Description

Technical Field

[0001] The utility model relates to the field of chemical production, in particular to a safe unloading platform for chemical production. Background Art

[0002] Chemical engineering is an abbreviation for "chemical process," "chemical industry," or "chemical engineering." Any technology that uses chemical methods to change the composition or structure of a substance or to synthesize new substances is considered a chemical production technology, or chemical process. The resulting products are called chemicals or chemical products.

[0003] A search of the patent document with publication number CN221420035U revealed a "safe unloading platform for chemical production. This device is separated by a vertical opening of a clamping block and a clamping slot, allowing the positioning block to slide along the inner wall of the sleeve frame with the movable frame. This allows the unloading space between the sleeve frame and the movable frame to be changed and adjusted according to actual needs. This makes actual use simple and convenient, and improves the practicality of the device to a certain extent."

[0004] When the above-mentioned device is loading and unloading chemical materials, due to the long length of the device frame and the extension of the movable frame to expand the capacity of the device, when loading the above-mentioned device, the chemical materials need to be moved to the innermost part of the device frame first. When unloading the materials near the inner part of the frame, workers need to go inside the device to unload the materials, which is time-consuming and labor-intensive. If loading and unloading is carried out by loading and unloading equipment, the view of the frame is blocked, and the loading and unloading equipment is likely to knock over or tilt the internal material barrels, which may easily cause the chemical materials to leak or tip over when the device is moved. Utility Model Content

[0005] The purpose of this utility model is to provide a safe unloading platform for chemical production in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A safe unloading platform for chemical production, comprising a loading and unloading platform frame, a ground contact mechanism installed at the lower end of the loading and unloading platform frame, and a loading and unloading mechanism;

[0008] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0009] Preferably, the transmission structure is composed of two sprockets and chains meshed with the periphery of the sprockets, and the two sprockets of the transmission structure are respectively fixed to two extension shafts on the inner walls of the rear ends of the two fixing frames.

[0010] Preferably, the distance between two adjacent upper extension columns is twice the length of the connecting rod, the width of the top plate of the double-plate rack is greater than the width of the bottom plate of the double-plate rack, and the width of the bottom plate of the double-plate rack is less than the distance between two adjacent upper extension columns.

[0011] Preferably, the connecting rod is in a horizontal state, and the upper end of the upper extension column is flush with the upper end of the unloading plate.

[0012] Preferably, a through hole is provided on the top plate of the double-plate storage rack corresponding to the storage slot, and a handle is fixed on the upper end of the double-plate storage rack.

[0013] Preferably: the ground contact mechanism includes four universal wheels, which are respectively installed at the four corners of the lower end of the loading and unloading platform frame. The universal wheels have a self-locking structure. The lower end of the loading and unloading platform frame is rotatably connected to a screw. A limit rod is provided on one side of the screw, and the limit rod is fixed to the loading and unloading platform frame. A sliding cross plate is slidably connected to the outer periphery of the limit rod, and the sliding cross plate is threadedly connected to the screw, and a ground contact plate is fixed to the lower end of the sliding cross plate.

[0014] The beneficial effects compared with the prior art are as follows:

[0015] When the device needs to be operated, the chain drive of the transmission structure and the convex shafts at the front and rear ends of the horizontal rotating frame are connected to the four connecting rods. When the motor is started, the horizontal rotating frame can be kept in a horizontal state and rotated. When the horizontal rotating frame rises with the rotation, the upper extension column leaks out the upper end of the discharge plate, causing the upper extension column to rise and as the horizontal rotating frame rotates, the upper extension column will push the double-plate rack to the inside or outside of the loading and unloading platform frame. When the motor drives the connecting rod to rotate 360° in the forward direction, the motor stops driving, and the double-plate rack is pushed the distance between the two adjacent upper extension columns. Then a double-plate rack loaded with chemical materials is put in again. When the motor drives in the reverse direction, the double-plate rack is pushed out the distance between the two adjacent upper extension columns, so that multiple double-plate material racks can be located at the opening of the loading and unloading platform frame in sequence. In this way, the device can facilitate the loading and unloading of materials. BRIEF DESCRIPTION OF THE DRAWINGS

When the device moves to a suitable position, the self-locking structure of the universal wheels 11 is opened to prevent the universal wheels 11 from moving. Then, through the threaded connection between the sliding cross plate 14 and the screw 12 and the sliding connection between the limit rod 13 and the sliding cross plate 14, when the screw 12 is rotated, the touchdown plate 15 can be lowered, and the touchdown plate 15 contacts the ground to increase the touchdown area of the device, thereby making it less likely for the device to be displaced.

[0031] The loading and unloading mechanism includes two fixed frames 2, which are fixed to the bottom of the loading and unloading platform frame 1. The inner walls of the front and rear ends of the two fixed frames 2 are rotatably connected to extension shafts 21. A motor 22 is installed at the input end of one of the extension shafts 21. A transmission structure 23 is installed between the two extension shafts 21 located on the inner walls of the rear ends of the two fixed frames 2. The transmission structure 23 is composed of two sprockets and a chain meshed with the outer periphery of the sprockets. The two sprockets of the transmission structure 23 are respectively fixed to the two extension shafts 21 on the inner walls of the rear ends of the two fixed frames 2. The outer periphery of each extension shaft 21 is fixed to the two extension shafts 21. The four connecting rods 24 are fixed with connecting rods 24, and a horizontal rotating frame 25 is provided between the four connecting rods 24. The front and rear ends of the horizontal rotating frame 25 are provided with convex shafts, and each convex shaft is rotatably connected to the corresponding connecting rod 24. The upper end of the horizontal rotating frame 25 is fixed with multiple upper extension columns 26. The distance between two adjacent upper extension columns 26 is twice the length of the connecting rod 24. A discharge plate 27 is fixed to the inner wall of the loading and unloading platform frame 1, and the upper end surface of the discharge plate 27 is provided with multiple long strip grooves. The connecting rod 24 is in a horizontal state, the upper end of the upper extension column 26 is flush with the upper end of the discharge plate 27, and the discharge plate 27 is fixed with a plurality of long strip grooves. A plurality of springs 28 are fixed inside the , a round head 29 is fixed on the upper end of the spring 28, a plurality of protrusions 210 are fixed on the upper end of one side of the unloading plate 27, a double-plate rack 211 is provided above the unloading plate 27, and the front and rear ends of the double-plate rack 211 are slidably connected to the inner wall of the loading and unloading platform frame 1, the width of the top plate of the double-plate rack 211 is greater than the width of the bottom plate of the double-plate rack 211, the width of the bottom plate of the double-plate rack 211 is less than the distance between the two adjacent upper extension columns 26, the bottom of the double-plate rack 211 is provided with a storage groove 212, the double-plate rack A through hole is provided in the top plate of the rack 211 corresponding to the storage slot 212, and a handle is fixed to the upper end of the double-plate storage rack 211; it is rotatably connected to the four connecting rods 24 through the chain drive of the transmission structure 23 and the convex shafts at the front and rear ends of the horizontal rotating frame 25. When the motor 22 is started, the horizontal rotating frame 25 can be kept in a horizontal state and rotated. When the horizontal rotating frame 25 rises with the rotation, the upper extension column 26 will leak out of the upper end of the discharge plate 27, so that the two upper extension columns 26 located at the opening of the loading and unloading platform frame 1 will push the double-plate storage rack 211 into the interior of the loading and unloading platform frame 1.

[0032] Working Principle: When the device is in operation, the universal wheel 11 is first used to move the device to a suitable position, and the self-locking structure of the universal wheel 11 is opened to prevent the universal wheel 11 from moving. Then, the sliding cross plate 14 is threadedly connected to the screw rod 12, and the limiting rod 13 is slidably connected to the sliding cross plate 14. When the screw rod 12 is rotated, the contact plate 15 is lowered. The contact plate 15 contacts the ground, increasing the contact area of the device, thereby preventing the device from being displaced.

[0033] When the device needs to be loaded, first put the prepared chemical material barrel into the storage slot 212 of the double-plate rack 211, then lift the double-plate rack 211 and align it with the groove on the inner wall of the loading and unloading platform frame 1 and slide it into the double-plate rack 211. After pushing the double-plate rack 211 into the device, the double-plate rack 211 will hit the round head 29 and be blocked. At this time, the pushing of the double-plate rack 211 is stopped and the motor 22 is started. Through the chain drive of the transmission structure 23 and The convex shafts at the front and rear ends of the horizontal rotating frame 25 are rotatably connected to the four connecting rods 24. When the motor 22 is started, the horizontal rotating frame 25 can rotate in a horizontal state. When the horizontal rotating frame 25 rises with the rotation, the upper extension column 26 will leak out the upper end of the discharge plate 27, so that the two upper extension columns 26 located at the opening of the loading and unloading platform frame 1 will push the double-plate rack 211 into the interior of the loading and unloading platform frame 1. In this process, due to the elasticity of the spring 28, the double-plate rack 211 passes through the round head 29. When the round head 29 is pressed into the discharge plate 27, the motor 22 drives the connecting rod 24 to rotate 360 degrees, and then the motor 22 stops driving. The distance that the double-plate rack 211 is pushed is the distance between the two adjacent upper extension columns 26. At this time, the other double-plate rack 211 loaded with chemical material barrels is lifted and the above operation is repeated until the upper end of the discharge plate 27 is full. Since the width of the top plate of the double-plate rack 211 is greater than the width of the bottom plate, after the double-plate rack 211 is full, the two adjacent double-plate racks are The top plates of the double-plate racks 211 fit together, and a certain gap is left between the bottom plates of two adjacent double-plate racks 211. Then the motor 22 is driven again with a small amplitude to make the upper extension column 26 leak out a small section of the discharge plate 27 and press against the corresponding double-plate rack 211. One end of the double-plate rack 211 loaded into the device first presses against the protrusion 210. In this way, all loaded double-plate racks 211 are fixed, so that the double-plate racks 211 will not be displaced when the device is moved.

[0034] When unloading is required, the motor 22 is first driven in the reverse direction with a small amplitude to make the upper end of the upper extension column 26 flush with the upper end of the discharge plate 27, so that the double-plate rack 211 closest to the opening of the loading and unloading platform frame 1 is not restricted, and the double-plate rack 211 close to the opening of the loading and unloading platform frame 1 is removed. Then the motor 22 is driven in the reverse direction 360° again, so that all the double-plate racks 211 in the device can be pushed a distance toward the opening of the loading and unloading platform frame 1. In this way, multiple double-plate racks 211 in the device can be pushed to the opening of the loading and unloading platform frame 1 in turn, thereby facilitating their unloading.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
