Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a bearing quick-removing device. Background Art

[0002] Most construction machinery contains bearings. After long-term use, the bearings often wear or damage and need to be removed and replaced. However, since most bearings have a small diameter, they cannot be removed with tools such as pliers, and using other tools also has certain difficulties. It is necessary to use a removal tool of appropriate size to remove the bearings. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a bearing quick removal device, which can remove the bearing by screwing the screw rod so that the distance between the two removal rods and the distance between the bearing centers are matched, so that the removal rods are close to the bearing center to remove the bearing.

[0004] The technical solution to achieve the above purpose is a bearing quick removal device, comprising:

[0005] Operating lever;

[0006] Two removal rods fixed to the bottom of the operating rod and arranged opposite to each other; and

[0007] A screw rod is threadedly connected to the side of the taking-out rod, and a portion of the screw rod extends between the two taking-out rods to form a supporting section. By screwing the screw rod, the supporting section pushes against the other taking-out rod.

[0008] Furthermore, a threaded hole is formed on the side of the removal rod, and the screw rod is threadedly connected in the threaded hole.

[0009] Furthermore, a nut is fixedly mounted on the side of the removal rod, the nut is arranged at a position corresponding to the threaded hole, and the screw rod is threadedly connected to the nut.

[0010] Furthermore, the nut is fixed to the side of the removal rod by welding.

[0011] Furthermore, a clamping block is fixed to a side of the taking-out rod away from the operating rod.

[0012] Furthermore, an operating handle is formed on the top of the operating rod.

[0013] Furthermore, the operating rod is made of threaded steel.

[0014] Furthermore, the operating rod is outer-connected with a sleeve, and the inner diameter of the sleeve is matched with the inner diameter of the operating rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The screw rod is screwed to match the distance between the two removal rods with the distance between the centers of the bearings, so that the removal rods are closely attached to the centers of the bearings for removal of the bearings. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] See also Figure 1 A bearing quick removal device comprises: an operating rod 1; two removal rods 2 fixed to the bottom of the operating rod 1 and arranged opposite to each other; and a screw rod 3 threadedly connected to the side of the removal rod 2, wherein a portion of the screw rod 3 extends between the two removal rods 2 to form a supporting section, and by screwing the screw rod 3, the supporting section pushes the other removal rod 2.

[0021] In the present invention, a preferred implementation is: when in use, first insert the two removal rods 2 into the center of the bearing, and screw the screw 3 so that the extension section pushes against the other removal rod 2, so that the interval between the two removal rods 2 increases, until the spacing between the two removal rods 2 matches the diameter of the bearing center, continue to adjust the screw 3, so that the outer walls of the two removal rods 2 and the inner wall of the bearing center are in close contact, and lift the operating rod 1 to remove the bearing.

[0022] Furthermore, the surface of the taking-out rod 2 is formed with anti-slip grooves.

[0023] Further, a threaded hole is formed on the side of the removal rod 2, and the screw rod 3 is threadedly connected in the threaded hole. The screw rod 3 is screwed through the threaded hole, and the size of the threaded hole is adapted to the size of the screw rod 3.

[0024] Furthermore, a nut is fixedly mounted on the side of the removal rod 2, the nut is arranged corresponding to the position of the threaded hole, and the screw rod 3 is threadedly connected to the nut.

[0025] Furthermore, the nut is fixed to the side of the removal rod 2 by welding.

[0026] Furthermore, a clamping block 6 is fixed to the side of the removal rod 2 away from the operating rod 1. Preferably, when in use, firstly, two clamping blocks 6 are passed through the central part of the bearing so that the clamping blocks 6 are placed below the bearing, and the screw rod 3 is adjusted so that the screw rod 3 pushes the two removal rods 2 to fit the inner wall of the center of the bearing, and the operating rod 1 is lifted upward. During the lifting process, the clamping block 6 fits the lower surface of the bearing to facilitate the bearing to be taken out.

[0027] Furthermore, an operating handle 5 is formed at the top of the operating rod 1. The operating handle 5 facilitates an operator to control the operating rod 1, and the operating handle 5 is fixed to the top of the operating rod 1 by welding.

[0028] Further, the operating rod 1 is made of threaded steel. Preferably, the operating rod 1 is made of 16 threaded steel.

[0029] Furthermore, a sleeve 4 is connected to the outer surface of the operating rod 1 , and the inner diameter of the sleeve 4 is matched with the inner diameter of the operating rod 1 .

[0030] The following is an explanation of the use of a bearing quick removal device of the present invention.

[0031] When in use, first pass the two clamping blocks 6 through the central part of the bearing so that the clamping blocks 6 are placed under the bearing, adjust the screw rod 3 so that the screw rod 3 pushes the two removal rods 2 to fit the inner wall of the center of the bearing, and lift the operating rod 1 upward. During the lifting process, the clamping blocks 6 fit the lower surface of the bearing to facilitate the removal of the bearing.

[0032] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings. A person skilled in the art can make various variations of the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation of the present invention, and the scope of protection of the present invention shall be defined by the scope of the attached claims.
