DETAILED DESCRIPTION

[0036] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0037] The following description sets forth many specific details to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the implementation methods in the specification are only part of the implementation methods of the present invention, rather than all of the implementation methods.

[0038] Combination Figures 1 to 4As shown, the liquid loading equipment provided by the embodiment of the present invention includes a support frame 1, a positioning device 2 and a liquid loading device 3. The positioning device 2 is movably arranged on the support frame 1, and the liquid loading device 3 is connected to the positioning device 2. The positioning device 2 is configured to drive the liquid loading device 3 to move above the tank mouth 4. The liquid loading device 3 includes a liquid guiding member 31, a telescopic member 32 and a sealing member 33, wherein the sealing member 33 has a pressing surface that matches the shape of the tank mouth 4, and the matching here means that the bottom structure of the sealing member 33 and the structure at the position around the tank mouth 4 can cooperate with each other, so that the sealing member 33 can be pressed and sealed at the tank mouth 4 of the tank truck to ensure the sealing effect. The sealing member 33 is arranged at the bottom of the telescopic member 32, and the telescopic member 32 can drive the sealing member 33 to move in the vertical direction, and then when the positioning device 2 drives the liquid loading device 3 to move above the tank mouth 4, the telescopic member 32 can drive the sealing member 33 to move downward, so that the sealing member 33 is sealed at the tank mouth 4 position of the tank body, so as to realize automatic control.

[0039] The liquid-guiding member 31 includes an external sealing tube 311, a ventilation outer tube 312, a telescopic sleeve 313 and a liquid inlet pipe 314, which are arranged in sequence from the outside to the inside. The bottom end of the external sealing tube 311 is connected to the sealing member 33. The connection method here is not limited. For example, the bottom end of the external sealing tube 311 and the sealing member 33 can be directly connected, or indirectly connected through other components. It is only necessary to ensure that the external sealing tube 311 can follow the movement of the sealing member 33 during the movement of the sealing member 33. The top end of the external sealing tube 311 is sealed and slidably matched with the ventilation outer tube 312, so that the external sealing tube 311 can move along the extension direction of the ventilation outer tube 312, and the external sealing tube 311 is always sealed with the ventilation outer tube 312 during the movement to prevent gas leakage during the movement of the sealing member 33. An exhaust channel connected to the exhaust pipe 7 is formed between the ventilation outer tube 312 and the telescopic sleeve 313. An exhaust port connected to the exhaust channel is provided on the sealing component 33, so that the gas in the tank body can enter the exhaust pipe 7 through the exhaust channel, and then be collected by the gas collecting device connected to the exhaust pipe 7, and then be centrally processed to avoid polluting the environment. The top of the liquid inlet pipe 314 is connected to the positioning device 2, so that the liquid inlet pipe 314 serves as a supporting structure of the liquid guiding component 31. The liquid is introduced through the liquid inlet pipe 314. During the introduction of the liquid, the telescopic sleeve 313 can be expanded to extend the liquid outlet to the target position of the tank body, thereby increasing the guiding distance of the liquid, reducing the splashing range and height of the liquid, and ensuring the liquid transportation effect.

[0040] The liquid loading equipment provided by the present invention can automatically adjust the position of the liquid loading device 3 through the positioning device 2, so that the liquid loading device 3 can automatically move to the top of the tank mouth 4, and drive the sealing member 33 to move downward through the telescopic member 32, so that the sealing member 33 is pressed against the position of the tank mouth 4 to achieve the sealing of the tank mouth 4, and then the liquid is provided toward the tank body through the liquid guiding member 31, so that the liquid is transported in a sealed environment, the positioning and transportation process is automated, the staff participation is reduced, the labor cost is reduced, and the safety problems caused by manual operation errors are avoided. In addition, during the movement of the sealing member 33 driven by the telescopic member 32, the external sealing tube 311 and the ventilation outer tube 312 are always sealed, so that the gas can be discharged through the exhaust channel formed between the ventilation outer tube 312 and the telescopic sleeve 313, avoiding the phenomenon of gas leakage, thereby avoiding environmental pollution, and eliminating the problem of safety accidents caused by gas leakage.

[0041] Combination Figure 2 and Figure 4 As shown, the sealing member 33 includes a sealing disc 331 and an angle adjustment member 332 arranged on the top of the sealing disc 331, the angle adjustment member 332 is connected to the bottom of the telescopic member 32 and the bottom of the external sealing tube 311, and a pressing surface is formed at the bottom of the sealing disc 331, wherein the sealing disc 331 can change the angle between the plane where the sealing disc 331 is located and the horizontal plane under the action of the angle adjustment member 332. Under this design mode, the telescopic member 32 can drive the angle adjustment member 332 to move along the vertical direction, and then drive the sealing disc 331 and the external sealing tube 311 to move along the vertical direction through the angle adjustment member 332, and the angle adjustment member 332 can change the angle between the plane where the sealing disc 331 is located and the horizontal plane, so that when the tank mouth 4 is tilted, the sealing disc 331 can still be sealed with the tank mouth 4, ensuring the sealing effect of the tank mouth 4 under various working conditions.

[0042] As a feasible implementation method, Figure 4As shown, the angle adjustment member 332 includes a ball bearing 3321 sleeved on the outer periphery of the telescopic sleeve 313 and a bearing seat 3322 matched with the ball bearing 3321, the bearing seat 3322 is connected to the sealing disk 331, and the bottom of the telescopic member 32 and the bottom of the external sealing tube 311 are both connected to the ball bearing 3321. Specifically, the top of the ball bearing 3321 extends out of the mounting seat, and the bottom of the telescopic member 32 and the bottom of the external sealing tube 311 are both connected to the mounting seat of the ball bearing 3321. Further optimized, the outer periphery of the mounting seat is provided with a driving plate, and the bottom of the telescopic member 32 is connected to the driving plate. Under this design mode, the ball bearing 3321 can move in the vertical direction under the action of the telescopic member 32, and the bearing seat 3322 can drive the sealing disk 331 to rotate around the ball bearing 3321 in any direction to change the angle between the plane where the sealing disk 331 is located and the horizontal plane direction, so as to ensure that the sealing plate can be sealed with the tank mouth 4.

[0043] Specifically, continue to refer to Figure 4 The bearing seat 3322 includes an upper seat body 33221 and a lower seat body 33222, and the inner sides of the upper seat body 33221 and the lower seat body 33222 are both in an arc shape matching the ball bearing 3321, so that the upper seat body 33221 and the lower seat body 33222 can rotate relative to the ball bearing 3321. The upper seat body 33221 and the lower seat body 33222 are connected by bolts to ensure the convenience of disassembly and assembly of the upper seat body 33221 and the lower seat body 33222 and the firmness of the connection. In addition, the bolts pass through the upper seat body 33221 and the lower seat body 33222 from top to bottom in sequence, and are screwed on the sealing disk 331 to achieve the connection between the sealing disk 331 and the bearing seat 3322.

[0044] Further optimized, in order to ensure the alignment effect between the upper seat body 33221 and the lower seat body 33222, a snap ring can be set at the bottom of the inner wall of the upper seat body 33221, and a ring groove can be set at the top of the inner wall of the lower seat body 33222. When the snap ring is inserted into the ring groove, the upper seat body 33221 and the lower seat body 33222 are accurately aligned, which increases the convenience of operation. And in order to ensure the sealing effect between the ball bearing 3321 and the bearing seat 3322, a first sealing ring can be set in the ring groove. The first sealing ring extends out of the lower seat body 33222, and the inner wall of the first sealing ring is pressed against the outer periphery of the ball bearing 3321 to ensure that during the rotation of the sealing disk 331, gas and liquid will not flow out from the gap between the bearing seat 3322 and the ball bearing 3321 to avoid polluting the environment.

[0045] The sealing disk 331 includes a tank mouth 4 sealing flange 3311 sleeved on the outer periphery of the telescopic sleeve 313 and a tank mouth 4 sealing rubber 3312 arranged at the bottom of the tank mouth 4 sealing flange 3311, and the tank mouth 4 sealing flange 3311 is connected to the bearing seat 3322. Specifically, the tank mouth 4 sealing flange 3311 and the tank mouth 4 sealing rubber 3312 are connected by a bolt group, and the bolt group includes a plurality of bolts, and the plurality of bolts are arranged at intervals along the circumferential direction of the tank mouth 4 sealing flange 3311 to ensure the firmness and tightness of the connection. In addition, the bolt group can also be a plurality of groups, and the plurality of groups of bolt groups are arranged at intervals along the radial direction of the tank mouth 4 sealing flange 3311 to further ensure the firmness of the connection. Among them, the tank mouth 4 sealing flange 3311 can provide support for the tank mouth 4 sealing rubber 3312 to ensure that the tank mouth 4 sealing rubber 3312 can press the tank mouth 4 to seal the tank mouth 4. Among them, the tank mouth 4 sealing flange 3311 is connected to the above-mentioned bearing seat 3322 by bolts.

[0046] Further optimization, such as Figure 4 As shown, a guide block 3313 is provided on the inner wall of the sealing flange 3311 of the tank mouth 4, and the inner wall of the guide block 3313 has a sloped surface inclined downward. Specifically, the sealing flange 3311 of the tank mouth 4 and the guide block 3313 are connected by bolts to increase the convenience of disassembly and assembly and the firmness of the connection. In addition, the downward inclination here means that the guide block 3313 has a sloped surface, and the sloped surface is inclined downward, that is, the inner diameter of the guide block 3313 gradually decreases from top to bottom. By providing the guide block 3313, it can play a guiding role for the sealing rubber 3312 of the tank mouth 4 to seal the tank mouth 4, so that the sealing rubber 3312 of the tank mouth 4 can be pressed against the outer periphery of the tank mouth 4. Specifically, when the sealing rubber 3312 of the tank mouth 4 moves toward the tank mouth 4 under the action of the telescopic member 32, the outer periphery of the edge of the tank mouth 4 should preferentially contact the slope surface of the guide block 3313, and the guide block 3313 can guide the sealing rubber 3312 of the tank mouth 4 to align with the tank mouth 4, and continue to lower the sealing rubber 3312 of the tank mouth 4 until the sealing rubber 3312 of the tank mouth 4 is pressed against the outer periphery of the end of the tank mouth 4. This design method can allow slight errors in the positioning of the liquid loading device 3, and the error can be eliminated by the guide block 3313, thereby ensuring the accuracy of the pressing position of the sealing rubber 3312 of the tank mouth 4 and ensuring the sealing effect of the tank mouth 4.

[0047] Further optimization, such as Figure 1 As shown, a tuning fork assembly 333 is provided at the bottom of the tank mouth 4 sealing rubber 3312. Specifically, the tuning fork assembly 333 may include an upper tuning fork probe 3331 and a lower tuning fork probe 3332, and both the upper tuning fork probe 3331 and the lower tuning fork probe 3332 pass through the tank mouth 4 sealing rubber 3312 and the tank mouth 4 sealing flange 3311 through a signal line and are fixedly mounted on the tank mouth 4 sealing flange 3311.

[0048] This design can measure the liquid level in the tank through the upper tuning fork probe 3331 and the lower tuning fork probe 3332, thereby avoiding the phenomenon of liquid leakage caused by a large amount of liquid filled. Among them, the tuning fork probe is a permanent component for detecting the liquid level, and its structure and working principle are not described in detail here.

[0049] The support frame 1 of the present application can be arranged in a variety of ways. For example, the support frame 1 can be arranged on the side of the track, and part of the support frame 1 extends above the track, and the extended position of the support frame 1 should not affect the normal walking of the train on the track. For another example, the support frame 1 can be a gantry, and the opening of the gantry should allow the train to pass through. The following specific examples are given:

[0050] In some embodiments, the support frame 1 is disposed on one side of the track, and the support frame 1 includes an extension portion, which extends above the track and extends in a direction perpendicular to the track. The support height of the extension portion should be higher than the height of the train. The positioning device 2 is movably disposed on the extension portion, and the positioning mode of the positioning device 2 may include the following two forms:

[0051] In form one, the position of the adjusting device 2 in the extension direction of the track does not change, and only the position of the liquid loading device 3 in the extension direction perpendicular to the track is changed by the adjusting device 2. At this time, the stopping position of the train is fixed, that is, after the train stops, the center line of the tank body is below the extension part, so that the adjusting device 2 only needs to adjust the position in one direction to adjust the liquid loading device 3 to the top of the tank mouth 4, thereby increasing the convenience of adjustment.

[0052] In form two, the position of the adjusting device 2 in the extension direction of the track and the direction perpendicular to the extension direction of the track changes, that is, the position of the liquid loading device 3 in the extension direction of the track and the direction perpendicular to the extension direction of the track can be adjusted by the adjusting device 2. At this time, the stopping position of the train may have a small range of deviation, that is, after the train stops, the center line of the tank body is near the bottom of the extension part, and the liquid loading device 3 can be adjusted to the top of the tank mouth 4 by adjusting the position of the adjusting device 2 in two directions, which is convenient for adjustment and reduces restrictions on the train stop position.

[0053] In other embodiments, the support frame 1 includes columns 11 arranged on both sides of the track and a truss 12 connected to the top of the two columns 11, and the positioning device 2 is movably arranged on the truss 12. In this design, the two columns 11 are respectively located on the outside of the track, and the truss 12 is connected to the top of the two columns 11, so that a gantry structure is formed between the truss 12 and the two columns 11, wherein the supported height of the truss 12 should be greater than the height of the train to avoid affecting the running of the train on the track. The structural stability of the support frame 1 of this design is good. Similarly, the positioning method of the positioning device 2 may include the following two forms:

[0054] In form one, the position of the adjusting device 2 in the extension direction of the track does not change, and only the position of the liquid loading device 3 in the extension direction perpendicular to the track is changed by the adjusting device 2. At this time, the stopping position of the train is fixed, that is, after the train stops, the center line of the tank body is below the extension part, so that the adjusting device 2 only needs to adjust the position in one direction to adjust the liquid loading device 3 to the top of the tank mouth 4, thereby increasing the convenience of adjustment.

[0055] In form two, the position of the adjusting device 2 in the extension direction of the track and the direction perpendicular to the extension direction of the track changes, that is, the position of the liquid loading device 3 in the extension direction of the track and the direction perpendicular to the extension direction of the track can be adjusted by the adjusting device 2. At this time, the stopping position of the train may have a small range of deviation, that is, after the train stops, the center line of the tank body is near the bottom of the extension part, and the liquid loading device 3 can be adjusted to the top of the tank mouth 4 by adjusting the position of the adjusting device 2 in two directions, which is convenient for adjustment and reduces restrictions on the train stop position.

[0056] An oil receiving pan 111 is provided on the side of one of the columns 11, and the oil receiving pan 111 is fixedly mounted on the column 11. When the liquid delivery is completed, the liquid loading device 3 is reset, and the liquid loading device 3 moves to the top of the oil receiving pan 111 to receive the liquid dripped from the liquid loading device 3 through the oil receiving pan 111. Further optimized, the oil receiving pan 111 is at an angle of 2° with the horizontal direction to facilitate the collection of liquid.

[0057] The positioning device 2 of the present application includes a vehicle body 21 and a walking assembly 22 disposed on the vehicle body 21. The top end of the liquid inlet pipe 314 is connected to the vehicle body 21. The walking assembly 22 can drive the vehicle body 21 to move along the length direction of the truss 12, thereby driving the liquid inlet pipe 314 to move along the length direction of the truss 12. A position detection assembly 23 is disposed on the vehicle body 21, and the position detection assembly 23 is signal-connected to the walking assembly 22. The position detection assembly 23 can detect the position of the walking assembly 22 in real time, and feed back the position information to the walking assembly 22 until the walking assembly 22 drives the liquid inlet pipe 314 to move to the target position, and then the walking assembly 22 stops moving.

[0058] As a feasible implementation, the position of the positioning device 2 in the extension direction of the track does not change, and only the position of the liquid loading device 3 in the extension direction perpendicular to the track is changed by the positioning device 2. The position detection component 23 includes a laser positioner 231 arranged on the vehicle body 21, and a fixing plate 232 is provided at the end of the vehicle body 21. The laser positioner 231 is arranged on the fixing plate 232, wherein the laser positioner 231 can be arranged above the fixing plate 232. At this time, the measuring end of the laser positioner 231 can extend out of the fixing plate 232 to detect the position of the tank mouth 4 below the fixing plate 232. Alternatively, the laser positioner 231 can be directly arranged at the bottom of the fixing plate 232, which is not restrictive.

[0059] During use, when the train moves into position, the positioning device 2 drives the liquid loading device 3 to move along the extension direction perpendicular to the track until the laser aligner 231 detects the position of the edge of the tank mouth 4, and records the position information of the edge. The positioning device 2 continues to move until the laser aligner 231 detects the position of the other side of the tank mouth 4, and records the position information of the other side. At this time, the diameter of the tank mouth 4 can be obtained through the two position information, and then the position of the center line of the tank mouth 4 can be obtained, as well as the distance between the center line of the liquid loading device 3 and the center line of the tank mouth 4 at this time (the distance between the center line of the liquid loading device 3 and the laser aligner 231 is fixed). After the positioning device 2 moves the distance between the center line of the liquid loading device 3 and the center line of the tank mouth 4 in the reverse direction, the liquid loading device 3 can be moved to the top of the tank mouth 4, which is convenient for adjustment and accurate in positioning. Since the tank mouth 4 will protrude upward from the tank body, the laser aligner 231 can detect the edge information of the tank mouth 4 by measuring the height difference of the signal sent and returned by the laser aligner 231.

[0060] For example, the laser aligner 231 emits a laser vertically downward. In the initial state, the laser irradiates the tank body. At this time, the distance between the measuring point on the tank body irradiated by the laser and the laser aligner 231 is L1. When the laser aligner 231 follows the movement of the positioning device 2, the value of L1 gradually changes (when the top of the tank body is flat, the value of L1 remains basically unchanged), until the laser aligner 231 moves to the edge of the tank mouth 4, the distance between the measuring point on the tank body irradiated by the laser and the laser aligner 231 changes. At this time, the distance between the measuring point on the tank body irradiated by the laser and the laser aligner 231 is L2 (when the top of the tank body is a curved surface, L2 can be a set value, and when the top surface of the tank body is a flat surface, L 2 does not need to be set), L2<L1, record the position information of the edge of the tank mouth 4 when the distance changes, the laser aligner 231 continues to move after following the positioning device 2, and after the laser aligner 231 is aligned with the position of the tank mouth 4, the laser is irradiated into the tank mouth 4, and the distance between the measuring point where the laser is irradiated inside the tank mouth 4 and the laser aligner 231 is L3, wherein L3 is much larger than L1 and L2, and the laser aligner 231 continues to move until the laser aligner 231 moves to the position of the other edge of the tank mouth 4, at this time, the distance between the measuring point where the laser is irradiated on the tank body and the laser aligner 231 is L2 (can be close to L2 when the tank mouth 4 is tilted), and record the position information of the edge of the tank mouth 4 when the distance changes. After the above-mentioned positioning and feedback, the distance between the two sides can be obtained through the position information of the corresponding two sides of the tank mouth 4, and then the position information of the center line of the tank mouth 4 can be obtained, and then the liquid loading device 3 can be moved to the top of the tank mouth 4 by the reverse movement of the positioning device 2, wherein the center line of the liquid loading device 3 and the center line of the tank mouth 4 may not completely coincide, and a certain error is allowed, which can be eliminated by the above-mentioned guide block 3313.

A mounting plate 211 is provided on the vehicle body 21, and the top of the liquid inlet pipe 314 is connected to the mounting plate 211 by a flange to ensure the firmness of the connection. A crossbeam is also provided on the vehicle body 21, and the first drive motor 2231 is arranged on the crossbeam, and the output shaft of the first drive motor 2231 extends along the length direction of the vehicle body 21.

The coupling 2233 and the first reducer 2232 are installed on the vehicle body 21. The first reducer 2232 is connected to the middle of the active shaft 2211, so that the first reducer 2232 can evenly transmit the rotation of the first drive motor 2231 to the active shaft 2211 to ensure the stability of the vehicle body 21 during walking.

[0063] Combination Figure 2 , Figure 3 and Figure 4As shown, the telescopic sleeve 313 includes a first tube body 3131, a second tube body 3132 and a third tube body 3133 which are sequentially sleeved from the inside to the outside. The first tube body 3131, the second tube body 3132 and the third tube body 3133 can be deployed under the action of their own weight, and can be retracted under the action of external force. In this design, the first tube body 3131, the second tube body 3132 and the third tube body 3133 can be deployed when conveying liquid, so as to guide the liquid to ensure that the liquid can be conveyed to the target position. In addition, when not in use, the first tube body 3131, the second tube body 3132 and the third tube body 3133 can be retracted to avoid affecting the normal use of the device.

[0064] As a feasible implementation manner, a first upper limit block 31311, a second upper limit block 31321 and a third upper limit block 31331 are respectively provided on the inner walls of the top ends of the first tube body 3131, the second tube body 3132 and the third tube body 3133, and a first lower limit block 3143, a second lower limit block 31312 and a third lower limit block 31322 are respectively provided on the outer walls of the bottom ends of the liquid inlet pipe 314, the first tube body 3131 and the second tube body 3132, wherein the first upper limit block 31311 and the first lower limit block 3143, the second upper limit block 31321 and the second lower limit block 31312, and the third upper limit block 31331 and the third lower limit block 31322 are respectively snap-fitted together. When in use, the first tube body 3131, the second tube body 3132 and the third tube body 3133 will move downward under the action of their own gravity when there is no external traction, until the first upper limit block 31311 and the first lower limit block 3143, the first upper limit block 31311 and the first lower limit block 3143 are respectively engaged, and the telescopic sleeve 313 is fully unfolded. At this time, the telescopic sleeve 313 is unfolded with the third tube body 3133 at the bottom and the first tube body 3131 at the top, so that the liquid passes through the liquid inlet pipe 314, the first tube body 3131, the second tube body 3132 and the third tube body 3133 in sequence and then enters the tank body.

[0065] The liquid loading equipment of the present application also includes a flow guide component 34 and a lifting component 35. The flow guide component 34 is arranged at the bottom end of the third tube body 3133, and the lifting component 35 is arranged on the positioning device 2. The lifting component 35 is arranged to be able to lift or lower the flow guide component 34 to expand or retract the telescopic sleeve 313. Under this design mode, the flow guide component 34 can play a guiding role in the transportation of liquid, ensuring that the transportation of liquid meets the design requirements, and can drive the expansion or recovery of the telescopic sleeve 313 by the bottom or retraction of the flow guide component 34, with a compact structure and convenient operation.

[0066] As a feasible implementation, the lifting assembly 35 includes a winch disposed on the positioning device 2 and a pull rope 351 that can be reeled or released by the winch, and the pull rope 351 passes through the liquid inlet pipe 314 and is connected to the flow guide assembly 34. The winch can be disposed on the vehicle body 21, specifically, on the above-mentioned mounting plate 211 of the vehicle body 21, and the pull rope 351 passes through the mounting plate 211 and extends into the liquid inlet pipe 314. In this design, the pull rope 351 can pass through the liquid inlet pipe 314 to connect to the flow guide assembly 34, and the stretching work will not be affected by the delivery of the liquid, thereby ensuring the position adjustment effect of the flow guide assembly 34.

[0067] Specifically, the winch includes a second drive motor 352 and a second reducer 353 arranged on the output shaft of the second drive motor 352, the output end of the second reducer 353 is connected to a winch wheel, stretched and wound on the winch wheel, and the second drive motor 352 and the second reducer 353 are both arranged on the mounting plate 211 of the vehicle body 21. The winch of this design can control its own rotation speed and is easy to adjust.

[0068] Combination Figure 2 and Figure 4 As shown, the guide assembly 34 includes a seat body 341 connected to the third tube body 3133 and a guide plate 342 disposed on the seat body 341. The top of the guide plate 342 has a guide surface, wherein the guide surface is arc-shaped so as to buffer the liquid and reduce the liquid splashing range. A diversion port is provided at a position corresponding to the guide surface of the seat body 341. The liquid flows out through the diversion port after being guided by the guide plate 342, and then flows to a specified direction to meet the liquid transportation requirements. An adjustment ring is connected to the top of the guide plate 342, and the end of the pull rope 351 is connected to the adjustment ring, which increases the convenience of connecting the guide plate 342 with the pull rope 351.

[0069] Specifically, the seat body 341 includes a flange plate, and a first connecting plate is provided at the outer periphery of the bottom end of the third tube body 3133, wherein the first connecting plate is welded to the third tube body 3133 to ensure the fixing effect, and the flange plate covers the first tube body 3131 and the second tube body 3132 in the vertical direction, so that the flange plate can drive the first tube body 3131, the second tube body 3132 and the third tube body 3133 to move upward during the lifting process to achieve the retraction of the telescopic sleeve 313. The flange plate and the first connecting plate are connected by bolts to increase the convenience of disassembly and assembly, and there are multiple bolts, and the multiple bolts are arranged at intervals along the circumferential direction of the flange plate to ensure the connection strength between the flange plate and the first connecting plate. The seat body 341 also includes a panel arranged below the flange plate, the top end of the panel is welded to the bottom end of the flange plate, and the bottom end of the panel is welded to the edge of the guide plate 342 to ensure the structural strength of the guide assembly 34. The diversion port is opened on the enclosure, and the position and size of the diversion port can be designed according to actual needs to meet the liquid transportation needs.

[0070] In normal state (non-use state), the winch rotates, the pull rope 351 contracts, and the pull rope 351 drives the guide plate 342 to move upward. At this time, the guide plate 342 pushes the first tube body 3131, the second tube body 3132 and the third tube body 3133 to move upward through the enclosure and the flange plate until the first tube body 3131, the second tube body 3132 and the third tube body 3133 are retracted and the positions of the first tube body 3131, the second tube body 3132 and the third tube body 3133 are maintained by the flange plate.

[0071] When in use, the winch rotates and the pull rope 351 is lowered. At this time, the force restricting the first tube body 3131, the second tube body 3132 and the third tube body 3133 is eliminated, and the first tube body 3131, the second tube body 3132 and the third tube body 3133 move downward under the action of their own gravity until the first tube body 3131, the second tube body 3132 and the third tube body 3133 are unfolded, so that liquid can be transported.

[0072] The unfolded length of the telescopic catheter, specifically the lower length of the third tube body 3133 , can be adjusted by controlling the lowering length of the pull rope 351 , so that the liquid can flow out from a specified height.

[0073] Combination Figure 2 and Figure 3 As shown, a support plate 3141 is provided on the periphery of the liquid inlet pipe 314, and the top of the telescopic member 32 and the top of the ventilation outer tube 312 are both connected to the support plate 3141.

Further optimized, there are multiple bolts, and the multiple bolts are arranged at intervals along the circumferential direction of the second connecting plate to increase the firmness of the connection between the second connecting plate and the support plate 3141. A connecting plate is provided on the top of the telescopic member 32, and the connecting plate is bolted to the support plate 3141 and the second connecting plate to ensure the connection strength. Among them, the telescopic member 32 can be a structure that can be driven along a straight line, such as a cylinder or a hydraulic cylinder. This design is relatively common in the prior art. Therefore, this application does not describe the specific structure of the telescopic member 32 in detail.

[0075] The liquid inlet pipe 314 of the present application can adopt a split design, that is, the liquid inlet pipe 314 can be divided into an upper pipe and a lower pipe, and the upper pipe and the lower pipe are threadedly connected to increase the convenience of disassembly and assembly, and the support plate 3141 can be arranged on the outer periphery of the lower pipe or the outer periphery of the upper pipe, which are not restrictive. The liquid inlet pipe 314 of this design is convenient for production and transportation, and avoids the phenomenon of production and transportation restrictions caused by the pipe being too long.

[0076] In addition, the top end of the external sealing tube 311 is sealed and slidably matched with the ventilation outer tube 312 in the following manner:

[0077] As a feasible implementation method, Figure 5 As shown, an adjustment sleeve 3111 is provided at the outer periphery of the top end of the external sealing tube 311, and a compression sleeve 3112 is bolted to the top end of the adjustment sleeve 3111. A sealing gasket 3113 is provided at the top end of the external sealing tube 311, and the outer ring of the sealing gasket 3113 is connected to the adjustment sleeve 3111, and the inner ring of the sealing gasket 3113 is pressed against the outer wall of the ventilation outer tube 312. The top end of the adjustment sleeve 3111 extends out of the top end of the external sealing tube 311, and an annular groove is provided on the inner wall of the extended end of the adjustment sleeve 3111, and the annular groove is filled with a sealing filler 3114, and the sealing filler 3114 can slide with the outer wall of the ventilation outer tube 312, and the compression sleeve 3112 can press the sealing filler 3114 in the annular groove under the action of the bolt force to ensure the sealing effect between the external sealing tube 311 and the ventilation outer tube 312. Among them, the sealing filler 3114 is a conventional component used for sliding sealing, and no more description is made here.

[0078] Combination Figure 2 and Figure 3 As shown, a sleeve 3142 is provided on the top of the support plate 3141, and the sleeve 3142 is sleeved on the outer periphery of the liquid inlet pipe 314, and the top of the sleeve 3142 is sealed and connected to the liquid inlet pipe 314, so that an exhaust gap connected to the exhaust channel is formed between the sleeve 3142 and the liquid inlet pipe 314, and the exhaust pipe 7 is connected to the exhaust gap. In this design, the gas in the pipe body will be discharged through the exhaust channel and the exhaust gap in sequence to meet the exhaust demand, and the exhaust pipe 7 in this design will not affect the normal use of the body loading device.

[0079] Continue to refer to Figure 2 and Figure 3 The liquid loading device further includes a liquid infusion pipeline 5, which passes through the sleeve 3142 and extends into the liquid inlet pipeline 314. Specifically, one end of the liquid infusion pipeline 5 is connected to the liquid infusion device, and the other end of the liquid infusion pipeline 5 passes through the sleeve 3142 and the liquid inlet pipeline 314 and extends into the liquid inlet pipeline 314, so that the liquid infusion device can transport the liquid into the liquid inlet pipeline 314.

[0080] Since the staff need to go to the tanker port to open the tank port 4 sealing cover and other operations, Figure 7 As shown, the liquid loading equipment also includes an anti-fall device 6 to protect the safety of the staff through the anti-fall device 6. The anti-fall device 6 includes an anti-fall bracket 61 and an anti-fall trolley 62 walking on the anti-fall bracket 61. The anti-fall bracket 61 is fixedly installed on the top steel structure beam of the loading crane position. The anti-fall trolley 62 is connected to a fall-stopping component 63, and the fall-stopping component 63 is connected to an anti-fall rope 64. When the operator carries out high-altitude operations, the fall-stopping hook of the anti-fall rope 64 is hung on the safety belt worn by the operator. Once a person falls, the fall-stopping component 63 will protect the personal safety of the operator. Among them, the fall-stopping component 63 is a conventional design in the field, and its structure and working principle are not described in detail here. When not in use, the anti-fall rope 64 can be movably connected to the fence 65 through the fall-stopping hook to facilitate the collection and release of the anti-fall rope 64.
