Description

Technical Field

[0001] The present application relates to the field of steel cage manufacturing technology, and in particular to a method for manufacturing an eccentric steel cage for a large-diameter anti-sliding column. Background Art

[0002] The main role of the steel cage is the same as the stress of the longitudinal steel bars of the column, which mainly plays a shearing role. The concrete has high compressive strength but low tensile strength. It plays a restraining role on the pile concrete, so that it can withstand a certain axial tension. The eccentric steel cage is mainly used in the slope anti-sliding support structure. Since the main potential force in the later stage is the lateral thrust from the mountain on the side of the mountain, its load is an eccentric load, so an eccentric steel cage is needed to make the center of gravity of the steel cage tilted toward the side close to the mountain to ensure the normal use of the anti-sliding column.

[0003] With respect to the above-mentioned related technologies, the applicant believes that the current production of eccentric steel cages is rather complicated and is generally assembled manually with a hanger, but this is time-consuming and labor-intensive, and the production efficiency is low. Summary of the invention

[0004] In order to improve the problem of low manufacturing efficiency of eccentric steel cages, the present application provides a method for manufacturing an eccentric steel cage for a large-diameter anti-sliding column.

[0005] The present application provides a method for manufacturing an eccentric steel cage for a large-diameter anti-sliding column using the following technical solutions:

[0006] A method for manufacturing an eccentric steel cage for a large-diameter anti-sliding column comprises the following steps:

[0007] Cutting steps: Load the main steel bar onto the quantitative cutting device, and cut the main steel bar into a preset length through the quantitative cutting device. After cutting, the length of each cut main steel bar needs to be measured. The error between the length of the main steel bar after cutting and the preset length is -15cm to +5cm;

[0008] Grinding and assembling steps: Grind and thread the ends of the main steel bars, thread the ends of the main steel bars after grinding and threading with a connecting sleeve, and butt the two sections of the main steel bars after grinding and threading with the connecting sleeve;

[0009] Reinforcement connection steps: bend the reinforcement into a circle, and weld multiple main steel bars and multiple reinforcement bars together to form a reinforcement cage skeleton. The main steel bars placed on the reinforcement cage near the mountain side need to be welded together, while the main steel bars on the reinforcement cage far from the mountain side only need a single one;

[0010] Roll welding steps: Load the steel cage frame onto the roll welding machine, and then wind the spiral reinforcement around the outside of the steel cage frame along the length direction of the steel cage frame. When the roll welding machine is running, workers need to hold a spot welding machine to weld and reinforce the position where the spiral reinforcement and the main steel bar are attached;

[0021] By adopting the above technical solution, the clamping assembly can clamp the main steel bar on the rolling shaft, and then the driving assembly can move the clamping assembly clamping the main steel bar in the direction close to the touch cutting mechanism for a distance; after moving a distance, the stripping assembly changes the clamping assembly from the clamping state to the loosened state, and then the driving assembly returns the clamping assembly to the original position, and then a new round of clamping of the main steel bar is performed, and then the driving assembly drives the clamping assembly clamping the main steel bar to move in the direction close to the touch cutting mechanism for a distance; after repeating the above many times, the main steel bar can be directly allowed to slowly enter the touch cutting machine, thereby achieving a convenient and intuitive effect of driving the main steel bar to move automatically.

[0048] A method for making an eccentric steel cage for a large diameter anti-sliding column, referring to Figure 1 , including the following steps:

[0049] Cutting step: the main steel bar is loaded onto the quantitative cutting device 1, and the main steel bar is cut into a preset length by the quantitative cutting device 1. After cutting, the length of each cut main steel bar needs to be measured, and the error between the length of the main steel bar after cutting and the preset length is -15cm to +5cm;

[0050] Grinding and assembling steps: Grind and thread the ends of the main steel bars, thread the ends of the main steel bars after grinding and threading with a connecting sleeve, and butt the two sections of the main steel bars after grinding and threading with the connecting sleeve;

[0051] Reinforcement connection steps: bend the reinforcement into a circle, and weld multiple main steel bars and multiple reinforcement bars together to form a reinforcement cage skeleton. The main steel bars placed on the reinforcement cage near the mountain side need to be welded together, while the main steel bars on the reinforcement cage far from the mountain side only need a single one;

[0052] Roll welding steps: Load the steel cage frame onto the roll welding machine, and then wind the spiral reinforcement around the outside of the steel cage frame along the length direction of the steel cage frame. When the roll welding machine is running, workers need to hold a spot welding machine to weld and reinforce the position where the spiral reinforcement and the main steel bar are attached;

[0053] The steps of installing the anti-slip surface are as follows: a steel plate is placed on the inner wall of the steel cage on the mountain side, the steel plates are stacked in multiple layers and each layer is welded to each other, and the stacked steel plates are welded in the steel cage, while only one or two layers of steel plates are welded on the inner wall of the steel cage away from the mountain side;

[0054] Steel cage reinforcement steps: Weld a tripod inside the inner circle of the steel cage along the length direction of the steel cage.

[0055] Combination Figure 1 , 2 The quantitative cutting device 1 includes a lifting support mechanism 2, a touch cutting mechanism 3, a lateral pushing mechanism 4 and an automatic collecting mechanism 5; the lateral pushing mechanism 4 is arranged between the lifting support mechanism 2 and the touch cutting mechanism 3, the lifting support mechanism 2 is used to lift the main steel bar in the vertical direction, that is, the main steel bar is placed on the ground, and the lifting support mechanism 2 can lift the main steel bar from the ground to the position to be cut; the lateral pushing mechanism 4 is used to push the main steel bar on the lifting support mechanism 2 into the touch cutting mechanism 3; the touch cutting mechanism 3 is used to automatically and accurately cut the main steel bar according to the preset length after the main steel bar enters the inside, and the automatic collecting mechanism 5 is used to collect and store the main steel bar after cutting.

[0056] When cutting the main steel bars, the main steel bars are directly placed on the lifting support mechanism 2, and then the main steel bars are lifted up by the lifting support mechanism 2 so that the main steel bars are at a height that can enter the touch cutting mechanism 3; then the main steel bars are pushed into the touch mechanism by the lateral pushing mechanism 4, and at this time the main steel bars are cut according to the preset length by the touch cutting mechanism 3, and after cutting, they are directly stored in the automatic collection mechanism 5; after this setting, the main steel bars do not need to be cut manually when cutting, which improves the degree of automation in cutting the main steel bars.

[0057] Combination Figure 2 , 3The lifting support mechanism 2 includes a lifting cylinder 21, a top frame 22 and a rolling shaft 23. The lifting cylinder 21 is installed on the ground and the piston rod of the lifting cylinder 21 extends vertically upward. The top frame 22 is installed on the top of the piston rod of the lifting cylinder 21, and the rolling shaft 23 is rotatably arranged on the top frame 22. It should be noted that rollers are also arranged vertically and rotatably at both ends of the rolling shaft 23 on the top frame 22. The arrangement of the rollers can prevent the main steel bars from falling off the rolling shaft 23. Therefore, the lifting cylinder 21 can be directly started to extend the piston rod of the lifting cylinder 21, so that the main steel bars on the rolling shaft 23 can be lifted vertically upward, making the lifting of the main steel bars more convenient. In order to make the main steel bars more stably on the rolling shaft 23, multiple sets of lifting support mechanisms 2 are arranged along the feeding direction of the main steel bars, that is, the main steel bars can have support points on multiple rolling shafts 23, and the entire main steel bars can be more stable.

[0058] Reference Figure 2 , 4 The lateral pushing mechanism 4 includes a pushing frame 6, a clamping assembly 7, a stripping assembly 8 and a driving assembly 9; the pushing frame 6 is installed between the lifting support mechanism 2 and the touch cutting mechanism 3, the driving assembly 9 is installed on the pushing frame 6, the clamping assembly 7 is installed on the driving assembly 9, and the driving assembly 9 is used to drive the clamping assembly 7 to move toward the touch cutting mechanism 3; the clamping assembly 7 is used to clamp the main steel bar on the rolling shaft 23, the stripping assembly 8 is installed on the clamping assembly 7, and the stripping assembly 8 is used to forcibly separate the clamping ends of the clamping assembly 7 so that the clamping assembly 7 no longer clamps the main steel bar.

[0059] The operating mechanism for pushing the main steel bar to move into the touch cutting mechanism 3 is as follows: first, the main steel bar located on the rolling shaft 23 is clamped by the clamping component 7, and then the driving component 9 drives the clamping component 7 to move the main steel bar along the length direction of the main steel bar itself, so that the main steel bar gradually enters the touch cutting machine; after moving a certain distance, the clamping component 7 can no longer move forward. At this time, the stripping component 8 is used to forcibly change the clamping component 7 from the state of clamping the main steel bar to the state of releasing the main steel bar, and then the driving component 9 drives the clamping component 7 to return along the original path to the side close to the lifting support mechanism 2; then the clamping component 7 is clamped to the other outer wall of the main steel bar, and the above steps are repeated to move the main steel bar into the touch cutting mechanism 3 step by step.

It is worth noting that the two rubber liners 74 can fit the main steel bars tightly from both sides of the main steel bars, and the surface of the rubber lining 74 is provided with a vertical blocking strip, which can increase the friction between the main steel bars and the rubber lining 74 and reduce the probability of slipping.

[0061] The worker first manually pushes a section of the main steel bar between the two extrusion blocks 73. At this time, the two extrusion blocks 73 are temporarily restricted by the stripping assembly 8 and are not close together; then the stripping assembly 8 is released, and under the action of the elastic force of the extrusion spring 72 itself, the two extrusion blocks 73 are driven to move towards each other, so that the two rubber liners 74 directly contact the outer wall of the main steel bar on both sides, forming a clamping force; and the setting of the edge slider 75 can improve the movement stability of the extrusion block 73 in the through cavity 711.

[0062] Reference Figure 2 The driving assembly 9 includes a telescopic cylinder 91, the extension direction of the piston rod of the telescopic cylinder 91 is consistent with the moving direction of the main steel bar, and the end of the piston rod of the telescopic cylinder 91 is connected to the end of the movable plate 71; in the present embodiment, the piston rod of the telescopic cylinder 91 is toward one side of the touching and cutting mechanism 3, that is, when the telescopic cylinder 91 is extended, it will directly drive the movable plate 71 to move along the length direction of the main steel bar toward the touching and cutting mechanism 3; similarly, when the telescopic cylinder 91 is contracted, it will move the movable plate 71 away from the touching and cutting mechanism 3.

[0063] Combination Figure 2 , 4The stripping assembly 8 includes a bracket 81, a stripping cylinder 82 and a stripping block 83; the bracket 81 is mounted on the movable plate 71, the stripping cylinder 82 is mounted on the bracket 81 and the piston rod of the stripping cylinder 82 extends vertically downward, the stripping block 83 is mounted on the piston rod of the stripping cylinder 82, the cross-sectional shape of the lower part of the stripping block 83 is an isosceles triangle, and the block walls of the two extrusion blocks 73 facing each other are provided with inclined contact surfaces 731, and the two inclined contact surfaces 731 form a triangular groove, and the triangular groove and the stripping block 83 face each other in the vertical direction. That is, when the two rubber liners 74 clamp the main steel bars, the triangular groove will be directly formed and can be visually seen, and the tip of the stripping block 83 in the shape of an isosceles triangle will face vertically downward.

[0064] When it is necessary to change the two rubber liners 74 from the fitted state to the separated state, the stripping cylinder 82 is directly started, so that the piston rod of the stripping cylinder 82 extends vertically downward, thereby driving the stripping block 83 to be inserted into the triangular groove of the two inclined contact surfaces 731; as the stripping block 83 continues to move, the stripping block 83 will forcibly separate the two inclined contact surfaces 731, and at this time the stripping block 83 will be between the two extrusion blocks 73, separating the two extrusion blocks 73 and the two rubber liners 74; and the main steel bar between the two rubber liners 74 is no longer clamped by the rubber liners 74, thereby achieving the effect of more conveniently separating the two extrusion blocks 73 and the two rubber liners 74. It is worth noting that in order to improve the extrusion sliding performance between the stripping block 83 and the inclined contact surface 731, polytetrafluoroethylene is covered on the inclined contact surface 731 and the contact wall of the stripping block 83.

[0065] Reference Figure 2 , 5 The touch cutting mechanism 3 includes a cutting frame 31, a reset electric cylinder 32, a cutting motor 33, a cutting blade 34, a touch plate 35, a reset spring 36, a battery 37, a compression spring 38 and a mounting plate 39; the cutting frame 31 is installed on the ground where the lateral pushing mechanism 4 is away from the lifting support mechanism 2, and a processing table 311 is arranged on the cutting frame 31, and a steel bar cutting cavity 3111 is horizontally opened on the processing table 311, and one end of the steel bar cutting cavity 3111 is opened directly opposite to the end of the main steel bar; the reset electric cylinder 32 is installed on the cutting The top of the cutting frame 31, and the piston rod of the reset electric cylinder 32 extends vertically downward, the mounting plate 39 is installed on the end of the piston rod of the reset electric cylinder 32, the cutting motor 33 is arranged on the mounting plate 39, the cutting blade 34 is installed on the output shaft of the cutting motor 33, and the cutting blade 34 is located above the end opening of the steel bar cutting chamber 3111; the compression spring 38 is installed on the cutting frame 31, and the lower end of the compression spring 38 is connected to the upper plate surface of the mounting plate 39, and the compression spring 38 always has a tendency to pull the mounting plate 39 vertically upward; combined with Figure 6A receiving groove 312 is provided on the end wall of the cutting frame 31 away from the lateral pushing mechanism 4. One end of the return spring 36 is connected to the inner end wall of the receiving groove 312, and the other end is connected to a touch plate 35. The touch plate 35 is placed in the steel bar cutting cavity 3111 and directly faces the receiving groove 312. The battery 37 is installed in the cutting frame 31 on one side of the receiving groove 312. A conductive plate 351 is provided on the plate surface of the touch plate 35 directly facing the receiving groove 312. The conductive plate 351 and the battery The battery 37 is electrically connected; a power transmission plate 3121 is provided on the inner wall of the storage groove 312, and the power transmission plate 3121 is electrically connected to the reset electric cylinder 32 and the cutting motor 33; when the main steel bar is pushed into the steel bar cutting cavity 3111 and the conductive plate 351 on the touch plate 35 is pushed to fit with the power transmission plate 3121 on the storage groove 312, the horizontal straight line distance between the cutting blade 34 and the touch plate 35 away from the plate surface of the conductive plate 351 is the preset length of the main steel bar.

[0066] When the main steel bar is clamped and gradually moves into the steel bar cutting cavity 3111, the touch plate 35 in the steel bar cutting cavity 3111 will be pushed by the main steel bar to continue to move towards the storage groove 312; and after pushing the touch plate 35 to move into the storage groove 312, the conductive plate 351 will first contact the power transmission plate 3121, and then the power on the battery 37 will be transmitted to the reset electric cylinder 32, thereby driving the piston rod of the reset electric cylinder 32 to extend; it will also transmit electricity to the cutting motor 33 on the mounting plate 39, so that the cutting motor 33 will operate, and after the cutting motor 33 operates The cutting blade 34 is driven to rotate. At this time, the rotating cutting blade 34 will move downward under the drive of the resetting electric cylinder 32, and then gradually cut off the main steel bar. After this setting, it is only necessary to push the main steel bar into the steel bar cutting cavity 3111 to realize automatic cutting of the main steel bar, and because the horizontal straight line distance between the cutting blade 34 and the touch plate 35 away from the conductive plate 351 is the preset length of the main steel bar, the length of the cut main steel bar is directly the standard length, which improves the degree of automation during the entire main steel bar cutting and greatly reduces the labor intensity of workers.

[0067] In conjunction with Figures 5 and 7, the automatic collection mechanism 5 includes a collection box 51, which is installed on one side of the processing table 311. The processing table 311 is provided with a collection channel 3112 which is inclined. The lowest inclined end of the collection channel 3112 is connected to the collection box 51, and the highest inclined end is connected to the steel bar cutting cavity 3111. The processing table 311 is provided with a receiving groove 3113 at the boundary between the steel bar cutting cavity 3111 and the collection channel 3112. A telescopic spring 3114 is arranged in the receiving groove 3113. The telescopic spring A dividing plate is provided at the top of 3114; when the telescopic spring 3114 is in a natural state, the dividing plate extends from the accommodating groove 3113 and separates the steel bar cutting cavity 3111 from the collecting channel 3112; an L-shaped extrusion rod 391 is vertically provided on the mounting plate 39, and one side of the dividing plate extends from the accommodating groove 3113 and is located directly below the L-shaped extrusion rod 391; after the cutting blade 34 completely cuts off the main steel bar, the L-shaped extrusion rod 391 pushes the dividing plate back into the accommodating groove 3113 in the vertical direction. It is worth noting that in the present embodiment, the collecting channel 3112 is opened at one end close to the clamping assembly 7, and the preset length of the main steel bar is longer than the length of the steel bar cutting cavity 3111 and also longer than the length of the collecting channel 3112, that is, the main steel bar after cutting will extend one end when rolling in the collecting channel 3112; and the collecting box 51 is also opened on one side close to the clamping assembly 7, that is, after the stacked main steel bars enter the collecting box 51, one end of them will extend out of the collecting box 51.

[0068] When the mounting plate 39 is pushed by the reset electric cylinder 32 to move vertically downward, the L-shaped extrusion rod 391 on the mounting plate 39 will also move vertically downward, thereby pressing against the dividing plate to move vertically downward; at this time, the portion of the dividing plate extending out of the receiving groove 3113 will be pressed to move into the receiving groove 3113 until it is completely below the upper end opening of the receiving groove 3113 in the height direction; at this time, there is no obstruction between the steel bar cutting cavity 3111 and the collecting channel 3112, and under the action of gravity, the cut main steel bars in the steel bar cutting cavity 3111 will roll along the collecting channel 3112 into the collecting box 51 Storage; the main steel bar no longer resists the touch plate 35, and under the elastic force of the reset spring 36, the conductive plate 351 is separated from the power transmission plate 3121, and the battery 37 no longer supplies electricity to the cutting motor 33 and the reset cylinder 32. The piston rod of the reset cylinder loses power, and at this time the compression spring 38 will move vertically upward with the mounting plate 39 again under the action of its own compression elastic force, and all equipment is restored to the state before the main steel bar enters the steel bar cutting chamber 3111, so as to cut the next main steel bar, so as to achieve the effect of automatically resetting after cutting one main steel bar and preparing to cut the next main steel bar.

[0069] The implementation principle of the main steel bar cutting step in the embodiment of the present application is:

[0070] First, place the main steel bar to be cut on the multiple rolling shafts 23, then start the lifting cylinder 21 to lift the main steel bar to the same height as the steel bar cutting cavity 3111, then manually push the main steel bar to allow the main steel bar to enter between the two extrusion blocks 73, and then drive the piston rod of the stripping cylinder 82 to contract, so that the two extrusion blocks 73 are close to each other, so that the rubber lining 74 abuts against both sides of the main steel bar; then start the telescopic cylinder 91, so that the telescopic cylinder 91 brings the moving plate 71 close to the steel bar cutting cavity Then, the stripping cylinder 82 is started again to allow the stripping block 83 to push the two extrusion blocks 73 apart again, so that the rubber lining 74 is no longer close to the main steel bar, and then the telescopic cylinder 91 is started to allow the movable plate 71 to return to the initial position; the above steps are repeated to allow the main steel bar to continuously enter the steel bar cutting cavity 3111, and finally the end of the main steel bar pushes the touch plate 35 to move, so that the touch plate 35 enters the storage groove 312, and the conductive plate 351 is fitted with the power transmission plate 3121, and the electricity is stored. The battery 37 transmits power to the cutting motor 33 and the reset electric cylinder 32; at this time, the cutting blade 34 operates, the reset electric cylinder 32 drives the mounting plate 39 to move downward, the compression spring 38 stretches, the cutting blade 34 contacts the main steel bar and cuts the main steel bar; as the mounting plate 39 continues to move downward, the L-shaped extrusion rod 391 will press the dividing plate to move vertically downward, so that the dividing plate no longer blocks the connection between the steel bar cutting cavity 3111 and the collecting channel 3112; under the action of gravity, the cut main steel bar will enter the collecting channel 3112 The touch plate 35 is inserted into the collecting box 51, and the cutting work of one main steel bar is completed. The main steel bar will not exert a thrust on the touch plate 35 at this time. The reset spring 36 brings the touch plate 35 from the storage groove 312 back to the steel bar cutting chamber 3111. The battery 37, the reset electric cylinder 32 and the cutting motor 33 are all powered off, and the piston rod of the reset electric cylinder 32 loses power. At this time, the compression spring 38 contracts, and the mounting plate 39 is lifted vertically upward. The cutting blade 34 is also above the main steel bar again, waiting for the next cutting.
