Description

Technical Field

[0001] The invention belongs to the field of engineering equipment, and in particular relates to a device for processing reserved steel bars during construction. Background Art

[0002] During the construction process, the project is usually not completed in one go, but is instead constructed in multiple phases. Therefore, after the previous phase of construction is completed, in order to ensure docking with the next phase of the project, docking interfaces will be reserved. These docking interfaces such as foundations and walls will have docking steel bars reserved, so that the consistency and integrity of these places can be guaranteed in the next phase of construction.

[0003] Since these reserved steel bars are located outdoors, they are prone to rust and corrosion. Currently, the most economical and effective way to prevent rust is to wrap the reserved steel bars with cement, and then knock off the cement on the steel bars when the next phase of the project starts. Although this method can prevent the steel bars from rusting, the workload is very large when knocking the cement in the later stage. Generally, the reserved steel bars are longer, about 1-2m in length, so when they are knocked, the steel bars are easy to swing. If you are not careful, the knocked-off cement blocks will splash everywhere, and the swinging of the steel bars can easily threaten the safety of the workers, and the risk factor is very high. In addition, most of the steel bars are bent, and after being knocked, many steel bars will bend more. Therefore, when the next phase of the project is built, the steel bars will need to be straightened again, which will be very troublesome for construction.

[0004] In summary, a device is needed to replace manual removal of cement from steel bars and reduce the bending of the steel bars. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems and provide a device for processing reserved steel bars during construction to remove cement from the steel bars and straighten the steel bars during the process of removing cement.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: a device for processing reserved steel bars during construction, comprising a driving tube, a sleeve member that can be sleeved on the steel bars is arranged at the lower end of the driving tube, a plurality of cleaning members that extend into the inner side of the sleeve member to clean the cement on the steel bars are fixedly arranged on the sleeve member, and a driving source is connected to the driving tube;

[0007] A straightening piece is arranged on the top of the driving tube, and the steel bar sleeved in the sleeve piece can pass through the driving tube and the straightening piece upwards, and the straightening piece can straighten the steel bar when rotating.

[0012] As a further improvement of the above technical solution, the sleeve is provided with a notch, and a plurality of reinforcing rings for fastening the sleeve are provided on the surface of the sleeve; the cleaning piece is fixedly arranged on the reinforcing ring.

[0013] As a further improvement of the above technical solution, a protective cover is fixedly provided on the outer side surface of the sleeve.

[0014] As a further improvement of the above technical solution, a protection rod is rotatably arranged on the outer side surface of the shield, and the protection rod has a bend to one side in the direction of the central axis of the shield.

[0015] As a further improvement of the above technical solution, the lifting mechanism includes a lifting rod that can move up and down relative to the driving tube, and the lifting rod is connected to a driving source;

[0016] The upper end of the lifting rod is rotatably connected to the straightening member, the lower end is rotatably connected to the sleeve member, and the sleeve member is spline-connected to the driving tube.

[0017] As a further improvement of the above technical solution, a conveying mechanism is also provided above the driving pipe to clamp the penetrated steel bars and then pull them upwards;

[0018] The conveying mechanism comprises a clamping wheel for clamping the steel bars, and the clamping wheel is connected to a hydraulic cylinder for driving the clamping wheel to clamp the steel bars.

[0019] As a further improvement of the above technical solution, a transmission box is rotatably arranged outside the driving tube, a cavity is arranged inside the transmission box, and the driving tube passes through the cavity inside the transmission box.

[0020] As a further improvement of the above technical solution, a moving device is connected to the transmission box, a telescopic arm of the moving device and the transmission box are rotatably arranged relative to each other, and an adjusting mechanism for driving the transmission box to rotate is arranged on the telescopic arm.

[0021] Beneficial effects of the present invention:

[0022] The present invention provides a device for processing reserved steel bars during construction. Through the set socket parts and cleaning parts, cement on the steel bars can be removed during the rotation process, and the work efficiency is higher, the cement removal effect is more obvious, and the steel bars will not be bent. Under the rotation action of the straightening part, the bent steel bars can be straightened, making the steel bars more convenient to use in the subsequent use and facilitating construction.

[0023] Under the action of the lifting mechanism, the socket and the straightening member can be synchronously driven to move up and down. Due to the guiding effect of the matching port, the expansion part can be contracted and expanded. When the lifting mechanism drives the straightening member and the socket to move downward, the expansion part is contracted, so that the inner tube of the straightening member becomes smaller, so that the bent steel bar can be straightened. At this time, the socket and the cleaning member will impact the cement on the steel bar downward to remove the cement; and when the lifting mechanism drives the socket and the straightening member to rise, since there is a vertical guide section on the matching port, the inclined section and the vertical guide section of the matching port are always in contact during the rising process of the straightening member, but the expansion part will not expand, and the steel bar can be driven to have an upward movement trend, thereby achieving the purpose of automatically conveying the steel bar, and at this time, the socket and the cleaning member move upward to continue to remove the steel bar from which the cement has been removed, so that the cement on the steel bar can be removed more cleanly, so in the process of the lifting mechanism continuously lifting and lowering, the steel bar can be automatically conveyed, and the surface of the steel bar is reciprocated and impact-type cleaned, so that the cement is removed more cleanly.

[0024] The conveying mechanism arranged on the top of the driving tube can convey the steel bars stably, so that the whole device can automatically move on the steel bars and realize automatic cleaning. The automatic conveying of the straightening parts enables the steel bars to be conveyed before they pass through the clamping wheel, thus ensuring the normal operation of the device.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0033] As the instruction manual Figure 1-6 As shown, as a specific embodiment of the present invention, the specific structure of the present invention is: a device for processing steel bars reserved during construction, including a driving tube 10, the driving tube 10 is a pipe that is completely through the inside, and the lower end of the driving tube 10 is provided with a socket 11 that can be sleeved on the steel bar. In this embodiment, the socket 11 is a sleeve structure, and the socket 11 is fixedly provided with a plurality of cleaning members 12 that extend into the inner side of the socket 11 to clean the cement on the steel bar. In this embodiment, the cleaning member 12 is specifically a cleaning rod, which is threadedly connected to the socket 11. The end of the cleaning member 12 is a pointed end, which can directly contact with the cement when cleaning the cement, and the effect is better. The outer side of the driving tube 10 is rotatably provided with a transmission box 18, and the transmission box 18 A cavity is set inside, the driving tube 10 passes through the cavity in the transmission box 18, and is rotatably arranged with the transmission box 18. The transmission box 18 is specifically composed of an upper and lower part merged together. The driving tube 10 is connected with a driving source. In this embodiment, the driving source is a motor fixedly arranged on the outer wall of the driving tube 10, and the output shaft of the motor passes through the inner cavity of the transmission box 18. The output shaft of the motor and the driving tube 10 are respectively provided with mutually meshing gears, and the gears are arranged in the cavity of the transmission box 18. When the motor is started, it will drive the driving tube 10 and the socket 11 to rotate, and the socket 11 will drive the cleaning piece 12 to rotate together. When the steel bar is inserted into the socket 11, the cleaning piece 12 will scrape away the cement on the surface of the steel bar in a rotating state;

[0034] A straightening piece 13 is provided on the top of the driving tube 10. The driving tube 10 and the straightening piece 13 can slide up and down relatively. The steel bars sleeved in the sleeve 11 can pass through the driving tube 10 and the straightening piece 13 upward. The straightening piece 13 straightens the steel bars when rotating.

[0035] As the instruction manual Figure 2 , 3 5, further optimized on the basis of the above embodiment: the straightening member 13 is a sleeve, and the straightening member 13 includes a clamping portion 131 and an expansion portion 132;

[0036] Please refer to the instruction manual Figure 5 Regarding the specific shape of the straightening member 13, the expansion portion 132 is provided with a plurality of through slots 1321, and the expansion portion 132 includes a vertical section 1323 and an inclined section 1322 expanding outward. Under normal circumstances, the vertical section 1323 is vertically downward, and the inclined section 1322 is arranged to be inclined outward;

[0037] Please refer to the instruction manual Figure 3 As shown, the top inner wall of the driving tube 10 is provided with a matching port 101 that matches the expansion part 132, and the matching port 101 is also provided with an upper inclined guide section and a lower vertical guide section. When the straightening piece 13 and the driving tube 10 are matched with each other, the guide section of the matching port 101 can guide the expansion part 132, so that the inclined section 1322 of the expansion part 132 shrinks toward the middle. The clamping part 131 is connected with a lifting mechanism that drives the straightening piece 13 to move up and down. The lifting mechanism drives the straightening piece 13 to move up and down on the outside of the driving tube 10. A guide slider is fixedly provided on the outer surface of the straightening piece 13. The outer surface of the driving tube 10 is fixedly provided with a sliding pin that is slidably connected to the guide slider, and the sliding pin is in a sliding groove on the slider. The inner sliding only realizes the guidance during the up and down movement. When the straightening piece 13 completely enters into the matching port 101, the space of the inner tube of the straightening piece 13 is the smallest. At this time, the inclined guide section of the matching port 101 is in contact with the vertical section 1323, and the vertical guide section is in contact with the inclined section 1322. Therefore, when the inclined section 1322 is always in contact with the vertical guide section of the matching port 101, the size of the inner tube of the straightening piece 13 will not change. Therefore, in the process of the straightening piece 13 moving upward, it will produce the effect of clamping the steel bar and then rising, ensuring that the steel bar can be normally transported upward when passing through the straightening piece 13; a protrusion 133 is provided on the surface of the inner tube of the straightening piece 13, and the protrusion 133 can be in contact with the surface of the steel bar, thereby improving the straightening effect on the steel bar during the rotation.

[0038] As the instruction manual Figure 2As shown, it is further optimized on the basis of the above embodiment: the socket 11 is provided with a notch 111, and the notch 111 is mainly used to discharge the cement that has fallen off when removing the cement. The surface of the socket 11 is provided with a plurality of reinforcing rings 112 for tightening the socket 11, and the reinforcing ring 112 is used to strengthen the strength of the socket 11 to prevent deformation; the cleaning piece 12 is fixedly arranged on the reinforcing ring 112, and the specific cleaning piece 12 passes through the socket 11 and the reinforcing ring 112 at the same time, and is tightened by a nut, so that the cleaning piece 12 inserted into the socket 11 plays a role in removing cement, and the cleaning piece 12 on the outside plays a role in positioning and tightening the reinforcing ring 112; a shield 15 is also fixedly arranged on the outer surface of the socket 11, and the opening of the shield 15 is arranged downward, mainly to block the removed cement blocks and prevent the cement blocks from splashing everywhere.

[0039] As the instruction manual Figure 2 , 4 As shown, the above embodiment is further optimized: a protection rod 20 is rotatably arranged on the outer surface of the shield 15, and a torsion spring is arranged in the protection rod 20. The torsion spring pushes the protection rod 20 to rotate so that the protection rod 20 remains in a vertical state. The protection rod 20 has a bend toward one side of the central axis direction of the shield 15, and the bend at this place is an inclined bend (refer to the attached manual Figure 4 As shown in the figure, the protection rod 20 is provided because after the steel bar comes out of the socket 11, the steel bar will be directly overlapped on the protection rod 20, and the steel bar will be slowly lowered under the rotation of the torsion spring and the protection rod 20, thereby avoiding the impact caused by the huge swing of the steel bar when it just comes out of the socket 11, thereby protecting the workers.

[0040] As the instruction manual Figure 2 , 6 As shown, it is further optimized on the basis of the above embodiment: the lifting mechanism includes a lifting rod 14 that can move up and down relative to the driving tube 10, and the lifting rod 14 is connected to a driving source. In this embodiment, the driving source includes a worm gear reducer, the input end of the reducer is connected to a motor, and the output end is connected to a transmission box. The lifting rod 14 passes through the transmission box, and the two are slidably arranged with each other. A gear connected to the power between the output shaft of the reducer is rotatably arranged in the transmission box, and a rack meshing with the gear is arranged on the lifting rod 14. By controlling the rotation direction of the reducer motor, the reciprocating up and down lifting movement of the lifting rod 14 is controlled;

[0041] The upper end of the lifting rod 14 is rotatably connected to the straightening member 13, and the lifting rod 14 and the straightening member 13 are connected to each other through a connecting block. The connecting block and the straightening member 13 rotate with each other, and a guide column that slides with the connecting block is provided on the top surface of the transmission box 18, and the lower end is rotatably connected to the socket member 11, and the lifting rod 14 and the socket member 11 are also connected through a connecting block. The socket member 11 is splined to the driving tube 10. In this embodiment, the position on the driving tube 10 that is connected to the socket member 11 is transmitted through the connecting surface of the hexagonal prism, that is, the surface on the driving tube 10 that is connected to the socket member 11 is a hexagonal prism, and the sleeve mouth on the socket member 11 that is connected to the driving tube 10 is also a hexagonal prism hole (refer to the attached figure of the specification). Figure 6 As shown), in this way, the driving tube 10 and the sleeve 11 can slide up and down with each other and rotate synchronously. Driven by the lifting mechanism, the sleeve 11 and the cleaning member 12 can reciprocate up and down. When removing cement from the steel bar, it can have a certain impact effect on the cleaned cement along the axis of the steel bar, and realize reciprocating cleaning, making the cleaning cleaner.

[0042] A conveying mechanism is also provided above the driving tube 10 for clamping the steel bars that pass through and then pulling them upwards; in the present embodiment, the conveying mechanism comprises a clamping wheel 16 for clamping the steel bars, and the clamping wheel 16 is provided with two symmetrical ones, and is rotatably arranged on a support frame located at the top of the driving tube 10, and the clamping wheel 16 is connected with a hydraulic cylinder 17 for driving it to clamp the steel bars, and the hydraulic cylinder 17 is fixedly arranged on the support frame, and the output shaft of the hydraulic cylinder 17 and one of the clamping wheels 16 are rotatably connected with each other, and the other clamping wheel 16 is connected with a driving motor for driving it to rotate, and the driving motor and the support frame are fixed to each other, so when the steel bars pass through between the two clamping wheels 16, by controlling to start the hydraulic cylinder 17, one of the clamping wheels 16 pushes the steel bars and the other clamping wheel 16 to clamp each other, and by starting the motor connected to the clamping wheel 16, the motor drives the clamping wheel 16 to rotate, and the whole device can be driven to move on the steel bars, thereby automatically cleaning the cement at different positions on the steel bars.

[0043] As the instruction manual Figure 1As shown, it is further optimized on the basis of the above embodiment: the transmission box 18 is connected with a moving device 19, the telescopic arm of the moving device 19 and the transmission box 18 are arranged to rotate with each other, the telescopic arm can realize horizontal telescopic, horizontal position swing and up and down swing, and the telescopic arm is provided with an adjusting mechanism for driving the transmission box 18 to rotate. In this embodiment, the adjusting device is a hydraulic cylinder hingedly arranged on the telescopic arm, and the output shaft of the hydraulic cylinder and the transmission box 18 are connected with each other. When the hydraulic cylinder is started, it can drive the transmission box 18 to rotate, thereby controlling different angle positions when working.

[0044] The specific use of the present invention is: hold the steel bar to be processed by holding the clamp, start the hydraulic cylinder that controls the rotation of the transmission box 18, align the socket 11 with the steel bar, and feed the steel bar into the socket 11;

[0045] Then, the motor connected to the driving tube 10 is started to drive the driving tube 10, the sleeve 11, and the cleaning member 12 to rotate. The cleaning member 12 removes the cement on the steel bars when rotating. Then, the motor on the worm gear reducer is started to make the lifting rod 14 move up and down reciprocatingly.

[0046] After the steel bar passes through the driving tube 10 and enters the straightening member 13, the steel bar can be straightened under the rotation of the straightening member 13. When the straightening member 13 moves up and down driven by the lifting rod 14, the steel bar can be driven to extend upward to realize the transmission of the steel bar, so that the whole device can move downward on the steel bar.

[0047] After the steel bar passes through the clamping wheel 16, the hydraulic cylinder 17 is started to make the clamping wheel 16 clamp the steel bar, and the motor connected to the clamping wheel 16 is started. The motor drives the clamping wheel 16 to rotate, which can pull the steel bar upward, so that the whole device automatically moves on the steel bar to achieve cleaning of different positions of the steel bar;

[0048] After the cleaning is completed, the steel bar is pulled out from the sleeve 11 and overlapped on the protection rod 20. Under the action of the torsion spring, the protection rod 20 drives the steel bar to swing on the other side, thereby reducing the strong swing impact of the steel bar.
