Description

Technical Field

[0001] The utility model relates to the technical field of coal drop pipe cleaning, in particular to a lifting and adjusting multi-thickness automatic blockage clearing device for a coal drop pipe. Background Art

[0002] A coal drop pipe is a commonly used means of transporting coal blocks, most of which are pipeline structures. Since coal blocks are prone to blockage during transportation in the pipeline, a cleaning device is required to extend into the pipeline from the outside to break up the blockage layer to ensure the normal transportation of the coal blocks. However, the traditional cleaning device is limited by length issues and cannot clean the blockage layer deep in the pipeline. In addition, due to the different thicknesses of the blockage layer, the blockage layer cannot be broken up quickly, resulting in low cleaning efficiency. Therefore, a lifting and adjusting multi-thickness automatic clearing device for the coal drop pipe is needed to meet the needs.

[0003] Chinese patent CN219597584U discloses an automatic blockage clearing device for a coal drop pipe, comprising a pipe body, a head adjustment mechanism disposed inside the pipe body, a blockage clearing mechanism disposed inside the pipe body, the adjustment mechanism comprising a first motor fixedly connected to the pipe body, an adjustment screw fixedly connected to the output shaft of the first motor, a threaded sleeve connected to the outer thread of the adjustment screw, and a connecting rod fixedly connected to one side of the threaded sleeve. This solution drives the adjustment screw to rotate by the first motor, and then drives the threaded sleeve and the connecting rod to move by the rotation of the adjustment screw, so that the connecting rod drives the installation box to move, thereby facilitating the lifting and lowering adjustment of the blockage clearing mechanism to adapt to blockages of different thicknesses. By providing a telescopic cylinder to drive the displacement of the blockage clearing mechanism, it is convenient to continuously and deeply process the blockage clearing process.

[0004] There are still several points for improvement in the above scheme: the cleaning device can only be used for coal drop pipes of corresponding sizes, has low versatility and is easily stopped at the intersection of the tee pipe; the drill bit is more troublesome to install and wears out greatly after long-term use, and cannot be replaced quickly. Utility Model Content

[0005] In order to solve the problems of the existing technology, the utility model provides a lifting and adjusting multi-thickness automatic blockage clearing device for a coal drop pipe, comprising a base and a lifting rod installed on the base for lifting and adjusting, a tensioner adapted to the diameter of the coal drop pipe and a drill barrel for clearing blockages. The tensioner is provided with a ball for reducing the friction between itself and the pipe wall, a scraping brush for cleaning attachments on the pipe wall and a connecting rod for synchronously connecting the ball and the scraping brush. The lifting rod is installed at the center of the upper surface of the base, the tensioner is installed on the top of the lifting rod, the drill barrel is installed on the top of the tensioner, the balls are arranged in an array at upper and lower ends on the side of the tensioner, the connecting rod is arranged between the balls at the upper and lower ends, and the scraping brush is installed at the center of the connecting rod and connected to the side of the tensioner.

[0006] Preferably, the rolling ball is connected with a fitting joint and a telescopic rod. Mounting holes are arranged in an array on the side surface of the expander. The fitting joint semi-surrounds the rolling ball, and the telescopic rod is located in the mounting hole and connected with the fitting joint.

[0007] Preferably, a spring is arranged outside the telescopic rod. One end of the spring is connected to the bottom of the fitting joint, and the other end is connected to the bottom of the mounting hole. A positioning hole is arranged on the side surface of the fitting joint.

[0008] Preferably, a threaded bracket and a plug rod are arranged on the wiper. A jack is arranged on the side surface of the expander.

[0009] Preferably, a ring bracket is arranged at the center of the connecting rod, and a threaded hole is arranged at the center of the ring bracket.

[0010] Preferably, a motor is arranged at the connection between the lifting rod and the expander. A sleeve is arranged at the top of the motor and is rotationally connected with the expander.

[0011] Preferably, a drill bit and a rotor are arranged on the drill barrel. The drill bit is installed at the top of the drill barrel, and the rotors are arranged in an array on the side surface of the drill barrel.

[0012] Preferably, a clamping strip is arranged on the drill bit. A rotating shaft is installed at the bottom of the drill bit, and a fitting groove is arranged at the center of the drill barrel.

[0013] The beneficial effects of the present utility model compared with the prior art are as follows:

[0014] 1. The present utility model uses an expander to adapt to coal chutes with different pipe diameters, and has strong versatility. Specifically, when not entering the coal chute, the distance from the top of the fitting joint to the center of the expander is greater than the pipe diameter of the coal chute. The spring enables the fitting joint to have a certain reset ability, and the telescopic rod is used to extend and contract the fitting joint.

[0015] 2. The present utility model can quickly install and disassemble the drill bit to ensure that the cleaning efficiency of the blocked layer will not be reduced.

By dividing the drill bit and the drill barrel into independent components and then assembling them, it is convenient to replace the drill bit.

[0016] 3. The present utility model uses a connecting rod to prevent the cleaning device from being stuck at the intersection of the tee. Specifically, rolling balls are arranged on the upper and lower sides of the expander. When the upper rolling ball passes through the intersection, the lower rolling ball fits against the pipe wall. The connecting rod restricts the displacement of the wiper and the upper rolling ball. When the upper rolling ball passes through the intersection and the lower rolling ball passes through the intersection, the upper rolling ball fits against the pipe wall, and the connecting rod restricts the displacement of the wiper and the lower rolling ball.

Detailed implementation mode

[0024] To further understand the features, technical means, specific purposes and functions achieved by the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific implementation modes.

[0025] See Figures 1 to 6 As shown, a lifting - adjustable multi - thickness automatic blockage - clearing device for a coal - dropping pipe includes a base 1, a lifting rod 6 installed on the base 1 for lifting adjustment, a tensioner 2 adapted to the diameter of the coal - dropping pipe, and a drill barrel 7 for clearing blockages. The tensioner 2 is provided with balls 3 for reducing the friction between itself and the pipe wall, a brush 4 for cleaning the attachments on the pipe wall, and a connecting rod 5 for synchronously connecting the balls 3 and the brush 4. The lifting rod 6 is installed at the center of the upper surface of the base 1. The top of the lifting rod 6 is installed with the tensioner 2, and the top of the tensioner 2 is installed with the drill barrel 7. The balls 3 are arranged in an array at the upper and lower ends on the side of the tensioner 2. The connecting rod 5 is arranged between the upper and lower balls 3. The brush 4 is installed at the center of the connecting rod 5 and is connected to the side of the tensioner 2.

[0026] The device fits the coal dropping pipe with different pipe diameters through the tensioner 2, drills the blocked coal blocks in the coal dropping pipe by the rotation of the drill barrel 7, and at the same time relies on the contraction of the lifting rod 6 to solve the blocked layers with different thicknesses. The rolling connection between the rolling ball 3 and the pipe wall greatly reduces the wear of the tensioner 2 on the pipe wall. At the same time, as the drill barrel 7 rotates, the tensioner 2 drives the scraping brush 4 to scrape off the adhering coal blocks on the pipe wall, preventing the accumulation of fallen coal. Since the intersection of the three-way pipe on the coal dropping pipe will cause the tensioner 2 to fail to fit the pipe wall and hinder the telescopic movement of the lifting rod 6, rolling balls 3 are arranged in the upper and lower parts on the side of the tensioner 2, and the movement of the scraping brush 4 and the rolling ball 3 is synchronized through the connecting rod 5. When the upper rolling ball 3 passes through the intersection, the lower rolling ball 3 fits the pipe wall, and the connecting rod 5 restricts the displacement of the scraping brush 4 and the upper rolling ball 3. When the lower rolling ball 3 passes through the intersection after the upper rolling ball 3 passes through the intersection, the upper rolling ball 3 fits the pipe wall, and the connecting rod 5 restricts the displacement of the scraping brush 4 and the lower rolling ball 3.

[0027] See Figures 2 to 4 As shown, the rolling ball 3 is connected with a fitting joint 31 and a telescopic rod 33. Mounting holes 32 are arranged in an array on the side of the tensioner 2. The fitting joint 31 semi-surrounds the rolling ball 3, and the telescopic rod 33 is located in the mounting hole 32 and connected with the fitting joint 31.

[0028] The fitting joint 31 is used to remove the degree-of-freedom restriction of the rolling ball 3. The telescopic rod 33 is used to extend and contract the fitting joint 31 so that it can fit the pipe wall. The mounting hole 32 is used to position and install the telescopic rod 33 to prevent the diameter of the tensioner 2 from being larger than the pipe diameter of the coal dropping pipe when the telescopic rod 33 is at its minimum length.

[0029] See Figure 4 and Figure 5 As shown, a spring 332 surrounds the outside of the telescopic rod 33. One end of the spring 332 is connected to the bottom of the fitting joint 31, and the other end is connected to the bottom of the mounting hole 32. A positioning hole 331 is arranged on the side of the fitting joint 31.

[0030] When not entering the coal dropping pipe, the distance from the top of the fitting joint 31 to the center of the tensioner 2 is greater than the pipe diameter of the coal dropping pipe. The spring 332 enables the fitting joint 31 to have a certain reset ability. When the tensioner 2 enters the pipe, the fitting joint 31 is pushed towards the pipe wall by the elastic force of the spring 332 and contacts the pipe wall through the rolling ball 3.

[0031] See Figure 5 As shown, a threaded frame 43 and a plug rod 41 are arranged on the scraping brush 4. A jack 42 is arranged on the side of the tensioner 2. The threaded frame 43 is threadedly connected with the connecting rod 5. One end of the plug rod 41 is connected to the bottom of the threaded frame 43, and the other end is inserted into the jack 42.

[0032] The threaded bracket 43 is used to connect with the connecting rod 5. The insertion rod 41 is inserted into the insertion hole 42 to reinforce the connection strength of the wiper 4 on the side of the tensioner 2, preventing the wiper 4 from detaching from the tensioner 2 when the tensioner 2 rotates.

[0033] See Figures 2 to 5 As shown, a ring bracket 51 is provided at the center of the connecting rod 5, and a threaded hole 52 is provided at the center of the ring bracket 51.

[0034] The size of the ring bracket 51 needs to be larger than the size of the threaded bracket 43 on the wiper 4. The threaded hole 52 corresponds to the thread pattern on the threaded bracket 43, enabling the quick installation and disassembly of the wiper 4 by rotation, facilitating the maintenance and cleaning of the wiper 4.

[0035] See Figures 1 to 3 As shown, a motor 61 is provided at the connection between the lifting rod 6 and the tensioner 2. A housing 62 is provided at the top of the motor 61 and is rotatably connected to the tensioner 2.

[0036] The motor 61 provides power for the rotation of the drill cylinder 7 and the tensioner 2. At the same time, the housing 62 is used to prevent the direct connection between the tensioner 2 and the drill cylinder 7 and the lifting rod 6, preventing the lifting rod 6 from rotating together with the output shaft of the motor 61.

[0037] See Figures 3 to 6 As shown, a drill bit 71 and rotating blades 72 are provided on the drill cylinder 7. The drill bit 71 is installed at the top of the drill cylinder 7, and the rotating blades 72 are arranged in an array on the side of the drill cylinder 7.

[0038] The drill bit 71 is used to quickly chisel through the blocked layer. The rotating blades 72 are used to stir the blocked coal blocks after the drill cylinder 7 enters the blocked layer, facilitating the quick fall of the coal blocks. Since excessive wear of the drill bit 71 after long-term use will lead to a reduction in drilling efficiency, it is convenient to replace the drill bit 71 by separating the drill bit 71 and the drill cylinder 7 into independent components and then assembling them.

[0039] See Figure 6 As shown, a clamping strip 711 is provided on the drill bit 71, a rotating shaft 713 is installed at the bottom of the drill bit 71, and a fitting groove 712 is provided at the center of the drill cylinder 7.

[0040] The sizes of the clamping strip 711 and the fitting groove 712 correspond. The rotating shaft 713 passes through the internal centers of the tensioner 2 and the drill cylinder 7 to connect the drill bit 71 with the output shaft of the motor 61. When the motor 61 drives the rotation of the drill bit 71, the clamping strip 711 on the drill bit 71 drives the drill cylinder 7 and the tensioner 2 to rotate through the fitting groove 712.

[0041] The above embodiments only represent one or several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the appended claims.
