Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a construction cutting device for a steel bar truss floor slab. Background Technique

[0002] The steel bar truss floor slab is a new type of assembled floor slab, belonging to a kind of un-supported profiled composite floor slab, which is a combination of a steel bar truss and a bottom plate connected into a whole by resistance spot welding. The steel bar truss floor slab has the advantages of convenient installation, less steel bar binding amount, reasonable structure, short construction period, safety and reliability, etc.

[0003] For example, the utility model patent with the application number of 202323455967.2 discloses a construction cutting device for a steel bar truss floor slab. Another set of conveying components assist in conveying the steel bar truss floor slab. When the part of the steel bar truss floor slab to be cut coincides with the cutting port, the staff operates the pressing component to tightly press the steel bar truss of the steel bar truss floor slab and at the same time tightly press the floor slab to prevent the steel bar truss and the floor slab from breaking during cutting. Then, the cutting component is started to perform a transverse cut on the steel bar truss floor slab. After cutting is completed, the other set of conveying components convey the cut steel bar truss floor slab; it includes a workbench, a cutting plate and a cutting port. A cutting plate is arranged inside the workbench, and a cutting port is arranged on the cutting plate. It also includes conveying components, a pressing component and a cutting component. Two sets of conveying components are arranged inside the workbench. The cutting plate is between the two sets of conveying components. A pressing component is arranged at the top of the workbench, and a cutting component is arranged at the bottom of the cutting plate.

[0004] Although the device in the above patent can realize the vertical cutting work of the truss floor slab, in the actual use process, the cutting angle of the cutting tool cannot be adjusted. When the truss floor slab needs to be transversely cut, the vertically cut truss floor slab needs to be placed horizontally and placed on the cutting device to perform the transverse cutting work. However, due to the different lengths of the floor slabs, and most of the transverse lengths are relatively long, it is impossible to horizontally place the longer truss floor slabs on most cutting devices, resulting in the cutting device being unable to perform the transverse cutting work on the truss floor slab, making the cutting device have certain limitations.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Refer to Figures 1-4 As shown in the figure, a construction cutting device for steel bar truss floor slabs provided by the present invention includes a workbench 1. A groove 2 is opened at the top of the workbench 1. Two first brackets 3 are fixedly connected to the bottom of the workbench 1. An electric slide rail 4 is fixedly installed on the tops of the two first brackets 3. An electric slider 5 is slidably connected to the electric slide rail 4. A first motor 6 is fixedly installed on the top of the electric slider 5. The output end of the first motor 6 is fixedly connected to an adjusting plate 7. A cutting knife 8 is rotatably connected to the top of the adjusting plate 7. A driving component is arranged on the adjusting plate 7. A second bracket 9 is fixedly connected to the top of the workbench 1. A controller 23 is arranged on the second bracket 9. A moving component and a pressing and limiting component are arranged on the second bracket 9. Two conveying mechanisms 10 are arranged inside the second bracket 9. Through the coordinated use of structures such as the workbench 1, the groove 2, the electric slide rail 4, the adjusting plate 7, the cutting knife 8, the conveying mechanism 10, and the pressing plate 21, the cutting angle of the cutting knife 8 can be conveniently adjusted according to the cutting angle of the truss floor slab. After the cutting angle is adjusted, its cutting position can be adjusted, which is convenient and fast, avoiding the problem that the truss floor slab cannot be placed on the cutting device for cutting due to its long transverse length, thereby improving the practicability of the cutting device.

[0031] Two support plates 11 are fixedly connected to the second bracket 9. The two support plates 11 are respectively located inside the two conveying mechanisms 10. A number of balls 12 are embedded in the support plates 11. Through the setting of the support plates 11, it can be avoided that the conveyor belt in the conveying mechanism 10 sinks when the pressing plate 21 moves downward to clamp and fix the truss floor slab. Through the setting of the balls 12, the friction between the conveyor belt in the conveying mechanism 10 and the support plates 11 can be reduced.

[0032] The driving component includes a second motor 13, which is fixedly installed on the adjusting plate 7. One end of the output of the second motor 13 and one end of the cutting knife 8 are both fixedly connected with a pulley 14, and a belt 15 is drivingly connected between the outer surfaces of the two pulleys 14.

[0033] A moving groove 16 is formed at the bottom of the second bracket 9. Two moving blocks 17 are slidably connected inside the moving groove 16. The moving component includes a third motor 18 and a threaded rod 19. The third motor 18 is fixedly installed on one side of the second bracket 9. The third motor 18 is a stepping motor and can adjust its rotation speed. The threaded rod 19 is rotatably connected inside the moving groove 16. One end of the output of the third motor 18 is fixedly connected with one end of the threaded rod 19. The threaded rod 19 is threadedly connected with the two moving blocks 17. By the combined use of the moving component and the pressing and limiting component and other structures, when the second motor 13 is started to drive the threaded rod 19 to move and the pressing plate 21 to move synchronously, the pressing and limiting position of the pressing plate 21 can be adjusted. Under the combined action of the hydraulic telescopic rod 20 and the moving block 17 and other structures, the uncut truss floor slab away from the cutting knife 8 and the cut truss floor slab can be pressed and fixed at the same time, improving the stability of the truss floor slab during cutting, and thus improving the cutting quality.

[0034] The pressing and limiting component includes two hydraulic telescopic rods 20, which are respectively fixedly installed at the bottoms of the two moving blocks 17. The telescopic ends of the two hydraulic telescopic rods 20 are both fixedly connected with a pressing plate 21. A plurality of avoiding grooves 22 are formed on the pressing plate 21. Through the setting of the avoiding grooves 22, when the pressing plate 21 moves downward, the steel bar protrusions of the truss floor slab can be moved into the avoiding grooves 22, increasing the contact area between the pressing plate 21 and the truss floor slab, and thus improving the clamping stability.

[0035] Working principle: During work, first adjust the cutting angle of the cutting knife 8 according to the cutting angle of the truss floor slab to be cut. For example, when the truss floor slab needs to be cut horizontally, start the first motor 6 through the controller 23 to drive the adjusting plate 7 to rotate. The adjusting plate 7 drives the second motor 13, the pulleys 14, the belt 15 and the cutting knife 8 to rotate synchronously, so as to adjust the subsequent cutting angle of the cutting knife 8. After adjusting the cutting angle of the cutting knife 8, start the electric slide rail 4 to drive the electric slider 5 to move. The electric slider 5 drives the first motor 6, the adjusting plate 7 and the cutting knife 8 and other structures to move synchronously, so as to adjust the cutting position of the truss floor slab.

[0036] After adjusting the cutting position and cutting angle of the cutting knife 8, place the truss floor slab to be cut on one of the conveying mechanisms 10, start the corresponding hydraulic telescopic rod 20, extend its telescopic end, drive the corresponding pressing plate 21 to move downward, and with the cooperation of the supporting plate 11 and the ball 12, the truss floor slab can be clamped and limited. Then, simultaneously start the two conveying mechanisms 10 and the third motor 18 through the controller 23. The conveying mechanism 10 can convey the truss floor slab towards the cutting knife 8, and when the third motor 18 is started, it drives the threaded rod 19 to rotate. With the cooperation of the moving groove 16, the moving block 17 drives the hydraulic telescopic rod 20 and the pressing plate 21 to move synchronously, so that the pressing plate 21 and the clamped truss floor slab move synchronously. After moving it to the cutting knife 8, start the second motor 13. With the cooperation of the pulley 14 and the belt 15, the cutting knife 8 rotates to cut the floor slab. During the cutting process, when the floor slab is not moved during cutting, by contracting the telescopic end of the hydraulic telescopic rod 20 and moving the pressing plate 21 and then moving the pressing plate 21 downward again, the downward clamping position of the truss floor slab can be adjusted, so that both the uncut floor slab and the cut floor slab can be limited and fixed, improving the stability during the cutting of the floor slab.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
