Technical Field

[0001] This utility model relates to the technical field of mortar transportation, and in particular to a mortar transportation system for prefabricated building factories. Background Technology

[0002] With the rapid development of prefabricated buildings in my country, the assembly rate is gradually increasing, and the proportion of factory decoration in prefabricated buildings is becoming larger and larger.

[0003] Mortar is a commonly used material in decoration, and its transportation is a crucial step. Traditional mortar transportation methods suffer from low efficiency and high costs, making it difficult to meet the needs of prefabricated building factories for efficient and convenient mortar transportation. Therefore, this utility model proposes a novel, simple mortar transportation device for prefabricated building factories, aiming to solve the problems existing in the prior art and improve the efficiency and convenience of mortar transportation.

[0004] Traditional mortar transportation typically relies on manual handling or simple mechanical tools such as wheelbarrows. These methods present numerous inconveniences and limitations on construction sites. First, manual handling is not only labor-intensive and inefficient, but also prone to worker fatigue and accidents, especially when handling large quantities of mortar, where safety risks increase significantly.

[0005] Alternatively, mortar can be transported using a dedicated mortar transport vehicle. However, since mortar transport vehicles are a complete product, they cannot be obtained from the existing equipment on the construction site, resulting in relatively high procurement costs.

[0030] To better explain and facilitate understanding of this utility model, the following description is provided in conjunction with the appendix. Figures 1-3 This invention will be described in detail through specific embodiments. Wherein, directional terms such as "upper" and "lower" are used in this document. Figure 1 The orientation is used as a reference. "Front," "Back," "Inner," and "Outer" are references. Figure 2 The direction indicated in the middle.

[0031] Example 1:

[0032] Reference Figures 1-3This utility model provides a mortar transportation system for prefabricated building factories, including a mortar storage device 1, a forklift 2, and a locking component 3. The mortar storage device 1 includes a mortar tank 11 and a frame 12. The mortar tank 11 is suitable for storing and releasing mortar, and the frame 12 is suitable for supporting the mortar tank 11. The frame 12 has a tube 12a. The forklift 2 includes fork teeth 21, and the tube 12a is clearance-fitted with the fork teeth 21. The fork teeth 21 can be inserted into the tube 12a so that the forklift 2 can lift the mortar storage device 1. The locking component 3 is suitable for selectively locking the fork teeth 21 after they are inserted into the tube 12a. When the fork teeth 21 are inserted into the tube 12a and the locking component 3 locks the fork teeth 21, the mortar storage device 1 and the forklift 2 form an integrated transportation unit.

[0033] In this embodiment, the mortar transportation system within the prefabricated building plant achieves efficient and safe transfer of mortar on the construction site. A pipe 12a is located at the bottom of the frame 12, its position perfectly aligned with the fork tines 21 of the forklift 2, ensuring precise docking. The forklift 2, acting as a power transport unit, has its fork tines 21 extending horizontally into the pipe 12a on the frame 12. Through the interaction of the fork tines 21 and the pipe 12a, the entire mortar storage device 1 is lifted and transported. A locking element 3 ensures stability and safety during transport, preventing the fork tines 21 from dislodging due to vibration, bumps, or tilting, thus avoiding the mortar tank 11 from tipping over or falling off. Once the locking element 3 completes its locking action, the mortar storage device 1 and the forklift 2 form a rigidly connected integrated transport unit, significantly improving the stability and operational safety of the transport process.

[0034] Once forklift 2 reaches its destination, simply releasing the locking mechanism 3 allows for the smooth extraction of the fork 21, ensuring precise positioning of the mortar container 11. This system is suitable for various construction scenarios, demonstrating excellent practicality and flexibility, particularly in situations with limited space or frequent transfers. The entire system is simple in structure and easy to operate, effectively improving the automation and efficiency of mortar transportation while reducing the safety risks associated with manual handling.

[0035] The locking member 3 includes a push rod 31 and a push block 32. The push rod 31 is longitudinally slidably connected to the outside of the insertion tube 12a, and the push block 32 is laterally slidably connected to the side wall of the insertion tube 12a. The push block 32 extends into the insertion tube 12a to form a pressing part of the fork tooth 21. The rear end of the push rod 31 forms a first inclined surface 31a, and the outer side of the push block 32 forms a second inclined surface 32a. When the fork tooth 21 is inserted into the insertion tube 12a, and the forklift 2 presses against the front end of the push rod 31, the push rod 31 can slide backward and make the first inclined surface 31a and the second inclined surface 32a cooperate, thereby making the push block 32 slide into the insertion tube 12a so that the pressing part can press and lock the fork tooth 21.

[0036] This locking mechanism achieves automatic locking after the fork 21 is inserted through mechanical linkage, improving the convenience and safety of operation. The push rod 31 and the push block 32 achieve force transmission and direction conversion through the cooperation of inclined surfaces. The push rod 31 is slidably disposed on the outside of the insertion tube 12a along the longitudinal direction, and its axis is parallel to the length direction of the insertion tube 12a. The whole can slide back and forth along its own axis under the action of external force.

[0037] The pusher block 32 is installed laterally in the guide groove on the side wall of the insertion tube 12a, and can slide radially along the insertion tube 12a. A portion of it extends into the internal space of the insertion tube 12a to form a pressing part for pressing the fork tooth 21.

[0038] As the fork 2's fork tines 21 insert into the insertion tube 12a, the fork 2's front end contacts the front end of the push rod 31, applying continuous pushing force and causing the push rod 31 to slide backward. At this time, the first inclined surface 31a at the rear end of the push rod 31 moves accordingly and contacts and interacts with the second inclined surface 32a on the outer side of the push block 32. Due to the relative sliding between the two inclined surfaces, the longitudinal backward movement of the push rod 31 is converted into the lateral displacement of the push block 32, meaning the push block 32 slides into the insertion tube 12a under the driving force of the inclined surfaces. As the push block 32 moves inward, its pressing part extending into the insertion tube 12a gradually approaches and eventually presses tightly against the side wall of the inserted fork tines 21, thus forming a strong clamping force and effectively preventing the fork tines 21 from loosening or dislodging during transportation due to vibration or external forces.

[0039] The locking process is entirely triggered by the insertion of the fork 21, requiring no additional manual operation or external power source, achieving an automated "plug and lock" locking effect. When it is necessary to unload the mortar collection device 1, the operator can retract the forklift 2 after the mortar collection device 1 has been lifted, so that the forklift 2 no longer presses against the push rod 31, thereby releasing the pressure of the pressing part on the fork 21. The entire locking mechanism is a purely mechanical structure, with a compact structure, sensitive response, and high reliability. It can work stably in complex construction environments, significantly improving the overall safety and operational efficiency of the mortar transportation system in prefabricated building plants.

[0040] In summary, the mortar transportation system in the prefabricated building plant can be directly obtained by modifying the mortar tank 11 and using a forklift 2. The modification method is simply to add a pipe 12a and a locking part 3 to the mortar tank 11 and use it with a forklift 2 commonly used on construction sites. Compared with the traditional method of transporting mortar by handcart, it is more efficient. Compared with a dedicated mortar transport vehicle, it is less expensive. In other words, this utility model provides a technical solution that combines cost and mortar transportation efficiency. Moreover, it is easy to modify and is conducive to promotion and popularization.

[0041] The frame 12 can be configured as a cage structure, with the mortar tank 11 placed inside the frame and the insertion pipe 12a placed at the bottom of the frame 12.

[0042] Specifically, the push block 32 has a limiting part to limit its sliding position into the insertion tube 12a, so as to avoid the push block 32 affecting the insertion of the fork tooth 21 into the insertion tube 12a.

[0043] The push rod 31 is also provided with a limiting part to limit the extreme position of the push rod 31 sliding forward. The outer wall of the insertion tube 12a is fixedly connected to the sleeve. The push rod 31 is slidably connected to the sleeve. The limiting part on the push rod 31 limits the extreme position of the push rod 31 sliding forward by abutting against the rear end of the sleeve.

[0044] The mortar tank 11 can be made of stainless steel to balance cost and service life.

[0045] Example 2:

[0046] Reference Figures 1-3 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0047] The lower end of the mortar tank 11 forms a mortar inlet 11a. The mortar receiving device 1 also includes a conduit 13, a first valve 14, and a second valve. One end of the conduit 13 is connected to the mortar inlet 11a. The first valve 14 is located at the mortar inlet 11a to allow mortar to selectively enter the conduit 13. The second valve is located at the other end of the conduit 13 to allow mortar to selectively exit from the conduit 13.

[0048] In this embodiment, the bottom of the mortar tank 11 is provided with a mortar outlet 11a for discharging mortar, which serves as the main channel for mortar outflow. The mortar outlet 11a is fixedly connected to one end of the conduit 13 by a connecting structure such as a clamp, forming a continuous channel for conveying mortar from the inside of the tank to the outside.

[0049] The conduit 13 is designed to be flexible, serving as an intermediate channel for mortar transport, facilitating flexible pipe layout and control of mortar flow direction on the construction site. A first valve 14 is located at the connection between the mortar inlet 11a and the conduit 13, primarily used to control whether mortar flows from the mortar tank 11 into the conduit 13. When the first valve 14 is open, mortar enters the conduit 13 from the tank under gravity or pumping pressure; when it is closed, it cuts off the passage between the tank and the conduit 13, preventing mortar leakage or dripping and ensuring no mortar accumulation in the conduit 13 when not in use. A second valve is installed at the outlet of the other end of the conduit 13, used to control whether mortar is discharged from the conduit 13. By independently operating the second valve, the outlet can be temporarily closed even when the conduit 13 is filled with mortar, achieving a "pre-loaded and ready-to-go" operation mode and improving the controllability of the construction schedule.

[0050] The combined use of the two valves enables multi-level control of the mortar delivery process: for example, during transportation, both valves are closed to ensure that the mortar is completely sealed in the tank and prevent accidental leakage; upon arrival at the construction site, the first valve 14 can be opened first to allow the mortar to flow into the conduit 13, and after the conduit 13 is full, the second valve can be opened as needed to discharge the material; alternatively, the first valve 14 can be opened only while the second valve remains closed, depending on the site requirements, to pre-fill the conduit 13 for rapid response to subsequent construction.

[0051] The first valve 14 is configured as a gate switch, and the second valve is a flow switch.

[0052] The first valve 14 adopts a gate switch type, which has the characteristics of rapid opening and closing and large flow cross section, and can reliably control the flow of mortar from mortar tank 11 to conduit 13. The gate switch can be controlled by manual lever opening and closing.

[0053] The second valve is designed as a flow switch, which not only has on / off functions but also regulates the flow rate during mortar discharge. The flow switch can take the form of a regulating valve or a variable diameter ball valve. By rotating the handle to adjust the valve opening, the speed at which mortar flows out from the end of conduit 13 and the amount of mortar discharged per unit time can be precisely controlled. This allows operators to flexibly adjust the mortar output flow rate according to the specific needs of the construction site, avoiding waste or reduced construction quality due to excessively rapid discharge, or reduced work efficiency due to excessively slow discharge.

[0054] The two valves also support segmented maintenance and cleaning—for example, after construction is completed, the first valve 14 can be closed first, and then the conduit 13 and the second valve can be flushed to prevent cleaning water or cleaning medium from flowing back into the mortar tank 11 and to protect the quality of the remaining materials in the tank.

[0055] Example 3:

[0056] Reference Figures 1-3 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0057] The mortar storage device 1 also includes a lining layer laid on the inner wall of the mortar tank 11. The lining layer can be a polytetrafluoroethylene lining.

[0058] In this embodiment, the lining layer effectively improves the durability and performance of the tank.

[0059] The lining layer is directly bonded to the inner metal wall of the mortar tank 11, forming a physical barrier to reduce wear, corrosion, and adhesion of the mortar to the tank material during storage and flow. Considering the highly abrasive and alkaline properties of mortar, long-term use can easily lead to scratches, rust, or scale buildup on the inner wall of ordinary metal tanks, affecting tank lifespan and increasing cleaning difficulty. The introduction of the lining layer significantly alleviates this problem.

[0060] Preferably, the lining layer can be made of polytetrafluoroethylene (PTFE), which, due to its extremely low coefficient of surface friction and excellent chemical stability, effectively prevents mortar from adhering to the tank wall, making the mortar discharge process smoother, reducing residue, and improving the emptying rate. Simultaneously, PTFE has excellent corrosion resistance, resisting the alkaline components in cement-based materials and the chemical erosion of additives, extending the maintenance cycle and overall service life of the mortar tank 11. Furthermore, the material's smooth surface and non-adhesive nature facilitate cleaning after changing mortar types or prolonged periods of inactivity, reducing manual cleaning intensity and maintenance costs. The lining layer can be firmly installed on the inner wall of the tank through bonding, mechanical fixing, or other methods, ensuring that it does not warp, detach, or delaminate during frequent loading, unloading, and vibrating transportation.

[0061] Example 4:

[0062] Reference Figures 1-3 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0063] The front end of the push block 32 extending into the cannula 12a forms a guide surface 32b. During the insertion of the cannula 12a, the fork tooth 21 can squeeze the guide surface 32b, thereby causing the push block 32 to slide away from the cannula 12a.

[0064] In this embodiment, the guide surface 32b faces the insertion direction of the insertion tube 12a and has an inclined or rounded geometric shape, enabling it to contact the front end or side edge of the fork 2 tooth 21 as it enters the insertion tube 12a. When the fork 21 begins to insert into the insertion tube 12a, its forward path encounters the portion of the push block 32 that extends into the tube, and the end or side of the fork 21 first contacts the guide surface 32b at the front end of the push block 32. Due to the smooth inclined structure of the guide surface 32b, the fork 21 applies an inclined pressure to this surface under continuous pushing action. This force can be decomposed into a resistance along the movement direction of the fork 21 and a lateral component perpendicular to the movement direction. This lateral component pushes the push block 32 to slide outward along the groove on the side wall of the insertion tube 12a, thereby clearing a path for the smooth entry of the fork 21. This achieves the automatic avoidance function in the initial stage of fork 21 insertion, avoiding rigid collisions or jamming, and significantly improving the smoothness of docking and the operational error tolerance.

[0065] Example 5:

[0066] Reference Figures 1-3 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0067] The front end of the fork tooth 21 is tilted upward so that the mortar collection device 1 tends to slide towards the forklift 2 after being lifted by the fork tooth 21. This facilitates the push rod 31 to slide with the mortar collection device 1 to a position close to the forklift 2, so that the push rod 31 can reliably receive the clamping force from the forklift 2 and improve the reliability of the locking part 3.

[0068] Example 6:

[0069] Reference Figures 1-3 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0070] The push rod 31 can slide forward to the front limit position; at the front limit position, the first inclined part 31a corresponds to the outer position of the push block 32 to limit the push block 32 to slide outward to the limit position.

[0071] In this embodiment, in the previous extreme position state, the first inclined surface 31a on the push rod 31 corresponds to the area where the second inclined surface 32a is located on the outside of the push block 32, forming a spatial blocking and limiting relationship, physically preventing the push block 32 from sliding further outward. At this time, even if the fork tooth 21 applies a pushing force through the guide surface 32b during insertion, the outward movement of the push block 32 will be constrained by the structure of the first inclined surface 31a, and it cannot continue to move away from the center of the insertion tube 12a, thereby setting the maximum limit position for the push block 32 to slide outward, and preventing the push block 32 from dislodging from the insertion tube 12a.

[0072] Example 7:

[0073] Reference Figures 1-3 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0074] The locking element 3 also includes an elastic element 33; the elastic element 33 is adapted to retain a spring force that applies forward sliding to the push rod 31; and / or; the elastic element 33 is adapted to retain a spring force that applies outward sliding to the push block 32.

[0075] In this embodiment, the entire locking mechanism has an automatic reset function through elastic force. The elastic element 33 can be in the form of a compression spring or a rubber elastomer, and its arrangement can be flexibly set according to actual structural requirements. By setting the elastic element 33, manual intervention is reduced, and the automation capability and operating efficiency of the equipment are improved.

[0076] For example, the elastic element 33 can act on the push rod 31, so that it is always subjected to a forward sliding elastic force, ensuring that the push rod 31 automatically returns to the front limit position when no external force is applied.

[0077] Example 8:

[0078] Reference Figures 1-3 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0079] The frame 12 is also equipped with lifting lugs, which can be used to lift the mortar storage device 1.

[0080] In this embodiment, the lifting lugs can be made of high-strength metal materials, such as forged steel or thick plate welded parts, with sufficient load-bearing capacity and safety margin, capable of bearing the weight of the entire mortar storage device 1 in an unloaded or fully loaded state.

[0081] Lifting lugs can be symmetrically arranged on both sides or the top of the frame 12 to ensure even force distribution during lifting and avoid the risk of tilting, swaying, or even overturning of the device due to uneven loading. When lifting equipment is required for handling or hoisting operations, lifting tools such as wire ropes, slings, or hooks of electric hoists can be directly connected to the lifting lugs to form a reliable lifting fulcrum.

[0082] The mortar storage device 1 can not only be horizontally transported by forklift 2, but also adapted to lifting equipment. On the one hand, after the mortar is transported to the designated location by the mortar transportation system in the prefabricated building plant, the mortar storage device 1 can be lifted and supported by the lifting equipment, thus facilitating the detachment of the forklift 2 from the mortar storage device 1. On the other hand, the lifting equipment can also give the mortar storage device 1 a certain height, thereby giving the mortar outlet 11a at the bottom of the mortar tank 11 a certain height as well, making the mortar output position more flexible, and also facilitating the use of the height difference between the output end of the conduit 13 and the mortar tank 11 to improve the mortar output efficiency.
