Abstract
The invention belongs to the technical field of rail transit equipment, and particularly relates to integral shed cloth for a through passage, which is an integral annular structure formed by connecting four sections of straight cloth and four elbows at intervals, wherein the elbows are of a U-shaped integral structure, two pieces of edge cloth and one piece of middle cloth or connecting cloth of a shed cloth elbow in the prior art are made into a whole, and the integral shed cloth structure is formed by the integral shed cloth and the straight cloth; its simple structure, monocycle shed cloth does not have the seam, and elbow structural firmness is high, and processing method is simple, during the use, uses the sewing thread to connect into the shed cloth through sewing machine with polycycle shed cloth and constitutes to be applied to the through passage, the sewing work load that has significantly reduced, has improved product performance.
Description
The technical field is as follows:
the invention belongs to the technical field of rail transit equipment, and particularly relates to integral shed cloth for a through passage, which can solve the problems of water seepage, water leakage and thread cutting at an elbow of the shed cloth for the through passage and shed cloth abrasion caused by sewing threads.
Background art:
the through passage is an internal passage which allows passengers to freely walk from one carriage to another carriage of the rail transit vehicle and enables the passengers to feel safe and comfortable, the shed cloth is one of important components of the through passage, the shed cloth of the through passage comprises two parts, namely an elbow and a transverse cloth, the transverse cloth can be freely stretched, but the elbow part cannot be stretched to the degree of straight cloth due to self structural problems, the stretching amount of the shed cloth is mainly realized by the elasticity of the shed cloth, and if the stretching amount of the sewing lap joint part is small, the sewing lap joint part can be easily torn, so that the service life of the whole shed cloth is influenced. The structure of the shed cloth determines the sound insulation, heat insulation and waterproof performance of the through passage, the capability of the vehicle when the vehicle moves through a small curve is important in the structural performance of the shed cloth, particularly the elbow part of the shed cloth plays an important role, the elbow part of the shed cloth is positioned at the transition part of the shed cloth, the part of the vehicle which is greatly influenced by stress when passing through the curve is also the part of the shed cloth which is most easily damaged, and therefore the elbow structural design of the shed cloth plays a key role.
Canopy cloth elbow structure in the existing market all adopts three-piece canopy cloth lapped sewing mode to make, for example: the chinese patent 201822140833.4 discloses a through passage shed cloth bend device, the main structure of which comprises a first intermediate cloth, a second intermediate cloth, a first transition section, a second transition section, an outer cloth and an inner cloth; the top sewing forms the lambdoidal intermediate cloth structure after the first intermediate cloth of the J-shaped structure and the straight line end of the second intermediate cloth are folded, the lower end part of the lambdoidal intermediate cloth structure is a first transition section of an arc sheet structure, the upper end part of the lambdoidal intermediate cloth structure is a second transition section of a U-shaped structure, the first intermediate cloth, the second intermediate cloth, the first transition section and the second transition section form an integral structure, the hook end of the first intermediate cloth is lapped with the outer side cloth and then sewn, and the hook end of the second intermediate cloth is lapped with the inner side cloth and then sewn. Tarpaulins are also segmented structures, such as: chinese patent 201810631931.X discloses a four-section type shed cloth unit, including top shed cloth, bottom shed cloth and two side shed cloths, top shed cloth is the U-shaped of invering approximately, bottom shed cloth is the U-shaped approximately, the both ends of top shed cloth are sewed up with the tip of the side shed cloth of both sides respectively and are connected, the both ends of bottom shed cloth are sewed up with the tip of the side shed cloth of both sides respectively and are connected, the department of sewing up still is equipped with the sealing layer, improve the shed cloth unit of traditional eight-section formula into four-section type shed cloth unit, set up the sealing layer between the department of sewing up of two sections shed cloth.
The shed cloth has the defects of complicated sewing process mode, more sewing lap joint parts, water seepage and water leakage, and increases the probability of the shed cloth being torn by the sewing threads and the shed cloth being abraded by the sewing threads in the repeated stretching process, thereby shortening the service life of the shed cloth. Therefore, an integral elbow is developed to solve the problems of water seepage, water leakage and thread cutting at the elbow of the through shed cloth and the abrasion of the shed cloth caused by sewing threads.
The invention content is as follows:
the invention aims to overcome the defects in the prior art, and designs the integral shed cloth for the through passage, which can solve the problems of water seepage, water leakage, line opening and abrasion, thereby prolonging the service life of the shed cloth.
In order to achieve the purpose, the integral shed cloth for the through passage is an integral annular structure formed by connecting four sections of straight cloth and four bends at intervals.
The elbow related by the invention is of a U-shaped integrated structure.
The material of the straight cloth related by the invention is the same as that of the elbow, and the thickness of the straight cloth is the same as that of the elbow.
Compared with the prior art, the two pieces of edge cloth and the middle cloth or the connecting cloth of the shed cloth elbow in the prior art are made into a whole, and the integral shed cloth structure is formed by the two pieces of edge cloth and the middle cloth or the connecting cloth and the straight cloth, the problem of sewing lap joints does not exist in the single-ring shed cloth, the sewing process mode of the shed cloth is simplified, the problems of water seepage and water leakage at the shed cloth elbow, shed cloth thread cutting and shed cloth abrasion caused by sewing threads are solved, and the service life of the shed cloth is prolonged; its simple structure, monocycle shed cloth does not have the seam, and elbow structural firmness is high, and processing method is simple, during the use, uses the sewing thread to connect into the shed cloth through sewing machine with polycycle shed cloth and constitutes to be applied to the through passage, the sewing work load that has significantly reduced, has improved product performance.
Description of the drawings:
fig. 1 is a schematic diagram of the principle of the main structure of the present invention.
Fig. 2 is an external view of the elbow according to the present invention.
Figure 3 is a schematic cross-sectional view of a bend according to the present invention.
Figure 4 is a 3D schematic of an elbow to which the present invention relates.
FIG. 5 is a schematic view of the main structure of the shed cloth according to the present invention.
FIG. 6 is an enlarged view of a part of the structure of the shed cloth according to the present invention.
The specific implementation mode is as follows:
the invention is further described by way of example with reference to the accompanying drawings.
Example 1:
the integral shed cloth for the through passage related to the embodiment is an integral rectangular or trapezoidal annular structure formed by connecting four sections of straight cloth 1 and four elbows 2 at intervals; the straight cloth 1 is a linear structure with a U-shaped section, and the outer edge of the straight cloth is linear; the elbow 2 is an arc-shaped structure with a U-shaped section, the outer edge of the elbow is arc-shaped, and the inner side end of the U-shaped elbow is longer than the outer side end of the U-shaped elbow.
When the integral shed cloth for the through passage according to the embodiment is used, a set number of shed cloths are connected by a sewing machine by using sewing threads according to design requirements to form the shed cloth assembly for the through passage.
