Abstract
The utility model discloses a drilling platform derrick load test bearing connecting tool. A main body is a circular ring (1) of which the inner diameter is 280mm, the outer diameter is 600mm and the thickness is 180mm; hooks (2) are arranged on the two sides of the upper half part of the circular ring, and the inner sidewalls of the hooks (2) are circular-arc-shaped. When the drilling platform derrick load test bearing connecting tool is in use, the circular ring arranged at the lower ends of two lifting arms of a top drive on a derrick is connected with the two hooks of the tool; a large-tonnage heavy object is connected with the circular ring of the tool. The tool is used for transferring a large-tonnage load lifted in a test to the two lifting arms in a balanced manner so as to guarantee the safety of the test. For ensuring that the hooks are steadily connected with the circular ring arranged at the lower ends of the lifting arms, the inner sidewalls of the hooks are machined into the shape of a circular arc so that the hooks can be matched with the circular ring arranged at the lower ends of the lifting arms in a bedding-in manner.
Description
Technical field:
The utility model relates to a kind of in the time of drilling platform derrick test under load, drives and the frock of large-tonnage weight for connecting top on derrick.
Background technology:
The large-scale derrick test under load of drilling platform is the functional trial carrying out after drilling platform completion.Need in test to utilize the hook top on derrick to drive by the lifting of large-tonnage weight, to verify intensity and the hook enhanced feature of derrick.The derrick hoisting capacity of drilling platform has reached 900 tons at present, and what have even exceedes 1000 tons.For this being loaded safely, successfully transferring on derrick, must guarantee to push up and drive and firm connection of loading, be also the key of these experiment success or failure.
Summary of the invention:
The utility model is when guaranteeing large-scale derrick test under load, and drive and firm connection of loading on top, provides a kind of intensity high, loads and unloads bearer connection frock efficiently.
Technical solution of the present utility model is: a kind of drilling platform derrick test under load bearer connection frock, and main body is an annulus, and internal radius is 280mm, and external diameter is 600mm, and thickness is 180mm; Both sides in annulus the first half are provided with hook, and the madial wall of hook is circular-arc.
When the utility model uses, the annulus of two arm lower ends and two hooks of this frock that top on derrick is driven are connected, and large-tonnage weight is connected with the annulus of this frock.The large-tonnage load balancing that this frock promotes experiment is transferred on two arms, guarantees experiment safety.In order to guarantee hook and the annulus stable connection of arm lower end, the madial wall of hook is processed into circular-arc, carry out bedding-in with the annulus of arm lower end.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is block diagram of the present utility model.
The specific embodiment:
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, 2, a kind of drilling platform derrick test under load bearer connection frock, main body is an annulus 1, and internal radius is 280mm, and external diameter is 600mm, and thickness is 180mm; Be provided with hook 2 in the both sides of annulus the first half, the madial wall of hook 2 is circular-arc.
When application, at annulus 1 place of this frock, shackle is installed.Shackle lower end connects large-tonnage load by steel rope.By this frock, the large-tonnage load that experiment is promoted is transferred on two arms, guarantees to push up and drives stress equalization, thereby guarantee carrying out smoothly of test.
Claims (1)
