Say further, said adjustment device comprise base plate, the gripper shoe that is parallel to each other and be located at base plate and gripper shoe between elevating mechanism; Said elevating mechanism comprises screw rod, is threaded in nut and tubular part on the screw rod, and the bottom of screw rod is vertically fixed on the end face of base plate, and the upper end is plugged on the inner chamber of tubular part; The top of tubular part is vertically fixed on the bottom surface of gripper shoe, and the bottom of tubular part holds out against the upper surface of nut.
Further say:
The thickness sum of the thickness of said base plate, the length of screw rod and gripper shoe is smaller or equal to the degree of depth of groove; The thickness sum of the thickness of said base plate, the length of screw rod, tubular part and gripper shoe is greater than the degree of depth of groove.
Be provided with four groups of elevating mechanisms between said base plate and the gripper shoe.
Owing to adopted technique scheme; Compared with prior art; The utility model all is provided with at the top of transition piece and extremity piece can hold the adjustment device that is used to regulate the tower crane degree of balance, reconciles bascule through this, can regulate the degree of balance of tower crane easily; The imbalance that customer service causes to tower crane because of geographical conditions or construction reason is for the construction safety in later stage provides safeguard.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Description of drawings
Fig. 1 is the plan structure sketch map of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of adjustment device described in the embodiment of the utility model.
The specific embodiment
Embodiment:
A kind of column foot basis that can regulate the tower crane degree of balance, as shown in Figure 1, comprise the central part 1, transition piece 2 and the extremity piece 3 that adopt prefabricated concrete to form.Central part 1 is cross, and its four end face outsides are respectively equipped with a transition piece 2, and the outside of transition piece 2 correspondence respectively is provided with an extremity piece 3.Central part 1, transition piece 2 and extremity piece 3 connect through some steel strand 4, and steel strand 4 run through the connection holes of reserving in central part 1, transition piece 2 and the extremity piece 3, and behind force-extension, two ends are fastening through securing member 5 respectively.All be provided with balancing weight 6 between two adjacent extremity pieces, the two ends of balancing weight 6 are pressed in respectively on the flange of two extremity piece bottoms.
The top of said transition piece 2 and extremity piece 3 is respectively equipped with groove 21,31, all can hold the adjustment device that is used to regulate the tower crane degree of balance in the groove 21,31.Groove 21,31 laterally runs through transition piece 2 and extremity piece 3 respectively.
As shown in Figure 2, the adjustment device comprise gripper shoe 201, the base plate 202 that is parallel to each other and be located at gripper shoe 201 and base plate 202 between elevating mechanism.Said elevating mechanism comprises screw rod 205, is threaded in nut 204 and tubular part 203 on the screw rod 205.Tubular part 203 can adopt steel pipe, and its internal diameter is slightly larger than the external diameter of screw rod 205, and external diameter is smaller or equal to the external diameter of nut 204.The bottom of screw rod 205 is vertically fixed on the end face of base plate 202, and the upper end is plugged on the inner chamber of 203 of tubes.The top of tubular part 203 is vertically fixed on the bottom surface of gripper shoe 201, and the bottom of tubular part 203 holds out against the upper surface of nut 204.The thickness sum of the length of the thickness of said base plate 202, screw rod 205 and gripper shoe 201 is smaller or equal to the degree of depth of groove 21,31.The thickness sum of the length of the thickness of said base plate 202, screw rod 205, tubular part 203 and gripper shoe 201 is greater than the degree of depth of groove 21,31.
