[0045] Bench 5 Specific implementation manner

[0046] The following is a preferred embodiment, and the present utility model will be described more clearly and completely in conjunction with the accompanying drawings.

[0047] As Figures 1 - 4 shown, this embodiment provides a steel bar jacking device, which includes a support mechanism 2 and a jacking mechanism 1. The top of the support mechanism 2 has five receiving cavities arranged at intervals along the first horizontal direction. The receiving cavities can accommodate the steel bar 4 and limit the degree of freedom of movement of the steel bar 4 in the second horizontal direction L2 perpendicular to the first horizontal direction L1; the jacking mechanism 1 is connected to the support mechanism 2, and the jacking mechanism 1 is used to drive the support mechanism 2 to rise and fall; the steel bar jacking device can move along the second horizontal direction L2. By arranging five receiving cavities at intervals along the first horizontal direction L1 at the top of the support mechanism 2, the receiving cavities can accommodate the long steel bar 4. By arranging the jacking mechanism 1, when the steel bar jacking device moves along the second horizontal direction L2, the support mechanism 2 and the steel bar 4 placed on the support mechanism 2 can avoid some obstacles by rising or falling to deliver the steel bar 4 to the destination, so that the steel bar jacking device can smoothly transport the steel bar 4 under various working conditions, thereby replacing part of the work of manually transporting the steel bar 4 and improving the work efficiency at the construction site.

[0048] For example, as Figure 3 and Figure 4 shown, the obstacles at the construction site may be equipment placed on the ground. At this time, the support mechanism can be raised to a height higher than the obstacle to avoid the obstacle and move forward; the obstacles at the construction site may also be steel bars or stirrups placed on the bench. At this time, the support mechanism can be lowered to a height lower than the obstacle to avoid the obstacle and move forward.

[0049] Of course, in other embodiments, the number of receiving cavities can be determined according to the length of the steel bar and the actual needs. For shorter steel bars, it is only necessary to ensure that at least two receiving cavities can support the steel bar along the first horizontal direction on the support mechanism.

[0050] Specifically in this embodiment, as Figure 1 and Figure 2As shown, the steel bar jacking device further includes a guiding mechanism 3. The guiding mechanism 3 is symmetrically arranged on both sides of the supporting mechanism 2 along the second horizontal direction. The guiding mechanism 3 includes a connecting rod 31 and a first pulley 32. The first end of the connecting rod 31 is slidably connected to the supporting mechanism 2 in the vertical direction. The second end of the connecting rod 31 is connected to the first pulley 32, and the first pulley 32 can roll along the second horizontal direction. That is to say, the guiding mechanism 3 is arranged along the second horizontal direction and is symmetrically arranged on both sides of the supporting mechanism 2. By providing the guiding mechanism 3 that is slidably connected to the supporting mechanism 2 in the vertical direction, when the supporting mechanism 2 rises or falls, the guiding mechanism 3 can remain at the original height unchanged, that is, the first pulley 32 of the guiding mechanism 3 always remains at the same height. The first pulley 32 can cooperate with the track to guide the steel bar jacking device to move along the second horizontal direction, making the movement of the steel bar jacking device smoother. The specific connection method between the connecting rod 31 and the supporting mechanism 2 in the vertical direction is the prior art and will not be elaborated here.

[0051] Specifically in this embodiment, as Figure 3 and Figure 4 shown, the steel bar jacking device in this embodiment is used for the construction of precast bridge beam boxes. The track that cooperates with the first pulley 32 is the bench 5 for erecting beam box stirrups. In other embodiments, the appropriate track can also be found according to the actual situation of the construction site. Or in more embodiments, if there is no appropriate track at the construction site, the guiding mechanism 3 can also be not provided, which will not be elaborated here.

[0052] In this embodiment, the jacking mechanism 1 further includes moving wheels (not shown in the figure). The moving wheels are arranged at the bottom of the jacking mechanism 1, and the moving wheels can roll along the second horizontal direction. By arranging the moving wheels that move along the second horizontal direction at the bottom of the jacking mechanism 1, it is convenient for the steel bar jacking device to move forward.

[0053] Specifically in this embodiment, the jacking mechanism 1 further includes a driver. The moving wheels move along the second horizontal direction through the drive of the driver, and there is no need to manually push the steel bar jacking device forward. The driver in this embodiment is a hydraulic cylinder.

[0054] In this embodiment, the connection method between the jacking mechanism 1 and the supporting mechanism 2 is a detachable connection, and the connection method between the guiding mechanism 3 and the supporting mechanism 2 is also a detachable connection. By setting the jacking mechanism 1 and the supporting mechanism 2 as detachable connections, and the guiding mechanism 3 and the supporting mechanism 2 as detachable connections, it is convenient for the handling of the jacking equipment, and at the same time, it also reduces the burden of the steel bar jacking device when running without a track.

[0055] That is to say, the jacking mechanism has moving wheels and is detachably connected to the support mechanism. On the one hand, the jacking mechanism 1 and the support mechanism 2 can move together along the second horizontal direction L2, so that the jacking mechanism can adjust the support height of the support mechanism at different positions in the second horizontal direction L2 to avoid obstacles. On the other hand, the jacking mechanism 1 and the support mechanism 2 are detachably connected. The jacking mechanism can be connected to the support mechanism 2 when the jacking mechanism 1 needs to work, and when the support mechanism 2 does not need to adjust the height to avoid obstacles and can move forward, the support mechanism 2 can be detached from the jacking mechanism 1, and the jacking mechanism 1 does not need to move forward with the support mechanism 2.

[0056] In this embodiment, as Figure 1 and Figure 2 shown, the support mechanism 2 specifically includes a horizontal support member 21 and a vertical support member 22. The horizontal support member 21 extends along the first horizontal direction L1, and the accommodation cavity is arranged at the top of the vertical support member 22. The horizontal support member 21 is connected to the bottom of the vertical support member 22. By providing the horizontal support member 21 and the vertical support member 22, the vertical support member 22 is used to set the accommodation cavity, and the horizontal support member 21 is used to connect different vertical support members 22. Compared with connecting the horizontal support member 21 at the middle position of the vertical support member 22, it is more convenient to connect the horizontal support member 21 at the bottom end of the vertical support member 22. The vertical support member 22 can be arranged directly above the horizontal support member 21, and the horizontal support member 21 supports the vertical support member 22, and the structural strength after connection is higher.

[0057] Specifically in this embodiment, the jacking mechanism 1 is connected to the horizontal support member 21, but there is no fixed connection position between the jacking mechanism 1 and the horizontal support member 21. The jacking mechanism 1 can be connected to any position of the horizontal support member 21, and the specific connection position is determined according to the actual obstacle avoidance needs at the construction site, which will not be elaborated here.

[0058] At the same time, in this embodiment, the number of the jacking mechanisms 1 is one. In other embodiments, when the length of the support mechanism 2 is relatively long and the number of accommodation cavities is relatively large, the number of the jacking mechanisms 1 can be multiple to increase the support points of the support mechanism 2, which will not be elaborated here.

[0059] In this embodiment, the horizontal support member 21 and the vertical support member 22 are connected by corner brackets. Connecting the horizontal support member 21 and the vertical support member 22 by corner brackets ensures the connection strength of the support mechanism 2, and the corner brackets have integrally formed right angles, which can ensure that the horizontal support member 21 and the vertical support member 22 are perpendicular to each other without skew.

[0060] In this embodiment, a second pulley 221 is provided at the top of the support mechanism 2. The second pulley 221 can roll along the first horizontal direction. A groove is formed on the rolling surface of the second pulley 221, and the accommodating cavity is formed on the groove. That is to say, the top end of each vertical support member 22 is provided with a rotatable second pulley 221. The groove of the second pulley 221 serves as the accommodating cavity, and the rotating shaft of the second pulley 221 extends along the second horizontal direction.

[0061] In this embodiment, the distance between adjacent accommodating cavities is defined as D, and 1m ≤ D ≤ 2m. By setting the distance between adjacent accommodating cavities to D ≥ 1m, raw materials are saved. By setting the distance between adjacent accommodating cavities to D ≤ 2m, the steel bars 4 can be properly supported, preventing the steel bars 4 from bending and sagging.

[0062] Although the specific implementation manners of the present invention have been described above, those skilled in the art should understand that this is only for illustration purposes. The protection scope of the present invention is defined by the appended claims. Without departing from the principles and essence of the present invention, those skilled in the art can make various changes or modifications to these implementation manners, but these changes and modifications all fall within the protection scope of the present invention.
