Description

Technical Field

[0001] This utility model belongs to the field of tunnel construction technology, and in particular relates to a crushed stone transport device for tunnel construction. Background Technology

[0002] Tunnel construction is a core component of infrastructure development, including highways, railways, water conservancy projects, and urban underground utility tunnels. The construction process generates a large amount of construction waste, such as gravel, rock debris, and dust. If this waste is not collected, transported, and processed in a timely and efficient manner, it will not only continuously occupy limited tunnel working space and hinder the progress of core processes such as excavation and support, but may also cause collapses and landslides due to excessive accumulation, directly threatening the safety of construction workers and the overall project progress.

[0003] Currently available crushed stone handling devices for tunnel construction generally suffer from technical defects such as limited functionality, poor operational adaptability, and low overall efficiency, making it difficult to meet the actual needs of complex tunnel construction environments. Specifically, traditional devices often have fixed, narrow-mouth crushed stone collection ports that lack designs to expand the collection range. When crushed stone is placed, some of it tends to scatter from the edges of the collection port, reducing collection efficiency and requiring additional manpower for cleaning. In addition, some devices do not have suitable storage carriers inside, and direct accumulation of crushed stone can easily lead to local blockages. During tunnel construction, the size of crushed stone varies greatly and often contains larger rock fragments, but most existing devices do not have built-in crushing mechanisms and require pre-crushing by external equipment. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes a crushed stone transport device for tunnel construction, which includes a vehicle body for easy subsequent installation. The outer side of the vehicle body is square, and the inner side is cylindrical. A placement cylinder is provided inside the vehicle body, and a collection cylinder is installed on the top of the placement cylinder. A servo motor is provided on the side wall of the vehicle body, and a first synchronous belt drive assembly is provided at the output end of the servo motor. A rotating shaft is provided inside the vehicle body, and the end of the first synchronous belt drive assembly away from the servo motor is connected to the rotating shaft for transmission. A crushing paddle is provided on the side wall of the rotating shaft, a stirring paddle is provided on the side wall of the rotating shaft, and a second synchronous belt drive assembly is provided on the side wall of the rotating shaft. A dispersion disc is provided at the bottom of the vehicle body, and the end of the second synchronous belt drive assembly away from the rotating shaft is connected to the dispersion disc for transmission.

[0005] In one example, the stone-crushing paddle is positioned above the mixing paddle, with its rotation axis extending through the interior of the vehicle body.

[0006] In one example, the bottom will extend a certain distance, and the first and second synchronous belt drive assemblies are disposed on the sidewall of the extended end of the drive shaft.

[0007] In one example, the first synchronous belt drive assembly is located above the second synchronous belt drive assembly, and the sidewalls of the first and second synchronous belt drive assemblies are provided with protective covers.

[0008] In one example, the axle side wall where the scattering disc connects to the vehicle body is provided with a protective sleeve.

[0009] In one example, the vehicle body has internal threads with bolts, and the side walls of the vehicle body are provided with cover plates.

[0010] The crushed stone transport device for tunnel construction proposed in this utility model can bring the following beneficial effects: 1. This utility model significantly improves the efficiency of collecting and loading crushed stone during tunnel construction. The trumpet-shaped collection cylinder at the top of the device can specifically expand the space for crushed stone placement, which is especially suitable for the relatively narrow working environment inside tunnels. This effectively reduces the occurrence of crushed stone falling due to space constraints during feeding, thereby reducing material loss and the extra workload of manually cleaning up fallen crushed stone. At the same time, the crushing paddle on the side wall of the rotating shaft inside the vehicle can crush larger stones, preventing large pieces of crushed stone from occupying too much loading space. The stirring paddle below can further separate the crushed dust from the fragments, making the fragments more evenly distributed and densely packed in the placement cylinder. The combined effect of these two features greatly improves the overall loading capacity of the device, reduces the number of round trips caused by insufficient single-load transportation, and improves construction efficiency.

[0011] 2. This utility model comprehensively optimizes operational convenience and effectively protects the device while extending its service life. The dispersion disc at the bottom of the vehicle body is linked to the rotating shaft via the second synchronous belt transmission assembly. The spherical part on its side wall can rotate and scrape the accumulated gravel in front when the device moves, automatically creating a clean working path for the device. This eliminates the need for construction personnel to manually clean the road surface beforehand, saving preparation time. During unloading, simply unscrew the bolts inside the vehicle body to open the side wall cover, then start the servo motor to drive the rotating shaft to rotate. The stirring paddle can then smoothly push the gravel and dust in the placement cylinder to the top of the dispersion disc. The dispersion disc then uses the centrifugal force generated by the rotation to throw the gravel to the designated area, preventing the gravel from accumulating and clogging inside the device. In addition, the protective covers on the outside of the first and second synchronous belt transmission assemblies can isolate dust and gravel particles in the tunnel, preventing the gears inside the transmission assembly from jamming or wearing due to contamination. The protective cylinder on the outside of the shaft connecting the dispersion disc and the vehicle body can prevent gravel from directly impacting the shaft, avoiding bending and deformation of the shaft, ensuring the stable operation of the core components of the device, and extending the overall service life.

Detailed Implementation

[0017] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will provide further details.

[0018] Example: like Figures 1-4 As shown in the figure, an embodiment of the present invention proposes a crushed stone transport device for tunnel construction, which includes a vehicle body 11 for easy subsequent installation. The vehicle body 11 provides space for storing crushed stone. The outer side of the vehicle body 11 is square and the inner side is cylindrical, which facilitates the placement of the placement cylinder 12. A trumpet-shaped collection cylinder 13 is installed above the placement cylinder 12. The collection cylinder 13 expands the space for crushed stone to be placed and reduces the possibility of crushed stone falling out of the device when it is placed.

[0019] When larger stones are placed in, the servo motor 14 installed on the side wall of the vehicle body 11 is activated. The servo motor 14 transmits power to the rotating shaft 16 installed inside the vehicle body 11 through the first synchronous belt drive assembly 15 at the output end. The rotating shaft 16 drives the stone crushing paddle 17 on the side wall to rotate, and the stone crushing paddle 17 crushes the stones, increasing the overall loading capacity of the device. At the same time, the rotating shaft 16 also drives the stirring paddle 18 to rotate, which facilitates the separation of crushed dust and fragments, further expanding the loading capacity of the device. Meanwhile, the rotating shaft 16 drives the dispersing disc 21 at the bottom of the vehicle body 11 to rotate through the second synchronous belt drive assembly 19 on the side wall. When the dispersing disc 21 comes into contact with the crushed stones in front, the spherical part on the side wall of the dispersing disc 21 scrapes the crushed stones, forcing the crushed stones to move from the middle to both sides, thereby opening up a clean path.

[0020] The stone crushing paddle 17 is positioned above the stirring paddle 18, and its rotating shaft 16 passes through the interior of the vehicle body 11, with one end extending out from the bottom. The first synchronous belt drive assembly 15 and the second synchronous belt drive assembly 19 are located on the side wall of the end extending out from the bottom of the drive shaft. The first synchronous belt drive assembly 15 is positioned above the second synchronous belt drive assembly 19, and a protective cover 22 is provided on the side wall of the first synchronous belt drive assembly 15 and the second synchronous belt drive assembly 19. The protective cover 22 is to prevent the inside of the drive assembly from being contaminated during use under harsh conditions, which could lead to gear misalignment and increase the service life of the device. The spherical arrangement on the side wall of the dispersing disc 21 can not only clean out the stones, but also act as the teeth of the gears, which can drive the other dispersing disc 21 to rotate in the opposite direction. A protective cylinder 23 is provided on the side wall of the shaft connecting the other dispersing disc 21 to the vehicle body 11 to prevent stones from hitting the side wall of the connected shaft, causing the shaft to bend and the device to malfunction.

[0021] When it is necessary to remove the internal gravel, the bolt 24 with its threaded setting inside the vehicle body 11 is rotated. When the bolt 24 is no longer restricting the cover plate 25 on the side wall of the vehicle body 11, the servo motor 14 is restarted. The servo motor 14 then drives the rotating shaft 16 to rotate, which in turn causes the stirring shaft to rotate, pushing the gravel and dust inside the placement cylinder 12 out of the vehicle body 11 and onto the dispersing disc 21. The dispersing disc 21 then uses centrifugal force to throw the gravel out, thereby preventing the accumulation of gravel.
