Description
Technical field
The utility model relates to the device detected for auxiliary railroad bridge, is exactly railroad bridge auxiliary detection platform specifically.
Background technology
Explanation of nouns: railroad bridge auxiliary detection platform, refer to ensureing safety, be suitable for, under easy, the prerequisite that do not affect railway operation for testing staff provides the operating platform of detection, layout test point below beam body.Plateform system is the trussed construction of aluminium alloy structure, and effect is carrying testing staff and checkout equipment thereof, for it provides a safety, applicable operating platform.
The defect of the hanging basket system of existing railroad bridge auxiliary detection platform is: what barrel structure adopted is that stainless steel material is made, and deadweight is comparatively large, limits testing staff and plant and instrument carries quantity, and operating efficiency is affected.Hanging basket system is comparatively large at wind-force effect lower swing, has a strong impact on the work of testing staff, and there is larger potential safety hazard.Testing staff's limitation of activity, is difficult to realize at frange plate or web higher position installation elements or detection.
Summary of the invention
The utility model is in order to solve the problems of the technologies described above, provide a kind of railroad bridge auxiliary detection platform, the technical scheme taked is: platform is trussed construction, it is characterized in that: also comprise platform stop, its structure is for be socketed with removable slide block at upper chord, and removable slide block is fixed by screw rod and upper chord, and removable slide block is provided with limited block, screw rod, through limited block, plays fixation by snap; Chord member is provided with detachable guardrail, adds testing staff's scope of activities, make testing more comprehensively and safety.
Described platform stop is removable on upper chord, is arranged in span centre position.
The top-bottom chord of platform is fixed with detachable guardrail; cat ladder is fixed on platform chord member; detachable guardrail can be assembled and disassemble within a short period of time, and cat ladder is that staff provides up and down space, works safer under the protection of detachable guardrail.
Described platform adopts alusil alloy material to make.
The utility model has the advantage of: installed removable constraint at platform upper, that walks about produce with across-wind dynamic load effect due to personnel when reducing work high above the ground rocks, and structure has certain wind loading rating, improves the stability of its work.Platform is installed the fixed constraint of cat ladder, can be safer during such person works, activity space is larger; Platform structure material selection processing characteristics and the good alusil alloy of welding performance, optimize structural element sectional dimension simultaneously, makes structure more light, and component stress meets the demands simultaneously, reduces required thrust in the implementation of bridge floor running gear.
Accompanying drawing explanation
Fig. 1 is sectional drawing of the present utility model.
Fig. 2 is the structure for amplifying schematic diagram of limited block.
Fig. 3 is the structural representation of stabilising arrangement.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of railroad bridge auxiliary detection platform, comprise platform 1 body, arrange platform stop at platform 1, its structure for be socketed with some stabilising arrangements 2 on upper chord.The bottom of stabilising arrangement 2 offers screw, is fastened on the upper chord of platform, plays position-limiting action by lower screw 10.When needing the position of mobile stabilising arrangement 2, only lower screw 10 need be unscrewed.There is fixed mount at stabilising arrangement 2 upper weld, fixed mount is welded with the limited block 9 with screw.The metal that this limited block 9 generally adopts stainless steel etc. to have hard quality is made.Limited block 9 also offers screw, and on this screw, is plugged with the Limit screw 11 that length is greater than limited block.
During use, stabilising arrangement 2 is fixed on the position of square beam body 6 under bridge, back-outed by Limit screw 11, hold out against beam body 6 bottom side, when four limited blocks 9 all hold out against 6 end of beam body, platform 1 is just fixed.After above-mentioned stabilising arrangement 2 is installed on the platform 1, can platform 1 is temporary fixed with beam body 6 structure together with, effectively prevent the impact of work high above the ground wind load on service work, in addition, also solve the impact of swing for superstructure of platform 1, and flexible operation, convenient.
The top-bottom chord of platform 1 is also fixed with detachable guardrail 3, assembly and connection can be carried out by pin inserted mode.After determining the position of construction, detachable guardrail first installed by platform 1 chord member, then cat ladder 4 is fixed on platform 1 chord member position by rotating shaft, play fixing effect, the safety when setting of detachable guardrail 3 also ensure that testing staff works, detachable guardrail 3 and cat ladder 4 form scalable, foldable structure, make each position of the arrival beam body that operating personnel can be wider, make to detect more comprehensively thoroughly.
Use operating process:
Assembling process operates: first testing staff needs the counterweight carrying out computing system according to Detection task, testing staff's quantity, plant and instrument use amount, carry out the installation of bridge floor walking system subsequently, platform 1 is placed on ground immediately below bridge floor walking system, bridge floor walking system and railroad bridge auxiliary detection platform is connected with boom hoist cable 7, the Hoisting System 5 of operating personnel operating platform both sides under bridge, the position detected is applicable under platform 1 being promoted to bridge, now platform wire rope 8 is hung to bridge floor walking system, all distribute the stressed of boom hoist cable 7.
The course of work operates: to platform 1 on testing staff and equipment, testing staff's safety rope is fixed to bridge floor walking system, bridge floor walking system is carried out to detecting each position along bridge is longitudinally synchronous by bridge floor operating personnel, after platform stops, the transfer of testing staff's safety rope is fixed on the steel work of sidewalk, stabilising arrangement 2 is adopted to be fixed to by platform below beam body 6, start assembled detachable guardrail 3 and cat ladder 4 subsequently, when detachable guardrail 3 is assembled, each reinforcement component must insert in pin completely, the rotating shaft of fixing cat ladder 4 also must put into draw-in groove completely, testing staff can carry out work along cat ladder about 4 subsequently.
Disassemble process operation: after to be detected, first remove detachable guardrail 3 and cat ladder 4, then remove the fixing of stabilising arrangement 2, bridge floor walking system is carried out to bridge pier place by bridge floor operating personnel, testing staff and equipment remove platform 1, and demolishing process is the contrary operation of installation process.
