Description

A kind of automobile chassis elevator with function of safety protection

Technical field

The utility model relates to motor vehicle repair equipment technical fields, have function of safety protection more particularly to one kind Automobile chassis elevator.

Background technique

With gradually increasing for automobile, the quantity of Auto repair shop also gradually increases, for the elevator of Auto repair shop Using more universal, the too busy to get away elevator of repairing automobile chassis.

Elevator used in traditional Auto repair shop is to utilize hydraulic cylinder drive cylinder piston rod, liquid presses piston pole Slide unit rise and fall are driven, slide unit drives trailing arm clump and plays lifting effect.Now most of lifting machine is all that slide unit setting exists The inside of column is connected by sliding block between slide unit and column, needs often to do lubricated to sliding block thus, even if in this way Still can make to generate certain friction between sliding block and column, lifting machine lifting is not that especially steadily, equipment, which is used for a long time, to be produced Raw abrasion.In addition present double-column lifter both sides slide unit in lifting process can inevitably generate difference in height, at present this Kind difference in height mainly uses wirerope to pass in and out leveling, and structure is complex, and wirerope is easily broken off, and is not special Safety.

Application No. is CN201720099549.X, patent disclose a kind of two post lifts for motor vehicle repair, Including support baseboard, the upper surface two sides of the support baseboard are inlaid with sliding rail, and the left and right sides is inlaid with sliding block on the sliding rail, Bottom plate is installed, the upper surface of the bottom plate is inlaid with LED light, and the back side of bottom plate is fixedly installed with lithium battery, institute among sliding rail It states and is also connected with power amplifier between the power output end of lithium battery and LED light；The upper surface of the sliding block is fixedly installed with Support base is fixedly installed with the first hydraulic lifting post and the second hydraulic lifting post, first hydraulic lifting on the support base The upper surface of column and the second hydraulic lifting post is inlaid with cover board；The side of the support baseboard is also fixedly installed with control panel, The upper surface of the control panel is inlaid with liquid crystal display and control button, and inside is fixedly installed with core controller, described The input terminal of core controller is connected with data acquisition module, and output end connects electronic switch and hydraulic unit driver.But it is this Lifting machine still has many security risks, for example hydraulic system is damaged suddenly and may cause automobile and directly fall down, by automobile The worker that lower section is repaired injures by a crashing object.

Utility model content

The purpose of this utility model is that: lifting device the asking there are security risk in order to solve orthodox car repair shop Topic, the utility model provide a kind of automobile chassis elevator with function of safety protection.

The utility model specifically uses following technical scheme to achieve the goals above:

A kind of automobile chassis elevator with function of safety protection is successively erected at including base, fixation from bottom to up Column on base, the limit plate being fixedly connected with column, the speed reducer being fixedly connected with limit plate and driving speed reducer Motor, the column are hollow tubular structure, and the direction of axis line of column is provided with guide groove, the guide groove and column Inner hole connect, be vertically arranged with screw rod in the inner hole of the column, the screw rod upper end is defeated through limit plate and speed reducer Shaft is fixedly connected, and the lower end of the screw rod and the base are rotatablely connected, and is arranged with supporting block, the support on the screw rod Block moves up and down under the driving of screw rod, and the supporting block extends to outside column after passing through the guide groove, on the column Multiple security protection blocks are provided with, are provided with the through-hole with column clearance fit on security protection block, on the security protection block It is provided with the limiting slot wide with guide groove, the limiting slot and the through-hole are connected.By the way that security protection block is arranged, this dress is allowed Setting can allow the operator below the automobile after liter act can be more by the way that safe cushion block is arranged below automobile after the lifting Add safety.

Working principle: the present apparatus two being separately positioned on the two sides of automobile, using the rising of supporting block by automobile chassis It rises and raises, the security protection block below supporting block will be located at when reaching suitable height and rotates 180 degree, allow security protection Block directly pads below supporting block, in this way regardless of whether the elevating mechanism of supporting block damages, has entity component below supporting block As support, the operator below the present apparatus will not be injured.

Further, the supporting block is set as T-shaped structure, and the supporting block is from left to right followed successively by targeting part, connects Socket part point and support section, the support section are elongate in shape, and one end of the coupling part is vertically set on the branch The centre of support part point, the other end of the coupling part are fixedly connected with targeting part, and the targeting part is cylindrical structure, The outer inner hole clearance fit through with column of the targeting part, the coupling part passes through the guide groove, along guide part The direction of axis line divided is provided with the tapped through hole to match with screw rod.By setting T-shaped structure for supporting block, supporting block is allowed Screw thread lifting part and support section separate, make support section and automobile chassis contact area bigger, improve the steady of the present apparatus It is qualitative.

Further, the security protection block is rectangle structure, and it is anti-that the through-hole and limiting slot are arranged at safety The right of protecting block.

Further, the speed reducer is helical speed reduction gear, and the motor is set as three line asynchronous machines, the electricity The casing of motivation is fixedly connected with the cabinet of the speed reducer.It is helical speed reduction gear by setting speed reducer, allows the present apparatus Rise and decline during can be more steady, speed is slower, makes the present apparatus safer when liter act automobile.

Further, the base is square structure, and the center of base, the material of the base is arranged in the column For cast iron.It is that cast iron improves base weight by setting base, improves the weight of the promoted vehicle of the present apparatus, avoid tumbling.

The beneficial effects of the utility model are as follows:

1, by setting security protection block, the present apparatus is allowed safe cushion block can be set by automobile lower section after the lifting, Allow the operator below the automobile after liter act can be safer.

2, the present apparatus two are separately positioned on the two sides of automobile, are lifted the chassis liter of automobile using the rising of supporting block Come, the security protection block below supporting block will be located at when reaching suitable height and rotates 180 degree, makes security protection block direct Pad, in this way regardless of whether the elevating mechanism of supporting block damages, has entity component as branch below supporting block below supporting block Support, the operator below the present apparatus will not be injured.

3, by setting T-shaped structure for supporting block, the screw thread lifting part of supporting block and support section is allowed to separate, allows branch Support part point is bigger with automobile chassis contact area, improves the stability of the present apparatus.

4, by setting speed reducer be helical speed reduction gear, allow the present apparatus rising and decline during can more put down Surely, speed is slower, makes the present apparatus safer when liter act automobile.

5, it is that cast iron improves base weight by setting base, improves the weight of the promoted vehicle of the present apparatus, avoid tumbling.
