Description

Technical Field

[0001] The utility model relates to the technical field of crane equipment application, in particular to a crane safety induction protection device. Background Art

[0002] In the production process of industrial product exporting enterprises, crane equipment is widely used to lift heavy objects, such as aluminum coils, large tools and other objects weighing several tons. During the lifting process of heavy objects, personnel are often required to first tie the heavy objects to the crane hook with slings or wire ropes, and then lift them. At this time, personnel are often under or very close to the heavy objects. It is very dangerous for personnel to stand under the heavy objects being lifted. People can easily be injured by crane failure or tilt. Therefore, it is necessary to further optimize the operating structure of factory crane driving to achieve early warning and protection of the personal safety of lifting operators and ensure the overall efficiency and safety of lifting. Utility Model Content

[0003] The utility model provides a crane safety induction protection device to solve the problems existing in the above background.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A crane safety induction protection device includes a crane trolley, a crane trolley is movably provided on the crane trolley, a crane controller is provided on the crane trolley, a projection induction light is fixedly provided on the crane trolley, a heavy object is connected to the bottom of the crane trolley, and a projection light area is formed on the outside of the heavy object.

[0006] Furthermore, a crane remote control is provided in the hand of the operator on the side of the heavy object, and the crane remote control is electrically connected to the crane controller and the projection induction light.

[0007] Furthermore, a lifting rope is fixedly provided at the bottom of the crane trolley, a lifting hook is connected to the bottom of the lifting rope, and the weight is arranged at the bottom of the lifting hook.

[0008] Furthermore, the projection light area is formed by the downward illumination of the projection sensor lamp, and the projection light area is covered on the periphery of the heavy object.

[0009] Furthermore, a human body sensing radar is installed inside the projection induction lamp, and the human body sensing radar is a B1H54 model.

[0010] The utility model has the following beneficial effects:

[0011] The utility model provides a crane safety induction protection device. By adding a laser projection sensor light to the crane trolley, the projection sensor light is illuminated downward and forms a projection light area covering the outside of the hoisted heavy object. When the projection sensor light, the operator's crane remote control and the crane controller are interlocked, it is effectively realized that when the operator enters the laser radar projection light area, the crane controller receives a signal and stops lifting; when the operator leaves the projection light area, the crane controller receives a signal and continues to lift the heavy object, thereby greatly ensuring the safety of the operator during the heavy object lifting process. This solves the problem that in the current application of crane driving in factories, it is difficult for the crane to identify the operator's position during operation, which often causes the operator to mistakenly enter the dangerous bottom of the hoisted cargo, which is very likely to cause the cargo to fall and injure the operator's personal safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the overall structure of the utility model.

[0013] The meanings of the reference numerals are as follows:

[0014] 1. Crane trolley; 2. Crane trolley; 3. Projection sensor light; 4. Crane controller; 5. Lifting rope; 6. Hook; 7. Heavy object; 8. Operator; 9. Crane remote control; 10. Projection light area. DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 As shown, a crane safety sensing protection device includes a crane trolley 1, a crane trolley 2 is movably provided on the crane trolley 1, a crane controller 4 is provided on the crane trolley 2, a projection induction light 3 is also fixedly provided on the crane trolley 2, a weight 7 is connected to the bottom of the crane trolley 2, and a projection light area 10 is formed on the outside of the weight 7.

[0017] The operator 8 on the side of the heavy object 7 has a crane remote control 9 in his hand, and the crane remote control 9 is electrically connected to the crane controller 4 and the projection sensor light 3.

[0018] A lifting rope 5 is fixedly provided at the bottom of the crane trolley 2 , a lifting hook 6 is connected to the bottom of the lifting rope 5 , and the weight 7 is arranged at the bottom of the lifting hook 6 .

[0019] The projection light area 10 is formed by the downward illumination of the projection sensor lamp 3 , and the projection light area 10 is covered around the periphery of the heavy object 7 .

[0020] In specific applications, when the crane trolley 1 is lifting a heavy object 7, there is a great safety hazard in the area below it, which is an unsafe state. The heavy object 7 may fall suddenly due to an accident and injure the operator 8 below, causing a safety accident. The utility model installs a projection sensor light 3 on the crane trolley 2 to illuminate the area under the heavy object 7 that may injure the operator. During the lifting operation, the crane operator 8 can lift the heavy object 7 and

[0021] After the lifting rope 5 and the hook 6 are installed well, the crane remote control 9 is used to control the drum of the crane trolley 2 to rotate the lifting rope 5 to lift the heavy object 7. At the same time of lifting, the crane projection sensor light 3 is started at the same time, and a projection light area 10 is projected to the area of the ground operator 8. The projection sensor light 3 is always in working state and sends a human body sensing laser radar to the area. During this period, if the operator 8 is in this area, the laser sensing radar of the projection sensor light 3 senses that there is someone here and warns of unsafe conditions. It will feed back the interlocking signal to the crane controller 4 and cut off the power to stop the lifting action of the crane, thereby ensuring that the operator 8 is not in the dangerous area formed by the projection light area 10, and achieving early warning isolation; when the operator 8 is not in the dangerous area formed by the projection light area 10, the crane can lift the heavy object normally, and the crane trolley 1 and the crane trolley 2 can move to realize the front, back, left and right lifting of the heavy object 7 in the factory. The device effectively realizes the safety warning protection function of the crane equipment through the interlocking of the laser sensing projection sensor light 3 and the crane controller 4, greatly avoiding the occurrence of heavy objects 7 falling and injuring people in the factory, thereby improving the overall efficiency and safety of the crane driving equipment application. Therefore, the protection device has good practicality.
