Description

Technical Field

[0001] The utility model relates to the technical field of protective devices, in particular to a wellhead protective device for elevator engineering. Background Art

[0002] The elevator shaft is the hoistway where the elevator is installed. The elevator track and counterweight track are installed on the shaft wall. The elevator door is installed in the reserved door opening. There is an elevator machine room on the top of the shaft. Before the elevator is installed, in order to avoid the occurrence of safety accidents, it is necessary to set a protective device at the elevator shaft opening. An existing patent is a horizontal protective device for a construction engineering elevator shaft. The patent announcement number CN214886059U includes an inner rod and a clamping plate. Sleeve rods are movably sleeved on both sides of the inner rod. A clamping seat is installed on the outside of the sleeve rod. The front end of the clamping seat is rotated to insert a bolt, a movable block is installed at the end of the bolt, and a movable seat is installed at the front end of the clamping plate. The utility model can adjust the length by extending and retracting the sleeve rod on both sides of the inner rod. After adjusting to the appropriate length, the clamping seat can be clamped on both sides of the elevator shaft opening, and then the bolt is rotated. At this time, the movable block at the end of the bolt can be located in the movable hole and rotated, and the bolt can drive the clamping plate to move. At this time, the clamping plate can cooperate with the clamping seat to complete the clamping and fixing work, thereby completing the installation of the equipment. After installation, it can play a protective effect. This device can be suitable for shaft openings of different sizes, and there is no need to use bolts and other structures. It can quickly complete disassembly and assembly, is more practical, and is suitable for wide promotion and use.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: although effective protection of the elevator shaft opening can be achieved, in the actual protection process, when children become curious about the elevator shaft opening, or toys and other items fall into the shaft, they will lie on the sleeve rod and the inner rod to look inside the elevator shaft opening. Since it is difficult for children to control their center of gravity, it is very easy for children to climb over the device and fall into the shaft. That is, the technical solution proposed by the above-mentioned patent technology has the defect of poor protection performance.

[0004] Therefore, we proposed a shaft protection device for elevator engineering to solve the above problems. Utility Model Content

[0029] See also Figure 1-4 The utility model provides a technical solution: a shaft protection device for elevator engineering, comprising:

[0030] The moving assembly 100 includes a U-shaped moving frame 101 and four moving wheels 102 arranged on the lower surface of the U-shaped moving frame 101;

[0031] The protection component 200 includes a U-shaped protection frame 201 arranged above the U-shaped moving frame 101, the upper surface of the U-shaped moving frame 101 is provided with a U-shaped groove, the inner wall of the U-shaped groove is rotatably provided with a bidirectional lead screw 202, and the outer surface of the U-shaped moving frame 101 is provided with a rotating disk 203 for rotating the bidirectional lead screw 202, the inner wall of the U-shaped moving frame 101 is slidably provided with two symmetrical sliders 204, and the surfaces of the two sliders 204 are provided with threaded holes threadedly connected to the outer surface of the bidirectional lead screw 202, the upper surface of the slider 204 is rotatably provided with a push rod 205, and the top end of the push rod 205 is rotatably connected to the lower surface of the U-shaped protection frame 201.

[0032] The outer surfaces of both ends of the U-shaped moving frame 101 are provided with fixing components 300 for fixing the U-shaped moving frame 101 to the inner wall of the elevator door installation opening above the elevator shaft.

[0033] The fixing assembly 300 includes a fixing tube 301 symmetrically fixed on the outer surfaces of both ends of the U-shaped moving frame 101, and a telescopic column 302 slidably arranged on the inner wall of the fixing tube 301, and a connecting plate is fixed to the end of the telescopic column 302. The outer surface of the fixing tube 301 is threadedly connected with a locking bolt 303 extending into the interior of the fixing tube 301 for locking the telescopic column 302.

[0034] By providing the protection component 200 and the fixing component 300, the device can be pushed to the position of the elevator shaft opening during actual use, and then the telescopic column 302 can be pulled outward and connected to the inner walls of the two sides of the elevator door, and then locked by the locking bolts 303, and then the rotating disk 203 is rotated. The rotation of the rotating disk 203 drives the two-way screw 202 to rotate, and the rotation of the two-way screw 202 drives the two sliders 204 to move to both sides at the same time, thereby driving the two push rods 205 to push the U-shaped protection frame 201 upward, so as to achieve the purpose of raising the U-shaped protection frame 201 for protection, so that when the personnel lie on the U-shaped protection frame 201 to observe the shaft opening, if it accidentally falls over, the personnel will fall on the ground inside the U-shaped moving frame 101, thereby improving the safety performance and effectively solving the defect of poor protection performance in the prior art.

The blocking plate 401 can be automatically extended to block the elevator shaft by rotating the rotating disk 203, and the setting of the load-bearing plate 405 effectively improves the stability of the blocking plate 401 when moving.

[0039] Among them, by setting up the blocking component 400, when the device realizes the process of raising the U-shaped protective frame 201 by rotating the rotating disk 203, the rotation of the bidirectional lead screw 202 can drive the threaded column 402 to rotate under the action of the two bevel gears 403. The rotation of the threaded column 402 drives the blocking plate 401 to extend outward under the action of the cylindrical thread groove 404, thereby blocking the elevator shaft opening, thereby further improving the safety performance of the protective device.

[0040] When working, after pushing it to the position of the elevator shaft, pull out the telescopic column 302 and make it connect to the inner walls of the two sides of the elevator door, and then lock it with the locking bolts 303, and then turn the rotating disk 203.
