Based on a dolly for machining that second embodiment provided, still need the manual work to extract bolt 20 before actual unloading, this process is wasted time and energy, if operating personnel forget to extract bolt 20 because of carelessness momentarily, then the inside spare part of freight warehouse 6 can extrude door 8 when baffle 14 top landing to door 8 department and cause the damage, unload in same position certain time back simultaneously, spare part can pile up to freight warehouse 6 bottom gradually, if not drive the dolly forward in time this moment, change the discharge position, thereby spare part on ground can extrude 6 afterbody of freight warehouse and cause the damage to freight warehouse 6, in order to solve this problem, improve the adaptability and the easy operability of device, combine fig. 7 and fig. 8, this kind of machining dolly still includes: a spring 21 is arranged on the outer side of the bin gate 8, a latch 20 is arranged at the other end of the spring 21, the latch 20 penetrates through the bin gate 8, a first magnetic block 22 is arranged at the other end of the latch 20, an arc-shaped groove 29 is formed in the top of one side, close to the bin gate 8, of the baffle 14, the groove depth of the arc-shaped groove 29 is gradually increased towards the middle position along the top, therefore, the latch 20 penetrates through the bin gate 8 and is in mutual sliding connection with the arc-shaped groove 29, the limiting effect of the latch 20 on the bin gate 8 and the baffle 14 is achieved, a second magnetic block 30 is arranged at the position, corresponding to the first magnetic block 22, of the arc-shaped groove 29, the first magnetic block 22 and the second magnetic block 30 are opposite in magnetism, therefore, when the baffle 14 and the bin gate 8 are placed side by side, the first magnetic block 22 and the second magnetic block 30 are attracted through magnetic attraction, the spring 21 is extruded by the latch 20, when the baffle 14 is driven by the first air cylinder 9 and the second air cylinder 31 to slide obliquely in the interior of the bin 6, the baffle 14, the second magnetic block 30 is separated from the first magnetic block 22, the bolt 20 is separated from the baffle 14 under the elastic action of the spring 21 and slides in the bin gate 8 to a certain degree and then is stabilized, the second pressure sensor is arranged in the first magnetic block 22 for detecting the pressure value applied to the first magnetic block 22, the buzzer is arranged in the bolt 20, the buzzer and the second pressure sensor are electrically connected, when the first magnetic block 22 and the second magnetic block 30 are magnetically attracted, the pressure value is a certain value, which indicates that the bin gate 8 and the baffle 14 in the cargo bin 6 are tightly closed, the situation that parts fall along the bin gate 8 cannot occur, meanwhile, when unloading is performed, the parts in the cargo bin 6 reach the bottom of the bin gate 8 along the top of the baffle 14 and push the bin gate open for unloading, when the parts are stacked to a certain degree, the top of the part stack touches the second pressure sensor, the second pressure sensor detects the pressure value and when the pressure value reaches the set pressure threshold, the second pressure sensor can detect alarm signal and transmit for bee calling organ, and the inside controller of bee calling organ can start bee calling organ and report to the police this moment to remind operating personnel to need move the dolly forward, change the discharge place, prevent that spare part piles up and cause the damage to the dolly afterbody.

When the cargo unloading device is used, when the cargo is not unloaded, the baffle plate 14 is positioned on the inner side of the bin door 8, the bolt 20 extrudes the spring 21 to penetrate through the bin door 8, the first magnetic block 22 at the end part of the bolt 20 is positioned in the arc-shaped groove 29 of the baffle plate 14 and is magnetically attracted with the second magnetic block 30, the pressure value detected by the second pressure sensor is a certain value at the moment, the tightness and the bearing capacity of the cargo bin 6 are illustrated, when the cargo is required to be unloaded, the hydraulic cylinder 26 is started to drive the cargo bin 6 to rotate along the second rotating shaft 23, the first air cylinder 9 is started to drive the bottom of the baffle plate 14 to move inwards, the second air cylinder 31 is started to drive the third air cylinder 33 to move downwards, so that the baffle plate 14 is driven to change from the original vertical placement into the inclined state, the first magnetic block 22 is separated from the second magnetic block 30 at the moment, the pressure value detected by the second pressure sensor is gradually reduced to zero, and the first magnetic block 22 is gradually separated from the baffle plate 14 along the arc-shaped groove 29, the spring 21 drives the bolt 20 to retract along the bin door 8 by means of elasticity of the spring, parts in the cargo bin 6 fall to the bottom of the bin door 8 along the top of the baffle 14, and gradually push the bin door 8 to unload along the bottom of the bin door 8, so that the bin door 8 is automatically opened when the unloading is needed, and the problem that the cargo bin 6 is damaged and serious safety accidents occur due to the fact that an operator forgets to open the bin door 8 is avoided.

In the unloading process, parts are gradually accumulated at a certain position, when the height of the part stack is gradually increased and reaches the tail part of the cargo bin 6, the top of the part stack can apply upward supporting force to a second pressure sensor inside the second magnetic block 30, the pressure value detected by the second pressure sensor is gradually increased until the pressure value reaches a set pressure threshold value, the second pressure sensor can transmit an alarm signal to a buzzer, a controller inside the buzzer can start the buzzer to alarm, so that an operator is reminded of pulling the trolley to replace an unloading place, after the trolley is pulled to the trolley replacing place, the pressure value detected by the second pressure sensor is gradually reduced, the buzzer stops working at the moment, and the unloading process is continued.
