Description

Technical Field

[0001] The present invention belongs to the technical field of logistics support, and specifically relates to a logistics supply device for rail transit construction. Background Art

[0002] Logistics supply devices are generally required at the construction sites of rail transit, such as drinking water supply and food supply, etc., to maintain the logistics support work of construction workers and enable them to maintain a high-efficiency working state.

[0003] A Chinese patent with the publication number CN104002723A discloses a logistics support vehicle, which includes a chassis vehicle, a carriage, a generator, a stove, a fuel tank, a water tank. Inside the carriage, there are food and gas safety detection devices and sterilization lamps, and devices such as lighting lamps, escape windows, smoke exhaust devices, water heaters, sinks, wall cabinets, power distribution cabinets, intelligent fire extinguishing systems, on-vehicle refrigerators, double-door disinfection cabinets, water pumps, water purifiers, etc. are installed. In order to improve its support efficiency, shorten the time, reduce the labor intensity of operators, and at the same time, it is particularly important to provide a safe, reliable, convenient-to-operate logistics support vehicle that ensures personal safety. Such a logistics support vehicle can conduct safety detection on food raw materials and harmful gases, be used for sterilizing the vehicle interior environment, and can also check whether the gases for preservation and sterilization and combustible gases exceed the standard, ensuring the safe consumption of food and preventing invisible harm to operators from toxic and harmful gases during the operation process.

[0004] The logistics supply devices in the prior art can only provide general drinking water supply or food supply. Especially during the high-temperature period in summer, the drinking water provided by the logistics supply devices has a relatively high temperature, which cannot relieve the heat of construction workers in time and is likely to cause problems such as the low spirits of construction workers or even heatstroke.

[0005] Therefore, the present invention provides a logistics supply device for rail transit construction. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A logistics supply device for rail transit construction described in the present invention includes a base; a box body and a refrigeration component are fixedly connected to the upper side of the base; a refrigerated compartment and a freezer compartment are provided inside the box body, and both the refrigerated compartment and the freezer compartment are cooled by the refrigeration component; a group of placement openings are provided on one side of the refrigerated compartment; a group of placement cylinders are fixedly connected to the position inside the refrigerated compartment close to the placement openings, and the placement cylinders are in an inclined state; water cups are provided inside the placement cylinders, and the tops of the water cups extend outside the box body through the placement openings; The logistics supply devices in the prior art can only provide general drinking water supply or food supply. Especially during the high-temperature period in summer, the drinking water provided by the logistics supply devices is at a relatively high temperature, which cannot relieve heat for the construction workers in time and is likely to cause problems such as the construction workers being in a low state or even suffering from heat stroke; At this time, the logistics supply device in the present invention is provided with a refrigerated compartment and a freezer compartment. The temperature of the refrigerated compartment is higher than that of the freezer compartment. The water cups can be stored in the placement cylinders inside the refrigerated compartment to provide ice drinking water for the construction workers. And it is convenient to take and store the water cups through the placement openings. Some frozen foods such as ice cream bars and ice cream can be stored in the freezer compartment for the construction workers to eat. Through this device, better logistics services can be provided, enabling the construction workers to maintain a high-efficiency working state.

[0008] Preferably, a group of rotating shafts are rotatably connected inside the base; both ends of the rotating shafts extend outside the base and are installed with rollers; the freezer compartment includes a plurality of freezing cells; a side groove is provided on one side of the freezing cell, and a movable door is installed inside the side groove through a hinge; By providing the rollers, it is convenient to pull this device at the construction site, improving the service scope of logistics supply. And by providing a plurality of freezing cells, it is convenient for storing and taking frozen foods, and at the same time, it is also convenient for classifying frozen foods.

[0009] Preferably, a connecting shaft is rotatably connected inside the freezer compartment, and the connecting shaft is driven by a power component; the connecting shaft penetrates through a plurality of freezing cells; a scraping rod is fixedly connected to the position of the connecting shaft close to the bottom of the freezing cell, and the scraping rod is in contact with the bottom of the freezing cell; a sheath is fixedly connected inside the freezing cell, and the connecting shaft is located inside the sheath and is rotatably connected thereto; a grid plate is fixedly connected to the bottom of the freezing cell, and the grid plate is located above the scraping rod; After long-term use, a layer of frost will inevitably form on the bottom of the freezing cell. Over time, the refrigeration efficiency of the freezer compartment will be reduced, and the storage space of the freezing cell will be reduced. At this time, the power component drives the connecting shaft and a plurality of scraping rods to rotate. Then the scraping rod rotates and scrapes on the bottom of the freezing cell, thereby scraping off the frost on the bottom of the freezing cell, reducing frost residue. And by providing a grid plate at the bottom of the freezing cell, frozen foods can be stored on the surface of the grid plate to prevent the rotation of the scraping rod from affecting the frozen foods.

[0010] Preferably, the power assembly includes a bevel gear ring fixedly connected to the outside of the rotating shaft; a bevel gear is fixedly connected to the bottom of the connecting shaft, and the bevel gear meshes with the bevel gear ring; when pulling the equipment to transfer its position, the rotation of the roller will drive the bevel gear ring to rotate through the rotating shaft, the bevel gear ring drives the bevel gear to rotate, and then the bevel gear synchronously drives the connecting shaft to rotate. By using the roller as the power source to provide power for the connecting shaft, the rotation of the roller is effectively utilized, eliminating the need to install additional driving devices such as motors, thereby improving the energy-saving effect of the equipment.

[0011] Preferably, a group of mounting strips are evenly distributed on the upper side of the scraping rod; a group of bristles are fixedly connected to the top of the mounting strips; by providing the mounting strips and the bristles, the bristles will extend into the holes of the grid plate during the rotation of the scraping rod for frictional scraping, thereby preventing excessive ice and frost from being generated inside the grid plate.

[0012] Preferably, the placing cylinder is made of a grid material, and the diameter of the mesh holes at the top of the placing cylinder is larger than that at the bottom; the number of placing cylinders is the same as and corresponds one-to-one with the number of freezing cells, and a slag guiding channel is communicated between the bottom of the mutually adjacent freezing cells and the top of the placing cylinder, and the slag guiding channel is in an inclined state; by setting the placing cylinder as a grid material, the cold air can directly contact the water cup through the placing cylinder, improving the cooling efficiency of the cold air on the water cup. At the same time, the ice slag scraped from the bottom of the freezing cell will be deflected by the scraping rod and fall into the slag guiding channel, and then enter the placing cylinder along the slag guiding channel. Since the mesh holes at the bottom of the placing cylinder are smaller, the ice slag will remain at the bottom of the placing cylinder and contact the water cup, further improving the ice-cooling effect on the water cup, thereby effectively utilizing the scraped ice slag. Since the mesh holes at the top of the placing cylinder are larger, when there is more ice slag in the placing cylinder, it will overflow through the mesh holes at the top and fall to the bottom of the refrigerator compartment.

[0013] Preferably, the scraping rod is made of iron, and the slag guiding channel is made of an elastic material; an elastic sheet is fixedly connected between the upper side of the slag guiding channel and the side wall of the refrigerator compartment; a magnetic block is fixedly connected to the middle of the elastic sheet, and the magnetic block can attract each other when approaching the scraping rod; when the scraping rod rotates to a position close to the slag guiding channel, due to the material of the scraping rod being iron, an attractive force will be generated between the scraping rod and the magnetic block, and then the magnetic block drives the elastic sheet to deform. When the scraping rod rotates to a position away from the slag guiding channel, the elastic sheet automatically resets. In this way, the elastic sheet continuously drives the slag guiding channel to vibrate, promoting the smooth falling of the ice slag inside the slag guiding channel and avoiding the problem of the slag guiding channel being blocked by ice slag.

[0014] Preferably, a slag discharge hole is provided inside the base, and the slag discharge hole connects the cold storage chamber with the outside; a pair of flexible diaphragms are fixedly connected to the inside of the slag discharge hole; the free ends of the flexible diaphragms are squeezed against each other and fixedly connected to a pair of magnetic sheets, and the pair of magnetic sheets are attracted to each other; the ice debris overflowing from the placement tube and the moisture formed after the ice debris melts will be discharged outward through the slag discharge hole, and by arranging the flexible diaphragm and the magnetic sheet, the pair of magnetic sheets are attracted to each other, so that the pair of flexible diaphragms block the slag discharge hole, avoiding the problem of excessive dust on the construction site and entering the cold storage chamber through the slag discharge hole; when there is enough ice debris on the upper side of the flexible diaphragm, the flexible diaphragm cannot withstand the large gravity, prompting the pair of magnetic sheets to separate, and at this time the ice debris and moisture can be discharged smoothly through the slag discharge hole, and then the pair of flexible diaphragms are re-closed under the action of their own elastic force and block the slag discharge hole.

[0015] Preferably, a sealing air ring is fixedly connected to the inside of the placement port; an air storage bag is fixedly connected to the bottom of the placement tube, and the air storage bag is connected to the sealing air ring through a pipeline; when the water cup is placed inside the placement tube, the water cup will squeeze the air storage bag at the bottom, and then the gas inside the air storage bag will be filled into the sealing air ring through the pipeline, causing the sealing air ring to expand and fit tightly with the surface of the water cup, thereby improving the sealing degree of the placement port, reducing the external dust from entering the interior of the refrigerator through the placement port, and also reducing the overflow of cold air through the placement port.

[0016] Preferably, a water-absorbing film is fixed to the inner side of the sealing air ring, and the material of the water-absorbing film is sponge; by providing the water-absorbing film, when the water cup is taken out, the water-absorbing film can wipe off the ice debris and water on the surface of the water cup, avoiding the problem of slipping when the staff takes it.

[0017] The beneficial effects of the present invention are as follows:

The placement opening makes it convenient to take and store water cups. Some frozen foods, such as popsicles and ice cream, can be stored in the freezer chamber for construction workers to eat. This equipment can provide better quality logistics services, allowing construction workers to maintain a high-efficiency working state.

Specific Embodiments

[0028] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0029] Embodiment 1

[0030] As Figures 1 to 5As shown in the figure, a logistics supply device for rail transit construction according to an embodiment of the present invention includes a base 1; a box body 2 and a refrigeration component 3 are fixedly connected to the upper side of the base 1; a refrigerated chamber 4 and a freezer 5 are arranged inside the box body 2, and both the refrigerated chamber 4 and the freezer 5 are cooled by the refrigeration component 3; a group of placement openings 6 are formed on one side of the refrigerated chamber 4; a group of placement cylinders 7 are fixedly connected inside the refrigerated chamber 4 near the placement openings 6, and the placement cylinders 7 are in an inclined state; water cups 8 are arranged inside the placement cylinders 7, and the tops of the water cups 8 extend outside the box body 2 through the placement openings 6; the logistics supply devices in the prior art can only provide general drinking water supply or food supply. Especially during the high-temperature period in summer, the drinking water provided by the logistics supply device is at a relatively high temperature, which cannot relieve the heat of the construction workers in time and is likely to cause problems such as the construction workers being in a low state or even suffering from heatstroke. At this time, the logistics supply device in the present invention is provided with a refrigerated chamber 4 and a freezer 5. The temperature of the refrigerated chamber 4 is higher than that of the freezer 5. The water cups 8 can be stored in the placement cylinders 7 inside the refrigerated chamber 4 to provide ice drinking water for the construction workers. Moreover, it is convenient to take and store the water cups 8 through the placement openings 6. Some frozen foods, such as ice lollies and ice creams, can be stored inside the freezer 5 for the construction workers to eat. Through this device, higher-quality logistics services can be provided, enabling the construction workers to maintain a high-efficiency working state.

[0031] A group of rotating shafts 9 are rotatably connected inside the base 1; both ends of the rotating shafts 9 extend outside the base 1 and rollers 10 are installed; the freezer 5 includes a plurality of freezing cells 11; a side groove is formed on one side of the freezing cell 11, and a movable door 12 is installed inside the side groove through a hinge; by providing the rollers 10, it is convenient to pull this device at the construction site, improving the service range of logistics supply. Moreover, by providing a plurality of freezing cells 11, it is convenient to store, take and classify frozen foods.

[0032] A connecting shaft 13 is rotatably connected inside the freezer compartment 5, and the connecting shaft 13 is driven by a power assembly; the connecting shaft 13 penetrates through a plurality of freezing cells 11; a scraping rod 14 is fixedly connected to a position of the connecting shaft 13 close to the bottom of the freezing cell 11, and the scraping rod 14 is in contact with the bottom of the freezing cell 11; a sheath 15 is fixedly connected inside the freezing cell 11, and the connecting shaft 13 is located inside the sheath 15 and is rotatably connected thereto; a grid plate 18 is fixedly connected to the bottom of the freezing cell 11, and the grid plate 18 is located above the scraping rod 14. After long-term use, an inevitable layer of ice frost will be generated at the bottom of the freezing cell 11. Over time, the refrigeration efficiency of the freezer compartment 5 will be reduced, and the storage space of the freezing cell 11 will be reduced. At this time, the power assembly drives the connecting shaft 13 and a plurality of scraping rods 14 to rotate. Then, the scraping rod 14 rotates and scrapes at the bottom of the freezing cell 11, so as to scrape off the ice frost at the bottom of the freezing cell 11, reduce the ice frost residue, and by arranging the grid plate 18 at the bottom of the freezing cell 11, frozen foods can be stored on the surface of the grid plate 18 to prevent the rotation of the scraping rod 14 from affecting the frozen foods.

[0033] The power assembly includes a bevel gear ring 16, and the bevel gear ring 16 is fixedly connected to the outside of the rotating shaft 9; a bevel gear 17 is fixedly connected to the bottom of the connecting shaft 13, and the bevel gear 17 meshes with the bevel gear ring 16; when pulling the device to move its position, the rotation of the roller will drive the bevel gear ring 16 to rotate through the rotating shaft 9, the bevel gear ring 16 drives the bevel gear 17 to rotate, and then the bevel gear 17 synchronously drives the connecting shaft 13 to rotate. By using the roller as a power source to provide power for the connecting shaft 13, the rotation of the roller is effectively utilized, and there is no need to additionally install a driving device such as a motor, which improves the energy-saving effect of the device.

[0034] A group of mounting strips 19 are evenly distributed on the upper side of the scraping rod 14; a group of bristles 20 are fixedly connected to the top of the mounting strips 19; by arranging the mounting strips 19 and the bristles 20, the bristles 20 will extend into the holes of the grid plate 18 for frictional scraping during the rotation of the scraping rod 14, so as to avoid the generation of more ice frost inside the grid plate 18.

[0035] The placing tube 7 is made of a mesh material, and the mesh diameter at the top of the placing tube 7 is larger than the mesh diameter at the bottom; the placing tube 7 is the same in number as the freezing cells 11 and corresponds one to one, and the bottoms of the freezing cells 11 adjacent to each other are connected to the top of the placing tube 7 through a slag guide 21, and the slag guide 21 is in an inclined state; by setting the placing tube 7 as a mesh material, the cold air can directly contact the water cup 8 through the placing tube 7, thereby improving the cooling efficiency of the cold air on the water cup 8. At the same time, the ice debris scraped off from the bottom of the freezing cell 11 will be moved by the scraper 14 and fall into the slag guide 21 and enter the placing tube 7 along the slag guide 21. Since the mesh holes at the bottom of the placing tube 7 are small, the ice debris will remain at the bottom of the placing tube 7 and contact the water cup 8, further improving the cooling effect of the water cup 8, thereby effectively utilizing the scraped ice debris. Since the mesh holes at the top of the placing tube 7 are large, when there is a lot of ice debris in the placing tube 7, it will overflow through the mesh holes at the top and fall to the bottom of the refrigerating chamber 4.

[0036] The scraper 14 is made of iron, and the slag guide channel 21 is made of elastic material; an elastic sheet 22 is fixed between the upper side of the slag guide channel 21 and the side wall of the cold storage chamber 4; a magnetic block 23 is fixed to the middle of the elastic sheet 22, and the magnetic block 23 and the scraper 14 can attract each other when they are close to each other; when the scraper 14 rotates to a position close to the slag guide channel 21, since the scraper 14 is made of iron, an attraction will be generated between the scraper 14 and the magnetic block 23, and then the magnetic block 23 drives the elastic sheet 22 to deform, and when the scraper 14 rotates to a position away from the slag guide channel 21, the elastic sheet 22 automatically resets. Such a cycle makes the elastic sheet 22 continuously drive the slag guide channel 21 to shake, promote the ice slag inside the slag guide channel 21 to fall smoothly, and avoid the problem of ice slag blocking the slag guide channel 21.

[0037] The base 1 is provided with a slag discharge hole 24, and the slag discharge hole 24 connects the cold storage chamber 4 with the outside; a pair of flexible diaphragms 25 are fixedly connected to the slag discharge hole 24; the free ends of the flexible diaphragms 25 are squeezed against each other and fixedly connected to a pair of magnetic sheets 26, and the pair of magnetic sheets 26 are attracted to each other; the ice debris overflowed from the placement tube 7 and the water formed after the ice debris melts will be discharged outward through the slag discharge hole 24. By providing the flexible diaphragm 25 and the magnetic sheet 26, the pair of magnetic sheets 26 are attracted to each other, so that the pair of flexible diaphragms 25 block the slag discharge hole 24, thereby avoiding the problem of excessive dust on the construction site and entering the cold storage chamber 4 through the slag discharge hole 24. When there is enough ice debris on the upper side of the flexible diaphragm 25, the flexible diaphragm 25 cannot withstand the large gravity, prompting the pair of magnetic sheets 26 to separate. At this time, the ice debris and water can be discharged smoothly through the slag discharge hole 24, and then the pair of flexible diaphragms 25 are re-closed under the action of their own elastic force and block the slag discharge hole 24.

[0038] A sealing air ring 27 is fixedly connected inside the placement opening 6; a storage air bag 28 is fixedly connected to the bottom of the placement cylinder 7, and the storage air bag 28 is communicated with the sealing air ring 27 through a pipeline; when the water cup 8 is stored inside the placement cylinder 7, the water cup 8 will squeeze the storage air bag 28 at the bottom, and then the gas inside the storage air bag 28 is filled into the sealing air ring 27 through the pipeline, prompting the sealing air ring 27 to expand and closely fit the surface of the water cup 8, improving the sealing degree of the placement opening 6, reducing the entry of external dust into the refrigerating chamber 4 through the placement opening 6, and at the same time reducing the overflow of cold air through the placement opening 6.

[0039] Embodiment 2

[0040] As Figure 6 shown, compared with Embodiment 1, another implementation manner of the present invention is: a water absorption film 29 is fixedly connected to the inner side of the sealing air ring 27, and the material of the water absorption film 29 is sponge; by providing the water absorption film 29, when taking out the water cup 8, the water absorption film 29 can wipe off the ice slag and moisture on the surface of the water cup 8, avoiding the problem of slipping when the staff takes it.

[0041] Working principle: The logistics supply equipment in the present invention is provided with a refrigerating chamber 4 and a freezing chamber 5. The temperature of the refrigerating chamber 4 is higher than that of the freezing chamber 5. The water cup 8 can be stored in the placing cylinder 7 inside the refrigerating chamber 4 to provide ice-cold drinking water for the construction workers. And through the placing opening 6, it is convenient to take and store the water cup 8. Some frozen foods such as ice lollies and ice creams can be stored inside the freezing chamber 5 for the construction workers to eat. Through this equipment, better logistics services can be provided, enabling the construction workers to maintain a high-efficiency working state; by setting the rollers 10, it is convenient to pull this equipment at the construction site, expanding the service scope of logistics supply. And by setting a plurality of freezing cells 11, it is convenient for the storage, taking and classification of frozen foods; after long-term use, an inevitable layer of frost will be generated at the bottom of the freezing cell 11. Over time, the refrigeration efficiency of the freezing chamber 5 will be reduced, and the storage space of the freezing cell 11 will be reduced. At this time, the power assembly drives the connecting shaft 13 and a plurality of scraping rods 14 to rotate. Then the scraping rods 14 rotate and scrape at the bottom of the freezing cell 11, thereby scraping off the frost at the bottom of the freezing cell 11, reducing the frost residue. And by setting a grid plate 18 at the bottom of the freezing cell 11, the frozen foods can be stored on the surface of the grid plate 18 to prevent the rotation of the scraping rods 14 from affecting the frozen foods; when pulling this equipment to transfer its position, the rotation of the rollers will drive the bevel gear ring 16 to rotate through the rotating shaft 9. The bevel gear ring 16 drives the bevel gear 17 to rotate. Then the bevel gear 17 synchronously drives the connecting shaft 13 to rotate. By using the rollers as the power source to provide power for the connecting shaft 13, the rotation of the rollers is effectively utilized, eliminating the need to install additional driving devices such as motors, improving the energy-saving effect of this equipment; by setting the mounting strip 19 and the bristles 20, during the rotation of the scraping rods 14, the bristles 20 will extend into the holes of the grid plate 18 for frictional scraping, thus preventing more frost from being generated inside the grid plate 18; by setting the placing cylinder 7 as a grid material, the cold air can pass through the placing cylinder 7 and directly contact the water cup 8, improving the cooling efficiency of the cold air on the water cup 8. At the same time, the ice slag scraped from the bottom of the freezing cell 11 will be deflected by the scraping rods 14 and fall into the slag guide 21, and then enter the placing cylinder 7 along the slag guide 21. Since the mesh holes at the bottom of the placing cylinder 7 are relatively small, the ice slag will be retained at the bottom of the placing cylinder 7 and contact the water cup 8, further improving the ice-cooling effect on the water cup 8, thereby effectively utilizing the scraped ice slag. Since the mesh holes at the top of the placing cylinder 7 are relatively large, when there is more ice slag in the placing cylinder 7, it will overflow through the top mesh holes and fall to the bottom of the refrigerating chamber 4; when the scraping rods 14 rotate to a position close to the slag guide 21, due to the material of the scraping rods 14 being iron, an attractive force will be generated between the scraping rods 14 and the magnetic blocks 23. Then the magnetic blocks 23 drive the elastic pieces 22 to deform. And when the scraping rods 14 rotate to a position far from the slag guide 21, the elastic pieces 22 automatically reset. Such a cycle makes the elastic pieces 22 continuously drive the slag guide 21 to vibrate, promoting the smooth falling of the ice slag inside the slag guide 21 and avoiding the problem of the slag guide 21 being blocked by the ice slag;The ice slag overflowing from the placement cylinder 7 and the moisture formed after the ice slag melts will be discharged outward through the slag discharge hole 24. By setting the flexible diaphragm 25 and the magnetic sheet 26, since a pair of magnetic sheets 26 attract each other, a pair of flexible diaphragms 25 block the slag discharge hole 24, avoiding the problem that the dust at the construction site is relatively large and enters the refrigerating chamber 4 through the slag discharge hole 24. When there is enough ice slag on the upper side of the flexible diaphragm 25, the flexible diaphragm 25 cannot bear the greater gravity, prompting a pair of magnetic sheets 26 to separate. At this time, the ice slag and moisture can be smoothly discharged through the slag discharge hole 24. After that, a pair of flexible diaphragms 25 re-close under the action of their own elastic force and block the slag discharge hole 24. When the water cup 8 is stored inside the placement cylinder 7, the water cup 8 will squeeze the air storage bag 28 at the bottom. Then, the gas inside the air storage bag 28 is filled into the sealing air ring 27 through the pipeline, prompting the sealing air ring 27 to expand and closely fit with the surface of the water cup 8, improving the sealing degree of the placement opening 6, reducing the entry of external dust into the refrigerating chamber 4 through the placement opening 6, and at the same time reducing the overflow of cold air through the placement opening 6. By setting the water absorption film 29, when taking out the water cup 8 outward, the water absorption film 29 can wipe off the ice slag and moisture on the surface of the water cup 8, avoiding the problem of slipping when the staff takes it.
