Description

Technical Field

[0001] This utility model relates to the field of aerated concrete production technology, and in particular to a lifting mechanism for packaging aerated concrete blocks. Background Technology

[0002] In the context of aerated concrete block packaging and lifting technology, a key issue exists: contact friction between the lifted blocks and the unlifted blocks at the rear, leading to end-face damage. In traditional lifting mechanism designs, when the lifting seat vertically raises the blocks, due to conveying rhythm or positioning deviations, the lifted blocks are prone to lateral sliding contact with adjacent unlifted blocks, causing the following defects:

[0003] Friction damage: Scratches or debris are generated on the surface of the blocks under high pressure, which directly affects the appearance quality and masonry performance of the finished product.

[0004] Positioning misalignment: Frictional resistance causes the block stacks to tilt, increasing the risk of misalignment during the packaging process;

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a lifting mechanism for packaging aerated concrete blocks, making it more valuable for industrial use. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a lifting mechanism for packaging aerated concrete blocks.

[0007] This utility model discloses a lifting mechanism for packaging aerated concrete blocks, including a base fixedly installed on the foundation, four sets of support blocks on the upper surface of the base, one end of the support block being an upwardly inclined slope, a roller seat at the bottom of the lifting seat, a roller being movably installed in the roller seat via a shaft, the support block contacting the roller, a cylinder seat fixed on the base, a lifting cylinder being movably connected to the cylinder seat via a shaft, and the telescopic rod of the lifting cylinder being movably installed with a connecting seat at the bottom of the lifting seat via a shaft.

[0008] This aerated concrete block packaging lifting mechanism includes a base fixed to the foundation. The upper surface of the base is provided with four sets of support blocks. One end of each support block is an upwardly inclined ramp structure, and the other end is a horizontal support section or an extension block to accommodate the movement of rollers. A roller seat is fixedly installed at the bottom of the lifting seat. Rollers are movably installed in the roller seat through a rotating shaft. The rollers contact the ramp of the support block and roll along the ramp during the lifting process. A hydraulic cylinder seat is also fixedly installed on the base. The hydraulic cylinder seat is movably connected to the cylinder body of the lifting hydraulic cylinder through a rotating shaft. The end of the extension rod of the lifting hydraulic cylinder is movably connected to the connecting seat at the bottom of the lifting seat through a rotating shaft, thereby driving the lifting seat to rise and fall along the ramp trajectory of the support block through the extension and retraction of the hydraulic cylinder.

[0009] Furthermore, one end of the base has a vertically mounted end plate, and a top rod is fixed to the upper edge of the end plate. The top rod can contact the end face of the roller seat at the bottom of the lifting seat.

[0010] An end plate is vertically fixed to one end of the base. A top rod is rigidly connected to the upper edge of the end plate. The horizontal extension of the top rod forms an adjustable contact limit with the end face of the roller seat at the bottom of the lifting seat. The maximum displacement stroke of the roller seat when rolling along the slope of the support block can be controlled by setting the axial length of the top rod, thereby constraining the lifting height of the lifting seat, ensuring the stability of the mechanism during the lifting process and avoiding the risk of overtravel. At the same time, the combination structure of the end plate and the top rod provides the end mechanical stop function for the roller seat.

[0011] Furthermore, the end plate has a through hole, and the push rod has a threaded section. Two locking nuts are screwed into the threaded section, and the two locking nuts are located on both sides of the end plate.

[0012] A through hole is opened in the middle of the end plate. After the threaded section of the top rod passes through the through hole, two locking nuts are screwed into both ends of the threaded section to achieve bidirectional locking and positioning. The two locking nuts are located on the outer and inner sides of the end plate, respectively. By tightening the two nuts simultaneously, the axial extension length of the top rod can be precisely adjusted, thereby controlling the maximum travel limit of the roller seat on the slope of the support block. At the same time, the double nut interlocking mechanism enhances the vibration resistance and loosening ability of the top rod, ensuring the limit accuracy and structural rigidity during the lifting process. When the roller seat moves to the end face of the top rod, a physical stop is triggered, effectively avoiding equipment interference or block collision damage caused by the block lifting overtravel.

[0013] Furthermore, the front end of the ramp of the support block is a horizontal support section, and the end of the support block is an upward-extending stop.

[0014] The support block adopts a three-section composite structure design. The starting end of the ramp has a horizontal support section to provide a stable support surface for the roller in its initial static state. The end of the ramp extends upward to form a vertical stop. The contact between the stop and the end of the roller's rolling trajectory forms a mechanical limit, effectively preventing the roller seat from slipping due to inertia at the end of the lifting stroke. The horizontal support section, ramp section and vertical stop of the support block are integrally formed, which not only ensures the continuity of force transmission when the roller rolls along the ramp, but also limits the maximum backward position of the roller through the physical interference of the end stop.

[0015] Furthermore, the inner side of the roller has a raised retaining ring, which is locked inside the support block.

[0016] An integrated raised annular retaining ring is provided on the inner side of the roller. The inner diameter of the retaining ring matches the geometric contour of the side of the support block guide rail. Through the interlocking constraint between the retaining ring and the inner edge of the support block, the roller is ensured to maintain axial positioning when rolling along the slope of the support block, preventing the roller from radially shifting or detaching from the guide rail under lateral load.

[0017] Furthermore, the upper surface of the lifting platform is equipped with multiple slide rails, each slide rail is equipped with a slide cylinder, and a support plate is fixed on the slide cylinder. The support plate is used to place concrete blocks.

[0018] The upper surface of the lifting platform is arranged with two rows of linear array slide rails. Each slide rail is equipped with a high-precision slide cylinder. The piston rod flange end of the slide cylinder is fixed to the L-shaped support plate by bolts, forming a matrix block bearing platform. The horizontal working surface of the support plate is horizontal with the movement axis of the slide cylinder. Through the linear guidance constraint of the slide rail and the synchronous drive of the slide cylinder, the horizontal position of multiple concrete blocks can be finely adjusted.

[0019] Furthermore, multiple limiting posts are fixed on the outer side of the upper edge of the lifting seat, and a limiting block coaxial with the limiting posts is fixed at the bottom of the support plate, with the lower edge of the limiting block lower than the upper edge of the limiting posts.

[0020] Multiple limiting posts are fixed on the outside of the lifting seat, and corresponding limiting blocks are installed on the bottom of the support plate. The structural design of the lower edge of the limiting block being lower than the upper edge of the limiting post forms a mechanical limit to prevent abnormal displacement of the support plate.

[0021] By means of the above-described solution, the present invention has at least the following advantages:

[0022] 1. The inclined support block and roller design ensures a safe distance between the blocks and the unlifted parts during lifting, completely eliminating the surface scratches caused by traditional lifting methods.

[0023] 2. The adjustable top rod is locked by threads and double nuts, which is used to adjust the position of the top rod and limit the maximum travel distance of the lifting seat.

[0024] 3. The slide rail cylinder drives the support plate to move horizontally, and with the help of limit posts and limit blocks for double positioning, the neatness of the blocks during packaging is ensured.

[0025] 4. The inner retaining ring of the roller and the end stop of the support block form a two-way physical limit to prevent the equipment from deviating during the lifting process.

[0033] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0034] See Figure 1 The lifting mechanism is fixed to the foundation by the base 1. Four sets of inclined support blocks 2 guide the rollers 4 at the bottom of the lifting seat 3 to roll along the incline. The lifting cylinder 6 drives the lifting seat to vertically lift the blocks. After the cylinder is activated, the rollers 4 roll along the incline of the support block 2 until the end stop 11 limits the block, and the block is lifted to the set height. The slide cylinder 14 on the slide rail 13 pushes the support plate 15 to move laterally, and the blocks are stacked by nesting the limit post 16 and the limit block 17. The top rod 10 and the retaining ring 12 are adjusted to ensure lifting accuracy and prevent deviation. The cylinder resets to complete the cycle. The entire process is frictionless lifting and is suitable for efficient packaging of blocks of various specifications.

[0035] See Figure 1 The top rod 10 on the upper edge of the end plate 8 serves as a lifting stroke limit device. The lifting cylinder 6 pushes the roller 4 in the bottom roller seat 9 of the lifting seat 3 to roll up along the slope of the support block 2, thereby driving the block to rise vertically. When the end face of the roller seat 9 contacts the top rod 10, the lifting height is limited.

[0036] See Figure 1 and Figure 3The push rod 10 is vertically installed through the through hole of the end plate 8, and locking nuts 18 are screwed into both sides of its threaded section to adjust and fix the extension length of the push rod. During adjustment, the locking nuts on both sides are loosened, the push rod is adjusted to the preset height and then locked to ensure that the roller seat 9 at the bottom of the lifting seat 3 forms a mechanical hard limit when it rises to the contact of the end face of the push rod. The lifting cylinder 6 drives the roller 4 to roll and lift along the slope of the support block 2. The push rod 10 precisely limits the lifting height, and the locking nuts 18 prevent vibration and deviation.

[0037] See Figure 2 The horizontal support section at the front end of the support block 2 provides initial stable support for the roller 4, while the upward-sloping stop 11 at the end acts as a limit stop for the rolling stroke. The lifting cylinder 6 drives the roller 4 inside the roller seat 9 at the bottom of the lifting seat 3 to move upward at a constant speed along the slope of the support block 2. The horizontal section ensures a smooth start. When the roller contacts the stop 11, the lifting height is initially locked, and at the same time, the push rod 10 makes a secondary hard contact with the end face of the roller seat 9, forming a double limit. During reset, the cylinder retracts, and the roller slides down the slope in the opposite direction to return to its position in the horizontal support section. The stop 11 and the push rod 10 work together to control the stroke and avoid overshoot.

[0038] The roller 4 forms a lateral limiting structure with the inner side of the support block 2 through the inner protruding retaining ring 12 to prevent rolling deviation. The lifting cylinder 6 drives the roller 4 in the roller seat 9 at the bottom of the lifting seat 3 to move upward at a constant speed along the slope of the support block 2. The retaining ring 12 is always stuck in the inner guide groove of the support block 2 to ensure the axial stability of the roller.

[0039] See Figure 1 and Figure 4 Multiple sets of slide rails 13 are evenly distributed on the upper surface of the lifting seat 3. Each slide rail is equipped with a slide cylinder 14, and a support plate 15 is fixed to the top of its piston rod to support the concrete blocks. After the lifting cylinder 6 drives the lifting seat 3 to a preset height, the slide cylinder 14 extends laterally along the slide rail 13, driving the support plate 15 to unfold to the block stacking position. After stacking is completed, the slide cylinder retracts, the support plate returns to the center area of ​​the lifting seat, and the lifting cylinder descends to its original position. The slide rails 13 ensure rigid guidance for lateral movement, and the spacing of the support plates 15 is adjustable to adapt to different block sizes. Combined with the lifting-translation composite action, precise stacking and rapid reset are achieved, meeting the high-efficiency operation requirements of automated production lines.

[0040] Multiple limit posts 16 are fixed on the outside of the lifting seat 3. Limit blocks 17 are installed coaxially on the bottom of the support plate 15, with their lower edges lower than the upper edges of the limit posts 16, forming a translation overtravel protection. During operation, the slide cylinder 14 drives the support plate 15 to translate. When the translation distance exceeds the limit, the lower edge of the limit block 17 is forcibly contacted with the upper edge of the limit post 16, triggering a mechanical hard limit.

[0041] The working principle of this utility model is as follows:

[0042] The overall length of the formed block is 6000mm, while the standard block length is 1800mm. Therefore, a 1200mm section of the block at the front end needs to be separated and packaged separately. The 1200mm section at the front end is transported to the top of this device via a transport mechanism. This device is located between two parallel conveyor chains. When a lifting operation is required, the lifting cylinder 6 is activated, which drives the lifting seat 3 to move horizontally on the support block 2. The roller 4 at the lower end of the lifting seat 3 moves to the horizontal section at the front end of the support block 2, so that the block placed on the support plate 15 moves horizontally first and then moves obliquely upward, avoiding friction between adjacent blocks and causing block wear.

[0043] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
