Description

TECHNICAL FIELD

[0001] The utility model relates to fire fighting equipment technical field more specifically, it relates to a fire fighting reel stand. BACKGROUND

[0002] In the current fire fighting equipment field, fire fighting reel stand as a kind of key emergency equipment, plays an important role in fire prevention and emergency rescue, however, the existing fire fighting reel stand technology still has many deficiencies, these problems not only influence the use efficiency of equipment, also possibly causes unnecessary delay under emergency.

[0003] First, the fire fighting reel stand in prior art has obvious human consumption problem in the use process, when needing to use fire hose, operator usually needs to manually quickly pull out hose, and the pipe collection process after use, operator needs to manually rewrap hose on the outside of reel stand, this is a time-consuming and labor-consuming work, under the tired state after fire, this physical labor not only increases the burden of fire personnel, also possibly causes hose damage or unevenly reeling due to improper operation, this manual operation mode not only reduces overall work efficiency, also possibly influences equipment preparation state when next emergency use.

[0004] Second, the structure design of existing fire fighting reel stand is too simple, lacks necessary functional components, which leads to a series of use problems, the most prominent problem is that the stability of hose after reeling is insufficient, due to lack of effective fixing mechanism, fire hose after reeling is prone to loose, this looseness not only influences the neatness and storage effect of equipment, more importantly, possibly causes hose entanglement or drop under emergency, seriously influences use efficiency, another significant problem is lack of limiting control to reel stand in the use process, when operator pulls out fire hose to a certain length, due to lack of suitable brake or limiting device, reel stand can continue to rotate, leading to excessive hose to be released, this condition not only causes hose redundancy, increases operation difficulty, also possibly leads to that hose forms dangerous tripping hazard on ground, especially in the fire environment of poor visibility, these problems seriously reduce the use effect and reliability of fire fighting reel stand.

[0005] In addition, the existing fire reel rack has poor control performance during hose winding, which is mainly manifested in the lack of effective limiting and guiding structure for the fire hose. During winding, due to the lack of a suitable guiding mechanism, the hose is prone to looseness, deviation or superposition, which not only affects the efficiency of winding, but also may cause uneven distribution of the hose on the reel. Uneven winding may cause local pressure on the hose, which may cause deformation or damage to the hose in the long term. More seriously, loose winding may cause the hose to be tangled or knotted during the next use, which may cause fatal delay in emergency situations. In addition, due to the lack of a pressing mechanism, even after the initial winding is completed, the hose may not be tightly attached to the outside of the reel rack. This loose state not only increases the occupied space of the equipment, but also may cause the hose to loosen or fall off during storage. In the long term, this improper winding and storage method will also accelerate the aging and damage of the hose, increasing the maintenance cost and replacement frequency of the equipment.
