DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] As Figure 1As shown in the figure, a device for detecting the verticality of a pile foundation pile body includes an n-shaped bracket 1. Auxiliary plates 2 are fixedly connected to both the left and right sides of the n-shaped bracket 1. A detection component 7 is connected inside the n-shaped bracket 1. The detection component 7 can detect the balance of the foundation pile. Grooves 3 are provided on the inner walls of the left and right sides of the n-shaped bracket 1. A moving plate 4 is movably connected between the two grooves 3. A hydraulic pump 1 is fixedly installed at the rear end of the inner wall of the top side of the n-shaped bracket 1, and the output end of the hydraulic pump 1 is fixedly connected to the moving plate 4. Two hydraulic pumps 2 5 are fixedly connected to the bottom of the moving plate 4, and the output ends of the two hydraulic pumps 2 5 are both fixedly connected to columnar piles 6.

[0027] As can be seen from the above, the columnar pile 6 is used to correct the inclination of the device in this solution, not the verticality of the foundation pile.

[0028] As Figure 2 、 3 As shown in the figure, the detection component 7 includes two brackets 71. The two brackets 71 are located directly above the moving plate 4. A horizontal bubble 72 is fixedly connected above the two brackets 71.

[0029] When the bubble tube is placed on an uneven surface, due to the imbalance of the surface tension and pressure of the liquid, the bubble will move towards the higher place to find a new balance point. The displacement size of the bubble can reflect the inclination degree of the level.

[0030] Furthermore, two detection plates 1 73 are fixedly connected to the directly below of the moving plate 4. Push rods 74 are slidably connected to the inner bottom ends of the two auxiliary plates 2. The two push rods 74 respectively penetrate the left and right sides of the two auxiliary plates 2 and the left and right side walls of the n-shaped bracket 1 and are fixedly connected to two detection plates 2 75. Two linkage components 76 are connected between the two detection plates 2 75 and the two detection plates 1 73.

[0031] As Figure 4 、 5 As shown in the figure, the linkage component 76 includes a rack 1 761 and a rack 2 769. Slide grooves 7693 are provided at the left end of the top of the push rod 74 and the lower left end of the left side of the detection plate 1 73. The rack 1 761 and the rack 2 769 are respectively slidably connected in the two slide grooves 7693.

[0032] Furthermore, fixed grooves 7694 are fixedly provided at the left end inside the push rod 74 and the lower end inside the detection plate 1 73. A spring plate 1 764 and a spring plate 2 7692 are respectively installed in the two fixed grooves 7694. The left end of the spring plate 1 764 and the bottom end of the spring plate 2 7692 are respectively fixedly connected to the two fixed grooves 7694.

[0033] Further, the right end of the first spring plate 764 and the top end of the second spring plate 7692 are respectively slidably connected to the fixed groove 7694. The top end of the first spring plate 764 and the left end of the second spring plate 7692 respectively penetrate through the two sliding grooves 7693 and are fixedly connected to the first rack 761 and the second rack 769.

[0034] Further, the first rack 761 and the second rack 769 are respectively meshed with a first gear 762 and a second gear 7691. The rear ends of the first gear 762 and the second gear 7691 are respectively fixedly connected to a first rotating shaft 763 and a second rotating shaft 766. The rear ends of the first rotating shaft 763 and the second rotating shaft 766 are both rotatably connected to the n-shaped bracket 1. The rear ends of the first rotating shaft 763 and the second rotating shaft 766 are respectively fixedly connected to a first pulley 765 and a second pulley 767. The outer surfaces of the second pulley 767 and the first pulley 765 are drivingly connected by the same belt 768.

[0035] As can be seen from the above, when the first hydraulic pump is started, it further drives the two first detection plates 73, the second spring plate 7692, the second rack 769, the moving plate 4, the two second hydraulic pumps 5 and the two column piles 6 to move downward. Since the groove 3 is movably connected to the moving plate 4, the two first detection plates 73 can contact the side wall of the precast pile. At the same time, during the downward movement of the second spring plate 7692, it drives the second gear 7691 to rotate, further drives the second pulley 767 to rotate, and drives the first pulley 765 to rotate through the belt 768, further drives the first rotating shaft 763 to rotate, so that the first gear 762 drives the first rack 761 to approach the foundation pile. If the two first detection plates 73 have already contacted the foundation pile, but the two second detection plates 75 have not contacted, it can continue to move downward and compress the second spring plate 7692, so that the two second detection plates 75 contact the two sides of the foundation pile, and the device is clamped on the side wall of the precast pile for fixation. Then, by observing the inclination of the bubble in the horizontal bubble 72, the verticality of the foundation pile can be determined.

[0036] As above, the device is clamped on the side wall of the precast pile. During the piling process, the operator can determine whether the precast pile is vertical by observing the horizontal bubble in time, and then drive the pile downward step by step to maintain the verticality of the precast pile. During the process of the precast pile entering the soil, the device needs to be moved upward so that the device can always stay above the ground during the process of the precast pile entering the soil, which is convenient for the operator to observe.

[0037] In addition, according to the drilling methods of cast-in-place piles, there are rotary drilling rigs, cast-in-place pile drilling rigs, etc. Generally, this solution is not applicable to rotary drilling rigs, as rotary drilling rigs already have a verticality detection mechanism. This solution can be applicable to cast-in-place pile drilling rigs.

[0038] Clamp the device on the rack perpendicular to the drilling of the cast-in-place pile drilling rig, which is convenient for the operator to observe whether the rack is vertical in time, thereby controlling the quality of the hole formation.

[0039] The present technology is applicable to the following two construction processes:

[0040] 1. The precast pile is a pile body prefabricated in a factory or a specific site and is driven into the soil by means of hammering, static pressure or vibration at the construction site. This device can be applicable to the process of transporting the precast pile to the construction site and hammering it.

[0041] 2. The cast-in-place pile refers to a pile formed by using a drilling machine to drill a pile hole and pouring concrete in the hole or first suspending a steel reinforcement cage in the hole. This device can be applicable to the process of controlling the verticality in the drilling stage and is not applicable to the pouring stage.

[0042] The working principle of the present utility model is as follows: During the driving of the precast pile, through the detection component 7 and the linkage component 76, the device can be firmly clamped on the rack perpendicular to the drill hole of the cast-in-place pile drilling rig. Then, by observing the inclination of the bubble in the horizontal bubble 72 and the degree of fit between the two detection plates II 75 and the pile foundation, the verticality of the foundation pile can be determined. When the device tilts, the corresponding hydraulic pump II 5 is started, which can drive the column pile 6 to correct the device in time.

[0043] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
