[0001] The invention belongs to the field of transportation equipment, and in particular relates to intelligent transportation equipment for tunnel construction. Background Art

[0002] Urban vertical tunnel construction usually adopts several main methods such as open cut method, caisson method, shield method, etc. The open cut method is suitable for situations where ground conditions permit and the tunnel depth is shallow, and the tunnel is built by directly excavating the ground.

The middle roller 13 is located at the corner of the conveyor belt, abutting against the inner upper wall of the conveyor belt. Reference Figure 8 The limiting wheels 12 are located on both sides of the conveyor belt, abutting against the outer lower wall surface at the corner of the conveyor belt. Two limiting wheels 12 are provided, and two connecting frames 11 are provided accordingly. The two limiting wheels 12 are formed to limit and support at the corner of the conveyor belt. The two limiting wheels 12 are spaced apart to form a space for the slag plate 3 to pass through, avoiding interference. The two ends of the upper roller shaft 4 are rotatably connected to the fixed frame 5, and the bottom of the fixed frame 5 is fixedly connected to the slide seat 7, and a space for the slag plate 3 to pass through is formed between the two fixed frames 5. The two ends of the lower roller shaft 14 are respectively connected to connecting rods 18, and a space for the slag plate 3 to pass through is formed between the two connecting rods 18.

[0035] In the present invention, the end of the upper roller 4 is connected to the output end of the motor, and the motor can be installed on the fixed frame 5 or the slide 7, and the output end of the motor can be directly connected to the end of the upper roller 4, or connected through a belt. The conveyor belt is preferably a synchronous belt, and the upper roller 4, the middle roller 13 and the lower roller 14 are corresponding synchronous rollers.

[0036] When the present invention is implemented, the upper section 1 is placed on the ground, the upper fixing plate 8 is fixed to the ground by anchor bolts, the lower section 2 is placed in the tunnel 9, and the lower fixing plate 16 is fixed to the ground of the tunnel 9 by anchor bolts; the lower section 2 forms a vertical conveying direction, the slag is conveyed upward by the slag plate 3, and the slag is conveyed horizontally by the upper section 1, and finally the slag is dumped at the end of the upper section 1 to complete the automatic conveying of the slag; the length of the upper section 1 and the lower section 2 can be adjusted by the sliding slide 7 to adapt to tunnels 9 of different depths and the ground of different unloading positions, and the inclination angle of the lower section 2 can be adjusted by the connecting rod 18 to make the lower section 2 inclined or vertically set to form different conveying angles to adapt to different tunnel 9 widths and slag construction recovery locations in the tunnel 9.

[0037] In addition, a guide plate 6 can be fixedly connected to the top of the slide seat 7. The guide plate 6 is located directly below the upper roller shaft 4 and is used to guide the slag to be discharged.

[0038] Furthermore, two of the connecting rod 18 and the vertical rod 15 are provided, and the two connecting rods 18 are distributed at both ends of the lower roller shaft 14. The ends of the two connecting rods 18 away from the lower roller shaft 14 are rotatably connected to the sliding sleeves 17 respectively, and the two sliding sleeves 17 are slidably mounted on the two vertical rods 15 up and down. An intermediate rod 38 is provided between the two vertical rods 15, and an adjusting sleeve 39 is mounted on the intermediate rod 38. The two sides of the adjusting sleeve 39 are fixedly connected to the two sliding sleeves 17 by connecting rods 40; the top and bottom of the intermediate rod 38 are rotatably connected to the upper fixed plate 8 and the lower fixed plate 16 respectively, and the adjusting sleeve 39 is connected to the intermediate rod 38 in an adjustable height.

[0039] like Figure 7 , the vertical rod 15 and the middle rod 38 are fixed parts in the structure, and the adjustment sleeve 39 and the sliding sleeve 17 are parts that can slide up and down. When the adjustment sleeve 39 is raised or lowered, the sliding sleeve 17 is raised or lowered through the connecting rod 40. The sliding sleeve 17 then tilts the connecting rod 18, thereby pushing the lower roller shaft 14 to move, which plays the role of adjusting the tilt angle of the lower section 2. The adjustment sleeve 39 can be locked on the middle rod 38 by abutting the middle rod 38 with a bolt on the side, thereby achieving the function of adjusting the height. The locking of the position on the middle rod 38 can also be achieved through a buckle or ratchet mechanism.

[0040] Furthermore, it also includes a box 19 and a slide plate 21; the box 19 is arranged on the inner side of the lower section 2, the top of the box 19 is connected to the middle roller 13, the top of the slide plate 21 is arranged in the box 19 to slide up and down, the bottom of the slide plate 21 passes through the box 19, and the bottom of the slide plate 21 is connected to the lower roller 14;

[0041] The slide plate 21 is connected to the box body 19 in an adjustable height.

[0042] By adjusting the height of the slide plate 21, the height of the lower roller 14 can be adjusted, and the height of the adjusting sleeve 39 and the sliding sleeve 17 changes accordingly, and the sliding seat 7 is moved to achieve the function of adjusting the length of the upper section 1 and the lower section 2.

[0043] like Figure 1-Figure 3 The slide plate 21 is fixedly connected to a second limiting protruding tooth 24, and a plurality of the second limiting protruding teeth 24 are arranged side by side in the vertical direction, and a second tooth groove is formed between two adjacent second limiting protruding teeth 24. The box body 19 is rotatably connected to a main shaft 26, and a plurality of limiting plug-in components 25 are fixedly connected to the main shaft 26. The limiting plug-in components 25 are plugged into the second tooth grooves one by one, and the main shaft 26 is used to rotate the limiting plug-in components 25 to disengage from the second tooth groove.

[0044] Furthermore, the inner wall surface of the box body 19 is fixedly connected to the first limiting protruding teeth 23, and a plurality of the first limiting protruding teeth 23 are arranged side by side in the vertical direction, and a first tooth groove is formed between two adjacent first limiting protruding teeth 23, and the number of the first tooth grooves is equal to that of the second tooth grooves, and they are symmetrically arranged on both sides of the main shaft 26;

[0045] The limiting connector 25 has a short side and a long side on both sides of the main shaft 26, and the length of the long side is greater than the short side. The long side of the limiting connector 25 is located in the second tooth groove, and the short side of the limiting connector 25 is located in the first tooth groove; the main shaft 26 is used to rotate so that the long side and the short side of the limiting connector 25 are alternately positioned, and when the long side of the limiting connector 25 is located in the first tooth groove, its short side is spaced apart from the second limiting convex tooth 24.

[0046] The first limiting protruding teeth 23 and the second limiting protruding teeth 24 are distributed on both sides of the main shaft 26. The first limiting protruding teeth 23 and the second limiting protruding teeth 24 are the same in number and the same in spacing. The vertical arrangement structure corresponds to each other and is symmetrical. The main shaft 26 is vertically arranged. The number of the first tooth groove, the second tooth groove and the limiting plug-in 25 is the same. The first tooth groove and the second tooth groove are respectively arranged on both sides of a limiting plug-in 25. The main shaft 26 passes through a plurality of limiting plug-ins 25. The position where the main shaft 26 passes through the limiting plug-in 25 is the rotation center of the limiting plug-in 25. The limiting plug-in 25 is divided into a short side and a long side on both sides of the rotation center. The distance between the long side and the main shaft 26 is longer, so the length of the long side is greater than the short side.

[0047] During the rotation of the main shaft 26, the long side and the short side of the limit plug-in component 25 pass through the first tooth groove and the second tooth groove alternately. Figure 2When the long side is located in the second tooth groove, the short side is located in the first tooth groove. At this time, the limiting connector 25 supports the second tooth groove, thereby supporting the second limiting convex tooth 24. The plurality of limiting connectors 25 form a stable supporting function for the slide plate 21, thereby locking the slide plate 21. The short side is supported by the first tooth groove. The first tooth groove realizes the supporting function for the limiting connector 25, so that the structure of the limiting connector 25 is stable, and the deformation of the limiting connector 25 due to pressure can be avoided, and the limiting connector 25 can be avoided from slipping on the main shaft 26. The limiting connector 25 and the main shaft 26 can be welded. The design of the first tooth groove and the second tooth groove can prevent the welding part between the limiting connector 25 and the main shaft 26 from being easily damaged. When the long side is located in the first tooth groove, since the short side is shorter, the short side and the second tooth groove form a gap, so the slide plate 21 is unlocked, and the slide plate 21 can be raised and lowered to adjust the height.

[0048] The limiting plug connector 25 can be a plate, a rod, an axle, etc. The box 19 can be fixedly connected to the fixing frame 32, the main shaft 26 is arranged in the fixing frame 32, and the inner side of the fixing frame 32 is fixedly connected to the first limiting protruding tooth 23.

[0049] The present invention realizes unlocking and locking of the slide plate 21 by the rotation of the main shaft 26. For the rotation of the main shaft 26, a motor can be installed at the bottom of the housing 19, and the bottom of the main shaft 26 passes through the housing 19 and is connected to the motor output end, thereby realizing the rotation of the main shaft 26. A gear box 28 can also be fixedly connected to the bottom of the housing 19, and a vertical bevel gear 30 and a horizontal bevel gear 27 are arranged in the gear box 28. The bottom of the main shaft 26 passes through the bottom of the housing 19 and enters the gear box 28; the axis of the horizontal bevel gear 27 is vertical, and it is fixedly connected to the bottom of the main shaft 26. The axis of the vertical bevel gear 30 is horizontal, and it is fixedly connected to the operating shaft 29. The vertical bevel gear 30 and the horizontal bevel gear 27 are meshed. The axis of the operating shaft 29 is horizontal, and it can rotatably pass through the gear box 28, and a handle is provided. By rotating the operating shaft 29, the rotation of the main shaft 26 is realized. The operating shaft 29 passes through the inside of the lower section 2 and extends outside the lower section 2 to facilitate operation.

[0050] Furthermore, it also includes a rotating shaft 10, one end of which is rotatably connected to the side of the connecting frame 11, and the sliding seat 7 is provided with a through hole larger than the rotating shaft 10, the rotating shaft 10 passes through the through hole, and the inner wall surface of the through hole is fixedly connected to a plurality of wedge blocks 33; a plurality of the wedge blocks 33 are distributed around the rotating shaft 10 and are located between the rotating shaft 10 and the inner wall surface of the through hole;

[0051] A plurality of fixed terminals 35 are fixedly connected to the rotating shaft 10, and the positions of the plurality of fixed terminals 35 correspond one-to-one to the plurality of wedge blocks 33, and the fixed terminals 35 respectively abut against the corresponding wedge blocks 33; friction damping is formed between the fixed terminals 35 and the wedge blocks 33, and the rotating shaft 10 is used to rotate to adjust the damping size.

[0052] like Figure 4-Figure 6 The end of the fixed terminal 35 is fixedly connected to the elastic head 36 , and the elastic head 36 abuts against the wedge block 33 .

[0053] The perforation is a through-hole structure, and an annular gap is formed between the rotating shaft 10 and the perforation, and the wedge block 33 is located in the gap. A plurality of wedge blocks 33 are evenly distributed around the circumference of the rotating shaft 10. The number of the fixed terminals 35 is the same as that of the wedge blocks 33. The wedge-shaped arc surface of the wedge block 33 faces the rotating shaft 10, and its wedge-shaped arc surface abuts against the elastic head 36 of the fixed terminal 35, and the width of the wedge-shaped arc surface is greater than the width of the fixed terminal 35. When the rotating shaft 10 is rotated, the elastic head 36 moves on the wedge-shaped arc surface of the wedge block 33. Since the distance distribution of the wedge-shaped arc surface from the rotating shaft 10 in the circumferential direction of the rotating shaft 10 gradually changes, the extrusion force between the elastic head 36 and the wedge block 33 becomes larger or smaller. The present invention preferably adopts a solution in which the extrusion force between the elastic head 36 and the wedge block 33 becomes larger when the rotating shaft 10 is rotated counterclockwise. Therefore, the friction damping between the elastic head 36 and the wedge block 33 becomes larger and larger.

[0054] The sliding damping of the slide 7 can be adjusted by adjusting the friction damping between the elastic head 36 and the wedge block 33. When the locking state of the slide plate 21 and the adjustment sleeve 39 is released, under the action of the sliding damping of the slide 7, the lower roller 14 slowly descends, and the slide 7 slowly moves. The movement speed of the two can be changed by adjusting the damping of the slide 7.

[0055] In the axial direction of the rotating shaft 10, the fixed terminal 35 and the elastic head 36 are in a long strip structure, and the length thereof is much longer than the length of the sliding seat 7. The sliding seat 7 is preferably a cubic structure, and can be connected to the fixing plate 8 via a slide rail. Figure 6 For the sake of convenience, a dotted circle is used to express a part of the slide seat 7.

[0056] Furthermore, the side of the fixed terminal 35 is fixedly connected to a pin 37, and one end of the wedge block 33 is fixedly connected to a limit block 34, and the limit block 34 is provided with a pin hole adapted to the pin 37; the pin 37 is used to rotate with the rotating shaft 10 to be inserted into the pin hole, thereby forming an axial constraint on the slide seat 7.

[0057] Figure 5In the embodiment, the distance between one end of the wedge block 33 and the rotating shaft 10 is large, and the distance between the other end and the rotating shaft 10 is small. The stop block 34 is preferably arranged at the end where the distance between the wedge block 33 and the rotating shaft 10 is larger. The pin hole is located on the movement path of the latch 37. When the rotating shaft 10 rotates until the latch 37 is inserted into the pin hole, the slide 7 is locked. Therefore, in the present invention, the rotating shaft 10 rotates counterclockwise continuously, and the damping of the slide 7 gradually increases until it is locked.

[0058] In the axial direction of the rotating shaft 10 , a plurality of latches 37 are arranged side by side.

[0059] The embodiments described above are only descriptions of the preferred modes of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
