Description

Technical Field

[0001] This utility model relates to the field of oil distribution frame technology, specifically a retractable oil distribution frame for an electrical construction hoist. Background Technology

[0002] A lifting platform, also known as a lifting work platform, is a multi-functional lifting mechanical equipment. It can be divided into fixed and mobile types, guide rail type, articulated boom type, scissor type, chain type, etc. The oil distribution frame of the lifting platform is mainly used to evenly distribute lubricating oil to various lubrication points of the lifting platform, so as to lubricate and reduce wear, thereby ensuring the normal operation of the lifting platform and extending its service life.

[0003] Traditional hydraulic distributors for construction hoists are non-retractable, a design feature that imposes significant limitations on practical operations. The distributors cannot be flexibly adjusted in length, often only covering a fixed range of lubrication points. For components located off-center, additional lubrication requires manual application, increasing operational steps and labor costs. Therefore, we propose a retractable hydraulic distributor for electrical construction hoists. Utility Model Content

[0004] The purpose of this invention is to provide a retractable oil distribution frame for an electrical construction hoist, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A retractable oil distribution frame for an electrical construction hoist includes a worktable, a rotating groove, a servo motor, a lead screw, a slider, a movable seat, a support seat, and a storage tank. The top of the worktable has a rotating groove, and a servo motor is fixedly installed inside the rotating groove. A lead screw is fixedly installed at the output end of the servo motor. One end of the lead screw is rotatably connected to the inner wall of the rotating groove. A slider is threadedly connected to the outer surface of the lead screw. A movable seat is fixedly installed at the top of the slider. A support seat is fixedly installed at the top of the movable seat. A storage tank is fixedly installed at the top of the support seat.

[0007] The storage tank has an output pipe fixedly installed at the bottom of one side, and an output nozzle is fixedly installed at one end of the output pipe.

[0008] The storage tank has a feeding port on its top, and the workbench has a chute on its top.

[0009] The sliding grooves are distributed on both sides of the rotating groove, and support blocks are slidably arranged inside the sliding grooves.

[0010] The bottom of the support block is connected to a ball bearing, which is in contact with the bottom of the groove.

[0011] The top of the support block is fixedly mounted on the bottom of the movable seat, and a push rod is fixedly mounted on the bottom of the worktable.

[0012] The bottom of the push rod is movably provided with an electric push rod, the bottom of the electric push rod is fixedly provided with a support plate, a first fixing plate is fixedly provided on one side of the support plate, and a second fixing plate is fixedly provided at the bottom of the support plate. The first fixing plate and the second fixing plate are fixedly provided at a suitable position of the elevator.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This retractable oil distribution frame for an electrical construction hoist, when the oil distribution position needs to be adjusted, the servo motor starts and drives the lead screw to rotate. Because the slider is threadedly connected to the lead screw and limited by the rotating groove, the rotational motion of the lead screw is converted into the linear motion of the slider, thereby driving the moving seat, the top support seat, and the storage tank to extend and retract synchronously. At this time, the support blocks on both sides of the rotating groove slide with the moving seat within the groove, and the ball bearings at the bottom convert sliding friction into rolling friction, which reduces motion resistance and ensures stability during movement through the symmetrically distributed support structure, allowing the output nozzle to accurately reach the target oil injection position.

[0015] 2. This retractable oil distribution frame for an electrical construction hoist features an electric push rod connected to a push rod at the top and fixed to a support plate at the bottom. When the electric push rod extends or retracts, it synchronously raises and lowers the worktable and the structure above, ensuring the output nozzle is at the same horizontal level as the component to be oiled. Simultaneously, the support plate is firmly fixed to the appropriate position on the hoist via a first and second fixing plate, providing stable support for the entire device and preventing positional shifts due to vibration during operation. Oil in the storage tank flows out naturally through the output pipe and output nozzle, completing the oil distribution operation. The entire process achieves coordinated control of extension and retraction, meeting the oil distribution needs of different construction scenarios. Attached Figure Description

[0022] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution:

[0023] A retractable oil distribution frame for an electrical construction hoist includes a worktable 1, a rotating groove 2, a servo motor 3, a lead screw 4, a slider 5, a movable seat 6, a support seat 7, and a storage tank 8. The top of the worktable 1 has a rotating groove 2. The servo motor 3 is fixedly installed inside the rotating groove 2. The output end of the servo motor 3 is fixedly installed with a lead screw 4. One end of the lead screw 4 is rotatably connected to the inner wall of the rotating groove 2. The outer surface of the lead screw 4 is threadedly connected with a slider 5. The top of the slider 5 is fixedly installed with a movable seat 6. The top of the movable seat 6 is fixedly installed with a support seat 7. The top of the support seat 7 is fixedly installed with a storage tank 8.

[0024] A rotating groove 2 is located on the top of the worktable 1, its shape matching the installation requirements of the servo motor 3 and the lead screw 4; it is a rectangular groove. The groove walls are precision-machined to ensure stability during the rotational connection of the lead screw 4 end, while providing a stable installation space for the servo motor 3 to prevent displacement during motor operation. The servo motor 3, as the power source for the extension and retraction of the oil distributor, employs a high-precision servo control system capable of precisely controlling its speed and direction. Its output torque and power are designed according to the load conditions of the oil distributor to ensure smooth operation of components such as the lead screw 4 and the slider 5. The motor housing is typically made of aluminum alloy, which has good heat dissipation performance and is suitable for the working environment of the construction hoist.

[0025] An output pipe 9 is fixedly installed on one side of the bottom of the storage tank 8, and an output nozzle 10 is fixedly installed at one end of the output pipe 9. A feeding port 11 is opened on the top of the storage tank 8. A slide groove 12 is opened on the top of the workbench 1. The slide groove 12 is distributed on both sides of the rotating groove 2. A support block 13 is slidably installed inside the slide groove 12. A ball bearing 14 is slidably connected to the bottom of the support block 13. The ball bearing 14 is in contact with the bottom of the slide groove 12. The top of the support block 13 is fixedly installed on the bottom of the movable seat 6. A push rod 15 is fixedly installed on the bottom of the workbench 1. An electric push rod 16 is movably installed on the bottom of the push rod 15. A support plate 17 is fixedly installed on the bottom of the electric push rod 16. A first fixed plate 18 is fixedly installed on one side of the support plate 17. A second fixed plate 19 is fixedly installed on the bottom of the support plate 17. The first fixed plate 18 and the second fixed plate 19 are fixedly installed at appropriate positions of the elevator.

[0026] Storage tank 8 is generally made of stainless steel, which has good corrosion resistance and prevents oil from corroding the tank body. The capacity of the tank is designed according to the oil consumption requirements of the construction hoist. A feeding port 11 is opened at the top for easy oil filling, and an output pipe 9 is connected to the bottom of one side to ensure smooth oil flow. The push rod 15 is fixed to the bottom of the worktable 1 and is made of steel pipe with high strength. Its length is determined according to the installation and height adjustment requirements of the electric push rod 16. The top is fixedly connected to the worktable 1, and the bottom is movably connected to the electric push rod 16, transmitting the extension and retraction movement of the electric push rod 16 to the worktable 1.

[0027] In this embodiment, a retractable oil distribution frame for an electrical construction hoist operates as follows: First, when the oil distribution position needs adjustment, the servo motor 3 starts and drives the lead screw 4 to rotate. Since the slider 5 is threadedly connected to the lead screw 4 and limited by the rotating groove 2, the rotational motion of the lead screw 4 is converted into the linear motion of the slider 5, which in turn drives the moving seat 6, the top support seat 7, and the storage tank 8 to extend and retract synchronously. At this time, the support blocks 13 on both sides of the rotating groove 2 slide with the moving seat 6 within the sliding groove 12. The ball bearings 14 at the bottom convert sliding friction into rolling friction, reducing motion resistance and ensuring stability during movement through the symmetrically distributed support structure, allowing the output nozzle 10 to accurately reach the target oil injection position. Then, the top of the electric push rod 16 is connected to the push rod 15, and the bottom is fixed to the support plate 17. When the electric push rod 16 extends or retracts, it drives the worktable 1 and the upper structure to rise and fall synchronously, ensuring that the output nozzle 10 and the part to be oiled are at the same horizontal level. Meanwhile, the support plate 17 is firmly fixed to the appropriate position of the elevator by the first fixing plate 18 and the second fixing plate 19, providing stable support for the entire device and preventing position displacement due to vibration during operation. The oil in the storage tank 8 flows out naturally through the output pipe 9 and the output nozzle 10, completing the oil distribution operation. The entire process realizes coordinated control of extension and lifting, meeting the oil distribution needs under different construction scenarios.
