CS261163B1 - Variable equipment for bridge segments handling - Google Patents

Abstract

The facility consists of a storage threshold joined at each end to the heel portion the support provided with the tooth on which it is attached the bent part of the support attached to the extension to store a horizontal beam composed of a support piece, an arbor part and extension piece, joined using cogs. Middle Extension, provided with a claw at both ends to assemble a gantry crane, stored on chassis. End extension parts allow you to assemble the same pair mounting devices mounted on hydraulic bearings and bearing feet anchor rod.

Description

The invention relates to a variable device for handling bridge segments composed of modular elements enabling the device to be converted to another.

One of the technology for the assembly of prefabricated bridge structures is the quick assembly of segments forward, using two identical mounting devices, advancing from the bridge abutments. As a rule, the respective assembly devices are not constantly loaded. They are temporarily stored with marked space requirements and must be laboriously conserved for corrosion protection, while in the same Sase no other handling equipment, which is expensive to purchase, is lacking in landfills or segment storage bins.

The above-mentioned drawbacks are overcome by a variable device for handling bridge segments consisting of at least two bogies on which there is a bearing threshold for at least two supports on which horizontal beams traveled by a crane trolley with a clamping lever are supported. The essence of the invention is that each of its supports is composed of a heel portion connected to a support threshold, to which a toothed portion of the support is connected, connected at the top to a horizontal beam support extension. It consists of a support part provided with a support projection at the bottom and a tooth on both ends to which one the cantilever part is connected and to the other is the extension of the horizontal beam. All teeth and flat joints are provided with contact plates for detachable bolt connection. The horizontal beam may include a central extension with a tooth at both ends. Alternatively, the horizontal beam may comprise an end piece having a tooth at one end and adapted to be supported on a support leg connected to the anchor rod at the other end.

The advantage of the variable device for handling bridge segments is that it allows a continuous workload of structural components, from which it is easy to assemble either a pair of assembly devices or a manipulating gantry crane or other similar device. The components are storable, which is especially beneficial when transported to the place of work. In the event of damage, a single component can be easily replaced by an intact one.

He did

The variable equipment assembled as a manipulating gantry crane consists of four bogies 9. ' ² , each of which is supported on two adjacent storage thresholds 5, connected at each end to the heel of the support. Each heel portion of the support is provided with a tooth on which a cranked portion 4 of the support is attached, connected at the top to a horizontal beam support 10, consisting of a support piece 3 provided with a support protrusion at the bottom and a tooth at both ends. A cantilever part 2 of the horizontal beam is connected to one of the two cogs and to the other is connected to the other one by means of a cog one end of the central extension piece 11 whose center of the symmetrically symmetrically assembled handling gantry crane. All claws and flat joints are provided with contact plates for detachable bolt connection.

Example 2

A variable device assembled as a pair of identical mounting devices, each consisting of a bearing threshold mounted on a pair of hydraulic bearings, which at each end is connected to the foot of the support. Each foot portion is provided with a tooth on which a cranked support portion 4 is mounted, on which a horizontal beam is mounted, consisting of a support piece provided with a support projection at the bottom and a tooth on both ends. The cantilever part 2 of the horizontal beam is connected to one of the two cogs, and to the other is connected the end extension piece 6 provided at the other end for mounting on a support leg connected to the anchor rod. The assembled horizontal beam of the mounting device is adapted for traveling by a crane trolley 1.

with clamping lever J). All teeth and flat joints are provided with contact plates for detachable bolt connection.
