Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning, in particular to a ball collecting cylinder buffer device for a natural gas pipeline. Background Art

[0002] The ball collecting cylinder is an important component of the pipeline cleaning and line sweeping equipment. It is installed at both ends of the pipeline to launch and receive the pipe cleaning device. It is mainly composed of quick-opening blind plates, cylinders, reducers, saddle brackets and other parts. In the operation of natural gas pipelines, regular pipeline cleaning and internal inspection operations are the guarantee of safe pipeline operation.

[0003] After investigation: the patent specification with announcement number CN202320795017.5 discloses a pipeline ball collector, including: a ball collector body, including a ball collecting cylinder and a ball taking cylinder connected to and in communication with the ball collecting cylinder at an angle; a ball blocking pipe joint, which is detachably mounted on the bottom of the ball collecting cylinder, and a blocking plate is provided between the ball blocking pipe joint and the ball collecting cylinder, and a buffer and a first through hole for discharging liquid are provided on the blocking plate. The pipeline ball collector provided by the utility model blocks balls at the bottom of the ball collecting cylinder by a blocking plate, and a buffer is provided on the blocking plate for buffering, thereby reducing direct impact on the blocking plate and improving service life.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned pipeline ball collector has the following problems: a buffer plate made of rubber material is arranged on the blocking plate. When the cleaning rubber ball falls into the ball collector, the energy of the impact of the cleaning rubber ball can be absorbed by the buffer plate made of rubber material. The buffer plate made of rubber material mainly relies on deformation to absorb the impact energy. However, the deformation amount of the buffer plate is limited and cannot fully absorb the impact energy of the cleaning rubber ball. Some of the energy will still directly act on the ball collector and the cleaning rubber ball, which may easily cause damage to the ball collector and the cleaning rubber ball. In view of this, a natural gas pipeline ball collecting cylinder buffer device is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a natural gas pipeline ball collecting cylinder buffer device.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a natural gas pipeline ball collecting cylinder buffer device, comprising a natural gas pipeline and a ball collecting cylinder, the ball collecting cylinder is fixedly installed at the bottom end of the natural gas pipeline, and a transmission slide is clamped inside the ball collecting cylinder, a cleaning ball transmission seat is arranged on the top of the transmission slide, and a clamping concave surface is provided on the top of the cleaning ball transmission seat, a plurality of transmission arms are arranged on the peripheral side of the transmission slide, and the transmission arms extend to the outside of the ball collecting cylinder, a plurality of hydraulic damping rods cooperating with the transmission arms are fixedly installed on the peripheral side of the ball collecting cylinder, and a guide groove cooperating with the transmission arm is provided on the peripheral side of the ball collecting cylinder.

[0007] As a further description of the above technical solution: the cleaning ball transmission seat and the middle part of the transmission slide are provided with mutually matching through holes, and the top of the clamping concave surface and the inner wall of the ball receiving tube are smoothly transitioned at the connection, ensuring that the cleaning rubber ball can stably fall into the clamping concave surface along the natural gas pipeline, so that the impact force acts completely on the transmission slide.

[0008] As a further description of the above technical solution: the shape of the engaging concave surface is hemispherical, and the cleaning ball transmission seat is made of rubber material as a whole. When the cleaning rubber ball falls on the top of the cleaning ball transmission seat, the cleaning ball transmission seat itself can absorb the impact force in advance.

[0009] As a further description of the above technical solution: the transmission slide and the cleaning ball transmission seat are fixedly connected by screws, and a rubber pad is glued to the bottom of the transmission arm on the peripheral side of the transmission slide. By setting the rubber pad, the impact energy can be absorbed again between the transmission arm and the hydraulic damping rod, thereby improving the buffering effect of the cleaning rubber ball.

[0010] As a further description of the above technical solution: the number of the transmission arms and the hydraulic damping rods is the same, both are 3-6 groups, the positions of the hydraulic damping rods and the transmission arms correspond one to one, and the hydraulic damping rods are located directly below the transmission arms. When the impact force generated by the cleaning rubber ball acts on the transmission slide, the transmission slide drives the transmission arm to move downward, and can squeeze multiple hydraulic damping rods one by one, and the impact force is absorbed by the cooperation of multiple hydraulic damping rods.

[0011] As a further description of the above technical solution: the hydraulic damping rods are spirally arrayed on the circumferential side of the ball receiving cylinder, and the height difference between two adjacent groups of the hydraulic damping rods is 1-3cm. A mounting seat is fixedly installed at the bottom end of the hydraulic damping rod, and the mounting seat is fixedly installed on the ball receiving cylinder by screws. The hydraulic damping rod is fixed to the ball receiving cylinder by the mounting seat, thereby ensuring that the hydraulic damping rod is firmly installed and achieving effective buffering for cleaning rubber balls.

[0012] As a further description of the above technical solution: a connecting flange is provided at the bottom end of the ball collecting cylinder, and a reinforcing ring is fixedly installed at the bottom end of the ball collecting cylinder through the connecting flange. Since a plurality of guide grooves are provided on the circumference of the ball collecting cylinder, a reinforcing ring is provided at the bottom end of the ball collecting cylinder to improve the overall strength of the ball collecting cylinder.

[0013] The utility model has the following beneficial effects:

[0014] The utility model discloses a natural gas pipeline ball receiving cylinder buffer device, which arranges a transmission slide plate and a clamping concave surface in the ball receiving cylinder, and arranges a plurality of groups of spiral array hydraulic damping rods outside the ball receiving cylinder. When the cleaning rubber ball falls into the cleaning ball transmission seat, the cleaning ball transmission seat itself absorbs the energy of the impact first, and then the cleaning ball transmission seat moves downward to squeeze the plurality of hydraulic damping rods in turn, and the energy generated by the impact is absorbed step by step through the cooperation of the plurality of hydraulic damping rods, thereby realizing efficient buffering of the cleaning rubber ball and preventing the impact force of the cleaning rubber ball from causing damage to the ball receiving cylinder and the rubber ball itself.

[0015] The natural gas pipeline ball collecting cylinder buffer device designed by the utility model provides a clamping concave surface cooperating with the cleaning rubber ball on the top of the cleaning ball transmission seat, thereby ensuring that the cleaning rubber ball can accurately fall into the cleaning ball transmission seat when falling, so that the impact force generated by the rubber ball can fully act on the cleaning ball transmission seat, thereby ensuring that the cleaning ball transmission seat cooperates with multiple hydraulic damping rods to effectively buffer the cleaning rubber ball.

[0023] Reference Figure 1-5The utility model provides a natural gas pipeline ball receiving cylinder buffer device: a natural gas pipeline ball receiving cylinder buffer device, comprising a natural gas pipeline 1, a ball receiving cylinder 2, the ball receiving cylinder 2 is fixedly installed at the bottom end of the natural gas pipeline 1, and the interior of the ball receiving cylinder 2 is clamped with a transmission slide 3, the top of the transmission slide 3 is provided with a cleaning ball transmission seat 6, and the top of the cleaning ball transmission seat 6 is provided with a clamping concave surface 11, a plurality of transmission arms 4 are provided on the peripheral side of the transmission slide 3, and the transmission arms 4 extend to the outside of the ball receiving cylinder 2, and a plurality of hydraulic damping rods 7 cooperating with the transmission arms 4 are fixedly installed on the peripheral side of the ball receiving cylinder 2, When the cleaning rubber ball falls into the cleaning ball transmission seat 6, the impact energy is absorbed by the cleaning ball transmission seat 6 itself and multiple groups of hydraulic damping rods 7 to avoid the impact force of the cleaning rubber ball causing damage to the ball collecting cylinder 2 and the rubber ball itself. A guide groove 9 cooperating with the transmission arm 4 is provided on the peripheral side of the ball collecting cylinder 2. By setting the guide groove 9, the transmission arm 4 and the transmission slide plate 3 can be restricted to ensure that when the cleaning rubber ball exerts an impact force on the cleaning ball transmission seat 6 and the transmission slide plate 3, the transmission slide plate 3 moves downward stably, thereby stably transmitting the impact force to the hydraulic damping rod 7 for buffering.

[0024] As a further implementation scheme of the above technical scheme: the cleaning ball transmission seat 6 and the transmission slide plate 3 are provided with mutually matching through holes in the middle. During the cleaning stage of the natural gas pipeline 1, gas and impurities can be discharged along the transmission slide plate 3 at the through hole in the middle of the cleaning ball transmission seat 6. The top of the clamping concave surface 11 and the connection with the inner wall of the ball receiving cylinder 2 have a smooth transition, ensuring that the cleaning rubber ball can stably fall into the clamping concave surface 11 along the natural gas pipeline 1, so that the impact force is fully applied to the transmission slide plate 3, which is convenient for the subsequent multiple hydraulic damping rods 7 to absorb the impact force.

[0025] As a further implementation plan of the above technical solution: the shape of the clamping concave surface 11 is hemispherical, and the size of the clamping concave surface 11 is prepared according to the size of the cleaning rubber ball, ensuring that the cleaning rubber ball can stably fall into the clamping concave surface 11, so that the impact force is completely applied to the transmission slide plate 3, and the cleaning ball transmission seat 6 is made of rubber material as a whole. When the cleaning rubber ball falls on the top of the cleaning ball transmission seat 6, the cleaning ball transmission seat 6 itself can absorb the impact force in advance.

[0026] As a further implementation scheme of the above technical scheme: the transmission slide 3 and the cleaning ball transmission seat 6 are fixedly connected by screws to ensure that the transmission slide 3 and the cleaning ball transmission seat 6 are firmly connected, and at the same time the two can move synchronously. The bottom of the transmission arm 4 on the side of the transmission slide 3 is glued with a rubber pad 5. By setting the rubber pad 5, the impact energy can be absorbed again between the transmission arm 4 and the hydraulic damping rod 7, thereby improving the buffering effect on the cleaning rubber ball.

[0027] As a further implementation scheme of the above technical scheme: the number of transmission arms 4 and hydraulic damping rods 7 is the same, both are 3-6 groups. By setting multiple groups of hydraulic damping rods 7, when the transmission slide plate 3 moves downward, multiple hydraulic damping rods 7 can intervene one by one to achieve efficient buffering of the cleaning rubber ball. The positions of the hydraulic damping rods 7 and the transmission arms 4 correspond one to one, and the hydraulic damping rods 7 are located directly below the transmission arm 4. When the impact force generated by the cleaning rubber ball acts on the transmission slide plate 3, the transmission slide plate 3 drives the transmission arm 4 to move downward, and can squeeze multiple hydraulic damping rods 7 one by one. The impact force is absorbed by the cooperation of multiple hydraulic damping rods 7 to achieve efficient buffering of the cleaning rubber ball.

[0028] As a further implementation scheme of the above technical scheme: the hydraulic damping rods 7 are spirally arrayed on the circumferential side of the ball receiving cylinder 2, and the height difference between two adjacent groups of hydraulic damping rods 7 is 1-3cm. The bottom end of the hydraulic damping rod 7 is fixedly installed with a mounting seat 8, and the mounting seat 8 is fixedly installed on the ball receiving cylinder 2 by screws. The hydraulic damping rod 7 is fixed to the ball receiving cylinder 2 by the mounting seat 8, ensuring that the hydraulic damping rod 7 is firmly installed and at the same time achieving effective buffering for cleaning rubber balls.

[0029] As a further implementation scheme of the above technical scheme: a connecting flange is provided at the bottom end of the ball collecting cylinder 2, and a reinforcing ring 10 is fixedly installed at the bottom end of the ball collecting cylinder 2 through the connecting flange. Since a plurality of guide grooves 9 are provided on the peripheral side of the ball collecting cylinder 2, a reinforcing ring 10 is provided at the bottom end of the ball collecting cylinder 2, which can improve the overall strength of the ball collecting cylinder 2.

[0030] Working principle:

[0031] When the utility model is used, the device is installed at the outlet end of a pipeline that needs to be cleaned, such as a natural gas pipeline 1, by bolts. When cleaning the pipeline, after the cleaning rubber ball enters the ball collecting tube 2 along the pipeline, the cleaning rubber ball directly falls into the clamping concave surface 11 on the top of the cleaning ball transmission seat 6, and the cleaning rubber ball pushes the cleaning ball transmission seat 6 to drive the clamping concave surface 11 and the transmission slide plate 3 to move. Since the cleaning ball transmission seat 6 is made of rubber, the energy generated by the cleaning rubber ball is absorbed in advance by the cleaning ball transmission seat 6 itself, and is transmitted through the transmission arm 4 on the axial side of the transmission slide plate 3 to squeeze the hydraulic damping rods 7 one by one. The energy generated by the cleaning rubber ball is absorbed by the cooperation of multiple hydraulic damping rods 7, so as to avoid the energy generated by the impact of the cleaning rubber ball acting on the ball collecting tube 2 and the cleaning rubber ball itself.
