Description

Technical Field

[0001] This utility model relates to the field of prefabrication of double-block railway sleepers, and in particular to a steam curing system and production line for double-block railway sleepers. Background Technology

[0002] With the rapid development of high-speed railways, the use of double-block sleepers is increasing. However, sleeper prefabrication plants are often affected by land acquisition requirements. Therefore, to achieve a more compact layout and higher space utilization, the production line is usually set up in a loop. For example, loading and unloading stations are set up on opposite sides of the steam curing area. The sequence is: unloading station → demolding station → demolding station → sleeve installation station → rebar and grout clamp installation station → temperature adjustment station → concrete placement and vibration station → grout clamp removal station → loading station, forming a loop with the steam curing area. The demolding station also connects to the stacking station. With this arrangement, if the gantry crane lifts the steam-cured sleepers from the steam curing tank, moves them laterally to the unloading station, and then descends until the steam curing tank is empty, and then lifts the sleepers to be steam-cured from the loading station to the top of the steam curing tank and puts them into the steam curing tank, it will result in a large number of sleepers that have finished steam curing in batches. This will require a large number of subsequent demolding devices and high demolding efficiency. Otherwise, a temporary storage area will be needed, increasing the factory building's footprint. If the gantry cranes are used for loading and unloading in an alternating manner, the gantry cranes need to move back and forth around the steam curing area, resulting in a long travel distance and poor loading and unloading efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing steam curing devices in balancing factory space limitations and steam curing loading and unloading efficiency, and to provide a steam curing system and production line for double-block sleepers.

[0004] In a first aspect, this utility model provides a steam curing system for a double-block sleeper, including a steam curing zone, a loading station and a unloading station arranged side by side, wherein the loading station and the unloading station are both located on the same side of the steam curing zone, and the steam curing zone includes at least two steam curing tanks arranged side by side. This invention provides a steam curing system for double-block railway sleepers, which has multiple steam curing tanks. The loading and unloading stations for the steam curing process are located on the same side of the steam curing area. This allows the hoisting device to lift the completed sleeper mold from one of the steam curing tanks and move it laterally to the unloading station. Then, it can lift the sleeper mold to be cured from the adjacent loading station to another steam curing tank (the loading and unloading order is not limited). This effectively connects the loading and unloading of the steam curing process, shortens the travel distance of the hoisting device in completing one loading and unloading cycle, effectively improves the efficiency of loading and unloading, and optimizes the layout of the factory space.

[0005] Preferably, it also includes a transfer device for transferring the sleeper mold from the unloading grout clamping station to a transition station. The unloading grout clamping station is located on one side of the end face of the steam curing zone, and the transition station is arranged colinearly with the loading station.

[0006] The production line position corresponding to the unloading slurry clamp station was adjusted, and the layout structure of the production line along the width of the steam curing zone was further optimized.

[0007] Preferably, the transfer device includes a trolley and a guide rail. The trolley can move along the guide rail and can be raised and lowered. The guide rail connects the unloading slurry clamping station and the transition station. The unloading slurry clamping station is directly opposite the steam curing tank in the steam curing area that is farthest from the feeding station. A temporary storage rack is also provided between the unloading slurry clamping station and the transition station.

[0008] The trolley moves along the guide rail to the unloading grout clamp station. By raising the trolley, the sleeper mold at that station can be supported and moved. Alternatively, the sleeper mold can be placed on a temporary storage rack or transition station and then lowered and moved to another position.

[0009] It can effectively connect the unloading grout clamp station and the transition station, and make full use of the space in the transfer position for temporary storage of sleeper molds, further optimizing the space layout.

[0010] Preferably, the temporary storage rack includes two spaced-apart support frames arranged longitudinally along the guide rail.

[0011] The spacing between the two support frames is set according to the actual situation.

[0012] Preferably, the feeding station is located between the unloading station and the steam curing zone.

[0013] Preferably, it also includes a gantry crane.

[0014] Preferably, both the loading station and the unloading station include roller conveyors. The width of the roller conveyors is adapted to the width of the sleeper mold. The sleeper mold includes two rows of double-block mold units arranged side by side, with 3-5 double-block mold units in each row.

[0015] Preferably, the width of the steam curing tank is adapted to the total width of two sleeper molds, and the depth of the steam curing tank is adapted to the total height of 8-10 sleeper molds.

[0016] While completing the preparation of as many sleepers as possible in a single batch, it is also conducive to spatial layout.

[0017] Preferably, the top surface of the sleeper mold has a pad.

[0018] This facilitates the entry of steam into the stacked sleeper molds.

[0019] Secondly, this utility model provides a production line for a double-block sleeper, including a steam curing system for a double-block sleeper as described above, and further including a demolding station, a mold cleaning station, a sleeve installation station, a rebar and grout clamp installation station, a temperature adjustment station, a material placement and vibration station, a grout clamp unloading station, and a PLC control system. The demolding station, mold cleaning station, sleeve installation station, and rebar and grout clamp installation station are arranged in the same line as the material unloading station. The temperature adjustment station, material placement and vibration station, and grout clamp unloading station are arranged in the same line. The rebar and grout clamp installation station and the temperature adjustment station are connected by a transverse movement device.

[0020] This utility model provides a production line for a double-block sleeper, which has a better factory layout, which helps to improve the utilization rate of the factory and increase the efficiency of sleeper production.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a steam curing system for double-block railway sleepers, which has multiple steam curing tanks. The loading and unloading stations of the steam curing process are located on the same side of the steam curing area, so that the hoisting device can lift the railway sleeper mold that has finished curing from one of the steam curing tanks and move it laterally to the unloading station. Then, it can lift the railway sleeper mold to be cured from the adjacent loading station to the other steam curing tank by moving it laterally. This can effectively connect the loading and unloading of the steam curing process, shorten the movement distance of the hoisting device in completing one loading and unloading process, effectively improve the efficiency of loading and unloading, and optimize the layout of the factory space.

[0022] 2. This utility model provides a production line for a double-block sleeper, which has a better factory layout, which is conducive to improving the utilization rate of the factory and increasing the efficiency of sleeper production. Attached Figure Description

[0031] Example 1 like Figures 1-2 As shown, a steam curing system for a double-block sleeper includes a steam curing zone 1, a loading station 2, and a unloading station 3 arranged side by side, as well as a gantry crane (not shown) and a transfer device. The loading station 2 and the unloading station 3 are both located on the same side of the steam curing zone 1. The steam curing zone 1 includes at least two steam curing tanks 11 arranged side by side. The transfer device is used to transfer the sleeper mold 0 from the unloading grout clamp station 4 to the transition station 5.

[0032] Specifically, this embodiment example has two steam curing zones 1, arranged longitudinally along the loading station 2. The loading station 2 is located between the unloading station 3 and the steam curing zone 1. Each steam curing zone 1 has three steam curing pools 11. The width of the steam curing pool 11 is adapted to the total width of two sleeper molds 0, and the depth of the steam curing pool 11 is adapted to the total height of 8-10 sleeper molds 0. The sleeper mold 0 includes a rectangular frame with a central partition. Five double-block mold units 01 are located on each side of the partition, though other numbers can be used depending on the site conditions. The double-block mold units 01 on the same side are distributed longitudinally along the frame. Each double-block mold unit 01 includes two mold shells for preparing double-block sleepers. Several pads 02 are located on the top surface of the frame. The top surface of the partition is lower than the top surface of the frame. When the sleeper molds 0 are stacked, the lower top surface of the partition and the pads 02 allow for a larger gap between adjacent molds, increasing the flow area and ensuring the curing effect of the stacked molds. Each steam curing zone 1 has a corresponding loading station 2 and unloading station 3. The loading stations 2 and unloading stations 3 of the two steam curing zones 1 are coaxially arranged, ensuring a greater distance from the transition station 5. Figure 1 The loading station 2 and unloading station 3 (on the left side of the middle section) can be... Figure 1 The material loading station 2 and unloading station 3 on the right side of the middle section are used for material transfer.

[0033] The unloading slurry clamping station 4 is set on one side of the end face of the steam curing zone 1, and the transition station 5 is arranged colinearly with the feeding station 2, as shown below. Figure 1 As shown, the loading station 2, unloading station 3, unloading slurry clamp station 4 and transition station 5 all include roller conveyors, which move the sleeper mold 0 longitudinally along the corresponding station by rotating the rollers.

[0034] The transfer device includes a trolley 61 and a guide rail 62. The trolley 61 can move along the guide rail 62 and can be raised and lowered. The guide rail 62 connects the unloading slurry clamping station 4 and the transition station 5. The unloading slurry clamping station 4 is directly opposite the steam curing tank 11 in the steam curing zone 1 that is farthest from the feeding station 2. A temporary storage rack is also provided between the unloading slurry clamping station 4 and the transition station 5. The temporary storage rack includes two spaced support frames 63. The support frames 63 are arranged longitudinally along the guide rail 62 and can be evenly located on the outside of the two trolleys.

[0035] In one or more embodiments, the transfer device may also be other forms in the prior art, such as a robotic arm or a translation device.

[0036] In one or more embodiments, the support frame 63 may adopt other support structure forms.

[0037] This utility model provides a steam curing system for a double-block sleeper, which has multiple steam curing tanks 11. The loading station 2 and unloading station 3 of the steam curing process are located on the same side of the steam curing area 1, so that the hoisting device can lift the sleeper mold that has finished curing from one of the steam curing tanks 11 and move it laterally to the unloading station 3. Then, the sleeper mold to be cured can be lifted from the adjacent loading station 2 and moved to the other steam curing tank 11 by lateral movement (the order of loading and unloading is not limited). This can effectively connect the loading and unloading of the steam curing process, shorten the movement distance of the hoisting device in completing one loading and unloading process, effectively improve the efficiency of loading and unloading, and optimize the layout of the factory space.

[0038] Example 2 like Figures 1-3 As shown, a production line for a double-block sleeper includes a steam curing system for a double-block sleeper as described in Example 1, and further includes a demolding station 71, a demolding station 72, a sleeve installation station 73, a rebar and grout clamp installation station 74, a temperature adjustment station 75, a material placement and vibration station 76, a grout clamp removal station 4, and a PLC control system. The demolding station 71, the demolding station 72, the sleeve installation station 73, and the rebar and grout clamp installation station 74 are arranged co-linearly with the material unloading station 3. The temperature adjustment station 75, the material placement and vibration station 76, and the grout clamp removal station 4 are also arranged co-linearly. The rebar and grout clamp installation station 74 and the temperature adjustment station 75 are connected by a transverse movement device.

[0039] Demolding station 71 includes a first station collinear with blanking station 3 and a second station on the side of the first station. Figure 3The lower middle station), there is a turning machine between the first station and the second station. After the sleeper mold 0 is transferred to the first station, it is turned over by the turning machine and placed on the second station (the top surface of the sleeper mold 0 is placed downwards). It is demolded by vibration and other means in the second station. After demolding, it is sent to the storage area by the conveyor structure.

[0040] Demolding station 71 is followed by demolding station 72, and demolding station 72 is followed by sleeve installation station 73, where release agent is sprayed and sleeves are installed. Sleeve installation station 73 is followed by rebar and grout clamp installation station 74, where truss rebar and grout clamps are installed. Rebar and grout clamp installation station 74 is connected to temperature regulation station 75 (the canopy covering this station is not shown) via a transverse movement device. The transverse movement device can be designed similarly to a transfer device. Temperature regulation station 75 is used to regulate the temperature of the mold to be poured. Temperature regulation station 75 is followed by concrete placement and vibration station 76 (concrete placement funnel not shown). After concrete placement and vibration, it is transferred to grout clamp removal station 4. The sleeper mold 0 at position 4 is moved to transition station 5 via a transfer device. Transition station 5 can be set up independently or formed by extending the loading station 2. Then, the sleeper mold 0 at loading station 2 is transferred to the corresponding curing tank 11 by a gantry crane. Before the gantry crane moves laterally to loading station 2 to obtain the next sleeper mold 0, the sleeper mold 0 that has finished curing in another curing tank 11 can be lifted and moved to unloading station 3 to continue the loading process. The sleeper mold 0 at unloading station 3 is separated from the sleeper at demolding station 71. The sleeper enters the second station to be transferred to the finished product area, and the sleeper mold 0 enters the mold cleaning station 72 again. All of the above stations include roller conveyors.

[0041] In one or more embodiments, the traverse device can be set between two other adjacent workstations to allow the line to rotate, depending on actual needs.

[0042] This utility model provides a production line for a double-block sleeper, which has a better factory layout, which helps to improve the utilization rate of the factory and increase the efficiency of sleeper production.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
