Description

Technical Field

[0001] This utility model relates to the field of flipping tooling technology, specifically to a flange cover quick flipping device. Background Technology

[0002] As manhole covers for pressure vessels, flange covers bear a critical sealing responsibility. The processing requirements for their sealing grooves are extremely stringent; the processed sealing strips must remain in their original state, as damage is difficult to repair. Previously, flange cover flipping relied on a crane with magnets and manual operation, which was not only highly dangerous but also extremely inefficient. To overcome this challenge, those skilled in the art have continuously explored solutions. For example, the flange processing and flipping mechanism disclosed in Chinese Patent Publication No. CN222360167U uses a hydraulic cylinder to control the extension and retraction of a telescopic rod to replace manual labor. However, this solution still has shortcomings: the impact force when the flange cover lands is large, easily damaging the sealing strips and affecting product quality; it cannot effectively buffer the impact force when the lifting tools are released and the flange cover falls, causing equipment damage or personnel injury; and the overall tooling cost is too high, and the structure is too complex. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a flange cover quick flipping device.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A flange cover quick-turning device includes a turning platform, and a turning mechanism, a support mechanism, a drive mechanism, and a buffer mechanism disposed below the turning platform, wherein:

[0006] The tilting platform is disc-shaped and its size matches that of the flange cover. A rubber pad is provided on its surface. Tilting shafts that cooperate with the tilting mechanism are provided on both sides of the platform. A hinge seat that cooperates with the drive mechanism is provided on one side of the bottom of the platform. An arc-shaped baffle is provided at the front edge of the tilting platform corresponding to the hinge seat.

[0007] The tilting mechanism includes two hinged supports, which are respectively hinged to the left and right sides of the tilting platform via hinge shafts.

[0008] The support mechanism includes a rear panel support column, the top of which is provided with a top buffer pad, which abuts against the rear edge of the tilting platform;

[0009] The drive mechanism includes a hydraulic jack, the top of which is hinged to the tilting platform via a hinge seat, and the lower end of which is tilted backward and installed on the lower part of the rear baffle support.

[0010] The buffer mechanism includes a disc-shaped flip-over buffer pad whose size matches that of the flange cover and is located at the point where the flange cover falls when the flip-over platform rotates 90°.

[0011] This technical solution utilizes a specialized tooling for flipping the flange cover, offering simple operation, fast flipping speed, low labor intensity, and a high safety factor. Specifically, the flipping platform uses hydraulic jacks for unidirectional flipping, ensuring a slow and stable landing and protecting the flange cover's sealing strips from damage. When the platform is horizontal, a rear baffle support provides a limit, preventing it from falling backward and injuring workers. In addition to the rubber pads on the platform surface for cushioning, a top buffer pad is added to the rear baffle support to absorb the impact force caused by the lifting tools releasing the flange cover. When the platform is vertical, a baffle prevents excessive downward sliding during tilting, and the flipping buffer pad mitigates the impact force caused by the flange cover's weight during inertial descent. The entire device has a low cost and is suitable for widespread adoption.

[0012] In addition, the flange cover quick-turning device proposed above according to this utility model may also have the following additional technical features:

[0013] According to one embodiment of the present invention, the flange cover quick-turning device further includes a device base, which is rectangular in shape. A turning buffer pad is provided on its front side, a rear baffle support and a hydraulic jack are provided on its rear side, and hinged brackets are provided on its left and right sides. A motor operating platform is extended on its outer side, and the motor operating platform is connected to the hydraulic jack through an oil supply pipe.

[0014] In this technical solution, the device base is located below the entire device, which integrates the upper flipping platform, flipping mechanism, support mechanism, drive mechanism and buffer mechanism into a complete whole.

[0015] According to one embodiment of the present invention, the motor control panel is further provided with a switch button, a flip button and a return button, which control the start, stop, flip and return actions of the hydraulic jack respectively.

[0016] In this technical solution, the switch button controls the start and stop of the hydraulic jack, preparing for the flange cover to be flipped; the flip button controls the flipping of the hydraulic jack, indirectly controlling the flipping platform to switch from a horizontal state to a vertical state; the return button controls the return of the hydraulic jack, indirectly controlling the flipping platform to switch from a vertical state to a horizontal state.

[0017] According to one embodiment of the present invention, the hydraulic jack is raised to the extended state, and the rear edge of the tilting platform abuts against the top buffer pad of the rear baffle support, at which time the tilting platform is in a horizontal state.

[0018] In this technical solution, the tilting platform is only stable when the flange cover is hoisted and placed on the rubber pad, thus preventing it from tipping over or tilting backward. Therefore, the tilting platform is kept in a horizontal position only with the combined action of two hinged supports, a rear baffle support, and a hydraulic jack.

[0019] According to one embodiment of the present invention, a flange cover is placed above the tilting platform by a lifting mechanism. The hydraulic jack gradually retracts, the rear edge of the tilting platform moves away from the top buffer pad, and the front edge of the tilting platform is temporarily blocked by a baffle until the hydraulic jack retracts to its shortest state. At this time, the tilting platform is in a vertical state, and the flange cover tilts downward with inertia and falls onto the tilting buffer pad located at the landing point.

[0020] In this technical solution, the hydraulic jack retracts slowly to avoid the flange cover falling too quickly and becoming uncontrollable, which could cause seal damage or personal injury.

[0021] According to one embodiment of the present invention, the top cushioning pad, the rubber pad, and the flipping cushioning pad are all made of rubber.

[0022] In this technical solution, the rubber material has high elasticity, heat resistance, wear resistance and solvent resistance; when replacement is needed, it can be disassembled and replaced periodically.

[0023] Compared with the prior art, this utility model has the following advantages:

[0024] (1) The flange cover is slowly rotated in one direction by hydraulic jack to ensure that it lands smoothly and avoids damage to the sealing strip. At the same time, the rear baffle support and baffle are used to prevent accidental damage or excessive sliding. Combined with rubber pads and buffer pads, the impact force is effectively absorbed to improve operational safety.

[0025] (2) The device has a simple structure and low manufacturing cost. Each buffer component (such as rubber pad and flip buffer pad) can be disassembled and replaced, making maintenance convenient and suitable for large-scale promotion and application. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figure 1 As shown, this embodiment provides a flange cover quick-turning device, including a turning platform 4, and a turning mechanism, a support mechanism, a driving mechanism, and a buffer mechanism disposed below the turning platform 4, wherein:

[0031] The flipping platform 4 is set in a disc shape, and its size matches the size of the flange cover. A rubber pad 5 is set on its surface. Flipping shafts 7 that cooperate with the flipping mechanism are set on both sides of it. A hinge seat that cooperates with the drive mechanism is set on one side of its bottom. An arc-shaped baffle 6 is set at the front edge of the flipping platform 4 corresponding to the top of the hinge seat.

[0032] The flipping mechanism includes two hinged brackets 10, which are respectively hinged to the left and right sides of the flipping platform 4 via hinge shafts.

[0033] The support mechanism includes a rear baffle pillar 2, and a top buffer pad 3 is provided on the top of the rear baffle pillar 2. The top buffer pad 3 abuts against the rear edge of the tilting platform 4.

[0034] The drive mechanism includes a hydraulic jack 9, the top of which is hinged to the tilting platform 4 via a hinge seat, and the lower end of the hydraulic jack 9 is tilted backward and installed on the lower part of the rear baffle support 2.

[0035] The buffer mechanism includes a disc-shaped flip-up buffer pad 8, the size of which matches the size of the flange cover, and is located at the landing point of the flange cover when the flip-up platform 4 rotates 90°.

[0036] This technical solution utilizes a specialized tooling for flipping the flange cover, offering simple operation, fast flipping speed, low labor intensity, and a high safety factor. Specifically, the flipping platform 4 is unidirectionally flipped using hydraulic jacks 9, and the flipping process allows for a slow and stable landing, ensuring the flange cover's sealing strips are not damaged. When the flipping platform 4 is horizontal, the rear baffle support 2 provides a limit, preventing it from falling backward and hitting workers. In addition to the rubber pads 5 on the surface of the flipping platform 4 for cushioning, a top buffer pad 3 is added to the top of the rear baffle support 2 to absorb the impact force caused by the lifting tools releasing the flange cover. When the flipping platform 4 is vertical, a baffle 6 prevents excessive downward sliding during tilting, and a flipping buffer pad 8 mitigates the impact force caused by the excessive weight of the flange cover during inertial descent. The entire device has a low cost and is suitable for widespread adoption.

[0037] In addition, the flange cover quick-turning device proposed above according to this utility model may also have the following additional technical features:

[0038] According to one embodiment of the present invention, the flange cover quick flipping device further includes a device base 1, which is rectangular in shape. A flipping buffer pad 8 is provided on its front side, a rear baffle support 2 and a hydraulic jack 9 are provided on its rear side, and hinged brackets 10 are provided on its left and right sides. A motor operating platform 12 is extended on its outer side, and the motor operating platform 12 is connected to the hydraulic jack 9 through an oil supply pipe 11.

[0039] In this technical solution, the device base 1 is located below the entire device, which integrates the upper flipping platform 4, flipping mechanism, support mechanism, drive mechanism and buffer mechanism into a complete whole.

[0040] According to one embodiment of the present invention, the motor control panel 12 is further provided with a switch button 13, a flip button 14 and a return button 15, which respectively control the start, stop, flip and return actions of the hydraulic jack 9.

[0041] In this technical solution, the switch button 13 controls the start and stop of the hydraulic jack 9 to prepare for the flipping of the flange cover; the flipping button 14 controls the flipping of the hydraulic jack 9, indirectly controlling the flipping platform 4 to switch from a horizontal state to a vertical state; the return button 15 controls the return of the hydraulic jack 9, indirectly controlling the flipping platform 4 to switch from a vertical state to a horizontal state.

[0042] According to one embodiment of the present invention, the hydraulic jack 9 is raised to the extended state, and the rear edge of the tilting platform 4 abuts against the top buffer pad 3 of the rear baffle support 2. At this time, the tilting platform 4 is in a horizontal state.

[0043] In this technical solution, when the tilting platform 4 is in a horizontal state, it can only be stabilized when the flange cover is hoisted and placed on the rubber pad 5 to avoid tipping over or tilting backward; therefore, the tilting platform 4 is in a horizontal state only under the combined action of two hinged brackets 10, one rear baffle support column 2 and one hydraulic jack 9.

[0044] According to one embodiment of the present invention, a flange cover is placed above the tilting platform 4 by a lifting mechanism. The hydraulic jack 9 gradually retracts, and the rear edge of the tilting platform 4 moves away from the top buffer pad 3. The front edge of the tilting platform 4 is temporarily blocked by the baffle 6 until the hydraulic jack 9 retracts to its shortest state. At this time, the tilting platform 4 is in a vertical state, and the flange cover tilts downward with inertia and falls onto the tilting buffer pad 8 located at the landing point.

[0045] In this technical solution, the retraction of the hydraulic jack 9 is carried out slowly to avoid the flange cover falling too quickly and becoming uncontrollable, which could cause seal damage or personal injury.

[0046] According to one embodiment of the present invention, the top buffer pad 3, the rubber pad 5, and the flip buffer pad 8 are all made of rubber.

[0047] In this technical solution, the rubber material has high elasticity, heat resistance, wear resistance and solvent resistance; when replacement is needed, it can be disassembled and replaced periodically.

[0048] The usage process of the above embodiments is as follows:

[0049] First, adjust the device to a horizontal position to ensure the tilting platform 4 is stable, with the top buffer pad 3 of the rear baffle support 2 in contact with it, preparing for hoisting. Next, workers use hoisting tools to lift the flange cover and place it horizontally in the center of the tilting platform 4, ensuring the flange center is aligned with the tilting baffle 6 to prevent deviation during tilting. Then, activate the switch button 13 and the tilting button 14. The motor drives the hydraulic jack 9 through the hydraulic oil pipe 11, pushing the tilting platform 4 to slowly tilt 90° around the hinge axis. During the tilting process, the tilting baffle 6 blocks the flange cover to prevent it from sliding down too quickly until the flange cover lands smoothly on the rubber buffer pad on the ground. Finally, operate the return button 15, the hydraulic jack 9 retracts, and the tilting platform 4, supported by the hinge bracket 10 and the rear baffle support 2, slowly returns to a horizontal position, aligning with the top buffer pad 3, completing the entire tilting operation.

[0050] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, it is not limited thereto. Various equivalent modifications or substitutions can be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and essence of the present invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the scope of the claims.
