Abstract
The utility model relates to a kind of all-hydraulic drill fairlead, comprise holder, gland and be fixed on a pair slips between holder, gland, a pair slips superposition is in circular, the outboard end of slips is equipped with protruding cascade ring, the upper surface of holder and the soffit of gland are all in the semicircle being convenient to radial location a pair slips, be bolted between holder and gland, the junction of holder and gland is provided with the gap of 2 ~ 3mm.The beneficial effects of the utility model are: without any seal and bearing, and processing is simple, and required precision is relatively low, and the job site more serious at dust is also not easily affected; If the convenient fairlead damage in drilling process of field maintenance, only needs the attachment bolt unclamping base and gland, just can change fairlead slips or integral replacing fairlead.
Description
Technical field
The utility model relates to a kind of all-hydraulic drill fairlead.
Background technology
Fairlead is the vitals of all-hydraulic drill.In drilling process, when there is high vibration or displacement because the hole that collapses, armful brill etc. are unexpected in rig. drilling rod can produce larger swing.At this moment fairlead is just needed to lead to it, the distortion avoiding it excessive and cause fracture. and also protective effect is served to the rubber sleeve chuck of unit head.But while carrying out leading. fairlead is very easily subject to the eccentric force of drilling rod applying and damages.The fairlead that current all-hydraulic drill uses mainly adopts rolling bearing to add the structure of movable drum, is not easy to keep in repair after damage.Therefore, the fairlead designing a kind of new construction is necessary.Make field maintenance more convenient.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of all-hydraulic drill fairlead.
The utility model solves the technical scheme that its technical problem adopts: a kind of all-hydraulic drill fairlead, comprise holder, gland and be fixed on a pair slips between holder, gland, a pair slips superposition is in circular, the outboard end of slips is equipped with protruding cascade ring, the upper surface of holder and the soffit of gland are all in the semicircle being convenient to radial location a pair slips, be bolted between holder and gland, the junction of holder and gland is provided with the gap of 2 ~ 3mm.
Further, the material of slips is copper alloy.
The beneficial effects of the utility model are: without any seal and bearing, and processing is simple, and required precision is relatively low, and the job site more serious at dust is also not easily affected; If the convenient fairlead damage in drilling process of field maintenance, only needs the attachment bolt unclamping base and gland, just can change fairlead slips or integral replacing fairlead.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation one of the present utility model;
Fig. 2 is structural representation two of the present utility model.
Wherein: 1. slips, 2. holder, 3. gland, 4. bolt.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of all-hydraulic drill fairlead as shown in Figure 1, 2, a pair slips 1 comprising holder 2, gland 3 and be fixed between holder 2, gland 3, a pair slips 1 superposes in circular, the outboard end of slips 1 is equipped with protruding cascade ring, dependence cascade ring positions, the upper surface of holder 2 and the soffit of gland 3 are all in the semicircle being convenient to radial location a pair slips 1, connected by bolt 4 between holder 2 and gland 3, the junction of holder 2 and gland 3 is provided with the gap of 2 ~ 3mm, both convenient for assembly like this.Can regulate the degree of tightness of slips again.The material of slips 1 is copper alloy, avoids the slips when drilling rod bias is more serious easily to damage.
Without any seal and bearing, processing is simple, and required precision is relatively low, and the job site more serious at dust is also not easily affected.
If the convenient fairlead damage in drilling process of field maintenance, only needs the attachment bolt unclamping base and gland, just can change fairlead slips or integral replacing fairlead.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to right.
