SU1579973A1 - Receiving bridge of drilling unit - Google Patents

Abstract

The invention relates to drilling equipment. The purpose of the invention is to reduce the time for installation and disassembly of the bridge and increase its maneuverability. The receiving bridge contains a horizontal gangway (GT) 1 with truss racks 8 installed on its sides. One of the sides of the GT 1 is connected to the racks 8 by means of hinges 9. On the racks 8 a lifting mechanism 5 is installed. The racks 8 and GT 1 represent a single platform mounted on carriages that moves in guides. By means of the articulated tg 14, the platform is connected with the tower block 15. To ensure the passage of the fountain fountain GT 1, the mechanism 5 is rotated by hinges 9 and fixed in a vertical position. The bridge is then brought back to its original position. 1 hp f-ly, 3 ill.

The invention relates to the field of drilling, namely to receiving bridges of drilling rigs.

The purpose of the invention is to reduce the time for installation and disassembly of the bridge and increase its maneuverability.

Figure 1 shows the receiving bridge, side view; figure 2 is the same, top view; on fig.Z - section aa in figure 1.

The receiving bridge of the drilling rig consists of a working ladder 1, an upper 2 and a lower 3 visors, an instrumental platform 4, a lifting mechanism 5, half-platforms 6 and 7. The lower peak 3 is tarnishly connected to the working ladder 1. The semi-platforms 6 and 7 each have three trusses, which function as shelves for storing pipes, a mechanism 5 is installed on them. The trusses of the half-platform 6 are connected to the working ramp 1 on one side by the hinges 9, and the trusses of the half-platform 7 have stops 10 for fixing the working ladder 1 in a horizontal position. The semi-platforms 6 and 7 are rigidly interconnected by the front 11 and rear 12 arches, forming a single platform. On the rear arch 12 is installed a latch 13 for fixing the working ladder 1 in a vertical position. The platform is connected by means of hinge joints, g 14, to the tower block 15 and mounted on transport carriages 16, which move along rails 17.

Work in moving the receiving bridge to a new well point is carried out as follows.

To ensure the passage of flowering armature (not shown) installed at the mouth of the drilled well during the process of shifting the receiving bridge to a new well-point, the lower visor 3 is installed in a horizontal position and stops relative to the working ladder 1. Then, the upper visor 2 is necessary using a lifting mechanism 5 or

lift the auxiliary drawworks (not shown) to a height sufficient to recline the working ladder 2 and hang it on a cable (not shown) to the tower block 15. The working drain 1 together with the lower visor 3 is mounted in a vertical position and is locked with a latch 13. The receiving bridge is moved simultaneously with the tower block 15. Then the bridge is moved to its original position.

The proposed design of the receiving bridge, used in well drilling, reduces the time of installation and dismantling, eliminates the use of special equipment for reassembling the receiving bridge and delivering it to the work site, makes it possible to shift the installation in the direction opposite to the receiving bridge. Hinge bolts provide the ability to quickly fasten a bridge to a block and, as a mount, are more reliable when the block or bridge is moved when moving.

Claims (2)

1. Receiving bridge of a drilling rig, made in the form of a single platform installed on carts, connected with an derrick block and including a horizontal ladder with racks installed along its sides and a lifting mechanism that differs in that - dismantling the bridge and increasing its maneuverability, one of the sides of the ramp is connected to the racks by means of hinges, and the lifting mechanism is mounted on shelving 2. A bridge in accordance with claim 1, wherein it is connected to the derrick block by means of hinged tons. 1Shch Fi.Z
