Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical transportation field, concretely relates to a lifting device for material tank. BACKGROUND

[0002] In the industrial production process, the vertical carrying and accurate positioning of materials are very important, which makes the lifting mechanism become the indispensable key equipment in many production links. The traditional Z-axis lifting mechanism has many deficiencies in motion stability and precision, which seriously affects the production efficiency and product quality.

[0003] On the one hand, the driving system design of the traditional lifting mechanism is relatively simple. For example, some use single chain or rope driving mode. In the long-term use process, the chain is prone to stretch deformation, the meshing precision between the chain link and the chain wheel is reduced, the rope is prone to wear and tear, and the rope is prone to wear and tear. In the winding process, the phenomenon of slipping occurs, which will cause the lifting platform to produce obvious displacement deviation in the process of rising or falling, and cannot guarantee the stable motion trajectory, thereby affecting the precision of material carrying.

[0004] On the other hand, the guide structure of the traditional lifting mechanism lacks reliability. Commonly, it is a simple combination of guide rail and sliding block. The installation precision of the guide rail is difficult to maintain for a long time. When subjected to external force interference such as equipment vibration and material impact, the guide rail is prone to deformation and displacement, which makes the sliding block on the guide rail slide or appear lateral deviation, destroys the vertical motion stability of the lifting platform, and causes the material to shake and deviate from the predetermined position during lifting. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a lifting device for material tank, which is composed of a bearing platform, a frame body and a buffer assembly. The lifting device is provided with lifting units uniformly distributed around the transportation space in the middle of the frame body, so that the bearing platform moves longitudinally and reciprocally, meeting the needs of high-precision and stable carrying of modern industrial production.

[0006] The utility model realizes the following technical scheme:

[0007] A lifting device for material tank, comprising:

[0008] A bearing platform, the upper end of the bearing platform clamping the material tank;

[0009] A frame body, the middle part of the frame body is provided with a transportation space accommodating the bearing platform, lifting units are uniformly distributed around the transportation space, the lower end of the bearing platform is connected to the lifting units, and the bearing platform moves longitudinally and reciprocally in the transportation space through the lifting units;

[0010] A buffer assembly is connected to the bottom of the transport space at one end and to the lower end of the bearing platform at the other end.

[0011] In this scheme, the bearing platform serves as the bearing part of the tank, with its upper end clamping the tank to ensure stable placement of the material during lifting. The transport space of the frame and the lifting units evenly distributed around it provide the bearing platform with the space for movement and power support, avoiding movement deviation caused by single-point driving or insufficient support, enabling the bearing platform to move stably in the longitudinal direction, thereby achieving vertical handling of the tank. The buffer assembly connected to the bottom of the transport space and the lower end of the bearing platform serves as a buffer during tank placement and lifting, effectively reducing impact and vibration, and providing multi-directional support for achieving high-precision and stable handling of materials.

[0012] As an optimization scheme of the lifting device, the buffer assembly is provided in multiple numbers and evenly distributed at the bottom of the transport space.

[0013] In this scheme, the buffer assembly is provided in multiple numbers and evenly distributed at the bottom of the transport space, which can buffer the impact generated by the bearing platform during movement in all directions. During tank placement and lifting, regardless of the position of the bearing platform or the direction of the acting force, the multiple evenly distributed buffer assemblies can effectively disperse the impact force, avoiding poor buffering effect or damage to device components caused by excessive local stress.

[0014] As an optimization scheme of the lifting device, the buffer assembly is a spring damper, and the buffer assembly is fixed to the bottom of the transport space by expansion screws.

[0015] In this scheme, the spring damper can effectively absorb the impact force generated during tank placement and lifting by virtue of its elastic properties and damping effect, buffering while avoiding excessive rebound to ensure the stability of the bearing platform movement. The expansion screw fixing method ensures the firmness and stability of the buffer assembly installation, so that it can still be in the correct position and stably perform the buffering function in the long-term working environment of bearing impact and vibration.

[0016] As an optimization scheme of the lifting device, the lifting unit includes multiple sets of guide assemblies and at least one set of driving assemblies.

[0017] Among them, multiple sets of the guide assemblies are evenly distributed around the transport space and connected to the lower end of the bearing platform.

[0018] The driving assembly is connected to the lower end of the bearing platform, and the bearing platform moves reciprocally along the guide assembly through the driving assembly.

[0019] In the scheme, multiple sets of guide assemblies are evenly distributed around the transportation space and connected to the lower end of the bearing platform, providing stable guiding effect from multiple directions when the bearing platform reciprocates, effectively limiting the degrees of freedom of the bearing platform, ensuring the linearity and accuracy of its movement trajectory, preventing instability such as deviation and shaking, and providing a reliable power source for the bearing platform by connecting the driving assembly to the lower end of the bearing platform and making it move along the guide assembly, ensuring that the tank can be lifted vertically and stably on a precise path, meeting the high-precision and high-stability requirements of industrial production for material handling.

[0020] As an optimization scheme of the lifting device, the guide assembly comprises a guide piece, a guide plate and a sliding piece.

[0021] One end of the guide plate is connected to the wall of the transportation space, and the other end of the guide plate is provided with a convex part with a radial cross-section in the shape of an I-beam, one end of the sliding piece is provided with a groove matched with the convex part, and the other end of the sliding piece is connected to the lower end of the bearing platform through the guide piece.

[0022] In the scheme, one end of the guide plate is connected to the wall of the transportation space, and the I-beam-shaped convex part is tightly matched with the groove of the sliding piece, forming a stable and precise guide structure. This structure restricts the movement of the sliding piece in a specific direction, effectively preventing the bearing platform from deviating or shaking laterally during lifting. The sliding piece is connected to the lower end of the bearing platform through the guide piece, which can smoothly transmit the guiding effect to the bearing platform, ensuring that the bearing platform reciprocates strictly according to the predetermined vertical path, thereby significantly improving the movement accuracy and stability of the lifting device.

[0023] As an optimization scheme of the lifting device, the driving assembly comprises a motor and a rack.

[0024] One end of the rack is connected to the wall of the transportation space, and the other end of the rack is provided with straight teeth. The motor is connected to the lower end of the bearing platform, and the output end of the motor is connected with a gear engaged with the rack.

[0025] In the scheme, the motor is connected to the lower end of the bearing platform, and the gear at the output end of the motor is engaged with the rack connected to the wall of the transportation space. This structure design efficiently converts the rotary motion of the motor into linear reciprocating motion of the bearing platform, providing stable power for the lifting of the tank. The straight teeth of the rack tightly match the gear, ensuring the accuracy and reliability of power transmission, precisely controlling the movement speed and displacement of the bearing platform, thereby achieving precise control of the lifting process of the tank and meeting the strict requirements of industrial production for material handling accuracy and stability.

[0026] As an optimization scheme of the lifting device, the lifting device further comprises a pair of counterweight units arranged on both sides of the frame body and connected with the bearing platform through guide wheels arranged on the frame body, and the movement direction of the counterweight units is opposite to the movement direction of the bearing platform.

[0027] In the scheme, the counterweight units arranged on both sides of the frame body and connected with the bearing platform through guide wheels have a movement direction opposite to that of the bearing platform, which can effectively balance the change of the center of gravity of the bearing platform during lifting. When the bearing platform rises or falls, the counterweight units can automatically adjust the position according to the movement state, reduce the deviation of the center of gravity caused by uneven weight distribution of the tank or change of the lifting height, enhance the stability of the entire lifting device, reduce the shaking and vibration during operation of the device, and prevent safety hazards caused by unstable center of gravity.

[0028] As an optimization scheme of the lifting device, the counterweight unit comprises a limiting plate and a counterweight.

[0029] One end of the limiting plate is connected to the side end of the frame body, the other end of the limiting plate is provided with a protruding part with a H-shaped cross section in the radial direction, the counterweight is provided with a groove matched with the protruding part, and when the bearing platform moves in the longitudinal direction, the counterweight moves along the limiting plate.

[0030] In the scheme, the limiting plate is connected to the side end of the frame body, and the H-shaped protruding part is matched with the groove of the counterweight. When the bearing platform moves in the longitudinal direction, this structure ensures that the counterweight can stably move in the opposite direction along the limiting plate. On the one hand, it effectively maintains the balance of the center of gravity of the entire device, reduces the shaking caused by the change of the position of the bearing platform, and enhances the stability during lifting. On the other hand, the precise matching of the groove and the protrusion provides reliable guidance for the movement of the counterweight, prevents it from deviating or derailing, and ensures that the counterweight unit can accurately function under different working conditions.

[0031] As an optimization scheme of the lifting device, the counterweight unit further comprises a first directional wheel set and a second directional wheel set, the first directional wheel set and the second directional wheel set are arranged in the groove of the counterweight in a spaced manner, and the rotation shaft directions of the first directional wheel set and the second directional wheel set are arranged in a perpendicular manner.

[0032] In the scheme, the first directional wheel set and the second directional wheel set are arranged in the groove of the counterweight in a spaced manner and the rotation shaft directions are arranged in a perpendicular manner. When the counterweight moves along the limiting plate, the friction between the counterweight and the limiting plate can be greatly reduced, making the movement of the counterweight smoother and more flexible, ensuring that it can quickly and accurately respond to the movement change of the bearing platform and maintain the dynamic balance of the device. At the same time, the perpendicular rotation shaft directions can effectively limit the degrees of freedom of the counterweight, prevent unnecessary rotation or deviation during movement, and further stabilize the movement trajectory of the counterweight.

[0033] As the optimization scheme of the lifting device, the lifting device further comprises a wire mounting box connected to the wall surface of the transportation space, and a cavity for accommodating the lifting device cable is arranged in the wire mounting box.

[0034] In the scheme, the cavity arranged in the wire mounting box is used to accommodate the lifting device cable, which enables the cable to be orderly received therein, avoids the cable from being tangled, pulled and other chaotic conditions during the operation of the lifting device, effectively protects the cable from damage by external factors, and ensures the stability and reliability of the electrical connection.
