Description
Technical field
The present invention relates to the tunneling shield technical field of construction, be specifically related to a kind of counterforce device.
Background technology
The shield structure is the special engineering machinery of tunnel piercing, and tunneling shield stepping counterforce device adopts pre-embedded steel slab at present, and welds the counter-force bracket on steel plate.The pre-embedded steel slab quantity that the method arranges is many, wastes material, and is subjected to the impact of welding quality, and the counter-force that bracket provides is unreliable, and fltting speed is slow, and plant equipment is numerous and diverse, and the operating personnel that need are many.
Summary of the invention
The present invention is directed to above-mentioned technical problem and improve, intend providing a kind of simple in structure, easy to operate, be easy to carry, but and Reusability, and the fast shield structure stepping counterforce device of fltting speed.
For reaching above-mentioned purpose, a kind of simple and easy portable shield structure stepping counterforce device provided by the invention, comprise that soffit is the blocks (1) on plane, and the below of described blocks (1) is provided with erection column (2) for inserting the preformed hole of ground (3); The middle part of the right side wall of described blocks (1) has the circular arc cutaway (1a) of downward-extension on axis, as the location contact surface of ground rod iron (7); On described circular arc cutaway (1a), have the dowel hole (1b) that axis horizontal is extended, as ground rod iron (7) is fixed on blocks (1); The upper left quarter of described blocks (1) has for the groove (1c) that advances jack (4) termination to stretch into, and this groove (1c) is slit into two installation journal stirrups (1d) that front and back are spaced by the upper left of blocks (1); Upper left quarter at described blocks (1) also has two circular holes (1e) that journal stirrup (1d) is installed of vertical perforation, for advancing jack (4) and the jointed shaft (5) of blocks (1) to pass through; At the top of blocks (1), be provided with lifting journal stirrup (1f).
Be preferably, the lifting journal stirrup (1f) of described blocks (1) be positioned at the counterforce device center of gravity directly over, counterforce device can not shake when guaranteeing to lift.
Further, the upper surface of described blocks (1) consists of a plane (1g) and an inclined plane (1h), and the right-hand member of plane (1g) is connected with the left end of inclined plane (1h), and the right-hand member of described inclined plane (1h) is lower than the left end of inclined plane (1h); The surface, front, rear, left and right of described blocks (1) is plane.By optimizing the structure of blocks, reduce the weight of whole counterforce device, save material, reduce manufacturing cost.
The erection column of counterforce device is inserted in the preformed hole of ground, the circular arc cutaway of counterforce device right-hand member contacts with the rod iron that inserts ground simultaneously, with alignment pin, counterforce device and rod iron are fixed together, the left end of counterforce device links together with advancing jack, makes to advance jack cylinder angle when advancing to change and meets the demands.When advancing jack cylinder to reach range need to regain oil cylinder, the lifting journal stirrup by the counterforce device top first hangs counterforce device the counterforce device preformed hole, and then regains oil cylinder.Avoid like this manually-operated, also improved greatly efficiency simultaneously.
The invention has the beneficial effects as follows: simple in structure, the operation easily laborsaving, easy to carry, but Reusability, construction cost is low, and fltting speed is fast.

Fig. 1 is front view of the present invention.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is stereogram one of the present invention.
Fig. 4 is stereogram two of the present invention.
Fig. 5 is Construction State figure of the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
Simple and easy portable shield structure stepping counterforce device as shown in Figure 1, mainly consist of blocks 1 and erection column 2 two parts, and blocks 1 and erection column 2 are wholely set.The soffit of blocks 1 is plane, guarantees that soffit and ground 3 fit together, thus the contact area on increase and ground 3.
In conjunction with Fig. 1---shown in Figure 5, erection column 2 is arranged on blocks 1 lower left for inserting the preformed hole on ground 3.The middle part of the right side wall of blocks 1 has the circular arc cutaway 1a of downward-extension on axis, as the location contact surface of ground rod iron 7.On circular arc cutaway 1a, have the dowel hole 1b that axis horizontal is extended, as ground rod iron 7 is fixed on blocks 1.The upper left quarter of blocks 1 has for the groove 1c that advances jack 4 terminations to stretch into, and this groove 1c is slit into two installation journal stirrup 1d that front and back are spaced by the upper left of blocks 1.Upper left quarter at blocks 1 also has two circular hole 1e that journal stirrup 1d is installed of vertical perforation, for advancing jack 4 and the jointed shaft 5 of blocks 1 to pass through.At the top of blocks 1, be provided with lifting journal stirrup 1f.
Preferably, the lifting journal stirrup 1f of blocks 1 be positioned at the counterforce device center of gravity directly over, counterforce device can not shake when guaranteeing to lift.
Further, the upper surface of blocks 1 consists of 1gHe Yi inclined plane, a plane 1h, and the right-hand member of plane 1g is connected with the left end of inclined plane 1h, and the right-hand member of inclined plane 1h is lower than the left end of inclined plane 1h; In addition, the front surface of blocks 1, rear surface are plane.
During use, the erection column 2 of counterforce device is inserted in the preformed hole on ground 3, the circular arc cutaway 1a of counterforce device right-hand member contacts with the rod iron 7 that inserts ground simultaneously.With alignment pin 6, counterforce device and rod iron 7 are fixed together, the left end of counterforce device links together with advancing jack 4, makes to advance jack 4 oil cylinders angle when advancing to change and meets the demands.When advancing jack 4 oil cylinders to reach range need to regain oil cylinder, the lifting journal stirrup 1f by the counterforce device top first hangs counterforce device the preformed hole on ground 3, and then regains oil cylinder.Avoid like this manually-operated, also improved widely efficiency simultaneously.
