Description

Technical Field

[0001] This utility model relates to the technical field of sleeper demolding equipment, and in particular to a vibration demolding device for SK-2 double-block sleepers. Background Technology

[0002] As an indispensable key component of railway infrastructure, the production efficiency and quality of railway sleepers directly determine the progress of railway construction and the safety of railway operation. In recent years, with the rapid development of high-speed railway construction, the demand for railway sleepers has been continuously increasing. Against this backdrop, sleeper demolding tables, as an advanced automated production equipment, have received widespread attention and have been widely used. The demolding process in sleeper production is a crucial technical step that directly affects the quality and production efficiency of sleepers. Through continuous improvement and optimization of demolding technology, production efficiency can be significantly improved, production costs can be effectively reduced, and high-quality standards can be ensured for sleepers. With the continuous advancement of technology and the constant changes in production demands, demolding technology will continue to develop and innovate to adapt to higher production standards and ever-growing market demands. In the sleeper manufacturing process, the demolding step plays a vital role, affecting not only production speed but also the final quality of the product. Modern sleeper manufacturers have introduced advanced demolding equipment and technologies, achieving precise control and efficient execution of the demolding process through sophisticated robotic arms, intelligent sensors, and automated control systems. This not only significantly improved production efficiency but also effectively reduced the product defect rate caused by human error, ensuring high-quality output of railway sleepers.

[0003] The SK-2 type double-block sleeper is a key component widely used in railway construction. Its common dimensions are 2400×314×280.5 mm. Compared to other models, the SK-2 is larger in size, capable of withstanding higher loads, ensuring the safety and stability of railway transportation. During casting, the mold opening of the SK-2 type double-block sleeper faces upwards; during demolding, the mold opening faces downwards. Existing sleeper demolding tables mainly rely on a gravity-inertia demolding method. This method separates the sleeper from the mold by raising the sleeper model and utilizing the free-fall acceleration generated by the sleeper's own weight. However, in practical applications, this type of sleeper demolding table may have some shortcomings, which may negatively impact sleeper production efficiency and product quality. For example, the sleeper demolding table needs to remain stable under heavy load impacts, and the main problems in the sleeper demolding process include high demolding resistance and low demolding efficiency. Specifically, the sleeper cannot be demolded solely by its own weight; it needs to overcome multiple resistances to successfully demold. In addition, the design of the demolding table may have defects, such as asynchronous deflation of airbags or uneven demolding platform. These problems will increase the difficulty of demolding and may even lead to damage to the sleepers.

[0004] In addition, the existing sleeper demolding platform is built independently. During demolding, the sleeper and mold need to be hoisted onto the sleeper demolding platform. Since most railway construction adopts large-scale production, the transportation of sleepers and molds is usually carried out by rail. If it is a small batch of mold demolding, a gantry crane can be used to hoist them directly onto the sleeper demolding platform. However, this method is not suitable for the demolding of sleepers in large-scale production. In the actual production process, the applicant considered that if the sleeper demolding platform is connected to the transportation track, it will improve the existing demolding process and greatly improve the demolding efficiency. Therefore, there is an urgent need for a demolding device suitable for rail transportation. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a vibration demolding device for SK-2 double-block sleepers, which can improve the existing sleeper demolding process, reduce demolding resistance, and can be integrated into the transport track to improve the demolding efficiency and product quality of the sleepers.

[0006] The purpose of this utility model is achieved through the following technical solution: a vibration demolding device for SK-2 double-block sleepers, comprising a vibration assembly, a support assembly, and a lifting assembly. The vibration assembly consists of multiple first support seats arranged below the sleepers for supporting the sleepers. Each first support seat has multiple vibration modules installed on one side for vibrating the sleepers. A channel for transporting the track is provided between the first support seats. The support assembly consists of second support seats arranged outside the first support seats for supporting the mold. The second support seats have a positioning surface that contacts the mold. The positioning surface has multiple limiting grooves for limiting the mold. Multiple lifting points are provided in the area where the mold does not contact the second support seats. The lifting assembly consists of multiple lifting modules arranged outside the first support seats for lifting the mold. When lifting the mold, the actuating part of the lifting module presses against the lifting point and drives the mold to move.

[0007] The vibration module consists of a vibration motor and a vibration plate. The vibration motor is mounted on a first support base, and an elastic element is provided on the output end of the vibration motor. The vibration plate is mounted on the elastic element, and the vibration motor drives the vibration plate to reciprocate. The elastic element is a rubber spring, which has large elastic deformation and strong restoring ability. It can absorb the vibration and impact generated by the device, as well as the noise generated by the vibration of the device operation, thereby reducing noise pollution in the working environment.

[0008] Preferably, the first support bases are arranged parallel to each other and independently, which facilitates the arrangement of the passage.

[0009] The lifting module consists of a third support base and a lifting frame. The lifting frame is the moving part of the lifting module. The third support base is arranged on both sides of the transport track. A lifting motor is installed on the third support base. The lifting frame is connected to the output end of the lifting motor. The lifting frame is placed below the mold. The lifting motor drives the lifting frame to perform a reciprocating motion to lift the mold.

[0010] The lifting points are symmetrically distributed on the bottom surface of the mold, which ensures more stable operation of the lifting module when lifting the mold. Preferably, the length of the frame where the mold contacts the second support is greater than the length of the second support. The lifting points can be arranged on the frame that contacts the second support, which facilitates the installation of the support assembly and the lifting assembly.

[0011] Preferably, the limiting groove is the gap between limiting blocks arranged symmetrically or staggeredly on the positioning surface, and the mold frame is placed on the first support base and limited by the limiting groove. It should be noted that when the mold is not completely demolded, the mold will float with the lifting of the sleeper. Therefore, the amplitude of the vibration motor and the height of the limiting block should be selected according to the actual situation to ensure that the mold does not fall out of the limiting groove during vibration demolding.

[0012] After the vibratory motor is started, the vibration force generated by the motor is transmitted between the sleeper and the mold. This vibration force, through the high-frequency vibration of the motor, loosens and separates the contact surface between the sleeper and the mold. The vibration frequency and amplitude of the motor can be adjusted according to specific conditions to ensure optimal separation between the sleeper and the mold. In this way, the sleeper can be effectively separated from the mold, thus completing the sleeper demolding process. By generating high-frequency vibration, the vibratory motor reduces the friction between the sleeper and the mold, making demolding easier. Simultaneously, the use of the vibratory motor makes the demolding process smoother, reducing impact and damage to the sleeper. The vibratory motor provides stable vibration force, helping the concrete sleeper to better detach from the mold during demolding. This vibration demolding method not only improves production efficiency but also significantly enhances product quality, ensuring the shape and dimensional accuracy of the sleeper. The vibration frequency and amplitude of the motor can be precisely adjusted, which is crucial for ensuring the accuracy of sleeper demolding. Appropriate vibration ensures even distribution of the sleeper during demolding, reducing defects and improving the final product's pass rate. This precisely controlled vibration method not only improves production efficiency but also ensures the quality stability of the sleepers, thus giving it a significant advantage in market competition.

[0013] As can be seen, this application provides a channel for the transport track in the vibration component, allowing the entire device to be connected to the transport track. At the same time, a support component and a lifting component are arranged outside the first support base. After demolding, the sleepers fall on the first support base and are lifted and placed in the transport track to continue moving forward. They are transported along a predetermined path to a special inspection area to ensure that their quality meets the standard requirements. After demolding, the mold falls on the second support base and is lifted to an appropriate height by the lifting module to facilitate subsequent handling and processing.

[0014] The beneficial effects of this utility model are: by leaving a channel for the transport track in the vibration component, the entire device is connected to the transport track, and the mold is lifted by the lifting component. During the entire demolding process, the mold and the sleeper do not leave the working range of the transport track, which improves the existing sleeper demolding process. At the same time, multiple sets of vibration modules are set below the vibration component, which reduces demolding resistance and improves the demolding efficiency and product quality of the sleeper.

Detailed Implementation

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1-3As shown, this is the first embodiment of the present solution, a vibration demolding device for SK-2 double-block sleepers, including a vibration assembly 1, a support assembly 2, and a lifting assembly 3. The vibration assembly 1 consists of two first support seats 101 arranged below the sleepers 4 for supporting the sleepers 4. Each first support seat 101 has multiple vibration modules installed on one side for vibrating the sleepers 4. A channel 105 for the passage of the transport rail 6 is provided between the first support seats 101. The support assembly 2 consists of components arranged outside the first support seats 101 for supporting the mold. The mold 5 is composed of a second support base 201, which has a positioning surface that contacts the mold 5. The positioning surface has multiple limiting grooves 202 for limiting the mold 5. Four lifting points are provided on the area where the mold 5 does not contact the second support base 201 (located at the four corners of the two side frames of the mold 5 respectively). The lifting assembly 3 is composed of multiple lifting modules arranged outside the first support base 101 for lifting the mold 5. When lifting the mold 5, the actuating parts of the lifting modules press against the lifting points and drive the mold 5 to move.

[0025] like Figures 4-5 As shown, the vibration module consists of a vibration motor 102 and a vibration plate 103. The vibration motor 102 is mounted on a first support 101, and an elastic element 104 is provided on the output end of the vibration motor 102. The vibration plate 103 is mounted on the elastic element 104, and the vibration motor 102 drives the vibration plate 103 to reciprocate. The first support 101s are arranged parallel to each other and independently. It should be noted that the number of vibration modules is determined based on the contactable area on the SK-2 sleeper. Preferably, the vibration modules are arranged symmetrically along the centerline of the sleeper 4 to ensure uniform force during vibration. Figures 6-7 As shown, the limiting groove 202 is the gap between the limiting blocks 203 that are staggered on the positioning surface. Four limiting blocks 203 for limiting are provided on the positioning surface. The frame of the mold 5 can be limited by inserting into the limiting groove 202.

[0026] The lifting module consists of a third support base 301 and a lifting frame 302. The lifting frame 302 is the moving part of the lifting module. The third support base 301 is arranged on both sides of the transport track 6. A lifting motor 303 is installed on the third support base 301. The lifting frame 302 is connected to the output end of the lifting motor 303. The lifting frame 302 is placed below the mold 5. The lifting motor 303 drives the lifting frame 302 to perform a reciprocating motion to lift the mold 5.

[0027] The first support base 101, the second support base 201, and the third support base 301 are frame structures, welded using channel steel commonly used in railway construction, meeting only the strength requirements. These supports can be directly installed on the foundations on both sides of the transport track 6. The third support base 301 can be either a fixed or movable installation structure (e.g., a traveling device with braking function installed at the bottom of the third support base 301). As long as lifting action is possible, the installation position can be determined according to the actual situation. In this application, a vibration motor with a voltage of six or higher is sufficient, and an amplitude of 4-8mm is adequate for demolding the SK-2 double-block sleeper. During operation, the cast mold 5 and sleeper 4 are transported to the designated location via the transport rail 6 (at this time, the mold 5 has been flipped over, with its opening facing downwards for easy demolding). Then, the mold 5 and sleeper 4 are hoisted onto the first support base 101 by a gantry crane. The frame of the mold 5 is locked in the limiting groove 202 to limit its position. Before the vibration motors 102 located on both sides of the transport rail 6 are started, the sleeper 4 is not in contact with the second support base 201. After the vibration motors 102 are started, the vibrating plate 103 contacts the sleeper 4 and vibrates the sleeper 4. At this time, the sleeper 4 is still not in contact with the second support base 201. After the vibration demolding is completed, the vibration motors 102 are turned off, and the sleeper 4 falls onto the second support base 201 (at this time, the vibration motors 102 fall back, and the vibrating plate 103 separates from the sleeper 4). Therefore, according to the actual use, it is sufficient to ensure that the support height of the second support base 201 is within the amplitude range of the vibration motor 103. This will not be elaborated here. After demolding, the sleeper 4 is lifted and placed on the transport rail 6 to continue moving forward to complete the next process. After demolding, the mold 5 is lifted to an appropriate height by the lifting frame 302 in the lifting assembly (where the lifting frame 302 is slidably mounted on the third support 301, the lifting motor 303 drives the lifting frame 302 to reciprocate, and the third support 301 and the lifting frame 302 adopt a sliding block sliding pair), and then hoisted through the transport rail 6 for subsequent handling and processing.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
