Description

Technical Field

[0001] The invention relates to the technical field of metal pipe processing, in particular to an auxiliary comprehensive processing device for a sewage protection pipe. Background Art

[0002] A sewage pipe, as the name implies, is a pipe used to transport sewage. In order to prevent damage to the sewage pipe, a protective metal pipe is generally installed on the outside of the sewage pipe to increase the strength of the sewage pipe. During the construction process, due to measurement errors and errors generated during the laying process, the size of the protective pipe deviates. At this time, the protective pipe needs to be cut. After the protective pipe is laid, two adjacent protective pipes usually need to be welded to avoid sewage leakage and ensure the strength of the protective pipe. If there are burrs at the incision, it will affect the welding quality and thus affect the overall strength of the protective pipe. Therefore, in order to facilitate the cutting of the protective pipe and pre-welding treatment, a sewage protection pipe auxiliary comprehensive processing device is needed.

[0003] The Chinese invention patent with the announcement number CN114211041B discloses a pipe cutting device, which belongs to the field of mechanical manufacturing technology. The pipe cutting device includes: a lifting platform, a fixing structure and a cutting structure, the lifting platform includes a top plate and a bottom plate; the fixing structure includes a driving motor, a connecting plate, an elastic chuck, a limiting shaft, a conical sleeve and a nut, the driving motor is fixed on the top plate, the output shaft of the driving motor is fixedly connected to one end face of the connecting plate, the other end face of the connecting plate is fixedly connected to one end of the elastic chuck, the outer surface of the middle part of the elastic chuck is provided with an annular groove, the elastic chuck is penetrated with a limiting shaft, and one end of the limiting shaft is fixedly connected to the connecting plate.

[0004] The above technical solution can ensure the smoothness of the cutting, but if this technical solution is used to process the protective pipe, other equipment is needed to grind the cut after cutting. Most of the protective pipe cutting work requires measurement at the construction site before cutting. Carrying more equipment will cause inconvenience. Therefore, this technical solution is less practical when used for the processing of sewage protection pipes. Summary of the invention

[0090] The first transmission belt 404 is sleeved on the first pulley 402 and the second pulley 403 .

[0091] Further, the grinding assembly includes:

[0092] An annular seat 607, the annular seat 607 is fixed on the side wall of the portal frame 302, and the axis of the annular seat 607 coincides with the axis of the transmission shaft 502;

[0093] A connecting plate 601, the connecting plate 601 is rotatably sleeved on the annular seat 607;

[0094] Two connecting shafts 605, both of which are rotatably disposed on the side wall of the connecting plate 601, and each connecting shaft 605 is fixedly sleeved with a grinding wheel 606;

[0095] The mounting plate 603 is fixed to the transmission shaft 502 , and sandpaper 604 is fixed to the side wall of the mounting plate 603 .

[0096] The transmission shaft 502 rotates, driving the mounting plate 603 to rotate, thereby causing the sandpaper 604 to rotate;

[0097] The position of the support frame 103 is adjusted by an electric slide, so that the protection tube on the fixed ring 104 on the support frame 103 can approach and contact the sandpaper 604, and the sandpaper in the rotating state 604 can be used to grind the cut end face of the protection tube.

[0098] Furthermore, the grinding assembly also includes:

[0099] A first transmission wheel 801, the first transmission wheel 801 is fixedly sleeved on the transmission shaft 502;

[0100] Two second transmission wheels 803, the two second transmission wheels 803 are respectively fixedly sleeved on the two connecting shafts 605;

[0101] A second transmission belt 804, which is sleeved on the first transmission wheel 801 and the two second transmission wheels 803;

[0102] Four tension wheels 802 are rotatably disposed on the side wall of the connecting plate 601, and each tension wheel 802 is in conflict with the second transmission belt 804 (such as Figure 4 shown).

[0103] The tensioning wheel 802 enables the second transmission belt 804 to be in close contact with the first transmission wheel 801 and the two second transmission wheels 803 , thereby ensuring the normal rotation of the two connecting shafts 605 .

[0104] Furthermore, it also includes:

[0105] Two connecting rods 602, the two connecting rods 602 are fixed between the two connecting plates 601;

[0106] A fixing block 701, the fixing block 701 is fixed on the side wall of the door frame 302;

[0107] An electric push rod 702, which is fixed on the top of the fixed block 701;

[0108] Two connecting blocks 704, one of which is fixed to the connecting plate 601, and the other is fixed to the telescopic end of the electric push rod 702;

[0109] The connecting rod 703 has two ends which are rotatably connected to the two connecting blocks 704 respectively.

[0110] When the electric push rod 702 is turned on, the electric push rod 702 makes the connecting plate 601 rotate around the annular seat 607 through the connecting rod 703 and the two connecting blocks 704, so that the two grinding wheels 606 on the same connecting plate 601 are in an up-and-down state;

[0111] Then, the two cut protection tubes are controlled to move closer by an electric slide, so that the protection tubes can enter between the two grinding wheels 606 (such as Figure 8 As shown), the electric push rod 702 then drives the connecting plate 601 to reset. When the grinding wheel 606 and the protective tube collide, the switch of the electric push rod 702 is turned off. At this time, the outer wall of the cutout of the protective tube contacts the upper grinding wheel 606 (as shown in FIG. Figure 8As shown), the inner wall of the cutout of the protective tube contacts the grinding wheel 606 below, and the end face of the cutout of the protective tube contacts the sandpaper 604. The switch of the motor 401 is turned on again. When the motor 401 works, it drives the transmission shaft 502 to rotate, so that the sandpaper 604 rotates, thereby grinding the end face of the cutout of the protective tube.

[0112] Furthermore, two symmetrically arranged handles 108 are fixed to the side walls of the two movable rings 107 .

[0113] The specific working method is: when in use, the support frame 103 is moved by controlling the electric slide, and the two support frames 103 are brought close together by the electric slide;

[0114] The protective tube to be cut is passed through the two fixing rings 104, and the protective tube is moved in the fixing rings 104 to adjust the position between the protective tube and the cutting blade 501. When the protective tube is moved to a suitable position, the staff can rotate the screw rod 105 through the knob to cooperate with the threaded hole to realize the movement of the screw rod 105 and the rubber plate 106. When all the rubber plates 106 on the screw rod 105 are tightly in contact with the protective tube, the fixing rings 104 and the protective tube are fixed, and then the tube cutting work can be carried out;

[0115] It is worth noting that: when the screw rods 105 and the rubber plates 106 are used to fix the protective tube, it is necessary to ensure that before fixation, the rubber plates 106 in each fixing ring 104 are distributed in a circular state (the screw rods 105 can be rotated and the rubber plates 106 can be in contact with the fixing ring 104 to ensure that the rubber plates 106 in the fixing ring 104 are distributed in a circular state). Subsequently, during the fixing process, the screw rods 105 rotate the same number of times, thereby making the rubber plates 106 on the screw rods 105 move the same amount, so that the axis of the protective tube can coincide with the axis of the fixing ring 104.

[0116] When cutting the pipe (the pipe cutting state is as follows Figure 7 As shown in the figure, the switch of the motor 401 is turned on. When the motor 401 is working, the transmission shaft 502 is driven to rotate through the first pulley 402, the second pulley 403 and the first transmission belt 404, thereby driving the cutting blade 501 to rotate. Then the switch of the hydraulic push rod 301 is turned on. When the hydraulic push rod 301 is working, the door frame 302 is driven to descend, thereby causing the cutting blade 501 to descend. When the cutting blade 501 and the protective tube collide, the hydraulic push rod 301 continues to apply pressure to the cutting blade 501, and the cutting blade 501 rotates to achieve the tube cutting work;

[0117] During the pipe cutting process, the worker needs to rotate the movable ring 107 through the handle 108, thereby rotating the cutting blade 501 along the surface of the protection pipe to complete the final cutting of the protection pipe;

[0118] After cutting, the support frame 103 is first driven to move by the electric slide, so that the protective tubes at both ends after cutting can be separated from each other along with the support frame 103. When the two protective tubes are separated, the hydraulic push rod 301 is operated to make the door frame 302 continue to descend, and the switch of the electric push rod 702 is turned on. When the electric push rod 702 is working, the connecting plate 601 is rotated around the annular seat 607 through the connecting rod 703 and the two connecting blocks 704, so that the two grinding wheels 606 on the same connecting plate 601 are in an up-and-down state, and then the two fixing rings 1 are moved again by the operation of the electric slide. 04 are close to each other, and the connection plate 601 is driven to reset through the operation of the electric push rod 702. During the reset process of the connection plate 601, when the grinding wheel 606 and the protection tube collide, the switch of the electric push rod 702 is turned off. At this time, the outer wall of the cutout of the protection tube collide with the upper grinding wheel 606, the inner wall of the cutout of the protection tube collide with the lower grinding wheel 606, and the end face of the cutout of the protection tube collide with the sandpaper 604. The switch of the motor 401 is turned on again. When the motor 401 works, it drives the transmission shaft 502 to rotate, so that the sandpaper 604 rotates, and the end face of the cutout of the protection tube is polished (the polishing state is as shown in FIG. 1 ). Figure 8 shown);

[0119] During the rotation of the transmission shaft 502, the two connecting shafts 605 are driven to rotate by the first transmission wheel 801, the second transmission belt 804 and the two second transmission wheels 803, so that the two grinding wheels 606 rotate, thereby achieving the grinding work of the outer wall and the inner wall of the cutout of the protection tube;

[0120] During the processing of the cutout of the protection tube, it is still necessary to rotate the door frame 302 around the protection tube through the handle 108 so that all positions of the cutout of the protection tube can be polished.

[0121] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
