Constant pressure ash transport rack for cementing

Abstract

The present invention discloses a constant pressure ash conveying and transporting frame for cementing, comprising a telescopic arc frame body, a base fixing module and a telescopic support module. The longitudinal section of the telescopic arc frame body is in the shape of a "J". The telescopic arc frame body and the telescopic support module are both arranged above the base fixing module. The arc section of the telescopic arc frame body is engaged with the base fixing module. The straight section of the telescopic arc frame body is hinged to one end of the telescopic support module, and the other end of the telescopic support module is hinged to the base fixing module. The constant pressure ash conveying and transporting frame for cementing of the present invention solves the problem that ultra-high transportation affects road safety and damages road infrastructure. During the entire operation process, no special crane is required, which avoids the constant pressure tank from slipping due to the change in the center of gravity of the constant pressure tank during the lifting process, thereby avoiding major safety accidents caused by the constant pressure tank. The longitudinal and transverse dimensions of the transport frame are adjustable, which solves the problem that the current transport frame can only transport constant pressure tanks of one specification, but cannot transport other tanks at the cementing operation site.

Description

Technical Field

[0001] The invention belongs to the technical field of cementing ash conveying equipment and relates to a constant-pressure ash conveying and transportation rack for cementing. Background Art

[0002] During cementing operations, to improve the uniformity of cement slurry density, the problem of uneven ash distribution and poor ash distribution, resulting in insufficient cement slurry density, occurs when cement ash is directly delivered to the mixing system through ash delivery pipelines. This problem not only affects cementing quality but also poses a significant risk to well control. Currently, cement slurry mixing in cement trucks or cementing mixing skids uses constant-pressure ash delivery tanks. These tanks are pressurized with gas, and when the pressure in the tank reaches a certain level, the tanks deliver cement ash particles to the mixing system of the cement truck or cementing mixing skid.

[0003] Currently, the ash delivery tanks used in domestic marine cementing are generally 2-cubic-meter constant-pressure tanks. As operating water depths continue to increase, these tanks are no longer sufficient for cementing operations. Due to transportation limitations, the diameter of constant-pressure tanks larger than 2 cubic meters cannot be increased indefinitely, often exceeding the height limit. This excessive height has become a major source of damage to road safety and infrastructure.

[0004] After investigation, it was found that some constant pressure tanks are still placed vertically on the platform of the transport vehicle, and the problem of excessively high transport of constant pressure tanks remains unresolved. Some transport racks are welded to the constant pressure tank. A dedicated crane is required to move the constant pressure tank from the cementing operation station to the transport vehicle platform, or vice versa. Due to the constant pressure tank's shifting center of gravity, it can easily slip during operation, damaging surrounding pipelines. Furthermore, the transport racks are of fixed size and can only transport constant pressure tanks of a fixed size, not other tanks at the cementing operation site. Summary of the Invention

[0005] The purpose of the present invention is to provide a constant pressure ash transport rack for cementing, which solves the problem that the constant pressure tank exceeds the height limit and affects the road transportation safety; the current transport rack needs to rely on a special crane and the transport rack is relatively fixed in size, and can only transport constant pressure tanks of one specification, but cannot transport other tanks at the cementing construction site.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] The present invention provides a constant pressure ash transport rack for cementing, such as Figure 1 As shown, it includes a telescopic arc frame 9, a base fixing module 7 and a telescopic support module 8. The longitudinal section of the telescopic arc frame 9 is in the shape of a "J". The telescopic arc frame 9 and the telescopic support module 8 are both arranged above the base fixing module 7. The arc section of the telescopic arc frame 9 is engaged with the base fixing module 7. The straight section of the telescopic arc frame 9 is hinged to one end of the telescopic support module 8, and the other end of the telescopic support module 8 is hinged to the base fixing module 7.

[0036] like Figure 5As shown, the base fixing module 7 includes a fixing base 2, which is columnar. Four lifting lugs 1 are provided around the upper end surface of the fixing base 2. The four lifting lugs 1 are symmetrical along the central axis of the upper end surface of the fixing base 2, making the lifting lugs 1 convenient for lifting. The base fixing module 7 also includes two stop rails 3, which are provided between the two lifting lugs 1 along the length of the fixing base 2. The two stop rails 3 are symmetrical along the central axis of the upper end surface of the fixing base 2, and a number of limit blocks 4 are evenly installed on the stop rails 3. The telescopic support module 8 includes two hydraulic cylinders 5, which are symmetrical along the central axis of the upper end surface of the fixing base 2. One end of the two hydraulic cylinders 5 is respectively hinged to the upper end surface of the fixing base 2, and the other end of the two hydraulic cylinders 5 is respectively hinged to two longitudinal telescopic rods 9-1. The telescopic support module 8 also includes two locking rods 10, which are symmetrical along the central axis of the upper end surface of the fixed base 2. One end of each locking rod 10 is hinged to the upper end surface of the fixed base 2, and the other end of each locking rod 10 is hinged to the ends of the lateral telescopic 9-2. The telescopic support module 8 also includes two support bases 6, which are arranged on the upper end surface of the fixed base 2, adjacent to the locking rods 10, and symmetrical along the central axis of the upper end surface of the fixed base 2.

[0037] like Figure 6 As shown, the telescopic arc frame 9 includes two longitudinal telescopic rods 9-1 and several transverse telescopic rods 9-2. The two longitudinal telescopic rods 9-1 are arranged in parallel, and the several transverse telescopic rods 9-2 are arranged in parallel. The transverse telescopic rods 9-2 are mounted perpendicularly to the side walls of the two longitudinal telescopic rods 9-1. The telescopic arc frame 9 also includes two telescopic arc rods 9-3. The telescopic arc rods 9-3 have a "J" shape in longitudinal cross-section. The two telescopic arc rods 9-3 are arranged in parallel, and the transverse telescopic rods 9-2 are mounted perpendicularly to the side walls of the two telescopic arc rods 9-3. The two longitudinal telescopic rods 9-1 are respectively inserted into the straight sections of the two telescopic arc rods 9-3. The longitudinal telescopic rods 9-1 are slidably connected to the straight sections of the telescopic arc rods 9-3. Transverse telescopic rods 9-2 are evenly installed in the arc section between the two telescopic arc rods 9-3, and the transverse telescopic rods 9-2 are mounted perpendicularly to the side walls of the two telescopic arc rods 9-3. The chord length between two adjacent transverse telescopic rods 9-2 is equal to the pitch p between two adjacent teeth of the stop rail 3. The radius r of the positioning arc of the roller of the stop rail 3 satisfies the following formula: r = 0.505d1, where d1 is the diameter of the transverse telescopic rod 9-2. This ensures that one transverse telescopic rod 9-2 engages the stop rail 3 at all times. The telescopic arc frame 9 also includes a bearing plate 9-4, which is disposed within the arc segments of the two telescopic arc rods 9-3. The end surfaces of the bearing plate 9-4 are respectively fixedly connected to the two telescopic arc rods 9-3. The bearing plate 9-4 is perpendicular to the longitudinal telescopic rod 9-1. The arrangement angle of the bearing plate 9-4 can be adjusted according to the needs of on-site construction operations. The telescopic arc frame 9 is provided with a tightening belt 11, which is used to tie the tank body to the telescopic arc frame 9.

[0038] like Figure 7 As shown, the locking rod 10 includes a first single-ear suspension rod 10-1, a second single-ear suspension rod 10-2 and a connecting plate 10-3. A plurality of through holes are provided on the connecting plate 10-3. One end of the first single-ear suspension rod 10-1 is hinged to the connecting plate 10-3, and one end of the second single-ear suspension rod 10-2 is hinged to the connecting plate 10-3. The first single-ear suspension rod 10-1 and the second single-ear suspension rod 10-2 are provided with through holes corresponding to the through holes at both ends of the connecting plate 10-3.

[0039] like Figure 8 As shown, the hydraulic cylinder 5 includes a hydraulic cylinder barrel 5-3, which is in the shape of a hollow cylinder. One end of the hydraulic cylinder barrel 5-3 is fixedly connected to the hydraulic cylinder base 5-1. The other end of the hydraulic cylinder barrel 5-3 is inserted into the hydraulic cylinder plunger 5-2 and the hydraulic cylinder piston rod 5-4. The hydraulic cylinder plunger 5-2 is in the shape of a hollow cylinder with a variable cross-section. The hydraulic cylinder piston rod 5-4 is in the shape of a hollow cylinder. The hydraulic cylinder plunger 5-2 is fixedly connected to one end of the hydraulic cylinder piston rod 5-4. The hydraulic cylinder plunger 5-2 is arranged close to the hydraulic cylinder base 5-1. The hydraulic cylinder barrel 5-3 is slidably connected to the hydraulic cylinder plunger 5-2. The outer diameter of the larger cross-section of the hydraulic cylinder plunger (5-2) is consistent with the inner diameter of the hydraulic cylinder barrel (5-3), and the inner diameter of the cross-section of the hydraulic cylinder plunger (5-2) is consistent with the inner diameter of the hydraulic cylinder piston rod (5-4). The smaller cross-sectional section of the hydraulic cylinder plunger 5-2 is circumferentially and evenly defined with thin-walled holes 5-2-1 perpendicular to the centerline. These holes connect the rod cavity and the plunger cavity of the hydraulic cylinder piston rod 5-4. When oil enters the plunger cavity of the hydraulic cylinder piston rod 5-4, the oil flows into the rod cavity through the thin-walled holes 5-2-2. The presence of these holes 5-2-1 transforms the single-acting hydraulic cylinder 5 into a double-acting one. When the hydraulic cylinder piston rod 5-4 retracts, the thin-walled holes 5-2-1 slow down the cylinder's movement. An annular sealing ring 5-2-2 is provided between the outer wall of the larger cross-sectional section of the hydraulic cylinder plunger 5-2 and the inner wall of the hydraulic cylinder barrel 5-3.

[0040] The present invention provides a constant pressure ash transport rack for cementing, the working principle of which is as follows:

[0041] Adjust the height between the longitudinal telescopic rods 9-1 and 9-3 in the telescopic arch frame 9 according to the height of the constant pressure tank. Similarly, adjust the length of the transverse telescopic rod 9-2 according to the diameter of the constant pressure tank. Then, adjust the angle of the load-bearing plate 9-4 within the two telescopic arch rods 9-3 and weld the load-bearing plate 9-4 at a certain angle between the two telescopic arch rods 9-3. After the telescopic arch frame 9 is assembled, weld the fixing base 2, stop rail 3, and limit block 4 to the base in sequence. Place the telescopic arch frame 9 between the two limit blocks 4. The limit blocks 4 or lifting lugs 1 prevent the telescopic arch frame 9 from sliding during rolling. A first single-ear suspension rod 10-1, a second single-ear suspension rod 10-2, and a connecting block 10-3 are hinged together, allowing the constant pressure tank to fold. To prevent the constant pressure tank from shaking within the telescopic arch frame 9, add or remove the tightening strap 11 according to the relative height between the constant pressure tank and the telescopic arch frame 9. When the constant pressure tank is loaded, in the upright state, the first single-ear suspension rod 10-1 and the second single-ear suspension rod 10-2 are hinged to the end through-hole of the connecting block 10-3 through the through-holes opened on themselves, so as to fix and support the constant pressure tank.
