Description

Technical Field

[0001] The invention relates to the field of tooling, and in particular to a turbine engine installation tooling. Background Art

[0002] At present, the target drone installs the engine in the following way: two people work together, one person lifts the engine, and the other person guides the engine and cables into the tail port, and finally aligns the engine hole with the engine frame for fixing. The disadvantage of this installation method is that it consumes a lot of man-hours, and the engine installation and disassembly are frequent. One person needs to hold and protect the engine, and the other person removes the engine screws and disassembles the engine by hand.

[0003] In view of the above problems, the prior art uses a tool to assist in installing the engine. The tool has an engine clamp and a universal wheel at the bottom, and the tool is moved by the universal wheel. The tool clamps the generator by the engine clamp and then moves by the universal wheel. When the tool moves to the corresponding position, the position of the tool needs to be precisely adjusted. After the adjustment is in place, the universal wheel is locked. The prior art uses the locking structure on the universal wheel to lock it. When a person bends down to lock the universal wheel, the tool is easily moved, resulting in inaccurate positioning. Summary of the invention

[0004] In view of the above problems, the present invention proposes a turbine engine installation tool.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A turbine engine installation tool, comprising:

[0007] A base, wherein a first supporting sleeve is provided in a middle area of ​​a bottom of the base, and at least three second supporting sleeves are provided in a peripheral area of ​​a bottom of the base;

[0008] A universal wheel is installed in the peripheral area of ​​the bottom of the base, and the lowest ends of the first supporting sleeve and the second supporting sleeve are both higher than the lowest end of the universal wheel;

[0009] A first oil bag is embedded in the first supporting sleeve. In an initial state, the first oil bag is completely located inside the first supporting sleeve;

[0010] a first oil cylinder assembly connected to the first oil bag and used to expand the first oil bag and protrude out of the first supporting sleeve;

[0011] A second oil bag is embedded in the second supporting sleeve. In an initial state, the second oil bag is completely located inside the second supporting sleeve;

[0012] a second oil cylinder assembly connected to the second oil bag and used to expand the second oil bag and protrude out of the second supporting sleeve;

[0013] A vertical frame installed above the base;

[0014] A lifting seat, slidably mounted on the vertical frame;

[0015] A lifting drive assembly, used for driving the lifting seat to move up and down;

[0016] The electric clamp assembly is installed on the lifting seat and is used for clamping the turbine engine.

[0017] A method for using the turbine engine installation tool of the present application: an electric clamp assembly clamps the turbine engine, and then moves the base to the corresponding area. After preliminary adjustment of the position, the first cylinder assembly is controlled to operate so that the first oil bag expands and protrudes out of the first support sleeve and contacts the ground. At this time, the base can move but the friction force becomes larger, and fine-tuning can be performed. When the fine-tuning is in place, the second cylinder assembly is controlled to operate so that the second oil bag expands and protrudes out of the second support sleeve and contacts the ground. At this time, the base is fixed relative to the ground, and the turbine engine can be installed. After the installation is completed, the first cylinder assembly and the second cylinder assembly are operated to retract the first oil bag and the second oil bag, and the base can move.

[0018] The present application can achieve a preliminary increase in the friction between the base and the ground by arranging a first support sleeve and a first oil bag on the base, thereby facilitating fine-tuning the position of the base. The second support sleeve and the second oil bag can position the base after being adjusted into place. Compared with the existing locking method, there is no need to lock the universal wheel, the position of the base is accurate and reliable, and the installation operation of the turbine engine is convenient.

[0019] In one embodiment of the present invention, the universal wheel includes a connecting rod connected to the base, and a pressure sensor is installed in the connecting rod, or a pressure sensor is installed between the connecting rod and the base.

[0020] The pressure sensor can be set to feedback the working state of the oil bag. Specifically, when the first oil bag expands, the value of the pressure sensor becomes smaller. It can be set that the first oil bag works until the values ​​of all pressure sensors are less than the first threshold value, and then the expansion stops. When the second oil bag expands, the value of the pressure sensor continues to decrease until the values ​​of all pressure sensors are 0 or less than the second threshold value (the second threshold value is less than the first threshold value), at which time the second oil bag stops expanding.

[0021] In one embodiment of the present invention, the vertical frame is rotatably mounted on the base, and the turbine engine installation tool further includes:

[0022] An electric telescopic element is fixed to the bottom of the base, and the electric telescopic element has a positioning rod passing through the base. The positioning rod is used to support the lower part of the vertical frame to keep the vertical frame at a corresponding angle.

[0024] In one embodiment of the present invention, the upper left and right sides of the vertical frame are provided with handles, and the vertical frame is also provided with a control switch.

[0025] The handle can be used to push the whole body to move, and when the positioning rod is not locked to the vertical frame, it is convenient to adjust the left and right angles of the vertical frame. The control switch is used to control the operation of the cylinder assembly, electric telescopic element, lifting drive assembly, electric clamp assembly and other action mechanisms.

[0026] In one embodiment of the present invention, the bottom of the first oil bag and the bottom of the second oil bag both have a wear-resistant and drag-enhancing layer.

[0027] Providing a wear-resistant and drag-enhancing layer can increase the service life of the oil bag.

[0028] In one embodiment of the present invention, the lifting seat has a threaded hole, and the lifting drive assembly includes:

[0029] A vertical slide rail is arranged on the vertical frame, and the lifting seat is slidably mounted on the vertical slide rail through a slider;

[0030] A screw rod is rotatably mounted on the vertical frame and is parallel to the vertical slide rail, and the screw rod passes through the threaded hole of the lifting seat and is engaged with the threaded hole;

[0031] The driving motor is used to drive the screw rod to rotate and drive the lifting seat to move up and down.

[0032] In one embodiment of the present invention, the electric clamp assembly includes:

[0033] A lower arc-shaped support block is fixed on the lifting seat;

[0034] An upper arc-shaped support block is movably arranged on the lifting seat, and the upper arc-shaped support block cooperates with the lower arc-shaped support block to clamp the turbine engine;

[0035] The electric lifting element is used to drive the upper arc-shaped support block to move up and down.

[0036] In one embodiment of the present invention, the base is rectangular, and there are four second supporting sleeves, which are respectively disposed at the four corners of the base.

[0037] In one embodiment of the present invention, there are four universal wheels, which are respectively disposed at the four corners of the base.
