Description

Technical Field

[0001] This application relates to the field of water conservancy engineering construction technology, specifically to slope excavation and support devices for water conservancy projects. Background Technology

[0002] Water conservancy projects are critical infrastructure for ensuring people's safety and promoting economic development, encompassing flood control, irrigation, water supply, and power generation. During construction, projects such as reservoirs, dams, and canals often require slope excavation. After excavation, the rock mass's mechanical balance is disrupted, making the slopes susceptible to landslides and collapses due to geological, hydrological, and construction factors, threatening personnel and equipment safety and delaying the project schedule. Therefore, post-excavation slope support is a core element in ensuring project safety, quality, and progress, and is crucial to the overall stability of the project.

[0003] The prior art discloses a slope excavation support device for water conservancy projects, including a rectangular support plate, an anchor bolt assembly, and a splicing connector. The support plate has multiple through holes. The anchor bolt assembly includes an anchor bolt with a threaded section, a fixing nut, and a conical tip. The splicing connector is a U-shaped clamp with threaded holes at both ends, which can be connected to the side of adjacent support plates by bolts. In use, the support plate is placed against the slope surface, the anchor bolt is inserted into the slope rock mass through the through holes, and the support plate is tightened by the fixing nut. Adjacent support plates are connected by the splicing connector to form an integral support structure.

[0004] The support plates, anchor bolt assemblies, and other components of the aforementioned support device require a large number of personnel to handle manually. During installation, multiple people are needed to cooperate in positioning, inserting anchor bolts, and fastening connectors. The laying operation is cumbersome, consumes a lot of manpower, and significantly reduces construction efficiency. Utility Model Content

[0008] Optionally, the support assembly includes a first support rod, a first support cylinder, a second support rod, a second support cylinder, and a slider; wherein, one end of the first support rod is rotatably connected to the transfer vehicle; the fixed end of the first support cylinder is rotatably connected to the transfer vehicle, and the pushing end is rotatably connected to the middle of the first support rod; one end of the second support rod is rotatably connected to the end of the first support rod away from the transfer vehicle, and the other end is rotatably connected to the first support plate, and an adjustment groove is provided on the second support rod; the slider is slidably connected in the adjustment groove; the fixed end of the second support cylinder is rotatably connected to the side of the first support rod opposite to the first support cylinder, and the pushing end is rotatably connected to the slider; wherein there are two of each of the first support cylinder, the first support rod, the second support rod, and the second support cylinder.

[0009] Optionally, the first support plate has a connecting shaft at one end near the second support rod, and the ends of the two second support rods away from the first support rod are rotatably connected to the connecting shaft.

The uniformly permeable holes on the second support plate quickly drain accumulated water, preventing slope rock softening and damage from uneven stress on the support plate, thus extending the device's lifespan. The overall device significantly reduces manpower consumption, solves the problem of low efficiency in existing support laying technologies, and improves adaptability to complex terrain, the integrity and stability of the support structure, balancing functionality and durability.

[0023] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "including," "comprising," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0025] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to facilitate intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationships in the actual product. Changes in these relative positional relationships, without departing from the technical concept disclosed in this application, should also be considered within the scope of this application.

[0026] The following is combined with Figures 1 to 4 The embodiments shown illustrate the technical solution of this utility model:

[0027] This utility model provides a slope excavation and support device for water conservancy projects, such as... Figure 1 and Figure 2 As shown, it includes a transfer vehicle 1, a support assembly 4, a first support plate 2, and a second support plate 3; wherein, the support assembly 4 is installed on the transfer vehicle 1; the first support plate 2 is located above the transfer vehicle 1, one end of the support assembly 4 is connected to the transfer vehicle 1, and the other end is connected to the first support plate 2, and the first support plate 2 has accommodating cavities 201 staggered on both sides; the second support plate 3 is located in the accommodating cavity 201, and the second support plate 3 has a degree of freedom of movement along the depth direction of the accommodating cavity 201.

[0028] Specifically, the transfer vehicle 1 enables mechanized transport of the entire support device and related components, replacing the traditional manual handling method, significantly reducing manpower consumption and greatly improving component transport efficiency. The support component 4, as the connection medium between the transfer vehicle 1 and the first support plate 2, not only provides stable support for the first support plate 2, but also allows for adjustment of the position and angle of the first support plate 2 through its own structural adjustment, enabling it to adapt to slopes of different gradients and enhancing the device's adaptability to slope terrain. The staggered cavities 201 on both sides of the first support plate 2 not only provide precise installation space for the second support plate 3, but also allow the first support plate 2 and the second support plate 3 of adjacent support devices to overlap, effectively avoiding the generation of support gaps and improving the integrity of slope support. The second support plate 3's freedom of movement along the depth direction of the cavities 201 allows for flexible adjustment of its extension length according to the actual height of the slope and the support range, further expanding the support coverage of the device, enhancing its versatility, and comprehensively solving the problem of low support laying efficiency caused by cumbersome manual handling and installation in the existing technology.

[0029] It should be noted that a positioning frame (not shown in the figure) is installed at the opening of the accommodating cavity 201, and a positioning plate (not shown in the figure) is provided on one side of the second support plate 3 that extends into the accommodating cavity 201. The positioning frame is used to restrict the positioning plate inside the accommodating cavity 201 to prevent the second support plate 3 from falling out.

[0030] In an exemplary embodiment, see Figure 2 The support assembly 4 includes a first support rod 401, a first support cylinder 402, a second support rod 403, a second support cylinder 404, and a slider 405. One end of the first support rod 401 is rotatably connected to the transfer vehicle 1. The fixed end of the first support cylinder 402 is rotatably connected to the transfer vehicle 1, and its pushing end is rotatably connected to the middle of the first support rod 401. One end of the second support rod 403 is rotatably connected to the end of the first support rod 401 away from the transfer vehicle 1, and the other end is rotatably connected to the first support plate 2. An adjustment groove 4031 is provided on the second support rod 403. The slider 405 is slidably connected in the adjustment groove 4031. The fixed end of the second support cylinder 404 is rotatably connected to the side of the first support rod 401 away from the first support cylinder 402, and its pushing end is rotatably connected to the slider 405. There are two first support cylinders 402, 401, 403, and 404.

[0031] Specifically, the symmetrical arrangement of the two first support rods 401 and the two first support cylinders 402 provides balanced symmetrical support force for the first support plate 2, significantly improving support stability. The first support cylinder 402, by pushing the middle of the first support rod 401, drives the first support rod 401 to rotate around its connection point with the transfer vehicle 1, thereby adjusting the tilt angle of the first support rod 401. This, in turn, drives the second support rod 403 and the first support plate 2 to complete initial height and angle adjustments, laying the foundation for subsequent precise positioning. The adjustment groove 4031 on the second support rod 403 provides a stable sliding track for the slider 405, which acts as the connection between the second support cylinder 404 and the second support plate 2. The connecting medium of the support rod 403 allows the second support cylinder 404 to move the slider 405 within the adjustment groove 4031, driving the second support rod 403 to rotate around its connection point with the first support rod 401. This enables fine-tuning of the angle and position of the first support plate 2, ensuring that the support plate can precisely conform to the slope surface and adapt to complex slope changes. The cooperation between the two second support cylinders 404 and the two second support rods 403 further enhances the symmetry and synchronization of the support adjustment, ensuring that the first support plate 2 remains stable throughout the adjustment process. At the same time, the mechanized adjustment method replaces manual adjustment, saving labor costs and improving the efficiency and accuracy of support position adjustment.

[0032] When not providing support, the first support plate 2 can be horizontally covered on the top of the transfer vehicle 1 by retracting the first support cylinder 402, while simultaneously concealing the support assembly 4 inside the transfer vehicle 1.

[0033] In an exemplary embodiment, see Figure 2 The first support plate 2 has a connecting shaft 202 at one end near the second support rod 403, and the ends of the two second support rods 403 away from the first support rod 401 are rotatably connected to the connecting shaft 202.

[0034] Specifically, the connecting shaft 202 serves as a common rotating connection component between the two second support rods 403 and the first support plate 2, achieving a centralized connection between the two second support rods 403 and the first support plate 2, reducing installation difficulty and assembly complexity. Simultaneously, the rotation of the two second support rods 403 around the same connecting shaft 202 ensures that the direction and adjustment range of their forces on the first support plate 2 remain coordinated and synchronized during adjustment, avoiding asynchronous adjustment problems caused by the separate connections of the two second support rods 403 to the first support plate 2. This prevents the first support plate 2 from twisting, deforming, or experiencing uneven stress, significantly improving the stability of the first support plate 2 during adjustment and the structural stability during support operations, thus ensuring the overall support effect.

[0035] In an exemplary embodiment, see Figure 3 and Figure 4The transfer vehicle 1 includes a vehicle body 101, track wheels 102, a lifting component 103, and a drive component 104. The vehicle body 101 is a box with an open top and one vertical side. There are two sets of track wheels 102, symmetrically arranged on both sides of the vehicle body 101. The lifting component 103 is located on the vehicle body 101, and the lifting end is connected to the track wheels 102. The drive component 104 is located at the bottom of the vehicle body 101 and provides power for the operation of the track wheels 102.

[0036] Specifically, the vehicle body 101 adopts a box structure with an open top and one vertical side. The open top facilitates the installation, debugging, and maintenance of the support assembly 4 and the first support plate 2, while the open side reduces spatial interference between the vehicle body 101 and the slope when the device is close to the slope, making it easier to place the first support plate 2 and the second support plate 3 close to the slope for support operations. At the same time, the box structure provides effective protection for internal components such as the drive component 104, avoiding damage to components caused by impacts from debris and dust accumulation during construction. Compared with traditional wheels, the two sets of symmetrically arranged track wheels 102 increase the contact area with the ground and reduce the ground pressure, enabling them to stabilize on soft and uneven ground at the hydraulic engineering construction site. The fixed-route design significantly improves the site adaptability of the device; the lifting component 103 can flexibly adjust the overall height of the vehicle body 101 by adjusting the height of the track wheels 102. On the one hand, it can adapt to the terrain at the bottom of slopes of different heights, ensuring that the vehicle body 101 is placed stably. On the other hand, it can work with the support component 4 to adjust the initial height of the first support plate 2, providing a basis for the precise adjustment of the subsequent support position; the drive component 104 provides stable power to the track wheels 102, realizing the mechanized movement of the transfer vehicle 1, replacing manual pushing, saving labor costs, and can adjust the movement speed according to construction needs, improving the transfer efficiency of the device between different support operation points on the construction site, and further improving the overall construction efficiency.

[0037] In an exemplary embodiment, see Figure 3 and Figure 4 The bottom of the vehicle body 101 has four mounting slots 1011. The lifting component 103 includes a lifting cylinder 1031 and a connecting block 1032. There are four lifting cylinders 1031, which are respectively located in the four mounting slots 1011. The connecting block 1032 is located at the connection between the pushing end of the lifting cylinder 1031 and the track wheel 102. The track wheel 102 and the lifting cylinder 1031 are respectively connected to two mutually perpendicular surfaces of the connecting block 1032.

[0038] Specifically, the four mounting slots 1011 at the bottom of the vehicle body 101 provide embedded mounting space for the lifting cylinders 1031, allowing the lifting cylinders 1031 to be integrated inside the vehicle body 101, making the overall structure of the transport vehicle 1 more compact and facilitating operation in narrow construction areas. The four lifting cylinders 1031 correspond to the support points of the four track wheels 102, enabling independent height adjustment of each track wheel 102. When there are height differences on the construction site ground, by adjusting the extension and retraction of the lifting cylinders 1031 at different positions, the vehicle body 101 can be quickly kept level, preventing the vehicle body 101 from becoming uneven. The tilting causes instability in the support assembly 4 and the support plate, greatly improving the device's adaptability to uneven ground. The connecting block 1032 serves as a transitional connection between the lifting cylinder 1031 and the track wheel 102, connecting the two on mutually perpendicular surfaces. This ensures that the extension and retraction force of the lifting cylinder 1031 can be transmitted vertically and efficiently to the track wheel 102, avoiding the track wheel 102 from getting stuck due to force transmission deviation. At the same time, it enhances the firmness of the connection between the lifting cylinder 1031 and the track wheel 102, preventing the problems of detachment or damage that are easy to occur when the two are directly connected, and ensuring the stable and reliable realization of the lifting function.

[0039] In an exemplary embodiment, see Figure 4 The drive unit 104 includes a drive shaft 1041, a first bevel gear 1042, a second bevel gear 1043, a drive shaft 1044, and a drive motor 1045. The two ends of the drive shaft 1041 pass through adjacent connecting blocks 1032 and are fixedly connected to the track wheel 102. The first bevel gear 1042 is mounted on the drive shaft 1041. The second bevel gear 1043 meshes with the first bevel gear 1042. One end of the drive shaft 1044 is coaxially connected to the second bevel gear 1043. The drive motor 1045 is located at the bottom of the vehicle body 101, and its drive end is coaxially connected to the end of the drive shaft 1044 away from the second bevel gear 1043.

[0040] Specifically, both ends of the drive shaft 1041 are fixedly connected to two track wheels 102 on the same side. The meshing of the first bevel gear 1042 and the second bevel gear 1043 can convert the direction of power transmitted by the drive motor 1045 through the drive shaft 1044. This adapts to the difference in installation position between the drive motor 1045 and the track wheels 102 at the bottom of the vehicle body 101, making the drive structure layout more reasonable, making full use of the space at the bottom of the vehicle body 101, and avoiding component interference. The drive motor 1045 serves as a power source, transmitting power through the drive shaft 1044. The first bevel gear 1042, the second bevel gear 1043, and the drive shaft 1041 stably transmit power to the track wheel 102, realizing the mechanized drive of the track wheel 102. Compared with manual drive, the power output is more stable and controllable, and the moving speed of the transfer vehicle 1 can be flexibly adjusted according to construction needs, significantly improving the moving efficiency. At the same time, the drive motor 1045 is installed at the bottom of the vehicle body 101, avoiding occupying the space on the top of the vehicle body 101 used for installing the support component 4 and the support plate, thus ensuring the rationality and functionality of the overall structural layout of the device.

[0041] In an exemplary embodiment, see Figure 3 and Figure 4 The lifting component 103 also includes a fixing pin 1033, one end of which is located on the side of the connecting block 1032 opposite to the lifting cylinder 1031, and the extended end of the fixing pin 1033 extends away from the end of the lifting cylinder 1031.

[0042] Specifically, the fixing nail 1033 is integrated on the ground-facing side of the connecting block 1032. When the lifting component 103 drives the connecting block 1032 to descend via the lifting cylinder 1031, the fixing nail 1033 can be inserted into the ground along with the connecting block 1032. Through the mechanical interlocking action of the fixing nail 1033 with the ground soil or rock, the connection between the transport vehicle 1 and the ground is greatly enhanced. In addition, the fixing nail 1033 is directly integrated on the connecting block 1032 of the lifting component 103, eliminating the need for an additional independent fixing device. This simplifies the device structure and reduces the complexity of operation. Fixing can be completed while the lifting cylinder 1031 adjusts the height of the vehicle body 101 and ensures stability, without the need for additional procedures, further improving the efficiency of support operations.

[0043] In an exemplary embodiment, see Figure 2 The second support plate 3 has several water-permeable holes 301 evenly distributed on it.

[0044] Specifically, the permeable holes 301 on the second support plate 3 allow rainwater, rock seepage, or construction water on the slope surface to drain quickly during the support process, preventing rainwater and water from accumulating between the second support plate 3 and the slope. This effectively reduces the soaking of the slope rock by accumulated water and significantly improves the safety of the support operation. At the same time, the evenly distributed permeable holes 301 ensure uniform drainage, preventing excessive pressure on the second support plate 3 due to localized water accumulation. This prevents the second support plate 3 from bending, deforming, or being damaged due to uneven stress, thus extending the service life of the device. Furthermore, by rationally designing the pore size and distribution density of the permeable holes 301, the drainage function can be guaranteed without significantly reducing the structural strength of the second support plate 3, ensuring that it can continuously provide stable support force for the slope, thus balancing drainage and support performance.

[0045] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0046] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
