Description

Technical Field

[0001] The utility model relates to the technical field of hoisting tools, in particular to a plate hammer hoisting tool for an impact crusher. Background Art

[0002] An impact crusher utilizes impact energy to crush materials. It is suitable for crushing medium-hard, brittle materials such as limestone, coal, gypsum, and shale. It is widely used in industries such as cement, electricity, building materials, chemicals, coal, and metallurgy. Impact crushers are primarily categorized into single-rotor and twin-rotor types. Single-rotor impact crushers offer a simpler structure, while twin-rotor impact crushers provide a more intense crushing process. Upon entering the crusher, material is first impacted by the high-speed rotating hammers on the rotor, causing it to break. The crushed material is then thrown onto the impact plate (impact plate) mounted above the rotor, where it is impacted again, further crushing it. The material then rebounds from the impact plate and enters the hammer zone again, repeating the crushing process. Within the crushing chamber, the material undergoes repeated impacts and back-movements until it reaches the desired particle size and is discharged through the discharge port. The hammers in an impact crusher are consumable parts and require frequent replacement to improve crushing efficiency. However, since the hammers typically weigh over 200 kilograms, replacement requires a crane or crane. However, due to structural design reasons, the upper part of the plate hammer of the existing impact crushers on the market is blocked by a frame, and generally needs to be hoisted at an angle. Since the installation angle of the plate hammer is very difficult to adjust, it is difficult for the existing hoisting tool to align the mounting hole on the rotor, resulting in a time-consuming and labor-intensive installation process and low work efficiency. A Chinese patent document with a publication date of May 21, 2014 and publication number CN103801428A discloses a plate hammer hoisting device, which relates to the field of engineering machinery technology and solves the technical problem of the existing technology that the operation of hoisting the plate hammer is time-consuming and labor-intensive. The plate hammer hoisting device includes a reciprocating telescopic mechanism and a support frame, wherein the reciprocating telescopic mechanism includes a fixed part and a movable part, the fixed part is fixed to the crusher, and the movable part can reciprocate in a predetermined direction relative to the fixed part; the support frame is fixedly connected to the movable part, and a hanging structure capable of hanging the plate hammer is provided on the support frame. When installing the blow hammer on the crusher, the blow hammer hoisting device first hooks the blow hammer to the mounting structure of the blow hammer hoisting device's support frame. The blow hammer's height is then adjusted to the appropriate position by adjusting the reciprocating telescopic mechanism. The blow hammer, at the appropriate height, is then mounted on the crusher, and the hook is separated from the blow hammer. However, this device cannot adjust the blow hammer's mounting angle, making it unsuitable for impact crushers where the upper portion of the blow hammer is obstructed by a frame. Utility Model Content

[0003] The purpose of the utility model is to solve the problems in the prior art that the plate hammer installation angle of the impact crusher is difficult to adjust and the lifting tool is difficult to align the mounting holes on the rotor, resulting in a time-consuming and labor-intensive installation process and low work efficiency. The utility model provides a plate hammer lifting tool for an impact crusher, which has the characteristics of simple structure, easy adjustment of the plate hammer installation angle and high installation efficiency.

[0004] The present invention addresses the above-mentioned technical problems by providing a tool for lifting the blow hammer of an impact crusher. The tool comprises a horizontal beam and two hooks symmetrically fixed at each end of the beam. A hanging device is mounted on the horizontal beam. The hook comprises a lifting arm connected to the horizontal beam at one end and a support bracket connected to the other end of the lifting arm. An angle adjustment mechanism is also provided on the top of the tool for adjusting the tool's angle. This tool is designed to simplify the blow hammer replacement process, improve work efficiency, and ensure operational safety. The horizontal beam is the primary load-bearing component of the tool, supporting the weight of the blow hammer. The hooks are symmetrically fixed at each end of the horizontal beam for directly lifting the blow hammer. The symmetrical dual hook design ensures a secure grip on the blow hammer, preventing it from slipping or falling during lifting. The lifting arm, which connects the horizontal beam and the support bracket, transmits the lifting force to the support bracket and leaves space for the blow hammer below. The support bracket is located at the other end of the lifting arm and directly contacts the blow hammer. The hanging device is mounted on the horizontal beam and is used to hang the entire tool from a crane or other lifting equipment. The angle adjustment mechanism adjusts the angle of the fixture based on the actual installation position, facilitating smooth entry of the blow hammer into the installation position and ensuring that the blow hammer is aligned with the mounting holes on the rotor. This reduces the difficulty of blow hammer installation and improves efficiency. This solves the existing problems of the blow hammer installation angle being extremely difficult to adjust and the difficulty of aligning the lifting fixture with the mounting holes on the rotor, resulting in a time-consuming and labor-intensive installation process and low efficiency. The fixture of the utility model significantly reduces the time and labor required to replace the blow hammer, while also reducing the risk of operator injury.

[0005] Preferably, the support bracket is L-shaped, its size adapted to the cross-sectional dimensions of the impact crusher's blow hammer. Because the blow hammer has a roughly rectangular cross-section, the L-shaped support bracket provides stable support for the hammer. Furthermore, the L-shaped support bracket has a smaller vertical projection when the blow hammer is suspended, making it easier to guide the hammer into position even when the frame shields the upper portion.

[0006] Preferably, the angle adjustment mechanism includes a sleeve and an adjustment rod inserted into the sleeve. The sleeve is located on the central plane of symmetry between the two hooks, and the adjustment rod extends upward and rearward of the hooks. The adjustment rod on the rear side of the hooks can be used to adjust the tilt angle of the hooks, thereby adjusting the tilt angle of the blow bars to ensure smooth insertion of the blow bars into the mounting holes on the rotor.

[0007] Preferably, when the hook is in the suspended state, the angle between the adjusting rod and the horizontal plane is 25-35 degrees. Since the mounting holes on the rotor are inclined, the angle between the mounting holes and the horizontal plane is approximately 30 degrees when the blow hammer is installed, while the angle between the blow hammer surface and the horizontal plane is approximately 60 degrees when the blow hammer is suspended. Therefore, the front side of the blow hammer (the side closest to the rotor) needs to be raised for insertion. Therefore, setting the angle between the adjusting rod and the horizontal plane at 25-35 degrees facilitates the downward pressing operation of the adjusting rod.

[0008] As another alternative, the angle adjustment mechanism includes two sleeves and adjustment rods inserted into the sleeves. The sleeves are symmetrically fixed to the two hooks, and the adjustment rods extend toward the rear of the hooks. Compared to the previous single adjustment rod solution, this solution can be operated by two people, reducing operator stress.

[0009] Preferably, the lifting arm is arc-shaped, the lifting arm and the supporting frame are an integrated structure, and the hook is overall C-shaped. The lifting arm and the supporting frame are an integrated structure, which can ensure the mechanical strength of the hook.

[0010] Preferably, a connecting beam is provided between the lifting arms of the two hooks, and the two ends of the sleeve are fixed to the cross beam and the connecting beam respectively. The connecting beam is provided between the lifting arms to improve the structural strength of the tooling and to improve the structural stability of the tooling.

[0011] Preferably, the sleeve is a round tube with a sealing plate at one end near the crossbeam, and the adjusting rod is a round rod. When adjusting the angle of the blow hammer, the main actions of the adjusting rod are to press down to adjust the inclination angle of the blow hammer in the front-to-back direction and to push forward to move the blow hammer forward. The sealing plate can limit the adjustment position and prevent the adjusting rod from moving forward.

[0012] Preferably, the sleeve is a square tube with a sealing plate at one end near the crossbeam. The adjusting rod is a square rod with a crossbar at the grip end. The adjusting rod is T-shaped. The T-shaped adjusting rod not only allows the fore-aft tilt angle of the blow bar to be adjusted by pressing down or lifting it, but also allows the crossbar on the adjusting rod to be rotated to fine-tune the left-right angle of the blow bar, thereby ensuring that the blow bar accurately enters the mounting hole on the rotor.

[0013] Preferably, the hook is formed by welding a front plate and a rear plate, the front plate and the rear plate are perpendicular to each other, and the cross section of the hook is T-shaped.

[0014] The beneficial effect of the utility model is that it effectively solves the problems of the prior art that the plate hammer installation angle of the impact crusher is difficult to adjust and the lifting tool is difficult to align the installation hole on the rotor, resulting in a time-consuming and labor-intensive installation process and low work efficiency. The impact crusher plate hammer lifting tool of the utility model has the characteristics of simple structure, easy adjustment of the plate hammer installation angle and high installation efficiency.

[0023] The specific implementation of the technical solution of the utility model will be further described below through examples and in conjunction with the accompanying drawings.

[0024] Example 1

[0025] exist Figure 1 Figure 2 In the embodiment 1 shown, a plate hammer lifting fixture for an impact crusher is provided. The fixture comprises a crossbeam 1 and two hooks 2 symmetrically fixed at both ends of the crossbeam 1. A hanging device 3 is provided on the crossbeam 1. The hook 2 comprises a lifting arm 4 connected to the crossbeam 1 at one end and a supporting bracket 5 connected to the other end of the lifting arm 4. An angle adjustment mechanism for adjusting the angle of the fixture is also provided on the upper part of the fixture. The design of the fixture of the utility model is intended to simplify the replacement process of the plate hammer, improve work efficiency, and ensure the safety of operation. The crossbeam 1 is the main load-bearing part of the fixture and is made of high-strength steel to bear the weight of the plate hammer. The hanging device 3 is provided on the crossbeam 1 and is used to hang the entire fixture on a crane or other lifting equipment such as an electric hoist (see Figure 6(The lifting equipment and the crusher frame that blocks the hammer from entering are not shown in the figure). The hanging device 3 is made of round steel or steel bars bent into a circular shape and welded to the center of the beam 1.

[0026] The hook 2 is symmetrically fixed at both ends of the crossbeam 1 and is used to directly lift the plate hammer 6. The design of the hook 2 ensures that the plate hammer 6 can be firmly grasped and will not slide or fall during the lifting process. The hook 2 of this embodiment is composed of a front plate 12 and a rear plate 13 welded together. The front plate 12 and the rear plate 13 are perpendicular to each other, and the cross section of the hook 2 is T-shaped. The front plate 12 and the rear plate 13 of the hook 2 are welded perpendicular to each other to form a T-shaped cross section. The hook 2 consists of two main parts, namely the front plate 12 and the rear plate 13, wherein the front plate 12 is in contact with the plate hammer 6 as a plane (see Figure 3 Figure 4 ), which can ensure the stability of the plate hammer 6; the rear plate 13 is mainly used to provide structural strength and prevent the hook 2 from deforming. The two parts are connected together by welding to form the main structure of the hook 2. The cross section of the hook 2 is T-shaped. This design can reduce the weight of the hook 2 and save costs while ensuring the structural strength of the hook 2. When the hook 2 of this embodiment is in the suspended state, the angle between the adjusting rod 8 and the horizontal plane is 30 degrees (see Figure 3 Since the mounting holes on the rotor 14 are tilted, the angle between the mounting holes and the horizontal plane is about 30 degrees when the plate hammer 6 is installed, and the angle between the plate surface and the horizontal plane is about 60 degrees when the plate hammer 6 is hung. Therefore, when the plate hammer 6 is inserted, the front side (close to the rotor side) of the plate hammer 6 needs to be raised. Therefore, the angle between the adjusting rod 8 and the horizontal plane is 30 degrees, which is convenient for the downward operation of the adjusting rod 8. That is, when the adjusting rod 8 is pressed down and is close to parallel to the horizontal plane (see Figure 5 ), the inclination angle of the plate hammer 6 is consistent with the angle of the mounting hole, which is conducive to the plate hammer 6 entering the mounting hole.

[0027] The lifting arm 4 connects the crossbeam 1 and the support bracket 5. Its function is to transmit the lifting force to the support bracket 5 and support the weight of the plate hammer 6. In this embodiment, the lifting arm 4 is curved and integrally formed with the support bracket 5. The hook 2 is generally C-shaped. The integral structure of the lifting arm 4 and the support bracket 5 ensures the mechanical strength of the hook 2. The integral structure of the lifting arm 4 and the support bracket 5 means that they are manufactured as a single component, which ensures the integrity and stability of the hook 2 during the lifting process and reduces the risk of problems caused by connection problems. Furthermore, the design of the C-shaped hook 2 provides a stable hook point while leaving ample space for the operator to easily attach the plate hammer 6. Both the curved lifting arm 4 and the C-shaped hook 2 contribute to the structural strength of the entire lifting tooling, which is crucial for lifting heavy plate hammers. The C-shaped hook 2 makes it easier for the operator to insert and remove the plate hammer 6 from the hook 2, improving work efficiency.

[0028] The support bracket 5 is located at the other end of the lifting arm 4 and is in direct contact with the plate hammer 6 during operation, ensuring the stability of the plate hammer 6 during the lifting process. The support bracket 5 of this embodiment is L-shaped, and the size of the support bracket 5 is adapted to the cross-sectional size of the impact crusher plate hammer 6. In the impact crusher plate hammer lifting tooling, the L-shaped design of the support bracket 5 and the size adapted to the cross-sectional size of the plate hammer 6 are intended to ensure stability and safety during the lifting process. The L-shaped design of the support bracket 5 has a vertical portion and a horizontal portion. Since the hanging device 3 is mounted on the crossbeam 1, and the crossbeam 1 is located at one end of the lifting arm 4, the support bracket 5 is located at the end of the lifting arm 4 away from the crossbeam 1. Therefore, when the plate hammer 6 is actually lifted, the L-shaped support bracket 5 is in an inclined state during operation, and the angle between the vertical side of the L-shape and the horizontal plane is about 60 degrees. This design helps to ensure that the support bracket 5 can firmly support the weight of the plate hammer 6 and provide good stability during lifting. The size of the support bracket 5 is adapted to the cross-sectional dimensions of the blow hammer 6. This means that the support bracket 5 can accommodate the blow hammer 6 and is slightly larger than the blow hammer 6. This minimizes the size of the support bracket 5 and facilitates installation of the blow hammer 6. Furthermore, since the cross-sectional dimensions of the support bracket 5 match those of the blow hammer 6, they provide uniform support, avoiding uneven loading caused by size mismatches and thus improving the stability of the blow hammer 6. Furthermore, the support bracket 5, which is adapted to the cross-sectional dimensions of the blow hammer, simplifies the lifting process, making it easier for operators to position the blow hammer in the correct position.

[0029] The angle adjustment mechanism allows the operator to adjust the angle of the fixture as needed to facilitate alignment of the blow hammer 6 with the mounting hole. The angle adjustment mechanism consists of a sleeve 7 and an adjustment rod 8 plugged into the sleeve 7. The sleeve 7 is located on the center plane of symmetry between the two hooks 2, and the adjustment rod 8 extends toward the rear of the hooks 2. The angle adjustment mechanism is a key component of the lifting fixture of this utility model, improving lifting efficiency. The operator adjusts the angle of the fixture (blow hammer) as needed to suit the actual position between the blow hammer and the mounting hole. The sleeve 7 is the fixed portion of the adjustment mechanism, fixed to the center plane of symmetry between the two hooks 2 in the middle of the crossbeam 1. The sleeve 7 provides a stable support point for the adjustment rod 8 to be inserted and used to push, pull, and rotate the fixture. The adjustment rod 8 is the component that actually performs the angle adjustment. It plugs into the sleeve 7 and can be adjusted by rotating the hooks 2 horizontally or pressing down (or lifting) the adjustment rod 8 to change the fixture's tilt angle, thereby adjusting the overall angle of the blow hammer 6. Since the adjustment lever 8 primarily pushes the fixture forward (toward the blow hammer mounting location), deflects it left or right, and presses (or lifts) downward, the lever 8 generally does not need to be fixed to the sleeve 7 for ease of operation. Of course, the angle adjustment mechanism may also include a locking mechanism, such as a screw, latch, or pin, to secure the relative position of the adjustment lever 8 and sleeve 7. The sleeve 7 is located on the symmetrical center plane of the two hooks 2. This ensures that the fixture is balanced on both sides, ensuring the stability of the blow hammer during lifting and allowing the operator to quickly and easily adjust the fixture angle without complicated manipulation or the use of additional tools. The adjustment lever 8 extends upward and behind the hooks 2. This orientation facilitates access from behind the fixture, providing ample space for adjusting the blow hammer 6 angle without entering the dangerous area near the hooks 2. Furthermore, the adjustment lever should be designed with user experience in mind, ensuring operator comfort when adjusting the angle. For example, a rubber grip can be provided at the operating end of the adjustment lever to facilitate operation and reduce fatigue. The sleeve 7 of this embodiment is a round tube with a sealing plate 10 at one end near the crossbeam 1. The adjustment rod 8 is a round rod. When adjusting the angle of the plate hammer 6, the main action of the adjustment rod is to press down to adjust the inclination angle of the plate hammer 6 in the front-to-back direction and to push forward to propel the plate hammer 6 forward. The sealing plate 10 limits the adjustment position and prevents the adjustment rod from moving forward. Furthermore, when adjusting the angle of the plate hammer, the main action of the adjustment rod is to press down to adjust the inclination angle of the plate hammer in the front-to-back direction and to push forward to propel the plate hammer 6 forward. The sealing plate 10 limits the adjustment position and prevents the adjustment rod from moving forward. The grip end of the adjustment rod is also designed with a portion that facilitates the operator's grip and operation, which can be a handle with a non-slip texture or a rubber handle cover.

[0030] In this embodiment, a connecting beam 9 is provided between the lifting arms 4 of the two hooks 2. The ends of the sleeve 7 are fixed to the crossbeam 1 and the connecting beam 9, respectively. The connecting beam 9 is a crucial component of the lifting fixture, connecting the lifting arms 4 of the two hooks 2 and providing a stable structural framework. This design helps distribute forces during lifting and reduces stress concentration on a single crossbeam 1. The ends of the sleeve 7 are fixed to the crossbeam 1 and the connecting beam 9, respectively. This arrangement ensures the reliability of the angle adjustment mechanism. Typically, the front end of the sleeve 7 is welded to the bottom of the crossbeam 1, and the rear end (where the adjustment rod is inserted) is welded to the top of the connecting beam 9. To position the rear end of the sleeve higher than the front end, the crossbeam 1 can be extended upward to facilitate welding. For example, if the crossbeam 1 and connecting beam 9 are plate-like structures, the connecting beam 9 can be wide in the middle and narrow at the ends. By providing the connecting beam 9 between the lifting arms 4, the structural rigidity of the entire fixture is enhanced. This design helps maintain the stability of the fixture when lifting heavy objects and reduces potential risks caused by twisting or bending. The presence of the connecting beam 9 helps evenly distribute the load between the two hooks 2, which is crucial for ensuring balance during lifting, especially when the blow bar is heavy. This fixture is designed with practical convenience and safety in mind, making blow bar replacement more efficient and safer. In practice, this fixture can significantly reduce the time and labor required to replace the blow bar, while also reducing the risk of operator injury.

[0031] Example 2

[0032] The impact crusher hammer lifting fixture of Example 2 features an angle adjustment mechanism comprising two sleeves and adjustment rods connected to the sleeves. The sleeves are symmetrically fixed to two lifting hooks, and the adjustment rods extend toward the rear of the hooks. The rest of the mechanism is the same as in Example 1. The angle adjustment mechanism of this example utilizes a more complex and stable system, achieving angle adjustment of the fixture by mounting sleeves and adjustment rods on two separate lifting hooks. This example utilizes two sleeves, rather than the single sleeve of Example 1, allowing for separate angle adjustment on both hooks. This symmetrical arrangement helps maintain the fixture's balance, particularly when lifting hammers with uneven weight distribution. The sleeves are symmetrically fixed to the two lifting hooks, ensuring that each hook has a corresponding sleeve and adjustment rod, ensuring symmetry and balance during angle adjustment. The adjustment rod, the component that actually performs the angle adjustment, is connected to the sleeves. As needed, the fixture's tilt angle can be adjusted by rotating the hooks horizontally or pressing down (or lifting) the adjustment rod to change the overall angle of the hammer. Unlike the previous embodiment, the adjustment lever in this embodiment can also adjust the left-right angle of the blow hammer. For example, if the right side of the blow hammer is higher than the left, the angle can be adjusted by pressing down on the right adjustment lever and lifting up on the left and right adjustment levers. Since the adjustment lever primarily pushes the tooling forward (toward the blow hammer mounting location), deflects it left or right, and presses down (or lifts it), the adjustment lever generally does not need to be fixed to the sleeve for ease of operation. Of course, the angle adjustment mechanism may also include a locking mechanism, such as a screw, clip, or latch, to secure the relative position of the adjustment lever and sleeve. The section lever extends upward and behind the hook. This orientation facilitates operator access to the adjustment lever from behind the tooling, providing ample space for adjusting the blow hammer angle without having to enter the dangerous area below the hook. Furthermore, the adjustment lever should be designed with user experience in mind, ensuring operator comfort when adjusting the angle. For example, a rubber grip could be provided at the operating end of the adjustment lever to facilitate operation and reduce fatigue.

[0033] Example 3

[0034] exist Figure 7In the illustrated embodiment 3, the sleeve 7 is a square tube with a sealing plate at one end near the crossbeam 1. The adjusting rod 8 is a square rod with a crossbar 11 at the grip end of the adjusting rod 8. The crossbar 11 has a circular cross section and the adjusting rod is T-shaped as a whole. The rest is the same as in embodiment 1 or embodiment 2. Using a square tube as the sleeve prevents the adjusting rod 8 from rotating within the sleeve 7. Therefore, rotating the adjusting rod 8 can drive the sleeve 7 and the tooling to rotate. This rotation can be used to adjust the angle of the plate hammer in the left-right direction. For example, if the right side of the plate hammer is higher than the left side, the angle of the plate hammer can be adjusted by rotating the adjusting rod 8 to facilitate the plate hammer's entry into the mounting hole. In addition, when adjusting the plate hammer angle, the main action of the adjusting rod is to press down to adjust the plate hammer's tilt angle in the front-to-back direction and to push forward to move the plate hammer forward. The sealing plate 10 can limit the adjustment position and prevent the adjusting rod from moving forward. The T-shaped design of the adjustment lever means it has a crossbar 11 at the operating end, perpendicular to the main lever. This allows the lever to function as a lever, allowing the operator to apply rotational force through the crossbar 11 (the grip end) to adjust the left-right angle of the blow bar, thereby changing the angle of the tooling. The crossbar 11 at the grip end of the adjustment lever provides a comfortable grip, making it easier for the operator to hold and turn the lever. Furthermore, the crossbar's design should also take user experience into consideration, ensuring operator comfort when adjusting the angle. For example, a rubber grip could be provided on the crossbar for easier operation.

[0035] When the plate hammer of the tooling of the present invention is hoisted, the plate hammer 6 is first placed on the hook 2 of the tooling, and then the tooling is raised by a lifting device (such as Figure 3 Figure 4 State), when the hook 2 of the tooling is in a hanging state, the angle between the adjusting rod and the horizontal plane is about 30 degrees. Since the mounting hole on the rotor 14 is in an inclined state, the angle between the mounting hole and the horizontal plane is about 30 degrees (the upper part of the plate hammer 6 is blocked by the frame at a position where the angle is greater than 30 degrees), and when the plate hammer is hung, the angle between its plate surface and the horizontal plane is about 60 degrees. Therefore, when the plate hammer 6 enters, it is necessary to lift the front side of the plate hammer (close to the rotor side). When the plate hammer 6 on the hook 2 is close to the plate hammer mounting hole on the rotor 14, the adjusting rod is pressed down, that is, the adjusting rod is pressed down to be close to parallel with the horizontal plane (see Figure 5 ), the inclination angle of the plate hammer 6 matches the angle of the mounting hole. At this time, the plate hammer 6 is pushed forward by the adjusting rod and the angle is fine-tuned. By coordinating the lifting and lowering of the lifting equipment, the plate hammer 6 can be easily introduced into the mounting hole.

[0036] In addition to the above-mentioned embodiments, within the scope disclosed in the claims and description of the present utility model, the technical features or technical data of the present utility model can be reselected and combined to form new embodiments. These can be achieved by those skilled in the art without creative work. Therefore, these embodiments that are not described in detail in the present utility model should also be regarded as specific embodiments of the present utility model and within the scope of protection of the present utility model.
