DETAILED DESCRIPTION

[0049] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0050] Reference Figure 1-16 A split-type double-track cutting and beveling equipment includes a fixed ring 1 and a rotating ring 2 that are arranged in petals and assembled in coordination; the fixed ring 1 and the rotating ring 2 are both two spliced ​​semicircular structures, and connecting parts are respectively arranged on the front and rear sides to assemble them into a complete circular body; the connecting parts can be arranged using conventional mechanisms and will not be described in detail here.

[0051] like Figure 4 、 7, 8; the rear end of the rotating ring 2 is integrally provided with a concentrically arranged gear ring 21 and an inner ring 22; the gear ring 21 and the inner ring 22 are grooved on opposite inner sides to form a track 23; thus, the two are matched to form a double track.

[0052] Correspondingly, the front side of the fixed ring 1 is provided with two layers of concentrically arranged bearing ring supports, each of which is surrounded by a number of bearings 24; each bearing 24 of the inner bearing ring support is in contact with the track 23 of the inner ring 22, and each bearing 24 of the outer bearing ring support is in contact with the track 23 of the gear ring 21.

[0053] Therefore, during driving operation, the two layers of bearing ring supports the gear ring 21 and the inner ring 22 respectively, and the bearing rotates on two tracks. The structure is firm and reliable, and has better stability.

[0054] It is understandable that a plurality of mounting holes are provided through the fixing ring 1 to pass through the locking screw and assemble the bearing; Figure 2 As shown, the mounting holes formed around the fixing ring 1 can be seen.

[0055] In some embodiments, two tool assemblies 3 are mounted on the front side of the rotating ring 2 ; correspondingly, two elastic tool shifting assemblies 4 are mounted on the outer ring side of the fixed ring 1 .

[0056] The two tool assemblies 3 are respectively equipped with a cutting knife and a beveling knife.

[0057] When in use, the two tool assemblies 3 are equipped with tools at the same time, or one of them is selected to be equipped with a tool to meet different operation requirements; when the two tools are assembled at the same time, the bevel cutting operation can be achieved at the same time.

[0058] In some embodiments, two ratchet shafts 42 are provided in the mounting shell 41 of the elastic blade shifting assembly 4 and extend forward.

[0059] Correspondingly, the elastic blade shifting assembly 4 has:

[0060] The two ratchet shafts 42 extend simultaneously to move the two lower tool assemblies 3 to the first state;

[0061] Furthermore, any one of the ratchet shift shafts 42 is extended and the other is retracted, thereby shifting the tool assembly 3 to the second state.

[0062] Therefore, the state can be adjusted according to the working requirements during use; when the two ratchet shift shafts 42 are extended at the same time, the cutting speed is faster.

[0063] Specifically, the ratchet shaft 42 is slidably installed in the mounting shell 41, and a spring is provided at the rear end of the ratchet shaft 42 to push it forward; a corner groove 43 is opened at the upper end of the mounting shell 41, and a lever 44 is provided on the ratchet shaft 42 and is placed in the corner groove 43 to slide.

[0064] Accordingly, the lever 44 slides and adjusts in the corner slot 43 to have a first position in which the ratchet shaft 42 extends forward, and a second position in which the ratchet shaft 42 retracts backward.

[0065] Therefore, it is not only convenient to adjust the working state, but also the spring structure provided on each ratchet shift shaft can absorb the impact force, thereby protecting the equipment and increasing the service life of the elastic knife shift assembly.

[0066] It should be noted that one section of the corner groove 43 extends in the same direction as the telescopic direction of the lever 44, and its length is greater than the moving length of the tool assembly 3 when it collides; at the same time, the other end of the corner groove 43 extends in a direction perpendicular to or at an acute angle to the telescopic direction of the lever 44, and does not generate self-movement after the lever 44 is inserted.

[0067] Preferably, a protective plate 45 is provided at the front upper end of the mounting shell 41 to prevent a person from being injured by the tool assembly 3 when operating the lever 44 .

[0068] In some embodiments, a height adjustment rod 46 is fixedly connected to the lower end of the elastic knife shift assembly 4 to adjust its height to adapt to the position of the ratchet 36 of the knife assembly 3 .

[0069] Correspondingly, the fixing ring 1 is grooved in the radial direction for the height adjustment rod 46 to be inserted into; and a pressing screw is assembled in a hole on the rear side of the fixing ring 1 .

[0070] It should be noted that when using two tools, in order to ensure that the feeding of the two tools does not interfere with each other, the positions of the ratchet wheels 36 of the two tool assemblies 3 are different; accordingly, the positions of the two elastic tool shifting assemblies 4 are respectively matched to one through the height adjustment rod 46; during operation, one elastic tool shifting assembly 4 corresponds to one tool assembly 3, and the operations of the two are independent of each other.

[0071] In some embodiments, the tool assembly 3 includes: a tool seat 31, a tool holder 32 slidably set in the tool seat 31, a slider 33 that is inserted into the rear end of the tool holder 32 to drive it, and a screw rod 34 threadedly engaged with the slider 33; the top end of the screw rod 34 is equipped with a ratchet 36.

[0072] During operation, the ratchet 36 contacts and is shifted with the ratchet shift shaft 42 , and the slider 33 pushes the tool holder 32 downward, thereby achieving automatic tool feeding.

[0073] Furthermore, two thrust bearings 35 are provided at the top of the tool holder 31 to assemble the screw rod 34 , thereby better maintaining the stability of the screw rod 34 .

[0074] Furthermore, a deep groove ball bearing is provided to further improve the stability of the screw rod 34 .

[0075] In some embodiments, a plurality of mounting holes 37 are provided on both sides of the front end of the tool holder 32 to facilitate adjustment of the mounting position. Figure 3 As shown, the two tool assemblies 3 are installed at different positions, resulting in different depths.

[0076] At the same time, the front end of the tool holder 32 is provided with two rows of pressing holes, and the side is provided with one row of side pressing holes, so as to reliably and stably install different tools.

[0077] It is understandable that when installing the tool, it is also necessary to place a suitable pad to cooperate with the pressing screw in the pressing hole to achieve a reliable and stable installation form.

[0078] In some embodiments, a plurality of support components 5 are disposed around the inner side of the fixing ring 1 to adjust the high-precision positioning of the center of the circle.

[0079] The support assembly 5 includes: a support leg 51 and an adjustment structure 52 .

[0080] Specifically, after the adjustment structure 52 passes through the fixing ring 1 from the outside to the inside, a clamping block 53 is provided at its inner end to assemble the support leg 51; thus, by providing the clamping block 53, different support legs 51 can be easily replaced to better adapt to the working environment.

[0081] Preferably, the block 53 includes: a flat plate 531, and step blocks 532 located at the lower parts of both ends of the flat plate 531 and extending outward; accordingly, corresponding slots are provided on the supporting foot 51, thereby forming a larger contact surface and a more reliable installation form.

[0082] Furthermore, protruding blocks 511 are extended from both sides of the lower end of the supporting foot 51 , and anti-slip grooves are provided at the lower ends of the protruding blocks 511 , forming at least two supporting points.

[0083] In addition, the lower end of the support leg 51 can also be configured to fit the arc surface structure of pipes of different diameters to obtain a larger contact surface; however, more specifications of support legs 51 need to be provided accordingly.

[0084] In some embodiments, the adjustment structure 52 includes: a mounting seat 521 fixedly assembled on the outer ring side of the fixing ring 1 , an adjustment screw 522 rotatably set in the mounting seat 521 , and a slide 523 threadedly assembled with the adjustment screw 522 .

[0085] It is understandable that a guide hole is provided on the fixing ring 1 for the slide 523 to penetrate through; after the slide 523 passes through the guide hole, the inner end thereof is fixedly connected to the support leg 51 .

[0086] In addition, in order to prevent the slide 523 from self-rotating during adjustment, a semicircular groove is opened on the outer ring side of the slide 523 corresponding to the inner wall of the guide hole, and a rotation-stopping bar 524 is placed in the semicircular groove.

[0087] In some embodiments, a plurality of lifting ears are arranged around the fixing ring 1 to facilitate the transportation of the equipment.

[0088] It can be understood that a drive component is also included.

[0089] like Figures 1 to 5 The drive assembly is output through the gear and meshes with the ring gear 21.

[0090] Specifically, the drive assembly can adopt: electric, pneumatic or hydraulic power source, which can be selected according to needs.

[0091] When the utility model is used, the petals are opened, the upper part is placed on the pipe, and then the lower part is placed, and they are assembled into a whole through the connecting parts; then, the support component 5 is used to adjust and align; then, the power component is installed, and the position of the tool component 3 and the elastic tool shift component 4 is adjusted and tested; after trial operation and readjustment, the bevel cutting operation can be carried out; during the operation, the tool is automatically fed to complete the bevel cutting.

[0092] The utility model provides a cold cutting method, which will not generate sparks and will not affect the metal properties of the pipe cutting mouth, which is convenient for subsequent welding construction; it also meets the construction needs of flammable and explosive environments, greatly reducing the construction period and project costs; at the same time, the equipment is light, has high cutting efficiency, is easy to operate, has a long service life, is easy to carry, and is convenient for working in various harsh environments such as the field.

[0093] In the present invention, each component is modular in design, and the installation, debugging and maintenance of the equipment are more convenient, which improves work efficiency and can be widely used in the cutting and beveling business of various pipes. The tool assembly 3 is modular in design, and two tool holders can be installed to realize the function of cutting and beveling at the same time. It can also only cut the pipe without beveling, or only beveling without cutting according to the working conditions; it is flexible and convenient, and has good interchangeability. The dual-track design scheme is adopted, the structure is firm and reliable, and has better stability. The elastic tool shift assembly 4 is provided with two ratchet shift shafts 42, which can shift the two tool assemblies 3, with a faster cutting speed. The support assembly 5 is provided with a card block 53, which is convenient for replacing different support feet 51 to better adapt to the working environment. Thrust bearings and deep groove ball bearings are provided to better maintain the stability of the tool holder screw.
