Description

Technical Field

[0001] This utility model belongs to the field of coal gangue brick processing technology, and specifically relates to a coal gangue brick stacking clamp. Background Technology

[0002] Currently, the main processing flow of coal gangue sintered bricks is as follows: coal gangue is crushed and screened to less than 2mm, then water is added, stirred and aged for more than 3 days, then it is formed into brick blanks by double-stage vacuum extrusion, then dried using residual heat, and finally sintered into bricks in a tunnel kiln at 1050–1150℃.

[0003] To ensure efficient and safe storage and transportation while maintaining brick quality, sintered coal gangue bricks typically require stacking. This stacking operation is generally accomplished using a stacking robot equipped with stacking clamps. Existing coal gangue brick stacking clamps generally feature a crisscrossing aluminum mounting frame, with a centering clamping mechanism driven by a set of cylinders at the bottom of the frame, thus enabling the clamping of multiple horizontally arranged bricks.

[0004] However, due to the heavy dust in the coal gangue brick truck environment, the cylinders in the aforementioned stacking fixtures are exposed and easily worn by dust, which shortens their service life and affects the stability of the fixtures. In addition, the aforementioned stacking fixtures only use one set of centering clamping mechanisms, which can only clamp the face of multiple horizontally arranged bricks, while neglecting to clamp their ends. This makes it easy for the bricks to be uneven in the stacking process, which will affect the neatness of the stacking. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0020] Example 1 To address the technical problems in the background section, the following coal gangue brick stacking clamp is provided: Combination Figures 1-7 As shown, a coal gangue brick stacking clamp includes a rectangular mounting box 1 with an open top. The top of the mounting box 1 is detachably sealed by a matching box cover 2, and a mounting platform 21 for detachable connection with an external stacking robot is vertically fixed to the middle of the top surface of the box cover 2. Symmetrical face plates 3 are erected on the outer sides of the two long sides of the mounting box 1, and the length of the face plates 3 is greater than the length of the long side of the mounting box 1. Symmetrical end plates 4 are erected on the outer sides of the short sides of the mounting box 1, and the length of the end plates 4 is greater than the length of the short side of the mounting box 1. The faceplate 3 is driven to move laterally by two cylinders 5 correspondingly arranged inside the long side of the mounting box 1. The two cylinders 5 are symmetrically distributed laterally along the short axis of the mounting box 1, and the piston rod of the cylinder 5 passes through the long side of the corresponding mounting box 1 and is detachably vertically connected to the corresponding faceplate 3. The end clamp 4 is driven to move laterally by two cylinders 6 correspondingly arranged on the inner side of the short side of the mounting box 1. The two cylinders 6 are symmetrically distributed laterally along the long axis of the mounting box 1, and the piston rod of the cylinder 6 passes through the corresponding short side of the mounting box 1 and is detachably vertically connected to the corresponding end clamp 4.

[0021] In the above technical solution, the mounting box 1 of the palletizing fixture adopts a rectangular structure with an open top, and is detachably sealed by the box cover 2 to form a closed shell. Cylinder 5 and cylinder 6 are respectively located on the inner side of the long side and the inner side of the short side of the mounting box 1, and the piston rod gap passes through the side wall of the mounting box 1 and connects to the external clamping plate. This closed design houses the cylinders inside the mounting box 1, avoiding direct intrusion of dust in the palletizing environment, significantly reducing the wear of the cylinder seals, thereby extending the service life of the cylinders and improving the stability and reliability of the fixture operation.

[0022] This palletizing fixture features two independent clamping mechanisms. A face clamping plate 3, driven by cylinder 5, clamps the face of the brick row 9 along the long side of the mounting box 1, while an end clamping plate 4, driven by cylinder 6, clamps the ends of the brick row 9 along the short side of the mounting box 1. The face clamping plate 3 is longer than the long side of the mounting box 1, and the end clamping plate 4 is longer than the short side of the mounting box 1, ensuring that the clamping range covers the entire size of the brick row 9. Through the coordinated action of the face clamping plate 3 and the end clamping plate 4, the brick row 9 is clamped simultaneously in both the horizontal and vertical directions, preventing unevenness in the brick row during clamping and handling, and effectively improving the neatness and stability of the stacking.

[0023] Example 2 Combination Figures 1-7 As shown, based on the above embodiments, this embodiment further provides the following: In this embodiment, as Figure 4 As shown, cylinder 5 and cylinder 6 are arranged in layers inside the mounting box 1.

[0024] In the above technical solution, by arranging the cylinder 5 of the drive face clamping plate 3 and the cylinder 6 of the drive end clamping plate 4 in an upper and lower layer within the mounting box 1, the three-dimensional space of the mounting box 1 is rationally utilized. This layout avoids the possible motion interference and space competition that may occur between the two sets of cylinders and their pipelines when they are located on the same plane, making the structure more compact and reasonable.

[0025] like Figure 2 , Figure 4 and Figure 5 As shown, a partition 11 of the same length is fixedly connected to the bottom surface of the mounting box 1 along its long axis, and the top surface of the partition 11 is flush with the top surface of the mounting box 1; two cylinders 5 located on the same long side of the mounting box 1 are placed on the same side of the partition 11, and two cylinders 6 located on the same short side of the mounting box 1 are placed on both sides of the partition 11.

[0026] In the above technical solution, the partition 11 is vertically fixed along the long axis of the mounting box 1 and is the same length as the mounting box 1, with its top flush with the box cover 2. This enhances the overall bending and torsional strength of the mounting box 1, effectively preventing the mounting box 1 from deforming due to its own weight and the weight of the cylinder under long-term load, thus ensuring the structural stability of the fixture.

[0027] The top of the partition 11 provides effective central support for the cover 2, and together with the side walls of the mounting box 1, it bears the load, preventing the cover 2 from collapsing in the middle due to frequent use or the load of the mounting platform 21, thus extending the service life of the cover 2.

[0028] like Figure 2 As shown, the mounting box 1 has two inner cavities separated by a partition 11, each with a horizontally detachable and symmetrically connected support plate 12; the second cylinder 6 is detachably connected to the top end of the corresponding support plate 12; and the first cylinder 5 is detachably connected to the bottom surface of the mounting box 1.

[0029] like Figure 3 and Figure 5 As shown, the two inner cavity end faces of the mounting box 1 are respectively integrally and vertically symmetrically fixed with U-shaped suspension frames 13, and the top surfaces of the two ends of the suspension frames 13 are respectively vertically connected with limit rods 131; the end of the bearing plate 12 is gapped through the two limit rods 131 corresponding to the same side, and the limit rods 131 are fixedly connected to the bearing plate 12 by nuts screwed on them.

[0030] In the above technical solution, the support plate 12 provides a support position for cylinder 6. The detachable design of the support plate 12 allows the support plate 12 and cylinder 6 on it to be removed as a whole simply by loosening the nut when it is necessary to repair or replace cylinder 5. The operation space is large and extremely convenient, which greatly reduces the maintenance difficulty and time cost.

[0031] The U-shaped suspension frame 13 and the limiting rod 131 provide stable positioning and support for the bearing plate 12. The nut on the limiting rod 131 can tighten the bearing plate 12, ensuring that the cylinder 6 will not shift or shake during operation, thereby ensuring the accurate transmission of driving force and clamping precision of the end clamping plate 4.

[0032] like Figures 1-3 As shown, the cover 2 has a pair of through holes 22 symmetrically spaced on both sides of the mounting platform 21 in the middle; the two bearing plates 12 have square holes 121 symmetrically spaced in the middle; the four through holes 22 and the two square holes 121 are used to connect the external air supply pipe.

[0033] In the above technical solution, holes are specially provided on the cover 2 and the support plate 12 for connecting external air supply pipes, allowing the air lines to be introduced into the sealed mounting box 1 in a standardized and centralized manner. This design effectively avoids the pipes from becoming tangled inside the box, protecting them from wear and preventing them from interfering with the cylinder movement. This also fixes the inlet and outlet of the pipes, facilitating sealing measures at the pipe penetration holes 22, further enhancing the dustproof sealing effect of the mounting box 1 and improving the reliability of the entire pneumatic system. Preferably, the square hole in the middle of the support plate 12 is relatively large, so that the cylinder 5 on the bottom surface of the mounting box 1 can be easily repaired without disassembling the support plate 12.

[0034] like Figure 1 , Figure 2 as well as Figures 4-7 As shown, the clamping plate 3 includes a long strip plate 31, and the piston rod of the cylinder 5 is detachably vertically connected to the long strip plate 31; a plurality of short strip plates 32 are vertically fixedly attached at equal intervals along the long side of the lower part of the outer facade of the long strip plate 31, and the inner facade of the short strip plate 32 is arranged opposite to the front of the horizontally placed brick row 9 to be clamped, and the height of the inner facade of the short strip plate 32 is greater than or equal to the front height of the brick row 9.

[0035] In the above technical solution, the faceplate 3 adopts a structure in which multiple short strips 32 are fixed at equal intervals on the lower part of the outer facade of the long strip 31. This design means that the surface in contact with the front of the brick row 9 is not a complete plane, but a contact surface composed of multiple independent short strips 32. This not only increases the friction with the brick surface and prevents slippage, but also distributes the clamping force on multiple points, which helps to adapt to the slight unevenness of the surface of the brick row 9, achieves a more uniform and stable clamping, and avoids damage to the brick edges due to stress concentration.

[0036] like Figure 1 , Figure 2 as well as Figures 4-7 As shown, the end clamp 4 is an inverted T-shaped structure. The piston rod of the second cylinder 6 is detachably vertically connected to the longitudinal part of the end clamp 4. The bottom edge of the transverse part of the end clamp 4 is flush with the bottom edge of the short strip 32. The height of the transverse part of the end clamp 4 is adapted to the height of the end face of the brick row 9.

[0037] like Figure 1 , Figure 2 as well as Figures 4-6 As shown, the longitudinal portion of the end clamp 4 has multiple elongated weight-reducing holes 41 that are vertically and equally spaced through it.

[0038] In the above technical solution, the end clamp 4 adopts an inverted T-shaped structure, which allows the end clamp 4 to abut against the entire end face of the brick row 9 with its lateral part, providing sufficient support area, ensuring a firm clamping, and effectively preventing the brick row 9 from shifting or becoming uneven in the end direction. The weight-reducing holes 41 can effectively reduce the self-weight of the end clamp 4 without significantly affecting the structural strength and rigidity.

[0039] Example 3 Combination Figure 2 , Figure 4 and Figure 5 As shown, based on the above embodiments, this embodiment further provides the following: In this embodiment, guide components 7 are symmetrically inserted laterally through the two long sides of the mounting box 1, and the outer movable end of the guide component 7 is detachably vertically connected to the corresponding face plate 3; guide components 8 are symmetrically inserted laterally through the two ends of the mounting box 1, and the outer movable end of the guide component 8 is detachably vertically connected to the corresponding end plate 4; the guide component 7 and guide component 8 have the same structure. The guide assembly 7 includes a linear bearing 71 fixed to the inner side of the corresponding long side of the mounting box 1. A guide shaft 72 is axially slidably connected to the linear bearing 71. The outer end of the guide shaft 72 extends beyond the mounting box 1 and is detachably vertically connected to the corresponding face plate 3. A limit cap 73 is axially connected to its inner end.

[0040] In the above technical solution, the introduction of guide assembly 7 and guide assembly 8 provides better linear guidance, distributes harmful loads, and enhances system rigidity. The core component of guide assembly 7 and guide assembly 8 is the sliding fit between linear bearing 71 and guide shaft 72. This combination provides high-precision linear trajectory constraint for the lateral movement of face plate 3 and end plate 4. It effectively overcomes radial sway or torsion that may occur when driven solely by cylinders, ensuring that all plates move strictly in the predetermined direction during clamping and loosening. The limiting cap 73 prevents guide shaft 72 from accidentally disengaging from linear bearing 71.

[0041] Working principle and usage process of this utility model: In use, the entire fixture is mounted onto the external palletizing robot arm via the mounting platform 21 on the cover 2, and the external air supply pipeline is introduced into the sealed mounting box 1 through the through hole 22 of the cover 2 and the square hole 121 of the support plate 12, and connected to cylinder 5 and cylinder 6 respectively.

[0042] Initially, the piston rods of each cylinder are in the retracted state, and the drive face clamp 3 and end clamp 4 are in the open position away from the brick row 9. The clamping process begins after the palletizing robot moves the clamp above the brick row 9 to be clamped and lowers it into place. The external control system commands cylinders 5 and 6 to operate simultaneously. The piston rod of cylinder 5 extends, driving the two side clamping plates 3 to move towards each other, clamping the two main surfaces (front and back) of the brick row 9. Simultaneously, the piston rod of cylinder 6 extends, driving the two side end clamping plates 4 to move towards each other, clamping the two end faces of the brick row 9.

[0043] During the lateral movement of the clamping plates, the guide shafts 72 of guide assembly 1 7 and guide assembly 2 8 perform high-precision linear motion within the linear bearing 71, ensuring that the movement trajectory of the face clamping plate 3 and the end clamping plate 4 is straight and without wobbling.

[0044] The multiple short strips 32 at the bottom of the face clamp 3 increase the contact points and friction with the brick row 9, making the clamping more stable. The inverted T-shaped structure of the end clamp 4 fits against the end of the brick row 9 with its lateral part, together with the face clamp 3, to form a complete constraint on the brick row 9 from four directions, ensuring the neatness of the brick row 9.

[0045] The palletizing robot lifts the clamps and brick row 9, transporting them to the target stacking position. Upon reaching the designated position, the piston rods of cylinders 5 and 6 extend further simultaneously, causing all clamps to release brick row 9 and neatly place it on the stacking position. Subsequently, the clamps return to their initial state, ready to execute the next palletizing cycle.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
