Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to an anti-slanting detection device for cranes. Background Art

[0002] The most important thing for cranes during operation is the operation specifications. However, during hoisting operations, due to the complexity of the construction environment, non-standard operations often lead to tilted and slanted hoisting. This may bring potential safety hazards and damage the machinery itself. Therefore, anti-slant monitoring devices are usually installed on tower cranes to timely monitor the tilt during the hoisting process, thereby ensuring the safety of the operation and the integrity of the machinery and equipment.

[0003] At present, the anti-tilt detection device of the crane in the related art usually only uses a single lifting rope for anti-tilt detection. However, in actual use, when a hook accessory with multiple times (for example, 4 times) is used in combination with a crane for cargo lifting, since the hook accessory has multiple lifting ropes, when the anti-tilt detection device for a single lifting rope is installed, the anti-tilt detection device may be cross-affected by other lifting ropes, resulting in spatial interference in the detection effect, thereby affecting the anti-tilt detection effect of the entire crane. Therefore, we need a crane anti-tilt detection device that can detect multiple lifting ropes at the same time. Utility Model Content

[0004] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] Therefore, the purpose of the utility model is to provide a crane anti-slant detection device, which can effectively detect the inclination of a single lifting rope or multiple lifting ropes, thereby improving the practicality and application scope of the device.

[0006] To achieve the above-mentioned purpose, the utility model proposes a crane anti-slanting detection device, comprising two mounting frames and a detection plate, wherein the two mounting frames are detachably arranged side by side on the crane boom, a box body is arranged on the mounting frame, the two box bodies are symmetrically arranged, an inner cavity is arranged inside the box body, an opening is arranged on one side of the inner cavity, an annular sensing sheet is arranged on the horizontal inner wall of the inner cavity, and a signal transmitter electrically connected to the annular sensing sheet is arranged on the box body; the detection plate is arranged horizontally, a plurality of notches for limiting the lifting rope of the crane are arranged side by side on one side of the detection plate, a buckling piece is arranged on the notch, two ends of the detection plate can be slidably entered into the corresponding inner cavity from the corresponding opening, and both ends of the detection plate are provided with accompanying parts, the accompanying parts and the centers of the plurality of notches are located on the same straight line, a striker corresponding to the sensing sheet is extended on a vertical side of the accompanying part, and the striker is arranged on the inner side of the corresponding annular sensing sheet.

[0007] The utility model of the crane anti-slant detection device can follow the movement of a single or multiple lifting ropes by using the detection plate, and its additional accompanying parts can move synchronously with the lifting ropes. At the same time, the striker cooperates with the annular sensor sheet to timely and effectively detect the tilt of the lifting ropes, thereby improving the practicability and application range of the device.

[0008] In addition, the crane anti-slant detection device proposed in the application may also have the following additional technical features:

DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0021] The following describes the anti-slanting detection device for cranes according to the embodiment of the utility model in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 4 As shown, the crane anti-slant tension detection device according to the embodiment of the utility model may include two mounting frames 10 and a detection plate 30 .

[0023] Among them, two mounting frames 10 are detachably arranged side by side on the crane boom, a box body 50 is arranged on the mounting frame 10, the two box bodies 50 are symmetrically arranged, an inner cavity 51 is arranged inside the box body 50, an opening 511 is arranged on one side of the inner cavity 51, an annular sensor sheet 52 is arranged on the horizontal inner wall of the inner cavity 51, and a signal transmitter 60 electrically connected to the annular sensor sheet 52 is arranged on the box body 50.

[0024] The detection plate 30 is arranged horizontally, and a plurality of notches 311 for limiting the lifting rope of the crane are arranged side by side on one side of the detection plate 30 , and buckling parts 312 are arranged on the notches 311 .

[0025] It is understandable that after the mounting bracket 10 is mounted on the crane boom, when the hoisting rope on the crane is hoisted, the hoisting rope can move in the notch 311 .

[0026] Both ends of the detection plate 30 can be slidably arranged from the corresponding openings 511 into the corresponding inner cavity 51, and both ends of the detection plate 30 are provided with accompanying parts 40, and the accompanying parts 40 and the centers of the plurality of notches 311 are located on the same straight line, and a striker 41 corresponding to the sensing sheet is extended from a vertical side of the accompanying part 40, and the striker 41 is arranged on the inner side of the corresponding annular sensing sheet 52.

[0027] It is understandable that the detection plate 30 can limit the position of a single or multiple hoisting ropes, and the hoisting ropes can drive the detection plate 30, the accompanying part 40 and the striker 41 to move together. When the tilt detection is performed on multiple hoisting ropes, the tilt conditions of multiple hoisting ropes can be monitored simultaneously, so as to more accurately evaluate the tilt state of the crane, ensure a comprehensive understanding of the tilt state of the entire crane, and improve the comprehensiveness and accuracy of the detection.

[0028] It should be noted that when the lifting rope is inclined, the striker 41 can be inclined with the lifting rope. If the striker 41 moves and contacts the annular sensor sheet 52, the annular sensor sheet 52 transmits the signal to the signal transmitter 60 for transmission. The signal transmitter 60 described in this embodiment can transmit the transmitted signal to the signal receiver. After receiving the signal from the signal receiver, the relevant personnel can quickly control the lifting work of the lifting rope to ensure the safety of the crane lifting. Therefore, the inclination of the lifting rope can be detected in a timely and effective manner, which improves the practicality and application scope of the device.

[0029] Specifically, in the actual process of anti-slant detection operation on the crane, the relevant personnel first install the mounting frame 10 on the crane boom. During the process, the notch 311 on the device is moved toward the direction of the lifting rope, and a single or multiple lifting ropes are allowed to enter the corresponding notch 311, and then the single or multiple lifting ropes are limited by the fastener 312 respectively. During the process, the lifting rope is in a vertical state.

[0030] After the device is installed, relevant personnel operate the crane to make the lifting rope lift the goods. During the process, if the lifting rope is tilted, the striker 41 can tilt with the lifting rope. If the striker 41 moves and contacts the annular sensor plate 52, the annular sensor plate 52 transmits the signal to the signal transmitter 60 for transmission. The signal transmitter 60 can transmit the transmitted signal to the signal receiver. After receiving the signal from the signal receiver, the relevant personnel can quickly control the lifting work of the lifting rope to ensure the safety of the crane lifting.

[0031] In one embodiment of the present invention, Figure 4 As shown, an elastic member 53 is horizontally arranged between the accompanying portion 40 and the inner cavity 51 .

[0032] It should be noted that the elastic member 53 described in this embodiment can be an annular rubber ring, a plurality of circumferentially distributed springs, etc. When the accompanying part 40 moves together with the detection plate 30, the elastic member 53 can provide a certain buffer for the accompanying part 40. At this time, the elastic member 53 can dissipate the tiny shaking force caused by the lifting rope being blown by a small amplitude by the wind, etc.

[0033] When the lifting rope is pulled obliquely, the striker 41 moves with the accompanying part and can contact the annular sensor plate 52. The annular sensor plate 52 transmits the signal to the signal transmitter 60 for transmission. After receiving the signal from the signal receiver, the relevant personnel can quickly control the lifting work of the lifting rope to ensure the safety of the crane lifting.

[0034] In one embodiment of the present invention, Figure 2 As shown, a connecting plate 20 is provided between the two mounting frames 10, and the connecting plate 20 is located on the side of the detection plate 30 away from the notch 311. It can be understood that the provided connecting plate 20 can increase the stability of the mounting frame 10, and the position of the connecting plate 20 does not affect the limiting position of the detection plate 30 on the lifting rope.

[0035] In one embodiment of the present invention, Figure 3-Figure 4 As shown, the longitudinal length of the accompanying portion 40 is greater than the longitudinal length of the opening 511. It can be understood that such a configuration can prevent the detection board 30 from being separated from the box body 50, thereby ensuring the installation and operation of the device.

[0036] Further, the detection plate 30 may include a middle portion 31 and an end portion 32 disposed between the middle portions 31, wherein the middle portion 31 and the end portion 32 are detachably disposed, the notch 311 is disposed on the middle portion 31, and the end portion 32 is disposed through the corresponding opening 511. It is understandable that such a configuration facilitates replacement of the middle portion 31 when a different number of notches 311 are required.

[0037] In summary, the crane anti-slant detection device of the utility model embodiment can follow the movement of a single or multiple lifting ropes by using the detection plate, and its additional accompanying parts can move synchronously with the lifting ropes. At the same time, the striker cooperates with the annular sensor sheet to timely and effectively detect the tilt of the lifting ropes, thereby improving the practicality and application scope of the device.
