[0032] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0033] like Figure 1 As shown, the present invention provides a device for vertically laying flexible materials, which includes two identical components. The two components are arranged opposite to each other, and only by being arranged opposite to each other can the flexible material be fixed in the middle.

[0034] Each component includes: a support plate 6, a support rod 3, a roller 7, an inflatable cushion 5, a chain 4, a transmission shaft 8 and a drive shaft 2. The support rod 3 is vertically fixed on the same surface of the support plate 6, and the support rod 3 is divided into two rows, and is in a position parallel to each other. A transmission shaft 8 is fixed between the two parallel support rods 3, and a roller 7 is fixed on each transmission shaft 8. A roller 7 is also fixed on the drive shaft 2, and the positions of all rollers 7 are on the same plane, so that the flexible material 1 can be laid flatly. The chain 4 connects all rollers 7, and the inflatable cushion 5 fits all rollers 7. When the device is laying the flexible material 1, a support plate 6 on one side of the device is fixed to the upper part of the inner wall of the groove. The rotation of the drive shaft 2 drives the roller 7 fixed thereon to rotate, and then drives the roller 7 on the drive shaft 8 to rotate through the chain 4. When the roller 7 rotates, the inflated inflatable cushion 5 rotates with the roller 7, thereby driving the flexible material 1 to be laid vertically.

[0035] The sizes of the support rod 3, the transmission shaft 8 and the roller 7 in the device are the same, so that the rotation speed of the transmission shaft 8 can be better controlled to remain consistent, ensuring that the linear speed of the surface of the inflatable cushion 5 remains consistent when the chain 4 is driven.

[0036] like Figure 2 As shown, the present invention provides a flexible material vertical laying device. When laying the flexible material, the devices are symmetrically fixed in pairs on the upper part of the inner wall of the groove through a suspension device; a counterweight is fixed at the starting end of the flexible material 1, and then the starting end of the flexible material 1 is placed in the middle of the inflatable cushion 5 of the device; after the device is aligned, the inflatable cushion 5 is inflated, and the inflatable cushions 5 on both sides fix the flexible material 1 in the middle by squeezing; an external driving device 9 drives the driving shaft 2 to rotate, and the rotation of the driving shaft 2 drives the roller 7 fixed thereon to rotate, and then drives the roller 7 on the transmission shaft 8 to rotate through the chain 4. When the roller 7 rotates, the inflated inflatable cushion 5 rotates with the roller 7, thereby driving the flexible material 1 to be laid vertically; when the laying reaches the specified depth, the inflatable cushion 5 is deflated, and the device is withdrawn from the groove; the flexible material 1 is split at the position of the upper edge of the groove, the flexible material 1 is stretched to fit it with the groove wall, and finally the end of the flexible material 1 is fixed to the upper edge of the groove.

[0037] Embodiment 1: Flexible material vertical laying device

[0038] The device comprises two identical parts which are arranged facing each other.

[0039] Each component includes: a support plate 6, a support rod 3, a roller 7, an inflatable cushion 5, a chain 4, a transmission shaft 8 and a drive shaft 2. The sizes and models of the support plate 6, the support rod 3, the roller 7, the inflatable cushion 5, the chain 4, the transmission shaft 8 and the drive shaft 2 in all components are consistent.

[0040] The details of each component are as follows: the support plate 6 is a rectangular steel plate, which is 2m long, 1m wide and 3cm thick; support rods 3 are welded on the long sides of the steel plate, starting from the edge of the long side of the steel plate, and then a support rod 3 is welded every 0.5m, and 5 support rods 3 are welded on one long side of the steel plate; the support rods 3 are welded on the same surface of the steel plate through the ends, and the support rods 3 are 0.2m long; a transmission shaft 8 is set at a position parallel to the wide side of the steel plate, and the two ends of the transmission shaft 8 are respectively fixed to the other ends of the two parallel support rods 3. A total of 5 transmission shafts 8 are set, and these 5 transmission shafts 8 are in the same plane. Each transmission shaft 8 is covered with a roller 7, and the transmission shaft 8 has a protrusion The inner surface of the roller 7 has a recessed portion engaged with the raised portion on the transmission shaft 8. A circle of partitions is fixed on the outer circumference of the roller 7 to separate the chain 4 and the inflatable cushion 5 connected to the roller 7, and the thickness of the chain 4 is less than the thickness of the inflatable cushion 5; hooks are arranged at both ends of the driving shaft 2 to facilitate connection with the suspension equipment, and a roller 7 is also sleeved on the driving shaft 2, with a raised portion on the driving shaft 2, and a recessed portion engaged with the raised portion on the inner surface of the roller 7; the chain 4 is meshed with the raised portion on the outer surface of the roller 7 to connect all the rollers 7; the inflatable cushion 5 is in contact with all the rollers 7, and the raised portion on the outer surface of the roller 7 can drive the inflatable cushion 5 to rotate through friction.

[0041] When the laying device is working, the two ends of the driving shaft 2 of the two components are suspended by the suspension device, so that the chain 4 is tightly connected to the roller 7, and the inflatable cushion 5 is tightly fitted to the roller 7.

[0042] Embodiment 2: Vertical laying of flexible materials

[0043] The devices are fixed symmetrically in pairs on the upper part of the inner wall of the groove by the suspension equipment; the position of the device is appropriately adjusted according to the width of the flexible material 1, and the steel plate on one side of the device is tightly fitted to the inner wall of the groove; the counterweight is fixed at the beginning of the flexible material 1, and then the beginning of the flexible material 1 is placed in the middle of the inflatable cushion 5 of the device; after the device is aligned, the inflatable cushion 5 is inflated, and the inflatable cushions 5 on both sides are fixed in the middle by squeezing the flexible material 1, and the inflation of the inflatable cushion 5 is stopped when the flexible material 1 is fixed to the point where it will not be driven down by the counterweight; the external drive device 9 drives the drive shaft 2 The driving shaft 2 drives the roller 7 to rotate, and the roller 7 drives all the rollers 7 to rotate through the chain 4. When the roller 7 rotates, the inflatable cushion 5 rotates with the roller 7, thereby driving the flexible material 1 to be laid vertically. The rotation speed of the driving shaft 2 remains consistent, and the linear speed of the surface of the inflatable cushion 5 remains consistent during the transmission of the chain 4. After laying to the specified depth, the inflatable cushion 5 is deflated and the device is withdrawn from the groove. The flexible material 1 is divided at the upper edge of the groove, and the flexible material 1 is stretched to fit it with the groove wall, and finally the end of the flexible material 1 is fixed to the upper edge of the groove.

[0044] in conclusion:

[0045] During the vertical laying of the flexible material, the inflatable cushion can prevent the flexible material from being damaged during the laying process, and the support plate can prevent the groove wall from collapsing and damaging the flexible material.
