Description

Technical Field

[0001] This utility model relates to the field of material lifting platform technology, specifically a lifting platform with precise positioning. Background Technology

[0002] A lifting platform is a type of mechanical equipment used to transport goods from a lower level to a higher level. It is particularly important in industrial processes involving the processing and transportation of sheet metal, where lifting platforms are frequently used to move materials from lower to higher or vice versa, transporting them to different heights in storage areas for stacking or palletizing. However, currently used lifting platforms often lack precise positioning structures. Due to factors such as transmission inertia, they are prone to shifting at positions where they should stop, making precise control and adjustment difficult. These errors affect operations requiring precise material transport.

[0003] Based on this, the present invention designs a precisely positioned lifting platform to solve the above problems. Summary of the Invention

[0006] The transmission mechanism includes a servo motor, a synchronous belt driven by the servo motor, and a bracket connecting plate fixedly connected to the outer wall of the synchronous belt;

[0007] The positioning mechanism includes rubber anti-collision blocks fixed to the upper and lower ends of the lifting column, a pull rope sensor and a proximity sensor respectively set at the upper and lower ends of the lifting column, and the monitoring rope end of the pull rope sensor is fixed to the bottom of the bracket connecting plate.

[0008] The stabilizing mechanism includes two mounting plates fixed to the outer wall of the bracket connecting plate, two main bearing wheels rotatably connected to the outer wall of the mounting plates, two symmetrical mounting seats fixed to the outer wall of the mounting plates, and a secondary bearing wheel rotatably connected between the two mounting seats.

[0009] Preferably, a protective cover is fixed to the outer wall of the lifting column, and an active synchronizing wheel is rotatably connected to the inner wall of the protective cover. A planetary reducer is connected between the active synchronizing wheel and the drive shaft of the servo motor.

[0010] Preferably, the outer wall of the lifting column is rotatably connected to an auxiliary synchronous pulley and two driven synchronous pulleys, and the synchronous belt drive is connected between the driving synchronous pulley, the auxiliary synchronous pulley, and the two driven synchronous pulleys.

[0011] Preferably, a bracket is fixed to the bottom end of the lifting column, and the rope sensor is fixed to the outer wall of the bracket.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] Firstly, the movement range of the support connecting plate of the equipment material is limited and determined by the upper and lower rubber anti-collision blocks and the proximity sensor to prevent it from exceeding the limit position and affecting the operation. The displacement position and distance of the support connecting plate are monitored in real time through the pull rope sensor, which makes it easier to control and adjust it to make its stopping position more accurate.

[0016] Secondly, the main and auxiliary rollers work together to move along the straight rails on both sides of the lifting column, further stabilizing the movement of the support connecting plate and making the up-and-down movement of the support connecting plate more stable and precise, and less prone to deviation.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a precisely positioned lifting platform, comprising: a lifting column 1, a transmission mechanism, a stabilizing mechanism, and a positioning mechanism;

[0028] The transmission mechanism includes a servo motor 11, a synchronous belt 3 driven by the servo motor 11, and a bracket connecting plate 4 fixedly connected to the outer wall of the synchronous belt 3.

[0029] The positioning mechanism includes rubber anti-collision blocks 8 fixed at the upper and lower ends of the lifting column 1, a pull rope sensor 10 and a proximity sensor 17 respectively set at the upper and lower ends of the lifting column 1, and the external rope end of the pull rope sensor 10 is fixed to the bottom of the bracket connecting plate 4.

[0030] The stabilizing mechanism includes two mounting plates 13 fixed to the outer wall of the bracket connecting plate 4, two main bearing wheels 14 rotatably connected to the outer wall of the mounting plates 13, two symmetrical mounting seats 15 fixed to the outer wall of the mounting plates 13, and a secondary bearing wheel 16 rotatably connected between the two mounting seats 15.

[0031] In the transmission mechanism, a servo motor 11 is used as the power source for the synchronous belt 3 to control the synchronous belt 3 to move the auxiliary support connecting plate 4 for lifting operations. In the positioning mechanism, two rubber anti-collision blocks 8 are respectively set at the upper and lower limit positions of the support connecting plate 4 to control its movement range. The proximity sensors 17 located at the upper and lower ends are used for precise monitoring. After the range is determined, the rope sensor 10 is used to monitor its movement distance in real time to ensure relatively accurate positioning requirements. In the stabilization mechanism, the auxiliary rollers 16 of the two mounting seats 15 of the mounting plate 13 are set facing each other, and work with the main roller 14 to further stabilize the movement of the support connecting plate 4.

[0032] A further preferred embodiment has a protective cover 5 fixed to the outer wall of the lifting column 1, an active synchronous wheel 6 rotatably connected to the inner wall of the protective cover 5, and a planetary reducer 12 drivingly connected between the active synchronous wheel 6 and the drive shaft of the servo motor 11.

[0033] The main transmission parts of the synchronous belt 3 are protected by the protective cover 5, and the planetary reducer 12 enables the servo motor 11 to provide relatively stable power output to the active synchronous pulley 6.

[0034] In a further preferred embodiment, the outer wall of the lifting column 1 is rotatably connected to the auxiliary synchronous wheel 7 and the two driven synchronous wheels 2, and the synchronous belt 3 is connected between the driving synchronous wheel 6, the auxiliary synchronous wheel 7 and the two driven synchronous wheels 2.

[0035] Two driven synchronous pulleys 2 are used to stretch the synchronous belt 3 to the upper and lower ends of the lifting column 1, while the auxiliary synchronous pulley 7 is used to tighten the synchronous belt 3 to cooperate with the driving synchronous pulley 6 for transmission.

[0036] A further preferred embodiment has a support 9 fixed to the bottom of the lifting column 1, and a rope sensor 10 fixed to the outer wall of the support 9;

[0037] The lifting column 1 is equipped with a rope sensor 10 installed on the bracket 9, which monitors the puller connection plate in a suitable position.

[0038] Preferably, the rubber head ends of both rubber anti-collision blocks 8 are positioned facing the bracket connecting plate 4;

[0039] The rubber anti-collision block 8 uses a relatively soft rubber head to absorb the impact of the buffer support connecting plate 4.

[0040] In a further preferred embodiment, the outer wall of the lifting column 1 is provided with two track plates, which respectively contact the main contact wheel 14 and the auxiliary contact wheel 16 of the two mounting plates 13;

[0041] The main mounting wheel 14 and the auxiliary mounting wheel 16 of the mounting plate 13 are distributed at a 90-degree angle to each other and are attached to the track plate of the lifting column 1 to control the stable up and down movement of the support.

[0042] A specific application of this embodiment is as follows: the outer wall of the support connecting plate 4 is provided with a variety of connection holes for connecting with the material support to load the material. During the lifting operation, the servo motor 11 rotates towards the active synchronous wheel 6. The servo motor 11 maintains a stable output torque by slowing down through the planetary reducer 12. With the cooperation of the active synchronous wheel 6, the auxiliary synchronous wheel 7 and the driven synchronous wheel 2, the synchronous belt 3 can rotate on the lifting column 1, which in turn drives the support connecting plate 4 loaded with goods to move on one side of the lifting column 1. When the support connecting plate 4 moves up and down, the main contact wheel 14 and the auxiliary contact wheel 16 of the two mounting plates 13 respectively contact the straight rail plates on both sides of the lifting column 1 to move, making the support connecting plate 4 more stable and accurate when moving up and down, and less prone to deviation.

[0043] The movement range of the support connecting plate 4 is limited and defined by the upper and lower rubber anti-collision blocks 8. With the monitoring of two proximity sensors 17, it is prevented from exceeding the limit position and affecting the operation. At the same time as the support connecting plate 4 moves, the monitoring rope of the pull rope sensor 10 is pulled at the same time, and the length of the pull rope also changes accordingly. By measuring the change in the length of the pull rope, the displacement distance of the support connecting plate 4 can be monitored in real time, which facilitates control and adjustment to make its stopping position more accurate.
