DETAILED DESCRIPTION

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] A detection device for elevator door blade, such as Figures 1 to 4 As shown, it includes a bearing seat 1, and the bearing seat 1 is used to place the elevator door knife. A plurality of positioning columns 11 for positioning the elevator door knife are arranged on the bearing seat 1. The positioning columns 11 are adapted to the through holes on the elevator door knife, that is, when placing the elevator door knife, a plurality of positioning columns 11 are passed through the corresponding through holes on the elevator door knife, so that the two cooperate to position the elevator door knife, thereby ensuring the stability of the elevator door knife. Furthermore, a fastener 12 for limiting the position of the elevator door knife is detachably connected to the bearing seat 1, and the fastener 12 is preferably a bolt. A mounting hole for threaded connection with the bolt is provided on the bearing seat 1, and the bolt is threadedly connected to the mounting hole, so that the bolt presses the elevator door knife onto the bearing seat 1, thereby limiting the position of the elevator door knife, further ensuring the stability of the elevator door knife during the detection process, and avoiding the influence of the detection result due to the instability of the elevator door knife.

[0025] The bearing seat 1 is provided with a mounting seat 2, and the mounting seat 2 is provided with an adjusting screw 3 and a push-pull force gauge 4, which is located at one end of the mounting seat 2. A movable block 5 is slidably provided on the mounting seat 2, and the movable block 5 is slidably provided on the mounting seat 2 through a slide rail. The movable block 5 is threadedly connected with the adjusting screw 3, and a force block 6 is provided on the movable block 5. The force block 6 is in an "L" shape. When the adjusting screw 3 is rotated to make the movable block 5 move along the length of the adjusting screw 3, When moving in the same direction, the movable block 5 drives the force block 6 to move gradually close to the side wall of the elevator door knife blade 19 and the end of the push-pull force gauge 4, until the force block 6 can abut against the side wall of the elevator door knife blade 19 and the end of the push-pull force gauge 4, and apply pressure to the elevator door knife blade 19 and the end of the push-pull force gauge 4, so as to perform a force test on the elevator door knife blade 19. According to the test result, it can be judged whether the force condition of the elevator door knife blade 19 meets the standard.

[0026] It should be noted that, since the force block 6 applies pressure to the blade 19 of the elevator door knife and the end of the push-pull force gauge 4 at the same time, the pressure value currently applied by the force block 6 to the push-pull force gauge 4 is measured and displayed by the push-pull force gauge 4. At this time, the pressure value currently applied by the force block 6 to the elevator door knife blade 19 can be known. The user can adjust the pressure applied by the force block 6 to the elevator door knife blade 19 by rotating the adjusting screw 3 according to the real-time pressure value provided by the push-pull force gauge 4, thereby accurately controlling the pressure value applied to the elevator door knife blade 19.

[0027] A connecting portion 13 is integrally provided on the bearing seat 1, and the mounting seat 2 is rotatably connected to the connecting portion 13 via a rotating shaft 14, that is, the mounting seat 2 can be rotated around the rotating shaft 14, and the mounting seat 2 can be in a vertical state or a horizontal state by rotation. When placing the elevator door knife, the mounting seat 2 is rotated to make it in a vertical state, so as to avoid the travel of the elevator door knife being placed on the bearing seat 1.

[0028] When the mounting seat 2 is in a vertical state, the bottom of the mounting seat 2 abuts against the side wall of the connecting portion 13 to limit the mounting seat 2. Moreover, since the lower end of the mounting seat 2 in the vertical state is affected by the push-pull force gauge 4 and has a heavier weight, the mounting seat 2 always remains in a vertical state without external force. There is no need for the operator to support the mounting seat 2 separately, which makes it more convenient to place the elevator door knife.

[0029] A support portion 15 is provided on the bearing seat 1, and the support portion 15 is used to support the mounting seat 2 in a horizontal state. Furthermore, positioning protrusions 16 are provided on both sides of the support portion 15, and the two positioning protrusions 16 cooperate to limit the mounting seat 2 in a horizontal state, thereby ensuring the stability of the mounting seat 2.

[0030] The mounting seat 2 can move along the axial direction of the rotating shaft 14. As the mounting seat 2 moves, the force block 6 overlaps with the projection of the blade 19 of the elevator door knife along the axial direction of the adjusting screw 3, that is, as the movable block 5 moves along the length direction of the adjusting screw 3, the force block 6 can abut against and apply pressure to the blade 19 of the elevator door knife.

[0031] A detection member 7 for applying pressure to the unlocking plate 20 of the elevator door knife and detecting the pressure value is arranged on the bearing seat 1. The detection member 7 includes a mounting seat 2 71, an adjusting screw 2 72, a movable block 2 73, a push-pull force gauge 2 74 and a hook 1 75.

The hook 1 75 is in a "concave" shape. When the adjusting screw 2 72 is rotated to move the movable block 2 73, the hook 1 75 can abut against the unlocking plate 20 of the elevator door knife and apply pressure to the unlocking plate 20 of the elevator door knife.

[0032] It should be noted that when the hook 1 75 applies pressure to the unlocking plate 20, the push-pull force gauge 2 74 can measure the pressure value applied by the hook 1 75 on the unlocking plate 20. The user can change the position of the movable block 2 73, the push-pull force gauge 2 74 and the hook 1 75 by turning the adjusting screw 2 72 according to the real-time pressure value provided by the push-pull force gauge 2 74, and then adjust the pressure applied by the hook 1 75 on the unlocking plate 20, thereby accurately controlling the pressure value applied to the unlocking plate 20.

[0033] A universal seat 17 is provided on the bearing seat 1 , and a dial indicator 9 is provided on the universal seat 17 . The dial indicator 9 is used to measure the displacement distance of the unlocking plate 20 after being subjected to pressure, and the trigger needle of the dial indicator 9 contacts the unlocking plate 20 .

[0034] After the hook 75 applies pressure to the unlocking plate 20, the unlocking plate 20 deflects in the direction of the pressure. The operator measures the deflection distance of the unlocking plate 20 after the pressure according to the dial gauge 9, so as to determine whether the unlocking plate 20 meets the standard. The use of the dial gauge 9 can more accurately obtain the deflection distance of the unlocking plate 20 after the pressure.

[0035] A detection member 28 for applying pressure to the lock hook 21 of the elevator door knife and detecting the pressure value is arranged on the bearing seat 1. The detection member 28 includes a mounting seat 3 81, an adjusting screw 3 82, a movable block 3 83, a push-pull force gauge 3 84 and a pull hook 2 85. The mounting seat 3 81 is arranged on the other side of the bearing seat 1, the adjusting screw 3 82 is arranged on the mounting seat 3 81, the movable block 3 83 is slidably arranged on the mounting seat 3 81 through a guide rod 2, the movable block 3 83 is threadedly connected with the adjusting screw 3 82, the push-pull force gauge 3 84 is arranged on the movable block 3 83, and the pull hook 2 85 is rotatably arranged at the end of the push-pull force gauge 3 84. The pull hook 2 85 is in a "concave" shape. When the adjusting screw 3 82 is rotated to move the movable block 3 83, the pull hook 2 85 can abut against the lock hook 21 of the elevator door knife and apply pressure to the lock hook 21 of the elevator door knife.

[0036] It should be noted that when the pull hook 2 85 applies pressure to the lock hook 21, the push-pull force gauge 3 84 can measure the pressure value applied by the pull hook 2 85 on the lock hook 21. The user can change the position of the movable block 3 83, the push-pull force gauge 3 84 and the pull hook 2 85 by rotating the adjusting screw 3 82 according to the real-time pressure value provided by the push-pull force gauge 3 84, and then adjust the pressure applied by the pull hook 2 85 on the lock hook 21, thereby accurately controlling the pressure value applied to the lock hook 21.

[0037] A universal seat 18 is provided on the bearing seat 1 , and a dial indicator 10 is provided on the universal seat 18 . The dial indicator 10 is used to measure the displacement distance of the lock hook 21 after being pressed. The dial indicator 10 contacts the trigger pin of the lock hook 21 .

[0038] After the pull hook 85 applies pressure to the lock hook 21, the lock hook 21 deviates in the direction of the pressure. The operator measures the distance the lock hook 21 deviates after being subjected to the pressure according to the dial indicator 10, thereby determining whether the lock hook 21 meets the standard. The dial indicator 10 can be used to more accurately obtain the distance the lock hook 21 deviates after being subjected to the pressure.

[0039] The present invention enables an operator to accurately control the pressure values ​​applied to the elevator door knife blade 19, the elevator door knife unlocking plate 20 and the elevator door knife locking hook 21, thereby improving the accuracy and reliability of elevator door knife detection.
