Abstract
Description
Technical Field
[0001] This utility model belongs to the field of concrete constant temperature and humidity curing technology, specifically relating to a push-pull folding shed for constant temperature and humidity curing of track concrete. Background Technology
[0002] Currently, the curing of concrete poured for ballastless tracks involves manually sprinkling water as evenly as possible and then directly covering it with a film. This process is cumbersome, requires multiple people, increases labor costs, and cannot achieve constant temperature and humidity. The resulting poor curing conditions affect the quality of the concrete and create safety hazards. Utility Model Content
[0003] This utility model aims to provide a push-pull folding shed for constant temperature and humidity curing of track concrete. It has a good constant temperature and humidity curing effect and is easy to operate. It solves the problems of the current method of curing concrete poured for ballastless tracks, which involves manually sprinkling water as evenly as possible and then directly covering it with a film. This method is cumbersome, increases labor costs, and has poor curing effect.
[0004] Therefore, the technical solution adopted by this utility model is as follows: a push-pull folding shed for constant temperature and humidity curing of track concrete, including a foldable shed frame, a constant temperature and humidity curing mechanism installed on the foldable shed frame, and a tarpaulin erected on the foldable shed frame. The foldable shed frame includes several sets of driven traveling masts arranged in parallel front and rear, "X"-shaped connecting rods connecting adjacent driven traveling masts, and a traction active traveling mast driving the driven traveling masts. The constant temperature and humidity curing mechanism includes temperature and humidity sensors, cooling and humidifying pipelines, heating and humidifying pipelines, a water tank, and an electric heating steam generator. The temperature and humidity sensors are arranged at multiple points inside the folding shed frame, and the traction active traveling mast... The moving gantry includes a gantry body, roller mounting seats symmetrically located at the bottom of the gantry body, a drive wheel installed in the roller mounting seat, a drive motor that drives the drive wheel to move, auxiliary wheels installed at the front and rear ends of the roller mounting seat, and guide wheels installed at the bottom of the roller mounting seat and rolling along the side wall of the track base plate. The bottom of the driven gantry of the adjacent traction active gantry is fixed on the roller mounting seat. The bottom of the other driven gantry except the adjacent traction active gantry is provided with rollers. When the traction active gantry moves along the track base plate, it drives several driven gantry to move away from or closer to each other, thereby realizing the unfolding and folding of the foldable canopy.
[0005] As a preferred embodiment of the above scheme, the heating and humidifying pipeline consists of two symmetrically arranged pipes connected to the outlet of the electric heating steam generator. The heating and humidifying pipeline is equipped with heating nozzles fixed on the driven traveling gantry at intervals. The cooling and humidifying pipeline is installed longitudinally in the center on the top of the driven traveling gantry and is equipped with cooling nozzles at intervals. The water tank outlet pipe is connected to the cooling and humidifying pipeline and the electric heating steam generator respectively. Steam is sprayed evenly from the left and right sides of the heating and humidifying pipeline for rapid heating and humidification, and water is sprayed from the middle cooling and humidifying pipeline for rapid cooling and humidification.
[0006] A further preferred embodiment is that the water tank is equipped with a water level sensor, an electric heating rod, and a temperature sensor. The rear side wall of the water tank has symmetrical cleaning ports on the left and right sides, and the right side of the rear side wall of the water tank has a liquid level display window. The structure is reasonably designed and allows for flexible adjustment of the water tank temperature according to needs.
[0007] Further preferably, both the water tank and the electric steam generator are installed on the gantry body, making reasonable use of space and avoiding interference from intersecting wiring harnesses.
[0008] More preferably, the outlet end of the electric heating steam generator is equipped with a solenoid valve one, a pressure reducing valve, a filter, a high-pressure pump, and a solenoid valve two in sequence along the steam delivery direction. The equipment is reasonably arranged and the water spray volume is easy to adjust.
[0009] Further preferably, the tarpaulin is made of heat-insulating plastic material, which is a reasonable material selection.
[0010] The beneficial effects of this utility model are:
[0011] (1) Compared with the current method of manually sprinkling water as evenly as possible and then covering the concrete after pouring the ballastless track for curing, this solution uses a foldable scaffold that can be directly unfolded and combined with a tarpaulin to cover the concrete poured on the track base plate. This can be used to ensure the early and mid-term strength of the ballastless track concrete construction and provide a constant temperature and humidity curing environment. The foldable scaffold adopts a portal support frame structure, which can move on its own and facilitates the overall displacement of the curing device.
[0012] (2) A constant temperature and humidity curing mechanism is adopted to achieve temperature and humidity control of concrete curing. The temperature of the water tank is adjusted by the data transmitted by the temperature and humidity sensor, and the cooling and moisturizing pipeline or the heating and moisturizing pipeline is selected for water spraying. The temperature and humidity in the curing shed are monitored in real time, and it is determined whether heating or water is needed based on the measured temperature data, so as to ensure that the temperature and humidity inside the tarpaulin are always maintained within the predetermined curing standard range. The amount of water sprayed can be flexibly adjusted to achieve constant temperature and humidity curing of concrete, resulting in good curing effect and reduced manpower and material costs.
[0013] (3) The drive motor of the traction active traveling gantry provides the walking power. When the traction active traveling gantry moves along the track base plate, it can drive several driven traveling gantry to move away from or closer to each other, thereby realizing the unfolding and folding of the foldable canopy. After unfolding, the ballastless track is maintained. During the maintenance process, the distance between the support frames can be adjusted according to the needs of different working spaces, so that the entire device can adapt to working environments of various sizes. The driven traveling gantry are connected by "X"-shaped connecting rods. The distance between adjacent traveling gantry is adjusted by changing the included angle of the "X"-shaped connecting rods, and the structure is interlocked.
[0014] In summary, this utility model has the advantages of constant temperature and humidity curing of concrete, good curing effect, reduced manpower and material costs, and interlocking structure. Attached Figure Description
