Description

Technical Field

[0001] This utility model relates to the field of walking wheel technology, specifically a quick-release maintenance tool cart walking wheel. Background Technology

[0002] During routine inspections and maintenance of overhead cranes in the electrolysis workshop, personnel need to transport tools to the work site. Maintenance personnel need a special tool cart to transport tools and parts. The tool cart mainly consists of a push plate and wheels.

[0003] For example, the Chinese authorized patent CN111703480B (A Medical Trolley) includes a base, a push rod, front wheels, a steering mechanism, and rear wheels. The trolley's walking mechanism uses four traditional wheels without automatic steering. During turning, the steering mechanism adjusts the swing of the front wheels, which in turn drive the trolley to achieve the steering function. In this invention, when the trolley is turning on a sloping surface, compared to trolleys that rely solely on swivel wheels for steering, the external force required for steering is relatively small. Furthermore, compared to traditional medical trolleys, this trolley can transport heavy medical items and is more convenient and labor-saving to use than traditional medical trolleys with swivel wheels.

[0004] However, the existing walking wheels are fixed to the trolley with bolts at the top, and installation and disassembly require tools, which is time-consuming and laborious. Therefore, it does not meet the current needs. In response, we have proposed a quick-release maintenance tool trolley walking wheel. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-release maintenance tool trolley wheel to solve the problem mentioned in the background art that the top of the existing wheel is fixed to the trolley by bolts, and the installation and disassembly require tools, which is time-consuming and laborious.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-release maintenance tool cart wheel, comprising: a wheel frame, a universal wheel disk at the upper end of the wheel frame, a mounting seat at the upper end of the universal wheel disk, a limit seat at the upper end of the mounting seat, a connecting component at the upper end of the limit seat, and the connecting component being quick-releasely connected to the limit seat; an axle at the lower end of the wheel frame, with movable wheels rotatably connected to both ends of the axle.

[0007] Preferably, the connecting assembly includes a connecting seat, the front surface of which is provided with a connecting slot, and the lower surface of the connecting slot is open. The connecting slot is T-shaped, and both the mounting seat and the limiting seat are inserted along the connecting slot.

[0008] Preferably, the top surface of the connecting slot is provided with an extension groove, the top surface of the extension groove is provided with a second inner groove, and an iron sheet is embedded inside the second inner groove.

[0009] Preferably, the upper surface of the limiting seat is provided with a first inner groove, and a magnetic absorbing piece is embedded in the temporal part of the first inner groove, and the limiting seat is magnetically fixed to the iron sheet by the magnetic absorbing piece.

[0010] Preferably, the connecting assembly further includes a fixing plate, and the fixing plate is thermally fused to the connecting seat.

[0011] Preferably, the lower surface of the wheel frame is provided with an axle slot, one side surface of the axle is provided with a limiting side plate, and the limiting side plate is welded and fixed to the axle, and the limiting side plate and the axle are inserted along the axle slot.

[0012] Preferably, a bolt hole is provided at the center of one side surface of the limiting side plate, and a hexagonal bolt is provided on the side of the wheel frame near the bottom end, with one end of the hexagonal bolt passing through the wheel frame and threadedly connected to the bolt hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets a limiting seat at the upper end of the mounting seat, sets a connecting slot on one side surface of the connecting seat, and sets an extension groove on the top surface of the connecting slot. The mounting seat and the limiting seat are inserted along the connecting slot. When they move to the innermost end of the connecting slot, the mounting seat and the limiting seat move upward along the extension groove until they reach the top of the extension groove. In this way, when using the trolley, the weight of the trolley can press down on the connecting seat, thereby applying pressure to the wheel frame. The mounting seat and the limiting seat are located inside the extension groove, which has the effect of limiting and preventing separation. The wheel frame and the connecting seat are fixed by the downward pressure of the trolley itself, which facilitates the quick disassembly and installation of the wheel frame and the moving wheel, improving flexibility and convenience. The limiting side plate and the wheel axle are inserted along the wheel axle slot and fixed by hexagonal bolts. The wheel axle and the moving wheel can be disassembled as a whole, which is convenient for independent replacement after damage, improving convenience. This solves the problem that the top of the existing walking wheel is fixed to the trolley by bolts, and the installation and disassembly require tools, which is time-consuming and laborious.

[0015] (2) By embedding a magnetic piece inside the first recessed groove on the upper surface of the limiting seat, after the limiting seat moves upward along the extension groove to the top, the limiting seat is magnetically fixed to the iron piece by the magnetic piece, thereby assisting in fixing the wheel frame, avoiding separation of the wheel frame from the connecting seat on bumpy road sections, and further improving stability.

The connecting component 2 includes a connecting seat 10. A connecting slot 11 is provided on the front surface of the connecting seat 10, and the lower surface of the connecting slot 11 is open. The connecting slot 11 is T-shaped, and the mounting seat 5 and the limiting seat 6 are inserted along the connecting slot 11. The connecting component 2 also includes a fixing plate 12, and the fixing plate 12 is heat-fused to the connecting seat 10.

[0023] Place the connecting seat 10 at the bottom of the trolley plate and fix it to the trolley plate with the external bolts of the fixing plate 12. The trolley plate here is the loading plate of the trolley and is a component structure of the existing trolley.

[0024] After securing the connecting seat 10, the wheel frame 1 can be installed. During installation, both the mounting seat 5 and the limiting seat 6 are inserted along the connecting slot 11.Figure 2 As shown, since the connecting slot 11 is T-shaped, and the mounting seat 5 and the limiting seat 6 also form a T-shape, the connection stability is improved and it is not easy to fall off. When it moves to the innermost end of the connecting slot 11, the mounting seat 5 and the limiting seat 6 move upward along the extension groove 17 until they reach the top of the extension groove 17. In this way, when using the trolley, the weight of the trolley can press down on the connecting seat 10, thereby applying pressure to the wheel frame 1. The mounting seat 5 and the limiting seat 6 are located inside the extension groove 17, which plays a role in limiting and preventing separation. The wheel frame 1 and the connecting seat 10 are fixed by the downward pressure of the trolley itself, which facilitates the quick disassembly and installation of the wheel frame 1 and the moving wheel 3, improving flexibility and convenience.

[0025] The top surface of the connecting slot 11 is provided with an extension groove 17, the top surface of the extension groove 17 is provided with a second inner groove 18, the inside of the second inner groove 18 is embedded with an iron piece 19, the upper surface of the limiting seat 6 is provided with a first inner groove 8, the temporal part of the first inner groove 8 is embedded with a magnetic piece 7, and the limiting seat 6 is magnetically fixed to the iron piece 19 by the magnetic piece 7.

[0026] After the mounting base 5 and the limiting base 6 move upwards along the extension groove 17 to the top, the limiting base 6 is magnetically fixed to the iron plate 19 by the magnetic suction piece 7, as shown. Figure 2 and Figure 4 As shown, this provides auxiliary fixation for the wheel frame 1, preventing the wheel frame 1 from separating from the connecting seat 10 on bumpy roads and further improving stability;

[0027] The lower surface of the wheel frame 1 is provided with an axle slot 13. One side surface of the axle 14 is provided with a limiting side plate 15, and the limiting side plate 15 is welded and fixed to the axle 14. The limiting side plate 15 and the axle 14 are inserted along the axle slot 13. A bolt hole 16 is provided at the center of one side surface of the limiting side plate 15. A hexagonal bolt 9 is provided on the side of the wheel frame 1 near the bottom end, and one end of the hexagonal bolt 9 passes through the wheel frame 1 and is threaded to the bolt hole 16. The limiting side plate 15 and the axle 14 are inserted along the axle slot 13. The limiting side plate 15 has a limiting effect, preventing the axle 14 from rotating along the axle slot 13 and improving stability.

[0028] Then, one end of the hexagonal bolt 9 is threaded through the wheel frame 1 and connected to the bolt hole 16, thereby fixing the limiting side plate 15 and the wheel axle 14. The wheel axle 14 and the movable wheel 3 can then be disassembled, making it easy to replace them independently after damage and improving convenience.
