Description

Technical Field

[0001] This invention belongs to the field of tower crane anchoring technology, specifically a detachable tower crane anchoring device and its usage method. Background Technology

[0002] Tower cranes, also known as tower hoists, originated in Western Europe. They are rotating cranes with a jib mounted on the upper part of a tall tower. They offer a large working space and are mainly used for the vertical and horizontal transport of materials and the installation of building components in construction. They consist of three main parts: the metal structure, the working mechanism, and the electrical system. The metal structure includes the tower, the jib, and the base.

[0003] The tower crane anchoring device mainly consists of four parts: mounting base, mounting top, mounting column, and anchoring structure. As the building height increases, the tower crane will also become taller, but the stability of the tower crane cannot be guaranteed, so the tower crane anchoring device needs to be anchored to the main building.

[0004] However, the above technologies often have the following drawbacks: In traditional anchoring, the mounting base, mounting top, and mounting column are often connected to the wall by welding. At the same time, the indoor height of each building is different, and the height of the mounting base, mounting top, and mounting column needs to be prefabricated according to the indoor height. After construction, they need to be destructively removed. Fixed-length mounting bases, mounting tops, and mounting columns are not conducive to recycling and reuse.

[0005] Therefore, the present invention provides a detachable tower crane anchoring device and its method of use. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a detachable tower crane anchoring device of the present invention, comprising a load-bearing mechanism, a support mechanism, an installation mechanism and a connecting arm fixedly installed on the tower crane support, the connecting arm being connected to the tower crane by bolts.

[0008] The load-bearing mechanism includes assembly plates and connecting plates. Multiple assembly plates are provided, and two adjacent assembly plates are connected by bolts. The connecting plates are fixedly installed on the bottom surface of the assembly plates. The two ends of the assembly plates are provided with through holes for bolts to pass through, so as to facilitate the connection of two assembly plates. After the assembly plates are assembled, the connecting plates are fixed to the two ends by bolts.

[0009] The assembly plate is connected to the tower crane support via a connecting arm, thus connecting the assembly plate to the connecting arm. After the assembly plate is fixed to the building, it is used to anchor the tower crane.

[0010] The installation mechanism includes a support plate and a mounting platform. During installation, the support plate and the mounting platform are located on the upper and lower sides of the floor slab, respectively, and are connected by bolts. The mounting platform is rotatably connected to the connecting plate by a pin. By rotating the thread, the distance between the support plate and the mounting platform is adjusted, thereby fixing the support plate and the mounting platform. The connecting plate and the mounting platform are rotatably connected by a pin to fix the assembly plate to the wall.

[0011] The support mechanism includes a connecting ear plate, a support rod, and a support frame for pressing the connecting ear plate. The connecting ear plate is fixedly installed on the outer wall of the assembly plate, and the support frame is fixedly installed on the outer wall of the support rod. The connecting ear plate and the assembly plate are integrated. By holding the support rod and inserting the support frame into the inner wall of the connecting ear plate, the assembled plate is lifted up to facilitate connection with the ceiling.

[0012] Preferably, a force plate is detachably installed on the outer wall of the assembly plate, and an anti-slip pad is fixedly installed on the inner wall of the force plate. The side of the force plate away from the assembly plate is rotatably connected to the connecting arm. The anti-slip pad is a common rubber pad, which increases the friction between the force plate and the assembly plate.

[0013] Preferably, an mounting plate is provided on the side of the assembly plate away from the force plate. The mounting plate is connected to the force plate by bolts. A connecting rib is slidably inserted into the inner wall of the assembly plate. The rotating bolt clamps the assembly plate through the mounting plate and the force plate, thereby connecting the force plate and the assembly plate. The connecting rib is inserted into the two assembly plates respectively to achieve the initial connection of the assembly plates, so that the bolt holes can be aligned when the rotating bolt assembles the two assembly plates. Since this device is mostly used in construction with large machinery, the anti-slip pad can prevent the force plate from loosening due to vibration of the construction site.

[0014] Preferably, a threaded cylinder is installed on the outer wall of the support rod through internal and external thread engagement, and a support cylinder is rotatably installed on the bottom surface of the threaded cylinder. The axis of the support cylinder coincides with the axis of the threaded cylinder. A frustum structure that fits into the floor is provided on the bottom surface of the support cylinder. The end of the support rod away from the support frame extends into the inner cavity of the support cylinder and is slidably connected to the support cylinder. Rotating the threaded cylinder controls the raising and lowering of the support rod through threaded transmission.

[0015] Preferably, a protective steel cable is fixedly installed on the outer wall of the assembly plate, and a control piston is fixedly installed on the other end of the protective steel cable. A damping cylinder is slidably installed on the outer wall of the control piston. A receiving chamber for holding damping oil is provided in the inner cavity of the damping cylinder. A sealing ring is provided on the outer wall of the control piston and is sealed and fitted to the inner wall of the damping cylinder. A connecting shaft is provided at one end of the protective steel cable. The connecting shaft is slidably connected to the damping cylinder by a sealing method of a hydraulic cylinder moving rod. A connecting steel cable for binding the tower crane support is detachably installed on the outer wall of the damping cylinder. When the connection between the tower crane support and the connecting arm breaks, the control piston is forced to slide and compress the damping oil, thereby achieving a buffering effect. The protective steel cable and the connecting steel cable provide tension, improving the safety of use.

[0016] Preferably, the control piston has a through hole on its side wall for damping oil to pass through. When the control piston slides, the damping oil passes through the through hole to generate damping. There are elastically arranged blocking steel balls on both sides of the through hole. When the damping oil flows too fast, the blocking steel balls approach the through hole, reducing the flow diameter of the damping oil and thus reducing the sliding speed of the control piston. This keeps the control piston in a stable motion state, reducing the risk of breakage of the connecting steel cable and the protective steel cable. In the event of a breakage at the connection between the tower crane support and the connecting arm, the safety of use is further improved. A return spring is fixedly installed on the side wall of the control piston. The other end of the return spring is fixedly connected to the inner wall of the damping cylinder. After repairing the breakage, the return spring's elasticity drives the control piston to return to its original position.

[0017] Preferably, a mounting bracket is fixedly installed on the outer wall of the control piston, and a connecting rod is slidably installed on the inner wall of the mounting bracket. The mounting bracket provides space for the installation and sliding of the connecting rod. One end of the connecting rod is fixedly connected to the outer wall of the blocking steel ball. A connecting spring for pushing the connecting rod is fixedly installed on the outer wall of the mounting bracket. The elastic force of the connecting spring realizes the soft connection of the blocking steel ball, so as to limit the maximum sliding speed of the control piston.

[0018] Preferably, a detection end cap is fixedly installed on the outer wall of the protective steel cable. A sensing component is provided on the side wall of the detection end cap. The sensing component consists of a circuit board, a tension sensor, a logic controller, and a warning light. The tension sensor, logic controller, and warning light are all electrically connected to the circuit board. The pressure sensor is used to monitor the tension between the detection end cap and the outer wall of the damping cylinder. A connecting end cap is rotatably installed on one end of the connecting steel cable. The connecting end cap is connected to the damping cylinder through internal and external thread engagement to facilitate the connection between the connecting steel cable and the damping cylinder.

[0019] A method for auxiliary drainage in coal mine construction for water control, the method employing the aforementioned auxiliary drainage device for coal mine construction for water control, includes the following steps: A1. Measure the floor height and select the corresponding number of assembly plates. Make through holes in the ceiling and floor of the required floors for bolts to pass through. At the same time, install connecting arms on the tower crane support. A2. Insert the connecting ribs into the grooves on the inner wall of the assembly plate to complete the initial fixation between the two assembly plates. Fix the two adjacent assembly plates with bolts to complete the assembly of the assembly plates. A3. Fix the two sets of support plates and mounting platforms to the ceiling and floor respectively with bolts. Then install connecting plates at both ends of the assembled plate, and connect one of the connecting plates to the mounting platform located on the floor. A4. Lift up the assembled panel and insert the support frame into the connecting ear plate. Raise and adjust the support frame until the hole on the connecting plate on the other side is aligned with the mounting platform on the ceiling. Connect with bolts. A5. Secure the force plate and mounting plate to the outer wall of the assembly plate with bolts, and connect them to the force plate via connecting arms; A6. After binding one end of the connecting steel cable to the tower crane support, screw the connecting end cap into the damping cylinder to complete the installation.

[0020] The beneficial effects of this invention are as follows: 1. This invention uses an assembly plate, where two adjacent assembly plates are connected by bolts, and a connecting plate is fixedly installed on the bottom surface of the assembly plate. The assembly plate is rotatably connected to the mounting platform, allowing the assembled plate to be tilted between two floor slabs. This increases the upper limit of the force that the tower crane can bear when anchoring, improving safety. Multiple assembly plates can be assembled for use when anchoring the tower crane to bear the load. During construction, the plates can be divided into multiple pieces for transport, reducing construction difficulty. The plates are also adaptable to different indoor heights. After construction, the plates can be disassembled for easy recycling. 2. This invention, by setting up a control piston, damping cylinder, protective steel cable, and connecting steel cable, allows the control piston to slide and compress damping oil when the connection between the tower crane support and the connecting arm breaks. The damping oil generates damping through the through hole, thereby achieving a buffering effect. The protective steel cable and connecting steel cable provide tension, improving the safety of use.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] Example 1: As Figure 1-4 As shown in the embodiment of the present invention, a detachable tower crane anchoring device includes a load-bearing mechanism, a support mechanism, an installation mechanism, and a connecting arm 8 fixedly installed on the tower crane support. The connecting arm 8 is connected to the tower crane by bolts.

[0026] The load-bearing mechanism includes an assembly plate 1 and a connecting plate 7. Multiple assembly plates 1 are provided. Two adjacent assembly plates 1 are connected by bolts. The connecting plate 7 is fixedly installed on the bottom surface of the assembly plate 1. The two ends of the assembly plate 1 are provided with through holes for bolts to pass through, so as to facilitate the connection of two assembly plates 1. After the assembly plates 1 are assembled, the connecting plate 7 is fixed to both ends by bolts.

[0027] The assembly plate 1 is connected to the tower crane support via the connecting arm 8, thereby connecting the assembly plate 1 and the connecting arm 8. After the assembly plate 1 is fixed to the building, it is used to anchor the tower crane.

[0028] It is assembled by multiple assembly plates 1 for use in anchoring tower cranes to bear loads. During construction, it can be divided into multiple pieces for transport, reducing construction difficulty. After construction, it can be disassembled for easy recycling and reuse.

[0029] The installation mechanism includes a support plate 5 and a mounting platform 6. During installation, the support plate 5 and the mounting platform 6 are located on the upper and lower sides of the floor slab, respectively, and are connected by bolts. The mounting platform 6 is rotatably connected to the connecting plate 7 by a pin. By rotating the thread, the distance between the support plate 5 and the mounting platform 6 is adjusted, thereby fixing the support plate 5 and the mounting platform 6. The connecting plate 7 and the mounting platform 6 are rotatably connected by a pin to fix the assembly plate 1 to the wall.

[0030] By rotating the connecting plate 7 and the mounting platform 6, the assembled plate 1 can be tilted between two floor slabs. When anchoring the tower crane, the tension force from the tower crane on the assembled plate 1 can be decomposed into two components: one perpendicular to the outer wall of the assembled plate 1 and the other horizontal to the assembled plate 1. This reduces the vertical force on the assembled plate 1. In actual use, the main force causing the load-bearing beam to break is the vertical force, which can increase the upper limit of the force when anchoring the tower crane and improve the safety of use.

[0031] The support mechanism includes a connecting ear plate 10, a support rod 12, and a support frame 11 for pressing the connecting ear plate 10. The connecting ear plate 10 is fixedly installed on the outer wall of the assembly plate 1, and the support frame 11 is fixedly installed on the outer wall of the support rod 12. The connecting ear plate 10 and the assembly plate 1 are integrated. By holding the support rod 12 and inserting the support frame 11 into the inner wall of the connecting ear plate 10, the assembled assembly plate 1 is lifted to facilitate connection with the ceiling.

[0032] A force plate 15 is detachably installed on the outer wall of the assembly plate 1. An anti-slip pad 14 is fixedly installed on the inner wall of the force plate 15. The side of the force plate 15 away from the assembly plate 1 is rotatably connected to the connecting arm 8. The anti-slip pad 14 is a common rubber pad, which increases the friction between the force plate 15 and the assembly plate 1.

[0033] An mounting plate 2 is provided on the side of the assembly plate 1 away from the force plate 15. The mounting plate 2 is connected to the force plate 15 by bolts. A connecting rib 13 is slidably inserted into the inner wall of the assembly plate 1. The rotating bolt clamps the assembly plate 1 through the mounting plate 2 and the force plate 15 to achieve the connection between the force plate 15 and the assembly plate 1. The connecting rib 13 is inserted into the two assembly plates 1 respectively to achieve the initial connection of the assembly plates 1, so that the bolt holes can be aligned when the rotating bolt assembles the two assembly plates 1. Since the device is mostly used in large-scale mechanical construction, the anti-slip pad 14 can prevent the force plate 15 from loosening due to vibration of the construction site.

[0034] A threaded cylinder 16 is installed on the outer wall of the support rod 12 through internal and external thread engagement. A support cylinder 3 is rotatably installed on the bottom surface of the threaded cylinder 16. The axis of the support cylinder 3 coincides with the axis of the threaded cylinder 16. A frustum structure that fits into the floor is provided on the bottom surface of the support cylinder 3. The end of the support rod 12 away from the support frame 11 extends into the inner cavity of the support cylinder 3 and is slidably connected to the support cylinder 3. Rotating the threaded cylinder 16 controls the raising and lowering of the support rod 12 through threaded transmission.

[0035] When it is necessary to lift the assembly plate 1, the support frame 11 is inserted into the connecting ear plate 10, and the threaded cylinder 16 is rotated to control the support rod 12 and the support frame 11 to lift the assembled assembly plate 1 after assembly, until the hole on the connecting plate 7 on the other side is aligned with the mounting platform 6 located on the ceiling, so as to assist the connection located on the ceiling.

[0036] Example 2: Figure 5-6 As shown in Example 1, another embodiment of the present invention is as follows: A protective steel cable 17 is fixedly installed on the outer wall of the assembly plate 1. A control piston 22 is fixedly installed on the other end of the protective steel cable 17. A damping cylinder 19 is slidably installed on the outer wall of the control piston 22. A receiving chamber for holding damping oil is provided in the inner cavity of the damping cylinder 19. A sealing ring is provided on the outer wall of the control piston 22 and is sealed and fitted to the inner wall of the damping cylinder 19. A connecting shaft is provided at one end of the protective steel cable 17. The connecting shaft is slidably connected to the damping cylinder 19 by a sealing method using a hydraulic cylinder moving rod. A connecting steel cable 21 for binding the tower crane support is detachably installed on the outer wall of the damping cylinder 19. When the connection between the tower crane support and the connecting arm 8 breaks, the control piston 22 is forced to slide and compress the damping oil, thereby achieving a buffering effect. The protective steel cable 17 and the connecting steel cable 21 provide tension, improving the safety of use.

[0037] The control piston 22 has a through hole on its side wall for damping oil to pass through. When the control piston 22 slides, the damping oil passes through the through hole to generate damping. There are elastic blocking steel balls 9 on both sides of the through hole. When the damping oil flows too fast, the blocking steel balls 9 approach the through hole, reducing the flow diameter of the damping oil and thus reducing the sliding speed of the control piston 22. This keeps the control piston 22 in a stable motion state, reducing the risk of breakage of the connecting steel cable 21 and the protective steel cable 17. In the event of a breakage at the connection between the tower crane support and the connecting arm 8, the safety of use is further improved. A return spring 23 is fixedly installed on the side wall of the control piston 22. The other end of the return spring 23 is fixedly connected to the inner wall of the damping cylinder 19. After repairing the broken part, the elastic force of the return spring 23 drives the control piston 22 to return to its original position.

[0038] A mounting bracket 4 is fixedly installed on the outer wall of the control piston 22. A connecting rod 25 is slidably installed on the inner wall of the mounting bracket 4. The mounting bracket 4 provides installation and sliding space for the connecting rod 25. One end of the connecting rod 25 is fixedly connected to the outer wall of the blocking steel ball 9. A connecting spring 26 for pushing the connecting rod 25 is fixedly installed on the outer wall of the mounting bracket 4. The elastic force of the connecting spring 26 realizes the soft connection of the blocking steel ball 9, so as to limit the maximum sliding speed of the control piston 22.

[0039] A detection end cap 18 is fixedly installed on the outer wall of the protective steel cable 17. A sensing component 24 is provided on the side wall of the detection end cap 18. The sensing component 24 consists of a circuit board, a tension sensor, a logic controller, and a warning light. The tension sensor, logic controller, and warning light are all electrically connected to the circuit board. The pressure sensor is used to monitor the tension between the detection end cap 18 and the outer wall of the damping cylinder 19. A connecting end cap 20 is rotatably installed on one end of the connecting steel cable 21. The connecting end cap 20 is connected to the damping cylinder 19 through internal and external thread engagement to facilitate the connection between the connecting steel cable 21 and the damping cylinder 19.

[0040] After installation, in order to improve the service life of the protective steel cable 17 and the connecting steel cable 21, the protective steel cable 17 and the connecting steel cable 21 need to be in a slack state, that is, in a state where they are not under the tension of the tower crane. The tension is monitored by a tension sensor. When the tension exceeds the safe range, the logic controller controls the warning light to light up and alarm, so as to intuitively show the stress status of the protective steel cable 17 and the connecting steel cable 21. At the same time, when the connection between the tower crane support and the connecting arm 8 breaks, the protective steel cable 17 and the connecting steel cable 21 will be under stress, and the warning light will light up, so as to facilitate the inspection by the staff.

[0041] like Figure 7 As shown, a method for using a detachable tower crane anchoring device, the method employing the aforementioned detachable tower crane anchoring device, includes the following steps: A1. Measure the floor height and select the corresponding number of assembly plates 1. Make through holes in the ceiling and floor of the required floor for bolts to pass through. At the same time, install the connecting arm 8 on the tower crane support. A2. Insert the connecting rib 13 into the groove on the inner wall of the assembly plate 1 to complete the initial fixation between the two assembly plates 1. Fix the two adjacent assembly plates 1 with bolts to complete the assembly of the assembly plates 1. A3. Fix the two sets of bearing plates 5 and mounting platform 6 to the ceiling and floor respectively with bolts. Then install connecting plates 7 at both ends of the assembled assembly plate 1. One of the connecting plates 7 is connected to the mounting platform 6 located on the floor. A4. Lift up the assembled assembly plate 1 and insert the support frame 11 into the connecting ear plate 10. Raise and adjust the support frame 11 until the hole on the connecting plate 7 on the other side is aligned with the mounting platform 6 on the ceiling. Connect with bolts. A5. The force plate 15 and the mounting plate 2 are fixedly installed on the outer wall of the assembly plate 1 by bolts, and connected to the force plate 15 by the connecting arm 8. A6. After binding one end of the connecting steel cable 21 to the tower crane support, screw the connecting end cap 20 into the damping cylinder 19 to complete the installation.
