Technical field
The utility model relates to a kind of tensioning equipment, specifically a kind of wind-powered electricity generation high strength crab-bolt tensioning equipment.
Background technology
Because wind-powered electricity generation high strength crab-bolt is used for blower foundation position fixation, so require very strict to the tensile strength of crab-bolt, in order to ensure that crab-bolt in use can not rupture, need stretch-draw crab-bolt being carried out to 100%.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, and drawing effect is good, and the wind-powered electricity generation high strength crab-bolt tensioning equipment that security performance is high.
For achieving the above object, the utility model provides following technical scheme:
A kind of wind-powered electricity generation high strength crab-bolt tensioning equipment, comprises supportive body, penetration type oil cylinder and hydraulic oil pump; Described penetration type oil cylinder is arranged on one end of supportive body, and the other end is provided with changeable type length extension device, and described penetration type oil cylinder and changeable type length extension device are in same level; The side of supportive body is provided with hydraulic oil pump, and penetration type oil cylinder is connected with hydraulic oil pump by two oil pipes.
As further program of the utility model: the two ends of described penetration type oil cylinder and changeable type length extension device are equipped with packing ring and nut.
As further program of the utility model: on the horizontal plane installing penetration type oil cylinder and changeable type length extension device, the middle part of supportive body is provided with three rollers uniformly.
As further program of the utility model: described elevating stage is installed on the supportive body below roller, and is provided with two, is placed in three rollers respectively between any two; The below of described two elevating stages is respectively equipped with oil cylinder.
Compared with prior art, the beneficial effects of the utility model are: the utility model wind-powered electricity generation high strength crab-bolt tensioning equipment, after the rolled thread of crab-bolt two ends terminates, crab-bolt is placed on elevating stage and then drop on roller, then crab-bolt one end is pushed through penetration type oil cylinder, to screw on again nut after cover upper gasket, the other end by nut screwing clamping on the end face of changeable type length extension device, according to specification and the performance rate of material, certain pulling force is applied to the two ends of crab-bolt and keeps the regular hour, to check whether crab-bolt can rupture, and nut can in the level and smooth rotation of threaded portion.This apparatus structure is simple, and easy to install and use, drawing effect is good, and intensity is large, and security performance is high; The research and development of this device, to the quality examination of crab-bolt, play very large castering action.
