Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a single-beam mechanism that is easy to assemble. Background Art

[0002] A crane is a multi-action lifting machine capable of vertically lifting and horizontally transporting heavy objects within a certain range. It is also known as an overhead crane, overhead crane, or overhead crane. A gantry crane, also known as a gantry crane, is a variation of the bridge crane. It is primarily used for loading and unloading outdoor cargo yards, material yards, and bulk cargo. A modular crane is a type of crane. To minimize operational impact, a modular beam crane is a perfect choice when no supporting structures are permitted within a work area. This crane system requires a roof structure strong enough to safely support the crane's load. Multiple crossbeams are mounted on a fixed main beam, significantly improving production efficiency.

[0003] The existing patent document with publication number CN205932967U discloses a new crossbeam and main beam connection structure for single-beam cranes. By placing the ends of the main beam on the top of the crossbeam, the crossbeam supports both ends of the main beam and bears force evenly, so that the connection between the main beam and the crossbeam is not easily torn when the crane on the main beam hangs heavy objects. The main beam structure is more stable, eliminating safety hazards in production operations.

[0004] Although the new crossbeam and main beam connection structure used in the above-mentioned single-beam crane can solve the corresponding technical problems, its main beam connecting plate and crossbeam connecting plate are connected by bolts, which makes the crossbeam assembly operation more complicated, time-consuming and labor-intensive, thereby reducing the efficiency of the crossbeam assembly.

[0027] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] like Figures 1 to 4 As shown, a single-beam mechanism that is easy to assemble includes a single beam 100, a movable transverse trolley 200, a control mechanism 300 for controlling the transverse trolley 200 to move along the length direction of the single beam 100 and perform vertical lifting operations, a supporting mechanism 400 for supporting, a docking mechanism 500 for inserting and placing the lifting ring assembly of the monorail trolley, and a plug-in mechanism 600 for positioning the lifting ring assembly of the monorail trolley. The transverse trolley 200 is arranged at the bottom of the single beam 100, the control mechanism 300 is arranged at the top of the single beam 100, and the supporting mechanism 400 is arranged on the single beam 100. 00 is provided on both sides of the top, a docking mechanism 500 is provided on the top of the supporting mechanism 400, and a plug-in mechanism 600 is provided on the docking mechanism 500; the docking mechanism 500 includes a crossbeam 510 provided on the top of the supporting mechanism 400, and the interior of the crossbeam 510 is provided with a limiting assembly 520 adapted to the lifting ring assembly of the monorail trolley; the plug-in mechanism 600 includes a pin 610 that cooperates with the limiting assembly 520 for positioning the lifting ring assembly of the monorail trolley, and a positioning assembly 620 is provided on one side of the crossbeam 510 for limiting the horizontal movement of the pin 610.

[0030] Among them, the control mechanism 300 includes a support assembly 310 arranged on the top of the single beam 100, and an electric control system 320 electrically connected to the transverse trolley 200 is provided on the support assembly 310. The working state or parameters of the transverse trolley 200 can be adjusted through the electric control system 320 to achieve automatic operation effect. The electric control system 320 can be composed of a PLC control box and a controller installed inside the control box.

[0031] Among them, the support assembly 310 includes two support rods 311 fixedly connected to the top of the single beam 100 and arranged perpendicular to the single beam 100. Two symmetrical brackets 312 are fixedly connected between the two support rods 311. The electronic control system 320 is installed on the brackets 312. The support assembly 310 can provide a support foundation for the electronic control system 320.

[0032] Among them, the supporting mechanism 400 includes a lower support plate 410 fixedly connected to one side of the top of the single beam 100, the top of the lower support plate 410 is fixedly connected to the upper support plate 420, and the upper support plate 420 is fixedly connected to the bottom of the crossbeam 510. The contact area between the crossbeam 510 and the single beam 100 can be increased by the lower support plate 410 and the upper support plate 420, which helps to improve the firmness of the connection between the crossbeam 510 and the single beam 100. The bottom of the lower support plate 410 is fixedly connected to a reinforcement plate 430, and one side of the reinforcement plate 430 is fixedly connected to the single beam 100. The lower support plate 410 can be reinforced by the reinforcement plate 430, which helps to improve the supporting strength of the lower support plate 410.

[0033] Among them, the limiting component 520 includes a mouth plate 521 that is vertically fixed and passes through the interior of the crossbeam 510 and is used for inserting the lifting ring assembly of the monorail trolley. The interior of the crossbeam 510 and the mouth plate 521 are both horizontally fixed with a hollow column 522 that passes through it. One end of the pin 610 is inserted into the inner cavity of the lifting ring assembly of the monorail trolley through the hollow column 522 and passes through the outside of the hollow column 522. The lateral position of the lifting ring assembly of the monorail trolley can be limited by the limiting component 520, and the vertical position of the lifting ring assembly of the monorail trolley can be limited by the pin 610, thereby realizing the positioning operation of the lifting ring assembly of the monorail trolley.

[0034] Among them, the positioning component 620 includes a card plate 621 movably arranged on one side of the hollow column 522, and a card slot 611 adapted to the card plate 621 is opened at one end of the surface of the pin 610. The bottom of the card plate 621 is clamped in the inner cavity of the card slot 611. By using the card plate 621 and the card slot 611 in conjunction with each other, the horizontal movement of the pin 610 in the inner cavity of the hollow column 522 can be restricted, effectively preventing the pin 610 from loosening from the inner cavity of the hollow column 522 and causing a loose connection.

[0035] Among them, the positioning assembly 620 also includes a lug 622 fixedly connected to one side of the beam 510, and a movable column 623 is vertically movable through the lug 622, and a connecting plate 624 is fixedly connected between the bottom end of the movable column 623 and the top of the card plate 621. A spring 625 is sleeved on the surface of the movable column 623, and the two ends of the spring 625 are respectively fixedly connected to the lug 622 and the connecting plate 624. Through the coordinated use of the lug 622, the movable column 623, the connecting plate 624 and the spring 625, the card plate 621 and the beam 510 can be connected, and the elastic force of the spring 625 is used to make the card plate 621 stably stuck in the inner cavity of the card slot 611, effectively preventing the card plate 621 from accidentally detaching from the inner cavity of the card slot 611.

[0036] Among them, the card plate 621 is provided with an inclined surface on the side facing the hollow column 522. The inclined surface can be used to change the direction of force, so that when the pin 610 is inserted into the inner cavity of the hollow column 522 and passes through it, the pin 610 can apply pressure to the card plate 621 through the inclined surface, so that the card plate 621 moves toward the direction of the lug 622 by itself, so that when the lifting ring assembly of the monorail trolley is positioned, there is no need to operate the card plate 621, so that the effect of quick assembly is achieved.

[0037] The end of the latch 610 away from the slot 611 and the end of the movable column 623 away from the connecting plate 624 are respectively fixedly connected with a pull ring 630, which facilitates the removal and manipulation of the latch 610 and the movable column 623.

[0038] It also includes a connecting mechanism 700 provided at both ends of the crossbeam 510 and used in conjunction with the locking mechanism of the monorail trolley;

[0039] Among them, the connecting mechanism 700 includes a side beam 710 fixedly connected to the end of the cross beam 510, and the top of the side beam 710 is provided with an ear piece 720 used in conjunction with the locking mechanism of the monorail trolley, and the bottom of the side beam 710 is provided with a guide wheel 730 slidingly connected to the guide groove of the monorail trolley. The ear piece 720 and the corresponding guide wheel 730 are jointly installed on the side beam 710. By cooperating with the locking mechanism of the monorail trolley and 700, the single beam 100 can be locked on the monorail trolleys on both sides, which helps to eliminate the swing of the single beam 100 during the lifting process.

[0040] The working principle of the present invention is as follows: by inserting the lifting ring assembly of the monorail trolley into the inner cavity of the mouth plate 521, and then inserting the latch 610 into the inner cavity of the lifting ring assembly of the monorail trolley through the hollow column 522 and penetrating to the outside of the hollow column 522, when the latch 610 is inserted to a certain distance, the end of the latch 610 applies pressure to the inclined surface of the clamping plate 621, so that the clamping plate 621 is forced to move toward the direction of the lug 622, and the clamping plate 621 drives the connecting plate 624 and the movable column 623 to move synchronously, and the spring 625 is forced to contract. Until the latch 610 is inserted to the maximum limit; if the slot 611 is just aligned with the card plate 621, the elastic force of the spring 625 can be used to make the card plate 621 stuck in the inner cavity of the slot 611; if the slot 611 is not aligned with the card plate 621, the latch 610 is rotated at this time, and the latch 610 drives the slot 611 to rotate synchronously until the slot 611 is aligned with the card plate 621. The elastic force of the spring 625 can be used to make the card plate 621 stuck in the inner cavity of the slot 611, thereby completing the installation operation of the single beam 100.

[0041] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or they are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
