Description

Technical Field

[0001] The invention relates to the technical field of roadbed detection, and in particular to a device for exploring the influence of a curing agent on a phosphogypsum roadbed. Background Art

[0002] Soil solidifier is a new type of energy-saving and environmentally friendly engineering material used to solidify various types of soil. For the soil to be reinforced, according to the physical and chemical properties of the soil, it only needs to add a certain amount of solidifier, mix well, and compact it to achieve the required performance indicators;

[0003] The roadbed is the foundation of a track or road surface, and is a geotechnical structure formed by excavation or filling. As a type of roadbed, the phosphogypsum roadbed can be strengthened by a curing agent, but different amounts of curing agent have different effects on the roadbed. Too much or too little curing agent will make the roadbed strength unqualified. Due to the different curing agent contents required for different soils, it is necessary to use a test device to prepare a suitable amount of curing agent when making roadbeds for different soils. The existing test device only has a roadbed strength detection function, and the staff is required to prepare the corresponding roadbed to be tested, and then transport the roadbed to the test device for testing. Since the roadbed is generally heavy and the transportation is more troublesome, it not only increases the workload of the staff but also reduces the test efficiency of the roadbed test. Therefore, a device for exploring the influence of curing agent on phosphogypsum roadbed is proposed to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the test device in the prior art only has the strength detection function of the roadbed but does not have the preparation function, which increases the workload of the staff and reduces the test efficiency of the roadbed, and proposes a device for exploring the influence of the curing agent on the phosphogypsum roadbed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A device for exploring the influence of a curing agent on a phosphogypsum roadbed, comprising a roadbed preparation test box and a detection mechanism arranged above the roadbed preparation test box, the bottom of the roadbed preparation test box being hollowed out, the side walls of the roadbed preparation test box being provided with a flip base which is rotated by a rotating shaft, the outer side wall of the roadbed preparation test box being provided with a flip motor for driving the flip base to flip, the detection mechanism comprising a U-shaped moving frame and a U-shaped mounting frame symmetrically arranged on the inner side of the U-shaped moving frame, a rolling assembly and a stirring assembly being arranged on the inner side of the U-shaped mounting frame, adjustment motors for driving the U-shaped mounting frame to rotate being installed on both sides of the U-shaped moving frame, and a conveying mechanism for driving the U-shaped moving frame to reciprocate being arranged above the U-shaped moving frame.

[0007] Preferably, a transmission gear is fixedly connected to the surface of the rotating shaft at one end of the flip base, and the transmission gears are meshed with each other to enable the flip base to rotate towards each other, so that the roadbed falls after detection.

[0008] Preferably, a telescopic groove is provided on the surface of the flip base, a magnetic ejection block is slidably connected to the inner side of the telescopic groove, and an elastic film is provided on the surface of the flip base.

[0009] Preferably, a magnetic partition plate is fixedly connected to the inner center of the roadbed preparation test box, and the magnetic partition plate and the magnetic ejection block are magnetically attracted to each other. When the flip base is flipped, the magnetic partition plate will magnetically attract the magnetic ejection block, so that the magnetic ejection block contacts the elastic membrane, causing the elastic membrane to bulge and expand, thereby facilitating the falling off of the broken roadbed.

[0010] Preferably, a mounting plate is fixedly connected to the inner center of the U-shaped mounting frame, and pushing cylinders are installed on both sides of the mounting plate. The stirring assembly includes a stirring motor slidably arranged on the inner wall of the U-shaped mounting frame and a stirring rod fixedly connected to the output end of the stirring motor, wherein the output end of one of the pushing cylinders is connected to the stirring motor.

[0011] Preferably, the rolling assembly comprises a fixing frame fixedly connected to the output end on the other side, and a pressure roller is rotatably connected to the inner side of the fixing frame.

[0012] Preferably, a pressure cylinder for controlling the lifting of the U-shaped movable frame is installed at the top of the U-shaped movable frame, and the conveying mechanism includes a movable motor and a conveying screw fixedly connected to the output end of the movable motor, and the output end of the conveying screw is threadedly connected to a nut block slidably connected to the U-shaped movable frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention is provided with a roadbed preparation test box, a pressure cylinder and a U-shaped mounting frame. The soil and the debugged soil curing agent are placed inside the roadbed preparation test box, and then the soil is stirred by a stirring assembly inside the U-shaped mounting frame. Then, the pressure cylinder is used to control the downward movement of the U-shaped mounting frame to realize the soil compaction function and the preparation function of the roadbed to be tested. Therefore, no other equipment is needed to prepare the roadbed to be tested, and the steps of transporting and conveying the roadbed are omitted, which greatly reduces the workload of the inspection personnel and improves the inspection efficiency.

[0015] 2. The present invention is provided with a conveying mechanism, a pressure cylinder, a U-shaped mounting frame and a rolling assembly. The rolling assembly on the inner side of the U-shaped mounting frame is extended, and then the pressure assembly is used to move the rolling assembly downward and squeeze the roadbed to be tested. Under the action of the conveying mechanism, the rolling assembly is made to reciprocate, thereby realizing the rolling function of the roadbed to be tested, and then realizing the strength detection function of the roadbed.

[0016] 3. The present invention is provided with a flip motor and a flip base, and the flip motor is used to drive the flip base to flip, so that the roadbed after detection can automatically fall off without the need for workers to clean it, thereby improving the detection efficiency of the roadbed.

DETAILED DESCRIPTION

[0024] The technical solutions 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, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Reference Figure 1-6A device for exploring the influence of a curing agent on a phosphogypsum roadbed comprises a roadbed preparation test box 1 and a detection mechanism arranged above the roadbed preparation test box 1, the bottom of the roadbed preparation test box 1 is hollowed out, a flip base 11 is arranged on the side wall of the roadbed preparation test box 1 through a rotating shaft, a flip motor 2 for driving the flip base 11 to flip is installed on the outer wall of the roadbed preparation test box 1; a transmission gear 10 is fixedly connected to the rotating shaft surface at one end of the flip base 11, and the transmission gears 10 are meshed with each other to enable the flip base 11 to rotate toward each other so that the roadbed falls after the detection, a telescopic groove 1101 is opened on the surface of the flip base 11, a magnetic ejection block 18 is slidably connected to the inner side of the telescopic groove 1101, and an elastic membrane 14 is arranged on the surface of the flip base 11.

[0026] A magnetic partition plate 15 is fixedly connected to the inner center of the roadbed preparation test box 1, and the magnetic partition plate 15 and the magnetic ejection block 18 are magnetically attracted to each other. When the flip base 11 is flipped, the magnetic partition plate 15 will magnetically attract the magnetic ejection block 18, so that the magnetic ejection block 18 contacts the elastic membrane 14, causing the elastic membrane 14 to bulge and expand, making it easier for the broken roadbed to fall off.

[0027] It should be noted that: the flip motor 2 is used to drive the flip base 11 to rotate, and under the action of the transmission gear 10, the flip bases 11 on both sides rotate towards each other and become inclined. Under the action of gravity, the roadbed after the inspection is completed automatically falls out of the roadbed preparation test box 1, and there is no need for manual cleaning by the staff, which reduces the workload and improves the roadbed inspection efficiency.

[0028] It should be noted that: when the magnetic ejection block 18 is facing the magnetic partition plate 15, under the action of magnetic attraction, the magnetic ejection block 18 moves and lifts up the elastic membrane 14, causing the elastic membrane 14 to bulge and expand. The surface adhesion of the expanded elastic membrane 14 decreases, making it easier for the crushed roadbed debris to fall off.

[0029] The detection mechanism includes a U-shaped movable frame 6 and a U-shaped mounting frame 8 symmetrically arranged on the inner side of the U-shaped movable frame 6, a rolling assembly and a stirring assembly are arranged on the inner side of the U-shaped mounting frame 8, and an adjustment motor 9 for driving the U-shaped mounting frame 8 to rotate is installed on both side surfaces of the U-shaped movable frame 6, and a conveying mechanism for driving the U-shaped movable frame 6 to reciprocate is arranged above the U-shaped movable frame 6.

[0030] It should be noted that the stirring assembly can achieve the function of stirring the soil, which is convenient for the preparation function of the roadbed to be tested. The pressure cylinder 4 drives the U-shaped mounting frame 8 to move downward, which can compact the soil and achieve the preparation function of the roadbed to be tested.

[0031] A mounting plate 12 is fixedly connected to the inner center of the U-shaped mounting frame 8, and a pushing cylinder 17 is installed on both sides of the mounting plate 12. The stirring assembly includes a stirring motor 16 slidably set on the inner wall of the U-shaped mounting frame 8 and a stirring rod 13 fixedly connected to the output end of the stirring motor 16, and one of the output ends of the pushing cylinder 17 is connected to the stirring motor 16.

[0032] It should be noted that: the U-shaped mounting frame 8 is driven to rotate by adjusting the motor so that the stirring assembly is facing downward, and then the stirring assembly is pushed out by the pushing cylinder 17, and then the pressure cylinder 4 is used to drive the U-shaped movable frame 6 to move downward, so that the stirring rod 13 extends to the inside of the soil, and under the action of the stirring motor 16, the stirring rod 13 is driven to rotate to realize the stirring function of the soil.

[0033] The rolling assembly includes a fixed frame fixedly connected to the output end on the other side, a pressure roller 7 is rotatably connected to the inner side of the fixed frame, a pressure cylinder 4 for controlling the lifting and lowering of the U-shaped moving frame 6 is installed at the top of the U-shaped moving frame 6, the conveying mechanism includes a moving motor 3 and a conveying screw 5 fixedly connected to the output end of the moving motor 3, the output end of the conveying screw 5 is threadedly connected to a nut block slidably connected to the U-shaped moving frame 6 (the bottom end of the nut block is fixedly connected to a guide rod, and the top end of the U-shaped moving frame 6 is provided with a sliding opening slidably connected to the guide rod).

[0034] It should be noted that: the pushing cylinder 17 is used to extend the rolling assembly, and then the pressure cylinder 4 is used to drive the U-shaped moving frame 6 to move downward, and the U-shaped moving frame 6 drives the rolling assembly to move downward, so that the pressure roller 7 squeezes the roadbed to be tested, and the mobile motor 3 is used to drive the conveying screw 5 to rotate, so that the nut block drives the U-shaped moving frame 6 to move back and forth, and the pressure roller 7 moves back and forth on the surface of the roadbed to be tested, thereby realizing the strength detection function.

[0035] When the present invention is used, soil is placed on both sides of the magnetic partition plate 15 in the roadbed preparation test box 1, and then different amounts of soil curing agent are added respectively. Then, the U-shaped mounting frame 8 is driven to rotate by the adjustment motor 9 so that the stirring assembly is facing downward, and then the pushing cylinder 17 is used to extend the stirring assembly, and the pressure cylinder 4 is used to drive the U-shaped moving frame 6 to move downward, so that the stirring plate extends to the inside of the soil, and the stirring motor 16 is turned on. The stirring motor 16 drives the stirring rod 13 to rotate, so as to achieve the stirring and mixing function of the soil and the soil curing agent;

[0036] Then the U-shaped moving frame 6 is reset, and the adjustment motor 9 is turned on again to make the rolling face downward, and the rolling assembly is extended by the pushing motor, and the rolling assembly is moved downward by the pressure cylinder 4, so that the pressure roller 7 can move downward to squeeze the roadbed to be tested, and then the moving motor 3 is turned on, and the moving motor 3 drives the conveying screw 5 to rotate, so that the nut block drives the U-shaped moving frame 6 to move back and forth, and then drives the pressure roller 7 to roll back and forth on the surface of the roadbed to be tested, so as to realize the strength detection function of the roadbed to be tested, thereby eliminating the need for other equipment to prepare the roadbed to be tested, omitting the steps of transporting and conveying the roadbed, greatly reducing the workload of the detection personnel, and improving the detection efficiency;

[0037] After the test is completed, by observing whether the surface of the roadbed to be tested is cracked and the degree of cracking, the influence of different contents of soil stabilizer on the roadbed can be known;

[0038] Finally, turning on the flip motor 2 can drive the flip base 11 to rotate, so that the flip bases 11 on both sides rotate toward each other into an inclined state. Under the action of gravity, the roadbed after the inspection is automatically dropped out of the roadbed preparation test box 1. When the magnetic ejection block 18 is facing the magnetic partition plate 15, under the action of magnetic attraction, the magnetic ejection block 18 moves and lifts up the elastic membrane 14, so that the elastic membrane 14 bulges and expands. The surface adhesion of the expanded elastic membrane 14 decreases, which facilitates the falling off of the crushed roadbed debris, thereby eliminating the need for manual cleaning by the staff, reducing the workload and improving the roadbed inspection efficiency.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
