Description

Technical Field

[0001] This utility model relates to the field of mountain transportation vehicle technology, and in particular to a tracked integrated transport and transfer vehicle. Background Technology

[0002] Currently, in the field of mountain engineering construction, especially in projects such as power engineering, photovoltaic power stations, and wind turbine foundations, material transportation remains a key factor restricting construction efficiency and quality. Due to factors such as rugged mountain terrain and poor road conditions, the mobility of traditional wheeled transportation equipment is limited, while tracked transportation equipment, with its excellent off-road performance, is gradually becoming the mainstream choice for mountain transportation.

[0003] In the prior art, Chinese patent CN214728402U discloses a remote-controlled tracked multi-functional mountain transporter, including a frame and a hopper. A column is connected to the frame, and a mounting base is connected to the top of the column. A wire rope drum is supported on the mounting base and connected to a hydraulic motor. A boom is connected to the upper end of the column, and a fixed pulley is connected to the other end of the boom. A movable pulley is set below the fixed pulley. One end of the wire rope is connected to the fixed pulley, and the wire rope passes through the movable pulley and the fixed pulley before connecting to the wire rope drum. A hook is connected to the movable pulley. A bracket is connected to the front end of the frame. A bracket assembly is detachably connected to the upper end of the bracket and the upper end of the hopper. The bracket assembly includes a channel steel, a pressure block, and two rotating shafts. The lower end of the rotating shaft is connected to the channel steel and is threaded. Through holes are set at both ends of the pressure block, and the two rotating shafts pass through the through holes of the pressure block and are connected to nuts.

[0004] While the existing mountain transport vehicles have achieved the transportation of materials such as long power poles, sand and gravel, and construction equipment, the following shortcomings still exist in actual use: First, these transport vehicles only have loading functions and lack a mixing mechanism for concrete. During the secondary transportation of concrete, the lack of continuous mixing can easily lead to aggregate settling and stratification, affecting the quality of cast-in-place piles. Furthermore, the concrete is prone to solidification and clumping when left undisturbed, resulting in material waste and increased on-site cleanup work. Second, these transport vehicles primarily focus on transporting bulk materials such as long power poles and sand and gravel, and cannot simultaneously transport small components such as anchor bolts and steel piles required for cast-in-place pile construction. Additional transport vehicles are needed, leading to a cumbersome and inefficient construction process. Third, the unloading method of these transport vehicles is designed for solid materials, making it difficult to adapt to the precise control requirements for discharge speed and direction during concrete pouring. This can easily cause concrete spillage, further exacerbating material waste and on-site pollution. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of existing transport machines, such as inconvenience in transporting concrete, lack of mixing function, and difficulty in adapting to concrete unloading, and to provide a tracked transport and transfer integrated vehicle.

[0006] This utility model is achieved through the following technical solution: a tracked transport and transfer integrated vehicle, including a frame body, a driver's cab at the front of the frame body, and track devices on both sides of the frame body; a stabilizing mechanism at the rear of the frame body, a hopper placed on the stabilizing mechanism, with a feed inlet at the top and a discharge outlet at the bottom of the hopper; a connecting mechanism at the feed inlet of the hopper, a motor connected to the connecting mechanism, and a stirring unit extending into the hopper connected to the output shaft of the motor, with a lifting ring at the end of the motor away from its output shaft; a rotating boom on the frame body, equipped with a hook that cooperates with the lifting ring, and the rotating boom can lift the hopper through the lifting ring and the hook.

[0007] This invention solves the problem of mountainous terrain access through a tracked device; the mixing unit directly acts on the concrete in the hopper, overcoming the defects of concrete stratification and solidification during static setting in the prior art, thus ensuring construction quality; the combination of the rotating boom and the PLC control system realizes automated control of hopper hoisting and unloading, precisely adjusting the discharge speed and direction to reduce spillage and waste; the integrated design eliminates the need for additional transportation equipment, effectively improving construction efficiency.

[0008] A further improvement of this utility model is that the stabilizing mechanism includes multiple stabilizing columns, which surround the rear of the vehicle frame body to form a placement space for placing and positioning the hopper.

[0009] A further improvement of this utility model is that the connecting mechanism includes multiple connecting rods, which are evenly and obliquely spaced along the circumference, and the top ends of the multiple connecting rods are connected to the motor, and the bottom ends of the multiple connecting rods are respectively connected to the edge of the feed inlet.

[0010] A further improvement of this utility model is that the stirring unit includes a rotating shaft, the top end of which is connected to the output shaft of the motor, the bottom end of which extends into the hopper, and a paddle impeller is provided on the outside of the rotating shaft.

[0011] A further improvement of this utility model is that the hopper includes a cylindrical hopper body, and the bottom end of the cylindrical hopper body is provided with a conical hopper bottom.

[0012] A further improvement of this utility model is that a material trough is provided on the frame body.

[0013] A further improvement of this utility model is that the driver's cab, the rotating boom, and the material trough are arranged side by side.

[0014] A further improvement of this utility model is that baffles are provided around the frame body.

[0015] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0016] 1. This utility model, through the combination of tracked devices and the chassis body, enables stable travel on rugged terrain, solving the problem of insufficient mobility of traditional wheeled equipment. It eliminates the need for large-scale modifications to mountainous areas, reducing environmental damage. Simultaneously, the coordinated lifting of the rotating boom and bucket, coupled with remote control via a PLC system, achieves integrated operation from concrete transportation to pouring, avoiding manual labor and material loss during secondary transfers, significantly improving construction efficiency. It is particularly suitable for mountainous engineering scenarios such as photovoltaic cast-in-place piles and wind turbine foundations.

[0017] 2. The mixing unit inside the hopper of this utility model is continuously driven by an electric motor, which can effectively prevent the concrete from separating and solidifying during transportation, ensuring stable concrete performance and guaranteeing the quality of the cast-in-place piles from the source. In addition, the conical bottom design of the hopper, combined with the controllable discharge port, can precisely adjust the discharge speed and direction of the concrete, reducing the spillage problems common in traditional unloading methods, reducing material waste and on-site pollution, and also reducing the workload of subsequent cleanup.

[0018] 3. The material trough on the frame of this utility model can simultaneously transport small accessories such as anchor bolts and steel piles, eliminating the need for additional transportation vehicles, avoiding the cumbersome process of coordinating multiple devices, and shortening the construction cycle. The stabilizing and connecting mechanisms enhance the overall operational stability of the equipment, reduce component wear during transportation, and extend the equipment's service life. Overall, this solution demonstrates significant comprehensive benefits in improving construction efficiency, ensuring project quality, and reducing construction costs and environmental impact.

Detailed Implementation

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] Now refer to Figures 1-3 The following is a description of a specific embodiment: The tracked transport and transfer vehicle of this utility model includes a chassis body 11. Referring to existing crane and tracked technology, a driver's cab 7 is provided at the front of the chassis body 11, and track devices 10 are respectively provided on both sides of the chassis body 11. A stabilizing mechanism is provided at the rear of the chassis body 11, and a hopper 8 is placed on the stabilizing mechanism. The top of the hopper 8 is provided with a feed inlet 803, and the bottom is provided with a discharge outlet 9. Referring to existing industrial hoppers, the discharge outlet 9 can be equipped with removable sealing components such as plugs and sealing caps. A connecting mechanism is provided at the feed inlet 803 of the hopper 8. The vehicle frame 11 is equipped with a motor 2, and the output shaft of the motor 2 is connected to a stirring unit extending into the hopper 8. A lifting ring 1 is provided at the end of the motor 2 away from its output shaft. A rotating boom 13 is provided on the frame body 11. The rotating boom 13 can be of the DES PJB-S, BZD column type, BZ-W folding boom type, etc. The rotating boom 13 is equipped with a hook 14 that cooperates with the lifting ring 1. The rotating boom 13 can lift the hopper 8 through the lifting ring 1 and the hook 14. The cab 7 can remotely control the operation of the motor 2 and the rotating boom 13 through a PLC control system. The above-mentioned remote control technology can refer to existing automation control and communication technologies.

[0026] The chassis body 11 adapts to rugged mountainous terrain via side track devices 10, and the PLC control system in the cab 7 enables remote and precise control of the motor 2 and the rotating boom 13. During transportation, the hopper 8 is placed on the stabilizing mechanism at the rear of the vehicle, which limits the hopper's swaying. When concrete needs to be mixed, the motor 2 drives the mixing unit extending into the hopper 8 to operate continuously, preventing the concrete from separating or solidifying. During unloading, the rotating boom 13 engages with the lifting ring 1 at the top of the hopper 8 via the hook 14 to lift the hopper 8 to the designated position, and then pours the concrete from the bottom outlet 9.

[0027] This utility model solves the problem of mountainous terrain access through the tracked device 10; the mixing unit directly acts on the concrete in the hopper 8, overcoming the defects of concrete stratification and solidification in the prior art, and ensuring construction quality; the rotating boom 13 is combined with the PLC control system to realize the automated control of hoisting and unloading of the hopper 8, accurately adjust the discharge speed and direction, and reduce spillage and waste; the integrated design eliminates the need for additional transportation equipment and can effectively improve construction efficiency.

[0028] Specifically, refer to Figure 3 The stabilizing mechanism includes multiple stabilizing columns 6, which surround the rear of the frame body 11 to form a placement space 15 for placing and positioning the hopper 8.

[0029] Multiple stabilizing columns 6 surround the rear of the frame body 11 to form a placement space 15. After the hopper 8 is embedded in this space, the columns form a radial limit on the hopper 8 from all sides to prevent the hopper from shifting laterally or tilting due to bumps during transportation.

[0030] This invention enhances the stability of the hopper 8 through physical limiting, reduces shaking and spillage during concrete transportation, reduces on-site cleanup workload, and avoids collision damage to the hopper 8, thus extending the service life of the equipment.

[0031] Specifically, refer to Figure 2 The connecting mechanism includes multiple connecting rods 3, which are evenly spaced and inclined in the circumferential direction. The top ends of the multiple connecting rods 3 are connected to the motor 2, and the bottom ends of the multiple connecting rods 3 are respectively connected to the edge of the feed inlet 803.

[0032] Multiple connecting rods 3 are evenly inclined around the circumference, with their top ends fixing the motor 2 and their bottom ends connecting to the edge of the feed inlet 803 of the hopper 8, forming a triangular stable support structure to counteract the radial vibration generated when the motor 2 is running.

[0033] This invention, through the aforementioned connecting mechanism, ensures the rigidity of the connection between the motor 2 and the hopper 8, avoids uneven mixing caused by vibration displacement of the mixing unit, reduces component wear, and improves the reliability of equipment operation.

[0034] Specifically, refer to Figure 2 The stirring unit includes a rotating shaft 5, the top end of which is connected to the output shaft of the motor 2, the bottom end of which extends into the hopper 8, and a paddle impeller 4 is provided on the outside of the rotating shaft 5.

[0035] The output shaft of the electric motor 2 drives the rotating shaft 5 to rotate, which in turn drives the impeller 4 to rotate at high speed in the hopper 8, forming a composite mixing of axial and radial forces on the concrete and breaking the tendency of aggregate settling.

[0036] This invention can solve the problem of concrete stratification by continuous stirring, avoid solidification and clumping, and reduce material waste; the structural design of the paddle impeller 4 can be adapted to concrete with different slump, ensuring uniform mixing and improving the quality of cast-in-place piles.

[0037] Specifically, refer to Figure 2 The hopper 8 includes a cylindrical hopper body 801, and a conical hopper bottom 802 is provided at the bottom end of the cylindrical hopper body 801.

[0038] The cylindrical bucket body 801 provides ample mixing space to ensure that the concrete is in full contact with the paddle impeller 4; the conical bucket bottom 802 uses gravity to guide the concrete to gather towards the bottom discharge port 9, reducing residue.

[0039] This invention accelerates the concrete unloading speed through a conical structure, which can prevent material accumulation on the inner wall of the hopper 8, while also facilitating the control of the discharge flow rate, adapting to the needs of different pouring scenarios, and improving unloading efficiency.

[0040] In one embodiment, reference Figure 1 The frame body 11 is provided with a material trough 12.

[0041] The material trough 12 on the frame body 11 can be loaded with small construction accessories such as anchor bolts and steel piles, forming a main material + auxiliary material collaborative transportation mode with the concrete in the hopper 8.

[0042] This utility model eliminates the need for additional transportation vehicles through the design of the material trough 12, simplifies the construction process, reduces the number of round trips, lowers equipment investment costs, and improves the collaborative efficiency of mountain construction.

[0043] In one embodiment, reference Figure 1 The driver's cab 7, the rotating boom 13, and the material trough 12 are arranged side by side.

[0044] The cab 7, the rotating boom 13, and the material trough 12 are arranged side by side. The operator can directly monitor the boom's operating status and the material trough 12's loading status through the cab 7, thus shortening the operation response distance.

[0045] This utility model, through the above-mentioned optimization of equipment space layout, can improve operational convenience, reduce blind spots for drivers, reduce safety risks during hoisting and transportation, and improve the efficiency of multi-process collaborative operations.

[0046] In one embodiment, reference Figure 1 The frame body 11 is provided with baffles 1101 around its perimeter.

[0047] The baffles 1101 around the frame body 11 form a protective barrier to prevent materials such as concrete splashes and falling parts from polluting the external environment or causing collisions with the equipment during transportation.

[0048] This invention reduces the damage to the ecological environment caused by mountain construction through the above design, reduces material loss and the probability of equipment damage, and also reduces the amount of on-site cleanup work in the later stage, which meets the requirements of green construction.

[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
