Description
Technical field
The present invention relates to a kind of switching machines, and in particular to a kind of hand-operated lever-type switching machine.
Background technique
The inside slope of metal mine designs on ramp turnout is singly opened, and in the selection to switching machine, is initially
Using the switching machine of automatically controlled hydraulically extensible rod-type, in use process, since subsurface environment is moist, the muddy water in mine car in addition
Be easy to be splashed on ramp, to inside switching machine electric elements and Hydraulic Elements cause fatal influence, often to tie up
It repairs or replaces, detrimental effect is brought to production, while improving the cost of production again.Switch is gone in employment on the slope
When, because slope is wet and slippery, great threat is caused to the personal safety of employee.
Summary of the invention
The technical problem to be solved by the invention is to provide the hand-operated lever-type switching machines that one kind can reduce production cost.
The technical solution adopted by the present invention to solve the technical problems is: a kind of hand-operated lever-type switching machine, including spring,
Short screw rod, long screw, hook, wirerope, pulley, balance pivot and lever；The short screw rod is mounted on the straight trip rail of side
On point, the spring is mounted on short screw rod, and the both ends of the short screw rod are fixed with fastener, and point is made to be close to straight trip steel
Rail adjusts the elastic of spring, and the moving distance of spring is made to meet the distance that other side point is close to corresponding straight trip rail just；Institute
Long screw is stated to be mounted between two points；The hook is connected with the point of the other side, wirerope respectively, and the wirerope bypasses
Pulley is connected with lever, and the lever is mounted on balance pivot.
Further, the pulley is two, is fixed in wall by supporting element respectively.
Further, the balance pivot is fixed in wall by supporting element.
Further, the long screw makes the distance of two points be fixed on 540mm.
Further, the fastener is nut.
The hand-operated lever-type switching machine of the present invention, using elastic, the short screw rod of spring positioning function the characteristics of carry out group
It closes, wherein using the characteristic of spring automatic reset, change the displacement of point position, to meet the needs of to track lane change.
The present invention is a kind of switching machine that one direction automatically resets, but can also be real by increasing other auxiliary accessories
The semi-automatic change rail of existing twocouese.
Compared with prior art, the invention has the characteristics that
1) structure is simple, and cost of manufacture is cheap.Compared with expensive automatically controlled hydraulically extensible rod-type switching machine, life can be substantially reduced
Produce cost.
2) easy to operate understandable, it is easier to find when ging wrong.
3) maintenance and maintenance are simple.
4) securely and reliably, especially suitable for bad environments in the case where use.

Spend rail, 10. guard rails, 11. card rails, the 12. rut hearts, 13. points, 14. walls.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and embodiments.
Embodiment
Referring to Fig.1, a kind of hand-operated lever-type switching machine, including spring 1, short screw rod, long screw 2, nut 3, hook 4, steel
Cord 5, pulley 6, balance pivot 7 and lever 8；The short screw rod is mounted on the straight trip rail and point 13 of side, the bullet
Spring 1 is mounted on short screw rod, and the both ends of the short screw rod are fixed with nut 3, and point 13 is made to be close to straight trip rail, adjusts spring 1
It is elastic, so that the moving distance of spring 1 is met the distance that other side point 13 is close to corresponding straight trip rail just；The long screw
2 are mounted between two points 13；The hook 4 is connected with the point 13 of the other side, wirerope 5 respectively, and the wirerope 5 bypasses
Pulley 6 is connected with lever 8, and the lever 8 is mounted on balance pivot 7.
In the present embodiment, the pulley 6 is two, is fixed in wall 14 by supporting element respectively.
In the present embodiment, the balance pivot 7 is fixed in wall 14 by supporting element.
In the present embodiment, the long screw 2 makes the distance of two points 13 be fixed on 540mm.
When mine car passes through point, unsuitable too fast (≤10 meter of speed/per second), gently to pass through, avoid derailing of mine car.
Installation steps:
1. the distance of two points 13 is fixed on 540mm with long screw 2；
2. short screw rod is mounted on the straight trip rail and point 13 of side, spring 1 is mounted on short screw rod, and the both ends of short screw rod are solid
Surely there is nut 3, point 13 is made to be close to straight trip rail, adjust the elastic of spring 1, meet the compression distance of spring 1 just another
Side point 13 is close to the distance (as shown in Figure 2) of corresponding bend rail；
3. hook 4 is mounted on the point 13 of the other side；
4. pulley 6 is two, it is fixed in wall 14 by supporting element respectively；
5. balance pivot 7 is fixed in wall 14 by supporting element；
6. bypassing pulley 6 with wirerope 5, hook 4 is connected and is regulated with lever 8 length of wirerope 5.
The course of work:
1. when mine car is up run from following straight rail, using the weight of mine car, wheel can be close to straight rail side point it is strong
Row squeezes, and passes through mine car；After mine car passes through, point continues the shape for being held against straight rail under the force of a spring
State；
2. in the state of existing, it can be directly to the bend on side when mine car gets off from above；
3. pulling the hook on point using lever when wanting that mine car is allowed directly to get off along straight rail, make the rut for linking up with one side
Point is close to rail, and the point of spring over there concedes access directly down then far from straight rail, mine car can be made to transport directly down
Row；After mine car passes through, lever is unclamped, point will continue to the state for being held against straight rail again under the force of a spring.
