Technical field
The utility model relates to a kind of adjustable height supporting leg, is especially a kind ofly applicable to the device that in equipment use procedure, height of landing leg can regulate.
Background technology
Traveling type belt elevating conveyor is simple in structure, reliable, is widely used in work-site under coal mine, but traveling type belt elevating conveyor its height of landing leg of when work needs to regulate, to adapt to the installation of on-the-spot diverse location.Because the supporting leg of the traveling type belt elevating conveyor using at present does not have regulatory function, install inconvenient.
Utility model content
The purpose of this utility model is the deficiency overcoming in prior art, and a kind of simple in structure, safe and reliable, handled easily, adjustable height supporting leg applied widely are provided.
For achieving the above object, adjustable height supporting leg of the present utility model, comprise the square guide pipe being welded on middle frame, in square guide pipe, being set with can be at the unsteady supporting leg of square guiding inner telescoping tube, the bottom of described square guide pipe has a pair of fixed orifice of wearing, on described unsteady supporting leg, have a plurality of with to fasten set aperture one to wearing knock hole; Square guide pipe is provided with the locating dowel pin fixing with unsteady supporting leg, and described locating dowel pin is provided with short pin shaft and the axle of having strong market potential; Described unsteady supporting leg bottom is provided with the supporting leg base plate of two perk.
Described locating dowel pin one end is welded with bracelet; Described unsteady supporting leg top is provided with shrouding; Described unsteady supporting leg is that channel-section steel is made.
Beneficial effect: the utility model can be used for traveling type belt elevating conveyor and regulates in the course of the work height of landing leg, improves elevating conveyor work efficiency, reduces the working strength of operating personal.Major advantage has:
1. unsteady supporting leg and supporting leg base plate, shrouding are welding as one, and have changed the size of the working area of supporting leg base plate, can control the specific contact pressure floating between supporting leg and roadway floor, adapt to the requirement of heterogeneity roadway floor;
2. shrouding and bearing pin have limited unsteady supporting leg and have departed from from square guide pipe, in can avoiding using, lose;
3. short pin shaft, locating dowel pin, have strong market potential axle and bracelet assembly welding are integral, and are arranged in square guide pipe, once install, can not take out, and have avoided losing in equipment transportation and use procedure;
4. during the welding of bracelet and alignment pin, adopt arranged off-centre, center below, in use procedure, only in the situation that having External Force Acting, just may rotate, increased the reliability using;
5. supporting leg 5 prebored hole as required, meets the requirement of different adjustment height.

In figure: square guide pipe-1, short pin shaft-2, locating dowel pin-3, axle-4 of having strong market potential, float supporting leg-5, supporting leg base plate-6, bracelet-7, shrouding-8.
The specific embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is further described:
As shown in Figure 1, adjustable height supporting leg of the present utility model consists of square guide pipe 1, short pin shaft 2, alignment pin 3, the axle 4 of having strong market potential, the supporting leg 5 that floats, supporting leg base plate 6, bracelet 7, shrouding 8.Square guide pipe 1 is welded on middle frame 9, and in square guide pipe 1, being set with can be at the interior flexible unsteady supporting leg 5 of square guide pipe 1, and described unsteady supporting leg 5 is made for channel-section steel.The bottom of described square guide pipe 1 has a pair of fixed orifice of wearing, on described unsteady supporting leg 5, have a plurality of with to fasten set aperture one to wearing knock hole; Square guide pipe 1 is provided with the locating dowel pin 3 fixing with unsteady supporting leg 5, and locating dowel pin 3 one end are welded with bracelet 7, and supporting leg 5 tops of floating are provided with shrouding 8; Described locating dowel pin 3 is provided with short pin shaft 2 and the axle 4 of having strong market potential.
As Fig. 2 as shown in Figure 3, on square guide pipe 1 is circular hole and long slot bore to wearing fixed orifice one side, long slot bore is horizontal direction, respective side is concentric circle holes; Long slot bore size can meet short pin shaft 2 turnover, and the axle 4 of having strong market potential can not pass in and out requirement.
Shown in Fig. 4, short pin shaft 2, locating dowel pin 3, the axle 4 of having strong market potential are welded to form one with bracelet 7, the wherein eccentric welding of bracelet 7; On locating dowel pin 3, welding while having strong market potential axle 4, as shown in Figure 1, is assembled and is inserted after locating dowel pin 3 with unsteady supporting leg 5 at square guide pipe 1, at the interior welding of square guide pipe 1 axle 4 of having strong market potential.When manually bearing pin is taken out outward, short pin shaft 2 can move to square guide pipe 1 outside.When manually bearing pin is taken out outward, the axle 4 of having strong market potential cannot move to square guide pipe 1 outside.During bracelet 7 welding, bias is welded on the longitudinal plane of symmetry of bearing pin 3.
Fig. 5 shows, supporting leg 5 is integral with supporting leg base plate 6, shrouding 8 assembly weldings, can increase the area of contact with roadway floor, and shrouding 8 supporting leg that can prevent from floating after adjustable supporting leg assembling departs from adjustable supporting leg simultaneously.Described unsteady supporting leg 5 bottoms are provided with the supporting leg base plate 6 of two perk.Prebored hole as required on supporting leg 5, meets the requirement of different adjustment height, changes the size of the working area of supporting leg base plate 6, can control the specific contact pressure between supporting leg and roadway floor, adapts to the requirement of heterogeneity roadway floor.The hole of preboring differing heights on demand on supporting leg 5, manually bearing pin inserts in the hole of the supporting leg differing heights that floats, and can regulate the operating altitude of adjustable supporting leg.
Adjustable height of landing leg control process: rotation bracelet 7 is vertical with square guide pipe 1, outwards extracts alignment pin 3 to the horizontal long slot bore of short pin shaft 2 on square guide pipe 1 out and goes out from square guide pipe 1; Raise or reduce the supporting leg that floats to needs height and position; Handle manual bearing pin and be inserted into bearing pin 4 contact supporting legs 5 to square guide pipe 1; Rotation manual bearing pin makes bracelet 7 directed towards ground, and bearing pin 2 becomes plumbness with horizontal long slot bore on square guide pipe 1, and height adjusting work completes.
