Description

Technical Field

[0001] The utility model relates to the technical field of shaft detection equipment, in particular to an elevator shaft detection device. Background Art

[0002] Before installing the elevator car, the elevator shaft needs to be surveyed. The depth of the elevator shaft, that is, the clearance size from the inner wall of the hall door to the rear wall of the shaft, directly affects the depth of the elevator car and the installation position of the door. When surveying the depth of the elevator shaft, it is necessary to measure the depth data of one side from each floor of the elevator shaft. Through accurate depth measurement, it can be ensured that the elevator car can be installed smoothly and the elevator door can be opened and closed normally;

[0003] When measuring the depth of an elevator shaft, some surveyors will use a measuring ruler or a measuring rod to measure the depth of the elevator shaft. For example, the Chinese utility model patent disclosed in the publication number CN221571274U: A distance measuring ruler for elevator inspection can solve the problem that the position of the measuring ruler is shaken and offset due to the shaking of the staff's hands, thereby causing the actual measured data to deviate too much and reducing the reliability of the inspection result. However, when measuring the depth of an elevator shaft by using the application or traditional telescopic measuring rulers, measuring rods and other measuring tools, the measuring ruler or The extraction, use and storage of the telescopic part of the measuring rod require manual pushing and pulling of the telescopic part several times, which reduces the convenience of operation. At the same time, when measuring the depth of the elevator shaft by holding a telescopic measuring ruler or measuring rod, in order to ensure the horizontality of the measuring ruler or measuring rod, it is necessary to make the two ends of the measuring ruler or measuring rod respectively touch the inside of the elevator shaft. Since the elevator shaft is in a relatively open space, when the personnel hold the measuring ruler or measuring rod and explore the elevator shaft, the personnel stand too close to the hall door of the motor shaft, thereby increasing the safety risk of the personnel's measurement operation.

After the movable rod 2 is installed in the main rod 1 through the pull ring 9 and the connecting block 25, the movable rod 2 can be pulled out in cooperation with the rotating shaft 4 and the limit block 13 when measuring the elevator shaft. The setting of the tension spring 22 is convenient for cooperating with the knob 3, the rotating shaft 4, and the limit block 13 to automatically reset the movable rod 2, thereby improving the operational convenience of the entire device.

[0030] It should be noted that the utility model is an elevator shaft detection device. When measuring the depth of the elevator shaft, the data of the current elevator shaft depth can be first determined according to the drawing, so that the adjustment seat 5 is adjusted to a suitable position on the outside of the main rod 1 through the two first sliders 18, and the fixing screw 17 is rotated so that one end of the fixing screw 17 abuts against the outside of the main rod 1, so that the installation position adjustment of the adjustment seat 5 and the abutment seat 6 can be achieved. Subsequently, when measuring the depth of the elevator shaft, the movable block 26 can be held by hand to adjust the movable block 26. The rod 2 is pushed in the direction away from the knob 3, so that the pull block 26 drives the pull ring 9 to slide outside the main rod 1, and the pull ring 9 also drives the movable rod 2 to move outward inside the main rod 1 through the connecting block 25, and the movable rod 2 drives the inner tube 8 to slide on the rotating shaft 4. When the two third sliding grooves 24 in the inner tube 8 slide on the corresponding limit blocks 13, the rotating grooves 23 on the inner side of the inner tube 8 move to the positions of the two limit blocks 13, because the two third sliding grooves 24 no longer limit the axial movement of the limit blocks 13, the return action of the disc spring 14 is used. The rotating shaft 4 is rotated 90 degrees by force, so that the rotating shaft 4 drives the two limit blocks 13 to rotate 90 degrees in the rotating groove 23. Synchronously, the movable rod 2 stretches the tension spring 22 when it is pulled out and moved in the main rod 1. With the help of the tension of the tension spring 22, one side of the rotating groove 23 is abutted against the rotating shaft 4 and the limit block 13, so as to limit the movable rod 2. Then, one end of the main rod 1 can be held by hand and the side of the abutment seat 6 that is away from the adjustment seat 5 is abutted against the wall of the elevator shaft lobby opposite to the operator, and the main rod 1 can be moved. 1 is pressed toward one side of the wall, so that the main rod 1 drives the adjustment seat 5 to move, and then the adjustment seat 5 moves on the corresponding connecting bolt 7 through the multiple countersunk holes 15 inside and compresses the compression spring 21, so that the main rod 1 drives the movable rod 2 to move a certain distance toward the inner side of the elevator shaft and makes the end of the movable rod 2 away from the main rod 1 contact the inner side of the elevator shaft, so that the main rod 1 and the movable rod 2 are kept in a horizontal posture during measurement by cooperating with the contact seat 6, and the depth data of the elevator shaft can be measured through the scale 12 on the outer side of the main rod 1;

[0031] Then, when the elevator shaft depth data of the current floor is measured, the knob 3 can be manually rotated ninety degrees, so that the knob 3 can drive the rotating shaft 4 to rotate synchronously. Then, the two limit blocks 13 at one end of the rotating shaft 4 rotate in the rotating groove 23 to the side of the corresponding third sliding groove 24, and then the movable rod 2 is pulled into the main rod 1 with the help of the tension of the tension spring 22, so that the movable rod 2 can be quickly reset and moved in the main rod 1, and when the pull ring 9 passes through the interference seat 6 and the adjustment seat 5 in turn, the upper half of the pull ring 9 passes through the gap between the interference seat 6, the adjustment seat 5 and the main rod 1, and the through groove 27 passes through the second slider 20 and the first slider 18 in turn, so that the adjusting seat 5 and the interference seat 6 will not move the pull ring 9 normally on the outside of the main rod 1, and the movable rod 2 can be quickly stored.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
