The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 6 as shown in .

[0029] Embodiment: A rapid cutting device for embedded parts of industrial plants, comprising a convex frame 1, a threaded through hole 102 is provided in the middle of the top horizontal section 101 of the convex frame 1, an adjusting stud 2 is screwed and installed in the threaded through hole 102, a rotating handwheel 3 is fixedly installed on the top of the adjusting stud 2, the lower end of the adjusting stud 2 extends into an adjustment space 4 below the middle of the convex frame 1, a cutting adjustment unit is installed in the adjustment space 4, the top of the cutting adjustment unit is connected to the lower end of the adjusting stud 2, limiting rails 5 are symmetrically installed on the side walls of the adjustment space 4 on both sides of the cutting adjustment unit, the two ends of the cutting adjustment unit are respectively engaged and clamped in the corresponding rail grooves 6 of the limiting rails 5, guide wheel groups are fixedly installed on the bottom of the lower horizontal sections 103 on both sides of the lower part of the convex frame 1, and the two guide wheel groups are symmetrically arranged.

[0030] The industrial plant embedded parts 23 quick cutting device in this design adopts manual propulsion and forward or backward guidance of the guide wheel group to reduce the difficulty of feeding during the cutting process; at the same time, the distance between the operator and the cutting tool is kept within a safe distance range, which is convenient for improving the cutting safety when cutting the embedded parts 23.

[0031] Before cutting, it is necessary to rotate the corresponding rotating handwheel 3 to drive the adjusting stud 2 to rotate. When the adjusting stud 2 rotates, it can drive the cutting adjusting unit that is engaged with it at the bottom to passively rise and fall and make linear motion, ensuring that the cutting component below can be self-locked immediately after moving into place, thereby ensuring the control of the cutting height of the entire cutting component.

[0032] In any of the above schemes, it is preferred that the guide wheel group includes a mounting wheel frame 7 fixedly mounted on the bottom of the lower horizontal section 103, and wheels 8 are respectively mounted at the front and rear ends of the mounting cavity of the mounting wheel frame 7, and both ends of the wheel 8 axle of each wheel 8 are movably inserted in the corresponding rotating holes of the mounting wheel frame 7, and the bottom of each wheel 8 is supported on the factory floor 9.

[0033] The guide wheel group is mainly supported on the ground by the wheels 8 at the bottom. By applying force to the entire device, the entire device can be driven to move in a direction close to or away from the embedded part 23 under the action of the wheels 8.

[0034] In any of the above schemes, it is preferred that the cutting and positioning unit includes a lifting seat 10 arranged at the lower end of the positioning stud 2, and a stepped rotating shaft 12 is installed in cooperation with the stepped circular hole 11 of the lifting seat 10. The small diameter section at the top of the stepped rotating shaft 12 is vertically upward and movably penetrates to the top of the cover seat 13 at the top of the lifting seat 10 and is coaxially fixedly connected with the bottom of the positioning stud 2. The outer diameter of the large diameter section at the bottom of the stepped rotating shaft 12 is greater than the outer diameter of the small diameter section. The cover seat 13 is fixedly connected to the top of the lifting seat 10, and slide seats 14 are fixedly installed on the left and right sides of the lifting seat 10 respectively. The ends of the slide seat 14 are respectively slidably engaged in the corresponding track grooves 6 of the limiting track 5, and a cutting component is fixedly connected to the bottom of the lifting seat 10 through a plurality of connecting columns 15.

[0035] The cutting and positioning unit in the present design is a core working component. When working, it mainly relies on the positioning stud 2 to drive the stepped rotating shaft 12 fixed to it to rotate, so that it can follow the positioning stud 2 to complete the lifting and lowering. During the lifting process, the rotation of the positioning stud 2 is converted into linear motion. Because in the process of rotation, the slide seats 14 on both sides cooperate with the track grooves 6 of the limiting rails 5 to realize a structure similar to that of a lead screw slider, ensuring that the cutting component at the bottom can follow the lifting and lowering of different heights, and at the same time, it can remain locked and positioned after lifting to ensure stability during cutting.

[0036] In any of the above schemes, it is preferred that the cutting component includes a motor frame 16 vertically installed at the bottom of each connecting column 15, a cutting motor 17 is installed in the motor frame 16, and a horizontally arranged disc cutting tool 18 is detachably fixedly installed at the bottom of the motor shaft of the cutting motor 17.

[0037] The cutting component works mainly by starting the cutting motor 17. When the cutting motor 17 is running, it can drive the corresponding disc cutting tool 18 to run, so as to achieve the purpose of controlling it to complete the rapid cutting of the embedded part 23 in front.

[0038] In any of the above solutions, preferably, a gripping handle 19 is fixedly mounted on the outer side walls of the two vertical sections of the convex frame 1 , and a protective cover 20 is fixedly mounted on the outer side wall of the gripping handle 19 .

[0039] By holding the gripping handle 19 with both hands, both hands can exert force and push the entire device to move forward or backward horizontally. During the gripping process, the protective cover 20 can improve the gripping comfort.

[0040] In any of the above schemes, it is preferred that a positioning screw 21 is fixedly installed on the bottom surface of the top horizontal section 101 of the convex frame 1 at the threaded through hole 102 at the top of the adjustment space 4, and an internal thread matching the external thread of the adjustment stud 2 is provided on the inner cavity side wall of the positioning screw 21.

[0041] By increasing the length of the threaded through hole 102 by positioning the screw tube 21 , stability during screwing and installation can be ensured.

[0042] In any of the above solutions, it is preferred that the convex frame 1 is an integrally bent structure.

[0043] The integrally bent convex frame 1 structure can ensure the firmness of the overall structure.

[0044] In any of the above solutions, it is preferred that the lower horizontal sections 103 on both sides of the convex frame 1 are fixedly connected to the top of the corresponding mounting wheel frame 7 through a plurality of quick-release bolts 22 .

[0045] Arranging the entire mounting wheel frame 7 and the corresponding bottom of the convex frame 1 as a quick-release structure can ensure the convenience of disassembly and replacement, and when the wheel 8 of a different size needs to be replaced, it can be quickly replaced.

[0046] Specific working principle: This design adopts manual propulsion and forward or backward guiding of the guide wheel group to reduce the difficulty of feeding during the cutting process; at the same time, it keeps the distance between the operator and the cutting tool within a safe distance range, which is convenient for improving the safety of cutting when cutting the embedded parts 23; before cutting, it is necessary to rotate the corresponding rotating handwheel 3 to drive the adjustment stud 2 to rotate. When the adjustment stud 2 rotates, it can drive the cutting adjustment unit that is engaged with it at the bottom to passively lift and move in a straight line, ensuring that the cutting component below can be self-locked immediately after it moves into place, thereby ensuring the control of the cutting height of the entire cutting component.

[0047] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model. For technicians in this technical field, any replacement improvements or changes made to the implementation methods of the utility model fall within the protection scope of the utility model.
