Description

Technical Field

[0001] This utility model relates to the field of construction engineering transportation technology, and in particular to a flatbed trolley with limiting and locking functions. Background Technology

[0002] Flatbed trucks, also known as construction machinery transport vehicles, flatbed trucks, or low-bed trucks, are mainly used to transport non-detachable objects such as excavators, loaders, and harvesters. Flatbed trucks are common large heavy-duty trucks in daily life. These vehicles are widely used in factories, construction sites, and other large-scale production or engineering sites. The strong load-bearing capacity of flatbed trucks has made them play an important role in economic development.

[0003] Flatbed trolleys, as a common transportation tool, play a vital role on construction sites. However, existing flatbed trolleys lack limiting and locking devices on the load-bearing surface, posing a risk of cargo tipping over due to uneven road surfaces. This can result in economic losses, especially when transporting items like floor tiles or glass. Current technologies typically use straps to secure the cargo. For example, US Patent 20070048103A1 discloses an automated system that can secure cargo to a flatbed trolley. This system automatically tightens the straps to secure the trailer's load. An electric motor is attached to each end of the drive shaft and used to rotate it. The straps untie around the drive shaft, stretch over the load, and connect to the other side of the trailer to initiate the load securing process. Then, the motor is engaged to rotate the drive shaft and automatically tighten the straps, thus completing the fixing process. However, in actual use, the flatbed trolleys transport goods of varying sizes. When faced with long or short goods, the single and fixed straps cannot be used for binding, resulting in poor practicality. Meanwhile, Chinese utility model patent CN207496741U discloses a logistics trolley that facilitates the fixing of goods. This solution involves opening symmetrically arranged long strip grooves along the length of the inner walls on both sides of the frame. Sleeves are welded to the inner walls of the long strip grooves, and connecting plates are connected to the inner walls of the bottom ends of the sleeves by springs. The goods inside the frame are clamped and fixed by the two sets of connecting plates. However, this technical solution is not suitable for fixing irregularly shaped goods such as round glass. Utility Model Content

[0004] This utility model patent aims to address the shortcomings of the prior art by providing a flatbed trolley with limiting and locking functions, thereby solving the technical problems of cargo tipping and damage to carried items in the prior art due to the inability of flatbed trolleys to accommodate different body shapes and sizes.

[0006] Preferably, the limiting groove is arranged along the long side of the loading platform, and there are at least four sets of limiting grooves arranged in parallel to each other.

[0007] Preferably, the loading platform has a sliding groove on opposite sides, and a plurality of locking components are slidably connected in the sliding groove.

[0008] Preferably, the locking assembly includes a bolt that is embedded in and slides with a groove, and a tightening nut is threaded onto the bolt.

[0009] Preferably, the bolt is hollow and has an elastic rope fixedly connected inside.

[0010] Preferably, the loading platform has several latches slidably connected on the opposite side of the locking component to cooperate with the locking component.

[0011] Preferably, the bolt has an opening at the end furthest from the groove, and a small cover plate is detachably connected to the bolt opening.

[0012] Preferably, the baffle assembly includes a T-shaped baffle housing, the top of which has a cavity, into which a baffle can be inserted and connected.

[0013] Preferably, a contact plate is detachably connected to the top of the baffle, which is above the position of the baffle housing.

[0014] Preferably, shock-absorbing rubber is provided on the side of the contact plate away from the baffle.

[0015] The beneficial effects of this utility model are as follows: This utility model uses a sliding elastic rope to adjust the position of the elastic rope according to the different shapes of the goods, ensuring that the elastic rope is always in the center of the goods to guarantee the binding effect. At the same time, the baffle assembly and locking device work together to limit and fix irregular goods, further improving the stability of the goods and preventing the goods from tilting and breaking due to bumps.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1-3 As shown, a flatbed trolley with limiting and locking functions includes a loading platform 6 with grooves installed on the body of the flatbed trolley. The bottom wall of the loading platform 6 has several limiting grooves 3. A limiting device is detachably connected to the limiting groove 3. The limiting groove 3 is cross-shaped. Several wedge-shaped stakes 4 are fixed to the bottom wall of the limiting groove 3. The limiting device includes a baffle assembly 1. The bottom of the baffle assembly 1 is embedded in the limiting groove 3 and slides along the limiting groove 3. A wedge block 2 is provided on one side of the baffle assembly 1. The wedge block 2 cooperates with the wedge stakes 4 to fix the baffle assembly 1. In this embodiment, the loading platform 6 is installed on a conventional flatbed trolley. The loading platform 6 of this application can be installed on flatbed trolleys, flatbed wheelbarrows, flatbed transport vehicles and other transport vehicles.

[0027] The loading platform 6 has several limiting grooves 3 at the bottom of its inner wall. The limiting grooves 3 are cross-shaped with horizontal protrusions on both sides. Several wedge-shaped piles 4 are set on the bottom wall of the limiting grooves 3. The wedge-shaped piles 4 are preferably triangular.

[0028] When in use, the baffle assembly 1 is installed inside the limiting groove 3 to fix and limit the goods on the loading platform. Specifically, the square glass is placed into the loading platform 6 so that one side of the rectangular glass contacts the inner wall of the loading platform. The position of the baffle assembly 1 is adjusted according to the width of the glass. The baffle assembly 1 and the inner wall of the loading platform 6 cooperate to clamp and fix the square glass or goods.

[0029] The wedge block 2 is preferably triangular and forms a tenon and mortise structure with the wedge pile 4 to fix each other. In this application, the wedge block 2, which is manually disassembled and installed, is fixed with the wedge pile 4, which is fixed in the limiting groove 3 of the loading platform 6, to fix the tenon and mortise structure. This fixing method is more flexible. Compared with the traditional motor-driven clamping and fixing, there is no need to worry about fragile goods such as glass and ceramic tiles breaking due to excessive clamping by the motor drive.

[0030] Preferably, the limiting groove 3 is arranged along the long side of the loading platform 6, and there are at least four sets of limiting grooves 3 arranged in parallel to each other. In this embodiment, at least four sets of limiting grooves 3 are set on the bottom wall of the loading platform 6. With the help of the limiting device, the goods of different shapes can be fixed. When facing rectangular quadrilateral glass or box, multiple sets of limiting devices further improve the fixing efficiency through the tenon and mortise structure to prevent the goods from bumping and overturning during transportation.

[0031] When facing T-shaped or L-shaped polygonal glass or boxes, multiple sets of limiting devices can fix each side of the polygonal object respectively. In this embodiment, four sets are preferred. In actual use, limiting grooves and matching limiting components can be added as needed. At the same time, inclined through holes can be opened in the wedge-shaped pile 4, and a second limiting plate can be added in the limiting groove 3 in the opposite direction to the limiting device. The second limiting plate can cooperate with the limiting device to fix irregular goods more flexibly.

[0032] The multiple limiting devices in this embodiment also have a good fixing effect on round glass, mirrors, etc.

[0033] Preferably, the loading platform 6 has a sliding groove 13 on opposite sides, and a plurality of locking components 5 are slidably connected in the sliding groove 11 on the opposite sides of the loading platform. In this embodiment, the sliding groove 13 is provided on both sides of the outer side of the long side of the loading platform 6, and the locking components 5 are slidably connected in the sliding groove 13. The locking components slide horizontally along the sliding groove 13 and can be adjusted according to the position of the goods to ensure the best binding position and further improve the stability of the goods.

[0034] This solution also includes a second embodiment, in which the chute is set on the inner side of the long side of the loading platform 6, such as... Figure 5 As shown, installing the locking component 5 inside the loading platform 6 requires less elastic rope length during use and is also easier for staff to operate.

[0035] Preferably, the locking component 5 includes a bolt 14 that is embedded in and slides with the slide groove 13, and a tightening nut 141 is threaded onto the bolt 14. In this embodiment, the locking component 5 includes a bolt 14, which is embedded in the slide groove 13 and slides horizontally along the slide groove 13. At the same time, a tightening nut 141 is provided on the bolt 14 to fix the bolt 14.

[0036] Preferably, the bolt 14 is hollow and an elastic rope 8 is fixedly connected inside. In this embodiment, the bolt 14 is hollow and an elastic rope 8 is fixedly connected inside the bolt 14. When in use, the position of the bolt 14 is adjusted according to the volume of the cargo to ensure that the elastic rope 8 is located in the center of the cargo and to ensure the binding and fixing effect. After adjusting the position, the bolt 14 is fixed by tightening the nut 141 and the cargo is bound by the elastic rope 8.

[0037] Preferably, a plurality of latches 51 are slidably connected on the opposite side of the locking component 5 on the loading platform 6 to cooperate with the locking component 5. In use, the goods are bound together by stretching the elastic rope 8 and then fixed to the latches 51 on the opposite side. It should be noted that since the latches 51 are also slidably connected through the slide groove 13, different connection methods can be selected according to the length of the elastic rope. For example, when the goods are piled up too high and the elastic rope 8 is insufficient, the hooks 51 and bolts 14 can be aligned and connected in a straight line. When the goods are piled up in small quantities, a cross-binding method can be selected. In this embodiment, at least one set of locking components 5 and matching latches 51 is set in the slide groove 13, but the number of locking components 5 and latches 51 can be increased according to the weight of the goods. The locking component structure of this application is simple. It is fixed by sliding the bolt 14 and tightening the nut 141. Installation and disassembly are simple. Multiple sets of locking components 5 and matching latches 51 can be cross-connected and bound to each other, which is better and more flexible than traditional rope binding. Figure 7 As shown in this application, bolt 14 can be replaced with a cylindrical slider with an internal elastic rope 8, which works in conjunction with the tightening device in the prior art to achieve fixation.

[0038] Preferably, the bolt 14 is open at one end away from the slide groove 13, and a small cover plate 7 is detachably connected to the opening of the bolt 14. In this embodiment, the small cover plate 7 is used to store the elastic rope inside the bolt 14 when not in use, so as to prevent the elastic rope 8 from getting wet or damaged.

[0039] Preferably, the baffle assembly 1 includes a T-shaped baffle housing 11, the top of which has a cavity. A baffle 12 can be inserted and connected into the cavity. In this embodiment, because the baffle assembly 1 is fixed by tenons and mortise and tenons, there will be gaps between the wedge piles 4, which may easily lead to instability when the wedge piles 4 and wedge blocks 2 are fixed together. Therefore, a baffle 12 is detachably connected to the baffle housing 11. In this embodiment, a hollow baffle housing 11 is selected, and the baffle 12 is detachably connected by inserting it into the cavity. In use, other more robust connection methods can be replaced. The baffle 12 can be increased or selected according to the height of the goods stacking. In use, the baffle 12 is higher than the height of the goods stacking to ensure complete fixation.

[0040] Preferably, a contact plate 121 is detachably connected to the top of the baffle 12 above the baffle housing 11. In this embodiment, to solve the problem of gaps between the wedge piles 4, a contact plate 121 is detachably added to the side of the baffle 12 that contacts the goods. The shape of the contact plate 121 can be adjusted according to different goods. The material of the contact plate 121 can be rubber or cork, etc. The contact plate 121 can be arc-shaped or toothed to further improve the friction between the contact plate 121 and the loaded goods. Especially for goods such as multi-layered overlapping glass tiles, the contact plate 121 can be designed as a loading platform with a multi-layered rack to further improve the safety of the goods during transportation.

[0041] Preferably, a shock-absorbing rubber 122 is provided on the side of the contact plate 121 away from the baffle 12. The shock-absorbing rubber is used to reduce damage to goods caused by bumps during transportation, and further improve the safety of fragile items such as glass tiles.

[0042] The specific working method of this application is as follows: First, the goods to be transported are placed inside the loading platform 6. According to the stacking height and shape of the goods, the baffle assembly 1 is installed and the position of the baffle assembly is adjusted. The baffle assembly 1 is then bound to each side of the goods. Specifically, when facing a rectangular quadrilateral glass or box, multiple sets of limiting devices are fixed to one side of the rectangular goods through a tenon and mortise structure to prevent the goods from bumping and overturning during transportation.

[0043] When facing T-shaped or L-shaped polygonal glass or boxes, multiple sets of limiting devices can fix each side of the polygonal object separately, ensuring that each protruding side of the polygonal goods is stably fixed.

[0044] When dealing with curved glass tiles or round packaged goods, the curved contact plate 121 can be used to clamp and fix the curved surface of the goods. After being fixed by the baffle assembly 1, it can be tied by the elastic rope of the locking assembly 5. Multiple locking assemblies and the matching buckles 51 can be tied together in a cross manner.

[0045] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
