Example 1
The core of the utility model is to provide a quick shaft puller, which can avoid the problems of shaft slipping, shaft damage and safety accidents easily caused in the shaft pulling process by the structural design.
In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 and 2, fig. 1 is a schematic structural view of a shaft puller according to an embodiment of the present utility model, and fig. 2 is a left side view of fig. 1
The utility model provides a quick shaft puller, which comprises: the clamping plate, the tension rod 6, the tension hook 7 and the clamping plate connecting sleeve 3; the splint comprises: a cleat first part 8 and a cleat second part 9; the clamping plate locking teeth 5 are arranged at the contact position of the clamping plate second part 9 and the shaft, and the clamping plate connecting sleeve 3 is connected with the clamping plate center point through the clamping plate hinge point 4; the first clamping plate part 8 is hinged with one side, close to the end A, of the tension rod 6 through the clamping plate hinge point 2, and one side, close to the end B, of the tension rod 6 is hinged with the tension hook 7.
Further, the splint of the present utility model is integrally formed in a "V-shape" wherein the first portion 8 of the splint and the second portion 9 of the splint form an included angle of 120 degrees.
Further, the splint locking tooth 5 of the present utility model is serrated.
Furthermore, the shaft puller is made of Q235 steel, so that the structural strength of the shaft puller is ensured, and the shaft puller is prevented from being damaged due to the fact that the shaft puller cannot bear tensile force during shaft pulling.
In the prior art, when the shaft is pulled out, the hanging ring is welded on the end face of the shaft, the hand hoist is utilized to pull out the shaft, the welded hanging ring is cut off after the hand hoist is pulled out, and the welding point is polished by an angle grinder, so that the original appearance of the welding point is recovered. Therefore, the shaft can be damaged to a certain extent by adopting the traditional method, which is unfavorable for the recovery and installation of the shaft and influences the matching quality of the shaft.
In order to ensure that the shaft is not damaged when the shaft is pulled out, the clamping plate locking teeth 5 are made of anti-skid rubber. Therefore, when the shaft is pulled out, the clamping plate locking teeth 5 cannot damage the surface of the shaft when clamping the shaft.
In the prior art, a pipe wrench is used for clamping a shaft, the shaft is a cylinder, the surface friction force is small, the phenomenon of slipping occurs when a steel wire rope or a hanging ring is used, and then a crowbar is added for prying, so that the shaft slowly rotates out. Therefore, the shaft can slip when the shaft is pulled out by adopting the traditional method, and once the shaft slips, accidents such as personal injury and mechanical injury to surrounding personnel or operators are easily caused.
In order to ensure that the clamping plate is not easy to slip off when the shaft is pulled out, the clamping plate locking teeth 5 are made of anti-slip rubber, and the clamping plate second part 9 is designed to be in an arc shape capable of being attached to the shaft. Therefore, the shaft can be better clamped when the shaft is pulled out by the structural design of the utility model, and the slipping of the shaft can not be caused.
In order to prevent injury to peripheral personnel or operators in the shaft pulling process, the clamping plates are symmetrically arranged in pairs, at least two groups of clamping plates are arranged, and the clamping plates and the shaft are in encircling type design; the clamping plate connecting sleeve 3 is designed in an annular mode, and the clamping plate connecting sleeve 3 is made of rubber and has ductility and can be suitable for shaft sleeving of different shaft diameters. Therefore, through such design, when the slippage or fracture condition appears when pulling out the axle, splint adapter sleeve 3 can entangle the axle, lets the axle can not get rid of and fly to peripheral personnel to splint and the design that the axle becomes the encircling formula and also can guarantee that the axle gets rid of when flying, can not produce the injury to the operator of pulling force hook one side.
It should be noted that in this embodiment, when the shaft puller is used, an operator is required to sleeve the shaft from the end B to the end a, and the shaft puller can be easily sleeved along the shaft due to the arc-shaped design of the second part of the clamping plate, and then the shaft puller stops after reaching a proper position, wherein the shaft is directly penetrated through the clamping plate connecting sleeve 3 when the shaft is sleeved due to the annular design of the clamping plate connecting sleeve 3, and the shaft can be quickly aligned without manual assistance. The operator exerts AB-direction force on the tension hook 7, the clamping plate also generates AB-direction force, and under the action of the clamping plate hinge points 2 and 4, the clamping plate locking teeth generate radial force towards the center of the shaft, so that the effect of rapidly and stably pulling the shaft is achieved.
Further, the generated radial force, namely friction force, is determined by the tensile force, and the larger the tensile force is, the larger the friction force is, so that the phenomenon of slipping caused by overlarge tensile force can be avoided.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
While the foregoing description of the embodiments of the present utility model has been presented in conjunction with the drawings, it should be understood that it is not intended to limit the scope of the utility model, but rather, it is intended to cover all modifications or variations within the scope of the utility model as defined by the claims of the present utility model.
