[0033] like Figure 5As shown, the secondary lifting mechanism 4 includes a first threaded sleeve 41 and a second threaded sleeve 40. The top ends of the first threaded sleeve 41 and the second threaded sleeve 40 are both rotatably connected to the parallel plate 3 and the protective frame 31.

The first threaded sleeve 41 and the second threaded sleeve 40 are both provided with a first groove wheel 43 on the upper side walls of the first threaded sleeve 41 and the second threaded sleeve 40. The first driven gear 42 is meshed with the output end of the driving mechanism 5. The interiors of the first threaded sleeve 41 and the second threaded sleeve 40 are both threadedly connected with a threaded column 44.

The advantage of the linkage is that when the protective box 2 is lifted to the top, it is automatically triggered to start unfolding the protective net 9, avoiding forgetting to unfold the protective net 9 during manual construction, and manually unfolding the protective net 9 affects the construction efficiency.

[0034] like Figure 5 As shown, the driving mechanism 5 includes a protective cover 54, a servo motor 51, a power shaft 52 and a driving gear 53.

When the protection box 2 is lifted or lowered, the transmission mechanism 8 rotates through the meshing engagement of the transmission gear 81 with the tooth grooves on the vertical rod 82, so that the rolling gear 84 rotates and drives the tooth plate 85, the connecting seat 86 and the protection box 2 to move forward. Through the forward movement of the protection box 2, the distance between the personnel and the wall is shortened during construction, which is convenient for personnel to construct.

[0036] like Figure 1 and Figure 4 As shown, a slide groove is provided on the top of the base 1, and a linkage mechanism 7 is slidably connected in the slide groove. A protective net 9 is commonly connected between the linkage mechanism 7 and the transmission mechanism 8. The anti-netting protective net 9 is pulled by the linkage mechanism 7 to be unfolded. After unfolding, it can have a certain degree of protection. When the construction workers are working on the side of the equipment, the tools in their hands will not fall off and cause harm to the construction workers or pedestrians on the ground, thereby improving the construction safety and also having the effect of preventing falling.

[0037] like Figure 4 As shown, the linkage mechanism 7 includes a driven block 71, a vertical plate 73 is provided on the top of the driven block 71, the vertical plate 73 is connected to the protective net 9, a contact block is provided at the head end of the driven block 71, a chamfered surface cooperating with the pressing block 46 is opened on the top of the driven block 71, a slider 72 slidably cooperating with the slide groove is provided at the bottom of the driven block 71, a second spring is provided between the slider 72 and the inner wall of the slide groove, two display screens 10 are provided on the top of the base 1, and a touch switch cooperating with the contact block is provided on the side of the two display screens 10 close to the linkage mechanism 7. When the driven block 71 moves in the slide groove, it pushes the touch switch, and the switch is turned on to energize the display screen 10. The warning message displayed on the display screen 10 warns people not to approach the equipment to avoid the equipment on the top of the equipment from falling off and injuring people on the ground.

[0038] Working principle: First, start the driving mechanism 5, and drive the power shaft 52 to rotate through the power output shaft of the servo motor 51, and drive the driving gear 53 to rotate through the power shaft 52, and drive the second driven gear 62 and the first driven gear 42 to rotate through the rotation of the driving gear 53, and drive the second threaded rod 61 to rotate through the rotation of the second driven gear 62, and drive the second grooved wheel 63 to rotate through the rotation of the second threaded rod 61, and drive another set of primary lifting mechanism 6 to rotate with the belt transmission, so as to realize the synchronous rotation of the two second threaded rods 61 driven by the transmission, and the interaction between the threads, the rotation of the second threaded rod 61 drives the transmission mechanism 8 and the protective box 2 to perform synchronous lifting and lowering movements, so as to achieve the purpose of primary lifting;

[0039] Secondly, during this process, the transmission mechanism 8 rotates as the protective box 2 is lifted and lowered through the meshing of the transmission gear 81 with the tooth grooves on the vertical rod 82, so that the rotating bar 83 and the rolling gear 84 are driven to rotate. Through the meshing relationship between the rolling gear 84 and the tooth plate 85, the sliding plate 87 is slidably connected in the bar groove provided on the connecting seat 86, so that the rolling gear 84 rotates and drives the tooth plate 85, the connecting seat 86 and the protective box 2 to move forward.

[0040] The driving gear 53 rotates to drive the first driven gear 42 to rotate, and the first driven gear 42 rotates to drive the first threaded sleeve 41 and the first grooved wheel 43 to rotate. The first threaded sleeve 41 rotates to cooperate with the interaction between the threads and the limiting effect of the limiting rod 45, so that the base 1 is pushed to rise and fall, and the lifting and lowering of the base 1 drives the protective box 2 to achieve secondary lifting;

[0041] Then, as the threaded column 44 is lifted and lowered in the first threaded sleeve 41, the limiting rod 45 is driven to be lifted and lowered synchronously, and the pressing block 46 arranged on the limiting rod 45 moves to the bottom and fits with the driven block 71, and the sliding block 72 arranged at the bottom of the driven block 71 and the sliding groove opened on the top of the base 1 cooperate with each other. When the pressing block 46 descends, it pushes the adjacent driven block 71 to slide in the sliding groove. In this process, only the sliding of the driven block 71 drives the vertical plate 73 connected to the top to move synchronously, and the anti-off-net protection net 9 is pulled to be unfolded;

[0042] Among them, the synchronously moving driven block 71 pushes the touch switch when moving in the slide slot, energizing the display screen 10, and the warning message displayed on the display screen 10 warns personnel not to approach the equipment under construction to avoid the tools in the hands of the construction personnel falling off and injuring people at the bottom of the equipment.
