Description

Technical Field

[0001] This utility model relates to the field of road construction equipment technology, specifically a rapid concrete pavement brick laying device. Background Technology

[0002] With the continuous development of urban infrastructure construction, the number of ground paving projects such as sidewalks, squares, and parking lots is increasing. Concrete paving bricks are widely used due to their advantages such as high strength, good durability, and beautiful appearance. Traditional paving brick laying relies heavily on manual operation, which is labor-intensive and inefficient, making it difficult to meet the needs of modern high-efficiency construction. Therefore, various auxiliary paving equipment has gradually been introduced into construction sites to improve work efficiency and paving quality.

[0003] Existing concrete paving brick laying devices partially employ a suction cup structure for gripping and positioning paving bricks. They use vacuum adsorption to transfer bricks from their stacking location to the paving surface, enabling simultaneous handling of single or multiple bricks and improving work efficiency. However, this structure typically uses a rigidly connected suction cup array, lacking an effective flexible adjustment mechanism between the suction cup assembly and the main body of the device. When faced with uneven paving brick stacks, tilted surfaces of individual bricks, or slight undulations in the paving base, some suction cups cannot fully adhere to the brick surface, leading to a decrease in vacuum sealing. This easily results in problems such as weak adsorption, air leakage, or even brick detachment, affecting the continuity of paving and potentially causing brick damage, thus limiting its stable application in complex construction environments. Utility Model Content

[0004] The purpose of this utility model is to provide a rapid concrete paving brick laying device to solve the problems mentioned in the background art. The current concrete paving brick suction cup laying device has a rigid connection between the suction cup and the mounting plate, which makes it difficult for the suction cup to fully adhere to the brick surface when the paving bricks are stacked unevenly or the base surface is undulating. This can easily lead to problems such as poor adhesion, air leakage, and brick falling off.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid concrete paving brick laying device, comprising a lifting connecting frame, the bottom end of which is hinged to a rotatable suction cup frame, the suction cup frame having a plurality of suction cup units evenly arranged on it, each suction cup unit being connected to the suction cup frame via an elastic body connector, the elastic body connector being composed of a central elastic body and a plurality of auxiliary elastic support structures, the central elastic body being fixed on the non-adsorption side of the suction cup unit, the auxiliary elastic support structures being arranged around the central elastic body and connected to the suction cup frame to form a deformable elastic support system.

[0006] Preferably, the suction cup unit includes a vacuum suction cup body and an air extraction pipe connector. The top of the vacuum suction cup body is fixedly connected to the central elastic body, and the air extraction pipe connector extends from the side of the vacuum suction cup body.

[0007] Preferably, the bottom of the vacuum suction cup body is provided with an adjustable sealing ring, and the sealing ring is connected to the bottom of the vacuum suction cup body by a threaded connection.

[0008] Preferably, the central elastomer is a cylindrical rubber block, the bottom of which is fixedly connected to the bottom of the suction cup unit by bolts, and the top of the central elastomer is embedded in a groove on the suction cup frame.

[0009] Preferably, the auxiliary elastic support structure includes multiple spring plates and connecting rods. One end of each spring plate is fixed to the side wall of the central elastic body, and the other end is connected to the suction cup frame via the connecting rod.

[0010] Preferably, the suction cup holder is provided with multiple positioning holes, each of which corresponds to a connecting rod in the auxiliary elastic support structure, and the upper end of the connecting rod is inserted into the positioning hole and welded to fix it.

[0011] Compared with existing technologies, the beneficial effects of this utility model are: the rapid concrete paving brick laying device allows each suction cup to be independently adjustable in angle, effectively adapting to uneven brick surfaces, significantly improving the stability and reliability of adsorption, and increasing laying efficiency and construction safety. This device achieves multi-directional adaptive adjustment of the suction cups through a deformable elastic support system consisting of a central elastic body and multiple auxiliary elastic support structures between the suction cup unit and the suction cup frame. An adjustable sealing ring at the bottom of the suction cup unit further enhances sealing adaptability. The overall structure works synergistically to effectively solve the technical problem of poor adsorption of rigidly connected suction cups on uneven surfaces. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3This utility model provides a technical solution: a rapid concrete paving brick laying device, including a lifting connecting frame 1. The top of the lifting connecting frame 1 has an installation hole for connecting with a vehicle frame to achieve stable docking with the lifting mechanism of the whole machine. The bottom of the lifting connecting frame 1 is hinged to a rotatable suction cup frame 2, and a tilting drive cylinder is connected between the bottom of the lifting connecting frame 1 and the suction cup frame 2. One end of the tilting drive cylinder is hinged to the lower side wall of the lifting connecting frame 1, and the other end is hinged to the top middle of the suction cup frame 2. Several suction cup units 3 are evenly arranged on the suction cup frame 2. Each suction cup unit 3 is connected to the suction cup frame 2 through an elastic body connector 4. The elastic body connector 4 consists of a central elastic body 41 and multiple auxiliary elastic support structures 42. The central elastic body 41 is fixed to the non-adhesive side of the suction cup unit 3. An auxiliary elastic support structure 42 surrounds the central elastic body 41 and is connected to the suction cup frame 2, forming a deformable elastic support system. When the suction cup frame 2 adjusts its overall angle to adapt to the paving slope under the push of the tilting drive cylinder, and multiple suction cup units 3 contact unevenly stacked paving bricks, each suction cup unit 3 undergoes axial compression or torsional deformation through the central elastic body 41 connected to its non-adhesive side. Simultaneously, the multiple auxiliary elastic support structures 42 generate differential elastic deformation under uneven force, allowing each suction cup unit 3 to independently perform multi-angle deflection and micro-displacement adjustment around the central elastic body 41, ensuring that the bottom of all suction cup units 3 is fully in contact with the surface of each brick. The suction cup unit 3, with its adjustable sealing ring, achieves tight adhesion, effectively maintaining a vacuum seal and preventing air leakage caused by localized suspension. This significantly improves the stability and reliability of the suction cup frame 2 in simultaneously gripping multiple bricks under complex working conditions. It solves the problems in existing technologies where rigid connections of the suction cups lead to some suction cups failing to adhere to the brick surface, weak adhesion, easy detachment, and brick damage. The suction cup unit 3 includes a vacuum suction cup body 31 and an air extraction pipe connector 32. The top of the vacuum suction cup body 31 is fixedly connected to the central elastic body 41, and the air extraction pipe connector 32 extends from the side of the vacuum suction cup body 31. This structure ensures that when the suction cup unit 3 deflects due to uneven brick surfaces, the vacuum suction cup body 31, through its rigid connection with the central elastic body 41... The connection maintains the stability of force transmission, while the suction pipe connector 32 effectively avoids stress concentration and pipe twisting caused by traditional top-mounted pipes in an inclined state. This ensures that the air passage between the vacuum source and the internal cavity of the suction cup is always smooth and unobstructed, preventing connector detachment or seal failure due to changes in the suction cup's posture. This maintains a continuous and stable negative pressure suction force. Combined with the multi-directional adjustment capability of the elastic support system, the bottom of the vacuum suction cup body 31 is equipped with an adjustable sealing ring 33, which is connected to the bottom of the vacuum suction cup body 31 via a threaded connection. This structure allows for rotational adjustment of the sealing ring 33 to move up and down relative to the bottom of the vacuum suction cup body 31 along the threaded connection structure, thereby pre-adjusting the extension length of the sealing ring 33 according to the flatness of the paving brick surface.To ensure that the sealing ring 33 contacts the brick surface first and forms a tight seal at the moment of adsorption, it effectively compensates for the initial gap caused by local depressions or tilting, enhances the airtightness of the suction cup edge, prevents external air from entering through edge gaps and disrupting the vacuum negative pressure environment, and further reduces the risk of air leakage and brick falling off. The central elastic body 41 is a cylindrical rubber block, whose bottom is fixed to the bottom of the suction cup unit 3 by bolts, and the top of the central elastic body 41 is embedded in the groove on the suction cup frame 2. This structure forms a stable and flexible connection hub between the suction cup unit 3 and the suction cup frame 2. When subjected to adsorption reaction force, the central elastic body 41 can undergo axial compression and radial slight deformation, effectively buffering dynamic impact and allowing the suction cup unit 3 to move in the vertical direction. In this way, when multiple suction cup units 3 experience force differences due to uneven brick surfaces, each central elastic body 41 independently undergoes elastic deformation, working in conjunction with the auxiliary elastic support structure 42 to adapt to local height differences. This ensures that the suction cup frame 2 as a whole maintains a stable posture while each suction cup unit 3 can still tightly adhere to the brick surface. The system includes multiple spring plates 421 and connecting rods 422. One end of each spring plate 421 is fixed to the side wall of the central elastic body 41, and the other end is connected to the suction cup frame 2 via the connecting rod 422. When the suction cup unit 3 contacts an uneven brick surface, causing tilting or uneven local force, the multiple spring plates 421, through their own bending deformation capabilities, provide auxiliary elastic support in the radial and tangential directions. They deform synchronously with the deflection of the suction cup unit 3, and the other end transmits the deformation force to the suction cup frame 2 via the connecting rod 422, forming a multi-point cooperative force-bearing system. To ensure effective elastic recovery and prevent structural loosening and instability, the suction cup frame 2 is equipped with multiple positioning holes 21. Each positioning hole 21 corresponds one-to-one with a connecting rod 422 in the auxiliary elastic support structure 42. The upper end of the connecting rod 422 is inserted into the positioning hole 21 and welded in place. This structure provides a precise installation position reference for the connecting rods 422 in each auxiliary elastic support structure 42, ensuring that the connection angle and spatial layout of the connecting rods 422 and the spring plates 421 remain consistent, achieving symmetry and coordination in the multi-point elastic support system.

[0016] Working Principle: When using this concrete paving brick rapid laying device, firstly, it is connected to the lifting mechanism on the machine frame through the mounting hole at the top of the lifting connecting frame 1. The lifting mechanism drives the entire device to descend to a predetermined height above the brick stack. When the device approaches the concrete paving brick to be picked up, the vacuum system is activated, and the air extraction pipe connector 32 begins to extract air into the inner cavity of the vacuum suction cup body 31 to create negative pressure. Then, the operator adjusts the extension of the tilt drive cylinder according to the current paving surface slope, causing the suction cup frame 2 to rotate around the hinge axis and adjust to a suitable angle. As the device continues to descend, multiple suction cup units 3 contact the surface of the brick stack in sequence. At this moment, due to the difference in force at the moment of contact, the central elastic body 41 connected to each suction cup unit 3 undergoes compression deformation. When the spring plates 421 in the multiple auxiliary elastic support structures 42 bend and deform, each suction cup unit 3 completes independent posture adjustment in response to the elastic body connector 4. At the same time, by rotating the adjustable sealing ring 33 at the bottom of the vacuum suction cup body 31, its extension length is set. When all suction cup units 3 are in close contact with the corresponding brick surface, the vacuum negative pressure continues to act, completing the synchronous adsorption and gripping of multiple paving bricks. Subsequently, the lifting mechanism rises, lifts the brick as a whole and moves it above the paving position. It is then lowered again by the lifting mechanism, and the tilt drive cylinder is controlled to adjust the angle of the suction cup frame 2 to make it consistent with the base surface to be paved. After reaching the paving height, the vacuum system depressurizes, and the suction cup unit 3 releases the brick, thus completing a series of operations.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
