Abstract
The utility model relates to a brake device for a winch, which comprises a brake seat, a brake fork, a brake spring, a brake sleeve and a positioning ring. Key points of the design of the brake device are as follows: a cylinder is arranged at the middle part of one end of the brake seat; a sector block is integrated at a side face of the cylinder; the sector block and the cylinder form a sector groove; a sector sliding block in sliding fit with the sector groove is arranged at one end of the brake fork; gear teeth are arranged at the other end of the brake fork, and penetrate through the brake sleeve and the positioning ring in sequence; the brake spring is arranged between the brake seat and the brake fork; one end of the brake spring is blocked in the sector block; and the other end of the brake spring is blocked in the sector sliding block. The brake device adopts simpler structural principle, is more convenient to operate, and is suitable for serving as an improvement of structures of existing like products.
Description
Technical field
The utility model relates to capstan winch, is a kind of winch brake device.
Background technology
Capstan winch is a kind of accessory equipment that applies to automobile, can be used for saving oneself or as draw gear.Existing capstan winch mostly is provided with dead-man's device, and its purpose is exactly when the stall of capstan winch motor in operation, can pin the hauling rope of capstan winch automatically, guarantees to save oneself or the safety when drawing.In the prior art, Granted publication CN200951940Y as the Chinese patent literature publication, September 26 2007 Granted publication day, utility model title " electric capstan ", this patent is to utilize from the spring of brake units and the wipe contact of drum, make and when regaining cable, do not reverse, if also self-actuating brake in time of reversing takes place.Though this structure can realize that structure is comparatively complicated from stopping function.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is to provide a kind of winch brake device to this area, makes it solve comparatively complicated technology problem of existing like product structure.Its objective is and be achieved through the following technical solutions.
A kind of winch brake device, this winch brake device comprises Brake Block, braking fork, retarding spring, braking sleeve, nest, Brake Block connects the braking fork by retarding spring, nest is by the bolted connection braking sleeve outside one end, and Brake Block, braking fork, retarding spring place by in nest, the chamber that braking sleeve constituted.Its main points are that described Brake Block one end middle part is cylinder, the integrated secter pat of cylindrical side constitutes fan groove by secter pat and cylinder, and described braking is pitched an end and is provided with quadrant block with described fan groove bearing fit, the braking fork other end is provided with the gear teeth, and these gear teeth pass braking sleeve and nest successively; Be provided with retarding spring between described Brake Block and the braking fork, described retarding spring one end is stuck in described secter pat, the other end be stuck in described quadrant block.Tighten by braking fork, the Brake Block rotating band spring of moving, make between spring and the braking sleeve and remove Frotteurism, promptly remove brake, realize the draw of capstan winch.When motor stopped operating, spring automatically reset, and promptly spring and braking sleeve rub once more, realized brake.
In the described secter pat one of them is provided with the breach that connects retarding spring one end trip, and one of them in the described quadrant block is provided with the breach that connects retarding spring other end trip.Breach is set, prevents the phenomenon that skidding appears in the trip of retarding spring.
The utility model structural principle is comparatively simple, and it is comparatively convenient to operate, and is suitable as the structural development of existing like product.

The specific embodiment
Now in conjunction with the accompanying drawings the utility model H shape winch brake device is further described, the name of sequence number is called among the figure: Brake Block 1, secter pat 101, fan groove 102, retarding spring 2, trip 201, braking fork 3, the gear teeth 301, quadrant block 302, braking sleeve 4, nest 5.
As Fig. 1～shown in Figure 6, this winch brake device is combined by Brake Block 1, retarding spring 2, braking fork 3, braking sleeve 4, nest 5, Brake Block one end middle part is a cylinder, the integrated secter pat 101 of cylindrical side, constitute fan groove 102 by secter pat and cylinder, the retarding spring two ends are provided with trip 201, and Brake Block one end is provided with the quadrant block 302 that cooperates with fan groove, and the Brake Block other end is provided with the gear teeth 301.The trip of retarding spring one end and the Brake Block wherein breach on the secter pat collude mutually, and the trip of the retarding spring other end colludes mutually with breach on one of them quadrant block of braking fork.
Principle of work of the present utility model is: when driven by motor braking fork rotates, because Brake Block is as traction end, produce relative rotation between described braking fork and the Brake Block, tighten up retarding spring, remove friction between the wall of retarding spring and braking sleeve, thereby realize traction; When the motor stall, owing to do not produce relative rotation between Brake Block and the braking fork,, spring do not tighten so not producing, so the generation of the wall of retarding spring and braking sleeve rubs, play braking effect.
