Detailed Description
Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. For the sake of clarity and brevity, actual embodiments are not limited to the features described in this specification. It will be appreciated that in the development of any such actual embodiment, as in any specific implementation, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. The present embodiment is implemented on the premise of the technical solution of the present invention, and detailed embodiments and processes are given, but the scope of the present invention includes, but is not limited to, the following embodiments.
Fig. 1 shows a schematic structural diagram of a turnover-type compensating chain guide according to an embodiment of the present invention. The turning type compensating chain guide is installed between counterweight guide rails 2 of a pit to guide a compensating chain 1. Typically, the compensating chain 1 is connected at one end to the counterweight assembly 3 and at the other end to the elevator car. As shown in fig. 1, the compensating chain guide according to the embodiment of the present invention includes a plurality of first arms 41, and the plurality of first arms 41 constitute a closed region so that the compensating chain 1 passes through the closed region. According to a preferred embodiment of the present invention, as shown in fig. 1, the compensating chain guide may comprise 4 first arms 41, the 4 first arms 41 being sequentially connected end to form a closed area that may enclose the compensating chain 1. According to another preferred embodiment, the first arms 41 may be coupled to each other by means of a bracket 42. According to a further preferred embodiment, the first arm 41 may take various shapes, such as a hyperboloid shape as shown in fig. 1, and may further take a cylindrical shape, a rectangular parallelepiped shape, or the like as deemed appropriate by those skilled in the art.
Furthermore, the compensating chain guide according to an embodiment of the present invention further includes a second arm 43, the second arm 43 being disposed in parallel with one of the plurality of first arms 41 and coupled thereto by a bracket 42. In the embodiment of the present invention, the upper surface of the second arm 43 is higher than the highest point of the upper surface of the first arm 41, and this is set to fundamentally avoid the counterweight 3 colliding with the first arm 41 of the compensating chain guide when moving downward. Because when the counterweight assembly 3 is moving downwards, it can only collide with the second arm 43, and not the first arm 41, even if it collides with the compensating chain guide. According to the preferred embodiment of the present invention, since the second arm 43 acts as a collision arm, it is preferably made of a material having a buffering action, so that there is a buffering action when the counterweight assembly 3 collides with this second arm 43, without a rigid collision having a destructive force.
According to a preferred embodiment of the present invention, the plurality of first arms 41 and the second arms 43 constitute a guiding assembly, as shown in fig. 3, which is fixed on the beam 5 across between the two counterweight guide rails 2 by a fixing bracket 47. Specifically, as shown in fig. 1, the guide assembly is coupled to the fixing bracket 47 through a connecting bracket 45 and a rotating shaft 44, wherein the connecting bracket 45 and the fixing bracket 47 are provided with through holes for the rotating shaft 44 to pass through.
Fig. 2 is a partially enlarged view of a connection portion of the connection bracket 45 and the fixing bracket 47 in fig. 1. As shown in fig. 2, a torsion device 46 is provided on the rotating shaft 44, and the torsion device 46 is located between the connecting bracket 45 and the fixing bracket 47. According to a preferred embodiment, the torsion device 46 may be a torsion spring that is sleeved on the rotating shaft 44. According to another preferred embodiment, a plurality of torsion force adjusting holes 451 may be provided on the connecting bracket 45 for adjusting the initial torsion force of the torsion spring 46 such that the guide assembly is in a substantially horizontal position in a normal state.
Further, as shown in fig. 1 and 2, the fixing bracket 47 of the compensating chain guide preferably includes a vertical wall 471, a blocking plate 472 perpendicular to the vertical wall 471 at an upper portion of the vertical wall 471, and a base 473 perpendicular to the vertical wall 471 at a lower portion of the vertical wall 471, wherein the blocking plate 472 serves to prevent the guide assembly from being deviated upward from a horizontal position.
Next, the specific action of the turnover type compensating chain guide 4 according to the embodiment of the present invention during the movement of the elevator will be specifically described with reference to fig. 3 to 5.
Fig. 3 is a schematic structural application diagram of the compensating chain guide device according to the embodiment of the present invention in a horizontal position in a normal state. That is, in a normal state, when the counterweight assembly 3 is not lowered to a height where it contacts the compensating chain guide, the compensating chain guide according to the present invention is substantially in a horizontal position as shown in fig. 3.
And once the counterweight assembly 3 moves downwards to collide with the compensating chain guide device, the counterweight assembly 3 first collides with the second arm 43 of the compensating chain guide device, which serves as a collision arm, and then overcomes the torsional force of the torsion spring 46 to make the guide assembly rotate around the rotating shaft 44 at the center of the torsion spring along with the downward movement of the counterweight assembly 3, and fig. 4 shows the structural application schematic diagram of the compensating chain guide device according to the embodiment of the present invention, which is collided to an angle in the collision process.
Thereafter, with further downward movement of the counterweight assembly 3, the guide assembly further rotates about the rotating shaft 44 of the torsion spring 46, thereby finally reaching a state in which the compensating chain guide is collided with a vertical condition during the collision as shown in fig. 5.
Thereafter, when the elevator starts to resume normal operation and the counterweight assembly 3 starts to move upwards to gradually disengage from the counterweight buffer, the guide assembly can be restored to the initial horizontal state as shown in fig. 3 by the torsional force of the torsion spring.
It can be seen from the actions of the above compensation chain guide device in the actual working process that the compensation chain guide device according to the present embodiment is a guide device that can be turned over correspondingly with the up-and-down movement of the counterweight assembly 3, so that the counterweight assembly 3 can be prevented from rigidly colliding with the compensation chain guide device, especially the first arm 41 thereof, thereby effectively avoiding the damage caused by rigid collision between the counterweight assembly 3 and the compensation chain guide device, and greatly improving the safety of the elevator.
According to another preferred embodiment of the invention, an elevator is also presented, which uses a compensating chain guide as shown in fig. 1-5. Since the core components and structure thereof have been described in detail above, they are not described in detail herein.
Although the present invention has been described in detail based on the preferred embodiments, those skilled in the art should understand that the claimed invention is not limited to the preferred embodiments. Without departing from the spirit and substance of the invention, a person skilled in the art, on understanding the present invention, is capable of carrying out numerous changes and modifications to the embodiments and therefore falling within the scope of the invention as defined by the appended claims.
