Abstract
The invention provides a strength detecting tool for a welded assembly of a top cover of a lifting machine. The strength detecting tool comprises a tool base, an air cylinder support, an air cylinder locating seat and an air cylinder, wherein the air cylinder support and the air cylinder locating seat are arranged on the tool base, the air cylinder is arranged on the air cylinder support and located and fixed by the air cylinder locating seat, the air cylinder is connected with one end of a steel wire rope through a connecting frame, the other end of the steel wire rope bypasses a steel wire rope wheel to be fixed on a steel wire rope locking plate on the tool base, the steel wire rope wheel sleeves a small shaft of the tested top cover, the tested top cover is clamped and fixed with a top cover support through a quick clamper installed on the tool base, a hand-operated air valve is arranged on the tool base, and the hand-operated air valve and the air cylinder form a loop through a compressed air pipe. The strength detecting tool for the welded assembly of the top cover of the lifting machine uses the large air cylinder to drive the steel wire rope wheel to act on the small shaft, uses a pressure meter to display pressure, can conveniently, effectively and accurately test the welding strength of the small shaft of the double-column top cover in 1.5ton pressure, avoids unqualified products and prevents safety hazards.
Description
Technical field
The present invention relates to the lifting machine field, relate in particular to the little axle welding structural element of a kind of double-column lifting machine cap intensity detection frock.
Background technology
Double-column lifter is the product that Shanghai Yuan Zheng company kind is maximum, output is maximum, double-column lifting machine cap weldment is connected by plug welding in a week with axillare by little axle, little axle connects the slide unit trailing arm by wire rope, serious security incident must, by little axle transmission, can occur once sealing-off causes little axle to come off in the lifting machine load.This is the crucial qualifying point of double-column lifter, owing to being difficult for finding weld defects after top cover weldment postwelding and spraying, needs badly and the little axle strength of joint of top cover is made to a tensile test goes wrong with prevention, in avoiding using.
Summary of the invention
The object of the present invention is to provide a kind of lifting machine top cover weld assembly intensity detection frock, in order to detect lifting machine top cover, little axle weld strength.
The objective of the invention is to be achieved through the following technical solutions.
A kind of lifting machine top cover weld assembly intensity detection frock, comprise: the frock pedestal, be arranged on cylinder saddle and cylinder positioning seat on the frock pedestal, place a cylinder fixing by cylinder positioning seat location on cylinder saddle, cylinder is connected with wire rope one end by connection box, the wire rope other end is walked around wire rope pulley and is fixed on the wire rope locking plate on the frock pedestal, wire rope pulley is sleeved on the little axle of test top cover, the test top cover is fixedly clamped by quick clamp device and the top cover support seat be arranged on the frock pedestal, be provided with hand and pull air valve on the frock pedestal, hand is pulled air valve and is formed a loop by compressed air hose and cylinder.
Further preferably, also comprise oil and water filters, oil and water filters one termination pressurized air, the compressed air hose catcher of the other end is pulled air valve.
Further preferably, by two cylinder anchor ears, cylinder is fixed on cylinder saddle.
Further preferably, on described frock pedestal, also be provided with safety guard, it covers on connection box and wire rope locking plate, occurs security incident while preventing from testing.
The present invention compared with prior art, beneficial effect is: lifting machine top cover weld assembly intensity detection frock provided by the invention, driving wire rope pulley by large cylinder acts on little axle, show pressure by tensimeter, can test easily and effectively, accurately the little axle weld strength of twin columns top cover under 1.5 tons of pressure, avoid unacceptable product to occur, prevent that potential safety hazard from occurring.
The accompanying drawing explanation
Fig. 1 is lifting machine top cover weld assembly intensity detection tool structure figure of the present invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to shown in Fig. 1, lifting machine top cover weld assembly intensity detection frock of the present invention comprises: frock pedestal 1, be arranged on cylinder saddle 2 on frock pedestal 1 and cylinder positioning seat 5, cylinder saddle 2 and place a cylinder 3 fixing by cylinder positioning seat 5 location,
Further, by two cylinder anchor ears 4, cylinder 3 is fixed on cylinder saddle 2.
Further, also be provided with safety guard 13 on frock pedestal 1, it covers on connection box 7 and wire rope locking plate 9.
Be provided with hand and pull air valve 14, oil and water filters 15 on frock pedestal 1, oil and water filters 15 1 termination compressed air hoses 17, compressed air hose 16 catchers of the other end are pulled air valve 14.Hand is pulled air valve 14 and is formed a loop by compressed air hose 16 and cylinder 3.
During use, by quick clamp device, hold out against cap assembly on the top cover support seat, then pull when hand is pulled air valve to gauge hand 0.5Mp and unclamp air valve.Finally unload the workpiece cap assembly, check that there is flawless commissure or snaps, workpiece has or not distortion, if not then can judge qualified.
Because being uses the pneumatic means such as cylinder, can move and detect efficiently little axle weld strength, rain glass can show force value constantly, guarantees to detect accurately little axle intensity under 1.5 tons of pressure.Cylinder piston max die travel distance 140mm, guarantee that steel wire rope looseness can easily be enclosed within on wire rope pulley fast.Need only 20 seconds left and right time so detect a workpiece, convenient and swift.
Lifting machine top cover weld assembly intensity detection frock provided by the invention, driving wire rope pulley by large cylinder acts on little axle, show pressure by tensimeter, can test easily and effectively, accurately the little axle weld strength of twin columns top cover under 1.5 tons of pressure, avoid unacceptable product to occur, prevent that potential safety hazard from occurring.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
