Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for drilling rigs on drill and blast vessels, and particularly relates to a positioning device for a drilling rig on a drill and blast vessel. Background Art

[0002] Generally, the drilling rig on a waterborne drill and blast vessel is fixed by means of clamping, embedding and gravity. Specifically, it is fixed in a fixture through a column, and then fixed on both sides of the ship deck by means of splints, clamping grooves, etc. After the drilling rig drills a hole, when drilling the next hole, it is necessary to disassemble the original drilling rig and install the drilling rig at the new drilling position. This process takes a long time and the drilling efficiency is relatively low. In the prior art, rollers can be arranged at the bottom of the drilling rig, and tracks corresponding to the rollers are installed on the deck. The rollers can roll on the tracks, so as to facilitate the position adjustment of the drilling rig. After the position adjustment is completed, the drilling rig can be fixed by means of pin shafts, roller brakes, etc. to drill the next hole, which improves the overall drilling efficiency. However, in the actual process, the drilling rig is large in volume and weight, and has a great impact on the vibration of the drill and blast vessel when moving on the track, and it is easy to cause the ship deck to be damaged acceleratedly. Summary of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the utility model provides a positioning device for a drilling rig on a drill and blast vessel, which solves the problem that the ship deck may be damaged acceleratedly due to vibration during the movement of the drilling rig in the prior art.

[0004] According to an embodiment of the utility model, a positioning device for a drilling rig on a drill and blast vessel includes a pair of crossties laid horizontally and oppositely on the deck of the drill and blast vessel, and a pair of tracks respectively arranged on the two crossties. The tracks are connected to the corresponding crossties through elastic connectors; limit blocks fixedly connected to the corresponding crossties are further arranged at both ends of the tracks. The limit blocks include a pair of vertically installed arms and a limit arm fixedly connected to the two vertically installed arms. The two vertically installed arms and the limit arm enclose a U-shaped structure buckled above the track.

[0005] In the above embodiment, the arranged tracks are for the rollers of the drilling rig to roll, so as to facilitate the position adjustment of the drilling rig. In this solution, crossties are also arranged to isolate between the deck and the tracks, and the tracks and the crossties are connected through elastic connectors. The vibration generated by the tracks can be weakened by the elastic connectors and then act on the crossties, thereby reducing the influence on the deck and solving the problem that the ship deck may be damaged acceleratedly due to vibration during the movement of the drilling rig in the prior art.

[0006] Furthermore, a connecting block is fixedly connected to one end of the vertically installed arm背离 the limit arm, and the connecting block is fixedly connected to the crosstie through a connecting rod.

[0007] Further, the two connecting blocks on the same limiting block are both located inside the U-shaped part, or both located outside the U-shaped part, or one is located inside the U-shaped part and the other is located outside the U-shaped part.

[0008] Further, the track includes a main body and wing plates fixedly connected to both sides of the main body, and the elastic connecting member includes a plurality of members respectively connected to the two wing plates.

[0009] Further, the elastic connecting member includes a pressing plate and a supporting plate located above and below one of the wing plates, an installation shaft connecting the pressing plate and the supporting plate, and a spring sleeved on the installation shaft and located between the supporting plate and the sleeper. Both ends of the installation shaft are threadedly connected to the pressing plate and the sleeper respectively, and the installation shaft passes through the supporting plate vertically.

[0010] Further, a crosstie is also clamped between the sleeper and the track.

[0011] Further, a connecting beam is fixedly connected between the two sleepers.

[0012] Further, reinforcing plates are fixedly connected between the two sleepers and located at both side ends of the connecting beam.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] By arranging the sleeper to be isolated between the deck and the track, and the track and the sleeper are connected by an elastic connecting member, the vibration generated by the track can be weakened by the elastic connecting member and then act on the sleeper, thereby reducing the influence on the deck and solving the problem that the ship deck may be accelerated and damaged due to vibration during the movement of the drill rig in the prior art.

Specific embodiments

[0022] The technical solutions in the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0024] In an exemplary embodiment, as Figure 1-5 shown, this embodiment provides a positioning device for a drill rig on a drill and blast ship, which includes a pair of sleepers 1 laid horizontally and oppositely on the deck of the drill and blast ship, and a pair of tracks 2 respectively arranged on the two sleepers 1. The tracks 2 are connected to the corresponding sleepers 1 through elastic connecting pieces 3; limit blocks 4 fixedly connected to the corresponding sleepers 1 are also arranged at both ends of the tracks 2. The limit blocks 4 include a pair of vertical installation arms 5 and a limit arm 6 fixedly connected to the two vertical installation arms 5. The two vertical installation arms 5 and the limit arm 6 enclose a U-shaped shape buckled above the track 2. The sleepers 1 and the tracks 2 are both made of steel materials. The limit blocks 4 play a role in limiting the operation of the drill rig at both ends of the track 2. When the roller contacts one of the pairs of limit blocks 4, it can no longer move, preventing the drill rig from derailing.

[0025] In the above embodiments, the provided track 2 allows the rollers of the drilling rig to roll, facilitating the position adjustment of the drilling rig. In this solution, a sleeper 1 is also provided, which is isolated between the deck and the track 2, and the track 2 and the sleeper 1 are connected by an elastic connecting member 3. The vibration generated by the track 2 can be weakened by the elastic connecting member 3, further weakened after being transmitted to the sleeper 1, and then acting on the sleeper 1, thereby reducing the impact on the deck and solving the problem in the prior art that the ship deck may be accelerated and damaged due to vibration during the movement of the drilling rig. Specifically, in a detailed solution, the track 2 includes a body 7 and wing plates 8 fixedly connected to both sides of the body 7. The elastic connecting member 3 includes a plurality of elastic connecting members respectively connected to the two wing plates 8. The elastic connecting member 3 provides elastic support for a track 2 on both sides together, thereby improving the running stability of the track 2. More specifically, the elastic connecting member 3 includes a pressing plate 9 and a supporting plate 10 located above and below one of the wing plates 8, an installation shaft 11 connecting the pressing plate 9 and the supporting plate 10, and a spring 12 sleeved on the installation shaft 11 and located between the supporting plate 10 and the sleeper 1. Both ends of the installation shaft 11 are threadedly connected to the pressing plate 9 and the sleeper 1 respectively, and the installation shaft 11 passes through the supporting plate 10 up and down. When the drilling rig moves, the supporting plate 10 can move up and down on the installation shaft 11. The vibration of the track 2 causes the lower supporting plate 10 to vibrate accordingly, so that the spring 12 expands and contracts, absorbing the vibration impact. Further, the remaining vibration will continue to be transmitted to the sleeper 1 instead of directly acting on the deck, thus having a smaller impact on the deck. In a more specific solution, the sleeper 1 and the deck can be connected by bolts to achieve fixation.

[0026] As Figure 1-5 shown, in a further exemplary solution, a sleeper beam 13 is also clamped between the sleeper 1 and the track 2. The sleeper beam 13 is made of wood and can assist the spring 12 to cooperate in weakening the vibration, thereby further reducing the impact of the vibration on the deck.

[0027] As Figure 1-5 shown, in a further exemplary solution, a connecting block 14 is also fixedly connected to the end of the vertical mounting arm 5 away from the limiting arm 6. The connecting block 14 is fixedly connected to the sleeper 1 through a connecting rod 15. The connecting block 14 and the connecting rod 15 realize the connection between the limiting block 4 and the sleeper 1. The provided connecting rod 15 can be a screw rod, which facilitates the disassembly of the limiting block 4. In a more detailed solution, the two connecting blocks 14 on the same limiting block 4 are both located inside the U-shaped, or both located outside the U-shaped, or one is located inside the U-shaped and the other is located outside the U-shaped. These setting methods of the connecting blocks 14 are all acceptable. Among them, setting the two connecting blocks 14 both inside the U-shaped can not occupy external space, and there is a large space between the bottom surface of the limiting arm 6 and the top surface of the connecting block 14 to facilitate the installation operation of the connecting rod 15.

[0028] As Figure 1-5As shown, in a further exemplary embodiment, a connecting beam 16 is fixedly connected between the two sleepers 1, and the connection amount and the sleeper 1 are an integrated structure, so that the two sleepers 1 are an integral structure with better structural strength. A reinforcing plate 17 located at both side ends of the connecting beam 16 is also fixedly connected between the two sleepers 1. This arrangement improves the overall structural strength of the sleeper 1, thereby making the overall positioning device more stable.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
