Description

Technical Field

[0001] This utility model belongs to the field of slump testing technology, specifically relating to a cement concrete slump testing device. Background Technology

[0002] The main reason for testing the slump of cement concrete is to assess its workability (flowability and plasticity). Through testing, it can be verified whether the actual mixture is consistent with the mix design in the laboratory, so as to adjust the material ratio or the amount of admixtures in a timely manner, thereby ensuring that the concrete meets the project requirements during construction.

[0003] Chinese patent document CN219695125U discloses a concrete slump testing device. After cement is added to the slump cylinder, spread evenly, and fixed, the second drive motor is controlled by the control panel to drive the second threaded rod to rotate, so as to drive the slump cylinder to rise and detach from the cement. Then, the first drive motor works to drive the measuring plate, whose overall length has been adjusted, to a position that can overlap the top of the cement, so as to measure the slump height with the help of scale lines.

[0004] However, in the existing technology, although the detection device can greatly reduce the labor intensity of the detection work, the measurement work can only be carried out after the slump cylinder is raised to a certain height, so as to avoid the obstruction or dripping of mud, which would lead to inaccurate measurement. Therefore, a cement concrete slump detection device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a cement concrete slump testing device.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A cement concrete slump testing device includes a testing platform for the cement concrete to be tested to slump, a shifting component on the testing platform to improve the continuity of the testing work and ensure the accuracy of the test results, a measuring component on one side of the shifting component to measure the slump of the cement concrete, and a slump cylinder for holding the cement concrete to be tested below the measuring component.

[0008] The displacement assembly includes a loading component for separately installing the measuring component and the slump cylinder, an adjusting component for synchronously adjusting the height of the measuring component and the slump cylinder after operation, and a guide component for misaligning the measuring component and the slump cylinder when raised or lowered to a certain height.

[0009] The guide includes a positioning block fixedly installed below the testing table, a first upright fixedly connected above the positioning block, an intermediate frame fixedly connected above the first upright, and a second upright fixedly connected above the intermediate frame. Limit grooves are provided on the outer surfaces of both the first and second uprights.

[0010] Preferably, the adjusting member includes a locking bracket that is movably connected to the outer side of the first upright.

[0011] Preferably, the loading component includes a first carrier frame disposed on one side of the first upright, and a second carrier frame is movably connected to the outer side of the second upright.

[0012] Preferably, the adjusting component also includes a hydraulic cylinder fixedly installed on one side of the intermediate frame, with a transverse frame fixedly connected to the telescopic end of the hydraulic cylinder, and a transmission rod provided between the transverse frame, the locking frame, and the second carrier frame.

[0013] Preferably, both the first and second carriers have protrusions fixedly installed inside them.

[0014] Preferably, the first upright is slidably connected to the first carrier, the locking frame is rotatably connected to the first carrier, and the second upright is slidably connected to the second carrier.

[0015] Preferably, the locking frame, the second carrier frame, and the transverse frame are all rotatably connected to the transmission rod.

[0016] Preferably, the limiting groove of the first upright is composed of two vertical sections of different heights and a covering section, and the horizontal projections of the two vertical sections do not overlap.

[0017] Preferably, the limiting groove matches the protrusion.

[0018] The beneficial effects of this utility model are as follows: by setting the first and second uprights with different types of limiting grooves, when the loading component drives the measuring component and the slump cylinder to rise and fall due to the operation of the adjusting component, the slump cylinder can first rise and fall vertically to separate from the cement concrete, and then rotate horizontally while rising and falling, so that there is a certain degree of misalignment between it and the measuring component, thereby avoiding adverse effects on the measurement of the measuring component.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] like Figures 1-5As shown, a cement concrete slump testing device includes a testing platform 1 for testing cement concrete to slump, a shifting component 2 on the testing platform 1 to improve the continuity of testing work and ensure the accuracy of test results, a measuring component 3 on one side of the shifting component 2 to measure the slump of cement concrete, and a slump cylinder 4 for holding the cement concrete to be tested below the measuring component 3.

[0031] In this embodiment: the detection platform 1 serves as the installation base for this device, providing an installation position for the positioning block 201, a placement position for the collapse cylinder 4, and allowing the cement concrete contained in the collapse cylinder 4 to collapse onto it.

[0032] In this embodiment: the displacement component 2 includes a loading component that can respectively install the measuring component 3 and the collapse cylinder 4, an adjusting component that can synchronously adjust the height of the measuring component 3 and the collapse cylinder 4 after operation, and a guide component that can misalign the measuring component 3 and the collapse cylinder 4 when they are raised or lowered to a certain height;

[0033] The guide includes a positioning block 201 fixedly installed below the testing table 1. A first upright 202 is fixedly connected above the positioning block 201. An intermediate frame 203 is fixedly connected above the first upright 202. A second upright 204 is fixedly connected above the intermediate frame 203. Limiting grooves are provided on the outer surfaces of the first upright 202 and the second upright 204. The adjusting component includes a locking frame 205 movably connected to the outer side of the first upright 202. The loading component includes a first carrier 206 disposed on one side of the first upright 202. A second carrier 207 is movably connected to the outer side of the second upright 204. The adjusting component also includes a hydraulic cylinder 208 fixedly installed on one side of the intermediate frame 203. A transverse frame 209 is fixedly connected to the telescopic end of the hydraulic cylinder 208. A transmission rod 210 is provided between the transverse frame 209, the locking frame 205, and the second carrier 207.

[0034] Both the first carrier 206 and the second carrier 207 have protrusions fixedly installed inside. The first upright 202 is slidably connected to the first carrier 206. The locking frame 205 is rotatably connected to the first carrier 206. The second upright 204 is slidably connected to the second carrier 207. The locking frame 205, the second carrier 207, and the transverse frame 209 are all rotatably connected to the transmission rod 210. The limiting groove of the first upright 202 consists of two vertical sections of different heights and a covering section. The horizontal projections of the two vertical sections do not coincide. The limiting groove fits with the protrusion.

[0035] The positioning block 201, flush with the lower side of the testing table 1, provides support for the first upright 202 and its upper intermediate frame 203 and other components. The first upright 202, with its limiting groove, cooperates with the locking frame 205 to restrict the movable range of the first carrier 206, on which the collapse cylinder 4 can be installed, within the device. This allows the first carrier 206 to rotate horizontally at a certain angle when it is raised or lowered by external force to the section covered by the limiting groove of the first upright 202. The intermediate frame 203 provides an installation position for the hydraulic cylinder 208. The second upright 202, with its limiting groove... Rod 204 restricts the movable range of the second carrier 207, on which the measuring component 3 is installed, so that it can only be raised and lowered under the action of external force and cannot rotate. The power from the hydraulic cylinder 208 is changed in direction and stably transmitted to the first carrier 206 through the transverse frame 209, transmission rod 210 and locking frame 205, so that the first carrier 206 can drive the collapse cylinder 4 to rise and fall. Similarly, the power from the hydraulic cylinder 208 can be transmitted to the second carrier 207 through the transverse frame 209 and another transmission rod 210, so that the second carrier 207 can drive the measuring component 3 to rise and fall.

[0036] In this embodiment: the measuring component 3 includes an electric push rod 301 fixedly installed below the second carrier 207, a lifting plate 302 fixedly connected to the telescopic end of the electric push rod 301, a measuring rod 303 movably connected to the lifting plate 302, a loading plate 304 fixedly installed above the second carrier 207, a limit rod 305 fixedly connected below the loading plate 304, and a displacement sensor 306 fixedly installed on the loading plate 304;

[0037] The measuring rod 303 and the limiting rod 305 are slidably connected to the lifting plate 302. The lifting plate 302 is provided with a guide hole, and the loading plate 304 is provided with an installation hole. The upper end of the measuring rod 303 and the lower end of the limiting rod 305 are fixedly connected with anti-detachment plates. The guide hole and the installation hole correspond one-to-one. The measuring rod 303 is hollow.

[0038] The lifting plate 302 is driven to slide relative to the limiting rod 305 by the electric actuator 301, thereby changing the height of the lifting plate 302 on the side of the second carrier 207. The guide hole on the lifting plate 302 restricts the movable range of the measuring rod 303 that can contact the cement concrete. The anti-detachment plate connected to the measuring rod 303 and the limiting rod 305 respectively prevents the lifting plate 302 from accidentally separating from the limiting rod 305 and prevents the measuring rod 303 from falling off the lifting plate 302. The loading plate 304 with mounting holes provides a mounting position for the non-contact displacement sensor 306, so that the detection end of the displacement sensor 306 can pass through the mounting hole and be aligned with the upper end of the measuring rod 303, thereby measuring the height change of the measuring rod 303 and transmitting the measured data outward in the form of a signal.

[0039] In this embodiment, the cement concrete to be tested is placed in the slump cylinder 4 for testing, which is a well-known prior art in this field, so it will not be described in detail here.

[0040] Working principle: When this device is installed for cement concrete slump detection, after the displacement sensor 306 is connected to the external signal processing and display equipment, a measuring rod 303 of appropriate length is selected. The length is such that when the second carrier 207 is lowered to the lowest position, the lower edge of the measuring rod 303 is flush with the upper edge of the slump cylinder 4 when it contacts the detection table 1, and the measuring rod 303 and the slump cylinder 4 do not interfere with each other during the subsequent operation of this device.

[0041] Based on this, during testing, cement concrete is injected through a funnel into the slump cylinder 4, which is in contact with the testing platform 1, and vibrated. After the slump cylinder 4 is filled, the cement concrete at the open end of the slump cylinder 4 is smoothed. Then, the electric actuator 301 can be activated to simultaneously adjust the height of the first support frame 206 and the second support frame 207. Since the limiting groove on the first upright 202 is composed of two vertical sections with non-overlapping horizontal projections and a covering section, when the first support frame 206 drives the slump cylinder 4 to rise, the slump cylinder 4 separates from the cement concrete. During the process of the second support frame 207 driving the measuring component 3 to descend, the first support frame 206 will drive the slump cylinder 4 to rotate horizontally, causing the measuring component 3 to be misaligned with the slump cylinder 4. Therefore, the descent of the measuring component 3 and subsequent measurements will not be affected by the slump cylinder 4.

[0042] Based on this, when the measuring component 3 descends to its lowest position along with the second carrier 207, the electric actuator 301 can be activated to adjust the height of the lifting plate 302 relative to the second carrier 207, so that the lifting plate 302 drives the measuring rod 303 to descend further. After the measuring rod 303 descends to the height of contact with the cement concrete, even if the electric actuator 301 continues to drive the lifting plate 302 to descend, the height of the measuring rod 303 will not change. At this time, the displacement of the measuring rod 303 from its initial position measured by the displacement sensor 306 is the amount of cement concrete slump.

[0043] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
