Detailed Description

Referring to fig. 1, 2 and 3, the roll-over stand for maintaining the automobile engine comprises a base 1, wherein an inner cavity 11 is formed in the base 1, a strip-shaped hole 12 is formed in the inner cavity 11, a limiting rod 13 is slidably arranged in the strip-shaped hole 12, a first cylinder 14 is fixed on the limiting rod 13, a first motor 15 is fixed on a piston rod of the first cylinder 14, a clamping seat 16 is fixed on a rotating shaft of the first motor 15, and a threaded knob 17 is arranged on the clamping seat 16.

Referring to fig. 1, bearings 2 are fixedly embedded in both sides of the inner wall of the inner cavity 11, and a support shaft 21 is in interference fit with an inner ring of the bearing 2, so that the support shaft 21 can rotate stably.

Referring to fig. 1, a second motor 22 is fixed on the base 1, a rotating shaft of the second motor 22 is connected with the supporting shaft 21 through a coupling, and the second motor 22 plays a driving role to ensure the normal rotation of the supporting shaft 21.

Referring to fig. 1, the supporting shaft 21 is provided with a threaded protrusion 23, and the threaded protrusion 23 is provided with two sections in opposite directions, so that the two holders 16 can simultaneously approach or separate from each other.

Referring to fig. 1, the thread of the thread protrusion 23 is provided with a thread bushing 24, the thread bushing 24 is fixedly connected with the limiting rod 13, and the thread bushing 24 can drive the limiting rod 13 to drive.

Referring to fig. 2, a threaded hole is formed in the clamping base 16, the threaded knob 17 is in butt joint with the threaded hole through threads, and the threaded knob 17 can compensate for a clamping gap of the engine and ensure stability during overturning.

Referring to fig. 1, a second cylinder 3 is fixed on a base 1, a supporting plate 31 is fixed on a piston rod of the second cylinder 3, and the supporting plate 31 can play a role of supporting and placing to assist the engine to be stably clamped.

First motor 15 and second motor 22 are three-phase asynchronous machine, and all pass through the wire and the circular telegram of indoor 380V power grafting, and three-phase asynchronous machine power is big, and stability is high, are fixed with first positive reverse switch through the wire on the casing of first motor 15, are fixed with the positive reverse switch of second through the wire on the casing of second motor 22, and the model of first positive reverse switch and the model of the positive reverse switch of second are HY 2-8.

The working principle of the scheme is as follows: when the engine needs to be positioned, the engine is firstly placed on the supporting plate 31 and pushed according to the piston rod of the second cylinder 3, so that the supporting plate 31 can move up and down to adjust the supporting height.
