Description

Technical Field

[0001] The utility model relates to the field of safety protection equipment, in particular to a protection and stabilization device for safety engineering. Background Art

[0002] Safety engineering is an engineering field that takes various accidents occurring in human production and life activities as its main research object, and comprehensively applies relevant knowledge and achievements in natural sciences, technical sciences, and management sciences to identify and predict unsafe factors in production and life activities, and take effective control measures to prevent accidents or reduce accident losses. When carrying out construction projects, it is often necessary to use construction lifts to carry people and cargo.

[0003] After searching, a Chinese patent disclosed a safety protection device for construction elevators (publication number CN220618054 U). By setting an extension plate at the bottom of a traditional construction elevator, the gap problem between the elevator car and the floor plate can be solved by moving the extension plate when the construction elevator is docked with the floor.

[0004] Although the above application solves the problem of the gap between the elevator car and the floor plate, the extension plate and the car door need to be operated separately, which may easily lead to the situation that the extension plate is not extended in time. In addition, the extension plate is a horizontal extension, and the contact effect with the floor door is not good, and the stability is poor. Therefore, a protective stabilization device for safety engineering is proposed to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide a protective stabilizing device for safety engineering in order to solve the above problems, thereby improving the problem that workers step on empty space when going up and down the elevator because the extension plate is not extended in time.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a protective and stabilizing device for safety engineering, including an elevator car, wherein two second door shafts are rotatably connected in the elevator car and are symmetrically distributed, and an outer door panel is fixedly connected on the surface of the second door shaft, and a limiting groove is provided in the outer door panel, and a limiting frame is provided in the elevator car; a protective component, wherein the protective component is installed in the limiting groove; the protective component includes a driving motor embedded in the limiting groove, a threaded rod is fixedly connected to the output end of the driving motor, a driving block is provided outside the threaded rod, and four symmetrically distributed slide rails are provided in the limiting groove, and two symmetrically distributed sliders are slidably connected on the surface of each of the slide rails, a fixing plate is fixedly connected to the outside of the slider, and an inner door panel is fixedly connected on the surface of the fixing plate, and the top of the inner door panel extends into the limiting frame.

[0007] Preferably, four first door shafts are rotatably connected in the elevator car and are symmetrically distributed, and opening and closing door panels are fixedly connected to the surfaces of the first door shafts.

[0008] Preferably, the number of the opening and closing door panels is two and they are symmetrically distributed, and handles are fixedly connected to the surfaces of the two opening and closing door panels.

[0009] Preferably, a rotating motor is embedded in the elevator car, and the installed rotating motor drives the outer door panel to rotate. When the outer door panel touches the ground, the workers can go up and down the elevator through the outer door panel.

[0010] Preferably, there are two rotating motors and they are symmetrically distributed. The two rotating motors are respectively located on both sides of the outer door panel. The two symmetrical rotating motors will drive the outer door panel to flip, thereby turning the outer door panel into a pedal for an up and down elevator, which is safer.

[0011] Preferably, the driving motor is fixedly connected in the limiting groove, and the number of the driving motors is two and they are symmetrically distributed.

[0012] Preferably, the driving block is slidably connected in the limiting groove, and the driving block is limited by the limiting groove so that the driving block will not be displaced during the movement.

[0013] Preferably, the sliding block is slidably connected in a limiting groove, and the inner door panel is located in the limiting groove. When the inner door panel moves, it can be limited by the limiting groove to prevent the inner door panel from tilting.

[0014] The beneficial effects of the utility model are:

[0015] 1. Through the outer door panel, drive motor, threaded rod, drive block, slide rail, slider, fixed plate and inner door panel, when employees go up and down the elevator, they press the start button, and the drive motor will drive the inner door panel to move through the drive block, and the inner door panel will slide into the limit groove. After that, the rotating motor will drive the outer door panel to flip to the floor level, so that workers can only go up and down the elevator through the outer door panel when the outer door panel is fully opened, thereby preventing construction workers from stepping on empty space due to the extension plate not being extended in time. At the same time, the flipped outer door panel can contact the floor level, which is more stable;

[0016] 2. The limit grooves are provided to limit the sliding inner door panel to prevent the inner door panel from tilting, and the moving slider can be limited to further stabilize the moving angle of the inner door panel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-6 As shown, a protective and stabilizing device for safety engineering includes an elevator car 1, in which two second door shafts 5 are rotatably connected and symmetrically distributed, and the surfaces of the second door shafts 5 are fixedly connected to outer door panels 6, in which limit grooves 8 are provided; a protective component 9, which is installed in the limit grooves 8, and a limit frame is provided in the elevator car 1.

[0026] The protection component 9 includes a drive motor 91 embedded in the limit groove 8. The drive motor 91 is fixedly connected in the limit groove 8. There are two drive motors 91 and they are symmetrically distributed. A threaded rod 92 is fixedly connected to the output end of the drive motor 91. A drive block 93 is provided outside the threaded rod 92. The drive block 93 is slidably connected in the limit groove 8. Four symmetrically distributed slide rails 94 are provided in the limit groove 8. Two symmetrically distributed sliders 95 are slidably connected to the surface of each slide rail 94. The slider 95 is slidably connected in the limit groove 8, and a fixing plate 96 is fixedly connected to the outside of the slider 95. An inner door panel 97 is fixedly connected to the surface of the fixing plate 96. The inner door panel 97 is located in the limit groove 8, and the top of the inner door panel 97 extends into the limit frame. When the inner door panel 97 is reset, the inner door panel 97 will extend into the limit frame. At this time, the elevator car 1 can be lifted and lowered. During the lifting and lowering process of the elevator car 1, the limit frame will limit the inner door panel 97 to prevent the inner door panel 97 from shaking.

[0027] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, there are four first door shafts 2 rotatably connected in the elevator car 1 and symmetrically distributed. The surface of the first door shaft 2 is fixedly connected with opening and closing door panels 3. The number of the opening and closing door panels 3 is two and they are symmetrically distributed. The surfaces of the two opening and closing door panels 3 are fixedly connected with handles 4. A rotating motor 7 is embedded and installed in the elevator car 1. The number of the rotating motors 7 is two and they are symmetrically distributed. The two rotating motors 7 are respectively located on both sides of the outer door panel 6. The rotating motor 7 is controlled by a starting button installed in the elevator car 1. When the starting button is pressed, the rotating motor 7 will drive the outer door panel 6 to flip over. When the outer door panel 6 flips over to contact the ground, the outer door panel 6 can serve as a pedal for going up and down the elevator. When the starting button is released, the rotating motor 7 will drive the outer door panel 6 to reset.

[0028] When the utility model is in use, the driving motor 91 is started, and the working driving motor 91 will drive the driving block 93 to move through the threaded rod 92. At this time, the driving block 93 will drive the inner door panel 97 to move through the fixing plate 96, and the inner door panel 97 will slide into the limiting groove 8. At the same time, the slider 95 will slide on the surface of the slide rail 94, thereby limiting the moving fixing plate 96 to prevent the fixing plate 96 from rotating with the threaded rod 92. After that, the start button is pressed and the rotating motor 7 will drive the outer door panel 6 to flip over. The outer door panel 6 can serve as a pedal for the up and down elevator, further improving the safety of the construction elevator and preventing workers from falling when going up and down the elevator.

[0029] Existing elevators generally include a car, a driving mechanism, a standard section, a guide rail, a wall attachment, a chassis, a fence, an electrical system, and the like. The elevator car 1 is installed on the surface of the guide rail, and the driving mechanism is used to drive the elevator car 1 to move up and down.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
