Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a building construction material lifting and transfer platform. Background Technology

[0002] ① The mainstream equipment for vertical material transfer in construction is the integral welded lifting platform. Its support frame height is fixed and cannot be adjusted. During non-operation periods, the entire machine occupies storage space and transfer relies on large hoisting equipment. At the same time, the base needs to be poured with concrete to prevent sinking on soft soil foundations and high-precision pre-embedded anchor bolts on hard rock foundations. This leads to the following problems: 1. High storage costs and low relocation efficiency during equipment downtime; 2. The complexity of the foundation pretreatment process is strongly related to geological conditions. The solidification period of soft soil is long, and excessive deviation of rock strata hole position leads to frame installation failure.

[0003] ② To address the above issues, the existing improvement plan adopts a split standard section tower frame, which is assembled into different heights by welding after being hoisted by a tower crane; the hopper is driven by an independent winch to rise and fall along the tower frame; to address the foundation issue, it adopts an integral steel foundation plate—the steel plate is laid on the soft soil foundation to diffuse the pressure, and the foundation plate is placed directly on the rock foundation after the surface is cleaned.

[0004] ③ A more prominent contradiction lies in the following: First, each assembly of the standard section requires on-site welding, and disassembly necessitates gas cutting to damage the structure, rendering it unusable (height adjustment is equivalent to reconstruction); second, the foundation slab relies solely on its own weight to contact the ground surface, which is insufficient to suppress soil rheological settlement caused by rainfall in soft soil foundations, and in hard rock foundations, it lacks downward anchoring force and cannot withstand horizontal loads under strong wind conditions. The essence of the defect is that height adjustment relies on destructive reconstruction, and the foundation treatment unit does not form a rigid mechanical anchorage with the geological layer. Utility Model Content

[0005] The purpose of this utility model is to provide a construction material lifting and transfer platform to solve the stability defects caused by the reliance on destructive restructuring for height adjustment and the failure of the foundation treatment unit to form a rigid mechanical engagement with the geological layer in the existing technology.

[0006] To achieve the above objectives, this utility model provides a construction material lifting and transfer platform, comprising multiple sets of vertically arranged extension rods, each set consisting of two extension rods, with a supporting crossbar fixedly installed between the two extension rods. A plug rod is fixedly installed at the bottom end of each extension rod, and a slot is provided at the top end of each extension rod. A plug rod or drive assembly of another extension rod is inserted into the slot and fixed with bolts. A pointed rod is bolted to the bottom end of each plug rod. The pointed rod is inserted into soft ground or inserted into a groove in a solid foundation to fix the extension rod.

[0007] The drive assembly includes an assembly rod that is inserted into a slot and is vertically fixed to one side of the bottom of the assembly frame.

[0008] The assembly frame has multiple fixing holes on the side away from the assembly rod, and the fixing holes are used for bolts to pass through and fix the assembly frame.

[0009] An assembly plate is fixedly installed on the side of the assembly frame away from the fixing hole. A bracket is installed on the assembly plate by bolts, and a lifting device is fixedly installed on the top of the bracket.

[0010] The output end of the lifting device is fixedly provided with a steel cable, the end of which passes through the bracket and pulley and is fixedly installed on the pull ring. The pulley is fixedly installed on one side of the assembly frame.

[0011] The pull ring is fixedly installed on one side of the lifting frame, a support rod is fixedly installed on the side of the lifting frame away from the pull ring, and a support block is fixedly installed on the side of the lifting frame away from both the support rod and the pull ring.

[0012] The support block is equipped with a roller with a shaft installed through a bearing. The roller with a shaft is attached to one side of the extension rod. The shaft of the roller with a shaft extends out of the roller and is provided with a limiting plate. The limiting plate is attached to the side of the extension rod opposite to the roller with a shaft.

[0013] This utility model discloses a construction material lifting and transfer platform. The supporting structure is based on multiple sets of vertically erected extension rods. Each set consists of two extension rods connected by a supporting crossbar to form a rigid gantry structure. The bottom of each extension rod has a detachable pointed end. This pointed end penetrates the soil layer directly in soft ground, creating a lateral compaction effect. In hard rock ground, it embeds into pre-drilled holes to create a mechanical locking mechanism, allowing the extension rod load to establish a rigid anchoring system between the extension rod and the ground. A slot at the top of the extension rod serves as the core expansion interface. By vertically inserting the bottom of a new extension rod into the existing extension rod slot and locking it with a horizontal bolt, along with the synchronous installation of the supporting crossbar, non-destructive height adjustment and overall stability control are achieved. This structure forms a modular, rapid assembly and disassembly system, replacing traditional destructive reassembly processes and significantly reducing storage space during non-operational periods. Simultaneously, the geologically adaptive anchoring mechanism of the pointed end effectively suppresses rheological settlement in soft soil foundations and eliminates the risk of overturning in hard rock foundations, constructing a complete force transmission closed loop from the extension rod to deep within the ground, ensuring dynamic structural stability under extreme conditions.

Detailed Implementation

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Please see Figures 1-4 .

[0022] This utility model provides a construction material lifting and transfer platform. The main body of the platform includes multiple sets of vertically arranged extension rods 101. Each set of extension rods 101 consists of two parallel components. The two extension rods 101 are fixedly connected by a support crossbar 102 to enhance the overall rigidity. A plug rod 103 is fixedly installed at the bottom end of each extension rod 101, and a slot 104 matching the size of the plug rod 103 is opened at the top end to realize the longitudinal connection between the upper and lower extension rods 101. When the extension rod 101 needs to be fixed to the ground, a detachable pointed rod 105 is added to the bottom end of the plug rod 103 by bolts. The pointed rod 105 can be directly inserted into the soft foundation or inserted after a groove is pre-cut on the surface of the solid foundation to form a stable support.

[0023] The drive assembly 106 serves as the lifting power source. Its assembly rod 107 is inserted into the slot 104 of the topmost extension rod 101 and locked with bolts. The assembly rod 107 is perpendicular to the bottom of the assembly frame 108 and fixed to one side there. On the other side of the assembly frame 108 opposite to the assembly rod 107, multiple fixing holes 109 are provided for bolts to pass through for auxiliary fixing or connection. An assembly plate 110 is fixedly mounted on the third side of the assembly frame 108, and a bracket 111 is mounted on the assembly plate 110 with bolts. A lifter 112 is fixed to the top of the bracket 111, and its output end is connected to a steel cable 113.

[0024] The path of the steel cable 113 is precisely designed: one end connects to the output end of the lifting device 112, passes sequentially through the mounting point at the top of the bracket 111, then descends around the pulley 114 fixed to one side of the assembly frame 108, and finally the end is fixed to the pull ring 115; the pull ring 115 is rigidly installed on one side wall of the lifting frame 116, and a support rod 117 is fixedly installed on the adjacent side wall of the lifting frame 116 corresponding to the pull ring 115; in addition, a support block 118 is installed on each of the other two sides of the lifting frame 116 (perpendicular to the support rod 117 and the pull ring 115); each support block 118 contains... Each extension rod 101 is equipped with a roller 119 via bearings. The roller 119's surface is in contact with the outer surface of the extension rod 101, serving as a guide. Shafts extend from both sides of the roller 119, and each shaft end is fixedly fitted with a limiting plate 120. The limiting plates 120 are arranged parallel to the extension rod 101 and are respectively in close contact with two opposite sides of the extension rod 101 corresponding to the roller 119's surface. This constitutes a three-way limiting structure to prevent the lifting frame 116 from derailing, ensuring the stability of the lifting frame 116's vertical movement along the extension rod 101.

[0025] Working principle: The insertion rod 103 at the bottom of the extension rod 101 is connected to the pointed rod 105. It is pressed directly into the soft foundation or inserted into the hard foundation after pre-grooving, so that the pointed rod 105 is anchored in the foundation to form a vertical support foundation. When multiple sets of extension rods 101 are fixed, the two extension rods 101 are rigidly connected by the support crossbar 102 to form a stable gantry structure. When it is necessary to increase the height of the platform, the insertion rod 103 at the bottom of the new extension rod 101 is inserted into the slot 104 at the top of the existing extension rod 101, and the modular stacking is achieved by locking with bolts, so that the structure can be flexibly expanded with the construction height.

[0026] The driving function is achieved through the top component: the assembly rod 107 of the drive component 106 is inserted into the slot 104 of the uppermost extension rod 101 and bolted in place. At this time, the assembly frame 108 is fixed to the material receiving platform (e.g., the upper floor) by bolts through the fixing holes 109. The assembly plate 110 on the side of the assembly frame 108 is equipped with a bracket 111 and a lifter 112. The steel cable 113 output by the lifter 112 extends downward, passing through the guide node at the top of the bracket 111 and the pulley 114 fixed to the assembly frame 108 in sequence, and finally connecting to the pull ring 115 of the lifting frame 116. When the lifter 112 is started to wind up the steel cable 113, the steel cable 113 is deflected by the pulley 114 to form a vertical lifting force, which pulls the lifting frame 116 up along the extension rod 101. When the steel cable 113 is released, the lifting frame 116 descends smoothly under the action of the material's gravity. The pulley 114 group effectively converts the direction of the force and reduces frictional energy consumption.

[0027] The stability of the lifting frame 116 during operation is ensured by a bidirectional limiting mechanism: rollers 119 with shafts are installed in the support blocks 118 on both sides of the lifting frame 116. The rollers 119 roll against the front of the extension rod 101 to bear the load. At the same time, the shaft passing through the rollers 119 extends outward and is fixed to the limiting plate 120. The limiting plate 120 is close to the back of the extension rod 101, so that the extension rod 101 is clamped between the rollers and the limiting plate 120. This double constraint completely suppresses the risk of lateral displacement or torsion of the lifting frame 116, ensuring that the material does not shake during the lifting process. The entire system is compatible with the design of the insertion rod 103 and the drive component 106 through the slot 104, realizing the quick interchange of the basic support and the power module. The coordinated clamping of the rollers 119 and the limiting plate 120 solves the problem of swaying during high-altitude lifting, forming an efficient, stable and scalable vertical transportation system.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
