The tower crane test device has features of simple structure, simple test operation, and more accurate and scientific test result.
Description
Technical field
The utility model relates to a kind of proving installation of crane, and particularly a kind of tower crane is surveyed the proving installation of lineoutofservice signal pull.
Background technology
At present, existing every tower machine of tower crane all will be with many kinds of lifting parts, and wherein quantity is maximum, technical requirement sternly and specification numerous and diverse be wire rope.The wire rope that the tower machine is used has by the function difference: hoist rope, variable-amplitude steel wire rope, jib stay cord, balance arm stay cord, dolly traction rope etc.The characteristics of wire rope are: the intensity of whole is high, and whole section is equally big or small, intensity is consistent, from heavy and light, can bear the vibrations load, elasticity is large, can be wound into dish, can be in balance exercise under high speed, and noiseless, after wearing and tearing, its crust can produce many burrs, is easy to find and is convenient to timely disposal.Wire rope is that 0.3～0.4mm finer wire is twisted into rope strand by one strand diameter usually, then is twisted rope by thigh.What the tower machine was used is ordinary lay, and characteristics are be difficult for loose and reverse.With regard to the rope strand cross sectional shape, high-building construction is the most suitable to adopt multiply not reverse wire rope with the tower machine, and this kind wire rope is made of same two-layer rope strand, two-layer rope strand twisting opposite direction, adopt the principle twisting of turning moment balance to form, when stressed, free end does not twist.The safety coefficient of tower crane lifting wire rope and variable-amplitude steel wire rope generally is taken as 5～6, and the safety coefficient of dolly traction rope and jib stay cord is taken as 3, and the dynamo-electric terraced halliard safety coefficient of tower must not be less than 10.The safety coefficient of wire rope is indispensable safety margin coefficient, and the maximum that never can rely on this safety margin face to improve without authorization wire rope allows charge of surety.Due to the importance of wire rope, must strengthen regularly the checking of wire rope comprehensively, be stored in the dry face sealing, have in the warehouse of timber floor or asphalt concrete surface, in order to avoid damaging surface is not wanted in corrosion during loading and unloading, to erect arrangement during stacking.Wire rope is carried out system to be lubricated and can improve serviceable life.But at present the traditional test lineoutofservice signal pull calculates according to pulley block ratio and pulley blocks efficient, calculates more complicated, and the pulling force that calculates and actual pulling force have certain discrepancy.
The utility model content
The purpose of this utility model is to provide the proving installation that a kind of tower crane is surveyed lineoutofservice signal pull, and this apparatus structure is simple, and test operation is easy, and test result is more accurate, more science.
The technical scheme that realizes the utility model purpose is: the utility model comprise successively pulley, tension arm, power sensor on to the opposite direction of pulley pressure at wire rope and be used for assurance power sensor be subjected to force direction with wire rope to the consistent counterweight clamping device of the pressure direction of pulley; Described counterweight clamping device comprises retained part, weight linear meter and counterweight; Described pulley is connected with tension arm, and tension arm is fixedly connected with an end of power sensor, and the other end of power sensor is fixedly connected with an end of weight linear meter, and the other end of weight linear meter is fixed with counterweight, and weight linear meter is provided with retained part.
Above-mentioned pulley and tension arm link together by split pin.
The utlity model has positive effect: (1) the utility model is simple in structure, and test operation is easy, and is practical; (2) the utility model has been simplified the computing method of lineoutofservice signal pull greatly, and test result is more accurate, more science.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1, the utility model comprises pulley 1, tension arm 2, power sensor 3 and the consistent counterweight clamping device 4 of pressure direction that is subjected to 5 pairs of pulleys 1 of force direction and wire rope that is used for assurance power sensor 3 successively on the opposite direction of 5 pairs of pulley 1 pressure of wire rope; Described counterweight clamping device 4 comprises retained part 41, weight linear meter 42 and counterweight 43; Described pulley 1 links together by split pin with tension arm 2, tension arm 2 is fixedly connected with an end of power sensor 3, the other end of power sensor 3 is fixedly connected with an end of weight linear meter 42, and the other end of weight linear meter 42 is fixed with counterweight 43, and weight linear meter 42 is provided with retained part 41.
When test, by retained part 41, whole device is fixed, pulley 1 is unloaded so that wire rope 5 passes between pulley 1 and tension arm 2; Whole device is drawn outward make 5 pairs of pulleys 1 of wire rope that a pressure be arranged, guarantee that by counterweight 43 pressure direction that is subjected to 5 pairs of pulleys 1 of force direction and wire rope of power sensor 3 is consistent; The power F that records by power sensor 3, and wire rope 5 and the angle [alpha] that pulley center forms calculate by computing formula N=F/cos α the power N that wire rope 5 is received.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
