[0049] Example 1

[0050] This invention provides an oil pipe cavity access device, such as... Figure 1 As shown, the tubing passage device is located on the same axis as the construction tubing, and includes: a passage gauge 1, a force transmission tube 2, a drive assembly, and an oil / wax collection device 3, wherein:

[0051] The vent gauge 1 includes at least a milled tooth gauge body 1-5. The milled tooth gauge body 1-5 includes a diameter inspection gauge body 1-5-1 and a dewaxing structure 1-5-2. The diameter inspection gauge body 1-5-1 is cylindrical, and its outer diameter is 1-2 mm smaller than the inner diameter of the construction tubing. The dewaxing structure 1-5-2 is located at the end of the diameter inspection gauge body 1-5-1 facing the construction tubing and is used to remove wax from the construction tubing. The outer diameter of the diameter inspection gauge body 1-5-1 is 1-2 mm smaller than the inner diameter of the construction tubing, making its outer diameter larger than the diameter of the vent gauge for the construction tubing (industry standards stipulate that the diameter of the vent gauge should be 2-2.5 mm smaller than the diameter of the construction tubing). Its function is to rotary cut away all adhering substances such as wax and scale within the inner cavity of the construction tubing, up to the outer diameter of the diameter inspection gauge body 1-5-1, to ensure the venting requirements of the construction tubing are met.

[0052] One end of the force transmission tube 2 is connected to the through cavity gauge 1, and the other end is connected to the drive assembly.

[0053] The oil and wax collection device 3 is connected to the through-cavity gauge 1 and is used to collect the oil and wax removed by the dewaxing structure 1-5-2.

[0054] The driving assembly is used to drive the force transmission pipe 2 to rotate.

[0055] The oil pipe cavity passing device disclosed by the embodiment of the present application drives the cavity passing gauge 1 to rotate through the driving assembly, the wax removing structure 1-5-2 removes the oil wax of the working oil pipe, and the diameter checking gauge body 1-5-1 checks the diameter of the working oil pipe. Compared with the prior art, the scheme of first using the high-temperature steam of the boiler car to remove the wax and then using the drift gauge to check the diameter of the working oil pipe shortens the maintenance time and improves the construction efficiency. In addition, the oil wax removed under the action of external force is brought to the oil wax collecting device 3 for point control discharge, thereby avoiding the problem of pollution caused by the oil wax falling to the ground or rising.

[0056] In some embodiments, as shown in Figure 2 The cavity passing gauge 1 further comprises a connecting sleeve 1-1 in the diameter checking gauge body 1-5-1, and the connecting sleeve 1-1 is connected with the force transmission pipe 2. In a specific example, one end of the force transmission pipe 2 connected with the connecting sleeve 1-1 is provided with a jet pipe assembly 2-1, the force transmission pipe 2 is internally provided with a sealed gas cavity for gas supply, the jet pipe assembly 2-1 comprises a jet pipe support 2-1-1 and a jet pipe (not shown in the figure) connected with the sealed gas cavity, the jet pipe support 2-1-1 comprises a support body 2-1-1-1 and a protruding part 2-1-1-2 arranged at both ends of the support body 2-1-1-1, the jet pipe is in communication with the protruding part 2-1-1-2, and the connecting sleeve 1-1 is provided with a slot hole (not shown in the figure) matched with the protruding part 2-1-1-2. The protruding part 2-1-1-2 enters the slot hole, and the protruding part 2-1-1-2 and the slot hole can be connected through interference fit, of course, the connection mode can also be bolt connection, pin connection and the like, as long as the movable connection of the connecting sleeve 1-1 and the force transmission pipe 2 can be realized. The number of the jet pipes is the same as the number of the slot holes.

[0057] In a specific embodiment, as shown in Figure 2 The connecting sleeve 1-1 is provided with a positioning hole 1-1-1 at one end close to the force transmission pipe 2, and the cavity passing gauge 1 further comprises a positioning bolt 1-6 matched with the positioning hole 1-1-1, so that the protruding part 2-1-1-2 cannot be separated from the slot hole after being matched with the slot hole. The positioning bolt 1-6 is located between the slot hole and the one end of the connecting sleeve 1-1 close to the force transmission pipe 2, the positioning bolt 1-6 passes through the connecting sleeve 1-1 after the protruding part 2-1-1-2 enters the slot hole, so that the protruding part 2-1-1-2 cannot be separated from the slot hole.

[0058] In a specific embodiment, as shown in Figure 4As shown, the protruding part 2-1-1-2 is provided with a reinforcing rib 2-7 on the inner side of the connecting position of the bracket body 2-1-1-1. The reinforcing rib 2-7 can strengthen the connecting position of the protruding part 2-1-1-2 and the bracket body 2-1-1-1, and prevent the connecting sleeve 1-1 from being damaged by frequent rotation.

[0059] In some embodiments, the combination of Figure 2 and Figure 3 As shown, the through cavity gauge 1 further comprises a baffle 1-2, a scraper group 1-4, and a connecting gauge spoke 1-3. One end of the baffle 1-2 is connected to the end of the connecting sleeve 1-1 away from the force transmission pipe 2, and the other end is connected to the scraper group 1-4. The two ends of the connecting gauge spoke 1-3 are connected to the baffle 1-2 and the diameter checking gauge body 1-5-1 respectively. The connecting gauge spoke 1-3 comprises at least two partitions which are uniformly arranged along the inner wall circumference of the diameter checking gauge body 1-5-1. The scraper group 1-4 uniformly cuts the oil wax, scale and the like separated by the tooth milling gauge body 1-5 into pieces through a plurality of conical blades, so as to pass through the connecting gauge spoke 1-3. The baffle 1-2 controls the passage of oil wax, scale and the like through the connecting gauge spoke 1-3 and achieves the connection and fixation of one end of the connecting gauge spoke 1-3. The at least two partitions of the connecting gauge spoke 1-3 are uniformly arranged along the inner wall circumference of the diameter checking gauge body 1-5-1, so that the components are uniformly stressed to avoid local overload damage, and the oil wax, scale and the like passing through this part are uniformly divided to avoid blocking the passage by large pieces.

[0060] In some embodiments, as Figure 4 As shown, the force transmission pipe 2 comprises a pipe body, a dead plug 2-3, a movable plug 2-6, and an air inlet hole 2-4. The dead plug 2-3 is located at one end of the pipe body close to the driving assembly. The movable plug 2-6 is connected to one end of the pipe body close to the through cavity gauge 1. The area surrounded by the pipe body, the dead plug 2-3, and the movable plug 2-6 forms a sealed gas cavity. The air inlet hole 2-4 is used to supply gas to the sealed gas cavity.

[0061] In one specific embodiment, as Figure 4 As shown, the force transmission pipe 2 further comprises a constant pressure air release valve 2-5 connected to the pipe body, which is arranged close to the jet bracket 2-1-1. The constant pressure air release valve 2-5 is used to control the supply of gas to the jet pipe, and to supply gas with constant pressure and quantity. The constant pressure air release valve 2-5 can be a spring type air release valve, which is simple to operate and economical and practical.

[0062] In some embodiments, as Figure 1As shown, the oil wax collecting device 3 is a four-way pollution discharge sleeve, which includes a first channel 3-1, a second channel 3-4, a third channel 3-3, and a fourth channel 3-2. The first channel 3-1 accommodates the through-cavity gauge 1, and the outer wall of the first channel 3-1 is connected with the construction oil pipe. The second channel 3-4 allows the transmission pipe 2 to pass through. The third channel 3-3 is located below the first channel 3-1 and is used for directional collection of oil wax. The fourth channel 3-2 is located on the opposite side of the third channel 3-3 and is used for filtering the air discharged from the jet pipe assembly 2-1. Specifically, the first channel 3-1 forms a sealed cavity on the side close to the transmission pipe 2, and the jet pipe is located in the sealed cavity and is arranged away from the through-cavity gauge 1. The outlet direction of the jet pipe is parallel to the axis of the diameter inspection gauge body 1-5-1. The gas is delivered to the jet pipe by the through-jet gas package 4 through the transmission pipe 2, and the reaction force of the gas makes the through-cavity gauge 1 have an advancing thrust to move towards the construction oil pipe. The direct force of the gas makes the oil wax move away from the diameter inspection gauge body 1-5-1. The fourth channel 3-2 is used for filtering the air discharged from the jet pipe assembly 2-1 through a filter screen or the like. By using density separation, the air naturally floats up into the fourth channel 3-2, and the solid and liquid naturally fall down into the third channel 3-3.

[0063] In one embodiment, the oil wax collecting device 3 is a four-way pollution discharge sleeve, which includes a first channel 3-1, a second channel 3-4, a third channel 3-3, and a fourth channel 3-2. The first channel 3-1 accommodates the through-cavity gauge 1, and the outer wall of the first channel 3-1 is connected with the construction oil pipe. The second channel 3-4 allows the transmission pipe 2 to pass through. The third channel 3-3 is located below the first channel 3-1 and is used for directional collection of oil wax. The fourth channel 3-2 is located on the opposite side of the third channel 3-3 and is used for filtering the air discharged from the jet pipe assembly 2-1. Specifically, the first channel 3-1 forms a sealed cavity on the side close to the transmission pipe 2, and the jet pipe is located in the sealed cavity and is arranged away from the through-cavity gauge 1. The outlet direction of the jet pipe is parallel to the axis of the diameter inspection gauge body 1-5-1. The gas is delivered to the jet pipe by the through-jet gas package 4 through the transmission pipe 2, and the reaction force of the gas makes the through-cavity gauge 1 have an advancing thrust to move towards the construction oil pipe. The direct force of the gas makes the oil wax move away from the diameter inspection gauge body 1-5-1. The fourth channel 3-2 is used for filtering the air discharged from the jet pipe assembly 2-1 through a filter screen or the like. By using density separation, the air naturally floats up into the fourth channel 3-2, and the solid and liquid naturally fall down into the third channel 3-3. Figure 1 Figure 2 As shown, the length of the inner cavity of the first channel 3-1 is more than 2 cm shorter than the length of the diameter inspection gauge body 1-5-1. Since the construction oil pipe and the external wall of the first channel 3-1 are connected by a coupling, there is a relief groove with a diameter larger than the inner diameter of the construction oil pipe between the two female threads of the coupling. In actual use, the tips of the two male threads are generally 2 cm apart. Therefore, the length of the first channel 3-1 needs to be more than 2 cm shorter than the length of the diameter inspection gauge body 1-5-1, so as to facilitate the manual connection of the coupling of the construction oil pipe and the introduction of the top of the through-cavity gauge 1 into the inner cavity of the construction oil pipe, and avoid the diameter inspection gauge body 1-5-1 being stuck in the relief groove of the coupling when advancing.

[0064] In some embodiments, the oil wax collecting device 3 is a four-way pollution discharge sleeve, which includes a first channel 3-1, a second channel 3-4, a third channel 3-3, and a fourth channel 3-2. The first channel 3-1 accommodates the through-cavity gauge 1, and the outer wall of the first channel 3-1 is connected with the construction oil pipe. The second channel 3-4 allows the transmission pipe 2 to pass through. The third channel 3-3 is located below the first channel 3-1 and is used for directional collection of oil wax. The fourth channel 3-2 is located on the opposite side of the third channel 3-3 and is used for filtering the air discharged from the jet pipe assembly 2-1. Specifically, the first channel 3-1 forms a sealed cavity on the side close to the transmission pipe 2, and the jet pipe is located in the sealed cavity and is arranged away from the through-cavity gauge 1. The outlet direction of the jet pipe is parallel to the axis of the diameter inspection gauge body 1-5-1. The gas is delivered to the jet pipe by the through-jet gas package 4 through the transmission pipe 2, and the reaction force of the gas makes the through-cavity gauge 1 have an advancing thrust to move towards the construction oil pipe. The direct force of the gas makes the oil wax move away from the diameter inspection gauge body 1-5-1. The fourth channel 3-2 is used for filtering the air discharged from the jet pipe assembly 2-1 through a filter screen or the like. By using density separation, the air naturally floats up into the fourth channel 3-2, and the solid and liquid naturally fall down into the third channel 3-3.
