[0034] The track connecting device is used to connect the tracks between two adjacent transport vehicles. In this embodiment, the track connecting device is used to connect the first track 11 and the second track 21 .

[0035] Combine the following Figures 2 to 8 , the specific structure and principle of the track connection device provided by the embodiment of the present invention are described in detail. Figure 2 A schematic structural diagram of a track connecting beam of a track connecting device provided in an embodiment of the present invention; Figure 3 A structural schematic diagram of a connection state of a track connection device provided in an embodiment of the present invention; Figure 4 for Figure 3 A partial enlarged view of middle A; Figure 5 A schematic structural diagram of a first mounting block in a track connection device provided in an embodiment of the present invention; Figure 6 A schematic structural diagram of a track connection device in a retracted state provided by an embodiment of the present invention; Figure 7 for Figure 6 A partial enlarged view of B in the middle; Figure 8 for Figure 6 A partial enlarged view of C in the middle.

[0036] like Figure 2 and Figure 3As shown, the track connecting device includes a track connecting beam 31 and a locking assembly 34; the first end of the track connecting beam 31 is rotatably mounted on the first transport vehicle 1, and the locking assembly 34 is mounted on the first transport vehicle 1; the second end of the track connecting beam 31 is detachably connected to the second transport vehicle 2, so that the track connecting beam 31 is flush with the first track 11 on the first transport vehicle 1 and the second track 21 on the second transport vehicle 2, respectively; when the second end of the track connecting beam 31 is detached from the second transport vehicle 2, the first end of the track connecting beam 31 can be horizontally rotated relative to the first transport vehicle 1, so that the second end of the track connecting beam 31 is connected to the locking assembly 34.

[0037] The shape of the track connecting beam 31 can be the same as that of the first track 11, so that the guide vehicle can smoothly pass through the track connecting beam 31 and move to the second track 21. Figure 2 An anti-slip baffle 4 can be welded on one side of the track connecting beam 31 to prevent the guide trolley from derailing during operation.

[0038] The first end of the track connecting beam 31 is rotatably mounted on the first transport vehicle 1, that is, the first end of the track connecting beam 31 is not only mounted on the first transport vehicle 1, but also the track connecting beam 31 can be horizontally rotated around the first end of the track connecting beam 31. The first end of the track connecting beam 31 is rotatably mounted on the first transport vehicle 1, which can be achieved by providing a corresponding rotating shaft and an axial hole, that is, a rotating shaft can be provided at the first end of the track connecting beam 31, and an axial hole can be provided at a corresponding position on the first transport vehicle 1; or an axial hole can be provided at the first end of the track connecting beam 31, and a rotating shaft can be provided on the first transport vehicle 1.

[0039] The second end of the track connecting beam 31 can be connected to the second transport vehicle 2, and can also be connected to the locking assembly 34, see Figure 3 When the second end of the track connecting beam 31 is connected to the second track 21, the first track 11, the track connecting beam 31 and the second track 21 are flush, and the second end of the track connecting beam 31 can be detachably connected to the second track 21 by means of screw connection, pin connection, etc.

[0040] When it is necessary to store the track connecting beam 31, refer to Figure 6 , separate the second end of the track connecting beam 31 from the second track 21, that is, remove the second end of the track connecting beam 31 from the second transport vehicle 2; then horizontally rotate the track connecting beam 31 with the first end of the track connecting beam 31 as the center, so that the second end of the track connecting beam 31 is connected to the locking assembly 34.

[0041] The locking assembly 34 is installed on the first transport vehicle 1. The locking assembly 34 can be welded to the bottom end of the first rail 11. A mounting platform can also be set on the column of the first transport vehicle 1 to fix the locking assembly 34 on the mounting platform. The track connecting beam 31 can be locked to one side of the first rail 11 by the locking assembly 34 to prevent the track connecting beam 31 from moving and causing a safety accident; when the track connecting beam 31 needs to be connected to the second transport vehicle 2, the locking assembly 34 unlocks the track connecting beam 31, so that the track connecting beam 31 can rotate around its first end to its second end facing the second transport vehicle 2.

[0042] The first end of the track connecting beam 31 is rotatably installed on the first transport vehicle 1, and a locking assembly 34 is provided on the first transport vehicle 1. Regardless of whether the second end of the track connecting beam 31 is connected to the second rail 21, the track connecting beam 31 is located on the long rail transport vehicle set, and the installation and disassembly of the track connecting device can be achieved without the cooperation of a crane, which not only has high work efficiency but also has low safety risks.

[0043] On the basis of the above embodiment, a rotating shaft hole extending vertically is provided on the first transport vehicle 1, and a rotating shaft 15 is provided at the first end of the track connecting beam 31. The rotating shaft 15 is rotatably installed in the rotating shaft hole.

[0044] Reference Figure 3 A rotating shaft hole extending vertically is arranged on the first transport vehicle 1, and a rotating shaft 15 is arranged at the first end of the track connecting beam 31, and the rotating shaft 15 and the shaft hole are both circular, so that the friction is small when the track connecting beam 31 is horizontally rotated, and the operation is convenient; and the structure is simple and easy to install.

[0045] Based on the above embodiments, Figure 3 and Figure 4 The track connection device also includes a first mounting seat 12 , the top end of the first mounting seat 12 is fixedly connected to the first end of the track connection beam 31 , and the bottom end of the first mounting seat 12 is provided with a rotating shaft 15 .

[0046] The top end of the first mounting seat 12 is fixedly connected to the first end of the track connecting beam 31, and there are various connection methods. For example, the top end of the first mounting seat 12 is connected to the first end of the track connecting beam 31 through a round pin; for another example, the top end of the first mounting seat 12 is connected to the first end of the track connecting beam 31 through a screw, etc.

[0047] Reference Figure 3 , Figure 4 The rotating shaft 15 is arranged at the bottom end of the first mounting seat 12. Correspondingly, a rotating shaft hole matching therewith is arranged on the first transport vehicle 1. By setting the rotating shaft 15 and the rotating shaft hole, the first mounting seat 12 can be rotatably installed on the first transport vehicle 1, which is not only convenient for processing but also convenient for installation and simple for operation.

[0048] In some embodiments, reference Figure 2 , a first end of the track connecting beam 31 is provided with a first mounting opening 321, and coaxial second mounting holes 322 are provided on the side walls on both sides of the first mounting opening 321; Figure 5 The top of the first mounting seat 12 is provided with a first mounting block 13, and the first mounting block 13 is provided with a first mounting hole 131; the first mounting block 13 is accommodated in the first mounting opening 321, and then refer to Figure 4 A first fixing pin 132 is inserted into the first mounting hole 131 and the second mounting hole 322 .

[0049] Reference Figures 2 to 5 The first mounting opening 321 is located at the end of the first end of the track connecting beam 31, and the first mounting opening 321 is connected to the first mounting seat 12; illustratively, the first mounting opening 321 can be formed by cutting at the first end of the track connecting beam 31, or the first mounting opening 321 can be formed when the track connecting beam 31 is cast.

[0050] The second mounting holes 322 are located on the side walls of the first mounting opening 321. The second mounting holes 322 may have various shapes. Figure 2 The second mounting hole 322 is a circular hole. For another example, the second mounting hole 322 can also be a rectangular hole, a triangular hole, etc.

[0051] The first mounting block 13 is used to connect with the first end of the track connecting beam 31, and includes: a first connecting portion and a second connecting portion located below the first connecting portion, wherein the first connecting portion is provided with a first connecting hole 131, and the second connecting portion is used to connect with the first mounting seat 12. The first connecting portion is accommodated in the first mounting opening 321, and the shape of the first connecting portion should correspond to the first mounting opening 321.

[0052] The first mounting hole 131 is located in the middle of the first mounting block 13 , and the shape and size of the first mounting hole 131 are respectively the same as those of the second mounting hole 322 .

[0053] like Figure 3 and Figure 4 As shown, the first connection portion of the first mounting block 13 is accommodated in the first mounting opening 321 , and the first fixing pin 132 is inserted into the first mounting hole 131 and the second mounting hole 322 , so the connection method is simple and reliable.

[0054] In some embodiments, reference Figure 4 The first mounting seat 12 is also provided with a first locking hole, and the first transport vehicle 1 is provided with a second locking hole; when the second end of the track connecting beam 31 is connected to the locking assembly 34, a locking pin 14 is inserted into the first locking hole and the second locking hole. In other words, locking is performed at both ends of the track connecting beam 31, thereby improving the reliability of locking.

[0055] The first locking hole can be one, two, three, etc. The first locking hole and the second locking hole are the same in shape, size and number, and the positions of the first locking hole and the second locking hole correspond to each other, that is, the same number of second locking holes as the first locking holes are arranged at the corresponding positions on the first transport vehicle 1, as many first locking holes as the first mounting seat 12 is arranged; Figure 3 and Figure 4 When the second end of the track connecting beam 31 is connected to the locking assembly 34, a circular first locking hole is provided on the first mounting seat 12, and a similar second locking hole is provided on the first transport vehicle 1. A locking pin 14 is also provided between the first locking hole and the second locking hole to doubly fix the track connecting beam 31, so that the track connecting beam 31 is more stably connected to the first transport vehicle 1.

[0056] The locking pin 14 can not only be set when the second end 33 of the track beam connecting beam is connected to the locking assembly 34, but also when the second end of the track connecting beam 31 is connected to the second track 21, the locking pin 14 can be used for secondary tightening between the first mounting seat 12 and the first transport vehicle 1 to improve the reliability of the connection.

[0057] In some embodiments, the locking assembly 34 includes a support platform 35 , and a receiving groove is formed between the support platform 35 and the side wall of the first track 11 ; the second end of the track connecting beam 31 is received in the receiving groove to limit the movement of the track connecting beam 31 relative to the first track 11 .

[0058] Reference Figure 6 and Figure 7 The support platform 35 can be a block structure, the top of which is recessed downward to form a groove; or, the support platform 35 includes a flat plate and a support baffle plate arranged on the flat plate, so that a receiving groove is formed between the support platform 35 and the side wall of the first track 11, and the width of the receiving groove is greater than the width of the second end of the track connecting beam 31, so that after the second end of the track connecting beam 31 is separated from the second transport vehicle 2, the second end of the track connecting beam 31 can be easily accommodated in the receiving groove, thereby locking the track connecting beam and preventing the track connecting beam from moving relative to the first transport vehicle.

[0059] By providing a support platform 35 and forming a receiving groove between the support platform 35 and the first track 11 to accommodate the second end of the track connecting beam 31, the track connecting beam 31 is restricted from moving relative to the first transport vehicle 1, so that the track connecting beam 31 can be stably connected to the first transport vehicle 1, and the track connecting beam 31 does not need to be disassembled from the first transport vehicle 1, thereby improving work efficiency. Moreover, the locking assembly is simple in structure, convenient for installation and operation, and conducive to reducing costs.

[0060] On the basis of the above embodiment, the locking assembly 34 also includes a cam 36 and a rotating handle 37 connected to the cam 36, the cam 36 includes a supporting protrusion 361 and an avoidance portion 362; an opening is provided on the support platform 35, and the rotating handle 37 can drive the cam 36 to rotate until the avoidance portion 362 is accommodated in the opening, so that the second end of the track connecting beam 31 contacts the support platform 35; or, the rotating handle 37 can drive the cam 36 to rotate until the supporting protrusion 361 extends out of the opening, so that there is a gap between the second end of the track connecting beam 31 and the support platform 35.

[0061] Reference Figure 6 and Figure 7 The cam 36 is located below the support platform 35. The center of the cam 36 is connected to the rotating handle 37 through a rotating shaft. The support platform 35 is provided with an opening that can accommodate the cam 36. One end of the cam 36 is a supporting protrusion 361, and the other end of the cam 36 is an avoidance portion 362. The rotating handle 37 is fixed to the other side of the first track 11 away from the support platform 35. Rotating the rotating handle 37 can drive the cam 36 to rotate.

[0062] When the locking assembly 34 is connected to the second end of the track connecting beam 31, the rotating handle 37 is rotated so that the avoidance portion 362 is accommodated in the opening, so that the second end of the track connecting beam 31 contacts the support platform 35; when the locking assembly 34 needs to be separated from the second end of the track connecting beam 31, the rotating handle 37 is rotated so that the supporting protrusion 361 is accommodated in the opening, so that a gap is generated between the second end of the track connecting beam 31 and the support platform 35. Only by rotating the rotating handle 37, the contact or separation between the second end of the track connecting beam 31 and the support platform 35 can be controlled. The operation is simple and convenient. A cam stopper can also be provided under the cam 36 so that the cam 36 can be stably accommodated in the opening without swinging.

[0063] A cam 36 is provided and the rotation of the cam 36 is controlled by rotating the handle 37, so as to control the second end of the track connecting beam 31 to contact or disengage with the support platform 35. Not only is the structure simple and the operation is convenient, but also the present embodiment does not impose strict requirements on the manufacturing accuracy of the cam 36, which is conducive to reducing costs.

[0064] In some embodiments, reference Figure 4 The first end of the track connecting beam 31 is hinged with a support block 323, and the support block 323 is provided with a support groove 324; when there is a gap between the second end of the track connecting beam 31 and the support platform 35, the support block 323 rotates upward to abut against the track connecting beam 31; when the track connecting beam 31 is flush with the first track 11 and the second track 21, the support block 323 rotates downward to an avoidance position.

[0065] One end of the support block 323 is hinged to the first end of the track connecting beam 31, that is, the support block 323 can rotate up and down along the first end of the track connecting beam 31; the other end of the support block 323 is provided with a support groove 324, and the opening shape of the support groove 324 is the same as the cross-section of the track connecting beam 31, so as to increase the contact area between the support groove 324 and the track connecting beam 31, thereby improving the reliability of abutment.

[0066] When there is a gap between the second end of the track connecting beam 31 and the support platform 35, the support block 323 is rotated upward to accommodate the track connecting beam 31 in the support groove 324, so that the support block 323 abuts against the track connecting beam 31; when the track connecting beam 31 is flush with the first track 11 and the second track 21, that is, when the track connecting device is installed in place; or when the track connecting device is completely disassembled, the support block 323 is rotated downward until it is not in contact with the track connecting beam 31. The setting of the support block 323 makes the track connecting beam 31 more stable during rotation and saves the physical strength of workers.
