Description

Technical Field

[0001] The utility model belongs to the field of rubber sand alluvial soft soil subgrade experiments, and particularly relates to a rubber sand transfer device and a rubber sand alluvial soft soil subgrade experiment system. Background Art

[0002] With the continuous increase in the number of automobiles in China, the problem of how to properly dispose of waste rubber tires has become increasingly severe. Making rubber into subgrade fillers is an effective way to solve this problem. When making rubber into subgrade fillers, rubber is usually made into rubber particles and then mixed with sand to make rubber sand. However, in actual construction, the content of rubber particles, the size of rubber particles, and the overall gradation of rubber and sand have different effects on the shear strength of the soft soil subgrade. Therefore, when making rubber sand, an experimental device is needed to simulate the influence of rubber sand on the shear strength of the soft soil subgrade during actual use.

[0003] In the prior art, when conducting a rubber sand simulation experiment, an experimenter usually puts the rubber sand to be tested into the accommodation cavity of the shear box and then conducts a shear strength experiment on the rubber sand. Although this method can achieve the shear strength experiment on the rubber sand to be tested, due to the loose characteristics of the rubber sand, when the experimenter puts the rubber sand, some rubber sand will scatter outside the accommodation cavity of the upper shear box. Therefore, after the experimenter puts most of the rubber sand into the upper shear box, the experimenter manually puts the rubber sand scattered outside the accommodation cavity of the upper shear box into the accommodation cavity again, which prolongs the preparation process of the shear test and increases the workload of the experimenter.

[0023] Please refer to all the following drawings. It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention. Therefore, they do not have technical essence. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this specification are only for the convenience of clear narration, and are not used to limit the scope for the implementation of the present invention. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope for the implementation of the present invention.

[0024] The following various embodiments are only for illustration. Combinations can be made between the various embodiments, and it is not limited to the content shown in the following single embodiment.

[0025] Please refer to Figure 1 and 2, the present utility model provides a rubber sand transfer device 10, which includes a first driving component 1, a mounting member 2, two relatively arranged first clamping members 3, a second clamping member 4 and a limiting component 5; the mounting member 2 is connected to the first driving component 1; one end of each of the two first clamping members 3 is provided with an arc-shaped clamping portion 31 for clamping the side surface of the rubber sand, and the other end is connected to the mounting member 2; one end of the second clamping member 4 is provided with a circular lifting portion 41 for connecting to the bottom of the rubber sand, and the other end is movably connected to the mounting member 2; the bottom of the arc-shaped clamping portion 31 and the bottom of the circular lifting portion 41 are used for connecting to the top surface of the shearing upper box 50; the first driving component 1 includes a fixing member 11; the limiting component 5 is arranged on the mounting member 2, and the limiting component 5 is connected to the second clamping member 4; the first driving component 1 is used to drive the mounting member 2 to move, so that the first clamping member 3 and the second clamping member 4 move towards or away from the shearing upper box 50; when the first driving component 1 drives the mounting member 2 to move towards the shearing upper box 50, the limiting component 5 is used to abut against the fixing member 11 to limit the maximum distance of the second clamping member 4 moving towards the shearing upper box 50.

[0026] Specifically, the arc-shaped clamping portions 31 of the two relatively arranged first clamping members 3 enclose a cylindrical structure for clamping the rubber sand, and the circular lifting portion 41 of the second clamping member 4 is arranged at the bottom of the cylindrical structure, so that the first clamping member 3 and the second clamping member 4 enclose a cylindrical groove 61 structure for accommodating the rubber sand. The mounting member 2 can be a plate-like structure. In this embodiment, the mounting member 2 is an L-shaped mounting plate. When in use, after the rubber sand is placed in the cylindrical groove 61 structure, the first driving component 1 drives the mounting member 2 to move towards the shearing upper box 50, and the bottom of the second clamping member 4 and the bottom of the first clamping member 3 contact the top surface of the shearing upper box 50; then as the first driving component 1 continues to move, the second limiting block 52 abuts against the first fixing member 11. At this time, the bottom surface of the clamping portion of the second clamping member 4 remains in contact with the top surface of the shearing upper box 50, and the bottom surface of the second clamping member 4 is not above the accommodating cavity. When the second driving component 7 continues to move, due to the limiting effect of the limiting component 5 on the second clamping member 4, the position of the second clamping member 4 relative to the shearing upper box 50 will not change. Therefore, the first driving component 1 can only drive the two first clamping members 3 to continue to move towards the shearing upper box 50, and drive the rubber sand towards the accommodating cavity, and finally make the rubber sand directly above the accommodating cavity. It can be understood that due to the material characteristics of the rubber sand, after the rubber sand loses the lifting force of the second clamping member 4 at the bottom, the bottom of the rubber sand gradually contacts the top surface of the shearing upper box 50. With the abutting effect of the clamping portion of the first clamping member 3 on the side surface of the rubber sand, the rubber sand can also be directly above the accommodating cavity.

[0027] Please refer to Figure 1, the limit assembly 5 includes a first limit block 51, a second limit block 52, a first guide member 53 and a first elastic member 54; the first limit block 51 and the first guide member 53 are arranged on the mounting member 2, and the second clamping member 4 is slidably connected to the first guide member 53; the second limit block 52 is arranged on the second clamping member 4; the second limit block 52 is used to abut against the fixing member 11; one end of the first elastic member 54 is connected to the first limit block 51, and the other end is connected to the second limit block 52. Specifically, the second clamping member 4 and the limit assembly 5 are arranged on the side of the mounting member 2 close to the detection platform 20, and the first clamping member 3 is arranged on the side of the mounting member 2 away from the detection platform 20. The first guide member 53 can be a guide rail, and of course, other guide structures for guiding the second clamping member 4 can also be used, which is not limited to this embodiment. The first elastic member 54 can be a spring, and of course, other elastic structures can also be used, which is not limited to this embodiment. The second limit block 52 may be a plate-like structure, one end of which is connected to the second clamping member 4, and the other end is used to abut against the fixing member 11. In use, when the second limit block 52 abuts against the fixing member 11, the first driving component 1 continues to drive the mounting member 2 to move in the direction close to the shearing upper box 50. Due to the action of the second limit block 52 and the first elastic member 54, the second clamping member 4 is fixed relative to the mounting member 2, and the first elastic member 54 is stretched. When the first driving component 1 drives the mounting member 2 to move in the direction away from the shearing upper box 50, due to the elastic force of the first elastic member 54, the second clamping member 4 is driven to slide along the first guide member 53, so that the second clamping member 4 returns to its original position, until the second limit block 52 is disengaged from the fixing member 11, and the first driving component 1 drives the first clamping member 3 and the second clamping member 4 to move in the direction away from the shearing upper box 50.

[0028] The side of the arc-shaped clamping part 31 of the first clamping member 3 is provided with an escape portion 311 for escaping the second clamping member 4. Specifically, the escape portion 311 is a notch provided at the bottom of the arc-shaped clamping part 31, and the shape of the notch is adapted to the shape of the second clamping part. The setting of the escape portion 311 enables the bottom of the first clamping member 3 and the bottom of the second clamping member 4 to contact the top surface of the shear upper box 50, and also provides an escape space for the second clamping member 4 to separate from the cylindrical structure formed by the two first clamping members 3.

[0029] See also Figure 1 , 3, in one embodiment, a closing assembly 6 for closing the avoidance portion 311 is further provided on the avoidance portion 311, and the second clamping member 4 is further configured to drive the closing assembly 6 to move, so that the closing assembly 6 opens or closes the avoidance portion 311. Specifically, the closing assembly 6 includes a groove 61 formed by inward depression at the bottom of the arc-shaped clamping portion 31, a plurality of second elastic members 62 disposed in the groove 61, and a plurality of closing members 63 for closing the avoidance portion 311; one end of the second elastic member 62 is connected to the bottom of the groove 61, and the other end is connected to the closing member 63; the closing members 63 and the second elastic members 62 are provided in one-to-one correspondence. The cross-section of the closing member 63 may be an arc-shaped structure adapted to the groove 61, one end of which extends into the groove 61 and is connected to the second elastic member 62, and the other end extends out of the groove 61 for closing the avoidance portion 311. A first guiding structure is provided at one end of the closing member 63 away from the second elastic member 62, and a second guiding structure is also provided on the second clamping member 4. The arrangement of the guiding structures facilitates the second clamping member 4 to drive the closing member 63 to move, so as to open the avoidance portion 311. The first guiding structure and the second guiding structure may be inclined guiding surfaces. The second elastic member 62 may be an elastic mechanism such as a spring. In this embodiment, the second elastic member 62 is a spring. It can be understood that during use, when the second clamping member 4 pushes the first clamping member 3 out by using the avoidance portion 311, the closing assembly 6 gradually closes the avoidance portion 311 due to the loss of the abutting action of the second clamping member 4, thereby preventing the rubber sand from falling outside the accommodating cavity through the avoidance portion 311.

[0030] Please refer to Figure 2, the first driving component 1 includes a first driving member 12, a first lead screw 13 and a second guiding member 14; the first driving member 12, the second guiding member 14 and the fixing member 11 are arranged on the detection platform 20; one end of the first lead screw 13 is connected to the first driving member 12, and the other end is connected to the fixing member 11; the mounting member 2 is connected to the first lead screw 13 and is slidably connected to the second guiding member 14. Specifically, the fixing member 11 can be a mounting plate for mounting the first lead screw 13, which is vertically mounted on the detection platform 20. The first lead screw 13 is rotatably connected to the fixing member 11, and a lead screw nut can be arranged on the mounting member 2, so that when the first driving member 12 drives the first lead screw 13 to rotate, the mounting member 2 can be driven to slide along the second guiding member 14 by means of the lead screw nut. In this embodiment, the first driving member 12 is a motor and the second guiding member 14 is a guide rail. Of course, the first driving member 12 and the second guiding member 14 can also be other structures, and this embodiment does not limit this. It can be understood that through the setting of the fixing member 11, on the one hand, it can cooperate with the first driving member 12 to position both ends of the first lead screw 13, ensuring that the installation position of the first lead screw 13 will not change. On the other hand, it is also used to abut against the second limiting block 52, so that the relative position between the second clamping member 4 and the mounting member 2 changes. In other implementation manners, there are two second guiding members 14, and one second guiding member 14 is arranged on each side of the second lead screw 72 to ensure the smooth movement of the third mounting member 2.

[0031] Please refer to Figure 2, the transfer device further includes a second driving assembly 7 for driving the two first clamping members 3 to move in opposite directions. Specifically, in this embodiment, the second driving assembly 7 includes a second driving member 71, a second lead screw 72, and a third guiding member 73; the second driving member 71 and the third guiding member 73 are disposed on the mounting member 2; the second lead screw 72 is connected to the second driving member 71, one end of which is connected to one of the first clamping members 3, and the other end is connected to the other first clamping member 3; the two first clamping members 3 are slidably connected to the third guiding member 73. The third guiding member 73 may be a guide rail, and the second driving member 71 may be a motor. A lead screw nut may be provided on the first clamping member 3. The second driving member 71 is disposed between the two first clamping members 3. When the second driving member 71 drives the second lead screw 72 to rotate, by the action of the lead screw nut, the first clamping member 3 slides along the second guiding member 14, so that the two first clamping members 3 move towards or away from each other. In use, the second driving assembly 7 is used to drive the two first clamping members 3 to move in opposite directions, which is convenient for the experimenter to remove the rubber sand from the transfer device after the experiment. On the other hand, during the experiment, the first clamping members 3 can also be moved away from each other to move the first clamping members 3 away from above the shear upper box 50. It can be understood that in order to achieve the movement of the two first clamping members 3 towards and away from each other, the thread directions at both ends of the second lead screw 72 are opposite. For example, the thread direction of the connection end of the second lead screw 72 with one of the first clamping members 3 is right-handed, and the thread direction of the connection end with the other first clamping member 3 is left-handed.

[0032] On the other hand, the present invention also provides an experimental system for a rubber sand alluvial soft soil subgrade, which includes the above-mentioned rubber sand transfer device 10.

[0033] Exemplarily, the experimental system may further include a detection platform 20, a detection module 30, a feeding module 40, a shear upper box 50, and a shear lower box 60; the rubber sand transfer device 10, the feeding module 40, and the detection module 30 are disposed on the detection platform 20; the shear lower box 60 is slidably connected to the detection platform 20; the shear upper box 50 is disposed on the shear lower box 60; the shear upper box 50 and the shear lower box 60 are provided with accommodation cavities for accommodating rubber sand; the rubber sand transfer device 10 is used to transfer the rubber sand above the accommodation cavity of the shear upper box 50; the feeding module 40 is used to push the rubber sand into the accommodation cavities of the shear upper box 50 and the shear lower box 60; the detection module 30 is used to drive the shear lower box 60 to move to detect the shear strength of the rubber sand.

[0034] Specifically, after transferring the rubber sand above the shearing upper box 50, the rubber sand is pushed into the receiving cavities of the shearing upper box 50 and the shearing lower box 60 by the feeding module 40. Then, the detection module 30 drives the shearing lower box 60 to slide along the detection platform 20, so that a detection element arranged on the detection module 30, such as an element for detecting the force received by the shearing lower box 60, can detect the shear strength of the rubber sand. After the detection is completed, the detection module 30 drives the shearing lower box 60 to reset. Then, the rubber sand in the shearing upper box 50 and the shearing lower box 60 is pushed out of the receiving cavity by the feeding module 40 and transferred to a position far away from the shearing upper box 50 by the rubber sand transfer device 10, thus completing the integration experiment steps.

[0035] It can be understood that the main protection point of the present utility model is a rubber sand transfer device. Therefore, the remaining structures of an experimental system for a rubber sand alluvial soft soil subgrade, such as the detection module, the feeding module, etc., are only for illustrative purposes.

[0036] In summary, the present utility model clamps the rubber sand by two oppositely arranged first clamping members 3 and a second clamping member 4 arranged at the bottoms of the two first clamping members 3, and the bottoms of the first clamping members 3 and the second clamping member 4 are in direct contact with the top surface of the shearing upper box 50, avoiding the rubber sand from scattering on the detection platform 20 or outside the receiving cavity during the transfer process. In addition, due to the action of the limiting component 5 and the fixing member 11, when the first clamping member 3 and the second clamping member 4 move above the shearing upper box 50, the second clamping member 4 moves backward relative to the mounting member 2, so that the second clamping member 4 is disconnected from the rubber sand, facilitating the subsequent feeding module 40 to push the rubber sand into the receiving cavity. Therefore, the present utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0037] The above embodiments are only used to illustrate the principle and effects of the present utility model, rather than to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
