Description

Technical Field

[0001] This utility model relates to the field of intelligent warehousing and transportation equipment technology, specifically to a cantilever stacker crane fork weighing device. Background Technology

[0002] In the metallurgical industry, steel output is one of the important indicators for measuring the production capacity of steel mills. Good steel output process management can effectively improve steel production efficiency and reduce costs. Taking the transformer industry as an example, intelligent warehouses have been widely used in this industry. The operation process is: slitting and coiling on the slitting line - coil storage - coil release - to the cross-cutting line. Coils that are not used on the cross-cutting line still need to be returned and stored again. Currently, the weight detection of coils is set at the slitting and coiling process after storage and at the cross-cutting line when they are returned and stored again. Therefore, weighing devices are added to these two processes to manage the warehouse storage. This process requires each storage docking equipment to have a weighing function, or to add a dedicated weighing device to this process. The process is complex and too costly.

[0003] Therefore, we propose a cantilever stacker fork weighing device to solve the above problems. Utility Model Content

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a cantilever stacker fork weighing device.

[0024] This utility model provides, for example Figure 1-3 The cantilever stacker crane fork weighing device shown includes a connecting assembly and a fork cantilever 1. The fork cantilever 1 is fixedly connected to the connecting assembly. The fork cantilever 1 has two sets of spaced weighing sensors 2 inside, with two weighing sensors in each set. The weighing sensors 2 have a bridge structure (the weighing sensors 2 can also adopt a spoke structure according to the detection requirements). The side of the weighing sensor 2 is provided with a weighing processing assembly 17, which includes a junction box, a transmitter, and a display instrument. The bottom of the weighing sensor 2 is provided with a support block 3. The side and bottom of the support block 3 are respectively connected to a first fixing plate 4 and a second fixing plate 5. The first fixing plate 4 and the second fixing plate 5 are both fixedly connected to the fork cantilever 1. The top of the two weighing sensors 2 are connected to a support plate 6. The upper surface of the support plate 6 is arc-shaped. Multiple connecting bolts 7 are connected between the support plate 6 and the weighing sensor 2. The top of the fork cantilever 1 is fixedly provided with a baffle 16, which contacts and cooperates with the side of the support plate 6.

[0025] In order to reinforce the load cells and ensure the stability of the cantilever weighing system during movement, such as... Figure 1 and Figure 3 As shown, the connecting assembly includes a chassis 11, a base block 12 fixedly mounted on the top of the chassis 11, a support seat 13 fixedly mounted on the top of the base block 12, the support seat 13 fixedly connected to the fork cantilever 1, a first reinforcing plate 14 fixedly mounted inside the support seat 13, and multiple second reinforcing plates 15 fixedly mounted between the support seat 13 and the base block 12. The support plate 6 has through holes 8 through which connecting bolts 7 pass. The lower side of the load cell 2 has connecting holes 9. The connecting holes 9 have threads through which fixing bolts 10 pass. The threaded end of the fixing bolt 10 is screwed and fixed to the support block 3.

[0026] Working principle: During installation, the overall structure is first fixed to the stacker crane body through the connecting components. The chassis 11 serves as the basic support. The bottom block 12 and the support seat 13 are connected to the top of the chassis 11 in sequence. The first reinforcing plate 14 inside the support seat 13 and the second reinforcing plate 15 between the support seat 13 and the bottom block 12 can enhance the overall rigidity of the connecting components and ensure that the fork arm 1 does not shake or deform when picking up the coil. After the fork arm 1 and the support seat 13 are fixed, the overall installation and fixing of the device is completed.

[0027] The bottom of the load cell 2 is placed on the support block 3. The support block 3 is fixed to the side wall of the fork arm 1 by the first fixing plate 4 on the side and the second fixing plate 5 at the bottom is fixed to the bottom of the fork arm 1, realizing the bidirectional limiting of the support block 3. At the same time, a fixing bolt 10 is inserted into the connecting hole 9 at the lower side of the load cell 2. The threaded end of the fixing bolt 10 is screwed to the support block 3, which tightly fixes the load cell 2 on the support block 3 to prevent the sensor from shifting during weighing and affecting the accuracy. The tops of the two load cells 2 are connected to the support plate 6 by the connecting bolt 7. The upper surface of the support plate 6 is arc-shaped, which can fit the inner arc of the coil to ensure the stable placement of the coil.

[0028] When the stacker crane performs the coil loading operation, the fork arm 1 drives the support plate 6 to extend into the inner circle of the coil. The weight of the coil acts entirely on the arc-shaped support plate 6, which evenly transmits the weight to multiple weighing sensors 2 below. After being subjected to pressure, the weighing sensors 2 convert the mechanical signal into an electrical signal and transmit it to the weighing processing component 17 on the side. The junction box summarizes and performs preliminary processing on the electrical signals from the two sensors. The transmitter converts the processed signal into a standard electrical signal, and finally, the display instrument displays the coil weight data in real time (this detection method is a publicly available method in the prior art, so it will not be described in detail). The staff can intuitively read the weight information, realizing the synchronous completion of coil loading and weighing detection.

[0029] During this process, the baffle 16 at the top of the fork arm 1 contacts and cooperates with the side of the support plate 6, which can prevent the coil from shifting to one side during the fork picking and transfer process, and avoid the coil from slipping or causing weighing errors due to uneven force. The reinforced structure of the connecting component and the multiple fixing structure of the weighing sensor 2 together ensure the stability of the device during dynamic transfer.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
