Description

Technical Field

[0001] The utility model relates to the technical field of gas cylinders, in particular to a horizontal gas cylinder valve screwing mechanism. Background Art

[0002] Gas cylinders are devices used to store gaseous gases. Conventional gas cylinders can be divided according to the pressure they can withstand, materials, etc. Currently, most gas cylinders are composed of steel cylinders and valves installed in the steel cylinders.

[0003] Before filling the gas cylinder, the valve needs to be installed. After the gas in the gas cylinder is used up, the valve needs to be disassembled. Conventional valve disassembly and assembly mostly rely on manual operation with a wrench, but this method is laborious and time-consuming. At present, some gas cylinders also use corresponding equipment to disassemble and assemble the valve. Most of these equipment place the gas cylinder on the operating table and fix the gas cylinder. Then, the valve is disassembled and assembled by tools such as freely rotatable wrenches. Although it reduces the workload of workers, it is inconvenient for the placement of the gas cylinder on the operating table. Due to the steel structure of the gas cylinder itself, it is too heavy to be lifted by one person. In addition, the gas cylinder needs to be tilted and placed in advance, and it is easy to injure the worker if he is not careful. To this end, we propose a horizontal gas cylinder valve screwing mechanism to solve the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5The utility model provides a technical solution: a horizontal gas cylinder valve screwing mechanism, comprising a base 1, the base 1 is a horizontally placed strip block, and a cavity 2 is correspondingly opened on the top of the base 1, and a gas cylinder screwing device and a gas cylinder placing device are respectively arranged at the two ends of the top of the base 1, and the gas cylinder screwing device and the gas cylinder placing device are correspondingly arranged.

[0023] The gas cylinder placement device includes a first connecting rod 4, which is arranged parallel to the end of the base 1, and a first fixing plate 5 is vertically installed at the end of the first connecting rod 4, and the first fixing plate 5 is fixed on the end of the base 1. An L-shaped plate 3 is arranged above the base 1, and a plurality of second fixing plates 6 are vertically installed on the side of the L-shaped plate 3 close to the base 1, and the second fixing plates 6 are rotatably connected to the first connecting rod 4, and a clamping mechanism for fixing the gas cylinder is installed on the side of the L-shaped plate 3 away from the base 1. The L-shaped plate 3 can be rotated with the first connecting rod 4 as the axis. In actual use, the L-shaped plate 3 can be vertically erected at the end of the base 1 by rotating it, so that the gas cylinder can be placed on the L-shaped plate 3, wherein the inner side of the end of the L-shaped plate 3 is an inclined section, which helps to push the gas cylinder onto the L-shaped plate 3.

[0024] A first hydraulic cylinder 7 is provided inside the cavity 2 and is tilted. One end of the first hydraulic cylinder 7 is rotatably mounted on a second connecting rod 8. The end of the second connecting rod 8 is fixedly connected to the inner wall of the cavity 2. The other end of the first hydraulic cylinder 7 is rotatably mounted in a first U-shaped plate 9 through a rotating shaft. The first U-shaped plate 9 is fixed on the L-shaped plate 3. The operation of the first hydraulic cylinder 7 provides power for the rotation of the L-shaped plate 3, eliminating manual operation.

[0025] like Figure 1 As shown, the gas cylinder screwing device includes a sleeve 20, and a drive motor 23 is coaxially mounted on one end of the sleeve 20 away from the first connecting rod 4 through a connecting piece. The drive motor 23 is mounted on a support frame 29, and the support frame 29 is fixed to the base 1, as shown in FIG. Figure 4 As shown, a slot 21 is provided on the side surface of the other end of the sleeve 20 , and the front projection of the slot 21 is T-shaped. Clamping blocks 22 are installed on both sides of one end of the sleeve 20 close to the slot 21 , and the gap between the two clamping blocks 22 corresponds to the slot 21 .

[0026] When the horizontal gas cylinder valve screwing mechanism is actually used, the operator controls the first hydraulic cylinder 7 to drive the L-shaped plate 3 to rotate and vertically place it at the end of the base 1, and then the operator places the gas cylinder (such as Figure 5 The gas cylinder is moved from the position indicated by the arrow A in the middle to the L-shaped plate 3, wherein the gas cylinder comprises a cylindrical steel cylinder body, a through hole is opened on the top of the steel cylinder body, and a valve is threadedly installed on the through hole;

[0027] like Figure 5As shown, after the gas cylinder of the L-shaped plate 3 is fixed by the clamping mechanism, the first hydraulic cylinder 7 drives the L-shaped plate 3 to tilt on the base 1, so that the gas cylinder is placed horizontally, and then the sleeve 20 is rotated and adjusted through the connecting piece so that the handle of the valve (such as Figure 5 The position indicated by the arrow C in the middle) can pass through the slot 21 and be placed in the sleeve 20. At this time, the clamping block 22 will be relatively close to the hexagonal prism of the valve (such as Figure 5 On the two side planes of the position indicated by the middle arrow B), when the sleeve 20 rotates, the two clamping blocks 22 play a relative limiting role on the hexagonal prism of the valve, thereby driving the valve to rotate and realizing the screwing and disassembly operation of the valve.

The sleeve 20 can ensure stable rotation and can also be deflected with the transmission universal joint 25 as the axis, so that the sleeve 20 can be sleeved on the valve of the gas cylinder; and due to the action of the spline shaft 27 and the spline sleeve 28, the sleeve 20 can be adjusted horizontally, which is convenient for the use of the sleeve 20.

[0029] Furthermore, in order to prevent the sleeve 20 from being dislocated and offset due to the action of the transmission universal joint 25 when rotating, thereby affecting the rotation of the valve by the clamping block 22, support wheels 31 are provided on both sides below the transmission shaft 26. The support wheels 31 are closely attached to the outer wall of the transmission shaft 26, and the support wheels 31 are installed on a U-shaped frame 32, which is fixedly connected to the base 1. The position of the sleeve 20 is limited to prevent the sleeve 20 from being dislocated.

[0030] Furthermore, if Figure 1 As shown, a cross beam 19 is provided below one end of the L-shaped plate 3 away from the first connecting rod 4, the end of the cross beam 19 is fixed to the side edge of the base 1, and a buffer pad is installed on the top of the cross beam 19. When the gas cylinder is placed horizontally, the L-shaped plate 3 is supported and the deflection process of the L-shaped plate 3 toward the base 1 is also buffered.

[0031] Furthermore, if Figure 1As shown, two limit blocks 10 are installed on the inner side of the L-shaped plate 3, and the limit blocks 10 are installed on the L-shaped plate 3 along the length direction of the base 1, and the top surfaces of the two limit blocks 10 are coaxially arranged arc-shaped concave surfaces.
