Description

Technical Field

[0001] The utility model relates to the technical field of natural gas extraction and transportation, and in particular to a metering pump transport device. Background Technology

[0002] In natural gas production and transportation projects, in order to prevent or slow down the corrosion of hydrogen sulfide on pipelines, it is often necessary to continuously add corrosion inhibitors to the acid gas pipeline to ensure the corrosion resistance of the acid gas pipeline; during the filling process, a diaphragm metering pump is required to pressurize and transport the gas. For example, for a gas field with 37 production sites, at least 140 metering pumps are required; and during the operation of the metering pump, due to equipment maintenance, fault handling and other reasons, the metering pump sometimes needs to be replaced, and the replaced metering pump needs to be transported to the maintenance point for maintenance or repair.

[0003] Currently, the transportation of metering pumps mainly adopts the process of moving them from or into the production area manually, and then using vehicles for transportation; however, the metering pump itself is heavy and small in size, and there are no other fixing points except the mounting holes at the base. As a result, during the manual transportation process, there is no foothold for the hands, which can easily cause slippage and fall accidents, causing personal injury and equipment damage. It is also difficult to fix the metering pump during the vehicle operation process, and it is easy to cause collision damage to the metering pump on rugged mountain roads. Contents of utility model

[0004] The purpose of the utility model is to provide a metering pump transporting device to overcome the shortcomings of the prior art that the metering pump lacks a fixed point, which makes it easy for the metering pump to fall or bump when being transported, thereby causing damage to the metering pump and injuries to personnel.

[0005] In a first aspect, the utility model provides a metering pump transport device, comprising:

[0006] A frame, on which a bracket, a fixing part and a handle assembly are arranged;

[0007] The bracket includes an arc-shaped support surface, and the diameter of the arc-shaped support surface matches the diameter of the pump head of the metering pump;

[0008] The fixing portion is located on one side of the bracket along the axial direction of the arc-shaped support surface, and the fixing portion includes a connecting hole, which is adapted to the mounting hole of the base of the metering pump;

[0009] The number of handle assemblies is at least two, and the handle assemblies are distributed on at least two opposite sides of the frame.

[0010] The arc-shaped support surface can be a complete arc or only a part of the arc, such as a semi-circular arc or a combination of multiple 1 / 6 arcs.

[0011] The connection holes are adapted to the mounting holes of the metering pump base. For example, the number, size, and distribution pitch of the connection holes are the same as those of the mounting holes of the metering pump base; or the size and distribution pitch of the connection holes are the same as those of the mounting holes of the metering pump base, but the number is less than that of the mounting holes of the metering pump base.

[0012] For the external shape of the metering pump in this solution, that is, it includes a base with mounting holes and a cylindrical pump head biased towards one side of the base, a metering pump handling device with a corresponding external shape is designed; when it is necessary to handle the metering pump, align the mounting holes on the metering pump base with the connection holes of the fixing part, and the metering pump can be connected to the rack through threaded connectors; then support the pump head on the arc-shaped support surface of the bracket, which can prevent the metering pump from tipping over due to unbalanced force; and the handle assembly can, on the one hand, serve as a force application point for the operator to facilitate manual handling during manual handling, making the manual handling operation easier and avoiding dropping accidents and the resulting personal injuries; on the other hand, it can serve as a fixing point for the bundling rope or bundling belt during vehicle transfer, that is, fix one end of the bundling rope or bundling belt to the vehicle body and wind the other end around the handle assembly, thereby ensuring the reliable fixation of the metering pump relative to the vehicle body and avoiding collisions between the metering pump and the vehicle body.

[0013] Preferably, the position of the bracket relative to the rack along the axial direction of the arc-shaped support surface is adjustable, and / or the position of the fixing part relative to the rack along the axial direction of the arc-shaped support surface is adjustable.

[0014] The position adjustment can be achieved in various ways, including but not limited to slide rail mechanisms, lead screw mechanisms, and waist-shaped hole structures.

[0015] This solution makes the position of the bracket and / or the fixing part adjustable, so as to be able to adapt to metering pumps of different size specifications, making this solution more versatile.

[0016] Preferably, at least two mounting structures are provided on the rack, and the mounting structures are distributed at intervals along the axial direction of the arc-shaped support surface, and the mounting structures are used to mount the bracket or the fixing part.

[0017] This solution is to set mounting structures with different positions on the rack. When the bracket or the fixing part is mounted on different mounting structures, the position of the bracket or the fixing part relative to the rack can be changed, so as to adapt to metering pumps of different size specifications, making this solution more versatile.

[0018] Preferably, at least two groups of connection holes are provided on the fixing part, and each group of connection holes is respectively adapted to the mounting holes of different metering pump bases.

[0019] This solution enables the fixing part to have at least two groups of connection holes with different specifications, so as to be able to fix at least two different specifications of metering pumps, making this solution more versatile.

[0020] Preferably, the bracket is detachably connected to the frame, and / or the fixing part is detachably connected to the frame.

[0021] The specific structural forms of the detachable connection include but are not limited to threaded connection, mortise and tenon connection, and snap connection.

[0022] This solution enables the bracket and / or the fixing part to be detachably connected to the frame, which can facilitate the replacement of the bracket and / or the fixing part when the bracket and / or the fixing part do not match the metering pump, and when the bracket / fixing part is damaged.

[0023] Preferably, the handle assembly includes a cylindrical gripping part, and the diameter of the gripping part is greater than or equal to 20 mm and less than or equal to 30 mm.

[0024] This solution recommends the specific shape and size of the handle assembly, which are convenient for human hands to hold and for tying ropes and / or straps.

[0025] Preferably, at least one axial limiting part is included on the gripping part, and the axial limiting part is used to limit the position of the tying rope and / or the tying strap along the axial direction of the gripping part.

[0026] The specific structural forms of the axial limiting part include but are not limited to stepped shafts, limiting blocks, and snap rings, as long as they can limit the axial movement of the tying rope and / or the tying strap along the gripping part.

[0027] Tying ropes, such as steel wire ropes, nylon ropes, and hemp ropes; tying straps, such as leather belts, nylon belts, and woven belts.

[0028] This solution adds an axial limiting part to the cylindrical gripping part. When using the gripping part to wind and tie the tying rope and / or the tying strap, it can prevent the tying rope and / or the tying strap from slipping axially relative to the gripping part, thereby ensuring the tying and fixing effect.

[0029] Preferably, the handle assembly includes a flexible coating layer.

[0030] The flexible coating layer, such as a rubber layer, a fabric layer, a leather layer and other flexible coating layers; the flexible coating layer can completely cover the outer surface of the handle assembly, or only cover a part of the outer surface of the handle assembly.

[0031] This solution can improve the grip feeling when the operator grasps the handle assembly, thereby reducing the wear of the operator's hands and reducing the chance of the handle assembly slipping from the operator's hands, which may cause the metering pump to fall and personnel to be injured.

[0032] Preferably, the flexible coating layer is detachably connected to the handle assembly.

[0033] The detachable connection methods of the flexible coating layer include but are not limited to pasting, sleeving, and tying.

[0034] This solution can facilitate the replacement of the flexible covering layer when the flexible covering layer is worn.

[0035] Preferably, the rack comprises a frame-type structure.

[0036] This solution can reduce the weight of the rack, thereby reducing the burden on operators and vehicles.

[0037] Compared with the prior art, the beneficial effects of the utility model are:

[0038] The utility model provides a metering pump transport device, which is designed to match the metering pump in appearance. When the metering pump needs to be transported, the mounting hole on the base of the metering pump is aligned with the connecting hole of the fixing part, and the metering pump can be connected to the frame through a threaded connector. The pump head is then supported on the arc-shaped supporting surface of the bracket to prevent the metering pump from tipping over due to unbalanced force. The handle assembly can be used as a fulcrum for operators to exert force during manual transport, thereby making manual transport operations easier and avoiding falling accidents and the resulting personal injuries. On the other hand, it can be used as a fixing point for a tying rope or a tying belt during vehicle transportation, that is, one end of the tying rope or the tying belt is fixed to the vehicle body, and the other end is wrapped around the handle assembly, thereby ensuring that the metering pump is reliably fixed relative to the vehicle body and avoiding collisions between the metering pump and the vehicle body.
