Description

Technical Field

[0001] This utility model relates to the field of transfer trolley technology, and in particular to a chemical storage tank transfer trolley with a positioning structure. Background Technology

[0002] In the chemical production and logistics sector, chemical storage tanks, as core equipment for storing and transporting liquid or gaseous chemicals, directly impact production continuity and environmental safety with their safety and transportation efficiency. Traditional chemical storage tank transfer tools generally suffer from the following technical defects: Existing transfer trolleys mostly employ fixed clamps or support structures, making dynamic adjustment impossible based on parameters such as the tank's height and diameter. For example, when transporting different tank models, specialized clamps must be replaced or the trolley structure adjusted, leading to complex operations, longer processing times, and increased equipment costs. Furthermore, fixed designs are ill-suited to irregular tank surfaces or dimensional deviations, easily causing insecure clamping or localized stress concentration, increasing transportation risks. Traditional trolleys lack effective shock absorption and limiting structures; impacts from road bumps, sudden stops, or turns during transport can cause tank displacement, overturning, or collisions with the trolley. Especially for flammable, explosive, or corrosive chemicals, even minor tank displacement can trigger seal failure, leading to leaks or even explosions, seriously threatening operator safety and the environment. In addition, rigid connection structures cannot absorb vibration energy, easily causing fatigue damage over long-term use, further reducing reliability. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a chemical storage tank transfer trolley with a positioning structure, which more accurately solves the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a chemical storage tank transfer trolley with a positioning structure, including a discharge plate. A U-shaped frame is installed on the top of the discharge plate, and multiple support rods are installed on the inner wall of the U-shaped frame. An arc-shaped rod is provided on the top of the discharge plate at a symmetrical position to the U-shaped frame, and a clamping component is installed on the arc-shaped rod for clamping the workpiece. A support part is provided on the top of the discharge plate for adjusting the height of the arc-shaped rod and driving the arc-shaped rod to rotate. The support part includes a support rod one installed on the top of the discharge plate, a support rod two provided on the top of the support rod one, a spring cylinder installed between the support rod one and the support rod two, and a limit plate installed on the top of the support rod two, with the limit plate in contact with the top of the workpiece.

[0006] Preferably, both the first support rod and the second support rod are provided with an adjustment part, which is used to adjust the position of the arc-shaped rod and to limit the arc-shaped rod after it rotates around the first support rod and the second support rod.

[0007] Preferably, the adjusting part includes a threaded sleeve installed on the surfaces of support rod one and support rod two, and a threaded cylinder is installed at the end of the arc-shaped rod, with the threaded sleeve and the threaded cylinder being threadedly connected.

[0008] Preferably, a bracket is installed on the back of the feeding plate, a moving wheel is installed on the bracket, and an inclined plate is installed on the side of the feeding plate for moving the workpiece to the top of the feeding plate.

[0009] Preferably, the clamping member includes a threaded seat mounted on the surface of the arc-shaped rod, a lead screw is threadedly connected to the inner wall of the threaded seat, and a clamping plate is rotatably connected to the end of the lead screw via a bearing. The side of the clamping plate contacts the workpiece for clamping the workpiece.

[0010] Preferably, a guide rod is installed on the side of the clamping plate, and the guide rod is connected through the arc-shaped rod.

[0011] Compared with the prior art, this utility model provides a chemical storage tank transfer trolley with a positioning structure, which has the following advantages:

[0012] This chemical storage tank transfer trolley with a positioning structure can adapt to chemical storage tanks of different heights and diameters through the elastic adjustment of the support and the precise positioning of the clamping components. The combination of the support rod and the spring cylinder can dynamically adjust the position of the arc-shaped rod according to the height of the storage tank, and also buffer transportation vibrations to avoid damage to the storage tank or equipment caused by rigid impacts. The clamping components, through the synergistic action of the lead screw and guide rod, achieve uniform clamping force distribution without deflection, ensuring that the storage tank remains stable and without displacement even in complex road conditions.

[0013] This chemical storage tank transfer trolley with a positioning structure significantly simplifies the tank loading and unloading process through a combination of a rotatable arc-shaped rod and a ramp structure. Operators simply push the tank along the ramp to the discharge plate, rotate the arc-shaped rod to the side of the tank, and quickly lock it in place using the adjustment mechanism. The screw-driven clamping plate clamps and releases via rotation, requiring no additional tools and allowing for operation by a single person. Attached Figure Description

Detailed Implementation

[0019] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0020] Example

[0021] like Figures 1-4 As shown in the figure, an embodiment of this utility model proposes a chemical storage tank transfer trolley with a positioning structure, including a discharge plate 1, on the top of which a U-shaped frame 2 is fixedly installed. Multiple support rods 3 are evenly spaced on the inner wall of the U-shaped frame 2 to support the bottom of the storage tank. An arc-shaped rod 5 is positioned symmetrically on the top of the discharge plate 1 at the U-shaped frame 2, and a clamping element 6 is installed on the arc-shaped rod 5. The support part 4 includes a support rod 41 fixed to the discharge plate 1, whose top is movably connected to a support rod 42 via a spring cylinder 43. A limiting plate 44 is installed on the top of the support rod 42. By adjusting the height of the support rod 42, the arc-shaped rod 5 drives the clamping element 6 to rise and fall, adapting to storage tanks of different heights. The support part 4 uses the spring cylinder 43 to buffer transport vibrations, and the limiting plate 44 fits against the top of the storage tank to prevent longitudinal displacement. The arc-shaped rod 5 and the clamping element 6, together with the support rods 3, achieve lateral clamping, ensuring the storage tank is stable and does not shake during transport, reducing the risk of leakage.

[0022] In this invention, adjustment parts 9 are provided on the surfaces of support rod 1 41 and support rod 2 42 for limiting the rotation of the arc-shaped rod 5. Initially, the arc-shaped rod 5 can rotate around support rod 1 41 and support rod 2 42, facilitating loading and unloading of the storage tank. After loading, the position of the arc-shaped rod 5 is fixed by the adjustment parts 9 to prevent loosening during transportation. The adjustment parts 9 allow the arc-shaped rod 5 to rotate flexibly during loading and unloading of the storage tank, avoiding interference. During transportation, the limiting mechanism ensures that the clamping part 6 fits tightly against the storage tank, balancing ease of operation and transportation stability.

[0023] In this invention, the adjusting part 9 includes a threaded sleeve 91 and a threaded cylinder 92. The threaded sleeve 91 is fixed to the surfaces of support rod 41 and support rod 42, and the threaded cylinder 92 is installed at the end of the arc-shaped rod 5. The two are connected by threads. Rotating the threaded cylinder 92 can adjust the tightness of the arc-shaped rod 5 to achieve a limiting function. The threaded connection method is simple to operate, has high adjustment accuracy, ensures that the arc-shaped rod 5 does not shift during transportation, and facilitates quick release of the limiting function for the next loading and unloading.

[0024] In this invention, a support bracket 7 is fixedly installed on the back of the material discharge plate 1, and a movable wheel 8 is installed at the bottom of the support bracket 7 to facilitate the movement of the trolley. An inclined plate is provided on the side of the material discharge plate 1, and the storage tank can roll to the top of the material discharge plate 1 through the inclined plate, reducing the intensity of manual handling. The combination design of the movable wheel 8 and the inclined plate significantly improves loading and unloading efficiency and reduces labor costs. At the same time, the trolley can flexibly shuttle between production workshops or warehouses, improving logistics efficiency.

[0025] In this invention, the clamping component 6 includes a threaded seat 61 fixed to the arc-shaped rod 5, with a lead screw 62 threadedly connected to its inner wall. The end of the lead screw 62 is rotatably connected to a clamping plate 63 via a bearing. Rotating the lead screw 62 can push the clamping plate 63 to move radially along the arc-shaped rod 5, thereby clamping the storage tank. The lead screw-driven clamping plate 63 can adapt to storage tanks of different diameters, and the clamping force is evenly distributed, avoiding excessive local pressure that could cause deformation of the storage tank, while also ensuring that the storage tank does not shift during transportation.

[0026] In this invention, a guide rod 64 is fixedly installed on the side of the clamping plate 63. The guide rod 64 passes through the arc-shaped rod 5 and can slide freely. The guide rod 64 is arranged parallel to the lead screw 62, restricting the rotational freedom of the clamping plate 63 and ensuring that it moves only radially. The guide rod 64 prevents the clamping plate 63 from deflecting when the lead screw 62 rotates, ensuring the stability and reliability of the clamping action, extending the service life of the clamping component 6, and reducing maintenance costs.
