Description

Technical Field

[0001] This invention relates to the field of air-supported membrane structure construction technology, and specifically to a material transport device for air-supported membrane structure construction. Background Technology

[0002] With its advantages such as beam-free large-span space, modular rapid construction, and low operation and maintenance costs, air-supported membrane structures have become the preferred solution to replace traditional buildings and solve problems such as long construction periods and limited space. They are often used in large-scale warehousing and logistics centers, industrial plants, and environmentally friendly enclosed facilities.

[0003] The construction process of an air-supported membrane structure requires the sequential completion of key steps such as precise pouring of the concrete foundation, hoisting and fixing of the air-supported membrane units, layered spraying of rigid polyurethane foam, and binding of the reinforcing steel structure. This places stringent requirements on the adaptability of the material transport devices to various forms, connection stability, material protection, and scenario compatibility. The materials used in the construction of the air-supported membrane structure include polyurethane spray, air-supported membrane hoisting accessories, and reinforcing steel, among others. These materials present various transportation challenges. Polyurethane spray is temperature-sensitive; temperature runaway during transportation can affect the layered bonding effect. Air-supported membrane hoisting accessories lack cushioning protection and are easily damaged by collisions. Reinforcing steel requires considerable storage space.

[0004] Traditional material handling equipment is mostly of general-purpose structure. When transporting materials of different shapes, such as steel bars, polyurethane spray and air-supported membrane hoisting accessories, multiple specific material handling equipment are required for specific transportation. During construction, it is necessary to frequently change material handling equipment to transport different materials, resulting in low efficiency in process connection. Summary of the Invention

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, so as to provide a better understanding of the concept of the present invention, the technical problem solved, the technical features constituting the technical solution, and the technical effects brought about.

[0025] like Figures 1-3 As shown, a material transport device for the construction of an air-supported membrane structure includes a movable frame 1, a support platform 4 on top of the movable frame 1, and the support platform 4 connected to the movable frame 1 via a lifting assembly; it also includes a first placement platform 71, a second placement platform 74, and a third placement platform 78, which are interchangeably mounted on the support platform 4; the first placement platform 71 is used to place reinforcing bars, the second placement platform 74 is provided with an insulation structure for placing polyurethane spray, and the third placement platform 78 is provided with a buffer structure for placing air-supported membrane hoisting accessories.

[0026] This invention provides a material transport device for the construction of an air-supported membrane structure, including a movable frame 1. The movable frame 1 is capable of movement and can lift and lower the support platform 4 through a lifting component. It works in conjunction with a first placement platform 71, a second placement platform 74, or a third placement platform 78 to specifically load steel bars, polyurethane spray, and air-supported membrane hoisting accessories, thereby achieving efficient material transport in the construction environment of the air-supported membrane structure.

[0027] Furthermore, the first placement platform 71 is provided with one or more arc-shaped first receiving grooves 713, which connect the front end and the rear end of the first placement platform 71. The reinforcing bars are strip-shaped materials, and placing the reinforcing bars in the arc-shaped receiving grooves facilitates transportation and storage. The first receiving grooves 713 connect the front end and the rear end of the first placement platform 71, so that the first receiving grooves 713 can hold reinforcing bars that are longer than the first placement platform 71.

[0028] Furthermore, the first placement platform 71 is provided with a sliding groove 72, and a slidable extension bracket 73 is provided in the sliding groove 72. An electric push rod is also installed in the sliding groove 72. The piston end of the electric push rod is connected to the extension bracket 73. The electric push rod controls the extension bracket 73 to extend and retract, thereby extending the placement length of the first receiving groove 713.

[0029] like Figure 4As shown, further, the second placement platform 74 is provided with one or more placement grooves 76. The protective structure is a cylindrical heating and insulation strip 75, which is placed in the placement groove 76. The heating and insulation strip 75 includes, from the inside out, an electric heating layer 751, a rock wool layer 752, and an aluminum foil protective layer 753. The heating and insulation strip 75 is also equipped with a temperature sensor and a heating element 754. The heating element 754 can be any commonly used electric heating device. The heating element 754 is installed on the electric heating layer 751 to heat the heating and insulation strip 75. The rock wool layer 752 serves to insulate and reduce energy loss. The aluminum foil protective layer 753 reflects energy, reduces heat leakage, and prevents the heating effect from being affected and prevents the heating and insulation strip 75 from being affected by temperature rise. The temperature sensor detects the internal temperature of the heating and insulation strip 75 and provides feedback to the operator. The operator controls the heating element 754 based on the temperature sensor data to ensure that the temperature range of the heating and insulation strip 75 is within the suitable storage temperature range for the polyurethane spray.

[0030] Furthermore, multiple elastic tube clamps 77 are installed on the edge of the placement groove 76. The elastic tube clamps 77 are used to clamp the heating and insulation strip 75 inside the placement groove 76. The multiple elastic tube clamps 77 are equally spaced on the edge of the placement groove 76, and together they clamp the heating and insulation strip 75 inward to prevent the heating and insulation strip 75 from falling off during transportation.

[0031] Furthermore, the third placement platform 78 is provided with a rectangular second receiving groove 79, and the buffer structure is a flexible buffer pad 710, which is installed on the bottom and side walls of the second receiving groove 79. The top of the third placement platform 78 is provided with multiple partition slots 711, through which partition plates 712 are engaged, dividing the second receiving groove 79 into multiple placement areas. The bottom of the partition plates 712 is made of silicone. The flexible buffer pad 710 is a general term for a type of material, which can be rubber pads, polyurethane pads, foam pads, etc. The silicone used at the bottom of the partition plates 712 serves the same purpose as the flexible buffer pad 710: to reduce the impact of air-supported lifting accessories during transportation.

[0032] like Figure 5As shown, the support platform 4 is further equipped with guide pins 51 and pneumatic latches 5. The first placement platform 71, the second placement platform 74, and the third placement platform 78 are respectively provided with corresponding insertion holes 8. The pneumatic latches 5 control the guide pins 51 to complete vertical extension and retraction, and complete the engagement of the guide pins 51 with the insertion holes 8. The first placement platform 71, the second placement platform 74, and the third placement platform 78 are installed on the support platform 4 in a replaceable manner. After replacement, they are fixed by using guide pins 51 and insertion holes 8. The vertical guide pins 51 and insertion holes 8 can prevent the first placement platform 71, the second placement platform 74, and the third placement platform 78 from moving horizontally. Since the first placement platform 71, the second placement platform 74, and the third placement platform 78 have a certain weight, it is difficult for them to fall off vertically.

[0033] Furthermore, a pressure sensor is installed inside the pneumatic latch 5, and a control compartment 2 is installed on the movable frame 1. The control compartment 2 is electrically connected to the pressure sensor. The pressure sensor monitors the locking pressure of the pneumatic latch 5 in real time and feeds it back to the controller to prevent the first placement platform 71, the second placement platform 74, and the third placement platform 78 from loosening or falling off. Preferably, the top of the guide pin 51 is provided with a tapered guide head for quick alignment of the insertion hole 8.

[0034] Furthermore, outer frames 6 are respectively installed on the left and right sides of the support platform 4. The outer frames 6 are used to restrict the first placement platform 71, the second placement platform 74, and the third placement platform 78. Multiple binding straps 9 are also included, with one end of each binding strap 9 fixedly connected to one of the outer frames 6, and the other end fastened to the other outer frame 6, thus securing the first placement platform 71, the second placement platform 74, and the third placement platform 78. The binding straps 9 are adjustable in length and can be adapted to different sized placement units, such as elastic bands or straps with a telescopic structure.

[0035] Furthermore, the lifting assembly is a scissor lift 3.

[0036] The overall usage process of this invention is as follows: 1. Use a forklift to lift the first placement platform 71 to the top of the support platform 4. Align it during the lifting and placement process. The outer frames 6 on the left and right sides of the support platform 4 have an auxiliary alignment function. Under the manual control of the forklift, make the insertion hole 8 of the first placement platform 71 align with the support platform 4. Then control the pneumatic lock 5 to complete the engagement of the guide pin 51 and the insertion hole 8. The pressure sensor transmits pressure data.

[0037] Based on the length of the reinforcing bar to be transported, control whether the extension bracket 73 is extended and by how much. Wait for the extension bracket 73 to slide to the designated position, place the reinforcing bar in the first receiving groove 713, and fasten and tighten the binding strap 9 on the outer frame 6 to prevent the reinforcing bar from slipping.

[0038] 2. Use a forklift to replace the first placement platform 71 with the second placement platform 74, control the heating element 754 to heat the electric heating layer 751, the rock wool layer 752 for insulation, and the aluminum foil protective layer 753 to reflect heat; the temperature sensor provides real-time temperature feedback.

[0039] Fill the storage tank with polyurethane spray, place the storage tank into the placement groove 76 of the second placement platform 74, adjust the elastic pipe clamp 77 to wrap around the outer wall of the storage tank, and manually tighten the pipe clamp knob until the storage tank has no radial shaking; check the length of the connecting pipe between the storage tank outlet and the spray pump to ensure that the pipe is not pulled when the support platform 4 is raised and lowered.

[0040] 3. Use a forklift to replace the second placement platform 74 with the third placement platform 78. After positioning and locking by the guide pin 51, the pressure sensor confirms that the pressure is qualified. The air membrane accessories include membrane clamps, anchor bolts, and sealing strips. The silicone bottom of the partition plate 712 is attached to the flexible buffer pad 710 to form an independent partition. Insert the partition plate 712 into the partition slot 711 of the rectangular container. Classify and place the accessories into the partitions, ensuring that there is no gap between the accessories and the partition plate 712 to avoid shaking during transportation. Wrap the top of the rectangular container with the binding strap 9 and tighten the strap until the accessories do not jump up and down.

[0041] 4. After construction is completed, unload the remaining materials and clean the first placement platform 71, the second placement platform 74, and the third placement platform 78. Lower the scissor lift 3 to its lowest position and drive the movable frame 1 back to the equipment storage area; turn off the power to the control compartment 2, check that all components are undamaged, and then cover them with dust covers.
