Description

A kind of combined electric hydraulic lifting limit for height door frame

Technical field

This utility model relates to road and bridge limit for height facility, particularly relates to a kind of combination type automatic hydraulic lifting limit for height door frame.

Background technology

At present, the gate-type limit for height structure (i.e. limit for height door frame) arranged to protect bridge on road, culvert, tunnel, It is generally divided into fixed and lifting type two kinds.Some section should limit bulk production vehicle pass-through, ensures bus again, clears the snow The vehicles such as car, obstacles removing car, dumper, ambulance and fire fighting truck pass through, and this fixed limit for height door frame cannot reach Requirement.Also have a kind of Debacle possible type door frame, can automatically turn on when door frame is clashed into, it is impossible to effectively intercept truck, superelevation overload Vehicle high-speed passes through.Applying more lifting type door frame in the market is electric lifting door frame, by motor with determine cunning Wheel is arranged on liftable crossbeam top, and liftable crossbeam moves up and down under the drive of motor and steel wire rope.Liftable crossbeam Being fixed at the height of needs with steel wire rope, safety is relatively low, and lifting runs unstable, the long-term wind and weather of motor, fault Rate is higher, and motor is arranged at liftable crossbeam, maintenance difficult, and the most electronic liftable limit for height door frame is also difficult in the face of multiple Miscellaneous traffic control demand.

Summary of the invention

This utility model provides a kind of simple in construction, safe and reliable and reusable combined electric fluid pressure type limit High door frame, it is adaptable to town road, plant area of enterprise, park, Huan Hu, along the river, the forbidden section of lorry such as backroad.This practicality is new The implementation of type is as follows: a kind of combined electric hydraulic lifting limit for height door frame, including two groups of columns, liftable crossbeam, limit for height Nameplate, flashing light, wireless bridge shooting video record instrument, bluetooth read head, motor, hydraulic system, can pass through electronic, hands Dynamic, bluetooth, remote control, electronics various ways of swiping the card opens and closes.Door frame uses bidirectional hydraulic jacking system, and keying is fast, noise is little, Can position by desired height, pin is fixed, is not affected by high and cold harsh weather, sturdy and durable strong adaptability.

Two groups of columns are divided into both sides, track, and are arranged on sole plate, and sole plate is embedded in underground.Often organize column Being parallel to each other by two and column separated by a distance composition, two root posts are connected by crossbeam, and every root post is by three Being grouped into: bottom is the part (abbreviation base component) being connected with ground base, middle part is middle short circuit, and top is liftable band Scale inner tube (abbreviation inner tube).Inner tube top is connected as a single entity at flange by bolt with liftable crossbeam, enters with crossbeam simultaneously Row lifting, inner tube is marked with graduated scale, and for indicating the height of liftable crossbeam present position, effect is directly perceived, conveniently uses Person operates.Base component and middle short circuit use Flange joint, inner tube to dock only with flange with middle short circuit, do not carry out even Connect.

Middle short circuit uses thick-walled seamless steel pipes, and when door frame is clashed into, column is unlikely to deform or destroys and cause thing Therefore, strengthen road safety and the steadiness of door frame.Middle short circuit inner sleeve nylon gum cover, facilitate inner tube location and reduce inner tube with The friction of middle short circuit, prevents from affecting inner tube lifting because of rust.Sheath structure is made in short circuit bottom, facilitates inner tube to position, when When inner tube raises, pin inner tube, it is ensured that inner tube is vertical.Wei Lakou is made in inner tube bottom simultaneously, when inner tube rises to highest point, micro- Loudspeaker type bottom coordinates tightly with sheath inner tube, prevents inner tube from coming off, it is ensured that inner tube and the stability of crossbeam.

Liftable crossbeam uses double beam structure, uses short support to reinforce between two crossbeams, increases steadiness, on crossbeam Portion hangs limit for height nameplate, flashing light, wireless bridge shooting video record instrument and bluetooth read head.Wireless bridge shooting video record Instrument can assist road administration department to capture illegal vehicles peccancy, and sends data at neighbouring supervision of law enforcement.Bluetooth read head can be with Bluetooth handle in special vehicle is matched, and uses bluetooth to open liftable crossbeam, adjusts beam height, facilitates vehicle to lead to OK.The most also remote control, the electronics mode such as swipe the card can be used to carry out remotely or electric start liftable crossbeam according to actual needs, Realize digitized law enforcement office etc..

Often by group column, motor and hydraulic system are set, utilize the height of the support force two-way adjustment limit for height door frame of hydraulic stem Degree, hydraulic means stable working, noise is little, can steadily adjust the height of limit for height door frame.Hydraulic drive can use Automated condtrol With Artificial Control two ways, using motor to carry out automatization's supercharging, time saving and energy saving, speed is fast.When after motor power-off, pass through Pedal controls hydraulic system, opens accumulator, and hydraulic oil makes oil cylinder to move up and down by oil path block and valve block, and then drives Hydraulic stem moves up and down, to adjust the height of limit for height door frame.

Detailed description of the invention

Illustrate with Fig. 1

When special vehicle passes through, pressing 12 hydraulic means buttons, start 11 motor, 13 hydraulic stems slowly rise, simultaneously Drive 6 liftable crossbeams and 4 inner tubes with a scale to synchronize to rise, observe the scale in 7 inner tubes with a scale, reach the height of requirement Time, close 11 motor, 13 hydraulic stems lock automatically, it is ensured that 3 liftable crossbeams are stable at the height needed.Treat that special vehicle is complete Full by, open 11 motor, 13 hydraulic stems slowly decline, under driving 6 liftable crossbeams and 7 inner tubes with a scale to synchronize simultaneously Fall, observes 7 inner tube high scales with a scale, when reaching the height needed, closes 11 motor, and 10 hydraulic stems lock automatically, limit for height Mast height is reduced to the height needed.

When motor can not use for some reason, artificial foot-operated 7 pedals, 13 hydraulic stems slowly rise, and drive 6 can rise simultaneously Fall crossbeam and 7 inner tubes with a scale synchronize to rise, and observe the scale in 7 inner tubes with a scale, when reaching the height of requirement, close 11 electricity Motivation, 13 hydraulic stems lock automatically, it is ensured that 6 liftable crossbeams are stable at the height needed.Treat that special vehicle passes through completely, lift 10 pedals, 13 hydraulic stems slowly decline, and drive 6 liftable crossbeams and 7 inner tubes with a scale to synchronize to decline simultaneously, observe 7 bands and carve Degree inner tube high scale, when reaching the height needed, closes 11 motor, and 13 hydraulic stems lock automatically, and limit for height mast height reduces To the height needed.

Illustrate with Fig. 2

When 1 inner tube with a scale rises with hydraulic stem, 1 inner tube with a scale, inside 4 middle short circuits, sequentially passes through 5 sheath Structure and 3 nylon gum covers, rise to the height needed, when 1 inner tube with a scale rises to highest point, under 1 inner tube with a scale Portion 7 micro-loudspeaker O-shaped structure and the contact of 5 sheath close structures, coordinate tight, prevents inner tube from coming off inclination.
