Description

Technical Field

[0001] The invention relates to an auxiliary installation device, in particular to a portable device for auxiliary installation of a fire protection pipeline sealing ring. Background Art

[0002] Firefighting pipes refer to pipe materials used in firefighting to connect firefighting equipment and devices and to transport firefighting water, gas or other media. Due to special needs, the thickness and material of firefighting pipes have special requirements, and they are sprayed with red paint to transport firefighting water.

[0003] When installing fire-fighting pipes, it is usually necessary to butt the pipes. When butt-jointing the fire-fighting pipes, it is necessary to put a rubber sealing ring on the joint. The rubber sealing ring is usually put on manually. The rubber sealing ring is manually put on one of the pipes, and then the two fire-fighting pipes are butt-jointed. Then the rubber sealing ring is pushed toward the joint of the pipes. It is laborious to push the rubber sealing ring. The rubber sealing ring needs to cover the joint of the pipes, and then the lubricant is manually poured on the rubber sealing ring. By applying the lubricant on the rubber sealing ring, the buckle can be more tightly connected with the sealing ring when installing the buckle, so that the joint of the pipes can be better sealed.

[0004] In the existing technical solutions, a Chinese patent with patent application number 202021593745.0 discloses a handheld fire-fighting pipe installation sleeve sealing ring device, including a first handle, etc.; an opening mechanism is connected to the bottom of the first handle, and a pushing mechanism is connected to the bottom of the opening mechanism. The utility model can quickly put the sealing rubber ring on the fire pipe through the cooperation of the propping mechanism and the pushing mechanism, and the sealing rubber ring will not be deformed when being put on, so the sealing rubber ring is effectively protected. However, the problem with the device is that the sealing rubber ring can only be put on one of the pipes, and the sealing rubber ring usually needs to be put on the butt joint of the pipes. The pipes are sealed by putting the sealing rubber ring on the butt joint, but putting the rubber ring on one of the pipes still needs to be manually pushed toward the butt joint of the pipes, which is still laborious, and after the sealing rubber ring is put on the butt joint of the pipes, it is necessary to manually sprinkle lubricating liquid on the rubber ring. By applying lubricating liquid on the rubber sealing ring, the buckle can be more tightly connected with the sealing ring when installing the buckle, but the device lacks the function of sprinkling lubricating liquid on the sealing rubber ring after the sealing rubber ring is put on the butt joint of the pipes.

[0005] Manually adjusting the rubber sealing ring requires a lot of effort and is labor-intensive. The adjustment position is not accurate enough and it takes time to adjust it manually. In addition, the lubricant is not evenly poured on the rubber sealing ring manually. Therefore, a portable fire pipe sealing ring auxiliary installation device has been developed, which can automatically put the rubber sealing ring on the pipe joint and evenly spray the lubricant when installing the rubber sealing ring. Summary of the invention

[0006] In order to overcome the shortcomings that manual adjustment of the rubber sealing ring requires great effort, is labor-intensive, the adjustment position is not accurate enough, it is time-consuming to adjust manually after adjustment, and the lubricating liquid is not evenly poured on the rubber sealing ring when it is manually poured, the purpose of the present invention is to provide a portable fire protection pipe sealing ring auxiliary installation device that can automatically put the rubber sealing ring on the pipe joint and can evenly spray the lubricating liquid when installing the rubber sealing ring.

[0023] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified. Example

[0024] A portable device for assisting the installation of fire protection pipe sealing rings, such as Figure 1-Figure 6As shown, it includes a carrying handle 1, a right housing 2, a right sliding housing 3, an electric push rod 7, a connection block 8, a reset spring 9, a load hook 901, a left housing 10, a rotating shaft sleeve 1001, a left rotating housing 11, a protrusion 1101, a rotating rack 12, a motor seat 13, a rotating motor 14 and a rotating gear 15. The right side of the carrying handle 1 is fixedly connected to the right housing 2, and a through hole for allowing a pipe to pass through is opened at the center of the right housing 2. The right sliding housing 3 is slidably connected to the right housing 2, and the right sliding housing 3 can be on the right The right sliding shell 3 slides on the housing 2 but will not fall off. A through hole is opened at the center of the right sliding shell 3. The through hole on the right sliding shell 3 has the same diameter as the through hole on the right housing 2. An electric push rod 7 is installed in the right housing 2. The driving shaft of the electric push rod 7 is fixedly connected to the right sliding shell 3. When the electric push rod 7 is extended, it will push the right sliding shell 3 to slide away from the right housing 2. Four connecting blocks 8 are fixedly connected to the left end surface of the right sliding shell 3 in a circular array. A cavity slide groove is opened in the connecting block 8. A return spring 9 is installed in each connecting block 8. The connecting block 8 is slidably connected with a load hook 901. When the load hook 901 slides toward the direction close to the right sliding shell 3, the reset spring 9 is compressed. The load hook 901 is slidably connected with the connecting block 8. The left end of the carrying handle 1 is fixedly connected with a left shell 10. A through hole is provided at the center of the left shell 10 for allowing a pipe to pass through. The through hole on the left shell 10 has the same diameter as the through hole on the right shell 2. A rotating shaft sleeve 1001 is installed in the left shell 10. The rotating shaft sleeve 1001 is connected with a left rotating shell 11. A protrusion 1101 is fixedly connected to the shell 11, and a rotating rack 12 is fixedly connected to the left rotating shell 11. The rotating rack 12 is annular and connected to the rotating shaft sleeve 1001. A motor seat 13 is fixedly connected to the left shell body 10, and a rotating motor 14 is installed on the motor seat 13. A rotating gear 15 is fixedly connected to the rotating shaft of the rotating motor 14. The rotating gear 15 and the rotating rack 12 are meshed, so that when the rotating gear 15 rotates, it will drive the rotating rack 12 to rotate, thereby driving the left rotating shell 11 to rotate.

[0025] When it is necessary to put rubber sealing rings on the two pipes, the rubber sealing rings to be installed are first put on the four load hooks 901 manually, and then one pipe is inserted from the central through hole of the right shell 2 to the direction close to the left shell 10, and then the other pipe is inserted from the central through hole of the left shell 10 to the direction close to the right shell 2, and then the two pipes are docked, and the docking position of the two pipes is located between the left rotating shell 11 and the rubber sealing ring, and then the electric push rod 7 is started to push the right sliding shell 3 toward the direction close to the left rotating shell 11, thereby driving the connecting block 8 to move toward the direction close to the left rotating shell 11, thereby driving the load hook 901 to move toward the direction close to the left rotating shell 11, thereby driving the rubber sealing ring to move toward the direction close to the left rotating shell 11, when the rubber sealing ring is located between the two When the pipe is at the docking position, the electric push rod 7 is stopped, and then the rotating motor 14 is started, thereby driving the rotating gear 15 to rotate, thereby driving the left rotating shell 11 to rotate through the rotating rack 12, thereby driving the protrusion 1101 to rotate. When the protrusion 1101 contacts the load-bearing hook 901 and continues to rotate, the protrusion 1101 will slide the load-bearing hook 901 away from the left rotating shell 11, and at the same time compress the reset spring 9, so that the rubber sealing ring is separated from the load-bearing hook 901. When the rubber sealing ring is separated from one load-bearing hook 901, the part of the rubber sealing ring that is separated from the load-bearing hook 901 will be sleeved on the docking position of the pipe. After the protrusion 1101 rotates one circle, the rubber sealing ring is separated from the four load-bearing hooks 901, so that the rubber sealing ring is sleeved on the pipe docking position. Example

[0026] On the basis of Example 1, Figure 8-Figure 10 As shown, it also includes a connecting ring 4 and a roller 6. The connecting ring 4 is fixedly connected to the left rotating shell 11, and 8 rolling grooves 5 are opened in a circular array on the connecting ring 4. The rolling grooves 5 are rotatably connected to the rollers 6. The right sliding shell 3 is also provided with 8 rolling grooves 5 in a circular array, and the rolling grooves 5 on the right sliding shell 3 are also rotatably connected to the rollers 6. The rotation of the rollers can make it more convenient for people to wear pipes in the left rotating shell 11 and the right sliding shell 3.

[0027] When the pipe needs to be passed through the through hole at the center of the right shell 2 and the left shell 10, the outer wall of the pipe will contact the roller 6, and when passing the pipe, the roller 6 will rotate under the friction of the pipe, so that people can pass the pipe through the through hole at the center of the right shell 2 and the left shell 10 more quickly, thereby improving work efficiency. Example

[0028] On the basis of Example 2, Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, it also includes a clamping mechanism, which includes a first clamping ring 18, a first rack 19, a first magnet 20, a resistance washer 21, a second clamping ring 22, a second magnet 2201, a second rack 23, a connecting shaft 24, a switch gear 25 and a switch knob 26. The right shell 2 and the left shell 10 are both provided with a first slide groove 16, and the right shell 2 and the left shell 10 are both provided with a second slide groove 17. The first clamping ring 18 is slidably connected in the first slide groove 16. The main body shape of the first clamping ring 18 is a semicircular ring. The first rack 19 is fixed to the first clamping ring 18. The first rack 19 is fixed to the first clamping ring 18 through a support rod. The first magnet 20 is installed on the upper and lower sides of the first clamping ring 18. The first clamping ring 18 is fixed with a resistance washer 21. The resistance washer 21 is a semicircular ring and is made of rubber. It can increase the friction between the pipe and the rubber. The second clamping ring 22 is elastic so it will not damage the pipeline. The second sliding groove 17 is slidably connected with a second clamping ring 22, and the second clamping ring 22 is fixedly connected with a second rack 23. The main body of the second clamping ring 22 is a semicircular ring of the same size as the first clamping ring 18. The second clamping ring 22 is also installed with a resistance washer 21. The upper and lower sides of the second clamping ring 22 are installed with a second magnet 2201. When the second magnet 2201 and the first magnet 20 are close, they will attract each other. The first clamping ring 18 and the second clamping ring 22 can clamp the pipeline by sucking the second magnet 2201 and the first magnet 20. A connecting shaft 24 is fixedly connected to the right shell 2 and the left shell 10, and a switch gear 25 is rotatably connected to the connecting shaft 24. The switch gear 25 is located between the first rack 19 and the second rack 23. The switch gear 25 is simultaneously meshed with the first rack 19 and the second rack 23 on the same side, and a switch knob 26 is fixedly connected to the switch gear 25.

[0029] When it is necessary to pass the pipe through the through hole at the center of the right shell 2, the switch knob 26 on the right side is rotated clockwise by hand, thereby driving the switch gear 25 on the right side to rotate clockwise, thereby driving the first rack 19 on the right side to move in the direction away from the second clamping ring 22 on the right side, thereby driving the first clamping ring 18 on the right side to slide in the direction away from the second clamping ring 22 on the right side, thereby driving the second rack 23 on the right side to move in the direction away from the first clamping ring 18 on the right side, thereby driving the second clamping ring 22 on the right side to slide in the direction away from the first clamping ring 18 on the right side, and then the pipe is passed through the through hole at the center of the right shell 2 in the direction close to the left shell 10; when it is necessary to pass the pipe through the through hole at the center of the left shell 10, the switch knob 26 on the left side is rotated counterclockwise by hand, thereby driving the switch gear 25 on the left side to rotate counterclockwise, thereby driving the first rack 19 on the left side to move in the direction away from the second clamping ring 22 on the left side, thereby driving the first clamping ring 1 8 slides in the direction away from the second clamping ring 22 on the left side, thereby driving the second rack 23 on the left side to move in the direction away from the first clamping ring 18 on the left side, thereby driving the second clamping ring 22 on the left side to slide in the direction away from the first clamping ring 18 on the left side, and then the pipe is inserted from the through hole at the center of the left shell 10 to the direction close to the right shell 2; when the rubber sleeve is to be put on the pipe, the switch knob 26 is turned by hand to make the second clamping rings 22 on both sides slide in the direction close to the first clamping ring 18. When the second clamping ring 22 and the first clamping ring 18 are far apart, the second magnet 2201 and the first magnet 20 will attract each other, thereby clamping the pipe, and the resistance washer 21 can effectively prevent the pipe from rotating and sliding during the installation process, so that the clamping mechanism can clamp the pipe for anti-skid treatment, prevent the pipe from being unstable when the rubber sealing ring is installed, thereby preventing the sealing effect of the rubber sealing ring from being affected by the unstable pipe docking.

[0030] It also includes a feeding ring 27, a spray gun 28 and a trigger wrench 29. The feeding ring 27 is fixedly connected to the left shell body 10. The feeding ring 27 is a circular ring with a notch, and the notch is inclined and sloped, which is convenient for the sliding of the trigger wrench 29. When the rubber sealing ring is not put on the pipeline, the trigger wrench 29 is located at the notch of the feeding ring 27. The left rotating shell body 11 is equipped with a spray gun 28, and lubricating liquid is stored in the spray gun 28. The trigger wrench 29 is installed on the spray gun 28. Pressing the trigger wrench 29 can trigger the spray gun 28 to spray the lubricating liquid.

[0031] When the rubber sealing ring is put on the butt joint of the pipe and the left rotating shell 11 is rotated, the muzzle of the spray gun 28 is aimed at the rubber sealing ring, thereby driving the spray gun 28 to rotate, and when the trigger wrench 29 of the spray gun 28 moves from the gap of the feed ring 27 to the feed ring 27, the feed ring 27 presses the trigger wrench 29, so that the spray gun 28 sprays the lubricating liquid onto the rubber ring. When the spray gun 28 rotates one circle driven by the left rotating shell 11, the entire circle of the rubber sealing ring can be evenly sprayed with the lubricating liquid, so that the rubber sealing ring can be sprayed with the lubricating liquid while installing the rubber sealing ring, which is convenient for subsequent processing of the butt joint pipe with the rubber sealing ring, thereby improving work efficiency.
