The stand is installed subaerial, is provided with backup pad 2 on the stand, and backup pad 2 can provide the workman to overhaul the operation as operation platform. Be equipped with guardrail 3 around backup pad 2, guardrail 3 plays the guard action to backup pad 2 all around, prevents that personnel from falling from backup pad 2. A goods passage 4 is provided on the support plate 2, which goods passage 4 extends through the support plate 2, so that equipment and material located below can be transported from the goods passage 4 onto the support plate 2. Still set up hoisting accessory 5 in the backup pad 2, can put the below from goods passageway 4 with hoisting accessory 5's lifting rope and lift by crane equipment and goods, convenient transport.

Be equipped with protection cover plate 6 at goods passageway 4, utilize protection cover plate 6 to shelter from goods passageway 4, prevent that the staff from falling down from goods passageway 4, improve the security performance, avoid the emergence of the accident of falling. When equipment or goods need to be carried, the protective cover plate 6 automatically opens the opening matched with the outline of the goods or the equipment, the opening just allows the equipment or the goods to pass through, and the risk that people fall from the opening is prevented. Specifically, protective cover 6 include a plurality of with 2 swing joint's of backup pad horizontal pole 7 with be used for driving the gliding electric telescopic handle 8 of horizontal pole 7, when the guard plate was closed goods passageway 4, electric telescopic handle 8 promoted the horizontal pole 7 of both sides and removed to the centre to close goods passageway 4. For convenience of explanation, the present invention defines the direction in which the L-shaped bar 13 moves toward the edge of the cargo passage 4 as the right side. When goods need to be carried, a worker tool pushes the L-shaped rod to move rightwards, no support is arranged at the bottom of the L-shaped rod 13 at the moment, the L-shaped rod moves to the lower right side at the moment, the power supply 14 supplies power to the electric telescopic rod 8 through the second double-pole sliding switch 10 and the first double-pole sliding switch 9 at the moment, the electric telescopic rod 8 works to enable the length of the L-shaped rod to be shortened at the moment, the protective cover plate 6 opens one opening, a worker places a hook supply opening of the lifting device 5 below the hook supply opening, the L-shaped rod 13 resets under the action of the first spring piece after the worker opens the tool, the L-shaped rod 13 moves to the lower left side, the power supply 14 supplies power to the electric telescopic rod 8 through the second double-pole sliding switch 10 and the first double-pole sliding switch 9 at the moment, the polarity of the power supply 14 switched on by the electric telescopic rod 8 is opposite, the electric telescopic rod 8 works to enable the length of the electric telescopic rod to extend, and the opening is reduced. Until the electric telescopic rod 8 moves to be in contact with the lifting rope of the lifting device 5, the L-shaped rod 13 is extruded and pushed to move to the right side, when the L-shaped rod moves to the middle-lower position, the first double-blade sliding switch 9 is switched off, the electric telescopic rod 8 stops moving, and the opening profile of the goods passage 4 is maintained. Hoisting equipment or goods upwards through hoisting accessory 5, after the top of goods contacts and extrudes the bottom of L shape pole 13, upwards promote the bottom of L shape pole 13 for L shape pole 13 displacement to the position directly over, electric telescopic handle 8 shortens and makes the opening of goods passageway 4 expand this moment, equipment and goods pass through goods passageway 4 upward movement, also can lead to the side of L shape pole 13 to be extruded if the diameter undersize of goods passageway 4 in the transportation, make L shape pole 13 move to lower right position or upper right position, the telescopic link can shorten and make the opening of goods passageway 4 expand this moment, if the opening size of goods passageway 4 can pass through equipment or goods just, L shape pole 13 is located the position directly over or under this moment, electric telescopic handle 8's length does not change, the opening size of goods passageway 4 does not change. L shape pole 13 moves down in the effect of second elastic component 12 after cargo handling, moves left under the effect of first elastic rod for L shape pole 13 is located the position of lower left, and electric telescopic handle 8 extension makes horizontal pole 7 remove and closes goods passageway 4 this moment, and when horizontal pole 7 moved to the position of closing goods passageway 4, L shape pole 13 received the extrusion force, makes L shape pole 13 be located the position directly below, and electric telescopic handle 8 stopped flexible this moment, and goods passageway 4 is closed.

The automatic lifting device can automatically adjust the size of the cargo channel 4 according to the outline size of the lifted equipment or cargo, solves the problem of falling risk of personnel due to the fact that the opening is too large in the lifting process, can automatically close the cargo channel 4 after the equipment or cargo is conveyed, and prevents the problem of falling risk caused by the fact that the personnel forget to close the cargo channel 4.
