Usually, when installing large columns, it is necessary to align the mounting holes at the bottom of the columns with the embedded screws on the ground. This is a delicate process and the accuracy of the installation position must be ensured. The current operation method mainly relies on the crane to lift the large column to the vicinity of the embedded screws, and then multiple workers push the column horizontally at the bottom of the column to fine-tune the column so that the mounting holes at the bottom of the column are aligned with the embedded screws.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The present application embodiment discloses a large column 1 installation and positioning device, which is used for Figure 1 The installation and positioning process of the large column 1 is shown. Figure 2 and Figure 3 The large column 1 installation and positioning device includes a mobile platform 4 and a walking device 5, a positioning device, a camera device 7 and a control console 9 arranged on the mobile platform 4. The mobile platform 4 is a rectangular platform. A construction groove 41 for the column 1 to pass through is opened on the mobile platform 4. The opening of the construction groove 41 is opened toward the tail of the mobile platform 4, so that the mobile platform 4 forms a U shape as a whole, which is convenient for the column 1 to be separated from the mobile platform 4 after the installation of the column 1 is completed; the end of the construction groove 41 away from the opening forms a positioning area 42, and the column 1 is positioned in the positioning area 42; the walking device 5 is located on the mobile platform The bottom of the platform 4 is used to move or lock the mobile platform 4; the positioning device includes a plurality of positioning components 6 arranged in a ring in the positioning area 42, which are used to position the circumference of the column 1; the camera device 7 is used to monitor the positions of the mobile platform 4 and the embedded screw 3 to navigate and position the mobile platform 4; the control console 9 controls the movement of the mobile platform 4 according to the camera device 7, so that the center of the positioning area 42 is aligned with the center of the line connecting the embedded screw 3 in the horizontal direction, and controls the positioning device to position the column 1 according to the geometric data of the column 1, so that the mounting hole 11 on the column 1 is aligned with the embedded screw 3.

[0026] When installing a large column 1, the camera device 7 assists in monitoring, and the walking device 5 drives the mobile platform 4 to move to the location of the embedded screw 3, so that the embedded screw 3 is located in the positioning area 42, and the column 1 is suspended in the positioning area 42. The control console 9 controls the positioning device to position the column 1 according to the geometric size data of the column 1, so that the column 1 and the embedded screw 3 are accurately docked. By assisting the positioning of the column 1 with the control console 9, the accuracy of the positioning of the column 1 can be greatly improved, and the positioning efficiency can be greatly improved, and the possibility of rework caused by the column 1 bending the embedded screw 3 due to positioning deviation can be reduced, thereby greatly improving the convenience of installing the column 1.

[0027] For details, please refer to Figure 4 The positioning assembly 6 includes a mounting plate 61, a movable plate 62, a driving assembly and a plurality of guide wheels 63. The mounting plate 61 and the mounting plate 61 are both rectangular plates and are both arranged vertically. The mounting plate 61 is arranged on the mobile platform 4, and the movable plate 62 is arranged to slide horizontally on the side of the mounting plate 61 close to the positioning area 42. The guide wheels 63 are arranged on the side of the movable plate 62 close to the positioning area 42, and the plurality of guide wheels 63 are arranged on the movable plate 62 at equal intervals in a vertical direction. The driving assembly is arranged on the mounting plate 61 to drive the movable plate 62 to slide.

[0028] When positioning the column 1, the driving assembly drives the movable plate 62 to slide, so that the movable plate 62 drives the guide wheel 63 to abut against the side of the column 1. The rotation of the guide wheel 63 allows the column 1 to move freely in the vertical direction, reducing the possibility of wear of the positioning assembly 6 on the column 1. The guide wheels 63 of multiple groups of positioning assemblies 6 are used to position the peripheral sides of the column 1 respectively, thereby achieving accurate and non-destructive positioning of the column 1.

[0029] The driving assembly includes a driving threaded barrel 65, a driving screw 64, a guide rod 66 and a driving member. The driving threaded barrel 65 is rotatably connected to the mounting plate 61 through a bearing. Two guide rods 66 are provided in parallel. One end of the guide rod 66 is welded and fixed to the movable plate 62, and the other end passes through and is axially slidably arranged on the mounting plate 61 along the guide rod 66. The driving screw 64 is arranged in parallel with the guide rod 66. The driving screw 64 is threadedly connected to the driving threaded barrel 65. One end of the driving screw 64 passes through the mounting plate 61 and is welded and fixed to the movable plate 62. The driving member includes a driving motor 67 and a reduction gear set 68. The driving motor 67 adopts a servo motor. The input gear and the output gear of the reduction gear set 68 are coaxially fixedly connected to the output shaft of the driving motor 67 and the driving threaded barrel 65, respectively. Through the driving mode of the driving motor 67 in conjunction with the reduction gear and the driving screw 64, the accuracy of the movement of the movable plate 62 can be greatly improved, thereby improving the accuracy of the positioning of the column 1.

[0030] Since the column 1 as a whole usually has four sides, in order to facilitate the positioning of the four sides of the column 1, the positioning area 42 is set to be a square, and the corresponding positioning components 6 are provided with four groups, and the four groups of positioning components 6 are respectively located on the four sides of the positioning area 42. When in the starting position, the guide wheels 63 of the four positioning components 6 are tangent to the four sides of the positioning area 42 respectively. Figure 5 As shown, the dotted line portion is the edge line of the positioning area 42.

[0031] In order to facilitate the installed column 1 to be able to detach from the mobile platform 4, the positioning component 6 close to the opening direction of the construction groove 41 needs to avoid the column 1. Specifically, this group of positioning components 6 is movably set on the mobile platform 4 between the expanded state and the avoided state through the avoidance device 8. When in the expanded state, the positioning component 6 is located within the scope of the construction groove 41. When in the avoided state, the positioning component 6 is located outside the scope of the construction groove 41.

[0032] For details, please refer to Figure 7The avoidance device 8 includes an avoidance bracket 81, an avoidance slide 82 and an avoidance drive 83. The avoidance bracket 81 is fixed to the mobile platform 4 by bolts and is located on one side of the construction groove 41. The avoidance slide 82 is a U-shaped plate. The mounting plate 61 of the positioning assembly 6 close to the opening of the construction groove 41 is embedded in the avoidance slide 82 and is fixedly connected to the avoidance slide 82 by bolts. The avoidance drive 83 includes but is not limited to a cylinder, a hydraulic cylinder or an electric push rod. The avoidance drive 83 is fixedly connected to the avoidance bracket 81 by bolts, and the side of the sliding seat away from the mounting plate 61 is fixedly connected to the movable end of the avoidance drive 83.

[0033] In order to improve the stability of the avoidance slide 82 when it slides, the avoidance bracket 81 is provided with avoidance guide rods 84 on the upper and lower sides of the avoidance drive 83. One end of the avoidance guide rod 84 is welded and fixed to the avoidance slide 82, and the other end passes through the avoidance bracket 81 and is slidably connected to the avoidance bracket 81 along the sliding direction of the avoidance slide 82. By adding two avoidance guide rods 84 to limit the avoidance slide 82, the stability of the avoidance slide 82 when it slides can be improved, and the stability of the positioning assembly 6 in the deployed state can be improved.

[0034] After the column 1 is positioned and installed, the avoidance drive 83 controls the avoidance slide 82 to move close to the avoidance bracket 81, so that the positioning assembly 6 installed on the avoidance slide 82 leaves the range of the construction groove 41, so that the column 1 can be avoided, and when the mobile platform 4 moves along the length direction of the construction groove 41, the column 1 can be unobstructed from the opening of the construction groove 41. Disconnected from the mobile platform 4. When the column 1 is completely separated from the mobile platform 4, the avoidance drive 83 controls the slide to move away from the avoidance bracket 81, so that the positioning assembly 6 installed on the avoidance slide 82 enters the deployment state, thereby preparing for the next positioning of the column 1.

[0035] The camera device 7 includes a guide camera 71 and a positioning camera 72. Figure 3 As shown, the guide camera 71 is located at the head of the mobile platform 4 and is used to monitor the surrounding environment of the mobile platform 4, and guide the mobile platform 4 to find the target embedded screw 3 position for guidance. The guide camera 71 can be a wide-angle industrial camera. The positioning camera 72 is located on the side of the construction groove 41 away from the avoidance device 8, and is used to monitor the position of the embedded screw 3 within the construction groove 41. Since the positioning camera 72 needs to locate the position of the embedded screw 3 with high precision, the positioning camera 72 can use a high-resolution industrial camera to accurately capture the position of the embedded screw 3.

[0036] When the camera device 7 guides the mobile platform 4, the guiding camera 71 monitors the environment around the mobile platform 4, so that the mobile platform 4 can quickly find the position of the embedded screw 3, and make the embedded screw 3 enter the positioning area 42 of the mobile platform 4. The positioning camera 72 accurately positions the embedded screw 3 in the positioning area 42, and controls the center of the positioning area 42 of the mobile platform 4 to align with the center of the connection line of multiple embedded screws 3, thereby completing the accurate positioning of the mobile platform 4 and laying the foundation for the accurate positioning of the column 1.

[0037] The walking device 5 includes a plurality of walking wheels 51 and a walking drive for driving the walking wheels 51 to rotate. There are four walking wheels 51, which are respectively located at the four corners of the mobile platform 4. The walking drive is a wheel drive structure compared with the existing ones, which will not be further expanded here. The walking drive drives the walking wheels 51 to rotate and turn, and cooperates with the guidance of the camera device 7 to control the precise positioning of the mobile platform 4. In order to improve the flexibility of the mobile platform 4, the walking wheels 51 are arranged at the bottom of the mobile platform 4 in a lifting manner. The lifting of the walking wheels 51 can be driven by hydraulic cylinders, electric push rods or motor screws, so that the mobile platform 4 can be raised or lowered as needed, so that the mobile platform 4 can cross obstacles of different heights, greatly improving the flexibility of the mobile platform 4.

[0038] In order to facilitate the fixing of the mobile platform 4, a plurality of support columns 52 are provided at the bottom of the mobile platform 4. In this embodiment, four support columns 52 are provided, which are respectively located at the four corners of the mobile platform 4 and are staggered with the running wheels 51. When the mobile platform 4 needs to be fixed, the running wheels 51 are driven to rise above the ground of the support columns 52 so that the support columns 52 abut against the ground, and the mobile platform 4 can be fixed. When the mobile platform 4 needs to be driven to move again, the running wheels 51 are lowered so that the running wheels 51 prop up the mobile platform 4 and the support columns 52 are off the ground, and the mobile platform 4 can be driven to move freely.

[0039] Taking into account the possible unevenness of the construction environment, the four support columns 52 are arranged to be raise and lowered, and a spirit level is arranged on the top surface of the mobile platform 4. By driving the support columns 52 to rise and fall and making the spirit level data meet the horizontal standard, the mobile platform 4 can be horizontally fixed, thereby reducing the possibility of inaccurate positioning of the column 1 due to the tilt of the mobile platform 4.

[0040] The present application also discloses a method for using a large column 1 installation positioning device, which specifically includes the following steps: S1, inputting the position data and cross-sectional information data of the mounting hole 11 of the steel column 1 into the control console 9, the control console 9 calculates the center position points of the plurality of mounting holes 11, records them as theoretical positioning points, and determines the distances A1, A2, A3, and A4 of the four sides of the column 1 from the theoretical positioning points according to the cross-sectional information of the column 1; S2, the walking device 5 cooperates with the camera device 7 to control the mobile platform 4 to move to the embedded screw 3, and determines the center point of multiple embedded screws 3, which is recorded as the actual positioning point. The control console 9 controls the mobile platform 4 to move so that the center of the positioning area 42 coincides with the actual positioning point, and the lifting wheel rises to support the fixed legs on the ground, so that the mobile platform 4 is fixed, so that the center of the positioning area 42 of the mobile platform 4 is aligned with the actual positioning point, and the positioning of the mobile platform 4 is completed; S3, the control console 9 calculates the positioning amount of each group of positioning components 6. Specifically, when the guide wheels 63 of the four groups of positioning components 6 are in the initial position, the distance from the center of the positioning area 42 is B. The control console 9 calculates that the distance that each group of guide wheels 63 needs to move is (B-A1), (B-A2), (B-A3), (B-A4), which is the positioning amount of each group of positioning components 6; S4, suspend the column 1 to the positioning area 42 of the mobile platform 4 by the crane 2, and control the movement of each group of positioning components 6 according to the positioning amount in S3, so that each group of positioning components 6 positions the column 1, so that the theoretical positioning point and the actual positioning point are kept consistent in horizontal direction, thereby realizing the positioning of the column 1; S5, control the crane 2 to lower the column 1, so that the column 1 descends along the guide wheel 63 until the installation hole 11 of the column 1 is docked with the embedded screw 3, and the column 1 is locked by the nut to complete the installation of the column 1; S6. The avoidance device 8 controls the corresponding positioning assembly 6 to enter the avoidance state, controls the movement of the mobile platform 4, and enables the column 1 to detach from the mobile platform 4 through the opening of the construction groove 41.
