Description
Technical field
The utility model belongs to the detecting test of vehicle technical field, especially relates to a kind of safety structure of auto hoist.
Background technology
Auto hoist is the automobile repair machinery for automobile maintenance industry.Auto hoist is being brought into play vital effect in the vehicle maintenance and repair maintenance, car load overhaul and maintenance all be unable to do without hydraulic jack.Along with the increase of China's auto sale amount, auto hoist is as the important tool of vehicle maintenance and repair, and demand also increases greatly.Auto hoist is used for automobile lifting in vehicle maintenance and repair, thereby makes things convenient for the repairman that automobile is placed under repair.Because the auto hoist weight of carrying automobile, and the repairman is usually in maintaining bottom of automobile work, thereby the safety device of auto hoist plays vital effect for the safety of lifting machine.
The safety device of auto hoist structure generally has two kinds of structures: a built-in insurance, as Figure 1-3, generally comprise safety device 1, column 2, power unit 3, oil pipe backplate 4, trailing arm 5, slide 6, oil cylinder 7, two columns 2 are oppositely arranged, oil pipe backplate 4 places two column 2 bottoms, two columns 2 are rectangular-shaped, cross-sectional plane is " C " type groove shape, be provided with slide 6 in the groove, trailing arm 5 can move up and down at slide 6, trailing arm 5 connects the power unit 3 in column 2 outsides, power unit 3 drives trailing arm 5 up-and-down movement on slide 6, be provided with safety device between trailing arm 5 and the column 2, traditional safety device 1 comprises insurance tooth bar 11 and insurance lock dog 12, safety device 1 is fixed on column inside, namely in " C " type groove, safety device is that the side is stressed, work long hours and to cause its distortion because of unbalance stress, greatly reduce the service life of lifting machine, whether safety device plays a role can only be leaned on sound discrimination, can't observe intuitively, and because the space of column inside is little, the safety device of lifting machine is safeguarded can be very difficult.
Another kind of structure is the external safety structure, shown in Fig. 4-6, to insure on two fins 13 that tooth bar 11 is arranged on each column " C " type channel opening place, the mode of operation of observing safety device so intuitively, easy to maintenance, but insurance tooth bar 11 structures of existing this safety device as shown in Figure 7, its processing technology is generally: punch press punching one punching is complete behind first shear one shear is using the large mold moulding afterwards, complex process, insufficient strength, insufficient strength show above the thickness of sheet material, and this part is with 2～3mm sheet material, and the centre is hollow, so no matter still all can damage insurance tooth bar 11 in the transportation in the use; With the insurance lock dog 12 of its coupling as shown in Figure 8, this part processed complex, generally adopting the gas cutting profile then is to come the circular arc of assurance piece with the diameter of milling machine milling cutter, processing gets up to damage cutter, processed complex.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of processing simple for the defective that overcomes above-mentioned prior art existence, the safety structure of the auto hoist that intensity is firm.
The purpose of this utility model can be achieved through the following technical solutions: a kind of safety structure of auto hoist, lifting machine comprises two columns that are oppositely arranged, power unit, bay-lift, trailing arm, described bay-lift is arranged on the column, described trailing arm is connected with bay-lift, described power unit drives bay-lift and moves up and down, described safety structure comprises insurance tooth bar and insurance lock dog, the insurance tooth bar is provided with four, be separately positioned on the fin of two column opposite faces, described insurance lock dog is installed on the described bay-lift by connecting panel, it is characterized in that, described insurance tooth bar is comprised of the insurance pawl of the some projections that arrange on strip shape solid steel plate and this steel plate, described steel plate and a plurality of insurance pawl integrated setting, pawl is supporting engages with insurance for described insurance lock dog.
The thickness of described steel plate is 5mm.
Described insurance pawl comprises the U-shaped opening of a broadside, and the hypotenuse that connects the U-shaped opening of this broadside and steel plate.
The structure of described insurance lock dog is complementary with the structure of insurance pawl, and its bottom surface is the plane.
Described insurance lock dog is arranged on the connecting panel, and this connecting panel is provided with and promotes the push rod that the insurance lock dog inserts insurance pawl internal locking or extracts the release of insurance pawl out.
Described insurance lock dog is provided with fixed orifice and axis hole, and described fixed orifice is fixed on the connecting panel, and described axis hole connects push rod.
The utility model adopts the once property punch forming on punch press of 5mm band steel, because as connecting the connecting strap respectively insure pawl, so intensity is good with solid steel plate, transportation can insurance of damage tooth bar yet, owing to the improvement of its structure, get final product with 2 faces of milling machine processing after the safety block gas cutting profile in addition.Compared with prior art, the utlity model has following advantage;
1. auto hoist is compared the shortcoming of having avoided judging with sound safety structure after improving with the auto hoist of the built-in safety structure of tradition.
2. auto hoist is safer than the auto hoist of traditional built-in safety structure after improving, and changes former double insurance into four insurances, and insurance is directly perceived as seen.
3. the auto hoist safety block after improving is more easy to process than the safety block of the auto hoist of traditional external safety structure, uses flexibly.
4. the auto hoist insurance tooth bar after improving is better than the insurance tooth bar intensity of the auto hoist of traditional external safety structure, and processing technology is simple, and has avoided installing and the damageable situation of transportation appearance.
