Abstract
The invention discloses a wedge type brake used for braking a mining flat car. The wedge type brake is arranged at the bottom of a common mining flat car, the wedge type brake car can be installed after simple transformation is only carried out on the common mining flat car, and the wedge type brake has the advantages of convenience for installation, flexible use and reliable braking. The wedge type brake adopts the following technical scheme as follows: the wedge type brake with a self-locking effect is adopted to improve the braking reliability. The brake can be successfully opened under the heavy-load condition, and a reverse connecting rod structure is adopted. The acting force for relieving braking is enabled to be greater than the acting force for applying braking.
Description
Technical field
The present invention relates to a kind of wedge brake, for the braking of mine platform lorry.
Background technology
Along with the development of mining equipment, the branch of mine platform lorry, brake type flat truck has occurred.Brake type flat truck can under the effect of external connection power, by realizing braking to the clamping of track two sides.Be mainly used in certainly moving of coal face mobile power station, also to can be used in mine, tunnel other heavy with machine equipment or power equipment supply along frequent and certainly the moving of low speed of track, reach simple to operate, conveniently moving, the safety of raising equipment moving object.
Summary of the invention
The technical problem to be solved in the present invention is: provide one to be arranged on bottom common mine platform lorry, carries out simply transforming the drg that can install and use to ordinary flat car.
For improving the reliability of braking, this drg have employed the wedge structure pattern with self-locking action.In order to ensure under case of heavy load can smooth opening drg, have employed trans bar linkage structure.Ensure that the application force of brake off is greater than the application force applying braking.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is the frame of drg shown in Fig. 1 and scotch block structure schematic diagram.
Accompanying drawing 3 is the schematic diagrams of frame structure shown in Fig. 1.
Accompanying drawing 4 is the structural representations of connecting rod assembly shown in Fig. 1.
Detailed description of the invention
Accompanying drawing 1 shows concrete structure of the present invention, and it is made up of support body (1), drg frame (2), braking voussoir (3), connecting rod assembly (4), oil cylinder (5), hinging pin shaft (6) etc.; Use the present invention, two to braking voussoir (3), two cover connecting rod assembly (4), oil cylinder (5) by one group of pinned connection on support body (1).Wherein drg frame (2) is fixed by bolts on support body (1).
To be drg framves (2) with braking voussoir (3) install accompanying drawing 2 coordinates schematic diagram, is processed with guide groove and orienting lug therebetween.Braking voussoir (3) can be slided along the inclined-plane of drg frame (2) under external force freely
Accompanying drawing 3 is the structural representation of shown support body (1), and its base plate, with 4 symmetrical chutes, can produce movement after drg can be made to install bottom hull, to adapt to the interval error of two parallel orbit spacing, and improves the carrying capacity of bend.After drg is installed, between the spacing gusset that drg frame (2) is clipped in support body (1) and the positioning plate of flat truck.Therefore the bolt of fixing dynamic device frame (2) can not bear shearing, effectively can improve service life and the reliability of drg.The positioning plate at support body (1) top can ensure that the stroke of both sides braking voussoir (3) is consistent.
Accompanying drawing 4 is connecting rod assembly (4) structural representation, and with pinned connection between connecting rod and bar head, the pin-and-hole of bar head is slide opening, to eliminate the position skew that connecting rod swing causes.Bar head is connected by lateral pin with braking between voussoir (3) for a pair, and the application force of oil cylinder (5) passes to braking voussoir (3) eventually through lateral pin.
Claims (3)
1. a wedge brake, is characterized in that: it is made up of support body (1), drg frame (2), braking voussoir (3), connecting rod assembly (4), oil cylinder (5), hinging pin shaft (6) etc.; Paired use, is arranged on bottom flat truck, realizes flat truck to the braking of track and releasing under the effect of external propulsion source.
2. be oblique between drg frame (2) according to claim 1 and braking voussoir (3) and with the bearing fit of guide groove, move forward and backward along guide groove under the effect of a pair braking voussoir power outside, can complete the clamping of track side surfaces and unclamp.
3. connecting rod assembly according to claim 1 (4) foundation lever principle is to increase the application force of oil cylinder, and makes the application force of brake off be greater than braking force; All mechanisms are arranged on support body (1) by hinging pin shaft (6) etc., and support body (1) itself plays installation fixation, simultaneously as the limiting component of linkage rod group.
