Description

Technical Field

[0001] The present invention relates to the field of transportation, and specifically to a device for hoisting a curved skin. Background Art

[0002] The nose skin is a curved skin. There are mainly two ways to assemble the nose skin. One is that the operator manually lifts the nose skin onto the assembly jig, and the other is to use mechanical methods such as hanging and sling bundling to hoist the nose skin onto the assembly jig. Due to the curved shape of the nose skin, the above two assembly methods have problems such as low assembly efficiency, easy damage to the nose skin during the assembly process, and potential safety hazards to the operator.

[0003] The patent with the application publication number CN 118372983 A discloses a general tooling cart for disassembling and assembling aircraft skins in the field. It includes a moving base, a lifting tool frame is arranged on the moving base, a rotation adjustment component is arranged in the lifting tool frame, several mounting brackets are arranged on the rotation adjustment component, walking components are sleeved on the front and rear sides of the mounting brackets, and a skin adsorption component is fixedly connected to the bottom end of the walking component. This general tooling cart can realize the adsorption disassembly and assembly of different curved wing skins, but the moving base and the lifting tool frame are prone to interference with the aircraft skin, which is not convenient for the installation of the aircraft skin. In addition, the skin adsorption component includes a suction cup, and the suction cup is hinged to the telescopic end of the electric telescopic rod through a ball hinge, which is not convenient for automatically adjusting the position of the suction cup. For curved skins with irregular shapes, it is difficult to ensure that each skin adsorption component automatically and firmly adsorbs and fixes to the curved skin. Summary of the Invention

[0004] The present invention provides a suction cup type curved skin hoisting device, aiming to improve the flexibility, firmness and reliability of the curved skin being adsorbed and fixed by multiple suction cups.

[0005] The technical solution adopted by the present invention is: a suction cup type curved skin hoisting device, including a longitudinal beam, a frame is connected to the longitudinal beam, a lifting member is provided on the frame, at least two cross beams are installed at intervals along the length direction of the longitudinal beam, and a suction cup is connected to each end of each cross beam. One end or both ends of at least one cross beam are connected to the suction cup through an adjustment assembly; the adjustment assembly includes an adjustment rod, a first connecting member, a second connecting member, a first telescopic rod and a second telescopic rod. It is assumed that the longitudinal beam is placed on a horizontal plane and each cross beam is horizontally arranged. Then, a first connecting member is fixed vertically at the end of the cross beam. The upper end of the first connecting member is rotatably connected to the adjustment rod, and the lower end of the first connecting member is rotatably connected to the first telescopic rod. The position of the adjustment rod far from the first connecting member is rotatably connected to one end of the first telescopic rod far from the first connecting member. The adjustment rod, the first connecting member and the first telescopic rod form a first adjustment ring. The end of the adjustment rod far from the first connecting member is rotatably connected to the second connecting member. The upper end of the second connecting member is rotatably connected to one end of the second telescopic rod, and the other end of the second telescopic rod is rotatably connected to the position of the adjustment rod close to the first connecting member. The adjustment rod, the second connecting member and the second telescopic rod form a second adjustment ring. The first adjustment ring and the second adjustment ring are respectively located below and above the adjustment rod, and the first adjustment ring and the second adjustment ring are in the same vertical plane. The suction cup is fixedly connected to the second connecting member and is located below the second connecting member.

[0006] In order to balance the forces on the suction cups at both ends of the same cross beam, further: the structures of the two ends of a single cross beam connected to the suction cups are the same.

[0007] After the curved skin is hoisted to the target position, it may be necessary to adjust the posture and then place it on the assembly jig. In order to quickly and safely adjust the posture of the curved skin after hoisting through the present invention, further: both ends of the frame are rotatably connected to the longitudinal beam. The longitudinal beam is fixedly connected with a support rod. One end of the support rod far from the longitudinal beam is connected to the frame through a third telescopic rod. Both ends of the third telescopic rod are respectively rotatably connected to the support rod and the frame.

[0008] By telescoping the third telescopic rod, the longitudinal beam can be controlled to rotate around its axis, thereby adjusting the posture of the curved skin after hoisting. In order to optimize the forces on the support rod and the third telescopic rod, further: the longitudinal beam and the frame are in the same plane, the support rod is perpendicular to the longitudinal beam, and the plane corresponding to the longitudinal beam and the frame is perpendicular to the plane corresponding to the third telescopic rod and the support rod.

[0009] In order to adjust the distance between adjacent suction cups in the length direction of the longitudinal beam by adjusting the installation position of the cross beam on the longitudinal beam, further: a plurality of cross beam installation positions are arranged at intervals along the length direction of the longitudinal beam, and the cross beam is fixedly installed at the cross beam installation position of the longitudinal beam.

[0010] The longitudinal beam can be an integral whole or consist of at least two sections connected in series. In order to adjust the spacing between adjacent suction cups in the longitudinal direction of the longitudinal beam by adjusting the length of the longitudinal beam, further: the longitudinal beam consists of at least two sections connected in series, and the connection length between adjacent two sections is adjustable, and at least one cross beam is installed on each section.

[0011] In order to quickly adjust the spacing between the suction cups at both ends of the cross beam, further: at least one end of the two ends of the cross beam is provided with a fourth telescopic rod, the telescopic direction of the fourth telescopic rod is consistent with the length direction of the cross beam, and the suction cup is installed at the telescopic end of the fourth telescopic rod.

[0012] In order to facilitate the adjustment of the lengths of the telescopic rods, further: the first telescopic rod, the second telescopic rod, the third telescopic rod and the fourth telescopic rod are all electrically controlled.

[0013] In order to facilitate the control of the telescopic rods and the suction cups, further: an electrical control box, a battery installation box and a suction cup control box are also installed on the longitudinal beam or the frame, the first telescopic rod, the second telescopic rod, the third telescopic rod and the fourth telescopic rod are all electrically connected to the battery installation box and the electrical control box, and each suction cup is electrically connected to the suction cup control box.

[0014] The beneficial effects of the present invention are: the first telescopic rod can adjust the shape of the first adjusting ring through telescopic changes, and the second telescopic rod can adjust the shape of the second adjusting ring through telescopic changes, so as to flexibly adjust the angle, posture and position of the suction cup. Set the first connecting piece to be vertical and fixed, and through the mutual cooperation of the first telescopic rod and the second telescopic rod, the suction cup can be adjusted for lifting, rotating towards the direction close to the longitudinal beam, and rotating towards the direction away from the longitudinal beam. The adjusting components at both ends of the cross beam are independent of each other, and the first telescopic rod and the second telescopic rod of the adjusting component are also independent of each other. Therefore, according to the shape of the curved surface skin, the angles, postures and positions of each suction cup can be adjusted independently, flexibly and accurately, so that each suction cup can closely fit the curved surface skin and firmly adsorb it, realizing the uniform force on the curved surface skin, thereby ensuring the safety of the curved surface skin during hoisting. The present invention can adapt to curved surface skins of different shapes and sizes, and has high versatility and practicability.

[0015] The third telescopic rod can push or pull the support rod through telescopic movement, driving the longitudinal beam to rotate around its axis direction, thereby adjusting the posture of the whole device. After the curved surface skin is hoisted to the target position, the posture of the curved surface skin after hoisting can be adjusted quickly and safely, and then placed on the assembly jig, avoiding the safety hazards existing in the manual placement of the curved surface skin by the operator.

Detailed implementation manners

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] The sucker - type curved skin hoisting device of the present invention is used to adsorb and fix the curved skin, and then cooperate with a hoisting device to hoist the skin to a target position. As Figures 1 to 4 shown, the sucker - type curved skin hoisting device includes a longitudinal beam 1, and a frame 2 is connected to the longitudinal beam 1. The longitudinal beam 1 and the frame 2 play the role of a skeleton. A lifting member 3 is provided on the frame 2. The lifting member 3 is generally a lifting ring or a hook, etc., for example, a lifting ring with an oblong hole. The lifting member 3 can be one or multiple, for example, 2 - 3.

[0022] At least two cross beams 4 are installed at intervals along the length direction of the longitudinal beam 1. Both ends of each cross beam 4 are respectively connected to a sucker 5. The sucker 5 is used to adsorb and fix the skin. There are multiple suckers 5 to adsorb and fix the skin from multiple positions. Among the multiple cross beams 4 installed on the longitudinal beam 1, at least one cross beam 4 at any one end or both ends is connected to the sucker 5 through an adjusting assembly 6. The structures of the two ends of the same cross beam 4 connected to the sucker 5 can be the same or different. In order to balance the forces on the suckers 5 at both ends of the same cross beam 4, the structures of the two ends of a single cross beam 4 connected to the sucker 5 are the same. For example, referring to Figure 1 and Figure 2 , both ends of each cross beam 4 installed on the longitudinal beam 1 are connected to the sucker 5 through an adjusting assembly 6. Another example, referring to Figure 3 and Figure 4 , among the multiple cross beams 4 installed on the longitudinal beam 1, both ends of some cross beams 4 are connected to the sucker 5 through an adjusting assembly 6, and both ends of the other part of the cross beams 4 are directly connected to the sucker 5.

[0023] The adjusting assembly 6 is used to adjust the position of the sucker 5 relative to the cross beam 4, so as to meet the requirements for adsorbing and fixing the curved skin. Referring to Figures 1 to 5 , especially Figure 5, the adjusting assembly 6 includes an adjusting rod 6-1, a first connecting member 6-2, a second connecting member 6-3, a first telescopic rod 6-4 and a second telescopic rod 6-5. To clearly describe the composition and connection relationship of the adjusting assembly 6, it is assumed that the longitudinal beam 1 is placed on a horizontal plane and each cross beam 4 is horizontally arranged. Then, the first connecting member 6-2 is fixed at the end of the cross beam 4. The first connecting member 6-2 is arranged vertically. The upper two ends of the first connecting member 6-2 are rotatably connected to the adjusting rod 6-1, and the lower end of the first connecting member 6-2 is rotatably connected to the first telescopic rod 6-4. The position of the adjusting rod 6-1 far from the first connecting member 6-2 is rotatably connected to one end of the first telescopic rod 6-4 far from the first connecting member 6-2. The adjusting rod 6-1, the first connecting member 6-2 and the first telescopic rod 6-4 form a first adjusting ring. The first telescopic rod 6-4 can be telescoped, thereby changing the shape of the first adjusting ring. To facilitate controlling the length of the first telescopic rod 6-4, the first telescopic rod 6-4 is preferably electrically controlled, that is, the length of the first telescopic rod 6-4 is controlled by electricity. The end of the first telescopic rod 6-4 is directly rotatably connected to the adjusting rod 6-1, or an ear seat is fixedly arranged at the position of the adjusting rod 6-1 far from the first connecting member 6-2, and the end of the first telescopic rod 6-4 is rotatably connected to the ear seat.

[0024] One end of the adjusting rod 6-1 far from the first connecting member 6-2 is rotatably connected to the second connecting member 6-3. The upper end of the second connecting member 6-3 is rotatably connected to one end of the second telescopic rod 6-5. The other end of the second telescopic rod 6-5 is rotatably connected to the position of the adjusting rod 6-1 close to the first connecting member 6-2. The adjusting rod 6-1, the second connecting member 6-3 and the second telescopic rod 6-5 form a second adjusting ring. The second telescopic rod 6-5 can be telescoped, thereby changing the shape of the second adjusting ring. To facilitate controlling the length of the second telescopic rod 6-5, the second telescopic rod 6-5 is preferably electrically controlled, that is, the length of the second telescopic rod 6-5 is controlled by electricity. The end of the second telescopic rod 6-5 is directly rotatably connected to the adjusting rod 6-1, or an ear seat is fixedly arranged at the position close to the first connecting member 6-2, and the end of the second telescopic rod 6-5 is rotatably connected to the ear seat.

The suction cup 5 is fixedly connected to the second connecting member 6-3 and is located below the second connecting member 6-3.

The second telescopic rod 6-5 can adjust the shape of the second adjusting ring through telescopic changes, and the adjustment and control of the first telescopic rod 6-4 and the second telescopic rod 6-5 do not affect each other, so as to flexibly adjust the posture and position of the suction cup 5, and the adjustment range of the suction cup 5 is large, which can adapt to curved skins of different shapes and sizes, and has high versatility.

[0026] After the curved skin is hoisted to the target position, it may be necessary to adjust the attitude of the curved skin and then place it on the assembly jig. In order to quickly and safely adjust the attitude of the curved skin after hoisting through the present invention and avoid the safety hazards existing in the manual placement of the curved skin by the operator, both ends of the frame 2 are rotatably connected to the longitudinal beam 1, that is, the frame 2 can rotate around the longitudinal beam 1. The longitudinal beam 1 is fixedly connected with a support rod 7-1. One end of the support rod 7-1 far from the longitudinal beam 1 is connected to the frame 2 through a third telescopic rod 7-2. Both ends of the third telescopic rod 7-2 are respectively rotatably connected to the support rod 7-1 and the frame 2. The third telescopic rod 7-2, a part of the support rod 7-1 and the frame 2 form a third adjustment ring. The third telescopic rod 7-2 can be telescopic, thereby changing the shape of the third adjustment ring, enabling the longitudinal beam 1 to rotate around its axis, and thus adjusting the attitude of the curved skin. There can be only one third adjustment ring, or multiple third adjustment rings can be provided. In order to facilitate the control of the length of the third telescopic rod 7-2, the third telescopic rod 7-2 is preferably electrically controlled, that is, the length of the third telescopic rod 7-2 is controlled by electricity. Both ends of the third telescopic rod 7-2 are directly rotatably connected to the support rod 7-1 and the frame 2, or mounting seats are respectively arranged on the support rod 7-1 and the frame 2, and both ends of the third telescopic rod 7-2 are rotatably connected to the mounting seats. In order to optimize the force on the third adjustment ring, the longitudinal beam 1 and the frame 2 are in the same plane, the support rod 7-1 is perpendicular to the longitudinal beam 1, and the planes corresponding to the longitudinal beam 1 and the frame 2 are perpendicular to the planes corresponding to the third telescopic rod 7-2 and the support rod 7-1.

[0027] After the cross beam 4 is installed on the longitudinal beam 1, the position of the cross beam 4 on the longitudinal beam 1 is fixed and non-adjustable, or the position of the cross beam 4 on the longitudinal beam 1 is adjustable. In order to adjust the spacing between adjacent suction cups 5 in the length direction of the longitudinal beam 1 by adjusting the installation position of the cross beam 4 on the longitudinal beam 1, a plurality of cross beam installation positions are arranged at intervals along the length direction of the longitudinal beam 1, and the cross beam 4 is fixedly installed at the cross beam installation position of the longitudinal beam 1. For example, installation holes are arranged at intervals along the length direction of the longitudinal beam 1, and the cross beam 4 is installed on the longitudinal beam 1 through two hoop sets arranged up and down and bolts, and the two hoop sets arranged up and down are perpendicular to each other.

[0028] The longitudinal beam 1 can be an integral body, or can be formed by at least two sections connected in series. The length of the longitudinal beam 1 can be fixed, or can be adjustable. In order to adjust the spacing between adjacent suction cups 5 in the length direction of the longitudinal beam 1 by adjusting the length of the longitudinal beam 1, the longitudinal beam 1 is formed by at least two sections connected in series, and the connection length between adjacent two sections is adjustable, and at least one cross beam 4 is installed on each section. By extending the overlapping length of adjacent two sections, the total length of the longitudinal beam 1 can be shortened, and by reducing the overlapping length of adjacent two sections, the total length of the longitudinal beam 1 can be extended. The longitudinal beam 1 is generally straight, or can be curved or bent. For example, referring to Figure 1 and Figure 4 , the longitudinal beam 1 is bent, and the plane corresponding to the longitudinal beam 1 coincides with the plane corresponding to the frame 2.

[0029] In order to quickly adjust the distance between the two suction cups 5 at both ends of the cross beam 4, at least one end of the two ends of the cross beam 4 is provided with a fourth telescopic rod. The telescopic direction of the fourth telescopic rod is consistent with the length direction of the cross beam 4, and the suction cup 5 is installed at the telescopic end of the fourth telescopic rod. When the suction cup 5 is connected to the cross beam 4 through the adjusting assembly 6, the first connecting member 6-2 is fixedly connected to the telescopic end of the fourth telescopic rod. The fourth telescopic rod can be telescopic, thereby changing the distance between the suction cup 5 and the longitudinal beam 1. In order to facilitate the control of the length of the fourth telescopic rod, the fourth telescopic rod is preferably electrically controlled, that is, the length of the fourth telescopic rod is controlled by electricity.

[0030] In order to facilitate the control of each telescopic rod and each suction cup 5, an electrical control box 8, a battery installation box 9 and a suction cup control box are also installed on the longitudinal beam 1 or the frame 2.
