Description

Technical Field

[0001] This application relates to the field of lifting platform structures, and more particularly to a liftable diffuse reflection light protection device. Background Technology

[0002] In industrial automated production, large equipment operation, and other work scenarios with high safety requirements, the collaborative operation of personnel and machinery is becoming increasingly frequent. However, because machinery often possesses significant kinetic energy and potential hazards during operation, effectively ensuring the safety of workers and preventing accidents caused by personnel accidentally entering dangerous areas has become a critical issue that urgently needs to be addressed.

[0003] Traditional safety measures typically employ fixed physical fences or guardrails to separate hazardous areas from areas of activity. However, this fixed protection method has many limitations. For example, it cannot flexibly adjust the protection range according to actual work needs. When equipment maintenance, debugging, or special operations are required, the fence needs to be frequently dismantled and reinstalled, which is not only cumbersome and inefficient, but may also introduce new safety hazards during the dismantling and installation process.

[0004] With the development of photoelectric detection technology, safety protection devices built using photoelectric sensors are gradually being applied. These devices detect whether objects are entering a hazardous area by emitting and receiving light signals, and can promptly issue alarms or trigger corresponding safety mechanisms when an anomaly is detected. However, most existing photoelectric safety protection devices have fixed structures, and their detection range and height cannot be adjusted according to different working environments and equipment requirements, making them difficult to adapt to complex and ever-changing real-world application scenarios. For example, in some work environments where equipment height needs to be frequently adjusted, fixed-height photoelectric detection devices may not always effectively cover hazardous areas, leading to safety loopholes.

[0005] Furthermore, in practical applications, the operating status and working environment of the equipment may change. For example, the equipment may tilt or the support platform may experience uneven stress. These situations may affect the normal operation of the safety protection device. Existing devices often lack corresponding monitoring and response mechanisms, making it impossible to detect and deal with these potential safety issues in a timely manner.

[0006] Therefore, in order to overcome the shortcomings of existing safety protection devices and improve the flexibility and reliability of safety protection, it is necessary to develop a new type of liftable diffuse reflection light protection device. This device can flexibly adjust the detection range and height according to actual needs, and at the same time has the function of monitoring equipment operating status and environmental changes, so as to better protect the safety of operators.

Detailed Implementation

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0036] Specifically, such as Figure 1 As shown in the embodiment of this application, a liftable diffuse reflection light protection device is provided. This device is mainly installed in the lifting device, and through this device, the operators in the lifting device can be effectively protected and given early warning.

[0037] The device mainly includes support columns 100 and detection components 200. In this application, four support columns 100 are provided, which are respectively located at the four corners of the support platform 300. The support platform 300 is set on the lifting platform 400, which can be vertically and linearly moved through the lifting platform 400.

[0038] On the support column 100, there are four detection components 200, and each of the four detection components 200 is set one-to-one with the support column 100. The detection components 200 mainly include a detection bracket 210 and a sensor 220. The detection bracket 210 is movably set on the support column 100, so that the detection bracket 210 can move vertically on the support and be fixed on the support column 100. At the same time, in this application, the detection bracket 210 is a long strip structure, and the detection bracket 210 is horizontally set on the support column 100.

[0039] A sensor 220 is installed horizontally on the detection bracket 210. The output end of the sensor 220 is set horizontally and corresponds to the detection bracket 210 on the adjacent support column 100, so that the output end of the detection component 200 can form a detection area, which can detect the range of human movement.

[0040] To facilitate the movement of the testing bracket 210 on the support column 100, a sliding groove 110 is provided on the support column 100. The sliding groove 110 is vertically arranged on the support column 100. The testing bracket 210 can be horizontally installed in the sliding groove 110. A first adjusting member 211 is provided on the testing bracket 210 at a position corresponding to the sliding groove 110, and a second adjusting member 111 is provided in the sliding groove 110 at a position corresponding to the first adjusting member 211. This allows the testing bracket 210 to be installed in the sliding groove 110 through the cooperation of the first adjusting member 211 and the second adjusting member 111, and the testing bracket 210 can move vertically in the sliding groove 110.

[0041] In this embodiment, the first adjusting member 211 is configured as a protrusion, and the second adjusting member 111 is configured as a fixing groove. There are two protrusions, which are respectively located on both sides of the corresponding sliding groove 110 direction of the detection bracket 210.

[0042] The second adjusting member 111 is configured as a fixing groove, the shape of which is the same as that of the protrusion. When the detection bracket 210 is set on the support column 100, the protrusion is located in the fixing groove, so that the detection bracket 210 is fixed on the support column 100.

[0043] To facilitate the installation of the testing bracket 210 on the support column 100, multiple fixing slots are provided on the support column 100. These multiple fixing slots are arranged vertically linearly and evenly on the support column 100, making it convenient to install the testing bracket 210 at any position in the vertical direction on the support column 100.

[0044] Since the sensor 220 is mounted on the detection bracket 210, when the sensor 220 emits light, the corresponding receiving device 230 needs to receive it to facilitate the formation of a circuit between the sensor 220 and the receiving device 230. When the optical path between the sensor 220 and the receiving device 230 is broken, the corresponding receiving device 230 will not receive the light, and it can be determined that the person has moved to the edge of the support platform 300 and is in danger.

[0045] In the above, the receiving device 230 is disposed on the detection component 200 at a position corresponding to the adjacent sensor 220, and the receiving device 230 is electrically connected to the adjacent sensor 220.

[0046] Based on the above structure, this application embodiment also provides a structure in which a rotating member 310 is provided. The rotating member 310 is located at the bottom of the support platform 300, so that the support platform 300 can rotate around the rotating member 310.

[0047] However, in the above structure, it is necessary to maintain the stability of the support platform 300. Pressure detection devices 320 are set at the bottom of both sides of the support platform 300. The detection end of the pressure detection device 320 is set to correspond to the position of the support platform 300. The pressure detection device 320 is set on the lifting platform 400 so that the support platform 300 is set horizontally through the pressure detection device 320.

[0048] In this embodiment, the pressure detection device 320 measures the pressure change of the support platform 300 on the pressure detection device 320. A pressure threshold is set in the pressure detection device 320, and an alarm device 120 is set on the support column 100. The alarm device 120 is electrically connected to the pressure sensor. When the pressure change is greater than the pressure threshold, the alarm device 120 will trigger an alarm to prevent accidents from occurring.

[0049] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
