Description

Technical Field

[0001] The present invention relates to the technical field of sample assembly equipment, and in particular to a unidirectional large-size sample assembly equipment and a method for using the unidirectional large-size sample assembly equipment. Background Art

[0002] Size effects are ubiquitous in rock and soil mechanics. To better understand their impact on mechanical properties, it's necessary to test specimens over a wide range of sizes, which require assembly before testing. For extremely long specimens, assembling them according to specific requirements is challenging because they often contain internal cracks. The bending and torque during installation can cause specimen fractures. Using overhead cranes is difficult to meet these requirements and poses significant safety risks. Existing equipment for installing products generally doesn't address the issue of overly long and fragile products, as exemplified by patents 201721172311.1, 201920813477.X, and 201310201247.5. Patent 202011430711.4 discloses a multi-scale specimen lifting and flipping device with continuously and steplessly adjustable width, and provides a specimen assembly device with a large length. It is effective for loading and installing hard rock samples, but for specimens with internal cracks or prefabricated cracks, grabbing at both ends will cause the middle of the specimen to break. This is related to the torque generated by the deviation in synchronization of flipping the specimen and the influence of the gravity of the specimen itself. Offsetting the flipping torque and supporting the specimen at multiple locations along the length direction can ensure the safety of the specimen and the operator, and the convenience of transporting the specimen before and after assembly is also an important consideration. Therefore, the development of a unidirectional large-scale geotechnical specimen assembly device for internal defects is very meaningful for studying the size effect. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems in the prior art of easy breakage of large-scale specimens during assembly, complicated process and great safety risks of manual operation.

[0004] The solution of the present invention is to provide a one-way large-size sample assembly device, which includes a turning mechanism placed on the front side and a conveying mechanism placed on the rear side;

[0005] The turning mechanism includes a rotating drum, a rotating drive assembly, a clamping unit and a fixed base. The rotating drum is connected to the base with a front-to-back axis as the axis. The rotating drive assembly is installed on the base and acts on the rotating drum to drive the rotation of the rotating drum. A working chamber is provided in the rotating drum, and the working chamber has an entrance and exit that pass through the rear end surface of the rotating drum. The upper wall and the lower wall of the working chamber are respectively provided with first guide rails arranged along the front-to-back direction, and the two first guide rails are symmetrically distributed with the axis of the rotating drum as the center.

[0006] The left and right sides of the working chamber are respectively provided with corresponding clamping devices, and the clamping devices include a clamping platform, a bracket, a first linear drive member and a second linear drive member, and the first linear drive member and the second linear drive member are both arranged in the left and right directions, and the clamping platforms of the clamping devices on the left and right sides are driven by the corresponding first linear drive members to approach or separate from each other, and the brackets of the clamping devices on the left and right sides are driven by the corresponding second linear drive members to approach or separate from each other, and the brackets include an upper supporting plate located above the clamping platform and a lower supporting plate located below the clamping platform, and the upper supporting plate and the lower supporting plate are respectively used to abut against the upper side and the lower side of the sample to achieve limiting, and the rotating drum is provided with a height adjustment drive assembly for driving the clamping devices to rise and fall;

[0007] The conveying mechanism includes a material receiving platform for receiving samples and a fixed conveying frame. The conveying frame is provided with a second guide rail arranged along the front-to-back direction. The second guide rail and the first guide rail of the lower wall of the working chamber are docked with each other. The material receiving platform is used to slide along the second guide rail from the entrance and exit to the working chamber, and then slide along the first guide rail of the lower wall of the working chamber to between the clamps on the left and right sides.

[0008] The above scheme receives the sample through the receiving platform of the conveying mechanism, and the receiving platform realizes the function of sending the sample into or out of the working chamber by moving between the second guide rail and the first guide rail on the lower wall of the working chamber. The operation is simple and convenient, and the adjustment and calibration of the position of the sample can be achieved by changing the position of the receiving platform relative to the first guide rail, thereby ensuring the accuracy of the sample assembly; and by arranging clamps on the left and right sides of the working chamber respectively, the clamping platforms of the clamps on the left and right sides are driven by the corresponding first linear drive members to achieve clamping of the side walls of the sample in the working chamber, and the brackets of the clamps on the left and right sides Driven by the corresponding second linear drive member, the upper support plate and the lower support plate are respectively abutted against the upper and lower sides of the sample to achieve the limitation of the sample and further support. Therefore, regardless of whether the sample has defects, the clamper can effectively clamp the sample with good clamping stability, effectively avoiding the problem of sample breakage and damage. At the same time, by raising the drive component to drive the clamper to rise and fall, and by rotating the drive component to drive the drum to flip, the posture of the sample clamped by the clamper is stably adjusted, which facilitates the reliable assembly of the sample, effectively improves work efficiency, does not require manual intervention, and has good safety.

[0009] In an improved solution, the clamper also includes a bracket, which is connected to the output end of the height adjustment drive assembly, and the upper support plate and the lower support plate are respectively slidably connected to the upper side wall and the lower side wall of the bracket, and the bracket also includes a receiving plate connecting the upper support plate and the lower support plate, and the second linear drive member is connected to the middle part of the height direction of the bracket, and the output end of the second linear drive member is connected to the receiving plate. By sliding the upper support plate and the lower support plate to the upper side wall and the lower side wall of the bracket respectively, it is ensured that the bracket can move left and right more stably under the drive of the second linear drive member.

[0010] In an improved solution, the first linear drive member is connected to the middle of the bracket in the height direction, and the output end of the first linear drive member is connected to the clamping platform, thereby achieving a more stable clamping effect of the clamping platform on the left and right walls of the sample.

[0011] In an improved solution, the height-adjusting drive assembly includes a height-adjusting motor, two lifting platforms, two sets of height-adjusting screw rods and two sets of height-adjusting guide rails, the two sets of height-adjusting guide rails are respectively vertically arranged on the left and right sides of the working chamber, the two lifting platforms are respectively slidably connected to the left and right height-adjusting guide rails, the two sets of height-adjusting screw rods are respectively vertically rotatably connected to the left and right sides of the working chamber, the two lifting platforms are both provided with vertical height-adjusting screw holes, the two lifting platforms are respectively screwed with the two sets of height-adjusting screw rods through the height-adjusting screw holes, the output end of the height-adjusting motor acts on the two sets of height-adjusting screw rods to drive the rotation, and the clamp is arranged on the opposite sides of the two lifting platforms, so that the height of the lifting platform is accurately controlled by the height-adjusting motor combined with the height-adjusting screw rod, and the operation is stable, reliable and high in precision.

[0012] In an improved solution, there are at least two clamps on each lifting platform and they are arranged at intervals from front to back, with the clamps on the left and right corresponding to each other, so that stable clamping of long specimens can be achieved through multiple clamps. In addition, during the turning process of the rotating drum or the raising and lowering process of the lifting platform, the clamping effect of all clamps on the specimen remains basically consistent, avoiding the situation where the specimen is broken due to torque generated by inconsistent forces at both ends.

[0013] In an improved solution, the lifting platform is provided with a positioning drive assembly, which includes a positioning motor, a positioning screw and a positioning guide rail. The positioning screw is rotatably connected to the lifting platform with the front and rear directions as the axis, and the positioning guide rail is arranged on the lifting platform from front to back. At least one clamp is slidably connected to the positioning guide rail and the clamp is provided with a positioning screw hole in the front and rear directions. The positioning screw hole is threadedly engaged with the positioning screw, and the output end of the positioning motor acts on the two positioning screws to drive the rotation, so that the position of the clamp slidably connected to the positioning guide rail is accurately controlled by the positioning motor in combination with the positioning screw, and the distance between the clamp set on the positioning guide rail and the clamp not set on the positioning guide rail is adjusted to achieve adaptation to samples of different lengths.

[0014] In an improved solution, the rotary drive mechanism includes a flip drive motor, a transmission gear set and a driven ring gear. The output end of the flip drive motor is connected to the transmission gear set. The driven ring gear is connected to the rotating drum and is coaxial with each other. The outer peripheral side of the driven ring gear is provided with gear teeth. The gear teeth of the driven ring gear are engaged with the transmission gear set, thereby realizing the precise control of the flip angle of the rotating drum by the rotary drive mechanism.

[0015] In an improved solution, the front and rear parts of the upper end surface of the base are provided with concave arc structures, and the front and rear parts of the outer peripheral wall of the rotating drum are respectively rotatably matched to the concave arc structures of the front and rear parts of the base; there are two driven gear rings and they are respectively connected to the front end surface and the rear end surface of the rotating drum, and there are two groups of transmission gear sets and they are respectively arranged at the front and rear parts of the base, and the gear teeth of the two driven gear rings are respectively meshed with the two groups of transmission gear sets, and the output end of the flipping drive motor is connected to the two groups of transmission gear sets, and the front and rear sides of the base are provided with upwardly protruding limit rods, and the limit rods are provided with a first roller that can rotate and abut against the inner peripheral side of the corresponding driven gear ring and a second roller that can rotate and abut against the outer peripheral wall of the rotating drum, so that the rotating drum can be rotated with the base through the concave arc structure, and the first roller and the second roller of the limit rod are used by the base to limit the position of the rotating drum during flipping, thereby ensuring the stability of the rotating drum during flipping.

[0016] The present invention also provides a method for using the unidirectional large-size sample assembly device, which is applied to the unidirectional large-size sample assembly device described above, and includes the following steps:

[0017] S1. In the initial state, the material receiving platform is located on the second guide rail of the conveyor frame. The first specimen is transported to the material receiving platform and placed there. The material receiving platform is then pushed forward so that the material receiving platform moves from the second guide rail to the corresponding position of the first guide rail on the lower wall of the working chamber. At this time, the first specimen on the material receiving platform is located between the left and right clamps.

[0018] S2. Adjust the drive assembly to move the clamp up and down so that the clamp is at the right height for the first sample.

[0019] S3. The first linear drive member of at least one clamping device drives the corresponding clamping platform to move toward the first sample until the first sample is clamped between the clamping platforms of the two corresponding clamping devices. The drive assembly is then raised to drive the clamping device to lift the sample off the material support platform. The second linear drives of the two corresponding clamping devices then drive the corresponding brackets toward each other so that the upper and lower brackets respectively abut against the upper and lower sides of the first sample to achieve position limiting. The material support platform is then pushed backward to return to the second guide rail.

[0020] S4. The rotary drive assembly drives the rotating drum to rotate 180° around its own axis, and the drive assembly is adjusted to drive the clamping device to rise and fall so that there is enough space under the first sample. At this time, the other sample is transported to the material receiving table for placement. Then, the material receiving table is pushed forward so that the material receiving table moves from the second guide rail to the first guide rail on the lower wall of the working chamber. At this time, the other sample on the material receiving table is located below the first sample. Then, the height drive assembly is adjusted to drive the clamping device to descend until the first sample and the other sample are fitted together and assembled.

[0021] S5. Push the material receiving platform backward to return it to the second guide rail, so that the two assembled specimens are separated from the working chamber.

[0022] The above scheme realizes the function of sending the sample into or out of the working chamber through the material receiving table, and in step S4, the adjustment and calibration of the sample position can be realized by changing the position of the material receiving table relative to the first guide rail, thereby ensuring the accuracy of the sample during assembly; and by first relying on the first linear drive member to drive the clamping table to clamp the sample, and then relying on the second linear drive member to drive the upper and lower support plates of the bracket to limit the upper and lower sides of the sample, the clamping device can achieve a stable and reliable clamping function of the sample. Subsequently, in step S4, the rotating drive component drives the rotating drum to flip 180° around its own axis, and then the other sample can be sent into the working chamber by the material receiving table, and then by adjusting the height of the clamping device by raising the drive component, efficient assembly operation between the two samples can be realized; compared with the existing technology, the above scheme has good protection for the sample, high assembly efficiency and assembly accuracy, and no manual operation is required, and good safety.

[0023] In an improved solution, in step S2, the height adjustment drive assembly drives the clamp to rise and fall so that the clamp is adapted to the height of the first sample, and the positioning motor of the position adjustment drive assembly controls the position of the clamp slidably connected to the positioning guide rail through the positioning screw, so that the spacing between the clamps on the same lifting platform is adapted to the length of the first sample.

[0038] See also Figure 1-Figure 7 , an embodiment of the present invention provides a one-way large-size sample assembly device, comprising a turning mechanism disposed at the front side and a conveying mechanism disposed at the rear side;

[0039] The turning mechanism includes a rotating drum 2, a rotary drive assembly 3, a clamping unit, and a fixed base 1. The rotating drum 2 is connected to the base 1 with the axis in the forward and backward direction as the axis. The rotary drive assembly 3 is installed on the base 1 and acts on the rotating drum 2 to drive the rotation of the rotating drum 2. The rotating drum 2 is provided with a working chamber 21, and the working chamber 21 has an entrance 22 extending to the rear end surface of the rotating drum 2. The upper and lower walls of the working chamber 21 are respectively provided with first guide rails 23 arranged in the forward and backward direction, and the two first guide rails 23 are symmetrically distributed with the axis of the rotating drum 2 as the center.

[0040] The left and right sides of the working chamber 21 are respectively provided with corresponding clamps 4, and the clamps 4 include a clamping platform 41, a bracket 42, a first linear drive member 43 and a second linear drive member 44. The first linear drive member 43 and the second linear drive member 44 are both arranged in the left and right directions. The clamping platforms 41 of the clamps 4 on the left and right sides are driven by the corresponding first linear drive members 43 to approach or separate from each other, and the brackets 42 of the clamps 4 on the left and right sides are driven by the corresponding second linear drive members 44 to approach or separate from each other. The bracket 42 includes an upper support plate 421 located above the clamping platform 41 and a lower support plate 422 located below the clamping platform 41. The upper support plate 421 and the lower support plate 422 are respectively used to abut against the upper side and the lower side of the sample to achieve limiting. The rotating drum 2 is provided with a height adjustment drive assembly 5 for driving the clamps 4 to rise and fall;

[0041] The conveying mechanism includes a receiving platform 7 for receiving the sample and a fixed conveying frame 6. The conveying frame 6 is provided with a second guide rail 61 arranged along the front and rear direction. The second guide rail 61 and the first guide rail 23 of the lower wall of the working chamber 21 are connected to each other. The receiving platform 7 is used to slide along the second guide rail 61 from the entrance and exit 22 to the working chamber 21, and then slide along the first guide rail 23 of the lower wall of the working chamber 21 to between the clamps 4 on the left and right sides.

[0042] The above scheme receives the sample through the material receiving platform 7 of the conveying mechanism, and the material receiving platform 7 moves between the second guide rail 61 and the first guide rail 23 on the lower wall of the working chamber 21 to realize the function of sending the sample into or out of the working chamber 21. The operation is simple and convenient, and the position of the sample can be adjusted and calibrated by changing the position of the material receiving platform 7 relative to the first guide rail 23, thereby ensuring the accuracy of the sample assembly; and by arranging the clamping device 4 on the left and right sides of the working chamber 21 respectively, the clamping platform 41 of the clamping device 4 on the left and right sides is driven by the corresponding first linear drive member 43 to realize the clamping of the side wall of the sample in the working chamber 21, and the clamping device on the left and right sides The bracket 42 of 4 is driven by the corresponding second linear drive member 44, so that the upper support plate 421 and the lower support plate 422 are respectively in contact with the upper and lower sides of the sample to achieve the limiting and further supporting effect of the sample, so that regardless of whether the sample has defects, the clamping device 4 can effectively clamp the sample with good clamping stability, effectively avoiding the problem of sample breakage and damage; at the same time, by raising the driving component 5 to drive the clamping device 4 to rise and fall, and by rotating the driving component 3 to drive the turning of the drum 2, the posture of the sample clamped by the clamping device 4 is stably adjusted, which facilitates the reliable assembly of the sample, effectively improves work efficiency, does not require manual participation, and has good safety.

The second linear drive member 44 is connected to the middle portion of the height direction of the bracket 45, and the output end of the second linear drive member 44 is connected to the receiving plate 423. By slidingly connecting the upper and lower support plates 421 and 422 to the upper and lower side walls of the bracket 45, respectively, the bracket 42 can be driven by the second linear drive member 44 to more stably move left and right. The second linear drive member 44 can be an electric cylinder, an oil cylinder, or a pneumatic cylinder. The output end of the second linear drive member 44 of the clamper 4 on the left is set to the right, and the output end of the second linear drive member 44 of the clamper 4 on the right is set to the left. When the output end of the second linear drive member 44 is extended, the upper support plate 421 and the lower support plate 422 protrude from the left and right side walls of the bracket 45, thereby realizing the abutment, limiting and supporting effects of the upper support plate 421 on the upper side of the sample and the lower support plate 422 on the lower side of the sample.

The two output shafts of the height adjustment motor 52 are respectively connected to all the height adjustment screws 53 through couplings and drive shafts to drive rotation. The clamp 4 is arranged on the opposite side of the two lifting platforms 51, so that the height of the lifting platform 51 can be accurately controlled by the height adjustment motor 52 in combination with the height adjustment screws 53, and the operation is stable, reliable and high-precision.

[0046] There can be one clamp 4 on each lifting platform 51, and it is preferably located in the middle of the lifting platform 51 in the front-to-back direction. In this case, it is possible to clamp shorter specimens. Alternatively, there can be at least two clamps 4 on each lifting platform 51, and they are spaced apart from each other from front to back, with the clamps 4 on the left and right corresponding to each other, so that a longer specimen can be stably clamped by multiple clamps 4.
