Fluid canned crane tube automatic alignment device

Abstract

The invention discloses a fluid canning crane pipe automatic-alignment device which comprises a truss, a joist barrow provided with walking wheels and a controller. A power output device installed on the joist barrow drives the walking wheels to rotate, accordingly the walking wheels correspondingly drive the joist barrow to move on the truss along a two-dimensional coordinate plane, and a vertical pipe is installed on the joist barrow. A rotary encoder for detecting the rotation speed and turning directions of the walking wheels and a non-contact scanning range finder for scanning the top of a vehicle-mounted tank body are further installed on the joist barrow. The controller, the rotary encoder, the non-contact scanning range finder, the power output device, the joist barrow and the like are matched and connected to form a closed loop feedback control system. The fluid canning crane pipe automatic-alignment device enables the vertical pipe to be automatically aligned to a tank opening formed in the top of a tank car and is high in working efficiency, manual operation intensity is greatly reduced, a manual misoperation link is thoroughly avoided, and working error rate does not exist basically.

Description

technical field [0001] The invention relates to fluid loading and unloading equipment, which belongs to the electromechanical integrated automatic control equipment for automatically aligning a crane tube with a tank mouth, in particular to an automatic positioning device for a fluid tank crane tube. Background technique [0002] Ordinary truss top canning equipment (crane tube) mainly includes the main parts such as the driving mechanism, truss car, truss, canning pipe, etc. Its working principle is: after the tank car is parked in place, the manual reversing valve for alignment is manually operated , the driving mechanism drives the truss truck to travel on the truss to drive the canned pipe (vertical pipe) to be transferred to the top of the tank mouth, and then manually operate the manual reversing valve to lower the canned pipe (vertical pipe) to the designated position. Start liquid injection, after liquid injection is finished, manually operate the manual reversing va...

AI Technical Summary

Problems solved by technology

However, some problems exist in the common truss-type top canning equipment (crane tube): ①Low work efficiency - when canning, it is necessary to manually align each vertical pipe and the mouth of the tank in sequence, and insert the canning pipe (vertical pipe) The whole process takes a long time and the work efficiency is low; ②High work intensity—for example, if it is filled by a car, the operator needs to board each filling platform one by one to operate; For train canning, the operator needs to operate each canning equipment one by one along the canning platform of tens of meters or even hundreds of meters long. When the number of equipment is large, the operator's work intensity will be very high; ③ work error High rate—Manual operation inevitably has factors such as fatigue and lack of concentration of the operator, which cause serious operational process problems such as inaccurate alignment between the vertical pipe and the tank mouth, inadequate lifting and lowering, and forgetting other safe operation links.
