Description

Technical Field

[0001] The utility model relates to the field of high-rise fire rescue, in particular to a rescue cabin brake release pull rod structure used in a high-rise escape device. Background Art

[0002] With the acceleration of urbanization and the increasing number of high-rise buildings, the problem of evacuating people in emergency situations such as high-rise fires and earthquakes has become increasingly prominent. Existing high-rise escape devices have largely alleviated such risks, but there are still certain limitations and safety hazards. Traditional high-rise escape devices are usually equipped with a sophisticated braking system, which interacts with the high-strength steel wire rope that controls the rise and fall of the rescue capsule to ensure that the rescue capsule can stop stably when it reaches the top of the building, and releases the brakes when necessary, allowing the rescue capsule to descend smoothly along the preset guide rails.

[0003] Existing brake release methods mostly use a pull rod structure, that is, manually pulling the pull rod located outside the lifeboat to release the lock of the brake device on the wire rope, thereby starting the lifeboat's descent process. However, in actual applications, especially in extreme emergency situations, such as when there is only one person left on the roof to be rescued, the trapped person must risk leaving the relatively safe interior of the lifeboat and stretching out his body to operate the pull rod structure, which not only greatly increases the difficulty of operation, but also significantly increases the risk of accidental injury, and in severe cases may even lead to escape failure.

[0004] Therefore, it is imperative to design a brake release rod structure for a lifeboat cabin used in a high-rise escape device. Utility Model Content

[0005] In view of the defects of the above-mentioned prior art, the utility model provides a lifeboat brake release rod structure used in a high-rise escape device, aiming to solve the problem of increased difficulty in operation for escapees and increased risk of accidental injury due to the need for external operation of the brake release rod in the prior art of high-rise escape devices.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a lifeboat brake release rod structure applied to a high-rise escape device, comprising a rod body assembly, a positioning rod, a counterweight block and a latch, wherein the rod body assembly is hinged on the inner frame of the escape device, the rod body assembly is connected to the counterweight block by a short steel chain, the counterweight block is connected to the positioning rod by a long steel chain, and the latch is arranged on one end of the long steel chain close to the counterweight block; in an unactivated state, the counterweight block is fixed to the latch positioning assembly of the outer frame of the escape device by the latch, and the positioning rod is embedded in a positioning rod snap-in block adjacent to the latch positioning assembly; when the rod structure is pre-activated, the positioning rod is taken out of the positioning rod snap-in block and hoisted on the lifeboat below the outer frame.

[0007] Based on the above, the beneficial effect of a lifeboat brake release rod structure applied to a high-rise escape device is to solve the problem of increased difficulty in operation and increased risk of accidental injury for escapees caused by the need for external operation of the brake release rod in the high-rise escape device in the prior art; it is mainly reflected in: the utility model changes the original method of requiring external direct operation of the rod, and instead utilizes a mechanical linkage structure of the rod main body assembly, etc., so that the escapee can indirectly control the brake release process inside the lifeboat, which significantly reduces the difficulty of operation and reduces the risk of accidental injury caused by improper external operation; the beneficial effect of the rod main body assembly is to ensure that the user can control the brake release in the lifeboat; the beneficial effect of the positioning rod is to quickly transfer to the lifeboat in the pre-activated state, so that the user can easily release the brake after picking it up and pulling it in the lifeboat movement; the beneficial effect of the counterweight block is to use its own weight to assist the movement of the pull rod structure, ensuring that the brake release action can be easily achieved; the beneficial effect of the pin is to play a locking and unlocking role, ensuring the safe fixation of the counterweight block when the pull rod structure is not activated; the beneficial effect of the inner frame is to install the pull rod main body assembly; the beneficial effect of the short steel chain and the long steel chain is to form a flexible mechanical conduction chain to ensure the effective transmission of force and the smooth progress of the brake release action; the beneficial effect of the outer frame is to provide a support for the positioning and locking of the counterweight block; the beneficial effect of the latch positioning assembly is to accurately position and fix the counterweight block, which is convenient for quick unlocking before the brake is released; the beneficial effect of the positioning rod card block is to ensure that the positioning rod is firmly stored when it is not activated, and does not interfere with the normal use of the escape device; the beneficial effect of the lifeboat is to enable personnel to descend smoothly to the ground.

[0008] Furthermore, the pull rod main body assembly includes a first pull rod, a second pull rod and a hinged action limiting component, one end of the first pull rod is hinged to the inner frame, one end of the second pull rod is hinged to the other end of the first pull rod, the other end of the second pull rod is provided with an L-shaped suspension rod, the L-shaped suspension rod is fixedly connected to one end of the short steel chain, and the hinged action limiting component is used to limit the rotation range of the first pull rod.

[0009] Based on the above, the beneficial effect of the first pull rod and the second pull rod is that they together constitute a brake release activity mechanism through hinged linkage; the beneficial effect of the hinged action limiting component is to prevent excessive pulling of the brake assembly from causing equipment damage or misoperation; the beneficial effect of the L-shaped hanger is to ensure that the pull rod action can be effectively converted into the force required for brake release and to install one end of the short steel chain.

[0010] Furthermore, the articulated action limiting component is composed of a limiting block and a limiting pin, the limiting block is arranged on the inner frame and is located above the first pull rod, the limiting pin is threadedly connected to the limiting block, and a limiting gasket is arranged on the upper outer end of the hinged part of one end of the inner frame near the first pull rod.

In the unactivated state, the upper end of the counterweight block is sleeved on the bending part of the bending tube, and the latch passes through the first latch ear, then passes through the long steel chain, and finally passes through the second latch ear to lock the counterweight block.

[0013] Based on the above, the beneficial effect of the latch positioning block is the installation of the bent tube; the beneficial effect of the bent tube is the installation of the counterweight block; the beneficial effect of the latch ear is: by inserting the latch, the strength coordination between the latch, the long steel chain and the latch ear is enhanced to ensure a secure lock.
