Description

Novel long-life welding puller

Technical Field

The utility model relates to a technical field of excavator spare part for engineering construction specifically is a novel longevous horse pull head of welding.

Background

The horsehead is a fixing device for connecting the tail end of a small arm and a bucket on an excavator, the I-shaped frame is also called a swing frame for the similar product, the horsehead belongs to an important component in an excavator working device, and the horsehead needs to be stably and accurately positioned on the excavator working device, so that the horsehead needs to have strong toughness, wear resistance, corrosion resistance and other performances, the existing excavator is severe in working conditions, the horsehead is exposed in the air for a long time and collides with water, mud, stones and the like, the horsehead is short in service time and extremely large in abrasion loss, and the problems that parts are abraded and short in service life due to long-term small-area contact of a shaft and a sleeve.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The utility model provides a to prior art not enough, the utility model provides a reduce the maintenance number of times and practice thrift use cost, the novel longevous horse pull head of welding of increase of service life 3 to 4 times.

(II) technical scheme

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel longevous horse pull head of welding, includes horse pull head body and axle sleeve, the horse pull head body is cylindrical outer real hollow structure, and the axle sleeve sets up in horse pull head body inside and in the middle of adding there is lubricating grease, and the horse pull head body both ends are provided with the oil blanket, and the oil blanket is located the axle sleeve outside, still includes the lubrication oil duct, the lubrication oil duct sets up at horse pull head body middle part, establishes planetary reciprocal lubrication oil duct in the axle sleeve, horse pull head body top middle part is provided with the connecting pipe, and the connecting pipe communicates with each other with the lubrication oil.

Preferably, the connecting pipe is fixedly connected with the horsehead body through a pipe joint.

Preferably, the input port of the connecting pipe is a grease filling port.

(III) advantageous effects

Compared with the prior art, the utility model provides a novel longevous horse pull head of welding possesses following beneficial effect: through having increased the lubricated area of lubricated oil duct, increased original part lubrication area and use area of contact, after the area of contact increases, axle and cover are by about one time increase of original area, and the lubricating grease use amount is still less, and the lubricating grease oil film retention time is longer, and axle and cover life increase by times, and equipment operation personnel have alleviateed intensity of labour, and the owner has saved the maintenance frequency and has practiced thrift use cost, has prolonged life.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a horsehead body; 2. a shaft sleeve; 3. oil sealing; 4. a lubricating oil passage; 5. a connecting pipe; 6. a pipe joint; 7. and a lubricating grease filling port.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It will be understood by those skilled in the art that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for convenience and simplicity of description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus are not to be considered limiting.

Referring to fig. 1, a welded novel long-life horse head comprises a horse head body 1 and a shaft sleeve 2, the horse head body 1 is a cylindrical hollow structure with an outer solid, the shaft sleeve 2 is arranged in the horse head body 1, lubricating grease is added in the middle of the horse head body 1, oil seals 3 are arranged at two ends of the horse head body 1, the oil seals 3 are arranged at the outer side of the shaft sleeve 2, the lubricating grease channel 4 is arranged in the middle of the horse head body 1, the shaft sleeve 2 is arranged in the lubricating grease channel 4, the original contact area is enlarged by increasing the lubricating grease channel 4, after the contact area is increased, the original area of the shaft and the sleeve is increased by about one time, the using amount of the lubricating grease is less, the oil film holding time of the lubricating grease is longer, the service lives of the shaft and the sleeve are increased by times, a connecting pipe 5 is arranged in the middle of the top end of the horse head body 1, the connecting pipe 5 is communicated with the lubricating, an input port of the connecting pipe 5 is a lubricating grease filling port 7, and lubricating grease can be input into the connecting pipe 5 and the horse head body 1 through the lubricating grease filling port 7.

When the puller is used, a shaft needs to be arranged on the shaft sleeve 2 in the puller, various tensile force and pressure generated by material digging of equipment and the like act on the shaft of the puller and the shaft sleeve 2, and the shaft rotates in the shaft sleeve 2 by about 180 degrees heavily during working, so that lubricating grease needs to be filled in the shaft and the shaft sleeve 2, the service life of the puller is determined by the material, hardness, contact area and lubricating oil use of the shaft and the shaft sleeve 2, therefore, the original use contact and lubricating area is increased by adding the lubricating oil channel 4 and the shaft sleeve 2, after the contact area is increased, the original area of the shaft and the sleeve is increased by about one time, the using amount of the lubricating grease is less, the oil film holding time of the lubricating grease is longer, the service lives of the shaft and the sleeve are increased by times, the labor intensity of workers is reduced, the maintenance times of equipment owners are saved, the use cost is saved.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.
