Description

Technical Field

[0001] This utility model relates to the field of pipeline emergency repair technology, and in particular to a grease wall propulsion device. Background Technology

[0002] When a large-scale corrosion perforation occurs in a section of an oil pipeline, leading to an oil and gas leak, the situation is extremely critical, requiring immediate replacement of the affected section. During pipeline sealing and emergency repair operations, residual paraffin and petroleum substances on the external pipe wall will continue to generate oil and gas. Welding operations performed nearby could easily ignite a fire or even an explosion. To ensure operational safety, a grease wall is used to seal the oil pipeline, achieving oil and gas isolation.

[0003] Traditionally, grease bricks are first manually shaped and then laid, a process that is extremely complex and time-consuming, resulting in low efficiency in grease wall construction. Furthermore, manual construction is labor-intensive, and the quality largely depends on the experience of the workers, making reliability difficult to guarantee. This also compromises the seal between the grease wall and the pipe's inner wall, compromising the safety of subsequent operations. Existing grease wall advancing devices cannot ensure the integrity of the grease wall during advancement and are structurally complex and inconvenient to operate. Utility Model Content

[0046] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0047] like Figures 1 to 3As shown, this embodiment provides a grease wall propulsion device, including a movable base 1, a container 2, a clamping structure 3, and a pushing structure 4. The movable base 1 is movably set on the ground. The container 2 is placed on the movable base 1 and coaxially arranged with the pipe 100 to be repaired. The container 2 is used to hold the precast grease wall. The clamping structure 3 is set on the movable base 1 and clamps the container 2 at the connection between the pipe 100 and the container 100. The pushing structure 4 includes a drive component 41 and a pushing plate 42. The drive component 41 is set on the movable base 1 and connected to the output end of the drive component 41. Under the drive of the drive component 41, the pushing plate 42 can push the precast grease wall into the pipe 100 to achieve rapid sealing of the pipe 100, ensuring the safety of subsequent operations. It eliminates the need for manual construction and manual pushing of the precast grease wall, greatly reducing labor intensity and improving work efficiency. Furthermore, the height of the movable base 1 is adjustable, allowing for flexible adjustment of the position of the container 2 according to the actual height of the pipeline to be repaired, thus providing good applicability. In addition, since the jacking plate 42 is in surface contact with the precast grease wall, the integrity of the precast grease wall can be ensured during the jacking process.

[0048] Specifically, the butter wall can be made in advance in container 2 to shorten the operation time.

[0049] Optionally, the movable base 1 includes a base plate 11, a top plate 12, a scissor lift support frame 13, and a lifting drive mechanism. The base plate 11 is movably mounted on the ground, and the top plate 12 is spaced above the base plate 11 to support the container 2. The scissor lift support frame 13 is positioned between the base plate 11 and the top plate 12. The fixed end of the lifting drive mechanism is located on the base plate 11, and the output end is connected to the top plate 12. Driven by the lifting drive mechanism, the top plate 12 can be vertically raised and lowered. Simultaneously, the scissor lift support frame 13 extends and retracts synchronously to adjust the height of the container 2 according to the position and height of the pipeline 100 to be repaired, ensuring a coaxial connection between the pipeline 100 and the container 2. Exemplarily, the lifting drive mechanism is a motor commonly used in the art, and the scissor lift frame is also a structure disclosed in the prior art.

[0050] Furthermore, the bottom side of the base plate 11 is provided with multiple casters 111 to facilitate the overall movement of the device at the work site and improve work efficiency. Specifically, in this embodiment, four casters 111 are provided; in other embodiments, the number of casters 111 can be set as needed, and no specific limitation is made here. In addition, the casters 111 can be casters 111 with locking function disclosed in the prior art. When the container 2 is aligned with the pipe 100, the casters 111 are locked to prevent the entire device from moving during the subsequent advancement of the grease wall.

[0051] Optionally, the movable base 1 is provided with an arc-shaped groove 14, and the container 2 is placed in the arc-shaped groove 14. The curved shape of the arc-shaped groove 14 fits more closely to the outer wall of the container 2, providing a larger contact area, evenly distributing the load, and at the same time, it can provide a certain restraint for the container 2, effectively preventing the container 2 from rolling or slipping, and has high stability. Specifically, in this embodiment, the arc-shaped groove 14 is provided on the top plate 12.

[0052] Optionally, the clamping structure 3 includes a first arc-shaped plate 31, a second arc-shaped plate 32, and a plurality of fasteners 33. The first arc-shaped plate 31 and the second arc-shaped plate 32 are respectively disposed on opposite sides of the connection between the container 2 and the pipe 100. The fasteners 33 pass through the first arc-shaped plate 31 and the second arc-shaped plate 32 so that the first arc-shaped plate 31 and the second arc-shaped plate 32 are stably clamped at the connection, ensuring the stability of the connection between the two.

[0053] Specifically, in this embodiment, both ends of the first arc plate 31 are provided with a first connecting part, and the first connecting part has multiple first through holes. Both ends of the second arc plate 32 are provided with a second connecting part, and the second connecting part has multiple second through holes. The first through holes, the second through holes and the fasteners 33 correspond one-to-one. The fasteners 33 include bolts and nuts. The bolts pass through the first through holes and the second through holes, and the nuts are screwed onto the bolts to achieve a fixed connection between the first arc plate 31 and the second arc plate 32. The operation is simple and convenient.

[0054] Optionally, the drive assembly 41 includes a jacking drive mechanism 411 and a telescopic rod 412. The jacking drive mechanism 411 is disposed on the movable base 1, and the telescopic rod 412 extends horizontally and connects the output end of the jacking drive mechanism 411 to the jacking plate 42. Driven by the jacking drive mechanism 411, the telescopic rod 412 can drive the jacking plate 42 to move horizontally. This configuration can replace manual labor in advancing the precast grease wall, reducing labor intensity and saving time and effort.

[0055] In this specific embodiment, the jacking drive mechanism 411 is a hydraulic station, and the telescopic rod 412 is a hydraulic rod. A supply pipe 413 and an outlet pipe 414 connect the hydraulic station and the hydraulic rod. The hydraulic oil pressurized by the hydraulic station is sent to the rear of the piston rod of the hydraulic rod, i.e., the rodless chamber, through the supply pipe 413 to push the piston rod of the hydraulic rod to extend. When the piston rod needs to retract, the hydraulic oil is introduced into the rod chamber on the piston rod side, pushing the piston rod to retract inward, and the hydraulic oil in the rodless chamber is discharged back to the oil tank through the outlet pipe 414.

[0056] More specifically, the hydraulic station is connected to the motor, which converts electrical energy into mechanical energy to ensure the normal operation of the hydraulic station.

[0057] Alternatively, in other embodiments, the motor can be used to directly drive the horizontal movement of the push plate 42. As long as the push plate 42 can be driven to move horizontally, the precast grease wall can be pushed into the pipe 100.

[0058] Furthermore, a diagonal rod is provided on the top plate 12 of the movable base 1, and the end of the telescopic rod 412 away from the push plate 42 is fixedly installed on the diagonal rod. While saving space, the diagonal rod can also be used as a handle to facilitate the movement of the push device.

[0059] Optionally, the jacking plate 42 includes a connecting plate 421 and a rubber cup 422. The connecting plate 421 is located at the output end of the drive assembly 41. The rubber cup 422 is detachably connected to the connecting plate 421, and the diameter of the rubber cup 422 is larger than the diameter of the connecting plate 421. The rubber cup 422 is used to abut against the precast grease wall. The rubber cup 422 itself is elastic and can fit well against the inner wall of the pipe 100 to ensure that the precast grease wall is completely jacked into the pipe 100. Furthermore, the rubber cup 422 is made of rubber material, which can prevent the accumulation of static electricity during the jacking process, effectively avoid static electricity causing sparks, and ensure safety during operation.

[0060] Specifically, the connecting plate 421 is made of steel or iron plate, which has high hardness; while the cup 422 can be a scrapped pig cup 422, so as to achieve material reuse, reduce operating costs, and have good economic benefits.

[0061] Furthermore, the push plate 42 also includes multiple connectors. The connecting plate 421 has multiple first connecting holes spaced apart circumferentially, and the cup 422 has multiple second connecting holes spaced apart circumferentially. The first connecting holes, second connecting holes, and connectors correspond one-to-one, and the connectors pass through the second connecting holes and are fixed to the first connecting holes by screwing, so as to realize the detachable connection between the cup 422 and the connecting plate 421. Specifically, in this embodiment, the second connecting hole is a through hole, the first connecting hole is a threaded hole, and the connector is a bolt; in other embodiments, both the first and second connecting holes may be through holes, and the connectors may be bolts and nuts.

[0062] For example, four of each of the first connecting hole, the second connecting hole, and the connector are provided.

[0063] Optionally, the leather cup 422 has multiple anti-static holes spaced apart along its circumference. Precast grease walls are prone to generating static electricity due to friction during installation. The holes help release static electricity, accelerate charge dissipation, reduce the risk of electrostatic sparks, and improve operational safety. Specifically, the number of anti-static holes can be set as needed and is not specifically limited here.

[0064] Optionally, the cup 422 is annular, with its outer diameter larger than that of the connecting plate 421. This annular design allows the thrust of the drive structure to primarily act on the annular area near the inner wall of the pipe 100, more effectively applying pressure to the contact surface between the pre-formed grease wall and the inner wall of the pipe 100, significantly reducing the risk of leakage of the pre-formed grease wall from the gap between the edge of the cup 422 and the inner wall of the pipe 100. Furthermore, compared to a disc-shaped cup 422, the annular cup 422 has a smaller contact area with the pre-formed grease wall, reducing adhesion and residue of the pre-formed grease wall on the cup 422.

[0065] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
