[0008] In an embodiment of the utility model, the lifting mechanism includes a lifting frame rotatably mounted on a turntable and a second driving member for driving the lifting frame to lift. The lifting frame can be pitched and rotated to lift the telescopic main arm.

[0009] In an embodiment of the utility model, a first support rod and a second support rod are respectively provided at the front end and the rear end of the telescopic main arm, and both ends of the protective net are respectively connected to the first support rod and the second support rod.

[0031] 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.

[0032] The mobile crossing and sealing net operation equipment of the present invention will be described below with reference to the accompanying drawings.

[0033] The utility model provides a mobile cross-net sealing operation equipment, such as Figure 1 , Figure 2 and Figure 3 As shown, the mobile crossing network blocking operation equipment includes:

[0034] Chassis 1, movable setting;

[0035] A lifting mechanism 2 is arranged on the chassis 1 and is capable of variable lifting;

[0036] The crossing mechanism 3 comprises a telescopic main arm 31 rotatably arranged on the lifting mechanism 2 and a first driving member 32 for driving the telescopic main arm 31 to change its amplitude;

[0037] A first leg mechanism 4 is foldably disposed at the front end of the telescopic main arm 31 and is used for supporting the ground;

[0038] A protective net 5, used for laying on the telescopic main arm 31 along the telescopic direction of the telescopic main arm 31; and

[0039] The counterweight mechanism 6 is used to counterweight the side of the chassis 1 that is away from the telescopic direction.

[0040] When in use, the operating equipment is first moved to a designated position, and then the lifting mechanism 2 is driven to lift the telescopic main arm 31 to a sufficient height. After the telescopic main arm 31 is at a sufficient height, the telescopic main arm 31 is driven to rotate to a horizontal extension state by the first driving member 32, and then the telescopic main arm 31 is controlled to extend horizontally, so that the telescopic main arm 31 can smoothly cross highways, railways and other lines. During the telescopic main arm 31 extension process, or after the telescopic main arm 31 is extended to the right position, the protective net 5 only needs to be laid on the telescopic main arm 31 to protect the highway and railway below the telescopic main arm 31. During the extension process of the telescopic main arm 31, the counterweight mechanism 6 will counterweight the other side of the chassis 1 to ensure the force balance on both sides of the chassis 1, and avoid the accident of the chassis 1 overturning due to the large span of the telescopic main arm 31. The first leg mechanism 4 can support the front end of the telescopic main arm 31 after the telescopic main arm 31 is extended to the right position, thereby ensuring the stability of the operating equipment in the crossing posture. In summary, the mobile crossing and sealing operation equipment in the utility model integrates the crossing mechanism 3 on the movably arranged chassis 1, which can realize the rapid transfer operation of the equipment, and the operation process can increase the stability of the chassis 1 through the counterweight mechanism 6, which greatly reduces the operation risk. At the same time, the construction and dismantling process of the crossing frame is completed automatically by machinery, and the whole process does not require manual erection of the gantry structure, which effectively reduces the labor intensity and improves the operation efficiency.

[0041] like Figure 1As shown, in an embodiment of the utility model, one implementation of the counterweight mechanism 6 can be: the counterweight mechanism 6 includes a ground anchor line 61, one end of the ground anchor line 61 is connected to at least one of the chassis 1, the lifting frame 21, and the telescopic main arm 31, and the other end is used to connect to the ground on the side of the chassis 1 that is not facing the telescopic direction. The entire operating equipment is fixedly connected to the ground by the ground anchor line 61, which can ensure the force balance of the chassis 1 and avoid tipping during operation. It should be noted that before the telescopic main arm is extended, it is necessary to ensure that the ground anchor line is connected to the ground, and when installing the ground anchor line, it is necessary to ensure that its bearing capacity can reach the moment balance condition after the telescopic main arm is extended.

[0042] like Figure 2 As shown, in an embodiment of the utility model, another implementation of the counterweight mechanism 6 can be: the counterweight mechanism 6 includes a counterweight block 62, which is arranged on the chassis 1 and located on the side of the lifting mechanism 2 that is not facing the telescopic direction. The counterweight block 62 is used to perform ballast on the other side, so that the chassis 1 can also be balanced. The counterweight block 62 needs to be adjusted to the correct position before the telescopic main arm is extended, so that the counterweight block meets the torque balance condition after the telescopic main arm is extended.

[0043] like Figure 2 and Figure 3 As shown, in the embodiment of the utility model, a turntable 11 is provided on the chassis 1, one end of the lifting mechanism 2 is rotatably mounted on the turntable 11, and the other end is used for the telescopic main arm 31 to be rotatably mounted, and the counterweight 62 is arranged on the turntable 11 and can be rotated to the side of the lifting mechanism 2 that is not facing the telescopic direction. Specifically, the counterweight 62 and the lifting mechanism 2 can rotate independently, and when the main arm is extended, the counterweight 62 is rotated to the side that is not facing the telescopic main arm 31, which can balance the moment of the chassis 1 and prevent the chassis 1 from overturning. When the distal leg 41 is supported by the ground, the counterweight 62 can be retracted to reduce the floor space.

[0044] In the embodiment of the present utility model, the counterweight block 62 and the lifting mechanism 2 are configured to be able to rotate independently, which can reduce the difficulty of folding.

[0045] like Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the lifting mechanism 2 includes a lifting frame 21 rotatably mounted on the turntable 11 and a second driving member 22 for driving the lifting frame 21 to lift. The lifting frame 21 can be pitched and rotated to lift the telescopic main arm 31. Specifically, one end of the lifting frame 21 is rotatably mounted on the turntable 11, and the other end is connected to the telescopic main arm 31. The lifting frame 21 is driven to rotate up and down around the lower end by the second driving member 22, so that the telescopic main arm 31 can be lifted to a sufficient height. The second driving member 22 can be a gantry oil cylinder, and the gantry oil cylinder preferably forms a stable triangular structure with the lifting frame 21 and the turntable 11.

[0046] like Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the front end and the rear end of the telescopic main arm 31 are respectively provided with a first support rod 71 and a second support rod 72, and the two ends of the protective net 5 are respectively connected to the first support rod 71 and the second support rod 72. The telescopic main arm 31 includes a basic arm section and a multi-section telescopic arm section sleeved in the basic arm section. The first support rod 71 is installed on the basic arm section, and the second support rod 72 is installed on the terminal arm section of the telescopic arm section. When the telescopic main arm 31 is extended, the second support rod 72 will be extended together, thereby pulling the protective net 5 to be spread on the telescopic main arm 31.

[0047] In the embodiment of the utility model, the first support rod 71 and the second support rod 72 are rotatably mounted on the telescopic main arm 31 and driven by the driving member, and the first support rod 71 and the second support rod 72 can be rotated from the folded position to the vertical support position. By rotating the first support rod 71 and the second support rod 72, folding is facilitated. Of course, the first support rod 71 and the second support rod 72 can also be folded and retracted by telescoping.

[0048] like Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the first leg mechanism 4 includes a distal leg 41 rotatably arranged at the front end of the telescopic main arm 31 and a leg cylinder for driving the distal leg 41 to rotate, and the distal leg 41 can rotate from a folded position to a vertical support position to support the ground. The folded position of the distal leg 41 refers to the distal support folded along the telescopic direction of the telescopic main arm 31 and attached to the surface of the telescopic main arm 31, and the distal leg 41 is driven by the leg cylinder to rotate to the vertical support position, so as to support the front end of the telescopic main arm 31, thereby forming a stable frame mechanism for the entire gantry.

[0049] like Figure 1 and Figure 3 As shown, in the embodiment of the utility model, the chassis 1 is provided with a vertically extendable stabilizing leg 12, which is used to extend vertically to support the ground when the chassis 1 is in operation. The chassis 1 can be stably supported by the stabilizing leg 12. It should be noted that since the crossing and sealing net operation equipment in this embodiment uses a counterweight block 62 or a ground anchor line 61, there is no need to set a movable leg that can be deployed horizontally to support the chassis 1, thereby achieving the purpose of simplifying the structure of the chassis 1.

[0050] like Figure 1 , Figure 3 and Figure 3 As shown, in the embodiment of the present utility model, the chassis 1 may be a chassis 1 for an engineering vehicle, such as a tracked chassis 1 or the like.

[0051] In summary, the equipment installs the protective net 5 on the telescopic main arm 31, and by setting the chassis 1 to be movable, the equipment can easily reach the work site, reducing the difficulty of transportation. At the same time, the net sealing process is operated by a mechanical structure, and the entire process does not require manual erection of the gantry structure, which reduces the dependence on manual labor and improves work efficiency. Furthermore, the equipment can be reused, reducing the cost of a single net sealing operation.
