Abstract
The invention relates to a hand-held hydraulic expander which is mainly composed of an expansion arm, sharp raised heads, a hydraulic device and a top handle, wherein the expansion arm is composed of an upper sharp arm and a lower sharp arm, a semicircular curved dome is arranged at the rear part of each sharp arm, and a groove is formed in the inner side of each curved dome; the hydraulic device comprises a hydraulic cylinder, hydraulic rods and a hydraulic crank handle, and the hydraulic rods are connected with the sharp raised heads in the curved domes; groove bumps are arranged on the sharp raised heads and can slide on the grooves of the curved domes in a buckled manner; the top handle and the hydraulic cylinder are connected to the aftermost part. The hand-held hydraulic expander is simple in structure, and an operator only needs to insert the expansion arm into an expansion part and the operator can carry out hand expansion action. The hand-held hydraulic expander can be convenient for people to push in the expansion process so as to prevent slip, thereby achieving the purpose of safe expansion.
Description
Technical field
The present invention relates to a kind of portable expansion barrier-breaking device, be specifically related to a kind of hand hydraulic spreader, belong to Mechanical Industry Technology field.
Background technology
In emergency episode, if waste the cost of a few second with regard to likely giving one's life for, and hydraulic dilatation device is used to indicator of trapped personnel to save out in time from damage vehicle.Indicator of trapped personnel also can save out by such device after earthquake from the reinforced concrete structure collapsed.Hydraulic spreader is used for parts to strut, or fills in vehicle interior certain part is torn.Existing expander is all the sharp mouth inserted into gap expander, then stress on both hands handle of stopping to carry out rocking from side to side and carry out hydraulic dilatation, but because two hands all will be used for rocking handle, unclamp motive force forward, expansion process in can occur retrolisthesis from, by expansion body again bullet close back the situation of original position, bullet closes back in the process of original position likely can carry out secondary injury to by the personnel clamped.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, provide a kind of portable hydraulic extension fixture, its structure is simple, easy to use, and the scope of application is extensive, and reliability is high, and wearability is good, can clamp, lightweight, is easy to carry.
For achieving the above object, the technical solution used in the present invention is: hand-held hydraulic spreader is formed primarily of expansion arm, sharp protruding head, hydraulic means, top handle, and described expansion arm has the pointed arm of half corner bevelling vault to form by upper and lower two rear portions, has groove inside curved vault; Described hydraulic means comprises hydraulic cylinder, hydraulic stem, hydraulic pressure wind, and hydraulic stem is connected with the sharp protruding head in curved vault, sharp protruding head has groove dash forward and can do to engage to slide with the groove on curved vault, and top handle and hydraulic cylinder are connected to rearmost part.
Hand-held hydraulic spreader is that employing hydraulic means promotes a sharp protruding head and expands two expansion arm, and two expansion arm are expanded again, carries out a point expansion to expanded object.Because the hydraulic cylinder in hydraulic means is vertical with the direction of expansion, hydraulic cylinder also makes the part connection handle body of expander.Hydraulic stem in hydraulic cylinder and a sharp protruding head in aggregates, the propelling of point protruding head directly can be expanded two expansion arm, during hydraulic stem retraction, point protruding head also bounces back, two expansion arm also should bounce back merging, this merging can have been come by spring, but the space between two expansion arm has been the activity space of sharp protruding head, does not have space spring.In order to address this problem, we to advance by leaps and bounds row clamping at the curved vault inside groove of sharp protruding head and expansion arm and groove, this clamping close make sharp protruding head can not expansion arm separately, two expansion arm can only be expanded and retracting action along with the movable of sharp protruding head.
In line, therefore, we are arranged on rear portion hydraulic pressure wind, and hydraulic pressure wind trends towards vertical with hydraulic push rod, are user-friendly for hand expansion like this for hydraulic cylinder in hand-held hydraulic spreader and direction of propulsion.One of support on hand-held hydraulic spreader is top handle, top handle is bent into the direction vertical with direction of propulsion after being connected with hydraulic cylinder rear portion, such people can shake expansion on the other hand, and another hand can also catch push rod to fix, and can also do auxiliary ejection with arm.
The beneficial effect of hand-held hydraulic spreader is: hand-held hydraulic spreader structure is simple, expansion arm only need be inserted expansion position by operating personnel can carry out hand expansion action, and people can be facilitated in the process of expansion to do ejection, in case on-slip takes off, reach the object of safety expansion.
Accompanying drawing explanation
Fig. 1 is the side appearance perspective view of hand-held hydraulic spreader.
In figure: 1-expansion arm; 2-bearing pin; 3-expansion arm support; 4-hydraulic cylinder; 5-hydraulic stem; The curved vault of 6-; 7-point protruding head; 8-groove; 9-hydraulic pressure wind; 10-pushes up handle.
Detailed description of the invention
below in conjunction with accompanying drawing, further implementation is done to hand-held hydraulic spreader.
Fig. 1 shows that leader holds the integral vertical body structure side view of hydraulic spreader, two expansion arm about 1 in figure each one involutory, afterbody is connected with expansion arm support 3 with bearing pin 2, can carry out the activity of opening and closing.Described expansion arm support 3 is fixed on outside hydraulic cylinder 4, and hydraulic stem 5 front end of stretching out in described hydraulic cylinder 4 is provided with sharp protruding head 7, and sharp protruding head 7 is placed in the curved vault 6 at two expansion arm 1 rear portions.Groove in point protruding head 7 is dashed forward and to be engaged with the groove hook 8 inside curved vault 6 and can slide, so sharp protruding head 7 is movable by the expansion of promotion two expansion arm 1 or closed, and the movement of sharp protruding head 7 pushes away by hydraulic stem 5 control of contracting.Liquid in figure is taken cylinder 4 by force and is not only made hydraulic means but also connect the effect of fixing support handle, and the hydraulic pressure wind 9 after hydraulic cylinder 4 does vertical setting, and very convenient people carries out shake supercharging.The top handle 10 at rear portion is also done curvedly vertically to arrange by the bar bent, and people can withstand this top handle 10 with arm, with anti-slip generations accident in the process of shake expansion.
