Description

Technical Field

[0001] This utility model belongs to the field of railway existing line signal retrofitting technology, and in particular relates to a small power supply that facilitates railway signal construction. Background Technology

[0002] The market share of existing line signal upgrades in railway signal construction is increasing. However, factors such as high traffic density, significant interference, and short maintenance windows on existing lines greatly affect the interlocking continuity testing of signal systems. This is especially true in signal upgrade projects that reuse existing power supply panels. For safety reasons, equipment management units only allow the insertion of existing equipment power supplies for interlocking tests within the maintenance window. A 30-minute allowance must be reserved before the test is completed to allow for recovery time. This constantly compresses the testing time for new equipment, increases the chance of errors, and requires waiting for the next maintenance window, thus extending the construction schedule. Utility Model Content

[0003] In view of the above situation and to overcome the shortcomings of the existing technology, this utility model provides a small power supply that is convenient for railway signal construction.

[0004] The technical solution adopted by this utility model is as follows: a small power supply for railway signal construction, including a mobile car body, a power supply screen body and a positioning mechanism; the mobile car body has a corresponding support platform; the power supply screen body is configured on the support platform, and has an internally divided installation chamber, with the front and rear sides of the installation chamber being open and equipped with protective doors; the positioning mechanism is mounted on both sides of the power supply screen body, and can be raised and lowered on both sides of the mobile car body to perform corresponding positioning operations.

[0005] Furthermore, the mechanism includes a support plate mounted on the top of the power supply panel body, with both ends of the support plate extending to both sides of the power supply body; lifting units, respectively disposed at the bottom of both ends of the support plate, for lifting the positioning unit; and a positioning unit, disposed at the lifting end of the lifting unit, for positioning the moving vehicle body.

[0006] Furthermore, the positioning unit includes a positioning side plate, which is configured on the telescopic end of the lifting unit and located on both sides of the power supply panel body; and a positioning base plate, which is configured on the bottom of the positioning side plate via a connecting rod and has corresponding support working length and width.

[0007] Furthermore, the top of the positioning side plate is provided with a winding post, and the winding posts are arranged at intervals along the length direction of the positioning side plate.

[0008] Furthermore, baffles are respectively arranged between the front end and the rear end of the two positioning side plates. The baffles can be inserted and removed between the corresponding ends of the two positioning side plates, and the baffles have corresponding sliding damping between them and the positioning side plates along their insertion and removal direction.

[0009] Furthermore, the front end of the positioning side plate is bent outward by a predetermined distance to form a limiting part.

[0010] Furthermore, handrails are rotatably arranged between the rear ends of both sides of the power supply screen body.

[0011] The beneficial effects of this utility model after adopting the above structure are as follows: This utility model proposes a small power supply that facilitates railway signal construction.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0019] like Figures 1-3 As shown, a small power supply for railway signal construction includes three parts: a mobile vehicle body 1, a power supply panel body 2, and a positioning mechanism for positioning the entire device. The mobile vehicle body 1 has a corresponding support platform. The power supply panel body 2 is mounted on the support platform and has an internally divided installation chamber 4. The front and rear sides of the installation chamber are open and equipped with protective doors 3. Furthermore, handrails 13 are rotatably mounted between the rear ends of both sides of the power supply panel body 2. The connection between the handrails 13 and the lateral parts of the power supply panel body 2 is a damped rotatable connection with corresponding rotational damping. When moving the device, the handrails 13 are rotated to a suitable position, and after reaching the suitable position, the handrails 13 can be lifted. The positioning mechanism is used to position the entire device when it is moved to a suitable working position. It is also equipped with a baffle 11 that matches the positioning mechanism. The baffle 11 can be adjusted according to the length of the front and rear ends of the power supply panel body 2, positioning it between the front and rear ends of the power supply panel body 2, reducing swaying at the hinged joints of the front and rear ends of the power supply panel body 2 during movement and reducing the probability of loose internal wiring.

[0020] In some preferred embodiments, the power supply panel body 2 can be configured with various modular power supply boxes to output multiple control power supplies for interlocking tests, such as DC24V, DC48V, AC220V, etc., enabling the conduction of new signal interlocking continuity tests in existing signal machinery rooms without affecting train operation, ensuring zero failures in the circuit modification part when connecting to existing signal equipment. Furthermore, the power supply panel body 2 can also be configured with mini digital display signal indicator lights to display AC and DC voltage, current, frequency, etc. In addition, the power supply panel body 2 also has a wind-cooling heat dissipation structure, etc. The above are configurations of existing technology based on actual conditions, and will not be described in detail here.

[0021] In some preferred embodiments, the positioning mechanism is mounted on both sides of the power supply panel body 2 and can be raised and lowered on both sides of the mobile vehicle body 1 to perform corresponding positioning operations. The positioning mechanism includes a support plate 5 mounted on the top of the power supply panel body 2, with both ends of the support plate 5 extending to both sides of the power supply body; lifting units, respectively disposed at the bottom of both ends of the support plate 5, for raising and lowering the positioning units; the lifting units can be telescopic push rods 6, electrically driven or connected to a hydraulic working system; and positioning units, disposed at the lifting end of the lifting units, for positioning the mobile vehicle body 1.

[0022] Specifically, the positioning unit includes a positioning side plate 7, which is configured on the telescopic end of the lifting unit and located on both sides of the power supply screen body 2; and a positioning base plate 8, which is configured on the bottom of the positioning side plate 7 via a connecting rod 9, and has corresponding support working length and width.

[0023] Based on the above embodiments, a winding post 10 can be configured at the top of the positioning side plate 7. The winding post 10 is arranged at intervals along the length of the positioning side plate 7. This allows the cables to be separated and positioned during relevant tests in advance, making it easier to distinguish them in time and avoiding cable tangling.

[0024] It should be noted that the baffles 11 mentioned in the above embodiments are respectively disposed between the front end and the rear end of the positioning side plates 7 on both sides of the power supply screen body 2. The baffles 11 can be inserted and removed between the corresponding ends of the two positioning side plates 7, and the baffles 11 have corresponding sliding damping between them and the positioning side plates 7 along their insertion and removal direction. The baffles 11 can be inserted and removed at predetermined positions on the two positioning side plates 7. A sliding slot matching the positioning side plate 7 is opened at the corresponding position at the bottom of the baffles 11, so that the baffles 11 can be inserted into the positioning side plate 7. A positioning upper plate can be configured on the upper side of the positioning side plate 7 to increase the contact points with the front and rear protective doors 3 of the power supply screen body 2 and improve the positioning effect. In addition, the front end of the positioning side plate 7 is bent outward by a predetermined distance to form a limiting part 12, which is used to limit the baffles 11 and prevent them from sliding out of the positioning side plate 7 along the length direction of the positioning side plate 7.

[0025] The specific usage is as follows: The main body 2 of the power supply panel is easily moved on-site via the mobile vehicle 1. After moving to the corresponding working position, the baffle 11 is removed, and the telescopic push rod 6 is activated to push the positioning side plate 7 and positioning base plate 8 downwards until the positioning base plate 8 touches the ground, thereby adjusting the overall position of the device. After positioning is completed, the construction personnel use the main body 2 of the power supply panel to pre-connect the signal equipment, such as the signal light circuit, alarm circuit, track circuit, switch machine operation circuit, and indication circuit, to ensure that the existing signal equipment is connected and that the circuit modification part has zero faults.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. In summary, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
