Abstract
The utility model relates to a device used for grabbing a drill rod in well drilling equipment in an oilfield, in particular to a drill rod holding device used for drill rod racking. The utility model adopts the technical scheme that more than one guiding shafts are fixed on the two sides of a connecting block in a penetrating manner; the guiding shafts on the two sides of the connecting block are respectively sleeved with holding blocks, surfaces on the same sides of the connecting blocks extend from at least one end of the two holding blocks on the same side, slip inserts are separately arranged on the opposite surfaces of the extended parts, and a driving mechanism extending and stretching in the direction of the guiding shafts is arranged between the holding blocks. Through controlling and operating the driving mechanism (a hydraulic cylinder or a pneumatic cylinder, a motor drive and the like), the utility model achieves the opening and the closing between the holding blocks, thereby achieving the effect of releasing and grabbing a drill rod; and the drill rod holding device can be used together with a hoisting mechanism in the prior art, can also be served as associated equipment for totally solving the problems in full mechanization and automation progresses of a drill rod racking system, and can also well solve the problem of drill rod bearing and dimensions during the drill rod racking process.
Description
Technical field
The utility model relates to the device that is used to grasp drilling rod in a kind of oil drilling equipment, a kind of drill rod grip device that is used for pipe racking of saying so more specifically.
Technical background
Pipe racking be in the drilling process drilling rod from the discharging frame move to well head or from well head move to the discharging frame necessary process.At present in the drillng operation drilling rod work that to put be that the workman operates elevator, be connected to the box cupling place of drilling rod by elevator, sling (or transferring) drilling rod to assigned address by lifting machinery then, again by workman's release elevator of seting out, this extracting and to discharge the drilling rod operation abnormally dangerous and labour intensity is big, operating efficiency is also very low.In order to address this problem, the applicant begins to carry out research, design and the development experiments of drilling rod overall process machinery automatic discharge device around the actual needs of drilling operation course.Realize effectively that for this reason drilling rod mechanization is grasped and the drill rod grip device (or being called manipulator) of release is the primary problem that solves.
The utility model content
The purpose of this utility model is exactly to grasp and the existing problem of release drilling rod at artificial dislodging elevator, proposes a kind of drill rod grip device of Fully-mechanized operation.
Its technical scheme is: run through being fixed with an above axis of guide in the contiguous block both sides, be respectively installed with grip block on the axis of guide of both sides, at least one stretches out the ipsilateral of contiguous block with side at two grip blocks, and be respectively equipped with slip insert at the opposite face of extension, between two grip blocks, also be provided with along the flexible driving mechanism of axis of guide direction.
The improvement project of such scheme also comprises: two grip blocks and the axis of guide are and are slidingly matched, and the driving mechanism that is provided with between two grip blocks is a two-way hydraulic cylinder.Between two grip blocks and the axis of guide one fixing, another is for being slidingly matched, the driving mechanism that is provided with between two grip blocks is unidirectional hydraulic cylinder.The slip insert and the grip block that are provided with on grip block are structure as a whole, and perhaps are the branch body structure by bolt, and slip insert is an arc.
The utility model is by operation control driving mechanism (hydraulic cylinder or pneumatic linear actuator, motor-driven etc.), realize the switching between the grip block, reach drilling rod is discharged and grasps, both can be used with existing derricking gear, also can provide supporting, and can be good at solving drilling rod load-bearing and dimensional problem in the pipe racking process for Fully-mechanized, the automated process that solves pipe pick up and lay down system comprehensively.
Description of drawings
Fig. 1 is the overall structure schematic diagram of a kind of exemplary embodiments of the utility model;
Fig. 2 is the grip block structural representation of Fig. 1;
Fig. 3 is the contiguous block structural representation of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description:
With reference to Fig. 3 and Fig. 1, contiguous block 4 is L shaped for steel plate processing, its welding convex edge, top, three axis holes are set on the steel plate, be used for the interspersed axis of guide 2, the top is provided with keyhole in order to being connected with miscellaneous equipment, and the prefabricated notch of Lower Half leaves the space for horizontally disposed hydraulic cylinder 5.With reference to Fig. 2 and Fig. 1, two rectangular structure that grip block 3 is processed for steel plate, be shaped on three axis holes that are slidingly matched with the axis of guide 2 above equally in advance, symmetry is sleeved on the axis of guide 2 of contiguous block 4 both sides, the left-hand end of grip block 3 is stretched out, form grasping part, be used for being provided with arc slip insert 1 on its opposite face, cooperate with the clamping of drilling rod wall by slip insert 1.Hydraulic cylinder 5 is horizontally set between two grip blocks 3, and it stretches by operation control, reaches the purpose that 3 pairs of drilling rods enforcements of control grip block discharge and grasp.
On the basis of the foregoing description, the utility model has also proposed other improvement project.One is that two grip blocks and the axis of guide are and are slidingly matched, and the driving mechanism that is provided with between two grip blocks is a two-way hydraulic cylinder, can realize two grip block synchronization actions like this.Two be between two grip blocks and the axis of guide one fixing, another is for being slidingly matched, the driving mechanism that is provided with between two grip blocks is unidirectional hydraulic cylinder, can realize that so single grip block moves.The 3rd, the slip insert and the grip block that are provided with on grip block are structure as a whole, and perhaps are the branch body structure (being convenient to change slip insert) by bolt, and slip insert is an arc, decide on concrete caliber size.The 4th, the axis of guide that runs through grip block and contiguous block has at least one to be the empty axis of guide, is used so that be connected with other device.
Its operating principle is that the grip block front end is equipped with slip insert, under the effect of hydraulic cylinder, along the parallel mobile do unlatching of the axis of guide, closing motion.The axis of guide is installed on the contiguous block, grip block is risen support and guide effect.
Claims (4)
1, a kind of drill rod grip device, it is characterized in that: run through being fixed with an above axis of guide in the contiguous block both sides, be respectively installed with grip block on the axis of guide of both sides, at least one stretches out the ipsilateral of contiguous block with side at two grip blocks, and be respectively equipped with slip insert at the opposite face of extension, between two grip blocks, also be provided with along the flexible driving mechanism of axis of guide direction.
2, drill rod grip device according to claim 1 is characterized in that: two grip blocks and the axis of guide are and are slidingly matched, and the driving mechanism that is provided with between two grip blocks is a two-way hydraulic cylinder.
