Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a composite tower crane foundation and a construction method thereof. Background Art

[0002] Tower crane, also known as tower crane, originated in Western Europe. It is a rotating crane with a boom mounted on the upper part of a tall tower. It has a large working space and is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. It consists of three parts: metal structure, working mechanism and electrical system. In cases where the construction site is small and the geological conditions are poor, steel lattice columns are combined with concrete foundations to form a composite structure to improve the stability and earthquake resistance of the tower crane foundation.

[0003] Tower cranes are generally fixedly installed on the foundation of the tower crane to ensure the stability of the tower crane. At present, most construction sites use cast-in-place concrete foundations, that is, a foundation pit is first dug at the location where the tower crane is required, a steel skeleton and pre-embedded anchor bolts are placed in the foundation pit, and then concrete is poured to form the foundation of the tower crane after solidification.

[0004] For the normal and safe use of tower cranes, the foundation is of paramount importance. In the construction of high-rise buildings and bridges and other projects that require high precision, accurate verticality is very important, so the horizontality of the tower crane is required to be very high. However, during the construction process, extreme weather such as strong winds and heavy rains, as well as insufficient foundation bearing or loose foundation soil, can easily cause the tower crane foundation to deflect. It is difficult for the naked eye to detect the slight deflection of the tower crane in time, which can easily lead to the project quality not meeting the requirements. Summary of the invention

[0014] Preferably, the bottom of the tower crane body is fixedly mounted on the top of the horizontal plate, and the internal threads of the support plate are mounted on the upper surface of the casting base.

[0015] The present invention also provides the following construction method of composite tower crane foundation: First, the bottom of the tower crane body is fixedly installed on the top of the horizontal plate. Then, when the tower crane foundation is in a horizontal state, the first spring is in a compressed state, so that the side wall of the four contact plates close to each other is pressed against the outer wall of the vertical ball, and the pressure threshold of the pressure sensor at the other end of the first spring is within a normal level. When the tower crane foundation deviates in one direction, the vertical gravity of the vertical ball is used to squeeze a certain contact plate, so that the squeezed contact plate will drive the first spring to further squeeze the pressure sensor, so that the pressure threshold of a certain pressure sensor is increased until it exceeds the threshold, so that the pressure sensor can be used to alarm and promptly remind the tower crane personnel to stop construction; The pressure sensor whose pressure threshold exceeds the threshold value transmits a signal to a certain electric push rod, controls the electric push rod to drive a certain lifting rod to rise, and when one of the contact plates is pressed, the contact plate in the opposite direction will move in the direction of the vertical ball under the elastic force of the first spring, so that the pressure threshold value of the opposite pressure sensor is reduced, and the opposite pressure sensor controls the electric push rod directly below to drive the lifting rod to descend, so that the rise and descent are carried out synchronously, and the verticality of the tower crane is quickly calibrated; When the pressure sensor alarms, the slide is used to drive the slide rod to move. When the pressure threshold of the pressure sensor exceeds or falls below the normal range during the sliding of the slide, the stop block will slide out of the second slide groove, and the reinforcement plate will move down and bring out multiple reinforcement rods to stop fixing the universal ball, so as to automatically unlock and disengage.

[0016] During the horizontal adjustment process, the slide plate will drive the block to move closer to the second slide slot. When the block slides into the second slide slot again, part of the reinforcement rod is driven by the third spring to fit into the partially aligned reinforcement hole to complete the reinforcement of the universal ball.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. When the tower crane foundation is offset, the vertical gravity of the vertical ball can be used to squeeze the contact plate, so that the slide plate uses the elastic force of the first spring to squeeze the pressure sensor. When a certain threshold is reached, the pressure sensor can be used to alarm, promptly reminding the tower crane personnel to stop construction, and transmit corresponding signals to control the electric push rod to move up and down. The lifting rod is used to adjust the horizontality of the horizontal plate until the pressure threshold of the pressure sensor returns to the normal level, so that the verticality of the tower crane can be quickly calibrated to ensure the quality of the project during construction.

[0018] 2. When the foundation of the tower crane is offset, after the pressure sensor sounds an alarm, the cooperation of the slide plate and the first connecting rod can be used to move the reinforcement plate down and stop fixing the universal ball, so as to facilitate the subsequent adjustment of the horizontal degree of the horizontal plate. At the same time, after the pressure threshold of the pressure sensor returns to the normal level, the second connecting rod and the ball bearing can be used to adapt to the adjusted distance between the horizontal plate and the support plate, and multiple reinforcement rods can be used to re-insert the reinforcement holes to complete the further fixation of the horizontal plate, thereby ensuring the stability of the tower crane after adjustment, and further ensuring the engineering quality during construction.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] For example, see Figure 1-6 The present invention provides a composite tower crane foundation, comprising a horizontal plate 1, a tower crane body 2, a seat tube 6, a support plate 12, and a casting base 13. The bottom center of the horizontal plate 1 is fixedly connected with a support column 4, and the bottom of the support column 4 is fixedly connected with a universal ball 5, and the outer wall of the universal ball 5 is spherically connected to the inner wall of the seat tube 6; A monitoring and adjusting mechanism 3 is provided at the top center of the horizontal plate 1 to monitor and warn the verticality of the tower crane foundation during the construction process, and to make timely horizontal adjustments when it deviates; Further, the monitoring and adjusting mechanism 3 includes a main shell 301, and the bottom of the main shell 301 is fixedly connected to the top center of the horizontal plate 1, a wire rope 302 is fixedly connected to the top center of the main shell 301, and the other end of the wire rope 302 is fixedly connected to a plumb ball 303, and movable rods 304 are equidistantly slidably connected inside the main shell 301, and one end of the four movable rods 304 close to each other is fixedly connected to a contact plate 305, and one side wall of the four contact plates 305 close to each other is pressed against the outer wall of the plumb ball 303; More specifically, in this embodiment, the bottom of the tower crane body 2 is first fixedly installed on the top of the horizontal plate 1, and then the bottom of the main housing 301 is fixedly connected to the top center of the horizontal plate 1, and the top center of the main housing 301 is fixedly connected with a wire rope 302, and the other end of the wire rope 302 is fixedly connected with a plumb ball 303, so that when the tower crane foundation is in a horizontal state, the plumb ball 303 naturally vertically downwards; Then, movable rods 304 are equidistantly slidably connected inside the main shell 301, and the end portions of the four movable rods 304 that are close to each other are fixedly connected to a contact plate 305, and the side walls of the four contact plates 305 that are close to each other are pressed against the outer wall of the vertical ball 303, and at the same time, the side walls of the four slide plates 306 that are far away from each other are fixedly connected to a first spring 308, and a pressure sensor 309 is fixedly installed on the inner wall of the auxiliary shell 307, and the other end of the first spring 308 is pressed against the detection surface of the pressure sensor 309, so that in a normal horizontal state, the first spring 308 is in a compressed state, so that the side walls of the four contact plates 305 that are close to each other are pressed against the outer wall of the vertical ball 303, and the pressure threshold of the pressure sensor 309 at the other end of the first spring 308 is within a normal level; When the tower crane foundation deviates in one direction, the vertical gravity of the vertical ball 303 is used to squeeze a certain contact plate 305, so that the squeezed contact plate 305 will drive the first spring 308 to further squeeze the pressure sensor 309, so that the pressure threshold of a certain pressure sensor 309 is increased until it exceeds the threshold, so that the pressure sensor 309 can be used to alarm and remind the tower crane personnel to stop construction in time to avoid the project quality not meeting the requirements due to deflection; Then, the four pressure sensors 309 correspond to the four electric push rods 311 directly below, respectively, so that the pressure sensor 309 that exceeds the pressure threshold transmits a signal to a certain electric push rod 311, and the electric push rod 311 is fixedly installed on the corresponding pressure sensor 309 through the top of the support plate 12, and the output rod at one end of the electric push rod 311 is fixedly connected to the lifting rod 312, and the top of the lifting rod 312 is hemispherical, and the top of the lifting rod 312 is in contact with the bottom of the horizontal plate 1, so as to control the electric push rod 311 to drive a certain lifting rod 312 to rise; Since the side wall of the four contact plates 305 close to each other is pressed against the outer wall of the vertical ball 303, when one of the contact plates 305 is pressed, the contact plate 305 in the opposite direction will move toward the vertical ball 303 under the elastic force of the first spring 308, so that the pressure threshold of the pressure sensor 309 in the opposite direction is reduced to be lower than the normal pressure threshold, so that the pressure sensor 309 in the opposite direction controls the electric push rod 311 directly below to drive the lifting rod 312 to descend, so that the ascending and descending are performed synchronously; When the lifting and lowering adjustment is performed in the two directions, since the vertical ball 303 moves in one direction, the resistance plates 305 in the other two directions will not move, so that the pressure thresholds of the pressure sensors 309 in the two directions are within the normal range; When the tower crane foundation deviates in multiple directions, that is, when two contact plates 305 are squeezed, the electric push rod 311 is used to control the lifting speed of the lifting rod 312 according to the size exceeding the threshold or falling below the threshold, so as to achieve the effect of horizontal adjustment; During the adjustment process, the horizontal plate 1 will be lifted and lowered in the direction opposite to the offset, even if the pressure thresholds of the four pressure sensors 309 return to the normal thresholds, and the slide plate 306 will return to the middle position of the inner wall of the through slot 310, so that the verticality of the tower crane can be quickly calibrated, ensuring the engineering quality during construction; By doing as above, when the tower crane foundation is offset, the vertical gravity of the vertical ball 303 can be used to squeeze the contact plate 305, so that the slide plate 306 can use the elastic force of the first spring 308 to squeeze the pressure sensor 309. When a certain threshold is reached, the pressure sensor 309 can be used to alarm, and the tower crane personnel can be reminded to stop construction in time, and the corresponding signal can be transmitted to control the electric push rod 311 to rise and fall, and the lifting rod 312 can be used to adjust the horizontality of the horizontal plate 1 until the pressure threshold of the pressure sensor 309 returns to the normal level, so that the verticality of the tower crane can be quickly calibrated to ensure the quality of the project during construction. Example

[0023] On the basis of the above embodiment, the inner wall of the seat tube 6 is provided with a reinforcement assembly 7 to connect and reinforce the universal ball 5 during the construction process, and automatically unlock and disengage when an alarm is sounded; Further, the reinforcement assembly 7 includes a reinforcement plate 701, and the outer wall of the reinforcement plate 701 fits and slides with the inner wall of the seat tube 6, the outer wall of the reinforcement plate 701 is symmetrically fixedly connected with a connecting block 702, the inner wall of the seat tube 6 is provided with a first slide groove 9 corresponding to the connecting block 702, and the outer wall of the connecting block 702 fits and slides with the inner wall of the first slide groove 9, the bottom of the connecting block 702 is fixedly connected with a second spring 703, and the other end of the second spring 703 is fixedly connected to the inner wall of the first slide groove 9; More specifically, in this embodiment, under normal conditions, the outer wall of the reinforcement plate 701 fits and slides with the inner wall of the seat tube 6, and the outer wall of the reinforcement plate 701 is symmetrically fixedly connected with the connecting block 702, and the inner wall of the seat tube 6 is provided with a first sliding groove 9 corresponding to the connecting block 702, and at the same time, the outer wall of the connecting block 702 fits and slides with the inner wall of the first sliding groove 9, and the bottom of the connecting block 702 is fixedly connected with the second spring 703, so that the top of the reinforcement plate 701 can be driven to fit with the lower outer wall of the universal ball 5 by the second spring 703, at this time, the inner wall of the groove 704 is equidistantly provided with a clamping groove 705, and the inner wall of the clamping groove 705 is fixedly connected with a third spring 706, and the other end of the third spring 706 is fixedly connected with a reinforcing rod 707, and at the same time, the lower outer wall of the universal ball 5 is provided with a reinforcing hole 11 corresponding to the reinforcing rod 707, so that the universal ball 5 can be restricted by the reinforcing rod 707; When the pressure sensor 309 gives an alarm, that is, when the slide plate 306 moves a certain distance so that the pressure threshold of the pressure sensor 309 exceeds or falls below the normal range, the upper surfaces of the four slide bars 711 are spherically connected with the ball bearings 710, and the outer walls of the ball bearings 710 are spherically connected with the second connecting rod 709, and the outer wall of the second connecting rod 709 is slidably connected with the first connecting rod 708, and at the same time, the top of the first connecting rod 708 passes through the movable groove 8 and the through groove 310 and is fixed to the bottom of the slide plate 306, so that the slide plate 306 can be used to drive the slide bar 711 to move, and a limiting groove 10 is formed through the outer wall of the seat tube 6 corresponding to the slide bar 711, and the two side walls of the slide bar 711 slide in contact with the inner wall of the limiting groove 10, thereby ensuring the stability of the slide bar 711 during movement; A fixing rod 713 is fixedly connected to the bottom center of the reinforcement plate 701, and a connecting frame 714 is fixedly connected to the bottom of the fixing rod 713, and a sliding rod 711 is fitted on the upper surface of the connecting frame 714, and a stop block 712 is fixedly connected to the bottom of the four sliding rods 711, and the bottom of the stop block 712 is inclined, and the outer wall of the stop block 712 is fitted and slid with the inner wall of the second slide groove 715, so that during the sliding process of the slide plate 306, that is, when the pressure threshold of the pressure sensor 309 exceeds or falls below the normal pressure threshold, the slide plate 306 is not pressed. When the slider 306 moves out of the normal range, the stopper 712 will be driven to gradually slide out of the second slide groove 715, and the inclined surface of the stopper 712 will be used to make the reinforcement plate 701 descend, so that the multiple reinforcement rods 707 will gradually slide out of the reinforcement hole 11. When the pressure threshold of the pressure sensor 309 exceeds or falls below the normal range during the sliding process of the slide plate 306, the stopper 712 will slide out of the second slide groove 715, even if the reinforcement plate 701 moves down and brings out the multiple reinforcement rods 707 to stop fixing the universal ball 5, the effect of automatic unlocking and disengagement is achieved; Similarly, during the adjustment process, the slide plate 306 will drive the stop block 712 to approach the second slide groove 715 again. When the stop block 712 slides into the second slide groove 715 again, the reinforcement rod 707 forms a telescopic structure with the clamping groove 705 through the third spring 706, so that part of the reinforcement rod 707 can be driven by the third spring 706 to clamp into the partially aligned reinforcement hole 11 to complete the reinforcement of the universal ball 5, thereby facilitating the adjustment of the horizontal degree of the horizontal plate 1 and ensuring the stability of the tower crane after adjustment. Furthermore, the top of the first connecting rod 708 passes through the movable groove 8 and the through groove 310 to be fixed to the bottom of the slide plate 306, and the second connecting rod 709 slides on the inner wall of the first connecting rod 708, and the second connecting rod 709 and the ball bearing 710 are used to adapt to the adjusted spacing between the horizontal plate 1 and the support plate 12, thereby ensuring stability during the adjustment process; By doing as above, when the foundation of the tower crane is offset, after the pressure sensor 309 sounds an alarm, the cooperation between the slide plate 306 and the first connecting rod 708 can be used to move the reinforcement plate 701 downward and stop fixing the universal ball 5, so as to facilitate the subsequent adjustment of the horizontal degree of the horizontal plate 1. At the same time, after the pressure threshold of the pressure sensor 309 returns to the normal level, the second connecting rod 709 and the ball 710 can be used to adapt to the adjusted spacing between the horizontal plate 1 and the support plate 12, and multiple reinforcement rods 707 can be used to re-insert the reinforcement holes 11 to complete further fixation of the horizontal plate 1, thereby ensuring the stability of the tower crane after adjustment, and further ensuring the quality of the project during construction.

[0024] Construction process: first, the bottom of the tower crane body 2 is fixedly installed on the top of the horizontal plate 1. Then, when the tower crane foundation is in a horizontal state, the first spring 308 is in a compressed state, so that the side wall of the four contact plates 305 close to each other is pressed against the outer wall of the vertical ball 303, and the pressure threshold of the pressure sensor 309 at the other end of the first spring 308 is within a normal level. When the tower crane foundation has a unidirectional deviation, the vertical gravity of the vertical ball 303 is used to squeeze a certain contact plate 305, so that the squeezed contact plate 305 will drive the first spring 308 to further squeeze the pressure sensor 309, so that the pressure threshold of a certain pressure sensor 309 is increased until it exceeds the threshold, so that the pressure sensor 309 can be used to alarm and remind the tower crane personnel to stop construction in time; At the same time, the pressure sensor 309 whose pressure threshold exceeds the threshold value transmits a signal to a certain electric push rod 311, and controls the electric push rod 311 to drive a certain lifting rod 312 to rise. When one of the contact plates 305 is pressed, the contact plate 305 in the opposite direction will move in the direction of the vertical ball 303 under the elastic force of the first spring 308, so that the pressure threshold value of the opposite pressure sensor 309 is reduced, and the opposite pressure sensor 309 controls the electric push rod 311 directly below to drive the lifting rod 312 to descend, so that the rise and descent are carried out synchronously, and the verticality of the tower crane is quickly calibrated; Then, when the pressure sensor 309 gives an alarm, the slide plate 306 can be used to drive the slide bar 711 to move. When the pressure threshold of the pressure sensor 309 exceeds or falls below the normal range during the sliding of the slide plate 306, the stop block 712 will slide out of the second slide groove 715, and the reinforcement plate 701 will move down and bring out multiple reinforcement rods 707 to stop fixing the universal ball 5, thereby achieving the effect of automatic unlocking and disengagement. Then, during the horizontal adjustment process, the slide plate 306 will drive the stop block 712 to move closer to the second slide groove 715. When the stop block 712 slides back into the second slide groove 715, part of the reinforcement rod 707 can be driven by the third spring 706 to engage in the partially aligned reinforcement hole 11 to complete the reinforcement of the universal ball 5.

9. The composite tower crane foundation according to claim 1, characterized in that: The bottom of the tower crane body (2) is fixedly mounted on the top of the horizontal plate (1), and the internal threads of the support plate (12) are mounted on the upper surface of the casting base (13).

10. The construction method of the composite tower crane foundation according to claim 8, characterized in that: The following steps are involved: Step 1: The bottom of the tower crane body (2) is fixedly mounted on the top of the horizontal plate (1); then, when the tower crane foundation is in a horizontal state, the first spring (308) is in a compressed state, so that the adjacent side walls of the four contact plates (305) are pressed against the outer wall of the vertical ball (303), and the pressure threshold of the pressure sensor (309) at the other end of the first spring (308) is within a normal level; when the tower crane foundation deviates in one direction, the vertical gravity of the vertical ball (303) is used to press a certain contact plate (305), so that the pressed contact plate (305) drives the first spring (308) to further press the pressure sensor (309), so that the pressure threshold of a certain pressure sensor (309) is increased until it exceeds the threshold, so that the pressure sensor (309) can be used to alarm and promptly remind tower crane personnel to stop construction; Step 2: The pressure sensor (309) whose pressure threshold exceeds the threshold value transmits a signal to a certain electric push rod (311), and controls the electric push rod (311) to drive a certain lifting rod (312) to rise. When one of the contact plates (305) is pressurized, the contact plate (305) in the opposite direction will move in the direction of the vertical ball (303) under the elastic force of the first spring (308), so that the pressure threshold value of the opposite pressure sensor (309) is reduced, and the opposite pressure sensor (309) controls the electric push rod (311) directly below to drive the lifting rod (312) to descend, so that the rise and descent are carried out synchronously, and the verticality of the tower crane is quickly calibrated; Step 3: When the pressure sensor (309) gives an alarm, the slide plate (306) is used to drive the slide bar (711) to move. When the pressure threshold of the pressure sensor (309) exceeds or falls below the normal range during the sliding of the slide plate (306), the stop block (712) will slide out of the second slide groove (715), and the reinforcement plate (701) will move downward and bring out a plurality of reinforcement rods (707) to stop fixing the universal ball (5), so as to automatically unlock and disengage. Step 4: During the horizontal adjustment process, the slide plate (306) drives the stop block (712) to move closer to the second slide groove (715). When the stop block (712) slides back into the second slide groove (715), part of the reinforcement rod (707) is driven by the third spring (706) to engage in the partially aligned reinforcement hole (11) to complete the reinforcement of the universal ball (5).
