A floating supporting leg capable of being telescopic in the square guide pipe is installed in the square guide pipe in a sleeved mode; a fixing through hole is formed in the lower portion of the square guide pipe, and a plurality of locating through holes which are coincident with the fixing through hole in diameter are formed in the floating supporting leg; the square guide pipe is provided with a locating pin fixed with the floating supporting leg, and a long pin shaft and a short pin shaft are arranged on the locating pin; a supporting leg base board with the two turnup ends is arranged at the bottom of the floating supporting leg. Holes with different heights are pre-drilled in the supporting leg according to needs, and the pin shafts are manually inserted into the holes, with the different heights, of the floating supporting leg, so that the working height of the supporting leg is adjusted.

Description

A kind of adjustable height supporting leg
Technical field
The present invention relates to a kind of adjustable height supporting leg, especially a kind ofly be applicable to the device that in the equipment use procedure, height of landing leg can be regulated.
Background technology
The 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 used does not at present have regulatory function, install inconvenient.
Summary of the invention
The objective of the invention is to overcome the deficiency in prior art, 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 invention, comprise the square guide pipe be 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 fixed 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 present invention can be used for the traveling type belt elevating conveyor and regulates in the course of the work height of landing leg, improves the 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 floated between supporting leg and roadway floor, adapt to the requirement of heterogeneity roadway floor;
2. shrouding and bearing pin have limited unsteady supporting leg from square guide pipe, breaking away from, and lose in can avoiding using;
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, in case install, namely 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 there is External Force Acting just may rotate, increased the reliability used;
5. supporting leg 5 prebored hole as required, meet the requirement of different adjustment height.

In figure: square guide pipe-1, short pin shaft-2, locating dowel pin-3, the axle of having strong market potential-4, float supporting leg-5, supporting leg base plate-6, bracelet-7, shrouding-8.
The specific embodiment
Below in conjunction with accompanying drawing, one embodiment of the present of invention are further described:
As shown in Figure 1, adjustable height supporting leg of the present invention 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 fixed with unsteady supporting leg 5, and locating dowel pin 3 one ends 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, and long slot bore is horizontal direction, and respective side is concentric circle holes; The 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 Figure 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; Welding is while having strong market potential axle 4 on locating dowel pin 3, as shown in Figure 1, and after locating dowel pin 3 is assembled and inserted to square guide pipe 1 with unsteady supporting leg 5, at the interior welding of square guide pipe 1 axle 4 of having strong market potential.When manually bearing pin was taken out outward, short pin shaft 2 can move to square guide pipe 1 outside.When manually bearing pin was 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 after adjustable supporting leg assembling floating breaks away 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, meet 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, the operating altitude that can regulate 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 the needs height and position; Handle manual bearing pin and be inserted into bearing pin 4 contact supporting legs 5 to square guide pipe 1; The rotation manual bearing pin makes bracelet 7 directed towards ground, and on bearing pin 2 and square guide pipe 1, horizontal long slot bore becomes plumbness, and height adjusting work completes.
