Abstract
The utility model discloses a horizontal translation device of tunnel secondary lining platform truck superstructure adopts the structure of twining that rolls, and it includes scroll box (1), roller bearing (2) and limit baffle (3), scroll box (1) is formed by longeron (1 -1), crossbeam (1 -2) and floor (1 -3) welding, connects two crossbeams (1 -2) between longeron (1 -1) the end of two parallels respectively, drilling on longeron (1 -1), wear in longeron (1 -1's) hole at the both ends of roller bearing (2), and limit baffle (3) are connected on entablature (4) of platform truck, are located longeron (1 -1) the both sides of two parallels. When lining cutting platform truck upper portion needed the translation, roller bearing in the roll dish played the effect of rolling wood between longeron and the entablature on the platform truck, replace sliding friction with rolling friction, had reduced on the platform truck frictional force between longeron and the entablature greatly, made the horizontal translation of platform truck more effective.
Description
Technical field
It is horizontal that this utility model is related to a kind of secondary lining chassis superstructure adopted in Tunnel Second Lining Construction
Translating device.
Background technology
In the past, the transverse translation of Tunnel Second Lining chassis superstructure used dolly or face contact slide.It is little
The physical dimension and weight of car is larger, and materials'use is more, makes also comparatively laborious time-consuming；Face contact slide frame mode
Although simple, material is most saved, and the frictional force which produces when chassis superstructure is heavier is very big, in order to promote chassis top
Structure, then need to increase the cylinder diameter of oil cylinder or improve the operating pressure of oil circuit, also need to strengthen the connecting hinge portions position of oil cylinder
Process, also increase indirectly cost.It is therefore necessary to developing a kind of new translating device to solve the upper of secondary lining chassis
Portion's structure transverse translation problem.
The content of the invention
The technical problems to be solved in the utility model is：A kind of Tunnel Second Lining chassis superstructure transverse translation is provided
Device, to adapt to needs of the secondary lining chassis in lining construction superstructure transverse translation, overcomes prior art to deposit
Waste of material, make the deficiencies such as loaded down with trivial details time-consuming, cost is high.
The technical solution of the utility model is：Using dish structure is rolled, it includes scroll box, arranges roller bearing inframe is rolled
And postive stop baffle.
Scroll box is welded by longeron, crossbeam and floor, between two parallel longeron terminations connects two respectively
Crossbeam；Drill on longeron, the two ends of roller bearing are through in the hole of longeron, and postive stop baffle is connected on the entablature of chassis, is located at
Two parallel longeron both sides.
Floor is welded on longeron, parallel with crossbeam.
Roller bearing is Step Shaft, and respectively through in the hole of the longeron of both sides, the axis of roller bearing is vertical with longeron at axle two ends, with horizontal stroke
Liangping row.
The horizontal depth of beam of scroll box is higher by 20mm upwards than longeron and roller bearing.
The translation of Tunnel Second Lining chassis superstructure using rolling disk device, rolling disk be placed in the entablature of chassis with it is upper
Between longeron, play and the sliding friction between entablature and upper longeron be changed into into rolling friction, reduce the frictional force between both,
So that the transverse translation of chassis is more effective.
This utility model has been successfully applied to the secondary lining that tunnel list pairing in elder brother's Line for Passenger Transportation Feng huangshan Mountain, Shanghai repaiies changeover portion
In chassis, the chassis original adoption is face contact slide structure, but has ultimately resulted in the office of translation oil cylinder connecting hinge portions position
Portion destroys, and superstructure can not be translated.Thereafter translation is successfully solved using rolling disk translating device described in the utility model
Problem.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 makees structural representation during parallel-moving type for this utility model.
Specific embodiment
Embodiment of the present utility model：Using dish structure is rolled, it includes scroll box 1, arranges 2 He of roller bearing inframe is rolled
Postive stop baffle 3.Scroll box 1 is welded by longeron 1-1, crossbeam 1-2 and floor 1-3, two parallel longeron 1-1's
Connect two crossbeam 1-2 between termination respectively；Drill on longeron 1-1, the two ends of roller bearing 2 are through in the hole of longeron 1-1,
Postive stop baffle 3 is connected on the entablature 4 of chassis, positioned at two parallel longeron 1-1 both sides.
Floor 1-3 is welded on longeron 1-1, parallel with crossbeam 1-2.
Roller bearing 2 is Step Shaft, axle two ends respectively through in the hole of the longeron 1-1 of both sides, axis and the longeron 1- of roller bearing 2
1 is vertical, parallel with crossbeam 1-2.
The height of crossbeam 1-2 is higher by 20mm upwards than longeron 1-1 and roller bearing 2.
Postive stop baffle 3 adopts welding or bolt connection with the entablature 4 of chassis.
As schematically shown in Figure 2, when lining trolley top needs transverse translation, the roller bearing 2 in rolling disk is in chassis entablature 4
Play between upper longeron 5 rolling wood effect, replace sliding friction with rolling friction, substantially reduce chassis entablature 4 with it is upper
Frictional force between longeron 5, makes the transverse translation of chassis more effective.Scroll box 1 ensure that the ordered movement of roller bearing 2, floor 1-
3 intensity that ensure that scroll box, postive stop baffle 3 ensure that the direction of motion of translating device.Crossbeam 1-2 be higher by longeron 1-1 and
The part of roller bearing 2 ensure that translating device longeron 5 without departing from chassis superstructure transverse translation.
