Description

Multifunctional detacher

Technical field:

The utility model relates to a manual dismantling tool, in particular to a dismantling tool used for dismantling various types of pins.

Background technique:

With the continuous development of the power system, the number of substations is constantly increasing, and the workload of repairing and replacing equipment such as isolating switches and circuit breakers in the substations is also increasing. Cotter pins, cylindrical pins, expansion pins, conical pins and other pins have been widely used in power equipment as commonly used tools. Due to the influence of environment, location and other factors, many pins are corroded or their positions are difficult to reach, so that the pins are difficult to disassemble or require a lot of manpower and time to disassemble. According to statistics, sometimes it takes 1.5 to 2 hours to remove a corroded or poorly positioned pin, which not only reduces work efficiency, prolongs the power outage time of the equipment, affects economic benefits, but also reduces the reliability and safety of power supply . The Chinese patent with the publication number CN2734428Y discloses a "quick release pin puller", which is composed of a pull rod, a punch hammer, a nut sleeve and a screw. The pin is disassembled, and the operation is convenient and the work efficiency is high, but the application range is very limited.

Utility model content:

The technical problem to be solved by the utility model is to provide a multifunctional pin remover for the above deficiencies. The pin remover inserts the dismounting head into the tail of a normal or poorly positioned pin according to the characteristics of the pin itself. , Using the inertia generated by the impact to quickly pull out or rush out the pin, the work efficiency is high, the disassembly speed is fast, and the application range is wide.

The technical scheme that the utility model takes is:

A multifunctional pin remover includes a handle, a pull rod and a pulling head, wherein a sliding handle and at least one connecting rod are sequentially arranged between the pull rod and the pulling head.

The threaded connection between the pulling head and the connecting rod is convenient for disassembly and replacement.

Pulling heads include hook lifting heads and straight pulling heads, which are selected according to the pin type.

The handle is threadedly connected with the pull rod.

There is a connecting piece between the pull rod and the connecting rod, and the connecting piece is threadedly connected with the connecting rod and the pull rod.

The sliding handle is sleeved on the pull rod.

The disassembly head of the utility model can be designed in different models according to the different sizes of the pins, thereby greatly shortening the problem of quick disassembly of the pins in normal or poor positions. Fast, high work efficiency, wide range of applications.

Description of drawings:

Fig. 1 is a structural schematic diagram of a hook body from which the pulling head is drawn.

Fig. 2 is a schematic diagram of the structure in which the pulling head is a straight body.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figures 1 and 2, the multifunctional pin remover includes a handle 1, a pull rod 2 and a pulling head 6, and a sliding handle 3 and a connecting piece 4 are arranged between the pull rod 2 and the pulling head 6 in sequence. The threaded connecting rod 5, the threaded connection between the pulling head 6 and the connecting rod 5, the handle 1 and the pull rod 2 are threaded, the pulling head 6 includes a hook lifting head 61 and a straight lifting head 62, the pulling head 6. According to the size and model of the pin, a series of pulling heads can be processed; when in use, firstly select different pulling heads according to the type, position, model, etc. of the pin. Insert the hook head 61 into the gap at the tail of the cotter pin, and then slide the sliding handle 3 forcefully to make it reciprocate on the pull rod 2. When the sliding handle 3 moves to the handle 1, due to being blocked, the sliding The impact force of the handle 3 acts on the handle 1, and this impact force acts on the cotter pin through the handle 1, the pull rod 2, and the pulling head 6, forming an upward pulling force on the cotter pin, thereby quickly disassembling the cotter pin. For cylindrical pins, expansion pins, conical pins, etc., use a straight lifting head 62, put the straight lifting head 62 against the tail of the pin, and then slide the sliding handle 3 downward to make it go back and forth on the pull rod 2 Movement, when the sliding handle 3 moves to the connecting piece 4, due to being blocked, the impact force of the sliding handle 3 acts on the connecting piece 4, and this impact force acts on the connecting piece 4, the connecting rod 5, and the pulling head 6. On the pin, a downward force is formed on the pin to quickly disassemble the pin.
