Description

Technical Field

[0001] This utility model belongs to the technical field of material storage devices, specifically relating to a staggered adjustable anti-roll-off pipe layer stacking device. Background Technology

[0002] In construction, municipal engineering, and pipe storage scenarios, long and narrow pipes such as steel pipes, fire-fighting pipes, and PPR pipes are used in large quantities. Their standardized stacking directly affects the safety management, space utilization, and material turnover efficiency of the construction site. According to construction requirements, pipes must be stacked in layers off the ground, prevent rolling, and be classified and stacked to avoid safety accidents caused by collapse or slippage, while ensuring convenient access to materials. In existing technologies, pipe stacking solutions can be mainly divided into three categories: The first category is the simple stacking method most common on construction sites, which uses wooden blocks or concrete blocks as bottom supports, and the pipes are directly stacked on the blocks and bound with wire for restraint. This method lacks a reliable lateral restraint structure, and round pipes are prone to rolling and collapse under external disturbances, posing a significant safety hazard; The second category is fixed integrated pipe racks, which use a welded structure of columns and multiple cantilever arms. However, the arm spacing is fixed, which can only accommodate a single or a few types of pipe diameters and cannot simultaneously meet the needs of heavy metal steel pipes and light plastic pipes. The first type is a stacking rack for pipe materials, which has extremely poor versatility and a large overall welded structure that is heavy and difficult to adapt to the frequent relocation of construction sites. When not in use, it takes up a lot of space. The second type is an adjustable pipe storage rack, which uses screw drive, telescopic rod extension and retraction to continuously adjust the distance between the arm to accommodate pipes of different diameters. However, its adjustment mechanism relies on precision moving parts. In the harsh environment of construction sites with high dust, mud and water, and frequent material collisions, the adjustment structure is prone to jamming, jamming or even failure due to dust accumulation, corrosion and deformation. This results in high maintenance costs and short service life.

[0003] Chinese patent CN219858515U discloses an adjustable pipe stacking device, comprising several unit components for supporting the pipes, the unit components being disposed at the bottom of the pipes; each unit component includes a first horizontal plate and a second horizontal plate arranged side by side; it also includes a transverse screw, the two ends of which pass through the first and second horizontal plates respectively, and are provided with a washer and nut at the end; two third horizontal plates are respectively fixed to the upper surfaces of the first and second horizontal plates; the third horizontal plates are provided with several first vertical pin holes, and a fourth horizontal plate is provided in conjunction, the fourth horizontal plate having second vertical pin holes that match the first vertical pin holes. The fourth horizontal plate of this patent can be adjusted in position on the third horizontal plate through the pin holes and the pins engaging, thereby conforming to the outer wall of pipes of different diameters, reducing pipe rolling while ensuring safety, reducing wear on the anti-corrosion layer of the pipe surface, and improving project quality. However, the main width adjustment of this patent relies entirely on the transverse reverse screw, which is prone to dust and rust accumulation in harsh environments with high dust and mud on construction sites, resulting in poor adjustment reliability and easy failure. Meanwhile, the patent uses a vertical fourth horizontal plate as a lateral limiting structure, and the side is a flat plate with a vertical upward shape. It has weak resistance to lateral pressure and is very easy to deform outward or even bend and break under the lateral thrust of the pipe, resulting in insufficient anti-roll-off stability. Utility Model Content

[0004] The purpose of this utility model is to provide a staggered adjustable anti-roll-off pipe layer stacking device, which can adapt to the harsh working conditions of construction site with high dust, mud and water and frequent material collisions. It is stable and reliable in operation and has high stacking safety.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An adjustable anti-roll-off pipe stacking device includes at least two stacking units spaced apart along the length of the pipes to be stacked. Each stacking unit has two opposing baffle base components. Each baffle base component includes a limiting baffle and a fixed base. The lower end of the limiting baffle is fixedly connected to the fixed base. The fixed bases of the two baffle base components overlap each other along the length direction. The fixed bases have a number of reserved high-strength bolt holes arranged sequentially along their own length direction. The two fixed bases are detachably fixedly connected by fixing limiting bolts passing through the mutually aligned reserved high-strength bolt holes. The inner sidewalls of the two limiting baffles and the upper surface of the fixed base together form an upward-opening receiving groove. The top of the limiting baffle is a flat horizontal bearing end face.

[0006] Furthermore, the limiting arm is an integrally bent rod, and the limiting arm includes a lower support section and an upper stop section from bottom to top; the lower end of the lower support section is fixedly connected to the upper surface of the fixed base, and the lower support section extends obliquely from bottom to top towards the outside of the fixed base.

[0007] Furthermore, the lower end of the upper retaining section is bent and connected to the upper end of the lower supporting section, and the upper retaining section extends obliquely from bottom to top towards the inner center of the fixed base.

[0008] Furthermore, the inner wall of the lower support section and the inner wall of the upper baffle section together form a limiting contact surface, and the limiting contact surfaces of the two oppositely arranged limiting arms and the upper surface of the fixed base together enclose a centrally enlarged bayonet-type accommodating space.

[0009] Furthermore, the axial length of the lower support section is less than the axial length of the upper stop section.

[0010] Furthermore, the angle between the lower support section and the upper surface of the fixed base is 65~80°.

[0011] Furthermore, the angle between the upper stop section and the lower support section is 100~120°.

[0012] Furthermore, several pre-drilled high-strength bolt holes are arranged at equal intervals along the length of the fixed base.

[0013] Furthermore, the overlapping and mating surfaces of the two fixed bases are flat planes.

[0014] Furthermore, the fixing base is made of channel steel or square steel profile, and the lower surface of the fixing base is provided with an anti-slip pad layer.

[0015] The beneficial effects of this utility model are as follows: This utility model employs a spacing adjustment method where the fixed bases of two arm-stopping components overlap and are locked in place by pre-drilled high-strength bolt holes. This method abandons the precision adjustment structures commonly used in existing technologies, such as screw drives and telescopic rods. The spacing of the two arm-stopping components can be adjusted simply by switching the aligned bolt holes and locking the fixing bolts. This adapts to harsh working conditions on construction sites, such as high dust levels, muddy conditions, and frequent material collisions, avoiding problems like adjustment jamming, thread corrosion, and structural deformation failure. The structure boasts strong impact resistance and low maintenance costs. The modular, overlapping structure allows for disassembly, storage, and flexible relocation, solving the shortcomings of fixed integrated racks, which are bulky and inconvenient for transport and storage. The arm-stopping components utilize a structure of limiting arms and fixed bases, resulting in high overall structural strength and load-bearing capacity. The inner walls of the two arm-stopping components and the upper surface of the fixed base together form an upward-opening receiving groove, providing continuous and stable lateral restraint for stacked circular pipes, preventing them from rolling off and ensuring the safety of material stacking on construction sites.

[0017] The present invention will now be described and illustrated in detail with reference to the embodiments.

[0018] Example 1 like Figure 1-4 As shown, the staggered adjustable anti-roll-off pipe layer stacking device includes at least two stacking units arranged at intervals along the length direction of the pipe 1 to be stacked. Each stacking unit is provided with two opposing baffle base components. The baffle base component includes a limiting baffle 2 and a fixed base 3. The lower end of the limiting baffle 2 is fixedly connected to the fixed base 3. The fixed bases 3 of the two baffle base components overlap each other along the length direction. The fixed base 3 has a number of reserved high-strength bolt holes 4 arranged sequentially along its own length direction. The two fixed bases 3 are detachably fixedly connected by fixing limiting bolts 5 passing through the mutually aligned reserved high-strength bolt holes 4. The inner sidewalls of the two limiting baffles 2 and the upper surface of the fixed base 3 together form an upward-opening receiving groove. The top end of the limiting baffle 2 is a flat horizontal bearing end face.

[0019] The limiting arm 2 is an integrally bent rod. The limiting arm 2 includes a lower support section 201 and an upper stop section 202 from bottom to top. The lower end of the lower support section 201 is fixedly connected to the upper surface of the fixed base 3. The lower support section 201 extends obliquely from bottom to top towards the outside of the fixed base 3.

[0020] The lower end of the upper baffle section 202 is bent and connected to the upper end of the lower support section 201. The upper baffle section 202 extends obliquely from bottom to top towards the inner center of the fixed base 3.

[0021] The inner wall of the lower support section 201 and the inner wall of the upper baffle section 202 together form a limiting contact surface. The limiting contact surfaces of the two oppositely arranged limiting arms 2 and the upper surface of the fixed base 3 together enclose a centrally enlarged bayonet-type accommodating space.

[0022] The axial length of the lower support section 201 is less than the axial length of the upper stop section 202.

[0023] The angle between the lower support section 201 and the upper surface of the fixed base 3 is 65~80°.

[0024] The angle between the upper stop section 202 and the lower support section 201 is 100~120°.

[0025] Several reserved high-strength bolt holes 4 are arranged at equal intervals along the length of the fixed base 3.

[0026] The overlapping surfaces of the two fixed bases 3 are flat planes.

[0027] The fixing base 3 is made of channel steel or square steel profile, and the lower surface of the fixing base 3 is provided with an anti-slip pad layer.

[0028] Working principle and process: Before use, adjust the overlap length of the fixed base 3 of the two relatively arranged retaining arm base components according to the pipe diameter and load-bearing requirements of the pipe 1 to be stacked, so that the corresponding reserved high-strength bolt holes 4 are aligned with each other; insert the fixed limiting bolts 5 into the aligned reserved high-strength bolt holes 4 and lock them in place to complete the adjustment of the distance between the two limiting retaining arms 2. When stacking heavy metal pipes such as steel pipes, use the reserved high-strength bolt holes 4 on the inner side to reduce the distance and strengthen the lateral limiting strength; when stacking light plastic pipes such as PPR, switch the reserved high-strength bolt holes 4 to the outer side to increase the distance and improve the single-slot capacity.

[0029] After the spacing is adjusted, at least two sets of stacking units are arranged at intervals along the length of the pipe 1 to be stacked, so that the opening of the receiving groove enclosed by the two limiting arms 2 faces upward; the pipe 1 is hoisted into the receiving groove layer by layer, the bottom of the pipe 1 is supported on the upper surface of the fixed base 3, and the pipe 1 is laterally constrained and limited by the inner sidewalls of the two limiting arms 2; the lower support section 201 supports the lower part of the stacked pipe 1, and the upper baffle section 202 restricts the upper part of the stacked pipe 1 from expanding outward. The bayonet-type receiving space formed by the two can restrict the lateral rolling of the stacked pipe 1, avoid rolling and collapse, and achieve stable single-layer stacking.

[0030] After the pipes 1 are stacked, the fixed base 3 of another stacking unit can be placed stably on the horizontal bearing end face of the top of the two sets of limit arm 2 of the lower layer. Relying on the natural alignment and fit of the horizontal bearing end face, the upper frame can be built without additional columns or connecting components, making full use of the vertical space of the site and improving the space utilization rate.

[0031] When materials are being transferred or the equipment is not in use, unscrew the fixing limit bolts 5 and separate the two overlapping fixing bases 3 to disassemble and store each arm base component. The disassembled components are small in size, making them easy to transport and move, and suitable for the frequent relocation needs of the construction site.
