The first feature "below", "below" and "below" the second feature include the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] like Figure 1-Figure 5 As shown, the present invention provides a lifting device, including a bracket 1, a support plate 2, a lifting assembly 5 and a pushing assembly. The support plate 2 is slidably connected to the bracket 1, and the support plate 2 is used to carry the coal sample bottle 100. The lifting assembly 5 is connected to the support plate 2, and the lifting assembly 5 can drive the support plate 2 to slide between the bottom end and the top end of the bracket 1. The pushing assembly is fixedly connected to the bracket 1, and the pushing assembly is arranged above the support plate 2. When the support plate 2 slides to the top end of the bracket 1, the pushing assembly can push the coal sample bottle 100 from the support plate 2. When lifting the coal sample bottle 100, the lifting assembly 5 lifts the support plate 2 to the top end of the bracket 1, and then the pushing assembly pushes the coal sample bottle 100 from the support plate 2. The lifting process steps are simple, and the working efficiency is improved.

[0032] Specifically, a linear guide 4 is fixedly connected to the bracket 1, and the linear guide 4 is arranged along the length direction of the bracket 1, and the support plate 2 is slidably connected to the linear guide 4. The lifting assembly 5 drives the support plate 2 to slide along the linear guide 4, further ensuring the reliability of the movement of the support plate 2. The lifting assembly 5 includes an actuating part 51 and a slider 53, one end of the slider 53 is slidably connected to the linear guide 4, and the other end of the slider 53 is fixedly connected to the support plate 2, so that the support plate 2 is slidably connected to the linear guide 4 through the slider 53. The actuating part 51 can drive the slider 53 to move on the linear guide 4, and the actuating part 51 and the slider 53 can be fixedly connected or movably connected. For example, when the actuating part 51 and the slider 53 are fixedly connected, the part where the actuating part 51 and the slider 53 are fixedly connected can move in a direction parallel to the linear guide 4, thereby driving the slider 53 to slide along the linear guide 4. It is understandable that, in order to prevent the motion error of the actuating portion 51 from causing the actuating portion 51 to apply an eccentric load to the slider 53, a movable joint may be provided between the actuating portion 51 and the slider 53, so that the actuating portion 51 and the slider 53 are movably connected, and the eccentric load on the slider 53 is offset by the movable joint. As the prior art in the art, the structure of the movable joint and the related connection method are not described in detail here.

[0033] Furthermore, if Figure 4-Figure 5 As shown, the actuating part 51 is configured as a rodless cylinder, the guide rod of the rodless cylinder is arranged parallel to the linear guide rail 4, and the piston of the rodless cylinder is movably sleeved on the guide rod and can slide along the guide rod. A clamping positioning member 52 is provided between the piston of the rodless cylinder and the slider 53, one end of the clamping positioning member 52 is fixedly connected to the piston, and the other end of the clamping positioning member 52 can be clamped with the slider 53. After the clamping positioning member 52 is clamped with the slider 53, there is still a certain gap between the slider 53 and the piston, so that the movable connection between the slider 53 and the piston is realized. At the same time, the piston can drive the slider 53 to slide on the linear guide rail 4 through the clamping positioning member 52, thereby driving the support plate 2 to slide, so as to lift the coal sample bottle 100.

[0034] It is understandable that, in this embodiment, the lifting assembly 5 uses a cylinder to drive the support plate 2, which is simple and fast, and improves the working efficiency. In addition, the structure is simple, occupies less space, is easy to produce and install, and reduces the production cost. In other embodiments, it can also be implemented by other forms of linear drive mechanisms, such as linear motors, threaded rod transmission pairs, gear racks, hydraulic cylinders or electromagnetic drives, etc. Those skilled in the art can modify the present embodiment in combination with relevant existing structures. It is impossible to list all the implementation methods here, so they will not be repeated.

[0035] Furthermore, the ejection assembly includes an ejection member 6 and a push plate 3, wherein the ejection member 6 is fixedly connected to the bracket 1, and the push plate 3 is connected to the output end of the ejection member 6, and the output end of the ejection member 6 can drive the push plate 3 to eject the coal sample bottle 100 from the support plate 2. The ejection member 6 is preferably a telescopic cylinder, and the telescopic direction of its output end is preferably perpendicular to the lifting direction of the coal sample bottle 100, that is, the telescopic direction of the output end of the ejection member 6 is perpendicular to the setting direction of the linear guide 4, so as to ensure that the coal sample bottle 100 is pushed to the desired position without causing the coal sample bottle 100 to fall or be damaged. In this embodiment, the bracket 1 is arranged in the vertical direction, so that the linear guide 4 is arranged in the vertical direction, the coal sample bottle 100 is lifted in the vertical direction, and the push plate 3 can push the coal sample bottle 100 in the horizontal direction. In possible actual application scenarios, for example, when space is limited and the bracket 1 cannot be set in the vertical direction, and can only be set at an angle to the vertical direction, the pushing direction of the push plate 3 is also adaptively adjusted to ensure that the thrust applied by the push plate 3 to the coal sample bottle 100 is consistent with the movement direction of the coal sample bottle 100.

[0036] Optionally, to reduce the risk of the coal sample bottle 100 falling off the support plate 2 during the lifting process, guard plates are provided on both sides of the support plate 2. At the same time, to ensure that the push plate 3 can effectively push the coal sample bottle 100 out, the length direction of the guard plate is parallel to the moving direction of the push plate 3, so that the support plate 2 can move effectively.

[0037] It is understandable that in this embodiment, the ejection assembly uses a cylinder to drive the push plate 3, which is simple and fast, and improves the working efficiency. In addition, the structure is simple, occupies less space, is easy to produce and install, and reduces the production cost. In other embodiments, it can also be implemented by other forms of linear drive mechanisms, such as linear motors, hydraulic motors, slewing bearings or electromagnetic drives, etc. Those skilled in the art can modify it based on this embodiment in combination with relevant existing structures. It is impossible to list all the implementation methods here, so they will not be repeated.

[0038] Furthermore, if Figure 1-Figure 2 As shown, in order to ensure the accuracy of the action of the lifting component 5 and the pushing component, it is ensured that the lifting component 5 lifts the coal sample bottle 100 into place and then the pushing component pushes the coal sample bottle 100 out. The lifting device also includes two detection components 7, and the two detection components 7 are respectively arranged at the bottom and top of the bracket 1. The lifting device has a first state and a second state. When the lifting device is in the first state, the lifting component 5 moves to the top of the bracket 1, that is, the coal sample bottle 100 is lifted into place, and at least part of the lifting component 5 overlaps with the detection component 7 at the top of the bracket 1. When the lifting device is in the second state, the lifting component 5 moves to the bottom end of the bracket 1, that is, the support plate 2 moves to the bottom end of the bracket 1 and can carry a new coal sample bottle 100, and at least part of the lifting component 5 overlaps with the detection component 7 at the bottom end of the bracket 1.

[0039] Specifically, Figure 4-Figure 5 As shown, the detection component 7 includes a mounting plate 71, a sensor 72 and a sensing sheet 73. The mounting plate 71 is fixedly connected to the bracket 1, and the sensor 72 is fixedly connected to the mounting plate 71. The sensing sheet 73 is fixedly connected to the lifting component 5. Specifically, the sensing sheet 73 is fixedly connected to the slider 53 of the lifting component 5. The sensor 72 is used to sense the sensing sheet 73. When the sensing sheet 73 slides to the relevant sensor 72 along with the slider 53, after the sensor 72 senses the sensing sheet 73, it indicates that the slider 53 slides to the top or bottom of the bracket 1, and the corresponding lifting device is in the first state or the second state, so as to facilitate the subsequent steps. The sensor 72 can be a proximity switch, a micro switch, a travel switch, a photoelectric switch or a diffuse reflection sensor. The relevant setting method and detection principle are the prior art in this field and will not be repeated here.

[0040] This embodiment provides a method for using a lifting device, which is applied to the lifting device in this embodiment. The method includes:

[0041] Step 1: Place the coal sample bottle 100 on the support plate 2;

[0042] Step 2: The lifting assembly 5 slides the support plate 2 from the bottom end of the bracket 1 to the top end of the bracket 1, and the detection assembly 7 located at the top end of the bracket 1 detects that the lifting device is in the first state;

[0043] Step 3: The lifting assembly 5 remains in position, and the pushing assembly pushes the coal sample bottle 100 from the support plate 2 to complete the loading of the coal sample bottle 100, and then the pushing assembly is reset;

[0044] Step 4: After the ejection assembly is reset, the lifting assembly 5 slides the support plate 2 from the top of the bracket 1 to the bottom of the bracket 1. The detection part located at the bottom of the bracket 1 detects that the lifting device is in the second state, and repeats step 1 to realize the cyclic lifting and loading of the coal sample bottle 100.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
