Abstract

The utility model discloses a gate ramp drill stem rest platform in low-position adjustment and control. A bent plate is fixedly connected to the lower end of an edge beam of a ramp, a plurality of sets of branch plates are fixedly connected to the edge beam of the ramp at even intervals, each branch plate is provided with a preset channel, the channels are communicated with one another, and upper connection rods are arranged in the channels in a penetrating mode; the upper portions of the upper connection rods are fixedly connected with a drill stem rest platform body, the upper connection rods are connected with lower connection rods, and the lower connection rods are connected with the bent plate. The structure of the gate ramp drill stem rest platform achieves mechanical overturn of the gate ramp drill stem rest platform in low positions according to use requirements, and is low in cost input, easy and convenient to operate, safe and reliable, and wide in application range.

Description

A kind of gate slope drilling rod rest ledge of low level regulation and control

Technical field

The utility model belongs to the petroleum machinery equipment technical field, relates to a kind of gate slope drilling rod rest ledge of low level regulation and control.

Background technology

The rig gate slope is the vitals of oil-well rig.Existing rig gate slope drilling rod rest ledge adopts upset manually, and in dilatory drilling tool process, there are very large unsafe factor in an artificial high position, manual overturning drilling rod rest ledge, also are unfavorable for increasing work efficiency.

The utility model content

The purpose of this utility model is to provide a kind of gate slope drilling rod rest ledge of low level regulation and control, has solved artificial high-order, the manual overturning of available technology adopting, dangerous, ineffective problem.

The technical scheme that the utility model adopts is, a kind of gate slope drilling rod rest ledge of low level regulation and control, side bar lower end in ramp is fixedly connected with bent plate, on the side bar in ramp, evenly interval is fixedly connected with many group support plates, be preset with the passage of ganging up on each support plate, in this passage, be installed with connecting rod; Upper connecting rod epimere is fixedly connected with the drilling rod rest ledge, and upper connecting rod is connected with lower link, and lower link is connected with bent plate.

The gate slope drilling rod rest ledge of low level regulation and control of the present utility model is further characterized in that:

Between lower link and bent plate, by safety pin, be located by connecting.

Between upper connecting rod and lower link, by rotating shaft, connect.

The beneficial effects of the utility model are: broken the design of the high bit flipping of conventional rig substructure ramp drilling rod rest ledge, realized that low level is to gate slope drilling rod rest ledge mechanical overturn according to requirements, the low-cost input; Easily and fast realize the requirement of drilling rod rest ledge field operation, easy and simple to handle, safe and reliable, applied range, be applicable to various model gate slopes that rig substructure is joined.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

With reference to Fig. 1, Fig. 2, the gate slope drilling rod rest ledge structure of low level regulation and control of the present utility model is, comprise ramp 1, drilling rod rest ledge 2, upper connecting rod 3, lower link 4, support plate 5, bent plate 6, rotating shaft 7, safety pin 8, on the side bar in ramp 1, evenly interval is fixedly connected with many group support plates 5, in ramp, 1 side bar lower end is fixedly connected with bent plate 6, be preset with the passage of ganging up on each support plate 5, in this passage of ganging up, be installed with connecting rod 3;

Upper connecting rod 3 epimeres are fixedly connected with (see Fig. 5, adopt welding manner fix) with drilling rod rest ledge 2, upper connecting rod 3 is connected (see figure 6) with lower link 4 by rotating shaft 7, and lower link 4 is by safety pin 8 and bent plate 6 (see figure 7) that is located by connecting.

With reference to Fig. 3 and Fig. 4, the course of work of the utility model device is, when drilling rod rest ledge 2 needs upset, the safety pin 8 that operating personnel are connected between lower end position (low level) removes lower link 4 and bent plate 6, rotate lower link 4 around the shaft 7 upwards to upper connecting rod 3 upright positions, can drive the low bit flipping that 2 upsets of drilling rod rest ledge realize drilling rod rest ledge 2 left again or the upper connecting rod 3 that turns right.
