Abstract
The utility model relates to a seamless specially-shaped pipe for scaling ladders of fire trucks. The seamless specially-shaped pipe is characterized by comprising a pipe body, wherein the pipe body comprises a first transverse section, the left end of the first transverse section is connected with a first vertical section arranged vertically, the top of the first vertical section is connected with a first inclined edge inclined to the upper right side, the right end of the first inclined edge is connected with a second transverse section, the right end of the second transverse section is connected with a second inclined edge inclined to the lower right side, the right end of the second inclined edge is connected with a second vertical section arranged vertically, the bottom of the second vertical section is connected with a third inclined edge inclined to the lower left side, the bottom of the third inclined edge is connected with the right end of the first transverse section, all pipe walls of the pipe body are in arc transition, and the surface of the pipe body is coated with an anticorrosion coating. Compared with previous square pipes, the seamless specially-shaped pipe for the scaling ladders of the fire trucks is higher in strength, has certain bending resistance, torsion resistance and vibration resistance and is higher in anticorrosion performance, and materials and costs are saved.
Description
Technical field
The utility model relates to a kind of shape tube, for aerial ladder of fire truck, is a kind of seamless heterotype pipe.
Background technology
At present, seamless steel pipe is widely used in manufacturing structure part and machine components, as steel scaffold of using in oil drill rocker, truck drive shaft and building operations etc.Manufacture ring-shaped work pieces with seamless steel pipe, can improve stock utilization, simplify manufacturing process, save material and save man-hour.In these seamless steel pipes, square tube is in the time bearing inside or outer radial pressure, stressed more even, and therefore most seamless steel pipes are square tubes.
But square tube is because shape limits, and makes it cannot be used for some particular surroundings, because the moment of inertia of square tube and modulus of section are less, intensity is low, its bending resistance, antitorque and shock resistance is poor, and it is more to make the steel that square tube consumes, and makes its cost higher.Above a variety of causes has limited the scope of application of square tube, therefore under some particular surroundings, does not adopt square tube to be used as structural member or machine part.
The seamless pipe of for example using on aerial ladder of fire truck, need to this seamless pipe there is higher intensity and certain bending resistance, antitorque, shock resistance, common like this square tube just can not reach requirement.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of intensity higher, has certain bending resistance, antitorque, shock resistance, and saves material, the cost-saving seamless heterotype pipe for aerial ladder of fire truck.
The purpose of this utility model is achieved in that
The utility model is for the seamless heterotype pipe of aerial ladder of fire truck, it comprises body, body comprises the first crosspiece, the left end of described the first crosspiece is connected with the vertically disposed first perpendicular section, the top of the described first perpendicular section is connected with the first hypotenuse to the oblique setting in upper right side, the right-hand member of described the first hypotenuse is connected with the second crosspiece, the right-hand member of the second crosspiece is connected with the second hypotenuse to the oblique setting in lower right, the right-hand member of the second hypotenuse is connected with the vertically disposed second perpendicular section, the bottom of the second perpendicular section is connected with the 3rd hypotenuse of the oblique setting in below left, the bottom of described the 3rd hypotenuse is connected with the right-hand member of the first crosspiece, between each tube wall of described body, be arc transition, the surface of described body scribbles corrosion-inhibiting coating.
The utility model has the following advantages for the seamless heterotype pipe of aerial ladder of fire truck:
The utility model is for the seamless heterotype pipe of aerial ladder of fire truck, and compared with square tube in the past, its intensity is higher, has certain bending resistance, antitorque, shock resistance, and saves material, cost-saving, also has higher antiseptic property simultaneously.
Accompanying drawing explanation
Fig. 1 is the body sectional view of the utility model for the seamless heterotype pipe of aerial ladder of fire truck.
Fig. 2 is the layer structure schematic diagram of the utility model for the seamless heterotype pipe of aerial ladder of fire truck.
In figure: body 1, the first crosspiece 2, the first perpendicular section 3, the first hypotenuse 4, the second crosspiece 5, the second hypotenuse 6, the second perpendicular section 7, the 3rd hypotenuse 8, corrosion-inhibiting coating 9.
The specific embodiment
Referring to Fig. 1, the utility model relates to a kind of seamless heterotype pipe for aerial ladder of fire truck, this it comprise body 1, body 1 comprises the first crosspiece 2, the left end of described the first crosspiece 2 is connected with the vertically disposed first perpendicular section 3, the top of the described first perpendicular section 3 is connected with the first hypotenuse 4 to the oblique setting in upper right side, the right-hand member of described the first hypotenuse 4 is connected with the second crosspiece 5, the right-hand member of the second crosspiece 5 is connected with the second hypotenuse 6 to the oblique setting in lower right, the right-hand member of the second hypotenuse 6 is connected with the vertically disposed second perpendicular section 7, the bottom of the second perpendicular section 7 is connected with the 3rd hypotenuse 8 of the oblique setting in below left, the bottom of described the 3rd hypotenuse 8 is connected with the right-hand member of the first crosspiece 2, between each tube wall of described body 1, be arc transition.
As Fig. 2, the surface of described body 1 scribbles corrosion-inhibiting coating 9, and this corrosion-inhibiting coating 9 is epoxy resin.
This seamless heterotype pipe for aerial ladder of fire truck is compared with square tube in the past, and its intensity is higher, has certain bending resistance, antitorque, shock resistance, and saves material, cost-saving, also has higher antiseptic property simultaneously.
