Description

Technical Field

[0001] The invention relates to the field of rock mass weathering rate measurement, and in particular to a device for measuring the weathering rate of a slope rock mass. Background Art

[0002] Slope refers to the slope surface with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. It can be divided into artificial slope and natural slope.

[0003] Weathering refers to the whole process in which hard rocks and minerals on or near the surface undergo physical and chemical changes in contact with the atmosphere, water and organisms, forming loose deposits in situ.

[0004] The measurement of rock weathering rate can be completed by simulating outdoor environment. This simulation test can control variables such as temperature and humidity to simulate the outdoor environment, so as to conduct accelerated weathering tests on rock samples. These simulation test methods help to evaluate and predict the weathering rate of rocks in natural environments in a shorter period of time, which is of great significance for understanding the rock weathering process and protecting stone cultural relics.

[0046] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0047] As described in the background art, the greater the wind force required during the experiment, the greater the external kinetic energy required by the fan, which is more consuming of external energy.

[0048] In order to solve this technical problem, the present invention provides a device for measuring the weathering rate of a slope rock mass, which is applied to the measurement of the weathering rate of a rock mass.

[0051] The device for measuring the weathering rate of slope rock mass provided by the present invention provides a driving mechanism to drive a fan to rotate so as to weather the rock sample placed on a supporting platform; and provides a position adjustment mechanism so as to drive the fan to move in a horizontal direction. If the wind force needs to be increased, the fan is driven to move closer to the supporting platform to be closer to the rock sample. Thus, the wind force on the rock sample can be increased while the fan rotation speed remains unchanged.

[0056] Specifically, the support platform 3 can simply be used to support the rock sample, or it can be a support platform with a weighing function, which can directly weigh the rock sample before and after weathering, so as to calculate the weathering rate of the rock sample later.

[0057] The driving mechanism 5 includes a limiting rod 501 fixed between the two side walls of the U-shaped experimental table 1, and the limiting rod 501 is penetrated by a rectangular frame 502 which is slidably connected to it, and the rectangular frame 502 is penetrated by an internal threaded sleeve 503 which is rotatably connected to it, and a gear 1 504 is rotatably connected to the inner wall of the rectangular frame 502, and the gear 1 504 is driven by an external motor, and the internal threaded sleeve 503 is sleeved with a gear 2 505 which meshes with the gear 1 504.

[0058] Example 2, the measuring device for the weathering rate of the slope rock mass provided in Example 1 is further optimized, specifically, as follows Figure 1-Figure 5 As shown, the position adjustment mechanism 6 includes two vertical poles 601 vertically fixed in the U-shaped experimental table 1 and symmetrically distributed, and an internal spline shaft 602 is rotatably connected between the two vertical poles 601. The two ends of the internal spline shaft 602 respectively pass through the two vertical poles 601, and a threaded rod 603 passing through the internal threaded sleeve 503 is sleeved on the internal spline shaft 602.

[0059] The two ends of the inner spline shaft 602 are telescopically connected with the outer spline shaft 604 , and the ends of the two outer spline shafts 604 away from the inner spline shaft 602 are integrally fixed with round shafts 605 , and the two round shafts 605 are vertically fixed with limiting rods 606 .

[0060] Specifically, the outer spline shaft 604 can rotate along with the inner spline shaft 602 and can also move in the horizontal direction.

[0061] L rods 607 are fixed on both side walls of the U-shaped test bench 1, and the two L rods 607 are symmetrically distributed. The free ends of the two L rods 607 are telescopically connected with plug rods 608, and the free ends of the plug rods 608 are fixedly connected with inclined stoppers 609. A spring 6010 mounted on the plug rods 608 is fixedly connected between the L rods 607 and the inclined stoppers 609.

[0062] The inclined surfaces of the two inclined surface stoppers 609 are oriented in different directions, wherein the inclined surface of one inclined surface stopper 609 faces upwards, and the inclined surface of the other inclined surface stopper 609 faces downwards;

[0063] One of the limiting rods 606 and the corresponding inclined surface stopper 609 are located on the same horizontal plane, and the inclined surface stopper 609 limits the limiting rod 606 to rotate in only one direction, such as Figure 3 As shown;

[0064] Another limiting rod 606 and the corresponding inclined surface stopper 609 are not on the same horizontal plane and are in a mutually disengaged state. The inclined surface stopper 609 cannot limit the rotation direction of the limiting rod 606. Figure 5 As shown;

[0065] Positioning rods 6011 are vertically fixed to the two opposite side walls of the U-shaped experimental table 1, and a same linkage rod 6012 is telescopically inserted between the two positioning rods 6011. The linkage rod 6012 passes through the rectangular frame 502. A through hole for the linkage rod 6012 to pass through is opened on the surface of the rectangular frame 502, and the diameter of the through hole is slightly larger than the diameter of the linkage rod 6012, so that no friction is generated between the rectangular frame 502 and the linkage rod 6012 when it moves horizontally. An annular sleeve 6014 rotatably connected to the two circular shafts 605 is sleeved, and a cross bar 6013 is fixedly connected between the two annular sleeves 6014 and the linkage rod 6012, respectively.

[0066] By providing the annular plate 6015 , the rectangular frame 502 can drive the linkage rod 6012 to move horizontally by pushing the annular plate 6015 during the horizontal movement.

[0067] Example 3, the measuring device for the weathering rate of the slope rock mass provided in Example 1 or 2 is further optimized, specifically, as follows Figure 6-Figure 9 As shown, a rectangular box 7 is fixedly installed on the U-shaped test bench 1, and the side of the rectangular box 7 close to the supporting platform 3 is an open structure, and the side of the rectangular box 7 away from the supporting platform 3 is provided with multiple first air outlets 701, and a first filter 702 is fixedly installed in each of the first air outlets 701.

[0068] The rectangular box 7 is provided to collect sand and dust when the fan 4 weathers the rock sample.

[0069] A conversion assembly 8 is arranged in the rectangular box 7 .

[0070] The conversion assembly 8 includes a partition 801 slidably connected to the inner wall of the rectangular box 7 with upper and lower limits, a second air outlet 802 corresponding to the first filter 702 is opened on the surface of the partition 801, a second filter 803 is fixedly installed in the second air outlet 802, a baffle 804 is inserted into the bottom surface of the rectangular box 7, a connecting rod 805 is fixedly connected between the baffle 804 and the partition 801, two symmetrically distributed inclined strip frames 806 are fixedly connected to the partition 801, and two symmetrically distributed L-shaped rod bodies 807 are fixedly connected to the lower surface of the rectangular frame 502, and the L-shaped rod body 807 is slidably adapted to the inclined strip frame 806;

[0071] The limit rod 501, the inner spline shaft 602, and the linkage rod 6012 all pass through the rectangular box 7 and the partition 801. The surface of the partition 801 is provided with three vertical grooves respectively connected to the limit rod 501, the inner spline shaft 602, and the linkage rod 6012, so that the up and down movement of the partition 801 is not affected.

[0072] Each blade of the fan 4 is inclined, and a water storage hole 808 is opened on each blade;

[0073] A U-shaped water tank 809 is integrally fixed between the inner walls of the two opposite sides of the rectangular box 7, and a pipe 1 8010 interconnected with the U-shaped water tank 809 is fixedly installed on one side of the surface of the rectangular box 7. Two symmetrically distributed support plates 8011 are vertically fixed on the U-shaped experimental table 1, and sliding grooves 8012 are provided on the two support plates 8011. Rectangular sliders 8013 are slidably connected in the sliding grooves 8012, and rotating shafts 8014 are rotatably connected to the two rectangular sliders 8013. A water outlet funnel 8015 is fixedly connected between the two rotating shafts 8014, and a pipe 2 8016 is inserted into the side wall of the water outlet funnel 8015. A hose is installed between the pipe 2 8016 and the pipe 1 8010, and the hose is not shown in the figure.

[0074] Embodiment 4: The measuring device for the weathering rate of the slope rock mass provided in the above embodiments is further optimized, such as Fig.10 As shown, a drying mechanism 9 is arranged above the U-shaped experimental table 1 .

[0075] The drying mechanism 9 includes a spiral heating resistance wire 901 fixedly installed in the water outlet funnel 8015. By setting the spiral heating resistance wire 901, the water source can flow along the heating resistance wire 901, so that the water flow is more stable. The two rotating shafts 8014 are both sleeved with gear three 902, and the two support plates 8011 are both fixed with racks 903 that mesh with gear three 902. The sliding groove 8012 is installed with an electric telescopic rod two 904, and the rectangular slider 8013 is fixedly installed on the electric telescopic rod two 904.

[0076] The use process of the device for measuring the weathering rate of the slope rock mass provided by the present invention is as follows:

[0077] Before use, select a suitable rock sample and place the rock sample on the supporting platform 3;

[0078] In the initial state, the rectangular frame 502 is against the surface of one of the annular plates 6015. Figure 2 As shown, at this time, one of the limiting rods 606 and the corresponding inclined surface stopper 609 are located on the same horizontal plane, and the inclined surface stopper 609 limits the limiting rod 606 to rotate in only one direction, such as Figure 3 As shown;

[0079] Another limiting rod 606 and the corresponding inclined surface stopper 609 are not on the same horizontal plane and are in a mutually disengaged state. The inclined surface stopper 609 cannot limit the rotation direction of the limiting rod 606. Figure 5 As shown;

[0080] The external motor is started to drive the gear 1 504 to rotate clockwise, and the gear 1 504 can drive the gear 2 505 meshing with it to rotate counterclockwise, and the gear 2 505 can drive the fan 4 to rotate counterclockwise through the internal thread sleeve 503, so that the fan 4 generates wind to weather the rock sample;

[0081] The dust blown out by the fan 4 will be collected by the rectangular box 7;

[0082] At this time, the threaded rod 603 also rotates counterclockwise with the internal threaded sleeve 503, and the threaded rod 603 can drive the internal spline shaft 602 to rotate counterclockwise, and the internal spline shaft 602 can drive the round shaft 605 to rotate counterclockwise through the external spline shaft 604, and the round shaft 605 can drive the limiting rod 606 to rotate counterclockwise. One of the limiting rods 606 can gradually push the corresponding inclined surface of the inclined surface stopper 609 during rotation, pushing the inclined surface stopper 609 to move closer to the L rod 607, so that the limiting rod 606 can rotate counterclockwise smoothly. Figure 3 As shown;

[0083] When the wind force needs to be increased, the gear 1 504 is driven by an external motor to rotate counterclockwise, and the gear 1 504 can drive the gear 2 505 to rotate clockwise, and the gear 2 505 can drive the internal threaded sleeve 503 to rotate clockwise. However, at this time, one of the limiting rods 606 is restricted by the corresponding inclined surface block 609 and cannot rotate clockwise, so the circular shaft 605, the external spline shaft 604, the internal spline shaft 602 and the threaded rod 603 cannot rotate clockwise. Then the internal threaded sleeve 503 can drive the fan 4 to rotate clockwise and move closer to the supporting platform 3, so that the fan 4 is closer to the rock sample.

[0084] When the fan 4 moves to a suitable position, it continues to rotate counterclockwise to generate wind force, thereby enabling the fan 4 to increase the wind force on the rock sample without changing the rotation speed;

[0085] When a rain test is required for the rock sample, the fan 4 is driven to move horizontally into the rectangular box 7. Figure 6 As shown, at this time, the L-shaped rod 807 on the surface of the rectangular frame 502 will gradually move into the inclined strip frame 806, as shown in FIG. Figure 8 As shown, the L-shaped rod 807 continues to move toward the side of the partition 801, which can push the inclined strip frame 806 to move upward, and the inclined strip frame 806 can drive the partition 801 to move upward, so that the second air outlet 802 on the surface of the partition 801 and the first air outlet 701 on the surface of the rectangular box 7 are staggered. At the same time, the partition 801 can drive the baffle 804 to move upward through the connecting rod 805, and water can be stored in the rectangular box 7 at this time.

[0086] When the rectangular frame 502 pushes one of the annular plates 6015 to make the linkage rod 6012 move toward the side close to the partition 801, the linkage rod 6012 can drive the circular shaft 605 to move along with it through the cross bar 6013 and the annular sleeve 6014, and the circular shaft 605 can drive the limiting rod 606 to move along with it, so that the limiting rod 606 and the inclined surface stopper 609 that were originally on the same plane are separated, and the limiting rod 606 and the inclined surface stopper 609 that were originally separated from each other are in the same plane;

[0087] At this time, the fan 4 can continue to rotate counterclockwise, and the threaded rod 603 can also rotate counterclockwise accordingly. The water storage hole 808 on the fan 4 will be filled with water when it rotates to the water in the rectangular box 7. As the water storage hole 808 rotates, the open side will gradually face downward, pouring the water into the U-shaped water storage tank 809, and then flowing into the water outlet funnel 8015 through the pipe 1 8010, the hose, and the pipe 2 8016 in sequence, and then flowing onto the rock sample through the water outlet funnel 8015. The spiral heating resistance wire 901 in the water outlet funnel 8015 can guide the water to make the water flow more stable.

[0088] When the wet rock needs to be dried, the rectangular slider 8013 is driven downward by the electric telescopic rod 2 904. The rectangular slider 8013 can drive the water outlet funnel 8015 to move downward through the rotating shaft 8014. At the same time, when the gear 3 902 moves downward, it will rotate due to the restriction of the rack 903. The gear 3 902 drives the water outlet funnel 8015 to rotate ninety degrees through the rotating shaft 8014 and continue to move downward, so that the water outlet funnel 8015 can finally cover the wet rock sample and heat and dry it through the heating resistance wire 901.
