[0003] Taking an auxiliary vehicle mainly used for loading and transporting materials as an example, after the materials inside the auxiliary vehicle are transported to the designated location, they generally need to be manually taken out from the top of the trolley for unloading, which is very inconvenient. For example, Patent No. CN214420442U discloses a subway construction safety auxiliary vehicle, which facilitates unloading of the goods in the trolley by setting the turn plate as an openable structure. However, this structure still requires manual operation when opening the turn plate, and the trolley may cause the materials to tip to one side due to unstable center of gravity during transportation. When manually opening the turn plate, it is easy to be hit by the tipped materials, which not only poses a threat to the life and health of construction workers, but may also lead to delays in construction progress and increased costs.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0020] See also Figure 1-4 The present invention provides an embodiment of a safety auxiliary vehicle for subway construction, comprising a vehicle body 1, a track 2, a discharge door 7, and a discharge port 21. Tracks 2 are provided on both sides of the lower portion of the vehicle body 1, and the four corners of the bottom portion of the vehicle body 1 are connected to the track 2 via a base 11.
[0021] Brackets 13 are provided on both sides of the base 11, and guide wheels 12 are provided inside the brackets 13, and one end of the guide wheel 12 is in contact with the track 2;
[0022] The car body 1 is filled with materials for subway construction, which are pulled to the car body 1 by traction equipment and moved to the construction location. The bottom of the car body 1 is connected to both sides of the track 2 through guide wheels 12;
[0023] Screws 14 are passed through both sides of the base 11, and one end of the screws 14 is connected to the bracket 13. By rotating the screws 14, the guide wheels 12 can be driven to adjust their position relative to the track 2, which is conducive to timely replenishing the position when the guide wheels 12 are worn, so that the vehicle body 1 is not prone to shaking or disengagement when moving;
[0024] A slide groove 18 is provided at the top of the base 11, and the interior of the slide groove 18 is in sliding contact with the track 2 via a ball bearing to assist the movement of the vehicle body 1;
[0025] A load-bearing plate 9 is provided at the bottom of the vehicle body 1, and weighing sensors 10 are provided at the four corners below the load-bearing plate 9;
[0026] The top of the weighing sensor 10 is provided with a support 17, and a pressure piece 15 is provided above the support 17. The top of the pressure piece 15 is connected to the bottom end of the bearing plate 9, and a steel ball 16 is provided between the pressure piece 15 and the support 17.
[0027] The material is placed on the load-bearing plate 9 in the vehicle body 1. After the pressure piece 15 is subjected to force, it acts on the support piece 17 through the steel ball 16 and then transmits it to the weighing sensor 10, which is conducive to sensing the weight of the material and preventing the material from being overweight. After weighing, the steel ball 16 automatically resets under the arc action between the pressure piece 15 and the support piece 17, making it less likely for the pressure piece 15 to deviate, thereby improving the sensing accuracy of the weighing sensor 10;
[0028] Guide grooves 19 are provided on both sides of the vehicle body 1, and guide blocks 20 matching the guide grooves 19 are provided on both sides of the load-bearing plate 9 for guiding and limiting the load-bearing plate 9;
[0029] A discharge port 21 is provided on one side of the vehicle body 1, and a discharge door 7 is provided on the outside of the discharge port 21. A rotating shaft 3 is provided on the vehicle body 1 on the side of the discharge door 7 through a frame 4, and connecting rods 6 are provided at both ends of the rotating shaft 3. The side of the connecting rod 6 close to the discharge door 7 is evenly connected to the discharge door 7 through a connecting plate 8.
[0030] A driving motor 5 is fixed to the top of the frame 4, and the output end of the driving motor 5 is connected to the rotating shaft 3;
[0031] When the vehicle body 1 transports the material to the designated location, the drive motor 5 drives the rotating shaft 3 to rotate, and the connecting rod 6 pulls the connecting plate 8 to rotate, thereby driving the unloading door 7 to rotate and open, and then the material can be taken out through the unloading port 21;
[0032] The discharge door 7 can be opened quickly, so that the material can be discharged quickly and accurately, which improves the discharge efficiency, eliminates the need for manual operation, avoids the errors that may be caused by manual operation, thereby improving safety, and reduces the need for manual operation, thereby reducing labor costs;
[0033] The specific models and specifications of the drive motor 5 and the weighing sensor 10 need to be determined by selection calculation based on the specification parameters of the device. The selection calculation method is existing technology and will not be described in detail.
[0034] Working principle: When the embodiment of the present application is in use, the car body 1 is filled with materials for subway construction, which are pulled to the car body 1 by traction equipment and moved to the construction position. The bottom of the car body 1 is connected to both sides of the track 2 through the guide wheel 12. By rotating the screw 14, the guide wheel 12 can be driven to adjust the position between the track 2, which is conducive to timely filling the position when the guide wheel 12 is worn, so that it is not easy to shake or get out of touch when the car body 1 moves. The material is placed on the bearing plate 9 in the car body 1. After the pressure piece 15 is subjected to force, it acts on the support piece 17 through the steel ball 16 and is then transmitted to the weighing sensor 10, which is conducive to sensing the weight of the material and avoiding overweight of the material. After the weighing is completed, The steel ball 16 automatically resets under the arc action between the pressure piece 15 and the support piece 17, making it difficult for the pressure piece 15 to deviate. When the vehicle body 1 transports the material to the designated location, the driving motor 5 can be used to drive the rotating shaft 3 to rotate, and the connecting rod 6 can be used to pull the connecting plate 8 to rotate, thereby driving the unloading door 7 to rotate and open. After that, the material can be taken out through the unloading port 21, so that the unloading door 7 can be opened quickly, so that the material can be unloaded quickly and accurately, thereby improving the unloading efficiency, eliminating the need for manual operation, avoiding the errors that may be caused by manual operation, thereby improving safety, and reducing the need for manual operation, thereby reducing labor costs.
