Description

Technical Field

[0001] This utility model relates to the technical field of landscape paving construction equipment, and in particular to a device for preventing the tipping and moving of paving materials during landscape paving construction. Background Technology

[0002] In landscaping, building construction, and municipal engineering, mobile carts are frequently used to transport large slabs such as stone slabs, cement boards, and tiles to work sites. These slabs are typically heavy, have smooth surfaces, and poor stacking stability. Currently, preventing the slabs from slipping or tipping over during transportation, especially on uneven, muddy surfaces common at construction sites, is a crucial safety and technical issue. Existing anti-tipping methods involve welding metal fences or barriers to handcarts. However, these barriers have a fixed height and cannot accommodate stacks of varying heights. They provide ineffective protection for lower stacks and hinder loading and unloading for excessively high stacks. Furthermore, being rigid structures, they cannot provide continuous pressure based on the real-time condition of the slabs. During severe bumps, the slabs can easily collide with the barriers and bounce back, still posing a risk of instability. Some devices also use insertable blocks or adjustable levers. While these devices solve the size adaptability problem to some extent, their adjustment process is often manual and discrete. They cannot achieve dynamic and adaptive continuous pressing during transportation. They only provide static blocking at the initial position. When the plate moves up and down or back and forth due to bumps, it may still cause subsequent tipping. Utility Model Content

[0003] The purpose of this utility model is to provide a device for preventing the tipping and moving of paving materials during landscape paving construction, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] This utility model provides a device for preventing the tipping and moving of paving materials during landscape paving construction, comprising:

[0006] A mobile trolley has a load-bearing platform for stacking plates. The edge of the load-bearing platform is provided with several pawl locking grooves, and a pawl is provided on one groove surface.

[0007] A gantry press has a pressure plate placed on top of a stack of plates and a vertical baffle placed on one side of the stack of plates. The pressure plate and the vertical baffle are rigidly fixedly connected. The lower part of the vertical baffle is provided with a rack surface. The vertical baffle is vertically inserted into the pawl locking groove. The pawl abuts against the tooth groove of the rack surface, so that the pawl restricts the vertical baffle to move only downward. The vertical baffle is provided with a counterweight.

[0008] This technical solution converts the vibration energy from road bumps into a practical anti-tipping clamping force. On bumpy roads, the counterweight tends to move up and down due to inertia. A vertical baffle acts as a lever arm, converting this kinetic energy into a continuously increasing downward pressure and lateral restraint force on the stack of plates. Furthermore, due to the unidirectional locking characteristic of the pawl and rack, this clamping force is "only forward, never backward," achieving a more stable effect during transportation, even on bumpy roads, preventing the plates from tipping over or slipping under harsh road conditions. Workers only need to lower the gantry clamp once after loading; all subsequent clamping and locking actions can be automatically completed by the vibration or bumps of the moving trolley, eliminating the need to stop midway for re-tightening. This significantly reduces labor intensity and improves transportation efficiency.

[0009] As an extension of the above solution: guide grooves are provided on both sides of the pawl locking groove, and guide lugs are provided on both sides of the vertical baffle corresponding to the guide groove positions. This extension ensures that the vertical baffle moves in the vertical direction, preventing it from twisting or shifting during use. The guide structure bears lateral forces, protecting the pawl and rack surfaces from primarily bearing vertical forces, thus improving the lifespan of the mechanism.

[0010] As an extension of the above solution, several rollers or balls are provided between the inner groove surface of the pawl locking groove and the side surface of the vertical baffle. This improves sliding friction to rolling friction, reducing frictional resistance and lowering the resistance of the vertical baffle as it descends. This ensures that the downward pressure generated by the counterweight is fully utilized to press the plate, rather than being consumed in overcoming friction, thus guaranteeing the reliability of the core function.

[0011] As an extension of the above solution: the pawl is equipped with a torque element, which provides torque so that the end of the pawl always moves towards the rack surface. This ensures that the end of the pawl always tends to press against the rack surface, guaranteeing that it can smoothly slide into the next tooth slot when descending on the rack surface, and quickly return to its locked position when subjected to reverse force, preventing slippage or tooth skipping and improving reliability.

[0012] As an extension of the above solution: a through hole is provided through the pawl locking groove from the outside of the load-bearing platform toward the inside of the pawl locking groove. A pull rod is provided on the through hole, and the end of the pull rod is hinged to the middle or end of the pawl. In this extension, the diameter of the through hole is larger than the diameter of the pull rod, so that the rod has a certain radial movement space in the through hole, avoiding the pawl from locking due to the hinge of the pull rod when moving. At the same time, a pull ring is provided at the head of the pull rod, which allows the worker to directly grab the pull ring for operation. During unloading, the pawl is disengaged from the tooth groove by pulling the pull rod, achieving easy unlocking.

[0013] As an extension of the above solution: the load-bearing platform is provided with several horizontal sliding rails corresponding to the positions of the pawl locking grooves, sliding blocks slidably disposed on the horizontal sliding rails, and quick-locking bolts passing through the horizontal sliding rails and abutting against the sliding blocks. The pawl locking grooves are disposed in the sliding blocks. The spacing between the pawl locking grooves symmetrically arranged on both sides of the load-bearing platform can be adjusted by adjusting the sliding blocks. After adjustment, it can be fixed by quick-locking bolts, enabling the device to adapt to stacks of plates of different widths and enhancing the versatility of the device.

[0014] As an extension of the above solution: the pressure plate includes a fixed pressure plate and several movable pressure plates. One end of the movable pressure plate is rigidly fixedly connected to the vertical baffle, and the other end is nested inside the fixed pressure plate with a threaded hole in the nested part. The fixed pressure plate has a straight through groove corresponding to the nested part of the movable pressure plate. A torsion bolt is provided on the straight through groove. The torsion bolt is locked in the threaded hole, so that the torsion bolt locks the movable pressure plate on the fixed pressure plate.

[0015] In this extended solution, the nested part of the movable pressure plate and the fixed pressure plate is locked by a screw to prevent the fixed pressure plate and the movable pressure plate from sliding relative to each other. After adjusting the position of the bottom sliding block, the effective width of the pressure plate is adjusted accordingly, which can keep the vertical baffle vertical and ensure the effective transmission of the clamping force.

[0016] As an extension of the above solution: the counterweight and the vertical baffle are detachably connected. The detachable connection can be a bolted connection, allowing the user to adjust the counterweight according to the total weight of the transported materials and the degree of road roughness, such as adding or removing counterweights or changing their center of gravity height.

[0017] As an extension of the above solution: the counterweight is connected to the vertical baffle via a disassembly assembly. The vertical baffle is provided with screw holes and locking bolts for fixing the disassembly assembly at different heights. In this extended solution, several screw holes are provided on the vertical baffle along the vertical direction of the baffle, that is, screw holes are provided at different heights. The disassembly assembly is locked to the screw holes by locking bolts. One or more counterweights are fixed to the disassembly assembly. The user can adjust the counterweight according to the total weight of the transported materials and the degree of road bumps, such as adding or removing counterweights or changing their center of gravity height.

[0018] As an extension of the above solution: a removable anti-slip pad is provided on the bottom surface of the pressure plate and / or the bearing surface of the load-bearing platform. The anti-slip pad increases the static friction between the pressure plate and / or the bearing surface and the plate, fundamentally suppressing the slight slippage of the plate, and forming a dual guarantee of anti-slip and anti-tilting with the gantry press frame.

Detailed Implementation

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] Reference Figures 1 to 5 The following are several embodiments of a landscape paving construction anti-tipping and moving device of the present invention.

[0031] In some embodiments, such as Figures 1 to 2 As shown, this utility model provides a device for preventing the tipping and moving of paving materials during landscape paving construction, comprising:

[0032] The mobile trolley 100 has a load-bearing platform 110 for stacking plates. The edge of the load-bearing platform 110 is provided with several pawl locking grooves 200, and a pawl 210 is provided on one groove surface of the pawl locking groove 200.

[0033] The gantry press 300 has a pressure plate 310 placed on top of the stack of plates and a vertical baffle 320 placed on one side of the stack of plates. The pressure plate 310 and the vertical baffle 320 are rigidly fixedly connected. The lower part of the vertical baffle 320 is provided with a rack surface 321. The vertical baffle 320 is vertically inserted into the pawl locking groove 200. The pawl 210 abuts against the tooth groove of the rack surface 321, so that the pawl 210 restricts the vertical baffle 320 to move only downward. The vertical baffle 320 is provided with a counterweight 322.

[0034] In this embodiment, there are eight pawl locking slots, two of which are symmetrically arranged on both sides of the load-bearing platform along the length direction, and the remaining six are symmetrically arranged on both sides of the load-bearing platform along the width direction. The rigid fixed connection between the pressure plate and the vertical baffle can be achieved by welding or integral casting to form a robust "L"-shaped integral component. This ensures that the inertial torque generated by the counterweight and the locking force of the pawl are efficiently and without loss transferred to the pressure plate, and converted into a vertical clamping force on the plate stack.

[0035] In this embodiment, before loading, the gantry press frame is manually lifted upwards, causing the rack surface at the bottom of the vertical baffle to disengage from the pawl or be positioned above the pawl locking groove, or initially, the moving trolley and the gantry press frame are separate units. Then, the plates are stacked on the load-bearing platform. After stacking, the gantry press frame is released or placed on top of the plate stack, allowing it to be pressed against the top surface of the plate stack by its own weight. At this time, the vertical baffle is inserted into the pawl locking groove, and the pawl slides through the tooth groove on the rack surface, making a "click" sound. When the pressure plate is pressed against the top surface of the plate stack, the pawl is locked in the tooth groove of the current rack surface. The counterweight can be pre-attached to the vertical baffle or hung after the vertical baffle is inserted into the pawl locking groove, relying on the weight of the pressure plate and the counterweight itself to provide initial preload.

[0036] When the trolley bumps upwards on an uneven surface, the trolley body moves upwards momentarily. However, due to inertia, the heavy counterweight tends to maintain its original state of motion, creating a downward relative motion tendency relative to the upward-moving trolley body. This generates a downward torque relative to the upward-moving trolley body, resulting in a downward increase in the clamping force of the entire gantry press. When the trolley bumps downwards, the trolley body falls instantly. Similarly, the counterweight tends to move upwards due to inertia. At this time, the pawl and toothed groove come into play. The pawl locks into the toothed groove on the rack surface, preventing any upward rebound of the gantry press and maintaining the previously increased clamping force. This cycle repeats itself. With each bump, the relative movement between the vehicle body and the counterweight causes the pawl to slide across a tooth groove on the rack surface, allowing the pressure plate to drop a tiny height under its own weight. In other words, each bump can cause the gantry press to move downward by a tiny tooth pitch under inertial drive, continuously increasing the clamping force until a stable locking state is reached. This achieves the effect of increasing clamping force with each bump, realizing a purely mechanical, self-adaptive, unidirectional clamping anti-tipping function, preventing the plates from tipping over during transportation and improving safety.

[0037] Those skilled in the art can understand that to ensure reliable self-locking, the locking parameters of the pawl, such as the angle between the working surface of the pawl and the inclined plane of the tooth groove, and the tooth pitch of the tooth groove, are set according to actual usage requirements. The working principle of the one-way locking of the pawl is a mature mechanical structure and will not be elaborated here. Technicians can set the self-locking angle of the pawl (such as less than 6° - 8°), the tooth pitch of the rack surface (such as 5 - 8 mm), etc. according to the existing technology, as long as the vertical baffle can be prevented from moving only downward unidirectionally during transportation to maintain the pressing force. It should be noted that the weight of the counterweight is preferably 5 - 10 kg. When the mobile trolley jolts with an acceleration of about 5 m / s², the inertial force generated by the counterweight is sufficient to reliably overcome the frictional resistance of the mechanism when the vertical baffle moves downward, and drive it to move downward by one tooth pitch. The weight of the counterweight is only about 1% to 3% of the total weight of the transported plates, but it can convert the jolting kinetic energy into a significant dynamic pressing force without increasing the labor intensity of workers.

[0038] In this embodiment, the road surface jolting vibration energy is converted into a practical anti-overturning pressing force. On the bumpy road surface, the counterweight has a tendency to move up and down due to inertia. Through the vertical baffle as a lever arm, this kinetic energy is converted into an increasingly large downward pressure and lateral restraint force on the plate stack. And due to the one-way locking characteristic of the pawl and the rack surface, this pressing force is "only forward and not backward", achieving the effect of being more stable during transportation as the road surface is more bumpy, and preventing the plates from overturning and slipping under poor road conditions. Workers only need to lower the gantry pressing frame once after loading, and all subsequent pressing and locking actions can be automatically completed by the vibration or jolting during the movement of the trolley without having to stop midway to tighten again, significantly reducing the labor intensity and improving the transportation efficiency.

[0039] In an alternative embodiment, as Figure 1 and Figure 3 shown, on both sides inside the pawl locking groove 200, guiding grooves 220 are provided, and guiding lugs 323 corresponding to the positions of the guiding grooves 220 are provided on both sides of the vertical baffle 320. The shapes of the guiding grooves 220 and the guiding lugs 323 can be in the shape of, for example, a "convex" shape or a燕尾形 (swallowtail shape). The guiding settings of these two shapes are common linear guiding cross-sections, and the guiding extension directions of the guiding grooves 220 and the guiding lugs 323 are vertically up and down.

[0040] This embodiment ensures that the vertical baffle moves in the vertical direction, prevents it from twisting or shifting during use, the guiding structure bears the lateral force, and protects the pawl and the rack surface from mainly bearing the vertical force, improving the service life of the mechanism.

[0041] In an alternative embodiment, as Figure 2 and Figure 3As shown, a plurality of rollers 230 or balls are provided between the inner groove surface of the pawl locking groove 200 and the side surface of the vertical baffle 320. This embodiment improves sliding friction into rolling friction, reducing frictional resistance and lowering the resistance when the vertical baffle moves downward, so that the downward pressure generated by the counterweight can be fully used to press the plate, rather than being consumed in overcoming friction, thus ensuring the reliability of the core function.

[0042] In an optional embodiment, the pawl is provided with a torque element that provides torque so that the end of the pawl always moves toward the rack surface. The torque element is a torsion spring, sleeved on the pawl's pivot shaft, with one end fixed to the pawl locking groove and the other end fixed to the pawl, providing a constant torque to the pawl toward the rack surface. This embodiment ensures that the end of the pawl always tends to press against the rack surface, guaranteeing that it can smoothly slide into the next tooth slot when descending on the rack surface, and quickly return to its locked position when subjected to reverse force, preventing slippage or tooth skipping and improving reliability.

[0043] In an optional embodiment, such as Figure 2 As shown, a through hole is provided in the pawl locking groove 200 from the outside of the load-bearing platform 110 toward the inside of the pawl locking groove 200. A pull rod 240 is provided in the through hole, and the end of the pull rod 240 is hinged to the middle or end of the pawl 210. In this embodiment, the diameter of the through hole is larger than the diameter of the pull rod, so that the rod has a certain radial movement space in the through hole, avoiding the pawl from locking due to the hinge of the pull rod when it moves (if the pull rod is in contact with the inner wall of the through hole, it can only move linearly along the hole axis, while the pawl rotates around the axis). At the same time, a pull ring is provided at the head of the pull rod, which makes it convenient for workers to directly grab the pull ring for operation. In this embodiment, when unloading, the pawl is disengaged from the tooth groove by pulling the pull rod, realizing easy unlocking. In addition to being used by workers for gripping and operating, this pull ring is also used to limit the extreme position of the pull rod moving toward the pawl locking groove. When the vertical baffle is not inserted into the pawl locking groove, this pull ring can prevent the pawl from rotating excessively due to the torque of the torque component, ensuring that when the vertical baffle is inserted into the pawl locking groove, the end of the pawl always acts on the rack surface.

[0044] In some preferred embodiments, when the pull rod is pulled outward, the pull rod is always subjected to a force towards the pawl locking groove due to the torque provided by the torsion member of the pawl. At this time, the pull rod can be prevented from retracting after being pulled out by inserting a small limiting workpiece such as a locking plate or locking strip between the pull ring at the head of the pull rod and the side of the load-bearing platform. Alternatively, a corresponding limiting structure can be set on the pull rod, such as a laterally sliding locking block on the side of the load-bearing platform corresponding to the through hole. After the pull rod is pulled out, it slides laterally towards the through hole to lock the pull rod. However, this setting increases the complexity of the side structure of the load-bearing platform. This preferred embodiment can achieve this with a simple limiting workpiece, and it is also beneficial for the implementation of the pawl locking groove in another optional embodiment of this embodiment to be adjusted to adapt to different plate widths by a sliding block. Therefore, this utility model does not limit the means of fixing the pull rod after it is pulled out to prevent retraction; the technician can set it according to actual usage requirements.

[0045] In an optional embodiment, such as Figure 1 and Figure 3 As shown, Figure 3 The structure shown on the right is a schematic diagram of the sliding block in this embodiment. Figure 1 The cross-sectional view of the sliding block in this embodiment is shown at position B. The load-bearing platform 110 is provided with several horizontal sliding rails 111 and sliding blocks 112 that are slidably disposed on the horizontal sliding rails 111, and quick-locking bolts 113 that pass through the horizontal sliding rails 111 and abut against the sliding blocks 112. The pawl locking groove 200 is disposed in the sliding block 112.

[0046] In this embodiment, the distance between the pawl locking slots symmetrically arranged on both sides of the load-bearing platform can be adjusted by adjusting the sliding block. After adjustment, it can be fixed with quick-lock bolts, allowing the device to adapt to stacks of plates of different widths and enhancing its versatility. Those skilled in the art will understand that increasing the distance between the pawl locking slots will cause the vertical baffle of the original gantry press to tilt. In this case, a larger gantry press is needed to achieve the pressing of the plates. Alternatively, the adjustable width or length of the pressure plate in the optional embodiments of this invention can be used to achieve the purpose of this invention.

[0047] In an optional embodiment, such as Figure 1 and Figure 4 and Figure 5As shown, the pressure plate 310 includes a fixed pressure plate 311 and several movable pressure plates 312. One end of the movable pressure plate 312 is rigidly fixedly connected to the vertical baffle 320, and the other end is nested inside the fixed pressure plate 311, with a threaded hole 314 on the nested part 313. The fixed pressure plate 311 has a straight through groove 315 corresponding to the nested part 313 of the movable pressure plate 312. A torsion bolt 316 is provided on the straight through groove 315. The torsion bolt 316 is locked in the threaded hole 314, so that the torsion bolt 316 locks the movable pressure plate 312 on the fixed pressure plate 311.

[0048] In this embodiment, a straight through slot and a torsion bolt are common methods for achieving telescopic locking. The nested portion of the movable pressure plate and the fixed pressure plate is locked by the torsion bolt to prevent relative sliding between the fixed pressure plate and the movable pressure plate. In this embodiment, appropriately increasing the area of ​​the movable pressure plate nested in the fixed pressure plate can increase the stability and stress stability of the entire pressure plate formed by the fixed pressure plate and the movable pressure plate. As in this embodiment, taking the end of the movable pressure plate connected to the vertical baffle as the rear end direction, the nested portion includes the front end of the movable pressure plate and the left and right sides of the movable pressure plate, which are respectively embedded in the interior of the fixed pressure plate (e.g., Figure 4 In the dotted section shown, after the screw is locked, the force of the vertical baffle can be better transmitted to the fixed pressure plate. After adjusting the position of the bottom sliding block in the above optional embodiment, the effective width of the pressure plate is adjusted accordingly in this embodiment to maintain the verticality of the vertical baffle and ensure the effective transmission of the clamping force.

[0049] Similarly, in an optional embodiment of this utility model, the method of adjusting the distance between the pawl locking grooves by means of the sliding rail and the sliding block, or the method of adjusting the width of the pressure plate by means of the fixed pressure plate and the movable pressure plate, can be applied to the vertical baffle, so that the vertical baffle can extend and retract in the vertical direction, and the loading height of the stacked plates can be adjusted according to the usage requirements.

[0050] In an optional embodiment, such as Figure 1 As shown, the counterweight 322 and the vertical baffle 320 are detachably connected. This detachable connection can be achieved using bolts or the connection structure of the disassembly assembly described in the optional embodiments below, allowing for height adjustment. This embodiment allows the user to adjust the counterweight according to the total weight of the transported materials and the degree of road roughness, such as by adding or removing counterweight blocks, to optimize the inertial clamping effect and achieve the best performance.

[0051] In an optional embodiment, such as Figure 1 As shown, the counterweight 322 is connected to the vertical baffle 320 via a disassembly assembly (not shown in the figure). The vertical baffle 320 is provided with screw holes 324 and locking bolts for fixing the disassembly assembly at different heights.

[0052] In this embodiment, the disassembly assembly is a component for assembling one or more counterweights. This embodiment does not limit the form of the component; it can be a block-shaped component for placing the counterweights or a plate-shaped component for fixing the counterweights. Several screw holes are provided on the vertical baffle along the vertical direction of the baffle, that is, screw holes are provided at different heights. The disassembly assembly is locked to the screw holes by locking bolts. One or more counterweights are fixed on the disassembly assembly. The user can adjust the counterweight according to the total weight of the transported material and the degree of road bumps, such as adding or removing counterweights or changing their center of gravity height.

[0053] In an optional embodiment, a removable anti-slip pad is provided on the bottom surface of the pressure plate and / or the bearing surface of the load-bearing platform. This embodiment increases the static friction between the pressure plate and / or the bearing surface and the sheet material, fundamentally suppressing minor slippage of the sheet material, and forming a dual guarantee of anti-slip and anti-tilting with the gantry press frame.

[0054] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
