Description

Technical Field

[0001] The invention relates to the technical field of steam-toasters, and in particular to an anti-falling device for steam-toasters. Background Art

[0002] Steaming and baking machines are generally used for thermal processing of poultry products in large food processing companies. By controlling the internal temperature, humidity and wind speed, cooking effects such as "steaming, browning, frying, and baking" can be achieved. With the use of the steaming and baking machine, when it is necessary to inspect or clean the inside, the machine cover needs to be raised. Since the entire machine cover weighs about 7 tons, when it is raised, the entire machine cover is suspended in the air. Although there are supporting equipment to support it, when people enter the equipment, they will have certain concerns, fearing that the machine cover will fall. In order to eliminate hidden dangers, a fall prevention device for the steaming and baking machine is often added.

[0003] For example, a spiral steam-oven anti-falling device disclosed on the patent website (authorization publication number: CN117284969B) can effectively support the hood and activate the anti-falling effect through the telescopic column, the protective square cylinder and the internal structure, and the telescopic column is supported at the four internal corners of the hood, which can effectively reduce the worries of maintenance personnel. However, in actual applications, the existing device only supports the hood through the telescopic column and the protective square cylinder. As the supporting time increases, the telescopic column may experience mechanical fatigue, thereby reducing the supporting effect on the hood, and the hood is still prone to shaking or falling. Therefore, in order to solve the problem that the existing device is difficult to support the hood more stably during use, and there is a risk of falling, we propose an anti-falling device for a steam-oven to solve the above problems.

[0031] When the device is actually used, when it is necessary to inspect the inside of the steam-bake machine, the hydraulic cylinder 4 can be opened first to make the steam-bake machine hood 5 slide upward inside the protective frame 3. Then, in order to ensure the fixed position of the steam-bake machine hood 5, the driving motor 612 can be turned on to rotate the first bidirectional screw 613. Under the action of the first limiting rod 615, the two sets of first concave movable plates 616 can be moved outward to make the first plug-in column 617 plug into the first plug-in hole inside the supporting bottom plate 1. At the same time, under the rotation of the first bidirectional screw 613, the first bevel gear 614 can be rotated to mesh with it.

With the cooperation of the abutment column 811 and the second spring 812, the position of the two-way ratchet pawl 88 can be fixed to ensure the limit of the rotation of the ratchet 87, and before lifting the steam-bake machine cover 5, the two-way ratchet pawl 88 can be fixed according to different When lifting is required, pull the lifting ring 73 outward to make the slide bar 72 slide inside the first connecting frame 71 to disengage the remaining gear 75 from the first gear 77. Then, the connecting hook 78 can be rotated to produce a corresponding angle. After reaching the required angle, release the lifting ring 73. Under the action of the first spring 74, the slide bar 72 can be restored to its initial position to restore the remaining gear 75 to the first gear 77. The angle of the connecting hook 78 is locked. With the cooperation of the locking anti-falling mechanism 6, the hook adjustment mechanism 7 and the auxiliary lifting mechanism 8, the steam-oven hood 5 can be prevented from falling during the maintenance of the steam-oven hood.
