Description

Technical Field

[0001] The utility model relates to the field of grain storage, and particularly relates to a placing rack for a gangway board in a granary. Background Art

[0002] With the increasing speed of grain circulation and the growing business volume year by year, the risks brought about by the increased ideological burden of individual management personnel in daily management will also intensify. The instability and uncertainty of work safety are significantly enhanced. If prevention is not timely and response is ineffective, the risks will be superimposed, evolved, and upgraded, posing a serious threat to the lives and safety of employees.

[0003] After the grain is put into storage, it needs to be leveled, and the grain condition needs to be inspected regularly. Walking directly on the grain surface is difficult, and trampling on the grain surface will make the grain surface uneven, requiring re-leveling, which will increase the workload of warehouse keepers. Therefore, in a granary, gangway boards are laid on the leveled grain surface to form a temporary walkway that can meet the needs of grain condition inspection. During the process of grain rotation in and out of the warehouse, the gangway boards on the grain surface need to be removed. If the gangway boards are frequently moved in and out of the warehouse, it will increase the management cost. If the removed gangway boards are temporarily placed on the beams in the warehouse, there is also the problem that the gangway boards are prone to falling, posing a great safety hazard. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a placing rack for a gangway board in a granary to solve the technical problem that it is difficult to handle the gangway board in a granary during the process of grain rotation in and out of the warehouse in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] An embodiment of a placement rack for gangplanks in a granary of the present utility model:

[0027] The specific structure of a storage bin walkway board placement rack is as follows Figures 1 to 3 shown, including a fixed frame 1, a movable frame 2, a locking mechanism 3, and a pulling mechanism 4. The fixed frame 1 is in the form of a rectangular frame and is fixed to the wall of the storage bin by expansion bolts. The movable frame 2 is rotatably mounted on the lower cross beam of the fixed frame 1 through a hinge 5. The movable frame 2 is also in the form of a frame to save materials and reduce the weight of the movable frame 2 itself.

[0028] The movable frame 2 can rotate relative to the fixed frame 1. Specifically, the movable frame 2 can be expanded to an open state extending outward and a retracted state of being folded and stored. The locking mechanism 3 includes an insertion nose 31 provided on the upper cross beam of the fixed frame 1. An insertion hole 32 is opened in the middle of the insertion nose 31, and a pin 33 is movably inserted into the insertion hole 32. After the movable frame 2 is folded, the pin 33 is located outside the movable frame 2, so that the movable frame 2 can be fixed in the retracted state to prevent it from accidentally unfolding. The horizontal projection area of the movable frame 2 in the retracted state is small and will not occupy too much space to affect the daily inspection of grain conditions. When the movable frame 2 is in the open state, the included angle between the fixed frame 1 and the movable frame 2 is not greater than 90 degrees to prevent the walkway board or other sundries on the movable frame 2 from sliding down from the outside.

[0029] In this embodiment, when the movable frame 2 is in the open state, it is completely embedded in the fixed frame 1 to further reduce the horizontal projection area of the placement rack in the retracted state.

[0030] The hinge 5 includes a first assembly part 51 and a second assembly part 52. The first assembly part 51 is fixed to the fixed frame 1, and the second assembly part 52 is fixed to the movable frame 2. An outwardly extending support plate 53 is provided on the first assembly part 51, and the support plate 53 forms a support structure for supporting the movable frame in the open state from below.

[0031] The pulling mechanism 4 is a metal chain arranged on both sides, with one end connected to the upper end of the fixed frame 1 and the other end connected to the free end of the movable frame 2. The length of the metal chain has been corrected in advance. When the movable frame 2 is in the open state, the metal chain is completely straightened, so that it can bear part of the gravity, avoiding the weight of the movable frame 2 and the heavy object on it from acting completely on the hinge 5, and also avoiding the problems of easy damage of the hinge 5 and unstable performance of the movable frame 2 caused thereby. The support plate 53 serves an auxiliary support function. In its normal state, it contacts the second assembly part fixed on the movable frame 2 and can provide a certain support force. After the metal chain breaks, it can also support the movable frame 2 in the short term, preventing the movable frame 2 from drooping downward and also preventing the heavy object on the movable frame 2 from directly falling. The support plate 53 is not used as a long-term main support structure, and its depth is small, so it will not cause bumps to the staff. In other embodiments, at least one of the ends of the fixed frame 1 and the movable frame 2 for connecting the metal chain is set in a form with an adjustable connecting end to adjust the length of the chain when the movable frame 2 is in the open state.

[0032] In other embodiments, the pulling mechanism 4 can also be Figure 2 the inelastic pulling rope shown.

[0033] In other embodiments, the support plate 53 can also be arranged on the second assembly part. When the movable frame 2 is folded and retracted, the support plate 53 folds upward with the movable frame 2 to reduce its horizontal projection area. When the movable frame 2 is opened, the support plate 53 contacts the first assembly part fixed on the fixed frame 1.

[0034] Taking Figure 2 the orientation shown as an example, taking the upper side of the movable frame 2 as the first side, the lower side as the second side, and the outer side (i.e., the free end side) as the third side. To further prevent the heavy object on the movable frame 2 from accidentally falling off, a flipping assembly 6 is provided at the free end of the movable frame 2. The flipping assembly 6 is rotatably installed on the second side of the movable frame 2. The flipping assembly 6 can be rotated to be close to the second side of the movable frame 2 for storage and can be flipped up to a state standing at the free end of the movable frame 2 when needed. After the flipping assembly 6 is erected, it can limit the outward displacement of the heavy object on the movable frame 2 and prevent the heavy object from falling off and hitting people. When the movable frame 2 is folded, the flipping assembly 6 is attached to the second side of the movable frame 2 to avoid affecting the passability of the surrounding space of the placement rack in the folded state due to the setting of the flipping assembly 6.

[0035] In this embodiment, the rotational connection structure between the flipping component 6 and the movable frame body 2 is a clearance fit, so the flipping component 6 can flip freely. To ensure that the flipping component 6 stands on the movable frame body 2 to play a limiting role, bolt perforations for bolt connection are correspondingly provided on the third side surfaces of the flipping component 6 and the movable frame body 2. When it is necessary to stand the flipping component 6 at the free end of the movable frame body 2 in the open state, the flipping component 6 and the movable frame body 2 can be fixed together with bolts. When it is necessary to fold and store the movable frame body 2, the bolts are removed, and the flipping component 6 can naturally fall under the action of gravity.

[0036] To facilitate screwing the nut, a hand-held force application part is fixed on the nut. The hand-held force application part can be a single rod provided on one side of the nut, or connecting ears symmetrically provided on both sides of the nut.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
