Description

Technical Field

[0001] The utility model relates to the technical field of freight elevator cleaning equipment, in particular to a freight elevator with an automatic dust removal mechanism. Background Art

[0002] A freight elevator is a piece of equipment used for daily lifting and transporting of goods in a building. During the long period of transporting goods, the dust in the goods will accumulate in the freight elevator. When subsequently transporting goods with higher environmental requirements, the dust in the air will fall on the surface of the goods, causing damage to the goods. Therefore, dust removal equipment needs to be installed in the cargo elevator.

[0003] For example, a freight elevator with an automatic dust removal mechanism in the prior art (publication number: CN219507423U) aims to solve the problem that untimely dust removal in the freight elevator will affect the comfort of personnel. When the freight elevator with an automatic dust removal mechanism is used, the dust inside the cargo placement slot is sensed by a dust sensor. When the dust reaches the set value of the dust sensor, the dust sensor transmits a signal to the vacuum pump, and then the vacuum pump is activated, so that the dust can be better discharged from the outside of the freight elevator body.

[0004] However, the effect of extracting dust by relying solely on a vacuum pump is poor. The reason is that the dust accumulates in the placement slot for a long time, and due to the influence of water vapor in the air, it will be firmly adsorbed in the placement slot. Therefore, the dust attached to the placement slot cannot be extracted by vacuuming alone. Therefore, the applicant proposes a freight elevator with an automatic dust removal mechanism with better dust removal effect. Utility Model Content

[0005] The utility model aims to solve the problems existing in the prior art and proposes a freight elevator with an automatic dust removal mechanism.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a freight elevator with an automatic dust removal mechanism, comprising a freight elevator car and an air pump, wherein a rotating plate is rotatably connected to the rear side of the floor in the freight elevator car, a hollow plate is elastically connected to one side of the rotating plate, and a rubber cloth for sealing is arranged between the hollow plate and the rotating plate, a plurality of brushes for cleaning the floor of the freight elevator car are arranged on one side of the hollow plate, a fan which drives the hollow plate to shake through a driving member is rotatably connected to the center of one side of the rotating plate, and an air flow hood fixed on the rotating plate is provided on the fan, an air inlet of the air flow hood is connected to the area between the rotating plate and the hollow plate, and an air pipe is connected between the air outlet of the air flow hood and the air inlet of the air pump.

[0007] Further: a spring is connected between a corner of one side of the rotating plate and the hollow plate, and the spring is located outside the rubber cloth.

[0008] Furthermore: a fixed shaft is fixedly connected to the other side surface of the hollow plate near the center, and one end of the fan blade shaft passes through the airflow cover and extends outwardly and is fixedly connected to a cam that slides with the surface of the fixed shaft.

[0009] Further: the air pump is arranged outside the freight elevator car, and the air pipe passes through the surface of the freight elevator car.

[0010] Furthermore: a dust bag is also provided on the outer wall of the freight elevator car, and the bag opening of the dust bag is connected to the air outlet of the air pump.

[0011] Furthermore: the inner wall of the freight elevator car is fixedly connected with a partition for protecting the rotating plate and the hollow plate.

[0012] Furthermore: a portion of the air pipe is arranged in a spiral shape, and an elastic rope is connected between the end of the air pipe close to the air flow cover and the outer wall of the freight elevator car.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, the rotating plate rotates to a horizontal state so that a number of brushes on the hollow plate are in contact with the floor of the freight elevator car. The air pump is started, and the air in the freight elevator car passes through the hollow plate, the airflow hood, the air pipe, and the air pump in turn.

The dust on the floor of the freight elevator car is cleaned by friction of the brush, and the cleaned dust is pumped out by the air pump along with the airflow. That is, this solution can use the air pump to extract the dust in the freight elevator car while driving the brush to move, so as to break up and extract the dust that has clumps in the freight elevator car.

[0015] 2. In the utility model, the elastic rope provided can drive the elastic rope to stretch elastically when the turn plate rotates toward a horizontal state, and then when the turn plate rotates to reset, the elastic rope elastically contracts, so that the air pipe can be correspondingly pulled out of the freight elevator car.

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] like Figure 1-6 As shown, a freight elevator with an automatic dust removal mechanism comprises a freight elevator car 1 and an air pump 4. A rotating plate 8 is rotatably connected to the rear side of the floor in the freight elevator car 1. A hollow plate 6 is elastically connected to one side of the rotating plate 8, and a rubber cloth 7 for sealing is arranged between the hollow plate 6 and the rotating plate 8. A plurality of brushes 5 for cleaning the floor of the freight elevator car 1 are arranged on one side of the hollow plate 6. A fan 14 that drives the hollow plate 6 to shake through a driving member is rotatably connected at the center of one side of the rotating plate 8. An airflow hood 10 fixed on the rotating plate 8 is sleeved on the fan 14. The air inlet of the airflow hood 10 is connected to the area between the rotating plate 8 and the hollow plate 6, and an air pipe 11 is connected between the air outlet of the airflow hood 10 and the air inlet of the air pump 4.

[0026] In this plan:

[0027] During the use of the freight elevator car 1, the rotating plate 8 is in a vertical state, which does not affect the stacking of goods in the car. To clean the dust in the freight elevator car 1, the rotating plate 8 is rotated to a horizontal state, so that the several brushes 5 on the hollow plate 6 are in contact with the floor of the freight elevator car 1, and the air pump 4 is started. The air in the freight elevator car 1 passes through the hollow plate 6, the airflow hood 10, the air pipe 11, and the air pump 4 in turn. When the airflow passes through the inside of the airflow hood 10, it drives the fan 14 to rotate, thereby realizing the shaking of the hollow plate 6 and the brush 5. The dust on the floor of the freight elevator car 1 is cleaned by friction with the brush 5, and the cleaned dust is extracted by the air pump 4 along with the airflow. That is, the present scheme can extract the dust in the freight elevator car 1 through the air pump 4, and at the same time, it can drive the brush 5 to move, so as to break up and extract the dust that has clumps in the freight elevator car 1.

[0028] like Figure 3 As shown: a spring 9 is connected between the corner of one side of the rotating plate 8 and the hollow plate 6, and the spring 9 is located outside the rubber cloth 7;

[0029] In this plan:

[0030] The provided spring 9 can fix the relative position of the hollow plate 6 and the rotating plate 8 , and the provided spring 9 can make the hollow plate 6 swing relative to the rotating plate 8 .

[0031] like Figure 4 and Figure 5 As shown: a fixed shaft 13 is fixedly connected to the other side of the hollow plate 6 near the center, and one end of the blade shaft of the fan 14 penetrates the airflow cover 10 and extends outward and is fixedly connected to a cam 12 that slides on the surface of the fixed shaft 13;

[0032] In this plan:

[0033] When the airflow drives the fan 14 to rotate, the fan shaft drives the cam 12 to rotate. Through the contact between the cam 12 and the fixed shaft 13, the fixed shaft 13 can drive the hollow plate 6 to swing appropriately in a state parallel to the rotating plate 8, thereby enabling the brush 5 to clean the floor of the freight elevator car 1.

[0034] like Figure 2 As shown: the air pump 4 is arranged outside the freight elevator car 1, and the air pipe 11 passes through the surface of the freight elevator car 1.

[0035] In addition: a dust bag 3 is also provided on the outer wall of the freight elevator car 1, and the bag opening of the dust bag 3 is connected to the air outlet of the air pump 4;

[0036] In this plan:

[0037] The air pump 4 is any common air pump currently available on the market, and the dust collecting bag 3 is provided to collect the dust-containing air drawn out by the air pump 4 and filter the dust in the air.

[0038] like Figure 6As shown: a partition plate 2 for protecting a rotating plate 8 and a hollow plate 6 is fixedly connected to the inner wall of the freight elevator car 1;

[0039] In this plan:

[0040] The partition plate 2 can act as a handrail when the rotating plate 8 and the hollow plate 6 are vertical, preventing people from touching the top edge of the rotating plate 8 and manually moving the rotating plate 8.

[0041] like Figure 2 As shown: a part of the air pipe 11 is spirally arranged, and an elastic rope 15 is connected between the end of the air pipe 11 close to the airflow cover 10 and the outer wall of the freight elevator car 1;

[0042] In this plan:

[0043] The elastic rope 15 can be elastically stretched when the turn plate 8 rotates toward a horizontal state, and then when the turn plate 8 rotates to reset, the elastic rope 15 elastically contracts, so that the air pipe 11 is correspondingly pulled out of the freight elevator car 1.

[0044] Working principle: when in use, a motor is installed in the freight elevator car 1 to drive the rotating plate 8 to rotate. When the rotating plate 8 rotates to a horizontal state, the air pump 4 is started, and the air in the freight elevator car 1 passes through the hollow plate 6, the airflow cover 10, the air pipe 11, and the air pump 4 in turn. When the airflow passes through the inside of the airflow cover 10, it drives the fan 14 to rotate. When the airflow drives the fan 14 to rotate, the fan shaft drives the cam 12 to rotate. Through the contact between the cam 12 and the fixed shaft 13, the fixed shaft 13 can drive the hollow plate 6 to swing appropriately in a state parallel to the rotating plate 8, and the dust on the floor of the freight elevator car 1 is cleaned by friction with the brush 5. The cleaned dust is extracted by the air pump 4 along with the airflow. That is, the present scheme can extract the dust in the freight elevator car 1 through the air pump 4, and at the same time, it can drive the brush 5 to move, so as to break up and extract the dust that has clumps in the freight elevator car 1.

[0045] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
