Abstract
The utility model discloses a guide rail for a car door or a floor door of an elevator. The guide rail comprises a guide rail (2) fixedly connected to the upper ridge frame (1) of the car door or the floor door, the guide rail (2) adopts a hollow structure, and a downward convex stop dog (2.2) is arranged on the outer side on the lower end surface of the guide rail (2) and extends along the length direction of the guide rail (2). The guide rail has simple structure; and a roller is effectively prevented from dropping off, so that more stable operation of a door hanging board and better stability and reliability of the elevator can be ensured.
Description
Technical field
The utility model relates to elevator accessory technical field, particularly a kind of elevator cage door or layer door guide rail.
Background technology
The door of car formula elevator comprises the gate of being located on the car and is located at the layer door of each layer of building, the structure of gate or layer door gear comprises the upper sill frame fixing with building, be fixed on the upper sill frame guide rail and with the door strap of guide rail sliding block joint, be fixed with pulley and roller on the door strap, pulley and roller are located at guide rail upper surface and lower surface respectively, and pulley and roller all roll along guide rail, thereby realize the folding of elevator cage door or layer door.Common guide rail structure has two kinds on the market: a kind of is solid guide rail, has not only wasted material, and has increased weight, and relatively effort is installed.Another is the guide rail by the direct bending forming of upper sill frame, the processing technology more complicated of this bending forming structure, and when the gate of elevator or the folding of layer door, guide rail and upper sill frame can produce vibrations together, and noise ratio is bigger.
For this reason, occurred a kind of hollow guide rail structure on the market, not only reduced raw-material use, saved productive costs, it is also very convenient to install and transport, and has reduced the noise when elevator moves.But roller and guide rail lower surface are plane contact, and when being subjected to greater impact, roller easily causes and comes off, and then elevator reliability of operation and stability have been subjected to influence.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of simple in structure, can prevent effectively that roller from coming off, can guarantee elevator cage door that elevator is stable or layer door guide rail.
The technical scheme in the invention for solving the above technical problem is: a kind of elevator cage door or layer door guide rail, comprise the guide rail on the upper sill frame that is fixedly connected on gate or layer door, described guide rail is a hollow structure, the outside of the lower surface of described guide rail is provided with down protruding block, and described block extends along the length direction of described guide rail.
Compared with prior art, advantage of the present utility model is: the outside of the lower surface of this guide rail is provided with down protruding block, and this block is along extending on the length direction of guide rail.Like this, this block can carry out spacing to the roller that is arranged on the guide rail lower surface, can prevent effectively that roller from coming off, and has guaranteed that the operation stability and the reliability steady more, elevator of door strap is also better.
As improvement, the upper surface of described guide rail for the door strap that is installed in elevator on the arc surface that matches of the shape of pulley.Like this, can effectively reduce the friction between pulley and the guide rail, make the operation of door strap more steady.
As preferably, described block and described guide rail are integral structure.Like this, not only process more conveniently, the structure of guide rail is also more firm.
Description of drawings
Fig. 1 is the left TV structure scheme drawing of gate or layer door gear.
Fig. 2 is the structural representation that the utility model elevator cage door or layer door are used guide rail.
Among Fig. 1-2: 1 upper sill frame, 2 guide rails, 2.1 arc surfaces, 2.2 blocks, 3 door straps, 4 rollers, 5 pulleys.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in Figure 1, 2, a kind of elevator cage door or layer door guide rail, comprise the guide rail 2 on the upper sill frame 1 that is fixedly connected on gate or layer door, described guide rail 2 is a hollow structure, the outside of the lower surface of described guide rail 2 is provided with down protruding block 2.2, and described block 2.2 extends along the length direction of described guide rail 2.Like this, this block 2.2 can carry out spacing to the roller 4 that is located at the guide rail lower surface, can prevent effectively that roller 4 from coming off.
In this specific embodiment, the upper surface of described guide rail 2 for the door strap 3 that is fixed on elevator on the arc surface 2.1 that matches of the shape of pulley 5.The arc surface 2.1 of this guide rail 2 and the shape of pulley 5 match, and can effectively reduce the friction between pulley 5 and the guide rail 2, make the operation of door strap 3 more steady.
In this specific embodiment, guide rail 2 is fixedly connected on the upper sill frame 1 by screw bolt and nut.
In this specific embodiment, described block 2.2 is an integral structure with described guide rail 2.Like this, not only process more conveniently, the structure of guide rail 2 is also more firm.
The utility model not only is confined to above embodiment, and its concrete structure allows variation, as: the shape of the roller that matches according to actual and guide rail 2 is different, and the upper surface of guide rail 2 also can be a plane; The inboard of described guide rail 2 is provided with concave surface, convex surface or the plane that the upper sill frame 1 with gate or layer door matches, etc.All various variations of being done in the protection domain of the utility model independent claims are all in the utility model protection domain.
Claims (3)
1. elevator cage door or layer door guide rail, comprise the guide rail (2) on the upper sill frame (1) that is fixedly connected on gate or layer door, described guide rail (2) is a hollow structure, it is characterized in that: the outside of the lower surface of described guide rail (2) is provided with down protruding block (2.2), and described block (2.2) extends along the length direction of described guide rail (2).
2. elevator cage door according to claim 1 or layer door use guide rail, it is characterized in that: the upper surface of described guide rail (2) be with the door strap that is installed in elevator (3) on the arc surface (2.1) that matches of the shape of pulley (5).
