Detailed Description
The present application is described in further detail below with reference to the accompanying drawings.
The embodiment of the application discloses high altitude anti-falling net for improving construction safety, as shown in fig. 1 and fig. 2, includes: the anti-falling net comprises a frame 1 and an anti-falling net 2 which is detachably installed in the frame 1, wherein a plurality of installation rods 3 are vertically installed at the bottom of the frame 1, the installation rods 3 are distributed at the bottom of the frame 1 along the outer contour of the frame 1, a sliding ring 21 is movably sleeved on each installation rod 3, and the sliding ring 21 is fixedly connected with the edge of the anti-falling net 2.
Wherein, be provided with multiunit tension module in the bottom of frame 1, every group tension module is two at least, and just about the 3 axisymmetric distributions of installation pole in the week side of installation pole 3, in this embodiment, tension module includes: the stretching device comprises a mounting tube 11 vertically fixed at the bottom of a frame 1, a stretching rod 12 slidably inserted in the mounting tube 11, a stretching spring 13 fixed at the top of the stretching rod 12, one end of the stretching spring 13 far away from the stretching rod 12 fixed on the top wall of the mounting tube 11, and one end of the stretching rod 12 far away from the mounting tube 11 fixed on a sliding ring 21 through an elastic pull rope (rubber rope).
When preventing weighing down net 2 and receiving the impact of the object that falls, prevent weighing down net 2 and can drive slip ring 21 and glide along installation pole 3, at this moment, extension spring 13 will utilize the restoring force of self, make slip ring 21 receive ascending pulling force, make slip ring 21 receive the power of buffer memory restriction, however, in practice, prevent weighing down the impact force that net 2 often received than great, tension module can not necessarily restrict the gliding of slip ring 21, therefore, in this implementation, still be provided with a plurality of buffer unit on installation pole 3, buffer unit distributes along the extending direction of installation pole 3.
The buffer unit includes: the cover is established and is established a plurality of sleeves 31 on installation pole 3, it is provided with buffer block 32 to encircle in the top outside of sleeve 31, buffer block 32 adopts the rubber material to make, good deformability has, it has a plurality of buffers 33 to articulate at buffer block 32's bottom edge, inboard at buffer block 33 is fixed with buffer spring 34, buffer spring 34 keeps away from buffer block 33's one end and fixes on sleeve 31's outer wall, when slip ring 21 overcomes extension spring 13's restoring force and continues the gliding, buffer block 32 receives the impact force and can deform, make slip ring 21 pass buffer block 32, but this moment, slip ring 21 can receive buffer restriction resistance of buffer block 32, thereby weaken the power that slip ring 21 slided.
It should be noted that, in this embodiment, the cross section of the buffer block 32 is a trapezoid with a narrow top and a wide bottom, and in a natural state, the buffer spring 34 drives the buffer sheet 33 to expand outward, at this time, the extending direction of the buffer sheet 33 is exactly the same as the extending direction of the trapezoid surface of the buffer block 32, and when the slip ring 21 passes through the buffer block 32 and continues to slide downward, the buffer spring 34 can also play a certain buffer limiting action force on the slip ring 21, so as to further increase the buffer resistance force on the slip ring 21 on the basis of the buffer block 32.
In addition, in the embodiment, the size of the buffer unit is gradually increased from the top to the bottom of the mounting rod 3, that is, the outer diameter of the buffer block 32 is gradually increased, it should be noted that the inner diameter of the sliding ring 21 is equal to the outer diameter of the buffer block 32 with the minimum size, but is smaller than the outer diameter of the buffer block 32 with the maximum size, so that the effect of buffering resistance to sliding of the sliding ring 21 is larger, and in cooperation with the stretching assembly, the mounting effect of the anti-falling net 2 can be effectively ensured, and the situation of separation between the anti-falling net 2 and the frame 1 can be avoided.
Still threaded connection has spacing ring 35 on installation pole 3, and spacing ring 35 mainly used restriction sleeve 31 prevents that sleeve 31 from gliding, when the height of every buffer unit is adjusted according to actual conditions to needs, also can be very convenient adjust buffer unit through rotatory spacing ring 35 to can enlarge the application scope of this application.
It should be further noted that the outer diameter of each limit ring 35 is the same as the outer diameter of the corresponding buffer block 32 of the buffer unit, and the cross section of the limit ring 35 is consistent with the cross section of the buffer block 32 and is trapezoidal, so that the advantage is that when the sliding ring 21 passes through the buffer unit, the limit ring 35 can further play a role in buffering and limiting the sliding ring 21, and meanwhile, when the sliding ring 21 slides upwards in the reverse direction, the reverse sliding resistance of the sliding ring 21 can be increased, so as to reduce the damage to the buffer unit.
In practice, when preventing that the impact force that falls net 2 and receive is great, slip ring 21 may break through all buffer unit, in order to prevent falling net 2 and protect on this basis, in this embodiment, still movable sleeve is equipped with limiting plate 4 in the bottom of installation pole 3, limiting plate 4's outline size is greater than slip ring 21's internal diameter, and still threaded connection has stop nut 41 in the bottom of installation pole 3, stop nut 41 both can be with limiting plate 4 restriction on installation pole 3, simultaneously, also can conveniently dismantle the change limiting plate 4.
In addition, the bearing surface of the limiting plate 4 is further provided with an annular groove 42, an annular block 43 is movably placed in the annular groove 42, a connecting spring 44 used for connecting the annular block 43 and the annular groove 42 is arranged between the annular block 43 and the annular groove 42, one end of the connecting spring 44 is connected to the bottom wall of the annular groove 42, and the other end of the connecting spring 44 is fixed to the bottom of the annular block 43.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
