[0005] By setting the above structure, the operating block is rotated forward, and the threaded plate moving downward drives the four push plates to move away from each other through the four connecting rods. The four push plates moving away from each other drive the two plug rods to be inserted into the eight plug holes respectively. At this time, the protective shell blocks the top of the elevator shaft, making it difficult for the workers working on the top of the elevator shaft to fall into it. The operating block is reversed, and the eight plug rods are moved out of the plug holes and moved into the protective shell. At this time, the protective device can be disassembled, and the operation is simple.

[0006] As a preferred implementation manner, the groove is opened on the upper surface of the shell, and the operating block is arranged in the groove.

[0007] By providing the groove and the operating block, since the operating block is arranged in the groove, the upper surface of the operating block and the upper surface of the protective shell are in the same plane.

[0009] As a preferred implementation, the threaded plate and the four connecting rods are all arranged in a protective shell.

[0010] By providing a protective shell and a push plate, since the push plate is slidably connected in the protective shell, the protective shell can limit the push plate so that the push plate will not shake during movement, and the push plate can move smoothly in the protective shell under the push or pull of four connecting rods.

[0011] As a preferred implementation, the threaded rod is arranged between four push plates.

[0012] By arranging the threaded plate and the threaded rod, the rotating threaded rod can drive the threaded plate to move smoothly along the axial direction of the threaded rod.

[0013] As a preferred embodiment, the shape of the handle is set to be U-shaped, and the middle part of the handle is set to be arc-shaped and convex upward.

[0014] By providing the handles, the staff can conveniently move the device through the handles, and the rope can also be fixed to the arc-shaped portion between the two handles, so that the staff can pull the device to move in the elevator shaft through the rope and the handles.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model is provided with an operating component, a pushing component, a fixing component and a socket. The operating block is rotated forward, and the threaded plate moving downward drives four push plates to move away from each other through four connecting rods. The four push plates moving away from each other drive two plugging rods to be inserted into the eight plugging holes respectively. At this time, the protective shell shields the top of the elevator shaft, so that the workers working on the top of the elevator shaft are not easy to fall into it. The operating block is reversed, and the eight plugging rods are all moved out of the sockets and moved into the protective shell. At this time, the protective device can be disassembled, and the operation is simple.

[0017] The utility model is provided with a protective shell and a push plate. Since the push plate is slidably connected in the protective shell, the protective shell can limit the push plate so that the push plate does not shake during movement, and the push plate can move smoothly in the protective shell under the push or pull of four connecting rods.

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] See also Figure 1-3 The utility model provides an elevator shaft protection device, including a protection shell 1, an operating component 2, a pushing component 3 and four fixing components 4. The protection shell 1 includes a shell 11, a groove 12 and two handles 13. The upper surface of the protection shell 1 is connected to the two handles 13. The shape of the handle 13 is set to be U-shaped, and the middle part of the handle 13 is set to be arc-shaped and convex upward. By setting the handle 13, the staff can conveniently move the device through the handle 13, and the rope can also be fixed to the arc-shaped part between the two handles 13, so that the staff can pull the device through the rope and the handle 13 to move in the elevator shaft 6;

[0025] The operating assembly 2 includes two bearings 21, a threaded rod 22 and an operating block 23. The groove 12 is opened on the upper surface of the housing 11, and the operating block 23 is arranged in the groove 12. By setting the groove 12 and the operating block 23, since the operating block 23 is arranged in the groove 12, the upper surface of the operating block 23 and the upper surface of the protective shell 1 are in the same plane;

[0026] The two bearings 21 are both clamped in the housing 11, and the threaded rod 22 is clamped in the two bearings 21. By providing the bearings 21, the threaded rod 22 can be limited and fixed in the protective housing 1 under the action of the two bearings 21;

[0027] The top end of the threaded rod 22 is connected to the operating block 23. The pushing assembly 3 includes a threaded plate 31 and four connecting rods 32. The threaded plate 31 is threadedly connected to the outside of the threaded rod 22. By setting the threaded plate 31 and the threaded rod 22, the rotating threaded rod 22 can drive the threaded plate 31 to move smoothly along the axial direction of the threaded rod 22.

[0028] The threaded plate 31 is hinged to one end close to the four connecting rods 32 through four pins respectively. The threaded plate 31 and the four connecting rods 32 are all arranged in the protective shell 1. The fixing assembly 4 includes a push plate 41 and two plug rods 42. The sides of the four push plates 41 that are away from each other are connected to the two plug rods 42. The threaded rod 22 is arranged between the four push plates 41. The push plate 41 is slidably connected in the protective shell 1. By setting the protective shell 1 and the push plate 41, because the push plate 41 is slidably connected in the protective shell 1, the protective shell 1 can limit the push plate 41, so that the push plate 41 will not shake when moving, so that the push plate 41 can move smoothly in the protective shell 1 under the push or pull of the four connecting rods 32;

[0029] The adjacent sides of the four push plates 41 are hinged to the ends away from the four connecting rods 32 through pin shafts, the eight plug rods 42 are inserted into the sockets 5, the eight sockets 5 are opened in the elevator shaft 6, the protective shell 1 is arranged in the elevator shaft 6, and the plug rods 42 and the sockets 5 are arranged so that the protective shell 1 can be fixed in the elevator shaft 6.

[0030] The working principle and use process of the utility model are as follows: when the protective device needs to be used, the protective shell 1 is moved in the elevator shaft 6. When the protective shell 1 drives the eight insertion rods 42 to be aligned with the insertion holes 5, the external hexagonal wrench is inserted into the operating block 23 to align and rotate forward. The rotating operating block 23 drives the threaded rod 22 to rotate in the two bearings 21. The rotating threaded rod 22 drives the threaded plate 31 to move downward. The threaded plate 31 moving downward drives the four push plates 41 to move away from each other in the protective shell 1 through the four connecting rods 32. The four push plates 41 moving away from each other drive the two insertion rods 42 to be inserted into the eight insertion holes 5 respectively. At this time, the protective shell 1 blocks the top of the elevator shaft 6.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
