The specific embodiment
For making the object of the invention, technical scheme and advantage clearer; To carry out clear, complete description to technical scheme of the present invention below; Based on the specific embodiment among the present invention; Those of ordinary skills are resulting all other embodiments under the prerequisite of not making creative work, the scope that all belongs to the present invention and protected.
Reinforce the truss chassis, comprise support body and many brace summer; Said support body is provided with a plurality of guiding devices that are used to guide said brace summer glide direction; Said brace summer all is located in the said guiding device; Every pair of said brace summer is the coaxial setting of level; Many axis to said brace summer are parallel to each other, and every said brace summer all is connected with and is used for pushing mechanism that said brace summer is promoted to the direction away from said support body along its length direction; The bottom of said support body is provided with and is used for the rail wheel that cooperates with track.
Can simultaneously offset with the hole wall of mid-board and middle pilot tunnel mid-board is carried out interim bracing reinforcement through stretching out brace summer like this, the back that finishes of waiting to construct only need remove pushing mechanism and is applied to thrust on the brace summer and just can makes and reinforce the truss chassis and realize separating with mid-board.Move to the position that the next one need reinforce temporarily through rail wheel along track afterwards and proceed to reinforce, a complete set of system can be repeatedly used, and can not cause waste, has practiced thrift cost.
In each embodiment of the present invention, as preferred version, said pushing mechanism is arranged between every pair of said brace summer; Comprise screw shell and leading screw; Said leading screw and said screw shell pass through threaded engagement; One end of said leading screw props up said brace summer.
The screw shell thrust that can provide stable, powerful that matches with leading screw promotes brace summer, makes it tightly prop up the hole wall in mid-board or Zhong Dao hole, and the combination of the two is tightr.In addition, this fit structure when operating, only need make produce relative rotation between screw shell and the leading screw just can, very easy to use.
During practical implementation, two said screw shells in the said pushing mechanism of two covers that every pair of said brace summer connected are wholely set; Two said leading screws stretch into the said screw shell that is wholely set by two ends respectively.
Every pair of suffered force localization of brace summer is distributed on the screw shell, reaches stress balance, the double thread sleeve carries out high strength structure and reinforces it is fixed on the support body again, can simplify production technology, practices thrift cost of manufacture.
In each embodiment of the present invention, as preferred version, the side that said brace summer closes on said leading screw is provided with blind hole; One end of said leading screw stretches into said blind hole and props up the bottom of said blind hole, and then props up said brace summer.
Leading screw need bear great active force in the practice of construction process, under this active force, is easy to make leading screw crooked even fracture if the deviation of directivity of the axis of leading screw and active force is excessive; And, an end of leading screw being limited in the blind hole through above-mentioned setting, the other end is limited in the screw shell.When construction, blind pore wall and thread bush barrel can produce restriction to moving radially of leading screw, and the active force of offsetting non axial direction guarantees leading screw all the time along its axially-movable, reduces its bending and the probability that fractures.
In each embodiment of the present invention, as preferred version, said guiding device is gathering sill or pilot hole.
These two kinds of structures all can play good guide effect, and structure is also fairly simple.
In each embodiment of the present invention, as preferred version, said support body comprises two two frameworks that are arranged side by side; Two said frameworks are spliced by many crossbeams and many vertical beams; Connect through tie-beam between two said frameworks; The length direction of said tie-beam is consistent with the length direction of said brace summer.
During practical implementation, said tie-beam and said guiding device are wholely set.
This structure can be simplified overall structure, effectively reduces cost of manufacture.
In each embodiment of the present invention,, also be provided with oblique reinforcement between said two frameworks as preferred version.
Can make connect between two frameworks more firm like this, for stronger defensive ability/resistance ability being arranged from oblique active force.
In each embodiment of the present invention, as preferred version, said support body is provided with and is used to drive the motor that said rail wheel rotates.
Can make like this and reinforce the truss chassis and move voluntarily, need not that other is vehicle towed, use convenient.
The present invention provide specific embodiment to describe below for better explaining.
