Abstract
The utility model relates to a hydraulic screw extractor, which comprises an oil cylinder, a back screw support, a link rod, a fixing screw, a knockout pin and three extraction grippers. One end of the extraction grippers is in pin joint with the back screw support through the link rod. The back screw support is connected with the fixing screw with the knockout pin on the front end through thread. The tail end of the fixing screw is in pin joint with the oil cylinder. The utility model is characterized in that regulation and control link rods are arranged at the bent elbows of the extraction grippers, which are in pin joint with the bent elbows; the other ends of the regulation and control link rods are in pin joint with a link rod sliding disk sheathed on the fixing screw. The front end face of the link rod sliding disk contacts and is connected with a front nut connected with the fixing screw through thread. The utility model has the advantages that the opening and closing degree of the extraction grippers can be adjusted according to the diameters of the components to be extracted; the extraction grippers do not slide down from the components exacted easily; the hydraulic screw extractor can be operated by one man. Operators are reduced by one or two operators during the operation; and the productive man hour is saved. The hydraulic screw extractor can be promoted as a universal product, which can bring certain social benefits.
Description
Technical field
The utility model belongs to the horse of drawing of electromechanical equipment maintenance usefulness, relates in particular to a kind of hydraulic pressure that can save manpower, adjustable synchronous opening and closing pulling claw and draws horse.
Background technology
Dynamo-electric maintenance company all will dismantle the parts such as bearing, shaft joint, ship driving wheel at electromechanical equipment transmission position every day.It is the essential tool of dismounting part that hydraulic pressure draws horse.The hydraulic pressure that uses draws the horse structure to be made up of oil cylinder, back screw support, connecting rod, standing screw, push rod and three pulling claws at present, described pulling claw one end is by connecting rod and back screw support pin joint, the standing screw that back screw support and front end are provided with push rod is spirally connected, and the standing screw tail end is connected with oil cylinder.This structure exists the problem of inconvenient frequent operation.During operation, generally need two people to carry out simultaneously, a people holds up pulling claw, the one man operation oil cylinder.The shortcoming that also exists is simultaneously: the diameter range that is suitable for is little; Pulling claw opening and closing synchronously, every operation once all will be drawn on the object by manually pulling claw being positioned at, and it is set upright, and carry out hydraulic operation by another person then, treat push rod and object drawn stressed after, manually just can break away from pulling claw, very inconvenient.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provide a kind of and can regulate and control, the hydraulic pressure of opening and closing pulling claw draws horse synchronously, has fundamentally solved time-consuming, effort, inefficient shortcoming.
The utility model for achieving the above object, by the following technical solutions: a kind of hydraulic pressure draws horse, by oil cylinder, back screw support, connecting rod, standing screw, push rod and three pulling claws are formed, described pulling claw one end is by connecting rod and back screw support pin joint, the standing screw that back screw support and front end are provided with push rod is spirally connected, the standing screw tail end is connected with oil cylinder, it is characterized in that: described pulling claw curved boom elbow place is provided with the regulation and control connecting rod with its pin joint, the described regulation and control connecting rod other end touches with the preceding nut that is screwed onto on the standing screw with the connecting rod slider disc pin joint that is socketed on the standing screw, connecting rod slider disc front end face.
Articulate spring on the screw support of described back, the spring other end and last pulling claw articulate.
The beneficial effects of the utility model: pulling claw can be adjusted its opening and closing degree according to the diameter that is drawn part; Pulling claw is difficult for from being drawn landing on the part; Can the one man operation.In operating process, reduce 1-2 name operative employee and saved production man-hour.Can be used as universal product promotion, have the certain social benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing:
As shown in the figure, a kind of hydraulic pressure draws horse, form by operating grip 11, oil cylinder 10, back screw support 9, connecting rod 8, standing screw 3, push rod 2 and three pulling claws 1, described pulling claw one end is by connecting rod and back screw support pin joint, the standing screw that back screw support and front end are provided with push rod is spirally connected, the standing screw tail end is connected with oil cylinder, described pulling claw curved boom elbow place is provided with the regulation and control connecting rod 5 with its pin joint, the described regulation and control connecting rod other end touches with the preceding nut 4 that is screwed onto on the standing screw with connecting rod slider disc 7 pin joints that are socketed on the standing screw, connecting rod slider disc front end face.Articulate spring 6 on the described back screw support, the spring other end and pulling claw wherein a last pulling claw articulate, and can overcome the gravity of pulling claw.Utilize shape, size, the structure of pulling claw better to hold and be disassembled part.The structure of screw, connecting rod slider disc, regulation and control connecting rod can be adjusted pulling claw folding size arbitrarily synchronously before utilizing.Structural principle: in the appropriate location of three pulling claws, set up three regulation and control strong points, and be connected, adjust the advance and retreat of this connecting rod slider disc, can control the synchronous opening and closing of three pulling claws by preceding screw with the connecting rod slider disc that is installed at the oil cylinder front end.
The above only is preferred embodiment of the present utility model, is not its structure is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1, a kind of hydraulic pressure draws horse, form by oil cylinder, back screw support, connecting rod, standing screw, push rod and three pulling claws, described pulling claw one end is by connecting rod and back screw support pin joint, the standing screw that back screw support and front end are provided with push rod is spirally connected, the standing screw tail end is connected with oil cylinder, it is characterized in that: described pulling claw curved boom elbow place is provided with the regulation and control connecting rod with its pin joint, the described regulation and control connecting rod other end touches with the preceding nut that is screwed onto on the standing screw with the connecting rod slider disc pin joint that is socketed on the standing screw, connecting rod slider disc front end face.
