Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, specifically a simple device for manually excavating bored piles for existing railway lines. Background Technology

[0002] Existing lines refer to lines that have already been built. In the highway, railway, pipeline, cable or other transportation industries, existing lines usually refer to those lines that have been opened to traffic and are in operation. When it is necessary to build or renovate these lines, the original lines are called existing lines. When drilling piles on the basis of existing lines, in order to reduce the damage to the original structure during the construction process, manual construction methods are usually used.

[0003] Currently, in some manual bored pile excavation methods, workers need to use mud slurry and formwork to create a protective wall on the surface of the bored pile to facilitate subsequent excavation work and prevent the pile from collapsing. However, once the protective wall is formed, a connection is created between the formwork and the mud slurry, requiring workers to remove the formwork. This process is laborious, and for relatively stable formwork connections, it is inconvenient for workers to quickly remove the formwork, thus affecting the overall progress of the bored pile excavation work. Utility Model Content

[0004] The purpose of this utility model is to provide a simple device for manually excavating bored piles for existing railway lines, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a simple device for manually excavating bored piles for existing power lines, comprising a fixing ring, a connecting frame, and a rotating plate rotatably sleeved on the surface of the connecting frame, and further comprising:

[0006] A bracket is fixedly connected to the top of a fixed ring. A force-bearing mechanism is installed on the inner wall of the bracket.

The force-bearing plate is movably sleeved on the surface of the lead screw. One end of the first compression spring is fixedly connected to the bottom of the force-bearing plate, and a connecting bracket is installed on the top of the force-bearing plate.

[0009] Preferably, the lifting mechanism includes a lifting cylinder, a collar, and a pressure rod. The lifting cylinder is threaded onto the surface of the lead screw, the collar is fixedly connected to the bottom of the lifting cylinder, the pressure rod is fixedly connected to the bottom of the collar, and the connecting plate is rotatably sleeved on the surface of the lifting cylinder.

The two ends of the second light rod are fixedly connected to the two sides of the inner wall of the bracket, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In use, this utility model allows workers to first move the first and second arc-shaped plates through the cooperation of the lifting mechanism, connecting plate, and force-bearing mechanism, thereby releasing the contact between the first and second arc-shaped plates and the retaining wall. Subsequently, with the assistance of the auxiliary mechanism, the first and second arc-shaped plates descend, ready for subsequent bored pile operations.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4As shown, a simple device for manually excavating bored piles for existing power lines includes a fixed ring 1, a connecting frame 9, and a rotating plate 10 rotatably sleeved on the surface of the connecting frame 9. A bracket 2 is fixedly connected to the top of the fixed ring 1. A force-bearing mechanism 3 is installed on the inner wall of the bracket 2. A motor 4 is fixedly connected to the top of the bracket 2 and a lead screw 5 rotatably passes through it. The top of the lead screw 5 is fixedly connected to the output shaft of the motor 4. A lifting mechanism 6 is provided on the surface of the lead screw 5. A connecting plate 7 is rotatably sleeved on the surface of the lifting mechanism 6. There are several connecting frames 9 and rotating plates 10. One side of the connecting frame 9 is installed on the top of the connecting plate 7 and the force-bearing mechanism 3. A vertical plate 11 is installed on the surface of the other side of the connecting frame 9. A fixed plate 12 is fixedly connected to the bottom of the vertical plate 11. There are several vertical plates 11 and fixed plates 12. A top plate 13 is fixedly connected to the top of one side of the vertical plate 11. A first smooth rod 14 slides through the surface of the top plate 13. Extension plates 21 are fixedly connected to both sides of the bracket 2. The two ends of a light rod 14 are fixedly connected to the surfaces of two extension plates 21 respectively. Through the cooperation of the extension plates 21, the first light rod 14 and the top plate 13, the stability of one vertical plate 11 during movement can be increased. At the same time, the connecting plate 7 can also cooperate with the lifting mechanism 6 to move down stably. The surface of the other vertical plate 11 is fixedly connected to a side plate 15. The surface of the side plate 15 is slidably penetrated by a second light rod 16. The two ends of the second light rod 16 are fixedly connected to the two sides of the inner wall of the bracket 2 respectively. Through the cooperation of the fixing ring 1 and the second light rod 16, the stability of the other vertical plate 11 during movement can be increased. The bottom of the fixing plate 12 is fixedly connected to a hollow cylinder 17. The hollow cylinder 17 is provided with an auxiliary mechanism 18. There are several auxiliary mechanisms 18. The bottom of one auxiliary mechanism 18 is fixedly connected to a first arc plate 19, and the bottom of the other auxiliary mechanism 18 is fixedly connected to a second arc plate 20. The first arc plate 19 and the second arc plate 20 can cooperate to form a protective wall template.

[0022] The force-bearing mechanism 3 includes a horizontal plate 31, a first compression spring 32, and a force-bearing plate 33. The surface of the horizontal plate 31 is fixedly connected to the inner wall of the bracket 2. The first compression spring 32 is installed on the top of the horizontal plate 31. The force-bearing plate 33 is movably sleeved on the surface of the lead screw 5. One end of the first compression spring 32 is fixedly connected to the bottom of the force-bearing plate 33. A connecting frame 9 is installed on the top of the force-bearing plate 33. When the force-bearing plate 33 is subjected to force and descends, the connecting frame 9 on the top of the force-bearing plate 33 can drive the corresponding rotating plate 10 to rotate. The corresponding vertical plate 11 can drive the fixed plate 12 to move. The hollow cylinder 17 then drives the auxiliary mechanism 18 to move, and the second arc-shaped plate 20 can move.

[0023] The lifting mechanism 6 includes a lifting cylinder 61, a collar 62, and a pressure rod 63. The lifting cylinder 61 is threaded onto the surface of the lead screw 5. The collar 62 is fixedly connected to the bottom of the lifting cylinder 61. The pressure rod 63 is fixedly connected to the bottom of the collar 62. The bottom of the pressure rod 63 is in contact with the top of the force plate 33. When the operator starts the motor 4, the lead screw 5 can be rotated. The lifting cylinder 61 then drives the connecting plate 7 to descend. The connecting frame 9 at the top of the connecting plate 7 drives the rotating plate 10 to rotate. The vertical plates 11 on both sides of the connecting plate 7 drive the fixed plate 12 to descend. The corresponding hollow cylinder 17, in cooperation with the auxiliary mechanism 18, can drive the first arc plate 19 to move. The connecting plate 7 is rotated and sleeved onto the surface of the lifting cylinder 61.

[0024] The surfaces on both sides of the connecting plate 7 are provided with grooves 8, which are corresponding to the connecting frame 9 on the top of the force plate 33. Accordingly, when the force plate 33 descends, the grooves 8 can be used to rotate in conjunction with the rotating plate 10.

[0025] The auxiliary mechanism 18 includes a disc 181, an auxiliary rod 182, and a second compression spring 183. The surface of the disc 181 is slidably connected to the inner wall of the hollow cylinder 17. The auxiliary rod 182 is fixedly connected to the bottom of the disc 181 and slides through the bottom of the hollow cylinder 17. The first arc plate 19 is fixedly connected to the bottom of one side of the auxiliary rod 182, and the second arc plate 20 is fixedly connected to the bottom of the other side of the auxiliary rod 182. With the auxiliary mechanism 18, during the drilling of the bored pile, as the depth of the bored pile increases, the disc 181 can drive the auxiliary rod 182 to descend under the action of the elastic force of the second compression spring 183. At this time, the height of the first arc plate 19 and the second arc plate 20 can be adjusted so that the first arc plate 19 and the second arc plate 20 can be used in conjunction with the subsequent drilling operation.

[0026] Working principle: Workers install the fixing ring 1 on the ground. At this time, the bottoms of the first arc-shaped plate 19 and the second arc-shaped plate 20 contact the bottom of the inner wall of the bored pile. Workers can then use mud to form a protective wall between the surface of the first arc-shaped plate 19 and the bored pile wall, and between the surface of the second arc-shaped plate 20 and the bored pile wall, to ensure the smooth progress of subsequent bored pile excavation. Workers continue excavating based on the existing bored pile depth, and the mud used by the first and second arc-shaped plates 19 and 20 assists in forming the protective wall. After the existing bored pile has been excavated to a certain depth, the motor 4 is started. The lead screw 5 rotates and, through the lifting mechanism 6, lowers the connecting plate 7. During the descent, the connecting plate 7, through its top connecting frame 9, drives the corresponding rotating plate 10 to rotate, and the upper vertical plate 11... As the fixed plate 12 moves, the hollow cylinder 17 on one side drives the first arc plate 19 to move via the auxiliary mechanism 18. The contact between the first arc plate 19 and the second arc plate 20 is released. The lifting mechanism 6 continues to descend. When the pressure rod 63 contacts the force plate 33, it drives the force plate 33 to descend. The connecting frame 9 at the bottom of the force mechanism 3 drives the corresponding rotating plate 10 to rotate. The lower vertical plate 11 drives the fixed plate 12 to move. Thus, the hollow cylinder 17 and the auxiliary mechanism 18 can work together to drive the second arc plate 20 to move. The contact between the first arc plate 19 and the second arc plate 20 and the existing retaining wall is released. Under the action of the second compression spring 183, the bottom of the first arc plate 19 and the second arc plate 20 can contact the bottom of the inner wall of the bored pile, so that the subsequent bored pile operation can proceed normally.
