Description

Technical Field

[0001] The utility model relates to the technical field of cantilever shelves, in particular to an expandable and adjustable cantilever shelf. Background Art

[0002] Cantilever racks are currently an important type of rack. Cantilever racks are suitable for storing long materials, ring-shaped materials, plates, pipes and irregular goods. The cantilever can be single-sided or double-sided. Cantilever racks have a stable structure and good load-bearing capacity.

[0003] In the existing cantilever racks, during the process of placing and storing pipes, the contact point between the pipes and the rack cantilever is small. Accidental contact by humans or handling machinery can easily cause the pipes to slide directly off the cantilever rack. Therefore, the existing cantilever racks lack the function of limiting the protection of the pipes during the storage process, posing a safety hazard. Summary of the invention

[0004] The purpose of the utility model is to provide an expandable and adjustable cantilever shelf. The application places the two ends of the pipe body inside the limit protection mechanism and uses the gravity of the pipe body itself to squeeze the buffer airbag. On the one hand, when the pipe body is placed in the semicircular fixing ring, it avoids hard contact with the semicircular fixing ring, causing damage to the semicircular fixing ring or the surface of the pipe body. On the other hand, the pneumatically driven clamping plate is displaced to limit and fix the outer wrapping of the pipe body, so as to avoid the pipe body from being accidentally touched by human or mechanical equipment and sliding onto the cantilever support frame during the subsequent storage process, thereby reducing the probability of safety hazards, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an expandable and adjustable cantilever shelf, comprising a fixed plate, both sides of the fixed plate are fixedly connected with columns, and the bottom of the column is vertically fixedly connected with a base support plate, the outside of the column is symmetrically fixed with a cantilever support frame, and the upper end surface of the cantilever support frame is equidistantly provided with a snap-fit ​​groove, and a limited position protection mechanism is arranged inside the snap-fit ​​groove;

[0006] The position limiting protection mechanism comprises a semicircular fixing ring fixedly connected in the engaging groove, and the upper end of the semicircular fixing ring is movably connected with a clamping plate.

[0007] Preferably, a movable groove is provided inside the semicircular fixing ring, and both ends of the top of the semicircular fixing ring are designed as open structures.

[0008] Preferably, the two clamping plates are designed in an arc-shaped structure, and one end of the clamping plate extends into the movable groove to be slidably connected to the semicircular fixing ring and match each other.

[0009] Preferably, one end of the clamping plate located in the movable groove is fixedly connected to an air plug, and a spring is fixed between the two air plugs.

[0010] Preferably, a buffer capsule is fixed to the inner upper side of the semicircular fixing ring, and air holes are provided at positions of the inner upper side of the semicircular fixing ring corresponding to the buffer capsule.

[0011] Preferably, the buffer capsule is connected to the movable groove through an air hole, and a rubber anti-slip pad is glued to the inner wall of the semicircular fixing ring.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The present application places both ends of the pipe body inside the limit protection mechanism and utilizes the weight of the pipe body itself to squeeze the buffer airbag. On the one hand, when the pipe body is placed in the semicircular fixing ring, it can avoid hard contact with the semicircular fixing ring, which can cause damage to the surface of the semicircular fixing ring or the pipe body. On the other hand, the pneumatically driven clamping plate is displaced to limit and fix the outer wrapping of the pipe body, so as to avoid the pipe body from being accidentally touched by human or mechanical equipment and sliding onto the cantilever support frame during subsequent storage, thereby reducing the probability of safety hazards.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 , the utility model provides a technical solution:

[0023] An expandable and adjustable cantilever shelf, comprising a fixed plate 1, both sides of the fixed plate 1 are fixedly connected with columns 2, and the bottom of the column 2 is vertically fixedly connected with a base support plate 4, the outside of the column 2 is symmetrically fixed with a cantilever support frame 3, and the upper end surface of the cantilever support frame 3 is equidistantly provided with a snap-fit ​​groove, and a limited position protection mechanism is arranged inside the snap-fit ​​groove;

[0024] The position limiting protection mechanism comprises a semicircular fixing ring 5 fixedly connected in the engaging groove, and a clamping plate 6 is movably connected to the upper end of the semicircular fixing ring 5 .

[0025] Specifically, a movable groove 8 is provided inside the semicircular fixing ring 5 , and both ends of the top of the semicircular fixing ring 5 are designed to be open.

[0026] Specifically, the two clamping plates 6 are designed to be arc-shaped, and one end of the clamping plate 6 extends to the inside of the movable groove 8 to be slidably connected to the semicircular fixing ring 5 and match each other.

[0027] Specifically, one end of the clamping plate 6 located in the movable groove 8 is fixedly connected to an air plug 11 , and a spring 10 is fixed between the two air plugs 11 .

[0028] Specifically, a buffer capsule 7 is fixed to the inner upper side of the semicircular fixing ring 5 , and air holes 12 are opened at positions corresponding to the buffer capsule 7 on the inner upper side of the semicircular fixing ring 5 .

[0029] Specifically, the buffer capsule 7 is connected to the movable groove 8 through the air hole 12, and a rubber anti-slip pad is glued to the inner wall of the semicircular fixing ring 5.

[0030] Working principle: During operation, the pipe body 9 is manually transported or transported to the upper end surfaces of the two cantilever support frames 3 by hoisting or mechanical equipment such as forklifts. The pipe body 9 corresponds to the semicircular fixing ring 5 in the locking groove on the cantilever support frame 3, and then the pipe body 9 is dropped, and the cushioning airbag is squeezed by the gravity of the pipe body 9 itself. On the one hand, when the pipe body 9 is placed in the semicircular fixing ring 5, it is prevented from hard contact with the semicircular fixing ring 5, causing surface damage to the semicircular fixing ring 5 or the pipe body 9. On the other hand, when the pipe body 9 falls, the cushioning airbag is squeezed, and the air inside the cushioning airbag is transported to the inside of the movable groove 8 through the air hole 12. Then the gas cooperates with the movable groove 8 and the air plug 11 to push the clamping plate 6 to move internally, and extends through the opening of the movable groove 8 to wrap and limit the outside of the pipe body 9, so as to prevent the pipe body 9 from being accidentally touched by humans or mechanical equipment and sliding onto the cantilever support frame 3 during the subsequent storage process, thereby reducing the probability of safety hazards.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
