[0001] The utility model relates to the technical field of hanging basket construction, in particular to a driving mechanism for moving a hanging basket based on an H-shaped steel track beam. Background Art

[0002] Hanging basket construction, also known as construction hanging basket, is a major equipment for the segmented construction of prestressed concrete continuous beams, T-shaped steel structures and cantilever beams. It can move forward as a whole along the track, so it is widely used in bridge construction.

[0003] During the specific construction process, as the pouring of the phased concrete volume is completed, the hanging basket needs to be moved to the next construction location. Based on this usage requirement, we proposed a driving mechanism for the movement of the hanging basket based on the H-shaped steel track beam. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Reference Figure 1-4 A driving mechanism for moving a hanging basket based on an H-shaped steel track beam comprises an H-shaped steel track beam 1 arranged between a track pad beam and a track pressure beam. There are two H-shaped steel track beams 1 and they are arranged side by side on a horizontal plane. A front support is commonly arranged on the upper parts of the two H-shaped steel track beams 1. A horizontal pushing hydraulic jack 2 is arranged on the part between the two H-shaped steel track beams 1 and located on the rear side of the front support.

[0024] A push plate 3 is welded to the middle of the lower end of the front support, the output end of the push hydraulic jack 2 is fixedly connected to the lower end of the push plate 3 by bolts, and the fixed end of the push hydraulic jack 2 is fixedly installed with a push seat 4 by bolts, and mounting holes 5 are opened at both ends of the upper surface of the push seat 4. The upper end surface of the mounting hole 5 is flush with the upper surface of the push seat 4 and a linkage plate 7 is welded together.

[0025] The upper parts of the two H-shaped steel track beams 1 and the adjacent flange plate parts are provided with spaced pin holes 9, and the upper surfaces of the two ends of the linkage plate 7 corresponding to the pin holes 9 are provided with pin heads 8 matching the pin holes 9. The pin head 8 and the linkage plate 7 are an integrated structure. When the pin head 8 is aligned with the corresponding pin hole 9, along with the upward movement of the linkage plate 7, the pin head 8 extends into the pin hole 9 to achieve pin connection with the H-shaped steel track beam 1.

[0026] The outer annular surface of the upper end of the pin head 8 is rounded, so as to facilitate the smooth insertion of the pin head 8 into the corresponding pin hole 9.

[0027] A support seat 10 is welded to the lower part of the rear side of the push seat 4, and an electric push rod 11 is fixedly installed on the upper surface of the support seat 10. The rear side of the linkage plate 7 extends to above the output end of the electric push rod 11. The output end of the electric push rod 11 is vertically upward and fixedly connected to the lower surface of the linkage plate 7 by bolts.

[0028] Mounting plates 12 are welded at both ends of the lower part of the jacking seat 4, and auxiliary support wheels 13 are installed on the lower surface of the mounting plate 12. The auxiliary support wheels 13 are in contact with the upper surface of the lower flange plate of the corresponding H-shaped steel track beam 1. For the jacking hydraulic jack 2 in the extended state, when the pin head 8 is out of the pin hole 9, the jacking hydraulic jack 2 is controlled to contract. At this time, based on the friction force between the front support and the upper surface of the H-shaped steel track beam 1, the jacking seat 4 and the related structures will move toward the jacking plate 3. At this time, the auxiliary support wheels 13 can provide auxiliary support for the jacking seat 4.

[0029] In summary, when the entire driving mechanism is in use, when the hanging basket needs to be moved, the corresponding oil pump system is connected to the top push hydraulic jack 2, and the electric push rod 11 is connected to the external power supply based on its control switch, and the top push hydraulic jack 2 is first controlled to extend and retract so that the pin head 8 is aligned with the nearest pin hole 9. When the pin head 8 and the pin hole 9 are aligned in the initial state, it is not necessary to control the top push hydraulic jack 2 to extend and retract first;

[0030] For the pin head 8 aligned with the pin hole 9, the electric push rod 11 is controlled to extend so that the pin head 8 extends into the pin head 8, and at this time, the push hydraulic jack 2 is extended. With the extension of the push hydraulic jack 2, the push seat 4, the linkage column 6, the linkage plate 7, and the pin head 8 are in a static fixed state relative to the H-shaped steel track beam 1, so that the push plate 3 and the front support are in a moving state relative to the H-shaped steel track beam 1, thereby realizing the movement of the front support and the entire hanging basket to which the front support belongs;

[0031] When the jacking hydraulic jack 2 is fully extended but the hanging basket has not reached the specified position, the electric push rod 11 is controlled to retract to make the pin head 8 disengage from the pin hole 9, and then the jacking hydraulic jack 2 is controlled to retract. At this time, the jacking seat 4, the linkage column 6, and the linkage plate 7 will move toward the jacking plate 3. When the jacking hydraulic jack 2 tends to be completely retracted and the pin head 8 is aligned with the pin hole 9, the above steps can be repeated to move the hanging basket again. Combined with the controllable telescopic stroke of the jacking hydraulic jack 2, it can be ensured that the entire hanging basket is driven to the target.

[0032] Therefore, the structure of the entire driving mechanism is simple and is located between the two H-shaped steel rail beams 1, without occupying additional space on the beam platform where the hanging basket is located. Therefore, when the hanging basket is not moved, there is no need to dismantle the driving mechanism separately. It is only necessary to disconnect the external power supply required by the electric push rod 11 and the oil pump system required by the top push hydraulic jack 2. Therefore, the phenomenon of multiple disassembly and assembly of the driving structure during the entire hanging basket construction process is avoided. In the process of moving the hanging basket through the driving mechanism, it is only necessary to observe the position of the pin head 8 relative to the pin hole 9, and the telescopic coordination of the top push hydraulic jack 2 and the electric push rod 11 can be completed. The operation is simple and convenient, which is conducive to its popularization and use in the process of hanging basket construction.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
