AI Technical Summary

Problems solved by technology

However, there is a large vibration during the operation of the crane, which will cause some or all of the ultrasonic beams to fail to reach the surface to be tested, resulting in wrong measurement results or measurement failures.
[0016] To sum up, the existing ultrasonic ranging products using air as the medium have low precision, small range, are easily affected by occlusion and vibration, and are not suitable for measuring the walking position of cranes.

Embodiment Construction

[0032] Such as figure 1 As shown, the wheel-rail crane position detection system of the present invention includes an ultrasonic transmitter device 200 arranged at the end of the track 100 and an ultrasonic receiver device 300 arranged on the traveling mechanism.

[0033]Wherein, the ultrasonic transmitter device 200 is composed of a pressure detection device 201 , a synchronous signal generator 202 , a transmitter controller 203 and an ultrasonic transmitter 204 . The pressure detection device 201 is respectively connected to a synchronous signal generator 202 and a transmission controller 203 , and the transmission controller 203 is connected to an ultrasonic transmitter 204 .

[0034] The pressure detection device 201 is a pressure sensor or a push switch or a piezoelectric film, which is used to generate a trigger signal to trigger the ultrasonic transmitter 204 and the synchronization signal generator 202 at the same time. The ultrasonic transmitter 204 is used to emit u...

Abstract

The invention discloses a wheel track-type crane position detection system. The wheel track-type crane position detection system comprises a supersonic transmitting terminal device arranged at a track end and a supersonic receiving terminal device arranged at a travelling mechanism. The wheel track-type crane position detection system has a simple structure and a low cost, avoids a synchronizer, is not influenced by track planeness, the environment around the track, and the weather, and has strong adaptability.

Description

technical field [0001] The invention belongs to the technical field of wheel-rail cranes, in particular to a position detection system for wheel-rail cranes. Background technique [0002] Wheel-rail cranes are widely used in ports, storage yards, workshops, shipyards and other industrial occasions, such as bridge cranes and rail cranes used in container terminals, ship unloaders, stackers / reclaimers, ship loaders and doors used in bulk cargo terminals Machines, cranes used in factory workshops, gantry cranes used in shipyards, etc. Its common feature is that the whole equipment can walk along a fixed track through one or more sets of wheels. Tracks are usually two steel rails or rails mounted in parallel on a fixed foundation. The traveling wheels of the crane are in contact with the rails and are driven by motors to walk along the rails. Depending on the size of the site, the length of the track can be several kilometers. The traveling wheels on both sides of the crane ...
