Technical Field
The invention relates to the technical field of disassembling equipment, in particular to a counter-force support for replacing a coupler and a using method thereof.
Background
A coupling is a mechanical part used to connect two shafts in different mechanisms and rotate them together to transmit torque. Mechanical equipment is an important component in engineering, and is indispensable, and mechanical equipment with a coupling often plays an important role. The quality of the assembly quality of the coupling directly influences the normal operation of mechanical equipment. How to realize quick removal and replacement when the shaft coupling assembly has problems has a key influence on the normal operation of the whole system. In the process of disassembling the coupler, the connecting bolt is firstly disassembled, and then the shaft sleeve is disassembled from the rotating shaft. The shaft sleeve and the rotating shaft are in interference fit, and are difficult to disassemble in a conventional method.

and the jack is used for jacking between the base and the rotating shaft of the shaft coupling to be disassembled.
Furthermore, the pull rod is fixedly connected with the coupler through a bolt mounting hole in the shaft sleeve.
Furthermore, the pull rod penetrates through a bolt mounting hole in the shaft sleeve, and a nut is screwed at the free end of the pull rod.
Further, the jack is fixed on the base.
Further, the base is flat.
Further, the base is a steel plate with the thickness larger than 16 mm.
Furthermore, a plurality of through holes are formed in the base, and the pull rod is detachably connected with the base through the holes.
The invention also provides a use method of the counter force support for replacing the coupler, after the counter force support for replacing the coupler is fixedly connected with the coupler to be disassembled, the shaft sleeve is baked while the jack is jacked.
The counter-force support for replacing the coupler, provided by the invention, is simple to manufacture and convenient to use, the coupler dismounting efficiency is improved, a small amount of labor is invested, materials and tools in a construction site are utilized, the counter-force support is used in a matched manner, oxygen and acetylene are used for heating, the equipment can be ensured to be processed in time, the working efficiency is increased, and the counter-force support has extremely high popularization and utilization values.

In the figure, 1 is a base, 101 is a hole, 2 is a pull rod, 3 is a jack, 4 is a nut, 5 is a gasket, 6 is a shaft sleeve, and 7 is a rotating shaft.
Detailed Description
The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.
A counterforce bracket for coupling replacement, as shown in fig. 1, comprising:
a base 1;
the device comprises at least two pull rods 2 arranged on a base 1, wherein the free ends of the pull rods 2 are fixedly connected with a shaft sleeve 6 of a coupling to be disassembled;
and the jack 3 is used for jacking between the base 1 and the rotating shaft 7 of the coupler to be disassembled, and the telescopic direction of the jack 3 is consistent with the axial direction of the rotating shaft 7.
The using method comprises the following steps: after the counter-force support used for replacing the coupler is fixedly connected with the coupler to be disassembled, the shaft sleeve 6 is baked while the jack 3 is jacked. For guaranteeing the availability factor of this instrument, generally use with the oxygen rifle cooperation, the oxygen rifle toasts (evenly toast all around) counter shaft sleeve 6 at 3 jacking in-process of jack, according to the reason of the shrinkage that rises with heat, axle sleeve 6 during the rise with heat can the grow for pivot 7 and the positive tolerance grow of 6 cooperations of axle sleeve, can accelerate pivot 7 and the separation of axle sleeve 6 at 3 jacking in-process of jack.
The tool is simple to manufacture and convenient to use, improves the coupler dismounting efficiency, invests a small amount of labor, utilizes materials and tools of a construction site, is matched for use, is assisted with oxygen and acetylene for heating, can ensure that equipment is timely treated, increases the working efficiency, and has high popularization and utilization values.
The bolt mounting hole on the axle sleeve 6 can be used for fixed connection pull rod 2, specifically, pull rod 2 runs through the bolt mounting hole on the axle sleeve 6, has the nut 4 at the free end spiro union of pull rod 2, and the pad is equipped with gasket 5 between nut 4 and the axle sleeve 6.
The number of the pull rods 2 is at least two, and more pull rods 2 can be arranged for ensuring stability, for example, 6 bolt mounting holes are arranged on the shaft sleeve 6 in total, and then 6 pull rods 2 can be arranged.
In order to fix the jack 3 conveniently, the jack 3 can be fixed on the base 1.
The base 1 is flat and can be made of waste steel plates, so that the cost is saved, and the thickness of the base 1 is larger than 16mm for ensuring the structural strength.
The pull rod 2 is fixedly connected with the base 1, and the specific connection mode can be welding connection.
In order to adapt the counter force bracket for replacing the coupler to more specifications of shaft sleeves 6, the pull rod 2 and the base 1 are detachably connected, and the installation position of the pull rod 2 on the base 1 is changed according to the specification of the shaft sleeves 6. Specifically, in an optional implementation manner of this embodiment, as shown in fig. 2, a plurality of through holes 101 are formed in the base 1, the holes 101 are matched with bolt mounting holes on the shaft sleeve 6, and the pull rod 2 is detachably connected to the base 1 through the holes 101.
The scope of the invention is not limited thereto. The equivalent substitution or change made by the technical personnel in the technical field on the basis of the invention is all within the protection scope of the invention. The protection scope of the invention is subject to the claims.
