Abstract
The utility model provides a stopping device for lifting machine, includes the belt shaft that is equipped with on the lifting machine, the one end of belt shaft sets up the belt pulley, the other end of belt shaft is equipped with full cycle crimp mechanism, full cycle crimp mechanism includes stopping frame, pawl, ratchet and ratchet installation cover, be equipped with ratchet installation cover in the stopping frame, the installation ratchet is sheathe in the ratchet installation, be equipped with the pawl directly over the ratchet, the pawl sets up epaxially at the belt pulley. Setting up full cycle crimp mechanism on the lifting machine, having reached and used the same braking effect of brake motor, full cycle crimp mechanism is with low costs, and is not fragile, has not only reduced equipment cost but also has reduced the cost of upkeep of safeguarding in later stage.
Description
Technical field
The utility model relates to the stopping device on a kind of shot-blast apparatus foundry goods being carried out to shot blasting, particularly relates to a kind of lift stopping device.
Background technique
Existing shot-blast apparatus or lift realize braking by braking motor, and braking motor cost is higher, and rate of fault is high, not only reduces working efficiency, and adds maintenance and maintenance cost.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of lift stopping device, can reach the same use of same braking motor and braking effect, reduces maintenance and maintenance cost while reducing equipment cost.
The technological scheme that the utility model adopts is as follows: a kind of lift stopping device, comprise the Pulley shaft that lift is provided with, one end of described Pulley shaft arranges belt pulley, the other end of described Pulley shaft is provided with stopping mechanism, described stopping mechanism comprises retaining frame, ratchet, ratchet and ratchet installation sleeve, and described retaining frame is provided with ratchet installation sleeve, and described ratchet installation sleeve installs ratchet, be provided with ratchet directly over described ratchet, described ratchet is arranged on Pulley shaft.
Described ratchet is provided with the gear teeth, and the gear teeth and described ratchet fasten, and ratchet can firmly be buckled on the gear teeth of ratchet, effectively prevents belt pulley from reversing, realizes stopping function.
The beneficial effect that the technological scheme that the utility model provides is brought is: on lift, arrange stopping mechanism, reach and the braking effect using braking motor the same, stopping mechanism cost is low, not fragile, not only reduces equipment cost and also reduces the maintaining cost in later stage.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is internal structure schematic diagram of the present utility model;
In figure, 1 is retaining frame, and 2 is Pulley shaft, and 3 is ratchet, and 4 is ratchet, and 5 is ratchet installation sleeve.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.
Embodiment one
As shown in Figure 1, 2, a kind of lift stopping device, comprise the Pulley shaft 2 that lift is provided with, one end of Pulley shaft 2 arranges belt pulley, the other end of Pulley shaft 2 is provided with stopping mechanism, stopping mechanism comprises retaining frame 1, ratchet 3, ratchet 4 and ratchet installation sleeve 5, and retaining frame is provided with ratchet installation sleeve 5, ratchet installation sleeve 5 is installed ratchet 4, ratchet 3 is provided with directly over ratchet 4, ratchet 3 is arranged on Pulley shaft 2, and ratchet 4 is provided with the gear teeth, and the gear teeth and ratchet 3 fasten.
This stopping device is bound up on the Pulley shaft 2 of lift, and when lift normal operation, motor-driven belt wheel shaft 2 rotates, and Pulley shaft 2 drives ratchet 3 to rotate, and ratchet 3 driving pawl 4 forward rotates; When occurring needing emergency shutdown, motor stopping, Pulley shaft 2 stops operating simultaneously, and ratchet 3 is firmly buckled on the gear teeth of ratchet 4, effectively prevents belt pulley from reversing, realizes retaining.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
