Description

Technical Field

[0001] The present application relates to the technical field of sensor devices, and in particular to a lateral pressure weight sensor device and a tower crane. Background Art

[0002] Currently, for tower cranes in the industry, most manufacturers control the safe load of tower cranes through weight limiters and torque limiters. However, some manufacturers use wireless weight sensors based on the weight detection needs of customers or construction sites. Wireless weight sensors are usually equipped with antennas. When used on site, the antennas extend too far and often interfere with surrounding objects, which can easily interfere with signal transmission or cause equipment damage. Utility Model Content

[0003] The purpose of the present application is to provide a lateral pressure weight sensor device and a tower crane in view of at least one technical problem involved in the background technology.

[0004] In order to achieve the above objectives, this application adopts the following technical solutions:

[0005] One aspect of the present application provides a lateral pressure weight sensing device, including a deformation sensor component and an equipment body component, the equipment body component including a body, an antenna and a main control board, the deformation sensor component is installed on the body, the body includes a box body, the antenna and the main control board are both installed in the box body, the antenna is in contact with the inner wall of the box body, the antenna extends along the inner wall of the box body, and the antenna and the deformation sensor are both communicatively connected to the main control board.

[0006] Optionally, a card slot is provided on the inner wall of the box body, a notch of the card slot faces the opening of the box body, and the antenna is inserted into the card slot.

[0007] The beneficial effect of this technical solution is that it is easy to position the antenna through the card slot. Since the notch of the card slot faces the opening of the box, the staff can easily insert the antenna into the card slot from the opening during the production of the lateral pressure weight sensor device, thereby reducing the production difficulty and improving the production efficiency.

[0008] Optionally, the depth direction of the card slot is the same as the depth direction of the box body, the slot opening extends obliquely relative to the depth direction of the box body, and the length direction of the antenna is the same as the extension direction of the slot opening.

[0009] The beneficial effect of this technical solution is that, that is, after the antenna is installed in the card slot, the length direction of the antenna is also inclined relative to the depth direction of the box body. In this way, the arrangement of the antenna utilizes the length of the diagonal of the inner wall of the box body, so that the length and width of the box body do not have to adapt to the length of the antenna, and can therefore be appropriately reduced, which makes it possible to reduce the volume of the box body, thereby enabling the lateral pressure weight sensor device to further reduce the space it occupies and reduce the probability of collision with surrounding objects.

[0010] Optionally, the antenna includes a plate-shaped portion, and a plate surface of the plate-shaped portion is bonded to an inner wall of the box body.

[0011] The beneficial effect of this technical solution is that it can prevent the antenna from shaking easily in the box body, thereby preventing the antenna from being damaged due to repeated shaking and repeated collisions with the inner wall of the box body, thereby extending the service life of the antenna.

[0012] Optionally, the device body assembly also includes a sensor interface and a data interface both fixed to the box body, and in the length direction of the main control board, the antenna is located on one side of the main control board, and the sensor interface and the data interface are located on the other side of the main control board.

[0013] The beneficial effect of this technical solution is that: that is, the sensor interface and the data interface are arranged separately from the antenna to avoid interference between the sensor interface and the data interface and the antenna. In the embodiment of the present application, the device body assembly also includes components such as a solar panel, a battery, and a status indicator light. The solar panel is fixed on the outer wall of the body, the battery is located in the box body, the battery is arranged below the main control board, and the indicator light and the data interface are located on the same side wall of the box body.

[0014] Optionally, the device body assembly further includes a waterproof rubber pad and a waterproof cover plate, wherein the waterproof rubber pad covers the opening of the box body, and the waterproof cover plate covers the waterproof rubber pad, and the waterproof cover plate is fixedly connected to the box body.

[0015] The beneficial effect of this technical solution is that: in this way, the internal space of the box body is sealed by the waterproof rubber pad and the waterproof cover plate, so that the antenna and various electrical appliances in the box body are not easily malfunctioned due to moisture.

[0016] Optionally, the main body also includes two connecting plates, both of which are fixed to the box body, and the two connecting plates are arranged opposite to each other. The deformation sensor assembly includes a deformation sensor, and the deformation sensor is located between the two connecting plates, and the deformation sensor is fixedly connected to the two connecting plates.

[0017] The beneficial effect of this technical solution is that since the deformation sensor itself will change in size when in use, the position of the deformation sensor is limited by the connecting plate, and it is not easy for the deformation sensor to be separated from the equipment body component due to deformation of the deformation sensor.

[0018] Optionally, a gap is left between the deformation sensor and the two connecting plates; and / or a gap is left between the deformation sensor and the top surface of the box body.

[0019] The beneficial effect of this technical solution is that in this way, sufficient space is provided for the deformation sensor to generate deformation flow, so that the problem of damage to the connecting plate or the box body due to deformation of the deformation sensor is less likely to occur.

[0020] Optionally, two connecting holes are provided on the two connecting plates, and two threaded holes are formed on opposite sides of the deformation sensor. The two connecting holes on one connecting plate are connected to the two threaded holes on one side of the deformation sensor one-to-one through bolts, and the two connecting holes on the other connecting plate are connected to the two threaded holes on the other side of the deformation sensor one-to-one through bolts.

[0021] The beneficial effect of this technical solution is that by selecting two connecting holes and two threaded holes to be connected correspondingly through bolts, the deformation sensor is not easily rotated due to a certain bolt as an axis when deforming, thereby enabling the deformation sensor to collect more accurate data.

[0022] Another aspect of the present application provides a tower crane, comprising a steel wire rope and the lateral pressure weight sensor device provided in the present application, wherein the lateral pressure weight sensor device is installed on the steel wire rope.

[0023] The technical solution provided by this application can achieve at least one of the following beneficial effects:

[0024] The lateral pressure weight sensor device and tower crane provided by the present application adopt the lateral pressure weight sensor device provided by the present application, and set the antenna inside the box body, which effectively avoids the problem of interference between the antenna and objects around the sensor device, thereby making the antenna not easy to be damaged. At the same time, since the antenna is arranged in close contact with the inner wall of the box body, the adverse effect of the thickness of the inner wall of the box body on the antenna transmission signal is reduced, thereby obtaining a better signal transmission effect. In addition, the antenna extends along the inner wall of the box body, making it difficult for the antenna to occupy the middle aperture of the box body, providing appropriate installation space for other components in the box body, so that the components in the box body are compactly arranged, the space is effectively utilized, and the volume of the box body and the lateral pressure weight sensor device can be reduced, so that the lateral pressure weight sensor device is not easy to interfere with surrounding objects, reducing the possibility of equipment damage.

[0025] The additional technical features and advantages of the present application will be more clearly explained in the following description, or can be understood through the specific practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0049] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] like Figures 1 to 6As shown, one aspect of the present application provides a lateral pressure weight sensing device, including a deformation sensor component 25 and an equipment body component 26, the equipment body component 26 includes a body, an antenna 18 and a main control board 19, the deformation sensor component 25 is installed on the body, the body includes a box body 11, the antenna 18 and the main control board 19 are both installed in the box body 11, the antenna 18 is in contact with the inner wall of the box body 11, the antenna 18 extends along the inner wall of the box body 11, and the antenna 18 and the deformation sensor are both communicatively connected with the main control board 19.

[0051] The lateral pressure weight sensor device provided in the present application sets the antenna 18 inside the box body 11, which effectively avoids the problem of interference between the antenna 18 and objects around the sensor device, thereby making the antenna 18 not easily damaged. At the same time, since the antenna 18 is set in close contact with the inner wall of the box body 11, the adverse effect of the thickness of the inner wall of the box body 11 on the signal transmitted by the antenna 18 is reduced, thereby obtaining a better signal transmission effect. In addition, the antenna 18 extends along the inner wall of the box body 11, making it difficult for the antenna 18 to occupy the middle aperture of the box body 11, providing appropriate installation space for other components in the box body 11, making the components in the box body 11 compactly arranged, and effectively utilizing the space, which can reduce the volume of the box body 11 and the lateral pressure weight sensor device, making it difficult for the lateral pressure weight sensor device to interfere with surrounding objects, thereby reducing the possibility of equipment damage.

[0052] Optionally, a slot 22 is provided on the inner wall of the box body 11, the slot 22 faces the opening of the box body 11, and the antenna 18 is inserted into the slot 22. The slot 22 is convenient for positioning the antenna 18. Since the slot 22 faces the opening of the box body, the staff can easily insert the antenna 18 into the slot 22 from the opening during the production of the lateral pressure weight sensor device, thereby reducing the production difficulty and improving the production efficiency.

[0053] Optionally, the depth direction of the slot 22 is the same as the depth direction of the box body 11, the slot of the slot 22 extends obliquely relative to the depth direction of the box body 11, and the length direction of the antenna 18 is the same as the extension direction of the slot. That is to say, after the antenna 18 is installed in the slot 22, the length direction of the antenna 18 is also oblique relative to the depth direction of the box body 11. In this way, the arrangement of the antenna 18 utilizes the length of the diagonal of the inner wall of the box body 11, so that the length and width of the box body 11 do not need to adapt to the length of the antenna 18, and can be appropriately reduced, which makes it possible to reduce the volume of the box body 11, thereby enabling the lateral pressure weight sensor device to further reduce the space occupied and reduce the probability of collision with surrounding objects.

[0054] Optionally, the antenna 18 includes a plate-shaped portion, and the plate surface of the plate-shaped portion is bonded to the inner wall of the box body 11. This can prevent the antenna 18 from shaking easily in the box body 11, thereby preventing the antenna 18 from being damaged due to repeated shaking and repeated collisions with the inner wall of the box body 11, thereby extending the service life of the antenna 18.

[0055] Optionally, the device body component 26 further includes a sensor interface 08 and a data interface 09 both fixed to the box body 11. In the length direction of the main control board 19, the antenna 18 is located on one side of the main control board 19, and the sensor interface 08 and the data interface 09 are located on the other side of the main control board 19. In other words, the sensor interface 08 and the data interface 09 are arranged separately from the antenna 18 to avoid interference of the sensor interface 08 and the data interface 09 with the antenna 18. In the embodiment of the present application, the device body component 26 further includes components such as a solar panel 13, a battery 20, and a status indicator light 10. The solar panel 13 is fixed on the outer wall of the body, the battery 20 is located in the box body 11, and the battery 20 is arranged below the main control board 19. The indicator light and the data interface 09 are located on the same side wall of the box body 11.

[0056] Optionally, the device body assembly 26 further includes a waterproof rubber pad 23 and a waterproof cover plate 17, wherein the waterproof rubber pad 23 covers the opening of the box body 11, and the waterproof cover plate 17 covers the waterproof rubber pad 23, and the waterproof cover plate 17 is fixedly connected to the box body 11. In this way, the internal space of the box body 11 is sealed by the waterproof rubber pad 23 and the waterproof cover plate 17, so that the antenna 18 and various electrical appliances in the box body 11 are not easily damaged by moisture.

[0057] Optionally, the body further includes two connecting plates 15, both of which are fixed to the box body 11, and the two connecting plates 15 are arranged opposite to each other, and the deformation sensor assembly 25 includes a deformation sensor 14, and the deformation sensor 14 is located between the two connecting plates 15, and the deformation sensor 14 is fixedly connected to the two connecting plates 15. Since the deformation sensor 14 itself will change in size when in use, the position of the deformation sensor 14 is limited by the connecting plate 15, and it is not easy for the deformation sensor 14 to be separated from the device body assembly 26 due to the deformation of the deformation sensor 14.

[0058] Optionally, a gap is left between the deformation sensor 14 and the two connecting plates 15; and / or a gap is left between the deformation sensor 14 and the top surface of the box body. In this way, sufficient space is provided for the deformation sensor to deform, and the problem of damage to the connecting plates 15 or the box body due to deformation of the deformation sensor 14 is unlikely to occur.

[0059] Optionally, two connecting holes 16 are provided on both connecting plates 15, and two threaded holes are formed on opposite sides of the deformation sensor 14. The two connecting holes 16 on one connecting plate 15 are connected to the two threaded holes on one side of the deformation sensor 14 through bolts 24 in a one-to-one correspondence, and the two connecting holes 16 on the other connecting plate 15 are connected to the two threaded holes on the other side of the deformation sensor 14 through bolts 24 in a one-to-one correspondence. Selecting two connecting holes 16 and two threaded holes to be connected correspondingly through bolts 24 makes it difficult for the deformation sensor 14 to rotate due to a certain bolt 24 as an axis during deformation, thereby enabling the deformation sensor 14 to collect more accurate data. In the embodiment of the present application, it is preferred to set a nameplate 12 on the outer wall of the connecting plate 15 to mark the position of the magnetic switch for easy operation by the staff.

[0060] Another aspect of the present application provides a tower crane, including a steel wire rope 100 and a lateral pressure weight sensor device provided in an embodiment of the present application, wherein the lateral pressure weight sensor device is installed on the steel wire rope 100 .

[0061] The tower crane provided in the present application adopts the lateral pressure weight sensor device provided in the present application, and the antenna 18 is arranged inside the box body 11, which effectively avoids the problem of interference between the antenna 18 and the surrounding objects of the sensor device, thereby making the antenna 18 not easy to be damaged. At the same time, since the antenna 18 is arranged in close contact with the inner wall of the box body 11, the adverse effect of the thickness of the inner wall of the box body 11 on the signal transmitted by the antenna 18 is reduced, thereby obtaining a better signal transmission effect. In addition, the antenna 18 extends along the inner wall of the box body 11, making it difficult for the antenna 18 to occupy the middle aperture of the box body 11, providing appropriate installation space for other components in the box body 11, making the components in the box body 11 compactly arranged, and effectively utilizing the space, which can reduce the volume of the box body 11 and the lateral pressure weight sensor device, making the lateral pressure weight sensor device not easy to interfere with surrounding objects, and reducing the possibility of equipment damage.

[0062] In the embodiment of the present application, the deformation sensor assembly 25 also includes a first wire rope pressure block 02, a second wire rope pressure block 06, a locking nut 01, a signal connector 07 and an anti-fall rope 04. A wire rope fixing groove 05 is formed on the first wire rope pressure block 02 and the second wire rope pressure block 06. The wire rope 100 is installed in the wire rope fixing groove 05. The wire rope fixing groove 05 matches the wire rope 100, which can completely avoid the side slip and deviation problems of the wire rope 100 during use. The signal connector 07 is connected to the sensor interface 08. Two screws 03 are fixed on the top of the deformation sensor 14. The first wire rope pressure block 02 is mounted on the two screws 03, and the locking nut 01 cooperates with the screw threads.

[0063] When the wire rope 100 is pulled by force, the deformation sensor 14 is deformed. The magnitude of the force on the wire rope 100 is linearly related to the deformation of the deformation sensor 14. When the deformation sensor 14 is deformed, the resistance of the strain resistor of the deformation sensor 14 changes accordingly, generating a voltage difference. By collecting the change in the voltage difference, the deformation of the deformation sensor 14 can be measured, and then the weight of the suspended object on the wire rope 100 can be indirectly measured.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
