Abstract
The utility model relates to a rail adjuster. The rail adjuster is characterized by comprising a main sleeve (5), a sleeve cover (6) is arranged at the top of the main sleeve, one side of the main sleeve is connected with a driving shaft (9) matched with the main sleeve in a rotating mode, a first bevel gear (9a) is arranged at one end of the driving shaft, a wrench (9b) is arranged at the other end of the driving shaft, a screw rod (4) is arranged in the main sleeve, a second bevel gear (4b) is arranged on the screw rod, the second bevel gear and the first bevel gear mesh with each other, the upper end of the screw rod is connected to the sleeve cover through a bearing seat (8), an auxiliary sleeve (2) is connected with the lower end of the screw rod, and an outer circle of the auxiliary sleeve is in clearance fit with an inner hole of the main sleeve. The rail adjuster has the advantages of being simple in structure, convenient to operate and high in adaptability, and reduces production and use cost and shortens the construction period of rail construction while improving mounting efficiency and mounting precision of a rail.
Description
Technical field
The utility model relates to a kind of adjuster, particularly a kind of rail adjuster.
Background technology
In construction of railways, mostly lay at present non-fragment orbit.Before to non-fragment orbit second pouring, need to carry out the adjustment location in horizontal direction and vertical direction to track, to meet the needs of train running.Existing adjuster needs many people to operate together, and labour intensity is large, and efficiency is low, and manufacturing cost and use cost is high.
Summary of the invention
The purpose of this utility model is to solve the unhandy problem of adjuster under prior art, and a kind of rail adjuster of convenient operation is provided.
The purpose of this utility model is achieved by the following technical programs:
A kind of rail adjuster, is characterized in that comprising master collet, and master collet top is provided with cover, and master collet one side is connected with the driving shaft being rotatably assorted with it, and driving shaft one end is provided with the first bevel gear, and its other end is provided with spanner; In master collet, be provided with screw rod, screw rod is provided with the second bevel gear, and the second bevel gear and the first bevel gear are intermeshing, and screw rod upper end is connected on cover by bearing support, and screw rod lower end is connected with secondary case cylinder, secondary case cylinder cylindrical and master collet endoporus matched in clearance.
Described spanner is the commercially available ratchet spanner in market.
On the basis of technique scheme, can also there is following further technical scheme:
Along secondary case cylinder be axially provided with chute thereon, master collet bottom is provided with fixing slide block, fixing slide block and chute are slidably matched, in order to limit the stroke of secondary case cylinder in master collet.
Cover is provided with a pair of wing seat, and wing seat is provided with installing hole.
The bottom of secondary case cylinder is provided with nigger, in the stroke deficiency of, secondary case cylinder large for Tunnel footpath.
The beneficial effects of the utility model are simple in structure, simple operation, and applicability is strong, and when improving the installation effectiveness and installation accuracy of track, has reduced production and use cost, has shortened the construction period of orbit construction.
Just accompanying drawings and embodiment further illustrate the utility model below.
