[0002] In the chemical industry, strong acids mainly refer to permanganate, hydrochloric acid, sulfuric acid, nitric acid, perchloric acid, selenic acid, hydrobromic acid, hydroiodic acid, and chloric acid. Among them, perchloric acid, hydroiodic acid, hydrobromic acid, hydrochloric acid (hydrochloric acid), sulfuric acid, and nitric acid are collectively referred to as the six major inorganic strong acids. They all have strong irritation and corrosion effects, and human contact can cause serious burns. It is advisable to rinse with water or soda water. When loading liquid strong acids in tank trucks or train tank trucks, crane pipes are often used for loading. The crane pipe column is installed on the upper part of the loading station and driven by an automatic positioning device. A branch pipeline is set at the loading position of the main material pipeline, and a flow meter and valve are arranged. The branch pipeline is connected to the feed port of the crane pipe.

One end of the horizontal plate 13 is slidably connected to the limiting rod 12. Due to the limitation of the horizontal plate 13 by the limiting rod 12, when the one-way screw rod 10 rotates, the horizontal plate 13 can be driven to move horizontally through the threaded screw sleeve 11.

[0054] In this embodiment, the second positioning mechanism is arranged on the pushing seat 2 and is used to drive the crane pipe body 5. The second positioning mechanism includes a driving seat 17 fixedly installed at the bottom of the horizontal plate 13. A positioning motor 14 is fixedly connected to one side of the driving seat 17.

A rubber ball 31 is provided at one end of the rubber rod 30. The rubber ball 31 cooperates with the crane tube body 5. When the rubber ball 31 rotates and contacts the crane tube body 5, the crane tube body 5 can be knocked, thereby promoting the flow rate of the liquid on the inner wall of the crane tube body 5. The rubber ball 31 is made of rubber material and has the effect of reducing noise.

[0057] In this embodiment, the recovery mechanism is arranged below the push seat 2 and is used to recycle the residual liquid on the inner wall of the crane tube body 5. The recovery mechanism includes a rotating motor 32 fixedly installed on the top of the push seat 2. The bottom of the push seat 2 is rotatably connected to a drive shaft 33.

The bottom of the push seat 2 is rotatably connected to a passive rotating rod 35. The outer wall of the passive rotating rod 35 is fixedly connected to the drive gear. 34 meshed with a passive gear 36, the bottom end of the passive rotating rod 35 is fixedly connected with an extension plate 37, one end of the extension plate 37 is fixedly connected with a liquid collecting cylinder 38, a plurality of guide grooves are arranged on the inner wall of the crane tube body 5, and a guide rubber shell 50 is arranged in each of the plurality of guide grooves. The guide rubber shell 50 is made of fluororubber and is resistant to strong acid. A drain pipe 51 is arranged at the bottom of the liquid collecting cylinder 38, and a valve 52 is arranged on the drain pipe 51. By opening the valve 52, the strong acid liquid collected in the liquid collecting cylinder 38 can be discharged through the drain pipe 51.

[0058] In this embodiment, pillars 53 are fixedly installed at the four corners of the bottom of the positioning frame 1, and two reinforcement plates 54 are fixedly connected between the four pillars 53. The two reinforcement plates 54 can reinforce the four pillars 53, thereby improving the stability of the device. The bottom end of the pillar 53 is fixedly connected to a mounting plate 55, and the mounting plate 55 is provided with mounting screws 56. The mounting plate 55 fixedly connected to the pillar 53 is fixed on the strong acid loading platform using the mounting screws 56.

[0059] The implementation principle of the automatic positioning device for the crane pipe of a strong acid loading truck in the embodiment of the present application is as follows: first, the mounting plate 55 fixedly connected to the support 53 is fixed to the strong acid loading platform by means of the mounting screws 56, the strong acid truck is stopped under the loading platform, the liquid inlet of the strong acid truck is opened, and the positioning motor 19 is started to rotate the one-way screw rod 10. Due to the horizontal limit of the horizontal plate 13 by the limit rod 12, the screw sleeve 11 threadedly connected to the one-way screw rod 10 can drive the horizontal plate 13 to move horizontally, and the horizontal plate 13 drives the driving seat 17 to move, thereby adjusting the lateral position of the crane pipe body 5 and the strong acid truck, so that the crane pipe body 5 and the liquid inlet of the strong acid truck are located on the horizontal line, and then the positioning motor 14 is started to rotate the one-way screw rod 15. Due to the two limit rods The horizontal limit of the convex plate 16 is 18, so that the one-way screw rod 15 drives the convex plate 16 to move linearly, and the convex plate 16 drives the push seat 2, so that the crane tube body 5 is moved above the liquid inlet of the strong acid vehicle, thereby achieving the effect of automatic positioning. Since the lower part of the crane tube body 5 is retractable, the electric push rod 8 can be used to drive the splash cover 6 to move downward, so that the crane tube body 5 is inserted into the liquid inlet of the strong acid vehicle, and the strong acid liquid can be transported to the strong acid vehicle through the crane tube body 5. After the transportation is completed, the electric push rod 8 is used to drive the splash cover 6 to separate from the liquid inlet of the strong acid vehicle, and at the same time, the rotating motor 32 is started, so that the driving shaft 33 drives the driving gear 34 to rotate. Due to the meshing between the driving gear 34 and the passive gear 36, the passive gear 36 drives the passive rotating rod 35 to rotate. The passive rotating rod 35 drives the liquid collecting cylinder 38 to rotate to the bottom of the crane tube body 5 through the fixedly connected extension plate 37 and aligns it vertically, and starts the driving motor 19, so that the driving rod 21 drives the cam 22 to rotate. Since the cam 22 contacts the bottom of the stabilizing plate 25, the cam 22 squeezes the stabilizing plate 25 to move upward along the two vertical rods 23 when rotating, and compresses the two reset springs 24. When the two reset springs 24 release their elastic force, they can drive the stabilizing plate 25 to reset and achieve the effect of up and down reciprocating movement. The elastic force of the two reset springs 24 is used to make the stabilizing plate 25 drive the crane tube body 5 to shake up and down, and cooperate with the guide rubber shell 50 on the inner wall of the crane tube body 5. The guide rubber shell 50 is made of fluororubber, which is a high-performance acid and alkali resistant material. The material contains fluorine, so it has excellent chemical corrosion resistance and high temperature stability, and can resist the erosion of most chemical solvents and strong acids, so that the residual liquid on the inner wall of the crane tube body 5 slides out and flows into the liquid collecting cylinder 38 below for collection. At the same time, the driving rod 21 can drive the meshing second bevel gear 28 to rotate through the fixedly connected first bevel gear 26, and the second bevel gear 28 drives the rotating rod 27 to rotate, and the rotating rod 27 drives the rotating plate 29 to rotate, and the rotating plate 29 drives the rubber rod 30 to rotate, and the rubber rod 30 drives the rubber ball 31 to rotate, and reciprocates to knock on the crane tube body 5, thereby accelerating the flow rate of the residual liquid on the inner wall of the crane tube body 5 and improving the recovery rate. The whole device is connected to a power supply and a main control button, which is controlled by the main control button.Since the device matched with the control button is a common device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described here.

A sealing sleeve 42 is provided at the bottom of the liquid collecting cylinder 38, and a stirring rod 43 is rotatably provided in the sealing sleeve 42. The stirring rod 43 is fixedly connected to the output shaft of the stirring motor 41, and a sleeve plate 44 is fixedly connected to the stirring rod 43, and a stirring blade 45 is fixedly connected to the sleeve plate 44. A circular sleeve is fixedly connected to the stirring rod 43, and a connecting rod 46 is fixedly connected to the circular sleeve. One end of the connecting rod 46 is fixedly connected to a scraper 47, and the scraper 47 contacts the inner wall of the liquid collecting cylinder 38. A filter plate 48 is provided in the liquid collecting cylinder 38, and the filter plate 48 is located in the liquid collecting cylinder 38. Two guide plates 49 are symmetrically arranged above 48. When the strong acid liquid drips onto the two guide plates 49 in the liquid collecting barrel 38, the two guide plates 49 can guide the strong acid liquid to the filter plate 48 for filtration. The stirring motor 41 is started, so that the stirring rod 43 drives the sleeve plate 44 to rotate, and the sleeve plate 44 drives the stirring blades 45 to rotate to stir the strong acid liquid, thereby avoiding the precipitation of the strong acid liquid. At the same time, the circular sleeve fixedly connected to the stirring rod 43 rotates, and the circular sleeve drives the scraper 47 to rotate through the connecting rod 46 to scrape off the liquid attached to the inner wall of the liquid collecting barrel 38, which is beneficial to the subsequent cleaning of the inner wall of the liquid collecting barrel 38. All structures in this application can be selected in terms of material and length according to actual usage.
