Abstract
A guyrope of a center hole jack comprises a rope connected between a gantry and ground; the rope is a steel strand; the upper end of the steel strand is anchored with an upper anchoring connector, and the top of the upper anchoring connector is provided with two articulation claws which are respectively articulated with an anchoring plate on the gantry through hinged shafts; the inner part of the upper anchoring connector is connected with the steel strand through a guiding plate; the lower end of the steel strand is anchored and connected with a hydraulic center hole jack; an oil cylinder of the hydraulic center hole jack is provided with a pressure meter; the hydraulic center hole jack is fixed inside a ground-anchor connector; the oil cylinder of the hydraulic center hole jack is connected with a hydraulic pumping station through a high-pressure oil pipeline; and the bottom of the ground-anchor connector is articulated with an anchoring ear-plate on ground. The utility model utilizes the steel strand and the guyrope of the center hole jack, and adopts the pressure meter of the oil cylinder to indicate actual stress so as to overcome the technical problem that the indistinctness of the actual stress of the guyrope results in the conditions that the guyrope can not be tensioned and masts sway.
Description
Technical field
The utility model relates to a kind of crane mast lifting cable wind rope.
Background technology
Cable wind rope is China's instrument that the thirties in last century, routine was used in the main equipment lifting always so far, and existing cable wind rope is with the supporting cable wind ropes that are provided with such as steel rope, polyspast, shackle and winch that calculated diameter.The shortcoming of this method is: can not see clearly whether every cable wind rope actual loading meets or exceeds the pulling force that calculates institute's palpus.Can only estimate by rule of thumb that this often greatly differs from each other with actual.The steel rope pulling cable wind rope draws not tightly in addition, because self gravitation influence generally all will have a winding degree, the mast that makes like this rocks very big under wind action, and particularly the mast top is rocked very big.
The utility model content
The utility model provides a kind of pulling cable wind rope for through type jack, and it is indeterminate to solve the true stressing conditions of existing cable rope, and it is not tight to cause cable rope to draw, the technical matters that mast rocks.
The technical scheme that its technical matters that solves the utility model adopts is:
This pulling cable wind rope for through type jack, comprise the hawser that is connected between a shape pylon and the ground, it is characterized in that: above-mentioned hawser is steel strand, the upper end of steel strand and last anchor connector grappling, two hinge finger are arranged at the top of last anchor connector, hinge finger is hinged with the anchor plate on the door shape pylon by hinge, the inside of last anchor connector is connected with steel strand by the comb guide plate, steel strand lower end and the anchor connection of hydraulic pressure feedthrough jack, have compression indicator on the oil cylinder of hydraulic pressure feedthrough jack, hydraulic pressure feedthrough jack is fixed in anchor connector inside, ground, the oil cylinder of hydraulic pressure feedthrough jack is connected with hydraulic power unit through high pressure fuel pipe, and the bottom of ground anchor connector and ground anchoring otic placode are hinged.
The beneficial effects of the utility model are as follows:
The utility model has utilized steel strand and jack to draw guy.Two ends are connected with last anchor connector by the ground anchor connector, and it is tight that cable rope draws, and avoided mast to rock.The actual loading that can reflect it by the compression indicator of oil cylinder, the stressed of calculation requirement can be found out at any time like this, and the pulling force of steel strand is greater than steel rope, its deadweight is light again, the steel strand safety lift heavy of a Φ 15.24 is 12t, the steel rope safety lift heavy of a Φ 65 is 42t, therefore with 4 steel strand just greater than the pull of steel wire of Φ 65.So used hollow jack, power and cost greatly can lighten one's labor.
The utility model can be widely used in ship building industry, oil, chemical industry, offshore production platform, is particularly suitable for super-huge steel structure hoisting construction.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the enlarged drawing at Figure 1A place.
Among the figure, the 1-hydraulic power unit, the 2-high pressure fuel pipe, 3-hydraulic pressure feedthrough jack, the 4-compression indicator, 5-ground anchor connector, 6-anchoring otic placode, the 7-steel strand, the last anchor attaching parts of 8-, 9-hinge finger, 10-hinge, 11-comb guide plate.
The specific embodiment
Embodiment is referring to shown in Figure 1, this pulling cable wind rope for through type jack, comprise the hawser that is connected between a shape pylon and the ground, above-mentioned hawser is steel strand 7, the upper end of steel strand and 8 grapplings of last anchor connector, referring to shown in Figure 2, two hinge finger 9 are arranged at the top of last anchor connector, hinge finger is hinged with the anchor plate on the door shape pylon by hinge 10, the inside of last anchor connector 8 is connected with steel strand by comb guide plate 11, steel strand 7 lower ends and 3 anchor connections of hydraulic pressure feedthrough jack, have compression indicator 4 on the oil cylinder of hydraulic pressure feedthrough jack 3, hydraulic pressure feedthrough jack 3 is fixed in anchor connector 5 inside, ground, and the oil cylinder of hydraulic pressure feedthrough jack 3 is connected with hydraulic power unit 1 through high pressure fuel pipe 2, and the bottom of ground anchor connector and ground anchoring otic placode 6 are hinged.
