Abstract
The utility model discloses a detection and control device for preventing a crane drum from jumping, wherein a base is arranged on a rack outside the drum shaft; a sensing device is arranged on the base; the induction device control switch and a limit device control switch of the crane are connected in series in a winding drum control electric loop; the alarm device also comprises an alarm device, and a trigger switch of the alarm device is a control switch of the induction device. The utility model has the advantages that: (1) when the winding drum and the deceleration transversely move, the transverse movement is found at the first time. (2) When the problem occurs, the device can stop the vehicle for the first time.
Description
Technical Field
The utility model relates to an electromechanical technical field specifically is an alarm and protection device of hoist.
Background
The crane is easy to collide with each other due to various factors during daily operation. When collision happens, part of kinetic energy is transferred to a lifting mechanism of the crane, so that the winding drum and the deceleration transversely move. Because there is a large amount of greasy dirt between most hoist reel and the speed reduction, lead to discovery that can not be timely, in addition, the reel takes place the drunkenness with the speed reduction after, initial stage drunkenness displacement has the reciprocity, and reconversion is after certain period promptly again, makes the professional be difficult to judge and inspect more.
If the reel moves transversely with the deceleration, the transverse displacement can cause serious consequences if the transverse displacement is not found in time. Consequence 1, the lifting limit position is inaccurate, if the limit is upwards deviated, the hook head accident of the day can be generated, if the control is not good, the steel wire rope can be broken, and the hook head can fall, if people exist on the ground or equipment, the unimaginable serious consequence can be caused. Consequence 2, in the operation process of the winding drum, the winding drum is separated from the speed reducer, the weight hung below directly falls together with the hook head group and the hoisting hanger, and meanwhile, the winding drum group can fly out due to the force given by the weight below after being separated, and if people exist on the ground or equipment can cause unimaginable serious consequences.
Therefore, a device for detecting and controlling the position of the spool is urgently needed.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims to provide a detection and control device for preventing the position of a crane drum from being crossed, wherein a base is arranged on a rack outside the drum axial direction; a sensing device is arranged on the base; the induction device control switch and the limit device control switch of the crane are connected in series in the reel control electric loop.
The alarm device also comprises an alarm device, and a trigger switch of the alarm device is a control switch of the induction device.
The utility model has the advantages that: after the reel bumps and takes place lateral displacement, can trigger response position control switch, this switch is normally closed switch on the one hand, can break off reel drive circuit when receiving to trigger, switches on warning circuit simultaneously, has guaranteed: (1) when the winding drum and the deceleration transversely move, the transverse movement is found at the first time. (2) When the problem occurs, the device can stop the vehicle for the first time.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure, 1 is a winding drum, 2 is a bearing seat, 3 is a limit device control switch, and 4 is an induction device control switch;
FIG. 2 is a schematic diagram of electrical circuit control;
in the figure, U is a power supply of the alarm device, M is a drum driving motor, and L is the alarm device.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings, wherein, as shown in the drawings, a base is arranged on the frame at the axial outer side of the winding drum 1; a sensing device is arranged on the base; the induction device control switch and the limit device control switch of the crane are connected in series in the reel control electric loop. The sensing device may be an infrared sensing switch;
the alarm device also comprises an alarm device, and a trigger switch of the alarm device is a control switch of the induction device.
The infrared inductive switch and the alarm device can be commercially available products.
The principle of the utility model is that: when the winding drum moves axially, the induction device control switch is triggered, the switch and the limit device control switch are both in a normally closed state in a control loop and are triggered to be disconnected, and the switch and the limit device control switch are connected in series, so that the winding drum driving loop is disconnected when any one switch is triggered; when the limit device control switch is disconnected with the reel control loop, the power supply loop of the alarm device is connected, so that the alarm device starts to work.
Claims (2)
1. The utility model provides a position detection control device is prevented scurrying by hoist reel which characterized in that: a base is arranged on the rack on the outer side of the drum shaft; a sensing device is arranged on the base; the induction device control switch and the limit device control switch of the crane are connected in series in the reel control electric loop.
2. The crane drum position-fleeing prevention detection control device according to claim 1, characterized in that: the alarm device also comprises an alarm device, and a trigger switch of the alarm device is a control switch of the induction device.
