The wheel type movable machine parking brake device comprises a machine body (5), and is characterized by further comprising a first node dowel steel (2) arranged on the machine body (5), wherein the upper portion of the first node dowel steel (2) is connected with a pedal (1), the lower portion of the first node dowel steel (2) is connected with a second node dowel steel (8) through a connecting pin shaft (7), the second node dowel steel (8) is connected with a supporting seat (12) on the machine body (5) through a rotation shaft (11), a braking shoe (10) is arranged on the supporting seat (12), one end of a retracting spring (6) is connected with the second node dowel steel (8), the other end of the retracting spring (6) is connected with the machine body (5), a first convex shoulder (3) is arranged on the first node dowel steel (2), and a second convex shoulder (4) which corresponds to the first convex shoulder (4) is arranged on the machine body (5). The structure is simple, the installation applicability is strong, the simple structure improves the matching technical performance, and convenient operation improves the braking operation ability.
Description
Technical field:
The pin operation parking and braking mechanism technical field that the utility model relates to especially relates to a kind of wheeled mechanically moving holding brake device.
Background technology:
At present, the emergency brake system of known wheeled mobile device can be divided into by type of drive: manual click formula, double-legged pedal type, single pedal plate locating dowel pin formula, the sort of type of drive no matter, from the driver train to the road wheel, its power transmission is steel rope or leverage, by brake strap locking road wheel, pin driver train by catch gear then and reach the braking purpose.But separating glancing impact, all can not reach the purpose of separating braking by the direct control driver train, needing earlier to operation again after the driver train release.Separating glancing impact in manual click formula needs specialized structure to allow pawl-and-gearing throw off, and to the reverse operation brake-applying handle of braking, this mode is mechanically used very extensive in walking, but is not suitable for separating braking with the pin operation; The both feet pedal type is provided with brake pedal and conciliates brake pedal, and structure is too complicated; Single pedal plate locating dowel pin formula reaches the locked pedal of glancing impact locating dowel pin when pedal depresses, and separating glancing impact needs the locating dowel pin return to realize, adopts pin or hand all inconvenient by the operation of locating dowel pin return.
Summary of the invention:
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of wheeled mechanically moving holding brake device is provided.Thereby efficiently solve problems of the prior art.
The purpose of this utility model can be by realizing by the following technical solutions: described a kind of wheeled mechanically moving holding brake device, include body (5), be characterized in also including described body (5) and be provided with first segment dowel bar (2), first segment dowel bar (2) top links to each other with pedal (1), first segment dowel bar (2) bottom links to each other with the second joint dowel bar (8) by connecting bearing pin (7), the second joint dowel bar (8) links to each other with bearing (12) on the body (5) by rotating shaft (11), bearing (12) is provided with brake strap (10), pull back spring (6) one ends link to each other with the second joint dowel bar (8), pull back spring (6) other end links to each other with body (5), first segment dowel bar (2) is provided with first convex shoulder (3), and body (5) is provided with and cooresponding second convex shoulder of first convex shoulder (3) (4).
Brake strap (10) on the described bearing (12) and the corresponding setting of wheel (9), brake strap (10) is fixed with the relative position of the second joint dowel bar (8).
Described a kind of wheeled mechanically moving holding brake device, its beneficial effect comprise that it stretches out a convex shoulder in the first segment dowel bar relevant position that links to each other with stretcher.Reach braking road wheel state at the glancing impact push down on the pedal by brake strap, keep pedal state, the moving reach down of generation of pin or after move pedal, the first segment dowel bar rotates around its bearing pin that is connected with the second joint dowel bar, convex shoulder on it contacts with another convex shoulder on the body and reaches and make the pedal can't return, reaches locked purpose; Separating glancing impact, a little push down on the pedal makes two convex shoulders separate pedal return under the effect of tire antagonistic force and pull back spring to counter-rotation pedal and first segment dowel bar.In whole process owing to the reason of pull back spring and tire antagonistic force, pin is easy to the perception braking and conciliates braking position, its single pedal plate, once the cover operating structure can finish braking, locked, separate braking procedure, simple in structure, the installation applicability is strong, and structure simple improved supporting manufacturability; Its operation convenient improved the handling of braking.
Description of drawings:
Fig. 1 is a non-braking mode structural principle scheme drawing of the present utility model;
Fig. 2 is a braking mode structural principle scheme drawing of the present utility model.
The specific embodiment:
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing:
See Fig. 1, described a kind of wheeled mechanically moving holding brake device, include body 5, be characterized in also including described body 5 and be provided with first segment dowel bar 2, first segment dowel bar 2 tops link to each other with pedal 1, first segment dowel bar 2 bottoms link to each other with the second joint dowel bar 8 by connecting bearing pin 7, the second joint dowel bar 8 links to each other with bearing 12 on the body 5 by rotating shaft 11, bearing 12 is provided with brake strap 10, pull back spring 6 one ends link to each other with the second joint dowel bar 8, pull back spring 6 other ends link to each other with body 5, and first segment dowel bar 2 is provided with first convex shoulder 3, and body 5 is provided with and first convex shoulder, 3 cooresponding second convex shoulders 4.
Described a kind of wheeled mechanically moving holding brake device, it is at glancing impact, see Fig. 2, foot pedals 1, make first convex shoulder 3 on the first segment dowel bar 2 snap in second convex shoulder 4 on the body 5, first segment dowel bar 2 drives the second joint dowel bar, 8, the second joint dowel bars, 8 drive brake straps 10 and compresses wheel 9, realizes braking.
