Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile assembly, especially to an auxiliary tool for quickly replacing a large motor coupling. BACKGROUND

[0002] During the operation of mechanical equipment, the motor is usually connected with the equipment by a coupling. The coupling installed on the output end of the motor shaft needs to be replaced regularly (every quarter) due to frequent impact. During replacement, the motor needs to be removed, and enough space needs to be moved to replace the coupling. During the replacement process, the motor is difficult to move and reset, and is prone to rolling, which poses a great safety hazard. In some cases, the space for on-site replacement is narrow. In order to successfully remove the motor, a large number of auxiliary equipment needs to be removed, resulting in a large labor intensity, low efficiency, and great inconvenience and cost waste to the maintenance operation. SUMMARY

[0003] To solve the above problems, the utility model provides an auxiliary tool for quickly replacing a large motor coupling, which can specifically adopt the following technical scheme:

[0004] The auxiliary tool for quickly replacing a large motor coupling comprises a base, a sliding block provided on the base, a pair of sliding blocks, and at least two pairs of sliding blocks. An active frame is provided above the sliding block, the active frame is connected to each sliding block through a lifting mechanism, and the active frame is connected to the base through a translation mechanism. A pair of U-shaped frames for supporting the motor is further provided on the active frame. The U-shaped frames are equidiametered and are arranged along the central axis of the motor. The U-shaped frames, the sliding blocks, and the translation mechanism move in the same direction.

[0005] The base has a rectangular structure composed of a front support rod, a rear support rod, and two side sliding rails. The sliding blocks are slidably provided on the sliding rails.

[0006] The active frame has a rectangular structure. A vertical connecting plate is provided on the front side of the active frame. The vertical connecting plate is connected to the base through the translation mechanism. Each sliding block is correspondingly provided at a corner of the active frame, and the lifting mechanism is provided between the two.

[0007] The translation mechanism is a first lead screw arranged horizontally, and the lifting mechanism is a second lead screw arranged vertically.

[0008] The U-shaped frame and the active frame are detachably connected.

[0009] The auxiliary tool for quickly replacing the large motor shaft coupling provided by the utility model can flexibly and skillfully move the motor out of the original installation position, and facilitates the replacement of the shaft coupling; the detachable double U-shaped frame can stably support the motor, prevent rolling accidents during the movement process, and can also replace U-shaped frames of different sizes according to the motor model, thereby expanding the application range. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1 is a structural schematic view of the utility model. DETAILED DESCRIPTION

[0011] The embodiments of the utility model will be described in detail below with reference to the drawings, and the embodiments are implemented on the premise of the technical scheme of the utility model, and detailed implementation manners and specific working processes are given, but the protection scope of the utility model is not limited to the following embodiments.

[0012] As Figure 1As shown, the utility model discloses a supplementary tool for replacing large motor shaft coupling quickly, including base, and the base is the rectangular structure that is formed by front support rod 11, rear support rod 12 and both sides slide rail 13. The slider 2 is provided on the base, and the slider 2 is provided in pairs, and at least two pairs are provided. In this embodiment, two sliders 2 are respectively provided on each slide rail 13, and the four sliders 2 are distributed in rectangular symmetry. The movable frame 3 of rectangular structure is correspondingly provided above the slider 2, which is connected with the slider 2 through the lifting mechanism respectively, and is connected with the base through the translation mechanism. Specifically, the front side of the movable frame 3 is provided with the vertical connecting plate 4, which is connected with the base through the translation mechanism;The movable frame 3 is correspondingly provided with each slider 2 at the four corners, and four sets of lifting mechanisms are arranged between the two. The translation mechanism adopts the first lead screw 5 arranged horizontally, and the lifting mechanism adopts the second lead screw 6 arranged vertically. A pair of U-shaped frame 7 for supporting the motor is further provided on the movable frame 3, and the U-shaped frame 7 is equidiameter, and is arranged along the motor center axis. In order to improve the scope of application of the device, the U-shaped frame 7 and the movable frame 3 adopt detachable connection structure. In this embodiment, mounting grooves are respectively formed in the center of the front plate and the rear plate of the movable frame 3, and the center of the U-shaped frame 7 is provided with a plugboard matched with the mounting groove, when the U-shaped frame 7 is connected together through the plugboard and the mounting groove, then the two are fixedly connected together through the long bolt. When the four second lead screws 6 are adjusted, the height of the movable frame 3 and the U-shaped frame 7 thereon can be changed;When the first lead screw 5 is adjusted, the slider 2 can move longitudinally along the horizontal slide rail 13, and then the movable frame 3 and the U-shaped frame 7 thereon connected with the slider 2 can move longitudinally synchronously.

[0013] The use method of the utility model is carried out according to the following steps:

[0014] Step one, place the base directly below the motor, determine the direction of the base slide rail 13 according to the actual situation on site;

[0015] Step two, select the appropriate U-shaped frame 7, and install it on the movable frame 3, adjust the second lead screw 6, make the U-shaped frame 7 and the motor bottom surface fit together, further, fix the motor on the U-shaped frame 7 by binding etc., to prevent the motor from rolling out during movement;
