Description

A kind of bridge pad inspection ladder
[technical field]
The present invention relates to a kind of bridge pad testing fixture, especially relate to a kind of inspection ladder that is applicable to the high ferro bridge pad.
[background technology]
Known, the effect of bridge pad is to bear whole loads that the top crossstructure transmits, and gives ground they and the bridge pier structure Load Transfer of bottom through bearing.Therefore, use with normal, not only require ground and basis that enough intensity, rigidity and resistance to overturning will be arranged, also require in service life, should regularly carry out maintenance, guarantee the normal operating conditions of bearing for bridge pad for the safety of full-bridge.
Existing bridge mainly is divided into; Beam bridge, arch formula bridge, cable stayed bridge, suspension bridge etc., bridge generally consists of the following components: bridge span structure, bridge pier and abutment, basis, superstructure, bearing and truncated cone banking etc.; Support system generally is divided into fixed bearing and freely movable bearing, is arranged on power transmission and linkage between the upper and lower structure of bridge; Its effect be the various Load Transfer of superstructure to pier, and adapt to mobile load, variations in temperature, concrete shrinkage and the displacement that factor produced such as creep, make the actual loading situation of bridge meet the structural calculation diagram; The design period of general bridge according to the Ministry of Construction 2000 put into effect about architectural design series of standards service life, regulation Bridges in Our Country design life is 100 years to 120 years; But since the support system of the bridge span structure of bridge bottom, bridge pier in long-term use or earthquake, for a long time during phenomenons generation such as structural displacement gradually; For the bridge span structure of bridge bottom, bridge pier bearing pad system check, in the layout of test or test point, when the especially inspection of support system, test near they very difficulties that seems.
Especially in the construction at full speed of high ferro or inter-city passenger rail; Large span, bridge be high to surpass comparatively common more than 10 meters; Because high ferro or inter-city passenger rail are much built in the personnel compact district; So the basic cat ladder that is not provided with from the bridge pier bottom is bigger for inspection, the difficulty of test of support system.
The inventor is at the bottom of the bridge that discloses a kind of bridge in the Chinese patent of first to file " at the bottom of a kind of bridge of bridge and support system inspection dolly; notice of authorization CN101476285B, the applying date on 01 09th, 2009 " and bearing inspection dolly; This patent is found the high ferro that incompatibility is present or the bearing inspection work of inter-city passenger rail in implementation process; Because weight length heavier and existing fence is lacked " length on every rhizosphere hurdle is about 15 meters "; Meet interface and just need unload installation once more down, very inconvenient.
[summary of the invention]
In order to overcome the deficiency in the background technology; The present invention discloses a kind of bridge pad inspection ladder; Said bridge pad inspection ladder connects through the clump subcard that semicircle hook and bridge two upper lateral parts are set on montant top or is enclosed within on the railing through the half slot that is provided with on the semicircle hook; Through hand-held as detection instrument or telescope or range estimation detects the bridge bottom surface or the bridge pier system detects a flaw because structure of the present invention is comparatively simple, but a just operation of people.
For realizing the foregoing invention purpose, the present invention adopts following technical scheme:
A kind of bridge pad inspection ladder; Comprise montant, cat ladder cross bar, suspension rod, platform cross bar, backguy, semicircle hook, spill spin block, runner, fixture block A, fixture block B and screw rod; Between two montants, be provided with complex root cat ladder cross bar, one side connects an end of suspension rod respectively through hinge in the lower end of two montants, between two suspension rods, is provided with many platform cross bars; The other end at two suspension rods is connected with an end of two backguys respectively, and the other end of two backguys connects the bottom of two montants; Opposite side two montant upper ends is respectively equipped with the semicircle hook; Link at two semicircles hook and two montants is respectively equipped with screw; Two screw rods respectively with the screw wire connection; One side towards semicircle hook bottom at two screw rods is respectively equipped with fixture block B, and the other end of linking up with at two semicircles is provided with to the perpendicular extension rod that extends below, the corresponding two semicircles hook screw side of being provided with, the top of said perpendicular extension rod opening; The both sides of two inherent two spill spin blocks of the spill spin block side of being separately positioned on opening are respectively equipped with axis hole; The bearing pin side of passing opening side walls and axis hole are pegged graft and are formed the adjustable angle of spill spin block, and two screw rods middle parts cooperate with the screw that the spill spin block middle part is provided with respectively, are respectively equipped with fixture block A at the end of the corresponding fixture block B of two screw rods; The other end at two screw rods is fixedly connected with runner respectively, and said two fixture block B and two fixture block A form being locked to railing.
Described bridge pad inspection ladder is provided with hinge and makes two montants form foldable structure at the middle part of said two montants.
Described bridge pad inspection ladder is provided with semicircle locked groove at the lateral surface middle part of fixture block A.
Described bridge pad inspection ladder is provided with the rubber antiskid face on the lateral surface of fixture block A.
Described bridge pad inspection ladder is provided with semicircle locked groove at the lateral surface middle part of fixture block B.
Described bridge pad inspection ladder is provided with the rubber antiskid face on the lateral surface of fixture block B.
Described bridge pad inspection ladder, the rounded structure of said runner is provided with at least two handles on the outer edge surface of circular configuration runner.
Described bridge pad inspection ladder is respectively equipped with on the top of two semicircles hooks and raises up, and the two ends of handrail raise up and are fixedly connected with two respectively.
Described bridge pad inspection ladder is provided with half slot at the undercut middle part of semicircle hook, and said half slot cover is stuck on the railing.
Because adopt aforesaid technical scheme, the present invention has following beneficial effect:
Bridge pad inspection ladder of the present invention; Through the semicircle hook is set on montant top, utilize the semicircle hook can directly hang on the Cement guard bar of fenceless bridge two upper lateral parts, also can go up the half slot that is provided with and be enclosed within on the railing through the semicircle hook; So that the bearing between inspection bridge and the bridge pier; The people stands on two platform cross bars between the suspension rod during inspection, observes through telescope during the bridge broad, can cross over to get on the bridge pier as carrier through plank when bridge is narrower and observe; In like manner, the present invention also can be through hand-held as detection instrument or telescope or range estimation detects the bridge bottom surface or the bridge pier system detects a flaw, if the position is improper; Can carry out operation so that arrive correct position through adjustment position of the present invention; The present invention is reclaimed in the inspection back that finishes, and the present invention is because structure is comparatively simple, can use light material such as aluminium alloys as montant, cat ladder cross bar, suspension rod and platform cross bar materials; Very light, but a just operation of people; It is heavy that the present invention has overcome existing checkout gear structure, and unhandy drawback is easy to apply.
