Abstract

The utility model relates to a telescopic safety ladder, which comprises a main ladder, a ladder and a guardrail arranged on the outer side of the main ladder, and is characterized in that one side of the main ladder is provided with a connecting support which is connected with the outside world; a cross beam on the end of the main ladder is fixedly connected with a pulley; the pulley is connected with the ladder by a rope, and the other end of the rope is connected with a fixed object on the ground; the side frame of the main ladder is symmetrically provided with a guide bent plate; the ladder is arranged in a track formed by the guide bent plate; the cross beam on the lower end of the main ladder is provided with a rotary hook; one end of the hook is connected with the rope; the rope is wound on the pulley; the other end of the rope is connected with the fixed object on the ground; the cross beam of the main ladder which is connected with the rope side is provided with a limit plate; and a baffle extends from the hook on the offside of the limit plate. Therefore, the telescopic safety ladder has the advantages of simple structure, convenient assembly and disassembly, small occupied space and convenient use, thereby saving the installation space of the equipment, and improving the working efficiency.

Description

Telescopic safe hanging ladder
Technical field
The utility model relates to a kind of telescopic safe hanging ladder that is used on the main equipment.
Background technology
Main equipment originally is widely used in fields such as forging and pressing, large-scale generating equipment, boats and ships at present, and for making things convenient for the maintenance of equipment, this kind equipment has complete cat ladder mostly, and the maintenance personal can arrive the equipment top along safe cat ladder and detect and keep in repair.Existing safe cat ladder is divided into two kinds substantially: a kind of employing integral structure, and safe cat ladder directly leads to ground, and this structure is easy to use, but it is bigger to take up room; Another kind of main ladder and the hanging ladder structure of adopting promptly hangs a hanging ladder in the bottom of main ladder, though the safe cat ladder save space of this kind is to use trouble, always shifts from one place to another, and prolongs overhead time, influences operating efficiency.
Summary of the invention
The technical problem that exists in the known technology provides a kind of simple in structure, easy installation and removal to the utility model, telescopic safe hanging ladder little, easy to use takes up room in order to solve.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of telescopic safe hanging ladder, comprise main ladder, hanging ladder and the protective guard that is installed in the main ladder outside, it is characterized in that: a side of described main ladder is provided with and the extraneous connection support that is connected, be fixed with pulley on the end crossbeam of main ladder, pulley connects hanging ladder by rope, the other end of rope connects ground fixed object, be arranged with the guiding bent plate on the main side of the ladder frame, hanging ladder is installed in the formed track of guiding bent plate, on the following end floor beam of main ladder, rotating hook is installed, one end of hook is connected with rope, rope is on pulley, the other end of rope connects ground fixed object, is fixed with limiting plate on the terraced crossbeam of the master of connecting rope side, and the hook of limiting plate offside is extended with baffle plate.
The advantage that the utlity model has with good effect is: because the utility model is provided with and the extraneous connection support that is connected in a side of main ladder, make the utility model easy installation and removal, be fixed with pulley on the end crossbeam of main ladder, pulley connects hanging ladder by rope, be arranged with the guiding bent plate on the main side of the ladder frame, hanging ladder is installed in the guiding bent plate, on the following end floor beam of main ladder, rotating hook is installed, one end of hook is connected with rope, rope is on pulley, be fixed with limiting plate on the terraced crossbeam of the master of connecting rope side, the hook of limiting plate offside is extended with baffle plate, and limiting plate and baffle plate can guarantee that arriving the desired position be location and support.Therefore simple, the easy installation and removal of said structure, take up room little, easy to use, thereby saved the installing space of equipment, increase work efficiency simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the lateral view of Fig. 1;
Fig. 4 is an A-A sectional view among Fig. 2.
Among the figure: 1, main ladder; 1-1, connection support; 1-2, crossbeam; 2, hanging ladder; 3, protective guard; 4, pulley; 5, rope; 6, guiding bent plate; 7, hook; 7-1, baffle plate; 8, rope; 9, limiting plate.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 to Fig. 4, a kind of telescopic safe hanging ladder, comprise main ladder 1, hanging ladder 2 and the protective guard 3 that is installed in main terraced 1 outside, side at main ladder 1 is provided with and the extraneous connection support 1-1 that is connected, on the end crossbeam 1-2 of main ladder 1, be fixed with pulley 4, pulley 4 connects hanging ladder 2 by rope 5, the other end of rope 5 connects on the accessibility fixed object of staff, on main terraced 1 side frame, be arranged with guiding bent plate 6, hanging ladder 2 is installed in the guiding bent plate 6 formed tracks, hanging ladder 2 can slide up and down along this bent plate 6 that leads, on the following end floor beam 1-2 of main ladder 1, rotating hook 7 is installed, this hook 7 adopts dissymmetrical structure, hook 7 be not subjected to keep plumbness under the external force effect, one end of hook 7 is connected with another root rope 8, rope 8 is on pulley 4, the other end of rope 8 connects on the accessibility fixed object of staff, on main terraced 1 the crossbeam 1-2 of connecting rope 8 sides, be fixed with limiting plate 9, the hook 7 of limiting plate offside is extended with baffle plate 7-1, and limiting plate 9 and baffle plate 7-1 guarantee that the location when arrival needs the position can support like this.
Principle explanation: when hanging ladder 2 during on ground, if want to promote hanging ladder 2, at first pull rope 5 sons, the track that rope 5 pulling hanging ladders 2 form along guiding bent plates 6 moves upward, and treats that hanging ladder 2 is raised to drop rope 8 when being fit to height, makes hook 7 go to level, unclamp rope 5 sons this moment then, hanging ladder 2 falls on the hook 7 naturally, because the effect of limiting plate 9 and baffle plate 7-1 makes hanging ladder be suspended on main ladder 1, this moment, hanging ladder can not move downward.When needs put down hanging ladder 2, at first spur rope 5, hanging ladder 2 is risen, because hook 7 is anisopleual, makes it go to vertical direction under its action of gravity, at this moment slow with one's hands loosening slowly rope 5 sons, hanging ladder 2 just moves downward along the track that guiding bent plate 6 forms, until ground.
