Description

Technical Field

[0001] This utility model relates to the field of work platform device technology, and in particular to a safety device and a work platform. Background Technology

[0002] When using aerial work platforms, the platform is a crucial structure for lifting personnel and providing safety protection. With the continuous improvement of laws and regulations in the aerial work industry, and considering the personal safety of workers, the state has introduced new requirements for aerial work platforms: all operations of the platform must immediately stop if a worker is crushed during operation to prevent further injury. To meet national regulations, various anti-crushing devices have been added to equipment involving aerial work platforms. Specifically, Chinese patent CN216997558U discloses an aerial work platform and a boom lift with the platform. While the boom lift provides some protection for workers, this protective structure must be pre-installed on the boom lift, making it inconvenient to install and remove, and it is not compatible with other work platforms.

[0003] Therefore, the shortcomings of existing technologies are that existing protective devices cannot be adapted to some older equipment, and many pieces of equipment in good working order will be forced to be taken offline or stopped from use because they cannot meet new regulatory requirements, thus causing a certain waste of resources.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example 1

[0029] Reference Figures 1 to 6 As shown, this utility model discloses a safety device applied to a work platform 10 to prevent workers from being crushed.

[0030] The safety device includes an installation unit, which includes a first mounting frame 1 and a second mounting frame 2, the first mounting frame 1 and the second mounting frame 2 being detachably assembled to the work platform 10.

[0031] The first mounting bracket 1 is provided with a placement component 11.

[0032] The safety device also includes a sensing unit, which includes a sensor 3 and a sensing rope assembly 4. The sensor 3 is disposed on the placement assembly 11.

[0033] Specifically, the sensing rope assembly 4 includes a body 40 and a connector 41. One end of the body 40 is detachably connected to the placement assembly 11 via the connector 41, and the other end of the body 40 is connected to the second mounting bracket 2. The sensor can detect whether the connector 41 is located within the placement assembly 11.

[0034] In detail, the safety device also includes a control unit, which is connected to the sensing unit. The control unit receives the sensing signal from the sensing unit and outputs a control signal to the work platform to control the operation of the work platform.

[0035] Under normal conditions, the sensing rope assembly 4 remains taut, and both ends of the body are connected to the first mounting bracket 1 and the second mounting bracket 2 respectively. At this time, the connector 41 is housed in the placement assembly 11, and the sensor 3 can detect the presence of the connector 41, thus being in a triggered state, and the work platform can work normally.

[0036] In the event of an emergency, if the worker is squeezed, their body will press against the sensing rope assembly 4, causing the connector 41 to detach from the placement assembly 11. At this time, the sensor 3 will no longer be in the triggered state. After receiving the signal from the sensor 3, the control unit will immediately output a control signal to the control system to control the entire machine (including the work platform) to stop moving, so as to avoid further injury to the worker.

[0037] Therefore, this utility model protects a safety device mounted on a work platform. The device includes an installation unit, a sensing unit, and a control unit. The installation unit comprises a first mounting bracket and a second mounting bracket, allowing for detachable installation on various work platforms. The sensing unit, through the cooperation of a sensing rope assembly and sensors, monitors whether the worker is being squeezed, preventing squeezing and further injury during high-altitude work. This utility model provides excellent anti-squeezing protection for workers while also accommodating different types of work platforms. It is adaptable to various equipment, easy to install, and widely applicable. Upgrading older equipment is also very convenient. The device determines whether the worker is being squeezed by detecting the tautness of the sensing rope; the judgment process is direct and efficient. Once the worker is out of danger, the sensing rope is placed into the corresponding placement assembly to restore the machine's operation. Disassembly is convenient, and interchangeability is good.

[0038] In a preferred embodiment, the placement assembly 11 includes a placement block 110, which has a groove with its opening 1101 facing downwards. The connector 41 can be engaged within the groove, allowing it to disengage from the groove under the pull of the body 40. Additionally, the placement block 110 has a mounting hole 1100 for assembling the sensor, which communicates with the groove.

[0039] In detail, the groove includes a connecting portion 1102 and a receiving portion 1103, with the connecting portion 1102 located between the opening 1101 and the receiving portion 1103; in the horizontal direction, the width of the connecting portion 1102 is smaller than the width of the receiving portion 1103. This configuration allows the connector 41 to be confined within the groove, providing a certain degree of stability and preventing it from detaching due to vibration, thereby effectively avoiding misjudgment.

[0040] In a preferred embodiment, the receiving portion 1103 is shaped to match the connector 41.

[0041] To facilitate reinstallation of the connector 41 after use and improve ease of use, the edge of the opening 1101 of the groove is chamfered.

[0042] In a preferred embodiment, the placement component 11 may also be made of a magnetic material, the connector 41 may be made of a magnetic material, and the placement block and the connector may attract each other.

[0043] The sensing rope assembly 4 also includes a threaded tail 42, which is screwed and fixed to the second mounting base 2.

[0044] The placement block 110 is mounted to the first mounting bracket 1 by fasteners, and the placement block 110 is made of aluminum alloy. The fasteners include, but are not limited to, bolts.

[0045] In a preferred embodiment, the first mounting bracket 1 includes a first connecting pipe 12, a first connecting plate 13, a second connecting plate 14, a first mounting plate 15, and a first mounting block 16. The two ends of the first connecting pipe 12 are bent toward the same side to form a first bent portion 121 and a second bent portion 122.

[0046] Specifically, the first connecting plate 13 is connected to the first bent portion 121, and the second connecting plate 14 is connected to the second bent portion 122; the first connecting plate 13 is movably connected to the working platform 10 through a connector 130, specifically, the connector 130 is a U-bolt, so that the first connecting plate 13 can be rotatably connected to the working platform 10.

[0047] The second connecting plate 14 is detachably connected to the first mounting block 16. The first mounting block 16 is provided with a mounting groove that can match the connecting rod of the work platform, so that the second connecting plate 14 is detachably connected to the work platform 10. The first mounting plate 15 is connected to the first connecting pipe 12, and the placement assembly 11 is assembled to the first mounting plate 15 by bolts.

[0048] Therefore, for aerial work platforms of different sizes from different manufacturers, the safety device only needs to be customized with one part to achieve compatible installation.

[0049] The structure of the second mounting bracket 2 is the same as that of the first mounting bracket 1, and the second mounting bracket 2 is symmetrically arranged with the first mounting bracket 1.

[0050] In a preferred embodiment, the sensor 3 includes, but is not limited to, a proximity switch.

[0051] The first mounting bracket 1 is also equipped with an indicator light 17, which is communicatively connected to the control unit. Preferably, the indicator light 17 is a strobe light, and the first connecting pipe 12 has a mounting port 120. The indicator light 17 is mounted to the first connecting pipe 12 through the mounting port 120, indicating to the ground and platform personnel that the machine is in normal working condition at a certain flashing frequency. When an accident causes the machine to stop, it indicates that the machine or personnel have malfunctioned at a different flashing frequency. Example 2

[0052] This utility model also discloses a working platform, combined with Figure 6 As shown, the work platform is equipped with a safety device as described in Embodiment 1.
