Description

Technical Field

[0001] The utility model relates to the technical field of transport vehicle equipment, in particular to a wheel used for a transport vehicle. Background Art

[0002] A transport truck is a piece of logistics equipment used to transport goods. It uses different power sources and technical means to help complete the loading and unloading, stacking and short-distance transportation of goods.

[0003] Among them, the manual truck is the most basic type of truck, which mainly relies on manpower to transport goods. Although the degree of automation and intelligence is not high, it has made important contributions to the transition from manual handling to mechanized handling, and still has a place in today's market. It has the characteristics of simple structure and easy use for temporary handling.

[0004] The wheel system of existing manual transport trucks is often not equipped with a relevant braking system. When transporting goods on a sloping road, the lack of a corresponding braking system will cause landslides. In addition, when the goods being transported are heavy, the inability to brake when they slide will cause dangerous situations in use, and in serious cases will threaten the users. Therefore, it is necessary to design a transport truck wheel with a matching braking system. For this purpose, we propose a wheel for a transport truck. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art and proposes a wheel for a transport vehicle.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A wheel for a transport vehicle, comprising a transport vehicle axle rod and a wheel hub, a connecting rod fixedly connected between the transport vehicle axle rod and the wheel hub, a tire is sleeved on the outer side of the wheel hub, and a brake mechanism is matched with the inner side of the wheel hub; the brake mechanism comprises a ring disc, a mounting seat is fixedly connected to the upper side of the ring disc, a left side seat is fixedly mounted on the left side of the ring disc, a first hydraulic rod is mounted on the left side seat, a brake seat is mounted on the output end of the first hydraulic rod, a brake pad is mounted on the brake seat, a right side seat is fixedly mounted on the right side of the ring disc, a second hydraulic rod is fixedly mounted on the right side seat, a hydraulic oil pipe is connected between the first hydraulic rod and the second hydraulic rod, a foot pedal is fixedly mounted on the output end of the second hydraulic rod, and a return spring is mounted between the foot pedal and the right side seat.

[0008] Preferably, the tire is a solid-belly explosion-proof tire and is provided with an anti-skid groove.

[0009] Preferably, a plurality of connecting rods are provided and the connecting rods are evenly distributed along the circumference of the inner ring of the wheel hub.

[0010] Preferably, the mounting seat is provided with a plurality of mounting holes, and the mounting holes are circular holes.

[0011] Preferably, the annular disk is sleeved on the outside of the axle rod of the transport vehicle, and the inner diameter of the annular disk is larger than the outer diameter of the axle rod of the transport vehicle.

[0012] Preferably, the brake seat and the brake pad both have L-shaped structural cross-sections.

[0013] Preferably, the return spring is sleeved on the outside of the second hydraulic rod and the inner side of the return spring does not contact the outer side of the second hydraulic rod.

[0014] Preferably, the foot pedal is provided with anti-slip convex teeth.

[0015] In the utility model, a wheel for a transport vehicle is provided with a brake mechanism, and a power design of double hydraulic rods is adopted in the brake system. When the transport vehicle slides during use, a foot pedal can be stepped on, and the foot pedal drives the second hydraulic rod to descend. When the second hydraulic rod retracts, the hydraulic oil in its working oil chamber is transported to the oil chamber in the first hydraulic rod through the hydraulic oil pipe, and the output end of the first hydraulic rod drives the brake seat and the brake pad installed on the side to abut against the wheel hub. Under the action of the brake pad, a braking friction force is generated on the wheel hub, and its The middle brake pad adopts an L-shaped design, which increases the contact area between the brake pad and the wheel hub, increases the friction, and makes the braking more stable. In addition, a return spring is installed at the bottom of the pedal. When the pedal is released, the rebound force of the return spring will lift the pedal, and then the brake pad will retract away from the wheel hub. At this time, the wheel hub loses the braking friction. The above structural design is the same as the point braking principle when using a car. The brake setting of the transport vehicle is combined with the braking principle of the car, which improves the practicability of actual use, enables the transport vehicle to perform braking operations in time when in use, and improves safety of use.

[0016] The utility model has a reasonable design. Through the provided brake mechanism, the brake system in the transport vehicle is combined with the braking principle of the automobile, so that the actual practicability is enhanced. At the same time, the braking operation can be performed in time during transportation, and the braking effect is automatically lost by the reset effect of the reset spring when not in use. The safety of use is improved while the convenience of actual operation is also taken into consideration. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-3 A wheel for a transport vehicle comprises a transport vehicle axle rod 1 and a wheel hub 3, a connecting rod 2 is fixedly connected between the transport vehicle axle rod 1 and the wheel hub 3, a tire 4 is sleeved on the outer side of the wheel hub 3, a brake mechanism 6 is matched on the inner side of the wheel hub 3, a plurality of connecting rods 2 are arranged and the connecting rods 2 are evenly distributed along the circumference of the inner ring of the wheel hub 3.

[0023] In this embodiment, the brake mechanism 6 includes an annular disc 61, a mounting seat 62 is fixedly connected to the upper side of the annular disc 61, a plurality of mounting holes 63 are opened on the mounting seat 62, and the mounting holes 63 are circular holes. A left side seat 64 is fixedly installed on the left side of the annular disc 61, a first hydraulic rod 65 is installed on the left side seat 64, a brake seat 66 is installed on the output end of the first hydraulic rod 65, and a brake pad 67 is installed on the brake seat 66. A right side seat 68 is fixedly installed on the right side of the annular disc 61, a second hydraulic rod 69 is fixedly installed on the right side seat 68, a hydraulic oil pipe 610 is connected between the first hydraulic rod 65 and the second hydraulic rod 69, a foot pedal 611 is fixedly installed on the output end of the second hydraulic rod 69, and a return spring 612 is installed between the foot pedal 611 and the right side seat 68.

[0024] Through the above structure, the mounting hole 63 opened on the mounting seat 62 can be used to insert bolts into the mounting hole 63 to screw the entire brake mechanism 6 on the chassis of the transport vehicle, providing a supporting point for the entire brake mechanism 6.

[0025] In this embodiment, the tire 4 is a solid belly explosion-proof tire and an anti-skid groove 5 is provided on the tire 4 .

[0026] Through the above structure, the tire 4 is set as a solid-belly explosion-proof tire, so that the tire 4 has high load-bearing and explosion-proof performance. At the same time, the anti-skid grooves 5 arranged on the tire 4 make the tire 4 have good anti-skid performance.

[0027] In this embodiment, the annular disk 61 is sleeved on the outer side of the axle rod 1 of the transport vehicle, and the inner diameter of the annular disk 61 is larger than the outer diameter of the axle rod 1 of the transport vehicle.

[0028] With the above structure, the inner diameter of the ring disk 61 is larger than the outer diameter of the transport vehicle axle rod 1, so the inner wall of the ring disk 61 does not contact the transport vehicle axle rod 1, thereby avoiding interference of the ring disk 61 when the transport vehicle axle rod 1 rotates.

[0029] In this embodiment, the brake seat 66 and the brake pad 67 are both L-shaped in cross section.

[0030] Through the above structure, the brake pad 67 is set in an L-shaped structural cross-section, which effectively increases the friction area between the brake pad 67 and the wheel hub 3, making braking more stable.

[0031] In this embodiment, the return spring 612 is sleeved on the outer side of the second hydraulic rod 69 and the inner side of the return spring 612 does not contact the outer side of the second hydraulic rod 69 .

[0032] Through the above structure, the rebound force of the return spring 612 causes the foot pedal 611 to have an upward movement tendency. When no pressure is applied to the foot pedal 611, the foot pedal 611 can automatically complete the return under the rebound force of the return spring 612.

[0033] In this embodiment, the foot pedal 611 is provided with anti-slip convex teeth.

[0034] Through the above structure, the anti-skid protruding teeth on the foot pedal 611 increase the surface roughness of the foot pedal 611, making it difficult for the foot to slide when stepping on the foot pedal 611.

[0035] In the utility model, when using the transport truck to transport goods, braking operation can be performed during use. The foot steps on the foot pedal 611, and the foot pedal 611 drives the second hydraulic rod 69 to descend. When the second hydraulic rod 69 retracts, the hydraulic oil inside its working chamber is transported to the oil chamber inside the first hydraulic rod 65 through the hydraulic oil pipe 610. Then, the output end of the first hydraulic rod 65 drives the brake seat 66 and the brake pad 67 installed on the side to abut against the wheel hub 3. Under the action of the brake pad 67, a braking friction force is generated on the wheel hub 3. When the foot pedal 611 is released, the rebound force of the return spring 612 will lift the foot pedal 611, and then the brake pad 67 will retract away from the wheel hub 3. At this time, the wheel hub 3 loses the braking friction, and the braking effect is released.

[0036] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
