Abstract
A folding mechanism for a mast of a rotary drilling rig comprises a base, a bracket, a fixing device, an oil cylinder and an oil cylinder balance valve, wherein the base, the bracket and the oil cylinder form a triangular connecting mechanism; in the folding mechanism, the folding and the extension of the mast is realized through an external oil source; and the oil cylinder is to be connected with the oil cylinder balance valve. The utility model has the benefits that the triangular connecting mechanism is adopted, the relative position of the bracket is adjusted through the expansion and the contraction of the oil cylinder, and the triangular connecting mechanism is fixed through pin shafts and bolts in different positions, so that the operation of unscrewing or screwing fixing bolts in corresponding connecting parts during the folding of the mast is eliminated, and the disassembly, the assembly and the transportation are more convenient.
Description
Technical field
The utility model relates to technical field of engineering machinery, relates in particular to that a kind of rotary drilling rig mast is fixed, fold mechanism.
Background technology
Referring to Fig. 1, the present situation of present rotary drilling rig ubiquity mast overlength, constant transportation, so in existing overwhelming majority design, generally adopt pulley yoke 1 ' mast is turned back, pulley yoke 1 ' with mast between the joint the hinged mode of employing be connected, when transition, need dismantle connecting bolt by manpower, and make pulley yoke around the pin joint inflection, again with joint and pulley yoke on the thread connecting mode fixed mast, to avoid swing at transportation middle pulley frame; Otherwise then, though this scheme can solve the transportation problem of mast overlength, because the pulley yoke deadweight is bigger, have operation inconvenience in dismounting, installation process during assembling, be limited to the instructions for use of high-strength bolt, the man-hour that is produced is more, expense is higher.And in disassembly process, mostly be liftoff operation, have certain danger.
The utility model content
Technical problem to be solved in the utility model is, overcomes problems of the prior art, and a kind of novel rotary drilling rig mast fold mechanism is provided, solving existing rotary drilling rig in the pulley yoke disassembly process, and poor efficiency, high-risk situation.
In order to address the above problem the technical solution of the utility model is such:
Rotary drilling rig mast fold mechanism comprises that is fixed on a base that saves on the mast, and base is provided with assembly pulley, it is characterized in that, and the also hinged support of joint on the mast, the support upper end is provided with an assembly pulley; Hinged one telescopic oil cylinder on the described base, the other end of oil cylinder connects the assembly pulley of support upper end, and described base, support and oil cylinder form a triangle bindiny mechanism.
Described oil cylinder also connects an equalizing valve that prevents the oil cylinder catastrophic failure, the external hydraulic oil source of described oil cylinder.
Described oil cylinder connection one is arranged on the control crank of rotary drilling rig driver's cabin.
Beneficial effect, the utility model adopts the technical scheme in the dismounting of rotary drilling rig mast, when carrying out the dismounting of mast, utilize this folding system, the assurance system can carry out dismounting to mast effectively in the shorter time, to satisfy field requirement, reduce cost of use, reduce application risk.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is existing Spiral digging machine mast folding process schematic diagram;
Fig. 2 is a rotary drilling rig mast fold mechanism structural representation described in the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of rotary drilling rig mast fold mechanism comprises base 1, support 2, oil cylinder 3, base 1 is fixed on the mast 4 and saves the top, support 2 also is arranged on the mast 4 and saves the top, and support 2 is connected on the mast 4 by bearing pin 5 and saves the top, and the upper end of support 2 is provided with an assembly pulley; Base 1 is provided with assembly pulley, and base 1 also connects a telescopic oil cylinder 3 by a bearing pin 6, and the other end of oil cylinder 3 connects the assembly pulley of support 2 upper ends by a bearing pin 7.
Described base 1, support 2 and oil cylinder 3 form a triangle bindiny mechanism, and be middle by bearing pin 5, bearing pin 6, bearing pin 6 connections.Described fold mechanism is realized the folding of mast and stretches out that by connecting external oil sources described oil cylinder 3 should connect an oil cylinder equalizing valve, prevents the oil cylinder catastrophic failure.Oil cylinder can be single or multiple, and equalizing valve can be cancelled or be a plurality of.This programme adopts the mode of single oil cylinder and single equalizing valve.
Base 1 links to each other by oil cylinder 3, bearing pin 5, bearing pin 6, bearing pin 7 with support 2, and form a triangle bindiny mechanism, when needs are adjusted the pulley yoke relative position, handle the control crank (not indicating among the figure) that driver's cabin is installed, stretching of control oil cylinder 3 reached the purpose of adjusting the pulley yoke position.
The utility model adopts the technical scheme in the dismounting of rotary drilling rig mast, when carrying out the dismounting of mast, utilizes this folding system, the assurance system can carry out dismounting to mast effectively in the shorter time, to satisfy field requirement, reduce cost of use, reduce application risk.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
