Description

Technical Field

[0001] The invention relates to a detection and protection device of a climbing vehicle and a setting method thereof. Background Art

[0002] Aerial platforms are widely used in civil construction for aerial work. From top to bottom, they consist primarily of an operating platform, a lifting system, and a mobile platform. The primary hazard with aerial platforms comes from the hydraulic lifting scissor mechanism. When the equipment is in operation, personnel performing lifting operations from the operating platform create a blind spot in the area surrounding the scissor mechanism, preventing accurate visual control of the surrounding environment. This can easily lead to injuries such as being cut or crushed if someone enters during the descent.

[0003] To prevent such accidents, there are currently a variety of solutions from the two aspects of construction management and hardware monitoring. For example, when a aerial platform is performing lifting operations, there must be a safety supervisor standing on the ground or soft barriers must be used to completely wrap the scissors support components.

[0004] These measures can improve construction safety to a certain extent, but there are still problems:

[0005] 1. The effectiveness of management-based safety measures depends largely on the professional level and work attitude of the personnel. Compared with protective devices, personnel supervision has limited effect on the improvement of protection effect;

[0006] 2. The installation, disassembly and maintenance of soft fencing are relatively complicated, and many users do not choose to use this protective device. Summary of the Invention

[0007] The purpose of the present invention is to provide a detection and protection device for a climbing vehicle and a setting method thereof.

[0008] In order to solve the above problems, the present invention provides a detection and protection device for a climbing vehicle, comprising:

[0009] A climbing vehicle, which includes a mobile trolley, a lifting system and an operating platform connected in sequence from bottom to top;

[0010] Ultrasonic rangefinders are installed around the mobile car;

[0026] Furthermore, in the above method, a grating sensor is provided under the operating platform, comprising:

[0027] The grating sensor is arranged on the edge of the lower surface of the operating platform.

[0028] Compared with the existing technology, the present invention can prevent injury accidents caused by the operator's visual blind spots when the aerial platform is performing lifting operations. By using ultrasonic rangefinders and grating sensor equipment to monitor the working area of the lifting system such as the scissors support components, it can prevent personnel intrusion and cause safety accidents.

[0029] The present invention uses ultrasonic rangefinders and grating sensors to monitor the horizontal and vertical dimensions of aerial platforms. The types and arrangements of the monitoring instruments enable all-round detection of the aerial platform's high-level space, with no blind spots or dead angles.

[0033] The present invention is described in further detail below with reference to the accompanying drawings.

[0034] like Figures 1 to 3 As shown, the present invention provides a detection and protection device for a climbing vehicle, comprising:

[0035] The climbing vehicle comprises a mobile vehicle 3, a lifting system 2 and an operating platform 1 connected in sequence from bottom to top;

[0036] An ultrasonic rangefinder 4 is provided around the mobile vehicle 3;

[0037] The grating sensor 5 is arranged under the operating platform 1.

[0038] Here, the main components of the aerial platform are: a moving vehicle 3, a lifting system 2 and an operating platform 1 from bottom to top.

[0039] like Figure 2 As shown, the ultrasonic rangefinder can detect people within 3 meters and continuously issue an alarm once a person approaches.

[0040] The present invention can prevent injury accidents caused by the operator's visual blind spots when the aerial platform is performing lifting operations. By using ultrasonic rangefinders and grating sensor equipment to monitor the working area of the lifting system such as the scissors support components, it can prevent personnel intrusion and cause safety accidents.

[0041] Preferably, the lifting system 2 is a scissors support component.

[0042] The scissor brace is a crucial component of aerial platforms, particularly self-propelled aerial platforms. It's a cross-shaped support structure, resembling the cross of scissors, typically composed of metal rods (such as steel pipes). Two rods intersect in the middle and are secured to the main frame of the aerial platform using bolts, pins, and other fasteners. This cross-structure enhances the overall stability of the aerial platform.

[0043] The hydraulic cylinder of the scissors support component can realize its lifting and lowering functions. During the lowering process, the distance between the various rods of the scissors support will be reduced, just like the blade of scissors, which will cause harm to people who accidentally enter its area.

[0044] like Figure 3 As shown, during the descent of the operating platform 1, vertical monitoring of the space around the scissor bracing components is also required to prevent shear injuries caused by personnel extending their limbs from the scaffolding, windows, and openings. A grating sensor is placed under the operating platform 1. If a foreign object intrudes into the operating channel space, the platform stops the lifting movement and issues an alarm.

[0045] Preferably, the ultrasonic rangefinders 4 are arranged at equal intervals around the mobile vehicle 3 .

[0046] Preferably, the ultrasonic rangefinders 4 are arranged around the mobile vehicle 3 at an equal distance of 2 meters.

[0047] Preferably, the grating sensor 5 is arranged on the edge of the lower surface of the operating platform 1 .

[0048] Here, if Figure 3 As shown, during the descent of the operating platform 1, vertical monitoring of the space around the scissor bracing components is also required to prevent shear injuries caused by personnel extending their limbs from scaffolding, windows, and openings. A grating sensor is placed on the lower edge of the operating platform 1. If a foreign object intrudes into the operating channel space, the lifting movement is stopped and an alarm is issued.

[0049] According to another aspect of the present invention, there is also provided a method for setting a detection and protection device of a climbing vehicle, comprising:

[0050] Connect the mobile trolley, lifting system and operating platform in sequence from bottom to top to form a climbing vehicle;

[0051] An ultrasonic rangefinder is set up around the mobile car;

[0052] A grating sensor is set under the operating platform.

[0053] Furthermore, the above method further includes:

[0054] The lifting system is configured as a scissors support component.

[0055] Furthermore, in the above method, an ultrasonic rangefinder is arranged around the mobile vehicle, comprising:

[0056] The ultrasonic rangefinders are arranged at equal intervals around the mobile vehicle.

[0057] Furthermore, in the above method, the ultrasonic rangefinders are arranged at equal intervals around the mobile vehicle, comprising:

[0058] The ultrasonic rangefinders are arranged at equal intervals of 2 meters around the mobile cart.

[0059] Furthermore, in the above method, a grating sensor is provided under the operating platform, comprising:

[0060] The grating sensor is arranged on the edge of the lower surface of the operating platform.

[0061] In summary, the present invention uses ultrasonic rangefinders and grating sensors to monitor the horizontal and vertical dimensions of aerial platforms. The types and arrangements of the monitoring instruments enable all-round detection of the aerial platform's high-level space, without blind spots or dead angles. Uninterrupted monitoring can be performed throughout the aerial platform's use period, with high reliability. This solves the problem of personnel being injured by equipment due to blind spots in the area below when operating the platform. The method is economical and effective, and can improve the safe operation of aerial platforms during their lifting process. High reliability of the monitoring equipment can be achieved, and installation, disassembly, and maintenance are convenient, meeting these two requirements. The monitoring equipment of the present invention is highly reliable and produces accurate results. The ultrasonic rangefinder can achieve uninterrupted monitoring, helping operators to judge the working conditions. Real-time monitoring of dangerous areas of aerial platforms can be achieved, greatly reducing the probability of safety accidents.
