Embodiment
With reference to the accompanying drawings and embodiments, the utility model is described in detail.
A kind of placing device of tower crane leg, referring to Fig. 1 and Fig. 2, including sets up the cement at the pre-buried place of tower crane leg separately
Pour the support base 1 of the surrounding in pond, support base 1 is equipped with four and is fixedly connected with the ground, support base 1 include bottom plate 102 and
Main body 104, is equipped with multiple clamping screws 103 on bottom plate 102 and support base 1 can be fixed on cement and pour 7 side of pond, this outer support
The first reinforcing rib 101 for preventing that support base 1 is subject to external force to be deformed is additionally provided between the main body 104 and bottom plate 102 of seat 1.
Referring to Fig. 1 and Fig. 3, each support base 1 is fixedly connected with the support plate 2 that oriented cement pours the extension of 7 center of pond, because
This share four pieces of support plates 2 to cement pour pond 7 center extend, the length of four pieces of support plates 2 is consistent, in addition support plate 2 with
It is equipped between support base 1 and is used for strengthening support plate 2 and the second reinforcing rib 21 of 1 structural soundness of support base.Four pieces of support plates 2 exist
One end away from connected support base 1 is equipped with a fixed frame 3, and fixed frame 3 is located at the center that cement pours pond 7,
Fixed frame 3 is connected with every piece of support plate 2 by being arranged on the regulating device 4 of in support plate 2 and one end away from support base 1,
Regulating device 4 includes the adjusting screw 41 being threadedly coupled with fixed frame 3 and driving adjusts the motor that screw 41 is rotated
42, motor 42 drives the rotation for adjusting screw 41, this external support board 2 with the shaft of motor 42 positioned at the lower section for adjusting screw 41
The upper position corresponding to motor 42 is rotatably connected to the flexural pivot 43 fixed with 42 bottom surface of motor, and regulating device 4 can be around flexural pivot
43 are rotated in a certain range, and can also be realized and be detachably connected by regulating device 4 between fixed frame 3 and support plate 2.
Referring to Fig. 3, fixed frame 3 according to practice of construction needs, be fixedly connected with respectively in 3 four corners of fixed frame vertically with
The locating rod 31 of fixed frame 3, the bar footpath of the side of the close fixed frame 3 of locating rod 31 is more than 8 mounting hole of tower crane leg in addition
Aperture, the bar footpath of side of the locating rod 31 away from fixed frame 3 is less than the aperture of the mounting hole of tower crane leg 8, so that locating rod 31
Side away from fixed frame 3 may pass through the mounting hole of tower crane leg 8, and side of the locating rod 31 away from fixed frame 3 is equipped with outer
Screw thread 32, can carry out it by the locking nut 33 being arranged in locating rod 31 when locating rod 31 is fixed with tower crane leg 8
It is locked.
