Detailed Description

The present invention will be further explained by the following embodiments with reference to the attached drawings.

Example 1: as shown in fig. 1 and 2, the general cage door for the construction elevator comprises a cage door body I1, a cage door body II 2 which is movably arranged on the cage door body I1 and moves along the width direction of the cage door body I1, and a driving mechanism 3 which drives the cage door body II 2 to move, wherein the cage door body II 2 is driven to move by the driving mechanism 3, so that the width of the cage door is changed, the cage door is universal, and the general cage door can be suitable for door openings with various widths.

In order to realize that the cage door body II 2 moves on the cage door body I1, two guide rail groups which are arranged up and down are arranged on the back surface of the cage door body I1, the two guide rail groups are close to the lower side and the upper side of the cage door body I1 as much as possible, each guide rail group at least comprises one guide rail 41, and the guide direction of each guide rail 41 is parallel to the width direction of the cage door body I1; two roller groups which are respectively limited on the two guide rail groups are arranged on the surface of the second cage door body 2 facing the back surface of the first cage door body 1, and each roller group comprises a plurality of rollers 42. With this structure, the roller 42 rolls on the guide rail 41 to move the second door 2, so that the second door 2 moves more smoothly. The two ends of the guide rail 41 are further provided with a limiting block 43 for limiting the moving position of the roller 42. In order to further improve the stability of the movement of the second door body 2 on the first door body 1, the guide rail set comprises two guide rails 41, and a plurality of rollers 42 in the roller set are arranged on two sides of the two guide rails 41.

In this embodiment, the driving mechanism 3 is a screw rod structure, is disposed in a space between the upper and lower guide rail sets, and includes a screw rod seat 31 disposed on the back of the door body 1, a screw rod 32 and a guide rod 33 disposed on the screw rod seat 31, and a moving stage 34 engaged with the screw rod 32 through a screw rod nut, wherein the guide rod 33 passes through the moving stage 34, and the moving stage 34 is connected with the door body 2 through a push-pull rod 35. The screw rod structure is used as a driving mechanism, the basic function of driving is realized, and meanwhile, the effect of locking along with stopping is achieved, namely after the screw rod structure stops acting, the second cage door body 2 is locked, so that the width of the cage door is convenient to adjust.

Just because the existence of lead screw structure, can lead to the focus of the whole cage door body 1 to be partial to the lead screw structure, at the lift in-process of whole cage door that hangs, this survey that the cage door body 1 is close to the lead screw structure is worn and torn comparatively badly, for this reason, the cage door body 1, its one side of keeping away from the lead screw structure is provided with weight balancing piece 5, and weight balancing piece 5 accessible is experimental to be set for, and under weight balancing piece 5's effect, the wearing and tearing of the cage door body 1 alleviate, have promoted the life-span of whole cage door that hangs.

In addition, a space A is inevitably formed between the cage door body II 2 and the cage door body I1, potential safety hazards exist due to the existence of the space A, for example, soft building materials such as ropes easily enter a gap between the cage door body II 2 and the cage door body I1 from the space A, for this purpose, a mounting strip 6 vertically extending from the top surface to the bottom surface of the cage door body II 2 is arranged on one side, away from the screw rod structure, of the cage door body II 2, the mounting strip 6 is provided with a partition plate mounting surface 61 which is flush with the front surface of the cage door body I1, the partition plate mounting surface 61 is used for mounting a partition plate, after the width of the cage door is adjusted, the partition plate is connected with the front surface of the cage door body I1, and the partition plate plays a role in blocking the space A.

As shown in fig. 3, the door opening and closing mechanism further includes an operating mechanism for operating the screw rod structure, the operating mechanism includes an operating rod 71 penetrating through the door opening and closing body 1 from the back of the door opening and closing body 1, and a transmission connecting structure 72 connecting the operating rod 71 and the screw rod 32, for the installation of the operating rod 71, an operating rod mounting seat 73 may be disposed on the screw rod seat 31, both ends of the operating rod 71 are rotatably disposed on the operating rod mounting seat 73 and the door opening and closing body 1, the transmission connecting structure 72 may employ a bevel gear transmission mechanism, the bevel gear transmission mechanism includes a first bevel gear and a second bevel gear which are respectively disposed on the screw rod 32 and the operating rod 71 and are engaged with each other, the transmission connecting structure 72 may also employ a worm gear mechanism, which is not illustrated in the worm gear mechanism diagram, and the worm gear mechanism includes a worm gear disposed on the screw rod 32 and a worm connected to the operating rod 71. The screw rod structure can act by rotating the control rod 71 in the control mechanism, so that the position of the cage door body II 2 can be adjusted, and the worker can directly adjust the interior of the cage again without detaching the whole cage door and then adjusting again if the worker finds that the width of the cage door is not right or the width deviation is large after the worker installs the cage because the control rod 71 penetrates through the cage door body I1 from the back of the cage door body I1. In order to prevent the operating rod 71 from being rotated by mistake during normal use of the elevator, the length of the operating rod 71 extending out of the door body 1 should be as small as possible, for example, the extending length of the operating rod 71 may be 5-10mm.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by the technical solution of the present invention by those skilled in the art should fall into the protection scope of the present invention, and the technical contents claimed by the present invention have been fully recorded in the claims.
