of the steel rail and a signal feedback encoder; the testing part is fixed under the body of the work vehicle by the fixing part. In terms of the structure of the fixing part, a guide sleeve is mounted under a built-up beam, the upper end of the guide pillar is nested by the guide sleeve, the testing device is mounted at the lower end, a lifting oil cylinder is installed in parallel with the guide pillar, the upper end of the lifting cylinder is fixed outside of the guide sleeve, the free end is coupled with the guide pillar in a detachable manner, and the free end is fixedly coupled with the guide pillar when under hung-carriage state and separated under working state. The guide pillar is controlled by the lifting oil cylinder to make upward and downward movement, collecting and releasing can be achieved, and the working states can be switched. The mileage wheel sits on the rail surface by deadweight, and forms a kinematic pair with the guide sleeve that makes flexible vertical movements along the guide pillar. By such way, the impact of the vehicle frame and the vehicle-mounted gantry crane to the precision of the mileage is removed, the precision of the mileage is ensured and the service life of the mileage device is increased.
Description
Technical field
The utility model relates to a kind of log arrangement, particularly a kind of odometer device for laying rails work-vehicle.
Background technology
Log arrangement is mounted in that to be used for accurately measuring the unit of laying a railway track on the track laying car distance travelled, and information is sent to the device of control system.As the log arrangement that is adopted in the units of laying a railway track such as TCM60, PC-NTC type, be located at the rear of two bogies of working vehicle in the prior art, be installed on the framework by two groups of reservoirs, during work, the wheel of having the records of distance by the log is close to the rail surface and is rolled, taximeter is given several pulse signals of control device simultaneously, and pulse signal sends instruction after the control device processing makes cloth pillow mechanism and the even mechanism of resting the head on finish a working cycles.The adjustment of sleeper pitch can be set up according to number of pulses.The wheel installing rack is the oblique three-legged structure of rigidity owing to have the records of distance by the log, and does not have vertical buffer, is subjected to the impact that car body and straddle truck bring inevitably, is easy to generate the elastic deformation of direction along ng a path, influences the precision of having the records of distance by the log, and damages easily.
The utility model content
The purpose of this utility model is to provide a kind of novel odometer device for laying rails work-vehicle, and it can effectively eliminate the influence of the impact of vehicle frame and vehicle-mounted straddle truck to the precision of having the records of distance by the log, and guarantees to have the records of distance by the log accurately, prolongs the application life of log arrangement.
The technical solution of the utility model is: a kind of odometer device for laying rails work-vehicle, comprise detection part and fixed part, described detection part comprises the encoder of have the records of distance by the log wheel and the feedback signal that contact with the rail surface, described detection part is fixed under the car-body of operation car by fixed part, the structure of described fixed part is: guide pin bushing vertically is installed on to be installed under the crossbeam, and the guide pillar upper end is set in the guide pin bushing, the lower end is equipped with checkout gear.
As to further improvement of the utility model, described guide pin bushing also is provided with the hoist cylinder of guide pillar in parallel outward, and the free end of described hoist cylinder and guide pillar are for detachably to connect.
As to further improvement of the utility model, described hoist cylinder is that detachable bearing pin connects with the detachable connecting mode of guide pillar.
As to further improvement of the utility model, described guide pin bushing is fixed by two hounds.
The utility model is work like this: log arrangement is located at the rear of two bogies of working vehicle, in the time of in working order, make hoist cylinder and guide pillar be in released state, guide pillar can freely move up and down along guide pin bushing, the wheel of having the records of distance by the log rolls along the rail surface, by the pass to control device of encoder with feedback signal.When hanging the fortune state, make hoist cylinder and guide pillar be in the state of being fixedly connected, guide pillar is moved up and down by oil cylinder control, can carry out folding and unfolding, the convenient fortune of hanging.
The beneficial effects of the utility model are: the wheel of having the records of distance by the log during the utility model work is withheld in rail level by deadweight, and constitute kinematic pair by guide pillar and guide pin bushing, can be along the vertical flexible motion of guide pillar, withhold mechanism and can effectively eliminate the impact of vehicle frame and vehicle-mounted straddle truck, make it be adjacent to the rail rail level all the time and make pure rolling.When the wheel of having the records of distance by the log makes diameter less than setting value because of abrasion, change the wheel of having the records of distance by the log, avoid influencing cloth pillow precision.It can effectively eliminate the influence of the impact of vehicle frame and vehicle-mounted straddle truck to the precision of having the records of distance by the log, and guarantees to have the records of distance by the log accurately, prolongs the application life of log arrangement.Because hoist cylinder and guide pillar are detachable connecting mode, guide pillar can be moved up and down by oil cylinder control, carries out folding and unfolding, the convenient fortune of hanging.

The specific embodiment
Embodiment 1
A kind of odometer device for laying rails work-vehicle, comprise detection part and fixed part, detection part comprises the encoder of have the records of distance by the log wheel and the feedback signal that contact with the rail surface, detection part is fixed under the car-body of operation car by fixed part, the structure of fixed part is: guide pin bushing 4 vertically is installed on installs crossbeam 1 time, fixing by two hounds 2, guide pillar 5 upper ends are set in the guide pin bushing 4, the lower end is equipped with checkout gear 6, the outer hoist cylinders in parallel 3 that also are provided with of guide pin bushing 4, the free end of hoist cylinder 3 and guide pillar 5 connect for detachable bearing pin.Transfer to bearing pin during duty, make guide pillar 5 and hoist cylinder 3 be in released state, guide pillar 5 can freely move up and down along guide pin bushing 4, inserts bearing pin when hanging the fortune state, and both are fixedly connected, and guide pillar is moved up and down by oil cylinder control.
Including but not limited to above-mentioned embodiment,, promptly belong to protection domain of the present utility model for of the present utility model as long as adopted the structure that vertical buffer is set.
