Horizontal pushing and clamping type two-cylinder double-side braking retarder actuator

Abstract

The invention relates to a horizontal pushing and clamping type two-cylinder double-side braking retarder actuator comprising a bearer beam, inner supports, outer supports, brake rails and cylinders. The inner supports and the outer supports are arranged on two sides of two base rails, respectively. One brake rail is disposed on the inner supports. The other brake rail is arranged on the outer supports. The cylinders arranged over the bearer beam are connected with the inner supports. A brake unit is provided for any base rail. The actuator can be used with an electro-hydraulic control system to allow single-rail vehicle control and double-rail vehicle control, six-stage control can be achieved, many-stage vehicle control is available, and vehicle control precision is improved. The use of rectangular guide rails ensures large contact area of a kinematic pair and small pressure; lubricating is easy; wear loss is low; the service life is long; a processing technique is simple.

Description

technical field [0001] The invention relates to a dual-cylinder flat-push clamp type double-sided brake reducer actuator. Background technique [0002] At present, the reducer actuators used in hump automation in my country are divided into gravity reducer actuators and non-gravity reducer actuators. The main structures are swing clamp type and flat push inner support type. [0003] The mechanical structure of the actuator of the swing-clamp type double-sided brake reducer is relatively complicated, the manufacturing process of the clamp is complicated, the cost is high, and the sleeve of the clamp is easy to wear during work. The actuator parts of the swing clamp type double-sided brake reducer actuator are located under the basic rail, which causes inconvenience to installation and maintenance. [0004] The actuators of flat-push inner support type reducers are generally single-sided brakes. Under the same braking force requirements, compared with other reducer actuators,...

Problems solved by technology

[0003] The mechanical structure of the actuator of the swing clamp type double-sided brake reducer is relatively complicated, the manufacturing process of the clamp is complicated and the cost is high, and the sleeve of the clamp is easy to wear during work

The actuator parts of the swing clamp type double-sided brake reducer actuator are located under the basic rail, which makes installation and maintenance inconvenient

[0004] The actuators of flat-push inner support type reducers are generally single-sided brakes. Under the same braking force requirements, compared with other reducer actuators, they need to provide higher system pressure, which is not conducive to oil cylinders, hydraulic pipelines, seals, etc. The use of hydraulic system actuators

[0005] The existing gravity reducer actuators of Hump Automation are divided into single-track control vehicles and double-track control vehicles, which cannot realize single-track control vehicles and dual-track vehicle control at the same time. The non-gravity reducer actuators can provide a maximum of 4 control stages. class
