Description

Technical Field

[0001] The utility model relates to the technical field of release racks, in particular to a portable release rack dedicated for low-voltage replacement. Background Art

[0002] During the jointing of new gas pipelines, a bleed pipe is typically connected from the bleed valve inside the valve well to the outside of the valve well for bleed and replacement work. The bleed pipe is typically made of steel pipe. Due to its inherent weight, the gas valve well is typically several meters deep, and the portion of the wellhead that extends three meters above the wellhead can weigh tens of kilograms. During gas construction and installation, the bleed pipe is often simply secured at the wellhead using a piece of wood placed horizontally and tied with steel wire. While this simple solution can temporarily solve the problem of pipeline swaying due to pressure during bleed, the weight of the bleed pipe puts significant stress on the bleed valve connected to the valve well, which can cause the bleed valve to break and easily cause personal injury, posing a significant safety hazard.

[0003] Currently, some specialized sling racks for low-pressure replacement are in use. However, these racks generally have a simple structure. While they provide a certain degree of support, the effect is short-lived. Furthermore, they are often quite tall, making transportation difficult. Furthermore, the bottom portion of the sling rack, which is submerged in the soil, is not sufficiently secure. In actual use, it can easily sink into the soil or become misaligned or tilted. Once these problems occur, they pose significant safety risks, potentially impacting construction progress and even posing a serious threat to the lives of construction workers. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides a portable low-pressure replacement special discharge rack which is easy to carry on a vehicle, has high safety, is not easy to sink into the mud or move, and has a good fixing effect on the discharge pipe.

[0005] In order to solve the above-mentioned technical problems, the technical solution proposed by the utility model is: a portable low-pressure replacement special release rack, including a bottom cylinder, a support column with adjustable depth is provided in the bottom cylinder, oblique support legs are equidistantly provided under the bottom cylinder, a base plate is connected under the support legs, an inverted square platform with a larger top and a smaller bottom is provided under the base plate, a square plate is fixedly connected to the top of the support column, a lower semicircular pipe clamp is fixed on the square plate by bolts, and an upper semicircular pipe clamp is fixed on the lower semicircular pipe clamp by bolts.

[0006] Furthermore, the base tube is provided with equally spaced positioning holes, into which positioning bricks are inserted. The support columns are placed atop the positioning bricks, and a gap is provided between the support columns and the base tube. By coordinating the positioning holes and the positioning bricks, the height of the support columns within the base tube can be flexibly adjusted to meet different usage requirements. This gap arrangement makes the adjustment process smoother and more convenient.

[0007] Furthermore, the joints between the positioning square holes and the positioning square bricks are sealed with cement; the joints between the bottom tube and the support column are sealed with cement. Using cement to seal the joints can enhance the stability of the entire structure, prevent the support column from shaking during use, and improve the safety of the rack.

[0008] Furthermore, the upper and lower semicircular pipe clamps are both bolted together with high-strength ceramic lining washers. These high-strength ceramic lining washers protect the vent pipe, reducing friction and wear between the clamp and the pipe, thereby extending the pipe's service life. Furthermore, the ceramic material offers excellent high-temperature and corrosion resistance, making it suitable for a variety of harsh working environments.

[0009] Furthermore, the four corners of the foundation plate are provided with round holes for installing positioning piles. Installing positioning piles through the round holes can further enhance the stability of the dispersing frame, prevent the dispersing frame from deflecting or tilting during use, and ensure construction safety.

[0010] Furthermore, a first positioning mark is provided at the upper end of the front of the bottom tube, and a second positioning mark is provided at the front of the support column. The first and second positioning marks can help the user accurately adjust the height of the support column, thereby improving the accuracy and efficiency of the operation.

[0011] Furthermore, a gasket is provided at the joint between the lower semicircular pipe clamp and the upper semicircular pipe clamp. The gasket can play a role of buffering and sealing, reducing the vibration of the discharge pipe in the pipe clamp, preventing gas leakage, and improving the safety and reliability of the discharge rack.

[0012] Furthermore, a counterweight cylinder for placing counterweights is connected to the base plate, and a water-permeable hole is provided in the base plate below the counterweight cylinder. The counterweight cylinder can be used to place counterweights as needed, thereby increasing the stability of the decentralization rack. The water-permeable hole prevents water accumulation, which can corrode or damage the base plate.

[0013] Furthermore, a square plug-in cylinder is provided on the front side of the foundation plate, and a scaled settlement observation plate is inserted into the square plug-in cylinder of the crushing chamber. The scaled settlement observation plate can monitor the settlement of the foundation in real time, promptly identify potential safety hazards, and ensure the stable operation of the dispersing rack.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] This portable, low-pressure replacement venting stand offers numerous significant advantages. First, it's easy to transport in vehicles. Its components are well-designed and quickly assembled. Once assembled, it's relatively compact, requiring minimal vehicle space and easily transported between construction sites, significantly improving construction efficiency and convenience. Second, it offers high safety. The support columns within the base tube can be adjusted in height using positioning square holes and bricks to meet varying requirements. The joints are sealed with cement, enhancing structural stability and preventing the columns from wobbling. The support legs beneath the base tube connect to the foundation plate, which has circular holes at its four corners for mounting positioning stakes, further preventing the venting stand from shifting or tilting. High-strength ceramic linings within the pipe clamps protect the venting pipes and are both heat-resistant and corrosion-resistant. Gaskets at the joints between the pipe clamps prevent gas leakage, enhancing safety and reliability. Furthermore, it's resistant to sinking into the mud or shifting. An inverted cube platform, larger at the top and smaller at the bottom, is located beneath the foundation plate, enhancing ground contact stability. The counterweight cylinder, which can be loaded with weights as needed, further enhances the venting stand's stability and prevents it from sinking into the mud or shifting. Finally, the vent pipe has a good fixing effect. The lower semicircular pipe clamp and the upper semicircular pipe clamp on the square plate are fixed by bolts. The high-strength ceramic lining gasket on the inside reduces the friction and wear between the pipe clamp and the vent pipe. The gasket plays a buffering and sealing role, reducing the vibration of the vent pipe, and together ensure that the vent pipe is firmly fixed on the vent rack. BRIEF DESCRIPTION OF THE DRAWINGS
