[0002] After the radial bearing is removed during the overhaul of the main oil pump, the pump shaft is supported only by the mouth ring. Due to the weight of the main body, radial displacement is very likely to occur.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an oil pump shaft lifting tool, comprising: a crossbeam, a bracket, a screw, an electronic measuring mechanism, and a mechanical measuring mechanism. One end of the screw passes through the crossbeam and is rotatably connected to the bracket through the mechanical measuring mechanism. The electronic measuring mechanism is respectively connected to the bracket and the crossbeam, and a pair of waist holes are provided on the crossbeam.

Reduce the data error caused by human factors. Ensure the accuracy of the numerical value. The waist hole design structure can meet the needs of different models of oil pump main pumps and the positioning requirements of multiple types of oil pump bearing boxes. The structure is simple and easy to operate.

[0007] Furthermore, the crossbeam is a T-shaped crossbeam.

Due to its own light weight, it exerts good pressure on the connected equipment components and meets the explosion-proof requirements.

[0011] Furthermore, the mechanical measuring mechanism is evenly provided with circumferential scales.

[0012] The beneficial effect of adopting the above further technical solution is that the mechanical display adopts a circular scale evenly distributed, which is easy to read and improves the stability and reliability of the tool.

[0013] Furthermore, a hand wheel is provided at the other end of the screw.

[0014] The beneficial effect of adopting the above further technical solution is that the screwing method fully considers ergonomics, making it convenient for the user to rotate the screw by means of a hand wheel.

[0015] Furthermore, a rocker is provided on the hand wheel.

[0016] The beneficial effect of adopting the above further technical solution is that the hand wheel and the rocker can realize two modes of coarse adjustment and fine adjustment, and achieve a combination of fast and slow.

[0017] Furthermore, the electronic measuring mechanism comprises: a capacitive barrier sensor and an electronic display component, wherein two ends of the capacitive barrier sensor are connected to the bracket and the crossbeam in a one-to-one correspondence, and the electronic display component is connected to the capacitive barrier sensor.

[0019] Furthermore, the electronic display component is connected to the capacitive sensor via a USB T-type interface.

[0020] The beneficial effects of adopting the above further technical solution are: facilitating the detachable connection between the electronic display component and the capacitive sensor, and facilitating the installation and maintenance of the tool.

[0021] Furthermore, the bracket is made of aluminum alloy, and the crossbeam and screw are made of 45# steel.

[0022] The beneficial effects of adopting the above further technical solution are: reducing the weight of the tool and reducing the cost.

[0023] Furthermore, a thread is provided on the outer side of the screw rod, and the screw rod is transmission-connected to the crossbeam via the thread.

The waist hole design structure can meet the needs of different models of oil main pumps.

[0051] The oil pump shaft lifting tool provided in the embodiment of the present invention is divided into three parts, namely, a supporting part, a screwing part and a measuring part.

[0056] 5) The fixing method adopts the top screw design.

[0057] 6) The transmission structure adopts screw and thread connection.

[0058] Functions and effects:

[0059] 1) The aluminum alloy saddle bracket (bracket) satisfies the requirement of forming a relatively stable supporting mechanism. When directly supporting, it can prevent the tool from deforming or damaging parts. Due to its small weight, it can exert good pressure on the connected equipment components and meet the explosion-proof requirements.

[0066] 8) The whole tool is easy to hold, simple to operate, the data is easy to read, and there is a mechanical bit value comparison.

[0067] The whole set of tools utilizes the equipment body, saving the time of installing the hanger and dial indicator, reducing the labor intensity of the user, and avoiding the risk of damaging the spindle. The number of operators is reduced from 3-4 to 1. The two reading methods of values ​​minimize the impact of system errors.

[0068] This tool avoids the safety risks of traditional methods, reduces the workload of lifting shafts, and significantly improves the overall automation level.
