Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a tool for detecting a disc-type support frame. Background Art

[0002] The disc-type scaffolding is also called the disc-type scaffolding. The support frame includes vertical poles, horizontal poles and diagonal poles. The vertical poles are the main supporting components of the disc-type scaffolding. The disc-type scaffolding needs to be tested for mechanical properties before leaving the factory to ensure that the support coefficient of the support frame is within the qualified threshold.

[0003] In order to improve the scope of application when testing disc-type support frames, the existing technology has made many improvements to the tools for testing disc-type support frames, such as the patent with patent publication number CN218823596U, which discloses a disc-type scaffolding mechanical properties tester, which includes a support frame, a pressure supply mechanism and a support cylinder. The pressure supply mechanism includes a first telescopic member, a support frame, a first pressure supply member and a second pressure supply member. The top of the first telescopic member is fixedly connected to the top of the support frame, and the support frame is fixedly installed at the bottom output end of the first telescopic member. The first pressure supply member is installed at the center position of the top of the support frame, and the second pressure supply member is spaced around the bottom side of the support frame. The support cylinder is arranged at the bottom of the support frame, and the support cylinder and the second pressure supply member are arranged in a one-to-one correspondence. This utility model performs mechanical property testing on unit cell columns. Compared with the single mechanical testing of structures such as columns, it has a wider scope of application and provides convenience for testing.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative document, several disc-type scaffolds are placed between the support cylinder and the second pressure supply member, and pressure is applied through the first pressure supply member to perform mechanical testing on the disc-type scaffold. In reality, there are many types of cross bars of disc-type scaffolds, including 1.5 meters, 1.2 meters, 0.9 meters, 0.6 meters, 0.45 meters and 0.3 meters. The cross bars are used in conjunction with the vertical poles to form a stable scaffolding structure. At least four vertical poles and several cross bars are required to form a stable scaffold. Therefore, when performing mechanical testing on the disc-type scaffold, the cross bars need to be installed to accurately detect the support coefficient value of the entire scaffold. When testing cross bars and vertical poles of different lengths, the position of the above-mentioned support cylinder and the second pressure supply member needs to be adjusted. In the above-mentioned comparative document, if both need to be adjusted, it is more troublesome. Therefore, this field urgently needs to improve the tools for testing disc-type support frames to solve the defects of the existing technology. Utility Model Content

The facing surfaces of the two carrying plates 3 are slidably connected with a plurality of moving rack plates 4 with their ends facing each other, and a limit plate 5 is evenly provided on one side of each moving rack plate 4. A driving unit 6 is provided on each carrying plate 3, and the driving unit 6 is used to simultaneously drive a plurality of moving rack plates 4 to move toward or away from each other, and each moving rack plate 4 is provided with an adjusting unit 7 for moving the carrying plate 3 along the length direction of the moving rack plate 4. The driving unit 6 includes a driving motor 8 fixedly installed on one side of the carrying plate 3. A circular rotating gear ring 9 is rotatably connected inside the carrier plate 3, and one side of the rotating gear ring 9 is in contact with the side surfaces of several moving rack plates 4. Several gears 10 meshing with the side surfaces of the rotating gear ring 9 are rotatably connected inside the carrier plate 3, and the gears 10 mesh with both the rotating gear ring 9 and the moving rack plate 4. The thickness of the gear 10 is greater than the thickness of the rotating gear ring 9. The adjusting unit 7 includes a sliding block 11 provided on one side of the limit plate 5, and a sliding groove 12 adapted to the sliding block 11 is provided on one side of the moving rack plate 4. An adjusting screw 13 is rotatably connected inside the sliding groove 12, and the adjusting screw 13 passes through the sliding block 11 and is threadedly connected to the sliding block 11. One end of the adjusting screw 13 extends to the outside of the moving rack plate 4 and its end is threadedly connected to the first limiting nut 14.

[0032] Specific implementation methods in this embodiment: The telescopic device 2 and the drive motor 8 mentioned above can be purchased on the market. They are mature technologies and have been fully disclosed. Therefore, they will not be repeated in the specification. The drive motor 8 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power line. The telescopic device 2 is connected to the hydraulic station through an oil pipe, and the hydraulic station is provided with a pressure gauge. When pressure is applied to the disc-type support frame, the detection value is recorded by the pressure gauge, and the main controller can be a conventional known device such as a computer that plays a control role. When it is necessary to detect the disc-type support frames with different cross bar lengths, by starting the drive motor 8, the output end of the drive motor 8 drives a gear 10 to rotate, and the gear 10 drives the rotating gear ring 9 to rotate in the carrier plate 3. When the rotating gear ring 9 rotates, it drives other gears. After the cam 5 is in the working state, the gear 10 is rotated, and the gears 10 drive the movable rack plate 4 to move toward or away from each other, and the position of the limit plate 5 on one side of the movable rack plate 4 is adjusted. After the position of the limit plate 5 is adjusted, the column of the buckle type support frame is placed in the corresponding limit plate 5 at the bottom, and the cross bar is installed between the adjacent columns. Start the telescopic device 2, the telescopic lower end of the telescopic device 2 drives the upper bearing plate 3 to move down, and the limit plate 5 is against the upper ends of the columns, and the position of the columns is adjusted again to ensure that the columns are completely in contact with the limit plates 5. Start the telescopic device 2 again to drive the upper bearing plate 3 to move down, apply pressure to the columns, and observe their deformation and the value on the pressure gauge to complete the detection of the buckle type support frame, improve the applicable scope of the overall detection device for the buckle type support frame, and the operation of adjusting the position of the limit plate 5 is simple and quick.

[0033] Under normal circumstances, the cross bar lengths of each group of detection disc-type support frames are the same. Of course, there are also cases where the cross bar lengths of the disc-type support frames are different. At this time, it is necessary to adjust the position of the limit plate 5 on the movable rack plate 4 by rotating the adjusting screw rod 13. When the adjusting screw rod 13 rotates, the sliding block 11 is driven to slide in the sliding groove 12. When the sliding block 11 slides, it drives the limit plate 5 to move, and then adjusts the position of the limit plate 5. When the position of the limit plate 5 is adjusted to the appropriate position, tighten the first limit nut 14 to limit and fix the position of the adjusting screw rod 13, thereby further improving the detection application range of the disc-type support frame.

[0034] Example 2

[0035] See also Figure 6 and Figure 7This embodiment includes the above embodiment, which further includes: two symmetrical and arc-shaped clamping plates 15 are provided in the limiting plate 5, and two symmetrical first limiting bolts 16 are passed through and threadedly connected to the side of the limiting plate 5. The first limiting bolt 16 is rotatably connected to one side of the clamping plate 15, and a second limiting nut 17 is threadedly connected to the side of the first limiting bolt 16.

[0036] The specific implementation method of this embodiment is as follows: when the upper and lower ends of the column are both against the limit plate 5, by rotating the first limit bolt 16, the first limit bolt 16 drives the clamping plate 15 to move toward the column, and the two clamping plates 15 limit the ends of the column, and tighten the second limit nut 17 to limit and fix the position of the first limit bolt 16, thereby limiting the upper and lower ends of the column, thereby improving the safety factor when performing pressure testing on the disc-type support frame.

[0037] Example 3

[0038] See also Figure 6 and Figure 7 This embodiment includes all the above embodiments, which further includes: a polygonal limit block 18 is fixedly connected to the side of the limit plate 5 away from its opening, a limit groove 19 adapted to the limit block 18 is opened on one side of the sliding block 11, and a stepped hole 20 is opened through the bottom of the limit plate 5. A second limit bolt 21 is provided in the stepped hole 20, one end of which passes through the limit block 18 and is threadedly connected to the bottom of the limit groove 19.

[0039] Specific implementation method in this embodiment: The diameters of the columns of the disc-type support frame are also different. When it is necessary to detect columns with different diameters and large diameter differences, the limit plate 5 needs to be replaced, and the limit block 18 on the side of the adapted limit plate 5 is inserted into the limit groove 19 on the sliding block 11, and the second limit bolt 21 is passed through the stepped hole 20. The end of the second limit bolt 21 passes through the lower limit plate 5 and the limit block 18 and is threadedly connected to the bottom of the limit groove 19. The cross-section of the limit block 18 is polygonal, and the second limit bolt 21 is used to limit and fix the limit plate 5, which facilitates the replacement and installation of the limit plate 5.

[0040] Example 4

[0041] See also Figure 1-Figure 5This embodiment includes all the above embodiments, which further includes: two symmetrical fixed plates 25 are fixedly connected to the side of the detection frame 1, the drive motor 8 is fixedly installed on one side of one of the fixed plates 25, and a spline rod 22 is rotatably connected between the two fixed plates 25. The spline rod 22 passes through two corresponding gears 10 on the two carrying plates 3. The output end of the drive motor 8 passes through the fixed plate 25 and is fixedly connected to one end of the spline rod 22. Several reinforcing ribs 23 are fixedly connected between the side surface of the telescopic lower end of the telescopic device 2 and the upper surface of one of the carrying plates 3. The facing surfaces of the two carrying plates 3 are provided with a cover plate 24, and the cover plate 24 is fixedly installed with the carrying plate 3 by fasteners.

[0042] The specific implementation method in this embodiment: by setting a spline rod 22 with a polygonal cross-section, a driving motor 8 can simultaneously control the limit plates 5 on the two carrying plates 3 to move toward or away from each other, ensuring that the limit plates 5 on the two carrying plates 3 move to the same position, and the column is vertical when located between the two upper and lower corresponding limit plates 5, thereby improving the data accuracy during pressure testing of the disc-type support frame. At the same time, when the telescopic device 2 drives the upper carrying plate 3 to move downward, it slides on the side of the spline rod 22 and will not affect the downward movement of the upper carrying plate 3. The reinforcing ribs 23 increase the strength of the upper carrying plate 3 to prevent the carrying plate 3 from being deformed due to excessive pressure. The cover plate 24 is used to protect the parts in the carrying plate 3. At the same time, the cover plate 24 is detachable and connected with fasteners, which is convenient for installation or later maintenance of the parts in the carrying plate 3.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
