Description

Technical Field

[0001] This utility model relates to the field of load cell technology, and more specifically, to an axially resistant lattice load cell. Background Technology

[0002] With the extensive use of pile foundations in engineering projects such as buildings, transportation, docks, and railways, it is necessary to optimize the axial bearing capacity of pile foundations in engineering design to ensure the safety of the project. At the same time, in order to accurately assess the axial bearing capacity of engineering piles, it is necessary to carry out on-site pile bearing capacity testing. Due to the widespread use of the self-balancing method for pile bearing capacity testing, one or more testing equipment load boxes need to be pre-embedded in the pile body and loaded step by step during construction.

[0003] Existing lattice-type load cells require welding and positioning with external reinforcing cages during use. When the reinforcing cage is cylindrical, it is prone to rolling during welding, requiring manual squeezing and positioning to complete the welding. This results in slow welding efficiency, and the inability to divert and discharge the pressure gas during pouring poses a risk of displacement. Furthermore, the installation stability is difficult to guarantee. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide an axially resistant lattice load cell to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an axially resistant lattice load cell, comprising an assembly positioning base plate, wherein a lattice load cell installation auxiliary device is detachably installed on the upper end of the assembly positioning base plate, the lattice load cell installation auxiliary device comprising: a welding positioning component, a cast-in-place reinforcement card compression-resistant component, a displacement wire assembly, and a pressure detector body, wherein the outer wall of the pressure detector body is installed on the inner wall of the welding positioning component and the cast-in-place reinforcement card compression-resistant component.

[0006] In a preferred embodiment, the welding positioning assembly includes: a side welding positioning plate, a welding mounting hole, and a welding mounting steel frame. The welding mounting steel frame is detachably installed inside the welding mounting hole, which is located at the upper end of the side welding positioning plate.

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.

[0020] As attached Figure 1-4 As shown, this utility model provides an axially resistant lattice load cell, including an assembly positioning base plate 1. A lattice load cell installation auxiliary device 2 is detachably installed on the upper end of the assembly positioning base plate 1. The lattice load cell installation auxiliary device 2 includes: a welding positioning component 21, a cast-in-place reinforcement card compression-resistant component 22, a displacement wire group 24, and a pressure detector body 23. The outer wall of the pressure detector body 23 is installed on the inner wall of the welding positioning component 21 and the cast-in-place reinforcement card compression-resistant component 22.

[0021] The welding positioning assembly 21 includes: a side welding positioning plate 212, a welding mounting hole 213, and a welding mounting steel frame 214. The welding mounting steel frame 214 is detachably installed inside the welding mounting hole 213. The welding mounting hole 213 is opened at the upper end of the side welding positioning plate 212. An outer base ring 211 is installed on the inner side of the side welding positioning plate 212. Multiple sets of side welding positioning plates 212 and welding mounting holes 213 are provided. One end of each set of side welding positioning plates 212 is installed on the outer wall of the outer base ring 211. Multiple sets of displacement wire groups 24 are provided. The lower ends of each set of displacement wire groups 24 are respectively installed on the upper end of each set of pressure detector bodies 23.

[0022] The casting reinforcement card pressure-resistant component 22 includes: an inner positioning ring 221, a casting and pouring groove 225, a gas flow replacement groove 224, a connecting positioning outer rod 223, and a flow divider assembly 222. One end of the flow divider assembly 222 is installed on the inner wall of the outer base ring 211. The gas flow replacement groove 224 is opened at the upper and lower ends inside the outer base ring 211. Multiple sets of displacement wire assemblies 24 are provided. Multiple sets of pressure detector bodies 23 are provided. Two sets of both the inner positioning ring 221 and the outer base ring 211 are provided. One end of each of the two sets of outer base rings 211 is installed at the upper and lower ends of the connecting positioning outer rod 223, respectively. The casting and pouring groove 225 is opened at the upper and lower ends inside the inner positioning ring 221. The outer wall of the inner positioning ring 221 is installed on the outer wall of the side of multiple sets of pressure detector bodies 23. The other outer wall of the pressure detector body 23 is installed on the inner wall of the outer base ring 211.

[0023] The specific implementation method is as follows: When using this utility model, the load box needs to be welded and positioned with the external reinforcing cage. When the reinforcing cage is cylindrical, it is prone to rolling during welding, requiring manual squeezing and positioning to complete the welding, which results in slow welding efficiency. When assembling the device, positioning can be achieved by connecting multiple sets of welded installation steel frames 214 through and into the welding installation holes 213 and the side welding positioning plates 212. After the side welding positioning plates 212 are positioned, the side welding positioning plates 212 and the welded installation steel frames 214 are welded together by hot-melt welding to achieve the positioning work. After both sets of welded installation steel frames 214 are installed, the positioning base plate 1 can be disassembled and assembled before the entire equipment is further assembled. During installation, when the entire equipment is being assembled and poured, the pouring and grouting tank 225 at the top can be used to assist in the pouring process. When the pouring and grouting tank 225 is being poured, the lower pressure gas can be circulated through the externally set gas flow displacement tank 224. The gas flow displacement tank 224 diverts and discharges the gas generated during the pouring of the entire equipment, which greatly reduces the problem of the entire device being unstable due to the large internal gas impact force caused by the large pouring pressure. This device achieves gas diversion by setting the pouring reinforcement card anti-pressure component 22, which greatly improves the stability of the entire device and further enhances the convenience and efficiency of the installation.

[0024] The working principle of this utility model is as follows: When using this utility model, the load box needs to be welded and positioned with the external reinforcing cage. Since the reinforcing cage is cylindrical, it is prone to rolling during welding, requiring manual squeezing and positioning to complete the welding, resulting in slow welding efficiency. During assembly, this device can be positioned by connecting multiple sets of welded installation steel frames 214 through and into the welding installation holes 213 and the side welding positioning plates 212. After the side welding positioning plates 212 are positioned, they are joined together by hot-melt welding. The 12 and the welded installation steel frame 214 are welded together to achieve positioning. After both sets of welded installation steel frames 214 are installed, the positioning base plate 1 can be disassembled and assembled before the entire equipment is installed. When the entire equipment is installed, assembled and poured, the pouring and grouting tank 225 at the upper end can be used to assist in the pouring work. When the pouring and grouting tank 225 is connected for pouring, the lower end pressure gas can be circulated through the externally set gas flow replacement tank 224. The gas flow replacement tank 224 diverts and discharges the gas generated during the pouring of the entire equipment.
