Detailed Description
As shown in fig. 1 to 4, a shaft sleeve dismounting tool of an asphalt concrete paver comprises a pushing device 2; the pushing device 2 comprises a threaded push rod 2-1, a connecting shell 2-2, a pressure bearing 2-4, a bottom plate 2-7 and two connecting bolts I2-3; the front end of the threaded push rod 2-1 is provided with a pressure bearing 2-4, the outer ring of the front end of the pressure bearing 2-4 is detachably provided with a bottom plate 2-7, the threaded push rod 2-1 is installed on the connecting shell 2-2 in a threaded mode, the threaded push rod 2-1 is held by hand, the connecting shell 2-2, the pressure bearing 2-4 and the bottom plate 2-7 enter the shaft sleeve 1, the bottom plate 2-7 is abutted against the auger shaft, the outer end of the shaft sleeve 1 is provided with two through holes 1-1 radially penetrating through the shaft wall of the shaft sleeve, two connecting bolts I2-3 respectively penetrate through the two through holes 1-1 to be in threaded connection with the upper end and the lower end of the connecting shell 2-2, and the connecting shell 2.
The working principle is as follows: after the mounting is finished, the threaded push rod 2-1 is rotated through a wrench or a hand, the connecting shell 2-2 moves outwards along the threaded push rod 2-1, and the shaft sleeve 1 is driven to move outwards through the connecting bolt I2-3, so that the shaft sleeve 1 is gradually separated from the auger shaft.
The pressure bearing 2-4 can bear axial pressure, plays a role in reducing friction force, and can prevent the thread push rod 2-1 from directly abutting against the auger shaft, and excessive friction force is generated in the rotating process of the thread push rod 2-1 to influence the rotation of the thread push rod 2-1 and the working efficiency.
The bottom plate 2-7 is used for increasing the stress area of the auger shaft and reducing the pressure.
The bottom plate 2-7 and the pressure bearing 2-4 are detachably and fixedly connected through at least two nuts 2-5 and connecting bolts 2-6. The bottom plate 2-7 is a replaceable part, and the bottom plate 2-7 is replaced according to the diameter of the shaft sleeve 1 and the condition of the auger shaft.
As shown in fig. 1, the tool for detaching the shaft sleeve of the asphalt concrete paver further comprises at least one supporting device 3, the supporting device 3 is used for supporting the shaft sleeve 1, and due to the weight of the shaft sleeve 1, the shaft sleeve 1 is prevented from being directly hammered on the ground after being detached, certain pressure is brought to workers who are holding the threaded push rod 2-1, and damage is avoided, and the supporting device 3 comprises a connecting rod 3-5, two supporting rollers 3-1, two roller frames 3-2, two upright posts 3-3 and two supports 3-4; the upper ends of the two supports 3-4 are connected with the upright posts 3-3 through fixing bolts, the included angle between the upright posts 3-3 and the supports 3-4 can be adjusted, so that the angle of supporting rollers 3-1 on the upper ends of the two supports can be adjusted, the upper ends of the upright posts 3-3 are integrally connected with the corresponding roller frames 3-2, the supporting rollers 3-1 are rotatably mounted in each roller frame 3-2, the rotating direction of the supporting rollers 3-1 is the same as the axial direction of the shaft sleeve 1, the two supports 3-4 are placed below the shaft sleeve 1, the angle of the two supporting rollers 3-1 is adjusted, the two supporting rollers 3-1 are symmetrically attached to two sides of the shaft sleeve 1 and used for supporting the shaft sleeve 1, and the two supports 3-4 are connected through connecting rods. Increasing the stability of the support means 3. Because the supporting roller 3-1 can adjust the angle, the bearing sleeve is suitable for shaft sleeves 1 with different diameters.
As shown in fig. 1, each of the brackets 3-4 is a telescopic bracket fixed by a jackscrew. The height of the supporting device 3 can be conveniently adjusted according to specific construction conditions.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
