Technical Field
[0001] This utility model relates to the field of escalator technology, and in particular to an escalator handrail lip strength testing device. Background Technology
[0002] With the continuous development of technology, people's requirements for the safety performance of various components of escalators are constantly increasing. The handrail belt, which comes into direct contact with passengers, is an important component of escalators, and its strength is closely related to passenger safety. Local bidding and related industry standards have put forward new requirements for the strength of the handrail belt lip. The "handrail belt lip" is the flanged edge on both sides of the cross-section of the escalator handrail belt, shaped like a "lip," hence the name "lip." The handrail belt lip is the flanged edge on both sides of the handrail belt used to hold the guide rail, and it is a key structure to ensure that the handrail belt does not fall off or wobble. Insufficient strength of the handrail belt lip will directly lead to the handrail belt loosening, causing hands to be pinched, falls, or even serious safety accidents. Therefore, measuring the tensile strength of the handrail belt lip is also an important part of reducing the risk of accidents. Utility Model Content

[0021] As attached Figure 1 Appendix Figure 2 The diagram shows a device for detecting the lip strength of an escalator handrail according to this utility model. It includes a horizontal base plate 1, a mounting plate 2, and a digital push-pull force gauge 3. The mounting plate 2 is horizontally slidably connected to the base plate 1, and the digital push-pull force gauge 3 is fixedly connected to the mounting plate 2. (See attached diagram) Figure 3As shown, in this embodiment, a guide groove 13 is machined along the length direction on the base plate 1. The digital push-pull force gauge 3 is fixedly connected to the upper surface of the mounting plate 2. A guide block 14 is installed on the lower surface of the mounting plate 2. The guide block 14 is embedded in the guide groove 13, so that the mounting plate 2 and the base plate 1 are horizontally slidably connected, preventing the mounting plate 2 from wobbling left and right and improving the measurement accuracy. The back of the digital push-pull force gauge 3 has a first mounting hole. The mounting plate 2 is machined with a second mounting hole corresponding to the first mounting hole. The guide block 14 has a third mounting hole. The first bolt 15 passes through the third mounting hole and the second mounting hole in sequence and enters the first mounting hole, so that the digital push-pull force gauge 3, the mounting plate 2 and the guide block 14 are fixedly connected, and the connection is simple and reliable. The base plate 1 has a pressure strip 16 on its upper part. The pressure strip 16 is located on both sides of the mounting plate 2. The two ends of the pressure strip 16 have second bolts 17 connected to the base plate 1. Sleeves 18 are installed on the second bolts 17 to create a gap between the pressure strip 16 and the base plate 1. The mounting plate 2 includes an extension 21 that is inserted between the pressure plate and the base plate 1 to prevent the mounting plate 2 from coming out of the guide groove 13 and to make the movement more stable.
[0022] One end of the mounting plate 2 is connected to a fixed base 4. The fixed base 4 has a first through hole machined parallel to the sliding direction of the mounting plate 2. A support 5 is mounted on the end of the base plate 1 near the fixed base 4. The support 5 has a second through hole corresponding to the first through hole. An adjusting bolt 6 passes through both the first and second through holes. An adjusting nut 7 is screwed onto the adjusting bolt 6. The adjusting nut 7 is located at the end of the support 5 furthest from the fixed base 4. Rotating the adjusting nut 7 changes the distance between the mounting plate 2 and the support 5. A gripping lever 19 is attached to the adjusting nut 7. This lever 19 consists of four bolts made of readily available and simple materials.
[0023] The base plate 1 has a placement area for placing the handrail belt 10 at one end away from the support 5. The placement area has a movable locking plate 8 connected to the hook of the digital push-pull force gauge 3 at one end near the mounting plate 2. The placement area has a fixed locking plate 9 fixedly connected to the base plate 1 at one end away from the mounting plate 2. The fixed locking plate 9 and the movable locking plate 8 are used to hook the two lips of the handrail belt 10 and pull it open.
[0024] A scale 11 is fixedly installed on the base plate 1 along the sliding direction of the mounting plate 2. A pointer 12 is connected to the mounting plate 2 to indicate the value of the scale 11. When the value of the digital push-pull force gauge 3 is 0, the pointer 12 points to 0 on the scale 11. Before use, the fixed clamping plate 9 and the movable clamping plate 8 are clamped onto the lip of the handrail belt 10. The scale of the pointer 12 is adjusted to the "0" position on the scale. The digital push-pull force gauge 3 is turned on to zero the value. The adjusting nut 7 is gradually tightened until the required force for measurement is reached. The value of the scale 11 is observed and the data is read. The required tension data can be measured conveniently and quickly.
[0025] This utility model discloses an escalator handrail lip strength testing device with a simple structure, wide applicability, convenient installation and operation, and reliable fixing method. Tensile force and displacement can be quickly read on this device, with tensile force accuracy up to 0.1N and displacement accuracy up to 0.5mm. The device uses manual control of bolt tightening force, making it easy to control the force magnitude. Combined with the design of pointer 12 and scale 11, it facilitates convenient and accurate reading of the required measurement data, improving testing efficiency.
