Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an underground continuous wall joint brush device which is attached to a grab bucket of a troughing machine. Background Art

[0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place of construction is called "building construction site" or "construction site", also called construction site; underground continuous wall is a foundation engineering project that uses a trenching machine on the ground to excavate a long and narrow deep trench along the peripheral axis of the deep excavation project under the condition of mud wall protection. After cleaning the trench, a steel cage is hung in the trench, and then underwater concrete is poured into a unit trench section using the conduit method. This is carried out section by section to build a continuous reinforced concrete wall underground as a water-cutting, anti-seepage, load-bearing and water-retaining structure.

[0003] The utility model patent with authorization announcement number CN215053378U discloses an underground continuous wall joint brusher attached to a trenching machine grab, involving a trenching machine grab mounting frame, a positioning rod assembly and a brusher. The trenching machine grab mounting frame is fixedly mounted with a trenching machine grab, and the outer wall of the trenching machine grab is symmetrically provided with brusher connecting blocks. Compared with the traditional crane-controlled brusher with its own weight impact, the utility model designs an underground continuous wall joint brusher, which has a more reasonable force effect, is easy to control the verticality, has a good brushing effect and high efficiency. After the trenching machine is finished, the new brusher can be installed to achieve wall brushing without replacing equipment and occupies a small construction site. The scraper on the brusher is used to scrape off large pieces of mud or concrete blocks on the underground continuous wall joint, and then cleaned with a wire brush, which can greatly improve the efficiency and quality of wall brushing. The brushing time is shortened, the overall work efficiency is high, and the comprehensive cost is low.

[0004] Regarding the above solution: the connection between the wall brush and the grooving machine grab in the reference document is through a threaded connection of a positioning rod and a positioning nut. This connection method is prone to separation between the positioning rod and the positioning nut due to vibration generated by the wall brush and the grooving machine grab during operation, causing the wall brush to fall during operation, thereby causing damage to the wall brush, thereby reducing the service life of the wall brush, increasing the economic burden of the user, and easily causing hidden dangers to the personal safety of construction workers, affecting work efficiency.

[0032] The clamping mechanism 11 is used to clamp and fix the wall scrubber frame 3 and the supporting mechanism 5, and the buffer mechanism 7 cooperates with the supporting mechanism 5 to improve the stability of the wall scrubber frame 3 and reduce vibration.

[0033] Working principle: When the present invention is used, the wall brush frame 3 is moved to the front side of the square plate 51, and then the wall brush frame 3 is moved downward. The wall brush frame 3 drives the support plate 55 to move to the inner cavity of the bridge block 54, which can give the wall brush frame 3 a certain supporting force. Then, the dual-axis motor 111 is started, and the output shaft of the dual-axis motor 111 drives the threaded rod 112 to rotate, and the threaded rod 112 drives the threaded block 113 to move, and the threaded block 113 drives the limit block 123 to slide on the surface of the long rod 122. When the limit block 123 slides, it will drive the spring 2 124 to be compressed. When the threaded block 113 moves, it will drive one side of the block 114 to move out of the inner cavity of the shell 8, so that one side of the block 114 enters the inner cavity of the slot 53, and the wall brush frame 3 can be fixed. After the wall brush frame 3 is fixed, its bottom will drive the rubber plate 72 to move downward, and the rubber plate 72 drives the damper 73 and the spring 1 74 to be compressed. At the same time, the damper 73 and the spring 1 74 can buffer the wall brush frame 3.

[0034] After the wall brush frame 3 is fixed, the troughing machine drives the troughing machine grab body 1 to move downward, and the troughing machine grab body 1 drives the wall brush frame 3 to move. When moving, the wall brush frame 3 first scrapes off the larger mud or concrete blocks attached to the ground wall joint surface through the scraper 41, and then cleans it with a wire brush 43. After cleaning, tighten the bolt 45 to release the fixation between the pressure plate 44 and the U-shaped placement plate 42, and then the wire brush 43 can be disassembled, replaced and cleaned.

[0035] When disassembling the wall brush frame 3, it is only necessary to start the dual-axis motor 2 111 in reverse to move the blocking block 114 back to the inner cavity of the shell 8, and then start the dual-axis motor 1 61. The two output shafts of the dual-axis motor 1 61 drive the short rod 62 to rotate, and the short rod 62 drives the adjustment block 63 to make an arc motion with one side as the center of the circle, and the other side of the adjustment block 63 drives the wall brush frame 3 to move upward, so that the user can easily pick up the wall brush frame 3.
