Description

Technical Field

[0001] This utility model belongs to the technical field of building safety protection equipment, and more specifically, it relates to an elevator shaft clamp-type edge protection device. Background Technology

[0002] Elevator shaft edge protection devices are specialized safety protection equipment designed for elevator shaft openings during the construction phase. Their core function is to prevent construction personnel, tools, or materials from falling from the shaft opening, providing safety for high-altitude operations. The device typically consists of a rectangular protective door as the main body, using a square tube welded frame paired with a galvanized protective mesh or grid plate. The existing method of fixing elevator shaft edge protection doors is generally to drill holes at the elevator shaft opening and then use expansion bolts to fix the protective door.

[0003] Existing application number: CN202323493974.1. This utility model discloses a movable safety protection door for elevator shaft openings, belonging to the technical field of construction safety. It includes a safety door frame, a sheet metal safety warning sign, a sheet metal toe board, longitudinal uprights, transverse railings, and a fixed crossbar with movable door clips. Two movable door clips are provided on each side of the safety protection door. The movable door clips are installed on two adjacent transverse railings and adjacent civil engineering walls. The safety door frame and longitudinal uprights are welded from square tubing. The transverse railings are composed of several evenly distributed square tubings welded to the safety door frame and longitudinal uprights. A sheet metal safety warning sign is provided in the middle of the safety protection door and welded to the fixed crossbar. A sheet metal toe board is provided at the bottom of the safety protection door and welded to the fixed crossbar. This utility model uses movable door clips to fix the safety door without any tools, facilitating installation and disassembly during construction and improving work efficiency.

[0004] Based on the above, existing elevator shaft edge protection devices generally adopt the method of fixing by expansion bolts penetrating the wall. The locking nut needs to be exposed on the outside of the wall to complete the installation and fastening. In the complex working environment of building construction, construction workers are prone to disassembling the locking nut due to misoperation, temporary work needs, or irrelevant personnel touching it at will, which directly undermines the fixed reliability of the protection device and causes the edge protection function to fail. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an elevator shaft clamp-type edge protection device. This addresses the issue that existing elevator shaft edge protection devices commonly use expansion bolts to penetrate the wall for fixing, requiring the locking nut to be exposed outside the wall for installation and tightening. In complex construction environments, construction workers are prone to misoperation, temporary work requirements, or unauthorized personnel touching the locking nut, directly compromising the reliability of the protection device and causing the edge protection function to fail.

[0006] The purpose and effectiveness of this utility model's clamp-type edge protection device for elevator shafts are achieved through the following specific technical means: An elevator shaft clamp-type edge protection device includes a protective door body, a protective waist plate, a kick plate, a mounting drive box, a mounting locking handle, a touch warning mechanism, and a mounting locking mechanism. The protective waist plate is welded to the front center of the protective door body; the kick plate is welded to the front lower side of the protective door body; the mounting drive box is fixedly connected to the rear of the protective door body; the mounting locking handle is rotatably connected to the front center of the protective door body; the touch warning mechanism is located on the outside of the protective door body; and the mounting locking mechanism is located inside the mounting drive box.

[0007] Furthermore, the touch warning mechanism includes a vibration sensor and an alarm; the vibration sensor is fixedly connected to the lower rear side of the main body of the protective door; the alarm is an audible and visual alarm structure, and the vibration sensor is electrically connected to the control circuit of the alarm through a wire.

[0008] Furthermore, the mounting locking mechanism includes: a first mounting gear and a second mounting gear; the first mounting gear is rotatably connected inside the mounting drive box and coaxially fixedly connected to the rear end of the mounting locking handle; the second mounting gear is provided in two sets, the two sets of second mounting gears are rotatably connected inside the mounting drive box respectively, and the two sets of second mounting gears mesh with the left and right sides of the first mounting gear respectively.

[0010] Furthermore, the installation locking mechanism also includes a locking connecting ring and a locking limiting ring; the locking connecting ring is coaxially fixedly connected to the rear of the outer periphery of the installation locking handle; the locking limiting ring is fixedly connected to the front middle position of the protective door body, and the locking limiting ring is located on the outer periphery of the locking connecting ring.

[0011] Furthermore, the installation locking mechanism also includes: an opening / closing drive cam, a locking limit pin, a locking connecting spring, and an opening / closing insert; the opening / closing drive cam is rotatably connected to the inner side of the locking connecting ring; the locking limit pin is slidably connected to the inner side of the locking limit ring, and the right end of the locking limit pin is inserted into the inner side of the locking connecting ring; one end of the locking connecting spring is fixedly connected to the locking limit pin, and the other end of the locking connecting spring is fixedly connected to the locking limit ring; the opening / closing insert is inserted above the opening / closing drive cam.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a touch-sensitive warning mechanism to cause the protective door body to vibrate. At this time, a vibration sensor receives the vibration signal and converts it into an electrical signal to control the alarm to activate. The alarm then emits an audible and visual alarm, reminding workers to stay away from the protective door body, thus protecting the workers.

[0013] This utility model, through the installation and locking mechanism, places the protective door body in front of the elevator shaft opening. Rotating the installation and locking handle drives the first installation gear, which in turn drives the second installation gear, which in turn drives the installation adjusting screw. The installation adjusting screw then causes the installation transmission component to move in the opposite direction, which in turn causes the installation clamp to move in the opposite direction, locking it against the walls on both sides of the elevator shaft opening. Rotating the installation adjusting bolt causes the installation adjusting plate to move forward, thus clamping the installation adjusting plate against the wall and securing the entire protective door body, facilitating the installation and locking of the door. Installation and disassembly of the main body of the protective door: When it is necessary to disassemble the main body of the protective door, the safety officer first inserts the opening and closing plug into the opening and closing drive cam, rotates the opening and closing drive cam, and the opening and closing drive cam rotates outward to press the locking limit pin. The locking limit pin moves outward and is no longer inserted with the locking connecting ring. At this time, the locking connecting ring can rotate normally, and then the installation locking handle can be rotated to complete the disassembly operation. Only authorized safety officers can unlock the door through the matching opening and closing plug. Unauthorized personnel cannot rotate the installation locking handle to disassemble the door alone. From a mechanical structure perspective, the risk of accidental or unauthorized disassembly leading to the failure of the protection is eliminated, which improves the overall effectiveness and safety of the edge protection device.
