Abstract
Card jack before a kind of intelligence being easily installed and safeguarding of being easy to construct, including jack cylinder and piston, described jack cylinder is two-way cylinder, it is connected with cylinder body one end and has seal plug and support tube, described support tube is the outwardly directed cylinder with holes of undergauge structure, one end of described piston is the outwardly directed cylinder with holes of undergauge structure, and the cylinder with holes of described piston is socketed on the endoporus of the overhanging bore with holes of support tube through seal plug.Its advantage is just to carry out stretching construction, simple in construction, convenient operation and control only with a jack, and jack front end external diameter is less, solves the prestressed stretch-draw difficult problem having space to limit；Front card moveable anchor is arranged on jack front end, saves stretching construction prestress wire；Simple in construction is easily installed and safeguards；Digital display elongation value of stretching in real time.
Description
Technical field
The present invention relates to relate to the jack in prestressing force applied technical field, be easy to construction particularly to one and be prone to peace
Dress card jack front with the intelligence safeguarded.
Background technology
The applicant applied for a Chinese patent, Application No.: 2015203097969 entitled " be easy to the intelligence of construction
Clip type jack before can ", piston is cancelled in this patent application, backhaul oil cylinder, stretch-draw oil cylinder drive punching set mobile respectively, it is achieved
Stretch-draw, saves clip type jack before the intelligence being easy to construction of steel strand wires, has also reached preferable using effect, but, due to
The piston that this structure is cancelled, therefore, needs the collaborative use of backhaul oil cylinder, stretch-draw oil cylinder two, attached Hydraulic system and control system
System is just relative complex, and much structure is complicated, and cost is high, controls difficulty again big.
Summary of the invention
It is an object of the invention to provide a kind of jack front end external diameter less, solve the prestressed stretch-draw having space to limit
A difficult problem；Front card moveable anchor is arranged on jack front end, saves stretching construction prestress wire；Simple in construction be easily installed with
Safeguard；The in real time card jack before the intelligence being easily installed and safeguarding of being easy to construct of digital display elongation value of stretching.
The solution of the present invention is such that
A kind of front card jack of the intelligence being easily installed and safeguarding of constructing of being easy to, including jack cylinder and piston, described
Jack cylinder is two-way cylinder, and being connected with cylinder body one end has seal plug and support tube, and described support tube is undergauge knot
The outwardly directed cylinder with holes of structure, one end of described piston is the outwardly directed cylinder with holes of undergauge structure, the band of described piston
Hole cylinder is socketed on the endoporus of the overhanging bore with holes of support tube through seal plug,
More specifically technical scheme also includes: described support tube front end is fixedly connected with the baffle plate of band through hole, described piston
Front end endoporus is provided with front card device；The side of described top board is withstood on rear side of baffle plate.
It is an advantage of the invention that and just can carry out stretching construction only with a jack, simple in construction, convenient operation and control,
Jack front end external diameter is less, solves the prestressed stretch-draw difficult problem having space to limit；Front card moveable anchor is arranged on jack front end,
Save stretching construction prestress wire；Simple in construction is easily installed and safeguards；Digital display elongation value of stretching in real time.
Accompanying drawing explanation
Fig. 1 is embodiments of the invention.
Detailed description of the invention
As it is shown in figure 1, the present embodiment includes jack cylinder 2 and piston 3, described jack cylinder 2 is for possessing oil return opening
A, the two-way cylinder of oil-in B, piston 3 two ends stretch out cylinder body respectively, and its left end extending area connects displacement transducer group
Part 1, by displacement sensor component real-time digital display elongation value of stretching；Connect at the jack cylinder 2 cylinder body other end and have seal plug 4
With support tube 5, described support tube 5 is the outwardly directed cylinder with holes of undergauge structure, and described piston 3 external part to the right is undergauge
The outwardly directed cylinder with holes of structure, the cylinder with holes of described piston 3 is socketed on, through seal plug 4, the band that support tube 5 is overhanging
The endoporus of hole bore,
Described support tube 5 front end is fixedly connected with the baffle plate 15 of band through hole, and before described piston 3 front end endoporus is provided with, card fills
Put；The side of described top board 14 is withstood on rear side of baffle plate 15.
Front card device include depression bar 6, pressing plate 7, spring 8, location-plate 9, push rod 10, intermediate plate 11, anchor slab 12, fairlead 13,
Top board 14.
