The cantilever fixing device used for the subway interval protective and airtight separation door is arranged between the upper part of the separation door and the tunnel wall and is inserted and connected through the pin, the mounting is convenient, the length is adjustable, the large angular deviation is adapted, the connected device can be tightened rigidly through the puller bolt, and the problems that the cantilever fixing device cannot be processed in advance, and the mounting measurement and the detachment are difficult are solved.
Description
Technical field
The utility model relates to a kind of anchor fitting of subway partition door, particularly relates to a kind of cantilever anchor fitting for the airtight partition door of the interval protection of subway.
Background technology
Protect airtight partition door and be arranged at the subway interval, open at ordinary times, the time spent closes, and is positioned at tunnel one side during unlatching, and is parallel with current of traffic.The partition door bottom has jack safety device, jack to be fixed on the partition door, heads into downwards in the pre-buried base aperture in ground, plays load-bearing and fixing.Because of train by the time produce stronger piston wind, and door is high generally greater than 4500mm, the top cantilever vibrates greatlyyer, and the bottom jack safety device is had considerable influence, in case go wrong, consequence is hardly imaginable.Safety is firm more in order to make partition door, has at present between partition door top and tunnel wall according to the steel pipe of the two spacing welding different length or the way of shaped steel.This way, steel pipe or shaped steel are different in size after the dimensioned by actual measurement, and weldering after death can't be adjusted, and in addition, the welding back disconnects difficulty.
The utility model content
A purpose of the present utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, cost is low, install and disconnect the easy cantilever anchor fitting that is used for the airtight partition door of the interval protection of subway.
The purpose of this utility model can realize.The cantilever anchor fitting that the utility model is used for the airtight partition door of the interval protection of subway comprises subway partition door and subway tunnel wall, the cantilever anchor fitting that the utility model is used for the airtight partition door of the interval protection of subway is characterised in that: partition door pedestal of place, top welding of described partition door, lug on the described partition door pedestal connects the slotting ear of partition door joint left end with hole axle form by latch, the plus thread hole of the described partition door joint right-hand member thru-bolt that is threaded, the minus thread bar of described thru-bolt right-hand member is threaded with the minus thread hole of tunnel wall joint left end, described tunnel wall joint right-hand member welding two ends have the connection steel plate of connecting bore, the connection steel plate two ends of described tunnel wall joint connect semicircular ring with hole axle form, described semicircular ring is connected with the semicircular ring latch closure that is anchored at the pedestal set collar on the described tunnel wall by anchor bolt, the connection steel plate center of described tunnel wall joint is provided with a tapped bore, the puller bolt that is threaded on this tapped bore, the semicircular ring of the bolt head of described puller bolt and described pedestal set collar is to shore being fitted and connected of state.
The utility model is used for the cantilever anchor fitting of the airtight partition door of the interval protection of subway, the semicircular ring of the wherein said partition door pedestal that links into an integrated entity, partition door joint, thru-bolt, tunnel wall joint, semicircular ring, puller bolt and pedestal set collar is all an axis, and all acts on this axis for interval tensile stress or the compression effort that protects the cantilever anchor fitting of airtight partition door of subway.
The cantilever anchor fitting difference from prior art that the utility model is used for the airtight partition door of the interval protection of subway is that the utility model is used for the interval cantilever anchor fitting that protects airtight partition door of subway and is located between partition door top and the tunnel wall, peg graft easy for installation by latch, its length can steplessly be adjusted, can adapt to the wide-angle deviation, puller bolt holds out against the action of restriction semicircular ring, but rigidity held out against after connecting rod was connected.The utility model has solved under the airtight partition door complex working condition of protection, and the problem that measures and dismantle difficulty can not be processed, be installed to the cantilever anchor fitting in advance.
Below in conjunction with accompanying drawing the cantilever anchor fitting for the airtight partition door of the interval protection of subway of the present utility model is described further.
Description of drawings
Fig. 1 is for being used for the interval main TV structure scheme drawing that protects the cantilever anchor fitting of airtight partition door of subway.
Fig. 2 is for being used for the interval plan structure scheme drawing that protects the cantilever anchor fitting of airtight partition door of subway.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is used for the interval cantilever anchor fitting that protects airtight partition door of subway and comprises subway partition door 9 and subway tunnel wall 10.The utility model is used for partition door pedestal 1 of place, partition door 9 tops welding of the cantilever anchor fitting of the airtight partition door of the interval protection of subway, lug on the partition door pedestal 1 connects the slotting ear of partition door joint 3 left ends with hole axle form by latch 2, the plus thread hole of the partition door joint 3 right-hand members thru-bolt 4 that is threaded, the minus thread bar of thru-bolt 4 right-hand members is threaded with the minus thread hole of tunnel wall joint 5 left ends, tunnel wall joint 5 right-hand members welding two ends have the connection steel plate of connecting bore, the connection steel plate two ends of tunnel wall joint 5 connect semicircular ring 6 with hole axle form, and semicircular ring 6 is connected with the semicircular ring latch closure that is anchored at the pedestal set collar 7 on the tunnel wall 10 by anchor bolt.The connection steel plate center of tunnel wall joint 5 is provided with a tapped bore, and a puller bolt 8 is threaded on this tapped bore.The semicircular ring of the bolt head of puller bolt 8 and pedestal set collar 7 is to shore being fitted and connected of state.
