Abstract

The invention relates to a guide rail pair with a self-locking function. The guide rail pair comprises a sliding block, a guide rail, a wedge block and a wedge block lifting unit, wherein the sliding block is arranged on the guide rail in a sliding manner, a cavity is arranged on one side of a surface in which the sliding block is in contact with the guide rail, the wedge block is arranged in the cavity, and the wedge block lifting unit is connected with the wedge block in a driving manner to ensure that the wedge block moves up and down in the cavity. According to the guide rail pair, the emergency brake can be realized under the condition of power failure, and the operation safety is improved. The guide rail pair is simple in structure and low in cost.

Description

A kind of guiding pairs
Technical field
The present invention relates to a kind of guiding pairs with auto-lock function.
Background technique
At present rolling guide-rail pairs does not all have auto-lock function, and system usually can be because of the reason of power-off suddenly when operation, and causes the damage of system, and therefore a lot of users, in order to improve the Security of system cut-off, usually need to increase very expensive power-off protection apparatus.
Summary of the invention
The object of the invention is to address the above problem, and a kind of guiding pairs with auto-lock function is provided, and specifically by following technological scheme, is realized.
A kind of guiding pairs, comprise slide block, guide rail, voussoir and voussoir lifting unit, described slide block is slidably arranged on guide rail, surface of contact one side of slide block and guide rail is provided with cavity, described voussoir is placed in this cavity, and described voussoir lifting unit drives to be connected with described voussoir it is moved up and down in cavity.
Described a kind of guiding pairs, its further design be, described voussoir lifting unit comprises electromagnet and spring, described electromagnet is placed on slide block and is relative with described voussoir, described spring connects described voussoir and slide block.
Described a kind of guiding pairs, its further design be, described voussoir be provided with corresponding with two glide directions of slide block two domatic, described domatic slope angle is less than the friction angle between slide block and voussoir.
The present invention can realize emergency braking in the situation that of power-off, has improved operational security, and the present invention is simple in structure, and cost is lower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is internal structure schematic diagram of the present invention.
Embodiment
Below in conjunction with Figure of description and specific embodiment, the present invention is further described.
This guiding pairs comprises slide block 1, guide rail 2, voussoir 3 and voussoir lifting unit 4, slide block 1 is slidably arranged on guide rail, slide block 1 is provided with cavity 12 with surface of contact one side of guide rail 2, voussoir is placed in this cavity 12, and voussoir lifting unit 4 drives to be connected with voussoir 3 it is moved up and down in cavity 12.Voussoir lifting unit 4 comprises electromagnet 41 and spring 42, and electromagnet 41 is placed on slide block 1 and is relative with voussoir 3, spring 42 elasticity connecting wedges 3 and slide blocks 1.Voussoir 3 be provided with corresponding with two glide directions of slide block two domatic, domatic slope angle α is less than the friction angle between slide block and voussoir.When slide block normally slides on guide rail, electromagnet energising, voussoir is that irony is promoted by adhesive under the magnetic force effect of electromagnet, now voussoir is separated with guide rail; When power-off, the demagnetization of electromagnet dead electricity, voussoir is withstood on guide rail under the effect of spring, because slope angle is less than the friction angle that voussoir 3 and guide rail 2 produce, thereby forming larger surface friction drag formation self-locking makes voussoir stop sliding, and due to the slope angle design of voussoir, slide block can not get over voussoir to be continued to slide, slide block is understood and is stopped slip after power-off.
The present invention can realize emergency braking in the situation that of power-off, has improved operational security, and the present invention is simple in structure, and cost is lower.
