Abstract
The utility model discloses a novel anti-collision retractable device for highway bridges and relates to the technical field of bridge equipment. The lower end of an anti-collision base is connected with a connecting base through a buffer connecting block, a rotating rod sleeve is arranged inside the center of the anti-collision base, a threaded connecting rod is screwed in the rotating rod sleeve, an anti-collision block is arranged on the left side of the threaded connecting rod, and the left side of the anti-collision block is integrally connected with right sides of lower ends of anti-collision rubber blocks. The device is simple in structure, reasonable in design and convenient to operate; the threaded connecting rod is driven to move forwards and backwards through rotation of the rotating rod sleeve, so that the anti-collision block at the left end is driven to move forwards and backwards, and the adjustability of the retractable device is realized; meanwhile, the anti-collision rubber blocks are arranged on the left side and at the upper end of the retractable device and used for protecting the retractable device against collision damage.
Description
Technical field
The utility model relates to bridge equipment technical field, is specifically related to the crashproof stretching device of a kind of novel highway bridge.
Background technology
Fast development along with China's economic construction, the high-grade highway that the speedway of take is representative occurs as emerging rapidly in large numbersBamboo shoots after a spring rain, traffic volume of highway sharply increases, on highway, the travel speed of driving vehicle and the axle of vehicle focus on growth, people are more and more higher to the requirement of road-ability etc., therefore in bridge design, construction in the past, the problem of paying attention to inadequate relevant stretching device becomes more and more outstanding, forces bridge design, construction, conservation and management department to pay attention to fully this.
Existing Expansion Units for Highway Bridges directly bears the repeated stock effect of wheel load in bridge construction, and long term exposure is in atmosphere, environment for use is more severe, and after installing, cannot realize the effect of random adjusting, and when automobile clashes into for a long time to bridge extension joint, be easy to cause the damage of bridge extension joint.
Summary of the invention
The purpose of this utility model is to provide the crashproof stretching device of a kind of novel highway bridge; it is simple in structure, reasonable in design and easy to operate; highway bridge drives whorl brace rod to seesaw with crashproof stretching device by rotation swingle cover; thereby drive the anticollison block of left end to seesaw; realize the adjustability of stretching device; the left side of simultaneous retractable device and upper end are provided with anti-collision rubber piece, utilize the damage that is not impacted of anti-collision rubber block protection stretching device.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises crashproof seat 1, connection base 2, anticollison block 3, swingle cover 4, whorl brace rod 5, slows down contiguous block 6 and anti-collision rubber piece 7, the lower end of crashproof seat 1 is connected with connection base 2 by slowing down contiguous block 6, the central interior of crashproof seat 1 is provided with swingle cover 4, the inside of swingle cover 4 is connected with whorl brace rod 5, the left side of whorl brace rod 5 is provided with anticollison block 3, and the right side, lower end of the left side of anticollison block 3 and anti-collision rubber piece 7 connects as one.
The right-hand member of described swingle cover 4 is rectangular configuration.
The utility model operating principle: highway bridge is connected with bridge foundation by connecting base 2 with crashproof stretching device, after highway bridge installs with crashproof stretching device, by rotation swingle cover 4, drive the anticollison block 3 of whorl brace rod 5 left ends to seesaw, utilize the anti-collision rubber piece 7 of anticollison block 3 front ends and upside to make highway bridge play crashproof effect with crashproof stretching device, connect simultaneously between base 2 and crashproof seat 1, be also provided with for secondary shock-absorbing slow down contiguous block 6, better play crashproof effect.
The utlity model has following beneficial effect: it is simple in structure, reasonable in design and easy to operate; highway bridge drives whorl brace rod to seesaw with crashproof stretching device by rotation swingle cover; thereby drive the anticollison block of left end to seesaw; realize the adjustability of stretching device; the left side of simultaneous retractable device and upper end are provided with anti-collision rubber piece, utilize the damage that is not impacted of anti-collision rubber block protection stretching device.
Accompanying drawing explanation:
Fig. 1 is the utility model structural representation;
