Description

Technical Field

[0001] The invention relates to a shallow sea pipeline gallery, in particular to a shallow sea chemical pipeline gallery structure. Background Art

[0002] Pipeline gallery, that is, corridor for pipelines, is the main place for concentrated laying of pipelines in large-scale installations. Pipeline gallery is composed of columns, beams and trusses of steel structure or reinforced concrete structure, and can be divided into single-layer or multi-layer, passable or impassable, above ground or underground, etc. Many pipelines in chemical and related factories are concentrated together and arranged along the outside of the equipment or factory buildings, usually in the air, supported by brackets, forming a corridor-like appearance. When chemical pipelines need to cross the sea, pipeline gallery is generally laid on the seabed, and sometimes the pipeline gallery is erected on the surface of shallow sea. When erecting the pipeline gallery on the surface of shallow sea, it is necessary to first erect columns on the sea, then erect the pipeline gallery on the top of the columns, and lay the chemical pipeline in the pipeline gallery. Since there is a certain distance between the pipeline corridor located in the shallow sea and the coast, it is difficult to maintain and inspect the chemical pipelines in the shallow sea pipeline corridor every time. Maintenance personnel need to walk a long distance on the pipeline corridor or take a boat to reach the designated location of the shallow sea pipeline corridor to complete the operation. Walking on the pipeline corridor is not only time-consuming and laborious, but also inefficient; taking a boat to reach the designated location is not only not conducive to a comprehensive inspection of long-distance chemical pipelines, but the cost of maintaining chemical pipelines by boat is relatively high.

[0018] Implement the shallow - sea chemical industrial pipe gallery structure of the present invention. Apply anti - corrosion materials to the outer surfaces of multiple legs 16. Set the multiple legs 16 coated with anti - corrosion materials at intervals in the shallow - sea area, so that the lower ends of the multiple legs 16 are inserted into the seabed and the upper ends of the multiple legs 16 are exposed above the sea surface. Set a square pipe box 11 with the required length at the tops of the multiple legs 16. Apply anti - corrosion materials to the inner and outer walls of the square pipe box 11. After winding anti - corrosion cold - wrapped tapes around the outer surfaces of two pipes B13 with appropriate lengths, insert them into the square pipe box 11 and fix them to the opposite sides at the bottom of the pipe cavity 10 with multiple anti - corrosion - coated clamps B12 arranged at intervals. After winding anti - corrosion cold - wrapped tapes around the outer surfaces of appropriate - length pipes A3 with a quantity suitable for the load - bearing capacity of the square pipe box 11, insert them into the square pipe box 11 and fix them to the opposite side walls of the pipe cavity 10 with multiple anti - corrosion - coated clamps A2 arranged at intervals. Fix the "L" - shaped support bar 8 extending along the length direction of the square pipe box 11 by a method of using multiple screws to pass through the through - holes arranged at intervals on the fixing bar 7 and then fixedly connecting to the screw holes arranged at intervals at the top of the pipe cavity 10. Set two grooves 17 extending along the length direction of the square pipe box 11 at intervals at the middle position of the bottom of the pipe cavity 10. Open a maintenance opening at each interval on the square pipe box 11 and build a passage that can be boarded by a ship into the pipe cavity 10; When it is necessary to repair the pipes A3 and B13 by riding on the electric trolley 9, hook the hanging wheel 18 on the "L" - shaped support bar 8, so that the bottom of the convex spherical surface 46 contacts the concave arc groove 47, the running wheels 35 ride on the two grooves 17, and the two auxiliary wheels 42 respectively ride on the two grooves 17 located in front of and behind the running wheels 35; Combined with the attached Fig. 9When the operator 48 needs to conduct a long-distance inspection of pipeline A3 and pipeline B13, the operator 48 sits on the seat cushion 23 facing the direction of travel, holds the two vertical rods of the "冂"-shaped handrail 21 with both hands respectively, steps on the top of the "L"-shaped pedal 36 on one side of the advancing direction of the box body 25 with both feet, presses the key switch 22 for controlling forward movement. The key switch 22 controls the rotation of the motor 26, drives the spline A30 to rotate, the spline A30 drives the spline B31 to rotate, and further drives the traveling wheels 35 to rotate, driving the electric trolley 9 to move forward. The setting of the two auxiliary wheels 42 prevents the electric trolley 9 from swinging back and forth during forward movement. The top of the electric trolley 9 is limited by the convex spherical surface 46 and the concave arc groove 47, and the bottom is limited by the two trough bodies 17 to prevent the electric trolley 9 from swinging left and right during forward movement. The sliding rod 37 can slide in the shaft hole A44. A spring 38 is sleeved outside the sliding rod 37 between the "冂"-shaped support frame 40 and the "L"-shaped pedal 36, playing a role in damping during slight swinging. The sliding rod 37 can rotate in the shaft hole A44, which plays a role when the square pipe box 11 needs to turn during construction. The two auxiliary wheels 42 can make appropriate rotations according to the turning radian of the two trough bodies 17 (since there is no non-transition right-angle turn when laying chemical pipelines in the shallow sea for the square pipe box 11, the two trough bodies 17 will not have a situation where the two auxiliary wheels 42 are stuck due to a right-angle turn). When reaching the part that needs to be detailedly repaired, press the key switch 22 to stop the electric trolley 9, and then conduct a detailed inspection of pipeline A3 and pipeline B13; When the operator 48 finishes the inspection according to the above steps and needs to return, or when the operator 48 needs to conduct a long-distance inspection of pipeline A3 and pipeline B13 in the opposite direction, the operator 48 sits on the seat cushion 23 facing the opposite direction of the above direction, steps on the top of the "L"-shaped pedal 36 on the other side with both feet, presses the key switch 22 for controlling forward movement in the opposite direction, and the electric trolley 9 can move forward in the opposite direction until the operator 48 presses the key switch 22 for controlling stop after reaching the destination; An electric trolley 9 can be set at intervals in the pipe cavity 10 according to needs to achieve full-coverage inspection of the shallow sea pipe gallery, so as to solve the drawback that it is not easy to conduct detailed inspection due to the long distance between the offshore chemical pipeline and the shore.

A sliding rod (37) extending downward is arranged at the middle position of the bottom of the "L"-shaped pedal (36). The lower end of the sliding rod (37) passes through the shaft hole A (44). A stop head (39) is arranged at the lower end of the sliding rod (37). The sliding rod (37) can rotate and slide in the shaft hole A (44). A spring (38) is sleeved outside the sliding rod (37) between the "冂"-shaped support frame (40) and the "L"-shaped pedal (36). The auxiliary wheels (42) are fixedly sleeved on the wheel shaft B (43) by means of perforations penetrating between the centers of the two bottom surfaces. The auxiliary wheels (42) are located between the two arms of the "冂"-shaped support frame (40). The two ends of the wheel shaft B (43) pass through the two shaft holes B (45) and are rotatably connected to the two shaft holes B (45). Collars B (41) are arranged at both ends of the side wall of the auxiliary wheels (42). The lower ends of the two collars B (41) are both placed in the two trough bodies (17). The bottom of the auxiliary wheels (42) between the two collars B (41) is in contact with the bottom of the lumen (10) between the two trough bodies (17). Both of the two traveling auxiliary mechanisms (14) are fixedly connected to the opposite ends of the box body (25) by means of the outer side walls of the "L"-shaped pedals (36) provided thereon.

10. The shallow sea chemical pipeline gallery structure according to claim 1 is characterized by: The square tube box (11), the supporting legs (16), the clamp A (2), the fixed support vertical rod (1), the fixed support horizontal rod (4), the "L"-shaped support rod (5) and the clamp B (12) are all metal structures.
