Description
Technical Field
The invention relates to the technical field of liquefied petroleum gas steel cylinder conveying lines, in particular to a steel cylinder hydrostatic test water injection pipe position detection device.
Background
The intelligent rotary table type rapid detection line for the hydraulic pressure test of the liquefied petroleum gas steel cylinders developed by the company is identified as an international advanced level by domestic peer experts in 2015, and is initiated domestically. The problems found in the improved design are: before the steel bottle is moved to the bottle-down position occasionally, the water in the steel bottle is not discharged, so that the water injection pipe cannot be lifted, the rotary table is stopped immediately, and otherwise, mechanical accidents can occur.
Disclosure of Invention
The invention aims to overcome the defects of the technology and provide a water injection pipe position detection device for a steel cylinder hydrostatic test.
The invention adopts the following technical scheme to realize the aim:
the utility model provides a steel bottle hydrostatic test water injection pipe position detection device which characterized in that: the device comprises a pulling rod type travel switch, a position detection cylinder, a pneumatic reversing valve and a pneumatic pilot valve; the position detection cylinders are arranged on the inner side of the turntable, correspond to the water injection pipe lifting cylinders one by one, are equal in number, and synchronously move along with the rotation of the turntable; the pulling rod type travel switch is arranged on the ground, and the installation position is positioned at the previous station of the bottle-discharging position; the position detection cylinder and the water injection pipe lifting cylinder are connected in parallel in the same pneumatic loop and are sequentially connected with the pneumatic reversing valve and the pneumatic pilot valve.
Compared with the prior art, the invention has the beneficial effects that the on-site experiment verifies that when the steel bottle runs to the position before the bottle-discharging position, the water injection pipe is not lifted up because the water discharge is not completed, the position detection cylinder pulls the travel switch, and the position detection cylinder sends out an instruction, and the turntable immediately stops. The detection method and the device are arranged on the intelligent turntable type rapid detection line for the hydrostatic test of the liquefied petroleum gas steel cylinder, so that the normal operation of the turntable is effectively controlled, and the safety and the reliability of equipment are improved.

Detailed Description
The following detailed description of the invention refers to the accompanying drawings and preferred embodiments.
It will be understood that when an element is referred to as being "mounted" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items. The specific working principle of the present invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 1 and 2, a water injection pipe position detection device for a steel cylinder hydrostatic test consists of a position detection cylinder 3, a pull rod type travel switch 2, a pneumatic reversing valve 6 and a pneumatic pilot valve 7.
The position detection cylinders 3 are arranged on the inner side of the rotary table 1, are in one-to-one correspondence with the lifting cylinders 5 of the water injection pipes, and synchronously move along with the rotation of the rotary table 1. The pull rod type travel switch 2 is installed on the ground, and the installation position is located at the previous station of the bottle-discharging position.
The position detection cylinder 3 and the water injection pipe lifting cylinder 5 are connected in parallel in the same pneumatic circuit, when the pneumatic reversing main valve 6 is at the illustrated position, compressed air enters the lower parts of the two cylinders at the same time, and the cylinder rod ascends at the same time; when the pneumatic reversing main valve 6 reverses under the action of the pilot valve 7, compressed air enters the lower parts of the two cylinders simultaneously, and the cylinder rods extend out simultaneously. The position detection cylinder and the water injection pipe lifting cylinder always keep synchronous operation. In short, the position state of the cylinder rod of the position detection cylinder is identical to the position state of the cylinder rod of the water injection pipe lifting cylinder.
Before the steel bottle 8 runs to the bottle-discharging position, if the water in the bottle is not discharged, the water injection pipe 4 is still positioned in the steel bottle, and at the moment, the cylinder rod of the position detection cylinder 3 is positioned at the extending position, and the position detection cylinder can toggle the travel switch to send a signal to stop the rotary table from rotating, so that the occurrence of mechanical accidents is avoided. The position of the water injection pipe is judged by using a signal sent by the relative position relation between the cylinder rod of the position detection cylinder and the pulling rod type travel switch so as to determine whether the turntable is required to stop immediately.
The device has intelligent function, and can avoid mechanical accidents from happening accidentally.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
