Description

Technical Field

[0001] The utility model relates to the field of TRD pile construction protection, in particular to a protection device based on a TRD pile construction mixer. Background Art

[0002] The TRD pile construction mixer, also known as the TRD method pile construction mixer, utilizes a specialized cutting box to cut the ground and simultaneously inject cement slurry to form a continuous wall of uniform thickness. Its operating principle is to insert a chain saw-shaped blade port vertically into the ground, connect the blade and chain saw, and simultaneously move the blade sideways to cut a trench. A solidifying liquid (such as cement slurry) is then injected, mixed with the in-situ soil, and thoroughly stirred until it solidifies to form a uniform continuous cement-soil wall.

[0003] However, the existing TRD pile construction mixer does not have a mud isolation function during use, which makes it impossible to isolate and protect the outer surface of the end. Therefore, when the knife chain saw is running, mud blocks will be brought out, and the mud blocks will fall and hit the mud pool below. Part of the mud will splash onto the outer surface of the end of the TRD pile construction mixer, contaminating the outer surface of the mixer end and causing rust problems on the mixer end, thereby affecting the appearance of the mixer and affecting the normal use of the mixer. Utility Model Content

[0004] The purpose of the utility model is to provide a protective device based on a TRD pile construction mixer to solve the following technical problem: how to ensure that the splashing pollution of mud is isolated when the mixer is running.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 5 As shown, the utility model is a protective device based on a TRD pile construction mixer, comprising a limiting component 1 and a shielding component 2, wherein the shielding component 2 is movably mounted on the top of the limiting component 1;

[0026] The limiting component 1 includes a limiting frame 18, a driving motor 12 is symmetrically provided on the top of the limiting frame 18, one end of the driving motor 12 is fixedly connected to the driving gear 13, a delivery transverse pipe 11 is fixedly installed on one side of the upper part of the limiting frame 18, and limiting vertical rods 19 are provided on both sides of the limiting frame 18. The top center of the delivery transverse pipe 11 is fixedly connected to the delivery vertical pipe 14, the bottom of the delivery vertical pipe 14 is fixedly connected to the water supply pump 15, and the bottom of the water supply pump 15 is fixedly connected to the water tank 17, the top of the water tank 17 is symmetrically provided with a water filling port 16, and cleaning nozzles 110 are evenly provided on the bottom of the delivery transverse pipe 11. Cleaning grooves 111 are provided at both ends of the upper part of the limiting frame 18, and a limiting shaft hole 112 is provided on the upper part of the limiting frame 18 and between the delivery transverse pipe 11 and the limiting frame 18;

[0027] The shielding component 2 includes a winding shaft 25 , both ends of which are fixedly connected to transmission gears 24 , a shielding curtain 23 is wound on the outer surface of the winding shaft 25 , and a sinking plate 21 is fixedly connected to the bottom of the shielding curtain 23 .

[0028] The two ends of the winding shaft 25 of the utility model are rotatably connected to the top of the limit frame 18 through the cleaning groove 111, which can limit the rotation of the winding shaft 25. The driving motor 12 is meshed with the transmission gear 24 through the driving gear 13, and can control the forward and reverse rotation of the winding shaft 25 when the driving motor 12 is running. The two ends of the sinking plate 21 are fixedly connected to the limit ring 22, which can make the two ends of the sinking plate 21 slide and be connected to the outer surface of the limit vertical rod 19 to ensure that the sinking plate 21 does not deviate when it is raised or lowered.

[0029] The sinking plate 21 of the utility model is slidably connected to the outer surface of the limiting vertical rod 19 through the limiting rings 22 at both ends, ensuring the stability of the lifting and lowering of the shielding curtain 23. The shielding curtain 23 is connected to the top of the limiting frame 18 through the limiting shaft hole 112, which can enable the limiting shaft hole 112 to further clean the surface of the lifted shielding curtain 23. The bottom end of the cleaning nozzle 110 is inclined to point to the outer surface of the shielding curtain 23, which can ensure that the sprayed cleaning water flushes the surface of the shielding curtain 23.

[0030] The working principle of the present invention is as follows: first, the protective device is installed on the construction end of the TRD pile construction mixer by fastening screws, so that the cutter chain and the mixer can be separated. Then, before the TRD pile construction mixer is operated, the driving motor 12 is started first to drive the meshing transmission gear 24 to rotate through the driving gear 13 at one end. At the same time, the transmission gear 24 will drive the reel-up shaft 25 to unwind the shielding curtain 23, and the bottom end of the shielding curtain 23 will synchronously drop under the traction of the weight of the sinking plate 21 until the bottom surface of the sinking plate 21 contacts the bottom upper surface of 28. Then the TRD pile construction mixer can be started for construction. While the TRD pile construction mixer is running, mud will be generated and rise with the cutter chain, and finally fall and splash mud. Since the shielding curtain 23 is unfolded in advance, it can prevent the splashed mud from contacting the outer surface of the end of the TRD pile construction mixer, thereby protecting the outer surface of the end of the mixer. After the construction mixer is completed and stops running, the shielding curtain 23 needs to be stored. First, start the water supply pump 15 to extract the clean water from the water tank 17, and then transport the water to the inside of the delivery horizontal pipe 11 through the delivery vertical pipe 14. Finally, the clean water under high pressure will be sprayed on the outer surface of the shielding curtain 23 through the cleaning nozzle 110. At the same time, start the drive motor 12 to run in the reverse direction, thereby driving the reeling shaft 25 to reel the shielding curtain 23. As the shielding curtain 23 rises, the water sprayed by the cleaning nozzle 110 can remove the adhered mud. At the same time, when the shielding curtain 23 rises, due to the limit shaft hole 112 The inner side of the bottom contacts the shielding curtain 23, which will clean the surface of the shielding curtain 23 and prevent excessive water from adhering to the surface of the shielding curtain 23. At the same time, it can remove more stubborn mud stains, thereby ensuring that the shielding curtain 23 is clean and completely rolled up. Therefore, through the coordinated operation of the limiting component 1 and the shielding component 2 at the end of the mixer, the splashed mud can be isolated to prevent the mud from contaminating the outer surface of the end of the mixer, and the surface mud from adhering to the end of the mixer for a long time to cause rust, affecting the normal operation of the mixer.

[0031] The above describes an embodiment of the present invention in detail. However, the content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
