Description

Technical Field

[0001] The invention relates to the technical field of bridges, and in particular to a bridge erecting machine beam transporting device for composite beam installation construction. Background Art

[0002] A bridge-erecting machine is a device that places prefabricated beams onto prefabricated bridge piers. Bridge-erecting machines belong to the category of cranes because their main function is to lift the beams, transport them to the location and then lower them. Bridge-erecting machines are divided into several types, such as those for erecting highway bridges, conventional railway bridges, and passenger-dedicated railway bridges. From installation, commissioning, operation, warehousing and storage, each link has strict management methods to ensure that the bridge-erecting machine is always in good technical condition.

[0003] When installing a combined installation beam, an existing bridge-building machine usually uses a lifting device on the bridge-building machine to lift the installation beam to the pier installation position, and transports the operator to the pier position by the lifting device. With the assistance of the operator, the installation beam is aligned with the pier installation hole for installation. This installation method requires the operator to perform construction under the installation beam lifted by the lifting device, and align the mounting seat at the bottom of the installation beam with the mounting hole on the pier for installation. In this working environment, since the sling is extended too long, it is easy to shake during the operation. The installation beam needs to be slowly lowered and installed by multiple people in collaboration. The installation progress is slow, and there are safety hazards to the personal safety of the operators during the installation. At the same time, after the installation is completed, it is necessary to spray waterproof paint on the arc surfaces on both sides of the bottom of the installation beam, and the operator needs to take a lift to spray, which wastes manpower and affects the construction progress of the bridge-building machine.

[0004] Therefore, the present application provides a bridge erection machine beam transport device for composite beam installation construction to meet the needs. Summary of the invention

In this working environment, since the sling is extended too long, it is easy to shake during the operation. The installation beam needs to be slowly lowered and installed by the cooperation of multiple people, and the installation progress is slow.

[0039] like Figures 1 to 9As shown, an embodiment of the present invention provides a bridge-erecting beam transporting device for composite beam installation construction, comprising an installation beam 1, drainage holes 2 are symmetrically arranged on both sides of the installation beam 1, four groups of installation frames 3 are equiangularly distributed at the top of the installation beam 1, a sling 4 is arranged at the top of each group of installation frames 3, two lifting bolts 5 are symmetrically arranged at the bottom end of the installation frame 3, eight installation shafts 9 are equiangularly distributed at the bottom end of the installation beam 1, a gear 10 is sleeved on the outer side of the installation shaft 9, and also includes an installation component 6, the installation component 6 is installed at an equiangular distribution at the bottom of the installation beam 1, the installation component 6 is used to install the installation beam 1, an auxiliary component 7, the auxiliary component 7 is installed on one side of the installation component 6, the auxiliary component 7 is used to assist the installation of the installation beam 1 on the bridge pier, and a spraying component 8, the spraying component 8 is installed on one side of the installation component 6, and the spraying component 8 is used to spray waterproof coating on the side wall of the installation beam 1.

[0040] like Figures 1 to 5 As shown, the mounting assembly 6 includes an elastic telescopic rod 61, which is mounted on the bottom of one side of the mounting frame 3, and the bottom end of the elastic telescopic rod 61 is connected to an electric push rod 62, and one side of the electric push rod 62 is connected to a connecting plate 63, and two screw rods 64 are symmetrically nested on the inner side of the connecting plate 63, and a contact plate 65 is connected between the two screw rods 64, and the outer side of the screw rod 64 is sleeved with a threaded sleeve 66, which is mounted on the bottom end of the mounting beam 1, and the outer side of the threaded sleeve 66 is sleeved with a gear shaft 67, and the top of the gear shaft 67 is connected to a pulley group 68;

[0041] By setting the installation component 6, the operator pulls the sling 4 through the lifting hole of the installation beam 1 by operating the lifting equipment of the bridge erection machine, and fixes the bolt to the outer side of the bottom end of the sling 5, so that the lifting equipment can lift the installation beam 1. When reaching the position of the pier to be installed, the operator on the pier controls the lifting equipment through the wireless remote control device to move the sling 4 downward, so that the sling 5 drives the installation beam 1 to move toward the pier, and the installation frame 3 also moves with it, and the contact plate 65 contacts with the top of the pier. As the installation beam 1 moves downward, the threaded sleeve 66 moves downward with it, and the threaded sleeve 66 is threadedly meshed with the screw 64. The threaded sleeve 66 rotates at the bottom end of the installation beam 1, and the threaded sleeve 66 drives the gear shaft 67 to rotate. Under the synchronous transmission of the pulley group 68, the gear shaft 67 located at the bottom end of the installation beam 1 is driven by the gear shaft 67. The two screw rods 64 on the same contact plate 65 are kept horizontal, and the gear shaft 67 is meshed with the gear 10. The electric push rod 62 controls the left and right movement of the connecting plate 63 to align the installation shaft 9 with the pier hole, so that the installation shaft 9 is rotated to enter the pier hole to prevent the pier hole from being uneven and unable to fully enter the pier hole, so as to facilitate the operator to grout and fix the pier hole. As the installation beam 1 moves downward, the contact plate 65 and the connecting plate 63 gradually contact each other, and the elastic telescopic rod 61 connected between the mounting frame 3 and the electric push rod 62 is forced to shrink, thereby improving the installation alignment efficiency of the installation beam 1 and the pier, and preventing the pier hole from being uneven and impurities from being unable to fully enter the pier hole, resulting in cavities in the final grouting and fixing stage, thereby avoiding incomplete fixation.

[0042] like Figures 1 to 3 and Figures 6 to 8 As shown, the auxiliary component 7 includes a mounting seat 71, which is mounted on the top of the connecting plate 63, and the top of the mounting seat 71 is connected to an elastic telescopic rod 3 72, and the top of the elastic telescopic rod 3 72 is connected to a connecting rod 1 73, and the connecting rod 1 73 rotates at the end of the elastic telescopic rod 3 72, and the end of the connecting rod 1 73 is connected to a connecting rod 2 74, and the connecting rod 2 74 rotates at the end of the connecting rod 1 73, and an auxiliary roller 75 is installed at the end of the connecting rod 2 74, and one end of the connecting rod 2 74 is connected to a connecting rod 3 76, and the connecting rod 3 76 is connected to the connecting rod 3 The end of the second rod 74 rotates, the end of the third connecting rod 76 is connected to the fourth connecting rod 77, the fourth connecting rod 77 rotates at the end of the third connecting rod 76, the end of the fourth connecting rod 77 is connected to the rotating wheel 78, the inner side of the rotating wheel 78 is evenly distributed with elastic telescopic rods 4 79, the top of the elastic telescopic rods 4 79 is connected to the contact block 710, the surface of the contact block 710 is provided with an anti-skid layer, one side of the fourth connecting rod 77 is connected to the rack 1 711, the rack 1 711 and the gear 2 712 are meshed with each other, and the gear 2 712 is installed on one side of the second connecting rod 74;

[0043] By setting the auxiliary component 7, as the elastic telescopic rod 1 61 is forced to shrink, the auxiliary roller 75 and the rotating wheel 78 are at the bottom arc position of the mounting beam 1, and the elastic telescopic rod 4 79 inside the rotating wheel 78 is squeezed by the contact block 710 and the bottom of the mounting beam 1. The pressure is contracted, and as the mounting beam 1 moves downward, the connecting rod 4 77 rotates at the end of the connecting rod 3 76, driving the connecting rod 4 77 to drive the rotating wheel 78 to rotate in the direction of the drainage hole 2 on the corresponding side, and the rack 1 711 and the gear 2 712 are meshed with each other, so that the connecting rod 2 74 rotates in the direction close to the mounting shaft 9. The auxiliary roller 75 rolls on the arc surface of the mounting beam 1, and the connecting rod 2 74 drives the connecting rod 1 73 to rotate, so that the elastic telescopic rod 3 72 on the top of the mounting seat 71 contracts. When the rotating wheel 78 moves to the drainage hole 2, it enters the contact block 710 in the drainage hole 2. Since it is no longer blocked by the bottom wall of the mounting beam 1, the elastic telescopic rod 4 79 in contraction returns to its original state, so that the elastic telescopic rod 4 79 limits the connecting rod 4 77 on the inner side of the drainage hole 2, thereby improving the running stability of the spray assembly 8 and providing auxiliary positioning for the bottom end of the mounting beam 1, facilitating the installation of the mounting beam 1.

[0044] like Figures 1 to 3 and Fig. 9 As shown, the spray assembly 8 includes a ratchet 81, which is mounted on the end of the second connecting rod 74, and the ratchet 81 is coaxially mounted with the auxiliary roller 75, the ratchet 81 and the second rack 82 are meshed with each other, one end of the second rack 82 is connected with a spring 83, the tail end of the spring 83 is connected with a slide frame 84, the end of the second rack 82 is connected with a piston 1 85, the piston 1 85 slides on the inner side of the slide frame 84, the tail end of the one-way valve 86 is connected with a storage box 87, the storage box 87 is mounted on the top of the connecting plate 63, the top of the storage box 87 is mounted with a connecting rod 3 76, the inner side of the storage box 87 is mounted with a piston 2 88, the piston 2 88 slides on the inner side of the storage box 87, and the top end between the two groups of storage boxes 87 on the opposite side is connected with a spray rack 89;

[0045] By setting the spraying assembly 8, the auxiliary roller 75 rolls on the arc surface of the mounting beam 1, and the ratchet 81 coaxially connected to the auxiliary roller 75 rotates accordingly, and the ratchet 81 meshes with the rack 2 82. The piston 1 85 at the end of the rack 2 82 slides on the inner side of the slide rack 84 under the push of the rack 2 82, and the spring 83 is stretched by the force. The piston 1 85 pushes the waterproof coating in the pipeline to enter the interior of the storage box 87 through the one-way valve 86, and pushes the piston 2 88 to slide upward on the inside of the storage box 87, so that the spray rack 89 on the top of the two groups of storage boxes 87 on the same side sprays the waterproof coating on the arc surface of the mounting beam 1. When the elastic limit of the spring 83 is reached, the spring 83 returns to its original state, driving the rack 2 82 and the spring 83 to move. Plug 1 85 moves in the direction of returning to its original position. Due to the unidirectional transmission property of the ratchet 81, the ratchet 81 will not transmit the transmission to the auxiliary roller 75 during the resetting process of the rack 2 82. As the auxiliary roller 75 rolls on the arc surface of the mounting beam 1, the ratchet 81 continues to engage and transmit with the rack 2 82, so that the piston 1 85 pushes the waterproof coating in the pipeline and pushes the piston 2 88 to slide upward on the inside of the storage box 87. The two groups of storage boxes 87 on the same side push the waterproof coating located above the piston 2 88 into the inside of the spray rack 89, and the waterproof coating is sprayed from the spray rack 89 to continuously spray the arc surface of the mounting beam 1 with waterproof coating. No additional manpower is required for construction, which improves the construction efficiency of the bridge erection machine, speeds up the construction speed, and can effectively utilize construction resources.

[0046] The working principle of the technical solution provided by the present invention is as follows:

[0047] The operator pulls the sling 4 through the lifting hole of the installation beam 1 by operating the lifting equipment of the bridge erection machine, and fixes the bolt to the outer side of the bottom end of the sling 5, so that the lifting equipment can lift the installation beam 1. When the pier to be installed is reached, the operator on the pier controls the lifting equipment through the wireless remote control device to move the sling 4 downward, so that the sling 5 drives the installation beam 1 to move toward the pier, and the installation frame 3 also moves with it, and the contact plate 65 contacts the top of the pier. As the installation beam 1 moves downward, the threaded sleeve 66 moves downward with it, and the threaded sleeve 66 is threadedly engaged with the screw rod 64, and the threaded sleeve 66 rotates at the bottom end of the installation beam 1. 66 drives the gear shaft 67 to rotate. Under the synchronous transmission of the pulley group 68, the two screws 64 located on the same contact plate 65 are kept horizontal. The gear shaft 67 is meshed with the gear 10. The electric push rod 62 controls the left and right movement of the connecting plate 63 to align the installation shaft 9 with the pier hole. The installation shaft 9 is rotated to enter the pier hole to prevent the pier hole from being uneven and unable to fully enter the pier hole. It is convenient for operators to grout and fix the pier hole. As the installation beam 1 moves downward, the contact plate 65 gradually contacts the connecting plate 63, and the elastic telescopic rod 61 connected between the mounting frame 3 and the electric push rod 62 is forced to shrink.

[0048] As the elastic telescopic rod 1 61 is forced to shrink, the auxiliary roller 75 and the rotating wheel 78 are at the bottom arc position of the mounting beam 1, and the elastic telescopic rod 4 79 inside the rotating wheel 78 is squeezed by the contact block 710 and the bottom of the mounting beam 1. As the mounting beam 1 moves downward, the connecting rod 4 77 rotates at the end of the connecting rod 3 76, driving the connecting rod 4 77 to drive the rotating wheel 78 to rotate toward the drainage hole 2 on the corresponding side, and the rack 1 711 and the gear 2 712 are meshed with each other, so that the connecting rod 2 77 4 is rotated in the direction close to the mounting shaft 9, so that the auxiliary roller 75 rolls on the arc surface of the mounting beam 1, and the connecting rod 2 74 drives the connecting rod 1 73 to rotate, so that the elastic telescopic rod 3 72 on the top of the mounting seat 71 is contracted. When the rotating wheel 78 moves to the drain hole 2, it enters the contact block 710 in the drain hole 2. Since it is no longer blocked by the bottom wall of the mounting beam 1, the contracted elastic telescopic rod 4 79 returns to its original state, so that the elastic telescopic rod 4 79 limits the connecting rod 4 77 on the inner side of the drain hole 2.

[0049] The auxiliary roller 75 rolls on the arc surface of the mounting beam 1, and the ratchet 81 coaxially connected to the auxiliary roller 75 rotates accordingly, and the ratchet 81 meshes with the rack 2 82. The piston 1 85 at the end of the rack 2 82 slides on the inner side of the slide frame 84 under the push of the rack 2 82, and the spring 83 is stretched by the force. The piston 1 85 pushes the waterproof coating in the pipeline to enter the interior of the storage box 87 through the one-way valve 86, and pushes the piston 2 88 to slide upward on the inside of the storage box 87, so that the spraying frame 89 on the top of the two groups of storage boxes 87 on the same side sprays the waterproof coating on the arc surface of the mounting beam 1. When the elastic limit of the spring 83 is reached, the spring 83 returns to its original state, driving rack two 82 and piston one 85 to move in the direction of returning to their original positions. Due to the unidirectional transmission property of the ratchet 81, during the resetting process of rack two 82, the ratchet 81 will not transmit the transmission to the auxiliary roller 75. As the auxiliary roller 75 rolls on the arc surface of the mounting beam 1, the ratchet 81 continues to mesh with the rack two 82 for transmission, so that the piston one 85 pushes the waterproof coating in the pipeline and pushes the piston two 88 to slide upward on the inside of the storage box 87. The two groups of storage boxes 87 on the same side push the waterproof coating located above the piston two 88 into the inside of the spray rack 89, and the coating is sprayed from the spray rack 89 to continuously spray the arc surface of the mounting beam 1 with waterproof coating.
