Description

Technical Field

[0001] This utility model relates to the field of concrete sleeper maintenance technology, and more specifically, to a secondary maintenance device for concrete sleepers. Background Technology

[0002] Concrete sleepers are concrete products made by mixing cement, sand, stone, water and admixtures in a certain proportion, pouring the mixture into a modular mold containing steel wire or steel bars and sleeper accessories, and then using methods such as vibration molding or load vibration molding and steam curing.

[0003] Production standards require that concrete sleepers continue to be moisturized and cured for more than 3 days after demolding in summer. The traditional method is to cover them with geotextile and use water trucks for curing. However, at this time, the concrete sleepers in the curing area are easily exposed to strong sunlight, which leads to the problem of excessive moisture evaporation. After being exposed to strong sunlight, on the one hand, the frequency of water curing increases, and on the other hand, prolonged exposure of the concrete sleepers to the sun can easily cause surface cracks, thus affecting product quality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a secondary curing device for concrete sleepers.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A secondary curing device for concrete railway sleepers includes a secondary curing workshop with windows, a concrete sleeper placement rack, an electric sunshade, a light sensor, a temperature and humidity sensor, a temperature and humidity regulator, a drive assembly, a humidification box, a misting nozzle, and a water supply assembly.

[0007] Several concrete sleeper racks are symmetrically placed inside the secondary curing workshop to allow the concrete sleepers to be stored at intervals.

[0008] The electric sunshade is installed on the inner wall of the secondary curing workshop and above the windows;

[0009] The light sensor is located at the end of the electric sunshade and is electrically connected to the electric sunshade.

[0010] Temperature and humidity sensors and temperature and humidity regulators are all installed inside the secondary curing workshop and are electrically connected.

[0011] The drive assembly is installed on the inner top wall of the secondary curing workshop and is connected to a humidification box with an internal hollow structure that is adapted to the height of the concrete sleeper placement frame. The humidification box is located between the two concrete sleeper placement frames.

[0012] The atomizing nozzles are symmetrically arranged at equal intervals along the height of the humidification box and are connected to the interior of the humidification box.

[0013] The water supply components are located inside the secondary curing workshop and are connected to the humidification box via hoses.

[0014] Furthermore, the concrete sleeper placement frame includes a U-shaped frame, rollers, and perforated partitions. The bottom of the U-shaped frame is provided with rollers, and several perforated partitions are equidistantly arranged on the U-shaped frame.

[0015] The above solution enables the batch and interval storage of concrete sleepers through concrete sleeper placement racks, facilitating their transfer.

[0016] Furthermore, the U-shaped frame is provided with a limiting rod located behind and in contact with the porous partition.

[0017] The above solution can prevent concrete sleepers from falling off the back of the perforated partition during placement by using a limiting rod, which can limit their movement in both the front and rear directions.

[0018] Furthermore, symmetrical limit plates are set in the secondary curing workshop to define the placement areas of the concrete sleeper placement racks on both sides.

[0019] The above scheme can limit the placement area of ​​the concrete sleeper placement frame by using a limiting plate during the process of pushing the frame into the secondary curing workshop.

[0020] Furthermore, the drive assembly includes a lead screw assembly and a connecting rod. The inner top wall of the secondary maintenance workshop is provided with a lead screw assembly whose length is adapted to it. The lead screw assembly is connected to a humidification box through the connecting rod.

[0021] Furthermore, the water supply assembly includes a water tank and a high-pressure water pump. The water tank and the high-pressure water pump connected to the bottom of the water tank are installed on the floor inside the secondary maintenance workshop. The high-pressure water pump is connected to the humidification box through a hose.

[0022] The above solution, through the cooperation of the drive component and the water supply component, enables water mist to be sprayed sequentially onto each concrete sleeper placement rack, thereby humidifying the concrete sleepers at different heights on the rack.

[0023] Furthermore, an ultrasonic level sensor is installed inside the water tank, and the ultrasonic level sensor is electrically connected to a buzzer installed outside the water tank.

[0024] In the above scheme, when the water level in the tank is lower than the lower limit set in the ultrasonic level sensor, the ultrasonic level sensor sends a feedback signal to the controller, and the controller then controls the buzzer to sound, thereby reminding the staff to add water.

[0025] Furthermore, the secondary maintenance workshop is equipped with a display screen.

[0026] The above solution allows for a more intuitive display of the temperature and humidity values ​​in the secondary curing workshop via a screen.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] Compared to existing technologies, this device, through the use of electric sunshades and light sensors during the secondary curing process of concrete sleepers, can prevent them from being exposed to strong sunlight, thereby solving the problem of excessive moisture evaporation from the concrete sleepers. This reduces the frequency of water spraying and avoids cracking of the concrete sleeper surface caused by prolonged exposure to sunlight. In addition, by spraying water mist to humidify several concrete sleepers sequentially, the moisture retention effect of the concrete sleepers is excellent, and the quality of the product after secondary curing is improved.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0034] like Figure 1 and Figure 2 As shown, a secondary curing device for concrete sleepers includes a secondary curing workshop 1. The secondary curing workshop 1 includes a window 11, a concrete sleeper placement rack, an electric sunshade 17, a light sensor 18, a temperature and humidity sensor, a temperature and humidity regulator, a drive assembly, a humidification box 23, an atomizing nozzle 24, and a water supply assembly.

[0035] Several concrete sleeper placement racks are symmetrically placed inside the secondary curing workshop 1 to allow the concrete sleepers to be stored at intervals.

[0036] The electric sunshade 17 is installed on the inner wall of the secondary curing workshop 1 and above the window 11;

[0037] The light sensor 18 is located at the end of the curtain body of the motorized sunshade 17 and is electrically connected to the motorized sunshade 17.

[0038] Temperature and humidity sensors and temperature and humidity regulators are all installed inside the secondary curing workshop 1 and are electrically connected (the temperature and humidity regulators are specifically industrial air conditioners. The industrial air conditioners work in conjunction with the intelligent sensors through a variable frequency compressor. They can simultaneously regulate temperature and humidity, control the temperature error within ±1℃ and the humidity error within ±5%. The industrial air conditioners are not shown in the figure and belong to the prior art. Their working principle will not be described).

[0039] The drive assembly is installed on the inner top wall of the secondary curing workshop 1 and is connected to a humidification box 23 that is hollow inside and adapted to the height of the concrete sleeper placement frame. The humidification box 23 is located between the two concrete sleeper placement frames.

[0040] The atomizing nozzles 24 are symmetrically arranged at equal intervals along the height direction of the humidification box 23 and are connected to the interior of the humidification box 23.

[0041] The water supply unit is located inside the secondary curing workshop 1 and is connected to the humidification box 23 via a hose.

[0042] Further refinements of the embodiments of this utility model, such as... Figure 2 As shown, the concrete sleeper placement frame includes a U-shaped frame 12, rollers 13 and perforated partitions 14. The bottom of the U-shaped frame 12 is provided with rollers 13 and a number of perforated partitions 14 are provided at equal intervals on the U-shaped frame 12.

[0043] In a further optimization of the above embodiment, a limiting rod 15 is provided on the U-shaped frame 12, which is located behind and in contact with the porous partition 14; the limiting rod 15 can prevent the concrete sleeper from falling off the rear side of the porous partition 14 during placement, and can limit it in the front and rear directions.

[0044] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, limit plates 16 are symmetrically installed in the secondary curing workshop 1 to define the placement areas of the concrete sleeper placement frames on both sides.

[0045] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, the drive assembly includes a lead screw assembly 21 and a connecting rod 22. The lead screw assembly 21 with a length adapted to the inner top wall of the secondary maintenance workshop 1 is provided. The lead screw assembly 21 is connected to the humidification box 23 through the connecting rod 22.

[0046] Further refinements of the embodiments of this utility model, such as... Figure 1As shown, the water supply components include a water tank 25 and a high-pressure water pump 26. The water tank 25 and the high-pressure water pump 26 connected to the bottom of the water tank 25 are installed on the ground inside the secondary maintenance workshop 1. The high-pressure water pump 26 is connected to the humidification box 23 through a hose.

[0047] In a further optimization of the above embodiment, an ultrasonic level sensor is installed inside the water tank 25, and the ultrasonic level sensor is electrically connected to a buzzer installed outside the water tank 25; the ultrasonic level sensor and the buzzer are not shown in the figure.

[0048] It should be noted that the electric sunshade 17, light sensor 18, temperature and humidity sensor, temperature and humidity regulator, lead screw assembly 21, and high-pressure water pump 26 are all electrically connected to the controller, which is not shown in the figure.

[0049] The working process of this utility model:

[0050] First, concrete sleepers are placed at intervals on concrete sleeper placement racks. Then, multiple concrete sleeper placement racks are manually pushed into the secondary curing workshop 1 in sequence and placed in rows one after another. During the process of pushing the concrete sleeper placement racks in, the placement area can be limited by the limiting plate 16. At the same time, the concrete sleeper placement racks are positioned so that they face the atomizing nozzle 24 after placement. Then, the locking buckle stops the roller 13. The locking buckle is shown in the figure but is not labeled.

[0051] After all the concrete sleeper placement racks are in place, the controller controls the screw assembly 21 to work, which in turn drives the humidification box 23 to move back and forth at a uniform speed. At the same time, the controller controls the high-pressure water pump 26 to work, drawing water from the water tank 25 and injecting it into the humidification box 23, which is then atomized and pressurized and sprayed out. The water mist is then sprayed onto each concrete sleeper placement rack in sequence, thus carrying out the humidification process for the concrete sleepers at different heights on the placement rack (the porous partition 14 allows the water mist to move downwards in sequence). After the humidification box 23 has completed 2-3 rounds of back-and-forth motion, one round of humidification and curing process for the concrete sleepers is completed.

[0052] If the sunlight is strong, the light sensor 18 sends a signal to the controller, which then controls the electric sunshade 17 to descend to prevent the concrete sleepers from being exposed to the sun. When the sunlight is weak or it is nighttime, the controller controls the electric sunshade 17 to retract.

[0053] During the curing process, the temperature and humidity values ​​of the secondary curing workshop 1 are detected and fed back in real time by temperature and humidity sensors. The operation of temperature and humidity regulators is controlled according to the real-time temperature and humidity values ​​to adjust the environmental parameters of the secondary curing workshop 1, thereby ensuring that the secondary curing environment of the concrete sleepers is suitable.

[0054] As the humidification process proceeds, when the water level in water tank 25 falls below the lower limit set in the ultrasonic level sensor, the ultrasonic level sensor sends a feedback signal to the controller, which then controls the buzzer to sound, thus reminding staff to add water.

[0055] Compared to existing technologies, this device, through the use of electric sunshades and light sensors during the secondary curing process of concrete sleepers, can prevent them from being exposed to strong sunlight, thereby solving the problem of excessive moisture evaporation from the concrete sleepers. This reduces the frequency of water spraying and avoids cracking of the concrete sleeper surface caused by prolonged exposure to sunlight. In addition, by spraying water mist to humidify several concrete sleepers sequentially, the moisture retention effect of the concrete sleepers is excellent, and the quality of the product after secondary curing is improved.

[0056] In some embodiments, a display screen is provided inside the secondary curing workshop 1, which is not shown in the figure; in this embodiment, the temperature and humidity values ​​of the secondary curing workshop 1 can be displayed more intuitively through the display screen.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
