Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a hoisting structure for weighing. Background Technology

[0002] Existing lifting frame structures typically involve bolting hooks at both ends to the sides of the main frame body. One end of a guide rod is connected to the main frame body, and the other end is connected to a traveling trolley. One end of the tension / compression sensor is locked to the main frame body, and the other end is locked to a floating joint, which is directly connected to the cylinder of the traveling trolley. When the main frame body moves downwards, it grabs the material (such as a ton bag) through the hooks at both ends. When the material is lifted upwards, because the tension / compression sensor is directly connected to the traveling trolley via the floating joint, it is simultaneously affected by the gravity of the material below and the frictional force of the four guide rods above. Furthermore, the sliding friction of the guide rods changes irregularly, resulting in significant differences in the dynamic measurement of the material weight, making accurate weight measurement impossible. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and provide a weighing hanger structure with high measurement accuracy and high safety.

[0004] The technical solution of this utility model is: a hanging frame structure for weighing, including a hanging frame body connected to an external mechanism, a hook locking body, a tension / compression sensor and a hook device; the tension / compression sensor is locked between the hanging frame body and the hook locking body; the hook device is symmetrically locked on both sides of the hook locking body.

[0005] Furthermore, the main body of the hanger is connected to an external mechanism via guide rods and / or floating joints.

[0006] Furthermore, the main body of the hanger includes a guide rod, a guide rod connecting plate, and a hanger auxiliary body; the main body of the hanger is connected to an external mechanism through the guide rod; the lower end of the guide rod is connected to the guide rod connecting plate, and the guide rod and the guide rod connecting plate are integrally locked onto the hanger auxiliary body.

[0007] Furthermore, a fall arrestor plate is connected to the upper end of the guide rod, and the fall arrestor plate is locked to the guide rod by the first bolt.

[0008] Furthermore, the lower end of the guide rod is locked to the guide rod connecting plate in the reverse direction by the second bolt, and the guide rod and the guide rod connecting plate are locked to the hanger auxiliary body by the third bolt.

[0009] Furthermore, the floating joint is movably connected to the auxiliary body of the hanger, and the main body of the hanger is connected to an external mechanism through a guide rod and the floating joint.

[0010] Furthermore, the number of guide rods is 2 to 6, symmetrically arranged on the hanger auxiliary body; the hanger auxiliary body is provided with a connecting cavity, which is movably connected to at least one floating joint.

[0011] Furthermore, after the lower end of the floating joint extends into the connecting cavity, its end is connected to the first limiting member; the floating joint is provided with a second limiting member near the upper surface of the connecting cavity, and the second limiting member has a gap with the upper surface of the connecting cavity. Through the constraint of the first limiting member and the second limiting member, the floating joint can achieve a certain range of free movement in the connecting cavity.

[0012] Furthermore, the number of tension and compression sensors is 1 to 4, and the upper part of the tension and compression sensors is screwed to the hanger auxiliary body; the hook locking body is provided with a single-ended connector at the position corresponding to the tension and compression sensors, and a locking nut is provided on the thread of the single-ended connector. The upper end of the single-ended connector is inserted into the connection hole at the lower part of the tension and compression sensor, and the tension and compression sensor is locked to the single-ended connector by the locking nut.

[0013] Furthermore, the connecting hole is a threaded hole. After the upper end of the single-head connector is screwed into the threaded hole, the height can be adjusted along the threaded hole and locked by the locking nut. The threaded hole of the tension / compression sensor and the locking nut form a double-nut anti-loosening structure.

[0014] Furthermore, the tension / compression sensor is an S-type tension / compression sensor.

[0015] The beneficial effects of this utility model are:

[0016] (1) By adding a hook locking body and connecting the tension and pressure sensor between the hook locking body and the hanger body, since the tension and pressure sensor is not directly connected to the floating joint and the traveling trolley, the sliding friction between the guide rod and the external mechanism is an internal force. When the hanger body moves up and down, the sliding friction between the guide rod and the external mechanism can avoid the influence of the tension and pressure sensor on the tension and pressure sensor. The tension and pressure sensor is only subjected to the tension of the hanger body, the weight of the hook device itself and the weight of the material. Since the hanger body and the external mechanism are a whole, the operation can be more stable. The weight of the hook device remains constant. At this time, the tension and pressure sensor can accurately measure the weight of the material, greatly improving the measurement accuracy.

[0017] (2) A fall arrestor is provided at the top of the guide rod. When the external mechanism fails, the fall arrestor can prevent the hanger mechanism from falling and causing an accident; and the tension and compression sensor is connected to the single-head connector through the locking nut, so that the tension and compression sensor and the locking nut form a double nut anti-loosening and the height can be adjusted.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 As shown: A weighing hanger structure includes a hanger body 1 connected to an external mechanism, a hook locking body 2, a tension / compression sensor 3, and a hook device 4; the hanger body 1 is connected to the hook locking body 2 via the tension / compression sensor 3. There are two hook devices 4, symmetrically locked onto both sides of the hook locking body 2.

[0028] like Figure 2 and Figure 3As shown: In this embodiment, the main body 1 of the hanger includes guide rods 11, guide rod connecting plates 12, and hanger auxiliary body 13. There are four guide rods 11, symmetrically arranged at the four corners of the hanger auxiliary body 13. Each guide rod 11 has a fall arrestor plate 14 connected to its upper end, and the fall arrestor plate 14 is locked to the guide rod 11 by a first bolt 15. The lower end of the guide rod 11 is locked to the guide rod connecting plate 12 by a second bolt 16, and the guide rod 11 and guide rod connecting plate 12 are then locked together to the hanger auxiliary body 13 by a third bolt 17. Because the fall arrestor plate is locked to the guide rod, and the guide rod is inserted into the linear bearing of the traveling trolley and extends and retracts with the cylinder of the traveling trolley, when the external mechanism malfunctions (such as cylinder failure), the fall arrestor plate will lock onto the outside of the linear bearing, preventing the guide rod from falling off and thus avoiding an accident caused by the main body of the hanger falling.

[0029] Preferably, the lower end of the guide rod 11 has a threaded hole at its center, and the second bolt 16 passes through the guide rod connecting plate 12 and is screwed into the threaded hole of the guide rod 11 for fixation. Each of the four corners of the hanger auxiliary body 13 has a connecting seat 131 for locking with the corresponding guide rod connecting plate, and multiple third bolts 17 pass through the guide rod connecting plate 12 and are screwed to the connecting seat 131 for fixation. On the one hand, the third bolts 17 prevent the second bolt 16 from falling off; on the other hand, the combination of the second bolt 16 and the third bolts 17 locks the guide rod 11 and the guide rod connecting plate 12 together onto the hanger auxiliary body 13, greatly improving the stability of the hanger body 1.

[0030] More preferably, both the guide rod connecting plate 12 and the connecting seat 131 of the hanger auxiliary body are cylindrical. The connecting seat 131 can be welded to the hanger auxiliary body 13 or integrally formed with the hanger auxiliary body.

[0031] More preferably, the hanger auxiliary body 13 includes a plate, with baffles around the perimeter except for the connecting seat, forming a groove structure. A connecting cavity 132 is provided in the center of the groove along the length of the plate, and the connecting cavity 132 is movably connected to at least one floating joint 18. After the lower end of the floating joint 18 extends into the connecting cavity 132, its end is connected to a limiting plate 181 to prevent the floating joint 18 from detaching from the connecting cavity 132. The connecting cavity 132 is designed with an inverted U-shape, and the floating joint 18 has a nut 182 near the upper surface of the connecting cavity 132. A certain gap is left between the nut 182 and the upper surface of the connecting cavity. Through the constraint of the nut 182 and the limiting plate 181, the floating joint 18 can move freely within a certain range within the connecting cavity 132. The upper end of the floating joint 18 can be connected to the cylinder piston rod of the traveling trolley to compensate for installation eccentricity.

[0032] Furthermore, the main body of the hanger 1 is connected to an external mechanism via a floating joint 18 and a guide rod 11.

[0033] like Figure 4 As shown: In this embodiment, the number of tension / compression sensors 3 is 1 to 4, preferably four, symmetrically arranged near the corners of the bottom surface of the hanger auxiliary body 13. The upper part of the tension / compression sensor 3 is locked to the hanger auxiliary body 13 via a floating washer 31 and a fourth bolt 32, and the lower part is locked to the hook locking body 2 via a locking nut 22. Specifically, the fourth bolt 32 passes through the plate of the hanger auxiliary body 13, the floating washer 31, and is threadedly connected to the upper part of the tension / compression sensor 3. The hook locking body 2 has a single-ended connector 21 welded at the position corresponding to the tension / compression sensor 3. The single-ended connector 21 has a locking nut 22 on its thread. The upper end of the single-ended connector 21 is inserted into the connection hole at the lower part of the tension / compression sensor 3, and the tension / compression sensor 3 is locked to the single-ended connector 21 by the locking nut 22.

[0034] Preferably, the tension / compression sensor 3 is an S-type tension / compression sensor. The connection hole on the lower plane of the tension / compression sensor 3 is a threaded hole, so that after the upper end of the single-ended connector 21 is screwed into the threaded hole, the height can be adjusted along the threaded hole, allowing the single-ended connector 21 to be screwed in or out of the threaded hole, and finally locked by the locking nut 22. In this way, the height between the tension / compression sensor 3 and the hook locking body 2 can be adjusted according to different needs. In this embodiment, the tension / compression sensor 3 is connected to the single-ended connector 21 by the locking nut 22. Since the tension / compression sensor 3 has its own thread, the addition of the locking nut 22 forms a double-nut anti-loosening structure. When the locking nut 22 is tightened, an axial force is generated between it and the thread of the tension / compression sensor 3, which increases the friction between the threads of the single-ended connector 21 and the threads of the tension / compression sensor and the locking nut, thus preventing loosening.

[0035] In this embodiment, two hook devices 4 are symmetrically locked to both sides of the hook locking body 2 by bolts. The structure of the hook device 4 is already existing technology, and can be found in the hook device disclosed in CN117486062A, so it will not be described in detail here.

[0036] The working principle of this embodiment is as follows: the main body 1 of the hanger can move up and down and / or horizontally under the drive of the external mechanism, and different settings can be made according to the needs; when it moves to the target position, the material is clamped by the hook device 4. During the movement of the main body 1 of the hanger, for example, during the upward movement, the tension and pressure sensor 3 will detect the weight of the material. At this time, the tension and pressure sensor 3 will be subjected to the tension of the main body 1 of the hanger, the weight of the hook device 4 itself and the weight of the material. Since the main body 1 of the hanger and the external mechanism are a whole, the operation can be more stable. The weight of the hook device 4 remains constant. At this time, the tension and pressure sensor 3 can accurately measure the weight of the material.

[0037] In summary, this embodiment has the following advantages:

[0038] (1) By locking the hook devices at both ends to the hook locking body, the hook locking body is connected to the lower part of the tension and pressure sensor, and the upper part of the tension and pressure sensor is locked to the hanger body. The hanger body is connected to the external mechanism through the floating joint and the guide rod. At this time, the hanger body and the external mechanism form an integral structure. The sliding friction between the guide rod and the external mechanism is the internal force. When the hook device clamps the material and moves upward, the tension and pressure sensor is subjected to the tension of the hanger body, the weight of the hook device itself and the weight of the material. Since the hanger body and the external mechanism are an integral whole, the operation can be more stable. The weight of the hook device remains constant. At this time, the tension and pressure sensor can accurately measure the weight of the material, which greatly improves the measurement accuracy.

[0039] (2) The main body of the hanger is integrated with the external mechanism through the floating joint and guide rod. The lower part is connected to the tension and pressure sensor through bolts. When the main body of the hanger moves up and down, the sliding friction between the guide rod and the external mechanism can avoid the influence of the tension and pressure sensor.

[0040] (3) A fall arrestor is provided at the top of the guide rod. When the external mechanism fails, the fall arrestor can prevent the hanger mechanism from falling and causing an accident; and the tension and compression sensor is connected to the single-head connector through the locking nut, so that the tension and compression sensor and the locking nut form a double nut anti-loosening and the height can be adjusted.

[0041] Furthermore, the term "connection" should be interpreted broadly, for example, it can include fixed connections, detachable connections, or integral connections; it can include direct connections or indirect connections through an intermediate medium, and it can also include internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
