Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a jacking module. Background Art

[0002] The jacking module also plays an important role in a wider range of application scenarios. For example, the jacking module can be combined to lift or lower the elevation of large objects such as steel structure modules, offshore modules, large petrochemical equipment, bridges, coal transport trestles, large machinery, hulls, gantries, and conductor racks. Due to the small size of a single jacking unit, it is particularly suitable for operations in narrow spaces and is convenient for containerized transportation of equipment.

[0003] The existing lifting modules still have the following problems in actual use:

[0004] (1) During the lifting process of the lifting plate, the horizontal distance between the intersection of the upper scissor arm and the lower scissor arm and the transmission shaft is the load torque of the motor. The greater the load torque, the higher the requirement for the motor. Therefore, the lower the position of the lifting plate, the greater the load on the motor. For the same object, this structure requires a larger motor and has a high manufacturing cost. At the same time, due to the scissor-type structure, the force direction of the lifting plate is not vertical, so during the continuous lifting process, the guide shaft will wear in the direction of the upper scissor arm, which is also easy to cause the running stability of the lifting plate and affect the service life of the structure.

[0005] (2) When lifting an object, the object is directly placed on a fixed plate. As a result, the stability of the object is poor during lifting, which can easily cause the object to collapse. The overall safety is poor in practice and the relevant use costs are also increased.

[0006] For this reason, the utility model launches a jacking module. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a lifting module, which has the advantages of simple movement and stable operation, thereby achieving an extended service life and ensuring the stability of objects during lifting, thereby solving the problems raised in the background technology.

[0008] The utility model provides the following technical solution: a lifting module, including a motor a, a fixing plate d1 is fixedly installed at the bottom of the motor a to ensure the stable operation of the motor a, the output shaft of the motor a is fixedly connected to the transmission shaft b, and the output shaft of the motor a is fixedly connected to the driving gear e1 to ensure the effective transmission of the power of the motor a.

[0009] Preferably, a socket h is fixedly installed on the upper surface of the fixed plate d1, a driving source h1 is arranged on the left side of the socket h, the output shaft of the driving source h1 is fixedly connected with a screw h5, the outer surface of the screw h5 is threadedly connected with a threaded rectangular block h2, an electric telescopic rod h3 is arranged inside the threaded rectangular block h2, one end of the electric telescopic rod h3 is fixedly installed with an abutment pad h4, and the outer surface of the abutment pad h4 is slidably connected to the inside of the threaded rectangular block h2.

[0010] Preferably, a driven gear e2 is fixedly mounted on the outer surface of the transmission shaft b, and the outer surface of the driven gear e2 is meshed with the outer surface of the driving gear e1.

[0011] Preferably, a lifting gear e3 is fixedly mounted on the outer surface of the transmission shaft b, and a lifting rod f is meshed with the outer surface of the lifting gear e3.

[0012] Preferably, a lifting plate d2 is fixedly installed at one end of the lifting rod f, and a lifting rod fixing seat g is fixedly installed at the other end of the lifting rod f to ensure the stability of the lifting rod f during the lifting process. A guide rod c is slidably installed inside the lifting plate d2 to ensure the linear motion of the lifting plate d2 during the lifting process.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the process of lifting the lifting plate, the ratio design of the driving gear and the driven gear of the jacking module plays a key role in the amplification of the motor torque and the improvement of the load capacity. By reasonably selecting the gear tooth ratio (that is, the ratio of the number of teeth of the driving gear to the number of teeth of the driven gear), the output torque of the motor can be effectively amplified, so that under the same load conditions, a smaller motor can be used to meet the lifting requirements, thereby solving the problem of how to reduce the cost of use in practice, and can achieve the effect of reducing costs by using smaller motors, and can reduce the load on the motor and avoid damage to the motor. In the process of lifting the lifting plate, the lifting rod and the lifting gear perform vertical lifting actions, so the service life is longer than the original structure, thereby solving the problem of how to improve the operating life of the overall structure, and can achieve the effect of ensuring the smooth operation of the lifting plate, which is convenient for more efficient use in practice.

[0015] 2. The jacking module, through the use of a driving source and a screw, can achieve the effect of moving the abutment pad to the relevant abutment position according to the size of the object, thereby improving the adaptability in practice. Through the use of a threaded rectangular block and an electric telescopic rod, it can abut at different heights according to the actual objects, thereby achieving a more stable effect when the object is jacked up, thereby solving the problem of how to ensure the stability of the object during jacking, and achieving the effect of ensuring the stability of the object and avoiding its collapse during jacking, thereby improving the safety in practice and reducing the relevant use costs.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 - Figure 3 The jacking module includes a motor a, a fixing plate d1 is fixedly installed at the bottom of the motor a, an output shaft of the motor a is fixedly connected to a transmission shaft b, and an output shaft of the motor a is fixedly connected to a driving gear e1.

[0023] Specifically, by using a fixing plate d1 fixedly installed on the bottom of the motor a, the motor can be stably installed. The fixing plate d1 ensures that the motor a will not shake or shift during operation, thereby ensuring the overall stability and safety of the jacking module. By using a transmission shaft b and a driving gear e1 fixedly connected to the output shaft of the motor a, efficient transmission and precise control can be achieved. The transmission shaft b transmits the rotational force of the motor to subsequent components, and the driving gear e1 cooperates with the driven gear e2 to realize force transmission and direction conversion, ensuring effective power transmission and precise control.

[0024] Among them; a socket h is fixedly installed on the upper surface of the fixed plate d1, a driving source h1 is arranged on the left side of the socket h, the output shaft of the driving source h1 is fixedly connected with a screw h5, the outer surface of the screw h5 is threadedly connected with a threaded rectangular block h2, an electric telescopic rod h3 is arranged inside the threaded rectangular block h2, one end of the electric telescopic rod h3 is fixedly installed with an abutment pad h4, and the outer surface of the abutment pad h4 is slidably connected to the inside of the threaded rectangular block h2.

[0025] Specifically, by stably abutting against the object, the stability of the object can be ensured and its collapse during jacking can be avoided, thereby improving safety in practice and reducing related use costs.

[0026] Among them, a driven gear e2 is fixedly mounted on the outer surface of the transmission shaft b, and the outer surface of the driven gear e2 is meshed with the outer surface of the driving gear e1.

[0027] Specifically, a driven gear e2 is fixedly mounted on the outer surface of the transmission shaft b, and the outer surface of the driven gear e2 is meshed with the outer surface of the driving gear e1, so that the effect of smooth transmission and reduced wear can be achieved. The meshing of the driven gear e2 and the driving gear e1 ensures the continuous transmission of power, and due to the characteristics of gear transmission, the transmission process is smooth and the noise is small, while also reducing wear and extending the service life.

[0028] Among them, a lifting gear e3 is fixedly installed on the outer surface of the transmission shaft b, and a lifting rod f is meshed with the outer surface of the lifting gear e3.

[0029] Specifically, a lifting gear e3 is fixedly installed on the outer surface of the transmission shaft b, and the outer surface of the lifting gear e3 is meshed with a lifting rod f, which can achieve the effect of converting rotational motion into linear motion. The meshing of the lifting gear e3 and the lifting rod f enables the lifting rod f to move up and down, thereby realizing the lifting function of the jacking module. This structural design makes the lifting process smooth and reliable, and the lifting speed can be adjusted as needed.

[0030] Among them, one end of the lifting rod f is fixedly installed with a lifting plate d2, the other end of the lifting rod f is fixedly installed with a lifting rod fixing seat g, and a guide rod c is slidably installed inside the lifting plate d2.

[0031] Specifically, a lifting plate d2 is fixedly installed on one end of the lifting rod f, and a lifting rod fixing seat g is fixedly installed on the other end of the lifting rod f, so that the effect of stable lifting and preventing shaking can be achieved. The lifting plate d2 is used to carry the object to be lifted, and the lifting rod fixing seat g ensures that the lifting rod f will not shake or deviate from the track during the lifting process, thereby ensuring the stability and safety of the lifting process. The use of a guide rod c that is installed by sliding inside the lifting plate d2 can achieve the effect of guiding and positioning. The guide rod c slides inside the lifting plate d2 to guide and position the lifting plate d2 to prevent it from deflecting or tilting during the lifting process, thereby ensuring the accuracy and stability of the lifting.

[0032] Working principle: when in use, when stably abutting an object, first, through the bearing effect of the receiving seat h, the output shaft of the driving source h1 can be fixedly connected to the screw h5 on the internal thread of the receiving seat h and rotated, and then when the screw h5 rotates, the outer surface thread of the screw h5 can be driven to connect the threaded rectangular block h2 to move left and right according to the volume of the object, and after the position of the threaded rectangular block h2 is moved to the relevant position, the height of the abutment pad h4 can be raised or lowered to the relevant position through the action of the electric telescopic rod h3 set inside the threaded rectangular block h2, thereby ensuring the stability of the object during jacking, and then when the stabilized object is lifted, the output shaft of the motor a can be directly fixedly connected to the driving gear e1, so that the rotation of the motor a can be directly transmitted to the driving gear e1, and the driving gear e1 is meshed with the driven gear e2. Due to the principle of gear transmission, the driven gear e2 starts to rotate with the driving gear e1 at the same angular velocity but in the opposite direction. The driven gear e2 is fixedly mounted on the transmission shaft b, so the transmission shaft b also rotates accordingly. The lifting gear e3 is meshed and connected with the lifting rod f. When the transmission shaft b rotates, the lifting gear e3 also rotates accordingly. Due to the meshing action between the gear teeth, the lifting rod f will move up and down along the tooth groove direction of the gear. When the lifting rod f moves up and down, it will drive the lifting plate d2 to perform a lifting action. During the lifting and lowering process of the lifting plate d2, the guide rod c slides inside the lifting plate d2 to ensure the stability and linear motion of the lifting plate d2 during the lifting process. The rotation of the motor a is transmitted to the lifting rod f through the driving gear e1, the driven gear e2, the transmission shaft b and the lifting gear e3, and finally drives the lifting plate d2 to perform a lifting action.
