[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0023] refer to Figure 1-Figure 7 The utility model provides a multi-drive iron-clad tractor, comprising a frame 11, a front wheel pair 9 and a rear wheel pair 10 are arranged below the frame 11, each wheel in the front wheel pair 9 or / and the rear wheel pair 10 is connected to a reduction motor 14, a power supply system 18 is arranged to be connected to the reduction motor 14, each wheel is a double-edge structure, a first train coupler structure 15 is arranged in front of the frame 11, an automatic unhooking structure 17 is arranged on the frame 11 above the first train coupler structure 15, and a second train coupler structure is arranged at the rear of the iron-clad frame 2, the automatic unhooking structure 17 comprises an electro-hydraulic push rod 1701, a connecting ring 1702 and a limit pin 1703, the electro-hydraulic push rod 1701 is tilted and fixedly connected to the frame 11, a connecting ring 1702 is movably arranged at the output end of the lower end of the electro-hydraulic push rod 1701, the other end of the connecting ring 1702 is movably connected to the limit pin 1703, and the limit pin 1703 is movably inserted in the first train coupler structure 15.
[0024] In this embodiment, each wheel in the front wheel pair 9 is connected to a reduction motor 14 .
[0025] During the working process, the locomotive 1 pushes the iron-clad frame 2 loaded with the iron-clad 3 into the No. 1 working position 6. After the iron-clad 3 is aligned, the staff in the locomotive 1 or the on-site staff perform manual unhooking operations to separate the locomotive 1 from the iron-clad frame 2. Then the locomotive 1 leaves the current working area and goes to other working places to carry out transportation operations. The iron-clad 3 aligned to the No. 1 working position 6 performs relevant production operations. After the belt operation is completed, the multi-drive iron-clad tractor 4 is started, and the power supply system 18 supplies power to the two reduction motors 14 at the same time. The reduction motor 14 drives the front wheel pair 9 to rotate, providing power for the utility model. The rear wheel pair 10 rotates synchronously with the front wheel pair 9, driving the frame 11 to run in the direction of the iron-clad 3. The utility model gradually approaches the iron-clad frame 2 until the first train coupler structure 15 collides with the second train coupler structure to complete the hooking operation. Then the utility model drags the iron-clad frame 2 loaded with the iron-clad 3 into the No. 2 working position 7. If the related production operation of the iron bag 3 at the second working position 7 is highly dangerous or prone to material spillage, splashing, etc., the automatic unhooking structure 17 can be started before the iron bag 3 is operated to perform the automatic unhooking operation. The electro-hydraulic push rod 1701 is started by remote operation, and the electro-hydraulic push rod 1701 shrinks and shortens, pulling the connecting ring 1702. At the same time, the limit pin 1703 is lifted a distance due to the upward pulling force but will not be separated from the coupler structure. At this time, the first train coupler structure 15 is in a loose state, and the utility model is controlled to run away from the iron bag 3, separate it from the iron bag frame 2, and return to the initial position 8 to wait. After the operation is completed, it drives to the iron bag 3 and completes the hooking operation with the iron bag frame 2. After the iron bag 3 completes the relevant operation at the second working position 7, the utility model is started, and the iron bag frame 2 loaded with the iron bag 3 is pushed to the waiting position 5. After the alignment is completed, the automatic unhooking structure 17 is started to perform the automatic unhooking operation, and the utility model is separated from the iron bag frame 2, and the utility model is controlled to move away from the iron bag 3 and return to the initial position 8, so that a workflow ends. The iron bag frame 2 loaded with the iron bag 3 waits at the waiting position 5 for the locomotive 1 to transport it to the next work site.
[0026] As a more preferred embodiment, a counterweight structure 13 is provided on the upper rear side of the frame 11. The counterweight structure 13 provides a balancing force for the utility model to prevent tipping accidents during operation.
[0027] In order to cause damage during a collision, as an improvement, a buffer 16 is provided at the rear of the frame 11, and the buffer 16 includes a first buffer slider 1601, a second buffer slider 1602, a third buffer slider 1603 and a pressure sensor 1604. The first buffer slider 1601 is slidably connected in the sliding cavity of the second buffer slider 1602, and a first spring 1605 is provided in the sliding cavity of the second buffer slider 1602. One end of the first spring 1605 is connected to the first buffer slider 1601, and the other end is connected to the inner wall of the sliding cavity of the second buffer slider 1602. The second buffer slider 1602 is slidably connected in the sliding cavity of the third buffer slider 1603. A second spring 1606 is provided in the sliding cavity of the third buffer slider 1603, one end of the second spring 1606 is connected to the second buffer slider 1602, and the other end is connected to the inner wall of the sliding cavity of the third buffer slider 1603. A pressure sensor 1604 is provided between the third buffer slider 1603 and the frame 11.
[0028] When the rear of the vehicle frame 11 is too close to another vehicle or object and collides with it, it first contacts the first buffer slider 1601, and the first buffer slider 1601 is pushed to slide into the sliding cavity of the second buffer slider 1602, and the first buffer is performed by the first buffer slider 1601. When the first buffer slider 1601 completely enters the sliding cavity of the second buffer slider 1602, the other vehicle or object continues to push the second buffer slider 1602 to slide into the sliding cavity of the third buffer slider 1603 (in the process of sliding of the first buffer slider 1601, part of the second buffer slider 1602 may have entered the sliding cavity of the third buffer slider 1603), and the second buffer is performed by the second buffer slider 1602. When the second buffer slider 1602 completely enters the sliding cavity of the third buffer slider 1603, the vehicle frame 11 and the other vehicles or objects squeeze the pressure sensor 1604, and the pressure sensor 1604 transmits a signal to the control, and the controller controls the parking.
[0029] As a specific sliding connection method, at least two sliding rails are respectively provided on the first buffer slider 1601 and the second buffer slider 1602, and the inner walls of the sliding cavities of the second buffer slider 1602 and the third buffer slider 1603 are provided with sliding grooves with the same number as the sliding rails. The sliding rails of the first buffer slider 1601 match the sliding grooves in the sliding cavity of the second buffer slider 1602, and the sliding rails of the second buffer slider 1602 match the sliding grooves in the sliding cavity of the third buffer slider 1603.
[0030] The matching mode of the slide rail and the slide groove can make the sliding process more stable.
[0031] In order to provide prompts during the working process, as an improvement of the technical solution, sound and light alarms 19 are respectively provided on both sides of the front of the frame 11. During the operation, the sound and light alarms 19 simultaneously emit alarm sounds and prompt lights to prevent accidents.
[0032] In order to realize automatic control, as an improvement, a remote controller is further included, and the reduction motor 14, the electro-hydraulic push rod 1701, and the sound and light alarm 19 are all connected to the remote controller.
[0033] In order to achieve accurate control of the distance, an infrared rangefinder is provided in front of the frame 11, and accurate positioning is achieved under the action of the infrared rangefinder.
[0034] In order to make the utility model more beautiful as a whole and to protect the internal components, preferably, a protective cover 12 is provided above the frame 11 .
