Description

Technical Field

[0001] This utility model relates to the field of construction machinery technology, specifically to a drum device and a quay crane. Background Technology

[0002] When the hoisting, traction, and pitching mechanisms of quay cranes are in operation, factors such as damaged rope guides, drum wear, installation deviations, or improper operation may cause the wire ropes to become disordered, resulting in tangled wire ropes. Tangled wire ropes cause abnormal friction between the wire ropes and with the drum, accelerating wear, causing wire breakage or even breakage. In severe cases, this can lead to safety accidents such as falling heavy objects, while also affecting the normal operation of the equipment, reducing work efficiency, and posing significant safety hazards.

[0003] Currently, the existing method for detecting tangled wire ropes is laser detection. This involves placing a laser emitter and receiver on one side of the winch drum to form a detection beam parallel to the drum's axis. When the wire rope obstructs the detection beam, it indicates that the rope is tangled. However, since the working environment of quay cranes and other construction machinery is usually harsh, the wire rope can easily throw oil and other impurities onto the surface of the detection components during operation, preventing the components from forming a detection beam properly and resulting in poor detection reliability. Utility Model Content

[0004] In view of this, the present invention provides a drum device and a quay crane to solve the problem of poor reliability of existing drum rope tangling detection structures.

[0006] Beneficial effects: By installing a protective cover on the detection bracket used to install the detection components, the first detection component can emit a light beam through the detection port, and the light beam can enter the second detection component through the detection port. The protective cover can not only ensure the formation of the detection optical path, but also effectively protect the first and second detection components, preventing damage to the detection components or obstruction of the emission port after oil or other impurities splash onto the detection components. This can effectively improve the stability of the tangled rope detection of the detection component and effectively solve the problem of poor detection reliability of the existing tangled rope detection structure of the drum.

[0016] Beneficial effects: By arranging the first and second detection components in this manner, the tangled rope condition in certain areas can be detected more effectively, and the detection distance at different positions can be changed. At the same time, the first and second detection components can be arranged more flexibly.

[0017] In one alternative embodiment, the protective cover has a mounting cavity, the protective cover is detachably connected to the detection bracket, and the first detection element and the second detection element are disposed in the corresponding mounting cavity.

[0018] Beneficial effects: This type of test component arrangement allows the first and second test components to form an integrated structure with their corresponding protective covers.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] In related technologies, when steel wire ropes are in operation, they can easily throw oil and other impurities onto the surface of the detection components. When the oil and other impurities flow to the emission port of the detection components, they will block the detection beam. At this time, even if there is no rope tangling, a rope tangling warning will be generated, which may lead to false alarms and affect the normal operation of the quay crane.

[0029] The following is combined Figures 1 to 10 The following describes embodiments of the present invention.

[0030] According to an embodiment of the present invention, a winding device is provided, comprising: a winding frame, a winding 1, and a detection component, wherein the winding 1 is rotatably disposed on the winding frame along its own axis; the detection component comprises a first detection element 2, a second detection element 3, and two detection brackets 4.

[0031] A detection optical path 5 is formed between the first detection element 2 and the second detection element 3. The detection bracket 4 is disposed on the roll frame and has a mounting position 401 for mounting the first detection element 2 or the second detection element 3. The mounting position 401 is located on one side of the radial direction of the roll 1. A protective cover 402 is provided on the mounting position 401. The protective cover 402 has a detection port 403 for the light beam to pass through.

[0032] In the roll device of this embodiment, a protective cover 402 is provided on the detection bracket 4 for mounting the detection components. The first detection component 2 can emit a light beam through the detection port 403, and the light beam can enter the second detection component 3 through the detection port 403. While ensuring the formation of the detection optical path 5, the protective cover 402 can also effectively protect the first detection component 2 and the second detection component 3, and prevent the detection components from being damaged or the emission port from being blocked after oil and other impurities splash onto the detection components. This can effectively improve the stability of the tangled rope detection of the detection component and effectively solve the problem of poor detection reliability of the existing tangled rope detection structure of the roll.

[0033] Specifically, when the detection component is working normally, a detection optical path 5 will be formed on one side of the drum 1 in the radial direction. When the wire rope 101 becomes tangled, the current wire rope 101 will be incorrectly wrapped around the outside of the already wound wire rope 101. Since the diameter of the wire rope 101 is increased at this time, it will block the detection optical path 5. When the detection optical path 5 is interrupted, the operator will be alerted that a tangled rope phenomenon has occurred.

[0034] Furthermore, there are no strict limitations on the specific installation of the testing bracket 4. It can be installed on a nearby rotating platform or machine body instead of the roll frame, as long as the first testing piece 2 and the second testing piece 3 can be installed in the designated positions.

[0035] In one possible implementation, such as Figure 3 and Figure 4 As shown, the first detection element 2 is a laser emitter, and the second detection element 3 is a laser receiver. The first detection element 2 emits a laser towards the second detection element 3 to form a detection optical path 5. The structure of the first detection element 2 and the second detection element 3 is simple and reliable, and easy to process and manufacture.

[0036] It is understood that, as an alternative implementation, the first detection element 2 can be a laser receiver and the second detection element 3 can be a laser emitter, as long as the detection optical path 5 can be formed.

[0037] In one possible implementation, the first detection element 2 has a laser emitter and a laser receiver, and the second detection element 3 is a reflector. The first detection element 2 emits a laser toward the second detection element 3 and receives the laser reflected by the second detection element 3 to form a detection optical path 5. In this form, the main working components of the first detection element 2 can be integrated into the same component, which is convenient for installation and disassembly, inspection and maintenance.

[0038] It is understood that, as an alternative implementation, the first detection element 2 can be a reflector, while the second detection element 3 has a laser emitter and a laser receiver, as long as the detection optical path 5 can be formed.

[0039] In one possible implementation, such as Figure 4 and Figure 5 As shown, the first detection element 2 is a grating emitter, and the second detection element 3 is a grating receiver. The first detection element 2 emits a laser towards the second detection element 3 to form a planar detection optical path 5. The planar detection optical path 5 has a wider detection area than the linear detection optical path 5, and can detect the tangled rope signal more stably and reliably.

[0040] It is understood that, as an alternative implementation, the first detection element 2 can be a grating receiver and the second detection element 3 can be a grating emitter, as long as the detection optical path 5 can be formed.

[0041] In one possible implementation, the first detection element 2 and the second detection element 3 are spaced apart along the axial direction of the drum 1, and the detection optical path 5 is arranged parallel to the axial direction of the drum 1. With the first detection element 2 and the second detection element 3 arranged in this way, the detection optical path 5 can detect the wire rope 101 at multiple positions with a consistent detection standard, and the detection process is stable and reliable.

[0042] In one possible implementation, the first detection element 2 and the second detection element 3 are staggered and spaced along the axial direction of the drum 1, and the detection optical path 5 is arranged in a non-plane manner with the axial direction of the drum 1. By arranging the first detection element 2 and the second detection element 3 in this way, the tangled rope state in some areas can be detected more concentratedly, and the detection distance at different positions can be changed. At the same time, the first detection element 2 and the second detection element 3 can be arranged more flexibly.

[0043] like Figure 5 and Figure 6 As shown, Figure 5 This is a schematic diagram of the frontal view. At this time, the first detection element 2 and the second detection element 3 are installed at different heights, and the plane where the detection optical path 5 is located is parallel to the axis of the roll 1.

[0044] like Figure 7 and Figure 8 As shown, Figure 5 This is a top-down view. At this time, the first detection element 2 and the second detection element 3 are located above the drum 1, and the two are arranged at the same height. The installation height of the first detection element 2 and the second detection element 3 is higher than the highest point when the wire rope 101 is normally wound.

[0045] like Figure 9 and Figure 10 As shown, Figure 6This is a top-down view. At this time, the plane where the detection optical path 5 is located is parallel to the axis of the drum 1. The first detection element 2 and the second detection element 3 are installed at different heights. The installation height of the second detection element 3 is higher than the highest point when the wire rope 101 is normally wound, while the installation height of the first detection element 2 is lower than the highest point when the wire rope 101 is normally wound.

[0046] In one possible implementation, such as Figure 1 and Figure 2 As shown, the protective cover 402 has a mounting cavity 404. The protective cover 402 is detachably connected to the detection bracket 4. The first detection element 2 and the second detection element 3 are disposed in the corresponding mounting cavity 404. This arrangement of detection elements allows the first detection element 2 and the second detection element 3 to form an integral structure with the corresponding protective cover 402. When the detection elements are disassembled, the protective cover 402 can be removed together. During installation, the protective cover 402 can also be pre-assembled with the corresponding detection elements to improve ease of use.

[0047] Specifically, there are no restrictions on the shape and size of the protective cover 402. It can be prismatic, cylindrical, etc., as long as it can form the mounting cavity 404. The specific size of the protective cover 402 can be selected according to the selected test piece, which will not be elaborated here.

[0048] In one possible implementation, the protective cover 402 is detachably connected to the detection bracket 4, and the protective cover 402 and the mounting position 401 together form a mounting cavity 404. The first detection element 2 and the second detection element 3 are disposed in the corresponding mounting cavity 404, and the first detection element 2 and the second detection element 3 are detachably connected to the corresponding mounting position 401. With this type of protective cover 402, after wear and tear from long-term operation, the protective cover 402 can be removed from the detection bracket 4 for replacement, which is more convenient for inspection and maintenance.

[0049] Specifically, there is no limitation on the detachable connection method between the protective cover 402 and the detection bracket 4, which can be a snap-fit ​​connection, bolt connection, or other connection methods; there is no limitation on the connection method between the first detection component 2 and the second detection component 3 and their corresponding mounting positions 401, which can be a snap-fit ​​connection, bolt connection, or other connection methods.

[0050] In one possible implementation, the drum device further includes a controller 6, at least one of the first detection element 2 and the second detection element 3 is connected to the controller 6, the controller 6 is used to control the rotation state of the drum 1, and after receiving the tangled rope signal transmitted by the detection element, the controller 6 can issue an alarm to the operator and at the same time control the drive unit that drives the drum 1 to stop working in order to avoid excessive wear of the wire rope.

[0051] According to an embodiment of the present invention, another aspect provides a quay crane, which includes the above-mentioned drum device, disposed at the hoisting drum, traction drum or pitching drum of the quay crane.
