Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention / utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention / utility model, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0028] In the description of this invention / utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention / utility model, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention / utility model.

[0029] See Figure 1 and Figure 2On one hand, this invention provides a tank truck safety loading device, including a loading platform 1, a discharge channel 2, and a steering component. The loading platform 1 is suspended and has a lower pipe opening 8. The discharge channel 2 passes through the lower pipe opening 8. The steering component includes a seat and a ball 14. The seat is located on the loading platform 1 and includes two opposing first and second surfaces. The first and second surfaces are respectively provided with spherical recesses. The ball 14 is located between the first and second surfaces and is partially accommodated in the spherical recesses. The ball 14 is provided with an installation channel 17, and the center of the ball 14 is located at the axis of the installation channel 17. The discharge channel 2 passes through the installation channel 17. The ball 14 is provided with a medium cavity 15, which surrounds the installation channel 17. The top volume of the medium cavity 15 is smaller than the bottom volume of the medium cavity 15. A movable plate is provided inside the medium cavity 15. The movable plate slides and seals with the inner wall of the medium cavity 15. The movable plate is used to divide the medium cavity 15 into upper and lower chambers.

[0030] Loading platform 1 is a component used to allow operators to stand at a high position. Loading platform 1 can be raised and lowered by lifting equipment or fixed to a building.

[0031] The loading platform 1 can be equipped with railings, which improves the safety of operators on the loading platform 1.

[0032] Operators stand on loading platform 1 to carry out loading operations. On the one hand, operators do not have to climb up and down the tank, reducing their workload. On the other hand, operators can stand stably on loading platform 1, improving loading safety.

[0033] The lower pipe port 8 is used to supply material discharge channel 2 from top to bottom.

[0034] The spherical recesses on the first and second surfaces form a receiving space, and the sphere 14 is partially received in the recess of the sphere 14, so that the sphere 14 can rotate relative to the base.

[0035] The installation channel 17 is used for the discharge channel 2 to pass through, so that when the ball 14 rotates, it can drive the discharge channel 2 to move together. The ball 14 can be set below the discharge port, so that the discharge channel 2 can enter the installation channel 17 after passing through the lower pipe port 8.

[0036] When the tank truck 6 is parked under the loading platform, there may be a deviation between the inlet of the tank and the outlet 8. The orientation of the installation channel 17 can be adjusted by rotating the ball 14, which in turn makes it easier to adjust the orientation of the discharge channel 2 so that the discharge channel 2 can discharge material into the tank.

[0037] The top volume of the dielectric cavity 15 is smaller than the bottom volume of the dielectric cavity 15, so that the center of gravity of the dielectric cavity 15 is located at the bottom of the dielectric cavity 15.

[0038] The media cavity 15 of the mounting channel 17 is used to adjust the center of gravity of the sphere 14. This facilitates the reset of the sphere 14 after use for future use, and also improves the stability of the discharge channel 2 when the mounting channel 17 is in a vertical position. Specifically, the media cavity 15 can be filled with media. Due to the top-heavy, bottom-light structure of the media cavity 15, the bottom of the media cavity 15 is heavier and the top is lighter, so that the center of gravity of the sphere 14 can be located below the center of the sphere 14.

[0039] The movable plate slides and seals with the inner wall of the medium cavity 15, allowing the movable plate to move vertically within the medium cavity 15. Since the movable plate divides the medium cavity 15 into upper and lower chambers, the upper chamber of the medium cavity 15 can be used to contain the medium. When the movable plate moves, the bottom wall of the upper chamber moves upward, thus changing the center of gravity of the medium in the upper chamber, and consequently changing the center of gravity of the sphere 14.

[0040] If the center of gravity of the ball 14 is too low, on the one hand, when the installation channel 17 is tilted, it increases the risk of relative sliding between the ball 14 and the base. On the other hand, the bottom of the ball 14 has a large inertia, and the discharge channel 2 is prone to splashing liquid when the ball 14 is reset. By adjusting the position of the movable plate in the medium cavity 15, the position of the ball 14 can be adjusted so that the center of gravity of the ball 14 can be in a suitable position for easy use.

[0041] In embodiments of the present invention, the medium cavity 15 may be provided with a liquid inlet channel 21 for inputting the medium into the medium cavity 15.

[0042] In this embodiment of the invention, the sphere 14 may be provided with a push-pull ring 16, which is threaded to the sphere 14 and rotatably connected to the movable plate. The movable plate can be moved by rotating the push-pull ring 16.

[0043] The installation channel 17 can pass through the middle of the push-pull ring 16, so that the center of the movable plate can be located at the axis of the push-pull ring 16, making the force on the movable plate more even.

[0044] See Figure 3 , Figure 4 and Figure 5 In some embodiments, the movable plate includes a first plate body 23, a second plate body 22 and an elastic member 24. The edge of the first plate body 23 is provided with a sliding cavity, and the second plate body 22 is inserted into the sliding cavity. The first plate body 23 and the second plate body 22 divide the medium cavity 15 into two chambers, and the elastic member 24 is connected to the first plate body 23 and the second plate body 22.

[0045] In this embodiment, along the axis of the mounting channel 17, the cross-section of the medium cavity 15 can be trapezoidal, that is, in the side wall surface of the medium cavity 15, two opposite side wall surfaces are inclined surfaces that gradually converge from bottom to top.

[0046] Since the medium cavity 15 is arranged around the mounting channel 17, the medium cavity 15 includes an annular side wall, and the first plate 23 can be fitted over the annular side wall.

[0047] Sliding cavities can be provided on the two opposite sides of the first plate 23 and the medium cavity 15. Correspondingly, there are two second plates 22, which are inserted into the two sliding cavities respectively. The side of the second plate 22 away from the first plate 23 abuts against the inclined surface. The sliding cavities allow the area of ​​the movable plate to be changed, so that the movable plate can move up and down in the medium cavity 15.

[0048] The elastic element 24 is used to provide an elastic force to move the second plate 22 out of the sliding cavity, so that the first plate 23 and the second plate 22 can fit tightly against the side wall of the medium cavity 15, so that when the movable plate moves, the medium in the upper chamber will not flow into the lower chamber.

[0049] The elastic element 24 can be a spring.

[0050] In this embodiment of the invention, a sealing layer 25 is provided between the first plate 23 and the side wall of the medium cavity 15, between the second plate 22 and the side wall of the medium cavity 15, and on the inner wall of the sliding cavity, to increase the sealing effect.

[0051] The sealing layer 25 can be a suitable product selected from existing technologies.

[0052] See Figure 2 and Figure 3 In some embodiments, a steering component is also included, comprising a flexible channel 18 and a drive assembly, the flexible channel 18 being at least partially accommodated in the mounting channel 17, the discharge channel 2 passing through the flexible channel 18, and the drive assembly for bending the flexible channel 18.

[0053] The drive component enables the flexible channel 18 to bend, and consequently the discharge channel 2 located within the flexible channel 18 can also bend, making it easier to adjust the orientation of the discharge channel 2 so that the discharge channel 2 can discharge material into the tank.

[0054] The orientation adjustment range of the discharge channel 2 can be increased by adjusting the orientation of the discharge channel 2, so that the discharge channel 2 can discharge material to the liquid inlet of the tank.

[0055] In some embodiments, the flexible channel 18 is a corrugated pipe.

[0056] The corrugated pipe has a corrugated wall, which has good elasticity and flexibility, making it easy to bend by a drive assembly.

[0057] See Figure 2 and Figure 3 In some embodiments, the drive assembly includes a winding section 13 and a traction rope 19. The winding section 13 is used to wind up the traction rope 19. The winding section 13 is disposed at one end of the flexible channel 18. Along the axial direction of the flexible channel 18, a plurality of rope-passing sections 20 are provided at intervals on the side wall surface of the flexible channel 18. The rope-passing sections 20 are provided with rope-passing holes. One end of the traction rope 19 is wound into the winding section 13, and the other end passes through the rope-passing holes of the rope-passing sections 20 in sequence and is connected to the other end of the flexible channel 18.

[0058] The winding section 13 can be a suitable product selected from the existing technology, the structure and working principle of which are well known to those skilled in the art and will not be described in detail here.

[0059] When the winding section 13 winds up the traction rope 19, the traction rope 19 can pull the end of the flexible channel 18 connected to the traction rope 19 to bend, so that the flexible channel 18 can bend.

[0060] In this embodiment of the invention, there can be multiple driving components, and the traction ropes 19 of the multiple driving components can be arranged around the circumference of the flexible channel 18. Correspondingly, the circumference of the flexible channel 18 is also provided with a rope threading part 20, so that the flexible channel 18 can be bent in multiple directions. For example, two driving components can be symmetrically arranged, and the traction ropes 19 are respectively arranged on both sides of the flexible channel 18. When it is necessary to bend the flexible channel 18, the winding part 13 on the bending side winds up the traction rope 19, and the traction rope 19 on the opposite side unwinds.

[0061] See Figure 2 In some embodiments, the seat body includes a first sub-seat 9 and a second sub-seat 10, which are movably disposed on the loading platform 1, and a first surface and a second surface are disposed on the first sub-seat 9 and the second sub-seat 10, respectively.

[0062] The first auxiliary seat 9 and the second auxiliary seat 10 are movably mounted on the loading platform 1. On the one hand, they can adjust the position of the ball 14 as a whole. On the other hand, when the first auxiliary seat 9 and the second auxiliary seat 10 are closed, they can clamp the ball 14 to achieve the purpose of locking the ball 14.

[0063] The first auxiliary seat 9 and the second auxiliary seat 10 can be movably connected to the loading platform 1 via a connecting assembly. The connecting assembly includes a guide rod 11 and a lead screw 12. The guide rod 11 and the lead screw 12 are connected to the first auxiliary seat 9 or the second auxiliary seat 10 with their axes parallel to each other. The loading platform 1 is provided with a guide hole, through which the guide rod 11 passes. The lead screw 12 is rotatably connected to the first auxiliary seat 9 or the second auxiliary seat 10 and is threadedly connected to the loading platform 1. Rotating the lead screw 12 can achieve the purpose of driving the first auxiliary seat 9 or the second auxiliary seat 10 to move.

[0064] See Figure 1 In some embodiments, a liquid storage chamber 5 is also included, and the discharge channel 2 is connected to the liquid storage chamber 5.

[0065] The liquid storage chamber 5 is used to store materials to be discharged into the tank.

[0066] The liquid storage chamber 5 can be located above the loading platform 1 to facilitate the discharge of materials from the liquid storage chamber 5.

[0067] See Figure 1 In some embodiments, the discharge channel 2 is equipped with a valve 4 and a flow meter 3.

[0068] Valve 4 is used to open and close the discharge channel 2, making it easy to control the opening and closing of the discharge channel 2.

[0069] The flow meter 3 can count the amount of material discharged from the discharge channel 2.

[0070] See Figure 1 In some embodiments, the loading platform is provided with a cover 7 for sealing the lower pipe opening 8.

[0071] The cover 7 seals the lower pipe opening 8, reducing the risk of operators falling at the lower pipe opening 8 when the vehicle is not loaded.

[0072] See Figure 6 On the other hand, embodiments of the present invention also provide a method for safe loading of tank trucks, applied to the safe loading device for tank trucks in the above embodiments, including:

[0073] S1: Move the tank truck 6 below the loading platform 1 so that the inlet of the tank truck 6 is below the lower pipe port 8, making it easier for the operator to insert the discharge channel 2 into the liquid inlet of the tank from the lower pipe port 8.

[0074] S2: The orientation of the discharge channel 2 is adjusted by the steering component, so that the discharge channel 2 can discharge material into the feed port of the tank car 6 pipe. At the same time, the orientation of the discharge channel 2 can be further adjusted by the steering component, which increases the range of orientation adjustment of the discharge channel 2.

[0075] The above embodiments are merely preferred embodiments of the present invention / utility model and are not intended to limit the scope of the present invention / utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present invention / utility model without departing from the spirit of the present invention / utility model shall fall within the protection scope defined by the claims of the present invention / utility model.
