Description

Technical Field

[0001] The utility model relates to the technical field of grouting pipes, in particular to a grouting device for grouting construction of overburden rock separation layers. Background Art

[0002] After mining underground coal seams, the original rock stress in the overburden above the goaf and coal pillars is destroyed, causing the overburden to move, deform, fracture, and even collapse. This causes ground subsidence, damage to farmland and buildings, and severely harms the ecological environment. During rock movement, multiple delamination zones, consisting of separate layers above the water-conducting fracture zones, can be used for grouting. Grouting pipes are an indispensable part of the overburden delamination grouting process, where holes are drilled into the overburden and grout is injected into the delamination zones.

[0003] Chinese patent document CN221721644U discloses a grouting device for grouting construction of overburden separation layer that is easy to clean, relates to the technical field of grouting pipes, comprises a grouting pipe main body, the upper side of the outer circumferential surface of the grouting pipe main body is provided with a thread groove one, and the outer surface of the thread groove one is threadedly connected with a circular connecting frame. Compared with the existing ordinary grouting pipe, the grouting device for grouting construction of overburden separation layer that is easy to clean can be used for grouting construction of overburden separation layer. By setting the compression spring, after the scraper is attached to the inner wall of the grouting pipe main body, the sliding connecting block can be lifted up by the reset of the compression spring to make the scraper better attached to the interior of the grouting pipe main body, and the slurry remaining on the inner wall of the grouting pipe main body can be quickly scraped off after grouting of the grouting pipe main body is completed, so as to avoid the slurry drying affecting the grouting efficiency of the grouting pipe main body. By setting the circular connecting frame, after the cleaning of the interior of the grouting pipe main body is completed or when the scraper is damaged, the cleaning device can be completely taken out by rotating the handle for quick disassembly and replacement.

[0004] However, in actual use, the utility model cannot hang the slurry remaining on the inner wall of the grouting pipe to the bottom. The slurry will be in long strips on the inner wall, and then the slurry is discharged by gravity or by using a scraper, and the slurry cleaning effect is relatively poor. Utility Model Content

[0005] The main purpose of the utility model is to provide a grouting device for overburden rock separation layer grouting construction, which can effectively solve the problem of relatively poor slurry cleaning effect.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A grouting device for overburden rock separation grouting construction comprises a grouting pipe body. Two support frames are arranged on the inner surface of the grouting pipe body, and a cleaning device is commonly arranged between the two support frames.

[0008] Preferably, the cleaning device includes a sleeve, a rotating rod is rotatably installed on the inner surface of the sleeve, a spiral groove is opened on the inner wall of the sleeve, a vertical groove is opened on the upper end of the rotating rod, a sliding block is slidably installed on the inner surface of the vertical groove, one end of the sliding block is also fixed with a spiral magnet that slides in the spiral groove, and a cleaning component is provided on the outer surface of the sleeve.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 and Figure 2 As shown, a grouting device for overburden delamination grouting construction includes a grouting pipe body 1, two support frames 2 are provided on the inner surface of the grouting pipe body 1, and a cleaning device 3 is provided between the two support frames 2, wherein the support frames 2 are used for the installation of the cleaning device 3, and the two support frames 2 can be designed to be threadedly connected to the grouting pipe body 1 (not shown in the figure), which is convenient for disassembly and assembly, and can improve the grouting efficiency. The support frames 2 and the cleaning device 3 can also be used by other grouting pipe bodies 1, thereby improving the utilization rate of the device and reducing the production and use costs of the device.

[0023] like Figure 2 and Figure 3 As shown, the cleaning device 3 includes a sleeve 31, and a rotating rod 32 is rotatably installed on the inner surface of the sleeve 31. The upper end of the sleeve 31 is also rotatably installed with a handle (not shown in the figure) fixedly connected to the rotating rod 32. The handle is used to drive the rotating rod 32 to rotate. The rotating rod 32 can also be driven to rotate by a motor. A suitable power source is selected according to different usage conditions. A spiral groove 33 is provided on the inner wall of the sleeve 31, and a vertical groove 34 is provided on the upper end of the rotating rod 32. A sliding block 35 is slidably installed on the inner surface of the vertical groove 34. The design of 34 restricting the sliding block 35 makes the sliding block 35 only able to slide up and down in the vertical groove 34. One end of the sliding block 35 is also fixed with a spiral magnet 36 that slides in the spiral groove 33. Since the vertical groove 34 limits the sliding block 35 and the spiral groove 33 limits the spiral magnet 36, the rotating rod 32 can drive the spiral magnet 36 to rotate relative to the grouting pipe body 1 while also moving upward or downward. A cleaning component 37 is provided on the outer surface of the sleeve 31.

[0024] like Figure 4As shown, the cleaning component 37 includes an arc block 371 arranged on the outer wall of the sleeve 31. The material of the arc block 371 is a magnet. Since the spiral magnet 36 also has magnetic force, the spiral magnet 36 will adsorb the arc block 371 and move it on the outer wall of the sleeve 31 when it moves, so that when the spiral magnet 36 rotates and moves up and down relative to the grouting pipe body 1, the arc block 371 will also rotate and move up and down (rotate and move up and down) relative to the grouting pipe body 1. The sleeve 31, the rotating rod 32 and the sliding block 35 are all made of plastic. The plastic material will not be adsorbed by the magnet, which can prevent the sleeve 31 and the rotating rod 32 from interfering with the adsorption effect of the magnet during normal use of the device, thereby affecting the normal operation of the device.

[0025] In addition, a baffle 372 is fixed to the side of the arc block 371 away from the upper end of the sleeve 31 and away from the central axis. A spiral scraper 373 for scraping the inner wall of the sleeve 31 is also fixed to one end of the baffle 372. The baffle 372 can prevent the slurry scraped by the spiral scraper 373 from being squeezed to the upper part of the spiral scraper 373 along the spiral scraper 373, and then adsorbed on the inner wall of the grouting pipe body 1 along the side wall of the spiral scraper 373, thereby affecting the cleaning effect of the device. Figure 3 and Figure 4 As shown, the spiral scraper 373 is in the opposite direction to the spiral groove 33, so that when the spiral scraper 373 rotates and moves downward, the spiral scraper 373 can clean the slurry on the inner wall of the grouting pipe body 1. At the same time, the slurry will gradually flow downward along the inclined surface of the spiral scraper 373, and then be discharged from the bottom of the grouting pipe body 1.

[0026] like Figure 2 and Figure 3 As shown, a limiting block is fixed on the upper outer surface of the sleeve 31. When the equipment is in use, the limiting block is located above the support frame 2 and is used to limit the sleeve 31. At the same time, due to the design of the two support frames 2, the sleeve 31 can be conveniently installed inside the grouting pipe body 1, and the grouting pipe body 1 is placed vertically when the equipment is in use. The limiting block can be stuck above the support frame 2 located above, which is convenient for the installation and use of the device. Moreover, due to the detachable design of the cleaning device 3, the cleaning device 3 will not affect the normal use of the grouting pipe body 1.

[0027] The specific implementation of this embodiment is as follows: when the device is in use, the grouting pipe body 1 is connected to the grouting machine, and then the grouting machine injects grout into the hole through multiple grouting pipe bodies 1 (not shown in the figure, it is a prior art and the present invention will not be described in detail). When the grouting pipe body 1 needs to be cleaned after use, the cleaning device 3 is installed between the two support frames 2, wherein the limit block is stuck at the top of the upper support frame 2, and then the arc block 371 is placed on the outer surface of the casing 31. Since the arc block 371 and the spiral magnet 36 both have a magnetic design, the arc block 371 can be adsorbed on the outer surface of the casing 31, and the arc block 371 can also slide on the outer surface of the casing 31;

[0028] By rotating the rotating rod 32, when the rotating rod 32 rotates, the vertical groove 34 limits the sliding block 35 and the spiral groove 33 limits the spiral magnet 36, so that the spiral magnet 36 can rotate and move downward relative to the sleeve 31. Due to the design of the magnetic connection between the spiral magnet 36 and the arc block 371, the arc block 371 will also rotate and move downward, allowing the spiral scraper 373 to scrape the slurry on the inner wall of the grouting pipe body 1. At the same time, due to the design of the baffle 372, the slurry scraped by the spiral scraper 373 can be prevented from being squeezed to the upper part of the spiral scraper 373 along the spiral scraper 373, thereby reducing the cleaning effect of the device.

[0029] It should be noted that the specific installation method of the grouting pipe body 1, the spiral magnet 36 and the spiral scraper 373 in the present invention belongs to conventional design and will not be elaborated in detail in the present invention.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
