Description

Technical Field

[0001] The invention relates to a multifunctional anchor pin placement rack, and in particular to a multifunctional anchor pin placement rack and a method for a rail-mounted crane. Background Art

[0002] Rail-mounted cranes typically install windproof anchor rods on the outside (inside or on both sides) of the gantry's balance beam for wind protection. When the crane is stopped, the anchor rods secure the crane to the anchor point. When the crane is operational, the pins connecting the anchor rods to the anchor point are removed. Anchor limit switches are installed at the anchor points to detect the removal of the pins and provide interlocking protection. The traveling mechanism can only be activated when the limit switches detect that all anchor rods are completely free of the anchor point. Because the connecting pins at the anchor points are frequently removed and installed, and there is no suitable temporary storage location after removal, the pins are sometimes placed on the traveling trolley or the ground, where they can roll and be lost. Furthermore, the anchor detection limit switches are easily damaged during the frequent installation and removal of the pins, rendering them ineffective as interlocking protection. Furthermore, once the connecting pins are removed, the anchor rods remain free. During acceleration and deceleration of the crane, the anchor rods can swing significantly and collide with the traveling trolley, wheels, and surrounding components, potentially damaging the components or the anchor rods. Summary of the Invention

[0003] In order to solve the problems of the anchor pin shaft of the above-mentioned rail-mounted crane during the disassembly, assembly and use, the present invention provides a multifunctional placement rack device for the anchor pin shaft of the rail-mounted crane, which not only solves the problem of nowhere to temporarily store the anchor pin shaft after it is removed, but also ensures that the limit detection device is not damaged, and at the same time makes the anchor rod suspended and fixed without shaking significantly. The invention has multiple functions, a simple structure, easy installation, simple and easy operation, and safety and reliability.

[0004] The technical solution adopted in the present invention is as follows:

[0005] In the first aspect, a multifunctional anchor pin placement frame device for a rail-mounted crane includes an anchor pin placement frame, a chain hanging device, and an anchor pin; the anchor pin placement frame includes an installation plate, an extension frame, a lifting ring, a detection sensor, and a pin placement plate ring; the installation plate is fixed to the end face of a traveling trolley closest to the anchor rod; the extension frame is horizontally installed on the installation plate, and a lifting ring, a detection sensor, and a pin placement plate ring are installed on the extension frame; the lifting ring is used to suspend the chain hanging device; the pin placement plate ring is used to vertically place the pin, and a detection sensor is fixed under each pin placement plate ring, and the detection sensor is used to detect whether the anchor pin is completely removed.

[0006] In a second aspect, based on the above-mentioned multifunctional anchor pin placement rack for rail-mounted cranes, the present invention further proposes a method of use, which is as follows:

[0007] When the rail-mounted crane needs to release the anchor device for walking operation, the anchor pin is first removed from the anchor fixing point of the anchor rod, and the removed anchor pin is placed in the corresponding pin placement plate ring. At this time, the detection sensor installed on the extension frame and located below the pin placement plate ring is activated to detect whether the anchor pin has been removed and placed in the pin placement plate ring. If it is detected that the anchor pin has been placed in the pin placement plate ring, it is determined that the anchor rod corresponding to the anchor pin is completely unanchored, and then the end of the anchor rod is tilted and lifted, and the hanging point of the anchor rod is pulled and fixed to the lifting ring through the hanging chain device to prevent it from shaking, and then the anchor pins of other anchor rods are continued to be removed, and the above actions are performed; when all detection sensors detect that the anchor pins are in place, the trolley running mechanism can be started.

[0008] The beneficial effects of the present invention are as follows:

[0009] 1) The present invention has a simple structure and multiple functions. It not only solves the problem of having nowhere to place the pin shaft, but also ensures that the limit detection device is not damaged, and at the same time fixes the anchor rod without shaking significantly; it makes the component design of the crane more humane and more scientific.

[0010] 2) The present invention is safe and reliable as a whole. The detection sensor is located on the anchor pin placement frame and is not easily damaged, which greatly ensures the reliability of the detection device.

[0020] As introduced in the background technology, in order to solve the deficiencies in the prior art, the present invention proposes a multifunctional placement rack and method for anchor pins for rail-mounted cranes.

[0021] In a typical embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 As shown in the figure, the specific implementation of the present invention will be described in detail below with reference to the accompanying drawings. Figure 1 and instructions attached Figure 2 ; This embodiment discloses a multifunctional anchor pin placement rack device for a rail-mounted crane, comprising an anchor pin placement rack 1, a hanging chain device 2 and an anchor pin 3; the anchor pin placement rack 1 is used to place the anchor pin 3, and at the same time it is connected to the hanging chain device 2 to realize the connection between the anchor pin placement rack 1 and the anchor pull rod 11.

[0022] Among them, the anchor pin placement frame 1 in this embodiment includes a mounting plate 4, an extension frame 5, a lifting ring 6, a detection sensor 7 and a pin placement plate ring 8; wherein the mounting plate 4 is mounted with bolts on the end face of a trolley closest to the anchor rod (generally a rail-mounted crane will include multiple trolleys, and the mounting plate 4 is fixed on the end face of a trolley closest to the anchor rod). Figure 1 As shown, the mounting plate 4 in this embodiment is fixed on Figure 1On the left end face of the walking trolley, the extension frame 5 is connected to the mounting plate 4 through a connecting piece or is integrally formed with the mounting plate 4 or is welded to the mounting plate 4, and a lifting ring 6, a detection sensor 7 and a pin placement plate ring 8 are installed on the extension frame 5; in this embodiment, two lifting rings 6 are provided, and the two lifting rings 6 are installed at both ends of the extension frame 5, and the pin placement plate ring 8 is installed in the part between the two ends of the extension frame 5, and a detection sensor 7 is fixed under each pin placement plate ring 8; further, the above-mentioned lifting ring 6 is used to hang the chain device 2, one end of the chain device 2 is connected to the mounting plate 4, and the other end is connected to the anchoring rod 11; the detection sensor 7 is used to detect whether the anchor pin 3 is completely removed and whether the anchor pin 3 is placed in the pin placement plate ring 8. Only when all the anchor pins of the entire rail crane are removed and placed in the corresponding pin placement plate ring 8, the rail crane can start walking; the function of the pin placement plate ring 8 is mainly to place the anchor pin 3 removed from the anchor point.

[0023] Further, such as Figure 2 As shown, the mounting plate 4 in this embodiment is a rectangular frame structure, the left side of which is fixed to the end face of the traveling trolley by bolts, and the right side of which is connected to the extension frame 5.

[0024] Further, such as Figure 2 As shown, the extension frame 5 in this embodiment is a steel structure, which includes a horizontal plate set horizontally and a vertical plate set vertically. The horizontal plate is vertically fixed on the top of the vertical plate, and the lifting ring 6, the detection sensor 7 and the pin placement plate ring 8 are all specified on the vertical plate; the extension frame 5 in the present invention can be an integral molding or a structure that is combined and connected together, and an integral molding is preferably used.

[0025] It should be further explained that the number of the lifting ring 6, detection sensor 7, and pin placement plate ring 8 in this embodiment is set to one or two according to whether the anchoring rod is set on only one side or both sides; that is, when the anchoring rod 11 is set on only one side, the extension frame 5 is only provided with one lifting ring 6, one detection sensor 7, and one pin placement plate ring 8; when the anchoring rod is set on both sides, the extension frame 5 can be provided with two lifting rings 6, two detection sensors 7, and two pin placement plate rings 8. Figure 1 In the embodiment, since the anchoring rod 11 is provided on both sides, two lifting rings 6, two detection sensors 7, and two pin placement plate rings 8 are provided on the extension frame 5.

[0026] Further preferably, the detection sensor 7 is in the form of a cylindrical proximity switch. The detection sensor 7 in this embodiment is a stud-type proximity switch. Therefore, the extended length of the detection sensor 7 can be adjusted on the extension frame 6 according to the setting position of the pin placement plate ring 8 and the placement of the anchor pin 3, etc., to ensure that when the anchor pin 3 is placed on the pin placement plate ring 8, the detection sensor 7 can detect whether the anchor pin 3 is placed.

[0027] Preferably, a signal wire fixing card for the detection sensor 7 is also provided on the extension frame 6. All the detection sensors 7 on the rail-mounted crane are connected to the control system of the rail-mounted crane through their respective signal wires. Only when all the detection sensors 7 detect that the anchor pin shaft 3 has been placed in place can the rail-mounted crane start moving.

[0028] Furthermore, the chain device 2 in this embodiment is one or two sets, and the number depends on the number of anchor rods. One end of the chain device 2 is connected to the lifting ring 6, and the other end is connected to the hanging point of the anchor rod 11 to prevent the anchor rod 11 from swinging back and forth and hitting the end face of the walking trolley after the anchor pin 3 of the anchor rod 11 is removed.

[0029] Preferably, both ends of the chain device are provided with anti-drop hooks for easy hooking, and the length of the hooks is such that after the two ends of the chain device are connected, the bottom of the anchor rod does not contact the anchor point and the ground after the anchor rod is lifted.

[0030] Figure 3 This is a schematic diagram of the anchor pin shaft of the present invention. The anchor pin shaft 3 is one or two sets, and the number depends on the number of anchor rods. In this embodiment, the anchor pin shaft 3 includes two, and each anchor pin shaft 3 includes a pin shaft 9 and a handle 10. The handle 10 is welded to the end of the pin shaft shoulder for conveniently lifting the pin shaft 9. The pin shaft 9 is used to be inserted into the pin shaft placement plate ring 8 after disassembly and assembly.

[0031] Further preferably, the above-mentioned lifting ring 6 is in the form of a lifting ring bolt and is provided at the end of the extension frame 5 .

[0032] The method of using the above device is as follows:

[0033] Generally, when a rail-mounted crane is not moving, the anchor rod 11 on it is fixed to the ground or the anchor point of the guide rail through the anchor pin 3. When the rail-mounted crane needs to release the anchor device for walking operation, the anchor pin 3 needs to be removed from the anchor fixing point of the anchor rod 11, and the removed anchor pin 3 is placed in the corresponding pin placement plate ring 8. At this time, the detection sensor 7 installed on the extension frame 5 and located below the pin placement plate ring 8 is activated. The detection sensor 7 detects whether the anchor pin 3 has been removed and placed in the pin placement plate ring 8. If it is detected that the anchor pin 3 has been placed in the pin placement plate ring, it can be determined that the anchor rod 11 corresponding to the anchor pin 3 is completely unanchored, and then the detection signal is sent to the control system of the rail-mounted crane, and then the end of the anchor rod is tilted and lifted, and the chain device is used to hang the anchor rod. 2 The anchor rod suspension point is pulled and fixed on the lifting ring 6 to prevent it from shaking, and then the anchor pins 3 of other anchor rods are removed and placed in another pin placement plate ring 8. The detection sensor 7 below the pin placement plate ring 8 is activated to detect whether the anchor pin 3 has been removed and placed in the pin placement plate ring 8. If it is detected that the anchor pin 3 has been placed in the pin placement plate ring, it can be determined that the anchor rod 11 corresponding to the anchor pin 3 has been completely unanchored, and then the detection signal is sent to the control system of the rail-mounted crane. Then, the end of the anchor rod is tilted and lifted, and the anchor rod suspension point is pulled and fixed on the lifting ring 6 by the hanging chain device 2 to prevent it from shaking. When the control system of the rail-mounted crane determines that it has received signals from all detection sensors 7, the rail-mounted crane starts to move.

[0034] The above-mentioned anchoring device and the trolley running mechanism are provided with an interlocking protection function, and all detection sensors 7 are controlled in series in the control system. Only when all the anchors of the rail-mounted crane are released, that is, all the detection sensors 7 at this position are activated, can the trolley running mechanism be started.

[0035] Finally, it should be noted that relational terms such as first and second are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.

[0036] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
