When in use, if a dangerous situation occurs, the trailer can be immediately stopped after pressing the emergency stop button; the frame 2 comprises a horizontally arranged first crossbeam 21, and two oppositely arranged second crossbeams 22 are mounted at both ends of the first crossbeam 21. The second crossbeams 22 are both perpendicular to the first crossbeam 21 in the horizontal direction, and are positioned A steering wheel 31 with a steering function is installed on the first crossbeam 21 between the two second crossbeams 22. The steering wheel 31 can make the trailer turn during movement, so that the trailer can be moved at will; each second crossbeam 22 is rotatably connected to the drive wheel 9 at one end away from the first crossbeam 21. The drive wheels 9 are respectively located on the outside of the second crossbeam 22, and one of the drive wheels 9 is transmission-connected to the drive mechanism 4. The electric control box 8 is located on the side of the first crossbeam 21 away from the second crossbeam 22 and is electrically connected to the drive mechanism 4 and the steering wheel mechanism 3 respectively. Specifically, when in use, the drive mechanism 4 can drive the drive wheel 9 to rotate to realize the movement of the trailer.

[0026] In addition, both ends of each second cross beam 22 are also equipped with a first electric telescopic rod 1 that is vertically distributed and electrically connected to the electric control box 8. The top ends of the first electric telescopic rods 1 are all telescopic ends and are respectively located on the inner sides of the second cross beam 22, and the four first electric telescopic rods 1 are relatively arranged on the side of the steering wheel 31 away from the first cross beam 21. Specifically, in the initial state, the telescopic ends of the first electric telescopic rods 1 are all in a retracted state; when in use, the driving wheel 9 can be driven to rotate by the driving mechanism 4, and by providing the steering wheel 31, it is convenient to drive the trailer to the position where the feeding trough 11 is located, until the four first electric telescopic rods 1 are all located below the feeding trough 11, the telescopic ends of the first electric telescopic rods 1 can be gradually extended, and then the feeding trough 11 can be lifted up. At this time, the driving wheel 9 can be driven to rotate in the opposite direction by the driving mechanism 4 to move out of the feeding trough 11, so that the feeding trough can be easily adjusted. 11 for transportation; in addition, the feed trough base 12 can also be fixedly installed on the feed trough 11, and a groove 13 opposite to the position of the first electric telescopic rod 1 can be provided on the feed trough base 12 for cooperation. For example, when the distance between the two second beams 22 is greater than the specification of the feed trough 11, the feed trough base 12 arranged parallel to the second beam 22 can be fixedly installed on both sides of the feed trough 11, and a groove 13 opposite to the position of the first electric telescopic rod 1 is provided on each feed trough base 12. At this time, when the four first electric telescopic rods 1 are located below the feed trough base 12 and opposite to the groove 13 on the feed trough base 12, the telescopic end of the first electric telescopic rod 1 is gradually extended into the groove 13, so as to lift the feed trough 11 for transportation; that is, the utility model is a special transportation equipment for the feed trough 11, which can facilitate the transportation of the feed trough 11.

[0027] Secondly, the layout of the electric control box 8, the driving wheel 9, the steering wheel 31 and the first electric telescopic rod 1 on the frame 2 is compact and reasonable, which can facilitate the assembly of the trailer.

[0028] The specific configuration of the steering wheel 31 is as follows: Figures 1 to 3As shown, a horizontally arranged load frame 32 is installed on the first crossbeam 21 located between the two second crossbeams 22, and a wheel frame 33 is hinged on the side of the load frame 32 close to the second crossbeam 22, and a second electric telescopic rod arranged horizontally and electrically connected to the electric control box 8 is hinged between the load frame 32 and one of the wheel frames 33, and the wheel frame 33 is rotatably connected to the side of the load frame away from the load frame, and a horizontally distributed connecting rod 34 is hinged between the two wheel frames 33. The steering wheel 31, the load frame 32, the second electric telescopic rod, the wheel frame 33 and the connecting rod 34 can form a steering wheel mechanism 3. Specifically, when in use, when the axial line of the steering wheel 31 is parallel to the axial line of the driving wheel 9, that is, in the initial state, the telescopic end of the second electric telescopic rod is in a semi-extended state; and when the telescopic end of the second electric telescopic rod is in the process of telescoping, it can drive the wheel frame 33 to rotate. At this time, under the action of the connecting rod 34, the two steering wheels 31 can be synchronously steered to drive the trailer to steer.

[0029] The specific configuration of the driving mechanism 4 is as follows: Figure 1 and Figure 4 As shown, the drive mechanism 4 includes a drive motor horizontally mounted on the second crossbeam 22 and equipped with a brake. The output shaft of the drive motor is parallel to the first crossbeam 21, and a wheel axle is mounted on the output shaft of the drive motor. The drive wheel 9 is mounted on the wheel axle. The electric control box 8 is electrically connected to the drive motor. Specifically, the drive motor with a brake is built into the drive wheel 9. During use, when the drive motor is started, the drive wheel 9 can be driven to rotate, and the brake can brake the drive motor.

[0030] Further, such as Figure 1 and Figure 5 As shown, the drive motor is a hydraulic motor, and the first electric telescopic rod 1 and the second electric telescopic rod are both hydraulic cylinders. A hydraulic pump station 5 with an oil tank is installed on the side of the first crossbeam 21 away from the second crossbeam 22. The hydraulic pump station 5 is electrically connected to the electronic control box 8 and is respectively connected to the first electric telescopic rod 1, the second electric telescopic rod, and the drive motor. Specifically, the hydraulic pump station 5 mainly consists of an oil tank, a drive device, a control valve group, and pipelines. The oil tank, the drive device, the functional valve group, and the hydraulic cylinder / motor are mainly connected by hydraulic hoses. The control valve group is controlled by an electric proportional multi-way valve, which can realize manual direct operation and electrical remote control operation. All control valve groups are equipped with back-pressure valves and pressure compensators to maintain the pressure at an appropriate rated load. When in use, the drive motor, the first electric telescopic rod 1, and the second electric telescopic rod are all driven by the hydraulic pump station 5, which can achieve full hydraulic drive of the trailer. In addition, when the hydraulic pump station 5 stops providing hydraulic power to the drive motor, it can automatically activate the brake of the drive mechanism 4 to brake.

[0031] Furthermore, a U-shaped frame 23 is fixedly connected to the bottom surface of each second crossbeam 22, and a third electric telescopic rod 6 is installed on the U-shaped frame 23, which is arranged parallel to the second crossbeam 22 and passes through the U-shaped frame 23. The third electric telescopic rod 6 is a hydraulic cylinder, and the end of the third electric telescopic rod 6 away from the first crossbeam 21 is a telescopic end, and the other end of the third electric telescopic rod 6 is hinged to the second crossbeam 22, the electric control box 8 is electrically connected to the third electric telescopic rod 6, and the hydraulic pump station 5 is connected to the third electric telescopic rod 6. In the initial state In this state, the telescopic end of the third electric telescopic rod 6 is in a retracted state; specifically, during use, when the trailer starts and drives the feed trough 11 away from the grinder, a fixing seat 10 opposite to the position of the third electric telescopic rod 6 can be provided at the end of the second beam 22 away from the first beam 21, and the fixing seat 10 is fixed with anchor bolts. Then, when the telescopic end of the third electric telescopic rod 6 is extended to abut against the fixing seat 10, the telescopic end of the third electric telescopic rod 6 continues to extend, which can assist the trailer in starting and driving the feed trough 11 away from the grinder.

[0032] Furthermore, displacement sensors are installed in the first electric telescopic rods 1, and the displacement sensors are electrically connected to the electrical control box 8. Specifically, the displacement sensors are pull-wire displacement sensors and are built into the first electric telescopic rods 1. When in use, the displacement sensors can monitor the telescopic heights of the four first electric telescopic rods 1 in real time, and then the electrical control box 8 can calculate the height difference between the first electric telescopic rods 1 in real time based on the height signal fed back by the pull-wire sensor to judge the speed, and then the telescopic speed of the first electric telescopic rods 1 can be changed in real time, so that the telescopic height difference of the four first electric telescopic rods 1 can be controlled in real time within a certain error range, thereby achieving synchronous jacking and synchronous descent; in addition, if the height difference exceeds the set safety value, the operation will stop immediately.

[0033] Furthermore, a liquid level sensor and a temperature sensor are installed in the oil tank, and the electronic control box 8 is electrically connected to the liquid level sensor and the temperature sensor respectively. Specifically, when in use, the liquid level sensor can be used to monitor the oil level of the hydraulic oil in the oil tank in real time, and then when the liquid level sensor detects that the oil level of the hydraulic oil is too low, the hydraulic pump station 5 can be shut down through the electronic control box 8, and the hydraulic pump station 5 cannot be restarted before the oil tank is filled with oil; and the temperature sensor can be used to monitor the temperature of the hydraulic oil in the oil tank in real time, and then when the temperature sensor detects that the temperature of the hydraulic oil is too high, the hydraulic pump station 5 can also be shut down, and the hydraulic pump station 5 cannot be restarted before the temperature of the hydraulic oil drops to an appropriate temperature. This can protect the hydraulic pump station 5 to prevent accidents.

[0034] Further, the first cross beam 21 is installed with an operation table 7 on the side away from the second cross beam 22, and a plurality of operating rods electrically connected with the electric control box 8 are installed on the operation table 7, specifically, the operating rods include operating rods for controlling the movement of the trailer and the operation of the electric telescopic rod, so that the trailer can be manually controlled to run in use; in addition, a remote controller signal connected with the electric control box 8 can be arranged to remotely control the trailer.

[0035] Further, the top surface of each second cross beam 22 is installed with a laser positioner electrically connected with the electric control box 8, and the laser positioner is opposite to the position of the first electric telescopic rod 1, specifically, in use, before the trailer is used to transport the feeding trough 11 for the first time, the laser positioner can be used to mark the sensing area that can be detected by the laser positioner on the feeding trough 11, so that the trailer can be moved to the position and the feeding trough 11 can be transported, or the four first electric telescopic rods 1 can be aligned with the four grooves 13 on the feeding trough base 12.

[0036] Further, the frame 2 is installed with an audible and visual alarm electrically connected with the electric control box 8, specifically, in use, when the trailer is running, the audible and visual alarm can emit sound and light to achieve the warning effect, so that the personnel who accidentally approach the transportation site can be avoided.
