Abstract

The utility model relates to a jaw type hydraulic puller, specifically a kind of jaw fixing structure of the hydraulic puller. A kind of jaw structure for hydraulic puller comprises a fixing mechanism and a jaw which is arranged on the fixing mechanism. The fixing mechanism is composed of a fixing block, a jaw bracket, a spring and a spring pallet. The end surface of the jaw presents a flat shape, and is appressed with the upper surface of the jaw bracket. A spring is arranged between the lower surface of the jaw bracket and the upper end surface of the spring pallet. The utility model has the advantages of simple structure, convenient jaw disassembly, and simple operation.

Description

A kind of hydraulic pressure draws the pawl structure of horse

The hydraulic pressure that the utility model relates to a kind of pawl formula draws horse, is a kind of pawl fixed sturcture that hydraulic pressure draws horse specifically.

Existing hydraulic pressure draws the pawl structure of horse very simple on the market, be directly installed on the pawl reaction plate, during operation, a people is fixed on three pawls and is drawn on the thing, and another people then rotates threaded shaft, after fixing, can people's independent operation, whole process is as by one man operation, and three pawls are independent separately, often can't be fixed on simultaneously and be drawn on the thing, use very inconvenience; It is to immobilize that hydraulic pressure draws the pawl length of horse, or shirks extremely inconvenience, is drawn thing too big or oversize, then can't use.

The purpose of this utility model is to provide that a kind of simple in structure, pawl shirks conveniently, a kind of hydraulic pressure simple to operate draws the pawl structure of horse.

The purpose of this utility model is achieved like this, a kind of hydraulic pressure draws the pawl structure of horse, comprise fixed mechanism and the pawl that is installed on the fixed mechanism, the characteristics of this pawl structure are: fixed mechanism is made up of fixed block, pawl carriage, spring, spring tray, the end face of pawl is planar shaped, is close to pawl carriage upper surface, and a spring is arranged between pawl carriage lower surface and the spring tray upper surface, spring application pawl carriage, the pawl carriage compresses the pawl end face.

There is a shaft shoulder fixed block lower end, this shaft shoulder external diameter cooperates with the internal diameter of pawl carriage, the internal diameter of spring tray respectively, jump ring is close in the spring tray lower surface, and jump ring is fixed on fixed block shaft shoulder end, and spring tray, pawl carriage and spring are clamped on the shaft shoulder of fixed block.

Fixed block has some U type vertical slots radially, and position, a hole is all arranged on the vertical slot wall, and there is a through hole in radix unguis portion, and each radix unguis portion is fixed in each U type vertical slot by some pins.

The utlity model has following advantage:, be close to pawl carriage upper surface, under the spring force effect because the end face of pawl is planar shaped, the folding simultaneously of each pawl, behind moving one or two pawl of plate, all the other pawls are folding automatically simultaneously, can independently use by a people, easy to operate; Each pawl is fixed on fixed block by some pins some U type vertical slots radially, as long as transfer to each pin, with regard to the different pawl of replaceable length, has improved the range of use that draws horse widely.

Below in conjunction with drawings and Examples the utility model is done step detailed description.

Fig. 1 is the front view of the utility model embodiment

Fig. 2 is the front view of the utility model fixed block

As shown in Figure 1, 2, fixed block 1 has three U type grooves, and three grooves are along the circumference rectangular distribution and leave certain wall thickness, remainder is emptied, on each U type cell wall a through hole is arranged, the root of pawl 2 also has a through hole, and pin 3 can turnover freely in two cell wall through holes and pawl 2 root through holes like this.After integral installation finishes, pawl 2 end face spring-loadeds, simultaneously pin 3 also is subjected to the diametral load effect, can easily not come off, certainly, in order to guarantee sound construction, also can be in pin 3 ends or other position establish the groove chucking.When shirking pawl 2, need press pawl carriage 4, compression spring 5, at this moment, pin 3 not spring-loadeds are conveniently shirked.

Among Fig. 1, pawl carriage 4 upper surfaces are inclined-planes, and pawl 2 end faces and this inclined-plane are close to, and pawl 2 is slightly-inclined.Pawl carriage 4 has the shaft shoulder of certain-length, with mounting spring 5, be close to spring tray 6 and jump ring 7 below the spring 5, there is a shaft shoulder fixed block 1 lower end, this shaft shoulder external diameter cooperates with the internal diameter of pawl carriage 4, the internal diameter of spring tray 6 respectively, jump ring 7 is close in spring tray 6 lower surfaces, and jump ring 7 is fixed on fixed block 1 shaft shoulder end, and spring tray 6, pawl carriage 4 and spring 5 are clamped on the shaft shoulder of fixed block 1.
