Abstract
A kind of push rod damp slow falling device is mainly made of descending lifeline shell, push rod, cylinder, rotating wheel, end cap, slow descending rope and bolt etc..Cylinder is mounted in push rod, and push rod is arranged in rotating wheel, and rotating wheel is arranged in descending lifeline shell.The arc-shaped ring gear of one odd number tooth of setting in descending lifeline shell.Slow descending rope drives rotating wheel rotation, push rod to be moved back and forth in the gear ring effect lower edge rotation wheel radial of descending lifeline shell when descending lifeline works, and cylinder is pushed to be close to the flank of tooth rotation of gear ring.Gear ring acts power to cylinder, and active force is transmitted to rotating wheel by cylinder, and rotating wheel acquisition rotates the opposite opposing torque in direction, to make the people or object of slow drop achieve the purpose that the slow drop of speed limit.The descending lifeline is reasonable for structure, security and stability is high, is not afraid of that oily, not afraid of water, manufacturing cost is low.
Description
Technical field
The present invention relates to a kind of devices declining people or object by eminence speed limit, belong to fire-extinguishing and lifesaving equipment.
The existing device for declining people or object by eminence speed limit, there are many used technology type, but all or it is more or
Exist less complicated, manufacturing cost is high, security and stability difference and it is inconvenient to use the defects of.
Invention content
The technical problem to be solved by the present invention is to：A kind of push rod damp slow falling device is provided in view of the deficiencies of the prior art.
The technical solution adopted in the present invention is：Push rod damp slow falling device mainly by descending lifeline shell, push rod A, push rod B,
Cylinder, rotating wheel, end cap, slow descending rope and bolt are constituted.Slow descending rope is wrapped in the shaft of rotating wheel, and one end of slow descending rope connects
Connect must slow drop people or object, two orthogonal through-holes are radially set on the runner of rotating wheel, install respectively push rod A and
Push rod B, rotating wheel are mounted in descending lifeline shell, the arc-shaped ring gear of one odd number tooth of setting in descending lifeline shell, should
Gear ring can be made of one with descending lifeline shell, can also use the material different from descending lifeline shell, such as：It is non-using nylon etc.
Abrasion-resistant metal, impact-resistant material.U-shaped groove is respectively set in the both ends of push rod A and push rod B, and a circle is arranged in each U-shaped groove
Cylinder.Thereby, slow descending rope drives rotating wheel rotation when delaying the people dropped or object decline, and the cylinder of push rod one end is in descending lifeline
The gear ring effect of shell is lower to push push rod to be moved radially towards the other end along rotating wheel, and other end cylinder is made to be close to the tooth of gear ring
Face rotates, and since the number of teeth of gear ring is odd number, the cylinder at both ends alternately pushes push rod to move back and forth so that the circle at push rod both ends
Cylinder is all close to the flank of tooth rotation of gear ring, and gear ring acts power to cylinder, which increases with cylinder speed of moving body
And increase, active force is transmitted to rotating wheel by cylinder, and rotating wheel is obtained to be increased and increased opposing torque with rotary speed, when
When opposing torque is equal to the forward torque that human body generates rotating wheel, people or object decrease speed is not further added by, permanent to reach
The slow drop purpose of speed.
The push rod A of push rod damp slow falling device is provided with through-hole, and push rod B can be slided in through-hole, so that push rod damps
Descending lifeline more compact structure.
The push rod A of push rod damp slow falling device, the distance of center circle of the U-shaped bottom portion of groove circular arc in the both ends push rod B and cylinder
The sum of diameter is more than the arc-shaped ring gear tip diameter of descending lifeline, less than being averaged for tip diameter and root diameter
Value.
The cylinder of push rod damp slow falling device can rotate in the U-shaped groove of push rod A and push rod B, reduce cylinder with this
Frictional force.
Description of the drawings
Fig. 1 and Fig. 2 is a preferred embodiment of the present invention structure sectional view.
Specific implementation mode
Referring to Fig. 1 and Fig. 2 the push rod damp slow falling device mainly by descending lifeline shell 1, push rod A2, push rod B3, cylinder 4,
Rotating wheel 5, end cap 6, slow descending rope 7 and bolt 8 are constituted.Slow descending rope 7 is wrapped in the shaft of rotating wheel 5, and one end of slow descending rope 7 connects
Connect must slow drop people or object, the radial two orthogonal through-holes of setting of the runner of rotating wheel 5, install respectively push rod A2 and
Push rod B3, rotating wheel 5 are mounted in descending lifeline shell 1, the arc-shaped ring gear 9 of one 15 tooth of setting in descending lifeline shell 1,
U-shaped groove is respectively set in the both ends of push rod A2 and push rod B3, and each a cylinder 4 is arranged in U-shaped groove.
