[0002] Crane transport vehicles, also known as truck-mounted cranes, are special vehicles that integrate lifting and transportation functions. They achieve cargo lifting, rotation, and hoisting functions by installing a hydraulic lifting system on a truck chassis. The crane boom is the core operating component of the crane transport vehicle, directly undertaking the functions of cargo lifting, hoisting, and rotation. Its structure and performance directly determine the vehicle's lifting capacity and operating range.

[0003] Currently, cranes are frequently used at busy construction sites or logistics centers. The bearings inside the crane boom base suffer from wear and overheating due to excessive friction, requiring workers to frequently climb up to the crane boom to add lubricating oil. This not only increases the workload but also increases safety risks.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] As shown in Figure 1, a crane boom base for a crane transport vehicle according to one embodiment of the present invention includes a fixing component 1, a support component 2 rotatably connected inside the fixing component 1, a bearing installed between the fixing component 1 and the support component 2, the crane boom being mounted on the top end face of the support component 2, and self-lubricating components 3 being installed on both sides of the top end face of the fixing component 1 on the support component 2, the inner sidewall of the self-lubricating component 3 being in contact with the support component 2, the rotation of the support component 2 driving the rotation of the crane boom, and simultaneously driving the self-lubricating component 3 to work, so that the lubricating oil in the self-lubricating component 3 is transferred to the top of the support component 2, and then flows downward to the bearing, thereby achieving lubrication of the bearing.

[0029] As shown in Figures 3-5, the self-lubricating component 3 includes an oil storage section, a release section, a fixing section, and a pre-storage section. The oil storage section includes a lubrication cavity 301, which has a hollow structure. Several sets of mounting grooves 3011 are formed on the inner wall of the lubrication cavity 301 near the support component 2. Each set of mounting grooves 3011 has a pair of rotating holes 3012 on its inner wall. An internal thread 3013 is formed on the top end face of the lubrication cavity 301. The release section includes a rotating ball 302. The outer wall of the rotating ball 302 fits against the inner wall of the mounting groove 3011. The upper and lower end faces of the rotating ball 302 are integrally formed with fixing posts 3021 that match the rotating holes 3012. The outer wall of the rotating ball 302 fits against and slides against the mounting groove 3011. On the inner wall of the mounting groove 3011, the outer wall of the fixing column 3021 rotates on the inner wall of the rotating hole 3012. In use, lubricating oil is introduced into the lubrication cavity 301. The height of the bottom inner wall of the lubrication cavity 301 gradually decreases from the side away from the rotating ball 302 to the side of the rotating ball 302, so that the lubricating oil flows in the lubrication cavity 301 towards the side closer to the rotating ball 302. When the support assembly 2 rotates, it drives the outer wall of the rotating ball 302 to rotate on the inner wall of the mounting groove 3011. The lubricating oil inside the lubrication cavity 301 adheres to the outer wall of the rotating ball 302. Through the rotation of the rotating ball 302, the lubricating oil reaches the outside of the lubrication cavity 301 and adheres to the surface of the support assembly 2.

[0030] The fixing part includes a pair of fixing blocks 303, which are located on both sides of the lubrication cavity 301. Threaded holes 3031 are provided on the outer walls of the pair of fixing blocks 303. The fixing assembly 1 includes a fixing ring 101. Two pairs of mounting holes 1012 that match the self-lubricating assembly 3 are provided on the top end face of the fixing ring 101. During installation, the self-lubricating assembly 3 is fixed above the fixing assembly 1 by screws threadedly connecting to the threaded holes 3031 and the mounting holes 1012.

[0031] As shown in Figure 6, the pre-storage unit includes an oil bottle 304. An external thread 3041, matching the internal thread 3013, is provided on the bottom end face of the oil bottle 304. A rotating rod 3042 is fixedly connected to the inner wall of the external thread 3041 on the oil bottle 304. A baffle plate 3043 is fixedly connected to the outer wall of the rotating rod 3042. When lubricating oil needs to be added, the lubrication chamber 301 does not need to be disassembled. Rotating the oil bottle 304 causes the external thread 3041 to mesh with the internal thread 3013, causing the external thread 3041 to move away from the internal thread 3013. Then, lubricating oil is filled into the oil bottle 304. During installation, it is quickly flipped and tightened. The baffle plate 3043 prevents the lubricating oil in the oil bottle 304 from flowing downwards, thus preventing the lubricating oil from overflowing during installation. The pre-storage unit reduces the number of times lubricating oil needs to be added.

[0032] As shown in Figures 2 and 5, a clearance groove 1011 is provided on the top outer wall of the fixed ring 101 that fits against the outer ring 202 of the bearing. The clearance groove 1011 provides a flow path for the lubricating oil, making it easier for the lubricating oil to flow onto the bearing. The inner ring 102 of the bearing is fixedly connected to the inner wall of the fixed ring 101. The support assembly 2 includes a support base 201, and the outer ring 202 of the bearing is fixedly connected to the outer wall of the support base 201. A guide block 2011 is fixedly connected to the outer wall of the support base 201 above the outer ring 202 of the bearing. The outer wall of the rotating ball 302 fits against the outer wall of the guide block 2011. The guide block 2011 is located directly above the bearing. When the rotating arm drives the guide block 2011 to rotate, it drives the rotating ball 302 to rotate, thereby transferring the lubricating oil inside the lubrication cavity 301 to the surface of the guide block 2011, and then flowing down along the guide block 2011 onto the bearing, thus achieving lubrication of the bearing.

[0033] During use, the power component inside the rotating arm (not shown in the figure) drives the rotating arm to rotate, realizing the meshing rotation of the bearing inside the base. At the same time, through the guide block 2011 on the base and the self-lubricating component 3, the rotating arm transfers the lubricating oil in the self-lubricating component 3 to the top of the guide block 2011 while rotating. The bearing is located below the guide block 2011. The lubricating oil located above the guide block 2011 flows down along the guide block 2011 to the inside of the bearing, thus lubricating the bearing. This eliminates the need for frequent addition of lubricating oil by the operator, greatly reducing the burden on the operator.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
