Description

Technical Field

[0001] This application relates to the field of intelligent tower crane technology, and more particularly to a remote control intelligent tower crane device. 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 primarily used for the vertical and horizontal transport of materials and the installation of building components in construction. They consist of three parts: a metal structure, a working mechanism, and an electrical system. In power construction, tower cranes serve as crucial lifting equipment and are widely used in various construction scenarios.

[0003] Currently, traditional tower crane operation requires operators to work in the tower crane cab, which not only creates a harsh operating environment but also poses certain safety risks. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a remote control intelligent tower crane device, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a remote-controlled intelligent tower crane device, comprising a tower crane body, a base fixedly connected to the bottom of the tower crane body, four fixing mechanisms arranged in a ring around the tower crane body on the top of the base, a limit frame slidably connected inside the fixing mechanism, a support mechanism on the top of the limit frame, a boom fixedly connected to one side of the tower crane body, a drive mechanism inside the boom, a hoist slidably connected to the bottom of the boom, a hook at the bottom of the hoist, a detection mechanism between the hook and the hoist, the detection mechanism including a weight sensor fixedly connected to the hoist, the side of the weight sensor away from the hoist fixedly connected to the hook, a camera on one side of the boom, and a wind speed sensor fixedly connected to the top of the tower crane body.

[0006] In a preferred embodiment, the fixing mechanism includes a mounting frame, which is fixedly connected to the base. A limit rod is slidably connected inside the mounting frame, and a spring is sleeved on the outside of the limit rod, with the spring located inside the mounting frame.

[0007] By adopting the above technical solution, the mounting frame is limited by the mounting bracket, the limiting rod is supported by the spring, and the limiting rod is inserted into the inside of the limiting frame to connect the limiting frame and the mounting bracket, which can better connect the limiting frame and the mounting bracket.

[0008] In a preferred embodiment, the support mechanism includes a sleeve rod, which is rotatably connected to a limiting frame. A movable rod is slidably connected inside the sleeve rod, and a bolt is threaded inside the movable rod. A baffle is fixedly connected to one side of the movable rod.

[0009] By adopting the above technical solution, the moving rod is limited by the sleeve rod, and then the moving rod is moved inside the sleeve rod by pulling it. Then, the bolt is fixed by rotating the bolt through the sleeve rod and into the interior of the moving rod. Finally, the tower crane body is supported by the baffle, which can better support the tower crane body.

[0010] In a preferred embodiment, the sleeve rod has several through holes on its surface, which are evenly distributed on the surface of the sleeve rod and are adapted to the bolts.

[0011] By adopting the above technical solution, through the matching of the through hole and the bolt, and then by rotating the bolt to make the bolt pass through the sleeve and enter the interior of the moving rod to fix the moving rod, the moving rod can be better fixed.

[0012] In a preferred embodiment, the drive mechanism includes a fixed frame, which is fixedly connected to the boom. A motor is fixedly connected to one side of the fixed frame, and a first rotating rod is fixedly connected to the output end of the motor. A driving gear is fixedly connected to the surface of the first rotating rod, and a driven gear meshes with one side of the driving gear. A second rotating rod is fixedly connected inside the driven gear, and the second rotating rod is rotatably connected to the fixed frame. Steel cables are sleeved on the surfaces of both the first and second rotating rods.

[0013] By adopting the above technical solution, the output end of the motor rotates to drive the first rotating rod to rotate, which in turn drives the driving gear to rotate, which in turn drives the driven gear to rotate, which in turn drives the second rotating rod to rotate. The rotation of the first and second rotating rods is then used to wind up and unwind the steel cable, which allows the first and second rotating rods to rotate more effectively.

[0014] In a preferred embodiment, the crane is fixedly connected to a steel cable.

[0015] By adopting the above technical solution, and by using the winding and unwinding of the steel cable to move the crane on the surface of the boom, the crane can be moved more effectively on the surface of the boom.

[0016] In a preferred embodiment, a controller is fixedly connected to the surface of the tower crane body, and a wireless signal transmitter is fixedly connected to the top of the controller. The controller is electrically connected to the motor, the crane, and the wireless signal transmitter.

[0017] By adopting the above technical solution, the motor and crane can be switched on and off by a controller, and the operator can control the controller through a remote control system via a wireless signal transmitter, thus enabling better control of the motor and crane.

[0018] In a preferred embodiment, the surface of the tower crane body is provided with counterweights.

[0019] By adopting the above technical solution, counterweights are provided on the surface of the tower crane body, which increase the center of gravity of the tower crane and prevent it from overturning when lifting heavy objects. This can better prevent the tower crane from overturning when lifting heavy objects.

[0020] The beneficial effects of this application are:

[0021] 1. This remote-controlled intelligent tower crane device, by setting up a wind speed sensor, a camera, and a weight sensor, monitors the wind speed at the construction site in real time. When the wind speed exceeds a set threshold, the remote control system automatically stops the tower crane operation to avoid safety risks. The weight sensor monitors the weight of the load on the hook in real time to ensure the safety of the lifting operation. The camera monitors the movement path of the lifted object in real time, providing a dynamic perspective during the lifting process to help the operator judge whether there is a risk of collision. This avoids the problems of traditional remote-controlled intelligent tower crane devices, where the operator needs to operate the tower crane from the tower crane cab, which not only has a harsh operating environment but also poses certain safety risks, thus improving practicality.

[0022] 2. This remote-controlled intelligent tower crane device, by setting up a baffle, a sleeve, a moving rod, and bolts, limits the moving rod by using the sleeve, then pulls the moving rod to move it inside the sleeve, and then rotates the bolt to pass through the sleeve and enter the moving rod to fix it. Finally, the baffle supports the tower crane body. This avoids the problem of traditional remote-controlled intelligent tower crane devices being unable to adjust the length of the support rod supporting the tower crane body, thus improving practicality.

The mounting frame 51 limits the mounting frame 51, and the spring 52 supports the limit rod 53. The limit rod 53 is inserted into the inside of the limit frame 9 to connect the limit frame 9 and the mounting frame 51, which can better connect the limit frame 9 and the mounting frame 51.

[0030] Reference Figures 3-4 The top of the limiting frame 9 is provided with a support mechanism 4, which includes a sleeve rod 42. The sleeve rod 42 is rotatably connected to the limiting frame 9. A movable rod 43 is slidably connected inside the sleeve rod 42. A bolt 44 is threaded inside the movable rod 43. A baffle 41 is fixedly connected to one side of the movable rod 43. The movable rod 43 is limited by the sleeve rod 42. The movable rod 43 is moved inside the sleeve rod 42 by pulling it. The bolt 44 is then rotated to pass through the sleeve rod 42 and enter the movable rod 43 to fix it. The baffle 41 supports the tower crane body 1, which can better support the tower crane body 1.

[0031] Reference Figure 4The sleeve rod 42 has several through holes evenly distributed on its surface. The through holes are adapted to the bolts 44. By adapting the through holes to the bolts 44, and then rotating the bolts 44, the bolts 44 can pass through the sleeve rod 42 and enter the interior of the moving rod 43 to fix the moving rod 43, thus better fixing the moving rod 43.

[0032] Reference Figure 1 A boom 10 is fixedly connected to one side of the tower crane body 1. A drive mechanism 3 is provided inside the boom 10. A hoist 11 is slidably connected to the bottom of the boom 10. A hook 12 is provided at the bottom of the hoist 11. A detection mechanism 2 is provided between the hook 12 and the hoist 11.

A wind speed sensor 21 is fixedly connected to the top of the tower crane body 1.

[0033] Reference Figures 1-2 The drive mechanism 3 includes a fixed frame 31, which is fixedly connected to the boom 10. A motor 36 is fixedly connected to one side of the fixed frame 31. A first rotating rod 34 is fixedly connected to the output end of the motor 36. A drive gear 32 is fixedly connected to the surface of the first rotating rod 34. A driven gear 33 meshes with one side of the drive gear 32. A second rotating rod 35 is fixedly connected inside the driven gear 33. The second rotating rod 35 is rotatably connected to the fixed frame 31. Steel cables are sleeved on the surfaces of both the first rotating rod 34 and the second rotating rod 35.

The drive gear 32 then drives the driven gear 33 to rotate, which in turn drives the second rotating rod 35 to rotate. The rotation of the first rotating rod 34 and the second rotating rod 35 then allows for the winding and unwinding of the steel cable, thus enabling the first rotating rod 34 and the second rotating rod 35 to rotate more effectively.

[0034] Reference Figures 1-2 The crane 11 is fixedly connected to the steel cable; by the winding and unwinding of the steel cable, the crane 11 can be moved on the surface of the boom 10, which can make the crane 11 move on the surface of the boom 10 more effectively.

The controller 6 controls the switching of the motor 36 and the crane 11, and the wireless signal transmitter 7 allows the operator to control the controller 6 through the remote control system, which can better control the switching of the motor 36 and the crane 11.

[0036] Reference Figure 1 The surface of the tower crane body 1 is provided with a counterweight 8; by providing a counterweight 8 on the surface of the tower crane body 1, the center of gravity of the tower crane is increased by the counterweight 8, which prevents the tower crane from overturning when lifting heavy objects, and can better prevent the tower crane from overturning when lifting heavy objects.

[0037] Working principle: The mounting bracket 51 limits the position of the mounting frame 51, and the spring 52 supports the limiting rod 53. The limiting rod 53 is then inserted into the limiting frame 9 to connect the limiting frame 9 and the mounting bracket 51. The limiting frame 9 then limits the sleeve rod 42, which in turn limits the moving rod 43. Pulling the moving rod 43 causes it to move inside the sleeve rod 42. The rotating bolt 44 passes through the sleeve rod 42 and enters the moving rod 43 to fix it. The baffle 41 supports the tower crane body 1, providing better support. The output of the motor 36 drives the first rotating rod 34 to rotate, which in turn drives the drive gear 3. The crane 11 rotates on the surface of the boom 10, driven by the drive gear 32. The drive gear 33 then rotates, driving the second rotating rod 35 to rotate. The first rotating rod 34 and the second rotating rod 35 rotate to wind up and down the steel cable. The wind up and down of the steel cable causes the crane 11 to move on the surface of the boom 10. The wind speed sensor 21 monitors the wind speed at the construction site in real time. When the wind speed exceeds the set threshold, the remote control system will automatically stop the operation of the tower crane to avoid safety risks. The weight sensor 23 monitors the weight of the object on the hook in real time to ensure the safety of the hoisting operation. The camera 22 monitors the movement path of the hoisted object in real time to provide a dynamic perspective during the hoisting process, helping the operator to judge whether there is a risk of collision with the hoisted object.
