Embodiment
Fig. 1 is that hydraulic crosses obstacle ground wire running gear (calling driving in the following text), and the middle part including main wheel frame 5, the n shape main wheel frame of two secondary n shapes is provided with main axle 15 and is connected with both sides support body, and main wheel 12 is contained in (Fig. 3) on main axle by bearing 14.
In fig. 2, main wheel frame 5 upper end of two secondary n shapes is mutually affixed by head piece 7, and two main wheels 12 are also connected by connecting rod, and are arranged with brake valve 13 between two main wheels 12.
Arrange the backing pin 4 parallel with main axle in the lower end of main wheel frame 5, backing pin 4 can folding locking, to guarantee that circuit is through main wheel and backing pin.
Wheel carrier 5 lower end and seat frame 3 hinged, seat frame 3 is provided with a seat 2, and seat frame 3 bottom is connected with foot-driven lever 1.
Hydraulic climbing mechanism 8 is secured below head piece 7, hydraulic climbing mechanism 8 lower end is fixedly connected with auxiliary wheel carrier 9, jockey pulley wheel carrier 9 two ends cross out and an auxiliary wheel 11 are respectively housed, auxiliary wheel carrier is through the both sides of main wheel frame, and be provided with roller 10 and main wheel frame two side contacts, auxiliary wheel carrier can be moved up and down between main wheel frame.The ring 6 of tiing knots of whole device of being convenient to sling is set in the upper end of main wheel frame 5.
In the diagram, the structural similarity of hydraulic climbing mechanism 8 and hydraulic jack, it is made up of large tank 17, large piston 16, small oil tank 22, valve piston 21, fuel tap 24, crank 20, fuel tank 25.Large piston 16 is provided with in large tank 17, valve piston 21 is provided with in small oil tank 22, small oil tank 22 is provided with unidirectional valve 18 with the passage of large tank 17, the passage of small oil tank and fuel tank is provided with unidirectional valve 23, large tank 17 is provided with fuel tap 24 with the passage of fuel tank 25, valve piston 21 is hinged with the middle part of crank 20, and head end and the crank bearing 19 of crank are hinged, and shake crank 20 can drive valve piston to move in small oil tank.Affixed below the upper end of large piston 16 and head piece 7.Hydraulic climbing mechanism is moved up and down by large piston, whole hydraulic climbing mechanism is extended or shrinks, thus drives auxiliary wheel carrier to move up or down.
Using method:
First at each parts of ground check, confirm that hydraulic climbing mechanism 8 is the state of tightening up, the fuel tap of hydraulic climbing mechanism is closed condition.Driving winches to after on shaft tower by utilization ring 6 of tiing knots, and is opened by backing pin 4, main wheel 12 is positioned on the ground wire of transmission line, and closes backing pin 4.Maintainer is seated on seat 2, and pin is positioned on foot-driven lever 1, fastens seat belts simultaneously, and slip driving overhauls.Because seat 2 is hinged with the lower end of main wheel frame 5 by seat frame 3, after maintainer takes seat, make center of gravity lower than ground wire and naturally dangle, ensure that the safety of maintainer.
When main wheel 12 advance on ground wire encounter barrier (as stockbridge damper) time, maintainer can shake the crank 20 of hydraulic climbing mechanism 8 from small oil tank 22 to large tank 17 injection liquid force feed, large piston 16 is moved upward, because large piston 16 upper end is fixedly connected with below head piece 7, whole like this hydraulic climbing mechanism extends downwards, the auxiliary wheel carrier 9 being positioned at hydraulic climbing mechanism lower end is driven to decline, until the auxiliary wheel 11 at auxiliary wheel carrier two ends replaces main wheel stressed with ground contact.At this moment main wheel 12 raises, and gap is defined between main wheel and ground wire, when this spacing is greater than obstacle height, utilizes auxiliary wheel 11 to slide and advance, as above-mentioned spacing can continue to make hydraulic climbing mechanism increase, until this spacing is greater than obstacle height not.When the trailing wheel sliding into auxiliary wheel 11 encounters barrier (stockbridge damper), because main wheel 12 clears the jumps, maintainer opens the fuel tap 24 of hydraulic climbing mechanism 8 and connects the passage of large tank 17 and fuel tank 25, hydraulic oil in large tank is made to return fuel tank 25, large piston 16 moves downward, hydraulic climbing mechanism 8 is shunk, two main wheels 12 are allowed to contact ground wire, auxiliary wheel carrier 9 rises and gets back to initial condition simultaneously, such driving can utilize again two main wheels 12 to advance, after driving slides into maintenance station, screw brake valve 13, personnel can carry out operation.
Above-described the utility model execution mode, does not form the restriction to the utility model protection range.Any do within spirit of the present utility model and principle amendment, equivalent to replace and improvement etc., all should be included within claims of the present utility model.
