Abstract
The utility model provides a steel wire rope unbalance alarm device of a crane, which relates to steel wire ropes of a hoisting mechanism of the crane, solves the problem that according to a balanced lever device of a traditional hoisting mechanism, when one steel wire rope in two steel wire ropes is loosened or broken, an alarm cannot be immediately given to eliminate potential safety hazards, and is characterized in that a balanced lever supporting seat is connected with a balanced lever by using a balanced lever shaft; a cushioning device is arranged on the balanced lever supporting seat and is positioned below the balanced lever; one side of each end part of the balanced lever is respectively provided with a bracket; and limit switches are arranged on the brackets and above the corresponding positions of the two end parts of the balanced lever. The steel wire rope unbalance alarm device of the crane is particularly suitable for hoisting mechanisms of the crane in limited spaces.
Description
Technical field
The utility model relates to handling machinery, particularly the steel rope of crane hoisting mechanism.
Background technology
The compensating bar device of hoisting crane tradition lifting mechanism as shown in Figure 1, be installed on the compensating bar bearing (2) in the middle of the compensating bar (1), steel rope (4,5) is connected with compensating bar (1) by the steel rope wedge joint (3) or the heavy collar, adopt self lubrication bearing or oscillating bearing form in the middle of the compensating bar (1), when steel rope two ends discontinuity equalization, steel rope is during towards a certain direction beat, compensating bar just with self lubrication bearing or oscillating bearing be the center automatically rotation until balance position.When steel cable (4 or 5) destroyed, compensating bar (1) will run-off the straight, can cause very big impact to another root steel rope (5 or 4), and can not stop dipping and heaving immediately, has potential safety hazard.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of crane rope unbalance warning device, solve the compensating bar device of traditional lifting mechanism, when having a generation pine to break phenomenon in two steel ropes, the problem that can not report to the police immediately and eliminate safe hidden trouble.
The utility model is achieved through the following technical solutions:
The unbalance warning device of a kind of crane rope comprises: compensating bar, compensating bar bearing, steel rope wedge joint, left steel rope, right steel rope; The middle part of compensating bar is connected with the compensating bar bearing, the two ends of compensating bar are connected with left steel rope, right steel rope respectively by the steel rope wedge joint, it is characterized in that: described compensating bar bearing is connected with described compensating bar with a kind of compensating bar axle, be provided with shock absorber on the described compensating bar bearing, below being positioned at described compensating bar, side difference mounting bracket at described compensating bar both ends, on the described support, with compensating bar both ends correspondence position above, be provided with limit switch.
Between described compensating bar axle and the described compensating bar self lubrication bearing is installed.
The utility model compared with prior art has the following advantages and beneficial effect:
Because the utility model is provided with shock absorber below compensating bar; Limit switch is installed on support, therefore, when steel cable lost efficacy, compensating bar was run into the energy disperser on the bearing earlier, give buffer action of steel rope, when compensating bar continues to be inclined upwardly, can run into rack-mount limit switch, connect warning, when reporting to the police, electric-control system can cut off the main relay power supply of lifting mechanism immediately, stops dipping and heaving, eliminates safe hidden trouble.The utility model compact conformation is specially adapted to the crane hoisting mechanism of limited space.
Description of drawings
Fig. 1 is a kind of structural representation (front view) of hoisting crane tradition lifting mechanism compensating bar device;
Fig. 2 is structural representation of the present utility model (front view);
Fig. 3 is that the A of Fig. 2 is to view;
Fig. 4 is the B-B section-drawing of Fig. 2;
Fig. 5 is an action scheme drawing of the present utility model (when limit switch works).
Below in conjunction with accompanying drawing and by preferred embodiment the utility model is further described.
The specific embodiment
Shown in Fig. 2,3,4,5, the unbalance warning device of a kind of crane rope comprises: compensating bar 1, compensating bar bearing 2, steel rope wedge joint 3, left steel rope 4, right steel rope 5; The middle part of compensating bar 1 is connected with compensating bar bearing 2, and the two ends of compensating bar 1 are connected with left steel rope 4, right steel rope 5 respectively by steel rope wedge joint 3; A kind of compensating bar axle 8 of described compensating bar bearing 2 usefulness is connected with described compensating bar 1, be provided with shock absorber 7 on the described compensating bar bearing 2, below being positioned at described compensating bar 1, side difference mounting bracket 10 at described compensating bar 1 both ends, on the described support 10, with compensating bar 1 both ends correspondence position above, be provided with limit switch 6.
Self lubrication bearing 9 is installed between described compensating bar axle 8 and the described compensating bar 1.
During normal operation, shock absorber and limit switch are inoperative, and when steel cable lost efficacy, the shock absorber that is contained on the bearing 2 was run in the compensating bar run-off the straight earlier, reduces the impulsive force of steel rope; When continuing slowly swing, compensating bar is run into the limit switch 6 that is contained in support 10, and warning is reported to the police, and electric-control system can cut off the main relay power supply of lifting mechanism immediately, stops dipping and heaving, and total system is protected.
Claims (2)
1. unbalance warning device of crane rope, comprise: compensating bar (1), compensating bar bearing (2), steel rope wedge joint (3), left side steel rope (4), right steel rope (5), be installed on the compensating bar bearing (2) in the middle of the compensating bar (1), compensating bar bearing (2) two ends are connected with compensating bar (1) by steel rope wedge joint (3), it is characterized in that: described compensating bar bearing (2) is connected with compensating bar (1) with a kind of compensating bar axle (8), on compensating bar bearing (2), be positioned at compensating bar (1) below and be provided with shock absorber (7), side difference mounting bracket (10) at compensating bar (1) both ends, on support (10), with compensating bar (1) both ends correspondence position top, be provided with limit switch (6).
2. according to the unbalance warning device of the described crane rope of claim 1, it is characterized in that: between described compensating bar axle (8) and compensating bar (1) self lubrication bearing (9) is installed.
