Description

Technical Field

[0001] The present invention relates to the technical field of emergency avoidance, and particularly to an emergency avoidance device for highway bridges. Background Art

[0002] Highway bridge engineering refers to all the work of planning, designing, constructing, maintaining, and repairing structures that span waters, valleys, and all traffic channels. There are always a large number of vehicles passing on highways and bridges. During the driving process of these vehicles, brake failures often occur. Due to the relatively high speed of the driving vehicles, it is very difficult to control the vehicles. Once the vehicles get out of control, serious traffic accidents will occur. Therefore, it is particularly important to set up corresponding avoidance devices on highways and bridges.

[0003] Most of the existing emergency avoidance devices for highway bridges have poor emergency collision buffering ability when in use, which may lead to the situation that the vehicle is not blocked by the emergency avoidance device and continues to fly out with inertia. Therefore, we propose an emergency avoidance device for highway bridges. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present invention provides an emergency avoidance device for highway bridges to solve the problems raised in the above background art.

[0006] (2) Technical Solutions

A protective frame is provided at the central axis inside the mounting frame. Card slots one are opened at both ends of the top of the mounting frame, and a card slot two is opened at the central axis of the top of the mounting frame. A support mechanism is arranged on the outer surface of the protective frame, and a tensioning mechanism is fixedly connected to the top of the mounting frame.

[0008] Preferably, the support mechanism includes a connecting block fixedly connected to the inner wall of the mounting frame. A support frame is arranged on the top of the connecting block. A fixing block is fixedly connected to the inner wall of the support frame and penetrates through the protective frame.

[0009] Preferably, the right end of the support frame is located inside the card slot two, and the outer surface of the support frame is in contact with the inner wall of the card slot two. The inside of the support frame is in contact with the outer surface of the protective frame.

[0010] Preferably, a chute is opened on the surface of the fixing block, and a slot one is opened at the central axis of the fixing block, and the chute is communicated with the slot one. A limiting block is arranged inside the chute, and the outer surface of the limiting block is in contact with the inner wall of the chute.

[0011] Preferably, a pull rod is fixedly connected to the outer surface of the limit block, and one end of the pull rod away from the limit block is located inside the first slot, and the pull rod slightly extends out of the first slot.

[0012] Preferably, the tensioning mechanism includes a fixed rod fixedly connected to the inner wall of the first card slot, and the right end of the fixed rod is inclined upward. A card sleeve is sleeved on the outer surface of the fixed rod, and a connecting sleeve is sleeved on the outer surface of the card sleeve.

[0013] Preferably, a second slot is formed on the surface of the card sleeve, and the inner part of the connecting sleeve is in contact with the outer surface of the card sleeve. A pull rope is fixedly connected to the outer surface of the connecting sleeve, and one end of the pull rope away from the connecting sleeve is fixedly connected to the surface of the protective frame.

[0014] Preferably, the tensioning mechanism further includes a limit frame fixedly connected to the top of the mounting frame. A third slot is formed on the surface of the limit frame, and the outer surface of the fixed rod is fixedly connected to the inner wall of the third slot.

[0015] Compared with the prior art, the present invention provides an emergency refuge device for highway bridges, which has the following beneficial effects:

[0016] 1. In the present invention, the vehicle enters the inside of the mounting frame along the mounting frame, decelerates after rubbing against the sand and gravel filled inside the mounting frame. When the vehicle is inside the mounting frame, it slides along the protective frame by inertia until the vehicle is caught by the protective frame, so that the vehicle and personnel can be well protected.

[0017] 2. In the present invention, the protective frame is supported by setting a connecting block and a support frame in cooperation, and by arranging a fixed block inside the support frame, the fixed block can be restricted by the limit block in the sliding slot opened in its own interior, so as to assist the support frame to limit the opening angle of the protective frame and avoid the possibility that the vehicle flies out of the mounting frame along the protective frame.

[0018] 3. In the present invention, by connecting pull ropes at both ends of the protective frame, after the protective frame is impacted, the upper end of the protective frame opens and pulls the connecting sleeve through the pull ropes, so that the connecting sleeve slides along the surface of the card sleeve and squeezes the card sleeve. After the protective frame stops being stressed, the connecting sleeve can reset under the elastic force of the card sleeve, which is convenient for subsequent reuse.

[0019] 4. In the present invention, by arranging a limit frame on the outer surface of the fixed rod and opening a third slot on the surface of the limit frame, the upward movement of the fixed rod can be well restricted, so that the fixed rod can well restrict the protective frame through the pull ropes. At the same time, the fixed rod can also be pressed down, and the card sleeve and the connecting sleeve are slid down along the fixed rod to replace the pull ropes or the card sleeve, ensuring the safety protection effect of the device.

[0030] Please refer to Figure 1-6, the present invention provides a technical solution: an emergency refuge device for highway bridges, including a mounting frame 1. At the central axis inside the mounting frame 1, a protective frame 2 is provided. At both ends of the top of the mounting frame 1, a first card slot 3 is opened. At the central axis of the top of the mounting frame 1, a second card slot 4 is opened. A support mechanism 5 is arranged on the outer surface of the protective frame 2. A tensioning mechanism 6 is fixedly connected to the top of the mounting frame 1. By allowing the vehicle to enter its interior along the mounting frame 1 and decelerate after friction with the sand and gravel filled inside the mounting frame 1, when the vehicle is inside the mounting frame 1, it slides along the protective frame 2 by inertia until the vehicle is stuck by the protective frame 2, so that the vehicle and personnel can be well protected.

[0031] The support mechanism 5 includes a connection block 51, and the connection block 51 is fixedly connected to the inner wall of the mounting frame 1. At the top of the connection block 51, a support frame 52 is provided. The right end of the support frame 52 is located inside the second card slot 4, and the outer surface of the support frame 52 is in contact with the inner wall of the second card slot 4. The inner part of the support frame 52 is in contact with the outer surface of the protective frame 2. A fixing block 54 is fixedly connected to the inner wall of the support frame 52. The fixing block 54 penetrates the protective frame 2. A chute 55 is opened on the surface of the fixing block 54. A first slot 57 is opened at the central axis of the fixing block 54, and the chute 55 is communicated with the first slot 57. A limiting block 56 is arranged inside the chute 55, and the outer surface of the limiting block 56 is in contact with the groove wall of the chute 55. A pull rod 58 is fixedly connected to the outer surface of the limiting block 56, and the end of the pull rod 58 away from the limiting block 56 is located inside the first slot 57 and slightly extends out of the first slot 57. By arranging the connection block 51 and the support frame 52 to cooperate to support the protective frame 2, and by arranging the fixing block 54 inside the support frame 52, the fixing block 54 can be restricted by the limiting block 56 inside the chute 55 opened in its own interior, which can assist the support frame 52 to limit the opening angle of the protective frame 2 and avoid the possibility that the vehicle flies out of the mounting frame 1 along the protective frame 2.

[0032] The tensioning mechanism 6 includes a fixed rod 61. The fixed rod 61 is fixedly connected to the inner wall of the first slot 3. The right end of the fixed rod 61 is inclined upward. A bushing 62 is sleeved on the outer surface of the fixed rod 61. A second slot 621 is formed on the surface of the bushing 62. The inner part of the connecting sleeve 63 is in contact with the outer surface of the bushing 62. A pull rope 64 is fixedly connected to the outer surface of the connecting sleeve 63. By connecting the pull ropes 64 at both ends of the protective frame 2, after the protective frame 2 is impacted, the upper end of the protective frame 2 opens and pulls the connecting sleeve 63 through the pull rope 64, so that the connecting sleeve 63 slides along the surface of the bushing 62 and squeezes the bushing 62. After the protective frame 2 stops being stressed, the connecting sleeve 63 can reset under the elastic force of the bushing 62, which is convenient for subsequent reuse. One end of the pull rope 64 away from the connecting sleeve 63 is fixedly connected to the surface of the protective frame 2. The connecting sleeve 63 is sleeved on the outer surface of the bushing 62. The tensioning mechanism 6 further includes a limiting frame 65. The limiting frame 65 is fixedly connected to the top of the mounting frame 1. A third slot 651 is formed on the surface of the limiting frame 65. The outer surface of the fixed rod 61 is fixedly connected to the inner wall of the third slot 651. By arranging the limiting frame 65 on the outer surface of the fixed rod 61 and forming the third slot 651 on the surface of the limiting frame 65, the upward movement of the fixed rod 61 can be well restricted, so that the fixed rod 61 can well restrict the protective frame 2 through the pull rope 64. At the same time, the fixed rod 61 can also be pressed down, and the bushing 62 and the connecting sleeve 63 are slid down along the fixed rod 61 to replace the pull rope 64 or the bushing 62, ensuring the safety protection effect of the device.

[0033] During use, the vehicle enters the inside of the mounting frame 1 along it, decelerates after friction with the sand and gravel filled inside the mounting frame 1, and the vehicle slides along the protective frame 2 by inertia when it is inside the mounting frame 1 until the vehicle is caught by the protective frame 2, so that the vehicle and personnel can be well protected.

[0034] By arranging the connecting block 51 and the support frame 52 to cooperate to support the protective frame 2, and by arranging the fixed block 54 inside the support frame 52, the fixed block 54 can be restricted by the limiting block 56 inside the sliding slot 55 formed in its own interior, which can assist the support frame 52 to limit the opening angle of the protective frame 2 and avoid the possibility that the vehicle flies out of the mounting frame 1 along the protective frame 2.

[0035] Furthermore, by connecting the pull ropes 64 at both ends of the protective frame 2, after the protective frame 2 is impacted, the upper end of the protective frame 2 opens and pulls the connecting sleeve 63 through the pull rope 64, so that the connecting sleeve 63 slides along the surface of the bushing 62 and squeezes the bushing 62. After the protective frame 2 stops being stressed, the connecting sleeve 63 can reset under the elastic force of the bushing 62, which is convenient for subsequent reuse.

[0036] By providing a limiting frame 65 on the outer surface of the fixed rod 61 and opening a third slot 651 on the surface of the limiting frame 65, the upward movement of the fixed rod 61 can be well restricted, enabling the fixed rod 61 to well restrict the protective frame 2 through the pull rope 64. At the same time, the fixed rod 61 can also be pressed down, and after the bushing 62 and the connecting sleeve 63 slide down along the fixed rod 61, the pull rope 64 or the bushing 62 can be replaced to ensure the safety protection effect of the device.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
