[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0015] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, the electric motor transport trolley proposed in this embodiment of the present invention includes a top plate 1, a bottom plate 2, a screw jack 3, a handwheel 4, traveling wheels 5, and a locking device 6; The base plate 2 has four corners on its lower surface with wheels 5 installed; and a screw jack 3 is installed in the middle of the upper surface of the base plate 2. The screw jack 3 includes a base 301, a screw 302 extending upward from the base 301, and an input shaft 303 provided on one side of the base 301; one end of the input shaft 303 is connected to a handwheel 4; the other end of the input shaft 303 is connected to a locking device 6. A connecting seat 101 is installed in the middle of the lower surface of the top plate 1; the top end of the lead screw 302 is connected to the connecting seat 101 through a bearing.

[0016] When the beam reducer motor malfunctions and requires repair, the motor transport trolley can be moved to a position below the reducer motor. Turning handwheel 4 causes the input shaft 303 to rotate. The screw jack 3 contains a worm gear mechanism, which drives the screw 302 to rotate and rise / fall. First, the screw 302 moves the top plate 1 upwards towards the reducer motor, catching it. Then, turning handwheel 4 in the opposite direction causes the top plate 1 to descend a short distance with the reducer motor. The locking device 6 then locks the input shaft 303 of the screw jack 3, preventing the reducer motor from falling further and improving safety during motor transport. The motor transport trolley then carries the reducer motor to a more spacious area within the workshop.

[0017] More preferably, the upper surface of the top plate 1 is provided with a rubber pad 102; the rubber pad 102 can increase friction and prevent the motor under load from slipping.

[0018] Specifically, the locking device 6 includes a support block 601 and a locking rod 602. The support block 601 is fixed on the base plate 2, and the upper part of the support block 602 is provided with a shaft hole for the other end of the input shaft 303 to pass through. An opening groove 603 is provided above the shaft hole of the support block 602, and two shoulders 604 are formed on both sides of the opening groove 603. The locking rod 602 is a bent rod, and its transverse section passes through the two shoulders 604 of the support block 601 and is threadedly connected to the two shoulders 604. The shaft hole at the upper part of the support block 602 is adapted to the input shaft 303 of the screw jack 3. When it is necessary to lock the input shaft 303 of the screw jack 3, the locking rod 602 can be rotated by an angle.

[0019] The screw jack 3 uses commercially available products and can be equipped with a self-locking function. With the addition of a locking device 6, it can achieve a double locking function, which improves safety.

[0020] Furthermore, the traveling wheels 5 installed on the lower surface of the base plate 2 include a pair of directional wheels 501 and a pair of omnidirectional wheels 502; a pair of directional wheels 501 are installed on one side of the base plate 2 in the front-rear direction of the motor transport trolley, and a pair of omnidirectional wheels 502 are installed on the other side; so that the motor transport trolley can change the direction of movement.

[0021] Furthermore, the caster wheel 502 is equipped with a brake; after the motor transport trolley stops in place, the caster wheel 502 is braked to prevent the motor transport trolley from continuing to move.

[0022] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
