Description

Technical Field

[0001] This utility model relates to the field of material transportation technology, specifically to a slope material transportation device. Background Technology

[0002] Currently, most water conservancy projects have trapezoidal cross-sections for flood discharge or water supply. In recent years, due to the influence of ecological and environmental protection concepts, the application of cast-in-place concrete slope protection has decreased, and concrete interlocking bricks or ecological blocks are more commonly used for protection.

[0003] In practice, centralized unloading and manual secondary transfer to the work surface are often adopted, or the material is lifted to the work surface with the assistance of a crane. Concrete interlocking bricks or eco-friendly blocks have a large individual weight, making manual handling on slopes a significant safety hazard and inefficient. Using a crane would reduce efficiency due to frequent crane movements on the work surface, and using multiple cranes would increase equipment investment, making it economically infeasible. Furthermore, the lifting process is prone to falling objects or mechanical injuries.

[0004] Therefore, designing a slope material transport device that can improve efficiency, reduce costs and safety hazards is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a slope material transportation device. The transport vehicle slides on the conveying track and, in conjunction with the drive mechanism, can realize the stable transportation of materials along the slope. Compared with manual handling, it greatly improves the transportation efficiency, and compared with crane handling, it improves the safety and reliability.

[0006] To address the aforementioned technical problems, the present invention provides a slope material transport device, comprising a transport track, a transport vehicle, and a drive mechanism. Two transport tracks are arranged parallel to each other at a lateral interval, and the length of the transport tracks extends along the transport direction. The transport vehicle is slidably mounted on the two transport tracks, and the drive mechanism drives the transport vehicle to slide on the transport tracks. A lateral adjustment mechanism is provided between the two transport tracks, which connects the two transport tracks and adjusts the distance between them. The transport track is composed of multiple track units spliced ​​together, and adjacent track units are detachably fixed by longitudinal connectors.

[0007] Furthermore, the track unit is provided with mounting cavities at both ends, and the longitudinal connector is provided with insertion parts at both ends that are adapted to the mounting cavities. The insertion parts are inserted into and detachably fixed in the mounting cavities on the corresponding sides.

[0008] Furthermore, the track unit has a first through hole on each side of the lateral side corresponding to the position of the mounting cavity, and the insertion part has a second through hole corresponding to the position of the first through hole. It also includes a first fastening pin, which passes through the first through hole and the second through hole.

[0009] Furthermore, the longitudinal connector is a cylindrical structure of equal diameter adapted to the mounting cavity. The depth of the mounting cavity is not less than half the length of the longitudinal connector. The longitudinal connector is completely submerged in the corresponding two mounting cavities, and the opposite ends of the adjacent track units are arranged in abutment.

[0010] Furthermore, the lateral adjustment mechanism includes a first lateral member, a second lateral member, and a fixing structure. The first lateral member and the second lateral member are arranged to slide relative to each other in the lateral direction. The opposite ends of the first lateral member and the second lateral member are respectively fixedly connected to the opposite sides of the two conveying tracks. The fixing structure is used to connect and fix the first lateral member and the second lateral member after they have slid into place.

[0011] Furthermore, the first transverse member is provided with a plurality of third through holes spaced apart along the transverse direction, and the second transverse member is provided with a plurality of fourth through holes correspondingly along the transverse direction. The fixing structure includes a second fastening pin passing through the corresponding third through hole and fourth through hole.

[0012] Furthermore, the first transverse member includes two first crossbars arranged at intervals along the conveying direction, and the second transverse member includes two second crossbars arranged at intervals along the conveying direction. The two second crossbars are inserted between the two first crossbars, and the two first crossbars and the two second crossbars are respectively provided with a third through hole and a fourth through hole.

[0013] Furthermore, the transport vehicle is provided with a set of traveling wheels corresponding to the positions of the two conveying tracks. The traveling wheels are H-shaped wheels, which are engaged and roll on the conveying tracks.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] (1) Two parallel conveyor tracks are arranged at transverse intervals, and the transport vehicle slides on them. With the help of the drive mechanism, the materials can be transported stably along the slope. Compared with manual handling, the transport efficiency is greatly improved, and compared with crane handling, the safety and reliability are improved. The transverse adjustment mechanism can adjust the distance between the two conveyor tracks. On the one hand, it can adapt to different working scenarios with different size requirements, increasing the versatility of the device and avoiding the need to frequently change equipment due to different working surfaces, thus reducing costs. On the other hand, it can adapt to the size of the transport vehicle and the amount of transported in a single trip.

[0016] The conveyor track is composed of multiple track units spliced ​​together, with adjacent track units detachably fixed via longitudinal connectors. This allows for flexible assembly according to the actual slope length, improving the device's applicability. Furthermore, compared to a monolithic track, maintenance is more convenient, as damaged track units can be replaced individually, reducing maintenance costs. On the other hand, since slope protection requires sequential laying along the transverse direction, the detachable conveyor track facilitates disassembly and reassembly when the transport location needs to be changed, improving operational efficiency.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings: Specific Implementation Example 1:

[0028] In this embodiment, as Figure 1 As shown, the spacing between the two conveying tracks 1 is in the horizontal direction, and the length direction of the two conveying tracks 1 is in the vertical direction.

[0029] refer to Figures 1 to 7 This utility model discloses a material transport device for a ramp 7 (hereinafter referred to as the transport device), comprising a transport track 1, a transport vehicle 2, and a drive mechanism 3. Two parallel transport tracks 1 are arranged at transverse intervals, with their lengths extending along the transport direction. The transport vehicle 2 is slidably mounted on the two transport tracks 1. The drive mechanism 3 drives the transport vehicle 2 to slide on the transport tracks 1. A transverse adjustment mechanism 4 is provided between the two transport tracks 1, connecting the two transport tracks 1 and adjusting the distance between them. The transport track 1 is composed of multiple track units 11 spliced ​​together, and adjacent track units 11 are detachably fixed together by longitudinal connecting members 5.

[0030] Preferably, in this embodiment, the track unit 11 has mounting cavities 12 at both ends, and the longitudinal connector 5 has insertion parts at both ends that are adapted to the mounting cavities 12. The insertion parts are inserted into and detachably fixed in the mounting cavities 12 on the corresponding sides. The insertion parts cooperate with the mounting cavities 12 to ensure transportation stability.

[0031] Specifically, such as Figure 2 , 5 As shown, the track unit 11 has first through holes 13 on both sides corresponding to the mounting cavity 12, and the insertion part of the longitudinal connector 5 has a second through hole 51 corresponding to the first through hole 13. It also includes a first fastening pin 6, which passes through the first through hole 13 and the second through hole 51 laterally. Laterally, the inner end of the first fastening pin 6 extends outward from the inside of the track unit 11. The inner end of the first fastening pin 6 has a threaded section, on which a fastening nut 48 is threaded to fix both ends of the longitudinal connector 5 to the corresponding mounting cavity 12, thus enabling the fixed installation of two adjacent track units 11 using the longitudinal connector 5.

[0032] In this embodiment, the longitudinal connector 5 is a cylindrical structure of equal diameter adapted to the mounting cavity 12. The depth of the mounting cavity 12 is not less than half the length of the longitudinal connector 5, so that the longitudinal connector 5 is completely submerged in the corresponding two mounting cavities 12, and the opposite ends of adjacent track units 11 are arranged in contact. This design makes the connection between the track units 11 tight and stable, improves the overall strength and stability of the conveying track 1, ensures smooth transportation, improves transportation efficiency, and reduces safety hazards. At the same time, the tight connection also helps to reduce wear at the track connection points and reduce maintenance costs.

[0033] Specifically, in this embodiment, the track unit 11 is a square tube structure, and its inner hole forms the mounting cavity 12. Of course, in other embodiments, depending on actual needs, the track unit 11 may only have inwardly extending countersunk holes at both ends to form the mounting cavity 12.

[0034] Preferably, in this embodiment, the lateral adjustment mechanism 4 includes a first lateral member 41, a second lateral member 42, and a fixing structure, wherein the first lateral member 41 and the second lateral member 42 are slidably arranged relative to each other in the lateral direction, the opposite ends of the first lateral member 41 and the second lateral member 42 are respectively fixedly connected to the opposite sides of the two conveying tracks 1, and the fixing structure is used to connect and fix the first lateral member 41 and the second lateral member 42 after they have slid into place.

[0035] Specifically, the first transverse member 41 and the second transverse member 42 are arranged close to the side of the conveying track 1 facing the slope 7, so as to avoid affecting the movement of the transport vehicle 2.

[0036] Preferably, in this embodiment, the first transverse member 41 is provided with a plurality of third through holes 43 spaced laterally along the transverse direction, and the second transverse member 42 is provided with a plurality of fourth through holes 44 correspondingly along the transverse direction. Both the third through holes 43 and the fourth through holes 44 extend along the conveying direction. The fixing structure includes a second fastening pin 47 passing through the corresponding third through holes 43 and fourth through holes 44. The lower end of the second fastening pin 47 (i.e., the end facing the bottom of the slope) is also provided with a threaded section, and a fastening nut 48 is threadedly connected to the threaded section.

[0037] By sliding the first transverse member 41 and the second transverse member 42 relative to each other in the transverse direction, the distance between the two conveying tracks 1 is changed. When the position is appropriate, the third through hole 43 on the first transverse member 41 is aligned with the corresponding fourth through hole 44 on the second transverse member 42. Then, the second fastening pin 47 is inserted into the third through hole 43 and the fourth through hole 44, and with the fastening nut 48, the first transverse member 41 and the second transverse member 42 are fixedly connected together.

[0038] Specifically, in this embodiment, the first transverse member 41 includes two first transverse bars 45 spaced apart along the conveying direction, and the second transverse member 42 includes two second transverse bars 46 spaced apart along the conveying direction, with the two second transverse bars 46 inserted between the two first transverse bars 45. Along the conveying direction, the opposite sides of the two second transverse bars 46 are respectively abutted against the opposite sides of the two first transverse bars 45, realizing transverse sliding between the second transverse bars 46 and the first transverse bars 45. A third through hole 43 and a fourth through hole 44 are respectively provided on the two first transverse bars 45 and the two second transverse bars 46.

[0039] In this embodiment, based on the actual slope length of the ramp 7 and transportation requirements, multiple sets of the lateral adjustment mechanism 4 can be set at intervals along the conveying direction.

[0040] In other embodiments, the first transverse member 41 may be a sleeve structure, and the second transverse member 42 may be a slide rod structure that passes through the sleeve in the transverse direction.

[0041] In other embodiments, the mounting cavity 12 and the longitudinal connector 5 can be fixedly connected by bolt assemblies passing through the first through hole 13 and the second through hole 51. The first transverse member 41 and the second transverse member 42 are fixedly connected by bolt assemblies passing through the third through hole 43 and the fourth through hole 44.

[0042] Preferably, in this embodiment, in order to improve the stability of the conveying track 1, multiple fixing nails (not shown in the figure) can be set at intervals along the conveying direction on the side of the conveying track 1 facing the slope 7. The fixing nails are inserted into the slope 7 to play a role in anti-slip fixing.

[0043] Preferably, in this embodiment, the transport vehicle 2 includes a vehicle body 21. A set of traveling wheels 24 is respectively arranged on the side of the vehicle body 21 facing the transport track, corresponding to the positions of the two transport tracks 1. Each set of traveling wheels 24 includes two traveling wheels 24 spaced apart along the transport direction. Specifically, the traveling wheels 24 are as follows... Figure 6 , 7 The H-shaped wheel shown has a central opening width that matches the transverse width of the conveying track 1, and the H-shaped wheel is engaged and rolls on the conveying track 1.

[0044] Specifically, in this embodiment, a support shaft 22 connects two corresponding travel wheels 24 in the horizontal direction, and the two travel wheels 24 are rotatably mounted at both ends of the corresponding support shaft 22. A support rod 23 extending towards the vehicle body 21 is fixedly installed on both sides of the support shaft 22, between the two travel wheels 24, with one end of the support rod 23 facing the vehicle body 21 fixed to the vehicle body 21. This achieves the assembly of the travel wheels 24 with the vehicle body 21. The travel wheels 24 are H-shaped wheels and are locked and roll on the conveyor track 1, making the transport vehicle 2 run more stably on the conveyor track 1, reducing the risk of derailment and other dangerous situations, and improving the safety of the transportation process. Compared with manual handling on an inclined plane, this greatly reduces safety hazards, and the stable operation also helps to improve transportation efficiency.

[0045] Preferably, in this embodiment, such as Figure 1 , 4 As shown, the drive mechanism 3 includes a winding machine 31 and a traction rope 32. The winding machine 31 is located at the top of the slope 7. The traction rope 32 connects the winding machine 31 and the vehicle body 21. Specifically, the end of the traction rope 32 facing the vehicle body 21 is divided into three branches, which are respectively connected to the two lateral sides and the midpoint of the side of the vehicle body 21 facing the winding machine 31, to ensure that the vehicle body 21 is under stable force and that the transport vehicle 2 moves stably during the traction process.

[0046] The working process of this application:

[0047] First, transport the components of the transport device to the construction site. Based on the length of the slope 7, determine the number of track units 11 required. Then, place each track unit 11 on the slope using longitudinal connectors 5, first fastening pins 6, and fastening nuts 48 to form the transport track 1.

[0048] The size of the transport vehicle 2 is determined according to the specifications of the transported materials. The distance between the two transport tracks 1 is determined according to the size of the transport vehicle 2. The relative positions of the first crossbar 45 and the second crossbar 46 are adjusted. The first crossbar 45 and the second crossbar 46 are fixed by the second fastening pin 47 and the fastening nut 48, so that the two transport tracks 1 are fixedly connected together in the transverse direction.

[0049] A winding machine 31 is set up at a suitable position at the top of the slope. The transport vehicle 2 is connected to the winding machine 32 and positioned at the top of the slope. The transport vehicle 2 is loaded with transport materials. By loosening the winding machine 32, the transport vehicle 2 slides down the conveyor track 1 to the construction work surface. When it reaches the work position, the winding machine 31 stops winding, and the transport vehicle 2 stops at the completed substructure. At this time, the transport vehicle 2 approaches the construction position, and the materials on the transport vehicle 2 are manually moved and laid in the required position. As the laying operation proceeds, the transport vehicle 2 gradually slides down until the laying work of this section is completed.

[0050] When working from top to bottom, the winding machine 31 pulls the transport vehicle 2 up gradually, completing the laying of the working section in sequence.

[0051] When a section of the work is completed, the transport device is disassembled, and the above steps are repeated in the next section to complete the paving of the entire slope 7.

[0052] Throughout the process, workers do not need to move materials up and down slope 7; they only need to lay the materials from transport vehicle 2 at the work location onto slope 7 sequentially. Simultaneously, transport vehicle 2 can follow the work, improving work efficiency and saving manual labor.

[0053] In summary, the transportation device of this utility model, with two parallel conveyor tracks 1 arranged laterally at intervals and the transport vehicle 2 slidably mounted on them, combined with the drive mechanism 3, enables stable transportation of materials along the slope 7. Compared to manual handling, this significantly improves transportation efficiency, and compared to crane handling, it enhances safety and reliability. The lateral adjustment mechanism 4 can adjust the distance between the two conveyor tracks 1, adapting to different size requirements in various work scenarios, increasing the device's versatility, avoiding frequent equipment changes due to different work surfaces, and reducing costs. Furthermore, it can accommodate the size of the transport vehicle 2 and the volume of materials transported in a single trip.

[0054] The conveyor track 1 is composed of multiple track units 11 spliced ​​together, and adjacent track units 11 are detachably fixed by longitudinal connectors 5. It can be flexibly assembled according to the actual length of the slope 7, which improves the applicability of the device. At the same time, compared with the integral track, it is more convenient to maintain, and damaged track units 11 can be replaced individually, reducing maintenance costs. On the other hand, the slope protection needs to be laid sequentially along the transverse direction. When it is necessary to change the transport position, the detachable conveyor track 1 is easy to disassemble and reassemble, improving work efficiency.

[0055] Example 2: This example provides a different traveling wheel 24. Unlike Example 1, in this example, as shown... Figure 8 As shown, a mounting cavity 12 is provided in the middle of the conveying track 1, and longitudinally extending grooves 8 are provided on both transverse sides of the conveying track 1. The traveling wheel 24 includes a traveling block 9. Specifically, the lower end of the traveling block 9 is a constricted structure, and the upper end of the conveying track 1 is engaged in the constricted structure, which extends deep into the groove 8, allowing the traveling block 9 to slide longitudinally on the conveying track 1. In the inner cavity of the constricted structure, recesses 91 are respectively provided facing the upper end face of the groove 8 and the upper end face of the conveying track 1. A support wheel 92 is rotatably mounted in the recess 91, supporting the traveling block 9 on the conveying track 1 and reducing friction. The lower end of the vehicle body 21 is directly fixed to the traveling block 9. The traveling block 9 is used for limiting movement to prevent the transport vehicle 2 from derailing, and the rolling friction of the support wheel 92 facilitates the movement of the transport vehicle 2.

[0056] Example 3: This example provides a different travel wheel. Unlike Example 1, in this example, the track unit may not have a mounting cavity. In this case, the longitudinal connecting member is a connecting plate that is respectively set on both sides of the track unit in the transverse direction. The two ends of the connecting plate are respectively on the two track units. The connecting plate is connected and fixed to the two track units by bolt assembly.

[0057] Example 4: This example provides a different longitudinal connector. Unlike Example 1, in this example, to meet actual usage requirements, the longitudinal connector includes a central body whose dimensions are adapted to the dimensions of the track unit. Small-diameter sections are provided at both ends of the central body, and their dimensions are adapted to the dimensions of the mounting cavity, forming insertion sections. When the insertion sections on both sides are inserted into their corresponding mounting cavities, the two ends of the central body align with the opposite ends of the two track units, ensuring that the side facing away from the slope is flush and guaranteeing stable transport by the vehicle.

[0058] Example 5: This example provides a different driving mechanism. Unlike Example 1, in this example, when the transport vehicle is small, the single transport volume is small, and the driving force required to lower or raise the transport vehicle is small, a winding machine can be omitted to allow the transport vehicle to slide on the conveyor track by manually pulling a traction rope. Increasing the transport vehicle's speed also ensures operational efficiency. This configuration also limits the amount of lateral movement of workers on the slope during laying by reducing the single transport volume, further improving safety. Furthermore, without a winding machine, it is not necessary to repeatedly disassemble and reassemble the winding machine at the top of the slope when working on the next section, thus improving flexibility to some extent.

[0059] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0060] In the description of the embodiments of this application, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0061] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
