Description
Technical field
The utility model relates to the part of appliance of a kind of mud to annotating, and relates in particular to a kind of mud to annotating joint.
Background technology
The horizontal orientation crossing technology has obvious superiority when obstacles such as oil and gas pipes river crossing, lake, the main line of communication, railway terminal and important area.The general mud that adopts is to annotating technology in the present directed crossing construction; its technological principle is that rig driving drilling tool rotary goes back to when dragging reaming; mud is connected rotation to annotating joint one end with drilling pipe; the other end is connected with high-pressure rubber pipe and does not rotate; this moment the mud pumping plant with mud through high-pressure rubber pipe, to annotating in joint and the drilling pipe injection hole, to reach the purpose of protection hole wall, clear hole and flushing drill bit.Existing mud is to annotating joint as described in Figure 2, and its sealed bearing suit 2a is on high-pressure rubber pipe tube connector 1a, and is and affixed with drilling pipe tube connector 4a, filling sealing filler 3a between drilling pipe tube connector and high-pressure rubber pipe tube connector.In drilling pipe tube connector high speed rotary course, sealed bearing is with the rotation of drilling pipe tube connector, and its interior high-pressure rubber pipe tube connector of setting-in does not change.There is following shortcoming in present mud to annotating joint: the drilling pipe tube connector is by sealing filler and the setting-in high-pressure rubber pipe tube connector high speed rotary grinding in it, sealing filler consumes easily, after sealing filler damages the generation spillage, whole sealed bearing need be taken apart, change high-pressure rubber pipe tube connector and sealing filler, complex procedures, difficult in maintenance.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provides a kind of mud of being convenient to safeguard to annotating joint.
The utility model is to be achieved by the following technical programs:
A kind of mud is to annotating joint, the drilling pipe tube connector that comprises coaxial setting, high-pressure rubber pipe tube connector and sealed bearing, described drilling pipe tube connector is made of a transition tube connector and the drilling pipe end pipe that is connected its outer end, and the coaxial core pipe that is provided with sealed end insertion transition tube connector the inner and is tightly connected with it by sealing mechanism, described sealed bearing is sleeved on the transition tube connector, the core pipe holder of the ring-like radially end plate of the dismantled and assembled connecting band of sealed bearing, the link setting-in of described core pipe is gone in the hole of ring-like radially end plate, and described high-pressure rubber pipe tube connector is by being fixed with ring-like radially end plate with its affixed flange and being communicated with the core pipe.
Described sealing mechanism is made of the sealing filler and the gland spare that closely are filled between transition tube connector and the core seal of tube end, and described gland spare is connected with the inner port locking of transition tube connector.
Described sealing filler is a V-shaped seal ring.
Described gland spare by the position adjustments nut that cooperates with transition tube connector port, be pressed in the locking nut that has gland on the position adjustments nut and the gland of compression seal filler constitutes.
The beneficial effects of the utility model are:
Because described sealed bearing is sleeved on the transition tube connector, and sealing is pegged graft and to be fixed in core pipe on the core pipe holder on the transition tube connector, after high speed rotary grinding makes sealing filler damage the generation spillage, only need pull down core pipe holder and sealing mechanism, change core pipe and sealing filler, just can continue to use, convenient and swift, be convenient to safeguard; Adopt in addition by being filled in the sealing mechanism that sealing filler between transition tube connector and the core seal of tube end and gland spare constitute closely, described gland spare by the position adjustments nut that cooperates with transition tube connector port, be pressed in the locking nut that has gland on the position adjustments nut and the gland of compression seal filler constitutes, can maintain easily and adjust the tightness of sealing mechanism.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model.
Fig. 2 is the main TV structure schematic diagram of prior art.
Among the figure: 1. flange, 2. core pipe bracing frame, 3. gland, 4. position adjustments nut, 5. core pipe, 6. sealed bearing, 7.V RunddichtringO, 8. locking nut, 9. high-pressure rubber pipe tube connector, 10. transition tube connector, 11. drilling pipe end pipes, 1a. high-pressure rubber pipe tube connector, 2a. sealed bearing, 3a. sealing filler, 4a. drilling pipe tube connector, A. high-pressure rubber pipe, the B. drilling pipe.
The specific embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, the utility model is described in further detail below in conjunction with accompanying drawing and most preferred embodiment.
As shown in Figure 1, the utility model comprises the drilling pipe tube connector of coaxial setting, high-pressure rubber pipe tube connector 9 and sealed bearing 6, described drilling pipe tube connector is made of a transition tube connector 10 and the drilling pipe end pipe 11 that is connected its outer end, and the coaxial core pipe 5 that is provided with sealed end insertion transition tube connector the inner and is tightly connected with it by sealing mechanism, described sealed bearing 6 is sleeved on the transition tube connector 10, the core pipe holder 2 of the ring-like radially end plate of the dismantled and assembled connecting band of sealed bearing, the link setting-in of described core pipe is gone in the hole of ring-like radially end plate, and described high-pressure rubber pipe tube connector is by being fixed with ring-like radially end plate with its affixed flange 1 and being communicated with the core pipe.
