Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and in particular relates to a multi-directional movable trolley for prefabricated shear reinforcement of a box beam. Background Art

[0002] With the continuous improvement of construction standardization, precast box girders are widely used in bridge construction. When designing precast box girders, shear reinforcement reinforcement is incorporated to strengthen the connection with the bridge deck pavement, which requires pre-embedded shear reinforcement during the prefabrication stage. Manual positioning is often used for welding shear reinforcement in the top slabs of precast box girders. However, with the continuous advancement of construction technology, auxiliary equipment for welding shear reinforcement in the top slabs of precast box girders has developed rapidly, resulting in the emergence of various types of shear reinforcement welding auxiliary trolleys. For example, the patent CN215210566U discloses a prefabricated beam shear reinforcement installation trolley, which includes a track system, a travel system, a connecting rod, a material collection platform, a limiter, a positioning system, a tool box and a block. The track system is used to fix the ground and provide support and guidance for the travel system. The connecting rod is arranged between the travel system and the material collection platform for connection and fixation. The limiter, positioning system and tool box are all arranged on the material collection platform. The positioning system is arranged on a single side of the material collection platform, and its symmetrical surface is provided with the tool box. The limiter is arranged between the material collection platform and the travel system to adjust the position. The block is arranged on the travel system to correct deviation. The positioning system designed for the prefabricated beam shear reinforcement installation trolley disclosed in this patent can better position, assist workers in installing shear reinforcement, ensure the quality of shear reinforcement installation, and solve the technical problem that the shear reinforcement prefabricated beam surface cannot be constructed by mechanization. It is easy to operate and has strong practicality.

[0003] It is undeniable that the prefabricated beam shear reinforcement installation trolley disclosed in the patent can indeed achieve the above-mentioned effects, but it still has certain shortcomings: in the actual production process, the welding positions of the shear reinforcement on the top plates of prefabricated box beams of different sizes are different, which requires adjusting the position of the positioning system according to the actual situation. However, the walking system of this patent can only move the longitudinal beam, not the transverse beam, which limits its movement and makes it difficult to adjust the position of the positioning system. Although the upper hook, lower hook and baffle of the positioning system can move along the first supporting beam to realize the left and right position adjustment function, and then realize the left and right position adjustment of the positioning system, it has many parts and components, and also requires the use of external tools, which makes the left and right position adjustment of the positioning system somewhat troublesome.

[0032] Example

[0033] See attached Figure 1-5 , a multi-directional mobile trolley for prefabricated shear reinforcement of box beams

[0034] A multi-directional movable trolley for prefabricated shear reinforcement of a box beam, comprising:

[0035] The tire frame 10 includes two support frames 11 symmetrically spaced apart and a plurality of connecting beams 12 fixed between the two support frames 11 and distributed along the length direction of the support frames 11 (the two ends of the connecting beams 12 are vertically welded to the support frames 11 at corresponding positions); wherein the top of the connecting beam 12 is lower than the top of the support frame 11; a support foot 121 abutting the ground is welded to the bottom of the connecting beam 12; a steel support plate 111 is fixed to the inside of the support frame 11 along its length direction, and a plurality of positioning grooves 112 are evenly spaced on the steel support plate 111; a steel support beam 122 extending along the length direction of the support frame 11 is welded to the middle position of the top of the plurality of connecting beams 12;

[0036] A longitudinal movement mechanism 20 is arranged on the top of the tire frame 10 and can be guided to move longitudinally along the tire frame 10. The longitudinal movement mechanism 20 includes a longitudinal movement frame 21 and at least two longitudinal movement wheels 22 installed at each end of the bottom of the longitudinal movement frame 21 at intervals; a longitudinal movement limiting groove 221 is recessed in the middle of the circumferential surface of the longitudinal movement wheel 22; a longitudinal movement limiting plate 113 extending along the length direction of the support frame 11 is fixed to the outer side of the support frame 11, and a longitudinal movement limiting strip 114 is integrally formed on the longitudinal movement limiting plate 113 to cooperate with the longitudinal movement limiting groove 221 for guidance; when the longitudinal movement mechanism 20 moves along the tire frame 10, the circumferential surface of the longitudinal movement wheel 22 abuts against the top surface of the longitudinal movement limiting plate 113, and the longitudinal movement limiting strip 114 is limited in the longitudinal movement limiting groove 221;

[0037] A transverse movement mechanism 30 is provided on the longitudinal movement mechanism 20 and can be guided to move transversely along the longitudinal movement mechanism 20. The transverse movement mechanism 30 includes a welding platform 31 and at least two transverse movement wheels 32 installed at intervals on each side of the bottom of the welding platform 31; a tool box 311 is provided on the top of the welding platform 31; a transverse movement limit groove 321 is recessed in the middle of the circumferential surface of the transverse movement wheel 32; transverse movement rails 211 are fixed on both sides of the top of the longitudinal movement frame 21, and a transverse movement limit strip 212 is fixed on the top of the transverse movement rail 211 to guide and cooperate with the transverse movement limit groove 321; when the transverse movement mechanism 30 moves transversely along the longitudinal movement mechanism 20, the circumferential surface of the transverse movement wheel 32 abuts against the top surface of the transverse movement rail 211, and the transverse movement limit strip 212 is limited in the transverse movement limit groove 321;

[0038] Multiple positioning mechanisms 40 are fixed at intervals on one side of the transverse mechanism 30. The positioning mechanism 40 consists of two positioning bodies 41 arranged at intervals. The positioning body 41 includes a positioning plate 411 whose top is fixedly connected to the side of the welding platform 31 of the transverse mechanism 30 by bolts and is vertically arranged and parallel to the welding platform 31 of the transverse mechanism 30, and a positioning rod 412 vertically fixed at the bottom of the positioning plate 411 away from the transverse mechanism 30.

[0039] In this embodiment, a longitudinal stop block 115 is fixed to the outer side of each end of the support frame 11; when the longitudinal moving wheel 22 approaches the end of the support frame 11, the longitudinal stop block 115 blocks the longitudinal moving wheel 22 to prevent the longitudinal movement mechanism 20 from detaching from the end of the support frame 11; there is a transverse stop block 213 at the outer end of both sides of the longitudinal frame 21; when the transverse moving wheel 32 approaches the end of the welding platform 31 of the transverse mechanism 30, the transverse stop block 213 blocks the transverse moving wheel 32 to prevent the transverse mechanism 30 from detaching from the end of the longitudinal frame 21.

[0040] During use, the middle part of the prefabricated box girder steel mesh is placed on top of the steel support beam 122 and its two ends are clamped in the positioning groove 112 of the steel support plate 111 to fix the steel mesh. When shear reinforcement welding is performed, the longitudinal movement mechanism 20 is pushed or moved with the help of an external device, and the longitudinal movement wheels 22 of the longitudinal movement mechanism 20 roll along the length direction of the longitudinal movement limit plate 113, and then the entire longitudinal movement mechanism 20 and the transverse movement mechanism 30 on its top are longitudinally moved along the tire frame 10. When the designed position is to be moved, the longitudinal movement mechanism 20 is stopped and the transverse movement mechanism 30 is pushed or moved with the help of an external device, and the transverse movement wheels 32 of the transverse movement mechanism 30 roll along the length direction of the transverse track 211, and then the welding platform 31 is translated relative to the longitudinal movement mechanism 20. When the positioning mechanism 40 on the side of the welding platform 31 reaches the position of the shear reinforcement to be welded, the transverse movement mechanism 30 is stopped. A worker climbs onto the welding platform 31 and places the shear bar (shaped like an inverted "U") onto the positioning body 41. The positioning rods 412 at the bottom of the positioning body 41 support the shear bar. The worker then welds the shear bar to the steel mesh. This allows the positioning body 41 to be moved and positioned to the desired shear bar by moving the transverse mechanism 30. This makes it suitable for welding shear bars on the top plates of prefabricated box girders of varying sizes, and the operation is simple and convenient.

[0041] It should be noted that when the longitudinal movement mechanism 20 and the transverse movement mechanism 30 stop, the longitudinal movement mechanism 20 and the transverse movement mechanism 30 are fixed with the aid of external devices or tools to prevent the longitudinal movement wheels 22 and the transverse movement wheels 32 from rolling.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is apparent that many modifications and variations are possible in light of the foregoing teachings.
