Description

Technical Field

[0001] The utility model relates to the technical field of precast production of double-block sleepers, and more specifically to the technical field of an embedded sleeve installation device. Background Art

[0002] With the advent of the high-speed rail era, the double-block sleeper production line has become increasingly advanced, and the demand for sleepers has also increased significantly. The existing double-block sleeper production line has started to develop towards intelligence, but sleeper quality problems are inevitable. Currently, the quality problems of double-block sleepers include sleeve problems, shoulder cracks, etc. To improve the production quality of sleepers and ensure the product qualification rate, solving the quality problems of double-block sleepers is our primary goal.

[0003] At present, an automated sleeve installation device is used for the embedded sleeves of the intelligent production line of double-block sleepers. From the placement of sleeves, the positioning of sleeve bolts, to the automatic tightening of sleeves, the entire operation process is completed by equipment. Since the installation of the embedded sleeves is realized by mechanization and automation, it is necessary to ensure that all operation steps and supporting equipment conditions meet the ideal state. If the bolt positioning is inaccurate and tilts, it will cause the embedded sleeve to tilt or the sleeve to loosen, ultimately resulting in the tilt or displacement of the product sleeve.

[0004] Specifically, the intelligent production line of double-block sleepers has currently achieved fully automated production, which reduces labor costs and improves production efficiency in the production process. The traditional double-block sleeper production line needs to be equipped with nearly 30 people. Now, with the application of the intelligent production line, the labor has been greatly reduced, and the entire production line only requires 13 people to complete the assembly line operation. However, while being intelligent, it is necessary to meet conditions in all aspects, including the matching of the mold and the equipment. Therefore, while improving production efficiency, there are also some sleeper quality problems, especially the problem of embedded sleeve installation. The existing intelligent production line has the following problems in the technology of embedded sleeve installation:

[0005] 1. The jacking of the embedded sleeve bolts is not in place. A sleeve bolt fixing device is used to jack the bolts at the bottom of the mold that has advanced to this station out of the sleeper mold shell through a fixed wrench extending into the bottom of the mold. In this process, since the sleeve bolts at the bottom of the mold are not in a vertical state, but are prevented from falling to the ground by a baffle added at the bottom of the mold, when the fixed wrench contacts the sleeve bolt and jacks it upward, it is very difficult to ensure that the bolt is jacked vertically upward, resulting in the bolt tilting or even the sleeve bolt not being able to be jacked out of the sleeper mold shell. Furthermore, when installing the sleeve, the sleeve will be loose, tilted, and not firm.

[0006] 2. The vertical and firm installation of the sleeve cannot be guaranteed. Even if a sleeve bolt fixing device is used to jack the bolt out of the sleeper mold shell, it cannot be ensured that each sleeper bolt is vertical and has been jacked in place. Then, manual inspection is required, which reduces the production speed. Summary of the Utility Model

[0007] The purpose of the present utility model is to provide an embedded sleeve installation device to solve the above technical problems. It can ensure the precise positioning of sleeve bolts. A guiding device is installed at each position of the embedded sleeve, so that during the process of bolt jacking, the bolts are ensured not to tilt, are precisely positioned, and are vertically jacked up. It perfectly solves the problem of inaccurate bolt positioning during the embedding of the sleeve.

[0008] The present utility model specifically adopts the following technical solutions to achieve the above purpose:

[0009] The present utility model provides an embedded sleeve installation device, which includes a sleeper mold support, a sleeper mold arranged on the sleeper mold support, an embedded sleeve to be installed in the sleeper mold, a sleeve vibration sieve for screening the embedded sleeve, a sleeve storage table connected to the sleeve vibration sieve, a sleeve placement platform cooperating with the sleeve storage table, a sleeve tightening device arranged above the sleeper mold for tightening the embedded sleeve in the sleeper mold, a bolt fixing device capable of moving and lifting arranged below the sleeper mold, and a sleeve bolt movably arranged on the bolt fixing device. It also includes a guiding device sleeved outside the sleeve bolt.

[0010] Specifically, the function of the embedded sleeve installation device is to first pre-screen and place the embedded sleeves on the sleeve placement platform. After the mold before the sleeper is poured is transported to the embedded sleeve installation device, the placed embedded sleeves are then installed into the mold to ensure the accurate and firm installation of the embedded sleeves.

[0011] The setting of the guiding device can ensure the precise positioning of the sleeved bolts during the installation of the embedded sleeve, the efficient installation of the embedded sleeve, a high qualification rate, greatly improve the quality of the sleeper, achieve the goals of high efficiency, high quality, and high standards in the intelligent production of double-block sleepers, provide a basis for the subsequent intelligent production of double-block sleepers, and lay a direction on the road of continuously improving the intelligent production of double-block sleepers.

[0012] In one embodiment, the guiding device is sleeved outside the sleeve bolt in a form of bottom welding, and the sleeve bolt is slidably arranged in the guiding device. A falling prevention device for preventing the sleeve bolt from falling is arranged at the bottom of the guiding device.

[0013] Specifically, through seamless welding technology, the guiding device is welded to each embedded hole position. During the welding process, it should be ensured that the device does not displace and is precisely positioned.

[0014] First, find the position of each sleeve bolt at the bottom of the mold. Fix the guiding device to the bolt by welding. Place the bolt in the sleeve to ensure that the bolt can move vertically up and down within the sleeve and restrict its lateral displacement. After the installation of the guiding device is completed, finally install the anti-falling device, which is connected to the guiding device to restrict the sleeve bolt from falling after demolding.

[0015] In one embodiment, the guiding device is a guiding sleeve, and the material of the guiding sleeve is steel pipe.

[0016] In one embodiment, the height of the guiding sleeve is 110 mm - 120 mm, the thickness of the guiding sleeve is 2 mm - 3 mm, and the outer diameter of the guiding sleeve is 108 mm - 110 mm.

[0017] Specifically, this guiding device is composed of a circular steel sleeve. Preferably, the dimensions of the steel sleeve are: height 115 mm, outer diameter 108 mm, and thickness 2 mm.

[0018] In one embodiment, the anti-falling device is a baffle welded to the bottom of the guiding device.

[0019] Specifically, the setting of the baffle ensures that when the sleeper mold is demolded and the sleeve bolt is loosened, the bolt will not fall, ensuring that the sleeve bolt is within the embedded sleeve.

[0020] In the existing technical solution, only a baffle is used at the bottom of the mold to restrict the sleeve bolt within the baffle so that it will not fall off. For the present utility model, the baffle at the bottom of the mold needs to be completely removed first to expose the sleeper surface, and then the guiding device is installed. During the removal process, precise cutting should be carried out to avoid deformation of the sleeper shell, resulting in appearance quality problems of the product.

[0021] The above solution is the optimal implementation method. In addition, the installation of the embedded sleeve can also be achieved in other ways, such as using rubber-type embedded bolts. The sleeve bolt is directly fixed at the bottom of the mold, so that the rubber bolt is always outside the sleeper mold shell. When the sleeper is demolded, the bolt does not need to be loosened, and the sleeper is turned over and demolded by relying on its own weight. Although this method can ensure the accurate installation of the bolt and the sleeve, it is not easy to demold, which affects the production efficiency and cannot guarantee the product quality.

[0022] In one embodiment, a plurality of positioning cones are movably arranged on the sleeve placement platform, and a control cylinder is arranged on the sleeve storage platform. The control cylinder drops the embedded sleeve onto each positioning cone on the closed sleeve placement platform;

[0023] It further includes a push-pull oil cylinder capable of adjusting the distance between the sleeve placement platform and the sleeper mold. The push-pull oil cylinder moves the sleeve placement platform to the sleeve grasping position, and a distance adjustment mechanism for adjusting the distance between adjacent two positioning cones is arranged on the sleeve placement platform.

[0024] Specifically, the process of automatically placing the embedded sleeves in advance is as follows:

[0025] S11. Manually place a certain quantity of embedded sleeves into the sleeve vibration sieve.

[0026] S12. Start the sleeve vibration sieve, and the embedded sleeves will be arranged in order by vibration and fall into the sleeve storage table one by one.

[0027] S13. After the storage table is full of sleeves, start the control cylinder to drop all the embedded sleeves onto the positioning cones on the sleeve placement platform after closing.

[0028] S14. Control the push-pull oil cylinder to move the sleeve placement platform to the sleeve grasping position, and start the motor to widen the distance between the closed sleeve placement platforms until it finally matches the distance between the sleeves in the mold.

[0029] S15. Start the sleeve clamping cylinder to clamp the sleeve and wait for the sleeve screwing device at the sleeve installation station to grasp it.

[0030] In one embodiment, the bolt fixing device includes a moving frame below, a hydraulic cylinder driving the moving frame to move, and a lifting cylinder controlling the lifting of the moving frame. The sleeve bolts are fixed on the moving frame, and the lifted sleeve bolts protrude and extend into the sleeper mold.

[0031] In one embodiment, it further includes a lifting cross beam and a moving longitudinal beam fixed on the lifting cross beam. The sleeve screwing device is arranged on the moving longitudinal beam. The sleeve screwing device includes a wrench for grasping the embedded sleeve and a motor driving the wrench to rotate.

[0032] In one embodiment, external threads are provided on the outer wall of the embedded sleeve, and internal threads matching the external threads of the embedded sleeve are provided inside the wrench.

[0033] In one embodiment, during the tightening operation, the wrench with the embedded sleeve cooperates with the sleeve bolt extending into the sleeper mold, and the motor is rotated to tighten the embedded sleeve with the sleeve bolt and fix it on the sleeper mold.

[0034] Specifically, the process of grasping the sleeves on the sleeve placement platform and loading them into the mold is as follows:

[0035] S21. The sleeper mold is in place and positioned. The logistics trolley transports the sleeper mold to the embedded sleeve installation equipment. After being detected by the sensor, the trolley lifting device places the sleeper mold on the sleeper mold support.

[0036] S22. Control the moving beam of the sleeve bolt fixing device under the sleeper mold support through a hydraulic cylinder, move and lift the sleeve bolt fixing device to a fixed position, extend the fixed wrench into the bottom of the mold, and push out the sleeve bolts at the corresponding positions from the sleeper mold shell;

[0037] S23. The oil cylinder controls the moving longitudinal beam to move above the sleeve placement platform, aligning the wrenches of each sleeve screwing device with the embedded sleeves at the corresponding positions;

[0038] S24. Lower the lifting oil cylinders of all sleeve screwing devices so that the wrenches of each device are sleeved on the embedded sleeves at the corresponding positions;

[0039] S25. Start the motor of the sleeve screwing device to rotate forward by a fixed number of turns, and screw the sleeve into the wrench through the thread on the wrench to grab it;

[0040] S26. Loosen the sleeve clamping cylinder;

[0041] S27. Lift the sleeve screwing device that has grabbed the upper embedded sleeve again through the device lifting oil cylinder, and then control the moving oil cylinder to move the longitudinal beam above the sleeper mold;

[0042] S28. Lower the lifting oil cylinders of all sleeve screwing devices again, so that the embedded sleeves in each wrench are lowered and sleeved on the sleeve bolts at the corresponding positions extending into the sleeper mold.

[0043] S29. Start the motor of the sleeve screwing device to rotate forward until all sleeves are tightened and fixed on the sleeper mold with the sleeve bolts;

[0044] S210. Rotate the sleeve screwing motor in the reverse direction by a fixed number of turns to loosen the wrench from the embedded sleeve, ensuring that the sleeve cannot be loosened when the wrench is sent back.

[0045] S211. After all the wrenches of the sleeve screwing devices loosen the embedded sleeves, control the device lifting cylinders to lift all the devices, and at the same time, the fixed sleeve bolt device under the embedded mold descends and moves out from under the sleeper mold.

[0046] S212. Move the transfer cart into the sleeve installation mold station, raise the lifting oil cylinder on the cart, and transport the sleeper mold with the embedded sleeves to the next station for manual inspection to complete the sleeve installation.

[0047] The beneficial effects of the present utility model are as follows:

[0048] 1. The design of the utility model is reasonable. A guiding device is added at the bottom of the original model. During the process of jacking the sleeve bolt, the sleeve bolt can be accurately and vertically jacked into the sleeper mold, ensuring the installation efficiency of the embedded sleeve, improving the production speed, and finally forming qualified products. Compared with the prior art, it has more advantages. In terms of the production efficiency of sleepers, it not only ensures the product quality but also increases the output, and the product qualification rate is extremely high. In terms of materials and energy consumption, the loss rate of the embedded sleeve is reduced, saving the material cost.

[0049] 2. Through the setting of the utility model, the intelligent production line of double-block sleepers is more perfect, improving the production efficiency, greatly increasing the daily output, reducing the construction production cost, and ensuring the product quality. In the case of the prior art, several or even more than a dozen products may be scrapped every day due to sleeve problems. Through the guiding device designed in this solution, the scrap rate of the product embedded sleeve is reduced to zero, achieving zero incidence.

[0050] 3. In terms of energy consumption and materials, in the prior art, the loss rate of the embedded sleeve that occurs every day is high, which all exist in the installation process of the embedded sleeve. Because the sleeve bolt is not accurately jacked during the installation of the embedded sleeve, when tightening the embedded sleeve, the embedded sleeve is skewed, resulting in damage to the embedded sleeve and it cannot be reused. The setting of the guiding device not only ensures the accurate installation of the embedded sleeve but also reduces the manual inspection time. Only need the operator to start the function of installing the embedded sleeve with one key, realizing intelligent and automated production of the process, greatly improving the production efficiency, with simple operation, easy control, and controllable quality.
