Description

A compactor hammer that can be easily replaced and a high-speed hydraulic compactor

Technical Field

The utility model relates to the technical field of high-speed hydraulic compaction, in particular to a compaction machine rammer which is easy to replace and a high-speed hydraulic compaction machine.

Background technique

The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

A high-speed hydraulic compactor is a device that uses the impact force generated by a hydraulic cylinder to compact the soil. It is usually composed of three parts: a hydraulic power system, a control system, and a hammer body. The hydraulic power system includes an engine, oil storage, and a hydraulic pump. The control system includes a man-machine operation table, a manual-automatic switching device, and a control device. The hammer body includes a rammer and a hydraulic cylinder. The principle of a high-speed hydraulic compactor is to inject a large amount of hydraulic oil into the hydraulic cylinder to move the piston rapidly, thereby generating a huge impact force. This impact force is transmitted to the rammer of the compactor, causing the rammer to move downward at a high speed, exerting a strong impact and compression on the soil, thereby making the soil more compact. That is, the high-speed hydraulic compactor uses the fuselage configuration to output hydraulic power. By lifting the rammer to a specific high speed, with the help of a hydraulic energy storage device, a hydraulic booster device, and the rammer's own gravity, it accelerates down at a speed greater than the free fall of the rammer, and through uninterrupted compaction and striking, the compaction of the soil is ensured.

High-speed hydraulic compactors are widely used in highway engineering. At present, there are various improvements on high-speed hydraulic compactors. For example, patent CN116411560A proposes a high-speed hydraulic compactor for handling soft soil raised in pits, so that the soil and rocks adhering to the bottom of the rammer can be shaken off in time; patent CN219157625U proposes a high-speed hydraulic compactor that can separate the electric hydraulic rod and the rammer when tamping the ground to avoid impact on the electric hydraulic rod; patent CN116065429A proposes a high-speed hydraulic compactor with adjustable height to solve the problem of post-construction deformation control of high-speed railway ballastless track subgrade, etc. However, when the existing high-speed hydraulic compactor is used for compaction during the reconstruction and expansion of highways, it is usually necessary to replace the rammers of different sizes according to the construction plan, and the existing compactor rammer replacement steps are cumbersome and time-consuming, which affects the work efficiency. At present, there is no high-speed hydraulic compactor with fast replacement of rammers suitable for highway reconstruction and expansion construction.

Embodiment 1

Considering that during the reconstruction and expansion of expressways, the two commonly used high-speed hydraulic compacting machine rammers are rammers with a diameter of 1.25m (rammers are hammer structures, usually cylinders with a lower bottom diameter larger than the upper bottom diameter, the diameter here is the lower bottom diameter, the same below) and rammers with a diameter of 1.5m. In order to facilitate the replacement of these two sizes of rammers, the utility model discloses a compacting machine rammer that is easy to replace, which can meet the switching of rammers with diameters of 1.25m and 1.5m. For rammer construction that requires frequent replacement of rammers of different sizes, it greatly saves construction time, and also avoids the situation where the high-speed hydraulic compacting machine moves redundantly to replace the rammer, resulting in poor rammering effect.

The utility model proposes a compacting machine rammer that is easy to replace, as shown in Figure 1, including a main rammer plate 1, a plurality of hydraulic connecting rods 3 and a plurality of extended rammer plates 2. Among them, the main rammer plate 1 is a cylindrical structure with a lower bottom surface diameter greater than the upper bottom surface diameter and a lower bottom surface diameter of 1.25m. A lifting ring 4 is provided on the side of the main rammer plate 1, and the lifting ring 4 is connected to one end of an iron chain, and the other end of the iron chain is fixedly connected to the bottom of the outer protective shell 6 of the rammer, that is, the main rammer plate 1 is connected to the bottom of the outer protective shell 6 of the rammer through the lifting ring and the iron chain on the lifting ring; a hydraulic cylinder is provided in the outer protective shell of the high-speed hydraulic rammer, and the hydraulic cylinder is connected to the main rammer 11. The main rammer plate 1 is located directly below the main rammer 11. During the hydraulic rammering process, the lower bottom surface of the main rammer plate 1 contacts the ground at the ramming point, and the main rammer 11 is driven by the hydraulic cylinder to hit the main rammer plate 1, thereby completing the ramming operation. The expansion ramming plate 2 is an arc-shaped plate with a thickness of 0.25m. The diameter of the arc-shaped plate gradually increases from top to bottom. Its maximum outer diameter (i.e., the diameter of the bottom end of the arc-shaped plate) is 1.5m and the maximum inner diameter (i.e., the diameter of the top end of the arc-shaped plate) is 1.25m. In this embodiment, four expansion ramming plates 2 are arranged, each of which is matched with the main ramming plate. The inner wall of the expansion ramming plate can fit tightly with the outer wall of the main ramming plate. The four expansion ramming plates are evenly distributed and fit tightly on the outer wall of the main ramming plate.

Further, as shown in (a), (b) and (c) of Figure 3, the expansion tamping plate 2 is provided with a plurality of bolt holes 5, and the outer wall of the main tamping plate 1 is also provided with a plurality of bolt holes, and the main tamping plate and the expansion tamping plate are connected by detachable bolts. In addition, the expansion tamping plate and the main tamping plate have the same height, and when the expansion tamping plate and the main tamping plate are fixedly connected, the tamping hammer of the compacting machine is the main tamping plate + expansion tamping plate with a diameter of 1.5m.

As shown in Figure 2, the hydraulic connecting rod 3 corresponds to the expansion ramming plate 2 one by one. In this embodiment, four hydraulic connecting rods 3 are set. The hydraulic connecting rod 3 is set on the outside of the outer protective shell 6 of the tamping machine, and is connected to the corresponding expansion ramming plate through a lifting ring and an iron chain on the lifting ring. The hydraulic connecting rod 3 is electrically connected to the tamping machine controller and is used to pull the corresponding linked expansion ramming plate according to the control signal. Specifically, one end of the hydraulic connecting rod 3 is fixed to the outside of the outer protective shell 6 of the tamping machine, and the other end is connected to the expansion ramming plate 2 through an iron chain, and the side of the hydraulic connecting rod close to the expansion ramming plate is also fixedly connected to the outer protective shell of the tamping machine through a support rod; each expansion ramming plate is provided with a lifting ring 4 on both sides, and the lifting ring 4 is connected to one end of the iron chain, and the other end of the iron chain is fixedly connected to the end of the hydraulic connecting rod 3. The expansion ramming plate is pulled upward to the specified position by the hydraulic connecting rod, so that the main ramming plate and the expansion ramming plate are separated. At this time, the ramming hammer of the tamping machine is the main ramming plate with a diameter of 1.25m.

Furthermore, in this embodiment, the rammer of the compacting machine is composed of a main rammer plate with a diameter of 1.25m and four expansion rammer plates. The main rammer plate is connected to the upper compacting machine through a lifting ring and an iron chain on the lifting ring. The main rammer plate with a diameter of 1.25m and the four expansion rammer plates are connected by detachable bolts. When a high-speed hydraulic compacting machine is used in the reconstruction and expansion of a highway, if a rammer with a diameter of 1.5m is needed, the main rammer plate with a diameter of 1.25m and the four expansion rammer plates arranged evenly are fixed and connected with bolts, and then it can be used normally; if a rammer with a diameter of 1.25m is needed, the fixing bolts are first removed to separate the main rammer plate with a diameter of 1.25m and the four expansion rammer plates, and then the hydraulic connecting rod is controlled to pull the four expansion rammer plates upward to the specified position. At this time, the rammer size of the compacting machine is 1.25m in diameter.

Furthermore, the hydraulic connecting rod 3 pulls up the expansion ramming plate 2. In order to prevent the expansion ramming plate from shaking in the horizontal and vertical directions due to the huge vibration load generated during the operation of the ramming machine, which may affect the safety performance of the ramming machine, the ramming hammer of the ramming machine proposed in this embodiment also includes a baffle structure corresponding to the hydraulic connecting rod and the expansion ramming plate, respectively. The baffle structure is arranged at the bottom of the outer protective shell of the ramming machine, including a baffle 7 and a spring 8. Specifically, the baffle 7 is a structure with an L-shaped cross-section welded by a fan-shaped steel plate and a curved steel plate, which is used to fix the expansion ramming plate that is disassembled and lifted, and the curved steel plate is welded perpendicular to the fan-shaped steel plate; a plurality of grooves are arranged at the bottom of the outer protective shell 6 of the ramming machine, and the grooves correspond to the baffle structure one by one. The fan-shaped steel plate of the baffle is located inside the groove, and the curved steel plate of the baffle is located outside the groove. The end of the fan-shaped steel plate is connected to the outer protective shell of the ramming machine through a spring 8. When the spring contracts, the fan-shaped steel plate is inside the groove, and when the spring is extended, the fan-shaped steel plate extends out of the groove.

Among them, the setting of the baffle structure is determined according to the position of the hydraulic connecting rod, the maximum moving range of the hydraulic connecting rod and the height of the expansion ramming plate. It can ensure that when the hydraulic connecting rod pulls up the expansion ramming plate with the maximum moving range, the baffle pops out and just touches the bottom of the expansion ramming plate, thereby preventing the movement of the expansion ramming plate.

As another embodiment, as shown in FIG4 , a bayonet 9 is further provided on the bottom surface of the baffle plate, and an elastic buckle 10 is provided on the bottom surface of the groove. The bayonet 9 and the elastic buckle 10 cooperate to prevent the baffle plate from popping out of the groove when the spring is extended and retracted. That is, when the baffle plate is not needed to fix the expansion ramming plate, the elastic buckle 10 is controlled to pop out and clamp the fan-shaped steel plate. At this time, the spring 8 shrinks and the baffle plate 7 shrinks into the protective shell of the tamping machine; as shown in FIG5 , when the four expansion ramming plates are pulled to the maximum movement range of the hydraulic connecting rod by the hydraulic connecting rod 3, the elastic buckle 10 is controlled to be retracted (the buckle is not shown in FIG5 ), the compressed spring 8 is extended, and the baffle plate 7 pops out. At this time, the baffle plate 7 pops out from the bottom of the expansion ramming plate 2, and together with the iron chain, the four expansion ramming plates are fixed above the tamping machine, so as to avoid the problem that the expansion ramming plate shakes during the construction of the ramming machine and affects the safety performance of the tamping machine.

Furthermore, the spring buckle 10 is electrically connected to the compactor controller via wires, the wires are connected to the spring buckle along the outer protective shell of the compactor, the popping out and retraction of the buckle are controlled by the compactor operating room, and the electrical signal is transmitted through the wires.

As another implementation, when the baffle structure is not used, the baffle can be pushed back into the groove by manually pushing the baffle. In the process of pushing the baffle to move, the snap-in on the bottom of the baffle cooperates with the elastic snap-in at the elastic snap-in on the bottom of the groove to prevent the baffle from popping out. Furthermore, the end of the fan-shaped steel plate is also connected to the motor in the outer protective shell of the compactor through a steel wire rope, and the motor is electrically connected to the compactor controller. By controlling the operation of the motor, the steel wire rope is tightened, and then the baffle is pulled back into the groove until the baffle is stuck through the snap-in and the elastic snap-in, avoiding the problem of time-consuming and labor-intensive manual pushing.

The specific working process of the utility model is as follows:

When a high-speed hydraulic compactor is used in the reconstruction and expansion of a highway, when a 1.5m diameter compactor is needed, the 1.25m diameter main compactor plate 1 is fixedly connected to the four evenly arranged expansion compactors 2 with bolts. At this time, the compactor plate can be used normally, and no baffle is needed to fix the expansion compactor plate. During the hydraulic compaction process, the main compactor plate 1 is located directly below the main compactor hammer 11, and there is a distance between the bottom surface of the main compactor hammer 11 and the top surface of the main compactor plate 1 (the distance is greater than 0 and less than the length of the iron chain connecting the outer protective shell of the compactor and the main compactor plate). The lower bottom surface of the main compactor plate 1 is in contact with the ground at the compaction point, and the main compactor hammer 11 is driven by the hydraulic cylinder to hit the main compactor plate 1, thereby completing the compaction operation.

When a 1.25m diameter rammer is needed, first remove the fixing bolts to separate the 1.25m diameter main rammer plate 1 and the four extended rammer plates 2, then control the hydraulic connecting rod 3 to pull the four extended rammer plates 2 upward to the specified position (i.e. pull to the maximum movement range of the hydraulic connecting rod), then control the elastic buckle 10 to retract, the compressed spring 8 to extend, the baffle 7 to pop out from under the extended rammer plate 2, and fix the four extended rammer plates 2 above the rammer together with the iron chain to avoid the extended rammer plates shaking during the construction of the rammer and affecting the safety performance of the rammer. At this time, the rammer size of the rammer is 1.25m in diameter and can be used normally.

Embodiment 2

This embodiment proposes a high-speed hydraulic rammer, including the easily replaceable rammer hammer proposed in the first embodiment.

The easily replaceable rammer hammer and high-speed hydraulic rammer proposed in the utility model have the function of convenient switching between two sizes of rammers with a diameter of 1.25m and 1.5m. There is no need to transport two sizes of rammers at the same time, which saves manpower and material resources during transportation. At the same time, when two sizes of rammer plates need to be replaced during construction, they can be easily replaced, which also avoids the situation where the high-speed hydraulic rammer is moved unnecessary to replace the rammer plates, resulting in poor tamping effect. In addition, the utility model is also equipped with baffles, hydraulic connecting rods and other facilities, which greatly improves the safety factor of the equipment during operation.

Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the protection scope of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the protection scope of the utility model.
