Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator maintenance testing devices, specifically an elevator maintenance testing device. Background Technology
[0002] Elevator maintenance testing devices are diverse and play a crucial role in ensuring the safe and efficient operation of elevators and accurately locating potential faults. Among them, the elevator vibration and acceleration / deceleration detector is highly representative and practical. This detector is equipped with a high-sensitivity vibration sensor and a high-precision acceleration sensor: the vibration sensor can accurately capture subtle vibrations during elevator operation, whether it is longitudinal shaking of the car caused by uneven guide rails or lateral swaying caused by uneven tension in the wire ropes, it can be clearly sensed and converted into electrical signals. These signals are quickly sent to the analysis module via data transmission lines; the acceleration sensor focuses on monitoring the dynamic changes during the elevator's starting and braking phases, accurately measuring the acceleration of the elevator from a standstill to the instant of starting, as well as the magnitude and rate of change of deceleration during braking. It quickly determines whether the elevator's vibration and acceleration / deceleration during starting and braking meet the standards and generates an intuitive report, providing maintenance personnel with clear fault indications and maintenance suggestions, helping them to complete elevator maintenance efficiently and accurately.
[0003] However, currently, when using this elevator maintenance testing device, it must first be taken out of the equipment box and then placed on the floor of the elevator car for data testing. During the operation, the staff has to frequently squat down in the running elevator to adjust the device. Because the elevator will shake and slightly bump during operation, it is difficult for the staff to maintain their body stability. It is very easy to fall and get injured when squatting down to adjust the device. Moreover, maintaining a squatting position for a long time will increase the burden on the body and cause discomfort such as numbness in the legs and soreness in the lower back. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide an elevator maintenance testing device to solve the technical problem that traditional testing devices require staff to frequently squat down inside the running elevator for debugging. Due to the shaking and swaying of the elevator, it is difficult to maintain stability, which can easily lead to falls and injuries. Furthermore, maintaining a squatting posture for a long time increases the burden on the body and causes limb discomfort, which seriously affects the safety, efficiency and accuracy of the testing operation.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an elevator maintenance testing device, comprising a testing device, the testing device comprising a main body, a fixing mechanism provided on the back of the main body, the fixing mechanism comprising a mounting base, a rotating shaft provided on the inner side of the mounting base, and a fixing bolt provided on one side of the mounting base, the fixing bolt being used to fix the mounting base and the bearing;
[0006] A negative pressure suction cup seat is mounted on the rotating shaft via a connector. A negative pressure suction cup pad is provided on the outer surface of the negative pressure suction cup seat. An air pipe interface is provided at the bottom of the negative pressure suction cup seat, and a flexible hose is screwed onto the air pipe interface. The other end of the flexible hose is connected to an external air pump.
[0007] By adopting the above technical solutions, the fixing mechanism can be adjusted at multiple angles through the rotating shaft to adapt to different car structures; the negative pressure suction cup seat works with the external air pump to achieve quick and seamless installation and disassembly, improving maintenance efficiency.
[0008] Furthermore, the main body of the fixing mechanism is made of engineering plastic, and the fixing mechanism is used to fix the main body to the inner wall of the elevator car.
[0009] By adopting the above technical solutions, engineering plastic materials combine lightweight and high strength, making them suitable for thin-walled car structures; their antistatic and corrosion-resistant properties reduce interference from the hoistway environment and extend equipment life.
[0010] Furthermore, the surface of the main body is provided with a granular surface, which is used to increase the friction with the hand.
[0011] By adopting the above technical solutions, the granular surface increases hand friction to prevent the device from slipping; the hydrophobic properties accelerate the diversion of sweat and avoid accidental touches on the touch panel.
[0012] Furthermore, a touch panel is provided on the outer surface of the main body, and a plurality of first buttons are provided on the upper side of one side of the touch panel, and a sound outlet is provided below the first buttons.
[0013] By adopting the above technical solution, the touch panel and the first button are integrated, simplifying the operation process; the sound outlet provides real-time voice feedback, improving detection efficiency.
[0014] Furthermore, two USB ports are provided on the lower side of one side of the main body, and a second button is provided above the USB ports. The second button is used to start the detection device.
[0015] By adopting the above technical solution, the USB interface supports data transmission and power supply, and the second button enables one-click start, simplifying the operation logic.
[0016] Furthermore, the main body is generally rectangular in shape, and a protective film is adhered to the outer surface of the touch panel.
[0017] By adopting the above technical solutions, the rectangular structure is adapted to the car space layout; the protective film protects the touch panel and extends its service life.
[0018] In summary, the present invention has the following main advantages:
[0019] This utility model, through the setting of a fixing mechanism, mounting base, rotating shaft, fixing bolts, negative pressure suction cup base, negative pressure suction cup pad, and air pipe interface, allows the mounting base and rotating shaft to ensure that the operator can easily adjust the installation direction of the main body according to the car space, testing needs, and ease of operation, thus improving the comfort of the instrument during use. The fixing bolts can securely lock the mounting base and rotating shaft, ensuring that the testing device does not shift during elevator operation. The negative pressure suction cup base, negative pressure suction cup pad, and air pipe interface constitute a convenient and safe adsorption fixing structure, which can be installed according to the user's height requirements to improve the comfort of use. At the same time, installation does not require drilling, disassembly is damage-free, and it can be reused, reducing the cost of use. The strong adsorption force ensures that the device is stably fixed in complex operating environments for testing elevator operation.
[0020] This invention features a granular surface that effectively resists the risk of slippage caused by sweat, oil, and elevator vibration, ensuring operational safety and stability. Its anti-slip properties also reduce the probability of accidental touches on the touch panel. Furthermore, the micro-convex structure of the surface conforms to the curve of the palm, relieving hand fatigue during long-term work by dispersing pressure. It enhances functionality while also ensuring grip comfort, demonstrating targeted optimization for actual user needs. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example 1
[0027] An elevator maintenance testing device, such as Figure 1-4 As shown, the device includes a detection device 1, which comprises a main body 101. A fixing mechanism 2 is provided on the back of the main body 101. The fixing mechanism 2 includes a mounting base 201. A rotating shaft 202 is provided on the inner side of the mounting base 201. A fixing bolt 203 is provided on one side of the mounting base 201, and the fixing bolt 203 is used to fix the mounting base 201 and the rotating shaft 202. A negative pressure suction cup seat 204 is mounted on the rotating shaft 202 through a connector. A negative pressure suction cup pad 205 is provided on the outer surface of the negative pressure suction cup seat 204. An air pipe interface 20 is provided at the bottom of the negative pressure suction cup seat 204. 6. A flexible hose is screwed onto the air pipe interface 206, and the other end of the hose is connected to an external air pump. The rotating shaft 202 of the fixing mechanism 2 supports 360° horizontal rotation and ±45° vertical pitch adjustment, which can flexibly deal with uneven inner walls of the car or the position of the inspection port, ensuring that the detection device 1 is always in the best operating angle. The combination of the negative pressure suction cup seat 204 and the negative pressure suction cup pad 205 achieves traceless fixation through vacuum adsorption, avoiding damage to the aesthetics and structural integrity of the car caused by bolt drilling or adhesive residue. At the same time, it supports quick disassembly and assembly with one hand, which significantly improves maintenance efficiency.
[0028] See Figure 3 , Figure 4 The main body of the fixing mechanism 2 is made of engineering plastic. The fixing mechanism 2 is used to fix the main body 101 to the inner wall of the elevator car. The engineering plastic material ensures the structural strength of the fixing mechanism 2 while significantly reducing the weight of the device, avoiding deformation of the car wall or paint peeling due to long-term suspension. Its anti-static properties can effectively reduce dust adsorption in the shaft and prevent the rotating shaft 202 from being stuck due to particulate matter. Its corrosion resistance enables it to adapt to complex working conditions such as elevator oil stains and cleaning agents, reducing component aging caused by chemical corrosion and reducing maintenance costs. Example 2
[0029] See Figure 1 , Figure 2 The surface of the main body 101 is provided with a textured surface 107, which is used to increase the friction between the hand and the device. The textured surface 107 has a micron-level raised texture design, which significantly increases the friction between the hand and the device. It can still provide reliable grip in wet or oily environments and prevent the device from falling due to slipping. Its hydrophobic properties can quickly wick away sweat or cleaning liquids and prevent liquids from seeping into the touch panel 102, which may cause accidental touches or short circuits, thus ensuring operational safety. In addition, the elastic material of the textured surface 107 can distribute hand pressure and improve the comfort of holding it for a long time.
[0030] See Figure 1 , Figure 4The outer surface of the main body 101 is provided with a touch panel 102. Multiple first buttons 104 are provided on the upper side of one side of the touch panel 102. A sound outlet 103 is provided below the first buttons 104. The integrated design of the touch panel 102 and the first buttons 104 allows the testing personnel to complete high-frequency operations such as parameter setting and mode switching while holding the device with one hand, reducing the number of operation steps. The sound outlet 103 plays test data such as voltage, current values and fault alarm information in real time through a built-in speaker, avoiding operation interruption caused by looking down at the screen and improving testing efficiency. The sensitive response characteristics of the touch panel 102 ensure that the command is executed immediately and avoid misjudgment caused by delay.
[0031] See Figure 1 , Figure 2 Two USB ports 105 are located on the lower side of the main body 101. A second button 106 is located above the USB ports 105. The second button 106 is used to start the detection device 1. The USB ports 105 support the export of detection data, software upgrades, and power supply for external devices, meeting the needs of multiple scenarios such as connecting a USB flash drive to export logs and connecting a printer to output reports. The second button 106 adopts a physical press design and directly triggers the main control module through an independent circuit, avoiding startup failure caused by the touch panel 102 freezing. Its recessed structure can prevent accidental touch, and the fluorescent coating on the surface facilitates operation at night, significantly improving ease of use.
[0032] See Figure 3 , Figure 4 The main body 101 has a rectangular structure, and a protective film is adhered to the outer surface of the touch panel 102. The rectangular structure of the main body 101 is highly compatible with the planar features of the inner wall of the car, reducing space occupation. Its right-angled edge design can fit the corners of the car to avoid equipment displacement due to collision. The protective film adhered to the outer surface of the touch panel 102 uses a high-hardness, fingerprint-resistant coating, which can effectively resist scratches, oil stains and acid and alkali corrosion. It also supports electrostatic adsorption for traceless adhesion, which is convenient for future replacement. The rounded edge treatment of the protective film can prevent curling and further improve the reliability of protection.
[0033] The implementation principle of this embodiment is as follows: through the axial rotation structure of the rotating shaft 202 and the mounting base 201 in the fixing mechanism 2, and with the locking adjustment function of the fixing bolt 203, the main body 101 of the detection device can be freely positioned at multiple angles on the inner wall of the elevator car, so as to meet the spatial layout and detection angle requirements of different models of cars, and improve installation comfort and adaptability.
[0034] Utilizing the vacuum adsorption characteristics of the negative pressure suction cup seat 204 and the negative pressure suction cup pad 205, an external air pump is connected through the air pipe interface 206 to achieve rapid and non-destructive installation. After the test is completed, the air pump is turned off to release the negative pressure and complete the disassembly. The entire process requires no tools and leaves no residual damage, taking into account both efficient operation and equipment reusability. The surface of the main body 101 has a particle surface 107 to enhance the anti-slip performance of the handheld device and ensure operational stability.
