Abstract
The utility model discloses a pair of portable rescuing hoisting tongs comprising two tong bodies, tong shafts and a jack, wherein the middle parts of the two tong bodies are hinged by the tong shafts; the tong bodies at the front of the tong shafts are tong mouth parts; the tong bodies behind the tong shafts are handle parts; and the handle parts of the two tong bodies are respectively connected with a cylinder body and a top rod of the jack. The portable rescuing hoisting tongs have compact structure and small volume, is applicable to operation in narrow spaces, also has convenient carry, and is applicable to rescuing operation in fields. In addition, the portable rescuing hoisting tongs also have the advantages of saving force.
Description
Technical field
The utility model relates to a kind of hoisting device, especially a kind of portable rescue hoisting tongs.
Background technology
At present, in rescue or other are when needing the perk weight, usually adopt lever perk weight, according to lever principle as can be known, if weight is heavier, then need many people to apply bigger power together, perhaps use longer lever, therefore, this method of rod principle perk weight of utilizing requires to have certain operational space, and application force that need be very big, the occasion that inapplicable space is narrow and small and weight is heavier.Though adopt special hoisting crane can solve starting than weight body problem, the hoisting crane volume is big, Heavy Weight, has the big problem of working space equally, and carries inconvenience.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, provide a kind of can be at small space operation and portable rescue hoisting tongs easy to carry.
To achieve these goals, the technical solution adopted in the utility model is: a kind of portable rescue hoisting tongs, comprise two calipers, pincers axle and jack, the middle part of two calipers is hinged through the pincers axle, caliper before the pincers axle is the jaw part, caliper after the pincers axle is a handle portion, and the handle portion of two calipers is connected with push rod with the cylinder body of jack respectively.
As the preferred version of technique scheme, when hoisting tongs was closed, the inboard of the jaw of described two calipers part fitted, and the thickness after two jaws are partly fitted is convenient to insert the slit between weight from the back to preceding attenuation gradually.
As the preferred version of technique scheme, be provided with anti-slop serrations in the jaw outside partly of described two calipers, increase the friction force between hoisting tongs and the weight.
As the preferred version of technique scheme, the transversal surface of the handle portion of described two calipers is that chamfering quadrangle or chamfering are trapezoidal, tilts when avoiding hoisting tongs perk weight.
Further improvement as above-mentioned preferred version, one of them is lower clamp for described two calipers, another is a upper clamp, the handle portion of lower clamp is positioned at the below of the handle portion of upper clamp, the bottom of described cylinder body is connected with rear end first hinge of the handle portion of lower clamp, and the top of described push rod is connected through second hinge with the middle inside of the handle portion of upper clamp.In addition, be provided with the groove that is used to place described jack in the inboard of the handle portion of described lower clamp, when hoisting tongs was closed, jack all was contained in this groove.
As the further improvement of above-mentioned preferred version, be provided with handle in the outside of the handle portion of described upper clamp.
In the technique scheme, described jack is shaking jack, fluid pressure type jack or electrodynamic type jack.
Compared with prior art, the utility model has the advantages that: compact conformation, volume is little, is applicable to the small space operation, and easy to carry, is applicable to open-air rescue work.In addition, also has the labour-saving advantage.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
As shown in Figure 1, portable rescue hoisting tongs mainly is made up of upper clamp 4, lower clamp 9, pincers axle 8 and jack 1, and the middle part of upper and lower caliper 4,9 is hinged through pincers axle 8, and the caliper before the pincers axle 8 is a jaw part 5, and the caliper after the pincers axle 8 is a handle portion 2.Inboard at the handle portion of lower clamp 9 is provided with the groove that is used to place jack 1, and when hoisting tongs was closed, jack 1 all was contained in this groove.The bottom of the cylinder body of jack 1 is connected with rear end first hinge 6 of the handle portion of lower clamp 9, and the top of the push rod of jack 1 is connected through second hinge 7 with the middle inside of the handle portion of upper clamp 4.In the present embodiment, jack 1 adopts the shaking jack, also can use fluid pressure type jack, electrodynamic type jack.
During work, the jaw part 5 of hoisting tongs inserted to be needed between the weight slit of perk, guarantee that hoisting tongs is placed steadily after, back and forth the handle of rotation jack 1 makes the push rod of jack 1 rise the handle portion 2 of jack-up hoisting tongs, open thereby drive jaw part 5, with weight jack-up.After work was finished, the handle of opposite spin jack 1 was regained the push rod of jack 1, and the handle portion 2 that drives hoisting tongs descends, and simultaneously, jaw part 4 is also closed up.
In addition, for the ease of inserting the slit between weight, the inboard of the jaw part 5 of upper and lower caliper 4,9 fits, and the thickness after two jaw parts 5 are fitted is from the back to preceding attenuation gradually.The outside in the jaw part 5 of upper and lower caliper 4,9 is provided with anti-slop serrations, to increase the hold between hoisting tongs and the weight.The transversal surface of the handle portion 2 of upper and lower caliper 4,9 is that chamfering quadrangle or chamfering are trapezoidal, avoids when guaranteeing hoisting tongs perk weight.
Only be specific embodiment of the utility model below, do not limit protection domain of the present utility model with this; Any replacement and the improvement done on the basis of not violating the utility model design all belong to protection domain of the present utility model.
