Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, in particular to a high-efficiency road roller used in construction engineering. Background Art

[0002] In the field of road construction and civil engineering, the importance of road rollers as basic compaction equipment is self-evident. Road rollers compact soil, sand and gravel and other basic materials through different compaction methods to ensure the stability and bearing capacity of the foundation or road. With the continuous advancement of engineering technology, the types and functions of road rollers are also constantly enriched and expanded.

[0003] In the large family of road rollers, tamping machines, as a special compaction equipment, have received more and more attention in recent years. Tamping machines use impact force to compact the soil. They are particularly suitable for clay soil, wet soil and other soils that are difficult to compact with traditional rollers. Its appearance makes up for the problem of insufficient compaction effect of traditional rollers under specific soil conditions.

[0004] A dust-proof plate compactor disclosed in Chinese patent publication number CN104164826A, the dust-proof plate compactor, the motor drives the rotating shaft to rotate, so that the eccentric block rotates, the eccentric block can provide vibration force for the plate when rotating, and then the soil, sand and gravel and other basic materials are compacted by the vibration of the plate.

[0005] However, compared with the existing technologies in related fields, existing rollers usually move forward at a constant speed during compaction operations. This method may work well when dealing with uniform base materials, but when the roller encounters soft base materials, due to the fast forward speed, the vibration force cannot be adjusted, which may lead to insufficient compaction times, thereby failing to fully expel the air and moisture in the base material, affecting the compaction effect. On the contrary, when the roller works on a harder base material, it may cause excessive compaction, which not only increases energy consumption, but also may damage the structure of the base material. Since the forward speed cannot be adjusted automatically, the operator needs to manually adjust the speed of the roller based on experience, which not only increases the complexity of the operation, but also reduces the operating efficiency.

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 are within the scope of protection of the present invention.

[0022] Additional aspects and advantages of the present invention will be further given in the following description in conjunction with the accompanying drawings, and in part will become apparent from the following description, or may be learned through practice of the present invention.

[0023] An embodiment of a high-efficiency road roller for construction engineering of the present invention is shown in Figures 1 to Fig. 9As shown, it includes a pressing plate 1, a bracket 2 is fixedly installed on the top of the pressing plate 1, and an armrest 3 is fixedly installed on the bracket 2. The side of the bracket 2 close to the armrest 3 is defined as the rear side. The interior of the bracket 2 is hinged with a mounting frame 5 through a hinge assembly 4. The front and rear sides of the mounting frame 5 are connected to the inner wall of the bracket 2 through an elastic traction assembly 6. A driving member 7 is fixedly installed inside the mounting frame 5. The driving member 7 has two output ends. Both output ends of the driving member 7 are provided with a vibration generating assembly 8. When the output end of the driving member 7 drives the vibration generating assembly 8 to rotate, the centrifugal force generated by the vibration generating assembly 8 will cause the pressing plate 1 to vibrate. Both left and right sides of the mounting frame 5 are provided with an adjusting assembly 9 for adjusting the centrifugal force of the vibration generating assembly 8. The bottom of the bracket 2 is provided with a feedback assembly 10 for detecting the hardness of the base material. When the base material is loose, the feedback assembly 10 will transmit a signal to the adjusting assembly. The hinge component 9 is then used to increase the centrifugal force generated by the vibration generating component 8. When the base material is harder, the feedback component 10 will transmit the signal to the adjusting component 9, and then the adjusting component 9 will be used to reduce the centrifugal force generated by the vibration generating component 8. The left and right sides of the bracket 2 are fixedly installed with a third cover plate 202. The third cover plate 202 is set to enclose the hinge component 4, the mounting frame 5, the elastic traction component 6, the driving component 7, the vibration generating component 8, the adjusting component 9 and the feedback component 10 to prevent dust from affecting their normal operation. The driving component 7 is a double-headed motor, and a centrifugal regulator is installed inside the driving component 7. The output of the double-headed motor can be adjusted by the centrifugal regulator according to the change of the speed of the double-headed motor. The purpose of installing a centrifugal regulator is to automatically adjust the operating state of the double-headed motor according to the change of the speed to meet specific functional requirements.

[0024] As shown in FIG. 6 , the vibration generating assembly 8 includes a mounting box 801 fixedly mounted on the output end of the driving member 7 , a first magnetic block 802 is slidably disposed inside the mounting box 801 , and a first cover plate 8011 is fixedly mounted on the mounting box 801 .

[0025] As shown in Figures 3 to 5, the adjustment component 9 includes an annular shell 901 fixedly mounted on the mounting frame 5, a plurality of second magnetic blocks 902 are slidably arranged inside the annular shell 901, a second cover plate 9011 is fixedly mounted on the annular shell 901, a plurality of second magnetic blocks 902 surround the annular shell 901 to form a ring, hydraulic cylinders 903 are fixedly arranged at positions corresponding to the plurality of second magnetic blocks 902 on the outer surface of the annular shell 901, hydraulic rods 904 are slidably arranged inside the plurality of hydraulic cylinders 903, the ends of the hydraulic rods 904 are fixedly connected to the second magnetic blocks 902, and the hydraulic rods 904 are away from the second A second piston 9041 is fixedly provided at one end of the magnetic block 902, and the second piston 9041 is connected to the hydraulic cylinder 903 by a second elastic member 9042. The hydraulic rod 904 is used to control the second magnetic block 902 to slide inside the annular shell 901. An annular tube 905 is fixedly provided at one end of the hydraulic cylinders 903 away from the annular shell 901, and the hydraulic cylinders 903 are all connected to the annular tube 905. The magnetic poles of the first magnetic block 802 and the second magnetic blocks 902 are the same, so that the first magnetic block 802 can be controlled to slide inside the installation box 801 by adjusting the positions of the second magnetic blocks 902.

[0026] As shown in FIGS. 2 and 8 , a mounting groove 201 is provided on the front side of the bottom of the bracket 2. The feedback assembly 10 includes a hydraulic pipe 1001 fixedly installed inside the mounting groove 201. A first piston 1002 is slidably provided inside the hydraulic pipe 1001. A guide rod 1003 is fixedly installed on the first piston 1002. The guide rod 1003 extends from the inside of the hydraulic pipe 1001 and passes through the front side of the pressure plate 1. A first elastic member 1004 is provided inside the hydraulic pipe 1001. The first elastic member 1004 is arranged on the rear side of the first piston 1002. As shown in FIGS. 7 to 8 , Fig. 9 As shown, the two annular tubes 905 are connected to the hydraulic tube 1001 through the hose 1005. The hydraulic tube 1001, the hose 1005, the annular tube 905 and the hydraulic cylinder 903 are all provided with hydraulic oil. The cross-sectional shape of the guide rod 1003 is rhombus-shaped. The pressure plate 1 is provided with a movable groove at the position corresponding to the guide rod 1003. The rhombus-shaped guide rod 1003 can be used to have a ground-breaking effect during vibration, thereby avoiding the guide rod 1003 from getting stuck during use.

[0027] In summary, as shown in Figures 1, 3, 6, 8 and Fig. 9As shown, when the base material is soft, the guide rod 1003 is subject to less resistance, and then the guide rod 1003 only causes the first piston 1002 to squeeze the first elastic member 1004 to slide a short distance inside the hydraulic pipe 1001. At this time, the hydraulic oil inside the hydraulic pipe 1001 is sequentially introduced into the plurality of hydraulic cylinders 903 through the hose 1005 and the annular tube 905, and then the second piston 9041 is caused to squeeze the second elastic member 9042 to control the hydraulic rod 904 to move a short distance, so that the plurality of second magnetic blocks 902 are close to one side of the installation box 801. When the plurality of second magnetic blocks 90 2 approaches one side of the installation box 801, the first magnetic block 802 and the plurality of second magnetic blocks 902 have the same magnetic pole, and the principle of like magnetic poles repel each other is used, so that the first magnetic block 802 is controlled to slide a short distance inside the installation box 801 by adjusting the positions of the plurality of second magnetic blocks 902. At this time, the vibration generating assembly 8 generates a large centrifugal force, the compaction strength of the pressing plate 1 will also increase accordingly, the rotation speed of the driving member 7 will decrease accordingly, and the travel speed of the device will also slow down accordingly, so as to increase the number of compaction times, fully discharge the air and moisture in the base material, and ensure the compaction effect; as shown in Figures 4 to Fig. 9 As shown, when the base material is harder, the guide rod 1003 is subjected to greater resistance, and then the guide rod 1003 will cause the first piston 1002 to squeeze the first elastic member 1004 to slide a long distance inside the hydraulic pipe 1001. At this time, the hydraulic oil inside the hydraulic pipe 1001 is sequentially introduced into the plurality of hydraulic cylinders 903 through the hose 1005 and the annular tube 905, and then the second piston 9041 is caused to squeeze the second elastic member 9042 to control the hydraulic rod 904 to move a long distance, so that the plurality of second magnetic blocks 902 are again close to one side of the installation box 801. When several second magnetic blocks 902 approach one side of the installation box 801, the first magnetic block 802 is controlled to slide a long distance inside the installation box 801 by adjusting the positions of several second magnetic blocks 902 because the magnetic poles of the first magnetic block 802 and the several second magnetic blocks 902 are the same. At this time, the vibration generating component 8 generates a small centrifugal force, the tamping strength of the pressure plate 1 will also decrease, the rotation speed of the driving member 7 will increase, and the travel speed of the device will become faster, thereby reducing the number of compaction times and avoiding damage to the basic material structure due to excessive compaction.

[0028] As shown in Figures 2 to 6, the hinge assembly 4 includes a first hinge 401 fixedly mounted on the top wall of the inner part of the bracket 2, the first hinge block 402 is hinged inside the first hinge 401 through a rotating shaft, and the first hinge block 402 is connected to the installation frame 5 through a pull rod 403; the elastic traction assembly 6 includes a second hinge 601 fixedly mounted on the side of the installation frame 5, and a third hinge 602 is fixedly mounted on the side wall of the bracket 2 corresponding to the position of the second hinge 601, and the second hinge 601 and the third hinge 602 are internally connected. Each part is hinged with a second hinge block 603 through a rotating shaft, and two adjacent second hinge blocks 603 are connected by a third elastic member 604. The two vibration generating components 8 are driven to rotate by the driving member 7. When the vibration generating component 8 rotates, the centrifugal force generated by the vibration generating component 8 will be transmitted to the installation frame 5. At this time, the installation frame 5 will swing inside the bracket 2 through the hinge component 4, and then the installation frame 5 will vibrate the bracket 2 and the pressure plate 1 through the elastic traction component 6, so that the base material is compacted by the vibration of the pressure plate 1.

[0029] The centrifugal regulator, double-headed motor, hinge assembly 4 and elastic traction assembly 6 described in this application are well-known technologies in the technical field, so their specific structures and working principles are not described in detail.

[0030] The working process is as follows: S1. When in use, as shown in FIG. 2 and FIG. 6, the two vibration generating components 8 are driven to rotate by the driving member 7. When the vibration generating components 8 rotate, the centrifugal force generated by the vibration generating components 8 is transmitted to the mounting frame 5. At this time, the mounting frame 5 swings inside the bracket 2 through the hinge component 4. Then, the mounting frame 5 causes the bracket 2 and the pressing plate 1 to vibrate through the elastic traction component 6, thereby utilizing the vibration of the pressing plate 1 to compact the base material; S2, as shown in Figures 1, 3, 6, 8 and Fig. 9 As shown, when the base material is soft, the guide rod 1003 is subject to less resistance, and then the guide rod 1003 only causes the first piston 1002 to squeeze the first elastic member 1004 to slide a short distance inside the hydraulic pipe 1001. At this time, the hydraulic oil inside the hydraulic pipe 1001 is sequentially introduced into the plurality of hydraulic cylinders 903 through the hose 1005 and the annular tube 905, and then the second piston 9041 is caused to squeeze the second elastic member 9042 to control the hydraulic rod 904 to move a short distance, so that the plurality of second magnetic blocks 902 are close to one side of the installation box 801; S3, as shown in Figures 1, 3, 6, 8 and Fig. 9As shown, when the plurality of second magnetic blocks 902 approach one side of the installation box 801, the first magnetic block 802 and the plurality of second magnetic blocks 902 have the same magnetic pole, so that the first magnetic block 802 is controlled to slide a short distance inside the installation box 801 by adjusting the positions of the plurality of second magnetic blocks 902. At this time, the vibration generating assembly 8 generates a large centrifugal force, the compaction strength of the pressing plate 1 will also increase accordingly, the rotation speed of the driving member 7 will decrease accordingly, and the travel speed of the device will also slow down accordingly, thereby increasing the number of compaction times, fully discharging the air and moisture in the base material, and ensuring the compaction effect; S4, as shown in Figure 4 to Fig. 9 As shown, when the base material is harder, the resistance of the guide rod 1003 is greater, and then the guide rod 1003 will cause the first piston 1002 to squeeze the first elastic member 1004 to slide a long distance inside the hydraulic pipe 1001. At this time, the hydraulic oil inside the hydraulic pipe 1001 is sequentially introduced into multiple hydraulic cylinders 903 through the hose 1005 and the annular tube 905, and then the second piston 9041 is caused to squeeze the second elastic member 9042 to control the hydraulic rod 904 to move a long distance, so that the plurality of second magnetic blocks 902 are again close to one side of the installation box 801; S5, as shown in Figure 4 to Fig. 9 As shown, when the plurality of second magnetic blocks 902 approach one side of the installation box 801, the first magnetic block 802 and the plurality of second magnetic blocks 902 have the same magnetic pole, so that the first magnetic block 802 is controlled to slide a large distance inside the installation box 801 by adjusting the positions of the plurality of second magnetic blocks 902. At this time, the vibration generating assembly 8 generates a small centrifugal force, the compaction strength of the pressing plate 1 will also decrease, the rotation speed of the driving member 7 will increase, and the travel speed of the device will increase, thereby reducing the number of compaction times and avoiding damage to the basic material structure due to excessive compaction. S6, as shown in Figure 2 to Fig. 9 As shown, when the base material becomes soft again, the first elastic member 1004 will push the guide rod 1003 out of the hydraulic pipe 1001 through the first piston 1002, and then the first piston 1002 can suck the hydraulic oil in the hydraulic cylinders 903 back to the hydraulic pipe 1001 through the hose 1005 and the annular tube 905. At this time, through the second elastic member 9042, the second piston 9041 drives the hydraulic rod 904 and the second magnetic block 902 to move to the side away from the installation box 801. At this time, through the centrifugal force, the first magnetic block 802 can slide inside the installation box 801 to the side away from the output end of the driving member 7, so that the vibration generating component 8 can generate a large centrifugal force again.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
