FIG. 1 is a schematic illustration of a wellbore maintenance construction platform according to an embodiment of the present invention; FIG. 2 is a top view of a wellbore maintenance construction platform according to an embodiment of the present invention; FIG. 3 is a schematic diagram of a retracted configuration of a mobile stent according to an embodiment of the present invention;
as shown in fig. 1, 2 and 3, the shaft maintenance construction platform provided by this embodiment may be used for shaft maintenance and repair, and may also be used as a repair platform installed on the upper portion of other cages.
This embodiment includes platform support 1 and can dismantle the landing slab 2 of setting in platform support 1 top, and platform support 1 includes two at least movable support 3, and movable support 3 evenly sets up side by side at a side edge at cage 12 top, and movable support 3 can stretch out and retrieve for the top edge. When the movable support 3 extends out, the platform plate 2 is laid on the part extending out of the top of the cage for workers to stand. The number of the movable supports 3 is determined according to the construction specific situation.
The movable support 3 comprises a support column 4, a sleeve 5 is vertically connected to the upper end of the support column 4, the support column 4 can be a cylindrical steel pipe, the sleeve 5 can be a steel pipe with a rectangular longitudinal section, and the middle of the wider side face of the sleeve 5 is welded with the upper port of the support column 4. In order to firmly weld the sleeve 5 and the support pillar 4, reinforcing ribs 9 are uniformly arranged at the connecting circumference of the support pillar 4 and the sleeve 5.
In order to facilitate the movable support 3 to extend out of the top of the cage, a support rod 6 is arranged in the sleeve 5 in a penetrating mode, the support rod 6 can be made of channel steel or steel pipes, and the support rod 6 is matched with the inside of the sleeve 5. In order to prevent the support column 4 from sliding out of the sleeve 5, baffles 7 are arranged at two ends of the support rod 6, and the area of each baffle 7 is larger than that of the end part of the support rod 6. When the support column 4 extends out of the top of the cage in the sleeve 5 or the support column 4 is recovered from the sleeve 5 to the inner side of the top of the cage, the baffle 7 plays a limiting role.
The support column 4 welds the position that is close to the edge in one side at cage 12 top side by side evenly, and for support column 4 welding is firm, the circumference department is connected evenly to support column 4 and cage 12's top is provided with the strengthening rib. The sleeve 5 should be inside the rim, preferably not protruding from the rim. The length of the support rod 6 is determined according to the specific construction situation, and in order to ensure the bearing of the support rod 6, the length of the support rod 6 is x, wherein x is more than 3 times of the length of the sleeve and less than 5 times of the length of the sleeve. The height of the supporting column 4 can be determined according to the condition of the top of the cage, and the movement of the supporting rod is not influenced.
The platform plate 2 is used for standing construction of workers. When the shaft needs to be maintained, the supporting rod 6 of each movable support 3 extends out of the cage, and the upper side surface of the part, extending out of the sleeve 5, of the supporting rod 6 is evenly provided with an internal thread hole along the axis direction. The landing slab 2 tiles in all 6 tops of bracing piece, is provided with the through-hole corresponding with every screw hole on landing slab 2, and the bolt 8 that landing slab 2 passes through in the through-hole is installed in 6 tops of bracing piece. The support bars 6 support workers on the deck plate 2 and the deck plate. The platform plate can be a patterned steel plate or a wood plate.
In order to further increase the safety, a guardrail 10 is connected to one end of the support bar 6 facing the outside of the cage, the guardrail 10 comprises a rectangular frame, the width of the rectangular frame is the same as that of the support bar 6, and the width side of the rectangular frame is mounted at the upper side end of the support bar 6 through bolts. Protective ropes can be connected between the guardrails on the adjacent support rods 6 to prevent workers from falling from the platform.
After the shaft is maintained, the support rod 6 is recovered to the top of the cage. In order to prevent the support rod 6 from sliding outwards in the running process of the cage and colliding with the cage guide beam or the wind and water pipeline. If support column 4 is the channel-section steel, retrieve the back completely to the cage inboard at bracing piece 6, stretch out the side of going up of sleeve pipe part and close to sheathed tube position and be provided with the internal thread hole, twist limit bolt 11 in the internal thread hole. The sleeve 5 is limited between the baffle 7 and the limit bolt 11, and the support rod 6 cannot move.
If the support column 4 is a steel pipe, the support rod 6 can extend out of the horizontal side face of the sleeve 5 part after being completely recovered towards the inner side of the cage, a through hole is formed in the position close to the sleeve 5, and bolt and nut combinations are arranged at two ends of the through hole. The sleeve 5 is constrained between the stop 7 and the bolt and nut combination and the support bar 6 does not move.
At the well casing wall that needs to maintain, this pit shaft maintenance construction platform all needs to be installed to cage top edge that closes on, and the support column of attention every construction platform can not contradict each other after retrieving during the installation.
The use process comprises the following steps:
when beginning the pit shaft maintenance, personnel get into cage top canopy below, at this moment every support column of this construction platform is retrieved in cage top, and the cage is slowly transferred to operating position, dismantles spacing bolt, and every support column stretches out the cage top, and the mounting platform board, constructor can carry out the operation under the condition of effective protection.
When the cage needs to be moved to the next working point, personnel enter the lower part of the rain shelter, the platform plates are disassembled, each supporting column is recovered, the limiting bolts are arranged, and the cage is prevented from colliding with the cage guide beam or the wind-water pipeline during operation.
When personnel need to rise the well in the pit, can easily withdraw every support column at any time, can use the cage to carry out personnel's transport immediately.
The construction platform is fast and reliable, the problem that normal operation of the cage is hindered when a shaft is maintained is effectively solved, the extendable and retractable construction platform guarantees the operation range of shaft maintenance, and construction is safe and reliable.
