[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] The utility model provides a technical solution:

[0033] A lifting food delivery machine, please refer to Figures 1-10 , including a base plate bracket 10 and two guide rail brackets 11 symmetrically distributed and installed on the front side of the base plate bracket 10. Specifically, the guide rail bracket 11 can be fixedly connected to the base plate bracket 10 by bolts and nuts, and the guide rail bracket 11 can be U-shaped; the box bracket 3 is slidably connected along the height direction of the guide rail bracket 11, and guide shoes 30 are fixedly connected on both sides of the box bracket 3. The guide shoes 30 are slidably arranged along the height direction of the guide rail bracket 11, and a box 40 is installed on the front side of the box bracket 3.

[0034] The present invention also includes a traction mechanism for driving the box support 3 to lift and lower; the traction mechanism includes a guide wheel 21, a traction wheel 22, a motor 23 and a wire rope 24. The lower parts of the two guide rail supports 11 are fixedly connected to the support rod 20, and the two ends of the support rod 20 are respectively fixedly connected to the two guide rail supports 11. The guide wheel 21 passes through the support rod and is rotatably connected to the support rod 20. Specifically, the guide wheel 21 is rotatably connected to the support rod 20 through a bearing, and the motor 23 is installed on the top of the guide rail support 11 and drives the traction wheel 22 to rotate. Two horizontally arranged fixed plates 31 are welded on the rear side of the box support 3, and the wire rope 24 is wrapped around the guide wheel 21 and the traction wheel 22. The two ends of the wire rope 24 are connected to the rope head screw rod 25 and the compression spring 26 and are respectively fixedly connected to the two fixed plates 31.

[0035] Specifically, a motor base 12 is fixedly connected to the top of the guide rail bracket 11 , and the motor 23 is mounted on the motor base 12 by bolts. An opening is provided on the motor base 12 , and the wire rope 24 can pass through the opening; the traction wheel 22 is mounted on the output shaft of the motor 23 .

[0036] When the motor 23 is started, it can drive the traction wheel 22 to rotate, thereby driving the wire rope 24 to move back and forth around the traction wheel 22 and the guide wheel 21, and can drag the box bracket 3 to move up and down, thereby driving the box 40 to move up and down. When in use, the cooked dishes can be placed in the box 40 and lifted and lowered to achieve dish delivery.

[0037] The existing food delivery machines on the market generally use winch or synchronous belt type as traction power lifting. The winch (also known as winch / electric hoist) is a device that uses a drum and rope driven by human or mechanical power to complete the traction work. This structure is a single steel wire rope on the drum, and the steel wire ropes are overlapped and wound, which is easy to wear during operation, causing the steel wire rope to break. There is a risk of falling during use, posing a major safety hazard; the synchronous belt type food delivery machine uses a rubber synchronous belt for traction and lifting. Due to its own characteristics, the synchronous belt is prone to wear and weathering. After a certain period of use, there is also a risk of breakage. If it is stained with oil, it is easy to cause slipping during lifting, and there are certain safety hazards; the food delivery machine in the utility model solves the safety hazard risks and service life problems of the above-mentioned existing food delivery machines.

[0038] In addition, the present invention places the dishes to be delivered in the box 40, which does not expose the dishes directly to the outside. In this way, when the dishes are delivered in the lifting compartment, the dishes are not easily covered with dust. In addition, since the dishes are in the box, the box can slow down the heat dissipation of the dishes compared to placing the dishes on the delivery tray, thus preventing the dishes from getting cold.

[0039] The utility model can stick aluminum foil on the inner wall of the box body 40, and the aluminum foil can play a heat-insulating effect to a certain extent, further reducing the heat dissipation speed of the dishes in the box body.

[0040] A circular hole is provided on the box bracket 3, and the front end of the wire rope 24 passes through the circular hole; when N wire rope slots can be opened on the guide wheel 21 and the traction wheel 22, 1 or N wire ropes 24 can be set, which can enhance the stability and safety of lifting. N in the utility model refers to greater than or equal to 2.

[0041] A rope head screw 25 is fixedly connected to both ends of the wire rope 24. The wire rope 24 passes through the circular hole 15-20 cm at the top of the rope head screw 25, wraps around the circular hole at the top of the rope head screw 5, and then folds in half. The wire rope 24 passing through the rope head screw 25 and the main wire rope 24 are fixedly locked with a rope head. The fixing plate 31 is provided with a through hole, through which the rope head screw 25 passes. The rope head screw 25 is sleeved with a compression spring 26 and also includes a nut 27 threadedly connected to the rope head screw 25. The nut 27 fixes the compression spring 26 to compress it; to ensure that the wire rope has a certain degree of elasticity and elasticity. The function of the compression spring 26 is to tighten the wire rope 24 to maintain a certain degree of elasticity and elasticity, so that the wire rope 24 is tightly attached to the V-groove on the traction wheel 22, thereby increasing the friction between the wire rope 24 and the traction wheel 22, increasing the load, and eliminating the counterweight block, which is different from the conventional traction method.

[0042] Of course, when in use, the base plate bracket 10 can be installed on the wall; the wire rope can be composed of one or N pieces, which are wrapped around the traction wheel on the upper motor and the guide wheel at the lower end. After wrapping, they are respectively connected to the upper and lower ends of the box bracket 3 and the fixed plate 31 to form a wrap-around closed loop connection. After the motor 23 is started, one or N wire ropes and the V-groove on the traction wheel 22 form a downward pulling force and friction force, and act on the wire rope 24, thereby pulling the wire rope 24 to drive the pallet gantry to move up and down, so as to achieve the purpose of lifting and transporting items up and down. The function of the compression spring 26 is to tighten the wire rope 24 to maintain a certain degree of elasticity and elasticity, so that the wire rope 24 is tightly attached to the V-groove on the traction wheel 22, thereby increasing the friction between the wire rope 24 and the traction wheel 22, increasing the load, and canceling the counterweight block, which is different from the conventional traction method.

[0043] Guide rails 43 are installed on both sides of the box body 40 at the box body opening. Specifically, a mounting block 431 is fixedly connected to the guide rail 43, and the mounting block 431 is fixedly installed on the side wall of the box body 40 by bolts.

[0044] The box body 40 is provided with two upper and lower doors 42 at the opening. The doors 42 abut against one side of the opening of the box body 40. The two doors 42 can slide up and down along the guide rail 43. The upper door 42 slides upward, and the lower door 42 slides downward to open the box door 42.

[0045] Specifically, a sliding groove 432 is provided on one side of the guide rail 43 close to the box door 42 , and sliders are fixed on both sides of the box door 42 , and the two sliders are slidably disposed in the two sliding grooves 432 respectively.

[0046] An observation port is provided on the box door 42 , and a transparent window 421 is installed in the observation port, through which the situation inside the box body 40 can be observed.

[0047] A strip groove 420 is provided on the front side of the box door 42 to facilitate inserting fingers into and thus facilitate pushing and opening the box door 42.

[0048] Each guide rail 43 is provided with two upper and lower limit assemblies; when the box door 42 is opened, the upper limit assembly limits the upper box door 42 to prevent it from sliding down, and when the box door 42 is closed, the lower limit assembly limits the lower box door 42 to prevent the upper and lower boxes 42 from sliding down.

[0049] Specifically, the limiting assembly includes a limiting ball block 44 and a spring 45. Two upper and lower grooves 430 are opened on the side of the guide bar 43 close to the box door 42. Part of the limiting ball block 44 is slidably arranged in the groove 430. The spring 45 is arranged in the groove 430. The two ends of the spring 45 are respectively fixedly connected to the inner wall of the groove 430 and the limiting ball block 44.

[0050] See Figure 5The limiting ball block 44 includes a hemispherical portion and a cylindrical portion. The cylindrical portion is slidably arranged in the groove 430. When the box door 42 is pushed up and down by human power to slide and contact the hemispherical portion, the limiting ball block 44 is driven to move into the groove 430. At this time, the spring 45 is compressed. When the box door 42 moves out of the groove 430, the hemispherical portion of the limiting ball block 44 is pushed out of the groove 430 under the elastic force of the spring 45. When there is no human power to push the box door 42, the self-weight of the two box doors 42 cannot press the hemispherical portion to move.

[0051] When the doors 42 are opened, after the upper door 42 is pushed over the upper limiting ball block 44, the upper limiting ball block 44 can block the bottom of the upper door 42 for limiting the position, thereby preventing the upper door 42 from sliding down under its own gravity; when the doors 42 are closed, the lower limiting ball block 44 can block the bottom of the lower door 42 for limiting the position, thereby preventing both doors 42 from sliding down.

[0052] The box 40 also includes a storage plate 41, with guide blocks 410 fixedly connected to both sides. A plurality of guide grooves 400 are provided on both sides of the inner wall of the box body 40, and the guide blocks 410 slide and engage with the guide grooves 400. The storage plate 41 divides the interior of the box body 40 into two storage spaces, thereby forming a platform for placing dishes at the bottom of the inner wall and the top of the storage plate, making it easy to place more dishes.

[0053] When in use, the guide block 410 on the storage plate 41 can be aligned with the guide groove 400 at the corresponding height position as needed, so that the height of the two storage spaces inside the box 40 can be adjusted, which is convenient for rational use of space and placement of plates of different heights.

[0054] When the product is installed and used, there is a floor door for picking up food on each floor, and a transparent safety fence is set around the equipment, which is equivalent to the box running in a shaft. The transparent fence design makes it easy for users to observe the operating status of the box and facilitates subsequent inspection and maintenance work.
