Abstract
The utility model discloses a kind of food-through tension device, mainly including tensioning head, punching bar, bushing, pressure transducer, stretching rack, back-moving spring etc., it is characterised in that：Tensioning head is threaded connection with punching bar, and bushing is connected with punching bar, and punching bar end is provided with pressure transducer, and is locked by locking nut；Drive end bearing bracket is connected with bushing with rear end cap, and is fixed on stretching rack；Back-moving spring one end is acted on tensioning head, and the other end is acted on drive end bearing bracket；Oil-in and oil-out are integrated on stretching rack.This utility model adopts food-through tension structure, while oil-in and oil-out are integrated on stretching rack, efficiently reduces the volume of tensioning equipment；And by pressure transducer can effective detection stretching force in real time size, be greatly improved the efficiency and precision of tensioning.
Description
Technical field
This utility model belongs to deformed bar tensioning field of components, more particularly to a kind of food-through tension device.
Background technology
In the production process that pretensioning prestressed concrete makes track plates, the tensioning of deformed bar is extremely important
, but the tension force of deformed bar is very big, typically carries out tensioning to which using hydraulic test, but volume is more huge, receives
The factors such as space restriction, hydraulic test are difficult to arrange.Therefore design a kind of compact conformation, and being capable of effective detection stretching force in real time
The food-through tension device of size is necessary.
Utility model content
This utility model is to provide for a kind of compact conformation and is capable of the punching of effective detection stretching force size in real time
Tensioning equipment.
This utility model is achieved by the following technical solution：A kind of food-through tension device, it is characterised in that：Tensioning
Head（1）With punching bar（2）It is threaded connection, bushing（4）With punching bar（2）It is connected, punching bar（2）End is provided with pressure
Force transducer（6）, and pass through locking nut（7）Locked；Drive end bearing bracket（3）And rear end cap（5）With bushing（4）It is connected,
And it is fixed on stretching rack（9）On；Back-moving spring（8）One end acts on tensioning head（1）On, the other end acts on drive end bearing bracket（3）On；
Oil-in（9.1）And oil-out（9.2）It is integrated in stretching rack（9）On.
Implementing remarkable result of the present utility model is：This utility model adopts food-through tension structure, while by oil-in
It is integrated on stretching rack with oil-out, efficiently reduces the volume of tensioning equipment；And can be effective in real time by pressure transducer
The size of detection stretching force, is greatly improved the efficiency and precision of tensioning.
Below in conjunction with drawings and the embodiments, the utility model is described in further detail.
Description of the drawings
Fig. 1 is a kind of sectional view of food-through tension device of the present utility model.
In figure, 1- tensioning heads, 2- punching bars, 3- drive end bearing brackets, 4- bushings, 5- rear end caps, 6- pressure transducers, 7- locking screws
Mother, 8- back-moving springs, 9- stretching racks, 9.1- oil-ins, 9.2- oil-outs.
Specific embodiment
A kind of food-through tension device, it is characterised in that：Tensioning head（1）With punching bar（2）It is threaded connection, bushing
（4）With punching bar（2）It is connected, punching bar（2）End is provided with pressure transducer（6）, and pass through locking nut（7）Carry out
Locking；Drive end bearing bracket（3）And rear end cap（5）With bushing（4）It is connected, and is fixed on stretching rack（9）On；Back-moving spring（8）One
End acts on tensioning head（1）On, the other end acts on drive end bearing bracket（3）On；Oil-in（9.1）And oil-out（9.2）It is integrated in and opens
Try to stop people from fighting each other（9）On.
Real-time example one：A kind of food-through tension device is mainly used in the deformed bar tensioning of high-speed railway rail board assembly line
On station, tensioning head described in the utility model（1）Be connected by tensioning object, hydraulic oil is from oil-in（9.1）Into making lining
Set（4）Drive punching bar（2）Toward oil-out（9.2）Direction is moved, and then makes tensioning head（1）Drive by tensioning object of which movement, reach
To tensioning purpose.Back-moving spring in the process（8）Compressed, tensioning head can be made when oil circuit is unloaded（1）Recover initial position；
The pressure transducer in stretching process（6）Be capable of the size of effective detection stretching force in real time, be greatly improved tensioning efficiency and
Precision.
It is more than that one embodiment of the present utility model is described in detail, but the content is only of the present utility model
Preferred embodiment, it is impossible to be considered as limiting practical range of the present utility model.It is all to be made according to this utility model application range
Impartial change with improve etc., still all should belong within patent covering scope of the present utility model.
