Description

Technical Field

[0001] This invention belongs to the field of steel cage processing equipment, and more specifically, it relates to an integrated machine for fabricating and installing vertical steel cages for pile foundations. Background Technology

[0002] As a fundamental facility for the construction of iron towers, deep foundation pits directly affect the overall construction quality of the towers. The steel cage, as the skeleton of the deep foundation pit, is also of paramount importance in terms of its finished product quality, which has a profound impact on the service life of the iron towers.

[0003] Currently, most of the steel cages used on construction sites are prefabricated products manufactured in workshops and transported to the site, or they are welded or tied on-site (e.g., Figures 5 to 6 As shown in the figure, the on-site construction environment is harsh and resources are scarce. The welding skills of the personnel vary, which makes it impossible to guarantee the quality of the welded steel cages. There may be cases of missing welds or incomplete welds. When binding, due to the lack of special equipment, the spacing, diameter deviation, and verticality deviation of the main bars of the steel cage made by visual inspection and experience are significantly different from the standards and may fail the inspection.

[0004] The steel cage fabrication equipment in workshops generally has a main bar fixing system and an automatic feeding system, which can significantly reduce errors in spacing and verticality, and is self-powered, slightly reducing the workload of operators. However, there is still a lot of manual welding work, and the steel cage is huge after it is fabricated, making transportation very difficult. Summary of the Invention

[0005] To address the above deficiencies, this invention provides an integrated machine for fabricating and installing vertical steel cages for pile foundations, comprising a main frame and a steel cage. The main frame is slidably equipped with cage translation mechanisms on all four sides for adjusting the four-way position of the steel cage. The main reinforcement bars are fixed by a main reinforcement bar feeding device and conveyed downward to a winding and welding device for winding and welding of the outer stirrups. The invention also includes a control cabinet for controlling various electrical components.

[0006] Furthermore, the cage translation mechanism includes a wheel frame, each of which is slidably connected to the guide rails set on the four sides of the main frame through two internally rotatably connected movable wheels. A stepper motor is also installed on the outer side of the wheel frame, and the output end of the stepper motor drives the two movable wheels to rotate through a linkage, thereby causing the wheel frame to slide on the guide rail. A telescopic arm connected to the steel cage is installed at the bottom end of the wheel frame.

[0007] Furthermore, the telescopic arm is connected to the bottom end of the steel cage via a fixed connecting plate.

[0008] Furthermore, the main reinforcement feeding device includes a reinforcing cage connecting plate connected to four connecting plates. A main frame is installed on the reinforcing cage connecting plate. A screw motor is installed on the main frame. The output end of the screw motor is connected to a power wheel frame. A power wheel is installed on the power wheel frame. A telescopic electric cylinder is also installed on the main frame. An auxiliary wheel frame that is slidably connected to the main frame is installed at the output end of the telescopic electric cylinder. An auxiliary wheel that cooperates with the power wheel is installed at the auxiliary wheel frame.

[0009] Furthermore, the steel cage frame includes an upper ring and a lower ring, which are fixed together by a number of columns arranged in a ring array. The top of the upper ring is fixed with an auxiliary positioning ring sleeved on the outside of the steel cage by a number of diagonal braces arranged in a ring array. Positioning clips adapted to each steel bar are installed at equal intervals on the upper surface of the auxiliary positioning ring.

[0010] Furthermore, the winding welding device includes a gear ring fixed to the inner ring of the lower ring. The top of the gear ring is provided with two movable base plates. The top of the movable base plate on the left is fixed with an outer hoop rope disc for rotating and winding the outer hoop, as well as a wire correction device for correcting and guiding the outer hoop. The top of the movable base plate on the right is fixed with a multi-directional robotic arm and an electrical control box. A vision recognition camera is installed at the bottom of the multi-directional robotic arm, and a welding torch is installed at the end. The electrical control box is used to control the welding torch to perform welding based on the information of the overlapping parts of the reinforcing bars identified by the vision recognition camera.

[0011] Both of the movable base plates are equipped with a geared motor. The output end of the geared motor passes through the inner wall of the movable base plate and is fixed with a gear. The gear meshes with the gear ring to realize the movement of the movable base plate.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The traditional steel cage fabrication equipment is miniaturized by setting up a main frame, which allows the equipment to automatically move to the next nearby work point after completing one operation, eliminating the need for overall relocation. This solves the problems of difficult steel cage transportation and inability to guarantee on-site fabrication quality, and frees up manpower.

[0014] The automatic welding function adopts a visual recognition scheme, which can accurately identify the welding points. Equipped with an eight-way robotic arm welding gun, it greatly reduces the possibility of missed welding. The rebar cage adopts an integrated fabrication and lowering scheme. The whole machine is controlled by a PLC industrial control system. All actions are driven by motors, which can achieve precise control of the entire mechanism's movements. This realizes fully automated rebar cage fabrication, improves work efficiency during construction, and is widely applicable to various deep foundation pit conditions. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example

[0024] like Figure 1 As shown, this embodiment provides an integrated machine for fabricating and installing vertical steel cages for pile foundations, including a main frame 1 and a steel cage 2 (it should be noted that...). Figure 1The steel cage 2 in the middle is in a state without external stirrups and consists of several main bars. The main bars are only tied at the bottom so that they can form a whole, which facilitates subsequent movement. For ease of description, we will use steel cage 2. The four sides of the main frame 1 are slidably installed with cage frame translation mechanism 3 for adjusting the four-way position of the steel cage frame 5. The main bars are fixed by the main bar feeding device 4 and conveyed downward to the winding and welding device 6 for the winding and welding of external stirrups. There is also a control cabinet 7 for controlling various electrical components. The specific structure is as follows:

[0025] like Figure 2 As shown, the cage translation mechanism 3 includes a wheel frame 31. Each wheel frame 31 is slidably connected to the guide rails 11 set on the four sides of the main frame 1 through two internally rotatably connected movable wheels 32. A stepper motor 33 is also installed on the outside of the wheel frame 31. The output end of the stepper motor 33 drives the two movable wheels 32 to rotate through the linkage, causing the wheel frame 31 to slide on the guide rail 11. A telescopic arm 34 (i.e., composed of nested wall bodies, which can be referred to as the telescopic structure of a crane, and will not be described in detail here) is installed at the bottom of the wheel frame 31. The telescopic arm 34 is connected to the bottom of the steel cage 5 through a fixed connecting plate 35, thereby realizing the four-way translation function of the steel cage 5.

[0026] It should be noted that the linkage can be a synchronous gear system (connected by one or more sets of gears to ensure that the two wheels rotate synchronously), a belt synchronization system, or other structures, or it can be used with existing electric hoist trolleys. All of these are existing technologies and will not be elaborated here.

[0027] like Figure 3As shown, the main reinforcement feeding device 4 includes a reinforcing cage connecting plate 41 connected to four connecting plates 35. The outer ring of the reinforcing cage connecting plate 41 has an external protrusion for bolt fixing of the four connecting plates 35, facilitating installation and disassembly. A main frame 42 is mounted on the reinforcing cage connecting plate 41, and a screw motor 43 is mounted on the main frame 42. The output end of the screw motor 43 is connected to a power wheel frame 44, which can drive the power wheel frame 44 to perform axial movement through the rotation of the screw motor 43. A power wheel 45 is mounted on the power wheel frame 44. A telescopic electric cylinder 46 is also mounted on the main frame 42, and the output end of the telescopic electric cylinder 46 is equipped with a sliding connection to the main frame 42. The auxiliary wheel frame 47 is connected (through the traditional sliding connection between the slider and the slide rail, i.e., the main frame 42 is equipped with a slide rail, and the bottom of the auxiliary wheel frame 47 is equipped with a slider, and the two slide together). The telescopic electric cylinder 46 can drive the auxiliary wheel frame 47 to move laterally by rotating. The auxiliary wheel frame 47 is equipped with an auxiliary wheel 48 that cooperates with the power wheel 45. Through the axial movement of the power wheel frame 44 and the lateral movement of the auxiliary wheel frame 47, the power wheel 45 and the auxiliary wheel 48 can cooperate to clamp the adjacent main bars, thereby realizing the function of adjusting the spacing of the main bars (i.e., the spacing of the steel cage 2). The power wheel 45 and the auxiliary wheel 48 are both provided with wheel grooves for the main bars to be inserted.

[0028] In detail, the steel cage frame 5 includes an upper ring 51 and a lower ring 52. The upper ring 51 and the lower ring 52 are fixed together by a number of columns 56 arranged in a ring. The top of the upper ring 51 is fixed with an auxiliary positioning ring 54 sleeved on the outside of the steel cage 2 by a number of diagonal braces 53 arranged in a ring, so as to achieve good stability. The upper surface of the auxiliary positioning ring 54 is equidistantly installed with positioning clips 55 that are adapted to each steel bar. The positioning clips 55 can be directly welded or fixed by bolts. The positioning clips 55 are used for positioning holes for the main reinforcement to pass through, and cooperate with the main reinforcement feeding device 4 to realize the positioning work of the steel cage 2.

[0029] like Figure 4As shown, the winding welding device 6 includes a gear ring 61 fixed to the inner ring of the lower ring 52. Two movable base plates 62 are provided on the top of the gear ring 61. The top of the movable base plate 62 on the left side is fixed with an outer hoop rope disc 63 for rotating and winding the outer hoop, and a lead-out correction device 64 for correcting and guiding the outer hoop. The outer hoop rope disc 63 is cylindrical, consisting of a cylinder and a base plate, which are rotatably connected by a rotating shaft. The base plate is fixed to the movable base plate 62 on the left side, allowing the cylinder to rotate on its own, facilitating the subsequent winding of the outer hoop. When the outer stirrups are conveyed, they will pass through the outgoing line correction device 64 for correction. It should be noted that the outgoing line correction device 64 is equipped with a roller group inside, which can correct and guide the outer stirrups (i.e., the structure of a traditional steel bar straightener). The top of the movable base plate 62 on the right side is fixed with a multi-directional robotic arm 65 and an electrical control box 66. A vision recognition camera 68 is installed at the bottom of the multi-directional robotic arm 65, and a welding torch 67 is installed at the end. The electrical control box 66 is used to control the welding torch 67 to perform welding based on the information of the overlapping parts of the steel bars identified by the vision recognition camera 68.

[0030] It should be noted that both movable base plates 62 are equipped with geared motors 69. The output end of the geared motor 69 passes through the inner wall of the movable base plate 62 and is fixed with a gear. The gear meshes with the gear ring 61 to realize the movement of the movable base plate 62.

[0031] The embodiment of the vertical steel cage fabrication and installation machine for pile foundation described herein has a cage frame translation mechanism 3 that can slide freely on the main frame 1 via guide rail 11 and is fixed at its end to the steel cage frame 5. Through cooperation, the steel cage frame 5 can be translated in four directions, allowing the steel cage 2 to pass through the main reinforcement feeding device 4 and the auxiliary positioning ring 54 below and be fixed and clamped by each positioning clamp 55. Since the main reinforcement feeding device 4 has its own power (i.e. driven by the power wheel 45), after the power wheel 45 and the auxiliary wheel 48 are clamped, the main reinforcement feeding device 4 can control the overall up and down movement of the steel cage 2. During the downward movement, the winding and welding device 6 automatically performs the winding and welding of the outer stirrups until the fabrication of the steel cage 2 is completed and the steel cage 2 is completely placed in the deep foundation pit. Then, it moves to the next work point to repeat the work.

[0032] It should be noted that the above work process can be automated through a PLC industrial control system, and will not be elaborated here.

[0033] It should be noted that the structure described in this invention can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the description and drawings of this invention, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this invention.
