Problems solved by technology

[0003] Before the present invention, the conventional traveling trolley of the portal crane did not have the function of distance measurement and anti-collision. During the operation, two portal cranes on the same track would run opposite each other or collide with each other when the cranes were running near the car stop. danger

Embodiment Construction

[0017] see figure 1 , The present invention relates to a crane traveling trolley with an ultrasonic anti-collision device, comprising a traveling trolley 1 and an ultrasonic distance measuring device 3 , the ultrasonic distance measuring device 3 is installed on the end of the traveling trolley 1 through a mounting bracket 2 .

[0018] Depend on figure 2 , image 3 It can be seen that due to the short wavelength of the ultrasonic wave, it is easy to obtain a directional and concentrated beam. The timing starts when the transmitter emits the ultrasonic wave and stops when the receiver receives the ultrasonic wave, so that the time t of the ultrasonic wave propagating in the air can be obtained directly. Calculate and solve the distance L between the measuring point and the measured obstacle.

[0019] Depend on Figure 4 It can be seen that the ultrasonic distance measuring device 3 includes a main control chip, an ultrasonic transmitting module, an ultrasonic receiving modu...

Abstract

The invention relates to a crane walking trolley with an ultrasonic wave anticollision device. The crane walking trolley with the ultrasonic wave anticollision device comprises a walking trolley (1). The crane walking trolley with the ultrasonic wave anticollision device is characterized by also comprising an ultrasonic wave ranging device (3) which is installed on the end part of the walking trolley (1) through an installation support (2), and comprises a main control chip, an ultrasonic wave emitting module, an ultrasonic wave receiving module, a data output module and a temperature compensation module. The crane walking trolley with the ultrasonic wave anticollision device can automatically monitor obstacles on a running track of a portal crane; when the distance between the crane and the obstacles is greater than the set safety distance, no action is generated; when the distance between the crane and the obstacles is less than the set safety distance, an alarming signal is sent out, and is transmitted to a driver cab and a PLC (programmable logic controller) through a data line, so that the crane reduces speed and is avoided timely, and the safety protection performance of the crane is increased.

Description

technical field [0001] The invention relates to a crane traveling trolley, in particular to a portal crane traveling trolley with an ultrasonic anti-collision device. It belongs to the technical field of hoisting machinery. Background technique [0002] The portal crane is a rail-operated crane, and the function of the operating mechanism is to change the working position of the portal crane. In order to meet the busy production needs, multiple portal cranes will be arranged on the same track to work together. In order to prevent the crane from derailing, a stop device will be set at the end of the track. [0003] Before the present invention, the conventional traveling trolley of the portal crane did not have the function of distance measurement and anti-collision. During the operation, two portal cranes on the same track would run opposite each other or collide with each other when the cranes were running near the car stop. danger.
