Description

Technical Field

[0001] The utility model belongs to the technical field of oil drilling rigs, and particularly relates to a noise reduction partition wall. Background Art

[0002] The H-shaped steel is an economic section high-efficiency profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving, and light structural weight in all directions. It has been widely used in oil extraction equipment. Since large equipment such as drilling rigs used in oil extraction often need to be transported, the H-shaped steel members used during transportation may be deformed due to force extrusion. For safety reasons, correction is required.

[0003] In the existing correction operation, generally, a roller-shaped device is used by manual workers to reciprocally roll the inner side of the H-shaped steel member at the drilling rig moving site to restore its correction. Therefore, the labor intensity is relatively large and the efficiency is low. Content of the Utility Model

[0004] The purpose of the utility model is to provide a noise reduction partition wall, which has a simple structure, is convenient for storage and opening, and is also convenient for installation and carrying. It can automatically correct the H-shaped steel member, effectively improving the operation efficiency during the use of the drilling rig.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a noise reduction partition wall, which is composed of a first wall panel, a fence and a second wall panel. After the first wall panel, the fence and the second wall panel are inserted and connected, they are fixed by screws. A keel is arranged inside the fence, and a slide bar is installed by screws at the protruding end of the keel. Uniform through holes are arranged on the side surface of the second wall panel. Slide grooves are arranged on the inner wall of the fence, and the slide grooves are symmetrically arranged about the middle of the fence. A plurality of slide grooves are arranged along the height direction of the fence. A corrugated board is slidably connected inside two symmetrically arranged slide grooves, and sound insulation cotton is filled between the upper and lower corrugated boards.

[0006] Further, threaded columns are fixed on the side surface of the first wall panel. The threaded columns are arranged at the four corners of the first wall panel, and there are four in total.

[0007] Further, insertion holes are arranged on the baffle, and the insertion holes correspond to the positions of the threaded columns.

[0008] Further, sunken holes are arranged on the second wall panel, fastening screws are placed inside the sunken holes, and the fastening screws are fixedly connected with the threaded columns in a threaded manner.

[0009] Further, through grooves are arranged on the corrugated board for the keel to pass through.

[0010] The beneficial effects of the utility model are:

[0011] 1. Use a bracket and set several corrective steel wheels inside the bracket. The structure is simple. By driving the corrective steel wheels with a motor, the H-shaped steel members can be automatically corrected.

[0012] 2. Set multiple brackets to meet the correction of H-shaped steel members with different length specifications. At the same time, the brackets are connected by a scissor-type connecting frame, which is convenient for the storage and carrying of the overall correction structure. At the same time, the bottom plate provided at the bottom of the bracket is convenient for the installation and disassembly of the overall correction structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to further understand the content, features and effects of the present utility model, the following embodiments are exemplified and described in detail in conjunction with the accompanying drawings.

[0017] Please refer to Figures 1 to 2 simultaneously. The noise reduction partition wall of the embodiment of the present utility model will be described in detail below with reference to the accompanying drawings.

[0018] As Figure 1 shown, the noise reduction partition wall is composed of a first wall panel 1, an enclosure 2 and a second wall panel 3. After the first wall panel 1, the enclosure 2 and the second wall panel 3 are inserted, they are fixed by screws. A keel 4 is penetrated inside the enclosure 2, and a slide bar 5 is installed by screws at the penetrated end of the keel 4. Uniformly distributed through holes 6 are provided on the side surface of the second wall panel 3. Chutes 7 are provided on the inner wall of the enclosure 2. The chutes 7 are symmetrically arranged about the middle of the enclosure 2. A number of chutes 7 are provided along the height direction of the enclosure 2. A corrugated board 8 is slidably connected inside two symmetrically arranged chutes 7, and sound insulation cotton is filled between the upper and lower corrugated boards 8.

[0019] A threaded column 9 is fixed on the side surface of the first wall panel 1. The threaded column 9 is arranged at the four corners of the first wall panel 1, and there are four in total. Insertion holes 10 are provided on the baffle, and the insertion holes 10 correspond to the positions of the threaded columns 9. Sunk holes 11 are provided on the second wall panel 3, and fastening screws 12 are placed inside the sunk holes 11. The fastening screws 12 are fixedly connected with the threaded columns 9 in a threaded manner. Through grooves 13 are provided on the corrugated board 8, and the through grooves 13 are for the keel 4 to pass through.
