Abstract

The utility model discloses a hydraulic nut splitter, comprising a working head; the working head is provided with a cutting hole for containing a nut; the wall of the cutting hole is provided with a through hole which is internally provided with a push rod in a sliding manner; one end of the push rod, close to the cutting hole, is detachably provided with a cutter, and the other end thereof is arranged on a piston of a hydraulic cylinder which is fixedly connected with the working head; and a reset spring is arranged between the piston and the working head. The hydraulic nut splitter has small volume, convenient operation and good working performance, can adopt manual hydraulic power equipment respectively under the conditions of high altitude, other spaces with limited manpower, sites without power supply and the like, has strong cutting capability, cuts the nut with high speed and fast cutting without damage to a screw, does not generate spark, is safe and is applicable to various fireproof and explosion-proof fields.

Description

The fluid pressure type nut device of riving

Technical field

The utility model relates to and a kind of the nut that spanner can't be blocked because of corrosion, modification is broken the special tool(s) of cutting dismounting, is applicable to that especially oil well head device etc. does not allow with the device of riving of the fluid pressure type nut under the working condition of fiery electricity consumption.

Background technology

At present, in various plant equipment, be extensive use of screw bolt and nut and fix plant equipment, owing to various reasons such as corrosion, burn into modification, cause nut not quick detachable, consuming time, effort, sometimes even can not dismantle, make troubles for the maintenance, replacing etc. of equipment, when serious some work is stagnated.

The utility model content

The purpose of this utility model is: nut is difficult for or non-detachable problem in order to solve, provide a kind of and fast and efficiently nut cut off, and do not damage screw rod, the fluid pressure type nut of safety is rived device.

The technical solution of the utility model is:

A kind of fluid pressure type nut device of riving, include working head, a shearing perforation that holds nut is arranged on the working head, on the shearing hole wall, a through hole is arranged, push rod slidably is installed in the through hole, and push rod removably is equipped with cutting knife near on the end of shearing perforation, and the other end is installed on the piston of hydraulic jack, hydraulic jack is fixedlyed connected with working head, between piston and working head back-moving spring is installed.

Supplementary technology scheme of the present utility model is as follows:

Above-mentioned push rod and piston are a global facility.

Above-mentioned working head tail end has external screw thread, and the hydraulic jack front end has internal thread, and the two is assembled together by screw thread.

The oil connection that is communicated with in-line is arranged on the above-mentioned hydraulic jack, be connected with hydraulic power system fast.

Working method of the present utility model: at first the blade peace that is fit to be cut the nut size is stuck on the push rod, again hydraulic jack is connected with hydraulic power system, the device working head of riving is enclosed within on the nut that needs to shear, the operation hydraulic power system, pressurization produces broken shear force to nut thereby promote piston by hydraulic jack, is rived fully until nut.

The beneficial effects of the utility model are: volume is little, easy to operate, favorable working performance, under conditions such as other limited space of high-altitude, manpower, on-the-spot non-transformer, all can adopt manual hydraulic power unit, the broken ability of cutting is strong, nut is cut off at a high speed, soon with cutting, and do not damage screw rod, can not produce spark, safety is applicable to various fire prevention, explosion-proof field.

Description of drawings

The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:

Fig. 1 is the rive overall structure schematic diagram of device embodiment of this fluid pressure type nut.

Fig. 2 is the fluid pressure type nut shown in Figure 1 whole release principle schematic of device of riving.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Specific embodiment of the utility model, a kind of fluid pressure type nut device of riving as shown in Figure 1, includes parts such as working head 1, hydraulic jack 4, push rod 7, cutting knife 3.Wherein, a shearing perforation that holds nut 2 is arranged on the working head 1, on the shearing hole wall, a through hole is arranged, push rod 7 slidably is installed in the through hole, push rod 7 removably is equipped with cutting knife 3 near on the end of shearing perforation, the other end is installed on the piston of hydraulic jack 4, push rod 7 also can be to make integrally formed parts with piston, working head 1 tail end has external screw thread, hydraulic jack 4 front ends have internal thread, the two is assembled together by screw thread, and back-moving spring 6 is installed between piston and working head.The oil connection 5 that is communicated with in-line is arranged on the cylinder body of hydraulic jack 4, conveniently be connected with hydraulic power system.

When the fluid pressure type nut of present embodiment is rived the device use, at first measure the specification of nut 2, choose cutting knife 3 peaces of mating and be stuck on the push rod 7 with this nut 2.Oil pipe with oil connection 5 and hydraulic means is connected then.Then the working head of the device of riving being enclosed within needs on the broken nut of cutting 2, opening hydraulic means makes hydraulic oil enter hydraulic fluid chamber 8 promotion pistons and push rod along Fig. 1 arrow direction by oil pipe to oil connection, make cutting knife 3 to nut 2 motions, and press to nut 2 gradually, and strength is increasing, is broken fully until nut 2.Pressure-relief valve on the last operation hydraulic means is laid down the pressure in the hydraulic jack oil pocket 8, and push rod 7 and piston return to the preceding original position of work in the motion of direction shown in Fig. 2 arrow of the tension force effect lower edge of spring 6.Take off the device of riving, realize the nut excision.

Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.

Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
