Abstract
The utility model discloses an inhaul cable protective sleeve and belongs to the technical field of building engineering. The inhaul cable protective sleeve is provided with two half-tube bodies, wherein the connection portions of each half-tube body are provided with a draw pin and a mortise respectively. A protruding spiral rib is arranged on the outer side face of each half-tube body. Under the condition that a circular tube is formed by the two half-tube bodies when the draw pin of one half-tube body is inserted into the mortise of the other half-tube body, the spiral ribs outside the two half-tube bodies are mutually connected in a butt joint mode. According to the inhaul cable protective sleeve, the problem of wind and rain shock excitation of a common high density polyethylene protective sleeve can be solved.
Description
Technical field
The utility model relates to construction engineering technical field, especially a kind of protective jacket of building guy cable.
Background technology
Building guy cable is the critical component that is applied on construction work, especially the bridge structure, drag-line inside is steel wire, finalize the design by the band colligation, pack into the high density polyethylene (HDPE) sheath again, protective sleeve of pulling cable plays the antisepsis of hawser, the cross section profile of drag-line is circular, and the pe sheath surface is comparatively smooth.This ganoid pe sheath descends at the service condition with wind and rain, causes rain wind induced vibration easily, i.e. significantly vibration, and in order to solve this rain wind induced vibration, it is in the pe sheath surface soldered spiral convex rib to be arranged that a kind of technical scheme is arranged.But, this external surface have spiral convex rib protective sleeve of pulling cable install and use very inconvenient, generally speaking, for the convenience of producing and transporting, this protective sleeve of pulling cable is made the specification of 6-8 rice length mostly, and a lot of bridge cables often reach km, even it is longer, so Chang bridge cable need be sleeved on ground of a large amount of protective sleeve of pulling cable on the long bridge cable when above-mentioned protective sleeve of pulling cable is installed, also need each root protective sleeve of pulling cable is welded together in the junction, engineering quantity is quite big, and operation is difficulty quite, under many circumstances even can't construct.In order to solve of the inconvenience of many protective sleeve of pulling cable by root suit and welding, people's utility model a kind of protective sleeve of pulling cable, this protective sleeve of pulling cable surrounds a tubular shape by the mutual fastening of two-part semicanal by the junction surface.One in two junction surfaces of this semicanal is draw pin, and another is a tongue-and-groove.But the protective sleeve of pulling cable lateral surface that this semicanal fastens remains smooth, does not have the effect that prevents rain wind induced vibration.
The utility model content
Technical problem to be solved in the utility model provides the protective sleeve of pulling cable of the anti-exciting of a kind of efficient corrosion resisting, and this protective sleeve of pulling cable can solve the problem of general high density polyethylene (HDPE) sheath rain wind induced vibration.
In order to address the above problem, the technical solution adopted in the utility model is: this protective sleeve of pulling cable, have the semicanal body that is provided with draw pin and tongue-and-groove at two junction surfaces respectively, and be provided with the spiral rib of projection at the lateral surface of described semicanal body.
In the above-mentioned protective sleeve of pulling cable technical scheme, technical scheme can also be more specifically: the draw pin of described two semicanal bodies by their sides inserts in the opposing party's the tongue-and-groove and constitutes under the state of pipe, and the external spiral rib of these two semicanals docks mutually.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, the helix of the protrusion of protective sleeve of pulling cable external surface can stop the formation of rain line, has the effect of weather proof exciting.
2, the installation of sheath is simple and convenient, and jacket inner wall can not be subjected to the damage of drag-line steel wire.
Description of drawings
Fig. 1 is the structural representation of protective sleeve of pulling cable.
Fig. 2 is Fig. 1 vertical view.
Fig. 3 is the structural representation of semicanal body.
Fig. 4 is the vertical view of Fig. 3.
Fig. 5 is the I place enlarged drawing of Fig. 2.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Include the semicanal body that is provided with draw pin 2 and tongue-and-groove 3 at two junction surfaces respectively as Fig. 1 to protective sleeve of pulling cable shown in Figure 5, be provided with the spiral rib 1 of projection at the lateral surface of semicanal body.During installation, with two semicanal bodies with between drag-line parcel and they, their sides' draw pin 2 is inserted in the opposing party's the tongue-and-groove 3 and constitute pipes, drag-line is surrounded in this pipe, constitute under the state of pipe, the external spiral rib 1 of these two semicanals docks mutually and forms continuous helix, all loads onto the semicanal body until the part that need protect at drag-line.This protective sleeve of pulling cable, stop the formation of rain line, prevent the rain wind induced vibration of drag-line effectively and install simple and conveniently, can after drag-line installs, carry out sheath and install, do not hinder the inwall of protective sleeve of pulling cable, change circular pipe type sheath in the past and must before the drag-line two ends are fixing, be installed to unfavorable situation on the drag-line.The utility model both can be used for the installation construction of new bridge, can be used for the maintenance and the replacing of old bridge protective sleeve of pulling cable again.Effect with weather proof exciting has greatly improved the antiseptic property of drag-line.
Claims (2)
1. a protective sleeve of pulling cable has the semicanal body that is provided with draw pin (2) and tongue-and-groove (3) at two junction surfaces respectively, it is characterized in that: the spiral rib (1) that is provided with projection at the lateral surface of described semicanal body.
2. protective sleeve of pulling cable according to claim 1, it is characterized in that: the draw pin (2) of described two semicanal bodies by their sides inserts in the opposing party's the tongue-and-groove (3) and constitutes under the state of pipe spiral rib (1) butt joint mutually that these two semicanals are external.
