Description

Technical Field

[0001] This application relates to the technical field of experimental equipment, and more particularly, to a rock sample support device. Background Art

[0002] When conducting an experiment on measuring the thermal conductivity of a rock sample, during the experiment, a cylindrical probe connected with a surface sensor needs to be gently placed on a flat rock surface. This requires that at least one flat area of the sample is larger than the area of the surface sensor, and to ensure that there is no sliding between the circular probe and the contact surface of the sample, the rock sample is generally required to be made into a cylinder or a rectangular prism. However, due to the presence of a large number of joints and fractures in the rocks in some areas, especially coal rock samples, the rocks are prone to breakage during the production process and it is difficult to form a rock sample in the shape of a cylinder or a rectangular prism. This makes it difficult to conduct an experiment on measuring the thermal conductivity of rock samples with a large number of joints and fractures at present. Summary of the Invention

[0003] The purpose of this application is to provide a rock sample support device for at least one technical problem involved in the background art.

[0004] To achieve the above purpose, this application adopts the following technical solutions:

[0005] This application provides a rock sample support device, including a storage frame and at least three support components. The support component includes a telescopic support leg. One end of the support leg is a connection end movably connected to the storage frame, and the other end of the support leg is a support end. Each support leg is used to support the storage frame.

[0006] Optionally, it includes a plurality of support rods. The storage frame is a polygon, and at least some of the support rods are used to be detachably connected in sequence to form the storage frame.

[0007] The beneficial effect of this technical solution is that in this way, the appropriate number of support rods can be selected according to the size and shape of the rock sample, and a polygon that can sufficiently accommodate at least part of the rock sample can be formed, making the rock sample support device have good flexibility and applicability.

[0008] Optionally, the support rod includes a rod body, a first joint installed at one end of the rod body, and a second joint installed at the other end of the rod body. Among two adjacent support rods, the first joint of one support rod is detachably sleeved on the second joint of the other support rod.

[0009] The beneficial effect of this technical solution is that the first joint and the second joint are sleeved, which is convenient for the quick disassembly and assembly of two adjacent support rods.

[0010] Optionally, both the first joint and the second joint are cylindrical. The axial directions of the first joint and the second joint are both perpendicular to each of the support rods in the storage frame. The first joint is in the shape of a cylinder, and the first joint is sleeved outside the second joint.

[0011] Optionally, the support rod further includes a first hinge shaft. The axial direction of the first hinge shaft is parallel to the axial direction of the first joint. The first joint is hinged to one end of the rod body through the first hinge shaft.

[0012] The beneficial effect of this technical solution is as follows: In this way, the first joint can rotate relative to the rod body within a certain range. When the number of support rods forming the storage frame is changed, the angle of the first joint relative to the rod body also changes accordingly, so as to facilitate the formation of a polygon storage frame with corresponding number of sides by the support rods after the change in number.

[0013] Optionally, the support rod further includes a second hinge shaft. The axial direction of the second hinge shaft is parallel to the axial direction of the second joint. The second joint is hinged to the other end of the rod body through the second hinge shaft.

[0014] The beneficial effect of this technical solution is as follows: In this way, both the first joint and the second joint can rotate relative to the rod body within a certain range. When the number of support rods forming the storage frame is changed, the angles of the first joint and the second joint relative to the rod body can also change accordingly, so as to facilitate the formation of a polygon storage frame with corresponding number of sides by the support rods after the change in number.

[0015] Optionally, an opening is formed on the side wall of the first joint. The opening penetrates the first joint in the axial direction of the first joint. The opening is used to accommodate the second hinge shaft.

[0016] The beneficial effect of this technical solution is as follows: In this way, when adjusting the relative position of the first joint and the second joint in the axial direction of the first joint, the opening provides a clearance space for the second hinge shaft, enabling the adjustment of the relative position of the first joint and the second joint in the axial direction of the first joint to be realized. Furthermore, the top edges of the support rods can be adjusted to be in the same plane or almost in the same plane, or the top edges of the support rods can be adjusted to a relative position convenient for placing rock samples, improving the applicability of the rock sample support device to rock samples with different structures. At the same time, this hinged form using the first hinge shaft and the second hinge shaft also restricts the relative rotation of two adjacent support rods other than the rotation around the first hinge shaft and / or the second hinge shaft, making the deformation degree of the storage frame relatively controllable and reducing the inconvenience brought to the experimental operation by the deformation of the storage frame.

[0017] Optionally, the support assembly further includes a third hinge shaft. The connecting end is hinged to the storage frame through the third hinge shaft.

[0018] The beneficial effects of this technical solution are as follows: In this way, the support legs can rotate relative to the storage frame within a certain range, enabling the relative position between the storage frame and the support legs to adapt to the structure of the rock sample. At the same time, the relative rotation between the support legs and the storage frame is only limited to the rotation of the support legs relative to the storage frame around the third hinge axis, making the relative movement between the storage frame and the support legs relatively controllable and reducing the inconvenience brought to the experimental operation by the relative movement between the storage frame and the support legs.

[0019] Optionally, it includes a plurality of support rods. The storage frame is polygonal, and at least some of the support rods are used to be detachably connected in sequence to form the storage frame. The support rod includes a rod body, a first joint installed at one end of the rod body, and a second joint installed at the other end of the rod body. Among two adjacent support rods, the first joint of one support rod is detachably sleeved outside the second joint of the other support rod, and the connection end is hinged to the second joint through the third hinge axis.

[0020] The beneficial effects of this technical solution are as follows: In this way, the second joint becomes the connection node between two adjacent support rods and the connection node between the storage frame and the support legs. The connection nodes are relatively concentrated at the second joint, which is beneficial to reducing the number of intermediate connection components. At the same time, it also reduces the adverse effects on the functions of other components (such as support rods) when multiple connection nodes are scattered on other components (for example, support rods) (the connection nodes will occupy the positions on the support rods for placing rock samples).

[0021] Optionally, the support assembly further includes a support suction cup and a ball. The support end and the support suction cup are connected by a ball hinge.

[0022] The beneficial effects of this technical solution are as follows: Through the support suction cup, the support assembly can be fixed on a relatively flat plane by adsorption, making the rock sample support device as a whole not easy to move during the experiment and improving the stability of the rock sample support device for supporting the rock sample. And through the ball hinge, the position of the rock sample can be appropriately adjusted according to the relative position of the plane on the rock sample support for placing the thermal sensor probe, so that the thermal sensor probe can be placed on the rock sample relatively stably.

[0023] The technical solution provided by this application can achieve the following beneficial effects:

[0024] The rock sample support device provided by the present application restricts the relative positions of the placement frame and the rock sample by directly contacting the placement frame with the rock sample, and adjusts the levelness of the plane of the rock sample for placing the thermal sensor probe by adjusting the positional relationship between the placement frame and each support leg. Furthermore, the plane of the rock sample for placing the thermal sensor probe can stably place the thermal sensor probe. The plane of the rock sample for placing the thermal sensor probe may not need to be processed or only need a small amount of processing, and the rock sample does not need to be processed into a cylinder or a cube. Therefore, some rock samples with a large number of joints and fractures can also be used for thermal conductivity measurement experiments.

[0043] The technical solution of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0044] In the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0045] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0046] As Figures 1 to 6 shown, the present application provides a rock sample support device, including a storage frame 03 and at least three support components. The support component includes a telescopic support leg 04. One end of the support leg 04 is a connection end 14 movably connected to the storage frame 03, and the other end of the support leg 04 is a support end 15. Each support leg 04 is used to support the storage frame 03.

[0047] It is understandable that in order for the support leg 04 to support the storage frame 03, the movable connection between the support leg 04 and the storage frame 03 has a certain damping effect, and the telescoping of the support leg 04 also has a certain damping effect, or the two relatively movable parts of the support leg 04 are snap-fitted, and the telescoping of the support leg 04 is achieved by changing the snap-fitting position of these two parts; in order to achieve the telescoping of the support leg 04, the support leg 04 can include two tube structures sleeved together, or include a rod structure and a tube structure sleeved outside the rod structure; the positions where the support legs 04 are connected to the storage frame 03 are distributed at multiple places on the storage frame 03, and the positions where the support legs 04 are connected to the storage frame 03 are preferably evenly distributed on the storage frame 03.

[0048] When the rock sample support device provided in this application is in use, the rock sample 02 can be placed downward into the space enclosed by the storage frame 03, and the relative position between the storage frame 03 and the rock sample 02 is limited by the contact between the rock sample 02 and the storage frame 03, so that the plane of the rock sample 02 for placing the thermal sensor probe 01 is the top surface of the rock sample 02. If the top surface of the rock sample 02 is just parallel to the horizontal plane or approximately parallel to the horizontal plane when the rock sample 02 is placed on the storage frame 03, the thermal sensor probe 01 can be placed on the top surface of the rock sample 02 to start the experiment. If the top surface of the rock sample 02 is inclined greatly relative to the horizontal plane and the thermal sensor probe 01 cannot be placed when the rock sample 02 is placed on the storage frame 03, the position of the storage frame 03 can be adjusted by extending or shortening one or more of the support legs 04, and then the angle of the top surface of the rock sample 02 relative to the horizontal plane can be adjusted until the thermal sensor probe 01 can be stably placed on the top surface of the rock sample 02, and the experiment starts after the thermal sensor probe 01 is stably placed on the top surface of the rock sample 02. Of course, when the plane where the figure enclosed by the top edge of the storage frame 03 is parallel to the horizontal plane or approximately parallel to the horizontal plane, some rock samples 02 can also be directly placed across the storage frame 03 instead of being placed into the space enclosed by the storage frame 03.

[0049] The rock sample support device provided in this application restricts the relative position between the storage frame 03 and the rock sample 02 by the direct contact between the storage frame 03 and the rock sample 02, and adjusts the levelness of the plane of the rock sample 02 for placing the thermal sensor probe 01 by adjusting the positional relationship between the storage frame 03 and each support leg 04. Furthermore, the plane of the rock sample 02 for placing the thermal sensor probe 01 can stably place the thermal sensor probe 01, and the plane of the rock sample 02 for placing the thermal sensor probe 01 does not need to be processed or only needs a small amount of processing, and the rock sample 02 does not need to be processed into a cylinder or a cube. Furthermore, some rock samples with a large number of joints and fissures can also conduct thermal conductivity measurement experiments.

[0050] Optionally, the rock sample support device provided by the embodiments of the present application includes a plurality of support rods. The storage frame 03 is polygonal, and at least some of the support rods are used to be detachably connected in sequence to form the storage frame 03. That is to say, all the support rods can be used to make a polygonal frame, or only some of the support rods can be selected to make a polygonal frame. In the embodiments of the present application, the polygonal frame can be formed by 3 to 10 sides. That is to say, in the embodiments of the present application, there can be 3 to 10 support rods. At least 3 support rods can be selected to make a triangular frame. The polygonal frame is preferably a quadrilateral, a hexagon or an octagon; the polygon is preferably a regular polygon. In this way, the appropriate number of support rods can be selected according to the size and shape of the rock sample 02 to form a polygon that can sufficiently accommodate at least part of the rock sample 02, so that the rock sample support device has good flexibility and applicability.

[0051] Optionally, the support rod includes a rod body 06, a first joint 07 installed at one end of the rod body 06, and a second joint 12 installed at the other end of the rod body 06. Among two adjacent support rods, the first joint 07 of one support rod is detachably sleeved on the second joint 12 of the other support rod. It can be understood that in order to enable each support rod to be connected into a polygonal frame, the two first joints 07 of two adjacent support rods cannot be connected to the two second joints 12 in a one-to-one correspondence. The first joint 07 and the second joint 12 are sleeved, which is convenient for the quick disassembly and assembly of two adjacent support rods. Of course, in addition to sleeving, the connection form of plugging or clamping can also be adopted between the adjacent first joint 07 and the second joint 12.

[0052] Optionally, both the first joint 07 and the second joint 12 are cylindrical. The axial direction of the first joint 07 and the axial direction of the second joint 12 are both perpendicular to each support rod in the storage frame 03. The first joint 07 is in a cylindrical shape, and the first joint 07 is sleeved outside the second joint 12. Of course, the first joint 07 can also be in a circular ring shape.

[0053] Optionally, the support rod further includes a first hinge shaft 11. The axial direction of the first hinge shaft 11 is parallel to the axial direction of the first joint 07. The first joint 07 is hinged to one end of the rod body 06 through the first hinge shaft 11. In this way, the first joint 07 can rotate relative to the rod body 06 within a certain range. When the number of support rods forming the storage frame 03 is changed, the angle of the first joint 07 relative to the rod body 06 also changes accordingly, so as to facilitate the formation of a polygonal storage frame 03 with corresponding number of sides by the support rods after the number change. Of course, the first joint 07 can also be fixedly connected to the rod body 06.

[0054] Optionally, the support rod further includes a second hinge shaft 13, the axial direction of the second hinge shaft 13 is parallel to the axial direction of the second joint 12, and the second joint 12 is hinged to the other end of the rod body 06 through the second hinge shaft 13. In this way, both the first joint 07 and the second joint 12 can rotate relative to the rod body 06 within a certain range. When the number of support rods forming the storage frame 03 is changed, the angles of the first joint 07 and the second joint 12 relative to the rod body 06 can also be changed accordingly, so as to facilitate the formation of a polygonal storage frame 03 with corresponding number of sides by the support rods after the number change. Of course, the second joint 12 can also be fixedly connected to the rod body 06.

[0055] Optionally, an opening 17 is formed on the side wall of the first joint 07, and the opening 17 penetrates the first joint 07 in the axial direction of the first joint 07, and the opening 17 is used to accommodate the second hinge shaft 13. In this way, when adjusting the relative position of the first joint 07 and the second joint 12 in the axial direction of the first joint 07, the opening 17 provides an avoidance space for the second hinge shaft 13, enabling the adjustment of the relative position of the first joint 07 and the second joint 12 in the axial direction of the first joint 07 to be realized. Furthermore, the top edges of the support rods can be adjusted to be in the same plane or almost in the same plane, or the top edges of the support rods can be adjusted to a relative position convenient for placing the rock sample 02, improving the applicability of the rock sample support device to rock samples 02 with different structures; at the same time, this hinged form using the first hinge shaft 11 and the second hinge shaft 13 also restricts the relative rotation of two adjacent support rods other than the rotation around the first hinge shaft 11 and / or the second hinge shaft 13, making the deformation degree of the storage frame 03 relatively controllable and reducing the inconvenience brought to the experimental operation by the deformation of the storage frame 03. Of course, the opening 17 can also be an opening that does not penetrate the first joint 07.

[0056] Optionally, the support assembly further includes a third hinge shaft 09, and the connection end 14 is hinged to the storage frame 03 through the third hinge shaft 09. In this way, the support leg 04 can rotate relative to the storage frame 03 within a certain range, enabling the relative position between the storage frame 03 and the support leg 04 to adapt to the structure of the rock sample 02. At the same time, the relative rotation between the support leg 04 and the storage frame 03 is only restricted to the rotation of the support leg 04 relative to the storage frame 03 around the third hinge shaft 09, making the relative movement between the storage frame 03 and the support leg 04 relatively controllable and reducing the inconvenience brought to the experimental operation by the relative movement between the storage frame 03 and the support leg 04. In the embodiment of the present application, preferably, the support assembly further includes a reinforcement gasket 08 and a larger gasket 10. The larger gasket 10 is fixed to the connection end 14 of the support leg 04, and the fixing gasket is fixed to the storage frame 03 (preferably, the reinforcement gasket 08 is fixed to the second joint 12), and the larger gasket 10 and the reinforcement gasket 08 are hinged through the third hinge shaft 09.

[0057] Optionally, the rock sample support device provided by the embodiments of the present application includes a plurality of support rods. The storage frame 03 is a polygon, and at least some of the support rods are used to be detachably connected in sequence to form the storage frame 03. The support rod includes a rod body 06, a first joint 07 installed at one end of the rod body 06, and a second joint 12 installed at the other end of the rod body 06. Among two adjacent support rods, the first joint 07 of one support rod is detachably sleeved outside the second joint 12 of the other support rod, and the connecting end 14 is hinged to the second joint 12 through the third hinge shaft 09. In this way, the second joint 12 becomes the connection node between two adjacent support rods and the connection node between the storage frame 03 and the support leg 04. The connection nodes are relatively concentrated at the second joint 12, which is beneficial to reducing the number of intermediate connection components. At the same time, when multiple connection nodes are dispersed on other components (such as support rods), the adverse effects on the functions of other components (the connection nodes will occupy the positions on the support rods for placing the rock sample 02) are also reduced. In the embodiments of the present application, when the storage frame 03 is a polygon frame with an even number of sides and the storage frame 03 has more than six sides, a support assembly can be set at every other second joint 12, that is to say, a support assembly can be set at every other two support rods.

[0058] Optionally, the support assembly further includes a support suction cup 05 and a ball 16. The support end 15 and the support suction cup 05 are ball-jointed through the ball 16. The support assembly can be fixed on a relatively flat plane through the adsorption of the support suction cup 05, so that the rock sample support device is not easy to move as a whole during the experiment, improving the stability of the rock sample support device for supporting the rock sample 02. And through the ball joint, the position of the rock sample 02 can be appropriately adjusted according to the relative position of the plane for placing the thermal sensor probe 01 on the rock sample support, so that the thermal sensor probe 01 can be placed on the rock sample 02 relatively stably.

[0059] To better illustrate the rock sample support device provided by the present application, the present application also provides an application example of the rock sample support device. In this application example, the rod body can also be called a transverse rod, the first hinge shaft, the second hinge shaft, and the third hinge shaft can all be called connection shafts, the first joint can also be called a buckle housing, the second joint can also be called a buckle inner cavity, the support leg can also be called a telescopic rod, and the support suction cup can also be called a suction cup. The specific application example is as follows:

[0060] The present invention relates to the field of sample testing, and the core theme is to use a bracket to assist the sample to maintain stability.

[0061] Specific application scenario: When conducting an experiment on measuring the thermal conductivity of a rock sample, during the experiment, a cylindrical probe with a surface sensor needs to be gently placed on a flat rock surface. The samples collected from the field rarely have flat surfaces, and due to the large number of joints and fractures in the rocks in some areas, the rocks are prone to breaking during the production of samples with flat surfaces.

[0062] It is difficult to ensure that when the circular probe is placed on the flat surface, the probe and the sample do not slip. This requires a bracket to assist in keeping the sample and the probe stable.

[0063] The measurement of the thermal conductivity of a rock sample is carried out by giving the sample a thermal stimulus and analyzing its response to temperature. The thermal stimulus is directly in contact with the sample to be measured through a thermal sensor. When the sample to be measured is a rock sample, the thermal sensor is a planar surface sensor. According to the industry standard DZ / T 0276.14 - 2015 Rock Thermal Conductivity Test, during the experiment, a cylindrical probe with a surface sensor needs to be gently placed on a flat rock surface. This requires that at least one flat surface area of the sample is larger than the area of the surface sensor, and to ensure that there is no slip on the contact surface between the circular probe and the sample, the rock sample is generally required to be made into a cylinder or a rectangular prism. Due to the large number of joints and fractures in the rocks in some areas, especially coal rock samples, the rocks are prone to breaking during the production process and it is difficult to form rock samples in the shape of a cylinder or a rectangular prism. If we have a bracket that can ensure that when the circular probe is placed on the flat surface, the probe and the sample do not slip, this solves the problem that natural rock samples are prone to breaking themselves and enables the smooth progress of the thermal conductivity measurement experiment.

[0064] According to the sample size, select the number of cross bars; connect the cross bars through buckles; adjust the length of the telescopic rod to ensure that when the suction cup adheres to the ground, the plane formed by the cross bars is basically parallel to the ground; place the flat surface of the sample on the bracket, and the rock mass is fixed to the bracket through the cross bars and the telescopic rod; if it is not stable, first adjust the length of the telescopic rod, and if stability still cannot be achieved, adjust the number of cross bars and readjust.

[0065] The stable support for rock sample testing includes cross bars, buckles for connecting the cross bars, a connecting shaft connected to a buckle housing, the connecting shaft connecting the inner cavity of the buckle, and the inner cavity of the buckle being placed inside the buckle housing to enable the connection of each cross bar. Every other buckle is connected to a telescopic rod, and the connection between the buckle and the telescopic rod is through a reinforcing gasket, a lower connecting shaft, and a larger gasket. The telescopic rod contacts the ground through balls and a suction cup.

[0066] The cross bars and buckles are made of non - heat - conducting materials, wear - resistant, and corrosion - resistant;

[0067] The telescopic rod is made of metal and can be telescoped in the middle;

[0068] The balls are made of metal and have a smooth spherical surface;

[0069] The suction cup is made of high-temperature resistant rubber material.

[0070] The specific implementation manner of the present invention is as follows:

[0071] Step 1: According to the size of the sample, select the number of cross bars, and the number of cross bars can be selected as 4, 6, or 8;

[0072] Step 2: Connect the cross bars through buckles;

[0073] Step 3: Adjust the length of the telescopic rod to ensure that when the suction cup sucks on the ground, the plane formed by the cross bars is basically parallel to the ground;

[0074] Step 4: Place the flat surface of the sample on the bracket, and the rock mass is fixed to the bracket through the cross bars and the telescopic rod;

[0075] Step 5: If it is unstable, first adjust the length of the telescopic rod. If stability still cannot be achieved, adjust the number of cross bars and start from Step 1 again.

[0076] From a functional perspective, the bracket is used to assist the sample to achieve stability during the test. The detachable cross bars and telescopic rods are suitable for samples of different styles and sizes. The technical solution of this application can also refer to the industry standard DZ / T 0276.14-2015 and the instruction manual of the ISOMET 2114 portable thermal property analyzer.

[0077] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of this application.
