Description
Technical field
The present invention relates to a kind of anti-misoperation apparatus for submersible pump cover pressure testing machine testing stand, belong to the mechanical skill of measurement
Art field.
Background technology
The operation order of submersible pump cover pressure testing machine testing stand is when submersible pump cover loading testing stand is tested, first
Oil hydraulic system is started, is held out against submersible pump cover with hydraulic cylinder, then carry out water flowing experiment；And by submersible pump cover from testing stand
When unloading, hydraulic pressure system should be first closed, oil hydraulic system is turned off, then again removes submersible pump cover.But worker is working
When tired or in the case that scatterbrained, it is easy to maloperation, it is likely that lead to submersible pump cover from testing stand
On fall, injure worker by a crashing object.
Invention content
The purpose of the present invention is overcoming defect of the existing technology, propose a kind of for the experiment of submersible pump cover pressure testing machine
The anti-misoperation apparatus of platform prevents operation mistake from threatening safety of workers.
The present invention adopts the following technical scheme that：A kind of anti-misoperation apparatus for submersible pump cover pressure testing machine testing stand,
It is characterised in that it includes ball valve, control crank, bracing wire, top transverse slat, iron sheet cover, the control crank is fixedly installed on described
On ball valve, the lower end of the control crank is connected by the bracing wire with the iron sheet cover, the iron sheet be provide be placed in it is described
The outside of top transverse slat.
Preferably, it is provided with square groove on the transverse slat of top.
Preferably, position corresponding with square groove is provided with circular pin on iron sheet cover, and the radial dimension of circular pin is less than etc.
In the width of square groove.
Preferably, the upper end of top transverse slat is provided with guide cylinder, for across bracing wire.
Preferably, winding drum is additionally provided between control crank and guide cylinder, for being convenient for receiving and dispatching bracing wire.
Preferably, circular through hole is provided on iron sheet cover, for lifting or putting down iron sheet cover across bracing wire.
The advantageous effect that the present invention is reached：The present invention pulls bracing wire to lift or put down iron sheet using control crank
Cover, to cover oil hydraulic system button, prevents worker's maloperation, has the advantages that simple in structure, safe and reliable, easy to use.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
The meaning marked in figure：1- ball valves, 2- control cranks, 3- bracing wires, 4- tops transverse slat, 5- iron sheet covers, 6- winding drums,
7- square grooves, 8- circular pins, 9- circular through holes, 10- guide cylinders.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and be not intended to limit the protection scope of the present invention and limit the scope of the invention.
Fig. 1 is the structure diagram of the present invention, and the present invention proposes a kind of for the anti-of submersible pump cover pressure testing machine testing stand
Misoperation apparatus, including ball valve 1, control crank 2, bracing wire 3, top transverse slat 4, iron sheet cover 5, control crank 2 is fixedly installed on ball
On valve 1, the lower end of control crank 2 is connected by bracing wire 3 with iron sheet cover 5, and iron sheet cover 5 is set to the outside of top transverse slat 4.
Square groove 7 is provided on top transverse slat 4；7 corresponding position of square groove is provided with circular pin 8 on iron sheet cover 5, circle
The radial dimension of shape bar 8 is less than or equal to the width of square groove 7.
The upper end of top transverse slat 4 is provided with guide cylinder 10, for across bracing wire 3；Between control crank 2 and guide cylinder 10 also
Winding drum 6 is provided with, for being convenient for receiving and dispatching bracing wire 3；Circular through hole 9 is provided on iron sheet cover 5, for lifting across bracing wire 3 or
Person puts down iron sheet cover 5.
The operation principle of the present invention：When submersible pump cover pressure testing machine carries out water flowing experiment, submersible pump cover is locked, this
When pull down control crank 2 and open hydraulic pressure system and carry out water flowing, while bracing wire 3 is pulled to lift and puts down iron sheet cover 5, operate oil pressure at any time
System button adjusts the coupling mechanism force of submersible pump cover；After the completion of water flowing experiment, when needing to remove submersible pump cover, pull-up is grasped at this time
Vertical handle 2 closes hydraulic pressure system, while bracing wire 3 is pulled to lift iron sheet cover 5, oil hydraulic system button is covered instead at this time, to take
Lower submersible pump cover must just pull down control crank 2 again, so ensure that worker's sequence operates.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
