DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0027] The following will be described in detail with reference to the drawings in the embodiments of the application. Figures 1-4 The embodiments of the application will be further described in detail.

[0028] Embodiment 1

[0029] Please refer to Figures 1-4 The embodiment provides a technical solution: a cement soil mixing station water inlet pipe anti-falling device, which comprises a first positioning block 1, a second positioning block 2, a sealing ring 3 and a fixing mechanism 4.

[0030] The top view of the first positioning block 1 is a semicircular arc, the cross section of the first positioning block 1 is a "C" shape, and the inner wall of the first positioning block 1 is provided with an arc-shaped groove. The first positioning block 1 can be sleeved on the outer wall of the flange plate connected to the water inlet pipe. The arc-shaped groove of the first positioning block 1 can limit the upper and lower ends of the flange plate connected to the water inlet pipe, avoiding the phenomenon of shaking. The second positioning block 2 is arranged on the outer wall of the first positioning block 1. The second positioning block 2 can be sleeved on the outer wall of the flange plate connected to the water inlet pipe. The shape of the second positioning block 2 is consistent with that of the first positioning block 1. The first positioning block 1 and the second positioning block 2 can be fitted on the outer wall of the flange plate, thereby limiting and fixing the flange plate. The sealing ring 3 is bonded inside the arc-shaped groove of the first positioning block 1 and the second positioning block 2. After the first positioning block 1 and the second positioning block 2 are sleeved on the outer wall of the connection of the flange plate, the sealing ring 3 is extruded on the connection of the flange plate, thereby achieving effective sealing effect.

[0031] The fixing mechanism 4 is arranged on the outer wall of the first positioning block 1 and the second positioning block 2. The fixing mechanism 4 can provide effective stability for the flange plate of the water inlet pipe, avoiding the phenomenon of loosening caused by shaking of the water inlet pipe after being connected to the cement soil mixing station. The fixing mechanism 4 includes a first bolt 401 vertically welded above the first positioning block 1 and the second positioning block 2. The first bolt 401 is composed of a bolt and a nut. The first bolt 401 is welded above the bolt first positioning block 1 and the second positioning block 2, which can provide the structure outside the first bolt 401 to realize angle change and position adjustment. The limiting block 402 is rotatably connected to the outside of the first bolt 401. The limiting block 402 is provided with a rectangular hole in the inside. The limiting block 402 can realize angle change and position adjustment on the first bolt 401 through the rectangular hole. When the limiting block 402 is located on the fastener in the flange plate, the fastener can be prevented from loosening and moving.

[0032] When the water inlet pipe is connected to the cement soil mixing station through the fastener in the flange plate, the first positioning block 1 and the second positioning block 2 are horizontally sleeved on the outer wall of the flange plate, so that the outer walls of the first positioning block 1 and the second positioning block 2 are fitted. At this time, the sealing ring 3 in the first positioning block 1 and the second positioning block 2 will increase the sealing effect of the gap at the connection of the flange plate. Then the limiting block 402 is rotated through the first bolt 401, so that one end of the limiting block 402 is rotated and displaced above the fastener of the flange plate, avoiding the phenomenon of loosening of the fastener of the flange plate caused by shaking during the work of the cement soil mixing station.

[0040] Secondly, by rotating the connecting shaft 405 in the through hole 404 of the second positioning block 2, the connecting shaft 405 will synchronously drive the fixed block 406 on the connecting shaft 405 to change the angle in the first slot 403, and at this time, the second bolt 407 in the fixed block 406 will drive the second bolt 407 to rotate and displace to the inside of the second slot 408 of the first positioning block 1, and by rotating the second bolt 407, the second bolt 407 will be displaced after the fixed block 406 rotates, and at this time, one end of the second bolt 407 is pressed against the outer wall of the first positioning block 1, so that the first positioning block 1 and the second positioning block 2 are fixedly connected.

[0041] Finally, the limiting block 402 is rotated by the first bolt 401, so that one end of the limiting block 402 is displaced to above the fastener of the flange plate, so as to avoid loosening of the fastener of the flange plate due to shaking during work of the cement soil mixing station.
