[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) In the present invention, when the hook needs to be lowered, the extended end of the cylinder is started to contract, and the contraction of the extended end of the cylinder drives the connecting rope to move downward, and the downward movement of the connecting rope drives the pawl to rotate downward, so that the pawl is not engaged with the ratchet wheel, and the rotation of the pawl compresses the spring. At this time, the main body of the electric hoist is started to rotate forward, and the rotating shaft is rotated forward by the forward rotation of the main body of the electric hoist, and the steel rope and the hook are driven to move downward by the forward rotation of the rotating shaft. When the hook is lowered, the extended end of the cylinder can be started to extend, and the connecting rope is reset by the resetting of the cylinder. The resetting of the connecting rope causes the spring to reset by its own elastic action, so that the pawl is always engaged with the ratchet wheel. At this time, the rotating shaft can be reversed to pull the hook upward. Since the engagement of the ratchet and the pawl will rotate the rotating shaft in one direction, the pawl will not block the rotation of the ratchet wheel when the rotating shaft is reversed, and the engagement of the ratchet and the pawl can prevent the rotating shaft from rotating forward, thereby preventing the phenolic adhesive ingredients from falling, thereby preventing safety hazards during the transportation of the phenolic adhesive ingredients.

[0036] In this embodiment, the hook 4 is used to hang the phenolic adhesive ingredients, and the rotating shaft 5 is used to connect with the limiting mechanism. The limiting mechanism is convenient for limiting the rotating shaft 5. In the utility model, the engagement of the ratchet 6 and the pawl 7 will cause the rotating shaft 5 to rotate in one direction, so the pawl 7 will not block the rotation of the ratchet 6 when the rotating shaft 5 is reversed, and the engagement of the ratchet 6 and the pawl 7 can prevent the rotating shaft 5 from rotating forward, thereby preventing the phenolic adhesive ingredients from falling, and preventing safety hazards from occurring during the transportation of the phenolic adhesive ingredients.

[0037] Specifically, the limiting mechanism includes a one-way component and an opening and closing component. Both the one-way component and the opening and closing component are arranged on the electric hoist body 1, and the one-way component and the opening and closing component are connected.

[0038] In this embodiment, the limiting mechanism includes a one-way component and an opening and closing component. The one-way component and the opening and closing component are both arranged on the electric hoist body 1, and the one-way component and the opening and closing component are connected.

[0039] Specifically, the one-way component includes a ratchet 6, a pawl 7, a support plate 8 and a spring 9. The ratchet 6 is installed on the surface of the rotating shaft 5. The pawl 7 is rotatably connected to the side end of the electric hoist body 1 through the rotating shaft. The support plate 8 is fixedly connected to the side end of the electric hoist body 1. The spring 9 is fixedly connected between the support plate 8 and the pawl 7.

[0040] In this embodiment, the support plate 8 is used to fix the spring 9. The spring 9 uses its own elasticity to keep the pawl 7 and the ratchet wheel 6 always engaged, thereby limiting the rotation shaft 5 in one direction to facilitate the unidirectional rotation of the rotation shaft 5.

[0041] Specifically, the opening and closing assembly includes a through hole 10, a support 11, a cylinder 12 and a connecting rope 13. The through hole 10 is opened on the support plate 8, the support 11 is installed on the side end of the electric hoist body 1, the cylinder 12 is fixedly connected to the front end of the support 11, the connecting rope 13 is fixedly connected between the extended end of the cylinder 12 and the pawl 7, and the connecting rope 13 movably passes through the through hole 10.

[0042] In this embodiment, the through hole 10 is provided to facilitate the passage of the connecting rope 13, and the support 11 is provided to facilitate the installation of the cylinder 12. The extended end of the cylinder 12 is started to contract, and the contraction of the extended end of the cylinder 12 drives the connecting rope 13 to move downward, and the downward movement of the connecting rope 13 drives the pawl 7 to rotate downward.

[0043] Specifically, a connecting plate 2 is fixedly connected to the electric hoist body 1 , and a mobile device 3 is installed on the connecting plate 2 .

[0044] In this embodiment, the connecting plate 2 is for facilitating the installation of the moving device 3, and the moving device 3 is for facilitating the electric hoist body 1 to move on the gantry. It should be noted that the moving device 3 is a prior art in the art.

[0046] In this embodiment, a protective shell 14 is installed at the side end of the electric hoist body 1, and the protective shell 14 is convenient for protecting the limiting mechanism.

[0047] Working principle: When the hook 4 needs to be lowered, the extended end of the cylinder 12 is started to contract, and the contraction of the extended end of the cylinder 12 drives the connecting rope 13 to move downward, and the downward movement of the connecting rope 13 drives the pawl 7 to rotate downward, so that the pawl 7 is not engaged with the ratchet 6. The rotation of the pawl 7 compresses the spring 9. At this time, the electric hoist body 1 is started to rotate forward, and the rotating shaft 5 rotates forward through the forward rotation of the electric hoist body 1. The forward rotation of the rotating shaft 5 drives the steel rope and the hook 4 to move downward. When the hook 4 is lowered, the extended end of the cylinder 12 can be started to extend The cylinder 12 is reset to drive the connecting rope 13 to reset. The reset of the connecting rope 13 resets the spring 9 through its own elastic action, so that the pawl 7 is always engaged with the ratchet 6. At this time, the reversal of the rotating shaft 5 can pull the hook 4 upward. Since the engagement of the ratchet 6 and the pawl 7 will cause the rotating shaft 5 to rotate in one direction, the pawl 7 will not prevent the ratchet 6 from rotating when the rotating shaft 5 is reversed, and the engagement of the ratchet 6 and the pawl 7 can prevent the rotating shaft 5 from rotating forward, thereby preventing the phenolic adhesive ingredients from falling, and preventing the problem of safety hazards during the transportation of the phenolic adhesive ingredients.
