Description

Technical Field

[0001] The utility model relates to the technical field of anti - falling devices for casing centralizing platforms, and particularly relates to a novel anti - falling protection device for the body of a casing centralizing platform. Background Technique

[0002] The casing centralizing platform is a commonly equipped device in a drilling rig, and its function is to be an operating platform for an operator to centralize the casing when conducting the casing - lowering operation during the drilling process. The position of the body of the operating platform needs to be adjusted up and down according to the actual situation on site. The body is lifted and lowered by wire ropes. To prevent accidents caused by the breakage of the wire ropes resulting in the fall of the body, the commonly used anti - falling safety device currently adopts a spring to pull a toothed plate, so that the toothed plate extrudes the two - side tracks, thereby generating a large frictional force to hold the body and prevent the body from falling. The so - called toothed plate is processed into a form with sawteeth at the end to improve the frictional contact form with the track and increase the reliability. However, when using this protection device, due to the high processing progress requirements in the manufacturing process of the toothed plate, it will cause high production costs. In addition, during the process of using the toothed plate for anti - falling for a long time, the sawteeth between the toothed plates will be worn, affecting the service life of the toothed plate and increasing the hidden threat of the toothed plate. Therefore, it is necessary to design a reliable safety device. On the premise of eliminating the anti - falling safety device, while taking economy into account, when the wire rope breaks, the safety device can lock the body, thereby preventing the body from falling and protecting the safety of the equipment and operating workers.

Embodiment

[0019] This embodiment provides a novel anti-falling protection device for the body of a casing centralizer platform. Referring to the appendix Figure 1 The device includes a body 1, ear seats 2, and a stretching device 6. An ear seat 1 is provided on the upper surface of the body 1. The ear seats 2 are symmetrically arranged at both ends of the upper surface of the body 1. A locking plate 7 is provided inside the upper part of the ear seat 2. The middle of the locking plate 7 is rotationally connected to the ear seat through a rotating shaft and a rotating hole. Long strip hole plates 3 are symmetrically arranged in the middle of the upper surface of the body 1. A pulley group 5 is arranged between adjacent long strip hole plates 3. A hole 301 is provided on the upper side surface of the long strip hole plate 3. A pulley rod 4 is installed inside the hole 301. Along the height direction of the long strip hole plate 3, the height of the hole 301 is 2 to 3 times the diameter of the pulley rod 4. Preferably, in this embodiment, the height of the hole 301 is 2.5 times that of the pulley rod 4. The pulley rod 4 is used in cooperation with the pulley group 5. The pulley rod 4 penetrates through the hole 301 and extends out of the long strip hole plate 3. The length of the pulley rod 4 is longer than the interval length between adjacent long strip hole plates 3. In addition, a blocking strip 8 is provided on the extended part of the pulley rod 4. The blocking strip 8 is specifically arranged outside the long strip hole plate 3 to fix the position of the pulley rod 4.

[0020] A stretching device 6 is also provided at the bottom of the extended pulley rod 4. The stretching device 6 is specifically installed between the ear seat 2 and the long strip hole plate 3. The stretching device 6 includes a fixed hook lock 601 and a spring 602. The bottom of the fixed hook lock 601 is fixedly installed on the upper surface of the body 1, and its top is fixedly connected to one end of the spring 602. The other side of the spring 602 is connected to the bottom of the pulley rod 4.

[0021] Referring to the appendix Figure 3, a lug 701 is provided on one side of the locking plate 7, and a U-shaped seat 9 is fixedly provided on the other side. A circular hole is provided on the side surface of the U-shaped seat 9. The U-shaped seat 9 is hinged to both sides of the pulley rod 4 through the circular hole. A slot 10 is also installed on the outer side surface of the table body 1, and a rotational connection is provided between the slot 10 and the lug 701.

[0022] Refer to the appendix Figure 1 , appendix Figure 2 and appendix Figure 3 , when the device is working normally, a steel wire rope is installed on the pulley block 5. Due to the pulling of the steel wire rope, the pulley block 5 and the pulley rod 4 are located at the uppermost part of the hole 301 at this time, and the locking plate 7 is in a contracted state at this time. When the steel wire rope breaks, due to the disappearance of the pulling force of the steel wire rope, at this time, due to the existence of the pulling force of the spring 602, the spring 602 contracts, driving the pulley block 5 and the pulley rod 4 to move downward. The pulley rod 4 can rotate with the U-shaped seat 9, and the U-shaped seat 9 drives the locking plate 7 to rotate. The locking plate 7 rotates around the rotating shaft, the locking plate 7 extends out, and inserts the lug 701 into the slot 10 to complete the locking and prevent the platform from continuing to fall.

[0023] In summary, the present utility model effectively prevents the table body from falling during work by providing an ear seat, a stretching device and a long hole plate above the table body, installing a rotatable locking plate above the ear seat, and setting the height of the hole in the long hole plate to be greater than the diameter of the pulley rod. While taking into account economy, it effectively protects the table body equipment itself.

[0024] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
