Abstract
The utility model provides a kind of telescopic spreader, including hanging beam, telescopic rod, supporting block and hydraulic cylinder, the telescopic rod is located at the both ends of the hanging beam, described telescopic rod one end connects the hanging beam, the affixed supporting block of the other end, the affixed hanging beam in described hydraulic cylinder one end, the affixed supporting block of the other end, the relatively described hanging beam sliding of the telescopic rod.Telescopic spreader provided by the utility model is mainly used for suspending U-shaped concrete beam in midair, can improve the efficiency of bridge construction easily into slinging U-shaped concrete beam after the opening of U-shaped concrete beam.
Description
Technical field
The utility model is related to bridge construction apparatus field, more particularly to a kind of telescopic spreader.
Background technology
During bridge construction, for precast bridge (generally U-shaped concrete beam), need to be sling using suspender.And U
There is inwardly projecting part in the opening of type concrete beam, this causes suspender to be difficult to enter and output place, or enters hardly possible after opening
To sling U-shaped concrete beam, the progress of bridge construction is influenced.
Utility model content
The purpose of this utility model is to provide a kind of telescopic spreaders, to solve the above problems.
The utility model provides a kind of telescopic spreader, including hanging beam, telescopic rod, supporting block and hydraulic cylinder, described flexible
Bar is located at the both ends of the hanging beam, and described telescopic rod one end connects the hanging beam, the affixed supporting block of the other end, the hydraulic pressure
The affixed hanging beam in oil cylinder one end, the affixed supporting block of the other end, the relatively described hanging beam sliding of the telescopic rod.
Optionally, the supporting block is in contact with U-shaped concrete beam, and the contact surface of the supporting block and U-shaped concrete beam is inclined-plane.
Optionally, the contact surface is equipped with protection board.
Optionally, the hydraulic cylinder is 4, there are two the both sides of the hanging beam are each.
Telescopic spreader provided by the utility model is mainly used for suspending U-shaped concrete beam in midair, can easily enter U-shaped concrete beam
U-shaped concrete beam is sling after opening, improves the efficiency of bridge construction.
Description of the drawings
Fig. 1 is the front view of telescopic spreader provided by the utility model；
Fig. 2 is the vertical view of telescopic spreader provided by the utility model.
Figure label：1- hanging beams；2- telescopic rods；3- hydraulic cylinders；4- supporting blocks；5-U type concrete beams；51- extensions.
Specific implementation mode
Below in conjunction with the drawings and specific embodiments to the utility model proposes telescopic spreader be described in further detail.Root
According to following explanation and claims, will be become apparent from feature the advantages of the utility model.It should be noted that attached drawing be all made of it is non-
Often simplified form and use non-accurate ratio, only to it is convenient, lucidly aid in illustrating the utility model embodiment
Purpose.
It please refers to Fig.1 and Fig. 2, the telescopic spreader includes hanging beam 1, telescopic rod 2, hydraulic cylinder 3 and supporting block 4, described
Telescopic rod 2 is located at the both ends of the hanging beam 1, and 2 one end of the telescopic rod connects the hanging beam 1, the affixed supporting block of the other end
4, the affixed hanging beam 1 in 3 one end of the hydraulic cylinder, the affixed supporting block 4 of the other end, the hydraulic cylinder 3 drive described
Supporting block 4 keeps supporting block 4 flexible to drive the relatively described girder 1 of telescopic rod 2 to slide.
The telescopic spreader is in original state before the opening for entering U-shaped concrete beam 5, and hanging beam 1 adds telescopic rod
2 and supporting block 4 total length be less than U-shaped concrete beam 5 opening width, facilitate telescopic spreader enter U-shaped concrete beam 5 opening
In；After telescopic spreader integrally enters the opening of U-shaped concrete beam 5, hydraulic cylinder 3 drives supporting block 4 to move, and makes the supporting block at both ends
4 is inconsistent with the extension 51 of the U-shaped concrete beam 5, at this time can be pulled upwardly telescopic spreader, to hang U-shaped concrete beam 5
It rises；After by the suspention of U-shaped concrete beam 5, to after needing position, hydraulic cylinder is shunk, and so that telescopic spreader is returned to original state, then carry out down
One Secondary Suspension.
The supporting block 4 and the contact surface of the U-shaped concrete beam 5 are inclined-plane, so that supporting block 4 is bonded extension 51, increase connects
Tactile stability.It is additionally provided with protection board on the contact surface, protects the surface of U-shaped concrete beam 5.
The hydraulic cylinder 3 is 4, and there are two the both sides of the hanging beam 1 are each, 4 hydraulic cylinders 4 work at the same time, balance
The stress of supporting block 4 enhances stability.
Foregoing description is only the description to the utility model preferred embodiment, not to any limit of the scope of the utility model
Calmly, any change, the modification that the those of ordinary skill in the utility model field does according to the disclosure above content, belong to right and want
Seek the protection domain of book.
