Abstract
The utility model relates to a safety protection buffer device mainly used for solving the technical problems that an impact force borne when a buffer rope falls off can be neutralized by using a relatively large starting tearing force because a braided belt braided by using a belt braiding process for the buffer rope in the prior art is higher in the beginning and lower later once the braided belt is worn off, the process is more difficult to control if an elastic rubber rope is used and the like. The safety protection buffer device is composed of two layers of belt bodies (1) and is characterized in that the belt bodies (1) are high-strength terylene belts and are sewn together through a plurality of groups of sewing threads (2) which are arranged at intervals.
Description
Technical field
The utility model relates to a kind of buffer unit, especially relates to a kind of safeguard protection buffer unit.
Background technology
When work high above the ground, operating personnel are at the safeguard protection buffer unit of a kind of novelty of work high above the ground, in order to avoid when falling down, and the injury that the impulsive force producing due to own wt and acceleration causes operating personnel's health.Chinese patent discloses a kind of snub rope (Granted publication number: CN 202569242 U), it includes snub rope's body, be arranged on the auxiliary catch assembly at body two ends, snub rope, auxiliary catch assembly has included connector, be arranged on the snap fit on connector, snap fit is arcuation setting, snap fit one end is connected with connector, between the other end and connector, form opening, on connector, be positioned at opening inner side and be provided with groove, in groove, be provided with push pedal, locating dowel, spring, spring winding is in locating dowel, both ends of the spring respectively with push pedal, groove inwall is conflicted, described push pedal is set in locating dowel, on connector, be equipped with the cavity inserting for snub rope's body, after body two ends, snub rope insertion cavity, turn back and sew up fixing with the snub rope's body being positioned at outside cavity, the snub rope's body and the connector that are positioned at cavity are sewed up fixing, the snub rope's body that is positioned at cavity arranges in the form of a ring, push pedal lateral surface is provided with some sawtooth.But sort buffer rope is made into after belt by ribbon technique, because the tear edge of ribbon is originally higher, once tear, power is below less, therefore need larger starting tear edge (600kg) could offset impulsive force suffered while falling down, if use caoutchouc elasticity rope, the more difficult control of this technique (distance falling down, bounce situations etc.).
Utility model content
The utility model is to provide a kind of safeguard protection buffer unit; it is mainly to solve the existing snub rope of prior art to be made into after belt by ribbon technique; because the tear edge of ribbon is originally higher; once tear; power is below less; therefore need larger starting tear edge could offset impulsive force suffered while falling down, if use caoutchouc elasticity rope, the technical problem of the more difficult control of this technique etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of safeguard protection buffer unit of the present utility model, comprises belt body, and described belt body is high tenacity polyester fiber band, and belt body is two-layer, and sewn together by sewing thread between two-layer belt body, sewing thread is spaced many groups.The utility model can be in the long distance of 70cm, the pattern (tear edge is controlled at 400kg ± 50kg) of 95 same process of sewing, from this buffer unit, starting stressed first sewing pattern of tearing like this starts, till use up operating personnel's suffered impulsive force (about 2000kg) that falls down, the stressed 400kg ± 50kg that is stabilized on its health.Sewing technology is controlled by computer (full-automatic sewing machine): sewing velocity, sewing needle distance, sewing pattern (track).
As preferably, described two-layer belt body is that same body bending forms, and the bending two ends of belt body circularizes body, and annular solid end is made fixing by sewing thread.Make so comparatively simple.
As preferably, the length L of described two-layer belt body is 650-750mm, and on it, spaced sewing thread is 95 groups.
Therefore, the utility model is to (sewing thread intensity after high-strength polyester band (rupture strength < 2500kg) accurate Calculation sewing intensity, sewing needle distance, sewing pattern etc.), by the mode of sewing technology, make and form, when being subject to impulsive force, sewing thread is torn in order when being subject to certain power (400kg ± 50kg), with payment suffered impulsive force (about 2000kg) while falling down, make the suffered power of operating personnel's health, be stabilized in certain scope (Europe superscript is < 600kg), in order to avoid user is injured, simple in structure, rationally.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is plan structure schematic diagrames of Fig. 1.
Parts, position and numbering in figure: belt body 1, sewing thread 2, annular solid 3.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of safeguard protection buffer unit of this example; as shown in Figure 1, Figure 2; comprise belt body 1, belt body is high tenacity polyester fiber band, and belt body is two-layer; sewn together by sewing thread 2 between two-layer belt body; sewing thread is spaced 95 groups, and the total length L of two-layer belt body is 700mm, and two-layer belt body is that same body bending forms; and the bending two ends of belt body circularizes body 3, annular solid end is made fixing by sewing thread.
When being subject to impulsive force, sewing thread 2 is torn in order when being subject to certain power, and suffered impulsive force while falling down to offset, makes the suffered power of operating personnel's health, is stabilized in certain scope, in order to avoid operating personnel is injured.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
Claims (3)
