Fig. 1 is a schematic view of a straight-pushing catwalk device 100 according to the present utility model in a lowered state.
As shown in fig. 1, according to a first aspect of the present utility model, there is provided a direct push catwalk apparatus 100 including a first conveying mechanism 1. The first conveyor 1 comprises a first carriage 11, a second carriage 12 and a first drive 13. The first carriage 11 is a main body structure of the straight-pushing catwalk device 100, so that the second carriage 12 can be effectively supported. The second carriage 12 is provided inside the first carriage 11 so as to function as a housing and support for a pipe string (not shown in the drawings). The first driving member 13 is disposed on the second carriage 12 so as to be capable of driving the tubular string to move axially on the second carriage 12, thereby facilitating subsequent tubular string conveying operations.
Preferably, the fixed end of the second carriage 12 is hinged to the first end of the first carriage 11. The free end of the second carriage 12 can thus be lifted by the first piston element 4 (described below) and can be brought into abutment with the flap 31 (described below), so that the purpose of transporting the tubular string is achieved under the cooperation of the second carriage 12 and the first drive element 13. The contents of which are described below.
According to the present utility model, as shown in fig. 1, the direct-push catwalk apparatus 100 further includes a second conveying mechanism 2. The second conveyor 2 comprises a ramp frame 21 and a flap assembly 3. Wherein the ramp frame 21 is hinged to a first end of the first carriage 11 and the flap assembly 3 is mounted on the ramp frame 21. Preferably, the ramp 21 is angled with respect to the first carriage 11 to ensure that the second drive 32 (described below) is able to smoothly interface with the first drive 13 when the second carriage 12 interfaces with the flap 31, thereby facilitating transport of a tubular string onto the flap 31 (described below) of the flap assembly 3.
Fig. 3 shows the structure of the direct-push catwalk device 100 according to the present utility model, in which the flap 31 is in a tilted state.
In one embodiment, as shown in fig. 3, the flap assembly 3 includes a flap 31 disposed on the ramp frame 21. Preferably, the flap 31 is hinged to the end of the ramp frame 21 remote from the first carriage 11, so that the flap 31 can be more easily rotated with the hinged end as the origin, thereby enabling the flap 31 to have the ability to convey the pipe string in the forward direction or in the reverse direction.
In one embodiment, as shown in fig. 3, the flap assembly 3 includes a second drive 32. The second driving member 32 is disposed on the turning plate 31, and the second driving member 32 on the turning plate 31 and the first driving member 13 on the second carriage 12 can be effectively matched to achieve the purpose of conveying the pipe column when the second carriage 12 is in butt joint with the turning plate 31. The contents of which are described below.
Fig. 2 is a schematic diagram of the lifted state of the straight-pushing catwalk device 100 according to the present utility model.
According to the utility model, as shown in fig. 1 and 2, the direct-push catwalk device 100 further comprises a first piston element 4 connecting the second carriage 12 with the flap 31. The first piston member 4 is configured to enable the second carriage 12 to interface with the flap 31 or to enable the second carriage 12 to be reset into the first carriage 11 for subsequent pipe string transport operations. In this way, the push-through catwalk device 100 is enabled with good flexibility and operability.
According to the present utility model, the direct push catwalk apparatus 100 further includes a controller (not shown) in communication with the first and second driving members 13 and 32, respectively. Therefore, the straight-pushing catwalk device 100 can control the position of the first driving element 13 on the second conveying frame 12 and the position of the second driving element 32 on the turning plate 31 respectively through the controller, so as to achieve the purpose of conveying the pipe column, and therefore, the pipe column conveying efficiency and the safety of the straight-pushing catwalk device 100 are obviously improved.

Fig. 4 is a top view of a push-through catwalk apparatus 100 according to the present utility model. Fig. 6 is a schematic structural view of the lifting assembly 5 in the direct-push catwalk apparatus 100 according to the present utility model
According to the utility model, as shown in fig. 4 and 5, the first conveyor 1 further comprises a lifting assembly 5. The lifting assembly 5 comprises a fixed square steel 51, a second piston member 52 and a rolling member 53. Wherein the fixed square steel 51 is mounted on the second carriage 12 so as to effectively support the overall structure of the lifting assembly 5. The second piston member 52 is disposed in the fixed square steel 51 and fixedly connected with the rolling member 53, thereby enabling the lifting of the column portion. Preferably, the rolling member 53 is fixedly coupled to the top end of the second piston member 52 by a bracket 54 to allow the passage of the tubular string to facilitate subsequent delivery operations.
According to one embodiment of the utility model, the second piston element 52 is configured to cause the rolling element 53 to move in a vertical direction so as to tilt the tubular string and partially rest against the flap 31. Specifically, the second piston member 52 is movable in the vertical direction, thereby causing the front end of the pipe string to tilt up. In this way, the front end of the pipe string can first contact the flap 31 under the pushing action of the first driving member 13, and the pipe string can gradually and completely abut against the flap 31 under the continuous pushing action of the first driving member 13.
In one embodiment, as shown in fig. 4, the first conveyor 1 further comprises a pair of tube turnover members 6. Both of the pipe turners 6 are provided on the second carriage 12, and the pipe turners 6 are configured to be movable in the vertical direction to bring the pipe string into engagement with the first driver 13. In particular, the pipe turning member 6 is movable in a vertical direction to thereby cause lifting of the pipe string in whole or in part, whereby a stable connection is established between the first driving member 13 and the pipe string.
In a particular embodiment, two flaps 6 are provided on either side of the second carriage 12, respectively, so as to enable selective lifting of the tubular string. For example, only one of the pipe turning pieces 6 can be controlled to lift one side of the pipe column, and two pipe turning pieces 6 can be simultaneously controlled to lift the whole pipe column.
In a preferred embodiment, the flap member 6 is closer to the fixed end of the second carriage 12 than the lifting assembly 5. Therefore, the catwalk device 100 can lift the whole or part of the pipe column through the pipe turning piece 6, so as to promote the first driving piece 13 to form a stable connection relationship with the pipe column; the front end of the pipe column is tilted up by the second piston member 52, so that the pipe column is gradually and completely abutted against the turning plate 31 under the pushing action of the first driving member 13.
In one embodiment, the flap 31 is hinged to the end of the ramp frame 21 remote from the first carriage 11. Accordingly, the flap 31 is configured to be rotatable with the hinged end as an origin, so that the pipe string can be more easily transported to a position suitable for hanging an elevator or received and reset onto the ramp frame 21.
In one embodiment, during forward transport of the pipe string (the direction of movement of the pipe string is from the second carriage 12 to the flap 31), the controller is configured to control the movement of the first driver 13 to the point where the second carriage 12 interfaces with the flap 31 to urge the pipe string fully against the flap 31 to transport the pipe string to the outside via the second driver 32.
According to one embodiment of the present utility model, first, the whole or part of the string is lifted by turning the pipe member 6, so that a stable connection relationship is formed between the string and the first driving member 13. The second carriage 12 is then controlled by the first piston member 4 to interface with the flap 31. The front end of the pipe string is then raised by the second piston member 52 of the lifting assembly 5, and the first drive member 13 is then moved to the interface of the second carriage 12 and the flap 31.
The tubular string can thus gradually come to rest completely against the flap 31 under the pushing action of the first piston element 4. Thereafter, the second driver 32 interfaces with the first driver 31 such that a stable connection is established between the tubular string and the second driver 32. Thereafter, the flap 31 rotates with the hinge end as the origin. Thus, the second drive 32 is able to transport the tubular string to a position suitable for hanging an elevator, thereby effecting forward (up) transport of the tubular string.
In one embodiment, upon reverse conveyance of the pipe string (the direction of movement of the pipe string is from the flap 31 to the second carriage 12), the controller is configured to control the second drive 32 to move to the point where the flap 31 interfaces with the second carriage 12, thereby receiving the pipe string via the first drive 13 and transporting the pipe string to a position fully against the second carriage 12.
According to one embodiment of the utility model, first, the flap 31 is tilted and receives the pipe string. At this time, a stable connection is formed between the rear end of the pipe string and the second driver 32 (a specific process is described below). The flap 31 is then controlled by the first piston element 4 to interface with the second carriage 12. Thereafter, the flap 31 is reset, and then the second driving member 32 moves to the junction of the flap 31 and the second carriage 12. The first drive member 13 then interfaces with the second drive member 32 and the tubular string is moved by the drive of the first drive member 13 progressively fully against the second carrier 12. Finally, the return of the second carriage 12 into the first carriage 11 is controlled by the first piston member 4, so that the reverse (downward) transport of the pipe string is achieved.
At present, the catwalk device in the prior art generally realizes the purpose of conveying by fully lifting the pipe tool, so that the device has quite high power requirement and can cause a great deal of power loss in the lifting process, thereby increasing the cost of construction operation.
In contrast to the prior art described above, the present utility model requires only lifting the free end of the second carriage 12 by the first piston member 4, thereby facilitating an effective docking of the second carriage 12 with the flap 31. The tubular string is thereby able to perform forward/reverse conveyance by the combined action of the first and second drive members 13, 32. In this way, the power loss of the direct-push catwalk device 100 is effectively reduced, and the cost of construction operation is further reduced. In addition, the first driving piece 13 and the second driving piece 32 can be remotely controlled by the controller, so that automatic conveying of the pipe column is realized, and further, the working efficiency of the direct-pushing catwalk device 100 is effectively improved.
Fig. 5 is a schematic structural view of the turning pipe member 6 in the straight-pushing catwalk device 100 according to the present utility model.
According to the utility model, as shown in fig. 5, the tube-turning piece 6 comprises a guide frame 61, a lifting plate 63 and a third piston piece 62. The guide frame 61 is provided on the second carriage 12. The lifting plate 63 is installed at the top end of the guide frame 61 and can effectively support the pipe string. The third piston member 62 is disposed in the guide frame 61, and the top end of the third piston member 62 is fixedly connected to the lifting plate 63.
According to one embodiment of the utility model, the third piston member 62 is configured to move the lifting plate 63 in a vertical direction to bring the pipe string into engagement with the first drive member 13 as the pipe string is being conveyed.
In one embodiment, as shown in FIG. 5, the lift plate 63 includes a first lift plate portion 631 configured as a V-shape, and a second lift plate portion 632 in the form of a flat plate extending radially outward from both sides of the first lift plate portion 631. In this way, the pipe string can be more fully attached to the first lifting plate portion 631 during the conveying process, so as to ensure the safety of the pipe string during the conveying process.
In one embodiment, the direct push catwalk apparatus 100 includes protective screens (not shown in the drawings) disposed on both sides of the ramp frame 21. The protection net is fixedly connected with the second lifting plate portion 632, so that the radial position of the pipe string can be effectively limited. Therefore, the safety coefficient of the pipe column in the conveying process is improved, and the straight-pushing catwalk device 100 meets the requirement of safe production operation more easily.
In one embodiment, the ramp frame 21 forms a 50 ° angle with the first carriage 11. The second carriage 12 forms an angle of 0 to 13 with the first carriage 11. Thus, the tubular string is made easier to move on the second carriage 12 by the first drive 13 and on the flap 31 by the second drive 32. Compared with the prior art, the utility model obviously reduces the power requirement and loss. In addition, the utility model also reduces the cost of construction operation and improves the working efficiency of pipe column conveying.
In one embodiment, as shown in fig. 4, the direct push catwalk device further comprises a pick-up finger 7. Wherein, the pick-up claw 7 is arranged at the top end of the first conveying frame 11, thereby being capable of effectively limiting the horizontal position of the pipe column by matching with the first conveying frame 11. Therefore, the pipe column can be well protected during forward/reverse conveying, so that the safety of the pipe column in the conveying process is effectively improved, and the possibility of dangerous accidents is further reduced.
In one embodiment, as shown in fig. 4, the direct push catwalk device further comprises a base leg 8. The base leg 8 is provided at the bottom end of the first carriage 11. It will be readily appreciated that the base legs 8 carry the weight of the entire push catwalk apparatus 100, thereby ensuring the stability of the apparatus as a whole when the pipe string is being conveyed in both forward and reverse directions.
According to a second aspect of the present utility model there is provided a method of transporting a tubular string using a straight push catwalk apparatus as described above, comprising at least one of a forward transport step and a reverse transport step.
The forward conveying step and the reverse conveying step are described below, respectively.
The forward conveying step comprises the following steps:
first, the pipe string is placed on the second carriage 12 and lifted in whole or in part by the pipe turning member 6, so that a stable connection relationship with the first driving member 13 can be formed.
Then, the second carriage 12 is docked with the flap 31 by the first piston member 4;
the tubular string is then partially brought into abutment against the flap 31 by lifting the assembly 5 and the first drive 13; the first driving piece 13 is controlled by the controller to move to the joint of the second conveying frame 12 and the turning plate 31 so that the pipe column is completely abutted on the turning plate 31.
Specifically, the front end of the pipe string is raised by the second piston member 52 of the lifting assembly 5, and then the first driving member 13 moves to the junction of the second carriage 12 and the flap 31. The tubular string can thus gradually come to rest completely against the flap 31 under the pushing action of the first piston element 4.
Then, the controller controls the second driving member 32 to interface with the first driving member 13, so that a stable connection relationship is formed between the pipe string and the second driving member 32.
Finally, the string is transported to the outside by the second driving member 32.
Specifically, the flap 31 rotates with the hinge end as the origin. Thus, the second drive 32 is able to transport the tubular string to a position suitable for hanging an elevator, thereby effecting forward (up) transport of the tubular string.
The reverse conveying step comprises the following steps:
first, the flap 31 is tilted to receive the pipe string, and is tilted by the lift plate 63 to form a stable connection relationship between the second driving piece 32 and the pipe string.
The second carriage 12 is then docked with the flap 31 by the first piston element 4.
Thereafter, the flap 31 is reset, and then the second driving member 32 moves to the junction of the flap 31 and the second carriage 12.
Then, the controller controls the first driving member 13 and the second driving member 32 to be connected, so that a stable connection relationship is formed between the first driving member 13 and the tubular column.
The tubular string is then moved by the drive of the first drive member 13 gradually and completely against the second carriage 12.
Finally, the return of the second carriage 12 into the first carriage 11 is controlled by the first piston member 4, so that the reverse (downward) transport of the pipe string is achieved.
The utility model provides a direct-pushing catwalk device 100, which can be used for butting a second conveying frame 12 with a turning plate 31 through a first piston member 4 and controlling a first driving member 13 and a second driving member 32 to convey a pipe column on the second conveying frame 12 or the turning plate 31 through a controller. By the mode, the power requirement on the whole device is reduced, and the power loss in the process of conveying the pipe column is obviously reduced, so that the cost of construction operation is effectively reduced. In addition, the automatic conveying device can realize automatic conveying of the pipe column, so that direct contact with the pipe column is effectively avoided, and labor output cost is reduced. In addition, the utility model not only has an effective limiting effect on the pipe column moving on the second conveying frame 12 through the pick-up claw 7, but also has an effective limiting effect on the pipe column moving on the turning plate 31 through the turning plate 31 and the protective net, so that the safety of the pipe column in forward/reverse conveying can be effectively ensured.
The above is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto. Modifications and variations may readily be made by those skilled in the art within the scope of the present disclosure, and such modifications and variations are intended to be included within the scope of the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
