Description

Technical Field

[0001] The invention relates to the field of sports equipment detection, and in particular to a golf net frame strength detection device and a detection method. Background Art

[0002] Golf nets are facilities used in golf courses and driving ranges. Their main function is to prevent the ball from flying out of the court, protect the safety of players and spectators, and also bring convenience to the operation and management of the golf course. However, as an important facility to protect the surrounding environment and personnel safety, the strength and stability of golf nets are of vital importance. At present, there is a lack of equipment and methods specifically used to test the strength of golf nets in the market, which makes it impossible to effectively test the nets.

[0003] In the prior art, a large number of strength detection equipment and methods for steel structure grids are also disclosed. Among them, a Chinese patent with publication number CN116448583A discloses a steel structure grid strength detection equipment, including a first support plate and a support frame; the support frame is fixedly connected to the front upper part of the first support plate; a first telescopic cylinder is fixedly connected to the first support plate, and the telescopic end of the first telescopic cylinder is fixedly connected to the second support plate; a driving unit is connected to the middle part of the second support plate, and the driving unit includes a motor; a plurality of first counterweight blocks are inserted between the two second round rods, and the plurality of first counterweight blocks are stacked; a sleeve is fixedly connected to the middle part of the upper side of the support frame; a sliding rod is slidably connected to the inner side of the sleeve; and a circular plate is fixedly connected to the lower side of the sliding rod.

[0004] When the above-mentioned prior art is in use, the steel structure grid to be tested is manually fixed in the factory and set above the device, and then the suspension assembly is fixed to the middle of the steel structure grid. Then, the first telescopic cylinder and the motor are coordinated to control the number of first counterweight blocks required to be hung on the circular plate, and the required first counterweight blocks are separated from the remaining first counterweight blocks to achieve continuous strength testing of different weights on the steel structure grid. The first counterweight block is fixed by the sleeve and the sliding rod, so that the circular plate cooperates with the first counterweight block.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-Figure 8 Embodiments of the present invention are described in detail.

[0038] The embodiment of the present application discloses a golf net frame strength detection device, which explains that the golf net frame strength detection device of the present application is mainly used in the process of detecting the net frame, and can perform strength detection on the net frame frame and the net in terms of technical effect, thereby effectively reducing the flow of defective net frames into the market, especially in the process of detecting the net, the net can be hammered continuously and the position of the hammering will be constantly changed, so as to achieve a comprehensive detection of the net, thereby avoiding the problem of incomplete and inaccurate detection. Furthermore, the golf net frame strength detection device of the present application can also perform strength detection on the net frame frame while detecting the net, thereby reducing the detection time of the net frame and effectively ensuring the detection efficiency of the net frame of the present application.

[0039] Embodiment 1:

[0040] Reference Figure 1 As shown, in order to realize the strength detection of the frame and the net at the same time, specifically, a golf net strength detection device is provided in this embodiment, including a base plate 1, a supporting unit 2, a net detection unit 3 and a frame detection unit 4 are installed on the upper end of the base plate 1, a controller 5 is arranged on the upper end of the base plate 1, the net detection unit 3 includes a bidirectional motor 31 arranged on the upper end of the base plate 1 through a motor frame, the bidirectional motor 31 and the controller 5 are electrically connected, a transmission rod 32 is installed on the upper end of the output shaft of the bidirectional motor 31, and the transmission rod 32 is sequentially provided with a reciprocating component 33, a telescopic component 34 and a working component 35 along its axial direction from bottom to top.

[0041] Furthermore, in this embodiment, the frame detection unit 4 includes an extension plate 41 installed on the side wall of the base plate 1, a hydraulic cylinder 43 is provided at the upper end of the extension plate 41 through a fixing ring 42, the hydraulic cylinder 43 is electrically connected to the controller 5, a detection component 44 is installed above the hydraulic cylinder 43, and the supporting unit 2 includes a support rod 21 arranged at the four corners of the upper end of the base plate 1, and a receiving component 22 is installed at the upper end of the support rod 21.

[0042] It should be noted that the controller 5 used in the present invention is a prior art, which is mainly used to control the start and stop of the hydraulic cylinder 43 and the bidirectional motor 31, and its working principle will not be described in detail here.

[0043] In actual application, the grid to be inspected is first placed above the receiving component 22, and then the detection component 44 is driven to move upward by the hydraulic cylinder 43. When the detection component 44 moves to the highest point, it is hooked on the grid frame, and then the telescopic end of the hydraulic cylinder 43 moves downward to separate it from the detection component 44, and the weight of the detection component 44 is used to inspect the grid frame, and the grid can be fixed during the inspection, thereby achieving the fixation and inspection of the grid frame, increasing the linkage and reducing the cost; at this time, the bidirectional motor 31 is started, and the output shaft of the bidirectional motor 31 drives the transmission rod 32 to rotate, and the transmission rod 32 drives the reciprocating component 33, the telescopic component 34 and the working component 35 to inspect the net, thereby achieving simultaneous inspection of the grid frame and the net, reducing the inspection time and increasing the inspection efficiency.

[0044] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in order to effectively fix the frame and achieve the detection of the net, based on this, in this embodiment, the receiving assembly 22 includes a square receiving ring 221 installed on the upper ends of multiple support rods 21, and the upper end of the square receiving ring 221 is provided with a plurality of evenly distributed connection groups, and the connection group is composed of a plurality of supporting blocks 222 of the same shape installed at the corners of the upper ends of the square receiving ring 221.

[0045] Furthermore, in this embodiment, the reciprocating component 33 includes a connecting tube 331 slidably mounted on the outer wall of the transmission rod 32, the inner wall of the connecting tube 331 is provided with a plurality of square grooves 332 along the axial direction of the transmission rod 32, the outer wall of the transmission rod 32 is provided with a plurality of contact blocks 333 slidably docked in the square grooves 332, the complex component also includes an annular barrel 334 rotatably mounted on the outer wall of the connecting tube 331, a fixing rod 335 is installed between the annular barrel 334 and a plurality of support rods 21, an annular wave groove 336 is provided on the inner wall of the annular barrel 334, a plurality of evenly distributed matching rods 337 are installed on the outer wall of the connecting tube 331, and the matching rod 337 is in sliding contact with the annular wave groove 336 at one end away from the axis of the transmission rod 32.

[0046] It should be noted that the middle part of the side of the square receiving ring 221 is an inwardly concave through groove, and the upper end surface of the supporting block 222 has an arc-shaped concave surface. When the grid frame is placed on the upper ends of multiple supporting blocks 222, the arc-shaped concave surface can increase the contact area with the grid frame, thereby enhancing the stability of the grid frame during detection. In addition, through the sliding contact between the square groove 332 and the contact block 333, it can be achieved that only relative sliding can be performed between the transmission rod 32 and the connecting tube 331.

[0047] In actual application, first, the grid is placed on the supporting block 222 to be supported and fixed, and then the bidirectional motor 31 is started. The output shaft of the bidirectional motor 31 drives the transmission rod 32 and the connecting tube 331 to rotate, and the connecting tube 331 drives the matching rod 337 to rotate. The end of the matching rod 337 away from the connecting tube 331 is always in sliding contact with the wave groove. During this period, the annular barrel 334 is in a fixed state. Therefore, when the connecting tube 331 drives the matching rod 337 to rotate, the matching rod 337 cooperates with the wave groove to make the connecting tube 331 move up and down while rotating. The connecting tube 331 drives the telescopic component 34 and the working component 35 to move up and down. The working component 35 continuously hammers the net during the up and down reciprocating movement, thereby achieving the detection of the net.

[0048] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in order to be able to perform hammer detection on different positions of the net, based on this, in the present embodiment, the telescopic assembly 34 includes a telescopic cylinder 341 which is arranged at the upper end of the connecting cylinder 331 and is arranged horizontally, and a guide plate 342 located above the telescopic cylinder 341 is commonly provided between the plurality of support rods 21, and a vortex guide hole 343 is provided on the guide plate 342, and the working assembly 35 includes an actuator rod 351 which is installed at one end of the telescopic cylinder 341 away from the connecting cylinder 331 and is parallel to the axis of the transmission rod 32, the actuator rod 351 slides through the vortex guide hole 343, and a push rod 352 is provided on the upper end of the actuator rod 351, and a hemispherical protrusion 353 is installed on the upper end of the push rod 352.

[0049] It should be noted that the telescopic cylinder 341 will automatically extend and retract with the distance between the actuator rod 351 and the connecting cylinder 331. When the actuator rod 351 reaches either end of the vortex guide hole 343 as the connecting cylinder 331 rotates, the bidirectional motor 31 is controlled by the controller 5 to rotate in the opposite direction, so that the actuator rod 351 rotates back and forth along the path of the vortex guide hole 343, thereby preventing the actuator rod 351 from being stuck after reaching either end of the vortex guide hole 343, thereby increasing the reliability of the present invention. The diameter of the protrusion 353 is larger than the mesh diameter of the ball net, thereby preventing the protrusion 353 from entering the space of the ball net and affecting the detection effect.

[0050] In actual application, the telescopic cylinder 341 and the actuator rod 351 are driven to rotate circumferentially by the connecting cylinder 331. The actuator rod 351 drives the push rod 352 and the protrusion 353 to move along the path of the vortex guide hole 343 during the movement. Therefore, when the protrusion 353 reciprocates and hammers the net, the actuator rod 351, the push rod 352 and the protrusion 353 move along the vortex guide hole 343, thereby achieving detection of different positions of the net, thereby performing comprehensive detection and increasing the detection accuracy and efficiency of the net.

[0051] Reference Figure 7 and Figure 8 As shown, in order to realize the strength detection of the grid frame, based on this, in the present embodiment, the detection component 44 includes a tray 441 placed on the top of the telescopic end of the hydraulic cylinder 43, a circular rod 442 is installed at the center of the upper end of the tray 441, a pull rod 443 is installed on the upper end of the circular rod 442, and a pull hook 444 for counterweight detection of the grid is arranged on the upper end of the pull rod 443, a plurality of counterweight blocks 445 are slidingly sleeved on the outer wall of the circular rod 442, a through hole 446 is opened in the middle of the counterweight block 445, a plurality of evenly distributed limit strips 447 are arranged on the outer wall of the circular rod 442, a limit groove 448 matching the limit strip 447 is opened on the inner wall of the through hole 446, and a notch 449 is opened on the side wall of the counterweight block 445 for easy installation and removal.

[0052] It should be noted that the counterweight 445 on the tray 441 can be adjusted according to the detection requirements. When placing the counterweight 445, it needs to be placed on the pull rod 443, so that the pull rod 443 passes through the notch 449 and enters the through hole 446, and then the counterweight 445 is slowly moved downward. During the downward movement, the position of the limit groove 448 and the limit bar 447 need to be aligned to ensure that the limit bar 447 can smoothly pass through the limit groove 448 and continue to descend. The mutual cooperation between the limit groove 448 and the limit bar 447 can ensure that the counterweight 445 will not fall due to accidents during detection, thereby preventing workers from being hit by the counterweight 445 and increasing safety during the detection process.

[0053] In actual application, after the grid is placed on the supporting block 222, the hydraulic cylinder 43 is powered on and started by the controller 5. When the telescopic end of the hydraulic cylinder 43 is extended to the highest point, the hook 444 is located above the grid frame, which is convenient for hanging the hook 444 on the grid frame to ensure that the detection of the grid frame can be carried out normally. Then, the telescopic end of the hydraulic cylinder 43 is controlled to retract downward, so that the hydraulic cylinder 43 drives the tray 441 to move downward. After the hook 444 is hung on the grid frame, the telescopic end of the hydraulic cylinder 43 continues to retract downward and is connected with the tray 441. 41 is separated, and before the separation, the hook 444 of the hydraulic cylinder 43 and the tray 441 will be hung on the frame of the grid, so that the tray 441 is in a suspended state, and the four sides of the grid frame are simultaneously subjected to tension and fixed to prevent the grid from shaking and falling during the subsequent inspection of the net, thereby affecting the inspection progress and increasing the accuracy of the inspection; after the inspection of the grid frame is completed, the telescopic end of the hydraulic cylinder 43 extends upward and lifts up the tray 441, so that the tray 441 can remove the hook from the grid frame, which is convenient for taking out the grid and the subsequent inspection of the grid.

[0054] Embodiment 2:

[0055] Reference Figure 4and Figure 6 As shown, on the basis of the first embodiment, in order to achieve the adjustment of the detection force when the grid is detected, based on this, in this embodiment, a ring is installed on the outer wall of the upper end of the actuator rod 351, and an anti-slip ring is provided on the end of the ejector rod 352 close to the adjustment block 355. A spring groove 354 along its axial direction is provided on the upper end of the actuator rod 351, and an adjustment block 355 is slidably installed on the inner wall of the spring groove 354. A connecting hole is provided on the outer wall of the actuator rod 351, and a plurality of adjusting holes 356 equidistantly distributed along its length direction are provided on one side of the connecting hole. A sliding rod 357 sliding through the adjusting hole 356 is installed on the outer wall of the adjustment block 355. A plurality of shifting holes 359 corresponding to the positions of the adjusting holes 356 are also provided on the outer wall of the actuator rod 351. The shifting holes 359 are connected to the adjusting holes 356 and are vertically distributed. An ejection spring 358 is provided between the upper end of the adjustment block 355 and the inner top wall of the spring groove 354.

[0056] It should be noted that in the actual testing process, the testing standards for different types of grids are not the same, so it is necessary to adjust the size of the impact force on the net; in addition, the ejector spring 358 always applies a driving force to the ejector rod 352, so that the ejector rod 352 drives the protrusion 353 to move upward under the action of the driving force, so as to support and fix the actuator rod 351 and the ejector rod 352, and the anti-slip ring is used to block the sleeve ring to limit the upward movement distance of the ejector rod 352 to prevent the ejector rod 352 from falling off the actuator rod 351.

[0057] In actual application, when it is necessary to adjust the detection strength of the ball net, the sliding rod 357 is moved out of the shift hole 359 to the connecting hole, and then the adjusting block 355 is driven to move upward by the sliding rod 357. During the upward movement of the adjusting block 355, the ejector spring 358 drives the ejector rod 352 and the protrusion 353 to move synchronously, thereby increasing the initial height of the protrusion 353, that is, the protrusion 353 reciprocates up and down to have a greater impact force when hammering the ball net, thereby realizing the adjustment of the impact force of the ball net and increasing the detection effect of the ball net.

[0058] In addition, the present invention also provides a method for detecting the strength of a golf net frame, comprising the following steps:

[0059] S1: Placing the grid: placing the grid to be inspected on the supporting block 222 , and supporting and fixing the grid frame by the supporting block 222 .

[0060] S2: Frame detection: After placing the grid on top of the supporting block 222, the hydraulic cylinder 43 is controlled by the controller 5 to be powered on and started. When the telescopic end of the hydraulic cylinder 43 is extended to the highest point, the hook 444 is located above the grid frame. Then the telescopic end of the hydraulic cylinder 43 is controlled to retract downward, so that the hydraulic cylinder 43 drives the tray 441 to move downward. After the hook 444 is hooked on the grid frame, the telescopic end of the hydraulic cylinder 43 continues to retract downward and separates from the tray 441. Before the hydraulic cylinder 43 and the tray 441 are separated, the hook 444 will be hung on the grid frame, so that the tray 441 is in a suspended state, and the grid frame is simultaneously subjected to tension and fixed on all sides to prevent the grid from shaking and falling at will during the subsequent inspection of the net, thereby affecting the inspection progress.

[0061] S3: Net detection: start the bidirectional motor 31, the output shaft of the bidirectional motor 31 drives the transmission rod 32 and the connecting tube 331 to rotate, and the connecting tube 331 drives the matching rod 337 to rotate. During this period, the annular barrel 334 is in a fixed state. Therefore, when the connecting tube 331 drives the matching rod 337 to rotate, the matching rod 337 cooperates with the wave groove to make the connecting tube 331 move up and down while rotating. The connecting tube 331 drives the telescopic tube 341 and the actuator rod 351 to rotate circumferentially. During the movement, the actuator rod 351 drives the push rod 352 and the protrusion 353 to move along the path of the vortex guide hole 343. Therefore, when the protrusion 353 reciprocates and hammers the net, the actuator rod 351, the push rod 352 and the protrusion 353 move along the vortex guide hole 343, so as to detect different positions of the net.

[0062] S4: Remove the grid: After the grid frame detection is completed, the telescopic end of the hydraulic cylinder 43 extends upward and lifts the tray 441, removes the hook from the grid frame, makes the grid lose its fixing function, and then removes the grid from the supporting block 222.

[0063] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

[0064] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
