[0026] The present invention will be further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are only illustrative and not restrictive, and the protection scope of the present invention cannot be limited thereto.

[0027] A gas seal detection device for steel cylinder production, see Figure 1-4 , the invention point is:

[0028] It includes a water pool 2 filled with water. The water pool is arranged on one side of a chain conveyor line 100, and the chain conveyor line is connected between the head butt welding equipment and the bottle body tempering treatment equipment.

[0029] The invention comprises a cylinder input mechanism 1 for temporarily storing and aligning a plurality of cylinders, and a cylinder clamping and immersing mechanism for tilting the cylinders by 90 degrees. One end of the cylinder clamping and immersing mechanism is the cylinder input end, and the other end is the cylinder output end. The cylinder input mechanism is arranged on the chain conveyor line and is located at the rear end of the cylinder input end, and is used to convey a plurality of closely aligned cylinders to the cylinder clamping and immersing mechanism together.

[0030] The steel cylinder clamping and immersion mechanism comprises a steel cylinder clamping bracket 4 that can clamp multiple steel cylinders at the same time and a bracket 90° tilting driving mechanism 3. The steel cylinder clamping bracket comprises a bracket body 4.1, which is a frame structure formed by connecting a left frame and a right frame at the top. The lower part of the left frame is inserted into the pool, and a rotating shaft 4.7 is arranged at the lower end of the left frame to form the rotation center of the steel cylinder clamping bracket. The rotating shaft is supported on the front and rear side walls of the pool, and one end of the rotating shaft extends from the corresponding side wall of the pool and is connected to the bracket 90° tilting driving mechanism. The mating part where the rotating shaft extends from the pool can be installed with bearings and common mechanical sealing structures to avoid water leakage. Fixed clamping columns 4.2 are evenly distributed and vertically fixed on the inner side of the upper part of the left frame along the conveying direction of the chain conveyor line. Specifically, corresponding to each fixed clamping column, an upper horizontal plate and a lower horizontal plate are fixed on the inner part of the left frame, and column holes aligned along the vertical direction are arranged on the two horizontal plates, and the fixed clamping columns are installed and fixed in the column holes. Dynamic clamping columns 4.3 are arranged on the inner side of the right frame at positions relative to the fixed clamping columns. The dynamic clamping columns are vertically fixed on the column frame 4.4. The column frame is movably supported on the supporting beam of the right frame through horizontal guide columns 4.5 along the left and right directions. A dynamic clamping column driving cylinder 4.6 is installed on the supporting beam. The dynamic clamping column driving cylinder is connected to the outer end of the column frame.

[0031] When the 90° tilting drive mechanism of the bracket is in the first working position, the cylinder clamping bracket is in a vertical position, and the left frame and the right frame of the bracket body are respectively located on both sides of the chain conveyor line; when the 90° tilting drive structure of the bracket is in the second working position, the cylinder clamping bracket is flipped 90° into the water pool to a horizontal position and immersed in the water pool, so that multiple cylinders clamped at the same time can be placed into the water pool.

[0032] In the above structure, the 90° tilting drive mechanism of the bracket is preferably: including: a tilting drive cylinder 3.2, which is installed outside the pool at the end of the extended rotating shaft, the cylinder barrel end of the tilting drive cylinder is hinged to the support 3.1 fixed on the ground, the cylinder rod end of the tilting drive cylinder is connected to the tilting drive arm 3.3, the outer end of the tilting drive arm is relatively rotatably connected to one end of the tilting drive swing arm 3.4, and the other end of the tilting drive swing arm is fixedly connected to the extended end of the rotating shaft. When the tilting drive mechanism is adopted, when the cylinder rod of the tilting drive cylinder is extended, the rotating shaft rotates in the clockwise direction, so that the cylinder clamping and immersing mechanism is rotated to the vertical position. At this time, the cylinder input mechanism can be opened, and multiple aligned cylinders can be synchronously conveyed to between the dynamic clamping column and the fixed clamping column of the cylinder clamping and immersing mechanism through the chain conveyor line. After all the multiple cylinders are moved into the cylinder clamping and immersing mechanism, the cylinder rod of the dynamic clamping column driving cylinder is extended, and the multiple cylinders are clamped at the same time through the dynamic clamping column and the fixed clamping column, and then the cylinder rod of the tilting drive cylinder is retracted, driving the rotating shaft to rotate 90° counterclockwise, so that the cylinders are tilted into the water pool to realize air tightness detection.

[0033] In the above structure, further: the left side frame is a long side frame, and the right side frame is a short side frame. When the cylinder clamping bracket is in a vertical position, the lower end of the right side frame is supported on an auxiliary bracket platform arranged outside the chain conveyor line. The stability of the cylinder clamping bracket in the vertical position is ensured. In addition, in order to ensure the stability of the cylinder clamping bracket when it is tipped to a horizontal position, an inwardly protruding rib can be welded on the inner wall of the side of the pool away from the chain conveyor line near the upper end, so that the cylinder clamping bracket is supported on the rib after tipping.

[0034] In the above structure, further: rubber sleeves are mounted on the fixed clamping column and the dynamic clamping column near the upper and lower ends, so that the rubber sleeves can contact the surface of the cylinder to avoid clamping damage to the surface of the cylinder.

[0035] In the above structure, further: the cylinder input mechanism is a left-right symmetrical mechanism, which is respectively arranged on both sides of the conveyor chain. Each side mechanism includes a temporary storage drive cylinder 1.2, a cylinder bracket 1.1, a column 1.4 and a temporary storage drive swing 1.3. The cylinder bracket and the column are vertically fixed to the upper end of the stand outside the conveyor chain. The temporary storage drive swing consists of a sleeve part 1.3.2, a drive arm part 1.3.1 and a stop arm part 1.3.3. The drive arm part and the stop arm part are vertically welded to the outside of the sleeve part at an angle. The sleeve part is rotatably sleeved on the column. The cylinder barrel end of the temporary storage drive cylinder is hinged to the cylinder bracket, and the cylinder rod end is hinged to the outer end of the drive arm part. The cylinder rods of the temporary storage drive cylinders on both sides are in the extended position, and the stop arm parts on both sides swing inward to the position of blocking the cylinders. The cylinder rods of the temporary storage drive cylinders on both sides are in the retracted position, and the stop arm parts on both sides swing outward to the position of breaking contact with the cylinders.

[0036] In the above structure, further: a rubber sleeve in contact with the steel cylinder is sleeved on the barrier arm portion, so that the rubber sleeve is in contact with the steel cylinder, thereby preventing the surface of the steel cylinder from being hard-damaged.

[0037] The working process of the gas seal detection device for cylinder production is as follows:

[0038] The steel cylinders 200 in process, which are welded and formed by the head butt-welding equipment, are transported to the tempering treatment equipment through the chain conveyor line. The steel cylinders are separated by a large distance during the transportation process. When the steel cylinders are transported to the position of the steel cylinder input mechanism of the gas-tight detection device, they are blocked by the blocking arms on both sides, and the steel cylinders are suspended from being transported forward. In this way, with the subsequent steel cylinders transported, multiple steel cylinders are aligned with each other front and back. When the number of suspended steel cylinders reaches the set number (which can be detected by a sensor or counted by a counter 5, the sensor or counter is installed on one side of the conveyor chain of the chain conveyor line, and the position of the sensor or counter is preferably installed close to the set alignment steel cylinder. The cylinder is at the rear end of the last cylinder in the cylinder), and the temporary storage drive cylinders on both sides are actuated to swing the blocking arms on both sides outward, thereby releasing the obstruction to the cylinder. Driven by the conveyor chain, multiple aligned cylinders are synchronously transported back and forth to the left and right frames of the cylinder clamping and immersion mechanism; when multiple cylinders are delivered to the right position, the dynamic clamping column drive cylinder and the overturning drive cylinder are successively actuated to make multiple cylinders clamped by the column, and then overturned as a whole into the water pool, so as to realize the one-time gas sealing detection of multiple cylinders. During the detection process, according to the specific immersion situation, the dynamic clamping column can be loosened, the cylinder can be turned over, and the lower part of the cylinder can be turned over to the upper part to facilitate marking the leaking part. When the detection is completed, all cylinders are in the clamping state, turn the cylinder clamping bracket (driving the cylinder) to the vertical position, and then loosen the dynamic clamping column. At this time, driven by the conveyor chain, multiple cylinders continue to be transported forward to the next process equipment.

[0039] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will appreciate that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
