Abstract
The utility model provides a braking device with a self-locking mechanism for a small dispatching winch. The braking device with the self-locking mechanism for the small dispatching winch is formed by improving the conventional braking device for the small dispatching winch. The braking device comprises a pair of ratchet lug boards fixed on a braking valve belt, a swing bolt, a braking handle and a self-locking mechanism, and is characterized in that one end of the swing bolt is connected with the ratchet lug boards through pin shafts, and the other end of the swing bolt is connected with the lower part of the braking handle; and a positioning handle of the self-locking mechanism is connected with the upper part of the braking handle through the pin shaft. The braking device for the small dispatching winch comprises a positioning handle, a pull rod and a sliding block; the positioning handle is connected with the upper part of the braking handle through the pin shaft; the upper end of the pull rod is connected with the braking handle through an iron wire; and one end of a spring is connected with the pull rod, and the other end of the spring is connected with a sliding block matched with tooth grooves of the ratchet lug boards. Compared with the conventional braking device for the small dispatching winch, the braking device with the self-locking mechanism for the small dispatching winch provided by the utility model not only can effectively prevent galloping accident from happening, but also has the advantages of simplicity and safety in operation, reasonable and simple structure and low cost.
Description
Technical field
The utility model relates to the brake gear of colliery with mechanical small-sized car hauler, exactly is a kind of small-sized car hauler brake gear with self-locking mechanism.
Background technology
Car hauler be mainly used under the coal mine or other leaning angle less than haul mine car and other auxiliary carrying work in 30 ° the tunnel, also can be used on stope or driving face and load and go up scheduling marshalling mine car.Its principle of work is to accomplish the deceleration and the transmission of winch through two-stage planet and the relocation mechanism that adopted.Thereby rotating through the control motor and the difference of handling two brakes are stopped tight state realize just changeing, reverse of capstan drum and stall realization to the traction of weight, transfer and stop three kinds of mode of operations.At present, because two brake gears do not have catch gear, continuous shaking under the machine works state; Thereby during operation, the operator presses the brake handgrip, and the brake handgrip drives the eyelet bolt rotation and holds the strap of the brake tightly; And when work, pin, can not loose one's grip, so the workman occurs tired when long-time operation easily; always Add not enough understanding, occur the winch runaway accident easily winch braking mechanism safety regulation for operations.
The utility model content
The purpose of the utility model is to existing defective, provides a kind of to people and not only can prevent runaway accident effectively, and also simple to operate, safety, rational in infrastructure, simple, the small-sized car hauler brake gear of band self-locking mechanism with low cost.
It is to be improved by existing small-sized car hauler brake gear to form for the utility model; Comprise a pair of ratchet otic placode, eyelet bolt, brake handgrip and the self-locking mechanism that are fixed on the brake strap of the brake; Its characteristic is used for: eyelet bolt one end is connected with the ratchet otic placode by bearing pin; The other end is connected in brake handgrip bottom by bearing pin, and the location handgrip of self-locking mechanism is connected in brake handgrip top by bearing pin.
Described car brake gear comprises location handgrip, pull bar and slide block, and the location handgrip is connected in brake handgrip top by bearing pin, and the pull bar upper end is connected with the brake handgrip by iron wire, and spring one end connects pull bar, and the other end connects the slide block that is complementary with ratchet otic placode alveolus.
The effect of the utility model
The utility model is because at existing small-sized car hauler brake gear self-locking mechanism; Therefore not only can prevent runaway accident effectively; And simple to operate, safety, rational in infrastructure, simple, the small-sized car hauler brake gear of band self-locking mechanism with low cost.
