Description

Secondary protection device for lifting vehicle platform

Technical Field

The utility model relates to a lift ride technical field specifically discloses a lift ride secondary protection device.

Background

The lifting vehicle platform is a mechanical device for lifting a vehicle, the lifting device on the top end of the lifting frame lifts the platform carrying the vehicle, the platform is hung through the safety hook above after being lifted to a certain height, and safety accidents caused by falling of the vehicle due to breakage of a rope or a chain when maintenance is carried out are prevented.

For example, application number is 2011204142003's utility model patent just discloses a safe couple group of lift sideslip formula parking equipment, including rotate install on the support before, the back couple subassembly, it has the connecting rod to articulate between preceding, the back couple subassembly, be located fixed mounting on the support of back couple subassembly one side and have the fixing base, install electromagnet assembly on the fixing base, be equipped with the spout on the fixing base and install the slider through sliding fit, be the magnetism cooperation between slider and the electromagnet assembly, it has the push rod to articulate between slider and the back couple subassembly. The utility model discloses a safety hook is hung when being used for the lift platform, has convenient to use, can prevent completely that the parking platen from taking place to fall, has effectively ensured the safety of parking the vehicle. However, this type of safety hook set only hooks the platform when it is lifted to the top, so as to prevent it from falling down, but cannot prevent the platform from falling down once the rope or chain breaks during the lifting of the platform. Therefore, to the above-mentioned not enough of current lift sideslip formula parking equipment's safe couple group, this application has proposed one kind and can play the secondary protection device of lift ride that better prevents weighing down the effect in the lift process.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the safety hook group of the existing lifting and horizontal moving type parking equipment cannot prevent falling during the lifting process, and designing a lifting vehicle platform secondary protection device.

The utility model discloses a realize through following technical scheme:

the utility model provides a lift ride secondary protection device, includes the installation casing, the inside of installation casing is rotated and is provided with the drum, and is provided with the clockwork spring that realizes automatic rolling in the drum, be provided with the protection rope that is connected with lift ride middle platform on the drum, the excircle face of ring baffle on the drum evenly is provided with a plurality of latches, rotate in the installation casing and be connected with the card condition with latch matched with, be connected with the brace on the card condition, the brace stretches out the installation casing and receives lift ride upper rope or the effect of chain.

This lift platform secondary protection device is connected with the platform in the lift platform through the protection rope on the drum, and the lift platform will block the condition and separate with the latch on the drum through the brace at normal operating in-process, consequently the drum can not brake the locking at normal operating in-process. In case rope or chain fracture in the operation in-process of lift platform, the effort that the brace received this moment disappears, and the card condition of this moment rotates and is acted on with the latch on the drum mutually, has realized the braking of drum, and because the platform is connected with the drum through the protection rope to can play the braking effect to the decline of platform, prevent that it from taking place to fall at the operation in-process.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict. The present application will be described in detail with reference to the accompanying drawings 1 to 4, in conjunction with examples.

Example 1

This embodiment 1 provides a secondary protection device for a lift truck platform, and referring to fig. 1 and fig. 2, the main body of the device includes a mounting housing 100, the mounting housing 100 is composed of a front cover plate and a rear U-shaped plate through screw connection, and the left and right ends of the mounting housing 100 are opened.

The installation shell 100 is rotatably connected with a protection wire coil 200 through a pin shaft 103, a protection rope connected with a platform in the lifting vehicle platform is arranged on the protection wire coil 200, ring baffles 201 are arranged at the front end and the rear end of the protection wire coil 200, and a plurality of limiting clamping teeth 202 are uniformly connected to the outer circular surface of the ring baffles 201 close to one side of the U-shaped plate.

Referring to fig. 2 and 3, a clamping bar 101 matched with a limit latch 202 is rotatably connected in the mounting housing 100, a pull bar 102 is rotatably connected to the movable end of the clamping bar 101, and the end of the pull bar 102 extending out of the mounting housing 100 is acted on a rope or chain in the lift car platform. During normal operation, the pull-strip 102 is acted on by the rope or chain to pull the card member 101 outwardly so that the card member 101 does not engage the limit latch 202. Once the force applied by the rope or chain to the pulling strip 102 disappears after the rope or chain is broken, the clamping member 101 will rotate downwards under its own weight and be clamped into the gap between two adjacent limiting latches 202, so as to perform an emergency braking function on the protection wire coil 200, and then perform an anti-falling function on the platform through the protection rope.

In addition, in order to realize that the protection rope on the protection wire coil 200 can be automatically wound when the platform is lifted, referring to fig. 4, an inner groove 203 is further formed in the protection wire coil 200, and a spiral spring 204 capable of automatically winding the protection wire coil 200 is disposed in the inner groove.
