Description

TECHNICAL FIELD

[0001] The utility model relates to big article transportation equipment technical field especially relates to telescopic superlong big article transportation uses the expansion support. BACKGROUND

[0002] In the land transportation process of superlong big articles such as wind power equipment, extra-high voltage flat wave reactors, space warehouses and shield machines, in order to ensure the safety and stability of transportation, it is usually necessary to use a special support to reliably fix these articles on the transportation platform, such support not only needs to bear part of the weight of the articles, but also needs to effectively resist the bumps, vibrations and inertial forces generated during vehicle driving to prevent the displacement, overturning or deformation of the goods.

[0003] At present, the supports widely used in transportation practice are mostly simple in structure, and their telescopic adjustment function has obvious deficiencies. Most traditional supports use simple pin hole adjustment or manual bolt fastening method. When adjusting the length, the operator often needs to use additional tools for tedious disassembly and reassembly. The whole process is time-consuming and labor-intensive, and the adjustment efficiency is low. It is difficult to meet the operation needs of quickly adapting to articles of different sizes in the transportation site. In addition, the locking mechanism design of the existing support often has poor reliability. Common problems such as easy loosening after wear and tear of simple pins, self-rotation and back-off of bolts under continuous vibration, etc. lead to the gradual decay of locking force during long-distance transportation, which poses a serious safety hazard. On the other hand, the existing support has relatively single function and generally lacks effective auxiliary support and buffer mechanism. When carrying extremely long or unevenly distributed heavy goods, the cantilever section of the support is prone to excessive deformation due to concentrated load, which not only affects the supporting effect, but also may cause structural damage over a long period of use. At the same time, the rigid contact between the goods and the support also makes the impact vibration from the road directly transmitted to the goods itself, which poses a risk of internal damage to precision equipment or fragile materials.

[0004] Therefore, in view of the above problems of existing transportation support, such as tedious and time-consuming telescopic adjustment, easy loosening and instability of locking mechanism under vibration, and lack of effective auxiliary buffer function, which poses safety risk and efficiency bottleneck, a telescopic superlong big article transportation expansion support can be designed. Through screw transmission, labor-saving telescopic adjustment is realized, locking assembly ensures transportation anti-loosening, load-bearing column and rotating rod form stable triangular support, which has the advantages of quick adjustment, safe locking and high load-bearing capacity.

[0019] Wherein, base frame assembly 1 includes left and right side plates 101 and front and rear end plates 102, which are collectively enclosed into a rectangular frame structure, further comprising a reinforcing plate 103, the reinforcing plate 103 is fixedly connected to the lower end of the left and right side plates 101 and the front and rear end plates 102, and at least two groups of mounting seats 104 are provided on the outer side of the left and right side plates 101, the mounting seats 104 are installed on the lower end of the tail of the transport equipment by fasteners.

[0020] Meanwhile, the upper end of the bottom plate 201 and the lower end of the bearing platform 202 are fixedly connected with front and rear symmetrically distributed rotating seats 203, and the rotating seats 203 are located on the inside of the bottom plate 201 and the bearing platform 202, the rotating rod 204 is commonly connected between the two groups of rotating seats 203 corresponding to each other, the lower end of the outer side of the bearing platform 202 is fixedly connected with a U-shaped seat 205, the U-shaped seat 205 is rotatably connected with a bearing column 206, the lower end of the bearing column 206 successively penetrates the U-shaped seat 205 and the bottom plate 201, and the outer periphery is threadedly connected with a locking nut 207, the upper part of the bearing column 206 is fixedly connected with a limiting baffle 208, and the limiting baffle 208 is in close contact with the upper end surface of the bottom plate 201.

[0021] In addition, the transmission mechanism 3 includes a ball screw 301, a threaded sleeve 302 and a rocker 303, the ball screw 301 is rotatably connected to the inside of the base frame assembly 1, and one end penetrates the base frame assembly 1 and extends outward, the threaded sleeve 302 is threadedly connected to the outer periphery of the ball screw 301 and is fixedly connected with the expansion support component 2, and the rocker 303 is inserted into one end of the ball screw 301 extending outward.
