Description

Technical Field

[0002] In the industrial field, gas cylinders are widely used to store various industrial gases. In chemical production, they are also used to store compressed air, nitrogen and other gases. Gas cylinders need to work under different pressure environments. If the pressure resistance of the cylinder is insufficient, the cylinder is prone to deformation, concavity and damage. The internal pressure environment of the cylinder fluctuates, which may also cause gas leakage and cause safety accidents.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1 - Figure 8 As shown, this embodiment is a cylinder compression tester for processing gas storage cylinders, comprising a test base 1, sealing brackets 5 are symmetrically arranged at both ends of the test base 1, an arc-shaped sealing insert 501 is arranged on the top of the sealing bracket 5, and a cleaning mechanism 4 close to the sealing bracket 5 is arranged at one end of the test base 1;

[0031] A lifting roller rack 6 is arranged inside the test base 1, and a plurality of groups of balls 601 are arranged on the inner wall of the lifting roller rack 6. The cleaning mechanism 4 includes a return water pool 401 and a ring rack 402. The test machine is installed on the gas cylinder production and conveying production line. After the initial production of the gas cylinder is completed, the production and conveying production line transports them one by one to the test machine area.

[0032] A water storage cavity is recessed inside the test base 1, a water tank cover 101 is hinged on one side of the test base 1 and is sealed with the water storage cavity, an arc-shaped cylinder wall 102 is embedded on the top of the test base 1, a water collection tank 103 is recessed on the inner wall of the middle part of the arc-shaped cylinder wall 102, a water pump 104 is installed at the corner inside the water storage cavity, and a drainage valve and a water filling valve are arranged on the surface of the water collection tank 103;

[0033] The water pump 104 draws experimental water from the water storage chamber through a water pipe, and guides it into the arc-shaped cylinder wall 102 through a water injection valve until the air cylinder waiting for the test is completely submerged. The injection volume can be adjusted according to the test needs or the interior of the test machine can be filled. The continuously injected water pressure is used to squeeze the limited air cylinder externally, and a full-range covering pressurization process is implemented on the outside of the air cylinder.

[0034] There are multiple groups of long rectangular grooves on the surface of the lifting roller 6. The lifting roller 6 is composed of two groups of loose frames. Rotary cylinders 602 are hinged between the multiple groups of loose frames. Lifting cylinders 603 are set at the bottom of both ends of the rotary cylinder 602. The bottom of the lifting cylinder 603 is embedded in the test base 1. When the production conveying line transports the air cylinder waiting for test close to the test base 1, the lifting cylinder 603 drives the rotary cylinder 602 to slide up, prompting the lifting roller 6 to slide up synchronously until the height of the production conveying line connected to the two ends of the test base 1 is consistent. The production conveying line continues to transport, and with the cooperation of the auxiliary mechanical arms installed on the two ends of the test base 1, the air cylinder waiting for test is pushed onto the lifting roller 6.

[0035] An inflatable airbag wall located between multiple groups of balls 601 is provided on the top frame of the lifting roller 6. The inflatable airbag cushion is connected to the air pump pipeline through an air pipe. When the air cylinder waiting for test enters the lifting roller 6 at the initial stage, the multiple groups of balls 601 contact its outer wall and are pushed down in combination with the auxiliary mechanical arm until the air cylinder waiting for test stops in the middle of the lifting roller 6. When the auxiliary mechanical arm has not yet withdrawn, the air pump inflates the inflatable airbag cushion through the air pipe, causing the inflatable airbag cushion to swell and lift the air cylinder waiting for test to a limit position, so that the limit end cover 3 can perform end face contact limit treatment on it.

[0036] Embodiment 2: This embodiment is a cylinder compression testing machine for processing gas storage cylinders, including an observation top cover 2 arranged above the test base 1, limit end covers 3 symmetrically arranged at both ends of the observation top cover 2, a soft ring 304 is arranged on the inner wall of the limit end cover 3, and a plugging mechanism 7 is arranged on the bottom of the observation top cover 2, and the plugging mechanism 7 includes a beam frame 701 and a hole plugging sleeve 704.

[0037] The return water pool 401 is installed below the ring frame 402 and close to the sealing bracket 5. A heater and an air pump are arranged inside the return water pool 401. An inclined chamfered structure is arranged at one end of the ring frame 402 facing the test base 1, and a plurality of groups of jet inclined holes 403 are arranged on the surface of the inclined chamfered structure. The jet inclined holes 403 are connected to the air pump and the heater pipeline, and are used to guide the high-temperature hot steam to spray on the surface of the gas storage cylinder to remove the residual water stains on the surface of the gas storage cylinder.

[0038] The top area of ​​the observation cover 2 is a tempered transparent cover, and multiple groups of high-definition cameras and data acquisition sensors are embedded on the inner wall of the tempered transparent cover. Multiple groups of symmetrical lifting columns 201 are arranged on the outer walls on both sides of the observation cover 2. A sealing groove connected to the test base 1 is recessed on the bottom cross section of the observation cover 2.

[0039] When the air cylinder waiting to be tested is close to the testing machine area, the lifting cylinder column drives the observation top cover 2 to slide up through the fasteners, and the observation top cover 2 simultaneously drives the limit end covers 3 connected at both ends to slide up, so that the two ends and the top of the test base 1 remain unobstructed, which helps the production conveying line to transport the air cylinder waiting to be tested to the inside of the test base 1. When the air cylinder is in place inside the test base 1, the lifting cylinder further drives the observation top cover 2 and the limit end cover 3 to slide down, and the air cylinder waiting to be tested is sealed and limited inside the testing machine.

[0040] A sealing disk 302 which is sleeved with the test base 1 and the observation top cover 2 is arranged on the inner wall of the limit end cover 3, a sealing arc groove 303 which is sleeved with the sealing bracket 5 is arranged in a recessed manner at the bottom of the sealing disk 302, a propulsion cylinder 301 which is connected with the soft ring 304 is arranged on the outer wall of the limit end cover 3, and a plurality of main steam valve sleeves 305 are arranged on the inner wall of the soft ring 304.

[0041] During the period when the limit end cover 3 follows the observation top cover 2 to slide down synchronously, the sealing arc groove 303 is sleeved with the arc-shaped sealing insert 501, and the tops of both sides of the test base 1 are provided with convex strips sleeved with the sealing groove, so as to form a temporary sealing environment inside the test machine, and the lifting cylinder 603 further drives the air storage cylinder to be tested, which is limited by the inflated airbag cushion, to adjust the up and down height, and the propulsion cylinder 301 drives the soft ring 304 to move horizontally until the soft ring 304 is sleeved on both ends of the air storage cylinder to be tested;

[0042] The main steam valve sleeve 305 connects multiple sets of valves at both ends of the gas cylinder waiting for test to achieve end face clamping and sealing of the gas cylinder waiting for test. The main steam valve sleeve 305 is provided with a dedicated pipeline connected to the air pump for conveying gas into the gas cylinder waiting for test and detecting the internal air pressure bearing range of the gas cylinder.

[0043] The air pump is connected to the main steam valve sleeve 305 through a dedicated pipeline. A pressure gauge is set in the middle of the dedicated pipeline to detect the value of the air pressure continuously injected into the air cylinder, thereby constituting a continuous air pressure test inside the air cylinder, and according to whether bubbles are generated inside the submerged experimental water, it is used to detect the maximum air storage capacity and sealing effect of the air cylinder. A special valve connected to the external water source is set on the outer wall of the water tank cover 101. After the test is completed, the water pump 104 returns the experimental water inside the test machine to the water storage chamber through the drain valve, and guides the residual water stains inside the test machine through the water collecting tank 103 to accelerate the removal of water stains.

[0044] A plugging cylinder frame 702 is slidably sleeved on the inner wall of the beam frame 701, and a downward pressure cylinder 703 is set through the top center of the plugging cylinder frame 702. The bottom of the downward pressure cylinder 703 is sleeved with the hole plugging sleeve 704, and the plugging mechanism 7 slides down synchronously with the observation top cover 2 until the limit end cover 3 clamps the air storage cylinder waiting for test. The plugging cylinder frame 702 drives the hole plugging sleeve 704 to move along the beam frame 701 until the side valve port on the outer peripheral wall of the top of the air storage cylinder waiting for test is calibrated. The downward pressure cylinder 703 drives the hole plugging sleeve 704 to slide down until it is inserted into the side valve port, thereby blocking and sealing the side valve port.

[0045] During the pressure test of the gas cylinder, the test status of the gas cylinder inside the test machine can be directly observed by observing the tempered transparent cover on the top of the top cover 2. At the same time, multiple groups of high-definition cameras installed on the inner wall of the tempered transparent cover are used to collect whether there are leaked bubbles inside the experimental water. The data acquisition sensors include air pressure sensors and water pressure sensors, which are used to collect the values ​​of the continuous water pressure injected into the test machine and the residual air pressure values ​​on the top of the test machine, so as to facilitate the experimenters to accurately collect the test data of each group of gas cylinders, and compare them with the sample data retained in the cloud database, so as to obtain whether the test results of each group of gas cylinders are qualified.

[0046] After waiting for a single gas cylinder test to be completed, the experimental water inside the testing machine to be drained, and the gas inside the gas cylinder to be depressurized to a normal state, the limit end cover 3 and the plugging mechanism 7 are gradually separated from the gas cylinder, and the top cover 2 slides up and away from the gas cylinder at the same time. With the cooperation of the auxiliary robotic arm of the production conveying line, the tested gas cylinder on the lifting roller 6 is transferred. When it passes through the cleaning mechanism 4, the heater heat-treats the external gas extracted by the air pump, and then transports the high-temperature hot steam to the jet inclined hole 403 through a high-temperature resistant pipeline, so as to clean the hot gas on the surface of the tested gas cylinder to keep it dry and avoid affecting the subsequent gas cylinder processing steps.

[0047] Combining Example 1 and Example 2, it can be known that the present invention installs the testing machine on the production conveying line, and the gas cylinder is automatically transported to the testing area after the initial production. The various components work together, such as the lifting, lifting, and pushing cylinders 301 to automatically complete the sealing, clamping and positioning of the gas cylinder, saving manpower and improving efficiency.

[0048] During the test, a temporary sealed environment is created, the air pressure is accurately measured, and the air pump, water pump and other components cooperate to apply pressure to the inside and outside respectively, to fully test the performance of the air cylinder. After a single test, the water is automatically drained, the robot arm transports the gas, and the cylinder body is cleaned with hot air to ensure a smooth process.

[0049] The above contents are merely examples and explanations of the structure of the present invention. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner.
