Abstract
The invention relates to a lifting limiting device for ship crane. The device comprises a basic arm, one end of the basic arm is provided with an electromagnetic unloading valve, the other end of the basic arm is provided with a pulley, the bottom of the pulley is connected to a lifting hook through a steel wire, the head part of the pulley is provided with a limiting switch; the middle part of the basic arm is provided with an automatic take-up reel, one end of the automatic take-up reel is connected to the electromagnetic unloading valve, the other end of the automatic take-up reel is connected to the limiting switch; a steel wire arranged on the top part of the lifting hook is connected to a heavy block, and the heavy block is connected to the lifting switch through a steel wire. The structure of the device is impact and reasonable. The device achieves the lifting limiting function by combining an electromagnetic valve, an automatic take-up reel, and a limiting switch together. When the telescopic crane stretches out or retracts in, the automatic take-up reel automatically stretches out or retracts in the wire, and the device is agile and reliable.
Description
Technical field
The present invention relates to weight-lifting equipment technical field, especially a kind of inhibiting device that hoists for deck crane that is applicable to stretch on heavy industry.
Background technology
Deck crane, is a kind of large deck machinery on ship, and it is a kind of equipment of ship loading and unloading goods.
At present, in the middle of deck crane, what the most inhibiting device that hoists adopted is hydraulic stroke valve inhibiting device, this inhibiting device is suitable in straight arm type hoisting crane, in telescopic crane, just can not realize the limit function that hoists, its use has limitation, to telescopic crane, has brought inconvenience.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of inhibiting device that hoists for deck crane rational in infrastructure, thereby meets the limit function that hoists on telescopic crane, uses flexibly, and functional reliability is good.
The technical solution adopted in the present invention is as follows:
A kind of inhibiting device that hoists for deck crane, comprise basic arm, one end of described basic arm is provided with unloading electromagnetic valve, and the other end of described basic arm is provided with coaster, described arse is by steel rope connecting shackle, and described coaster head is also provided with limit switch; Be positioned at basic arm middle part automatic wire-collecting box is installed, one end of automatic wire-collecting box connects unloading electromagnetic valve, and the other end of automatic wire-collecting box connects limit switch; Be positioned on the steel rope at suspension hook top and be connected with pouring weight, described pouring weight is connected with limit switch by steel wire.
Further improvement as technique scheme:
Described automatic wire-collecting box is connected with limit switch with unloading electromagnetic valve respectively by steel wire.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, reasonable, by unloading electromagnetic valve and automatic wire-collecting box, and the combination of limit switch meets the limit function that hoists of telescopic crane, when telescopic crane is when doing the action of stretching out and retracting, automatic wire-collecting box now just can stretch out electric wire automatically and retract, and uses flexibility and reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, unloading electromagnetic valve; 2, automatic wire-collecting box; 3, limit switch; 4, pouring weight; 5, suspension hook; 6, basic arm; 7, coaster.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the inhibiting device that hoists for deck crane of the present embodiment, comprises basic arm 6, one end of basic arm 6 is provided with unloading electromagnetic valve 1, the other end of basic arm 6 is provided with coaster 7, and coaster 7 bottoms are by steel rope connecting shackle 5, and coaster 7 heads are also provided with limit switch 3; Be positioned at basic arm 6 middle parts automatic wire-collecting box 2 is installed, one end of automatic wire-collecting box 2 connects unloading electromagnetic valve 1, and the other end of automatic wire-collecting box 2 connects limit switch 3; Be positioned on the steel rope at suspension hook 5 tops and be connected with pouring weight 4, pouring weight 4 is connected with limit switch 3 by steel wire.
Automatic wire-collecting box 2 is connected with limit switch 3 with unloading electromagnetic valve 1 respectively by steel wire.
In actual use procedure, when suspension hook 5 risings touch pouring weight 4, the electromagnetic valve of unloading electromagnetic valve 1 obtains electric, starts off-load protection.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
