Background technology
A large amount of lifting operations all need be carried out in natural gas line and field, station when engineering construction, equipment installation and maintenance; As: the lifting operation of the fast opening blind of the combined filter disconnector in the field device district of standing, filter assemblies and tornadotron assembly; And these work operations points are concentrated; The operating area situation is complicated, such as: around the operating area a large amount of natural gas lines and equipment, operating area being arranged is explosion-proof district, the situation such as fuel store that construction space is narrow, do not have driving engine to use.Understand according to the applicant; At present, a natural gas line and station General Motors chassis wheel crane, its rideability, driving performance and lifting ability are superior; But its oad is big, adopt engine power, do not possess explosion-proof ability, can't satisfy the lifting operation at natural gas line and station.Therefore press for that a kind of machine shape size is little, the environmental protection of storage battery power energy-saving, easy to operate, hanging device with explosion-proof performance, to satisfy the lifting operation at natural gas line and station.
Summary of the invention
The technical matters that the present invention will solve is the defective that exists to above-mentioned prior art, proposes a kind of explosion-proof hanging device that is used for natural gas line and field, station, has explosion-proof performance, profile is small and exquisite, and is easy to operate.
The present invention is through following technical scheme technical solution problem, and a kind of electricity drives explosion-proof hanging device, comprises that a side is provided with the underframe of drive-controlling room, and drive-controlling room's side in addition is provided with handling device, and handling device is connected with the explosion-proof electrification unit with the explosive-proof hydraulic unit; Four jiaos of said underframe are provided with supporting leg, and the bottom is provided with travel driving unit; Its improvements are: be mounted with revolving bed on the said underframe; The lower end of said revolving bed constitutes revolute pair with the pivoting support that is fixed on the underframe, and the support end of arm is installed in the upper end, and the lifting end of said arm is equipped with lifting appliance.
Said underframe drive-controlling room side in addition is provided with handling device; Handling device is connected with the explosion-proof electrification unit with the explosive-proof hydraulic unit; The explosive-proof hydraulic unit comprises explosive-proof hydraulic power unit, explosion-proof solenoid valve and fuel tank, and the explosion-proof electrification unit comprises explosion-proof battery, explosion-proof electrification control box and explosive operation platform.
Said arm is formed the telescopic three sections arms of plug-in mounting in the telescopic two sections arms of plug-in mounting in said one section arm, said two sections arms by three joint arms altogether.
The lifting end of said three sections arms is equipped with the lifting appliance that is made up of pulley, steel rope and suspension hook.
The invention has the beneficial effects as follows: through improvement orthodox car chassis wheel crane; Make equipment after the improvement when possessing advantages such as driving performance, rideability and lifting ability are superior; The device proper oad is little, easy to operate, the environmental protection of storage battery power energy-saving, easy to operate, hanging device with explosion-proof performance, is applicable to the lifting operation at natural gas line and station.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is the structural representation of one embodiment of the invention.
The specific embodiment
Embodiment
The structure of present embodiment is as shown in Figure 1, and a kind of electricity drives explosion-proof crane, comprises that a side is provided with the underframe 2 of drive-controlling room 3; Four jiaos of underframe 2 are provided with supporting leg 1, and the bottom of underframe 2 is provided with travel driving unit, comprise travel steering device 7 and walking tire 9; Be mounted with revolving bed 4 on the underframe 2; The lower end of revolving bed 4 constitutes revolute pair with the pivoting support 10 that is fixed on the underframe 2, and the support end of arm 5 is installed in the upper end, and the lifting end of arm 5 is equipped with lifting appliance 6.Arm 5 contains 12, two sections arms of the telescopic two sections arms of plug-in mounting, the 12 interior telescopic three sections arms 13 of plug-in mounting in 11, one sections arms of one section arm 11.The lifting end of three sections arms 13 is equipped with the lifting appliance 6 that is made up of pulley 14, steel rope and suspension hook.Other side is provided with handling device 8 in underframe drive-controlling room; Handling device 8 connects explosive-proof hydraulic unit and explosion-proof electrification unit; The explosive-proof hydraulic unit comprises explosive-proof hydraulic power unit, explosion-proof solenoid valve and fuel tank, and the explosive-proof hydraulic power unit comprises that explosion-proof alternating current dynamo, Hydraulic Pump, motor and Hydraulic Pump are connected the drive coupling of usefulness.The explosion-proof electrification unit comprises explosion-proof battery, explosion-proof electrification control box and explosive operation platform.
During work,, hanging device is turned to and walk through handling device control travel driving unit; The control supporting leg is flexible, waits for lifting operation; Control revolving bed and arm rotate to the angle that needs, and the up-down of control arm, drive the suspension hook lifting, put down object.
