DETAILED DESCRIPTION

[0021] Here, it should be noted that the functions and methods involved in the present invention are merely conventional adaptive applications of the prior art. Therefore, the improvement of the present invention on the prior art is essentially the connection relationship between the hardware, rather than the functions and methods themselves. That is, although the present invention involves some functions and methods, it does not include improvements to the functions and methods themselves. The description of the functions and methods in the present invention is to better illustrate the present invention so as to better understand the present invention.

[0022] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0023] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0024] like Figure 1 and Figure 2 As shown, this embodiment provides a belt rigging installation structure, including a pulley body 1 and a belt rigging 2 connected to the pulley body 1 (the hook part of the belt rigging is not shown).

[0025] The pulley body 1 has a pulley section 11 for winding the belt rigging 2, and a slot 111 is provided on the outer circumference of the pulley section 11 along its axial direction, and one side of the slot 111 penetrates the outer circumference of the pulley section 11 to form a lead-out port 112, and the lead-out port 112 is arranged along the axial direction of the pulley section 11. Further, the slot 111 is sequentially designed as a clamping portion 1111 and a rounded corner portion 1112 in a direction away from the lead-out port 112, wherein the width of the clamping portion 1111 gradually increases in a direction away from the lead-out port 112, and the rounded corner portion 1112 is smoothly transitionally connected to one side of the clamping portion 1111 away from the lead-out port 112.

[0026] The end of the belt sling 2 forms a clamping end 21, in which a latch 211 is arranged. The latch 211 is made of metal. The clamping end 21 is plugged into the slot 111, and the maximum width of the clamping end 21 is greater than the width of the outlet 112. Specifically, the outer periphery of the clamping end 21 is adapted to the inner periphery of the slot 111.

[0027] In this embodiment, a clamping end 21 is provided at one end of the belt rigging 2, and a metal pin 211 is provided inside the clamping end 21, which can improve the strength and rigidity of the clamping end 21. The clamping end 21 with the pin 211 inside is inserted into the slot 111 of the pulley section 11, so as to realize the connection between the belt rigging 2 and the pulley body 1, and the connection process does not require the aid of other tools, which is convenient for operation. The connected belt rigging 2 passes through the lead-out port 112 and is wrapped around the outer periphery of the pulley section 11.

[0028] In addition, the shape design of the clamping portion 1111 makes the maximum width of the clamping end 21 adapted thereto greater than the width of the outlet 112, which can effectively prevent the clamping end 21 from coming out of the outlet 112 under the action of external force, which is beneficial to improving the connection reliability of the belt sling 2 and the pulley body 1. In practice, in order to further improve the connection reliability of the belt sling 2, it is necessary to ensure that the belt sling 2 is wound around the outside of the pulley section 11 for at least two times after passing through the outlet 112.

[0029] Furthermore, the pulley body 1 further includes a ratchet mounting section 12 and a bearing mounting section 13 in a direction away from the pulley section 11, and the outer diameters of the pulley section 11, the ratchet mounting section 12 and the bearing mounting section 13 decrease in sequence. Figure 3 and Figure 4 The ratchet mounting section 12 is used to mount the ratchet 3, and the bearing mounting section 13 is used to mount the bearing 4. The ratchet 3 is used to brake the pulley body 1 by engaging with the execution pawl 5 when the heavy object falls accidentally, thereby preventing the pulley body 1 from falling, and the bearing 4 is connected between the pulley body 1 and the housing 6, thereby realizing the relative rotation between the pulley body 1 and the housing 6. Specifically, the ratchet mounting section 12 is provided with an external thread, and the ratchet 3 is threadedly connected to the ratchet mounting section 12.

[0030] Furthermore, a keyway 114 is provided on the inner periphery of the pulley body 1, and the keyway 114 is used to be spline-connected with the power input shaft 7 to drive the pulley body 1 to rotate. A threaded hole 113 is provided at one end of the pulley section 11 away from the ratchet mounting section 12, and the threaded hole 113 is used to be screw-connected with the driving wheel 8, so that the driving wheel 8 can rotate synchronously with the pulley body 1, so as to serve as the power input end of other structures.

[0031] It should be noted that the pulley body 1 , the ratchet 3 , the bearing 4 , the actuating pawl 5 , and the driving wheel 8 are all installed in the housing 6 .

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
