Description

Technical Field

[0001] This utility model belongs to the field of dam construction technology, and relates to compaction devices for construction, particularly a compaction device for filling construction of pumped storage power station dams. Background Technology

[0002] Pumped storage power stations, as important peak-shaving, valley-filling, and energy storage facilities in the power system, have dams whose stability and safety directly affect the station's operational efficiency and service life. The quality of dam filling construction is a key factor in ensuring dam stability, and compaction, as a core procedure in dam filling construction, plays a decisive role in improving dam density, enhancing impermeability, and increasing load-bearing capacity.

[0003] Traditional dam construction and compaction methods typically involve using both large and small compactors. However, using the small compactor presents two problems: First, workers need to hold the handles to control it, but due to the continuous vibration of the compactor, prolonged support can easily cause numbness and soreness in the workers' arms. Second, when moving the compactor over short distances, workers need to carry it, which greatly increases their physical exertion. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a compaction device for the filling construction of pumped storage power station dams. The technical problem to be solved by this utility model is: how to make the compaction device easy for workers to use and move.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A compaction device for dam filling construction in a pumped storage power station includes a U-shaped base plate. A U-shaped frame is fixedly connected to the middle of the U-shaped base plate. Two sliding rods are fixedly connected between the top and bottom of the inner side of the U-shaped frame. A fixing block is slidably fitted onto the circumferential surface of each sliding rod. Both fixing blocks have circular holes adapted to the sliding rods. A common compaction machine body is fixedly connected to one side of the two fixing blocks. Both sides of the outer wall of the compaction machine body are fixedly connected with protruding rods. A lifting mechanism is provided at the top of the U-shaped base plate. The lifting mechanism includes components located at the top of the U-shaped base plate on both sides of the compaction machine body. The moving plates have beveled edges near the protruding rods. U-shaped plates are fixedly connected to the opposite sides of the two moving plates. Two guide rods are fixedly connected inside each U-shaped plate. The same slider is slidably fitted on the circumferential surface of the two guide rods on the same side. The two sliders have circular holes that match the guide rods. The two sliders are fixedly connected to the top of the U-shaped base plate. The lifting mechanism also includes L-shaped plates fixedly connected to the top of the moving plates on the side away from the compactor body. The same stop rod is fixedly connected between the top ends of the two L-shaped plates.

[0007] The working principle of this utility model is as follows: by setting up the sliding rod, the U-shaped frame and the fixing block, the vibration intensity of the compactor body will not be fully transmitted to the U-shaped push handle when compacting, which makes it easy for workers to use and will not cause arm pain. At the same time, it is easy to lift the compactor body, so that when the section is transferred, there is no need for workers to carry it.

[0008] The top of the U-shaped base plate, away from the compactor body, is fixedly connected to two side plates on both sides. The bottom of the two side plates is rotatably connected to the same connecting rod, and the two ends of the connecting rod are fixedly connected to the same U-shaped push handle. The U-shaped push handle is adapted to the stop bar. Rectangular holes are opened on both sides of the U-shaped push handle. A rectangular block is slidably installed in each rectangular hole. A limit rod is fixedly connected between the top and bottom of each rectangular hole. Each limit rod slides through the adjacent rectangular block. A round hole adapted to the limit rod is opened on each rectangular block.

[0009] With the above structure, the height of the U-shaped push handle can be adjusted by rotating it, making it convenient for different workers to use. It also facilitates the squeezing of the stop bar, which drives the lifting mechanism and raises the compactor body.

[0010] Each of the limiting rods is fitted with a spring at the top, and the bottom outer sides of the two rectangular blocks are fixedly connected with a locking block. The two rectangular blocks are fixedly connected to the same U-shaped rod on the side that is close to each other.

[0011] With the above structure and the spring, the locking block is always engaged with the slot when no external force is applied. By pulling the U-shaped rod, the spring can be compressed, causing the locking block to separate from the slot.

[0012] Both side plates have arc-shaped holes in the middle, and the arc-shaped holes are concentric with the connecting rod. Each arc-shaped hole has multiple slots on the side closest to the connecting rod, and the slots are adapted to the locking blocks. Wheels are provided at the four corners of the bottom of the U-shaped base plate.

[0013] By adopting the above structure, the combination of arc-shaped holes and slot blocks allows the blocks to be locked in different slots, thereby achieving the fixation of the U-shaped push handle in different positions.

[0014] Compared with existing technologies, the compaction device for dam body filling construction of this utility model has the following advantages:

[0015] 1. In this utility model, by employing a lifting mechanism, a U-shaped frame, a sliding rod, and the compactor body, the vibration of the compactor body is partially blocked through the cooperation of the sliding rod and the fixing block, thus reducing the vibration intensity at the U-shaped push handle and facilitating its use by the operator. The lifting mechanism allows the compactor body to be lifted, and the operator can move it using the wheels, facilitating its transfer. This effectively solves the problems of inconvenient transfer and easy numbness of the operator's arms during operation mentioned in the background art, thereby reducing the vibration force borne by the operator's arms during operation and effectively avoiding problems such as arm numbness and fatigue. At the same time, the lifting mechanism can easily lift the compactor body, and with the wheels, it can achieve flexible movement, solving the problems of traditional compaction equipment being bulky and difficult to transfer.

[0016] 2. In this utility model, the U-shaped push handle rectangular block limiting rod, locking block, locking groove and arc hole are designed to facilitate the adjustment of the height of the U-shaped push handle, thereby improving the working posture of the staff and making it easier for staff of different heights to use, thus improving adaptability.

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figures 1-6 As shown, a compaction device for dam filling construction of a pumped storage power station includes a U-shaped base plate 1. A U-shaped frame 4 is fixedly connected to the middle of the U-shaped base plate 1. Two sliding rods 401 are fixedly connected between the top and bottom of the inner side of the U-shaped frame 4. Each sliding rod 401 has a fixing block 202 slidably fitted on its circumferential surface. Both fixing blocks 202 have round holes adapted to the sliding rods 401. The same compaction machine body 2 is fixedly connected to one side of the two fixing blocks 202. Both sides of the outer wall of the compaction machine body 2 are fixedly connected with protruding rods 201. A lifting mechanism 5 is provided at the top of the U-shaped base plate 1. Mechanism 5 includes movable plates 501 located on the top of the U-shaped base plate 1 on both sides of the compactor body 2. Each movable plate 501 has a bevel 502 near the protruding rod 201. A U-shaped plate 505 is fixedly connected to the side of each movable plate 501 that is far apart from each other. Two guide rods 506 are fixedly connected inside each U-shaped plate 505. The same slider 507 is slidably fitted on the circumferential surface of the two guide rods 506 on the same side. Both sliders 507 have round holes that are adapted to the guide rods 506, and both sliders 507 are fixedly connected to the top of the U-shaped base plate 1.

[0026] In this utility model, the lifting mechanism 5 also includes an L-shaped plate 503 that is fixedly connected to the top of the moving plate 501 on the side away from the compactor body 2. The top ends of the two L-shaped plates 503 are fixedly connected to the same stop bar 504. With the setting of the lifting mechanism 5, when the U-shaped push handle 601 presses the stop bar 504, the two moving plates 501 can lift the protruding rod 201, thereby lifting the compactor body 2 for easy transfer.

[0027] In this utility model, the top of the U-shaped base plate 1, away from the compactor body 2, is fixedly connected to two side plates 3 on both sides. The bottom of the two side plates 3 is rotatably connected to the same connecting rod 6, and the two ends of the connecting rod 6 are fixedly connected to the same U-shaped push handle 601. The U-shaped push handle 601 is adapted to the stop rod 504. Rectangular holes 602 are opened on both sides of the U-shaped push handle 601. A rectangular block 604 is slidably installed in each rectangular hole 602. A limit rod 605 is fixedly connected between the top and bottom of each rectangular hole 602. Each limit rod 605 slides through the adjacent rectangular block 604. A round hole adapted to the limit rod 605 is opened on each rectangular block 604.

[0028] In this utility model, a spring 606 is sleeved at the top of each limiting rod 605, and a locking block 607 is fixedly connected to the bottom of the outer side of each of the two rectangular blocks 604. The same U-shaped rod 603 is fixedly connected to the side of the two rectangular blocks 604 that are close to each other.

[0029] In this utility model, an arc-shaped hole 301 is provided in the middle of both side plates 3, and the arc-shaped hole 301 is concentric with the connecting rod 6. Each arc-shaped hole 301 has multiple slots 302 on the side near the connecting rod 6, and the slots 302 are adapted to the locking block 607. Through the cooperation of the locking block 607 and the slots 302, the height of the U-shaped push handle 601 can be easily controlled, making it convenient to use.

[0030] In this utility model, wheels 101 are provided at the four corners of the bottom of the U-shaped base plate 1. The two wheels 101 closest to the compactor body 2 are rotatably connected to the U-shaped base plate 1, which facilitates direction control.

[0031] The working principle of this utility model is as follows: When the device is powered on, the compactor body 2 is started. The operator controls the compactor body 2 by holding the U-shaped push handle 601, so that the compactor body 2 compacts the material at the required location. The two wheels 101 near the compactor body 2 are rotatably connected to the U-shaped base plate 1, which facilitates the control of the compactor body 2. When the compactor body 2 is compacting, the setting of the sliding rod 401 and the fixed block 202 allows the compactor body 2 to slide along the sliding rod 401 via the fixed block 202. This prevents the operator's arm from vibrating due to the vibration of the compactor body 2. The U-shaped frame 4 and the sliding rod 401 can alleviate the operator's arm pain and improve practicality. At the same time, it can be adapted to the operator's usage habits and different heights. Pulling the U-shaped rod 603 causes the two rectangular blocks 604 to compress the spring 606, and the locking block 607 to separate from the locking groove 302. Then, pushing the U-shaped push handle 601 adjusts its position for easy use by the operator. When the compactor body 2 needs to be moved, the top of the U-shaped push handle 601 can be pushed towards one side of the compactor body 2, causing the U-shaped push handle 601 to press against the stop bar 504, which causes the two moving plates 501 to move towards one side of the compactor body 2. With the inclined side 502, the two moving plates 501 are inserted into the bottom of the protruding rod 201. By raising the two protruding rods 201, the compactor body 2 is lifted. Then, fixing the U-shaped push handle 601 allows for rapid movement of the compactor body 2 without manual handling, as it can be moved quickly using the wheels 101.

[0032] In summary, in this utility model, by setting up the sliding rod 401 and the fixing block 202, the vibration of the compactor body 2 is not entirely transmitted to the U-shaped base plate 1 and the U-shaped push handle 601. When the staff of Shudie hold the U-shaped push handle 601, they will not experience arm pain due to excessive vibration, thus improving practicality. At the same time, it is easy to adjust the height of the U-shaped push handle 601, further improving practicality. In addition, through the cooperation of the U-shaped push handle 601 and the lifting mechanism 5, the compactor body 2 can be raised to a certain height, which facilitates the transfer of the compactor body 2 without the need for manual handling.
