Abstract
The utility model relates to a folding lift type catwalk for a drilling machine, and belongs to the field of petroleum drilling equipment machines. The problem that a catwalk cannot be directly used as a lifting platform of a high-altitude lifting well frame in the prior art is solved, and the folding lift type catwalk for the drilling machine is provided, so that the catwalk can be folded to be the height of a normal catwalk when the drilling machine works; when a drilling machine well frame lifts and descends, the catwalk also can be raised to required height, so that a platform of equipment such as traveling blocks, large hooks and the like is provided; the device comprises a base, a platform, a front stay bar, a rear stay bar, an inclined stay bar and a ladder; the base, the platform, the front stay bar and the rear stay bar are connected with a lug plate by virtue of pins to form a parallelogram structure; the upper end of the inclined stay bar has a rotational shaft structure; the lower end of the inclined stay bar has a circular arc surface structure; a rotational shaft at the upper end of the inclined stay bar can rotate in a rotation hole of the front stay bar; and the circular arc surface at the lower end of the inclined stay bar can slide in a concave slideway on the base.
Description
Technical field
The utility model belongs to the oil-well drilling equipment mechanical field, is specifically related to a kind of folding liftable churn cat road.
Background technology
The cat road is one of peripheral matched equipment of rig, be mainly used in drilling tool and transfer to rack for rods from rig floor, or while from rack for rods, transferring to rig floor, the platform ，Mao road that drilling tool is provided in the middle of providing is generally the stationary structure contour with rack for rods.For the high-order drilling derrick hoisted from drilling floor surface, before derrick lifting, the equipment such as the tourist bus after wire rope handling, hook need to be placed on the platform of certain altitude, the height of platform generally should approach the height of drilling floor surface, and platform is generally to consist of two higher supports and the rig cat road be placed on support.Before derrick hoists at every turn or transfers, all need first to put up such platform, taken a large amount of human and material resources and time; And when derrick lifting, along with the movement of the equipment such as tourist bus, hook, be placed on the easily landing from support of support Shang Demao road, equipment and personnel's safety is threatened.In order to save derrick lifting and to transfer the time, improve the safety of derrick lifting, be necessary to develop a kind of folding liftable churn cat road.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art and a kind of folding liftable churn cat road is provided, and makes rig ，Gai Mao road when operation can be folded into the height in normal cats road; When drilling derrick hoists and transfer, the ，Gai Mao road can be elevated to again the height needed, and the platform of equipment such as placing tourist bus, hook is provided.
The purpose of this utility model is achieved in that a kind of folding liftable churn cat road, comprise base, platform, front strut, rear pole, hound and ladder, it is characterized in that: base is connected with the front strut lower end by pin one, and the front strut upper end is connected with platform by pin two; Base is connected with the rear pole lower end by pin three, and the rear pole upper end is connected with platform by pin four; Be provided with the spill slideway on base, spill slideway front end is provided with fixed ear base; Front strut top is connected with the upper end of hound by axis of rotation, and the lower end of hound is flexibly connected by pin five and ear seat; End at base is provided with ladder.
The connected mode of described spill slideway and fixed ear base is welding.
The length of described front strut is identical with the length of rear pole.
The connected mode of described spill slideway and base is welding.
The lower end of described hound is downward outstanding arcuate structure.
Wherein base, platform, front strut and rear pole are connected with the ear seat by pin, form parallelogram sturcutre; The hound upper end is revolute axes configuration, lower end is the arc surface structure, the axis of rotation of hound upper end can rotate in the rotating hole of front strut, the arc surface of hound lower end can slide in the spill slideway on base, the spill slideway is welded on base, and spill slideway front end is welded with fixed ear base.Dang Mao rises in road while being raised to a high position, and the arc surface of hound lower end slides into the fixed ear base position, with pin, connects hound lower end and fixed ear base, makes the hound location, thereby makes the parallelogram sturcutre location; When low level is transferred in needs cat road, take off the pin that connects hound lower end and fixed ear base, can transfer the cat road, make plane contact on platform and base, reach low level.
The utlity model has following advantage: 1 ,Gai Mao road is simple in structure, easy to operate, uses general hanging device can complete rising and the decline of platform; 2 ,Mao roads are when a high position, and base, platform, front strut and rear pole connect into parallelogram sturcutre with pin, and make parallelogram sturcutre location with hound, are connected firmly, safe and reliable; 3 ,Mao road high-end trim being for the hoisting and transfer the normal operation for rig as general cat road of ，Mao road low-end trim of derrick, a kind of equipment, and two kinds of purposes, improved the utilization rate of equipment.
The accompanying drawing explanation
Fig. 1 is cat of the present utility model road high-end trim figure.
Fig. 2 is the lifting process state diagram of cat of the present utility model road.
Fig. 3 is cat of the present utility model road low-end trim figure.
The specific embodiment
As shown in Figure 1, 2, 3, a kind of folding liftable churn cat road, comprise base 1, platform 2, front strut 3, rear pole 4, hound 5 and ladder 6, it is characterized in that: base 1 is connected with front strut 3 lower ends by pin 1, and front strut 3 upper ends are connected with platform 2 by pin 28; Base 1 is connected with rear pole 4 lower ends by pin 3 14, and rear pole 4 upper ends are connected with platform 2 by pin 4 13; Be provided with spill slideway 9 on base 1, spill slideway 9 front ends are provided with fixed ear base 10; Front strut 3 tops are connected with the upper end of hound 5 by axis of rotation 12, and the lower end of hound 5 is flexibly connected by pin 5 11 and ear seat 10; End at base 1 is provided with ladder 6.Described spill slideway 9 is welding with the connected mode of fixed ear base 10.The length of described front strut 3 is identical with the length of rear pole 4.Described spill slideway 9 is welding with the connected mode of base 1.The lower end of described hound 5 is downward outstanding arcuate structure.
