Description

TECHNICAL FIELD

[0001] The utility model relates to the crane related technical field, especially a crane running wheel lubricating mechanism. BACKGROUND

[0002] The crane running wheel is an important component of the crane, which undertakes the task of moving the crane and ensures the stable operation of the crane.

[0003] The wheel shaft refers to a system composed of a wheel and a shaft. When the wheel shaft is running, the wheel and the shaft will inevitably produce friction when rotating. Even if the friction coefficient is small, it will also cause wear. Therefore, lubrication is necessary to prolong the service life of the wheel shaft.

[0004] The existing wheel shaft lubrication is difficult to lubricate the transmission part between the wheel shafts, so the staff needs to spend a lot of time when lubricating. Moreover, some wheel shaft systems are small, and lubrication is more troublesome. Therefore, many wheel shaft lubrication workers cannot effectively and quickly do the job, which reduces the service life of the whole device and is inconvenient. UTILITY MODEL CONTENTS

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a crane running wheel lubricating mechanism, comprising:

[0007] A mounting frame;

[0008] A rotating shaft, the end of the rotating shaft is rotatably connected with the inner wall of the mounting frame;

[0009] A running wheel, the running wheel is equidistantly fixedly sleeved on the outside of the rotating shaft;

[0010] A squeezing wheel, the squeezing wheel is fixedly connected with the rotating shaft;

[0011] A sponge sleeve, the sponge sleeve is symmetrically sleeved on the outside of the rotating shaft with the squeezing wheel as the center;

[0012] An oil storage mechanism, the oil storage mechanism is arranged in the inside of the mounting frame and is used for guiding lubricating oil to the sponge sleeve.

[0013] Preferably, the oil storage mechanism comprises:

[0014] An oil storage tank, the oil storage tank is fixedly connected with the bottom end of the inner wall of the mounting frame;

[0015] A squeezing plate, the squeezing plate is located between the squeezing wheel and the oil storage tank;

[0016] The extrusion rod has a groove at the top of the extrusion plate and a through hole at the bottom of the oil storage tank. One end of the extrusion rod is fixedly connected to the bottom of the inner wall of the groove, and the other end of the extrusion rod is slidably inserted into the inner cavity of the through hole.

[0017] A sealing plug, which is fixedly connected to the top of the extrusion rod, is used to seal the through hole;

[0018] An elastic component is disposed between the oil reservoir and the extrusion plate.

[0019] Preferably, the oil storage mechanism further includes:

[0020] The guide rod has inclined grooves on both sides of the extrusion plate that communicate with the groove, which are used to guide the lubricating oil to the sponge sleeve.

[0021] Preferably, the elastic component includes:

[0022] A sleeve, which is symmetrically and fixedly connected to the bottom end of the oil storage tank;

[0023] A telescopic rod, one end of which is slidably inserted into the inner cavity of the sleeve, and the other end of which is fixedly connected to the extrusion plate. The cross-section of the telescopic rod is T-shaped.

[0027] The technical effects and advantages of this utility model are as follows:

[0028] This invention utilizes a combination of a compression wheel, a sponge sleeve, and an oil storage mechanism. As the traveling wheel rotates, the compression wheel intermittently squeezes the oil storage mechanism, causing lubricating oil to drip onto the sponge sleeve surrounding the shaft. This allows the sponge sleeve to continuously absorb lubricating oil and provide sustained lubrication to the shaft during continuous wheel rotation. This avoids the time-consuming, labor-intensive, and difficult-to-fully-lubricate problems of traditional manual methods, significantly improving the efficiency and effectiveness of wheel and axle lubrication, extending the overall lifespan of the device, providing strong support for the stable operation of cranes and other equipment, and making wheel and axle lubrication more convenient and efficient.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] This utility model provides, for example Figures 1-3 The crane traveling wheel lubrication mechanism shown includes a mounting frame 1, a rotating shaft 2, traveling wheels 3, a pressing wheel 4, a sponge sleeve 5, and an oil storage mechanism 6. The end of the rotating shaft 2 is rotatably inserted and connected to the inner wall of the mounting frame 1. The traveling wheels 3 are equidistantly fixedly sleeved on the outside of the rotating shaft 2. The pressing wheel 4 is fixedly inserted and connected to the rotating shaft 2. The sponge sleeve 5 is symmetrically sleeved on the outside of the rotating shaft 2 with the pressing wheel 4 as the center. The oil storage mechanism 6 is located inside the mounting frame 1 and is used to guide lubricating oil to the sponge sleeve 5. During the continuous rotation of the traveling wheel 3, the sponge sleeve 5 continuously absorbs lubricating oil and continuously lubricates the rotating shaft 2. This avoids the problems of traditional manual lubrication, which is time-consuming, laborious, and difficult to fully lubricate, greatly improving the efficiency and effect of wheel and axle lubrication, extending the service life of the overall device, providing a strong guarantee for the stable operation of cranes and other equipment, and making wheel and axle lubrication work more convenient and efficient.

[0037] The oil storage mechanism 6 includes an oil tank 61, a pressing plate 62, a pressing rod 63, a sealing plug 64, an elastic component 65, and a guide rod 66. The oil tank 61 is fixedly connected to the bottom end of the inner wall of the mounting frame 1. The pressing plate 62 is located between the pressing wheel 4 and the oil tank 61. A groove is formed at the top of the pressing plate 62, and a through hole is formed at the bottom of the oil tank 61. One end of the pressing rod 63 is fixedly connected to the bottom end of the inner wall of the groove, and the other end of the pressing rod 63 is slidably inserted into the inner cavity of the through hole. The sealing plug 64 is fixedly connected to the top end of the pressing rod 63 to seal the through hole. The elastic component 65 is disposed between the oil tank 61 and the pressing plate 62. Both sides of the pressing plate 62 have inclined grooves communicating with the groove to guide lubricating oil to the sponge sleeve 5. When the rotating shaft 2 rotates, the oil can be squeezed through the groove. The pressure roller 4 intermittently presses the extrusion plate 62, causing the extrusion rod 63 to push the sealing plug 64 out of the through hole. At this time, the lubricating oil inside the oil tank 61 can flow through the extrusion rod 63 to the inside of the groove, and then flow through the inclined groove to the guide rod 66, and drip onto the sponge sleeve 5, thereby continuously lubricating the rotating shaft 2 and the traveling wheel 3. By utilizing the cooperation between the extrusion roller 4 and the extrusion plate 62, automatic lubricating oil supply is achieved, eliminating the need for frequent manual operation and greatly improving work efficiency. Secondly, the setting of the elastic component 65 ensures a good seal between the sealing plug 64 and the through hole, preventing the leakage of lubricating oil in the non-working state and saving resources. Furthermore, the entire device has a simple and compact structure, is easy to install, and can adapt to different models and specifications of cranes and other equipment.

[0038] Example 2

[0039] Based on Example 1, such as Figure 4 As shown, the elastic component 65 includes a sleeve 651, a telescopic rod 652, and a compression spring 653. The sleeve 651 is symmetrically and fixedly connected to the bottom end of the oil reservoir 61. One end of the telescopic rod 652 is slidably inserted into the inner cavity of the sleeve 651, and the other end of the telescopic rod 652 is fixedly connected to the extrusion plate 62. The cross-section of the telescopic rod 652 is T-shaped. The compression spring 653 is located inside the sleeve 651. One end of the compression spring 653 is fixedly connected to the top end of the inner wall of the sleeve 651, and the other end of the compression spring 653 is fixedly connected to the telescopic rod 652. The compression spring 653 is always in a compressed state, thereby providing a stable downward elastic force to the telescopic rod 652. This allows the extrusion plate 62 to drive the sealing plug 64 on the extrusion rod 63 to seal the through hole and prevent lubricating oil leakage.

[0040] The top of the mounting bracket 1 is provided with an oil inlet groove, and the top of the oil storage tank 61 is threaded with a sealing cover 7. The sealing cover 7 is located inside the oil inlet groove. The sealing cover 7 can be opened through the oil inlet groove, so that lubricating oil can be added to the inside of the oil storage tank 61. In daily maintenance, it is only necessary to check the lubricating oil level of the oil storage tank 61 regularly and add it in time to ensure the normal operation of the device.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
