Abstract
Description
Technical Field
[0001] The utility model relates to the field of cranes, in particular to a crane state monitoring device. Background Art
[0002] When a crane is lifting, it is necessary to always pay attention to the situation near the hoisted object. When lifting at high altitude or long distance, the driver cannot clearly observe the environment near the hoisted object with the naked eye, which poses certain safety hazards. The existing technology monitors the lifting area by installing a vertical downward camera at the head of the boom and directly above the hook. When the hoisted object is small, the existing technology can play a certain monitoring role, but when the hoisted object is large or the hoisting height is high and close to the camera, the camera of this type of device is easily blocked by the hoisted object and cannot detect the situation directly below the hoisted object. During the lifting operation, directly below the hoisted object is the key target point for hoisting into place, and the existing technology cannot meet the monitoring needs.
[0003] Therefore, it is necessary to develop a lifting status monitoring device for cranes to clearly observe or accurately monitor the conditions of the lifting points. Utility Model Content

[0006] Wherein, a mounting hole is provided on the main bracket.
[0007] Wherein, the mounting card passes through the mounting hole on the main bracket and is fixedly connected to the main bracket through a fixing nut.
[0008] Wherein, the number of the damping blocks is 2, and the two damping blocks are respectively installed on both sides of the weight pendulum rod.
[0009] Wherein, the weight pendulum rod and the damping block are both provided with through holes, and the rotating shaft passes through the corresponding through holes between the two side supports, the weight pendulum rod and the damping block.
[0010] Wherein, the monitor is a camera and / or a laser radar.
[0011] Wherein, the monitor faces the hoisted object on the crane.
[0012] Beneficial effects: Compared with the prior art, the utility model has the following significant advantages: the utility model can be easily installed on a boom that is close to the height of the target lifting point of the crane, monitor the front hook area, clearly observe or accurately monitor the situation of the lifting point, thereby helping the crane driver to judge the lifting environment and increase the safety of lifting. The utility model can be quickly installed in a suitable position according to the lifting position and blind spot before lifting. During the lifting process, the device can be used to continuously monitor the target lifting area, thereby effectively reducing the lifting risk and improving the lifting efficiency.

[0016] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0017] The lifting state monitoring device of the utility model comprises a main support 2, which is connected to a crane boom 8 through a mounting card 1, two side supports extending from the main support 2, through holes are provided in the middle of the two side supports, a weight swing rod 4 and a damping block 5 are provided in the middle of the two side supports, and the two side supports, the weight swing rod 4 and the damping block 5 are fixed by a rotating shaft 6 and its matching nuts passing through them; a monitor 3 is provided on the top of the weight swing rod 4. Among them, a mounting hole is provided on the main support 2. The mounting card 1 passes through the mounting hole on the main support 2 and is fixedly connected to the main support 2 through a fixing nut 7. The number of damping blocks 5 is 2, and two damping blocks 5 are respectively installed on both sides of the weight swing rod 4. Both the weight swing rod 4 and the damping block 5 are provided with through holes, and the rotating shaft 6 passes through the corresponding through holes between the two side supports, the weight swing rod 4 and the damping block 5. The monitor 3 is a camera or / and a laser radar. The monitor 3 faces the hoisting object 9 on the crane.
[0018] When in use, the device is quickly installed and fastened using the mounting card 1 that matches the crane boom. The device weight pendulum 4 and the monitor 3 form a union, with the center of gravity at the weight. The principle that the center of gravity is vertically downward is used to keep the camera in a horizontal direction, so that the target hoisting area can be easily detected. The damping block can prevent the camera from continuously shaking when the boom where the detection device is located swings, and the damping strength of the damping block will not prevent gravity from driving the weight pendulum to rotate. The mounting card 1 matches the crane boom 8 to be installed, and the card sleeve passes through the mounting hole on the main bracket 2 after the boom rod, and the mounting bracket is firmly fixed on the crane boom 8 with the mounting card fixing nut 7; the main bracket 2 extends two side supports, and a through hole is punched in the middle of the support, and the rotating shaft 6 can be inserted into the middle through hole of the support, and at the same time passes through the damping block 5 and the heavy hammer pendulum 4, and then the several parts are connected and fixed by nuts; wherein there are two damping blocks respectively installed on both sides of the heavy hammer pendulum 4, and the heavy hammer pendulum 4 has a matching through hole at the matching position with the rotating shaft 6; the monitor 3 is mechanically connected with the heavy hammer pendulum 4 so that the monitor 3 and the rotating shaft 6 are in a vertical state or a fixed angle, and one of the installation methods is to fix it by installing screws. The mechanical connection of the heavy hammer pendulum 4 makes the monitor 3 and the rotating shaft 6 in a vertical state or a fixed angle, and it can also be appropriately changed to make the angle between the monitor 3 and the rotating shaft 6 adjustable.
