[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0020] like Figures 1-4 As shown, an adjustable support device for arch construction includes a base frame 1, traveling wheels 2, uprights 3, and top frame 4 and 5;

[0021] There are four wheels 2, which are respectively set at the bottom of the four corners of the base frame 1;

[0022] The uprights 3 are provided in four parts, including a lower sleeve 31 and an upper telescopic rod 32. The lower sleeve 31 is fixedly installed on the upper part of the base frame 1, and the upper telescopic rod 32 is inserted into the lower sleeve 31. The lower sleeve 31 and the upper telescopic rod 32 are provided with multiple matching pin holes, which are then aligned and fixed by inserting pins.

[0023] Top frame 4 is installed on top of upright 3;

[0024] Arch 5 is set above the top frame 4 and supports the formwork for pouring concrete.

[0025] When using this device, first move it to the construction area using the wheels 2. Adjust the height of the uprights 3 according to the location of the concrete to be poured. After the upper telescopic rod 32 moves up and down within the lower sleeve 31, it is fixed by inserting a pin into the pin hole. At this time, the arch 5 supports the pouring template and conforms to the shape of the concrete to be poured. After the pouring operation is completed, remove the pin so that the upper telescopic rod 32 falls downward into the lower sleeve 31. The arch 5 then moves the pouring template downward to complete the demolding. Continue moving to the next work area.

[0026] like Figure 3 As shown, in a preferred embodiment, it also includes four jacks 6 respectively mounted on the upright 3; the base of the jack 6 is located on the side wall of the lower sleeve 31, and the telescopic rod of the jack 6 is connected to the side wall of the upper telescopic rod 32, driving the upper telescopic rod 32 to move. In this embodiment, the length of the upright 3 is adjusted using the jacks 6, and the telescopic rod of the jack 6 drives the upper telescopic rod 32 to move upward. After support is completed, it drives the upper telescopic rod 32 to move downward to return to its original position. Using the jacks 6 can provide better support and power, improving the stability of the device. Long-term lifting using hydraulic cylinders also poses technical risks, namely, the oil pump needs to work continuously for extended periods of oil supply, and stopping the oil supply can easily lead to oil return and detachment. Therefore, in this solution, when the upper load is large, the jacks 6 are used for lifting, and then the device is fixed with pins, separating the lifting structure from the fixing structure, making the device more stable.

[0027] like Figure 2 As shown, in a preferred embodiment, a synchronous oil pump 7 is also included. The synchronous oil pump 7 is connected to four jacks 6 via oil pipes, driving the four jacks 6 to move synchronously. In this embodiment, the synchronous oil pump 7 provides power to drive the four jacks 6 to move synchronously, supporting the top frame 4 at the same speed, which improves the stability of the device and makes it fit the upper arc more closely.

[0028] like Figure 4 As shown, in a preferred embodiment, the base frame 1 is provided with a pull ring 8. In this embodiment, after the pull ring 8 is provided on the base frame 1, a steel wire rope is passed through it, and the operator can adjust the position of the device by pulling the steel wire rope, which is more flexible.

[0029] The terms "connection" and "fixing" appearing in this utility model description can refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meaning of the above terms in this utility model should be understood according to the specific circumstances.
