Description

Technical Field

[0001] The utility model belongs to the technical field of coupling shields, in particular to a coupling shield that can be quickly installed. Background Art

[0002] Couplings in mechanical equipment, such as pumps and fans, connect the drive and working ends. They are typically protected by a shield to prevent foreign objects from falling onto the coupling and potentially damaging the equipment. This also prevents personnel from accidentally touching the high-speed rotating coupling, potentially causing injury. Currently, couplings are often shielded by an arched plate bolted to the equipment. However, this method requires a wrench to disassemble, requiring a wrench for every inspection. Summary of the Invention

[0003] The purpose of the utility model is to provide a coupling shield that can be quickly installed to solve the problems existing in the prior art.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A coupling shield which can be quickly installed comprises a shield body. A plurality of legs are welded on the bottom of the shield body. The legs are all plugged with guide tubes, and the guide tubes are plugged with bottom tubes.

[0006] Furthermore, the shield body is an arched structure, and a plurality of legs are symmetrically distributed on two lower edges of the arched structure of the shield body.

[0007] Furthermore, the bottom tube is a hollow tubular structure, and the inner diameter of the bottom tube is larger than the diameter of the supporting legs.

[0008] Furthermore, the guide tube is a tapered tube, and four guide pieces are inclinedly provided at the top end of the guide tube.

[0009] Furthermore, the outer diameter of the top end of the guide tube is larger than the inner diameter of the bottom tube, the outer diameter of the bottom end of the guide tube is smaller than the inner diameter of the bottom tube, and the inner diameter of the bottom end of the guide tube is larger than the diameter of the support leg.

[0010] Furthermore, the guide piece is arc-shaped, and the inclination angle of the guide piece is 30 degrees. The four guide pieces are distributed on the top end of the guide tube in an array with the central axis of the guide tube as the axis.

[0011] The utility model has the following beneficial effects:

[0012] 1. The utility model can quickly complete the installation of the shield without using a wrench, thereby improving the installation efficiency of the coupling shield and saving inspection and maintenance time.

[0013] 2. Push the guide tube downward, and the legs slide downward along the guide piece, so that the legs can be accurately inserted into the guide tube. In this way, when the shield body is deformed, the legs are not vertical, the bottom tube welding has deviations, and the legs are difficult to insert into the bottom tube, the guide tube can still be used to guide the legs and complete the installation quickly.

[0014] 3. The guide piece is bent outward 30 degrees to form a flared structure, which plays a guiding role.

[0015] 4. The guide tube and guide plate are easy to manufacture and have low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] like Figure 1-3 As shown, a coupling shield that can be quickly installed includes a shield body 1. A plurality of legs 2 are welded to the bottom of the shield body 1. Guide tubes 3 are inserted into the legs 2, and bottom tubes 4 are inserted into the guide tubes 3.

[0022] The shield body 1 is an arched structure, and a plurality of legs 2 are symmetrically distributed on the two lower edges of the arched structure of the shield body 1.

[0023] The bottom tube 4 is a hollow tubular structure, and the inner diameter of the bottom tube 4 is larger than the diameter of the supporting leg 2 .

[0024] The guide tube 3 is a tapered tube, and four guide pieces 5 are inclinedly provided at the top end of the guide tube 3 .

[0025] The outer diameter of the top end of the guide tube 3 is larger than the inner diameter of the bottom tube 4 , the outer diameter of the bottom end of the guide tube 3 is smaller than the inner diameter of the bottom tube 4 , and the inner diameter of the bottom end of the guide tube 3 is larger than the diameter of the support leg 2 .

[0026] The guide piece 5 is arc-shaped, and the inclination angle of the guide piece 5 is 30 degrees. The four guide pieces 5 are distributed in an array at the top end of the guide tube 3 with the central axis of the guide tube 3 as the axis.

[0027] The working principle of this utility model is:

[0028] During use, weld the bottom tube 4 to the equipment on both sides of the coupling, insert the guide tube 3 into the bottom tube 4, and then insert the legs 2 into the guide tube 3. If the shield body 1 is deformed, or the legs 2 deviate during welding, causing them to be non-vertical, or if the position of the bottom tube 4 deviates during welding, push the guide tube 3 downward, and the legs 2 will slide downward along the guide piece 5, so that the legs 2 can be accurately inserted into the guide tube 3.

[0029] When making the guide tube 3, the top of a tapered tube can be cut into four parts, and then the top of the cut tapered tube can be bent outward 30 degrees to form the guide piece 5. In order to ensure strength, the outer side of the guide piece 5 can be repaired by welding to strengthen the connection between the guide piece 5 and the guide tube 3.

[0030] The above-described embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention.

[0031] The technology, shape and structure that are not described in detail in this utility model are all well-known technologies.
