Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete slump detection auxiliary device. Background Art

[0002] Slump refers to the workability of concrete. Workability refers to whether the concrete is easy to construct and whether it is uniformly dense. It is a very comprehensive property that includes fluidity, cohesion and water retention. Therefore, it is often necessary to test the slump of concrete.

[0003] The traditional detection method uses a slump cone as an aid. The existing detection method is to pour concrete into the slump cone multiple times, then use a tamping hammer to tamp it evenly from the outside to the inside along the wall of the barrel, and then smooth it out. Finally, the barrel is pulled up, and the concrete collapses due to its own weight. The height of the highest point of the concrete after collapse is subtracted from the height of the barrel, which is called the slump.

[0004] For example, the Chinese utility model patent with application number 201822237961.0 provides a slump detection device, which is provided with a lifting device connected to the slump bucket on the base. The slump bucket can be driven by the lifting device to move in the vertical direction, which effectively avoids the impact and vibration caused by the shaking during the manual operation and ensures the accuracy of the slump measurement value.

[0005] However, the existing concrete slump detection device is not convenient for quickly cleaning the slump cone after detection, so that concrete is easily attached to the inner wall of the slump cone, making subsequent manual cleaning time-consuming and labor-intensive. Therefore, in view of this, a concrete slump detection auxiliary device is proposed to solve the above technical problems. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model proposes a concrete slump detection auxiliary device to solve the technical problem that the existing concrete slump detection device proposed in the above background technology is not convenient for quickly cleaning the slump cylinder after detection, so that concrete is easily attached to the inner wall of the slump cylinder, making subsequent manual cleaning time-consuming and labor-intensive.

[0007] In order to achieve the above object, the utility model provides the following technical solution, a concrete slump detection auxiliary device, comprising:

[0008] A vehicle frame, wherein a mounting frame is provided on the vehicle frame;

[0009] A mounting ring, which is escalably arranged on the mounting frame, and a slump tube is arranged inside the mounting ring;

[0010] A lifting mechanism, arranged on the mounting frame, to drive the mounting ring to rise and fall;

[0011] A turnover mechanism, which is arranged on the mounting frame and connected to the mounting ring, so as to drive the mounting ring and the collapse cylinder to turn when the mounting ring is raised or lowered; and

[0012] A cleaning mechanism is arranged on the frame to wash the inner wall of the overturned collapse cylinder.

[0013] In a preferred embodiment, a slider is slidably provided on the mounting frame so as to be liftable, and a mounting shaft is provided on the mounting ring. The mounting shaft is rotatably provided along its axis and penetrates the slider.

[0014] In a preferred embodiment, the lifting mechanism includes:

[0015] A screw rod is rotatably disposed on the mounting frame along its axis and is threadedly connected to the slider; and

[0016] The first motor is arranged on the mounting frame, and the output shaft of the first motor is connected with the lead screw.

[0017] In a preferred embodiment, the flipping mechanism includes a connecting block, which is fixedly arranged at the end of the mounting shaft, and a driving shaft is arranged on the connecting block, and the axis of the driving shaft does not coincide with the axis of the mounting shaft. An arc track is opened on the mounting frame, and straight tracks are arranged at both ends of the arc track, and the driving shaft is slidably clamped in one group of the straight tracks.

[0018] In a preferred embodiment, the cleaning mechanism comprises:

[0019] A cleaning brush rotatably disposed on the mounting frame;

[0020] A second motor is disposed on the mounting frame, and an output shaft thereof is connected to the cleaning brush; and

[0021] A spray head is arranged on the mounting frame, and a water supply device connected with the spray head is arranged on the vehicle frame.

[0022] In a preferred embodiment, a waste water tank is provided on the frame, and a rotatable receiving plate is provided in the waste water tank.

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] When the device is in use, the installation ring can be driven to descend to the lowest position through the lifting mechanism, so that the bottom surface of the collapse cylinder contacts the ground, and concrete is added into the collapse cylinder, and then the collapse cylinder is controlled to rise through the lifting mechanism to detect the slump of concrete. Since the collapse cylinder is trumpet-shaped, the diameter of its upper opening is smaller than the diameter of its bottom opening. It is inconvenient to clean its inner wall when the bottom opening is downward. After the detection is completed, the collapse cylinder can be controlled to continue to rise. During the rising process, the collapse cylinder is flipped under the action of the flip mechanism, so that the bottom opening of the collapse cylinder faces upward, and the inner wall of the collapse cylinder can be quickly cleaned through the cleaning mechanism, which effectively prevents the concrete from solidifying and adhering to the inner wall of the collapse cylinder, reducing the labor intensity of the staff.

[0034] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0035] Example:

[0036] like Figure 1 , 3 As shown, the utility model provides a concrete slump detection auxiliary device, including a frame 101, a mounting frame 201 is arranged on the frame 101, a mounting ring 301 is arranged on the mounting frame 201 so as to be liftable, a slump cone 401 is arranged in the mounting ring 301, a slider 303 is arranged on the mounting frame 201 so as to be liftable and slidable, a mounting shaft 302 is arranged on the mounting ring 301, and the mounting shaft 302 is rotatably arranged in the slider 303 along its axis.

[0037] When the device is in use, the collapse cone 401 can be used for detection. During the detection process, the mounting ring 301 and the collapse cone 401 can be driven to rise by controlling the slider 303 to rise, and the mounting ring 301 and the collapse cone 401 can be driven to flip by controlling the rotation of the mounting shaft 302.

[0038] like Figure 3 As shown, in this embodiment, a lifting mechanism for driving the mounting ring 301 to rise and fall is provided on the mounting frame 201, and the lifting mechanism includes a screw rod 204 rotatable along its axis and provided on the mounting frame 201, the screw rod 204 is screwed to the slider 303, and a first motor 205 is provided on the mounting frame 201, and the output shaft of the first motor 205 is connected to the screw rod 204.

[0039] During use, the first motor 205 can be controlled to start driving the screw rod 204 to rotate. During the rotation process, the screw rod 204 can drive the slider 303 to rise and fall through the threaded connection with the slider 303, thereby making the mounting ring 301 and the collapse cone 401 rise and fall. During the detection process, there is no need to manually lift the collapse cone 401, saving the physical strength of the staff.

[0040] like Figure 1 , 3 As shown, in this embodiment, a flipping mechanism connected to the mounting ring 301 is provided on the mounting frame 201, and the mounting ring 301 and the collapse cone 401 are driven to flip when the mounting ring 301 is raised or lowered by the flipping mechanism. The flipping mechanism includes a connecting block 304, and the connecting block 304 is fixedly arranged at the end of the mounting shaft 302. A driving shaft 305 is arranged on the connecting block 304, and the axis of the driving shaft 305 does not coincide with the axis of the mounting shaft 302. An arc track 202 is opened on the mounting frame 201, and straight tracks 203 are arranged at both ends of the arc track 202. The driving shaft 305 is slidably clamped in one group of straight tracks 203.

[0041] As the slider 303 rises and falls to drive the mounting ring 301 and the collapse cone 401 to rise, the drive shaft 305 first slides in the straight track 203. When the drive shaft 305 slides from the straight track 203 into the curved track 202, since the axes of the drive shaft 305 and the mounting shaft 302 do not coincide, the drive shaft 305 can be deflected under the guidance of the curved track 202, thereby driving the mounting shaft 302 to rotate through the connecting block 304, thereby driving the collapse cone 401 to flip over. After flipping, the bottom opening of the collapse cone 401 faces upward, making it more convenient to clean its inner wall.

[0042] like Figure 1 , 2 As shown, in this embodiment, a cleaning mechanism is provided on the frame 101, and the inner wall of the overturned collapse cone 401 is washed by the cleaning mechanism. The cleaning mechanism includes a cleaning brush 106 rotatably provided on the mounting frame 201, a second motor 105 is provided on the mounting frame 201, the output shaft of the second motor 105 is connected to the cleaning brush 106, a nozzle 104 is provided on the mounting frame 201, and a water supply device 103 connected to the nozzle 104 is provided on the frame 101.

[0043] After the collapse cone 401 is flipped over, the slider 303 is continuously controlled to rise, so as to drive the flipped collapse cone 401 to rise, until the collapse cone 401 covers the cleaning brush 106, and the bristles of the cleaning brush 106 can fit with the inner wall of the flipped collapse cone 401, and then the second motor 105 is started to drive the cleaning brush 106 to rotate, so as to clean the inner wall of the collapse cone 401, and at the same time, water can be supplied to the nozzle 104 through the water supply device 103, and the water supply device 103 can be a water tank with a water pump, or an external water source for water supply, and the nozzle 104 sprays water onto the inner wall of the collapse cone 401 to improve the cleaning effect, and can clean the inner wall of the collapse cone 401 in time without manual cleaning, and also prevents the concrete from adhering to the inner wall of the collapse cone 401 after solidification.

[0044] like Figure 2 As shown, in this embodiment, a wastewater tank 102 is provided on the frame 101, and a rotatable receiving plate 107 is provided in the wastewater tank 102. During the cleaning process, the receiving plate 107 can also be flipped to an inclined state so that the end of the receiving plate 107 is located below the collapse cylinder 401, and the sewage generated during the cleaning process is guided into the wastewater tank 102, which is convenient for recycling the sewage and reducing pollution to the environment.

[0045] Specific usage and beneficial effects of the utility model:

[0046] When the device is in use, the first motor 205 can be used to control the rotation of the screw rod 204, so that the mounting ring 301 can be driven to descend to the lowest point through the cooperation between the screw rod 204 and the slider 303, so that the bottom surface of the slump cone 401 contacts the ground, and concrete is added into the slump cone 401, and then the screw rod 204 is controlled to flip to drive the slump cone 401 to rise, so as to perform concrete slump detection. Since the collapse cone 401 is trumpet-shaped, the diameter of its upper opening is smaller than the diameter of its bottom opening. It is inconvenient to clean its inner wall when the bottom opening is facing downward. After the detection is completed, the collapse cone 401 can be controlled to continue to rise. During the rising process, the collapse cone 401 drives the driving shaft 305 to move, and the driving shaft 305 and the arc track 202 cooperate to drive the mounting shaft 302 to rotate, so that the mounting ring 301 and the collapse cone 401 are flipped, so that the bottom opening of the collapse cone 401 faces upward, and the cleaning brush 106 can be driven by the second motor 105 to rotate to brush the collapse cone 401, and the collapse cone 401 can be rinsed through the nozzle 104, so that the inner wall of the collapse cone 401 is quickly cleaned, and the concrete is effectively prevented from solidifying and adhering to the inner wall of the collapse cone 401, thereby reducing the labor intensity of the staff.
