Description

Technical Field

[0001] The utility model relates to the technical field of pipeline systems of pipe cleaning balls, in particular to a safe guide rail type two-way ball sending and receiving device. Background Art

[0002] At present, the end cover of the common ball-launching device on the market is of blind plate type, which is fixedly connected to the ball-launching pipe by a clamp. When there is pressure in the system, an operator rashly loosens the clamp, and the clamp flies out under the high pressure, creating a huge safety hazard. At the same time, the common pipe cleaning ball sending station and recycling station are not universal. The pipe cleaning ball can only move in one direction inside, and cannot achieve two-way movement of the pipe cleaning ball in the system, resulting in a low degree of automation of the supporting system.

[0003] At the same time, the conventional ball sending and receiving device also needs to be equipped with a special ball receiving trolley and recovery valve. The problems are: 1. The impact force of the cleaning ball on the ball receiving trolley is relatively large, which often damages the trolley. The sealing cover of the trolley is often blown off under the huge air pressure, which is a major safety hazard; 2. If the recovery valve between the pipeline and the ball receiving workshop fails, materials may enter the ball receiving trolley, resulting in a safety hazard of material explosion; 3. The system needs to be equipped with more control valves and ball receiving trolleys, which is costly.

[0004] In order to solve the above problems of the traditional ball serving and receiving device, we propose a ball serving and receiving device which is safe and reliable, easy to operate, moderately priced, and can improve the automation level of the supporting system. Utility Model Content

[0005] The purpose of the present invention is to provide a safe rail-type two-way ball-receiving and serving device to solve the above-mentioned deficiencies in the technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a safe rail-type two-way ball receiving and serving device, comprising a sealing end cover, a serving tube and a sealing ring, wherein the sealing end cover is spirally connected to the serving tube and is sealed by the sealing ring, so that the sealing end cover and the serving tube form a closed environment, a shock-absorbing piston mechanism is provided between the inner side of the sealing end cover and the serving tube to reduce the impact of the cleaning ball, and a positioning pin operating mechanism is also provided on the outer side of the sealing end cover;

[0007] The damping piston mechanism includes a piston sleeve, a damping spring and a piston rod. The piston sleeve is fixed on the inner side of the sealing end cover, the piston rod is installed in the piston sleeve, and the damping spring is installed in the piston sleeve and is located between the piston sleeve and the piston rod and is in a compressed state.

[0008] Furthermore, a circular handle is welded and fixed to the periphery of the sealing end cover away from the serving tube.

[0009] Furthermore, a mechanical lock buckle is welded and fixed to the outer periphery of the sealing end cover by the serving tube, and a mechanical locking buckle is welded and fixed to the serving tube for locking with the mechanical lock buckle. When the sealing end cover is rotated into place, the mechanical lock buckle is aligned with the mechanical locking buckle, so that the buckle screw on the mechanical lock buckle can just fall into the fixed buckle U-groove of the mechanical locking buckle.

[0010] Furthermore, the serving tube is provided with a first channel, a second channel, a third channel and a fourth channel, the first channel and the second channel are adjacently arranged at the periphery close to one end of the sealing end cover, and the third channel is provided corresponding to the first channel, and the fourth channel is located at the end corresponding to the sealing end cover, the first channel, the second channel, the third channel and the fourth channel correspond to the air intake, exhaust, material dropping and material main channels respectively.

[0011] Furthermore, the sealing end cover is provided with two pins which are fixed on the sealing end cover at a 120-degree distribution and extend beyond the inner wall of the sealing end cover. The pins also match the guide groove of the serving tube so that the serving tube can slide freely in the guide groove.

[0012] Furthermore, a ball-turning boss is provided near the middle of the ball-launching tube, and both sides of the ball-turning boss are designed with variable diameters. When the pipe cleaning ball passes through the side with a larger pipe diameter, the scraper blades are unfolded, and when the ball is pushed in the reverse direction, the pipe cleaning ball can smoothly turn over by passing through the ball-turning boss scraper blades.

[0013] Furthermore, three guide grooves evenly spaced at 120 degrees are opened on the outside of the serving tube. The entrance end of the guide groove is wider to facilitate the pin on the sealing end cover to enter the groove, and the width of the middle and rear sections of the guide groove is the same as the diameter of the pin.

[0014] Furthermore, a positioning pin hole is provided at the very end of the guide slot, the diameter of the positioning pin hole is equal to the width of the guide slot, and the depth is greater than the depth of the guide slot. When the sealing end cover slides to the end of the guide slot with the pin, the movable positioning pin will enter the positioning pin hole under the pressure of the compression spring, thereby positioning the sealing end cover and locking it.

[0015] Furthermore, an anti-slip U-groove is provided at the end of the guide groove and is located behind the positioning pin hole. The depth is the same as that of the guide groove. When the movable positioning pin slips out of the positioning pin hole under pressure in the pipeline, the sealing end cover will move backward to allow the pin to slide into the anti-slip U-groove.

[0016] Furthermore, the positioning pin operating mechanism includes a movable positioning pin, a compression spring, a guide sleeve and a handle. The guide sleeve is hollow and is installed on the sealing end cover. The movable positioning pin is located in the guide sleeve and passes through the sealing end cover to cooperate with the positioning pin hole of the serving tube. The compression spring is located in the guide sleeve and presses the movable positioning pin so that the movable positioning pin sinks into the positioning pin hole. The handle passes through the guide sleeve and the compression spring and is threadedly connected to the movable positioning pin.

The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0035] Example 1

[0036] like Figure 1-3As shown, the utility model provides a technical solution: a safe rail-type two-way ball receiving and serving device, comprising a sealing end cover 1, a serving tube 2 and a sealing ring 3, wherein the sealing end cover 1 is spirally connected to the serving tube 2 and is sealed by the sealing ring 3, so that the sealing end cover 1 and the serving tube 2 form a closed environment to meet the corresponding airtightness requirements, a shock-absorbing piston mechanism is provided between the inner side of the sealing end cover 1 and the serving tube 2 to reduce the impact of the cleaning ball, and a positioning pin operating mechanism is also provided on the outer side of the sealing end cover 1;

[0037] The shock-absorbing piston mechanism includes a piston sleeve 4, a shock-absorbing spring 5 and a piston rod 6. The piston sleeve 4 is fixed on the inner side of the sealing end cover 1, the piston rod 6 is installed in the piston sleeve 4, the shock-absorbing spring 5 is installed in the piston sleeve 4, and is located between the piston sleeve 4 and the piston rod 6, and is in a compressed state. When the pipe cleaning ball hits the piston rod 6, the piston rod 6 compresses the shock-absorbing spring 5 to achieve the effect of reducing the impact of the pipe cleaning ball.

[0038] Example 2

[0039] like Figure 1-3 As shown, a circular handle 12 is welded and fixed to the periphery of the sealing end cover 1 away from the serving tube 2 to facilitate the rotation of the sealing end cover 1.

[0040] A mechanical lock buckle 13 is welded and fixed to the periphery of the sealing end cover 1 against the serving tube 2, and a mechanical locking buckle 14 is welded and fixed to the serving tube 2 for locking with the mechanical lock buckle 13. When the sealing end cover 1 is rotated into place, the mechanical lock buckle 13 is aligned with the mechanical locking buckle 14, so that the buckle screw on the mechanical lock buckle 13 can just fall into the fixed buckle U groove of the mechanical locking buckle 14.

[0041] The serving tube 2 is provided with a first channel 21, a second channel 22, a third channel 23 and a fourth channel 24. The first channel 21 and the second channel 22 are arranged adjacent to each other at the periphery of one end close to the sealing end cover 1, and the third channel 23 is arranged corresponding to the first channel 21, and the fourth channel 24 is located at the end corresponding to the sealing end cover 1. The first channel 21, the second channel 22, the third channel 23 and the fourth channel 24 respectively correspond to the air intake, exhaust, blanking and material main channels and are then connected.

[0042] The sealing end cover 1 is provided with two pins 7 which are fixed on the sealing end cover 1 at a 120-degree distribution and extend beyond the inner wall of the sealing end cover 1 . The pins 7 also match the guide groove 16 of the serving tube 2 so that the serving tube 2 can slide freely in the guide groove 16 .

[0043] A ball turning boss 15 is arranged near the middle of the ball serving tube 2, and both sides of the ball turning boss 15 are designed with variable diameters. When the pipe cleaning ball passes through the large diameter side, the scraper blade is unfolded. When the pipe cleaning ball passes through the ball turning boss 15 and the scraper blade can be smoothly turned over when the ball is pushed in the reverse direction.

[0044] The outside of the serving tube 2 is provided with three guide grooves 16 evenly spaced at 120 degrees. The entrance end of the guide groove 16 is wider to facilitate the pin 7 on the sealing end cover 1 to enter the groove, and the width of the middle and rear sections of the guide groove 16 is the same as the diameter of the pin 7 to accurately locate the direction of the pin 7.

[0045] A positioning pin hole 17 is provided at the end of the guide slot 16. The diameter of the positioning pin hole 17 is equal to the width of the guide slot 16, and the depth is greater than the depth of the guide slot 16. When the sealing end cover 1 slides to the end of the guide slot 16 along with the pin 7, the movable positioning pin 8 will enter the positioning pin hole 17 under the pressure of the compression spring 9, thereby positioning the sealing end cover 1 and locking it.

[0046] An anti-slip U-groove 18 is provided at the end of the guide slide groove 16 and is located behind the positioning pin hole 17. The depth is the same as that of the guide slide groove 16. When there is pressure in the pipeline and the movable positioning pin 8 slips out of the positioning pin hole 17, the sealing end cover 1 will move backward, causing the pin 7 to slide into the anti-slip U-groove 18 and will not completely slip out, thereby avoiding the occurrence of safety accidents.

[0047] The positioning pin operating mechanism includes a movable positioning pin 8, a compression spring 9, a guide sleeve 10 and a handle 11. The guide sleeve 10 is hollow and is installed on the sealing end cover 1. The movable positioning pin 8 is located in the guide sleeve 10 and passes through the sealing end cover 1 to cooperate with the positioning pin hole 17 of the serving tube 2. The compression spring 9 is located in the guide sleeve 10 and presses the movable positioning pin 8 so that the movable positioning pin 8 sinks into the positioning pin hole 17. The handle 11 passes through the guide sleeve 10 and the compression spring 9 and is threadedly connected to the movable positioning pin 8.

[0048] The working principle of this rail-type two-way ball receiving and sending device:

[0049] 1) The following are the installation instructions for the two-way ball receiving and sending device:

[0050] When it is necessary to close the cover, first lift the handle 11 upwards by hand, the compression spring 9 is compressed, and at the same time, the movable locating pin 8 is driven to move upwards, aligning the two pins 7 with the entrance of the guide slot 16 of the serving tube 2, and pushing the sealing end cover 1 forward at the same time. When the pin 7 enters the guide slot 16, the handle 11 can be released. At this time, the movable locating pin 8 is pressed against the guide slot 16 under the pressure of the compression spring 9, and continues to push forward and rotate the sealing end cover 1 along the guide slot 16. When the movable locating pin 8 falls just above the locating pin hole 17, under the pressure of the compression spring 9, the movable locating pin 8 falls into the locating pin hole 17, fixing the sealing end cover 1 on the serving tube 2. At this time, the mechanical lock buckle 13 and the mechanical locking buckle 14 are just aligned, locking the two together, and playing a double protection role. At the same time, since the gap between the sealing end cover 1 and the serving tube 2 is smaller than the diameter of the sealing ring 3, the sealing ring 3 is squeezed to achieve a sealing effect.

[0051] 2) The following are instructions for disassembling the sealing end cover 1 under pressure:

[0052] When it is necessary to remove the sealing end cover 1, first open the mechanical safety lock 13 / 14, then lift the handle 11 upwards, and the movable locating pin 8 will disengage from the locating pin hole 17. Due to the pressure in the pipeline, the sealing end cover 1 will be subjected to a backward force, causing the pin 7 to fall into the anti-detachment U-groove 18. Due to the obstruction of the anti-detachment U-groove 18, the sealing end cover 1 cannot be ejected directly, which plays a role in pressurized safety protection. When the pressure in the pipeline is discharged, push the end cover forward to disengage the pin 7 from the anti-detachment U-groove 18. At this time, lift the handle 11 and rotate the sealing end cover 1 to remove it. At the same time, when there is pressure in the system, the friction between the movable locating pin 8 and the locating pin hole 17 will also increase, and the force required to pull up the handle 11 will also increase, which also plays a certain protective role and greatly reduces the safety risk.

[0053] 3) The following is the description of the pipe cleaning ball flanging, such as Figure 5 As shown:

[0054] When the system performs the cleaning task, in order to ensure that the pipeline can be effectively cleaned, the cleaning ball diaphragm bends and deforms in the opposite direction of the forward direction in the pipeline, and the deformation is relatively large. When the cleaning ball reaches the recycling station pipeline, the diaphragm enters the reverse step. Since the diameter of the front pipe is slightly larger, the diaphragm is stretched to a certain extent, which reduces the friction between the diaphragm and the pipe wall, but still maintains a close fit with the pipeline, such as the change from ① to ② (see details). Figure 5 ), when the pipe cleaning ball starts to move in the reverse direction, the deformation direction of the diaphragm is consistent with the movement direction. Since the friction between the diaphragm and the pipe wall is small at this time, the pipe cleaning ball can move forward smoothly. When the diaphragm moves to the reverse step, the friction gradually increases due to the gradual decrease in the pipe diameter. At the same time, under the effect of the rear thrust, the diaphragm begins to reverse backward. When both diaphragms pass the reverse step, the pipe cleaning ball achieves complete reverse movement, such as the changes from ③ to ④ (see details). Figure 5 ), when the cleaning ball returns to the sending station, the cleaning ball diaphragm changes as ①-② (see details Figure 5 ), and so on, thus realizing the two-way sending and receiving of the cleaning ball.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
