Description

Technical Field

[0001] This utility model relates to conveying pipelines, and more particularly to a manual drive device for valves in shallow buried pipelines. Background Technology

[0002] Pipelines are commonly used conveying equipment in industrial production. In pipeline conveying systems, the flow direction of fluid is controlled by the opening and closing of valves. To protect the pipeline and save space, it is usually buried underground. In factories, pipelines are usually buried shallowly, at a depth of 1.2-1.5m, and inspection wells (manholes) are built. Valves are distributed in the inspection wells for easy operation and maintenance. For precise valve control, technicians in this field can choose to install electrically controlled valves, which can achieve real-time control. However, electrically controlled valves are more expensive. Considering cost issues, many valves are still manually controlled.

[0003] Operating the valves requires operators to go down into the maintenance well, which is a slow process. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a manual drive device for valves in shallow buried pipelines.

[0005] This utility model is achieved through the following technical solution: a manual drive device for a shallow buried pipeline valve, including a positioning frame set at the upper end of the inspection well. During use, the position between the positioning frame and the valve is fixed. The positioning frame is connected to a transmission structure. The lower end of the transmission structure can be connected to the valve. The upper end of the transmission structure is connected to a manual drive structure. The manual drive structure can drive the valve to move through the transmission structure.

[0006] Furthermore, the positioning frame includes a support frame that cooperates with the maintenance well, an extension frame is provided at the upper end of the support frame, the transmission structure extends upward to the upper side of the extension frame, and a rotating support structure that cooperates with the transmission structure is provided on the extension frame.

[0007] Furthermore, the support frame is provided with a second rotating support structure that cooperates with the transmission structure.

[0008] Furthermore, the transmission structure includes a transmission rod, which is connected to a speed reducer.

[0009] The advantages of this utility model are as follows: the positioning frame is installed at the top of the maintenance well, and the position between the positioning frame and the valve is fixed. The positioning frame is connected to the transmission structure, and the transmission structure is connected to the manual drive structure. Thus, the valve can be operated at the top of the maintenance well without having to go down into the maintenance well. The operating space is larger and the speed is faster.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0014] Example 1 like Figure 1-2As shown, a manual valve driving device for shallow buried pipelines is used to operate the manual valve of a conveying pipeline 2 installed in a maintenance well. It includes a positioning frame 7 for installation on the upper end of the maintenance well 1. In this embodiment, the positioning frame 7 includes a support frame that cooperates with the maintenance well 1. The support frame includes two parallel crossbeams 701. Concrete is laid on the outer edge of the upper end of the maintenance well 1 for hardening to obtain a hardened layer 6. During use, the position between the positioning frame 7 and the valve 3 is fixed. Specifically, the crossbeams 701 are mounted on the hardened layer 6 and fixed with ground bolts, or the crossbeams 701 and the valve 3 are fixed with connecting rods to prevent the positioning frame 7 from rotating.

[0015] A second rotary support structure is installed between the two crossbeams 701. The second rotary support structure includes a connecting beam 702 fixed between the two crossbeams 701. A bearing or bushing (not shown in the figure) is installed between the two connecting beams 702 to support the transmission rod.

[0016] The positioning frame 7 is connected to a transmission structure. The lower end of the transmission structure can be connected to the valve 3. Specifically, the transmission structure includes a transmission rod 5. The upper end of the transmission structure is connected to a manual drive structure. The manual drive structure can drive the valve 3 to move through the transmission structure. Specifically, the lower end of the transmission rod 5 is coaxially connected to the handle 4 of the valve 3. The manual drive structure uses an operating handle 13.

[0017] An extension frame 8 is fixed to the upper end of the support frame. In this embodiment, the extension frame 8 includes two parallel columns 801. The lower ends of the columns 801 are fixed to the crossbeam 701. A rotating support structure 1 that cooperates with the transmission structure is installed between the upper ends of the two columns 801. The rotating support structure 1 includes a support plate 802 fixed between the upper ends of the two columns 801. A reducer 9 is installed on the support plate 802. The upper end of the transmission rod 5 is connected to the reducer 9. An operating head 11 is integrally formed on the upper end of the reducer 9. The operating head 11 is prismatic. A slot that cooperates with the operating head 11 is machined on the operating handle 13. When not in use, the operating handle 13 is removed and stored to avoid loss or damage, and to prevent others from accidentally operating the valve 3. The reducer 9 can reduce the labor intensity of operating the valve 3. The extension frame controls the operating height, thereby reducing the labor intensity.

[0018] In this embodiment, the crossbeam 701, connecting beam 702, and column 801 are all made of channel steel, which is lightweight and has high structural strength. The main body of the transmission rod 5 is made of galvanized pipe, and the end is equipped with a connector, which is then connected to the handle 4 and reducer 9 through the connecting sleeve 10.

[0019] Example 2 like Figure 3-5As shown, a manual drive device for a shallow-buried pipeline valve 3 differs from Embodiment 1 in that the support frame is made in a disc shape to avoid upward protrusion under normal conditions. The support frame includes an outer support ring 703 that cooperates with the hardened layer 6. An inner support ring 704 is connected to the inner side of the outer support ring 703 via a connecting arm 708. A reducer 9 is connected to the inner support ring 704, and the upper end of the reducer 9 does not extend beyond the inner support ring 704. A baffle plate 705 is installed on the upper end of the outer support ring 703 and the inner support ring 704. The outer support ring 703, inner support ring 704 and connecting arm 708 are all made of channel steel. The outer support ring 703 is fixed to the hardened layer 6 by ground bolts. The outer support ring 703, inner support ring 704 and baffle plate 705 are fixed by welding. An operation port 707 that mates with the input shaft of the reducer 9 is machined in the middle of the baffle plate 705. 3-6 positioning ports 706 are machined at the edge of the baffle plate 705. The positioning ports 706 are located directly above the outer support ring 703.

[0020] In this embodiment, the riser 8 is movable. The support plate 802 is hinged with three downward-facing support legs 803. The lower ends of the support legs 803 can be inserted into the positioning port 706 and thus positioned by the positioning port 706. The lower ends of the support legs 803 are supported by the outer support ring 703. The transmission rod 12 is mounted through a bushing in the middle of the support plate 802. The transmission rod 12 can move up and down along the bushing. The upper end of the transmission rod 12 extends to the outside of the bushing and is connected to the operating handle 13. The lower end of the transmission rod 12 is detachably connected to the reducer 9 through a spline shaft.

[0021] When valve 3 needs to be operated, the entire riser 8 is placed on the upper side of the support frame, and the transmission rod 12 is connected to the reducer 9 for easy operation.

[0022] Example 3 like Figure 6 As shown, a manual drive device for a shallow-buried pipeline valve 3 differs from Embodiment 2 in that the shielding plate 705 includes an outer shielding ring 709 fixed on the outer support ring 703 and an inner shielding plate 711 fixed on the inner support ring 704. The outer shielding ring 709 and the inner shielding plate 711 are made of steel plates. The positioning port 706 is machined on the outer shielding ring 709, and the operation port 707 is machined on the inner shielding plate 711. An observation port is formed between the outer shielding ring 709 and the inner shielding plate 711, thereby enabling observation of the internal condition of the inspection well 1. A transparent plate 710 can be installed at the observation port. The transparent plate 710 is made of plexiglass.
