Problems solved by technology

[0002] When the crane lifts the suspended object, the hook and the steel wire rope connected to the suspended object not only bear the weight of the suspended object itself but also bear the force generated by the acceleration process of the suspended object. The greater the acceleration, the greater the tension of the wire rope. When the traditional crane performs hoisting, since the electric hoist that pulls the wire rope runs at a constant speed, if the speed increases suddenly during the process of transporting goods, a large acceleration will be generated on the hoisted object, and the tension on the wire rope is very high. Large, the transportation process is very unstable, and even the suspended object has obvious shaking

Embodiment 1

[0030] Such as Figure 1-3 As shown, the first embodiment of the present invention provides a crane control method for controlling the crane 100, and the crane 100 is used for moving goods. The crane 100 includes a frame, a control module 10, a receiving module 11, a power module 01, a speed sensor and a load cell 04, wherein the receiving module 11, the power module 01, the speed sensor and the The load cells 04 are electrically connected to the control module 10 respectively, the power module 01 is installed on the frame, and the power module 01 is used to connect the goods to carry the goods. The crane control method includes the following steps:

[0031] S09, the receiving module 11 receives a control signal sent by the control device.

[0032] S10, the control module 10 acquires an expected conveying speed of the power module 01 for conveying the goods according to the control signal.

[0033] S11, the speed sensor acquires the real-time speed of the power module 01 carr...

Embodiment 2

[0060] Embodiment 2 of the present invention provides a crane 100 as described above.

[0061] In this embodiment, the control module 10 can reasonably calculate the acceleration and time required for the power module 01 to reach the expected transport speed according to the weight of the goods, and can ensure the acceleration process of the power module 01 smooth transport of the goods described in.

[0062] The serial numbers of the above embodiments of the present invention are for description only, and do not represent the advantages and disadvantages of the embodiments.

Abstract

The invention discloses a crane control method used for controlling a crane. The crane is used for carrying cargoes and comprises a rack, a control module, a receiving module, a power module, a speed sensor and a weighting sensor, wherein the receiving module, the power module, the speed sensor and the weighing sensor are electrically connected to the control module, and the power module is installed on the rack to carry the cargoes. The method comprises the steps that the control module acquires the expected carrying speed of the cargoes carried by the power module according to a control signal received by the receiving module; the control module calculates the accelerated speed and the movement time of the power module according to the carrying speed, the real-time speed, acquired by the speed sensor, of the cargoes carried by the power module and the weight, acquired by the weighing sensor, of the cargoes; the control module controls the power module to achieve the expected carrying speed according to the accelerated speed and the movement time of the power module. The invention further discloses the crane.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a crane and a control method for the crane. Background technique [0002] When the crane lifts the suspended object, the hook and the steel wire rope connected to the suspended object not only bear the gravity of the suspended object itself but also bear the force generated by the acceleration process of the suspended object. The greater the acceleration, the greater the tension of the steel wire rope. When the traditional crane performs hoisting, since the electric hoist that pulls the wire rope runs at a constant speed, if the speed increases suddenly during the transportation of goods, a large acceleration will be generated on the hoisted object, and the tension on the wire rope is very high. Large, the transportation process is very unstable, and even the suspended object has obvious shaking. Contents of the invention [0003] In order to solve the problems in the prior a...
