Description

Technical Field

[0001] This utility model relates to the field of installation device technology, and in particular to a boiler installation device with a double drum. Background Technology

[0002] During the installation of a double-drum boiler, it is crucial to ensure the positioning accuracy and stability of the upper and lower drums to guarantee precise welding of the evenly distributed connecting pipes. Existing installation methods have certain shortcomings. For example, the support structure cannot be adapted to different drum sizes, or the support structure is directly welded to the drum to provide support, but this method is difficult to adjust during subsequent installations, lacking flexibility and practicality. Furthermore, some installation processes involve working at heights, requiring workers to frequently move up and down using ladders and other tools, posing safety hazards and resulting in low installation efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a boiler installation device with a double drum, which has the advantages of being safer, more efficient, and more versatile, and solves some of the problems mentioned in the background technology.

[0004] This utility model provides the following technical solution: a boiler installation device for a double-drum boiler, including a vertical frame, a lower water drum, and an upper steam drum. The vertical frame is provided in four sets, which are symmetrical to each other in both longitudinal and transverse directions. A swing arm is rotatably installed on the vertical frame near the middle of the upper side. A fixed rod is fixedly installed on the swing arm near the middle of the lower side at the end away from the vertical frame. A movable sleeve is rotatably sleeved on the outer side of the fixed rod. A sliding groove is provided in the middle of the inner side of the vertical frame. A screw rod passes through the inner side of the sliding groove in the longitudinal direction. Anti-detachment sleeves are threaded on both the front and rear ends of the screw rod. Sliding sleeves are slidably sleeved on the outer side of the screw rod near the anti-detachment sleeves at both the front and rear ends. A rotating connecting seat is fixedly connected to the lower end of each sliding sleeve. An adjusting screw rod is rotatably connected to the lower end of each rotating connecting seat.

[0005] Furthermore, a rolling bearing is fixedly sleeved between the swing arm and the upright at the joint, and the outer ring of the rolling bearing is fixedly connected to the upright, which improves the flexibility of the swing arm, reduces structural wear, and improves accuracy.

[0006] Furthermore, a stop block is fixedly connected to one end of the swing arm near the upright. The stop block fits against the upright and supports the swing arm to prevent bending due to excessive load.

[0007] Furthermore, a threaded cylinder is fixedly installed at the middle of one outer end of the base of the support frame. The lower end of the adjusting screw is threadedly connected to the threaded cylinder. With the help of the rotating connecting seat, the lifting and lowering can be achieved by directly rotating the adjusting screw.

[0008] Furthermore, each of the bases of the support frame has a threaded seat fixedly installed at the middle of one inner end. Horizontally, each of the threaded seats is connected to a screw rod. The threaded seats provide support and fixation for the screw rod and allow for adjustment of the spacing.

[0009] Furthermore, the fixed rod and movable sleeve on the left longitudinal direction respectively abut against the upper end of the inner wall of the opening at both ends of the lower water cylinder, and the fixed rod and movable sleeve on the right longitudinal direction respectively abut against the upper end of the inner wall of the opening at both ends of the upper steam drum. It is worth mentioning that when installing the connecting pipe, it is necessary to adopt the installation method of spreading from the middle to the front and back and up and down. At the same time, installing the straight pipe from the middle also facilitates the positioning and correction of the boiler drum.

[0010] The advantages of this utility model are as follows:

[0011] 1. This installation device adopts a horizontal installation method, which eliminates the need for installers to work at heights using ladders, effectively reducing the risk of operation. Through the structure of uprights, fixing rods, screws and other components, the upper and lower drums are fixed in multiple dimensions to prevent the drums from swaying back and forth or shifting left and right during welding, thus ensuring the welding accuracy of the connecting pipes and improving installation efficiency.

[0012] 2. The device connects and fixes the frame and the boiler drum through detachable components such as screw one, screw two, and anti-detachment sleeve, making disassembly and assembly convenient. At the same time, the adjusting screw can be raised and lowered, and with the rotation design of the movable sleeve, it can adapt to the installation requirements of double-drum boilers of different sizes, greatly improving the versatility and flexibility of the device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4A boiler installation device for a double-drum boiler includes a support frame 1, a lower water drum 16, and an upper steam drum 17. The support frame 1 has four sets of components symmetrically arranged in both longitudinal and transverse directions. A swing arm 2 is rotatably mounted on the support frame 1 near the upper center. A fixed rod 4 is fixedly mounted on the swing arm 2 near the lower center at the end furthest from the support frame 1. A movable sleeve 5 is rotatably sleeved on the outer side of the fixed rod 4. A sliding groove 7 is provided in the inner center of the support frame 1. A screw rod 8 passes through the interior of the sliding groove 7 longitudinally. Anti-detachment sleeves 9 are threaded onto both ends of the screw rod 8. Sliding sleeves 12 are slidably sleeved on the outer side of the screw rod 8 near the anti-detachment sleeves 9 at both ends. A rotating connecting seat 13 is fixedly connected to the lower end of each sliding sleeve 12. An adjusting... A threaded cylinder 10 is fixedly installed at the middle of the outer end of the base of the support frame 1 on the adjusting screw 11. The lower end of the adjusting screw 11 is threadedly connected to the threaded cylinder 10. A threaded seat 14 is fixedly installed at the middle of the inner end of the base of the support frame 1. A screw 15 is threaded through and threaded between the threaded seats 14 in the transverse direction. The fixed rod 4 and the movable sleeve 5 on the left longitudinal direction respectively abut against the upper end of the inner wall of the opening at the front and rear ends of the lower water cylinder 16. The fixed rod 4 and the movable sleeve 5 on the right longitudinal direction respectively abut against the upper end of the inner wall of the opening at the front and rear ends of the upper steam drum 17. The fixed rods 4 on the two sets of support frames 1 in the longitudinal direction provide support for the front and rear ends of the lower water cylinder 16 and the upper steam drum 17, and at the same time make the swing arm 2 connected to the lower water cylinder 16 or the upper steam drum 17. To prevent slippage, the swing arm 2 will move vertically downwards under the gravity of the lower water cylinder 16 or the upper steam drum 17. Simultaneously, the fixing rod 4 will abut against the upper middle of the openings at both ends of the lower water cylinder 16 or the upper steam drum 17. Then, the screw 8 is inserted into the corresponding two sets of sliding grooves 7 and sliding sleeves 12, allowing the screw 8 to penetrate the interior of the lower water cylinder 16 or the upper steam drum 17. The anti-detachment sleeve 9 is screwed onto the front and rear ends of the screw 8 and abuts against the corresponding uprights 1, thus completing the longitudinal fixation between the two sets of uprights 1. This prevents back-and-forth swaying when welding pipes between the lower water cylinder 16 and the upper steam drum 17. The adjusting screw 11 can be adjusted for height, allowing the screw 8 to abut against the lower water cylinder 16 or the upper steam drum 17. The lower end of the inner wall of 7, together with the fixing rod 4, limits and fixes the lower water cylinder 16 or the upper steam drum 17, preventing them from swaying left and right during welding and installation. Furthermore, the design of the movable sleeve 5 allows workers to easily rotate the lower water cylinder 16 or the upper steam drum 17, effectively reducing wear between structures, thus ensuring that the reserved pipe holes correspond. By using the screw 15 to pass through and threadedly connect the threaded seats 14 on the two sets of horizontal uprights 1, the stability of this device during installation and use can be improved, while maintaining the horizontality between the lower water cylinder 16 and the upper steam drum 17. Moreover, the lower water cylinder 16 and the upper steam drum 17 will be at the same height under the action of gravity, thereby preventing the welded steam pipes from becoming skewed. Compared with the current installation method for double-drum boilers,This horizontal installation method is not only safer but also eliminates the need for installers to use ladders to move up and down, greatly improving installation efficiency. It also facilitates the removal of screws 1-8 and 2-15, as well as the separation of the support frame 1 and fixing rod 4 from the lower water drum 16 and upper steam drum 17. The installation is convenient and suitable for installing double-drum boilers of different sizes, offering greater flexibility.

[0020] Please see Figure 3 A rolling bearing 3 is fixedly sleeved between the swing arm 2 and the upright frame 1 at the junction. The outer ring of the rolling bearing 3 is fixedly connected to the upright frame 1. A stop block 6 is fixedly connected to the swing arm 2 at one end near the upright frame 1. The stop block 6 fits against the upright frame 1, ensuring the rationality of the structural design of this device.

[0021] Working principle: During use, the fixing rods 4 on the two sets of vertical supports 1 provide support for the front and rear ends of the lower water cylinder 16 and the upper steam drum 17. Simultaneously, the swing arm 2 is engaged with the lower water cylinder 16 or the upper steam drum 17 to prevent slippage. Under the weight of the lower water cylinder 16 or the upper steam drum 17, the swing arm 2 will move vertically downwards. At the same time, the fixing rods 4 will abut against the upper middle of the openings at the front and rear ends of the lower water cylinder 16 or the upper steam drum 17. Then, the screw 8 is inserted into the interior of the corresponding two sets of sliding grooves 7 and sliding sleeves 12, allowing the screw 8 to penetrate the interior of the lower water cylinder 16 or the upper steam drum 17. The anti-detachment sleeve 9 is screwed onto the front and rear ends of the screw 8 and abuts against the corresponding vertical supports 1, thus completing the fixation between the two sets of vertical supports 1 in the longitudinal direction and preventing slippage between the lower water cylinder 16 and the upper steam drum 17. When welding pipes, the pipes can sway back and forth. Adjusting the screw 11 allows for height adjustment, enabling the screw 18 to press against the lower end of the inner wall of the lower water cylinder 16 or the upper steam drum 17. This, combined with the fixing rod 4, limits and fixes the lower water cylinder 16 or the upper steam drum 17, preventing swaying during welding and installation. Furthermore, the movable sleeve 5 design allows workers to easily rotate the lower water cylinder 16 or the upper steam drum 17. By using the screw 2 15 to pass through and threadedly connect to the threaded seats 14 on the two horizontally mounted supports 1, the stability of the device during installation and use is improved. This maintains the horizontality between the lower water cylinder 16 and the upper steam drum 17, ensuring they are at the same height under gravity, thus preventing the welded steam pipes from becoming skewed.
