Detailed Description
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the invention have been omitted.
As shown in fig. 1 to 3, the embodiment of the present invention discloses a guard device 10, which is used for preventing a pipe body on a frame 100 of a transportation vehicle from flying out of the frame 100 due to the unstable running of the vehicle.
Each transport vehicle is provided with two guards 10 for protecting the two ends of the restraining tube respectively. Each guard 10 comprises: a protection net 11, ropes 12, a drum 13, a ratchet 14, a pawl 15, and a biasing means.
The protective net 11 can be a metal protective net 11, and the protective net 11 is covered on the end of the pipe body; the rope 12 may be a wire rope, and one end of the rope 12 is connected to the protection net 11 by a pull ring for pulling the protection net 11.
The winding drum 13 and the ratchet 14 are coaxially arranged, the winding drum 13 is rotatably arranged in the middle of the frame 100, the other end of the rope 12 is wound on the winding drum 13, and the ratchet 14 rotates to drive the winding drum 13 to rotate.
The middle part of the ratchet 14 is provided with a force application hole, the force application tool can be a crank, and the head part of the crank extends into the force application hole, so that the ratchet 14 is driven to rotate by rotating the crank.
The pawl 15 is rotatably mounted on the frame 100 on one side of the ratchet 14, the head of the pawl 15 extends into the tooth groove of the ratchet 14 to restrict the rotation of the ratchet 14, and the rotation of the ratchet 14 is released by separating the pawl 15 from the ratchet 14.
The working process of the protection device 10 provided by the invention is as follows:
the pawl 15 is separated from the ratchet 14 by rotating the pawl 15, then the ratchet 14 is rotated by the crank to rotate the drum 13 by the ratchet 14, and the rope 12 is tightened against the protection net 11, and finally, the drum 13 is restricted from rotating by the head of the pawl 15 protruding into the tooth groove of the ratchet 14, and the rope 12 is prevented from slackening.
The advantages of the guard 10 provided by the present invention are:
the rope 12 can be conveniently and rapidly tensioned through the matching of the ratchet wheel 14, the pawl 15, the winding drum 13 and the rope 12, so that the protective net 11 is tightly coated on the end part of the pipe body, and the rope 12 can be effectively prevented from being loosened.
Moreover, although exemplary embodiments have been described herein, the scope of the present invention includes any and all embodiments based on the present invention with equivalent elements, modifications, omissions, combinations (e.g., of various embodiments across), adaptations or alterations. The elements of the claims are to be interpreted broadly based on the language employed in the claims and not limited to examples described in the present specification or during the prosecution of the application, which examples are to be construed as non-exclusive.
