[0001] The utility model belongs to the technical field of cold spray inflation equipment, and particularly relates to a portable inflation device. Background Art

[0002] The primary function of the cold-jet inflation system is to eject air radially from the rocket body, actively causing the three-stage separation to flip, preventing the three-stage separation from continuing to accelerate in a directional manner and colliding with the final stage due to residual propellant. Currently, the cold-jet inflation system primarily uses a throttle valve, shut-off valve, pressure gauge, and service valve to inflate a high-pressure gas cylinder. This simple inflation method consists of a cold-jet cylinder, cold-air nozzle, and inflation valve.

[0003] The current inflatable equipment has the following problems during use:

[0004] 1. The existing inflation equipment is relatively simple in composition, with poor reliability, many pipe interfaces, inconvenient operation, and the risk of pipeline leakage. At the same time, the arrow body is transferred simultaneously on the arrow during the inflation process of the equipment, the operating environment is not safe enough, and the high-pressure gas cylinder is fixed on the support vehicle, which makes the on-site order seem irregular.

[0005] 2. During the inflation process, the high-pressure gas pipe and gas cylinder need to be fixed on the support vehicle, which is not conducive to movement; and the height and horizontal position of the inflation equipment are not easy to adjust; it is impossible to quickly align the inflation equipment for inflation; it is inconvenient for the staff to perform inflation operations, which reduces the inflation efficiency. Summary of the Invention

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a portable inflation device, comprising a base, which is liftable and adjustable by a lifting mechanism and is connected to an inflation platform, on which a cold spray inflation device is installed, the cold spray inflation device comprising an air intake pipe, on which an air intake pressure gauge and an air intake shut-off valve are provided, the air intake pipe is connected to an inflation pipe and an exhaust pipe respectively through a three-way valve and a high-pressure pipeline, the inflation pipe and the exhaust pipe are installed on a horizontal driving slide, the horizontal driving slide is slidably installed on the slide groove of the cold spray inflation device through a driving structure, and a universal wheel with a self-locking function is installed at the bottom of the base.

[0009] As a preferred solution, the driving structure includes a cylinder, which is installed in a slide groove, and the pneumatic driving end of the cylinder is drivingly connected to a slider sliding in the slide groove at the bottom of the horizontal driving slide.

[0010] As a preferred solution, the lifting mechanism includes a bidirectional screw rod, which is installed in the installation groove of the base, and a screw motor connected to the bidirectional screw rod is installed at one end of the base. A movable seat is installed on the bidirectional screw rod through a screw slider, and a folding support frame is connected to the movable seat through a rotating shaft. The top of the folding support frame is hinged to the bottom of the inflatable platform; guide rods are connected to the two ends of the bottom of the inflatable platform, and the two ends of the base are passed through guide holes on the guide rods.

[0011] As a preferred solution, the cold spray inflation device is provided with a display control switch panel and a tool storage box.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] When the utility model is used for inflation, the inflating platform of the cold spray inflating device is conveniently moved by the universal wheel with a self-locking function; the bidirectional screw rod is driven by the screw motor to drive the folding support frame to support and raise the inflating platform, and the height of the inflating platform is adjusted; the high-pressure gas cylinder and the air inlet pipe of the cold spray inflating device on the inflating platform are connected by a high-pressure pipeline; the horizontal driving slide is driven by the cylinder to move horizontally outward on the cold spray inflating device until the inflating pipe is exposed; thereby, it is convenient to adjust the height and horizontal position of the inflatable device, and the inflatable device can be quickly aligned with the inflation device, which is convenient for the staff to operate the inflating, and the inflation efficiency is improved; the inflating pipe of the horizontal driving slide is connected to the three-way valve by a high-pressure pipeline, and the air inlet stop valve and the air inlet pipe are connected to the cold spray bottle.

[0014] When inflating the equipment, turn on the switch of the high-pressure gas cylinder, observe the pressure of the air inlet pressure gauge, open the air inlet stop valve, open the inflation throttle valve to adjust the inflation rate, observe the pressure of the air inlet pressure gauge, maintain the pressure of the pipeline, close the inflation throttle valve, open the three-way valve, and then open the inflation throttle valve to start inflation. The inflation speed shall not exceed 1.3MPa / min. When it is inflated to 5.5MPa, close the inflation throttle valve to maintain the pressure. If there is no abnormality, disassemble the pipeline to complete the inflation work. The inflation operation is simpler, and the valves are concentrated on an inflation table, which reduces the connection and air tightness inspection between various valves and reduces the operation time. The operation site is more regular, and the placement of equipment such as on-site trolleys is reduced, making it look less messy, improving safety, reducing the corresponding pipeline connections, and eliminating the chance of other operators stepping on the pipeline, reducing the occurrence of problems.
