Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, specifically relating to a hydraulic lifting and demolding device. Background Technology

[0002] Precast bridge decks for high-speed railways are one of the key technologies in modern high-speed railway bridge engineering. Their core lies in achieving efficient, environmentally friendly, and high-quality construction goals through factory production and on-site assembly.

[0003] The components of prefabricated bridge decks for high-speed railways include protective walls, vertical walls, side walls, bottom plates, and cable trough covers. Their overall structure exhibits irregular and diverse characteristics, which poses many challenges to the demolding process.

[0004] Currently, the industry standard for demolding prefabricated bridge decks for high-speed railways is to lift and demold them directly from the mold. However, due to the irregularity of the overall structure of the bridge deck, its center of gravity is biased towards the center. In this case, it is difficult for the components to detach from the mold synchronously during lifting, which can easily lead to collisions and damage to the components, severely affecting their appearance quality. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic lifting demolding device, which solves the technical problem in the prior art that it is difficult to separate the prefabricated bridge deck of high-speed railway from the mold synchronously during demolding, and that it is easy to be bumped and damaged.

[0010] A translation beam is arranged on the top surface of the supporting beam and parallel to the supporting beam, and its length is greater than the length of the supporting beam;

[0011] A connecting rod is provided at one end of the translation beam and is hinged to the drive end of the translation cylinder;

[0013] The structure of this application is reasonable and compact. It provides a stable support foundation through the lifting base, and the cooperation between the support beam and the translation beam ensures smooth and precise movement. The translation cylinder drives the translation beam to adjust the lifting position flexibly and precisely, and the connecting rod ensures smooth power transmission. Finally, the lifting cylinder generates lifting force as needed to complete demolding.

[0017] Preferably, a limiting protrusion is formed on the bottom surface of the translation beam, and a limiting annular groove is formed on the outer circumference of the supporting roller, the limiting annular groove being adapted to the limiting protrusion; by adopting this solution, the movement of the translation beam is guided and limited, preventing it from deviating or swaying, ensuring the stability and accuracy of the movement of the translation beam, thereby ensuring the smooth demolding operation, improving the stability of the device and the demolding quality.

[0018] Preferably, it includes:

[0019] A bearing pad is provided between the lifting cylinder and the translation beam;

[0020] A positioning sleeve is placed on the top surface of the bearing pad and fitted onto the lifting cylinder. This design serves to transmit and disperse the lifting force, reduce stress concentration, improve structural stability, determine the installation position of the lifting cylinder, and also acts as a guide to limit the radial sway of the lifting cylinder, making the movement more stable and reliable, and ensuring the smooth demolding process.

[0021] Preferably, the positioning sleeve has a through hole on its outer side; this design serves as a channel for connecting the control system to the lifting cylinder.

[0022] Preferably, the lifting platform includes:

[0023] Base plate;

[0024] The first vertical beam is disposed between the supporting horizontal beam and the base plate;

[0025] The second vertical beam is located on the top surface of the base plate and is spaced apart from the first vertical beam.

[0026] Two supporting vertical plates are respectively located on both sides of the second vertical beam and connected to the supporting horizontal beam;

[0027] One end of the translation cylinder is installed on the outside of the first vertical beam, and the other end is hinged to the connecting support rod and located between the two supporting vertical plates.

[0028] Preferably, the lifting platform includes:

[0029] A reinforcing plate is installed between the second vertical beam and the base plate. This design effectively enhances the strength and rigidity of the connection area, reduces the risk of deformation or even damage to the connection area during long-term stress, further improves the overall stability and reliability, and extends the service life.

[0030] Preferably, the supporting crossbeam, the translational crossbeam, the first vertical beam, and the second vertical beam are all rectangular tubes; this design facilitates processing and manufacturing, reduces production costs, has good bending and torsional resistance, ensuring structural stability, is hollow inside, which reduces its weight while ensuring strength, and has a flat surface, which facilitates connection and fixation with other components.

Therefore, they should not be construed as limitations on this utility model.

[0047] Furthermore, the terms "first" and "second" 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. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

[0048] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0049] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0050] Example:

[0051] like Figure 1 As shown in the embodiment of this application, a hydraulic lifting demolding device is disclosed for lifting the support shaft, so that the support shaft lifts the prefabricated bridge deck of high-speed rail to detach from the mold. It has the advantages of synchronous detachment, less collision with the mold, avoiding damage to the components, and ensuring the appearance quality. Its structure includes: lifting base 1, support beam 2, translation cylinder 3, translation beam 4, connecting support rod 5 and lifting cylinder 6.

[0052] The lifting machine base 1 is installed at the demolding station and is the basic support component of the entire device.

[0053] The support beam 2 is installed on the top of the lifting machine base 1 to provide a support base for the translation beam 4.

[0054] The translation cylinder 3 is installed on the lifting machine base 1 and located below the support beam 2 to improve the structural compactness. Its extension and retraction direction is the same as the axis of the support beam 2. It is used to provide power for the movement of the translation beam 4. The lifting cylinder 6 is sent to the mold support shaft position by retracting the cylinder, and the lifting cylinder 6 is brought back to its original position by raising the cylinder, so as to avoid affecting the mold's movement on the production line.

[0055] The translation beam 4 is arranged on the top surface of the support beam 2 to support the lifting cylinder 6 and drive the lifting cylinder 6 to translate. It is set parallel to the support beam 2 to avoid instability such as offset and swaying during the movement of the translation beam 4, ensuring the stability of the operation. Its length is greater than that of the support beam 2, which facilitates the transmission connection with the translation cylinder 3.

[0056] The connecting rod 5 is located at one end of the translation beam 4 and is hinged to the drive end of the translation cylinder 3. It is used to drive the translation beam 4 by the translation cylinder 3. Through the hinge, it can adapt to the small deviations and deformations during the operation of the device, and ensure the smoothness and reliability of the movement of the translation beam 4.

[0057] Preferably, the connecting rod 5 has two rods, which are respectively hinged to both sides of the driving end of the translation cylinder 3. This can enhance the stability of force transmission, ensure the balanced force on the translation beam 4, and achieve smooth and precise power transmission, thereby improving the anti-interference ability of the device.

[0058] The lifting cylinder 6 is installed on the top surface of the other end of the translation beam 4 to realize the lifting and demolding function.

[0059] This utility model has a reasonable and compact structure. The lifting base 1 provides a stable support foundation, and the cooperation between the support beam 2 and the translation beam 4 ensures smooth and precise movement. The translation cylinder 3 drives the translation beam 4 to adjust the lifting position flexibly and precisely. The connecting rod 5 ensures smooth power transmission. Finally, the lifting cylinder 6 generates lifting force as needed to complete demolding. By utilizing the coordinated work of each component, it achieves efficient, precise and reliable lifting and demolding functions, so that the bridge deck can be separated from the mold synchronously during demolding, and it is not easy to collide with the mold, thereby avoiding damage to the components and ensuring the appearance quality of the components.

[0060] In some embodiments, such as Figure 1 and Figure 2 As shown, it also includes:

[0061] Multiple support rollers 7 are rotatably mounted on the top surface of the support beam 2 and are spaced apart along the axial direction of the support beam 2, thus supporting the translation beam 4.

[0062] For example, two support rollers 7 are provided and are respectively arranged at both ends of the support beam 2 to support the translation beam 4 at both ends.

[0063] The above-mentioned configuration can significantly reduce the friction between the translation beam 4 and the support beam 2, enabling the translation beam 4 to move more easily and smoothly, and reducing wear between components, thereby improving the service life and working efficiency of the device.

[0064] Based on the above embodiments, such as Figure 2 As shown, a limiting protrusion 41 is formed on the bottom surface of the translation beam 4, and a limiting annular groove 71 is opened on the outer periphery of the supporting roller 7. The limiting annular groove 71 is adapted to the limiting protrusion 41.

[0065] During the movement of the translation beam 4, the limiting protrusion 41 slides within the limiting ring groove 71. At this time, due to the constraint effect of the limiting ring groove 71 on the limiting protrusion 41, the translation beam 4 can be prevented from shifting laterally in the horizontal direction, ensuring that the translation beam 4 always moves stably along the axis of the supporting beam 2.

[0066] By cooperating with the limiting ring groove 71 and the limiting protrusion 41, the movement of the translation beam 4 is guided and limited, preventing it from deviating or shaking. This ensures the stability and accuracy of the movement of the translation beam 4, thereby guaranteeing the smooth demolding operation and improving the stability of the device and the quality of demolding.

[0067] In some embodiments, such as Figure 1 and Figure 2 As shown, it includes:

[0068] The bearing pad 8 is located between the lifting cylinder 6 and the translation beam 4. It plays a role in transmitting and dispersing the lifting force generated by the lifting cylinder 6, thereby reducing stress concentration and improving structural stability.

[0069] The positioning sleeve 9 is located on the top surface of the bearing pad 8 and is fitted onto the lifting cylinder 6. It can accurately determine the installation position of the lifting cylinder 6, ensure that the axis of the lifting cylinder 6 is perpendicular to the axis of the translation beam 4, and also play a guiding role, limiting the swaying of the lifting cylinder 6 in the radial direction, making the movement of the lifting cylinder 6 more stable and reliable, and ensuring the smooth progress of the demolding process.

[0070] Based on the above embodiments, such as Figure 1 and Figure 2 As shown, the outer side of the positioning sleeve 9 has a through hole 91, which is used as a channel for connecting the control system to the lifting cylinder 6.

[0071] In some embodiments, such as Figure 1 and Figure 2 As shown, the lifting platform 1 includes: a base plate 11, a first vertical beam 12, a second vertical beam 13, and two supporting vertical plates 14, specifically configured as follows:

[0072] Base plate 11 serves as the basic support component;

[0073] The first vertical beam 12 is located between the supporting horizontal beam 2 and the base plate 11. It is made of metal profile and is preferably fixed by welding to ensure a firm connection.

[0074] The second vertical beam 13 is located on the top surface of the base plate 11 and is spaced apart from the first vertical beam 12. It is made of metal profile and is connected in the same way as the first vertical beam 12 to ensure the stability of the connection.

[0075] Two supporting vertical plates 14 are respectively located on both sides of the second vertical beam 13 and connected to the supporting horizontal beam 2. Their shape is preferably rectangular, and they are fixed to both sides of the supporting horizontal beam 2 by welding to ensure the tightness of the connection.

[0076] One end of the translation cylinder 3 is installed on the outside of the first vertical beam 12, and the other end is hinged to the connecting support rod 5 and located between the two supporting vertical plates 14. This arrangement ensures both the stability of the fixation and the compactness of the structure.

[0077] Through the above-mentioned further design of the lifting base 1, a stable support frame is formed, which enhances the structural strength and resistance to deformation, and also creates installation space for the translation cylinder 3, thereby improving the overall structural compactness and operational reliability of the device.

[0078] Based on the above embodiments, such as Figure 2 As shown, the lifting base 1 includes a reinforcing plate 15, which is disposed between the second vertical beam 13 and the base plate 11. This effectively enhances the strength and rigidity of the connection area between the two, reduces the risk of deformation or even damage to the connection area during long-term stress, further improves the overall stability and reliability, and extends the service life.

[0079] In some embodiments, such as Figure 1 and Figure 2 As shown, the supporting beam 2, the translation beam 4, the first vertical beam 12, and the second vertical beam 13 are all rectangular tubes.

[0080] The rectangular tube's regular structure facilitates processing and manufacturing, reducing production costs; it possesses excellent bending and torsional resistance, effectively withstanding various complex forces and ensuring structural stability; its hollow interior reduces its weight while maintaining strength, facilitating installation, movement, and operation; and its smooth surface makes it easy to connect and fix with other components, improving assembly accuracy and reliability.

[0081] The detailed operation process of the above technical solution is as follows:

[0082] I. For example Figure 3 As shown, the mold moves to the demolding station, at which point the end and side molds are opened manually to meet the demolding space requirements;

[0083] II. Figure 4 As shown, the translation cylinder 3 retracts, thereby driving the translation beam 4 to move through the connecting rod 5 until the lifting cylinder 6 is sent directly below the support shaft of the mold.

[0084] III. Figure 5 As shown, the lifting cylinder 6 extends to lift the support shaft, thereby causing the support shaft to lift the prefabricated bridge deck of the high-speed rail out of the mold.

[0085] IV. Figure 6 As shown, a special lifting tool lifts the prefabricated bridge deck of the high-speed railway to complete the demolding.

[0086] V. For example Figure 7 As shown, the lifting cylinder 6 retracts, and then the translation cylinder 3 extends, thereby sending the lifting cylinder 6 back to its original position;

[0087] 6. The mold moves away from the demolding station and continues to the next process.

[0088] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
