Specific embodiments
[0011] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0012] Please refer to Figure 1-2 , the present utility model provides a technical solution: a large-stroke jacking device implemented in a narrow space, including a frame body 1, a bracket is provided on the frame body 1, a large-stroke cylinder 2 is installed on the bracket, a first slide rail 3 is provided on the frame body 1 and in front of the telescopic end of the large-stroke cylinder 2, a first rack 4 is installed on the moving end of the first slide rail 3, brackets 5 are installed on both sides of the first slide rail 3 on the frame body 1, circular through holes corresponding to each other in position are opened on the brackets 5, bushings 6 are inserted into the circular through holes, a first gear 7 and a second gear 8 are respectively sleeved at both ends of the bushing 6, the first gear 7 meshes with the first rack 4, a support frame 9 is provided on the frame body 1 and on one side of the second gear 8, a vertical second slide rail 10 is provided on the support frame 9, a second rack 11 is installed on the moving end of the second slide rail 10, the second rack 11 meshes with the second gear 8, and a jacking rod 12 is provided on the second rack 11.
[0013] As a preferred technical solution, further, appliance leg positioning columns 13 are installed on the frame body 1 and near the four corners.
[0014] As a preferred technical solution, further, a positioning fork frame 14 is provided on the jacking rod 12.
[0015] It should be noted that: in a narrow space where the height of the logistics appliance from the ground is small, the lifting action in the height direction is realized by using the first gear 7, the second gear 8, the first rack 4, the second rack 11, and the large-stroke cylinder 2. The tower pulley is made by installing two parallel gears on the same shaft, which can ensure that the walking trajectories of the two racks do not interfere with each other. When the large-stroke cylinder 2 extends, the first rack 4 drives the first gear 7 and the second gear 8, and transmits kinetic energy to the second rack 11, thereby raising the jacking rod and playing a jacking role.
[0016] It should be noted that: after the AGV automatically places the finished appliance in position, due to the limited height of the finished appliance from the ground, it is impossible to implement the lifting scheme inside the cylinder with a cylinder having a large stroke in a limited space. Especially in the case where a large jacking distance and jacking force are required, a cylinder with a larger stroke is needed. The application of a large-stroke cylinder combined with a sheave and a rack in such a narrow space can achieve a movement in an axial direction different from the axial direction of the cylinder extension, and can realize the function of jacking the internal mechanism of the finished product logistics appliance. It can realize the automatic opening and closing of the limiting mechanism of the parts in the appliance.
[0017] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation. An element defined by the statement "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.
[0018] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
