For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0032] Please refer to Figures 1 to 6 , in which, Figure 1 is a schematic structural diagram of the crossbeam device for hoisting in the present invention; Figure 2 is a side view of the crossbeam device for hoisting in the present invention; Figure 3 is a schematic structural diagram of the hoisting plate in the present invention; Figure 4 is a schematic structural diagram of the front workbench in the present invention; Figure 5 is a schematic structural diagram of the rear workbench in the present invention (removing the lifting power device, main hook and guide wheel); Figure 6 is a side view of the rear workbench in the present invention (removing the lifting power device, main hook and guide wheel).

[0033] The present invention provides a crossbeam device for hoisting, which mainly includes a hoisting plate 2, a sliding power device 5 and a moving workbench installed on the hoisting plate 2. The moving workbench is slidably matched with the hoisting plate 2, and the sliding power device 5 is connected between the moving workbench and the hoisting plate 2, with one end connected to the hoisting plate 2 and the other end connected to the moving workbench. When the moving workbench moves, it can provide sliding power for the moving workbench. A suspension rod 9 for providing a hoisting position for the crane is provided in the middle of the hoisting plate 2, which can provide a hoisting position for the hook during crane hoisting. A secondary hook 7, a main hook 6 slidably matched with the moving workbench, and a lifting power device 14 respectively connecting the moving workbench and the main hook 6 are provided on the moving workbench. The lifting power device 14 and the main hook 6 are both installed on the moving workbench. One end of the lifting power device 14 is connected to the moving workbench, and the other end is connected to the main hook 6, which can provide lifting power for the main hook 6 to enable the main hook 6 to move up and down on the moving workbench.

[0034] Specifically, the secondary hook 7 of the crossbeam device for hoisting of the present invention is fixedly installed on the moving workbench and can move translationally relative to the hoisting plate 2 along with the moving workbench. The main hook 6 is installed on the moving workbench and is slidably matched with the moving workbench, and thus can move up and down on the moving workbench. During hoisting, the secondary hook 7 and the main hook 6 are almost at the same horizontal height (the height difference is less than 2 cm). The secondary hook 7 hooks the steel wire rope on the equipment for hoisting. When it is necessary to replace the steel wire rope, another steel wire rope on the equipment is hung on the main hook 6. The main hook 6 is lifted upward under the action of the lifting power device 14. The steel wire rope on the main hook 6 is tightened, while the steel wire rope on the secondary hook 7 is relaxed and can be manually detached from the secondary hook 7, thereby realizing the replacement of the steel wire rope. When horizontal displacement is required, the sliding power device 5 acts to drive the moving workbench to slide and achieve horizontal displacement. The crossbeam device for hoisting of the present invention can realize the replacement of the steel wire rope (realized by the lifting of the main hook 6) and precise displacement (realized by the sliding of the moving workbench) through its own actions (the lifting and lowering of the main hook 6, the sliding of the moving workbench) during hoisting, avoiding the cumbersome operation of the cooperation between the main and secondary hooks 7 of the crane, and having the characteristics of high precision and convenient operation.

[0035] Furthermore, in the present invention, a guiding device is provided on the moving workbench, which can provide guidance for the lifting and sliding of the main hook 6. Specifically, a hole is formed in the moving workbench, and the main hook 6 passes through the hole into the lower part of the moving workbench and moves up and down in a direction perpendicular to the hole. The guiding device includes a guiding frame 15 and guiding wheels 13. The guiding frame 15 is welded to the moving workbench and is located on the left and right sides of the hole (main hook 6). The guiding wheels 13 are installed on the guiding frame 15 and can rotate on the guiding frame 15. When the main hook 6 moves up and down, the guiding wheels 13 are in contact with the main hook 6, so that the sliding friction between the original hole and the main hook 6 can be changed into the rolling friction between the main hook 6 and the guiding wheels 13, which can provide guidance for the lifting of the main hook 6 while reducing the frictional resistance. It should be noted that the guiding wheels 13 are in contact with the main hook 6 on the left and right sides of the main hook 6 here, which means that the opening direction of the main hook 6 is defined as the front or the back, and the guiding wheels 13 are on the side of the opening. At this time, the resistance of the main hook 6 to move up and down can be reduced, and the guiding wheels 13 will not be damaged due to the sudden force on the main hook 6.

[0036] Furthermore, in the present invention, in order to reduce the self-weight, the moving workbench includes a front workbench 1, a connecting rod 3 and a rear workbench 4. The front workbench 1 is located at the front end of the lifting plate 2, the rear workbench 4 is located at the rear end of the lifting plate 2, and the connecting rod 3 is connected between the front workbench 1 and the rear workbench 4, which can ensure the synchronous movement of the front workbench 1 and the rear workbench 4.

[0037] Furthermore, in the present invention, a front auxiliary hook 7 and a front main hook 6 are provided on the front workbench 1, and a rear auxiliary hook 7 and a rear main hook 6 are provided on the rear workbench 4. The opening directions of the front auxiliary hook 7, the front main hook 6, the rear auxiliary hook 7 and the rear main hook 6 are the same, and the direction is the front or the back. The front auxiliary hook 7 and the rear auxiliary hook 7 are used together, and the front main hook 6 and the rear main hook 6 are used together, which can make the front and rear ends of the lifting plate 2 receive a vertically downward pulling force, while the middle suspension rod 9 receives a vertically upward pulling force from the traveling crane (crane), so that the force on the cross beam device for hoisting is balanced and will not overturn.

[0038] Furthermore, in the present invention, a guiding rod 8 is provided at the front end of the lifting plate 2, and a guiding hole 12 is provided on the front workbench 1. The guiding rod 8 is inserted into the guiding hole 12 and is in sliding fit with the guiding hole 12, which can not only realize the guiding function but also bear the weight. Preferably, there are two guiding rods 8, which are symmetrically distributed on the left and right sides of the lifting plate 2 and are respectively located at positions close to the left and right sides of the lifting plate 2. There are two guiding holes 12, which are symmetrically distributed on the left and right sides of the front workbench 1 and are respectively located at positions close to the left and right sides of the front workbench 1, corresponding to the guiding rods 8 one by one, which can disperse the load-bearing and make the force more balanced.

[0039] Correspondingly, in the present invention, a slide rail 10 is provided at the rear end of the hoisting plate 2, and both ends of the slide rail 10 in the length direction are connected to the hoisting plate 2. A slide groove 17 is provided on the rear workbench 4, and the slide rail 10 is located in the slide groove 17 and slides with the slide groove 17. That is, the entire rear workbench 4 is placed on the hoisting plate 2 and can slide along the slide rail 10. Under the connection of the connecting rod 3, the sliding directions of the front workbench 1 and the rear workbench 4 are consistent. The present invention adopts a combination of a guide rod 8 and a guide hole 12, supplemented by a slide rail 10 and a slide groove 17. When the guide rod 8 is slightly bent downward during use, its use function can still be guaranteed, thereby increasing the service life of the crossbeam device for lifting and hoisting, and improving safety.

[0040] In order to further improve the safety factor, in the present invention, a support platform 11 is also provided at the rear end of the lifting plate 2, and a support plate 16 is provided on the rear workbench 4. The support plate 16 is placed on the support platform 11, and a gap is provided between the support plate 16 and the support platform 11, which can ensure that the rear workbench 4 does not separate from the lifting plate 2 in an emergency situation where the slide rail 10 fails.

[0041] As a power source, in the present invention, the sliding power device 5 and the lifting power device 14 are both selected as hydraulic cylinders. Specifically, the sliding power device 5 is a hydraulic cylinder, and the extension direction of the hydraulic cylinder is consistent with the sliding direction of the mobile workbench; the cylinder body of the hydraulic cylinder is installed on the lifting plate 2 and is fixedly connected to the lifting plate 2, one end of the cylinder rod is connected to the cylinder body and the other end is fixedly connected to the mobile workbench, which can ensure that the mobile workbench (front workbench 1) is provided with thrust or pulling force along the sliding direction. The lifting power device 14 is a hydraulic cylinder, and the extension direction of the hydraulic cylinder is consistent with the lifting direction of the main hook 6; the cylinder body of the hydraulic cylinder is installed on the mobile workbench and is fixedly connected to the mobile workbench, one end of the cylinder rod is connected to the cylinder body (fixed connection) and the other end is hinged to the main hook 6, and the hinged end is facing away from the opening direction of the main hook 6, which can provide upward thrust for the main hook 6 without bearing radial force. Correspondingly, there are two main hooks 6, and there are two hydraulic cylinders in the lifting power device 14, which correspond one to one with the main hooks 6.

[0042] Furthermore, in an equivalent embodiment of the present invention, the power source can be replaced by a cylinder, or a mechanical structure driven by a motor that can convert rotational motion into linear motion, etc.

[0043] like Figures 1 to 6 As shown, the working process of the present invention is described in detail below:

[0044] Sling the crossbeam device for hoisting on the overhead crane, sling the wire ropes on the equipment on the two auxiliary hooks 7 of the crossbeam device for hoisting, and start hoisting. When precise horizontal displacement is required, the sliding power device 5 pushes the front workbench 1 and the rear workbench 4 to slide, achieving horizontal displacement. When it is necessary to change the wire ropes, sling the other wire ropes on the equipment on the two main hooks 6 of the crossbeam device for hoisting. The lifting power device 14 drives the main hook 6 to lift, the wire ropes on the main hook 6 are tightened, while the wire ropes on the auxiliary hook 7 are slackened and can be removed. Similarly, when changing from hoisting with the main hook 6 to hoisting with the auxiliary hook 7, hang the other wire ropes on the auxiliary hook 7, lower the main hook 6, the wire ropes on the auxiliary hook 7 are tightened, and the wire ropes on the main hook 6 are slackened and can be removed.

[0045] As is known by common technical knowledge, the present invention can be implemented by other embodiments that do not depart from its spirit or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
