[0024] This utility model provides a non-powered mobile raw material filter replacement device for para-aramid fibers, see reference. Figures 1-3The system includes a lifting device 1 and a raw liquid filter element 2. The lifting device 1 includes a base 11 and a lifting mechanism 12. The base 11 is movable. The lifting mechanism 12 includes a boom 121, a telescopic boom 122, a wire rope 123, and a hook 124. The boom 121 is fixedly connected to the base 11, and the telescopic boom 122 is movably connected to the top end of the boom 121. The boom 121 is equipped with a rocker control device 125. The hook 123 is connected to the telescopic boom 122 and the rocker control device 125 in sequence through the wire rope 124. The length of the wire rope 123 is adjusted by the rocker control device 125 to control the lifting and lowering of the hook 124. The raw liquid filter element 2 includes a raw liquid filter element body 21 and a raw liquid filter element cap 22 fixed on the raw liquid filter element body 21. The raw liquid filter element cap 22 is equipped with a lifting ring 221 that matches the hook 124. This utility model provides a non-powered mobile raw material filter replacement device for para-aramid fibers. Through the movement of the base 11, the rotation of the boom, the adjustment of the height and angle of the telescopic arm 122, and the length adjustment of the wire rope 123 via the rocker control device 125, the device allows for quick alignment of the hook 124 with the raw material filter 2 without personnel contact with the raw material. Since the raw material filter cap 22 has a lifting ring 221 that matches the hook 124, the fixed engagement between the hook 124 and the lifting ring 221 easily enables the lifting and replacement of the raw material filter 2. The movable connection can be hinged. The diameter and allowable tensile force of the wire rope 123 are determined based on the weight of the raw material filter and the lifting height. The structure of the rocker control device 125 is not particularly limited; it only needs to achieve the corresponding function. For example, a common hand-cranked winch structure can be used.

[0025] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 The telescopic arm 122 includes a basic arm 122a and an arm sleeve 122b. One end of the arm sleeve 122a is hinged to the top of the main arm 121, and the other end is fitted onto the outer side of the head end of the basic arm 122a. The basic arm 122a is provided with a telescopic pin 122c, and the arm sleeve 122b is provided with a plurality of pin holes 122d that match the telescopic pin 122c. By engaging the telescopic pin 122c on the basic arm 122a with different pin holes 122d, the telescopic arm 122a can be adjusted. The number of telescopic pins is not particularly limited, as long as it meets the length adjustment requirements; typically, there are 3 to 6 pins. The distance between two adjacent telescopic pins can be the same or different.

[0026] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 A support rod 126 is provided between the arm sleeve 122b and the upper arm 121 for movable connection, so that the telescopic arm 122, the upper arm 121 and the support rod 126 form a stable triangular structure.

[0027] In some embodiments of this utility model, reference is made to Figure 3 The rocker control device 125 comprises a rocker arm 125a, a cable drum 125b, a large gear 125c, and a small gear 125d. The steel wire rope 124 is wound around the cable drum 125b. The rocker arm 125a is rigidly connected to the small gear 125d to drive its rotation. The small gear 125d meshes with the large gear 125c for transmission. The large gear 125c is coaxially fixed with the cable drum 125b, so that the rotation of the large gear 125c drives the cable drum 125b to wind and unwind the steel wire rope 124, achieving a power-free hand-cranked drive and eliminating the dependence on electricity in actual construction sites. In some preferred embodiments of this invention, the rocker arm 125a is mounted at the fixed midpoint of the large gear 125c and the small gear 125d. This reduces unnecessary components while also providing a speed-changing function, allowing operators to perform cable winding work more effortlessly. In this invention, the length of the rocker arm 125a is not particularly limited; it only needs to be easy to grip and effortless.

[0028] In some embodiments of this utility model, the rocker control device 125 is provided with a locking mechanism, which can brake in an emergency to prevent the telescopic arm 122 and the wire rope 123 from slipping and falling off when the raw liquid filter element 2 is replaced, thus protecting personnel and equipment.

[0029] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 The base 11 has two front wheels 111 and two rear wheels 112 below it. Both the front wheels 111 and the rear wheels 112 are omnidirectional casters, facilitating rapid movement and position adjustment of the device. In some preferred embodiments of this invention, the angle between the crossbeams of the front wheels 111 and the rear wheels 112 is 30°, resulting in better stability. In some preferred embodiments of this invention, the omnidirectional casters are made of wear-resistant nylon, adaptable to various complex road conditions, providing convenience and greater safety for on-site replacement of the raw material filter element. In this invention, the omnidirectional casters may also include a braking assembly and a locking assembly, facilitating fixation of the device after it has been moved to a specific position.

[0030] In some embodiments of this utility model, the basic arm 122a of the telescopic arm 122 is made of high-strength aluminum alloy, which is easy to move; the arm sleeve 122b is made of wear-resistant steel, which is wear-resistant and has good balance.

[0031] In some embodiments of this utility model, reference is made to Figures 1-3The upper end of the connection between the boom 121 and the telescopic boom 122 is provided with a first fixed pulley 127, the tail end of the telescopic boom is provided with a second fixed pulley 128, and the top of the hook 124 is provided with a movable pulley 129. The wire rope 123 passes through the movable pulley 129, the second fixed pulley 128, and the first fixed pulley 127 in sequence and is connected to the rocker control device 125. The length of the wire rope 123 can be controlled by the rocker control device 125, thereby realizing the lifting and lowering of the hook 124. There is no need for personnel to approach the raw liquid filter or touch the raw liquid filter element, which facilitates the replacement of the raw liquid filter element and ensures safety.

[0032] Working principle: The para-aramid non-powered mobile feedstock filter replacement device provided by this utility model is described in reference. Figures 1-3 Before use, select a suitable steel wire rope 123 according to the weight and lifting height of the raw liquid filter element 2 and complete the winding. Move the device to a suitable position, adjust the angle between the boom 121 and the telescopic boom 122, and adjust the basic arm of the telescopic boom 122 to a suitable length to facilitate alignment with the raw liquid filter element 2. Align the telescopic pin on the basic arm 122a with the pin hole 122d on the arm sleeve 122b and lock it in place. During use, first turn the rocker arm 125a of the rocker control device 125 to gradually increase the length of the steel wire rope 123, and the hook 124 gradually descends and connects with the lifting ring 221 on the raw liquid filter element cap 22. Then, turn the rocker arm 125a in the opposite direction to gradually raise the raw liquid filter element 2 away from the raw liquid filter housing A. After rising to a certain height, adjust the angle between the boom 121 and the telescopic boom 122 and move the base to bring the raw liquid filter element 2 above the designated placement position. Then, turn the rocker arm 125a again to lower it and place it in the designated position. Finally, the new raw liquid filter element 2 is lifted and placed into the raw liquid filter housing A to complete the replacement of raw liquid filter element 2.
