Description

Technical Field

[0001] The utility model mainly relates to the field of material sample collection and preparation, in particular to a docking device for a sample barrel transfer trolley. Background Art

[0002] In the existing coal quality sampling system, when the distance between the sampling end and the sample preparation end is greater than 100 meters, the transportation of coal samples is no longer suitable. The whole process is transported by roller conveyors, which is costly. In order to reduce costs, some practitioners have designed an automatic sample barrel transfer trolley to replace manual handling of sample barrels, which reduces labor intensity and is not costly.

[0003] However, when the existing transfer cart is docked with the target roller conveyor, the position of the target roller conveyor is usually fixed, and the transfer cart is movable. To achieve successful docking between the conveying mechanism on the transfer cart and the target roller conveyor, the driver needs to flexibly operate the steering wheel to ensure that the left and right deviation of the vehicle body does not exceed ±70mm. This requires too high driving skills of the driver. In actual operation, it is often necessary to adjust the vehicle body multiple times to successfully dock and realize the normal transfer of the sample barrel. The time wasted in adjusting the vehicle body will seriously affect the work efficiency of the entire sampling system. Some practitioners have designed docking devices. For example, CN202122292507.7 discloses a docking device for a sample barrel transfer cart. Although the docking device reduces the requirements for driving skills to a certain extent, it still has the following defects:

[0004] 1. Due to the limited width of the lap plate of the docking device, the reversing requirements of the transfer trolley during the reversing docking process are still relatively high;

[0005] 2. After the transfer cart stops reversing, the on-board conveying mechanism needs to be completely parallel to the docking device to ensure reliable automatic entry and exit of the sample barrel. During the reversing process, the driver only relies on the rearview mirror or reversing image to reverse, and it is impossible to ensure that the transfer cart and the conveying mechanism of the docking device are completely parallel. There is some inclination. When the inclination angle is too large, the barrel is prone to get stuck. Utility Model Content

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Embodiment 1

[0030] like Figures 1 to 4 As shown, this embodiment discloses a docking device for a sample barrel transfer cart, including a frame 1, on which is mounted a roller conveying mechanism 2 capable of forward and reverse conveying, the two sides of the roller conveying mechanism 2 are respectively docked with the onboard conveying mechanism 3 of the transfer cart and the external conveying equipment 4, so as to enable the sample barrel to be transferred between the transfer cart and the external conveying equipment 4, the roller conveying mechanism 2 is also provided with a hook barrel mechanism 5 for pushing the sample barrel to translate between the two ends of the frame 1, and also includes a telescopic roller mechanism 6, which docks with the onboard conveying mechanism 3 of the transfer cart through telescopic movement.

[0031] The docking device for the sample barrel transfer trolley in the present embodiment is designed with a telescopic roller mechanism 6. The telescopic roller mechanism 6 can be telescoped as needed to provide sufficient overlapping length, reducing the difficulty for the driver when reversing. When the transfer trolley is parked and tilted, the two ends of the telescopic roller mechanism 6 can be extended to different lengths in the direction close to the on-board conveying mechanism 3 of the transfer trolley, and the sample barrel can still be reliably transported from the on-board conveying mechanism 3 of the transfer trolley to the docking device, reducing the requirement for parallelism between the vehicle and the docking device when reversing. The docking process is simple and reliable, which greatly reduces the difficulty for operators and can improve the work efficiency of the system.

[0032] In this embodiment, the telescopic roller mechanism 6 includes a fixed roller assembly 61, a first transmission assembly, a telescopic roller assembly 62, a second transmission assembly 63, two sets of telescopic connecting rod assemblies 64 and two sets of driving assemblies 65. The fixed roller assembly 61 is connected to the roller conveying mechanism 2 through the first transmission assembly, the telescopic roller assembly 62 is connected to the fixed roller assembly 61 through the second transmission assembly 63, the two sets of telescopic connecting rod assemblies 64 are respectively connected to the two ends of the telescopic roller assembly 62, and the two sets of driving assemblies 65 respectively drive the two sets of telescopic connecting rod assemblies 64 to move to drive the telescopic roller assembly 62 to approach and dock the vehicle-mounted conveying mechanism 3 of the transfer trolley. Further, in a preferred embodiment, the first transmission assembly is a chain drive or a belt drive, and the second transmission assembly 63 is any one of an elastic rubber band, an O-ring, and an elastic V-belt.

[0033] In this embodiment, the roller conveying mechanism 2 is connected to the fixed roller assembly 61 through a chain transmission, driving the fixed roller assembly 61 to rotate forward and backward. The fixed roller assembly 61 is connected to the telescopic roller assembly 62 through an elastic rubber band. The elastic rubber band transmits the rotational power of the fixed roller assembly 61 to the telescopic roller assembly 62, driving the telescopic roller assembly 62 to rotate forward and backward. The telescopic connecting rod assembly 64 is a multi-link mechanism (such as two groups of four-link mechanisms), and the four-link mechanism can achieve uniform spacing between two or more telescopic roller assemblies 62, and can be retracted freely. Since the two ends of the telescopic roller assembly 62 are driven respectively by two groups of driving assemblies 65, the two ends of the telescopic roller assembly 62 can be made to extend forward to different lengths. When the transport trolley is parked and tilted, the different lengths of the two ends of the telescopic roller assembly 62 make the telescopic roller assembly 62 also tilted, which can just dock with the vehicle-mounted conveying mechanism 3, thereby realizing reliable automatic transportation of the sample barrel.

[0034] In this embodiment, a separation plate 7 is also included, and the separation plate 7 is arranged between the telescopic roller assembly 62 and the vehicle-mounted conveying mechanism 3 of the transfer vehicle. Further, in a preferred embodiment, the telescopic roller assembly 62 is at least two groups, and the separation plate 7 is arranged below a group of telescopic roller assemblies 62 that is closer to the vehicle-mounted conveying mechanism 3. When the telescopic roller assembly 62 extends forward, the separation plate 7 extends forward at the same time, and the separation plate 7 first docks with the vehicle-mounted conveying mechanism 3, so that there is a certain gap between the telescopic roller assembly 62 and the vehicle-mounted conveying mechanism 3, so as to avoid the phenomenon that the telescopic roller assembly 62 and the roller of the vehicle-mounted conveying mechanism 3 are directly in contact and stuck.

[0035] In this embodiment, bosses 8 are provided at both ends of the telescopic roller assembly 62, and the second transmission assembly 63 (such as an elastic rubber band) is wound around the surface of the boss 8. By winding the elastic rubber band around the position with the boss 8, the elastic rubber band can be prevented from deviating to the left and right; because the width of the boss 8 is smaller than the width of the elastic rubber band, when the telescopic roller assembly 62 rotates, the elastic rubber band is stressed, and there is a situation that the middle is tight and the two sides are loose, which can realize the elastic rubber band automatically returning to the center.

[0036] In this embodiment, the surface of the boss 8 is provided with anti-skid patterns (such as knurling), which can increase the friction force and reduce the possibility of the elastic rubber band deviating to the left and right.

[0037] In this embodiment, the frame 1 is also provided with a barrel-blocking and limiting mechanism 9 and a lifting and lowering driving mechanism (such as a cylinder, a motor or a linear mold). The barrel-blocking and limiting mechanism 9 is driven by the lifting and lowering driving mechanism to lift and lower the sample barrels, so as to control the entry and exit of the sample barrels. The lifting and lowering driving mechanism drives the barrel-blocking and limiting mechanism 9 to lift and lower, so as to control the entry and exit of the sample barrels in an orderly manner, avoid collisions between sample barrels during transportation and cause them to fall, improve the safety and reliability of the sample barrels during transportation, and effectively ensure the safety and representativeness of the samples.

[0038] In this embodiment, the bucket-stopping and limiting mechanism 9 includes a first bucket-stopping and limiting mechanism 91 and a second bucket-stopping and limiting mechanism 92, and the first bucket-stopping and limiting mechanism 91 and the second bucket-stopping and limiting mechanism 92 are respectively arranged on both sides of the roller conveying mechanism 2. The hook-bucket mechanism 5 includes four hook-bucket assemblies and a synchronous drive assembly, and the hook-bucket assembly is driven by the synchronous drive assembly to translate along the vertical movement direction of the roller conveying mechanism 2. In other embodiments, multiple hook-bucket assemblies can also be provided.

[0039] Working principle: When the transfer trolley loaded with sample barrels reverses and stops at the docking device, if the onboard conveying mechanism 3 of the transfer trolley is not parallel to the roller conveying mechanism 2 of the docking device, the two sets of driving components 65 drive the two ends of the telescopic roller component 62 to extend to different lengths to compensate for the tilt angle of the parking of the transfer trolley, so that the telescopic roller component 62 can successfully dock with the onboard conveying mechanism 3; when the transfer trolley completes the docking with the docking device, the first barrel blocking limit mechanism 91 remains in the lowered position, and the second barrel blocking limit mechanism 92 is in the raised position, The on-board conveying mechanism 3 on the transport trolley and the roller conveying mechanism 2 of the docking device operate simultaneously, and the four sample barrels are moved from the transport trolley to the docking device. Then, the first barrel blocking and limiting mechanism 91 rises upward. At this time, the roller conveying mechanism 2 of the docking device stops operating, and the hook barrel mechanism 5 translates the four sample barrels to the entrance of the external conveying device 4 at one time. The second barrel blocking and limiting mechanism 92 descends, and the roller conveying mechanism 2 of the docking device and the external conveying device 4 operate simultaneously, and the sample barrels are moved from the roller conveying mechanism 2 of the docking device to the external conveying device 4. When it is necessary to transfer the sample barrels from the external conveying device 4 to the on-board conveying mechanism 3 of the transport trolley, the control process is the opposite of the above process.

[0042] In this embodiment, the single crank multi-slider assembly 66 includes a first connecting rod 661, a second connecting rod 662 and a crank 663. The first connecting rod 661 and the second connecting rod 662 are connected to the crank 663. The driving assembly 65 is used to drive the crank 663 to rotate and thereby drive the first connecting rod 661 and the second connecting rod 662 to move.

[0043] The telescopic roller assembly 62 can also be telescopically moved by the single crank multi-slider assembly 66 to achieve docking with the vehicle-mounted conveying mechanism 3 .
