Description
Technical Field
[0001] The utility model belongs to the technical field of track construction, and in particular relates to a warning device for subway track construction management. Background Art
[0002] Subway track construction is a complex and dangerous task. To ensure the safety of the construction and the surrounding environment, a series of effective warning measures must be taken. Moreover, most subway track construction is carried out underground. Compared with the warning devices used on the ground, the warning devices used in subway track construction need to have a more obvious warning effect.
[0003] Currently, most warning devices used in tracks only have warning lights compared to ground warning devices. However, during the track construction process, if common warning devices on the market are placed directly on the track, the contact area between the device and the track is small, which will affect the stability of the warning device. The wind or shaking generated during the track construction may cause the warning device to fall.
[0004] For this reason, we propose a warning device for subway track construction management to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to solve the problems in the prior art and to propose a warning device for subway track construction management.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A warning device for subway track construction management includes a warning sign, a front frame and a rear frame, the warning sign is fixedly arranged on the side wall of the front frame, the rear frame is rotatably connected to the side wall of the front frame, the side wall of the front frame and the side wall of the rear frame are both fixedly provided with a cross bar, a rotating ring is rotatably connected to the cross bar, the side wall of the rotating ring is fixedly connected to a support rod, a fixed seat is arranged on one end of the support rod away from the rotating ring, a bottom plate is fixedly connected to the bottom of the fixed seat, two clamping plates are arranged at the bottom of the bottom plate, a cavity is opened in the bottom plate, and a driving mechanism for controlling the clamping plates is arranged in the cavity.
[0008] Preferably, a through hole is provided on the side wall of the fixing seat, a cylindrical pin is installed in the through hole, and the cylindrical pin also passes through the side wall of the support rod, and a cotter pin is installed on one end of the cylindrical pin through the fixing seat.
[0009] Preferably, the driving mechanism includes a positive and negative screw rod, a rotating block, two moving rings and two connecting rods. The rotating block is rotatably connected to the side wall of the cavity, one end of the positive and negative screw rod is fixedly connected to the side wall of the rotating block, and the other end is rotatably connected to the side wall of the cavity away from the rotating block. The two moving rings are respectively threadedly connected to the two opposite threaded sections of the positive and negative screw rods, and the two connecting rods are respectively fixedly connected to the bottom of the two moving rings. A moving groove is provided on the bottom wall of the cavity, and the two connecting rods are respectively slidably connected to the inner wall of the moving groove, and the end of the connecting rod away from the moving ring is fixedly connected to the top wall of the splint.
[0010] Preferably, the rotating block passes through the side wall of the cavity at one end away from the positive and negative screw rods, and a slot is provided on the side wall of the rotating block at one side away from the positive and negative screw rods.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0021] like Figure 1 - Figure 4 As shown, a warning device for subway track construction management includes a warning sign 1, a front frame 2 and a rear frame 3. The warning sign 1 is fixedly arranged on the side wall of the front frame 2. The side wall of the warning sign 1 is also provided with a number of LED bulbs to ensure brightness during underground construction. The rear frame 3 is rotatably connected to the side wall of the front frame 2. The side walls of the front frame 2 and the rear frame 3 are both fixedly provided with a cross bar 4. A rotating ring 5 is rotatably connected to the cross bar 4. The rotating ring 5 is arranged in the middle position of the cross bar 4. The diameter of the rotating ring 5 is larger than the outer diameter of the cross bar 4. A support rod 6 is fixedly connected to the side wall of the rotating ring 5. The end of the support rod 6 away from the rotating ring 5 is designed as an arc. The width of the support rod 6 is smaller than the width of the rotating ring 5. The rotating ring 5 can rotate around the cross bar 4. After the front frame 2 and the rear frame 3 are brought together, the rotating ring 5 can drive the support rod 6 to fold together, which is convenient for the staff to carry the warning sign 1.
[0022] A fixing seat 7 is installed at one end of the support rod 6 away from the rotating ring 5, and a through hole 10 is opened on the side wall of the fixing seat 7. A cylindrical pin 11 is installed in the through hole 10. The cylindrical pin 11 also passes through the side wall of the support rod 6. The cylindrical pin 11 passes through one end of the fixing seat 7 and is installed with a cotter pin 12. When the warning sign 1 is not used, the cotter pin 12 can be removed from the cylindrical pin 11, and then the cylindrical pin 11 can be removed, so that the fixing seat 7 is separated from the support rod 6, which is convenient for the staff to fold up the front frame 2 and the rear frame 3.
[0023] The bottom of the fixed seat 7 is fixedly connected to a base plate 8, and two splints 9 are arranged at the bottom of the base plate 8. A cavity is opened in the base plate 8, and a driving mechanism for controlling the splint 9 is installed in the cavity. The driving mechanism includes positive and negative screw rods 13, a rotating block 14, two moving rings 15 and two connecting rods 16. The rotating block 14 is rotatably connected to the side wall of the cavity, and the rotating block 14 passes through the side wall of the cavity away from the end of the positive and negative screw rods 13. A slot 18 is opened on the side wall of the rotating block 14 away from the side of the positive and negative screw rods 13. The shape of the slot 18 can be set by yourself, and the staff needs to prepare a rotating device that is consistent with the shape of the slot 18.
[0024] One end of the positive and negative screw rods 13 is fixedly connected to the side wall of the rotating block 14, and the other end is rotatably connected to the side wall of the cavity away from the rotating block 14. The two moving rings 15 are respectively threadedly connected to the two opposite threaded sections of the positive and negative screw rods 13, and the two connecting rods 16 are respectively fixedly connected to the bottom of the two moving rings 15. A moving groove 17 is provided on the bottom wall of the cavity, and the two connecting rods 16 are respectively slidably connected to the inner walls of the moving groove 17. The end of the connecting rod 16 away from the moving ring 15 is fixedly connected to the top wall of the splint 9.
[0025] The working principle is as follows: the staff will first use the rotating equipment that matches the slot 18 to drive the rotating block 14, so that the forward and reverse screw rods 13 rotate, and the two moving rings 15 installed on the forward and reverse screw rods 13 will move relative to each other, thereby driving the connecting rod 16 and the splint 9 at the bottom of the moving ring 15 to move together, clamping heavy objects such as sleepers on the track, which will ensure that the warning sign 1 is placed more stably at the construction site.
[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
