Description

TECHNICAL FIELD

[0001] The utility model relates to the field of aircraft ground maintenance equipment, especially to a static pressure hole shielding device for aircraft paint surface treatment. BACKGROUND

[0002] Aircraft skin paint surface treatment is one of aircraft ground maintenance projects, and when aircraft skin paint surface treatment is carried out, aircraft components exposed on the surface of the aircraft (such as static pressure holes, antennas, pitot tubes, etc.) need to be shielded. For example, in order to maintain the smoothness of the static pressure hole area and prevent the static pressure hole from being blocked, or to avoid that the rust removal liquid or paint corrodes the static pressure hole, the static pressure hole needs to be shielded before paint surface treatment.

[0003] The static pressure hole of a common passenger aircraft is about 3 meters high from the ground. In the past, when paint surface treatment was carried out, a climbing device was used to climb to a high position, and then shielding objects were pasted around the static pressure hole area. After the paint surface treatment was completed, the shielding objects had to be removed by climbing to the high position again. The previous operation mode has the following defects:

[0004] 1) The adhesive tape can only be used once, which wastes resources and leaves adhesive marks;

[0005] 2) The static pressure hole is located at a high position, and a climbing device needs to be used, which is not safe and low in efficiency. INVENTION CONTENTS

[0006] The purpose of the case is to provide a static pressure hole shielding device for aircraft paint surface treatment to overcome the shortcomings and deficiencies in the prior art.

[0007] In order to achieve the above purpose, the case is implemented through the following technical solutions:

[0009] The high-position suction assembly comprises a suction disc seat and a pressing suction disc mounted on the suction disc seat;

[0010] The suction disc seat comprises a containing seat and a high-position docking head, and the containing seat and the high-position docking head are connected into one body through a high-position connecting plate. A central hole is provided on the containing seat, and the central hole is used to mount and press the suction disc;

[0011] The pressing suction disc comprises a suction disc body and a cam handle provided at the tail end of the suction disc body;

[0012] The low-position control assembly comprises a main support rod, a low-position docking head, a secondary control rod, an upper control plate, and a lower control plate;

[0013] The main support rod is screw-connected with the low-position docking head at the top;

[0014] The low-position butt joint is provided with a low-position butt joint groove on the side surface, and an upper side wall of the low-position butt joint groove is provided with a low-position butt joint notch; the low-position butt joint groove corresponds to the high-position butt joint, and the low-position butt joint notch corresponds to the high-position connecting plate, so that the low-position butt joint groove can cover the high-position butt joint for butt joint, and after butt joint, the high-position butt joint is embedded in the low-position butt joint groove, and the high-position connecting plate is embedded in the low-position butt joint notch.

[0015] The auxiliary control rod is movably arranged on one side of the main supporting rod.

[0016] The upper control plate and the lower control plate are arranged in the same direction and are fixedly arranged on the top of the auxiliary control rod in an upper-lower interval, and the interval between the upper control plate and the lower control plate is adapted to the opening and closing degree of the cam handle of the pressing suction disc when the cam handle is actuated; when the auxiliary control rod is pushed upward or pulled downward, the upper control plate and the lower control plate can actuate the cam handle of the pressing suction disc.

[0017] Further, a pair of high-position limiting ears are symmetrically arranged on the side surface of the accommodating seat.

[0018] Further, a pair of low-position limiting ears are further arranged on the top surface of the low-position butt joint, and the low-position limiting ears correspond to the high-position limiting ears.

[0019] Further, the low-position control assembly further comprises an auxiliary rod connecting plate, both ends of the auxiliary rod connecting plate are provided with sleeve holes, and the sleeve hole at one end of the auxiliary rod connecting plate is used for being fixedly sleeved on the main supporting rod, and the sleeve hole at the other end is used for movably inserting the auxiliary control rod.

[0020] Preferably, a pair of limiting blocks are arranged on the auxiliary control rod on the opposite sides of the auxiliary rod connecting plate.

[0021] Preferably, two auxiliary rod connecting plates are arranged, and the two auxiliary rod connecting plates are arranged in the same direction and are fixedly arranged on the main supporting rod in an upper-lower interval.

[0022] Preferably, the auxiliary control rod is two sections of screw type.

[0023] Preferably, one end of the upper control plate and the lower control plate towards the pressing suction disc is provided with an arc-shaped split.

The limit blocks can limit the up and down sliding stroke of the secondary control stick, making it easier for ground operators to accurately control the cam handle of the high-positioned pressing suction cup through the secondary control stick, thereby facilitating the locking or unlocking of the pressing suction cup.

[0041] Furthermore, if terms such as "first" or "second" are used for descriptive purposes only, they are mainly used to distinguish different devices, components or parts (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance or quantity of the indicated devices, components or parts, and should not be construed as indicating or implying relative importance.

[0042] Please also refer to Figures 1-7 A static pressure hole shielding device for aircraft paint treatment includes a high-position adsorption component a and a low-position control component b that can be docked together. The high-position adsorption component a can be controlled by the low-position control component b to adsorb and lock onto the static pressure hole of the aircraft, or to unlock from the static pressure hole, so that the operator can shield and protect the static pressure hole from the ground during paint treatment.

[0043] A high-position adsorption component a, which includes a suction cup base 1 and a pressing suction cup 2 mounted on the suction cup base 1;

[0044] The suction cup base 1 includes a receiving base 11 and a high-position connector 12. The receiving base 11 and the high-position connector 12 are connected as one unit by a high-position connecting plate 13. The receiving base 11 is provided with a central hole 111, which is used to install and press the suction cup 2. The high-position connector 12 is used to dock with the low-position control component b.

[0045] Furthermore, a pair of high-position limiting ears 112 are symmetrically arranged on the side of the receiving seat 11. The high-position limiting ears 112 are used to cooperate with the low-position control component b so that the suction cup 2 can be stably subjected to force when pressed.

[0046] The suction cup 2 includes a suction cup body 21 and a cam handle 22 located at the tail end of the suction cup body 21. By moving the cam handle 22, the suction cup body 21 can be locked (attached to the target) or unlocked (separated from the target).

[0047] The low-position control component b includes a main support rod 3, a low-position connector 4, a secondary rod connecting plate 5, a secondary control rod 6, an upper control plate 7, and a lower control plate 8.

[0048] The main support rod 3 has a low-position connector 4 screwed to its top, making the main support rod 3 and the low-position connector 4 detachable and easy to disassemble and store.

[0049] The low-position connector 4 has a low-position docking groove 41 on its side, and a low-position docking notch 42 is provided through the upper side wall of the low-position docking groove 41. The low-position docking groove 41 corresponds to the high-position connector 12, and the low-position docking notch 42 corresponds to the high-position connecting plate 13. This allows the low-position docking groove 41 to fit over the high-position connector 12 for docking. After docking, the high-position connector 12 is embedded in the low-position docking groove 41, and the high-position connecting plate 13 is embedded in the low-position docking notch 42.

[0050] Furthermore, a pair of low-position limiting ears 43 are extended from the top surface of the low-position connector 4. The low-position limiting ears 43 correspond to the high-position limiting ears 112, so that the pressure can be stably applied and pressed against the high-position limiting ears 112 by the low-position limiting ears 43.

[0051] The auxiliary rod connecting plate 5 has sleeve holes at both ends, so that the sleeve hole at one end of the auxiliary rod connecting plate 5 is used to fix it on the main support rod 3, and the sleeve hole at the other end is used to movably insert the auxiliary control rod 6.

[0052] Preferably, in this embodiment, two auxiliary rod connecting plates 5 are provided, and the two auxiliary rod connecting plates 5 are arranged in the same direction and fixed to the main support rod 3 with an upper and lower gap.

[0053] The secondary control lever 6 is a two-section screw-connected type, which makes the secondary control lever 6 detachable and easy to disassemble and store; the secondary control lever 6 is movably inserted into the sleeve hole on the secondary lever connecting plate 5, so that the secondary control lever 6 can slide up and down or rotate within the sleeve hole of the secondary lever connecting plate 5.

[0054] Preferably, in this embodiment, a pair of limiting blocks 61 are provided on the secondary control lever 6 on opposite sides of the first secondary lever connecting plate 5. The pair of limiting blocks 61 can limit the up and down sliding stroke of the secondary control lever 6, making it easier for ground workers to accurately control the cam handle 22 of the pressing suction cup 2 through the secondary control lever 6, thereby conveniently controlling the locking or unlocking of the pressing suction cup 2.

[0055] The upper control panel 7 and the lower control panel 8 are arranged in the same direction and fixedly positioned at an interval on the top of the auxiliary control lever 6. The distance between the upper control panel 7 and the lower control panel 8 is adapted to the opening and closing degree of the cam handle 22 of the suction cup 2 when it is turned. When the operator on the ground pulls down the auxiliary control lever 6, the cam handle 22 of the suction cup 2 can be turned down through the upper control panel 7. When the operator on the ground pushes up the auxiliary control lever 6, the cam handle 22 of the suction cup 2 can be turned up through the lower control panel 8. This allows the operator to control the locking or unlocking state of the suction cup 2, which is in a high position, simply by standing on the ground.

[0056] Preferably, in this embodiment, both the upper control plate 7 and the lower control plate 8 have an arc-shaped fork 71 at the end facing the pressing suction cup 2, so that during actual operation, if the upper control plate 7 and the lower control plate 8 are not completely aligned with the cam handle 22 of the pressing suction cup 2, they can still contact and control the cam handle 22 through the extended arc-shaped fork 71, thereby improving the effectiveness and stability of operation.

[0057] Preferably, in this embodiment, the receiving seat 11 is square and the high-position connector 12 is round.

[0058] As a preferred embodiment, in this embodiment, the lower end of the main support rod 3 is also provided with an anti-slip sleeve 31.

[0059] Preferably, in this embodiment, a rotating handle 62 is also provided at the lower end of the secondary control lever 6.

[0060] The actual operating procedure for this device is as follows:

[0061] 1) Before the aircraft skin is painted, the ground workers connect the high-position adsorption component a and the low-position control component b together, so that the low-position docking groove 41 fits the high-position docking connector 12 and the high-position connecting plate 13 is embedded in the low-position docking notch 42.

[0062] 2) The operator holds the main support rod 3 to lift the high-position adsorption component a and makes the suction cup body 21 of the pressing suction cup 2 stick to the static pressure hole of the aircraft.

[0063] 3) The operator adjusts the auxiliary control lever 6 by rotating or moving it up and down, so that the upper control plate 7 and the lower control plate 8 are respectively aligned with the upper and lower sides of the cam handle 22 of the pressing suction cup 2, and moves the control cam handle 22 by pushing or pulling the upper control plate 7 and the lower control plate 8, so that the pressing suction cup 2 is attached and locked on the aircraft skin on the outer periphery of the static pressure hole.

[0064] 4) The operator adjusts the auxiliary control lever 6 by rotating or moving it up and down, so that the upper control plate 7 and the lower control plate 8 are disengaged from the cam handle 22 of the pressing suction cup 2, and the docking of the high-position adsorption component a and the low-position control component b is released by the main support rod 3, and the low-position control component b is removed while the high-position adsorption component a remains adsorbed on the aircraft skin to cover the static pressure hole.

[0065] 5) The workers began applying paint to the aircraft skin;

[0066] 6) After the paint treatment is completed, repeat steps 1 and 3 above to unlock the suction cup 2 and detach it from the aircraft skin;

[0067] 7) The operator holds the main support rod 3 and removes the high-position adsorption component a and the low-position control component b that are connected together, and then disassembles and stores them.

[0068] Compared with the prior art, the beneficial effects of this utility model are as follows: The static pressure hole shielding device used in the aircraft paint treatment of this case controls the locking or unlocking of the high-positioned suction cup through the cooperation of the main support rod and the auxiliary control rod. The operator only needs to operate on the ground to shield and protect the high-positioned static pressure hole with the suction cup, which effectively improves the efficiency of aircraft skin paint treatment.

[0069] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
