Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 shows a front view of a transport vehicle according to an embodiment of the invention, fig. 2 shows a top view of a transport vehicle according to an embodiment of the invention, and fig. 3 shows a right side view of a transport vehicle according to an embodiment of the invention.
The vehicle-mounted transmission device disclosed by the embodiment of the invention comprises a traction transmission guide rail 2 and a driving device 3.
The traction transmission guide rail of the embodiment of the invention has the most basic structure of comprising a driving wheel, a driven wheel and a traction piece; the driving wheel and the driven wheel are respectively arranged at the head part and the tail part of the carriage bottom plate; the traction piece is wound on the driving wheel and the driven wheel; in order to ensure that the container can be pulled by the pulling element, the top surface of the pulling element is higher than the carriage bottom plate.
In practice, in order to facilitate the installation of the traction elements, the driving wheels and the driven wheels and in view of the fact that the floor is used to support the traction elements, which are subject to wear, measures are generally taken to install traction internal guide tracks on the floor. When the traction inner guide rail is used as a mounting carrier of the driving wheel and the driven wheel and is worn by the traction piece and needs to be replaced, the whole carriage bottom plate does not need to be replaced, and the use cost is lower.
The traction inner guide rail longitudinally extends along the carriage, and the driving wheel and the driven wheel are arranged at two ends of the traction inner guide rail; the top surface of the traction inner guide rail is provided with a plane for placing the upper part of the traction piece; the upper part of the traction piece is placed on the top surface of the traction inner guide rail, and the lower part of the traction piece is positioned in the traction inner guide rail.
Fig. 4 shows a cross-sectional view of the traction conveyor rail 2. In the specific implementation, the cross section of the traction inner guide rail is provided with a plane for placing the upper part of the traction piece at the top, and the shapes of the rest positions can be any shape; in order to facilitate the installation of the traction inner guide rail, the carriage bottom plate can be provided with a groove matched with the traction inner guide rail for the installation of the traction inner guide rail.
In specific implementation, the traction member 303 can be a flexible traction member such as a transmission belt, a chain, a steel wire rope and the like, and can be provided with a fixed object such as a tray, a bracket, a plate and the like; .
The traction element 303 selected by the embodiment of the invention is a chain, and the driving wheel 304 and the driven wheel 305 which correspond to each other are a driving sprocket and a driven sprocket; the chain of the embodiment of the invention consists of the sleeve 307 and the chain plates 306, wherein two adjacent sleeve 307 are respectively arranged between two opposite chain plates 306, and the sleeve 307 can rotate around the installation axis of the sleeve 307; in particular implementations, the link plates 306 are further divided into outer link plates and inner link plates; the outer link plates and the inner link plates are alternately arranged and connected based on the rotation shaft of the sleeve 307; the outer link plate and the inner link plate are movable about the rotational axis of the sleeve 307; because the structure of the chain is relatively common, the embodiment of the invention is not described in more detail.
The traction member 303 is wound around the driving wheel 304 and the driven wheel 305, and when the driving wheel 304 and the driven wheel 305 are mounted on the carriage bottom plate, the upper part of the traction member is placed on the top surface of the carriage; when the driving pulley 304 and the driven pulley 305 are mounted on the traction inner rail, the upper portion of the traction member is placed on the top surface of the traction inner rail. The traction element 303 adopted by the embodiment of the invention is a chain, so the driving wheel 304 and the driven wheel 305 are a driving sprocket and a driven sprocket matched with the chain, wherein the driving sprocket driven by the driving device 3 is a driven sprocket which is not driven by the driving device 3; the upper part of the chain is pressed on the carriage bottom plate or the traction inner guide rail under the action of gravity, and two sides of the chain are wound into the traction inner guide rail 301 through a driving chain wheel and a driven chain wheel respectively.
In a specific implementation, in order to further reduce the maintenance cost of the vehicle-mounted transmission device, a fixed conducting bar can be installed on the surface of the traction inner guide rail 301 or the surface of the carriage bottom plate, and the conducting bar is most preferably made of a material with higher wear resistance; when wear occurs, the replacement cost of the guideline is much lower than the cost of the traction inner guideline and the floor.
In specific implementation, aiming at the structural characteristics of the chain, the following design is made on the supporting surface of the supporting chain, so that the motion resistance of the chain can be effectively reduced, the transverse position of the chain is limited, the durability of the chain and the parts for supporting the chain is improved, and the maintenance cost of the vehicle-mounted transmission equipment is reduced: on one hand, the supporting surface is provided with a bulge with the width smaller than the distance between two opposite chain plates; the bulges are positioned between two opposite chain plates and are propped against the sleeve of the chain, and the chain is transversely clamped between the chain plates; since the sleeve 307 is rotatable about its own axis, the running resistance of the chain is small; on the other hand, the lower end of the link plate should not contact the supporting surface to reduce frictional resistance. The wear-resistant guide bar 302 of the embodiment of the invention is provided with a protrusion 308 with a width smaller than that of the two opposite chain plates 306; the protrusions 308 are located between two opposite link plates 306 and bear against the bushings 307, and the lower ends of the link plates 306 are not in contact with the wear bars 302.
The driving device 3 is arranged at one end of the traction transmission guide rail 2, and is connected with the traction transmission guide rail to form a driving wheel. Since the traction element 303 is required to be driven by the driving wheel 304 in the embodiment of the present invention, the circumferential motion of the driving wheel 304 is converted into the translational motion of the traction element 303, and therefore, the driving device 3 should be selected as the rotation driving device 3; in a specific implementation, the driving device 3 may be a motor, a hydraulic pump or the like, and the driving device 3 and the driving wheel may be connected directly or indirectly through a belt, a sprocket or the like. The driving device 3 of the embodiment of the invention adopts a gear motor; wherein, the front view of the transport vehicle of fig. 1 shows a schematic structure when an indirect connection mode is adopted, and the driving device 3 is connected to the driving wheel through a chain and drives the driving wheel to rotate; the top view of the transport vehicle of fig. 2 shows a schematic structural diagram when a direct connection mode is adopted, the driving wheel 304 is directly installed on the rotating shaft of the driving device 3, and the driving device 3 rotates to drive the driving wheel 304 to move; since the reduction gear unit is configured differently in the case of direct connection and indirect connection for the sake of clarity, the front view of the transporter shown in fig. 1 is different from the top view of the transporter shown in fig. 2 with respect to the partial configuration of the drive unit 3.
In the embodiment of the present invention, by controlling the driving device 3, it is possible to control the movement of the upper portion of the traction member 303 toward the head or tail of the vehicle compartment 1, thereby controlling the movement of the container 6 thereon toward the head or tail of the vehicle compartment 1.
When the driving wheel, the driven wheel and the traction piece are adopted as the parts for driving the container 6 to move, a certain tension is required to be maintained on the traction piece between the driving wheel and the driven wheel in order to ensure that the driving force of the driving device 3 can be transmitted to the traction piece through the driving wheel; therefore, a set of tensioning mechanisms is required to achieve this. The tensioning mechanism can be arranged on the carriage bottom plate or on the traction inner guide rail.
Fig. 8 shows a top view of a tensioning mechanism according to an embodiment of the invention.
The tensioning mechanism of the embodiment of the present invention includes a tail shaft 805 and two sets of adjustment devices;
On the two vertically opposite surfaces of the traction inner rail 301, long waist through holes in the longitudinal direction are symmetrically formed; the adjusting device comprises a connecting plate 803 fixed on the long-waist through hole based on a bolt 804, a screw mounting block 802 for adjusting the fixed position between the connecting plate 803 and the long-waist through hole, and a screw 801; a screw mounting block 802 is fixed on one side of the longitudinal direction of the long waist through hole, and a screw 801 passes through the screw mounting block 802 and is connected to the connecting plate 803; the two groups of adjusting devices are symmetrically arranged outside two vertical opposite surfaces of the traction inner guide rail 301; two ends of a tail shaft 805 are respectively mounted on the two mounting plates 803, and the driven wheel 305 is fixed on the tail shaft. By adjusting the position of the screw 801 on the screw mounting block 802, the connection plate 803 can be driven to move in the longitudinal direction, driving the movement of the tail shaft 805 and the driven wheel 305, thereby achieving tensioning and loosening of the bar.
In the concrete implementation, the container 6 can be driven to longitudinally move by arranging a single traction transmission guide rail 2; however, in order to ensure the balance of the movement of the container 6, the transverse dimension of the traction transmission guide rail 2 needs to be increased, and the cost is high based on the cost consideration; therefore, in order to balance the movement of the container 6, the roller conveyor rail 5 is installed on the side of the traction conveyor rail 2.
The roller conveyor rail 5 comprises at least one roller, the axis of which should be parallel to the axis of the driving wheel and the height of the top generatrix should be level with the top surface of the traction element.
In order to facilitate the installation of the roller and reduce the installation cost, in a specific implementation, a traction inner guide rail longitudinally arranged along the carriage can be arranged; the roller is arranged on the traction inner guide rail;
In order to facilitate the installation of the traction inner guide rail, a groove matched with the traction inner guide rail can be arranged on the carriage bottom plate.
Fig. 6 shows a schematic cross-sectional view of a roller conveyor rail according to an embodiment of the invention. The roller conveyor rail 5 of the present embodiment includes an inner roller rail 501 extending longitudinally along the corresponding recess 202 and rollers 502 capable of rolling about an axis.
The roller 502 is horizontally and transversely arranged on two opposite vertical surfaces of the roller inner guide rail 501, and the top bus is higher than the roller inner guide rail 501; the axes of the rollers 502 on the same roller conveyor rail 5 are parallel to each other and the top generatrix lies in the same plane to ensure that each roller 502 is in contact with the container 6 and to provide support.
To ensure that the rollers 502 and the traction members 303 support the container 6 at the same time, the top bus of the rollers 502 is level with the top surface of the traction members 303 to ensure simultaneous contact with the container 6.
It should be noted that in order to ensure that the container 6 can move in the direction of the movement of the traction element, the axis of the drum should be perpendicular to the traction element; i.e. the traction conveyor rail 2 should be parallel to the roller conveyor rail.
In order to enable the container 6 to move inside the carriage 1 more smoothly, two or more roller conveying guide rails can be arranged; the roller transmission guide rails are respectively arranged at two sides of the traction transmission guide rail 2 so as to achieve a better balance effect.
In particular, if the container 6 is supported by the traction and transport rail 2 at all times, or by the traction and transport rail 2 and the drum transport rail, a great pressure load is caused to the traction members of the traction and transport rail 2, the driving wheel, the driven wheel and the rotation shaft of the drum transport rail, which is disadvantageous for long-term use of the traction and transport rail 2 and the drum transport rail. Therefore, in order to avoid the occurrence of the above situation, the pallet container 6 can be prevented from being pressed on the traction transmission guide rail 2 and the roller transmission guide rail for a long time by lowering the traction transmission guide rail 2 and the roller transmission guide rail below the bottom plate 201 of the carriage 1 during the transportation of the transport vehicle, and providing the pallet container 6 with the bottom plate 201 of the carriage 1; therefore, in the embodiment of the invention, the vehicle-mounted transmission device further comprises a jacking device.
The jacking device is mainly used for controlling the traction transmission guide rail 2 and the rolling transmission guide rail to move in the vertical direction, and when the carriage 1 needs to be loaded or unloaded, the jacking device stretches out of the bottom plate 201 of the carriage 1 to jack up the container 6 from the bottom plate 201 of the carriage 1 for conveying; when loading or unloading of the compartment 1 is completed, the compartment 1 is lowered below the floor 201 of the compartment 1, and the floor 201 of the compartment 1 provides a supporting force for the container 6.
In specific implementation, the jacking device can be a hydraulic cylinder, a lifting air bag and other driving devices 3, and the hydraulic cylinder is simple in structure and reliable in operation, so that a speed reducing device can be omitted when the hydraulic cylinder is used for realizing reciprocating motion, a transmission gap is avoided, the motion is stable, and the use scene of the vehicle-mounted transmission equipment in the embodiment is relatively met. The jacking device of the embodiment of the invention is fixed below the traction transmission guide rail 2 and the roller transmission guide rail, and the output end is respectively connected with the traction inner guide rail and the roller inner guide rail; when the hydraulic cylinder is used as a jacking device, the hydraulic cylinder body is fixed on the carriage 1, and the push rod is connected with the traction inner guide rail and the roller inner guide rail.
Fig. 4 shows a sectional view of the traction transport rail 2 in a lifted state, and fig. 6 shows a sectional view of the drum transport rail in a lifted state. When the jacking device is raised to a high position, the traction member surface and the top bus of the drum need to be higher than the floor 201 of the carriage 1 and are level to ensure that sufficient friction and support force are provided to the container 6;
Fig. 5 shows a sectional view of the traction transport rail 2 in a dropped state, and fig. 7 shows a sectional view of the roller transport rail in a dropped state. When the jacking means is lowered to a lowered position, the traction element surface and the top busbar of the drum need to be lower than the floor 201 of the car 1 to ensure that the container 6 falls onto the floor 201 of the car 1, providing support by means of the floor 201 of the car 1.
In specific implementation, the same jacking device can be used for driving the vertical movement of the traction conveying guide rail 2 and the roller conveying guide rail; multiple jacking devices may also be employed to drive the vertical movement of the traction transport rail 2 and the roller transport rail, respectively.
Fig. 9 shows a schematic view of the limit structure of the traction inner rail, the drum inner rail and the outer rail. Considering that during the movement of the container 6, the traction conveyor rail and the roller conveyor rail will receive forces in the longitudinal direction; in order to maintain the positions of the traction transmission guide rail and the roller transmission guide rail in the longitudinal direction, an outer guide rail 601 is arranged outside the traction inner guide rail and the roller inner guide rail; the inner wall of the outer guide rail 601 is provided with a clamping block 902 for clamping, and the peripheries of the traction inner guide rail and the outer periphery of the inner guide rail of the roller are provided with a matching clamping block 901 for matching clamping; the matching clamping blocks 901 are clamped between two adjacent clamping blocks 902, so that the purposes of longitudinal limiting and no influence on the vertical movement of the traction inner guide rail and the roller inner guide rail are achieved.
In practice, the number of traction transport rails 2 and roller transport rails is designed according to the weight, size of the container 6, and the like.
In the embodiment of the invention, the two traction and transmission guide rails 2 and four roller transmission guide rails are provided, the four roller transmission guide rails are respectively arranged at two sides of the two traction and transmission guide rails 2, and at most, two rows of container containers 6 can be transported at the same time.
In order to realize automatic control of loading and unloading of the carriage 1, a control box based on PLC is arranged on the carriage 1 shell of the embodiment of the invention, and three groups of sensors are respectively arranged on the inner walls of two vertical opposite surfaces of the carriage 1; the first group of sensors includes a first sensor 1001 and a second sensor 1002, mounted between the head and tail of the vehicle cabin 1; the second group of sensors includes a third sensor 1003 and a fourth sensor 1004, mounted to the cabin head; the third set of sensors includes a fifth sensor 1005 and a sixth sensor 1006 mounted on the rear of the vehicle cabin.
The first group of sensors, namely the first sensor 1001 and the second sensor 1002 in the embodiment of the present invention, are used for sensing the position of the container 6 when the container 6 is loaded, in order to ensure that the container 6 can be stably located on the carriage 1 after being removed from the carrying device such as a forklift and a transportation rail, and cannot fall from the tail of the carriage 1, in a specific implementation, the first sensor 1001 and the second sensor 1002 have at least one half of the length of the container 6 from the tail of the carriage 1, so as to ensure that the center of gravity can fall inside the carriage 1 when the container 6 triggers the first sensor 1001 and the second sensor 1002 at the same time; when the container 6 triggers the first sensor 1001 and the second sensor 1002 at the same time, the handling equipment such as a forklift and a transport rail can be removed, and the container 6 can be stabilized inside the carriage 1 and cannot fall.
The second set of sensors, the third sensor 1003 and the fourth sensor 1004 of the embodiment of the present invention, are used to sense whether the container 6 has been filled in the car 1; since the third sensor 1003 and the fourth sensor 1004 are provided at the head of the car 1, when the head of the car 1 senses the container 6, it means that the container 6 has filled the car 1, and the loading should be stopped.
A third set of sensors, namely a fifth sensor 1005 and a sixth sensor 1006 of the present embodiment, senses whether the container 6 reaches the rear of the car 1 when the container is unloaded; when the fifth sensor 1005 or the sixth sensor 1006 is triggered by the container 6, it means that the container 6 has reached the rear of the vehicle cabin 1, and a handling device such as a forklift or a matched transportation rail is required to remove the container 6 located at the rear of the vehicle cabin 1 from the vehicle cabin 1.
The first sensor 1001, the second sensor 1002, the third sensor 1003, the fourth sensor 1004, the fifth sensor 1005, and the sixth sensor 1006 are respectively connected to the PLC, and transmit a trigger signal to the PLC; the driving device 3 and the jacking device are connected with and controlled by a PLC, and the PLC realizes automation of loading and unloading by controlling the movement of the driving device 3 and the jacking device based on the received trigger signal and manual control.
