Description

Technical Field

[0001] This utility model relates to the field of packaging and transporting mullite powder, specifically a mullite powder bagging and transporting device. Background Technology

[0002] Mullite powder is a refractory material mainly composed of mullite. It has high refractoriness and stability. Mullite powder is usually used in the precision casting process of stainless steel. Its refractoriness is about 1750 degrees. Mullite powder is usually carried in bags for convenient sales and transportation.

[0003] When transporting existing mullite powder, the placement platform of the transport vehicle cannot be lowered, requiring workers to lift the mullite powder and place it into the transport equipment. This results in workers expending excessive physical strength during loading and unloading, thus reducing the efficiency of loading and unloading. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a mullite powder bag loading and transfer device, which has the following beneficial effects:

[0019] 1. This utility model, by setting up a hydraulic cylinder, a rotating shaft, and a first connecting rod, allows the hydraulic cylinder's output end to push a push rod connected to the first connecting rod forward when loading and unloading mullite powder bags is required. Since the first connecting rod is rotatably connected to the placement plate, the placement plate can rotate relative to the base plate. The push rod, which is fixedly connected to the first connecting rod, will drive the first connecting rod to rotate. As the first connecting rod rotates, the placement plate reaches a position closer to the ground, making it convenient for workers to load and unload the mullite powder bags. After loading and unloading, the hydraulic cylinder's output end is retracted to return the placement plate to a position farther from the ground. By lowering the placement plate position through the hydraulic cylinder, the worker's physical strength is effectively saved, solving the problem of low loading and unloading efficiency caused by excessive physical exertion.

[0020] 2. This utility model prevents the mullite powder bag from falling off during transportation by installing mesh baffles around the placement plate.

[0021] 3. This utility model uses two fixing buckles fixed on the base plate. The two fixing buckles are rotatably connected to the hydraulic cylinder through a pin. The fixing buckles and pin can fix the hydraulic cylinder and facilitate the replacement and maintenance of the hydraulic cylinder.

[0022] 4. This utility model has a foot installed at the bottom front end of the placement plate, which can support the placement plate on the ground when it is lowered.

[0023] 5. This utility model further includes a push-hand component at the rear end of the base plate. The push-hand component includes a pull rod and a handle. The pull rod is rotatably connected to the base plate via a pin, and the handle is fixed to the top of the pull rod. By installing the push-hand component at the rear end of the base plate, the transfer equipment can be controlled more conveniently.

[0024] 6. This utility model provides a slot at the front end of the base plate, and an extension plate is slidably installed inside the slot. The extension plate can maintain the balance of the transfer equipment after extension, ensuring that the equipment will not tip over when loading and unloading molybdenum powder bags.

[0025] 7. This utility model provides a slot at the rear end of the base plate, and a pedal is slidably installed inside the slot. The pedal can be stepped on when the device is pulled out, which can further ensure the balance of the transfer equipment.

[0026] 8. This utility model features a rotating shaft movably installed at the midpoint of the inner side of the two first connecting rods at the rear end of the base plate. A second connecting rod is rotatably connected to the rotating shaft, and the other end of the second connecting rod is fixedly connected to the extension plate. By fixing the extension plate to the rotating shaft installed on the inner side of the two first connecting rods at the rear end of the base plate, the second connecting rod will pull out the extension plate simultaneously when the placement plate descends, ensuring the balance of the transfer equipment during loading and unloading. It can also reduce the time for pulling out the extension plate and improve work efficiency.

[0027] 9. By installing a braking device on the caster, this utility model can fix the caster when it is necessary to load or unload the molybdenum powder bag, thereby improving the safety during transportation. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example: Please refer to Figures 1 to 4 According to an embodiment of the present utility model, a technical solution is provided: a mullite powder bag loading and transfer device, including a placement plate 1 and a base plate 2. The placement plate 1 and the base plate 2 are rotatably connected by multiple first connecting rods 3. A universal wheel 15 is installed at each of the four corners of the bottom of the base plate 2. A hydraulic cylinder 11 is rotatably connected to the left and right front ends of the base plate 2. The output end of the hydraulic cylinder 11 is rotatably connected to a push rod 12. The two ends of the push rod 12 are fixedly connected to the first connecting rods 3.

[0035] When implementing the above scheme, when it is necessary to transfer the mullite powder bags, the output end of the hydraulic cylinder 11 is driven to push the push rod 12, causing the first connecting rod 3 connected to the push rod 12 to rotate. Since the first connecting rod 3 is rotatably connected to the placement plate 1, the placement plate 1 can be raised and lowered. When the placement plate 1 is lowered to a position close to the ground, loading and unloading can be carried out. After loading and unloading, the transfer equipment can be pushed to the designated position by the casters 15 installed at the bottom of the base plate 2, which reduces the excessive consumption of manual labor and improves the efficiency of work.

[0036] Based on the above embodiments, baffles 4 are installed around the placement plate 1. The baffles 4 are set in a grid pattern. The baffles 4 can ensure that the mulberry powder bag in the placement plate 1 will not fall off during the transfer process, thereby improving the safety of the equipment.

[0037] Based on the above embodiments, the bottom of the hydraulic cylinder 11 is fixed by two fixing buckles 13. The fixing buckles 13 and the hydraulic cylinder 11 are rotatably connected by a pin 14. The rotatable connection of the pin 14 enables the hydraulic cylinder 11 to rotate, and the fixing buckles 13 and the pin 14 make it easier to install and disassemble the hydraulic cylinder 11, and better to carry out maintenance and replacement.

[0038] Based on the above embodiment, a foot 17 is installed at the bottom front end of the placement plate 1. The foot 17 can support the ground after the placement plate 1 is lowered, thereby improving the balance of the placement plate 1 and preventing it from tipping over after goods are placed on it, thus improving the safety of the equipment.

[0039] Based on the above embodiment, a push component is installed at the rear end of the base plate 2. The push component includes a pull rod 6 and a handle 7. The pull rod 6 is rotatably connected to the base plate 2 through a pin 8. The handle 7 is fixed at the top of the pull rod 6. By holding the handle 7, the transfer device can be moved.

[0040] Based on the above embodiment, a slot is provided at the front end of the base plate 2, and an extension plate 10 is slidably installed in the slot. A slot is also provided at the rear end of the base plate 2, and a pedal 9 is slidably installed inside the slot. The extension plate 10 can extend when the placement plate 1 is lowered to maintain the balance of the transfer equipment during loading and unloading. The pedal 9 can also extend during loading and unloading for workers to stand on, which can enhance the balance of the transfer equipment and increase the safety during loading and unloading.

[0041] Based on the above embodiment, a rotating shaft 5 is movably installed at the middle position of the inner side of the two first connecting rods 3 at the rear end of the base plate 2. A second connecting rod 16 is rotatably connected to the rotating shaft 5. The other end of the second connecting rod 16 is fixedly connected to the extension plate 10. The second connecting rod 16 connects the first connecting rod 3 and the extension plate 10. When the first connecting rod 3 is pushed down by the hydraulic cylinder 11, the end of the second connecting rod 16 connected to the extension plate 10 will push the extension plate 10 to extend, thereby maintaining the balance of the transfer equipment.

[0042] Based on the above embodiments, the caster wheel 15 is equipped with a braking device, which can restrict the rotation of the caster wheel 15 when the transfer equipment is loading and unloading, so that the caster wheel 15 is fixed in place, which can increase the safety of the equipment during the loading and unloading process.

[0043] Working principle: When loading and transferring mullite powder bags, this device first uses the braking device of the caster 15 to fix it in place to prevent slippage. Then, the hydraulic cylinder 11 pushes the push rod 12, which is rotatably connected to the output end, forward. At the same time, the first connecting rod 3 enables the placement plate 1, which is rotatably connected to it, to rotate relative to the base plate 2. This allows the height of the placement plate 1 to be adjusted. After lowering to a certain height, the feet 17 installed at the bottom of the placement plate 1 will press against the ground to support the placement plate 1. As the placement plate 1 lowers, the feet 17 installed at the middle position inside the last two first connecting rods 3... On the rotating shaft 5, the second connecting rod 16, which is rotatably connected to it, will push the extension plate 10, which is fixedly connected to the other end, to extend to maintain the balance of the equipment. Alternatively, the pedal 9 at the rear end of the base plate 2 can be pulled out for the worker to stand on to balance the equipment. After the worker puts the mullite powder bag into the placement plate 1 protected by the baffle 4, the hydraulic cylinder 11 is retracted to pull the placement plate 1 back to its original position. Then, the brake device is released to fix the caster wheel. By holding the pusher component installed at the rear end of the base plate 2, the transfer equipment is pushed to the loading location for loading. After arriving, the above steps are repeated to complete the unloading and loading of the mullite powder bag.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is limited by the appended claims and their equivalents.
