Description

Technical Field

[0001] This utility model relates to the field of mechanical disassembly tools, and in particular to disassembly tools. Background Technology

[0002] In the production of fluid foods, material separation and filtration are common processes. Separators use centrifugal force generated by high-speed rotation to separate fluid foods. To ensure the stability and safety of the separator under high-speed operation, regular maintenance and replacement of worn parts are necessary. The drum, as the core component of the separator, is particularly critical during disassembly. Currently, drum disassembly mainly relies on custom tools provided by the manufacturer, using manual tapping and vibration to loosen and disassemble it. This method is not only inefficient but also poses significant safety hazards.

[0003] In related technologies, common tools for disassembling separator drums are mostly Y-shaped or Q-shaped stainless steel plate structures. Holes are drilled in the plate, and screws are used to secure it to the screw-on locking mechanism on the drum. Maintenance personnel need to use tools such as hammers or copper rods to repeatedly tap the handle of the disassembly tool, using vibration to loosen the screw-on locking mechanism. However, this manual tapping method has many drawbacks: the operation is time-consuming and labor-intensive, increasing the workload of maintenance personnel; it is difficult to precisely control the force and direction when manually swinging the tool, easily causing tool damage or personnel injury; the impact force generated during the tapping process may damage other parts of the equipment, affecting the overall performance of the equipment.

[0027] In existing technologies, separators used in the production of fluid foods require regular maintenance and replacement of worn parts. The drum is typically disassembled using Y-shaped or Q-shaped stainless steel plates secured with screws, relying on manual hammering and vibration to complete the disassembly. Traditional methods are inefficient and pose significant safety hazards. During operation, improper force can easily cause tools to slip or parts to be damaged, and the hammering force is difficult to control precisely, potentially causing secondary damage to the equipment.

[0028] Therefore, please refer to the following: Figures 1 to 3This application discloses a disassembly tool comprising a drum clamp 1, a retaining ring 2, and an ejection mechanism 3. The drum clamp 1 includes a clamp body 11 and a first stop 12. The clamp body 11 is fitted onto a first component, and the first stop 12 is connected to the clamp body 11. The retaining ring 2 includes a ring body 21 and a second stop 22. The ring body 21 is fitted onto a second component, and the second stop 22 is connected to the ring body 21 and positioned opposite to the first stop 12. The ejection mechanism 3 abuts against the two stops at both ends. When extended, it pushes the stops away from each other, causing the drum clamp 1 and the retaining ring 2 to rotate in opposite directions.

[0029] The clamp body 11 refers to a ring-shaped structural component, which can be implemented as a split, detachable ring segment 111, used to wrap and fix the first component to be disassembled. The first stop 12 refers to a protruding structure located on the outer periphery of the clamp body 11, which can be a welded or bolted metal block, used to transmit the thrust of the ejection mechanism 3. The ring body 21 refers to a ring-shaped component that mates with the second component, which can be a threaded metal ring, used to form a fixed connection with the second component. The second stop 22 refers to a force-bearing point axially corresponding to the first stop 12, which can be a boss integrally formed with the ring body 21, used to form a counter-acting fulcrum. The ejection mechanism 3 refers to a linearly extendable force-applying device, which can be a hydraulic jack or a mechanical screw jack, used to generate controllable axial thrust.

[0030] For example, after the clamp body 11 and the ring body 21 are respectively fixed to the two parts to be separated, the ejection mechanism 3 initiates the extension process. The ejection end applies an outward pushing force to the first stop 12, while the other end generates a reverse force on the second stop 22. After the two stops are subjected to forces in opposite directions, they drive the clamp body 11 and the ring body 21 connected to each other to generate relative rotational motion. This rotational torque acts directly on the threaded structure at the connection of the parts, and by continuously applying a controllable mechanical force, the locking force is gradually released until the two parts to be separated are loosened, which facilitates subsequent disassembly operations. No manual hammering is required during the process, and the pushing force can be precisely adjusted by the ejection mechanism 3 to avoid overload damage to the parts.

[0031] Understandably, this application achieves mechanized disassembly operations, eliminating the safety hazards associated with manual hammering. The synergistic effect of the drum clamp 1 and the fixing ring 2 ensures that the disassembly force is precisely applied to the target connection point, while the progressive force application of the ejection mechanism 3 avoids impact damage to the components. This structural design effectively solves the technical defects of traditional methods, such as low efficiency and dangerous operation, and provides a reliable technical means for disassembling the separator drum.

[0032] This application further proposes that the clamp body 11 includes two ring segments 111, which are detachably connected, and a first stop 12 is provided on either ring segment 111.

[0033] Here, ring segment 111 refers to a component with an arc-shaped structure, which can be implemented using a semi-circular or nearly semi-circular metal plate. Two ring segments 111 are detachably connected to form a complete ring structure, facilitating separate installation. Detachable connection refers to a connection method that allows the ring segments 111 to be separated and fixed, which can be implemented using bolt connections, snap-fit ​​connections, or hinge connections, allowing for adjustment of the combination of ring segments 111 according to actual installation requirements.

[0034] For example, two ring segments 111 are respectively fitted onto both sides of the first component, and the two ring segments 111 are fixed to form the clamp body 11 by a detachable connection, eliminating the need to fit the integral clamp body 11 into the first component, thereby reducing the installation space requirements. The first stop 12 is provided on either ring segment 111, so that the force of the ejection mechanism 3 can be transmitted to the clamp body 11 through the ring segment 111, thereby driving the drum clamp 1 and the fixed ring 2 to rotate in opposite directions. For example, when the first component is a separator drum, the two ring segments 111 can be installed from both sides of the drum respectively, and then fastened with bolts to form the clamp body 11, avoiding the difficulty of operating the integral clamp in a narrow space.

[0035] This application further proposes that the drum clamp 1 also includes a first lug 13, the first lug 13 is disposed on the outer wall of the clamp body 11, the first stop 12 is disposed on the first lug 13, and the fixing ring 2 also includes a second lug 23, the second lug 23 is disposed on the outer wall of the ring body 21, and the second stop 22 is disposed on the second lug 23.

[0036] The first lug 13 refers to a protruding structure installed on the outer wall of the clamp body 11. It can be achieved by welding or bolting. Alternatively, the first lug 13 can be integrally formed with the clamp body 11. The first lug 13 supports the first stop 12 extending radially outward from the clamp body 11, forming a force-bearing fulcrum away from the axis of the clamp body 11. The second lug 23 refers to a protruding structure installed on the outer wall of the ring body 21, supporting the second stop 22 extending radially outward from the ring body 21, forming a force-bearing fulcrum that is offset from the first stop 12.

[0037] For example, the first lug 13 and the second lug 23 are respectively disposed on the outer walls of the clamp body 11 and the ring body 21. When the two ends of the ejection mechanism 3 abut against the first stop 12 and the second stop 22 respectively, the extension action of the ejection mechanism 3 is converted into a rotational torque on the clamp body 11 and the ring body 21. Since the fulcrum formed by the first lug 13 and the second lug 23 is farther from the rotation axis of the clamp body 11 and the ring body 21, the rotational torque is significantly amplified under the same ejection force, thereby reducing the impact force required for manual hammering.

[0038] This application further proposes that the width of the first lug 13 gradually decreases in the direction away from the clamp body 11, and optionally, the width of the second lug 23 gradually decreases in the direction away from the ring body 21.

[0039] The first lug 13 and the second lug 23 have a three-dimensional structure with a continuously tapering cross-section. Specifically, this can be achieved by using a triangular plate-like structure with a top width smaller than a bottom width, and its sidewalls forming an inclined force-bearing surface. The axial extension direction of the triangular plate-like structure forms an angle with the force-applying direction of the ejector mechanism 3.

[0040] For example, when the ejection mechanism 3 extends, the first lug 13 and the second lug 23 decompose the ejection force on the first stop 12 and the second stop 22 into a normal force perpendicular to the connecting surface and a tangential force extending along the connecting surface. The normal force is uniformly transmitted to the clamp body 11 and the ring body 21 through a continuously tapered cross section, avoiding plastic deformation caused by local stress concentration. The tangential force acts on the clamp body 11 and the ring body 21 along the extension direction of the triangular plate, forming a stable reverse torque to drive the drum clamp 1 to rotate and separate from the fixed ring 2. The wider cross-sectional design of the triangular plate at the bottom increases the contact area with the clamp body 11 or the ring body 21, improving the overall bending stiffness of the structure.

[0041] This application further proposes that the drum clamp 1 also includes a first support plate 14, which is disposed on the side of the first stop 12 away from the second stop 22 and connected to the first lug 13. The fixing ring 2 also includes a second support plate 24, which is disposed on the side of the second stop 22 away from the first stop 12 and connected to the second lug 23.

[0042] The first support plate 14 refers to a plate-like structure located outside the first stop 12. Specifically, it can be implemented by welding a triangular metal plate between the first lug 13 and the clamp body 11, and is used to disperse the reverse force applied by the ejection mechanism 3. The second support plate 24 refers to a plate-like structure located outside the second stop 22. Specifically, it can be implemented by welding a triangular metal plate between the second lug 23 and the ring body 21, and is used to counteract the reverse force generated when the ejection mechanism 3 extends.

[0043] For example, the first support plate 14 and the first stop 12 form a T-shaped connection structure, so that the first support plate 14 provides support on the back of the first stop 12, which can effectively improve the stopping effect of the first stop 12 and prevent the first stop 12 from bending and deforming. Similarly, the second support plate 24 and the second stop 22 form a T-shaped connection structure to prevent the two stops from bending and deforming. When the ejection mechanism 3 extends, the first support plate 14 and the second support plate 24 provide opposite support to the first stop 12 and the second stop 22 respectively, avoiding bending and deformation of the root of the stop due to unilateral force.

[0044] This application further proposes that at least one of the first support plate 14 and the second support plate 24 is configured as a triangular plate. The three-sided structure of the triangular plate forms a stable geometric support frame, such that the axial force applied by the ejection mechanism 3 is transmitted along the sides of the triangular plate to the lug connection area.

[0045] This application further proposes to provide an insertion hole 112 on the outer peripheral surface of the fixture body 11, the insertion hole 112 being used for connection with the first component.

[0046] For example, when the clamp body 11 is fitted onto the first component, the insertion hole 112 is aligned with a pre-set threaded hole or positioning groove on the surface of the first component, and a fastener is inserted to form a rigid connection between the clamp body 11 and the first component. During disassembly, the torsional force applied by the ejection mechanism 3 is transmitted to the first component through the cooperation of the insertion hole 112 and the fastener, preventing relative sliding between the clamp body 11 and the first component. For example, the insertion holes 112 can be multiple and evenly distributed circumferentially, with a bolt installed in each insertion hole 112 and threadedly connected to the first component, thereby forming a stable multi-point fixing structure.

[0047] This application further proposes that the outer peripheral surface of the clamp body 11 is provided with a plurality of insertion holes 112, and the plurality of insertion holes 112 are arranged at intervals along the circumference of the clamp body 11.

[0048] For example, multiple insertion holes 112 on the outer circumferential surface of the clamp body 11 are distributed circumferentially, allowing the operator to select insertion holes 112 at different positions for connection and fixation according to the structural characteristics of the first component. When the disassembly tool is connected to the first component, multiple insertion holes 112 are simultaneously inserted into the fixing member, forming multi-point constraints and dispersing the axial tensile force and torsional stress generated during disassembly. The circumferentially spaced distribution of the insertion holes 112 makes the force directions of each connection point complementary, avoiding deformation or breakage of the clamp body 11 due to concentrated force on a single insertion hole 112. When disassembling first components of different sizes, the corresponding insertion holes 112 can be selected for matching installation, thereby improving the versatility of the tool.

[0049] This application further proposes that the fixing ring 2 has a fixing hole 25, which is used to connect with the second component.

[0050] The fixing hole 25 refers to a through hole structure formed on the ring body 21, which forms a rigid connection with the corresponding structure of the second component through a matching bolt, pin, or positioning pin. For example, when the fixing ring 2 is locked to the second component through the fixing hole 25, the fixing hole 25 forms a mating relationship with a pre-set threaded hole or positioning groove on the surface of the second component. During the extension of the ejection mechanism 3, the axial force borne by the second stop 22 is transmitted to the connection point of the second component through the fixing hole 25, keeping the fixing ring 2 and the second component in a coaxial positioning state. In some specific embodiments, the fixing hole 25 can be set as two symmetrically distributed threaded holes, and the connection rigidity is enhanced by a double-bolt fastening method.

[0051] This application further proposes that the ejector mechanism 3 is a jack.

[0052] The jack refers to a device that generates linear thrust using hydraulic or mechanical principles. Specifically, it can be a manual hydraulic jack or an electric screw jack, with the extension and retraction of the jack rod achieved by operating a handle or a motor. Specifically, this jack is a thin-type jack to facilitate installation between the first stop 12 and the second stop 22. In the disassembly tool, the jack is installed between the drum clamp 1 and the fixing ring 2, with its two ends abutting against the first stop 12 and the second stop 22 respectively. By extending the jack rod, a reverse force is generated, converting the impact force of traditional manual striking into a controllable continuous thrust.

[0053] For example, when the jack is activated, the push rod extends axially, pushing the first stop 12 and the second stop 22 away from each other. Since the drum clamp 1 and the retaining ring 2 are respectively fitted onto the first and second components to be disassembled, the reverse thrust forces them to rotate in opposite directions, thereby loosening the threaded connection.

[0054] In one embodiment, this disassembly tool is used in a special tool for separators, such as during the overhaul of a 30-ton separator. Two people install the disassembly tool, use four bolts to fix the drum clamp 1 to the separator drum, use six pins to insert into the insertion hole 112 to lock the slag discharge port of the drum, install the fixing ring 2 and connect the fixing ring 2 to the drum lock with four screws. When installing, pay attention to the distance between the first stop 12 and the second stop 22. Install the jack between the first stop 12 and the second stop 22. One person can complete the disassembly and separation of the drum and the lock by applying pressure to the jack. It is efficient and safe.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
