[0033] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0034] The following describes the spanning network sealing mechanism of the present invention with reference to the accompanying drawings.
[0035] The utility model provides a cross-sealing network mechanism, such as Figure 1 , Figure 2 and Figure 4 As shown, the organizations that cross the network blockade include:
[0036] Telescopic main arm 1;
[0037] A protective net reeling assembly 2 is rotatably connected to the rear end of the telescopic main arm 1 and can be rotated from a folded position to a transversely unfolded position. The protective net reeling assembly 2 is used to reel in the protective net 5;
[0038] The traction assembly 3 is used to pull the protective net 5 to move along the telescopic direction of the telescopic main arm 1 after the protective net winding assembly 2 rotates to the transverse unfolding position.
[0039] In the embodiment of the present invention, the protective net rolling assembly 2 can also be fixed in the transversely unfolded position.
[0040] Specifically: the telescopic main arm 1 is provided with a slide rail 11 extending forward and backward, the protective net winding assembly 2 is rotatably connected to the rear end of the telescopic main arm 1 and can be rotated from a folded position to a laterally unfolded position, the protective net winding assembly 2 is used to wind up one end of the protective net 5, the traction assembly 3 includes a traction movable member 31 slidably arranged on the slide rail 11, a traction rod 32 rotatably connected to the traction movable member 31 and a limiting member 33 for limiting, the rotation direction of the traction rod 32 is the same as that of the protective net winding assembly 2, the traction rod 32 is used to connect the other end of the protective net 5, the limiting member 33 is used to limit the traction rod 32 when the traction rod 32 is rotated to the laterally unfolded position, and the driving member 4 is used to drive the traction movable member 31 to move.
[0041] Since one end of the protective net 5 is rolled up on the protective net winding assembly 2 and the other end is connected to the traction rod 32, when the protective net winding assembly 2 is rotated from the folded position to the laterally unfolded position, the traction rod 32 with the same rotation direction will be pulled by the protective net 5 to rotate synchronously with the protective net winding assembly 2 to the laterally unfolded position. After the traction rod 32 is laterally unfolded, the limit member 33 will limit the traction rod 32 to lock the traction rod 32 in the laterally unfolded posture. In this posture, the traction rod 32 is parallel to the protective net winding assembly 2. At this time, it is only necessary to control the traction movable member 31 to move along the slide rail 11 to pull the protective net 5 out of the protective net winding assembly 2. The pulled out protective net 5 will be spread flat on both lateral sides of the telescopic main arm 1 to protect the area below the telescopic main arm 1. In summary, the spanning sealing net mechanism in the utility model can realize the synchronous retraction and release of the traction rod 32 and the protective net retracting assembly 2, and at the same time, retract the protective net 5 into the protective net retracting assembly 2, and then through the traction of the traction assembly 3, the protective net 5 can be automatically laid quickly and orderly, which not only reduces the labor intensity and simplifies the mechanism structure, but also can realize unmanned operation and reduce construction safety hazards.
[0042] It should be noted that the rotation direction of the traction rod 32 is the same as the rotation direction of the protective net winding assembly 2. Specifically, the rotation center axis of the traction rod 32 is parallel to the rotation center axis of the protective net winding assembly 2. By setting the rotation directions of the two in the same direction, it is ensured that the protective net winding assembly 2 can smoothly pull the traction rod 32 to rotate together when rotating. The telescopic main arm 1 can be composed of multiple telescopic arm sections. The front end of the telescopic main arm 1 refers to the end of the telescopic main arm 1 in the telescopic direction, and the rear end refers to the end of the telescopic main arm 1 close to the base section. The above-mentioned horizontal, vertical, and front-to-back directions are three directions that are perpendicular to each other.
[0043] In the embodiment of the present utility model, the protection net reeling assembly 2 can normally reel the protection net 5 to a state where the traction rod 32 is tightened.
[0044] like Figure 1 As shown, in the embodiment of the utility model, the number of the protective net winding assembly 2 and the traction assembly is generally two groups, and the two groups of protective net winding assemblies 2 and the two groups of traction assemblies are symmetrically arranged on the lateral sides of the telescopic main arm 1.
[0045] like Figure 1 , Figure 2 and Figure 3 As shown, in the embodiment of the utility model, one end of the traction rod 32 is a rotating connection end 321, the rotating connection end 321 is rotatably connected to the traction moving member 31 and the rotation center axis of the rotating connection end 321 extends vertically, and the limiter 33 is arranged on the traction moving member 31 and is located at the rear side of the rotating connection end 321, and the limiter 33 is used to limit the contact with the rotating connection end 321 when the traction rod 32 is rotated to the horizontal unfolding position. When the rotation center axis of the traction rod 32 is arranged vertically, the folding posture of the traction rod 32 is to be attached to the side of the telescopic main arm 1 and the length direction is parallel to the telescopic main arm 1. Of course, the rotation center axis of the rotating connection end 321 can also be arranged to extend in other directions, and the limiter 33 can also be a locking member of other structures such as a latch.
[0046] like Figure 1 As shown, in the embodiment of the utility model, the traction rod 32 is vertically staggered with the protective net winding assembly 2, and the traction rod 32 is located above or below the protective net winding assembly 2, wherein, by moving the traction moving member 31, the rotation center axis of the rotating connection end 321 can be vertically aligned with the rotation center axis of the protective net winding assembly 2. By moving the rotation center axis of the rotating connection end 321 to a position vertically aligned with the rotation center axis of the protective net winding assembly 2, it is more convenient to synchronize the traction rod 32 and the protective net winding assembly 2 to unfold and retract.
[0047] like Figure 1 , Figure 2 and Figure 4 As shown, in an embodiment of the utility model, the protective net winding assembly 2 includes a hoisting box 21 and a hoisting drum 22. The hoisting box 21 is rotatably connected to the outer peripheral wall of the telescopic main arm 1 and the rotation center axis of the hoisting box 21 extends vertically. The hoisting box 21 can be rotated from a folded position to a laterally unfolded position. The hoisting drum 22 is rotatably arranged in the hoisting box 21 and is used to wind up one end of the protective net 5.
[0048] In the embodiment of the present invention, the hoisting drum 22 is driven by an independent motor.
[0049] like Figure 1 and Figure 2 As shown, in an embodiment of the utility model, a limit stopper 23 is further provided at one end of the hoisting box 21 away from the telescopic main arm 1. The limit stopper 23 is located at the rear side of the traction rod 32 and is used to limit and abut the traction rod 32 when the traction rod 32 rotates to a position parallel to the hoisting drum 22.
[0050] like Figure 1 As shown, in the embodiment of the utility model, an unfolding drive cylinder 24 is further provided between the hoisting box 21 and the telescopic main arm 1, and the unfolding drive cylinder 24 is used to drive the hoisting box 21 to rotate from the folded position to the lateral unfolded position. Specifically, one end of the unfolding drive cylinder 24 is connected to a position slightly closer to the middle of the hoisting box 21, and the other end is connected to the side wall of the telescopic main arm 1, so as to form a more stable triangular structure.
[0051] The following is an explanation of the above structure in conjunction with the working process of the cross-network blocking mechanism:
[0052] like Figure 1 and Figure 2 As shown, when the crossing sealing mechanism needs to be unfolded, it is first necessary to ensure that the rotation center axis of the traction rod 32 and the protective net winding assembly 2 are aligned. When the unfolding drive cylinder 24 drives the hoisting box 21 and the hoisting drum 22 to rotate to the horizontal unfolding position, the traction rod 32 is pulled by the protective net 5 and rotates with the protective net winding assembly 2 until the traction rod 32 contacts the limit member 33 and the limit block 23. The purpose of setting the limit block 23 is to avoid the traction rod 32 from being over-pulled and to ensure the parallelism of the traction rod 32 and the hoisting drum 22. When the protective net winding assembly 2 and the traction rod 32 are both unfolded horizontally, the traction rod 32 and the hoisting drum 22 will be in a parallel state. At this time, it is only necessary to drive the traction moving member 31 to move on the slide rail 11, so that the protective net 5 can be smoothly pulled out of the protective net winding assembly 2 and laid flat on the lateral sides of the telescopic main arm 1.
[0053] When the crossing sealing net mechanism needs to be retracted, the traction moving member 31 is first controlled to move so that the rotation center axis of the traction rod 32 is vertically aligned with the rotation center axis of the protective net winding assembly 2. At this time, the protective net winding assembly 2 will roll up the excess protective net 5 on the hoisting drum 22, and then drive the hoisting box 21 to rotate horizontally toward the folded position through the unfolding driving cylinder 24. During the retraction process of the hoisting box 21, the limit block 23 is set, and the limit block 23 will push the traction rod 32 to rotate together, thereby realizing the synchronous retraction of the protective net winding assembly 2 and the traction rod 32. Before unfolding and retracting, the present mechanism first moves the rotation center axis of the traction rod 32 to a position vertically aligned with the rotation center axis of the protective net winding assembly 2, and then ensures the parallelism of the traction rod 32 and the hoisting drum 22 through the limit block 23, so that the protective net 5 can be pulled out of the protective net winding assembly 2 more smoothly or rolled into the protective net winding assembly 2 more smoothly.
[0054] Of course, in an embodiment of the utility model, the rotation center axis of the rotating connection end 321 can also be set to be parallel and staggered with the rotation center axis of the protective net winding assembly 2 when the mechanism is unfolded or retracted. At this time, the limit position of the limit block 23 on the winch box 21 needs to be adjusted accordingly.
[0055] In the embodiment of the utility model, a sensing element is further provided on the telescopic main arm 1 and / or the traction movable member 31, and the sensing element is used to send a sensing signal when the rotation center axis of the rotating connection end 321 moves to a position aligned with the rotation center axis of the protective net winding assembly 2. When the sensing element sends a sensing signal, the controller will control the driving member 4 to stop running, and the traction movable member 31 can stop accurately at a position where the rotation center axis of the traction rod 32 is vertically aligned with the rotation center axis of the protective net winding assembly 2.
[0056] like Figure 4 and Figure 5 As shown, in the embodiment of the utility model, the telescopic main arm 1 can be a multi-section telescopic arm, and the slide rail 11 is a bamboo-section type and can be synchronously extended and retracted with the telescopic main arm 1. By setting the telescopic main arm 1 to be retractable, the span across the sealing net mechanism can be extended, so that the protective net 5 can cover a wider range.
[0057] like Figure 2 and Figure 3 As shown, in an embodiment of the utility model, the driving member 4 can be a traction rope arranged on the telescopic main arm 1, and the traction rope can be linked with the synchronous telescopic mechanism in the telescopic main arm 1, and can also be driven by an independent driving unit.
[0058] like Figure 4 and Figure 5As shown, in an embodiment of the present utility model, the crossing sealing mechanism further includes a lifting frame 61 and a turntable 62. The lifting frame 61 can lift the telescopic main arm 1 to a preset height, and the turntable 62 can adjust the direction of the telescopic direction.
[0059] In an embodiment of the utility model, the spanning sealing mechanism further includes a distal support leg 63, and the distal support leg 63 is arranged at the front end of the telescopic main arm 1 to provide distal support for the door frame.
[0060] In order to achieve the above-mentioned purpose, the utility model also provides a cross-net sealing operation equipment, wherein the cross-net sealing operation equipment includes the cross-net sealing mechanism described above. Since the cross-net sealing operation equipment adopts all the technical solutions of the above-mentioned embodiments, it at least has the beneficial effects brought by the above-mentioned embodiments, which will not be repeated here.
[0061] like Figure 5 As shown, in an embodiment of the present utility model, the crossing net sealing operation equipment may be a crossing net sealing operation vehicle 7, and the crossing net sealing operation vehicle 7 may realize the rapid transfer of the crossing net sealing mechanism.
