Description

Technical Field

[0001] This utility model relates to the field of escalator technology, and in particular to an escalator tilting sensing device with an alarm mechanism. Background Technology

[0002] Elevators can be divided into escalators and hanging elevators according to their operation mode. They can transport people or goods to different floors, greatly saving manpower. Due to the building structure, escalators are often built at an angle. Escalators operate automatically and cannot transport goods. Pedestrians walk onto the steps and hold onto the handrails to maintain their balance.

[0003] To ensure the safety of escalators after installation, in addition to regular maintenance, it is also necessary to monitor the tilt angle of the escalator in real time to prevent it from tipping over. However, most of the previous sensing devices were specially customized for escalators and their structures are not easily moved or adjusted. If the sensing mechanism is too sensitive, even a slight vibration will trigger an alarm if there are too many people on the escalator.

[0004] Now, a novel escalator tilting detection device with an alarm mechanism is proposed to solve the above problems. Utility Model Content

[0005] To address the aforementioned technical problems, the purpose of this utility model is to propose an escalator overturning sensing device for an alarm mechanism, thereby solving the problem of false alarms in sensing devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An escalator tilting detection device with an alarm mechanism includes an escalator body at an angle to the ground. A base plate is disposed below the escalator body, flush with the ground. A vertical sleeve is disposed on the base plate, with a cavity at the upper part of the sleeve and a mating hole communicating with the cavity at the top of the sleeve. A support plate is disposed on the bottom surface of the escalator body, with a downwardly extending vertical rod on the support plate. A slide tube is disposed at the bottom of the vertical rod, with its lower part passing through the mating hole into the cavity. A mounting hole is disposed at the bottom of the slide tube. A guide rod is disposed at the bottom of the cavity, with a rubber sleeve fitted onto the guide rod and inserted into the mounting hole. A spring is fitted onto the slide tube, located between the vertical rod and the sleeve. Several pressure rods connected to the vertical rod are disposed on the outside of the slide tube, with a gravity sensor connected to the top surface of the sleeve located below each pressure rod.

[0008] Preferably, the substrate is provided with a base, the base is provided with a vertically upward lead screw, the lead screw is rotatably connected to the base, the bottom of the sleeve is provided with a connecting hole, the connecting hole is provided with an internal thread, the lead screw is helically connected to the connecting hole, the substrate is provided with a limiting rod parallel to the sleeve, and the sleeve is provided with a sleeve block that is vertically slidably connected to the limiting rod.

[0009] Preferably, the lead screw is provided with a worm gear coaxial with the lead screw, the worm gear is fixedly connected to the lead screw, a motor is provided on one side of the base, a worm is provided at the output end of the motor, and the worm gear is meshed with the worm.

[0010] Preferably, an alarm electrically connected to a gravity sensor is provided on one side of the sleeve.

[0011] Preferably, the support plate is provided with a rotating block, and the vertical rod is rotatably connected to the rotating block.

[0012] Preferably, the rotating block is provided with a plurality of threaded holes, which are distributed on a circumference with the rotation center of the vertical rod and the rotating block as the center. The vertical rod is provided with a positioning hole, and a fixing bolt passes through the positioning hole and is fastened to the threaded hole.

[0014] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0015] This utility model relates to an escalator tilting sensor with an alarm mechanism. It includes an escalator body at an angle to the ground, a base plate attached to the ground at the bottom of the escalator body, a vertical sleeve on the base plate, a cavity at the upper part of the sleeve, a support plate on the bottom surface of the escalator body, a vertical rod on the support plate, a slide tube at the bottom of the vertical rod, the lower part of the slide tube passing through a mating hole into the cavity, a mounting hole at the bottom of the slide tube, and a guide rod at the bottom of the cavity. A rubber sleeve is fitted onto the guide rod and inserted into the mounting hole. In the middle section, a spring is fitted onto the slide tube, and a pressure rod is installed on the outside of the slide tube. A gravity sensor is installed below the pressure rod. If the main body of the escalator tilts, the vertical rod will sink, and the bottom slide tube will increase the friction between itself and the guide rod with the rubber sleeve. If the pressure rod touches the gravity sensor, an alarm will sound to alert people in the vicinity. The spring's elasticity can prevent the pressure rod from being accidentally triggered by vibration, and prevent the alarm from being triggered by slight tilting due to increased passenger load. This makes the detection of the escalator's tilt angle more accurate and avoids false alarms. Attached Figure Description

[0025] As attached Figure 1 Appendix Figure 2The diagram shows an escalator tilting detection device with an alarm mechanism according to this utility model. It includes an escalator body 1 at an angle to the ground, a base plate 2 mounted below the escalator body 1 and flush with the ground, and a vertical sleeve 3 connected to the base plate 2. The upper part of the sleeve 3 has a cavity 31, and the top of the sleeve 3 has a mating hole communicating with the cavity 31. A support plate 4 is connected to the bottom surface of the escalator body 1, and a downwardly extending vertical rod 5 is mounted on the support plate 4. A sliding tube 6 is connected to the bottom of the vertical rod 5, as shown in the attached diagram. Figure 3 As shown, the lower part of the slide tube 6 passes through the mating hole and enters the cavity 31. The bottom of the slide tube 6 has a mounting hole. The bottom of the cavity 31 has an upwardly extending guide rod 7. A rubber sleeve 8 is fitted onto the guide rod 7 and inserted into the mounting hole. When the slide tube 6 and the guide rod 7 slide relative to each other, the inner and outer walls of the rubber sleeve 8 generate friction with the guide rod 7 and the slide tube 6, respectively. A spring 9 is fitted onto the slide tube 6. The spring 9 is located between the vertical rod 5 and the sleeve 3, and it does not contact the surface of the slide tube 6. Several pressure rods 10 connected to the vertical rod 5 are installed on the outside of the slide tube 6. A gravity sensor 11 connected to the top surface of the sleeve 3 is installed below the pressure rods 10. An alarm 18, which is electrically connected to the gravity sensor 11, is installed on one side of the sleeve 3. If the angle between the escalator body 1 and the ground changes, the vertical rod 5 sinks, and the slide tube 6 increases the friction between itself and the guide rod 7 by means of the rubber sleeve 8. When the pressure rod 10 contacts the gravity sensor 11, the alarm 18 sounds an alarm bell to warn the people around.

[0026] A base 12 is mounted on the base plate 2, and a vertically upward lead screw 13 is mounted on the base 12. The lead screw 13 is horizontally rotatably connected to the base 12. A connecting hole is opened at the bottom of the sleeve 3, and an internal thread is machined in the connecting hole. The lead screw 13 is screwed to the connecting hole. A limiting rod 14 parallel to the sleeve 3 is mounted on the base plate 2, and a sleeve block 32 vertically slidably connected to the limiting rod 14 is mounted on the sleeve 3. When the lead screw 13 rotates, it drives the sleeve 3 to move up and down along the limiting rod 14. In this embodiment, a worm gear 15 coaxial with the lead screw 13 is mounted on the lead screw 13. The worm gear 15 is fixedly connected to the lead screw 13. A motor 17 is mounted on one side of the base 12, and a worm gear 16 is mounted on the output end of the motor 17. The worm gear 15 and the worm gear 16 are meshed and connected so that the motor 17 drives the lead screw 13 to rotate, adjusting the height of the upper vertical rod 5, the rotating block 19, and the support plate 4, so that it can support the escalator body 1 at different angles.

[0027] The support plate 4 is fastened to the bottom surface of the escalator body 1 by bolts, as shown in the attached figure. Figure 4As shown, the support plate 4 has a rotating block 19, and the vertical rod 5 is rotatably connected to the rotating block 19. The rotating block 19 has several threaded holes 191 machined on it, distributed on a circumference centered on the rotation center of the vertical rod 5 and the rotating block 19. The vertical rod 5 has positioning holes, and a fixing bolt 20 passes through the positioning holes and is fastened to the threaded holes 191. Rotating the rotating block 19 allows each threaded hole 191 to pass through the positioning holes in sequence. After determining the angle of the support plate 7, the fixing bolt 20 is screwed in, allowing the fixing bolt 20 to connect with different threaded holes 191, enabling the support plate 4 to connect with the escalator body 1 at different angles. In this embodiment, the top of the vertical rod 5 has a groove, into which the rotating block 19 is inserted. The rotating block 19 has circular grooves 192 machined on it, and the threaded holes 191 are distributed on both sides of the rotating block 19. The fixing bolt 20 passes through the positioning holes on both sides and is fastened to the threaded holes 191, making the connection more stable and reliable.

[0028] During installation, first move the base plate 2 to the bottom of the escalator body, start the motor 17 to drive the worm gear 16, the worm gear 16 drives the worm wheel 15 that meshes with it to rotate, so that the lead screw 13 rotates synchronously. Under the restriction of the limit rod 14, the sleeve 3 moves up and down in the vertical direction. Adjust the height of the vertical rod 5, the rotating block 19 and the support plate 4, turn the rotating block 19 with the circular groove 192. As the rotating block 19 rotates, each threaded hole 191 passes through the positioning hole in sequence. After determining the angle of the support plate 4, screw in the fixing bolt 20 for reinforcement, lock the support plate 4, and install the support plate 4 on the lower surface of the escalator body with bolts. When the escalator body tilts, the vertical rod 5 immediately sinks, and the bottom slide tube 6 increases the friction between itself and the guide rod 7 with the rubber sleeve 8. If the pressure rod 10 touches the gravity sensor 11, the alarm 18 will sound an alarm bell to warn the surrounding personnel and also notify the staff to come for maintenance quickly. The elasticity of the spring 9 can prevent the pressure rod 10 from being accidentally touched due to vibration, and prevent the alarm from being triggered due to slight tilting caused by an increase in the number of passengers on the escalator.
