Abstract
The utility model discloses the unidirectional speed-limiting control device of a kind of road railer, belong to coal mine roadway transport field.Comprise wheel carrier, main shaft is installed by bearing II in wheel carrier both sides, main shaft is provided with the fifth wheel contacted with road railer orbit by bearing I and free-wheel clutch, when road railer is descending, fifth wheel drives main axis by free-wheel clutch, main shaft is also provided with the Centrifugal Releaser controlling road railer brake device.The utility model realizes controlling road railer and only when descending, produces braking, avoids the damage that up braking brings winch and steel rope, for the safety of the personnel that ride provides safeguard.
Description
Technical field
The utility model relates to coal mine roadway transport field, especially a kind of unidirectional speed-limiting control device, is applied to mine or coal mine roadway road railer.
Background technology
In existing inclined shaft tunnel, in order to meet the needs of personnel's transport in mine or coal mine roadway, people's device transported by the card rail that adopts more.This road railer for power with single rope lifting winch, is realized road railer travelled to and fro between ramp upper and lower side by put rope and the serving of winch.Card rail people car speed-limit device is generally two-way speed limiting, namely all triggers brake equipment to implement braking by Centrifugal Releaser action during vehicle uplink and downlink hypervelocity.After vehicle driving down speed exceedes setting value, speed-limit device implements braking, and now winch is for putting rope form state, stops can not produce any injury to steel rope and winch so anxious, also ensure that the safety by bus of personnel by bus simultaneously; After vehicle speed uplink exceedes setting value, speed-limit device implements braking; now winch is in serving state; suddenly stop to cause lineoutofservice signal pull sharply to increase; and due to single rope lifting winch No-mistake Principle fender guard; vehicle stops moving ahead but winch motor still works; very major injury can be produced to the motor of winch, so the up braking of vehicle very easily causes damage to winch and steel rope, and bring potential safety hazard to personnel by bus.
Utility model content
The utility model technical issues that need to address are to provide the unidirectional speed-limiting control device of a kind of road railer, achieve vehicle and only when descending, produce braking, avoid the damage that up braking brings winch and steel rope, for the safety of the personnel that ride provides safeguard.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
The unidirectional speed-limiting control device of road railer, comprise wheel carrier, main shaft is installed by bearing II in wheel carrier both sides, main shaft is provided with the fifth wheel contacted with road railer orbit by bearing I and free-wheel clutch, when road railer is descending, fifth wheel drives main axis by free-wheel clutch, main shaft is also provided with the Centrifugal Releaser controlling road railer brake device.
The further improvement of technical solutions of the utility model is: described bearing II at least one be unilateral bearing, when road railer is up, bearing II stops main axis.
Owing to have employed technique scheme, the technological advance that the utility model obtains is:
Adopt road railer unidirectional speed-limiting control device to achieve vehicle and only when descending, produce braking, avoid the damage that up braking brings winch and steel rope, provide safety control for personnel by bus.
Unilateral bearing coordinates with Centrifugal Releaser and uses, and does not brake and provides guarantee, avoid accidents for vehicle is up.

Fig. 1 is the utility model structure principle chart;
Wherein, 1, wheel carrier, 2, bearing II, 3, bearing I, 4, main shaft, 5, free-wheel clutch, 6, fifth wheel, 7, Centrifugal Releaser.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further details:
As shown in Figure 1, the unidirectional speed-limiting control device of road railer, comprise a wheel carrier 1, a main shaft 4 is fixed by bearing II 2 in wheel carrier 1 both sides, main shaft 4 in wheel carrier 1 fixes a fifth wheel 6 by a bearing I 3 and a free-wheel clutch 5, a Centrifugal Releaser 7 also fixed by the main shaft 4 that main shaft 4 stretches out wheel carrier 1.
The relative sense of motion of free-wheel clutch 5 Internal and external cycle is contrary with the sense of motion of fifth wheel during vehicle driving down 6, therefore free-wheel clutch 5 Internal and external cycle geo-stationary when road railer is descending, when road railer is up, free-wheel clutch 5 Internal and external cycle can relatively rotate, and is equivalent to bearing; Bearing II 2 at least one be unilateral bearing, if the direction of relative movement of two bearing II 2 Internal and external cycles is consistent when bearing II 2 is unilateral bearing, when road railer is up, the direction of relative movement of bearing II 2 Internal and external cycle is contrary with the sense of motion of fifth wheel 6, namely bearing II 2 Internal and external cycle geo-stationary when road railer is up also stops main shaft 4 with fifth wheel 6 one pieces rotation, and when road railer is descending, bearing II 2 is equivalent to plain bearing.
Working process of the present utility model is as follows:
During vehicle driving down, fifth wheel 6 and rail contact start to rotate, free-wheel clutch 5 Internal and external cycle geo-stationary, fifth wheel 6 drives main shaft 4 to rotate by free-wheel clutch 5 transmitting torque, now bearing II 2 is equivalent to bearing, can not produce inhibition to the rotation of main shaft 4, the Centrifugal Releaser 7 on main shaft 4 is also with rotations of 4 one pieces, main shaft, and Centrifugal Releaser 7 action when vehicle driving down speed exceedes setting value thus the brake equipment controlling road railer realize braking; When road railer is up, fifth wheel 6 and rail contact start to rotate, free-wheel clutch 5 Internal and external cycle can be movable relatively, be equivalent to bearing, therefore main shaft 4 can not along with fifth wheel 6 one pieces rotation, bearing II 2 Internal and external cycle geo-stationary when road railer is up simultaneously, therefore bearing II 2 stops main shaft 4 to rotate, for the static of main shaft 4 provides double shield, the Centrifugal Releaser 7 on main shaft 4 is also prevented from motion along with 4 one pieces, main shaft, can not trigger Centrifugal Releaser 7.Unilateral bearing coordinates with Centrifugal Releaser 7 and uses, and does not brake and provides guarantee, avoid accidents for vehicle is up.
Road railer only produces braking by adopting road railer unidirectional speed-limiting control device to achieve vehicle when descending, avoids the damage that up braking brings winch and steel rope, provides safety control for personnel by bus.
