[0002] The filter press uses a special filter medium to apply a certain pressure to the object, so that the liquid is dialyzed out. It is a kind of mechanical equipment, which is a commonly used solid-liquid separation equipment. It has been used in chemical production since the early 18th century, and is still widely used in chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramic and environmental protection industries. When using it, it is usually necessary to install a frame at the bottom to obtain better stability. The frame of the filter press is heavy, and the existing technology generally requires the use of a hoist with a winch for auxiliary installation; According to a Chinese patent with application number 202310298462.5, a tool for a large roughing mill frame is disclosed. During hoisting, two hoisting tool beams can support the upper and lower surfaces of the roughing mill frame, and two intermediate support seats can support the side and top surfaces of the intermediate groove of the roughing mill frame, so that the hoisting tool can firmly buckle the roughing mill frame. During the hoisting process, the roughing mill frame will not shake, which is convenient for hoisting heavy roughing mill frames. The hoisting tool is in direct contact with the roughing mill frame, which can greatly reduce the height requirement for the crane in the factory building, and can also carry out hoisting operations in factories with limited space; Nevertheless, during the use of the above-mentioned tools for large rough rolling mill frames, it is necessary to frequently install and disassemble the brackets, which affects the efficiency of lifting.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 12 The technical solution provided by the present invention specifically includes the following embodiments: An auxiliary device for installing a filter press frame comprises a hoisting part 100, a coarse adjustment part 200, a grabbing hook part 300 and a lateral positioning part 400. The coarse adjustment part 200 is located at the bottom of the hoisting part 100. There are two coarse adjustment parts 200, which are distributed at the left and right ends of the hoisting part 100. The coarse adjustment part 200 is used for coarse adjustment. The grabbing hook parts 300 are distributed at the front and rear ends of the coarse adjustment part 200. The grabbing hook parts 300 are used for hoisting the filter press frame. The lateral positioning part 400 is fixed at the bottom of the coarse adjustment part 200. The lateral positioning part 400 is used for left and right positioning of the filter press frame.

[0020] For further details, please refer to Figure 1 , Figure 2 As shown: The hoisting part 100 includes an end plate 101, a suspension rod 102, a sleeve 103, an inner thread 104, a fastening bolt 105, a suspension arm 106, a connecting frame 107, a suspension plate 108 and a through groove 109. There are two end plates 101, which are distributed left and right. The suspension rod 102 is fixedly installed between the left and right end plates 101. There are two suspension rods 102, which are distributed front and back. The sleeve 103 is slidably installed on the outer wall of the suspension rod 102. There are four sleeves 103, which are equally divided left and right. The suspension arm 106 is fixedly installed at the bottom of the front and rear sleeves 103. There are two suspension arms 106. The connecting frames 107 are distributed front and back and fixedly installed at the bottom of the suspension arm 106. The suspension plate 108 is fixedly installed at the bottom of the front and rear connecting frames 107.

[0021] Specifically, the distance between the left and right grabbing hooks 300 is adjusted according to the left and right lengths of the hoisted filter press frame. Specifically, after loosening the fastening bolts 105, the sliding sleeve 103 can be slid along the outer wall of the suspension rod 102, further driving the hoisting part 100, the coarse adjustment part 200, the grabbing hook part 300 and the lateral positioning part 400 to move. After moving the two grabbing hooks 300 to the appropriate positions, the fastening bolts 105 are tightened to ensure that the adjusted sliding sleeve 103 will not move again. The left and right end plates 101 are mounted on the hoisting hook of the winch by a wire rope, and the device is moved up and down by the winch. After the distance between the front and rear grabbing hooks 300 is roughly adjusted by the coarse adjustment part 200, the filter press frame is hooked by the front and rear grabbing hooks 300, and the hoisting part 100 is lifted upward by the winch, and the filter press frame is further hoisted upward to assist its installation.

[0022] For further details, please refer to Figure 5 , Figure 7 and Figure 8 As shown: The coarse adjustment unit 200 includes a linear guide rail 201, a linear slider 202, a coarse adjustment slide 203, a double-sided reduction motor 204, a lead screw 205, a push block 206 and a thread sleeve 207. The linear guide rail 201 is fixedly installed on the top left and top right of the hanging plate 108, the linear slider 202 is slidably installed on the periphery of the linear guide rail 201, the coarse adjustment slide 203 is located at the top of the hanging plate 108, and two coarse adjustment slides 203 distributed front and back are arranged on the top of the same hanging plate 108. The bottom of the coarse adjustment slide 203 is connected to the top of the hanging plate 108. The corresponding linear slider 202 is fixedly connected at the top by bolts, the bilateral reduction motor 204 is fixedly installed on the top of the lifting plate 108, the bilateral reduction motor 204 passes through the lifting plate 108 and extends to the periphery of its bottom, the lead screw 205 is fixedly installed on the output shafts at both ends of the bilateral reduction motor 204 through a coupling, the push-pull block 206 is fixedly installed at the bottom of the coarse adjustment slide 203, the thread sleeve 207 is fixedly installed inside the push-pull block 206, and the inner wall of the push-pull block 206 and the periphery of the lead screw 205 are threadedly connected.

[0023] Specifically, the front and rear lead screws 205 are driven to rotate by the output shafts at both ends of the bilateral reduction motor 204 to push the two threaded sleeves 207 in opposite directions. The two threaded sleeves 207 move through the connection of the two push-pull blocks 206 to push the front and rear coarse adjustment slides 203 in opposite directions. Since the coarse adjustment slide 203 is connected to the linear guide rail 201 through the linear slider 202, the movement of the coarse adjustment slide 203 can be ensured to be more stable and smooth. The front and rear coarse adjustment slides 203 move in opposite directions, and the front and rear hook distances of the hook portion 300 can be adjusted to hook the filter press frame with unequal front and rear widths. At the same time, the position of the hook portion 300 is roughly adjusted by the coarse adjustment portion 200, so as to shorten the operating stroke of the hook portion 300. On the one hand, it can improve the efficiency of hoisting, and on the other hand, it can also reduce the operating intensity of the hook portion 300, thereby improving the service life of the hook portion 300.

[0024] Furthermore, a straight groove 109 is formed through the top front end and the top rear end of the hanging plate 108, and the push-pull block 206 movably passes through the straight groove 109 and extends to the bottom periphery of the hanging plate 108. By forming a straight groove 109 through the top of the hanging plate 108, it plays the effect of making way for the push-pull block 206 to move, thereby preventing the movement of the push-pull block 206 from being interfered with by the hanging plate 108, and ensuring the free movement of the push-pull block 206.

[0025] For further details, please refer to Figure 2 to Figure 8 As shown: The hook portion 300 includes a linear cylinder 301, a push seat 302, a hook 303, a guide seat 304, a ball sleeve 305 and a slide rod 306. The linear cylinder 301 is fixedly mounted on the top of the front and rear coarse adjustment slides 203 respectively.

The push seat 302 is fixedly mounted on the output rod end of the linear cylinder 301. The grab hook 303 is fixedly installed on the side of the push seat 302 away from the linear cylinder 301 in a left-right distribution manner, the guide seat 304 is fixedly installed on the front and rear ends of the lifting plate 108, the ball sleeve 305 is fixedly installed at the four corners of the guide seat 304, the axis of the ball sleeve 305 is in the same direction as the axis of the linear cylinder 301, the slide rod 306 is slidably installed inside the ball sleeve 305, and the end of the slide rod 306 is fixedly connected to the side of the push seat 302 away from the grab hook 303; The lateral positioning part 400 includes a cylinder 401, a push rod 402, an air channel 4002, a first piston baffle 403, a second piston baffle 404, an air supply valve 405, an air distribution port 406, an air guide pipe 407, a pressure plate 408, a spring 409, a first speed regulating valve 4010, a second speed regulating valve 4011, a connecting plate 4012, a double-rod cylinder 4013, a rubber pad 4014, an air inlet 40011, a first air outlet 40012 and a second air outlet 40013. The cylinder 401 is fixedly mounted on the lower side of the push seat 302 away from the grab hook 303, and the push rod 402 is slidably mounted inside the cylinder 401. A first piston baffle 403 and a second piston baffle 404 are fixedly mounted on the outer wall of the push rod 402. The outer walls of the first piston baffle 403 and the second piston baffle 404 are The inner wall of the cylinder 401 is slidably connected, the airway 4002 is opened at the end of the push rod 402 away from the first piston baffle 403, the air distribution port 406 is opened on the outer wall of the push rod 402, the number of the air distribution ports 406 is multiple, and the air distribution ports 406 are distributed at equal angles. The air distribution ports 406 are connected to the inside of the airway 4002, and the air distribution ports 406 are located between the first piston baffle 403 and the second piston baffle 404. The air inlet 40011 is opened at the end of the cylinder 401 away from the grab hook 303, and the air supply valve 405 is fixedly installed inside the air inlet 40011. The air guide pipe 407 is fixedly installed between the second speed regulating valve 4011 and the air supply valve 405. The first air outlet 40012 and the second air outlet 40013 are both opened through the bottom of the cylinder 401, and the first speed regulating valve 4010 is fixedly installed inside the connecting plate 4012.

[0026] Specifically, when hoisting the filter press frame, the winch moves the device to the top of the filter press frame. Figure 1After the position is shown, the winch releases the device downward, so that the multiple grab hooks 303 on the front, back, left and right sides are placed on the inner side of the filter press frame, and the air is supplied to the inside of the air supply valve 405 through the outer wall air source, and enters the inside of the air supply valve 405 through the air guide pipe 407, and then enters the inside of the cylinder 401 through multiple air distribution ports 406, and is located in the area between the first piston baffle 403 and the second piston baffle 404, as shown in FIG. Fig.11 In the state shown, it finally enters the interior of the linear cylinder 301 through the first air outlet 40012 and the first speed regulating valve 4010, causing the output shafts of the two linear cylinders 301 in the front and rear directions to work outward, pushing the front and rear push seats 302 in opposite directions. Since the push seats 302 are connected by the sliding guide of the ball sleeve 305 and the slide rod 306, it can ensure that the movement of the push seats 302 is more stable and smooth. During the movement of the front and rear push seats 302, the grab hook 303 is also driven to move together, so that the grab hook 303 is stuck in the inner side of the front and rear I-beams of the filter press frame until the grab hook 303 in the front and rear directions abuts against the inner edge of the front and rear I-beams of the filter press frame, and the filter press frame is positioned front and back. Subsequently, the device is lifted by the winch, so that during the upward lifting of the grab hook 303, the upper surface of its horizontal end contacts the top wall of the front and rear I-beams of the filter press frame, thereby producing an upward lifting effect on the filter press frame, and the filter press frame is hoisted upward.

[0027] For further details, please refer to Figures 9 to 12 As shown: A second speed regulating valve 4011 is fixedly installed inside the second air outlet 40013, the output end of the first speed regulating valve 4010 is connected to the input end of the linear cylinder 301 through an air pipe, the connecting plate 4012 is fixedly installed at the bottom of the lifting plate 108, the double-rod cylinder 4013 is fixedly installed at the bottom of the connecting plate 4012, the input end of the double-rod cylinder 4013 and the output end of the second speed regulating valve 4011 are connected through an air pipe, the rubber pad 4014 is fixedly installed at the end of the output rod of the double-rod cylinder 4013, the pressure plate 408 is fixedly installed at one end of the push rod 402 close to the grab hook 303, the pressure plate 408 is located between the left and right grab hooks 303, the spring 409 is located on the periphery of the push rod 402, and the spring 409 is fixedly installed between the push seat 302 and the pressure plate 408.

[0028] Specifically, when the front and rear push seats 302 move in opposite directions, the cylinder 401, the push rod 402 and the pressure plate 408 are driven to move together until the surface of the pressure plate 408 contacts the inner side of the filter press frame. Then, as the push seat 302 continues to move, the pressure plate 408 is squeezed by the inner side of the filter press frame, pushing the push rod 402 toward the inside of the cylinder 401. The push rod 402 further drives the first piston baffle 403 and the second piston baffle 404 to move together. When the push seat 302 stops completely, the push rod 402 pushes the first piston baffle 403 and the second piston baffle 404 to the outer sides of the second air outlet 40013. Thereafter, the air input into the cylinder 401 through the air distribution port 406 is discharged at the first Under the sealing and blocking action of the piston baffle 403 and the second piston baffle 404, the air is delivered from the second air outlet 40013 and the second speed regulating valve 4011 to the inside of the rubber pad 4014, causing the output rod of the double-rod cylinder 4013 to work outward, pushing the rubber pad 4014 toward the left and right inner walls of the filter press frame until the left and right rubber pads 4014 abut against the left and right inner walls of the filter press frame, thereby providing a left and right positioning effect for the filter press frame, and cooperating with the front and rear grab hooks 303 to position the filter press frame front and back, ensuring that the filter press frame will not move front and back and left and right during the hoisting process, thereby ensuring the stability of the hoisting, and at the same time, no manual operation by workers is required, the hoisting efficiency is greatly improved, and the safety of the operation is also greatly improved.

[0029] In this scheme, when the auxiliary device for installing the filter press frame is working, the left and right end plates 101 are mounted on the hoisting hook of the winch by the steel wire rope, and the device is moved up and down by the winch; First, it is necessary to adjust the distance between the left and right hook parts 300 according to the left and right lengths of the filter press frame to be hoisted. Specifically, after loosening the fastening bolts 105, the sleeve 103 can be slid along the outer wall of the suspension rod 102, further driving the hoisting part 100, the coarse adjustment part 200, the hook part 300 and the lateral positioning part 400 to move. After moving the two hook parts 300 to the appropriate position, tighten the fastening bolts 105 to ensure that the adjusted sleeve 103 will not move again, and then start the bilateral reduction motor 204. The output shafts at both ends of the bilateral reduction motor 204 drive the front and rear lead screws 205 to rotate, and the two sleeves 203 are rotated. 07 is pushed in opposite directions, and the two wire sleeves 207 move through the connection of the two push blocks 206 to push the front and rear coarse adjustment slides 203 in opposite directions. Since the coarse adjustment slide 203 is connected with the linear guide rail 201 through the linear slider 202, the movement of the coarse adjustment slide 203 can be ensured to be more stable and smooth. The front and rear coarse adjustment slides 203 move in opposite directions to further push the front and rear two linear cylinders 301 and the front and rear two guide seats 304 to move together, and the front and rear push seats 302 are adjusted to a position suitable for the front and rear width of the filter press frame, and the front and rear grab hooks 303 are both located on the inner side of the filter press frame, such as Figure 1 Status shown; When hoisting the filter press frame, the winch moves the device to the top of the filter press frame. Figure 1 After the position is shown, the winch releases the device downward, so that the multiple grab hooks 303 on the front, back, left and right sides are placed on the inner side of the filter press frame, and the air is supplied to the inside of the air supply valve 405 through the outer wall air source, and enters the inside of the air supply valve 405 through the air guide pipe 407, and then enters the inside of the cylinder 401 through multiple air distribution ports 406, and is located in the area between the first piston baffle 403 and the second piston baffle 404, as shown in FIG. Fig.11 In the state shown, the first air outlet 40012 and the first speed regulating valve 4010 finally enter the interior of the linear cylinder 301, causing the output shafts of the two linear cylinders 301 in the front and rear directions to work outward, pushing the front and rear push seats 302 in opposite directions. Since the push seats 302 are connected by the sliding guide of the ball sleeve 305 and the slide rod 306, it can ensure that the push seats 302 move more stably and smoothly. During the movement of the front and rear push seats 302, the grab hooks 303 are also driven to move together, so that the grab hooks 303 are stuck in the inner sides of the front and rear I-shaped beams of the filter press frame until the grab hooks 303 in the front and rear directions abut against the inner edges of the front and rear I-shaped beams of the filter press frame, and the filter press frame is positioned front and back. Subsequently, the device is lifted by the winch, so that during the upward lifting of the grab hook 303, the upper surface of its horizontal end contacts the top wall of the front and rear I-shaped beams of the filter press frame, thereby producing an upward lifting effect on the filter press frame, and the filter press frame is hoisted upward; It should be noted that when the front and rear push seats 302 move in opposite directions, the cylinder 401, the push rod 402 and the pressure plate 408 are driven to move together until the surface of the pressure plate 408 contacts the inner side of the filter press frame. Then, as the push seat 302 continues to move, the pressure plate 408 is squeezed by the inner side of the filter press frame, pushing the push rod 402 toward the inside of the cylinder 401. The push rod 402 further drives the first piston baffle 403 and the second piston baffle 404 to move together. When the push seat 302 stops completely, the push rod 402 pushes the first piston baffle 403 and the second piston baffle 404 to the outer sides of the second air outlet 40013. Thereafter, the air input into the cylinder 401 through the air distribution port 406 is discharged. Under the sealing and blocking action of the first piston baffle 403 and the second piston baffle 404, the air is delivered from the second air outlet 40013 and the second speed regulating valve 4011 to the inside of the rubber pad 4014, causing the output rod of the double-rod cylinder 4013 to work outward, pushing the rubber pad 4014 toward the left and right inner walls of the filter press frame until the left and right rubber pads 4014 abut against the left and right inner walls of the filter press frame, thereby providing a left and right positioning effect for the filter press frame, and cooperating with the front and rear grab hooks 303 to position the filter press frame front and back, ensuring that the filter press frame will not move front and back and left and right during the hoisting process, thereby ensuring the stability of the hoisting, and at the same time, no manual operation by workers is required, the hoisting efficiency is greatly improved, and the safety of the operation is also greatly improved.
