DETAILED DESCRIPTION

[0022] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0023] The following is combined with Figures 1 - 5 This embodiment is described in further detail.

[0024] like Figure 1 As shown, the tomographic scanning coal rock identification equipment in this embodiment includes a support system and a measurement system. The support system includes a base 100 and a tray assembly rotatably arranged on the base 100, and the tray assembly is used to support the coal rock sample 110; the measurement system includes a CT scanning device 130 arranged above the base 100 through a frame 101, wherein the CT scanning device 130 adopts the structure disclosed in the patent with publication number CN218470591U, which can scan and process the coal rock sample 110 rotating on the tray assembly, so as to observe the internal structure of the coal rock and the distribution of the components; wherein a motor for driving the tray assembly to rotate is arranged in the base 100, so that the coal rock sample 110 can obtain a more comprehensive scanning process.

[0025] Combination Figures 2 - 4 As shown, in this embodiment, the tray assembly includes a chassis 120, and the upper side surface of the chassis 120 is provided with a sliding groove 201 with a T-shaped cross-section along its radial direction. There are multiple sliding grooves 201 evenly distributed along the circumference of the chassis 120, and limit members for limiting the coal rock sample 110 are slidably provided in the sliding grooves 201. A rotating cavity 301 is provided in the chassis 120, and a driving assembly for synchronously driving the limit members to move closer to or away from each other is provided in the rotating cavity 301.

[0026] In actual use of this embodiment, the bottom end surface of the chassis 120 is fixedly connected to the output shaft of the motor, so that the chassis 120 can be driven to rotate by the motor;

[0027] Among them, the number of sliding grooves 201 is preferably set to 3, so that the driving component can synchronously drive the limiting member to slide along the corresponding sliding groove 201 so that they are close to each other, and the coal rock sample 110 placed on the chassis 120 can be limited, thereby better avoiding the coal rock sample 110 from tipping over when the chassis 120 rotates, thereby affecting the measurement result of the measurement system; when the driving component synchronously drives the limiting member to slide along the corresponding sliding groove 201 so that they are away from each other, the taking and placing of different coal rock samples 110 on the chassis 120 can be better realized, thereby improving the applicability of the tray assembly.

[0028] In this embodiment, a sliding groove 202 connecting to the rotating chamber 301 is provided on the bottom wall of the sliding groove 201 along its extension direction, and the limiting member includes a sliding block 210 slidably arranged in the sliding groove 201, and a protrusion 310 is provided on the lower side surface of the sliding block 210 and penetrates the sliding groove 202 and extends into the rotating chamber 301; the driving component includes a turntable 320 rotatably arranged in the rotating chamber 301, and the upper end surface of the turntable 320 is provided with planar spiral teeth with uniform spacing, and the lower side surface of the protrusion 310 is provided with a rack matching the teeth.

[0029] In this embodiment, a limit rod 211 bent toward the center of the bottom plate 120 is disposed on the upper side of the sliding block 210, and a limit block 212 for limiting the coal rock sample 110 is disposed at the end of the limit rod 211;

[0030] Among them, by setting the rotating disk 320, the tooth groove, the protrusion 310 and the rack, in actual use, the sliding block 210 is located in the sliding groove 201 and slides, so that the sliding block 210 is restricted. Therefore, by using the matching setting of the tooth groove and the rack, the rotating disk 320 rotates forward and reverse in the rotating cavity 301, and can synchronously drive the sliding block 210 to synchronously approach or move away from the corresponding sliding groove 201;

[0031] In actual use, the opening of the rotating cavity 301 is set downward, and a blocking plate 230 for installing the turntable 320 in the rotating cavity 301 is fixedly connected to the opening of the rotating cavity 301, thereby better realizing the installation of the turntable 320 in the chassis 120.

[0032] Combination Figure 5 As shown, in this embodiment, a toggle groove 203 connecting to the rotating chamber 301 is provided on the side wall of the chassis 120 along its circumference, and a toggle column 511 extending out of the toggle groove 203 is provided on the side wall of the turntable 320, and a fixing part for fixing the turntable 320 is provided on the protruding end of the toggle column 511.

[0033] With the structure in this embodiment, by toggling the toggle post 511 along the toggle slot 203, the forward and reverse rotation of the turntable 320 in the rotation cavity 301 can be preferably achieved. Furthermore, the operation of driving the limit member to approach or move away synchronously is simple and convenient, which is beneficial for use.

[0034] In its actual use, in order to prevent the mis-sliding of the toggle post 511 in the toggle slot 203, which may affect the operation of the limit member, the toggle post 511 can be fixed by a fixing member to prevent the turntable 320 from rotating due to the mis-sliding of the toggle post 511.

[0035] It should be noted that in order to install the turntable 320 in the rotation cavity 301, the toggle post 511 passes through the toggle slot 203 and is threadedly connected to the outer side wall of the turntable 320.

[0036] In this embodiment, positioning holes 204 are uniformly arranged along the circumferential direction of the outer side wall of the chassis 120 and are located above the toggle slot 203; the fixing member includes a fixing cylinder 220 sleeved on the protruding end of the toggle post 511. The end wall of the fixing cylinder 220 facing the chassis 120 extends outward to form a fitting portion 222. A positioning post 521 is provided on the fitting portion 222. An installation ring 530 that slides within the fixing cylinder 220 is provided on the protruding end of the toggle post 511. A spring 540 is sleeved on the toggle post 511 and is used to drive the fixing cylinder 220 to move towards the chassis 120 so that the positioning post 521 extends into the corresponding positioning hole 204.

[0037] In this embodiment, the shape of the fitting portion 222 fits the outer side wall of the chassis 120. Thus, under the action of the spring 540, the fixing cylinder 220 moves towards the chassis 120, driving the fitting portion 222 to fit the outer side wall of the chassis 120, enabling the positioning post 521 to extend into the corresponding positioning hole 204. Furthermore, the position of the fixing cylinder 220 is fixed. At this time, it is impossible to drive the toggle post 511 to slide along the toggle slot 203 by toggling the fixing cylinder 220, that is, the toggle post 511 is fixed and no mis-rotation will occur; when the fixing cylinder 220 is pulled outward, the positioning post 521 can be driven to extend out of the positioning hole 204, thereby releasing the fixation of the fixing cylinder 220. At this time, toggling the fixing cylinder 220 to drive the toggle post 511 to slide along the toggle slot 203 enables the rotation operation of the turntable 320, which is convenient for use.

[0038] In the actual use of this embodiment, the fixing cylinder 220 has a structure with one end open, and the opening is arranged towards the end away from the chassis 120. A plug plate 221 is threadedly connected to the opening. At the same time, a stepped groove for sleeving the installation ring 530 is provided at the protruding end of the toggle post 511, and a nut 550 for limiting the installation ring 530 within the stepped groove is threadedly connected in the stepped groove. Thus, the disassembly and assembly of the spring 540 and the installation ring 530 within the fixing cylinder 220 are preferably achieved.

[0039] In this embodiment, in order to prevent the fixed cylinder 220 from rotating when the fixed cylinder 220 is pulled, resulting in the positioning column 521 being unable to align with the positioning hole 204, a limiting groove 512 is provided on the outer wall of the driving column 511 along its axial direction, and a limiting block is provided at the end of the fixed cylinder 220 and extends into the limiting groove 512 for sliding. The limiting block extends into the limiting groove 512 and slides, so that the fixed cylinder 220 is restricted to prevent it from circumferential rotation and affecting the cooperation between the positioning column 521 and the positioning hole 204.

[0040] Working principle: Place the coal rock sample 110 at the center of the chassis 120, then pull the fixed cylinder 220 outward and move the fixed cylinder 220 to drive the moving column 511 to slide along the moving groove 203, drive the limiting parts to approach each other to limit the coal rock sample 110, then loosen the fixed cylinder 220 to allow the positioning column 521 to extend into the corresponding positioning hole 204, fix the moving column 511, then start the motor to drive the chassis 120 to rotate, and turn on the CT scanning device 130 to scan and process the coal rock sample 110.

[0041] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
