Description
Technical Field
[0001] The utility model belongs to the technical field of crane trolleys, and particularly relates to an anti-overturning crane trolley. Background Art
[0002] The crane trolley is an important component of the existing double-girder crane. When in use, the crane trolley can move along the two main girders of the double-girder crane. During the movement of the crane trolley, due to the occurrence of rail gnawing or derailment, there is sometimes a risk of the crane trolley overturning. Therefore, the existing crane trolley needs to have the function of anti-overturning.
[0003] At present, when the existing crane trolley realizes the anti-overturning function, sometimes an anti-overturning device such as a hook plate is set to hook the main girder. When installing the anti-overturning device, one end of the hook plate needs to be connected to the crane trolley, and the other end of the hook plate needs to be located below the main girder. However, with this setting method, on the one hand, it will cause the anti-overturning device to be too large in size. On the other hand, since one end of the hook plate also needs to be located below the main girder, it is not convenient to determine the position of the hook plate, thus not facilitating installation. Therefore, there are still drawbacks and deficiencies in the prior art. Summary of the Utility Model
[0004] The purpose of the utility model is to provide an anti-overturning crane trolley to solve the problems raised in the above background art.
[0005] The technical solution adopted by the utility model to solve the above problems:
[0006] An anti-overturning crane trolley includes a crane trolley body with a trolley frame and capable of moving along two main girders. Fixed frames parallel to the main girders are installed on the top surfaces of the two main girders outside the trolley frame. The fixed frames are box structures with cavities, and a first rectangular through hole parallel to the fixed frame is opened on the top surface of each fixed frame. A number of groups of anti-overturning devices are installed between the trolley frame and each fixed frame. Each group of anti-overturning devices includes a horizontally arranged connecting plate. One end of each connecting plate is connected to the trolley frame, and the other end of the connecting plate is located above the fixed frame and is installed with a vertically distributed anti-overturning rod. The anti-overturning rods are respectively opposite to the positions of the first rectangular through holes, and the bottom ends of the anti-overturning rods all penetrate through the first rectangular through holes and are slidably connected to the fixed frames through the first rectangular through holes. After the bottom ends of the anti-overturning rods penetrate through the first rectangular through holes, anti-overturning plates slidably connected to the inside of the fixed frames are coaxially installed. The anti-overturning plates are all rectangular plates, and the widths of the anti-overturning plates are all smaller than the widths of the first rectangular through holes, and the lengths of the anti-overturning plates are all larger than the widths of the first rectangular through holes.
[0007] Furthermore, the anti-overturning rods all penetrate through the connecting plates, and limit plates parallel to the connecting plates are installed at the tops of the anti-overturning rods after passing through the connecting plates. The limit plates and the connecting plates are connected by a plurality of first connecting bolts evenly distributed circumferentially along the limit plates.
[0008] Furthermore, the anti-overturning plates and the anti-overturning rods are connected by a plurality of second connecting bolts.
[0009] Furthermore, vertical mounting plates are fixedly connected to one ends of the connecting plates close to the trolley frame, and the mounting plates and the trolley frame are connected by third connecting bolts.
[0010] Furthermore, a plurality of reinforcing rib plates are fixedly connected between the connecting plates and the mounting plates.
[0011] Furthermore, a plurality of mounting through holes are formed in the bottom surface of the fixing frame along the length direction of the fixing frame, and second rectangular through holes parallel to the fixing frame are formed on both sides of each fixing frame.
[0012] Adopting the above technical solution, the beneficial effects of the present utility model are as follows:
[0013] The present utility model installs the fixing frame on the top surface of the main beam, thereby facilitating the installation of the fixing frame; secondly, when installing the anti-overturning device, by opening the first rectangular through hole on the fixing frame, the position of the first rectangular through hole can be used as a reference to facilitate the determination of the position of the anti-overturning device, and since the fixing frame is located on the top surface of the main beam, the size of the anti-overturning device can also be shortened, thereby facilitating the installation of the anti-overturning device; finally, since the width of the anti-overturning plate is smaller than the width of the first rectangular through hole and the length of the anti-overturning plate is greater than the width of the first rectangular through hole, it is convenient to install the anti-overturning plate in the fixing frame.

Specific embodiments
[0021] To make the objectives, technical solutions and beneficial effects of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.
[0022] As Figures 1 to 6 shown, the present utility model provides an anti-overturning crane trolley, which includes a crane trolley body 4 with a trolley frame 41 and capable of moving along two main beams 1. Fixing frames 3 parallel to the main beams 1 are installed on the top surfaces of the two main beams 1 outside the trolley frame 41. Specifically, since the fixing frames 3 are located at the top surface positions of the main beams 1, it is convenient to install the fixing frames 3; the fixing frames 3 are box structures with cavities, and a first rectangular through hole 31 parallel to the fixing frames 3 is opened on the top surface of each fixing frame 3. A number of groups of anti-overturning devices 2 are installed between the trolley frame 41 and each fixing frame 3, so as to ensure the anti-overturning effect of the crane trolley; each group of anti-overturning devices 2 includes a horizontally arranged connecting plate 21. One end of each connecting plate 21 is connected to the trolley frame 41, and the other end of each connecting plate 21 is located above the fixing frame 3 and is provided with a vertically distributed anti-overturning rod 22. The anti-overturning rods 22 are respectively opposite to the positions of the first rectangular through holes 31. When installing the anti-overturning devices 2, the positions of the first rectangular through holes 31 can be used as a reference to facilitate the determination of the positions of the anti-overturning devices 2. And since the fixing frames 3 are located at the top surface positions of the main beams 1, the dimensions of the anti-overturning devices 2 can also be shortened, thus facilitating the installation of the anti-overturning devices 2; the bottom ends of the anti-overturning rods 22 all penetrate through the first rectangular through holes 31 and are slidably connected to the fixing frames 3 through the first rectangular through holes 31. After the bottom ends of the anti-overturning rods 22 penetrate through the first rectangular through holes 31, anti-overturning plates 23 slidably connected to the inside of the fixing frames 3 are coaxially installed. The anti-overturning plates 23 are all rectangular plates, and the widths of the anti-overturning plates 23 are all smaller than the widths of the first rectangular through holes 31, and the lengths of the anti-overturning plates 23 are all greater than the widths of the first rectangular through holes 31. When the length direction of the anti-overturning plates 23 is parallel to the length direction of the first rectangular through holes 31, the anti-overturning plates 23 can pass through the first rectangular through holes 31, thus facilitating the installation of the anti-overturning plates 23 inside the fixing frames 3.
[0023] Specifically, when installing the anti-overturning device 2, first install the anti-overturning plate 23 in the fixing frame 3, then rotate the anti-overturning rod 22 until the length direction of the anti-overturning plate 23 is perpendicular to the length direction of the first rectangular through hole 31 in the horizontal direction, then connect the anti-overturning rod 22 with the connecting plate 21, and finally connect the connecting plate 21 with the trolley frame 41, thus facilitating the installation of the anti-overturning device 2.
[0024] To facilitate the disassembly and assembly between the anti-overturning rod 22 and the connecting plate 21, therefore, as Figures 3 to 6 shown, the anti-overturning rods 22 all penetrate through the connecting plate 21, and limit plates 24 parallel to the connecting plate 21 are installed at the top ends of the anti-overturning rods 22 after passing through the connecting plate 21. The limit plates 24 and the connecting plate 21 are all connected by a plurality of first connecting bolts 25 evenly distributed circumferentially along the limit plates 24. Specifically, when connecting the anti-overturning rod 22 and the connecting plate 21, first make the limit plate 24 abut against the connecting plate 21. At this time, the anti-overturning plate 23 is located below the first rectangular through hole 31, and the screw end of the first connecting bolt 25 passes through the limit plate 24 and is threadedly connected with the connecting plate 21, and the head of the first connecting bolt 25 abuts tightly against the limit plate 24, so as to facilitate the disassembly and assembly between the anti-overturning rod 22 and the connecting plate 21.
[0025] To facilitate the disassembly and assembly between the anti-overturning plate 23 and the anti-overturning rod 22, therefore, as Figure 2 and Figure 6 shown, the anti-overturning plate 23 and the anti-overturning rod 22 are connected by a plurality of second connecting bolts 26. Specifically, when connecting the anti-overturning plate 23 and the anti-overturning rod 22, the screw end of the second connecting bolt 26 passes through the anti-overturning plate 23 and is threadedly connected with the anti-overturning rod 22, and the head of the second connecting bolt 26 abuts tightly against the anti-overturning plate 23, so as to facilitate the disassembly and assembly between the anti-overturning plate 23 and the anti-overturning rod 22.
[0026] The specific setting method for connecting the connecting plate 21 and the trolley frame 41 is as follows: as Figures 2 to 5 shown, vertical mounting plates 27 are fixedly connected to one end of the connecting plate 21 close to the trolley frame 41. The mounting plates 27 and the trolley frame 41 are connected by third connecting bolts 28. Specifically, when connecting the connecting plate 21 and the trolley frame 41, the screw end of the third connecting bolt 28 passes through the mounting plate 27 and is threadedly connected with the trolley frame 41, and the head of the third connecting bolt 28 abuts tightly against the mounting plate 27, so as to facilitate the disassembly and assembly of the connecting plate 21 on the trolley frame 41.
[0027] Furthermore, as Figures 2 to 5As shown, a number of reinforcing ribs 29 are fixedly connected between the connecting plate 21 and the mounting plate 27. The reinforcing ribs 29 can improve the connection strength between the connecting plate 21 and the mounting plate 27 to ensure the structural stability of the anti-overturning device 2.
[0028] The specific installation method of the fixing frame 3 on the main beam 1 is as follows: As Figure 1 、 Figure 3 And Figure 5 shown, a number of mounting through holes 32 are provided along the length direction of the fixing frame 3 on the bottom surface of the fixing frame 3, which facilitates the installation of the fixing frame 3 on the main beam 1 through connecting parts such as bolts; and second rectangular through holes 33 parallel to the fixing frame 3 are provided on both sides of each fixing frame 3, which facilitates the insertion of connecting parts such as bolts into the mounting through holes 32.
