Background technology

Building hoist is the commonly used electromechanical equipment of current building trade, and holdback is the core in elevator Component, traditional lock device driving form uses the structure of more voussoirs mainly by Worm Wheel System form, however worm gear snail That there are efficiency is low for bar transmission, while the problem of transmission stability difference, causes service using life shorter, more wedge structure complexity can It is not high by property.Therefore there is an urgent need for the building construction hoist holdbacks that a kind of stationarity is good and reliability is high.

Utility model content

In view of the above-mentioned problems, technical solution provided by the utility model is a kind of two-way check of building construction hoist Device.

Specific technical solution is realized as follows：A kind of building construction hoist Bidirectional non-return device includes driven inner ring, master Dynamic inner ring, bearing, flange shell, check ring, outer shroud, key, voussoir and spring, the driven inner ring and active inner ring press gap Opposite direction fitting, the driven inner ring and active inner ring are separately mounted to by bearing in flange shell, wherein driven It is inside located on the left of active inner ring, the check ring includes circlip for hole and circlip for shaft, and two side bearings are logical It crosses circlip for hole and circlip for shaft is positioned, and be equipped with outer shroud, the outer shroud and flange shell between two bearings Inner wall is by key connection, and the voussoir is mounted in driven inner ring and the corresponding gap of active inner ring, and the inside of driven inner ring It is provided with notch of the same size with the side of voussoir, and notch is corresponding, the spring of precompression is installed between two notches.

Preferably, it is provided with hole on the flange shell.

Preferably, the voussoir section is trapezoidal.

Preferably, the spring is volute spring.

The building construction hoist Bidirectional non-return device of the utility model, normal work when two between centers power forward directions can be made to transmit Make, and check can be realized when power anti-pass is dynamic, it is simple in structure, improve the stability and reliability of equipment.

Description of the drawings

Fig. 1 is the overall structure diagram of the utility model embodiment.

Fig. 2 is that the right side of the utility model embodiment regards schematic diagram.

Label in attached drawing be：The driven inner ring of 1-, 2- active inner ring, 3- bearings, 4- flange shells, 5- check rings, 6- Outer shroud, 7- keys, 8- voussoirs, 9- springs, 51- circlip for holes, 52- circlip for shaft.

Specific implementation mode

The preferred technical solution of the utility model is described further with reference to the accompanying drawings and examples.

Embodiment is shown in shown in Fig. 1~2：A kind of building construction hoist Bidirectional non-return device includes driven inner ring 1, main Dynamic inner ring 2, bearing 3, flange shell 4, check ring 5, outer shroud 6, key 7, voussoir 8 and spring 9, the driven inner ring 1 and active For inner ring 2 by the opposite direction fitting of gap, the driven inner ring 1 and active inner ring 2 are separately mounted to flange shell by bearing 3 In body 4, wherein driven inner ring 1 is set to 2 left side of active inner ring, the check ring 5 includes circlip for hole 51 and axis bullet Property baffle ring 52, two side bearings 3 are positioned by circlip for hole 51 and circlip for shaft 52, and between two bearings 3 Equipped with outer shroud 6, the outer shroud 6 is connect with 4 inner wall of flange shell by key 7, and the voussoir 8 is mounted on driven inner ring 1 and active In 2 corresponding gap of inner ring, and the inside of driven inner ring 1 and the side of voussoir 8 are provided with notch of the same size, and notch is opposite It answers, the spring 9 of precompression is installed between two notches.

Preferably, it is provided with hole on the flange shell 4.

Preferably, 8 section of the voussoir is trapezoidal.

Preferably, the spring 9 is volute spring.

Specifically, driven inner ring 1 inputs axis connection by rectangular spline and elevator speed reducer, and active inner ring 2 passes through flat Key is connect with machine shaft, and when normal work, motor drives active inner ring 2 to be rotated, and is then driven in driven by voussoir 8 Ring 1 rotates, and power forward direction is passed to elevator speed reducer, elevator is in normal operating conditions at this time.When elevator stops The moment restarted afterwards, due to the effect of elevator dead weight, power is inversely transmitted to input terminal by lifting decelerator output end, and It is transmitted to driven inner ring 1, at this time since spring 9 carries precompression, spring 9 withstands the wedge positioned at driven inner ring 1 and active inner ring 2 Block 8 so that the 1 not reversible rotation of driven inner ring can be effectively prevented from building hoist and start moment downslide, improve equipment Reliability, while reverse load when reducing electric motor starting extends the service life of motor.

Preferred embodiments of the present invention above described embodiment only expresses, the description thereof is more specific and detailed, But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field For technical staff, without departing from the inventive concept of the premise, several deformations can also be made, improves and substitutes, these are all Belong to the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
