Description

Technical Field

[0001] The utility model belongs to the technical field of sampling equipment, and in particular relates to a sampling device for construction engineering detection. Background Art

[0002] Currently, before construction, in order to ensure that building materials meet the standards of construction, samples will be taken for inspection or testing before use. In order to ensure the accuracy of the inspection, in addition to sampling the surface of the material, the deeper part of the material will also be extracted. Currently, most common methods use shovels or hollow straight cylinders for extraction. The former is prone to collapse due to the gravity of the material itself during sampling, resulting in difficulty in sampling deep materials or excessive mixing of surface materials. The latter is prone to excessive resistance when inserting into the material during sampling, resulting in inconvenience caused by excessive resistance during sampling. Utility Model Content

[0003] The purpose of the utility model is to provide a sampling device for construction engineering detection, which is used to solve the problems mentioned in the background technology.

[0004] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] The sampling mechanism comprises a main shaft, a spiral lifting blade, a turning handle and an end cover. The main shaft rotation seal is arranged in the sampling barrel. The spiral lifting blade is arranged on the main shaft and fits the inner wall of the sampling barrel. The turning handle is arranged at the other end of the main shaft. The sampling barrel as a whole is in a "wine bottle-shaped" structure. The diameter of the sampling barrel close to the turning handle is smaller than that of the other side. The length of the spiral lifting blade corresponds to the end with a larger diameter. The non-turning handle end of the sampling barrel is open and has a "needle-shaped" structure. The end cover is arranged at the opening of the sampling barrel.

[0007] The side of the sampling tube is also provided with a discharge mechanism.

[0008] The discharge mechanism includes a side cover, a traction assembly and a lock. A discharge window matching the spiral lifting blade is opened on the side of the sampling barrel.

One end of the two cables is connected to the handle, and the other ends of the two cables are connected and matched with the two locks respectively.

[0010] The lock includes a slide, a spring, a locking tongue and a locking platform.

[0023] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-6 As shown, a sampling device for construction engineering inspection includes a sampling tube 1, in which a sampling mechanism is provided:

[0025] The sampling mechanism includes a main shaft 2, a spiral lifting blade 21, a turning handle 22 and an end cover. The main shaft 2 is rotatably sealed and arranged in the sampling barrel 1. The spiral lifting blade 21 is arranged on the main shaft 2 and fits the inner wall of the sampling barrel 1. The turning handle 22 is arranged at the other end of the main shaft 2. The sampling barrel 1 is in a "wine bottle-shaped" structure as a whole. The diameter of the sampling barrel 1 on the side close to the turning handle 22 is smaller than that on the other side. The length of the spiral lifting blade 21 corresponds to the end with a larger diameter. The end of the sampling barrel 1 not at the turning handle 22 is open and in a "needle-shaped" structure. The end cover is arranged at the opening of the sampling barrel 1.

[0026] The side of the sampling tube 1 is also provided with a discharge mechanism.

[0027] During construction, in order to ensure that the materials used in the construction meet the requirements, the materials used in the construction will be sampled and tested. When using the device for sampling, hold the sampling tube 1, and then insert the sampling tube 1 into the construction material. At this time, hold the sampling tube 1 with one hand and turn the handle 22 with the other hand. At this time, the handle 22 drives the main shaft 2 to rotate, and the spiral lifting blades 21 on the main shaft 2 cooperate with the relatively closed environment of the sampling tube 1 to lift the building materials on the lower side until a suitable amount is extracted. In order to facilitate the observation of the sampled amount, a transparent observation window can be provided on the side of the sampling tube 1 to make it easier for the user to observe the sampled amount. After the sampling is completed, the sampling tube 1 is tilted upward and immediately to prevent some materials such as stones from slipping out, and finally the opening of the sampling tube 1 is closed by the end cover. That is, according to the specific environment during sampling, the closed opening sampling tube 1 can be directly used as a storage device to store materials, or after placing the sampling tube 1 in a suitable storage container such as a barrel, bag, etc., the end cover can be opened to utilize the gravity of the material itself to fall and cooperate with the reverse drive spiral lifting blade 21 to discharge the material. Compared with the traditional shovel sampling, it can extract enough materials at one time and avoid the inconvenience of sampling some materials that are easy to spill. At the same time, it can also be used directly as a storage object. Compared with some cylindrical insertion samplers, this device can overcome the insertion resistance more easily through the spiral lifting blade 21. When sampling, the spiral lifting blade 21 can be rotated while continuously inserted into the deep of the material, thereby reducing the difficulty of sampling and making it easier to take samples from the inner side of the material.

[0028] The discharge mechanism includes a side cover 3, a traction assembly and a lock. A discharge window 31 matching the spiral lifting blade 21 is opened on the side of the sampling barrel 1. The side cover 3 is hinged on the side of the sampling barrel 1 and corresponds to the discharge window 31. The traction assembly is arranged on the side of the side cover 3 close to the handle 22, and the lock is arranged between the side cover 3 and the sampling barrel 1.

[0029] The traction assembly includes a handle 4 and a cable 41. The handle 4 is slidably arranged on the side of the side cover 3 close to the turning handle 22. There are two cables 41 and they are both slidably embedded in the side cover 3. There are two locks and they are respectively arranged on the left and right sides of the side cover 3. One end of the two cables 41 is connected to the handle 4, and the other ends of the two cables 41 are respectively connected and matched with the two locks.

[0030] The locker includes a slide 5, a spring 51, a locking tongue 52 and a locking platform 53. The locking platform 53 is fixed to the sampling tube 1 and corresponds to the other end of the side cover 3 away from the pull plate. The side cover 3 is provided with a wire hole connecting the cable 41 and a step cavity 54 of the external space. The slide 5 is slidably arranged in the step cavity 54. The locking tongue 52 is connected to one end of the slide 5 and extends out of the step cavity 54. The locking platform 53 is provided with a limiting hole 55 matching the locking tongue 52. The inclined surface of the locking tongue 52 is located on the side away from the discharge window 31. The cable 41 is connected to the other end of the slide 5. The spring 51 is sleeved on the cable 41 and is located in the step cavity 54.

[0031] When the material sample needs to be released after sampling is completed, in order to release the material more quickly and conveniently, and also to facilitate the cleaning of the sampling tube 1 at a later time, the pull rope 41 can be pulled by pulling the pull handle 4 in the traction assembly. The pull rope 41 is pulled to drive the slide plate 5 to slide away from the locking platform 53. At this time, the locking tongue 52 gradually disengages from the connection with the locking platform 53, that is, the limit of the side cover 3 is released. At this time, the side cover 3 is flipped downward by the gravity of the material in the sampling tube 1 to open the discharge window 31. The material falls and pours downward along the side cover 3. In this way, the material can be discharged more quickly, and the directly opened discharge window 31 can directly clean the sampling tube 1, so as to avoid the residue of the previous sampling affecting the next sampling.

[0032] When the discharge is completed, it is only necessary to push the side cover 3 to flip toward the discharge window 31 side of the sampling tube 1. When the locking tongue 52 passes through the locking platform 53 to the corresponding limiting hole 55, the spring 51 will cause the locking tongue 52 to reconnect to the locking platform 53, thereby limiting and locking the side cover 3 again for the next sampling. This operation is convenient and quick, and is more convenient for sampling needs.

[0033] A handle 6 is also provided at one end of the sampling tube 1 away from the discharge window 31 ; this makes it easier to lift and hold the sampling tube 1 .

[0034] The maximum opening angle of the side cover 3 is 20°-45°. The side cover 3 is a semicircular structure as a whole and the circumferential angle is greater than the circumferential angle of the discharge window 31. Limiting the opening angle of the side cover 3 can prevent the side cover 3 from opening too large, which may cause the material to fall too fast and produce excessive impact force. The circumferential angle of the side cover 3 is greater than the discharge window 31, which can reduce the material falling out and improve the guiding effect on the material.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
