Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a device for detecting the setting time of concrete. Background Technique

[0002] Concrete is a commonly used building material. Concrete has the advantage of quick setting. Generally, the setting time of concrete is divided into initial setting and final setting. The time from adding water until the cement paste begins to lose plasticity and the fluidity decreases is called the initial setting time. The time from adding water until the cement paste completely loses plasticity and begins to have a certain structural strength is called the final setting time. By detecting the setting time of concrete, the construction period can be planned well, which is beneficial to the orderly progress of construction.

[0003] In the prior art, the Chinese utility model patent with the patent publication number of CN207081636U discloses a device for detecting the setting time of concrete, including a base, a concrete bucket and a detection part. A column for supporting the detection part is vertically extended on the base. The detection part is provided with a support rod. The top end of the support rod is hinged with a handle. The detection part is provided with a bracket above the concrete bucket. The bracket is fixedly connected with the support rod. A test needle for testing the pressure value of the concrete is arranged below the bracket. A main shaft hinged with the handle is arranged above the bracket. The main shaft drives the test needle to slide up and down. The detection part is provided with a pressure display on one side of the base. A groove for the support rod to fit and insert is recessed on the column. A threaded hole is opened at the upper end of the column. The column is provided with a fastening stud threadedly connected with the threaded hole, which has the beneficial effect of improving the operation convenience. At the same time, with the help of a limiting spring and a flexible part, the adjustment accuracy is improved.

DETAILED DESCRIPTION

[0018] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] See also Figures 1-4 The concrete setting time detection device of the utility model comprises a base 1, a bottom end of a movable plate 3 is rotatably connected with a rotating shaft 4, the rotating shaft 4 is fixedly connected to the top of the base 1, a connecting plate 5 is fixedly connected to the upper position of the left end of the movable plate 3, an arc-shaped elastic clamping plate 6 is fixedly connected to the connecting plate 5, a concrete bucket 2 is clamped and placed on the base 1 by the arc-shaped elastic clamping plate 6, a fixed plate 7 is fixedly connected to the top of the base 1, a guide plate 8 is slidably provided on the fixed plate 7, a pull ring 9 is fixedly connected to the right end of the guide plate 8, a top plate 10 is fixedly connected to the left end of the guide plate 8, and two sets of symmetrical fixed connections are provided between the right end of the top plate 10 and the left end of the fixed plate 7. Spring 11, two groups of limit pins 12 are symmetrically fixed on the left end of the top plate 10, and two groups of limit holes 13 are symmetrically provided on the lower side of the right end of the movable plate 3 to cooperate with the limit pins 12. The top plate 10 is pressed against the right end of the movable plate 3 under the action of the spring 11, and the two groups of limit pins 12 are respectively inserted into the two groups of limit holes 13; when in use, the guide plate 8 is pulled to the right by the pull ring 9 to slide, so that the guide plate 8 drives the top plate 10 to move to the right, and then the spring 11 is further compressed, and the top plate 10 drives the limit pin 12 to move to the right, so that the limit pin 12 is disengaged from the limit hole 13, and then the movable plate 3 can be rotated, so that the movable plate 3 is driven by the connecting plate 5 The arc-shaped elastic clamping plate 6 is rotated to the side, and then the concrete bucket 2 is placed into the arc-shaped elastic clamping plate 6 from above. When the concrete bucket 2 is placed, the arc-shaped elastic clamping plate 6 will be supported outward, so that the concrete bucket 2 is clamped by the arc-shaped elastic clamping plate 6, and then the movable plate 3 is rotated back to its original position to align the limiting hole 13 with the limiting pin 12. Then, after loosening the pull ring 9, the limiting pin 12 is inserted into the limiting hole 13 under the action of the spring 11, and the top plate 10 is against the movable plate 3. The movable plate 3 is limited by the limiting pin 12 to prevent rotation, and then the concrete bucket 2 is pushed downward to make the concrete bucket 2 move downward. The bottom end of the concrete bucket 2 is against the top of the base 1. At this time, the concrete bucket 2 is below the detection part, and then the subsequent detection operation can be carried out. After the detection, if you want to remove the concrete bucket 2, use the same method to rotate the movable plate 3, so that the arc-shaped elastic clamping plate 6 drives the concrete bucket 2 to turn to the side, and then the concrete bucket 2 can be removed from the arc-shaped elastic clamping plate 6. The arc-shaped elastic clamping plate 6 is driven to rotate by the movable plate 3. This can prevent the concrete bucket 2 from interfering with the detection part when it is taken and placed, so that the concrete bucket can be placed more stably, avoiding movement or tipping during the detection process, preventing the detection from being affected, and improving practicality.

[0021] A handle 14 is fixedly provided at the top of the movable plate 3 . By providing the handle 14 , the movable plate 3 can be rotated by holding the handle 14 , making the movable plate 3 more convenient to rotate.

[0022] An anti-slip rubber pad 15 is fixedly connected to the inner wall of the arc-shaped elastic splint 6; by providing the anti-slip rubber pad 15, the friction on the inner wall of the arc-shaped elastic splint 6 can be increased, making the clamping of the concrete bucket 2 by the arc-shaped elastic splint 6 tighter and more secure, and preventing slipping.

[0023] An anti-slip grip sleeve 16 is fixedly sleeved on the handle 14; by providing the anti-slip grip sleeve 16, it can prevent the hand from slipping when holding the handle 14 to rotate the movable plate 3.

[0024] A buffer pad 17 is fixedly connected to the left end of the top plate 10, and the buffer pad 17 is sleeved on the two limit pins 12; by providing the buffer pad 17, when the pull ring 9 is released and the spring 11 rebounds, it can prevent the top plate 10 from directly hitting the movable plate 3, playing a buffering role.

[0025] For the concrete setting time detection device of the present utility model, its working principle is as follows: during use, the guide plate 8 is slid to the right by pulling the pull ring 9, so that the guide plate 8 drives the top plate 10 to move to the right, further compressing the spring 11. The top plate 10 drives the limit pin 12 to move to the right, causing the limit pin 12 to disengage from the limit hole 13. Then the movable plate 3 can be rotated, so that the movable plate 3 drives the arc-shaped elastic splint 6 to rotate through the connecting plate 5, turning the arc-shaped elastic splint 6 to the side. Then the concrete bucket 2 is placed into the arc-shaped elastic splint 6 from above. When the concrete bucket 2 is placed, it will push the arc-shaped elastic splint 6 outwards, thereby clamping the concrete bucket 2 through the arc-shaped elastic splint 6. Then the movable plate 3 is rotated back to its original position, aligning the limit hole 13 with the limit pin 12. Then, after releasing the pull ring 9, the limit pin 12 is inserted into the limit hole 13 under the action of the spring 11, and the top plate 10 abuts against the movable plate 3, limiting the movable plate 3 through the limit pin 12 to prevent rotation. Then the concrete bucket 2 is pushed downwards so that the bottom end of the concrete bucket 2 abuts against the top end of the base 1. At this time, the concrete bucket 2 is located below the detection part, and then subsequent detection operations can be carried out. After the detection, if the concrete bucket 2 needs to be removed, the movable plate 3 is rotated in the same way, so that the arc-shaped elastic splint 6 drives the concrete bucket 2 to turn to one side, and then the concrete bucket 2 can be removed from the arc-shaped elastic splint 6. By driving the arc-shaped elastic splint 6 to rotate through the movable plate 3, it can prevent interference with the detection part when the concrete bucket 2 is taken and placed.
