[0002] At present, engineering equipment in operation and transportation work, if it deviates from the horizontal direction, it is easy to cause safety accidents. For example, commonly used large equipment such as crane equipment and cranes may deviate from the center and tilt, 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 indicating the horizontal angle deflection. The structure is complex and it is not easy to control the start and alarm. The 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. It is not easy to control the switch, and the installation is cumbersome and complicated, which is not suitable for use in engineering equipment. Utility Model Content

[0003] The purpose of the utility model is to provide an angle tilt alarm, which solves the problem that the conventional angle tilt alarm has a complex structure and is difficult to control the switch. It has a simple structure and is suitable for convenient installation in engineering equipment, providing reliable early warning and increasing safety.

[0004] The technical solution adopted by the utility model is: an angle tilt alarm, including an alarm connected through an angle tilt switch, and the technical points are: the angle tilt switch includes an upright conductive cylinder with a conductive layer on the inner wall fixedly arranged in an outer shell and a trigger suspended on the central axis of the inner cavity of the conductive cylinder, the trigger is provided with a conductive outer skin, the conductive outer skin is connected to an electrode at one end of a power supply through a suspension wire, the conductive cylinder is connected to an electrode at the other end of the power supply through a button-type electric switch connected in series with the wire to form a switch circuit, the switch circuit is connected to the alarm, and the alarm is provided with a wireless signal transmission module.

[0005] A non-conductive traction rope is connected between the lower movable end of the switch button of the button-type electric switch and the trigger. The non-conductive traction rope is used to be in a relaxed state when the switch button is in an open position at a low position, and in a tightened state when the switch button is in a closed position at a high position.

[0006] A guide wheel for a non-conductive traction rope is arranged in the outer shell of the angle tilt switch.

[0007] The utility model has the advantages and positive effects that: since the angle tilt alarm of the utility model is provided with an upright conductive cylinder with a conductive layer on the inner wall and a trigger suspended in the inner cavity of the conductive cylinder, the trigger is provided with a conductive outer skin, the conductive outer skin is connected to the electrode at one end of the power supply through a suspension wire, and the conductive cylinder is connected to the electrode at the other end of the power supply through a push-type electric switch connected in series with the wire to form a switch circuit. When the push-button electric switch is not pressed to turn on, the switch circuit always remains disconnected, and the trigger droops naturally; when in use, the switch is connected by pressing the push-button electric switch. When the angle tilt alarm is tilted, the conductive cylinder is driven to tilt in the horizontal direction at the same time, and the conductive outer skin of the trigger contacts the conductive layer of the conductive cylinder, so that the switch circuit connected in series with the conductive cylinder, the trigger and the push-type electric switch is turned on, and the alarm is powered on and sends an alarm signal through a wireless signal transmission module. Therefore, it can be conveniently installed on cranes and crane engineering equipment, has a simple structure, and can conveniently and reliably control the use of the angle tilt alarm, and can timely and reliably send an alarm signal when tilting occurs, avoiding the crane tilt alarm system from sending an alarm signal by mistake, providing a reliable early warning, and increasing safety.

[0011] Explanation of serial numbers in the figure: 300 alarm, 301 conductive cylinder, 302 suspension wire, 303 trigger, 304 non-conductive traction rope, 305 push-button electric switch, 306 moving end under the switch button, 307 guide wheel, 308 outer shell, 309 tilt angle. DETAILED DESCRIPTION

[0012] according to Figure 1 and 2 The specific structure of the utility model is described in detail, and the implementation example Figure 1 and Figure 2As shown, an angle tilt alarm includes a vertical conductive cylinder 301 with a conductive layer on the inner wall fixedly arranged in an outer shell 308, a trigger 303 is suspended at the central axis position of the inner cavity of the conductive cylinder, the trigger is a counterweight block with a certain weight, the trigger is provided with a conductive outer skin, the conductive outer skin is connected to the electrode at one end of the power supply through a suspension wire 302, and the conductive cylinder 301 is connected to the electrode at the other end of the power supply through a button-type electric switch 305 connected in series with a wire to form a switch circuit, and the power supply can be a battery. The button-type electric switch 305 can use a conventional switch button with a spring, and by pressing the switch button, the lower movable end 306 of the switch button of the push rod is displaced and connected to a low position to form a switch connection state, and by pressing the switch button again, it bounces back to a high position to form a switch disconnection state. The switch circuit is connected to an alarm 300, and the alarm is provided with a wireless signal transmission module. After the switch circuit is connected, the alarm is triggered to send an alarm signal, and the signal receiving end of the engineering equipment control system receives the signal.

[0013] As a further improvement, a non-conductive traction rope 304 is connected between the lower movable end 306 of the switch button of the push-button electric switch 305 and the trigger 303. By utilizing the up and down displacement of the lower movable end of the switch button, the non-conductive traction rope 304 is in a relaxed state in the open position of the low position of the switch button, which allows the trigger to droop naturally and shake, and still droop naturally when the tilt alarm is tilted; the non-conductive traction rope 304 is in a taut state in the closed position of the high position of the switch button, which keeps the trigger from shaking. Even when the tilt alarm is tilted, the trigger is still taut and cannot contact the inner wall of the upright conductive cylinder, thereby increasing the safety of the tilt alarm and avoiding the false alarm signal. A guide wheel 307 for the non-conductive traction rope can also be provided in the outer shell of the angle tilt switch to ensure the effective traction of the guided non-conductive traction rope and facilitate the arrangement of the non-conductive traction rope, thereby reducing the occupancy of the public. Working process and principle: Figure 1 and Figure 2 As shown, the angle tilt alarm is fixed on engineering equipment, such as a crane body. When the angle tilt alarm is required to work, the button type electric switch 305 is pressed, and the button type electric switch is connected. When the crane body tilts, the conductive cylinder 301 tilts synchronously to form a tilt angle 309, and contacts the trigger that is still naturally drooping due to gravity. At this time, all the switch circuits are connected, triggering the alarm to send an alarm signal, and the wireless signal transmission module is used to send the alarm signal to the crane controller or the crane control system.

[0014] If a non-conductive traction rope 304 is used, when the tilt alarm of this angle needs to work, the push-button electric switch 305 is pressed, the push-button electric switch is connected, and the low and high positions of the movable end under the switch button are shifted up and down. The non-conductive traction rope is in a relaxed state in the open position of the low position of the switch button, which can make the trigger 303 droop naturally and shake. It still droops naturally when the tilt alarm tilts. When the crane body tilts, the conductive cylinder 301 tilts synchronously to form a tilt angle 309, and contacts the trigger that is still drooping naturally due to gravity. At this time, all switch circuits are connected, triggering the alarm to send an alarm signal; when the tilt alarm of this angle is not needed to work, the non-conductive traction rope is in a taut state in the closed position of the high position of the switch button, keeping the trigger from shaking. Even when the tilt alarm tilts, the trigger is still taut and cannot contact the inner wall of the upright conductive cylinder, thereby increasing the safety of the tilt alarm, avoiding the false alarm signal, and providing reliable early warning information to send an alarm signal.

[0015] In summary, the purpose of the utility model is achieved.
