from entering the bottom end of the transverse plate 19, the first guard rail 23 and the second guard rail 25 are slidably inserted into the inner part of the fixing sleeve 28 through the first inserting rod 27, the fixing sleeve 28 is symmetrically and fixedly welded at the top end of the guard chassis 32, the transverse plate 19 can be fixedly welded at the top end of the first inserting rod 27, so that the transverse plate 19 can be ensured to move upwards or downwards along a straight line, the top end of the limit inserting rod 30 is fixedly welded at the top end of the limit inserting rod 29, the limit inserting rod 30 is slidably inserted into the inner part of the bottom plate 31, the side end of the limit inserting rod 29 can be fixedly welded at the side end of the transverse plate 19, when the, can avoid removing roof 29 and drop from bottom plate 31, rotate through shrouding 34 and connect inside the side of bottom plate 31, and magnet 35 fixed connection is at the side of shrouding 34, the inside fixedly connected with iron sheet of side of bottom plate 31, can be with shrouding 34 internal rotation angle, until driving magnet 35 and adsorbing on the iron sheet, be convenient for shrouding 34 to open or close, rotate through rotating diaphragm 33 and connect on shrouding 34, when removing roof 29 and move down to the parallel and level with bottom plate 31, can be with rotating diaphragm 33 internal rotation angle, thereby can be with rotating diaphragm 33 overlap joint on removing roof 29, and it is perpendicular with shrouding 34 when rotating diaphragm 33 outwards to extreme position, make can cooperate and remove roof 29 when rising to extreme position, close the inside of diaphragm 19, be convenient for later maintenance and maintenance.

When the lifting device 1 is the screw 36, the connecting plate 37, the second plunger 38, the sleeve 39, the threaded sleeve 40 and the motor 41, the connecting plate 37 can be fixedly welded at the bottom end of the transverse plate 19, and is fixedly connected at the top center of the motor 41 through the threaded sleeve 40, and the screw rod 36 is inserted in the threaded sleeve 40 in a threaded manner, the motor 41 can be energized to cause the threaded sleeve 40 to rotate, and when the threaded sleeve 40 is rotating, can drive the screw rod 36 to move upwards, is fixedly connected with the top end of the screw rod 36 through the connecting plate 37, and the second insert rods 38 are symmetrically and fixedly connected to the bottom end of the connecting plate 37, so that the stable upward movement of the connecting plate 37 can be ensured, the second inserting rod 38 is slidably inserted into the sleeve 39, so that the second inserting rod 38 can be allowed to slide up and down in the sleeve 39, and the phenomenon that the connecting plate 37 is inclined when ascending or descending is avoided.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
