[0028] The utility model is described in detail below.

[0029] like Figures 1 - 3 As shown;

[0030] A car door of a construction elevator, which is slidably matched with an elevator car 10 and is used for opening and closing the elevator car 10, comprises a car door 1 which is lifted and lowered along the Z-axis direction and slidably matched with the elevator car 10, a flap 2 which is arranged below the car door 1 and is hinged to the elevator car 10, and a driving mechanism 3 which is transmission-connected to the flap 2;

[0031] When the elevator car 10 is closed, the car door 1 and the flap 2 will form a closed door opening facing the elevator car 10 .

[0032] When the elevator car 10 is opened, the car door 1 can be driven to move upward along the Z-axis manually or automatically. The flap 2 is controlled by the driving mechanism 3 to rotate around its hinge with the car door 1 to the side away from the elevator car 10, so that the entrance and exit of the elevator car 10 is opened. When the bottom surface of the flap 2 acts on the main structure, the entire entrance and exit of the elevator car 10 will be fully opened. At this time, construction personnel and equipment can pass through;

[0033] Through the automatic control of the flap 2, manual operation is not required, reducing the probability of safety accidents;

[0034] In some possible embodiments, the flap 2 includes a main board 21 hinged to the elevator car 10, and handrails 22 symmetrically arranged in the X-axis direction and mounted on the main board 21; a passage is formed between the two groups of handrails 22;

[0035] When the flap 2 is horizontally arranged under the drive of the driving mechanism 3 and closes the gap between the elevator car 10 and the main structure, the passage will communicate with the elevator car 10.

[0036] The setting of the handrails 22 will effectively create an unclosed area between the upper space of the flap 2 and the elevator car 10 after the elevator car 10 is opened;

[0037] Preferably, the height of the handrails 22 is 1.1m - 1.2m.

[0038] In some possible embodiments, in order to avoid hard contact between the bottom of the flap 2 and the main structure and damage to the main body after long-term use;

[0039] A buffer strip 23 is further provided at the bottom of the main board 21.

[0040] In some possible embodiments, in order to effectively control the rotation of the flap 2 through the driving mechanism 3, so as to cooperate with the car door 1 to realize the opening and closing of the entrance and exit of the elevator car 10;

[0041] The driving mechanism 3 includes a transmission shaft 31 arranged along the Y-axis direction and located at the bottom of the elevator car 10, a main gear 32 mounted on the transmission shaft 31, a slave gear 33 mounted on the flap 2 and meshing with the main gear 32, and a driving motor for controlling the transmission shaft 31 to rotate around its axis and mounted at the bottom of the elevator car 10.

[0042] When the entrance and exit is opened, the driving motor controls the transmission shaft 31 to rotate clockwise, thereby driving the main gear 32 to rotate clockwise. Since the slave gear 33 meshes with the main gear 32, the slave gear 33 rotates counterclockwise, thereby driving the main board 21 mounting the slave gear 33 to rotate counterclockwise and move to the side away from the elevator car 10; cooperating with the upward-sliding car door 1 to realize the opening of the entrance and exit.

[0043] The main gears 32 are in two groups, arranged at both ends of the transmission shaft 31 and coaxially with the transmission shaft 31. The secondary gears 33 are also in two groups, arranged on both sides of the main board 21 and arranged in one-to-one correspondence with the two groups of main gears 32. Specifically, each group of secondary gears 33 is arranged above the corresponding main gear 32.

[0044] In some possible implementation manners, in order to effectively enable the driving mechanism 3 to control the rotation of the flap 2 while effectively realizing the control of the car door 1 to slide along the Z-axis direction, a set of driving mechanism 3 is used to realize the synchronous movement of the flap 2 and the car door 1 to open and close the entrance and exit.

[0045] The driving mechanism 3 is in transmission cooperation with the car door 1 and is used to control the lifting of the car door 1 along the Z-axis direction.

[0046] The driving mechanism 3 further includes a driving gear sleeved on the transmission shaft 31, a driven gear installed outside the elevator car 10 and on the same side as the driving gear, and a chain that is in transmission cooperation with the driving gear and the driven gear and is connected to the car door 1.

[0047] The driving gear is sleeved on the transmission shaft 31 and fixedly connected to the transmission shaft 31, and the two are coaxially arranged. The driven gear is installed on the elevator car 10 and on the same side as the driving gear. The driven gear is located above the driving gear, and the two are connected by a chain. The chain also connects the car door 1.

[0048] Specifically, when the transmission shaft 31 rotates clockwise driven by the driving motor, it will drive the driving gear to rotate clockwise, thereby causing the chain to rotate and making the connection point between the chain and the car door 1 move upward, thereby realizing driving the entire car door 1 to move upward. When the flap 2 moves towards the side close to the main structure, the car door 1 moves upward to open the entire entrance and exit.

[0049] There are two groups of driving gears, and the driven gears and chains are arranged in one-to-one correspondence with the driving gears, making the lifting of the car door 1 more stable.

[0050] In some possible implementation manners, in order to effectively guide the lifting of the car door 1;

[0051] On the elevator car 10, a chute is arranged along the Z-axis direction, and on the car door 1, a slide rail that is slidably matched with the chute is arranged.

[0052] In some possible implementation manners, a first convex strip is arranged at the bottom of the car door 1, and the inner side surface of the first convex strip is coplanar with the inner side surface of the car door 1. At one end of the flap 2 away from the car door 1, a second convex strip 24 is arranged, and the outer side surface of the second convex strip 24 is coplanar with the outer side surface of the flap 2. The heights of the first convex strip and the second convex strip 24 are equal;

[0053] When the elevator car 10 is closed, the adjacent sides of the first rib and the second rib 24 are coplanar.

[0054] A construction hoist includes a guide rail frame arranged along the Z-axis direction and connected to the main structure, an elevator car 10 installed on the guide rail frame and slidingly engaged with the guide rail frame along the Z-axis direction, and a car door for opening and closing the entrance and exit of the elevator car 10 as described above.

[0055] The present utility model is not limited to the foregoing specific embodiments. The present utility model extends to any new feature or any new combination disclosed in this specification, as well as any new method or process step or any new combination disclosed.
