Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of oil drilling rigs and workover rigs, and relates to a whole derrick moving device, and also relates to a method for moving a whole derrick by using the device. BACKGROUND

[0002] When the conventional derrick moving device is used to move a derrick, the alignment of the derrick lower support feet and the bottom base support feet double ear seats is usually performed according to the following method:

[0003] 1. The alignment of the derrick lower support feet and the bottom base support feet double ear seats in the left-right direction is performed by pushing the derrick support beam in the left-right direction through the horizontal direction hydraulic oil cylinder arranged on the derrick moving device, so that the derrick support beam and the derrick as a whole move relative to the bottom base support feet double ear seats in the left-right direction.

[0004] 2. The alignment of the derrick lower support feet and the bottom base support feet double ear seats in the up-down direction is performed by pushing the derrick support beam in the up-down direction through the vertical direction hydraulic oil cylinder arranged on the derrick moving device, so that the derrick support beam and the derrick as a whole move relative to the support feet in the up-down direction.

[0005] 3. The alignment of the derrick lower support feet and the bottom base support feet double ear seats in the front-rear direction is performed by pulling the derrick moving device in the front-rear direction through the tractor located below the derrick crown block, so that the derrick moving device and the derrick as a whole move relative to the support feet in the front-rear direction.

[0006] The conventional derrick moving device and the alignment method thereof have the following disadvantages:

[0007] 1. There are too many adjusting oil cylinders, and the adjusting and control operation is complicated.

[0008] 2. The alignment of the derrick lower support feet and the bottom base support feet double ear seats in the front-rear direction is performed by pulling the derrick moving device through the tractor, and this method has the limitation that, because the distance between the bottom base and the bottom base support feet double ear seats on the derrick moving device route is large, the distance between the derrick rear support feet and the derrick moving device is too large, the derrick rear cantilever relative to the derrick moving device is too long, the stress state is not good, and in addition, the load distribution of the derrick moving device and the tractor is also restricted.

[0009] In addition, when the conventional derrick moving device is not equipped with the adjusting and centering oil cylinder, the derrick lower support feet are hoisted as a whole through the crane, the derrick lower support feet are aligned with the bottom base support feet ear plate hole center through the crane, and the pin shaft is installed.

The hydraulic cylinder 6 is inclinedly mounted on the trailer frame 3, and the cylinder body of the hydraulic cylinder 6 is fixed to the trailer frame 3. The piston rod of the hydraulic cylinder 6 is hinged to the other end of the derrick support frame 8.

[0044] The two ends of the derrick support frame 8 are respectively provided with two front derrick fixing ears 12 and two rear derrick fixing ears 10; the two front derrick fixing ears 12 are respectively located on opposite sides of one end of the trailer frame 3, and the two rear derrick fixing ears 10 are respectively located on opposite sides of the other end of the trailer frame 3.

[0045] The trailer frame 3 has two sets of wheel assemblies 7 at its bottom, located on opposite sides of the bottom of the trailer frame 3. The two sets of wheel assemblies 7 are situated between two sets of positioning bases 9, which are connected to opposite sides of the drilling rig base base 17 via connecting brackets 13. The trailer adjustable support leg 5 is located on the side of the trailer frame 3 closest to the trailer towing pin 4.

[0046] This invention discloses a method for moving a derrick using an integrated derrick moving device (installation and positioning process of derrick 14 onto drilling rig 16), such as... Figures 4-8 As shown, the specific steps include the following:

[0047] Step 1: The tractor unit 1 reverses, pushing the derrick trailer assembly onto the positioning base 9, and lowers the adjustable support legs 5 of the trailer to contact the ground. Step 1 is from... Figures 4-5 The process of proceeding;

[0048] Step 2: Remove the connecting pins between the derrick 14 and the rear fixing lug 10 and the front fixing lug 12 of the derrick;

[0049] Step 3: Start the hydraulic cylinder 6, so that the piston rod of the hydraulic cylinder 6 extends and pushes one end of the derrick support frame 8 to rotate relative to the pin at the hinge of the derrick support frame 8 and the trailer frame 3. The other end of the derrick support frame 8 rises, and the roller 11 on the derrick support frame 8 rises accordingly; as shown in Figure 6.

[0050] Step 4: The tractor 1 reverses and pushes the derrick 14, which in turn pushes the roller 11 to rotate, thereby moving the rear support leg 15 of the derrick closer to the installation position of the rear support leg on the upper seat 16 of the drilling rig base. Figures 4-8 Move in the direction of position A (where the rear support leg of the derrick is installed);Figure 7 for the well derrick rear support mounting position A and the well derrick rear support 15 just butt joint state;
