Technical Field
[0001] This utility model relates to the field of building engineering, and in particular to a concrete pipe pile excavation device for building engineering. Background Technology
[0002] Construction engineering refers to the engineering entities formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. It includes the construction, renovation, and expansion of buildings, as well as related decoration and repair work. It is an important branch of civil engineering, closely related to people's production and life, and occupies an important position in the national economic development.
[0003] In building construction, concrete pipe piles are widely used in foundation engineering due to their advantages such as high bearing capacity, high construction efficiency, and relatively low cost. However, after the pipe pile construction is completed, due to design adjustments, construction errors, or changes in geological conditions, it is often necessary to remove the concrete on the top or inside of the pipe pile to meet the needs of subsequent pile cap construction, pile head treatment, or equipment installation. This process is called "pile removal". However, existing pile-pulling machines are manually operated by people when rotating at high speed or performing impact operations. As a result, the pile-pulling machine will generate vibrations during operation, which will prevent the concrete pipe from being hollowed out accurately during the pile-pulling process. This will cause the pile-pulling machine to deviate due to vibration, resulting in deviations in the pile-pulling position. Therefore, a pile-pulling device for concrete pipe piles in building engineering is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a concrete pipe pile excavation device for building engineering, which aims to improve the problem that the existing pile excavation machine will generate vibration during operation, which will cause the concrete pipe to be inaccurately excavated during the pile excavation process, and the pile excavation machine will easily deviate due to vibration, resulting in deviation of the pile excavation position.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A concrete pipe pile excavation device for building construction includes a limiting ring, a limiting frame fixedly installed on the surface of the limiting ring, a connecting plate provided on the top of the limiting ring, a motor fixedly installed on the top of the connecting plate, a rotating rod fixedly installed on the output end of the motor, the bottom of the rotating rod penetrating to the bottom of the limiting ring, and a support component for supporting the connecting plate provided inside the limiting frame. As a further description of the above technical solution: The support assembly includes three sets of limiting blocks, the limiting blocks and the limiting frame are slidably installed, the top of the limiting block is movably installed with a limiting sleeve, the surface of the connecting plate is fixedly installed with a fixing block, and the inside of the limiting sleeve and the surface of the fixing block are movably installed. As a further description of the above technical solution: A limiting rod is fixedly installed inside the limiting frame. The limiting rod and the limiting block are slidably installed. A spring is sleeved on the surface of the limiting rod. The outer end of the spring is fixedly installed on the inner wall of the limiting frame. The inner end of the spring is fixedly installed on the outer side of the limiting block. As a further description of the above technical solution: The top of the limiting frame is provided with a fixing groove, and a bolt is slidably installed inside the fixing groove. The bottom of the bolt extends through to the bottom of the limiting frame. An inclined block is movably installed inside the fixing groove, and the top of the inclined block contacts the bottom of the inner wall of the bolt. As a further description of the above technical solution: A tension spring is fixedly installed at the bottom of the inner wall of each set of fixing grooves, with the top of the tension spring and the bottom of the inclined block fixedly installed, and the bottom of the tension spring and the bottom of the inner wall of the fixing groove fixedly installed. As a further description of the above technical solution: A protective cover is fixedly installed on the top of the connecting plate, and the motor is located inside the protective cover; As a further description of the above technical solution: A handle is fixedly installed on the surface of the protective cover, and the handle is used in conjunction with the protective cover.
[0006] This utility model has the following beneficial effects: In this invention, when the bottom of the limiting ring contacts the ground, the bottom of the limiting frame also contacts the ground. Then, the bolt can be pushed to the bottom, and the bolt will enter the soil to limit the limiting frame, thereby improving the stability of the overall device during operation. When the work is finished, the inclined block can be pressed down, and the inclined block will lift the bolt, so that the bolt can be easily removed from the soil.
[0007] In this invention, the tension spring provides a restoring force to the inclined block. When the bolt enters the soil, the tension spring pulls one side of the inclined block to contact the inner wall of the fixing groove, thereby preventing the inclined block from being subjected to external force and causing the bolt and soil to shake.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0011] Reference Figure 1-4 This utility model provides an embodiment of a concrete pipe pile excavation device for building engineering, including a limiting ring 1, a limiting frame 2 fixedly installed on the surface of the limiting ring 1, a connecting plate 3 provided on the top of the limiting ring 1, a motor 4 fixedly installed on the top of the connecting plate 3, a rotating rod 5 fixedly installed on the output end of the motor 4, the bottom of the rotating rod 5 extending through to the bottom of the limiting ring 1, and a support component 6 for supporting the connecting plate 3 provided inside the limiting frame 2. By setting the limiting frame 2 on the surface of the limiting ring 1 and connecting the connecting plate 3 with the motor 4 to the top of the limiting ring 1, and using the support component 6 inside the limiting frame 2 to support the connecting plate 3, the stability of the motor 4 and the rotating rod 5 during operation can be effectively ensured. The support component 6 can evenly distribute the load borne by the connecting plate 3, avoid the problem of reduced transmission efficiency of the motor 4 due to shaking, and enable the rotating rod 5 to maintain accurate axial positioning when rotating at high speed to excavate the pile, thereby improving the efficiency and accuracy of the excavation operation.
[0012] Reference Figure 1-4The support assembly 6 includes three sets of limiting blocks 61. The limiting blocks 61 and the limiting frame 2 are slidably installed. A limiting sleeve 62 is movably installed on the top of the limiting block 61. A fixing block 63 is fixedly installed on the surface of the connecting plate 3. The inside of the limiting sleeve 62 and the surface of the fixing block 63 are movably installed. The support assembly 6 uses three sets of slidably installed limiting blocks 61, which, together with the limiting sleeve 62, are movably connected to the fixing block 63 on the connecting plate 3 to form a dynamically adjustable support structure. The limiting block 61 can slide within the limiting frame 2 to accommodate the slight displacement that the connecting plate 3 may produce during operation. Through the movable cooperation between the limiting sleeve 62 and the fixing block 63, the radial displacement of the connecting plate 3 can be limited, while allowing it to be adjusted in angle within a certain range. The limiting frame 2... The internal fixed installation includes a limiting rod 64, which is slidably installed with the limiting block 61. A spring 65 is sleeved on the surface of the limiting rod 64. The outer end of the spring 65 is fixedly installed on the inner wall of the limiting frame 2. The inner end of the spring 65 is fixedly installed on the outer side of the limiting block 61. When the pile excavation work is carried out, the motor 4 can be pressed down to the bottom. The motor 4 drives the rotating rod 5 to move to the bottom. The motor 4 also drives the connecting plate 3 to move to the bottom. The movement of the connecting plate 3 to the bottom drives the limiting sleeve 62 to move outward. The movement of the limiting sleeve 62 to move outward drives the limiting block 61 to move outward. The movement of the limiting block 61 to move outward can compress the spring 65, thereby improving the stability of the limiting ring 1 when it is limited, and also reducing the vibration generated by the motor 4 when it is working.
[0013] Reference Figure 1-4The top of the limiting frame 2 is provided with a fixing groove 66. A bolt 67 is slidably installed inside the fixing groove 66, and the bottom of the bolt 67 extends through to the bottom of the limiting frame 2. An inclined block 68 is movably installed inside the fixing groove 66. The top of the inclined block 68 contacts the bottom of the inner wall of the bolt 67. When the bottom of the limiting ring 1 contacts the ground, the bottom of the limiting frame 2 will also contact the ground. Then, the bolt 67 can be pushed to the bottom, and the bolt 67 will enter the soil to limit the limiting frame 2, thereby improving the stability of the overall device during operation. After the work is completed, the inclined block 68 can be pressed down, and the inclined block 68 will lift the bolt 67, so that the bolt 67 can be easily removed from the soil. A tension spring 69 is fixedly installed at the bottom of the inner wall of each fixing groove 66. The top of the tension spring 69 is fixedly installed at the bottom of the inclined block 68, and the bottom of the tension spring 69 is fixedly installed at the bottom of the inner wall of the fixing groove 66. The tension spring 69 provides a restoring force to the inclined block 68. When the bolt 67 enters the soil, the tension spring 69 pulls one side of the inclined block 68 to contact the inner wall of the fixing groove 66, thereby preventing the inclined block 68 from being subjected to external force and causing the bolt 67 and the soil to shake. A protective cover 7 is fixedly installed on the top of the connecting plate 3. The motor 4 is located inside the protective cover 7. The protective cover 7 provides a reliable protective barrier for the motor 4, which can effectively block concrete debris, dust and splashing mud generated during the pile excavation process, prevent the motor 4 windings and bearings from being damaged by contamination, and extend the service life of the motor 4. A handle 8 is fixedly installed on the surface of the protective cover 7. The handle 8 and the protective cover 7 work together. The operator can easily move and adjust the position of the device through the handle 8. Moreover, when the whole device is working, the operator also needs to manually press down the handle 8, so that the rotating rod 5 can enter the soil more stably.
[0014] Working principle: When pile excavation is required, the limiting ring 1 can be brought into contact with the ground, and the bottom of the limiting frame 2 will also be in contact with the ground. The bolt 67 can be pressed down to the bottom, and the bolt 67 will enter the soil, thus limiting the limiting ring 1. Then, the handle 8 can be pressed down to the bottom. The handle 8 moves to the bottom, which moves the protective cover 7 to the bottom. The protective cover 7 moves to the bottom, which moves the motor 4 and the connecting plate 3 to the bottom. The motor 4 can be started at this time. The output end of the motor 4 can drive the rotating rod 5 to rotate. The connecting plate 3 moves to the bottom, which moves the limiting sleeve 62 to the outside. The limiting sleeve 62 moves to the outside, which moves the limiting block 61 to the outside. The limiting block 61 moves to the outside, which can compress the spring 65. At this time, the pile excavation can be carried out stably under the action of the rotating rod 5. After the pile excavation is completed, the inclined block 68 can be pressed down to the outside. The inclined block 68 moves outward and lifts the bolt 67. Then, the handle 8 can be pulled up to the top, and the handle 8 can drive the whole thing to reset.
[0015] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
