Abstract
The utility model discloses a kind of safe and reliable, easy to operate hoisting crane windbreak anchoring device.It comprises the collar, the slotting axle suitable with collar inner circumferential, and be provided with socket below the described collar, described socket is provided with jack, and described jack internal diameter size is greater than slotting axle outside dimension, and described jack side is provided with limit switch.The utility model is applicable to the windbreak anchoring on hoisting crane.
Description
Technical field
The utility model relates to a kind of hoisting crane, particularly relates to a kind of girder be applicable on hoisting crane.
Background technology
The hoisting crane be under open-air atmosphere can be subject to the impact of wind; moved by wind in a non-operative state for preventing the hoisting crane of open work in orbit; avoid suffering disaster caused by a windstorm cause hoisting crane smooth, derail, the safety misadventure such as to tumble, usually can use anchoring device.At present, the M/C that anchoring device adopts usually is heavy, loaded down with trivial details and without electric interlocking installation, very dangerous, under there is hoisting crane anchoring states possibly, crane movements, cause ground drawing crack, or machinery draws bad, more serious may cause human safety issues.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of safe and reliable, easy to operate hoisting crane windbreak anchoring device.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises the collar, the slotting axle suitable with collar inner circumferential, and be provided with socket below the described collar, described socket is provided with jack, and described jack internal diameter size is greater than slotting axle outside dimension, and described jack side is provided with limit switch.
As preferably, described socket is provided with ground jack below jack, described ground jack internal diameter size is greater than slotting axle outside dimension.
As preferably, described slotting axle is provided with handle.
The utility model compared with prior art, has following obvious advantage and beneficial effect:
1, safe and reliable.Because the utility model adopts slotting axle to coordinate with jack with the collar, slotting axle, realize the automatically closed of limit switch or open, making hoisting crane enter work or off working state, make safe and reliable.
2, easy to operate.Because the utility model only need make slotting axle coordinate with jack with the collar or slotting axle, can realize reinstating and grappling of hoisting crane, operation is very easy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is utility model works view;
Fig. 3 is the utility model off working state schematic diagram.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail:
As shown in Figure 1 to Figure 3: the utility model comprises the collar 1, the slotting axle 2 suitable with the collar 1 inner circumferential, socket 3 is provided with below the collar 1, socket 3 is provided with jack 5, jack 5 internal diameter size is greater than slotting axle 2 outside dimension, jack 5 side is provided with limit switch 6, socket 3 is provided with ground jack 7 below jack 5, ground jack 7 internal diameter size is greater than slotting axle 2 outside dimension, inserts axle 2 and is provided with handle 8.
In use, the collar 1, socket 3 are arranged at the side of hoisting crane cross sill 10, when slotting axle 2 inserts the collar 1 position, limit switch 6 contact closes the utility model automatically, and crane travel mechanism switches on power, and enters mode of operation; When slotting axle 2 extracts the collar 1 position, insert the jack 5 of socket 3, and when inserting ground jack 7, enter hoisting crane anchoring states, limit switch 6 contact is opened automatically, and crane travel mechanism power cut-off, enters off working state, thus driver's maloperation damages hoisting crane or draws bad ground when effectively preventing hoisting crane anchoring states, avoid producing personal safety hidden danger simultaneously.
Claims (3)
