According to the trailer provided by the invention, the friction between the Bailey beam and a transverse distribution beam is reduced in the disassembly process, so that the security risks are effectively avoided.
Description
[technical field]
The present invention relates to dismounting construction equipment field, especially relate to a kind of for dismantle Bailey beam time for hauling the body construction of Bailey beam.
[background technology]
Known, Bailey beam is also known as beret truss, Bailey bracket or Bailey truss, due to it, to have structure simple, erection is quick, carrying capacity is large, interchangeability is good, the features such as structural system is good after strong adaptability and combination, therefore Bailey beam is not only used to assembled portal jib crane, nose girder, Bridge Erector or hanging basket etc., but also be widely used in highway, railway, municipal administration, building, the building projects such as water conservancy and bridge construction precasting yard lifting movement prefabricated units, the Contraction in Sites such as bridge pier other fortune dress crossbeam, namely Bailey beam is the supporting member of assembly type the most widely that China applies now, but owing to can be subject to the restriction of clear height when removing Bailey beam, thus causing Large-scale Hoisting equipment normally to use, therefore, is adopt corresponding plant equipment to utilize wire rope directly Bailey beam to be hauled out to the dismounting construction method of Bailey beam at present, but, rigid like this operation not only can produce huge frictional resistance between Bailey beam and transverse distribution beam, but also the deflection of Bailey beam can be increased in the process pulled, light then make the beam body of Bailey beam occur the distortion of unrepairable, have influence on the normal use of Bailey beam, heavy then cause the beam body of Bailey beam to break, cause scrapping of Bailey beam, bring danger to job site simultaneously also accordingly, threaten the safety of Field Force.
[summary of the invention]
In order to overcome the deficiency in background technology, the invention discloses a kind of Bailey beam dismounting tractor-trailer, described tractor-trailer can reduce the friction between Bailey beam and transverse distribution beam in unloading process, thus effectively avoids the generation of potential safety hazard.
For achieving the above object, the present invention adopts following technical scheme:
A kind of Bailey beam dismounting tractor-trailer, described tractor-trailer comprises top board, bracing frame, road wheel, screw rod and directive wheel; Described center, top board one end is provided with tow lug, and corresponding four the angle ends in top board bottom surface are respectively equipped with a bracing frame, and are provided with reinforcing connecting rod between two bracing frames of the same side; The bottom of four described bracing frames is equipped with road wheel, and the frame body of four bracing frames is equipped with the through hole of a level; All run through in four described through holes and be fixed with a screw rod, and four screw rods are positioned at same level, the inner termination of screw rod is all provided with directive wheel.
Described Bailey beam dismounting tractor-trailer, described top board is the steel plate that at least 20mm is thick.
Described Bailey beam dismounting tractor-trailer, described road wheel is that Steel material is made.
Described Bailey beam dismounting tractor-trailer, described screw rod is fixed by the nut being positioned at through hole two ends.
Described Bailey beam dismounting tractor-trailer, described directive wheel is set to scalable wheel.
Owing to adopting technical scheme as above, the present invention has following beneficial effect:
Bailey beam dismounting tractor-trailer structure of the present invention is simple, easy to use, described tractor-trailer can utilize oneself height effectively to overcome clear height restriction under the prerequisite in conjunction with job site concrete condition, and utilize the principle of pulley movement in unloading process, decrease friction between Bailey beam and transverse distribution beam, thus not only effectively control the deflection of Bailey beam, ensure the integrality of Bailey beam, but also effectively ensure that the safety of construction, and improve operating efficiency accordingly, reduce construction cost.

[detailed description of the invention]
Can explain the present invention in more detail by the following examples, disclose object of the present invention and be intended to protect all changes and improvements in the scope of the invention, the present invention is not limited to the following examples:
Bailey beam dismounting tractor-trailer Bailey beam dismounting tractor-trailer by reference to the accompanying drawings described in 1 ~ 2, described tractor-trailer comprises top board 1, bracing frame 2, road wheel 3, screw rod 4 and directive wheel 5; The steel plate having at least 20mm thick selected by described top board 1, the corresponding position close to four angle ends, its bottom surface is respectively equipped with a bracing frame 2, and the bottom of four bracing frames 2 is equipped with the road wheel 3 that Steel material is made, namely described tractor-trailer, when the support Bailey beam utilizing top board 1 firm, can carry out corresponding shift action by road wheel 3; For increasing the mobile convenience of described tractor-trailer after heavy burden further, tow lug 7 can be set in the back-end central position of top board 1, thus utilize corresponding machinery or the firm hooking between hoist engine and tow lug 7 to reach at the uniform velocity by object that described tractor-trailer pulls out;
For strengthening the holistic resistant behavior of described tractor-trailer, can reinforcing connecting rod 8 be set between two bracing frames 2 of the same side, top board 1 bottom surface, namely reinforcing connecting rod 8 is utilized firmly to be linked together by two bracing frames 2 before and after described tractor-trailer homonymy, thus make four bracing frames 2 form the stressed structure of an entirety, and then reach the object making the overall uniform force of described tractor-trailer, can lead safely in the process of hauling in Bailey beam, described tractor-trailer direction is avoided to wander off, the through hole 6 of one level can be set in the frame status of four bracing frames 2, and all run through in four through holes 6 and be fixed with a screw rod 4, the inner termination of this screw rod 4 is provided with the directive wheel 5 with telescopic structure, namely screw rod 4 corresponding clip utilizing these four to be positioned at same level is held in distribution beam 10 both sides below Bailey beam, thus reach the object enabling described tractor-trailer effectively carry out accurately location according to the width of distribution beam 10, and then ensure that the whole machine balancing of described tractor-trailer is stressed, the safety of effective guarantee Bailey beam in dismounting haul process, for being convenient to the position adjusting directive wheel 5 further, can arranging a nut 9 respectively fix screw rod 4 at the aperture place at through hole 6 two ends, namely every root screw rod 4 all can rely on two nuts 9 to fixedly positioning.
When implementing Bailey beam of the present invention dismounting tractor-trailer, first directive wheel 5 corresponding clip being positioned at both sides, top board 1 bottom surface is held in distribution beam 10 both sides of the Bailey beam bottom needing dismounting, directive wheel 5 is contacted with the sidewall of distribution beam 10 is corresponding, thus guarantee that described tractor-trailer can not be partial to, then, described tractor-trailer is moved to relevant position, Bailey beam bottom, and Bailey beam be seated on top board 1, then by corresponding machinery, described tractor-trailer is at the uniform velocity hauled out the dismounting haul operation namely completing Bailey beam; Reach a conclusion through practicing described Bailey beam dismounting tractor-trailer in the bridge engineering of Kua Chan river, North Road, riverfront, Luoyang City, described tractor-trailer can not only solve a difficult problem for clear height restriction in demolishing process, but also can effective reduction of erection time, improve workmanship and reduce engineering cost, thus the object obtaining distinct economic and social benefit is also reached while being subject to owner, management favorable comment, therefore, described tractor-trailer great popularization and application prospect.
Part not in the detailed description of the invention is prior art, therefore the present invention is not described in detail.
