Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mold cleaning technology, and more specifically, it relates to a shield tunnel segment mold cleaning device. Background Technology
[0002] When cleaning shield tunnel segment molds, which require extremely high surface quality and cleanliness, the molds need to be placed in an ultrasonic cleaning tank. An ultrasonic generator produces high-frequency oscillation signals, which are converted into mechanical vibrations by a transducer and then transmitted to the cleaning fluid. In the cleaning fluid, the high-frequency vibration of the ultrasonic waves generates countless tiny bubbles. These bubbles grow and burst rapidly near the surface of the mold, generating powerful impact forces and micro-jet streams, thereby peeling off concrete residues, dirt, and other impurities from the surface of the mold.
[0003] Based on the above, during the cleaning process, impurities peeled off from the mold surface will gradually mix into the cleaning fluid. When the cleaning fluid is heavily contaminated, it needs to be discharged from the cleaning tank through the drain pipe. However, the concrete residue carried in the cleaning fluid is prone to deposit in the drain pipe during the discharge process, causing blockage and affecting the discharge efficiency of the cleaning fluid. The drain pipe needs to be cleaned manually, resulting in a heavy workload for the staff. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a shield tunnel segment mold cleaning device. This device solves the problem that during the cleaning process, impurities peeled off the mold surface gradually mix into the cleaning fluid. When the cleaning fluid is heavily contaminated, it needs to be discharged from the cleaning tank through a drain pipe. However, concrete residue carried in the cleaning fluid easily accumulates in the drain pipe during discharge, causing blockage and affecting the discharge efficiency of the cleaning fluid. This necessitates manual cleaning of the drain pipe, resulting in a heavy workload for workers.
[0005] The purpose and effectiveness of this utility model's shield tunnel segment mold cleaning device are achieved through the following specific technical means:

The ultrasonic cleaning tank is fixedly connected to the lower part of the limiting support frame. The transfer structure is disposed on the upper part of the limiting support frame. The sewage discharge pipe is fixedly connected to the left side of the ultrasonic cleaning tank. Two anti-deposition sliding plates are provided, and the two anti-deposition sliding plates are respectively slidably connected to the front and rear sides of the sewage discharge pipe.

Two positioning mounting plates are provided, and the two positioning mounting plates are respectively fixedly connected to the front and rear sides of the limiting mounting shaft.
[0007] Furthermore, the transfer structure includes a hoist trolley and a position limiting hook; the hoist trolley is slidably connected to the upper part of the limiting support frame; two position limiting hooks are provided, and the two position limiting hooks are respectively provided on the left and right sides of the hoist trolley.
[0008] Furthermore, the transfer structure also includes a mold lifting basket and position limiting rings; two position limiting rings are provided, and the two position limiting rings are respectively suspended from the lower part of the two position limiting hooks; the mold lifting basket is fixedly connected to the lower end face of the two position limiting rings.
[0009] Furthermore, the transfer structure also includes guide connecting rods, buffer rubber blocks, and limiting support sleeves; multiple guide connecting rods are provided, and the multiple guide connecting rods are evenly distributed and fixedly connected to the lower part of the mold lifting basket; multiple buffer rubber blocks are provided, and the multiple buffer rubber blocks are respectively fixedly connected to the upper end face of the multiple guide connecting rods; multiple limiting support sleeves are provided, and the multiple limiting support sleeves are respectively sleeved on the outside of the multiple guide connecting rods, and the multiple limiting support sleeves are respectively fixedly connected to the upper end face of the multiple buffer rubber blocks.
[0010] Furthermore, the mixing structure includes impurity mixing rods and reset elastic elements; multiple impurity mixing rods are provided, and the multiple impurity mixing rods are evenly distributed and fixedly connected to the upper and lower sides of the two anti-deposition sliding plates; multiple reset elastic elements are provided, and the two anti-deposition sliding plates are elastically connected to the sewage discharge pipe through the multiple reset elastic elements respectively.

[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] This invention uses a guide connecting rod and a limiting support sleeve to keep the bottom of the mold away from the mold lifting basket, avoiding the difficulty in cleaning the contact area between the mold and the mold lifting basket, thus ensuring the cleaning effect of the mold. A buffer rubber block cushions the vibrations experienced during mold transfer, effectively reducing the impact force on the mold, thereby reducing wear on the bottom of the mold and extending its service life. The convenient lifting mechanism allows for easy removal of the mold or placement into the ultrasonic cleaning tank, reducing the difficulty of mold transfer and improving cleaning efficiency. An anti-deposition sliding plate and an impurity mixing rod agitate the discharged cleaning fluid, reducing the deposition of residues in the cleaning fluid and preventing blockage of the drain pipe, thus improving the discharge efficiency of the cleaning fluid, reducing the need for manual cleaning of the drain pipe, and lowering the workload of the workers.
