The first driving wheel 110 is rotationally connected to the support structure 400, and the first driven wheel 120 is rotationally connected to the support structure 400, so that the first driving wheel 110 and the first driven wheel 120 can rotate along their own axes. The first driving wheel 110 and the first driven wheel 120 can abut against the first cable 10 to clamp the first cable 10. The rotation of the first driving wheel 110 and the first driven wheel 120 drives the first cable 10 to be unwound.

[0063] The structure and shape of the second lowering transmission member are as follows:

[0064] The second lowering transmission member comprises a second driving wheel 130 and a second driven wheel 140. The second driving wheel 130 is rotationally connected to the support structure 400, and the second driven wheel 140 is rotationally connected to the support structure 400, so that the second driving wheel 130 and the second driven wheel 140 can rotate along their own axes. The second driving wheel 130 and the second driven wheel 140 can abut against the second cable 20 to clamp the second cable 20. The rotation of the second driving wheel 130 and the second driven wheel 140 drives the second cable 20 to be unwound.

[0065] In order to realize synchronous rotation of the first driving wheel 110 and the second driving wheel 130, the first driving wheel 110 and the second driving wheel 130 are both provided with synchronous transmission gears 150, and the two synchronous transmission gears 150 are connected through a synchronous chain so as to make the first driving wheel 110 and the second driving wheel 130 rotate synchronously, and the synchronous lowering assembly 100 further comprises a lowering control crank 160; the lowering control crank 160 is connected with the first driving wheel 110 or the second driving wheel 130, and a user drives the first driving wheel 110 and the second driving wheel 130 to rotate synchronously through the lowering control crank, in addition, the first driving wheel 110 and the second driving wheel 130 have a height difference, and the height position of the first driving wheel 110 is higher than that of the second driving wheel 130, therefore, the lowering control crank is installed on the second driving wheel 130.

[0066] In an optional embodiment, the support structure 400 is fixedly provided with a moving slide rail 170, and the second driven wheel 140 is slidably connected with the moving slide rail 170 so as to move the second driven wheel 140 between the contact position and the release position; when the second driven wheel 140 is located at the contact position, the second driven wheel 140 is in close contact with the second driving wheel 130 to clamp the second cable 20, so as to be able to drive the second cable 20 to be lowered; when the second driven wheel 140 is located at the release position, the second driven wheel 140 is out of position with the second driving wheel 130, so that the second cable 20 cannot be clamped, and the second cable 20 is in a released state, at this time, the lowering height of the second cable 20 can be freely adjusted without affecting the lowering height of the first cable 10.

[0067] The driving wheel is provided with a fixing hook 180, which can be connected with the second driven wheel 140 to limit the driven wheel at the contact position, so as to avoid the second driven wheel 140 from moving along the moving slide rail 170 during operation.

[0068] Regarding the structure of the synchronous recovery assembly 200, in particular:

[0069] The synchronous recovery assembly 200 comprises a first synchronous gear 210, a second synchronous gear 220, a first one-way gear 230 and a second one-way gear 240; the first synchronous gear 210 and the second synchronous gear 220 are meshingly connected, so as to make the first synchronous gear 210 and the second synchronous gear 220 rotate synchronously; the first one-way gear 230 is configured to transmit the rotating driving force of the first synchronous gear 210 to the first wire reel 500, so as to make the first wire reel 500 rotate in the winding direction; the second one-way gear 240 is configured to transmit the rotating driving force of the second synchronous gear 220 to the second wire reel 600, so as to make the second wire reel 600 rotate in the winding direction.

[0070] Specifically, when the cable needs to be recovered, the second synchronous gear 220 rotates counterclockwise, and since the first synchronous gear 210 and the second synchronous gear 220 are meshed and connected, the first synchronous gear 210 rotates clockwise, and the first cable 10 is recovered through the clockwise rotation of the first cable reel 500 driven by the first one-way gear 230. At the same time, the second synchronous gear 220 rotates counterclockwise, and the second cable 20 is recovered through the counterclockwise rotation of the second cable reel 600 driven by the second one-way gear 240.

[0071] In optional embodiments, as shown in FIG. 2, the first one-way gear 230 includes a first gear outer ring 231, a first gear inner ring 232, and a first pawl 233. The first gear outer ring 231 is synchronously connected with the first synchronous gear 210 through a synchronous chain, the first gear inner ring 232 is connected with the first cable reel 500, and the first pawl 233 is connected with the first gear inner ring 232. When the first gear outer ring 231 rotates in the winding direction, the first pawl 233 is clamped with the first gear outer ring 231, so that the first gear outer ring 231 and the first gear inner ring 232 rotate together in the winding direction. The first pawl 233 is configured to enable the first gear inner ring 232 to rotate independently in the winding direction relative to the first gear outer ring 231. Figure 2 In optional embodiments, as shown in FIG. 2, the second one-way gear 240 includes a second gear outer ring 241, a second gear inner ring 242, and a second pawl 243. The second gear outer ring 241 is synchronously connected with the second synchronous gear 220 through a synchronous chain, the second gear inner ring 242 is connected with the second cable reel 600, and the second pawl 243 is connected with the second gear inner ring 242. When the second gear outer ring 241 rotates in the winding direction, the second pawl 243 is clamped with the second gear outer ring 241, so that the second gear outer ring 241 and the second gear inner ring 242 rotate together in the winding direction. The second pawl 243 is configured to enable the second gear inner ring 242 to rotate independently in the winding direction relative to the second gear outer ring 241.

[0072] Figure 3 Specifically, when the first cable 10 and the second cable 20 need to be wound synchronously, the first gear outer ring 231 is driven by the first synchronous gear 210 to rotate clockwise, and since the first pawl 233 is clamped, the first gear inner ring 232 and the first cable reel 500 are driven to rotate clockwise together, and the first cable 10 is wound. At the same time, since the first synchronous gear 210 and the second synchronous gear 220 are meshed and connected, the second synchronous gear 220 drives the second gear outer ring 241 to rotate counterclockwise, and since the second pawl 243 is clamped, the second gear inner ring 242 and the second cable reel 600 are driven to rotate counterclockwise together, and the second cable 20 is wound.

[0073] Specifically, when the first cable 10 and the second cable 20 need to be wound synchronously, the first gear outer ring 231 is driven by the first synchronous gear 210 to rotate clockwise, and since the first pawl 233 is clamped, the first gear inner ring 232 and the first cable reel 500 are driven to rotate clockwise together, and the first cable 10 is wound. At the same time, since the first synchronous gear 210 and the second synchronous gear 220 are meshed and connected, the second synchronous gear 220 drives the second gear outer ring 241 to rotate counterclockwise, and since the second pawl 243 is clamped, the second gear inner ring 242 and the second cable reel 600 are driven to rotate counterclockwise together, and the second cable 20 is wound.

[0074] ​And, due to the arrangement of the first pawl 233 and the second pawl 243, the first winding reel 500 can be rotated clockwise alone, the first gear outer ring 231 does not rotate, the second winding reel 600 can be rotated counterclockwise alone, and the second gear outer ring 241 does not rotate.

[0075] In an alternative embodiment, the synchronous recovery assembly 200 further comprises a recovery control handle 250; the recovery control handle 250 is connected with the first synchronous gear 210 or the second synchronous gear 220, and the user drives the first synchronous gear 210 and the second synchronous gear 220 to rotate synchronously through the recovery control handle 250.

[0076] The synchronous operation device of the detection assembly has the advantages that the synchronous operation device of the detection assembly is simple in structure, convenient to use, and low in cost.

[0077] S1: Before the test starts, the tester calibrates whether the first probe 11 and the second probe 21 are located at the unified height of the hole, if not unified, the first probe 11 is placed at the hole, the fixing hook 180 is loosened, the second driven wheel 140 is pushed to the right side along the moving slide rail 170, the close contact between the second driving wheel 130 and the second driven wheel 140 is loosened, at this time, the length of the second cable 20 is manually adjusted, the second probe 21 is adjusted to the hole, so that the depth of the first probe 11 and the second probe 21 is consistent during the test, after completion, the second driven wheel 140 is retreated to the left side of the moving slide rail 170, the fixing hook 180 is installed, and the position of the second driven wheel 140 is locked.

[0078] S2: When the test starts, according to the test requirements, the drop control handle 160 is rotated clockwise, and the first probe 11 and the second probe 21 are slowly and synchronously dropped.

[0079] S3: When the hole test is completed, the winding reel handle is rotated counterclockwise, under the action of the first synchronous gear 210 and the second synchronous gear 220 and the cooperation of the first one-way gear 230 and the second one-way gear 240, the first winding reel 500 and the second winding reel 600 rotate in opposite directions, the first cable 10 and the second cable 20 are synchronously lifted and recovered, until the first probe 11 and the second probe 21 are completely lifted out of the hole, and the test is completed. If it is found that one of the winding cables is loose during the recovery process, the corresponding winding reel can be manually rotated, under the action of the one-way gear, the first winding reel 500 can be rotated clockwise without affecting the second winding reel 600, and the first cable 10 is tightened alone; similarly, the second winding reel 600 can be rotated counterclockwise without affecting the first winding reel 500, and the second cable 20 is tightened alone.

[0080] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
