Technical Field
[0001] The utility model relates to the technical field of elevator maintenance, and particularly relates to a gap detection device for elevator maintenance. Background Art
[0002] The measurement of the gap between elevator door leaves and the dimensions of the sill of the landing door and car door is an important inspection item during the elevator inspection process, but it is also the most cumbersome item. Not only are there many measurement data, but also since most of the detection parts are narrow spaces, it is difficult to read the data, resulting in low inspection and detection efficiency. A feeler gauge is a commonly used tool for inspecting elevator gaps, but the feeler gauge can only inspect the gaps into which the feeler gauge can be inserted, and cannot detect the internal dimensions of the gaps, nor can it detect whether the inside of the gaps is uniform.

[0003] Aiming at the above deficiencies in the prior art, the utility model provides a gap detection device for elevator maintenance, and its purpose is to solve the problems that the feeler gauge can only inspect the gaps into which the feeler gauge can be inserted, cannot detect the internal dimensions of the gaps, and cannot detect whether the inside of the gaps is uniform, etc.
[0004] In order to achieve the above utility model purpose, the technical scheme adopted by the utility model is as follows:
[0005] A gap detection device for elevator maintenance includes a feeler gauge body. A stepped hole is provided in the feeler gauge body. A first spring is arranged in the stepped hole. A thimble is arranged at the top of the first spring. A wedge-shaped block is fixedly arranged at one end of the thimble close to the first spring. A measuring scale is slidably connected in the feeler gauge body. An installation groove is provided in the feeler gauge body. A second spring is arranged in the installation groove. A limiting plate is fixedly arranged on the measuring scale.
[0006] Further, the end of the thimble away from the first spring is conical.
[0007] Further, scale lines are provided on the measuring scale.
[0008] Further, the measuring scale abuts against the wedge-shaped block.
[0009] Further, the second spring is sleeved on the measuring scale.
[0010] Further, the second spring is located on the side of the limiting plate away from the wedge-shaped block.
[0011] The beneficial effects of the utility model are as follows:
[0012] A gap detection device for elevator maintenance according to the present utility model, through the provided first spring and thimble, press the thimble, insert the thickness gauge body into the elevator gap, move the thickness gauge body, the internal size of the gap can be detected, the thimble drives the wedge block to move, and the wedge block drives the measuring scale to move, and the uniformity of the elevator gap can also be detected. The structure of this device is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.
[0020] In order to make the content of the present utility model easier to be clearly understood, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model.
[0021] As Figures 1 to 3 shown, a gap detection device for elevator maintenance includes a thickness gauge body 1, and a step hole 2 is formed in the thickness gauge body 1.
[0022] A first spring 3 is arranged in the step hole 2, a thimble 4 is arranged at the top of the first spring 3, and the end of the thimble 4 away from the first spring 3 is conical. When detecting the elevator gap, press the thimble 4 to make the thimble 4 retract into the step hole 2, and insert the thickness gauge body 1 into the elevator gap.
[0023] A wedge block 5 is fixedly arranged at the end of the thimble 4 close to the first spring 3. Move the thickness gauge body 1, and the thimble 4 and the wedge block 5 move with the change of the gap size.
[0024] A measuring scale 6 is slidably connected inside the feeler gauge body 1. Scale lines 10 are provided on the measuring scale 6. The measuring scale 6 is in contact with a wedge-shaped block 5, and the movement of the wedge-shaped block 5 drives the movement of the measuring scale 6.
[0025] An installation groove 7 is formed inside the feeler gauge body 1. A second spring 8 is provided inside the installation groove 7. The second spring 8 is sleeved on the measuring scale 6. A limiting plate 9 is fixedly provided on the measuring scale 6. The second spring 8 is located on the side of the limiting plate 9 away from the wedge-shaped block 5.
[0026] When reading the elevator gap, subtract the scale of the scale line 10 relative to the feeler gauge body 1 when the feeler gauge body 1 is inserted into the elevator gap from the scale of the scale line 10 relative to the feeler gauge body 1 when the feeler gauge body 1 is not inserted into the elevator gap, which is the size of the elevator gap. Move the feeler gauge body 1 and observe the change of the scale line 10 on the measuring scale 6 relative to the feeler gauge body 1, and the uniformity of the elevator gap can be detected.
[0027] The above are only the preferred embodiments of the utility model patent, and are not intended to limit the utility model patent. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model patent shall be included within the protection scope of the utility model patent.
