Abstract
The utility model relates to a column shoe, which comprises a column shoe main body. The profile of the top part of the column shoe main body takes a shape of trapezoid. The outer wall of the top part of the column shoe main body is uniformly provided with seven rib plates and a recovery lug. The top surface of the column shoe main body is provided with a circular groove. The column shoe has the advantages of processing the column shoe main body which is the main stressed component into an integrated component by injection molding, improving the stress structure of the column shoe main body, avoiding the problems of stress concentration and easy damage conventionally, effectively preventing a support from being inclined and reducing generation of accidents and also has the advantages of reasonable structure, uniform stress, good stability and capability of being recovered and recycled.
Description
Technical field
The utility model relates to a kind of coal mining work plane bracing or strutting arrangement accessory, relates in particular to a kind of post footwear.
Background technology
As everyone knows, mine underground work must adopt the support of face to protect frame; At present, coal mining work plane pillar adopts plank to do post footwear and cast iron post footwear more, also adopts the nylon steel to make the post footwear sometimes, and these conventional post footwear all have support function preferably, yet plank post footwear are difficult for recovery, and dismounting is wasted time and energy; Metal cast iron post footwear weight is big, and the workman is not easy to operate, needs many people can finish the supporting operation, and the support cost height is difficult for reclaiming, and dismounting is wasted time and energy, and especially is easy to corrosion under the environment of down-hole humidity, and repeat usage is low; Though nylon steel column footwear have overcome some deficiency of plank and cast iron post footwear, also there is the rigidity flexible not enough shortcoming of having a surplus, especially support male and female face, contact area is little, easily slide, can improve its anti-end performance of boring though add the diameter of huge pillar footwear, bring simultaneously and easily make pillar inclination, the weight of increase own, awkward defective.
The utility model content
The purpose of this utility model provides a kind of post footwear, is difficult for reclaiming to overcome existing post footwear, and repeat usage is low, and dismounting is wasted time and energy, support cost height, the deficiency of easy slip etc.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of post footwear comprise post footwear main body, and the section at described post footwear main body top is trapezoidal, evenly are distributed with seven gussets and a recovery ear on the outer wall at post footwear main body top, and the end face of post footwear main body is provided with circular groove.
The beneficial effects of the utility model are: stressed critical piece post footwear main body is injection molded into an integrated member, has improved its stress structure, avoided crossing destressing and concentrated flimsy problem, rational in infrastructure, stressed even, good stability, prevent that effectively pillar from tilting the generation of minimizing accident; Can recycle and reuse.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the front view of the described a kind of post footwear of the utility model embodiment;
Fig. 2 is the sectional view of the described a kind of post footwear of the utility model embodiment.
Among the figure:
1, post footwear main body; 2, gusset; 3, reclaim ear; 4, circular groove.
The specific embodiment
Shown in Fig. 1-2, the described a kind of post footwear of the utility model embodiment comprise post footwear main body 1, and the section at described post footwear main body 1 top is trapezoidal, be evenly distributed with seven gussets 2 and a recovery ear 3 on the outer wall at post footwear main body 1 top, the end face of post footwear main body 1 is provided with circular groove 4; Reclaim ear 3 and be connected, make post footwear main body 1 as a whole, when being convenient to withdrawing prop, simultaneously the post footwear are reclaimed together, can make the recycling of post footwear with 2 one-tenth in ear of recovery with wire rope or iron chains.
