Description

Technical Field

[0001] This utility model relates to the field of methyltrichlorosilane raw material unloading arm conveying technology, specifically a methyltrichlorosilane raw material unloading arm conveying device. Background Technology

[0002] Loading arms are specialized equipment used for loading and unloading liquid or gaseous media, widely used in petrochemical, food, and pharmaceutical industries. They can be used for transporting methyltrichlorosilane raw materials. Existing loading arms often suffer from reduced load-bearing capacity when equipped with casters, and these casters are prone to damage after prolonged periods of heavy load. Furthermore, when stacking loading arms, the lack of upper baffles in most cases results in poor load-bearing capacity.

[0003] Regarding the aforementioned prior art, the inventor believes that the following shortcomings exist: The unloading arm conveying device, through the slider, movable rod, and No. 1 spring, can provide a high load-bearing capacity for the unloading arm, making it relatively practical. Through the No. 1 ventilation screen, motor, and fan, it achieves a good dust removal effect, making it even more practical. However, when the unloading arm conveying device is equipped with moving wheels, the load-bearing effect is mostly reduced, and the moving wheels are prone to damage after bearing load for a long time. When unloading arms need to be stacked, most unloading arms have poor load-bearing effect because they do not have baffles on the upper side. Utility Model Content

[0024] I. This utility model features a retractable structure. When the conveying device needs to be moved, the cylinder is activated, causing the piston to extend and retract. When the piston moves outward, it drives the connecting rod one to move downward in a circular motion along the rotating shaft three via the connecting block two.

When the connecting rod one and connecting rod two are in a straight line, the connecting rod two drives the moving wheel to lower and contact the ground via the rotating shaft five. When the conveying device needs to be placed at a fixed storage point, the operator activates the cylinder, causing... The piston rod retracts into the cylinder, and the piston rod drives the connecting rod one to move upward through the connecting block two. When the connecting rod one moves upward, it drives the connecting rod two to move upward at the same time. In turn, it drives the moving wheel to move clockwise along the rotating column through the connecting block seven. When the moving wheel moves to below the connecting rod one, it achieves the function of retracting the moving wheel. With the setting of the retractable structure, the conveying device is easy to move when it needs to change position. Moreover, when the moving wheel is retracted, the bottom frame of the conveying device contacts the ground, which does not affect the load-bearing capacity and stacking effect of the conveying device.

[0025] Second, based on the above-mentioned beneficial effects, a support structure is also provided. When the conveying devices need to be stacked, the operator can flip the support plate to cover the upper side of the enclosure. When the support plate covers the upper side, the operator can press down on the buckle body so that the buckle body is perpendicular to the ground and the fixing pin is perpendicular to the buckle body. When the buckle body is parallel to the support plate, the operator can insert the pin. The pin is fixed by the limiting pin, and finally achieves the effect of fixing the support plate. Through the setting of the support structure, a good support effect is achieved when the conveying devices need to be stacked on the upper side. Attached Figure Description

[0045] The retractable structure 2 also includes a first fixed plate 216, a second fixed plate 217, and a rotating column 218;

[0046] Fixed plate 216 is fixedly connected to one side of L-shaped connecting frame 201, fixed plate 217 is fixedly connected to the lower side of fixed plate 216, and rotating column 218 is movably connected to the inner cavity of fixed plate 217.

[0047] The rotating column 218 is square column-shaped, and rotating cylinders are provided on both sides of the rotating column 218. The rotating cylinders are movably connected to the inner cavity of the fixed plate 217.

[0048] The retractable structure 2 also includes a movable connecting shaft 1 219, a rotating shaft 6 220, a connecting rod 3 221, a rotating shaft 7 222, a connecting rod 4 223, a rotating shaft 8 224, a connecting block 6 225, and a movable connecting shaft 2 226;

[0050] The retractable structure 2 also includes a fixed rod 227, a connecting block 228, a rotating shaft column 229, a wheel connecting column 230, and a moving wheel 231;

[0051] The fixed rod 227 is fixedly connected to the lower side of the rotating column 218, the connecting block 228 is fixedly connected to one side of the fixed rod 227, the rotating shaft column 229 is movably connected to the inner cavity of the fixed rod 227, the wheel connecting column 230 is fixedly connected to the lower side of the rotating shaft column 229, and the movable wheel 231 is movably connected to one side of the wheel connecting column 230.

[0052] Connecting block 7 228 is connected to connecting block 5 214 via rotating shaft 5 215.

[0053] Working principle: When the conveying device needs to move, cylinder 204 is activated. Cylinder 204 drives piston 205 to extend and retract. When piston 205 moves outward, it drives connecting rod 210 to move downward along rotating shaft 208 via connecting block 206. When connecting rod 210 moves downward, it drives connecting rod 213 to move downward simultaneously via rotating shaft 212. When connecting rod 210 and connecting rod 213 are in a straight line, connecting rod 213 drives moving wheel 231 to lower via rotating shaft 215. When the conveying device touches the ground, and a fixed storage point needs to be placed, the operator activates cylinder 204, causing piston 205 to retract inward. Piston 205 drives connecting rod 210 upward via connecting block 206. When connecting rod 210 moves upward, it drives connecting rod 213 upward simultaneously, which in turn drives moving wheel 231 to move clockwise along rotating column 218 via connecting block 228. When moving wheel 231 moves below connecting rod 210, it achieves the function of retracting moving wheel 231.

[0054] In this step, the retractable structure 2 allows the conveying device to be moved easily when its position needs to be changed. When the moving wheels 231 are retracted, the bottom frame 1 of the conveying device contacts the ground, which does not affect the load-bearing capacity and stacking effect of the conveying device.

[0055] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, also includes a support structure 3.

[0056] A support structure 3 is fixedly connected to the upper side of the bottom frame 1;

[0060] Working principle: When the conveying devices need to be stacked, the operator can flip the support plate 304 to cover the upper side of the enclosure 301. When the support plate 304 covers the upper side, the operator can press down the buckle body 305 so that the buckle body 305 is perpendicular to the ground. The fixing pin 306 is perpendicular to the buckle body 305. When the buckle body 305 is parallel to the support plate 304, the operator can insert the pin 307. The pin 307 is fixed by the limiting pin 308, which finally achieves the effect of fixing the support plate 304. Through the setting of the support structure 3, a good support effect is achieved when the conveying devices need to be stacked on the upper side.
