Because the engineering construction construction field carries the elephant trunk demand very big to the concrete gravity type, in vertical transport, lack convenient durable buffer, to reduce transmission and concrete transmission speed, prolong elephant trunk application life, concrete aggregate after guaranteeing to carry is even, does not emanate, and guarantees inventory.For this reason, this problem is badly in need of being resolved.
The utility model content
The technical problems to be solved in the utility model provide a kind ofly reduce transmission and concrete transmission speed, prolong elephant trunk application life, the concrete aggregate after guaranteeing to carry evenly, do not emanate, guarantee the concrete elephant trunk buffer of inventory.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of concrete elephant trunk buffer, comprise buffering chute-pipe and be installed in the buffering chute-pipe last bell and spigot joint at two ends up and down respectively, following bell and spigot joint, last bell and spigot joint and following bell and spigot joint are along the coaxial corresponding setting of the length direction of buffering chute-pipe, the described buffering chute-pipe wherein middle part of a side caves inward, the longitudinal section of recess is side openings " mouth " font, this depression and last bell and spigot joint, coaxial corresponding setting of following bell and spigot joint, the top of buffering chute-pipe sunken inside is provided with the first-level buffer material trough, and the bottom in the buffering chute-pipe is provided with the level 2 buffering material trough.
As preferably, describedly go up the top of bell and spigot joint, the bottom of bell and spigot joint is separately installed with flange down.
As preferably, the longitudinal section of described first-level buffer material trough and level 2 buffering material trough all is " mouth " font of top opening.
As preferably, described buffering chute-pipe is a rectangular shape.
Further, the top of described buffering chute-pipe is equipped with anti-blocking cover plate.
Further, the described buffering chute-pipe bottom that is positioned at depression outward also is equipped with anti-blocking cover plate.
Compared with prior art, the beneficial effects of the utility model are: reasonable in design, reduced concrete transporting velocity, the wearing and tearing of elephant trunk system have been reduced, prolong the application life of elephant trunk, prevented concrete Segregation, improved concrete workability, guaranteed the concrete mixing amount, and the device that this programme designs durable in use, be easy to repair and maintenance.The utility model can be used for the vertical from falling to carrying of concrete or similar material.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model embodiment;
Fig. 2 is the workflow diagram of the utility model embodiment.
Among the figure: 1-buffering chute-pipe, the last bell and spigot joint of 2-, bell and spigot joint under the 3-, 4-first-level buffer material trough, 5-level 2 buffering material trough, the anti-blocking cover plate of 6-, 7-flange, 8-elephant trunk.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Embodiment:
As shown in Figure 1, a kind of concrete elephant trunk buffer comprises buffering chute-pipe 1 and is installed in the last bell and spigot joint 2 at buffering chute-pipe two ends about in the of 1, following bell and spigot joint 3 respectively, and last bell and spigot joint 2 and following bell and spigot joint 3 are along the coaxial corresponding setting of the length direction of buffering chute-pipe 1.The top of described upward bell and spigot joint 2, the bottom of following bell and spigot joint 3 are separately installed with flange 7.Described buffering chute-pipe 1 is a rectangular shape.The described buffering chute-pipe 1 wherein middle part of a side caves inward, and the longitudinal section of recess forms " mouth " font of side openings, this depression and last bell and spigot joint 2, bell and spigot joint 3 coaxial corresponding settings down.The top of described buffering chute-pipe 1 sunken inside is provided with first-level buffer material trough 4, and the bottom in the buffering chute-pipe 1 is provided with level 2 buffering material trough 5.The longitudinal section of described first-level buffer material trough 4 and level 2 buffering material trough 5 all is " mouth " font of top opening.The top of described buffering chute-pipe 1 is equipped with anti-blocking cover plate 6, and the buffering chute-pipe 1 outer bottom that is positioned at depression also is equipped with anti-blocking cover plate 6, and anti-blocking cover plate 6 is all by being bolted to the corresponding site of buffering chute-pipe 1.
In the present embodiment, last bell and spigot joint 2 and following bell and spigot joint 3 achieve a fixed connection by bolt flange 7 with the elephant trunk system of outside, convenient installation, dismounting; Adopt the mode of double reduction buffering, possess simultaneously and slow down and stirring action; The deceleration impact site adopts the design of cushion hopper, effectively avoids the impact failure of concrete (material) to buffer, has prolonged its application life greatly; The bolt that is provided with connects anti-blocking cover plate 6, and mediation is safeguarded when conveniently stopping up once in a while.
As shown in Figure 2, the workflow of present embodiment is as follows:
This device is connected with the elephant trunk 8 of top and bottom respectively by last bell and spigot joint 2, following bell and spigot joint 3, after concrete (material) is gone up bell and spigot joint 2 certainly and is entered this device, impact first-level buffer material trough 4 and carry out the deceleration buffer first time, and turn to and enter buffering chute-pipe 1 inside, mix down at material, continue to impact level 2 buffering material trough 5 and carry out the deceleration buffer second time, and turn to the elephant trunk 8 that enters the lower end once more, finish concrete (material) deceleration buffer and stirring.When whole elephant trunk system was provided with buffer, we can be provided with a concrete elephant trunk buffer every 20m-40m, like this can be within the range of permission with the control of transmission and concrete transmission speed, and can guarantee that concrete aggregate does not separate, do not emanate.If stop up owing to reasons such as concrete mixing mass deviation cause buffer, available spanner is opened anti-blocking cover plate 6, stretches into vibrator or iron staff, knocks this buffer simultaneously, dredges maintenance.
Adopt the utility model, can avoid concrete vertical transport drop greatly to the influence of concrete quality and safety, in the whole elephant trunk of design system, the spacing maximum between adjacent two concrete elephant trunk buffers can be set to 50 meters.
