Description

Roller system side-pull type roller press and roller system side-pull assembling and unloading method

Technical field

The invention relates to the technical field of roller press assembly, in particular to a roller system side pull type roller press and a roller system side pull assembly and disassembly method.

Background technique

With the advancement of grinding technology in recent years, roller presses have developed rapidly due to their high energy efficiency. They have grown from miniaturization to larger ones, and penetrated from the cement and building materials industry to the metallurgical and mining industry. Since roller presses are now developing to medium and large specifications, large lifting tools are required in the installation and disassembly process of large roller presses, which increases the construction and maintenance costs of roller press users. At the same time, because the roller sleeve of the roller press will inevitably wear out during use, especially in the metallurgical and mining industry, the hardness of the ore is relatively high, and the roller sleeve wears fast. It must be shut down regularly for maintenance and the roller sleeve should be replaced. Therefore, if the roller sleeve can be quickly replaced after wear, it can provide great convenience for production work.

The Chinese invention patent with publication number CN2721636 discloses a combined frame roller press, which is used in the cement preparation industry. The roller press uses a combined frame to replace the traditional welded frame, and the hinged joints between the frame parts replace the saddle seams. Pin and bolt connection to simplify the connection method of the roller press, and the combined frame roller press overcomes the defect of low load carrying capacity of the existing roller press, and reduces the installation and disassembly process of the roller press Difficulty. However, the combined frame roller press still needs to remove the top four load-bearing pins and hoist the roller system to realize the roller system replacement, and the roller system side pulling action cannot be carried out to realize the rapid replacement of the roller system.

Summary of the invention

The purpose of the present invention is to solve the problem that the existing roller press requires large-scale hoisting equipment to assist in the replacement and installation of the roller system. On the basis of the auxiliary transportation device on the opening and closing side, in conjunction with the trolley and the drive system, it greatly shortens the maintenance and replacement time of the roller system and reduces the difficulty of the maintenance and replacement. There is no need for large-scale hoisting equipment to assist in the replacement and installation of the roller system.

The technical scheme adopted by the present invention is as follows:

A side-pull roller press with a roller system, comprising a frame and a roller system. The frame includes an upper frame, a lower frame and an opening and closing side. The upper end of the opening and closing side is detachably connected to the upper frame. The lower end of the opening and closing side is connected to the lower frame and is relatively rotatable. After the opening and closing side rotates relative to the lower frame, the surface of the lower frame and the upper surface of the opening and closing side together form a roller moving channel. An auxiliary transportation device is provided, and the roller system is matched with the auxiliary transportation device and enters and exits the frame along the auxiliary transportation device.

Due to the above technical solution, when the roller system is loaded and unloaded, the opening and closing sides of one or both sides are opened, so that the lower frame surface and the upper surface of the opening and closing side jointly form a roller system moving channel, and force is applied to the side of the roller system, namely The driveable roller system enters and exits the frame along the auxiliary transportation device. The entire loading and unloading process does not require large-scale lifting equipment to assist the lifting of the roller system, which greatly reduces the time for the maintenance and replacement of the roller system and reduces the difficulty of the maintenance and replacement of the roller system.

Further, the auxiliary transportation device is a guide rail arranged along the length of the moving channel of the roller system, the lower surface of the end of the roller system is provided with a guide rail groove matching the guide rail, and the guide rail and the guide rail groove cooperate with each other so that the roller system can be The guide rail moves.

As a result of the above-mentioned technical solution, the guide rail not only assists in the transportation of the roller system, but also plays a guiding role, which effectively improves the accuracy of the installation process. During the installation of the roller system, the risk of incorrect installation of the roller system is effectively reduced.

Further, an auxiliary device for fixing the upper frame when the rollers are pulled sideways is arranged outside the frame, and the auxiliary device is arranged at an end of the upper frame close to the opening and closing side and provides a supporting force for the upper frame.

Due to the adoption of the above technical solution, when the roller system is replaced by one-side side pull, the auxiliary device provides a certain supporting force for the upper frame, which stabilizes the frame and prevents the frame from being displaced or deformed due to the movement of the roller system.

Further, the rotatable angle θ of the opening and closing side is greater than or equal to 90°.

Due to the possibility of uneven foundation/ground, a too small rotatable angle θ will cause the upper end of the opening and closing side to hang. When the roller system moves to the opening and closing side, it is very likely that the opening and closing side connection will be damaged and broken. With the technical solution, when the opening and closing side can rotate at an angle θ≥90°, similar accidents can be greatly avoided.

Further, a center piece for supporting the upper frame and strengthening the frame is detachably installed between the upper frame and the lower frame.

Due to the adoption of the above technical solution, two central pieces can be preferably arranged on the machine frame, and the two central pieces are symmetrically arranged on both sides of the roll gap of the pair of rollers. The center piece can strengthen the structure of the frame, and when the frame is opened and closed on one side or on both sides for side-pull and translation close to the opening and closing side roller system, the center piece provides support for the upper frame, eliminating the need to configure additional equipment Fix the upper frame or remove the upper frame and then pull it laterally.

Further, a support pad is provided on the lower surface of the opening and closing side; when the opening and closing side is in a down state, the support pad is supported on the foundation to ensure that the upper surface of the opening and closing side maintains a horizontal support state relative to the roller system; The height of the support block can be adjusted.

Due to the above technical solution, the support pad can provide support for the opening and closing side in the down state, and the rotation angle θ of the opening and closing side can be adjusted by adjusting the support pad as needed to ensure that the upper surface of the opening and closing side is opposite to the roller The system maintains a horizontal support state, improves the safety factor of the roller system during transportation, increases the service life of the opening and closing side joints, and avoids the opening and closing side joints from being broken due to careless operation.

Further, it also includes a trolley and a drive system. The trolley is mated with the opening and closing side in the down state. The upper surface of the trolley is provided with auxiliary guide rails, so that the roller system can follow the auxiliary transportation device under the traction of the driving system. Slide in and out of the trolley horizontally with the auxiliary guide rail.

Due to the above technical solution, after the trolley is mated with the opening and closing sides, there is no need to manually check the alignment. The roller system on the trolley can be directly pulled into the frame through the drive system to complete the installation, or the roller system can be directly installed. Pull to the trolley, in the process of roller system maintenance and replacement, there is no need for large hoisting equipment to assist in roller system replacement and installation. The operation process is simple, saves the time of roller system maintenance and replacement, and reduces the loss caused by the shutdown of the roller press; The trolley transports the roller system to the designated place for maintenance or replacement, and the transfer is flexible, which makes up for the inability of large lifting equipment to move.

Further, the driving system is arranged on the other side of the trolley and the frame; the driving system includes a hoist symmetrically distributed with respect to the two ends of the roller system and a hoist base on which the hoist is installed on the foundation, and the hoist passes through a pulley block And the steel wire rope connected to the roller set on the pulley block.

Two winches are installed on the opening and closing side of the frame symmetrically with respect to the two ends of the roller system; the pulley block can reduce the power requirement of the winch, and the combination of the pulley block can be Choose according to plant conditions and hoisting machine parameters and other restrictive conditions.

Further, when the roller system is moved out of the frame from the opening and closing side, the pulley block includes a fixed pulley connected to the base of the hoist and a movable pulley connected to the end of the roller system, wherein the hook b of the fixed pulley is detachably connected to the base of the hoist , The hook a of the movable pulley is detachably connected to the end of the roller system, the free end of the wire rope is wound on the hoist, and the fixed end of the wire rope sequentially bypasses the movable pulley and the fixed pulley and is fixed on the lifting lug of the movable pulley.

Due to the adoption of the above technical solution, the movable pulley and the fixed pulley cooperate with each other, so that the hoist can pull the roller system out of the frame with less effort.

Further, when the roller system enters the frame from the opening and closing side, the pulley block includes a fixed pulley connected to the closed side and a movable pulley connected to the end of the roller system, wherein the hook b of the fixed pulley is detachably connected to the frame The end far away from the closing side, the hook of the movable pulley a detachable connecting roller system end, the free end of the wire rope is wound on the hoist, the fixed end of the wire rope goes around the fixed pulley and the movable pulley in turn and is fixed on the lifting lugs of the fixed pulley .

Due to the adoption of the above technical solution, the movable pulley and the fixed pulley cooperate with each other, so that the hoist can pull the roller system into the frame in a labor-saving manner.

Further, the center distance L2 of the hoist is greater than or equal to the distance L1 between the two ends of the roller system.

Due to the above technical solution, the center distance L2 of the two winches is greater than or equal to the distance L1 between the two ends of the roller system. This setting can prevent the wire rope from rubbing against the frame or the roller system, and prevent the wire rope from wearing too fast or suddenly breaking during operation. .

The side is detachable and fixedly connected; the end face of the trolley butting with the opening and closing side is provided with a buffer gasket.

Due to the above technical solution, the laying of the track can limit the movement trajectory of the trolley. On the one hand, it can avoid repeating the correction of the trolley's alignment position when installing the roller system. On the other hand, the track can reduce environmental restrictions such as uneven foundations and make the trolley move smoothly. When the roller system moves from the opening and closing side to the auxiliary guide rail of the trolley, the trolley and the opening and closing side are fixedly connected by the connecting piece to avoid the displacement of the trolley relative to the frame due to friction; the buffer gasket reduces the trolley The impact generated when butt with the opening and closing side.

Further, a positioning block A and a positioning block B are detachably connected at both ends of the auxiliary rail, and the positioning block A and the positioning block B cooperate with each other to restrain the roller system.

Since the weight of the roller system is much larger than that of a smaller car, the position of the roller system on the trolley is too deviated, which will cause the trolley to overturn. Due to the above technical solution, positioning block A assists the positioning of the roller system so that the center of gravity of the roller system is on the center line of the trolley. The positioning block A and positioning block B cooperate with each other to limit the displacement of the roller system on the trolley and prevent the roller system from being transported on the trolley. During the process of sliding, the safety factor of the roller system during transportation is improved.

Further, the auxiliary rail is provided with at least two sets of mounting holes in different positions, and the positioning block A and the positioning block B are detachably fixedly connected to the auxiliary rail through the mounting holes.

In the actual production process, it can be known that the center of gravity of the fixed roller system and the movable roller system are different, and the balance positions placed on the trolley are also different. Due to the adoption of the above technical solution, by providing at least two sets of mounting holes in different positions, the positioning block A can adjust the mounting position to assist the fixed roller system and the movable roller system in accurately positioning their respective balance positions.

Correspondingly, the present invention also discloses a side-pull loading and unloading method of the roller system, which includes the following steps:

It should be understood that the specific embodiments described here are only used to explain the present invention, but not used to limit the present invention.

Example 1

A roller system side pull type roller press, as shown in FIG. 1, includes a frame 1 and a roller system. The roller system includes a movable roller system 4 and a fixed roller system 5 arranged oppositely. The frame 1 includes an upper The frame, the lower frame and the opening and closing sides 1-5. The upper frame includes two upper beams 1-4 and at least two upper longitudinal beams. The two upper transverse beams 1-4 are arranged in parallel. A closed frame structure is formed between the upper beams 1-4. The lower frame includes two lower transverse beams 1-3 and at least two lower longitudinal beams. The two lower transverse beams 1-3 are arranged in parallel, and the two ends of the lower longitudinal beam are connected by bolts to form a closed frame between the two lower transverse beams 1-3. structure.

The frame 1 is single-sided opening and closing, that is, only one side is the opening and closing side 1-5, and the other side opposite to the opening and closing side 1-5 is the closed side, and the side close to the fixed roller system 5 can be set As the opening and closing side, the side close to the movable roller system 4 can also be set as the opening and closing side. The upper end of the opening and closing side 1-5 is detachably connected to the upper frame, the lower end of the opening and closing side 1-5 is connected to the lower frame and can rotate relatively, and the opening and closing side 1-5 is rotatable relative to the lower frame Afterwards, the surface of the lower frame and the upper surface of the opening and closing sides 1-5 together form a roller system moving channel. The roller system moving channel is provided with an auxiliary transportation device, and the roller system cooperates with the auxiliary transportation device and enters and exits along the auxiliary transportation device. Rack 1. Optionally, the upper and lower ends of the opening and closing side 1-5 are respectively connected to the upper frame and the lower frame through load-bearing pins 1-7, and the upper end of the opening and closing side 1-5 and the upper frame are disconnected by disassembling the load-bearing pins 1-7, The opening and closing side 1-5 can rotate around the axis of the bearing pin 1-7 at the lower end.

The auxiliary transportation device is a guide rail arranged along the length direction of the moving channel of the roller system. The lower surface of the end of the roller system is provided with a guide rail groove matching the guide rail. The guide rail and the guide rail groove cooperate with each other so that the roller system can move along the guide rail. While the guide rail assists in the transportation of the roller system, it also plays a guiding role, effectively improving the accuracy of the installation process. During the installation of the roller system, the risk of incorrect installation of the roller system is effectively reduced.

Optionally, the guide rails include lower frame guide rails 1-1 installed on the lower frame, and end guide rails 1-6 installed on the opening and closing sides 1-5.

The rotatable angle θ of the opening and closing sides 1-5 is greater than or equal to 90°. Specifically, due to the possibility of uneven foundation/ground, a too small rotatable angle θ will cause the upper end of the opening and closing side 1-5 to hang, and the roller system will most likely cause opening and closing when it moves to the opening and closing side 1-5. The connection of side 1-5 is damaged and broken. When the opening and closing side can rotate at an angle θ≥90°, similar accidents can be greatly avoided.

A center piece 1-9 for supporting the upper frame and strengthening the frame 1 is detachably installed between the upper frame and the lower frame.

Specifically, the support pad 1-8 can provide support for the opening and closing side 1-5 in the down state, and the rotation angle θ of the opening and closing side 1-5 can be adjusted by adjusting the support pad 1-8 as needed. , To ensure that the upper surface of the opening and closing side 1-5 remains horizontally supported relative to the roller system, which improves the safety factor of the roller system during transportation, improves the service life of the connection between the opening and closing side 1-5, and avoids accidental operation The opening and closing side 1-5 joints are broken.

When removing the roller system, turn down the opening and closing side 1-5, pull out the roller system close to the opening and closing side 1-5, remove the center piece 1-9, and then use the auxiliary device 3-8 to hang the upper cross beam 1-4 close to The end position of the opening and closing side 1-5 firmly holds the upper cross beam 1-4, and the other roller system is pulled out. The installation process of the roller system is opposite to the disassembly process, so I won't repeat it here. The entire loading and unloading process does not require large-scale lifting equipment to assist the lifting of the roller system, which greatly reduces the time for the maintenance and replacement of the roller system and reduces the difficulty of the maintenance and replacement of the roller system.
