It is well known that derrick crane stock is a kind of for being arranged on crane lower section, the dress of crane support is carried out Put, be widely used during building constructions, workshop building, be also indispensable accessory in crane it One；Existing removable derrick crane stock includes middle frame and pedestal, and pedestal is arranged on the lower section of middle frame, the bottom of pedestal End is arranged in capital construction concrete layer, and middle frame is multigroup, and multigroup middle frame is longitudinally connected together；Needed when it is used Capital construction soil layer is first carried out into Concrete Filled and specification, in order to coordinate pedestal to carry out more stable connection；This removable tower Found in formula lifting crane climbing frame use, the support effect of its pedestal is poor, and reliability is used so as to have impact on.

Utility model content

In order to solve the above technical problems, the utility model provides a kind of fixed and support effect preferably, improve using reliable The removable derrick crane stock of property.

Removable derrick crane stock of the present utility model, including middle frame and pedestal, middle frame are multigroup and many Group middle frame is longitudinally connected together；The pedestal includes substrate, multigroup inserting column and multigroup groups of springs, and the top of multigroup inserting column is equal It is connected with the bottom of substrate, the inner side of multigroup groups of springs is connected with the lateral wall of inserting column, the outside of multigroup groups of springs is and base Build concrete layer contact；The pedestal also includes support column, limiting plate, left limit post, right limit post, left nut, right nut, a left side Spring and right spring, the bottom of the support column and substrate connection, the top of support column are connected with the bottom of middle frame, left limit The bottom of post and right limit post and substrate connection, is provided with left through hole, middle through hole and right through hole, the left side on the limiting plate Limited post top passes through left through hole, and right limit capital end passes through right through hole, and support column top passes through middle through hole, the left limit post External thread structure is provided with the top of right limit post, the left nut spiral shell is on left limit post, and left nut bottom With limiting plate tip contact, right nut spiral shell is on right limit post, and right nut bottom and limiting plate tip contact, the left side Spring housing is contacted mounted in left limit post outside, and left spring top with limiting plate bottom, and left spring bottom connects with substrate top Touch, the right spring housing is mounted in right limit post outside, and right spring top contacts with limiting plate bottom, right spring bottom end and base Plate tip contact.

Removable derrick crane stock of the present utility model, also including multigroup clamp, every group of card in multigroup clamp Plate is installed in one group of outside of groups of springs, and the outside of multigroup clamp contacts with capital construction concrete layer.

Removable derrick crane stock of the present utility model, also including upper terminal pad and lower terminal pad, the upper connection Disk is connected with middle frame bottom, and lower terminal pad bottom is connected with substrate top, the support column top and bottom respectively with upper company Connect disk and the connection of lower terminal pad.

The beneficial effects of the utility model are compared with prior art：By above-mentioned setting, can be carried out by support column Preferably connection, fixed effect is improved by limiting plate, higher using reliability, and by groups of springs and capital construction concrete layer Can further improve fixed effect.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is used to illustrate the utility model, but is not limited to scope of the present utility model.

As shown in figure 1, removable derrick crane stock of the present utility model, including middle frame 1 and pedestal, middle frame is It is multigroup, and multigroup middle frame is longitudinally connected together；Pedestal includes substrate 2, multigroup inserting column 3 and multigroup groups of springs 4, multigroup to insert The top of post is connected with the bottom of substrate, and the inner side of multigroup groups of springs is connected with the lateral wall of inserting column, multigroup groups of springs Outside contacts 5 with capital construction concrete layer；Pedestal also includes support column 6, limiting plate 7, left limit post 8, right limit post, left nut 9th, right nut, left spring 10 and right spring, the bottom of support column and substrate connection, the top of support column connect with the bottom of middle frame Connect, the bottom of left limit post and right limit post and substrate connection, is provided with left through hole, middle through hole and right through hole on limiting plate, Left limit capital end pass through left through hole, right limit capital end pass through right through hole, support column top pass through middle through hole, left limit post and The top of right limit post is provided with external thread structure, left nut spiral shell on left limit post, and left nut bottom with it is spacing Plate tip contact, right nut spiral shell is on right limit post, and right nut bottom and limiting plate tip contact, and left spring is sleeved on Left limit post outside, and left spring top contacts with limiting plate bottom, left spring bottom and substrate tip contact, right spring housing Mounted in right limit post outside, and right spring top contacts with limiting plate bottom, right spring bottom end and substrate tip contact；Pass through Above-mentioned setting, can preferably be connected by support column, and fixed effect is improved by limiting plate, higher using reliability, And fixed effect can further improve by groups of springs and capital construction concrete layer.
