Description

Technical Field

[0001] This utility model belongs to the field of tile paving technology, specifically a walking wheel braking structure for a tile paving device. Background Technology

[0002] Currently, the laying of wall tiles in building construction and home decoration is mostly limited to manual laying, especially for large ceramic slabs with large area and weight, which requires a high number of workers and their technical experience. As a result, tile laying auxiliary devices that can assist workers in their work have appeared on the market.

[0003] To facilitate the free movement of the auxiliary paving device on the construction site, it is usually equipped with casters at the bottom. However, the construction site conditions are complex. If an emergency occurs while the auxiliary paving device is carrying the ceramic slab, such as if people or other construction equipment suddenly pass in front of it, the ceramic slab may break or even people may be injured if it cannot be effectively braked. Therefore, the wheels of the auxiliary paving device need to have a structure that can brake safely and efficiently.

[0004] Traditional swivel casters typically use brake pads on the caster, which are then braked by the user pressing a pedal to create friction between the caster and the brake pads. This method is inconvenient because the brake pads rotate with the caster. When braking is needed, the user has to find the brake pads and press them with their foot, which can be difficult to do in an emergency.

[0005] A traction-braking omnidirectional wheel, such as the one disclosed in CN104972832B, includes an omnidirectional wheel body and a braking device. The omnidirectional wheel body includes a support leg and a wheel rotatably connected to the support leg. The braking device includes a traction limiting hole opened inside the support leg and a brake pad rotatably connected to the support leg. A second traction rope is provided in the traction limiting hole. One end of the second traction rope extends from the upper part of the support leg, and the other end extends from the lower part of the support leg and is connected to the brake pad. A spring is sleeved on the part of the second traction rope extending from the lower part of the support leg. One end of the spring abuts against the brake pad, and the other end abuts against the support leg. The brake pad is pulled by the traction rope to brake, without the need for foot operation, thus achieving rapid braking.

[0006] However, the above method can only brake the wheels through the traction rope, and the support legs of the caster wheels can also rotate freely. When braking, the heavy body of the paving machine and the inertia of the tiles carried on the paving machine body can easily force the support legs to rotate, causing the paving machine body to deflect and vibrate, affecting the stability of the braking process. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, this invention addresses the technical problem of providing a convenient and simple operating method that, compared to traditional foot-operated braking, aligns with operator habits and facilitates rapid braking responses in emergency situations. Furthermore, the simple structure and low failure rate of this solution reduce operating and maintenance costs, making it suitable for long-term use in complex construction sites. By incorporating a spline pin, the brake cable core wire is tightened while the spline pin engages with the second spline groove, thereby locking the wheel frame's rotation. This achieves simultaneous braking of the wheels and locking of the wheel frame, preventing braking... The heavy tiling machine body and the inertia of the tiles carried on it force the wheel frame to rotate, thereby causing the tiling machine body to deflect and vibrate, thus ensuring the stability and safety of braking. By setting a brake cable, the operator can tighten the brake cable core by squeezing the operating handle, and then use the friction between the brake cable and the traveling wheel to brake the traveling wheel. When the operating handle is released, there is basically no friction between the brake cable core and the traveling wheel, so it does not affect the normal rolling of the traveling wheel. Furthermore, the operator can brake multiple traveling wheels simultaneously by operating the handle, thereby improving the braking effect.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a braking structure for the traveling wheels of a tile laying device, characterized in that the braking structure for the traveling wheels of the tile laying device includes: a laying machine body, a wheel seat fixedly connected to the bottom of the laying machine body, a wheel frame rotatably connected to the bottom side of each wheel seat, a traveling wheel rotatably connected to each wheel frame, and a braking component provided between each wheel seat, wheel frame and traveling wheel.

[0009] Furthermore, the braking component includes a brake cable, the core of which passes through the wheel seat and through the rotation axis of the wheel frame. A groove is provided on the outer side of the traveling wheel, and the core of the brake cable passes through the groove to brake the rotation of the traveling wheel. The end of the core of the brake cable is fixedly connected to the wheel frame.

[0010] Furthermore, a first spline groove is provided at the rotation axis of the wheel frame, and a second spline groove is provided on the wheel seat at the corresponding position of the first spline groove. A spline pin is slidably connected in the first spline groove, and the top end of the spline pin can engage with the second spline groove to lock the rotation of the wheel frame.

[0011] Furthermore, the top of the spline pin is conical, and the bottom of the spline pin has a cylindrical portion with a diameter smaller than that of the top of the spline pin. A fastener that is slidably connected to the cylindrical portion of the spline pin is fixedly connected to the bottom side of the wheel frame, and a spring is provided between the fastener and the bottom of the cylindrical portion of the spline pin.

[0012] Furthermore, a cover that is rotatably connected to the wheel frame is provided on the bottom side of the wheel seat, and a bracket is fixedly connected to the wheel seat above the spline pin. The conduit of the brake cable abuts against the bracket, and the core wire of the brake cable passes through the bracket.

[0013] Furthermore, the main body of the paving machine is provided with a handle, and two operating handles are symmetrically arranged on both sides of the handle. Each operating handle is connected to the two brake line ends on the same side.

[0014] In summary, compared with the prior art, the beneficial effects of this utility model are as follows: (1) This method is convenient and simple to operate. Compared with the traditional foot-operated braking method, it conforms to the operating habits of operators and is suitable for operators to respond quickly to braking in case of emergencies. In addition, the structure of this solution is simple and the failure rate is low, which reduces the cost of use and maintenance and is conducive to long-term use in complex construction sites.

[0015] (2) By setting a spline pin, the core wire of the brake line is tightened while the spline pin is inserted into the second spline groove, thereby locking the rotation of the wheel frame. This achieves the locking of the wheel frame while braking the traveling wheel, preventing the wheel frame from rotating due to the inertia of the heavy paving machine body and the tiles carried on the paving machine body during braking, which would cause the paving machine body to deflect and vibrate, thus ensuring the stability and safety of braking.

[0016] (3) By setting a brake line, the operator can tighten the brake line core by squeezing the operating handle, and then use the friction between the brake line and the traveling wheel to brake the traveling wheel. When the operating handle is released, there is basically no friction between the brake line core and the traveling wheel, so it does not affect the normal rolling of the traveling wheel. Furthermore, the operator can brake multiple traveling wheels simultaneously by operating the operating handle, thereby improving the braking effect. Attached Figure Description

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] like Figure 1-7 As shown, a walking wheel braking structure for a tile laying device includes a tile laying machine body 10, a handle 11 on the tile laying machine body 10, four wheel seats 14 symmetrically distributed on both sides of the bottom of the tile laying machine body 10, a cover 17 fixedly connected below each wheel seat 14, a wheel frame 15 rotatably connected inside each cover 17, and a walking wheel 16 rotatably connected to each wheel frame 15.

[0027] The wheel frame 15 can rotate freely on the bottom side of the wheel seat 14, and the walking wheels 16 meet the requirement of free movement of the tiling machine body 10. The operator can use the handle 11 to push the tiling machine body 10 to move freely on the ground. It is flexible, labor-saving, and can be operated by a single person to facilitate tile laying.

[0028] like Figure 1-7 As shown, each wheel seat 14 is provided with a brake line 13. The core wire of each brake line 13 passes through the wheel seat 14 and the rotation axis of the wheel frame 15. Each traveling wheel 16 has an annular groove 18 on its outer side. The core wire of the brake line 13 passes through the groove 18 and the end of the core wire is fixed to the wheel frame 15. Each wheel seat 14 is fixedly connected to a bracket 19 at the corresponding position of the brake line 13. Each bracket 19 abuts against the end of the wire tube of the brake line 13. The core wire of the brake line 13 passes through the bracket 19. Two operating handles 12 are symmetrically arranged on the handle 11. Each operating handle 12 is connected to the two brake lines 13 on the same side.

[0029] By setting a brake cable 13, the operator can tighten the core wire of the brake cable 13 by squeezing the operating handle 12. The friction between the brake cable 13 and the traveling wheel 16 will then brake the traveling wheel 16. When the operating handle 12 is released, there is basically no friction between the core wire of the brake cable 13 and the traveling wheel 16, so it does not affect the normal rolling of the traveling wheel 16. Furthermore, the operator can brake multiple traveling wheels simultaneously by operating the operating handle 12, thereby improving the braking effect.

[0030] The wheel groove 18 allows the brake cable 13 core wire to be embedded in the travel wheel 16, avoiding direct contact between the brake cable 13 core wire and the ground, thus preventing unnecessary wear. At the same time, it does not affect the rolling contact between the travel wheel 16 and the ground. The bracket 19 provides support for the brake cable 13 conduit, making it easy to tighten and loosen the brake cable 13 core wire.

[0031] Since the end of the brake cable 13 core wire is fixed on the wheel frame 15 and the brake cable 13 core wire passes through the rotation axis of the wheel frame 15, the brake cable 13 core wire will twist along with the wheel frame 15 during its free rotation, without affecting the rotation of the wheel frame 15.

[0032] This method is convenient and simple to operate, and compared with the traditional foot-operated braking method, it conforms to the operating habits of operators. It is suitable for operators to respond quickly to braking in emergency situations. In addition, the simple structure and low failure rate of this solution reduce the cost of use and maintenance, which is conducive to long-term use in complex construction sites.

[0033] like Figure 1-7 As shown, a first spline groove 23 is provided at the rotation axis of the wheel frame 15, and a second spline groove 24 is provided on the wheel seat 14 at the corresponding position of the first spline groove 23. A spline pin 20 is slidably connected in the first spline groove 23. The top of the spline pin 20 can engage with the second spline groove 24 to lock the rotation of the wheel frame 15. The top of the spline pin 20 is conical, and the bottom of the spline pin 20 is provided with a cylindrical part with a diameter smaller than the diameter of the top of the spline pin 20. A fastener 22 is fixedly connected to the bottom side of the wheel frame 15 and slidably connected to the cylindrical part of the spline pin 20. A spring 21 is provided between the fastener 22 and the bottom of the cylindrical part of the spline pin 20.

[0034] By setting the spline pin 20, the core wire of the brake line 13 is tightened while the spline pin 20 is inserted into the second spline groove 24, thereby locking the rotation of the wheel frame 15. This achieves the goal of locking the wheel frame 15 while braking the traveling wheel 16, preventing the wheel frame 15 from rotating due to the inertia of the heavy tiling machine body 10 and the tiles carried on the tiling machine body 10, which would cause the tiling machine body 10 to deflect or vibrate. This ensures the stability and safety of braking.

[0035] By setting spring 21 and clip 22, when the brake cable 13 core wire needs to be loosened, the elasticity of spring 21 can be used to reset the brake cable 13 core wire to a loose state, and the spline pin 20 can be automatically disengaged from the second spline groove 24. This allows the operator to unlock the wheel frame 15 and the travel wheel 16 by simply releasing the operating handle 12.

[0036] The working principle of this embodiment is as follows: Under normal conditions, the brake line 13 core wire is in a relaxed state, the spring 21 is not compressed, and the operator can hold the handle 11 to push the tiling machine body 10 to move freely, thereby carrying out the tile laying work. If an accident occurs during this process, the operator can directly squeeze the operating handle 12 to tighten the brake line 13 core wire, so that the brake line 13 core wire tensions the traveling wheel 16, and uses the friction between the brake line 13 and the traveling wheel 16 to brake the traveling wheel 16.

[0037] At the same time, the spline pin 20 is pulled up, causing it to enter the second spline groove 24 and engage with it. The spring 21 is compressed and stores elastic potential energy, thereby connecting the wheel frame 15 and the wheel seat 14 together and locking the rotation of the wheel frame 15. The tapered top of the second spline groove 24 makes the process smoother and prevents the spline pin 20 from getting stuck at the edge of the second spline groove 24, which would prevent braking.

[0038] After braking, when the operator releases the operating handle 12, the spring 21 releases its elastic force, which causes the brake cable 13 to return to a relaxed state. Simultaneously, the spline pin 20 descends and disengages from the second spline groove 24, thus releasing the lock on the rotation of the wheel carrier 15.
