Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of crane voice alarm equipment, and in particular to an alarm device for crane supports. Background Technology
[0002] Cranes, as heavy machinery, play a vital role in logistics, construction, and many other industrial sectors. They are typically used to move and lift heavy objects to accomplish a variety of complex tasks. However, due to their generally large size, cranes often struggle to monitor and perceive their surroundings in real time during operation. This limitation leads to a common problem: personnel may inadvertently enter the work area without the operator noticing the potential danger. Modern cranes equipped with voice feedback systems can provide timely voice prompts and warnings to operators upon detecting abnormalities, and also alert those around the equipment in real time to the operation of the crane. Utility Model Content
[0003] In view of the shortcomings of the existing technology, this utility model provides an alarm device for crane support, which solves the problem that in the work area, personnel may inadvertently enter, and the operator may not be able to detect this potential danger in time.
[0004] According to an embodiment of the present invention, an alarm device for a crane support includes a sensing alarm mechanism that is movably coupled to the crane outrigger via a movable adjustment mechanism. The sensing alarm mechanism can adjust its position with the movable adjustment mechanism. The sensing alarm mechanism includes a movable positioning component that cooperates with the movable adjustment mechanism, and the movable positioning component can fix the position of the sensing alarm mechanism.
[0005] Preferably, the movable adjustment mechanism includes multiple vertical slides mounted on the crane outriggers and a horizontal support arranged around the crane outriggers and fixedly connected to the vertical slides. The sensing alarm mechanism also includes a housing, a radar identifier, a voice prompt, an alarm light, and a controller mounted on the housing. The movable positioning component is fixed to the housing and cooperates with the horizontal support. The radar identifier, the voice prompt, the alarm light, and the controller are electrically connected.
[0006] More preferably, the vertical slide is connected to the crane leg via a movable component, the movable component including a linear guide rail vertically and fixedly mounted on the crane leg, and a linear slider cooperating with the linear guide rail, the vertical slide being fixed on the linear slider.
[0007] More preferably, the horizontal support includes a support plate detachably connected to the vertical slide, and a plurality of positioning holes disposed on the support plate and evenly distributed in the horizontal direction, wherein the movable positioning component is detachably connected to the positioning holes.
[0008] More preferably, the positioning holes are provided in two sets and distributed in the vertical direction. The movable positioning component includes a movable frame fixedly connected to the box body and having an n-shaped structure, and a positioning bolt. The movable frame has two sets of screw holes distributed in the vertical direction on the side away from the box body. The positioning bolt cooperates with the screw holes and can extend into the positioning holes.
[0009] More preferably, the housing also includes a wireless signal transmission module electrically connected to the controller.
[0010] More preferably, the radar identifier is fixed to the side of the housing away from the horizontal support.
[0011] In a further preferred embodiment, the alarm light is fixed to the top of the box body, and the voice prompt device includes a broadcaster and a rotating base rotatably connected to the broadcaster. The rotating base is rotatably connected to the box body, the broadcaster's rotation axis is horizontal, and the rotating base's rotation axis is vertical.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] Warnings from the voice broadcast device can effectively alert personnel to the dangers of the crane operating area, thereby reducing the risk of accidental intrusion and ensuring personnel safety. It can also monitor the operating area in real time, issuing an immediate warning if anyone approaches, ensuring timely response and accident prevention. Voice broadcasts are more intuitive and easier to understand than traditional warning signs or signal lights, especially for personnel unfamiliar with the operating area rules, allowing them to quickly grasp the dangers of the current area. The sensor alarm mechanism can be adjusted according to the crane's working environment, making it more widely applicable. Attached Figure Description

[0020] This utility model provides an embodiment, such as Figure 1 , Figure 2 , Figure 3 As shown, an alarm device for a crane support includes a movable adjustment mechanism and a sensing alarm mechanism 3. The movable adjustment mechanism includes multiple vertical slides 1 movably mounted on the crane legs and a horizontal support 2 arranged around the crane legs and fixedly connected to the vertical slides 1. The sensing alarm mechanism 3 is movably connected to the horizontal support 2. In this embodiment, the crane has four vertical legs. The sensing alarm mechanism 3 includes a housing 310, a movable positioning component 320 fixed on the housing 310 and cooperating with the horizontal support 2, a radar identifier 301, a voice prompt 330, an alarm light 302, and a controller 303 mounted on the housing 310. The radar identifier 301, the voice prompt 330, the alarm light 302, and the controller 303 are electrically connected.
[0021] When the crane is in operation, the radar identifier 301 can detect personnel in the operating area and warn and remind personnel near the crane's working area through the voice prompt 330 and the alarm light 302 to prevent personnel from accidentally entering the dangerous area.
[0022] After the crane moves, the height of the sensing alarm mechanism 3 can be adjusted by the vertical slide 1 according to the movement route and location of the surrounding people, and the position of the radar identifier 301 in the horizontal plane can be adjusted by the active positioning component 320, so as to adapt to the sensing prompt work in different environments.
[0023] Specifically, such as Figure 1As shown, the vertical slide 1 is connected to the crane legs via a moving assembly 110. The moving assembly 110 includes a linear guide rail 111 vertically and fixedly mounted on the crane legs, and a linear slider 112 cooperating with the linear guide rail 111.
