Description

Lifting device for oil storage cavern shaft construction

technical field

The utility model relates to a hoisting device, in particular to a hoisting device for vertical shaft construction of an oil storage cavern.

Background technique

The use of underground caverns to store crude oil has become the development trend of national crude oil reserves in recent years. Most of the currently used oil storage caverns are built along the mountains and enter the mountain through horizontal passages. A shaft is excavated above the cavern. After the construction of the shaft is completed, the horizontal passage is closed. The operation of entering and exiting the oil storage cavern is completed through the shaft. When the shaft is excavated, support construction is required. Due to its narrow internal space, It has a higher height, so it is more difficult to support the shaft. The existing method is to set up scaffolding in the cavern and the shaft, and the construction personnel carry out the shaft support construction on the scaffolding. However, due to the cavern and the The internal space of the shaft is very limited, and the assembly and disassembly of the scaffolding consumes a lot of construction time, and the construction period is long; the second is to use a simple hanging basket to lift the construction personnel and supporting materials from the wellhead, but this construction method is less stable. And there is a certain potential safety hazard when the support material is suspended downward from the wellhead, which will threaten the life safety of the operator in the hanging basket.

Utility model content

In order to achieve the above object, the utility model is realized through the following technical proposals: a shaft is included, a hanging pan and a hanging basket are arranged in the shaft, a lifting passage is provided on the hanging pan, the hanging basket can pass through the lifting passage, and a fixing frame is arranged above the wellhead at the top of the shaft The first fixed pulley, the second fixed pulley and the third fixed pulley are installed on the fixed frame, the first winch, the second winch and the third winch are arranged outside the wellhead at the top of the shaft, and the steel cable of the first winch passes through the first fixed pulley After being connected with the hanging basket, the steel cables of the second hoist and the third hoist pass respectively through the second fixed pulley and the third fixed pulley and are connected with the suspension pan. A self-locking hook is installed at the end of the steel cable of the first winch, and a hanging ring is arranged on the top of the hanging basket, and the self-locking hook matches the hanging ring. A guiding device is provided on the hanging basket. The guide device includes collars arranged on both sides of the hanging basket, each collar is provided with a guide cable, one end of the guide cable is connected to the fixing frame, and the other end of the guide cable is connected to the bottom of the shaft. Guardrails are installed on the suspension plates around the hoistway. A safety rope is arranged on the hanging pan, and the safety rope is connected with the fixed frame.

The utility model has the advantages of high construction efficiency and strong stability, and the supporting parts are hoisted upward from the bottom of the shaft, which can eliminate potential safety hazards in the hoisting process and ensure the safety of construction personnel.

Detailed ways

The hoisting device for the shaft construction of the oil storage cavern described in the utility model includes a shaft 9, and a hanging pan 11 and a hanging basket 23 are arranged in the shaft 9, and a lifting passage 12 is provided on the hanging pan 11, and the hanging basket 23 can pass through the lifting passage 12. , a fixed frame 1 is set above the wellhead at the top of the vertical shaft 9, the first fixed pulley 2, the second fixed pulley 3 and the third fixed pulley 7 are installed on the fixed frame 1, and the first hoist 16 and the second hoist are arranged outside the wellhead at the top of the vertical shaft 9 17 and the third hoist 18, the steel cable of the first hoist 16 passes through the first fixed pulley 2 and is connected with the hanging basket 23, and the steel ropes of the second hoist 17 and the third hoist 18 pass through the second fixed pulley 3 and the second fixed pulley 2 respectively. After the three fixed pulleys 7 are connected with the hanging pan 11. When the utility model is in use, the second hoist 17 and the third hoist 18 are used to lower the suspension pan 11 to the construction height along the shaft 9, and then use the first hoist 16 to lower the hanging basket 23 that the construction personnel rides to the height of the suspension pan 11. After the construction workers enter the hanging pan 11 from the hanging basket 23, the hanging basket 23 descends into the cavern at the bottom of the shaft 9. After the construction personnel in the cavern load the supporting construction materials into the hanging basket 23, the first winch 16 will support the The construction material is lifted to the height where the suspension plate 11 is used for the support construction of the shaft 9. The utility model does not need to set up auxiliary equipment such as scaffolding in the cavern and the shaft 9 during the support construction of the shaft 9, which is conducive to improving the construction efficiency of the shaft support and greatly shortening the construction period of the oil storage cavern. It does not require manned lifting and has strong stability, and the support materials used for construction are lifted upwards from the bottom of the shaft, which can eliminate potential safety hazards in the process of hoisting personnel and construction materials and ensure the safety of construction personnel.

In order to reduce the load of the first hoist 16 when lifting construction materials, the utility model can install a self-locking hook 20 at the end of the steel cable of the first hoist 16, and a hanging ring 21 is arranged on the top of the hanging basket 23, and the self-locking hook 20 and Hanging ring 21 cooperates. This structure can separate the hanging basket 23 from the steel cables of the first hoist 16. After the construction personnel enter the hanging pan 11 from the hanging basket 23, the first hoisting machine 16 will lift the hanging basket 23 to the wellhead at the top of the shaft 9, and the construction personnel at the wellhead will After the hanging ring 21 on the top of the hanging basket 23 is taken off from the self-locking hook 20, the first hoist 16 lowers the self-locking hook 20 to the cavern at the bottom of the shaft 9 to hang construction materials.

The utility model can be provided with guiding device on the hanging basket 23 in order to strengthen the stability when the hanging basket 23 is manned. The guide device of the present utility model can adopt various structures, wherein the preferred structure is: the guide device includes collars 22 arranged on both sides of the hanging basket 23, and guide cables 4 are all set in each collar 22 to guide the One end of the steel cable 4 is connected with the fixed frame 1, and the other end of the guide cable 4 is connected with the bottom of the shaft 9. During use, the guide wire rope 4 is in a tight state, and the collars 22 on both sides of the hanging basket 23 slide along the guide wire rope 4 to guide the hanging basket 23 and prevent the hanging basket 23 from tilting when it is manned.
