Description

Technical Field

[0001] The utility model relates to the technical field of roadbed opening mechanism design, in particular to a opening mechanism for reinforcing a muddy stratum roadbed. Background Art

[0002] Silt foundation is a common foundation problem, which usually causes instability and safety hazards to buildings or projects. The key to solving the silt foundation problem is to reinforce the foundation and improve the bearing capacity and stability of the foundation. The reinforcement of the silt foundation inevitably requires drilling holes in the silt. However, in the prior art, the existing common silt foundation drilling operations, due to the very soft silt soil, will cause a large amount of silt to flow back into the newly opened slots, resulting in the need for multiple continuous drillings, which increases the burden of the drilling operations. Utility Model Content

[0003] The utility model aims to solve the problem in the prior art that the slot holes opened will suffer from a large amount of silt backflow, affecting the progress of silt foundation reinforcement, and proposes a hole opening mechanism for silt stratum roadbed reinforcement.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a hole-opening mechanism for reinforcing a roadbed in a silt formation, comprising a servo motor, a connecting rod is arranged at one end of the servo motor, a Jiaolong blade is fixedly connected to the surface of the connecting rod, a fixed tooth block is fixedly connected to the bottom of the connecting rod, a side tooth ring is fixedly connected to the outer surface of the fixed tooth block, a telescopic rod is arranged at one end of the servo motor, a connecting clamp is fixedly connected to the surface of the telescopic rod, a connecting block is fixedly connected to the surface of the connecting clamp, a connecting ring is fixedly connected to one end of the connecting block, a screw is penetrated and connected to the inner wall of the connecting ring, a clamp ring is arranged on the surface of the screw, a reinforcement barrel is arranged on one side of the servo motor, a pointed rod is fixedly connected to the bottom of the reinforcement barrel, a clamp block is fixedly connected to the inner wall of the reinforcement barrel, one end of the clamp block is fixedly connected to the fixing ring, and a telescopic cylinder is arranged at one end of the telescopic rod.

[0005] As a preferred implementation, a card slot is provided inside the card block, and the outline of the card slot provided inside the card block is matched with the outer outline of the connecting card plate.

[0006] The technical effect of adopting the above further solution is that the connecting card plate can be directly inserted into the card slot opened inside the card block, so that the reinforcement barrel can slide along the surface of the connecting card plate.

[0007] As a preferred embodiment, the surface of the screw is provided with threads, and the inner wall of the clamping ring is provided with thread grooves meshing with the threads on the surface of the screw.

[0008] The technical effect of adopting the above further scheme is: the thread groove opened on the inner wall of the clamping ring engages with the thread on the surface of the screw, so that the screw passes through and is connected to the inside of the connecting ring and the fixing ring, and the screw and the clamping ring indirectly fix the connecting clamping plate and the clamping block.

[0009] As a preferred implementation, a circle of latching teeth is provided at the bottom end of the fixed tooth block, and two side tooth rings are fixedly connected to the outer wall of the fixed tooth block.

[0010] The technical effect of adopting the above further scheme is: the two side tooth rings are fixedly connected to the outer surface of the fixed tooth block, which increases the sharpness of the bottom of the device, and at the same time the locking teeth on the bottom of the fixed tooth block and the surface of the side tooth ring can quickly open holes in the ground.

[0011] As a preferred implementation manner, the interior of the servo motor is rotatably connected to one end of the connecting rod.

[0012] The technical effect of adopting the above further scheme is: the servo motor is rotationally connected to one end of the connecting rod, and at the same time drives the dragon blades on the surface of the connecting rod and the fixed tooth blocks and side tooth rings fixedly connected to the bottom of the connecting rod to rotate simultaneously, thereby opening a hole in the ground.

[0013] As a preferred implementation, the two side edges of the clamping block are respectively fixedly connected to fixing rings, and the internal opening of the fixing ring is adapted to the diameter of the screw.

[0014] The technical effect of adopting the above further solution is: it is convenient for the screws to directly penetrate the interior of the fixing ring to fix the reinforcement barrel, thereby preventing the reinforcement barrel from slipping.

[0015] Compared with the prior art, the advantages and positive effects of the utility model are:

[0016] In the utility model, by designing structures such as fixed tooth blocks and reinforcement barrels, the servo motor is started to drive the connecting rod and the dragon blades, fixed tooth blocks and side tooth rings connected to the surface of the connecting rod to rotate quickly, so as to quickly open a hole in the mud ground. The telescopic rod and the connecting clamping plate are moved upward by the telescopic cylinder, so that the reinforcement barrel gradually sinks to the bottom of the mud ground. The reinforcement barrel stabilizes the area where the hole is opened to prevent the soft silt from flowing into the newly opened hole again, avoiding the situation of large-scale silt backflow, and at the same time reducing the number of times of opening holes, making the roadbed of the silt section more stable.

[0027] In this embodiment, by designing structures such as the Jiaolong blade 21 and the fixed tooth block 3, the bottom teeth of the fixed tooth block 3 and the teeth at the edge of the side tooth ring 31 rotate at high speed on the muddy ground, so that the connecting rod 2 and the Jiaolong blade 21 can quickly open a hole downward, thereby increasing the speed of the equipment to open the hole and improving the efficiency of the roadbed reinforcement construction.

[0028] Example 2

[0029] like Figure 1-Figure 5 As shown, the inner wall of the connecting ring 51 is penetrated by a screw 6, the surface of the screw 6 is provided with a thread, the surface of the screw 6 is provided with a clamping ring 7, and the inner wall of the clamping ring 7 is provided with a thread groove meshing with the thread on the surface of the screw 6, so that the screw 6 and the clamping ring 7 are threadedly connected, and a reinforcement barrel 8 is provided on one side of the servo motor 1. The reinforcement barrel 8 can be embedded in the opened hole to reduce the infiltration of silt into the hole. The bottom of the reinforcement barrel 8 is fixedly connected with a pointed rod 81, and the bottom end of the pointed rod 81 is sharp, which first penetrates into the silt, so that The reinforcement barrel 8 can be stably embedded in the opened hole. A block 82 is fixedly connected to the inner wall of the reinforcement barrel 8.

At the same time, the bottom of the fixed tooth block 3 begins to quickly open a hole on the silt ground, and the connecting rod 2 and the dragon blade 21 gradually penetrate into the silt. The dragon blade 21 rotates at high speed through the servo motor 1 to soften the silt and bring the silt out of the ground.
