[0002] When installing the grain warehouse door, many different types of auxiliary assembly devices will be used. The specific types and applications of these devices may vary depending on the type, size and installation environment of the grain warehouse door. These include basic tools such as screwdrivers, wrenches, pliers, and tape measures, which are used to measure the size of the door opening to ensure that the grain truck door and the door opening match perfectly. During the installation process, sealing materials such as sealing strips and foam fillers may be used to ensure the sealing performance of the grain warehouse door, as well as personal protective equipment such as safety helmets, safety shoes, and gloves, as well as safety facilities such as safety nets and seat belts to ensure the safety of personnel during the installation process.

[0028] 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.

[0029] See also Figures 1 to 6 The present invention provides an embodiment: an auxiliary assembly device for installing a grain storage door, comprising a grain storage door 29, a grain storage door suspension fixing mechanism is arranged above the grain storage door 29, the grain storage door suspension fixing mechanism comprises a square plate 14, a circular plate 15, an electric adsorption fixing head 16, an angle adjustment mechanism and a position adjustment mechanism, the circular plate 15 is installed at the middle position of the rear end surface of the square plate 14 through a roller bearing, the electric adsorption fixing head 16 is installed at the rear end surface of the circular plate 15, and the electric adsorption fixing head 16 can be revolved around the front end of the square plate 14 and moved up and down through the position adjustment mechanism;

[0030] The circular plate 15 can be rotated and fixed by the angle adjustment mechanism.

[0031] The position adjustment mechanism includes two movable lifting bases 1, the upper end surface of the movable lifting base 1 is installed with a supporting bracket 3, the upper end surface of the supporting bracket 3 is fixedly installed on an L-shaped plate 4, the outer surface of the L-shaped plate 4 is fixedly installed on a stepper motor 5, and the output shaft of the stepper motor 5 is connected to a transmission shaft 8 through a coupling, and the outer surface of the transmission shaft 8 is fixedly sleeved with a synchronous sprocket B9; when in use, check the use of each mechanism, move the device to the working area and connect the power supply, when it is necessary to install the grain storage door 29, start the stepper motor 5 first, and the stepper motor 5 can drive the transmission shaft 8 connected thereto and the synchronous sprocket B9 fixedly sleeved on the outer surface of the transmission shaft 8 to rotate.

[0032] A connecting rod 6 is provided below the synchronous sprocket B9, and a synchronous sprocket A7 is fixedly sleeved on the outer surface of the connecting rod 6, and the synchronous sprocket A7 is connected in series with the synchronous sprocket B9 through a synchronous chain A10; when the synchronous sprocket B9 rotates, the connecting rod 6 connected in series with it through the synchronous sprocket B9 and the synchronous chain A10 will rotate along with it.

[0033] The surface of the connecting rod 6 facing the front end of the square plate 14 is fixed to the square plate 14, and a limiting square plate 28 is provided above the square plate 14. The limiting square plate 28 is arranged between the two supporting brackets 3, and the two ends of the limiting square plate 28 are respectively fixed to the two supporting brackets 3. The upper end surface of the square plate 14 is in contact with the lower end surface of the limiting square plate 28, and the shape of the front end of the square plate 14 is semi-cylindrical; when the connecting rod 6 rotates, the square plate 14 will revolve around the front end as the center. At this time, the square plate 14 is rotated clockwise around the front end of the square plate 14. When the square plate 14 rotates ninety degrees clockwise, the circular plate 15 installed in the middle position of its rear end surface and the electric adsorption fixing head 16 installed on the outer surface of the circular plate 15 will face the grain depot. The door 29 is then moved downward as a whole by the movable lifting base 1. During the downward movement of the equipment as a whole, the distance between the electric adsorption fixing head 16 and the grain storage door 29 will gradually shorten until the electric adsorption fixing head 16 contacts the grain storage door 29. Then, the grain storage door 29 and the electric adsorption fixing head 16 can be fixed to each other by the functionality of the electric adsorption fixing head 16. When the two are fixed, the equipment is lifted as a whole by the movable lifting base 1. Then, the electric adsorption fixing head 16 is rotated counterclockwise with the front end of the square plate 14 as the center by the stepper motor 5 again. When the electric adsorption fixing head 16 is rotated ninety degrees again and returns to its original position, the grain storage door 29 fixed to the outer surface of the electric adsorption fixing head 16 will become upright.

[0034] When the square plate 14 rotates counterclockwise by ninety degrees and returns to its original angle, the plane on the upper end surface of the square plate 14 will also contact the limiting square plate 28. The limiting square plate 28 can prevent the square plate 14 from continuing to rotate, thereby causing its angle to be misaligned.

[0035] The other end of the connecting rod 6 is fixedly connected to a square fixing rod 11, the cross-sectional shape of the square fixing rod 11 is square, a square sleeve 12 is provided on one side of the square fixing rod 11, the upper and lower end surfaces of the square sleeve 12 are slidably connected to the inside of the L-shaped plate 4, the square sleeve 12 is provided with a square groove 13 on the surface facing the square fixing rod 11, and the shape of the square fixing rod 11 corresponds to the shape of the inner wall of the square groove 13, and a pulling handle is fixedly installed on the outer surface of the square sleeve 12 located outside the L-shaped plate 4; when the square plate 14 is driven to rotate by the connecting rod 6, the square fixing rod 11 fixed to the outer surface of the connecting rod 6 will rotate with it At the same time, when the square plate 14 is driven by the connecting rod 6 to rotate counterclockwise for ninety degrees to return to its original angle, the square sleeve 12 can be pushed inward. As the square sleeve 12 moves at this time, the square fixing rod 11 fixed on the outer surface of the connecting rod 6 will gradually insert into the interior of the square groove 13. When the square fixing rod 11 is inserted into the interior of the square groove 13, the connecting rod 6 and the square plate 14 fixed thereto can no longer rotate. The above technical solution can fix the square plate 14 to prevent it from rotating without authorization due to the weight of the grain storage door 29, thereby causing the angle of the grain storage door 29 to change.

[0036] The angle adjustment mechanism includes an adjustment shaft A17, an inner thread groove 20 is provided on the outer side of the front end of the adjustment shaft A17, an inclined external thread sleeve 21 matching its inner thread is provided inside the internal thread groove 20, a rectangular fixing block 22 is provided on both sides of the inner side of the inclined external thread sleeve 21, the surface of the rectangular fixing block 22 facing the inner wall of the inclined external thread sleeve 21 and the surface of the inclined external thread sleeve 21 facing the rectangular fixing block 22 are both inclined surfaces, a spring 23 is connected to the surface of the rectangular fixing block 22 facing the adjustment shaft A17, and a plurality of anti-slip stripes are provided on one side of the spring 23 on the outer surface of the rectangular fixing block 22; when the grain is adjusted After the warehouse door 29 is fixed to the outer surface of the electric adsorption fixing head 16 and turned into an upright state, the inclined external thread sleeve 21 is manually rotated, and the rotating inclined external thread sleeve 21 can move inside the internal thread groove 20 through the internal thread transmission of the internal thread groove 20. At this time, the inclined external thread sleeve 21 is moved outward. With the movement of the inclined external thread sleeve 21 and the reaction force of the squeezed spring 23, the rectangular fixing block 22 can be pushed outward. When the surface of the rectangular fixing block 22 facing the adjustment shaft A17 no longer fits the surface of the adjustment shaft A17, the fixation of the adjustment shaft A17 will be released.

[0037] A manual adjustment ring 19 is fixedly sleeved on one side of the outer surface of the adjustment shaft A17, and an adjustment shaft B24 fixedly connected to the middle position of the front end surface of the circular plate 15 is provided on one side of the manual adjustment ring 19, and the adjustment shaft B24 is connected in series with the adjustment shaft A17 through a synchronous chain B18; when the fixation of the adjustment shaft A17 is released, the adjustment shaft A17 is manually rotated through the manual adjustment ring 19, and the adjustment shaft B24 connected in series with the adjustment shaft A17 through the synchronous chain B18 will rotate synchronously during the rotation of the adjustment shaft A17, and the rotating adjustment shaft B24 will drive the circular plate 15 fixed thereto and the circular plate 15 connected thereto through the electrical The grain storage door 29 connected to the dynamic adsorption fixed head 16 rotates, and the angle of the grain storage door 29 is adjusted through this structure so that its angle corresponds to the door frame where the grain storage door 29 needs to be installed. When the angle adjustment of the grain storage door 29 is completed, the inclined surface external thread sleeve 21 is rotated again, and the inclined surface external thread sleeve 21 is moved inward at this time. During the inward movement of the inclined surface external thread sleeve 21, the corresponding rectangular fixing block 22 will be pushed inward. When the surface of the rectangular fixing block 22 facing the adjustment shaft A17 is in contact with the adjustment shaft A17, the adjustment shaft A17 can be fixed. By fixing the adjustment shaft A17, the grain storage door 29 with the angle adjustment completed can be prevented from rotating without authorization.

[0038] When the rectangular fixing block 22 is pushed inward, it will squeeze the spring 23 connected to it. Through the reaction force of the squeezed spring 23, the rectangular fixing block 22 can be pushed outward during the process of moving the inclined external threaded sleeve 21 outward, thereby releasing the fixation between the rectangular fixing block 22 and the adjustment shaft A17.

[0039] A cylinder base 25 fixedly mounted on the outer surface of the square plate 14 is provided on the upper and lower sides of the adjustment shaft B24, and one side of the outer surface of the cylinder base 25 is fixedly mounted on a horizontal rod cylinder 26, and the piston rod of the horizontal rod cylinder 26 is connected with an angle adjustment push rod 27; when the angle adjustment of the granary door 29 is completed, the angle adjustment push rod 27 is pushed backward by the horizontal rod cylinder 26, and as the angle adjustment push rod 27 moves, the angle adjustment push rod 27 will contact the front end surface of the granary door 29, when the angle adjustment push rod 27 located above the square plate 14 contacts the granary door 29, but is still pushing the angle adjustment push rod 27 backward, at this time, the granary door The top end of the granary door 29 will tilt backward accordingly. If the angle adjustment push rod 27 located below the square plate 14 contacts the granary door 29 but is still being pushed backward, the top end of the granary door 29 will tilt forward accordingly. When installing the granary door 29, the two angle adjustment push rods 27 are simultaneously moved backward until the two angle adjustment push rods 27 contact the granary door 29 to prevent it from tilting. The above technical solution can be used to adjust the inclination angle of the granary door 29 to prevent the granary door 29 from tilting during the installation of the granary door 29, thereby preventing the granary door 29 from tilting and requiring manual adjustment.

[0040] When the angle adjustment of the grain storage door 29 is completed, its height is adjusted by the movable lifting base 1, and the grain storage door 29 can be inserted into the interior of the door frame by the universal wheel moving device installed on the lower end surface of the movable lifting base 1. After that, the installer can fix the grain storage door 29 in this case. Through the above technical solution, the installation process of the grain storage door 29 no longer needs to be manually lifted to the interior of the installation frame, thereby reducing the energy required during the installation process and increasing its safety.

[0041] The outer side of the circular plate 15 is provided with an anti-rust liquid spraying mechanism 2, which includes an annular metal shell 201, an anti-rust liquid delivery pipe 202, an anti-rust liquid annular receiving groove 203, a roller bearing ring 204, four spray heads 205 and a rotating mechanism. The anti-rust liquid annular receiving groove 203 is located inside the annular metal shell 201, the anti-rust liquid delivery pipe 202 is connected to the upper side of the front end surface of the annular metal shell 201, and the interior of the anti-rust liquid delivery pipe 202 is communicated with the interior of the anti-rust liquid annular receiving groove 203;

[0042] The roller bearing ring 204 is installed on the rear end face of the annular metal shell 201 through a roller bearing, and four spray heads 205 are fixedly installed on the four end corners of the rear end face of the roller bearing ring 204, and the interior of the spray head 205 is also communicated with the interior of the anti-rust liquid annular storage groove 203, and the roller bearing ring 204 can be rotated by a rotating mechanism; the rotating mechanism includes a rotating motor 208, and the output shaft of the rotating motor 208 is connected to a rotating shaft 209 through a coupling, and a small gear 207 is fixedly sleeved on the outer surface of the rotating shaft 209, and the small gear 207 is meshed with an inner gear ring 206 fixed to the inner wall of the roller bearing ring 204; when the grain storage door 29 is installed, the device is moved outward as a whole, and then the rotating motor 208 drives the rotating shaft 209 connected thereto and the fixed sleeve arranged on the rotating shaft The small gear 207 on the outer surface of the shaft 209 rotates, and the rotating small gear 207 can drive the inner gear ring 206 meshing therewith and the roller bearing ring 204 fixed to the inner gear ring 206 to rotate. When the roller bearing ring 204 rotates, the spray head 205 installed on the rear end surface of the roller bearing ring 204 will revolve around the electric adsorption fixing head 16. During the rotation process, the spray head 205 sprays the anti-rust liquid input into the anti-rust liquid annular storage groove 203 through the anti-rust liquid delivery pipe 202 through its own function. The spray head 205 that sprays the anti-rust liquid while revolving can automatically spray a layer of anti-rust liquid on the outer surface of the installed grain storage door 29, thereby improving the environmental resistance of the grain storage door 29. The above technical solution improves the convenience of spraying the anti-rust liquid.

[0043] If the area of ​​the grain storage door 29 is large and the rotating spray head 205 cannot spray to the middle position inside the grain storage door 29, the height of the movable lifting base 1 can be adjusted to change the spraying range, thereby ensuring that the anti-rust liquid sprayed by the spray head 205 can be sprayed to the middle position of the outer surface of the rotating shaft 209. If it cannot be sprayed to the edges on both sides of the rotating shaft 209, it is necessary to push the entire equipment back and forth through the universal pulley installed on the lower end surface of the movable lifting base 1.
