Description

Technical Field

[0001] This application relates to the field of precast T-beams and arch ribs, and in particular to a device for lateral movement of T-beams and arch ribs. Background Technology

[0002] With the rapid development of highway engineering in my country, bridges of various structural types are constantly emerging. Steel-concrete composite bridges are widely used in engineering projects due to their simple construction process, short construction period, and good load-bearing performance. The arch ribs of a steel-concrete composite arch bridge are composed of arch columns made of steel pipes and T-beams. The T-beams are made of concrete cast on a platform. After casting, the structure is completed through processes such as formwork removal, tensioning, grouting, and anchor sealing. The structure is then moved to a beam storage area for storage.

[0003] The existing method uses steel wire ropes to lift the T-beam and arch ribs, passing the steel wire ropes through the pre-drilled holes at the top of the T-beam and the base of the T-beam, and then lifts and moves the T-beam and arch ribs laterally to the beam storage area.

[0004] The existing technical solutions mentioned above have the following drawbacks: friction between the wire rope and the T-beam causes wear on the wire rope, shortening its service life. When the columns on the arch are hoisted and moved, the wire rope will rub against the surface of the steel pipe arch rib, causing the paint to peel off and reducing the rust resistance of the steel pipe arch rib. Utility Model Content

[0005] In order to reduce wear on wire ropes and structures, and to ensure the quality of structures and projects, this application provides a device for the lateral movement of T-beams and arch ribs.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A device for lateral movement of T-beams and arch ribs includes a fixed frame with a crossbar fixed to it. Two adjusting rods are slidably disposed within the crossbar. One end of each adjusting rod is machined into an adjusting rack, the sidewalls of which are in contact with each other. An adjusting assembly connected to the adjusting rack is disposed on the adjusting rod. Two sliding rods are disposed within the fixed frame. A first sling is connected to the fixed frame, one end of which is connected to a stabilizing frame. A second sling for connection to a gantry crane is connected to the sliding rod. One end of the sliding rod is connected to one end of the adjusting rod, and a connecting rod is connected to the first adjusting rod. Multiple first fixing holes are spaced apart on the sliding rod, and steel wire ropes for hoisting the arch ribs are connected to the first fixing holes.

[0008] By adopting the above technical solutions, the stabilizing frame can increase the overall structural stability of the transverse movement device, reduce the deformation of the transverse movement device after changing the position of the two ends of the wire rope connected to the transverse movement device, and ensure the stability of the transverse movement device and the structure during the hoisting operation. By adjusting the position of the two wire ropes fixed at the first fixing holes located at both ends of the length direction of the stabilizing frame, the distance between the wire rope and the side wall of the T-beam or arch rib to be hoisted is adjusted so that the wire rope moves away from the side wall of the T-beam or arch rib after hoisting the T-beam or arch rib, reducing the friction between the wire rope and the T-beam or arch rib after hoisting the T-beam or arch rib, reducing the wear of the wire rope and the structure, ensuring the quality of the structure, and ensuring the quality of the project.

[0009] Optionally, the adjusting assembly includes a fixed box fixed to the crossbar. A motor is installed inside the fixed box, and the output shaft of the motor is connected to a first transmission rod. One end of the first transmission rod is rotatably connected to the fixed box, and one end of the first transmission rod is connected to a first gear via a key. A first bevel gear is sleeved on one end of a first transmission shaft. The first bevel gear meshes with a transmission bevel gear, and the transmission bevel gear meshes with a second bevel gear. The second bevel gear is connected to a second transmission rod via a key, and one end of the second transmission rod is rotatably connected to the fixed box. A second gear is connected to the second transmission rod via a key. The first gear meshes with one of the adjusting racks, and the second gear meshes with another adjusting rack.

[0010] By adopting the above technical solution, it is possible to push two adjusting rods to extend or retract from the fixed frame and push two sets of sliding rods to extend or retract from the fixed frame, thereby moving the U-shaped clip fixed at the first fixed hole to finely adjust the distance between the two ends of the wire rope, increase the accuracy of the distance adjustment between the two ends of the wire rope, ensure that the wire rope is away from the side wall of the structure, reduce the angle between the wire rope and the structure, reduce the load weight of the wire rope, and ensure the stability of the transverse device when lifting the structure.

[0011] Optionally, the connecting rod is provided with a plurality of second fixing holes at intervals.

[0012] By adopting the above technical solution, bolts are inserted into the second fixing hole according to the length of the T-beam or arch rib, and U-shaped clips and nuts are connected to the wire ropes connected to the T-beam or arch rib. This can increase the stability of the connection between the T-beam or arch rib and the transverse movement device, ensure the stability of the transverse movement device and the structure during the hoisting operation, and increase the overall stability of the transverse movement device.

[0013] Optionally, a bolt is inserted into the first fixing hole, a U-shaped clip is inserted into the bolt, a nut is threaded onto the bolt, and the U-shaped clip is connected to the wire rope.

[0014] By adopting the above technical solution, it is possible for workers to change the spacing between the two ends of the wire rope according to the T-beam or arch rib, while ensuring a stable connection between the wire rope and the lateral movement device and reducing wire rope wear.

[0015] Optionally, one end of the sliding rod is machined into a guide rack, and a guide gear is rotatably disposed inside the fixing frame, the guide gear meshing with two guide racks.

[0016] By adopting the above technical solution, the two sliding rods can move simultaneously in opposite or opposite directions, ensuring that the two sets of sliding rods can extend at the same time and ensuring the overall stability of the transverse movement device.

[0017] Optionally, a stabilizing cable connects the stabilizing frame and the fixed frame.

[0018] By adopting the above technical solutions, the stabilizing cable can increase the overall structural stability of the transverse movement device, reduce the deformation of the transverse movement device after the positions of the two ends of the wire rope connected to the transverse movement device are changed, and ensure the stability of the transverse movement device and the structure during the hoisting operation.

[0019] Optionally, a first limiting block is machined at one end of the adjusting rack.

[0020] By adopting the above technical solution, the first limiting block can reduce the danger caused by the adjusting rack disengaging from the second gear.

[0021] Optionally, a second limiting block is machined at one end of the guide rack.

[0022] By adopting the above technical solution, the second limiting block can reduce the danger caused by the guide rack disengaging from the guide gear.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up a stabilizing frame, crossbar, adjusting components, and sliding rod, the overall structural stability of the lateral movement device can be increased, ensuring the stability of the lateral movement device and the structure during the hoisting operation. This allows the wire rope to move away from the side wall of the T-beam or arch rib after hoisting it, reducing friction between the wire rope and the T-beam or arch rib, reducing wear on the wire rope and the structure, and ensuring the quality of the structure and the project.

[0025] 2. By setting up stabilizing cables, the overall structural stability of the traverse device can be increased, the deformation of the traverse device after changing the position of the two ends of the wire rope connected to the traverse device can be reduced, and the stability of the traverse device and the structure can be ensured during the hoisting operation.

[0026] 3. By setting the first limit block and the second limit block, the dangers caused by the adjusting rack disengaging from the second gear and the guide rack disengaging from the guide gear can be reduced, ensuring the stability of the lateral movement device and the structure during the hoisting operation.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a device for the lateral movement of T-beams and arch ribs, referring to... Figure 1 The device includes a fixed frame 1, which is made of four square tubes welded together and is rectangular. A crossbar 11 is welded on the fixed frame 1 along its length. An adjusting rod 12 is slidably arranged inside the crossbar 11. Two adjusting rods 12 are arranged at intervals along the length of the crossbar 11.

[0034] Reference Figure 2 The two adjusting rods 12 are each machined with an adjusting rack 121 at their close ends. The adjusting rack 121 is arranged along the length of the crossbar 11, and the two adjusting racks 121 are spaced apart along the width of the crossbar 11. The end of the adjusting rack 121 away from the adjusting rod 12 is machined with a first limiting block 122. An adjusting component 2 is provided on the crossbar 11. The adjusting component 2 is located at the connection of the two adjusting racks 121 and is connected to the two adjusting racks 121.

[0035] Reference Figure 2The adjusting assembly 2 includes a fixed box 21, which is welded to a crossbar 11. The top of the connection between the crossbar 11 and the fixed box 21 communicates with the interior of the fixed box 21. A motor 22 is installed at the bottom of the fixed box 21. The output shaft of the motor 22 is connected to a first transmission rod 23 via a key. The end of the first transmission rod 23 away from the motor 22 is rotatably connected to the side wall of the fixed box 21 away from the motor 22. The end of the first transmission rod 23 away from the motor 22 is connected to a first gear 24 via a key. A first bevel gear 25 is fitted onto the end of the first transmission shaft away from the first gear 24. The first bevel gear 25 is connected to the first transmission shaft via a key, and the first bevel gear 25 meshes with a transmission bevel gear 26. A transmission bevel gear 26 is rotatably mounted on the top of the inner wall of the fixed box 21. A second bevel gear 27 meshes with the side of the transmission bevel gear 26 away from the first bevel gear 25. A second transmission rod 28 is welded to the side of the second bevel gear 27 away from the first bevel gear 25. The end of the second transmission rod 28 away from the motor 22 is rotatably connected to the side wall of the fixed box 21 away from the motor 22. The second transmission rod 28 is sleeved and rotatably connected to the peripheral wall of the first transmission rod 23.

The first gear 24 meshes with the adjusting rack 121 away from the motor 22, and the second gear 29 meshes with the adjusting rack 121 close to the motor 22.

[0036] Reference Figure 1 A sliding rod 13 is provided inside the fixed frame 1 along its length direction. Two sliding rods 13 are provided and are respectively provided in the square tubes on both sides of the fixed frame 1 along its length direction. Each pair of sliding rods 13 forms a group. Two groups are symmetrically arranged on the fixed frame 1 along its width direction. One end of the sliding rod 13 is slidably disposed inside the fixed frame 1, and the other end extends out of the side wall on one side of the fixed frame 1 along its length direction. A connecting rod 14 is connected between the ends of each group of sliding rods 13 that extend out of the fixed frame 1. The connecting rod 14 is welded to the sliding rod 13. The opposite ends of two adjusting rods 12 are respectively welded to their adjacent connecting rods 14. A number of first fixing holes 131 are opened at intervals on the section of the sliding rod 13 that extends out of the fixed frame 1. A number of second fixing holes 141 are opened at intervals along its length direction on the connecting rod 14. The diameter of the second fixing holes 141 is the same as that of the first fixing holes 131.

[0037] Reference Figure 1 and Figure 3 A bolt 3 is inserted into the first fixing hole 131 away from the fixing frame 1. A U-shaped clip 31 is inserted into the bolt 3. The two ends of the U-shaped clip 31 are located at the two ends of the first fixing hole 131. A nut 32 is threaded to the end of the bolt 3 away from its large end. Two U-shaped clips 31 connected to a set of sliding rods 13 are connected to steel wire ropes 4 for hoisting T-beams or arch ribs. One end of the steel wire rope 4 is connected to the two U-shaped clips 31 connected to a set of sliding rods 13, and the other end of the steel wire rope 4 is connected to the two U-shaped clips 31 connected to another set of sliding rods 13.

[0038] The wire rope 4 is connected to the transverse movement device by bolts 3, nuts 32 and U-shaped clips 31, which makes it easy for workers to change the distance between the two ends of the wire rope 4 according to the T-beam or arch rib, while ensuring a stable connection between the wire rope 4 and the transverse movement device and reducing wear on the wire rope 4.

[0039] Reference Figure 4 Each of the two sets of sliding rods 13 has a guide rack 132 machined at one end facing each other. A guide gear 133 is rotatably arranged inside the fixed frame 1. A second limiting block 134 is machined at the end of the guide rack 132 away from the sliding rod 13. There are two guide gears 133, which are located between the two sets of guide racks 132 respectively, and the guide gears 133 mesh with the two guide racks 132 that are close to them.

[0040] Reference Figure 1 The top of the sliding rod 13, away from the fixed frame 1, is connected to a first sling 5. The ends of the four first slings 5 ​​away from the sliding rod 13 are connected to a stabilizing frame 6. The four bottom corners of the stabilizing frame 6 are respectively connected to the nearest first sling 5. The four top corners of the fixed frame 1 are all connected to stabilizing cables 7. The ends of the four stabilizing cables 7 away from the fixed frame 1 are connected to the four bottom corners of the stabilizing frame 6. The four top corners of the stabilizing frame 6 are all connected to second slings 8. The ends of the four second slings 8 away from the stabilizing frame 6 are connected together and connected to the gantry crane.

[0041] When using the device for lateral movement of T-beams and arch ribs, the gantry crane is connected to the second lifting cable 8 and the lateral movement device is lifted. The stabilizing frame 6 and the stabilizing cable 7 can increase the overall structural stability of the lateral movement device, reduce the deformation of the lateral movement device after the positions of the two ends of the wire rope 4 connected to the lateral movement device are changed, and ensure the stability of the lateral movement device and the structure during the hoisting operation. By adjusting the position of the two wire ropes 4 fixed at the first fixing holes 131 located at both ends of the length direction of the fixing frame 1, the distance between the wire rope 4 and the side wall of the T-beam or arch rib to be lifted is adjusted so that the wire rope 4 is away from the side wall of the T-beam or arch rib after lifting the T-beam or arch rib, reducing the friction between the wire rope 4 and the T-beam or arch rib after lifting the T-beam or arch rib, reducing the wear of the wire rope 4 and the structure, ensuring the quality of the structure, and ensuring the quality of the project.

[0042] The control motor 22 rotates, driving the first transmission rod 23 and the first gear 24 to rotate, causing the adjusting rack 121 and adjusting rod 12 meshing with the first gear 24 to move. At the same time, the first bevel gear 25 on the first transmission rod 23 rotates, driving the transmission bevel gear 26 and the second bevel gear 27 to rotate, thereby driving the second transmission rod 28 and the second gear 29 connected to the second bevel gear 27 to rotate, pushing the adjusting rack 121 and adjusting rod 12 meshing with the second gear 29 to move. The first limiting block 122 can reduce the danger caused by the adjusting rack 121 disengaging from the second gear 29. The meshing of the guide gear 133 and the two guide racks 132 can make the two sliding rods 13 move simultaneously in opposite or opposite directions. The second limiting block 134 can reduce the danger caused by the guide rack 132 disengaging from the guide gear 133, ensuring that the two sets of sliding rods 13 can extend simultaneously, ensuring the overall stability of the transverse movement device.

[0043] By adjusting the component 2, the two adjusting racks 121 are pushed to move in opposite directions, which can push the two adjusting rods 12 to extend or retract from the fixed frame 1 and push the two sets of sliding rods 13 to extend or retract from the fixed frame 1. This causes the U-shaped clip 31 fixed at the first fixed hole 131 to move, so as to fine adjust the distance between the two ends of the wire rope 4, increase the accuracy of the distance adjustment between the two ends of the wire rope 4, ensure that the wire rope 4 is away from the side wall of the structure, reduce the angle between the wire rope 4 and the structure, reduce the load weight of the wire rope 4, and ensure the stability of the transverse device when lifting the structure.

[0044] According to the length of the T-beam or arch rib being lifted, bolts 3 are inserted into the second fixing hole 141, and U-shaped clips 31 and nuts 32 are connected to the wire ropes 4 connected to the T-beam or arch rib. This can increase the stability of the connection between the T-beam or arch rib and the transverse movement device, ensure the stability of the transverse movement device and the structure during the lifting operation, and increase the overall stability of the transverse movement device.

[0045] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
