Description

Technical Field

[0001] The utility model belongs to the technical field of crane pipes, and in particular relates to an anti-winding isolation device for a telescopic sleeve of a submerged oil filling crane pipe used for submerged oil filling. Background Art

[0002] The crane pipe is a device for conveying fluids, especially used when docking with tank trucks during loading and unloading of liquid media. According to the relevant provisions of the national standard "General Guidelines for Preventing Electrostatic Accidents", the crane pipe should be less than 200mm from the bottom of the tank when filling oil, so as to achieve complete underwater loading, effectively reduce oil splashing and volatilization loss, and prevent static electricity. Therefore, the crane pipe must not only meet the requirements of underwater oil filling, but also meet the elevation of the crane pipe so that the tank truck can enter safely, and shorten the length of the crane pipe, that is, the crane pipe casing must be able to move up and down without power. The current practice is to set a counterweight in the crane pipe to balance the weight of the casing. When filling oil, the counterweight moves upward under the action of the oil flow, and the casing moves downward to achieve the extension of the crane pipe, so as to achieve the operating requirement that the distance between the oil filling crane pipe and the bottom of the tank is less than 200mm. When the oil filling stops, the casing moves upward under the action of the counterweight to achieve the retraction of the casing.

[0003] There are crane pipes on the market that can prevent entanglement of wire ropes. However, although they can prevent wire rope entanglement during use, the main reason is that the counterweight runs on a limit track. When the ambient temperature drops, the loading medium will crystallize in the tank. The formed crystals will jam the counterweight and the limit track, causing the casing to be unable to extend or retract.

[0004] Therefore, the present application proposes an anti-entanglement isolation device for a telescopic sleeve of an underwater oil loading crane pipe, which has a simple structure, is easy to use, and can prevent the entanglement of wire ropes and the jamming of counterweight blocks. Summary of the invention

[0005] The utility model provides an anti-winding isolation device for a telescopic sleeve of an underwater oil-filled crane pipe, which can effectively solve the problem that a counterweight and a steel wire rope are entangled or stuck during use of the crane pipe, so that the sleeve cannot be telescoped.

DETAILED DESCRIPTION

[0028] The above contents of the present invention are further described in detail below through embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1: Reference Figures 1 to 4 , is a schematic structural diagram of Example 1 of the utility model, which discloses an anti-winding isolation device for a telescopic sleeve of a submerged oil loading crane pipe, comprising a flange (1), a pulley frame (2), a pulley (3), an inner pipe (4), a steel wire rope (5), a sleeve connecting ring (6), a sleeve (7), a pulley shaft (8), an isolation mechanism (9), a counterweight (10), an isolation mechanism fixing ring (11), a limiting ring (12), a guide head (13) and a steel wire rope clamp (14),

[0030] The inner tube (4) and the sleeve (7) are plugged into each other. A pulley (3) is provided at the lower end of the pulley frame (2) on the flange (1). The wire rope (5) passes around the pulley (3). One end of the wire rope passes through the center hole of the counterweight (10) and is connected with a wire rope clamp (14). The other end passes through the center hole of the guide head (13) at the lower end of the sleeve (7) and is connected with the wire rope clamp (14). An isolation mechanism (9) is provided inside the inner tube (4). The upper end of the isolation mechanism (9) is connected to the pulley frame (2), and the lower end is connected to the isolation mechanism fixing ring (11). The flange (1) is provided at the upper end of the inner tube (4), and the isolation mechanism fixing ring (11) is provided at the lower end of the inner tube (4). The isolation mechanism (9) is installed in the inner tube (4), and the counterweight (10) can only move up and down on one side of the isolation mechanism (9). The gap of the isolation mechanism (9) is smaller than the size of the counterweight (10), that is, the counterweight (10) cannot pass through the gap of the isolation mechanism (9).

[0031] The sleeve (7) is mounted outside the inner tube (4), and the sleeve (7) can move up and down outside the inner tube (4). The inner tube (4) is provided with a flange (1), a pulley frame (2), a pulley (3), a wire rope (5), a pulley shaft (8), an isolation mechanism (9), a counterweight (10), and an isolation mechanism fixing ring (11). The isolation mechanism (9) is connected to the pulley frame (2) at its upper end and to the isolation mechanism fixing ring (11) at its lower end. One end of the wire rope (5) passes through the pulley (3) and through the center hole of the counterweight (10) and is connected with a wire rope clamp (14), and the other end passes through the center hole of the guide head (13) at the lower end of the sleeve (7) and is connected with the wire rope clamp (14).

[0032] The counterweight (10) is installed on one side of the isolation mechanism (9) and moves up and down, and does not contact the steel wire rope (5) on the other side of the isolation mechanism (9), so as to prevent the counterweight (10) and the steel wire rope (5) from getting entangled when the counterweight (10) swings under the action of the oil flow. The isolation mechanism (9) can be an isolation fence, or an isolation net or isolation board. In this embodiment, the isolation mechanism is an isolation fence, and the isolation fence is a grid-like shape formed by a plurality of strips arranged at intervals.

[0033] The isolation mechanism fences are provided with a plurality of bars, and the gap between two isolation mechanism fences is smaller than the size of the counterweight.

[0034] A limiting ring (12) is provided at the lower end of the outer wall of the inner tube (4), and a sleeve connecting ring (6) is provided at the upper end of the sleeve (7). The limiting ring (12) and the sleeve connecting ring (6) function to limit the downward movement of the sleeve (7). The sleeve (7) can be installed outside or inside the inner tube (4). In this embodiment, the sleeve (7) is outside the inner tube (4).

[0035] The upper end of the inner tube (4) is welded to the flange (1), and a limiting ring (12) is welded to the outer side of the lower end. The inner hole at the upper end of the sleeve (7) is provided with a sleeve connecting ring (6). When the sleeve (7) runs downward to the end, the sleeve connecting ring (6) falls on the limiting ring (12) and does not fall off.

[0036] The lower end of the sleeve (7) is connected to a flow guide head (13) which can change the flow direction of the fluid and prevent the oil from directly impacting and penetrating the bottom during loading.

[0037] A pulley frame (2) is provided at the upper end of the inner tube (4), and an isolation mechanism fixing ring (11) is provided at the lower end. An isolation mechanism (9) is provided between the pulley frame (2) and the isolation mechanism fixing ring (11). The upper end of the isolation mechanism (9) is connected to the pulley frame (2), and the lower end of the isolation mechanism (9) is connected to the isolation mechanism fixing ring (11). The counterweight (10) is on one side of the isolation mechanism (9) and is hung on the pulley (3) through the steel wire rope (5). One end of the steel wire rope (5) passes through the center hole of the counterweight (10) and is locked by a locking clip (14), and the other end passes through the center hole of the guide head (13) at the lower end of the sleeve (7) and is locked by the locking clip (14).

[0038] In actual use: when filling with oil, the impact force of the fluid on the guide head (13) causes the sleeve (7) to move downward, and the other end of the wire rope (5) fixed on the guide head (13) connects the counterweight (10) through the pulley (3) and lifts it upward. When the sleeve connecting ring (6) at the upper end of the sleeve (7) falls on the limiting ring (12) at the lower end of the inner tube (4), the counterweight (10) just reaches the upper end of the inner tube (4).

[0039] When the oil filling is completed, the oil filling sleeve (7) moves downward along one side of the isolation mechanism (9) under the action of the gravity of the counterweight (10), and the oil filling sleeve (7) is automatically retracted and reset, and the mass of the counterweight (10) is greater than the mass of the sleeve (7).

[0040] The isolation mechanism (9) is installed in the inner tube (4), the upper end of which is connected to the pulley frame (2), and the lower end of which is connected to the isolation mechanism fixing ring (11), so that two independent channels are formed in the inner tube (4). The counterweight (10) moves up and down in the space on one side of the isolation mechanism (9) and does not contact the steel wire rope (5) connected to the guide head (13) in the space on the other side. The counterweight (10) can only move up and down on one side of the isolation mechanism (9) and will not be entangled with the steel wire rope (5) when swinging under the action of the oil flow, thereby avoiding the balancing device from losing its function and causing the sleeve (7) to be unable to move up and down.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several changes and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.

[0042] Example 2: Reference Figure 5 , is a schematic diagram of the structure of Example 2 of the utility model. Compared with Example 1, the difference between this example and Example 1 is that the isolation mechanism uses an isolation net or isolation plate, and the isolation net or isolation plate can prevent the counterweight (10) from being entangled with the steel wire rope on the other side of the isolation net or isolation plate during the up and down movement.

[0043] The figure shows the setting position of the isolation board or isolation net.

[0044] Example 3: Reference Figure 6 , is a schematic diagram of the structure of Example 3 of the utility model. Compared with Example 1, the difference between this embodiment and Example 1 is that the isolation mechanism uses an isolation cylinder, and the counterweight moves up and down in the isolation cylinder. The isolation cylinder can prevent the counterweight (10) from being entangled with the wire rope on the other side of the isolation net or isolation plate during the up and down movement.
