Description

Technical Field

[0001] The utility model belongs to the technical field of tower crane balance bases, in particular to a tower crane pre-buried adjustable balance base. Background Art

[0002] Tower crane is the most commonly used lifting equipment on construction sites. It is also known as "tower crane". It is connected section by section and is used to lift raw materials for construction such as steel bars, wooden slats, concrete, steel pipes, etc. Tower crane is an indispensable equipment on the construction site. During the installation process of the tower crane, the tower crane needs to be fixed to ensure its stability.

[0003] In the current prior art, when pre-burying the base of the existing tower crane, it is necessary to first dig a pit on the ground for placing the base, put the supporting column of the base into the pit, and then pour cement mortar into the inside. After the cement mortar is bent and solidified, the tower crane base frame is placed on the top surface of the base. Since the cement mortar will show fluidity before solidification, after being placed in the base, the surrounding and bottom of the base cannot be effectively supported. As the cement mortar continues to solidify, it will cause a certain impact on the surface of the base, which will cause the base to tilt slightly. As the base frames on the top surface of the base are continuously superimposed and the height increases, the inclination angle of the base will increase with the increase in height, so that after the tower crane lifts the heavy object, the base frame at the bottom of the tower crane will collapse due to the uneven force of the heavy object.

[0004] To this end, the utility model provides a tower crane pre-embedded adjustable balancing base. Utility Model Content

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. For the adjustable balance base for tower crane pre-embedding of the present utility model, a support and limit platen is fixedly supported along the edge positions around the entrance of the deep pit, the L-shaped limit housing is sleeved on the docking limit block on the outer surface of the limit groove to limit the positions of the four groups of limit grooves, the tower crane base is suspended and placed into the deep pit by using a crane, the fitting anti-slip plate is extended and pushed in cooperation with the hydraulic rod, and the four fitting anti-slip plates will fit on the surrounding wall surfaces of the tower crane base, so that the tower crane base is suspended and lapped inside the deep pit, making the tower crane base supported vertically and horizontally upwards.

[0025] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0026] As Figures 1 to 6 shown, an adjustable balance base embedded in a tower crane according to an embodiment of the present utility model includes an earthen base layer 11 and a supporting and limiting platform plate 12 detachably installed on the top surface of the earthen base layer 11, a tower crane base 13 movably sleeved on the outer surfaces of the earthen base layer 11 and the supporting and limiting platform plate 12, an underframe 14 threadedly fixed and installed on the top surface of the tower crane base 13, a limiting groove 121 opened on the top surface of the supporting and limiting platform plate 12, a hydraulic rod 127 provided on the surface of the supporting and limiting platform plate 12 close to the underframe 14, a fitting anti-slip plate 128 fixedly connected to the output end of the hydraulic rod 127 and movably attached to the outer surface of the tower crane base 13, docking limiting blocks 129 fixedly connected to both side surfaces of the supporting and limiting platform plate 12, and an L-shaped limiting sleeve 1210 movably sleeved on the outer surface of the docking limiting block 129;

[0027] A support leg 135 is fixedly connected to the bottom surface of the tower crane base 13, a rectangular sleeve 136 is fixedly connected to the outer surface of the support leg 135, and an I-shaped anti-sway column 137 is fixedly connected to the outer surface of the rectangular sleeve 136;

[0028] A deep pit for storing the base is dug on the surface of the earthen base course 11. Support and limit platform plates 12 are fixed along the four peripheral edge positions at the entrance of the deep pit. The L-shaped limit sleeve 1210 is sleeved on the surface of the docking limit block 129 on the outer surface of the limit groove 121 to limit the positions of the four groups of limit grooves 121. The tower crane base 13 is suspended and placed into the interior of the deep pit by using a crane. In cooperation with the hydraulic rod 127, the fitting anti-slip plate 128 is extended and pushed. The four fitting anti-slip plates 128 will fit on the peripheral wall surfaces of the tower crane base 13, and then the tower crane base 13 is suspended and lapped inside the deep pit, so that the tower crane base 13 is supported vertically upward horizontally. The interior of the deep pit is filled with cement mortar by cooperating with a mud truck. At the same time, the contact area and range with the interior of the cement mortar are increased by cooperating with the support legs 135 and the I-shaped anti-sway columns 137 on the outer surface. As time goes by, the tower crane base 13 can be limited by the solidified cement at a vertical angle.

[0029] As Figures 1 to 5 shown, a hydraulic pump 122 is fixedly installed on the top surface of the support and limit platform plate 12. A hinge 126 is fixedly connected to the output end of the hydraulic pump 122. A return pull rod 125 is movably sleeved at one end of the hinge 126. A push arm rod 123 is movably sleeved on the inner wall surface of the limit groove 121. Both ends of the return pull rod 125 are movably sleeved on the surface of one end of the push arm rod 123. A clamping lock 124 is arranged at one end of the push arm rod 123, and the other end of the clamping lock 124 is movably sleeved on the outer surface of the chassis 14. Bolts 131 are fixedly connected to the top surface of the tower crane base 13 and at the four corner positions. A rectangular socket ring 132 is movably sleeved on the outer surface of the bolt 131. A backing plate 133 is fixedly connected to the outer surface of the rectangular socket ring 132. A wear-resistant pad 134 is movably sleeved on the outer surface of the bolt 131 and the top surface of the backing plate 133;

[0030] After the tower crane base 13 is completely fixed on the surface of the cement block, cooperate with the wear-resistant pad 134, the chassis 14 and the rectangular socket ring 132 on the outer surface of the backing plate 133 to be sleeved on the surface of the bolt 131, and then fix it by screwing and sleeving the protruding bolt 131 on the top surface of the bolt chassis 14. Later, as the chassis 14 is continuously stacked and raised, one end of the push boom 123 is sleeved on the surface of the chassis 14, and the other end of the push boom 123 is limited to be sleeved inside the limit groove 121 for position limitation. Then, the return pull rod 125 is sleeved on one end surface of the push boom 123, and cooperate with the hydraulic pump 122 to pull the return pull rod 125 at one end of the hinge 126 towards the chassis 14. When the return pull rod 125 moves, it will push the push boom 123 to swing and adjust the height of the chassis 14. Then, the position of the moving push boom 123 is limited by the limit groove 121, so that when the push boom 123 moves inside the limit groove 121, it will not shake too much because there is no limitation on both sides of the push boom 123 when the push boom 123 pushes the chassis 14, achieving the effect of supporting the continuously raised chassis 14 in four directions, and avoiding that as the chassis 14 is continuously stacked, the chassis 14 will shake due to the swing of the wind, resulting in the bending of the connection between the chassis 14 and the tower crane base 13, and even the bolt falling off at the connection between the chassis 14 and the bolt 131.

[0031] As Figures 1 to 4 shown, grooves a1 are provided at the bottom edges on both sides of the support and limit table plate 12. Swing arm plates a2 are swing-connected to the inner side wall surfaces of the grooves a1. A triangular pyramid thorn a3 that is movably sleeved on the outer surface of the top of the earth base layer 11 is fixedly connected to the bottom surface of the swing arm plate a2. A threaded push rod a4 is threadedly movably sleeved on the top surface of the support and limit table plate 12, and one end of the threaded push rod a4 is movably lapped on the top surface of the swing arm plate a2;

[0032] Place the support and limit table plate 12 on the top surface of the earth base layer 11, cooperate with the threaded push rod a4 to rotate and press down on the surface of the support and limit table plate 12, and then use the threaded push rod a4 to press and push the swing arm plate a2, so as to compress the triangular pyramid thorn a3 on the bottom surface of the swing arm plate a2 into the earth base layer 11, thereby limiting the position of the support and limit table plate 12.

[0033] Working principle: A deep pit for storing the base is dug on the surface of the earthen base course 11. The supporting and limiting platform plate 12 is fixed along the four peripheral edge positions at the entrance of the deep pit. The threaded pressing rod a4 rotates and presses down on the surface of the supporting and limiting platform plate 12, and then the threaded pressing rod a4 presses and pushes the swing arm plate a2, thereby compressing the triangular cone spikes a3 on the bottom surface of the swing arm plate a2 into the inside of the earthen base course 11, thereby limiting the position of the supporting and limiting platform plate 12. The L-shaped limiting sleeve 1210 is sleeved on the surface of the docking limiting block 129 on the outer surface of the limiting groove 121 to limit the positions of the four groups of limiting grooves 121. The tower crane base 13 is suspended into the deep pit by a crane. The hydraulic rod 127 is used to extend and push the fitting anti-slip plate 128, and the four fitting anti-slip plates 128 will fit on the peripheral wall surfaces of the tower crane base 13, thereby suspending and lapping the tower crane base 13 in the deep pit, so that the tower crane base 13 is supported horizontally and vertically upward. The slurry truck is used to pour cement mortar into the deep pit. At the same time, the support legs 135 and the I-shaped anti-sway columns 137 on the outer surface are used to increase the contact area and range with the inside of the cement mortar. As time goes by, the tower crane base 13 can be limited by the solidified cement at a vertical angle;

[0034] After the tower crane base 13 is completely fixed on the surface of the cement block, the wear-resistant pad 134, the chassis 14 and the rectangular socket ring 132 on the outer surface of the backing plate 133 are sleeved on the surface of the bolt 131, and then the bolt 131 protruding from the top surface of the bolt chassis 14 is used for threaded socket fixing. Later, as the chassis 14 is continuously stacked and raised, one end of the push arm rod 123 is sleeved on the surface of the chassis 14, and the other end of the push arm rod 123 is limited and sleeved inside the limiting groove 121 for position limitation. Then the return pull rod 125 is sleeved on the surface of one end of the push arm rod 123. The hydraulic pump 122 is used to pull the return pull rod 125 at one end of the hinge 126 towards the chassis 14. When the return pull rod 125 moves, it will push the push arm rod 123 to swing and adjust the height of the chassis 14. Then the position of the moving push arm rod 123 is limited by the limiting groove 121, so that when the push arm rod 123 moves inside the limiting groove 121, it will not shake too much when the push arm rod 123 pushes the chassis 14 because there is no limitation on both sides of the push arm rod 123, achieving the effect of supporting the continuously raised chassis 14 in four directions.
