Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering construction, and specifically relates to an all-directional mechanical measuring device for pile holes. Background Technique
[0002] In the pile foundation project, the measurement of the pile hole before pile formation is one of the key steps to ensure the project quality. The main purpose of pile hole measurement is to ensure that the diameter, depth and verticality of the pile hole meet the design requirements, so as to ensure the bearing capacity and stability of the pile foundation.
[0003] The detection of the hole formation quality mainly involves measuring the diameter, depth and verticality of the drilled hole to ensure that the drilled hole meets the design requirements. This is carried out by using professional measuring tools and techniques, including using a diameter gauge to measure the hole diameter, using a depth gauge to measure the hole depth, and detecting the verticality of the hole through an instrument.
[0004] In actual operation, more attention is often paid to the quality inspection after pile formation, while ignoring the quality control in the hole formation stage. This deviation in concept may lead to the problems in the hole formation stage being ignored. Compared with the detection technology after pile formation, the hole formation detection technology develops relatively slowly, which to a certain extent affects the accuracy and efficiency of pile hole measurement. The measuring instruments and equipment used by some units are aging and cannot meet the current standards and regulations requirements for pile foundation detection, resulting in inaccurate or unreliable measurement data. In addition, common hole formation detectors often easily fail, including broken wire ropes, irregular wire ropes and cable wires, malfunction of the upper and lower limit switches, malfunction of the numerical control winch for lifting and lowering, abnormal power supply of the main control box, communication failure, etc., and need to be regularly inspected and maintained.
[0005] Therefore, it is more important to select a pile foundation detection tool with a wider application range, simplicity and ease of use. Content of the Utility Model

[0010] Furthermore, the central shaft rod and the sleeve are movably connected.
[0011] Further, a contact rod pulling disc is arranged between the connecting rod, the bottom plate and the contact rod.
[0012] Further, the contact rod pulling disc is connected to the sleeve through a pull rod.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.
[0023] Embodiment 1:
[0024] As Figure 1As shown, a pile hole omnidirectional mechanical measuring device includes a sling 1, the sling 1 is connected to a central axis rod 3, a sleeve 4 is installed outside the central axis rod 3, the upper end of the sleeve 4 is connected to an operating rope 2, the lower end of the sleeve 4 is connected to a base plate 7, and the base plate 7 is connected to a contact rod 8 through a connecting rod 9.
[0025] Embodiment 2:
[0026] like Figure 1 As shown, a pile hole omnidirectional mechanical measuring device comprises a sling 1, wherein the sling 1 is connected with a central axis rod 3, a sleeve 4 is installed outside the central axis rod 3, an upper end of the sleeve 4 is connected with an operating rope 2, a lower end of the sleeve 4 is connected with a bottom plate 7, and the bottom plate 7 is connected with a touch rod 8 through a connecting rod 9. The connecting rod 9 and the touch rod 8 are provided in several groups, and the number of the connecting rod 9 and the touch rod 8 is consistent. The touch rod 8 is arc-shaped, and the central axis rod 3 is movably connected with the sleeve 4. The telescopic movement of the central axis rod 3 in the sleeve 4 can drive the pull rod 6 on the sleeve 4 to move, so that the touch rod pull plate 5 slides on the connecting rod 9, so that under the drive of the connecting rod 9, the touch rod 8 is in an expanded or retracted state up and down, thereby realizing the detection of different pile foundation apertures. The connecting rod 9 is provided with a touch rod pull plate 5 between the bottom plate 7 and the touch rod 8, and the touch rod pull plate 5 is connected to the sleeve 4 through the pull rod 6.
[0027] In the embodiment of the utility model, two connecting holes are arranged on both sides of the top of the sleeve 4 for fixing the operating rope 2, and a plurality of through holes are arranged on the touch rod pull plate 5, through which the connecting rod 9 is connected with the touch rod pull plate 5.
[0028] The working principle of the utility model is as follows: when it is necessary to detect the diameter of the pile hole at each depth position and parameters such as the hole depth, the device of the utility model is placed into the borehole through a winch via a sling 1 and sunk to the bottom of the borehole. The depth of the pile hole can be detected by the length of the sling; the operating rope 2 is loosened to allow the casing 4 to slide down along the central axis rod 3, thereby driving the feeler rod pull plate 5 to slide on the connecting rod 9 via the pull rod 6, so that the feeler rod 8 is in an unfolded state, and then the device is lifted by the sling 1, and the diameters at different depths are measured by the tightness of the operating rope 2 during the lifting process. Specifically, by querying the outer diameter data of the feeler rod 8 corresponding to the lowering distance of the known operating rope 2, the aperture at the position can be obtained, and by measuring the apertures at multiple positions, a specific aperture data table can be determined, so that a data model of the aperture can be made.
[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
