Background
The power catwalk is conveying equipment used in the technical field of oil and gas drilling and production equipment, and can convey drilling tools on bent frames (supporting legs) on two sides of a catwalk main body to a drilling floor and also convey and arrange the drilling tools on the drilling floor to the bent frames (supporting legs) on two sides of the catwalk main body; such as chinese patent CN201520866530.4, a power catwalk; chinese patent CN201420525189.1, an oil cylinder lifting type land power catwalk; chinese patent CN201420660266.4, a rack and pinion drill power catwalk.
The main driving system of the power catwalk is a driving mechanism for enabling a V-shaped drilling tool supporting beam to ascend/descend so as to facilitate a sliding shoe on the V-shaped drilling tool supporting beam to convey a drilling tool to a drilling floor, such as a main driving pulley of chinese patent CN 201520866530.4; like the pulley and pulley cylinder of Chinese patent CN 201420525189.1; like the pulley and the radial arm cylinder of the Chinese patent CN 201420660266.4.
The reason why the power catwalk in the prior art is large is that the support beam of the V-shaped drilling tool needs to have a certain length in order to meet the transportation requirements of the drilling tool, and the support beam of the V-shaped drilling tool needs to have a certain length in order to be matched with the base so as to facilitate the middle transfer process of the drilling tool.
In order to reduce the size of the power catwalk, the applicant designs a power catwalk, wherein a V-shaped drilling tool supporting beam is of a folding structure and is called as a folding V-shaped drilling tool supporting beam, and the folding V-shaped drilling tool supporting beam comprises an upper supporting beam section and a middle supporting beam section which are hinged with each other; when the front end of the middle-lower section of the supporting beam moves to the top end of the ramp, the front end of the upper section of the supporting beam moves upwards along the front surface of the ramp until the upper section of the supporting beam passes through the upper part of the ramp, and the turning-over type V-shaped drilling tool supporting beam is flattened as shown in figure 7 so as to convey a drilling tool to the drilling floor; when the front end of the middle-lower section of the supporting beam moves to the bottom end of the ramp, the front end of the upper section of the supporting beam moves downwards along the front surface of the ramp, the turnover type V-shaped drilling tool supporting beam is gradually turned over until the middle-lower section of the supporting beam is matched on the base, and the upper section of the supporting beam is matched on the ramp, as shown in fig. 8, so that the drilling tool is conveniently transferred onto the turnover type V-shaped drilling tool supporting beam (specifically onto the middle-lower section of the supporting beam).
Because of the design in order to adopt the folding V type drilling tool supporting beam, a supporting beam upper segment just need not cooperate on the base, so the base size of power catwalk has just so reduced, and the size of power catwalk has just also reduced, can also reduce V type drilling tool supporting beam's movement route simultaneously.
