[0002] After long-term operation, the granulation production line needs to conduct regular inspection and maintenance of related equipment. Among them, the screw disassembly and maintenance are often involved. In the actual disassembly process, there are often a certain number of screws that need to be disassembled and maintained at the same time. However, since the length of a single screw is about 4 meters, the weight exceeds 200 kilograms, and the inner wall of the screw and the screw barrel is full of raw materials, the resistance to disassembly and pulling out becomes greater, making the entire disassembly process particularly difficult.

[0003] In the prior art, a hook is usually used to pull the screw out of the relevant equipment. In order to prevent the hook from loosening, it is often necessary to assign multiple workers to stand in the middle of the screw to hold the hook. This process is not only time-consuming, but also requires multiple adjustments and replacements of the hook during the disassembly process. In addition, in the absence of any protective measures under the screw, there is a risk of the workers being injured by the falling screw.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

[0023] The present application embodiment provides a Figure 1 The screw loading and unloading device 100 shown in the figure comprises a base 11, an adjustment frame 12, a locking mechanism 13 and a driving mechanism 14. The adjustment frame 12 is fixedly connected to the top of the base 11, and the base 11 and the adjustment frame 12 are arranged in the same length direction and width direction. A slide rail 121 extending along the length direction of the screw is fixedly installed on the adjustment frame 12, and the length direction of the slide rail 121 is arranged along the length direction of the adjustment frame 12. The locking mechanism 13 is slidably connected to the slide rail 121. The locking mechanism 13 comprises at least one screw clamp 131 for clamping the screw, and the screw clamp 131 can clamp at least one screw at the same time. The driving mechanism 14 is connected to the locking mechanism 13, and the driving mechanism 14 can drive the locking mechanism 13 to reciprocate along the track specified by the slide rail 121. In this embodiment, the base 11 and the adjustment frame 12 are rectangular or rectangular frame structures, and the specific size and material can be adjusted according to actual conditions.

[0024] When removing the screw, the screw loading and unloading device 100 can be moved to the screw mouth of the equipment to be disassembled and fixed, and then the locking mechanism 13 can be moved along the slide rail 121 to the side close to the screw mouth, and the end of the screw to be disassembled can be clamped and fixed by the screw clamp 131, and under the drive of the driving mechanism 14, the screw clamp 131 can be moved along the slide rail 121 in the direction away from the equipment to be disassembled, so as to pull out the screw; when installing the screw, the screw to be installed can be placed on the screw loading and unloading device 100, and then the screw loading and unloading device 100 can be moved to the screw mouth of the equipment to be installed, and the locking mechanism 13 can be moved along the slide rail 121 to the side away from the equipment to be installed, and the screw can be clamped by the screw clamp 131, and under the drive of the driving mechanism 14, the screw clamp 131 can be clamped and moved along the slide rail 121 in the direction close to the screw mouth, so as to insert the screw into the screw barrel of the equipment to be installed. Semi-automatic loading and unloading of screws is performed by using the screw loading and unloading device 100, which greatly reduces the labor cost of the staff; the use of the screw loading and unloading device 100 is simple and convenient, and improves the disassembly and installation efficiency of the screw. If the screw to be removed is longer, the locking mechanism 13 can clamp the end of the screw and move it along the slide rail 121 in a direction away from the screw mouth to the end of the slide rail 121, then cancel the clamping limit of the screw by the screw clamp 131, and move the screw clamp 131 back to the screw mouth of the equipment to be removed, repeat the above operation, clamp the screw and pull it out again, thereby realizing the disassembly operation of the longer screw; if the screw to be installed is longer, the locking mechanism 13 can clamp the screw and move it along the slide rail 121 in a direction close to the screw mouth to the end of the slide rail 121, then cancel the clamping limit of the screw by the screw clamp 131, and move the screw clamp 131 back to the end of the side of the slide rail 121 away from the screw mouth, repeat the above operation, clamp the screw and push it forward again, thereby realizing the installation operation of the longer screw. Through the above manner, the installation and removal of a long screw can be achieved when the screw loading and unloading device 100 has a small outer size, thereby reducing the space occupied by the screw loading and unloading device 100 and increasing the practicality of the screw loading and unloading device 100.

[0025] As an optional implementation, Figure 2As shown, the locking mechanism 13 also includes a moving block 132, which is slidably connected to the slide rail 121, and the screw clamp 131 can be detachably connected to the moving block 132 by bolt connection or other methods. After the screw loading and unloading device 100 has been used for a period of time, the screw clamp 131 may need to be maintained or replaced. When loading and unloading screws of different specifications, the screw clamp 131 may also need to be adjusted or replaced. During disassembly, the screw clamp 131 can be disassembled by separating the screw clamp 131 from the moving block 132. At the same time, compared with directly slidingly connecting the screw clamp 131 to the slide rail 121, the method in which the screw clamp 131 is slidably connected to the slide rail 121 through the moving block 132 does not require the moving block 132 to be separated from the slide rail 121 during disassembly, making the disassembly and installation of the screw clamp 131 more convenient.

[0026] As an optional implementation, Figure 2 As shown, the screw clamp 131 includes a clamp arm 1311 capable of clamping at least two screws, so that the screw loading and unloading device 100 can load and unload multiple screws at the same time. In this embodiment, the screw clamp 131 is provided with two clamp arms 1311 rotatably connected to each other and a fastener 1312 for limiting the rotation of each clamp arm 1311. Specifically, the two clamp arms 1311 are arranged up and down, wherein the clamp arm 1311 located at the bottom is connected to the upper surface of the moving block 132, and the clamp arm 1311 located at the top is rotatably connected to the clamp arm 1311 at the bottom, and both are hinged at one end along the length direction of themselves; at the same time, the fastener 1312 is located at the other end of the hinge of the two clamp arms 1311 along the length direction, and the fastener 1312 can be a bolt or the like to limit the rotation between the two clamp arms 1311. The two clamping arms 1311 can be rotated to abut between adjacent threads of the screw rod for clamping, and then the two clamping arms 1311 are limited and fixed by the fasteners 1312, so that the screw rod clamp 131 can clamp the screw rod firmly and stably.

[0027] As an optional implementation, Figure 2 As shown, at least one notch 1313 is provided on one side of each clamp arm 1311 abutting against the screw rod. When the screw rod clamp 131 clamps the screw rod, the screw rod is clamped into the notch 1313 of the clamp arm 1311. Multiple notches 1313 can be provided on the clamp arm 1311. When the upper and lower clamp arms 1311 cooperate with each other to clamp the screw rod, the two corresponding notches 1313 above and below can clamp a screw rod, so that the screw rod loading and unloading device 100 can realize the disassembly and installation of multiple screw rods. The notch 1313 includes at least one of an arc-shaped notch, a semi-regular polygonal notch or an irregular notch. The notch 1313 of a suitable shape can be selected according to the actual clamping requirements to realize the fastening and clamping of screw rods of different shapes and specifications. In this embodiment, the notch 1313 on the clamp arm 1311 is an arc-shaped notch.

[0028] As an optional implementation, Figure 2 As shown, the locking mechanism 13 also includes an angle adjustment member 133 for adjusting the angle of the screw clamp 131, one end of the angle adjustment member 133 is connected to the clamp arm 1311 located below, and the other end of the angle adjustment member 133 is connected to the moving block 132. For different screw loading and unloading conditions, the helix angle and rotation direction of the screw involved may be different. The angle adjustment member 131 can adjust the clamping angle of the screw clamp 131, so that the adjustment angle of the screw clamp 131 corresponds to the helix angle and rotation direction of the screw, thereby enhancing the overall applicability of the device.

[0029] As an optional implementation, Figure 3 As shown, the screw loading and unloading device 100 also includes a support mechanism 15 for lifting the screw, and the support mechanism 15 includes a telescopic frame 151 and a support member 152. The telescopic frame 151 is fixedly connected to the adjustment frame 12 along the length direction of the slide rail 121, and the support member 152 is connected to the end of the telescopic frame 151 away from the adjustment frame 12. In this embodiment, the support member 152 can be a support roller, which is rotatably connected to the telescopic frame 151. When the length of the screw to be disassembled or installed is long, the length of the screw may exceed the length of the adjustment frame 12. The support member 152 can lift the part of the screw that exceeds the adjustment frame 12 to prevent the excess weight of the screw from causing the entire device to tilt or the screw to fall. At the same time, the support mechanism 15 is installed to the adjustment frame 12 in a telescopic or foldable manner. When the support mechanism 15 is not in use, the support mechanism 15 can be retracted or folded to reduce the size and occupied space of the screw loading and unloading device 100.

[0030] As an optional implementation, Figure 3 As shown, the screw loading and unloading device 100 also includes a lifting mechanism 16, which is installed between the base 11 and the adjustment frame 12 along the height direction of the base 11. The lifting mechanism 16 is used to adjust the height of the adjustment frame 12. In this embodiment, the lifting mechanism 16 is selected as a plurality of lifting screw rods, and is respectively installed at the geometrically symmetrical points of the adjustment frame 12, so as to achieve the role of sharing the load-bearing and further enhance the stability of the device. By adjusting the height of the adjustment frame 12, the locking mechanism 13 and the screw are at the same height, which facilitates the subsequent clamping and loading and unloading of the screw, so that the screw loading and unloading device 100 can be adapted to a variety of equipment.

[0031] As an optional implementation, Figure 3As shown, the driving mechanism 14 includes a first driving member 141 for mainly providing power and at least one second driving member 142 for auxiliary power, and the first driving member 141 is installed on the base 11 and each second driving member 142 is installed on the frame of the base 11. In this embodiment, the first driving member 141 adopts a worm gear mechanism, and the second driving member 142 is two cylinders. The first driving member 141 is located in the frame of the base 11, and each second driving member 142 is located on both sides along the length direction of the base 11, and the two second driving members 142 are correspondingly installed on both sides of the upper slide rail 121. When the screw is initially disassembled, due to the large amount of raw materials between the screw and the screw barrel where it is located, the resistance encountered when pulling out the screw is increased, especially when multiple screws need to be disassembled at the same time, only one driving member may not be able to provide sufficient power, resulting in the situation where the screw cannot be disassembled smoothly. Therefore, in addition to the first driving member 141, two second driving members 142 are also provided in the embodiment of the present application. The first driving member 141 provides power throughout the entire process of disassembly or installation, and the second driving member 142 is used to assist the first driving member 141 in providing power when the first driving member 141 is insufficiently powered, especially at the beginning of the disassembly process or when multiple screws need to be disassembled at the same time, the first driving member 141 cannot provide sufficient power. The second driving member 142 can assist the first driving member 141 in providing power to jointly complete the disassembly operation of the screws.

[0032] As an optional implementation, Figure 3 As shown, the driving mechanism 14 further includes a first transmission member 143 and at least one second transmission member 144. The first driving member 141 is connected to the locking mechanism 13 through the first transmission member 143, and the second driving member 142 is detachably connected to the locking mechanism 13 through the second transmission member 144. Specifically, both the first transmission member 143 and the second transmission member 144 are connected to the moving block 132. In this embodiment, the first transmission member 143 can be a steering machine to convert the driving force of the first driving member 141 vertically installed in the frame of the base 11 into a driving force in the horizontal direction along the slide rail 121. The second transmission member 144 can be a connecting rod, and the indirect connection relationship between the second driving member 142 on both sides of the slide rail 121 and the two sides of the moving block 132 is realized through the connecting rod. However, it should be noted that when the length of the screw being loaded and unloaded is too long, in the initial stage of extraction or insertion, it is necessary to drive through the first and second driving members corresponding to the first and second transmission members; when in the middle of loading and unloading, the staff is required to manually cancel the indirect connection relationship between the second transmission member 144 and the moving block 132 to prevent the second transmission member 144 from interfering with the loading and unloading process. At the same time, after a part of the screw is pulled out, the friction between the screw and the screw barrel is reduced, and the connection between the second transmission member 144 and the moving block 132 can be canceled, and only the first driving member 141 is used to provide power, ensuring that the drive mechanism 14 can save energy and avoid waste of resources while providing sufficient power.

[0033] As an optional implementation, Figure 3 As shown, the screw loading and unloading device 100 also includes a fixing mechanism 17 for fixing the position of the adjustment frame 12, and the fixing mechanism 17 is fixedly connected to one end of the adjustment frame 12 away from the support mechanism 15 along the length direction. The fixing mechanism 17 can fix the position of the screw loading and unloading device 100 to prevent the screw loading and unloading device 100 from being relatively displaced with related equipment during disassembly or installation. Specifically, the fixing mechanism 17 can be detachably connected to the equipment to be disassembled or installed with the screw by bolt connection.

[0034] As an optional implementation, Figure 3 As shown, a roller 18 or a universal wheel is also installed at the bottom of the base 11. The roller 18 can make the movement of the screw loading and unloading device 100 more convenient, thereby facilitating the adjustment of the position of the screw loading and unloading device 100 and further improving the convenience of the device.

[0035] As an optional implementation, Figure 4 As shown, the screw loading and unloading device 100 further includes a control mechanism 19, which is electrically connected to the first driving member 141 and the second driving member 142. The control mechanism 19 can more accurately and quickly control the first driving member 141 and the second driving member 142, thereby improving the automation of the device.
