Abstract
Description
Technical Field
[0001] This utility model relates to the field of track construction warning technology, and in particular to a warning device for track vehicle maintenance sites. Background Technology
[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.
[0003] Rail vehicle maintenance is a core component of ensuring the safe and efficient operation of railway transportation. This work typically takes place on the tracks at depots or mainline maintenance bases, involving the inspection, maintenance, and repair of equipment on rail vehicles. To provide clear and unambiguous warnings to other vehicles or personnel at a distance, directional warning lights are usually used, especially double-sided (e.g., red / yellow) directional lights, to indicate the location of the work area or obstacles and prevent collisions.
[0004] However, existing double-sided directional lights are often designed to be bulky or have complex mounting bases in pursuit of stability, making them inconvenient to carry and deploy. On the other hand, lightweight directional lights designed for portability often have problems such as being easy to tip over and having poor wind resistance. They are prone to failure in the airflow brought by passing trains or in strong winds, and cannot reliably fulfill their duty of continuous warning. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned shortcomings by providing a warning device for the maintenance site of rail vehicles.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a warning device for railway vehicle maintenance sites, comprising a double-sided directional light body for warning at railway vehicle maintenance sites, and further comprising: A wheel stop, adapted and installed on one side of the track, is used to prevent the rail vehicle from undergoing unexpected displacement. The wheel stop is provided with a fixing mechanism for clamping on both sides of the track. The connecting assembly includes a handle horizontally disposed through the wheel stop and connected to the body of the double-sided directional light, and a rotating sleeve disposed outside the handle and having the same length as the width of the wheel stop. The rotating sleeve is provided with a belt drive assembly, which is used to drive the fixing mechanism to fix the wheel stop to both sides of the track during the rotation of the rotating sleeve.
[0007] Furthermore, the fixing mechanism includes two clamping plates disposed on the end face of the wheel stop and symmetrically distributed on the left and right, a screw and a guide rod disposed on the two clamping plates and distributed back and forth along the length direction of the wheel stop, the two ends of the screw and corresponding positions on the two clamping plates are fitted with internal thread sleeves, and the two ends of the guide rod and corresponding positions on the two clamping plates are fitted with guide sleeves.
[0008] Furthermore, a connecting ring adapted for rotatable connection is provided on the handle corresponding to the end of the dual-sided directional light body, and the connecting ring is fixed to the bottom surface of the dual-sided directional light body.
[0009] Furthermore, a limiting strip is provided on one side of the circumferential surface of the handle, and a limiting groove is provided on the inner wall of the rotating sleeve to accommodate the horizontal insertion of the limiting strip; The handle is moved along the length of the limiting groove, causing the double-sided directional light body to move to the position between the two tracks.
[0010] Furthermore, the wheel stop is provided with a mounting groove at the position corresponding to the rotating sleeve, and the rotating sleeve is rotatably connected within the mounting groove.
[0011] Furthermore, the belt drive assembly includes a first pulley disposed in the mounting groove and sleeved on the outer wall of the rotating sleeve, and a second pulley disposed on the outer wall of the screw, wherein a drive belt is disposed on the first pulley and the second pulley; Driven by the rotation of the handle, the rotating sleeve is transmitted by the transmission belt, which in turn drives the screw to rotate.
[0012] The beneficial effects of this utility model are reflected in: This invention, through the combination of the double-sided directional light body and the wheel stop, and the setting of the fixing mechanism, eliminates the need for the double-sided directional light body to rely on its own bulky base or counterweight for stability. Its stability stems from the rigid connection with the wheel stop, which is clamped to the track by the fixing mechanism. This provides the double-sided directional light body with a "track-level" stable foundation, capable of withstanding the strong airflow generated when rail vehicles pass and the effects of strong winds, thus ensuring the stable warning function of the double-sided directional light. Furthermore, through the setting of the fixing mechanism, handle, rotating sleeve, and belt drive assembly, the rotating sleeve can be driven to rotate simultaneously when the operating handle is turned. This allows the fixing mechanism installed on the corresponding track end face of the wheel stop via the belt drive assembly to effectively fix both sides of the track, thereby achieving adaptive clamping fixation on both sides of the track to adapt to fixing on both sides of tracks with different thicknesses.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0016] Please see Figure 1-6 This utility model discloses a warning device for railway vehicle maintenance sites, including a double-sided directional light body 1 for warning at railway vehicle maintenance sites, and further comprising: The wheel stopper 2 is adapted to be installed on one side of the track to prevent the rail vehicle from undergoing unexpected displacement. The wheel stopper 2 is provided with a fixing mechanism 3 for clamping on both sides of the track. The connecting assembly includes a handle 4 horizontally extending through the wheel stop 2 and connected to the double-sided directional light body 1, and a rotating sleeve 5 located outside the handle 4 and having the same width as the wheel stop 2. The rotating sleeve 5 is provided with a belt drive assembly 6, which is used to drive the fixing mechanism 3 to fix the wheel stop 2 to both sides of the track during the rotation of the rotating sleeve 5.
[0017] In practice, by combining the double-sided directional light body 1 with the wheel stopper 2 using the handle 4, the wheel stopper 2 can be fixed on one side of the track. Then, by using the handle 4 to adjust the horizontal distance between the double-sided directional light body 1 and the wheel stopper 2 in a horizontal pulling manner, the installation position of the double-sided directional light body 1 can be determined. This allows the double-sided directional light body 1 to play an effective warning role during the construction of rail vehicles and achieves a stable fixing effect for the double-sided directional light body 1. When placing the wheel stopper 2, the workers need to operate the handle 4 that is horizontally installed on the wheel stopper 2 from the outside of the rail vehicle to push the wheel stopper 2 in, which effectively ensures personal safety. The placement of the wheel stopper 2 on a rail can effectively limit the wheel at that position and prevent the rail vehicle from moving unexpectedly, so that the rail vehicle stops precisely at a certain position, which can ensure the accuracy of the operation and the quality of construction. Furthermore, by using the rotating sleeve 5 installed outside the handle 4 and the belt drive assembly 6 installed on the rotating sleeve 5, the structure included in the fixing mechanism 3 installed on the corresponding track end face of the wheel stop 2 can be driven by the belt drive assembly 6 during the rotation of the rotating sleeve 5 to clamp and fix both sides of the track, so that the wheel stop 2 is further stably fixed on one side of the track.
[0018] In one embodiment, the fixing mechanism 3 includes two clamping plates 31 symmetrically distributed on the end face of the wheel stopper 2, a screw 32 and a guide rod 33 distributed on the two clamping plates 31 and along the length of the wheel stopper 2. The screw 32 has internal threaded sleeves 34 fitted at corresponding positions on the two clamping plates 31 at both ends, and guide sleeves 35 fitted at corresponding positions on the two clamping plates 31 at both ends of the guide rod 33. With this design, the internal threaded sleeves 34 and guide sleeves 35 welded to the clamping plates 31 at their respective front and rear positions, when a force is applied to rotate the screw 32 fitted inside the internal threaded sleeve 34, the two clamping plates 31 mounted on both sides of the lower end face of the wheel stopper 2 will move in opposite directions or away from each other under the guidance and limitation of the guide rods 33 fitted inside the guide sleeves 35. This allows the two clamping plates 31 to be fitted and fixed on both sides of rails of different thicknesses, achieving a stable fixing effect for the wheel stopper 2 on one side of the rail.
[0019] Additional notes: The internal threaded sleeve 34 and the guide sleeve 35 are respectively welded to the front and rear sides of the clamping plate 31, and the outside of the screw 32 is threadedly connected to the internal threaded sleeve 34, while the outside of the guide rod 33 is slidably connected to the guide sleeve 35. The screw 32 has two sections with opposite thread directions, which allows the clamping plates 31 connected by the internal thread sleeve 34 on both sides of the screw 32 to move towards or away from each other; The screw 32 has a self-locking structure.
[0020] In one embodiment, a connecting ring 7 is provided on the handle 4 at the end corresponding to the end of the dual-sided directional light body 1 for rotatable connection. The connecting ring 7 is fixed to the bottom surface of the dual-sided directional light body 1. With this design, by welding the connecting ring 7 to the bottom surface of the dual-sided directional light body 1 and by slotting the connecting ring 7 inside for rotatable connection with the handle 4, the dual-sided directional light body 1 will not be flipped when the handle 4 is rotated, and it can move independently of the dual-sided directional light body 1.
[0021] It should be noted that a pin is installed at a position where the connecting ring 7 is connected to the handle 4 to limit the further rotation of the double-sided directional light body 1.
[0022] In one embodiment, a limiting strip 41 is provided on one side of the circumferential surface of the handle 4, and a limiting groove 51 is provided on the inner wall of the rotating sleeve 5 to accommodate the horizontal passage of the limiting strip 41. The handle 4 is moved along the length of the limiting groove 51, causing the double-sided directional light body 1 to move to the position between the two tracks. This design, with a limiting strip 41 welded along the length of one side of the handle 4's circumference and a limiting groove 51 formed in the inner wall of the rotating sleeve 5 to slide in conjunction with the limiting strip 41, allows the handle 4 to move horizontally in a straight line under the relative sliding of the limiting strip 41 and the limiting groove 51. This causes the position of the fixed stopper 2 on the double-sided directional light body 1 connected to the handle 4 to change, ensuring that the double-sided directional light body 1 is positioned between the two tracks for effective warning.
[0023] In one embodiment, a mounting groove is provided on the wheel stop 2 at the position corresponding to the rotating sleeve 5, and the rotating sleeve 5 is rotatably connected within the mounting groove. With this design, by creating the mounting groove on the wheel stop 2 at the position corresponding to the rotating sleeve 5, and by rotatably mounting the rotating sleeve 5 within the mounting groove, when the operating handle 4 is rotated, the radial restriction between the limiting strip 41 welded to the handle 4 and the limiting groove 51 synchronously drives the rotating sleeve 5 to rotate, causing the rotating sleeve 5 to rotate within the mounting groove, thereby generating a rotational driving force for the rotating sleeve 5.
[0024] In one embodiment, the belt drive assembly 6 includes a first pulley 61 disposed in the mounting groove and sleeved on the outer wall of the rotating sleeve 5, and a second pulley 62 disposed on the outer wall of the screw 32, wherein a drive belt 63 is disposed on the first pulley 61 and the second pulley 62; Driven by the rotation of the handle 4, the rotating sleeve 5 transmits the rotational force of the rotating sleeve 5 and drives the screw 32 to rotate. This design, with the first pulley 61 mounted on the outer wall of the rotating sleeve 5 and the second pulley 62 mounted on the outer wall of the middle part of the screw 32, allows the screw 32, which passes through the end face of the second pulley 62, to rotate when an external force drives the rotating sleeve 5 to rotate. This transmission of rotational force drives the internally threaded sleeves 34 mounted on both sides of the screw 32 to move apart or towards each other.
[0025] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
