Description

Technical Field

[0001] The utility model relates to the field of crack repair equipment, in particular to a bridge pipe crack blocking device. Background Art

[0002] The gas collecting pipe, bridge pipe and straight pipe are the channels for the discharge of raw coal gas. Once cracks occur, serious smoke and fire may cause serious unorganized emission of smoke, affecting production stability. Common sealing methods include replacing the bridge pipe and manual sealing. If the bridge pipe is replaced, not only will the furnace time be wasted, but the number of furnaces will also be reduced. Not only will the labor and material costs increase, but the loss of raw coal gas will also be caused invisibly. Therefore, the common method for cracks is to manually use a sealing device to seal the pipeline. The specific operation method is to apply casting glue to the crack.

[0003] However, in the prior art, the plugging device is usually applied manually during use, and the effect of the application is affected by work experience. Insufficient experience can easily lead to secondary leakage of the bridge pipe, requiring secondary plugging, which affects production and processing and work continuity.

[0004] After manual application, the colloid needs to be scraped flat with tools. Due to the presence of a certain temperature in the pipeline, there are safety hazards such as scalding during manual application and scraping, and the construction safety is difficult to ensure. Manual scraping can easily lead to uneven distribution of the colloid, making it difficult to achieve uniform sealing.

[0005] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0006] The utility model aims to provide a device for sealing cracks in a bridge pipe, so as to solve the technical defects proposed by the background technology.

[0008] Preferably, the blocking assembly includes a connecting rod and a scraper, the connecting rod is fixedly mounted on one side of the sliding rod, and the scraper is fixedly mounted on an end of the connecting rod away from the scraper.

[0009] Preferably, a moving block is movably installed on the slide rod, and a locking bolt is movably connected to one side of the moving block through a thread, one end of the locking bolt is abutted against the outer surface of the slide rod, and two symmetrically arranged fixed blocks are fixedly installed on the slide rod, and a guide wheel is fixedly installed on the end of the fixed block away from the slide rod, and the guide wheel is located on the side of the scraper away from the slide rod.

[0010] Preferably, the guide wheels are fixedly connected via a rotating rod, and a plurality of fixing plates are fixedly mounted on the rotating rod, and the fixing plates are evenly distributed around the circumference of the rotating rod.

[0011] Preferably, a plurality of fixing rings 1 are fixedly installed on one side of the moving block, and a fixing ring 2 is arranged below the fixing ring 1, and the diameter of the fixing ring 2 is smaller than the diameter of the fixing ring 1.

[0012] Preferably, a scale is provided on the fixed frame, the scale is located on one side of the slide groove, and a pointer is fixedly installed on one side of the slide rod, and the tip of the pointer points to the scale.

[0013] The beneficial effects of the utility model are as follows:

[0014] (1) The utility model uses a fixed frame and a slide rod in coordination. First, the fixed ring one is used to limit and fix the hose body, and the glue outlet is located in the fixed ring two. Then, the fixed frame is placed at the crack of the pipeline, and the fixed ring two is located at the crack. At this time, the fixing bolt is rotated to make it abut against the pipeline, so as to limit and fix the fixed frame, squeeze the hose body and pull the slide rod to make the slider slide in the slide groove. At this time, the slide rod gradually moves, and the colloid is squeezed and attached to the crack of the pipe body. At the same time as the slide rod moves, the connecting rod is used to drive the scraper to move synchronously. Therefore, after the colloid is squeezed and attached to the crack of the pipe body, the scraper is used to scrape the colloid flat so that it completely fits the crack. The sealing effect is not affected by work experience, and the glue is evenly applied, with a good sealing effect.

[0015] (2) The utility model uses the guide wheel and the rotating rod in coordination. When the slide rod moves to apply glue to the crack, the guide wheel moves synchronously with it under the traction of the fixed block. On the one hand, the guide wheel is used to ensure the stability of the glue application process. On the other hand, when the guide wheel rotates, the rotating rod drives the fixed plate to rotate. The rotating fixed plate pushes the air to the glue application area, accelerates the coagulation of the colloid, and further improves the blocking effect.

[0016] In summary, the plugging component provided in the utility model not only achieves uniform plugging, but also the plugging effect is not affected by work experience and the plugging difference is small. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] The present embodiment is used to solve the problem that during use of the plugging device in the prior art, the casting glue is usually applied manually, and the application effect is affected by work experience. Insufficient experience can easily lead to secondary leakage of the bridge pipe, requiring secondary plugging, which affects production and work continuity.

[0028] First, use the fixing ring 1 308 to limit and fix the hose body, and make the glue outlet located in the fixing ring 2 309, then place the fixing frame 1 on the crack of the pipeline, and make the fixing ring 2 309 located at the crack. At this time, rotate the fixing bolt 102 to make it abut against the pipeline, so as to limit and fix the fixing frame 1, squeeze the hose body and pull the slide bar 2 to make the slider 201 slide in the slide groove 101. At this time, the slide bar 2 gradually moves, and the colloid is squeezed out and attached to the crack of the pipe body. While the slide bar 2 moves, the connecting rod 301 is used to drive the scraper 302 to move synchronously. Therefore, after the colloid is squeezed out and attached to the crack of the pipe body, the scraper 302 is used to scrape the colloid flat so that it completely fits the crack. The sealing effect is not affected by work experience, and the glue is evenly applied, with a good sealing effect.

[0029] Embodiment 2:

[0030] This embodiment is used to solve the problem that after manual application, the colloid needs to be scraped flat with a tool. Since the pipeline has a certain temperature, there are safety hazards such as burns during the manual application and scraping process. The construction safety is difficult to ensure, and manual scraping can easily lead to uneven distribution of the colloid, making it difficult to achieve uniform sealing.

[0031] See also Figure 4 - Figure 5 As shown, the utility model also includes a scraper 302, which is fixedly mounted on the end of the connecting rod 301 away from the scraper 302, and two symmetrically arranged fixed blocks 303 are fixedly mounted on the slide bar 2, and a guide wheel 304 is fixedly mounted on the end of the fixed block 303 away from the slide bar 2, and the guide wheel 304 is located on the side of the scraper 302 away from the slide bar 2, and a moving block 202 is movably mounted on the slide bar 2, and a locking bolt 305 is movably connected to one side of the moving block 202 through a thread, and one end of the locking bolt 305 is abutted against the outer surface of the slide bar 2, and the guide wheels 304 are fixedly connected by a rotating rod 306, and a plurality of fixed plates 307 are fixedly mounted on the rotating rod 306, and the fixed plates 307 are evenly distributed around the circumference of the rotating rod 306.

[0032] When the gluing position needs to be adjusted, the locking bolt 305 is rotated to release the lock between the moving block 202 and the slide rod 2, and the moving block 202 is pulled to slide on the slide rod 2, so as to adjust the position of the moving block 202 and then adjust the gluing position, which has a wide range of applications.

[0033] When the slide bar 2 moves to apply glue to the crack, the guide wheel 304 moves synchronously with it under the traction of the fixed block 303. On the one hand, the guide wheel 304 is used to ensure the stability of the glue application process. On the other hand, when the guide wheel 304 rotates, the fixed plate 307 is driven to rotate through the rotating rod 306. The rotating fixed plate 307 is used to push air to the glue application area to accelerate the coagulation of the colloid and further improve the sealing effect.

[0034] In combination with Example 1 and Example 2, through the coordinated use of the slide bar 2 and the slider 201, first, the fixing frame 1 is fixedly installed on the pipeline using the fixing bolt 102, the rubber hose is squeezed and the slide bar 2 is pulled at the same time, and the rubber hose is driven to move while squeezing the glue until the crack is covered. While moving, the scraper 302 is used to smooth the colloid so that the colloid completely fits the crack. The sealing effect is not affected by work experience, and the glue is evenly applied to effectively avoid the occurrence of secondary sealing, and the sealing effect is good.

[0035] The working process and principle of the utility model are as follows:

[0036] First, the fixing ring 1 308 is used to limit and fix the hose body, and the glue outlet is located in the fixing ring 2 309. Then, the fixing frame 1 is placed at the crack of the pipeline, and the fixing ring 2 309 is located at the crack. At this time, the fixing bolt 102 is rotated to make it abut against the pipeline, so as to limit and fix the fixing frame 1, squeeze the hose body and pull the slide bar 2 to make the slider 201 slide in the slide groove 101. At this time, the slide bar 2 gradually moves, and the colloid is squeezed and attached to the crack of the pipe body. While the slide bar 2 moves, the connecting rod 301 is used to drive the scraper 302 to move synchronously. Therefore, after the colloid is squeezed and attached to the crack of the pipe body, the scraper 302 is used to scrape the colloid flat so that it completely fits the crack. The sealing effect is not affected by work experience, and the glue is evenly applied, and the sealing effect is good.

[0037] Furthermore, when the slide bar 2 moves to apply glue to the crack, the guide wheel 304 moves synchronously with it under the traction of the fixed block 303. On the one hand, the guide wheel 304 is used to ensure the stability of the glue application process. On the other hand, when the guide wheel 304 rotates, the fixed plate 307 is driven to rotate through the rotating rod 306. The rotating fixed plate 307 pushes air to the glue application area to accelerate the coagulation of the colloid and further improve the blocking effect.

[0038] The utility model not only realizes uniform blocking by setting the blocking component 3, but also the blocking effect is not affected by work experience and the blocking difference is small.
