Description

Technical Field

[0002] As the permanent lining structure of the shield tunnel, the segment plays a vital role, which is directly related to the overall quality and service life of the shield tunnel. When installing the segment, it is necessary to lift the segment for transportation by a hoist.

[0003] When existing pipe segment lifting equipment is being lifted, if it is hit, the lifting clamp will tilt, and the pipe segment will slide in the tilting direction or even fall. Therefore, when people lift the pipe segment, they manually install a number of fixing bolts on the basis of clamping the pipe segment by its own gravity. The fixing bolts abut against the surface of the pipe segment to limit and fix the pipe segment to prevent it from tilting and falling. However, the operation of manually installing a number of fixing bolts is cumbersome, and it needs to be installed before each lifting.

When the crane drives the equipment to descend, the clamping frame descends and drives the extrusion block to contact the upper surface of the pipe segment first. At this time, the equipment descends under the action of gravity. The reaction force provided by the pipe segment squeezes the extrusion block into the second fixed cylinder, and presses the air into the water tank. The water tank is filled with water. The water is sprayed out through the nozzle and sprayed onto the surface of the pipe segment. On the one hand, it can wash away the sand, gravel and dust attached to the surface of the pipe segment. On the other hand, it can improve the sealing effect of the suction cup when it contacts the pipe segment later, and enhance the adsorption force of the suction cup.

[0023] 4. In the process of lifting the pipe segment, the present invention does not need to manually install multiple fixing bolts to fix the pipe segment. It can also have a better anti-slip function during the pipe segment lifting process, and is more efficient and convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0041] In one embodiment, Figure 1-Figure 15 As shown, a roller-type horizontal segment hoisting equipment comprises a fixing frame 1, a beam 3 is fixedly connected between two fixing frames 1, two symmetrical clamping frames 13 are slidably connected to the upper surface of the beam 3, a plurality of rollers 25 are arranged in the clamping frame 13, the rollers 25 abut against the beam 3, and further comprises an anti-slip assembly 49, a suction cup assembly 50, and a spraying assembly 51, a lifting rod 26 is slidably connected through the clamping frame 13, a lifting block 11 is fixedly connected to the top of the lifting rod 26, and two symmetrical connecting rods 4 are rotatably connected to the side wall of the lifting block 11 through a pin shaft, and a lifting ring 5 is arranged to rotate together with the four connecting rods 4, and a support plate 14 is fixedly connected to the lower end of the lifting rod 26;

[0042] The anti-slip assembly 49 is arranged on the side wall of the clamping frame 13 to prevent the pipe segment from slipping from the side;

[0043] The suction cup assembly 50 is arranged below the cross beam 3 and is used for sucking and fixing the pipe segment;

[0044] The spray assembly 51 is disposed below the cross beam 3 to improve the adsorption effect of the suction cup assembly 50 .

[0045] In one embodiment, Figure 7 As shown, the lifting ring 5 is connected to the rotating shaft 6 through a bearing, and the rotating shaft 6 is fixedly connected to a lever 7 and a locking hook 8 on its circumference. Two fixing plates 9 are fixedly connected to the upper surface of the crossbeam 3, and a locking rod 10 is fixedly connected between the two fixing plates 9.

[0046] The lever 7 is rotated, and the lever 7 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the locking hook 8 to rotate, so that the recessed part of the locking hook 8 hangs on the locking rod 10, so that when the crane lifts the lifting ring 5, the two connecting rods 4 maintain the maximum opening angle. At this time, the two clamping frames 13 are located at the farthest position, ensuring that the pipe segment is located between the two clamping frames 13 when the crane lowers the equipment.

[0047] In one embodiment, Fig.12 and Fig.13 As shown, the anti-slip assembly 49 includes a clamping plate 27 and a friction block 37. The clamping frame 13 has a side wall fixedly connected with the clamping plate 27. The side wall of the clamping plate 27 is provided with a friction block groove. The inner wall of the friction block groove is slidably connected with the friction block 37. The side wall of the clamping plate 27 is provided with two symmetrical block grooves. The inner wall of the block groove is slidably connected with a block 38. The side wall of the friction block 37 is fixedly connected with two symmetrical extrusion blocks 45. The extrusion blocks 45 are slidably connected with the clamping plate 27. The side wall of the block 38 is provided with an inclined surface. The side wall of the extrusion block 45 is provided with an inclined surface. The inclined surface of the extrusion block 45 is in contact with the inclined surface of the block 38. The inner wall of the block groove is provided with a spring groove 46. A spring is fixedly connected between the block 38 and the spring groove 46.

[0048] When the equipment is collided or shaken, the pipe segment abuts against the clamping plate 27. When the pipe segment tends to slide left or right, the friction block 37 will be driven to move left or right. The movement of the friction block 37 will drive the extrusion block 45 to move. The inclined surface of the extrusion block 45 cooperates with the inclined surface of the abutment block 38, so that the abutment block 38 is pushed out of the abutment block groove, automatically increasing the pressure on the side wall of the pipe segment to prevent the pipe segment from slipping.

[0049] In one embodiment, Figure 8 , Fig.10 , Fig.11 As shown, the suction cup assembly 50 includes a suction cup 17 and a lifting cylinder 39, the cross beam 3 is provided with an assembly hole 24, the inner side wall of the assembly hole 24 is fixedly connected to two symmetrical suction boxes 28, the lower surface of the suction box 28 is fixedly connected to the fixed cylinder 18, the inner side wall of the fixed cylinder 18 is slidably connected to the lifting cylinder 39, the lower surface of the lifting cylinder 39 is fixedly connected to the suction cup 17, a spring is fixedly connected between the lifting cylinder 39 and the inner side wall of the fixed cylinder 18, a first air hole 42 is provided in the suction box 28, the first air hole 42 is connected to the fixed cylinder 18, a baffle groove is provided on the upper surface of the suction box 28, the baffle groove is connected to the first air hole 42, the inner side wall of the baffle groove is rotatably connected to the baffle 44 through a pin shaft, an L-shaped plate 19 is fixedly connected to the upper surface of the suction box 28, and a spring is fixedly connected between the L-shaped plate 19 and the baffle 44.

[0050] When the crane continues to descend, the suction cup 17 contacts the upper surface of the pipe segment and is squeezed into the fixed tube 18 by the reaction force of the pipe segment, so that the air in the fixed tube 18 pushes the baffle 44 open and is discharged to the outside. The spring force between the L-shaped plate 19 and the baffle 44 is smaller than the spring force between the second sliding plate 40 and the second air hole 43, so the air in the fixed tube 18 will not squeeze the second sliding plate 40. When the lifting tube 39 is completely moved into the fixed tube 18, the suction cup 17 completes the adsorption of the pipe segment.

[0051] In one embodiment, Figure 8 , Fig. 9 , Fig.10 As shown, a second air hole 43 is opened in the air suction box 28, and the second air hole 43 is communicated with the first air hole 42. A second sliding plate 40 is slidably connected to the inner wall of the second air hole 43, and a second stopper 41 is fixedly connected to the inner wall of the second air hole 43. A spring is fixedly connected between the second sliding plate 40 and the inner wall of the second air hole 43. A hose 22 is connected to the side wall of the air suction box 28, and the hose 22 is communicated with the second air hole 43. A first fixed cylinder 29 is fixedly connected to the side wall of the clamping plate 27, and the first fixed cylinder 29 is communicated with the hose 22. A second The pull rope cavity, the second pull rope cavity is connected to the friction block groove, the second pull rope 34 is fixedly connected to the upper surface of the friction block 37, the second pull rope 34 extends through the second pull rope cavity to the first fixed cylinder 29, the first fixed cylinder 29 inner wall is slidably connected with the first sliding plate 35, the first fixed cylinder 29 inner wall is fixedly connected with the first stopper 36, a spring is fixedly connected between the first sliding plate 35 and the inner wall of the first fixed cylinder 29, the first sliding plate 35 is connected to the second pull rope 34, the first fixed cylinder 29, the hose 22, and the second air hole 43 are filled with hydraulic oil.

[0052] When the clamping plate 27 moves, it will pull the second pull rope 34, and the second pull rope 34 will pull the first stop block 36. The first stop block 36 moves, causing the hydraulic oil to move in the direction of the first stop block 36. At this time, the hydraulic oil in the second air hole 43 will also move. At this time, the second sliding plate 40 will also move, squeezing the spring. When the second sliding plate 40 moves, the gas in the first air hole 42 will be sucked into the second air hole 43, increasing the adsorption force of the suction cup 17 on the surface of the pipe segment, further preventing the pipe segment from slipping.

[0053] In one embodiment, Fig.14As shown, the spray assembly 51 includes an extrusion block 31 and a second fixed cylinder 32, the second fixed cylinder 32 is fixedly connected to the lower surface of the cross beam 3, the inner wall of the second fixed cylinder 32 is penetrated and slidably connected with the extrusion block 31, a spring is fixedly connected between the extrusion block 31 and the inner wall of the second fixed cylinder 32, the lower surface of the suction box 28 is fixedly connected to the water tank 21, the second fixed cylinder 32 is connected to the two water tanks 21 through the air pipe 33, the lower surface of the water tank 21 is fixedly connected to the assembly plate 23, the side wall of the water tank 21 is penetrated by a nozzle 30, one end of the nozzle 30 is penetrated and fixedly connected to the assembly plate 23, and the side wall of the water tank 21 is provided with a water inlet.

[0054] When the crane drives the equipment to descend, the clamping frame 13 descends and drives the extrusion block 31 to contact the upper surface of the pipe segment first. At this time, the equipment descends under the action of gravity. The reaction force provided by the pipe segment squeezes the extrusion block 31 into the second fixed cylinder 32, and presses the air into the water tank 21. The water tank 21 is filled with water. The water is sprayed out through the nozzle 30 and sprayed on the surface of the pipe segment. On the one hand, it can wash away the sand and dust attached to the surface of the pipe segment. On the other hand, it can improve the sealing effect of the suction cup 17 when it contacts the pipe segment later, and enhance the suction force of the suction cup. When the suction cup 17 is wet, water molecules can fill the tiny gap between the suction cup 17 and the surface of the pipe segment to form a tighter seal.

[0055] In one embodiment, Figure 3 and Fig.15 As shown, a pull rod frame 15 is fixedly connected to the upper surface of the fixed frame 1, one side of the pull rod frame 15 is open, and a pull rod 12 is slidably arranged through the inner wall of the pull rod frame 15, a first pull rope 16 is fixedly connected to the upper surface of the baffle 44, and the other end of the first pull rope 16 is connected to the pull rod 12, a limiting ring 48 is arranged around the pull rod 12, and the limiting ring 48 is slidably connected to the inner wall of the pull rod frame 15.

[0056] The pull rod 12 is manually pulled, and the pull rod 12 pulls the two baffles 44, so that the two baffles 44 are turned over, and the outside air enters the first air hole 42, so that the suction cup 17 no longer absorbs the pipe segment, and the pipe segment is removed.

[0057] In one embodiment, Figure 1 and Figure 3 As shown, an anti-collision wheel 2 is arranged at the bottom of the fixing frame 1.

[0058] The above embodiment discloses a roller type segment horizontal lifting device.

[0059] The specific working principle and process are as follows:

[0060] S1: Manually rotate the lever 7, the lever 7 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the locking hook 8 to rotate, so that the recessed part of the locking hook 8 hooks the locking rod 10, so that when the crane lifts the lifting ring 5, the two connecting rods 4 maintain the maximum opening angle. At this time, the two clamping frames 13 are located at the farthest position, ensuring that when the crane lowers the equipment, the pipe segment is located between the two clamping frames 13.

[0061] S2: When the crane drives the equipment to descend, the clamping frame 13 descends and drives the extrusion block 31 to contact the upper surface of the pipe segment first. At this time, the equipment descends under the action of gravity. The reaction force provided by the pipe segment squeezes the extrusion block 31 into the second fixed cylinder 32, and presses the air into the water tank 21. The water tank 21 is filled with water. The water is sprayed out through the nozzle 30 and sprayed onto the surface of the pipe segment. On the one hand, it can wash away the sand and dust attached to the surface of the pipe segment. On the other hand, it can improve the sealing effect of the suction cup 17 when it contacts the pipe segment later, and enhance the suction force of the suction cup. When the suction cup 17 is wet, water molecules can fill the tiny gap between the suction cup 17 and the surface of the pipe segment to form a tighter seal;

[0062] S3: When the crane continues to descend, the suction cup 17 contacts the upper surface of the pipe segment. At this time, the suction cup 17 is squeezed into the fixed cylinder 18 by the reaction force of the pipe segment, so that the air in the fixed cylinder 18 pushes the baffle 44 open and is discharged to the outside. The spring force between the L-shaped plate 19 and the baffle 44 is smaller than the spring force between the second sliding plate 40 and the second air hole 43, so the air in the fixed cylinder 18 will not squeeze the second sliding plate 40. When the lifting cylinder 39 is completely moved into the fixed cylinder 18, the suction cup 17 has completed the adsorption of the pipe segment.

[0063] S4: Manually rotate the lever 7 so that the concave part of the lock hook 8 no longer hooks the lock rod 10. At this time, the crane pulls the lifting ring 5. Under the action of the equipment's own gravity, the connecting rod 4 drives the two lifting blocks 11 to move closer to the middle, and the lifting blocks 11 drive the two clamping frames 13 to move closer to the middle. The two clamping frames 13 clamp the pipe segment. When the clamping plates 27 on the side walls of the clamping frames 13 abut against the side surfaces of the pipe segment, the connecting rod 4 pulls the lifting blocks 11 to move upward, and the lifting blocks 11 mobilize the two supporting plates 14 to move upward, dragging the bottom of the pipe segment to complete the lifting operation;

[0064] S5: When the equipment is hit or shaken, the pipe segment abuts against the clamping plate 27. When the pipe segment has a tendency to slide left or right, the friction block 37 will be driven to move left or right. The movement of the friction block 37 will drive the extrusion block 45 to move. The inclined surface of the extrusion block 45 cooperates with the inclined surface of the abutment block 38, so that the abutment block 38 is pushed out of the abutment block groove, automatically increasing the pressure on the side wall of the pipe segment to prevent the pipe segment from slipping off.

[0065] When the clamping plate 27 moves, the second pull rope 34 is pulled, and the second pull rope 34 pulls the first stopper 36. The first stopper 36 moves so that the hydraulic oil moves in the direction of the first stopper 36. At this time, the hydraulic oil in the second air hole 43 also moves. At this time, the second sliding plate 40 also moves, squeezing the spring. When the second sliding plate 40 moves, the gas in the first air hole 42 is sucked into the second air hole 43, increasing the adsorption force of the suction cup 17 on the surface of the pipe segment, further preventing the pipe segment from slipping off;

[0066] S6: When the crane reaches the segment installation position, it places the segment on the designated installation frame. At this time, the fixing frame 1 contacts the ground, the connecting rod 4 descends to drive the support plate 14 to descend, and drives the two clamping frames 13 to move to both sides to release the clamping of the segment. The recessed part of the locking hook 8 is automatically stuck with the locking rod 10 under the action of gravity. The pull rod 12 is manually pulled, and the pull rod 12 pulls the two baffles 44 to make the two baffles 44 flip over, and the outside air enters the first air hole 42, so that the suction cup 17 no longer absorbs the segment, and the segment is removed. The operation is simple and does not require the help of external fixing bolts to firmly fix the segment, thereby preventing the segment from slipping and improving the transportation efficiency of the segment.

[0067] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
