Description

Technical Field

[0001] The utility model belongs to the technical field of truss crane limit position, in particular to a fixing mechanism of a truss crane and a crossbeam. Background Art

[0002] The truss is a supporting beam structure assembled from multiple rods through welding, riveting or bolting. It cooperates with the linear movement of the overhead crane structure to form a truss overhead crane structure used for lifting and transportation.

[0003] Truss cranes are widely used. Under the driving action, the crane moves along the beam through rollers. The current crane limit is mainly achieved by locking the rollers and auxiliary fixation of the external limit structure to meet the fixation requirements of the crane and the beam. However, the current auxiliary positioning structure is generally relatively complicated, resulting in high operating costs, inconvenient operation, and low practicality. To this end, we provide a fixing mechanism for a truss crane and a beam to solve the above problems. Utility Model Content

[0005] The utility model is a fixing mechanism for a truss crane and a crossbeam, comprising a crane body, a driving assembly for driving the crane body to move, a crossbeam supported by the driving assembly, and a clamping assembly for locking the crane body and the crossbeam; the crane body comprises a mounting plate, a winch fixed to the side surface of the mounting plate, a hoisting roller connected to the winch roller via a steel cable, a lifting plate fixed to the hoisting roller, and a claw fixed to the lower edge of the lifting plate; the driving assembly comprises a motor fixed to the side surface of the mounting plate, a gear fixed to the output shaft of the motor, a toothed part meshing with the gear, a roller fixed to the toothed part, and a bearing seat for movable positioning of the roller; a guide rail is fixed to the upper side surface of the crossbeam, and a locking strip is fixed to the lower side surface of the guide rail; the clamping assembly comprises a support plate fixed to the side edge of the mounting plate, a cylinder fixed to the side surface of the support plate, and a locking part fixed to the telescopic end of the cylinder.

[0006] The utility model is further configured that a guide block is fixed to the back edge of the lifting plate, the guide block is movably connected to a slide rail, the slide rail is fixed with a positioning plate, and the top of the positioning plate is fixed to the lower side of the mounting plate.

[0007] The utility model is further configured that the roller is movably connected to the bearing seat via a shaft, the bearing seat is fixed to the lower side of the mounting plate, and the roller is movable on the upper side of the slide rail.

[0008] The utility model is further configured that the locking strip is provided with slots at equal intervals, and the protrusions on the upper side of the locking piece match the slots of the locking strip.

[0009] The utility model is further configured that an ear seat is integrally extended from the outer edge end of the locking member, a guide rod is passed through the ear seat, and the guide rod is fixed to the lower side of the support plate.

Example

[0023] See also Figure 1-4 The utility model is a fixing mechanism for a truss crane and a crossbeam, comprising a crane body, a driving assembly for driving the crane body to move, a crossbeam 1 supported by the driving assembly, and a clamping assembly for locking the crane body and the crossbeam 1.

[0024] In the fixing mechanism of the truss crane and the crossbeam involved in the present application, the position of the crane body relative to the crossbeam 1 is fixed by adding a snap-fit ​​assembly that cooperates with the locking strip 3 fixed on the lower side of the crossbeam 1. The snap-fit ​​assembly has a simple structure and is easy to operate, and is suitable for multi-position fixation of the crane body.

[0025] The overhead crane body includes a mounting plate 9, a winch 12 fixed to the upper side of the mounting plate 9, a hoisting roller 17 connected to the winding roller of the winch 12 via a steel cable, a lifting plate 16 fixed to the hoisting roller 17, and a claw 14 fixed to the lower edge of the lifting plate 16. A guide block is fixed to the back edge of the lifting plate 16, and the guide block is movably connected to a slide rail 18. A positioning plate 15 is fixed to the slide rail 18, and the top of the positioning plate 15 is fixed to the lower side of the mounting plate 9.

[0026] The mounting plate 9 in the overhead crane body serves as the main connecting structure for the installation and fixation of various structures. The winch 12 realizes the lifting and lowering control of the hoisting roller 17 through the steel cable, so that the lifting plate 16 is lifted and lowered linearly along the direction of the positioning plate 15 to achieve the height adjustment of the supporting claw 14. During the lifting and lowering process of the lifting plate 16, the guide block structure fixed on the back thereof cooperates with the guide rail 2 to ensure the smooth lifting and lowering of the lifting plate 16.

[0027] The driving assembly includes a motor 10 fixed to the upper side of the mounting plate 9, a gear 11 fixed to the output shaft of the motor 10, a toothed member meshing with the gear 11, a roller fixed to the toothed member, and a bearing seat 13 for movable positioning of the roller, wherein the roller is movably connected to the bearing seat 13 via a shaft, wherein the bearing seat 13 is fixed to the lower side of the mounting plate 9, and the roller moves on the upper side of the slide rail 18.

[0028] The driving assembly is used to drive the crane body to move linearly along the direction of the beam 1, wherein when the motor 10 is started, its output shaft drives the gear 11 to rotate, and the gear meshing with the gear 11 drives the roller to rotate, and under the friction between the roller and the guide rail 2, the roller moves linearly along the guide rail 2, thereby realizing the linear drive of the crane body.

[0029] A guide rail 2 is fixed to the upper side of the crossbeam 1 , and a locking strip 3 is fixed to the lower side of the guide rail 2 .

[0030] The guide rail 2 structure fixed on the upper side of the crossbeam 1 is used to assist the linear movement of the roller, while the locking strip 3 fixed on the lower side of the guide rail 2 is used for auxiliary positioning of the locking assembly.

[0031] The clamping assembly includes a support plate 6 fixed to the upper side edge of the mounting plate 9, a cylinder 7 fixed to the upper side of the support plate 6, and a locking member 4 fixed to the telescopic end of the cylinder 7. The locking strip 3 is provided with notches at equal intervals, and the upper side protrusions of the locking member 4 cooperate with the notches of the locking strip 3. An ear seat 5 is integrally extended from the outer edge end of the locking member 4, and a guide rod 8 is passed through the ear seat 5, and the guide rod 8 is fixed to the lower side of the support plate 6.

[0032] The locking member 4 in the engaging assembly is separated from the locking strip 3 in the initial state. When the locking action is performed, the telescopic end of the cylinder 7 is controlled to contract, and the locking member 4 fixed thereto rises until the protruding end of the locking member 4 is fully matched with the notch of the locking strip 3, so that the locking member 4 cannot move along the direction of the beam 1, thereby achieving the fixation of the overhead crane body relative to the beam 1. During the up and down lifting process of the locking member 4, the guide rod 8 is used to balance the lifting and lowering movement of the locking member 4, thereby improving the movement stability of the locking member 4.
