Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated beam transportation, and particularly relates to a prefabricated beam installation auxiliary device. Background Art

[0002] Currently, many road construction projects require the construction of corresponding bridges, which has led to a sharp increase in the demand for bridges. Most bridges are constructed using precast box girders. Precast box girders are prefabricated at a separate site. After the substructure is completed, they are transported to the erection site using transport equipment and erected using a bridge crane or other lifting equipment. This accelerates project progress and reduces construction time. Different bridge spans require different bridge dimensions.

[0003] However, some highway or municipal bridges today are relatively low from the ground, but the terrain near the bridge is complex, the bridge plane curve radius is small, and it is an S-shaped curve. Therefore, when installing prefabricated box beams and prefabricated T beams, they cannot be erected by bridge erection machines. In order to solve the above problems, a steel guide combined with a double-machine lifting method is adopted during the construction process for installation, but it is not convenient to transfer the through-hole when installing the prefabricated beams.

[0046] Example:

[0047] This embodiment provides a precast beam installation auxiliary device for solving the technical problem of inconvenient hole-passing when installing precast beams using a steel guide system and a dual-machine lifting system. The precast beam installation auxiliary device includes a guide rail 1, a movable trolley 2, a support beam 3, and a fixing assembly 4, wherein:

[0048] The guide rail 1 is arranged along a first direction, which is the length direction of the guide rail 1. In a working state, the guide rail 1 is connected to two adjacent cap beams.

[0049] The mobile trolley 2 can be moved along the first direction and installed on the guide rail 1. Optionally, it also includes a rope, one end of which is bolted to the mobile trolley 2 and the other end is connected to the beam transport vehicle 9. In this way, when the mobile trolley 2 is pushed to one end of the guide rail 1 close to the cap beam to be connected, the beam transport vehicle 9 can pull the mobile trolley 2 back to its original position through the rope for the next use.

[0050] The supporting beam 3 is rotatably installed on the mobile trolley 2. The supporting beam 3 is used to place the precast beam 10. When the beam transport vehicle 9 transports the precast beam 10 to a position close to the guide rail 1, one end of the precast beam 10 is lifted by a crane and placed on the supporting beam 3. In this way, the beam transport vehicle 9 transports the precast beam 10 and continues to move in the direction close to the guide rail 1, thereby pushing the mobile trolley 2 connected to the supporting beam 3 to move synchronously on the guide rail 1 until one end of the precast beam 10 is moved to the end of the guide rail 1 close to the cap beam to be connected, thereby achieving the purpose of transferring the precast beam 10 through the hole.

[0051] The fixing assembly 4 is installed on the supporting beam 3, and the fixing assembly 4 is used to fix the prefabricated beam 10. In this way, through the setting of the fixing assembly 4, the probability of the prefabricated beam 10 falling from the supporting beam 3 is reduced. As for the rotatably installed supporting beam 3, when the beam transport vehicle 9 needs to turn slightly, the supporting beam 3 will rotate with the rotation of the beam transport vehicle 9, thereby reducing the probability of the fixing assembly 4 and the prefabricated beam 10 being damaged.

[0052] Through the above structure, when the prefabricated beam 10 is installed by using the steel guide and double-machine lifting method, the prefabricated beam 10 is first transported to the specified position by the beam transport vehicle 9, so that the beam transport vehicle 9 and the guide rail 1 are located in the same straight line, and then one end of the prefabricated beam 10 is lifted by the crane and then placed on the supporting beam 3 located on the mobile trolley 2, and then the prefabricated beam 10 is fixed on the supporting beam 3 by the fixing component 4 to prevent the prefabricated beam 10 from falling from the supporting beam 3, and then the beam transport vehicle 9 is driven to move in the direction close to the guide rail 1, thereby pushing the mobile trolley 2 to move on the guide rail 1, and after reaching the specified position, the beam transport vehicle 9 stops moving. , the thrust driving the moving trolley 2 to move disappears, so that the moving trolley 2 stops moving, and then the precast beam 10 can be lifted out from the beam transport vehicle 9 and the moving trolley 2 by the cooperation of the two cranes. As for the rotatably installed supporting beam 3, when the beam transport vehicle 9 needs to make a small turn, it will drive the supporting beam 3 on which the precast beam 10 is placed and the fixing assembly 4 installed on the supporting beam 3 to rotate synchronously on the moving trolley 2, reducing the probability of damage to the fixing assembly 4 and the precast beam 10. Therefore, through the precast beam installation auxiliary device provided by the utility model, it is easier to transfer the through-hole when installing the precast beam 10 in a way of steel guide and double-machine lifting.

[0053] An optional implementation of this embodiment is as follows: the mobile vehicle 2 includes a longitudinal beam 21, a load-bearing plate 22 and running wheels 23, wherein:

[0054] There are two longitudinal beams 21 , and both longitudinal beams 21 are arranged along the first direction.

[0055] The bearing plate 22 is installed on one side of the two longitudinal beams 21 .

[0056] There are multiple running wheels 23, and the multiple running wheels 23 are rotatably mounted on the two longitudinal beams 21, and the multiple running wheels 23 on the two longitudinal beams 21 are arranged in a one-to-one correspondence. Optionally, there are four running wheels 23, and the four running wheels 23 are respectively located at the four vertices of the same rectangle.

[0057] Through the above structure, the setting of the running wheels 23 enables the mobile trolley 2 to move on the guide rail 1, and the setting of the longitudinal beam 21 makes it easier to install the running wheels 23, while allowing the running wheels 23 on the same side to be located on the same straight line. The setting of the load-bearing plate 22 facilitates the installation of the supporting beam 3.

[0058] Optionally, a pneumatic brake 5 is also included, which is installed on the load-bearing plate 22. The pneumatic brake 5 is used to stop the running wheel 23. In this way, through the setting of the pneumatic brake 5, when the beam transport vehicle 9 stops moving, the pneumatic brake 5 is also used to stop the running wheel 23, thereby avoiding displacement of the mobile trolley 2 during the process of lifting the prefabricated beam 10.

[0059] An optional implementation of this embodiment is as follows: it also includes a rotating rod 6, and a circular hole adapted for the rotating rod is opened in the center of the load-bearing plate 22. One end of the rotating rod 6 is fixedly installed in the center of the supporting beam 3, and the other end is rotatably installed in the circular hole, that is, the axis of the rotating rod 6 is perpendicular to the horizontal plane where the load-bearing plate 22 is located. In this way, through the setting of the rotating rod 6, the supporting beam 3 is rotatably installed on the load-bearing plate 22, so that the supporting beam 3 can rotate on the load-bearing plate 22 along the axis of the rotating rod 6.

[0060] Optionally, a bearing is also included, which is installed between the circular hole and the rotating rod 6. In this way, the friction between the rotating rod 6 and the circular hole is reduced by the setting of the bearing, making it easier for the rotating rod 6 to rotate in the circular hole, thereby facilitating the rotation of the supporting beam 3 on the load-bearing plate 22.

[0061] An optional implementation of this embodiment is as follows: the fixing assembly 4 includes a positioning plate 41 and a support rod 42, wherein:

[0062] There are two positioning plates 41, both of which are installed on the supporting beam 3 and are spaced apart along the second direction. The first direction and the second direction are perpendicular to each other, that is, the second direction is the width direction of the guide rail 1. In the working state, the bottom end of the prefabricated beam 10 is clamped between the two positioning plates 41 to prevent the prefabricated beam 10 from being displaced on the supporting beam 3.

[0063] There are two support rods 42, and one end of the two support rods 42 is hinged to the two ends of the supporting beam 3 respectively. In the working state, the other ends of the two support rods 42 are respectively abutted against the chamfers of the wing plates of the prefabricated beam 10. In this way, through the setting of the two support rods 42, the upper end of the prefabricated beam 10 is pressed tightly between the two support rods 42, reducing the probability of the prefabricated beam 10 tilting during movement.

[0064] Optionally, the support rod 42 includes:

[0065] One end of the first rod 421 is hinged to the supporting beam 3 . Optionally, one end of the first rod 421 is hinged to one end of the supporting beam 3 via a bolt.

[0066] A threaded hole is provided at the other end of the first rod 421, and one end of the second rod 422 is screwed to the other end of the first rod 421. In this way, the screwed second rod 422 makes it easy to adjust the length of the second rod 422 extending from the first rod 421, that is, to adjust the length of the support rod 42, thereby facilitating adaptation to precast beams 10 of different sizes.

[0067] An optional implementation of this embodiment is as follows: it also includes a pad 7, which is used to fasten the prefabricated beam 10. In the working state, the pad 7 is installed between the positioning plate 41 and the prefabricated beam 10, clamping the prefabricated beam 10 between the two positioning plates, further reducing the probability of the prefabricated beam 10 tilting.

[0068] Optionally, the spacer 7 includes a first plate 71, a second plate 72, a tube 73 and a screw 74, wherein:

[0069] The first plate 71 is a rectangular plate.

[0070] The second plate 72 and the first plate 71 are arranged parallel to each other.

[0071] One end of the tube body 73 is fixedly mounted on the first plate 71 and is located at the center of the first plate 71 .

[0072] One end of the screw rod 74 is fixedly mounted on the second plate 72 , and the inner side wall of the tube body 73 is provided with an internal thread, and the other end of the screw rod 74 is screwed into the tube body 73 . In this way, by rotating the screw rod 74 , the length of the screw rod 74 extending out of the tube body 73 can be adjusted, that is, the distance between the first plate 71 and the second plate 72 can be adjusted to accommodate precast beams 10 of different sizes.

[0073] An optional implementation of this embodiment is as follows: it also includes warning lights 8, which are multiple and are installed at the front and rear ends of the mobile cart 2 respectively. The setting of the warning lights 8 makes it easy to observe the position of the mobile cart 2 on the guide rail 1.

It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model.
