Description

Technical Field

[0001] The utility model relates to the technical field of crack measurement, in particular to a crack measuring instrument for geological exploration. Background Technique

[0002] A ground crack is a geological phenomenon in which the surface rock and soil body crack under the action of natural or human factors and form a crack with a certain length and width on the ground. When this phenomenon occurs in an area with human activities, it can become a geological disaster. Therefore, mastering its change trend is an important basis for engineering technicians to take corresponding preventive measures in a timely manner.

[0003] A crack measuring instrument suitable for cracks of different widths disclosed in the Chinese patent with the publication number of CN220304437U includes a measuring instrument main body, a support rod and a moving rod, and the lower end of the measuring instrument main body is connected with the support rod. This crack measuring instrument suitable for cracks of different widths is provided with a second connecting plate. When the distance between the measuring rods needs to be adjusted, the second connecting plate can be pulled to drive the second support plate to move, so that it can be separated from the measuring instrument main body, and then the measuring rods can be moved to make them close to the inner wall of the crack, so as to facilitate the measurement of the crack and make it convenient to use.

[0004] In view of the above related technologies, there are some deficiencies in this device. In the actual use process, the fixing structure and the measuring structure of the device are both restricted to specific positions of the measuring instrument main body. Such a design makes the device occupy a large volume whether it is in use or not. This volume limitation not only makes the device inconvenient to carry, but also makes it particularly troublesome in the daily storage and placement process. Therefore, it is necessary to provide a crack measuring instrument for geological exploration to solve the above technical problems. Content of the Utility Model

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-4 , an embodiment provided by the present utility model:

[0028] A crack measuring instrument for geological exploration, comprising:

[0029] A horizontal rail 1, on which symmetrically distributed first adjustment blocks 3 and second adjustment blocks 4 are slidably installed. A measuring telescopic rod 6 is fixedly installed at the bottom of the second adjustment block 4. An adjustment telescopic rod 15 is fixedly installed at the bottom of the first adjustment block 3. A pressing plate 13 is fixedly installed at the telescopic end of the adjustment telescopic rod 15, and a inserting rod 14 is fixedly installed at the bottom of the pressing plate 13;

[0030] The adjustment telescopic rod 15 is threadedly connected to a second butterfly bolt 11 through a threaded hole opened on the lower side of its outer wall. Both the first adjustment block 3 and the second adjustment block 4 are threadedly connected to a first butterfly bolt 10 through threaded holes opened on their fronts. A scale line 7 is arranged on the upper side of the front of the horizontal rail 1.

[0031] Vertical rails 2 are fixedly installed on both sides of the top of the horizontal rail 1, and the vertical rails 2 are adapted to both the first adjustment block 3 and the second adjustment block 4.

[0032] In one embodiment, a strap 9 is fixedly installed at the top of one vertical rail 2, and a hanging ring 8 is fixedly installed at the top of the other vertical rail 2. A safety buckle 12 is fixedly installed at one end of the strap 9, and the safety buckle 12 is hooked to the hanging ring 8.

[0033] In one preferred embodiment, a finger rod 5 is fixedly installed on the front of the second adjustment block 4, which is convenient for staff to observe corresponding data.

[0034] In one embodiment, the material of the strap 9 is polyester. Polyester is a synthetic fiber material with wear resistance, high strength and anti-tensile properties, and has good durability and stability. Its use makes the strap 9 more firm when bearing heavy objects, and is not easy to deform or wear. In addition, polyester also has good water resistance and drying speed, and can keep the performance of the strap 9 stable in various environments.

[0035] In one preferred embodiment, the materials of both the horizontal rail 1 and the vertical rail 2 are aluminum alloy. This material selection makes the horizontal rail 1 and the vertical rail 2 not only have high strength and durability, but also maintain a light weight, which helps to improve the overall portability and convenience of use of the device. The use of aluminum alloy can also effectively resist corrosion and extend the service life of the device.

[0036] The working principle of the present utility model is as follows: For the parts not involved in this device, they are the same as the prior art or can be implemented using the prior art. When measuring a crack, due to the slidability of the first adjusting block 3 on the cross rail 1, slide the two first adjusting blocks 3 to both sides of the cross rail 1. Then, tighten the first wing bolt 10 to fix the first adjusting block 3 on the cross rail 1. Next, insert the two insertion rods 14 into the ground on both sides of the crack to fix the device at the measurement position. After the device is fixed, if it is found not to be in a horizontal state, adjust the telescopic property of the telescopic rod 15 to adjust the length of the telescopic rod 15, and at the same time, cooperate with the second wing bolt 11 to lock the adjusted telescopic rod 15 to ensure that after the device is fixed, it can be easily adjusted to a horizontal state, facilitating the subsequent crack measurement operation. Subsequently, according to the sliding of the second adjusting block 4 on the cross rail 1, drive the measuring telescopic rod 6 to move, so that the measuring telescopic rod 6 extends into the crack, and make the two measuring telescopic rods 6 close to the side of the crack. Then, tighten the first wing bolt 10 on the second adjusting block 4 to lock the position of the second adjusting block 4, ensuring the stability of the position of the measuring telescopic rod 6 during the measurement process. According to the position indicated by the pointer rod 5 on the scale line 7, the width data of the crack can be quickly obtained. When the device is no longer in use, directly loosen the first wing bolt 10, and then slide and disassemble the first adjusting block 3 and the second adjusting block 4 from both ends of the cross rail 1, slide and insert them onto the vertical rails 2 on both sides of the top of the cross rail 1, and lock their positions with the first wing bolt 10, so that when the device is not in use, the measuring telescopic rod 6 and the telescopic rod 15 are disassembled from the cross rail 1 and installed on the vertical rails 2. In this way, these rods will be arranged perpendicular to the cross rail 1 during operation, and when not in use, they can be placed parallel to the cross rail 1 and close together. This greatly reduces the overall volume of the device, making it more compact during storage and transportation. In this way, users can carry and store the device more conveniently, thereby improving the convenience of use.

[0037] After disassembling, reassembling and storing the device, the safety buckle 12 at one end of the strap 9 can be hooked on the hanging ring 8, forming a cross strap on the top of the device. The staff can directly carry the device by hand through the strap 9, or carry the device on the shoulder with the strap 9, further improving the convenience of people's use and making the carrying easier and more flexible.

[0038] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit 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.
