Description

Technical Field

[0001] The utility model relates to the technical field of oil equipment, in particular to a universal hook mounting rack for an oil drilling rig. Background Technique

[0002] As one of the components of the hoisting system of an oil drilling rig, the weight of each type of hook is about 3 - 5 tons, and the overall height dimension is about 3 - 3.5 m. The main components include an upper cylinder body, a lower cylinder body, a hook body, a lifting ring, a lifting ring seat, etc. The main body structure of the cylinder body is cylindrical. After the hook is assembled, it is necessary to conduct a load test according to relevant specifications and design specifications to verify the spring stroke and load capacity. After passing the verification, it is connected to the traveling block on the drill floor and participates in the joint commissioning of the drilling rig. There is a large amount of transportation and hoisting work in the whole manufacturing process.

[0003] After the hook is assembled, its conventional transportation method is horizontal transportation. Since the hook body, lifting ring, and lifting ring seat exceed the cylindrical range of the cylinder body, special support is required for the hook during horizontal transportation, and auxiliary fixation is used to prevent rolling and slipping. Considering the high frequency characteristics of transportation and hoisting work, the horizontal placement efficiency is low, and there is a certain hoisting risk.

[0004] During the joint commissioning of the drilling rig, the hook is lifted from a horizontal state and gradually becomes vertical. There is a certain instability phenomenon in the whole process. After being vertically hoisted and transferred to the drill floor, the hook needs to be adjusted to a certain slope when connecting with the traveling block, and there is still a certain instability risk during the connection process. From the horizontal state to the final vertical connection state during installation, the overall operation efficiency is not high, and there is a certain operation safety risk.

[0005] According to the installation requirements of the overall assembly and joint commissioning of the drilling rig, there is an urgent need for a process equipment to support and fix the hook in a vertical state in advance, meet the overall hoisting and transportation of the hook, enable the hook to be in place on the drill floor in a vertical state, reduce the process links of connecting with the traveling block, improve the overall assembly and commissioning efficiency, and reduce the risk of operation safety hazards. Content of the Utility Model

[0006] The purpose of the utility model is to provide a universal hook mounting rack for an oil drilling rig. This device can not only change the traditional horizontal placement method of the hook to vertical support placement, realize one-time vertical lifting, eliminate the risk of lifting instability, but also enable the hook to be in place in a vertical state in advance for transportation, support, and installation, be hoisted to the drill floor as a whole, eliminate the slope during connection with the traveling block, facilitate the installation during the overall joint commissioning of the drilling rig, and reduce the overall installation operation risk of the drilling rig, so as to solve the problems raised in the background technique.

[0007] To achieve the above object, the utility model provides the following technical solution: A general-purpose oil drilling rig hook mounting bracket, including a frame body with a riveted and welded integrated structure. A reinforcing diagonal brace is connected between the top and bottom of the frame body. A tabletop is provided at the top of the frame body. A hook operation channel is opened at the center of the tabletop. Structural strengthening beams are welded at the corners of the hook operation channel. Lifting lugs are welded on the structural strengthening beams. Flip support frames are respectively hinged at 180° on both sides of the hook operation channel through ear plates and pins. The tabletop, the hook operation channel and the flip support frames form a hook operation platform. A climbing ladder is provided between the tabletop and the bottom of the frame body. Safety guardrails are enclosed around the four sides above the tabletop. The safety guardrail above the climbing ladder is disconnected and connected with a safety chain.

[0008] Preferably, the frame body and the diagonal brace adopt large-size thick-walled square tubes as main components. The climbing ladder is welded with the frame body by using small-section square tubes to form an integrated structure. The height of the climbing ladder reaches the high-position operation tabletop.

[0009] Preferably, the flip support frame is a double-ear plate riveted weldment formed by welding section steel and plates.

[0010] Preferably, when the flip support frame 7 is in the working position, it can self-limit and remain horizontal and provide sufficient support strength for the hook limit. In addition, the set distance of the flip support frame 7 can be applicable to the support limits of hooks of various specifications.

[0011] Preferably, the safety guardrail is welded with the tabletop as a whole. The height of the safety guardrail meets the safety protection requirements for high-altitude operations.

[0012] Preferably, diamond pattern steel plates are laid on the tabletop to enhance the anti-slip function.

[0013] The working principle and process of the utility model are as follows:

[0014] During the joint commissioning of the overall rig assembly, the mounting frame and the hook can be lifted as a whole to the drill floor, enabling the hook and the traveling block to be connected vertically in one go. The structure of the hook mounting frame includes a square tube support frame, diagonal braces, a climbing ladder, a deck plate, a flipping support frame, a guardrail, etc. A large-size thick-walled square tube is used as the main frame structure, and the support height is set at 2.5 m to meet the load-bearing strength and height requirements for the vertical placement of the hook. Diagonal braces are added to the main frame to enhance the overall stiffness and stability of the frame. There is a climbing ladder on the main frame leading to the high-position working deck, and a safety guardrail is set on the high-position working deck. The height of the guardrail meets the safety protection requirements for working at heights. The deck plate is made of diamond pattern steel plate to provide anti-slip function. The flipping support frame on the high-position working deck can be flipped 180°. When the hook is lifted into the mounting frame, the flipping support frame is in the flipped-open state. After the hook is hoisted in place, the flipping frame is manually flipped to its working position. The flipping support frame acts on the bevel edge of the convex ring of the hook sling seat, providing sufficient support force for the hook after it is in place and can limit the hook at a certain height. When the hook is lifted, the flipping mechanism can be flexibly flipped to automatically release the support and limit, without manual operation, reducing the risk of hoisting operations. In addition, the set distance of the flipping support frame can be applicable to the support and limit of hooks of various specifications, having a certain degree of versatility.

[0015] After the hook assembly is completed, during the subsequent tensile test and the joint commissioning of the overall rig assembly, the hook can be lifted and transported to the placement rack. After the hook is in place, the flipping support frame is manually adjusted so that the support frame supports and limits at the position of the hook sling seat. Subsequently, the hook can be lifted in one go on the tooling rack, and the flipping support frame automatically flips open to release the limit, without manual operation. During the joint commissioning of the overall rig assembly, the hook mounting frame and the hook can be lifted and transported to the drill floor as a whole. The driller operates the traveling block to connect with the hook in a vertical state and lifts it in the mounting frame at one time, eliminating the instability risk during the original connection process, shortening the connection process, and improving the overall assembly operation efficiency. After the overall rig assembly and commissioning are completed, the driller can still control the traveling block to lift the hook to the mounting frame and lift it off the drill floor as a whole, keeping the hook in a vertically supported placement state all the time, which is convenient for subsequent hoisting and placement.

[0016] The beneficial effects of the present utility model are as follows:

[0017] (1) The general-purpose oil rig hook mounting frame of the present utility model eliminates the support and fixing links of horizontal transportation. Fully combining the structural characteristics of the hook sling seat of the hook components, a flipping support frame is designed to effectively support and limit the hook, and it can be applicable to the support of hooks of various specifications. The hook can be in a vertical state in the mounting frame, facilitating the vertical lifting of the hook in one go and eliminating the instability risk brought by horizontal hoisting.

[0018] (2) The universal hook mounting frame of the utility model can be lifted as a whole with the hook to the installation position on the drill floor during the joint commissioning of the overall rig assembly. The driller controls the traveling block to be connected to the hook in a vertical state, facilitating the lifting and installation during the hook joint commissioning and reducing the operation safety risks of the conventional installation method.

[0019] (3) The utility model is safe and reliable, simple in structure, convenient to install, and low in manufacturing and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following further describes the utility model in detail with reference to the drawings.

[0025] As Figures 1-3 shown, a universal hook mounting frame for an oil drilling rig includes a frame main body 1 with a riveted and welded integrated structure. A diagonal brace 2 for reinforcement is connected between the top and bottom of the frame main body 1. A tabletop 5 is provided at the top of the frame main body 1. The tabletop 5 is covered with lenticular pattern steel plates to enhance the anti-slip function. In addition, a hook operation channel is opened in the center of the tabletop 5. Structural reinforcing beams are welded at the corners of the hook operation channel, and lifting lugs 6 are welded on the structural reinforcing beams; Tipping support frames 7 are respectively hinged at 180° on both sides of the hook operation channel through ear plates and pins. The tabletop 5, the hook operation channel and the tipping support frames 7 form a hook operation platform; A ladder 4 is provided between the tabletop 5 and the bottom of the frame main body 1. A guardrail 3 surrounds the four sides above the tabletop 5. The guardrail 3 is welded to the tabletop 5 as a whole, and the height of the guardrail 3 meets the safety protection requirements for high-altitude operations; The safety guardrail 3 provided above the ladder 4 is disconnected and connected with a safety chain 8.

[0026] The frame main body 1 and the diagonal brace 2 use large-size thick-walled square tubes as the main components. The ladder 4 uses small-section square tubes and is welded to the frame main body 1 as an integrated structure. The height of the ladder 4 reaches the highest working tabletop 5; The tipping support frame 7 is a double-ear plate riveted weldment composed of section steel and plates. The tipping support frame 7 can be self-limiting and keep horizontal in the working position and provide sufficient support strength for the hook limit. In addition, the setting distance of the tipping support frame 7 can be applicable to the support limits of hooks of various specifications.

[0027] The working principle and working process of the utility model are as follows:

[0028] The utility model is suitable for a universal frame-type structural mounting frame for a large hook, and the structure includes a square tube supporting frame body 1, a diagonal brace 2, a ladder 4, a table 5, a flip support frame 7, a guardrail 3, a lifting lug 6, a safety chain 8 and other parts. The frame body 1 and the diagonal brace 2 use large-size thick-walled square tubes as the main components, and the whole adopts a riveted and welded integrated structure. The frame body adds a diagonal brace to enhance the overall rigidity and stability of the frame to meet the bearing strength and height of the large hook placed vertically. The ladder 4 uses a small-section square tube and the frame body 1 to weld into an integrated structure, and the height of the ladder 4 is up to the high-position working table 5. The high-position working table 5 is provided with a safety guardrail 3 and a safety chain 8. The guardrail 3 and the table 5 are welded into a whole. The height of the guardrail 3 meets the safety protection requirements for high-altitude operations. The table 5 is flatly welded with a lentil pattern steel plate on the frame body 1 to enhance the anti-slip function. The welding adopts intermittent welding to ensure the flatness of the table. The main frame of the table 5 is welded with a lifting lug 6 for overall lifting, which meets the overall lifting requirements of the large hook and the mounting frame. The flip support frame 7 is a double-ear plate riveted welded part made of welded steel sections and plates, and is arranged at the working position of the high-position work table 5. The flip support frame 7 is connected to the table 6 through ear plates and pins, and can be flipped 180°. When in the working position, the flip support frame 7 can limit itself and remain horizontal, providing sufficient supporting strength for the large hook limit. In addition, the setting distance of the flip support frame 7 can be applicable to large hook support limits of various specifications, and has a certain degree of versatility.

[0029] After the hook is assembled, during the subsequent load test and the joint debugging of the drilling rig assembly, the hook can be hoisted to the placement frame. Before the hook is hoisted into the installation frame, the flip support frame 7 is manually flipped to the open state. When the hook is hoisted to the lifting ring seat and initially coincides with the height of the table 5, the flip support frame 7 is manually operated to flip it to a horizontal working position, so that the flip support frame 7 acts on the convex bevel of the hook lifting ring seat, provides sufficient support for the hook after the hook is in place, and limits the hook at a certain height. When the hook is hoisted, the flip support frame 7 can be flexibly flipped to automatically release the support limit without manual operation, reducing the risk of hoisting operation. During the joint debugging of the drilling rig assembly, the hook installation frame and the hook can be hoisted to the drilling table as a whole, and the driller operates the traveling carriage to connect the hook in a vertical state and hoist it in the installation frame at one time. After the drilling rig assembly and debugging are completed, the driller can still control the traveling carriage to hoist the hook to the installation frame, and hoist it away from the drilling table as a whole, so that the hook is always in a vertical support placement state, which is convenient for subsequent hoisting and placement.

[0030] The utility model patent is applicable to a hook, enabling the hook to be in a vertical state waiting for hoisting before subsequent load tests and before the overall assembly and commissioning of the drilling rig, eliminating the process of repeatedly lifting the hook from a horizontal state to a vertical state, reducing the instability risk of hoisting operations. During the process of connecting with the traveling block during overall assembly and commissioning, the connection with the traveling block can be completed in a vertical state, further improving the efficiency of overall assembly operations.

[0031] The above are only the preferred examples of the utility model. It should be pointed out that for those of ordinary skill in the art, under the technical inspiration provided by the utility model and as common general knowledge in the mechanical field, other equivalent variations and improvements can also be made, which should also be regarded as the protection scope of the utility model.
