Description

Technical Field

[0001] This utility model relates to the field of hydropower engineering technology, specifically to an integrated traction machine for slope rolling of panel rockfill dams. Background Technology

[0002] For concrete-faced rockfill dams, the slope surface of the dam face cushion material needs to be compacted first when the dam is filled to the design elevation. Slope compaction is a core process to ensure the density and stability of the dam body. Specifically, a 10-ton vibratory slope roller is generally used for compaction. The compaction method involves parking an excavator near the dam face at the top of the dam. The excavator serves as an anchor point, using its own weight and working device as a fixing device. A redirecting pulley is hung in the upper part of the excavator's boom. One end of the wire rope is connected to the slope roller, and the other end is fixed to the winch at the dam axis end or to the tail of the bulldozer at the top of the dam after passing through the redirecting pulley. Before compaction begins, the excavator's boom is erected and the excavator's bucket is placed horizontally on the ground, i.e., the dam top ground, as a support for fixation. The slope roller moves up and down to compact the material under the traction force generated by the forward or backward movement of the winch or bulldozer. When changing the compaction position during the compaction process, the ramp roller must first descend to the bottom of the dam, then the boom is raised to lift the bucket off the dam crest. The excavator is then moved laterally to the next position. Finally, the excavator's bucket is brought horizontally to the ground, and the ramp roller is moved up and down by the traction force generated by the winch or bulldozer moving forward or backward. This process is repeated until the entire concrete-faced rockfill dam slope is compacted.

[0003] The disadvantages of this method are that it requires the excavator to work in conjunction with a winch or bulldozer, necessitating the simultaneous operation of both machines. Furthermore, setting up a winch or bulldozer traction cable on the dam crest occupies other working areas, impacting construction on those areas and increasing costs. Moreover, bulldozer traction lacks precision in slope turning and speed control; using a winch requires an additional anchoring system, resulting in poor flexibility. Consequently, the two machines must work closely together, making operator coordination difficult, and causing lag in traction speed and direction control, affecting compaction efficiency and uniformity. Utility Model Content

[0004] To solve the aforementioned technical problems, this utility model provides a new integrated traction and traction machine for slope rollers used in rockfill dams. It utilizes the excavator's own hydraulic system as power, with a hydraulic winch installed at the excavator's counterweight position. A pulley assembly is installed at the connection between the boom and the top of the stick. The traction wire rope passes from the winch through the pulley assembly and is fixed to the slope roller. During operation, the excavator's tracks travel in the direction of the dam's axis, the boom is upright, and the bucket is placed horizontally on the dam surface. The hydraulic control system is activated, and the hydraulic winch is operated to pull the slope roller up and down to compact the dam surface subbase material. Furthermore, when a small movement of the compaction position is required, the lifting force of the excavator's boom and stick is used to lift the slope roller off the ground (slope surface) for relocation. Then, compaction can be resumed by simply rotating the boom.

[0005] This utility model provides a panel rockfill dam slope roller traction integrated machine, including an excavator, a hydraulic winch and a slope roller. The hydraulic winch is located at the rear of the excavator. A redirecting pulley assembly is provided at the connection between the top of the excavator's boom and the arm. One end of the wire rope is connected to the slope roller, and the other end is connected to the hydraulic winch after passing through the pulley assembly.

[0006] A further technical solution is: the redirecting pulley assembly includes two pulley seats, an axle, and a redirecting pulley. The two pulley seats are detachably connected to the two side walls at the top of the stick, and the redirecting pulley is sleeved on the axle. The two pulley seats are connected to both ends of the axle.

[0007] A further technical solution is that the redirecting pulley can slide left and right relative to the axle, with a sliding distance of 20-40 centimeters.

[0008] A further technical solution is that the two pulley seats are respectively connected to the top of the stick by bolts.

[0009] A further technical solution is: the hydraulic winch is located at the original counterweight position of the excavator, and the original counterweight is moved to the rear of the excavator.

[0010] A further technical solution is to install additional counterweights on both sides of the hydraulic winch.

[0011] A further technical solution is: the excavator is a 37.5-ton excavator, the hydraulic winch is a 10-ton hydraulic winch, and the ramp roller is a 10-ton ramp roller.

[0012] A further technical solution is to connect the hydraulic winch's hydraulic system to the excavator's hydraulic system for control.

[0013] The beneficial effects of this utility model are as follows: It completely eliminates the need for additional traction equipment (bulldozers or winches). A single modified excavator integrates three major functions: fixed anchor point, traction power source, and compaction actuator control (via stick fine-tuning). It significantly improves work efficiency: eliminating waiting and adjustment time associated with multi-equipment coordination, allowing for single-operator control, rapid response, and more precise and consistent compaction paths. It drastically reduces costs, saving the long-term occupation costs of a bulldozer or winch and its operator; significantly reducing fuel consumption (only one piece of equipment operating), labor costs (reducing one operator), and maintenance costs (reducing the maintenance of one set of traction equipment); simplifying on-site equipment scheduling and management complexity; and significantly reducing the space requirements at the top / toe of the slope for single-machine operation. The stick directional pulley design allows for flexible adjustment of the traction angle to adapt to different slope ratios and local terrain changes. Furthermore, during construction, equipment transfer and positioning are faster, reducing the risk of cross-operation between equipment; the operator's field of vision is concentrated, providing stronger control over the entire compaction process (vibratory roller, wire rope, slope conditions).

[0014] This utility model of a panel rockfill dam slope compaction and traction integrated machine represents a major breakthrough in the traditional panel rockfill dam slope compaction process. It has extremely high technical and economic value and application prospects, and represents an important direction for the mechanized construction of water conservancy and hydropower projects towards high efficiency, intensiveness, and intelligence. It can be promoted and applied in subsequent engineering practices. Attached Figure Description

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model.

[0019] like Figure 1-4 As shown, the present invention provides a panel rockfill dam slope roller traction integrated machine 100, including an excavator 10, a hydraulic winch 20 and a slope roller 30. At the connection between the top of the excavator's boom 11 and the arm 12, that is, near the head of the hydraulic cylinder push rod 14, a redirecting pulley assembly 50 is provided. One end of the wire rope 40 is connected to the slope roller 30, and the other end is connected to the hydraulic winch 20 after passing through the pulley assembly 50. The hydraulic winch 20 is mounted on the excavator 10, and the hydraulic system of the hydraulic winch 20 is connected to the hydraulic system of the excavator 10 for control.

[0020] In one embodiment, the redirecting pulley assembly includes two pulley seats 51, an axle 52, and a redirecting pulley 53. A wire rope 40 connects to the redirecting pulley 53. The two pulley seats 51 are detachably connected to the top two side walls of the boom 11, and the redirecting pulley 53 is fitted onto the axle 52. Both ends of the axle 50 are connected to the two pulley seats 51. Specifically, the two pulley seats 51 are connected to the top of the boom 11 by bolts 54. When the redirecting pulley assembly needs to be disassembled, the bolts are unscrewed to separate the entire assembly from the boom. The bolted connection method allows for quick installation and disassembly without affecting other conventional functions of the excavator. In this invention, the redirecting pulley assembly guides the wire rope from the winch to the vibratory roller on the slope, while simultaneously changing the direction of the force. Meanwhile, since the pulley assembly is fixed to the top of the boom, the controllable extension and swing of the boom allows for dynamic adjustment of the traction angle. This ensures that the wire rope remains perpendicular to the slope or maintains the optimal traction angle during compaction, resulting in effective compaction. This greatly optimizes traction efficiency and significantly reduces the unbalanced lateral force on the excavator, minimizing the lateral load and unbalanced torque on the excavator, thus improving operational stability and equipment durability.

[0021] In a more specific embodiment, the redirecting pulley 53 can slide left and right relative to the axle 52, with a sliding distance of 20-40 cm. The purpose of this left-right sliding relative to the axle is that, given the short distance between the pulley and the winch drum, when the wire rope is on one side of the drum, the angle between the wire rope and the center of the pulley should not exceed 1.5 degrees (an angle greater than 1.5 degrees would cause the wire rope or pulley side to bite, which is not permitted in lifting regulations). Therefore, designing the pulley to automatically slide within a certain range solves this problem.

[0022] In some embodiments, the hydraulic winch 20 is located at the position of the original counterweight 15 of the excavator, which is moved to the rear of the excavator. Moving the original counterweight slightly rearward allows space for the installation of the hydraulic winch. This design ensures the basic stability of the excavator 10. In a more preferred embodiment, additional counterweights 16 are provided on both sides of the hydraulic winch 20. In one specific embodiment, the addition of these additional counterweights 16 brings the total weight of the hydraulic winch and counterweights to 4 tons. This compensates for any possible shift in the center of gravity due to the rearward movement of the original counterweight, and balances the additional overturning moment caused by the new hydraulic winch and its traction load (slope roller), especially during slope operations. This ensures the static and dynamic stability of the entire panel rockfill dam slope roller traction machine during slope traction operations. Therefore, the rearward shift of the counterweight plus an additional 4 tons of counterweight effectively balances the overturning moment generated by the hydraulic winch, wire rope, and slope rolling operation, ensuring the stability and safety of the excavator, especially the 37.5-ton class excavator, when towing a 10-ton load on a slope.

[0023] In this invention, the selected excavator 10 is a 37.5-ton excavator, the selected hydraulic winch 20 is a 10-ton hydraulic winch, and the selected ramp roller 30 is a 10-ton ramp roller. All three devices are commercially available standard equipment. The selected wire rope 40 has a diameter of 32mm, a 6x37 wire structure, and a length of 150 meters.

[0024] When the slope compaction construction is carried out, the hydraulic winch 20 of the integrated traction machine 100 for rockfill dams is designed to have a traction speed of 2400-3000 m / h (approximately 40-50 m / min).

[0025] like Figure 5As shown, when the panel rockfill dam slope roller traction machine 100 of this utility model is in operation, the excavator tracks 17 travel in the direction of the dam axis 60, the boom 11 is upright, and the bucket 13 is placed horizontally at a distance of 61 from the top surface of the dam. The hydraulic control system is activated, and the hydraulic winch 20 is operated to pull the slope roller 30 up and down to compact the subbase material on the dam slope 62. Furthermore, when it is necessary to move the compaction position slightly, the lifting force of the excavator boom 12 and boom 11 is used to lift the slope roller 30 off the ground (slope 62) for relocation, and then compaction is carried out. Thus, slight changes in the construction position can be achieved simply by rotating the boom 12.
