Description

Technical Field

[0001] This utility model relates to the field of security facilities technology, specifically to an emergency buffer device for preventing falls from drilling platforms. Background Technology

[0002] Drilling platforms are offshore structures primarily used for drilling wells. They are equipped with drilling, power, communication, and navigation equipment, as well as safety, rescue, and living facilities for personnel. They are an indispensable means for offshore oil and gas exploration and development.

[0003] Drilling platforms are primarily steel structures. Because they are located offshore, fall arrest nets are typically installed around the platform to prevent personnel from falling. Currently, most fall arrest devices used on drilling platforms are similar in structure, usually consisting of extended supports and fall arrest nets. The nets are secured to the supports to catch falling personnel. However, in actual use, some functional shortcomings exist, leaving room for improvement. For example, fall arrest nets are generally made of nylon or wire mesh, directly catching falling personnel. When a worker falls, the nets tighten instantly under stress, and a significant portion of the impact from the fall is still returned to the person. There is room for further improvement in impact reduction; they lack additional cushioning capabilities.

[0004] Now, a novel emergency buffer device for preventing falls from drilling platforms is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an emergency buffer device for preventing falls from drilling platforms, so as to solve the problem mentioned in the background art of not having further buffering function.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an emergency buffer device for preventing falls on drilling platforms, comprising a main support frame, two sets of brackets arranged above the main support frame, multiple sets of hanging rings welded to the front and rear ends of the brackets respectively, a fall-prevention rope net arranged between the two sets of brackets, D-shaped hooks movably connecting the hanging rings and the fall-prevention rope net, a support plate fixedly connected to the top of the bracket, a soft rubber sleeve glued to the top of the support plate, the soft rubber sleeve being filled with soft foam, and a buffer component for further mitigating impact at the top of the main support frame.

[0007] The buffer assembly includes multiple sets of fixed cylinders, which are respectively fixedly connected to the interior of the front and rear ends of the top of the main support frame. The top of each fixed cylinder is threaded with an internal threaded fixing cap. Multiple sets of extension rods are vertically welded to the bottom of the bracket. A fixing ring is welded to the outside of each extension rod, and a spring is sleeved on the bottom of the outside of each extension rod.

[0008] As a further technical solution of this utility model, the top of the internal thread fixing cover is provided with a groove, the inner diameter of which is the same as the outer diameter of the extension rod, and the extension rod can slide up and down along the inside of the groove.

[0009] As a further technical solution of this utility model, the outer diameter of the fixing ring is adapted to the inner diameter of the fixing cylinder, and the fixing ring can slide up and down along the inside of the fixing cylinder.

[0010] As a further technical solution of this utility model, the vertical center lines of the fixed cylinder and the extension rod coincide, and the bottom end of the fixed ring and the top end of the spring are in contact.

[0011] As a further technical solution of this utility model, the left and right sides of the bracket and the tray are flush, and the front and rear ends of the tray and the soft rubber sleeve are flush.

[0012] As a further technical solution of this utility model, a pressure sensor is fixedly connected to the bottom end of the fixed cylinder, a micro controller is fixedly connected to the left side inside the main support frame, an audible and visual alarm is installed on the right side of the micro controller, the top end of the pressure sensor passes through the bottom end of the fixed cylinder and extends into the interior, and the pressure sensor, the audible and visual alarm, and the micro controller are electrically connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the drilling platform fall prevention emergency buffer device not only realizes the function of further buffering, but also realizes the function of shielding and protecting the rope and net connection, and also realizes the function of fall feedback; (1) By setting up a main support frame, a fixed cylinder, an internal threaded fixed cover, an extension rod, a fixed ring, a spring, a bracket, a hanging ring, and a fall protection rope net, when in use, the main support frame is fixed on the drilling platform, and the fall protection rope net is fixed on the hanging ring of the bracket by a D-shaped hook. When personnel fall, they are caught by the fall protection rope net. The fall protection rope net moves downward under force, the bracket moves downward synchronously, the extension rod moves downward along the inside of the fixed cylinder, and the fixed ring moves downward while the spring plays a role in buffering and supporting, further reducing the potential energy of the fall, turning the rigid impact into a flexible impact, reducing the injury to personnel, and realizing the function of further buffering. (2) By setting up a support plate, a soft rubber sleeve, and soft foam, the support serves as the connection node of the fall arrest rope net during use. The support plate covers the top of the support plate, and the soft rubber sleeve on top of the support plate is filled with soft foam, which improves safety performance and at the same time covers the connection point of the rope net. This avoids collisions between personnel and hanging rings and achieves the function of covering and protecting the connection point of the rope net; (3) By setting up a pressure sensor, an audible and visual alarm and a micro controller, when in use, as the extension rod moves down along the inside of the fixed cylinder, the bottom of the extension rod presses against the top of the pressure sensor due to the pressure of the person's own weight. The micro controller senses the pressure signal fed back by the pressure sensor, and the audible and visual alarm immediately sounds an alarm to remind the staff to rescue in time, thus realizing the function of fall feedback.

A buffer component that can further mitigate impact is provided at the top of the main support frame 1. Please see Figure 1-4An emergency buffer device for preventing falls on a drilling platform also includes a buffer assembly. The buffer assembly includes multiple sets of fixed cylinders 2, which are respectively fixedly connected to the interior of the front and rear ends of the top of the main support frame 1. The top of the fixed cylinder 2 is threaded with an internal threaded fixing cap 3. Multiple sets of extension rods 4 are vertically welded to the bottom of the bracket 7. A fixing ring 5 is welded to the outside of the extension rod 4, and a spring 6 is sleeved on the bottom of the outside of the extension rod 4. The top of the internal threaded fixing cap 3 has a slot, the inner diameter of which is the same as the outer diameter of the extension rod 4. The extension rod 4 can slide up and down along the inside of the slot. The outer diameter of the fixing ring 5 is matched with the inner diameter of the fixing cylinder 2. The fixing ring 5 can slide up and down along the inside of the fixing cylinder 2. The vertical center lines of the fixing cylinder 2 and the extension rod 4 coincide. The bottom end of the fixing ring 5 is in contact with the top end of the spring 6, further reducing the downward impact potential energy. Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the fall arresting rope net 9 moves downward under force, the bracket 7 moves downward simultaneously, the extension rod 4 moves downward along the inside of the fixed cylinder 2, and the fixed ring 5 moves downward while the spring 6 plays a role in buffering and supporting, further reducing the potential energy of the fall, turning the rigid impact into a flexible impact, and reducing the injury to personnel.

[0018] The top of the bracket 7 is fixedly connected to the support plate 11, and the top of the support plate 11 is glued with a soft rubber sleeve 12. The soft rubber sleeve 12 is filled with soft foam 13. The left and right sides of the bracket 7 and the support plate 11 are flush, and the front and rear ends of the support plate 11 and the soft rubber sleeve 12 are flush, which covers the rope net connection position and improves safety performance. Specifically, such as Figure 1 and Figure 4 As shown, the soft rubber sleeve 12 at the top of the pallet 11 is filled with soft foam 13 to improve safety performance and at the same time cover the rope net connection to prevent personnel from bumping into the hanging ring 8.

The microcontroller 16 senses the pressure signal fed back by the pressure sensor 14, and the audible and visual alarm 15 immediately sounds an alarm to remind the staff to rescue in time.

[0020] Working Principle: In use, the main support frame 1 is first fixed to the drilling platform. The fall arresting rope net 9 is fixed to the hanging ring 8 of the bracket 7 via D-hooks 10. When a person falls, the fall arresting rope net 9 catches them. The fall arresting rope net 9 moves downward under force, and the bracket 7 moves downward simultaneously. The extension rod 4 moves downward along the inside of the fixed cylinder 2. As the fixed ring 5 moves downward, the spring 6 acts as a buffer and support, further reducing the potential energy of the fall, turning the rigid impact into a flexible impact, and reducing the injury to the person. As the extension rod 4 moves downward along the inside of the fixed cylinder 2, under the pressure of the person's own weight, the bottom of the extension rod 4 presses against the top of the pressure sensor 14. The microcontroller 16 senses the pressure signal fed back by the pressure sensor 14, and the audible and visual alarm 15 immediately sounds an alarm, reminding the staff to rescue in time. The bracket 7 serves as the connection node of the fall arrest rope net 9. It is covered by the bracket plate 11. The soft rubber sleeve 12 on the top of the bracket plate 11 is filled with soft foam 13 to improve safety performance and at the same time cover the rope net connection to prevent personnel from bumping into the hanging ring 8.
