Description

Technical Field

[0001] This utility model belongs to the field of metal fiber winding technology, and in particular relates to an electric transport trolley. Background Technology

[0002] During the production of metal fiber filaments, multiple filaments need to be wound together to form multiple strands, which facilitates the subsequent connection of the spools. When winding the filaments, a transport trolley is usually used. The spools are placed on the transport trolley, and the metal fiber filaments wound on the spools are fixed and hung on the winding post. Then, the trolley is pushed to move around the winding post in a circular motion to wind the metal fiber filaments onto the outer wall of the winding post.

[0003] Existing transport trolleys for metal fiber production mainly consist of a trolley body, casters for assisting the trolley body's movement, and a mounting frame for carrying the metal fiber spools. The trolley body is also equipped with ropes that attach it to the outer wall of the winding post, thereby positioning the trolley's circumferential radius. When the transport trolley is pushed to transport metal fiber spools, the ropes and winding post limit the movement, causing the metal fiber spools on the transport trolley to wind around the winding post.

[0004] The aforementioned trolley for producing metal fiber filaments carries multiple spools wound with metal fiber filaments. During winding and unwinding, the spools rotate, but the rotation speed, i.e., the unwinding speed, is uncontrollable, resulting in loosely wound metal fiber filaments on the winding post. Furthermore, the trolley itself is heavier due to the multiple spools, placing significant work pressure and burden on the operators. Therefore, we provide an electric transport trolley to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide an electric transport trolley. By utilizing a walking mechanism, the trolley body can move along a track, thereby achieving the effect of traction of metal fiber filaments to be wound onto a winding post. By utilizing a carrying mechanism, not only can the spools be mounted, but multiple spools can also be positioned at different heights to avoid interference between the metal fiber filaments during winding. The rotating motor on it can control the unwinding speed of the metal fiber filaments, thus solving the problems of existing transport trolleys used for metal fiber filament production.

Detailed Implementation

[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Example 1

[0028] Please see Figure 1-3 This utility model is an electric transport trolley, including a vehicle body 1. The vehicle body 1 is connected to the travel track 6 through a walking mechanism 2, so that the vehicle body 1 can move along the travel track 6.

[0029] Specifically, a travel track 6 is provided below the vehicle body 1, and a power supply line 7 is installed above the vehicle body 1. The power supply line 7 is connected to the pantograph 501 through the brush 502 in the power receiving mechanism 5. The pantograph 501 is connected to the terminal block 501a on the vehicle body 1 through the power transmission line.

[0030] Furthermore, the upper side wall of the vehicle body 1 is provided with an installation groove 101, and a protective cover 4 is detachably and fixedly installed in the installation groove 101, and the wiring post 501a is installed on the protective cover 4. Example 2

[0031] Please see Figure 4-5Based on embodiment 1, a walking mechanism 2 is also provided, which can provide power support for the movement of the vehicle body 1 by utilizing the auxiliary walking component 201 and the power walking component 202 that are installed in the traveling track 6.

[0032] Specifically, the auxiliary walking component 201 includes a wheel frame 201b fixedly installed on the bottom side wall of the front of the vehicle body 1, and an auxiliary wheel 201a is rotatably connected to the wheel frame 201b. The rear of the vehicle body 1 is equipped with a power walking component 202, which includes an axle 202b located at the bottom of the vehicle body 1, and two power wheels 202a are installed on the axle 202b. A grooved wheel 202c is fixedly installed at the center of the axle 202b. The grooved wheel 202c is synchronously connected to the grooved wheel 203d in the drive component 203 via a belt 202d. At the same time, the grooved wheel 203d is also fixedly installed on a rotating rod 203c, which is connected to a power motor 203a via a coupling.

[0033] Furthermore, a bottom groove 102 is provided below the protective cover 4 and on the vehicle body 1. The bottom groove 102 is used for the belt 202d to pass through. At the same time, the power motor 203a in the drive assembly 203 is connected to the upper side wall of the vehicle body 1 through the frame 203b. The upper end of the bottom groove 102 is equipped with a mounting plate 103. The mounting plate 103 is rotatably connected to the rotating rod 203c. The groove wheel 203d is set in the groove of the mounting plate 103.

[0034] The operation process of this embodiment is as follows: When in use, the power motor 203a works, which drives the rotating rod 203c on the shaft end to rotate. When it rotates, the grooved wheel 203d installed on it also rotates. Then, with the cooperation of the belt 202d and the grooved wheel 202c, the wheel axle 202b also rotates, which drives the power wheel 202a to rotate. And because of the limiting effect of the travel track 6, the power wheel 202a can only move in the travel track 6, thereby driving the vehicle body 1 to move along the trajectory of the travel track 6. Example 3

[0035] Please see Figure 6 Based on Embodiments 1 and 2, a support mechanism 3 is also provided. The height of the support rod 303 on the shaft end can be adjusted by using the electric rod 301, so that different metal fiber spools are at different height positions, avoiding mutual interference during winding. The rotation speed of the support rod 303 can be controlled by using the rotary motor 302 on the support rod 303, thereby achieving the effect of adjusting the unwinding speed of the metal fiber spool.

[0036] Specifically, the electric rod 301 in the bearing mechanism 3 is fixedly connected to the mounting hole 104 on the vehicle body 1 through the first fixing bracket 301a. The shaft end of the electric rod 301 is connected to the rotary motor 302 through the second fixing bracket 302a. At the same time, the shaft end of the rotary motor 302 is connected to the bearing rod 303 through a coupling.

[0037] Furthermore, a tray 303a is fixedly installed on the lower middle outer wall of the support rod 303, and two opposing side grooves 303b are opened on the outer wall of the support rod 303 on the upper side of the tray 303a. A side hole 303c is opened on the inner wall of the side groove 303b, and a spring 303d is fixedly installed in the side hole 303c. The side hole 303c is connected to the abutment plate 303e through the spring 303d.

[0038] The operation process of this embodiment is as follows: In use, align the bottom of the metal fiber spool to be wound with the support rod 303, and press the abutment plate 303e inward to compress the spring 303d on its rear side. At this time, the abutment plate 303e retracts into the side groove 303b. Then, insert the metal fiber spool into the support rod 303. At this time, the spring 303d extends, bringing the abutment plate 303e on its shaft end close to the inner wall of the metal fiber spool and abutting against it. After the metal fiber spool is fixed and installed, the electric rod 301 moves up and down, causing the rotary motor 302 on the shaft end and the support rod 303 with the metal fiber spool installed to be misaligned. Finally, the end of the wire on the metal fiber spool is fixed to the winding post, and the rotary motor 302 is started, which rotates the support rod 303 with the metal fiber spool installed, so that the metal fiber spool can be unloaded.
