Detailed Description
The following disclosure provides many different embodiments or examples for implementing different features of the invention. In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or reference letters in the various examples, which have been repeated for purposes of simplicity and clarity and do not in themselves dictate a relationship between the various embodiments and/or arrangements discussed. In addition, the present disclosure provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.
The action flow of the wire rope puller on the current market sends out the allotment instruction through the general monitoring of tower bridge, the action of the ware is pulled in the communication control of below operating personnel through the intercom, and the many places action flows of tower bridge general monitoring, in case control error or intercom are malfunctioning, then can lead to pulling the arm-drag of ware and hit the return pulley, all can cause the arm-drag to damage under the general condition, thereby need consume manpower and materials and time and change the arm-drag, more lead to the condition that the wire rope bursts apart, thereby cause serious engineering accident, cause very big influence to site personnel's safety.
In order to avoid the collision of dragging ware and return pulley, the technical scheme of the utility model provides a drag ware restricted movement protection device. The technical scheme is as follows:
the invention is explained in further detail below with reference to fig. 1.
As shown in fig. 1, the utility model provides a drag ware restricted driving protection device, including first connecting rod 1, second connecting rod 2, third connecting rod 3 and return pulley 4, first connecting rod 1 is articulated with third connecting rod 3, third connecting rod 3 is articulated with second connecting rod 2, but second connecting rod 2 and first connecting rod 1 sliding connection, first connecting rod 1 is equipped with the junction of second connecting rod 2 and drags the pull head, second connecting rod 2 is equipped with power device 5 with the handing-over department of third connecting rod 3, first connecting rod 1 is equipped with signal receiver 6 with the articulated department that shown third is connected, it is equipped with eight at least signal emitter 7 to surround the 4 centre of a circle of return pulley on the return pulley 4.
Through the setting of signal emission device 7 and signal receiving device 6, when the ware is drawn near return pulley 4 to the dragging, the signal that the signal transmitter on the ware was drawn to the signal receiving device 6 on the ware just can receive return pulley 4 launches, thereby give the control cabinet and force the instruction that stops to draw the action, and then make and draw the ware stop work, finally avoided dragging the ware and return pulley 4's collision, thereby guaranteed the stability and the security of dragging the ware, and then guaranteed the security of engineering.
Specifically, the signal transmission radius of the signal transmission device 7 is 15cm, and the signal reception radius of the signal reception device 6 is 20 cm.
In practical use, the signal emitting device 7 and the signal receiving device 6 may be a photoelectric sensing switch or a sound wave emitting and sensing switch, or may also be an infrared distance sensor, which is not limited herein.
Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the invention following, in general, the principles of the invention and including such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains.
