DETAILED DESCRIPTION
[0029] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.
[0030] like Figures 1 to 4 As shown, an introduction roller for a tenon standard section includes:
[0031] The roller frame 1 is provided with a positioning pin 11 and a bayonet 12. The positioning pin 11 can be inserted into the mortise of the main chord rod 61 of the tenon standard section 6, and the bayonet 12 can be clamped with the web rod 62 of the tenon standard section 6;
[0032] The rotating shaft 2 is fixed on the roller frame 1 and extends outward from the roller frame 1;
[0033] The roller 3 is sleeved on the rotating shaft 2 and is located outside the roller frame 1 .
[0034] In this application, the introduced roller is clamped at the bottom of the tenon standard section 6 to support and enable the tenon standard section 6 to move in a preset direction. Among them, the positioning pin 11 and the mortise of the main chord 61 form a connection point through shaft-hole fit; the bayonet 12 and the web member 62 form another connection point through shape fit; the two connection points fix the relative position of the introduced roller and the tenon standard section 6 and transmit the gravity of the tenon standard section 6. The roller 3 rotates freely on the rotating shaft 2 to enable the tenon standard section 6 to move in a preset direction. When installing the introduced roller, along the axial direction of the mortise of the main chord 61, insert the positioning pin 11 into the mortise of the main chord 61, and at the same time clamp the bayonet 12 to the web member 62 to complete the installation; when disassembling the introduced roller, pull it out in the opposite direction.
[0035] Specifically, the insertion direction of the positioning pin 11, the clamping direction of the bayonet 12, and the extending direction of the rotating shaft 2 are all the same.
[0036] Specifically, the roller frame 1 includes an upper plate 13, a lower plate 14, and a side plate 15 that form a "C" - shaped structure. One end of the side plate 15 is provided with a positioning pin 11, and a bayonet 12 is formed above the lower plate 14. The lower plate 14 can support the web member 62 of the tenon standard section 6.
[0037] Furthermore, the roller frame 1 further includes a reinforcing plate 16 located between the upper plate 13 and the lower plate 14. The reinforcing plate 16 is connected to the upper plate 13, the lower plate 14, and the side plate 15. The reinforcing plate 16 is used to enhance the connection strength between the upper plate 13, the lower plate 14, and the side plate 15 and improve the overall stability of the roller frame 1.
[0038] Furthermore, the reinforcing plate 16 is a "Z" - shaped plate placed in a rotating manner, and the gap between the reinforcing plate 16 and the lower plate 14 forms the bayonet 12. By optimizing the shape of the reinforcing plate 16 so that it combines with the lower plate 14 to form the bayonet 12, the processing procedure of the bayonet 12 on the roller frame 1 is reduced, and the production cost is lowered.
[0039] Furthermore, the roller frame 1 further includes a reinforcing sleeve 17 located on the side plate 15. The reinforcing sleeve 17 is used to extend the support of the side plate 15 to the rotating shaft 2. When the rotating shaft 2 passes through the through - hole on the side plate 15 and is fixed to the side plate 15, the reinforcing sleeve 17 at the through - hole forms an additional support for the rotating shaft 2, strengthening the support strength of the side plate 15 to the rotating shaft 2.
[0040] Furthermore, the roller frame 1 further includes a handle 18 located on the surface of the upper plate 13. The handle 18 is used to lift and carry the introduced roller, facilitating the installation of the introduced roller.
[0041] In some embodiments, the roller frame 1 is welded by an upper plate 13, a lower plate 14, a side plate 15 and a reinforcing plate 16. The upper plate 13 and the lower plate 14 are "L"-shaped plates to reduce the probability of interference with other structures on the main chord 61 of the tenon standard section 6. The side plate 15 and the reinforcing plate 16 are both located between the upper plate 13 and the lower plate 14. The side plate 15 is welded to the vertical side of the "L" shape, and the reinforcing plate 16 is welded to the horizontal side of the "L" shape. The two reinforcing plates 16 are arranged at a certain distance, and the three surfaces of the reinforcing plate 16 are respectively welded to the upper plate 13, the lower plate 14 and the side plate 15. The size of the positioning pin 11 is adapted to the mortise of the main chord 61 of the tenon standard section 6. The positioning pin 11 is perpendicular to the side plate 15 and is fixed to one end of the side plate 15 by welding or fastening. The shape of the bayonet 12 is adapted to the web 62 of the tenon standard section 6. The bayonet 12 is formed by combining the edge of the reinforcing plate 16 and the upper surface of the lower plate 14. The other end of the side plate 15 is provided with a through hole for passing the rotating shaft 2, and a reinforcing sleeve 17 is welded to one side of the through hole. The handle 18 is in a “∩” shape and is welded to the upper surface of the upper plate 13.
[0042] Specifically, the introduction roller also includes a latch 4, which is sequentially plugged into the upper plate 13, the lower plate 14 and the web 62 of the tenon standard section 6, and the latch 4 is used to limit the relative position of the introduction roller and the tenon standard section 6.
[0043] Specifically, the introduction roller further comprises a chain 5, one end of the chain 5 is connected to the roller frame 1, and the other end is connected to the latch 4. The chain 5 is used to prevent the latch 4 from being lost or falling off.
[0044] In some embodiments, one end of the rotating shaft 2 passes through the side plate 15 and the reinforcing sleeve 17 of the roller frame 1 and extends outward from the roller frame 1. The roller 3 has a flange on one side and is mounted on the rotating shaft 2 through a bearing. Its axial position is adjusted by a sleeve sleeved on the rotating shaft 2, and the axial fastening is completed by a fastener on the end surface of the rotating shaft 2. The latch 4 can be inserted into the pin holes on the upper plate 13, the lower plate 14 and the web 62 of the tenon standard section 6 of the roller frame 1. One end of the chain 5 is connected to the handle 18 of the roller frame 1 through a spring hook, and the other end is connected to the end of the latch 4.
[0045] like Figure 1 , Figure 5 As shown, in some embodiments, the introduction roller is used as follows:
[0046] The handle 18 of the hand-held introduction roller is positioned, and the bayonet 12 of the introduction roller is clamped on the web 62 at the lower end of the tenon standard section 6 from the outside of the tenon standard section 6, and the positioning pin 11 of the introduction roller is inserted into the mortise of the main chord 61 of the tenon standard section 6, as shown in FIG. Figure 5 Finally, the pin 4 of the introduction roller is inserted into the pin holes on the upper plate 13, the lower plate 14 and the web 62 of the tenon standard section 6 of the roller frame 1 in sequence to prevent the introduction roller from sliding or falling.
[0047] A climbing device for a tenon standard section includes an introduction platform and the above-mentioned introduction roller, wherein a roller frame 1 is clamped at the bottom of the tenon standard section 6, and a roller 3 is located outside the tenon standard section 6 and can roll on the introduction platform.
[0048] In some embodiments, the climbing device is installed outside the tower body. The tenon standard section 6 is hoisted from the ground and placed on the introduction platform of the climbing device. Figure 6 As shown, each main chord 61 of the tenon standard section 6 is clamped with an introduction roller, and there are 4 introduction rollers in total. After the introduction rollers are installed, the tenon standard section 6 moves as a whole on the introduction platform through the rolling of the rollers 3 and is introduced into the center of the tower body.
