Description

Technical Field

[0001] The utility model relates to the technical field of guide wheels of electric single-beam cranes, and more specifically, to a guide wheel device of an electric single-beam crane. Background Art

[0002] In the existing technology, the guide wheel device of the electric single-beam crane is one of the key components of the crane operation. However, there are some problems with this device during use. First, the existing guide wheel device of the electric single-beam crane usually adopts gear meshing transmission. This transmission method ensures the stability and reliability of the crane operation to a certain extent. However, due to the characteristics of gear meshing transmission, the existing equipment is often not convenient for lubrication. Insufficient lubrication will lead to increased wear between gears, thereby affecting the normal use effect and service life of the equipment. In addition, insufficient lubrication may also cause increased noise during equipment operation, affecting the comfort of the working environment.

[0003] Furthermore, due to the lack of lubrication in the existing electric single-beam crane guide wheel device, it limits the application ability of the equipment in the crane. In actual operation, the guide wheel device needs to be lubricated regularly to ensure smooth operation between gears. If the lubrication process is complicated and cumbersome, the operator needs to spend more time and energy to complete the process, which not only reduces production efficiency, but also may increase the difficulty of operation and the possibility of errors. In addition, insufficient lubrication may also affect the operating performance and stability of the crane, because increased gear wear may lead to reduced transmission efficiency, which in turn affects the crane's lifting capacity and operating speed.

[0009] The utility model is further configured such that a compression spring is sleeved on the intermediate tube, one end of the compression spring is connected to the one-way plate, and the other end of the compression spring is connected to the threaded tube. The action of the compression spring enables the one-way plate to maintain a stable pressure during the adjustment process, thereby ensuring the sealing effect between the one-way plate and the sealing sleeve, and at the same time allowing the one-way plate to be flexibly opened and closed during lubrication, thereby enhancing the reliability of the lubrication system.

[0010] The utility model is further configured such that the adjusting tube is threadedly connected in the middle tube, and a top spring is provided on the adjusting tube, and the top spring abuts against the middle tube. The setting of the top spring provides additional support and pressure, thereby ensuring the stability of the middle tube during the adjustment process, preventing adjustment errors caused by vibration, and improving the accuracy and durability of the adjustment mechanism.

[0011] The utility model is further configured such that an external tube is provided on the side wall of the oil outlet pipe, one end of the external tube is connected to the oil outlet pipe, and the other end of the external tube is connected to an external oil supply device. This configuration enables the lubricating oil to be directly transported from the external oil supply device to the oil outlet pipe, and then the flow rate is controlled by an adjusting mechanism, thereby realizing continuous oil supply to the lubrication system and improving lubrication efficiency.

[0013] The utility model is further configured such that a rotating shaft is provided on the movable frame, and the roller is rotatably connected to the rotating shaft.

This structure enables the power of the external driving device to be effectively transmitted to the driving wheel, thereby driving the operation of the entire movable frame and the crane, thereby improving the operating efficiency of the crane and the reliability of power transmission.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a guide wheel device for an electric single-beam crane, which has the following beneficial effects:

[0017] 1. The design of the connection mechanism enables the lubrication mechanism to work closely with the driving wheel, mobile frame and other components. Through the cooperation of the oil outlet pipe, sealing sleeve and other parts, the smooth flow and effective sealing of the lubricating oil are ensured. This design not only simplifies the lubrication process and reduces maintenance time, but also enhances the flexibility and reliability of the equipment.

[0018] 2. The clamping mechanism realizes a close connection between the driving wheel and the lubrication mechanism through the cooperation of the one-way plate, sealing sleeve and other parts. When the driving wheel rotates, the seal between the one-way plate and the sealing sleeve is released, and the lubricating oil can flow out, thereby realizing the lubrication of the driving wheel. This mechanism ensures that the driving wheel can be continuously lubricated during the operation of the crane, thereby improving the safety and stability of the equipment operation.

[0019] 3. The mobile mechanism includes rollers, driven wheels and other parts, and its design makes the crane move more stable and smooth. The meshing of the rollers with the single beam and the meshing of the driven wheels with the driving wheels enables the power of the driving equipment to be effectively transmitted to the mobile mechanism of the crane. This structure not only improves the operating efficiency of the crane, but also ensures the stability and reliability of the crane. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In this embodiment, when the crane needs to be used, the driving wheel 2 is first driven to rotate through the driving device, and then the driven wheel 15 is engaged with the driving wheel 2, which drives the roller 14 to rotate, thereby driving the crane to move, and then the lifting process is carried out. When the driving wheel 2 is rotating, it will hit the resistance plate 4, and then drive the resistance plate 4 to move upward. Since the adjusting tube 7 is threadedly connected to the intermediate tube 10, it will drive the one-way plate 8 to release the seal between the sealing sleeve 9. At this time, the lubricating oil in the oil outlet pipe 3 will flow out and then flow into the driving wheel 2, thereby completing the lubrication process.

[0031] More specifically, when it is necessary to adjust the oil output each time, it is only necessary to change the position of the bottom plate and the one-way plate 8 so that the moving position of the one-way plate 8 driven by the driving wheel 2 can be changed each time. Since the adjusting thread is connected in the middle tube 10, the position between the resistance plate 4 and the one-way plate 8 can be changed, thereby changing the opening between the one-way plate 8 and the sealing sleeve 9 each time, thereby changing the oil output each time, and thus completing the adjustment process.

[0032] In summary, when the overall equipment is in use or running: when the crane needs to be used, the driving wheel 2 is first driven to rotate through the driving device, and then because the driven wheel 15 is engaged with the driving wheel 2, it will drive the roller 14 to rotate, thereby driving the crane to move, and then the lifting process is performed. When the driving wheel 2 is rotating, it will hit the contact plate 4, and then drive the contact plate 4 to move upward. Since the adjusting tube 7 is threadedly connected to the intermediate tube 10, it will drive the one-way plate 8 to release the seal between the sealing sleeve 9. At this time, the lubricating oil in the oil outlet pipe 3 will flow out and then flow into the driving wheel 2, thereby completing the lubrication process. When it is necessary to adjust the oil output each time, it is only necessary to change the position of the bottom plate and the one-way plate 8. Therefore, the moving position of the one-way plate 8 driven by the driving wheel 2 can be changed each time. Since the adjusting thread is connected in the intermediate tube 10, the position between the contact plate 4 and the one-way plate 8 can be changed, thereby changing the opening between the one-way plate 8 and the sealing sleeve 9 each time, thereby changing the oil output each time, and then completing the adjustment process.
