Description
Technical field
The utility model relates to cable well lid lift technique field, especially a kind of cable channel cover plate crane-car.
Background technology
Along with the fast development of urban construction, for adapting to the needs of urban, power cable turns the main development direction of urban electric power rack into.Along with the large-scale construction of cable, also series of problems is created, cable body operational inspection and upkeep operation all need to open so that operation to conduit line cover plate, and current opening ways often relies on manpower mode completely, and in opening process, easily damage well lid corner angle, even manpower unstability in lifting process, causes well lid to drop and injures cable.Therefore, strengthen opening Upgrade Problem research to cable well lid (particularly heavy cement well lid), be improve cable daily attention, ensure the needs of cable security.
Because between cable use procedure center line, insulation distance is little, take up an area space little, underground laying and above space, not occupation of land face, do not affect by ambient contamination, power transmission reliability is high, disturbs the advantages such as little, be widely used in urban electricity supply network personal safety and surrounding environment, and the convenience of repairing in order to O&M, as in the process of deployment of cable, a bite cable duct can be set every hundreds of rice.The operating maintenance of cable just needs to open cable channel cover plate, and the method for current cable manhole cover lifting can not meet, and cable operating maintenance is high efficiency be require that.Learn according to market research, well lid weight is substantially at more than 100kg, and common well lid opening ways moves after using crowbar to pry open well lid, and the method is not only required great effort, also very original.When run into well lid larger heavier time, workmen can be very painstaking when promoting well lid, and Chang Yinwei limited personnel and out of reach promotes effect.
Utility model content
For the problems referred to above, the utility model aims to provide a kind of cable channel cover plate crane-car improving the O&M overhaul efficiency of cable.
For realizing this technical purpose, scheme of the present utility model is:
A kind of cable channel cover plate crane-car, comprise pushing hands, chassis, front skin wheel, rear skin wheel, suspension rod, steel wire suspension hook, Hydraulic Pump and rotary connecting device, described pushing hands is arranged on the one end on chassis, described front skin wheel and rear skin wheel are fixed by screws in the bottom on chassis, described suspension rod is arranged on chassis by rotary connecting device, and described steel wire suspension hook is connected on suspension rod, and described Hydraulic Pump one end is fixed on rotary connecting device, the other end is arranged on suspension rod, and is connected with one end of steel wire suspension hook.
As preferably, described Hydraulic Pump adopts fluid to be working medium, and is connected by oil pipe between Hydraulic Pump and HM Hydraulic Motor.
The utility model utilizes Hydraulic Pump to assemble set of device, and promoting framework can combine with cordwood system, and install, dismounting, carrying be all more convenient, structure is simple, lightweight, and hoisting capacity is large, safe and reliable, processing ease.Improve original Work tool to process cable well lid Upgrade Problem, reduce and make intensity and security risk, decrease manpower and materials loss, make cable well lid energy fast lifting, improve the O&M overhaul efficiency of cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, a kind of cable channel cover plate crane-car of the utility model embodiment, comprise pushing hands 1, chassis 2, front skin wheel 3, rear skin wheel 4, suspension rod 5, steel wire suspension hook 6, Hydraulic Pump 7 and rotary connecting device 8, described pushing hands 1 is arranged on the one end on chassis 2, described front skin wheel 3 and rear skin wheel 4 are fixed by screws in the bottom on chassis 2, described suspension rod 5 is arranged on chassis 2 by rotary connecting device 8, described steel wire suspension hook 6 is connected on suspension rod 5, described Hydraulic Pump 7 one end is fixed on rotary connecting device 8, the other end is arranged on suspension rod 5, and be connected with one end of steel wire suspension hook 6.
As preferably, described Hydraulic Pump 7 adopts fluid to be working medium, and is connected by oil pipe between Hydraulic Pump 7 and HM Hydraulic Motor.
Hydraulic efficiency pressure system of the present utility model is independently hydraulic actuator, by main frame requirement fuel feeding, and controls the direction of oil stream, pressure and flow.As long as hydraulic efficiency pressure system be connected with the actuating unit one oil cylinder oil pipe on main frame, hydraulic machinery can realize the action of various regulation, carries out working cycle.The principle of work of Hydraulic Pump 7 can divide Four processes: (1) topping up: when starting working, fluid is pressed into high-low-pressure non-return valve by high-low pressure plunger simultaneously, enter oil cylinder by high-low-pressure non-return valve, when pressure rises to 1Mpa, then low pressure oil to be overflow back oil storing tube from low pressure relief valve; (2) boost: on the basis of said process, high-pressure plunger works on, and pressure raises gradually, when pressure exceedes rated pressure 63Mpa, then high pressure valve is opened, and high pressure oil to overflow back oil storing tube from high pressure valve (i.e. safety valve), and pressure remains at 63Mpa; (3) work: in the course of the work, due to clutch release slave cylinder acting, pressure can reduce, so will swinging handle at any time, the operation pressure needed for maintenance, until end-of-job; (4) unload: when working complete, need pressure to reduce to zero, open unloading valve, fluid flows back to oil storing tube, completes unloaded operation.Oil-filled, boosting, working process is actually indivisible.As long as fixed handle just can complete this three processes.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
