Description

Technical Field

[0001] This utility model relates to the field of security technology, specifically a height-adjustable police platform for security purposes. Background Technology

[0002] In the security field, police platforms are important duty facilities, and their functionality and flexibility directly affect the efficiency and safety of security work. Traditional police platforms usually have the following limitations: most platforms have a fixed duty height, making it difficult to adapt to the monitoring needs of different scenarios.

[0003] For example, in densely populated areas or areas with complex terrain, when police officers are on duty at a platform, the height cannot be adjusted. A platform with a fixed height may cause blind spots for police officers, making it impossible for them to grasp the overall situation in a timely manner and resulting in insufficient response capabilities to emergencies.

[0004] Meanwhile, some platforms lack adequate protective structures, such as guardrails and warning devices, posing a risk of falls for police officers on duty at heights. Furthermore, the warning signs on the platforms themselves are not obvious at night or in low-light conditions, which is not only detrimental to the safety of officers on duty, but also fails to effectively warn and deter passersby.

[0005] According to the description of a riot police duty booth published on the patent website (authorization announcement number: CN212359246U), the riot police duty booth includes "protective frame, duty booth" etc., to realize the duty work of security personnel.

[0006] Regarding the above description, the applicant believes the following issues exist:

[0007] This riot police duty booth utilizes protective frames and a booth structure to enable security personnel to perform their duties. However, this booth can only be used at a fixed height. When police officers are on duty inside the booth, the height cannot be adjusted. In densely populated areas or complex terrain, the fixed-height platform may lead to blind spots for police officers, making it impossible to grasp the overall situation in a timely manner and resulting in insufficient response capabilities to emergencies. Therefore, this duty booth needs to be improved. Utility Model Content

[0018] Compared with the prior art, this utility model provides a height-adjustable security police platform, which has the following beneficial effects:

[0019] 1. This height-adjustable security police platform, through its lifting mechanism, uses a servo motor to drive a threaded rod to rotate, causing a movable frame to slide along a first guide rod. As the movable frame moves, it causes the first support shaft to change angle around the first connecting frame, and also causes the second support shaft to rotate around the second connecting frame and the fixed shaft, changing its angle. During this rotation, a slider slides around the second guide rod. The linkage mechanism, composed of two symmetrically distributed first and second support shafts and connecting frames, enables the smooth lifting and lowering of the duty platform. This design allows police officers to flexibly adjust their duty height according to different security scenarios, effectively expanding their field of vision, promptly grasping surrounding dynamics, and improving their monitoring and handling capabilities for emergencies. A protective frame and railing are installed at the top of the duty platform, providing comprehensive protection for police officers, effectively preventing accidental falls and ensuring personal safety during duty. Warning lights on the front of the protective frame serve as a warning at night or in low-light conditions, reminding passersby to be careful, and also helping to identify the location of the police platform, enhancing its deterrent effect.

[0020] 2. This height-adjustable security police platform features a movable mechanism where hydraulic cylinders control the lifting and lowering of the casters. When the platform needs to be moved, the hydraulic cylinders extend, causing the mounting base to move and the casters to contact the ground, while the support platform detaches from the ground. Police officers can easily push the platform to the designated location. Upon reaching the destination, the hydraulic cylinders retract, the casters retract, and the support platform lands and is fixed in place, ensuring platform stability and facilitating rapid response to security needs in different areas, enabling flexible deployment.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] This utility model provides the following technical solution:

[0032] Example 1

[0033] Please see Figure 1-6 This utility model provides a technical solution: a liftable security police platform, including a load-bearing platform 1, a protective frame 2 fixedly connected to the top of the load-bearing platform 1, a lifting mechanism 3 provided on the top of the load-bearing platform 1, and a moving mechanism 4 provided on the top of the load-bearing platform 1.

[0034] The lifting mechanism 3 includes a base 31, which is fixedly connected to the top of the support platform 1. A servo motor 32 is fixedly connected to the rear side of the base 31. A threaded rod 37 is fixedly connected to the front side of the servo motor 32. A support plate 38 is rotatably connected to the front side of the threaded rod 37. A movable frame 39 is threadedly connected to the outer periphery of the threaded rod 37. A first guide rod 392 is slidably connected inside the movable frame 39. A first support shaft 391 is rotatably connected to the outer right side of the movable frame 39. A first connecting frame 394 is rotatably connected to the top end of the first support shaft 391.

[0035] A fixed shaft 393 is rotatably connected inside the first support shaft 391. A second support shaft 397 is rotatably connected to the periphery of the fixed shaft 393. A slider 396 is rotatably connected inside the top of the second support shaft 397. A second guide rod 395 is slidably connected inside the slider 396. A duty station 33 is fixedly connected to the periphery of the second guide rod 395. A second connecting frame 398 is rotatably connected inside the bottom of the second support shaft 397. A protective frame 34 is fixedly connected to the top of the duty station 33. A warning light 35 is fixedly connected to the front of the protective frame 34. A guardrail 36 is fixedly connected to the rear of the protective frame 34.

[0036] The threaded rod 37 is rotatably connected to the inside of the base 31, the support plate 38 is fixedly connected to the bottom of the base 31, and the first guide rod 392 is fixedly connected to the inside of the base 31, so as to ensure the stability of the moving frame 39 when it moves.

[0037] The first connecting frame 394 is fixedly connected to the inside of the duty table 33, the second connecting frame 398 is fixedly connected to the inside of the base 31, and the guardrail 36 is fixedly connected to the top of the duty table 33, so that the stability of the first support shaft 391 and the second support shaft 397 can be further guaranteed by the first connecting frame 394 and the second connecting frame 398.

[0038] Two sets of first support shaft 391, first guide rod 392, fixed shaft 393, first connecting frame 394, second guide rod 395, slider 396, second support shaft 397, and second connecting frame 398 are provided and symmetrically distributed on the left and right sides of the movable frame 39. By setting two sets, it is easy to ensure the stability of the lifting and lowering of the duty platform 33. Two sets of protective frames 2 are provided and symmetrically distributed on the left and right sides of the top of the load-bearing platform 1 and located on the left and right sides of the base 31, so that the protective frames 2 can protect the left and right sides of the base 31.

[0039] Example 2

[0040] Please see Figure 1-6Furthermore, based on Embodiment 1, the moving mechanism 4 further includes a mounting frame 41, which is fixedly connected to the top of the support platform 1. A hydraulic cylinder 43 is fixedly connected to the top of the mounting frame 41, and a mounting base 44 is fixedly connected to the bottom of the hydraulic cylinder 43. A caster wheel 45 is fixedly connected to the bottom of the mounting base 44, and a slide rod 42 is fixedly connected to the top of the mounting base 44. The mounting base 44 is slidably connected to the inside of the support platform 1, and the slide rod 42 is slidably connected to the inside of the mounting frame 41, so as to ensure the stability of the movement of the caster wheel 45 driven by the mounting base 44 through the slide rod 42.

[0041] In actual operation, when this device is used, and when the duty station 33 is needed during security operations, the hydraulic cylinder 43 is activated according to the security location. The hydraulic cylinder 43 extends, causing the mounting base 44 to move the casters 45. When the mounting base 44 moves, it will cause the sliding rod 42 to slide inside the mounting frame 41, so that the casters 45 contact the ground and the load-bearing platform 1 is lifted off the ground. Police officers can easily push the platform to the designated location. After reaching the destination, the hydraulic cylinder 43 retracts, the casters 45 retract, and the load-bearing platform 1 is fixed on the ground, ensuring the stability of the platform and facilitating rapid response to the security needs of different areas, thus achieving flexible deployment.

[0042] At this time, security personnel can carry out security work by standing on the top of the duty station 33. The top of the duty station 33 is equipped with a protective frame 34 and a guardrail 36 to provide all-round protection for police officers, effectively preventing accidental falls and ensuring personal safety during duty. The warning light 35 installed on the front of the protective frame 34 can serve as a warning at night or in low-light environments, reminding passers-by to pay attention to safety, and also helps to mark the location of the police platform and enhance deterrence.

[0043] When the height of the duty station 33 needs to be adjusted, the servo motor 32 drives the threaded rod 37 to rotate, causing the movable frame 39 to slide along the first guide rod 392. When the movable frame 39 moves, it causes the first support shaft 391 to change angle around the first connecting frame 394, and causes the second support shaft 397 to rotate and change angle around the second connecting frame 398 and the fixed shaft 393. During the rotation, it causes the slider 396 to slide around the second guide rod 395. The linkage mechanism composed of the two sets of symmetrically distributed first support shafts 391, second support shafts 397 and connecting frames realizes the smooth raising and lowering of the duty station 33, allowing police officers to flexibly adjust the duty height according to the needs of different security scenarios, effectively expand the field of vision, keep abreast of the surrounding dynamics, and improve the monitoring and handling capabilities of emergencies.

[0044] The protective frame 2 is symmetrically distributed on the left and right sides of the top of the support platform 1 and located on the left and right sides of the base 31. When the lifting component of the duty platform 33 is lifting, the protective frame 2 can protect the left and right sides of the lifting component, preventing the public or staff from accidentally touching it and improving safety.

[0045] The servo motor 32 used in this case is a Siemens SQM10.16502 servo motor 32 (which is waterproof and has a self-locking function);

[0046] Furthermore, during use, the two hydraulic cylinders 43 and the servo motor 32 need to be connected to the same PLC controller to ensure the coordinated and synchronous operation between the devices. The PLC controller is existing technology and is common knowledge that is essential for those skilled in the art, so it will not be described in detail in this case.

[0047] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
