Abstract

The utility model relates to a lifting and lowering device with a fixing structure. An outer shell is composed of two half shell bodies which are assembled with each other into a whole, and a control group is arranged at one side of a groove wheel in the outer shell. The control group is a box body of which the top end and the bottom end are in an opening shape. A roller is pivoted in the box body, and a tooth face of which the upper end is inclined towards the roller is fixedly arranged in the box body. A clamping control wheel of which the circumference is provided with control teeth is movably arranged in the box body. A stop lever is arranged on the opening of the bottom end of the box body, a lifting and lowering rope is penetrated between the roller and the clamping control wheel from the upper end of the box body, and the lifting and lowering rope is penetrated from the lower end of the box body. By judging whether the rope is thrown to the clamping control wheel or not, the rope which is in a fixing state or not can be realized. The utility model has the characteristics of simple operation, labor saving, time saving and firm positioning.

Description

Jacking system with fixed sturcture

The utility model relates to jacking system, refers in particular to a kind of jacking system with fixed sturcture.

Jacking system commonly used mainly comprises pulley mechanism, object can be hung aloft, reducing ground takies and maybe will keep in repair object and sling, be convenient to operation, but jacking system commonly used being provided with fixed sturcture, often is with the mode of rope binding the object of hanging to be fixed, time-consuming in the operation, inconvenience, and bundle the not firm object landing of hanging that makes, easily break object or injure ground personnel or article by a crashing object.

The purpose of this utility model is to provide a kind of jacking system with fixed sturcture, overcomes the drawback of prior art, reaches the purpose of simple to operate, time saving and energy saving and firm position.

The purpose of this utility model is achieved in that a kind of jacking system with fixed sturcture, comprise that the top is provided with the shell of ring body and is hubbed at the interior sheave of shell, it is characterized in that this shell is combined into one by the two halves housing, sheave one side in the enclosure is provided with the stopper group, this stopper group is the opening-like box body in top and bottom, be pivoted in this box body roller and set firmly its upper end towards the roller direction bevelled flank of tooth, the blocking wheel that circumference is provided with the tooth of pulling is movably placed in this box body, and this box body bottom end opening place is provided with pin.

Edge between this two halves housing is provided with side plate.

The inside of this half housing is provided with the plurality of fixed sheet that fixes the stopper group.

The surface of this roller is provided with embossing.

Major advantage of the present utility model is: by sheave one side in the enclosure the stopper group is set, the lifting rope is penetrated between the roller and blocking wheel of stopper group, by the whipping rope whether to blocking wheel, realize whether rope is stationary state, have simple to operate, the advantage of time saving and energy saving and firm position.

Fig. 4 is a stationary state scheme drawing of the present utility model;

Fig. 5 is the object scheme drawing of hanging of the present utility model;

Consult Fig. 1-Fig. 3, the utility model 1 comprises shell 10, sheave 20 and stopper group 30, wherein shell 10 is combined into one by conjunction 12 by two halves housing 11, the top of shell 10 is provided with ring body 13, edge is provided with side plate 17 between the two halves housing 11, its two halves housing 11 correspondences extend inward out two

hollow sleeves

14 and 15 of socket mutually, conjunction 12 places the center of two

hollow sleeves

14 and 15, sheave 20 is hubbed at the outside of two

hollow sleeves

14 and 15, the inside of two halves housing 11 is provided with plurality of fixed sheet 16, is used to fix stopper group 30.Stopper group 30 is fixed in a side of sheave 20, be the opening-like box body 31 in top and bottom, in the box body 31 near the be pivoted roller 32 of embossed surface of the top end opening place of a side of sheaves 20, a corresponding with it side sets firmly its upper end toward the roller 32 direction bevelled flank of tooth 33, blocking wheel 34 is movably placed in the box body 31, its circumference is provided with the tooth 35 of pulling and can be meshed with the bevelled flank of

tooth

33, and 31 bottom end opening places are provided with pin 36 at box body, is used to stop that blocking wheel 34 drops out box body 31 downwards.

Rope 40 penetrates shell 10 inside by the left side, walks around sheave 20, is penetrated between roller 32 and the blocking wheel 34 by the upper end, passes from stopper group 30 lower ends.

Consult Fig. 4 and Fig. 5, jacking system 1 of the present utility model can be used by majority, as shown in Figure 5, ring body 13 is hung on top ceiling etc. and locates to fix, pulling rope 40, effect by sheave 20 and roller 32 is risen hanging object 2, when hanging object 2 and need the location, and can be with the pulling end of rope 40 to blocking wheel 34 whippings, as shown in Figure 4, rope 40 push card detent rollers 34 rise, and make pull tooth 35 and the flank of tooth 33 engagements of blocking wheel 34 be positioned the top end opening place of box body 31, with rope 40 clip pulling between the tooth 35 at roller 32 and blocking wheel 34 securely, make rope 40 be stationary state, need not tie up solid rope 40 again, it is simple to operate, and is time saving and energy saving, firm position, to hang that object 2 rises or when putting down when need, and only need the pulling end of the rope 40 direction whipping to sheave 20, blocking wheel 34 drops downwards at once, rope 40 is not subjected to the clip effect of roller 32 and blocking wheel 34, be free to downward pulling or upwards loosening, continuation will be hung object 2 and be hung liter or decline, and will be very easy to use.
