The unlocking pin pull rod with the structure not only improves the convenience of the unlocking process, but also saves the manpower.
Description
Technical Field
The utility model relates to a switch technical field, concretely relates to retractable release pin pull rod.
Background
The turnout is a basic arrangement that one track is branched into two or more tracks, so that a track traffic train is transferred from one track to the other track, the turnout switching or conversion can be realized by driving the train to move from one track to the other track, and the magnetic suspension turnout switching is realized by driving a turnout pile beam to move by a switching motor under the normal condition; manually shaking a switch motor rotor to move a turnout pile beam when a switch motor fails, locking the turnout after the turnout is switched in place to ensure driving safety, and normally driving a locking device through a locking motor to realize turnout locking; when the locking motor fails, the rotor of the locking motor is manually rotated to drive the locking device to be locked, and under the condition of the failure of the locking motor, a switch device which allows or does not allow manual operation is arranged for preventing misoperation, and an unlocking pin on the band-type brake mechanism needs to be pulled and always kept at an allowed position before manual operation.
At present, when the locking motor is unlocked, one person needs to continuously pull the unlocking pin to keep an allowable state, so that manpower is not saved, and the unlocking pin is usually located at a position with a relatively high position, so that the unlocking process is inconvenient to operate.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing a retractable release pin pull rod to improve the convenience of unblock process, practice thrift the manpower simultaneously.
The utility model discloses an above-mentioned problem is solved to following technical means: a telescopic unlocking pin pull rod comprises a pull ring, a front rod and a rear barrel, wherein jacks are symmetrically formed in two sides of the head end of the front rod, the ends of the two ends of the pull ring are respectively matched and spliced with the jacks on the corresponding side, a plurality of grooves are uniformly formed in the circumferential direction of the inner wall of the jack on at least one side, and protrusions matched with the grooves are arranged on the ends matched with the jacks; the tail end of the front rod is inserted into the rear barrel and is in threaded connection with the rear barrel.
Furthermore, the pull ring is formed by bending an elastic iron wire.
Furthermore, the pull ring is in an inverted U shape.
Further, a tail seat is arranged at the tail end of the rear cylinder.
Further, a hook is arranged on the tailstock.
The utility model has the advantages that: the telescopic unlocking pin pull rod comprises a pull ring, a front rod and a rear barrel, wherein jacks are symmetrically formed in two sides of the head end of the front rod, the ends of the two ends of the pull ring are respectively matched and spliced with the jacks on the corresponding side, a plurality of grooves are uniformly formed in the circumferential direction of the inner wall of the jack on at least one side, and protrusions matched with the grooves are arranged on the ends matched with the jacks; the tail end of the front rod is inserted into the rear barrel and is in threaded connection with the rear barrel. The unlocking pin pull rod with the structure not only improves the convenience of the unlocking process, but also saves the manpower.
Drawings
The invention is further described with reference to the following figures and examples.
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is an enlarged side view of the jack;
fig. 3 is a sectional view of the tip being plugged into the receptacle.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1-3, the retractable unlocking pin pull rod of the present embodiment includes a pull ring 1, a front rod 2 and a rear barrel 3, wherein the pull ring is formed by bending an elastic iron wire, the pull ring is in an inverted "U" shape, two sides of a head end of the front rod are symmetrically provided with insertion holes 201, end heads 101 at two ends of the pull ring are respectively in matching insertion with the insertion holes at corresponding sides, a plurality of grooves 202 are uniformly formed in the circumferential direction of an inner wall of the insertion hole at least one side, and a protrusion 5 matching with the grooves is arranged on the end head matching with the insertion hole; the tail end of the front rod is inserted into the rear barrel and is in threaded connection with the rear barrel. When the unlocking pin pull rod with the structure is used, the unlocking pin is sleeved by the pull ring, a worker holds the rear barrel with one hand, pulls the unlocking pin to be kept at an allowed position, so that unlocking operation can be completed, the other hand of the worker can be used for rocking and locking the motor rotor, the whole locking process can be completed by one person, one person does not need to continuously pull the unlocking pin to keep the allowed state, manpower is saved, the front rod and the rear barrel rotate relatively, the whole length of the pull rod can be adjusted, the pulling requirement of the unlocking pin with different heights can be met, the universality is improved, furthermore, in the process of installing the pull ring, the protrusions are clamped with different grooves, the pull ring can be in different swing angle states, namely different included angle states are maintained between the pull ring and the front rod, so that the pull ring can more conveniently sleeve the locking pins with different angles, the convenience of the use process is greatly improved.
As a further improvement to the above technical solution, the tail end of the rear cylinder is provided with a tailstock 4, and after the drawing process is completed, the tailstock can be fixed by a corresponding fixing structure, so that the pull rod can be kept in a drawing state, and thus a hand for drawing can be vacated.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
