Abstract
The utility model belongs to the field of machine manufacturing, relates to a communication antenna lifting system, and discloses a sleeve type antenna lifting oil cylinder. A plunger is arranged in sleeves of the lifting oil cylinder, the top end of the sleeve of each stage is provided with a shaft sealing ring, a shaft guide ring and a dust ring, and the lower end of the sleeve of each stage is provided with a hole guide ring and a hole limiting key. A balance weight connection plate is arranged at the top end of the plunger, fastened by a locking nut and provided with an antenna lifting plate. A clamping key is arranged on the cylinder bottom. An outer cylinder barrel is provided with an oil inlet and check valve assembly and an oil outlet and check valve assembly. According to the sleeve type antenna lifting oil cylinder, the telescopic sleeve oil cylinder structure is adopted, so that the shortcoming that a traditional oil wire rope structure consumes time and labor is overcome, the operation time is shortened, and the service life is prolonged. Through the oil inlet and check valve assembly and the oil outlet and check valve assembly, the oil cylinder is safer and more reliable in the working process. Through a manually-screwed screw and a big-bore fast oil outlet connector on an oil outlet, oil can be fast drained and the oil cylinder can be fast withdrawn under the condition that the task is completed or emergencies occur. The stroke of the oil cylinder is 16700 mm and can be high above the ground by more than 20 m when connected with the outer cylinder barrel.
Description
Technical field
The utility model belongs to mechanical manufacturing field, relates to a kind of communication antenna hoisting system.
Background technique
The antenna lifting equipment of existing market is mainly oil thread rope, has lower column defects on this product structure: 1, manual operation heaviness, painstaking.2, there is structural defect in oil thread rope, and rate of fault is high, the life-span is short.3, can not realize quick lifting and decline; Inconvenient, dumb.4, be not suitable for being applied to 20 meters of high-altitude lifting antennas and reset, require great effort large, dangerous.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of novel background technique Telescopic oil tank, heavy, painstaking to solve prior art operation; Can not realize the quick lifting of portable antenna, decline; The defects such as rate of fault is high, the life-span is short.
The technological scheme that the invention for solving the technical problem adopts is: plunger is set in sleeve, plunger is solid construction, more easily fall after rise by deadweight, sleeves at different levels top arranges seal ring for axle, axle guide ring and dust ring, sleeve lower end arranges hole guide ring and hole positive stop key, structural design guidance quality is good, and intensity is high; Plunger top arranges counterweight land, adopts locking nut fastening, on counterweight land, antenna is set and lifts dish; Bottom at cylinder bottom arranges card key; Outer cylinder arranges into and out of hydraulic fluid port band one-way valve assembly, makes high-lift operation safety and reliability.
Axle adopts tin bronze material with guide ring and hole guide ring.
Adopt good effect of the present utility model to be 1, to adopt Telescopic oil tank structure, avoided the defect that wastes time and energy of traditional silk noil rope structure, save the operating time, improved the life-span.2, make oil cylinder more safe and reliable in the course of the work by oil inlet and outlet band one-way valve structures design, screw rod and the large quick oil outlet fitting of latus rectum are manually tightened by oil outlet place, can finish the work or emergency situations under the withdrawal oil cylinder of draining the oil fast.3, sleeve adopts E355 essence tube drawing, hole with and axle guide ring all adopt the blue or green material of tin, make large stroke oil cylinder guidance quality better, long service life, failure rate is low.4, oil cylinder stroke 16700mm, connects outer cylinder road clearance and can reach more than 20 meters.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Accompanying drawing 1 is the utility model structural representation:
In figure 1 card key, 2 hexagon head bolts, 3 cylinder bottoms, 4 for hole positive stop key, 5 for axle positive stop key, 6 outer cylinders, 7 for hole guide ring, 8 sleeves, 9 filler opening band one-way valve assemblies, 10 plungers, 11 oil outlet band one-way valve assemblies, 12 seal rings for axle, 13 guide rings for axle, 14 dust rings, 15 counterweight lands, 16 locking nuts, 17, antenna lift dish.
Embodiment
As shown in the figure: the interior plunger 10 that arranges of sleeve 8, plunger 10 is solid construction, more easily falls after rise by deadweight, sleeves at different levels 8 tops arrange seal ring 12 for axle, axle guide ring 13 and dust ring 14, sleeve 8 lower ends arrange hole guide ring 7 and positive stop key 4 for hole, and structural design guidance quality is good, and intensity is high; Plunger 10 tops arrange counterweight land 15, adopt locking nut 16 fastening, antenna is set on counterweight land 15 and lifts dish 17; In the bottom of cylinder bottom 3, card key 1 is set; Outer cylinder arranges into and out of hydraulic fluid port band one-way valve assembly 9,11, makes high-lift operation safety and reliability.Outer cylinder is recognized and is put 8 holes and be connected with corresponding connecting plate, and hinge two ends are connected with vehicle seat support, and outer cylinder top arranges gusset plate, used in order to reinforcing.
Axle adopts tin bronze material with guide ring 13 and hole guide ring 7.
