Description

Technical Field

[0001] This utility model relates to the technical field of engineering consumable storage equipment, specifically to a road brick stacking rack. Background Technology

[0002] Paving bricks, also known as paving stones or floor bricks, are a type of building material mainly used for paving the ground. They are commonly used in key municipal projects such as sidewalk paving, plaza hardening, and environmental beautification. They also have a good effect on reducing surface runoff, protecting soil, and preventing erosion.

[0003] Currently, paving bricks are mostly made of clay, cement, granite, etc. Their mechanical properties are not resistant to impact, and they have a high density and are heavy. Handling and storing them is labor-intensive and requires extra care. Especially during loading and unloading, the stacked bricks are easily rearranged, and the bricks may break due to collisions between them.

[0004] To address this, the applicant proposes a new technical solution: a paving brick stacking rack that not only has a folding function but can also be transported to the construction site along with the stacked paving bricks, facilitating on-site construction. Utility Model Content

[0005] Therefore, this utility model provides a paving brick stacking rack to solve the problems of disordered stacking and brick breakage during the loading and unloading of existing paving bricks.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model discloses a paving brick stacking rack, comprising:

[0008] The hinged connecting beam has a pair of base frames symmetrically arranged on both sides. Each base frame has a pair of guide members symmetrically arranged on both sides. Each guide member has several universal ball pulleys at its bottom.

[0009] The wheel axle assembly is rotatably disposed at the end of the guide member and contacts the ground when the pair of base frames are folded.

[0010] The stop is hinged at its bottom end to the guide member via the wheel axle component, and the stop is adapted to deflect relative to the base frame within a right angle range, and a stop is provided for each pair of base frames.

[0011] Furthermore, the middle part of the stop is hinged to one end of the connecting rod, and the other end of the connecting rod is adapted to be connected to the guide member.

[0012] Furthermore, the guide includes:

[0013] The track has several universal ball pulleys evenly arranged at the bottom and a guide groove at the top;

[0014] The limiting slider is hinged at the top to the other end of the connecting rod and slidably disposed in the guide groove at the bottom.

[0015] The track has a front hinge hole at its front end, which is hinged to the hinge connecting beam. The track also has a rear hinge hole at its rear end, where a wheel axle component is rotatably mounted.

[0016] Furthermore, the wheel axle component includes a connecting shaft, a roller, and a limiting plate, and the connecting shaft is adapted to be inserted into the rear hinge hole, and the connecting shaft is inserted into the stop.

[0017] A roller is coaxially provided at one end of the connecting shaft, and the roller extends outward along the length of the track;

[0018] The limiting plate is installed at the other end of the connecting shaft.

[0019] Furthermore, the retainer includes a frame, a slot, a fixed shaft, and a hinge support. The connecting shaft is inserted into the hinge support, and the hinge support is welded and fixed to the bottom of the frame. A slot is provided in the middle of the frame, and a fixed shaft is provided in the slot. A connecting rod is slidably sleeved on the fixed shaft.

[0020] Furthermore, the hinged connecting beam includes:

[0025] Furthermore, the baffle is made of carbon fiber, and the base frame is made of stainless steel.

[0026] This utility model has the following advantages:

[0027] This utility model discloses a paving brick stacking frame that uses guide members to weld and fix the base frame, and uses a hinged connecting beam to connect two sets of guide members. Ball bearing pulleys are installed at the bottom of the guide members to improve the flexibility of the stacking frame's movement. The base frame is used to load paving bricks, and the hinged connecting beam effectively absorbs vibration loads from the base frame, thereby improving the stability of the base frame when moving paving bricks. In use, the brick stacks can be transported and unloaded to the construction site along with the bricks. This not only allows for the folding and storage of empty stacking frames, but also provides the stacking frame with good loading capacity. Furthermore, due to the combination of flexibility and stability, the stacking frame effectively alleviates the problem of brick scattering and breakage during unloading compared to existing technologies, which is beneficial for construction site management.

[0035] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Please refer to this as well. Figures 1-6 This utility model discloses a paving brick stacking rack for transporting or storing bricks as a whole. During unloading, the stacking rack and paving bricks are unloaded from the truck together, which can effectively alleviate the problem of paving bricks scattering and breaking during unloading. Specifically, the technical solution disclosed in this utility model will be described below by way of specific embodiments.

[0037] In one specific embodiment of this utility model, the paving brick stacking rack includes a hinged connecting beam 1, wheel axle components 3, and a retaining frame 5. The paving brick stacking rack is folded or unfolded via the hinged connecting beam 1. A pair of base frames 6 are symmetrically arranged on both sides of the hinged connecting beam 1. The base frames 6 are made of stainless steel and have anti-slip textures etched on their surfaces to prevent slippage of the paving bricks during transportation. A pair of guide members 2 are symmetrically arranged on both sides of the base frames 6, and the guide members 2 are fixedly connected to the base frames 6 by welding. Additionally, several universal ball bearing pulleys 7 are provided at the bottom of the guide members 2 to facilitate the stacking rack and bricks being tilted out of the truck bed when unloading bricks from a truck. In this embodiment, a wheel axle component 3 is provided at the end of the guide member 2. The wheel axle component 3 can rotate freely, and its main function is to... Figure 2 When the paving brick stacking rack is folded, the wheel axle component 3 contacts the ground, making it easier to organize and transport the empty stacking rack. In addition, the base frame 6 is provided with a stop 5, and the stop 5 is hinged to the guide member 2 through the wheel axle component 3. Furthermore, the stop 5 is adapted to deflect relative to the base frame 6 within a right angle range, thereby facilitating the folding of the stacking rack.

[0038] In some embodiments, such as Figure 3 The hinged connecting beam 1 includes a beam body 11 and a connecting hole 13. A leaf spring 12 is riveted to the top of the beam body 11, as shown below. Figure 1 and Figure 3 In terms of specific structure, a pair of connecting holes 13 are provided on both sides of the beam 11. Guide members 2 are installed on the connecting holes 13, allowing the guide members 2 to deflect around the connecting holes 13, thereby driving the base frame 6 to rotate relative to the beam 11, achieving the effect of free folding of the paving brick stacking frame. The leaf spring 12 is adapted to abut against the base frame 6. When the two base frames 6 deflect inward due to the load weight, the leaf spring 12 undergoes elastic deformation under bending moment. Therefore, when the truck is unloading, the leaf spring 12 can absorb the impact load acting on the bricks, thereby minimizing the problem of paving bricks breaking due to mutual impact during unloading. Furthermore, when the stacking frame is on the ground, since load-bearing legs 14 are welded to the bottom of the beam 11, the weight of the base frame 6 and the paving bricks can be supported by the load-bearing legs 14, thereby reducing the gravity load acting on the universal ball pulley 7, thus preventing the universal ball pulley 7 from deforming and failing due to excessive load.

[0039] In this embodiment, as Figure 4The middle part of the stop 5 is hinged to one end of the connecting rod 4, and the other end of the connecting rod 4 is adapted to be connected to the guide member 2. Thus, the connecting rod 4 can limit and fix the stop 5.

[0040] Specifically, in this embodiment, such as Figure 5 The guide component 2 includes a track 21, a guide groove 23, and a limiting slider 25. The track 21 has a guide groove 23 at its top and a number of omnidirectional ball bearing pulleys 7 at its bottom. When the palletizing frame is unfolded, the omnidirectional ball bearing pulleys 7 contact the ground or the bottom of the vehicle for easy unloading. Bricks are stacked on the base of the palletizing frame, allowing the frame to move via the rolling friction of the omnidirectional ball bearing pulleys 7. On the other hand, the limiting slider 25 is slidably disposed within the guide groove 23, and its top is hinged to the other end of the connecting rod 4. This allows the limiting slider 25 to restrict the rotation angle of the connecting rod 4, facilitating the unfolding of the palletizing frame.

[0041] In this embodiment, as Figure 4 The retainer 5 includes a frame 51, a slot 52, a fixed shaft 53, and a hinge support 54. The slot 52 is located in the middle of the frame 51, and the fixed shaft 53 is located inside the slot 52. A connecting rod 4 is slidably sleeved on the fixed shaft 53. The frame 51 is made of carbon fiber, which helps to reduce the overall weight of the stacking rack. The connecting shaft 31 is inserted into the hinge support 54, and the hinge support 54 is welded and fixed to the bottom of the frame 51. This prevents the frame 51 from interfering with the base frame 6 or the guide member 2 when it deflects.

[0042] In one specific embodiment disclosed in this utility model, such as Figure 6 The track 21 has a front hinge hole 24 at its front end, which is hinged to the hinge connecting beam 1. The track 21 also has a rear hinge hole 22 at its rear end, within which a wheel axle component 3 is rotatably mounted. Specifically, the wheel axle component 3 includes a connecting shaft 31, a roller 32, and a limiting plate 33. The rear hinge hole 22 is suitable for inserting the connecting shaft 31, which is inserted into the retainer 5. In other words, the wheel axle component 3, as an independent component, simultaneously achieves axle hole mating with both the rear hinge hole 22 and the hinge support 54. Based on this structure, the connecting shaft 31 mainly serves to fix the hinge support, while the other end of the connecting shaft 31 is fitted with a limiting plate 33, which abuts against the track 21 to prevent the connecting shaft 31 from dislodging. A roller 32 is also coaxially mounted on one end of the connecting shaft 31, extending outwards along the length of the track 21. Therefore, if... Figure 2 As shown, when the palletizing rack is in the folded state, since the track 21 is perpendicular to the ground, the roller 32 can contact the ground, and the palletizing rack can be moved using the roller 32.
