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 transporting frame for cementing. Background Art

[0002] During cementing operations, in order to improve the uniformity of cement slurry density, the cement ash is directly transported to the mixing system through the ash delivery pipeline, which causes uneven ash delivery and poor ash delivery, resulting in the cement slurry density reaching the required level for cementing operations. This problem not only affects the quality of cementing construction, but also poses a greater risk of well control. At present, cement trucks and cementing mixing skids use constant pressure ash delivery tanks to supply ash, and use gas to pressurize the constant pressure ash delivery tanks. When the pressure in the tank reaches a certain value, the cement ash particles are transported from the constant pressure ash delivery tanks to the mixing systems of cement trucks and cementing mixing skids.

[0003] At present, the ash conveying tanks used in domestic marine cementing are generally 2 cubic meters of constant pressure tanks. With the continuous increase in the operating water depth, the 2 cubic meters of constant pressure ash conveying tanks cannot meet the requirements of cementing construction. Due to the limitations of transportation conditions, the diameter of the constant pressure tanks above 2 cubic meters cannot be increased indefinitely, and the height often exceeds the limit. Over-height transportation has become one of the important sources of road safety and damage to road infrastructure.

[0004] After investigation, it was found that some constant pressure tanks are still placed vertically on the table of the transport vehicle, and the problem of super-high transportation of constant pressure tanks has not been solved. Some transport racks are welded to the constant pressure tanks. When the constant pressure tanks are moved from the cementing construction work station to the transport vehicle table, or from the transport vehicle table to the cementing construction work station, a special crane is required. Due to the change in the center of gravity of the constant pressure tank, it is easy to cause the constant pressure tank to slip and damage the pipelines around the constant pressure tank during operation. In addition, the size of the transport rack is relatively fixed, and it can only transport constant pressure tanks of fixed sizes, but not other tanks at the cementing construction 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, and the current transport racks need to rely on special cranes and the size of the transport racks is relatively fixed, and can only transport constant-pressure tanks of one specification, but cannot transport other tanks at the cementing construction site.

[0034] The present invention is 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 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 vertically mounted on 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 of two adjacent teeth of the stop rail 3, and the radius r of the positioning arc of the roller of the stop rail 3 satisfies r=0.505d1, where d1 is the diameter of the transverse telescopic rod 9-2. This ensures that a transverse telescopic rod 9-2 is engaged with the stop rail 3 each time. The telescopic arc frame 9 also includes a load-bearing plate 9-4, which is arranged in the arc section of the two telescopic arc rods 9-3. The two end surfaces of the load-bearing plate 9-4 are respectively fixed to the two telescopic arc rods 9-3, and the load-bearing plate 9-4 is perpendicular to the longitudinal telescopic rod 9-1. According to the needs of the on-site construction work, the arrangement angle of the load-bearing plate 9-4 can be adjusted. A tightening belt 11 is provided on the telescopic arc frame 9, and the tightening belt 11 is used to tie the tank body to the telescopic arc frame 9.

[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 a hydraulic cylinder base 5-1.

When the plug cavity of the hydraulic cylinder piston rod 5-4 is filled with oil, the hydraulic oil enters the rod cavity through the thin-walled holes 5-2-2. The presence of the thin-walled holes 5-2-1 can turn the single-acting hydraulic cylinder 5 into a double-acting hydraulic cylinder. When the hydraulic cylinder piston rod 5-4 retracts, the presence of the thin-walled holes 5-2-1 slows down the movement speed of the tank. An annular sealing ring 5-2-2 is provided between the outer wall of the larger cross-section 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 conveying and transporting rack for cementing, and its working principle is as follows:

[0041] According to the height of the constant pressure tank, the height between the longitudinal telescopic rod 9-1 and the telescopic arc rod 9-3 in the telescopic arc frame 9 is adjusted. Similarly, according to the diameter of the constant pressure tank, the length of the transverse telescopic rod 9-2 is adjusted. Then the angle of the load-bearing plate 9-4 in the two telescopic arc rods 9-3 is adjusted, and then the load-bearing plate 9-4 of a certain angle is welded between the two telescopic arc rods 9-3. After the telescopic arc frame 9 is assembled, the fixed seat 2, the stop rail 3 and the limit block 4 and other components are welded on the base in sequence. The telescopic arc frame 9 is placed between the two limit blocks 4, and the limit block 4 or the lifting ear seat 1 is used to prevent the telescopic arc frame 9 from slipping during the rolling process. The first single-ear suspension rod 10-1, the second single-ear suspension rod 10-2 and the connecting block 10-3 are hinged, and the constant pressure tank can be folded at this time. In order to prevent the constant pressure tank from shaking in the telescopic arc frame 9, the tightening belt 11 is increased or decreased according to the relative height of the constant pressure tank and the telescopic arc frame 9. When the constant pressure tank is loaded, in the upright state of the constant pressure tank, the first single-ear suspension rod 10-1 and the second single-ear suspension rod 10-2 are hinged to the through holes at the end of the connecting block 10-3 through the through holes opened on themselves, so as to fix and support the constant pressure tank.
