Description

Technical Field

[0001] This utility model relates to the field of support structure technology, specifically a reinforced frame support structure component. Background Technology

[0002] In the field of underground engineering construction, tunnel boring machines (TBMs), as key excavation equipment, face numerous challenges due to their complex and harsh operating environment. As tunnel excavation projects advance to deeper and longer lengths, extremely high demands are placed on the support stability and ease of maintenance of TBMs.

[0003] Traditional tunneling machine support structures typically employ simple jack-type single-point supports or ordinary rigid supports, which have many drawbacks. When the limiting teeth of the support components are damaged, disassembly and replacement are extremely difficult due to their unreasonable structural design, often requiring a lot of time and causing the tunneling machine to be shut down for extended periods. Therefore, a reinforced frame support structure is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a reinforced frame support structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a reinforced frame support structure, including a support assembly installed at the tail of a tunneling machine, a dust suction assembly on the upper side of the support assembly, a limiting assembly on one side of the dust suction assembly, and a frame body on one side of the support assembly;

[0006] The support assembly includes two bases, one of which is hinged to a support frame and a hydraulic cylinder on one side. The bottom side of the support frame is fixed with a fixing frame that is hinged to the push rod end of the hydraulic cylinder.

[0007] The top side of the fixed frame has several limiting grooves, and a limiting plate is inserted into the inner side of the limiting groove. A connecting rod is inserted into the bottom side of the fixed frame, and a limiting tooth is fixed at the bottom of the connecting rod. A bolt is connected to one side of the limiting plate and one side of the connecting rod.

[0008] Preferably, the above-mentioned dust collection assembly includes a housing, a mounting bracket inserted into the inner wall of the housing, a filter screen fixed inside the mounting bracket, and a horizontal plate fixed to the top of the mounting bracket.

[0009] Preferably, the bottom of the horizontal plate is bonded with a sealing ring, and the bottom of the sealing ring is attached to one side of the top of the box.

[0010] Preferably, the above-mentioned: a fan is installed on the inner wall of the box at the air outlet of the filter screen, the air outlet of the fan is connected to an air outlet pipe, and a number of air inlet pipes located at the air inlet of the filter screen are connected to one side of the box.

[0011] Preferably, the limiting component includes a connecting frame, the inner wall of which has a groove, and a sliding plate is slidably connected to the inner side of the groove.

[0012] Preferably, the slide plate is fixed to one side of a pressure plate that extends through one side of the connecting frame. When the pressure plate is at the top of the horizontal plate, the filter screen is in the installed state. When the pressure plate leaves the top of the horizontal plate, the filter screen is in the disassembled state.

[0013] Preferably, as described above: a spring is connected between one side of the slide plate and the inner side of the slide groove; the top of the base is installed on one side of the bottom of the frame body; the bottom of the box is fixed to one side of the top of the frame body; and the bottom of the connecting frame is fixed to one side of the top of the box.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0015] 1. When the tunneling machine needs support, simply extend the push rod of the hydraulic cylinder to quickly complete the support action. Multiple limit teeth insert into the ground, forming a multi-point support structure, which effectively distributes the weight of the tunneling machine and improves the stability and safety of the support. When the limit teeth are damaged, simply use a tool to remove the bolts and then pull down the limit teeth to easily remove and replace them with new ones. This greatly simplifies the maintenance process, reduces downtime, and improves the operating efficiency of the tunneling machine.

[0016] Second, the suction generated by the fan draws outside air into the inside of the housing through the air intake pipe. Dust is blocked on the air intake side of the filter screen, which effectively filters dust in the air and significantly improves the air quality of the tunneling machine's working environment, providing operators with a healthier and more comfortable working environment.

[0017] Third, the new mounting bracket and filter can be inserted into the inside of the box with a simple insertion action. Then, release the tension of the slide, and the spring force will automatically push the pressure plate to fix the mounting bracket and filter, reducing the time and manpower required for replacement.

[0027] Example

[0028] Please see Figure 1-5 This utility model provides a technical solution: a reinforced frame support structure, including a support component 1 installed at the tail of a tunneling machine, a dust suction component 2 on the upper side of the support component 1, a limiting component 3 on one side of the dust suction component 2, and a frame body 4 on one side of the support component 1.

[0029] The support assembly 1 includes two bases 11. A support frame 12 and a hydraulic cylinder 15 are hinged to one side of each base 11. The bases 11, support frames 12, limiting teeth 13, and fixing frames 14 are all made of metal. Furthermore, the wall thickness of the bases 11, support frames 12, limiting teeth 13, and fixing frames 14 is greater than 10 mm, resulting in higher strength for the support assembly 1. The use of metal materials and ensuring a wall thickness greater than 10 mm significantly improves the overall strength and rigidity of the support assembly 1. A fixing frame, hinged to the push rod end of the hydraulic cylinder 15, is fixed to one side of the bottom of the support frame 12. 14; Several limiting grooves 16 are provided on one side of the top of the fixed frame 14. Limiting plates 17 are inserted into the inner side of the limiting grooves 16. A connecting rod 18 is inserted into one side of the bottom of the fixed frame 14. Limiting teeth 13 are fixed at the bottom of the connecting rod 18. Bolts are connected to one side of the limiting plate 17 and one side of the connecting rod 18. The push rod end of the control hydraulic cylinder 15 extends. At this time, the hydraulic cylinder 15 pushes the support frame 12 to rotate around the hinge point, and at the same time makes the fixed frame 14 contact the ground. At this time, multiple limiting teeth 13 are inserted into the inner side of the ground, increasing the stability between the support assembly 1 and the ground.

[0030] The dust collection assembly 2 includes a housing 21. A mounting bracket 25 is inserted into the inner wall of the housing 21. A filter screen 26 is fixed inside the mounting bracket 25. A horizontal plate 24 is fixed to the top of the mounting bracket 25. A sealing ring is glued to the bottom of the horizontal plate 24. The bottom of the sealing ring is attached to the top side of the housing 21. When the fan 27 is working, it generates suction, which allows outside air to enter the inside of the housing 21 through the air inlet pipe 23. This causes dust to be blocked at the air inlet side of the filter screen 26. The filtered air is discharged through the air outlet pipe 22. The fan 27 is installed on the inner wall of the housing 21 at the air outlet of the filter screen 26. The air outlet of the fan 27 is connected to the air outlet pipe 22. Several air inlet pipes 23 located at the air inlet of the filter screen 26 are connected to one side of the housing 21.

[0031] The limiting component 3 includes a connecting frame 31. A groove 34 is formed on the inner wall of the connecting frame 31. A sliding plate 33 is slidably connected to the inner side of the groove 34. A pressure plate 32, passing through one side of the connecting frame 31, is fixed to one side of the sliding plate 33. When the pressure plate 32 is at the top of the horizontal plate 24, the filter screen 26 is in the installed state. Pulling the sliding plate 33 to one side causes it to move the pressure plate 32 away from the top of the horizontal plate 24, compressing the spring 35 and pulling the horizontal plate 24 upwards. At this point, the filter screen 26 and the mounting frame 25 can be removed from the inside of the housing 21 and can be placed on the top of the housing 21. The dust inside the housing 21 is cleaned by inserting the filter screen 26 into the hole. When the pressure plate 32 leaves the top of the horizontal plate 24, the filter screen 26 is in a disassembled state. A spring 35 is connected between one side of the slide plate 33 and the inner side of the slide groove 34. The top of the base 11 is installed on the bottom side of the frame body 4. The bottom of the housing 21 is fixed to the top side of the frame body 4. The bottom of the connecting bracket 31 is fixed to the top side of the housing 21. Push the pressure plate 32 to the top of the horizontal plate 24 to limit the mounting bracket 25 and the filter screen 26. At this time, the replacement of the filter screen 26 is completed.

[0032] Working principle: When it is necessary to support the tunneling machine, it is only necessary to control the push rod end of the hydraulic cylinder 15 to extend. At this time, the hydraulic cylinder 15 pushes the support frame 12 to rotate around the hinge point, and at the same time makes the fixed frame 14 contact the ground. At this time, multiple limit teeth 13 are inserted into the inside of the ground to increase the stability between the support component 1 and the ground.

[0033] When the limiting tooth 13 is damaged, simply use a tool to remove the bolt, then pull the limiting tooth 13 downwards so that the limiting tooth 13 drives the connecting rod 18 away from the bottom of the fixing frame 14. At this point, the damaged limiting tooth 13 can be removed, and a new limiting tooth 13 can be taken. Insert the connecting rod 18 at the top of the limiting tooth 13 into one side of the bottom of the fixing frame 14, and then use bolts to connect the limiting plate 17 to the connecting rod 18. At this point, the replacement of the limiting tooth 13 can be completed.

[0034] When the tunneling machine is working, the control fan 27 starts to work. When the fan 27 is working, it generates suction, which allows outside air to enter the inside of the housing 21 through the air inlet pipe 23, so that dust is blocked on the air inlet side of the filter screen 26, and the filtered air is discharged through the air outlet pipe 22.

[0035] When a large amount of dust is adsorbed on the surface of the filter screen 26, simply pull the slide plate 33 to one side, so that the slide plate 33 drives the pressure plate 32 away from the top of the horizontal plate 24, so that the slide plate 33 compresses the spring 35 and pulls the horizontal plate 24 upward. At this time, the filter screen 26 and the mounting bracket 25 can be removed from the inside of the box 21, and the residual dust inside the box 21 can be cleaned through the hole opened at the top of the box 21 for inserting the filter screen 26.

[0036] Take the new mounting bracket 25 and filter screen 26 and insert them into the inside of the housing 21. Then release the pulling force of the sliding plate 33. At this time, under the elastic force of the spring 35, the pressure plate 32 is pushed to the top of the horizontal plate 24, limiting the mounting bracket 25 and filter screen 26. At this time, the replacement of filter screen 26 is completed.

[0037] In summary, when the tunneling machine needs support, simply extending the push rod end of the hydraulic cylinder 15 quickly completes the support action. Multiple limiting teeth 13 insert into the ground, forming a multi-point support structure, effectively distributing the weight of the tunneling machine and improving the stability and safety of the support. When the limiting teeth 13 are damaged, simply use a tool to remove the bolts and then pull down the limiting teeth 13 to easily remove and replace them with new ones. This greatly simplifies the maintenance process, reduces downtime, and improves the operating efficiency of the tunneling machine.

[0038] When the fan 27 is working, it generates suction to draw outside air into the inside of the housing 21 through the air intake pipe 23. Dust is blocked on the air intake side of the filter screen 26, which effectively filters dust in the air and significantly improves the air quality of the tunneling machine's working environment, providing operators with a healthier and more comfortable working environment.

[0039] With a simple insertion action, the new mounting bracket 25 and filter screen 26 can be placed inside the housing 21. Then, by releasing the tension of the slide plate 33, the elastic force of the spring 35 will automatically push the pressure plate 32 to fix the mounting bracket 25 and filter screen 26, reducing the time and manpower required for replacement.
