Abstract
Description
Technical Field
[0001] This utility model belongs to the field of precast panel technology, specifically relating to a universal flipping machine for precast assembly bridge panels. Background Technology
[0002] Precast bridge slabs are crucial components in modern bridge construction. For example, precast assembled bridge decks for high-speed railways are a key technology in modern high-speed railway bridge engineering. Their core lies in achieving efficient, environmentally friendly, and high-quality construction through factory production and on-site assembly. Precast assembled bridge decks for high-speed railways include protective walls, vertical walls, side walls, base slabs, and cable trough covers. Protective walls and side walls vary in size and specifications across projects; therefore, the versatility of production equipment is highly demanding.
[0003] In the casting process of prefabricated bridge decks for high-speed railways, the decks are typically cast upside down in the mold for ease of forming. That is, the bottom surface of the deck faces upwards within the mold. After casting, the decks need to be flipped over using a turning machine so that the bottom surface faces downwards for easier storage and transportation. Therefore, the turning machine is a key piece of equipment in the production process of prefabricated bridge decks for high-speed railways. However, due to the diverse product specifications, different sizes of turning machines are required, increasing equipment costs. Utility Model Content
[0004] This utility model provides a universal flipping machine for prefabricated bridge decks, which solves the technical problem that existing flipping machines have poor adaptability and can only flip bridge decks of a single specification.
[0005] This utility model includes: a frame;
[0006] A first flipping component, one end of which is hinged to one side of the frame;
[0007] The second flipping component, which is mirrored in shape with the first flipping component, is hinged to the other side of the frame;
[0008] The first abutment is vertically disposed at one end of the first flipping member;
[0009] The second abutment is vertically positioned at one end of the second flipping member;
[0010] A first support member is provided on the top surface of the first flipping member, and the position of the first support member is adjustable;
[0011] The second support member is located on the top surface of the first flipping member, and the height of the second support member is adjustable.
[0012] When the first flipper and the second flipper are both vertical, the first abutment and the second abutment intersect and are located on the same plane.
[0013] This utility model utilizes a first support member and a second support member to compensate for the different height differences between the protective wall and the side wall on the front of the bridge deck, allowing the bridge deck to be placed horizontally on the first flipping member. When the first flipping member is flipped to 90°, the bridge deck is also in a vertical state. Then the second flipping member flips the bridge deck another 90°, flipping the bridge deck from a vertical state to the front, completing the bridge deck flipping operation, so as to facilitate subsequent storage and transportation.
[0014] Furthermore: the first flipping component and the second flipping component are respectively driven by hydraulic cylinders;
[0015] The first and second support members are driven by hydraulic cylinders or pneumatic cylinders. The advantages of this step are: since the first and second flipping members need to bear the weight of the bridge deck, and the bridge deck is heavy, the hydraulic cylinder can provide a large thrust to complete the action of the first and second flipping members; while the first and second support members only need to support the bridge deck with their bodies, and do not need to adjust their positions under load, so they can be driven by pneumatic cylinders or hydraulic cylinders.
[0016] Further: the rack includes:
[0017] bottom frame;
[0018] At least two pairs of hinge rods are symmetrically arranged in the middle of the bottom frame;
[0019] A reinforcing rod is provided between the hinge rods. The height of the reinforcing rod is adapted to the height of the first abutment and the second abutment when they are on the same horizontal plane. The beneficial effect of this step is that the reinforcing rod provides a horizontal plane, keeps the first abutment and the second abutment horizontal, and provides support for both.
[0020] Furthermore, the frame is also provided with support rods at the positions corresponding to the outer ends of the first and second flipping parts. The beneficial effect of this step is that the support rods can improve the support force of the first and second flipping parts in a horizontal state, reduce the burden on the hydraulic cylinder, and improve the service life of the hydraulic cylinder.
[0021] Furthermore, a diagonal reinforcing bar is provided between the hinge rod and the bottom frame. The beneficial effect of this step is that it strengthens the structural strength of the hinge rod.
[0022] Furthermore, the end of the second abutment is also provided with a baffle. The beneficial effect of this step is that the baffle can keep the first abutment and the second abutment on the same horizontal plane.
[0023] Furthermore, pads are provided on the top surfaces of the first and second flipping parts, the top surfaces of the first and second supporting parts, and the sides of the first and second abutting parts. The beneficial effect of this step is that the pads play a role in noise reduction and vibration damping.
[0024] The beneficial effects of this utility model are:
[0025] 1. This utility model adapts the height difference between the protective wall and the side wall on the bridge deck of different specifications by adjusting the first support member and the second support member. This allows the bridge deck of different specifications to be in a horizontal state on the first flipping member. This ensures that the first flipping member carrying the bridge deck can be stably in a vertical state after flipping, so that the bridge deck can be smoothly transferred to the second flipping member and thus flipped smoothly.
[0026] 2. This utility model is designed to adapt to the flipping requirements of bridge decks of different specifications, thereby saving on the number of equipment and equipment costs. Attached Figure Description

[0036] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0037] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0038] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.
[0039] Examples of embodiments of this utility model Figures 1-5 As shown, the present invention provides a universal flipping machine for prefabricated bridge decks, which can smoothly flip bridge decks of different specifications by 180°.
[0040] This utility model includes: a frame 1;
[0041] The first flipping component 2, one end of which is hinged to one side of the frame 1;
[0042] The second flipping member 3 is hinged to the other side of the frame 1, mirroring the first flipping member 2;
[0043] The first abutment 4 is vertically disposed at one end of the first flipping member 2, and is at the end close to the hinge point of the first flipping member 2;
[0044] The second abutment 5 is vertically disposed at one end of the second flipping member 3, and is at the end close to the hinge point of the second flipping member 3;
[0045] The first support member 6 is located on the top surface of the first flipping member 2, and the position of the first support member 6 is adjustable.
[0046] The second support member 7 is located on the top surface of the first flipping member 2, and the height of the second support member 7 is adjustable.
[0047] When the first flipper 2 and the second flipper 3 are both vertical, the first abutting member 4 and the second abutting member 5 intersect and are located on the same plane.
[0048] Normally, there is a height difference between the protective wall and the side wall of the bridge deck 8. This height difference can be compensated by the second support member 7. However, when this height difference exceeds the height adjustment range of the second support member 7, the first support member 6 is needed to further compensate for the difference between the height difference and the second support member 7. (See reference...) Figure 1 and Figure 4 ;exist Figure 1 In the middle, the bridge deck 8 can be kept level using only the second support member 7. Figure 4 In order to keep the bridge deck 8 level, the first support member 6 and the second support member 7 need to be used simultaneously. Therefore, the second support member 7 needs to have the ability to adjust its height, and the first support member 6 needs to have the ability to adjust its position and also its height.
[0049] by Figures 1-3 For example, in the use of this utility model, the first step is to flip the second flipping member 3 to a vertical position, while the second abutment member 5 is in a horizontal position. Then, in the second step, when the first flipping member 2 flips to 90°, the bridge panel 8 is also in a vertical position, and the first abutment member 4 is also in a horizontal position, on the same horizontal plane as the second abutment member 5. At this point, the side of the bridge panel 8 simultaneously contacts the first abutment member 4 and the second abutment member 5. Finally, the third step involves using the second flipping member 3 to flip the bridge panel 8 another 90°, turning it from a vertical position to a front view, thus completing the flipping operation of the bridge panel 8 for subsequent storage and transportation. In the above process, the first flipping member 2 and the second flipping member 3 act as a drive, while the first abutment member 4 and the second abutment member 5 act as a positioning element. The second abutment member 5 also acts as a prying element.
[0050] Based on the above technical solution, the first flipping component 2 and the second flipping component 3 are respectively driven by hydraulic cylinders;
[0051] The first support member 6 and the second support member 7 are driven by hydraulic cylinders or pneumatic cylinders. Since the first flipping member 2 and the second flipping member 3 need to bear the huge weight of the bridge deck 8, the hydraulic cylinder can provide a large thrust to complete the action of the first flipping member 2 and the second flipping member 3. The first support member 6 and the second support member 7 only need to support the bridge deck 8 with their bodies and do not need to adjust their positions under load, so they can be pushed by pneumatic cylinders or hydraulic cylinders.
[0052] Based on the above technical solution, the rack 1 includes:
[0053] The bottom frame 11 is assembled by welding together pipes or profiles;
[0054] At least two pairs of hinge rods 12 are symmetrically arranged in the middle of the bottom frame 11, and the top of the hinge rods 12 are respectively hinged to the bottom surface of the first flip member 2 and the second flip member 3.
[0055] The reinforcing rod 13, located between the hinge rods 12, not only strengthens the structural strength of the hinge rods 12, but also allows the height of the reinforcing rod 13 to match the height of the first abutment 4 and the second abutment 5 when they are on the same horizontal plane. The reinforcing rod 13 provides a horizontal plane, keeping the first abutment 4 and the second abutment 5 horizontal, and also provides support for both.
[0056] Based on the above technical solution, the frame 1 is further provided with a support rod 14 at the position corresponding to the outer end of the first flipping member 2 and the second flipping member 3. The support rod 14 can improve the support force of the first flipping member 2 and the second flipping member 3 in the horizontal state, reduce the burden on the hydraulic cylinder, and improve the service life of the hydraulic cylinder.
[0057] Based on the above technical solution, an inclined reinforcing rod 15 is also provided between the hinge rod 12 and the bottom frame 11, which serves to strengthen the structural strength of the hinge rod 12.
[0058] Based on the above technical solution, the end of the second abutment 5 is also provided with a baffle 9; when the second abutment 5 is in a horizontal position first, the baffle 9 corresponds to the position of the first abutment 4 and can prevent the first abutment 4 from continuing to flip downward. The baffle 9 plays the role of keeping the first abutment 4 and the second abutment 5 on the same horizontal plane.
[0059] Based on the above technical solution, pads are provided on the top surfaces of the first flipping member 2 and the second flipping member 3, the top surfaces of the first support member 6 and the second support member 7, and the sides of the first abutting member 4 and the second abutting member 5 facing the bridge deck 8. The pads are generally made of rubber or plastic and can play a role in noise reduction and vibration damping.
[0060] This invention, by setting a first support member 6 and a second support member 7 on the first flipping member 2, can adapt to bridge deck panels 8 with different height differences, allowing one flipping machine to perform flipping operations on bridge deck panels 8 of different specifications, thereby reducing the number of flipping machines and saving equipment costs.
