TECHNICAL FIELD
[0001] The utility model relates to concrete slab transportation technical field especially relates to a concrete slab transport vehicle. BACKGROUND
[0002] In the engineering site construction process, building materials such as concrete slab need to be transferred between different positions. In order to improve the transportation efficiency, reduce the labor intensity and reduce the material damage, and at the same time to adapt to different terrains and road conditions of the engineering site, the concrete slab transport vehicle is often used to transport the concrete slab.
[0003] The existing concrete transport vehicle includes a bottom plate and a side plate, and at least two main wheels are arranged in the first direction perpendicular to the transportation direction below the bottom plate. The support rod is arranged on the two sides of the main wheel in the second direction parallel to the transportation direction, and the bottom of the support rod is higher than the bottom of the main wheel. In the process of transporting the transport vehicle loaded with the concrete slab, the bottom plate is kept horizontal by relying on manpower. When the concrete transport vehicle needs to be temporarily parked, the bottom plate is inclined downward by a preset angle by relying on the support of the main wheel and the side support rod in the case of no manpower support, so as to realize parking and avoid that the inclined angle of the bottom plate is too large to cause the concrete slab to slide off. At the same time, since the bottom plate can be inclined downward by a certain angle, the loading and unloading of the concrete slab are facilitated.
[0004] When the transport personnel change the transport vehicle from the transportation state to the parking state, the usual operation is that: the transport vehicle moves forward by relying on its own inertia at the same time, the transport personnel continuously incline the bottom plate downward from the horizontal state, when the transport vehicle stops moving, the support rod just contacts the ground,
[0005] The existing transport vehicle has the problem that due to the mistake of the operator, the support rod contacts the ground in advance before the transport vehicle continues to move forward by relying on inertia and stops. Since the friction between the support rod and the ground is large, the transport vehicle stops moving at the moment when the support rod contacts the ground, and the carried concrete slab continues to keep the trend of moving forward due to inertia, which causes the concrete slab to fall off from the transport vehicle, causes the concrete slab to break at the same time, and threatens the personal safety of the surrounding personnel, so there is a safety hazard.

DETAILED DESCRIPTION
[0026] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, in order to facilitate the description, only the parts related to the present application are shown in the drawings, and not all the structures. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0027] The terms "comprising" and "having" and any variations thereof in the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.
[0028] In this paper, the phrase "embodiment" means that the specific features, structures or characteristics described in conjunction with the embodiment can be included in at least one embodiment of the present application. The phrase appears at various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment independent of or alternative to other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0029] As Figure 1 and Figure 2 shown, the concrete slab transport vehicle 100 of the utility model comprises a frame 1, a plurality of main wheels 2 and a plurality of support assemblies 3. The frame 1 comprises a bottom plate 11 and at least one side plate 12. The bottom plate 11 and the side plate 12 are connected to each other and form a preset included angle. In an embodiment, as Figure 1 shown, the side plate 12 is perpendicular to the bottom plate 11. The bottom plate 11 and the side plate 12 form a placing space for placing the concrete slab. The plurality of main wheels 2 for forming rolling connection with the ground when the concrete slab transport vehicle 100 moves are sequentially arranged below the bottom plate 11 along a first direction. The plurality of support assemblies 3 are arranged on both sides of the bottom plate 11 in a second direction perpendicular to the first direction. Each support assembly 3 comprises a connecting body 31 connected to the bottom plate 11 and a sub-wheel 32 fixed on the connecting body 31, and the bottom of the sub-wheel 32 is higher than the bottom of the main wheel 2.
[0030] When the transport personnel push the concrete slab forward by hand and need to stop, the operator stops applying forward pushing force to the concrete slab transport vehicle 100, the concrete slab transport vehicle 100 continues to move forward by inertia at the same time, the transport personnel gradually releases the hand, the bottom plate 11 starts to change from the horizontal state during transportation to the downward inclined state, and if the support assembly 3 is in contact with the ground before the concrete slab transport vehicle 100 completely stops moving, the main wheel 2 and the sub-wheel 32 simultaneously form rolling connection with the ground, the concrete slab transport vehicle 100 and the concrete slab carried thereby continue to move forward by inertia until completely stop. By installing the sub-wheel 32 on the support assembly 3, the support assembly 3 is prevented from being in contact with the ground before the concrete slab transport vehicle 100 moves forward by inertia and completely stops, which causes the concrete slab transport vehicle 100 to suddenly stop and the concrete slab carried by the concrete slab transport vehicle 100 to continue to move forward by inertia, resulting in the concrete slab falling from the concrete slab transport vehicle 100 and causing damage to surrounding personnel, thereby improving the safety of the concrete slab transport vehicle 100 during use.
[0031] It should be noted that the purpose of the bottom of the sub-wheel 32 of the concrete slab transport vehicle 100 of the utility model being higher than the bottom of the main wheel 2 is that when the concrete slab is transported to the target position and unloaded, the bottom plate 11 is in the downward inclined state under the support of the sub-wheel 32 and the main wheel 2, thereby facilitating unloading of the concrete slab.
[0032] In an embodiment of the concrete slab transport vehicle 100 of the utility model, the structure of the connecting body 31 is shown in Figure 1The connector 31 includes a first rod body 311 connected with the bottom plate 11 and a second rod body 312 connected with the auxiliary wheel 32, and a rotating connection part 313 arranged between the first rod body 311 and the second rod body 312. The rotating connection part 313 is used to adjust and fix the angle of the first rod body 311 relative to the second rod body 312. Specifically, when the length of the transported concrete slab is relatively long, the second rod body 312 is rotated to move the auxiliary wheel 32 downward, so as to avoid that the concrete slab is damaged due to the fact that the concrete slab is in contact with the ground before the auxiliary wheel 32 is in contact with the ground when the concrete slab transport vehicle 100 is parked.
[0033] There are various ways to connect the side plate 12 and the bottom plate 11. In one embodiment, the side plate 12 and the bottom plate 11 are fixedly connected by welding. In another embodiment, please refer to Figure 2 As shown, the side plate 12 can rotate relative to the bottom plate 11 in the first direction, and the concrete slab transport vehicle 100 further includes a fixing part 4 used to fix the angle between the bottom plate 11 and the side plate 12. By rotating the side plate 12 and fixing the angle between the side plate 12 and the bottom plate 11, the placement space of the concrete slab on the vehicle frame 1 is adjusted to adapt to the transportation of concrete slabs of different sizes and different quantities.
[0034] Specifically, the bottom plate 11 and the side plate 12 are connected by a first hinge 5. The fixing part 4 includes a support rod 41 connected with the bottom plate 11 by a second hinge 6 and a limiting part 42 arranged on the side plate 12, the support rod 41 abuts against the limiting part 42 to fix the angle between the side plate 12 and the bottom plate 11. In another embodiment, the limiting part 42 is arranged in a plurality of grooves on the side plate 12, and the support rod 41 is limited in the grooves and abuts against the side plate 12. In another embodiment, the limiting part 42 is a plurality of protrusions arranged on the side plate 12, and the support rod 41 abuts against the protrusions.
[0035] Specifically, in one embodiment, the end of the support rod 41 abutting against the side plate 12 is provided with a hook (not shown), and the limiting part 42 includes a ring (not shown) matched with the hook, so that the hook hooks the ring to connect the support rod 41 and the limiting part 42. This avoids the support rod 41 from falling off when connected with the limiting part 42, and enhances the reliability and safety of the concrete slab transport vehicle 100 in use.
[0036] In one embodiment, the bottom plate 11 is provided with a stopper 7 for stopping the concrete slab. When the concrete slab is placed horizontally, the concrete slab is located between the side plate 12 and the stopper 7. When the concrete slab is placed obliquely, one end of the concrete slab stops against the side plate 12 and the other end stops against the stopper 7. By providing the stopper 7, the concrete slab transport vehicle 100 can select a suitable placement mode of the concrete slab on the frame 1 according to the size and quantity of different concrete slabs, thereby enhancing the applicability of the concrete slab transport vehicle 100.
[0037] When it is necessary to transport the concrete slab to a high-rise building, the transport vehicle carrying the concrete slab needs to be placed on a construction elevator, and the construction elevator has a rated load. Therefore, in one embodiment, the bottom plate 11 and the side plate 12 are both hollow structures, so as to reduce the weight of the concrete slab transport vehicle 100, so that the concrete slab transport vehicle 100 of the utility model can transport more concrete slabs in the same transport, thereby improving the construction efficiency.
[0038] In one embodiment, the main wheel 2 and the auxiliary wheel 32 are both rubber wheels, which reduces the vibration of the concrete slab transport vehicle 100 when moving on uneven road surfaces.
[0039] The above embodiments only express several embodiments of the utility model, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the utility model, several modifications and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
