Description
Technical field
The invention belongs to electronic scale weighing technology fields, particularly relate to a kind of novel drawing of hang hook steelyard calibrating
Head.
Background technique
Hang hook steelyard is widely used in heavy-duty machinery, logistic storage, port and pier handling and weighing, as economy and society are sent out
Exhibition, big scale hook scale (10t, 30t, 50t, 100t etc.) application is more and more, according to traditional dead weight type safe principle, passes through hanging
Counterweight carries out calibrating and has been no longer appropriate for big scale hook scale.Currently, dead weight/superimposion formula hang hook steelyard calibrating installation solves
Problem is stated, it can be achieved that wide range is then using superposition in the calibrating of small scale hook scale using dead weight type safe principle (load of hanging counterweight)
Formula force standard machines (hydraulic loaded) have the advantage that detection range is wide, precision is high, manufacturing cost is low.
In the past, dead weight/matching used pull head of superimposion formula hang hook steelyard calibrating installation only included U-shaped connector, bolt,
This pull head is not suitable for the calibrating of multiple structural forms hang hook steelyard, and especially such pull head and hang hook steelyard calibrating installation belong to firmly
Connection, during examining and determine small scale hook scale, it may appear that hang hook steelyard tension direction pulls to power axis with calibrating installation and is not overlapped
The case where, and the error that introduces of such case is extremely easy to cause and causes the calibrating of small scale hook scale unqualified.If according to hanging
The case where hook scale, replaces pull head, and installment work causes high effort for, is cumbersome.
Summary of the invention
To solve the problems mentioned above in the background art, the purpose of the present invention is to provide a kind of calibratings of hang hook steelyard with newly
Type pull head.
To achieve the above object, the technical scheme adopted by the invention is as follows:

Part；Each U-shaped connector open end is inserted with first bolt, and each U-shaped connector closed end is worn
There is a center sunpender, each center sunpender one end is fixed on hang hook steelyard calibrating installation, and the other end passes through in contrast
In the U-shaped connector answered and the intermediate connector being plugged in corresponding U-shaped connector, connect in each centre
It is additionally provided with a bow shackle on fitting, each bow shackle, which passes through second bolt and is fixed on, to be corresponded
Intermediate connector, and each bow shackle connects using corresponding second bolt as swinging axle in corresponding centre
It is swung on fitting.
In above-mentioned technical proposal, the U-shaped connector and intermediate connector of each pull head are the same as corresponding center
Sunpender is threadedly coupled.
In above-mentioned technical proposal, be equipped with conical socket among each first bolt, for hang hook steelyard installation when pair
In.
In above-mentioned technical proposal, on each pull head, the intermediate connector is in U-shaped connector and the first bolt institute
In the cavity surrounded, and end and first bolt of the intermediate connector equipped with second bolt one end are close to intermediate connector one
The distance of side is at least 10cm.
The present invention is directed to the characteristics of dead weight/superimposion formula force standard machines, according to hang hook steelyard structure type and can weigh model
The difference enclosed selects different to pull to test connection type.When examining and determine small scale hook scale, arch hanging ring is selected to carry out the company of pulling to
It connects, due to the movable property of the freedom of this pull head form, be conducive to hang hook steelyard and calibrating installation pulls to centering, ensure that small title
Measure the accuracy of hang hook steelyard calibrating indicating value.
When examining and determine big scale hook scale, U-shaped connector and the first bolt is selected to carry out pulling to connection, this pull head form energy
Larger pulling force is born, ensure that safety when hang hook steelyard tension, and is larger for big scale hook scale size and examine and determine dress
Limited situation between emptying needs suspension hook and hanging ring on removal hang hook steelyard to carry out calibrating, and this form that pulls to can also be with suspension hook
Scale main body forms effective connection.
Compared with prior art, the beneficial effects of the present invention are:
1, the present invention has taken into account the characteristics of dead weight/superimposion formula force standard machines, can be according to hang hook steelyard structure type and title
The difference for measuring range, select it is different pull to test connection type, have the characteristics that applied widely, calibrating efficiency is high.
2, when small-range hang hook steelyard is examined and determine, pass through arch hanging ring connecting shackle scale, it is ensured that it pulls to neutral good, so that
Test result is more accurate and reliable.
3, when wide range hang hook steelyard is examined and determine, U-shaped connector and the first bolt carry out pulling to connection, can bear larger pulling force,
It ensure that safety when hang hook steelyard tension；At the same time, conical socket is equipped among the first bolt, when for hang hook steelyard installation
Centering, so that test result is more accurate and reliable.
