Description

Technical Field

[0001] The present invention relates to the technical field of pipe fitting testing, and in particular to a water pressure testing device with a safety protection function. Background Art

[0002] In the production and quality inspection of ductile iron pipe fittings, hydrostatic testing is a crucial process. Its purpose is to accurately detect whether there are leaks in the pipe fittings, ensure that product quality meets standards, and guarantee safety and reliability in actual applications. Existing hydrostatic testing equipment has exposed many problems during actual operation. Traditional pipe transportation methods are inefficient and rely heavily on manual operation. Manual handling can easily cause damage to the pipe fittings, affecting the quality of the pipe fittings. During transportation, the collection of basic pipe fitting parameters lacks systematic and automated methods, making it difficult to obtain comprehensive and accurate pipe fitting data during the transportation stage, which is not conducive to the efficient implementation of subsequent testing. During the hydrostatic testing process, safety hazards are prominent and effective protective measures are lacking. Once a pipe fitting has a leak, water leakage or even fragments flying during the pressure test process is likely to occur, posing a serious threat to the personal safety of the operator. After the test, the qualified and unqualified pipe fittings cannot be quickly and accurately sorted and transported according to the test results. Manual sorting is often required, which not only increases labor intensity but also easily leads to classification errors, affecting production efficiency and product quality control.

[0003] In summary, the existing water pressure testing equipment for ductile iron pipe fittings has obvious defects in pipe transportation, test safety and accuracy, and classification and processing of pipe fittings after testing. There is an urgent need for a new water pressure testing device with safety protection function to improve the efficiency, safety and reliability of pipe fitting inspection and reduce labor costs and safety risks in the production process.

[0017] Beneficial effects of the present invention:

[0018] (1) Through the work of the transportation mechanism, the ductile iron pipe fittings to be tested can be continuously transported to the testing institution, reducing labor costs and improving transportation efficiency. During the transportation process, the industrial camera in the image data acquisition component can collect and record basic parameter data such as the height, diameter and surface smoothness of the pipe fittings, thereby providing basic information for subsequent tests;

[0019] (2) The conveying trough of the test mechanism is firmly supported by the legs and vertical rods. The notch at the front end is convenient for pouring the pipes. The support bars and buffer pads can effectively reduce the impact of the pipes on themselves and the conveying trough when they fall, protecting the pipes and equipment. The block can prevent the pipes from rolling directly from the other side of the conveying trough, ensuring the stability of the pipe transportation process. The clamping plate of the water pressure test component can clamp the pipes in the center. The sealing gasket enhances the sealing while protecting the pipe ends. The two inlet and outlet valve pipes are connected to different equipment. Water is injected and pressurized according to a specific process. The leakage point is accurately determined based on the pressure curve and the water seepage on the outer surface of the pipe. The test efficiency is high and the water pressure is stable. In addition, the protective shell encloses the pipes during the water pressure test to prevent water leakage and splashing of debris generated by leakage points in the pipes during pressure testing, effectively avoiding safety hazards.

[0020] (3) The transportation and classification mechanism can classify and transport the pipes according to the test results. The image data acquisition component continuously monitors the test status. If the pipe is qualified, the pipe is gradually transported to the other side of the pallet through the coordinated operation of the intermittent transportation and management components and sent out by the conveyor belt. If the pipe is unqualified, the electric telescopic rod pushes the push plate to push the waste pipe to the wedge-shaped unloading plate of the classification component, and it falls onto the conveyor belt through the discharge port and is transported out, which is convenient for the subsequent classification and processing of qualified and unqualified pipes.

[0021] (4) Through the cooperation of the above-mentioned mechanisms, the transportation mechanism efficiently transports pipe fittings, and the pipe conveying components are pushed accurately according to the test progress. At the same time, the image data acquisition component records the basic parameters of the pipe fittings, which not only improves efficiency but also reduces labor costs. The support bars and buffer pads of the conveying trough in the test mechanism protect the pipe fittings and themselves, and the blocks ensure the stable transportation of the pipe fittings. The water pressure test components accurately center and clamp the pipe fittings, and inject water and pressurize according to the process to detect leaks. The protective shell effectively prevents water leakage and debris splashing, ensuring the safety of the test. The transportation and classification mechanism uses the image data acquisition component for monitoring. According to the test results, it can accurately classify and transport qualified and unqualified pipe fittings through intermittent transportation and classification components for subsequent processing, thus achieving efficient and safe water pressure testing and classification of ductile iron pipe fittings.

By observing whether there is water seepage on the outer surface of the pipe fitting, it can be determined whether there is a leak in the pipe fitting. After the water pressure test of the pipe fitting is completed, the closed inlet and outlet water valve pipes 20913 are reopened. Since the water pressure in the pipe is relatively high, the water in the pipe can be quickly re-input into the water tank through the reopened inlet and outlet water valve pipes 20913, thereby completing a water pressure test on the pipe fitting. The test efficiency is high and the water pressure is stable.

[0046] In summary, when the ductile iron pipe fittings are subjected to a water pressure test, the pipe fittings to be tested can be transported to the inner side of the conveying trough 201 in the testing mechanism 2 through the operation of the transport mechanism 1. When the pipe fittings fall into the conveying trough 201, the receiving end of the pipe fittings first contacts the buffer pad 205, thereby maximally reducing the impact force generated when the pipe fittings fall. After the pipe fittings have completely fallen into the conveying trough 201, the support bar 204 can also assist the buffer pad 205 in protecting the other end of the pipe fittings and prop up the other end of the pipe fittings, so that the pipe fittings can be more easily removed from the buffer pad 205. The top of the pipe rolls down, and when the pipe rolls down from the buffer pad 205, it can smoothly transition to the other side of the inside of the conveying trough 201. When the pipe rolls from one side of the conveying trough 201 to the other side, the stopper 207 can block the pipe that rolls down to its side to prevent the pipe from directly slipping off the top of the conveying trough 201. At the same time, the servo motor 2092 in the water pressure test component 209 starts to work, and the servo motor 2092 provides power to the gear 2097, which can make the gear 2097 rotate in the positive direction or reverse direction inside the support shell 2091, thereby transmitting the power through the gear 2097. The racks 2098 fixed on the inner sides of the two L-shaped slides 2096 are driven to slide in opposite directions, thereby driving the two L-shaped slides 2096 to move simultaneously through the racks 2098, and driving the clamping plate 20910 to clamp the pipe fittings in the center through the support rod 2099. After clamping the pipe fittings, the two inlet and outlet valve pipes 20913 work together to perform a water pressure test on the pipe fittings to detect whether there are any leaks in the pipe fittings. After the test is completed, the output end of the electric telescopic rod 2094 will push the support shell 2091 to slide to its side, thereby driving the clamping plate 2091 through the support shell 2091. 0 and the pipe fittings clamped on the inner side thereof move toward the side of the transport and classification mechanism 3. When the pipe fitting moves to the other side of the stopper 207, the servo motor 2092 controls the gear 2097 to rotate in the opposite direction, thereby releasing the clamping plate 20910, canceling the clamping of the pipe fitting, and rolling it through the top of the outermost side of the conveying trough 201 into the transport and classification mechanism 3. After the pipe fitting is transported to the inside of the transport and classification mechanism 3, the electric telescopic rod 2094 drives the support shell 2091 to return to its original position, and waits for the next pipe fitting to roll to its inner side, and then the new pipe fitting can be subjected to the water pressure test again.

At the same time, when the reciprocating groove seat 3078 drives the transport block 3079 to reciprocate, the pipe fittings originally clamped in the semicircular slot opened at the top of the card plate 3071 can be transported to the inside of the semicircular slot on the other side. , thereby achieving the purpose of intermittent transportation of pipe fittings, making it convenient to push waste pipes out from the top of the pallet 3071. The right side of the inner bottom end of the pallet 3071 is rotatably connected to a conveyor belt 30710. The conveyor belt 30710 is used to transport pipe fittings that have rolled to its top and are determined to be qualified after the water pressure test.

[0054] Example 4

[0055] See also Figures 1-13 As shown, this embodiment is obtained by combining Example 1, Example 2 and Example 3. The water pressure testing device of the present invention is intended to efficiently and safely perform water pressure testing on ductile iron pipe fittings, and to realize the transportation, testing and classification of the pipe fittings.

[0056] The conveyor mechanism 1 is used to transport pipes. Because the conveyor housing 101 is tilted, with one end near the conveyor trough 201 in the testing mechanism 2 higher than the other, the movement of the rollers 110 pushes the ductile iron pipes placed on the conveyor housing 101. Simultaneously, the tilted structure forces the pipes to rotate at the top of the conveyor housing 101. The stop bar 104 blocks the pipes to prevent them from sliding. During the movement and rotation of the pipes, the image data acquisition assembly 4 at the top of the reinforcement frame 105 captures image data of the pipes, enabling both transport and data collection.

[0057] The testing mechanism 2 receives the pipes from the transport mechanism 1. The conveying trough 201 is firmly supported by the legs 202 and the vertical rods 203, and the notch at the front end facilitates the pouring of pipes. The support bars 204 and the buffer pads 205 protect the bottom and top of the pipes respectively, reducing the impact force when the pipes fall. When the pipes roll to the other side of the conveying trough 201, the block 207 prevents them from sliding directly. The water pressure test component 209 slides on the slide rail 208, and the servo motor 2092 drives the gear 2097 to rotate, thereby driving the rack 2098 and the L-shaped slide to move, so that the support rod 2099 drives the clamping plate 20910 to center and clamp the pipe. The sealing gasket 20912 enhances the sealing between the pipe and the clamping plate 20910, while protecting the end of the pipe. Two water inlet and outlet valve pipes 20913 are connected to the water tank, centrifugal pump, and plunger-type high-pressure water pump, respectively. Water is injected into the pipes according to a specific process to increase pressure. Leakage is determined based on the pressure curve and the presence of water seepage on the pipe's outer surface. After testing, the electric telescopic rod 2094 pushes the support shell 2091, transferring the pipe to the transport and sorting mechanism 3. The support shell 2091 then resets to await the next pipe.

[0058] The transport and sorting mechanism 3 is responsible for the subsequent processing of tested pipes. The protective shell 303 encloses the pipes during the hydraulic test to prevent water leakage and splashing debris. The image data acquisition component 4 continuously monitors the test status of the pipes. If the pipes pass the test, the transmission motor 3074 in the intermittent transport component 307 drives the driving wheel 3072, which drives the driven wheel 3075 via the belt 3076. The connecting rod 3077 drives the reciprocating groove seat 3078 and the transport block 3079, gradually transporting the pipes to the other side of the pallet 3071 and then being transported out by the conveyor belt 30710. If the pipes fail the test, the electric telescopic rod 304 pushes the push plate 305, pushing the waste pipes onto the wedge-shaped discharge plate 3064 of the sorting component 306. The waste pipes fall through the discharge port onto the conveyor belt 3062 and are then transported out by the conveyor belt 3062. The trough plate 3061 of the classification component 306 supports the conveyor belt 3062, and the transmission motor 3063 provides power for it to realize the transportation of waste pipes.

[0059] In summary, the water pressure testing device, through the close cooperation of the transportation mechanism 1, the testing mechanism 2 and the transportation management and classification mechanism 3, with the assistance of the image data acquisition component 4, efficiently and safely completes the water pressure testing and classification of ductile iron pipe fittings, thereby improving the efficiency and safety of pipe fitting inspection and reducing labor costs.
