Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of colliery rack pinion overload hydraulic rotation platform, realize the transport of hydraulic support in coal-face, 90 degree turn to and put the operations such as in place; This equipment can reduce the labour intensity of workman, increases work efficiency and safety.
To achieve these goals, the technical solution adopted in the utility model is: a kind of colliery rack pinion overload hydraulic rotation platform, comprise hydraulic cylinder, load platform, the head that is in transmission connection, tooth bar auxiliary fixing member, platform base, gear wheel and driving rack, load platform is arranged on platform base, between load platform and platform base, gear wheel is installed, load platform is connected with gear wheel key
Hydraulic cylinder is fastenedly connected by be in transmission connection head and driving rack; Gear wheel and driving rack form rack pinion; Tooth bar auxiliary fixing member installation site at driving rack leading portion, with ground static connection.
The piston rod of hydraulic cylinder be in transmission connection between head as being threaded; Be in transmission connection between head with driving rack as bolt is connected.
Platform base is connected with ground by bolt, and there is cylinder boss center, has two pairs of rib supplemental support; Boss center is provided with bearing outer ring installing space.
Tooth bar auxiliary fixing member comprises a pair roller, roller and driving rack back contact.
There are three grades of boss cylinders load platform lower surface, first order boss cylinder has corresponding key and gear wheel keyway coordinate to form key to be connected; The second level and third level boss cylinder coordinate with the inner ring of bearing respectively.
The utility model has the following advantages compared with the prior art:
1, the price of general hydraulic support truck is general higher, and middle and small scale coal mine is difficult to burden.And this platform structure is simple and clear, components and parts advantage of lower cost, for comparatively economical general middle and small scale coal mine, can be promoted at short notice.
2, the working stability of whole platform is contributed to using hydraulic cylinder as power source.The work safety of hydraulic cylinder is higher and hydraulic cylinder can provide larger input power, can drive larger load.
3, the roller at tooth bar auxiliary fixing member back contributes to the job stability improving driving rack, prevents rack work position that obviously skew occurs.
4, this platform can realize the rotation of hydraulic support easily, coordinates other corollary apparatus easily can realize movement and the placement of hydraulic support.

Detailed description of the invention
Below in conjunction with accompanying drawing 1, the utility model is described in further detail.
As shown in figures 1-8, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As shown in figures 1 and 3, colliery rack pinion overload hydraulic rotation platform comprise hydraulic cylinder 1, load platform 2, be in transmission connection 3, tooth bar auxiliary fixing member 4, platform base 5, gear wheel 6, driving rack 7.
Load platform 2 is arranged on platform base 5, is provided with gear wheel 6 between load platform 2 and platform base 5, and load platform 2 is connected with gear wheel 6 key,
Hydraulic cylinder 13 to be fastenedly connected with driving rack 7 by being in transmission connection; Gear wheel 6 and driving rack 7 form rack pinion; Tooth bar auxiliary fixing member 4 installation site at driving rack 7 leading portion, with ground static connection.
Hydraulic cylinder 1 and ground are connected by bolt, its piston rod be in transmission connection between 3 as being threaded; Be in transmission connection between 3 with driving rack 7 as bolt is connected; Hydraulic cylinder 1 is as motive power, the 3 drive driving rack 7 that are in transmission connection that move through of piston rod do rectilinear motion, tooth bar auxiliary fixing member 4 comprises a pair roller 8, roller 8 and driving rack 7 back contact, and contact position is positioned at tooth bar 7 away from being in transmission connection 3 sections.Tooth bar is when rectilinear motion, and tooth bar auxiliary fixing member 4 effectively can provide active force, prevents driving rack 7 from offseting.Tooth bar auxiliary fixing member is connected by bolt and ground self.
As shown in Figure 6 and Figure 7, platform base 5 is connected with ground by bolt, and there is cylinder boss 9 center, has two pairs of rib 10 supplemental support; Boss 9 center is provided with bearing outer ring installing space.There are three grades of boss cylinders 12 load platform lower surface, first order boss cylinder has corresponding key 11 and gear wheel 6 keyway coordinate to form key to be connected; The second level and third level boss cylinder coordinate with the inner ring of bearing respectively.Load platform 2 to be contacted with gear wheel 6 by key and installs, then is arranged on platform base 5 by bearing, realizes the rotation being driven load platform 2 by the circular motion of gear wheel 6.And as previously mentioned, driving rack 7 engages with gear wheel under the drive of hydraulic cylinder, thus realize rack pinion.
