Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely a few embodiments of the invention and are not to be taken as a comprehensive embodiment. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.

Example (b):

as shown in fig. 10, urban underground logistics vehicles operate in underground pipelines, and drainage ditches for removing sewage or accumulated water are usually provided in the pipelines. The present invention uses the roof of the drain as the running surface 291 and the side walls of the drain as the guide surface 292.

The invention provides an underground logistics vehicle, which comprises a vehicle frame 100, a bogie 200 and a conveying clamping device 300, as shown in figures 1 to 13. As shown in fig. 3 to 5, the vehicle frame 100 includes a frame structure formed by connecting an under frame, a pillar, and a top frame to each other. Specifically, the underframe includes a main beam 111, a sub-beam 112, and a bottom plate 113, and the main beam 111 is disposed at a middle portion of the bottom of the frame 100 along the longitudinal direction of the frame 100. The plurality of secondary beams 112 are respectively connected with the main beam 111 along the width direction of the frame 100 by welding or bolting, and the plurality of secondary beams 112 are arranged at intervals along the length direction of the main beam 111. The main beam 111 is flush with the upper surface of the secondary beam 112 after being connected, and the bottom plate 113 is connected to the upper surfaces of the main beam 111 and the secondary beam 112 by welding or bolting.

The main beam 111 may be made of i-steel, channel steel, or composite steel. The secondary beam 112 may be a variable cross-section beam, and the cross-sectional area of the root of the secondary beam 112 is larger than that of the end. Of course, the structure of the underframe with a plurality of longitudinal and transverse beams may be selected according to the specific span of the frame 100. The frame 100 may also be designed with an open top configuration depending on the type of cargo being transported.

As shown in fig. 3 to 5, the upright post includes a corner post 114 and a side post 115. The four corner posts 114 are connected to four corners of the bottom frame by welding or bolting, and the side post 115 is disposed on the bottom frame between the two corner posts 114 along the length direction of the frame 100. The upright post can be made of I-shaped steel, channel steel or combined section steel and the like.

As shown in fig. 3 to 5, the top frame includes a longitudinal beam 116, a transverse beam 117, and a top plate 118, two ends of the longitudinal beam 116 and the transverse beam 117 are respectively connected to the tops of the columns by welding or bolting, and the top plate 118 is connected to the longitudinal beam 116 and the transverse beam 117 by welding or bolting. The longitudinal beams 116 and the transverse beams 117 can be made of rectangular pipes. In order to enhance the rigidity of the top of the frame 100, a reinforcing plate 119 is connected between the pillars by welding or bolting, and one side of the reinforcing plate 119 is connected to the top frame.

As shown in fig. 1 to 5, two end brackets 120 are respectively disposed at both ends of the frame 100 along the length direction of the frame 100 for connecting with the bogie 200. Specifically, the end bracket 120 includes two end support beams 121 having an L-shaped cross section, and the short side of each end support beam 121 is connected to the corresponding corner post 114 and the secondary beam 112 by welding or bolting.

The long side of each end bolster 121 and the arc transition between the corresponding corner post 114 and the secondary beam 112 are in a structure of adduction so as to avoid the interference between the end bolster 121 and the wheel. An end bearing plate 122 is connected between the two end bearing beams 121 by welding or bolt connection, and an adduction structure with arc transition is also formed between the end bearing plate 122 and the corresponding secondary beam 112. The end bearing plate 122 cooperates with the two end bearers 121 to form an end bearer 120 that is attached to the truck 200.

As shown in fig. 1-5, it is noted that the height of the bottom surface of the end bolster 120 is greater than the height of the bottom surface of the vehicle frame 100, i.e., the bottom of the end bolster 121 is higher than the top of the underframe. When the end bracket 120 is attached to the truck 200, the entire frame 100 is formed with a concave configuration. The top frame of the frame 100 is lowered due to the raised height of the end support frame 120, and when the cross sections of the pipelines are the same in size and the length of the vehicle is the same, the height of the upright column can be increased, so that the top frame of the frame 100 is further raised relative to the existing frame 100, the purpose of increasing the volume of the vehicle is achieved, the transportation efficiency of the vehicle is greatly improved, and the construction cost of the pipelines is reduced. Compared with the existing frame, the frame of the invention can increase the volume of the vehicle by at least 30 percent.

It will be appreciated that the manner in which the end bracket 120 is attached to the vehicle frame 100 will vary depending on the configuration of the vehicle frame 100. For example, for a vehicle frame 100 having a headwall configuration, the end bolster 120 may be directly connected to the headwall. For the frame 100 without the end wall structure, a cross beam may be added between the two corner posts 114 at the end wall position, so that the end support frame 120 is connected with the cross beam, the secondary beam 112 and the two corner posts 114 respectively, so as to ensure the reliability of the connection of the end support frame 120.

Of course, the elevation of the end support 120 relative to the undercarriage may be determined based on the actual distance between the undercarriage of the frame 100 and the ground after the end support 120 is attached to the truck 200.

As shown in fig. 1 to 5, in order to facilitate connection between the end bearing frame 120 and the bogie 200, a spring seat 123 corresponding to a position of a spring assembly 250 on the bogie 200 is provided at a bottom of the end bearing beam 121, a first damping seat 124 corresponding to a position of a damper 280 on the bogie 200 is provided at a top lower surface of the end bearing beam 121, and the end bearing frame 120 is connected to the bogie 200 through the spring seat 123 and the first damping seat 124, respectively.

As shown in fig. 1 to 5, in order to facilitate connection between adjacent frames 100, a buffer device 130 is provided on the end bearing plate 122, a coupler and a buffer are installed in the buffer device 130, and the adjacent frames 100 are connected to each other by the coupler and are damped by the buffer.

As shown in fig. 1 to 5, in particular, mounting frames 140 are further connected to tops of two ends of the frame 100 in the length direction, that is, the mounting frames 140 are connected to the corner posts 114 through two channel steels to form a triangular structure, an edge-sealed channel steel is further connected between the channel steels on the two corner posts 114 to form the mounting frames 140, and a current collector 600 is mounted on the mounting frames 140 and is used for receiving electric energy. Meanwhile, the upper surface of the end support 120 is further connected with a mounting seat 150 formed by two channel steels, an electrical cabinet 400 is mounted on the mounting seat 150 at one end of the frame 100 and used for controlling electric energy, and a super capacitor 500 or a storage battery is mounted on the mounting seat 150 at the other end of the frame 100 and used for storing electric energy.

According to the invention, the current collectors 600 are arranged at the top positions of the two ends of the vehicle through the mounting frames 140, and the station charging device is correspondingly arranged above the vehicle, so that a larger space can be reserved for goods transportation on the ground, and the efficiency of underground pipeline transportation is further improved. Meanwhile, the super capacitor 500 or the storage battery is mounted on the mounting seat 150, when the vehicle loads and unloads goods at a station, the vehicle is charged, and a power transmission line does not need to be arranged in the pipeline or the arrangement of the power transmission line is reduced, so that the construction cost of the pipeline is greatly reduced.

As shown in fig. 6 to 9, the bogie 200 includes a plate frame 210 and a guide frame 231. The plate frame 210 is a box-type structure with an i-shape as a whole to meet the load-bearing requirements of the frame 100. The plate frame 210 includes an upper cover plate 211, a lower cover plate 212, and a sealing plate 213, where the upper cover plate 211 and the lower cover plate 212 are both i-shaped and are disposed opposite to each other. The edge sealing plates 213 are connected between the upper cover plate 211 and the lower cover plate 212 along the plate edges between the upper cover plate 211 and the lower cover plate 212, so that the upper cover plate 211, the lower cover plate 212 and the edge sealing plates 213 are enclosed to form an i-shaped box structure. The upper cover plate 211, the lower cover plate 212 and the edge sealing plate 213 are connected by welding or bolting.

As shown in fig. 8, two ends of the two edge sealing plates 213 located in the middle of the i-shape extend to the two edge sealing plates 213 located in the edge of the i-shape, so that the i-shaped plate frame 210 forms a box-type structure with four limbs as independent closed spaces. Meanwhile, the middle part of the plate frame 210 also forms a box structure of a long strip-shaped independent closed space.

As shown in fig. 6 to 9, a semicircular connecting plate 214 is connected to the i-shaped opening of the upper cover plate 211 by welding or bolting, and similarly, a semicircular connecting plate 214 is connected to the i-shaped opening of the lower cover plate 212. The connecting plate 214 on the upper cover plate 211 and the connecting plate 214 on the lower cover plate 212 enclose to form an annular structure, the annular structure is used as a running part of the plate type framework 210, a flange plate 215 is connected to the annular surface of the annular structure in a welding or bolt connection mode, and a plurality of threaded holes are formed in the flange plate 215 and used for mounting the running wheels 220. Further, a reinforcing ring 216 is attached to the inner peripheral side of the annular structure by welding or bolting for enhancing the attachment strength of the connection plate 214. Of course, in order to increase the overall strength of the connecting plates 214, two connecting plates 214 may be respectively connected to the upper cover plate 211 and the lower cover plate 212 at the same side of the i-shaped opening, and the reinforcing ring 216 is connected between the two connecting plates 214.

As shown in fig. 8, in order to further enhance the load-bearing capacity of the panel frame 210, first and second reinforcing

bulkheads

2131 and 2132 are provided in the limb-independent closed spaces of the panel frame 210, respectively. The first reinforcing partition 2131 is parallel to the edge sealing plate 213 at the edge of the i-shape, and the second reinforcing partition 2132 is parallel to the edge sealing plate 213 at the middle of the i-shape. Thus, the blank plate 213, the first reinforcing spacer 2131 and the second reinforcing spacer 2132 are supported between the upper cover plate 211 and the lower cover plate 212, and share the weight of the vehicle frame 100. Of course, depending on the specific size of the panel frame 210 and the specific size of the individual enclosures of each limb, it is also possible to provide more reinforcing partitions, such as reinforcing partitions arranged in a zig-zag pattern, within each individual enclosure of a limb. In addition, according to the stress condition of the plate frame 210, an angle between the reinforcing partition and the edge sealing plate 213 can be formed, for example, the reinforcing partition in the shape of a slant-well.

As shown in fig. 6 to 9, the guide frames 231 are coupled to four corners of the lower cover plate 212 by welding or bolting. The guide frame 231 is provided with bolt holes for connecting the guide wheels 230, and three reinforcing ribs 2311 are connected between the guide frame 231 and the lower cover plate 212 by welding or bolting for enhancing the structural strength of the guide frame 231. The plate surface of the guide frame 231 is parallel to the traveling direction of the guide wheel 230, and the three ribs 2311 are perpendicular to the plate surface of the guide frame 231.

The plate type framework 210 designed by the invention is connected with the running wheels 220 through the flange plates 215 on the running part and is also connected with the guide wheels 230 through the guide frames 231, so that the guide wheels 230 play a role of guiding the plate type framework 210 on the guide surfaces 292 while the running wheels 220 run on the running surface 291. The shape of the drainage ditch arranged in the pipeline is fully utilized, and the design of the guide rail in the pipeline is cancelled. In addition, the plate type framework 210 is integrally in an I-shaped box structure, and the reasonable structural design of the edge sealing plate 213, the first reinforcing partition plate 2131 and the second reinforcing partition plate 2132 can greatly reduce the overall dimension of the bogie 200 on the premise of bearing the same gravity of the frame 100, thereby being beneficial to shortening the length of an underground pipeline transport vehicle and improving the flexibility of pipeline lines. The annular structure design of the walking part can also facilitate the installation of the first driving motor 240 for driving the walking wheels 220 to walk, so that the first driving motor 240 is positioned inside the plate-type framework 210.

It will be appreciated that if the bogie 200 is designed to have two, three or more axles according to the load-bearing requirements of the plate frames 210, a plurality of the plate frames 210 may be connected to each other in the traveling direction of the traveling wheels 220 to form the two, three or more axles of the bogie 200. Of course, the plate frame 210 of the present invention may also be designed as a rectangular box structure, and the running part is integrally designed above the plate frame 210, so that the running wheels 220 can run on the running surface 291, and the guide wheels 230 can run on the guide surfaces 292, and meanwhile, the plate frame 210 of the rectangular box structure has a smaller size and shape than the frame of the side frame or the beam type bogie.

As shown in fig. 6 to 9, spring assembly holes 2111 are formed at four corners of the upper plate 211 for mounting the spring assemblies 250. The third reinforcing partition 2133 is also arranged in the independent closed space corresponding to the spring assembly hole 2111, the first reinforcing partition 2131 and the third reinforcing partition 2133 sink towards the lower cover plate 212 at the position of the spring assembly hole 2111, namely, the first reinforcing partition 2131 and the third reinforcing partition 2133 are provided with notches at the position of the spring assembly hole 2111, so that the height of the spring assembly 250 can be increased, and the vehicle has better dynamic performance. Of course, when the cross-sectional size of the spring assembly aperture 2111 is designed to be larger, more third reinforcing baffles 2133 may be designed, or the second reinforcing baffles 2132 may be used directly as the third reinforcing baffles 2133. At this time, the sinking heights of the first, second, and third reinforcing

baffles

2131, 2132, and 2133 are the same.

As shown in fig. 6 to 9, pin bushing holes 2112 are formed at the center positions of the upper cover plate 211 and the lower cover plate 212, respectively, and a pin bushing 217 for mounting the kingpin 270 is connected between the pin bushing hole 2112 of the upper cover plate 211 and the pin bushing hole 2112 of the lower cover plate 212 by welding or bolting. The pin bush 217 is further connected with the edge sealing plates 213, in order to enhance the connection strength of the pin bush 217, a fourth reinforcing partition 2134 is connected between the two edge sealing plates 213 positioned in the middle of the i shape in a welding or bolt connection mode, and the fourth reinforcing partition 2134 is welded with the pin bush 217. Further, a second damper base 218 is connected to the edge sealing plate 213 at the edge of the panel frame 210, and is used to mount a damper 280 connected between the vehicle body frame 100 and the panel frame 210. Wherein, the second vibration damping bases 218 are symmetrically arranged at both sides of the plate type frame 210.

As shown in fig. 9 and 10, the running wheels 220 are connected to the flange plates 215 at both sides of the plate frame 210 by bolts, and when the bogie 200 is designed as a power bogie, the first driving motor 240 for driving the running wheels 220 to run can be installed in an annular structure, so that the first driving motor 240 is positioned at the opening position of the i-shaped plate frame 210, thereby preventing the first driving motor 240 from protruding out of the plate frame 210 and protecting the first driving motor 240. The guide wheels 230 are mounted on guide frames 231 provided at four corners of the lower cover plate 212 by bolts. When the plate frame 210 travels on the drain, the running wheels 220 run along the running surface 291 of the drain, and the guide wheels 230 run along the guide surface 292 of the drain.

As shown in fig. 6-9, a spring assembly 250 is mounted within the spring assembly bore 2111, the spring assembly 250 being connected to the spring seat 123 on the end bracket 120 and within the spring assembly bore 2111. Because the spring assembly holes 2111 are of a sunken structural design, the spring assemblies 250 can be designed to a higher height, resulting in better vehicle dynamics. A towing ball joint 260 is installed in the pin bushing hole 2112, a towing pin 270 is connected to the towing ball joint 260, and the frame 100 is connected to the panel frame 210 through the towing pin 270. The damper 80 is installed between the first damper seat 124 and the second damper seat 218.

As shown in fig. 10, the plate type bogie of the present invention has a compact structural design, and through the box type structural design and the arrangement of the reinforcing partition plate in the plate type frame 210, the overall dimension of the bogie can be reduced on the premise of meeting the bearing requirement of the bogie, so that the length of the vehicle is shortened, and the flexibility of pipeline layout is facilitated. According to the invention, the running wheels 220 are designed on the running surface 291 of the drainage ditch to run and the guide wheels 230 are designed on the guide surface 292 of the drainage ditch to run according to the structural characteristics of the drainage ditch, so that the design of guide rails can be omitted for pipelines, and the construction cost of the pipelines is saved.

In particular, the running wheels 220 and the guide wheels 230 of the present invention both adopt rubber wheel structures, which can reduce the impact force of the vehicle on the running surface 291 and the guide surface 292, thereby prolonging the service life of the pipeline.

As shown in fig. 11 to 13, the conveying and clamping device 300 includes a bracket, a roller 320, and a clamping assembly. The support includes two supporting beam 310 that set up relatively, and the support can select for use materials such as channel-section steel, I-steel or square tube to make and form, and two supporting beam 310 set up relatively on the bottom plate 113 of frame 100 through welding or bolted connection's mode, and two supporting beam 310 all are perpendicular to the direction of travel of frame 100. The rollers 320 are rotatably connected between the two support beams 310, for example, holes may be formed in the two support beams 310 or bearings may be provided on the two support beams 310, so that the rollers 320 can rotate on the supports after being connected to the support beams 310. The length direction of each roller 320 is the same as the traveling direction of the vehicle frame 100 so as to load and unload goods from both sides of the vehicle. Wherein, the upper surfaces of the plurality of rollers 320 are lower than the upper surfaces of the support beams 310 at two sides, so that the goods loaded on the vehicle can define the placing position of the goods along the driving direction of the vehicle frame 100 through the height difference between the rollers 320 and the support beams 310.

As shown in fig. 11, a second driving motor 380 is mounted on the supporting beam 310 on one side, and a transmission port 312 is formed on the upper surface of the supporting beam 310 at a position corresponding to the output end of the second driving motor 380. A transmission member 370 is disposed in the support beam 310, and the transmission member 370 may be a chain engaged with the output end of the second driving motor 380 through the transmission opening 312. As shown in FIG. 12, the rollers 320 are provided with gears 390 located in the support beam 310 at one side of the second driving motor 380, and the gears 390 of the plurality of rollers 320 are all connected with the chain in a meshed manner. When the second driving motor 380 operates, the chain drives the plurality of rollers 320 to rotate simultaneously along with the rotation of the second driving motor 380, so that the function that the plurality of rollers 320 drive the goods to move in the frame 100 is realized. Of course, the driving member 370 may also be a driving belt, so that the plurality of rollers 320 are driven by the driving belt to rotate on the supporting beam 310.

Specifically, proximity switches 11 are further mounted on the support beam 310 on the side of the second driving motor 380, and the two proximity switches 11 are respectively located at both ends of the support beam 310. When the two proximity switches 11 detect the goods, the second driving motor 380 stops running, so that the roller 320 stops acting; when any one of the two proximity switches 11 detects the goods, the second driving motor 380 keeps operating, rotating the drum 320. According to the invention, the two proximity switches 11 are arranged on the supporting beam 310, so that the roller 320 can be automatically started and stopped according to the loading and unloading states of goods, the automatic operation of goods conveying is realized, and the manual labor intensity is reduced.

As shown in fig. 11, in order to ensure the stability of the goods during transportation, the present invention further provides a clamping assembly on the support beam 310 for clamping the goods on the roller 320. Specifically, the clamping assembly includes a clamping arm 330, two columns 340 are respectively connected to two ends of the supporting beam 310 opposite to the second driving motor 380 by welding or bolting, and the tops of the columns 340 are hinged to the clamping arm 330.

As shown in FIG. 11, the clamping arm 330 is an L-shaped structure, the upright 340 is hinged to the corner of the L-shaped structure, and a telescopic device 350 is hinged between the short sides of the two L-shaped structures. When the telescoping device 350 is extended, the long side of the L-shaped structure approaches the support beam 310 to avoid the clamp arm 330 blocking the loading and unloading of the cargo; when the telescopic device 350 is shortened, the long side of the L-shaped structure is far away from the support beam 310, and the goods are tightly pressed on the roller 320 through the long side of the L-shaped structure of the clamping arm 330, so that the stability of the goods in the transportation process is ensured.

In particular, two stops 360 are connected to the support beam 310 by welding or bolting, and the two stops 360 correspond to positions of the long sides of the L-shaped structure when the long sides of the L-shaped structure are close to the support beam 310. When clamp arm 330 is brought closer to support beam 310 by telescoping device 350, stop 360 limits the return of the long side of the L-shaped structure to the position of support beam 310. The telescopic device 350 may be a cylinder, a hydraulic cylinder, or an electric pushing cylinder.

In the loading process of the goods, when the goods are transported to the door of the vehicle, the second driving motor 380 is started, and the goods are transferred into the vehicle frame 100 through the rotation of the rollers 320. When the placing position of the goods in the frame 100 needs to be adjusted, the placing position can be adjusted by controlling the rotation of the second driving motor 380. During unloading, the cargo is moved to the door of the vehicle by controlling the second driving motor 380, and then is transferred to a designated position. In the whole cargo carrying process, manual participation is not needed, the function of moving the cargo in the frame 100 is realized, and the labor intensity of workers is reduced.

It is understood that the clamping assembly, the pillar 340 and the stopper 360 of the present invention can be disposed not only on the support beam 310, but also on the frame 100 by welding or bolting, and can also clamp the goods on the roller 320. Of course, the clamping assembly can also be designed into a structural form that goods are directly pushed through a telescopic device such as an air cylinder, a hydraulic cylinder or an electric pushing cylinder. However, the clamping assembly is designed to be the structural form of the clamping arm 330, so that the space of the vehicle can be saved, and the loading rate of goods transportation is improved.

As shown in fig. 11 and 13, two sets of conveying clamping devices of the present invention are disposed on the bottom plate 113 of the vehicle frame 100 according to the actual length of the vehicle frame 100, so that the span of the roller 320 can be reduced, and the load-bearing capacity of the roller 320 for the goods can be increased. Specifically, the support beams 310 on the side where the second driving motors 380 are installed on the two sets of conveying clamping devices are adjacently arranged, the support beams 310 on the side of the clamping arms 330 are far away from each other, and when the two sets of second driving motors 380 are positively rotated, the rotating directions of the rollers 320 on the two sets of conveying clamping devices are opposite. That is, the two sets of conveying jigs are centrosymmetric with respect to the midpoint of the support beam 310 on the side where the second driving motor 380 is installed.

In the process of loading and unloading goods, the two groups of conveying clamping devices which are arranged in central symmetry can enable goods to be loaded and unloaded from two sides of a vehicle simultaneously, and therefore the efficiency of loading and unloading goods is improved. Of course, depending on the actual length of the vehicle frame 100, a greater number of sets of conveying and clamping devices may be provided within the vehicle frame 100 in the direction of travel of the vehicle frame 100, thereby achieving automation of the loading and unloading of the entire vehicle.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
