Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crane control, in particular to a key switch for a crane remote controller. Background Art
[0002] A crane is a machine that makes cyclic and intermittent movements and belongs to a type of lifting machinery. The basic structure of a crane includes a hoisting mechanism, a traveling mechanism, a luffing mechanism, a slewing mechanism, and a metal structure, etc. The hoisting mechanism is the basic working mechanism of the crane, mostly composed of a suspension system and a winch, and there are also those that lift heavy objects through a hydraulic system. The traveling mechanism is used for longitudinally horizontally transporting heavy objects or adjusting the working position of the crane, generally composed of a motor, a reducer, a brake, and wheels. The luffing mechanism is only equipped on jib-type cranes. When the jib is raised, the amplitude decreases, and when it is lowered, the amplitude increases, which is divided into balanced luffing and unbalanced luffing. The slewing mechanism is used to slewing the jib and is composed of a driving device and a slewing bearing device. The metal structure is the skeleton of the crane. The main load-bearing members such as the bridge, jib, and gantry can be box-shaped structures, truss structures, or web structures. Some can use steel profiles as support beams. When in use, the crane is often controlled remotely.
[0003] Although the existing remote control devices can control the crane, they can often be directly opened and used, which is likely to cause the remote control to be used by non-professionals, increasing the safety accidents of the crane. In order to ensure the safe use of the crane, a key switch for a crane remote controller is needed to solve the above problems. Summary of the Utility Model
[0004] The purpose of the embodiment of the utility model is to provide a key switch for a crane remote controller, aiming to solve the following problem: the existing remote control devices are likely to be used by non-professionals, resulting in an increase in the safety accidents of the crane.
[0005] The embodiment of the utility model is implemented as follows. A key switch for a crane remote controller includes: a lower cover and an upper cover. The lower cover is provided with a battery compartment, and the upper cover is provided with a through hole and a socket. Slots are provided on both sides of the socket opened on the upper cover. The lower cover and the upper cover are cooperatively arranged and can be assembled together; a circuit board, which is installed on the lower cover and is arranged between the lower cover and the upper cover. A key is arranged on the circuit board, and the key passes through the through hole opened on the upper cover; a switch knob, which passes through the lower cover and is connected to the circuit board, and is used to control the power on and off of the circuit board; a battery cover, which is cooperatively arranged at the battery compartment opened on the lower cover and is used to control the opening and closing of the battery compartment.
[0006] Preferably, it further includes: a key which can be inserted into the circuit board through the socket opened on the upper cover and is used to control the on-off of the connection between the battery in the battery compartment and the circuit board. Clamping blocks are fixedly arranged on both sides of the key, and the clamping blocks are arranged in cooperation with clamping grooves. When the key is inserted through the socket, the clamping blocks can be clamped into the clamping grooves to increase the insertion and extraction resistance of the key and prevent the key from falling off. A limiting plate for limiting the key is fixed on the upper cover, and the limiting plate is used to prevent the key from being inserted too much and being difficult to extract.
[0007] Preferably, it further includes: an antenna which passes through the lower cover and is connected to the circuit board and is used to send the instructions of the circuit board to the crane and receive the signals sent by the crane; a transparent lamp bead which is installed on the circuit board and passes through the upper cover and is used to give a light prompt for the working state of the key switch.
[0008] The key switch of the crane remote controller provided by the utility model adds a key to open or close on the basis of remote control. The key can be kept by professionals to prevent the remote control device from being used by non-professionals, ensuring the safety of the crane operation and having strong practicability.

[0013] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and do not limit the present utility model.
[0014] The following describes the specific implementation of the present utility model in detail with specific embodiments.
[0015] Please refer to Figure 1 and Figure 2 , a key switch of a crane remote controller provided by an embodiment of the present utility model, the key switch of the crane remote controller includes:
[0016] A lower cover 1 and an upper cover 2, the lower cover 1 is provided with a battery compartment, the upper cover 2 is provided with a through hole and a socket, and clamping grooves are provided on both sides of the socket opened on the upper cover 2. The lower cover 1 and the upper cover 2 are cooperatively arranged and can be assembled together; a circuit board 3, which is installed on the lower cover 1 and is arranged between the lower cover 1 and the upper cover 2. A key 4 is arranged on the circuit board 3, and the key 4 passes through the through hole opened on the upper cover 2; a switch knob 5, which passes through the lower cover 1 and is connected to the circuit board 3, is used to control the power on and off of the circuit board 3; a battery cover 6, which is cooperatively arranged at the battery compartment opened on the lower cover 1, is used to control the opening and closing of the battery compartment.
