Description

Technical Field

[0001] The present invention relates to the technical field of underground traffic vehicle rescue equipment, and in particular to an urban small-section underground road vehicle rescue device and method. Background Art

[0002] Urban underground road projects are axis-type underground structures. After a traffic accident occurs in the enclosed underground road space, it is extremely easy to cause traffic congestion, and rescue vehicles cannot reach the accident scene in time to transfer the accident vehicle out of the underground road, resulting in increased congestion.

[0003] With the requirements for building beautiful and livable cities and the growth of urban traffic demand, the construction demand for urban underground roads will increase day by day. It is expected that by 2025, a digital acquisition system and a networked transmission system for all elements and the entire life cycle of transportation infrastructure and carrier equipment will be basically formed. By 2035, the transportation infrastructure will be fully digitized in terms of all elements and the entire life cycle, and a sky-earth integrated traffic control network will be basically formed, and on-demand instant travel services will be widely applied.

[0004] Based on this, in the future, there will be smaller urban small passenger car dedicated underground roads with small spaces and low clear heights. For example, the construction of urban underground roads with a building limit of only 6.0m×2.5m for two lanes will become possible. Such small-space underground roads have the advantages of small direct investment, the ability to be combined with other underground facilities for construction, and saving underground space resources, etc., and are feasible in the future.

[0005] In such a low-space underground road space, when a traffic accident occurs, because the height of medium-sized vehicles exceeds the building limit height, this will cause rescue vehicles in the event of a traffic accident to be unable to enter the underground road, resulting in traffic congestion and difficult accident rescue; existing patent inventions for highway tunnel rescue, such as: "A self-propelled new multi-functional tunnel rescue device (CN 111997680)", "A tunnel rescue device and its rescue method (CN104828709)", are all based on large-section and large-space tunnel projects on highways, using the maintenance roads on both sides of the existing tunnel and the top space, and transporting the accident vehicle to the tunnel entrance through a gantry load-bearing truss connected horizontally at the top. Secondly, there are spatial conflicts between the setting of the rescue device and the fans, traffic lights, lighting fixtures, monitoring equipment in the tunnel, and the communication, power cables under the maintenance road, and the reserved tunnel maintenance area, etc. Summary of the Invention

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements, or it can be a "transmission connection", that is, a power connection through various appropriate methods such as belt drive, gear drive or sprocket drive. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] See attached Figure 1-2, this embodiment provides a vehicle rescue device for small-section underground roads in cities, including a moving mechanism 1 and an integrated control processor. The moving mechanism 1 is arranged at the top of the underground road. There are four lifting hydraulic telescopic arms 2 and four auxiliary support hydraulic telescopic arms 3 on the moving mechanism 1. The lifting hydraulic telescopic arms 2 and the auxiliary support hydraulic telescopic arms 3 are arranged in one-to-one correspondence. The lifting hydraulic telescopic arm 2 is hinged to the moving mechanism 1. One end of the auxiliary support hydraulic telescopic arm 3 is hinged to the moving mechanism 1, and the other end is hinged to the lifting hydraulic telescopic arm 2. A forklift tooth 4 is arranged at the end of the lifting hydraulic telescopic arm 2 away from the moving mechanism 1. The integrated control processor is electrically connected to the moving mechanism 1, the lifting hydraulic telescopic arm 2, and the auxiliary support hydraulic telescopic arm 3 respectively.

[0040] The moving mechanism 1 includes two suspension rails 11 and four moving components. Along the lane sidelines, embedded suspension rails 11 are arranged on the top of the corresponding underground road structure. The suspension rails 11 are arranged along the length direction of the underground road. There are two moving components on each suspension rail 11. The moving components are arranged in one-to-one correspondence with the lifting hydraulic telescopic arms 2. The moving components are respectively hinged to the lifting hydraulic telescopic arm 2 and the auxiliary support hydraulic telescopic arm 3. The integrated control processor is electrically connected to the four moving components. Since the positions of the accident vehicles are different and their model sizes are different when an accident occurs, by controlling a set of lifting hydraulic telescopic arms 2 and auxiliary support hydraulic telescopic arms 3 through each moving component, the position of the lifting hydraulic telescopic arm 2 can be flexibly adjusted according to the vehicle situation.

[0041] The moving component includes: a motor, a support, and multiple rollers. The support is rotatably connected to the rollers. The rollers roll along the suspension rail 11. The motor drives the rollers to rotate. The lifting hydraulic telescopic arm 2 and the auxiliary support hydraulic telescopic arm 3 are hinged to the support.

[0042] Both of the two auxiliary support hydraulic telescopic arms 3 on the same suspension rail 11 are arranged between the two lifting hydraulic telescopic arms 2. This setting makes the rescue device structure compact and has a high space utilization efficiency.

[0043] A warning light is arranged on the lifting hydraulic telescopic arm 2. The warning light is arranged on the side of the lifting hydraulic telescopic arm 2 facing away from the auxiliary support hydraulic telescopic arm 3. When the lifting hydraulic telescopic arm 2 is in a vertical state (working state), the warning lights at both ends of the rescue device can play a good warning effect. When the lifting hydraulic telescopic arm 2 is in a horizontal state (non-working state), the warning light faces the top of the underground road and will not affect the normal driving vehicles.

[0044] The forklift tooth 4 is slidably connected to the lifting hydraulic telescopic arm 2, which is convenient for pushing the forklift tooth 4 under the wheels of the accident vehicle. Two forklift teeth 4 are installed on each lifting hydraulic telescopic arm 2. When lifting the accident vehicle, the two forklift teeth 4 are stuck under the wheels, one on the left and one on the right. The forklift tooth 4 is vertically arranged on the lifting hydraulic telescopic arm 2.

[0045] The forklift tooth 4 includes a receiving plate 41, a limiting plate 42 and a connecting plate 43. The two ends of the limiting plate 42 are fixedly connected to the receiving plate 41 and the connecting plate 43 respectively. The limiting plate 42 is arranged parallel to the lifting hydraulic telescopic arm 2. The receiving plate 41 is arranged at one end of the connecting plate 43 away from the auxiliary support hydraulic telescopic arm 3. The connecting plate 43 is slidably connected to the lifting hydraulic telescopic arm 2. When lifting the accident vehicle, the limiting plates 42 of the forklift teeth 4 on both sides of the rescue device play a limiting role on the accident vehicle, preventing the accident vehicle from shaking during the removal process.

[0046] There is a hinge seat 5 between the lifting hydraulic telescopic arm 2 and the auxiliary support hydraulic telescopic arm 3. There is a hinge seat 5 between the auxiliary support hydraulic telescopic arm 3 and the support. The auxiliary support hydraulic telescopic arm 3 is hinged to the hinge seat 5. There is a hinge seat 5 between the lifting hydraulic telescopic arm 2 and the support. The lifting hydraulic telescopic arm 2 is hinged to the hinge seat 5.

[0047] After an accident occurs, the underground road management center issues a rescue instruction according to the accident situation. After the networked terminal receiver in the rescue device receives the rescue instruction, the integrated control processor issues an operation instruction. The lifting hydraulic telescopic arms 2 in the corresponding lanes form a rescue team. According to the position information, the rescue team moves to the accident location driven by the moving mechanism 1. According to the model and size of the accident vehicle, the integrated control processor finely adjusts the position of the lifting hydraulic telescopic arm 2 in the rescue team, and then the intelligent hydraulic assist system 6 extends the lifting hydraulic telescopic arm 2 to the working state (vertical state) through the auxiliary support hydraulic telescopic arm 3. The forklift tooth 4 extends under the wheel, and the lifting hydraulic telescopic arm 2 retracts backward to lift the accident vehicle, and finally it is transported to the underground road exit by the moving mechanism 1, thus completing the rescue work. In the present invention, a set of lifting hydraulic telescopic arm 2 and auxiliary support hydraulic telescopic arm 3 are arranged under each moving component. Through the work of the auxiliary support hydraulic telescopic arm 3, the conversion between the working state and the non-working state of the lifting hydraulic telescopic arm 2 is realized. In the non-working state, the lifting hydraulic telescopic arm 2 shrinks at the top of the underground road and is placed parallel to the road axis, without occupying the building limit and equipment space, reducing the requirement for the installation space; when working, the lifting hydraulic telescopic arm 2 extends to the vertical working state. Secondly, when lifting the vehicle, the structure formed by the auxiliary support hydraulic telescopic arm 3 and the lifting hydraulic telescopic arm 2 is stable and the rescue effect is good; thirdly, the rescue device arranged at the top of the underground road will not have a space conflict with the fans, traffic lights, lighting fixtures, monitoring equipment in the tunnel, the communication and power cables under the maintenance road, and the reserved tunnel maintenance area.

[0048] The present invention also provides a rescue method applying the above-mentioned vehicle rescue device for small-section underground roads in cities, including the following steps:

[0049] The monitoring facilities of the underground road feedback the accident information to the management center and give an alarm;

[0050] The accident management center processes the accident information to obtain rescue information and sends the rescue information to the networked terminal receiver; the rescue information includes the location of the accident vehicle, the model and size of the accident vehicle, etc.

[0051] The networked terminal receiver sends the received rescue information to the integrated control processor, and the integrated control processor controls the movement components to move to the accident vehicle according to the rescue information respectively; during this process, the integrated control processor adjusts the position of the movement components according to information such as the vehicle position, the model and size of the accident vehicle, that is, adjusts the position of the lifting hydraulic telescopic arm 2.

[0052] Start the auxiliary support hydraulic telescopic arm 3 through the intelligent hydraulic assist system 6 and extend its corresponding lifting hydraulic telescopic arm 2 to a vertical state.

[0053] Push the forklift teeth 4 under the wheels, start the lifting hydraulic telescopic arm 2 through the intelligent hydraulic assist system 6, and lift the accident vehicle off the ground.

[0054] The moving mechanism 1 works to transport the accident vehicle to the underground road exit.

[0055] Start the auxiliary support hydraulic telescopic arm 3 through the intelligent hydraulic assist system 6 and contract its corresponding lifting hydraulic telescopic arm 2 to a horizontal state to start preparing for the next rescue.

[0056] Finally, the method of the present invention is only a preferred implementation scheme and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

[0057] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
