Description

Technical Field

[0001] The utility model belongs to the technical field of elevator maintenance warning, and in particular relates to a warning device for elevator maintenance. Background Art

[0002] Elevators have been part of people's lives for 170 years. In 1854, at the World Expo held in the Crystal Palace in New York, American Elisha Graves Otis first demonstrated his invention to the world. Humans have a long history of using lifting tools to transport goods and people. Life goes on, technology develops, and elevators are also improving. Over the past 170 years, the emergence of elevators has greatly saved pedestrians' time, but elevators need to be repaired and maintained, and during repairs, safety failures often occur when passengers ride in elevators under repair.

[0003] Existing warning signs for elevator maintenance are generally large in size, inconvenient for maintenance technicians to carry, and have poor stability. They are easy to flip over when hit. If the warning sign is not promptly picked up after toppling over, other people cannot see the warning sign in time and may mistakenly get on the faulty elevator, resulting in a safety accident. Utility Model Content

[0004] The purpose of the utility model is to provide a warning device for elevator maintenance, which is used to solve the problems mentioned in the background technology.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] An elevator maintenance warning device comprises a base, wherein manual suction cups are installed on the left and right lower sides of the base, two telescopic mechanisms are hinged on the left and right sides of the base, and a fabric enclosure is connected between the two telescopic mechanisms;

[0007] The telescopic mechanism includes a fixed rod, a movable rod and a rotating shaft. The rotating shaft is hinged to the base. The fixed rod is fixed on the upper side of the rotating shaft, and the two fixed rods are arranged front to back. The movable rod is sleeved on the upper side of the fixed rod and slidably connected to the fixed rod up and down. A spring that is transmission-connected to the fixed rod is installed on the inner side of the movable rod. Synchronous components for controlling the fixed rods are provided on the lower sides of the two rotating shafts, and a linkage component is also provided between the two movable rods.

[0008] The synchronization component includes an arc-shaped hydraulic cylinder and an arc-shaped piston rod. The arc-shaped hydraulic cylinder is sleeved on the outside of the arc-shaped piston rod, and the arc-shaped hydraulic cylinder and the arc-shaped piston rod are both colinear with the axis of the rotating shaft. The arc-shaped hydraulic cylinder is fixedly connected to the base, the arc-shaped piston rod is transmission-connected to the rotating shaft, and the left and right arc-shaped hydraulic cylinders are connected by pipelines.

[0009] The linkage assembly includes a wire tube and a wire core, the wire core is slidably installed on the inner side of the wire tube, a wire groove is vertically opened on the side of the fixed rod, the left and right sides of the wire tube are respectively installed on the inner sides of the left and right wire grooves, one end of the wire tube is inverted and fixed on the upper side of the wire groove of one of the fixed rods, and the other end of the wire tube is upright and fixed on the lower side of the wire groove of the other fixed rod, and both ends of the wire core are transmission-connected to the lower side of the movable rod.

[0010] A spiral spring is installed on the side of one of the rotating shafts, a rubber belt is arranged on the rear side of the middle part of the base, and a belt buckle matching the rubber belt is arranged on the front side of the base.

The manual suction cup prevents the warning device from tipping over. At the same time, the spring can raise the fabric enclosure higher when in use, making the fabric enclosure more eye-catching and improving the safety of the warning device. The arc-shaped hydraulic cylinder and arc-shaped piston rod make the synchronous component structure simple and reliable. The hydraulic transmission can transmit greater power while making the synchronous component lighter, reducing the overall weight of the warning device and making it more convenient to carry. The cooperation between the wire tube and the wire core can achieve the simultaneous shortening of the telescopic mechanisms on the left and right sides. Compared with the traditional mechanical transmission system, the control method using the wire tube and the wire core is much better. The design is simpler, and maintenance and troubleshooting become easier. In addition, it has higher accuracy and reliability, thereby improving the operating accuracy and stability of the machine. When the telescopic mechanism is opened, the scroll spring can make the telescopic mechanism quickly pop up and open, and at the same time, it can keep the telescopic mechanism in a vertical state when it is opened, thereby improving the stability of the warning device. The rubber belt and belt buckle can more conveniently bundle and store the telescopic mechanism, thereby improving the ease of use of the warning device. The design of the elastic enclosure can reduce the volume during storage, making it more convenient to store.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-7 As shown, a warning device for elevator maintenance includes a base 1, manual suction cups 2 are installed on the left and right lower sides of the base 1, two telescopic mechanisms are hinged on the left and right sides of the base 1, and a fabric enclosure 3 is connected between the two telescopic mechanisms;

[0025] The telescopic mechanism includes a fixed rod 4, a movable rod 5 and a rotating shaft 6. The rotating shaft 6 is hinged to the base 1. The fixed rod 4 is fixed on the upper side of the rotating shaft 6, and the two fixed rods 4 are arranged front to back. The movable rod 5 is sleeved on the upper side of the fixed rod 4 and slidably connected to the fixed rod 4 up and down. A spring 7 that is transmission-connected to the fixed rod 4 is installed on the inner side of the movable rod 5. Synchronous components for controlling the fixed rod 4 are provided on the lower sides of the two rotating shafts 6, and a linkage component is also provided between the two movable rods 5.

[0026] The base 1 is in the shape of a long box as a whole, and the telescopic mechanisms on the left and right sides are arranged front and back in a manner similar to mandarin ducks, and do not interfere with each other when rotating up and down. When the entire warning device is not in use, the telescopic mechanisms on the left and right sides are in a shortened state and horizontally stored inside the base 1. When the warning device needs to be used, the manual suction cup 2 on the lower side of the base 1 is adsorbed to the upper side of the floor tile at the position where the warning is required, and one of the telescopic mechanisms is erected upward. The synchronization component can enable the telescopic mechanisms on the left and right sides to open outward and fold inward at the same time. The spring 7 causes the movable rod 5 on the upper side of the fixed rod 4 to extend upward, and the fabric enclosure 3 located between the telescopic mechanisms can serve as a warning.

[0027] When the warning device is used, the movable rod 5 of one of the telescopic mechanisms is slid downward and laid down toward the middle. The linkage device can shorten the telescopic mechanisms on the left and right sides at the same time. At this time, the telescopic mechanisms and the fabric enclosure 3 are stored inside the base 1.

[0028] The cooperation between the telescopic mechanism and the base 1 allows the warning device to be folded and stored when not in use, reducing the size of the warning device for easier carrying by maintenance personnel. The manual suction cup 2 prevents the warning device from tipping over. At the same time, when in use, the spring 7 can raise the fabric enclosure 3 higher, making the fabric enclosure 3 more eye-catching and improving the safety of the warning device.

[0029] The synchronization component includes an arc-shaped hydraulic cylinder 8 and an arc-shaped piston rod 9. The arc-shaped hydraulic cylinder 8 is sleeved on the outside of the arc-shaped piston rod 9, and the arc-shaped hydraulic cylinder and the arc-shaped piston rod 9 are both colinear with the axis of the rotating shaft 6. The arc-shaped hydraulic cylinder 8 is fixedly connected to the base 1, the arc-shaped piston rod 9 is transmission-connected to the rotating shaft 6, and the left and right arc-shaped hydraulic cylinders 8 are connected by pipelines.

[0030] The arc piston rod 9 fits tightly inside the arc hydraulic cylinder 8. The arc hydraulic cylinders 8 and the arc piston rod 9 on the left and right sides are installed in the same direction. Hydraulic oil is installed inside the arc hydraulic cylinder 8. Since the arc piston rods 9 on the left and right groove sides are connected by pipelines, when any telescopic mechanism is opened outward, the fixed rod 4 on the right side drives the arc piston rod 9 on the right side to contract. At this time, the arc piston rod 9 on the left side is synchronously extended and drives the rotating shaft 6 on the left side to rotate. At this time, the telescopic mechanism on the left side is opened synchronously with the telescopic mechanism on the right side. Conversely, when it is necessary to rotate the two telescopic mechanisms toward the middle to retract, only one side of the telescopic mechanism needs to be rotated toward the middle, and the left and right groups of telescopic mechanisms can be folded toward the middle synchronously.

[0031] The arc-shaped hydraulic cylinder 8 and the arc-shaped piston rod 9 make the structure of the synchronization component simple and reliable. The hydraulic transmission can transmit greater power while making the weight of the synchronization component lower, reducing the overall weight of the warning device and making it more convenient to carry.

[0032] The linkage assembly includes a wire tube 11 and a wire core 12. The wire core 12 is slidably installed on the inner side of the wire tube 11. A wire groove 10 is vertically opened on the side of the fixed rod 4. The left and right sides of the wire tube 11 are respectively installed on the inner sides of the left and right wire grooves 10. One end of the wire tube 11 is inverted and fixed on the upper side of the wire groove 10 of one of the fixed rods 4, and the other end of the wire tube 11 is upright and fixed on the lower side of the wire groove 10 of the other fixed rod 4, and both ends of the wire core 12 are transmission connected to the lower side of the movable rod 5.

[0033] The wire tube 11 is installed inside the wire trough 10 and will not interfere with the upward and downward sliding of the movable rod 5. When the movable rod 5 needs to be retracted downward, the movable rod 5 on the inverted side of the wire tube 11 is pressed downward, and the wire core 12 on this side is elongated, and the wire core 12 on the other side is shortened, thereby driving the movable rod 5 on the other side to descend. At this time, the movable rods 5 on the left and right sides slide downward synchronously. When the staff presses the movable rod 5 downward and rotates it to the middle, the telescopic mechanism is stored.

[0034] The cooperation between the wire tube 11 and the wire core 12 can realize the simultaneous shortening of the telescopic mechanisms on the left and right sides. Compared with the traditional mechanical transmission system, the control method using the wire tube 11 and the wire core 12 is simpler, and maintenance and troubleshooting become easier. In addition, it has higher accuracy and reliability, thereby improving the operating accuracy and stability of the machine.

[0035] A spiral spring 13 is installed on the side of one of the rotating shafts 6, a rubber belt 14 is provided on the rear side of the middle part of the base 1, and a belt buckle 15 matching the rubber belt 14 is provided on the front side of the base 1.

[0036] One end of the spiral spring 13 is transmission-connected to the fixed rod 4, and the other end of the spiral spring 13 is fixedly connected to the base 1, and the elastic direction of the spiral spring 13 is the same as the direction of opening of the telescopic mechanism. When the telescopic mechanism is opened, the telescopic mechanism can quickly pop up and open, and at the same time, the telescopic mechanism can maintain a vertical state when opened, thereby improving the stability of the warning device. The rubber belt 14 cooperates with the belt buckle 15 to more conveniently bundle and store the telescopic mechanism, thereby improving the convenience of using the warning device.

[0037] The fabric enclosure 3 is an elastic enclosure, and the elastic enclosure is fixedly connected to the two movable rods 5. A luminous warning sign 16 and a reflective warning sign 17 are provided in the middle of the elastic enclosure.

[0038] The design of the elastic enclosure can reduce the volume when stored, making it more convenient to store. The luminous warning sign 16 and the reflective warning sign 17 can enhance the warning effect when the light is insufficient.

[0039] An auxiliary bracket 18 is horizontally hinged on the lower side of the base 1 .

[0040] When the warning device is in use, the auxiliary bracket 18 can be rotated to make it perpendicular to the base 1. The auxiliary bracket 18 cooperates with the base 1 to further improve the stability of the warning device. At the same time, when not in use, the auxiliary bracket 18 can be rotated parallel to the base 1 for easy storage and improved usability.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
