[0001] This utility model relates to the field of blowout preventer manufacturing technology, and in particular to a workbench for assembling a lower pressure cap. Background Technology

[0002] The blowout preventer housing assembly mainly consists of an upper housing assembly and a lower housing assembly. The upper housing assembly mainly includes the upper housing, outer cylinder, and lower pressure cap. The lower pressure cap is generally placed on the upper housing and outer cylinder. During assembly, the lower pressure cap is usually manually tapped to initially fit onto the upper housing and outer cylinder. Then, an auxiliary screw is connected to the top of the lower pressure cap, and finally, a tubular tool is used to press the lower pressure cap onto the upper housing and outer cylinder, thus completing the assembly. However, in actual operation, the lower pressure cap is usually tilted when first placed on the outer cylinder. Due to uneven tapping and pressing force, especially when the lower pressure cap is initially tapped to move it down, it may tilt, easily causing scratches on parts, leading to a decrease in product quality and even the risk of leakage. Utility Model Content

[0017] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0018] like Figures 1-3 As shown, this example provides a workbench for assembling a pressure cap, including: a base 100, a support component 200, and a pressure component 300.

[0019] A support ring 101 that moves vertically is provided above the base 100. The vertical movement of the support ring 101 can be connected to the moving end of a vertical lifting mechanism, which is installed on the base 100. The bearing assembly 200 includes a lifting ring 201 that is installed on the support ring 101 and moves vertically, and a plurality of side frames 202 that are located inside the support ring 101 and are equally spaced along its circumference. The side frames 202 move radially along the support ring 101. The lower pressure cover is supported by a support plate 203. Multiple equally spaced striking wheels 204 are arranged along the circumference of the inner side of the lifting ring 201 to strike the lower pressure cover, causing it to move downwards and initially engage with the upper shell and outer cylinder. The lower pressure assembly 300 includes a pressure ring 301 positioned above the support ring 101 and moving vertically. The pressure ring 301 rotates around its own axis and has multiple vertically arranged pressure tubes 302 on its inner side that move radially to abut against the lower... The auxiliary bolts on the top surface of the cover apply a downward force to the lower cover, ensuring it fully engages with the upper shell and outer cylinder. During assembly of the lower cover, the lifting ring 201 is first moved upwards to create sufficient space between the support ring 101 and the lifting ring 201 for the lower cover to pass through. The lower cover is then placed on the support plate 203. Next, the lifting ring 201 is moved downwards until the striking wheel 204 contacts the top surface of the lower cover. The lower cover is then continuously struck by the striking wheel, and the support plate 203... 3. Move downwards. The lower cover moves downwards continuously to achieve initial engagement between the lower cover and the upper shell and outer cylinder. At this time, move the bearing plate 203 away from the center of the support ring 101 until the bearing plate 203 is completely removed from under the lower cover. Then move the pressure tube 302 downwards. The lower end of the pressure tube 302 abuts against the auxiliary bolt on the surface of the lower cover and forces the lower cover to move downwards continuously, thereby fully engaging the lower cover with the upper shell and outer cylinder. Finally, move the support ring 101 upwards.

[0020] Specifically, the striking wheel 204 is connected to the vibrating end of the vibrating device, which is mounted on the cross frame 205. The vibrating device can be an electromagnetic vibrating striking device, a pneumatic vibrating striking device, or a mechanical vibrating striking device. The cross frame 205 is mounted on the lifting ring 201. After the lower cover is placed on the support plate 203, the lifting ring 201 can be moved downward until the striking wheel 204 abuts against the top surface of the lower cover. Then, the vibrating device forces the striking wheel 204 to start vibrating up and down. At the same time, the support plate 203 moves downward, thereby forcing the lower cover to move downward, achieving the initial engagement of the lower cover with the upper shell and the outer cylinder.

[0021] Specifically, the top surface of the support plate 203 is provided with a baffle 206. When the lower cover is placed on the support plate 203, the baffle 206 abuts against the side of the lower cover to limit the side of the lower cover for a period of time and prevent it from shifting.

[0022] Specifically, the support plate 203 is sleeved on the vertical rod 207, both ends of which are connected to the side frame 202. A spring 208 is sleeved on the vertical rod 207, with both ends of the spring 208 abutting against the lower end of the side frame 202 and the support plate 203 respectively, and always in a compressed state. Furthermore, a protruding plate 209 is provided on the inner side of the side frame 202 to abut against the bottom surface of the support plate 203. When the lower pressure cover is placed on the support plate 203, under the weight of the lower pressure cover, the support plate 203 will move downwards, further compressing the spring 208 until the support plate 203 abuts against... After the convex plate 209 is moved downwards, the support ring 101 is moved downwards until the lower cover abuts against the top of the upper shell and the outer cylinder. The support ring 101 continues to move downwards a certain distance. At this time, the spring 208 will reset a certain distance under its own elastic force. The bearing plate 203 always remains in contact with the bottom surface of the lower cover. Then, the lower cover can be knocked down by the knocking wheel 204 until the bearing plate 203 abuts against the convex plate 209 again. At this time, the knocking can be stopped, and the spring 208 will be compressed again. Then, the bearing plate 203 can be removed from under the lower cover to carry out subsequent operations.

[0023] Specifically, in order to facilitate the simultaneous movement of multiple side frames 202, a support plate 210 is provided on the outside of the side frame 202. The support plate 210 passes through the support ring 101. The outside of the side frame 202 is rotatably connected to one end of the connecting rod 211, and the other end of the connecting rod 211 is rotatably connected to the bottom ring 212. The bottom ring 212 is connected to the moving end of the first vertical lifting mechanism. The first vertical lifting mechanism is installed below the support ring 101. When it is necessary to move the side frame 202, the bottom ring 212 is driven to move in the vertical direction through the first vertical lifting mechanism. Under the drive of the connecting rod 211, the side frame 202 will be pulled to move radially along the support ring 101.

[0024] Specifically, the pressure tube 302 is installed on the top plate 303, which passes through the pressure ring 301. The pressure ring 301 is rotatably installed on the connecting ring 304, which is connected to the moving end of the second vertical lifting mechanism. The second vertical lifting mechanism is installed on the support ring 101. After the lower cover is finished being struck, the position of the pressure tube 302 is adjusted according to the position of the auxiliary bolt on the lower cover. That is, the pressure ring 301 is rotated around its own axis, and the top plate 303 is moved radially along the pressure ring 301 until the pressure tube 302 is directly above the auxiliary bolt. Then, the connecting ring 304 is driven downward by the second vertical lifting mechanism, and the pressure tube 302 applies force to the auxiliary bolt, thereby making the lower cover fully fit with the upper shell and the outer cylinder.

[0025] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
