Abstract
The invention relates to a tractor. The tractor comprises a brake and a microswitch, and further comprises a lever, a brake connecting rod, a microswitch connecting rod and a fixing piece; the brake connecting rod is connected with the brake; the microswitch connecting rod is connected with the microswitch; the brake connecting rod and the microswitch connecting rod are both fixedly connected to the lever; the lever is fixed on the fixing piece; and the fixing piece is fixedly connected to a tractor body. The tractor has the advantages of simple structure, stable and precise braking work and incapability of generating wrong signals due to the working temperature change.
Description
Technical field
The present invention relates to a kind of traction machine, particularly to the brake structural of traction machine.
Background technology
Operation that traction machine is elevator provides power, and active rotating shaft is played braking action by brake therein, be elevator not
The safety device that can lack, makes operating elevator automatically lift car be stopped when cutting off the electricity supply, the electric magnet of brake
On circuit in parallel with motor, therefore elevator run time, electromagnetic actuation, make brake declutch；When elevator stops, then electricity
Magnet discharges, and brake scotch holds braked wheel under the action of the spring tightly, it is achieved mechanical hatching gate is braked.
According to the countries concerned's standard, it is at 0.3-0.5mm that the braking distance of traction machine brake requires, so can guarantee that system
The dynamic time is short, and braking effect is good.But the microswitch stroke of brake is typically greater than 1mm, thus can produce one delayed
Problem, it is possible to after there is microswitch action, brake does not has an action, but certain after microswitch action by the time
Time point starts the situation of action again and occurs, and thus causes braking time elongated, the poor stability of braking.
Summary of the invention
In order to solve deficiency of the prior art, it is an object of the invention to provide a kind of braking operation stably accurately and braking
The Novel traction machine that effect is greatly improved.
To achieve these goals, a kind of traction machine provided by the present invention, including brake and microswitch, also include
Lever, brake linkage, microswitch connecting rod and fixture, described brake linkage is connected with described brake, described fine motion
Switch connecting rod is connected with described microswitch, and described brake linkage and described microswitch connecting rod are fixedly connected with at described thick stick
On bar, described lever is fixed on described fixture, and described fixture is fixedly connected on traction machine fuselage.
Preferably, described brake linkage is connected to midpoint or the lower end of described lever.
Traction machine simple in construction provided by the present invention, braking operation is stably accurate, temperature when will not work because of traction machine
Degree change and produce mistake signal.

Detailed description of the invention
As it is shown in figure 1, a kind of traction machine, including brake 3 and microswitch 5, also include lever 1, brake linkage 2,
Microswitch connecting rod 4 and fixture 6, described brake linkage 2 is connected with described brake 3, described microswitch connecting rod 4 and institute
Stating microswitch 5 to connect, described brake linkage 2 and described microswitch connecting rod 4 are fixedly connected with on described lever 1, institute
Stating lever 1 to be fixed on described fixture 6, described fixture 6 is fixedly connected on traction machine fuselage.
In order to make the brake linkage 2 link position on lever 1 to regulate, brake linkage 2 does not uses with lever 1
Welding manner, but other connected modes that can regulate, such as nut connect, and arrange some through holes on lever 1, allow braking
Device connecting rod 2 passes.Brake linkage 2 is attached to midpoint or the lower end of lever 1.
When described brake 3 impulse stroke is S, and brake linkage 2 stroke being connected with brake is also S, with described thick stick
Described microswitch connecting rod 4 stroke that bar 1 is connected is the S, the S that stroke is N times of the most described microswitch 5 of N times.
The braking distance of described brake 3 is relatively fixed, it is impossible to directly become big, this structure can effectively by
The braking distance of described brake 3, geometric ratio amplification is transferred to described microswitch 5.The letter that described microswitch 5 obtains can be ensured
Number accurate.
The preferred specific embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art
Just many modifications and variations can be made according to the design concept of the present invention without creative work.Therefore, all the art
Logical analysis, reasoning, or a limited experiment are passed through in middle technical staff design concept under this invention on the basis of existing technology
Available technical scheme, all should be within the scope of the present invention and/or in the protection domain that is defined in the patent claims.
