Description
Technical Field
[0001] The utility model relates to the field of construction engineering, in particular to a steel bar cutting device for construction engineering. Background Technique
[0002] Construction engineering refers to the engineering entity formed by the construction of various housing buildings and their ancillary facilities and the installation activities of pipelines and equipment supporting them. Among them, "housing building" refers to a project with a roof, beams, columns, walls, foundation, and capable of forming an internal space to meet the needs of people's production, residence, study, and public activities. The technical application of construction engineering is also very extensive, such as cast-in-place concrete pile technology, deep foundation pit support technology, concrete and steel bar engineering construction technology, etc. The application of these technologies can improve the quality and efficiency of construction engineering, and at the same time provide the possibility for the innovation and development of construction engineering.
[0003] During the construction process of construction engineering, since the compressive strength of concrete is very excellent, but the tensile strength is relatively weak, therefore, steel bars are added to the building structure to improve the tensile strength of concrete, thereby enhancing the overall structural strength and durability of the building. Among small structures such as construction columns, ring beams, connectors, and embedded parts, steel bars with lengths of 2 - 4 meters and other specific lengths are usually required to increase the stability and integrity of the building. Therefore, it is necessary to process the steel bars to the required lengths in the steel bar processing area.
[0004] In view of the above related technologies, the inventor found that the steel bars are relatively long when transported to the processing area, and it is necessary for workers to process them to specific lengths through a cutting machine and other equipment tools. When cutting the corresponding lengths, the workers will use a ruler or a tape measure to determine the length to be cut on the steel bar according to the engineering drawings or construction requirements, and then use a paint pen, chalk or other marking tools to mark the steel bar, and then carry the marked steel bar to be cut to the jaws of the steel bar cutting machine for cutting operations. This step is not only time-consuming and laborious, but also affects the cutting efficiency of the steel bar. Moreover, due to different diameters of the steel bars, when the thicker steel bars are cut under force, the two ends will be deflected under force. Relying solely on workers to manually carry and cut the steel bars will not only affect the cutting accuracy but also increase the work intensity. Content of the Utility Model
[0005] The main technical problem to be solved by the utility model is to provide a steel bar cutting device for construction engineering, which can improve the cutting efficiency of steel bars, reduce the work intensity of workers cutting steel bars, and improve the cutting accuracy at the same time.
[0006] To solve the above technical problems, a technical solution adopted by the utility model is: to provide a steel bar cutting device for construction engineering, including: a conveying mechanism, a first fixing mechanism, a steel bar cutting machine, a second fixing mechanism, and an adjustable material blocking and conveying device arranged in sequence from left to right;
[0007] The conveying mechanism includes a conveying frame, and a number of conical electric rollers I are rotatably connected at intervals inside the conveying frame. A conical electric roller II rotatably connected to the conveying frame is provided between two adjacent conical electric rollers I, and the conical electric roller I and the conical electric roller II are arranged in opposite directions respectively.
[0008] The adjustable baffle conveying device includes a transmission frame assembly and a positioning baffle assembly, and an adjusting assembly for adjusting the position of the positioning baffle assembly is symmetrically provided at the top of the transmission frame assembly.
[0009] The adjusting assembly includes a slide bar and mounting seats rotatably connected to both sides thereof. The mounting seats are respectively connected to the top of the transmission frame assembly. The slide bar penetrates through and is slidably connected to the bottom end of one side of the positioning baffle assembly, and further includes a locking member for restricting the sliding of the U-shaped frame.
[0010] By adopting the above technical solutions, both ends of the positioning baffle assembly slide on the slide bar, and a suitable position is determined according to engineering drawings or construction requirements so as to limit and partition the ends of the steel bars, so that steel bars of the required length can be obtained during cutting. When the staff transports the steel bars onto the conveying mechanism, the steel bars slide along the inclined surfaces of the conical electric roller I and the conical electric roller II to the intersection axis of the two. At this time, the conical electric roller I and the conical electric roller II rotate to convey the steel bars to the cutting port of the steel bar cutting machine, thereby reducing the working intensity of the staff. During cutting, the fixing mechanism I and the fixing mechanism II respectively fix both ends of the steel bars to prevent both ends of the steel bars from being deflected under force during cutting, and improve the cutting accuracy.
[0011] In a preferred example of the present utility model, it can be further configured that: the positioning baffle assembly includes a U-shaped frame and a limiting plate arranged inside it. An electric push rod I is connected to the top of the U-shaped frame, the extending end of the electric push rod I is connected to the limiting plate, and not less than one auxiliary rod penetrates through the top of the U-shaped frame, and the bottom of the auxiliary rod is connected to the limiting plate.
[0012] By adopting the above technical solutions, the electric push rod I drives the limiting plate to move downward to limit the end of the steel bar, so that the steel bar cutting machine can cut the steel bar to the required length. After cutting, the electric push rod I drives the limiting plate to move upward to convey the cut steel bar to the discharging position.
[0013] In a preferred example of the present utility model, it can be further configured that: the locking member includes an adjusting handle and a threaded rod, and the threaded rod is threadedly connected to the U-shaped frame and one end of it is in contact connection with the surface of the slide bar.
[0014] By adopting the above technical solution, the staff member pushes the positioning baffle assembly to move on the sliding rod, adjusts it to the position corresponding to the cutting length of the steel bar, and by rotating the adjusting handle, drives one end of the threaded rod to be in close contact with the surface of the sliding rod, thereby preventing the positioning baffle assembly from moving, so as to limit the position when positioning the steel bar.
[0015] In a preferred embodiment of the present utility model, it can be further configured that: the transmission frame assembly includes a frame body, and a plurality of conical electric rollers I are rotatably connected at intervals inside the frame body. Between two adjacent conical electric rollers I, there is a conical electric roller II rotatably connected to the inside of the frame body. The conical electric rollers I and the conical electric roller II are respectively arranged in opposite directions, and when the limiting plate is downward, it is located between the conical electric roller I and the conical electric roller II.
[0016] By adopting the above technical solution, the cut steel bars are conveyed by the conical electric roller I and the conical electric roller II, and before cutting, the steel bars are driven to move, so as to limit the steel bars on the same axis of cutting.
[0017] In a preferred embodiment of the present utility model, it can be further configured that: both the fixing mechanism I and the fixing mechanism II include a U-shaped support platform. At both ends of the bottom inside the U-shaped support platform, there are two guiding roller assemblies arranged in opposite directions. Inside the U-shaped support platform, there is a pressing plate. A V-shaped opening is formed at the bottom of the pressing plate. The top of the U-shaped support platform is connected with a hydraulic cylinder, and guiding rods are respectively arranged on both sides of the hydraulic cylinder. One ends of the guiding rods are respectively connected to the pressing plate.
[0018] By adopting the above technical solution, the steel bars to be cut are conveyed by the conveying mechanism and are assisted in guiding by the guiding roller assemblies, so that their ends pass through the cutting port of the steel bar cutting machine, and are stably conveyed and contact the positioning baffle assembly, so as to keep them on the same axis, prevent the ends from being misaligned due to the influence of weight, and at the same time, before the steel bar cutting machine cuts, the pressing plate is driven to move downward by the hydraulic cylinder, so that the V-shaped opening clamps and limits the steel bar, thereby preventing the two ends of the steel bar from being skewed when cutting.
[0019] In a preferred embodiment of the present utility model, it can be further configured that: the guiding roller assembly includes two connecting seats, and a conical roller is rotatably connected between the connecting seats.
[0020] By adopting the above technical solution, the conical rollers are staggered with each other to limit and guide the transmission of the steel bars, so that they always move on the same axis, and the cutting accuracy of the steel bars is improved laterally.
[0021] In summary, the present utility model includes at least one of the following beneficial technical effects of the steel bar cutting device for construction engineering:
[0022] 1. When the staff transports the steel bars onto the conveying mechanism, the steel bars slide along the inclined surfaces of the conical electric roller 1 and the conical electric roller 2 to the intersection axis of the two. At this time, the conical electric roller 1 and the conical electric roller 2 rotate to convey the steel bars to the cutting opening of the steel bar cutting machine, thereby reducing the working intensity of the staff. The two ends of the U-shaped frame slide on the sliding rods, and the appropriate position can be determined according to the engineering drawings or construction requirements to limit and block the ends of the steel bars, so as to obtain steel bars of the required length during cutting and improve the cutting efficiency of the steel bars.
[0023] 2. When the steel bars are cut, the hydraulic cylinder drives the pressing plate to move downward, so that the V-shaped opening clamps and limits the steel bars, effectively fixing the two ends of the steel bars, preventing the two ends of the steel bars from deflecting under force during cutting, improving the cutting accuracy, and under the action of the guide rod, improving the pressing effect of the pressing plate.

[0040] Refer to Figures 1-4, a steel bar cutting device for construction engineering disclosed by the present utility model, comprising: a conveying mechanism 10, a first fixing mechanism 20, a steel bar cutting machine 3, a second fixing mechanism 40, and an adjustable material blocking and conveying device 50 arranged in sequence from left to right. The conveying mechanism 10 includes a conveying frame 11. A plurality of conical electric rollers 12 are rotatably connected at intervals inside the conveying frame 11. A conical electric roller 13 rotatably connected to the conveying frame 11 is arranged between two adjacent conical electric rollers 12. The conical electric rollers 12 and the conical electric roller 13 are respectively arranged in opposite directions. The adjustable material blocking and conveying device 50 includes a transmission frame assembly 51 and a positioning baffle assembly 52. An adjusting assembly 53 for adjusting the position of the positioning baffle assembly 52 is symmetrically arranged at the top of the transmission frame assembly 51. The adjusting assembly 53 includes a slide bar 531 and mounting seats 532 rotatably connected to both sides thereof. The mounting seats 532 are respectively connected to the top of the transmission frame assembly 51. The slide bar 531 passes through and is slidably connected to the bottom end of one side of the positioning baffle assembly 52. It further includes a locking member 533 for restricting the sliding of the U-shaped frame 521. The locking member 533 includes an adjusting handle 5331 and a threaded rod 5332. The threaded rod 5332 is threadedly connected to the U-shaped frame 521 and one end thereof is in contact connection with the surface of the slide bar 531. The model of the steel bar cutting machine 3 is GQ40, GQ50 or GQ60. A V-shaped transmission cross-section is formed between the conical electric rollers 12 and the conical electric roller 13, which corresponds to the cutting port of the steel bar cutting machine 3, and the bottom end of the V-shaped transmission cross-section is flush with the bottom of the cutter head of the steel bar cutting machine 3, ensuring that steel bars of different diameters can be cut when conveyed to the cutting port of the steel bar cutting machine 3.
[0041] The positioning baffle assembly 52 includes a U-shaped frame 521 and a limiting plate 522 arranged inside the U-shaped frame 521. The top of the U-shaped frame 521 is connected to an electric push rod 523, and the extended end of the electric push rod 523 is connected to the limiting plate 522. The top of the U-shaped frame 521 is penetrated by at least one auxiliary rod 524, and the bottom of the auxiliary rod 524 is connected to the limiting plate 522. The transmission frame assembly 51 includes a frame body 511, and the inner side of the frame body 511 is rotatably connected to a plurality of conical electric rollers 512. A conical electric roller 2 513 rotatably connected to the inner side of the frame 511 is provided between two adjacent conical electric rollers 1 512. The conical electric roller 1 512 and the conical electric roller 2 513 are arranged opposite to each other. When the limit plate 522 is downward, it is located between the conical electric roller 1 512 and the conical electric roller 2 513. A V-shaped transmission cross section identical to that of the conical electric roller 1 12 and the conical electric roller 2 13 is formed between the cross sections of the conical electric roller 1 512 and the conical electric roller 2 513. , and on the same axis to ensure that the steel bars are transmitted on the same axis and in the same horizontal position, thereby improving the cutting accuracy. A clearance is formed between the conical electric roller 1 512 and the conical electric roller 2 513. When the electric push rod 1 523 drives the limit plate 522 to move downward, the limit plate 522 moves between the conical electric roller 1 512 and the conical electric roller 2 513 to block the end of the transmitted steel bar, thereby positioning it at the required length, so that the steel bar cutting machine 3 cuts the steel bar to the required length. After cutting, the limit plate 522 is reset upward, and the subsequent cutting of the steel bar is continued through the rotation transmission of the conical electric roller 1 512 and the conical electric roller 2 513. In addition, the thickness of the limit plate 522 is less than the thickness of the blade of the steel bar cutting machine 3, so as to ensure that sufficient clearance is reserved between adjacent steel bars for positioning the steel bars during subsequent transportation, and the bottom of the U-shaped frame 521 does not contact the top of the frame body 511, so that the subsequent staff can adjust its position to improve convenience.
[0042] Both the first fixing mechanism 20 and the second fixing mechanism 40 include a U-shaped support table 21. At both ends of the bottom inside the U-shaped support table 21, there are two oppositely arranged guide roller assemblies 22. Inside the U-shaped support table 21, there is a pressing plate 23. A V-shaped opening 24 is formed at the bottom of the pressing plate 23. A hydraulic cylinder 25 is connected to the top of the U-shaped support table 21. On both sides of the hydraulic cylinder 25, there are guide rods 26 respectively. One ends of the guide rods 26 are respectively connected to the pressing plate 23. The guide roller assembly 22 includes two connecting seats 221, and a tapered roller 222 is rotatably connected between the connecting seats 221; the V-shaped opening 24 corresponds to the V-shaped transmission cross-section formed by the first tapered electric roller 12 and the second tapered electric roller 13. At the same time, the V-shaped surface formed by the intersection of the tapered rollers 222 also corresponds to its V-shaped transmission cross-section, ensuring that while the steel bars are transported on the same axis, they can also be tightly clamped and limited during the cutting process. At the same time, when the hydraulic cylinder 25 drives the pressing plate 23 to move downward, the guide rods 26 improve the stability and pressing effect of the pressing plate 23 to prevent the steel bars from moving.
[0043] The implementation principle of this embodiment is as follows: During use, the staff determines the required cutting length of the steel bars according to the engineering drawings or construction requirements, slides the U-shaped frame 521 on the sliding rod 531, and determines a suitable position. Then, rotate the adjusting handle 5331 to drive one end of the threaded rod 5332 to closely contact the surface of the sliding rod 531, thereby preventing the U-shaped frame 521 from moving. Then, two staff members carry the steel bars to be cut onto the conveying mechanism 10. The steel bars slide along the inclined surfaces of the first tapered electric roller 12 and the second tapered electric roller 13 to the intersection axis of the two, and are transmitted to the cutting port of the steel bar cutting machine 3 and continue to move onto the adjustable material blocking and conveying device 50. Since the tapered rollers 222 intersect to form a V-shaped surface, it effectively prevents the steel bars from being misaligned due to their weight and ensures their conveyance on the same horizontal plane. At the same time, the first electric push rod 523 drives the limiting plate 522 to move downward. When one end of the steel bar contacts the limiting plate 522, the steel bar is positioned. Then, the two hydraulic cylinders 25 drive the corresponding pressing plates 23 to press down, so that the V-shaped opening 24 clamps and limits the steel bar. The steel bar cutting machine 3 cuts the steel bar, and the required length of the steel bar can be obtained. Then, the limiting plate 522 resets, and the first tapered electric roller 512, the second tapered electric roller 513, the first tapered electric roller 12, and the second tapered electric roller 13 continue to rotate, repeating the steel bar cutting operation.
[0044] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, are equally included in the patent protection scope of the present invention.
