Description
Technical Field
The utility model relates to the technical field of oil pumping unit production and manufacturing, in particular to an auxiliary dismounting device for a transmission belt of an oil pumping unit.
Background
Pumping units are the most common surface equipment for oilfield oil recovery equipment. The pumping unit is characterized in that a main motor transmits power and rotating speed to a speed reducer through a belt transmission device, a crank rod is driven to rotate after the speed reducer distributes and decelerates, the crank rod drives a long connecting rod to enable a cross beam to swing up and down, so that a swinging head swings up and down around the center, and a steel wire rope drives a pumping rod to move up and down to perform pumping.
The transmission belt in the belt transmission device is easy to abrade and loosen in the running process, the transmission efficiency can be influenced by excessive use, the oil extraction operation is influenced, and the transmission belt is required to be disassembled and replaced in a specified replacement period. Because most pumping units are used for pumping work in the field, the existing transmission belt disassembly and assembly and replacement modes are also relatively rough, the transmission belt is pried and disassembled by a worker holding a pry bar and a pull rope, tools are not taken by hands when in actual disassembly and replacement operation, the operation is inconvenient to use, time and labor are wasted when in disassembly and replacement operation, the labor intensity is high, and the working efficiency is low.
Disclosure of Invention
The utility model aims to solve the defects in the prior art and provides an auxiliary device for disassembling and assembling a transmission belt of an oil pumping unit, which has the advantages of simple and novel structure, practical function, convenient and quick use, time and labor saving, and is beneficial to reducing the labor intensity and improving the working efficiency.
The technical scheme adopted by the utility model is as follows: the utility model provides a dismouting auxiliary device for beam-pumping unit drive belt, includes housing 1, door plant 2 and pull rod 3, and housing 1 installs in the outside of drive belt, and door plant 2 is connected with housing 1 is articulated through hinge 4, is fixed with installation piece 5 on the medial surface of door plant 2, and the upper end of pull rod 3 is connected with installation piece 5 is articulated through the round pin axle, and the lower extreme of pull rod 3 is equipped with the couple.
The further improvement is that the inner side surface of the door plate 2 is fixedly provided with a hinged supporting block 6, the hinged supporting block 6 is hinged with a supporting rod 7 in a sliding way through a pin shaft, the housing 1 is fixedly provided with a fixed supporting block 8, the supporting rod 7 is uniformly provided with grooves in parallel, the fixed supporting block 8 is provided with convex teeth, and the convex teeth are inserted into the grooves.
A further improvement consists in that the inner side of the door panel 2 is provided with an elastic buckle or a magnet for fixing the pull rod 3.
Compared with the prior art, the utility model has the following beneficial effects: simple structure is novel, and the function is practical, and convenient to use is swift labour saving and time saving, is favorable to reducing intensity of labour, improves work efficiency.

Detailed Description
The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.
As shown in fig. 1, an auxiliary device for disassembling and assembling a transmission belt of an oil pumping unit comprises a housing 1, a door plate 2 and a pull rod 3, wherein the housing 1 is covered outside the transmission belt, the door plate 2 is hinged with the housing 1 through a hinge 4, a mounting block 5 is fixed on the inner side surface of the door plate 2, the upper end of the pull rod 3 is hinged with the mounting block 5 through a pin shaft, a hook is arranged at the lower end of the pull rod 3 and is hooked on the transmission belt, the door plate 2 is opened to overturn upwards around the hinge 4, the hinge 4 is used as a fulcrum, and the pull rod 3 pulls the transmission belt to be disassembled and assembled upwards and outwards.
The inner side surface of the door plate 2 is fixedly provided with a hinged supporting block 6, the hinged supporting block 6 is hinged with a supporting rod 7 in a sliding manner through a pin shaft, the housing 1 is fixedly provided with a fixed supporting block 8, the supporting rod 7 is uniformly provided with grooves in parallel, the fixed supporting block 8 is provided with convex teeth, and the convex teeth are inserted into the grooves. When the pull rod 3 pulls the transmission belt to be disassembled and assembled outwards, the supporting rod 7 is pulled to move on the fixed supporting block 8, and when the door plate 2 stops to be overturned upwards, the convex teeth are inserted into the grooves to clamp the overturned position of the door plate 2, so that the transmission belt is convenient to disassemble and assemble.
As shown in fig. 2 and 3, an elastic buckle or a magnet is provided on the inner side of the door panel 2 for fixing the pull rod 3. When the door plate 2 needs to be closed, the lower end of the pull rod 3 is clamped with the elastic buckle or is attracted with the magnet, so that the pull rod 3 is fixed, the support rod 7 slides on the pin shaft, the support rod 7 is separated from the fixed support block 8, and the door plate 2 rotates downwards to be closed.
Without being limited thereto, any changes or substitutions that are not contemplated by the inventors are intended to be included within the scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
