Description

Technical Field

[0001] This utility model relates to the field of derrick transportation, and in particular to an installation component for derrick installation and a derrick towing device. Background Technology

[0002] The transportation of derricks is necessary when moving them from one well to the next, or from the derrick manufacturer to the user. Due to the large overall size of the derrick and its base, they are usually transported separately. This means that the derrick and base need to be easily separated before transportation, and the derrick needs to be installed on the base after transportation.

[0003] When installing the derrick and base, their installation positions need to be aligned. However, when adjusting the alignment of the separated derrick and base, only the position of the transport vehicle can be adjusted. But because the transport vehicle is located on top of the derrick and the derrick is large, even a slight adjustment of the transport vehicle will cause a large positional deviation. As a result, the installation of the derrick on the base requires multiple adjustments, resulting in low installation efficiency. Therefore, a technical solution is needed to solve this technical problem. Utility Model Content

[0004] The purpose of this utility model is to provide an installation component and a derrick towing device for derrick installation, which can adjust the derrick in multiple directions so that the derrick can be quickly aligned with the base, thereby realizing the rapid installation of the derrick.

[0005] The technical solution adopted by this utility model is as follows: a mounting assembly for derrick installation, comprising a front mounting base for supporting the top of the derrick and a rear mounting base for supporting the bottom of the derrick, wherein:

[0006] The front mounting base has a front movable seat and a front drive component that can be fixed to the trailer. The output end of the front drive component is connected to the front movable seat so that the front movable seat can move laterally relative to the trailer.

[0007] The rear mounting base includes a rear lateral movable seat and a rear vertical movable seat. A rear lateral drive component is provided between the rear lateral movable seat and the rear vertical movable seat so that the rear lateral movable seat can move laterally relative to the trailer. A vertical drive support mechanism is connected to the rear vertical movable seat, and the vertical drive support mechanism drives the vertical movable seat to move vertically relative to the trailer.

[0008] Furthermore, the front mounting bracket includes a front fixed bracket for connection with a trailer, a front movable bracket slidably connected to the front fixed bracket, and a front drive component installed between the front fixed bracket and the front movable bracket.

[0009] Furthermore, the rear mounting base also includes a rear fixed base, on which an axle is rotatably connected, and a wheel is connected to the axle; one end of the drive support mechanism is connected to the rear fixed base, and the other end of the drive support mechanism is connected to the rear vertical movable base.

[0010] Furthermore, the drive support mechanism includes a vertical drive member and multiple telescopic mechanisms. The axes of the vertical drive member and the multiple telescopic mechanisms are parallel to each other in pairs, and the two ends of the vertical drive member and the multiple telescopic mechanisms are respectively connected to the rear vertical movable seat and the rear fixed seat.

[0011] Furthermore, the number of telescopic mechanisms is not less than three, and the axis of the vertical drive member intersects the axis of the axle perpendicularly.

[0012] Furthermore, the telescopic mechanism includes a guide cylinder and a guide post, with the guide post and the guide cylinder being slidably connected coaxially.

[0013] Furthermore, the guide cylinder is fixed with multiple wheel seats with rollers, the multiple wheel seats are arranged along the axial direction of the guide cylinder, and the rollers pass through the cylinder wall of the guide cylinder and fit against the surface of the guide column.

[0014] Furthermore, several pads are provided between the wheel seat and the guide cylinder.

[0015] Furthermore, the two ends of the vertical drive member are respectively hinged to the rear vertical movable seat and the rear fixed seat; the two ends of the telescopic mechanism are respectively fixedly connected to the rear vertical movable seat and the rear fixed seat by bolts.

[0016] A derrick trailer includes a trailer and a mounting assembly for mounting the derrick, wherein the front mounting base is mounted on the trailer; and the rear mounting base is mounted on the trailer or serves as an independent structure for supporting the derrick.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] The installation components disclosed in this utility model allow for easy installation of the derrick after it has been transported to its destination. The derrick only needs to be transported by a transport vehicle (trailer) until it is roughly aligned with the base. The position of the derrick can then be adjusted using the front drive component of the front mounting base, the rear lateral drive component of the rear mounting base, and the vertical drive support mechanism. Precise adjustments using the transport vehicle are no longer required. Furthermore, adjustments using the installation components disclosed in this utility model are all localized adjustments to the derrick, making precise adjustments easier and enabling rapid installation of the derrick.

Detailed Implementation

[0026] In the description of this specification, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing this specification and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this specification.

[0027] Furthermore, the use of terms such as "horizontal" or "vertical" in this specification does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0028] In the description of this specification, it should also be noted that, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” should be interpreted broadly. For example, a link can be a fixed link, a detachable link, or an integral link; it can be a mechanical link or an electrical link; it can be a direct link or an indirect link through an intermediate medium; it can be a connection within two components.

[0029] In this manual, "front and back" refers to the axial direction of the derrick, which is also the direction in which the trailer moves forward and backward; "lateral" refers to the direction perpendicular to the derrick's axis and perpendicular to the direction of gravity; and "vertical" refers to the direction parallel to the direction of gravity.

[0030] Example 1

[0031] like Figures 1-5 As shown, a mounting assembly for derrick installation includes a front mounting base 2 for supporting the top of the derrick 3 and a rear mounting base 4 for supporting the bottom of the derrick 3, wherein:

[0032] The front mounting base 2 has a front movable base 22 and a front drive component 23 that can be fixed on the trailer 1. The output end of the front drive component 23 is connected to the front movable base 22 so that the front movable base 22 can move laterally relative to the trailer 1. Specifically, the top of the frame is mounted on the front mounting base 2, and the front movable base 22 is driven to move laterally by the front drive component 23, thereby realizing the lateral movement of the top of the derrick 3. The front movable base 22 has a lug for fixed connection with the derrick 3.

[0033] The rear mounting base 4 includes a rear transverse movable base 41 and a rear vertical movable base 42. A rear transverse drive component 46 is provided between the rear transverse movable base 41 and the rear vertical movable base 42, so that the rear transverse movable base 41 can move laterally relative to the trailer 1. A vertical drive support mechanism 43 is connected to the rear vertical movable base 42, and the vertical drive support mechanism 43 drives the vertical movable base to move vertically relative to the trailer 1. Specifically, the bottom of the derrick 3 is mounted on the rear transverse movable base 41. Since the rear vertical movable base 42 is fixed in the transverse direction relative to the rear transverse movable base 41, the lateral movement of the bottom of the derrick 3 is realized under the action of the rear transverse drive component 46. The rear vertical movable base 42 can move vertically under the action of the vertical drive support mechanism 43, and the rear transverse movable base 41 is slidably connected to the rear vertical movable base 42 to realize the vertical movement of the bottom of the derrick 3. The rear transverse movable base 41 of the rear mounting base 4 has a clamp connecting to the bottom of the derrick 3.

[0034] It should be noted that since the derrick 3 is mounted on the trailer 1, the derrick 3 can move back and forth with the trailer 1. When one end of the derrick 3 is fixed, due to the large axial dimension of the derrick 3, the derrick 3 has deflection along the axis, so the lateral and vertical movement of the other end of the derrick 3 can also be achieved, that is, the derrick 3 can achieve a small range of rotation. Combined with the lateral movement of the top of the derrick 3 and the lateral and vertical movement of the bottom of the derrick 3, the derrick 3 can be effectively adjusted in multiple directions relative to the fixed base, without the need for precise adjustment by the transport vehicle. Furthermore, the adjustment using the installation components disclosed in this utility model is all local adjustment of the derrick 3, making precise adjustment easier, thereby achieving rapid installation of the derrick 3.

[0035] Example 2

[0036] Based on Example 1, further feasible implementation methods are proposed.

[0037] In one feasible implementation, the front mounting base 2 includes a front fixed base 21 for connection with the trailer 1, a front movable base 22 slidably connected to the front fixed base 21, and a front drive member 23 installed between the front fixed base 21 and the front movable base 22.

[0038] Specifically, the front mounting base 21 has a towing pin for connecting with the trailer 1, and the front mounting base 21 is fixedly connected to the trailer 1 through the towing pin.

[0039] In one feasible implementation, the rear mounting base 4 further includes a rear fixed base 44, on which an axle 441 is rotatably connected. A wheel is connected to the axle 441. The rear fixed base 44 can be connected to the trailer 1 or not. The rear fixed base 44 is independently supported at the bottom of the derrick 3. One end of the drive support mechanism is connected to the rear fixed base 44, and the other end of the drive support mechanism is connected to the rear vertical movable base 42. The position of the rear fixed base 44 relative to the ground and the trailer 1 will not change. Therefore, when the drive support mechanism is working, the rear vertical movable base 42 will move vertically.

[0040] Furthermore, the drive support mechanism includes a vertical drive member 45 and multiple telescopic mechanisms. The axes of the vertical drive member 45 and the multiple telescopic mechanisms are parallel to each other and perpendicular to the rear vertical movable seat 42 and the rear fixed seat 44. The two ends of the vertical drive member 45 and the multiple telescopic mechanisms are respectively connected to the rear vertical movable seat 42 and the rear fixed seat 44. The telescopic mechanisms play a guiding role, ensuring that the force applied by the vertical drive member 45 to the rear vertical movable seat 42 and the rear fixed seat 44 is along the direction of gravity, thus avoiding eccentric torque when supporting the rear end of the derrick 3.

[0041] In one feasible implementation, the number of telescopic mechanisms is no less than three, preferably four. Multiple telescopic mechanisms jointly define a support surface, improving the stability of the rear vertical movable seat 42 and the rear fixed seat 44. The axis of the vertical drive member 45 intersects the axis of the axle 441 perpendicularly, so that the force exerted by the vertical drive member 45 on the rear fixed seat 44 is along the axis perpendicular to the axle 441, that is, directly applied to the wheel, avoiding eccentric torque and effectively improving stability.

[0042] Based on the above, the rope rewinding machine 5 can be directly installed on the rear fixed base 44, achieving low-position installation of the rope rewinding machine 5. There is no need to install the rope rewinding machine 5 above the derrick 3, effectively reducing the overall height of the derrick 3 during transportation.

[0043] In one feasible implementation, the telescopic mechanism includes a guide cylinder 432 and a guide post 431, with the guide post 431 and the guide cylinder 432 slidably connected coaxially; the front drive member 23, the rear transverse drive member 46, and the vertical drive member 45 can all be hydraulic cylinders.

[0044] In one feasible implementation, due to machining accuracy constraints, if the guide post 431 and the guide cylinder 432 are slidably connected in a surface-to-surface contact to achieve guidance, high machining and installation accuracy, especially parallelism, is required for the guide post 431 and the guide cylinder 432 when multiple telescopic mechanisms are present, to avoid situations where the entire telescopic mechanism cannot be extended or can only be extended over a short distance. To address this, multiple wheel seats 433 with rollers 434 can be fixed on the guide cylinder 432. The multiple wheel seats 433 are arranged along the axial direction of the guide cylinder 432, and the rollers 434 pass through the cylinder wall of the guide cylinder 432 and fit against the surface of the guide post 431. By having the rollers 434 contact the surface of the guide post 431, the surface-to-surface contact is transformed into a point-to-surface contact, effectively reducing machining and installation accuracy requirements.

[0045] The guide is achieved by the surface of the roller 434 and the guide post 431 being in contact, which makes it less likely for the telescopic mechanism to jam when it extends and retracts simultaneously, thus allowing for a larger stroke.

[0046] Furthermore, a square hole can be made at the position where the wheel seat 433 is installed on the guide cylinder 432 so that the roller 434 can pass through the wall of the guide cylinder 432.

[0047] Furthermore, several pads 435 are provided between the wheel seat 433 and the guide cylinder 432. The number of pads 435 can be adjusted to accurately control the distance between the roller 434 and the surface of the guide post 431.

[0048] In one feasible implementation, the two ends of the vertical drive member 45 are respectively hinged to the rear vertical movable seat 42 and the rear fixed seat 44 to avoid motion interference; the two ends of the telescopic mechanism are respectively fixedly connected to the rear vertical movable seat 42 and the rear fixed seat 44 by bolts, which can be finely adjusted by the gap of the threaded connection in the bolt (usually with a gap of ±1mm), reducing the difficulty of processing and assembly.
