Description

Technical Field

[0001] The utility model relates to the technical field of gantry cranes, in particular to a gantry crane with an early warning function used in sauerkraut factories. Background Art

[0002] Sauerkraut factories are businesses that specialize in producing sauerkraut, using methods such as pickling and fermentation to meet market demand. The production process at a sauerkraut factory typically includes sourcing raw materials, pickling, fermenting, packaging, and selling. These factories not only produce sauerkraut, but may also produce other preserved foods, such as kimchi. The scale of production and product quality at sauerkraut factories vary by region and brand. Some well-known sauerkraut brands, through strict quality control and innovative processing technology, produce popular sauerkraut products that are exported throughout the country and even overseas. Furthermore, the development of sauerkraut factories has driven the development of the local economy, provided employment opportunities for local residents, and promoted the development of the agricultural and food processing industries.

[0003] In a sauerkraut factory, since items need to be transported back and forth, a gantry crane is usually installed to transport the items. When in use, the existing gantry crane usually adopts an electric hoist to drive the lifting rope. Since the load of the lifting rope itself is limited, if overweight items are lifted, the lifting rope will break, causing a safety accident. For this reason, the present application proposes a gantry crane with an early warning function for use in sauerkraut factories. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0029] The utility model provides a gantry crane with an early warning function for use in sauerkraut factories. The gantry crane uses a tension alarm to detect and alarm the load of the lifting rope, thereby realizing a load early warning function and preventing the lifting rope from breaking due to lifting overweight goods, thereby preventing safety accidents. A safety protection mechanism is also provided at the bottom of the support mechanism, which will alarm when the support mechanism falls and presses on people or objects, thereby improving safety effects. Figure 1-Figure 5 , including: a lifting mechanism 100, a supporting mechanism 200 and a safety protection mechanism 300.

[0030] The lifting mechanism 100 includes a hanger 110, an electric hoist 120, a lifting rope 130, a tension alarm 140, and a hook 150. The electric hoist 120 is mounted on the hanger 110, and the lifting rope 130 is mounted on the electric hoist 120. The lower end of the lifting rope 130 is connected to the hook 150 via the tension alarm 140.

[0031] Among them, the hanger 110 is a gantry, and the electric hoist 120 is used as a lifting equipment to perform moving and lifting operations. The electric hoist 120 is used to drive the lifting rope 130 to wind and release, so as to realize lifting and lowering. The goods are hung by the hook 150, and the tension alarm 140 is used to detect the load on the hook 150.

[0032] The support mechanism 200 is connected to the hook 150. Specifically, the support mechanism 200 includes a support frame 210, a pull rope 220, a hanging ring 230, a push switch 240, an audible and visual alarm 250, and a power supply 260. The top of the support frame 210 is connected to the hanging ring 230 via the pull rope 220, and the hanging ring 230 is connected to the hook 150. The bottom of the support frame 210 is provided with a push switch 240, an audible and visual alarm 250, and a power supply 260. The push switch 240, the audible and visual alarm 250, and the power supply 260 are connected in series.

[0033] Among them, the goods are placed in the support frame 210, and the support frame 210 is raised and lowered by the electric hoist 120 to complete the lifting operation. The push switch 240, the sound and light alarm 250 and the power supply 260 connected in series form a simple circuit structure. Pressing the push switch 240 connects the circuit and causes the sound and light alarm 250 to send out an alarm signal.

[0034] The safety protection mechanism 300 is disposed at the bottom of the support mechanism 200. The safety protection mechanism 300 includes a movable plate 310, a sleeve 320, a telescopic rod 330, a spring 340, and a push rod 350. Sleeves 320 are disposed at the four corners of the top of the movable plate 310. The telescopic rods 330 connected to the support frame 210 are inserted into the sleeves 320. The spring 340 is connected between the sleeves 320 and the support frame 210. A push rod 350 is disposed at the top of the movable plate 310, corresponding to the upper and lower sides of the press switch 240.

[0035] Among them, when the spring 340 is in the natural state, there is a gap between the movable plate 310 and the push switch 240, the sleeve 320 and the telescopic rod 330 form a telescopic structure, and the safety protection mechanism 300 rises and falls together with the support frame 210. As the support frame 210 continues to be lowered, the movable plate 310 will be pressed on the bearing platform. As the support frame 210 continues to be lowered, the spring 340 is compressed, and the distance between the movable plate 310 and the support frame 210 is reduced, so that the top rod 350 continues to approach the push switch 240, and finally presses the push switch 240, so that the push switch 240 is pressed. After being pressed, the push switch 240 causes the sound and light alarm 250 to send an alarm signal. If a person or object is pressed, an alarm can be issued in time.

[0036] Since sauerkraut itself contains water, mesh panels are used on all sides of the support frame 210, and evenly distributed water leakage holes are opened at the bottom of the support frame 210 to facilitate water leakage. The push switch 240, the sound and light alarm 250 and the power supply 260 are all waterproof parts to prevent the push switch 240, the sound and light alarm 250 and the power supply 260 from being damaged by contact with leaking water.

[0037] In order to prevent the push switch 240 from being damaged due to compression, a rubber pad is provided on the top of the push rod 350 so as to deform when subjected to pressure to prevent the push switch 240 from being crushed.

[0038] During specific use, items are placed in the support frame 210, and the electric hoist 120 is used to drive the lifting rope 130 to reel in and out, so as to achieve lifting and lowering. When lifting, the tension alarm 140 is used to detect the load on the hook 150 to prevent too many items from exceeding the bearing capacity of the lifting rope 130, thereby preventing the lifting rope 130 from being broken due to excessive use. When lowering, if the movable plate 310 of the safety protection mechanism 300 presses on a person or an item, the distance between the movable plate 310 and the support frame 210 is reduced, so that the top rod 350 continues to approach the press switch 240, and finally presses the press switch 240, causing the press switch 240 to be pressed. After being pressed, the press switch 240 causes the sound and light alarm 250 to send an alarm signal. If a person or an item is pressed, an alarm can be issued in time, thereby achieving the effect of safety warning.

[0039] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
