[0002] Hollow slab beam is a common form of building structure, which is characterized by light weight, high strength, and easy construction. In the field of construction, hollow slab beams are often used to build floors, ceilings, roofs and other parts. In the construction of hollow slab beams, the formwork must be erected first, and then the steel bars must be installed according to the design requirements, and then the concrete is poured, and finally the maintenance work is carried out. During the hardening process of concrete, concrete is very sensitive to changes in temperature and humidity. If the maintenance work is improper and untimely, the water on the surface of the concrete will be lost too quickly, and cracks will appear. This directly affects the strength and durability of the concrete, and even endangers the safety of the engineering structure.

[0003] In the prior art, the maintenance of hollow slab beams is carried out naturally by covering with geotextiles and sprinkling water, which takes a long time, cannot effectively control the curing temperature, and has low economic benefits. Utility Model Content

[0036] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0037] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0038] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0039] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0040] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0041] The utility model embodiment provides a mobile maintenance device, referring to Figures 1 to 3 As shown, the embodiment of the utility model provides a mobile curing device, comprising: a mobile track 1 and a closed steam curing kiln 2 running on the mobile track 1;

[0042] The closed steaming kiln 2 comprises: a closed chamber 21, a running device 22, a steam pipe 23 and a control system;

[0043] The walking device 22 drives the closed chamber 21 to move on the moving track 1;

[0044] The steam pipe 23 is arranged on the inner wall of the closed cavity 21 and is used to spray steam of a specified temperature into the closed cavity 21;

[0045] The control system acquires the maintenance data in the closed chamber 21 and controls the injection temperature and intensity of the steam at the input end of the steam pipe 23 .

[0046] Further, the same movable track 1 is arranged along at least two plate beam construction stations;

[0047] The closed steaming kiln 2 moves along the moving track 1 between a plurality of slab beam construction stations.

[0048] It can be understood that the mobile curing device provided in this embodiment specifically refers to a curing device that moves between different slab beam construction stations. Therefore, it includes a mobile track 1 and a closed steaming kiln 2. The same mobile track 1 is set along at least two slab beam construction stations, that is, the closed steaming kiln 2 can be moved along the mobile track 1 between the first slab beam construction station, the second slab beam construction station, and even the nth slab beam construction station. Multiple slab beam construction stations share one closed steaming kiln 2, which is used in a continuous construction manner without interfering with each other, thereby improving the use efficiency of the closed steaming kiln 2. At the same time, compared with the hoisting curing kiln in the prior art, the closed steaming kiln 2 is moved by the mobile track 1, which shortens the hoisting time, avoids the cross-use of driving, greatly saves labor costs and time costs, and reduces the hoisting loss rate of the curing kiln, thereby reducing equipment costs.

[0049] Furthermore, the closed steaming kiln 2 includes: a closed chamber 21, a running device 22, a steam pipe 23 and a control system. The closed chamber 21 is the supporting body of the closed steaming kiln 2, and the running device 22 drives the closed chamber 21 to move on the moving track 1. The steam pipe 23 is arranged on the inner wall of the closed chamber 21 to transport hot steam into the closed chamber 21. The closed steaming kiln 2 also includes a control system for controlling the temperature and strength of the steam transported by the steam pipe 23.

[0050] The embodiment provided by the utility model enables multiple slab beam construction stations to share one maintenance device by moving the closed cavity on a moving track, thereby improving the efficiency and convenience of the device and reducing the cost of use. At the same time, the steam pipeline is intelligently controlled by the control system to provide a constant and uniform steam temperature and humidity, making full use of the thermal energy of the steam. The temperature and humidity are stabilized within the range set by the specification, thereby improving the early strength of the concrete. The embodiment provided by the utility model can not only save time and labor costs, but also ensure that the prefabricated components meet the highest quality standards and improve the accuracy of the device in maintaining the slab beams.

[0051] In another optional embodiment provided by the present utility model, refer to Figure 2 , Figure 4 and Figure 5 As shown, the closed chamber 21 includes a plurality of box sections connected along the direction of the moving track 1;

[0052] Each box segment includes a running device 22, and the running devices 22 arranged on multiple box segments move synchronously.

[0053] The closed cavity 21 includes side plates 211 arranged along the extending direction of the moving track 1 and a top plate 212 arranged between the side plates 211;

[0054] The length of the side plate 211 is not less than the length of the plate beam construction station;

[0055] The height of the side plate 211 is greater than the height of the plate beam construction station.

[0056] It is understandable that the closed cavity 21 may include a plurality of interconnected box sections, and any box section includes relatively arranged side panels 211 and a top panel 212 connected between the side panels 211. The side panels 211 are arranged vertically, and the top panel 212 is connected to the top of the side panels 211. The volume of the closed cavity 21 needs to be adapted to the size of the slab beam construction station. Generally speaking, the length of the side panel 211 is not less than the length of the slab beam construction station. Specifically, the length of the side panel 211 is 3m longer than the slab beam construction station. The height of the side panel 211 is greater than the height of the slab beam construction station. Ensure that the closed cavity 21 can completely "wrap" the slab beam construction station.

[0057] When the closed steaming kiln 2 is moved, a plurality of box sections move synchronously.

[0058] In another optional embodiment provided by the present invention, rolling shutter doors 24 are further provided at both ends of the closed cavity 21 along the direction of the moving track 1 .

[0059] It is understandable that when the closed chamber 21 is undergoing maintenance work, the rolling shutters 24 disposed at both ends of the closed chamber 21 are closed, and the closed chamber 21 becomes a cavity closed on four sides, thereby ensuring that the temperature in the closed chamber 21 is constant.

[0060] In another optional embodiment provided by the present utility model, the walking device 22 includes a walking wheel 221 and a driving motor 222;

[0061] The running wheel 221 is arranged at the bottom of the closed cavity 21 and is adapted to the moving track 1;

[0062] The driving motor 222 is disposed on the outer wall of the closed cavity 21 and is electrically connected to the walking wheel 221 .

[0063] It can be understood that the walking device 22 is used to drive the closed cavity 21 to walk on the moving track 1. Specifically, the walking device 22 includes a walking wheel 221 and a driving motor 222. The driving wheel 221 is arranged at the bottom of the closed cavity 21. When the closed cavity 21 includes multiple box sections, multiple driving wheels 221 can be arranged according to the box sections. The walking device 22 also includes a driving motor 222, which is electrically connected to the walking wheel 221, and the driving motor 222 provides power for the walking wheel 221. The driving motor 222 is arranged outside the closed cavity 21, specifically, it can be arranged at the top of the closed cavity 21. Similarly, the walking device 22 can include multiple driving motors 222, and the same driving motor 222 can be electrically connected to the walking wheel 221 connected to the same box section. It should be noted that multiple driving motors 222 need to be linked to ensure that multiple box sections of the closed cavity 21 move synchronously.

[0064] In another optional embodiment provided by the present invention, the steam pipe 23 is arranged along the inner wall of the side plate 211 and is located at one end of the side plate 211 close to the moving track 1 .

[0065] It is understandable that the steam pipe 23 can be a 50 steel pipe, and a hole is opened on the top of the steel pipe as a steam injection hole. The steam pipe 23 is arranged on the inner wall of the side plate 211, surrounding the entire rectangular workstation. And the steam pipe 23 is arranged near the bottom of the side plate 211, so that the steam output from the steam pipe 23 can move upward and fill the entire closed cavity 21.

[0066] In another optional embodiment provided by the present utility model, the control system includes a temperature sensor and a humidity sensor disposed in the closed cavity 21, and a control center disposed outside the closed cavity 21;

[0067] The temperature sensor and the humidity sensor are both electrically connected to the control center.

[0068] It is understandable that the control system includes front-end sensing devices such as temperature sensors, humidity sensors and a control center at the back end. The temperature sensor and humidity sensor obtain the temperature and humidity data in the closed cavity 21 in real time and transmit it to the control center. The control center sets four processes: static, heating, constant temperature and cooling. Each process sets the temperature and time that meet the requirements of the specification. Steam curing can effectively control the curing temperature change, and the influence of the ambient temperature on the curing can be reduced by the heating, constant temperature and cooling process. Compared with the natural curing of covering with geotextile and sprinkling water in the prior art, it can save 4 days.

[0069] In another optional embodiment provided by the utility model, a cable trough is further provided on the outer side of any movable track 1. Both the movable track 1 and the cable trough are U-shaped troughs.

[0070] It is understandable that the moving track 1 and the cable trough can be U-shaped troughs. The width of the moving track 1 is 25 cm, and 50 tracks are installed inside. A U-shaped trough is welded on the outside of the moving track 1 on either side as a cable running track for the wiring channel of the drive motor 222, the rolling door 24, the sensor, etc.

[0071] In summary, the mobile maintenance device provided by the utility model achieves at least the following beneficial effects:

[0072] The embodiment provided by the utility model enables multiple slab beam construction stations to share one maintenance device by moving the closed cavity on a moving track, thereby improving the efficiency and convenience of the device and reducing the cost of use. At the same time, the steam pipeline is intelligently controlled by the control system to provide a constant and uniform steam temperature and humidity, making full use of the thermal energy of the steam. The temperature and humidity are stabilized within the range set by the specification, thereby improving the early strength of the concrete. The embodiment provided by the utility model can not only save time and labor costs, but also ensure that the prefabricated components meet the highest quality standards and improve the accuracy of the device in maintaining the slab beams.
