DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4As shown, a lifting device for electromechanical installation in a coal mine comprises a base plate 1, four vertical rods 2 are fixedly arranged on the inner wall of the base plate 1, a horizontal plate 3 is installed between the four vertical rods 2, a driving cylinder 4 is installed on the upper end of the horizontal plate 3, a connecting plate 5 is installed on the lower end of the driving cylinder 4, a moving frame 6 is installed on the lower end of the connecting plate 5, eight stabilizing structures 7 are arranged on both sides of the moving frame 6, the stabilizing structure 7 comprises a stabilizing block 8, a guide groove 10 is opened on one side of the vertical rod 2, the stabilizing block 8 enters into the inside of the guide groove 10, and a rolling cylinder 9 is rotatably installed on the front and rear ends of the stabilizing block 8.

[0023] In this embodiment, an extraction structure 11 is disposed inside the movable frame 6 , and the extraction structure 11 includes a placement plate 12 . Sliding grooves 13 are provided on both sides of the movable frame 6 , and both sides of the placement plate 12 are located inside the sliding grooves 13 .

[0024] The placement plate 12 is used to place the transported equipment, so as to facilitate pulling out the equipment for transportation later and increase the working space for the transporters.

[0025] In this embodiment, a knob 14 is provided with internal threads on one side of the moving frame 6, and a receiving hole 15 and a taking-out hole 16 are respectively provided at the front and rear ends of one side of the placement plate 12.

[0026] The knob 14 enters into the storage hole 15 to limit the placement plate 12 .

[0027] In this embodiment, a frame door 20 is rotatably mounted on the front end of the movable frame 6 .

[0028] The frame door 20 is convenient for opening the front end of the movable frame 6 to place the installed equipment.

[0029] In this embodiment, telescopic rods 21 are installed at the four corners of the lower end of the transverse plate 3 , and the lower end of the telescopic rods 21 is connected to the upper end of the connecting plate 5 .

[0030] The telescopic rod 21 can ensure that the connecting plate 5 and the moving frame 6 are stably lowered.

[0031] In this embodiment, connecting rods 18 are installed at the four corners of the lower end of the moving frame 6 , a spring 19 is installed at the lower end of the connecting rod 18 , and a supporting leg 17 is connected to the lower end of the spring 19 .

[0032] The connecting rod 18 is used to install the spring 19, and the spring 19 enables the supporting leg 17 to be stably placed on the uneven bottom of the well.

[0033] In this embodiment, moving wheels are installed at the four corners of the lower end of the base plate 1.

[0034] The moving wheels make it easy for operators to move the bottom plate 1 to the shaft.
