The utility model relates to a steel tube holding pole for vertically installing a high voltage line iron tower group, which comprises a holding pole main body, a holding pole head and a holding pole bottom; the holding pole is divided into a plurality of pole bodies, and two ends of the holding pole are respectively the holding pole head and a holding pole tail; the holding pole main body, the holding pole head and the holding pole bottom are of a box type structure; the holding pole head and the holding pole main body, the holding pole bottom and the holding pole main body, and a main pole and a plurality of the pole bodies are respectively connected; and a coupling flange is arranged into a square by an angle iron, the vertical edges of the angle iron are welded with the main pole on the kerfs of four corners, and the flanges are mutually connected on the horizontal edges and are fastened by a bolt. The lifting point arranged on the holding pole head is of the structure of double lifting points so that the lifting points can conveniently be alternated, and is connected with a rotatable device. A lifting lug is integrally welded at a lifting lug position by a cross support so that a force is integrally applied on the lifting lug. The supports and the lifting lugs arranged on the bottom corners use the structure that the supports and the lifting lugs are firstly crossed and then inserted into a chord member, thus having a little influence on the chord member under the complicated outside force.
Description
Technical field
The utility model relates to a kind of upright installed steel pipe pole of high-tension line iron tower group that is used for.
Background technology
The upright most pole that uses of facility pole of installing of the existing widely used power grid construction high tension overhead power line iron tower group of China mainly contains two big classes: angle steel class and angle aluminium class, the subject matter that angle steel class pole exists is from great, the upright on-the-spot a dead lift of iron tower group is difficulty quite, and the fast limit of pole is serious to bearer's shoulder, neck compressing; The subject matter that angle aluminium class pole exists is " three height ": aluminium extruded sections price height, and it is high to make requirement, and on-site maintenance requires high, and angle aluminium pole suffers that collision just is easy to generate distortion, and very difficult the correction causes pole to be scrapped in advance.And the suspension centre of pole adopts single suspension centre, and the conversion of suspension centre is very difficult.External force also usually can make hanger problems such as unbalance stress is insecure occur to the influence of hanger during use.
Summary of the invention
The purpose of this utility model provide a kind of satisfy the upright a kind of light weight of being badly in need of of extra high voltage line iron tower group, cost low, reliably facility are installed.
Pole of the present utility model comprises pole main body, pole head and pole bottom; Pole is divided into the plurality of sections body of rod, and the pole two ends are respectively pole head and pole afterbody; Pole main body, pole head and pole bottom are box structure; Between pole head and pole main body, pole bottom and the pole main body and the mobile jib plurality of sections body of rod with being connected; Adpting flange is combined into square with angle steel, repaiies otch by angle steel stile and mobile jib welding for four jiaos, and it is to form by bolton in horizontal sides that flange interconnects, and the hanger of pole head is that two suspension centre structures are connected with rotational structure; The backguy hanger adopts cross to be welded into one; Bottom corner support hanger adopts right-angled intersection to inject the structure of chord member again.
The beneficial effects of the utility model are:
The utility model is set to two suspension centre structures by the suspension centre at the pole head, conversion suspension centre easily, and be connected with rotating device.Adopt cross that hanger is welded into one at the hanger place, hanger just can be whole stressed like this.Bottom corner support hanger has adopted right-angled intersection to inject the structure of chord member again, and the influence to chord member under complicated outside force of support hanger is very little.Make it have light weight, low, the reliable advantage of cost, satisfy the demand of extra high voltage line iron tower group.
Description of drawings
Fig. 1 is the structural representation of the utility model steel pipe pole.
Fig. 2 is the enlarged drawing of pole head 1.
Fig. 3 is the enlarged drawing of pole afterbody 6.
The specific embodiment
As shown in Figure 1, pole 2 is made of pole main body 3, pole head 4 and pole bottom 5, and pole is divided into the plurality of sections body of rod, and the pole two ends are respectively pole head 4 and pole afterbody 5.
Fig. 2 is 1 a partial enlarged drawing in Fig. 1 pole head 4, and hanger 8 is designed to two suspension centre turntables 7.
Fig. 3 is the enlarged drawing at 6 positions in the pole afterbody 5, and at backguy hanger 10 places, backguy hanger 10 passes chord member 9, adopts cross that backguy hanger 10 is welded into one again.At bottom corner support hanger 11, adopt right-angled intersection to inject the structure of chord member 9 again.
Specific embodiment: pole 2 pattern lengths: 42m, pole main body 3 long 36m, cross section 900 * 900mm, two end sections, 340 * 340mm (tube hub is the summit).Main material is selected Q345 φ 76 * 4 tubing for use, and flange is selected Q345 ∠ 75 * 6 angle steel for use.Web member selects Q235 φ 32 * 2.5 tubing.Require pole maximum allowable static load loading 70kN.
For convenient transportation and scene having bad luck, and consider easy to makely, the long structure of 42m is divided into 11 joints, uniform section part 9 joints, and every joint 4m, variable cross-section respectively 1 save end to end, and every joint length is 3m; Consider the interchangeability of standard knot assembling and alleviate deadweight that web member is arranged and is divided into 4 retainings; For making things convenient for pole conversion suspension centre 8, hanger 8 is designed to two suspension centre turntables.Pole internode adpting flange is combined into square with angle steel, repaiies otch by angle steel stile and mobile jib welding for four jiaos, and it is to form by bolton in horizontal sides that flange interconnects.Compare common latch and connect, angle steel flange connects to have to be made easily, and interchangeability is good, also is convenient to on-the-spot pole combination.Because of pole head 4 directly bears moment of flexure, so head 4 load partial design are become box structure.At backguy hanger 10 places, for alleviating the effect of backguy load to chord member 9, backguy hanger 10 passes chord member 9, adopts 2 φ, 76 * 4 seamless pipe crosses that 4 backguy hangers 10 are welded into one again, and 4 backguy hangers 10 are whole stressed, are more rational load-carrying construction.The 4 diagonal angle support hangers 11 in the bottom adopt right-angled intersection to inject the structure of chord member 9 again, and support hanger 11 is subjected to complicated outside force again, and is all quite limited to the adverse effect of chord member 9.
Have major defect at two class pole structure designs in the past, mobile jib of the present utility model and web member all adopt seamless steel pipe, and the pole of steel tubular structure has from heavy and light with respect to the pole of angle steel structure, and wind load is little, and supporting capacity is big.Onsite moving also will make things convenient for manyly.As a comparison, the utility model length overall 42m, specified lift heavy 7t, deadweight 2.573t; And 800 angle steel pole length overall 36m of our company's contemporary designs, specified lift heavy 7t, deadweight 2.583t, though specified lift heavy and conduct oneself with dignity identical, the effective height of angle steel pole is low 6m.With respect to angle aluminium pole, cost of the present utility model is low, and is easy to make, also quite firm.
