[0002] Pipeline transportation has spread to the power, metallurgy, coal, petroleum, chemical industry, building materials, machinery and other industries, and is developing at a high speed. The wear of the pipe has always been a factor affecting safe and civilized production. With the continuous development of science and technology, materials are also constantly innovating, and cast stone, cast steel, alloy, adhesive ceramics and other materials have appeared one after another. When transporting grain, pipes are often used to transport bulk grains such as corn, rice, and wheat. In order to improve the wear resistance of the pipe and extend its service life, a layer of polyurethane lining is usually poured on the inner wall of the pipe.

[0003] However, the existing equipment for pouring polyurethane lining on the inner wall of the chute is rarely able to evenly add material to the inner wall of the chute while controlling the chute body to rotate at high speed, so that the polyurethane material is fully and evenly thrown onto its inner wall under the action of centrifugal force, resulting in uneven thickness of the polyurethane lining and low efficiency of the pouring work. In this regard, we propose an equipment for pouring polyurethane lining on the inner wall of the chute and a method for using the same. Summary of the invention

[0007] A feeding pipe passes horizontally through the hollow driven shaft from left to right, and the right end of the feeding pipe extends into the interior of the chute body. A casting machine is installed at the left end of the feeding pipe, and a casting hose is connected to the output end of the casting machine. A mounting groove adapted to the casting hose is provided in the feeding pipe, and the casting hose is placed in the mounting groove. The output end of the casting hose is flush with one end of the feeding pipe extending into the interior of the chute body, and a discharge port is provided at the output end of the casting hose. The casting machine conveys the polyurethane casting material into the chute body through the casting hose and the feeding pipe.

[0009] While the rotating motor drives the slide pipe body to rotate at high speed, the feeding pipe moves left and right to evenly feed the polyurethane material to be poured into the slide pipe body. Under the centrifugal force generated by the high-speed rotation of the slide pipe body, the polyurethane material is evenly and comprehensively thrown onto the inner wall of the slide pipe body.

[0015] Preferably, the fixing frame locks and fixes the feeding pipe via a clamp.

[0016] Compared with the prior art, the beneficial effects of the device of the present invention are:

[0017] The semi-automatic operation is realized by adopting a rotary motor, a forward and reverse motor and a pouring machine, which not only improves the efficiency and quality of the pouring of the polyurethane lining, but also makes it safer. The forward and reverse motor controls the meshing of the rack and the gear to realize the uniform left and right movement of the feeding pipe. When the feeding pipe moves left and right to evenly feed the polyurethane material to be poured into the slide pipe body, the centrifugal force generated by the rotation of the slide pipe body is used to evenly and comprehensively throw the polyurethane material onto the inner wall of the slide pipe body to avoid uneven thickness. The position of the second flange can be adjusted as the hollow driven shaft moves left and right, so that the first flange and the second flange can be matched to fix the slide pipe bodies of different lengths within the length range of the oven, thereby improving the applicability of the entire device.

[0018] A method for using a device for pouring a polyurethane lining on the inner wall of a slide pipe comprises the following steps:

[0019] (A) First push the oven door to the right to open it. At the same time, the slider slides to the right along the sealing slide groove, then lift the slide body and slowly put it into the oven, so that the limiting holes on the disc bodies at the left and right ends of the slide body are aligned with the limiting screws on the second flange and the first flange respectively, and the limiting screws are inserted into the limiting holes, which can play a basic role in fixing the slide body. It is better to ensure that the horizontal center section of the slide body is on the same horizontal plane as the horizontal center sections of the first flange and the second flange, so as to achieve rapid and accurate positioning of the slide body;

[0020] (B) Then use bolts to connect the right end of the slide pipe body to the first flange. Since the first flange is closed, the right end of the slide pipe body is closed; similarly, use the second flange and bolts to connect the left end of the slide pipe body to the right end of the hollow driven shaft. Since the center of the second flange is provided with a through hole for the feed pipe to move in and out left and right, the left end of the slide pipe body is connected to the right end of the hollow driven shaft. After the slide pipe body is fixed, push the box door to the left to close it;

[0021] (C) A first rotating bearing is installed on the driving shaft, and the first rotating bearing is assembled into a first bearing seat of the first supporting platform. Similarly, a second rotating bearing is installed on the hollow driven shaft, and the second rotating bearing is assembled into a second bearing seat of the second supporting platform. The output end of the rotating motor is connected to the driving shaft to provide power for the slide body to rotate and provide conditions for realizing its rotation;

[0022] (D) At this time, use the clamp to fix the feed pipe on the fixed frame, connect one end of the pouring hose to the pouring hose, and after the connection, place the pouring hose part into the installation groove, ensuring that the other end of the pouring hose is flush with the end of the feed pipe extending into the inside of the slide pipe body;

[0023] (E) Then start the rotating motor, forward and reverse motor and pouring machine at the same time. The pouring machine feeds the polyurethane material into the chute body through the pouring hose and the feeding pipe. The chute body rotates at high speed under the action of the rotating motor. At the same time, the forward and reverse motor drives the gear to rotate forward and reverse. The rack and the gear are engaged to drive the fixed frame and the feeding pipe fixed on it to move left and right at a uniform speed. When the feeding pipe moves left and right at a uniform speed in the chute body, the polyurethane material is evenly fed into the chute body. The centrifugal force of the chute body is used to evenly and comprehensively throw the polyurethane material onto the inner wall of the chute body to complete the pouring.

[0024] Preferably, before the feed pipe is installed and fixed, its length needs to be measured to select one that matches the length of the slide pipe body.

[0025] Preferably, the horizontal center sections of the slide pipe body, the driving shaft, the hollow driven shaft and the feeding pipe are all ensured to be on the same horizontal plane.

[0026] Compared with the prior art, the beneficial effects of the method of use of the present invention are:

[0027] The horizontal center sections of the slide tube body, driving shaft, hollow driven shaft and feeding tube must all be on the same level, which can ensure that the entire device is evenly stressed and more stable when the slide tube body rotates at high speed; the limit screws and limit holes are used in conjunction to facilitate the fast and accurate positioning of the slide tube body during installation, saving manual alignment time and lifting time, saving time and effort.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] See also Figures 1 to 5 , the present invention provides an embodiment: a device for pouring polyurethane lining on the inner wall of a slide pipe, comprising an oven 1, a base 2 is provided at the bottom of the oven 1, and a slide pipe body 3 is installed at the horizontal center position inside the oven 1, the right end of the slide pipe body 3 is connected to a driving shaft 6 through a first flange 4, and the right end of the driving shaft 6 passes through a through hole on the right side wall of the oven 1 and extends out of the box to be connected to a rotating motor 8, a first support platform 7 is installed on the right side of the oven 1, and a first bearing seat 701 is provided on the first support platform 7, and a first rotating bearing 601 adapted to the first bearing seat 701 for realizing rotation is sleeved on the outer wall of the driving shaft 6;

[0036] The left end of the slide pipe body 3 is connected to a hollow driven shaft 9 through a second flange 5, and the left end of the hollow driven shaft 9 passes through a through hole on the left wall of the oven 1 and extends out of the oven. A second rotating bearing 901 is sleeved on the outer wall of the left end of the hollow driven shaft 9. A second support platform 10 is installed on the left side of the oven 1, and a second bearing seat 1001 matched with the second rotating bearing 901 is arranged on the second support platform 10;

[0037] A feeding pipe 11 passes horizontally through the hollow driven shaft 9 from left to right, and the right end of the feeding pipe 11 extends into the interior of the chute body 3. A casting machine 12 is installed at the left end of the feeding pipe 11, and a casting hose 13 is connected to the output end of the casting machine 12. A mounting groove 1301 adapted to the casting hose 13 is provided in the feeding pipe 11. The casting hose 13 is placed in the mounting groove 1301. The output end of the casting hose 13 is flush with one end of the feeding pipe 11 extending into the interior of the chute body 3, and a discharge port 1302 is provided at the output end of the casting hose 13. The casting machine 12 transports the polyurethane casting material into the chute body 3 through the casting hose 13 and the feeding pipe 11.

[0038] A support frame 14 is installed at the bottom of the feeding tube 11, and a horizontally placed rack 15 is connected to the bottom of the fixed frame 14. A gear 16 meshing with the rack 15 is provided at the bottom of the rack 15, and a forward and reverse motor 17 is connected to the gear 16. The forward and reverse motor 17 can control and change the transportation direction of the rack 15 by forward and reverse rotation, thereby controlling the feeding tube 11 to move left and right at a uniform speed;

[0039] While the rotating motor 8 drives the slide pipe body 3 to rotate at high speed, the feeding pipe 11 moves left and right to evenly feed the polyurethane material to be poured into the slide pipe body 3. Under the action of the centrifugal force generated by the high-speed rotation of the slide pipe body 3, the polyurethane material is evenly and comprehensively thrown onto the inner wall of the slide pipe body 3. The rotating motor 8, the forward and reverse motor 17 and the pouring machine 12 are used to achieve semi-automation, which not only improves the efficiency and quality of pouring the polyurethane lining, but also makes it safer. The forward and reverse motor 17 controls the meshing of the rack 15 and the gear 16 to realize the uniform movement of the feeding pipe 11 left and right. While the feeding pipe 11 moves left and right to evenly feed the polyurethane material to be poured into the slide pipe body 3, the centrifugal force generated by the rotation of the slide pipe body 3 is used to evenly and comprehensively throw the polyurethane material onto the inner wall of the slide pipe body 3 to avoid uneven thickness.

[0040] Furthermore, the top surface of the oven 1 is slidably connected to a box door 18, and sliders 1801 are installed on both side walls of the box door 18. Sealing grooves 101 are provided in the top side walls of the oven 1 at positions corresponding to the positions of the sliders 1801, and the sizes of the sealing grooves 101 and the sliders 1801 match. A visual window 1802 is provided on the box door 18. The sealing grooves 101 are used in conjunction with the sliders 1801 to facilitate the opening and closing of the box door 18, saving time and effort, and can play a certain sealing role, thereby reducing the loss of heat in the oven 1 and saving energy. The visual window 1802 is convenient for checking the condition of the oven 1 at any time.

[0041] Furthermore, limiting screws 19 for positioning are provided on the first flange 4 and the second flange 5 in the oven 1, and limiting holes 1901 are provided on the disc bodies at both ends of the slide pipe body 3 at positions corresponding to the limiting screws 19, and the limiting holes 1901 are adapted to the limiting screws 19. The limiting screws 19 and the limiting holes 1901 are used together to facilitate the rapid and accurate positioning of the slide pipe body 3 during installation, saving the time for manual alignment and lifting, saving time and effort.

[0042] Furthermore, the position of the second flange 5 can be adjusted as the hollow driven shaft 9 moves left and right, so that the first flange 4 and the second flange 5 can cooperate to fix the slide pipe body 3 of different lengths within the length range of the oven 1, thereby improving the applicability of the entire device.

[0043] Furthermore, the first flange 4 is closed, and a through hole is provided at the center of the second flange 5 for the feeding pipe 11 to move in and out left and right. The first flange 4 is closed to prevent the polyurethane material from being thrown out from the end of the chute body 3 close to the first flange 4 under high-speed centrifugation, causing waste of the polyurethane material.

[0044] Furthermore, the pouring hose 13 forms a snap-fit ​​detachable structure with the feeding pipe 11 through the installation groove 1301, and the local inner wall of the installation groove 1301 is tightly fitted with the local outer wall of the pouring hose 13, which is convenient for the installation, disassembly, replacement and cleaning of the pouring hose 13. If the feeding pipe 11 is used directly for feeding, it is easy to cause a large amount of polyurethane material to remain in the feeding pipe 11, affecting the amount of polyurethane material fed into the slide pipe body 3, thereby affecting the pouring result, and it is also inconvenient to clean the feeding pipe 11.

[0045] Furthermore, the fixing frame 14 locks and fixes the feeding pipe 11 through the clamp 1401, so as to facilitate the installation, removal and replacement of the feeding pipe 11.

[0046] A method for using a device for pouring a polyurethane lining on the inner wall of a slide pipe comprises the following steps:

[0047] (A) First, push the oven door 18 to the right to open it. At the same time, the slider 1801 slides to the right along the sealing slide groove 101, and then lift the slide pipe body 3 and slowly put it into the oven 1, so that the limiting holes 1901 on the disc bodies at the left and right ends of the slide pipe body 3 are respectively aligned with the limiting screws 19 on the second flange 5 and the first flange 4 for engagement. The limiting screws 19 are inserted into the limiting holes 1901, which can play a basic role in fixing the slide pipe body 3. It is better to ensure that the horizontal center section of the slide pipe body 3 is on the same horizontal plane as the horizontal center sections of the first flange 4 and the second flange 5, so as to achieve rapid and accurate positioning of the slide pipe body 3;

[0048] (B) Then, the right end of the slide pipe body 3 is connected to the first flange 4 by bolts. Since the first flange 4 is closed, the right end of the slide pipe body 3 is closed. Similarly, the left end of the slide pipe body 3 is connected to the right end of the hollow driven shaft 9 by the second flange 5 and bolts. Since a through hole for the feeding pipe 11 to move in and out left and right is opened at the center of the second flange 5, the left end of the slide pipe body 3 is connected to the right end of the hollow driven shaft 9. After the slide pipe body 3 is fixed, push the box door 18 to the left to close it.

[0049] (C) A first rotating bearing 601 is installed on the driving shaft 6, and the first rotating bearing 601 is assembled into a first bearing seat 701 of the first supporting platform 7. Similarly, a second rotating bearing 901 is installed on the hollow driven shaft 9, and the second rotating bearing 901 is assembled into a second bearing seat 1001 of the second supporting platform 10. The output end of the rotating motor 8 is connected to the driving shaft 6, giving the slide tube body 3 a power to rotate and providing conditions for realizing its rotation;

[0050] (D) At this time, the feeding pipe 11 is fixed to the fixing frame 14 by using the clamp 1401, and one end of the pouring hose 13 is connected to the pouring hose 13. After the connection is completed, the pouring hose 13 is partially placed into the installation groove 1301, and it is ensured that the other end of the pouring hose 13 is flush with the end of the feeding pipe 11 extending into the interior of the slide pipe body 3;

[0051] (E) Then, the rotating motor 8, the forward and reverse motor 17 and the pouring machine 12 are turned on at the same time. The pouring machine 12 feeds the polyurethane material into the chute body 3 through the pouring hose 13 and the feeding pipe 11. The chute body 3 rotates at a high speed under the action of the rotating motor 8. At the same time, the forward and reverse motor 17 drives the gear 16 to rotate forward and reverse. The rack 15 is engaged with the gear 16 to drive the fixed frame 14 and the feeding pipe 11 fixed thereon to move left and right at a uniform speed. When the feeding pipe 11 moves left and right at a uniform speed in the chute body 3, the polyurethane material is evenly fed into the chute body 3. The centrifugal force of the chute body 3 is used to evenly and comprehensively throw the polyurethane material onto the inner wall of the chute body 3 to complete the pouring.

[0052] Furthermore, before the feed pipe 11 is installed and fixed, its length needs to be measured and the one that matches the length of the slide pipe body 3 is selected to ensure that the feed pipe 11 enters the slide pipe body 3 to a sufficient extent.

[0053] Furthermore, the horizontal center sections of the slide tube body 3, the driving shaft 6, the hollow driven shaft 9 and the feeding tube 11 must all be ensured to be on the same horizontal plane, which can ensure that the entire device is evenly stressed and more stable when the slide tube body 3 rotates at high speed.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

Similarly, the left end of the slide pipe body (3) is connected to the right end of the hollow driven shaft (9) by the second flange (5) and bolts. Since a through hole for the feeding pipe (11) to move in and out left and right is opened at the center of the second flange (5), the left end of the slide pipe body (3) is connected to the right end of the hollow driven shaft (9). After the slide pipe body (3) is fixed, the box door (18) is pushed to the left to close it. (C) A first rotating bearing (601) is installed on the driving shaft (6), and the first rotating bearing (601) is assembled into a first bearing seat (701) of the first support platform (7). Similarly, a second rotating bearing (901) is installed on the hollow driven shaft (9), and the second rotating bearing (901) is assembled into a second bearing seat (1001) of the second support platform (10). The output end of the rotating motor (8) is connected to the driving shaft (6), so as to provide power for the slide tube body (3) to rotate and provide conditions for realizing its rotation. (D) At this time, the feeding pipe (11) is fixed to the fixing frame (14) by using the clamp (1401), and one end of the pouring hose (13) is connected to the pouring hose (13). After the connection is completed, the pouring hose (13) is partially placed into the installation groove (1301), ensuring that the other end of the pouring hose (13) is flush with the end of the feeding pipe (11) extending into the interior of the slide pipe body (3); (E) Then, the rotating motor (8), the forward and reverse motor (17) and the pouring machine (12) are turned on simultaneously. The pouring machine (12) feeds the polyurethane material into the chute body (3) through the pouring hose (13) and the feeding pipe (11). The chute body (3) rotates at a high speed under the action of the rotating motor (8). At the same time, the forward and reverse motor (17) drives the gear (16) to rotate forward and reverse. The rack (15) meshes with the gear (16) to drive the fixed frame (14) and the feeding pipe (11) fixed thereon to move left and right at a uniform speed. When the feeding pipe (11) moves left and right at a uniform speed in the chute body (3), the polyurethane material is evenly fed into the chute body (3). The centrifugal force of the chute body (3) is utilized to evenly and comprehensively throw the polyurethane material onto the inner wall of the chute body (3), thereby completing the pouring.

2. The method for using the device for pouring polyurethane lining on the inner wall of a slide pipe according to claim 1, characterized in that: Before the feed pipe (11) is installed and fixed, its length needs to be measured to select one that matches the length of the slide pipe body (3).

3. The method for using the device for pouring polyurethane lining on the inner wall of a slide pipe according to claim 1, characterized in that: The horizontal center sections of the slide pipe body (3), the driving shaft (6), the hollow driven shaft (9) and the feeding pipe (11) are all ensured to be on the same horizontal plane.
