[0045] Figure 1 The schematic diagram of the structure of the crawler transfer system 10 provided in this embodiment is as follows: Figure 2 The schematic diagram of the structure of the crawler-type transfer equipment 100 provided in this embodiment when transferring the material 23 is shown in FIG. Figure 3 This is a circuit connection diagram of the crawler transfer equipment 100 provided in this embodiment. Figure 1-Figure 3 This embodiment provides a crawler-type transfer equipment 100 and also provides a crawler-type transfer system 10.

[0046] The crawler transfer system 10 includes a crawler transfer device 100 and a reclaimer 200. The crawler transfer device 100 transfers the material 23 at the stockpile 21 to the reclaimer 200, and forms a transfer stockpile 22 at the reclaimer 200. The reclaimer 200 transports the material 23 at the transfer stockpile 22 downstream, thereby completing the transfer of the material 23. Specifically, the reclaimer 200 includes a ground belt conveyor 211 and a stacker-reclaimer 212. The ground belt conveyor 211 is installed on the ground and is used to transport the material 23. The stacker-reclaimer 212 can move in a small range along the ground belt conveyor 211 to transfer the material 23 at the transfer stockpile 22 to the ground belt conveyor 211.

[0047] The crawler transfer equipment 100 includes a crawler reclaimer 111, a crawler telescopic stacker 117, and a plurality of crawler transfer bridge machines 112. The crawler reclaimer 111 is used to retrieve materials from a material pile 21. The plurality of crawler transfer bridge machines 112 are connected in sequence to form an intermediate conveyor line. The feeding end of the intermediate conveyor line is connected to the crawler reclaimer 111, and the discharging end of the intermediate conveyor line is connected to the crawler telescopic stacker 117 to transfer the material 23 retrieved by the crawler reclaimer 111 to the crawler telescopic stacker 117. Each device is a crawler structure, so that it can quickly circulate and be spliced ​​according to the specific position of the material pile 21 to form a transfer equipment, which improves the transfer. The transfer efficiency is improved, and the crawler reclaimer 111, the crawler telescopic stacker 117 and the multiple crawler transfer bridge machines 112 all have a circuit component 120, and the first active plug 125 of two adjacent circuit components 120 is plugged into the first socket 127, so that the crawler reclaimer 111, the crawler telescopic stacker 117 and the multiple crawler transfer bridge machines 112 are powered by series connection, meeting the position conversion requirements of the crawler reclaimer 111 and the increase or decrease requirements of the number of crawler transfer bridge machines 112, so that the power supply requirements of the multiple crawler transfer bridge machines 112 to exit and join at any time during the transfer process can be met.

[0048] It should be noted that, in the description of this embodiment, if two devices are mentioned to be "connected", it means that the conveyor belts 139 of the two devices can be connected to each other, and the material 23 conveyed on the conveyor belt 139 of one device can be conveyed to the conveyor belt 139 of the other device. In other words, the connection between the two devices does not mean that there is an interconnected structure between the two devices.

[0049] The crawler transfer device 100 provided in this embodiment is further described below:

[0050] Please continue to refer to Figure 1-Figure 3 In this embodiment, the crawler reclaimer 111, the crawler telescopic stacker 117 and the plurality of crawler transfer bridge machines 112 are all structures with crawlers and conveyor belts 139, which can drive the whole machine to transfer through the crawler, and convey the material 23 through the conveyor belt 139. At the same time, the crawler reclaimer 111, the crawler telescopic stacker 117 and the plurality of crawler transfer bridge machines 112 are spliced ​​together to form a conveying route for transferring the material 23. Moreover, since the crawler transfer equipment 100 is formed by splicing the crawler reclaimer 111, the crawler telescopic stacker 117 and the plurality of crawler transfer bridge machines 112, when there is a need to transfer materials 23 at the wharf, the crawler transfer equipment 100 can be flexibly arranged and combined according to the position of the material pile 21 and the position of the reclaimer 200, thereby improving the transfer efficiency.

[0051] The plurality of crawler transfer bridge machines 112 include a transition transfer bridge machine 113, a receiving transfer bridge machine 114 and a relay transfer bridge machine 115. One end of the transition transfer bridge machine 113 is connected to the crawler reclaimer 111, so as to receive the material 23 taken out from the material pile 21 by the crawler reclaimer 111, and the transition transfer bridge machine 113 forms the feeding end of the intermediate conveyor line. One end of the receiving transfer bridge machine 114 is connected to the transition transfer bridge machine 113, so as to receive the material 23 conveyed from the transition transfer bridge machine 113; one end of the relay transfer bridge machine 115 is connected to the other end of the receiving transfer bridge machine 114, so as to receive the material 23 conveyed from the receiving transfer bridge machine 114. The number of relay transfer bridge machines 115 in the crawler transfer equipment 100 is adjusted according to the distance from the receiving transfer bridge machine 114 to the reclaimer 200, and at the same time, Figure 2 As shown, generally, the stacking area of ​​the material 23 is relatively large. With the transfer of the material 23, the material reclaiming position of the crawler reclaimer 111 changes. Accordingly, the distance from the material receiving transfer bridge machine 114 to the reclaiming equipment 200 will change, and the number of relay transfer bridge machines 115 will also be adjusted accordingly with the transfer.

[0052] The conveying direction of the conveyor belt 139 of the transition bridge machine 113 intersects with the conveying direction of the conveyor belt 139 of the receiving bridge machine 114, and the transition bridge machine 113 is used to move along the extending direction of the conveyor belt 139 of the receiving bridge machine 114. Specifically, Figure 1 and Figure 2 As shown, in this embodiment, the material 23 is Figure 2 In the process of transferring materials 23, as the crawler reclaimer 111 takes materials, the crawler reclaimer 111 gradually moves to the left. Figure 2 The upper and lower directions of the material are arranged so as to receive the material 23 taken out by the crawler type reclaimer 111 and move along Figure 2 The material 23 is transported in a downward direction to the conveyor belt 139 of the receiving transfer bridge machine 114 arranged side by side with the crawler reclaimer 111. At the same time, during the process of the crawler reclaimer 111 gradually moving from right to left during the material reclaiming process, the crawler belt of the transition transfer bridge machine 113 operates synchronously so that the transition transfer bridge machine 113 moves from right to left along with the crawler reclaimer 111, and at the same time, the discharging end of the transition transfer bridge machine 113 always maintains a state of docking with the conveyor belt 139 of the receiving transfer bridge machine 114. In other words, the conveyor belt 139 of the receiving transfer bridge machine 114 moves along the Figure 2The length of the conveyor belt 139 of the material receiving transfer bridge machine 114 is the moving range of the transition transfer bridge machine 113 relative to the material receiving transfer bridge machine 114. When the moving distance of the crawler-type material reclaimer 111 is greater than the length of the conveyor belt 139 of the material receiving transfer bridge machine 114, the crawler of the material receiving transfer bridge machine 114 is adjusted to adjust the position. At this time, the number of relay transfer bridge machines 115 needs to be adjusted accordingly to ensure that the material 23 can be transported from the material receiving transfer bridge machine 114 to the crawler-type telescopic stacking machine 117 through the transportation of multiple relay transfer bridge machines 115. In other words, the relay transfer bridge machine 115 closest to the crawler-type telescopic stacking machine 117 forms the discharge end of the intermediate conveyor line. It can be understood that in some other embodiments, the material receiving transfer bridge machine 114 can also be set between the last relay transfer bridge machine 115 and the crawler-type telescopic stacking machine 117 for material transfer.

[0053] In this embodiment, the crawler reclaimer 111, the multiple crawler transfer bridge machines 112 and the crawler telescopic stacker 117 all have a circuit component 120, and the first active plug 125 of the circuit components 120 of two adjacent ones of the crawler reclaimer 111, the multiple crawler transfer bridge machines 112 and the crawler telescopic stacker 117 is plugged into and matched with the first socket 127 of the circuit component 120, so that the crawler reclaimer 111, the multiple crawler transfer bridge machines 112 and the crawler telescopic stacker 117 are powered in series.

[0054] Furthermore, the circuit assembly 120 further includes a first cable drum 126, and the cable of the first active plug 125 is wound on the first cable drum 126, so that the extension length of the first active plug 125 can be adjusted by retracting and releasing the cable through the first cable drum 126, thereby ensuring that two adjacent crawler devices can be plugged in. In other words, in this embodiment, if a circuit assembly 120 is provided with a first active plug 125, the circuit assembly 120 also has a first cable drum 126 for retracting and releasing the cable connected to the first active plug 125.

[0055] In this embodiment, the crawler transfer equipment 100 also includes a power supply trolley 150, which has a second movable plug 151 and a second socket 152. The second movable plug 151 is used to be plugged into a ground high-voltage socket, and the second socket 152 is used to be plugged into and cooperate with the first movable plug 125 of at least one of the crawler reclaimer 111, multiple crawler transfer bridge machines 112 and crawler telescopic stacker 117.

[0056] Figure 4 The circuit structure diagram of the power supply vehicle 150 provided in this embodiment is shown. Figure 1-Figure 4Optionally, in this embodiment, the circuit of the power supply trolley 150 is a one-input and two-output type, wherein the second movable plug 151 is located in one of the circuits, and the power supply is realized by plugging the first movable plug 125 into the ground high-voltage socket; the other two circuits are respectively provided with second sockets 152, so that the power supply trolley 150 can be plugged in and powered by two of the crawler reclaimer 111, multiple crawler transfer bridge machines 112, and crawler telescopic stackers 117 at the same time. Figure 3 As shown, in this embodiment, the first movable plugs 125 of the two relay bridge machines 115 are respectively plugged into the two second sockets 152 of the power supply trolley 150. Accordingly, at this time, the crawler reclaimer 111 and the crawler telescopic stacker 117 in the crawler transfer equipment 100 are both at the tail end of the power supply line, so the power supply circuit 128 in the crawler reclaimer 111 and the crawler telescopic stacker 117 can be set to have only the first movable plug 125, without the need to set the first socket 127.

[0057] It should be noted that the circuit setting of the power supply trolley 150 is not restricted here. It can be understood that in some other embodiments, the power supply trolley 150 can also be set to have only one second socket 152, so only one of the crawler reclaimer 111, multiple crawler transfer bridge machines 112 and crawler telescopic stackers 117 can be plugged into the power supply trolley 150. At this time, one of the crawler reclaimer 111 or the crawler telescopic stacker 117 is at the tail end of the power supply line. In this way, only the power supply circuit 128 at the tail end can be set to have only a first active plug 125, and there is no need to set a first socket 127.

[0058] Furthermore, the circuit of the power supply trolley 150 also has a second cable reel 153, and the cable of the second movable plug 151 is wound on the second cable reel 153. The cable of the second movable plug 151 can be retracted and released by rotating the second cable reel 153, thereby making the length of the second movable plug 151 adjustable, thereby meeting the power supply connection requirements from the ground high-voltage socket to the crawler device.

[0059] Figure 5 This is a schematic diagram of the power supply circuit 128 of the relay switching bridge machine 115 provided in this embodiment. Figure 1-Figure 5 In this embodiment, the circuit assembly 120 of the crawler bridge machine 112 also includes a ring main unit 121 and a circuit assembly 120. Figure 5The relay transfer bridge machine 115 is used as an example for introduction. The ring main unit 121 has a one-input and two-output switch circuit, in which the input circuit 122 of the one-input and two-output switch circuit is connected to the first socket 127, and the first output circuit 123 of the one-input and two-output switch circuit is connected to the first active socket, so that the input circuit 122 and the first output circuit 123 form a circuit for supplying power to another crawler device downstream; the second output circuit 124 of the one-input and two-output switch circuit is connected to the power supply circuit 128, so as to supply power to various electrical components in the crawler transfer bridge machine 112.

[0060] Specifically, since the crawler transfer equipment 100 requires at least more than 10 crawler devices and at most dozens of crawler devices according to different access processes and yard sizes, the maximum installed capacity of a single power supply line can reach more than 5000KW. A high-voltage power supply solution is selected, and each crawler device is equipped with a ring network cabinet 121, which has overcurrent and short-circuit protection functions to protect each device in the process. At the same time, the ring network gauge in the crawler device at the line terminal can also be equipped with a socket connection signal transmission element, which is interlocked with the upper switch cabinet through the element to protect the safety of the power transmission personnel.

[0061] Furthermore, the power supply circuit 128 also includes a power storage circuit 129, which is used to store electricity when the second power output circuit 124 is powered on, and is used to power the switch switching of the one-input and two-output switch circuit in the ring main unit 121. Specifically, the power storage circuit 129 has a UPS131 (Uninterruptible Power Supply). Optionally, the power storage circuit 129 is also electrically connected to the reel motor 132 of the first cable reel 126, so as to supply power to the reel motor 132, ensuring that the reel motor 132 can operate regardless of whether the first socket 127 is connected to a power source (for example, connected to the power supply trolley 150 through other crawler devices).

[0062] In this embodiment, the power supply circuit 128 of the relay transfer bridge machine 115 further includes a first interlocking switch 133, a first rectifier 134, a first branch 135, and a second branch 136. The first branch 135 and the second branch 136 are both connected to the first rectifier 134, the other end of the first branch 135 is connected to the chassis 137 of the relay transfer bridge, so as to supply power to the crawler drive joint of the relay transfer bridge machine 115, and the other end of the second branch 136 is connected to the belt conveyor 138 of the relay transfer bridge machine 115, so as to supply power to the conveyor belt 139 of the relay transfer bridge machine 115. The first interlocking switch 133 is arranged on the first branch 135 and the second branch 136, so that the first rectifier 134, the chassis 137, and the belt conveyor 138 are alternately energized. During the material 23 transfer process of the relay bridge machine 115, if the material 23 is being transported by the conveyor belt 139, there is no need to transfer the position of the entire machine, that is, the crawler structure does not need to operate at this time; if the entire machine is being transferred by the crawler structure, there is no need to transport the material 23. Therefore, by setting the first interlocking switch 133, the chassis 137 and the belt conveyor 138 are alternately connected to the first rectifier 134, so that the chassis 137 and the belt conveyor 138 can share the same rectifier, which helps to simplify the structure and reduce costs.

[0063] It should be noted that, since during the transfer process, the material receiving transfer bridge machine 114 and the transition transfer bridge machine 113 need to transfer the position of the entire machine while conveying the material 23 as the material 23 is transferred, the chassis 137 and the conveyor belt 139 in the material receiving transfer bridge machine 114 and the transition transfer bridge machine 113 are operated synchronously, and there is no need to set an interlocking switch between the first branch 135 and the second branch 136 in the power supply circuit 128 of the material receiving transfer bridge machine 114 and the transition transfer bridge machine 113.

[0064] Furthermore, a chassis battery pack 141 is also provided on the power supply circuit 128, and the chassis 137 can be powered by the chassis battery pack 141. Furthermore, the power supply circuit 128 of the relay bridge 115 also includes a first frequency converter provided downstream of the first rectifier 134, and the first frequency converter is located upstream of the first branch 135 and the second branch 136, so that the first branch 135 and the second branch 136 can share the first frequency converter.

[0065] Furthermore, an auxiliary power supply 142 is also provided on the power supply circuit 128 . When the relay bridge 115 exits or joins, if there is a temporary power outage in the power supply line, the auxiliary power supply 142 can be used for power supply.

[0066] Figure 6 This is a schematic diagram of the circuit assembly 120 of the variable amplitude transfer bridge machine 116 provided in this embodiment. Figure 1-Figure 6Furthermore, in this embodiment, part of the relay transfer bridge machine 115 is a structure with a pitch drive 143, and the pitch drive 143 drives the conveyor belt 139 of the relay transfer bridge machine 115 to rotate, thereby adjusting the pitch angle of the conveyor belt 139, thereby achieving the adjustment of the conveying angle. This type of relay transfer bridge machine 115 can be called a variable-length transfer bridge machine 116, and the relay transfer bridge machine 115 without a pitch drive 143 is a common relay transfer bridge machine (such as Figure 5 In this embodiment, the number of the common relay transfer bridge crane and the variable-length transfer bridge crane 116 in the crawler transfer equipment 100 can be set according to the needs of the dock transfer site.

[0067] In this way, the power supply circuit 128 in the luffing transfer bridge machine 116 also includes a pitch branch 144 , and the pitch branch 144 is connected to the pitch driving component 143 to supply power to the pitch driving component 143 .

[0068] Furthermore, in the present embodiment, the power supply circuit 128 of the circuit assembly 120 also includes a main power supply circuit 147, a third branch 145 and a fourth branch 146.

The third branch 145 and the fourth branch 146 are both connected to the main power supply circuit 147, wherein the third branch 145 is connected to the second power output circuit 124. In this way, when the ring network cabinet 121 is powered on, the main power supply circuit 147 can be powered by the third branch 145. The fourth branch 146 is provided with a low-voltage socket 149. Through the low-voltage socket 149, when the ring network cabinet 121 is not powered on, the main power supply circuit 147 can be powered by an external low-voltage battery power supply vehicle. A second interlock switch 148 is also provided on the third branch 145 and the fourth branch 146 to disconnect the fourth branch 146 when the third branch 145 is connected, and to disconnect the third branch 145 when the fourth branch 146 is connected, so that only one of the third branch 145 and the fourth branch 146 is connected to the main power supply circuit 147.

[0069] The crawler transfer equipment 100 and the crawler transfer system 10 provided by the embodiments of the present invention, due to the flexibility of the crawler device, can meet more flexible yard applications during the stacking process, and have higher transfer efficiency. At the same time, by setting the circuit components 120 of each crawler device and plugging in the first active plug 125 and the first socket 127, the power supply needs of the crawler device to exit and join at any time can be met.

[0070] The embodiment of the present invention further provides a dock material transfer method, which is implemented by using the above-mentioned crawler transfer device 100. Specifically, the dock material transfer method includes:

[0071] S01: Organize a crawler reclaimer 111, a plurality of crawler transfer bridge machines 112 and a crawler telescopic stacker 117 according to the position of the material pile 21 to form a crawler transfer equipment 100.

[0072] S02: Use a crawler-type reclaimer 111 to retrieve materials from the material pile 21, and use multiple crawler-type transfer bridge machines 112 and crawler-type telescopic stackers 117 to transport and transfer the materials 23.

[0073] In the process of the crawler reclaimer 111 retrieving materials, the number of crawler transfer bridge machines 112 is adjusted according to the distance between the crawler reclaimer 111 and the crawler telescopic stacker 117 .

[0074] Optionally, part of the relay transfer bridge machine 115 can be distributed along the stacking direction of the material pile 21. In this way, when the transfer of nearby materials 23 is completed, the crawler material reclaimer 111, the transition transfer bridge machine 113 and the material receiving transfer bridge machine 114 move forward along the stacking direction of the material pile 21. When transferring materials 23 in the distance, the number of relay transfer bridge machines 115 can be conveniently increased to meet the transfer needs.
