Description

Technical Field

[0001] The present application relates to the technical field of maintenance equipment, and in particular to a contact network detection support device. Background Art

[0002] Railway workers often need to climb onto the roof of railway locomotives to perform maintenance work. In order to avoid electric shock accidents in the electrified high-voltage section of the railway locomotive, a high-voltage alarm device is generally installed on the roof of the locomotive to determine whether the contact network has electricity.

[0003] At present, high-voltage alarm devices generally use sensors to judge the size of the induced voltage to determine whether the contact network is energized. The installation position of the high-voltage alarm device on the locomotive is fixed. For different locomotives, the support height of the high-voltage alarm device also needs to be adjusted accordingly to ensure that the induced voltage is in the normal detection range.

[0004] In the related art, the height of the sensor is increased by adding washers or nuts to the mounting legs. However, when the induced voltage is small, more nuts and washers need to be installed, which makes the adjustment process inconvenient and inefficient. Utility Model Content

[0032] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0033] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0034] In the railway industry, in order to avoid personal injury caused by climbing to the top of the high-voltage network when it is energized, a high-voltage alarm device is installed at the top ladder of the locomotive. The high-voltage alarm device generally uses a set high-voltage sensor to receive the electromagnetic field signal of the high-voltage contact network on the roof, and transmits it to the host in the car for identification. It determines whether the contact network is energized by comparing the internal voltage and the induced voltage of the sensor.

[0035] For different locomotive models, the height of the locomotive roof will also change accordingly. During the locomotive maintenance and use process, since the high-voltage alarm device is directly fixed on the locomotive roof, the size of the induced electricity detected by the sensor will change with the change of the roof height. The detected induced electricity cannot be maintained in the normal working detection range, affecting the function of the high-voltage alarm device.

[0036] In the related art, in order to reduce the detection error caused by the change of induced electricity, the following two methods are generally used: by reducing the battery voltage of the high-voltage alarm device, or by increasing the height of the high-voltage alarm device. When the battery voltage is reduced, the overall power of the battery is reduced, and the battery needs to be replaced frequently; and when the height of the high-voltage alarm device is increased, nuts or washers are added to the mounting bolts of the sensor to increase the position of the sensor. When the induced voltage is low, the number of nuts or washers is large, the installation is cumbersome, and the adjustment is inconvenient.

[0037] Based on the above related technologies, the present application provides a contact network detection support device to improve the technical problem of the inconvenient adjustment of the support height of the above-mentioned high-voltage alarm device.

[0038] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0039] like Figure 1 and Figure 2 As shown, the present application provides a contact network detection support device for supporting and detecting a voltage detection component of the contact network above the roof of a locomotive.

[0040] The contact network detection bracket includes a fixed bracket 100, an adjustable bracket 200 and a locking assembly 300, wherein the fixed bracket 100 is used to be fixed on the roof of a locomotive; the adjustable bracket 200 is slidably connected to the fixed bracket 100, and the voltage detection component is fixed on the adjustable bracket 200; the locking assembly 300 includes a locking pin arranged on the fixed bracket 100 and the adjustable bracket 200, and an adjusting member 350 elastically sleeved on the locking pin, the adjusting member 350 and the locking pin jointly lock the fixed bracket 100 and the adjusting bracket 200; the adjusting member 350 is configured to be displaced relative to the locking pin under the drive of an external force to release the locking state of the adjustable bracket 200 and the fixed bracket 100.

[0041] It can be seen from the above description that the contact network detection support device provided by the present application, since the voltage detection component is fixed on the adjustment bracket 200, when the adjustment member 350 of the locking assembly 300 is displaced under the drive of an external force, the adjustment bracket 200 can slide relative to the fixed bracket 100, and the sliding process is convenient for adjusting the distance between the voltage detection component and the contact network above the locomotive roof, and after the adjustment is completed, the locking assembly 300 is used to re-lock the fixed bracket 100 and the adjustment bracket 200. The device can be widely used in locomotives of different models, and the adjustment process is convenient and quick, which is conducive to improving work efficiency.

[0042] It should be noted that the above-mentioned voltage detection component can adopt a high-voltage alarm device for detecting the live state of the contact network in the relevant technology. Exemplarily, the voltage detection component adopts the NDJC-3 type high-voltage alarm device, which includes a voltage alarm device host, a roof high-voltage induction receiver, and a roof door status detection travel switch. When the roof high-voltage induction receiver receives the electromagnetic field signal of the contact network, the host performs signal recognition. If the contact network is live, it filters, adjusts, and amplifies it to send out an audible and visual alarm signal to warn the operator. Here, the induced voltage of the NDJC-3 type high-voltage alarm device after adjusting the height should be maintained at 6-10V to ensure normal detection of the live state of the contact network. Of course, the voltage detection component can also adopt other types of high-voltage alarm devices, which will not be repeated below.

[0043] like Figure 1 As shown, the fixing bracket 100 includes a mounting portion 110 for fixing to the roof of a locomotive, and a first extension portion 120 arranged on one side of the mounting portion 110; the adjusting bracket 200 includes a bearing portion 210 for mounting a voltage detection component, and a second extension portion 220 arranged on one side of the bearing portion 210; the second extension portion 220 is slidably engaged with the first extension portion 120.

[0044] Specifically, the mounting portion 110 is in the shape of a flat plate, and at least two mounting holes are arranged at intervals on the mounting portion 110. The fixing bracket 100 is fixed to the roof of the locomotive by a first fastener penetrating the mounting holes. Generally, the mounting portion 110 and the first extension portion 120 are integrally formed, and the first extension portion 120 is bent relative to the mounting portion 110 through processing. After the first extension portion 120 is bent, it extends in a direction away from the roof of the locomotive.

[0045] Similarly, the bearing part 210 is in the shape of a flat plate, and at least two positioning holes are arranged at intervals on the bearing part 210. The voltage detection component is fixed to the adjustment bracket 200 by a second fastener penetrating the positioning holes. Generally, the bearing part 210 and the second extension part 220 are integrally formed, and the second extension part 220 is bent relative to the bearing part 210 through processing. After the second extension part 220 is bent, it is slidably engaged with the first extension part 120, and the sliding engagement method between the two is not absolutely limited. For example, a limiting snap ring is jointly sleeved on the first extension part 120 and the second extension part 220, and under the constraint of the limiting snap ring, the second extension part 220 slides along the length direction of the first extension part 120.

[0046] In addition, the first fastener and the second fastener mentioned above can be fastening bolts. The fixing bracket 100 is fixed to the roof of the locomotive by the first fastener as a fixing base without the need for other height adjustment operations. The voltage detection component is fixed to the adjustment bracket 200 by the second fastener and slides in the height direction synchronously with the adjustment bracket 200.

[0047] Furthermore, at least two locking assemblies 300, first extension portions 120 and second extension portions 220 are each provided, each first extension portion 120 is located on the same side of the mounting portion 110, each second extension portion 220 is located on the same side of the bearing portion 210, and the locking assemblies 300, first extension portions 120 and second extension portions 220 are provided correspondingly.

[0048] Reference Figure 1 and Figure 2 As shown, two first extension portions 120 are respectively provided on the same side of the mounting portion 110, and the first extension portions 120 are disposed at both ends of the mounting portion 110; two second extension portions 220 are respectively provided on the same side of the bearing portion 210, and the second extension portions 220 are disposed at both ends of the bearing portion 210; the length of the mounting portion 110 is slightly smaller than the length of the bearing portion 210; the two first extension portions 120 are clamped between the two second extension portions 220; and the mounting portion 110, the bearing portion 210, the first extension portions 120 and the second extension portions 220 together form a rectangular frame.

[0049] In the above embodiment, the two first extensions 120 are located inside the two second extensions 220. As an alternative embodiment, the length of the bearing portion 210 is slightly smaller than the length of the mounting portion 110, and the two first extensions 120 are located outside the two second extensions 220. Of course, multiple first extensions 120 can also be arranged on the same side of the mounting portion 110, and multiple second extensions 220 can be arranged on the same side of the bearing portion 210, as long as the first extensions 120 and the second extensions 220 are arranged one by one. Here, the other embodiments of the present application are described with the solution that the first extension 120 is located inside the second extension 220, and no further description is given.

[0050] The first extension portion 120 and the mounting portion 110 are disposed perpendicularly to each other, and the second extension portion 220 and the bearing portion 210 are disposed perpendicularly to each other. The first extension portion 120 and the second extension portion 220 are fitted and abutted against each other, and are fixed to form a lock by a locking pin penetrating at least one of the first extension portion 120 and the second extension portion 220. In some embodiments, the first extension portion 120 is inclined at a certain angle relative to the mounting portion 110, and the second extension portion 220 is inclined at a certain angle relative to the bearing portion 210. This application does not make an absolute limitation on this, as long as it is ensured that the adjustment bracket 200 can be close to or away from the motorcycle roof when sliding on the fixed bracket 100.

[0051] In some embodiments, the first extension portion 120 is provided with a guide groove 122 extending along the length direction, and the second extension portion 220 is provided with a convex ridge extending along the length direction. The guide groove 122 and the convex ridge are interlocked and snap-fitted. The interlocking guide groove 122 and the convex ridge can limit the sliding path of the second extension portion 220 and prevent the second extension portion 220 from separating from the first extension portion 120 during the height adjustment process.

[0052] Providing at least two first extension portions 120 and at least two second extension portions 220 can make the force between the fixed bracket 100 and the adjustable bracket 200 more uniform, thereby effectively improving the sliding connection stability between the adjustable bracket 200 and the fixed bracket 100.

[0053] Reference Figure 1 As shown, in some embodiments, the first extension portion 120 is provided with a first slot 121 along the length direction, the second extension portion 220 is provided with a second slot 221 along the length direction, and the locking pin passes through the first slot 121 and the second slot 221. In order to further enhance the sliding and clamping stability effect between the first extension portion 120 and the second extension portion 220, the first slot 121 and the second slot 221 are mutually embedded, and when the second extension portion 220 slides relative to the first extension portion 120, it slides along the direction of the first slot 121 and the second slot 221.

[0054] Reference Figure 1and Figure 3 As shown, in some embodiments, the locking pin includes a pin rod 310 and a first stop block 320 and a second stop block 330 respectively disposed at both ends of the pin rod 310 . The first stop block 320 is located on a side of the adjusting member 350 away from the fixed bracket 100 , and the fixed bracket 100 and the adjusting bracket 200 are clamped between the adjusting member 350 and the second stop block 330 .

[0055] Here, the first stop block 320 at one end of the pin rod 310 is fixedly connected to the pin rod 310, and the second stop block 330 at the other end is detachably connected to the pin rod 310. For example, the second stop block 330 and the pin rod 310 are threadedly connected. During assembly, the second stop block 330 is first removed from the pin rod 310. After the pin rod 310 passes through the first slot 121 and the second slot 221, the second stop block 330 and the pin rod 310 are re-threadedly connected. There is no need to remove the second stop block 330 for the subsequent height adjustment process.

[0056] like Figure 3 As shown, the locking assembly 300 also includes an elastic member 340 mounted on the pin rod 310, and the two ends of the elastic member 340 are respectively abutted against the adjusting member 350 and the adjusting bracket 200; the elastic member 340 is configured to drive the adjusting member 350 to push toward the second stop block 330, so that the fixed bracket 100 and the adjusting bracket 200 are clamped between the adjusting member 350 and the second stop block 330.

[0057] The above-mentioned elastic member 340 can be a spring, which is sleeved in the pin rod 310, with one end abutting against the first stop block 320 and the other end abutting against the adjusting member 350. Since the first extension portion 120 and the second extension portion 220 are arranged to slide in close proximity, the elastic force of the spring pushes the adjusting member 350 toward the second stop block 330, and the clamping force between the adjusting member 350 and the second stop block 330 is used to clamp the first extension portion 120 and the second extension portion 220, thereby forming a locking mechanism for the fixed bracket 100 and the adjustable bracket 200.

[0058] In some embodiments, a side of the adjusting bracket 200 facing the adjusting member 350 and a side of the fixing bracket 100 facing the second stopper 330 are both provided with an anti-slip layer 123 .

[0059] The anti-slip layer 123 can be made of rubber material, for example, natural rubber material or artificial synthetic materials such as EPDM and chloroprene rubber. The anti-slip layer 123 can be adhered to the fixed bracket 100 and the adjustable bracket 200. The adjusting member 350 and the second stopper 330 respectively push the anti-slip layer 123 on the adjacent side, and the anti-slip layer 123 is used to ensure the locking and clamping effect of the adjusting member 350 on the fixed bracket 100 and the adjustable bracket 200.

[0060] As an alternative embodiment, the surface of the anti-slip layer 123 has uniform raised particles. The side of the adjusting member 350 facing the adjusting bracket 200 and the side of the second stopper 330 facing the fixing bracket 100 are also provided with the anti-slip layer 123. This setting can further enhance the locking and clamping effect of the locking assembly 300 on the fixing bracket 100 and the adjusting bracket 200.

[0061] It should be noted that in some embodiments, the first slot 121 or the second slot 221 can be omitted. When the first slot 121 is omitted, the pin rod 310 is threaded through the second slot 221 and abuts against the side end face of the first extension portion 120. When the second slot 221 is omitted, the pin rod 310 is threaded through the first slot 121 and abuts against the side end face of the second extension portion 220. Since the first extension portion 120 and the second extension portion 220 are fitted and slidably clamped, the abutting force of the pin rod 310 can prevent the second extension portion 220 from sliding relative to the first extension portion 120.

[0062] Reference Figure 4 As shown, in some embodiments, neither the first slot 121 nor the second slot 221 is provided. The locking pin is provided at the edge side of the first extension portion 120 and the second extension portion 220 and is in a "U" shape. The adjusting member 350 and the second stopper 330 clamp the edges of the first extension portion 120 and the second extension portion 220 and slide along the edges of the first extension portion 120 and the second extension portion 220 in the contact locking state.

[0063] As Figure 1 As shown, in some embodiments, through holes 111 for passing the wire harness of the voltage detection component are provided on both the mounting portion 110 and the bearing portion 210. Generally, the position and number of the through holes 111 are determined according to the actual position and number of the wire harness of the voltage detection component. In the embodiments of the present application, no absolute limitation is made in this regard.

[0064] It should be noted that the number of the locking assemblies 300 can be flexibly set. For example, a locking assembly 300 is provided on each of the first extension portion 120 and the second extension portion 220 that are slidably clamped arbitrarily, or a locking assembly 300 is provided only on a set of the first extension portion 120 and the second extension portion 220 that are slidably clamped. Of course, the more the number of the locking assemblies 300, the better the locking and fixing effect on the fixing bracket 100 and the adjusting bracket 200. For different implementation scenarios, as long as the fixing bracket 100 and the adjusting bracket 200 can be firmly locked and fixed.

[0065] Exemplarily, in the contact network detection support device of the present application, the dimensional specifications are set as follows: the length of the mounting portion 110 is 150 mm, the length of the first extension portion 120 is 200 mm, the length of the guide groove 122 is 100 mm, the length of the bearing portion 210 is 156 mm, and the length of the second extension portion 220 is 200 mm.

[0066] An exemplary use process of the contact network detection support device of the present application is as follows:

[0067] First, the fixing bracket 100 is fixed to the corresponding position of the motorcycle roof, and is fastened and connected by a first fastener penetrating the mounting hole on the mounting portion 110 and the motorcycle roof. The voltage detection component is fixed to the bearing portion 210 of the adjustment bracket 200, and is fastened and connected by a second fastener penetrating the positioning hole on the bearing portion 210 and the voltage detection component. Then, the adjustment bracket 200 is slidably connected to the fixing bracket 100. The sliding connection between the adjustment bracket 200 and the fixing bracket 100 can be adopted. Figure 1 The frame structure is formed in the frame structure, and the guide groove 122 of the first extension part 120 and the convex ridge of the second extension part 220 are used to limit the disengagement of the adjusting bracket 200; the second stopper 330 of the locking pin is removed, and after the pin rod 310 passes through the first slot 121 and the second slot 221, the second stopper 330 is reassembled. At this time, under the elastic force of the elastic member 340, the adjusting member 350 and the second stopper 330 elastically clamp the first extension part 120 and the second extension part 220, lock the fixing bracket 100 and the adjusting bracket 200, and extend one end of the wiring harness of the voltage detection component through the mounting part 110 into the locomotive to connect the locomotive central control, and the other end of the wiring harness passes through the bearing part 210 and extends out of the adjusting bracket 200 to detect the charged state of the contact network.

[0068] When it is necessary to adjust the height of the voltage detection component, the adjusting member 350 is manually moved in a direction away from the second stop block 330, the elastic member 340 is compressed, the distance between the adjusting member 350 and the second stop block 330 increases, and the contact is locked on the fixed bracket 100 and the adjusting bracket 200. Keeping this state, the adjusting bracket 200 can move up or down freely. When it is moved to a suitable height, the adjusting member 350 is released. Under the elastic action of the elastic member 340, the adjusting member 350 pushes the second extension portion 220 again, and the adjusting member 350 and the second stop block 330 are clamped and locked to the fixed bracket 100 and the adjusting bracket 200.
