Description

Technical Field

[0001] This utility model relates to a glass grabbing end rotation control device of the boom of an aerial work vehicle, belonging to the field of aerial work technology. Background Technology

[0002] To enable operators to effectively control the glass position, the overall area, weight, and length of the glass are limited. In particular, when the length of the glass exceeds 5m, the commonly used glass hoisting tools have problems such as poor stability and severe susceptibility to wind speed. During the operation, the fixed position needs to be frequently adjusted, resulting in high risk of heatstroke when manually installing glass with hoisting tools, high labor intensity, and low work efficiency in hot weather.

[0003] Chinese patent application CN212863923U discloses an aerial work platform vehicle for glass installation, which includes a platform vehicle chassis, a rotating base, a lifting arm, and a glass suction frame. The aerial work platform vehicle for glass installation also includes a coarse adjustment mechanism, a fine adjustment mechanism, and an intermediate adjustment arm connected between the coarse adjustment mechanism and the fine adjustment mechanism. The coarse adjustment mechanism is also connected to the lifting arm, and the fine adjustment mechanism is also connected to the glass suction frame.

[0004] In the aforementioned prior art, when the glass suction frame at the boom's lifting end suctions and lifts the glass and approaches the glass installation position, the glass plane and the glass installation position cannot be guaranteed to be completely parallel. This results in a tilting deviation between the glass plane and the plane of the glass installation position during glass installation. The aerial work platform or boom needs to adjust the tilt angle of the glass in the horizontal or vertical direction, and the adjustment range is relatively small. This requires high precision in operation and control technology, making it quite difficult. Utility Model Content

[0005] The purpose of this utility model is to provide a glass grabbing end rotation control device for the boom of an aerial work vehicle, which solves the problems of difficulty in quickly and easily adjusting the tilt angle of the glass plane relative to the glass mounting surface in the existing technology.

[0006] The above-mentioned technical objective of this utility model is mainly achieved through the following technical solution: a glass grabbing end rotation control device for an aerial work platform boom, comprising a connecting seat connected to the grabbing end of the aerial work platform boom, a glass suction frame at the end of the connecting seat, a connecting block at the end of the connecting seat, a fixing seat connected to the connecting block at the middle end face of the glass suction frame, a top column at the middle of the end face of the fixing seat, a sphere at the end of the top column, a mating groove that mates with and connects to the hemispherical surface of the sphere, and a positioning plate that mates with the mating groove to confine the sphere within the mating groove, wherein the connecting block can deflect relative to the sphere.

[0007] As a further preferred technical solution of this utility model, the positioning plate is provided with a limiting hole in the middle, and the limiting hole is connected with the mating groove to form a cavity that limits and surrounds a spherical surface greater than half.

[0008] As a further preferred technical solution of this utility model, an annular block is provided on the end face of the connecting block, and an annular groove is provided on the end face of the positioning plate corresponding to the periphery of the limiting hole, which is threadedly connected to the annular block.

[0009] As a further preferred technical solution of this utility model, the bottom of the connecting block is provided with at least three evenly distributed fixing cylinders corresponding to the periphery of the positioning plate, and a telescopic rod that can elastically extend and retract axially is provided inside the fixing cylinder, and a telescopic spring connected to the telescopic rod is provided inside the fixing cylinder.

[0010] As a further preferred technical solution of this utility model, the end of the telescopic rod is provided with a rotatable ball, and the end face of the fixed seat is provided with a limiting groove arranged along the movement trajectory of the ball, and the side wall of the ball abuts against the bottom surface of the limiting groove.

[0011] As a further preferred technical solution of this utility model; the limiting groove is provided with vertical parts on both sides corresponding to the two sides of the telescopic rod, the top of the vertical part is provided with a horizontal part that bends and extends toward the side wall of the telescopic rod, and the side wall of the telescopic rod is provided with a sliding rod that abuts against the bottom of the horizontal part.

[0012] Therefore, this utility model has the characteristics of adaptively rotating and adjusting the tilt offset angle of the glass plane relative to the glass mounting plane, so that the glass plane adaptively fits the glass mounting plane, making the installation simpler, and avoiding the glass from breaking due to the force of the deflection.

Detailed Implementation

[0018] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] like Figure 1 and 3 As shown, a glass-grabbing end rotation control device for an aerial work platform boom includes a connecting seat 1 connected to the lifting end of the boom. A glass suction frame 2 is provided at the end of the connecting seat 1. The lifting end of the boom is connected to the glass suction frame 2, and the boom can drive the glass suction frame 2 to lift and rotate up and down to accurately grab glass from the ground to the glass mounting surface. The glass suction frame 2 is existing technology and will not be described in detail here. A connecting block 11 is provided at the end of the connecting seat 1. A fixing seat 3 connected to the connecting block 11 is provided on the middle end face of the glass suction frame 2. The connecting seat 1 connects the lifting end of the boom to the glass suction frame 2. A top post 31 is provided in the middle of the end face of the fixing seat 3. A ball 311 is provided at the end of the top post 31, the diameter of which is larger than the diameter of the top post 31. The top post 31 is fixed to the fixing seat. 3. The sphere 311 is located at the end of the top column 31 and is integrally formed with the top column 31. The end face of the connecting block 11 is provided with a mating groove 111 that mates with and connects to the hemispherical surface of the sphere 311, and a positioning plate 32 that mates with the mating groove 111 to confine the sphere 311 within the mating groove 111. The groove shape of the mating groove 111 mates with and contacts half of the surface of the sphere 311, and the positioning plate 32 can be connected to the connecting block 11 to confine the sphere 311 within the mating groove 111, preventing the sphere 311 from falling out. This also allows the glass adsorption frame 2 to adaptively deflect and rotate relative to the connecting block 11 to adapt to the deflection angle of the glass plane relative to the glass mounting surface. Furthermore, it eliminates the need for high-precision aerial work platform control, reducing control costs. At the same time, installation is simpler, and it prevents the glass from breaking due to deflection.

[0020] like Figure 3-4As shown, the positioning plate 32 has a limiting hole 321 in the middle. The limiting hole 321 is connected to the mating groove 111 to form a cavity that limits and surrounds a spherical surface larger than half. The combination of the limiting hole 321 and the mating groove 111 in the middle of the positioning plate 32 forms a cavity larger than half a spherical surface, which surrounds and limits the sphere 311, restricting the sphere 311 from coming out. At the same time, it ensures that the connecting block 11 can rotate relative to the sphere 311 around the spherical surface. The end face of the connecting block 11 has an annular block 10. The end face of the positioning plate 32 has an annular groove 322 that is threadedly connected to the annular block 10, corresponding to the periphery of the limiting hole 321. The annular block 10 on the end face of the connecting block 11 corresponds to the annular groove 322 on the positioning plate 32, so that the positioning plate 32 can be quickly positioned through the annular block 10, ensuring the connection accuracy between the limiting hole 321 and the mating groove 111, and fixing by threads, which is convenient for assembly.

[0021] like Figure 3-4As shown, the bottom of the connecting block 11 has four evenly distributed fixing cylinders 12 corresponding to the periphery of the positioning plate 32. Five, six, or more can be provided depending on actual needs. A telescopic rod 13 that can elastically extend and retract axially is inserted inside the fixing cylinder 12. A telescopic spring 14 connected to the telescopic rod 13 is also provided inside the fixing cylinder 12. The telescopic spring 14 allows the telescopic rod 13 to elastically extend and retract axially relative to the fixing cylinder 12 within the fixing cylinder 12. This facilitates adaptation to the deflection angle of the connecting block 11 relative to the glass adsorption rack 2 when the glass adsorption rack 2 rotates, and increases the rotational support force. The structure is strong, and the elastic force makes the deflection more stable and reliable. At the same time, it avoids the glass adsorption rack 2 from becoming unstable and loosening before the glass is installed, which would affect the normal installation of the glass. The end of the telescopic rod 13 is equipped with a rotatable ball 131, and the end face of the fixed base 3 is equipped with a limiting groove 33 that is set along the movement trajectory of the ball 131. The side wall of the ball 131 abuts against the bottom surface of the limiting groove 33. When the glass adsorption rack 2 rotates relative to the connecting block 11, the fixed cylinder 12 and the telescopic rod 13 always move in a radial linear motion relative to the ball 311 during the extension and retraction process. The length direction of the limiting slide groove 33 is consistent with the movement trajectory of the telescopic rod 13. When the glass adsorption frame 2 rotates relative to the connecting block 11, the telescopic rod 13 can slide along the limiting slide groove 33 via the ball bearings 131, thereby reducing the wear of the telescopic rod 13 and the fixed seat 3, and making the sliding of the telescopic rod 13 smoother and more stable. Vertical portions 34 are provided on both sides of the limiting slide groove 33 corresponding to both sides of the telescopic rod 13. A horizontal portion 341, curved and extending towards the side wall of the telescopic rod 13, is provided at the top of the vertical portion 34. The vertical portion 34 and the horizontal portion 341 combine to form an L-shaped structure, which is located on the upper side of the slide rod 132. The lateral side forms a limiting barrier to prevent the sliding rod 132 from coming off. The side wall of the telescopic rod 13 is provided with a sliding rod 132 that abuts against the bottom of the horizontal part 341. At the same time, the sliding rod 132 can slide on the inner side of the connection between the vertical part 34 and the horizontal part 341 as the telescopic rod 13 moves, which enhances the stability of the telescopic rod 13 when it moves. It also increases the axial limiting of the telescopic rod 13, strengthens the stability of the connection structure between the connecting block 11 and the fixed seat 3, and strengthens the longitudinal support force on the ball 311 and the top column 31, preventing the top column 31 and the ball 311 from breaking due to excessive load, and strengthening the structural strength.

[0022] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
