Description

Technical Field

[0001] This invention belongs to the field of motor base technology, specifically relating to an automatic leveling motor base suitable for low-temperature environments. Background Technology

[0002] The motor base is a crucial component of the motor, supporting its operation and ensuring stable performance. The flatness of the motor base directly impacts the motor's lifespan and performance. The motor is mounted on the ground or a mounting platform via the base. Base leveling typically employs either manual or automatic leveling systems. Manual leveling is cumbersome, inaccurate, and rarely used anymore. Traditional automatic leveling systems require a motor and high-precision sensors, resulting in high maintenance costs, a complex leveling process, and significant time consumption. Furthermore, even after a period of use, the level of the motor may change, leading to increased vibration and irreversible damage at the base-to-ground connection, rendering traditional automatic leveling systems ineffective. Additionally, in extremely cold regions or low-temperature environments such as cold chain logistics warehouses, electronic components in the control structure of automatic leveling systems are prone to failure, affecting normal operation. Moreover, in low-temperature environments, the motor consumes more energy during initial startup, and even with specialized antifreeze lubricants, insufficient lubrication may still occur in the initial stages. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic leveling motor base suitable for low-temperature environments, which solves the problems of high maintenance costs, cumbersome leveling process, inability to level when irreversible damage occurs at the connection between the base and the ground in traditional automatic leveling systems, easy failure of electronic components in low-temperature environments, large power consumption during initial motor start-up, and insufficient lubrication.

[0008] Preferably, the leveling frame is fixedly connected to the outer wall of the fixed cylinder by an L-shaped reinforcing rod, and two infrared receivers are fixedly installed on the side wall of the leveling frame.

[0009] Preferably, a spring is installed inside the fixed cylinder, and a T-shaped slide rod is slidably connected inside the fixed cylinder. An arc-shaped groove is provided at the top of the T-shaped slide rod. A hemispherical block is fixedly connected to the bottom of the support frame. The bottom of the hemispherical block is fitted with the top of the T-shaped slide rod. Two second electric telescopic rods are fixedly installed at the top of the fixed cylinder. The output ends of the two second electric telescopic rods are fixedly connected to an annular plate. Two inserts are fixedly installed at the top of the annular plate. An insert rod is provided directly above each insert. The top of each insert rod is fixedly connected to the bottom of the support frame.

[0010] Preferably, a hydraulic cylinder is fixedly installed inside the leveling cylinder, and a lifting frame is fixedly installed at the output end of the hydraulic cylinder. The bottom end of the lifting frame extends out of the leveling cylinder and is slidably connected to it. A threaded rod is fixedly installed at the bottom end of the lifting frame, and a damping and shock-absorbing pad is fixed between the bottom end of the lifting frame and the threaded rod.

[0011] Preferably, the protective frame has a U-shaped cross-section when viewed from above. Two sealing frames are fixedly installed around the inner side of the outer wall of the protective frame, and the two sealing frames are arranged parallel to each other vertically. The sealing frames have a U-shaped cross-section when viewed from above. A sealing plate is slidably connected around the inner side of the protective frame. The sealing plate has a U-shaped cross-section when viewed from above. The vertical width of the sealing plate is less than the distance between the two sealing frames. When the sealing plate slides up and down, it abuts against the upper and lower sealing frames respectively. A limiting block is fixed on the side of the sealing plate closest to the sealing frame.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0013] (1) By using the heating cavity, hose, and air hole combined with T-shaped tie rod and obstruction frame, the hot air entering the heating cavity through the hose is heated through the air hole above, preheating the motor, increasing the temperature, preventing insufficient lubrication due to low temperature, reducing the initial power consumption of the motor, and preventing the electronic components of the control system from malfunctioning.

[0014] (2) By setting a fixed cylinder for positioning and limiting, it is convenient to install the support frame and motor frame. At the same time, after the motor has been working for a long time, irreversible damage occurs at the connection between the bolt and the ground. Two second electric telescopic rods and insert rods are inserted into the insert cylinder to temporarily provide stable working conditions for the motor, prevent the motor from vibrating violently, and ensure that the staff has time to stop the machine and avoid irreversible damage to the motor due to vibration.

[0015] (3) By sliding the conductive rod against the side wall of the resistor block and combining it with the battery box, the conductive rod can move slightly under the vibration of the motor, so that the current after it comes into contact with the resistor block changes continuously. When the change exceeds the threshold, the automatic leveling structure is activated to realize the automatic adjustment of the motor, ensuring the stable operation of the motor. No motor or high-precision sensor is required, reducing costs. The leveling process is simple and improves efficiency.

[0016] Of course, implementing any of the technical solutions of this invention does not necessarily require achieving all of the above effects simultaneously. Attached Figure Description

[0027] The technical solution of the present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figures 1-4As shown, an automatic leveling motor base suitable for low-temperature environments includes a fixed cylinder 4, a support frame 1 fixedly connected to the top of the fixed cylinder 4, a first electric telescopic rod 2-4 fixedly installed at the center of the top of the support frame 1, a lifting frame 2-7 fixedly installed at the output end of the first electric telescopic rod 2-4, the top surface of the lifting frame 2-7 being flush with the bottom surface of the motor frame 2, positioning cylinders 2-6 fixedly installed on both sides of the top of the support frame 1 at the first electric telescopic rod 2-4, the top of the positioning cylinders 2-6 being inclined inside, and two positioning rods 2-5 fixedly connected to the bottom of the motor frame 2, the bottom end of each positioning rod 2-5 extending into the corresponding... The positioning cylinder 2-6 is slidably connected to it. The motor frame 2 is provided with mounting slots 2-10. Leveling cylinders 3 are fixedly installed at the four corners of the bottom of the support frame 1. Dovetail grooves 2-2 are symmetrically arranged along the front and rear directions on the top front and rear center of the motor frame 2. Dovetail blocks 2-3 are slidably connected in each dovetail groove 2-2. A movable frame 2-1 is fixedly connected to the top of each dovetail block 2-3. A protective frame 1-10 is fixedly sleeved on the outside of the support frame 1. Limiting frames 1-1 are symmetrically fixedly installed on the front and rear inner walls of the protective frame 1-10. Each movable frame 2-1 is located directly below the corresponding limiting frame 1-1. 1. Adjusting screws 1-5 are bolted to the side wall. One end of each adjusting screw 1-5 is rotatably connected to a trapezoidal push block 1-6. A sliding plate 1-8 is installed below each movable frame 2-1. A slot 1-9 is provided on each sliding plate 1-8. Each trapezoidal push block 1-6 is inserted into its corresponding slot 1-9 and slidably connected thereto. A guide rod 1-7 is inserted into each sliding plate 1-8 and slidably connected thereto. The top end of each guide rod 1-7 is fixedly connected to the bottom end of its corresponding limiting frame 1-1. The bottom end of each guide rod 1-7 is fixedly connected to the top end of the support frame 1. The movement is achieved through a fixed cylinder. Positioning ensures precise installation; the movable frame slides to both sides to fully engage with the bottom of the limiting frame, ensuring its horizontality and facilitating the overall installation of the motor frame. The first electric telescopic rod further secures the movable frame to the limiting frame, providing double protection for its horizontal placement. Adjusting the screw causes the inclined surface of the trapezoidal push block to abut against the top surface of the slot, causing the sliding plate to move upward and clamp the movable frame, improving device stability. After the sliding plate clamps the frame, the first electric telescopic rod retracts and does not participate in shock absorption, extending its service life. Simultaneously, the positioning cylinder is used for positioning and limiting to prevent misalignment of the motor frame during installation.

[0029] like Figures 1-2As shown, the leveling frame 1-3 is fixedly connected to the outer wall of the fixed cylinder 4 by an L-shaped reinforcing rod 1-18. Two infrared receivers 1-4 are fixedly installed on the side wall of the leveling frame 1-3. An infrared transmitter 1-2 is fixedly installed at the top of each limit frame 1-1. The infrared transmitter 1-2 and the infrared receiver 1-4 are respectively set facing each other. The limit frame is ensured to be longitudinally level by transmitting light signals through the infrared transmitter and the infrared receiver. A spirit level is placed on the leveling frame, and the reading is observed to determine its lateral level, thus completing the initial adjustment, simplifying the level adjustment process and improving work efficiency to a certain extent.

[0030] like Figure 3 , Figure 5 , Figure 6 As shown, a heating cavity 1-11 is provided inside the side wall of the protective frame 1-10. The top view cross-section of the protective frame 1-10 is U-shaped. Two sealing frames 1-12 are fixedly installed around the inner side wall of the protective frame 1-10. The two sealing frames 1-12 are arranged parallel to each other vertically. The top view cross-section of the sealing frames 1-12 is U-shaped. A sealing plate 1-13 is slidably connected around the inner side wall of the protective frame 1-10. The top view cross-section of the sealing plate 1-13 is U-shaped. The vertical width of the sealing plate 1-13 is less than [missing information]. The distance between the two sealing frames 1-12 is such that when the sealing plate 1-13 slides up and down, it abuts against the upper and lower sealing frames 1-12 respectively. A limiting block 1-19 is fixed on the side of the sealing plate 1-13 closest to the sealing frame 1-12. The limiting block 1-19 is located between the upper and lower sealing frames 1-12. T-shaped tie rods 1-15 are symmetrically rotated and connected to the bottom end of the sealing plate 1-13. The bottom end of each T-shaped tie rod 1-15 extends beyond the protective frame 1-10 and is slidably connected to it. The bottom ends of the protective frame 1-10 are... A symmetrically fixed obstruction frame 1-16 is installed. The obstruction frame 1-16 is horizontally placed in a T-shape. The T-shaped tie rod 1-15 and the obstruction frame 1-16 are respectively set and engaged. A set of air holes 1-17 are evenly arranged on the upper and lower sides of the inner wall of the protective frame 1-10. Each set of air holes 1-17 has multiple through holes. The support frame 1 is located between the upper and lower sets of air holes 1-17. A flexible hose 1-14 is fixedly connected to one side of the outer wall of the protective frame 1-10. The flexible hose 1-14 communicates with the heating cavity 1-11. 14. Connect to the output end of the external hot air box. The external hot air box is equipped with heating resistance wires and a fan that generates airflow. By rotating the T-shaped pull rod to disengage from the obstruction frame, and pulling the T-shaped pull rod downwards, the sealing plate blocks the sealing frame, so that all the hot air entering the heating cavity through the hose is heated through the air hole above, preheating the motor, raising the temperature at the bearing, reducing energy consumption, avoiding the problem of severe wear caused by insufficient lubrication, and preventing the electronic components in the automatic control structure from malfunctioning due to low temperature.

[0031] like Figure 2 , Figure 9As shown, conductive rods 3-10 are fixedly connected to the side walls of each leveling cylinder 3, and resistor blocks 3-11 are fixedly installed on the side walls of each connecting plate 4-6. One end of each conductive rod 3-10 is slidably connected to the side wall of the corresponding resistor block 3-11. A hydraulic cylinder 3-1 is fixedly installed inside the leveling cylinder 3. A lifting frame 3-2 is fixedly installed at the output end of the hydraulic cylinder 3-1. The bottom end of the lifting frame 3-2 extends out of the leveling cylinder 3 and is slidably connected to it. A threaded rod 3-3 is fixedly installed at the bottom end of the lifting frame 3-2. A damping and shock-absorbing pad 3-4 is fixed between the bottom end of the lifting frame 3-2 and the threaded rod 3-3. A threaded sleeve 3-5 is connected to the external thread of the threaded rod 3-3. A rotating rod 3-6 is fixedly connected to the bottom end of the threaded sleeve 3-5. A base 3-7 is rotatably connected to the bottom end of the rotating rod 3-6. Multiple threads are connected to the base 3-7. Bolts are used to fix the top of the base 3-7 with the telescopic plate 3-8. The top of the telescopic plate 3-8 is slidably connected to the telescopic cylinder 3-9. The top of each telescopic cylinder 3-9 is fixedly connected to the bottom of the corresponding lifting frame 3-2. Each telescopic cylinder 3-9 has a threaded locking pin on its outer wall. After the motor has been working for a period of time, vibration may cause the bolts to loosen slightly or the connection with the ground to deform or break slightly, resulting in increased vibration amplitude at one corner of the motor. This causes changes in the normal current fluctuation after the conductive rod and the resistor block are connected, triggering the corresponding hydraulic cylinder to work and achieve automatic adjustment to maintain level. If the vibration amplitude exceeds the threshold during motor operation, the hydraulic cylinder in the corresponding leveling cylinder extends, causing the whole structure to move downward, ensuring a tight distance between the support frame and the ground, achieving automatic adjustment and reducing the vibration amplitude.

[0032] like Figure 2 , Figure 3 , Figure 7 , Figure 8As shown, battery boxes 4-8 are symmetrically fixedly installed on the outer bottom of the side wall of the fixed cylinder 4. Each conductive rod 3-10 is connected to one end of the battery in the battery box 4-8 through a wire, and the other end of the battery in the battery box 4-8 is connected to the corresponding resistor block 3-11 through a wire. Locking bolts are installed on each battery box 4-8. The fixed cylinder 4 is fixedly connected to the ground through locking bolts. Connecting plates 4-6 are symmetrically fixedly installed on the outer top of the side wall of the fixed cylinder 4. Signal transmitters 4-7 are fixedly installed on the top of each connecting plate 4-6. The signal transmitters 4-7 are connected to the power cabinet and the batteries in the battery boxes 4-8. The power cabinet is connected to the control system of the central control center. A spring 4-1 is installed inside the fixed cylinder 4. A T-shaped slide rod 4-2 is slidably connected inside the fixed cylinder 4. An arc groove is provided at the top of the T-shaped slide rod 4-2. A hemispherical block 2-8 is fixedly connected to the bottom of the support frame 1. The bottom of the hemispherical block 2-8 is connected to the top of the T-shaped slide rod 4-2. The mounting system features two second electric telescopic rods 4-3 fixedly installed at the top of the fixed cylinder 4. The output ends of the two second electric telescopic rods 4-3 are jointly fixedly connected to the annular plate 4-4. Two insert cylinders 4-5 are fixedly installed at the top of the annular plate 4-4. An insert rod 2-9 is installed directly above each insert cylinder 4-5, and the top of each insert rod 2-9 is fixedly connected to the bottom of the support frame 1. The mounting system, with its arc-shaped groove and hemispherical block fitting together, facilitates the positioning and installation of the support frame and the fixed cylinder. In emergency situations where irreversible damage occurs at the connection between the base and the ground after prolonged operation, and the automatic leveling structure cannot be adjusted, the two second electric telescopic rods extend the insert rods into the insert cylinders. The fixed cylinder then participates in the shock absorption and leveling work, using the fixed cylinder for limiting and fixing. This provides a stable working environment for the motor in a short time. At the same time, the signal transmitter triggers an alarm to urge the operator to handle the situation, minimizing the risk of irreversible damage to the motor.

[0033] Working principle: First, the fixing cylinder 4 is installed in the center of the installation area. The fixing cylinder 4 is used for positioning. The fitting of the arc-shaped groove and the hemispherical block 2-8 facilitates the positioning of the support frame 1 and the fixing cylinder 4. The support frame 1 is then installed, and the motor frame 2 is placed on and fixed to it. The motor is then installed. The mounting slots 2-10 allow bolts or other fasteners to pass through and mate with the corresponding holes on the motor frame. The motor is precisely positioned and firmly fixed in the required position, ensuring the stability of the motor during operation and preventing displacement due to vibration or external force. Then, initial leveling is performed. The light signals from the two infrared transmitters 1-2 and the infrared receiver 1-4 are used to ensure longitudinal horizontality. The leveling frame... Place a spirit level on 1-3 and observe the reading to determine its horizontal level. Rotate the threaded sleeve 3-5 at the corresponding position. After adjustment, rotate the locking bolt on the corresponding telescopic cylinder 3-9 for secondary tightening to ensure stable support, simplify the leveling process, and keep the motor in a stable working state. During the leveling process, after the motor is fixed to the motor frame 2 with bolts, the motor and the motor frame 2 are a whole. The first electric telescopic rod 2-4 extends first, and the two moving frames 2-1 move to both sides so that the top of the moving frame 2-1 is tightly attached to the bottom of the limit frame 1-1. The level of the limit frame 1-1 is used to ensure the level of the moving frame 2-1, which facilitates the overall installation of the motor frame 2.

[0034] After the motor frame 2 is placed, as the two movable frames 2-1 move to both sides, the two adjusting screws 1-5 are rotated to move the trapezoidal push block 1-6. The inclined surface of the trapezoidal push block 1-6 abuts against the inner top surface of the slot 1-9, causing the sliding plate 1-8 to move upward and clamp the movable frame 2-1 to ensure its stable operation. After the sliding plate 1-8 is clamped, the first electric telescopic rod 2-4 retracts and does not participate in the shock absorption work, effectively extending the service life of the first electric telescopic rod 2-4. At the same time, the positioning cylinder 2-6 is set to position and limit the motor frame 2 during the initial installation process to prevent the motor frame 2 from being misaligned.

[0035] After initial leveling, to ensure smooth operation of the equipment in low-temperature environments, first rotate the T-shaped tie rod 1-15 so that its bottom is disengaged from the obstruction frame 1-16. Simultaneously, pull down the symmetrically arranged T-shaped tie rod 1-15, limiting the position of the limit block 1-19, causing the sealing plate 1-13 to seal the lower sealing frame 1-12. This allows the hot air entering the heating cavity 1-11 through the hose 1-14 to be heated through a set of air holes 1-17 above the support frame 1, preheating the motor and raising the temperature at the bearings. This effectively reduces the impact of low temperatures (the output shaft, after shutdown maintenance, has lost its temperature due to prolonged operation, requiring initial startup). When in motion, it is prone to making a clicking sound, indicating significant wear. After starting, simultaneously pull the T-shaped lever 1-15 upwards to block the sealing plate 1-13 from the upper sealing frame 1-12. Rotate the T-shaped lever 1-15, and the bottom of the symmetrically arranged T-shaped lever 1-15 engages with the corresponding obstruction frame 1-16. The obstruction frame 1-16 supports 1-15 to prevent it from falling. As the motor starts, the motor itself generates heat during operation, so no auxiliary heating is needed. Hot air is discharged through a set of air holes 1-17 below the support frame 1, maintaining the temperature of the monitoring structure and other parts below, keeping them at a suitable temperature for lubricating oil operation, and without affecting the transmission of electrical signals.

[0036] After a period of operation, vibration may cause the bolts to loosen slightly or the connection with the ground to deform or break slightly, leading to increased vibration in one corner. This causes changes in the normal current fluctuation after the conductive rod 3-10 and resistor block 3-11 are connected. The signal transmitter 4-7 sends a signal to the power cabinet, which, in conjunction with the control system, triggers the corresponding hydraulic cylinder 3-1 to adjust, achieving automatic adjustment and maintaining horizontality. The specific circuit connection principle is as follows: the conductive rods 3-10 are all connected to one end of the battery in the battery box 4-8 through wires, and the other end of the battery in the battery box 4-8 is connected to... The corresponding resistor block 3-11 is connected by a wire, and the signal transmitter 4-7 is connected to the power cabinet and the battery box 4-8. During normal operation, the motor vibration causes the conductive rod 3-10 to move slightly on the resistor block 3-11, causing the current to change continuously. Within the normal range, the motor can work stably. When the vibration amplitude exceeds the threshold, the signal transmitter 4-7 sends a signal to cause the hydraulic cylinder 3-1 in the corresponding leveling cylinder 3 to extend, causing the whole to move down, ensuring that the distance between the support frame 1 and the ground is compact, realizing automatic adjustment and reducing the vibration amplitude.

[0037] When irreversible damage occurs at the connection between the base 3-7 and the ground after prolonged operation, and the automatic leveling structure is no longer able to adjust (e.g., severe ground damage, severely damaged bolt threads preventing locking, or significant lateral vibration of the motor), in an emergency, the signal transmitter 4-7 sends a signal to the power cabinet. The power cabinet, in conjunction with the control system, extends the two second electric telescopic rods 4-3 upwards, allowing the insertion rod 2-9 to enter the insertion cylinder 4-5. This initiates the vibration damping and leveling operation of the fixed cylinder 4. The fixed cylinder 4 (normally, it does not participate in vibration damping, thus maintaining a relatively intact connection with the ground) is used for limiting and fixing, providing a stable working environment for the motor for a short period to prevent severe motor vibration. Simultaneously, the signal transmitter 4-7 triggers an alarm. After observing and determining a solution, the operator stops the machine to minimize irreversible damage to the motor (e.g., breakage of the output shaft under significant ground vibration, or burnout due to excessive motor load).
