When danger occurs during the operation, personnel need to evacuate from the drilling platform quickly. At present, the drilling platform is equipped with a set of escape devices welded with steel structural parts, which are connected to the drilling platform with pins. The length is more than 5 meters. When the height of the drilling platform is 12.5 meters, the length of the escape chute is about 15 meters and the weight is about 2 tons. During the on-site installation operation, the escape chute is hoisted by a crane. After the overall hoisting and installation is flush with the drilling platform surface, the escape chute is connected to the drilling platform with pins. There are risks such as the angle of the hoisting wire rope is too large, the length is too long, the pin is inconvenient to install, and personnel are working at high places near the edge. In the case of restricted well sites, the escape chute cannot be installed due to its long length, which does not meet the requirements for rapid escape of personnel. Utility Model Content

When escaping, personnel enter the inner layer of the cylindrical escape device and slide to the ground using the high sliding properties of the anti-static inner sliding layer and the body's own weight. The damping effect of the high-elasticity and high-strength middle layer creates lateral resistance to the sliding personnel to slow down the sliding speed and allow the sliding personnel to land safely. The outer protective layer is mainly used to protect the middle layer and inner layer of the escape device to avoid damage to the middle layer and inner layer during transportation and folding. At the same time, in the event of a fire at the wellhead, it prevents high temperature from damaging the escape device and protects the inner layer personnel from burns.

[0013] Reference Figure 1-4 As shown, a drilling platform escape device is used for oil and gas drilling or well repairing drilling platforms, including a release device 1 and a flexible escape slide 2. The release device 1 includes an escape platform 4 and a built-in power source 3. The escape slide 2 is arranged on the escape platform 4. The built-in power source is used to drive the escape platform to lie flat, and then release the escape slide. The escape slide is a three-layer composite cylindrical structure, the outer layer is a flame retardant protective layer 5, the middle layer is a buffer layer 6, and the inner layer is an anti-static inner sliding layer 7. A sinker 8 is provided at the bottom of the escape slide, as shown in FIG. Figure 1 and Figure 2 As shown, the escape slide is folded and stored on the escape platform when not in use.

[0014] The release device adopts a box-type structure, and a release button is arranged on the outside of the release device. The built-in power source is connected with a flip structure, and the flip structure is used to drive the release device to flip, so that the escape platform is turned from a vertical state to a horizontal state.

[0015] like Figure 1 and Figure 3As shown, the release device is arranged at the edge of the drilling platform 10 and is flipped to the outside of the drilling platform when in use. In one embodiment, the built-in power source drives the electric cylinder, which is arranged on both sides of the release device, and the release device is flippable and hinged to the drilling platform. After pressing the release button, the electric cylinder drives the release device to flip, and the escape platform is turned from a vertical state to a horizontal state, and the escape slide is unfolded under the gravity of the sinker.

[0016] There are quick-hanging ears at the end of the escape slide, and protective devices are installed on the escape platform to prevent people from falling. Figure 3 As shown, in one embodiment, one side of the release device is a personnel evacuation passage, and the other three vertical sides perpendicular to the escape platform are closed with warning railings 9 to prevent people from falling in a tense situation. The platform has sufficient strength to withstand the falling force generated by an adult man escaping. The escape device is a box-shaped body with the same height as the rig floor railing, which is set at the edge of the rig or workover rig rig, embedded in the opening of the rig floor railing near the wellhead for escape, and connected to the railing as a whole, meeting the requirements of the rig floor railing closure.

[0017] In one embodiment, the middle layer is made of high-elasticity and high-strength materials. When escaping, people enter the cylindrical escape slide and use the high sliding properties of the anti-static inner sliding layer and the body's own weight to slide to the ground. The damping effect of the high-elasticity and high-strength middle layer produces lateral resistance to the sliding person to slow down the sliding speed, allowing the sliding person to land safely. The outer flame-retardant protective layer is mainly used to protect the middle layer and inner layer of the escape slide to avoid damage to the middle layer and inner layer during transportation and folding. At the same time, in the event of a fire at the wellhead, it prevents high temperature from damaging the escape device and protects the inner layer personnel from burns.

[0018] The length of the escape chute matches the height of the drilling platform, the end of the escape chute is no more than 1 meter above the ground, and a buffer pad is provided on the ground. Preferably, a quick hanging ear that can be connected to a ground anchor is provided at the end of the escape chute. When the escape device needs to be tilted at a certain angle, two ground anchors are set on the ground. After the escape device is lowered, the hanging ear is connected to the ground anchor to form an escape passage with a certain inclination.

[0019] Obviously, the escape slide of the utility model can also remove the release device, and directly install the escape slide at the escape point of the drilling platform, and use it directly when personnel need to evacuate quickly. The escape device can be configured on the drilling rig and workover rig for use alone, or a set of flexible escape device can be added on the basis of the existing steel escape slide. It is also possible to configure 1-2 sets of flexible escape devices around the drilling platform of a drilling rig or workover rig to meet the needs of rapid escape of personnel on the drilling platform.

[0020] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model are included in the protection scope of the utility model.
