Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 to 8, the present embodiment provides an external lubricating device for a steel wire rope, which includes a vertically arranged funnel sealing cylinder 1 with an upper end opening and a lower end being closed, and a packing fixing cylinder 2 with an upper end being closed and a lower end opening. The upper part of the funnel sealing cylinder 1 is funnel-shaped and forms an oil storage tank 11, and the center of the bottom surface of the funnel sealing cylinder is provided with a lower through hole 12. The packing fixing cylinder 2 is inserted into the funnel sealing cylinder 1, the outer wall of the lower end of the packing fixing cylinder 2 is in threaded connection with the inner wall of the lower portion of the funnel sealing cylinder 1, and a lubricating packing 3 is sleeved between the lower end of the packing fixing cylinder 2 and the bottom surface of the funnel sealing cylinder 1. An upper through hole 21 is formed in the center of the top surface of the packing fixing barrel 2, the upper through hole 21, the lubricating packing 3 and the lower through hole 12 are coaxially arranged, and the steel wire rope 9 vertically penetrates through the upper through hole 21, the lubricating packing 3 and the lower through hole 12. A plurality of strip-shaped oil passing holes 22 are formed in the side wall of the packing fixing barrel 2 at intervals along the circumferential direction of the packing fixing barrel, the length direction of each strip-shaped oil passing hole 22 extends along the axial direction of the packing fixing barrel 2, and each strip-shaped oil passing hole 22 is communicated with the oil storage tank 11

The number of the elongated oil passing holes 22 is determined as needed, and for example, three elongated oil passing holes 22 are provided in the present embodiment. The aperture of the upper perforation 21 and the lower perforation 12 is slightly larger than the diameter of the steel wire rope 9, and the aperture of the upper perforation 21 and the lower perforation 12 is generally larger than the diameter of the steel wire rope 9 by 1 mm. The lubricating device is applied to a front-mounted oil bailing vehicle, when the lubricating device is installed, the funnel sealing cylinder 1 is connected to the middle position of two vertical upright posts 81 and is coaxially placed with a packing box 82 on a chassis of the oil bailing vehicle, and then the lower end of a steel wire rope 9 sequentially penetrates through an upper through hole 21, a lubricating packing 3, a lower through hole 12 and the packing box 82 and penetrates out of the bottom of the packing box 82. Can the axial compress tightly lubricated packing 3 through the threaded connection who adjusts packing solid fixed cylinder 2 and funnel sealed cylinder 1, packing solid fixed cylinder 2 can play spacing effect to lubricated packing 3, prevents lubricated packing 3 drunkenness round trip. Meanwhile, the axial compression degree of the packing fixing barrel 2 on the lubricating packing 3 can be adjusted by adjusting the threaded screwing degree of the packing fixing barrel and the lubricating packing, and further the radial compression degree of the lubricating packing 3 on the steel wire rope 9 is adjusted.

In detail, when the device is used, lubricating oil is firstly added into the oil storage tank 11, the amount of the added lubricating oil is generally obtained through calculation, the lubricating oil can be basically consumed after the steel wire rope 9 is placed downwards, and the lubricating oil is basically not contained in the oil storage tank 11 when the steel wire rope 9 is lifted. The whole lubricating packing 3 adopts a pressure reducing packing, namely a packing with small pressing force, has a certain axial smearing effect, and can evenly smear lubricating oil on the whole axial direction of the steel wire rope 9 by using the pressing force of the lubricating packing 3. Specifically, when the steel wire rope 9 is released, the lubricating packing 3 is adjusted to be loose, that is, the pressing force on the steel wire rope 9 is relatively small, a certain gap exists between the lubricating packing 3 and the steel wire rope 9, so that lubricating oil can enter the gap, the size of the gap determines the amount of the lubricating oil which can be taken away by the steel wire rope 9, and certainly, the lubricating packing 3 cannot be too loose, so that the lubricating oil is prevented from leaking out of the lower through hole 12 due to too large gap between the lubricating packing 3 and the steel wire rope 9; sealed packing in the packing box 82 can also be adjusted to looser, can make things convenient for wire rope 9 to pass through, avoids lubricating oil on the lubricated wire rope 9 to be scraped, influences lubricated effect.

In the process of lowering the wire rope 9, although the part of the wire rope 9 passing through the oil storage tank 11 can be soaked in the lubricating oil, the lubricating oil smeared at the moment is not uniform. When the steel wire rope 9 passes through the lubricating packing 3, lubricating oil enters a gap between the steel wire rope 9 and the lubricating packing 3 after passing through the strip-shaped oil passing hole 22, and the outer wall of the steel wire rope 9 is in a spiral shape because the steel wire rope 9 is made by coiling four strands of steel wires and a gap exists between two adjacent strands of steel wires, so that the lubricating packing 3 rotates when the lubricating packing 3 is loose; lubricating oil can be evenly smeared on the circumference of the steel wire rope 9 in the rotating process of the lubricating packing 3. Moreover, the pressing degree of the lubricating packing 3 on the steel wire rope 9 is adjusted during installation, the smearing distance of the lubricating packing 3 for smearing lubricating oil on the steel wire rope 9 can be adjusted, if the pressing force is large, the smearing distance is relatively short, and if the pressing force is small, the smearing distance is long, and the pressing force is adjusted to be proper according to actual conditions so as to ensure that the smearing distance is long and lubricating oil leakage cannot be caused.

When the steel wire rope 9 is lifted upwards, the sealing packing in the packing box 82 is adjusted to be tight, and because the oil bailing swab realizes oil bailing, the bailed oil has high pressure and the lifting speed of the steel wire rope 9 is high, the sealing packing is required to bear the pressure of about 2MPa, and crude oil is prevented from leaking from the sealing packing, so that the pressing force of the sealing packing on the steel wire rope 9 is high, and a good sealing effect is achieved; foretell lubricated packing 3 will transfer to more pine when transferring wire rope 9 relatively to it is great to lubricated packing 3 wearing and tearing when avoiding lifting wire rope 9, prolongs lubricated packing 3's life.

In the process of lifting the steel wire rope 9, because the steel wire rope 9 is uniformly coated with lubricating oil when being lowered, the lubricating oil does not need to be coated on the steel wire rope 9 when the steel wire rope 9 is lifted upwards, and the lubricating effect can still be achieved. Therefore, lubricating oil is added into the oil storage tank 11 once before the steel wire rope 9 starts to work, so that the lubricating of the whole steel wire rope 9 in the process of downward placing and upward lifting can be guaranteed, intermittent parking is not needed for lubricating work, and the working efficiency is guaranteed. In addition, as the lubricating oil is basically consumed after the steel wire rope 9 is completely placed, the lubricating packing 3 is looser, and the problem that the lubricating oil leaks from the lower through hole 12 is avoided.

Therefore, the external lubricating device for the steel wire rope in the embodiment can adjust the compression degree of the lubricating packing 3 through the matching of the funnel sealing cylinder 1 and the packing fixing cylinder 2; through the arrangement of the lubricating packing 3, after lubricating oil is added into the oil storage tank 11, the lubricating oil can enter a gap between the steel wire rope 9 and the lubricating packing 3 in the lowering process of the steel wire rope 9, so that the continuous lubrication of the steel wire rope 9 is completed; and lubricated packing 3 can rotate along with wire rope 9 in lubricated in-process, guarantees to paint more evenly, has improved lubricated effect. The lubricating packing 3 of the ingenious utilization decompression formula of whole device realizes the even lubrication to wire rope 9, and is with low costs, and simple structure, can avoid the production of accidents such as wire rope 9 jack, and the operation is safe simple and convenient, only needs to add lubricating oil in the oil storage tank 11, can accomplish lubricated operation, and whole lubricated process is reliable in succession, and lubricated effect is better, need not the clearance simultaneously and parks, has guaranteed production efficiency. In addition, when the lubricating device is installed on the front oil bailing vehicle, the structure of the oil bailing vehicle is not changed, the lubricating device is installed safely on the vehicle, and production is not influenced.

It should be noted that the external lubricating device for a steel wire rope in this embodiment may be applied to a front-mounted oil bailing cart to lubricate the steel wire rope 9 on the oil bailing cart, may also be applied to other devices requiring lubrication of the steel wire rope, and may also be used to continuously lubricate the steel wire rope, which is simple and convenient.

Generally, for convenience of operation, as shown in fig. 1, a handle 23 is fixed to a top side wall of the packing retaining cylinder 2. Preferably at the fixed two handles 23 of top lateral wall symmetry of packing solid fixed cylinder 2, utilize handle 23 more to make things convenient for to revolve to twist the operation packing solid fixed cylinder 2, and then conveniently adjust lubricated packing 3's the degree that compresses tightly.

Further, this embodiment still provides a forward type oil bailing car, and forward type oil bailing car includes chassis and wire rope 9, is fixed with two vertical posts 81 that parallel interval set up at the front end of chassis, is fixed with packing box 82 on the chassis and be located between two vertical posts 81. The front-mounted oil bailing vehicle further comprises the steel wire rope external lubricating device and two groups of fixed slips 4, and the two groups of fixed slips 4 are symmetrically connected to the side wall of the funnel sealing cylinder 1. Two groups of fixed slips 4 are respectively clamped and fixed on two vertical upright posts 81, and the lower end of a steel wire rope 9 sequentially penetrates through the upper through hole 21, the lubricating packing 3, the lower through hole 12 and the packing box 82 and penetrates out of the bottom surface of the packing box 82.

The chassis, the steel wire rope 9, the vertical upright column 81 and the packing box 82 are structural components of the front oil bailing vehicle, the specific structures of the structural components are the prior art, and the detailed description is omitted. After the external lubricating device for the steel wire rope is arranged on the front oil bailing vehicle, the continuous lubrication of the steel wire rope 9 can be realized, and the lubricating effect is better. When the external lubricating device of installation wire rope, need not to change the structure originally of forward type oil bailing car, can be along with safe installation, do not influence production. Meanwhile, because the two vertical upright posts 81 are positioned at the front end of the chassis, the whole external lubricating device of the steel wire rope is also positioned at the front end of the chassis, and the lubricating effect of the steel wire rope 9 can be conveniently and timely observed.

Still the symmetry is equipped with two steel wire righting wheels 83 in packing box 82's top generally, and wire rope 9 penetrates in packing box 82 after passing by the clearance between two steel wire righting wheels 83, plays the effect of righting, and the structure that also exists for the oil bailing car to steel wire righting wheel 83, and concrete structure is prior art also, and no longer repeated here.

In a specific implementation, in order to ensure the stability of the whole lubricating device after being connected to the vertical column 81, each set of fixed slips 4 comprises at least two fixed slips 4 arranged at intervals up and down. The number of the fixed slips 4 can be determined as required due to the limited space between the two vertical columns 81, and for the sake of simplifying the structure, each set of fixed slips 4 generally shown in fig. 1 includes two fixed slips 4 arranged in an up-down interval.

In order to conveniently clamp and fix each fixed slip 4 on the vertical upright 81 of the oil pumping truck, as shown in fig. 1, 6 and 7, each fixed slip 4 comprises two arc-shaped clamping rings 41 which are symmetrically arranged, and both ends of each arc-shaped clamping ring 41 are locked and fixed through a slip bolt 42 and a slip nut 43.

Specifically, the arc-shaped surface of each arc-shaped snap ring 41 is matched with the shape of the outer wall surface of the vertical column 81, the two ends of each arc-shaped snap ring 41 extend outwards to form a first convex plate 411 and a second convex plate 412 which are symmetrically arranged, the plate surfaces of the first convex plate 411 and the second convex plate 412 are located on the same plane, the two first convex plates 411 on the two arc-shaped snap rings 41 in each fixed slip 4 are fixedly connected through a slip bolt 42 and a slip nut 43, and the two second convex plates 412 are fixedly connected through the slip bolt 42 and the slip nut 43.

When the fixing device is installed, the two arc-shaped clamping rings 41 of each fixed slip 4 are buckled on the side wall of the vertical upright 81, then the two first convex plates 411 and the two second convex plates 412 in each fixed slip 4 are locked and fixed through the slip bolt 42 and the slip nut 43, and the fixing of each fixed slip 4 and the vertical upright 81 can be completed, so that the fixing device is simple and convenient.

In practical application, in the process of driving the oil bailing pump in the well to move by descending or lifting the steel wire rope 9, because the well casing is formed by connecting multiple sections of casing pipes in series, the adjacent two sections of casing pipes are connected in series through the casing coupling, because the inner wall of the whole casing pipe at the casing coupling is not smooth, when the oil bailing pump passes through each casing coupling, the situation of clamping can be generated to generate a vibration load, and the vibration load is transmitted to the funnel sealing barrel 1 through the steel wire rope 9 and then transmitted to the vertical upright column 81 through the funnel sealing barrel 1, so that the working stability of the whole front-mounted oil bailing vehicle is influenced. Therefore, in order to reduce the force acting on the vertical upright 81 during the lifting of the wire rope 9 and improve the stability of the whole front oil bailing vehicle, as shown in fig. 1, a damper 5 is connected between each fixed slip 4 and the side wall of the funnel sealing cylinder 1.

The outer ends of the two hanging nails 55 extend out of the end face of the cylinder body 51 and are respectively connected with the hanging lugs 6 and the lifting lugs 7.

The cushion ring 54 is made of rubber. Thus, in the lowering process of the steel wire rope 9, the funnel sealing cylinder 1 can be subjected to vibration load and can move downwards, two hanging nails 55 in each shock absorber 5 can axially extend outwards, and at the moment, a certain shock absorption effect can be achieved by the aid of the two cushion rings 54 in each shock absorber 5. During the lifting process of the steel wire rope 9, the funnel sealing cylinder 1 is subjected to vibration load and moves upwards, so that the two hanging nails 55 in each damper 5 retract axially inwards and compress the damper springs 52, and certain damping effect can be achieved by the damper springs 52 in each damper 5. Therefore, the two-way vibration reduction effect is achieved through the effects of the vibration reduction springs 52 and the two cushion rings 54 in each vibration reducer 5, the axial thrust or the axial tension of the funnel sealing cylinder 1 during the vertical movement can be relieved, the better vibration reduction effect is achieved, and the stability of the steel wire rope 9 in the lifting process is improved.

The damper 5 may serve not only to damp vibrations but also to stabilize the funnel sealing cylinder 1 in cooperation with the fixing slips 4. Specifically, the axial position of the funnel sealing cylinder 1 can be roughly adjusted by adjusting the height of the position of each fixing slip 4 fixed on the vertical upright 81; the length of the hanging nail 55 extending out of the cylinder body 51 can be adjusted through the threaded screwing degree of the hanging nail 55 and the locking ring 53 in each shock absorber 5, and then accurate adjustment can be carried out, so that the axis of the funnel sealing cylinder 1 is ensured to be in a vertical position, the center of the funnel sealing cylinder 1 can be aligned with the steel wire rope 9, the phenomenon that the inclination of the funnel sealing cylinder 1 affects the work of the steel wire rope 9 is avoided, and the effect of effective righting is achieved.

In actual use, the position of the lifting lug 7 is higher than the position of the corresponding hanging lug 6, and the axis of the cylinder body 51 is arranged to intersect with the axis of the funnel sealing cylinder 1 by 45 degrees. It will be appreciated that the aforementioned hanging lug 6 and lifting lug 7 are also obliquely arranged. The axis of the cylinder body 51 is arranged at an angle of 45 degrees, so that the hanging lug 6 and the lifting lug 7 can be conveniently welded on corresponding parts; on the other hand, the acting force on the vertical upright 81 in the lifting process of the steel wire rope 9 can be reduced, and the steel wire rope is more stable.

Further, for convenience of processing and installation, the cylinder 51 includes a central cylinder 511 with two open ends and two nuts 512 fixed to two ends of the central cylinder 511, and the through hole is opened on the nut 512. Generally, the outer end of the nut 512 protrudes outward to form a flange 5121, the outer wall of the inner end of the nut 512 is screwed to the inner wall of the central cylinder 511, and the inner side surface of the flange 5121 abuts against the end surface of the central cylinder 511.
