Description
Technical Field
[0001] The utility model relates to the technical field of compartment material distribution equipment, in particular to a rotary balanced pressure compartment material distribution device. Background Art
[0002] After the initial support of tunnel construction is completed, secondary lining, that is, pouring concrete, is required. Since the trolley is a large equipment, usually about 12 meters long, there are generally multiple rows and columns of windows staggered on both sides of the trolley for pouring concrete. Due to the easy coagulation and high density of concrete, a longer hard pipe is usually connected to the pump of the mixer, and then a shorter hose is connected to the pouring window when approaching the pouring window. The traditional method of pouring concrete usually stops the mixer and closes the pouring window after pouring concrete in one window, and then continues to pour concrete in another window with a hard pipe according to the length. Since this method requires changing the pipe, it has a large workload and takes a long time. When the next window starts to pour concrete, the concrete poured in the previous window may have begun to initially set, and the concrete poured in the two windows cannot be completely blended, so cold joints are easily produced. If you want to be lazy and use fewer windows for pouring, it is easier to produce a herringbone slope.
[0003] At present, there is a compartment system for pouring concrete, which can solve the above problems to a certain extent. The main method is to install a distributor on the platform, and then connect the feed pipe with the concrete flowing out of the mixer by pumping. That is, the concrete flowing out of the mixer is sent into the distributor through the feed pipe by the pressure of the pump, and then the distributor distributes the concrete to multiple distribution pipes, and then the distribution pipes are used to quickly pour the concrete into the corresponding tunnel windows. The equipment can quickly switch the pouring window, overcoming the problems of herringbone slope and cold joints that are easy to produce in the traditional pouring method. However, when the distribution pipe is inserted into the tunnel window for concrete pouring, the impact force generated during the concrete transportation may cause the distribution pipe to accidentally detach from the tunnel window when pouring concrete, resulting in failure of concrete pouring.
