Description

The invention relates to a mounting bracket for lifting loads.

Mounting brackets are an auxiliary work tool used for dismantling and assembling machines, equipment and equipment. They are used for lifting and transporting individual loads in the workplace and are valuable tools for assembly and repair personnel.

Mounting brackets are known, consisting of two supports fixedly connected by a crossbeam. A hoist or other hoist is provided on the cross member of the mounting bracket by means of which the load is lifted from the load-bearing location and can be transported by the mounting bracket.

In this mounting bracket, the supports and the cross beam have the task of carrying the load, while the hoist serves to lift the load.

The supports of the mounting bracket consist of two tubes of different diameter inserted into each other and provided with openings, so that by means of a pin inserted into the holes, the mounting bracket is adjustable in height.

The disadvantage of this mounting bracket is that the length of the stroke is reduced by the length of the chain block, so that the use of the mounting bracket in rooms with a careful free height between the load to be lifted and the ceiling is not possible.

198 381 the ββ practice in such cases raises the load, for example, to a provisional storage location, from where the winches are transported to the final positions by means of the inclined surface. Assembly personnel are required to exert a great deal of effort and often do not have the necessary safety at work · Furthermore, such a load movement is very time-consuming · In addition, it has proved to be disadvantageous in cost of dismantling and mounting the mounting bracket and adjusting it to a different ceiling height ·

SUMMARY OF THE INVENTION The object of the invention is to provide a mounting bracket which can be assembled and disassembled by simple means and low load and which can also be used in areas where there is little space between the load to be lifted and the ceiling.

According to the invention, this object has been achieved by a mounting bracket for lifting the mounting loads, consisting of abutments, at an acute angle and interconnected by a cross beam and arranged on the wheels. It is based on the fact that the supports are equipped with means for changing the angle at

According to a further feature of the invention, the angle changing means is formed by an engagement arm.

The advantage of the solution according to the invention is that the mounting bracket can also be used where there is little space between the lifted load and the machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The invention will now be described in more detail by way of example. In the accompanying drawings, FIG. 1 is a front elevation of the mounting bracket, FIG. 2 shows a side elevational view of the mounting bracket of FIG.

Giant. 1 shows a front elevation of a mounting bracket with supports χ, g which with supports 1 *. 2 * (FIGS. 2 and 3) form pairs of supports X, X ^, g, gj. The pairs of supports X, _X ^# , g, gj are interconnected by a transverse beam 6 and supported thereon by bearings 4, 6 rotatably and longitudinally displaceable.

Bearings $, £ are secured with clamping rings £ · The triangular joint surfaces £ give the bearing bracket the necessary rigidity against tilting moment and breaking. · Supports X, X * or g, g * form an abutment angle

On the supports X, X *, g, g 'are provided bearing brackets s with a pair of wheels X a and further attachment and guide components for the support angle change means mounted on the bearing bracket ·

In the exemplary embodiment (FIG. 8), this means consists of an engagement arm XX which operates on the principle of a gripping frog and is provided with an engagement lever 8, a return lever (not shown) and a rope Xg. on the bearing bracket 8 by means of a rope eye. They are provided on the bearing yoke

199 391 suitable means for the cable 12, the free length of which is wound on the cable drum 12 ', to be guided between the pairs of wheels 10. To transmit the traction or compression force to the engagement arm shown in the embodiment. hydraulic or pneumatic working units operating in a known manner, transmitting this force by means of a toothed rack, a threaded spindle or a chain drive with a sprocket, may be provided on pairs of supports 1, 1, * 2 »2 * ^for Pi '.

The mounting load (not shown) is mounted on the cross beam.

The device according to the invention flows as follows:

By actuating the engagement lever 14 or the return arm of the engagement arm II, not shown, the length of the rope 12 between the supports 1, 1 can be shortened or extended. This simultaneously forces the support spacing 1, 1 * 4 2 »2 *. cross-member 2 · The engagement arm 11 operates smoothly and without reverse, so that the mounting bracket can be adjusted from the smallest (Fig. 2) to the largest (Fig. 3) lift height in all positions by changing the support angle. While the stroke of the crossbeam 23 is caused by the force applied to the engagement arm 11, the crossbeam descends spontaneously when the rope 12 is released.

To prevent uneven lifting or lowering due to the different operating speeds for the engagement of the arms h pairs · abutments 1 Li 2 »2 ^ ⁸⁰¹¹ within the support angle formed by the pair of supports 1, 1» 2 »2 *» suspended svislioe which indicates the horizontal position of the transverse beam 2 ·

Horizontal manual shifting of the mounting bracket is carried out by means of wheel pairs 12, 10 / provided on the bearing brackets 2 »2 *. By releasing the clamping rings 2 it is possible that the pairs of supports 1, 1, 2» 2 * can be moved on the crossbeam 2 so possible continuous width adjustment, for example in case of insufficient floor space. Besides, it can. the mounting bracket can be disassembled by loosening the outer clamping rings g and pulling the bearings 4, 2 off the crossbeam 2 · Ti®, the crossbeam 2, the supports 1, 2 and the engagement arm H can be removed and transported individually to the mounting location. Since the load to be lifted can be directly mounted, i.e. without a load lift, on the crossbeam 20, the possible use of the mounting bracket can also be used in areas where the free height between the load and the ceiling is small.
