Abstract
The utility model discloses a hydraulic shoe brake comprising a brake wheel. Fixed ends of a left brake arm and a right brake arm, which are provided with shoes, are movably hinged to the machine frame. The moving end of the left brake arm is movably hinged to the middle part of an L-shaped block, and the moving end of the right brake arm is movably hinged to a connection rod, besides, the connection rod is hinged to the vertical end of the L-shaped block. The horizontal end of the L-shaped block is connected with the vertically disposed hydraulic oil cylinder, and the other end of the hydraulic oil cylinder is connected with the machine frame. In the utility model, the hydraulic oil cylinder is vertically disposed on the machine frame, which is disposed on the side surface of the brake arm, thereby the falling of oil droplets leaked from the oil cylinder in the brake wheel can be prevented, and the safety hazard can be removed effectively.
Description
Technical field
The utility model relates to a kind of drg that is used for the mine hoisting winch, specifically relates to a kind of hydraulic pressure shoe brake.
Background technology
Publication number is the disclosed a kind of hydraulic pressure block brake of CN2898431Y patent documentation, form by brake shoe, bearing pin, brake control lever, frame, cylinder tube, piston rod and disk spring, brake shoe is connected with brake control lever by bearing pin, the brake control lever lower end links to each other with frame, the brake control lever upper end is equipped with cylinder tube and piston rod, between cylinder tube and the piston rod disk spring is installed.Adopt the product of this technical scheme, in use for some time, because the crank motion of piston rod can cause packing element wearing and tearing to a certain degree, and originally there be certain wearing out in packing element under the effect of reasons such as pressure oil, small seepage phenomenon will occur, the hydraulic oil of seepage will drop onto on the work system driving wheel, causes braking force to reduce, deceleration and stopping performance descends, and forms potential safety hazard.
Summary of the invention
The utility model is intended to solve the problems of the technologies described above, and provides a kind of oil cylinder seepage oil droplet of avoiding to fall into hydraulic pressure shoe brake on the brake wheel.
The new technical scheme that adopts of this practicality is: a kind of hydraulic pressure shoe brake, comprise brake wheel, the left and right brake control lever fixed end that brake shoe is installed is movably articulated on the frame, the movable end of left side brake control lever is movably articulated in L shaped middle part, the movable end of right brake control lever is movably hinged connecting rod, connecting rod and L shaped perpendicular end is hinged, and L shaped horizontal end is connected with hydraulic ram one end of vertical placement, and the other end of hydraulic ram is connected on the frame.
When the pressure oil pressure release in the hydraulic ram, the oil cylinder piston withdrawal, the horizontal end that the traction of oil cylinder termination is L shaped is to bottom offset, and the distance between the left and right brake control lever movable end progressively shortens under L shaped effect, and brake shoe is held brake wheel tightly, realizes braking; When hydraulic ram pressurizeed, oil cylinder piston ejected, and the horizontal end that the traction of oil cylinder termination is L shaped is to top offset, and the distance between the left and right brake control lever movable end progressively increases under L shaped effect, and brake shoe take-off the brake wheel realizes declutching operation.
The technical program is vertically mounted on hydraulic ram on the frame of brake control lever side, has avoided the seepage oil droplet of oil cylinder to fall on the brake wheel, has eliminated potential safety hazard effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below, in conjunction with the accompanying drawings the specific embodiment of the present utility model is described further.
Fig. 1 has shown a kind of hydraulic pressure shoe brake, comprise brake wheel 1, on left side brake control lever 3, the right brake control lever 4 brake shoe 2 is installed, the fixed end 31 of left side brake control lever 3 is movably articulated on the frame 5, the fixed end 41 of right brake control lever 4 is movably articulated on the frame 5, the movable end 32 of left side brake control lever 3 is movably hinged L shaped 6 middle part, the movable end 42 of right brake control lever 4 is movably hinged connecting rod 7, connecting rod 7 is hinged with L shaped 6 perpendicular end 61, L shaped 6 horizontal end 62 is connected with hydraulic ram 8 one ends of vertical placement, and the other end of hydraulic ram 8 is connected on the frame 5.
