Description

Technical Field

[0001] The present invention relates to the technical field of cargo loading and unloading platforms, and particularly to a structure of a cargo loading and unloading platform. Background Art

[0002] Petroleum drilling aid materials are indispensable functional materials in oil and gas exploration and development. Petroleum drilling aids include solid aid materials and liquid aid materials. Solid aids are usually used to provide physical support or plugging effects, while liquid aids are more used to adjust the chemical properties and rheological properties of drilling fluids. Petroleum drilling aids mainly cover various types such as filtration loss reducers, lubricants, bactericides, and plugging agents, which directly affect the performance of drilling fluids and the safety of wellbore operations. With the extension of global oil and gas resource development to deep earth, deep sea, and complex geological conditions, higher requirements are put forward for the storage management of aid materials;

[0003] However, when current staff members transport petroleum drilling aid materials into the warehouse for storage, in most cases, they rely solely on manual handling. This not only has low handling efficiency, but also due to the characteristics of high chemical activity and strong environmental sensitivity of such materials, when staff members handle these materials, the material performance is prone to deterioration due to problems such as temperature and humidity fluctuations and cross - contamination. Therefore, it is urgent to achieve precise control through a professional loading and unloading platform;

[0004] To solve the above problems, a structure of a cargo loading and unloading platform is proposed in this application. Summary of the Invention

[0005] The present invention aims to provide a structure of a cargo loading and unloading platform, mainly to solve the problems that currently, manual handling of petroleum drilling aid materials is required, which not only has low handling efficiency, but also the material performance is prone to deterioration due to problems such as temperature and humidity fluctuations and cross - contamination when staff members handle these materials.

[0006] To solve the above - mentioned technical problems, the present invention provides the following technical solutions:

[0007] A cargo loading and unloading platform structure includes a base. On one side of the bottom of the base, symmetric steering wheels are fixedly installed. A first rotating rod penetrates through the side of the base away from the steering wheels. Both ends of the first rotating rod extend out of the base and are fixedly connected to driving wheels, and the first rotating rod is rotatably connected to the base. A cavity is formed inside the base, and a driving component for rotating the first rotating rod is fixedly installed inside the cavity. A battery is fixedly installed on the top of the base. A lifting component is arranged on the top of the base. The top of the lifting component is connected to a lifting bracket. On one side of the top of the lifting bracket, a fixing plate is fixedly connected. A rotating shaft is rotatably connected to the top of the fixing plate. A placing platform is fixedly connected to the outer wall of the rotating shaft. A rotating component for tilting the placing platform is arranged on the top of the lifting bracket. A material blocking component for preventing the goods on the placing platform from falling is arranged on one side of the fixing plate. One side of the base is fixedly connected to a handrail, and a plurality of control buttons are installed on the handrail.

[0008] Working principle and beneficial effects of the present invention:

[0009] 1. Working principle: When the cargo loading and unloading platform is in use, the driving component inside the cavity can be controlled to operate through the control buttons on the handrail, so that the first rotating rod drives the driving wheels to rotate. By pulling the handrail, the steering of the loading and unloading platform can be controlled, thereby realizing the movement of the loading and unloading platform. After the loading and unloading platform moves to the designated position, the lifting component can be controlled to operate through the control buttons on the handrail, so that the lifting bracket drives the placing platform to rise or fall. When the placing platform is lowered to the lowest height, it is convenient for the staff to place goods on the placing platform. Through the material blocking component arranged on one side of the fixing plate, the goods on the placing platform can be better fixed. Then, after the device moves to the designated position, the placing platform is raised to a suitable height through the lifting component. By controlling the operation of the rotating component through the control buttons on the handrail, the placing platform can be in an inclined state, and then the staff can unload the goods on the placing platform onto the corresponding shelves inside the warehouse.

[0010] 2. Beneficial effects:

[0011] (1) When the loading and unloading platform is in use, the driving wheels can be rotated through the operation of the driving component inside the cavity, so that the device does not need to be pulled manually when moving, making the cargo transfer easier and more labor-saving.

[0012] (2) Through the lifting component arranged on the base, when the placing platform is lowered to the lowest height through the operation of the lifting component, it is convenient for the staff to place goods on the placing platform. After the device moves to the designated position inside the warehouse, the placing platform is leveled with the shelves through the operation of the lifting component, which is convenient for the staff to unload the goods on the placing platform onto the corresponding shelves inside the warehouse.

[0013] (3) Through the rotating component provided on the lifting bracket, when the placement platform is flush with the shelf, the rotating component can be operated to make the placement platform in an inclined state, which can make it easier for the staff to unload the goods.

The outer walls of the second rotating rod and the third rotating rod are provided with a control component. When the double-headed motor is started, under the action of the control component, the rotation of the second rotating rod can drive the first bevel gear to rotate synchronously. While the first bevel gear rotates, it can make the second bevel gear meshed with it rotate synchronously. The rotation of the second bevel gear can make the first rotating rod fixedly connected to it drive the two driving wheels to rotate synchronously, and the movement of the loading and unloading platform can be realized.

When the device is in use, starting the servo motor 44 can cause the second gear 45 to rotate. When the second gear 45 rotates, it can cause the toothed plate 42 meshed with it to drive the two second connecting rods 41 to move downward. When the teeth 50 on the sliding sleeve 37 inside the fixed sleeve 40 of the lower second connecting rod 41 are engaged with the tooth groove 51 on the first bevel gear 15, starting the double-headed motor 13 can cause the second rotating rod 14 to drive the first bevel gear 15 to rotate synchronously, thereby realizing the movement of the device. The servo motor 44 is a forward and reverse rotation motor. Controlling the reverse rotation of the servo motor 44 can cause the toothed plate 42 to drive the two second connecting rods 41 to move upward.

[0042] When the goods loading and unloading platform is in use, the operation of the servo motor 44 inside the cavity 5 can be controlled through the control button 12 on the handrail 11, so that the second gear 45 rotates. When the second gear 45 rotates, the toothed plate 42 meshed and connected with it can drive the two second connecting rods 41 to move downward. When the tooth 50 on the sliding sleeve 37 inside the fixed sleeve 40 on the lower second connecting rod 41 is engaged with the tooth groove 51 on the first bevel gear 15, the double-headed motor 13 is started to make the second rotating rod 14 rotate and drive the first bevel gear 15 to rotate synchronously. While the first bevel gear 15 rotates, the second bevel gear 16 meshed and connected with it can rotate synchronously. The rotation of the second bevel gear 16 can make the first rotating rod 3 fixedly connected with it drive the two driving wheels 4 to rotate synchronously. By pulling the handrail 11, the steering of the loading and unloading platform can be controlled, so as to realize the movement of the loading and unloading platform. After the loading and unloading platform moves to the designated position, controlling the reverse rotation of the servo motor 44 can make the toothed plate 42 drive the two second connecting rods 41 to move upward. When the tooth 50 on the lower sliding sleeve 37 disengages from the tooth groove 51 on the first bevel gear 15 and the tooth 50 on the upper sliding sleeve 37 is engaged with the tooth groove 51 at the bottom of the third bevel gear 18, the double-headed motor 13 is started, and the rotation of the third rotating rod 17 can drive the third bevel gear 18 to rotate synchronously. When the third bevel gear 18 rotates, it can drive the lead screw 20 to rotate through the fourth bevel gear 21 meshed and connected with it. The rotation of the lead screw 20 can drive the first connecting rod 54 to move through the threaded cylinder 53 threadedly connected with it. Through the first connecting rod 54, the two second U-shaped blocks 23 on the base 1 can be driven. While the second U-shaped blocks 23 move, the height of the placing platform 10 on the lifting support 7 can be adjusted through the two groups of cross lifting frames 26. When the placing platform 10 is lowered to the lowest height, it is convenient for the staff to place goods on the placing platform 10. The baffle 32 can effectively prevent the goods on the placing platform 10 from rolling down. Then, after the device moves to the designated position, when the placing platform 10 is raised to be flush with the shelf through the lifting assembly, the electric telescopic cylinder 31 is started through the control button 12 on the handrail 11 to make its length extend. When the length of the electric telescopic cylinder 31 extends, it will push the placing platform 10 to make it rotate, and the rotating shaft 9 on the fixed plate 8 will also rotate synchronously. While the rotating shaft 9 rotates, the first gear 35 can rotate synchronously. When the first gear 35 rotates, it can drive the baffle 32 to move downward through the rack 36 meshed and connected with it. After the placing platform 10 rotates to a certain angle, the baffle 32 will also drop a certain height at the same time, so as to facilitate the staff to unload the goods on the placing platform 10 onto the shelf. The advantage of such a setting is that it can make it more convenient for the staff to load and unload goods such as petroleum drilling aid materials.
