It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one.

The hydraulic cutting device provided by the embodiment of the application is described in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 1 to 10, an embodiment of the present application discloses a hydraulic cutting apparatus, which includes a walking device 100, a cantilever 210, a positioning device 300, and a cutting device 400. The walking device 100 is a supporting mechanism of the hydraulic cutting equipment, the walking device 100 is provided with a first end face and a second end face, the first end face faces the ground, the cantilever 210, the positioning device 300 and the cutting device 400 are all arranged on the second end face of the walking device 100, the walking device 100 can move, and the cantilever 210, the positioning device 300 and the cutting device 400 are driven to move.

The cantilever 210 has a length, and a first end of the cantilever 210 is rotatably connected to the walking device 100 about a first axis a. Specifically, the first end of the cantilever 210 may be rotatably connected to the walking device 100 by a pin connection, but other rotatable connections may be used therebetween. The cutting device 400 and the positioning device 300 are both arranged at the second end of the cantilever 210, the subsequent positioning device 300 needs to be in direct contact with the equipment to be cut, the cutting device 400 needs to perform cutting operation on the equipment to be cut in a short distance, and the walking device 100 can be far away from the high-temperature smoke environment where the equipment to be cut is located due to the fact that the walking device 100 is far away from the cutting device 400 and the positioning device 300.

As shown in fig. 2 and 5, the positioning device 300 includes a first guide portion 310 and a second guide portion 320, and the device to be cut can extend between the first guide portion 310 and the second guide portion 320, wherein the first guide portion 310 and the second guide portion 320 are spaced apart along a first direction perpendicular to a plane defined by the extending direction of the cantilever 210 and the first axis a. It should be noted that the extending direction of the cantilever 210 is the X direction in fig. 1, the direction of the first axis a is the Y direction in fig. 1, and the first direction is the Z direction in fig. 1.

The traveling device 100 moves the device thereon, or the cantilever 210 rotates around the first axis a, so that the device to be cut can be located between the first guide part 310 and the second guide part 320. In the case that the device to be cut is located between the first guide part 310 and the second guide part 320, the walking device 100 continues to approach the device to be cut, the device to be cut will extend into the space between the first guide part 310 and the second guide part 320 in the direction from the second end of the cantilever 210 to the first end of the cantilever 210, and the first guide part 310 and the second guide part 320 move relative to the device to be cut due to the unchanged position of the device to be cut, that is, the positioning device 300 together with the cantilever 210 will rotate by a certain angle around the first axis a.

In the direction from the second end of the cantilever 210 to the first end of the cantilever 210, as the distance between the first guide part 310 and the second guide part 320 decreases, the space between the first guide part 310 and the second guide part 320 for accommodating the device to be cut becomes smaller and smaller until the outer surface of the device to be cut contacts with both the first guide part 310 and the second guide part 320, which indicates that the device to be cut cannot move relative to the first guide part 310 and the second guide part 320 any more, that is, the device to be cut is clamped between the first guide part 310 and the second guide part 320, and the positioning device 300 is fixed relative to the device to be cut, thereby realizing the positioning process.

Specifically, the first guide portion 310 and the second guide portion 320 may have the same structure or different structures. In this embodiment, the sides of the first guiding portion 310 and the second guiding portion 320 facing each other are both wedge-shaped structures, and the wedge-shaped structures have a guiding function.

In this way, no matter the device to be cut is firstly contacted with the first guide part 310 or firstly contacted with the second guide part 320, when the device to be cut moves along the wedge structure, the wedge structure guides the device to be cut, so that the device to be cut moves relative to the first guide part 310 and the second guide part 320 more smoothly until the device to be cut is contacted with both the first guide part 310 and the second guide part 320. Of course, the side of the first guide portion 310 facing the second guide portion 320 may have a wedge-shaped structure, or the side of the second guide portion 320 facing the first guide portion 310 may have a wedge-shaped structure.

In other embodiments, the sides of the first guide portion 310 and the second guide portion 320 facing each other may have an arc-shaped structure, and may have other structures as long as the distance between the first guide portion 310 and the second guide portion 320 decreases in the direction from the second end of the cantilever 210 to the first end of the cantilever 210.

Due to the arrangement, even if the hydraulic cutting equipment needs to be buffered in a retracting process, the cutting device 400 can be moved to the position before retracting through the process again, the feeding positions are the same, the positioning precision is high, and the cutting efficiency is not influenced; moreover, only need rely on naked eye to make to treat that the cutting equipment roughly lies in between first guide part 310 and the second guide part 320 can, need not to rely on naked eye to come accurate positioning, reduce the degree of difficulty of macroscopic observation, also avoid the problem of macroscopic observation difficulty under high temperature flue gas environment simultaneously.

In this embodiment, the equipment to be cut may be a wellhead, such as a tree.

Alternatively, as shown in fig. 1 and 3, the second end of the cantilever 210 may be provided with a support foot 212. In this way, the supporting foot 212 can support the second end of the cantilever 210, so as to prevent the second end of the cantilever 210 from directly contacting the ground, and ensure that the extending direction of the cantilever 210 is parallel to the ground.

In an alternative embodiment, as shown in fig. 1 and 2, the hydraulic cutting arrangement may include a support bracket 220, a pull rod 230, and a flexible connector 240. One end of the support frame 220 is connected to the first end of the cantilever 210, and the other end of the support frame 220 is connected to the middle position of the cantilever 210 through the pull rod 230, so that the support frame 220 and the pull rod 230 can rotate around the first axis a along with the cantilever 210, that is, the support frame 220, the cantilever 210 and the pull rod 230 form a whole, and the three rotate around the first axis a together.

In this embodiment, the connection point of the drawbar 230 and the cantilever 210 is close to the second end of the cantilever 210, so that the first end of the cantilever 210 is connected to other positions of the cantilever 210 through the support frame 220 and the drawbar 230, and the synchronism of the rotation of the cantilever 210 around the first axis a is improved, thereby preventing the first end of the cantilever 210 and the second end of the cantilever 210 from being unable to rotate synchronously due to the large length of the cantilever 210.

Specifically, one end of the support frame 220 and the first end of the cantilever 210 may be connected by welding, a threaded connection (e.g., a bolt), and the like, and similarly, the tie rod 230 and the cantilever 210, and the tie rod 230 and the other end of the support frame 220 may also be connected by welding, and the like.

Furthermore, as shown in fig. 2, the first ends of the supporting frame 220 and the cantilever 210 are rotatably connected to the walking device 100 about a second axis B, which is parallel to the first direction. In this embodiment, as shown in fig. 6, the cantilever 210 and the supporting frame 220 may be connected by an ear plate, the walking device 100 is provided with a rotating support 250, the cantilever 210 and the supporting frame 220 can rotate around a first axis a relative to the walking device 100 by the rotating support 250, one side of the rotating support 250 opposite to the walking device 100 is also provided with an ear plate, and the two ear plates are connected by a pin, so that the cantilever 210 and the supporting frame rotate around a second axis B. Of course, the cantilever 210 and the supporting frame 220 can rotate around the second axis B relative to the walking device 100 in other manners.

Specifically, a first end of the flexible connector 240 is connected to the other end of the supporting frame 220, and a second end of the flexible connector 240 is used for connecting an external traction device, under the action of which the supporting frame 220 and the cantilever 210 rotate around the second axis B. In this embodiment, the flexible connector 240 is a wire rope, and the external traction device may be a bulldozer, and the wire rope is connected to the bulldozer.

So set up, utilize outside traction equipment to pull or release wire rope, can make the whole of support frame 220, cantilever 210 and pull rod 230 rotate around second axis B, when practical application, just raise or reduce the position of the second end of cantilever 210, and then raise or reduce cutting device 400's position to make cutting device 400 and the position of waiting to cut the equipment correspond, avoid high improper the position that leads to waiting to cut can't correspond cutting device 400.

However, after the position of the second end of the cantilever 210 is changed, the position of the first end of the cantilever 210 is not changed, so the extending direction of the cantilever 210 is changed, and the cutting device 400 is disposed on the cantilever 210, and the cutting direction of the cutting device 400 is easily changed, which is equivalent to that the cutting device 400 is also rotated by a certain angle around the second axis B.

In order to solve the above problem, the hydraulic cutting apparatus further includes a telescopic device 500, the telescopic device 500 is disposed on the second end surface of the walking device 100, and the telescopic device 500 is connected to the first end of the cantilever 210 to drive the first end of the cantilever 210 and the supporting frame 220 to move along the first axis a. Specifically, the telescopic device 500 may be a telescopic cylinder, i.e., a pneumatic cylinder, an oil cylinder, etc., or may be a linear actuator, which can drive the first end of the cantilever 210 and the supporting frame 220 to move along the first axis a.

As shown in fig. 6, the retractable device 500 is disposed between the rotary support 250 and the ear plate, and the cantilever 210 and the support frame 220 rotate around the first axis a while the retractable device 500 is driven to rotate. Of course, in other embodiments, the telescopic device 500 may be directly disposed on the second end face of the walking device 100, that is, the first end of the telescopic device 500 is connected to the walking device 100, the second end of the telescopic device 500 drives the rotating support 250 to move, and the rotating support 250 is disposed between the telescopic device 500 and the ear plate, in this case, the telescopic device 500 does not rotate while the cantilever 210 and the support frame 220 rotate around the second axis B.

With such an arrangement, when the position of the second end of the cantilever 210 is changed, the position of the first end of the cantilever 210 is also changed by the telescopic device 500, so as to keep the extending direction of the cantilever 210 unchanged, that is, the cutting direction of the cutting device 400 is kept unchanged, and the cutting device 400 does not affect the cutting effect.

In this embodiment, the hydraulic cutting apparatus further comprises a first driving member connected to the first end of the cantilever 210, the first driving member can drive the cantilever 210 to move around the first axis a, and the first driving member can rotate with the cantilever 210 around the first axis a. Alternatively, the first driving member may be an electric motor, or may be a hydraulic motor.

Specifically, the first driving member is disposed on the rotating support 250, and in the process that the to-be-cut device extends between the first guide portion 310 and the second guide portion 320, because the cantilever 210, the pull rod 230, and the support frame 220 rotate around the first axis a by a certain angle, the first driving member can rotate around the first axis a along with the cantilever 210 and the support frame 220, and meanwhile, the first driving member can also actively drive the cantilever 210 and the support frame 220 to rotate around the first axis a.

With such arrangement, in addition to the operation of moving the walking device 100, the cantilever 210 and the support frame 220 can be driven to rotate by the first driving member, so as to realize the position movement of the second end of the cantilever 210, and enable the device to be cut to be located between the first guide part 310 and the second guide part 320; moreover, because the weight of the cantilever 210 and the support frame 220 is large, the cantilever 210 is difficult to passively rotate around the first axis a, and the rotation process of the cantilever 210 and the support frame 220 around the first axis a can be smoother by using the first driving member.

In an alternative embodiment, as shown in fig. 1, the hydraulic cutting apparatus further comprises a diverting pulley 110 and a balancing box 120, wherein the diverting pulley 110 and the balancing box 120 are both arranged on the running gear 100, the diverting pulley 110 and the flexible connecting member 240 are positioned on the same side of the running gear 100, the balancing box 120 is positioned at the bottom of the running gear 100, the second end of the flexible connecting member 240 passes around the diverting pulley 110 and is used for connecting an external traction apparatus, and the balancing box 120 is arranged adjacent to the diverting pulley 110, that is, the balancing box 120 is positioned on the side of the cantilever 210 adjacent to the diverting pulley 110 and is also the side of the supporting frame 220 adjacent to the diverting pulley 110.

With such arrangement, the force application direction of the support frame 220 and the pull rod 230 is changed by the flexible connecting piece 240 through the diverting pulley 110, so that the support frame 220, the pull rod 230 and the cantilever 210 can be easily pulled by external traction equipment, and the whole three can easily rotate around the second axis B; furthermore, the gravity of the balance box 120 stabilizes the state of the running gear 100, and prevents the running gear 100 from being tilted by the tensile force of the flexible connecting member 240.

In the technical solution of the present application, the first guide portions 310 and the second guide portions 320 correspond to each other one to one, and are symmetrically disposed with a predetermined axis as a symmetry center. Specifically, the number of the first guide portion 310 and the second guide portion 320 may be one or more. The direction of the preset axis is the same as the extending direction of the cantilever 210, and the preset axis may intersect with both the first axis a and the second axis B.

In an alternative embodiment, the cutting device 400 includes a delivery tube 410, a first nozzle 420, and a drive mechanism. The conveying pipe 410 is disposed on the cantilever 210, a plurality of supports are spaced on the cantilever 210 along the length direction of the cantilever 210, the conveying pipe 410 is lapped on each support, so as to be fixed relative to the cantilever 210, the conveying pipe 410 extends from the first end of the cantilever 210 to the second end of the cantilever 210, the extending direction of the conveying pipe 410 may be the same as the extending direction of the cantilever 210, and of course, the extending direction of the conveying pipe 410 may be different from the extending direction of the cantilever 210. The first nozzle 420 is disposed at an end of the delivery tube 410, and the first nozzle 420 is disposed at a second end of the cantilever 210, and the other end of the delivery tube 410 is used for communicating with a first external liquid supply apparatus.

In this embodiment, the first external liquid supply device may be a fracturing truck for supplying high-pressure liquid or sand-containing liquid, but of course, the first external liquid supply device may also be other types of liquid supply devices. In this way, the first external liquid supply device can provide the conveying pipe 410 and the first nozzle 420 with the sand-containing liquid, and the first nozzle 420 sprays the sand-containing liquid to cut the position to be cut.

The driving mechanism is connected to the conveying pipe 410 such that the driving mechanism drives the conveying pipe 410 to move in a first plane, which is a plane formed by the extending direction of the cantilever 210 and the first direction. The extending direction of the cantilever 210 is the X direction in fig. 3, 4, and 7, and the first direction is the Z direction in fig. 3 and 4, and the Y direction in fig. 7.

Therefore, in the process of injecting the sand-containing liquid by the first nozzle 420, the conveying pipe 410 and the first nozzle 420 are driven to move by the driving mechanism, so that the injection position of the first nozzle 420 is changed, and a complete cutting plane can be cut at the position to be cut.

Alternatively, as shown with reference to fig. 7, the drive mechanism includes a first drive assembly 430, a second drive assembly 440, and a transmission module 450. The transmission module 450 is movably connected to the cantilever 210 along a second direction, where the second direction is a direction in which the cantilever 210 extends, that is, the transmission module 450 can move along the second direction relative to the cantilever 210; the delivery pipe 410 is movably connected to the transmission module 450 in a first direction, that is, the delivery pipe 410 can move relative to the transmission module 450 in the first direction, and the delivery pipe 410 moves along with the transmission module 450 in a second direction while the transmission module 450 moves in the second direction.

The first driving assembly 430 is connected to the transmission module 450 such that the first driving assembly 430 drives the transmission module 450 to move in the second direction, and since the conveying pipe 410 is disposed on the transmission module 450, the first driving assembly 430 can drive the transmission module 450 and the conveying pipe 410 to move in the second direction; the second driving assembly 440 is disposed on the transmission module 450, and the second driving assembly 440 is connected to the conveying pipe 410, so that the second driving assembly 440 drives the conveying pipe 410 to move along the first direction.

Specifically, the first driving assembly 430 may be disposed on the cantilever 210, the second driving assembly 440 may be disposed on the transmission module 450, and since the first driving assembly 430 and the second driving assembly 440 are both driving target parts to move linearly, the first driving assembly 430 and the second driving assembly 440 may be actuators such as linear actuators, air cylinders, and the like.

Thus, the first and

second actuating assemblies

430 and 440 cooperate to effect movement of the delivery tube 410 and the first nozzle 420 in a first plane.

Alternatively, as shown in fig. 7, the first driving assembly 430 includes a first rotary driving member 431, a first lead screw 432, and a first nut 433. The first lead screw 432 is disposed along a second direction, and the second direction is a direction in which the cantilever 210 extends.

The first rotary driving part 431 is connected with the first screw rod 432 to drive the first screw rod 432 to rotate, the first screw rod 432 is matched with the first nut 433, and the first nut 433 is sleeved on the first screw rod 432. Because the first nut 433 is connected to the transmission module 450, and the transmission module 450 is movable relative to the cantilever 210 along the second direction, the first nut 433 can also move along the second direction, that is, the first nut 433 cannot rotate along with the first lead screw 432, the first nut 433 is in limit fit with the first lead screw 432 in the circumferential direction of the first lead screw 432, and the first nut 433 and the first lead screw 432 can be in fit in the spiral transmission direction.

So set up, first rotary driving spare 431 work drive first lead screw 432 rotates, because first lead screw 432 and first nut 433 are at the cooperation of spiral transmission direction, first lead screw 432 is pivoted simultaneously, and first nut 433 moves along the second direction, because first nut 433 is connected with transmission module 450, so first nut 433 drives transmission module 450, conveyer pipe 410, first nozzle 420 and moves along the second direction.

Optionally, as shown in fig. 7 and 8, the second drive assembly 440 includes a second drive member, a drive shaft 442, a diverter 443, and a helical drive assembly 444. The transmission shaft 442 extends along a second direction, which is a direction in which the cantilever 210 extends, that is, the transmission shaft 442 is parallel to the first lead screw 432. Furthermore, second rotary drive element 441 is coupled to drive shaft 442 such that second rotary drive element 441 can drive shaft 442 for rotation.
