[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-4 As shown, this utility model provides a hole forming quality inspection device, including: a depth measuring rod 1, with a first threaded hole 2 at the top end, a first stud 3 at the bottom end, and a length scale 4 on the outer wall; an extension rod 5, with a second threaded hole 6 at the top end that mates with the first stud 3, and a second stud 7 at the bottom; and a diameter measuring disc assembly 8, including a ring 81, a connector 82 fixedly disposed at the center of the ring 81 and coinciding with the axis of the ring 81, and a third threaded hole 83 opened at the top end of the connector 82 for screwing into the second stud 7.

[0024] Before use, the depth rod 1, the extension rod 5 and the diameter gauge assembly 8 are in a split state for carrying and storage, when in use, the first stud 3 is screwed into the second threaded hole 6, the second stud 7 is screwed into the third threaded hole 83, thereby combining the three into a whole, then the whole is vertically inserted into the pile hole to be checked, the diameter of the circular ring 81 is set to be slightly smaller than the designed diameter of the pile hole, if the pile hole has good hole forming quality, the diameters at each height of the pile hole are basically the same, then the diameter gauge assembly 8 can be smoothly inserted to the bottom of the pile hole, at this time, the reading of the length scale 4 corresponding to the top surface of the pile hole is read, the depth of the pile hole can be obtained, and compared with the designed depth of the pile hole, thereby judging the hole forming quality, if the diameter gauge assembly 8 cannot be inserted to the bottom due to the blockage of the inner wall of the pile hole, it can be known that the diameter error of the pile hole is large, and the hole forming quality is judged as unqualified. The hole forming quality of the pile hole can be checked through simple insertion operation, which greatly improves the checking efficiency.

[0025] It is worth noting that when the length scale 4 is made, the initial length is not zero, but the height after the extension rod 5 and the diameter gauge assembly 8 are combined.

[0026] In an embodiment, the diameter gauge assembly 8 further comprises a sleeve 84 arranged above the connecting head 82 for sleeving the outer wall of the extension rod 5, and a plurality of inclined struts 85 fixedly arranged at one end on the circular ring 81 and fixedly arranged at the other end on the outer wall of the sleeve 84, the plurality of inclined struts 85 are uniformly arranged around the axis of the circular ring 81, and the sleeve 84 coincides with the axis of the circular ring 81.

[0027] In this way, when the diameter gauge assembly 8 rubs against the inner wall of the pile hole during insertion, the sleeve 84 abuts against the outer wall of the extension rod 5, the extension rod 5 transmits the supporting force to the circular ring 81 through the sleeve 84 and the inclined struts 85, preventing the circular ring 81 from tilting due to rubbing, and improving the structural stability of the diameter gauge assembly 8 as a whole.

[0028] In an embodiment, a leveling support assembly 9 is further included, which comprises a positioning sleeve 91 movably sleeved on the extension rod 5, a locking member 92 arranged on the positioning sleeve 91 for locking the position of the positioning sleeve 91 on the extension rod 5, an extension mounting plate 93 fixedly arranged at the bottom of the positioning sleeve 91, and three telescopic support feet 94 uniformly and hingedly arranged on the bottom surface of the extension mounting plate 93.

[0029] In this way, when the pile hole to be inspected is deep, it is difficult to ensure that the depth probe 1 and the extension rod 5 are always kept in the vertical state during the insertion process by manpower, so that the qualification of the pile hole diameter cannot be accurately inspected. In this case, before the insertion of the diameter measuring disc assembly 8, the position of the positioning sleeve 91 on the extension rod 5 is adjusted by the locking member 92, and the telescopic supporting feet 94 are in contact with the ground. By adjusting the length or inclination angle of each telescopic supporting foot 94, the positioning sleeve 91 is kept in the horizontal state, and then the extension rod 5 is kept in the vertical state, and the insertion operation is performed to ensure the accuracy of the inspection result of the hole quality.

[0030] In an embodiment, the locking member 92 comprises a protrusion 921 fixedly arranged on the outer wall of the positioning sleeve 91, an abutting screw 922 threadedly connected and arranged in the positioning sleeve 91 and the protrusion 921, and a hand wheel 923 fixedly arranged on the end of the abutting screw 922 extending out of the protrusion 921.

[0031] In this way, the abutting screw 922 can be screwed into or out of the protrusion 921 by rotating the hand wheel 923. When the abutting screw 922 is screwed into the protrusion 921 and abuts against the outer wall of the extension rod 5, the position of the positioning sleeve 91 on the extension rod 5 is locked under the action of friction. When the abutting screw 922 is screwed out of the protrusion 921, the abutting screw 922 is separated from the outer wall of the extension rod 5, and the positioning sleeve 91 and the extension rod 5 can easily slide relative to each other.

[0032] In an embodiment, the leveling support assembly 9 further comprises a bubble level 95 fixedly arranged on the top surface of the outer extension mounting plate 93.

[0033] In this way, whether the positioning sleeve 91 is in the horizontal state can be determined by the bubble level 95.

[0034] In an embodiment, a handle 10 detachably arranged on the top end of the depth probe 1 is further included, and the bottom of the handle 10 is fixedly provided with a third threaded stud 11 matched with the first threaded hole 2.

[0035] In this way, the third threaded stud 11 is threadedly connected with the first threaded hole 2, and the installation of the handle 10 is completed, and the insertion and extraction operation is more convenient by holding the handle 10.

[0036] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.

[0037] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture, and if the specific posture changes, the directional indications will also change accordingly.
