The utility model has the advantages of simple structure, convenient operation and high safety and can avoid the damage on the pulley.

Description

The motor pulley assembler

Technical field

The utility model relates to the motor pulley assembly tool, particularly is a kind of motor pulley assembler.

Background technology

At present, in field produces, the adjustment of oil pumper jig frequency is regular work, change motor pulley and can change the oil pumper jig frequency, usually the mode of knocking with copper rod on the big pallet is installed belt pulley, on-the-spot because no copper rod often directly knocks belt pulley, such operation exists following problem: the one, easily cause danger; The 2nd, knock with sledgehammer pulley rim, motor shaft are easily caused damage; The 3rd, breaking axis does not just easily take place in the belt pulley of installing.Thereby prior art can not address the above problem.

The utility model content

The utility model designs a kind of motor pulley assembler at above-mentioned technical problem exactly, solves the problem that exists in the assembling of pumping-unit motor belt pulley.

The technical scheme that the utility model will be dealt with problems is a kind of motor pulley assembler, comprising: column, hook bolt, single-acting jack, very heavy bearing, nut, center silk braid, jackscrew, crossbeam, iron chains, take over a business, right angle bolt, high-pressure hose, handlance; It is the "T"-shaped supporting structure that rectangle hollow steel member column and crossbeam are welded for section, have the hook bolt groove in column the first half, hook bolt is installed in the hook bolt groove also can be gone up, move down, hang iron chains on the hook of hook bolt, the latter half has the central hair grooving, the center silk braid is mounted in the central hair grooving by nut thread, and can go up, move down, the jackscrew that has trapezoidal thread is contained in the silk braid of center, silk braid rear end, center is threaded with the very heavy bearing that has opening, the single-acting jack is placed in the very heavy bearing, the single-acting jack is connected with handlance by high-pressure hose, respectively have a right angle bolt slot on the crossbeam both sides, two right angle bolts are installed in respectively in the right angle bolt slot, and can be left, move right.

Center silk braid in the above-mentioned motor pulley assembler is a cylindrical tube, left end is provided with external screw thread, and right-hand member is for having externally threaded boss, and the boss left side is a symmetry circumference structure, the center is provided with the trapezoidal internal thread through hole, and right-hand member is the annular boss greater than the trapezoidal internal thread through-hole diameter.

In the above-mentioned motor pulley assembler very heavy bearing be the cylindrical tube body structure, left end is for being a boss, boss is provided with an opening from the right side, there is a through hole at the center, left end is for greater than the annular boss that has internal thread of central through hole diameter.

Motor pulley assembler according to the such scheme manufacturing, simple in structure, easy to operate, safe and reliable, avoid belt pulley, motor shaft to damage, reducing motor burns out, prolong belt service life, avoid because of changing the production loss that the well of lying that motor causes causes, rate during the raising oil well production, increase crude output, have remarkable economic efficiency.

The specific embodiment

The utility model comprises: column 1, hook bolt 3, single-acting jack 4, very heavy bearing 5, nut 7, center silk braid 8, jackscrew 9, crossbeam 12, iron chains 13, take over a business 19, right angle bolt 21, high-pressure hose 22, handlance 23; It is the "T"-shaped supporting structure that rectangle hollow steel member column 1 and crossbeam 12 are welded for section, have hook bolt groove 2 in column 1 the first half, hook bolt 3 is installed in the hook bolt groove 2 also can be gone up, move down, hang iron chains 13 on the hook of hook bolt 3, the latter half has central hair grooving 6, center silk braid 8 is threaded by nut 7 and is installed in the central hair grooving 6, and can go up, move down, the jackscrew 9 that has trapezoidal thread is contained in the center silk braid 8, silk braid 8 rear ends in center are threaded with the very heavy bearing 5 that has opening, single-acting jack 4 is placed in the very heavy bearing 5, single-acting jack 4 is connected with handlance 23 by high-pressure hose 22, respectively have 11, two right angle bolts 21 of a right angle bolt slot on crossbeam 12 both sides and be installed in respectively in the right angle bolt slot 11, and can be left, move right.

Use method of operating: at first, the gib head of two right angle bolt slots 11 is inserted in the fixing hole 18 of motor 14, iron chains 13 is tied the fan end of motor 14; Secondly, make the centre bore, keyway of belt pulley 16 relative with key on the motor shaft 15; The 3rd, single-acting jack 4 and belt pulley 16 are aligned, regulate the nut of hook bolt 3, tension iron chains 13 is regulated right angle bolt 21 simultaneously, with fixing hole 18 tensions of motor 14, the upper and lower handle that lifts handlance 23, then single-acting jack 4 is contained in belt pulley 16 on the motor shaft 15.

If single-acting jack 4 damages, then single-acting jack 4 is taken off, lay down very heavy bearing 5, with the crowbar through hole 10 of crowbar insertion jackscrew 9, positive hour hands pivot jackscrew 9, then center jackscrew 9 is contained in belt pulley 16 on the motor shaft 15.
