Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision reminders, and in particular to an intelligent anti-collision device for a crane. Background Art

[0002] Large gantry cranes are important production tools for shipyards, ports, and docks. They generally travel along fixed tracks with a track length of more than 100 meters. Some cranes are equipped with wheels at the bottom of the crane for easy movement. Generally speaking, whether it is track-type or wheel-type, the crane moves within the moving area. In recent years, the equipment density in factories has increased year by year. In the same area where cranes work, there are often multiple cranes or vehicles and personnel working at the same time. Their working spaces overlap with each other, which is prone to collisions and accidents. Therefore, a safe and reliable crane travel anti-collision protection system is needed.

[0003] At present, there is also an optical sensor light (ordinary light or laser) set at the end of the crane's walking mechanism to protect the crane from collision. The optical sensor usually requires a reflector. The monitoring area of ​​the optical sensor is a single point trigger, and there will be a blind spot. The existing solution is to increase the number to achieve overlapping of the detection area to ensure safe use. However, when installing the sensor, most of them are directly installed on the side of the crane with bolts. Once affected by vibration or wind, the reflector of the sensor will shift in angle. Due to its high position, it is very inconvenient to manually adjust the angle. Therefore, this technical solution is proposed for improvement. Utility Model Content

[0004] The utility model aims to overcome the shortcoming in the prior art that the optical sensor of the crane is inconvenient to adjust the monitoring angle after installation, and to provide an intelligent anti-collision device for the crane.

[0005] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: an intelligent anti-collision device for a crane, comprising a sensor body, an angle adjustment device is arranged on the back side of the sensor body, the angle adjustment device comprises a mounting seat connected to the sensor body, a support rod is hinged on the side of the mounting seat, a support seat connected to the crane is arranged at the other end of the support rod, an adjustment rod for changing the detection angle of the sensor body is arranged between the support seat and the mounting seat, and one end of the adjustment rod is connected to the mounting seat through a spherical head.

[0006] Furthermore, a protective shell is arranged on the outer side of the sensor body, the upper part of the protective shell protrudes outward, and a fan for discharging air downward is arranged on the upper part of the protective shell.

[0007] Furthermore, the support rod is hinged to the support seat, the adjustment rod is arranged above the support rod, the adjustment rod is a screw rod, a fixing plate is arranged on the upper part of the support seat, a strip-shaped adjustment hole is arranged in the middle position of the fixing plate, a sleeve is hinged inside the adjustment hole, and one end of the adjustment rod is screwed inside the sleeve.

[0008] Furthermore, a motor is provided on one side of the fixing plate, and the motor is screwed to the adjusting rod via a connecting seat.

[0009] Furthermore, connecting springs are provided at the bottom of the mounting seat and the supporting seat.

[0010] Furthermore, the side of the mounting seat is provided with a plate-type and a triangular-type connecting plate for connecting with the crane.

[0011] The beneficial effects of the embodiments of the utility model are as follows: a fan for exhausting air downward is also provided on the upper part of the protective shell, and the wind blown by the fan blows away the dust, smoke, etc. in front of the sensor body, thereby enhancing the accuracy of the sensor body monitoring and reducing the interference of impurities. The motor is screwed to the adjustment rod through the connecting seat. When the detection angle of the sensor body needs to be adjusted, it is only necessary to start the motor, and the motor drives the adjustment rod to rotate forward and reverse by forward and reverse rotation, thereby realizing the angle adjustment of the sensor body. In particular, when the angle of the sensor body is changed during use, the monitoring angle is adjusted by the motor, and there is no need for manual climbing to make adjustments, thereby reducing labor intensity.

[0016] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0017] See also Figures 1 to 3The embodiment of the utility model discloses an intelligent anti-collision device for a crane, including a sensor body 1. The sensor body 1 can select one or more of a laser sensor, a microwave sensor, and an ultrasonic distance sensor, and can monitor moving objects and issue an alarm. An angle adjustment device is arranged on the back side of the sensor body 1, and the angle adjustment device is mainly composed of a mounting seat 2, a support rod 201, a support seat 3, and an adjustment rod 202. The mounting seat 2 is tightly connected to the sensor body 1, and the side of the mounting seat 2 is open, and a support rod 201 is hinged inside. The other end of the support rod 201 is provided with a support seat 3 connected to the crane, and the sensor body 1 is connected through the support seat to ensure stability.

[0018] In order to achieve flexible adjustment of the detection angle of the sensor body 1, an adjusting rod 202 is arranged between the supporting seat 3 and the mounting seat 2. One end of the adjusting rod 202 is connected to the mounting seat 2 through a spherical head. Such a design enables the adjusting rod 202 to rotate freely within a certain range, thereby driving the mounting seat 2 and the sensor body 1 to adjust the angle. A protective shell 101 is arranged on the outside of the sensor body 1. The upper part of the protective shell 101 protrudes outward to form a protective cover, which effectively prevents external objects from directly hitting the sensor body 1. At the same time, a fan 102 with downward air outlet is also arranged on the upper part of the protective shell 101. The wind blown by the fan 102 will blow away the dust, smoke, etc. in front of the sensor body 1, thereby enhancing the monitoring accuracy of the sensor body 1 and reducing the interference of impurities.

[0019] The support rod 201 is hinged to the support seat 3, and the adjusting rod 202 is arranged above the support rod 201 to form a quadrilateral structure. The extension and retraction of the adjusting rod 202 controls the pitch angle of the sensor body 1. The adjusting rod 202 is a screw rod. A fixing plate 301 is arranged on the upper part of the support seat 3. A strip-shaped adjusting hole is arranged in the middle position of the fixing plate 301. A sleeve 302 is hinged inside the adjusting hole. One end of the adjusting rod 202 is screwed inside the sleeve 302. By rotating the adjusting rod 202, it can be extended and retracted inside the sleeve 302, thereby driving the mounting seat 2 and the sensor body 1 to adjust the angle. The monitoring angle of the sensor body 1 is about 120 degrees. Due to the different use postures and models of the crane, if the sensor body 1 is directly installed to the side, the monitoring angle cannot meet the requirements. The adjusting rod 202 and the support rod 201 can be adjusted to a suitable angle according to different installation positions to meet the use requirements, so that the surrounding area of ​​the crane can be fully covered, blind spots can be reduced, and safety of use can be ensured.

[0020] In order to realize the automatic control of the adjustment rod 202, a motor 303 is set on one side of the fixing plate 301. The motor 303 is screwed to the adjustment rod 202 through the connecting seat. When the detection angle of the sensor body 1 needs to be adjusted, it is only necessary to start the motor 303. The motor 303 drives the adjustment rod 202 to rotate forward and reversely through forward and reverse rotation, thereby realizing the angle adjustment of the sensor body 1. In particular, after the angle of the sensor body 1 changes during use, the monitoring angle is adjusted by the motor 303, and there is no need for manual climbing to adjust, thereby reducing labor intensity. In order to enhance the stability of the device, a connecting spring 5 is set at the bottom of the mounting seat 2 and the supporting seat 3. The connecting spring 5 can buffer the vibration generated by the crane during movement or work to a certain extent, and assist the adjusting rod 202 to ensure the stable adjustment of the sensor body 1 and improve the use effect.

[0021] Finally, in order to meet the connection requirements of different installation positions of different cranes, plate-type and triangular-type connecting plates 4 are set on the side of the mounting seat 2. The plate-type connecting plate 4 can be installed on the side of the crane, and the triangular-type connecting plate 4 can be installed on the edge of the crane column. The device can be stably installed on the crane through the connecting plate 4 to ensure the use effect. By flexibly adjusting the detection angle of the sensor body 1, it can effectively avoid collision accidents of the crane during operation and improve work safety.
