Abstract

The utility model discloses a lifting clamp which comprises two rotatably connected clamping jaws with handles and claws, and a lifting steel wire rope connected to one end of each handle, wherein an elastic pre-tensioning device is further arranged between the two handles. The lifting clamp, through the elastic pre-tensioning device between the two handles, can firmly hook a lifted object and prevent the object from loosing.

Description

Stone tongs
Technical field:
The utility model relates to a kind of hanging device, particularly a kind of stone tongs.
Background technology:
In hanging device, often can use stone tongs; existing stone tongs generally as shown in Figure 1; comprise two jaws with jug and claw that are rotatably connected; and the lifting steel rope that connects two handles one end; in practical operation, first claw is snapped on lifting object, and then by driving, hang steel rope lifting object is transported to given place.After claw is snapped on lifting object, until traveling crane plays lifting object, workman need to break handle with hand like this, in case claw comes off, and careless slightly claw comes off, need to again break handle into two with one's hands claw is opened, again block lifting object, and firmly break handle in case claw comes off again, therefore lift efficiency low, and if driving firmly loosening before slinging, the part that claw blocks lifting object reduces, after easily slinging, lifting object drops, and causes the accident.Therefore the safety factor of this stone tongs is also lower.
Summary of the invention:
Technical problem to be solved in the utility model is to provide a kind of firm safe stone tongs, it comprises two jaws with jug and claw that are rotatably connected, and the lifting steel rope that connects two handles one end, wherein between described two handles, be also provided with elasticity pre-tightening apparatus.
The utility model further technical characterictic is:
Described elasticity pre-tightening apparatus is a spring.
Described elasticity pre-tightening apparatus comprises the double-screw bolt being arranged on a handles and the setting nut coordinating with double-screw bolt, also comprises a spring, one end of its medi-spring and Stud connection, and the other end of spring is connected with another handle.
Described elasticity pre-tightening apparatus comprises the double-screw bolt being arranged on respectively on two handles and the setting nut coordinating with double-screw bolt, also comprises the spring with two Stud connections.
Described elasticity pre-tightening apparatus comprises two springs, and one end of two springs is arranged on respectively on two handles, also comprises the positive tooth screw rod and the anti-tooth screw rod that are connected with two spring other ends, and the positive and negative tooth tensioning nut that connects positive tooth screw rod and anti-tooth screw rod.
The beneficial effects of the utility model are: the relatively traditional stone tongs of the utility model stone tongs, owing to being provided with elasticity pre-tightening apparatus between two handles, therefore can hook jail lifting object, can not get loose, Hoisting Security coefficient improves, lifting efficiency also improves greatly, and can reduce workman's manual operations.
Accompanying drawing explanation:
Fig. 1 is the structural representation of existing stone tongs;
Fig. 2 is the structural representation of the utility model stone tongs one embodiment;
Fig. 3 is the structural representation of an example of the utility model Elastic pre-tightening apparatus;
Fig. 4 is the structural representation of another example of the utility model Elastic pre-tightening apparatus;
Fig. 5 is the structural representation of another example of the utility model Elastic pre-tightening apparatus.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described further:
With reference to Fig. 2-Fig. 5, Fig. 2 is the structural representation of the utility model one embodiment.As shown in Figure 2, a kind of stone tongs, comprises two jaws 3 with jug 1 and claw 2 that are rotatably connected, and the lifting steel rope 4 that connects two handles 1 one end, wherein between described two handles 1, is also provided with elasticity pre-tightening apparatus 5.In the embodiment shown in Figure 2, described elasticity pre-tightening apparatus 5 is a spring.This spring, according to the size configure of lifting object, makes the degree that claw 2 opens just can block and clamp the lifting part of lifting object.
Fig. 3 is the structural representation of 5 one examples of the utility model Elastic pre-tightening apparatus, in the example depicted in fig. 3, described elasticity pre-tightening apparatus 5 comprises the double-screw bolt 501 being arranged on a handles 1 and the setting nut 502 coordinating with double-screw bolt 501, also comprise a spring 503, one end of its medi-spring 503 is connected with double-screw bolt 501, and the other end of spring 503 is connected with another handle 1.
Fig. 4 is the structural representation of the utility model Elastic pre-tightening apparatus 5 another examples, described elasticity pre-tightening apparatus 5 comprises the double-screw bolt 501 being arranged on respectively on two handles 1 and the setting nut 502 coordinating with double-screw bolt 501 in the example depicted in fig. 4, also comprises the spring 503 being connected with two double-screw bolts 501.
Fig. 5 is the structural representation of another example of the utility model Elastic pre-tightening apparatus, described elasticity pre-tightening apparatus 5 comprises two springs 503 in the example depicted in fig. 5, one end of two springs is arranged on respectively on two handles 1, also comprise the positive tooth screw rod and the anti-tooth screw rod 501 that are connected with two spring 503 other ends, and the positive and negative tooth tensioning nut 502 that connects positive tooth screw rod and anti-tooth screw rod 501.
In the example of the elasticity pre-tightening apparatus 5 shown in Fig. 3, Fig. 4 and Fig. 5, Fig. 3 and Fig. 4 make the pre-opening degree of claw 2 just can block and clamp the lifting part of lifting object by setting nut 502; Fig. 5 makes the pre-opening degree of claw 2 just can block and clamp the lifting part of lifting object by positive and negative tooth tensioning nut 502.
In actual applications, first with manpower, break claw into two with one's hands claw is snapped on lifting object, and then by driving, hang steel rope lifting object is transported to given place.Which kind of form no matter elasticity pre-tightening apparatus 5 adopt, and all will, according to the size configure of lifting object, make the pre-opening degree of claw 2 just can block and clamp the lifting part of lifting object.Like this, existence due to elasticity pre-tightening apparatus 5, even if loose one's grip, claw 2 can not come off yet, when driving hangs after steel rope 4, claw 2 is understood the tighter of hooks, and in the operational process of driving a vehicle like this, lifting object can not get loose, and Hoisting Security coefficient improves, lifting efficiency also improves greatly, and can reduce workman's manual operations.
Although the utility model has been described the specific embodiment herein, coverage of the present utility model is not limited to this.The utility model is contained all technical schemes of falling in fact within the scope of the claims under all instructions on literal or in equivalents, and protection domain of the present utility model is as the criterion with claims.
