Description

Technical Field

[0001] The present invention belongs to the technical field of workshop conveying equipment, and particularly relates to a belt-type scissor lift and mobile platform for production workshop transportation. Background Art

[0002] In the transportation links of different processes in a production workshop, the scissor lift mechanism, as a commonly used vertical lifting device, can flexibly adapt to the different height requirements of a single process, while the scissor mobile platform plays a transfer role between various processes. Traditional scissor lift mechanisms mostly adopt hydraulic drive or electric screw drive methods. However, hydraulic drive has many drawbacks. On the one hand, the hydraulic system occupies a large space, and the installation and maintenance costs are relatively high; on the other hand, when the hydraulic pump runs continuously, the energy consumption is relatively high, and the precision control is limited. It is also easily interfered by the oil temperature fluctuation and leakage problems, resulting in unstable lifting positioning accuracy. Although the electric screw drive scheme has improved in terms of precision, the friction loss between the screw and the nut is relatively large. It is prone to wear after long-term use and requires frequent replacement of components. The linear speed of the screw drive is limited by the motor speed and is difficult to meet the requirements of high-speed lifting. At the same time, the prior art is also exploring the use of scissor mechanisms driven by chains or steel cables. However, for the scissor mechanism driven by chains or steel cables, its transmission smoothness is poor, and it is prone to jitter or slipping phenomena, especially the reliability is insufficient under heavy load conditions.

[0003] Based on the problems existing in the above traditional drive methods and the deficiencies of the prior art, it is urgent to design a new type of scissor lift and mobile platform, which while retaining the advantages of the scissor structure, overcomes the defects of the traditional drive methods, and realizes the lifting function that is efficient, low-noise, lightweight and precisely controllable. For this reason, the present invention proposes a belt-type scissor lift and mobile platform for production workshop transportation. Summary of the Invention

Detailed implementation manners

[0023] For a clearer understanding of the technical features, objectives, and beneficial effects of the present invention, the technical solutions of the present invention will be described in detail below, but it should not be construed as a limitation on the implementable scope of the present invention.

[0024] As Figures 1-4 shown, an embodiment of the present invention provides a belt-type scissor lift and mobile platform for use in a production workshop, including a base 10, a carrier 70, two groups of scissors arms, two groups of secondary scissors plate assemblies, a belt assembly, an anti-falling component, a transportation control component, and a motor 80; both the base 10 and the carrier 70 are provided with two symmetrically arranged guide grooves 11.

[0025] As Figure 1 and Figure 2 shown, as a preferred embodiment of the present invention, each group of the scissors arms includes a first arm 20 and a second arm 21 that are cross-hinged, and the second arm 21 is arranged inside the first arm 20; rollers are rotatably connected to the bottom ends of the two first arms 20 and the top ends of the two second arms 21, facilitating sliding in the guide grooves 11; the rollers at the bottom ends of the two first arms 20 are respectively slidably connected to the two guide grooves 11 of the base 10, and the top ends are respectively hinged to the lower part of the carrier 70; the bottom ends of the two second arms 21 are respectively hinged to the base 10, and the rollers at the top ends are respectively slidably connected to the two guide grooves 11 of the carrier 70.

[0026] To ensure that the speed of the carrier 70 tends to be uniform during the ascending process, thereby improving the running stability, arc plates 22 are fixedly connected to both the first arm 20 and the second arm 21 (taking Figure 1 the direction as a reference, an arc plate 22 is fixed on the inner side of the upper right part of the first arm 20, and an arc plate 22 is fixed on the lower right part of the second arm 21), and the arc plate 22 on the first arm 20 and the arc plate 22 on the second arm 21 are symmetrically arranged horizontally with the hinge point of the first arm 20 and the second arm 21 as the axis; the arc plate 22 is designed with a convex surface, and the convex side of the arc plate 22 faces the outside of the scissors arm, so that the carrier 70 ascends at a uniform speed.

[0027] In the embodiment of the present invention, two fixing frames are provided on the base 10, and the bottom ends of the two second arms 21 are respectively hinged to the two fixing frames.

[0028] As Figure 1 shown, as a preferred embodiment of the present invention, each group of secondary shear plate assemblies includes a first shear plate 41, a second shear plate 42, and a shear plate fixing roller group 40, and the first shear plate 41 and the second shear plate 42 are arranged in a cross manner; the top ends of the two first shear plates 41 are respectively hinged to the two second arms 21, and the bottom ends are respectively hinged to the lower ends of the shear plate fixing roller group 40; the bottom ends of the two second shear plates 42 are respectively hinged to the two first arms 20, and the top ends are respectively hinged to the upper ends of the shear plate fixing roller group 40.

[0029] As Figure 1 and Figure 3 shown, as a preferred embodiment of the present invention, the belt assembly includes two belts 30, a belt reel 31, a belt fixing rod group 32 (including two belt fixing rods), two groups of first belt pulley groups 33, a second belt pulley group 34, and a belt pulling plate 35; both ends of the belt 30 are respectively fixed to the belt reel 31 and the belt pulling plate 35, and the belt 30 is wound clockwise around the belt reel 31, the belt fixing rod group 32, the first belt pulley group 33, the second belt pulley group 34, and the belt pulling plate 35 in sequence; the belt reel 31 is rotatably connected to the base 10; the belt fixing rod group 32 is rotatably connected to the base 10; each group of the first belt pulley groups 33 includes two first belt pulleys and two wheel rods, the two first belt pulleys are respectively rotatably connected to the two wheel rods, and the wheel rods are fixed to the shear plate fixing roller group 40; the second belt pulley group 34 includes a main shaft, two rollers, two second belt pulleys, and a hydraulic cylinder trunnion, the outermost sides of both sides of the main shaft are rotatably connected with the rollers, the two rollers are respectively in contact with the arc surfaces of the arc plates 22 of the first arm 20 and the second arm 21, between the two rollers are the two second belt pulleys, the second belt pulleys penetrate through the main shaft and are rotatably connected thereto, between the two second belt pulleys is the hydraulic cylinder trunnion, and the hydraulic cylinder trunnion is fixedly connected at the central plane of the main shaft; the belt pulling plate 35 is fixed to the shear plate fixing roller group 40.

[0030] The output end of the motor 80 is connected to the input end of the belt reel 31, and the motor 80 is fixedly arranged on the base 10. Different from the existing lifting mechanism, the present invention uses the motor 80 to drive the belt assembly to drive the scissors arm.

[0031] To prevent the second pulley set 34 from slipping on the scissors arm, the roller of the second pulley set 34 in contact with the arc plate 22 is designed with a concave surface, and the concave surface design of the roller is adapted to the convex surface design of the arc plate 22.

[0032] To avoid the horizontal slippage of the lifting mobile platform caused by different forces of the first pulley set 33 and the second pulley set 34 in the horizontal direction and ensure the balance of forces of the lifting mobile platform in the horizontal direction, the hinge point of the first arm 20 and the bearing platform 70 is on the same vertical line as the hinge point of the second arm 21 and the base 10, so that one side of the scissors arm is always on the same vertical line during the lifting of the lifting mobile platform. With the positions of the two hinge points on one side of the scissors arm unchanged, to ensure the smooth opening and closing of the scissors plate and the rising of the bearing platform 70, the present invention sets a guide groove 11 at the corresponding positions on the left sides of the base 10 and the bearing platform 70 to facilitate the sliding of the left roller of the scissors arm.

[0033] In the embodiment of the present invention, in order to improve the service life of the belt 30 in the lifting mobile platform and keep the power of the motor 80 basically constant in the high-position working state, one side of the lifting force receiving end of the two belts 30 is designed as a secondary scissors plate. During the rising process, as the two secondary scissors plates get closer to the vertical state, their load-bearing capacity becomes greater, the force on the belt 30 becomes smaller, so that the power during the rising process is basically constant, and most of the forces are decomposed at the high position, improving the service life of the belt 30. By designing the bottom end of the first scissors plate 41 to be at the lower position in the same vertical direction as the top end of the second scissors plate 42 (relative to the scissors plate fixed roller set 40), this performance is further improved.

[0034] As Figures 1-5 shown, as a preferred embodiment of the present invention, through speed calculation and analysis, it is obtained that the angle between the tangent of the roller and the scissors arm and the horizontal plane should increase slowly with the winding radius of the belt 30, and then the arc plate 22 is increased to meet this characteristic, specifically as follows: See Figure 5 , there are the following formulas: ; ; ; ; ; Among them, is the horizontal speed of the roller, is the velocity of the roller's horizontal velocity decomposition on the scissors arm, is the velocity perpendicular to the scissors arm at the top of the scissors arm, is the decomposed vertical velocity, θ is the angle between the scissors arm and the horizontal plane during the movement, L is 1 / 2 of the length of the scissors arm (the first arm 20 or the second arm 21, and the first arm 20 and the second arm 21 have the same length), R is the roller radius, is the rotational speed of the motor 80, r is the radius of the belt 30 on the belt reel 31; L 、 and R are all unchanged, r increases as the carrier 70 rises and the belt 30 is wound up, θ also increases as the carrier 70 rises. To ensure that remains unchanged, it is necessary to make the angle between and decrease as r increases, and then increase the arc plate 22 to ensure this condition.

[0035] As Figures 1-4 shown, as a preferred embodiment of the present invention, the anti-falling component includes a hydraulic cylinder 50, an oil cylinder 51, and a hydraulic cylinder fixing component 52; the oil cylinder 51 is connected to the hydraulic cylinder 50 to provide hydraulic oil for it to ensure the normal operation of the hydraulic cylinder 50; a through hole is provided at the center of the scissors plate fixed roller group 40, one end of the hydraulic cylinder 50 passes through the through hole of the scissors plate fixed roller group 40, and the other end is hinged to the center of the second pulley group 34 through a hydraulic cylinder trunnion; the hydraulic cylinder fixing component 52 is fixedly connected to the scissors plate fixed roller group 40 and clamps the hydraulic cylinder 50.

[0036] In the embodiment of the present invention, to improve the safety of the carrier 70 and prevent accidents during falling, a hydraulic cylinder 50 is added in the middle of the two sets of scissors plate assemblies. When a falling accident causes the carrier 70 to descend rapidly, the hydraulic cylinder 50 can quickly adjust the internal pressure by virtue of its rapid response characteristics. At this time, the pressure generated inside the hydraulic cylinder 50 cancels out the gravity that causes the carrier 70 to fall, so that the carrier 70 stops in the air and avoids accidents. At the same time, during the rising process of the carrier 70, the hydraulic cylinder 50 can also ensure that the scissors plate fixed roller group 40 always rises vertically without flipping.

[0037] As Figure 1 and Figure 2As shown, as a preferred embodiment of the present invention, the transportation control assembly includes an AGV chassis 60, two sets of symmetrically arranged Mecanum wheels 61, a drive assembly 62, and a shock absorption assembly 63. The AGV chassis 60 is fixed directly below the base 10. The two sets of Mecanum wheels 61 are respectively connected to the front side and the rear side of the AGV chassis 60. The Mecanum wheels 61 are connected to the drive assembly 62 and the shock absorption assembly 63, and are connected to the control system in the AGV chassis 60. The drive assembly 62 is controlled by the control system in the AGV chassis 60.

[0038] In the embodiment of the present invention, in order to complete the automated operation of the same workpiece through different processes, the AGV chassis 60 is added, which can realize the full automation control of the workshop transportation process. In order to solve the waste of workshop space caused by the large volume of the lifting and moving platform during the moving process, the Mecanum wheels 61 are used to improve the AGV chassis 60, realizing the omnidirectional movement of the lifting and moving platform and improving the space utilization rate.

[0039] The structure of the shock absorption assembly 63 is as follows: The middle of the shock absorption bottom plate is connected to the main shaft connecting the drive assembly 62 and the Mecanum wheel 61. One end is connected to the AGV chassis frame through a hinge, and the other end is hinged to the AGV chassis 60 through a spring (since this shock absorption method is mostly used for Mecanum wheels 61 on the market at present, it will not be elaborated too much).

[0040] As Figures 1-3 As shown, as a preferred embodiment of the present invention, the base 10 only plays a supporting role. The projection of the scissor arm is two parallel lines. Therefore, for the consideration of saving space, the base 10 is designed as a rectangle. Its long side from left to right is respectively the guide groove 11, the scissor arm connection end, the belt fixing rod group 32, the belt reel 31, and the motor 80. In order to facilitate processing and ensure the balance of the scissor arm, the main structure of the carrier table 70 can be set to be the same as that of the base 10.

[0041] The working principle of the present invention is: For the belt - type scissor lift and mobile platform used for transportation in the production workshop, when the carrier 70 needs to be lifted, the motor 80 drives the belt reel 31, causing the belt 30 to wind around the belt reel 31. At this time, the length of the belt 30 from the belt pull - plate 35 to the belt reel 31 shortens. The bottoms of the two first arms 20 and the tops of the two second arms 21 slide to the right. The scissor - plate fixed - roller group 40 moves in the direction of the hinge of the scissor arms. The angle between the first scissor - plate 41 and the second scissor - plate 42 becomes larger (the right - hand angle formed with the hinge point of the first scissor - plate 41 and the second scissor - plate 42 as the boundary) and moves towards the scissor - arm direction. The second pulley group 34 moves along the scissor arm towards the hinge point of the scissor arms. The distance between the first pulley group 33 and the second pulley group 34 is reduced. The angle between the first arm 20 and the second arm 21 becomes smaller (the lower - hand angle formed with the hinge point of the first arm 20 and the second arm 21 as the boundary). The carrier 70 is lifted, thereby driving the materials placed on the carrier 70 to rise.

[0042] The above is only the preferred embodiment of the present invention. It should be noted that for those skilled in the art, without departing from the concept of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention. These will not affect the implementation effect of the present invention and the practicality of the patent.
