Description

Technical Field

[0001] This utility model relates to the field of protection technology for high-altitude operations in grain warehouses, and in particular to a protection device for high-altitude operations in grain warehouses. Background Technology

[0002] Since ancient times, granaries have been an important part of human civilization. With the development of agriculture, people began to need to store surplus grain for unforeseen circumstances, and thus granaries gradually emerged. In modern society, granaries not only store grain but also bear the important responsibility of ensuring national food security. The design and management of granaries need to consider various factors such as grain storage, pest control, moisture prevention, and fire prevention to ensure the quality and quantity of grain.

[0003] When grain is ready for the next stage of storage after being released from the grain warehouse, a covering film is usually installed on the inner wall surface of the grain warehouse for moisture protection. However, when installing the moisture-proof film, strip fasteners are used to fix the upper part. Therefore, warehouse staff need to use a tall ladder to install the strip fasteners. The protective parts on the ladder alone cannot effectively guarantee the safety of warehouse staff working at height, and there is still a certain risk of falling. Utility Model Content

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Reference Figure 1-5 As shown, a protective device for high-altitude operations in a grain silo is characterized by: a fixed plate 1, a connecting plate 2, a locking element 3, a steel rope 4, and a traction element 5; several fixed plates 1 are provided and fixedly connected to the four walls inside the grain silo; several fixed plates 1 are located on the same horizontal plane; a connecting plate 2 is detachably connected to the side of several fixed plates 1 away from the wall; a locking element 3 is fixedly connected to the connecting plate 2; the steel rope 4 passes through several locking elements 3 and is fixed by the locking elements 3; a traction element 5 is detachably connected to the steel rope 4.

[0028] It should be noted that the fixing plate 1 is stably fixed to the four walls inside the grain silo, so that the other components can also be stably connected; the connecting plate 2 is detachably connected to the fixing plate 1 through bolts set around the fixing plate 1 to ensure the connection strength; the locking part 3 can stably fix the steel rope 4 inside the locking part 3 to prevent it from loosening or falling off; the steel rope 4 is equipped with a traction part 5, which can be separated from the steel rope 4. One end of the traction part 5 is detachably connected to the steel rope 4, and the other end is connected to the safety device on the worker, effectively ensuring the safety of the worker.

[0029] Specifically, the locking component 3 includes a first seat 31, studs 32, a clamping block 33, and a second seat 34. The first seat 31 is fixedly connected to the connecting plate 2. Studs 32 are fixedly connected to both ends of the first seat 31. One end of the clamping block 33 is fitted against the first seat 31, and the other end is fixedly connected to the second seat 34. Both ends of the second seat 34 are threaded through holes onto the two studs 32 and fixed with nuts. When the nuts are tightened, the clamping block 33 is tightly fitted against the first seat 31. Both the first seat 31 and the clamping block 33 have corresponding semi-circular holes, and the two semi-circular holes together form a horizontal through hole 35. The first seat 31 can be connected to the connecting plate 2 to provide support. The studs 32 can tightly fit the clamping block 33 and the second seat 34 against the first seat 31 with nuts. The through hole 35 can be used to thread a steel rope 4. The diameter of the steel rope 4 is less than or equal to the inner diameter of the through hole 35 to ensure smooth threading.

[0030] Specifically, in order to prevent the steel rope 4 from swaying and rubbing back and forth between the two ends of the through hole 35 during operation, which would cause damage to the steel rope 4, chamfers 36 are provided at both ends of the through hole 35.

[0031] Specifically, the traction component 5 includes buckles 51, connecting rings 52, and a flexible rope 53. The two ends of the flexible rope 53 are connected to two buckles 51 via the connecting rings 52. The buckles 51 facilitate the connection of one end of the traction component 5 to the steel rope 4 and the other end to the worker's safety device.

[0032] Specifically, a slotted buckle 6 is vertically fixed to the connecting plate 2; the slotted buckle 6 can prevent the position of the steel rope 4 from being restricted when the locking member 3 is unstable, so as to prevent it from falling off and affecting the installation of the strip-shaped fixing member; the slotted buckle 6 includes a metal strip 61 and a tightening member 62; the lower end of the tightening member 62 can move up and down relative to one end of the metal strip 61, and the upper end is threadedly connected to the other end of one end of the metal strip 61. The metal strip 61 can be made into a slot shape to facilitate the threading of the steel rope 4; the tightening member 62 can remove the steel rope when it is opened, and restrict the position of the steel rope 4 when it is tightened.

[0033] Specifically, to protect the safety of staff and enhance the stability of integrity, the connecting plate 2 and the slotted buckle 6 are welded together. The connecting plate 2 and the locking component 3 are also welded together.

[0034] The working principle of this utility model:

[0035] A predetermined number of fixing plates 1 are installed on the four walls inside the grain silo. In this application, connecting plates 2, locking parts 3, and slotted buckles 6 are welded together and then installed on several fixing plates 1. During installation, a single steel rope can be used, or four steel ropes 4 can be set according to the four sides of the grain silo and threaded through the locking parts 3 and slotted buckles 6. The specific choice can be made according to the size of the grain silo used. This application adopts the latter setting. After installation, when workers stand on the ladder to install the strip-shaped fixing parts, they can connect their safety device to one end of the traction component 5, and the other end of the traction component 5 to the steel rope 4. After the connection is completed, the strip-shaped fixing parts are installed. When the upper end of the traction component 5 moves to the locking parts 3 and slotted buckles 6, the traction component 5 can be removed from the steel rope 4, bypassed around the locking parts 3 and slotted buckles 6, and then reconnected. This application effectively ensures the safety of workers installing strip-shaped fixing parts at height, effectively improves the safety of warehouse management personnel working at height, and allows workers to focus more on installing strip-shaped fixing parts, thus improving installation efficiency.

[0036] By attaching the upper buckle to the steel rope 4 and allowing it to slide left and right, the traction component 5 and the steel rope 4 are kept perpendicular to each other at all times when the workers are working. This ensures that if a danger occurs, the workers will be pulled by the traction component 5, thus preventing accidents.

[0037] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
