Description

Technical Field

[0001] This utility model relates to the field of aerial ladder truck technology, specifically to a connecting mechanism and a working bucket for an aerial ladder truck. Background Technology

[0002] The work bucket of a ladder truck, as an important component of the truck, is responsible for transporting goods up and down. It consists of a base plate, front and rear baffles, left and right baffles, and four corner baffles. Each baffle is mounted on a corresponding frame, and the frames are connected by hinges to facilitate the flattening or closing of the work bucket. Currently, ladder trucks generally use steel work buckets. The hinge joints of the outer frames of each component require welding multiple bushings, using locating pins to engage with these bushings to achieve hinges at different positions. This increases the welding workload, makes it difficult to ensure coaxiality, and increases assembly difficulty.

[0003] In addition, due to the need to lay and fix the base plate or baffle, it is necessary to make the support components separately and then weld the support components to the corresponding frame. This not only increases the overall workload, but also makes it difficult to ensure the flatness of the base plate or baffle. Utility Model Content

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. The terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model.

[0020] Example 1 like Figures 1 to 2 As shown, this utility model discloses a connecting mechanism for a ladder truck work bucket, including an integral support body 1, a sleeve 3 and a positioning block 4 made of profile. The sleeve 3 and the positioning block 4 are located on one side of the support body 1, and the sleeve 3 is located above the positioning block 4. Multiple sleeves 3 are spaced apart along the length direction of the support body 1. The sleeves 3 can be processed in corresponding positions and quantities according to actual use to meet the usage requirements in different scenarios. The positioning block 4 extends along the length direction of the support body 1.

[0021] In this embodiment, the connecting mechanism is welded and installed on the left and right sides of the bottom frame assembly 8.

[0022] Example 2 Reference Figures 3 to 7 As shown, unlike Embodiment 1, the other side of the support body 1 is also provided with a support plate 2. The support plate 2 has fixing holes 21, and multiple support plates 2 are spaced apart along the length of the support body 1. Positioning grooves 5 are provided between adjacent support plates 2. The positioning grooves 5 are used to quickly position the frame at the lower end of the base plate 11, improving installation efficiency and further ensuring the flatness of the base plate 11 during installation. Moreover, the multiple support plates 2 are spaced apart, which can be flexibly adapted to frames of different specifications, enhancing the versatility and flexibility of the connection mechanism.

[0023] Furthermore, the support body 1, the support plate 2, the sleeve 3, and the positioning block 4 are an integral structure, and all are made of aluminum alloy. This integral structure design reduces welding processes, avoiding stress concentration and deformation problems caused by welding, thereby improving the stability and service life of the entire connection mechanism. The choice of aluminum alloy not only reduces the weight of the connection mechanism, meeting the lightweight design requirements of the aerial ladder truck, but also makes it easy to process and form, reducing production costs and improving production efficiency.

[0024] In this embodiment, both the support body 1 and the positioning block 4 are provided with weight-reduction grooves 6. While ensuring the structural strength of the support body 1 and the positioning block 4, the weight of the connecting mechanism is effectively reduced, which is conducive to the lightweight design of the ladder truck's work platform.

[0025] Furthermore, the cross-section of the weight-reducing groove 6 is rectangular or circular. The diverse shapes and structures of the weight-reducing groove 6 allow the connecting mechanism to better adapt to different models and usage scenarios of aerial ladder trucks, further improving its versatility and practicality, while also simplifying processing and reducing manufacturing costs.

[0026] In this embodiment, the support 1 and the positioning block 4 are generally L-shaped. This allows the connecting mechanism to fit and be fixed better when connected to other components of the ladder truck, enhancing the stability of the connection.

[0027] Furthermore, a weight-reducing groove 7 is provided between the sleeve 3 and the positioning block 4, which further reduces the weight of the connecting mechanism.

[0028] In practical use, the front frame assembly 10 and the rear frame assembly 9 adopt the connection mechanism without the support plate 2 in Embodiment 1. In this embodiment, the connection mechanism is welded and installed on the front and rear sides of the bottom frame assembly 8. The bottom frame assembly 8 is connected to the adjacent front frame assembly 10 and rear frame assembly 9 through the sleeve 3 and the pin shaft. The support plate 2 is used to support the bottom plate 11. The screws or bolts pass through the bottom plate 11 and the end of the positioning hole 21 and are fitted with nuts, thereby supporting and fixing the bottom plate 11 and ensuring the firmness and flatness of the bottom plate 11 installation. Taking the rear frame assembly 9 as an example, the bottom frame assembly 8 and the rear frame assembly 9 are made of aluminum alloy. The sleeves 3 of the two connecting mechanisms on the bottom frame assembly 8 and the rear frame assembly 9 are staggered. Through the cooperation of the sleeves 3 and the pins, the bottom frame assembly 8 and the rear frame assembly 9 are hinged. After the bottom frame assembly 8 and the rear frame assembly 9 are unfolded, the positioning blocks 4 of the adjacent connecting mechanisms contact each other, limiting the unfolding angle and ensuring the flatness of the base plate 11. Compared with the traditional method of welding multiple bushings, this connecting mechanism greatly reduces the amount of welding work and can better ensure the coaxiality of adjacent sleeves 3, improving the stability and safety of the ladder truck operation. Moreover, due to the use of an integrated connecting mechanism body, the overall structure is more stable, ensuring the overall structural strength.

[0029] Furthermore, refer to Figure 7 As shown, the positioning block 4 is provided with a positioning hole 41. After the front frame assembly 10 is retracted upwards, a positioning pin 12 is inserted into the front frame assembly 10. The lower end of the positioning pin 12 is installed on the positioning plate. The positioning plate is connected to the positioning hole 41 by screws or bolts to lock the front frame assembly 10 and keep it in a vertical state. This meets the connection requirements of different working states of the ladder truck's working bucket and further improves the convenience and versatility of use.

[0030] Example 3 like Figure 8 and Figure 9 As shown, the structure of the support plate 2 differs from that of Embodiment 1, but the rest is the same as that of Embodiment 1.

[0031] In this embodiment, the support plate 2 extends along the length of the support body 1. The support plate 2 provides a more continuous and stable support surface, further ensuring the flatness and stability of the baffle. Simultaneously, this extended support plate 2 structure facilitates baffle installation, enabling faster positioning and fixing of the baffle, thus improving installation efficiency. The structure of the extended support plate 2 and the support body 1 enhances the strength and rigidity of the entire connection mechanism, improving its service life and reliability.

[0032] In this embodiment, the connecting mechanism with the continuous support plate 2 is installed in the shorter part of the baffle in the working bucket of the ladder truck, such as the side beam 13 and the front side frame 14, to connect the two and support the baffle at the side beam 13 and the front side frame 14, ensuring the flatness of the baffle, meeting the connection requirements of different positions in the working bucket of the ladder truck, and improving the convenience of use.

[0033] This utility model also discloses a working bucket, including the connecting mechanism described above.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
