Abstract

The invention discloses a climbing aid, which belongs to the field of oil field workover equipment. The climbing aid comprises: a pull body (7) for connecting the index rope; the first pulley (3) and the second pulley (4) are all located on the first end (71) of the pull body (7). between the plate (1) and the second load-bearing plate (2), and can be in contact with the vehicle-mounted guy rope passing through the space between the first load-bearing plate (1) and the second load-bearing plate (2); the balance wheel support The first end (101) of (10) is connected with the weight cylinder (13), and the balance wheel (11) is located in the groove provided on the second end (102) of the balance wheel support (10); the balance track (9 ) through the gap between the balance wheel (11) and the bottom of the groove, its two ends are connected with the two ends of the balance bar (8) one by one, the balance bar (8) and the second end of the pull body (7) (72) Fixed connection. The invention can effectively avoid the entanglement of the index rope connected with the climbing aid and the vehicle-mounted guy rope.

Description

technical field [0001] The invention relates to the field of oil field workover equipment, in particular to a climbing aid. Background technique [0002] During workover in the oil field, it is often necessary for the derrick worker to climb to the second-floor platform of the derrick to perform operations such as lifting and lowering the tubing, salvaging and unblocking. In order to enable the derrick worker to climb the derrick more labor-savingly and get down from the derrick to the ground more safely, the derrick worker is often equipped with a climbing aid. [0003] related technologies, such as figure 1 As shown, the climbing aid includes a body 01 , two mounting plates 02 , two pulleys 03 and two bolts 04 . The structure of the main body 01 is a hollow structure, and heavy objects are placed inside the main body 01; two mounting plates 02 are installed on the outer wall of the main body 01 oppositely, there is a distance between the two mounting plates 02, and one o...
