Description

Technical Field

[0001] The utility model relates to the technical field of traveling block hoisting, in particular to a hoisting bar device for hoisting a traveling block. Background Art

[0002] During oil rig relocation operations, the traveling block, a key component of the traveling system, needs to be disassembled and hoisted horizontally for easy handling. Because the traveling block has only a shackle at one end and no lifting points, the existing conventional lifting method typically involves attaching the shackle at that end and securing it with a wire rope through a hole in the lifting plate. However, due to the sharp corners of the lifting plate, this lifting method can easily damage or break the wire rope sleeve during assembly and disassembly, causing lifting accidents, personal injury, or equipment damage. Furthermore, this lifting method makes it difficult to achieve a smooth lifting operation, increasing the risk of rollover.

[0003] The existing traveling block hoisting method has a technical problem that the wire rope sleeve directly contacts the corners of the hoisting plate during hoisting, causing damage, thereby bringing the risk of personal injury or equipment damage, and is prone to overturning. Utility Model Content

[0004] The purpose of the utility model is to provide a lifting lever device for lifting a traveling carriage, so as to solve the technical problem in the related art that the wire rope loop is damaged by direct contact with the sharp corners of the lifting plate during lifting, thereby bringing the risk of personal injury or equipment damage and easy rollover.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is:

[0006] The utility model provides a lifting bar device for lifting a traveling carriage, comprising:

[0007] The lifting beam, lifting lugs, and lifting bar shackles are mounted on the traveling block. The two lifting lugs are connected to the lifting bar shackles and are located at both ends of the lifting beam. The two lifting bar shackles and the main shackle form a triangle when projected horizontally, and are used to connect to the wire rope loop.

[0008] Specifically, the hoisting beam includes a middle beam and two suspension beams respectively provided at both ends of the middle beam. The middle beam is inserted into the bail pin hole formed by the hook seat and the bail. The two hoisting lugs are respectively provided at one end of the suspension beam away from the middle beam.

[0009] Specifically, the suspension beam is arranged to be tilted upward along the middle beam toward the hoisting lug plate. Under the action of gravity, the traveling carriage slides along the suspension beam and is centered in the length direction of the hoisting beam.

[0010] Specifically, it further comprises a fixed clamping plate, wherein two fixed clamping plates are sleeved on the hoisting beam at intervals and respectively abut against both sides of the traveling carriage along the length direction of the hoisting beam.

[0011] Specifically, the fixed clamping plate is arranged at the junction of the middle beam and the suspension beam.

[0012] Specifically, the fixed clamping plate is provided with a first acting surface, and two first acting surfaces are respectively in contact with two sides of the hook seat along the length direction of the lifting beam.

[0013] Specifically, the fixed clamping plate is further provided with a second action surface, and the second action surface abuts against the side baffle of the traveling carriage.

[0014] Specifically, the lifting bar shackle includes a shackle body and a pin shaft, wherein the shackle body is provided with an eyelet, the lifting lug plate is provided with a lifting hole, and the pin shaft is simultaneously inserted into the eyelet and the lifting hole.

[0015] Specifically, the lifting beam, the lifting ear plate and the fixing clamping plate are welded into one body.

[0020] In practical application, the hoisting beam is placed across the traveling block, and the lifting bar shackles are installed on the two lifting lugs. The wire rope loops are connected to the two lifting bar shackles and the main shackle to hoist the traveling block. The horizontal projections of the two lifting bar shackles and the main shackle form a triangle, ensuring stable hoisting of the traveling block.

[0021] It can be seen that compared with the existing technology, the lifting arm device for lifting the traveling carriage avoids direct contact between the traveling carriage and the wire rope sleeve by being inserted into the lifting beam of the traveling carriage and the lifting ear plates at both ends of the lifting beam, thereby realizing triangular three-point lifting of the traveling carriage, overcoming the technical problems of the existing traveling carriage lifting method that the wire rope sleeve is damaged due to direct contact with the sharp corners of the lifting plate during lifting, thereby bringing risks of personal injury or equipment damage and easy rollover.

[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0034] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0035] The existing traveling block hoisting method has a technical problem that the wire rope sleeve directly contacts the corners of the hoisting plate during hoisting, causing damage, thereby bringing the risk of personal injury or equipment damage, and is prone to overturning.

[0036] In view of this, the present invention provides a lifting bar device for lifting a traveling carriage, comprising:

[0037] The lifting beam 100, lifting lugs 200, and lifting bar shackles 300 are mounted on the traveling block 010. Two lifting lugs 200 are connected to lifting bar shackles 300 and are located at each end of the lifting beam 100. The two lifting bar shackles 300 and the main shackle 001 form a triangle when projected horizontally, and are used to connect to the wire rope loop.

[0038] In summary, the lifting bar device for lifting a traveling carriage provided by the present invention can achieve the following technical effects:

[0039] This lifting bar device for lifting a traveling carriage avoids direct contact between the traveling carriage 010 and the wire rope loops by inserting the lifting beam 100 of the traveling carriage 010 and the lifting lugs 200 at both ends of the lifting beam 100, thereby achieving a triangular three-point lifting of the traveling carriage 010. This overcomes the technical problems of existing traveling carriage lifting methods, such as the wire rope loops being damaged by direct contact with the sharp corners of the lifting plate during lifting, which can cause personal injury or equipment damage, and can also easily cause overturning.

[0040] The following combination Figures 1 to 3 The structure and shape of the lifting lever device for lifting the traveling carriage provided in this embodiment are described in detail:

[0041] Regarding the structural composition of the traveling block 010, specifically:

[0042] Traveling block 010 includes a main shackle 001, a hook base 002, a bail 003, and side guards 005. The main shackle 001 and hook base 002 are mounted at either end of the traveling block 010, with both ends of the bail 003 connected to the hook base 002 by pins. The hook base 002 and bail 003 form a bail pin hole 004, which is used to suspend the top drive drilling rig for drilling operations.

[0043] Regarding the structural composition of the lifting beam 100, specifically:

[0044] The lifting beam 100 comprises a center beam 110 and two suspension beams 120, one at each end of the center beam 110. The center beam 110 is inserted into the bail pin hole 004 formed by the hook seat 002 and the bail 003. Two lifting lugs 200 are respectively provided at the end of the suspension beam 120 away from the center beam 110. The contact between the center beam 110 and the hook seat 002 provides support for the end of the traveling block 010 away from the main shackle 001. The connection between the suspension beam 120 and the lifting lugs 200 can be welded.

[0045] In the solution of this embodiment, the lifting beam 100 can be set as a hollow circular tube or a hollow square tube.

[0046] To center the traveling carriage 010 along the length of the hoisting beam 100 and reduce the deflection caused by the shift in the center of gravity of the traveling carriage 010, in this embodiment, the suspension beam 120 is arranged along the intermediate beam 110 toward the hoisting lug 200, with the hoisting lug 200 extending away from the suspension beam 120. Under the action of gravity, the traveling carriage 010 slides along the suspension beam 120 and centers itself along the length of the hoisting beam 100, thereby eliminating the shift in the center of gravity of the traveling carriage 010.

[0047] In order to further enhance the positioning effect of the traveling carriage 010 in the length direction of the lifting beam 100, in the solution of this embodiment, the lifting bar device also includes a fixed clamping plate 400, and the two fixed clamping plates 400 are spaced apart and sleeved on the lifting beam 100, and respectively abut against the two sides of the traveling carriage 010 along the length direction of the lifting beam 100 to limit the axial position of the traveling carriage 010.

[0048] In the solution of this embodiment, the lifting bar shackle 300 includes a buckle body 310 and a pin 320, the buckle body 310 is provided with an eye 301; the lifting ear plate 200 is provided with a lifting hole 201; the pin 320 is inserted into the eye 301 and the lifting hole 201 at the same time.

[0049] In the solution of this embodiment, the fixed clamping plate 400 is arranged at the junction of the middle beam 110 and the suspension beam 120, and the lifting beam 100, the lifting ear plate 200 and the fixed clamping plate 400 are welded together to ensure the overall strength and stability during lifting.

[0050] In this embodiment, the fixed clamping plate 400 is provided with a first action surface 401 and a second action surface 402. The two first action surfaces 401 respectively abut against both sides of the hook seat 002 along the length direction of the lifting beam 100 to axially limit the traveling carriage 010. The second action surface 402 abuts against the side baffle 005 of the traveling carriage 010 to provide auxiliary support for the traveling carriage 010.

[0051] To prevent the lifting beam 100 from being unable to pass through the traveling block 010, in the solution of this embodiment, the cross-sections of the lifting lugs 200 and the fixed clamping plate 400 in the longitudinal direction of the lifting beam 100 are both smaller than the lifting ring pin hole 004. The cross-sections of the lifting lugs 200 and the fixed clamping plate 400 can be set to be rectangular.

[0052] In order to ensure that the lifting bar device can rotate in the lifting ring pin hole 004, in the solution of this embodiment, the maximum dimension of the middle beam 110 in the cross section perpendicular to the axial direction is smaller than the width of the lifting ring pin hole 004.

[0053] In summary, the specific working process of the lifting bar device for lifting the traveling carriage provided in this embodiment is as follows:

[0054] Insert the hoisting beam 100 into the bail pin hole 004 at the end of the traveling block 010 away from the main shackle 001 , and adjust the hoisting beam 100 so that the hoisting beam 100 and the traveling block 010 are aligned.

[0055] The hoisting beam 100 is rotated so that the first action surface 401 of the fixed clamping plate 400 abuts against both sides of the hook seat 002 to limit the axial position of the traveling block 010 .

[0056] The hoisting beam 100 is lifted up so that the intermediate beam 110 abuts against the hook seat 002, thereby providing support for the end of the traveling block 010 away from the main shackle 001. At the same time, the second working surface 402 of the fixed clamping plate 400 abuts against the side plate 005 of the traveling block 010, thereby providing auxiliary support for the traveling block 010.

[0057] Lifting bar shackles 300 are installed on the two lifting lugs 200. Wire rope loops are connected to the two lifting bar shackles 300 and the main shackle 001 to lift the traveling block 010. At this point, the projections of the two lifting bar shackles 300 and the main shackle 001 on the horizontal plane form a triangle, ensuring stable lifting of the traveling block.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
