Description

Technical Field

[0001] The utility model relates to the field of lifting devices, in particular to a lifting device capable of being weighed. Background Art

[0002] In the field of logistics, during the process of cargo handling, the traditional working method often requires the staff to estimate the weight of the cargo in advance or weigh the cargo separately, and then further determine the specific number of cargo handling and the amount of cargo handled each time based on the load-bearing weight of the lifting and handling device and the weight of the cargo to be handled. For cargo located on high shelves, the height of the cargo lifting and handling device also needs to be adjusted according to the specific placement and height of the cargo. This working method is not only inefficient, but also easily increases the burden on the staff, and also makes it impossible to maximize the function of the lifting and handling device. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a weighable lifting device to solve at least one of the above-mentioned technical problems. The specific contents are as follows:

[0004] A weighable lifting device comprises a base, a loading assembly, a lifting assembly and a weight detection component, wherein one end of the loading assembly is slidably connected to the base.

[0005] The lifting assembly includes: a driving mechanism, a lifting rod, a transverse rod, a rotating member and a chain; the fixed ends of the driving mechanism and the lifting rod are fixedly connected to the base; the movable end of the lifting rod is connected to the middle part of the transverse rod, and the two ends of the transverse rod are respectively connected to a rotating member, the middle part of the chain is slidably connected to the rotating member, one end of the chain is connected to the load-carrying assembly, and the other end of the chain is connected to the base through a weight detection member. In some specific embodiments, the load-carrying assembly includes a fork and a guide plate. Among them, one end of the fork is fixedly connected to the guide plate; the guide plate extends along a preset first direction, and the two ends of the guide plate are slidably connected to the base along the first direction. In actual applications, the fork is perpendicular to the plane where the guide plate is located, and the fork is used to obtain goods from an external shelf, carry goods, or place goods on an external shelf.

[0006] In some specific embodiments, the base includes a base frame and at least two guide posts vertically mounted on the base frame along a first direction, and two ends of the guide plate are slidably connected to the guide posts along the first direction. In practical applications, at least two guide posts are included, which are distributed at both ends of the guide plate.

[0007] In some specific embodiments, a guide member is further included, and a track is formed on the guide column in the first direction. The guide plate is slidably connected to the track through the guide member, and the guide member is used to slide along the track to drive the guide plate to rise and fall.

[0008] In some specific embodiments, the guide member includes a guide wheel. In one embodiment, each guide column is slidably connected to the guide plate in the first direction through at least two guide wheels. In practical applications, the guide member can be an I-beam, wherein the recessed structures on both sides of the structure of the I-beam can be further formed into a track for the object to be locked, and at least one guide wheel is respectively provided above and below a track of each I-beam to connect the guide plate, and a plurality of guide wheels in a track can further stabilize the moving direction of the guide plate, so that the guide plate will not deviate from the direction during the movement. Furthermore, the lifting and lowering of the goods on the loading assembly can be made more stable.

[0009] In some specific embodiments, the base further includes a transverse reinforcing rib connected to the guide column in a preset second direction, the second direction being perpendicular to the first direction. One end of the chain is connected to the object-carrying assembly, and the other end of the chain is connected to the base through a weight detection member.

[0010] In some specific embodiments, a sensor component is further included, which includes a sensed member located on the side of the carrier component facing the base and a sensing member located on the side of the base facing the carrier component; the sensing member is used to measure the lifting height of the carrier component by sensing the position of the sensed member.

[0011] In a specific embodiment, the sensed member is arranged on the side of the guide plate facing the guide column, and the sensing member is arranged on the side of the guide column facing the guide plate. There may be multiple sensed members and sensing members. For example, sensing members are arranged at different heights along the first direction on the guide column. When the lifting assembly drives the carrier assembly to lift, different sensing members on the guide column sense the presence of the sensed member on the guide plate at different heights, thereby measuring the lifting height of the carrier assembly.

[0012] Furthermore, the sensed component and the sensing component may be respectively arranged on the chassis and the fork, and the lifting height of the loading component may be measured by radar ranging or infrared ranging.

[0013] In some specific embodiments, the plane where the chassis is located is parallel to the plane where the forks are located. The lowest height of the forks is lower than or equal to the height of the plane where the chassis is located, and the highest height of the forks is lower than or equal to the height of the highest point of the guide column.

[0014] In some specific embodiments, the driving mechanism includes an oil pump and an oil pipe connected to each other, and the oil pump is connected to the lifting rod through the oil pipe.

[0015] In some specific embodiments, the lifting rod includes a hydraulic cylinder.

[0016] In actual application, the lifting rod rises or falls under the drive of the driving mechanism, and the transverse rod connected to the lifting rod and the rotating parts on both sides of the transverse rod also rise or fall with the lifting rod. Since one end of the chain is fixedly connected to the base through the weight detection part, and the other end is connected to the object-carrying component, the chain moves relative to the rotating part under the influence of the lifting and lowering of the lifting rod. When the lifting rod rises along the first direction, the length of the chain from the rotating part to the base increases, and the length of the chain from the rotating part to the object-carrying component decreases, so that the chain can further pull the object-carrying component to rise along the first direction.

[0017] During the process of the lifting of the load-carrying assembly, since both ends of the guide plate of the load-carrying assembly are movably connected to the guide column of the base through the guide member, the guide member slides upward along the first direction on the guide column, further driving the guide plate and the fork to move upward along the first direction. When the fork carries goods, the weight detection member pulls the load-carrying assembly through the chain to detect the change in pressure on the load-carrying assembly, and can further detect the weight of the goods carried on the fork.

[0018] Beneficial effect: The present application provides a weighable lifting device, comprising a base, a load-carrying component, a lifting component and a weight detection component. By setting the specific structure of the lifting component and detecting the weight of the items in the load-carrying component through the weight detection component, it is possible to verify the weight of the goods while transporting the goods, thereby eliminating additional weighing steps, effectively improving work efficiency in the logistics process, and reducing waste of human resources.

[0033] Example

[0034] This embodiment provides a weighable lifting device, and the specific scheme is as follows:

[0035] A weighable lifting device comprises a base 1, a carrying component 2, a lifting component 3 and a weight detection component 4. One end of the carrying component 2 is slidably connected to the base 1.

[0036] The lifting assembly 3 includes: a driving mechanism 31, a lifting rod 32, a transverse rod 33, a rotating member 34 and a chain 35; the fixed ends of the driving mechanism 31 and the lifting rod 32 are fixedly connected to the base 1; the movable end of the lifting rod 32 is connected to the middle part of the transverse rod 33, and the two ends of the transverse rod 33 are respectively connected to a rotating member 34, the middle part of the chain 35 is slidably connected to the rotating member 34, one end of the chain 35 is connected to the carrier assembly 2, and the other end of the chain 35 is connected to the base 1 through the weight detection member 4. In some specific embodiments, the carrier assembly 2 includes a fork 21 and a guide plate 22. Among them, one end of the fork 21 is fixedly connected to the guide plate 22; the guide plate 22 extends along a preset first direction, and the two ends of the guide plate 22 are slidably connected to the base 1 along the first direction. In actual applications, the fork 21 is perpendicular to the plane where the guide plate 22 is located, and the fork 21 is used to obtain goods from an external shelf, carry goods, or place goods on an external shelf. Figure 1 As shown, the first direction is preset as Figure 1 , Figure 3 , Figure 4 As shown in direction A in .

[0037] In some specific embodiments, the base 1 includes a base frame 11 and at least two guide posts 12 vertically mounted on the base frame 11 along a first direction, and both ends of the guide plate 22 are slidably connected to the guide posts 12 along the first direction. In practical applications, at least two guide posts 12 are included, which are distributed at both ends of the guide plate 22.

[0038] In some specific embodiments, a guide member 221 is further included, and the guide column 12 forms a track 121 in the first direction. The guide plate 22 is slidably connected to the track 121 through the guide member 221, and the guide member 221 is used to slide along the track 121 to drive the guide plate 22 to rise and fall.

[0039] In some specific embodiments, the guide member 221 includes a guide wheel. In one embodiment, each guide column 12 is slidably connected to the guide plate 22 in the first direction through at least two guide wheels. In practical applications, the guide member 221 can be an I-beam, wherein the recessed structures on both sides of the structure of the I-beam can be further formed into a track 121 that can be locked to the object, and at least one guide wheel is respectively provided above and below a track 121 of each I-beam to connect the guide plate 22, and the multiple guide wheels in a track 121 can further stabilize the moving direction of the guide plate 22, so that the guide plate 22 will not deviate from the direction during the movement. Further, the lifting and lowering of the goods on the cargo-carrying assembly 2 can be made more stable.

[0040] In some specific embodiments, the base 1 further includes a transverse reinforcing rib 13 connected to the guide column 12 in a preset second direction, and the second direction is perpendicular to the first direction. One end of the chain 35 is connected to the object-carrying assembly 2, and the other end of the chain 35 is connected to the base 1 through the weight detection member 4. By providing the transverse reinforcing rib 13 connected to the guide column 12, the firmness of the base 1 can be further strengthened. The preset second direction is specifically as follows: Figure 1 and Figure 3 As shown in direction B.

[0041] In some specific embodiments, a sensor component 5 is further included, which includes a sensed member 51 located on the side of the carrier component 2 facing the base 1 and a sensing member 51 located on the side of the base 1 facing the carrier component 2; the sensing member 51 is used to measure the lifting height of the carrier component 2 by sensing the position of the sensed member 51.

[0042] In a specific embodiment, the sensed member 52 is arranged on the side of the guide plate 22 facing the guide column 12, and the sensing member 51 is arranged on the side of the guide column 12 facing the guide plate 22. There may be multiple sensed members 52 and sensing members 51. For example, sensing members 51 are respectively arranged at different heights along the first direction on the guide column 12. When the lifting assembly 3 drives the object-carrying assembly 2 to lift, different sensing members 51 on the guide column 12 sense the existence of the sensed member 52 on the guide plate 22 at different heights, thereby measuring the lifting height of the object-carrying assembly 2.

[0043] Furthermore, the sensing element 52 and the sensing element 51 may be respectively arranged on the base frame 11 and the fork 21, and the lifting height of the object-carrying component 2 may be measured by radar ranging or infrared ranging.

[0044] In some specific embodiments, the plane where the chassis 11 is located and the plane where the forks 21 are located are parallel to each other. Figure 4 As shown. Among them, the lowest height of the fork 21 is lower than or equal to the height of the plane where the chassis 11 is located, and the highest height of the fork 21 is lower than or equal to the height of the highest point of the guide column 12. It should be noted that this embodiment does not specifically limit the height of the guide column 12 and the lifting rod 32. In actual applications, the user can adjust the height of the guide column 12 and / or the lifting rod 32 according to actual conditions to adapt to actual needs.

[0045] In some specific embodiments, the driving mechanism 31 includes an oil pump and an oil pipe connected to each other, and the oil pump is connected to the lifting rod 32 through the oil pipe.

[0046] In some specific embodiments, the lifting rod 32 includes a hydraulic cylinder.

[0047] In actual application, the lifting rod 32 rises or falls under the drive of the driving mechanism 31, and the transverse rod 33 connected to the lifting rod 32 and the rotating members 34 on both sides of the transverse rod 33 also rise or fall with the lifting rod 32. Since one end of the chain 35 is fixedly connected to the base 1 through the weight detection member 4, and the other end is connected to the object-carrying assembly 2, the chain 35 moves relative to the rotating member 34 under the influence of the lifting and lowering of the lifting rod 32. When the lifting rod 32 rises along the first direction, the length of the chain 35 from the rotating member 34 to the side of the base 1 increases, and the length of the chain 35 from the rotating member 34 to the side of the object-carrying assembly 2 decreases, so that the chain 35 can further pull the object-carrying assembly 2 to rise along the first direction.

[0048] During the ascending process of the load-carrying assembly 2, since both ends of the guide plate 22 of the load-carrying assembly 2 are movably connected to the guide column 12 of the base 1 through the guide member 221, the guide member 221 slides upward along the first direction on the guide column 12, further driving the guide plate 22 and the fork 21 to move upward along the first direction. When the fork 21 carries goods, the weight detection member 4 pulls the load-carrying assembly 2 through the chain 35 to detect the change in pressure on the load-carrying assembly 2, and can further detect the weight of the goods carried on the fork 21.

[0049] In some specific embodiments, the weight detection component 4 and the sensor component 5 can be connected to an external host computer for communication, and the weight detection component 4 and the sensor component 5 can upload the obtained weight data and lifting height data to the external host computer. The user can also further set the lifting height of the lifting component 3 and further set the weight threshold of the items that the fork 21 can carry through the external host computer, so that in the process of remotely controlling the lifting device to lift and obtain goods, the amount of goods that the loading component 2 obtains each time can be effectively controlled.

[0050] This embodiment provides a weighable lifting device, including a base, a load-carrying component, a lifting component and a weight detection component. By setting the specific structure of the lifting component and detecting the weight of the items in the load-carrying component through the weight detection component, the weight of the goods can be verified while the goods are being transported, which can save the additional weighing steps, effectively improve the work efficiency in the logistics process, and reduce the waste of human resources. Furthermore, the specific lifting height of the load-carrying component during the lifting process can also be detected at the same time, providing more reference data for the cargo transportation work, making the logistics work more efficient and smooth.

[0051] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
