Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and in particular to a bridge truss steel cutting equipment. Background Art

[0002] A truss bridge is one that uses a truss as the primary load-bearing superstructure. A truss bridge generally consists of a main girder, upper and lower horizontal longitudinal connecting systems, portal frames, intermediate cross braces, and a deck system. Truss bridges are mostly constructed of steel. In a truss, the chords are the members that form the outer perimeter of the truss, including the upper and lower chords. The members connecting the upper and lower chords are called webs, which are further categorized as diagonal or vertical depending on their orientation.

[0003] The webs of a truss are connected to their corresponding chords at both ends to ensure the strength of the entire truss. Because the lengths and orientations of the webs vary at different locations, the truss steel must be cut to the specified lengths during construction. Furthermore, the shape of the web ends must match the shape of the corresponding chord sides. This ensures that, after the truss is connected, the gap between the web ends and the chords meets the requirements, ensuring sufficient connection stability.

[0004] When existing cutting equipment is used to cut truss steel, the existing cutting structure adopts a plate-type blade structure, so the end shape of the cut truss steel is a corresponding straight structure. The chord of the truss includes arc and straight types. When the chord is straight, the side of the chord is a straight structure. The end of the web can be cut into a corresponding inclined end according to the inclination to ensure the fit between the web and the chord. However, if Figure 1 and Figure 2 When the chord is in an arc shape, the end of the straight structure of the web will make the connection between the web and the chord a line contact, and there will be a gap between the chord and the web. The insufficient contact area leads to a lack of connection stability and strength between the web and the chord. Summary of the Invention

[0005] The technical problem solved by the present invention is that the end of the truss steel cut by the existing truss steel cutting equipment is a straight structure. When the chord is an arc structure, the end of the straight structure of the web will make the connection between the web and the chord a line contact, and there is a gap between the chord and the web. The insufficient contact area leads to a lack of connection stability and connection strength between the web and the chord.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0009] A clamping mechanism, which is provided on the cutting platform and is used to clamp the truss steel to be cut;

[0010] A cutting mechanism, the cutting mechanism being fixedly arranged on the cutting platform and comprising a cutting power assembly, a cutting tool holder and a cutting tool head;

[0011] The cutting power assembly is drivingly connected to the cutting tool holder, the cutting tool head is detachably connected to the cutting tool holder, and the structure of the cutting tool head matches the shape of the installation position portion of the web member on the chord member.

[0014] As a further solution of the present invention: the locking structure includes a locking plate, a locking notch is formed on the locking plate, a locking block is arranged in the locking notch, the width of the locking block matches the distance between two adjacent connecting rods, and the distance between two opposite locking blocks matches the height of the connecting rod; locking teeth are fixedly provided on the upper and lower sides of the connecting rod.

[0015] As a further solution of the present invention: a reference bracket is provided on the cutting tool holder, and a contact head is provided at one end of the connecting rod away from the cutting head, and the contact head is tapered.

[0016] As a further solution of the present invention: a connecting hole and an adjustment notch are provided on the cutting platform, the adjustment notch is arc-shaped, the clamping mechanism is arranged on the base, the bottom surface of the base is fixedly provided with a connecting column matching the connecting hole and the adjustment notch, and the base is provided with a fixing structure for locking the base.

[0017] As a further solution of the present invention: the position of the adjustment notch is provided with an indicating scale.

[0018] As a further solution of the present invention: the clamping mechanism includes a first plate and a first linear drive assembly, the first plate is slidably connected to the base, and the first linear drive assembly drives the first plate.

[0019] As a further solution of the present invention: the clamping mechanism also includes a second plate and a second linear drive component, the second plate is provided with a clamping structure, the second plate is slidingly connected to the first plate, the second linear drive component drives the second plate, and the first linear drive component and the second linear drive component are arranged vertically.

[0020] As a further solution of the present invention: the cutting power assembly is a linear drive structure.

[0021] The bridge truss steel cutting equipment according to the present invention has at least one of the following technical effects:

[0022] The truss steel cutting equipment of the present application sets the cutting head into a structure that matches the shape of the truss chord, so that the corresponding web end shape can be formed when cutting or processing the web end, so that the web can fit the side of the arc-shaped chord when connecting, ensuring sufficient contact area, thereby ensuring the stability and connection strength of the connection part of the web and chord.

[0023] By configuring the cutting head as a split structure, the device can form a stepped structure for the ends of the truss steel webs. The connecting line of the protruding parts between adjacent steps matches the curvature of the side of the chord, and is used to contact the side of the chord, increasing the size of the contact area between the web and the chord, and ensuring stability. At the same time, due to the stepped end structure, the protruding part of the end of the web can undergo slight deformation during assembly, reducing the impact of cutting errors, ensuring the contact area between the web end and the chord, and reducing the difficulty of assembly. At the same time, after the assembly is completed, due to the presence of a certain gap at the step position, it can be used to release a certain amount of stress, which can prevent the web from directly and completely abutting the side of the chord, resulting in the stress being directly transferred to the chord, thereby affecting the stability of the chord. The gap position can be filled with glue to prevent rust during installation. The strength of the glue at the gap position is relatively low compared to the truss steel itself, and can be used to release stress to prevent excessive stress from being transferred to the main beam.

[0039] 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. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0041] In the description of the present invention, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0042] The two ends of the web members 13 of the truss are fixedly connected to the corresponding chords through connecting plates and bolts to ensure the strength of the entire truss. Since the layout directions (i.e., the degree of inclination) of the web members 13 at different positions are different, it is necessary to process the shape of the end of the truss steel to form a shape that can fit the chord as much as possible, so as to ensure that the overall structure has sufficient connection stability after the truss is assembled. However, since the existing cutting structure adopts a plate-type blade structure, the cutting ports of the ends of the cut truss steel are all straight structures. Figure 1 、 2 When the chord is in an arc shape, the end of the straight structure of the web 13 will make the connection between the web 13 and the chord linear contact, and there will be a gap between the chord and the web 13. The insufficient contact area will lead to a lack of connection stability and connection strength between the web 13 and the chord.

[0043] To address the aforementioned issues, the applicant has proposed a truss steel cutting device. The cutting head 5 is configured to match the shape of the truss chord. This allows the web member 13 to be shaped accordingly when cutting or processing the end of the web member 13. This allows the web member 13 to conform to the side of the curved chord during connection, ensuring sufficient contact area and, consequently, ensuring stability and strength of the connection between the web member 13 and the chord. Furthermore, the applicant has configured the cutting head 5 as a split structure, allowing the structure of the cutting head 5 to be adjusted according to the desired shape. Specifically, the shape of the cutting path formed by the cutting head can be adjusted, allowing the cut shape of the truss steel end to more closely match the target shape, increasing the contact area and enhancing the connection stability and strength. The device processes the ends of the truss steel web members 13 into a stepped structure. The line connecting the protrusions between adjacent steps matches the curvature of the chord side, allowing for contact with the side of the chord, increasing the contact area between the web member 13 and the chord and ensuring stability. At the same time, due to the stepped end structure, the protruding portion of the end of the web member 13 can undergo slight deformation during assembly, reducing the impact of cutting errors, ensuring the contact area between the end of the web member 13 and the chord, and reducing the difficulty of assembly. Furthermore, after assembly is complete, the presence of a certain gap at the stepped position can be used to release a certain amount of stress, preventing the web member 13 from directly and completely abutting the side of the chord, which would result in the complete transfer of stress directly to the chord and thus affect the stability of the chord. During installation, the gap can be filled with glue to prevent rust. The strength of the glue at the gap is lower than that of the truss steel itself, which can be used to release stress and prevent excessive stress from being transferred to the main beam.

[0044] See also Figure 3-5 As shown, the present invention is a bridge truss steel cutting device, comprising a device body 1, a clamping mechanism 2, and a cutting mechanism. The device body 1 is provided with a cutting platform; the clamping mechanism 2 is disposed on the cutting platform and is used to clamp the truss steel to be cut; the cutting mechanism is fixedly mounted on the cutting platform and comprises a cutting power assembly 3, a cutting tool holder 4, and a cutting head 5; the cutting power assembly 3 is driven and connected to the cutting tool holder 4, and the cutting head 5 is detachably connected to the cutting tool holder 4. The structure of the cutting head 5 matches the shape of the portion where the web member 13 is mounted on the chord member.

[0045] See also Figure 3-4In one embodiment of the present invention, the device body 1 serves as the main structure of the cutting device, providing support and mounting locations for related structures. A cutting platform is provided on the device body 1. The cutting platform can be configured as a tabletop structure, serving as a support platform for cutting or processing the ends of the truss steel. A clamping mechanism 2 is provided on the cutting platform to clamp the truss steel to be cut. The clamping mechanism 2 can include a first plate and a first linear drive assembly. The clamping structure for clamping the truss steel can be provided on the first plate. The first plate and the cutting platform can be slidably connected via a slide rail, a slider structure, or other related structure. Specifically, a first slide rail can be fixedly provided on the cutting platform, and a first slider matching the first slide rail can be fixed to the bottom surface of the first plate. The first slider and the cutting platform can be slidably connected in cooperation with the first slide rail. The first linear drive assembly is connected to the first plate, driving the first plate toward or away from the cutting mechanism, thereby feeding or shifting the truss steel. The first linear drive assembly can be a hydraulic cylinder structure, a screw rod structure, or other linear drive structure. Furthermore, the clamping mechanism 2 can also be provided with a second plate and a second linear drive assembly, the second plate being located above the first plate. In this case, the clamping structure is provided on the second plate, the second plate is slidably connected to the first plate, the second linear drive assembly drives the connection to the second plate, and the first linear drive assembly and the second linear drive assembly are arranged vertically, thereby realizing the displacement of the truss steel in different directions, which is convenient for processing the truss steel. Specifically, the second plate and the first plate can be slidably connected by a slide rail, a slider structure or other related structures. Specifically, a second slide rail can be fixedly provided on the first plate, and a second slider matching the second slide rail can be fixed on the bottom surface of the second plate, and the second slider cooperates with the second slide rail to slide and connect the second plate and the first plate. The second linear drive assembly drives the connection to the second plate, and is used to drive the second plate to move linearly, thereby realizing the feeding or displacement of the truss steel. The second linear drive assembly can be a hydraulic cylinder structure or a screw rod structure or other linear drive structure.

[0046] See also Figure 3-6In one embodiment of the present invention, the cutting mechanism is fixedly mounted on the cutting platform and includes a cutting power assembly 3, a cutting blade holder 4, and a cutting head 5. The cutting power assembly 3 is rotatably connected to the cutting blade holder 4, driving the cutting blade holder 4 and the cutting head 5 to cut the truss steel. The cutting action can be a punching or pressing method that directly cuts the truss steel, or a gradual cutting method that forms the end shape based on the remaining allowance, whereby the end position is gradually cut to form the corresponding end shape. Alternatively, existing cutting equipment can be used to pre-cut the end to form a linear structure, and then the web member 13 end is processed to form the target shape. The cutting power assembly 3 can be a rotary drive structure or a linear drive structure, preferably a linear drive structure that drives the cutting head 5 up and down. The cutting head 5 is detachably connected to the cutting blade holder 4, allowing for easy removal and replacement of the cutting head 5 to process web member 13 ends of different shapes. The structure of the cutting head 5 matches the shape of the web member 13 where it is mounted on the chord. By configuring the cutting head 5 to match the shape of the target position of the chord, the shape of the end of the web member 13 formed by cutting matches the shape of the corresponding position of the chord. This ensures that the end of the web member 13 fits the chord (especially the curved chord) during assembly of the chord and web member 13, thus avoiding the problem of insufficient connection stability and poor connection strength at the connection point between the web member 13 and the chord due to a small contact surface. The cutting head 5 can be a punching head structure or a grinding head structure, without limitation.

[0047] See also Figure 6-9 In one embodiment of the present invention, the cutting head 5 includes a plurality of cutting heads. A connecting rod 6 is provided between the cutting head and the cutting frame 4. The connecting rod 6 is slidably connected to the cutting frame 4, and a locking structure for locking the position of the connecting rod 6 is provided on the cutting frame 4. The plurality of cutting heads are movably connected to the cutting frame 4 via the connecting rod 6. The plurality of cutting heads form an integral cutting head 5 and determine the shape of the end of the web 13 that can be cut. When in use, the positions of the different cutting heads are adjusted according to the target shape of the web 13 to be cut, so that the intersection points of adjacent cutting heads (the intersection points of the side contours of adjacent cutting heads, such as Figure 7) matches the outline of the corresponding position of the chord, and the corresponding position is the position where the web member 13 is to be installed. The connecting rod 6 is then locked by the locking structure to fix the position of the cutting head, and then the end of the web member 13 is cut. After cutting, a stepped structure can be formed, and the outer end connecting line contour of the protruding part matches the connecting line contour of the intersection of adjacent cutting heads, that is, the outer end connecting line contour of the protruding part matches the outline of the corresponding position of the chord, so that the protruding part of the step structure can contact the side of the chord, thereby making the original single-line contact become the existing multi-position contact, thereby ensuring that the end of the web member 13 can better fit the side of the chord, increasing the contact surface between the web member 13 and the chord, and improving the connection stability between the two, as well as the connection strength of the web member 13 and the chord connection position. At the same time, due to the stepped end structure (i.e., the tip of the protruding portion at the end of the web member 13), the tip of the protruding portion of the end of the web member 13 can undergo subtle deformation during assembly, reducing the impact of cutting errors, ensuring the contact area between the end of the web member 13 and the chord, and reducing the difficulty of assembly. Furthermore, after assembly, the presence of a certain gap at the stepped position can be used to release a certain amount of stress, preventing the web member 13 from directly and completely abutting the side of the chord, which would result in the complete transfer of stress directly to the chord and thus affect the stability of the chord. During installation, the gap can be filled with glue to prevent rust. The strength of the glue at the gap is lower than that of the truss steel itself, which can be used to release stress and prevent excessive stress from being transferred to the main beam.

[0048] See also Figure 6 In one embodiment of the present invention, a placement groove 7 can be opened on the side of the cutting head, and a reinforcement strip can be set in the placement groove 7. Alternatively, a reinforcement strip can be formed by convexly protruding from the side of one cutting head, and a side of a cutting head adjacent to the cutting head can be concavely formed to form a placement groove 7. The reinforcement strip and the placement groove 7 are slidably matched to enhance the strength and stability of the cutting head in different cutting directions. Figure 6 The cutting head can be a punching head structure or a grinding head structure provided with a blade.

[0049] See also Figure 10In one embodiment of the present invention, the locking structure can be a pin, screw, or other structure for locking the position of the connecting rod 6. For example, the locking structure includes a locking plate 8 having a locking notch formed therein. A locking block 9 is disposed within the notch. The width of the locking block 9 matches the distance between two adjacent connecting rods 6, and the distance between two opposing locking blocks 9 matches the height of the connecting rod 6. A plurality of locking teeth are fixedly disposed on the upper and lower sides of the connecting rod 6. Specifically, the locking notch is larger than the overall outer dimensions of the connecting rod 6 and the outer locking teeth. To adjust the position of different cutting heads using the connecting rod 6, the locking plate 8 is adjusted so that the larger portion of the locking notch matches the position of the connecting rod 6. In this case, the locking block 9 is positioned between two adjacent connecting rods 6. After the position of the connecting rod 6 is adjusted, the locking plate 8 is pushed to position the locking block 9 within the connecting rod 6. The engagement of the locking block 9 with the locking teeth restricts the movement of the cutting heads, securing the cutting head 5, which is composed of multiple cutting heads, for processing the ends of the web member 13, thereby increasing the subsequent contact area with the chord member.

[0050] See also Figure 11-12 In one embodiment of the present invention, the cutting platform may be provided with a connection hole and an adjustment notch 11, wherein the adjustment notch 11 is arc-shaped, and the clamping mechanism 2 is provided on a base 12. The bottom surface of the base 12 is fixedly provided with a connection column that matches the connection hole and the adjustment notch 11, that is, one connection column is located in the connection hole, and the other connection column is located in the adjustment notch 11. The base 12 is provided with a fixing structure for locking the base 12. The fixing structure may be a pin, a screw, etc., which can be used to lock the position connected in the adjustment notch 11. By providing the adjustment notch 11, the angle of the base 12 can be adjusted, and then the inclination state of the truss steel clamped on the base 12 can be adjusted, and the angle between the truss steel and the cutting head 5 can be changed, thereby changing the size and shape of the notch of the step mechanism cut by the end of the web 13. Furthermore, an indicator scale is provided at the position of the adjustment notch 11, so that the adjustment status can be observed more intuitively. At the same time, a cutting blade can be set next to the cutting mechanism to complete the pre-cutting of the web 13 to facilitate the subsequent formation of a specific shape. The inclination degree of the shape pre-cut at the end of the web 13 can be changed by adjusting the angle of the base 12.

[0051] See also Figure 12In one embodiment of the present invention, the cutting tool holder 4 is provided with a reference bracket 10, which can be used to secure a reference template. A conical contact head is provided at the end of the connecting rod 6, distal from the cutting head. During use, a reference template matching the shape of the web member 13 at its connection location on the chord (or the shape of the end of the web member 13 to be machined) is secured to the reference bracket 10. The connecting rod 6 is then adjusted so that the contact head abuts the reference template, and the connecting rod 6 is then locked, allowing for quick adjustment and positioning of the cutting head.
