Description

Technical Field

[0001] This utility model relates to the field of lifting mechanism technology, specifically a lifting mechanism. Background Technology

[0002] In scenarios such as industrial equipment maintenance, warehousing and logistics, construction, and medical assistance, lifting mechanisms are key tools for achieving "height adjustment in small spaces." Their core requirement is to achieve sufficient lifting stroke within a limited initial installation height to adapt to the height difference operation needs in confined spaces.

[0003] Based on the above, the inventors have discovered the following problems: Most existing lifting mechanisms are driven by a lead screw or synchronous belt on the lifting frame, which causes the sliding block on the lifting frame to rise and fall. The lifting height of the moving block depends on the height of the lifting frame. Therefore, when the lifting frame is high, it is difficult to use in scenarios where a large space requires a high stroke, which greatly reduces the practicality of the lifting mechanism.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a lifting mechanism in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting mechanism to solve the problem mentioned in the background art that existing lifting frames with relatively high heights are difficult to use in scenarios requiring high stroke in small spaces.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A lifting mechanism includes a main body and an auxiliary mechanism. The main body includes a base, a fixed frame is fixedly installed on the upper end of the base, a pair of slide rails are fixedly installed on both sides of the interior of the fixed frame, a lifting frame is fixedly installed between the two pairs of slide rails, a first rotating shaft is rotatably connected to one side of the interior of the lifting frame, and a first synchronous pulley is sleeved at the center of the first rotating shaft. The auxiliary mechanism includes a lifting frame, the bottom two sides of the lifting frame are respectively connected to the upper two sides of the lifting frame, slide rods are fixedly installed on both sides of the interior of the lifting frame, a movable frame is slidably installed between a pair of slide rods, a top plate is fixedly installed on the top of the lifting frame, a second rotating shaft is rotatably connected to the bottom side of the top plate, a second synchronous pulley is sleeved at the center of the second rotating shaft, and a first synchronous belt is wound between the second synchronous pulley and the first synchronous pulley.

[0007] Furthermore, a dual-shaft reducer is fixedly installed at the upper end of the base, which is located at the bottom end of the lifting frame, and a third synchronous pulley is fitted on both output shafts of the dual-shaft reducer.

[0008] The beneficial effects of adopting the above-mentioned further solution are that the dual-shaft reducer on the base can reduce the output speed of the drive motor and increase the torque, ensuring sufficient and stable power for the lifting frame to rise and fall; the third synchronous pulley on its output shaft can transmit power to the synchronous belt, realize the even distribution of power, and avoid lifting deviation caused by unilateral force.

[0009] Furthermore, a drive motor is fixedly installed on one side of the dual-shaft reducer, and the output end of the drive motor is connected to the input end of the dual-shaft reducer.

[0010] The beneficial effects of adopting the above-mentioned further solution are that the drive motor provides a power source for the entire lifting mechanism. By connecting with the dual-shaft reducer, the output speed can be controlled, thereby adjusting the lifting speed of the lifting frame to meet the lifting efficiency requirements in different scenarios. Moreover, the motor drive has a high degree of automation, reducing the burden of manual operation.

[0011] Furthermore, a third rotating shaft is rotatably connected to the top of the inner part of the fixed frame, and a pair of fourth synchronous pulleys are fitted on the third rotating shaft.

[0012] The beneficial effect of adopting the above-mentioned further solution is that a pair of fourth synchronous pulleys can ensure the consistency of synchronous belt transmission on both sides and improve the smoothness of lifting.

[0013] Furthermore, a fifth synchronous pulley is fitted at both ends of the first rotating shaft, and a second synchronous belt is wound between the fifth synchronous pulley, the fourth synchronous pulley, and the third synchronous pulley.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the fifth synchronous pulley, the fourth synchronous pulley and the third synchronous pulley form a complete transmission chain through the second synchronous belt, which can stably transmit the power of the dual-shaft reducer to the lifting frame, drive the lifting frame to rise and fall along the slide rail, and at the same time drive the first rotating shaft to rotate, so that the first synchronous pulley also rotates. The synchronous belt drive has low noise and high transmission efficiency, ensuring a smooth lifting process.

[0015] Furthermore, inside the lifting frame, a pair of fourth rotating shafts are rotatably connected to the upper end of the third synchronous pulley. Each of the fourth rotating shafts is fitted with a pair of tensioning pulleys, and both pairs of tensioning pulleys abut against the outer side of the second synchronous belt.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the tensioning wheel inside the lifting frame abuts against the outer side of the second synchronous belt, improving the tensioning effect of the second synchronous belt, preventing the second synchronous belt from slipping due to slack, and ensuring transmission efficiency.

[0017] Furthermore, one side of the first synchronous belt is fixedly connected to one end of the moving frame, and one side of the pair of second synchronous belts is fixedly connected to the inner side of the lifting frame.

[0018] The beneficial effects of adopting the above-mentioned further solution are that the first synchronous belt is fixed to the moving frame, which can drive the moving frame to slide along the slide bar to achieve local height adjustment; the second synchronous belt is fixed to the lifting frame, which can drive the lifting frame to rise and fall as a whole along the slide rail. By directly fixing the synchronous belt to the components, the transmission structure is simplified and the directness and stability of power transmission are improved.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: The main body of the lifting mechanism has a stable base that provides stable support, and the slide rail in the fixed frame guides the lifting frame to rise and fall smoothly; the slide rod of the auxiliary mechanism guides the sliding of the moving frame, and the first synchronous wheel, the second synchronous wheel and the first synchronous belt cooperate to drive the moving frame to adjust its height within the lifting frame, realizing a dual lifting function where the moving frame rises and falls simultaneously with the overall lifting frame, expanding the height adjustment range and improving the flexibility of use; the dual-shaft reducer on the base can reduce the output speed of the drive motor and increase the torque, ensuring sufficient and stable power for the lifting frame to rise and fall; the third synchronous wheel on its output shaft can transmit power to the synchronous belt, realizing the even distribution of power and avoiding lifting deviation caused by unilateral force.

The center of the second rotating shaft 203 is fitted with a second synchronous wheel 204. A first synchronous belt 115 is wound between the second synchronous wheel 204 and the first synchronous wheel 114.

[0024] As an embodiment of this utility model, a dual-shaft reducer 116 is fixedly installed at the upper end of the base 101 at the bottom end of the lifting frame 103. The two output shafts of the dual-shaft reducer 116 are each fitted with a third synchronous pulley 108. The dual-shaft reducer 116 on the base 101 can reduce the output speed of the drive motor 107 and increase the torque, ensuring sufficient and stable power for the lifting frame 103 to rise and fall. The third synchronous pulley 108 on its output shaft can transmit power to the synchronous belt, realize the even distribution of power, and avoid lifting deviation caused by unilateral force.

[0025] As an embodiment of this utility model, a drive motor 107 is fixedly installed on one side of the dual-shaft reducer 116. The output end of the drive motor 107 is connected to the input end of the dual-shaft reducer 116. The drive motor 107 provides a power source for the entire lifting mechanism. By being connected to the dual-shaft reducer 116, the output speed can be controlled, thereby adjusting the lifting speed of the lifting frame 103 to meet the lifting efficiency requirements in different scenarios. Moreover, the motor drive has a high degree of automation, reducing the burden of manual operation.

[0026] As an embodiment of this utility model, the top of the fixed frame 102 is rotatably connected to a third rotating shaft 104, and a pair of fourth synchronous pulleys 105 are sleeved on the third rotating shaft 104. The pair of fourth synchronous pulleys 105 can ensure the consistency of synchronous belt transmission on both sides and improve the stability of lifting.

[0027] As an embodiment of this utility model, the first rotating shaft 112 is further provided with a fifth synchronous pulley 113 at both ends. A second synchronous belt 111 is wound between the fifth synchronous pulley 113, the fourth synchronous pulley 105 and the third synchronous pulley 108. The fifth synchronous pulley 113, the fourth synchronous pulley 105 and the third synchronous pulley 108 form a complete transmission chain through the second synchronous belt 111, which can stably transmit the power of the dual-shaft reducer 116 to the lifting frame 103, drive the lifting frame 103 to rise and fall along the slide rail 106, and at the same time drive the first rotating shaft 112 to rotate, so that the first synchronous pulley 114 also rotates. The synchronous belt drive has low noise and high transmission efficiency, ensuring smooth lifting process.

[0028] As an embodiment of this utility model, further, a pair of fourth rotating shafts 109 are rotatably connected to the upper end of the third synchronous pulley 108 inside the lifting frame 103. Each of the fourth rotating shafts 109 is fitted with a pair of tensioning pulleys 110. Both pairs of tensioning pulleys 110 abut against the outer side of the second synchronous belt 111. The tensioning pulleys 110 inside the lifting frame 103 abut against the outer side of the second synchronous belt 111, thereby improving the tensioning effect of the second synchronous belt 111, preventing the second synchronous belt 111 from slipping due to slack, and ensuring transmission efficiency.

[0029] As an embodiment of this utility model, one side of the first synchronous belt 115 is fixedly connected to one end of the movable frame 205, and one side of a pair of second synchronous belts 111 is fixedly connected to the inner side of the lifting frame 103. The first synchronous belt 115 is fixed to the movable frame 205, which can drive the movable frame 205 to slide along the slide bar 206 to achieve local height adjustment; the second synchronous belt 111 is fixed to the lifting frame 103, which can drive the lifting frame 103 to rise and fall as a whole along the slide rail 106. By directly fixing the synchronous belts to the components, the transmission structure is simplified and the directness and stability of power transmission are improved.

[0030] Specifically, the working principle of this lifting mechanism is as follows: During use, the drive motor 107 starts and transmits power to the dual-shaft reducer 116. After reduction and torque amplification, the output shaft of the dual-shaft reducer 116 drives the third synchronous pulley 108 to rotate. The third synchronous pulley 108 drives the fourth synchronous pulley 105 on the third rotating shaft 104 at the top of the fixed frame 102 and the fifth synchronous pulleys 113 at both ends of the first rotating shaft 112 inside the lifting frame 103 to rotate synchronously via the second synchronous belt 111. The inner side of the lifting frame 103 is fixed to the second synchronous belt 111. Under the transmission action of the second synchronous belt 111, the entire structure is lifted and lowered along the slide rail 106. The tension wheel 110 inside the lifting frame 103 is always in contact with the second synchronous belt 111 to prevent the synchronous belt from slipping. When the first rotating shaft 112 rotates, it drives the first synchronous wheel 114 at the center to rotate. The first synchronous wheel 114 is driven by the first synchronous belt 115 and the second synchronous wheel 204 on the second rotating shaft 203 on the bottom side of the top plate 202. Since one side of the first synchronous belt 115 is fixed to the moving frame 205, the moving frame 205 slides along the slide bar 206 inside the lifting frame 201 under the drive of the first synchronous belt 115, thus realizing the dual adjustment of the overall lifting of the lifting frame 103 and the partial lifting of the moving frame 205.
