Description

Technical Field

[0001] The utility model relates to the technical field of gas filling, in particular to a continuous gas cylinder filling device. Background Technique

[0002] The gas cylinder filling needs to go through steps such as connecting the filling head - opening the cylinder valve - opening the gas circuit valve - closing the cylinder valve - closing the gas circuit valve - disconnecting the filling head in sequence. If the filling is carried out in a way that only one cylinder is filled at a time, the filling efficiency is too low. Therefore, at present, the batch filling method is adopted for gas cylinder filling. First, multiple gas cylinders are arranged in a matrix within a frame, and then the frame is lifted and transported to the filling area. There are multiple liftable filling heads in the filling area. After controlling the multiple filling heads to descend and connect to all the multiple gas cylinders at one time, then filling is carried out at one time. Finally, the filling heads are disconnected and lifted together to prevent the gas cylinders from getting stuck with the filling heads. Then, after the frame is lifted away, another batch of gas cylinders is lifted and transported, and so on. In this way, the time for opening and closing the gas circuit valve can be combined together, thereby improving the filling efficiency.

[0003] The inventor found during the work process that one worker is responsible for one filling area. This worker connects the gas cylinders in the frame one by one in sequence, disconnects them one by one after filling is completed, raises all the filling heads, removes the old frame, moves in the new frame and then repeats the operation. If another worker can be arranged to connect the removed filling heads to the gas cylinders of the new frame when the worker disconnects the filling heads of the gas cylinders, when all the gas cylinders of the old frame are disconnected, all the gas cylinders of the new frame are also completely connected, then the gas cylinders in the new frame can be filled before the old frame is removed, realizing continuous filling and effectively improving the efficiency. However, the filling heads of the existing filling devices are all fixed on the same lifting frame and move up and down together. When implementing the above-mentioned scheme, it is necessary to frequently control the lifting frame, and the following problems cannot be conveniently solved. One is that when moving the filling heads above the old frame to above the new frame, it is necessary to ensure that the filling pipeline is long enough, and when the filling heads are connected to the new frame, the filling pipeline cannot interfere with the gas cylinders of the old frame, otherwise it will prevent the removal of the old frame. The second is that in the later stage of filling the new frame, the filling pipeline of the filling head should be vertically downward, so that when the filling head is removed after filling is completed, the filling head will not be pulled and swung by the filling pipeline and hit or entangle with the gas cylinders.

[0004] In view of this, a continuous gas cylinder filling device is designed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a continuous gas cylinder filling device to solve the problems described in the background technique.

[0006] The technical solution of the utility model is realized as follows:

[0007] A continuous gas cylinder filling device includes a rectangular bottom frame and a roller conveyor belt arranged inside the bottom frame. On the left and right sides at the upper end of the bottom frame, there are also multiple vertical rods and horizontal rods respectively. The bottom of the vertical rods is fixedly arranged on the bottom frame, and the horizontal rods are horizontally arranged and fixedly arranged on the side of the vertical rods facing the center of the bottom frame. At the center above the bottom frame, there is also an inflation mounting frame, which is fixedly arranged on the top of the vertical rods. An upper connecting rod and a lower connecting rod are fixedly arranged on the inflation mounting frame. The upper connecting rod is arranged above the lower connecting rod. Horizontally and fixedly arranged on the lower connecting rod are multiple fixed shafts arranged at intervals. Multiple fixed pulleys arranged at intervals are rotatably mounted on the fixed shafts. A pipe groove is circumferentially formed on the outer wall of the fixed pulley. Horizontally and fixedly arranged on the lower connecting rod are also multiple connecting plates arranged at intervals. The number of connecting plates is the same as that of the fixed shafts. At the bottom of the connecting plates, multiple sliding rails arranged at intervals are also fixedly arranged. The number of sliding rails is the same as that of the fixed pulleys. On the sliding rails, movable pulleys are also slidably and rotatably connected. A pipe groove is also circumferentially formed on the outer wall of the movable pulley. Horizontally and fixedly arranged on the upper connecting rod are multiple mounting rods arranged at intervals. The number of mounting rods is the same as that of the fixed shafts. Multiple limiting sleeves are also fixedly arranged on the mounting rods. The number of limiting sleeves is the same as that of the fixed pulleys. The multiple limiting sleeves, movable pulleys, and fixed pulleys are matched one by one to form multiple lifting control mechanisms. Each lifting control mechanism is also equipped with a flexible air pipe. After the flexible air pipe is fixedly passed through the limiting sleeve from top to bottom, the flexible air pipe extends downward to the bottom of the movable pulley and then extends upward around the movable pulley to the top of the fixed pulley. The flexible air pipe then extends downward around the fixed pulley and is provided with an inflation head. The flexible air pipe is respectively slidably embedded in the pipe grooves of the fixed pulley and the movable pulley. When only affected by gravity, the movable pulley in the lifting control mechanism is at the bottom of the sliding rail.

[0008] When using the above scheme, the frame filled with gas cylinders is hoisted to the roller conveyor belt at one end above the bottom frame. The guardrails formed by the horizontal rods on the left and right sides can effectively limit the sliding route of the frame. The frame is pushed to directly below the inflation mounting frame. By setting the positions of the lifting control mechanisms, the multiple inflation heads are exactly above each corresponding gas cylinder in the natural hanging state. The staff pulls the inflation head downward. The inflation head pulls the flexible air pipe. The flexible air pipe passes through the pulley block and pulls the movable pulley to slide upward along the sliding rail, thereby releasing the length of the flexible air pipe and moving the inflation head downward to the inflation port of the gas cylinder. When the staff connects all the inflation heads to the gas cylinders one by one, the gas cylinders start to be filled. During the filling period, a new frame is hoisted to the roller conveyor belt at one end of the bottom frame for standby.

[0009] When the gas cylinders in the old frame at the center of the bottom frame are full, a staff member is responsible for removing the inflation head. The removed inflation head rises and resets under the sliding action of the movable pulley of the corresponding lifting control mechanism, so that the removed inflation head will not fall and hit the gas cylinder or be entangled with the gas cylinder. At the same time, another staff member is responsible for pulling the removed inflation head to the new frame on the outside and connecting it to the gas cylinder in the new frame. Since each inflation head is independently matched with a lifting control mechanism, when pulling a single inflation head, the flexible hose of the inflation head is independently controlled and will not interfere with other inflation heads, and there is no need to uniformly control the lifting of the inflation heads as in traditional devices. When all the inflation heads of the old frame are removed, even if the inflation heads and flexible hoses have not had time to be connected to the gas cylinders in the new frame, they will not interfere with the gas cylinders in the old frame. At this time, the old frame can be moved out of the center of the bottom frame and lifted away by a hoisting device, while the connection work of the gas cylinders in the new frame is also carried out synchronously, improving the connection efficiency.

[0010] When all the gas cylinders in the new frame are connected, the inflation of the gas cylinders in the new frame can start, and during the inflation process, the new frame is moved to the center of the bottom frame. During the movement, the flexible hose will automatically move up and reset, avoiding the flexible hose being too long and entangled with the gas cylinder, and there is no need for the staff to manually control the lifting of the inflation head. At the same time, a new frame is hoisted onto the bottom frame, and this process is repeated continuously to achieve continuous inflation of the gas cylinders.

[0011] Through the independent lifting control mechanism, when the inflation head above the old frame moves above the new frame, it can automatically release the length of the charging pipeline under the pulling of the staff to meet the requirements. At the same time, the movable pulley moves downward under gravity and pulls the flexible hose, so that the flexible hose is taut when the inflation head is connected to the new frame, and will not interfere with the gas cylinders in the old frame and does not prevent the removal of the old frame. The independent lifting control mechanism also makes the inflation head and the flexible hose perpendicular downward and taut in the later stage of inflation of the new frame. When the inflation head is removed after the inflation is completed, the inflation head automatically moves up and resets, and the inflation head is far away from the gas cylinder, avoiding hitting or entangling with the gas cylinder and facilitating the rapid removal of the old frame.

[0012] A further technical solution is that the inflation mounting frame includes four vertical rods, two vertical rods are fixed on the left vertical column, and the other two vertical rods are fixed on the right vertical column, so that the four vertical rods form a rectangular enclosure. The upper connecting rod includes two, one upper connecting rod is connected between the two left vertical rods, and the other upper connecting rod is connected between the two right vertical rods. The lower connecting rod includes two, one lower connecting rod is connected between the two left vertical rods, and the other lower connecting rod is connected between the two right vertical rods.

[0013] A further technical solution is that both ends of the fixed shaft are respectively fixedly connected to the two lower connecting rods, both ends of the connecting plate are respectively fixedly connected to the two lower connecting rods, and both ends of the mounting rod are respectively fixedly connected to the two upper connecting rods.

[0014] A further technical solution is that the central rotating sleeve of the fixed pulley is sleeved on the fixed shaft.

[0015] A further technical solution is that the slide rail consists of two opposed U-shaped frames. The middle part of the U-shaped frame is a straight and long chute. The top of the U-shaped frame is fixedly arranged on the connecting plate. Rotating shafts are respectively fixedly arranged at the centers on both sides of the movable pulley. The rotating shafts are slidably and rotatably arranged in the straight and long chute. The movable pulley is slidably and rotatably installed between the two opposed U-shaped frames through the rotating shafts at both times.

[0016] A further technical solution is that the roller conveyor belt includes a plurality of rollers arranged at equal intervals. Both ends of the rollers are rotatably installed on the left and right frame walls of the bottom frame.

[0017] The beneficial effects of the present utility model are as follows:

[0018] 1. High-efficiency continuous operation: Through the design of an independent lifting control mechanism and a roller conveyor belt, continuous filling operation of gas cylinders is realized, improving work efficiency.

[0019] 2. Convenient operation: When the inflation head is removed, it can automatically move up and reset, avoiding impact or entanglement with the gas cylinder, and facilitating the rapid removal of the gas cylinder in the old frame. At the same time, each inflation head is independently matched with a lifting control mechanism, so that when the inflation head above the old frame moves to above the new frame, it can automatically release the length of the inflation pipeline under the pulling of the staff to meet the requirements, and will not interfere with the gas cylinders in the old frame, realizing the individual control of the inflation head, simplifying the operation process, and shortening the operation waiting time.
