The invention discloses a climbing assistance device, and belongs to the field of oilfield workover rigs. According to the climbing assistance device, a pull body (7) is used for being connected witha drawing rope; a first pulley (3) and a second pulley (4) are located between a first bearing plate (1) and a second bearing plate (2) mounted at the first end (71) of the pull body (7) and can be incontact with a vehicle-mounted guy rope penetrating through the space between the first bearing plate (1) and the second bearing plate (2); the first end (101) of a balance wheel support (10) is connected with a weight increase weight barrel (13), and a balance wheel (11) is located in a groove formed in the second end (102) of the balance wheel support (10); and after a balance rail (9) penetrates through a clearance between the balance wheel (11) and the bottom of the groove, the two ends of the balance rail (9) are connected with the two ends of a balance rod (8) correspondingly, and the balance rod (8) is fixedly connected with the second end (72) of the pull body (7). By means of the climbing assistance device, the situation that the drawing rope connected with the climbing assistance device and the vehicle-mounted guy rope are wound can be effectively avoided.

    本发明公开了一种助爬器,属于油田修井设备领域。该助爬器包括:拉体(7)用于连接索引绳;第一滑轮(3)和第二滑轮(4)均位于拉体(7)的第一端(71)上安装的第一承重板(1)与第二承重板(2)之间,且均能与穿过第一承重板(1)与第二承重板(2)之间的空间的车载绷绳接触;平衡轮支座(10)的第一端(101)与加重砣筒(13)连接,平衡轮(11)位于平衡轮支座(10)的第二端(102)上设置的凹槽内;平衡轨道(9)穿过平衡轮(11)与凹槽的底部之间的间隙后,其两端与平衡杆(8)的两端一一连接,平衡杆(8)与拉体(7)的第二端(72)固定连接。本发明能有效避免与该助爬器连接的索引绳和车载绷绳发生缠绕。
