Abstract
The invention relates to a universal device of a subway interconnecting passage MJS reinforcing device power head. The universal device comprises a movable frame, a power head, a fixed frame, and a movable frame fixed locking device. The universal device is characterized in that the power head is arranged on the movable frame, the movable frame is rotatably connected with the fixed frame through a bearing and a bearing pedestal 3, so that the power head can be adjusted in any angle in the range of -30 DEG to 70 DEG. The movable frame fixed locking device is arranged between the fixed frame and the movable frame, and the movable frame fixed locking device is used for locking after angle adjustment of the power head 2. Through adding a universal structure frame on the rear of the power head, the power head can be adjusted in any angle in the range of -30 DEG to 70 DEG. After angle adjustment is completed, the power head is locked through a one-way cylinder added on a slideway and a strut on the rear end of a support. Aimed at part of relatively large tunnels, a lifting mechanism can be assembled on the lower part of the structure frame, and horizontal position of the device can be adjusted.
Description
Technical field
Patent of the present invention relates to a kind of excavation and reinforcement construction equipment of the strata metro tunnel connection channel in soft clay area and rich groundwater.
Background technology
At present, the excavation of service channel adopts construction freezing method substantially, because freezing process has stratum settlement to thaw collapse stage and long period in later stage after excavation, larger on the structure sediment impact of by-pass, differential settlement to this body structure of service channel and between service channel and tunnel structure connecting portion have serious destruction, sedimentation becomes irreversible common quality defect.Therefore my company and cooperation unit explore in tunnel the mode of carrying out MJS engineering method and adopting cement-soil to reinforce to the soil body, avoid freezing the future trouble that body thaw collapse brings, ensure the application life of subway, reduce later maintenance cost.
When adopting MJS engineering method to reinforce, because tunnel space limit, can only unit head decompose after carry out level and incline direction construction, be badly in need of research special purpose device and assist and carry out construction equipment and solve this and hold problem.
Summary of the invention
The object of the present invention is to provide a kind of in tunnel maintenance process, Metro Connection Passage MJS ruggedized equipment unit head universal head adjustable within the scope of from 30 ° to 150 °, this device can according to on-the-spot actual needs, in scope, arbitrarily angled adjustment Vertical tunnel sidewall carries out whitewashing reinforcement effect, overcome double track tunnel distance near, top, tunnel reinforces the problem of difficulty.
The present invention is realized by following technical scheme:
A kind of Metro Connection Passage MJS ruggedized equipment unit head universal head, comprise adjustable shelf, unit head, fixed mount, adjustable shelf fixing and locking device, it is characterized in that: described unit head is placed in above adjustable shelf, adjustable shelf to be rotatably connected fixed mount by bearing and bearing support 3, unit head is realized within the scope of from-30 ° to 70 ° arbitrarily angled adjustable; Adjustable shelf fixing and locking device is housed, for the locking after unit head 2 adjusting angle between described fixed mount and adjustable shelf.
Described adjustable shelf fixing and locking device comprises adjustable shelf articulated elements, support, earrings, slide block, one-way cylinder, described support two ends connect adjustable shelf articulated elements and slide block respectively by earrings, adjustable shelf articulated elements is fixedly connected on adjustable shelf side, slide block is connected with the slide be fixed on fixed mount, and slide block rear end connects one-way cylinder.
Described Metro Connection Passage MJS ruggedized equipment unit head universal head connects lifting appliance, for the level height of motivation of adjustment head center of rotation.
The present invention compared with prior art, has the following advantages and high-lighting effect:
1, compare with common universal whitewashing reinforcing technique, can realize-30 ° of any adjustments to 70 ° of angles, adjustable range is larger, affects less by extraneous factor.
2, support carries out locked by the fixing single-acting spring cylinder fixed by the connection pole between fixed mount and adjustable shelf and pole of unit head, when avoiding directly using two-way cylinder to unit head angular adjustment, owing to reveal in oil cylinder itself and hydraulic circuit is revealed and made angled change, more reliably, more stable, longer time uses.
3, lifting appliance is increased, can the level height of motivation of adjustment head center of rotation, adapts to the use of larger tunnel reinforcement.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figures 1 to 4: a kind of Metro Connection Passage MJS ruggedized equipment unit head universal head, comprises adjustable shelf 1, unit head 2, bearing and bearing support 3, adjustable shelf articulated elements 4, support 5, fixed mount 6, earrings 7, slide block 8, one-way cylinder 9.
Unit head 2 is placed in above adjustable shelf 1, and adjustable shelf 1 to be rotatably connected fixed mount 6 by bearing and bearing support 3, unit head 2 is realized within the scope of from-30 ° to 70 ° arbitrarily angled adjustable; Adjustable shelf fixing and locking device is housed, for the locking after unit head 2 adjusting angle between fixed mount and adjustable shelf.
Adjustable shelf fixing and locking device is made up of adjustable shelf articulated elements 4, support 5, earrings 7, slide block 8, one-way cylinder 9.
Support 5 two ends connect adjustable shelf articulated elements 4 and slide block 8 respectively by earrings 7, and adjustable shelf articulated elements 4 is fixedly connected on adjustable shelf 1 side, and slide block 8 is connected with the slide be fixed on fixed mount 6, and slide block 8 rear end connects one-way cylinder 9.
Metro Connection Passage MJS ruggedized equipment unit head universal head connects lifting appliance, for the level height of motivation of adjustment head center of rotation.
This apparatus function is: as Fig. 1, and shown in 2, meeting unit head take center of rotation as the center of circle, and 100 ° rotate the function of whitewashing.
Be arranged on adjustable shelf 1 by fastening for unit head, squeeze into hydraulic oil to one-way cylinder 9, unclamp slide block and guide rail, the position of adjustment slide block 8, change the angle extremely required angle between adjustable shelf 1 and fixed mount 6, the pressure in release one-way cylinder 9, makes slide block 8 clamping guide-rail.
By the universal structure frame installed additional at unit head, realize within the scope of from-30 ° to 70 ° arbitrarily angled adjustable below.After angle adjustment completes, carry out locked with cooperation pole 5 to it by the one-way cylinder 9 that guide rail installs additional.For the larger tunnel of part, lifting appliance can be equipped with in structural frame bottom, adjustment equipment level position.
