Technical Field

The utility model relates to a beam-pumping unit overhauls the field, concretely relates to beam-pumping unit patrols and examines safety hook who uses.

Background

The oil pumping machine is patrolled and examined by oil extraction staff regularly, the staff checks each point of the oil pumping machine according to specified content and steps, and the normal work of the oil pumping machine is guaranteed by finding and solving the existing problems in time.

In many inspection projects of the pumping unit, the base, the power part, the brake part, various valves at the wellhead and other projects of the pumping unit can be inspected on the ground, but the parts above the reduction gearbox, including a tail shaft, a walking beam, a crank connecting rod and the like, need workers to perform high-altitude operation, and the personal safety of the workers in the maintenance process is hidden.

At present, the platform has been set up on the upper portion of support to partial beam-pumping unit, and the staff stands and operates on it, can hang the couple of safety belt on the guardrail, and this setting can play the effect of guaranteeing safety when the staff carries out operations such as centraxonial inspection, angle sensor's inspection, but can not play the effect when walking beam both sides inspection, for example when examining positions such as horse head, tail shaft and crossbeam, because there is not suitable couple point, the staff has great potential safety hazard when examining these positions.

SUMMERY OF THE UTILITY MODEL

To the technical problem, the utility model provides a safety hook that uses is patrolled and examined to beam-pumping unit through setting up this safety hook in the different positions of walking beam, adapts to the situation that the staff overhauld in the different positions of beam-pumping unit, reaches the purpose of the potential safety hazard that exists when eliminating the staff operation.

The technical scheme is as follows: the utility model provides a safety hook that beam-pumping unit patrolled and examined use which characterized by: the device comprises a triangular positioning plate, wherein a pair of shafts I are arranged at the upper part of the positioning plate, clamping jaws are movably sleeved on the shafts I, and flanges are fixedly arranged at the upper parts of the clamping jaws; a hanging rod is welded below the positioning plate, a fixing block I is welded on the upper portion of the hanging rod, a fixing block II is welded on the lower portion of the hanging rod, a square sliding block is movably sleeved on the hanging rod between the fixing block I and the fixing block II, an ear portion extends out of the side face of the sliding block, and a guide hole is formed in the ear portion; an elastic metal strip is welded below the clamping jaw, the elastic metal strip penetrates through the guide hole, and the lower part of the elastic metal strip is fixedly connected with the fixing block II; a compression spring is sleeved on the hanging rod between the fixed block I and the sliding block, the upper end of the compression spring acts on the lower surface of the fixed block I, and the lower end of the compression spring acts on the upper surface of the sliding block; the lower part of the hanging rod transversely penetrates through a shaft II which is movably connected with a hook.

Further, the fixing block II and the elastic metal strip are fastened through bolts.

Has the advantages that: the utility model discloses a through compression spring's elasticity make the jack catch and rather than fixed connection's flange can the card establish in the lower part of walking beam, and can take off this utility model through overcoming compression spring's elasticity, even make this utility model can set up at the different positions of walking beam according to the on-the-spot needs, and then effectively guarantee the personal safety of staff when carrying out the beam-pumping unit and patrolling and examining the operation.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the accompanying fig. 1 to 2, but the invention can be implemented in many different ways as defined and covered by the claims.

Just as the technical problem that needs to solve at present that the background art recorded, in prior art, the middle part of walking beam 15 has set up the platform, and the staff can hang the safety belt on the guardrail when overhauing at this position, guarantees personal safety, however, when operating in the both sides of walking beam 15, because the I-shaped characteristic of walking beam 15, can't hang the couple of safety belt, and the couple also can't be hung to the great bore of member such as tail-shaft class, consequently there is great potential safety hazard in operating at these positions.

Combine fig. 1 to fig. 2, the utility model provides a safety hook that uses is patrolled and examined to beam-pumping unit, it includes a triangle-shaped's locating plate 13, and there are two angles on the upper portion of this locating plate 13, and there is an angle in the lower part, the upper portion of locating plate 13 sets up a counter shaft I2, jack catch 14 is established to the equal movable sleeve of axle I2 for a pair of jack catch can rotate and mirror symmetry around axle I2, the fixed flange 1 that sets up in upper portion of jack catch 14, the lower part of establishing at walking beam 15 can be grabbed to flange 1.

A peg 4 of below welding of locating plate 13, the upper portion welded fastening piece I3 of peg 4, this fixed block I3 can be circular also can be square, the lower part welded fastening piece II6 of peg 4, this fixed block II6 is preferred to use squarely, because other parts need be connected to fixed block II6, set up to squarely can realize face and face contact fixed block I3 with between the fixed block II6 a square slider 10 is established to the movable sleeve on the peg 4, the side of slider 10 extends ear 5, ear 5 is equipped with guiding hole 16.

An elastic metal strip 12 is welded below the claw 14, the elastic metal strip 12 passes through the guide hole 16, the lower part of the elastic metal strip 12 is fixedly connected with the fixing block II6, namely, when the sliding block 10 moves longitudinally, the lug part 5 of the sliding block can act on the elastic metal sheet 12, so that the elastic metal sheet 12 is deformed, and the claw 14 can rotate around the shaft I2.

The fixed block I3 with between the slider 10 the peg 4 goes up the cover and establishes compression spring 11, compression spring 11's upper end acts on below fixed block I3, compression spring 11's lower extreme acts on the higher authority of slider 10, namely make compression spring 11's elasticity can make slider 10 move down for jack catch 14 grasps walking beam 15, and after the staff manually moved up slider 10 and overcome compression spring 11's elasticity, jack catch 14 can break away from walking beam 15, makes this utility model can set up the different positions at walking beam 15 like this.

Axle II7 is worn to establish along transversely in the lower part of peg, an axle II7 swing joint couple 8, this couple 8 are used for connecting the couple of safety belt, even when making this utility model be in the different positions of walking beam 15, the staff can hang the safety belt and establish on this utility model.

According to the structure of above-mentioned embodiment can discover, this utility model has utilized jack catch 14 and flange 1 to grab the mode of establishing in the lower part of walking beam 15 and has been fixed a position for couple 8, and this action has safe and reliable's characteristics because compression spring 11 acts on slider 10, when the staff need with this utility model setting in the other positions of walking beam 15, only need shift up slider 10 for elastic metal piece 12 warp, and then drive jack catch 14 and rotate around axle I2, make flange 1 break away from walking beam 15 can.

With reference to fig. 1 to 2, in order to facilitate replacement of parts such as the elastic metal sheet 12, the fixing block II6 is fastened to the elastic metal strip 12 by bolts 9.

Finally, it should be noted that the present invention is described in detail with reference to the walking beam 15 as an example, but it can be found that the present invention can be disposed on a cross beam and other parts having a pair of right-angled sides according to the structure disclosed in the present invention.
