Abstract
The invention provides a wheel-hidden-type pry seat. The wheel-hidden-type pry seat comprises a pry seat girder and wheels, wherein grooves are formed in lower parts of two ends of the pry seat girder, the wheels are arranged in the grooves of the pry seat girder, and the lowest positions of the wheels are higher than the lowest position of the pry seat girder. The grooves in the lower parts of two ends of the pry seat girder are of ladder-shaped grooves. The number of the wheels is at least four. The wheel-hidden-type pry seat has the beneficial effects that due to the adoption of the technical scheme, the pry seat is integrally placed on a drilling machine track by a crane, so that the wheels are guaranteed to freely move along the direction of the track, and the phenomenon of blocking and clamping are avoided; when the pry seat is used for transporting or maintaining working condition, the pry seat can be directly placed on a transport vehicle or the ground, the wheels are suspended at the moment, the operations of transporting or maintaining can be carried out without detaching the wheels, and the centre-of-gravity position of the pry seat is lower than that of a traditional pry seat, so that the safety is high and the operation is more convenient; and the wheel-hidden-type pry seat has the advantages of simple structure, convenience in repairing, low processing cost and the like.
Description
Technical field
The invention belongs to the oil-well rig equipment technical field, especially relate to a kind of built-in wheel minor skid.
Background technology
Skid is mainly used in the mud disposal system of land drill carriage, the basis of control system of rig.In existing technology, the plate armature that traditional rail mounted skid is comprised of shaped steel, wheel need to install separately.All will pull down wheel when each transportation or maintenance, construction period is longer.And wheel directly is installed below skid is made the height of C.G. of skid bigger than normal, make whole skid unstable when work, safety is lower.
Summary of the invention
The problem to be solved in the present invention provides a kind of built-in wheel minor skid, especially is fit to the wheel minor skid that the land drill carriage uses.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of built-in wheel minor skid, comprise skid crossbeam, wheel, below, described skid crossbeam two ends is provided with groove, described wheel is located in the groove of described skid crossbeam, and the lowest part of described wheel is higher than the lowest part of skid crossbeam.
Further, the groove of below, described skid crossbeam two ends is trapezoidal groove.
Further, the groove of below, described skid crossbeam two ends is the notch cuttype groove.
Further, the groove of below, described skid crossbeam two ends is circular groove.
Further, described wheel is more than four.
Further, described wheel is metal material.
Further, described wheel is steel wheel.
Advantage and good effect that the present invention has are: owing to adopt technique scheme, utilize crane that skid integral body is placed on the drilling rig rail, guarantee that wheel can move freely by direction along ng a path, without the blocked portion phenomenon; When transporting or when safeguarding operating mode, skid can directly be put on haulage vehicle or the ground, this moment, wheel was unsettled, need not dismantle the operation that wheel can transport or safeguard, and the relatively traditional skid of the position of centre of gravity of skid is lower, and is safe, more convenient to operate; Have simple in structure, easy to maintenance, the advantage such as processing cost is low.

Fig. 1 is the structural representation of duty of the present invention;
Fig. 2 is lateral view of the present invention;
Fig. 3 is that the present invention is at the structural representation of transportation or maintenance state.
Among the figure:
1, skid crossbeam 2, wheel 3, drilling rig rail
4, the plane of vehicle or ground
The specific embodiment
Shown in Fig. 1,2 and 3, a kind of built-in wheel minor of the present invention skid comprises skid crossbeam 1, wheel 2, and below, described skid crossbeam 1 two ends is provided with groove, described wheel 2 is located in the groove of described skid crossbeam 1, and the lowest part of described wheel 2 is higher than the lowest part of skid crossbeam 1.The groove of below, described skid crossbeam 1 two ends is trapezoidal groove.The groove of below, described skid crossbeam 1 two ends is the notch cuttype groove.The groove of below, described skid crossbeam 1 two ends is circular groove.Described wheel 2 is more than four.Described wheel 2 is metal material.Described wheel 2 is steel wheel.
The course of work of this example: skid crossbeam 1 is welded for H shaped steel, and its below, two ends is provided with groove, is provided with wheel 2 in the groove.More than plane on the skid, continue the equipment such as slurry tank, slush pump are installed, utilize crane that skid integral body is positioned on the drilling rig rail 3 after the installation, guarantee that wheel 2 can move by direction along ng a path freely, without jam.When transporting or safeguard operating mode, skid can directly be put on the plane or ground 4 of haulage vehicle, and at this moment wheel 2 is unsettled, need not dismantle the operation that wheel 2 can transport or safeguard, at this moment the position of centre of gravity of skid is low with respect to traditional skid, and safety is higher.The invention is mainly used in the land drill carriage.
More than one embodiment of the present of invention are had been described in detail, but described content only is preferred embodiment of the present invention, can not be considered to be used to limiting practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve etc., all should still belong within the patent covering scope of the present invention.
