Description

Technical Field

[0001] The utility model relates to the technical field of coupling protection, in particular to a coupling protection cover for a pump. Background Art

[0002] At present, according to the relevant protection standards for the use of electromechanical equipment GB8196 and other standards, during the operation of electromechanical equipment, the exposed parts of the rotating parts must be covered with protective covers to prevent people and other objects from touching them, endangering personal safety and property loss, and avoiding equipment jamming and failure. As a common rotating connection component, the coupling is widely used in the operation and transmission of electromechanical equipment. Its main function is to connect two transmission shafts and transmit torque.

[0003] In the prior art, for the protective cover designed on the coupling, the coupling protective cover and the machine pump are usually fixed to the base by bolts. Before inspecting and repairing the disc pump and the coupling, all the fixing bolts of the protective cover must be removed. The process is cumbersome and time-consuming. To solve the above problems, there is a patent application document in the prior art with application number CN202320298935.7: A coupling protective cover, which provides a stainless steel hinge and a buckle between the first cover body and the second cover body to achieve quick opening and closing of the protective cover.

[0004] However, this method still has certain problems: the staff can only open and close the protective cover on one side of the protective cover. When the staff is on the other side of the protective cover, they need to bypass or even step over the equipment to switch to the open side to open the protective cover. This process wastes time and there is even a safety hazard that the staff may directly step over the equipment to save time. Utility Model Content

[0005] The utility model aims at the problems in the prior art and provides a bidirectionally openable pump coupling protective cover, which solves the problem that the prior art can only be opened in one direction, which causes time-consuming or safety hazards when opening the cover.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A coupling protective cover for a pump includes a first cover body and two second cover bodies, the two ends of the first cover body are respectively connected to the two second cover bodies, the protective cover also includes two connecting mechanisms, the lower ends of the two connecting mechanisms are respectively connected to the upper ends of the two second cover bodies, the upper ends of the connecting mechanisms are connected to the lower end of the first cover body, and the connecting mechanisms can make the first cover body and the second cover body hingedly connected or separated. Through the two connecting mechanisms, the protective cover can be opened on both sides respectively, and the staff does not need to bypass or even cross the equipment to switch to the opening side to open the protective cover, which avoids wasting time in this process and even the safety hazard of the staff directly crossing the equipment to save time.

[0008] Preferably, the connection mechanism includes a connection pin hole fixedly arranged at the upper end of the second cover body, a pin shaft arranged on the first cover body and capable of reciprocating along the length direction of the first cover body, and the pin shaft can be inserted into the connection pin hole. Through the connection pin hole and the pin shaft, when opening, the staff only needs to pull out the pin shaft to complete the separation of the first cover body and the corresponding second cover body, and the pin shaft on the other side is always in an inserted state, at which time the protective cover can be opened, and the same applies if it is opened on the other side.

[0009] Preferably, a guide rail horizontally arranged along the length direction of the first cover body is fixed on the first cover body, a guide block is arranged on the guide rail, the guide block can reciprocate along the length direction of the guide block, and the pin is fixed on the guide block. The movement of the pin can be restricted by the guide rail and the guide block, so that the staff can better move the pin.

[0010] Preferably, each connection mechanism includes two connection pin holes, a guide block and a pin shaft, and the connection pin holes are symmetrically arranged on the second cover body. By setting the two connection pin holes, the guide block and the pin shaft, the two symmetrically arranged connection pin holes can be evenly stressed when opened, avoiding the deformation problem that a single connection pin hole is prone to when unevenly stressed.

[0011] Preferably, a stopper is provided on the guide rail, and the distance between the stopper and the two connecting pin holes is the same, and the stopper is used to limit the guide blocks on both sides. By providing the stopper, it is possible to ensure that when the pin is withdrawn, the moving distance is too large to be separated from the guide rail.

[0012] Preferably, a spring is provided between the stopper and the guide block, and the two ends of the spring are respectively in contact with the stopper and the guide block, and the spring is always in a compressed state. By providing a spring that is always in a compressed state, the pin shaft on the side that does not need to be opened can be always inserted into the connecting pin hole, thereby preventing the first cover body from being separated from the second cover body on the other side when opening.

[0013] Preferably, a chamfer is provided at one end of the pin shaft near the connecting pin hole. The chamfer can facilitate the insertion of the pin shaft.

[0014] Preferably, the first cover body has a semi-circular cross section, and an arrow mark is provided on the outer circumferential surface of the first cover body, and the arrow mark points around the axis of the circumferential surface of the first cover body. The provided arrow mark can facilitate the staff to know the rotation direction of the coupling in advance, and avoid incorrect rotation of the coupling during maintenance.

[0015] Preferably, the first cover body is also provided with two handles. Through the two provided handles, when the protective cover needs to be opened, the corresponding handles can be pulled, which is convenient for the staff to open.

[0016] Preferably, the handles are in different colors on the protective covers of the couplings for different purposes. When the handles are in different colors, it is convenient for the staff to distinguish between the running pump and the standby pump.

[0017] It can be seen from the above technical solutions that the advantages of the utility model are as follows: through the two connecting mechanisms, the protective cover can be opened on both sides respectively, and the staff does not need to bypass or even cross the equipment to switch to the opening side to open the protective cover, which avoids the waste of time in this process and even the safety hazards that the staff directly crosses the equipment to save time. Through the connection pin hole and pin shaft, the staff only needs to pull out the pin shaft to complete the separation of the first cover body and the corresponding second cover body when opening, and the pin shaft on the other side is always in an inserted state. At this time, the protective cover can be opened, and the same is true if it is opened on the other side. Through the guide rail and guide block, the movement of the pin shaft can be limited, which is convenient for the staff to move the pin shaft better. Through the two connection pin holes, guide blocks and pin shafts, the two connection pin holes symmetrically set when opening can be evenly stressed, avoiding the deformation problem that a single connection pin hole is unevenly stressed. Through the block, it can be ensured that when the pin shaft is pulled out, it is avoided that the moving distance is too large and it is separated from the guide rail. By providing a spring that is always in a compressed state, the pin shaft on the side that does not need to be opened can be always inserted into the connecting pin hole, thereby preventing the first cover body from being separated from the second cover body on the other side when opening.

[0018] The chamfers are designed to facilitate the insertion of the pin. The arrow marks are designed to help the staff know the direction of rotation of the coupling in advance, avoiding incorrect rotation of the coupling during maintenance. The two handles are designed so that the staff can pull the corresponding handle when the protective cover needs to be opened, which is convenient for the staff to open. When handles of different colors are designed, it is convenient for the staff to distinguish between the running pump and the standby pump. BRIEF DESCRIPTION OF THE DRAWINGS
