[0019] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0020] Reference Figure 1-Figure 7 The present invention discloses a food logistics and emergency material storage warehouse, including a supporting wall 1, a plurality of roof brackets 2 and a plurality of roof panels 3. A plurality of receiving blocks 4 are respectively embedded at both sides of the top of the supporting wall 1. The receiving blocks 4 are welded and fixed to the steel bars in the supporting wall 1, and the upper surface of the receiving blocks 4 is flush with the upper surface of the supporting wall 1. At the same time, the receiving blocks 4 and the roof brackets 2 are arranged one by one.

[0021] Reference Figure 2 , Figure 3 , Figure 4 Rectangular positioning blocks 5 are vertically welded and fixedly connected to the two sides of the bottom of each roof bracket 2, and a rectangular positioning groove 6 is opened at the center position of the upper surface of each receiving block 4, and the positioning block 5 can be tightly inserted into the corresponding positioning groove 6, thereby limiting the installation position of the roof bracket 2, effectively reducing errors, and improving construction efficiency.

[0022] Reference Figure 3 , Figure 4The four inner walls of each positioning groove 6 are respectively provided with supporting grooves 7, and each supporting groove 7 is respectively connected with a locking rod 8 for horizontal sliding. At the same time, the four side walls of each positioning block 5 are respectively provided with locking grooves 9, and the locking rods 8 and the locking grooves 9 are arranged one by one.

[0023] Reference Figure 3 , Figure 4 A hydraulic control unit 10 is provided on each receiving block 4. When the positioning block 5 falls into the corresponding positioning groove 6, the hydraulic control unit 10 can control the corresponding four locking rods 8 to move synchronously, and make the ends of the four locking rods 8 close to each other be inserted into the corresponding locking grooves 9 respectively, so as to realize the locking between the positioning block 5 and the receiving block 4, and then realize the connection between the roof bracket 2 and the receiving block 4.

[0024] Since the roof bracket 2 and the receiving block 4 adopt a mechanical locking structure, there is no need to fix them by welding, and the operation is simpler and faster, which can not only reduce the burden on the staff, but also improve the construction efficiency. At the same time, compared with welding fixation, this design will not have problems such as cold welding and leaking welding, thereby ensuring the stability of the connection, thereby improving the stability of the use of the reserve warehouse. Of course, after the roof bracket 2 and the receiving block 4 are connected, the connection position of the roof bracket 2 and the receiving block 4 can also be repaired according to actual needs, so as to further improve the connection stability.

[0025] Reference Figure 3 , Figure 4 Each hydraulic control unit 10 includes a hydraulic chamber 101 disposed inside the receiving block 4. The hydraulic chamber 101 is located directly below the positioning groove 6 and is filled with a hydraulic medium. At the same time, a hydraulic piston 102 is vertically slidably connected in the hydraulic chamber 101, and the hydraulic medium is located below the hydraulic piston 102, so that the hydraulic piston 102 can squeeze the hydraulic medium.

[0026] Reference Figure 3 , Figure 4 The top of the hydraulic piston 102 is vertically fixedly connected with a control rod 103, the top of the control rod 103 extends to the inside of the positioning groove 6, and is vertically slidably connected with the receiving block 4. Four hydraulic channels 104 are arranged inside the receiving block 4, one end of the four hydraulic channels 104 is respectively connected with the hydraulic chamber 101, and the other end is respectively connected with the corresponding support groove 7, each hydraulic channel 104 is respectively provided with a one-way valve 105, and the one-way valve 105 is used to limit the hydraulic medium to enter only the support groove 7. At the same time, a control piston 106 is horizontally slidably connected in each support groove 7, and the ends of the four locking rods 8 that are away from each other are respectively connected with the corresponding control piston 106.

[0027] When the positioning block 5 falls into the positioning groove 6, the control rod 103 drives the hydraulic piston 102 to move downward under the pressure of the positioning block 5, and the hydraulic medium in the hydraulic chamber 101 enters the support groove 7 through the hydraulic channel 104, and pushes the control piston 106 to drive the corresponding locking rod 8 to move, and make the locking rod 8 abut against the side wall of the positioning block 5. As the positioning block 5 continues to fall, the pressure of the hydraulic medium gradually increases. When the locking groove 9 is aligned with the locking rod 8, the control piston 106 drives the locking rod 8 to continue to move under the pressure of the hydraulic medium. When the locking rod 8 is inserted into the locking groove 9, the connection between the positioning block 5 and the receiving block 4 can be achieved.

[0028] This design allows the roof bracket 2 to be automatically connected to the receiving block 4 during the installation process of the roof bracket 2 by the staff, effectively improving the linkage and coordination effect between the various components, improving resource utilization efficiency, while also saving time and reducing the burden on the staff.

[0029] Reference Figure 3 , Figure 4 , Figure 5 The locking rod 8 is cylindrical, and the locking rod 8 is rotatably connected to the corresponding control piston 106 through a sealed bearing. The inner side wall of each support groove 7 is fixedly connected with a guide column 11, and the side wall of each locking rod 8 is provided with a threaded guide groove 12, and the guide column 11 is slidably matched with the corresponding guide groove 12. When the locking rod 8 moves horizontally, the locking rod 8 can also rotate around its own axis to improve the guiding effect, so that the locking rod 8 can be smoothly inserted into the corresponding locking groove 9.

[0030] Reference Figure 3 , Figure 4 , Figure 5 The end of the locking rod 8 away from the corresponding control piston 106 is integrally formed with a connecting thread 13, and the inner wall of the locking groove 9 near the bottom of the groove is provided with a thread groove 14, the connecting thread 13 matches the thread groove 14, and the groove spacing of the thread groove 14 and the guide groove 12 is the same. When the locking rod 8 rotates, the connecting thread 13 can form a threaded connection with the thread groove 14, which improves the connection stability between the locking rod 8 and the positioning block 5, and also improves the locking stability, thereby achieving a stable connection between the roof bracket 2 and the receiving block 4.

[0031] Reference Figure 3 , Figure 4 , Figure 5 A retaining ring 15 is fixedly sleeved on the locking rod 8, a mounting groove 16 is circumferentially provided on the inner wall of the supporting groove 7, and a C-shaped elastic retaining ring 17 is embedded in the mounting groove 16. At the same time, a guide slope 18 is provided on the side of the retaining ring 15 away from the control piston 106.

[0032] When the locking rod 8 extends out from the supporting groove 7, the elastic snap ring 17 undergoes elastic deformation under the action of the guiding slope 18. When the connecting thread 13 forms a threaded connection with the thread groove 14, the backstop ring 15 passes over the elastic snap ring 17, that is, the elastic snap ring 17 is located between the control piston 106 and the backstop ring 15. At this time, the elastic snap ring 17 is reset to limit the retreat of the locking rod 8, thereby ensuring the stable connection between the locking rod 8 and the positioning block 5.

[0033] Reference Figure 3 , Figure 4 The bottom of the positioning groove 6 is horizontally fixed with a shear pin 19, and the side wall of the control rod 103 is provided with a shear groove 20, and the shear pin 19 is inserted into the shear groove 20. When the positioning block 5 falls into the positioning groove 6, the shear pin 19 can be sheared under the joint action of the positioning block 5 and the receiving block 4, and then the control rod 103 can move downward under the pressure of the positioning block 5.

[0034] This design can achieve the limiting of the control rod 103, the hydraulic piston 102 and other components, that is, to ensure that the control rod 103, the hydraulic piston 102 and other components are in the initial position, and the control rod 103 is subjected to external force to make the hydraulic medium enter the support groove 7, thereby ensuring that the locking rod 8 and other components are in the initial state, which is convenient for the staff to perform subsequent connection operations on the roof bracket 2 and the receiving block 4.

[0035] Reference Figure 2 , Figure 6 Each roof bracket 2 is fixedly connected to both sides with reinforcing rods 21, and the bottom of each reinforcing rod 21 is vertically fixedly connected with a reinforcing column 22. Each receiving block 4 is provided with a reinforcing groove 23, and the reinforcing column 22 can be tightly inserted into the corresponding reinforcing groove 23.

[0036] When the positioning block 5 falls into the positioning groove 6, the reinforcing column 22 also falls into the reinforcing groove 23. At this time, the reinforcing rod 21 can support the roof bracket 2, thereby improving the structural strength between the roof bracket 2 and the receiving block 4, thereby improving the structural stability of the storage warehouse. Of course, the reinforcing rod 21 and the receiving block 4 can be repaired by welding as needed in the later stage, so as to further improve the connection stability.

[0037] Reference Figure 1 , Figure 7 The roof support 2 is a triangular structure, each roof panel 3 is in an inverted V shape, and the roof panels 3 are connected to the corresponding roof support 2 by fasteners, so that multiple roof panels 3 can form an inverted V-shaped roof to improve the diversion effect of rain and snow.

[0038] Reference Figure 1 , Figure 7Half of the roof panels 3 are provided with step portions 24 on both sides, and the other half of the roof panels 3 are provided with step grooves 25 on both sides. The roof panels 3 provided with step portions 24 and step grooves 25 are arranged at intervals, and the step portions 24 can fit tightly with the corresponding step grooves 25 to achieve a tight overlap of multiple roof panels 3, while also improving the sealing effect between two adjacent roof panels 3.

[0039] Reference Figure 1 , Figure 7 Each step portion 24 is respectively penetrated with a plurality of glue injection holes 26, and the sealing foam can be injected into the connection position of the two roof panels 3 through the glue injection holes 26, thereby further improving the sealing effect between the two adjacent roof panels 3 and reducing the risk of roof water seepage.
