Description

[0002] At construction sites, construction materials often need to be transported by construction elevators or elevators. Construction materials are usually transported by transport carts.

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0028] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] refer to Figure 1-Figure 3 , shows a linkage type construction elevator anti-collision device, including a car 1, an upper elevator door 2 and a lower elevator door 3 that open and close up and down, characterized in that it also includes a first anti-collision beam 41, a first pull rope 42, and a first main pulley 43. One end of the first anti-collision beam 41 is fixed to the side wall of the car 1 through a hinge, and the first anti-collision beam 41 can rotate up and down around the hinge. The first main pulley 43 is arranged at the upper end of the side wall of the car 1, and the lower elevator door 3 is connected to the first pull rope 42. The first pull rope 42 is connected to the first anti-collision beam 41 after passing through the first main pulley 43.
[0030] When the elevator door is open, the upper elevator door 2 and the lower elevator door 3 are in the most distant state. Since the length of the first pull rope 42 is limited, when the lower elevator door 3 is at the lowest end of the open state, the first pull rope 42 will pull up the first anti-collision beam 41. The preferred solution is that the first anti-collision beam 41 is finally in a nearly vertical state, which does not affect the entry and exit of the transport trolley. When the transport trolley enters the elevator and stops, the elevator door is closed, and the lower elevator door 3 moves upward. The first pull rope 42 releases the tension on the first anti-collision beam 41. After the nearly vertical first anti-collision beam 41 loses its tension, it will rotate downward due to gravity. The first pull rope 42 moves simultaneously with the elevator door, and the first anti-collision beam 41 moves with the first pull rope 42. During the entire process of lowering the first anti-collision beam 41, the speed can be controlled to be smooth and safe. When the elevator door is completely closed, the preferred state is that the first anti-collision beam 41 is just in a horizontal state. The transport trolley usually enters the elevator door directly, so the wheels of the transport trolley also move in the front-to-back direction. When the first anti-collision beam 41 is lowered, it can protect against collisions in the front-to-back direction.
[0031] In some specific embodiments, a first secondary pulley 44 is further included, and the first secondary pulley 44 is arranged below the first main pulley 43 and on the side wall of the car 1 above the lower elevator door 3. The first pull rope 42 passes through the first main pulley 43 and the first secondary pulley 44 from the lower elevator door 3 and is connected to the first anti-collision beam 41. The first secondary pulley 44 is provided to arrange the routing of the first pull rope 42 in the elevator, to prevent the first pull rope 42 from occupying too much main activity space in the elevator, and to limit the first pull rope 42 to a side position.
[0032] In some specific embodiments, the second anti-collision beam 51, the second pull rope 52, and the second main pulley 53 are further included. The second anti-collision beam 51 is arranged on the inner side of the car 1 parallel to the first anti-collision beam 41. One end of the second anti-collision beam 51 is fixed to the side wall of the car 1 by a hinge. The second anti-collision beam 51 can rotate up and down around the hinge. The second main pulley 53 is arranged on the side wall of the car 1 higher than the lower elevator door 3. The lower elevator door 3 is connected to the second pull rope 52. The second pull rope 52 is connected to the second anti-collision beam 51 after passing through the second main pulley 53. The functions of the second anti-collision beam 51, the second pull rope 52, and the second main pulley 53 are similar to those of the first anti-collision beam 41, the first pull rope 42, and the first main pulley 43, which is equivalent to adding an additional anti-collision beam on the inner side, so that the front and rear directions of the transport trolley are both protected from collision. The combination and function of the second anti-collision beam 51, the second pull rope 52, and the second main pulley 53 are similar to the aforementioned implementation method of the second anti-collision beam 51 combination, and will not be repeated here.
[0033] In some specific embodiments, a second secondary pulley 54 is further included, and the second secondary pulley 54 is arranged below the second main pulley 53 and on the side wall of the car 1 above the lower elevator door 3. The second pull rope 52 passes through the second main pulley 53 and the second secondary pulley 54 from the lower elevator door 3 in sequence and is connected to the second anti-collision beam 51. The second secondary pulley 54 is provided to arrange the routing of the second pull rope 52 in the elevator, to prevent the second pull rope 52 from occupying too much main activity space in the elevator, and to limit the second pull rope 52 to a side position.
[0034] In some specific embodiments, the other end of the first anti-collision beam 41 and the second anti-collision beam 51 away from the hinge is provided with a limiting and stabilizing member 6, which is fixed on the side wall of the elevator car 1. When the elevator door is closed, the first anti-collision beam 41 and the second anti-collision beam 51 can fall on the limiting and stabilizing member 6. The limiting and stabilizing member 6 is preferably welded to the side wall of the car 1 to reinforce the anti-collision beam. Because fixing the anti-collision beam only by a hinge may not prevent a relatively strong impact, the setting of the limiting and stabilizing member 6 can disperse the pressure and resist a relatively strong impact.
[0035] In some specific implementations, the elevator position limiting and stabilizing member 6 is in a "U" shape, and when the elevator door is closed, the first anti-collision beam 41 and the second anti-collision beam 51 can fall into the grooves of their respective elevator position limiting and stabilizing members 6.
[0036] In some specific embodiments, at least one of the first anti-collision beam 41 and the second anti-collision beam 51 is installed with a buffer device. By providing a buffer device, instantaneous pressure can be dispersed to resist impacts of greater intensity. The buffer device is preferably a plurality of springs, one end of which is installed on the first anti-collision beam 41 and / or the second anti-collision beam 51, and the other end is arranged toward the space where the transport trolley is located. An impact plate can be welded to the end of the plurality of springs facing the transport trolley to withstand the impact force. After the impact plate receives the impact, the pressure will be evenly dispersed to each spring, and then transmitted to the anti-collision beam by each spring. In other embodiments, the buffer device can also be replaced by sponge, rubber, cotton, etc.
[0037] In some specific embodiments, the displacement length of the connection point between the first pull rope 42 and the lower elevator door 3 moving downward is A; when the elevator door is closed, the distance between the connection point between the first pull rope 42 and the first anti-collision beam 41 and the first main pulley 43 is B, and the displacement length A is less than the distance B. In order to ensure that the first pull rope 42 does not pull the anti-collision beam into the first main pulley 43, it is necessary to ensure that the distance B is long enough. As long as the distance B is greater than the displacement length of the connection point between the lower elevator door 3 moving downward, it can be ensured that when the first anti-collision beam 41 rotates, the first pull rope 42 will not be broken due to insufficient length or other damage will be caused.
[0038] In some specific embodiments, the displacement length of the connection point between the second pull rope 52 and the lower elevator door 3 moving downward is C; when the elevator door is closed, the distance between the connection point between the second pull rope 52 and the second anti-collision beam 51 and the second main pulley 53 is D, and the displacement length C is less than the distance D. The reason for this setting is the same as that for A and B, and will not be repeated here.
[0039] The present application further provides a linkage type construction elevator anti-collision device, which is mainly suitable for elevator doors that open and close left and right, including a car 1, an elevator door that opens and closes left and right, and also includes a third anti-collision beam, a third pull rope, and a third main pulley. One end of the third anti-collision beam is fixed to the side wall of the car 1 through a hinge, and the third anti-collision beam can rotate up and down around the hinge. The third main pulley is arranged on the side wall of the car 1 on the same side as the hinge and higher than the hinge position. The elevator door on the same side as the hinge is connected to the third pull rope, and the third pull rope is connected to the third anti-collision beam after passing through the third main pulley;
[0040] It also includes a fourth anti-collision beam, a fourth pull rope, and a fourth main pulley. The fourth anti-collision beam is arranged on the inner side of the car 1 parallel to the third anti-collision beam. One end of the fourth anti-collision beam is fixed to the side wall of the car 1 through a hinge. The fourth anti-collision beam can rotate up and down around the hinge. The fourth main pulley is arranged on the side wall of the car 1 on the same side as the hinge and higher than the hinge position. The elevator door on the same side as the hinge is connected to the fourth pull rope, and the fourth pull rope is connected to the fourth anti-collision beam after passing through the fourth main pulley.
[0041] The principle of anti-collision for elevator doors that open and close left and right is that when the elevator door is open, the left and right elevator doors are in the most distant state. Since the length of the third pull rope is limited, when the left elevator door is at the leftmost end of the open state, the third pull rope will loosen the third anti-collision beam, and the third anti-collision beam will be in a state close to natural drooping, which does not affect the entry and exit of the transport vehicle. When the transport vehicle enters the elevator and stops, the elevator door is closed, and the left elevator door moves to the right. The third pull rope applies tension to the third anti-collision beam, gradually pulling up the third anti-collision beam that is close to natural drooping. When the elevator door is completely closed, the optimal state is that the third anti-collision beam is just in a horizontal state. The principle of the fourth anti-collision beam combination is similar to that of the third anti-collision beam combination, and will not be repeated here. The third and fourth anti-collision beams can protect against collisions in the front and rear directions of the transport vehicle.
[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
