To achieve these goals; The utility model provide a kind of be used for the dismounting belt pulley draw the horse assembly; Said belt pulley is sleeved on the axle, wherein, said draw the horse assembly to comprise backing plate and have motion bar and a plurality of bluff pieces draw horse; One end of said motion bar is resisted against an end of said axle, and said a plurality of bluff pieces are around said belt pulley setting and can said backing plate be pressed against on the end face of said belt pulley.
Preferably, the area of said backing plate equates with the area of the end face of said belt pulley.
Preferably, said backing plate is an annular.
Preferably, said backing plate comprises the steel plate of two identical fan annulars.
Preferably, saidly draw horse to comprise three bluff pieces.
Preferably, saidly draw horse to comprise connector, said three bluff pieces are connected with said motion bar through said connector, and said motion bar can move with respect to said connector.
Preferably, saidly draw horse to comprise the linking arm corresponding with said bluff piece, the two ends of this linking arm are hinged with said bluff piece and said connector respectively.
Through technique scheme, owing between bluff piece that draws horse and belt pulley, backing plate is set, thus in disassembly process, increased the lifting surface area of belt pulley, make it stressed evenly, be difficult for belt pulley is caused fracture damage, guaranteed the normal operation of motor.Wherein, draw the Marko to adopt the horse of drawing of various models, structure, for example Three-claw pull-horse, two pawls draw horse and hydraulic pressure to draw horse etc., as long as can all can from axle dismounting belt pulley.
Other feature and advantage of the utility model will partly specify in the specific embodiment subsequently.

The specific embodiment
Be elaborated below in conjunction with the specific embodiment of accompanying drawing to the utility model.Should be understood that the specific embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
As depicted in figs. 1 and 2; The specific embodiment of the utility model provide a kind of be used for the dismounting belt pulley draw the horse assembly; Said belt pulley 1 is sleeved on the axle 2, wherein, said draw the horse assembly to comprise backing plate 3 and have motion bar 41 and a plurality of bluff pieces 42 draw horse 4; One end of said motion bar 41 is resisted against an end of said axle 2, and said a plurality of bluff pieces 42 are provided with and can said backing plate 3 be pressed against on the end face of said belt pulley 1 around said belt pulley 1.
Owing between the tip of the bluff piece that draws horse 4 42 and belt pulley 1, backing plate 3 is set, thereby in disassembly process, has increased the lifting surface area of belt pulley 1, make it stressed evenly, be difficult for belt pulley 1 is caused fracture damage, guaranteed the normal operation of motor.Wherein, draw horse 4 can adopt the horse of drawing of various models, structure, for example Three-claw pull-horse, two pawls draw horse and hydraulic pressure to draw horse etc., as long as can all can from axle 2 dismounting belt pulleys 1.
As shown in Figures 2 and 3, stable for the clamping of 42 pairs of backing plates 3 of bluff piece of guaranteeing to draw horse 4, preferably, the area of said backing plate 3 equates with the area of the end face of said belt pulley 1.Usually; The area of backing plate 3 basically equates with the area of the end face of belt pulley 1; Perhaps be slightly larger than the area of the end face of belt pulley 1, thereby the tip of bluff piece 42 contacts directly with backing plate 3, and then backing plate 3 is given belt pulley 1 with force transmission and is dismantled; Guarantee belt pulley 1 end face stressed evenly, avoid causing the edge of belt pulley 1 impaired.
Like Fig. 1 (b) and shown in Figure 4, the installation of backing plate 3 and setting for ease, preferably, said backing plate 3 is an annular.The internal diameter of the backing plate 3 of annular can be slightly larger than the diameter of axle 2, thereby backing plate 3 can easily be sleeved on the axle 2.Backing plate 3 can adopt various materials to process, when adopting flexible material, processes by backing plate 3, and for example rubber, plastics etc., the diameter of backing plate 3 can equal the diameter of axle 2, even is slightly less than the diameter of axle 2, still can backing plate 3 covers be installed on the axle 2.
Shown in Fig. 1 (b), in order to strengthen the force intensity that receives of backing plate 3, preferably, said backing plate 3 comprises the steel plate of two identical fan annulars.Adopt steel plate to make backing plate 3, thus backing plate 3 receive force intensity higher, not fragile.Installation of backing plate 3 for ease and increase lifting surface area, backing plate 3 is formed by the steel plates of two identical fan annulars, and both cooperate the formation annular to be installed on the axle 2.
Shown in Fig. 1 (a), preferably, saidly draw horse 4 to comprise three bluff pieces 42.According to the stable principle of triangular structure, draw horse 4 to adopt Three-claw pull-horse, three bluff pieces 42 form three stress points with backing plate 3 clampings, to guarantee the stability under loading of belt pulley.
Shown in Fig. 1 (a); The motion of motion bar 41 for ease and belt pulley 1 is applied pulling force preferably, saidly draws horse 4 to comprise connector 43; Said three bluff pieces 42 are connected with said motion bar 41 through said connector 43, and said motion bar 41 can be with respect to said connector 43 motions.Motion bar 41 is exerted pressure to an end of axle 2 with respect to connector 43 motions, thereby 42 pairs of belt pulleys of the bluff piece that is connected with connector 43 1 produce pulling force, to dismantle belt pulleys 1 from axle 2.
The position of bluff piece 42 adjustment for ease is to adapt to difform belt pulley 1; Shown in Fig. 1 (a); Preferably, saidly draw horse 4 to comprise the linking arm 44 corresponding with said bluff piece 42, the two ends of this linking arm 44 are hinged with said connector 43 with said bluff piece 42 respectively.Because the two ends of linking arm 44 are hinged on respectively on bluff piece 42 and the connector 43, thereby bluff piece 42 can be free movable, with the belt pulley 1 that adapts to different-diameter it is clamped between the bluff piece 42, makes and draw the practicality of horse 4 stronger, and range of application is wider.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But; The utility model is not limited to the detail in the above-mentioned embodiment; In the technical conceive scope of the utility model, can carry out multiple simple variant to the technical scheme of the utility model, these simple variant all belong to the protection domain of the utility model.
Need to prove in addition; Each concrete technical characterictic described in the above-mentioned specific embodiment under reconcilable situation, can make up through any suitable manner; For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible compound modes.
In addition, also can carry out combination in any between the various embodiment of the utility model, as long as its thought without prejudice to the utility model, it should be regarded as content disclosed in the utility model equally.
