Abstract
A manual turning device used after current failure of a loop wheel machine belongs to the field of mechanical equipment, and is placed in a turning system of the loop wheel machine; the turning system comprises a turning gearbox, a turning motor, a damper brake and a turning control valve; the turning motor is mounted on the turning gearbox; the turning control valve is fixed on the turning motor; a non-return valve is connected with a normally-closed ball valve through a hydraulic steel pipe; and the normally-closed ball valve is communicated with the control valve and the damper brake and connected with the turning control valve. After current failure, pressurization is performed immediately to open the brake of the gearbox, and pressure of the turning control valve is released, so that after the loop wheel machine returns to the stopping position, the limited space of a deck can be alleviated advantageously, collision with other equipment can be avoided, and articles that are being lifted can be turned to and put down in a specified area.
Description
Technical field
The utility model relates to the rear Manual revolving device of loop wheel machine outage, and it belongs to the mechanical equipment field.
Background technology
At present, the main flow loop wheel machine is mainly by driven by power, and after the accident outage, the loop wheel machine that loses electric power supply can only be parked in original position, and the article of handling can not be put into the designated area.Its reason is that loop wheel machine runs out of steam since the damper brake of the rotary gear box of rotary system inside is locked and the rotovalve piece in pressure be not released, so loop wheel machine is fixed any rotation can not be arranged.Based on this, need to do the improvement of rotary system, realize the revolution of the rear manually control of outage loop wheel machine.
Summary of the invention
Defective in view of the prior art existence, the purpose of this utility model provides the rear Manual revolving device of loop wheel machine outage, can inside and outside make loop wheel machine get back to stop position after the outage, can make the article of handling be turned back to the designated area and put down, realize its distinctive function.Especially be conducive to alleviate limited space, boat deck, avoid and other equipment collisions.
For achieving the above object, Manual revolving device after the technical solution loop wheel machine outage that the utility model adopts, place in the loop wheel machine rotary system, rotary system comprises rotary gear box, rotary motor, and damper brake and rotary control valve, rotary motor are installed on the rotary gear box, rotary control valve is fixed on the rotary motor, check valve is connected with normally-closed ball valve by hydraulic steel pipe, normally-closed ball valve and rotary control valve and damper brake UNICOM, and normal opening ball valve is connected with rotary control valve.Described rotary motor is HM Hydraulic Motor.Described check valve place is provided with quick coupling, and is connected force pump and connects.
Compared with prior art, the beneficial effect that the utility model has is for after cutting off the power supply, the lock of gear case is opened in pressurization rapidly, discharge rotary control valve pressure, so that after loop wheel machine gets back to stop position, be conducive to alleviate limited space, boat deck, avoid and the collision of other equipment. and can make the article of handling be turned back to the designated area to put down.
Description of drawings
Fig. 1 is the structural representation of Manual revolving device after the loop wheel machine outage.
Among the figure: 1, normal opening ball valve, 2, normally-closed ball valve, 3, rotary motor, 4, rotary gear box, 5, rotary control valve, 6, check valve, 7, damper brake.
The specific embodiment
For understanding the structure of the rear Manual revolving device of loop wheel machine outage in depth, be described as follows in conjunction with Fig. 1:
Manual revolving device after the loop wheel machine outage, place in the loop wheel machine rotary system, rotary system comprises rotary gear box 4, rotary motor 3, damper brake 7 and rotary control valve 5, rotary motor 3 is installed on the rotary gear box 4, and rotary control valve 5 is fixed on the rotary motor 3, and check valve 6 is connected with normally-closed ball valve 2 by hydraulic steel pipe, normally-closed ball valve 2 and rotary control valve 5 and damper brake 7 UNICOMs, normal opening ball valve 1 is connected with rotary control valve 5.Described rotary motor 3 is HM Hydraulic Motor.Described check valve 6 places are provided with quick coupling, and are connected force pump and connect.
After loop wheel machine ran out of steam, because the damper brake 7 of rotary gear box 4 is locked and the pressure of 5 li of rotary control valves is not released, so loop wheel machine was fixed any rotation can not be arranged.If rotation loop wheel machine, need to open normally-closed ball valve 2, close simultaneously normal opening ball valve 1, then, suppress by being connected with quick coupling with force pump, opening the lock of gear case, and, because normally-closed ball valve 2, open, so the pressure that rotary control valve is 5 li is released, at this moment, can rotate the loop wheel machine jib.
After loop wheel machine runs out of steam, rapidly the lock of gear case is opened in pressurization, discharges rotary control valve pressure, so that after loop wheel machine gets back to stop position, be conducive to alleviate limited space, boat deck, avoid and the collision of other equipment. and can make the article of handling be turned back to the designated area to put down.
