Device for loading Sohachtringen öd «dgl ·

The invention relates to a device for loading Sohachtringen od.dglo using of pressure elements that act on the inside of the rings and can be actuated by a lifting rod.

With this device, the manhole rings should at best be stacked one on top of the other Number can be transported on a crane hook o

Through the US-PS 2,718,426 devices for loading manhole rings are already known, in which a plurality of fingers arranged in pairs are attached to a common bar, which are separated by a spring-loaded rod are spreadable. To load the manhole rings, they must be set up in mutually aligned rows so that when the device is lowered, a pair of fingers enters each manhole ring »Through common Actuation of the rods of the pinger pairs these are pressed against the inner wall of the manhole rings, the spring existing in the linkage of each pair of fingers dimensional differences in the inner diameter of the Manhole rings should compensate. The disadvantage of this device is its high susceptibility to failure by the arrangement of the plurality of springs as well as the

cumbersome way of working due to the necessity of the rings around them with the device to be able to fassfisi "

In order to eliminate these Naohteile, is a device of the type mentioned according to the invention proposed that at least two, preferably three pressure bars arranged at the same angular intervals via spreading levers od.dglo to a common one Shaft are connected to two axially spaced locations from which the one connection point on the shaft fixed in the axial direction and the other preferably as a concentric one Tube formed, adjustable and that at least one of the two Ansohlußstellträger one in a hoist has e.g. a crane hook that can be hooked in

With this device, manhole rings can be stacked individually or one on top of the other, depending on the length of the pressure beams can be transported effortlessly and with a high level of security.

Further details of the invention are explained in more detail with reference to the drawing, in which an exemplary embodiment of the device according to the invention for the transport of several stacked shaft rings is shown. It shows Pig in a similarly themed version. 1 the device in longitudinal section, Pig · 2 the top of the device in a different operating position and Pig. 3 is a partial cross-section of the device.

Like in Pig. 1 shown, the device has a main support from a tube 5 »in which

another tube 6 is inserted. An upper bracket 8 is firmly welded to the tube 5 · The tube 6 has a normal hanging hook. So that the tabs on the tube 6 can slide up and down, the tube 5 is equipped with longitudinal slots. Adjustable connecting pieces 13 and 14 now extend from the outer tube 5 to the pressure bar 10 _e

Like in Pig. 3, these connecting pieces are arranged adjustable in length. the Adjustment takes place by means of the adjustment pin 16 · For this purpose 14 holes are provided in the inner piece « The device according to FIG. 1 is adjusted to the diameter by means of this adjusting device the soleplate set. Go from Irinenrohr 6 from the tabs 15 connecting pieces to the pressure beam 1Oo all of these connectors are through the bolts 12 connected to each other. The beams 10 have a strong one because of the better adhesion and surface friction Slsitschutsauflage 11 glued or riveted, which at the appropriate moment on the wall of the Schaohtring 2 is pressed. So that the underbody 1 of the storage area is not damaged when the device is lowered is, the tube 5 has a plate at the foot, which can also be covered with a soft pad if necessary can. Depending on requirements, for example two or more pressure bars can be arranged on this device «

The soling ring on the hook 7 »which is welded to the pipe. prevents total collapse the ring hoist and thus also ensures that this can be placed freely on the base plate 4.

The transport now proceeds as follows: the machinist takes; initially with the Haksn 17 the G-liedring

7505729 06/26/75

9, pulls up and lets the device into the manhole rings. Then he lowers the hook 17 white - ter from and hangs the bracket 9 in the hook 7 on the tube (see Fig. 2). When pulling up, the connectors 13 printed outwards, this process is brought about exclusively through the pipe 6, which is now pulled along with it. " The bars 10 with the anti-skid pad 11 are now pressed against the wall of the Schaohtringe and taken upwards. Of the The advantage of this is that the machine operator never has to get off the device to move the hook A skilled crane operator can also pick up the link ring 9 from the chassis. So now a whole series of manhole rings can be transported effortlessly and with little loss of time. This is special When transporting by truck this is an advantage, because loading and unloading with a crane boom can be done quickly by the driver can be done. The whole device is relatively light and can be taken with you every time you transport it, will·

A very important advantage lies in that The fact that no complex hydraulic machinery is required for the whole process and the acquisition costs this device are small.

This device is because of an economically working precast or concrete plant the time saving of great advantage, for the operating personnel of such a plant a work relief and reducing the risk of accidents

The very simple transfer device 7, 8 and 9 allows perfect operation and is not susceptible to any complicated arrangement.

This device can be produced for any size of rings, primarily manhole rings be, it must still be noted that a single device largely for different The manhole ring diameter is adjustable β
