Description
Technical field
The utility model relates to step-up system technical field, especially a kind of puller system step-up system.
Background technique
Currently, puller system mainly has decanter type and open type.Decanter type puller system is located among concrete melt pit, puller system
Stress building is undertaken by concrete, and structure is simple, but concrete melt pit length, width and height immobilize, and are tested the size-constrained of building.
Open type puller system is rest on the ground, and carries pulling force by longitudinal and cross beam, and structure is complicated, and the width generally constructed can be beyond drawing
The width of power machine, some puller system axial spacings are adjustable, adapted to the test of large scale building significantly.
The loading method of most of puller systems is hydraulic loaded.Tensile testing machine is generally divided into two parts, and a fixation has
It can also move integrally, other end is scalable oil cylinder.When test, building is separately fixed at both ends, and the contraction of telescopic oil cylinder carries out
Load test.
There is also following disadvantages for puller system in the prior art:
(1) load capability of current puller system not can increase.Existing puller system is all Straight pull, i.e., one end is liquid
Drawing mechanism is pressed, pull head can be moved, the other end is fixed pull head, pulls subject building, loading force by the retraction of hydraulic mechanism
Size place one's entire reliance upon hydraulic mechanism.And the load capability of hydraulic mechanism manufacture and design when it has been determined that in use process
In cannot change, therefore the load capability of puller system not can increase in use, for being more than the specified load capability of puller system
Test can not carry out.
(2) load capability declines puller system in use, and specified loading force is not achieved.In puller system use process,
With the aging and fatigue of hydraulic seal, the abrasion of piston and oil cylinder etc.；Oil temperature increases, the viscosity decline of hydraulic oil；It is hydraulic
The impurity of oil increases, the factors such as clogging hydraulic element and filter screen, so that the load capability of puller system declines, specified add is not achieved
Power is carried, causes the test that can be completed originally without can be carried out.
(3) Impact direction cannot change.Point-blank, direction of pull passes through two to current two pull heads of puller system
The line of pull head, direction are immutable.
(4) certain simple component tests need complex tool equipment instead to be tested the installation of component.
Utility model content
The applicant provides a kind of structurally reasonable puller system reinforcement dress for the disadvantage in above-mentioned existing production technology
It sets, to improve the load capability of puller system in the case where not carrying out any transformation to puller system, greatly improves using reliable
Property.
Technical solution used by the utility model is as follows:
A kind of puller system step-up system, including reinforcement portal frame, the structure of the reinforcement portal frame are as follows: be arranged including interval
Column, the bottom of the column fixed on the ground by foundation bolt, the front end face of two columns have it is multiple
The upstanding studs hole of even setting, the front end face middle position of two columns are installed the crossbeam of accumbency, are provided on the crossbeam multiple
Evenly spaced transom bolt hole；The outside of the crossbeam is equipped with piece boosting pull head component by fastening bolt and nut；Also wrap
Spaced two pull heads are included, reinforcement pulley gear is installed between two pull heads, one of pull head and reinforcement pulley fill
By static load wirerope installation subject component between setting, and locked at this pull head by fixed pin shaft, reinforcement pulley gear
End is provided with pulley, and winding wire ropes is since piece boosting pull head component successively around from the pulley to another pull head.
As a further improvement of the above technical scheme:
The structure of the reinforcement pulley gear are as follows: including partition, the both ends of the partition are separately installed with pulling plate, one end
Pulley is installed by pulley spindle on pulling plate, reinforcement pulley pin shaft is installed on the pulling plate of the other end.
The structure of the piece boosting pull head component are as follows: including pull head bottom plate, the upper and lower side of the pull head bottom plate has more
A pull head bolt hole, interval is equipped with two pieces of drawing ears disposed in parallel, two drawings ears middle parts on the front end face of the pull head bottom plate
It is provided with pin hole, piece boosting pull head pin shaft is installed between two pin holes.
The drawing ear is at trapezium structure.
The beneficial effects of the utility model are as follows:
The utility model is compact-sized, reasonable, easy to operate, by the way that step-up system is arranged between two pull heads, effectively
Increase puller system load capability, greatly improve use reliability.
Meanwhile the utility model is also equipped with following advantage:
1, in the case where existing puller system is not transformed, increase the load capability of puller system.The step-up system of single pulley
Pulling force can be increased and be twice, is i.e. F=2f, F are pulling force suffered by subject component, and f is puller system loading force.If in cloth on crossbeam
Fixed pulley is set, reinforcement pulley gear uses multiple movable pulleys, then pulling force F=nf suffered by component, and wherein n is multiplying power.
2, crossbeam facilitates the installation of subject component as pedestal.For the pulling force of the suspenders such as certain lifting lugs, hanging ring, bolt
Test, these components will be inherently bolted with other component, and in the utility model, these components can be directly installed on
On crossbeam, screwed bolt, lifting lug, hanging ring etc. can be directly threaded into the transom bolt hole of crossbeam, and the other end connects steel
Cord, steel wire can be around the piston rod for connecting oil cylinder after pulley, the reinforcement pulley pin shaft hole of pulling plate and the pin shafts for determining pull head 1
Hole alignment, fixed pin shaft is connected with reinforcement pulley pin shaft when being connected by pin shaft, or passing through wirerope, can also not have to reinforcement and fill
It sets, the direct one end of wirerope is connected in bolt, lifting lug, hanging ring etc., bypasses fixed pin shaft, and the other end is directly coupled to the piston of hydraulic cylinder
On bar.If it is have pedestal and bolt hole weldment, the pedestal of component can be installed on crossbeam by bolt, with
Above method pull test.
3, meet the load of different Impact directions.Since the transom bolt hole on crossbeam is evenly arranged, and on column 11
Upstanding studs hole is also the position for being evenly arranged, therefore being combined by changing piece boosting pull head, so that it may change tension point stress side
To Impact direction can be to change within the scope of 0~90O in principle.
4, in the case where not changing piston rod rated travel, increase elastic deformation amount's tolerance of component.Existing drawing
The pulling force stroke of power machine depends on the piston rod stroke l of pull action cylinder, when the tensile elasticity deflection of subject component is more than
The stroke l of piston rod, then test is unable to complete, because the flexible stroke of piston rod is before reaching the pulling force of requirement
It reaches the limit of, cannot be further continued for stretching, also can not just be further continued for loading.In the present invention, because there is reinforcement pulley gear
Presence, by reinforcement pulley gear opposite direction use, by elastic component be connected to piece boosting pull head combination and piece boosting pull head pin shaft, twine
It is connected to fixed pin shaft around one, wirerope, bypasses pulley, further around fixed pin shaft is crossed, the other end is fixed on the fixed pin of dynamic pull head
Axis, the flexible deformation tolerance of subject component in this way can be n times of the flexible stroke of piston rod, i.e. L=nl, n are multiplying power.
