Description

Technical Field

[0001] This application belongs to the field of underground auxiliary transportation technology in coal mines, specifically relating to a rubber-tired vehicle carriage for securing containers. Background Technology

[0002] The auxiliary transportation system for underground materials in coal mines is a crucial artery for maintaining normal production and efficient operation. Its performance directly affects the advance speed of the mining face, equipment supply guarantee, and overall production efficiency. With the expansion of mining scale and the increase in intensification, the types and quantities of materials that need to be transported underground are numerous and vast, including support materials, equipment parts, and production consumables. This places higher demands on the carrying capacity, transfer efficiency, and adaptability of the transportation system.

[0003] In existing technologies, underground material transfer is mainly carried out using monorail cranes and rubber-tired transport vehicles. For bulk, lightweight materials, they are usually first loaded into standard containers before being transported using the aforementioned equipment. Among these, monorail cranes are commonly used for transporting containers, as they carry containers by lifting them.

[0004] However, using monorail cranes to transport containers has significant drawbacks, including slow operating speed, high personnel requirements, and low transportation efficiency, making it difficult to meet the urgent needs of efficient underground production. Meanwhile, although rubber-tired vehicles offer a speed advantage, their ordinary carriage structure lacks dedicated limiting and securing devices, making it impossible to safely and reliably carry and secure containers, posing significant transportation safety hazards. This prevents the speed advantage of rubber-tired vehicles from being effectively utilized in container transportation scenarios. Utility Model Content

[0005] This application provides a rubber-tired vehicle carriage for securing containers, in order to solve the technical problems of low efficiency in transporting containers by existing monorail cranes, and the safety hazards and inability to take advantage of speed of ordinary rubber-tired vehicles due to the lack of dedicated securing devices.

[0006] To achieve the above objectives, this application provides a rubber-tired vehicle body for securing containers, comprising:

[0007] The rubber-tired wagon body forms the space for accommodating the container; the four sides of the container are each equipped with a first connecting lug.

[0014] Preferably, a plurality of first positioning holes are evenly spaced along the extension direction of the slide rail;

[0015] A second positioning hole corresponding to the first positioning hole is provided at both ends of the slider;

[0016] The second limiting member is fixed to different preset positions on the floor of the rubber-tired vehicle body by inserting a pin into the first positioning hole and the second positioning hole in sequence.

[0017] Preferably, both ends of the slide rail are provided with stop blocks.

[0018] Preferably, a first connecting hole is provided on the first connecting ear, and a second connecting hole corresponding to the first connecting hole is provided on the second connecting ear.

[0019] Preferably, the fastener includes a bolt and a nut; the bolt passes through the first connecting hole and the second connecting hole in sequence, and the bolt shank extends out of the first connecting hole and the second connecting hole and is then locked in place by double nuts.

[0020] Preferably, a cushioning pad is provided on the contact surface between the first limiting member and / or the second limiting member and the container.

[0021] Preferably, a first reinforcing rib is provided between the second limiting member and the floor plate of the rubber-tired vehicle body.

[0022] Preferably, a second reinforcing rib is provided between the second connecting ear and the first limiting member and the second limiting member respectively.

[0023] This application provides a rubber-tired vehicle body for securing a container, comprising a rubber-tired vehicle body that forms a space for accommodating the container; a first limiting member and a second limiting member are disposed opposite to each other at both ends of the floor plate of the rubber-tired vehicle body; the second limiting member is slidably disposed on the floor plate of the rubber-tired vehicle body; a second connecting lug is disposed at both ends of the first limiting member and the second limiting member; the four side faces of the container are respectively provided with the first connecting lug; when the container is placed in the rubber-tired vehicle body, the two ends of the bottom surface of the container are respectively abutted against the first limiting member and the second limiting member, the second connecting lug is inserted into the first connecting lug, and the first connecting lug and the second connecting lug are detachably connected by fasteners. This application provides support and restraint for the container through the oppositely disposed first limiting member and the second limiting member, wherein the slidable design of the second limiting member allows the rubber-tired vehicle body to accommodate containers of different lengths; at the same time, the reliable fixation of the container to the rubber-tired vehicle body is achieved through the interlocking first connecting lug and the second connecting lug structure and the fastener connection.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the protection scope of this application.

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0034] Furthermore, in this application, directional terms such as "upper," "lower," "inner," and "outer" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0035] In modern mine production systems, material transportation efficiency directly restricts the continuity of mining operations and the release of overall production capacity. With the continuous extension of underground working faces and the increasing size of equipment, the transfer capacity of bulk materials such as support materials and hydraulic supports faces even more severe challenges. An efficient and reliable auxiliary transportation system has become an indispensable key link in ensuring intensive mine production.

[0036] Currently, containerized operations are commonly used in underground bulk material transportation, primarily relying on two types of equipment: monorail systems and trackless rubber-tired vehicles. Monorail locomotives, as a traditional mode of transportation, transport containers by suspending them on overhead rails, offering the advantage of being unaffected by floor conditions. Meanwhile, ordinary rubber-tired vehicles, with their flexible maneuverability and high speed, play a role in certain material transportation scenarios.

[0037] However, both existing transportation methods have significant limitations. Monorail systems, constrained by track layout and operating mechanisms, have lower average transport speeds and more complex scheduling processes, making them difficult to meet the demands of high-efficiency production. While conventional rubber-tired vehicles offer speed advantages, their flatbed structure lacks a secure mechanism for containers, failing to effectively limit container displacement during vehicle start-up, stopping, and cornering. This poses safety hazards such as slippage and collisions, preventing rubber-tired vehicles from fully realizing their potential in container transport operations.

[0038] To address the aforementioned problems, this application provides a rubber-tired vehicle body for securing containers, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 3 ,include:

[0039] The rubber-tired wagon compartment 1 forms the carrying space for accommodating standard containers. The rubber-tired wagon compartment 1 adopts the standard flatbed structure of a mining explosion-proof rubber-tired wagon.

[0040] Each of the four side facades of container 2 is provided with a first connecting lug 3. The first connecting lug 3 is made of metal sheet with connecting holes and is fixed to the side facade of container 2 by welding.

[0041] The first limiting member 4 is fixedly installed on the floor plate of the rubber-tired vehicle body 1. The first limiting member 4 is made of channel steel and extends perpendicular to the longitudinal centerline of the rubber-tired vehicle body 1. The first limiting member 4 is connected to the floor plate of the rubber-tired vehicle body 1 by welding. The first limiting member 4 is located at one end of the longitudinal direction of the rubber-tired vehicle body 1 and is used to support one end of the bottom surface of the container 2.

[0042] The second limiting member 5 is slidably mounted on the floor of the rubber-tired vehicle body 1. The second limiting member 5 is made of channel steel and extends perpendicular to the longitudinal centerline of the rubber-tired vehicle body 1. The second limiting member 5 is located at the other end of the longitudinal direction of the rubber-tired vehicle body 1, opposite to the first limiting member 4. The second limiting member 5 is used to support the other end of the bottom surface of the container 2.

[0043] The second connecting ear 6 is disposed at both ends of the first limiting member 4 and both ends of the second limiting member 5. The second connecting ear 6 is made of metal sheet with connecting holes. The second connecting ear 6 is fixedly connected to the first limiting member 4 and the second limiting member 5 respectively by welding.

[0044] Understandably, when transporting container 2, the operator first adjusts the position of the second limiting member 5 on the floor of the rubber-tired truck body 1, ensuring the distance between the first limiting member 4 and the second limiting member 5 is compatible with the length of container 2. The operator then uses underground hoisting equipment to lift container 2 onto the floor of the rubber-tired truck body 1, ensuring that both ends of the bottom surface of container 2 are aligned with the upper surfaces of the first limiting member 4 and the second limiting member 5, respectively. At this point, the second connecting lug 6 is inserted into the first connecting lug 3, and the operator uses fasteners to connect and secure the first connecting lug 3 and the second connecting lug 6, completing the overall fixation of container 2 within the rubber-tired truck body 1.

[0045] In this embodiment, the rubber-tired carriage 1 provides the carrying space for the container 2. The first limiting member 4 and the second limiting member 5 cooperate to support the bottom surface of the container 2. The sliding design of the second limiting member 5 allows the rubber-tired carriage 1 to adapt to containers 2 of different sizes. The second connecting lug 6 is connected to the first connecting lug 3 through a plug-in structure and fasteners to fix the container 2. The rubber-tired carriage 1 can safely and reliably undertake the transportation task of the container 2, fully meeting the actual needs of rapid transportation of light and bulk materials in underground coal mines.

[0046] In some embodiments, see Figure 2 and Figure 4 The slider 7 is fixedly mounted at both ends of the bottom of the second limiting member 5. The slide rail 8 is fixedly mounted on opposite sides of the bottom plate of the rubber-tired vehicle body 1. The extending direction of the slide rail 8 is parallel to the longitudinal centerline of the rubber-tired vehicle body 1. The slide rail 8 and the slider 7 cooperate with each other to form the sliding guide mechanism of the second limiting member 5. The second limiting member 5 moves longitudinally on the slide rail 8 via the slider 7, thereby adjusting the distance between the second limiting member 5 and the first limiting member 4.

[0047] Understandably, when it is necessary to accommodate containers of different lengths, the operator pushes the second limiting member 5 to move longitudinally along the slide rail 8. The slider 7 slides smoothly under the guidance of the slide rail 8, so that the distance between the first limiting member 4 and the second limiting member 5 matches the length of the container.

[0048] In this embodiment, the sliding engagement of the slider 7 and the slide rail 8 enables the second limiting member 5 to have a longitudinal position adjustment function. The slider 7 is located at both ends of the bottom of the second limiting member 5, and the slide rail 8 is correspondingly located on both sides of the carriage floor. This symmetrical arrangement ensures the stability of the second limiting member 5 during movement. This design enables a single carriage to adapt to containers of various specifications, effectively improving the versatility and efficiency of the rubber-tired carriage 1.

[0049] In some embodiments, see Figure 5The slide rail 8 is provided with first positioning holes 81, which are evenly spaced along the extension direction of the slide rail 8. The first positioning holes 81 are through holes, and their diameter matches the diameter of the rod of the pin 9. The function of the first positioning holes 81 is to provide multiple fixing points, allowing the second limiting member 5 to be fixed at a preset position on the slide rail 8.

[0050] The slider 7 has a second positioning hole 71 at each end. The second positioning hole 71 is a through hole structure, and the diameter of the second positioning hole 71 matches the diameter of the rod of the pin 9. The position of the second positioning hole 71 corresponds to the position of the first positioning hole 81. When the slider 7 moves along the slide rail 8, the second positioning hole 71 can be aligned with the first positioning hole 81 at different positions.

[0051] The pin 9 passes sequentially through the second positioning hole 71 and the first positioning hole 81. One end of the pin 9 can be provided with a handle or a ring-shaped structure for easy gripping and operation. When the pin 9 passes through both the second positioning hole 71 and the first positioning hole 81 simultaneously, the second limiting member 5 remains relatively fixed to the slide rail 8. When the pin 9 is removed from the first positioning hole 81 and the second positioning hole 71, the second limiting member 5 can move longitudinally along the slide rail 8 via the slider 7.

[0052] Understandably, during actual operation, when the position of the second limiting member 5 needs to be adjusted, the operator removes the pin 9 from the first positioning hole 81 and the second positioning hole 71. The second limiting member 5 is then moved along the slide rail 8 to the target position, aligning the second positioning hole 71 on the second limiting member 5 with the target first positioning hole 81 on the slide rail 8. The pin 9 is then inserted into the aligned second positioning hole 71 and the target first positioning hole 81, completing the positioning and fixing of the second limiting member 5.

[0053] In this embodiment, the first positioning hole 81 on the slide rail 8, the second positioning hole 71 on the slider 7, and the pin 9 work together to allow the second limiting member 5 to be fixed at different preset positions on the slide rail 8. This arrangement can adapt to the fixing requirements of containers 2 of different sizes, effectively reducing the time required for adjustment. The structure composed of the slide rail 8, slider 7, and pin 9 is practical, convenient, and reliable in operation, ensuring that the second limiting member 5 maintains a stable working position during transportation, meeting the requirements of underground material transportation.

[0054] In some embodiments, see Figure 2The stop blocks 82 are fixedly installed at both ends of the slide rail 8. When the slider 7 moves along the slide rail 8 to the end of the slide rail 8, the stop blocks 82 contact the end face of the slider 7 and form a mechanical block, preventing the slider 7 from moving forward. This blocking effect effectively prevents the slider 7 from accidentally dislodging from the slide rail 8, ensuring that the second limiting member 5 always works within the set stroke range. The stop blocks 82 are firmly connected to the slide rail 8 by welding, possessing high structural strength and reliability, and providing safety protection for the sliding fit structure between the slider 7 and the slide rail 8.

[0055] In some embodiments, see Figure 2 and Figure 3 The first connecting ear 3 is provided with two first connecting holes 31. Both first connecting holes 31 are through holes and are symmetrically arranged on both sides of the ear plate of the first connecting ear 3.

[0056] The second connecting ear 6 is provided with two second connecting holes 61. Both second connecting holes 61 are through holes and are symmetrically arranged on both sides of the ear plate of the second connecting ear 6.

[0057] The positions of the second connecting holes 61 correspond one-to-one with the positions of the first connecting holes 31. When the second connecting ear 6 is inserted into the first connecting ear 3, the central axis of each second connecting hole 61 coincides with the central axis of the corresponding first connecting hole 31.

[0058] This embodiment provides a structural basis for the two-point connection and fixation of the first connecting ear 3 and the second connecting ear 6 by providing two first connecting holes 31 on the first connecting ear 3 and two second connecting holes 61 corresponding to the first connecting holes 31 on the second connecting ear 6. The corresponding arrangement of the first connecting holes 31 and the second connecting holes 61 ensures the accuracy of the connection position and creates conditions for the reliable connection of the fasteners.

[0059] In some embodiments, see Figure 1 Each first connecting lug 3 is connected to its corresponding second connecting lug 6 by a set of fasteners. This set of fasteners includes one bolt and two nuts. The diameter of the bolt shank matches the diameter of the first connecting hole 31 and the second connecting hole 61.

[0060] After the second connecting lug 6 is inserted into the first connecting lug 3 and the second connecting hole 61 is aligned with the first connecting hole 31, the operator inserts the bolt through the first connecting hole 31 and the second connecting hole 61 in sequence. Both ends of the bolt shank protrude from the outer surfaces of both sides of the first connecting lug 3. A nut is installed at each end of the bolt shank. The two nuts contact the two outer surfaces of the first connecting lug 3, respectively. The operator uses a tool to tighten the two nuts towards each other, completing the fixed connection between the first connecting lug 3 and the second connecting lug 6.

[0061] This embodiment achieves a detachable connection between the two connecting ears by using bolts and nuts at the connection points of each first connecting ear 3 and second connecting ear 6. This connection method facilitates installation and disassembly, providing convenience for the loading and unloading operations of container 2.

[0062] In some embodiments, see Figure 2 A buffer pad 10 is provided on the contact surface between the first limiting member 4 and the second limiting member 5 and the container 2. The buffer pad 10 is installed on the surface of the limiting member by adhesive or mechanical fixing.

[0063] Understandably, during transportation, the elastic properties of the cushioning pad 10 can mitigate vibration transmission between the container 2 and the limiting components, reducing collision wear between them. The frictional force generated between the cushioning pad 10 and the bottom surface of the container 2 helps to suppress slight displacement of the container 2.

[0064] This embodiment solves the problem of collision and wear between the first limiting member 4 and the second limiting member 5 and the container 2 by setting a buffer pad 10 on the contact surface of the first limiting member 4 and the second limiting member 5. At the same time, the elastic deformation and friction characteristics of the buffer pad 10 are used to reduce the slight displacement of the container during transportation bumps and further improve the fixation stability.

[0065] In some embodiments, see Figure 2 A first reinforcing rib plate 11 is provided between the second limiting member 5 and the bottom plate of the rubber-tired vehicle body 1. The first reinforcing rib plate 11 is made of triangular steel plate and is firmly connected to both the second limiting member 5 and the bottom plate of the rubber-tired vehicle body 1 by welding.

[0066] A second reinforcing rib plate 12 is provided between the second connecting ear 6 and the first limiting member 4 and the second limiting member 5 respectively. The second reinforcing rib plate 12 is made of triangular steel plate and is firmly connected to the second connecting ear 6, the first limiting member 4 and the second limiting member 5 by welding.

[0067] This embodiment forms a multi-reinforcement structure by providing a first reinforcing rib plate 11 between the second limiting member 5 and the floor of the carriage, and a second reinforcing rib plate 12 between the second connecting ear 6 and the first limiting member 4, and between the second connecting ear 6 and the second limiting member 5. The first reinforcing rib plate 11 enhances the connection strength between the second limiting member 5 and the floor of the rubber-tired carriage 1, while the second reinforcing rib plate 12 enhances the connection strength between the second connecting ear 6 and the first limiting member 4, and between the second connecting ear 6 and the second limiting member 5. The first reinforcing rib plate 11 and the second reinforcing rib plate 12 improve the structural stability and load-bearing capacity of the rubber-tired carriage used to fix the container, ensuring that the device maintains reliable operation under long-term heavy-load conditions.

[0068] This application provides a rubber-tired vehicle body for securing a container, comprising a rubber-tired vehicle body 1, which forms a space for accommodating a container 2. A first limiting member 4 and a second limiting member 5 are disposed opposite each other at both ends of the bottom plate of the rubber-tired vehicle body 1, wherein the second limiting member 5 is slidably disposed on the bottom plate. Second connecting ears 6 are respectively provided at both ends of the first limiting member 4 and the second limiting member 5. First connecting ears 3 are respectively provided on the four side facades of the container 2. When the container 2 is placed inside the rubber-tired vehicle body 1, both ends of the bottom surface of the container 2 are respectively abutted against the first limiting member 4 and the second limiting member 5, and the second connecting ears 6 are inserted into the first connecting ears 3. The first connecting ears 3 and the second connecting ears 6 are detachably connected by fasteners. This rubber-tired vehicle body has a simple structure and is easy to operate, allowing for rapid securing and disassembly of the container 2 without modification.
