Description

Technical Field

[0001] This utility model belongs to the field of engineering testing technology, specifically relating to a device for assisting in the installation of a load cell. Background Technology

[0002] With the vigorous development of infrastructure construction in my country, cast-in-place piles are widely used in engineering fields such as highways, docks, and building construction. Cast-in-place piles are generally underground or underwater and belong to concealed works. In actual engineering applications, it is necessary to accurately determine their bearing capacity. The static load test of vertical compressive strength of a single pile can be carried out by the surcharge method, the anchor pile method, and the self-balancing method. Among them, the self-balancing method is simple to operate, not limited by the site, and has been used in many projects at home and abroad.

[0003] Chinese patent, publication number CN220521421U, discloses a safety load box that is easy to install. By setting a sliding block, the locking blocks at both ends of the pushing device are aligned with the mounting slots on the first connecting plate and the second connecting plate and inserted. The locking blocks contact the inclined surfaces on the two sliding blocks. As the locking blocks are inserted, they move along the inclined surfaces, pushing the sliding blocks into the empty slots. Then the locking blocks pass over the sliding blocks. When the locking blocks are fully inserted into the mounting slots, the sliding blocks and locking blocks are aligned. Under the push of the first spring, the sliding blocks are pushed into the locking slots, locking the locking blocks and locking the pushing device between the first connecting plate and the second connecting plate.

[0004] The load cell is the most important piece of equipment in the self-balancing method and needs to be installed in the steel cage in advance. The general procedure for installing the load cell is as follows: cut the steel cage at the installation position of the load cell, place the load cell at the cut position, and weld a ring of connecting bars and bell bars. In the installation of the load cell, it is difficult to adjust the load cell to the appropriate position, and the welding work is more complicated when the main bars of the steel cage are dense.

[0035] Working principle: All electrical components mentioned in this application are externally connected to a power supply and control switch during use. After installation, first check the installation, fixation, and safety precautions of this utility model before use. During use, place the prepared rebar cage 20 on top of the rotating rod 3, and cut the rebar cage 20 at the installation position of the load box 19. During this process, it is necessary to turn on the motor 2 to adjust the cutting surface of the rebar cage 20. Place the trumpet-shaped rebar support mechanism 6 inside the load box 19, and then place the load box 19 at the cutting position of the rebar cage 20. Adjust the position of the load box 19 using the load box translation mechanism 5. The load cell 19 is embedded into the long and short sections of the reinforcing cage 20 at a certain distance on the left and right sides respectively. The connecting bars 21 are welded to connect the load cell 19 and the reinforcing cage 20. During this process, the reinforcing cage 20 needs to be rotated to adjust the welding working surface. After the welding of the connecting bars 21 is completed, the height of the arc support 11 of the load cell translation mechanism 5 is lowered to the minimum. The position of the support 18 in the trumpet bar support mechanism 6 is adjusted, and the trumpet bar 22 is placed on it. The welding of the trumpet bar 22 is carried out. During this process, the reinforcing cage 20 also needs to be rotated. After the welding of the trumpet bar 22 is completed, the trumpet bar support mechanism 6 is removed, and the installation of the load cell 19 is completed.
