Abstract
The utility model belongs to the technical field of the oil mechanical equipment, which is a assistor for the ladder ascension of an oil drilling derrick. The utility model comprises a bracket, a rope guiding wheel, a steel rope, a power device and a safety belt; the bracket is connected with the upper end of the lifting frame of the overhead crane of the derrick; the rope guiding wheel is mounted on the terminal end of the bracket; one end of the steel rope is connected with the power device after bypassing the rope guiding wheel; the other end is connected with the safety belt; the power device is a counterweight, the guy line of the derrick passes through the power device and the power device can slide along the guy line. The power device consists of two chain wheels and the counterweight; the chain wheels are connected with the counterweight; the guy line passes through the clearance between the two chain wheels and the counterweight, which makes the two chain wheels slide along the guy line of the derrick. The assistor for the ladder ascension of the oil drilling derrick is connected with the lifting frame of the overhead crane with a simple structure, which requires no independent mounting and dismounting. During the application, the safety belt is tied on the ladder climbing person; with the help of the assistor, the ladder ascending difficulty for the ladder climbing person is reduced and the safe belt also has the safety and protection function.
Description
Technical field
The utility model belongs to the petroleum machinery equipment technical field, specifically is a kind of oil drilling and repairing machine derrick ascending stair booster.
Background technology
Derrick is the important component part of oil drilling and repairing machine, be mainly used in erecting equipment and instruments such as laying and hang overhead traveling crane, tourist bus, hook, lay and hang mud circulation equipment and instruments such as standpipe, water tap, hose, bear make a trip, setting of casing, load that salvaging and other operations produced, the height and the space that make a trip and deposit the thribble operation are provided, handle drillng operations such as down-hole accident.Derrick height generally between 30～45 meters, in the drillng operation, often needs workman's ascending stair climbing derrick to carry out operation.Along with the further raising that oil drilling and repairing machine functional performance is required, the derrick annex is more and more obvious to the trend of human oriented design, and the ascending stair booster is set on derrick, thereby reduces workman's ascending stair difficulty, cooperate falling proof device to play safety effect again, very necessary.
Summary of the invention
The purpose of this utility model provides a kind of oil drilling and repairing machine derrick ascending stair booster, can reduce ascending stair personnel ascending stair difficulty, has the security protection effect simultaneously.
For achieving the above object, technical solutions of the utility model are:
A kind of derrick ascending stair booster, comprise support, sheave, wire rope, booster, safety belt, support is connected the upper end of derrick top overhead traveling crane crane boom, sheave is installed in bracket end, wire rope is walked around back one end from sheave and is connected booster, and other end attachment security band, booster are a mass, derrick guy wire passes from booster, and booster can be slided along derrick guy wire.
Described booster is made up of two pulleys, balancing weights, and two pulleys are connected with balancing weight, and derrick guy wire passes from the gap between two pulleys and the balancing weight, and two pulleys can be slided along derrick guy wire.
This derrick ascending stair booster is connected on the overhead traveling crane crane boom, simple in structure, installing/dismounting (with overhead traveling crane crane boom dismounting) separately, during use, safety belt is lain on one's body the ascending stair personnel, by means of booster weight, alleviated ascending stair personnel ascending stair difficulty, safety belt has played the security protection effect.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the zoomed-in view of Y among Fig. 1.
The specific embodiment
As Fig. 1, shown in Figure 2, the utility model comprises support 1, sheave 2, wire rope 3, booster 4, safety belt 5, support 1 is connected the upper end of the overhead traveling crane crane boom 7 on derrick 8 tops, sheave 2 is installed in the outer end of support 1, wire rope 3 is walked around back one end from sheave 2 and is connected booster 4, other end attachment security band 5, booster 4 is by two pulleys 41,42, balancing weight 43 is formed, two pulleys 41,42 are connected with balancing weight 43, derrick guy wire 6 is from two pulleys 41,42 and balancing weight 43 between the gap pass, make two pulleys 41,42 can slide along derrick guy wire 6.Safety belt 5 has non-slip hook.When the ascending stair personnel climb derrick, fasten seat belts 5, be connected with wire rope 3 by non-slip hook.Under booster 4 actions of gravity, 3 couples of ascending stair personnel of wire rope produce one to upper pulling force during ascending stair, thereby reduce ascending stair personnel ascending stair difficulty, and safety belt 5 also plays the security protection effect simultaneously in the ascending stair process.
