[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0022] Example

[0023] See also Figure 1 to Figure 7 In this embodiment, a device for controlling an oblique and crooked lifting is provided, which includes a crane traveling crane 1 and a wire rope 2. The wire rope 2 is installed at the lower end of the crane traveling crane 1, and a lifting hook is arranged at the bottom of the wire rope 2. When in use, the object to be lifted is hooked by the lifting hook, and then the crane is started, which drives the wire rope 2 to move, and then pulls the object on the lifting hook to move it and re-place it;

[0024] During lifting, if the lifting hook and the object on the ground are not in a vertical state, that is, 90° is formed, it is possible to cause oblique lifting, thereby causing accidents, equipment damage, etc. Based on this, in the utility model, an extension 4 is also provided at the lower end of the crane traveling crane 1, and the extension 4 is set on the outside of the wire rope 2. The extension 4 can trigger a safety warning when the wire rope 2 is skewed, thereby reminding the lifting personnel to avoid losses;

[0025] At the same time, the extension 4 is connected to the main unit 6 through the signal cable 5 to realize the transmission of the warning signal. The main unit 6 is installed in the cab of the crane, which is convenient for the hoisting operator to observe and operate. The main unit 6 has the function of one-key zeroing and setting the tilt alarm angle, and can display the tilt angle in real time. A touch LCD screen 61 is provided on the front side of the main unit 6. The touch LCD screen 61 is a touch screen, which can set the tilt angle through the touch LCD screen 61. A plurality of control buttons 62 are also provided at the front end of the main unit 6 below the touch LCD screen 61. The control buttons 62 are respectively an on / off button, an alarm signal pause button, and a one-key zeroing button. A plurality of aviation plugs are provided at the bottom of the main unit 6 as a starting power connection, an alarm or power-off output signal and a connection with the main control device of the crane, and a signal transmission with the extension 4. An alarm light is also installed on the top of the main unit 6 for prompting a warning, and can emit an audible and visual alarm.

[0026] The extension 4 is controlled by the above-mentioned buttons. Initially, the extension 4 may be tilted. You only need to press the one-touch zeroing button of the host 6. The default tilting angle of the current state is 0. The operation is convenient. After zeroing, the tilting angle of the wire rope 2 can be set through the touch LCD screen 61. The host 6 will sound and light alarm or cut off the power supply when it tilts to the set angle.

[0027] Specifically, the extension 4 includes a sleeve 1 41 and a sleeve 2 42. The cross sections of the sleeve 1 41 and the sleeve 2 42 are both semicircular structures, which are combined together to form a cylindrical structure with a hollow interior, and then the two can cover the wire rope 2 after being matched and installed. The tops of the sleeve 1 41 and the sleeve 2 42 are both provided with hanging ears 46, and the hanging ears 46 are provided with a product installation wire rope 43. The top of the product installation wire rope 43 is connected to the crane traveling crane 1, thereby realizing the installation and fixation of the entire extension 4;

[0028] A horizontal block 44 is provided on the outer wall of the sleeve 41, and a sensor 45 is installed on the horizontal block 44. When the sleeve 41 is skewed (skewed after zeroing), the sensor 45 can detect that the sleeve 41 is skewed. The sensor 45 is connected to the host 6 through the signal cable 5, and then transmits the signal to the host 6, which plays a warning role;

[0029] One side of the connection between sleeve 1 41 and sleeve 2 42 is hinged by hinge 47, and the other side is provided with lock 48. When in use, lock 48 is opened, so that sleeve 1 41 and sleeve 2 42 can be opened with hinge 47 as the axis, and then the steel wire rope 2 is put into extension 4 to complete the installation. Otherwise, it can be taken out.

[0030] The crane starts, the driver lowers the lifting hook and lifts the objects. The ground personnel attach the objects to the hook for lifting. The lifting hook and the objects on the ground do not form a vertical lifting condition. At the beginning of lifting, the wire rope 2 of the lifting hook forms an angle with the ground. At this time, this product starts to sound and light alarms or cut off the power supply to ensure the safety of personnel and equipment.

[0031] The utility model sets an extension unit 4 on the outside of the wire rope 2, and utilizes the detection function of the sensor 45. After the lifting angle is offset, it transmits a signal to the main unit 6 in the cab, so as to provide safety reminders and warnings to the lifting personnel, reminding them that the current operation is not standardized, and correcting their operation to avoid oblique lifting, accidents and equipment damage.

[0032] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
