Description

Technical Field

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

[0002] Concrete slump mainly refers to the performance and pumpability of concrete. Conventional concrete slump detection devices mostly extract part of the concrete and pour it into a slump barrel, then lift it up manually and use tools to measure the slump of the concrete. The concrete is filled in three times. After each filling, the workers have to knock on the barrel wall to remove the air in the concrete pile. However, not only do the workers need to consume a lot of physical strength to perform multiple knocks, but the work efficiency is also low.

[0003] For example, a concrete slump detection device is disclosed in Chinese patent announcement No. CN219302461U. When in use, the bottom edge of the stacking bucket is fitted with two positioning edges, and then the knocking mechanism is driven to rotate to the top of the stacking bucket by the flipping mechanism. Then, the latch is pulled out to make the sliding block slide onto the supporting block. Then, concrete is added to the stacking bucket three times. After each addition of concrete, the stacking bucket is knocked by the knocking mechanism, and the rotating rod is driven to rotate by the electric motor, and the sprocket and the chain are driven to rotate by the rotating rod, so that the four rotating rods rotate at the same time. , the compression spring and the knocking ball are driven to rotate by the rotating rod, and the knocking ball is used to knock the stacking barrel, causing the stacking barrel to vibrate. The vibration of the stacking barrel drives the concrete inside it to vibrate, thereby expelling the air inside the concrete and the gaps inside the concrete pile. When the concrete is piled up, the knocking mechanism is removed, and then the stacking barrel is pulled out. The highest height of the concrete pile is measured by the height measuring mechanism. Then, the concrete pile is placed for a period of time and then collapses under the action of gravity. Then, the height of the concrete pile is measured again by the height measuring mechanism. The difference between the two heights is the slump.

[0004] However, the concrete slump detection device in the above application may cause the concrete to tilt due to factors such as hand shaking when the stacking barrel is manually pulled out, thereby affecting the accuracy of the detection. Therefore, it has certain limitations.

[0005] For this reason, we urgently need to provide a kind of concrete slump detection device. Utility Model Content

[0006] The purpose of the utility model is to provide a concrete slump detection device to solve the problem that when the concrete slump detection device proposed in the above background technology is manually pulled up, factors such as hand shaking may cause the concrete to tilt, thereby affecting the accuracy of the detection.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete slump detection device, comprising a base plate and a slump cylinder, the slump cylinder is placed in the center of the base plate, a lifting device and a detection device are arranged on the upper surface of the base plate, and fixing devices are arranged on the front and rear sides of the upper surface of the base plate respectively.

[0008] The lifting device includes a column, a lifting motor, a transmission member, and a connecting rod. The column is fixedly connected to the left side of the upper surface of the base plate, the lifting motor is installed on the top of the column, the transmission member is connected to the output end of the lifting motor, the connecting rod is fixedly connected to one side of the transmission member, and the other end of the connecting rod is connected to the slumping cylinder.

[0009] A further improvement is that a limiting groove is provided on the right outer surface of the column, the transmission member is installed inside the limiting groove, and the connecting rod is slidably connected to the inner wall of the limiting groove. When the concrete pouring is completed, the lifting motor is started to drive the screw in the transmission member to rotate, thereby driving the threaded sleeve and the connecting rod on one side thereof to move upward along the screw and the limiting groove, thereby driving the collapse cylinder to move upward in a straight line, thereby avoiding the situation where manual pulling of the cylinder causes the concrete to tilt.

[0010] A further improvement is that the detection device includes a knocking unit and a detection unit.

[0011] The knocking unit includes a rotating motor, a rotating shaft, a mounting block, a spring, and a knocking ball. The rotating motor is mounted on the upper surface of the base plate, the rotating shaft is connected to the output end of the rotating motor, the mounting block is fixedly connected to the top of the rotating shaft, the spring is fixedly connected to the front end of the mounting block, and the knocking ball is fixedly connected to the front end of the spring. After concrete is poured into the interior of the slump cylinder, the rotating motor is started to drive the rotating shaft to rotate, thereby driving the spring on one side of the mounting block at the top of the rotating shaft and the knocking ball at the outer end thereof to rotate and hit the slump cylinder, thereby driving the vibration of the slump cylinder to drive the concrete inside it to vibrate, thereby expelling the air inside the concrete to make it more compact.

[0012] A further improvement is that the detection unit includes a detection ruler, a sliding sleeve, and a pointer. The detection ruler is installed on the right side of the upper surface of the base plate, the sliding sleeve is slidably connected to the detection ruler, and the pointer is fixedly connected to the left side of the sliding sleeve. When the slump cylinder is pulled out, the height of the concrete pile is first detected by the pointer. After the concrete pile has been standing for a period of time, the height of the concrete pile is detected again by the pointer, and the difference between the two detections is the slump of the concrete pile.

[0013] A further improvement is that the fixing device includes a slide groove, a clamping block, a limiting rod, and a tension spring, the slide groove is opened at the front end of the upper surface of the base plate, the clamping block is slidably connected to the inside of the slide groove, the limiting rod is fixedly connected to the front inner wall of the slide groove, and the tension spring is installed inside the slide groove and is arranged around the outside of the limiting rod.

[0014] A further improvement is that the front and rear sides of the outer surface of the collapse cylinder are respectively provided with clamping holes identical to the clamping blocks, and the interior of the clamping block is penetrated by a through hole with the same diameter as the limiting rod. The collapse cylinder is fixed on the base plate by means of the clamping block cooperating with the clamping hole to prevent the collapse cylinder from being knocked up when the knocking unit knocks on the collapse cylinder, thereby affecting the stacking of the concrete pile. After the stacking is completed, the clamping block is pulled backward to move backward inside the slide groove, thereby squeezing the tension spring to lift the collapse cylinder.

[0015] A further improvement is that universal wheels are fixedly connected to the four corners of the lower surface of the base plate, and a trolley handle is fixedly connected to the left side of the base plate. By pushing the trolley handle, the device can be quickly moved under the drive of the universal wheels, which is more convenient to use.

[0018] 2. The concrete slump detection device, when the concrete pouring is completed, starts the lifting motor to drive the screw in the transmission part to rotate, thereby driving the threaded sleeve and the connecting rod on one side to move upward along the screw and the limit slide groove, thereby driving the slump cylinder to move upward in a straight line, avoiding the situation where manual pulling of the cylinder causes the concrete to tilt.
