Description

Technical Field

[0001] The utility model relates to the technical field of aggregate sampling, in particular to a lifting and sampling device. Background Art

[0002] After some aggregates are produced, in order to prevent the quality of aggregates from being affected by external factors, aggregate silos are used for storage. During the storage of aggregates in the silos, samples of aggregates inside the silos are taken to test the physical and chemical properties of the aggregates to ensure that they meet the design and construction requirements.

[0003] When sampling in the aggregate silo, it is necessary to take samples from multiple points and mix them evenly to form a comprehensive sample. The aggregate samples after sampling are heavier. Since the aggregate silo is higher, the staff need to bring the aggregate samples to the ground after sampling. However, when the staff transport the samples up and down, the heavier aggregate samples are difficult to carry. In addition, the stairs of the aggregate silo are high and narrow, which is prone to accidents.

[0004] In summary, there is a need for a device that can assist workers in transporting aggregate samples. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0023] In order to solve the technical problems in the background technology, a lifting and sample feeding device is provided as follows:

[0024] Combination Figure 1-Figure 5 As shown, a lifting and sample feeding device provided by the utility model comprises a base 1, and lifting mechanisms 2 are arranged at both ends of the base 1. The lifting mechanism 2 can provide power for the lifting of the placing mechanism 3. A placing mechanism 3 for placing a sample container is arranged inside the lifting mechanism 2, and a protective mechanism 4 for protecting the sample container is arranged outside the placing mechanism 3. The protective mechanism 4 can avoid the safety hazard caused by the sample container falling. A sample pressing mechanism 5 for protecting the sample container is arranged inside the protective mechanism 4. The sample pressing mechanism 5 can fix and limit the position of the sample container. The placing mechanism 3 comprises a placing table 31, a supporting rod 32 and a spring 33. The placing table 31 is slidably connected to the lifting mechanism 2. A plurality of adjustment slots are opened inside the placing table 31, and the adjustment slots are arranged in an array. The support rod 32 is arranged in a row, and a support rod 32 is arranged inside the adjustment groove. A spring 33 is arranged at the bottom of the support rod 32. The spring 33 can assist the support rod 32 in lifting and resetting. The support rod 32 engages and slides with the adjustment groove. The support rod 32 and the spring 33 are arranged corresponding to the adjustment groove. The support rod 32 distributed in the array can slide with the adjustment groove and contact with the sample container. Then, it can drop according to the shape of the bottom of the sample container to form an area engaged with the sample container, thereby ensuring that the placement mechanism 3 can stably place the sample container and ensure that the sample can be stably transported during lifting and delivering. A buffer pad 11 is arranged on the top surface of the base 1. The buffer pad 11 has an elastic structure. The buffer pad 11 with an elastic structure can buffer and protect the placement mechanism 3 after it falls.

[0025] In this embodiment, the lifting mechanism 2 includes a lifting plate 21, a lifting box 22, a motor 23, a winding roller 24, a lifting rope 25 and a lifting block 26. The lifting plate 21 is fixedly arranged on the side of the base 1. The lifting box 22 is arranged on the top of the lifting plate 21. The motor 23 is arranged inside the lifting box 22. The output end of the motor 23 is provided with a winding roller 24. The outer side of the winding roller 24 is wound with a lifting rope 25. The end of the lifting rope 25 is provided with a lifting block 26. The lifting block 26 is fixedly connected to the side of the placement table 31. The motor 23 can retract and release the lifting rope 25 through the winding roller 24, drive the lifting block 26 together with the placement table 31 to rise and fall, thereby achieving the purpose of lifting and transporting the aggregate sample.

[0026] In this embodiment, a lifting groove is provided inside the lifting plate 21, and the lifting block 26 engages and slides with the lifting groove. The engagement and sliding of the lifting block 26 with the lifting groove can ensure that the placement mechanism 3 follows the lifting block 26 for stable lifting.

[0027] The implementation principle of the first embodiment is as follows: when the lifting and sample delivery device is used, the device is first fixedly installed on the side of the aggregate bin 6. After the staff takes samples, the container containing the aggregate sample is placed on the placement mechanism 3. At this time, the sample container will press down the support rods 32 distributed in the array. The support rods 32 will move downward in the adjustment groove under the pressure of the sample container and engage with the bottom of the sample container, thereby ensuring the stable placement of the sample container. Then, the motor 23 in the lifting mechanism 2 drives the winding roller 24 to wind up the lifting rope 25. At this time, the lifting block 26 will drive the placement mechanism 3 to descend together with the sample container, so as to achieve the purpose of safely transporting the aggregate sample. Example 2

[0028] like Figure 1-Figure 4 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0029] In order to further ensure the safety of aggregate samples during transportation, this embodiment provides the following design:

[0030] The protection mechanism 4 includes a vertical rod 41 and a horizontal rod 42. The vertical rod 41 is mirror-imaged and arranged outside the four corners of the placement table 31. The horizontal rod 42 is arranged between the vertical rods 41. There are multiple groups of horizontal rods 42 distributed at equal intervals vertically. The multiple horizontal rods 42 can protect the aggregate container from the edge of the placement table 31 to reduce the risk of the aggregate container falling.

[0031] In this embodiment, the sample pressing mechanism 5 includes a sample pressing plate 1 51, a sample pressing plate 2 52 and a movable rod 56. The sample pressing plate 1 51 and the sample pressing plate 2 52 are both arranged between the vertical rods 41. The movable rod 56 is arranged on the edge of the sample pressing plate 1 51 and the edge of the sample pressing plate 2 52. The vertical rod 41 has a movable groove 43 on the side. The movable rod 56 is engaged and slid with the movable groove 43. The engagement and sliding of the movable rod 56 and the movable groove 43 facilitate the adjustment of the height of the sample pressing mechanism 5, so that the sample pressing mechanism 5 can be fixedly covered on the sample container and the position of the sample container can be fixed under the action of gravity.

[0032] In this embodiment, a connecting plate 53 is provided on the side of the pressing plate 1 51, a magnetic plate 2 55 is provided on the top surface of the pressing plate 2 52, and a magnetic plate 1 54 is provided on the bottom surface of the connecting plate 53. The magnetic plate 1 54 and the magnetic plate 2 55 are arranged correspondingly. The magnetic plate 1 54 and the magnetic plate 2 55 can fix the pressing plate 1 51 and the pressing plate 2 52 when the pressing plate 1 51 and the pressing plate 2 52 are closed, so as to ensure that the pressing plate 1 51 and the pressing plate 2 52 can stably cover the sample container.

[0033] The implementation principle of the second embodiment is as follows: after the sample container is placed, the sample pressing plate 1 51 and the sample pressing plate 2 52 in the sample pressing mechanism 5 are covered on top of the sample container. At this time, the magnetic suction plate 1 54 on the bottom surface of the connecting plate 53 will contact and adsorb the magnetic suction plate 2 55 on the top surface of the sample pressing plate 2 52. In this way, the sample pressing plate 1 51 and the sample pressing plate 2 52 can cover the sample container to prevent the sample container from being skewed or the sample from spilling.
