Technical Field

[0001] The utility model relates to the technical field of petroleum pipeline hoisting, in particular to a safety protection device for the installation of a petroleum pipeline. Background Art

[0002] The oil pipeline (also called pipeline, pipeline) is composed of oil pipes and their accessories, and is equipped with corresponding oil pump units according to the needs of the process flow. It is designed and installed into a complete pipeline system to complete the tasks of oil loading and unloading and transfer.

[0003] During the installation of the oil pipeline, a crane is needed to lift, transfer and assemble the oil pipeline. During this process, a rope needs to be passed under the oil pipeline and wrapped around the outer wall of the oil pipeline, and then the rope is connected to the crane hook. When passing the rope under the oil pipeline, a space gap is required between the bottom of the oil pipeline and the ground to complete the installation. In this way, the oil pipeline needs to be lifted by another lifting equipment, or a pad needs to be placed at the bottom of the oil pipeline when the oil pipeline is placed on the ground. Both of these operation methods increase the installation workload of the oil pipeline. When the oil pipeline is lifted by a rope, the pipeline is prone to deviation. Based on this, a safety protection device for the installation of a petroleum pipeline is provided. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 4 In the embodiment of the utility model, a safety protection device for the installation of a petroleum pipeline includes a hoisting assembly 2 for clamping an oil pipeline 1. The hoisting assembly 2 includes a clamping unit and a hoisting unit. The clamping unit is used to clamp the outer side of the hoisting assembly 2 without passing under the hoisting assembly 2, so as to facilitate hoisting in the later stage. The hoisting unit is used to connect with the hook of the hoisting equipment, and lock and reinforce the splicing state of the clamping unit;

[0028] The clamping unit includes a first arc-shaped piece 201, a second arc-shaped piece 202, a first plug-in piece 203a, a second plug-in piece 203b and a plug-in slot 204. The first arc-shaped piece 201 and the second arc-shaped piece 202 are symmetrically distributed on the outside of the oil pipeline 1. The "C"-shaped structure formed by the first arc-shaped piece 201 and the second arc-shaped piece 202 wraps and clamps the outer wall of the oil pipeline 1. The first plug-in piece 203a and the second plug-in piece 203b are respectively fixed to the end faces of the first arc-shaped piece 201 and the second arc-shaped piece 202 spliced ​​with each other, and the first plug-in piece 203a and the second plug-in piece 203b are staggered in the horizontal direction.

[0029] The plug-in slot 204 is provided at the end surface where the first arc-shaped piece 201 and the second arc-shaped piece 202 are spliced ​​with each other and penetrates to the other end of the first arc-shaped piece 201 and the second arc-shaped piece 202. The first plug-in component 203a and the second plug-in component 203b include a fixed plug-in block 2031 fixed to the end surface of the first arc-shaped piece 201 and the second arc-shaped piece 202. The first arc-shaped piece 201 and the second arc-shaped piece 202 are plugged into the inner side of the plug-in slot 204 through the fixed plug-in block 2031 to realize the docking operation.

[0030] The hanging unit includes a rotating plug block 2032 and a hanging slot 2033;

[0031] The rotating plug block 2032 is rotatably connected to one end of the fixed plug block 2031 through a rotating pin. When the fixed plug block 2031 is inserted into the plug slot 204, the rotating plug block 2032 passes through the plug slot 204 to the outside of the first arc piece 201 and the second arc piece 202.

[0032] The hanging groove 2033 is opened at the top of one end of the rotating block 2032 away from the fixed block 2031 and passes through the rotating block 2032. The rotating block 2032 is hooked and connected with the lifting equipment through the hanging groove 2033. The rotating block 2032 is pulled to a vertical state by the lifting equipment to realize the card connection and locking of the fixed block 2031 and the insertion groove 204.

[0033] In this embodiment: when the oil pipeline 1 is hoisted, two people can stand on both sides of the oil pipeline 1 holding the first arc piece 201 and the second arc piece 202 respectively, and then fit the first arc piece 201 and the second arc piece 202 to the outer wall of the oil pipeline 1. At this time, the first plug 203a on the first arc piece 201 is inserted into the plug groove 204 on the second arc piece 202, and the second plug 203b on the second arc piece 202 is inserted into the plug groove 204 on the first arc piece 201. When the end faces of the first arc piece 201 and the second arc piece 202 are in contact with each other, the plug block 2032 is rotated to complete the penetration of the plug groove 204.

[0034] Then, the hook on the lifting device is hooked into the hanging groove 2033 on the rotating plug block 2032, and the rotating plug block 2032 is pulled and rotated to a vertical state by tightening the rope of the lifting device. At this time, the fixed plug block 2031 and the rotating plug block 2032 are in an "L" shape as a whole, so that the fixed plug block 2031 is limited inside the plug groove 204, and its first arc 201 and the second arc piece 202 are connected and fixed to each other, thereby realizing the connection between the lifting component 2 and the oil pipeline 1;

[0035] Then, the second lifting assembly 2 is installed to the oil pipeline, and the oil pipeline 1 is lifted and transferred by the lifting equipment. After the transfer is completed, the lifting assembly 2 can be easily disassembled and reused;

[0036] The oil pipeline can be easily hoisted by the cooperation of the above multiple parts. Compared with the traditional operation method of passing the rope under the oil pipeline, the installation of the first arc 201 and the second arc piece 202 does not need to pass under the oil pipeline, and the operation is simpler and more convenient. The larger contact area between the first arc 201, the second arc piece 202 and the oil pipeline 1 can avoid deviation during the hoisting process (it should be supplemented that the first arc 201 and the second arc piece 202 can be provided with a rubber layer to further increase the friction).

[0037] Please refer to Figures 3-4 The horizontal widths of the fixed plug block 2031 and the rotating plug block 2032 match the inner wall width of the plug slot 204 , and the distance between the rotating connection point of the fixed plug block 2031 and the rotating plug block 2032 to the fixed point of the fixed plug block 2031 matches the depth of the plug slot 204 .

[0038] In this embodiment: through this structure, after the fixed plug 2031 is fully inserted into the plug-in slot 204, the rotating plug 2032 passes through the plug-in slot 204, and the rotating plug 2032 can rotate. When the rotating plug 2032 is rotated to a vertical state, it will fit with the end face of the plug-in slot 204, ensuring that the first arc piece 201 and the second arc piece 202 are plugged stably to avoid looseness.

[0039] Please refer to Figures 1 to 4 The end surface where the bottom end of the rotating plug block 2032 contacts the fixed plug block 2031 is a vertical surface, and the surface where the top end of the rotating plug block 2032 contacts the fixed plug block 2031 is an arc surface structure.

[0040] In this embodiment: through this structure, when the rotating plug block 2032 is rotated to a horizontal state with the fixed plug block 2031, it cannot continue to rotate downward, so that the plugging operation with the plug slot 204 is convenient;

[0041] The top arc surface structure of the rotating plug block 2032 enables it to rotate upward to a vertical state.

[0042] Please refer to Figures 1 to 4 There are two groups of first connectors 203a, which are symmetrically distributed with the second connector 203b as the center. The number and position of the connector slots 204 on the first arc-shaped piece 201 and the second arc-shaped piece 202 correspond to the first connector 203a and the second connector 203b one by one.

[0043] In this embodiment, the number of hooks connecting the hoisting equipment to a hoisting assembly 2 is three, and the connection points between the three hooks and the first connector 203a and the second connector 203b are distributed in a triangle, so that good stability can be maintained during hoisting.

[0044] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
