Abstract
The utility model discloses a kind of lifting crane span structure Special line laying tool, comprise " people " word ladder, described " people " word ladder has two; Described " people " word ladder is made up of pulley, the first supporting leg, the second supporting leg, fastening line; It is characterized in that, described first supporting leg is connected with the second supporting leg; Described pulley is arranged on the top of the first supporting leg and the second supporting leg; Described fastening linear system is in the bottom of the first supporting leg and the second supporting leg.The utility model, by practice, reaches reasonable in design, safe and convenient to use, improves operating efficiency.
Description
Technical field
The utility model relates to a kind of paying-off implement, specifically a kind of lifting crane span structure Special line laying tool.
Background technology
Along with socio-economic development, people are more and more higher to housing need, little high-rise residential building enjoys common people to like, the power cable distribution of little high level mostly is crane span structure and lays, cable testing bridge has lightweight, cost is low, handsome in appearance, structure is simple, the feature such as easy for installation, but in cable laying construction, because cable testing bridge space is less, unwrapping wire lower sheave cannot be used, cable is larger at the discrepancy point pulling force of crane span structure, the mechanical strength of crane span structure cannot meet, the crane span structure Special line laying tool energy carrying cable of the application is at the discrepancy point of crane span structure, the pulling force of cable when unfolding is made to drop on support, thus constructability, crane span structure is avoided to be subject to tensile failure.
Utility model content
The purpose of this utility model is to provide a kind of lifting crane span structure Special line laying tool, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of lifting crane span structure Special line laying tool, comprise " people " word ladder, described " people " word ladder has two; Described " people " word ladder is made up of pulley, the first supporting leg, the second supporting leg, fastening line; Described first supporting leg is connected with the second supporting leg; Described pulley is arranged on the top of the first supporting leg and the second supporting leg; Described fastening linear system is in the bottom of the first supporting leg and the second supporting leg.
As fluted in the middle of preferably described pulley.
Be stainless steel as the first preferably described supporting leg and the second supporting leg.
Anchor line (string) hole is left as the first preferably described supporting leg and the second supporting leg bottom.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is a kind of lifts the discrepancy point of crane span structure Special line laying tool energy carrying cable at crane span structure, the pulling force of cable when unfolding is dropped on support, thus constructability, avoid crane span structure to be subject to tensile failure, by practice, reach reasonable in design, safe and convenient to use, improve operating efficiency.
Accompanying drawing explanation
Overall structure schematic diagram when Fig. 1 is use of the present utility model.
Wherein: 1, pulley, the 2, first supporting leg, the 3, second supporting leg, 4, fastening line;
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of lifting crane span structure Special line laying tool, comprise " people " word ladder, described " people " word ladder has two; Described " people " word ladder is made up of pulley 1, first supporting leg 2, second supporting leg 3, fastening line 4; Described first supporting leg 2 is connected with the second supporting leg 3; Described pulley 1 is arranged on the top of the first supporting leg 2 and the second supporting leg 3; Described fastening line 4 ties up to the bottom of the first supporting leg 2 and the second supporting leg 3.
As fluted in the middle of preferably described pulley 1.
Be stainless steel as the first preferably described supporting leg 2 and the second supporting leg 3.
Anchor line (string) hole is left as the first preferably described supporting leg 2 and the second supporting leg 3 bottom.
The utility model one lifting crane span structure Special line laying tool, comprise " people " word ladder, described " people " word ladder has two, its structure is identical, the first described supporting leg is connected with the second supporting leg, forms " people " font, is convenient to regulate its height, and be stainless steel, make the terraced pulling force that can meet when bearing unwrapping wire of " people " word, be equipped with pulley in double ladder upper end, thus reduce cable friction power, the fastening line in double ladder bottom is fixed, and prevents double ladder from breakking away.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection range that all should be included in technical solutions of the utility model.
