Specific implementation mode
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0023] First embodiment:
[0024] As Figure 1 shown, a gap inspection device dedicated to elevator inspection includes: a measuring ruler 1 for measuring the elevator gap, and scale lines 11 are provided on the measuring ruler 1; two sliding frames 2 slidably connected to the measuring ruler 1, and a pointer 21 is provided at the top of the sliding frame 2; a detection piece 3 detachably connected to the sliding frame 2; a bracket 4 provided at the top of the measuring ruler 1, and a slide bar 5 is provided at the top of the bracket 4; a core block 6 slidably connected to the slide bar 5; a connecting rod 7 with two ends respectively hinged to the sliding frame 2 and the core block 6, and the connecting rod 7 is connected to the bracket 4 through a spring 71; handles 61 provided on both sides of the core block 6; a limit component 8 provided on the slide bar 5; and a moving component 9 detachably connected to both sides of the measuring ruler 1.
[0025] The length of the measuring ruler 1 is greater than the length of the general elevator gap. A slideway 12 is opened on the side wall of the measuring ruler 1, and the slideway 12 is parallel to the long side direction of the measuring ruler 1. Ball bearings are provided in the inner wall of the sliding frame 2, and the ball bearings are slidably connected to the slideway 12. Lubricating oil is applied to the ball bearings, and the friction between the ball bearings and the slideway 12 is small, so that the sliding frame 2 can smoothly move along the slideway 12. When the elevator gap changes, the sliding frame 2 can move quickly.
[0026] An opening is provided at the top of the sliding frame 2, and the opening is above the scale line 11. The tip of the pointer 21 is in the same straight line as the edge of the gap. The scale of the gap can be seen at the opening, and the data of the measured elevator gap can be calculated through the data indicated by the pointer 21.
[0027] The bottom of the support 4 is fixedly connected to both sides of the measuring ruler 1. The support 4 gradually tapers upward. The lower part of the support 4 is an overall rectangular frame, and the upper part of the support 4 is an overall trapezoidal frame. The overall contraction of the upper part facilitates reducing the floor area and is convenient for carrying. The top of the support 4 is also provided with a fixed handle 41, and the fixed handle 41 extends away from the measuring ruler 1. The device is lifted by holding the fixed handle 41 with the hand.
[0028] The sliding rod 5 faces the measuring ruler 1. The sliding rod 5 is cylindrical. A retaining piece 51 is provided at the bottom of the sliding rod 5. The diameter of the retaining piece 51 is larger than that of the sliding rod 5. The retaining piece 51 is used to prevent the limit component 8 and the core block 6 from detaching from the sliding rod 5.
[0029] When the core block 6 moves towards the measuring ruler 1, the core block 6 drives the connecting rod 7 to slide towards the support 4, thereby driving the sliding frame 2 and the detection piece 3 to unfold; when the core block 6 moves away from the measuring ruler 1, the core block 6 drives the connecting rod 7 to move towards the sliding rod 5, and the contraction of the connecting rod 7 drives the sliding frame 2 and the detection piece 3 to move closer to the middle of the measuring ruler 1.
[0030] The spring 71 is in a stretched state. Without external intervention, the spring 71 pulls the connecting rod 7 to move towards the end of the measuring ruler 1. In the non - use state, the two sliding frames 2 are located at both ends of the measuring ruler 1.
[0031] The top of the lifting handle 61 is higher than the top of the support 4, and the top of the lifting handle 61 is lower than the top of the fixed handle 41. By pulling the lifting handle 61 upward, the sliding frame is made to move closer to the middle of the measuring ruler 1, so that the scale of the detection piece 3 is reset to zero. During use, the palm is attached to the fixed handle 41, the fingers hook the lifting handle 61, and the lifting handle 61 is pulled upward to move the core block 6 upward, further making the distance between the two detection pieces 3 smaller than the elevator gap. Then, the lifting handle 61 is slowly released. Under the pulling force of the spring 71, the detection piece 3 moves to both sides. When the detection piece 3 is in contact with both sides of the crack, the length of the crack can be obtained through the measuring ruler 1 at this time. When the widths of the developed cracks are inconsistent, the detection piece 3 will automatically change under the pulling force of the spring 71, which is convenient for elevator maintenance personnel to record.
[0032] When inspecting whether the gap width is qualified without recording specific data, the distance between the two detection pieces 3 can be fixed by the limit component 8, and the detection piece 3 can be directly inserted into the gap. The limit component 8 includes a conical sleeve 81 and a fastening nut 82. The conical sleeve 81 is slidably connected to the sliding rod 5. The outer wall of the conical sleeve 81 is provided with threads, and a plurality of notches are formed on the side wall of the conical sleeve 81. The fastening nut 82 is screwed onto the side wall of the conical sleeve 81. The thickness at the notch of the conical sleeve 81 gradually changes. When the fastening nut 82 is at the non-notch position, the conical sleeve 81 turns outwards, and the conical sleeve 81 can slide along the sliding rod 5. When the fastening nut 82 is screwed towards the notch, the fastening nut 82 presses the conical sleeve 81 to contract inwards and clamp the sliding rod 5, making the conical sleeve 81 unable to move, further restricting the core block 6 from moving towards the baffle 51 and preventing the detection piece 3 from expanding outwards. At this time, one can operate by holding the fixed handle 41.
[0033] The moving component 9 includes a connecting column 91 and a universal ball 92. The connecting column 91 and the universal ball 92 are perpendicularly connected. Connecting holes 13 are provided on both sides of the measuring ruler 1. The connecting column 91 can be inserted into the connecting hole 13. By different insertion methods of the connecting column 91, the orientation angle of the universal ball 92 can be changed, and the universal ball 92 can face the bottom surface or the side surface of the measuring ruler 1. When in use, the universal ball 92 fits with the ground on the edge of the crack, and it moves smoothly along the crack.
[0034] The detection piece 3 and the sliding frame 2 are connected by screws, which is convenient for disassembly. The detection piece 3 protrudes towards the bottom of the measuring ruler 1. At this time, the universal ball 92 faces the bottom of the measuring ruler 1. In this case, it is convenient to measure the elevator crack in the horizontal direction.
[0035] Second Embodiment:
[0036] As Figure 2 shown, in this embodiment, the protruding direction of the detection piece 3 is different from that in the first embodiment.
[0037] The detection piece 3 protrudes towards the side of the measuring ruler 1. At this time, the universal ball 92 faces the side of the measuring ruler 1. In this case, it is convenient to measure the elevator crack in the vertical direction.
[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
