Description

Technical Field

[0001] The utility model relates to the technical field related to tunnel transportation, in particular to a tunnel engineering steel structure supporting transportation device. Background Art

[0002] Tunnel engineering is a building built underground or underwater or in a mountain to lay railways or build roads for motor vehicles to pass. According to its location, it can be divided into three categories: mountain tunnel engineering, underwater tunnel engineering and urban tunnel engineering. Mountain tunnel engineering is to pass under mountains or hills to shorten the distance and avoid steep slopes; underwater tunnel engineering is to pass under rivers or straits; urban tunnel engineering is to pass underground in cities to meet the needs of railways passing through large cities. Mountain tunnel engineering is the most built of these 3E types of tunnel engineering.

[0003] In existing tunnel projects, manual driving is mostly used for transportation within a small range and over a short distance. The general steel structure supporting the transportation device includes wheels at the bottom and a vehicle body that supports the steel structure. When the vehicle body collides during transportation, the steel structure on the vehicle body is prone to tipping over, causing the steel structure to fall to the ground. Once the length of the steel structure is greater than the length of the vehicle body, the bearing area of ​​the vehicle body on the steel structure remains unchanged, causing the steel structure to easily tilt to one end during transportation, thereby reducing the transportation efficiency of the steel structure.

The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0027] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0028] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0029] See also Figure 1 to Figure 6 In an embodiment of the utility model, a tunnel engineering steel structure supporting transportation device includes a base 1, a receiving platform 5, a first limit plate 6, a second limit plate 7, a moving part, and a driving connecting rod assembly.

[0030] The details are as follows, including:

[0031] See also Figure 1 , Figure 2 , Figure 3 , a base 1 and a receiving platform 5 fixedly mounted on the base 1, wherein a plurality of first limit plates 6 are symmetrically arranged on the receiving platform 5;

[0032] It also includes a symmetrically arranged moving part, which is installed at the bottom of the receiving platform 5, and a plurality of sets of second limiting plates 7 are arranged on the moving part, and a receiving space for placing the steel structure is formed between two adjacent first limiting plates 6 and the second limiting plates 7;

[0033] The driving connecting rod assembly is symmetrically arranged, with one end hinged to the moving member and the other end hinged to the base 1 , so as to push the moving member to move relative to the receiving platform 5 .

[0034] In detail, in this embodiment, the tunnel engineering steel structure support and transportation device described in the utility model is adopted. When in use, the driving connecting rod assembly is controlled to work, so as to push the movable part to move relative to the receiving platform 5, and the second limit plate 7 moves relative to the first limit plate 6, so that the two adjacent first limit plates 6 and the second limit plates 7 are misaligned, and the bearing area of ​​the accommodating space is changed, thereby realizing the support and transportation of steel structures of different lengths.

[0035] It should be noted that the steel structure is placed between the first limit plate 6 and the second limit plate 7, which plays a role of limiting support for the steel structure, preventing the steel structures from colliding with each other during transportation, and preventing the steel structure from falling from the receiving platform 5.

[0036] Preferably, the base 1 and the receiving platform 5 are fixedly connected via a fixing frame 2, wherein reinforcing ribs are connected between the fixing frame 2 and the receiving platform 5, so that the overall stability of the receiving platform 5 is enhanced.

[0037] See also Figure 2 and Figure 6 The bottom of the receiving platform 5 is fixedly connected with a support plate 3, and the moving part is slidably arranged inside the support plate 3.

[0038] The movable member comprises a movable plate 4 , one end of which is slidably disposed in the support plate 3 , and the second limiting plate 7 is fixedly connected to one end of the movable plate 4 away from the support plate 3 .

[0039] A plurality of strip-shaped sliding grooves 501 slidably matched with the second limiting plate 7 are formed on both sides of the receiving platform 5 .

[0040] To elaborate, when the above-mentioned movable plate 4 is subjected to inclined extrusion, under the limiting action of the support plate 3, the movable plate 4 moves along the length direction of the receiving platform 5, and when the movable plate 4 moves, it drives the second limit plate 7 to move synchronously, and the second limit plate 7 slides relatively in the strip slide groove 501 to avoid interference between the second limit plate 7 and the receiving platform 5 when the movable plate 4 moves, and misalignment occurs between the two first limit plates 6 and the second limit plates 7, so that the accommodating space between the adjacent first limit plates 6 and the second limit plates 7 is changed. According to the length of the steel structure, the bearing area of ​​the receiving platform 5 can be adjusted to avoid transportation difficulties caused by the mismatch between the length of the steel structure and the receiving platform 5, thereby meeting the support and transportation work of steel structures of different lengths.

[0041] See also Figure 3 The driving connecting rod assembly includes a first connecting rod 8 and a second connecting rod 9, one end of the first connecting rod 8 is hinged to the movable plate 4, the second connecting rod 9 is slidably arranged in the first connecting rod 8, one end of the second connecting rod 9 away from the first connecting rod 8 is hinged to the base 1, and the two first connecting rods 8 on the same side are fixedly connected by a connecting plate 10;

[0042] It also includes a telescopic cylinder 11 , one end of which is hinged to the base 1 , and a movable end of which is hinged to the connecting plate 10 .

[0043] Specifically, in one implementation mode, the telescopic cylinder 11 is controlled to work. When the cylinder rod of the telescopic cylinder 11 is extended, an inclined driving force is generated on the first connecting rod 8, so that the first connecting rod 8 moves relative to the second connecting rod 9. The first connecting rod 8 moves along the axial direction of the second connecting rod 9. At the same time, the first connecting rod 8 and the second connecting rod 9 rotate, thereby pushing the movable plate 4 to move relative to the receiving platform 5, so that the first limit plate 6 and the second limit plate 7 are misaligned to adjust the bearing length of the accommodating space to meet the support and transportation work of steel structures of different lengths.

[0044] See also Figure 5 A rotating shaft 13 is disposed at the bottom of the base 1 , wheels 12 are fixedly connected to both ends of the rotating shaft 13 , and a shock absorbing assembly 14 is connected between the rotating shaft 13 and the base 1 .

[0045] The shock absorbing assembly 14 includes a first connecting block 1402 and a second connecting block 1405, wherein the first connecting block 1402 is rotatably connected to the rotating shaft 13 via a hinge frame 1401, and the second connecting block 1405 is fixedly mounted at the bottom of the base 1, and an end of the second connecting block 1405 away from the base 1 is slidably connected to the first connecting block 1402;

[0046] It also includes a piston rod 1404 disposed between the first connection block 1402 and the second connection block 1405 , and a spring 1403 is sleeved on the piston rod 1404 .

[0047] Furthermore, when the tunnel is under construction and there are potholes on the ground, the wheels 12 are easily affected when driving. In order to prevent the base 1 from being shaken, a shock absorbing assembly 14 is provided at the connection between the wheel 12 and the base 1 to reduce the vibration and impact caused by the uneven road surface when the wheel 12 is driving. Among them, the shock absorbing assembly 14 belongs to the prior art and will not be described in detail in this utility model.
