Description

Technical Field

[0001] This utility model belongs to the field of elevator door sill technology, and relates to an elevator door sill and a dust removal structure. Background Technology

[0002] The main shortcomings of existing elevator door sills in terms of dust control and cleaning lie in their design structure. As the contact point between the elevator door and the ground, the sill often has gaps and grooves, which easily accumulate dust and debris. Due to the grooves in the sill, dust and small particles are easily drawn in and difficult to remove with simple sweeping, especially with frequent elevator use, where dust accumulation is even faster. To ensure the proper opening and closing of the elevator door, the sill needs a certain depth and structural complexity, which provides a hiding place for dust. Furthermore, the opening and closing of the elevator door creates airflow, bringing dust into the gaps in the sill.

[0003] Conventional methods include regular cleaning with tools such as vacuum cleaners and brushes, or wiping with a damp cloth. In some cases, compressed air may be used to blow away dust from crevices. However, these methods have the drawback that they usually only remove surface dust and are not very effective at removing dust that is deeply embedded in crevices. Frequent cleaning is required to maintain cleanliness, which is both time-consuming and labor-intensive. Therefore, there is an urgent need for an elevator door sill and dust removal structure to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an elevator door sill and a dust removal structure to solve the problems mentioned in the background technology.

[0005] This utility model is achieved through the following technical solution: an elevator door sill and dust removal structure, including: a top seat and an air duct, a set of cars is provided at the lower end of the top seat, a set of elevator sills is provided at the front of the lower end of the cars to provide elevator leveling accuracy at the front of the elevator, and several sets of dust removal air inlets are provided inside the elevator sills to draw in dust and debris.

[0006] The several sets of dust removal air intakes are arranged in a strip structure, and each set has an internal cavity for drawing in and storing dust and debris. The rear ends of the left and right sides of the internal cavity are respectively provided with a set of air ducts for drawing in the dust and debris inside the internal cavity. The rear side of the right air duct is provided with a vacuum pump one for providing right-side suction for the dust and debris inside the internal cavity, and the rear side of the left air duct is provided with a vacuum pump two for providing left-side suction for the dust and debris inside the internal cavity. Both sets of air ducts are provided with a storage cavity for accumulating and storing dust and debris. The connection between the storage cavity and vacuum pump one and vacuum pump two is provided with a filter element for filtering and blocking dust and impurities.

[0007] In a preferred embodiment, vacuum pump one and vacuum pump two are of the same specifications and are respectively sealed and connected to a set of air ducts. The lower end of the elevator sill is provided with a set of sill guard plates for support. In actual use, when the elevator stops at a floor, its elevator sill is flush with the front side of the elevator on the opposite floor. At the same time, when people enter the car, the dust carried by the soles of their shoes accumulates and disperses on the elevator sill. By using vacuum pump one and vacuum pump two, air can be drawn in through the air ducts. The two sets of air ducts concentrate the dust accumulated inside the internal cavity and the dust dispersed above the dust removal air intake into the internal cavity and the branch pipes. The dust and other debris are further drawn into the storage cavity inside the air ducts for centralized cleaning by relevant elevator maintenance personnel.

[0008] In a preferred embodiment, a set of sill support platforms is provided on the upper rear side of the elevator sill to provide support. A set of side support plates is provided at the lower end of the middle position on the left and right sides of the sill support platforms to provide support for vacuum pump one and vacuum pump two.

[0009] In a preferred embodiment, the lower end of the side support plate is provided with a set of lower support platforms for providing lower support force to vacuum pump one and vacuum pump two, and the left and right sides of the sill support platform are respectively provided with two sets of support rods for connecting to the outer sides of the left and right ends of the car and providing support tension to the sill support platform.

[0010] In a preferred embodiment, the two sets of support rods on each side are arranged in a triangular structure, and the support rods are fixed to the sill support platform and the outside of the car by bolts.

[0011] In a preferred embodiment, the support rod is a steel cable, the upper end of the side connecting frame plate is connected and fixed to the sill support platform, and the outer sides of the left and right ends of the side connecting frame plate are movably fitted and connected to the inner sides of the left and right ends of the lower support platform.

[0012] In a preferred embodiment, the outer sides of the left and right ends of the side connecting frame plate are connected and fixed to the left and right ends of the lower support platform through support springs and locking bolts. A set of support diagonal rods is provided on the rear side of the sill guard plate for supporting it. The two sets of support diagonal rods are set in an inclined structure and are fixed to the lower front end of the sill support platform through bolts. When the elevator is in use, its elevator sill provides an overall connection effect through the sill support platform, thereby keeping the elevator sill and the car synchronously connected. At the same time, several sets of support tie rods are used to maintain the connection effect between the car and the sill support platform. During the use of the elevator, the side connecting frame plate and the lower support platform are connected by support springs, which can effectively reduce the car vibration caused by the operation of vacuum pump one and vacuum pump two and improve the stability of elevator operation.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are: by using vacuum pump one and vacuum pump two, air can be drawn in through the air duct, and the two sets of air ducts can concentrate the dust accumulated inside the internal cavity and the dust scattered at the top of the dust removal air intake into the internal cavity and the branch pipe, and further draw the dust and other debris into the storage cavity inside the air duct for accumulation, so that relevant elevator maintenance personnel can clean it in a concentrated manner.

[0014] During elevator operation, the elevator sill provides an overall connection through the sill support platform, thereby maintaining the synchronous connection between the elevator sill and the car. At the same time, several sets of support rods maintain the connection between the car and the sill support platform. During elevator operation, the side connecting plate and the lower support platform are connected by support springs, which can effectively reduce the car vibration caused by the operation of vacuum pump one and vacuum pump two, and improve the stability of elevator operation.
