Description

Technical Field

[0001] The utility model relates to the field of crane mechanical safety, in particular to an anti-tilt alarm device, which is suitable for anti-tilt safety early warning of engineering equipment such as lifting devices and cranes. Background Art

[0002] At present, during the operation and transportation of engineering equipment, if the equipment tilts and deviates from the safe angle range, it is easy to cause safety accidents. For example, commonly used large equipment such as crane equipment and cranes may tilt away from the center, endangering property and people's lives. In order to prevent the crane equipment from tilting, an angle inclinometer is usually installed in the crane control room. The angle inclinometer is provided with an indicator device for indicating the horizontal angle deflection. The structure is complex and it is not easy to control the start and alarm. Patent document with announcement number CN105374161A discloses a tilt alarm device, including a travel switch connected to a power supply, an alarm, and a micro-switch; the travel switch is composed of a support frame, a distance control cross bar, a tension spring, a windproof ring and a plumb line assembly. Its structure is relatively complex, not easy to install and control the switch, and is not suitable for use in engineering equipment. Summary of the Invention

[0003] The purpose of the utility model is to provide an anti-tilt alarm, which solves the problem that conventional angle tilt alarms have complex structures and are difficult to control switches. It has a simple structure and is suitable for easy installation in engineering equipment for use, providing reliable and sensitive safety warnings and increasing equipment safety.

[0004] The technical solution adopted by the utility model is: an anti-tilt alarm, including a wireless signal transmission module connected through an angle tilt switch. The technical key points are: the alarm switch circuit is formed by the angle tilt switch, the wireless signal transmission module, the power supply and the power switch in series, the angle tilt switch is a mercury switch, the mercury switch is tilted and arranged in a control room that turns synchronously with the lifting equipment boom, and the fixed electrode of the mercury switch is arranged at the high end position of the mercury switch and faces the front end direction of the boom.

[0005] The mercury switch is provided by connecting at least two mercury switches in series.

[0006] The mercury switch has an inclination angle of 5 to 35 degrees.

[0007] The advantages and positive effects of the present invention are as follows: since the angle tilt switch of the anti-tilt alarm device of the present invention utilizes a mercury switch, the mercury switch is set to an angled deflection to connect the fixed electrode of the mercury switch. By tilting the mercury switch in an operating room that rotates synchronously with the boom of the lifting equipment, and the fixed electrode of the mercury switch being positioned at the upper end of the mercury switch and facing the front end of the boom, the boom of the lifting equipment sinks due to overload, causing the operating room position to tilt toward the front end of the boom. This can drive the fixed electrode of the mercury switch downward, and the mercury conductor at the bottom end flows toward the fixed electrode, thereby connecting the mercury switch, closing the alarm circuit, and transmitting a control signal to the alarm receiving end, thereby activating the alarm function. The mercury switch is directional, and an alarm signal is only issued when the mercury switch sinks and deflects in the direction of the boom of the lifting equipment. At the same time, false alarms caused by vibration and deflection in other directions are avoided. Therefore, the structure is simple and convenient for installation and use on engineering equipment such as lifting equipment, providing reliable and sensitive safety warnings and increasing equipment safety.

[0014] according to Figures 1 to 4 The specific structure of the utility model is described in detail. Figure 1 and Figure 3As shown, a kind of anti-inclination alarm 100, including by angle inclination switch device, wireless signal transmitting module 120, power supply 130 and power switch 140 are connected by electric lead in series to form alarm switch circuit.The angle inclination switch device in it is mercury switch 110, using the mercury switch of sale, also called tilting switch, is a kind of circuit switch, its two leads are fixed to the lead of the cylindrical insulating shell outside, the two lead ends in insulating shell are fixed electrode 112, it is equipped with about one fifth mercury conductor 111, because of the relationship of gravity, mercury beads will flow to lower place in container, when the insulating shell occurs angular deflection, mercury conductor flows to fixed electrode 112, contact to two electrodes simultaneously, connect two leads, will close circuit, form conductive path.Switching circuit is all connected at this time, trigger alarm to send alarm signal.Mercury switch is arranged in the synchronous steering control room 2 of hoisting equipment boom 1, and the fixed electrode 112 of mercury switch 110 is arranged in the high end position where mercury switch is placed, and it is towards the front end direction of boom.Alarm switch circuit each component can be arranged in control box by base plate 150, can make anti-inclination alarm can move with boom and crane operating room synchronously.Wireless signal transmitting module 113 uses the wireless signal transmitting module of sale, also can use intelligent remote control switch, for example, the type of TAD-T80 intelligent remote control switch of Shenzhen Taoan Electronics Co., Ltd. is used as wireless signal transmitting module and matched wireless signal receiving module, and alarm control signal can be sent.

[0015] As further improvement, as shown in Figure 1 Mercury switch inclination angle a can be set to 5-35 degrees, and the inclination angle of mercury switch can be set according to the degree of danger caused by the inclination of the boom of the hoisting equipment, to achieve reliable and effective alarm.

[0016] As shown in Figure 4 As further improvement, the mercury switch of the anti-inclination alarm is provided with at least two mercury switches in series, for example, three mercury switches can be used in series, which can reduce false alarm of single mercury switch, and make the anti-inclination alarm more reliable.

[0017] As shown in Figure 1 And 2As shown, by setting the mercury switch in the control room synchronously steering with the crane boom, the fixed electrode of the mercury switch is arranged at the high end position of the mercury switch, and the mercury switch is towards the front end direction of the boom, at this time, the mercury conductor is at the bottom end of the insulating shell container. When the boom of the crane is tilted towards the front end direction of the boom due to the sinking of the front end of the boom caused by load overload, the fixed electrode of the mercury switch is driven to move downwards, the mercury conductor at the bottom end flows to the fixed electrode, and then the mercury switch is connected, the alarm circuit is closed and connected, the wireless signal transmitting module sends a control signal to the alarm receiving end, and the alarm effect is achieved. The mercury switch has directionality, and only sinking and deflection towards the boom of the crane can send an alarm signal, and false alarms caused by vibration deflection in other directions can also be avoided. Therefore, the structure is simple, convenient to install on engineering equipment such as cranes, provides reliable and sensitive safety warning, and increases the safety of the equipment.

[0018] In conclusion, the purposes of the present application are achieved.
