Abstract
The utility model relates to a pulley support adopting a non-digging technology to lay a heat network pipeline, comprising semicircular upper and lower clamps fixedly connected with a pipeline, the pulley support is characterized in that, the external circles of the clamps are symmetrically provided with supporting legs, a rolling wheel is respectively in a pin joint with the top end of a supporting leg. The beneficial effects of the pulley support are in that: resistance between a pipeline and a push pipe can be reduced, and operating efficiency is improved; the pipeline is supported, guaranteeing pipeline position in the pipe.
Description
Technical field
The utility model belongs to the instrument that heat distribution pipeline is laid, and relates in particular to that a kind of laying is crossed the river, the pulley bracket of the heating pipeline in passageway.
Background technique
Heat supply network by defeated hot main line, join hot main line, branch line etc. and form.Defeated hot main line is drawn from thermal source, does not generally connect branch line; Join hot main line from failing hot main line or directly picking out, by joining a heat alignment user heat supply from thermal source.
The heat supply network layout is mainly determined according to city heat load distribution situation, block present situation, development plan and geology terrian condition etc., generally is arranged to dendritic.When by multi-source heating, for standby mutually, improve the reliability and the flexibility of heat supply, can establish connecting tube between the defeated hot main line of each thermal source, also can be arranged to ring-type.How along the street urban district pipeline road one side and other underground utility is arranged in parallel.The layout of heat supply network should make pipeline walk at the heat load center as far as possible, and heat range of heat is the shortest, and minimum to the city interference, construction and operation management are convenient.
Heat supply pipeline has underground laying and over ground installation dual mode.Underground laying does not influence the urban transportation and the appearance of the city, is the system of laying that city heat supply is extensively adopted.Over ground installation also claims built on stilts laying, and its low cost is easy to maintenance, is used for the special areas of geological structure such as industrial region, suburb, level of ground water height, permafrost area, settlement by soaking soil district more, and crosses over locations such as railway, highway, river.Majority is established special stand.According to the support height difference, be divided into high trestle, medium-height trestle, low trestle and ground and lay.Current, pay much attention to for exploitation river view economy in the city, so hot pipe network do not adopt the over ground installation method of crossing over the location, river, uses the laying method that passes through the river bed instead.This kind method is that the heat supply pipeline of 6 meters fixed length is pushed in the push pipe by joint, and every joint heating tube is fixedly connected by the clip head and the tail.In construction, advance the resistance of heating tube bigger, directly influence working efficiency.
The model utility content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and the pulley bracket that provides a kind of trenchless technology to lay the heating pipeline that crosses the river, and utilizes this support can reduce resistance between heating tube and the push pipe, and working efficiency is provided; Heating tube can also be supported, guarantee to keep certain distance between heating tube and the push pipe.The utility model for achieving the above object, by the following technical solutions: a kind of trenchless technology is laid the pulley bracket of the heating pipeline that crosses the river, comprise lower catch hoop on the semicircle of affixed heating tube, it is characterized in that: be arranged with rack leg on the described clip cylindrical, described rack leg top is connected with roller.
Each affixed pair of brackets leg on the described upward lower catch hoop both sides cylindrical.
Described rack leg and last lower catch hoop fixing position are provided with dihedral and strengthen gusset.
Beneficial effect: can reduce the resistance between heating tube and the push pipe, increase work efficiency; Heating tube is supported, can guarantee to keep certain distance between heating tube and the push pipe.Be symmetrical arranged rack leg on the cylindrical of last lower catch hoop both sides.In the heating tube forward engineer, can guarantee that heating tube all the time and keep certain distance between the push pipe.
Description of drawings
Fig. 1 is the utility model structural representation that places push pipe; Fig. 2 is the side view of Fig. 1.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of trenchless technology is laid the pulley bracket of the heating pipeline that crosses the river, and comprises lower catch hoop 2 on the semicircle of affixed heating tube, is arranged with rack leg 3 on the described clip cylindrical, and described rack leg top is connected with roller 4.Each affixed pair of brackets leg on the described upward lower catch hoop both sides cylindrical.Described rack leg and last lower catch hoop be affixed to be gone out to be provided with dihedral and strengthens gusset 5, stiffening rib board size 130 * 100mm.
During operation, the heat supply pipeline of 6 meters fixed length is pushed in the push pipe 1 by joint, every joint heating tube is fixedly connected by the clip head and the tail.Utilize the roller heating tube on the rack leg to push ahead easily, in the heating tube drive-in step, each affixed pair of brackets leg on the cylindrical of last lower catch hoop both sides is no matter how heating tube rotates, can guarantee that all heating tube all the time and keep certain distance, 50-100MM between the push pipe.The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (3)
1. pulley bracket that adopts trenchless technology to lay heat pipeline comprises lower catch hoop on the semicircle of affixed pipeline, and it is characterized in that: be arranged with rack leg on the described clip cylindrical, described rack leg top is connected with roller.
2. the pulley bracket of laying heat pipeline according to claim 1 is characterized in that: each affixed pair of brackets leg on the described upward lower catch hoop both sides cylindrical.
