Problems solved by technology

During the use of the crane, the load of the crane’s rail-bearing beam will also be limited by the load of the workplace, especially in some special manufacturing workshops, the load of the rail-bearing beam is often limited by the load of different areas of the workplace, so if When a large-tonnage crane works in a small-tonnage area, it is easy to overload the rail bearing beam, so the work is very unsafe

Embodiment 1

[0044] figure 1 It is a schematic structural diagram of an overload detection device 10 provided in Embodiment 1 of the present invention. This embodiment can be applied to the working conditions of a crane 20, such as figure 1 As shown, the overload detection device 10 specifically includes: a trigger 101, a gear 102, and a load limiter 103; the load limiter 103 includes a controller 1031 and a gravity sensor 1032; the controller 1031 can be arranged inside the crane 20, so it can be used In phantom, the preferred controller 1031 is located in the console of the crane 20 .

[0045] The trigger 101 is arranged on a vertical plane at the junction of adjacent working areas; it is used for contacting the shifter 102 when the cart end beam 201 of the crane 20 moves to the junction.

[0046] Here, the trigger 101 can be arranged on the crane 20 that does not move, or on the cart rail of the crane, as long as it is on the vertical plane and can be in contact with the positioner 102...

Embodiment 2

[0076] Figure 10 It is a flowchart of an overload detection method provided by Embodiment 1 of the present invention. This embodiment is applicable to the working conditions of cranes. The method can be executed by an overload detection device, and specifically includes the following steps:

[0077] Step 301, acquire the current gear position of the gear shifter.

[0078] Wherein, the current gear is the gear where the current gear switch is located.

[0079] Step 302: Determine the working area where the crane is located according to the current gear position.

[0080] There is a one-to-one preset relationship between the gear position and the working range. In this way, according to the corresponding relationship, it is determined that the working area corresponding to the current gear position is the working area where the crane is located.

[0081] In this embodiment, the working site where the crane works includes at least two working areas, wherein the maximum load-b...

Embodiment 3

[0102] Figure 12 It is a schematic structural diagram of an overload detection device provided in Embodiment 1 of the present invention. This embodiment is applicable to the working conditions of cranes, and specifically includes:

[0103] The first acquiring module 401 is configured to acquire the current gear position of the gear shifter.

[0104] The determination module 402 is configured to determine the working area where the crane is located according to the current gear position.

[0105] The second acquiring module 403 is configured to acquire the load weight of the crane.

[0106] The control module 404 is configured to control the crane to stop when the weight of the load is greater than the preset maximum load capacity of the current working area.

[0107] In this embodiment, when the load weight is greater than the maximum load-bearing capacity of the working area, the controller controls the crane to stop. In this way, it can prevent the crane from still workin...

Abstract

The invention discloses an overload detection device and method and a storage medium. The overload detection device comprises a trigger, a gear position device and a load limiter, wherein the load limiter comprises a controller and a gravity sensor, and the trigger is arranged on a vertical plane at the junction of adjacent working areas; the gear position device is arranged on a crane end girderof a crane, and the gravity sensor is arranged on a main beam of the crane; and the gear position device and the gravity sensor are respectively connected with the controller. The crane end girder moves to the junction, the trigger contacts the gear position device, and the gear position device changes a gear. The controller determines the working area of the crane according to the current gear position of the gear position device. When load weight obtained by the gravity sensor is greater than the maximum bearing capacity of the working area, the controller controls the crane to stop. Thus, the overload detection device can prevent the crane from working after overload, thereby effectively preventing the overload phenomenon of a bearing-rail beam, and reducing the factors of crane dangerously working.

Description

technical field [0001] The embodiment of the present invention relates to a crane detection technology, in particular to an overload detection device, method and storage medium. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. During the use of the crane, the load of the crane's rail-bearing beam will also be limited by the load of the workplace, especially in some special manufacturing workshops, the load of the rail-bearing beam is often limited by the load of different areas of the workplace, so if When a large-tonnage crane works in a small-tonnage area, it is easy to overload the rail bearing beam, so the work is very unsafe. Contents of the invention [0003] The invention provides an overload detection device, method and storage medium, so as to prevent the occurrence of overload phenomenon. [0004] In the first aspect, an embodiment of the present ...
