Description

Technical Field

[0001] The utility model belongs to the technical field of pressure vessels, and in particular relates to a supporting device for an outlet nozzle of a pressure vessel. Background Art

[0002] A pressure vessel is a closed container specially designed to withstand internal pressure or both internal and external pressure. Such containers usually operate under high temperature and high pressure or store and transport special media. At present, in order to increase the safety and stability of the pressure vessel outlet nozzle, a special support device for the pressure vessel outlet nozzle is usually used.

[0003] The authorization announcement number is CN 220118957 U. A support device for a pressure vessel outlet nozzle includes a support plate, a first support plate, a first support vertical plate, a second support plate, and a second support vertical plate. The first support vertical plate is provided with a first support plate on the top, and the first support plate is supported on the bottom of the pressure tank. The support plate is provided on one side of the first support vertical plate, and a second support vertical plate is provided on the top of the support plate. The second support vertical plate is provided with a second support plate on the top of the second support vertical plate, and the second support plate is supported on the bottom of the nozzle at the end of the pressure tank. The utility model provides a first waist hole on the first support vertical plate, and the end of the support plate is connected to the first waist hole through a connecting ear, so that the second support plate can be adjusted in height according to the height of the nozzle;

[0004] Although it is possible to support the outlet nozzle of the pressure vessel, there are still some problems in daily use. When dealing with the outlet nozzles of pressure vessels of different heights, different diameters and different supporting positions, it is necessary to remove the bolts in sequence, and then move the corresponding support plate, the first support plate, the first support vertical plate, the second support plate and the second support vertical plate to the specified position, and finally screw in the nuts one by one. This method is time-consuming and labor-intensive when supporting the outlet nozzles of large quantities of pressure vessels, and is not convenient and quick, thereby increasing invalid working hours and reducing efficiency. In addition, the first waist hole and the connecting ear are connected by bolts. When the support plate is subjected to force, it is very easy for the support plate to slide down and cause support failure. Utility Model Content

[0005] In view of this, the utility model provides a supporting device for the outlet nozzle of a pressure vessel, which can be quickly adjusted according to the actual position of the outlet nozzle of the pressure vessel through the supporting mechanism, ensuring that the supporting mechanism can effectively support the gravity load of the outlet nozzle of the pressure vessel and the medium inside it, solving the problem of increased ineffective working hours caused by the need to screw in nuts and bolts one by one when tightening bolts, and can significantly save assembly time when supporting the outlet nozzles of large quantities of pressure vessels, thereby improving the work efficiency of the staff to a certain extent.

[0006] In order to solve the above technical problems, the utility model provides a supporting device for an outlet nozzle of a pressure vessel, comprising a base plate and a supporting mechanism arranged on the front surface of the base plate, the supporting mechanism comprising a guide rail arranged on the front surface of the base plate, a slider being slidably connected in the guide rail, a rectangular tube being provided on the upper surface of the slider, a rectangular barrel being slidably connected in the rectangular tube, an arc-shaped supporting plate being movably inserted in a slot arranged on the upper end of the front surface of the rectangular barrel, a screw rod being rotatably connected in a rotating hole arranged in the middle of the slider, the upper end of the screw rod being threadedly connected to the rectangular barrel, and a limiting component for limiting the screw rod is also provided in the middle of the lower surface of the slider.

[0007] The support mechanism also includes a socket arranged in the middle of the lower end of the arc-shaped support plate, a locking bolt is movably inserted in the socket, and the rear end of the locking bolt is threadedly connected to the threaded hole arranged on the rear wall of the slot; the support mechanism also includes through slots that are laterally symmetrically arranged on the left and right surfaces of the guide rail, and the screw holes that are laterally symmetrically arranged in the middle of the left and right surfaces of the slider are both threadedly connected with fixing bolts, and the fixing bolts are respectively arranged in cooperation with the adjacent through slots on the same side.

[0008] The limiting assembly includes a rectangular groove arranged on the lower end surface of the screw rod, a rectangular sliding cylinder is slidably connected in the rectangular groove, and a circular plate is provided on the lower surface of the rectangular sliding cylinder; the limiting assembly includes a spring arranged between the top wall surface of the rectangular groove and the bottom wall surface of the rectangular sliding cylinder; the limiting assembly also includes an annular ratchet plate arranged at the edge of the upper end surface of the circular plate, a limiting tooth groove ring plate is provided in the middle part of the lower surface of the slider, and the limiting tooth groove ring plate and the annular ratchet plate are arranged in cooperation with each other.

[0009] An operating rod is arranged on the lower end surface of the circular plate.

[0010] The beneficial effects of the above technical solution of the utility model are as follows:

[0011] 1. The relevant staff will fix the bottom plate and its accessories to the designated installation site, and then slide the slider and its accessories according to the appropriate position required to be supported by the pressure vessel outlet nozzle, until the arc support plate moves to the position directly below the pressure vessel outlet nozzle required to support the position, and then the relevant staff will tighten the fixing bolts to fix the slider and its accessories. After that, the relevant staff will turn the circular plate, and the rotation of the circular plate will drive the annular ratchet plate, rectangular groove, screw and spring to rotate synchronously. When the screw rotates, it drives the rectangular screw barrel, arc support plate and locking bolt to move upward synchronously until the arc support plate tightly contacts the pressure vessel outlet nozzle, and then stop rotating the circular plate. It can be quickly adjusted according to the actual position of the pressure vessel outlet nozzle to ensure that the support mechanism can effectively support the gravity load of the pressure vessel outlet nozzle and its internal medium.

[0012] 2. During the rotation of the annular ratchet plate, the annular ratchet plate will slide relative to the limit tooth groove ring plate. When the ratchet on the annular ratchet plate slides with the inclined surface of the ratchet groove on the limit tooth groove ring plate, the annular ratchet plate will continuously overcome the elastic force of the spring to drive the circular plate and the rectangular sliding cylinder to move down along the rectangular groove. When the ratchet on the annular ratchet plate moves to the next ratchet groove on the limit tooth groove ring plate, the annular ratchet plate will use the spring rebound force to drive the circular plate and the rectangular sliding cylinder to reset along the rectangular groove. This process is repeated continuously when the annular ratchet plate rotates. When the arc-shaped support plate tightly contacts the outlet nozzle of the pressure vessel, the ratchet on the annular ratchet plate will contact the limit tooth The ratchet grooves corresponding to the groove ring plates are arranged in a one-to-one correspondence, so as to limit the screw rod and its auxiliary mechanisms. When disassembly is required, it is only necessary to move the circular plate downward, and the circular plate, annular ratchet plate, circular plate and rectangular sliding cylinder will overcome the elastic force of the spring and move downward along the rectangular groove, and finally the annular ratchet plate is separated from the limiting tooth groove ring plate, and then the circular plate can be reversed. The supporting mechanism can be quickly locked and unlocked, which solves the problem of increased invalid working hours caused by the need to screw in nuts and bolts one by one when tightening bolts. It can significantly save assembly time when supporting the outlet nozzles of large quantities of pressure vessels, and improve the work efficiency of the staff to a certain extent.

[0013] 3. When facing pressure vessel outlet nozzles with different diameters, you only need to unscrew the locking bolt, then replace the corresponding arc support plate, and reset the locking bolt, which meets the need for supporting pressure vessel outlet nozzles with different diameters.

Figure 1-4 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0020] like Figure 1-4 As shown:

[0021] The present embodiment provides a support device for an outlet nozzle of a pressure vessel, comprising a base plate 100 and a support mechanism arranged on the front surface of the base plate 100, the support mechanism comprising a guide rail 200 arranged on the front surface of the base plate 100, a slider 201 being slidably connected in the guide rail 200, a rectangular tube 202 being arranged on the upper surface of the slider 201, a rectangular screw barrel 203 being slidably connected in the rectangular tube 202, an arc-shaped support plate 204 being movably inserted in a slot arranged on the upper end of the front surface of the rectangular screw barrel 203, a screw rod 206 being rotatably connected in a rotating hole arranged in the middle of the slider 201, the upper end of the screw rod 206 being threadedly connected to the rectangular screw barrel 203, and a limiting component for limiting the screw rod 206 being further arranged in the middle of the lower surface of the slider 201; the support mechanism also comprises a socket arranged in the middle of the lower end of the arc-shaped support plate 204, a locking bolt 205 being movably inserted in the socket, and the rear end of the locking bolt 205 being threadedly connected to a threaded hole arranged on the rear wall of the socket.

[0022] like Figure 1-3 As shown, the support mechanism also includes through slots 300 that are laterally symmetrically arranged on the left and right surfaces of the guide rail 200, and the screw holes that are laterally symmetrically arranged in the middle of the left and right surfaces of the slider 201 are threadedly connected with fixing bolts 301, and the fixing bolts 301 are respectively arranged in cooperation with the adjacent through slots 300 on the same side.

[0023] like Figure 1-3 As shown, the limit assembly includes a rectangular groove 400 arranged on the lower end surface of the screw rod 206, a rectangular sliding cylinder 401 is slidably connected in the rectangular groove 400, and a circular plate 402 is provided on the lower surface of the rectangular sliding cylinder 401; the limit assembly includes a spring 405 arranged between the top wall surface of the rectangular groove 400 and the bottom wall surface of the rectangular sliding cylinder 401; the limit assembly also includes an annular ratchet plate 403 arranged at the edge of the upper end surface of the circular plate 402, and a limit tooth groove ring plate 404 is provided in the middle part of the lower surface of the slider 201, and the limit tooth groove ring plate 404 and the annular ratchet plate 403 are arranged in cooperation with each other.

[0024] The working principle of a support device for a pressure vessel outlet nozzle provided by the utility model is as follows: first, the relevant staff fixes the bottom plate 100 and its accessories to the designated installation site, and then slides the slider 201 and its accessories according to the appropriate position required to be supported by the pressure vessel outlet nozzle, until the arc-shaped support plate 204 moves to the position directly below the pressure vessel outlet nozzle required to be supported, and then the relevant staff tightens the fixing bolt 301 to fix the slider 201 and its accessories, and then the relevant staff twists the circular plate 402, and the rotation of the circular plate 402 drives the annular ratchet plate 403, the rectangular groove 400, the screw rod 206 and the spring 405 to rotate synchronously, and the screw rod 206 rotates when rotating. The rectangular screw barrel 203, the arc-shaped support plate 204 and the locking bolt 205 are driven to move upward synchronously until the arc-shaped support plate 204 is tightly against the outlet nozzle of the pressure vessel, and then the rotation of the circular plate 402 is stopped. The circular plate 402 can be quickly adjusted according to the actual position of the outlet nozzle of the pressure vessel to ensure that the supporting mechanism can effectively support the gravity load of the outlet nozzle of the pressure vessel and the medium inside it. During the rotation of the annular ratchet plate 403, the annular ratchet plate 403 will slide relative to the limiting tooth groove ring plate 404. When the ratchet on the annular ratchet plate 403 slides with the inclined surface of the ratchet groove on the limiting tooth groove ring plate 404, the annular ratchet plate 403 will continuously overcome the elastic force of the spring 405 to drive the circular plate 402 and the rectangular sliding barrel 40 1 moves down along the rectangular groove 400, and when the ratchet on the annular ratchet plate 403 moves to the next ratchet groove on the limiting tooth groove ring plate 404, the annular ratchet plate 403 will use the spring 405 rebound force to drive the circular plate 402 and the rectangular sliding cylinder 401 to reset along the rectangular groove 400. This process is repeated continuously when the annular ratchet plate 403 rotates. When the arc support plate 204 tightly contacts the outlet nozzle of the pressure vessel, the ratchet on the annular ratchet plate 403 will be arranged in a one-to-one correspondence with the ratchet groove corresponding to the limiting tooth groove ring plate 404, thereby limiting the screw rod 206 and its auxiliary mechanism. When disassembly is required, it is only necessary to move the circular plate 402 downward, and the circular plate 402, the annular ratchet plate 403, the circular plate 402 and the rectangular sliding cylinder 4 01 will overcome the elastic force of spring 405 and move downward along the rectangular groove 400, eventually separating the annular ratchet plate 403 from the limiting tooth groove ring plate 404, and then the circular plate 402 can be reversed, which can quickly lock and unlock the supporting mechanism, solving the problem of increasing invalid working hours due to the need to screw in nuts and bolts one by one when tightening bolts, and can significantly save assembly time when supporting a large number of pressure vessel outlet nozzles, thereby improving the work efficiency of the staff to a certain extent. When facing pressure vessel outlet nozzles of different diameters, it is only necessary to unscrew the locking bolt 205, and then replace the corresponding arc support plate 204, and reset the locking bolt 205, thereby meeting the need to support pressure vessel outlet nozzles of different diameters.

[0025] like Figure 2-3 As shown, an operating rod 500 is provided on the lower end surface of the circular plate 402 to facilitate operation by relevant staff.
