Description

Technical Field

[0001] The utility model relates to the technical field of cement mixing pile detection, in particular to a cement mixing pile strength detection device. Background Art

[0002] Cement mixing piles refer to an effective form of soft foundation treatment. It uses cement as the main agent of the curing agent. The cement is sprayed into the soil by a mixing pile machine and fully mixed, so that a series of physical and chemical reactions occur between the cement and the soil, which hardens the soft soil and improves the foundation strength. Cement mixing piles are divided into single-axis, double-axis and three-axis mixing piles according to the main construction methods used. It uses a special deep mixer to forcefully mix the soft soil and cement (curing agent), and uses a series of physical and chemical reactions between cement and soft soil to consolidate the soil, forming a cement soil pile with integrity, water stability and a certain strength. This process is mainly used for the treatment of soft soil foundations.

[0003] Cement mixing piles are a commonly used foundation treatment method. By mixing cement with soil and utilizing the solidification effect of cement, the bearing capacity and stability of the soil can be improved. However, the quality of cement mixing piles is affected by many factors, such as soil properties, cement content, construction technology, etc. Therefore, testing the strength of cement mixing piles is an important means to ensure their quality.

[0004] Three days after the pile is formed, a simple detection method of light dynamic probing is usually used to test the strength of the mixing pile. The simple detection method is to use a flat-head steel bar with a length of 2m and a diameter of 16mm to stand vertically on the top of the pile, and roughly judge the strength of the pile top by the situation of human pressure. If 10cm can be pressed in by manpower, it indicates that there may be problems with the construction quality. However, this method requires manpower to apply pressure, and the labor intensity is relatively high. At the same time, due to the large number of cement mixing piles, the labor intensity of the operators is greatly enhanced, and the operation is not convenient enough, time-consuming and labor-intensive, and the detection efficiency is low. Therefore, the utility model provides a new cement mixing pile strength detection device, which aims to solve the above problems. Utility Model Content

[0005] In view of the existing deficiencies, the utility model provides a cement mixing pile strength detection device, which solves the problems raised by the above background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A cement mixing pile strength detection device comprises a support plate, a vertical pole is vertically penetrated through the center of the support plate, positioning components are arranged at the four corners of the support plate, a weight is sleeved on the vertical pole, a baffle is fixed on the annular surface of the vertical pole, and the baffle is located on the lower side of the weight, and a driving mechanism is arranged inside the support plate.

[0008] Furthermore, the positioning assembly includes a hinge joint, a support rod, a ground plug and a positioning foot plate. Support rods are provided at the four corners of the support plate. The upper end of the support rod is rotatably connected to the support plate through a hinge joint. The lower end of the support plate is fixedly connected to the positioning foot plate. A ground plug is provided throughout the interior of the positioning mixer.

[0009] Furthermore, the driving mechanism includes an incomplete gear, a notch, a rotating shaft, a handle and a strip plate. The notch is opened on the right side inside the support plate. An incomplete gear is arranged inside the notch. The incomplete gear is rotatably connected to the support plate through the rotating shaft. A handle is installed at the front end of the rotating shaft. The left side of the incomplete gear is meshingly connected to a rack plate.

[0010] Furthermore, a slide groove is provided on the right side of the ring surface of the vertical pole, and the rack plate is clamped in the slide groove.

[0011] Furthermore, a limit slider is fixedly provided on the inner ring surface of the weight, the limit slider is inserted into the slide groove, and the upper end of the limit slider is fixedly connected to the lower end of the rack plate.

[0012] Furthermore, a sliding sleeve is embedded in the connection between the support plate and the vertical pole, and the right side of the sliding sleeve is an open structure, and the opening width is the same as the slot width.

[0013] Furthermore, the pole ring surface is provided with scale lines near the bottom surface.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model can support the device as a whole through the positioning assembly to ensure the stability of the device. The driving mechanism is convenient for driving the heavy hammer to rise and then fall freely under the action of gravity to hit the baffle to perform strength testing, which improves the convenience of the testing operation, reduces the labor intensity, and improves the testing efficiency.

[0016] 2. The utility model provides a stable support for the detection device through the coordinated action of the support rod, the positioning foot plate and the ground plug, ensuring that the device will not move or tilt due to external factors during the detection process. The design of the hinge joint allows the support rod to adjust the angle within a certain range, thereby adapting to different terrains and working environments, and improving the adaptability and flexibility of the device.

[0017] 3. A slide groove is opened on the right side of the pole ring surface, and the rack plate is stuck in the slide groove. The slide groove provides a clear movement trajectory for the rack plate. When the rack plate moves up and down under the drive of the incomplete gear, the slide groove ensures that the rack plate can move smoothly along the vertical direction of the pole to prevent it from deflecting or moving horizontally.

[0018] 4. A limit slider is fixed on the inner ring surface of the weight, which is inserted into the slide groove, and the upper end of the limit slider is fixedly connected to the lower end of the rack plate. This design uses the limit slider to limit the weight, ensuring the stability of the weight during the lifting process and the accuracy of the vertical movement, and preventing the weight from deflecting or rotating during the movement. The limit slider also realizes the linkage between the weight and the rack plate. When the rack plate moves up and down under the action of the driving mechanism, the limit slider will move accordingly, thereby driving the weight to rise and fall.

[0019] 5. There are scale lines on the ring surface of the vertical pole near the bottom surface. The scale lines provide an intuitive measurement reference for the inspectors. By observing the alignment between the surface of the mixing pile and the scale lines, the depth of the vertical pole penetrating into the mixing pile can be understood, thereby determining the strength of the mixing pile.

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example:

[0028] like Figures 1 to 5As shown, a cement mixing pile strength detection device comprises a support plate 1, a vertical pole 2 is vertically penetrated at the inner center of the support plate 1, positioning components 3 are arranged at the four corners of the support plate 1, a weight 4 is sleeved on the vertical pole 2, a baffle 6 is fixed on the annular surface of the vertical pole 2, and the baffle 6 is located at the lower side of the weight 4, and a driving mechanism 5 is arranged inside the support plate 1. This design solves the problems that the original simple detection method requires manpower to apply pressure, the manual labor intensity is relatively high, and at the same time, due to the large number of cement mixing piles, the labor intensity of the operator is greatly enhanced, and the operation is not convenient enough, time-consuming and labor-intensive, and the detection efficiency is low.

[0029] The positioning assembly 3 includes an articulated joint 31, a support rod 32, a ground plug 33 and a positioning foot plate 34. The support rods 32 are arranged at the four corners of the support plate 1. The upper end of the support rod 32 is rotatably connected to the support plate 1 through the articulated joint 31. The lower end of the support plate 1 is fixedly connected with the positioning foot plate 34. The ground plug 33 is arranged through the inside of the positioning mixer. The positioning assembly 3 is arranged to support the device as a whole to ensure the stability of the device. Through the coordinated action of the support rod 32, the positioning foot plate 34 and the ground plug 33, the positioning assembly 3 provides a stable support for the detection device to ensure that the device will not move or tilt due to external factors during the detection process. The design of the articulated joint 31 allows the support rod 32 to adjust its angle within a certain range, so as to adapt to different terrains and working environments, thereby improving the adaptability and flexibility of the device.

[0030] The driving mechanism 5 includes an incomplete gear 51, a notch 52, a rotating shaft 53, a handle 54 and a strip plate. The notch 52 is opened on the right side of the support plate 1. The notch 52 is provided with an incomplete gear 51. The incomplete gear 51 is rotatably connected to the support plate 1 through the rotating shaft 53. The front end of the rotating shaft 53 is equipped with a handle 54. The left side of the incomplete gear 51 is meshed and connected with a rack plate 55. The driving mechanism 5 is provided to facilitate driving the weight 4 to rise and then fall freely under the action of gravity to hit the baffle 6, so as to perform strength testing. When the operator turns the handle 54, the rotating shaft 53 drives the incomplete gear 51 to rotate, and the incomplete gear 51 meshes with the rack plate 55, converting its rotational motion into the vertical motion of the rack plate 55. When the incomplete gear 51 rotates to a position where it is disengaged from the rack plate 55, the rack plate 55 and the connected weight 4 fall freely under the action of gravity to hit the baffle 6. In this way, the driving mechanism 5 can accurately control the lifting and lowering of the heavy hammer 4, thereby realizing the strength detection of the cement mixing pile.

[0031] A slide groove 21 is provided on the right side of the ring surface of the vertical pole 2, and the rack plate 55 is stuck in the slide groove 21. The slide groove 21 provides a clear movement trajectory for the rack plate 55. When the rack plate 55 moves up and down under the drive of the incomplete gear 51, the slide groove 21 ensures that the rack plate 55 can move smoothly along the vertical direction of the vertical pole 2 to prevent it from deflecting or moving horizontally.

[0032] A limit slider 41 is fixedly arranged on the inner ring surface of the weight 4, and the limit slider 41 is inserted into the slide groove 21, and the upper end of the limit slider 41 is fixedly connected to the lower end of the rack plate 55. The design uses the limit slider 41 to limit the weight 4, ensure the stability of the weight 4 during the lifting process and the accuracy of the vertical movement, and prevent the weight 4 from deflecting or rotating during the movement. The limit slider 41 realizes the linkage between the weight 4 and the rack plate 55. When the rack plate 55 moves up and down under the action of the driving mechanism 5, the limit slider 41 will move accordingly, thereby driving the weight 4 to move up and down.

[0033] A sliding sleeve 11 is embedded in the connection between the support plate 1 and the vertical pole 2, and the right side of the sliding sleeve 11 is an open structure, and the width of the opening is the same as the width of the slot 52. The sliding sleeve 11 is embedded in the connection between the support plate 1 and the vertical pole 2, which can reduce the friction resistance of the vertical pole 2 during the up and down movement, making the lifting and lowering of the weight 4 smoother. At the same time, it plays a role in positioning the support plate 1, making it convenient to install the support plate 1.

[0034] The ring surface of the upright pole 2 is provided with scale lines 12 near the bottom surface. The scale lines 12 provide an intuitive measurement reference for the inspector. By observing the alignment between the surface of the mixing pile and the scale lines 12, the depth of the upright pole 2 penetrating into the mixing pile can be understood, thereby determining the strength of the mixing pile.

[0035] The working principle of the cement mixing pile strength detection device is as follows: in actual use, firstly, the vertical pole 2 is vertically erected on the pile top, and then the weight 4 is sleeved on the vertical pole 2, and the rack plate 55 is inserted into the slide groove 21 on the vertical pole 2. Then, the support plate 1 is sleeved on the vertical pole 2 through the sliding sleeve 11, and the incomplete gear 51 on it is meshed and connected with the rack plate 55. Then, the support rod 32 is unfolded and the positioning foot plate 34 is fixed through the ground plug 33, thereby realizing the fixation of the entire device. The operator turns the handle 54 and drives the incomplete gear 51 to rotate through the rotating shaft 53. The incomplete gear 51 meshes with the rack plate 55, converting the rotational motion into the vertical ascending motion of the rack plate 55. The rack plate 55 rises along the slide groove 21, and at the same time drives the weight 4 to rise through the limit slider 41. When the incomplete gear 51 rotates to a position where it is disengaged from the rack plate 55, the rack plate 55 and the weight 4 are no longer subject to the driving force and begin to fall freely under the action of gravity. The weight 4 falls and hits the baffle 6, and the impact force generated is transmitted to the upright pole 2, thereby driving the upright pole 2 to impact the cement mixing pile. The scale line 12 can be used to assist in observing and recording the depth of the upright pole 2 penetrating into the mixing pile when the weight 4 falls, so as to evaluate the strength of the cement mixing pile.

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
