Description

The assembled type cable testing bridge

Technical field

The utility model relates to a kind of cable testing bridge, refers to a kind of assembled type cable testing bridge of plastics especially.

Background technique

Cable testing bridge is electric wire, cable, pipe cable to be laid reach standardization, seriation, unitized cable laying device.Present employed cable testing bridge, its material is generally metallic material such as stainless steel, glass fibre reinforced plastics and aluminum alloy, and cost is higher, and must handle through surface anticorrosion before use, and technology is complicated.Even so, when being applied to the stronger occasion of some corrosivity, crane span structure still can corrosion, need repair or replace new crane span structure, because the metal crane span structure is relatively heavier, and the difficulty that can increase maintenance or change greatly.

For overcoming the deficiency of metallic cable crane span structure, Plastic cable bridge arises at the historic moment, but the narrow limitation with size that existing Plastic cable bridge has, its width and length are unadjustable, the mould that need make different size is produced the crane span structure of different size, can strengthen the cost expenditure.The crane span structure that part can be regulated size is spliced, can satisfy the requirement of different size by the splicing of polylith group plate, but has the splicing insufficient strength, or defective such as splicing construction more complicated.

The model utility content

The assembled type cable testing bridge that technical problem to be solved in the utility model provides a kind of dimension adjustable, winding intensity height, is easy to process.

For solving the problems of the technologies described above, the technical solution of the utility model is to provide a kind of assembled type cable testing bridge, comprises symmetrical two side plates and at least one base plate, and the two ends of described base plate are connected with group by a plate and described side plate respectively; Described connecting plate comprises two joints, and wherein a junction and side plate join, and an end of another joint and described base plate is connected with group; The connecting end that described side plate and described connecting plate join is formed with groove, and a junction of described connecting plate inserts in the described groove; Described base plate middle part has cavity, in establish many stiffening ribs, described base plate middle part will be divided into a plurality of chambers, corresponding therewith, the joint of described connecting plate is a plurality of lug bosses spaced apart, corresponding each chamber that insert of described a plurality of lug bosses;

The groove inwall of described side plate is formed with sawtooth, corresponding with it, the joint upper and lower end face of described connecting plate is formed with sawtooth; Described side plate and base plate are the plastic board that the middle part has cavity, are provided with stiffening rib in its cavity; The periphery of two joint connections of described connecting plate is formed with a ring wall.

The utility model can reach following beneficial effect by technique scheme:

1, the size of crane span structure can be regulated as required, be easy to processing: the width of described side plate and base plate is fixed, length can intercept as required, base plate is to be connected with group with biside plate in the longitudinal direction, therefore the base plate of the suitable length of intercepting can satisfy the needs of crane span structure width, the length of crane span structure is by the length decision of biside plate, therefore the side plate of the suitable length of intercepting can satisfy the needs of crane span structure length, only need winding base plate spaced apart between biside plate, whole crane span structure simple in structure is easy to processing.

2, side plate and base plate winding are firm, cooperate the intensity height: described biside plate is in the same place by the connecting plate winding with base plate, side plate and connecting plate are that the engagement by the sawtooth of the sawtooth of groove inwall and joint upper and lower end face is connected with group, base plate and connecting plate are that the fit by each chamber and each lug boss of joint is connected with group, so connecting structure has very high cooperation intensity, can guarantee that side plate and base plate winding are firm.

3, the structural strength height of crane span structure: the middle part of described side plate and base plate all has cavity, is distributed with stiffening rib therebetween, and so structure is not only saved material, and has higher structural strength than entity sheet material, therefore can strengthen the structural strength of whole crane span structure.

Embodiment

See also Fig. 1, shown in Figure 2, the utility model assembled type cable testing bridge by the side plate 10 of two symmetries, place two base plates 20 between the biside plate 10 and two links 30 to be connected with group to form.

This side plate 10 is L shaped plastic board, and the open end of its bottom is a connecting end 11, is formed with a groove 12 therebetween, and this groove 12 is a serrated slot, and its wall is formed with sawtooth 120, and the middle part of this side plate 10 is formed with cavity, is distributed with many stiffening ribs 13 therebetween;

This base plate 20 is the rectangular plastic plate, and it is closed end along its length, and broad ways forms two open ends, this open end is a connecting end 21, the middle part of this base plate 20 is formed with cavity, is distributed with the many stiffening ribs 22 that extend along its length therebetween, and cavity is divided into a plurality of chambers 23;

This connecting plate 30 comprises two
