Description
Technical field:
The utility model relates to the steel that is used for building engineering field to be supported, and relates in particular to a kind of feel trim actuator that steel supports that is used to remove.
Background technology:
The foundation pit construction of underground structrue engineering all needs to adopt steel to support when excavation pit avoids cheating wall and caves in, existing steel supporting base end portion joint generally mostly is the form that active head adds gad, support brace pre axial force with special-purpose jack pair steel earlier during use, and then insert gad.When needs are removed the steel support, at first to use crane the jack of special use to be placed in the active head place of steel supporting base end portion, and then give special-purpose jack pressurization by hydraulic oil pump, it is a certain amount of to outer displacement to make that foundation pit enclosure structure produces, treat originally to insert the loosening back taking-up of the gad appearance gad that steel supports the termination, with the jack release and remove, last crane hangs away the steel of being removed and supports again.The steel of this structure supports easy construction, is widely used in the excavation of foundation pit supporting.Yet in real world applications, this steel supports and also exposes its unsurmountable shortcoming: this is supported in the demolishing process soil body outside the stressed and foundation ditch of foundation pit enclosure structure is all produced certain disturbance and influence, thereby influences the intensity of foundation pit enclosure structure; The steel supporting removal needs crane and operator to cooperatively interact in addition, and process is complicated and dangerous, thereby has time-consuming shortcoming.
The utility model content:
Technical problem to be solved in the utility model is to overcome existing steel to support the difficult defective of unloading, provide a kind of steel easy and simple to handle to support feel trim actuator, its unloading demolishing process is little to the disturbance on foundation pit enclosure structure and peripheral stratum, has advantage convenient, fast, that saving is artificial, safe and reliable and efficiency of construction is high.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of steel supports feel trim actuator, and it is a cam mechanism, is arranged between the end face and the active head of support of steel support, and its camshaft supports steel by cam surface when rotated and unloads.
Steel described in the utility model supports feel trim actuator and includes camshaft, camshaft stand, force-transmitting block, spacing hook plate and unloading push pedal; Described camshaft stand has base plate, and this base plate is fixed on the end face of steel support; Described camshaft is set up on the camshaft stand and can be around self axis rotation, and this camshaft has the cam surface that radially changes, and its axis normal is in steel adding of supporting, uninstall direction; But described force-transmitting block is an active type detachable member, and it is folded in the cam surface of camshaft and supports between the active head; An end of camshaft is fixed in described unloading push pedal, and it can pull the camshaft rotation; Described spacing hook plate is articulated on the end face that steel supports and can hooks the unloading push pedal with the lock tab wheel shaft.
Different with existing steel support feel trim actuator is, the utility model has used the principle of cam mechanism, with the camshaft axis perpendicular to steel adding of supporting, uninstall direction, make its cam surface along the position that this adds, uninstall direction is in the radial distance maximum during loading, and unloading the time only need the rotating cam axle can finish unloading quickly and easily.So not only easy and simple to handle, and unloading the time needn't make foundation pit enclosure structure produce to outer displacement, therefore the utlity model has following advantage:
1, simplifies existing steel and supported the operation that unloading is removed, thereby improved efficiency of construction.
2, the entire mechanism volume is less, but the repeated multiple times utilization.
3, unloading only needs the one man operation to get final product, and has saved artificial.
4, reduce to unload disturbance and influence to foundation pit enclosure structure and peripheral stratum.
Description of drawings:
Fig. 1 is a structure elevation of the present utility model.
Fig. 2 is a structure vertical view of the present utility model.
Fig. 3 is a structure side view of the present utility model.
The specific embodiment:
Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments.
Please comprehensively consult Fig. 1, Fig. 2 and Fig. 3 structure chart of the present utility model.Traditional steel support is made up of steel support 6 and active 7 of support, and it adds, uninstall direction is the vertical of edge support 6, the i.e. left and right directions of Fig. 1; It is a cam mechanism that the diagram steel supports feel trim actuator, and between it was arranged at the end face 61 of steel support 6 and supports active 7, the camshaft 1 of this cam mechanism supported 6 by 11 pairs of steel of its cam surface when rotated and unloads.
Described steel supports feel trim actuator and includes camshaft 1, camshaft stand 2, force-transmitting block 3, spacing hook plate 5 and unloading push pedal 4.Described camshaft stand 2 has a base plate 21, and this base plate 21 is fixed on the end face 61 of steel support 6, and base plate 21 is welded on the middle part of end face 61 in the present embodiment.Described camshaft 1 is set up on the camshaft stand 2, and it can be around the rotation of self axis, and this camshaft 1 has cam surface 11 (see figure 2)s that radially change, and its axis normal supports 6 add, uninstall direction in steel.Described unloading push pedal 4 is a strip member, the one end be fixed in an end of camshaft 1 and its vertically with camshaft 1 axis normal, thereby it can pull camshaft 1 around self axis rotation, unloads push pedal 4 in the present embodiment and is welded on the camshaft 1.Described spacing hook plate 5 is articulated on the end face 61 of steel support 6 by its base 51, this base 51 is weldingly fixed on the end face 61, this spacing hook plate 5 can be around its hinge turn, and can hook unloading push pedal 4 the other end 41 in the outer part, so that unloading push pedal 4 location, thereby lock tab wheel shaft 1 is with anti-rotation.But described force-transmitting block 3 is an active type detachable member, and between it was folded in the cam surface 11 of camshaft 1 and supports active 7, the support force that acts in the steel support 6 vertically can be delivered on the camshaft 1 by force-transmitting block 3 more equably through active 7.
The specific operation process that steel described in the utility model supports feel trim actuator is as follows: during loading, at first camshaft 1 being rotated to its cam surface 11 adds along steel support 6, uninstall direction is in the initial position of radial distance maximum, and hook the initial position of the end 41 of unloading push pedal 4 with lock tab wheel shaft 1 with spacing hook plate 5, between the cam surface 11 of active 6 of support and camshaft 1, put into force-transmitting block 3 then, install steel support 6 and load axial support power by traditional mode again, under this original state, camshaft 1 contacts and bears steel by cam surface 11 and force-transmitting block 3 and supports axial support power on 6.Need after excavation of foundation pit finishes treating unloading to remove steel supported 6 o'clock, elder generation is with spacing hook plate 5 turns and recess the end 41 that unloads push pedal 4, knock or pull unloading push pedal 4 again, thereby drive camshaft 1 rotation, along with cam surface 11 reducing gradually to the radial distance at camshaft 1 center, the axial support power that steel supports on 6 also can reduce until complete discharge gradually, is drawable force-transmitting block 3 at last, supports 6 unloading and dismounting thereby finish steel quickly and easily.
Use steel support feel trim actuator described in the utility model and can realize unloading quickly and easily and remove steel support 6, reached the effect that reduces to unload to the disturbance and the influence on foundation pit enclosure structure and peripheral stratum simultaneously.The utlity model has efficiency of construction height, time and labour saving and safe and reliable advantage.
