Embodiment
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is described in more detail.Should be appreciated that embodiment described herein only in order to explain the present invention, but be not intended to limit the present invention.
As shown in Figure 1, Figure 3, according to the protection assembly for casing of the embodiment of the present invention, comprising: the first cushion block 10, second cushion block 20 and the bundling strap 30 for locking.
Specifically, the lower end of the first cushion block 10 and the upper end of the second cushion block 20 are closely adjacent to and are configured with the receiving bore in axial direction extended being suitable for assembling sub-pipe 4 between the first cushion blocks 10 and the second cushion block 20, second cushion block 2 lower end has and is suitable for the first groove 21 that clamp with female pipe 50, that in axial direction extend, bundling strap 30 is connected with the first cushion block 10, second cushion block 20, female pipe 50 respectively, is fixed by sub-pipe 40 with female pipe 50.
According to an embodiment of the invention for the protection assembly of casing; limit the relative movement between sub-pipe 40 and female pipe 50; and bundling strap 30 ensure that the transmission of power between sub-pipe 40 and female pipe 50; disperse single stressed; alleviate the impact of external load antithetical phrase pipe 40, make the even reasonable layout of external load.
As shown in Figure 1 and Figure 4; according to an embodiment of the invention for the protection assembly of casing; the lower end of the first cushion block 10 is provided with and in axial direction extends the second groove 11; the upper end of the second cushion block 20 is provided with symmetrically arranged 3rd groove 22 with the second groove 11; second groove 11 and described 3rd groove 22 are configured for the receiving bore holding sub-pipe 40; thus, sub-pipe 40 is made to obtain supportive protection.
As shown in Figure 4; according to an embodiment of the invention for the protection assembly of casing; the cross section of the upper end of the first cushion block 10 is circular arc; the cross section of the first groove 21 and the second groove 11 is semicircle; the cross section of the 3rd groove 22 is circular arc, makes the first cushion block 10, second cushion block 20 antithetical phrase pipe 40, female pipe 50 plays protective action better.
According to an embodiment of the invention for the protection assembly of casing, the first cushion block 10 and the second cushion block 20 are rubber parts, when making group pipe 40 and female pipe 50 be subject to external load function, play the effect of buffer protection.
As shown in Figure 4; according to an embodiment of the invention for the protection assembly of casing; second cushion block 20 upper end radial dimension is less than lower end radial dimension; from longitudinal section view; the shape of the second cushion block is similar to the shape of a saddle; this profile design is conducive to reducing raw material needed for preparation second cushion block, saves manufacture cost simultaneously.Bundling strap 30 adopts metal tape, due to the high strength of metal tape, more firm when being fixed bondage to the first cushion block 10, second cushion block 20 and female pipe 50, and not easily damaged, thus, ensure that do not have relative sliding between sub-pipe 40 and female pipe 50.
During use, first the first groove 21 clamping of the second cushion block 20 is installed on female pipe 50, after clamping, sub-pipe 40 is positioned in the 3rd groove 22 of the second cushion block 20, the first cushion block 10 is placed afterwards on sub-pipe 40, then sub-pipe 40 is contained in the receiving bore of the second groove 11 of the first cushion block 10 and the 3rd groove 22 formation of the second cushion block 20 completely, finally utilizes bundling strap 30 to be fixed by female pipe 5, first cushion block 1, second cushion block.
Adopt above-mentioned cushion block mounting fixture be fixed on female pipe 50 by sub-pipe 40 and there is no relative torsion and slip, prevent the sub-pipe of installation period 40 to be positioned at below female pipe 50, be conducive to protecting sub-pipe 40.
Bundling strap 30 is always in tensioning state, ensures the transmission of power between sub-pipe 40 and female pipe 50, and the power suffered by bundling strap 30 comprises the vertical force that sub-pipe 4 is shifted to or produced away from female pipe 50; The internal force that sub-pipe 40 and the horizontal relative torsion of female pipe 50 produce and the horizontal tangential power that hydrodynamic force produces; The axial force that deadweight and the internal force between sub-pipe 4 and jig produce.Rational tension force can realize the power transmission between thin bar part and thick bar part, disperses single stressed, realizes the even reasonable layout of load.
Meanwhile, be positioned at the first cushion block 10 above sub-pipe 40, concrete blocks can be avoided to directly act on above sub-pipe 40, play a protective role, in addition, be positioned at the second cushion block 20 below sub-pipe 40, play buffer function, sub-pipe 40 can be protected to be subject to the destruction of external environment.
Description of the invention provides in order to example with for the purpose of describing, and is not exhaustively or limit the invention to disclosed form.Wherein many modifications and variations are obvious for the ordinary skill in the art.Selecting and describing embodiment is in order to principle of the present invention and practical application are described better, and enables those of ordinary skill in the art understand the present invention thus design the various embodiments with various amendment being suitable for special-purpose.
