[0024] like Figure 1 , 4 As shown: the hydraulic pump and oil reservoir of the hydraulic telescopic rod 105 can be directly placed on the gantry 104, so that it will not be restricted during operation. The push rod end of the hydraulic telescopic rod 105 is fixedly connected with the first shearing knife 106, so that the hydraulic telescopic rod 105 can easily cut the steel pipe when driving the first shearing knife 106 to move downward. The first shearing knife 106 can be welded to the end of the push rod, so that the first shearing knife 106 can work more stably on the hydraulic telescopic rod 105.

[0026] like Figure 1 , 2 As shown: a conveying mechanism is provided on one side of the two baffles 102, and the conveying mechanism is provided to convey the steel pipe to between the first shearing knife 106 and the second shearing knife 107 so as to shear the steel pipe.

The infrared receiver 307 is also fixed to the upper part of the gantry 104 by bolts. The infrared controller 306 and the infrared receiver 307 are both fixed by bolts, so that they are easy to disassemble and assemble during maintenance or replacement. A storage component is provided on the side of the bottom plate 101 away from the transmission mechanism.

[0027] like Figure 1 , 4As shown: the conveying mechanism includes a plurality of conveying rollers 103 arranged on two baffles 102.

The transmission shaft on each conveying roller 103 is connected to the two baffles 102 through a bearing, so that the rotation of the conveying roller 103 will not be affected. The transmission shaft of one of the conveying rollers 103 needs to be connected to the output shaft of the motor 202 through a coupling, so that the output shaft of the motor 202 rotates to drive the conveying roller 103 to rotate. The plurality of conveying rollers 103 are connected by belts 203. The wheels are connected by belts 203, so that the rotation of one conveying roller 103 drives multiple conveying rollers 103 to rotate together. Rubber pads need to be installed on the outer walls of the multiple conveying rollers 103. The rubber pads are provided to increase the friction of the steel pipe on the multiple conveying rollers 103, so that the steel pipe will not be skewed when moving on the multiple conveying rollers 103. A support block 201 is welded at the lower part of the motor 202 and on the outer wall of the baffle 102. The motor 202 is fixed to the upper part of the support block 201 by bolts, so that the motor 202 is supported, and the motor 202 is connected by bolts to make it easier to disassemble and assemble.

[0028] like Figure 2 , 3 As shown: the sliding assembly includes a slide rail 301 arranged on the inner wall of a side baffle 102. The slide rail 301 is arranged so that the infrared controller 306 can slide thereon. The slide rail 301 is connected to the inner wall of a side baffle 102 by bolts. The bolt fixation facilitates the disassembly of the slide rail 301 when the position needs to be changed. A slider 302 is slidably connected in the slide groove of the slide rail 301. The slider 302 is arranged so that the infrared controller 306 can move on the slide rail 301 through the slider 302. A support plate 303 is welded on the slider 302. The infrared controller 306 is fixed to the vertical surface of the support plate 303 by bolts, so that the infrared controller 306 is fixed.

[0029] like Figure 3As shown: a pointer 304 is arranged on the vertical surface of the support plate 303 and located on the upper part of the infrared controller 306. The pointer 304 is arranged so that the pointer 304 can be directly pointed to the corresponding scale by adjusting the slider 302, so as to adjust the position of the infrared controller 306. The position of the pointer 304 needs to be set to be parallel to the infrared rays emitted by the infrared controller 306, so that the position of the pointer 304 can be adjusted more accurately. The support plate 303 is set to be a transparent PVC plastic material, so that the pointer 304 is more convenient to observe during adjustment. The pointer 304 is glued by glue. The support plate 303 is fixedly connected to the support plate 303 in such a way that the pointer 304 is more firmly fixed. Threaded holes are provided on the upper and lower lateral surfaces of the support plate 303. Tensioning studs 305 are threadedly connected to the two threaded holes. The tensioning bolts are arranged so that when the slider 302 drives the support plate 303 to move to a certain position, the slider 302 can be fixed by tightening the tensioning studs 305, thereby achieving the purpose of fixing the infrared controller 306. Conversely, the position of the slider 302 can be adjusted by loosening the tensioning studs 305, thereby adjusting the position of the infrared controller 306.

[0030] like Figure 2 , 3 As shown: In summary, the infrared controller 306 is set to use the infrared rays emitted by the infrared controller 306 to detect the position of the steel pipe. The position of the infrared controller 306 can be adjusted by adjusting the slider 302. When the infrared rays of the infrared controller 306 hit the steel pipe, a signal will be sent to the infrared receiver 307. Therefore, the infrared controller 306 and the infrared receiver 307 in this device both use wireless transmission, but the infrared receiver 307 needs to be connected to the hydraulic telescopic rod 105 through a control line, so that after the infrared receiver 307 receives the signal from the infrared controller 306, it transmits it to the hydraulic telescopic rod 105, so that the hydraulic telescopic rod 105 drives the first shear knife 106 to move downward, thereby achieving the purpose of shearing the steel pipe.

[0031] like Figure 1 , 2As shown: the storage assembly includes two fixing plates 401 arranged at the end of one side of the two baffles 102. The fixing plates 401 are arranged to fix the storage box 402. The two fixing plates 401 can be bolted to the vertical surface of the baffle 102 and away from the side of the conveying mechanism. The lower part of the two fixing plates 401 is welded with a storage box 402. The storage box 402 can be arranged to store the cut steel pipes, and one side of the vertical surface of the storage box 402 is fixed by bolts, so that it can be opened. When the cut steel pipe needs to be taken out, it can be opened to facilitate its taking. The side of the bottom plate 101 away from the conveying mechanism is set as an inclined surface, which is set to the inclined surface so that the cut steel pipe can slide into the storage box 402, and the inclination angle of the storage box 402 is set to the same inclination angle as the bottom plate 101, so that the cut steel pipe can fall into the storage box 402 more smoothly. The upper horizontal surface of the slide rail 301 can be engraved with a scale 308 by laser engraving. The scale 308 is set to cooperate with the pointer 304 to adjust the position of the infrared controller 306. Support columns 108 are welded at the four corners of the lower part of the bottom plate 101, so that the entire device is supported.

[0032] The use of the utility model:

[0033] Before the equipment is turned on, it is necessary to debug the position of the infrared controller according to the length of the steel pipe that needs to be cut. Because the slide rail is a certain distance away from the first shearing knife, the distance between the slide rail and the first shearing knife needs to be added for debugging when debugging the infrared controller. For example, when the distance between the slide rail and the first shearing knife is 100cm, the length of the steel pipe to be cut is 300cm, then the distance of the pointer on the support plate needs to be adjusted to 200cm, so that the length of the steel pipe at the cutting position is 300cm. After debugging, start the motor and place the steel pipe on the conveyor roller. Multiple conveyor rollers will drive the steel pipe to move forward, and then the steel pipe will pass between the first shearing knife and the second shearing knife, and then the steel pipe will continue to move forward. After the end of the steel pipe touches the infrared ray of the infrared controller, the infrared controller transmits a signal to the infrared receiver, so that the infrared receiver transmits the signal to the hydraulic telescopic rod through the signal line, so that the hydraulic telescopic rod drives the first shearing knife to move downward, so that the steel pipe is cut by the first shearing knife and the second shearing knife, so that the steel pipe falls and slides into the storage box. At this time, the infrared signal of the infrared controller is interrupted, so that the hydraulic telescopic rod moves upward back to the original position.

[0034] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0035] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
