Abstract
The utility model relates to a pair of multifunctional pliers for breaking barriers. The pair of multifunctional pliers for breaking barriers is characterized by comprising a scissors type handle, a plier body, a hydraulic transmission mechanism and a plier head, wherein the hydraulic transmission mechanism comprises a plunger pump, a hydraulic cylinder and a connecting rod; the plunger pump is arranged at the inner side of the scissors type handle and is connected with the hydraulic cylinder; the hydraulic cylinder is connected with the plier head through the connecting rod; and the plier head is arranged on the top of the plier body. The pair of multifunctional pliers is easy to manufacture and convenient to use, and can cut off steel bars, cables and high-voltage lines in rescue operations of earthquakes, traffic accidents, mine accidents and the like and can clamp heavy objects in cylindrical and other complicated shapes and the like. The force at the opening of the pliers is stabilized, the application range of the pliers is widened, and the aim of one pair of pliers and multiple purposes is fulfilled. The power of the pliers for breaking the barrier is provided in a hydraulic mode and not limited by the power supply, and the cutting force can be high. The dovetail groove at the opening of the pliers is of a replaceable type and is used for realizing the functions of clamping, shearing, expanding and the like, and the pair of multifunctional pliers is particularly suitable for shearing the steel bars which are unsuitable to be directly contacted in the disaster relief process.
Description
Technical field
The utility model relates to a kind of broken barrier and uses multifunctional pincer.
Background technology
Broken barrier instrument commonly used in the rescues such as earthquake at present,, traffic accident, mine disaster mainly contains diamond chain saw, cutting machine, circular saw, multifunctional hydraulic pincers etc.
Diamond chain saw cutting force is bigger, but volume is also bigger, and is power with gasoline, and consumption is arranged.
Cutting machine, the main drawback of circular saw have:
One, needs external power supply, be not suitable under powering-off state after the shake, using.
Heating during two, owing to cutting has personal injury in rescue.
Three, volume is bigger, can't use at small space.
The multifunctional hydraulic pincers adopt hydraulic power, and dispense with outer connecting power does not have power consumption, but owing to adopt the scissors principle, grasping part is little, and function is less, need the outer jack etc. of joining.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: provide a kind of and can overcome above-mentioned defective, the broken barrier of easy to use, applied range, nothing power consumption is used multifunctional pincer.
The utility model solves the technical scheme that its technical problem adopted: a kind of broken barrier is used multifunctional pincer; It is characterized in that comprise scissor handle, caliper, hydraulic gear and binding clip, hydraulic gear comprises plunger displacement pump, hydraulic cylinder and connecting rod; Plunger displacement pump is arranged on the inboard of scissor handle; Plunger displacement pump connects hydraulic cylinder, and hydraulic cylinder connects binding clip through connecting rod, and binding clip is arranged on the top of caliper.
Described plunger displacement pump connects hydraulic cylinder through reversal valve, and plunger displacement pump also is connected with fuel tank through check valve, and fuel tank is arranged on the caliper.
Described connecting rod comprises sector gear, idler gear and tooth bar, and the output shaft of hydraulic cylinder connects sector gear and forms crank rocker mechanism, and sector gear connects tooth bar through idler gear, and tooth bar connects binding clip.
Described binding clip comprises moving jaw and regular jaw, and moving jaw connects tooth bar, and the inboard of moving jaw and regular jaw is provided with dovetail groove, fixed shear cutter on the dovetail groove.
The beneficial effect that the utility model had is: makes simply, and easy to use, in rescues such as earthquake, traffic accident, mine disaster, cut off reinforcing bar, cable, high-tension bus-bar, all right clamping cylinder and other complex-shaped weights etc.The pliers scope of application that firmly enlarges of stablizing jaw realizes a pincers multipotency.The power of broken barrier pincers adopts hydraulic pressure to provide, and do not receive power limitations, and attainable cutting force is very big.Being designed to of jaw place dovetail groove is interchangeable,, shears purposes such as expansion, the shearing of the reinforcing bar that is particularly suitable for should not directly touching in the middle of the disaster relief process in order to realize clamping.
Description of drawings
Fig. 1 is the utility model structural representation;
1, scissor handle; 2, caliper; 3, plunger displacement pump; 4, hydraulic cylinder; 5, output shaft; 6, binding clip; 7, sector gear; 8, idler gear; 9, fuel tank; 10, regular jaw; 11, moving jaw; 12, reversal valve.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
Broken barrier as shown in Figure 1 is used multifunctional pincer; Comprise scissor handle 1, caliper 2, hydraulic gear and binding clip 6; Hydraulic gear comprises plunger displacement pump 3, hydraulic cylinder 4 and connecting rod, and plunger displacement pump 3 is arranged on the inboard of scissor handle 1, and plunger displacement pump 3 connects hydraulic cylinder 4; Hydraulic cylinder 4 connects binding clip through connecting rod, and binding clip is arranged on the top of caliper.Plunger displacement pump 3 connects hydraulic cylinder 4 through reversal valve 12, and plunger displacement pump 3 also is connected with fuel tank 9 through check valve 12, and fuel tank 9 is arranged on the caliper 2.Connecting rod comprises sector gear 7, idler gear 8 and tooth bar, and the output shaft of hydraulic cylinder 4 connects sector gear 7 and forms crank rocker mechanism, and sector gear 7 connects tooth bar through idler gear 8, and tooth bar connects binding clip.Binding clip comprises moving jaw 11 and regular jaw 10, and moving jaw 11 connects tooth bar, and the inboard of moving jaw 11 and regular jaw 10 is provided with dovetail groove, fixed shear cutter on the dovetail groove.
Extract reversal valve 12 during use; Scissor handle 1 compression plunger pump 3 provides pressure oil; Plunger displacement pump 3 also can provide pressure oil by fuel tank 9 through check valve, and pressure oil is injected into the output shaft that drives hydraulic cylinder 4 in the hydraulic cylinder 4 and drives sector gear 7 motions, and sector gear 7 drives 11 motions of rack drives moving jaw through idler gear 8; Moving jaw 11 cooperates with regular jaw 10 accomplishes holding function, cooperates the dissimilar shear knife of installation to accomplish functions such as clamping, shearing, expansion.After finishing using, press reversal valve 12, pull again and unclamp scissor handle 1, can unclamp jaw.
