Background technique

In recent years, with the continuous development of the world oil market and intensified competition, various oil companies and drilling companies have higher and higher requirements on the time and transportation cost of drilling rigs; major drilling companies at home and abroad have also put forward clear requirements on the moving performance of drilling rigs. Require. It is required that the drilling rig can be moved quickly, so a batch of semi-trailer or trailer drilling rigs (that is, the overall movement of the main unit of the drilling rig or the separate movement of the derrick and the base of the drilling rig) appeared, which largely adapted to the development of the oil market; however, due to The top drive cannot be reliably fixed on the derrick, and the top drive needs to be disassembled each time it is moved. The disassembly of the top drive is completely a high-altitude operation. On the one hand, the disassembly workload is heavy, and on the other hand, there are many safety risks in high-altitude operations.

Contents of the invention

The purpose of this utility model is to provide a fast moving drilling rig top drive and derrick connection and fixing device, which solves the problem that the prior art cannot reliably fix the top drive on the derrick, and the top drive needs to be disassembled every time it is moved, which is time-consuming and laborious. high security risk.

The technical solution adopted by the utility model is a fast-moving drilling rig top drive and derrick connection and fixing device, including top drive guide rail, a section of guide rail at the bottom end of the top drive guide rail is welded with the top drive transport bracket, and fixed on the top drive transport support Clamps for plugging are installed; two sets of connecting devices are installed on the two derrick beams at the lower section of the derrick, each set of connecting devices is fixedly connected with a set of locking devices, and the locking hooks in the locking devices pass through the locking pins Connect with the board.

The fast moving drilling rig top drive and derrick connecting and fixing device of the utility model is also characterized in that each set of locking devices includes a locking support, the locking support is fixed on the derrick beam through a connecting device, and the locking support A top wire is arranged on the outer end surface of the seat, and a connecting plate and a connecting ear plate are welded on the locking support, and the connecting ear plate and the locking hook are connected through a pin shaft.

Each set of connection devices includes four pieces of studs, pressure plates, and lock nuts. The connection plates and pressure plates are respectively pressed against the two facades of the derrick beam, and are connected by four pieces of studs. The two ends of the four pieces of studs are installed With lock nut.

The beneficial effect of the utility model is that the top drive can be fixed on the derrick conveniently and quickly, so that the drilling rig can be moved quickly, the efficiency of drilling rig transportation can be improved, the cost of drilling rig transportation can be reduced, and the utility model is safe and convenient.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Fig. 1, Fig. 2 and Fig. 3, the structure of the fast moving drilling rig top drive and the derrick connecting and fixing device of the present invention is that Fig. 1 shows that the top drive is at the lowest position of the derrick, and the top drive guide rail is vertically arranged in the derrick 17 16. The top drive guide rail 16 is slidingly connected to the top drive 19, the top drive 19 is hooked and connected to the traveling car 18, the lowermost section of the top drive guide rail 16 is welded to the top drive transport bracket 1, and the top drive transport bracket 1 is fixedly installed with The clamping plate 2 for plugging is shown in Fig. 4; two sets of connecting devices 4 are arranged on the two derrick beams 15 of the lower section of the derrick, and each set of connecting devices 4 is fixedly connected with a set of locking devices 3. Locking device 3 and connecting device 4 are established in 4-6 groups according to specific site conditions.

Referring to Fig. 5, each group of locking devices 3 includes a locking support 5, the locking support 5 is fixed on the derrick beam 15 through a connecting device 4, and the outer end surface of the locking support 5 is provided with a top wire 6, The connecting plate 9 and the connecting ear plate 7 are welded on the locking support 5.
