Description

Technical Field

[0001] This utility model belongs to the field of tower crane protection technology, specifically relating to a tower crane protection device for building construction. Background Technology

[0002] Tower cranes, also known as tower hoists, originated in Western Europe. They are rotating cranes with a jib mounted on 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, jib, and base. The working mechanism comprises four parts: hoisting, luffing, slewing, and traveling. The electrical system includes motors, controllers, distribution cabinets, wiring, signaling, and lighting devices.

[0003] However, existing tower cranes often lack the function of monitoring tilt angle and supporting the sides of the tower crane. When the tower crane lifts an excessively heavy object, it is easy for the tower crane to tilt too much, which may cause it to fall and create danger. Therefore, there is an urgent need for a tower crane protection device for building construction to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a tower crane protection device for building construction, so as to solve the problem mentioned in the background art that existing tower cranes often do not have the function of monitoring the tilt angle and do not have the function of supporting the side of the tower crane.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tower crane protection device for building construction, comprising a tower crane base, a support structure, an inclination sensor, and a control console. The tower crane base has inclination sensors fixedly connected to its top left and right sides. The support structure comprises four components, each including a base. The base is rotatably connected to the cylinder of an electric push rod. The piston rod of the electric push rod is rotatably connected to the top end of a support rod. The bottom end of the support rod is rotatably connected to the base. A push plate is fixedly connected to the outer wall of the support rod. The electric push rod and the inclination sensor are electrically connected to the control console. The control console contains a PLC controller and an audible and visual alarm.

[0006] Preferably, the base is fixedly connected to both the front and rear sides by fixing plates, and the fixing plates are threadedly connected to fixing bolts.

[0007] Preferably, one end of hinge one is fixedly connected to the right end of the top of the base, and the other end of hinge one is fixedly connected to the cylinder of the electric push rod.

[0008] Preferably, the piston rod of the electric push rod is fixedly connected to one end of the second hinge, and the other end of the second hinge is fixedly connected to the top of the support rod.

[0009] Preferably, one end of hinge three is fixedly connected to the top left end of the base, and the other end of hinge three is fixedly connected to the bottom of the support rod.

[0010] Preferably, reinforcing ribs are fixedly connected to both the front and rear sides of the support rod, and a push plate is fixedly connected to the other end of the reinforcing ribs.

[0011] Preferably, both ends of the tilt sensor are fixedly connected to the outer wall of the tower crane base by two fixing bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This tower crane protection device for building construction is equipped with an inclination sensor and a control console. The inclination sensor monitors the inclination angle of the tower crane base. When the inclination angle of the tower crane base is too large, such as when the inclination is >0.5° or the pressure of the electric push rod exceeds the limit, the control console will issue an alarm through an internal audible and visual alarm. By using the inclination sensor and the control console together, not only can the inclination angle of the tower crane base be monitored, but an alarm can also be triggered when the inclination angle is too large, thus improving the safety during use.

[0014] 2. This tower crane protection device for building construction is equipped with a support structure. When the tower crane base is detected to be tilted, the control console drives the electric push rod to start, causing the piston rod of the electric push rod to push the support rod to move towards the center, causing the push plate to push the side of the tower crane base, thereby adjusting the tilt angle of the tower crane base and keeping the tower crane base vertical. The real-time tilt angle and leveling status are displayed on the display screen of the control console. The support structure can support the side of the tower crane base, thereby adjusting the tilt angle of the tower crane base and keeping the tower crane base vertical. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a tower crane protection device for building construction, comprising a tower crane base 1, a support structure 2, an inclination sensor 3, and a control console 4. The inclination sensors 3 are fixedly connected to the left and right sides of the top of the tower crane base 1. The support structure 2 has four components, each including a base 21. The base 21 is rotatably connected to the cylinder of an electric push rod 25. The piston rod of the electric push rod 25 is rotatably connected to the top end of a support rod 28. The bottom end of the support rod 28 is rotatably connected to the base 21. A push plate 29 is fixedly connected to the outer wall of the support rod 28. The support structure 2 can support the sides of the tower crane base 1, thereby adjusting the tilt angle of the tower crane base 1. The electric push rod 25 and the inclination sensors 3 are electrically connected to the control console 4. The control console 4 is equipped with a PLC controller and an audible and visual alarm. Through the combined use of the inclination sensors 3 and the control console 4, not only can the tilt angle of the tower crane base 1 be monitored, but an alarm can also be triggered when the tilt angle is too large.

[0023] Furthermore, fixing plates 22 are fixedly connected to both the front and rear sides of the base 21. Fixing plates 22 are threadedly connected to fixing bolts 23. The base 21 is fixed to the ground by fixing plates 22 and fixing bolts 23 to prevent the fixing plates 22 from sliding.

[0024] Furthermore, one end of hinge 24 is fixedly connected to the top right end of the base 21, and the other end of hinge 24 is fixedly connected to the cylinder of electric push rod 25. The electric push rod 25 can rotate relative to the base 21 through hinge 24 to prevent interference when the electric push rod 25 moves.

[0025] Furthermore, the piston rod of the electric push rod 25 is fixedly connected to one end of the hinge 26, and the other end of the hinge 26 is fixedly connected to the top of the support rod 28. The electric push rod 25 can rotate relative to the support rod 28 through the hinge 26 to prevent interference when the electric push rod 25 moves.

[0026] Furthermore, one end of hinge 27 is fixedly connected to the top left end of the base 21, and the other end of hinge 27 is fixedly connected to the bottom of support rod 28. The support rod 28 can rotate relative to the base 21 through hinge 27, so that electric push rod 25 pushes support rod 28 to move towards the middle, and push plate 29 pushes the side of tower crane base 1.

[0027] Furthermore, reinforcing ribs 210 are fixedly connected to both the front and rear sides of the support rod 28, and the other end of the reinforcing rib 210 is fixedly connected to the push plate 29. The reinforcing rib 210 can increase the support strength of the push plate 29 and improve safety and stability.

[0028] Furthermore, both ends of the tilt sensor 3 are fixedly connected to the outer wall of the tower crane base 1 by two fixing bolts 31. The tilt sensor 3 is fixed to the outer wall of the tower crane base 1 by fixing bolts 31, and the tilt angle of the tower crane base 1 is monitored by the tilt sensor 3.

[0029] Working principle:

[0030] During use, the tilt angle of the tower crane base 1 is monitored by the tilt sensor 3. When the tilt of the tower crane base 1 is detected, the control console 4 drives the electric push rod 25 to start, causing the piston rod of the electric push rod 25 to push the support rod 28 to move towards the center, causing the push plate 29 to push the side of the tower crane base 1, thereby adjusting the tilt angle of the tower crane base 1 and keeping the tower crane base 1 vertical. The real-time tilt angle and leveling status are displayed on the screen of the control console 4. The support structure 2 can support the side of the tower crane base 1, thereby adjusting the tilt angle of the tower crane base 1 and keeping the tower crane base 1 vertical. When the tilt angle of the tower crane base 1 is too large, when the tilt is >0.5° or the pressure of the electric push rod 25 exceeds the limit, the control console 4 will sound an alarm through the internal audible and visual alarm. Through the combined use of the tilt sensor 3 and the control console 4, not only can the tilt angle of the tower crane base 1 be monitored, but an alarm can also be triggered when the tilt angle is too large, improving the safety during use.
