DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0024] like Figure 1-Figure 6 As shown, a prefabricated box beam grouting powder storage and retrieval device includes three parts: a base 1, a conveying unit 2 and a stacking storage and retrieval mechanism; the base 1 has a corresponding supporting force; the conveying unit 2 is located on one side of the base 1 and is used to feed materials to the stacking storage and retrieval mechanism; the stacking storage and retrieval mechanism includes a lifting unit and a bearing unit, and the bearing unit is located above the lifting device to store materials. The conveying unit 2 feeds the material to the lifting unit, and the lifting unit lifts the material body and sends it to the bearing unit to complete the regular storage of the grouting material.

[0025] In some preferred embodiments, the lifting unit is arranged on the base 1, and loading and unloading operations are performed between the conveying unit 2 and the carrying unit; in the present embodiment, it should be noted that a side wall of the frame 17 close to the conveying unit 2 is set as a front side wall, and a side wall opposite to the front side wall is set as a rear side wall, and the front side wall is provided with an opening for the material feeding body to enter and exit the frame 17, and limiting clamps 3 are respectively installed at the positions corresponding to the rear side walls on both sides of the opening, and the bearing body 13 of the material body is used to limit the position during loading and unloading. When loading, the bagged grouting material is placed in the bearing body 13, and the material is fed to the opening of the frame 17 through the conveying unit 2. At this time, the bearing operation position of the lifting device is raised to the conveying height of the conveying unit 2, and the lifting device receives the material at the opening. The bearing body 13 can be pushed to the bearing operation position of the lifting device, and the lifting device lifts the bearing body 13 and the grouting material carried by the bearing body 13 to the bearing unit for storage.

[0026] In some preferred embodiments, specifically, the lifting unit includes a hydraulic lifting mechanism 7 and a support platform 8 arranged at the lifting end of the hydraulic lifting mechanism 7, and the support platform 8 is provided with a limit stop column 9 on the side away from the conveying unit 2, and the front end of the direction in which the load-bearing body 13 is pushed to the support platform 8 is limited to prevent the load-bearing unit from slipping. In addition, the support platform 8 can be provided with limit columns on both sides of the direction in which the load-bearing body 13 is pushed to limit the bottom of the load-bearing body 13.

[0027] In some preferred embodiments, the bearing unit is erected above the base 1 through the frame 17, and is located above the lifting unit, for carrying the material body. The bearing unit is arranged in multiple groups and arranged at intervals up and down. Specifically, the bearing unit includes a fixed shaft 4, a support block 5 and a limit shaft 6; the fixed shaft 4 is fixed between the front and rear sides of the frame 17, and is respectively located on both sides of the material conveying direction, and has corresponding supporting force; the support block 5 is rotatably mounted on the fixed shaft 4, and is arranged at intervals along the material conveying direction. The support block 5 is provided with a supporting working surface 10, and the supporting working surface 10 is provided with a step matching the bearing body 13; the limit shaft 6 is arranged between the front and rear sides of the frame 17, and is respectively arranged on both sides of the material conveying direction and located on the rear side of the fixed shaft 4. The limit shaft 6 can be located at a predetermined position above the rear side of the fixed shaft 4. The predetermined position of the limit shaft 6 is set to limit the flipping angle of the support block 5. The limit shaft 6 is connected to the driving component so that the limit shaft 6 can be lifted and lowered to a corresponding height along the side wall of the frame 17.

[0028] It should be noted that, in the initial state, the support block 5 is in a horizontal position through the torsion spring, that is, the supporting working surface is in a horizontal position; after the external force of the support block 5 is removed, the supporting working surface of the support block 5 can be reset to the horizontal position.

[0029] Among them, in this embodiment, the driving component is placed on the front side wall of the frame 17, and is placed in a shell on one side of the opening. The placement shells are symmetrically distributed in pairs on the front and rear sides of the frame 17, and the placement shells are connected with the frame 17 at the connection. The front and rear ends of the limit shaft 6 are respectively extended into the corresponding placement shells through the connection. Any end of the limit shaft 6 extended into the placement shell is connected to the driving component. The driving component can be a hydraulic or electric lifting rod 11. One end of the limit shaft 6 is fixedly connected to the lifting end of the lifting rod 11 through a fixed body. When the lifting end is raised or lowered, the height of the limit shaft 6 is changed.

[0030] It should be noted that, in this example, the material-carrying container is a carrying body 13 , and the carrying body 13 includes a support body 14 at the bottom, a baffle 15 on the support body 14 , and a fixed edge 16 at the top edge of the support body 14 .

[0031] When the limit shaft 6 reaches a predetermined height, the flipping of the support block 5 can be limited, so that the support working surface 10 of the support block 5 is in a horizontal state when subjected to downward pressure, and at this time, the support body 13 can be stably supported. After the limit shaft 6 continues to rise at the predetermined position, the support working surface 10 of the support block 5 flips downward, releasing the support body 13, and the support body 13 falls to unload the material.

[0032] It should be noted that the limit shaft 6 can be connected to the driving component separately, so that the limit shaft 6 can be raised and lowered separately in sequence. When unloading (when unloading is required, the two sides of the load-bearing body 13 are respectively placed on the supporting working surfaces 10 of the corresponding support blocks 5), the lifting device rises to the corresponding height, the limit shaft 6 rises, and the support block 5 flips under the pressure of the gravity of the load-bearing body 13. The load-bearing body 13 falls on the supporting platform 8 of the lifting device, and the lifting device descends to the opening, a position level with the conveying height of the conveying unit 2, and the load-bearing body 13 is pushed into the conveying unit 2, and the conveying unit 2 transports the material to the outside. When loading, the corresponding driving components (lifting rod 11) of the limit shaft 6 are controlled respectively to make the limit shaft 6 at a predetermined height. When the load-bearing body 13 presses down the support block 5, the support block 5 is prevented from continuing to flip over, thereby stably supporting the load-bearing body 13 (the load-bearing body 13 first goes up, and when it touches the support block 5, the support block 5 flips over, so that the fixed edge 16 of the outer wall of the load-bearing body 13 can continue to go up to above the support working surface 10 of the support block 5, and then the load-bearing body 13 is lowered, and the fixed edge 16 presses down the support working surface 10 of the support block 5 until it is pressed down to a horizontal position, and the limit shaft 6 is against the top of the other end of the support block 5 to prevent the support working surface 10 from continuing to fall, thereby stably supporting the load-bearing body 13).

[0033] It should be noted that multiple limit shafts 6 can be simultaneously connected to the lifting end of a lifting rod 11. When loading, the limit shaft 6 is controlled to the corresponding height so that when the supporting working surface 10 of the support block 5 is under pressure, the limit shaft 6 is limited to the top of the support block 5 to prevent the supporting working surface 10 from flipping downward. The lifting device lifts the load-bearing body 13. When the load-bearing body 13 ascends to the height of the support block 5, it continues to ascend, pushing one end of the supporting working surface 10 of the support block 5 to continue to ascend. After the fixed edge 16 of the load-bearing body 13 exceeds the support block 5, the support block 5 is reset, and the load-bearing body 13 descends. The fixed edge 16 resists the supporting working surface 10 erected on the support block 5 and presses down the supporting working surface 10 of the support block 5 until the supporting working surface 10 of the support block 5 cannot be further pressed down under the action of the limit shaft 6, thereby realizing the loading and storage of the load-bearing body 13 and the carried materials.

[0034] The specific use is as follows: the limit shaft 6 can be connected to the lifting rod 11 respectively (the housing is divided into corresponding lifting control chambers 12 according to the number of limit shafts 6, and the corresponding lifting rod 11 is arranged in the lifting control chamber 12. The telescopic end of the lifting rod 11 is fixedly connected to one end of the limit shaft 6. The corresponding lifting control chamber 12 is also arranged on the rear side of the frame 17. The control chamber is connected to the frame 17. The lifting rod 11 is arranged in the control chamber, and the other end of the limit shaft 6 is fixed to the telescopic end of the lifting rod 11). After starting the lifting rod 11, the limit shaft 6 rises and falls synchronously with the telescopic end of the lifting rod 11, changing the vertical distance between the limit shaft 6 and the fixed shaft 4. When it is at the highest point, the support working surface 10 of the support block 5 can be turned downward to release the bearing body 13; when it is at the lowest point, the support block 5 is against the top of one side of the support block 5, so that the support working surface 10 on the other side is maintained in a horizontal support working position.

[0035] When loading, make the limit shaft 6 at the lowest position; place the bagged grouting material in the bearing body 13; start the conveying unit 2, place the bearing body 13 on the conveying unit 2, and the conveying unit 2 feeds the material to the opening; raise the support platform 8 to the level position of the conveying unit 2, and the bearing body 13 is pushed to the support platform 8, and the support platform 8 rises. When the bearing body 13 goes up, it contacts the bottom of one end of the supporting working surface 10 of the support block 5, and pushes one end of the supporting working surface 10 of the support block 5 upward. After the fixed edge 16 is located above the support block 5, one end of the supporting working surface 10 of the support block 5 falls back, and the other end abuts against the bottom of the limit shaft 6. At this time, the bearing body 13 is lowered, and the fixed edge 16 contacts the supporting working surface 10, and is supported by the supported working surface 10 at the corresponding position. Then load the material from top to bottom.

[0036] When unloading materials, unload them from bottom to top in sequence, control the corresponding limit shaft 6 to the highest point, and make the support platform 8 of the lifting device rise and fall to the bottom of the load-bearing body 13 of the unloaded materials; at this time, one end of the supporting working surface 10 of the support block 5 is pressed down by the fixed edge 16 of the load-bearing body 13 to flip over, and the load-bearing body 13 loses its supporting force and falls onto the support platform 8 of the lifting device, and the support platform 8 carries the load-bearing body 13 down to the conveying height of the conveying unit 2, and the conveying unit 2 is started in reverse to push the load-bearing body 13 to the conveying unit 2, and the grouting material in the load-bearing body 13 is delivered to the outside.

[0037] Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents. In short, if those skilled in the art are inspired by them and design structural modes and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they shall all fall within the scope of protection of the present invention.
