Description

Technical Field

[0001] This utility model relates to the technical field of sign structure, and in particular to a parking signal sign. Background Technology

[0002] With the continuous improvement of national infrastructure, the continuous increase in railway transport capacity, and the leapfrog development of the social economy, it is necessary to upgrade and renovate the existing equipment and facilities of railway operating lines. Among these methods, temporarily closing the operating line is a maintenance or construction method that minimizes the impact on the railway and allows for the completion of upgrades such as repairs or replacements of local lines or switches.

[0003] To ensure that self-propelled equipment does not enter the construction area during railway line closure construction, especially to avoid collisions with personnel and equipment undergoing closure construction, and to ensure traffic safety, construction units are required to set up mobile railway stop signs within the safety clearance of the railway line in accordance with current railway regulations. This serves as a warning that there is construction work ahead of the self-propelled equipment, prompting it to slow down and stop.

[0004] Most existing parking signs are simple devices made by welding poles, iron plates, and nuts together. During installation, safety personnel manually screw the movable parking sign with nuts onto the fastener bolts on the outside of the rail, which is a cumbersome operation. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of existing technologies, such as the need to set up temporary stop signs within the safety clearance of railway operating lines during railway closure construction, where the existing stop signs need to be fixed to fastener bolts on the outside of the track, and the installation and removal process is relatively cumbersome. This invention provides a new type of stop sign.

[0006] In a first aspect, the present invention provides a stop signal sign, comprising:

[0007] Base unit;

[0008] A rotating unit is rotatably connected to the base unit. One side of the rotating unit is provided with a stop mark. The rotating unit has a first position and a second position. When the rotating unit is in the first position, the plane in which the rotating unit is located is parallel to the plane in which the base unit is located. When the rotating unit is in the second position, the angle between the plane in which the rotating unit is located and the plane in which the base unit is located is greater than 0.

[0009] A fixing unit is disposed on the bottom surface of the base unit, and the fixing unit is used to engage the rail.

[0010] The rotating unit is rotatably connected to the base unit and can adjust its angle with the base unit according to the environment. When the device is in operation, the rotating unit is in the second position; when the device is not in operation, the rotating unit is in the first position, thus facilitating the transportation and movement of the signal sign. The fixing unit is connected to the bottom surface of the rotating unit and is used to snap onto the rail. Compared with the existing technology that requires fastener bolts to fix the stop signal sign to the outside of the rail, this device directly fixes it by snapping onto the rail, which is simple to operate and improves construction efficiency. Moreover, the fixing unit can minimize the risk of the base unit tipping over due to the position of the rotating unit.

[0011] Preferably, it further includes a first telescopic rod, one end of which is hinged to the rotating unit and the other end of which is hinged to the base unit.

[0012] A first telescopic rod is provided, with its two ends hinged to the rotating unit and the base unit, respectively. When the first telescopic rod extends or shortens to adjust the angle between the plane where the rotating unit is located and the plane where the base unit is located, the connection between the first telescopic rod and the rotating unit and the base unit is not affected.

[0013] Preferably, the first telescopic rod is a hydraulic rod, a pneumatic rod, or an electric push rod.

[0014] Preferably, the base unit is provided with a first sliding track and a sliding block inside. The length direction of the first sliding track is perpendicular to the length direction of the rotation axis of the rotating unit. The sliding block can move along the length direction of the first sliding track. The first telescopic rod is hinged to the base unit through the sliding block.

[0015] The length direction of the first sliding track is perpendicular to the rotation axis of the rotating unit. The sliding block can move along the first sliding track, and by adjusting the position of the sliding block on the first sliding track, it can adapt to different angles between the plane where the rotating unit is located and the plane where the base unit is located.

[0016] Preferably, the base unit is further provided with a telescopic device, which can adjust the distance between the rotating unit and the fixed unit.

[0017] The telescopic device adjusts the distance between the rotating unit and the fixed unit, thereby adjusting the height of the device to suit different working environments.

[0018] Preferably, the telescopic device includes a scissor lift frame and a second sliding rail. The length direction of the second sliding rail is perpendicular to the length direction of the rotation axis of the rotating unit. The scissor lift frame includes fixed legs and movable legs. The movable legs are connected to the second sliding rail via casters, which are capable of moving along the length direction of the second sliding rail.

[0019] The casters move along the length of the second sliding track, thereby adjusting the distance between the casters and the fixed outriggers, and thus adjusting the height of the scissor lift itself.

[0020] Preferably, the scissor lift includes at least two connecting rods, with both ends of the connecting rods connected to the two scissor arms on both sides of the scissor lift, wherein the two connecting rods are connected by a second telescopic rod, and both ends of the second telescopic rod are hinged to the connecting rods.

[0021] Preferably, the fixing unit is a telescopic rail clamp.

[0022] The fixing unit is a telescopic rail clamp, which is easy to install.

[0023] Preferably, the extension direction of the telescopic rail clamp is parallel to the length direction of the rotating unit's axis of rotation.

[0024] If the extension direction of the telescopic rail clamp is parallel to the length direction of the rotating shaft, then in the working state, the extension direction of the telescopic rail clamp is towards the rails on both sides of the device.

[0025] Preferably, it further includes a PLC controller, which is signal-connected to the rotating unit and is used to control the angle between the plane where the rotating unit is located and the plane where the base unit is located.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] This utility model provides a stop signal sign, including a base unit, a rotating unit, and a fixing unit. The rotating unit and the base unit are rotatably connected, and the fixing unit is disposed on the bottom surface of the base unit and is used to engage with the rail. The rotating unit is rotatably connected to the base unit and can adjust its angle with the base unit according to the environment. When the device is in working condition, the rotating unit is in a second position; when the device is not in working condition, the rotating unit is in a first position, thereby facilitating the transportation and movement of the signal sign. The fixing unit is connected to the bottom surface of the rotating unit and is used to engage with the rail. Compared with the prior art, which requires fastener bolts to fix the stop signal sign to the outside of the rail, this device directly engages with the rail for fixation, which is simple to operate and improves construction efficiency. Moreover, the fixing unit can minimize the risk of the base unit overturning due to the position of the rotating unit. This application overcomes the shortcomings of the prior art, which requires temporary stop signal signs to be set up within the safety limit of the railway operating line during railway closure construction, but the existing stop signal signs require fastener bolts to be fixed to the outside of the rail, making the installation and removal process cumbersome.

[0037] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0038] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use.

[0043] Example 1

[0044] like Figures 1 to 7 As shown, a stop signal sign includes:

[0045] Base unit 1;

[0046] A rotating unit 2 is rotatably connected to the base unit 1. One side of the rotating unit 2 is provided with a stop mark. The rotating unit 2 has a first position and a second position. When the rotating unit 2 is in the first position, the plane in which the rotating unit 2 is located is parallel to the plane in which the base unit 1 is located. When the rotating unit 2 is in the second position, the angle between the plane in which the rotating unit 2 is located and the plane in which the base unit 1 is located is greater than 0.

[0047] A fixing unit is disposed on the bottom surface of the base unit 1, and the fixing unit is used to engage the rail.

[0048] Rotating unit 2 is rotatably connected to base unit 1. It can adjust its angle with base unit 1 according to the environment. When the device is in operation, rotating unit 2 is in the second position; when the device is not in operation, rotating unit 2 is in the first position, facilitating the transportation and movement of the signal sign. A fixing unit is connected to the bottom surface of rotating unit 2 and is used to snap onto the rail. Compared to existing technologies that require fasteners and bolts to fix the stop signal sign to the outside of the rail, this device directly fixes it by snapping onto the rail, simplifying operation and improving construction efficiency. Furthermore, the fixing unit helps to minimize the risk of base unit 1 tipping over due to the position of rotating unit 2.

[0049] Furthermore, it also includes a PLC controller ( Figures 1-7 (All figures are shown in the image). The PLC controller is signal-connected to the rotating unit 2, and the PLC controller is used to control the angle between the plane where the rotating unit 2 is located and the plane where the base unit 1 is located. In this embodiment, the PLC controller can periodically adjust the rotating unit 2 to a first position and a second position. This is to minimize the impact on train operation caused by the safety personnel forgetting to retrieve the stop signal sign.

[0050] In optional implementations, such as Figure 1 and Figure 3As shown, it also includes a first telescopic rod 4, one end of which is hinged to the rotating unit 2, and the other end of which is hinged to the base unit 1. With the first telescopic rod 4 hinged to both ends of the rotating unit 2 and the base unit 1 respectively, when the first telescopic rod 4 extends or shortens to adjust the angle between the plane containing the rotating unit 2 and the plane containing the base unit 1, the connections between the first telescopic rod 4 and the rotating unit 2 and the base unit 1 remain unaffected.

[0051] Furthermore, the first telescopic rod 4 is a hydraulic rod, a pneumatic rod, or an electric push rod.

[0052] Furthermore, such as Figure 1 and Figure 3 As shown, the base unit 1 is internally provided with a first sliding track 5 and a sliding block 6. The length direction of the first sliding track 5 is perpendicular to the length direction of the rotation axis of the rotating unit 2. The sliding block 6 can move along the length direction of the first sliding track 5. The first telescopic rod 4 is hinged to the base unit 1 through the sliding block 6. Since the length direction of the first sliding track 5 is perpendicular to the rotation axis of the rotating unit 2, and the sliding block 6 can move along the first sliding track 5, the position of the sliding block 6 can be adjusted to adapt to different angles between the plane where the rotating unit 2 is located and the plane where the base unit 1 is located.

[0053] In optional implementations, such as Figure 3 As shown, the base unit 1 is also provided with a telescopic device, which can adjust the distance between the rotating unit 2 and the fixed unit.

[0054] Furthermore, such as Figure 3 As shown, the telescopic device includes a scissor lift frame and a second sliding rail 8. The length direction of the second sliding rail 8 is perpendicular to the length direction of the rotation axis of the rotating unit 2, and the second sliding rail 8 is located in the lower region of the base unit 1. The scissor lift frame includes a fixed support leg 701 and a movable support leg 702. The fixed support leg 701 is hinged to the lower region of the base unit 1. The movable support leg 702 is connected to the second sliding rail 8 via casters 703, which can move along the length direction of the second sliding rail 8. Additionally, the upper end of the movable support leg 702 is hinged to the upper region of the base unit 1, and the upper end of the fixed support leg 701 is slidably connected to the bottom surface of the first sliding rail 5 via casters 702. In actual use, the base unit 1 is raised or lowered by moving the two sets of casters 702 along the first sliding rail 5 and the second sliding rail 8 respectively.

[0055] Furthermore, such as Figure 3As shown, the scissor lift includes at least two connecting rods 704, with both ends of the connecting rods 704 connected to the two scissor arms on both sides of the scissor lift. The two connecting rods 704 are connected by a second telescopic rod 9, with both ends of the second telescopic rod 9 hinged to the connecting rods 704.

[0056] Furthermore, such as Figures 1 to 7 As shown, the fixing unit is a telescopic rail clamp 3. The extension direction of the telescopic rail clamp 3 is parallel to the length direction of the rotation axis of the rotating unit 2. The end of the telescopic rail clamp 3 is provided with an upper protrusion for engaging the rail.

[0057] In optional implementations, such as Figure 4 and Figure 5 As shown, the rotating unit 2 is connected to the base unit 1 via the bearing 201.

[0058] In optional implementations, such as Figure 6 and Figure 7 As shown, it also includes a mainspring 10, and the angle between the plane where the rotating unit 2 is located and the plane where the base unit 1 is located is adjusted by the mainspring 10.

[0059] The above content is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
