Technical Field

[0001] The utility model relates to the technical field of oil well pumps, in particular to a supporting tooling for an oil well pump barrel. Background Art

[0002] At present, when polishing and removing burrs on the outer wall of the pump barrel and coating anti-corrosion materials, a pair of clamps are used to support the pump barrel. Since the clamps are fixed on the outer wall of the pump barrel, part of the outer wall of the pump barrel is blocked, which makes it impossible to polish and paint this part. It is necessary to wait until other positions are processed before performing a secondary operation on this part, which increases the operation cycle. Therefore, the inventor wants to design a special pump barrel support tooling for polishing and painting operations. Summary of the invention

[0003] The purpose of the utility model is to address the defects of the prior art and to provide a supporting tool for the pump barrel of an oil pump, which can support and fix pump barrels of different sizes, is more flexible and convenient to use, and after support, the outer wall of the pump barrel is not blocked, and does not affect polishing and painting operations.

[0004] The technical solution of the utility model is: a supporting tool for a pump barrel of an oil well pump, comprising a pair of symmetrically arranged supporting components;

[0005] The support assembly comprises a base, an upper end surface of the base is vertically connected to a vertical plate, a horizontally arranged lead screw is threadedly connected to the vertical plate, one end of the lead screw is connected to a hand wheel, and the other end is rotatably connected to a support block, and both sides of the support block are symmetrically provided with inclined support surfaces;

[0006] A pair of L-shaped brackets are symmetrically arranged on both sides of the support block, the lateral ends of the L-shaped brackets are provided with inclined surfaces that slide with the support surfaces of the support block, and the longitudinal ends of the L-shaped brackets are slidably sleeved with sliding sleeves, which are fixedly connected to the vertical plates.

[0007] Preferably, the outer side surface of the lateral end of the L-shaped bracket is a curved surface structure adapted to the inner wall of the pump barrel.

[0008] Preferably, a group of reinforcing ribs are provided between the base and the vertical plate.

[0009] Preferably, the outer side of the hand wheel is connected with a rocker arm

[0010] Compared with the prior art, the utility model has the following advantages: the utility model drives the support block to move by rotating the hand wheel, and pushes the L-shaped brackets on both sides to move outward through the inclined support surfaces on both sides of the support block, thereby increasing the distance between the two L-shaped brackets, and then fixing the pump barrel support on the two L-shaped brackets.

[0011] The utility model has a simple structure and low manufacturing cost, can support and fix pump barrels of different sizes, is more flexible and convenient to use, and after the support, the outer wall of the pump barrel is not blocked, and polishing and painting operations are not affected.

[0016] The utility model is further described below with reference to the accompanying drawings and embodiments. Example 1

[0017] like Figures 1 to 3 A support fixture for a pump barrel of an oil well pump comprises a pair of symmetrically arranged support assemblies 13.

[0018] The support assembly 13 comprises a base 4, an upper end surface of which is vertically connected to a vertical plate 1, and a horizontally arranged lead screw 8 is threadedly connected to the vertical plate 1.

[0019] One end of the screw 8 is fixedly connected to the handwheel 2, and the other end of the screw 8 is rotatably connected to the support block 9. The two sides of the support block 9 are symmetrically provided with inclined support surfaces. The support block 9 is an isosceles trapezoidal structure as a whole, and the screw 8 is rotatably connected to the bottom position of the isosceles trapezoidal structure.

[0020] A pair of L-shaped brackets 7 are symmetrically arranged on both sides of the support block 9. The L-shaped brackets are arranged horizontally. The L-shaped brackets 7 are divided into two parts: a transverse end 11 and a longitudinal end 10.

[0021] The transverse end 11 is provided with an inclined surface that is slidably matched with the support surface of the support block 9 , and the longitudinal end 10 is externally slidably sleeved with a sliding sleeve 6 , which is fixedly connected to the vertical plate 1 .

[0022] Working principle:

[0023] When in use, the pump barrel 14 is sleeved on the outside of the lateral ends 11 of the two L-shaped brackets 7, and then the hand wheel 2 is turned to drive the support block 9 to move, and the L-shaped brackets 7 on both sides are pushed outward through the inclined supporting surfaces on both sides of the support block 9, thereby increasing the distance between the two L-shaped brackets 7, and then the pump barrel 14 is supported and fixed on the lateral ends 11 of the two L-shaped brackets 7. The state after support and fixation is shown in Figure 3, and the pump barrel 14 can be released by rotating the hand wheel 2 in the opposite direction.

[0024] The utility model has a simple structure and low manufacturing cost, can support and fix pump barrels 14 of different sizes, is more flexible and convenient to use, and after support, the outer wall of the pump barrel 14 is not blocked, does not affect polishing and painting operations, and improves operating efficiency. Example 2

[0025] This embodiment is further optimized on the basis of the above embodiment, specifically:

[0026] like Figure 1 and Figure 2 The outer side surface of the lateral end 11 of the L-shaped bracket 7 is a curved surface structure 12 adapted to the inner wall of the pump barrel 14. The curved surface structure 12 increases the fitting area with the inner wall of the pump barrel 14, and the support and fixation are more firm.

[0027] like Figure 1 A set of reinforcing ribs 5 are provided between the base 4 and the vertical plate 1 to improve the overall structural stability.

[0028] like Figure 1 and Figure 3 The outer side of the hand wheel 2 is connected with a rocker arm 3. Adding the rocker arm 3 makes it easier to shake the hand wheel 2 to drive the lead screw 8 to rotate.

[0029] The present invention is not limited to the above-mentioned implementation modes. Within the knowledge scope of those skilled in the art, various changes can be made without departing from the purpose of the present invention. The changed contents still belong to the protection scope of the present invention.
