Description

Technical Field

[0001] This invention relates to the field of dam construction equipment technology, and in particular to a device for pressing and forming a slope protection layer for hydraulic dams. Background Technology

[0002] During the construction and reinforcement of water conservancy dams, the slope protection layer of the dam usually needs to be continuously formed to improve the overall stability of the dam surface, its erosion resistance, and its subsequent reliability. Especially during the construction of the upstream slope, downstream slope, or slope protection structure of the dam, the protection layer often needs to be pressed and shaped along the slope direction after construction to make its surface thickness distribution more uniform, the layer more stable in contact with the base layer, and reduce problems such as local unevenness, looseness and hollowness, and poor connection in the transition area.

[0003] Existing equipment is not adaptable to different slopes and working heights when working across slopes. Especially when the slope span is large, it is inconvenient to adjust the overall posture of the equipment, and it is difficult to maintain a stable fit between the working components and the slope. This can easily affect the quality of the protective layer. When treating the slope protective layer, most of the time only local operations can be carried out on a single area. There is a lack of effective supplementary covering structures for the middle transition zone between the left and right working areas. This can easily lead to problems such as insufficient covering in the transition area, obvious surface height difference, and poor continuity, which in turn affect the construction quality and structural stability of the entire dam protective layer.

[0004] Therefore, it is necessary to invent a device for pressing and molding the slope protection layer of water conservancy dams to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a device for pressing and molding the slope protection layer of a hydraulic dam to solve the problems mentioned in the background art.

The inclined main guide rail assembly includes a main guide rail beam and end guide rail beams. A traction chain is provided inside the main guide rail beam, and a traction motor that is driven and connected to the traction chain is provided on the main guide rail beam. The middle moving work frame is driven and connected to the traction chain to slide along the inclined main guide rail assembly. Each of the two end guide rail beams is provided with an end connecting frame, and a sliding sleeve is connected to the outside of the end connecting frame. The sliding sleeve cooperates with the end lifting support assembly to realize the connection between the inclined main guide rail assembly and the end lifting support assembly. The end lifting support assembly includes a walking base and a support column disposed on the walking base, and the sliding sleeve is slidably sleeved on the support column; The pressing plate assembly has two sets symmetrically arranged on the left and right, and the middle plate pressing plate assembly is arranged between the two sets of pressing plate assemblies; The pressing plate assembly and the middle plate pressing assembly each have an independent adjustment structure, so that when the pressing plate assembly is in the working position, the middle plate pressing assembly rises to the clearance position; when the middle plate pressing assembly is in the working position, the pressing plate assembly is raised to the clearance position.

[0007] Preferably, an adaptive connector is provided between the end connecting frame and the main guide beam, and the end connecting frame and the sliding sleeve are connected by a pin hinge, so that the inclined main guide rail assembly can adaptively adjust its attitude relative to the end lifting support assembly.

[0008] Preferably, the central moving work frame includes a sliding guide frame and guide rollers disposed on the sliding guide frame. The sliding guide frame is connected to the traction chain, and the guide rollers are in rolling cooperation with the main guide beam to guide the central moving work frame to slide stably along the inclined main guide assembly.

[0009] Preferably, each of the pressing disc assemblies includes a disc mounting base located outside the sliding guide frame, a floating guide frame fixedly mounted on the upper surface of the disc mounting base, a connecting arm mounted between the floating guide frame and the sliding guide frame, a first drive motor fixedly mounted above the disc mounting base, and a pressing disc mounted on the output shaft of the first drive motor. The pressing disc is a disc-shaped structure with an upward curve around its perimeter.

[0010] Preferably, each pressing plate assembly has two connecting arms, which are arranged in parallel and hinged to the sliding guide frame and the floating guide frame to form a parallelogram swing structure, so as to drive the pressing plate assembly to swing and adjust relative to the central moving work frame.

[0011] Preferably, the pressing disc assembly further includes a transmission rod, a winch, and a traction rope. The winch is fixedly installed on the top of the sliding guide frame and drives the connecting arm to move through the traction rope and the transmission rod, so as to adjust the swing posture and working position of the pressing disc assembly.

[0012] Preferably, the middle plate pressing assembly includes a mounting base, a pressing plate, a vibration motor, a movable plate, a support base, a lead screw sleeve, a lead screw, and a second drive motor. The support base is fixedly disposed inside the sliding guide frame. The movable plate is located below the support base. The lead screw is fixedly disposed on the upper surface of the movable plate. The lead screw sleeve is sleeved and fitted onto the lead screw, and the lead screw sleeve is mounted in the middle of the support base via a bearing. The second drive motor is mounted above the support base and is used to drive the lead screw sleeve to rotate, thereby driving the movable plate to rise and fall. The mounting base is located below the movable plate. The pressing plate is fixedly mounted below the mounting base. The vibration motor is fixedly mounted on the pressing plate.

[0013] Preferably, the pressing plate is disposed at the corresponding position of the transition area formed between the two pressing plate assemblies, and is used to supplement the pressing of the protective layer transition area between the two pressing plate assemblies. Both ends of the pressing plate are set as arc-shaped upward curved structures.

[0014] Preferably, the mounting base and the support are connected by multiple shock absorbers to reduce the transmission of vibration from the pressure plate to the support and sliding guide frame.

[0015] Preferably, an electric hoist is fixedly installed at the top of the supporting column, and the moving end of the electric hoist is connected to the top of the end connecting frame.

[0016] The technical effects and advantages of this invention are as follows: 1. This invention, by setting up an inclined main rail assembly, an end lifting support assembly, and a central moving work frame, enables the entire machine to operate across both ends of the inclined surface of a hydraulic dam. Furthermore, through the cooperation between the end connecting frame, adaptive connector, sliding sleeve, and support column, the inclined main rail assembly can adapt to posture adjustments under different slope and height conditions, improving the equipment's adaptability in dam slope construction scenarios. At the same time, the traction chain and traction motor work together to drive the central moving work frame to move along the inclined main rail assembly, enabling the equipment to achieve continuous and stable construction along the dam slope, which is beneficial to improving the operational efficiency of long-distance revetment layer construction.

[0017] 2. This invention sets up two symmetrical pressing disc assemblies on a central movable working frame, and uses connecting arms to form a parallelogram swing structure. The working posture of the pressing disc assemblies is adjusted using a winch, traction rope, and transmission rod, allowing the pressing discs to better adapt to the construction needs of the main areas on both sides of the sloping revetment layer. This improves the pressing and shaping capability of the main areas. Simultaneously, a central plate-type pressing assembly that can be independently raised and lowered is set between the two pressing disc assemblies. The pressing plate supplements the pressing of the transition area between the two discs, effectively reducing under-pressing, height differences, and discontinuous transitions at the junction of the two discs. This improves the consistency and continuity of the overall pressing and shaping of the dam's sloping revetment layer.

[0018] 3. This invention incorporates a vibration motor, movable plate, lead screw sleeve, lead screw, drive motor, and shock absorber in the central plate pressing assembly. This allows the pressing plate to have independent lifting and positioning functions, as well as the ability to vibrate and press the central transition area. This not only improves the compaction effect of the transition area but also reduces the transmission of vibration to the support base and sliding guide frame. Combined with the arc-shaped upward-curving structure at both ends of the pressing plate and the upward-curving disc-shaped structure around the pressing plate, it reduces the obstruction and local cutting into the surface of the protective layer during operation, thereby improving the overall operational stability of the equipment and the forming quality of the protective layer.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 9 As shown, the hydraulic dam slope protection layer pressing and forming device provided by the present invention is essentially a hydraulic dam construction device that can solve the problems of insufficient adaptability of existing slope protection layer construction equipment to cross-slope support, difficulty in simultaneously covering the main area and the middle transition zone, and poor consistency of overall slope protection layer pressing and forming.

[0031] In terms of specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment. In this embodiment, no special limitations are imposed.

[0032] In this embodiment, a hydraulic dam slope protection layer pressing and forming device includes an inclined main rail assembly 1, end lifting support assemblies 2 disposed at both ends of the inclined main rail assembly 1, a central moving work frame 3 disposed on the inclined main rail assembly 1, a pressing plate assembly 4 disposed on the central moving work frame 3, and a central plate pressing assembly 5.

[0033] The inclined main guide rail assembly 1 includes a main guide rail beam 11 and end guide rail beams 12 respectively disposed at both ends of the main guide rail beam 11. The main guide rail beam 11 adopts a truss beam structure to provide the main support length for the entire machine spanning the inclined surface of the embankment. The end guide rail beams 12 are fixedly connected to both ends of the main guide rail beam 11 for connection and support with the end lifting support assembly 2. A traction chain 111 is disposed inside the main guide rail beam 11, and a traction motor 112 is disposed on the main guide rail beam 11 and is drivenly connected to the traction chain 111. The traction motor 112 is preferably a geared motor, and its output end cooperates with the traction chain 111 through a sprocket to drive the central moving work frame. 3. The inclined main rail assembly 1 moves back and forth. The ends of the two end guide rail beams 12 are respectively provided with end connecting frames 13. The end connecting frames 13 can be formed by profile welding frame structure and are used as transition connecting parts between the inclined main rail assembly 1 and the end lifting support assembly 2. An adaptive connector 131 is provided between the end connecting frame 13 and the main rail beam 11. The adaptive connector 131 can preferably be a connection structure with elastic compensation capability, a universal connection structure or a swing connection structure, so that the inclined main rail assembly 1 can adaptively adjust its attitude relative to the end lifting support assembly 2 under different slope ratios and different construction heights. The outer side of the end connecting frame 13 is connected to a sliding sleeve 14. The sliding sleeve 14 is preferably a sleeve-type sliding component. Its inner cavity is adapted to the outer contour of the support column 22. The end connecting frame 13 and the sliding sleeve 14 are connected by a pin hinge, so that the inclined main guide rail assembly 1 can synchronously generate angle adaptation changes when the height is adjusted.

[0034] The end lifting support assembly 2 includes a traveling base 21 and a support column 22 mounted on the traveling base 21. The traveling base 21 can be configured as a wheeled base, a tracked base, or a rail base according to the construction site conditions, to form stable support at the top or bottom platform of the dam slope. The support column 22 is fixedly installed on the traveling base 21, preferably using a rectangular column, a round tube column, or a box-type column structure to improve the vertical bearing capacity. The sliding sleeve 14 is slidably mounted on the support column 22, so that the inclined main rail assembly 1 can be adjusted up and down along the support column 22. An electric hoist 23 is fixedly mounted on the top of the support column 22, and its moving end is connected to the top of the end connecting frame 13 for lifting and adjusting the end connecting frame 13, thereby assisting in the lifting and adjustment of the end of the inclined main rail assembly 1. Through the cooperation of the electric hoist 23 and the sliding sleeve 14, the difficulty of manual adjustment can be reduced, and the adjustment efficiency and stability of the whole machine during the construction layout on the dam slope can be improved.

[0035] The central moving work frame 3 is mounted on the inclined main rail assembly 1 and is used to support the pressing plate assembly 4 and the central plate pressing assembly 5. The central moving work frame 3 includes a sliding guide frame 31 and guide rollers 32 mounted on the sliding guide frame 31. The sliding guide frame 31 preferably adopts a frame-type load-bearing structure for installing various working components and connecting with the traction chain 111. The guide rollers 32 roll in cooperation with the main rail beam 11, so that the sliding guide frame 31 can slide smoothly along the main rail beam 11, reducing running resistance. The sliding guide frame 31 is connected to the traction chain 111 and moves along the inclined main rail assembly 1 under the drive of the traction motor 112 to realize continuous operation of the whole machine along the length of the dam slope.

[0036] The pressing plate assembly 4 has two sets of left and right symmetrical sets. Each pressing plate assembly 4 includes a plate mounting base 41 located outside the sliding guide frame 31, a floating guide frame 42 fixedly installed on the upper surface of the plate mounting base 41, a connecting arm 43 installed between the floating guide frame 42 and the sliding guide frame 31, a first drive motor 411 fixedly installed above the plate mounting base 41, and a pressing plate 412 installed on the output shaft of the first drive motor 411. The plate mounting base 41 is used to support the first drive motor 411 and the pressing plate 412. The floating guide frame 42 is used to provide the swing guide base for the pressing plate assembly 4. Each pressing plate assembly 4 has two connecting arms 43. The two connecting arms 43 are arranged in parallel and hinged with the sliding guide frame 31 and the floating guide frame 42 to form a parallelogram swing structure to drive the pressing plate assembly 4 to swing and adjust relative to the central moving work frame 3. The pressing plate assembly 4 also includes a transmission rod 431, a winch 432, and a traction rope 433. The winch 432 is fixedly installed on the top of the sliding guide frame 31 and drives the connecting arm 43 to move through the traction rope 433 and the transmission rod 431 to adjust the swing posture and working position of the pressing plate assembly 4. The pressing plate 412 is a disc-shaped structure with an upward curve around the perimeter to reduce the tendency of the edge to cut into the protective layer during the pressing process, so that it can press the protective layer of the embankment slope more smoothly.

[0037] The middle plate pressing assembly 5 is located between the two pressing disc assemblies 4 and is used to supplement the pressing of the middle transition area formed between the left and right pressing disc assemblies 4. The middle plate pressing assembly 5 includes a mounting base 51, a pressing plate 52, a vibration motor 53, a movable plate 54, a support base 55, a lead screw sleeve 551, a lead screw 552, and a second drive motor 553. The support base 55 is fixedly installed inside the sliding guide frame 31. The movable plate 54 is located below the support base 55. The lead screw 552 is fixedly installed on the upper surface of the movable plate 54. The lead screw sleeve 551 is sleeved and fitted onto the lead screw 552, and the lead screw sleeve 551 is installed in the middle of the support base 55 via a bearing. The second drive motor 553 is installed above the support base 55 and is used to drive the lead screw 552. The sleeve 551 rotates to drive the movable plate 54 to rise and fall. The mounting base 51 is fixedly located below the movable plate 54. The pressing plate 52 is fixedly installed below the mounting base 51. The vibration motor 53 is fixedly installed on the pressing plate 52 and is used to provide vibration pressing action on the pressing plate 52 when the middle plate pressing assembly 5 is in the working position. The pressing plate 52 is set at the corresponding position of the transition area formed between the two pressing plate assemblies 4. Both ends of the pressing plate 52 are set with arc-shaped upward curved structure to reduce the scratch resistance of the pressing plate 52 on the surface of the protective layer during the lifting and pressing process. The mounting base 51 and the support base 55 are connected by multiple shock absorbers 541 to reduce the transmission of the working vibration of the pressing plate 52 to the support base 55 and the sliding guide frame 31.

[0038] In this embodiment, the pressing disc assembly 4 and the middle plate pressing assembly 5 each have an independent adjustment structure, and the two are not in the working position at the same time. When the pressing disc assembly 4 is in the working position, the middle plate pressing assembly 5 rises to the avoidance position under the action of the second drive motor 553 to avoid interference with the pressing areas on both sides. When the middle plate pressing assembly 5 is in the working position, the winch 432 drives the pressing disc assembly 4 to be lifted to the avoidance position through the traction rope 433 and the transmission rod 431, thereby ensuring the independent supplementary pressing operation of the middle transition area.

[0039] In this embodiment, when the equipment is in use, the two end lifting support components 2 are first arranged at the upper and lower ends of the slope of the water conservancy dam, respectively. The initial positioning is completed by the walking base 21. Then, the electric hoist 23 at the top of the support column 22 is used to lift the end connecting frame 13, so that the sliding sleeve 14 slides up and down along the support column 22, thereby adjusting the inclined main rail component 1 to the installation height and tilt angle adapted to the slope of the dam. During the adjustment process, the pin connection between the end connecting frame 13 and the sliding sleeve 14 and the adaptive connector 131 between the end connecting frame 13 and the main rail beam 11 work together to enable the inclined main rail component 1 to adaptively adjust its posture according to the slope ratio of the dam and the on-site installation status until the whole machine is stable. After the equipment is set up, start the traction motor 112. The traction motor 112 drives the central moving work frame 3 to slide along the direction of the main guide beam 11 through the traction chain 111. The guide roller 32 rolls with the main guide beam 11 to guide and support the sliding guide frame 31, so that the central moving work frame 3 can move smoothly along the length of the dam slope. When it is necessary to carry out the cladding construction on both sides of the main area of ​​the slope protection layer of the embankment, the central plate cladding assembly 5 is controlled to be in the avoidance position. Then, the winch 432 is started, and the connecting arm 43 is driven by the traction rope 433 and the transmission rod 431 to move, so that the left and right cladding plate assemblies 4 swing to the working position. At this time, the two sets of cladding plates 412 rotate under the drive of the first drive motor 411 and press against the main areas on the left and right sides of the slope protection layer of the embankment to cladding and shape the protection layer. Since each set of cladding plate assemblies 4 forms a parallelogram swing structure through two parallel connecting arms 43, the cladding plate 412 can maintain a relatively stable posture during the adjustment process, which is conducive to adapting to the local undulations of the slope protection layer and improving the continuity and uniformity of the cladding area. When additional pressing is required in the intermediate transition area between the two pressing plate assemblies 4, the winch 432 is first controlled to lift the left and right pressing plate assemblies 4 to the clearance position via the traction rope 433 and transmission rod 431. Then, the second drive motor 553 is started, causing the lead screw sleeve 551 to rotate and cooperate with the lead screw 552 fixed on the movable plate 54, thereby driving the movable plate 54, the mounting base 51 and the pressing plate 52 to descend to the working position. After the pressing plate 52 reaches the working position, the vibration motor 53 is started, so that the pressing plate 52 performs additional pressing on the intermediate transition area under its own weight and vibration. Since the two ends of the pressing plate 52 are set with an arc-shaped upward structure, it can reduce the obstruction and scratching of the surface of the protective layer during its movement along the construction direction. At the same time, the shock absorber 541 isolates the working vibration generated by the vibration motor 53, reducing the transmission of vibration to the support seat 55 and the sliding guide frame 31, ensuring the smooth operation of the whole machine.

[0040] During construction, the left and right pressure plate assemblies 4 and the middle plate pressure assembly 5 can alternately switch between working positions and avoidance positions according to actual working conditions. When the width of the slope protection layer of the dam is large and the main area needs to be covered first, the left and right covering plate assemblies 4 should be prioritized for operation. When the main area is covered and the middle transition zone needs to be treated, the middle plate-type covering assembly 5 is lowered to the working position for supplementary covering. Through the above alternating working method, the main area and transition zone of the dam slope protection layer can be covered separately without increasing the overall structural complexity of the machine, thereby improving the consistency, continuity and stability of the overall covering layer.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
