[0033] The PC wall panel transport rack type of the present invention includes a connecting piece, at least two support frames 1 and at least four positioning pieces 2; the support frame 1 includes a frame body 101 with an isosceles trapezoid cross-section and a support bar 103, and wedge-shaped blocks 102 for obliquely supporting the wall panel are respectively arranged on both sides of the support bar 103. Both ends of the connecting piece are respectively connected to the two frame bodies 101. The positioning piece 2 includes a positioning plate 201 and a threaded rod 202 threadedly connected to the positioning plate 201. Extension plates 3 are detachably and parallelly connected to both sides of each support bar 103. The four positioning plates 201 correspond to the four extension plates 3 one by one, and the positioning plate 201 is detachably and vertically connected to the corresponding extension plate 3;

[0034] In the transportation state, the wall panel is located above the wedge-shaped block 102 and on both sides of the frame body 101. The four threaded rods 202 are clamped in pairs on both sides of the truck bed.

[0035] The PC wallboard transport rack of the present invention is provided with a connecting member, at least two support frames 1 and at least four positioning members 2. The connecting member connects the two support frames 1 to fix the overall frame of the transport rack. The support frame 1 includes a frame body 101 with an isosceles trapezoid cross-section and a support bar 103. The wedge-shaped blocks 102 on both sides of the support bar 103 are used to provide inclined support for the bottom of the PC wallboard when the PC wallboard is placed on the transport rack. The positioning member 2 includes a positioning plate 201 and a threaded rod 202. The positioning plate 201 provides a connection point through an extension plate 3 and is detachably connected to both sides of the support bar 103, enabling the positioning member 2 to be installed when the transport rack is on the vehicle board. When the transport rack is on the vehicle board, the two positioning plates 201 on each support bar 103 are respectively clamped on both sides of the vehicle board, and the threaded rods 202 on the two positioning plates 201 on the same support bar 103 can generate displacement through threaded connection to clamp the vehicle board, thereby achieving the fixing effect of the transport rack on the vehicle board, stably positioning the transport rack, and preventing the risk of overturning of the storage rack during transportation. And in the present invention, the detachable connection between the extension plate 3 and the support bar 103 and the detachable connection between the extension plate 3 and the positioning plate 201 adopt a bolt connection method. When the PC wallboard is transported, one PC wallboard is inclinedly supported on each side of the support frame 1. The side of the PC wallboard contacts the side surface of the frame body 101, and the bottom of the PC wallboard contacts the wedge-shaped block 102.

[0036] In an embodiment, at least one waist-shaped hole 301 is formed on the side of the extension plate 3 away from the corresponding support bar 103. The waist-shaped hole 301 is used to adjust the lateral distance between the corresponding positioning plate 201 and the vehicle board, and the corresponding positioning plate 201 is detachably connected to the extension plate 3 through a bolt passing through the waist-shaped hole 301. With this design, the distance between the two positioning members 2 installed on the same support bar 103 can be extended through the setting of the waist-shaped hole 301 to meet the clamping and fixing of vehicle boards with different widths.

[0037] In one embodiment, the connecting member is a scissor-type telescopic frame 4. The scissor-type telescopic frame 4 includes two symmetrically arranged diamond-shaped telescopic frames 401 and a plurality of connecting rods 402 for connecting the corresponding hinge points of the two diamond-shaped telescopic frames 401. Among the two connecting rods 402 at the ends of the two diamond-shaped telescopic frames 401, one is fixedly connected to the corresponding frame body 101, and the other is slidably connected to the corresponding frame body 101 in the vertical direction. With this design, the distance between the two support frames 1 can be adjusted through the scissor-type telescopic frame 4, and the length of the entire transport frame can be adjusted, which can be applicable to PC wallboards of different lengths or truck decks of different lengths. And in this embodiment, the number of support frames 1 is an even multiple, and the distance between adjacent two support frames 1 can be adjusted through the scissor-type telescopic frame 4. And by extending the length of the transport frame as much as possible through the scissor-type telescopic frame 4 and cooperating with the wedge blocks 102 on the plurality of support bars 103, it is possible to support more than two PC wallboards on one side of the transport frame at the same time.

[0038] In one embodiment, the connecting rod 402 slidably connected to the frame body 101 includes an operation block 4021, two sleeves 4022, two extension rods 4023 and two threaded columns 4024. Sliding grooves 1011 for the corresponding connecting rods 402 to slide are respectively formed on both sides inside the frame body 101. The operation block 4021 is arranged between the two sleeves 4022 and is rotatably connected to one end of the two sleeves 4022. The other ends of the two sleeves 4022 are respectively slidably connected to the two sliding grooves 1011. The two threaded columns 4024 are respectively arranged horizontally in the two sleeves 4022. The inner parts of the two extension rods 4023 are respectively threadedly connected to the two threaded columns 4024, and the outer parts are respectively slidably connected to the two sleeves 4022 in the length direction. With this design, by rotating the operation block 4021, the threaded column 4024 rotates. Since the extension rod 4023 is threadedly connected to the threaded column 4024 and is slidably connected to the sleeve 4022, the extension rod 4023 can be extended or retracted into the sleeve 4022. That is, after the diamond-shaped telescopic frame 401 is extended or retracted to a specified position, by rotating the operation block 4021, the two extension rods 4023 are rotated out of the sleeve 4022 and abutted against the groove wall of the sliding groove 1011, and the fixing effect on the diamond-shaped telescopic frame 401 can be achieved. The operation is simple and convenient. And in this embodiment, the threads on the two threaded columns 4024 are symmetric.

[0039] In one embodiment, a sleeve 4025 is further provided at one end of each of the extension rods 4023 away from the operation block 4021. A fixing block 4026 is slidably sleeved on the outer side of the sleeve 4025 along the length direction, and a spring 4027 is provided between the fixing block 4026 and the sleeve 4025. With such a design, when the two extension rods 4023 are rotated out of the sleeve 4022, the fixing block 4026 abuts against the groove wall of the chute 1011, and the elastic force of the spring 4027 enhances the fixing effect of the abutment. Moreover, the sleeve 4025 can limit the spring 4027 when the spring 4027 is compressed to prevent the spring 4027 from bending.

[0040] In one embodiment, a reinforcing rod 5 is further included. The reinforcing rod 5 includes a fixed section 501 and two extension sections 502 detachably provided at both ends of the fixed section 501. The two extension sections 502 can be detachably connected to the two support bars 103 respectively. With such a design, the support bars 103 of the two support frames 1 are connected by the reinforcing rod 5 to enhance the stability of the support frame 1. Moreover, in this embodiment, the provided extension section 502 and the fixed section 501 are made of U-shaped steel structures, and the extension section 502 can be slidably arranged inside the fixed section 501. The fixed section 501 and the extension section 502 are detachably connected by bolts, and the connection position of the reinforcing rod 5 is set on the principle of not blocking the inclined setting of the PC wall panel.

[0041] In one embodiment, the reinforcing rod 5 further includes an auxiliary wedge-shaped support block 503 provided on the fixed section 501. When the two extension sections 502 are fixed to the two support bars 103, the upper surface of the auxiliary wedge-shaped support block 503 is in the same plane as the upper surface of the wedge-shaped block 102. With such a design, after connecting the reinforcing rod 5, the auxiliary wedge-shaped support block 503 on the reinforcing rod 5 becomes the bottom support point of the PC wall panel between the two support frames 1, improving the stability of the support for the PC wall panel. Moreover, in this embodiment, the provided reinforcing rod 5 is embedded in the support bar 103 and detachably connected by bolts, ensuring that the reinforcing rod 5 does not block the inclined setting of the PC wall panel and also ensuring that the upper surface of the auxiliary wedge-shaped support block 503 is in the same plane as the upper surface of the wedge-shaped block 102.

[0042] In one embodiment, rubber layers 6 are provided on the side surface of the frame body 101, the wedge-shaped block 102, and the upper surface of the auxiliary wedge-shaped support block 503. With such a design, it is prevented that the contact surface of the wall panel is damaged when handling the PC wall panel.

[0043] In one embodiment, it further includes a top plate 7, and the top plate 7 is detachably connected to the tops of the two frame bodies 101. With such a design, when fixing the PC wallboard, workers can work on the top plate 7. And in this embodiment, the provided top plate 7 is made of steel plate and is detachably connected to the top of the support frame 1 by bolts. Moreover, there are multiple top plates 7, and the lengths of the multiple top plates 7 are all different, which is used to conform to the characteristic that the length of the transport rack is adjustable.

[0044] In one embodiment, it further includes a ladder 8 arranged on the side of one of the frame bodies 101 and a handrail 9 for assisting the ladder 8. With such a design, it is convenient for construction workers to climb to the top of the support frame 1 to install the top plate 7 and to step onto the top plate 7 after the top plate 7 is installed. And in this embodiment, there are two handrails 9, which are respectively located on both sides of the side of the frame body 101.

[0045] In one embodiment, receiving grooves 1031 are respectively formed on both sides of the bottom of the support bar 103. A support plate 1032 is arranged in the receiving groove 1031. A lead screw 1033 is threadedly connected to the support plate 1032. A pulley 1034 is rotatably arranged at the bottom of the lead screw 1033, and the pulley 1034 can enter and exit the receiving groove 1031. With such a design, the extension degree of the scissor-type telescopic frame 4 can be conveniently adjusted through the pulley 1034. When adjusting, the pulley 1034 is turned out of the receiving groove 1031, and after adjustment, the pulley 1034 is retracted by rotating the lead screw 1033. The operation is convenient, time-saving and labor-saving.

[0046] In the present invention, during the specific use process, first adjust the extension length of the scissor-type telescopic frame 4 according to the vehicle length, then fix the scissor-type telescopic frame 4, and then fix the reinforcing rod 5 on the support bar 103 of the support frame 1, fix the top plate 7 on the top of the support frame 1, install the positioning member 2 on the support bar 103 and clamp and fix the vehicle plate. The above process is carried out on the vehicle plate, and then the PC wallboard is hoisted and placed obliquely on both sides of the transport rack, and the precast wallboard is fixed to the transport vehicle through straps.
