Abstract
A kind of ladder for large-scale grab bucket maintenance, it is mainly made up of a moveable chassis, the scalable cat ladder that is arranged on chassis by a support, and described chassis is mounted below two and orients wheels and the universal wheel of two strap brakes；Described scalable cat ladder by rack-mount, that be made up of oscillating bearing, the slew gear that cat ladder holds up or keep flat can be realized be connected with support;Being provided with a bracket fixing end for holding scalable cat ladder on described side, chassis, described scalable cat ladder is fixed end and is provided with and can easily realize cat ladder traverse and vertical balancing weight；The invention have the characteristics that to shrink at ordinary times and keep flat, taken up space little；Can open easily during use, there is simple in construction, easy to use, safe and reliable, wind-proof performance is good, is easy to features such as depositing.
Description
Technical field
The present invention relates to ladder during a kind of large-scale grab bucket upper and lower for operating personnel, belong to the ladder technical field of a kind of operation of climbing.
Background technology
In harbour, harbour production process, often encounter and to climb large-scale grab bucket (vertical height is more than 6 meters).If directly climbing, its process lacks safeguard protection, there is bigger potential safety hazard.For the sake of security, operating personnel typically first to set up scaffold, so process is loaded down with trivial details, operating efficiency is low.
Summary of the invention
It is an object of the invention to the deficiency overcoming prior art to exist, and provide a kind of simple in construction, easy to use, safe and reliable, be easy to the ladder for large-scale grab bucket maintenance deposited.
It is an object of the invention to complete by following technical solution: the described ladder for large-scale grab bucket maintenance, it is mainly made up of a moveable chassis, the scalable cat ladder that is arranged on chassis by a support, and described chassis is mounted below two orientation wheels and the universal wheel of two strap brakes；Described scalable cat ladder by rack-mount, that be made up of oscillating bearing, the slew gear that cat ladder holds up or keep flat can be realized be connected with support.
Being provided with a bracket fixing end for holding scalable cat ladder on described side, chassis, described scalable cat ladder is fixed end and is provided with and can easily realize cat ladder traverse and vertical balancing weight.
Described scalable cat ladder is at least formed by connecting by spring pin locking by three-section ladder, and the header arrangement of described extension type cat ladder has the catching device that can mount, and this catching device is provided with one and can pull out and catch on the hook on balancing weight handle.
Being provided above of described scalable cat ladder one can be blocked above grab bucket so that the bayonet socket preventing cat ladder from waving.
It is provided with on described chassis avris when cat ladder is vertically placed, fixes, for scalable cat ladder, the draw-in groove that end is placed.
The present invention have simple in construction, easy to use, safe and reliable, be easy to features such as depositing.
Accompanying drawing explanation
Fig. 1 be cat ladder of the present invention keep flat structural representation.
Fig. 2 is that the A of Fig. 1 is to structural representation.
Fig. 3 be cat ladder of the present invention vertically place working state schematic representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1-3, ladder for large-scale grab bucket maintenance of the present invention, it mainly by a moveable chassis 1, be arranged on the One On The Chassis scalable cat ladder 3 by a support 2 and form, described chassis 1 is mounted below two orientation wheels 4 and the universal wheel 5 of two strap brakes, it can easily arrive ladder operating position, and is braked；Described scalable cat ladder 3 by be arranged on support 2, that be made up of oscillating bearing, the slew gear 6 that cat ladder holds up or keep flat can be realized be connected with support.
Being provided with a bracket 7 fixing end for holding scalable cat ladder on described one end, chassis 1, described scalable cat ladder is fixed end and is provided with and can easily realize cat ladder traverse and vertical balancing weight 8.
Described scalable cat ladder 3 for existing, be at least formed by connecting by spring pin locking by three-section ladder; the header arrangement of described extension type cat ladder 3 has the catching device that can mount; it is provided with one on this catching device and can pull out and catch on the hook on balancing weight handle, the safety of its energy total process protective operating personnel.
Being provided above of described scalable cat ladder 3 one can be blocked above grab bucket so that the bayonet socket preventing cat ladder from waving, and it can be prevented effectively from ladder double swerve.
It is provided with when cat ladder is vertically placed on described chassis 1 avris, fixes, for scalable cat ladder, the draw-in groove that end is placed.
The specifically used method of the present invention is:
1, by hand push of the present invention to job site；
2, cat ladder is stretched out to the length needed, and confirm that spring pin is locked；
3, on the head of cat ladder, hang up properly catching device, catching device hook is pulled out to catching on counterweight handle；
4, utilize cat ladder to fix the handle of end, cat ladder is carried away and returned back to vertical position from fixing seat, and cat ladder is fixed end be placed in draw-in groove；
5, adjust the position of the present invention, make the bayonet socket above cat ladder block the top of grab bucket, and dolly is braked；
6, catching device hook is connected with safety belt；
7, operating personnel just can climb.
After task completes, recover by above-mentioned reverse procedure.
Use the present invention can the upper and lower grab bucket of convenient working personnel, and for its provide overall process safeguard protection.
