Description

Technical Field

[0001] The invention relates to the technical field of lifting devices, and in particular to a bridge crane with telescopic suspension on both sides of a main beam. Background Art

[0002] A bridge crane is a type of bridge crane that runs on an elevated track, also known as an overhead crane. The bridge of a bridge crane runs longitudinally along the tracks laid on the elevated tracks on both sides, and the hoisting trolley runs horizontally along the tracks laid on the bridge, forming a rectangular working range, so that the space under the bridge can be fully utilized to lift materials without being hindered by ground equipment. This type of crane is widely used in indoor and outdoor warehouses, factories, docks and open-air storage yards.

[0003] However, the trolley of a traditional bridge crane can only operate in the area between two tracks, and the working range of the trolley hook is even smaller than the area between the tracks. This cannot meet the needs when it is necessary to move items under the track or outside the track. Summary of the invention

[0004] The purpose of the present invention is to provide a bridge crane with telescopic suspension on both sides of the main beam in order to solve the above-mentioned problems, so as to solve the problem that the traditional bridge crane trolley in the prior art can only operate in the area between the two tracks, and the working range of the trolley hook is smaller than the area between the tracks. When it is necessary to transport items under the track or outside the track, the demand cannot be met, and other technical problems. Among the many technical solutions provided by the present invention, the preferred technical solution is capable of driving the main beam to move horizontally in a direction perpendicular to the suspension track through a driving mechanism, thereby expanding the movement and working range of the lifting trolley, and can meet the transportation needs of items under and outside the suspension track, while facilitating the avoidance of obstacles, and helping to improve work efficiency and other technical effects, as described below.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The present invention provides a bridge crane with telescopic suspension on both sides of the main beam, comprising a connecting beam and a main beam, wherein the cross-sections of the connecting beam and the main beam are both in an "I"-shaped structure, a trolley traveling mechanism capable of moving on a suspension track is installed at both ends of the connecting beam, and a lifting trolley capable of moving on the main beam is arranged on the main beam;

[0007] The extension direction of the main beam and the connecting beam is perpendicular to the extension direction of the suspension track, and the main beam is located below the connecting beam. A driving mechanism is arranged between the main beam and the connecting beam. There are two driving mechanisms in total, and a connecting rod is connected between the two driving mechanisms. Second limit plates for limiting the driving mechanism are arranged at both ends of the bottom of the connecting beam, and first limit plates for limiting the lifting trolley are arranged at both ends of the bottom of the main beam;

[0008] The driving mechanism includes a top moving component for moving on the connecting beam and a bottom driving component for driving the main beam to move along its length direction.

The ear holes of the first ear plate and the second ear plate are coaxial, and a connecting pin is installed through them to achieve the connection between the top moving component and the bottom driving component.

[0009] The above-mentioned bridge crane with telescopic suspension on both sides of the main beam is adopted. The structures and distances of the trolley walking mechanism and the lifting trolley are all existing technologies and are not described in detail. When the device is used, the trolley walking mechanism moves on the suspension track, so that the lifting trolley moves along the extension direction of the suspension track; when the top moving component moves on the connecting beam, the bottom driving component moves with the top moving component, thereby driving the main beam to move horizontally in the direction perpendicular to the suspension track. When the top moving component contacts the second limiting plate, the main beam can continue to be driven to move horizontally in the direction perpendicular to the suspension track through the bottom driving component; the main beam can be driven to move horizontally in the direction perpendicular to the suspension track through the driving mechanism, thereby expanding the movement and working range of the lifting trolley, being able to meet the transportation needs of items below and outside the suspension track, and being able to avoid obstacles such as factory columns and equipment as needed, thereby improving the flexibility of use and work efficiency of the device.

[0010] Preferably, the top moving component and the bottom driving component have exactly the same structure and are symmetrically distributed about the axis of the connecting pin shaft. The top moving component includes a carrier frame, and the cross-section of the carrier frame is a "U"-shaped structure. The two inner walls of the carrier frame are respectively equipped with a driving wheel and a driven wheel through a rotating shaft. There are two driving wheels and two driven wheels respectively. The driving wheels and the driven wheels are distributed in the horizontal direction and correspond to each other. There is a gap between the driving wheel and the driven wheel for inserting and clamping the connecting beam. A power component for driving the two driving wheels to rotate is arranged on the outside of the carrier frame.

[0011] Preferably, the power assembly includes a reduction motor and a driven gear, the reduction motor is installed on the outer side of the carrier frame close to the driving wheel, the output end of the reduction motor extends into the interior of the carrier frame and is installed with a driving gear, there are two driven gears, which are respectively installed on the outer sides of the rotating shafts of the two driving wheels, the driving gear is located between the two driven gears and the driving gear is meshed with the two driven gears at the same time.

[0012] Preferably, a counter roller is installed between the two inner walls of the carrier frame via a rotating shaft, and the counter roller is located directly below the gap formed by the driving wheel and the driven wheel.

[0013] Preferably, two horizontally symmetrically distributed guide wheels are installed at both horizontal ends of the carrier frame.

[0014] Preferably, two buffer blocks are installed between the two inner walls of the bearing frame, the two buffer blocks are respectively close to the two horizontal ports of the bearing frame, and respectively correspond to the two second limit plates at the bottom end of the connecting beam.

[0015] The beneficial effect is that the driving mechanism can drive the main beam to move horizontally in a direction perpendicular to the suspension track, thereby expanding the movement and working range of the lifting trolley, meeting the transportation needs of items under and outside the suspension track, and facilitating avoidance of obstacles, which helps to improve work efficiency.

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0025] See also Figure 1-Figure 5 As shown, the present invention provides a bridge crane with telescopic suspension on both sides of the main beam, including a connecting beam 6 and a main beam 4, the cross-sections of the connecting beam 6 and the main beam 4 are both in an "I"-shaped structure, and a trolley traveling mechanism 2 that can move on a suspension track 1 is installed at both ends of the connecting beam 6. Preferably, the trolley traveling mechanism 2 is connected to the connecting beam 6 through a hinge shaft. Such an arrangement can make the wheels on the same side of the trolley traveling mechanism 2 evenly stressed, thereby improving the safety of the device. A lifting trolley 5 that can move on the main beam 4 is arranged on the main beam 4;

[0026] The extension direction of the main beam 4 and the connecting beam 6 is perpendicular to the extension direction of the suspension track 1, and the main beam 4 is located below the connecting beam 6. A driving mechanism 3 is arranged between the main beam 4 and the connecting beam 6. There are two driving mechanisms 3, and a connecting rod 7 is connected between the two driving mechanisms 3. The two driving mechanisms 3 are connected by the connecting rod 7, which can ensure the stability of the two driving mechanisms 3 and improve the safety of the device. The second limiting plates 601 for limiting the driving mechanism 3 are arranged at both ends of the bottom of the connecting beam 6, and the first limiting plates 401 for limiting the lifting trolley 5 are arranged at both ends of the bottom of the main beam 4;

[0027] The driving mechanism 3 includes a top moving component 301 for moving on the connecting beam 6 and a bottom driving component 304 for driving the main beam 4 to move along its length direction. A first ear plate 302 is installed on the bottom surface of the top moving component 301, and a second ear plate 305 is installed on the upper surface of the bottom driving component 304. The ear holes of the first ear plate 302 and the second ear plate 305 are coaxial, and a connecting pin 303 is installed through them to realize the connection between the top moving component 301 and the bottom driving component 304.

[0028] As an optional embodiment, the top moving component 301 and the bottom driving component 304 are completely identical in structure and are symmetrically distributed around the axis of the connecting pin shaft 303. The top moving component 301 includes a carrier frame 3012. The cross-section of the carrier frame 3012 is a "U"-shaped structure. The two inner walls of the carrier frame 3012 are respectively equipped with a driving wheel 3015 and a driven wheel 3014 through a rotating shaft. There are two driving wheels 3015 and two driven wheels 3014 respectively. The driving wheels 3015 and the driven wheels 3014 are distributed in the horizontal direction, and the driving wheels 3015 and the driven wheels 3014 correspond to each other. There is a gap between the driving wheels 3015 and the driven wheels 3014 for inserting and clamping the connecting beam 6. A power component 3011 that drives the two driving wheels 3015 to rotate is arranged on the outer side of the carrier frame 3012. The device works During operation, the power component 3011 drives the two driving wheels 3015 to rotate, so that the friction between the two driving wheels 3015 and the connecting beam 6 is utilized, and at the same time, the two driven wheels 3014 are cooperated to make the top moving component 301 move on the connecting beam 6; using the above principle, when installing the main beam 4 and the bottom driving component 304, the main beam 4 is inserted into the gap between the driving wheel 3015 and the driven wheel 3014, and the main beam 4 is clamped by the driving wheel 3015 and the driven wheel 3014 to realize the suspended installation of the main beam 4. When the power component 3011 drives the driving wheel 3015 to rotate, since the main beam 4 is suspended in the air, the friction between the driving wheel 3015 and the main beam 4 can be used to drive the main beam 4 to move between the driven wheel 3014 and the driving wheel 3015, thereby realizing the movement of the main beam 4.

[0029] The power assembly 3011 includes a reduction motor 30111 and a driven gear 30113. The reduction motor 30111 is installed on the outer side of the carrier frame 3012 near the driving wheel 3015. The output end of the reduction motor 30111 extends into the interior of the carrier frame 3012 and is installed with a driving gear 30112. There are two driven gears 30113, which are respectively installed on the outer sides of the rotating shafts of the two driving wheels 3015. The driving gear 30112 is located between the two driven gears 30113 and the driving gear 30112 is meshed with the two driven gears 30113 at the same time. With this arrangement, when the device is working, the reduction motor 30111 drives the driving gear 30112 to rotate, and the driving gear 30112 and the driven gear 30113 are meshed and transmitted, thereby driving the two driving wheels 3015 to rotate synchronously.

[0030] A reverse roller 3016 is installed between the two inner walls of the carrier frame 3012 through a rotating shaft. The reverse roller 3016 is located directly below the gap formed by the driving wheel 3015 and the driven wheel 3014. In this way, the connecting beam 6 or the main beam 4 is inserted into the gap between the driving wheel 3015 and the driven wheel 3014. The reverse roller 3016 can contact the connecting beam 6 or the main beam 4. The reverse roller 3016 can support the connecting beam 6 or the main beam 4 to prevent the main beam 4 from tilting during the movement of the lifting trolley 5, thereby ensuring the safety of the device.

[0031] Two horizontally symmetrically distributed guide wheels 3013 are installed at the two horizontal ends of the support frame 3012. In this way, when the connecting beam 6 or the main beam 4 is inserted into the gap between the driving wheel 3015 and the driven wheel 3014, the guide wheel 3013 contacts the main beam 4 or the connecting beam 6, and is guided by the guide wheel 3013, so that the top moving component 301 and the main beam 4 can move smoothly.

[0032] Two buffer blocks 3017 are installed between the two inner walls of the support frame 3012. The two buffer blocks 3017 are respectively close to the two horizontal ports of the support frame 3012, and respectively correspond to the two second limit plates 601 at the bottom end of the connecting beam 6. In this way, the buffer blocks 3017 can play a buffering role to prevent the top moving component 301 or the bottom driving component 304 from being damaged by collision.

[0033] By adopting the above structure, the structures and distances of the trolley walking mechanism 2 and the lifting trolley 5 are all prior arts and are not described in detail. When the device is used, the trolley walking mechanism 2 moves on the suspension track 1, so that the lifting trolley 5 moves along the extension direction of the suspension track 1; when the top moving component 301 moves on the connecting beam 6, the bottom driving component 304 moves with the top moving component 301, thereby driving the main beam 4 to move horizontally in a direction perpendicular to the suspension track 1. When the top moving component 301 contacts the second limiting plate 601, the main beam 4 can continue to be driven to move horizontally in a direction perpendicular to the suspension track 1 through the bottom driving component 304; the main beam 4 can be driven to move horizontally in a direction perpendicular to the suspension track 1 through the driving mechanism 3, thereby expanding the movement and working range of the lifting trolley 5, being able to meet the transportation needs of items below and outside the suspension track 1, and being able to avoid obstacles such as factory columns and equipment as needed, thereby improving the flexibility of use and work efficiency of the device.

[0034] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
