Description
Technical field
This utility model relates to electric railway, compensates particularly to a kind of tunnel handle ratchet wheel and casts anchor adjustable rotary to fixed support.
Background technology
Along with developing rapidly of China's electric railway, there is broken string braking, ratchet that security reliability is high compensation device of casting anchor more and more is used, therefore, it is necessary to consider the various mount schemes of ratchet compensating device in high-speed electric railway.Particularly when tunnel section, ratchet compensation device of casting anchor expands in groove by the excavation that casts anchor that floor installation is reserved in tunnel, cast anchor fixing, turn to and anchored with tunnel-liner by crab-bolt with fixed support, it needs when installing comprehensively to take into account along tunnel radially, normal direction and the angle in tangential three directions of tunnel wall, for guaranteeing the transmission efficiency that ratchet compensates, compensate the most not clamping stagnation, therefore, require that this support bracket fastened installation accuracy is the highest, otherwise, if not reaching transmission efficiency requirement, then can have a strong impact on the normal work of contact net system, even cause train operation accident.
At present, electrified railway tunnels handle ratchet wheel compensates the mounting and fixing bracket that casts anchor and typically uses shaped steel combination superposition to be welded, and which fixed support shaped steel part is many, from great, it is impossible to make full use of the cross section property of shaped steel；Tunnel cross-section is required strict by this fixed support, is not suitable for the tunnel cross-section having excavation to expand groove, and after installation, contact wire and tunnel expansion groove face hypotelorism grind mutually, it may appear that the accidents such as broken string；Fixed support does not possess angle regulation function, it is impossible to meet multiple centenary design parameter, versatility and poor for applicability, if the most strictly controlling angle, will appear from after installation compensating rope grind mutually with support, pulley etc., the phenomenon such as clamping stagnation and transmission failure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of tunnel handle ratchet wheel and compensates the adjustable rotary that casts anchor to fixed support, the needs casted anchor with the contact net ratchet compensation of satisfied different tunnel cross-sections.
It is as follows that this utility model solves the technical scheme that its technical problem used:
Tunnel of the present utility model handle ratchet wheel compensates and casts anchor adjustable rotary to fixed support, rack body includes the supporting pillar of both sides, it is characterized in that: the outer end of the supporting pillar of described both sides is integrated by the upper horizontal support angle steel of longitudinally spaced setting, lower horizontal support Bolted angle connection；Upper horizontal support angle steel, the two ends of lower horizontal support angle steel are each provided with the Long Circle installing hole of one group of horizontal expansion；Respectively arrange one group in the two ends of upper horizontal support angle steel, lower horizontal support angle steel and adjust angle steel, the upper end adjusting angle steel arranges cross adjustment hole, its lower end arranges cross or vertically extending Long Circle adjustment hole, and each adjustment angle steel is fixedly mounted on upper horizontal support angle steel, lower horizontal support angle steel by securing member through corresponding installing hole, adjustment hole.
The beneficial effects of the utility model are, rational in infrastructure, easy construction, highly versatile, overall appearance, it is easy to safeguard, improve tunnel handle ratchet wheel and cast anchor the compensation transmission efficiency of compensation device, can meet the needs that the contact net ratchet compensation of difference tunnel cross-section is casted anchor.Can be widely used in various electric railway construction.

Component shown in figure and corresponding labelling: supporting pillar 1, upper horizontal support angle steel 2, lower horizontal support angle steel 3, adjustment angle steel 4, the most fixing angle steel 5.
Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Seeing figures.1.and.2, tunnel handle ratchet wheel compensates the adjustable rotary that casts anchor to fixed support, and rack body includes the supporting pillar 1 of both sides.The outer end of the supporting pillar 1 of described both sides is connected as one by the upper horizontal support angle steel 2 of longitudinally spaced setting, lower horizontal support angle steel 3.With reference to Fig. 3, upper horizontal support angle steel 2, the two ends of lower horizontal support angle steel 3 are each provided with the Long Circle installing hole of one group of horizontal expansion.With reference to Fig. 1, respectively arrange one group in the two ends of upper horizontal support angle steel 2, lower horizontal support angle steel 3 and adjust angle steel 4.With reference to Fig. 4, the upper end adjusting angle steel 4 arranges cross adjustment hole, and its lower end arranges cross or vertically extending Long Circle adjustment hole.With reference to Fig. 1, each adjustment angle steel 4 is fixedly mounted on upper horizontal support angle steel 2, lower horizontal support angle steel 3 by securing member through corresponding installing hole, adjustment hole.
With reference to Fig. 5 and Fig. 6, this utility model uses angle truss structure, the cross section property of Appropriate application angle steel, reduces the weight of whole support, reduces the additional load that deadweight produces, effectively reduces cost.Using the mounting means vertical with tunnel wall, at utmost reduce Framework construction size, more compact structure is reasonable, easy construction.By adjusting the adjusting hole of angle steel, ratchet can be adjusted within the specific limits and cast anchor the setting angle of compensation device, meet job site and needs are installed.Employing angle steel type supporting pillar and tunnel-liner anchor, and can expand groove size, the length of Reasonable adjustment angle steel type supporting pillar according to tunnel different section and excavation, it is ensured that contact wire and the distance of tunnel-liner, and the contact net ratchet of satisfied different tunnel cross-sections compensates and casts anchor.
The above this utility model tunnel handle ratchet wheel that simply explains through diagrams compensates and casts anchor adjustable rotary to more support bracket fastened principles, it is not intended to be confined to by this utility model in shown and described concrete structure and the scope of application, therefore every corresponding amendment being likely utilized and equivalent, belong to the apllied the scope of the claims of this utility model.
