Description
Technical field
The present invention relates to composite insulator detection field, more particularly to a kind of tensile testing machine lifting turnover device.
Background technology
Composite insulator is as insulator product of new generation, and its main body is generally protected by plug, the silica gel for being wrapped in mandrel outer
Set and cluster parachute and the gold utensil at two ends composition.Composite insulator is a kind of special insulation control, can be in overhead transmission line
Play an important role.Insulator is used for electric pole between one's early years, with the development of science and technology, being slowly developed in high-tension bus-bar connection tower
One end hung the insulators of many plate-likes, it is, in order to increase creep age distance, to be generally made up, just applaud of glass or ceramics
Edge.Insulator plays two basic roles in overhead transmission line, that is, supports wire and prevent electric current from going back to ground, the two works
With must be guaranteed, various electromechanical stress caused by insulator should not be changed due to environment and electric load condition and lose
Effect, otherwise insulator would not produce great effect, will damage use and the service life of whole piece circuit.
Power transmission sequence is widely used iron or aluminum metal-ware, is referred to as gold utensil.Gold utensil species is various, and purposes is each
It is different, for example, the various wire clamps of conducting wire, constitute the various links of insulator chain, the various aluminium hydraulic pressed connecting pipes of connecting wire, study for a second time courses one has flunked
Various types of conductor spacers on pipe, split conductor etc., lead in addition with all kinds of metal parts of pull wire of shaft tower, and as protection
The size of line is relevant, must work in coordination.Most of gold utensil needs to bear larger pulling force in operation, and what is had will also be while ensure
Electrically aspect contact is good, and it is related to the safety of wire or shaft tower, even if a damage, it is also possible to cause line fault.Cause
This, the quality of gold utensil, proper use of and installation have certain influence to the safe power transmission of circuit.
At present, in the production process of composite insulator, it is necessary to company between the two after plug is connected with gold utensil
Row tensile test is tapped into, traditional tensile test is all by manually composite insulator is carried on horizontal tensile testing machine
Pulling force between plug and gold utensil is tested.When being tested using above-mentioned this method, when being combined that needs are tested
When the length of insulator is long, when manually being carried, the trouble compared is, it is necessary to consume substantial amounts of manual labor；Its
It is secondary, generally all it is that the composite insulator of a batch is placed on transfer car(buggy) to be conveyed in test, and traditional turn
Car is transported in order to once convey more composite insulators, the design that both sides can be loaded then is used for transfer car(buggy), and
Because the length of composite insulator is longer, therefore, when carrying, the compound inslation close to the side of horizontal tensile testing machine
The more convenient handling of son, and then need the whole back track of whole transfer car(buggy) can enter luggage for the composite insulator of another side
Unload, the trouble compared.
The content of the invention
Turnover device is lifted by crane the technical problem to be solved in the present invention is to provide a kind of tensile testing machine, can be automatically to transhipment
Composite insulator on car is loaded and unloaded, and reduces artificial handling.
In order to solve the above technical problems, the technical scheme is that：A kind of tensile testing machine lifts by crane turnover device, and it is created
New point is：Tensile testing machine lifting turnover device is used to try the pulling force between the plug and gold utensil of composite insulator
Test, including
One test unit, the test unit includes a horizontally disposed horizontal tensile testing machine, in horizontal tensile testing machine
Upper end has the experiment groove that a composite insulator is put into；
One lifting unit, the lifting unit includes a pair of lifting dragons installed in the long axis direction side of horizontal tensile testing machine
Door frame, the two ends of the hoisting gantry frame are located at the two ends of horizontal tensile testing machine respectively, between two hoisting gantry frames also
A crossbeam is provided with, long axis direction extension of the crossbeam along composite insulator is connected with several arranged side by side points in the lower end of crossbeam
The suspension hook of cloth, the crossbeam is driven in the horizontal direction by a drive mechanism and vertical direction is moved back and forth；
One turnover unit, the turnover unit includes a tote cart for being arranged on hoisting gantry frame lower end.
Further, the drive mechanism includes the monorail trolley being separately mounted on two hoisting gantry frames for a pair,
An electric block is also equipped with monorail trolley, the lower end of the electric block is connected with crossbeam.
Further, the tote cart includes
One turnover vehicle frame, the turnover vehicle frame is by horizontally disposed base portion and vertically disposed revolving bracket installation portion two
It is grouped into, the base portion and revolving bracket installation portion are in square frame shape, and revolving bracket installation position is in the middle position of base portion
Put；
Turnover wheel installed in the bottom of base portion, turnover wheel has had four altogether, respectively positioned at four corner angle of base portion,
The adjacent turnover wheel of two of which is preceding turnover wheel, uses universal wheel, and two other turnover wheel is rear tote cart
Wheel, uses directional wheel；
Ordered series of numbers is arranged on the revolving bracket of the both sides of the front end of revolving bracket installation portion and the both sides of rear end, positioned at revolving bracket
The revolving bracket two of the same side of installation portion is that one group of composition plug puts revolving bracket, and the revolving bracket is away from turnover branch
One end of frame installation portion is gradually inclined upwardly；
One is arranged on the hand that asks in week of the front end of revolving bracket installation portion, and the hand that asks in the week is pacified by connecting rod and revolving bracket
Dress portion is connected.
Further, the one end of the revolving bracket away from revolving bracket installation portion is set with rubber protecting case.
The advantage of the invention is that：In the present invention, by setting up a pair of hoisting gantry frames on horizontal tensile testing machine,
And by the cooperation between crossbeam, suspension hook and drive mechanism, so as to can realize composite insulator in tote cart and horizontal pulling force
The handling back and forth of testing machine, so that artificial carrying is reduced, moreover, by the lifting of crossbeam, may be implemented in the both sides of tote cart
Move back and forth, the handling to the insulator on tote cart both sides can be achieved in the steering without tote cart, very convenient.
For the setting of drive mechanism, using the setting of monorail trolley, so that crossbeam in the horizontal direction reciprocal can be realized
It is mobile, and the setting of electric block, then crossbeam moving back and forth in vertical direction is realized, so as to realize composite insulator
Handling provides good basis.
And for the design of transfer car(buggy), plug is placed in plug and put on revolving bracket by staff successively, wait to put
Man Hou, directly by a staff is dilatory just can be labour to be saved, while operating efficiency is improved；In addition, in turnover
Protective case is set with support, it is to avoid staff is abraded by revolving bracket when putting plug.
