Description
Technical Field
The invention belongs to the technical field of crane accessories, and relates to a lifting hook warning device.
Background
The crane is a multi-action hoisting machine for vertically lifting and horizontally carrying a weight within a certain range, and at present, the crane has become an indispensable mechanical device in industrial production. In order to improve the speed of industrial production, many enterprises are unavoidably required to carry out necessary lifting operation at night, and when the crane is used at night, because light is darker, potential safety hazards can be brought to lifting operation, and especially when no goods are lifted on the lifting hook, the lifting hook is difficult to be perceived by people, so that the lifting hook can touch workers in the moving process, and danger occurs. Therefore, people develop the related lifting hook warning device, and the lifting hook warning device is arranged on the lifting hook of the crane, so that surrounding workers are reminded to pay attention to avoiding, and the purpose of reducing potential safety hazards is achieved.
The lifting hook alarm device (CN 208747491U) of the tower crane comprises an L-shaped bracket arranged in an inner cavity of an installation shell, wherein a control plate is fixed on one side of the upper part of a flat plate of the L-shaped bracket through a screw, a storage battery is fixed on the other side of the upper part of the flat plate of the L-shaped bracket through a fixing frame, and an alarm is fixed on one side of the lower part of the flat plate of the L-shaped bracket through a fixing support plate; an ultrasonic ranging sensor is fixed on a vertical plate at the lower part of the L-shaped bracket, and the ultrasonic ranging sensor is provided with a plastic loudspeaker; the two sides of the installation shell are respectively fixedly provided with a wing plate, and each wing plate is fixedly connected with a group of fixed irons through iron-absorbing fixing screws. The alarm device can only be installed on the outer wall of the side part of the lifting hook, so that when a worker is positioned on one side opposite to the alarm device, the alarm light emitted by the alarm device can be shielded by the lifting hook and is difficult to be perceived, the alarm device has a vision blind area when in use, the alarm effect of the alarm device is greatly influenced, and certain potential safety hazards still exist in the lifting process.
When the problem that the lifting safety is lower because of the visual blind area when the lifting hook alarm device is used in the current field is solved, the two alarm devices are usually adopted to be respectively fixed on the side walls of the lifting hook in different directions, so that the visual blind area is avoided, and the safety of lifting operation is improved.
Disclosure of Invention
The invention aims to solve the problems in the prior art, and provides a lifting hook warning device, which solves the problem of poor warning effect caused by visual blind areas in the use process of the existing lifting hook warning device and ensures stable installation of the lifting hook warning device.
The aim of the invention can be achieved by the following technical scheme: the utility model provides a lifting hook alarm, includes base, magnetism absorption spare and sets up the warning light on the base, its characterized in that, magnetism absorption spare articulates on the bottom surface of base and can follow the direction swing that is close to or keeps away from the base bottom surface, the bottom of base still is connected with flexible adsorption structure, flexible adsorption structure has two at least and is slice and can adsorb in the flexible adsorption part on metal surface.
The top surfaces of the lifting hooks of the conventional cranes in the market at present are all arc-surface structures. In this lifting hook alarm, the applicant adopts articulated mode to install the magnetic adsorption piece on the bottom surface of base to the magnetic adsorption piece can be followed and be close to or keep away from the direction swing of base bottom surface, and such design makes when installing lifting hook alarm on the top surface of lifting hook, and the magnetic adsorption piece can carry out adaptive angle adjustment according to the radian of lifting hook top surface, thereby guarantees to have great area of contact between magnetic adsorption piece and the top surface of lifting hook, promotes adsorption effect.
However, the magnetic absorption part adopts a hinged connection mode, so that the absorption area can be ensured to be larger, but the magnetic absorption part has the defect that the hinge is not in hard connection, if the base is fixed by only relying on the magnetic absorption part, the base can be rocked due to the rocking of the lifting hook in the lifting hook moving process, and if the rocking degree is larger, the risk that the lifting hook warning device falls off exists. To this end, the applicant has made further improvements by adding a flexible adsorption structure to the bottom of the base. Specifically, the flexible adsorption structure is provided with at least two flexible adsorption parts capable of being adsorbed on the metal surface, the flexible adsorption parts are sheet-shaped and flexible, and the flexible adsorption parts are guaranteed to be well attached to the side surface of the lifting hook and have a larger attaching area. Through setting up flexible adsorption structure for the lifting hook attention device can laminate the flexible adsorption device respectively on the preceding, trailing flank of lifting hook when the installation, carries out further fixed to the lifting hook attention device, has avoided the magnetism to adsorb the piece simultaneously and has appeared rocking, has better stability after guaranteeing that the lifting hook attention device is installed.
Obviously, this lifting hook alarm is through the design that can swing magnet adsorption piece and flexible adsorption structure combined together for the lifting hook alarm can be stably installed on the top surface of lifting hook, thereby makes the staff all can see the warning light that the lifting hook alarm sent all around, has avoided appearing the vision blind area, has promoted the security of warning effect and lifting by crane the operation greatly.
