Description
Technical field
The utility model relates to a kind of shock attenuation device, and more particularly, particularly a kind of shaft bottom suspension type shock attenuation device, belongs to pit gear technical field.
Background technology
The installation of down-hole buffer-braking equipment is mainly divided into two kinds of situations: one is lower wall braking, is directly installed on by shock absorber on which floor girder steel of more than collision prevention girders.Two is the brakings of upper dish, is arranged on by shock absorber on the girder steel near main shaft loading equipment mouth or bottom and shaft joint of the auxiliary shafts.
In new design mine, install girder steel and design and installation in advance put in place, if mine main, installation site does not have girder steel, then adopt anchor pole support or draw the pattern increase girder steel of hitch.But in a lot of mine main, because downhole environment is severe, trickle is very large, and the factors such as shaft deformation, cause increasing girder steel.
And general pit shaft ingate auxiliary shaft all has metal underwork, and intensity is very large, if the bottom girder of metal underwork can be utilized to install shock absorber, can realize installing.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel shaft bottom suspension type shock attenuation device, to overcome described defect of the prior art.
Utility model content
For solving the problem, the purpose of this utility model is to provide a kind of structure simple, easy for installation and the shaft bottom suspension type shock attenuation device that cushion characteristic is good.
In order to solve problem set forth above, the technical solution adopted in the utility model is: a kind of shaft bottom suspension type shock attenuation device, it is located at the top of collision prevention girders, for cushioning lifting container, described shaft bottom suspension type shock attenuation device comprises buffering transverse beam, traction steel band, lower bend, upper bend, sleeve column, traveller, main steel band and pressure roller group, described buffering transverse beam is located at the below of lifting container, and described traction steel band one end connects buffering transverse beam, and the other end connects traveller; Described upper bend and lower bend are installed on the upper side and lower side of sleeve column respectively; Described traveller matches with sleeve column, and can move up and down along sleeve column; One end of described main steel band is connected on buffering transverse beam; Described pressure roller group is arranged on traveller, and described upper bend can be connected in pressure roller group, clamps main steel band to make described pressure roller group.
According to a preferred embodiment of the present utility model: also comprise the strut member for supporting described sleeve column.
According to a preferred embodiment of the present utility model: the end of described traction steel band is connected with traveller by a traction bearing pin, and lower bend can be connected on traction bearing pin, departs from traveller to make traction bearing pin.
Compared with prior art, the beneficial effects of the utility model are: shaft bottom of the present utility model suspension type shock attenuation device has the plurality of advantages such as structure is simple, easy for installation, cushion characteristic is good.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1 and Fig. 2, a kind of shaft bottom suspension type shock attenuation device that the utility model provides, it is located at the top of collision prevention girders 11, for cushioning lifting container 1, this shaft bottom suspension type shock attenuation device comprises buffering transverse beam 2, traction steel band 3, strut member 4, lower bend 5, upper bend 6, sleeve column 7, traveller 8, main steel band 9, pressure roller group 10 and traction bearing pin 12.
Wherein, described buffering transverse beam 2 is located at the below of lifting container 1, described traction steel band 3 one end connects buffering transverse beam 2, the other end connects traveller 8, specifically: the end of traction steel band 3 is connected with traveller 8 by traction bearing pin 12, and lower bend 5 can be connected on traction bearing pin 12, departs from traveller 8 to make traction bearing pin 12.
Described upper bend 6 and lower bend 5 are installed on the upper side and lower side of sleeve column 7 respectively.
Described traveller 8 matches with sleeve column 7, and can move up and down along sleeve column 7; One end of described main steel band 9 is connected on buffering transverse beam 2; Described pressure roller group 10 is arranged on traveller 8, and described upper bend 6 can be connected in pressure roller group 10, to make described pressure roller group 10 clamp main steel band 9, and then realizes the function of buffering.
Described strut member 4 is for supporting sleeve column 7.
The principle of design of shaft bottom of the present utility model suspension type shock attenuation device is as follows: because shock attenuation device of the present utility model is located at the top of collision prevention girders 11, and distance H between its installation site and collision prevention girders 11 is far away, and active braking distance h only 4 ~ 6 meters, and the action initial point of shock attenuation device can realize according to the length of actual conditions adjustment suspension steel band.When after lifting container 1 pulleying, lifting container 1 continues walking collision buffering crossbeam 2 downwards by shock attenuation device, and buffering transverse beam 2, by drawing the traction of steel band 3 and main steel band 9, drives traveller 8 to walk downwards, by the effect of upper bend 6 pairs of pressure roller groups 10, realize the progressively loading of main steel band 9; After traveller 8 runs to the bottommost of sleeve column 7, completed and progressively loaded, traveller 8 no longer continues walking downwards.Now, the traction bearing pin 12 be connected with traction steel band 3 departs from traveller 8 under the effect on the inclined-plane of lower bend 5, and the lifting container 1 of downward pulleying is continued run downwards and realize buffering with main steel band 9 by collision prevention girders 11.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
