[0002] Steam insulated pipes play a vital role in industrial production and life. It is a pipe used to transport high-temperature steam, mainly composed of an inner pipe, an insulation layer and an outer shell. The insulation materials of the outer shell of the pipe, such as aluminum silicate and glass wool, can reduce heat loss, improve the efficiency of steam transportation, reduce energy consumption, and also improve the efficiency of industrial production. Steam insulated pipes can also reduce environmental pollution to a certain extent. As a clean energy source, steam can replace raw energy sources such as coal and gas, reducing environmental pollution and energy waste.

[0003] The existing device will have the following problems when in use: when double pipes are directly buried, a gap is usually reserved for the double pipes. However, after long-term use, the pipes will move, causing friction between the pipes, thereby damaging the pipes. Secondly, it is difficult to understand the condition of the pipes in a timely manner, which increases the incidence of dangerous use of the pipes. Summary of the invention

[0004] The object of the present invention is to provide a prefabricated direct-buried steam insulation pipe and a balanced support thereof to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a prefabricated direct-buried steam insulation pipe, comprising a protective base, a protective pad, and a pipe body, wherein a protective pad is arranged inside the protective base, and the pipe body is arranged on the protective pad. When the pipe body is compressed, the protective pad is used for buffering to reduce the pressure on the protective base. A top plate is arranged at the bottom of the pipe body, and a connecting rod is connected to the bottom of the top plate. One end of the connecting rod extends to the inside of the slot and is fixedly connected with a spring. When the pressure on the pipe body drives the connecting rod at the bottom of the top plate to move, the connecting rod squeezes the spring to start the induction switch, and the induction switch starts the signal transmitter to transmit the signal to the maintenance department in time to remind the abnormal situation of the pipe body. A limit plate is arranged on the top of the pipe body, and the limit plate is connected to the protective base by installing bolts. The protective base and the limit plate are installed by the installing bolts, and the pipe body is fixed by the protective base to avoid the two groups of pipe bodies being directly buried together and rubbing against each other, which may cause damage to the pipe body.

[0006] In a further embodiment, a slot is provided inside the protective base, a spring is fixedly connected inside the slot, a signal transmitter is installed inside the slot, an induction switch is connected to the top of the signal transmitter, the induction switch activates the signal transmitter, and the signal transmitter transmits the signal to the terminal, thereby facilitating timely discovery by staff.

[0007] In a further embodiment, an insertion rod is provided at the bottom of the limit plate, and a slot is opened at the top of the protective base. The insertion rod fits into the slot, and the insertion rod on the limit plate is aligned with the slot and inserted into the slot, so as to pre-position the limit plate and avoid displacement of the limit plate, which would make the installation of the mounting bolts inconvenient.

[0008] In a further embodiment, an anti-skid pad is provided on the inner bottom side of the limit plate. The anti-skid pad is made of rubber material. The anti-skid pad reduces the wear on the pipeline body caused by the installation of the limit plate, thereby improving the stability of the pipeline body.

Then, the electric telescopic rod A is started to drive the insulation pipe to move up to the appropriate position, and the upper semicircular bracket is driven to move down and the lower semicircular bracket is driven to move up until the upper semicircular bracket is abutted against the lower semicircular bracket, and then polyurethane is poured. Through the upper and lower semicircular brackets, the insulation pipe is moved to the appropriate position. The cooling channel set in the arc wall of the circular bracket transports water from the coolant delivery equipment to the cooling channel through a water pipe to cool down the heat released during the solidification of the polyurethane. After the processing of the polyurethane insulation layer is completed, the electric telescopic rod B is started to retract to separate the upper semicircular bracket and the lower semicircular bracket. The retraction of the electric telescopic rod A drives the insulation pipe down to the horizontal plane of the base. The staff then unloads the insulation pipe through the ramp plate at the other end and the roller.

[0016] By adopting the above technical solution, when the upper semicircular bracket and the lower semicircular bracket move relative to each other, the retaining rings installed at the channel openings at both ends of the semicircular bracket abut against the outer wall of the insulation pipe, and cooperate with the sealing gasket set on the inner wall of the retaining ring to increase the sealing between the semicircular bracket and the insulation pipe, thereby avoiding polyurethane leakage.

[0017] Preferably, two groups of the clamping plates are provided, one side surface of the clamping plate is provided as a semi-arc groove type, and an anti-slip pad is installed on the wall of the semi-arc groove of the clamping plate.

[0022] By adopting the above technical solution, the circuit controller installed on the motor changes the rotation direction of the motor shaft by swapping the positive and negative poles of the DC motor power supply, thereby achieving the purpose of bidirectional alternating rotation of the motor shaft. The protrusion installed on the ball nut is slidably connected with the slide groove opened on the inner wall of the bracket, which limits the rotation of the ball nut and ensures the stability of the ball nut when moving.

[0023] Compared with the prior art, the present invention has the following beneficial effects: The pipe body is fixed by a protective base to prevent the two groups of pipe bodies from being buried directly together and rubbing against each other, which may cause damage to the pipe body. A gap is provided between the two groups of pipe bodies, the supporting points of the pipe body are increased, and the supporting strength of the pipe body is improved.
