Description

Technical Field

[0001] The invention relates to the technical field of elevator protection, and more particularly to a spark-proof and explosion-proof elevator safety clamp wedge. Background Art

[0002] The elevator safety clamp wedge is a safety device used in elevator maintenance. Its function is to prevent the elevator from suddenly falling or rising when the elevator is under maintenance, ensuring the safety of maintenance personnel. The elevator safety clamp wedge can be firmly fixed on the elevator guide rail to prevent unnecessary operation and create a safe working environment.

[0003] The main working principle of the elevator safety clamp wedge is to keep the elevator in a fixed position by preventing the sliding and movement of the elevator running parts. Specifically, when the safety clamp wedge is placed between the elevator rails or related components, a stable support is generated in the mechanical design, making it impossible for the elevator to start or move accidentally.

[0004] Safety clamp wedges are generally made of specially designed shapes and materials. When used, they can firmly clamp the corresponding parts, increase friction, and thus prevent the elevator from sliding or moving. This design can effectively ensure that the elevator remains stationary during maintenance, parking or emergency situations, improve safety and reduce the possibility of accidents.

[0005] However, the common elevator safety clamp wedges lack certain spark prevention and protection effects when preventing the elevator from falling, which leads to sparks and static electricity diffusion during emergency braking, which can easily cause fire. Therefore, it is particularly important to develop a device that can suppress sparks and static electricity and has a certain protective effect for the installation and operation of dry elevators. This not only helps to evaluate the product life, but also provides data support for improving design and improving product quality. Summary of the invention

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example:

[0036] See also Figure 1-8 A spark-proof and explosion-proof elevator safety clamp wedge comprises: a bottom plate 18, a mounting plate 1 welded to both sides of the upper end of the bottom plate 18, a threaded column 5 rotatably mounted on the middle part of the surface of the mounting plate 1, a fixed seat 2 rotatably mounted on one side of the threaded column 5, a moving block 6 that can move up and down is provided on one side of the fixed seat 2, a moving block 2 8 that can move along the inclined surface of the moving block 6 is provided on one side of the moving block 6, protective mechanisms 33 are provided on both sides of the moving block 2 8 and the mounting plate 1, and a limiting nail 14 is inserted on the surface of the mounting plate 1, and the limiting nail 14 is fixedly connected to one side of the fixed seat 2.

[0037] In a specific embodiment of the present invention, the protective mechanism 33 includes a mounting frame 12, and a column part matching with a nut 13 is fixed on the outer wall of the mounting frame 12. The nut 13 is rotatably installed on the outer wall of the column, and the number of the nut 13 is adjustable. The mounting frame 12 is fixed between the outermost nut 13 and the penultimate nut 13.

[0038] Specifically, the number of adjusting nuts 13 located between the mounting brackets 12 and the mounting plate 1 can adjust the distance between the mounting brackets 12, thereby facilitating the adjustment of the spacing between the arc plates 9.

[0039] In a specific embodiment of the present invention, a positioning plate is designed in the middle of the mounting frame 12, and an arc-shaped plate 9 is fixed to the inner side of the positioning plate.

[0040] Specifically, after the moving block 28 clamps the safety rope 23 inwardly, the arc plate 9 can prevent the rubber pad 4 on the surface from detaching from the surface of the moving block 28 at high speed under the strong friction effect and hitting the surrounding electrical control equipment, affecting the subsequent normal use of the device.

[0041] In a specific embodiment of the present invention, telescopic columns 30 are fixedly welded to the outer walls of both sides of the moving block 2 8 , a telescopic rod 29 is inserted inside the telescopic column 30 , a slider 32 is fixed to one side of the telescopic rod 29 , and the slider 32 is inserted into one side of the mounting frame 12 .

[0042] Specifically, the telescopic rod 29 and the telescopic column 30 are used to fix the longitudinal position of the movable block 28 so that it will not move up and down relative to the mounting frame 12. Then the slider 32 can ensure the fixing effect between the telescopic rod 29 and the mounting frame 12, so that the movable block 28 can move laterally relative to the mounting frame 12, thereby achieving the effect of centering the safety rope 23.

[0043] In a specific embodiment of the present invention, the protective mechanism 33 also includes a suppressor 11, an electrostatic eliminator 7 and a dryer 20. The suppressor 11 is fixedly installed on both sides of the moving block 28, the electrostatic eliminator 7 is fixedly installed on the upper end of the moving block 28, and a rubber pad 4 with an intermittent protrusion design is provided on the opposite side of the moving block 28. The dryer 20 is fixedly installed on the upper end of the bottom plate 18.

[0044] Specifically, the rubber pad 4 can increase the moving block 28 and the safety rope 23 to shorten the braking distance under the condition of relative clamping. The suppressor 11 can reduce or eliminate the energy of the spark through the built-in chemical reaction when a certain amount of air flow is introduced around it, ensuring that the spark suppression effect is achieved when the spark is generated, preventing the spark from spreading. The static eliminator 7 can reduce the generation of static electricity and the dryer 20 can ensure that the air in a certain periphery around it is dry, preventing the normal operation of the electronic device from being affected by the humid environment. The working principle of the static eliminator 7 is based on the principle of ionization and electric shock to neutralize the charge, including a metal plate and a high-voltage power supply. When the static eliminator 7 is powered on, the metal plate will be charged, and then through the action of the electric field, the charged metal plate is brought close to the object that needs to eliminate static electricity, so that the charged charge flows to the ground through the metal plate, thereby achieving the purpose of eliminating static electricity. The static eliminator 7 is widely used in the electronics, semiconductor, optics, medicine and other industries to eliminate static electricity generated in the production process and prevent static electricity from causing damage to the product. Since there are many models of dryers 20 on the market, as long as they can meet the effect of drying the internal gas in a certain space, the user can choose the model according to its use effect.

[0045] In a specific embodiment of the present invention, a guide rail 2 10 is opened on the outer side of the moving block 16, the fixed seat 2 is inserted into the guide rail 2 10, a guide rail 3 is opened on the inner side of the moving block 16, the moving block 2 8 is inserted into the guide rail 3, and the relative surfaces of the moving block 2 8 and the moving block 1 6 are inclined.

[0046] Specifically, by utilizing the design of the relative inclined surfaces, when the moving block 1 6 moves longitudinally, a force can be applied to the moving block 2 8 along the inclined surface. The separation of this force will center the moving block 2 8 to achieve a clamping effect on the safety rope 23 .

[0047] In a specific embodiment of the present invention, a cross blade 19 is formed on one side of the threaded column 5 . The threaded column 5 is located outside the mounting plate 1 and is rotatably mounted with two nuts 21 . A gasket is inserted between the nuts 21 .

[0048] Specifically, a cross screwdriver can be used to rotate the threaded column 5 when the nut 21 is loose, so as to adjust the distance between the fixing seats 2 and adapt to the safety ropes 23 of different diameters. When the nut 21 is tightened, the position of the fixing seat 2 can be fixed.

[0049] In a specific embodiment of the present invention, a positioning hole 17 is opened on the surface of the bottom plate 18. The bottom plate 18 is located at the lower end of the moving block 1 6 and the moving block 2 8 and is hollow in design. A bracket 31 is fixed to one side of the bottom plate 18 away from the moving block 1 6. A rotating plate 16 is rotatably installed between the brackets 31. A pendulum 22 is provided on the side of the rotating plate 16 facing the moving block 2 8. The lower end of the pendulum 22 is circular in design and fits with the moving block 1 6. A rotating block 15 is rotatably installed on the other side of the rotating plate 16, and a safety rope 23 is fixed to the upper end of the rotating block 15.

[0050] Specifically, after the safety rope 23 tightens the rotating plate 16 , a huge thrust is applied to the moving block 16 through the pendulum 22 , thereby realizing the longitudinal movement of the moving block 16 .

[0051] In a specific embodiment of the present invention, a roller 26 is fixedly installed above the bottom plate 18, a safety rope 23 is connected across the outer wall of the roller 26, limit keys 25 distributed in a circular array are fixed to the inner wall of the roller 26, a fixing bar 24 is fixedly installed in the middle of the roller 26, and limit rods 27 are rotatably installed on both sides of the fixing bar 24, and a spring 28 is connected between the limit rod 27 and the fixing bar 24.

[0052] Specifically, when the elevator suddenly falls, the rotation speed of the roller 26 increases, and under the action of centrifugal force, the limit rod 27 opens outward and is inserted between the limit keys 25, so that the roller 26 is fixed and cannot rotate.

[0053] A method for using a spark-proof and explosion-proof elevator safety clamp wedge comprises the following steps:

[0054] When the device is used, the bottom plate 18 is first fixed at the lower end of the elevator, the elevator safety rope 23 is passed through the moving block 28 and placed, and the roller 26 is fixed at the upper end of the elevator shaft. The safety rope 23 crosses the roller 26 and is wound in a U shape. When the elevator moves up and down normally, the roller 26 rotates under the traction of the safety rope 23. At this time, the limit rod 27 is not inserted into the gap between the limit keys 25 under the action of the tension of the spring 28. When the elevator suddenly falls, the speed of the roller 26 increases, and the limit rod 27 opens outwards under the action of centrifugal force and is inserted between the limit keys 25, so that the roller 26 is fixed and cannot rotate;

[0055] When the roller 26 is suddenly locked, the safety rope 23 pulls the rotating plate 16 upwards. Under the action of the lever, the pendulum 22 on the other side of the rotating plate 16 applies pressure inwards to the moving block 16 to drive the moving block 16 to move on one side of the fixed seat 2. Since the moving block 28 is fixed in its original position by the telescopic rod 29 and the telescopic column 30 in cooperation with the mounting frame 12, in the case of the inclined surface design on the opposite sides of the moving block 16 and the moving block 28, the moving block 28 squeezes inwards and clamps the safety rope 23 with huge pressure, thereby limiting the elevator from moving further downwards.

[0056] After the elevator has controlled the position, due to the surface design of the limit key 25, the limit column will not rotate back under the action of the spring 28, so that the elevator will always remain in a certain position and need to wait for the arrival of rescue personnel to return to the original position;

[0057] In the event of an accident, the suppressor 11 and the static eliminator 7 designed on the surface of the moving block 28 will clamp the safety rope 23 in the moving block 28, and electric sparks and static electricity and the rubber block are prone to collapse under the strong friction. At this time, the suppressor 11 can be used to reduce the generation of sparks and the static eliminator 7 can remove static electricity during normal operation. When the rubber pad 4 is damaged and collapsed, the arc-shaped protective plate can protect both sides to prevent the rubber pad 4 from flying outward and damaging other devices. The dryer 20 can ensure the drying effect of the entire device under normal operation under a certain environment, ensuring the stable use of electrical components.

[0058] After long-term use, the nut 21 can be loosened, and the threaded column 5 after loosening the nut 21 can rotate, so that it can drive the fixing seat 2 to move inward or outward, so as to adapt to different diameters of the safety rope 23.

[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and improved concepts of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
