Detailed description of the invention
Fig. 1 is that hydraulic crosses obstacle ground wire running gear (calling driving in the following text), includes the main wheel frame of two secondary n shapes
The middle part of 5, n shape main wheel framves is provided with main axle 15 and is connected with both sides support body, and main wheel 12 is contained in by bearing 14
On main axle (Fig. 3).
In fig. 2, main wheel frame 5 upper end of two secondary n shapes is fixedly connected with each other by head piece 7, two main wheels 12
Connect also by connecting rod, and be arranged with brake valve 13 between two main wheels 12.
The backing pin 4 parallel with main axle is set in the lower end of main wheel frame 5, backing pin 4 can with folding and lock, with
Guarantee to be routed through between main wheel and backing pin.
Wheel carrier 5 lower end is hinged with seat frame 3, and seat frame 3 is provided with a seat 2, seat frame 3 bottom and foot
Treadle 1 connects.
Hydraulic climbing mechanism 8, hydraulic climbing mechanism 8 lower end and auxiliary wheel carrier is secured below head piece 7
9 fixing connections, jockey pulley wheel carrier 9 two ends cross out and each equipped with an auxiliary wheel 11, and auxiliary wheel carrier passes
The both sides of main wheel frame, and be provided with roller 10 and main wheel frame two side contacts so that auxiliary wheel carrier can main wheel frame it
Between move up and down.The ring 6 of tiing knots of whole device of being easy to sling is set in the upper end of main wheel frame 5.
In the diagram, hydraulic climbing mechanism 8 is similar to the structure of hydraulic jack, and it is by large tank 17, big
Piston 16, small oil tank 22, valve piston 21, fuel tap 24, crank 20, fuel tank 25 form.Large tank 17
Inside it is provided with big piston 16, in small oil tank 22, is provided with valve piston 21, small oil tank 22 and the passage of large tank 17
Being provided with check valve 18, small oil tank is provided with check valve 23 with the passage of fuel tank, and large tank 17 is logical with fuel tank 25
Road is provided with fuel tap 24, and valve piston 21 is hinged with the middle part of crank 20, and the head end of crank cuts with scissors with crank bearing 19
Connecing, shake crank 20 can drive valve piston to move in small oil tank.The upper end of big piston 16 and head piece 7
Below affixed.Hydraulic climbing mechanism is by the up and down motion of big piston so that whole hydraulic climbing mechanism is stretched
Length or contraction, thus drive auxiliary wheel carrier to be moved upwardly or downwardly.
Using method:
First at each parts of ground check, confirm that hydraulic climbing mechanism 8 is the state of tightening up, hydraulic climbing mechanism
Fuel tap is closed mode.Utilization is tied knots after driving winches on shaft tower by ring 6, is opened by backing pin 4, makes main wheel
12 are positioned on the ground wire of transmission line of electricity, and close backing pin 4.Maintainer is seated on seat 2, and foot is placed
On foot-driven lever 1, fastening seat belts, slip driving overhauls simultaneously.Owing to seat 2 is to pass through seat
Frame 3 is hinged with the lower end of main wheel frame 5, after maintainer takes seat so that center of gravity is less than ground wire nature
Pendency, it is ensured that the safety of maintainer.
When main wheel 12 advances on ground wire and encounters barrier (such as damper), maintainer can shake
The crank 20 of hydraulic climbing mechanism 8 injects hydraulic oil from small oil tank 22 to large tank 17 so that big piston
16 move upward, and are connected owing to big piston 16 upper end is fixing with below head piece 7, the most whole hydraulic pressure
Lifting body stretch downward, drives the auxiliary wheel carrier 9 being positioned at hydraulic climbing mechanism lower end to decline, until auxiliary
The auxiliary wheel 11 at wheel carrier two ends and ground contact and replace main wheel stress.At this moment main wheel 12 has built up,
And between main wheel and ground wire, define gap, when this spacing is more than obstacle height, utilize auxiliary wheel
11 are slidably advanced, and can continue not such as above-mentioned spacing to make hydraulic climbing mechanism increase, until this spacing is big
In obstacle height.When the trailing wheel sliding into auxiliary wheel 11 encounters barrier (damper), due to master
Wheel 12 has passed over barrier, and maintainer opens the fuel tap 24 of hydraulic climbing mechanism 8 and connects large tank
17 with the passage of fuel tank 25, in making large tank, hydraulic oil returns fuel tank 25, and big piston 16 moves downward,
Hydraulic climbing mechanism 8 being shunk, allows two main wheels 12 contact ground wire, auxiliary wheel carrier 9 rises also simultaneously
Returning to original state, such driving can utilize again two main wheels 12 to advance, when driving slides into check man
Screwing brake valve 13 after Wei, personnel can carry out operation.
Invention described above embodiment, is not intended that limiting the scope of the present invention.Any
Amendment, equivalent and the improvement etc. made within the spirit and principles in the present invention, should be included in the present invention
