Abstract
The utility model discloses a wedge block guiding device of a pair of elevator lifting safety tongs. The utility model is characterized in that the pair of safety tongs is provided with a guide plate, the wedge block is arranged on the guide plate in a sliding mode, one end of an elastic element is connected with a fixing element on the pair of safety tongs, the other end of the elastic element is connected with a guiding pin roller component, the guiding pin roller component is used for guiding the movement of the wedge block of the pair of safety tongs and the guiding pin roller component is spaced through a spacing element. The utility model has the advantages of simple structure, reliable movement and easy realization and the utility model can make the movement of the wedge block of the pair of elevator lifting safety tongs steady and easy to reset.
Description
Technical field
The utility model relates to a kind of being used in and the up hypervelocity of lift car is implemented on the safety tongs of protection the guide piece that makes the safety tongs voussoir steadily move and to reset.
Background technology
The standard GB 7588-2003 of elevator industry requires elevator to set up the car protection device for over-speed ascending.Up safety tongs is as a kind of stopping device wherein, thus when the up hypervelocity of car its voussoir clamping guide rail stop car under the shift mechanism effect.The guiding of safety tongs voussoir and force transfer element are that roller should be in pincers seats top desired location and keep stabilized conditions, only up safety tongs action voussoir with just roll downwards after guide rail contacts with voussoir, make the stop process steady; Roller can scroll up and make voussoir be easy to separate when safety tongs resets, and roller also will be got back to original position simultaneously, and therefore up safety tongs needs the requirement that a guide piece keeps the position of deck end roller and realizes easy motion.
On the present safety tongs deck end roller is arranged, but its structure is difficult to meet the demands.Such as having plenty of descending safety tongs is inverted as up safety tongs use, but, can not be rolled downwards with voussoir because roller has been in the bottom because of conducting oneself with dignity, so the motion instability of voussoir; What have passes through to improve voussoir, the spacing roller that blocks, roller is moved downward and rolling relatively with voussoir, but because the existence of friction is difficult to guarantee the accurate position of roller, simultaneously since up safety tongs voussoir and pull bar thereof generally support with spring, roller has increased system weight with voussoir, and support spring rigidity is increased, and structurally is difficult to realize.
Summary of the invention
The purpose of this utility model is for a kind of a kind of guide piece that can make ascending for elevator safety tongs voussoir stable action and voussoir be easy to reset is provided, and this apparatus structure is simple, and reliable in action realizes easily.
Main technical schemes of the present utility model is: the guide plate that is mounted thereon for wedge slides is arranged on the safety tongs, and elastic element one end is connected with connecting element on the safety tongs, and the other end is connected with the deck end roller assembly that guides the safety tongs wedge block movement.The deck end roller assembly is sling by spring under the normal circumstances, by the limit element back-moving spring, make the deck end roller assembly keep stable, when the action voussoir of up safety tongs with after guide rail contacts, roll downwards because of pressure effect deck end roller assembly overcomes spring force, voussoir is along with the deck end roller assembly operating finishes to stroke, owing to be friction of rolling, therefore operate steadily, the stroke of deck end roller assembly motion is half of voussoir stroke.Because of the scrolling up of deck end roller assembly, voussoir separated with guide rail when voussoir resetted, and the deck end roller assembly is got back to the normal position under the effect of spring simultaneously.Tram when therefore this device can guarantee up safety tongs deck end roller assembly action and the true(-)running of deck end roller assembly and reset.
The utility model has following advantage with comparing of background technology: 1, simple in structure, do not need to change the structure of voussoir; 2, guarantee the tram of deck end roller assembly; 3, guarantee that the voussoir action is to roll along the deck end roller assembly surface to move, and impacts stable minimizing of stop; 4, do not increase the weight of voussoir and pull rod device.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 has safety tongs structural representation of the present utility model;
Fig. 2 a is the local structure scheme drawing of the normal condition of an embodiment of the utility model;
Fig. 2 b is the local structure scheme drawing of the operating state of Fig. 2 a illustrated embodiment.
The specific embodiment
Shown in Fig. 1,2a, the structure of the voussoir guide piece of this ascending for elevator safety tongs is: have on the safety tongs 8 for be slidingly installed thereon guide plate 3 of voussoir 5, elastic element 1 one ends are connected with connecting element on the safety tongs, and the other end is connected with the deck end roller assembly 2 of guiding safety tongs wedge block movement.Described elastic element 1 is a spring, and the connecting element on the described safety tongs is a guide plate 3, and each one of these guide plate 3 front and back are arranged on the side guide block 7, and voussoir 5 and can slide along guide plate between front and back guide plate 3.The installation direction of spring is consistent with the direction of wedge block movement.Deck end roller assembly 2 is provided with along the guide block 7 of resting guide 3, and between the voussoir back side and guide block 7.The stroke of deck end roller assembly motion is half of wedge block movement stroke.Spring 1, deck end roller assembly 2 and voussoir 5 are in normal condition when safety tongs does not move, spring 1 upper end links to each other with pin on the guide plate 3, the lower end deck end roller assembly 2 that plays, voussoir side guide 3 has limit element 6 to make spring 1 tension simultaneously, therefore deck end roller assembly 2 is in stabilized conditions, can up-down vibration, this moment, voussoir 5 did not contact with guide rail 4.Shown in Fig. 2 b, when safety tongs moves, voussoir 5 tensions move downward, near guide rail 4, when contacting with guide rail 4, the counter-force of guide rail 4 compresses the elastic element in deck end roller assembly 2, guide block 7 and the outside by voussoir simultaneously, therefore deck end roller assembly 2 overcomes the power of spring 1 along with voussoir 5 rolls along guide block 7 surfaces downwards, when stroke end of a period voussoir is blocked, this moment, the elastic element distortion in guide block 7 outsides was maximum, and it is maximum that the safety tongs braking force also reaches.Deck end roller assembly 2 rolls and guides voussoir 5 actions in loading process, make stable action, the descending stroke of deck end roller assembly is determined by the stroke of voussoir, therefore can guarantee the tram of force transfer element deck end roller assembly 2, make stressed even, when oppositely jiggering resetted safety tongs, deck end roller assembly 2 voussoir 5 that scrolls up unclamped with guide rail 4, and the deck end roller assembly is got back to initial position under the effect of spring 1.
