DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0019] Embodiment 1

[0020] Reference Figure 1-Figure 3A device for measuring water accumulation during construction of an elevator shaft comprises a towing cart 1, a fixing frame 2 is placed on one side of the top of the towing cart 1, connecting ears 3 are welded on both sides of the top of the fixing frame 2, a fixing box 4 is embedded at the bottom of the inner side of the fixing frame 2, and a measuring rod 5 is slidably embedded inside the fixing box 4. In order to measure the irregular surface of the bottom end of the elevator shaft, a plurality of slots 6 are respectively provided on the top of both sides of the measuring rod 5 on the inner side of the fixing box 4, and a fixed rotating shaft 8 is embedded at both ends of the inner side of the slot 6. A limiting paddle 7 is welded and clamped in the middle of the fixed rotating shaft 8. In order to limit the measuring rod 5 when it slides up without interference, a reset spring 9 is sleeved on the outer side of the fixed rotating shaft 8, and a limiting plate slide groove 10 is provided on the top of both sides of the fixing box 4, and a limiting plate is slidably embedded inside the limiting plate slide groove 10. 11. A limiting rod 17 is embedded in the inner side of the limiting plate 11. In order to reset the measuring rod 5, the limiting rod 17 is embedded in one end of the inner side of the fixing box 4 and limits the limiting paddle 7. One end of the reset spring 9 is connected to the measuring rod 5, and the other end of the reset spring 9 is connected to one end of the limiting paddle 7. A support column 12 is fixed to the middle of the top of the drag cart 1 by bolts, and a hanger 13 is welded to the top of one side of the support column 12. A receiving and discharging motor 14 is installed on the inner end of the hanger 13 through the base. The transmission end of the receiving and discharging motor 14 passes through the hanger 13 and is connected to a double-layer pulley rod 15. Two steel wire ropes 16 are wound around the outside of the double-layer pulley rod 15. The bottom ends of the steel wire ropes 16 are respectively connected to the connecting ears 3 welded on both sides of the top of the fixing frame 2, so that the measuring mechanism can be quickly collected and put down.

[0021] Working principle: First, the operator pushes the towing trolley 1 to the top side of the elevator shaft, and then extends the hanger 13 welded by the support column 12 on the top side of the towing trolley 1 to the top of the elevator shaft. After the fixation is completed, start the reciprocating motor 14 installed through the base at the inner end of the hanger 13. At that time, the reciprocating motor 14 will drive the double-layer pulley rod 15 connected to its transmission end to rotate, and the double-layer pulley rod 15 will release the steel wire rope 16 wrapped around its outer side by rotation. As the steel wire rope 16 descends, the fixed frame 2 fixedly connected at one end of the steel wire rope 16 will also descend together. As the fixed frame 2 descends, the fixed box 4 embedded in the inner side of the fixed frame 2 will also descend together, until the measuring rod 5 slidably embedded in the inner side of the fixed box 4 enters the water and touches the bottom;

[0022] If any one of the three measuring rods 5 touches the bottom of the elevator shaft first and before the other two do not touch the bottom, it will shrink as it descends. The measuring rod 5 that touches the bottom will shrink due to the resistance in the descending direction, and the measuring rod 5 will slide upward inside the fixed box 4. As the sliding proceeds, a number of limit paddles 7 embedded in the top of both sides of the measuring rod 5 will rotate through the fixed rotating shafts 8 embedded on both sides when sliding upward, thereby passing through the limit plug 17 that limits the limit paddle 7. Since the limit paddle 7 can only rotate in one direction, the limit paddle 7 cannot pass through the limit of the limit plug 17 by rotating in the opposite direction during the stopping time after the limit paddle 7 passes through the limit plug 17. This ensures that the measuring rod 5 will not be stopped by its own weight during the upward pulling process after the detection is completed. The amount of water will slide down, thus affecting the final measurement result. After the wire rope 16 bends, it means that the measuring rod 5 has completely contacted the bottom of the elevator shaft. At that time, the measuring rod 5 is retracted, and then the length displayed on one side of the retracted measuring rod 5 is added to the height of the fixed frame 2 and the length of the wire rope 16 with scale, and the water depth at the corresponding position of this measuring rod 5 can be calculated. After the measurement is completed, the limit plug 17 can be pulled out from the inside of the limit plate 11 to reset the measuring rod 5. After the reset of the measuring rod 5 is completed, the limit plug 17 is inserted into the inside of the limit plate 11. The advantage of this design is that large-scale measurements can be carried out at one time to increase the detection rate. At the same time, a preliminary understanding of the bottom surface of the elevator shaft can be obtained, which can prevent the operator from stepping on empty space when going down.

[0023] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
