Description

TECHNICAL FIELD

[0001] The present application relates to a large-scale radial gate hinge shaft installation device and construction method, belonging to the technical field of production and operation. BACKGROUND

[0002] The radial gate is one of the most commonly used gate types in modern water conservancy and hydropower projects. The hinge shaft is a core load-bearing rotating component that is installed on the hinge seat of the gate pier. The shaft is used to connect the gate arm, transfer water pressure and the weight of the gate body, and provide a rotating center for the opening and closing operation of the gate.

[0003] Currently, the main method for removing and installing the radial gate hinge shaft is to use a jack to lift the hinge shaft out and impact it into the hinge bearing. The impact can cause uneven stress on the hinge shaft, resulting in jamming during installation. Moreover, cranes are often used to install the hinge shaft, resulting in low installation position accuracy.

[0004] The removal and installation of the radial gate hinge shaft generally use the construction method of lifting out with a jack and impacting into. During the installation stage, the shaft is forcibly installed into the bearing by external impact. This method can cause the hinge shaft to bear uneven impact loads during installation, resulting in shaft body deflection and jamming, affecting installation quality. In addition, positioning and assembly of the shaft often rely on cranes in common construction, which lacks stability during lifting and positioning accuracy is difficult to guarantee. The final installation position of the hinge shaft may deviate, affecting the reliability and service life of the overall gate operation. SUMMARY

[0005] The present application aims to provide a large-scale radial gate hinge shaft installation device and construction method to solve the problems raised in the background.

[0006] The technical solution of the present application is as follows: A large-scale radial gate hinge shaft installation device, characterized by: a hinge device, and a measuring device installed on one side of the hinge device, the measuring device and the shaft hole of the hinge device are concentric, and the measuring device is uniformly provided with a plurality of distance measuring sensors along its axial direction; Further comprising a Z-axis moving assembly and an X-axis moving assembly arranged on the Z-axis moving assembly, the X-axis moving assembly is provided with a Y-axis moving assembly, a jack and a plurality of adjustment assemblies arranged along the moving direction of the Y-axis moving assembly; the moving direction of the jack and the Y-axis moving assembly is consistent; Each adjustment assembly comprises a U-shaped groove provided with a circular arc groove at the top, two groups of clamping pieces are arranged side by side on the circular arc groove along the moving direction of the Y-axis moving assembly, and a corresponding set of expansion pieces is arranged on the position corresponding to the two groups of clamping pieces on the side wall and the lower surface of the U-shaped frame, respectively. A first distance measuring sensor is arranged on the adjustment assembly close to the jack.

[0007] Furthermore, a base is provided below the Z-axis moving component, and rollers are provided at the four corners of the lower surface of the base.

[0008] Furthermore, the Z-axis moving component includes two support rods, each with a lifting rod inside and a lifting plate mounted on the lifting rod. A support plate is installed between the two support rods via the lifting plate, and the support plate is used to support the X-axis moving component.

[0009] Furthermore, a support frame is installed on the X-axis moving component, and a Y-axis moving component is set on the top of the support frame. The jack is connected to one side of the Y-axis moving component through an L-shaped bracket.

[0010] Furthermore, the two clamping groups are a first clamping group and a second clamping group, respectively. The first clamping group includes three first clamping members arranged side by side along the moving direction of the X-axis moving group, and the second clamping group includes three second clamping members arranged side by side along the moving direction of the X-axis moving group. Each second clamping member is provided with a ball bearing. The two sets of telescopic components are the first telescopic component group and the second telescopic component group. The first telescopic component group includes three first telescopic components, which correspond one-to-one with the first clamping components. The second telescopic component group includes three second telescopic components, which correspond one-to-one with the second clamping components.

[0011] Furthermore, the annular measuring component has four mounting positions evenly distributed on its circumference, and each mounting position is equipped with two parallel distance sensors. The distance sensors are used to measure the vertical and horizontal offset of the hinge axis. When measuring the vertical offset, two distance sensors located directly opposite each other on the ring form a group, forming a total of four groups of distance sensors. When measuring horizontal offset, two side sensors arranged side by side at the same mounting position form a group, forming a total of four groups of distance measuring sensors.

[0012] A construction method for a large arc-shaped gate hinge shaft installation device, using the aforementioned large arc-shaped gate hinge shaft installation device, includes the following specific steps: S1: The measuring device is installed on one side of the hinge device, and the measuring device and the shaft hole of the hinge device are kept concentric. S2: Place the hinge shaft in the adjustment assembly, adjust the telescopic assembly so that the first clamping assembly abuts against the hinge shaft and the second clamping assembly does not abut against the hinge shaft. The Z-axis moving assembly drives the support plate to move vertically, and the X-axis moving assembly drives the support frame to move horizontally, so that the hinge shaft is aligned with the position to be installed. S3: The jack is driven by the Y-axis moving component. During the process of the jack pushing the hinge shaft into the hinge device, the measuring device feeds back the vertical and horizontal offset of the hinge shaft. The first distance sensor feeds back the distance between the first distance sensor and the end face of the hinge shaft. Based on the feedback measurement data, the position of the hinge shaft is adjusted by the Z-axis moving component, the X-axis moving component and the adjustment component.

[0013] The present invention has the following beneficial effects: The measuring device and the hinge device are set to be coaxial, the output shaft of the jack is coaxial with the hinge shaft, and the jack acts directly on the center point of the hinge shaft, so that the hinge shaft is evenly stressed. By setting up X-axis, Y-axis, and Z-axis movement components, a wide range of adjustment of the hinge shaft position can be achieved. Small-range adjustments of the hinge shaft can be made using adjustment components, thereby improving the installation accuracy of the hinge shaft. A measuring device is set up to measure the vertical and horizontal offsets. These measurements are then combined with the X-axis, Y-axis, Z-axis, and adjustment components for further adjustments, thereby improving the installation accuracy of the hinge shaft. The clamping and telescopic components work together to ensure that the jack is not limited by different diameter sections of the hinge shaft when pushing the hinge shaft, thus avoiding wear on the hinge shaft, adapting to hinge shafts of various sizes, and improving the applicability of the installation device.

The Y-axis moving assembly is used to drive the jack 14 to push the hinge shaft 16 to move towards the hinge device 1.

[0021] Adjustment assembly 8 is used to place hinge shaft 16. Multiple sets of adjustment assemblies 8 are arranged side by side on the bottom upper surface of support frame 7 along the moving direction of Y-axis moving assembly 4. In this embodiment, adjustment assembly 8 includes adjustment assembly one 801, adjustment assembly two 802 and adjustment assembly three 803. The three sets of adjustment assemblies 8 are set to jointly support hinge shaft 16 to avoid the center of gravity of hinge shaft 16 shifting and improve assembly accuracy. Adjustment assembly one 801 is provided with a first distance sensor 806.

[0022] Example 2: A construction method for a large arc-shaped gate hinge shaft installation device, using the aforementioned large arc-shaped gate hinge shaft installation device, includes the following specific steps: S1: The measuring device 15 is installed on one side of the hinge device 1, and the measuring device 15 and the shaft hole of the hinge device 1 are kept concentric. S2: Place the hinge shaft 16 in the adjustment assembly 8, adjust the telescopic assembly so that the first clamping assembly 10 abuts against the hinge shaft 16, and the second clamping assembly 11 does not abut against the hinge shaft 16. The Z-axis moving assembly 5 drives the support plate 6 to move vertically, and the X-axis moving assembly 3 drives the support frame 7 to move horizontally, so that the hinge shaft 16 is aligned with the position to be installed. S3: The jack 14 is driven by the Y-axis moving component 4. During the process of the jack 14 pushing the hinge shaft 16 into the hinge device 1, the measuring device 15 provides feedback on the vertical and horizontal offset of the hinge shaft 16. The first distance sensor 806 provides feedback on the distance between the first distance sensor 806 and the end face of the hinge shaft 16. Based on the feedback measurement data, the position of the hinge shaft 16 is adjusted by the Z-axis moving component 5, the X-axis moving component 3 and the adjusting component 8, and the hinge shaft 16 is pushed into the hinge device 1. The hinge shaft 16 is then installed.

[0023] S3 is specifically: Since the hinge shaft 16 is a stepped shaft with shaft segments of different diameters, according to the diameter of the shaft segments from large to small, this embodiment simply divides it into larger shaft segments and smaller shaft segments; The first distance sensor 806 is used to measure the distance between the first distance sensor 806 and the end face of the hinge shaft 16, and is preset with a first preset distance, a second preset distance, and a third preset distance: when the connecting part of the larger shaft segment and the smaller shaft segment is located between the first clamping member group 10 and the second clamping member group 11 of the second adjustment assembly 802, the distance between the first distance sensor 806 and the end face of the hinge shaft 16 is the first preset distance; when the larger shaft segment moves to the second clamping member group 11 in the second adjustment assembly 802, the distance between the first distance sensor 806 and the end face of the hinge shaft 16 is the second preset distance; when the connecting part of the larger shaft segment and the smaller shaft segment is located between the first clamping member group 10 and the second clamping member group 11 of the third adjustment assembly 803, the distance between the first distance sensor 806 and the end face of the hinge shaft 16 is the third preset distance.

[0024] During the process of jack 14 pushing hinge shaft 16 into measuring device 15, when the measurement result of first distance sensor 806 reaches the first preset distance, jack 14 stops working, the first telescopic component group 12 in adjustment component 2 802 extends, the second telescopic component group 13 shortens, so that the first clamping component group 10 in adjustment component 2 802 abuts against the larger shaft section, and the second clamping component group 11 does not contact the smaller shaft section. After adjustment, jack 14 continues to work. When the measurement result of the first ranging sensor 806 reaches the second preset distance, the jack 14 stops working, the second telescopic component group 13 in the second adjustment component 802 extends, the first telescopic component group 12 shortens, so that the second clamping component group 11 in the second adjustment component 802 abuts against the larger shaft section, and the first clamping component group 10 does not contact the larger shaft section. After adjustment, the jack 14 continues to work. When the measurement result of the first ranging sensor 806 reaches the third preset distance, the jack 14 stops working, the first telescopic component group 12 in the adjustment component 3 803 extends, the second telescopic component group 13 shortens, so that the first clamping component group 10 in the adjustment component 3 803 abuts against the larger shaft section, and the second clamping component group 11 does not contact the smaller shaft section. After adjustment, the jack 14 continues to work. Step S3 above describes the movement of the hinge shaft 16 on the adjustment assembly 8. Since the hinge shaft 16 is a stepped shaft with different end diameters, the position of the clamping member needs to be adjusted in real time to avoid obstruction of the movement of the hinge shaft 16. The above steps describe the movement of the hinge shaft 16 with the smaller diameter end in front and the larger diameter end behind. This is only for describing the principle. The movement of the hinge shaft 16 on the adjustment assembly 8 described in this embodiment can be used for the movement of hinge shafts 16 with multiple shaft segments of different diameters on the adjustment assembly 8.

Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
