Abstract
The utility model relates to a heavy tong which comprises a screw rod, a cross arm and two pull claws, wherein an external thread is arranged on a surface of the screw rod; a threaded hole is formed at the center of the cross arm; the end parts of each of the pull claws are provided with claw corners; the screw rod is screwed into the threaded hole; the cross arm is integrally formed with the pull claws; the claw corners of the pull claws are vertical to the screw rod mutually; and slope transition is adopted on two sides of the cross arm. Compared with the prior art, the heavy tong has the advantages that the structure is simple, convenience and safety of use are achieved, the claw corners are vertical to the screw rod to effectively prevent a falling phenomenon, the cross arm is integrally formed with the pull claws, the stress resistance of the whole heavy tong is enhanced and the heavy tong can adapt to the stress with higher strength.
Description
Technical field
The utility model relates to a kind of instrument from axle dismounting assembling parts, relates in particular to a kind of heavy type and draws horse.
Background technology
During from axle dismounting bearing, to use a kind of specific purpose tool that draws horse that is called usually, claim again and existingly draw horse to be mostly pawl Shi Lama, mainly comprise screw mandrel, transverse arm and pulling claw; During use, pulling claw is buckled on the outer rim of bearing, with screw mandrel withstand the axle end face, rotary screw rod can spur bearing.The main defective that exists is: 1, in unloading process, because the angle at pulling claw pawl angle is spent less than 90, pulling claw comes off easily; 2, transverse arm and pulling claw are not one-body molded, and when excessive, transverse arm and pulling claw easy separation are broken off when stressed.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that prior art exists, and provides a kind of stability high, receives the big heavy type of force intensity to draw horse.
The purpose of the utility model realizes through following technical scheme: comprise that the surface is provided with externally threaded screw mandrel, central authorities and offers the transverse arm of screwed hole and the pulling claw that two ends have the pawl angle; Said screw mandrel screws in the screwed hole, and said transverse arm and pulling claw are one-body molded; The pawl angle of said pulling claw is vertical each other with said screw mandrel.
The slope transition is adopted in the said transverse arm of the utility model both sides.
The beneficial effect of the utility model is: compared with prior art, it simple in structure, safe and convenient to use, the pawl angle is vertical with screw mandrel, has effectively prevented obscission; Transverse arm and pulling claw are one-body molded, have strengthened whole anti-hard power ability of drawing horse, therefore can adapt to more high-intensity stressed.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: as shown in Figure 1, comprise that screw mandrel 1, central authorities that the surface is provided with external screw thread 4 offer the transverse arm 2 of screwed hole 5 and the pulling claw 3 that two its ends have pawl angle 6; Said screw mandrel 1 screws in the screwed hole 5, it is characterized in that: said transverse arm 2 is one-body molded with pulling claw 3; The pawl angle of said pulling claw 3 is vertical each other with said screw mandrel 1.
Said transverse arm and pulling claw combine not to be provided with reinforcement.
Specific operation process is: at first according to the size of the parts of required dismounting, rotary screw is buckled in pulling claw on the dismounting parts to certain position then, and rotary screw rod withstands the dismounting parts once more, and rotates till removing parts always.Because the pawl angle is vertical with screw mandrel, so the pawl angle firmly must fasten the dismounting parts, obscission can not take place; Transverse arm and pulling claw are one-body molded, and adopt the slope mistake, reduced pulling claw in loading process to the vertical direction component of transverse arm, reduced damage to transverse arm; The reinforcement that is arranged between transverse arm and the pulling claw also can play a protective role.
Certainly, above-mentioned explanation is not the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the scope of the utility model, the variation of making, change and add or replacement, all should belong to the protection domain of the utility model.
Claims (2)
1. a heavy type is drawn horse, comprises that the surface is provided with the screw mandrel of external screw thread (4) (1), central authorities and offers the transverse arm (2) of screwed hole (5) and the pulling claw (3) that two its ends have pawl angle (6); Said screw mandrel (1) screws in the screwed hole (5), it is characterized in that: said transverse arm (2) is one-body molded with pulling claw (3); The pawl angle of said pulling claw (3) is vertical each other with said screw mandrel (1).
2. heavy type according to claim 1 is drawn horse, it is characterized in that: slope (7) transition is adopted in said transverse arm (2) both sides.
