Description

Technical Field

[0001] The invention relates to the technical field of grouting testing, and in particular to a rapid material changing device for testing the anti-erosion performance of grouting materials. Background Art

[0002] Dynamic water disasters are common types of disasters in the construction and operation of rail transit projects, water conservancy and hydropower projects, mining projects, etc. They have the characteristics of strong disaster-causing ability and great difficulty in control, which seriously affect the safety of project construction and operation. Dynamic water grouting is a common measure for dynamic water disaster control, and dynamic water grouting materials are an important factor affecting the effect of dynamic water grouting. Dynamic water has an erosive effect on grouting materials. Grouting projects under dynamic water conditions require slurry properties that are very different from those of grouting materials under waterless or static water conditions. Not only are the materials required to be able to condense and solidify normally underwater, but the grouting materials are also required to have anti-erosion properties, so that the grouting materials can be retained and solidified in the stratum, so as to achieve the purpose of controlling dynamic water disasters such as water gushing and water inrush. Therefore, rapid and efficient testing of the anti-erosion properties of grouting materials has important theoretical and practical significance for the development and application of dynamic water grouting engineering materials.

[0003] At present, when testing the dynamic water erosion resistance of grouting materials, the grouting materials are mainly placed directly in a test water tank, and the grouting materials after dynamic water erosion are taken out and weighed to determine the loss of grouting materials, and other parameters of the grouting materials are tested and recorded to evaluate the anti-erosion performance of the grouting materials.

[0050] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technicians in this field can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0051] Example:

[0052] like Figures 3 to 6As shown, the present invention provides a rapid material replacement device for testing the erosion resistance of grouting materials, so as to replace the grouting materials in the test tank 105, comprising a frame 101, a lifting frame 401 which can be lifted and lowered is provided on the frame 101, a bearing frame 601 is provided in the lifting frame 401, a guide rod 104 is provided on the frame 101, a lifting frame 301 connected by a weighing component is provided on the lifting frame 401, a guide sleeve 303 is provided on the lifting frame 301, and the guide sleeve 303 is slidably sleeved on the guide rod 104, and a weighing component is weighed. The component includes an abutment rod 304 arranged on the lifting frame 301, a mounting rod 305 is arranged at the end of the abutment rod 304, a limit block 306 is arranged at the end of the mounting rod 305, the diameter of the mounting rod 305 is smaller than the abutment rod 304, a mounting frame 402 is arranged on the lifting frame 401, the mounting frame 402 is slidably sleeved on the mounting rod 305 and can abut against the abutment rod 304, and also includes a tension sensor 307, one end of the tension sensor 307 is connected to the mounting frame 402, and the other end is connected to the lifting frame 301.

[0053] When in use, the grouting material to be tested is placed on the bearing frame 601, wherein the lifting frame 301 is positioned by the cooperation of the guide sleeve 303 and the guide rod 104, so that the lifting frame 401 can be lifted and lowered on the frame 101. When the lifting frame 401 descends to the lowest point, it drives the bearing frame 601 to descend into the test water tank 105. Dynamic water is supplied to the test water tank 105 to test the grouting material in the bearing frame 601. And the abutment rod 304 applies downward pressure to the mounting frame 402 to prevent the lifting frame 401 from moving in the test water tank 105.

[0054] After the test is completed, the lifting frame 301 can be controlled to rise. During the rising process, the lifting frame 301 drives the lifting frame 401 and the supporting frame 601 to rise through the tension sensor 307, so as to move the tested grouting material out of the test water tank 105. In the process of putting in and removing the grouting material, the change in weight of the grouting material before and after can be known through the data displayed by the tension sensor 307, so as to know the loss of the grouting material. There is no need to weigh the grouting material separately after the test, which improves the convenience during the test.

[0055] like Figure 1 , 3As shown in Figures 4 and 8, in the present embodiment, a driving motor 107 is arranged on the frame 101, and a driving mechanism for converting the rotation of the output shaft of the driving motor 107 into driving the lifting frame 401 to lift is also arranged on the frame 101, and the driving mechanism includes four groups of rotatable sprockets 102 arranged on the frame 101, and the four groups of sprockets 102 are connected by chains 103, and the output shaft of the driving motor 107 is connected to one group of sprockets 102, and a connecting frame 501 is rotatably arranged on the chain 103, and a driving column 502 is arranged on the connecting frame 501, and a guide rail 302 is arranged on the lifting frame 301, and the driving column 502 is slidably clamped in the guide rail 302.

[0056] The driving mechanism controls one set of sprockets 102 to rotate to drive the chain 103 to move. The chain 103 drives the remaining sets of sprockets 102 to rotate during the movement, and makes the connecting frame 501 move along the arrangement track of the chain 103. The driving column 502 on the connecting frame 501 can slide in the guide track 302, so that the connecting frame 501 can drive the lifting frame 401 to rise and fall through the cooperation between the driving column 502 and the guide track 302 during the movement, and when the lifting frame 401 is lifted to the highest point and the lowest point, the driving motor 107 continuously rotates to control the driving column 502 to slide in the guide track 302. The setting of the driving mechanism can realize automatic control of the lifting frame 401 and the carrying frame 601 to move out and into the test tank 105.

[0057] like Figure 4 , 5 As shown in FIGS. 6 and 8, in this embodiment, the lifting frame 401 is provided with a discharge mechanism connected with the carrying frame 601, and when the lifting frame 401 rises to the highest point, the rotation of the output shaft of the driving motor 107 is converted into driving the carrying frame 601 to slide out of the lifting frame 401 through the discharge mechanism. The discharge mechanism includes an L-shaped frame 504, a push plate 505 and a clamping frame 503, one end of the L-shaped frame 504 is slidably connected with the lifting frame 401, and the other end is overlapped on the lifting frame 301, the push plate 505 is hinged at the end of the L-shaped frame 504, and a stopper 506 for limiting the unidirectional rotation of the push plate 505 is provided at the end of the L-shaped frame 504, and the clamping frame 503 is arranged on the connecting frame 501, and one end of the L-shaped frame 504 is clamped in the clamping frame 503 in a liftable manner.

[0058] When the lifting frame 401 moves to the highest point, the connecting frame 501 moves in translation, driving the L-shaped frame 504 to slide on the lifting frame 401, and the push plate 505 cannot rotate under the action of the stop block 506, thereby pushing out the bearing frame 601 on the lifting frame 401, so as to facilitate the bearing frame 601 loaded with the grouting material to be tested to be placed on the lifting frame 401 again. When the lifting frame 401 descends to the lowest point, the connecting frame 501 slides in the opposite direction, which can drive the push plate 505 to rotate and disengage from the abutment with the bearing frame 601 and then translate to reset in preparation for the next unloading.

[0059] like Figures 1 to 3 As shown, in this embodiment, a replacement mechanism is provided on the frame 101, through which the tested bearing frame 601 is received and the bearing frame 601 to be tested is moved to the lifting frame 401. The replacement mechanism includes a first driving roller 202 and a second driving roller 206 rotatably provided on the frame 101, a first conveyor belt 203 is provided on the first driving roller 202, the first driving roller 202 is connected to one set of sprocket wheels 102 through a first belt driving structure 201, a second conveyor belt 207 is provided on the second driving roller 206, and the second driving roller 206 is connected to one set of sprocket wheels 102 through a second belt driving structure 205. When the lifting frame 401 rises to the highest point, the first conveyor belt 203 and the second conveyor belt 207 are flush with the receiving surface of the lifting frame 401.

[0060] In the process of the lifting frame 401 moving to the highest point and unloading the supporting frame 601 through the unloading mechanism, the first driving roller 202 and the second driving roller 206 are respectively controlled to rotate by the first belt driving structure 201 and the second belt driving structure 205, and the unloaded supporting frame 601 is moved out by the second conveyor belt 207 in a moving state, and the supporting frame 601 above it is transferred to the supporting frame 601 by the first conveyor belt 203 in a moving state, without the need for manual loading and unloading, which effectively improves the test effect and reduces the labor during the test process.

[0061] like Figure 1 , 3 As shown, in this embodiment, multiple groups of limiting plates 204 are arranged at intervals on the first conveyor belt 203, and multiple groups of bearing frames 601 to be tested are arranged at intervals on the first conveyor belt 203 and abut against the limiting plates 204. Multiple bearing frames 601 loaded with grouting materials to be tested are placed at intervals on the first conveyor belt 203, and their spacing is controlled so that the conveying bearing frames 601 are located at the edge of the first conveyor belt 203 each time the lifting frame 401 rises to the highest point. In the process of conveying the bearing frames 601, the limiting plates 204 push the ends of the bearing frames 601 to move them onto the lifting frame 401, so that multiple grouting material samples can be quickly and automatically tested, further improving the test efficiency.

[0062] like Figure 2 , 3 As shown in FIGS. 6 and 7 , in this embodiment, a limit seat 106 is provided in the test water tank 105. After the lifting frame 401 is lowered into the test water tank 105, the limit seat 106 abuts against the lifting frame 401 and the carrying frame 601. The limit seat 106 is provided to prevent the carrying frame 601 from being displaced on the lifting frame 401 due to excessive water flow during the test, thereby preventing interference with subsequent loading and unloading. The lifting frame 401 is provided with a roller 403, and the carrying frame 601 is provided on the roller 403. By setting the roller 403, the friction between the lifting frame 401 and the supporting frame 601 can be reduced, thereby reducing the energy consumption of loading and unloading, and the supporting frame 601 can move a certain distance under the action of inertia when entering the lifting frame 401, so that the supporting frame 601 is located in the central area of ​​the lifting frame 401, so that when the L-shaped frame 504 is reset to the end of the supporting frame 601, the push plate 505 flips downward until it contacts the stop block 506, further avoiding interference with subsequent loading and unloading.

[0063] Specific usage and beneficial effects of the present invention:

[0064] When the device is in use, the lifting frame 401 receives the supporting frame 601, injects grouting material into the supporting frame 601, and supplies water into the test water tank 105 to perform a simulation test on the anti-erosion performance of the grouting material. After the experiment, the driving motor 107 can be controlled to start, and the driving motor 107 can be started to control the lifting frame 401 to rise through the driving mechanism. When the lifting frame 401 rises to the highest point, the rotation of the output shaft of the driving motor 107 can be converted into driving the supporting frame 601 to slide out of the lifting frame 401 through the unloading mechanism. The group of supporting frames 601 that slide out are carried by the changing mechanism, and the supporting frame 601 to be tested is moved to the lifting frame 401 through the changing mechanism, and then the lifting frame 401 is continued to be controlled to descend through the driving mechanism to continuously test multiple grouting material samples. The erosion resistance of the grouting material can be more accurately known through multiple groups of data. In the process of continuous testing, the tester only needs to place the supporting frame 601 containing the grouting material on the changing mechanism at intervals, without the need for cumbersome loading and unloading processes, which greatly reduces the work intensity of the tester. At the same time, the supporting frame 601 can be placed and disassembled during the test to improve the work efficiency of continuous testing of multiple samples.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments. On the basis of the present invention, some modifications or improvements can be made thereto, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
