Description

Technical Field

[0001] This invention relates to the field of compactor roller technology, specifically to an adjustable weight compactor roller for a roadbed compactor. Background Technology

[0002] In roadbed compaction construction, the rationality of the counterweight of the compaction roller directly affects the compaction effect. It needs to be flexibly adjusted according to parameters such as the characteristics of the roadbed material and the compaction thickness. The compaction roller of the compactor with adjustable counterweight has outstanding advantages such as low cost, convenient operation and precise control of counterweight increment. It does not require additional complex mechanical counterweight structure. Therefore, it is widely used in compaction projects such as highways, municipal roads and railway subgrades, and has become the preferred counterweight solution for small and medium-sized compaction equipment.

[0003] A search revealed that patent CN222809982U discloses a compaction device for slope surfaces. The compaction device includes: a compaction roller assembly comprising compaction rollers and a rotating shaft rotatably connected to the compaction rollers; multiple liquid storage chambers within the compaction rollers, each with a liquid injection port; a traction vehicle comprising a vehicle body and wheels rotatably connected to the vehicle body; a traction device mounted on the vehicle body and connected to the rotating shaft to drive the compaction rollers to roll on the slope surface; and a counterweight box mounted on the vehicle body and located on the side of the traction device away from the compaction rollers, containing multiple counterweight liquid storage chambers, each with a counterweight liquid injection port. The multiple roller liquid storage chambers and the multiple counterweight liquid storage chambers correspond one-to-one. The weight of the compaction roller and the counterweight box can be flexibly adjusted, and the adjustment of the weight of the compaction roller and the counterweight box does not require additional measurement work.

[0004] In existing technologies, when the counterweight of the compaction wheel is adjusted by water injection, the water inside the compaction wheel lacks effective restraint. During the compaction machine's movement and turning, or when facing an uneven roadbed surface, the water is prone to violent shaking, causing the overall center of gravity of the compaction wheel to shift frequently and irregularly. This instability of the center of gravity will result in uneven pressure distribution at the contact surface between the compaction wheel and the roadbed, reducing the uniformity of roadbed compaction. It will also cause the compaction machine to shake and reduce steering accuracy. In complex working conditions such as mountain slopes and curved sections, it may even increase the safety risk of equipment tilting, seriously restricting construction quality and work efficiency.

[0005] In view of this, we propose an adjustable weight roller for a roadbed compactor to solve the existing problems. Summary of the Invention

[0006] The purpose of this invention is to provide an adjustable counterweight compaction wheel for a roadbed compactor to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an adjustable counterweight compaction wheel for a roadbed compactor, comprising a cylinder, a main shaft, an adjustment assembly, and a counterweight assembly. The cylinder is a hollow cylindrical structure, with one end of the cylinder being open and the other end being closed. Two cylinders are provided, and the closed sides of the two cylinders are fixedly connected. A main shaft is fixedly installed at the center of the cylinder; Anti-slip strips are welded at equal intervals on the sides of the cylinder; Three sets of adjustment components are installed at equal intervals inside the cylinder; A counterweight assembly is installed between two adjacent sets of the adjustment components.

[0008] Preferably, the mixing component includes a water tank, and a water pipe is fixedly installed on the side of the water tank facing the opening of the cylinder.

[0009] Preferably, a flow meter is fixedly installed at the connection point between the water pipe and the water tank, and a water valve is fixedly installed at one end of the flow meter. A quick connector is provided at the end of the water pipe away from the water tank.

[0010] Preferably, a fixing plate is fixedly installed on the side of the water tank away from the water pipe. Several water-blocking plates are installed on the side of the fixing plate facing the water pipe by several springs, and a sealing ring is fitted at the contact position between the water-blocking plates and the water tank.

[0011] Preferably, the counterweight assembly includes several plugs, one end of which is fixedly connected to the inner wall of the cylinder, and a counterweight block is fitted on the outer side of the plug.

[0012] Preferably, the counterweight is equipped with a pull ring via a rope on the side facing the cylinder opening, and the pull ring is embedded inside the counterweight.

[0013] Preferably, two cover plates are bolted to one side of the opening of the cylinder, and both cover plates are semi-circular in structure.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention features a water-separating plate installed inside the water tank, connected to a fixed plate by a spring. After water is filled into the tank, the water-separating plate, under the elastic force of the spring, pushes the water inside the tank towards the water pipe, thereby expelling air from the tank and continuously applying pressure to the water, keeping the water stable and preventing it from sloshing around. This further enhances the overall stability of the compaction wheel while retaining the ability to flexibly adjust the counterweight.

[0015] This invention installs the counterweight component and the adjustment component inside the cylinder through a plug-in method, enabling modular and rapid installation of the entire rolling wheel and quick adjustment of the counterweight. Compared with traditional adjustable counterweight rolling wheels, it can significantly shorten the installation and disassembly time of the rolling wheel, thereby improving the efficiency of the rolling wheel in the assembly and disassembly process during actual use.

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 - Figure 11 As shown, the present invention proposes an adjustable counterweight compaction wheel for a roadbed compactor, comprising a cylinder 1, a main shaft 3, an adjustment assembly 4, and a counterweight assembly 5. The cylinder 1 is a hollow cylindrical structure, with one end of the cylinder 1 being open and the other end being closed. Two cylinders 1 are provided, and the closed sides of the two cylinders 1 are fixedly connected. The cylinder 1 can be connected to the compactor via the main shaft 3. By connecting the main shaft 3 and the bearing, the compactor can drive the cylinder 1 to rotate, thereby compacting the roadbed and achieving the compaction treatment of the roadbed. A main shaft 3 is fixedly installed at the center of the cylinder 1; the main shaft 3 can be connected to the compactor through bearings, and the compactor can push the main shaft 3, so that the main shaft 3 and its outer structure move synchronously with the compactor, thereby compacting the roadbed. Anti-slip plates 2 are welded at equal intervals on the side of the cylinder 1; the anti-slip plates 2 can increase the friction between the cylinder 1 and the roadbed, thereby preventing the device from sliding during use and preventing the cylinder 1 from sliding on the roadbed surface and causing damage to the roadbed. Three sets of adjustment components 4 are installed at equal intervals inside the cylinder 1; the adjustment components 4 can flexibly adjust the counterweight of the compaction wheel by injecting water, and can also expel the air in the water tank 401 during the water injection process to avoid the overall center of gravity of the compaction wheel becoming unstable after water injection, so as to improve the compaction effect of the compaction wheel on the roadbed. A counterweight assembly 5 is installed between two adjacent sets of adjustment components 4; the counterweight assembly 5 can adjust the weight of the rolling wheel by using multiple sets of counterweight blocks 501, thereby cooperating with the adjustment components 4 to adjust the counterweight of the rolling wheel according to the usage requirements during actual use.

[0020] Furthermore, the mixing component 4 includes a water tank 401, on which a water pipe 405 is fixedly installed; the water tank 401 can provide installation positions for surrounding components, and the water tank 401 can store a certain amount of water, thereby adjusting the counterweight of the rolling wheel by water injection; the water pipe 405 can facilitate water injection and drainage into the water tank 401.

[0021] Furthermore, a flow meter is fixedly installed at the connection point between the water pipe 405 and the water tank 401, and a water valve is fixedly installed at one end of the flow meter. A quick-connect interface is provided at the end of the water pipe 405 away from the water tank 401. The flow meter is a DATA-2811 type, which can detect the water flow inside the water pipe 405, thereby determining the water volume inside the water tank 401. The water valve can control the opening and closing of the water pipe 405 to facilitate the filling and emptying of water into the water tank 401.

[0022] Furthermore, a fixing plate 402 is fixedly installed inside the water tank 401 on the side away from the water pipe 405. Several water-separating plates 404 are installed on the side of the fixing plate 402 facing the water pipe 405 via several springs 403, and a sealing ring is fitted at the contact position between the water-separating plate 404 and the water tank 401. The fixing plate 402 can fix one end of the spring 403, so that the spring 403 can apply elastic force to the water-separating plate 404. Through the elastic force applied by the spring 403 to the water-separating plate 404, the water-separating plate 404 can move inside the water tank 401, thereby adaptively adjusting the water storage space. This can prevent the water inside the water tank 401 from shaking after water is filled, and improve the stability of the rolling wheel after water filling and counterweighting.

[0023] Furthermore, the counterweight assembly 5 includes several plugs 502, one end of which is fixedly connected to the inner wall of the cylinder 1, and a counterweight block 501 is fitted on the outer side of the plug 502; the plug 502 can limit the counterweight block 501, so that the counterweight block 501 can be inserted and installed inside the cylinder 1. By installing different numbers of counterweight blocks 501 inside the cylinder 1, the overall weight of the compaction wheel can be adjusted, thereby compacting the roadbed to different degrees according to different usage requirements.

[0024] Furthermore, a pull ring 503 is installed on the side of the counterweight 501 facing the opening of the cylinder 1 via a rope, and the pull ring 503 is embedded inside the counterweight 501; the pull ring 503 can provide a handhold position for the counterweight 501, thereby facilitating the installation or removal of the counterweight 501 inside the cylinder 1.

[0025] Furthermore, two cover plates 101 are bolted to one side of the opening of the cylinder 1, and both cover plates 101 are semi-circular structures. The cover plates 101 can limit the components installed inside the cylinder 1, preventing the internal structure from falling or shifting during the rolling process of the cylinder 1, and further ensuring the stability of the center of gravity of the rolling wheel during the working process.

[0026] Working principle: After the main shaft 3 is installed, the counterweights 501 are evenly distributed inside the cylinder 1 according to actual needs until the weight of the counterweights 501 is insufficient to meet the counterweight requirements. Then, water is added to the water tanks 401 one by one. When the water tanks 401 are not yet filled with water, the baffle plate 404 is in contact with one end of the water pipe 405 under the elastic force of the spring 403, which is state one. Water is added to the three water tanks 401 simultaneously, and the amount of water added to the three water tanks 401 is consistent. When water enters the water tanks 401 through the water pipe 405, the flow meter measures the amount of water entering the water tanks 401. 4. Simultaneously affected by water pressure and the elastic force applied by spring 403, it slides inside water tank 401. After water filling is completed, water with air bubbles is pushed into water tank 401 until the air bubbles are completely discharged from water tank 401. The water valve on water pipe 405 is closed to keep the water inside water tank 401 stable. At this time, the state inside water tank 401 is state two. Water tank 401 is installed inside cylinder 1, and then the two cover plates 101 are installed by bolts to complete the counterweight and installation of the compaction wheel. The compaction machine drives the compaction wheel to rotate as a whole, so that the compaction wheel rolls on the top of the roadbed to achieve the compaction treatment of the roadbed.

[0027] The above specific embodiments are merely several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
