Embodiment 1

[0055] Step 7: On the waist belt main body 1, add adhesive pull rings 10, 18 on the outside of the tightening mechanism on each side symmetrically, pass the stretching lines 11, 16 through the connecting plate 3, One end of 8 is fixed with the fixing wire ring 9,17 of said bonding draw ring 10,18 of this side, promptly obtained described double-side tightening waist belt that has been installed. Embodiment 1: Pull cord durability test

[0056] The waist circumference involved in the present invention and the waist circumference in the prior art were respectively tested for the durability of the tensile thread.

[0057] Test method: Fix the two waist belts on the waists of two mannequins of the same specification, and carry out repeated tightening, stretching and relaxing tests for 3,000 times at the same time. The standard for stretching and relaxation is to ensure that the length of the relaxed waistband is greater than the hip circumference, so as to simulate the actual use...

Abstract

The invention discloses a well drilling platform derrick climbing device. The well drilling platform derrick climbing device comprises a ladder, two pulleys, a safety rope, a buckle rope, two safety buckles and a counterweight block. The ladder is perpendicularly arranged on one side of the interior of a derrick. The two pulleys are supported in the positions, on the upper portion of the top end of the ladder, of the derrick through rotating shafts, and the radial central planes of the two pulleys are overlapped and are perpendicular to cross rods of the ladder. The safety rope surrounds in grooves of the two pulleys, one end of the safety rope is connected with the counterweight block, and the other end of the safety rope is connected with the middle of the buckle rope. The two ends of the buckle rope are provided with the safety buckles correspondingly, one of the safety buckles can be connected with a waistband tied on the waist of an operator in a buckled mode, and the other safety buckle can be connected with one cross rod of the ladder in a buckled mode. The well drilling platform derrick climbing device has the advantages of being simple in structure, convenient to use, low in cost, good in climbing effect and high in safety coefficient. The included waistband not only has the effect of a safety belt but also has the functions of waist protecting, health care, rehabilitation and instant communication.

Description

technical field [0001] The invention relates to safety equipment of a drilling platform, in particular to a safety equipment for drilling workers working at heights, which belongs to E21B. Background technique [0002] The drilling platform is the basic platform structure for oil and gas production operations. During the drilling construction process, drilling and lifting operations are required. Especially during the drilling process, workers need to climb to the drilling platform. When working at high altitude on the top of the drilling derrick, it is necessary to communicate with the personnel on the drilling platform below while bending down frequently. However, the safety belts used in the existing technology only have the function of preventing falling, and do not have the function of waist protection and health care. , and does not have the function of communication, and the staff basically rely on shouting to communicate, which greatly increases the labor intensity o...
