Description

Technical Field

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

[0002] Slump is a method and index for measuring the workability of concrete. In construction sites and laboratories, slump tests are usually carried out to measure the fluidity of the mixture, and the cohesiveness and water retention are evaluated by intuitive experience. Slump is a quantitative index used to judge whether construction can proceed normally.

[0003] After retrieval, the utility model with the publication number CN217717760U discloses a concrete slump detection device, including a concrete slump detection device and a funnel. The funnel is located at the top of the concrete slump detection device. At the bottom of both sides of the funnel, there are fixed connection shells, and docking grooves are opened at the bottom of the shells. Through the combined use of the concrete slump detection device, the funnel, the shell, the docking groove, the docking block, the positioning groove, the positioning component and the control component, the user connects the concrete slump detection device and the funnel through the cooperation between the control component and the positioning component, and then positions them through the positioning component, solving the problem that when the existing concrete slump detection device is in use, the funnel needs to be inserted into the top of the concrete slump detection device. Since the connection relationship between the two is only a simple insertion, it is very easy to shake due to instability, thus affecting the accuracy of the data detected by the concrete slump detection device; although this device can improve the stability between the funnel and the slump cone, when lifting the slump cone, it is manually grasped by hand and lifted upward. During the lifting process, it cannot be guaranteed that the cylinder will not shift left and right, which will affect the accuracy of the concrete slump detection result. Secondly, when this detection device is in use, it is directly placed on the first relatively horizontal plate, and the levelness is difficult to guarantee, which will still affect the detection result. Therefore, this device still has certain deficiencies. Utility Model Content

Detailed Embodiment

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0023] Refer to Figures 1 - 4, a concrete slump detection device, including a bottom plate 100 and a slump cone 200 arranged on the top of the bottom plate 100. An integrated funnel is arranged at the top of the slump cone 200. Positioning and guiding columns 101 are arranged on the top of the bottom plate 100. A positioning connection assembly 300 is arranged between the positioning and guiding columns 101 and the slump cone 200. Support feet 400 for adjusting the levelness of the bottom plate 100 are arranged on both sides of the bottom plate 100. Among them, the positioning connection assembly 300 includes a connecting plate 301 fixedly connected to the slump cone 200 and slidably connected to the positioning and guiding columns 101, a connecting sleeve 302 slidably arranged on the outer wall of the positioning and guiding columns 101, and an elastic connecting piece 303 arranged between the connecting plate 301 and the connecting sleeve 302 to improve the tightness between the slump cone 200 and the bottom plate 100. During use, the levelness of the bottom plate 100 is adjusted through the support feet 400 to prevent the slump cone 200 from being in an inclined state during use, which may affect the accuracy of slump detection. Subsequently, the connecting plate 301 and the elastic connecting piece 303 are sleeved on the positioning and guiding columns 101 to drive the bottom of the slump cone 200 to abut against the bottom plate 100. Under the elastic force of the elastic connecting piece 303, the bottom of the slump cone 200 can be tightly abutted against the top of the bottom plate 100, preventing the concrete inside from leaking through the gap between the slump cone 200 and the bottom plate 100 and affecting the test results. With the cooperation of the arranged positioning and guiding columns 101, it can prevent the slump cone 200 from shifting left and right when it is lifted upward, which may affect the test results.

[0024] Refer to Figures 1 - 4 , the elastic connecting piece 303 includes an L-shaped connecting rod 304 with one end fixedly connected to the inner side of the connecting sleeve 302, the other end passing through the connecting plate 301 and extending downward, and an elastic member 305 sleeved on the outer wall of the L-shaped connecting rod 304. Here, the L-shaped connecting rod 304 can not only serve as a connecting rod but also as a lifting handle to lift the slump cone 200.

[0025] A first limit block 306 and a second limit block 307 are respectively arranged at the bottom end and the outer wall of the L-shaped connecting rod 304. The elastic member 305 is fixedly arranged between the connecting plate 301 and the second limit block 307.

[0026] Through holes are arranged on the outer walls of the positioning and guiding columns 101 and the connecting sleeve 302, and positioning pins 308 are inserted into the through holes.

[0027] An ear plate 201 is arranged on the side of the slump cone 200, and a positioning column 202 matching the ear plate 201 is arranged on the top of the bottom plate 100. The cooperating ear plate 201 and positioning column 202 can further improve the fixing effect of the slump cone 200.

[0028] During use, move the connecting plate 301 and the connecting sleeve 302 downward along the positioning guide post 101 until the positioning guide post 101 communicates with the through hole on the outer wall of the connecting sleeve 302. Then insert the positioning pin 308 into the through hole for fixation. During fixation, the elastic member 305 is compressed. Under the action of the elastic force of the elastic member 305, the slump cone 200 and the bottom plate 100 are tightly abutted against each other. Then pour the concrete to be tested into the slump cone 200 and vibrate it with a vibrator. After vibration, pull out the positioning pin 308 and pull the L-shaped connecting rod 304 to drive the slump cone 200 to move upward along the positioning guide post 101. When moving, the slump cone 200 can be prevented from deflecting left and right, thereby improving the accuracy of the concrete slump test data. After moving the slump cone 200 away, measure it with a measuring scale. This is an existing mature technology, so no more redundant description will be given.

[0029] Refer to Figures 1 - 3 , the support feet 400 include fixing plates 401 arranged on both side parts of the bottom plate 100, screws 402 penetrating through the fixing plates 401, foot pads 403 arranged at the bottoms of the screws 402, and threaded seats 404 arranged at the tops of the fixing plates 401 and threadedly connected to the screws 402. A handle 405 is further arranged at the top of the screw 402. During use, by rotating the handle 405, under the action of the threaded seat 404 and the screw 402, the foot pad 403 can be driven to move upward or downward relative to the bottom plate 100, so as to adjust the levelness of the bottom plate 100, ensure the levelness of the slump cone 200, and avoid affecting the accuracy of the test data due to its inclined state.

[0030] Specifically, when this concrete slump test device is in use: by rotating the handle 405, drive the screw 402 to rotate, and cooperate with the arranged threaded seat 404 to drive the foot pad 403 to move upward or downward relative to the bottom plate 100, adjust the levelness of the bottom plate 100, ensure the levelness of the slump cone 200, and avoid affecting the accuracy of the test data due to its inclined state. Move the connecting plate 301 and the connecting sleeve 302 downward along the positioning guide post 101 until the positioning guide post 101 communicates with the through hole on the outer wall of the connecting sleeve 302. Then insert the positioning pin 308 into the through hole for fixation. During fixation, the elastic member 305 is compressed. Under the action of the elastic force of the elastic member 305, the slump cone 200 and the bottom plate 100 are tightly abutted against each other, which can prevent leakage during the pouring of the concrete. Then pour the concrete to be tested into the slump cone 200 and vibrate it with a vibrator. After vibration, pull out the positioning pin 308 and pull the L-shaped connecting rod 304 to drive the slump cone 200 to move upward along the positioning guide post 101. When moving, the slump cone 200 can be prevented from deflecting left and right, thereby improving the accuracy of the concrete slump test data. After moving the slump cone 200 away, measure it with a measuring scale.
