Description

Technical Field

[0001] The utility model relates to the field of transport equipment, in particular to a dish lifting device. Background Art

[0002] With the increasing labor costs, the delivery of dishes has also changed from traditional pure manual handling to semi-automatic delivery to reduce the amount of labor in restaurants and reduce the cost of restaurant operation. For example, the delivery robots that are currently used more in dining elevators and hotels have small capacity and low handling efficiency. For example, Chinese patent application No. 2015207292091 discloses a windmill-type three-dimensional conveying device, which is used to lift and transport dishes. The dishes are placed on a plate, and the plate is placed on the conveying device and transported upward or downward. Due to the limited volume of the plate, the number of dishes transported each time is limited. At the same time, it is necessary to arrange one person at the dish-taking port on each floor to manually bring the dishes to the table. Only one or several dishes can be served at a time, which is inefficient. For some restaurants with a large flow of customers, it is necessary to quickly serve dishes in batches. For this reason, it is necessary to develop a device that can deliver dishes in batches to improve the efficiency of serving dishes and reduce labor costs. Utility Model Content

[0022] Examples, such as Figures 1 to 10As shown, a dish lifting device comprises a lift 1 and a dining car 2, wherein the lift 1 drives the dining car 2 to move up and down.

[0023] The elevator 1 includes a chassis 17, on which a group of side doors 171 corresponding to the food-taking floors are arranged, and the dining cart 2 enters and exits from the side doors 171. A frame 11 is arranged in the chassis 17, a driving shaft 12 and a driven shaft 13 are arranged on the frame 11 up and down, and two revolving conveying chains 14 are arranged between the driving shaft 12 and the driven shaft 13. A group of suspension components 15 for driving the dining cart 2 to move up and down is arranged between the two revolving conveying chains 14, and a pressure stop bar 16 is arranged below the suspension component 15. The upper part of the dining cart 2 is suspended and supported on the suspension component 15, and the lower part is pressed on the pressure stop bar 16, so as to ensure that the dining cart 2 remains stable and does not shake when being transported up and down. The dining cart 2 is provided with a suspension part 21 that cooperates with the suspension component 15.

[0024] Specifically, the suspension assembly 15 includes a transverse guide rail 151 and a baffle 152 disposed outside the transverse guide rail 151. Both ends of the transverse guide rail 151 are fixed to the rotary conveyor chain 14. The suspension portion 21 is a slide rail adapted to the transverse guide rail 151. To improve the smoothness of transportation, a rolling bearing may be disposed in the transverse guide rail 151 or a rolling bearing or a roller may be disposed at the bottom where the suspension portion 21 cooperates with the transverse guide rail 151.

[0025] The dining cart 2 is provided with a multi-layered placement platform 22, the hanging part 21 is provided on both sides of the dining cart 2 in the length direction and is located in the upper half of the dining cart 2, and a group of universal wheels 23 are provided at the bottom of the dining cart 2 for easy horizontal movement. In order to ensure the smooth entry of the dining cart 2 and prevent the dining cart 2 from hitting the end of the transverse guide rail 151, a lower guide piece 153 inclined downward is provided at one end of the transverse guide rail 151 relative to the side door 171, and a side guide piece 154 is provided on the side of one end of the transverse guide rail 151 relative to the side door 171, and the side guide piece 154 is provided on the frame 11.

[0026] Since the kitchen is usually located on the lowest level, in order to ensure the stability of the dining cart entering the lifting device when it is full of dishes and to ensure the accuracy of the position, a guide positioning rail 3 is provided on the bottom floor corresponding to the bottom of the rotary conveyor chain 14, and a positioning wheel 24 adapted to the guide positioning rail 3 is also provided on the dining cart 2. The positioning wheel 24 is pushed into the guide positioning rail 3 to realize the positioning of the dining cart 2 in the left and right directions. At the same time, a positioning beam 25 is provided at the front end of the dining cart 2. The front end mentioned in the utility model refers to the front end in the forward direction when the dining cart is pushed into the elevator. A locking positioning device 4 for locking the dining cart 2 into position is also provided on the floor corresponding to the bottom of the rotary conveying chain 14. The locking positioning device 4 includes a vertical baffle 41 and a limit strip 42 arranged along the forward direction of the dining cart 2. The rear end of the limit strip 42 is provided with a propulsion slope 421, and one end of the propulsion slope 421 is provided with a limiting step 422. The width between the limiting step 422 and the vertical baffle 41 is adapted to the positioning beam 25, and the positioning beam 25 is inserted between the limiting step 422 and the vertical baffle 41 to achieve positioning; a tension spring 43 is provided between the front end of the limit strip 42 and the ground. When the dining cart 2 enters, the positioning beam 25 at the front end of the dining cart 2 is pressed on the propulsion slope 421. Under the pressure of the dining cart 2, the tension spring 43 is stretched, and the dining cart continues to move forward. When the positioning beam 25 passes over the limiting step 422 and hits the vertical baffle 41, the tension spring 43 is retracted, causing one end of the propulsion slope 421 to move upward, and the limiting step 422 limits the other end of the positioning beam 25, thereby realizing the positioning of the dining cart 2 in the front and rear directions.

[0027] Through the structure of the utility model, the one-time lifting and conveying of batch dishes can be realized, which greatly improves the efficiency of conveying. In addition, the utility model can also be applied to the conveying of other products, such as medicines, express parcels, etc., and is not limited to the conveying of dishes.

[0028] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
