Description

Technical Field

[0001] The present application relates to the technical field of coupling shields, and in particular to a coupling shield and a coupling shield mounting structure. Background Art

[0002] Couplings are widely used in construction machinery, primarily connecting the output shaft and transmission shaft of power units (such as electric motors, engines, and hydraulic motors) to transmit power. Couplings are also known as "back wheels" in construction machinery. To prevent operators from accidentally hitting the coupling during rotation, potentially causing safety accidents, and to protect the coupling, a coupling guard is often used to cover the coupling.

[0003] The published patent document with the announcement number CN211288203U provides a coupling guard for a single-stage centrifugal compressor. This published patent document greatly improves the strength and rigidity of the coupling guard by providing a top guard reinforcement ring and a bottom guard reinforcement ring in the top guard and the bottom guard of the coupling guard respectively. During the production, transportation and use of the single-stage centrifugal compressor, the coupling guard is prevented from being easily deformed. In the above-mentioned device, the top guard and the bottom guard are fixed together by using several hexagonal head bolts and hexagonal nuts, which makes the installation and disassembly processes time-consuming and labor-intensive. Utility Model Content

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0006] The coupling guard includes a coupling bottom cover, which is hinged to the coupling top cover by a hinge, and a positioning cylinder is fixedly installed on the side of the lower surface of the coupling bottom cover away from the hinge, and an adjusting rod is slidably inserted into the interior of the positioning cylinder, and the lower end of the adjusting rod is fixedly connected to an adjusting block, and the upper surface of the adjusting block is fixedly connected to a spring, and the upper end of the spring is fixedly connected to the lower surface of the coupling bottom cover. Under the action of the spring, the upper end of the adjusting rod slides through the coupling bottom cover and the coupling top cover to the outside, and a placement groove is provided at the upper end of the adjusting rod, and a clamping block is rotatably connected to the inside of the placement groove, and the lower surface of the clamping block abuts against the upper surface of the coupling top cover.

[0007] By adopting the above technical solution, the coupling bottom cover and the coupling top cover are movably hinged together by setting a hinge, and the cooperation between the spring and the adjusting block is utilized to facilitate the adjustment of the position of the adjusting rod. When the coupling bottom cover and the coupling top cover need to be fixedly connected together, the adjusting rod and the clamping block are driven to move upward by pressing the adjusting block. When the clamping block completely penetrates the coupling top cover, the clamping block is rotated so that it is vertical to the adjusting rod. At this time, the adjusting block is released, and the clamping block will move downward under the action of the spring and abut against the coupling top cover, that is, the coupling top cover can be fixed to the coupling bottom cover. Through this device, the installation and disassembly process of the coupling cover is very convenient and labor-saving.

[0008] As a preferred technical solution of the present application, a plug-in hole is formed through the upper surfaces of the coupling bottom cover and the coupling top cover, and the outer diameter of the adjustment rod is adapted to the inner diameter of the plug-in hole.

[0009] By adopting the above technical solution, it is ensured that the adjusting rod can slide and plug back and forth inside the coupling bottom cover and the coupling top cover.

[0010] As a preferred technical solution of the present application, a top cover reinforcement ring is fixedly welded inside the top cover of the coupling, and a bottom cover reinforcement ring is fixedly welded inside the bottom cover of the coupling.

[0011] By adopting the above technical solution, by providing a top cover reinforcement ring and a bottom cover reinforcement ring inside the coupling top cover and the coupling bottom cover respectively, the overall strength and rigidity of the coupling cover can be improved, avoiding the situation where the coupling cover is easily deformed.

[0012] As a preferred technical solution of the present application, the coupling top cover is a semicircular arc structure, and the coupling bottom cover is a semi-hexagonal structure.

[0013] By adopting the above technical solution, the coupling top cover adopts a semicircular arc structure, and the coupling bottom cover adopts a semi-hexagonal structure, making it more compact in structure, reducing the overall dimensions of the coupling shield, and making it more beautiful in appearance.

[0014] As a preferred technical solution of the present application, the positioning cylinder, the adjusting rod, the adjusting block, the spring and the clamping block are all made of stainless steel.

[0015] By adopting the above technical solution, the positioning cylinder, the adjusting rod, the adjusting block, the spring and the clamping block made of stainless steel have strong corrosion resistance, are not easy to be damaged and have a long service life.

[0016] The coupling guard mounting structure works in conjunction with the coupling guard. The main body of the coupling guard mounting structure is a mounting unit. The mounting unit includes a base, and columns are symmetrically installed on the top of the base. Telescopic rods are slidably inserted into the interior of the two columns, and the top of the telescopic rods is fixedly connected to the bottom of the coupling bottom cover.

[0017] By adopting the above technical solution, the coupling shield is supported by the cooperation between the base, the column and the telescopic rod, so that the coupling shield can be installed on the coupling.

[0018] As a preferred technical solution of the present application, a threaded connection hole is opened on the outer wall of the column near the upper end, and the internal thread of the threaded connection hole is connected to a fixing bolt, and the column is fixedly connected to the telescopic rod through the fixing bolt.

[0019] By adopting the above technical solution, the overall height of the installation unit can be adjusted within a certain range according to the positions of couplings at different heights, thereby improving the applicability of the device.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In the utility model, the coupling bottom cover and the coupling top cover are movably hinged together by setting a hinge, and the cooperation between the spring and the adjusting block is utilized to facilitate the adjustment of the position of the adjusting rod. When the coupling bottom cover and the coupling top cover need to be fixedly connected together, the adjusting block is pressed to drive the adjusting rod and the clamping block to move upward. When the clamping block completely penetrates the coupling top cover, the clamping block is rotated to make it perpendicular to the adjusting rod. At this time, the adjusting block is released, and the clamping block will move downward under the action of the spring and abut against the coupling top cover, that is, the coupling top cover can be fixed to the coupling bottom cover. Through this device, the installation and removal process of the coupling cover is very convenient and labor-saving.

[0022] 2. In the utility model, the coupling guard is supported by the mounting unit so that the coupling guard can be installed on the coupling.
