Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to a connecting device. Background Art

[0002] The CPS-NG system is a new type of coke oven carbonization chamber stabilization system in China. It can effectively reduce pollutant emissions during the coking process, improve the environmental protection level of coke ovens, improve the operating environment of coke ovens, improve the automation level of coke oven production, and extend the service life of coke ovens. The CPS-NG system includes an automatic adjustment function for the water seal valve disc in the carbonization chamber, which is mainly driven by the cylinder to transport the water seal valve disc. However, the space available for installation on site is small. For example, 70 pipes need to be laid in parallel in a coke oven carbonization chamber, and the space available for installation between pipes is very limited. Therefore, it is necessary to design a connection device between the cylinder and the water seal valve, which should be small and stable and firmly connected to the cylinder and the water seal valve to meet the requirements. Utility Model Content

[0003] In order to solve the technical problem of lack of a connecting device between the cylinder and the water seal valve in the prior art, the present application proposes a connecting device to solve the above technical problem.

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

[0005] The utility model provides a connecting device for connecting a cylinder body to a valve installed in a pipeline, comprising: a supporting member, the supporting member is sleeved on a shell protrusion on the periphery of a valve plate rotating shaft of the valve, and is fixedly connected to the shell protrusion; a connecting body, the connecting body comprising a fixing plate and a connecting plate arranged at both ends of the main body, the fixing plate is fixedly connected to the supporting member, and is penetrated by the valve plate rotating shaft, and at the same time, a pressure cover provided by the valve and cooperating with the shell protrusion is also fixed on the fixing plate, and a fixing point between the pressure cover and the fixing plate and a fixing point between the shell protrusion and the fixing plate are at different positions, and the connecting plate is connected to the outer shell of the cylinder body.

[0006] Furthermore, a socket is formed on the support member, and the shape of the socket matches the shape of the protrusion of the shell.

[0007] Furthermore, the fixing plate and the supporting member are provided with tightening bolts, and the screwed-in end of the rod body of the tightening bolt passes through the fixing plate and the supporting member and is tightened against the outer wall of the valve housing.

[0008] Furthermore, the connector also includes a connecting wall, which is formed between the fixing plate and the connecting plate, and a avoidance opening is formed on the connecting wall.

[0009] Furthermore, it also includes a power transmission sleeve, one end of which is inserted into the rotating gear in the cylinder body and connected to the rotating gear, and the other end of which is inserted into the valve plate rotating shaft and fixedly connected to the valve plate rotating shaft.

[0010] Furthermore, a group of connecting holes are opened on the end surface of one end of the power transmission sleeve inserted into the cylinder body, and a first screw is arranged in the connecting hole. The first screw is screwed into the end of the valve plate shaft to fix the power transmission sleeve on the valve plate shaft; at the same time, a connecting protrusion connected to the rotating gear is formed in the center of the end surface of one end of the power transmission sleeve inserted into the cylinder body, and the connecting protrusion is inserted into the tooth hole in the center of the rotating gear and is driven by the rotating gear.

[0011] Furthermore, at least two groups of adjustment and fixing holes are opened on the side wall of the power transmission sleeve, and a second screw is arranged in the adjustment and fixing hole. The second screw is screwed into the side wall of the valve plate shaft. The coaxiality of the valve plate shaft and the rotating gear is adjusted and maintained by adjusting the screwing depth of the second screw.

[0012] Furthermore, a gravity rod with a counterweight is connected to the power transmission sleeve. When the cylinder body is not working, the gravity rod drives the power transmission sleeve and the valve plate shaft to rotate under the action of gravity to close the valve.

[0013] Furthermore, a thin rod for being sleeved by an external extension tube is formed on the gravity rod.

[0014] Based on the above technical solution, the technical effects that can be achieved by the utility model are:

[0015] The connecting device of the utility model first sets a support member on the shell protrusion outside the valve plate shaft, and then fixes the pressure cover of the valve on the fixing plate, the connecting plate is fixedly connected to the cylinder body, and the valve plate shaft passes through the support member and the fixing plate to be connected to the cylinder body. The connecting device of the utility model forms a connecting bridge between the valve body and the cylinder body. The role of designing the support member is that if there is only a connecting body, then the fixed connection point between the cylinder body and the valve body will bear the supporting role alone. Due to the heavy weight of the cylinder body itself, during operation, the fixed connection point between the cylinder body and the valve body is prone to damage and deformation, and the valve body shaft will move circumferentially, affecting the coaxiality, causing damage to the valve and the cylinder body, and the stability is extremely poor. After the support member is designed, the force surface of the cylinder acting on the valve body becomes larger, and the force applied by the cylinder body is shared by the support member between the support member and the shell protrusion. The sleeve is set; further, the fixing points between the pressure cover and the fixed plate and the fixing points between the shell protrusion and the fixed plate are at different positions, and the force applied by the cylinder body is further disassembled and acts on multiple fixing points to further share the force applied by the cylinder body. At the same time, the fixing points between the pressure cover and the fixed plate and the fixing points between the shell protrusion and the fixed plate are designed at different positions, which makes installation more convenient. Specifically, if the fixing points between the pressure cover and the fixed plate and the fixing points between the shell protrusion and the fixed plate are designed at the same position, then multiple debugging is required during installation, and in the later operation, the valve body shaft is still prone to circumferential movement. In summary, the present application provides a connecting device between the valve and the cylinder body, which is small and enables the cylinder and the valve to be stably and firmly connected, thereby meeting the operation requirements.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] The valve a involved in the utility model is mainly a water seal valve a, and the cylinder body b is mainly an angular stroke cylinder.

[0032] like Figure 1-10As shown, the utility model provides a connection device for connecting a cylinder body b to a valve a installed in a pipeline, comprising a support member 1 and a connection body 2, wherein the support member 1 is sleeved on a housing protrusion a2 outside a valve plate rotating shaft a1 of the valve a and is fixedly connected to the housing protrusion a2, and the connection body 2 comprises a fixing plate 21 and a connecting plate 22 arranged at both ends of the body, the fixing plate 21 is fixedly connected to the support member 1 and is penetrated by the valve plate rotating shaft a1, and at the same time, a pressure cover a3 of the valve a that matches the housing protrusion a2 is also fixed on the fixing plate 21, and the pressure cover a3 is fixed to the fixing plate 22. 1 and the fixing point between the shell protrusion a2 and the fixing plate 21 are at different positions. Specifically, the position of the pressure cover a3 of the valve a corresponds to the position of the shell protrusion a2. In the present application, the pressure cover a3 is rotated ninety degrees along the axis, and the fixing point between the pressure cover a3 and the fixing plate 21 is connected by two bolts, and the shell protrusion a2 and the fixing plate 21 are connected by another two bolts. The connecting plate 22 is connected to the outer shell of the cylinder body b. Specifically, a threaded hole b2 is provided on the bottom plate of the outer shell of the cylinder body b, and a hole is opened on the connecting plate 22 at a position opposite to the threaded hole b2 to facilitate the implementation of screw connection.

[0033] In a specific embodiment of the present invention, a socket 11 is formed on the support member 1, and the shape of the socket 11 matches the shape of the housing protrusion a2, such as a rhombus in this embodiment.

[0034] In a specific embodiment of the present invention, a tightening bolt 25 is arranged on the fixing plate 21 and the support member 1. The screwed-in end of the rod of the tightening bolt 25 passes through the fixing plate 21 and the support member 1 and is tightened on the outer wall of the shell of the valve a to further improve the connection tightness between the valve a, the support member 1 and the fixing plate 21, thereby improving the stability of the later operation of the equipment.

[0035] In a specific embodiment of the present invention, the connector 2 further includes a connecting wall 23 formed between the fixing plate 21 and the connecting plate 22 , and a clearance opening 24 is formed on the connecting wall 23 to provide operating space during assembly.

[0036] In a specific embodiment of the present utility model, a power transmission sleeve 3 is also configured at the cylinder body b, one end of the power transmission sleeve 3 is inserted into the rotating gear b1 in the cylinder body b and connected to the rotating gear b1, and the other end of the power transmission sleeve 3 is inserted into the valve plate rotating shaft a1 and fixedly connected to the valve plate rotating shaft a1.

[0037] Furthermore, a group of connecting holes 31 are opened on the end surface of one end of the power transmission sleeve 3 inserted into the cylinder body b, and a first screw is arranged in the connecting hole 31. The first screw is screwed into the end of the valve plate shaft a1 to fix the power transmission sleeve 3 on the valve plate shaft a1; at the same time, a connecting protrusion 32 connected to the rotating gear b1 is formed in the center of the end surface of one end of the power transmission sleeve 3 inserted into the cylinder body b, and the connecting protrusion 32 is inserted into the tooth hole in the center of the rotating gear b1 and is driven by the rotating gear b1.

[0038] Furthermore, at least two groups of adjustment and fixing holes 33 are provided on the side wall of the power transmission sleeve 3, and second screws are arranged in the adjustment and fixing holes 33. The second screws are screwed into the side wall of the valve plate shaft a1, and the coaxiality between the valve plate shaft a1 and the rotating gear b1 is adjusted and maintained by adjusting the screwing depth of the second screws. The two groups of second screws can make the connection between the valve plate shaft a1 and the power transmission sleeve 3 more secure, so as to prevent the valve body shaft from circumferential movement.

[0039] In a specific embodiment of the utility model, a gravity rod 4 with a counterweight 41 is also connected to the power transmission sleeve 3. When the cylinder body b is not working, the gravity rod 4 drives the power transmission sleeve 3 and the valve plate shaft a1 to rotate under the action of gravity to close the valve a. The gravity rod 4 plays a safety role. When the workshop has a power outage, the cylinder body b cannot work. To ensure safety, the gravity rod 4 drives the power transmission sleeve 3 to rotate under the action of gravity, thereby driving the valve plate shaft a1 to rotate and close the valve a.

[0040] In a specific embodiment of the utility model, a thin rod 42 for being sleeved by an external extension tube is formed on the gravity rod 4. The thin rod 42 is convenient for the on-site staff to manually control the opening and closing of the valve a when the cylinder body b is not working. The thin rod 42 is used to sleeve the extension tube to form a force arm, so that the on-site staff can open or close the valve a more labor-saving. At the same time, the pipeline valve a of the coke oven carbonization chamber is arranged at a high place. If there is no thin rod 42 to sleeve the extension tube, the on-site staff needs to stand at a high place with the help of facilities to control the valve a. The pipeline valve a of the coke oven carbonization chamber is usually accompanied by high temperature. If the on-site staff is too close, it will also affect safety. The setting of the thin rod 42 not only facilitates on-site operation, but also improves safety.

[0041] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
