Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine technology, and in particular to a hoisting structure for changing grease in a tunnel boring machine. Background Technology

[0002] A tunnel boring machine (TBM), also known as a shield tunneling machine, integrates optics, mechanics, electronics, hydraulics, sensing, and information technology. It has functions such as excavating and cutting soil and rock, transporting excavated material, assembling tunnel lining, and measuring and guiding. The TBM requires a large amount of grease for lubrication, which needs to be replaced after a certain period of use. Because of the large amount of grease used, a large quantity needs to be transported, necessitating the use of lifting structures for easy handling.

[0003] For example, Chinese patent application CN202420233556.4 discloses a hoisting structure for changing grease in a tunnel boring machine. This structure includes a hoisting plate with connecting plates fixed to both sides of its top. A top plate is fixed between the two connecting plates, and a balancing assembly is provided between the two top plates to improve the stability of the hoisting process. A drive assembly is located at the bottom of the hoisting plate to simultaneously hold two oil drums, improving hoisting efficiency. The drive assembly includes a threaded rod, and movable slots are provided on both the front and rear sides of the bottom of the hoisting plate. This invention uses a motor to drive a holding frame to slide horizontally along the threaded rod, allowing for arbitrary adjustment of the position of the oil drums inside the holding frame. This facilitates grease replacement at any position on the tunnel boring machine, improving hoisting efficiency and usability. Simultaneously, adjusting the position of the two convex sliders sliding along the balancing slots improves hoisting stability and prevents the oil drums from slipping.

[0004] However, the above technical solution still has the following shortcomings in actual use. When adjusting the convex slider, it takes a lot of time to disassemble the bolts, and it cannot be guaranteed that the adjusted convex slider can make the device completely balanced. It takes a lot of time to fine-tune, which is inconvenient to use. Therefore, we propose a hoisting structure for changing grease in tunnel boring machines to solve the above problems. Utility Model Content

[0005] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0006] Specifically, the technical problem to be solved by this utility model is to provide a hoisting structure for changing grease in tunnel boring machines, so as to solve the technical problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A hoisting structure for changing grease in a tunnel boring machine includes a hoisting plate. A mounting base is installed at the top of the hoisting plate, and rotating seats are installed on both sides of the top of the mounting base. Rollers are rotatably connected to each rotating seat. Guide grooves are provided on both the front and rear sides of the bottom of the hoisting plate. Two sets of guide slide plates are installed in each guide groove. A base is installed at the middle of the bottom of each set of guide slide plates. A grease tank frame is rotatably connected to each set of bases. A sleeve is installed at the front end of each set of guide slide plates, and a locking component is provided inside each set of sleeves.

[0009] As an improved technical solution, the locking assembly includes a movable plate slidably connected inside the sleeve and positioning rods fixed at the upper and lower ends of the movable plate. Multiple sets of positioning grooves are equally spaced at both ends of the guide slide plate. A connecting rod is fixed to the middle of the front end of the movable plate, and a pull handle is fixed to the front end of the connecting rod. A return spring is wound around the outside of the connecting rod.

[0010] As an improved technical solution, the guide groove is designed in a "V" shape.

[0011] As an improved technical solution, the outer walls of the two sets of guide slide plates are fully fitted with the inner walls of the guide grooves on the hoisting plate, and the two sets of guide slide plates are slidably connected to the guide grooves.

[0012] As an improved technical solution, the diameter of the two sets of positioning rods on the movable plate is the same as the inner diameter of the positioning groove, and the rear ends of the positioning rods can be inserted into the positioning groove.

[0013] As an improved technical solution, the outer surface of the handle is ground as a whole.

[0014] As an improved technical solution, the two ends of the return spring on the outer wall of the connecting rod are respectively connected to the front end of the outer wall of the movable plate and the front end of the inner wall of the sleeve, and the movable plate is elastically connected to the inner wall of the sleeve through the return spring.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] I. This utility model features a guide groove on the hoisting plate, with two sets of guide slides installed within it. An oil tank can be installed in the oil tank frame at the bottom of the guide slides. A hoisting rope passes through the rollers at the top of the hoisting plate to hoist the entire plate. Under gravity, the two sets of guide slides move to the center of the guide groove, ensuring the hoisting plate's center of gravity is in the middle. This guarantees the stability of the hoisting plate during transport, eliminating the need for extensive balancing adjustments and improving the ease of use of the device.

[0017] II. This utility model has a movable plate that can move back and forth installed inside the sleeve on the guide slide. When the guide slide moves to the desired position, the return spring releases its elastic force to push the movable plate backward, allowing the two sets of positioning rods on the movable plate to insert into the corresponding positioning grooves, thereby quickly fixing the position of the oil tank frame and improving the stability of the device during use.

[0028] Figures 1 to 4 As shown, this embodiment provides a hoisting structure for changing grease in a tunnel boring machine, including a hoisting plate 1, a mounting base 2 installed at the top of the hoisting plate 1, rotating seats 3 installed on both sides of the top of the mounting base 2, and rollers 4 rotatably connected inside the rotating seats 3. Guide grooves 5 are opened on both the front and rear sides of the bottom end of the hoisting plate 1, and two sets of guide slide plates 6 are installed in the guide grooves 5. Bases 7 are installed in the middle of the bottom end of the two sets of guide slide plates 6, and oil tank frames 8 are rotatably connected to the two sets of bases 7. Sleeves 9 are installed at the front end of the two sets of guide slide plates 6, and locking components are provided inside the two sets of sleeves 9.

[0029] By providing a guide groove 5 on the hoisting plate 1 and installing two sets of guide slide plates 6 in the guide groove 5, the oil tank can be installed in the oil tank frame 8 at the bottom of the guide slide plate 6. Then, by passing the hoisting rope through the roller 4 at the top of the hoisting plate 1, the hoisting plate 1 can be hoisted as a whole. The two sets of guide slide plates 6 can move to the middle of the guide groove 5 under the action of gravity, so that the center of gravity of the hoisting plate 1 is located in the middle, thereby ensuring the stability of the hoisting plate 1 during hoisting. There is no need to spend a lot of time on balance adjustment, which improves the convenience of using the device.

[0030] In other embodiments, the locking assembly includes a movable plate 10 slidably connected inside the sleeve 9 and a positioning rod 11 fixed at the upper and lower ends of the movable plate 10. Multiple positioning slots 12 are equally spaced at both the upper and lower ends of the guide slide plate 6. A connecting rod 13 is fixed at the middle of the front end of the movable plate 10. A pull handle 14 is fixed at the front end of the connecting rod 13. A return spring 15 is wound around the outside of the connecting rod 13.

[0031] By installing a movable plate 10 that can move back and forth inside the sleeve 9 on the guide slide plate 6, when the guide slide plate 6 moves to the desired position, the return spring 15 can release its elastic force to push the movable plate 10 to move backward, so that the two sets of positioning rods 11 on the movable plate 10 can be inserted into the positioning grooves 12 at the corresponding positions, thereby quickly fixing the position of the oil tank frame 8 and improving the stability of the device during use.

[0032] like Figure 1 and 2 As shown, the guide groove 5 has a "V" shaped design;

[0033] This design allows the guide slide plate 6 inside the guide chute 5 to move downwards to the middle of the guide chute 5 under the action of gravity, thus ensuring the stability of the hoisting plate 1 during hoisting.

[0034] like Figure 2 As shown, the outer walls of the two sets of guide slide plates 6 are fully fitted with the inner walls of the guide slide grooves 5 on the hoisting plate 1, and the two sets of guide slide plates 6 are slidably connected to the guide slide grooves 5;

[0035] This design ensures that the guide slide plate 6 can slide smoothly inside the eye guide groove 5, thereby reducing the force required to adjust the position of the oil tank frame 8 and improving the ease of use of the device.

[0036] like Figure 4 As shown, the diameter of the two sets of positioning rods 11 on the movable plate 10 is the same as the inner diameter of the positioning groove 12, and the rear ends of the positioning rods 11 can be inserted into the positioning groove 12.

[0037] With this design, when the two sets of positioning rods 11 on the movable plate 10 are inserted into the positioning grooves 12 outside the hoisting plate 1, the positioning rods 11 can be effectively prevented from shaking inside the positioning grooves 12, so that the two sets of positioning rods 11 can form a stable movement limit effect on the guide slide plate 6.

[0038] In other embodiments, the entire outer surface of the handle 14 is polished.

[0039] This design effectively increases the friction between the hand and the handle 14 when it needs to be pulled, thus enabling the handle 14 to be pulled quickly and effectively.

[0040] like Figure 4 As shown, the two ends of the return spring 15 on the outer wall of the connecting rod 13 are respectively connected to the outer wall of the front end of the movable plate 10 and the front end of the inner wall of the sleeve 9. The movable plate 10 forms an elastic connection with the inner wall of the sleeve 9 through the return spring 15.

[0041] This design allows the return spring 15 to continuously release a rearward elastic force on the movable plate 10, enabling the movable plate 10 to drive the two sets of positioning rods 11 to quickly insert into the positioning grooves 12 on the hoisting plate 1.

[0042] This utility model provides a hoisting structure for changing grease in a tunnel boring machine, and its specific working principle is as follows:

[0043] When using this equipment, the oil drum can be placed in the oil tank frame 8 at the bottom of the guide slide plate 6, and then the hoisting rope can be passed through the rollers 4 on the two sets of rotating seats 3 to hoist the entire device. After the hoisting plate 1 moves the oil drum in the oil tank frame 8 to the designated position, the handle 14 can be pulled forward to make the movable plate 10 move the two sets of positioning rods 11 along the inside of the sleeve 9 to the front, so that the two sets of positioning rods 11 completely leave the positioning grooves 12 on the hoisting plate 1, releasing the sliding limit effect on the guide slide plate 6, and allowing the movable plate 10 to squeeze the return spring 15 during the movement. Then, the sleeve 9 can be pushed, so that the guide slide plate 6 moves the oil tank frame 8 and the oil drum along the guide groove 5. By sliding the oil tank, the position can be adjusted quickly and effortlessly by hand, facilitating rapid grease replacement at the required locations on the tunnel boring machine. Releasing the pull on the handle 14 allows the return spring 15 to release its elasticity, pushing the movable plate 10 backward. This allows the two sets of positioning rods 11 on the movable plate 10 to insert into the corresponding positioning slots 12, thus fixing the position of the oil tank frame 8. When further movement is needed, the handle 14 can be pulled forward again. Once the two sets of positioning rods 11 release their restriction on the guide slide plate 6, the guide slide plate 6 can move along the guide groove 5 to its lowest point, allowing the two oil tank frames 8 to be positioned in the middle of the hoisting plate 1, thus quickly maintaining the stability of the hoisting plate 1. The operation is now complete.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
