Description

Technical Field

[0001] The utility model belongs to the technical field of road construction, in particular to a vibration excitation device for a road roller. Background Art

[0002] A road roller, also known as a soil compactor, is a piece of road construction equipment widely used for fill and compaction operations in large-scale projects such as high-grade highways, railways, airport runways, dams, and stadiums. It can compact sandy, semi-cohesive, and cohesive soils, roadbed stabilized soil, and asphalt concrete pavement layers. Using the force of its own gravity, the roller is suitable for various compaction operations, causing the compacted layer to undergo permanent deformation and become dense. Among various types of rollers, vibratory rollers are the most widely used. Vibratory rollers drive the rollers to vibrate through an excitation device, effectively increasing the density of the ground and thereby improving construction efficiency. However, they still have the following drawbacks in actual use:

[0003] The utility model with publication number CN202298426U discloses an excitation mechanism of a vibratory roller, wherein a limit block is provided in the inner cylinder of the fixed eccentric block, and the movable eccentric block is placed in the inner cylinder of the fixed eccentric block, and the two ends of the fixed eccentric block are respectively connected to a flange C and a flange D, each of which is provided with a blind hole inside the flange C and the flange D, and the two ends of the movable eccentric block are respectively installed on the blind holes of the flange C and the flange D. When the excitation mechanism is installed in the roller, it is usually installed at the center of the pressure roller. However, in actual use, since the excitation mechanism is at a certain distance from the position where the bottom of the pressure roller contacts the ground, the force generated by the excitation mechanism during operation will be transmitted to all angles of the pressure roller, making it difficult to act efficiently on the position where the pressure roller contacts the ground, and part of the energy is difficult to fully utilize. Moreover, the force transmitted to multiple positions for a long time is likely to cause wear of the bearings, pressure rollers, etc.

[0004] When a road roller is produced and processed, a vibration device of appropriate size is often ordered and installed according to its size. However, due to its small size and low customer demand, some road rollers are not equipped with a vibration device during the production process. However, during later use, due to changes in actual demand, the simple road roller may find it difficult to compact the ground efficiently. At this time, it is difficult to equip the vibration device of appropriate size, and it is also difficult to install the vibration device between the vibration device and the road roller. The use and loading and unloading of the vibration device is relatively inconvenient. Utility Model Content

[0005] The purpose of the utility model is to provide a vibration excitation device for a road roller. Through the vibrator housing and transmission components, the utility model solves the problems that when the vibration excitation device is used in the road roller, it is usually installed in the center of the road roller, the force generated during operation is difficult to fully utilize, and it is easy to cause wear of bearings, pressure rollers, etc. The vibration excitation device needs to be ordered and installed according to the size of the road roller, and is inconvenient to use and load and unload.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a road roller excitation device, comprising an exciter housing and a transmission assembly, wherein a drive shaft is inserted through one end of the exciter housing and clamped, a drive connecting rod is welded and fixed to one end of the drive shaft, a transmission assembly is attached to one end of the exciter housing, a lifting cylinder is provided on the top of the transmission assembly, and a drive rod is inserted through one side of the transmission assembly and clamped;

[0008] The two drive shafts can be connected by driving the connecting rod, so that the vibration device can connect multiple vibrator housings according to the size of the roller, so that the vibrator bodies in multiple vibrator housings can work synchronously, ensuring that the vibration device can be applied to rollers of various sizes and improving the flexibility of the device. When installing and using the vibration device, the lifting cylinder is installed at a suitable position on the surface of the roller, and the transmission assembly and the vibrator housing are driven to rise and fall through the lifting cylinder, so that the vibrator housing fits the bottom of the inner wall of the roller of the roller, so that the vibration generated by the vibration can quickly act on the ground through the bottom of the roller to compact the ground, avoiding the vibration device being far away from the bottom of the roller, and the force generated by the vibration acting on various positions of the roller, thereby ensuring the rolling efficiency.

[0009] Furthermore, a plurality of mounting connection grooves are provided at both ends of the outer circumference of the exciter housing, a slot is provided at one end of the exciter housing, one end of the drive shaft is inserted into the inner side of the slot, and the drive connecting rod is located in the slot;

[0010] By installing the connecting groove, multiple exciter shells can be connected, and the excitation area can be adjusted to ensure that the excitation device can be applied to rollers of various sizes, thereby improving the flexibility of use.

[0011] Furthermore, a drive connecting groove is formed at one end of the drive shaft, and the drive connecting groove is located at the other end of the drive shaft relative to the drive connecting rod, and one end of the drive shaft of the exciter housing is inserted into the inner side of the slot of the other exciter housing, and the drive connecting rod of one drive shaft is inserted into the inner side of the drive connecting groove of the other drive shaft;

[0012] By inserting the driving connecting rod into the driving connecting groove, the two driving shafts can be connected to each other. When the driving device drives one driving shaft to rotate, it can synchronously drive multiple driving shafts to rotate, ensuring that when multiple exciter housings are used, the excitation area of the excitation device is suitable for the corresponding roller.

[0013] Furthermore, a transmission gear is inserted through one end of one side of the transmission assembly, a mounting plate is welded and fixed to one side of the transmission assembly, a bolt is inserted through one side of the mounting plate, the bolt is screwed and fixed to one end of the exciter housing, and one end of the drive shaft is inserted through one side of the transmission gear;

[0014] By connecting the driving device and the driving rod, the driving device can further drive the transmission gear and the driving shaft to rotate through the driving rod and the transmission assembly, so that the vibration device can generate vibration and improve the compaction efficiency of the ground.

[0015] Furthermore, a shock-absorbing pad is fixedly connected to the top of the transmission assembly, a mounting bracket is connected to the top of the lifting cylinder, a telescopic tube is slidably connected to the bottom of the lifting cylinder, and the telescopic tube is connected to the top of the shock-absorbing pad;

[0016] The lifting cylinder can drive the vibrator housing and transmission assembly to move up and down. After the mounting frame is installed at a suitable position on the surface of the roller, the lifting cylinder is controlled to drive the vibrator housing and transmission assembly to move downward until the vibrator housing fits the bottom of the inner wall of the roller of the roller, so that the vibration generated by the excitation can quickly act on the ground through the bottom of the roller to compact the ground, avoiding the vibration device being far away from the bottom of the roller, and the force generated by the vibration acting on various positions of the roller, thereby ensuring the rolling efficiency. At the same time, the vibration device can be applied to rollers with various roller sizes, thereby improving the flexibility of use.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem that the excitation mechanism is usually installed at the center of the pressure roller when installed in the roller by arranging an exciter housing and a transmission assembly. However, in actual use, since the excitation mechanism is a certain distance away from the position where the bottom of the pressure roller contacts the ground, the force generated by the excitation mechanism during operation will be transmitted to various angles of the pressure roller, making it difficult to act efficiently on the position where the pressure roller contacts the ground, part of the energy is difficult to fully utilize, and the force transmitted to multiple positions for a long time is likely to cause wear of bearings, pressure rollers, etc. When installing the excitation device, after installing the mounting frame at a suitable position on the surface of the roller, the lifting cylinder is controlled to drive the exciter housing and the transmission assembly to move downward until the exciter housing fits against the bottom of the inner wall of the pressure roller of the roller, so that the vibration generated by the excitation acts quickly on the ground through the bottom of the pressure roller to compact the ground, thereby avoiding the excitation device being far away from the bottom of the pressure roller and the force generated by the vibration acting on various positions of the pressure roller, thereby ensuring the rolling efficiency.

[0019] The utility model solves the problem that, during the production and processing of the road roller, a vibration device of appropriate size is often ordered and installed according to the size of the road roller, while some road rollers are not equipped with a vibration device during the production process due to their small size and low customer demand. However, during later use, due to changes in actual needs, the simple road roller may find it difficult to compact the ground efficiently. At this time, it is difficult to equip the road roller with a vibration device of appropriate size, and it is also difficult to install the vibration device and the road roller, and the use and loading and unloading of the vibration device are relatively inconvenient. When purchasing the vibration device, it is only necessary to purchase a transmission assembly and an appropriate number of vibrator housings according to the size of the roller. During installation, multiple vibrator housings are connected and fixed, and multiple drive shafts are connected for transmission. Then, the vibrator bodies in multiple vibrator housings can be driven by the drive device to perform vibration operations, which is flexible and convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
