Description

Technical Field

[0001] The utility model relates to the technical field of weighing equipment, in particular to a lifting weighing and transporting equipment. Background Art

[0002] Weighing-type transfer equipment consists of a weighing unit and a load-bearing unit. The load-bearing unit is used to hold items to be transferred, and the weighing unit is located at the bottom of the load-bearing unit and can be used to weigh items during storage and transfer. In the prior art, the weighing unit of weighing-type transfer equipment typically uses a load cell, which offers advantages such as high weighing accuracy and easy control. However, the load-bearing unit is directly mounted on the load cell, and the sensing end of the load cell is constantly in contact with the bottom surface of the load cell, which is always under stress. This can lead to fatigue of the load cell, resulting in reduced weighing accuracy and shortened service life. Utility Model Content

[0007] A positioning plate is provided at the bottom of the vehicle body, and a guide groove is provided on the positioning plate to cooperate with the connecting column;

[0008] The bottom of the vehicle body is provided with a support sleeve for cooperating with the sensing end of the weighing sensor;

[0009] When the lifting mechanism is in the first position, a first distance is formed between the mounting plate and the positioning plate, and a gap is formed between the top surface of the sensing end of the weighing sensor and the bottom surface of the support sleeve. At this time, the vehicle body is in a non-weighing state;

[0010] When the lifting mechanism is in the second position, a second distance is formed between the mounting plate and the positioning plate, and the top surface of the sensing end of the weighing sensor is in contact with the bottom surface of the support sleeve. At this time, the vehicle body is in a weighing state;

[0011] The first position is lower than the second position, and the first distance is greater than the second distance.

[0012] Further technical solutions are:

[0013] The structure for the movable cooperation between the frame and the body comprises a guide post arranged on the top of the frame and a guide sleeve arranged on the bottom of the body and cooperating with the guide post.

[0014] The structure of the movable cooperation between the frame and the body includes: a connecting handle, both ends of which are provided with hinged parts for connecting with the frame and the body respectively, and the hinge axis of the hinged part is perpendicular to the guide column.

[0015] The top end of the connecting column extending out of the mounting plate is provided with a limiting portion, and the width of the limiting portion is greater than the width of the guide groove.

[0016] There are multiple weighing sensors distributed at the top four corners of the lifting mechanism.

[0021] The utility model has a reasonable structural design and is easy to operate. The position of the weighing sensor is adjusted by the lifting mechanism to switch the device between weighing and non-weighing states. This avoids the wear and tear caused by the weighing sensor being in constant contact with the vehicle body, ensuring weighing accuracy and extending its service life.

A weighing sensor 14 and a mounting plate 17 are provided on the top of the lifting mechanism 13, and a vertical connecting column 11 is provided on the mounting plate 17;

[0035] See also Figure 3 , a positioning plate 23 is provided at the bottom of the vehicle body 2, and a guide groove 231 is provided on the positioning plate 23 to cooperate with the connecting column 11;

[0036] A support sleeve 21 is provided at the bottom of the vehicle body 2 for cooperating with the sensing end of the weighing sensor 14;

[0037] See also Figures 4 to 8 When the lifting mechanism 13 is in the first position, a first distance is formed between the mounting plate 17 and the positioning plate 23, and a gap 3 is formed between the top surface of the sensing end of the weighing sensor 14 and the bottom surface of the support sleeve 21. At this time, the vehicle body 2 is in a non-weighing state; when the lifting mechanism 13 is in the second position, a second distance is formed between the mounting plate 17 and the positioning plate 23, and the top surface of the sensing end of the weighing sensor 14 is in contact with the bottom surface of the support sleeve 21. At this time, the vehicle body 2 is in a weighing state;

[0038] The first position is lower than the second position, and the first distance is greater than the second distance.

[0039] See also Figure 2 and Figure 3 The structure of the active cooperation between the frame 1 and the body 2 includes a guide post 15 provided on the top of the frame 1 and a guide sleeve 22 provided on the bottom of the body 2 and cooperating with the guide post 15.

[0040] The structure of the movable cooperation between the frame 1 and the body 2 is as follows: it also includes a connecting handle 16, and a hinge part is provided at both ends of the connecting handle for connecting with the frame 1 and the body 2 respectively, and the hinge axis of the hinge part is perpendicular to the guide column 15.

[0041] As a preferred embodiment, a limiting portion 111 is provided at the top end of the connecting column 11 extending out of the mounting plate 17 , and the width of the limiting portion 111 is greater than the width of the guide groove 231 .

[0042] As a preferred embodiment, a plurality of weighing sensors 14 are provided and distributed at the four corners of the top of the lifting mechanism 13 .

[0046] The working principle of this embodiment is further described below:

[0047] The accompanying drawings in the specification are all in the initial state of the matching structure of the vehicle body 2 and the vehicle frame 1. In this state, no weighing is required, the lifting mechanism 13 is in the first position, which is lower, and a first distance is formed between the mounting plate 17 and the positioning plate 23. Figure 8 As shown, the spacing is relatively large, and a gap 3 is formed between the top surface of the sensing end of the weighing sensor 14 and the bottom surface of the support sleeve 21. Figure 6 As shown, at this time, the vehicle body 2 is in a non-weighing state, that is, there is no contact between the bottom of the vehicle body 2 and the sensing end of the weighing sensor 14 in the vehicle frame 1;

[0048] When weighing is required, the lifting mechanism 13 rises upward. During the lifting process, the mounting plate 17 and the connecting column 11 thereon move upward, the distance between the mounting plate 17 and the positioning plate 23 is reduced, and the connecting column 11 moves upward along the guide groove 231 without interference. At the same time, the top surface of the sensing end of the weighing sensor 14 moves upward until it contacts the bottom surface of the support sleeve 21 at the bottom of the vehicle body 2 and lifts it up, and the guide sleeve 22 at the bottom of the vehicle body 2 slides relative to the guide column 15 at the top of the frame 1 to ensure that the vehicle body 2 moves slightly upward, so that the vehicle body 2 and the items carried therein are supported by the lifting mechanism 13. At this time, the lifting mechanism 13 rises to the second position, and the top surface of the sensing end of the weighing sensor 14 of the mounting plate 17 fits into the bottom surface of the support sleeve 21. The weighing sensor 14 can weigh the weight of the items, and the vehicle body 2 is in a weighing state.
