Technical Field
[0001] The present application relates to the technical field of tunnel construction equipment, and in particular to a bracket device. Background Art
[0002] In recent years, with the vigorous development of my country's transportation infrastructure construction, the number and scale of tunnel projects have also shown a trend of continuous growth. In these tunnel projects, hydraulic cylinder push brackets are widely used as a common translation device. Although this method has certain practicality, it also has some potential shortcomings.
[0003] First, the hydraulic cylinder push bracket has high requirements on the flatness and quality of the ground at the construction site in order to withstand the huge reaction force and friction generated during the push; if the ground conditions are not good, the bracket may tilt or deviate in direction, affecting the accuracy and stability of the translation; secondly, the push speed of the hydraulic cylinder is limited. In order to ensure the safety and stability of the translation process, the push speed is usually not too fast, which may limit the translation speed of the shield machine trolley and thus affect the progress of the project; in addition, the use of hydraulic cylinders to push the bracket translation requires more equipment, including hydraulic cylinders, pump stations, thin steel plates, lubricants, etc., which increases the cost and maintenance difficulty of the project, and the operation is also more complicated, and may affect the surrounding environment. Therefore, it is urgent to develop a bracket device with high structural strength, good stability and cost reduction. Utility Model Content
[0004] In order to develop a bracket device with high structural strength, good stability and reduced cost, the present application provides a bracket device.
[0005] The present application provides a bracket device that adopts the following technical solution:
[0006] A bracket device includes a track for introducing a trolley onto the bracket device, and also includes a bracket body, the bracket body includes a bottom frame, a top frame and a plurality of first supports, the plurality of first supports are arranged between the bottom frame and the top frame and connect the bottom frame and the top frame, the first supports are arranged perpendicular to the bottom frame and the top frame; and also includes a plurality of second supports, the second supports are arranged between adjacent first supports and connect the bottom frame and the top frame, the second supports are arranged at an acute angle to the first supports.
[0007] By adopting the above technical scheme, when working, the trolley is guided to the top frame of the bracket body by docking with the trolley through the track, and the trolley is supported by the top frame; the present application utilizes a first support arranged in a direction perpendicular to the base frame and the top frame, and a second support is arranged between adjacent first supports to connect the base frame and the top frame and form an acute angle with the first support, these components are interconnected to form a stable bearing structure, and the arrangement of vertical supports can effectively enhance the stability of the bracket device, prevent twisting and deformation, and can withstand large loads and impact forces, thereby improving the bearing capacity and stability of the bracket device, so that the bracket device of the present application can stably carry the shield machine trolley and move stably; and compared with the existing hydraulic cylinder push bracket, the bracket device of the present application does not need to be used in conjunction with other equipment, thereby saving costs and ensuring safety during movement.
[0008] In a specific possible implementation manner, the second support is arranged at an angle of 30°-60° with the first support.
[0009] By adopting the above technical solution, the connection points between the bottom frame and the top frame can be increased by setting the second support, thereby improving the load-bearing capacity of the entire bracket device, enabling it to withstand a greater weight or load. The second support is set at an angle of 30°-60° to the first support. Within this angle range, a more solid triangular support structure can be formed, thereby enhancing the overall stability of the bracket device and enabling it to better resist the effects of external forces and loads; and it can better balance structural stability and space utilization. The angle within this range can provide sufficient support force without occupying excessive space.
[0010] In a specific possible implementation manner, the arrangement directions of two adjacent second supports are intersecting.
[0011] By adopting the above technical solution, by arranging the two adjacent second supports in a cross-setting manner, support can be provided in multiple directions, making the entire bracket structure more solid and stable, further enhancing the stability and strength of the structure, and at the same time evenly distributing the load, reducing the deflection and deformation of the structure, thereby improving the safety and reliability of the bracket device.
[0012] In a specific possible embodiment, the end of the second support is at least partially in contact with the end of the first support.
[0013] By adopting the above technical solution, a tighter connection is formed between the first support and the second support, making the entire structure more solid and stable, helping to reduce the shaking and movement of the structure and improving the stability of the entire bracket device. The design can also effectively share the load, reduce stress concentration in the structure, and extend its service life.
[0014] In a specific possible implementation manner, it further includes a plurality of third supports, which are arranged along the periphery of the bottom frame and the top frame, and the ends of the bottom frame and the top frame are respectively connected through the corresponding third supports.
[0015] By adopting the above-mentioned technical solution, the third support is arranged along the periphery of the bottom frame and the top frame to form a peripheral support for the entire bracket device. The peripheral setting of the third support can help to evenly distribute the load, reduce local pressure, and reduce stress concentration, thereby improving the bearing capacity of the entire bracket structure, effectively increasing the overall stability and structural strength of the bracket device, and improving the bearing capacity and operational convenience of the entire device.
[0016] In a specific possible implementation manner, a reinforcing rod is provided between the third support and the first support and / or the top frame.
[0017] By adopting the above technical solution, the reinforcing rod is used to provide an additional connection point, and the third support is tightly connected to the first support or the top frame. Such a design can disperse the load, reduce the deformation of the structure, and increase the overall stability.
[0018] In a specific possible implementation manner, the top frame and the bottom frame are rectangular frames, the length of the top frame is greater than the length of the bottom frame, and the width of the top frame is equal to the width of the bottom frame.
[0019] By adopting the above technical solution and utilizing the different sizes and rectangular designs of the top frame and the bottom frame, the entire structure forms an inverted trapezoidal structure. The inverted trapezoidal structure has better stability than a simple parallel structure. The inverted trapezoidal structure can distribute weight more effectively. The longer side of the top frame provides greater stability, while the shorter side of the bottom frame can effectively lower the center of gravity of the structure, reduce the possibility of tilting and shaking, provide better stability and support, and ensure the stability and safety of the bracket device during use; and the larger length of the top frame can provide a larger support area for the trolley, making the stability of the entire structure higher.
[0020] In a specific possible implementation manner, a plurality of reinforcing beams are provided in the top frame and / or the bottom frame, and the reinforcing beams are evenly distributed along the length direction.
[0021] By adopting the above technical solution and setting reinforcing beams inside the top frame and the bottom frame, the bearing capacity of the structure can be improved without increasing the overall size. The deformation of the structure can be reduced by increasing the rigidity and strength of the structure, and the possibility of local stress concentration can be reduced, thereby improving the durability and safety of the structure.
[0022] In a specific possible implementation manner, it also includes a supporting frame, which is detachably connected to the top frame, and the trolley is guided onto the supporting frame through the track.
[0023] By adopting the above technical solution, compared with the original top frame carrying trolley, the detachable support frame allows customization of supporting devices of different types and sizes according to specific needs to accommodate workpieces or loads of different shapes and sizes, and the detachability of the support frame makes installation and maintenance easier.
[0024] In a specific possible implementation manner, it further includes a moving component, wherein the moving component is arranged on the bracket body to enable the bracket body to move.
[0025] By adopting the above technical solution, since the shield machine needs to move forward continuously during the construction process, the movable components on the bracket body are arranged, and the movability of the bracket body allows the bracket device to move with the movement of the shield machine, without the need for additional disassembly and reinstallation, thereby improving construction efficiency.
[0026] In summary, the present application includes at least one of the following beneficial technical effects:
