The utility model discloses the constitution includes: circular fixed bolster (2), circular fixed bolster be the disc structure, its central point puts and has the screw hole, the threaded hole in worn and to revolve top lead screw (1), top lead screw length be less than on-the-spot operable space, top lead screw left side be the square structure soon to round hole (6) have, top lead screw right-hand member face with fixed bolster right-hand member face flush, circular fixed bolster surface evenly distributed 3 slot holes (4), the slot hole in worn fixing bolt (5) respectively, back wheel (3) pass through fixing bolt and circular fixed bolster closely laminate. The utility model is used for the back wheel that uses in the little space pulls out the wheel.
Description
The technical field is as follows:
the utility model relates to a back wheel puller used in a small space.
Background art:
at present, when a short shaft is taken down and connected to a water pump (or a fan) and a motor to be connected and the backrest wheel is pulled out and removed, the position of the water pump (or the fan) and the motor needs to be moved to pull out and remove the backrest wheel of the water pump (or the fan) and the motor, the operation is time-consuming and labor-consuming, the working strength of pulling out and removing the backrest wheel is high, and the equipment rush-repair time is prolonged.
The utility model has the following contents:
the utility model aims at providing a back wheel puller used in a small space.
The above purpose is realized by the following technical scheme:
a back wheel puller used in a small space comprises: circular fixed bolster, characterized by: circular fixed bolster be the disc structure, its central point puts and has the screw hole, the screw hole in worn and to have the screw of screwing on, the screw left end outside of screwing on be the square, its inboard has the round hole, screw right-hand member face with fixed bolster right-hand member face flush, circular fixed bolster surface evenly distributed 3 slots, the slot in wear fixing bolt respectively, the back wheel passes through fixing bolt and circular fixed bolster closely laminate.
The fixing bolt comprises a bolt, the left end of the bolt is connected with the nut A through threads, and the right end of the bolt is connected with the gasket and the nut B through threads.
Has the advantages that:
1. the utility model relates to a back wheel puller that uses in the little space, the screw length of pushing up is less than on-the-spot operable space, when extracting and demolising the back wheel, need not to remove water pump (or fan), motor position, just can realize extracting fast and demolising the work to the back wheel of water pump (or fan) and motor, reduces working strength, saves equipment and salvages the time.
The utility model discloses a circular fixed bolster is disc structure, and its central point puts and has the screw hole, and threaded hole has worn the screw of revolving top, 3 slot holes or 4 evenly distributed symmetry slot holes of circular fixed bolster surface evenly distributed, (depending on the back wheel structure), has worn fixing bolt in the slot hole respectively, and the back wheel passes through fixing bolt and circular fixed bolster closely laminate, adopt this kind of structure can effectually make the back wheel and circular fixed bolster move on the screw of revolving top together, slot structure simultaneously, its purpose is according to back wheel type and size, and adjustment fixing bolt position is applicable to the back wheel of different structures and size, simple structure, and the flexibility is strong, the operation of being convenient for.
The utility model discloses a top screw left side is square structure to have the round hole, adopt this kind of structure can use big spanner to block the square, also can utilize the crowbar to insert the downthehole rotation that rotates of round hole simultaneously, the flexibility is strong, convenient to use.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of the circular fixing bracket of fig. 1.
The specific implementation mode is as follows:
example 1:
a back wheel puller used in a small space comprises: circular fixed bolster 2, circular fixed bolster be the disc structure, its central point puts and has the screw hole, the threaded hole in worn and to have the screw 1 of revolving top, screw length of revolving top be less than on-the-spot operable space, the screw left side of revolving top be the square structure to round hole 6 has, the screw right-hand member face of revolving top with fixed bolster right-hand member face flush, circular fixed bolster surface evenly distributed 3 or 4 slot holes 4, the slot hole in wear fixing bolt 5 respectively, back wheel 3 passes through fixing bolt and circular fixed bolster closely laminate.
Example 2:
according to the back wheel extractor used in the small space of the embodiment 1, the fixing bolt comprises a bolt 8, the left end of the bolt is connected with a nut A7 through threads, and the right end of the bolt is connected with a gasket 9 and a nut B10 through threads.
Example 3:
according to the back wheel pulling device used in the small space in the embodiment 1 or the embodiment 2, the circular fixing bracket is provided with long holes with the width of 15-20mm along the radial direction outwards by taking the circle center as a base point, 3-4 long holes are arranged according to the situation of the back wheel bolt hole, wherein the 3 long holes are horizontally arranged with the difference of 120 degrees, the 4 long holes are symmetrically arranged with the difference of 90 degrees, the thickness of the circular fixing bracket is 20mm (which can be increased according to the mechanical strength), and the center of the circular fixing bracket is provided with a threaded hole with the diameter of phi 35mm (which can be increased according to the mechanical strength).
The screw-top lead screw diameter be phi 35mm (can increase according to mechanical strength) screw lead screw, with the centre bore cooperation, screw-top lead screw length slightly be good at the back wheel and pivot contact mounting dimension, but want to be shorter than on-the-spot operable space, when the screw-top lead screw revolves to non-ejecting side, screw-top lead screw right-hand member flushes with circular fixed bolster or is a little higher than the support plane to the little space make full use of, the square structure is made to screw-top bolt afterbody, and open the round hole on the square structure, can block the square with big spanner and carry out the screw-top, also can utilize the rod to insert and carry out the screw-top in the round hole.
The diameter of the fixing bolt is smaller than the width of the long hole of the circular fixing support, the bolt penetrates through the backrest wheel bolt hole and the long hole of the circular fixing support, the left side of the circular fixing support is closed by a nut A, the exposed length is preferably the thickness of the nut, the gasket is matched with the backrest wheel side and then closed by a nut B and the bolt, and the circular fixing support and the backrest wheel are tightly combined and fixed together.
The concrete use method of the back wheel puller used in the small space comprises the steps of firstly enabling the right end part of the screw-top lead screw to be flush with or higher than the plane of the circular fixing support, then enabling the circular fixing support to be tightly combined and fixed with the back wheel by using a fixing bolt, using a large wrench to clamp a square structure at the left end of the screw-top lead screw to rotate, and also using a crowbar to be inserted into a round hole to rotate so as to slowly pull out the back wheel and enable the back wheel to be completely separated.
Claims (2)
