Description

Technical Field

[0001] The utility model relates to the technical field of hole forming detection of expanded anchor rods, in particular to a hole forming detector. Background Art

[0002] The expanded anchor hole detector is a special device used to detect and evaluate the expanded anchor hole (or hole expansion). Expanded anchor is a common anchoring technology in geotechnical engineering. It provides higher anchoring capacity through the length and diameter of the anchor (expanded part). The hole detector is a detection tool used to ensure that the hole expansion process meets the design and construction requirements.

[0003] A Chinese utility model with authorization announcement number CN219455036U discloses an expanded anchor hole detector. When in use, the device can buffer the collision position when the detection probe collides or falls by setting an arc-shaped collision plate in conjunction with an airbag. However, in actual use, when the detection probe falls to the bottom of the hole, the buffer component set cannot withstand all the forces. The generated force will cause the probe to rebound and then fall to the ground. The detection probe in this device only has a buffer component installed at the bottom. When it falls, the outer wall of the detection probe may be damaged. Therefore, it is necessary to redesign the hole detector to address the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a hole forming detector.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The hole forming detector comprises a detection probe, the outer wall of which is square, and mounting grooves are provided at the four corners of the detection probe, and airbags are installed in the mounting grooves. Two groups of slide grooves are provided on the lower end surface of the detection probe, and the positions are symmetrical to each other. Pistons are slidably connected in the two groups of slide grooves, and one-way valves are installed in the slide grooves. The two groups of slide grooves are connected to the two adjacent groups of airbags through connecting pipes respectively.

[0007] Preferably, a sliding rod is slidably connected in the sliding groove, one end of the sliding rod is fixedly connected to the piston, and the other end of the sliding rod is fixedly connected to a buffer plate.

[0008] Preferably, the outer wall of the buffer plate is fixedly connected to two groups of anti-arc plate bodies, the two groups of anti-arc plate bodies are symmetrically positioned, the buffer plate and the inner walls of the two groups of anti-arc plate bodies are both arc-shaped, and the curvature of the buffer plate and the inner wall of the anti-arc plate body are opposite.

[0009] Preferably, the outer walls of the two groups of sliding rods are sleeved with springs, one end of the spring is fixedly connected to the outer wall of the buffer plate, and the other end of the spring is fixedly connected to the lower end surface of the detection probe.

[0010] Preferably, a connecting rope is installed at the upper end of the detection probe, and the buffer plate and the anti-arc plate body are both made of rubber material.

[0011] Preferably, the two groups of sliding groove notches are fixedly connected to limit rings, and the sliding rod is slidably connected to the limit rings.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model is provided with airbags, pistons and other devices. When the detection probe falls, the force generated drives the slide rod to drive the piston to slide upward in the slide groove. During sliding, the gas inside the slide groove can be quickly injected into the airbags through the connecting pipe. The airbags are quickly inflated to protect the detection probe from the four corners, provide shock absorption effect from the sides and other parts, and reduce the possibility of damage to the outer wall of the detection probe.

[0014] 2. The utility model provides a buffer plate, an anti-arc plate and other devices. When the detection probe falls, the buffer plate that makes the first contact will buffer first, and then the force will be transmitted to the anti-arc plate body. The two work together to more effectively disperse and absorb the impact force of the fall. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 The hole forming detector comprises a detection probe 1, the outer wall of the detection probe 1 is square, the four corners of the detection probe 1 are provided with mounting grooves, the mounting grooves are provided with airbags 4, the lower end surface of the detection probe 1 is provided with two groups of slide grooves 8, and the positions are symmetrical to each other, the two groups of slide grooves 8 are slidably connected with pistons 9, the slide grooves 8 are provided with one-way valves 10, and the two groups of slide grooves 8 are respectively connected with the two adjacent groups of airbags 4 through connecting pipes;

[0022] refer to Figure 2 and Figure 3 When the detection probe 1 falls, the force generated drives the slide rod 6 to drive the piston 9 to slide upward in the slide groove 8. During sliding, the gas inside the slide groove 8 can be quickly injected into the airbag 4 through the connecting pipe. The airbag 4 is quickly inflated to protect the detection probe 1 from the four corners, provide shock absorption effect from the side and other parts, and improve the overall protection performance, so as to avoid the detection probe 1 rebounding and causing damage to the outer wall; and when it needs to be explained, a one-way valve 10 is arranged in the slide groove 8 to prevent the piston 9 from being affected by the spring 7 and the air injected into the airbag 4 is withdrawn.

[0023] A slide rod 6 is slidably connected in the slide groove 8, one end of the slide rod 6 is fixedly connected to the piston 9, and the other end of the slide rod 6 is fixedly connected to the buffer plate 3. Two groups of anti-arc plate bodies 5 are fixedly connected to the outer wall of the buffer plate 3. The two groups of anti-arc plate bodies 5 are symmetrically located. The inner walls of the buffer plate 3 and the two groups of anti-arc plate bodies 5 are both arc-shaped, and the curvature of the inner walls of the buffer plate 3 and the anti-arc plate bodies 5 are opposite;

[0024] Reference Figure 2 and Figure 4 , the outer walls of the two sets of slide bars 6 are sleeved with springs 7, one end of the spring 7 is fixedly connected to the outer wall of the buffer plate 3, and the other end of the spring 7 is fixedly connected to the lower end surface of the detection probe 1;

[0025] The energy absorbed by the spring 7 is transferred to the piston 9 in the slide groove 8 through the slide rod 6. As the slide rod 6 moves, the gas is filled into the airbag 4 through the connecting pipe to further absorb the remaining impact energy.

[0026] A connecting rope 2 is installed at the upper end of the detection probe 1. The buffer plate 3 and the anti-arc plate body 5 are both made of rubber material. The two sets of slide grooves 8 are fixedly connected at the notches with limit rings 11. The slide rod 6 is slidably connected to the limit ring 11. The setting of the limit ring 11 can prevent the piston 9 from escaping from the slide groove 8 during daily use.

[0027] In this utility model, reference Figure 1, the buffer plate 3 and the anti-arc plate body 5 are combined to form a multi-level buffer structure. When the detection probe 1 falls, the buffer plate 3 that contacts for the first time will buffer first, and then the force will be transmitted to the anti-arc plate body 5. The two work together to more effectively disperse and absorb the impact force of the fall. The spring 7 that is set begins to compress at the moment the detection probe 1 falls, first absorbing a part of the impact energy, dispersing and slowing down the initial impact force. The energy absorbed by the spring 7 is transmitted to the piston 9 in the slide groove 8 through the slide rod 6. With the movement of the slide rod 6, the gas is filled into the airbag 4 through the connecting pipe to further absorb the remaining impact energy. When the detection probe 1 rebounds for the second time due to the force, the air in the airbag 4 at the four corners will maintain a certain pressure level, so that when the detection probe 1 rebounds for the second time, a soft cushion is quickly formed to alleviate the impact of contacting the ground again, thereby reducing the possibility of external damage to the detection probe 1.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
