DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and examples.

[0025] In order to solve the technical problems mentioned in the background technology, Figure 1 -Attached Figure 7 A sulfuric acid automatic filling and loading equipment includes a positioning platform 100. A storage space for a transport vehicle 200 is provided at the lower end of the positioning platform 100. The storage space can accommodate multiple transport vehicles 200 for filling sulfuric acid simultaneously or successively. A filling device is provided in the positioning platform 100, and the sulfuric acid in the storage tank is introduced into the transport vehicle 200 through the filling device.

[0026] Specifically; the filling equipment includes a filling device 600, the filling device 600 includes a conveying pipe group, the end of the conveying pipe group is connected to a conveying joint 650, and the lower end of the conveying joint 650 is provided with a conveying opening 651 adapted to the transport vehicle 200, and the filling equipment also includes a driving component 300 for driving the conveying joint 650 to move. The driving component 300 can drive the conveying joint 650 to different positions, and control the conveying joint 650 to be relative to and pressed with the filling port 210 at the upper end of the transport vehicle 200 to achieve accurate docking between the two. The end of the conveying pipe group is connected to the conveying joint 650, and the sulfuric acid in the storage tank can be pumped into the conveying joint 650 along the conveying pipe group, and finally discharged from the conveying opening 651 at the lower end into the transport vehicle 200 to achieve filling and loading.

[0027] The conveying pipe group here includes a relatively fixed filling positioning pipe 610, a relatively movable filling displacement pipe 620 and a movable communicating device 630 located between the filling positioning pipe 610 and the filling displacement pipe 620. The movable communicating device 630 can be in a movable connected state. The filling positioning pipe 610 is fixed to the positioning platform 100 through the pipe positioning frame 640 to ensure the stability of this side. The end of the filling displacement pipe 620 is connected to the conveying joint 650 and can move arbitrarily with the conveying joint 650. It can move to any position according to the parking position of the transport vehicle 200 to ensure the accuracy of sulfuric acid filling.

[0028] Furthermore, a positioning assembly 500 and a deflection assembly 400 are provided between the drive assembly 300 and the conveying joint 650. The lower end of the positioning assembly 500 is provided with an image locator. After the image locator is accurately positioned, the deflection assembly 400 is controlled to deflect to a predetermined angle and dock with the transport vehicle 200.

[0029] The image locator can monitor the edge position of the filling port 210 for detection. The drive component 300 moves the image locator synchronously while driving the positioning component 500 to move. After the image locator detects the midpoint of the front edge line of the filling port 210, it sends a signal to the drive component 300 to control the drive component 300 to stop moving and complete the preliminary positioning; after the positioning component 500 completes the positioning, the deflection component 400 is controlled to deflect 180° toward the rear end of the filling port 210. When the size of the filling port 210 is constant, the deflection component 400 after deflection is opposite to the center position of the filling port 210. At this time, the conveying joint 650 and the conveying opening 651 at the lower end of the deflection component 400 are accurately docked with the filling port 210, and then the continuous filling of sulfuric acid is completed.

[0030] In summary, through the above-mentioned structural design, the image locator can be used to dock the midpoint position of the front end of the filling port 210, thereby realizing the preliminary positioning of the deflection assembly 400 and the positioning assembly 500, and then controlling the deflection assembly 400 to deflect by a predetermined angle, and controlling the deflection assembly 400 to move to the correct position for filling. By positioning the midpoint position of the front end of the filling port 210, the image locator can be used to quickly capture the image positioning point to achieve rapid positioning. At the same time, by controlling the deflection assembly 400 to deflect toward the rear end by a predetermined angle, the deflection assembly 400 and the filling port 210 can be controlled to be quickly and correctly positioned, thereby ensuring the rapid and stable filling of sulfuric acid, improving the efficiency of sulfuric acid filling, and greatly improving the safety of sulfuric acid filling.

[0031] Specifically, the deflection assembly 400 includes a deflection positioning rod 410, the lower end of the deflection positioning rod 410 is connected to the conveying opening 651, a main deflection member 560 is arranged between the upper end of the deflection positioning rod 410 and the positioning assembly 500, and a slave deflection member 520 is arranged between the lower end of the deflection positioning rod 410 and the positioning assembly 500. During the deflection control process, the main deflection member 560 serves as an active driving component, which can control the deflection positioning rod 410 to deflect a predetermined angle around the positioning assembly 500 from the upper end position, and the slave deflection member 520 at the lower end can play a supporting and limiting role to ensure the stability of the deflection positioning rod 410 during the deflection process.

[0032] A purification component 420 is provided on the side wall of the deflection positioning rod 410. The lower end of the purification component 420 is connected to the conveying opening 651, and the upper end of the purification component 420 is provided with an exhaust gas discharge opening. The purification component 420 can filter and purify the acid mist generated during the sulfuric acid filling process to prevent the acid mist from overflowing into the surrounding environment and affecting the surrounding filling environment.

[0033] The purification component 420 here also includes a purification shell 421, in which a horizontal purification layer plate 422 is fixed. The purification shell 421 is divided into two purification chambers 423 by the purification layer plate 422. The purification chamber 423 is filled with filter material, which can adsorb and filter the acid mist to reduce the components of the acid mist in the gas and ensure the normal discharge of the acid mist.

[0034] Specifically; the positioning assembly 500 includes a traction positioning rod 510, in which a first lifting assembly 540 is connected in series, a second lifting assembly 310 is provided between the drive assembly 300 and the upper end of the traction positioning rod 510, and the lower end of the second lifting assembly 310 is provided with an engaging fixing assembly connected to the upper end of the traction positioning rod 510.

[0035] The height position of the lower end of the traction positioning rod 510 can be adjusted by both the first lifting assembly 540 and the second lifting assembly 310. Before the sulfuric acid is filled, the height of the entire traction positioning rod 510 can be quickly adjusted by the second lifting assembly 310, and the traction positioning rod 510 can be controlled to be lifted to a predetermined height as a whole and staggered with the filling port 210. After the delivery connector 650 at the lower end of the traction positioning rod 510 is accurately docked with the filling port 210, the traction positioning rod 510 is controlled to be lowered as a whole by the second lifting assembly 310, and the delivery connector 650 is controlled to fit with the filling port 210, and then the filling of the sulfuric acid is completed.

[0036] During the sulfuric acid filling process, the bite fixing assembly is controlled to be in a separated state. At this time, the drive assembly 300 can be separated from the positioning assembly 500 and the deflection assembly 400 at the lower end. At this time, the drive assembly 300 can move to other positions to grab and position other deflection assemblies 400 and positioning assemblies 500, thereby realizing rapid filling of other transport vehicles 200.

[0037] After the sulfuric acid is filled in the deflection assembly 400 and the positioning assembly 500, the deflection assembly 400 and the positioning assembly 500 are in a relatively isolated state and cannot be adjusted in height by the second lifting assembly 310 in the drive assembly 300. At this time, the length of the retraction of the traction positioning rod 510 is adjusted by the first lifting assembly 540. The retraction of the traction positioning rod 510 can be controlled by the first lifting assembly 540, thereby raising the height of the bottom conveying joint 650 and separating it from the filling port 210. Subsequently, the transport vehicle 200 can drive out of the corresponding area to prepare for the entry of subsequent vehicles.

[0038] After the subsequent driving assembly 300 moves to the side of the deflection assembly 400 and the positioning assembly 500, the traction positioning rod 510 is again engaged and grasped by the bite fixing assembly, and the position of the deflection assembly 400 and the positioning assembly 500 is adjusted again according to the position of the subsequent incoming vehicle. While the second lifting assembly 310 controls the traction positioning rod 510 to lift, the first lifting assembly 540 controls the length of the traction positioning rod 510 to lengthen, preparing for the subsequent automatic filling of sulfuric acid.

[0039] In summary, through the above-mentioned structural design, a plurality of deflection assemblies 400 and positioning assemblies 500 can be docked through one drive assembly 300, thereby realizing the successive sulfuric acid filling at multiple workstations. Multiple drive controls can be completed simultaneously through one drive assembly 300, which reduces the idle rate of the drive assembly 300 while streamlining the structural design, avoiding structural deformation caused by excessive pressure on the positioning platform 100, resulting in subsequent bending deformation and even collapse of the entire structure. At the same time, it also reduces the structural layout, reduces the investment cost, and reduces the control difficulty.

[0040] Matchingly, an elastic component 430 is connected in series in the deflection positioning rod 410, and the elastic component 430 has a built-in guide component. The elastic component 430 here can be selected as an elastic pad or a reset spring, which can control the deflection positioning rod 410 to be a retractable structure. The deflection positioning rod 410 and the traction positioning rod 510 can be controlled to be retracted and extended synchronously to achieve precise and rapid driving, ensuring the coordinated control of the deflection component 400 and the positioning component 500, improving the control accuracy and efficiency while improving the control effect.

[0041] The positioning platform 100 includes a horizontal first positioning plate 110 and a second positioning plate 120, and also includes a vertically arranged column 130. The first positioning plate 110 and the second positioning plate 120 are fixed inside the column 130, the second positioning plate 120 and the first positioning plate 110 are arranged at intervals, and the second positioning plate 120 is located at a higher position; a guide channel is opened on the surface of the second positioning plate 120 to pass through from top to bottom, and a positioning ring 550 located at the upper end of the second positioning plate 120 is fixed to the side wall of the traction positioning rod 510, and a buffer pad is fixed to the lower end of the positioning ring 550. Through the above structural design, after the driving assembly 300 is disengaged from the corresponding traction positioning rod 510, the traction positioning rod 510 can contact the guide channel under the action of gravity. Specifically, the positioning ring 550 at the upper end of the traction positioning rod 510 can support and limit the traction positioning rod 510, ensuring that the positioning assembly 500 is in a relatively stable state in the positioning platform 100, thereby ensuring the stability of sulfuric acid filling.

[0042] Specifically, the guide channel includes a transversely arranged main channel 121 and a plurality of longitudinally arranged branch channels 122. The sizes of the main channel 121 and the branch channels 122 are smaller than the position of the horizontal cross-section at the bottom of the positioning ring 550. The driving assembly 300 can drive the traction positioning rod 510 in the bite state to move linearly along the main channel 121 and the branch channel 122, and move to a predetermined position according to the filling requirements to ensure the stability of the filling. At the same time, due to the large size of the positioning ring 550, the positioning ring 550 and the traction positioning rod 510 will not fall to the lower position, thereby ensuring the normal and stable filling of sulfuric acid.

[0043] Here, multiple branch channels 122 are arranged on both sides of the main channel 121 to increase the range of movement of the traction positioning rod 510. At the same time, the size of the traction positioning rod 510 is much smaller than the size of the branch channel 122 and the main channel 121, and the traction positioning rod 510 can be adjusted precisely within a small range to meet the filling needs of trucks in different positions.

[0044] At the same time, through the above structural design, the image locator can also locate the center points of different side lengths of the filling port 210, and then control the deflection assembly 400 to deflect in the corresponding direction by a predetermined angle, and control the lower conveying joint 650 to be relative to the center of the filling port 210.

[0045] A plurality of horizontally arranged limit frames 111 are fixed on the inner wall of the first positioning plate 110, and the filling device 600 is located in the limit frame 111. The limit frame 111 can limit the moving position of the filling device 600 to prevent the filling device 600 from moving beyond the predetermined position and affecting the filling of adjacent filling devices 600, thereby ensuring the normal filling of multiple filling devices 600.

[0046] Specifically; the drive assembly 300 includes a transverse drive and a longitudinal drive that cross each other. The above drives can be selected as electric rails or telescopic rods to achieve drive control at two positions, driving the conveying joint 650 below to move to various positions within the horizontal position, thereby realizing rapid filling positioning of the transport vehicle 200 at different positions.

[0047] The present invention is further described below in conjunction with a filling method.

[0048] A method for automatically filling and loading sulfuric acid, using the above-mentioned automatic sulfuric acid filling and loading equipment, comprises the following steps: S1. After the transport vehicle 200 moves to the predetermined position, the image locator is used to perform image positioning on the filling port 210 at the upper end of the transport vehicle 200. During the image positioning process, the driving component 300 moves to complete the image positioning. The filling port 210 is rectangular. During the movement of the driving component 300, the image locator is driven to detect the edge position of the filling port 210, detect the center position of the positioning edge line, and complete the preliminary positioning.

[0049] S2. After the image positioning in step S1 is completed, the deflection assembly 400 is controlled to deflect to a predetermined angle to dock with the transport vehicle. After docking with the transport vehicle is completed, sulfuric acid is filled into the transport vehicle 200 through the filling device 600. After deflecting to a predetermined angle, the deflection assembly 400 drives the conveying joint 650 to deflect to the upper end position of the filling port 210 and opposite to the filling port 210. Then, the conveying joint 650 is controlled to descend and fit with the surface of the filling port 210 to complete the filling of sulfuric acid.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
