Referring to fig. 1 to 6, a pair of lifter plates 2 are respectively provided in a pair of fixing grooves 102, and the lifter plates 2 are used to fix electrical devices of construction machinery, such as a generator and a motor.

Wherein, the lifting plate 2 is internally provided with a fixing mechanism. The engineering mechanical electrical equipment can be fixed by the fixing mechanism, so that the engineering mechanical electrical equipment can be firmly placed on the test bench 101, and the safety of the engineering mechanical electrical equipment is ensured.

In addition, a movable groove 201 is provided in the lifting plate 2 for accommodating the guide bar 202 and the fixed block 203. The fixing mechanism comprises a guide rod 202, and the guide rod 202 is fixedly connected in the movable groove 201. The guide rod 202 is used for guiding the sliding of the fixed block 203 so as to adjust the positions of the fixed block 203 and the screw 204, so that the screw 204 can fix different types of engineering machinery electrical equipment.

Specifically, a fixed block 203 is slidably disposed on the guide rod 202, and is used for mounting a screw 204, and the screw 204 is connected to the fixed block 203. The engineering mechanical electrical equipment can be fixed by the screws 204, so that the safety of the engineering mechanical electrical equipment in an electrical experiment is ensured.

During the lifting of the lifting plate 2, the support plate 208 rotates out of the receiving groove 207 due to gravity. When the lifting plate 2 rises to be just coplanar with the test bench 101, the supporting plate 208 is in a vertical state, and the lifting plate 2 can be supported by the supporting plate 208 in the vertical state, so that the screws 204 on the lifting plate 2 can be firmly used for installing engineering mechanical electrical equipment, and the safety of the engineering mechanical electrical equipment is ensured. The sliding fixed blocks 203 are positioned in the movable grooves 201, the distance between the pair of fixed blocks 203 is adjusted, the engineering machinery electrical equipment is fixed through the cooperation of screws 204 and bolts, and then the testing equipment main body 1 is used for carrying out electrical experiments on the engineering machinery electrical equipment.

When it is necessary to perform an electrical experiment on a large-sized electrical device of the construction machine, the rope buckle is pulled from the movable groove 201, and the rope buckle pulls the support plate 208 to rotate through the pull rope 209, so that the support plate 208 is in a non-vertical state, and at this time, the support plate 208 does not support the lifting plate 2. The screw rod 206 is reversely rotated, so that the sliding block 205 descends in the sliding groove 103, and the lifting plate 2 descends in the fixed groove 102. At this time, the support plate 208 can be slowly accommodated in the accommodating groove 207 by the bottom wall of the fixing groove 102. When the lifting plate 2 moves to the bottom of the fixed slot 102, the screw 204 can be completely contained in the fixed slot 102, so that the test bench 101 is not easy to bulge, and the large-size engineering mechanical and electrical equipment can be conveniently placed.
