Description

Technical Field

[0001] This utility model relates to the field of infrared alarm device technology, and in particular to an assembly frame for an intrusion prevention infrared alarm device for ladder trucks. Background Technology

[0002] The elevator car anti-intrusion infrared alarm device assembly rack is a device specifically designed to ensure the safe operation of elevator cars (such as elevators) within a specific area. This device monitors the position and movement of the elevator car using infrared technology. Once the elevator car is detected to have exceeded the preset safety range, the alarm system will be triggered, reminding staff to take timely measures to prevent the elevator car from intruding into the dangerous area, thereby ensuring the safety of the construction site.

[0003] In existing technologies, the device is installed at critical locations where elevator cars may pass, such as elevator shafts and stairwells, to ensure that the infrared sensor can accurately detect the movement of the elevator car without affecting its normal operation. Once the elevator car is detected to be outside the safe range, the alarm system is immediately triggered. However, this device requires regular inspection, which necessitates disassembly. Disassembly using tools is cumbersome and inconvenient. Therefore, an improved elevator car intrusion prevention infrared alarm device mounting bracket is needed to solve these problems. Utility Model Content

[0004] To overcome the problem that the elevator car anti-intrusion infrared alarm device assembly rack needs to be inspected regularly when the device is in use, we need to disassemble the device for inspection. Disassembly requires the use of tools, which is quite troublesome and brings inconvenience to the disassembly and installation of the device.

[0005] The technical solution of this utility model is as follows: an assembly frame for an intrusion prevention infrared alarm device for a ladder truck, including a fixed mounting base, a connecting bracket, and an adjustment component. A connecting fixed base is provided at the bottom of the fixed mounting base. An assembly connecting frame is slidably connected inside the fixed mounting base. A supporting connecting plate is provided at the top of the assembly connecting frame. An infrared detection probe is provided at the top of the supporting connecting plate. An alarm device is provided at the top of the supporting connecting plate. The adjustment component is located at the top of the assembly connecting frame. A connecting bracket is fixedly connected at the bottom of the assembly connecting frame. A fixed mounting plate is fixedly connected inside the fixed mounting base. A rotating threaded rod is rotatably connected inside the fixed mounting plate. A pressing limiting block is threadedly connected inside the rotating threaded rod. A fixed limiting rod is fixedly connected between the fixed mounting plate and the fixed mounting base. The pressing limiting block is slidably connected to the outside of the fixed limiting rod. By rotating the rotating threaded rod and threading it with the pressing limiting block, the pressing limiting block is pushed to contact the connecting bracket to achieve fixation.

[0006] Preferably, there are two fixed limiting rods, and the two fixed limiting rods are symmetrically fixedly connected inside the fixed mounting base.

[0007] Preferably, the connecting card holder has a slot at the corresponding position of the compression limiting block, and the compression limiting block slides inside the slot.

[0008] Preferably, a first motor is installed inside the fixed mounting base, and a rotating connecting shaft is fixedly connected to the output end of the first motor. A first bevel gear is fixedly connected to the outside of the rotating connecting shaft, and a second bevel gear is fixedly connected to the inside of the rotating threaded rod. The second bevel gear is meshed with the outside of the first bevel gear.

[0009] Preferably, there are two second bevel gears, and the two second bevel gears are symmetrically meshed and connected to the outside of the first bevel gear.

[0010] Preferably, the adjusting assembly includes a second motor disposed inside the assembly connecting frame. The output end of the second motor is fixedly connected to a first rotating shaft. A first gear is fixedly connected to the outside of the first rotating shaft. An adjusting threaded rod is rotatably connected inside the assembly connecting frame. A second gear is fixedly connected to the outside of the adjusting threaded rod, meshing with the outside of the first gear. A threaded connecting sleeve is threadedly connected to the outside of the adjusting threaded rod, and the threaded connecting sleeve is fixedly connected to the bottom of the support connecting plate. A limit support sleeve is fixedly connected inside the assembly connecting frame, and a limit support rod is slidably connected inside the limit support sleeve. The positioning support rod is fixedly connected to the bottom of the support connecting plate. A return spring is fixedly connected between the positioning support rod and the positioning support cylinder. A third motor is installed at the bottom of the support connecting plate. A second rotating shaft is fixedly connected to the output end of the third motor. The second rotating shaft is rotatably connected inside the support connecting plate. A third gear is fixedly connected to the outside of the second rotating shaft. A rotating support rod is rotatably connected inside the support connecting plate. A fourth gear is fixedly connected to the outside of the rotating support rod. The fourth gear is meshed with the outside of the third gear. A rotating connecting disc is fixedly connected to the top of the rotating support rod. The rotating connecting disc is rotatably connected inside the support connecting plate.

[0011] Preferably, the limiting support cylinder has a groove at the corresponding position of the limiting support rod, and the limiting support rod slides inside the groove.

[0012] The beneficial effects of this utility model are as follows: Compared with the assembly frame that is inconvenient for installing and disassembling the intrusion-proof infrared alarm device, the rotation of the set rotating threaded rod, and the threaded connection between the rotating threaded rod and the compression limiting block, causes the compression limiting block to slide inside the fixed mounting base under the limitation of the fixed limiting rod. The compression limiting block is locked into the inside of the connecting card seat to limit its movement, thus realizing the installation and disassembly of the device. This allows the infrared alarm device to be disassembled and installed without the need for tools, bringing convenience to the disassembly and installation of the device, and effectively preventing the need for tools to disassemble the device, which would make disassembly more troublesome.

[0020] Please see Figure 1 - Figure 5This utility model provides an embodiment of an infrared alarm device assembly frame for an intrusion prevention system for a ladder truck, including a fixed mounting base 1, a connecting bracket 801, and an adjusting component. A connecting mounting base 2 is located at the bottom of the fixed mounting base 1, and an assembly connecting frame 3 is slidably connected inside the fixed mounting base 1. A supporting connecting plate 4 is located at the top of the assembly connecting frame 3, an infrared detection probe 5 is located at the top of the supporting connecting plate 4, and an alarm device 6 is located at the top of the supporting connecting plate 4. The adjusting component is located at the top of the assembly connecting frame 3, and a connecting component is fixedly connected to the bottom of the assembly connecting frame 3. The mounting base 801 has a fixed mounting plate 802 internally fixedly connected to it. A rotating threaded rod 806 is rotatably connected internally to the fixed mounting plate 802. A pressing limit block 808 is threadedly connected internally to the rotating threaded rod 806. A fixed limit rod 809 is fixedly connected between the fixed mounting plate 802 and the fixed mounting base 1. The pressing limit block 808 is slidably connected to the outside of the fixed limit rod 809. By rotating the rotating threaded rod 806 and threading it with the pressing limit block 808, the pressing limit block 808 is pushed into contact with the mounting base 801 to achieve a fixed connection. The system includes a connecting fixing seat 2 to fix the fixing mounting seat 1 to the required installation position, an infrared detection probe 5 to detect the elevator car, an alarm device 6 to alert the elevator car if it intrudes into the space, and a rotating threaded rod 806 that is threadedly connected to a compression limiting block 808 to cause the compression limiting block 808 to slide inside the fixing mounting seat 1 under the limitation of the fixing limiting rod 809. The compression limiting block 808 is then engaged with the connecting card seat 801. The component limits its movement. Two fixed limiting rods 809 are provided, and the two fixed limiting rods 809 are symmetrically fixedly connected inside the fixed mounting base 1. The two fixed limiting rods 809 make the compression limiting block 808 more stable when sliding. The connecting card seat 801 has a slot at the corresponding position of the compression limiting block 808. The compression limiting block 808 slides inside the slot. By using the slot opened in the connecting card seat 801 at the position of the compression limiting block 808, the compression limiting block 808 is engaged inside the slot, thus limiting the movement of the connecting card seat 801.

[0021] Please see Figure 2 - Figure 3In this embodiment, a first motor 803 is installed inside the fixed mounting base 1. A rotating connecting shaft 804 is fixedly connected to the output end of the first motor 803. A first bevel gear 805 is fixedly connected to the outside of the rotating connecting shaft 804. A second bevel gear 807 is fixedly connected to the inside of the rotating threaded rod 806. The second bevel gear 807 is meshed with the outside of the first bevel gear 805. The first motor 803 drives the rotating connecting shaft 804 to rotate inside the fixed mounting base 1. The rotation of the rotating connecting shaft 804 drives the first bevel gear 805 and the second bevel gear 807 to mesh and rotate. The rotation of the second bevel gear 807 drives the rotating threaded rod 806 to rotate. There are two second bevel gears 807, and the two second bevel gears 807 are symmetrically meshed with the outside of the first bevel gear 805. The two second bevel gears 807 enable the pressing limit block 808 to slide synchronously inside the fixed mounting base 1 through the threaded connection with the rotating threaded rod 806.

[0022] Please see Figure 4 - Figure 5In this embodiment, the adjustment component includes a second motor 901, which is disposed inside the assembly connecting frame 3. The output end of the second motor 901 is fixedly connected to a first rotating shaft 902. A first gear 903 is fixedly connected to the outside of the first rotating shaft 902. An adjusting threaded rod 904 is rotatably connected inside the assembly connecting frame 3. A second gear 905 is fixedly connected to the outside of the adjusting threaded rod 904. The second gear 905 meshes with the outside of the first gear 903. The external thread of the adjusting threaded rod 904... A threaded connecting sleeve 906 is connected and fixedly connected to the bottom of the supporting connecting plate 4. A limit support sleeve 907 is fixedly connected inside the assembly connecting frame 3. A limit support rod 908 is slidably connected inside the limit support sleeve 907 and fixedly connected to the bottom of the supporting connecting plate 4. A return spring 909 is fixedly connected between the limit support rod 908 and the limit support sleeve 907. A third motor 910 is provided at the bottom of the supporting connecting plate 4, and a second rotating shaft is fixedly connected to the output end of the third motor 910. 911, the second rotating shaft 911 is rotatably connected inside the support connecting plate 4. A third gear 912 is fixedly connected to the outside of the second rotating shaft 911. A rotating support rod 913 is rotatably connected inside the support connecting plate 4. A fourth gear 914 is fixedly connected to the outside of the rotating support rod 913, meshing with the outside of the third gear 912. A rotating connecting disc 915 is fixedly connected to the top of the rotating support rod 913, and the rotating connecting disc 915 is rotatably connected inside the support connecting plate 4. The second motor 911 is used to... 01 drives the first rotating shaft 902 to rotate, which in turn drives the second gear 905 to mesh with the first gear 903 and rotate. The rotation of the second gear 905 drives the adjusting threaded rod 904 to rotate inside the assembly connecting frame 3. The limiting support cylinder 907 has a groove at the corresponding position of the limiting support rod 908. The limiting support rod 908 slides inside the groove. The groove at the corresponding position of the limiting support rod 908 inside the limiting support cylinder 907 limits the limiting support rod 908 when it slides in the groove.

[0023] During operation, the rotation of the connecting shaft 804 drives the first bevel gear 805 and the second bevel gear 807 to mesh and rotate. The rotation of the second bevel gear 807 drives the rotating threaded rod 806 to rotate. The rotation of the rotating threaded rod 806, coupled with its threaded connection to the extrusion limiting block 808, causes the extrusion limiting block 808 to slide within the fixed mounting base 1 under the limitation of the fixed limiting rod 809. The extrusion limiting block 808 engages with the connecting bracket 801 to limit its movement, thus enabling the installation and disassembly of the equipment. The second motor 901 drives the first rotating shaft 902 to rotate, which in turn drives the second gear 905 to mesh and rotate with the first gear 903. The rotation of 905 drives the adjusting threaded rod 904 to rotate inside the assembly connecting frame 3. The height of the support connecting plate 4, which is threadedly connected to the threaded connecting cylinder 906 by the rotation of the adjusting threaded rod 904, is adjusted. When the support connecting plate 4 moves, it is limited by the sliding of the limiting support rod 908 inside the limiting support cylinder 907. The third motor 910 drives the second rotating shaft 911 to rotate inside the support connecting plate 4. The rotation of the second rotating shaft 911 drives the third gear 912 and the fourth gear 914 to mesh and rotate. The rotation of the fourth gear 914 drives the rotating support rod 913 to rotate. The rotation of the rotating support rod 913 drives the rotating connecting plate 915 to rotate inside the support connecting plate 4, thereby adjusting the angle of the infrared detection probe 5.

[0024] Through the above steps, the rotation of the set rotating threaded rod 806, and the threaded connection between the rotating threaded rod 806 and the compression limiting block 808, causes the compression limiting block 808 to slide inside the fixed mounting base 1 under the limitation of the fixed limiting rod 809. The compression limiting block 808 is engaged with the inside of the connecting card seat 801 to limit its movement, thereby realizing the installation and disassembly of the equipment. This solves the problem that when the elevator car anti-intrusion infrared alarm device assembly rack is used, we need to inspect it regularly. When inspecting the device, we need to disassemble it for inspection, which requires the use of tools and is quite troublesome, causing inconvenience to the disassembly and installation of the device.
