[0034] To make the above objects, features and advantages of the present invention more obvious and understandable, the specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0035] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0036] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0037] Embodiment 1

[0038] Refer to Figures 1 - 6 , this embodiment provides a belt assembly device for a hoist, including an installation module 100, an adjustment module 200 and a limit module 300. The setting of the adjustment module 200 can enable the moving disc 104 to move horizontally, which is a necessary condition for realizing the installation of the belt 105c. The setting of the limit module 300 can, during the installation process of the belt 105c, limit and fix the excess belt, avoiding the belt 105c from being wound during the installation process and affecting the installation progress.

[0039] Specifically, the installation module 100 includes an installation base 101. On the left side of the top of the installation base 101, there is an installation disc 102. On the right side of the top of the installation base 101, there is an installation frame 103. Inside the installation frame 103, there is a moving disc 104. Above the installation disc 102 and the moving disc 104, there is an installation component 105. The installation component 105 includes a first pulley 105a, a second pulley 105b, and a belt 105c. The first pulley 105a is rotatably connected to the top of the installation disc 102. The second pulley 105b is rotatably connected to the top of the moving disc 104. The belt 105c is sleeved on the outer surfaces of the first pulley 105a and the second pulley 105b.

[0040] The adjustment module 200 includes an installation plate 201 provided at the bottom of the installation base 101. Inside the installation plate 201, there is an adjustment component 202. The top of the adjustment component 202 is drivingly connected to a moving rod 203.

[0041] The limiting module 300 includes a limiting groove 301 opened on the inner wall of the installation frame 103. Inside the limiting groove 301, there is a limiting rod 302. The outer surface of the limiting rod 302 is slidably connected to a slider 303. One end of the slider 303 away from the limiting groove 301 is fixedly connected to a positioning block 304. The slider 303 can slide on the limiting rod 302. Therefore, the positioning block 304 can slide. Thus, when the positioning block 304 is dragged by the second pulley 105b, it can move along with it without affecting the normal assembly of the belt 105c.

[0042] Among them, the settings of the installation disc 102 and the moving disc 104 provide necessary conditions for the placement of the first pulley 105a and the second pulley 105b and for subsequent installation convenience. The setting of the installation frame 103 provides a support condition for the installation of the limiting module 300. The adjustment component 202 provides a power source for the moving rod 203. During the operation of the adjustment component 202, it can drive the moving rod 203 to move horizontally. The moving rod 203 can drive the moving disc 104 and the second pulley 105b to move horizontally.

[0043] Further, the adjusting component 202 includes a handlebar 202a arranged on the outer right side of the mounting plate 201. A rotating rod 202b is fixedly connected to the left end of the handlebar 202a. The left end of the rotating rod 202b penetrates through the outer wall of the mounting plate 201 and extends into its interior to be fixedly connected with a driving gear 202c. The upper end of the driving gear 202c is meshed and connected with a driven gear 202d. The left end of the driven gear 202d is fixedly connected with a threaded rod 202e through a connecting rod. A moving block 202f is threadedly connected to the outer surface of the threaded rod 202e. A moving rod 203 is fixedly connected to the top end of the moving block 202f. The top end of the moving rod 203 penetrates through the inner top wall of the mounting seat 101 and extends to its upper end to be connected with the bottom of the moving disc 104.

[0044] During use, the staff rotates the handlebar 202a. During the rotation of the handlebar 202a, the driving gear 202c can be driven to rotate through the rotating rod 202b. The driving gear 203c can drive the driven gear 202d and the threaded rod 202e to rotate. The moving block 202f threadedly connected to the threaded rod 202e can move to the right. The moving block 202f can drive the moving disc 104 to move to the right through the moving rod 203 at the top end.

[0045] Further, a positioning cavity 305 is opened at the center of the positioning block 304. A positioning component 306 is arranged inside the positioning cavity 305. A cover plate 307 is hinged to the top end of the positioning cavity 305. After the cover plate 307 is opened and the belt 105c is placed into the positioning cavity 305, the positioning component 306 can clamp and fix the belt, thereby preventing the belt from slipping and affecting the assembly work.

[0046] Specifically, the positioning component 306 includes a limiting block 306a movably connected inside the positioning cavity 305. A telescopic spring 306b is fixedly connected to one side of the limiting block 306a. The other side of the telescopic spring 306b is fixedly connected to the inner wall of the positioning cavity 305. A rotating block 306c is rotatably connected to the top end of the limiting block 306a. A telescopic block 306d is movably connected above the rotating block 306c. A pull rod 307a is arranged at the bottom end of the cover plate 307. The top end of the telescopic block 306d is slidably sleeved on the outer surface of the pull rod 307a.

[0047] Combined with Figure 5 and Figure 6As shown in the figure, when the staff member opens the cover plate 307, the pull rod 307a at the bottom end of the cover plate 307 can pull the telescopic block 306d to move obliquely upward. The rotating block 306c connected to the telescopic block 306d will rotate at a certain angle. And when the bottom end of the telescopic block 306d is tightened with the rotating block 306c, the telescopic block 306d can drag the rotating block 306c to move backward on the surface of the pull rod 307a. At this time, the rotating block 306c can drive the rear end of the limiting block 306a and the telescopic spring 306b to move, squeezing the telescopic spring 306b. At the same time, the space of the positioning cavity 305 inside the positioning block 304 is increased. At this time, it is very easy for the staff member to put the belt 105c into the positioning cavity 305. And after closing the cover plate 307, under the resilience of the telescopic spring 306b, the positioning block 304 can be bounced back to the initial position, thereby limiting and fixing the belt 105c, providing guarantee for the subsequent assembly work.

[0048] Embodiment 2

[0049] The present invention also provides a belt assembly method for a hoist, including the following steps: [[ID=⑧]]

[0050] S1: Install the first pulley 105a on the mounting plate 102, and install the second pulley 105b on the moving plate 104;

[0051] S2: Open the cover plate 307 at the top end of the positioning block 304. First, sleeve the belt 105c onto the first pulley 105a, and the other side is sleeved on the second pulley 105b. Then put the excess belt 105c into the positioning cavity 305 of the positioning block 304, and cover the cover plate 307;

[0052] S3: Rotate the turning handle 202a to make the adjustment module 200 operate, driving the moving plate 104 to move to the right. The moving plate 104 drives the second pulley 105b at the upper end to move to the right. During the movement, the excess belt 105c on the right side will gradually fit on the inner wall of the second pulley 105b;

[0053] S4: When the right side of the belt 105c is completely fitted and tightened with the second pulley 105b, the installation between the belt and the two pulleys is completed.

[0054] Among them, in step 1, a rotating space adapted to the first pulley 105a is provided at the top end of the mounting plate 102. Therefore, the first pulley 105a can rotate at the top end of the mounting plate 102. A clamping post is provided at the top end of the moving plate 104. When the second pulley 105b is placed on the moving plate 104, during the movement of the moving plate 104, the second pulley 105b can be driven to move through the clamping post;

[0055] In Step 3, during the rotation of the throttle grip 202a, the rotating rod 202b can drive the driving gear 202c to rotate. The driving gear 203c can drive the driven gear 202d and the threaded rod 202e to rotate. The moving block 202f threadedly connected to the threaded rod 202e can move to the right, and the moving block 202f can drive the moving disk 104 to move to the right through the moving rod 203 at the top.
