Description

Technical Field

[0001] This utility model relates to the field of steel cylinders, and in particular to a rapid filling mechanism for steel cylinders. Background Technology

[0002] A gas cylinder is a sealed container used to store and transport compressed gases, liquefied gases, or high-pressure liquids. It is usually made of high-strength steel or other pressure-resistant materials and is widely used in many fields such as industry, medical care, fire protection, food, and energy.

[0003] A cylinder rapid filling mechanism is a device used to achieve rapid and automated filling of cylinders.

[0004] The existing rapid filling mechanism for steel cylinders has the following shortcomings: Currently, oxygen cylinder filling operations generally rely on manual labor for cylinder transfer and handling. Workers must first move the heavy oxygen cylinders from the storage area to the filling equipment, and then painstakingly adjust their positions before proceeding with subsequent operations. After filling, the cylinders must be manually moved down from the filling station. The entire process consumes a lot of manpower and time. This model is not only labor-intensive and inefficient, making it difficult to meet the needs of batch filling, but also prone to collisions during manual handling. Utility Model Content

[0005] This invention achieves automatic conveying of gas cylinders through the coordinated operation of a slider and a transverse plate, effectively replacing manual handling and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a rapid filling mechanism for steel cylinders, including a conveying mechanism, with a filling component fixedly installed on the top of the conveying mechanism; the conveying mechanism includes a fixed plate, a slider slidably connected to the inner wall of the fixed plate, a transverse plate fixedly connected to the top of the slider, a set of first electric push rods fixedly installed on the inner wall of the transverse plate, a set of clamping blocks fixedly connected to the shaft end of the first electric push rods, rubber pads fixedly connected to the inner walls of the clamping blocks, a threaded rod movably inserted into the inner wall of the fixed plate, and a servo motor fixedly installed on one side of the outer wall of the fixed plate. Through the above components, the transverse plate automatically conveys the steel cylinders, eliminating the need for manual handling and reducing labor intensity.

[0007] Preferably, each of the fixed plates has a support plate fixedly connected to its bottom, and each of the support plates has an anti-slip pad fixedly connected to its bottom. A PLC controller is fixedly installed on one side of the front of the fixed plate, and an oxygen cylinder is provided on the outer wall of the clamping block. The PLC controller can centrally control the operation of each component of the equipment, eliminating the need for manual operation and simplifying the process.

[0008] Preferably, a set of guide blocks are slidably connected to the inner wall of the fixed plate. The top of the guide blocks is fixedly connected to the bottom of the transverse plate. The guide blocks provide guidance for the movement of the transverse plate and prevent the transverse plate from deviating during the delivery of oxygen cylinders.

[0009] Preferably, a set of guide rods is fixedly connected to the inner wall of the fixed plate, the outer wall of the guide rods is slidably connected to the inner wall of the guide block, the inner wall of the clamping block is V-shaped to form a V-groove, and the guide rods cooperate with the guide block to restrict the movement direction of the transverse plate.

[0010] Preferably, an encoder is fixedly installed on the inner wall of the fixed plate, the output end of the servo motor is fixedly connected to one end of the threaded rod, the outer wall of the encoder is fixedly connected to the other end of the threaded rod, and the thread of the outer wall of the threaded rod penetrates the inner wall of the slider. The encoder can monitor the number of rotations of the threaded rod in real time, thereby calculating the moving distance of the transverse plate and feeding the data back to the control system to achieve precise control of the oxygen cylinder delivery position.

[0011] Preferably, the filling assembly includes a connecting plate, a second electric push rod is fixedly installed on the inner wall of the connecting plate, a lifting block is fixedly connected to the shaft end of the second electric push rod, a filling head is fixedly installed on the inner wall of the lifting block, and a nut is threadedly connected to the outer wall of the filling head. The second electric push rod drives the lifting block to move the filling head up and down, automatically completing the docking of the filling head with the oxygen cylinder.

[0012] Preferably, the top of the filling head is fixedly connected to an air inlet pipe, and the top of the connecting plate is fixedly connected to a supporting cylinder. The inner wall of the supporting cylinder is slidably connected to the outer wall of the air inlet pipe. The supporting cylinder guides and supports the air inlet pipe to prevent it from shaking when the filling head is raised and lowered.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the conveying mechanism adopts a servo motor to drive the threaded rod, and the slider and the transverse plate work together to realize the automatic conveying of the steel cylinder, effectively replacing manual handling and significantly reducing labor intensity. The first electric push rod precisely controls the clamping block to clamp the steel cylinder. With the rubber pad on the inner wall of the clamping block, it can not only prevent the surface of the steel cylinder from being bumped and damaged, but also ensure that the conveying process is stable and reliable and does not deviate. At the same time, the PLC controller centrally controls each execution component, which simplifies the operation process, reduces human operation errors, improves the system operating efficiency, and fully meets the high efficiency and stability requirements of batch filling operations.

[0014] 2. In this utility model, the guide block and guide rod work together to provide double guidance for the movement of the transverse plate, effectively preventing the cylinder from shifting during transportation. The encoder monitors the rotation angle of the threaded rod in real time and accurately calculates the displacement position of the transverse plate to achieve high-precision positioning of the cylinder. In the filling assembly, the second electric push rod drives the filling head to automatically lift and lower, completing a quick and accurate docking with the cylinder. The supporting cylinder provides stable support and guidance for the air inlet pipe, avoiding the impact of pipeline shaking on filling stability and safety during gas transportation.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a rapid filling mechanism for steel cylinders, including a conveying mechanism 1, with a filling component 2 fixedly installed on the top of the conveying mechanism 1; the conveying mechanism 1 includes a fixed plate 101, a slider 111 slidably connected to the inner wall of the fixed plate 101, a transverse plate 102 fixedly connected to the top of the slider 111, a set of first electric push rods 112 fixedly installed on the inner wall of the transverse plate 102, a set of clamping blocks 113 fixedly connected to the shaft end of the first electric push rods 112, rubber pads 114 fixedly connected to the inner walls of the clamping blocks 113, a threaded rod 108 movably inserted into the inner wall of the fixed plate 101, and a servo motor 105 fixedly installed on one side of the outer wall of the fixed plate 101. Through the above components, the transverse plate 102 automatically conveys the steel cylinders without manual handling, reducing labor intensity.

[0020] like Figure 2 As shown, a support plate 104 is fixedly connected to the bottom of the fixed plate 101, and an anti-slip pad 106 is fixedly connected to the bottom of the support plate 104. A PLC controller 103 is fixedly installed on one side of the front of the fixed plate 101. An oxygen cylinder 3 is provided on the outer wall of the clamping block 113. The PLC controller 103 can centrally control the operation of each component of the equipment, eliminating the need for manual operation and simplifying the process.

[0021] like Figure 3 As shown, a set of guide blocks 109 are slidably connected to the inner wall of the fixed plate 101. The top of the guide block 109 is fixedly connected to the bottom of the transverse plate 102. The guide block 109 is provided to guide the movement of the transverse plate 102 and prevent the transverse plate 102 from deviating during the delivery of oxygen cylinder 3.

[0022] like Figure 2 and Figure 3 As shown, a set of guide rods 107 are fixedly connected to the inner wall of the fixed plate 101. The outer wall of the guide rods 107 is slidably connected to the inner wall of the guide block 109. The inner wall of the clamping block 113 is V-shaped, forming a V-groove. The guide rods 107 cooperate with the guide block 109 to restrict the movement direction of the transverse plate 102.

[0023] like Figure 3 As shown, an encoder 110 is fixedly installed on the inner wall of the fixed plate 101. The output end of the servo motor 105 is fixedly connected to one end of the threaded rod 108. The outer wall of the encoder 110 is fixedly connected to the other end of the threaded rod 108. The thread of the outer wall of the threaded rod 108 penetrates the inner wall of the slider 111. The encoder 110 can monitor the number of rotations of the threaded rod 108 in real time, and then calculate the moving distance of the transverse plate 102, and feed the data back to the control system to achieve precise control of the oxygen cylinder 3 delivery position.

[0024] like Figure 5As shown, the filling assembly 2 includes a connecting plate 201. A second electric push rod 205 is fixedly installed on the inner wall of the connecting plate 201. A lifting block 204 is fixedly connected to the shaft end of the second electric push rod 205. A filling head 203 is fixedly installed on the inner wall of the lifting block 204. A nut 202 is threadedly connected to the outer wall of the filling head 203. The second electric push rod 205 drives the lifting block 204 to move the filling head 203 up and down, automatically completing the docking of the filling head 203 with the oxygen cylinder 3.

[0025] like Figure 5 As shown, the top of the filling head 203 is fixedly connected to the air inlet pipe 206, and the top of the connecting plate 201 is fixedly connected to the support cylinder 207. The inner wall of the support cylinder 207 is slidably connected to the outer wall of the air inlet pipe 206. The support cylinder 207 plays a guiding and supporting role for the air inlet pipe 206, preventing the air inlet pipe 206 from shaking when the filling head 203 is raised and lowered.

[0026] The operating method and working principle of this device are as follows: First, place the oxygen cylinder 3 on the transverse plate 102. The PLC controller 103 activates two first electric push rods 112, which move the clamping block 113 and the rubber pad 114 to clamp the oxygen cylinder 3. Next, the servo motor 105 is activated, and its output drives the threaded rod 108 to rotate. Since the thread on the outer wall of the threaded rod 108 penetrates the inner wall of the slider 111, and the slider 111 is fixedly connected to the transverse plate 102, the rotation of the threaded rod 108 drives the slider 111 to slide along the inner wall of the fixed plate 101, thereby moving the transverse plate 102. Simultaneously, the guide block 109 slides along the guide rod 107, providing double guidance for the transverse plate 102 and preventing deviation during operation. During this process, the encoder 110 monitors the number of rotations of the threaded rod 108 in real time and accurately calculates the number of rotations of the transverse plate. The movement distance of 102 is measured and the data is fed back to the control system to ensure that the oxygen cylinder 3 is accurately delivered to the bottom of the filling component 2. When the oxygen cylinder 3 reaches the designated position, the second electric push rod 205 is activated, driving the lifting block 204 to descend, which in turn drives the filling head 203 on its inner wall to move down synchronously, so that the filling head 203 is accurately aligned with the branch pipe connector of the oxygen cylinder 3. Then, the user uses the nut 202 to firmly connect the filling head 203 to the branch pipe connector of the oxygen cylinder 3. The gas is delivered to the filling head 203 through the air inlet pipe 206 and then injected into the oxygen cylinder 3. After filling is completed, the nut 202 is loosened, and the second electric push rod 205 is controlled to drive the filling head 203 to rise and reset. Finally, the servo motor 105 is activated, driving the transverse plate 102 to transport the filled oxygen cylinder 3 to the far right, completing the entire automated filling process.

[0027] The PLC controller 103, servo motor 105, first electric push rod 112, second electric push rod 205, and filling head 203 used in this application are all common equipment on the market and are well known to those skilled in the art. In this application, the above equipment is used in a conventional manner without any improvement to its structure and function. As for their settings, installation, and electrical connection methods, those skilled in the art can debug and operate them according to the corresponding product instruction manuals, so they will not be described in detail here.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
