Description

Technical Field

[0001] The present invention relates to the technical field of manhole cover processing equipment, and in particular to a processing equipment and method for a high-performance manhole cover made of composite material. Background Art

[0002] A manhole cover is a structure used to cover the wellhead of underground facilities such as drains or sewage wells in areas such as roads, sidewalks, and parking lots. The main function of a manhole cover is to ensure the safety of the wellhead and prevent people and vehicles from falling into the well. Manhole covers can be divided into cast iron manhole covers, steel plate manhole covers, composite resin manhole covers, and concrete manhole covers according to their materials. Composite resin manhole covers are made of high-performance composite resin. Compared with manhole covers made of other materials, they are lighter, easier to construct and maintain, and have corrosion resistance. Compared with traditional cast iron manhole covers or steel plate manhole covers, composite high-performance manhole covers have no metal parts and are not worth recycling, so they are not easily stolen. When processing composite high-performance manhole covers, the composite resin material is first placed in a mold, and then a hydraulic press is used to squeeze the mold up and down so that the composite resin material is shaped by the mold. The mold is then heated to shape the composite resin material into a manhole cover. After the manhole cover is taken out of the mold, workers are required to trim the edges of the manhole cover. Although the high-performance composite manhole cover is lighter than the traditional cast iron manhole cover, it is still difficult for workers to move it for a long time, and manual trimming is inefficient, which causes limitations.

[0003] To this end, we propose a processing device and method for high-performance manhole covers made of composite materials. Summary of the Invention

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1: Refer to the attached Figure 1 A processing device for composite material high-performance manhole cover, comprising: a frame 1; a lower mold 11 is fixedly connected to the frame 1; an extrusion hydraulic rod 12 is fixedly connected to the frame 1; an upper mold 13 is fixedly connected to the output end of the extrusion hydraulic rod 12; A trimming mechanism is provided on the frame 1; the trimming mechanism trims the high-performance manhole cover made of composite material extruded and shaped by the upper mold 13 and the lower mold 11.

[0021] Refer to the instruction manual Figure 2 In the present invention, the trimming mechanism includes a mounting block 2, a sliding block 21, a moving block 22 and a trimming tool 23; the mounting block 2 is mounted on the frame 1, and a mounting slot 24 is provided in the mounting block 2; the sliding block 21 is mounted in the mounting slot 24; the moving block 22 is slidably engaged with the sliding block 21, and a trimming motor 25 is fixedly connected to the moving block 22; the trimming tool 23 is rotatably connected to the output shaft of the trimming motor 25; A rack 26 is fixedly connected to the outer side of the sliding block 21 ; two moving motors 27 are symmetrically fixedly connected to the inside of the moving block 22 ; the output ends of the two moving motors 27 are both fixedly connected to a moving gear 28 ; the moving gear 28 is meshed with the rack 26 .

[0022] In the present invention, a groove 3 is formed on the frame 1; the mounting block 2 is fixedly connected in the groove 3; and a transmission roller 31 is provided on the frame 1.

[0023] In the present invention, the sliding block 21 surrounds the composite material high-performance manhole cover, and the staff puts the high-performance composite resin into the lower mold 11, and then controls the extrusion hydraulic rod 12 through the controller to drive the upper mold 13 to move downward, so that the upper mold 13 and the lower mold 11 are closed, and the high-performance composite resin is extruded, so that the high-performance composite resin is shaped by the upper mold 13 and the lower mold 11, and the upper mold 13 and the lower mold 11 are heated, so that the high-performance composite resin is made into a composite material high-performance manhole cover, and then the controller controls the extrusion hydraulic rod 12 to drive the upper mold 13 to move upward, and the staff takes out the composite material high-performance manhole cover and places the composite material high-performance manhole cover on the mounting block 2, and then the controller controls the trimming motor 25 to drive the trimming tool 23 to rotate, and at the same time the moving motor 27 rotates, so that under the engagement of the moving gear 28 and the rack 26, the moving block 22 moves along the sliding block 21, and during the movement of the moving block 22, the trimming tool 23 on the moving block 22 trims the four sides of the composite material high-performance manhole cover; In the present invention, two sets of moving motors 27 and moving gears 28 are provided in the moving block 22, and the two sets are respectively located on both sides of the moving block 22. Therefore, when the moving block 22 moves forward to the gap between the two sliding blocks 21, one set of moving gears 28 disengages from the rack 26, while the other set of moving gears 28 remains in contact with the rack 26, thereby allowing the moving block 22 to continue to move forward. Similarly, when the latter set of moving gears 28 moves to the gap, the former set of moving gears 28 drives the moving block 22 to move forward, thereby enabling the present invention to move between different sliding blocks 21. In the present invention, the mounting block 2 is located in the groove 3, so the mounting block 2 does not expose the surface of the frame 1, and the upper end surface of the mounting block 2 is flush with the transmission roller 31, thereby facilitating the movement of the composite material high-performance manhole cover by the staff; The present invention places the processed composite material high-performance manhole cover in the installation block 2, and the sliding block 21 surrounds the shape of the outer side of the composite material high-performance manhole cover. The moving block 22 moves along the sliding block 21, and at the same time, the trimming motor 25 drives the trimming tool 23 to rotate, so that the trimming tool 23 trims the outer side of the composite material high-performance manhole cover. At the same time, the symmetrically arranged moving motor 27 and moving gear 28 enable the moving block 22 to always be able to move between the sliding blocks 21.

[0024] Refer to the instruction manual Figure 2 and 3 In the present invention, a support groove 4 is radially opened in the mounting block 2; a support rod 41 is slidably connected in the support groove 4; the support rod 41 and the sliding block 21 are hinged; a snap-fit ​​groove 42 is opened in the mounting block 2; the snap-fit ​​groove 42 is connected to the support groove 4, a snap-fit ​​spring 43 is fixed in the snap-fit ​​groove 42, and a snap-fit ​​ring block 44 is slidably connected in the snap-fit ​​groove 42; the end surfaces of the snap-fit ​​ring block 44 and the support rod 41 that are close to each other are both arranged in a tooth shape.

[0025] Refer to the instruction manual Figure 5 In the present invention, a sliding groove 5 is provided on the sliding block 21; two adjustment electric push rods 51 are symmetrically fixedly connected in the moving block 22; a sliding round rod 52 is fixedly connected to the output end of the adjustment electric push rod 51; the two sliding round rods 52 slide in cooperation with the sliding groove 5.

[0026] After all the sliding blocks 21 have been adjusted, the staff member stops pushing the snap ring block 44, so that the snap ring block 44 is engaged with the support rod 41 under the push of the snap spring 43. At this time, all the sliding blocks 21 surround the composite high-performance manhole cover, and the moving block 22 moves around the composite high-performance manhole cover when moving along the sliding block 21. In the present invention, all the sliding blocks 21 constitute the path for the moving block 22 to move. The sliding block 21 of the present invention can surround a composite high-performance manhole cover of any shape, so that the moving block 22 can move around a composite high-performance manhole cover of any shape to trim the composite high-performance manhole cover. In the present invention, the moving block 22 is slidably connected to the sliding block 21 via the sliding rod 52. When the shape or specification of the manhole cover is different, the sliding blocks 21 surrounding the manhole cover have different shapes, so the angle between two adjacent sliding blocks 21 is also different. Therefore, the controller controls and adjusts the electric push rod 51 to push the sliding rod 52 to move, and adjusts the relative positions of the two sliding rods 52 so that the sliding rod 52 can slide with the moving block 22 between the sliding blocks 21 at different angles. Therefore, the moving block 22 of the present invention can move on the moving block 22 surrounding manhole covers of different shapes and specifications. The present invention supports the sliding block 21 through the support rod 41, so that the sliding block 21 is formed into the shape of a high-performance composite manhole cover, and the shape formed by the sliding block 21 can be changed by the support rod 41, so as to correspond to high-performance composite manhole covers of different sizes and specifications. When the moving block 22 moves on the sliding block, it can trim the high-performance composite manhole covers of different sizes and specifications.

[0027] Refer to the instruction manual Figure 1 、 4and 5. In the present invention, a lower moving frame 6 is fixedly connected in the mounting slot 24; a telescopic electric push rod 61 is fixedly connected to the position corresponding to the lower moving frame 6 on the frame 1; the output end of the telescopic electric push rod 61 is fixedly connected to the upper moving frame 68; two moving electric push rods 65 are hinged in the upper moving frame 68 and the lower moving frame 6; the output end of the moving electric push rod 65 is hinged to the same engaging seat 66; an electrode block 62 is fixedly connected to the engaging seat 66 of the upper moving frame 68; an electromagnet block 63 is fixedly connected in the engaging seat 66 in the lower moving frame 6, and a fixing slot 64 is provided in the engaging seat 66 in the lower moving frame 6; an electrode block 62 is also provided in the fixing slot 64; a metal cutting wire 67 is fixedly connected between the two electrode blocks 62. Refer to the instruction manual Figure 6 In the present invention, a blocking electric push rod 7 is fixedly connected to the sliding block 21; and a blocking block 71 is fixedly connected to the output end of the blocking electric push rod 7.

[0028] In the present invention, a flexible contact block 72 is fixedly connected to the blocking block 71; the flexible contact block 72 is made of a flexible material, such as rubber.

[0029] In the present invention, when the composite material high-performance manhole cover is located in the mounting block 2, the controller controls the telescopic electric push rod 61 to push the upper moving frame 68 downward, so that the upper moving frame 68 moves downward with the metal cutting wire 67 and the electrode block 62, passing through the hole on the composite material high-performance manhole cover, and then the electromagnet block 63 on the engaging seat 66 in the lower moving frame 6 generates a magnetic force to attract the electrode block 62 at the lower end of the metal cutting wire 67, so that the electrode block 62 is engaged in the fixing groove 64, and then current is passed into the metal cutting wire 67 to heat the metal cutting wire 67, and then the upper moving frame 68 and the movable electric push rod 65 in the lower moving frame 6 synchronously push the engaging seat 66 to move the metal cutting wire 67, so that the metal cutting wire 67 moves, so that the metal cutting wire 67 melts the burrs in the holes on the composite material high-performance manhole cover during the movement, and the holes on the composite material high-performance manhole cover are trimmed, thereby improving the use effect of the present invention; In the present invention, a blocking electric push rod 7 and a blocking block 71 are provided on the sliding block 21, and the blocking electric push rod 7 pushes up the blocking block 71 so that the blocking block 71 surrounds the high-performance composite manhole cover and clamps the high-performance composite manhole cover. When the moving block 22 moves, the blocking block 71 in front of the moving block 22 moves downward without blocking the trimming tool 23 on the moving block 22. After the moving block 22 moves, the blocking block 71 rises again. In the present invention, a flexible contact block 72 is provided on the blocking block 71. When the flexible contact block 72 contacts the high-performance composite manhole cover, it can be squeezed and maintain pressure between the flexible contact block 72 and the high-performance composite manhole cover, thereby preventing the blocking block 71 from being unable to contact the high-performance composite manhole cover.

Then the staff member stops pressing the snap ring block 44, and the snap ring block 44 fixes the support rod 41. S2. The staff puts the composite material high-performance manhole cover into the sliding block 21, and then blocks the electric push rod 7 to push the blocking block 71 upward to clamp the composite material high-performance manhole cover; S3, the moving block 22 moves along the sliding block 21, and the trimming tool 23 rotates to trim the composite material high-performance manhole cover.
