Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a device for controlling the verticality of rotary drilling piles. Background Technology

[0002] In construction engineering, rotary drilling is a common pile foundation construction method used to increase the bearing capacity of the foundation or improve the stability of the foundation. Rotary drilling construction generally includes steps such as pile driver positioning, pile hole excavation, grouting or concrete pouring, and pile body inspection. The specific construction process and steps will be adjusted according to the project requirements and actual site conditions.

[0003] Currently, before drilling for grouting piles, rotary drilling rigs are often used. During the operation of rotary drilling rigs, they are easily affected by the surrounding terrain, which can cause the drill rod of the rotary drilling rig to be unable to be set vertically, thus affecting the drilling effect of the subsequent grouting piles. Utility Model Content

[0004] The purpose of this utility model is to provide a device for controlling the verticality of rotary drilling piles to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary drilling pile verticality control device, comprising a base plate, and further comprising:

[0006] Several fixing plates are fixed to the top of the base plate, and a fixing tube is fixed to the other end of the fixing plate. Several movable rods are movably connected to the surface of the fixing tube, and a guide plate is fixedly connected to one end of the movable rod.

[0007] A connecting rod is hinged to the other end of the movable rod; a support rod is hinged to the outside of the fixed plate; a fixed rod is fixedly connected to one side of the support rod; and the other end of the support rod is hinged to the other end of the connecting rod.

[0008] A torsion disc is threaded onto the surface of the fixed tube. A movable disc is rotatably connected to the bottom of the torsion disc, and several push rods are hinged to the bottom of the movable disc. A movable sleeve is fixed to the other end of the push rod, and the interior of the movable sleeve is rotatably connected to the surface of the fixed rod.

[0009] Preferably, the outer side of the fixed tube is provided with several sliding grooves, and the inner side of the movable disc is slidably connected to the inside of the sliding grooves.

[0010] Preferably, a movable rod is fixedly connected to the outer side of the guide plate, and the surface of the movable rod is movably connected to the inside of the fixed tube.

[0011] Preferably, the inner side of the guide plate is movably connected with a number of balls, and the balls are arranged at equal intervals.

[0012] Preferably, a plurality of tapered rods are fixed to the bottom of the base plate.

[0013] Preferably, the base plate has several fixing pins running through its interior.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] Before drilling, the present invention, with the setting of a base plate, a fixed plate, a fixed tube, and several guide plates, can guide and limit the drill rod, enabling it to move vertically downwards and preventing the drill rod from tilting during drilling. At the same time, through the movable connection between the surface of the movable rod and the inside of the fixed tube, the guide plate can be moved. In this way, the position of the guide plate can be adjusted according to the size of the drill rod, so as to facilitate the guidance of drill rods of different sizes and thus improve applicability.

[0021] 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.

[0022] Please see Figure 1-4As shown, a rotary drilling pile verticality control device includes a base plate 1. Several tapered rods 16 are fixed to the bottom of the base plate 1 to increase the friction between the base plate 1 and the ground, thereby improving the stability when fixing the base plate 1. Several fixing pins 17 are installed through the interior of the base plate 1, so that after the base plate 1 contacts the ground, the fixing pins 17 can be embedded to stably fix the base plate 1 to the ground. Several fixing plates 2 are fixed to the top of the base plate 1, and fixing pipes 3 are fixed to the other end of the fixing plates 2. Several movable rods 4 are movably connected to the surface of the fixing pipes 3. One end of each movable rod 4 is fixedly connected to a guide plate 5, and the inner side of the guide plate 5 is movable. Several ball bearings 14 are connected and arranged at equal intervals to reduce the friction between the guide plate 5 and the drill rod, facilitating the up-and-down movement of the drill rod. A connecting rod 7 is hinged to the other end of the movable rod 4. A support rod 6 is hinged to the outside of the fixed plate 2. A fixed rod 8 is fixedly connected to one side of the support rod 6. The other end of the support rod 6 is hinged to the other end of the connecting rod 7. A torsion plate 9 is threadedly connected to the surface of the fixed tube 3. A movable plate 10 is rotatably connected to the bottom of the torsion plate 9. Several push rods 11 are hinged to the bottom of the movable plate 10. A movable sleeve 12 is fixed to the other end of the push rod 11. The inside of the movable sleeve 12 is rotatably connected to the surface of the fixed rod 8.

[0023] The outer side of the fixed tube 3 is provided with several sliding grooves 15, and the inner side of the movable plate 10 is slidably connected to the inside of the sliding grooves 15. This can provide auxiliary limiting for the movable plate 10, making it easier for it to move up and down.

[0024] A movable rod 13 is fixedly connected to the outside of the guide plate 5. The surface of the movable rod 13 is movably connected to the inside of the fixed tube 3, so as to provide auxiliary support for the guide plate 5 and maintain its stability when moving.

[0025] It is worth noting that the technical features proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.

[0026] Working principle: In use, the base plate 1 can be fixed at the drilling position by the fixing pin 17. Then, as the drill rod enters the inner side of the fixed tube 3, multiple workers can simultaneously apply force to rotate the torsion plate 9, which will drive the torsion plate 9 and the movable plate 10 to move upward. As the movable plate 10 moves, it will apply force to the push rod 11, so that the support rod 6 can be deflected at an angle and push the connecting rod 7 and the movable rod 4, thereby driving the guide plate 5 to move towards the surface of the drill rod, so that the inner side of the guide plate 5 contacts the surface of the drill rod. In this way, drill rods of different sizes can be guided to maintain the verticality of the drill rod when drilling.
