Abstract
The utility model discloses a load sensor wiring device for measuring an indicator diagram of an oil-pumping unit. The load sensor wiring device solves the problem that the present load sensor frequently has water inflow, corrosion and rustiness under the adverse environment and can be damaged for different degrees in use, has the advantages of high durability, waterproof performance and convenient assembly and disassembly, and is not easy to damage in use. The load sensor wiring device for measuring an indicator diagram of an oil-pumping unit is provided with a load sensor. The utility model is characterized in that the load sensor is provided with a wire rope fixing bracket, a wire rope is fixed on the wire rope fixing bracket, one end of the wire rope is welded with a flexible cord to form a waterproof joint, and the other end of the flexible cord forms non-polar connection with a wiring column in a sealed waterproof wiring device.
Description
Technical field
The utility model relates to a kind of termination, relates in particular to the load sensor termination in a kind of oilfield remote measurement and control.
Background technology
Load-position diagram was measured the load sensor that uses in the oilfield remote measuring and controlling system in the past, usually adopt the connector mode, what have is the aviation connector, what have is waterproof plug, and the former often intakes under this rugged surroundings in oil field, burn into rust tongued bell, and dual mode all needs connector under the button when operation, and in fact all broken by the operating personnel, web member damages, and causes every operation once, and load sensor all can damage to some extent.
Summary of the invention
The utility model is exactly in order to address the above problem, and a kind of very easy load cell termination that do not damage when waterproof, operation are provided and install is provided.
For achieving the above object, the utility model has adopted following technical scheme: a kind of pumping-unit workdone graphic is measured and is used the load sensor termination, it has load sensor, it is characterized in that: the wirerope fixed support is arranged on load sensor, be fixed with wirerope on it, wirerope one end welding flexible cord forms water joint, the nonpolarity connection of binding post in the flexible cord other end and the water-tight termination.
Described water-tight termination comprises, is installed in the transmitter box on the load sensor, and the wiring board fixed cap is installed on the transmitter box, covers the installation wiring board at this; Between wiring board fixed cap and installation wiring board is waterproof pad; Seal weld in the circuit board is connected to binding post, and there are polarity switching circuit and inner connector in the wiring board back side.
Described binding post has gold-plated coating, and it is made up of the nut double-screw bolt; Apply copper on the wiring board, the nut double-screw bolt is by the weld zone seal welding of scolding tin on deposited copper; The bridge rectifier circuit that described polarity switching circuit is constituted by a diode.
Described load sensor is the bracelet shape, is sleeved on the oil-extractor polish-rod; At least two cables are arranged in the wirerope, and its end is welded on the oil pumper derrick, and the other end is crossed steel with the steel cartoon and fastened screw and be fixed on the wirerope fixed support.
Adopt wirerope (steel wire bag cable) connected load sensor and equipment in the technical solutions of the utility model, make it firm; Insert one section soft cable between wirerope and load sensor, workmen's hard draw broken string can not damage load sensor when guaranteeing operation; Adopt technology such as gold-plated binding post, seal welding and rubber cushion, carry out water-proofing treatment; Add polarity switching circuit at data-interface, make two binding posts nonpolarity, install and when recovering two binding posts each connect single line and get final product, have the durability, the water proofing property that have strengthened whole device, in use be difficult for being damaged, the advantage of easy accessibility.

Embodiment
Load sensor 2 among Fig. 1, it is the bracelet shape, be enclosed within on the polished rod of oil pumper 1,8 one on wirerope is weldingly fixed on the oil pumper derrick with the steel card, crossing steel with the steel cartoon for one fastens screw 9 and is fixed on the wirerope fixed support 10, (two) strip out with wirerope 8 inner cables, weld with flexible cord 12 and they, and wirerope and flexible cord joint 11 are carried out water-proofing treatment.Gold-plated binding post 6 is welded on the wiring board 7, and the back side is welded with the polarity switching circuit (see figure 3), and flexible cord 12 is connected (two lines connect arbitrarily) with gold-plated binding post 6, promptly finishes the wiring of load sensor.Transmitter box 3 is arranged on load sensor 2, and wiring board fixed cap 4 is installed on this transmitter box 3.
During design, the flexible cord of use can rupture from gold-plated binding post when haling, but does not damage binding post, during recovery as long as handle flexible cord 12 joints again and be pressed on the gold-plated binding post 6.
Among Fig. 2, during actual design, have only two holes that gold-plated binding post 6 is installed on the wiring board 7, all the other all are the welding of single face paster, also have interconnect 15 on wiring board 7, are used to connect circuit.Two gold-plated binding post 6 mounting holes weld the pad on gold-plated nut, double-screw bolt 14 and the deposited copper circuit board in the lump with scolding tin after screw is fixing, and with weld zone 13 sealings.Between the wiring board 7 of load sensor connection jaws and the wiring board fixed cap 4 waterproof pad 5 is arranged, the gold-plated binding post 6 on the wiring board 7 is a seal welding, has guaranteed waterproof.
Fig. 3 is the polarity automatic switch-over circuit, because the standard that load sensor is is output as the current signal of 4-20mA, circuit does not have influence to its precision.Nonpolarity circuit guarantees that any workmen can both reconnection.
