Abstract
The utility model relates to an energy-absorbing four segmentation clamping pieces that shocks resistance, its surface are the cone, include: the two clamping pieces are oppositely arranged, and an elastic groove is formed in the middle of each clamping piece. The utility model discloses can more effectively transmit the absorption work of impact, improve the shock resistance of ground tackle under the impact load, keep the anchor power of anchor rope and be convenient for the installation.
Description
Technical Field
The utility model belongs to the technical field of the colliery is strutted, a four segmentation clamping pieces are shocked resistance to the energy-absorbing is related to, especially a four segmentation clamping pieces are shocked resistance to mining energy-absorbing with shock load, adaptation high earth pressure large deformation that shocks resistance.
Background
The coal mining roadway needs to be supported by an anchor rope, the common anchor rope consists of a steel strand, an anchor assembly part and a tray, during construction, a hole is drilled in a coal seam (or rock stratum), a resin anchoring agent is fed into a drilled hole channel, then the steel strand is stirred to be bonded with the resin anchoring agent, the lower end of the steel strand is sleeved on the steel strand by a tray supporting anchor, the steel strand is tightly attached to the coal seam, and finally the steel strand is tensioned and anchored by a clamping piece anchor, so that the supporting function of the anchor rope is completed.
The traditional three-part clip is formed by splicing three separated clips and anchors steel wires by means of clamping acting force between steel strands and the clips. When high ground pressure (mine pressure) arrives suddenly, use this kind of clamping piece, because trisection formula clamping piece and steel strand wires can not closely laminate, lead to steel strand wires and ground tackle slippage easily to lead to the anchor inefficacy, ground tackle fracture, bite off steel strand wires, ground tackle fly and collapse, cause the anchoring force of anchor rope to lose, cause very big potential safety hazard for the coal mine.
Therefore, how to develop a clip that is easy to install and can be tightly attached to the steel strand is a technical problem to be solved by those skilled in the art.
Through searching, the document of the prior art which is the same or similar to the utility model is not found.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome not enough among the prior art, provide a simple structure, be convenient for the installation and can closely laminate with the steel strand wires four segmentation clamping pieces.
The utility model provides a its realistic problem take following technical scheme to realize:
an energy-absorbing impact-resistant four-split clip, the outer surface of which is conical, comprising: the two clamping pieces are oppositely arranged, and an elastic groove is formed in the middle of each clamping piece.
And the width of the groove of the elastic groove is 0.5-1 mm.
Moreover, the inner surface of the clamping piece is in a tooth shape.
The utility model has the advantages and beneficial effect:
1. the utility model provides an energy-absorbing impact-resistant clamping piece sets up the elasticity groove respectively through in the middle of the clamping piece of two relative settings, increases the inseparable laminating nature of clamping piece and steel strand wires, and then more effective transmission absorbs the percussion power, improves the shock resistance of ground tackle under the impact load, keeps the anchor power of anchor rope.
2. The utility model discloses a two formula clamping pieces, the installation of being convenient for.
3. The utility model discloses a fluting width of elasticity groove is 0.5 ~ 1mm, and through verifying many times, this fluting width can make the inseparable laminating nature best of clamping piece and steel strand wires.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
description of the reference numerals:
1-a clip; 2-elastic groove.
Detailed Description
The embodiments of the present invention will be described in detail below with reference to the accompanying drawings:
an energy-absorbing impact-resistant four-split clip, as shown in fig. 1, having a conical outer surface, comprising: the two oppositely arranged clamping pieces are provided with an elastic groove in the middle, and the width of the groove is 0.5-1 mm.
In this embodiment, the inner surface of the clip is toothed.
The utility model discloses a theory of operation is:
the outer surface of the four-segment impact clamping piece is made into a cone, then the cone is cut into two pieces, an elastic groove is cut in the middle of each piece to form a four-segment impact clamping piece, and the four-segment impact clamping piece is convenient to sleeve on a steel strand to clamp the steel strand; and can be tightly attached to the steel strand, and the inner hole of the clamping piece is made into a tooth shape to be occluded with the steel strand.
When high ground pressure (mine pressure) suddenly comes, the coal bed suddenly moves downwards, and impact energy acts on the clamping piece, the clamping piece is designed into a four-split shape, and is more tightly attached with a steel strand compared with a common three-piece type clamping piece, so that the clamping piece has an impact resistance function; impact load is more effectively transferred to the steel strand;
the energy-absorbing impact-resistant clamping piece transfers impact load to the steel strand, and the steel strand produces a certain amount of elongation to absorb a part of impact energy.
It should be emphasized that the embodiments described herein are illustrative and not restrictive, and thus the present invention includes, but is not limited to, those embodiments described in this detailed description, as well as other embodiments derived from the technical solutions of the present invention by those skilled in the art, and all such embodiments are also within the scope of the present invention.
Claims (2)
