[0001] The present invention relates to the technical field of thrust trolleys, and particularly to a new type of unpowered assisted thrust trolley. Background Art

[0002] In the technical field of thrust trolleys, the thrust trolley not only realizes the function of pushing the item to be pushed, but also should have high reliability and high safety to prevent safety problems caused by untimely work. Therefore, higher requirements are imposed on the adaptability and reliability of the thrust trolley and the product.

[0003] At the present stage, the working modes of hydraulic drive or electric drive are generally selected. Such working modes of oil cylinders and electric drives occupy a large space and have the risks of oil leakage and electric control failures, and the reliability is relatively low. When the thrust trolley is applied to the fields of aerospace high-speed movement to assist object transfer and transportation, due to the high reliability requirements and narrow working space, the existing structures are difficult to achieve.

[0004] Therefore, it is necessary to provide a new type of unpowered assisted thrust trolley to solve the above problems. Summary of the Invention

[0005] The present invention provides a new type of unpowered assisted thrust trolley to solve the existing problems.

[0006] The new type of unpowered assisted thrust trolley of the present invention adopts the following technical solutions, including: A vehicle body, on which rollers are provided, and an installation through groove is vertically opened in the middle thereof; A locking assembly, which includes: A locking plate, the middle of which is rotatably connected in the installation through groove, and one side of the top thereof is a locking portion; A guiding cylinder, one end of which is closed and hinged to the bottom of the vehicle body, and a movable rod is slidably connected inside the other end thereof, and one end of the movable rod extending out of the guiding cylinder is hinged to the lower part of the locking plate; And a reset assembly, which is arranged between the closed end of the guiding cylinder and the end of the movable rod; Wherein, the locking portion and the guiding cylinder are located on the same side of the locking plate.

[0007] Preferably, an arc-shaped sliding groove is opened on the locking plate centered on the rotation center of the locking plate, a horizontally arranged guiding and limiting rod is inserted into the arc-shaped sliding groove, and the end of the guiding and limiting rod is connected to the inner wall of the installation through groove.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] An embodiment of a new type of unpowered auxiliary thrust trolley of the present invention. In this embodiment, the thrust trolley is applied to the field of aerospace high-speed movement to assist in object transfer and transportation, that is, driven by a power source to drive the thrust trolley, so that the roller 10 of the thrust trolley slides on a smooth slide rail, thereby achieving the purpose of transferring an object. The trolley has a relatively high movement speed during movement, and the contact surface with the slide rail is relatively smooth, with less resistance, and can transfer objects quickly. Specifically, Figure 1 、 Figure 2 and Figure 8 As shown in, it includes: a vehicle body 1 and a locking component. The vehicle body 1 is provided with rollers 10. As Figure 6 shown, an installation through groove is vertically opened in the middle of the vehicle body 1; the locking component includes: a locking plate 4, a guide cylinder 7 and a reset component. The middle of the locking plate 4 is rotatably connected in the installation through groove, and one side of the top of the locking plate 4 is a locking part; one end of the guide cylinder 7 is closed and hinged to the bottom of the vehicle body 1, and a moving rod 8 is slidably connected inside the other end of the guide cylinder 7. The end of the moving rod 8 extending out of the guide cylinder 7 is hinged to the lower part of the locking plate 4; the reset component is arranged between the closed end of the guide cylinder 7 and the end of the moving rod 8. Among them, the locking part and the guide cylinder 7 are located on the same side of the locking plate 4.

[0021] In one embodiment, as Figure 1 and Figure 7As shown, an arc-shaped sliding groove is formed in the locking plate 4 centered on the rotation center of the locking plate 4. A horizontally arranged guiding and limiting rod 3 is inserted into the arc-shaped sliding groove. The end of the guiding and limiting rod 3 is connected to the inner wall of the installation through groove. The locking plate 4 is rotatably connected in the installation through groove by a horizontally arranged rotating shaft 2.

[0022] In one embodiment, as Figure 2 shown, a wheel axle 5 is provided on the vehicle body 1, and a roller 10 is connected to the wheel axle 5 through a bearing.

[0023] In one embodiment, as Figure 2 and Figure 3 shown, a through groove is formed near the end of the vehicle body 1. The wheel axle 5 passes through the through groove of the vehicle body 1, and the wheel axle 5 located in the through groove is used to connect to a power source.

[0024] In one embodiment, as Figure 1 shown, a connecting ear is provided at the bottom of the vehicle body 1. Among them, a connecting rod is connected to the closed section of the guiding cylinder 7, and the other end of the connecting rod is hinged to the connecting ear through a first pin 6.

[0025] In one embodiment, a U-shaped groove with an opening facing downward is formed at the lower end of the locking plate 4. A second pin 9 is rotatably arranged in the U-shaped groove. Among them, one end of the movable rod 8 away from the guiding cylinder 7 is connected to the second pin 9.

[0026] In one embodiment, one end of the movable rod 8 located inside the guiding cylinder 7 is connected to a guiding sleeve. A space for accommodating a reset assembly is formed between the guiding sleeve and the guiding cylinder 7. The reset assembly includes a reset spring 11. One end of the reset spring 11 is connected to the guiding sleeve, and the other end of the reset spring 11 is connected to the closed end of the guiding cylinder 7.

[0027] Working principle During use, it should be noted that, as Figure 5 shown, the setting direction of the locking portion of the locking plate 4 is the same as the traveling direction of the trolley. As Figure 4 shown, the state during the installation process of the transported object is: push the object to move rightward along the Figure 4 indicated direction. When the front end of the object touches the locking plate 4, the locking plate 4 undergoes displacement under the action of force, changing from the Figure 1 state to the Figure 4 state. After the object exceeds a certain position, the locking plate 4 rotates around the rotating shaft 2 under the action of the bottom reset spring 11 and returns to the initial state. At this time, as Figure 5 shown, the locking portion at the top of the locking plate 4 just catches the corresponding position groove at the front end of the object, realizing the locking function. Finally, under the action of the power source, the object moves along with the trolley in the moving direction.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
