Description

Technical Field

[0001] This utility model relates to the field of crane safety detection technology, specifically to a single-girder crane anti-derailment detection device. Background Technology

[0002] Single-girder cranes typically run along fixed tracks. If a derailment occurs during the lifting of goods, the consequences can be extremely serious. Derailment can damage the crane's structure, rendering it unable to work properly and requiring significant time and money for repair or replacement. More importantly, the goods being lifted by the crane may fall during a derailment, causing serious damage to the equipment and facilities below, and potentially resulting in injuries or fatalities. This can lead to huge economic losses for the company and a negative social impact.

[0003] Currently, most derailment detection devices equipped on single-girder cranes only issue alarm signals after a derailment accident has occurred. This post-accident alarm method cannot provide effective early warning before an accident happens, making it difficult for operators to take timely measures to prevent the accident from happening, thus making losses unavoidable. Therefore, there is an urgent need for a single-girder crane derailment detection device to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this utility model is to provide a single-girder crane anti-derailment detection device, which has the advantages of good detection effect and convenient adjustment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a single-girder crane anti-derailment detection device, comprising a single-girder crane body, a track body, and adjustable detection and early warning components. The track body slides on both sides of the bottom of the single-girder crane body. The adjustable detection and early warning components are arranged on both sides of the single-girder crane body, and there are eight of them. Each adjustable detection and early warning component includes a fixed base, a moving rod, a first slide groove, a first slider, a first threaded rod, a handle, a slide bar, a pressure control sensor, a second slide groove, a spring, a second slider, a third slide groove, a third slider, and a through groove.

[0006] Furthermore, a pressure control sensor is fixedly installed in the inner cavity of the fixed base, and a second sliding groove is provided on both sides of the inner cavity of the fixed base, with a second slider slidably connected inside the second sliding groove.

[0007] Furthermore, a movable rod is fixedly installed on the side of the second slider that is relatively close to it, and a spring is fixedly installed in the inner cavity of the second slide groove on the side of the second slider that is relatively close to it. A through groove is opened inside the movable rod.

[0008] Furthermore, a sliding rod is provided inside the through groove, and a third sliding groove is provided inside the moving rod at the bottom of the through groove, and a third slider is slidably connected inside the third sliding groove.

[0009] Furthermore, the top of the third slider is fixedly connected to the bottom of the slide rod, and a first slide groove is provided inside the moving rod and at the top of the through groove.

[0010] Furthermore, a first slider is slidably connected inside the first groove, and a first threaded rod is rotatably connected inside the first slider via a thread.

[0011] Furthermore, a handle is provided on the side of the movable rod that is relatively far away from the handle, and the side of the first threaded rod that is relatively far away from the handle is fixedly connected to the side of the first threaded rod that is relatively close to the handle.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are: This utility model utilizes a single-girder crane body to lift heavy objects and a track body to limit the crane body's movement, preventing swaying during transport. An adjustable detection and warning component prevents derailment. The main function is to detect derailment, and by adjusting its sensitivity, derailment prevention is achieved. First, rotating the handle rotates the first threaded rod, causing the first slider to move the sliding rod and third slider outwards to a designated position. When deviation occurs, the sliding rod contacts the track body, causing the moving rod to move the second slider inwards, contacting a pressure control sensor. The pressure control sensor then stops the crane, preventing derailment. This design offers advantages such as good detection effectiveness and easy adjustment. It solves the problem that current derailment detection devices on some single-girder cranes mostly issue alarm signals after a derailment has occurred, failing to provide effective warnings beforehand and making it difficult for operators to take timely measures to prevent accidents, leading to unavoidable losses.

More specifically, by providing the handle 36, the first threaded rod 35 is rotated, so that the first slider 34 drives the slider 37 to move outward.

[0023] Working principle: Step 1: The single-girder crane body 1 is used to lift the heavy object. The single-girder crane body 1 is limited by the track body 2 to prevent it from shaking during movement. The adjustable detection and warning component 3 is used to prevent it from derailing. The main purpose is to detect derailment. When the sensitivity of the detection is adjusted, derailment is prevented. First, turn the handle 36. The handle 36 drives the first threaded rod 35 to rotate, so that the first slider 34 drives the slider 37 and the third slider 394 to move outward until they reach the designated position. Step 2: When a deviation occurs, the slide bar 37 contacts the track body 2, causing the moving rod 32 to drive the second slider 392 to move inward and contact the pressure control sensor 38. Under the action of the pressure control sensor 38, the single-girder crane body 1 stops working to prevent it from derailing. This has the advantages of good detection effect and convenient adjustment.
