fixed plate 220, fixed plate 220 fixes the both ends in roof 110 bottom, sliding tray 221 has been seted up to the lateral wall of driven lever 210, it is provided with sliding block 222 to slide in sliding tray 221, sliding block 222 is connected with the other end of connecting rope 211, the lateral wall of sliding block 222 is provided with supporting bench 223, through the elevating gear 200 who sets up, sliding plate 114 outwards slides and connects rope 211 through the pulling of driven lever 210, driven lever 210 slides and supports sliding plate 114 in fixed block 115, it moves through sliding block 222 pulling supporting bench 223 to connect rope 211, supporting bench 223 atress rises can drive the material and rise, so that transport the material when improving stability between sliding plate 114 and the roof 110.

When the supporting device 100 and the lifting device 200 of this embodiment are used specifically, the movable end of the electric push rod 113 pushes the sliding plate 114 to slide towards the two ends of the top plate 110, the sliding plate 114 slides to drive the driven rod 210 to move, the driven rod 210 moves in the fixed block 115, due to the limitation of the fixed block 115, the driven rod 210 supports the sliding plate 114 through the fixed block 115 to share the force applied to the sliding plate 114, meanwhile, the driven rod 210 moves to pull the sliding block 222 to rise through the connecting rope 211, the sliding block 222 drives the supporting table 223, and the supporting table 223 rises to drive the material to rise.

In addition, in order to reduce friction between the connection rope 211 and the sliding groove 221, the side wall of the top plate 110 is provided with the connection plate 120, one end of the connection plate 120 is connected with the guide pipe 121, the guide pipe 121 is in an "L" shaped structure, and the connection rope 211 penetrates through the guide pipe 121, and considering that the connection rope 211 becomes inclined in a stressed state, for this reason, the "L" shaped guide pipe 121 can change the direction of the connection rope 211, so that one end of the connection rope 211 longitudinally pulls the sliding block 222, and the connection rope 211 is prevented from contacting the sliding groove 221.

Further, in order to realize the movement of the device, the universal wheel 130 is arranged at the bottom of the supporting rod 111, one end of the sliding plate 114 longitudinally penetrates through the straight rod 131, the bottom of the straight rod 131 is in a conical structure, the conical shape can improve the ground holding force on the straight rod 131, and in consideration of the fact that the device needs auxiliary operation of bottom workers during movement, for this reason, after the sliding plate 114 slides, the straight rod 131 is stepped down, so that the bottom end of the straight rod 131 is in contact with the ground, at this time, the movable end of the electric push rod 113 contracts to generate a pulling force, and one end of the sliding plate 114 cannot contract due to the limitation of the straight rod 131, at this time, the electric push rod 113 drives the universal wheel 130 to move through the top plate 110 and the supporting rod 111, so that the help of the workers below is needed, and when the device is worth explaining, the ground during construction is in a blank state, so that the ground cannot be smoother.

Further, in order to prevent the straight rod 131 from contacting the ground to generate more abrasion, the top end of the straight rod 131 is provided with the connecting disc 132, the return spring 133 is arranged between the connecting disc 132 and the sliding plate 114, and considering that the return spring 133 moves down by gravity to contact the ground, therefore, when the straight rod 131 is not stressed, the return spring 133 jacks up the connecting disc 132 through self elasticity, the connecting disc 132 drives the straight rod 131 to move upwards, the straight rod 131 moves upwards to be separated from the ground, and further, the straight rod 131 is prevented from contacting the ground to generate more abrasion.

Specifically, in order to improve the smoothness of the sliding block 222 during sliding, the side wall of the fixing plate 220 is provided with a rotating groove, the ball 224 is rotatably disposed in the rotating groove, the side wall of the ball 224 is attached to the outer wall of the sliding groove 221, and considering that the contact area between the sliding block 222 and the sliding groove 221 is large, therefore, the contact area between the sliding block 222 and the sliding groove 221 is reduced by the disposed ball 224, and meanwhile, the sliding friction between the sliding groove 221 and the sliding block 222 is converted into rolling friction by the ball 224, so that the rolling friction force is small, and further, the smoothness of the sliding block 222 during sliding is improved.

In addition, in order to improve the transportation type of the support platform 223, a plurality of slots 230 are formed in the surface of the support platform 223, insertion rods 231 are inserted into the slots 230, and stop rods 232 are arranged between the insertion rods 231, so that the operation space of the device is enlarged after the sliding plate 114 extends, therefore, objects on the surface of the support platform 223 can be stopped through the arranged stop rods 232, the transportation stability is improved, and meanwhile, the arranged stop rods 232 can lift constructors.

Further, in order to prevent the sliding block 222 from rapidly descending due to the breakage of the connecting rope 211, one side of the fixing plate 220 is provided with a plurality of slideways communicated with the sliding groove 221, the connecting columns 240 are all arranged in the slideways in a sliding manner, one end of each connecting column 240 in the sliding groove 221 is obliquely arranged, the other ends of the connecting columns 240 are connected through a long plate 241, a compression spring 242 is arranged between the long plate 241 and the side wall of the fixing plate 220, and the sliding block 222 is contacted with the connecting columns 240 when ascending in consideration of the damage to articles caused by the rapid descending of the sliding block 222, and the connecting column 240 is pushed by the inclined surface of the connecting column 240, at this time, the sliding block 222 can pass through the connecting column 240, when the sliding block 222 falls, the bottom of the sliding block 222 contacts the top of the connecting column 240, the connecting column 240 blocks the sliding block 222, so that the sliding block 222 cannot fall down, and the sliding block 222 is prevented from falling down rapidly due to the fracture of the connecting rope 211.
