Description

Technical Field

[0001] The utility model relates to the technical field of cement solidification detection, and particularly relates to a device for detecting the solidification time of cement. Background Art

[0002] At present, premixed cement is used as a construction material in many fields. During construction, the control of the cement solidification time directly affects the construction period and progress. Therefore, the detection of the cement solidification time has become an important issue.

[0003] The cement is in a static state in the cement box, so the thickness distribution of the cement is uneven. Since the solidification time of cement with different thicknesses is different, the accuracy of the detection result is low. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a device for detecting the solidification time of cement to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A device for detecting the solidification time of cement includes a support mechanism. A shaking mechanism is fixedly connected to the support mechanism, and a detection mechanism is provided on the support mechanism. The detection mechanism is located above the shaking mechanism.

[0007] The shaking mechanism includes a driving motor and a moving plate. The output end of the driving motor is fixedly connected with a turntable. A T-shaped connecting rod is fixedly connected to the upper surface of the turntable. A chute is formed on the surface of the moving plate.

[0008] A further improvement of the technical solution of the utility model is that the T-shaped connecting rod is movably connected inside the chute. A connecting plate is fixedly connected to the moving plate. Limiting rings are sleeved on both the left and right ends of the connecting plate. A cement box is fixedly connected to the upper surface of the connecting plate. When the T-shaped rod rotates, the connecting plate is driven to move through the chute, and then the cement box is driven to shake left and right.

[0009] A further improvement of the technical solution of the utility model is that the support mechanism includes a base. The driving motor is fixedly connected to the lower surface of the base. A fixing groove is formed inside the base. The turntable is rotatably connected inside the fixing groove. The limiting ring is fixedly connected inside the fixing groove. The connecting plate is movably connected inside the fixing groove. The base and the fixing groove respectively fix the positions of the driving motor and the turntable, thereby improving the stability of the device.

[0010] A further improvement of the technical solution of the present utility model lies in that: a support frame is fixedly connected to the upper surface of the base, and a timer is arranged on the base. When detecting the setting time of cement, the timer records the time.

[0011] A further improvement of the technical solution of the present utility model lies in that: the detection mechanism includes an electric telescopic rod. One end of the electric telescopic rod is fixedly connected to the support frame, and the telescopic end of the electric telescopic rod is fixedly connected to a double-layer limiting rod. A pressure sensor is fixedly connected to the top of the double-layer limiting rod. When the electric telescopic rod operates, it can drive the double-layer limiting rod and the pressure device to move.

[0012] A further improvement of the technical solution of the present utility model lies in that: an oil storage cotton is arranged inside the sandwich layer of the double-layer limiting rod, and a limiting groove is opened on the inner wall of the double-layer limiting rod. The oil storage cotton contacts the rotating beads through the limiting groove, thereby avoiding damage to the oil storage cotton.

[0013] A further improvement of the technical solution of the present utility model lies in that: a detector is movably connected inside the double-layer limiting rod. Rotating beads are symmetrically arranged on the left and right sides of the detector, and a spring is fixedly connected to the top of the detector. After the detection is completed, the pressure received by the spring disappears, and the detector is driven by its own elastic force to return to its original position, thus facilitating the next use.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0015] 1. The present utility model provides a device for detecting the setting time of cement. When the driving motor operates, it drives the turntable to rotate. The T-shaped connecting rod rotates around the center of the turntable. When the T-shaped connecting rod moves, it drives the moving plate to move left and right through the sliding groove. The connecting plate moves synchronously with the moving plate, thereby driving the cement box to shake left and right. Its two ends move within the limiting ring to ensure the stability when the cement box shakes, so that the cement in the cement box is more evenly distributed, and further improves the detection accuracy.

[0016] 2. The present utility model provides a device for detecting the setting time of cement. When the electric telescopic rod is started, it drives the double-layer limiting rod to move downward, so that the detector contacts the cement and presses downward. During the downward movement of the double-layer limiting rod, the rotating beads are attached to the oil storage cotton, so that the surface of the rotating beads is attached with lubricating oil, and further makes the movement of the detector smoother. The pressure received by the detector is transmitted into the pressure sensor through the spring. When the pressure received by the pressure sensor reaches a fixed value, the electric telescopic rod is turned off, and the time of the timer is recorded, thereby improving the detection convenience.

[0025] Specifically, the driving motor 11 operates to drive the turntable 12 to rotate, the T-shaped connecting rod 13 rotates around the center of the turntable 12, when the T-shaped connecting rod 13 moves, it drives the moving plate 14 to move left and right through the chute 15, and the connecting plate 16 moves synchronously with the moving plate 14, thereby driving the cement box 18 to shake left and right, and its two ends move inside the limit rings 17 to ensure the stability of the cement box 18 during shaking, so that the cement in the cement box 18 is more evenly distributed, thereby improving the accuracy of detection.

[0026] Embodiment 2

[0027] As Figures 1 - 4As shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the support mechanism 2 includes a base 21, the drive motor 11 is fixedly connected to the lower surface of the base 21, a fixing groove 22 is formed inside the base 21, the turntable 12 is rotatably connected inside the fixing groove 22, a limiting ring 17 is fixedly connected inside the fixing groove 22, a connecting plate 16 is movably connected inside the fixing groove 22, a support frame 23 is fixedly connected to the upper surface of the base 21, and a timer 24 is arranged on the base 21;

[0028] Specifically, the base 21 and the support frame 23 respectively support and connect the shaking mechanism 1 and the detection mechanism 3, avoiding shaking during detection, thereby ensuring the accuracy of detection. The fixing groove 22 restricts the position of the turntable 12, thereby avoiding the phenomenon of the turntable 12 falling off. The timer 24 cooperates with the pressure sensor 32 to record the cement setting time.

[0029] Embodiment 3

[0030] As Figures 1 - 4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the detection mechanism 3 includes an electric telescopic rod 31, one end of the electric telescopic rod 31 is fixedly connected to the support frame 23, the telescopic end of the electric telescopic rod 31 is fixedly connected with a double-layer limiting rod 33, the top of the double-layer limiting rod 33 is fixedly connected with a pressure sensor 32, an oil storage cotton 34 is arranged inside the sandwich of the double-layer limiting rod 33, a limiting groove 35 is formed on the inner wall of the double-layer limiting rod 33, a detector 36 is movably connected inside the double-layer limiting rod 33, rotating beads 37 are symmetrically arranged on the left and right of the detector 36, and a spring 38 is fixedly connected to the top of the detector 36;

The T-shaped connecting rod 13 rotates around the center of the turntable 12. When the T-shaped connecting rod 13 moves, it drives the moving plate 14 to move left and right through the sliding groove 15. The connecting plate 16 moves synchronously with the moving plate 14, thereby driving the cement box 18 to shake left and right, so that the cement in the cement box 18 is more evenly distributed. After the cement has solidified for a period of time, the electric telescopic rod 31 is started to drive the double-layer limiting rod 33 to move downward, so that the detector 36 contacts the cement and presses downward. The detector 36 then moves upward. During the upward movement, the rotating bead 37 abuts against the oil storage cotton 34, so that the surface of the rotating bead 37 is attached with lubricating oil, further making the movement of the detector 36 smoother. The pressure received by the detector 36 is transmitted into the pressure sensor 32 through the spring 38. When the pressure received by the pressure sensor 32 reaches a fixed value, the electric telescopic rod 31 is turned off, and the time of the timer 24 is recorded.
