Technical Field
[0001] The invention relates to the technical field of cutting equipment, and in particular to a multifunctional cutting equipment for producing pipe jacking machine parts. Background Art
[0002] The pipe jacking machine is a modern engineering construction equipment that can complete the laying of underground pipelines across roads, railways, rivers, ground buildings, underground structures, etc. without excavating the surface layer. The components of the pipe jacking machine include the front steel shell, the rear steel shell, the cutting mechanism, the mud delivery and discharge mechanism and other components.

[0016] In addition, the movable carrier is in a higher position to lift the thinner plates being cut, preventing the thinner plates from falling from a height and causing bending of corners. When cutting the plates for producing pipe jacking machine components, the thinner plates fall from the top of the cutting table. The movable carrier lifts the cut thinner plates under the traction of the spring to prevent the taller plates from falling from a higher position and causing bending and folding of corners. As the number of plates increases, when the movable carrier moves downward and encounters a limit plate, the outer end of the movable carrier tilts downward to make the thinner plates being cut fall from a lower position, thereby ensuring the integrity and flatness of the plates during cutting, improving the efficiency of later processing such as welding of pipe jacking machine components, and having multiple functions to improve the quality of cutting.

The top of the rotating member 203 is meshed with each other, and a storage groove 204 is provided on the top of the rotating member 203; an anti-skid bracket 205 is slidably installed inside the storage groove 204, wherein a rubber pad is installed on the top of the anti-skid bracket 205; a support plate 206 is installed on the output end of the driving cylinder on the top of the positioning base plate 202; a movable plate 207 is rotatably installed on the top of the support plate 206; a connecting member 208 is installed on the top of the side end of the movable plate 207; the top of the connecting member 208 passes through the bottom of the rotating member 203 and is connected to the bottom of the anti-skid bracket 205; two positioning grooves 209 are provided on the front side of the top of the cutting table 1; a rotating lever 2010 is rotatably installed inside the positioning groove 209;A rubber strip is provided on the outer side of the rotating lever 2010, and the side end of the rotating lever 2010 passes through one end of the cutting table 1, and one end of the rotating lever 2010 is connected to the output end of the servo motor at one end of the cutting table 1 through a chain group. When cutting the plate for producing the pipe jacking machine parts, the large plate is placed on the top of the fixed bracket 2 and the supporting carrier 201. The length sensor of the top edge position of the fixed bracket 2 and the top of the cutting table 1 positions and measures the size of the plate to detect whether there is a deviation in the position of the plate. When the cut plate has a large deviation, the driving cylinder on the top of the positioning base plate 202 drives the support plate 206 to move upward, and the top of the support plate 206 drives the connecting piece 208 at the top of the side end of the movable plate 207 to move upward, and the top of the connecting piece 208 passes through the bottom of the rotating member 203 to support the anti-skid bracket 205 to move upward inside the storage groove 204, so that the anti-skid bracket 205 is against the bottom of the plate, and the movable plate 207 continues to move upward to a certain position to push The movable rotating member 203 moves upward, so that the plate moves upward to reduce the friction with the supporting carrier 201. After the rotating member 203 moves upward, the serrated structure at the bottom of its outer side meshes with the gear at the output end of the driving motor at the bottom of the supporting carrier 201. The driving motor drives the rotating member 203 to rotate, and the rotating member 203 drives the anti-skid bracket 205 to rotate. Then the movable plate 207 rotates on the top of the supporting plate 206, so that the anti-skid bracket 205 drives the plate to adjust the angle, so that the cutting position on the plate is in a horizontal position with the cutting knife assembly 102. After the rotating member 203 and the anti-skid bracket 205 move downward, the servo motor at one end of the cutting table 1 drives the two rotating levers 2010 to rotate inside the positioning groove 209 through the chain group, and the rubber strip outside the rotating lever 2010 drives the plate to move to the cutting knife assembly 102 for cutting, reducing the manual adjustment of the horizontal angle, saving time and labor, and intelligent detection, improving the accuracy of plate cutting, and improving the quality of pipe jacking machine parts production. ;
[0026] Embodiment 3, on the basis of embodiment 1, a guide slot 1 3 and a guide slot 2 301 are provided on the rear side of the cutting table 1; the guide slot 1 3 and the guide slot 2 301 are T-shaped structures, and the guide slot 1 3 is located on the outside of the guide slot 2 301; a spring is installed on the top of the guide slot 2 301, and a guide slider 1 302 is installed inside the guide slot 2 301 through the spring sliding movement; a movable carrier plate 303 is rotatably installed between the two guide sliders 1 302; a limiting protrusion is provided at the bottom of the inner end of the movable carrier plate 303, The top of the movable carrier 303 is an inclined structure, and a movable groove 304 is provided on the side of the movable carrier 303; a spring is installed on the top of the guide slide groove 1 3, and a guide slider 2 305 is installed inside the guide slide groove 1 3 through the spring sliding movement; the guide slider 2 305 is a T-shaped structure, and a positioning rod 306 is installed between the two guide sliders 2 305; the positioning rod 306 is a cylindrical structure, and the positioning rod 306 is slidably installed inside the movable groove 304; a limit plate 307 is installed at the bottom of the rear side of the cutting table 1; the limit plate A movable carrier plate 303 is installed on the top of 307. When cutting the plate for producing the pipe jacking machine parts, the guide slide 1 302 and the guide slide 2 301 are driven by the springs inside the guide slide 1 302 and the guide slide 2 305 to drive the movable carrier plate 303 to a higher position. When the cut plate falls on the movable carrier plate 303, the plate is lifted, especially the thinner plate, to prevent the thinner plate from falling from a higher position to the ground and causing the corner bending and deformation. As the number of plates increases, the movable carrier 303 is pressed downward, and the bottom inner end of the movable carrier 303 is engaged with the limit plate 307. The plates continue to press the movable carrier 303, and the slightly inclined surface on the top of the movable carrier 303 drives the movable carrier 303 to rotate between the two guide sliders 302. The positioning rod 306 moves inside the movable groove 304, so that the movable carrier 303 is inclined and the plates slide to the ground, reducing the problem of edge angle bending and deformation caused by the drop from a higher position, thereby improving the quality of plate processing.
[0027] The working principle of this embodiment is as follows: when in use, the plate is placed on the fixed bracket 2 and the supporting carrier 201, and the length sensor at the top edge position of the fixed bracket 2 and the top of the cutting table 1 measures the size of the plate to detect whether there is a deviation in the position of the plate. When the cut plate has a large deviation, the driving cylinder at the top of the positioning base plate 202 drives the support plate 206 to move upward, and the support plate 206 drives the connecting piece 208 at the top of the side end of the movable plate 207 to move upward to support the anti-skid bracket 205 to move upward in the storage groove 204, and the anti-skid bracket 205 is against the bottom of the plate, and the movable plate 207 continues to move upward to push the rotating member 203 to move upward. After the rotating member 203 moves upward, the serrated structure at the bottom of its outer side is meshed with the gear at the output end of the driving motor at the bottom of the supporting carrier 201, and the driving motor drives the rotating member 203 to make the anti-skid bracket 205 drive the plate to adjust the position, and the cutting position on the plate is in a horizontal position with the cutting knife assembly 102. After the rotating member 203 and the anti-skid bracket 205 move downward, the servo motor The chain group drives two rotating levers 2010 to move the plate to the cutting knife assembly 102 for cutting. When the driving assembly 101 drives the cutting knife assembly 102 to move downward, the two ends of the cutting knife assembly 102 drive the rotating rod 105 at the bottom of the traction side plate 104 and the spring on its outer side to drive the positioning plate 1010 to move. The positioning plate 1010 pulls the flip plate 106 to flip downward at the front side of the driving assembly 101 through the traction rope 1011. At the same time, the airflow generated by the air pump enters the jet hood through the guide pipe 107. The impurities on the cutting part of the plate are blown out from inside 108 to be cleaned, and the cut plate falls on the movable carrier 303. As the number of plates on the movable carrier 303 increases, the movable carrier 303 is pressed to move downward, and the bottom of the inner end of the movable carrier 303 is engaged with the limit plate 307. The movable carrier 303 rotates between the two guide sliders 302, and the positioning rod 306 moves in the movable groove 304. The movable carrier 303 is inclined to make the plate slide to the ground, reducing the problem of bending and deformation of the edge angle of the plate.
