Abstract
The utility model discloses a cylinder driving and bearing mechanism for the connection of a derrick belonging to the technical field of connecting the upper body with the lower body of a derrick, which comprises a cylinder (2), a bearing block (3) and a connecting rod (1). When the derrick stretches out and the upper body (5) of the derrick rises to a specific position, the piston is compressed by the cylinder (2) and the bearing block (3) is driven to be placed on the bearing beam of the lower body (4) of the derrick. Then the upper body (5) of the derrick falls back to be placed on the bearing block (3). When the derrick retracts back and the upper body (5) of the derrick rises to a specific position, the piston extends out of the cylinder (2) and the bearing block (3) is driven to move to the outside of the lower body (4) of the derrick. Therefore, the upper body of the derrick can be smoothly retracted to the bottom thereof. The cylinder driving and bearing mechanism has the advantages of simple structure, convenient operation, environmental protection, energy conservation and reliable interlocking. The operation of the mechanism can be performed on the ground without being at a high position. Meanwhile, the bearing block (3) has a large bearing area and a high safety, which can improve the installation and dismounting efficiency of a telescopic derrick.
Description
One, technical field:
The utility model is that the air cylinder driven load carrier is used in a kind of derrick connection, belongs to derrick link technique field.
Two, background technology:
The form of structure that lower body connects with load carrier on the derrick was the spring drive-type in the past, promptly after the derrick upper body moves to ad-hoc location, drove a linkage by spring force, and carrier block stretches out automatically simultaneously, is sitting on the derrick lower body carrier bar; After setpoint distance was continued to move up in the derrick upper body, carrier block was withdrawn automatically.Because the spring link arrangement of mechanism in derrick internal work zone, has been compressed the activity space of miscellaneous part, and, also need work high above the ground that safety pin is installed for avoiding carrier block to withdraw automatically.Original this carrying form can't satisfy the requirement of derrick new product development.
Three, summary of the invention:
The utility model is exactly the problem that in use exists at load carrier, has designed a kind of derrick connection air cylinder driven load carrier.This load carrier is applicable to installing and using on oilfield drilling machine, workover rig derrick or other the telescopic suit derrick.The technical scheme that the utility model is taked is: a kind of derrick connects uses the air cylinder driven load carrier, form by cylinder (2), carrier block (3), connecting rod (1) etc., it is characterized in that cylinder (2) afterbody is fixed on above the derrick lower body (4) by bearing pin (6), piston in the cylinder (2) links to each other with connecting rod (1) one end, connecting rod (1) other end is connected with carrier block (3), carrier block (3) is fixed on derrick lower body (4) outside by bearing pin (7), Pneumatic controlled box one end is connected with source of the gas, and the other end is connected to above the cylinder (2).
The utility model is work like this: when derrick stretches out, after derrick upper body (5) rising arrived ad-hoc location, cylinder (2) compression piston drove carrier block (3) and is located on derrick lower body (4) carrier bar, fall after rise derrick upper body (5) again, is located on the carrier block (3); During the derrick withdrawal, after derrick upper body (5) rising arrived ad-hoc location, cylinder (2) stretched out piston, drove carrier block (3) and moved to derrick lower body (4) outside, and the derrick upper body can be withdrawn into the bottom smoothly.This apparatus structure is simple, and is easy to operate, environmental protection and energy saving, and interlocking is reliable, need not eminence in terrestrial operation during work, and in addition because carrier block (3) lifting surface area is big, the security performance height can improve telescope pole and install and removal efficiency.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a structural representation sectional view of the present utility model
Among the figure: 1, connecting rod; 2, cylinder; 3, carrier block; 4, derrick lower body; 5, derrick upper body; 6, bearing pin; 7, bearing pin.
Five, the specific embodiment:
Embodiment 1, a kind of derrick connect uses the air cylinder driven load carrier, form by cylinder (2), carrier block (3), connecting rod (1) etc., cylinder (2) afterbody by bearing pin (6) on be fixed on derrick lower body (4), piston in the cylinder (2) links to each other with connecting rod (1) one end, connecting rod (1) other end is connected with carrier block (3), carrier block (3) is fixed on derrick lower body (4) outside by bearing pin (7), and Pneumatic controlled box one end is connected with source of the gas, and the other end is connected to above the cylinder (2).
Claims (1)
1. a derrick connects and uses the air cylinder driven load carrier, belong to derrick link technique field, this mechanism is made up of cylinder (2), carrier block (3), connecting rod (1), it is characterized in that cylinder (2) afterbody is fixed on above the derrick lower body (4) by bearing pin (6), piston in the cylinder (2) links to each other with connecting rod (1) one end, connecting rod (1) other end is connected with carrier block (3), carrier block (3) is fixed on derrick lower body (4) outside by bearing pin (7), Pneumatic controlled box one end is connected with source of the gas, and the other end is connected to above the cylinder (2).
