Abstract
The utility model relates to a multipurpose box girder lifting hole pitch conversion device, used for an adjusting device during box girder lifting operation in the box girder prefabricating and erecting process in high-speed railway construction. The lifting appliance on each side of the box girder lifting device is provided with two steel structure shoulder pole beams shaped like a Chinese character ji; two pairs of lifting holes with the pitch of 3800mm and 3400mm are arranged on each shoulder pole; each shoulder pole passes through the lifting hole with the pitch of 3400mm through two connection suspenders and is connected with the original lifting appliance; and the original suspender is disassembled and mounted in the lifting hole with the pitch of 3800mm. The device is mounted on the original box girder lifting device and can meet the non-standard box girder lifting construction with the pitch of 3800mm. The utility model has the advantages of convenient assembly and disassembly, simple structure and few consumed materials. The lifting hole pitch conversion device can be used for a rubber-tyred transporter with a 900t box girder, or wheel track type girder elevator and bridge girder erection machine with a 900t box girder. As the pitch utilizes the standard size, the utility model is suitable for the device interfaces of different manufacturers.
Description
Technical field
The utility model relates to a kind of nonstandard beam type hole for hoist distance and the existing equipment lifting servicing unit under the situation that do not match, be specifically a kind of case beam hole for hoist apart from conversion equipment, this device is applicable to that Line for Passenger Transportation 900t is with nowel beam lifting operation.
Background technology
In special line for passenger trains construction, that 900t case beam is generally taked is prefabricated-form of construction work of transporting-setting up, the case beam needs repeatedly transition lifting.Case beam lifting is generally carried out with lifting beam machine, carrying implement and bridge formation machine, and the connected mode of lifting is to utilize that the fixed derrick of suspender penetrates 8 holes for hoist that case beam both sides are provided with respectively on the hanging device, and packing ring is installed then, locks with nut at last.Hole for hoist is apart from being generally 1000mm*3400mm or 1000mm*3660mm, and case beam hanging device is generally by above-mentioned size design suspender.But in the individual design scheme; The case beam such as the 1000mm*3800mm of nonstandard pitch-row are arranged, and existing gauge orifice can't use apart from equipment, and way is again the making apparatus suspender usually; But this way consumable material is many, the process-cycle long, distinct device will be made respectively, and cost is very high.
Summary of the invention
In order to solve the problem of above-mentioned existence; The utility model provides a kind of Multi-purpose box beam hole for hoist apart from conversion equipment; This conversion equipment can let the hanging device of existing gauge orifice distance be used for the lifting operation of nonstandard beam type, with the following case beam hanging device of the 900t that also can be used for different model and kind.
The purpose of the invention is to realize through following technical scheme: Multi-purpose box beam hole for hoist is apart from conversion equipment; It is characterized in that: every side suspender of case beam hanging device is furnished with more than two Zee bar steel Z structure shoulder pole girders; On every shoulder pole girder, making pitch-row respectively is two pairs of holes for hoist of 3800mm and 3400mm; Every shoulder pole girder passes hole for hoist and the original suspender that pitch-row is 3400mm through two connection suspension rods and links together, and is installed in the hole for hoist that pitch-row is 3800mm after former suspension rod is unloaded.
On the connection suspension rod, install and heighten the pad tube.
The beneficial effect of the utility model: the utility model adopts said structure, is installed on original case beam hanging device, can satisfy the non-standard packing box beam lifting construction operation of 3800mm pitch-row.And do not change former hanging device hanger structure and function, just utilize existing hole for hoist of former suspender and suspension rod, be applicable to that still gauge orifice lifts apart from 3400mm.Wherein shoulder pole girder adopts the Q345C steel to make, and heightens the pad tube and adopts the 45# steel to do, and connects suspension rod and nut and adopts DG34CrNiMo to make, and pad adopts the 35# steel to do.Through checking, the strength and stiffness that connect suspension rod and shoulder pole girder meet instructions for use; Through adjusting pad tube height, can satisfy the variation of distinct device suspender size.The utlity model has easy accessibility, structure is light and handy, and the advantage that consumable material is few is compared with the new suspender of processing, reduces running cost.This hole for hoist promptly can be used for the rubber-tyred carrying implement of 900t case beam apart from conversion equipment, also can be used for the wheel-track type lifting beam machine and the bridge formation machine of 900t case beam, because of connecting hole apart from adopting standard size, can realize equipment interface simultaneously with each different manufacturers.

The specific embodiment
Multi-purpose box beam hole for hoist is apart from conversion equipment; Every side suspender of case beam hanging device is furnished with more than two Zee bar steel Z structure shoulder pole girders 5; On every shoulder pole girder 5, making pitch-row respectively is two pairs of holes for hoist of 3800mm and 3400mm; Every shoulder pole girder 5 passes hole for hoist and the original suspender 6 that pitch-row is 3400mm through two connection suspension rods 4 and links together, and each two ends that connect suspension rod 4 is provided with suspension rod packing ring 2 and nut 1.During use, be installed in after former suspension rod 7 unloaded that pitch-row is in the hole for hoist of 3800mm on the shoulder pole girder 5.
Can on each connection suspension rod 4, install one as required and heighten pad tube 3,, satisfy the variation of distinct device suspender size through adjusting pad tube height.
Case beam hanging device need be equipped with more than 4 Zee bar steel Z structure shoulder pole girders, 8 connect suspension rod, 16 cover suspension rod packing rings and nut, 8 heighten the pad tube.
Claims (2)
