Description
Technical field
This utility model belongs to oil, natural gas drilling mechanical field, the transport erecting device of a kind of drilling platforms preventer.
Background technology
Oil drilling preventer is the key component of well control device, for controlling well head pressure in the operations such as drilling well, well workover, formation testing, it is possible to effectively prevent the generation of gas blowout accident, it is achieved safe construction.Blowout preventer set is typically combined by annular preventer, single ram type perventer, double ram type preventer, four-way and crossover flange, a combination thereof height typically at about 4 ~ 5 meters, weight about 30 tons.Its installation is carried out below rig floor, and ground jack cannot put its effect to good use.In the past, the Normal practice that blowout preventer set is installed is made by hydraulic crane, preventer is first moved to well head by the ways such as puffer etc. lift, artificial passage, then connects in groups piece by piece, this kind of operating type is owing to being limited by rig floor height and working place, centering centering is the most difficult, and operating personnel's labor intensity is big, poor stability, and waste time and energy, and bigger to rig floor and derrick damage ratio.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, the transport erecting device of a kind of drilling platforms preventer, semi-automatic all-hydraulic control are provided, are effectively simplified preventer installation procedure, considerably reduce labor intensity, drastically increase work efficiency and safety.
For realizing above-mentioned technical purpose, the scheme that this utility model provides is: the transport erecting device of a kind of drilling platforms preventer, including flatcar assembly, flatcar track and hydraulic operation device, the loading end of described flatcar assembly is equipped with the connecting bolt for fixing blowout preventer set, the bottom of flatcar assembly is flexibly connected with flatcar track by driving wheel assembly and driven pulley assembly, and driving wheel assembly is by fluid motor-driven；Described flatcar track is connected after aligning with rig substructure well head mark；Described hydraulic operation device is fixed on rig substructure, and hydraulic motor is connected with hydraulic operation device by oil pipeline and hydraulic valve.
And, in the junction of flatcar assembly Yu flatcar track, overturn-preventing hook is installed.
The beneficial effects of the utility model are: 1, semi-automatic all-hydraulic control, and blowout preventer set is fixed on flatcar support after installation becomes integral installation in advance the most piece by piece, effectively simplify preventer installation procedure；2, this device volume is little, low to in-site installation working condition requirement；When 3, using, blowout preventer set is fixed on flatcar, whole Transporting is to well site, then preventer erecting device crane is placed on flatcar track, being run to well head by hydraulic motor along flatcar track by hydraulic operating system, whole process is coherent, succinct, is effectively increased preventer installation effectiveness, reducing labor intensity, safety is greatly improved.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
The present embodiment provides the transport erecting device of a kind of drilling platforms preventer, as shown in Fig. 1 ~ Fig. 4, including flatcar assembly 3, flatcar track 5 and hydraulic operation device 9, the loading end of described flatcar assembly 3 is equipped with the connecting bolt 2 for fixing blowout preventer set 1, the bottom of flatcar assembly 3 is flexibly connected with flatcar track 5 by driving wheel assembly 7 and driven pulley assembly 8, and driving wheel assembly 7 is driven by hydraulic motor 6；Described flatcar track 5 is connected after aligning with rig substructure well head mark；Described hydraulic operation device 9 is fixed on rig substructure, and hydraulic motor 6 is connected with hydraulic operation device 9 by oil pipeline and hydraulic valve.As it is shown in figure 5, be provided with overturn-preventing hook 4 in the junction of flatcar assembly 3 with flatcar track 5.
During use, blowout preventer set 1 being fixed on flatcar assembly 3, preventer erecting device crane, to well site, is then placed on flatcar track 5 by whole Transporting, overturn-preventing hook 4 is installed, is run to well head by hydraulic pressure horse 6 along flatcar track 5 by hydraulic operating system.Above-mentioned everything is completed by the hydraulic operation device 9 being fixed on rig substructure by operator.
The symmetrical uniform design of all steel construction pieces of flatcar assembly 3, carrying is evenly distributed；Stull design bottom flatcar, protects moving parts, prevents because maloperation causes moving parts to touch wellhead assembly；The preventer mounting flange design at flatcar top, is used for fixing blowout preventer, overturn-preventing, is allowed to the stability during movement and safety is greatly improved.
This programme is a kind of all-hydraulic control, semi-automatic preventer erecting device, is effectively simplified preventer installation procedure, reduces labor intensity, improves work efficiency and safety, is particularly suitable for the preventer movement of oil-well rig under all kinds of operating mode.
This programme is not limited only to the movement of preventer, it is possible to extend to the movement of weight bulky, that draw ratio is big.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvement or deformation, these improve or deformation also should be regarded as protection domain of the present utility model.
