Description
Technical field
The utility model relates to a kind of tower crane safety monitoring system weight power takeoff, belongs to elevator machinery security protection technology field.
Background technology
Tower crane is building and the mega project requisite key equipment of constructing, and is one of significant important equipment of construction enterprises' equipment.Tower crane safety monitoring system is widely used as a kind of safety precautions of tower crane.Because lifting overload causes the crane steel structure distortion even occurs that hoisting crane integral body is overturned thereby the serious accident that causes happens occasionally, at elevator machinery tower crane safety monitoring system being installed is the important assurance that prevents that such event from taking place.Conventional tower crane safety monitoring system power takeoff is by two proving rings, one end is fixed, an other end is gone here and there on the bearing pin sensor with pulley, fix with nut-lock washer, the pulley of tower machine is around the steel rope of hoisting heavy, the pulling force that steel rope is subjected to, be applied on the pulley, when causing proving ring to be subjected to the pulling force distortion, the axial pin type sensor that connects two proving rings is subjected to the pulling force output signal of pulley, and instrument is handled the weight signal intelligent decision and relay moves.Prevent the purpose that overloads thereby reach protection tower machine, the load lifting limiter power takeoff of this structure is installed relatively difficulty at the tower machine, installs too loaded down with trivial details, to structure special any just can not install, restriction is received in power taking, weight signal is inaccurate.The overall stability of tower crane safety monitoring system is affected.Present conventional hoisting capacity power takeoff is being installed the many problems that also exist.
Summary of the invention
The purpose of this utility model is in order to overcome the problems that traditional hoisting capacity power taking exists, to disclose a kind of hoisting capacity power takeoff and be used for safety monitoring system collection weight signal.
The technical solution of the utility model is, stretch to the midway location of load lifting limiter pulley from the tower cap at hoist rope, steel rope is around a pulley, pulley and support are fixed with pivot pin, one end of support is held power taking with a S type sensor, and the other end of S type sensor is fixed on the tower machine steel structure with the adapter plate assembly.When the tower machine hung weight, steel rope tension caused the pulley on the steel rope to be subjected to pulling force, is subjected to the signal that pulling force output is directly proportional with weight by S type sensor, and signal is handled through safety monitoring system, and realization is to the safety guard-safeguard of tower crane.
The utility model safety monitoring system power takeoff is made up of pulley, pivot pin, pulley yoke assembly, screw rod and nut, S type sensor, adapter plate and bolt.Pulley is fixed on the pulley bracket with pivot pin; S type sensor screw rod, nut and bolt is tightened connection; One end of S type sensor is connected with pulley assembly by screw rod, and the other end of S type sensor is connected with adapter plate by bolt.Adapter plate is fixed on by U-bolt on the oblique rollering steel pipe of tower machine, the steel wire penetrating pulley from the tower cap to the weight limits device.
Principle of work and the working process of the utility model safety monitoring system power takeoff are as follows: steel wire loop is on pulley, pulley is fixed on the pulley assembly with pivot pin, pulley assembly connects S type sensor, the S sensor is connected with adapter plate by bolt, and adapter plate is fixed on the tower machine oblique rollering steel pipe by U-bolt.When the tower machine hangs weight, steel rope is tightened, pulling pulley and pulley assembly, S type sensor is subjected to the pulling force of pulley assembly, the weight signal that output is directly proportional with weight, and instrument is handled by calculated signals, the output switching value, the control tower machine reaches the security monitoring to the tower machine.
The beneficial effects of the utility model are, after adopting the utility model structure, act on the variable quantity of making a concerted effort on the pulley when directly measuring the lifting of tower machine exactly by lineoutofservice signal pull, give safety monitoring system by S type sensor output signal, action takes place and cuts off corresponding control loop in the instrument Based Intelligent Control, has ensured the safety of hoisting crane.
The utility model is applicable to the safety guard-safeguard monitored control system power taking of various hoisting cranes.

The specific embodiment
The specific embodiment of the present utility model as shown in Figure 1, Figure 2, Figure 3 and Figure 4.
Fig. 1 is present embodiment safety monitoring system power takeoff structural representation, and present embodiment safety monitoring system power takeoff is made up of pulley 1, pivot pin 2, pulley yoke assembly 3, screw rod 4 and nut 5, S type sensor 6, adapter plate 8 and bolt 7.
On the steel rope in the middle of the pulley at hoisting crane from the tower cap to the weight limits device, steel wire penetrating pulley 1, pulley 1 usefulness pivot pin 2 is fixed on the pulley bracket 3, and with spring cotter lock shaft pin 2, guarantees that pulley pulley 1 rotates flexibly, does not block.S type sensor 6 usefulness double-screw bolts 4, nut 5 and screw rod 7 are tightened connection, wherein will fill up spring washer and flat gasket.One end of S type sensor 6 is connected with pulley assembly 3 by screw rod 4; The other end of S type sensor 6 is connected with adapter plate 8 by bolt 7, must tighten with nut 5 after two ends install, and guarantees not become flexible.
Adapter plate 8 is fixed on by U-bolt on the oblique rollering steel pipe of tower machine, and is essential solid and reliable, can not become flexible, and bad phenomenon such as rocks.Eyelet bolt 7 both sides and adapter plate need be adorned packing ring by the spring cotter place.After above installation site was determined, pulley 1 and S type sensor 6 state that is in line guaranteed that S type sensor 6 is spent by force direction vertical with tower machine steel rope 90, as shown in Figures 2 and 3.
When the tower machine hangs weight, steel rope is tightened, pulling pulley and pulley assembly, S type sensor is subjected to the pulling force of pulley assembly, the weight signal that output is directly proportional with weight, and instrument is handled by calculated signals, the output switching value, the control tower machine reaches the security monitoring to the tower machine.Its simple installation, output signal is accurate, not influenced by external electromagnetic and mains fluctuations.Freight weight limit is highly sensitive, and is more convenient than present power takeoff Installation and Debugging.
