Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Fig. 1 is a schematic structural diagram of a connection system according to a first embodiment of the present invention. As shown in fig. 1, the connection system 10 includes a first and a second rail crane (not shown) moving along a linear rail 11, and a connection mechanism 12 connected between the first and the second rail crane. Specifically, the first and second hangers are provided with the buffers 13, respectively. The connecting mechanism 12 comprises a first end and a second end which are oppositely arranged, the first end of the connecting mechanism 12 is fixed on the buffer 13 of the first track crane 2, and the second end of the connecting mechanism 12 is fixed on the buffer 13 of the second track crane.

The connecting mechanism 12 includes a plurality of connecting members, which may be connecting rods, detachably connected in sequence. Taking the first track crane as an example of failure, and the second track crane as an example of no failure, when the second track crane pulls the first track crane, the connecting mechanism 12 is in a straight line, so as to apply the pulling force of the second track crane to the first track crane; when the second track crane pushes the first track crane, the connecting mechanism 12 is still in a straight line, so that the pushing force of the second track crane is applied to the first track crane, that is, the connecting mechanism 12 has a push-pull function at the same time.

The specific structure of the connection mechanism 12 will be described below with reference to the embodiment. It should be understood that the connection system shown in fig. 1 is only one application scenario for the connection mechanism 12, and that the connection mechanism 12 may also be used in other scenarios to connect two devices or apparatuses or components and perform a push and/or pull function.

Fig. 2 is a schematic structural diagram of a connection mechanism according to an embodiment of the present invention. As shown in fig. 2, the connecting mechanism 12 includes a first connecting member 121, a second connecting member 122 and a third connecting member 123, and the first connecting member 121, the second connecting member 122 and the third connecting member 123 respectively include a first end and a second end which are oppositely disposed. The second end of the first connecting member 121 and the first end of the second connecting member 122 are hinged by a first pin 141. The second end of the second connecting member 122 is hinged to the first end of the third connecting member 123 by a second pin 142 and a third pin 143. The axes of the first pin 141, the second pin 142 and the third pin 143 are parallel to each other.

In use, the first end of the first connecting member 121 is fixed to the buffer 13 of the first gantry crane, and the second end of the third connecting member 123 is fixed to the buffer 13 of the second gantry crane. In this case, the first and

second connection members

121 and 123 may be implemented as bases fixed to the buffers 13 of the first and second rail hangers, respectively. In one embodiment, the first pin 141, the second pin 142, and the third pin 143 are detachable. That is, the first end of the second connecting member 122 and the second end of the first connecting member 121 are detachable, and the second end of the second connecting member 122 and the first end of the third connecting member 123 are detachable. In this way, the attachment mechanism 12 can be easily attached and detached.

Since the first connecting member 121, the second connecting member 122 and the third connecting member 123 are connected in sequence, the connecting mechanism 12 can perform a pulling function. Meanwhile, the axes of the first pin 141, the second pin 142 and the third pin 143 are parallel to each other, i.e., three hinge points on the second connecting member 122 form a deformable triangle. Based on the stability of the triangle, on one hand, the connection mechanism 12 is ensured to be in a straight line when being subjected to thrust, so that the pushing function is realized; on the other hand, the distance between the first connecting member 121 and the third connecting member 123 can be finely adjusted, so that the alignment deviation compensation of the connecting mechanism 12 along the direction x of the rail 11 is realized. For example, by remotely controlling the non-faulty trolley to stop at a predetermined distance from the faulty trolley, the predetermined distance is just the length of the coupling mechanism 12 when laid flat. However, due to inertia, the non-faulty trolley continues to move a small distance closer to the faulty trolley, in which case the small distance can be compensated for by a fine tuning function of the connection means 12 in the length direction to achieve a connection between the non-faulty trolley and the faulty trolley.

Fig. 3 is a schematic structural diagram of a first connecting member according to an embodiment of the present invention. Fig. 4 is a schematic structural diagram of a second connecting member according to an embodiment of the present invention. As shown in fig. 2 and 3, the second end of the first connecting member 121 is provided with a baffle 1211 and a first single lug 1212 positioned at a side of the baffle 1211 close to the second connecting member 122. As shown in fig. 2 and 4, the first end of the second connecting member 122 is provided with a first pair of ears 1224, the end surface 1225 of each of the first pair of ears 1224 is a plane, and the end surface 1225 and at least one side surface 1226 of each of the first pair of ears 1224 smoothly transition through an arc surface 1227. The first single ear 1212 and the first pair of ears 1224 are connected by a first pin 141.

Specifically, as shown in fig. 3, the first connecting member 121 is a first base, a first end of the first base is fixed on the bumper 13 of the first rail hanger, a baffle 1211 and a first single lug 1212 located at a side of the baffle 1211 close to the second connecting member 122 are disposed at a second end of the first base, and a first single hole 1213 is disposed on the first single lug 1212. The first end of the second connecting member 122 is provided with a first pair of ears 1224, the end surface 1225 of each of the first pair of ears 1224 is planar, and the end surface 1225 and at least one side surface 1226 of each of the first pair of ears 1224 are smoothly transitioned by an arcuate surface 1227. The first pair of double lugs 1224 is provided with a first auxiliary hole 1225, and the first single hole 1213 and the first auxiliary hole 1225 are connected by a first pin 141. By providing the stop 1211 and the end surface 1225, it is ensured that the pushing force applied by the first connecting member 121 to the second connecting member 122 is transmitted in a direction perpendicular to the first pin 1411, thereby ensuring that the connecting mechanism 12 is in a straight line during the pushing function.

Fig. 5 is a schematic structural diagram of a third connecting member according to an embodiment of the present invention. As shown in fig. 2, 4 and 5, the second end of the second connecting member 122 is provided with a second pair of two lugs 1221, the first end of the third connecting member 123 is provided with a second single lug 1231, and the opening dimension D of the second pair of two lugs 1221 is greater than the thickness of the second single lug 1231.

Specifically, referring first to fig. 4, the second end of the second connecting member 122 is provided with a second pair of lugs 1221, and the second pair of lugs 1221 are provided with a second pair of holes 1222 and a third pair of holes 1223. Referring to fig. 5, the first end of the third connecting member 123 is provided with a second single ear 1231, and the second single ear 1231 is provided with a second single hole 1232 and a third single hole 1233 penetrating the second single ear 1231 in the thickness direction. Referring to fig. 2, 4 and 5, the second auxiliary hole 1222 of the second connecting member 122 and the second single hole 1232 of the third connecting member 123 are connected by a second pin 142, and the third auxiliary hole 1223 of the second connecting member 122 and the third single hole 1233 of the third connecting member 123 are connected by a third pin 143. In one embodiment, the second single aperture 1232 and the second auxiliary aperture 1222 are both clearance fitted with the second pin 142, and the third single aperture 1233 and the third auxiliary aperture 1223 are both clearance fitted with the third pin 143. Thus, the disassembly and assembly can be facilitated.

The opening dimension of the second two ears 1221 is larger than the thickness of the second monaural 1231. In one embodiment, the opening dimension D of the second two ears 1221 is 4.5-5.5 mm greater than the thickness of the second single ear 1231. In this case, the second monaural element 1231 can slide between the second two ears 1221 along the axes of the second pin 142 and the third pin 143, so that the connecting mechanism 12 has the alignment deviation compensation in the second direction z. The second direction z may be a horizontal direction perpendicular to the rail 11 or a vertical direction perpendicular to the rail 11 according to the orientation of the connection mechanism 12 in practical application. Taking the second direction z as an example of a vertical direction perpendicular to the rail 11, according to the coupling mechanism provided in the present embodiment, when there is a deviation in the arrangement heights of the buffers 13 on the first and second track hangers, the coupling mechanism 12 itself can compensate for the deviation, thereby coupling the first and second track hangers.

In one embodiment, the diameter of the second pin 142 is larger than that of the third pin 143, i.e. the second end of the second connecting element 122 is hinged to the first end of the third connecting element 123 by two connecting rods with different thicknesses. Accordingly, the second end of the second connecting member 122 needs to be provided with the second subsidiary hole 1222 and the third subsidiary hole 1223 having different diameters. In this way, space on the second link 122 can be saved.

In one embodiment, as shown in FIG. 2, the attachment mechanism 12 further includes a fourth link 124. Fig. 6 is a schematic structural diagram of a fourth connecting member according to an embodiment of the present invention. As shown in fig. 6, the fourth connecting member 124 includes a first end and a second end that are opposite to each other, the first end of the fourth connecting member 124 and the second end of the third connecting member 123 are hinged by a fourth pin 144, and the fourth pin 144 is perpendicular to the first pin 141, the second pin 142 and the third pin 143.

Specifically, as shown in fig. 5, the second end of the third connecting element 123 is provided with a third double lug 1234, and the third double lug 1234 is provided with a fourth auxiliary hole 1235. The fourth auxiliary hole 1235 is perpendicular to the axes of the third auxiliary hole 1233 and the second auxiliary hole 1232. As shown in fig. 6, a first end of the fourth connecting member 124 is provided with a third single lug 1241, and the third single lug 1241 is provided with a fourth single hole 1242. The fourth auxiliary aperture 1235 and the fourth single aperture 1242 are connected by a fourth pin 144. Since the axes of the fourth auxiliary hole 1235 and the third auxiliary hole 1233 and the second auxiliary hole 1232 are perpendicular, that is, the fourth pin 144 is perpendicular to the first pin 141, the second pin 142 and the third pin 143. Therefore, when the connecting mechanism 12 is subjected to thrust, the connecting mechanism 12 can still be in a straight line, so that the connecting mechanism 12 realizes the push-pull function by utilizing more connecting rods, and the application range of the connecting rods is improved.

In one embodiment, the opening dimension d of the third pair of ears 1235 at the second end of the third connecting member 123 is greater than the thickness of the third single ear 1241 at the first end of the fourth connecting member 124. In one embodiment, the opening dimension D of the third pair of ears 1235 is 4.5-5.5 mm greater than the thickness of the third monaural 1241. In this case, the third monaural element 1241 can slide between the third pair of ears 1235 along the axis of the fourth pin 144, so that the connecting mechanism 12 has compensation for misalignment in the third direction y, which is perpendicular to the first direction x and the second direction z. Taking the third direction y as a horizontal direction perpendicular to the rail 11 as an example, when there is a horizontal deviation in the arrangement of the buffers 13 on the first and second gantry cranes, the coupling mechanism 12 itself can compensate for the deviation, thereby coupling the first and second gantry cranes. According to the connecting mechanism provided by the embodiment, the alignment deviation of the first track crane and the second track crane in three directions perpendicular to each other can be compensated.

In one embodiment, as shown in FIG. 2, the connection mechanism 12 is symmetrical about the fourth link 124. In this case, the connecting mechanism 12 further includes a fifth connecting member 125, a sixth connecting member 126 and a seventh connecting member 127, and each of the fifth connecting member 125, the sixth connecting member 126 and the seventh connecting member 127 includes a first end and a second end which are oppositely disposed. The second end of the fourth connecting element 124 is hinged to the first end of the fifth connecting element 125 through a fifth pin 145, the second end of the fifth connecting element 125 is hinged to the first end of the sixth connecting element 126 through a sixth pin 146, and the second end of the sixth connecting element 126 is hinged to the seventh connecting element 127 through a seventh pin 147. The structure of the fifth link 125 is the same as that of the third link 123, the structure of the sixth link 126 is the same as that of the second link 122, and the structure of the seventh link 127 is the same as that of the first link 121. For specific structures of the fifth connecting element 125, the sixth connecting element 126 and the seventh connecting element 127, reference may be made to the descriptions of the third connecting element 123, the second connecting element 122 and the first connecting element 121 in the foregoing embodiments, and details are not described here.

According to the connecting mechanism provided by the embodiment, the alignment error adjustment range in three directions perpendicular to each other is doubled, so that the application range of the connecting mechanism 12 is further improved.
