Description

Technical Field

[0001] The invention relates to the technical field of hydroelectric generator assembly, and more specifically to an electric lifting vehicle for generator assembly and maintenance. Background Art

[0002] Electric lift trucks can provide convenience when installing, maintaining and repairing generator sets in hydropower plants, especially when it is necessary to lift personnel or tools to a higher position for work; electric lift trucks usually have a stable lifting platform, easy-to-operate control system and sufficient carrying capacity, which makes them an ideal choice for performing aerial work.

[0003] Currently, when using cross-lifting, the carrier is located at a high altitude, wherein the items or tools inside the carrier are unevenly placed, resulting in unequal forces on both sides of the carrier, causing the carrier to tilt and easily collapse. In view of this, we propose an electric lift for generator assembly and maintenance. Summary of the invention

[0004] The purpose of the present invention is to provide an electric lifting vehicle for generator assembly and maintenance to solve the technical problem that items or tools inside a load frame are unevenly placed, resulting in unequal forces on both sides of the load frame, causing the load frame to tilt and easily cause collapse.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an electric lifting vehicle for generator assembly and maintenance, comprising a base with a plurality of rollers, a lifting mechanism being arranged on the top of the base;

[0006] The lifting mechanism comprises two first brackets, a stabilizing unit and a supporting unit, and the stabilizing unit is fixedly connected to the lifting mechanism;

[0007] The first bracket is symmetrically structured and fixedly connected to the top of the base, a load-bearing frame is provided on the top of the base, and a second bracket is symmetrically structured and fixedly connected to the bottom of the load-bearing frame, a lifting module is provided on the side of the base opposite to the load-bearing frame, a ladder is fixedly connected to one side of the load-bearing frame, and an auxiliary rod is fixedly connected to one side of the load-bearing frame. The present invention can tow the load-bearing frame by winding up the rope, and can improve the stability of the load-bearing frame at high altitudes to prevent the load-bearing frame from shaking. At the same time, the load-bearing frame is supported by a metal plate, and a triangular support function is formed by a branch plate to improve the stability of the load-bearing frame during high-altitude operations. The present invention makes the load-bearing frame more stable during high-altitude operations by using ropes and metal plates, and avoids uneven force in the load-bearing frame during high-altitude operations, which causes the load-bearing frame to tilt and affects personal safety, and is conducive to improving the stability and reliability of the device.

[0008] Preferably, the lifting module is composed of a plurality of transmission rods and support rods, wherein one of the transmission rods is movably sleeved between two first brackets, and another transmission rod is movably sleeved between two second brackets.

[0009] Preferably, the stabilizing unit includes a first motor, the first motor is fixedly connected to the bottom of the support frame, the output end of the first motor is fixedly connected to a transmission cylinder, the outer wall of the transmission cylinder is movably sleeved with a rope, and the side surface of one of the transmission rods is fixedly sleeved with a fixing frame and one end of the rope is fixedly sleeved on the side surface of the fixing frame. By fixing the first motor to the bottom of the support frame, it is ensured that the operation of the motor provides stable support for the support frame, reducing the risk of tilting due to changes in the center of gravity during the lifting process. The design of the transmission cylinder enables the rope to evenly distribute force, so that the force borne by the support frame during lifting is more uniform, reducing the risk of excessive force on one side, thereby preventing potential structural instability.

[0010] Preferably, the inner walls on both sides of the transmission cylinder are fixedly connected with a plurality of buffer strips, and the buffer strips are distributed in a circular array. The present invention provides a rope, and when the rope is wound, a traction force can be applied to the bearing frame to improve the stability of the bearing frame. At the same time, in the process of winding the rope, the tension generated by the rope winding can be buffered by the buffer strip, which is conducive to improving the service life of the device. By providing the rope, when the rope is wound, an effective traction force is provided to the bearing frame, thereby significantly improving the stability of the bearing frame. This design ensures that the bearing frame can resist external environmental factors such as wind or unbalanced load during high-altitude operations, reducing the risk of tilting. In addition, in the process of winding the rope, the application of the buffer strip can effectively absorb and alleviate the tension fluctuations caused by the rope winding, avoiding damage to the equipment caused by the sharp force change. This tension buffer mechanism not only improves the stability of the operation, but also significantly reduces the wear of the rope and other components, thereby extending the service life of the entire device, reducing maintenance costs and improving the safety and reliability of the operation. This innovative design can effectively improve the operating efficiency in practical applications and ensure that the equipment always maintains the best performance during multiple lifting processes.

[0011] Preferably, the support unit design includes two plug rods, which are movably sleeved at the two ends of one of the transmission rods to form a flexible support structure. This design allows the plug rods to be freely extended and retracted as needed, thereby adjusting the height and stability of the support frame to adapt to different working environments and needs. At the same time, the two ends of the other transmission rod are also movably sleeved with telescopic sleeves. This mechanism allows the plug rod to move freely inside the telescopic sleeve to achieve more precise support adjustment.

[0012] Through this structure, the support unit can effectively disperse the load of the carrier and improve its overall stability. When working at height, the flexible adjustment of the plug rod can quickly respond to unexpected mechanical changes, ensuring that the carrier always remains in a safe and horizontal state. In addition, this design can also simplify the operation process, reduce the skill requirements for the operator, and make operations in complex environments more efficient.

[0013] Preferably, two ends of the other transmission rod are movably sleeved with metal plates.

[0014] Preferably, the symmetrical structures on the side surface of the other transmission rod are respectively fixedly connected with a plurality of ratchets, and the ratchets are distributed in a ring array, and the inner wall of the metal plate is movably connected with a pawl through the first support rod, and the pawl is meshingly connected with the ratchets.

[0015] Preferably, a branch plate is fixedly connected to one side of the metal plate. This design forms a triangular support structure when the load frame is working at high altitude, which significantly enhances the stability of the load frame. The combination of the firmness of the metal plate and the support of the branch plate enables the load frame to effectively disperse and resist external forces or wind forces when affected by these forces, thereby reducing the risk of tilting or collapse.

[0016] This triangular support structure has superior mechanical stability, allowing the carrier to maintain balance in various uneven or dynamic environments. In addition, the metal plate design provides a rigid support surface that not only resists lateral pressure, but also effectively improves the durability of the entire device and reduces deformation or damage caused by long-term use.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention can pull the load-bearing frame by winding up the rope, which can improve the stability of the load-bearing frame in the air to prevent the load-bearing frame from shaking. At the same time, the load-bearing frame is supported by the metal plate, and the branch plate forms a triangular support function to improve the stability of the load-bearing frame during high-altitude operations. The present invention uses ropes and metal plates to make the load-bearing frame more stable during high-altitude operations, avoids uneven force inside the load-bearing frame during high-altitude operations, and causes the load-bearing frame to tilt, affecting personal safety, which is beneficial to improving the stability and reliability of the device.

[0019] 2. The present invention provides a rope, which can provide traction to the load-bearing frame when the rope is wound up, thereby improving the stability of the load-bearing frame. At the same time, during the process of winding up the rope, the tension generated by the winding up of the rope can be buffered by the buffer strip, which is beneficial to increasing the service life of the device.

[0020] 3. The present invention significantly improves the stability of the load-bearing frame by arranging a metal plate to form a triangular support when the load-bearing frame is working at high altitude. The triangular support structure has inherent mechanical advantages. It can effectively disperse and carry external forces from all directions, and reduce the risk of tilting due to center of gravity shift or environmental factors (such as wind, vibration, etc.). This stability is crucial for high-altitude operations, because the working environment is often uncertain and dangerous, and ensuring the balance of the load-bearing frame can directly affect the safety of the operators. In addition, the firmness and rigidity of the metal plate enable the load-bearing frame to maintain its shape when it is loaded, preventing the performance of the equipment from being affected by material fatigue or deformation. This design not only enhances the durability of the overall structure, but also reduces the frequency of maintenance and replacement of components, thereby reducing operating costs.

DETAILED DESCRIPTION

[0027] like Figures 1 to 5 As shown, the present invention relates to an electric lifting vehicle for generator assembly and maintenance, comprising a base 1 with a plurality of rollers, and a lifting mechanism 2 is arranged on the top of the base 1;

[0028] The lifting mechanism 2 includes two first brackets 201, a stabilizing unit 3 and a supporting unit 4, and the stabilizing unit 3 is fixedly connected to the lifting mechanism 2;

[0029] The first bracket 201 is symmetrically structured and fixedly connected to the top of the base 1. A load-bearing frame 202 is arranged on the top of the base 1. The bottom of the load-bearing frame 202 is symmetrically structured and fixedly connected to the second bracket 203. A lifting module 204 is arranged on the side opposite to the base 1 and the load-bearing frame 202. It is worth noting that the lifting module 204 adopts a cross-type lifting and uses a scissor-shaped mechanical structure to realize the vertical lifting of goods. A ladder 205 is fixedly connected to one side of the load-bearing frame 202. An auxiliary rod 206 is fixedly connected to one side of the load-bearing frame 202. The present invention can pull the load-bearing frame 202 by winding the rope 303, which can improve the stability of the load-bearing frame 202 in the air to prevent the load-bearing frame 202 from shaking. At the same time, the metal plate 403 supports the carrier frame 202, and forms a triangular support function through the branch plate 403a, thereby improving the stability of the carrier frame 202 during high-altitude operations. The present invention uses ropes 303 and metal plates 403 to make the carrier frame 202 more stable during high-altitude operations, thereby avoiding uneven force inside the carrier frame 202 during high-altitude operations, causing the carrier frame 202 to tilt and affect personal safety, and is beneficial to improving the stability and reliability of the device. When in use, the staff enters the interior of the carrier frame 202 through the ladder 205, and then uses the external control mechanism to enable the lifting module 204 to work, driving the carrier frame 202 to move upward, wherein items and tools can be placed through the auxiliary rod 206.

[0030] In an embodiment of the present invention, the lifting module 204 is composed of a plurality of transmission rods 204a and support rods 204b, wherein one transmission rod 204a is movably connected between the two first brackets 201, and the other transmission rod 204a is movably connected between the two second brackets 203. It is worth noting that during the lifting process, the two transmission rods 204a move inside the first bracket 201 and the second bracket 203 respectively, and this method has a good lifting function.

[0031] In an embodiment of the present invention, the stabilization unit 3 includes a first motor 301, which is fixedly connected to the bottom of the support frame 202, and the output end of the first motor 301 is fixedly connected to a transmission cylinder 302, and the outer wall of the transmission cylinder 302 is movably sleeved with a rope 303, wherein a side surface of one of the transmission rods 204a is fixedly sleeved with a fixing frame 304 and one end of the rope 303 is fixedly sleeved on the side surface of the fixing frame 304. By setting the rope 303, the present invention can apply traction to the support frame 202 when winding the rope 303, thereby improving the stability of the support frame 202. At the same time, in the process of winding the rope 303, the tension generated by the winding of the rope 303 can be buffered by the buffer strip 302a, which is beneficial to improving the service life of the device.

[0032] In an embodiment of the present invention, a plurality of buffer strips 302a are fixedly connected to the inner walls on both sides of the transmission cylinder 302, and the buffer strips 302a are distributed in a circular array. It is worth noting that the buffer strips 302a are made of metal and have a certain elastic deformation function. At the same time, during the winding of the rope 303, the buffer strips 302a are bent, so that the tension of the rope 303 during winding can be buffered, so as to avoid excessive tension on the rope 303, which may cause wear of the rope 303. At high altitude, the first motor 301 is first operated through an external circuit mechanism, and the first motor 301 drives the transmission cylinder 302 to rotate, so that the rope 303 is wound, and the rope 303 is tightened to pull the support frame 202, which can stabilize the support frame 202 and prevent the support frame 202 from tilting. The tension generated by the winding of the rope 303 can be buffered through the buffer strips 302a.

[0033] As another embodiment of the present invention, the support unit 4 includes two plug rods 401, which are movably sleeved at two ends of one of the transmission rods 204a, and the two ends of the other transmission rod 204a are movably sleeved with telescopic sleeves 402, and the plug rods 401 are movably sleeved inside the telescopic sleeve 402. The two ends of the other transmission rod 204a are movably sleeved with metal plates 403, and the symmetrical structures on the side surfaces of the other transmission rod 204a are fixedly connected with a plurality of ratchet teeth 404, and the ratchet teeth 404 are distributed in a ring array. The inner wall of the metal plate 403 is movably connected with a pawl 405 through the first support rod, and the pawl 405 is meshed with the ratchet teeth 404. Next, the present invention sets a metal plate 403. When the carrier frame 202 is working at high altitude, a triangular support is formed by the metal plate 403, which can improve the stability of the carrier frame 202 and is beneficial to improving the stability of the device. At the same time, during the lifting and lowering process of the carrier frame 202, the insertion rod 401 and the telescopic sleeve 402 are extended, and the metal plate 403 is fixed to the bottom of the carrier frame 202, wherein the carrier frame 202 is supported by the branch plate 403a and the metal plate 403 to form a triangular support, which can improve stability. During this process, the ratchet 404 is engaged with the pawl 405 to prevent it from moving and always contact with the bottom of the carrier frame 202.

[0034] As another embodiment of the present invention, a branch plate 403a is fixedly connected to one side of the metal plate 403. It is worth noting that the metal plate 403 and the branch plate 403a are fixed to the bottom of the support frame 202, wherein a triangle is formed by the branch plate 403a to make it more stable. During use, one side of the support frame 202 can be supported to make it more stable during use.

[0035] Working principle: This embodiment provides an electric lift for generator assembly and maintenance. When in use, the staff enters the interior of the carrier frame 202 through the ladder 205, and then uses the external control mechanism to make the lifting module 204 work, driving the carrier frame 202 to move upward, wherein the auxiliary rod 206 can be used to place objects and tools. In the air, the first motor 301 is firstly operated through the external circuit mechanism, and the first motor 301 drives the transmission cylinder 302 to rotate, so that the rope 303 is wound up, and the rope 303 is tightened to pull the carrier frame 202, which can be used to lift the carrier frame 202. 2 performs a stabilizing function, thereby preventing the carrier 202 from tilting, wherein the buffer strip 302a can buffer the tension generated by the winding of the rope 303, and at the same time, during the lifting and lowering process of the carrier 202, the insertion rod 401 and the telescopic sleeve 402 are extended, and the metal plate 403 is fixed to the bottom of the carrier 202, wherein the carrier 202 is supported by the branch plate 403a and the metal plate 403 to form a triangular support, which can improve stability. In this process, the ratchet 404 is engaged with the pawl 405 to prevent it from moving and always contacting with the bottom of the carrier 202.
