Description

Technical Field

[0001] This utility model is a retaining device for dam construction, belonging to the field of retaining devices. Background Technology

[0002] In water conservancy projects, dam construction is a crucial foundational project. During dam construction, in order to prevent soil collapse and ensure construction safety and quality, retaining equipment is needed to effectively block and protect the soil in the construction area. Currently, most common dam construction retaining equipment adopts a fixed structure design. The retaining plates are usually installed on the base at a fixed angle. Some equipment will set simple fixed piles on the base to enhance stability, but the overall structure is relatively simple. The protective structure of such equipment is also relatively rudimentary. Most of them rely solely on the rigid material of the retaining plate to directly resist the soil pressure, lacking a dedicated buffer device.

[0003] Currently, the retaining plate angles of commonly available dam construction retaining equipment are fixed, making it difficult to adapt to changes in slope and construction needs. This results in poor equipment applicability, often requiring frequent replacement of different types of retaining equipment when facing diverse construction scenarios, increasing construction costs and difficulty. Furthermore, the performance of existing retaining equipment in terms of protection and buffering is unsatisfactory. When the soil slides or is impacted by external forces, the retaining equipment lacks an effective buffer structure, and the impact force of the soil acts directly on the retaining plate. This not only easily damages the retaining plate and shortens the service life of the equipment, but may also cause safety accidents, threatening the lives of construction workers. Therefore, it is necessary to design a new type of dam construction retaining equipment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a retaining device for dam construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a retaining device for dam construction, comprising a base plate, one end of which is provided with a shovel, and a retaining plate is hinged to the top of the base plate near the shovel.

The sprocket transmission mechanism includes a drive wheel connected to the drive assembly, two driven wheels arranged symmetrically on the left and right, and a transmission chain for driving the drive wheel and the driven wheels. The end of the lead screw is connected to the transmission wheel.

[0008] Furthermore, the upper surface of the protective buffer plate is concave, and rollers are evenly installed in the lower groove of the protective buffer plate, and the rollers are rotatably connected to the protective buffer plate.

A buffer spring is wound around the outside of the damper, and a baffle is rotatably connected to the bottom of the damper. A screw is integrally connected to the bottom of the baffle. Annular grooves are evenly spaced on the support rod, and the inner diameter of the annular groove matches the outer diameter of the screw. The bottom of the screw passes through the annular groove and is threadedly connected to the threaded sleeve.

[0010] Furthermore, the drive assembly includes a first bevel gear, a second bevel gear, and a rotating handle.

[0011] Furthermore, the cross-section of the movable block is designed in the shape of a cross, and the shape of the movable block matches the internal shape of the movable groove.

[0012] The beneficial effects of this utility model are as follows: In the complex and ever-changing environment of dam construction, the angle-adjustable retaining plate can be flexibly adjusted according to different terrains and construction stages, closely adhering to the soil, effectively preventing soil sliding and reducing the risk of collapse. At the same time, the buffer protection device can cope with sudden impacts such as large rocks and mud clods rolling down, absorbing and dispersing the impact force, avoiding the impact force from acting directly on the retaining plate and connecting parts, preventing equipment damage and structural instability.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1 to 5This utility model provides a technical solution: a retaining device for dam construction, including a base plate 1, a shovel 2 at one end of the base plate 1, and a retaining plate 3 hinged to the top of the base plate 1 near the shovel 2. Movable grooves 103 are provided on both sides of the top of the base plate 1, and movable blocks 14 are provided within the movable grooves 103. A connecting seat 9 is integrally provided on the top of the movable block 14, and a support rod 7 is hinged to the top of the connecting seat 9. Hinged seats 8 are bolted to both sides of the retaining plate 3 at the end away from the shovel 2, and the other end of the support rod 7 is hinged to the hinged seat 8. Buffer members 13 are evenly installed on the support rod 7, and the top of the buffer members 13 is connected to... The device has a protective buffer plate 4, a screw rod 12 rotatably connected in the movable groove 103, and a screw rod groove 1401 adapted to the screw rod 12 on the movable block 14. The setting of the shovel 2 allows the device to be quickly inserted into the ground for initial fixation. Together with the base plate 1, it enhances the stability of the device during construction. The combined design of the protective buffer plate 4 and the buffer component 13 forms a multi-layer protective buffer system. From changing the direction of the impacting object to absorbing and dispersing the impact energy, it can effectively resist the impact of soil, rocks, etc., reduce the probability of equipment damage, extend the service life of the equipment, and also reduce the construction interruption and maintenance costs caused by equipment damage. For example, ground nails 6 are inserted through the four corners of the base plate 1, and the outer surface of the ground nails 6 is provided with rotating threads. A slot 10 is provided on one side of the base plate 1, and an insert 5 adapted to the slot 10 is provided on the other side of the base plate 1. The design of the ground nails 6 and their rotating threads makes the equipment tightly connected to the ground. Compared with the traditional method of fixing only by the shovel 2 or simply by heavy load, it can better resist the lateral pressure of the soil and external impact, providing a solid guarantee for construction safety. The cooperation of the slot 10 and the insert 5 can be used to splice multiple base plates 1, expanding the application range of the retaining equipment.

[0016] For example, a transmission chamber 101 is provided at the end of the base plate 1 away from the shovel 2, and a drive chamber 102 is provided at the center of the transmission chamber 101. A drive assembly 11 is installed in the drive chamber 102, and a sprocket transmission mechanism 16 is provided in the transmission chamber 101. The sprocket transmission mechanism 16 includes a drive wheel connected to the drive assembly 11, two driven wheels arranged symmetrically on the left and right, and a transmission chain for driving the drive wheel and the driven wheels. The end of the lead screw 12 is connected to the drive wheel. The transmission chamber 101 and the drive chamber 102 provide good protection for the internal transmission components, effectively isolating impurities such as mud, dust, and rainwater in the construction environment, and reducing the erosion and wear of these factors on the transmission components.

[0017] Please see Figure 3The upper surface of the protective buffer plate 4 is concave, and rollers 401 are evenly installed in the concave groove of the protective buffer plate 4. The rollers 401 are rotatably connected to the protective buffer plate 4. The combination of the concave design and the rollers 401 can provide double buffering for rolling large rocks, large mud blocks and other heavy objects, change the trajectory of the object and reduce friction, effectively reducing the direct impact force of the object on the protective buffer plate 4. In conjunction with the buffer component 13, it greatly improves the equipment's ability to resist external impacts, provides reliable protection for the retaining plate 3 and the connecting structure, and ensures construction safety.

[0018] Please see Figure 4 The buffer component 13 includes a rotating component 1301, a damper 1302, a buffer spring 1303, a screw 1304, a baffle 1305, and a threaded sleeve 15. The rotating component 1301 is rotatably connected to the bottom of the protective buffer plate 4, and the damper 1302 is fixed to the bottom of the rotating component 1301. The buffer spring 1303 is wound around the outside of the damper 1302, and the baffle 1305 is rotatably connected to the bottom of the damper 1302. The screw 1304 is integrally connected to the bottom of the baffle 1305. Annular grooves 701 are evenly spaced on the support rod 7, and the annular grooves 701... The inner diameter matches the outer diameter of the screw 1304. The bottom of the screw 1304 passes through the annular groove 701 and is threadedly connected to the threaded sleeve 15. When the protective buffer plate 4 is subjected to impact forces from different directions, the rotating part 1301 can rotate freely, driving the damper 1302 and the buffer spring 1303 to adjust their angles, forming an adaptive buffering mechanism. This design enables the buffer part 13 to effectively cope with impacts from multiple directions, improving the reliability of the equipment in complex construction environments. It is especially suitable for situations such as irregular stone rolling or soil lateral pressure fluctuations that may occur during dam construction.

[0019] Please see Figure 5 The drive assembly 11 includes a first bevel gear 17, a second bevel gear 18, and a rotary handle 19. The rotary handle 19 is rotatably connected to the drive chamber 102, and the bottom of the rotary handle 19 passes through the top of the drive chamber 102 and is connected to the first bevel gear 17. The second bevel gear 18 is fixedly connected to the drive wheel, and the first bevel gear 17 and the second bevel gear 18 mesh with each other. The meshing design of the first bevel gear 17 and the second bevel gear 18 converts the horizontal rotational motion of the rotary handle 19 into a vertical rotational force, realizing a 90-degree change in transmission direction. This design allows the operator to easily operate the rotary handle 19 above the base plate 1, making operation more convenient.

[0020] Please refer to 5. The cross section of the movable block 14 is designed in the shape of a cross, and the shape of the movable block 14 matches the internal shape of the movable groove 103. The cooperation between the cross structure and the movable groove 103 can effectively limit the shaking and displacement of the movable block 14, and ensure that the movable block 14 moves stably along the axial direction of the lead screw 12.

[0021] Detailed Implementation: In use, rotating the handle 19 causes the connected first bevel gear 17 to rotate. Since the first bevel gear 17 meshes with the second bevel gear 18, the rotation of the first bevel gear 17 drives the second bevel gear 18 to rotate. The second bevel gear 18 is fixedly connected to the drive wheel of the sprocket transmission mechanism 16, thereby driving the drive wheel to rotate. After the drive wheel rotates, it drives the two driven wheels to rotate through the transmission chain, forming the transmission of the sprocket transmission mechanism 16. The driven wheels are connected to the end of the lead screw 12, thereby driving the lead screw 12 to rotate. When the lead screw 12 rotates, the movable block 14, which cooperates with the lead screw 12, moves along the movable groove 103 under the action of the lead screw 12. The movement of the movable block 14 drives the retaining plate 3 to rotate, thereby realizing the adjustment of the angle of the retaining plate 3 to adapt to different retaining requirements.

[0022] Protective buffer section: The upper surface of the protective buffer plate 4 is concave, and rollers 401 are evenly installed in the concave groove. The rollers 401 are rotatably connected to the protective buffer plate 4. When an object falls on the protective buffer plate 4, the rollers 401 can rotate, reducing the friction between the object and the protective buffer plate 4, thus playing a certain role in buffering and protection. At the same time, a rotating component 1301 is rotatably connected to the bottom of the protective buffer plate 4. A damper 1302 and a buffer spring 1303 are connected to the bottom of the rotating component 1301. A baffle 1305 is fixed to the bottom of the damper 1302. The screw 1304 at the bottom of the baffle 1305 passes through the annular groove 701 on the support rod 7 and is threadedly connected to the threaded sleeve 15. When the protective buffer plate 4 is subjected to impact force, the rotating component 1301 can rotate at a certain angle. At the same time, the damper 1302 and the buffer spring 1303 will play a role in buffering and shock absorption, reducing the impact of the impact force on the equipment and protecting the structural safety of the equipment.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
