Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguisher cylinder processing, in particular to a lifting machine for dispersing upper and lower heads of fire extinguisher cylinders. Background Art

[0002] The fire extinguisher cylinder is one of the most important pressure-bearing components of the pressure vessel, and its inner diameter and volume often need to be determined by process calculations. Cylindrical cylinders (i.e., cylinders) and spherical cylinders are the most commonly used cylinder structures in engineering. When assembling the fire extinguisher cylinder, the cylinder needs to be assembled and welded with the upper and lower heads, so a feeding device is needed for feeding.

[0003] For example, publication number CN203461480U discloses a material selection device for a cylinder head of a fire extinguisher, comprising a material storage mechanism, a rubbing plate mechanism, a drum sorting mechanism and a slide direction identification and flipping mechanism, the material storage mechanism comprises a hopper and a hopper bracket, the rubbing plate mechanism comprises a left rubbing plate, a right rubbing plate and a rubbing plate driving motor, the rubbing plate driving motor is fixed to the material plate bracket, the left rubbing plate and the right rubbing plate are installed on the lower right side of the hopper; the material discharge port of the hopper is connected to the inlet of the drum inlet slide, and the outlet of the drum inlet slide is connected to the material inlet of the drum; the material discharge port of the drum is connected to the upper slide; the slide direction identification and flipping mechanism comprises an upper slide, a flip slide and a lower slide, and the upper slide, flip slide and lower slide are installed on the drum bracket in sequence.

[0004] However, in the prior art, during the feeding process, the upper and lower heads are easily stacked freely in the hopper, which results in that when the heads are transported to the cylinder welding platform, the multiple heads on the platform are close to each other and cannot be directly welded. In order to solve this problem, the operator needs to add a separation step before welding, that is, to separate the stacked heads one by one manually or using tools to ensure that each head can be independently and clearly presented on the welding platform. This additional separation step not only increases the complexity of the operation, but also significantly reduces the overall welding efficiency. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that the sealing heads are easily stacked freely in the hopper, and proposes a lifting machine for dispersing the upper and lower sealing heads of a fire extinguisher cylinder.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: the upper and lower heads of the fire extinguisher cylinder are dispersed by a lifting machine, including a lifting frame, a hopper is fixedly connected to one side of the bottom end of the lifting frame, a chain is arranged on the inner side of the lifting frame, a lifting plate is installed on the outer side of the chain, an inclined plate is fixedly connected to the center of one side of the lifting plate, and a connecting frame is fixedly connected to the other side of the lifting plate, an intermediate plate is arranged below the inclined plate, the intermediate plate is fixedly connected to the lifting plate, two limit rods are symmetrically fixedly connected to one side of the lifting frame, the limit rods are located above the hopper, two limit plates are symmetrically fixedly connected to the top of one side of the lifting frame, support rods are fixedly connected to both sides of the chain, the chain is located on the inner side of the connecting frame, and the support rods are plugged into the connecting frame.

[0007] Preferably, the middle plate is located between two limiting rods, and the inclined plate is obliquely installed on one side of the lifting plate.

[0008] Preferably, a fixing frame is fixedly connected to the side wall of the limiting plate, and one end of the fixing frame is fixedly connected to the side wall of the lifting frame by bolts.

[0009] Preferably, a driving motor is fixedly mounted on the bottom end of one side of the lifting frame, and a bearing is fixedly connected to the output end of the driving motor.

[0010] Preferably, a sprocket is fixedly connected to the outer surface of the bearing, and sprockets are meshedly connected to the inner sides of both ends of the chain.

[0011] Preferably, one of the sprockets is fixedly connected to the active rod, and the inner side of the other sprocket is fixedly connected to a driven rod.

[0012] Preferably, both ends of the sprocket and the active rod are rotatably connected with bearings, and the bearings are fixedly connected to the lifting frame.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, the upper and lower heads of the fire extinguisher cylinder can be separated one by one and stacked in order on the lifting plate in a highly automated and precise manner. As the lifting plate gradually rises, no accumulation occurs between the workpieces, ensuring the smoothness and efficiency of the loading process. At the same time, by precisely controlling the movement of the lifting plate, the workpieces are effectively prevented from falling during the lifting and conveying process, thereby ensuring the safety and stability of production.

[0015] 2. In the utility model, the coordinated work of the active rod, sprocket and chain ensures that multiple lifting plates can move continuously and stably, thereby realizing the automatic transportation of workpieces. During the transportation process, the middle plate not only passes through the limit rod smoothly, but also effectively separates the tools on the side of the lower lifting plate, avoiding mutual interference and accumulation between workpieces.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1

[0024] like Figure 1 , Figure 2 and Figure 4As shown, the utility model provides a lifting machine for dispersing the upper and lower heads of a fire extinguisher cylinder, including a lifting frame 1, a hopper 2 is fixedly connected to one side of the bottom end of the lifting frame 1, a chain 35 is arranged on the inner side of the lifting frame 1, a lifting plate 4 is installed on the outer side of the chain 35, an inclined plate 41 is fixedly connected to the center of one side of the lifting plate 4, and a connecting frame 43 is fixedly connected to the other side of the lifting plate 4, an intermediate plate 42 is arranged below the inclined plate 41, the intermediate plate 42 is fixedly connected to the lifting plate 4, two limit rods 5 are symmetrically fixedly connected to one side of the lifting frame 1, the limit rods 5 are located above the hopper 2, two limit plates 6 are symmetrically fixedly connected to the top of one side of the lifting frame 1, support rods 351 are fixedly connected to both sides of the chain 35, the chain 35 is located on the inner side of the connecting frame 43, and the support rods 351 are plugged into the connecting frame 43.

[0025] The following is a detailed description of the specific settings and functions of this embodiment. First, the upper and lower heads of the fire extinguisher cylinder are stacked in the hopper 2. When the chain 35 is active, the connecting frame 43 is moved by the support rod 351, thereby changing the position of the lifting plate 4. When the lifting plate 4 passes through the inside of the hopper 2, it will automatically separate the workpieces stacked inside the hopper 2 one by one, ensuring that a single workpiece can be neatly stacked on the inclined plate 41 on the surface of the lifting plate 4. As the lifting plate 4 is gradually lifted, the presence of the two limit rods 5 ensures that the gap between them and the lifting plate 4 can accommodate a single workpiece, avoiding the accumulation of workpieces during the lifting process. At the same time, when the lifting plate 4 continues to move, it will be restricted by the limit plate 6, so that the workpiece is always kept inside the limit plate 6 during the loading and lifting process, ensuring that the workpiece will not fall during the process of being transported to the cylinder welding platform. In this way, the system realizes the gradual, orderly and safe loading process of the fire extinguisher cylinder workpiece.

[0026] Embodiment 2

[0027] like Figure 3 and Figure 4 As shown, the middle plate 42 is located between the two limit rods 5, and the inclined plate 41 is obliquely installed on one side of the lifting plate 4. The side wall of the limit plate 6 is fixedly connected with a fixing frame 7, and one end of the fixing frame 7 is fixedly connected to the side wall of the lifting frame 1 by bolts. A driving motor 3 is fixedly installed at the bottom end of one side of the lifting frame 1, and a bearing 33 is fixedly connected to the output end of the driving motor 3. A sprocket 32 ​​is fixedly connected to the outer surface of the bearing 33, and the inner sides of both ends of the chain 35 are meshed and connected with the sprocket 32. One of the sprockets 32 is fixedly connected to the active rod 31, and the inner side of the other sprocket 32 ​​is fixedly connected to the driven rod 34. Both ends of the sprocket 32 ​​and the active rod 31 are rotatably connected with bearings 33, and the bearing 33 is fixedly connected to the lifting frame 1.

[0028] The effect achieved by the entire embodiment is that when the driving motor 3 is running, it will drive the active rod 31 to rotate. The rotation of the active rod 31 will further drive the sprocket 32 ​​on its surface to rotate, thereby triggering the movement of the chain 35. When the chain 35 starts to move, the sprocket 32 ​​on the inner side of the top will also rotate accordingly, which makes the driven rod 34 start to rotate. Therefore, during the rotation of the driven rod 34 and the active rod 31, the chain 35 will continue to move, thereby driving the multiple lifting plates 4 to move continuously. During the conveying process, the middle plate 42 will pass between the two limit rods 5. At the same time, the existence of the middle plate 42 effectively separates the tools on one side of the lower lifting plate 4, ensuring smooth and stable conveying of the workpiece.

[0029] The method of use and working principle of the device: First, the upper and lower heads of the fire extinguisher cylinder are stacked in the hopper 2. When the drive motor 3 is running, it drives the active rod 31 to rotate. The rotation of the active rod 31 will further drive the sprocket 32 ​​on its surface to rotate, thereby triggering the movement of the chain 35. When the chain 35 starts to move, the sprocket 32 ​​on the inner side of the top will also rotate accordingly, which causes the driven rod 34 to start rotating. Therefore, during the rotation of the driven rod 34 and the active rod 31, the chain 35 will continue to move, and the connecting frame 43 will move through the drive of the support rod 351, thereby changing the position of the lifting plate 4. When the lifting plate 4 passes through the inside of the hopper 2, it will automatically separate the workpieces stacked inside the hopper 2 one by one, ensuring that a single workpiece can be neatly stacked on the inclined plate 41 on the surface of the lifting plate 4. As the lifting plate 4 is gradually lifted, the presence of the two limit rods 5 ensures that the gap between them and the lifting plate 4 can accommodate a single workpiece, avoiding the accumulation of workpieces during the lifting process. At the same time, when the lifting plate 4 continues to move, it will be limited by the limit plate 6, so that the workpiece is always kept inside the limit plate 6 during the loading and lifting process, ensuring that the workpiece will not fall during the process of being transported to the cylinder welding platform. In this way, the system realizes the gradual, orderly and safe loading process of the fire extinguisher cylinder workpiece.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
