Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a sliding bar type mobile cutting trolley. Background Technology

[0002] In the continuous casting and subsequent processing of steelmaking, billet cutting is one of the key processes. Currently, this operation is widely carried out manually using a handheld gas cutting torch, where operators rely on experience to manually move the torch along the surface of the billet to complete the cut. This method is inexpensive and flexible, and has long been the mainstream choice for many small and medium-sized steel mills.

[0003] However, this traditional method has many inherent defects. First, the cutting quality is highly dependent on personal skills, and uneven cutting surfaces and skewed cuts are easy to occur, which directly affects the subsequent processing quality of the steel billet. Second, the operation process is unstable, and manual operation can easily lead to equipment shaking and uneven walking speed, resulting in cutting interruption or scrapping of the billet.

[0004] Therefore, the industry urgently needs a cutting device that is simple in structure, cost-controllable, and can effectively overcome the above-mentioned drawbacks, so as to upgrade from purely manual operation to semi-automated and mechanized operation. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a sliding bar type mobile cutting trolley to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides a sliding bar type mobile cutting trolley, comprising: Pipe clamp and the first positioning bushing connected thereto; A rotating shaft is sequentially inserted into the first positioning shaft sleeve and the tube clamp; The first positioning bolt passes through the first positioning bushing and is fastened to the rotating shaft so that the rotation angle of the rotating shaft within the first positioning bushing is adjustable and locked. A cutting mechanism, and a mounting mechanism for mounting the cutting mechanism at one end of a rotating shaft; A slide rail base is fixedly connected to the pipe clamp to serve as a moving support for the cutting trolley. The slide rail base slides in conjunction with a laid slide rail, thereby allowing the cutting trolley to move back and forth to perform cutting operations.

[0007] As a preferred technical solution of this utility model, the upper end of the slide rail base forms a fixing surface for supporting and fixing the lower end of the pipe clamp.

[0008] As a preferred embodiment of this utility model, the lower end of the pipe clamp forms a welding area corresponding to the fixing surface.

[0009] As a preferred technical solution of this utility model, the cutting mechanism is a cutting gun, which has a gun head at one end and a movable slide bar at the other end.

[0010] As a preferred embodiment of this utility model, the installation mechanism includes a baffle, one end of which is fixedly connected to the rotating shaft, and the other end is provided with a cutting torch mounting groove, which is used to install the positioning torch head.

[0011] As a preferred technical solution of this utility model, slots adapted to the baffle are provided at both ends of the rotating shaft so that the baffle can be inserted into the slot, and a second positioning bolt sequentially connects the rotating shaft and the baffle.

[0012] As a preferred embodiment of this utility model, the mounting mechanism has two parts symmetrically arranged at both ends of the rotating shaft, so as to install the heads of two cutting guns simultaneously.

[0013] As a preferred technical solution of this utility model, the outer circumferential surface of the rotating shaft is provided with a plurality of slots that are adapted to the end of the first positioning bolt screw to correspond to a plurality of rotation angles.

[0014] The beneficial effects of this utility model are: 1. High cutting precision and stable quality: The precise guidance of the slide rail base and slide rail provides a high-precision straight-line reference for the cutting operation, fundamentally overcoming the shaking and trajectory deviation caused by manual hand operation, thus ensuring a flat and smooth cutting surface with stable and reliable quality.

[0015] 2. Convenient installation and precise positioning of the cutting torch: The cutting torch is fixed by a special installation mechanism, which realizes quick installation and removal and precise positioning of the cutting torch.

[0016] 3. Effortless and efficient operation with wide adaptability: The design features a movable slide bar that can be pushed with one hand, and the cutting angle can be flexibly adjusted via the rotating shaft. Operation is extremely effortless and convenient, greatly improving work efficiency. The design also supports the installation of multiple cutting torches, further meeting the needs of high-efficiency production.

[0017] 4. Excellent safety and maintainability: By designing the tail end of the cutting torch as a movable slide bar, the operator can hold it here and remotely push the carriage, keeping his body away from the high-temperature cutting point and the flying steel slag. This achieves remote isolation between the operator and the high-temperature cutting point, significantly reducing safety risks. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0022] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0023] like Figure 1 and Figure 3As shown, a sliding bar type mobile cutting trolley includes: a pipe clamp 1 and a first positioning sleeve 2 connected thereto, a second positioning sleeve 3 is provided inside the pipe clamp 1, and the second positioning sleeve 3 is fixedly connected to the first positioning sleeve 2; a rotating shaft 6, which passes through the first positioning sleeve 2 and the pipe clamp 1 in sequence; a first positioning bolt 4, which passes through the first positioning sleeve 2 and is fastened to the rotating shaft 6, so that the rotation angle of the rotating shaft 6 in the first positioning sleeve 2 is adjustable and locked; a cutting mechanism, and an installation mechanism for mounting the cutting mechanism on one end of the rotating shaft 6; a slide rail base 9, which is fixedly connected to the pipe clamp 1 to serve as a moving support for the cutting trolley, and the slide rail base 9 slides in cooperation with a laid slide rail 10, so that the cutting trolley can reciprocate to perform cutting operations; The above technical solution solves the problems of unstable trajectory and easy deviation during manual hand-held cutting. Specifically, its working principle is as follows: the rotating shaft 6 is sequentially inserted into the second positioning shaft sleeve 3 within the first positioning shaft sleeve 2 and the pipe clamp 1. The angle of the rotating shaft 6 can be adjusted and locked by tightening the first positioning bolt 4. The cutting mechanism is fixed to one end of the rotating shaft 6 by the mounting mechanism, and its cutting position is adjusted synchronously with the change of the angle of the rotating shaft 6. In use, the slide rail base 9 slides in cooperation with the laid slide rail 10, providing stable moving support for the entire trolley. The operation steps are as follows: first, adjust and lock the angle of the rotating shaft 6 to set the cutting position, and then push the trolley along the slide rail 10 to carry out the cutting operation. This results in a high degree of flatness of the cutting surface, stable and reliable operation, strong structural versatility, high functional integration, and wide applicability.

[0024] Furthermore, in this embodiment, the outer circumferential surface of the rotating shaft 6 is provided with multiple slots that are adapted to the end of the first positioning bolt 4 screw, so as to correspond to multiple rotation angles; The above technical solution solves the problems of difficulty in quickly and accurately positioning the angle during stepless adjustment and the tendency to slip after locking. Specifically, its working principle is as follows: these annularly distributed slots provide multiple preset locking positions for the first positioning bolt 4. The operation steps are: rotate the rotating shaft 6 to the desired angle, so that the end of the screw of the first positioning bolt 4 engages in the corresponding slot, and then tighten the bolt to complete the locking. This achieves fast and accurate multi-level angle adjustment and significantly enhances the reliability of angle locking.

[0025] like Figure 1 and Figure 2 As shown, in this embodiment, the upper end of the slide rail base 9 forms a fixing surface for supporting and fixing the lower end of the pipe clamp 1; the lower end of the pipe clamp 1 forms a welding area 11 corresponding to the fixing surface. The above technical solution solves the problems of insufficient connection strength and easy loosening between the pipe clamp 1 and the mobile chassis. Specifically, its working principle is as follows: the fixed surface provides a stable and reliable installation reference for the lower part of the pipe clamp 1, and the lower end of the pipe clamp 1 is usually fixed here by welding or bolting. The operation steps are as follows: when assembling the trolley, the lower end of the pipe clamp 1 is aligned with the fixed surface and welded to fix it. The lower end of the pipe clamp 1 forms a welding area 11 corresponding to the fixed surface. This welding area 11 is a specific area that has been pre-treated, such as by grinding, to achieve optimal weld joint with the fixed surface of the slide rail base 9. This solves the problem of small contact area and weak connection when the ordinary pipe clamp 1 is directly welded, significantly improves the connection strength between the pipe clamp 1 and the slide rail base 9, and enhances the rigidity and overall stability of the entire cutting trolley structure.

[0026] like Figure 4 As shown, in this embodiment, the cutting mechanism is a cutting gun 13, which has a gun head 1301 at one end and a movable slide bar at the other end. The above technical solution solves the problems of traditional equipment requiring additional push rods, complex structures, and excessively close proximity of the operator to the cutting point. Specifically, its working principle is as follows: the cutting torch 13 itself combines cutting and control functions. Its torch head 1301 is used for cutting, while the movable slide bar at the other end serves as a human-machine interface for the operator to hold and push. The operation steps are as follows: the operator holds the movable slide bar of the cutting torch 13 and can remotely push the entire trolley to move, simplifying the structure, achieving safe operation with separation of human and machine, and significantly reducing labor intensity.

[0027] like Figure 1 and Figure 3 As shown, the mounting mechanism includes a baffle 7, one end of which is fixedly connected to the rotating shaft 6, and the other end is provided with a cutting torch mounting groove 12. The cutting torch mounting groove 12 is used to install and position the torch head 1301, so that when the torch head 1301 is inserted into the cutting torch mounting groove 12, the cutting carriage can be driven by pushing the moving slide bar. The above technical solution solves the technical problems of inconvenient installation, inaccurate positioning, and inability to remotely push the cutting torch 13. Specifically, its working principle is as follows: the baffle 7 serves as a mounting support for the cutting torch 13, and the cutting torch mounting groove 12 on it is used to precisely engage and support the torch head 1301. In use, the torch head 1301 is inserted into the through-hole cutting torch mounting groove 12, which enables quick positioning and fixation, and this through-hole structure does not obstruct the cutting of the material by the flame or cutting jet. The operation steps are: place the cutting torch head 1301 into the cutting torch mounting groove 12, and then push the movable slide bar at the other end of the cutting torch 13 to drive the carriage to cut. This achieves quick and accurate installation and fixation of the cutting torch 13, and naturally forms a labor-saving and safe remote operation mode.

[0028] like Figure 1 and Figure 3 As shown, in this embodiment, the baffle 7 is detachably connected to the rotating shaft 6; specifically, slots adapted to the baffle 7 are provided at both ends of the rotating shaft 6 so that the baffle 7 can be inserted into the slots, and a second positioning bolt 5 sequentially connects the rotating shaft 6 and the baffle 7. The above technical solution solves the problems of inaccurate installation position and unstable connection of the baffle 7. Specifically, its working principle is as follows: the slot structure provides precise positioning for the baffle 7, while the second positioning bolt 5 provides a firm locking force. The operation steps are: insert the baffle 7 into the slot, align the hole, and tighten the second positioning bolt 5 to complete the installation. This ensures the accuracy and repeatability of the baffle 7 installation, while making the connection structure simple, reliable, and easy to assemble and disassemble.

[0029] Furthermore, in this embodiment, the pipe clamp 1 is made of heavy-duty aluminum material; The above technical solution solves the problems of insufficient strength and easy deformation of ordinary pipe clamps 1, while heavy-duty steel pipe clamps 1 are too bulky. Specifically, its working principle is as follows: the heavy-duty design ensures sufficient strength and rigidity to securely clamp the cutting mechanism; while the aluminum material gives the components lightweight characteristics. There are no special requirements for operation; it can be used in the conventional way. While ensuring that key components have extremely high structural strength, it effectively reduces the overall weight of the cutting carriage, making it easier to move, and also has good corrosion resistance.

[0030] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0031] This utility model aims to cover all such substitutions, modifications, and variations that fall within its protection scope. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within its protection scope.
