[0047] In this embodiment, a plurality of convex ridges 13 are formed on the workbench 1. The plurality of convex ridges are arranged along the width direction of the workbench. Each convex ridge is arranged along the length direction of the workbench. A limiting groove for embedding a threading tube is formed at the top of the convex ridge 13.

[0048] Combination Figure 2 As shown, the convex rib 13 and the workbench 1 form a cutting slit a. The cutting slit is arranged along the width direction of the workbench. The cutting slit runs through the convex rib and the workbench. The position of the cutting slit a corresponds to the position of the saw blade of the electric cutting saw 5. A chip collecting plate 7 is formed at the bottom of the workbench 1. The chip collecting plate 7 is arranged below the plurality of cutting slits a.

[0049] In this embodiment, the chip collecting plate 7 is tilted. The limiting groove is arranged along the length direction of the workbench 1.

[0050] In this embodiment, the width of the limiting groove increases gradually from bottom to top. The cross section of the limiting groove is V-shaped or arc-shaped.

[0051] A bracket 92 is installed in the middle of the workbench 1. In this embodiment, the bracket is a door-shaped bracket. A restraining plate 9 is installed on the bracket so as to be liftable by a second electric hydraulic push rod 91. The restraining plate 9 is used to press against the threading tubes in the limiting grooves of the plurality of convex ridges 13. The restraining plate 9 is along the width direction of the workbench. The length of the restraining plate is adapted to the width of the workbench.

[0052] As a preferred embodiment, a baffle 10 is movably provided on the workbench 1. The baffle 10 is arranged opposite to the flat push plate 8. A third electric hydraulic push rod 101 is connected between the other end of the workbench 1 and the baffle 10. The first electric hydraulic push rod and the third electric hydraulic push rod are respectively arranged along the length direction of the workbench.

[0053] In this embodiment, before cutting the threading tube, the position of the baffle on the workbench is adjusted by the third electric hydraulic push rod, so that the distance from the baffle to the cutting seam is adapted to the length of the tube section of the threading tube after segmentation. Then, multiple threading tubes are respectively embedded in the limiting grooves of the convex ridges. At this time, the first electric hydraulic push rod is extended, so that the flat push plate is pushed toward the baffle to neatly hold the multiple threading tubes, and then the multiple threading tubes are clamped by the baffle and the flat push plate. Afterwards, according to the needs of batch cutting or individual cutting, the first electric cylinder, the second electric cylinder, the third electric cylinder or the fourth electric cylinder is controlled to make the electric cutting saw descend to cut the threading tube.

[0054] The construction method of the batch cutting device for construction line pipes of the present invention comprises the following steps:

[0055] S1. Place a plurality of threading tubes on a workbench 1 and temporarily fix them so that the plurality of threading tubes are respectively disposed under a plurality of electric cutting saws 5 .

[0056] When temporarily fixing, the position of the baffle on the workbench is first adjusted by the third electric hydraulic push rod, so that the distance from the baffle to the cutting seam is adapted to the length of the pipe section of the threading tube after segmentation. Then, multiple threading tubes are respectively embedded in the limiting grooves of the convex ridges. At this time, the first electric hydraulic push rod is extended, so that the flat push plate is pushed toward the baffle to neatly hold the multiple threading tubes, and then the multiple threading tubes are clamped by the baffle and the flat push plate. In this embodiment, the threading tube is temporarily fixed by the baffle and the flat push plate.

[0057] S2. When multiple wire tubes need to be cut in batches at the same time, the first electric cylinder 2 extends to allow the multiple electric cutting saws 5 to descend and cut the multiple wire tubes at the same time. When the first electric cylinder 2 is abnormal, the fourth electric cylinder 61 of the linkage structure extends to allow the push-down beam 62 to press down the upper part of the other end of the multiple bases 4, so that the multiple electric cutting saws 5 descend and cut the multiple wire tubes at the same time.

[0058] S3. When a threading tube needs to be cut, the second electric cylinder 31 and / or the third electric cylinder 41 corresponding to the position of the threading tube is extended to make the electric cutting saw 5 descend and cut the threading tube.

[0059] After the threading tube is cut, the push plate is translated along the length direction of the limiting groove, and the push plate causes the cut threading tube residue in the limiting groove to fall onto the chip collecting plate through the cutting seam. The chip collecting plate is tilted, and a receiving box is connected to the lower side of the chip collecting plate. The residue on the chip collecting plate gradually falls into the receiving box under the vibration of the electric cutting saw when it is working.

[0060] In addition, during cutting, some of the debris dropped by cutting can directly fall onto the chip collecting plate through the cutting slit, and the remaining debris scattered in the limiting groove can be swept into the cutting slit by the flat push plate later.

[0061] In this embodiment, four supporting legs are welded to the bottom of the workbench. All four supporting legs are in contact with the ground. The top surface of the workbench is welded with five convex ridges for placing pipes in a linear array.

[0062] A gantry is fixed on the top surface of the workbench, and a first electric cylinder is fixed on the bottom of the crossbeam of the gantry. The extended end of the first electric cylinder is fixedly connected to a lifting beam. The lifting beam is a rectangular block structure. The left and right ends of the lifting beam are respectively slidably arranged in the slide grooves of the columns of the gantry through sliders.

[0063] Five second electric cylinders are fixed on the bottom surface of the lifting beam. A rectangular block-shaped movable plate is fixed to the extended end of each second electric cylinder. A guide plate is welded to the bottom end surface of each movable plate through two suspension rods.

[0064] Two guide rods are slidably connected to each guide plate. The lower ends of the two guide rods are welded to the top surface of a base. A spiral spring is sleeved on each guide rod for resetting the guide rod upward. There are five bases in total. An electric cutting saw is installed on each base.

[0065] A fourth electric cylinder is fixed on the other side of the bottom surface of the lifting beam. A push-down beam with a rectangular block structure is fixed to the extended end of the fourth electric cylinder. The push-down beam contacts the top surfaces of the five bases.

[0066] A third electric cylinder is fixed to the bottom end surface of each movable plate. The five third electric cylinders are in contact with the top ends of the five bases respectively.

[0067] When five pipes need to be cut at the same time, five electric cutting saws are started and the first electric cylinder is controlled to extend. When the first electric cylinder extends, it can push the lifting beam and the electric cutting saw downward to complete the cutting.

[0068] When the first electric cylinder is damaged, the fourth electric cylinder is controlled to extend. When the fourth electric cylinder extends, it can drive the push-down beam to move downward, and the push-down beam can push the five bases to move downward, so that the five electric cutting saws can move downward synchronously and complete the cutting action.

[0069] When individual cutting is required, the second electric cylinder is controlled to extend, and when the second electric cylinder extends, it can push the movable plate and the electric cutting saw downward to complete the cutting.

[0070] When the second electric cylinder is damaged, the third electric cylinder is controlled to extend. When the third electric cylinder extends, it can push the base to move downward. At this time, the coil spring is in a compressed state, and the electric cutting saw will move downward.

[0071] A positioning part is fixed in the middle of the workbench. The positioning part is composed of a bracket, a first electric hydraulic push rod and a restraining plate. A bracket is fixed in the middle of the workbench by bolts. A first electric hydraulic push rod is fixed on the bracket. A restraining plate with a rectangular block structure is fixed to the extended end of the first electric hydraulic push rod. The restraining plate is located above the convex rib. When the threading tube needs to be fixed, the first electric hydraulic push rod is controlled to extend. When the first electric hydraulic push rod is extended, it can drive the restraining plate downward until the restraining plate is tightly against the outer wall of the pipe.

[0072] Each convex rib is provided with a limiting groove. The limiting groove is a V-shaped hole structure. When placing the threading tube, the threading tube can be directly placed inside the limiting groove, and the threading tube can be limited by the limiting groove of the V-shaped structure.

[0073] The workbench is provided with a cutting slot, which is a rectangular hole-shaped structure, passes through five convex ridges, and is aligned with saw blades on five electric cutting saws.

[0074] A push part is fixed at one end of the workbench. The push part is composed of a first seat body, a second electric hydraulic push rod and a flat push plate. A first seat body with an L-shaped structure is welded at one end of the workbench. A second electric hydraulic push rod is fixed to the left end face of the first seat body. A flat push plate is fixed to the extended end of the second electric hydraulic push rod. The flat push plate is slidably connected to the five convex ridges. The flat push plate contacts the limit groove and the top surface of the workbench.

[0075] When the pipe needs to be pushed, the second electric hydraulic push rod is controlled to extend. When the second electric hydraulic push rod is extended, it can drive the push plate to move to the left. When the push plate moves to the left, it can push the pipe to move to the left. At this time, because the push plate is slidingly connected to the five ridges, the push plate is in contact with the limit grooves and the top surface of the workbench, so the residues in the ridges and limit grooves can be synchronously gathered to the cutting gap.

[0076] A limiting part is fixed on the other end of the workbench. The limiting part is composed of a second seat body, a third electric hydraulic push rod and a baffle. A second seat body with a concave structure is welded to the other end of the workbench. A third electric hydraulic push rod is fixed to the right end face of the inner wall of the second seat body. A baffle with a rectangular block structure is fixed to the protruding end of the third electric hydraulic push rod. The baffle is located on the right side of the pipe. When the pipe contacts the right end face of the baffle, the pipe can be limited by the baffle, which is convenient for subsequent fixed distance cutting.

[0077] During construction, the pipe is directly placed inside the limiting groove. At this time, the pipe can be limited by the limiting groove of the V-shaped structure; when pushing, the second electric hydraulic push rod can be controlled to extend. When the second electric hydraulic push rod is extended, it can drive the push plate to move to the left. When the push plate moves to the left, it can push the pipe to move to the left until the pipe contacts the baffle; when five pipes need to be cut at the same time, five electric cutting saws are started, and the first electric cylinder is controlled to extend. When the first electric cylinder is extended, it can push the lifting beam and the electric cutting saw downward to complete the cutting; when the first electric cylinder is damaged, the fourth electric cylinder is controlled to extend. When the fourth electric cylinder is extended, it can drive the push-down beam to move downward. The push-down beam can push the five bases to move downward, and the synchronous downward movement of the five electric cutting saws is achieved. The cutting action is completed; when separate cutting is required, the single second electric cylinder is controlled to extend, and when the second electric cylinder extends, the movable plate and the electric cutting saw can be pushed downward to complete the cutting; when the second electric cylinder is damaged, the third electric cylinder is controlled to extend, and when the third electric cylinder extends, the base can be pushed downward, at this time the coil spring is in a compressed state, and the electric cutting saw will move downward; when adjusting the limit distance of the pipe, the third electric hydraulic push rod can be controlled to extend and retract; in the process of pushing the plate, because the flat push plate is slidably connected to the five convex ridges, the flat push plate is in contact with the limit grooves and the top surface of the workbench, so the residues in the convex ridges and the limit grooves can be synchronously collected to the cutting gap; when the debris falls through the cutting gap, it will directly fall onto the chip collecting plate, and then be automatically discharged through the chip collecting plate.

[0078] The batch cutting device for construction wire pipes of the present invention, on the one hand, can realize the synchronous movement of multiple electric cutting saws by extending the first electric cylinder, thereby realizing batch cutting. When the first electric cylinder is damaged, the synchronous movement of multiple electric cutting saws can be realized by extending the fourth electric cylinder, and it has high flexibility. On the other hand, a single pipe can be cut individually by extending any one of the multiple second electric cylinders. When the second electric cylinder is damaged, a single pipe can be cut individually by extending any one of the third electric cylinders. It has high flexibility and can perform emergency cutting after the driving component used to move the electric cutting saw is damaged.

[0079] The batch cutting device for construction line pipes of the present invention, on the one hand, only needs to control the extension of the second electric hydraulic push rod. When the second electric hydraulic push rod is extended, it can drive the push plate to move to the left, and when the push plate moves to the left, it can push the pipe to move to the left; on the other hand, because the push plate is slidably connected to the five ridges, the push plate is in contact with the limiting grooves and the top surface of the workbench, so the residues in the ridges and the limiting grooves can be synchronously collected to the cutting gap. Compared with the existing device, the pushing part of the present device can realize both pushing and cleaning.

[0080] The batch cutting device for construction line pipes of the present invention, on the one hand, can collect the residues at the cutting gap for discharge when the push plate moves to the left; on the other hand, when the debris falls through the cutting gap, it will directly fall onto the chip collecting plate and then be automatically discharged through the chip collecting plate, without the need for staff to clean it separately after cutting.

[0081] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
