Description

Technical Field

[0001] This utility model relates to the field of elevator inspection tooling technology, specifically to a gap measuring device for elevator inspection and testing. Background Technology

[0002] Elevator structures are designed and manufactured with a certain amount of expansion joints to ensure the normal and safe operation of the equipment after installation. However, in actual use, the expansion joints of elevator structures need to be controlled within a certain range. Excessive expansion joints can cause structural functional obstacles between the two sides of the equipment during use, while insufficient expansion joints will not meet the design requirements between the structures. When it comes to the safety monitoring of elevator products, since most workpieces are sent for inspection in an assembled state, decorative panels are installed on the surface of the structural components, which obstructs some structural gaps. This makes it difficult for conventional probe measuring equipment to provide simple and intuitive feedback on changes in measurement parameters, especially gap depth parameters, making this inspection time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a gap measuring device for elevator inspection and testing. This device features an adjustable standard parameter probe and an elastic telescopic support structure, allowing for easy insertion of the probe into the gap and ensuring it reaches the bottom.

[0029] like Figure 1-8 As shown, the specific implementation adopts the following technical solution:

[0030] It includes a frame 9 and a mounting sleeve 2, wherein the mounting sleeve 2 is inserted inside the frame 9;

[0031] The mounting sleeve 2 includes a fixing sleeve 2-1 and a cover 2-2, wherein the cover 2-2 covers and fastens to the left port of the fixing sleeve 2-1;

[0034] Spring 12 is sleeved and fixed on guide rod 10, and the rear end of spring 12 abuts against the front end wall of guide sleeve 11.

[0035] The threaded rod 3 is screwed onto the front end plate of the cover 2-2 via a bearing, and the rear end of the threaded rod 3 is screwed onto the rear inner wall of the cover 2-2 via a bearing.

[0036] Mounting base 4 is threadedly fitted onto threaded rod 3. Guide grooves 7 are integrally formed on the inner wall of cover 2-2 and the inner wall of fixing sleeve 2-1. The left and right ends of mounting base 4 are respectively slidably set in the guide grooves 7 on the left and right sides.

[0037] Connecting sleeve 5, the connecting sleeve 5 is fixedly mounted on the mounting base 4, and the rear end of the connecting sleeve 5 is movably mounted on the rear end plate of the fixed sleeve 2-1;

[0038] The support rod 8 is fixedly installed on the inner wall of the front end of the fixed sleeve 2-1, and the support rod 8 is movably inserted into the front port of the connecting sleeve 5.

[0039] The connecting bolt 6 is fixedly mounted on the probe 1 and is threadedly inserted into the rear end of the connecting sleeve 5.

[0040] Ring sleeve 14, which is movably sleeved on the outside of mounting sleeve 2;

[0041] The ring sleeve 14 includes a connecting frame 14-1 and a mounting frame 14-2, wherein the left end of the connecting sleeve 5 is open, and the mounting frame 14-2 is embedded and fixed in the left port of the connecting frame 14-1;

[0042] Support rail 19, which is fixedly mounted on the outer side wall of connecting frame 14-1;

[0043] The support slider 18 is fixedly installed on the right inner wall of the frame 9 and is movably mounted on the support slide rail 19.

[0044] Guide slider 16, the guide slider 16 is fixedly mounted on the inner side wall of the mounting bracket 14-2;

[0045] The guide slide rail 15 is fixedly installed on the outer side wall of the cover 2-2, and the guide slider 16 is slidably mounted on the guide slide rail 15. The guide slide rail 15 is spirally arranged.

[0046] The guide wheels 13, there are four guide wheels 13, and they are respectively rotated to the four rear corners of the frame 9 via a rotating shaft.

[0047] When using this device, it is used to detect the depth of the gap in a workpiece, thereby checking whether the bottom of the gap is flat and whether the gap depth meets the parameter standards. Depending on the different detection indicators, a corresponding probe 1 is selected and screwed onto the connecting sleeve 5 using the connecting bolt 6 on the probe 1, thus installing the probe 1 on the device. Next, rotating the threaded rod 3 pushes the mounting base 4 to move, which in turn moves the connecting sleeve 5. The mounting base 4 moves back and forth guided by the guide groove 7, and the connecting sleeve 5, fitted onto the support rod 8, moves back and forth, thereby moving the probe 1 to adjust its position. The position is adjusted so that the extension length of probe 1 is adjusted so that when probe 1 is inserted into the gap and guide wheel 13 abuts against the workpiece surface, and probe 1 abuts against the bottom of the gap and the gap is at the standard depth, the indicator needle 17 is in a flat position; after adjusting the extension length of probe 1 to the design value of the gap, probe 1 is inserted into the gap until probe 1 abuts against the bottom of the gap, and the frame 9 is pushed so that guide wheel 13 abuts against the surface of the workpiece. At this time, guide sleeve 11 slides forward on guide rod 10 and spring 12 is compressed and contracted. Then the device is moved left or right along the direction of the gap, so that the device... The device slides on the surface of the workpiece via guide wheel 13; spring 12 holds the support sleeve backward, thereby pushing the fixed sleeve 2-1 and the cover 2-2, which in turn pushes the threaded rod 3 on the cover 2-2 to the mounting seat 4. The mounting seat 4 pushes the probe 1 through the connecting sleeve 5, so that the probe 1 always remains against the bottom of the gap. When the gap depth increases, the probe 1 moves backward, causing the mounting sleeve 2 to move backward, that is, the cover 2-2 drives the guide rail 15 to move backward. Conversely, when the gap depth decreases, the probe 1 moves forward, and the probe 1 drives the guide rail 15 to move forward through the mounting sleeve 2. The support slider 18 on the frame 9 guides the rotation of the support slide rail 19 on the ring 14. The connecting frame 14-1 and the mounting frame 14-2 of the ring 14 are fixed in the front and rear positions with the frame 9. When the guide slide rail 15 moves backward, i.e. the gap becomes deeper, the guide slide rail 15 pushes the guide slider 16 to rotate counterclockwise. The guide slider 16 drives the indicator needle 17 to swing downward through the mounting frame 14-2. Conversely, when the gap becomes shallower, the indicator needle 17 swings upward. By observing the direction and amplitude of the up and down swing of the indicator needle 17, the depth and amplitude of the gap in the workpiece can be obtained.

[0048] Compared with the prior art, the beneficial effects of this utility model are:

[0049] 1. This device has a guide rod 10 on the frame 9, a guide sleeve 11 on the mounting sleeve 2, and a guide wheel 13 on the frame 9. The probe 1 is installed in the mounting sleeve 2, and a spring 12 is installed on the guide rod 10. This allows the frame 9 to be pressed against the surface of the workpiece, so that the probe 1 is inserted into the gap of the workpiece and abuts against the bottom of the gap, thereby moving the frame 9. When the depth of the gap changes, the probe 1 abuts against the bottom of the gap, thereby driving the mounting sleeve 2 to move back and forth.

[0050] 2. This device has a rotatable guide ring 14 on the frame 9, and an indicator needle 17 on the mounting bracket 14-2 of the ring 14. A spiral guide rail 15 is provided on the cover 2-2 of the mounting sleeve 2, and a guide slider 16 that cooperates with the guide rail 15 is provided on the mounting bracket 14-2. When the mounting sleeve 2 moves back and forth, it drives the ring 14 to swing, which in turn drives the indicator needle 17 to swing. The depth of the gap can be judged by the swing direction and swing amplitude of the indicator needle 17.

[0051] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
