Description

Technical Field

[0001] The utility model relates to the field of tool boxes, in particular to a tool cart with a guiding function. Background Art

[0002] Currently, during factory equipment maintenance, workers typically need to carry a large number of specialized tools. The existing method is to place the tools on a tool cart, which the worker pushes forward. Once the cart reaches the designated location, the worker stops the cart, removes the tools, and begins maintenance. However, when the equipment is large, workers often have to inspect it first, return to the tool cart, and then push it to the location where maintenance is needed. Furthermore, the repeated manual pushing of the tool cart between locations distracts workers and wastes their time, resulting in low work efficiency.

[0003] To this end, the prior art (announcement number: CN214565793U, announcement date: 2021.11.02) discloses a following tool cart, which places tools in a tool box, and locates the user's position relative to the tool cart by cooperating with a positioning base station and a positioning tag. Then, the PID controller calculates the angular velocity and linear velocity required for the tool cart to follow based on the relative position. The central processing unit controls the drive motor, and the drive motor causes the wheel group to move according to the required angular velocity and linear velocity to realize the following of the tool cart. In actual maintenance work, the staff places the workpiece in the tool box. During the maintenance process, the tool cart follows the staff. When equipment problems are found or the equipment needs to be disassembled, the staff can easily remove the tools from the tool box and perform maintenance work, which effectively improves work efficiency.

[0004] However, the control method of this solution is relatively complicated, and most of the equipment in the workshop is arranged in an array. During maintenance, it is only necessary to move the tool cart to the position of the corresponding equipment. Since the tool cart of the existing solution is not equipped with a conveying track, a more complex control scheme must be set up if it is to have a following function. Therefore, it is necessary to design a lower-cost tool cart that can guide transportation to address this defect. Utility Model Content

[0039] like Figure 1-6 As shown, a tool cart with a guiding function of the present invention comprises a base 2, and the base 2 slides on the ground 1;

[0040] Two universal wheels 3 and two guide wheels 4 are fixedly mounted on the bottom side of the base 2. A sliding track 5 is formed on the ground 1. The two guide wheels 4 are installed in the sliding track 5 with a clearance fit. The two universal wheels 3 are in contact with the ground 1.

[0041] A driving mechanism 6 is fixedly mounted in the middle of the base 2. A wheel groove 7 is formed in the middle of the base 2. The bottom side of the driving mechanism 6 passes through the wheel groove 7 and abuts against the ground 1.

[0042] A battery 8 and an electrical controller 9 are fixedly installed in the base 2, and the battery 8 supplies power to the driving mechanism 6 through the electrical controller 9;

[0043] The principle is as follows: a sliding track 5 is set on the ground 1, and the base 2 can slide on the sliding track 5 of the ground 1 through two guide wheels 4 on the bottom side. The sliding track 5 can be set according to the on-site workshop, so that the tool cart can slide to the corresponding equipment that needs to be repaired, which is convenient for use; in addition, the driving mechanism 6 can be used to drive the base 2 to slide, and the automatic operation of the driving mechanism 6 is realized through the electrical controller 9 to achieve automatic following. Since there is no need to be equipped with a steering mechanism when following, the control method is simpler, thereby effectively reducing the manufacturing cost and the time for editing the control program; in addition, one or more arc-shaped track structures can be set on the sliding track 5 according to the on-site workshop, and when the tool cart turns, it will turn through the universal wheel 3, which is convenient for actual use.

[0044] Further: the driving mechanism 6 includes a wheel frame 61, a buffer frame 62, a hub frame 63 and a hub motor 64, the buffer frame 62 is installed on the bottom side of the wheel frame 61, the hub frame 63 is rotatably installed on the bottom side of the buffer frame 62, the hub motor 64 is rotatably installed in the hub frame 63, and the bottom side of the hub motor 64 passes through the wheel groove 7 and abuts against the ground 1; the hub motor 64 can be used to drive the base 2 to move, and since the hub frame 63 is rotatably fitted on the bottom side of the buffer frame 62, it can be turned according to the arc track on the sliding track 5, which is convenient for implementing the movement control of the tool vehicle.

[0045] Furthermore: the four ends of the buffer frame 62 are provided with mounting bolts 10, the bottom ends of the mounting bolts 10 press against the bottom side of the buffer frame 62, and the top ends of the mounting bolts 10 are fixedly mounted on the wheel frame 61, and a spring 11 is installed in contact between the wheel frame 61 and the buffer frame 62; the spring 11 can be used to keep the bottom side of the hub motor 64 pressed against the ground 1 at all times to achieve stable drive control.

[0053] Furthermore: a starting point IC card 22 and an end point IC card 23 are respectively set on the ground at both ends of the sliding track 5. When the base 2 moves to both ends of the sliding track 5, the electrical controller 9 and the starting point IC card 22 or the end point IC card 23 are wirelessly connected and sensed with each other; when it moves to the extreme position, it can automatically sense and stop moving, which is convenient for actual control and use.

[0054] The present invention can be used in conjunction with a remote control, and can be set as a positioning bracelet worn on the hand, or as a belt worn around the waist. The base station positioning module 21 can be set to the sensing range of the remote control. After the remote control leaves the set range, the drive mechanism 6 will be controlled to drive the tool cart to move, and move to find the middle of the remote control to the base station positioning module 21. The starting point and the end point can be identified by RFID. At the same time, there are obstacle avoidance radars 18 at both ends. The sensing range can be set as needed to avoid collisions with obstacles and people. At the same time, a human radar detector 20 is also provided. When a person approaches the tool cart, it can be set as needed to make the tool cart automatically stop moving, thereby making it convenient for people to take tools and other items on the tool cart.
