According to the technical scheme, the crane load power take-off device comprises a fixing base installed on a large pull rod; a balance beam is hinged to the fixing base; a power take-off pulley used for making contact with a lifting steel wire rope is arranged at one end of the balance beam, and a counterweight matched with the power take-off pulley is arranged at the other end of the balance beam; a pressure sensor is arranged on the side, adjacent to the counterweight, of the fixing base; the balance beam can make contact with the pressure sensor when swinging, and the pressure sensor is connected with a crane controller. The crane load power take-off device is compact in structure, convenient to use and capable of effectively preventing a crane from working at an overload and guaranteeing the working reliability and service life of the crane.
Description
Technical field
The present invention relates to a kind of power takeoff, especially a kind of crane load power takeoff, belongs to the technical field of hoisting crane.
Background technology
At present, hoisting crane is in harbour, stockyard are widely used, the bulk goods such as lifting sandstone, ore, coal, when but existing hoisting crane uses, the situation that workman's overburden uses happens occasionally, this just causes stealthy destruction to hoisting crane, affects the service life of hoisting crane, has serious potential safety hazard.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of crane load power takeoff, its compact conformation, easy to use, can effectively avoid hoisting crane to work overloadingly, guarantee reliability and the service life of hoisting crane work.
According to technical scheme provided by the invention, described crane load power takeoff, comprise the permanent seat be installed on large pull bar, described permanent seat is hinged with equalizing bar, being provided with the power taking pulley for contacting with hoist rope in the end, one end of described equalizing bar, being provided with the counterweight matched with power taking pulley at the other end of described equalizing bar; Pressure sensor is provided with in the side of the contiguous counterweight of permanent seat; Equalizing bar can contact with pressure sensor when swinging, and described pressure sensor is connected with crane controller.
The two ends of described large pull bar are all arranged for being connected the wire rope pulley coordinated with hoist rope.
Described equalizing bar is hinged on the upper end of permanent seat by hinge.
Advantage of the present invention: hinged equalizing bar on permanent seat, equalizing bar is connected with hoist rope by power taking pulley, permanent seat is arranged the pressure sensor being used for detected pressures value, by coordinating of pressure sensor and power taking pulley, the weight that can realize promoting hoist rope load is effectively monitored, crane controller can adjust the power supply state of hoisting crane according to the force value that pressure sensor transmits, thus can effectively avoid hoisting crane to work overloadingly, guarantee reliability and the service life of hoisting crane work, compact conformation, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Description of reference numerals: 1-power taking pulley, 2-equalizing bar, 3-hinge, 4-permanent seat, 5-pressure sensor, 6-counterweight, 7-hoist rope, the large pull bar of 8-and 9-wire rope pulley.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1: in order to effectively avoid hoisting crane to work overloadingly, guarantee reliability and the service life of hoisting crane work, the present invention includes the permanent seat 4 be installed on large pull bar 8, described permanent seat 4 is hinged with equalizing bar 2, being provided with the power taking pulley 1 for contacting with hoist rope 7 in the end, one end of described equalizing bar 2, being provided with the counterweight 6 matched with power taking pulley 1 at the other end of described equalizing bar 2; Pressure sensor 5 is provided with in the side of the contiguous counterweight 6 of permanent seat 4; Can contact with pressure sensor 5 when equalizing bar 2 swings, described pressure sensor 5 is connected with crane controller.
Particularly, the axis of permanent seat 4 is mutually vertical with the axis of large pull bar 8, and equalizing bar 2 is hinged on the upper end of permanent seat 4, and equalizing bar 2 can swing by a small margin on permanent seat 4.Power taking pulley 1 is positioned at one end of equalizing bar 2, effectively can be contacted by power taking pulley 1 with hoist rope 7, and realizes the available protecting to hoist rope 7.Weight and the power taking pulley 1 of counterweight 6 are suitable, thus under normally, equalizing bar 2 is in a kind of state of equilibrium.Pressure sensor 5 is arranged on permanent seat 4, and is positioned at the side of contiguous counterweight 6.Can promote load by hoist rope 7, during the varying in weight of load, the contact condition between hoist rope 7 from power taking pulley 1 is different.When the weight that hoist rope 7 promotes load exceedes rated weight, power taking pulley 1 can be lifted, after power taking pulley 1 is lifted, equalizing bar 2 swings, and now, equalizing bar 2 can contact with pressure sensor 5, and pressure sensor 5 can detect corresponding force value.The force value of detection transfers in crane controller by pressure sensor 5, crane controller is after the force value receiving pressure sensor 5 transmission, can determine that weight hoist rope 7 promoting load exceedes rated weight, now, crane controller can cut off the power supply state of hoisting crane power supply, only have when weight hoist rope 7 promoting load is not more than rated weight, crane controller just can connect the power supply state of hoisting crane power supply.Crane controller is the control center controlling hoisting crane work, crane controller can adopt existing conventional form, when specific works, crane controller can be in electriferous state all the time, and the force value of pressure sensor 5 transmission can be received, thus effectively can control the state that hoist rope 7 promotes load.
The two ends of described large pull bar 8 are all arranged for being connected the wire rope pulley 9 coordinated with hoist rope 7.Described equalizing bar 2 is hinged on the upper end of permanent seat 4 by hinge 3.
In the embodiment of the present invention, the center of equalizing bar 2 is hinged on the upper end of permanent seat 4 by hinge 3, and the lower end of permanent seat 4 is fixedly connected with large pull bar 8.Hoist rope 7 contacts with two wire rope pulleys 9, effectively to support the hoist rope 7 during work.
The present invention is hinged equalizing bar 2 on permanent seat 4, equalizing bar 2 is connected with hoist rope 7 by power taking pulley 1, permanent seat 4 is arranged the pressure sensor 5 being used for detected pressures value, by coordinating of pressure sensor 5 and power taking pulley 1, the weight that can realize promoting hoist rope 7 load is effectively monitored, crane controller can adjust the power supply state of hoisting crane according to the force value that pressure sensor 5 transmits, thus can effectively avoid hoisting crane to work overloadingly, guarantee reliability and the service life of hoisting crane work, compact conformation, easy to use.
