Description

Technical Field

[0001] The utility model relates to the technical field of suspended load testing, in particular to a suspended load testing device for a hose joint. Background Art

[0002] The "Interim Technical Conditions for Nylon Hoses and Nylon Hose Connectors for Railway Passenger Cars" (TJ / CL430-2014) stipulates the performance requirements for nylon hose connectors. One of the performance requirements is the hanging load capacity of the connector. During the hanging load test, the hose connector that the manufacturer claims has hanging load performance needs to be fixed to a rigid structure, and a weight (30N) is hung on it. Then, it is placed in an oven at a temperature of 105±2℃ and baked for 48 minutes before being taken out. If the connector is normal without additional magnification or has no visible cracks with corrected vision, and there is no deformation that will affect the continued use of the accessory, it is considered to have passed the test.

[0003] Because the standard doesn't specify the specific structure of the suspension device, current suspension device structures vary widely. Some are designed for only a single hose connector. To fully utilize the oven, multiple suspension devices are placed inside the oven to test different hose connectors simultaneously, which is inconvenient. Furthermore, current tests typically connect the weight and the hose connector with a connecting rope tied between the connector's body and cover. This is inefficient and can easily cause stress on one side of the cover, or cause stress on the body to be applied while reducing the stress on the cover.

[0004] Therefore, it is necessary to improve the prior art to overcome the above defects. Utility Model Content

[0045] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0046] As used herein, the terms "comprise," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0047] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0048] like Figures 1 to 4 As shown, a hose connector suspension load test device according to a preferred embodiment of the present invention includes a support assembly 1 , a carrier plate 2 and a suspension assembly 4 .

[0049] The support assembly 1 can be made of high temperature resistant materials such as stainless steel or aluminum alloy.

[0050] The carrier plate 2 is connected to the support assembly 1. A suspension space 20 is defined below the carrier plate 2. The carrier plate 2 includes a plurality of mounting holes 21. The mounting holes 21 have different diameters. Mounting holes 21 of different diameters can be used to mount hose connectors 3 of different specifications. Therefore, the plurality of mounting holes 21 can accommodate hose connectors 3 of various specifications. Figure 1 In the illustrated embodiment, the diameters of the multiple mounting holes 21 are completely different, meaning no two mounting holes 21 have the same diameter. This allows for the placement of a wider variety of hose connectors 3 of varying specifications. In other embodiments, the multiple mounting holes 21 can be divided into multiple groups, each group containing mounting holes 21 of the same diameter. This allows multiple groups of hose connectors 3 of varying specifications to be placed on the carrier plate 2 for testing.

[0051] like Figure 4As shown, the hose connector 3 includes a body 30 and a cover 31. The body 30 includes an abutting portion 300 that abuts the upper surface 2a of the carrier plate 2 and a threaded portion 301 that extends through the mounting hole 21. The cover 31 is threadedly connected to the threaded portion 301 and is located below the carrier plate 2. Specifically, a portion of the threaded portion 301 is located below the lower surface 2c of the carrier plate 2. The upper surface 2a of the carrier plate 2 abuts the abutting portion 300 of the body 30, and the cover 31 is threadedly connected to the threaded portion 301 located below the lower surface 2c of the carrier plate 2.

[0052] The suspension assembly 4 includes a counterweight 40 and a first connecting rope 41. The first connecting rope 41 is connected between the counterweight 40 and the cover 31. The counterweight 40 is suspended in the suspension space 20 below the carrier 2 and is used to apply a downward force to the cover 31. The counterweight 40 can be, for example, a weight, and its mass can be adjusted as needed.

[0053] By providing a plurality of mounting holes 21 on the carrier plate 2 for placing hose connectors 3 of various specifications, multiple hose connectors 3 of various specifications can be simultaneously suspended on the carrier plate 2 for testing, thereby improving testing efficiency. Furthermore, the entire hose connector suspension load test device has a simple structure and low cost.

[0054] In some embodiments, the height position of the carrier plate 2 relative to the support assembly 1 is adjustable. The height of the carrier plate 2 can be adaptively adjusted according to the suspension space required by the first connecting rope 41 and the counterweight 40 of different lengths, so that the counterweight 40 is in a suspended state; in addition, the carrier plate 2 can change the center of gravity position of the hose connector suspension load test device, and the position of the carrier plate 2 can be made as low as possible while meeting the suspension conditions, which can improve the stability of the device during the baking process.

[0055] like Figure 1 and Figure 6 As shown, the support assembly 1 includes four brackets 10. The carrier plate 2 is rectangular, with its four corners corresponding to the four brackets 10. The brackets 10 include multiple through-holes 100 spaced apart along the height direction. The support assembly 1 includes fasteners 11 connected to the carrier plate 2. Fasteners 11 pass through through-holes 100 and are supported by the brackets 10, thereby securing the carrier plate 2 on the brackets 10. Fasteners 11 are located at the corners of the carrier plate 2. Optionally, at least one fastener 11 is provided at each of the four corners of the support assembly 1. To change the height of the carrier plate 2, simply select through-holes 100 at different heights to connect the fasteners 11 to the carrier plate 2.

[0056] In one embodiment, if Figure 7 and Figure 8As shown, a threaded hole 22 is provided at the position where the carrier plate 2 is connected to the fastener 11. The fastener 11 is fixed to the carrier plate 2 by a threaded connection. The fastener 11 is inserted into the through hole 100, and its head 110 abuts against the bracket 10, thereby fixing the carrier plate 2 to the bracket 10. Optionally, the fastener 11 is a bolt.

[0057] like Figure 11 As shown, the bracket 10 includes a first plate portion 101, a second plate portion 102 connected to the first plate portion 101 and perpendicular to each other, and a third plate portion 103 connected to the bottom ends of the first plate portion 101 and the second plate portion 102. The third plate portion 103 is arranged parallel to the carrier 2, and both are arranged horizontally. The first plate portion 101 and the second plate portion 102 are respectively arranged corresponding to the two side surfaces of the carrier 2, which can limit the horizontal position of the carrier 2. In the illustrated embodiment, the first plate portion 101 and the second plate portion 102 are both provided with a plurality of through holes 100 corresponding to each other. It is understandable that in other embodiments, the plurality of through holes 100 can also be provided only on the first plate portion 101 or the second plate portion 102.

[0058] In one embodiment, if Figure 7 and Figure 8 As shown, the through hole 100 is in the shape of a circular hole, and the fastener 11 can be passed through the through hole 100. In another embodiment, as shown in FIG. Figure 9 and Figure 10 As shown, the through hole 100 is in the shape of a long hole extending along the height direction, and the fastener 11 is in the shape of a column with a diameter smaller than the width of the through hole 100. Optionally, the fastener 11 is a pin.

[0059] When the four brackets 10 are relatively fixed, preferably, the through hole 100 is in the shape of a long hole extending in the height direction, and only the two opposite sides of the carrier plate 2 are provided with fasteners 11, such as Figure 12 As shown, the four brackets 10 are all connected to the same base plate 105, so that the four brackets 10 and the base plate 105 are fixed as a whole; since the through hole 100 is in the shape of an elongated hole, when installing the carrier plate 2, the tester can first tilt the carrier plate 2 and place the fastener 11 on one side of the carrier plate 2 into the elongated through hole 100, and then move the carrier plate 2 downward so that the fastener 11 on the other side of the carrier plate 2 is placed in the corresponding through hole 100, and then flatten the carrier plate 2 so that the bottom of the through hole 100 supports the fastener 11.

[0060] In some embodiments, as Figure 13 As shown, the first connecting rope 41 is tied to the threaded portion 301 and is located between the carrier plate 2 and the cover body 31. The other end of the first connecting rope 41 is connected to the counterweight 40. The counterweight 40 and the first connecting rope 41 are located in the suspension space 20. The counterweight 40 applies force to the cover body 31 through the first connecting rope 41.

[0061] In some embodiments, as Figure 3 and Figure 4 As shown, the suspension assembly 4 includes a first connecting ring 42 that is sleeved on the threaded portion 301, and the first connecting rope 41 is connected to the first connecting ring 42. The user can first connect and fix the first connecting rope 41 to the first connecting ring 42, then sleeve the first connecting ring 42 on the threaded portion 301 located below the carrier 2, and finally fix the cover body 31 to the threaded portion 301 located on the lower surface 2c of the carrier 2 through threaded connection. Since the first connecting rope 41 and the first connecting ring 42 only need to be connected once, they can be directly connected to the hose connector through the first connecting ring 42 later, without having to tie the first connecting rope 41 to the hose connector every time. This is beneficial to improving the connection efficiency of the suspension assembly 4 and the hose connector. When the first connecting ring 42 is connected to the first connecting rope 41 on one side, the cover body 31 will be subjected to tension on one side, and the force is uneven. Optionally, as Figures 14 to 16 As shown, a first connecting rope 41 is correspondingly tied to both sides of the first connecting ring 42, so that the counterweight 40 will be located directly below the cover body 31, and the force on the cover body 31 will be more even.

[0062] In some embodiments, as Figure 17 and Figure 18 As shown, a ring portion 420 is provided on each side of the first connecting ring 42, and the suspension assembly 4 includes two hook portions 43 connected to the first connecting rope 41. The first connecting rope 41 is hooked with the two ring portions 420 through the two hook portions 43, thereby making the connection between the counterweight 40 and the first connecting ring 42 more convenient, and the downward force is applied to the cover body 31 through the first connecting ring 42, so that the force on the cover body 31 is more uniform.

[0063] It is understandable that the number of the ring portions 420 is not limited to two, and may be three or four, for example. Preferably, they are symmetrically arranged.

[0064] In some embodiments, as Figure 19 and Figure 20 As shown, the suspension assembly 4 further includes a second connecting ring 45 connected to the first connecting ring 42 via a second connecting rope 44. The second connecting ring 45 is located below the hose connector 3. The second connecting rope 44 can be connected to the first connecting ring 42 or, when the first connecting ring 42 includes a ring portion 420, the second connecting rope 44 can be tied to the ring portion 420 of the first connecting ring 42. Optionally, as Figure 19 and Figure 20 In the embodiment shown, the device includes two second connecting ropes 44 symmetrically tied to the first connecting ring 42, the other ends of the two second connecting ropes 44 are connected to the second connecting ring 45, and the first connecting rope 41 is connected between the second connecting ring 45 and the counterweight 40. At this time, the counterweight 40 is directly below the hose connector 3, and the hose connector 3 is evenly stressed.

[0065] Further, such as Figure 21 and Figure 22 As shown, the suspension assembly 4 further includes a hook portion 43 connected to the first connecting rope 41 , and the first connecting rope 41 is hooked with the second connecting ring 45 through the hook portion 43 , thereby improving connection efficiency.

[0066] The number of second connecting ropes 44 is not limited, and multiple second connecting ropes 44 can share one second connecting ring 45, or each second connecting rope 44 can correspond to one second connecting ring 45. In some embodiments, Figure 21 and Figure 22 As shown, there are two second connecting ropes 44, which are symmetrically arranged and share a second connecting ring 45. The first connecting rope 41 is hooked with the second connecting ring 45 through the hook portion 43. The other end of the first connecting rope 41 is tied with a counterweight 40. At this time, the counterweight 40 is directly below the hose connector 3, thereby improving the uniformity of the force applied to the hose connector 3.

[0067] In other embodiments, Figure 23 and Figure 24 As shown, the suspension assembly 4 includes two second connecting rings 45, which are respectively connected to the ends of two second connecting ropes 44. The first connecting rope 41 is hooked with the two second connecting rings 45 at the same time through the hook 43. The other end of the first connecting rope 41 is connected to the counterweight 40. At this time, the counterweight 40 is directly below the hose connector 3, thereby improving the uniformity of the force on the hose connector 3.

[0068] The first connecting ring 42 and the second connecting ring 45 are both made of hard materials, for example, metal materials such as aluminum alloy and stainless steel, or high-temperature resistant plastic materials.

[0069] The above is only a specific implementation of the present invention, and any other improvements made based on the concept of the present invention are considered to be within the scope of protection of the present invention.
