Description

Technical Field

[0001] The present application relates to the technical field of construction equipment, and in particular to a remote measuring device for a spreader. Background Art

[0002] Shore-to-shore container cranes, also known as quay cranes or bridge cranes, are specialized equipment used for loading and unloading container ships at container terminals and are typically installed on the shore of port terminals. Spreaders are key components of bridge crane equipment and are used to directly grab containers. Currently, there is a telescopic spreader whose length can be automatically adjusted by hydraulically driving a telescopic chain to accommodate the loading and unloading needs of containers of different specifications. Placing the spreader in each telescopic position requires the coordination of multiple mechanisms. During the frequent maintenance and servicing of the spreader, the data from each mechanism must be meticulously measured and recorded, and the required effective length can then be adjusted based on the spreader's measured values. Therefore, the accuracy of the measured values ​​will completely affect the spreader's operating efficiency.

[0003] In related technologies, refined measurement still relies on traditional belt ruler methods, combining belt ruler measurements with data recorded during routine maintenance operations to improve the refinement of the entire process, from actual operations to data recording. Belt ruler measurement typically requires two workers to align the ends of the belt ruler with the edge of the spreader mechanism to be measured. A third worker, after powering off the spreader at the switch, runs to the location of the mechanism to be measured, reads and records the value, and then runs back to the switch to power it on.

[0004] The aforementioned belt-measurement method is subject to certain visual errors and inherent stretching errors, resulting in significant errors in the actual spreader measurement. Accumulating errors in spreader maintenance records can ultimately lead to a surge in equipment failure rates. Utility Model Content

[0005] In order to improve the accuracy of the spreader measurement value and reduce the failure rate, the present application provides a spreader remote measurement device.

[0006] The present application provides a remote measuring device for a spreader that adopts the following technical solution:

[0007] A remote measuring device for a spreader includes a laser rangefinder arranged on a spreader base, a laser receiving board detachably connected to the telescopic end of the spreader, and a remote control console electrically connected to both the laser rangefinder and the telescopic end of the spreader. A mounting bracket for mounting the laser rangefinder is provided on the spreader base, and the mounting bracket and the laser receiving board are on the same horizontal line.

[0008] By adopting the above technical solution, non-contact measurement is performed using a laser rangefinder and a laser receiving board, avoiding the visual errors and belt stretching errors that exist in traditional belt ruler measurements, thereby improving the accuracy of the sling measurement value and ensuring the accuracy of the measurement data. The laser receiving board is detachably connected to the telescopic end of the sling, which is convenient for installation, disassembly, and replacement. It can be temporarily and quickly installed during equipment maintenance and is easy to disassemble at the end of maintenance without affecting the normal use of the sling. At the same time, the laser rangefinder is installed on the mounting bracket on the sling base, and its position is fixed and stable, ensuring the reliability and consistency of the measurement. The staff can operate it through the remote control console without having to frequently run between the sling switch position and the mechanism to be measured, reducing labor costs and time consumption and improving measurement efficiency.

[0009] Furthermore, the mounting frame includes a shell for placing the laser rangefinder and a mounting plate for mounting on a sling base. The shell has a receiving cavity for placing the laser rangefinder. One side of the shell is provided with a socket for inserting the laser rangefinder and for emitting laser light. The mounting plate is arranged on a side of the shell away from the socket.

[0010] By adopting the above technical solution, the shell is installed on the base of the sling through the mounting plate, providing a placement platform for the laser rangefinder. The housing cavity of the shell provides protection for the laser rangefinder to prevent collision during operation. When the laser rangefinder needs to be repaired or replaced, it only needs to be removed from the shell without the need for complicated operations on the entire mounting frame. The socket enables the laser rangefinder to maintain a fixed position and angle when inserted into the shell, thereby ensuring that the laser can be accurately emitted and received by the laser receiving board, reducing measurement errors caused by unstable position or angle deviation of the laser rangefinder.

[0011] Furthermore, a window for observing the laser rangefinder screen is provided on the side wall of the shell.

[0012] By adopting this technical solution, the viewing window allows workers to observe the laser rangefinder's screen directly through the window without opening the housing, providing real-time information on the measurement status, results, and operating conditions, ensuring smooth measurement. If the laser rangefinder malfunctions or anomalies occur, observing the screen through the window allows for quick identification of the problem. This facilitates rapid troubleshooting, reduces equipment downtime, and improves equipment utilization.

[0013] Furthermore, a clearance groove for taking out the laser rangefinder is provided on the shell, and the clearance groove is located on the side of the shell where the socket is provided and is symmetrically provided on the front and back sides of the shell.

[0014] By adopting the above technical solution, the groove is located on the side of the housing where the socket is provided and is symmetrically provided on the front and rear sides of the housing, providing sufficient space for the operator's hands or tools to enter, making it easy to remove the laser rangefinder from the housing, thereby simplifying the installation and removal process and avoiding damage to the laser rangefinder or the housing. The groove is located on the side of the housing where the socket is provided and is symmetrically provided on the front and rear sides of the housing, providing sufficient space for the operator's hands or tools to enter, making it easy to remove the laser rangefinder from the housing, thereby simplifying the installation and removal process and avoiding damage to the laser rangefinder or the housing.

[0015] Furthermore, the shell is fixedly connected to an extension plate on the outer wall away from the socket, the mounting plate is vertically fixedly connected to the top side of the extension plate, and a connecting piece for connecting to the sling base is vertically penetrated on the mounting plate.

[0016] By adopting this technical solution, an extension plate is fixed to the outer wall of the housing away from the socket, and the mounting plate is fixed perpendicularly to the top of the extension plate. This arrangement increases the overall rigidity and stability of the mounting structure. The extension plate acts as a transitional component, effectively dispersing the force transmitted from the mounting plate to the housing, reducing stress concentration on the housing. A connector extends perpendicularly through the mounting plate and connects to the base of the spreader, ensuring a secure installation of the laser rangefinder.

[0017] Furthermore, an adjusting nut for adjusting the distance between the mounting plate and the sling is threadedly connected to the connecting piece.

[0018] By adopting the above technical solution, the adjustment nut allows the distance between the mounting plate and the sling base to be fine-tuned according to actual needs. By rotating the adjustment nut, the position of the mounting plate can be adjusted without the need for complicated disassembly and reinstallation processes, thereby improving flexibility and ensuring that the laser rangefinder can be accurately installed in the required position, thereby improving measurement accuracy.

[0019] Furthermore, a gap is provided on the laser receiving plate to allow space for the sling base.

[0020] By adopting the above technical solution, the setting of the clearance gap avoids possible interference between the laser receiving plate and the spreader base, so that when the spreader base may be in different positions during operation, it can still accurately receive the laser signal emitted by the laser rangefinder. There is no obstruction or interference, and the laser signal can reach the receiving plate directly and stably, thereby improving the accuracy and reliability of the measurement.

[0021] Furthermore, the laser receiving plate is vertically fixedly connected to a connecting plate for connecting to the telescopic end of the sling at a position adjacent to the clearance gap.

[0022] By adopting the above technical solution, the connecting plate is fixed vertically to the laser receiving plate and connected to the telescopic end of the spreader, which enhances the stability and reliability of the connection and ensures that the laser receiving plate can maintain a stable position and angle during the movement of the spreader, thereby improving the accuracy of the measurement.

[0023] Furthermore, the remote control console includes a control cabinet and a control console surface provided on the control cabinet, the control console surface having a plurality of buttons for controlling the laser rangefinder and the spreader, the control cabinet being provided with control modules corresponding one-to-one to the various mechanisms of the spreader and the laser rangefinder, the control module being electrically connected to the spreader, and the control module being signal-connected to the laser rangefinder.

[0024] By adopting this technical solution, the buttons for controlling the laser rangefinder and spreader are centralized on the control panel, providing operators with a clear overview of all control options, enabling quick selection and operation. Centralized control improves operational efficiency and reduces the possibility of misoperation. The control cabinet houses control modules corresponding to each spreader mechanism, achieving modular functional division and facilitating independent control of each control module. This facilitates debugging, maintenance, and replacement, and eliminates the need for operators to repeatedly power on and off, improving operational efficiency.

[0025] Furthermore, a voice broadcast module electrically connected to the control module is provided in the cabinet, and a signal connection is provided between the voice broadcast module and the laser rangefinder.

[0026] By adopting the above technical solution, the voice broadcast module receives the measurement data of the laser rangefinder in real time and broadcasts it in voice form. The operator does not need to stare at the display screen or control panel all the time to obtain and record the measurement results in time, which improves the convenience and efficiency of operation.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Non-contact measurement using a laser rangefinder and a laser receiver board avoids the visual and stretching errors found in traditional belt ruler measurements, improving the accuracy of the spreader's measurements and ensuring the accuracy of the measurement data. The laser receiver board is detachably connected to the spreader's telescopic end, facilitating installation, removal, and replacement while ensuring measurement stability and consistency. The laser rangefinder is mounted on a stable mounting bracket on the spreader base, and precise position adjustment is achieved through adjusting nuts, further ensuring measurement reliability. The housing design not only protects the laser rangefinder from collisions during operation, but also allows operators to observe the measurement status in real time through the window design, promptly identifying and addressing problems, reducing measurement errors and downtime.

[0029] 2. The remote control console eliminates the need for operators to frequently run between the spreader switch position and the structure to be measured. The laser rangefinder and spreader can be centrally controlled through buttons on the console panel, improving operational efficiency and reducing labor costs and time consumption. The introduction of the voice broadcast module allows operators to hear the measurement results in real time without having to constantly pay attention to the display screen, further improving the convenience and efficiency of operation.

[0030] 3. The housing and extension plate enhance the overall rigidity and stability of the mounting structure, effectively dispersing the force transmitted from the mounting plate to the housing, reducing stress concentration on the housing and improving system stability. The fixed position and angle of the laser rangefinder ensure that the laser signal is accurately emitted and received, reducing measurement errors caused by unstable device position or angular deviation.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-4 And embodiments, the present application is further described in detail.

[0037] The present application discloses a remote measuring device for a spreader. Words such as "upper" and "lower" used to express positional relationships in this embodiment are determined with reference to the placement and installation position of the remote measuring device for a spreader in normal use.

[0038] Reference Figure 1The spreader remote measurement device includes a laser rangefinder 1, a laser receiving board 2, a remote control console 3 and a mounting bracket 4 for mounting the laser rangefinder 1 on a spreader base 0.

[0039] Reference Figure 1 and Figure 2 The mounting frame 4 includes a housing 41, a mounting plate 42, an extension plate 43, and a connector 44. The housing 41 has a housing 411 for accommodating the laser rangefinder 1. In this embodiment, there are preferably two extension plates 43, which are arranged parallel to each other and are both vertically fixedly connected to one side of the housing 41. The mounting plate 42 is vertically fixedly connected to the top sides of the two extension plates 43. In this embodiment, the fixed connection between the extension plates 43 and the housing 41, and between the mounting plate 42 and the extension plates 43, is preferably a relatively stable welding method.

[0040] The top surface of the mounting plate 42 is flush with the top surface of the housing 41. In this embodiment, the connectors 44 are relatively long bolts. Preferably, there are two connectors 44, each of which passes vertically through the bottom surface of the mounting plate 42 and is fixedly connected to the bottom surface of the sling base 0. An adjusting nut 441 is sleeved and threaded onto each connector 44 for adjusting the distance between the mounting plate 42 and the bottom surface of the base.

[0041] On the side of the housing 41 facing away from the extension plate 43, a socket 412 is provided for inserting the laser rangefinder 1. Once inserted into the housing 41, the end of the laser rangefinder 1 that emits the laser beam is positioned on the side of the socket 412, allowing the laser beam to be received by the laser receiving board 2. A window 413 is provided on the front side of the housing 41 for viewing the screen of the laser rangefinder 1. Two symmetrically positioned clearance grooves 414 are provided on the front and rear side panels of the housing 41, adjacent to the side where the socket 412 is located. This allows the operator to grasp and remove the laser rangefinder 1 through the clearance grooves 414.

[0042] Reference Figure 1 and Figure 3 The top side of the laser receiving plate 2 features a clearance notch 21 for the spreader's telescopic end 01. The laser receiving plate 2 is vertically positioned adjacent to the clearance notch 21 and integrally connected to a connecting plate 22. This threaded connection allows for a convenient temporary installation of the laser receiving plate 2 when the spreader requires maintenance, and also facilitates removal after maintenance, preventing disruption to the spreader's operation.

[0043] Reference Figure 1 and Figure 4The remote control console 3 includes a control cabinet 31 and a control console surface 32 integrally connected to the upper portion of the control cabinet 31. The control cabinet 31 has a cabinet door that can be opened and closed, and universal casters are provided below the control cabinet 31 for easy movement.

[0044] The control panel 32 is equipped with several buttons 321. The control cabinet 31 houses control modules 311 corresponding to each mechanism of the spreader. The control modules 311 are electrically connected to each mechanism and each button 321. A signal connection is also established between the control module 311 and the laser rangefinder 1. The cabinet also houses a voice broadcast module 312, which in this embodiment is preferably a Bluetooth speaker. This module is signal-connected to the laser rangefinder 1. Operators can control the spreader using each button 321, eliminating the need to repeatedly power on and off each mechanism. The buttons 321 also allow operators to control the laser rangefinder 1. Test data from the laser rangefinder 1 is directly output as audio via the voice broadcast module 312, making it easier to record.

[0045] The implementation principle of a remote measurement device for a sling according to an embodiment of the present application is as follows: a laser rangefinder 1 is securely mounted on a sling base 0 via a mounting bracket 4. The mounting bracket 4 consists of a housing 41, a mounting plate 42, an extension plate 43, and a connector 44. The housing 41 provides a housing 411 for the laser rangefinder 1. The mounting plate 42 is connected to the housing 41 via the extension plate 43 and secured to the sling base 0 via connectors 44 (e.g., bolts) and adjustment nuts 441, ensuring the stability and positional accuracy of the laser rangefinder 1 during operation. The laser receiving plate 2 is threadedly connected to the telescopic end 01 of the sling via a connecting plate 22. The connecting plate 22 is located adjacent to a clearance notch 21 on the laser receiving plate 2, facilitating temporary installation and removal when needed. The laser rangefinder 1 emits a laser beam toward the laser receiving plate 2, employing a non-contact measurement method that avoids the visual and stretching errors associated with traditional belt ruler measurements, thereby improving measurement accuracy.

[0046] The remote control console 3 consists of a control cabinet 31 and a control panel 32. The control cabinet 31 houses control modules 311 corresponding to each spreader mechanism, as well as a voice announcement module 312 (e.g., a Bluetooth speaker) connected to the laser rangefinder 1 signal. The operator can control the spreader and laser rangefinder 1 using buttons 321 on the control panel 32, avoiding frequent movement between the spreader's on / off position and the mechanism being tested. Electrical connections between the control module 311, the spreader mechanisms, and the buttons 321 ensure accurate command transmission and execution. Test data from the laser rangefinder 1 is transmitted to the voice announcement module 312 via a signal connection and output as audio, allowing the operator to record and understand measurement results in real time.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
