Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gantry crane operation, and in particular to a stop device for a gantry crane and a gantry crane. Background Technology
[0002] Gantry cranes, also known as portal cranes, are named for their resemblance to a portal frame. Their main structure consists of a main beam, legs, a lower crossbeam, and a transport trolley. The main beam spans across the legs, forming a tall portal frame structure that carries a lifting trolley that moves laterally along the main beam rails to lift and move goods. They have a wide range of applications, primarily in ports, docks, railway freight yards, and large factories, handling the loading, unloading, and transfer of containers, heavy machinery, and other goods, greatly improving logistics efficiency. In terms of movement, gantry cranes are equipped with a traveling mechanism at the bottom, enabling longitudinal movement via wheels mounted on ground rails. Some models also have trackless travel capabilities, relying on rubber tires and steering devices to flexibly turn and move on flat ground, adapting to different work site requirements.
[0003] In practical use, when the gantry crane is working at the end of the traveling track, it may detach from the track. To prevent this, reinforced concrete is installed at both ends of the traveling track as a stop device. However, the construction period for reinforced concrete structures is long, and it increases construction costs. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, which involves setting up reinforced concrete structures at both ends of the traveling track of a gantry crane as a stop device, resulting in a long construction period and high cost, and to provide a stop device for a gantry crane and a gantry crane.
[0005] In a first aspect, the present invention provides a stop device for a gantry crane, comprising:
[0006] A stop post, which is used to be welded to the top surface of the end of the travel track;
[0007] A connecting rod, one end of which is connected to the side of the stop post, and the axis of the connecting rod is perpendicular to the axis of the stop post;
[0008] A limiting rod is connected to the top surface of the connecting rod. The axis of the limiting rod is parallel to the length direction of the traveling track. The stop end of the limiting rod protrudes from the stop column towards the traveling area of the gantry crane. The limiting rod can abut against the outrigger extension section of the gantry crane.
[0009] The height of the top surface of the stop post is determined according to the actual situation, and the distance from the limit rod to the stop post is determined according to the actual situation.
[0010] This application, by setting a stop column, a connecting rod, and a limiting rod, ensures that the end of the limiting rod facing the traveling area of the gantry crane abuts against the extended section of the gantry crane's outriggers. When the gantry crane travels to the end of the traveling track, the limiting rod abuts against the extended section of the gantry crane's outriggers to stop it, thereby minimizing the risk of the gantry crane derailing from the traveling track. Compared to existing technologies that use reinforced concrete structures for stops at the ends of the traveling track, this application only requires welding a stop column to the end of the track and installing a connecting rod on the stop column. The connecting rod connects to the limiting rod, thus achieving stop via the limiting rod. This simplifies operation and shortens the construction period; the elimination of the need for reinforced concrete structures reduces construction costs.
[0011] Preferably, the stop end of the limiting rod is a pointed tip.
[0012] The stop end is a pointed tip, which reduces the weight of the limit rod, allowing it to be fixed to the connecting rod in a cantilever manner as much as possible. This avoids the other end of the limit rod being too long, thus reducing construction costs. Furthermore, the limit rod is long enough to stop the gantry crane.
[0013] Preferably, the angle of the tip of the stop end is 40°-45°.
[0014] The angle of the stop end tip is 40°-45°, which is moderate and avoids the situation where the tip is too small, making it easy to be damaged. It also reduces the weight of the limit rod as much as possible.
[0015] Preferably, the limiting rod is disposed outside the travel track.
[0016] The limit rod is located on the outside of the travel track and is adapted to the position of the outrigger extension section of the gantry crane.
[0017] Preferably, a reinforcing plate is provided on the side of the stop column facing away from the traveling area of the gantry crane.
[0018] The stop column is equipped with a reinforcing plate to ensure the load-bearing capacity of the stop device as much as possible, which helps to improve the structural stability.
[0019] Preferably, the reinforcing plate includes a horizontal unit plate and a vertical unit plate. The plane of the horizontal unit plate is perpendicular to the axis of the traveling track, and the plane of the vertical unit plate is parallel to the axis of the traveling track. The horizontal unit plate is connected to the outer wall of the stop column, and the vertical unit plate is connected to the horizontal unit plate.
[0020] Horizontal unit panels are installed and connected to the outer wall of the retaining columns to minimize stress concentration in the retaining columns. Vertical unit panels are also installed to improve structural stability.
[0021] Preferably, the side of the stop column facing away from the traveling area of the gantry crane is also provided with a diagonal brace.
[0022] Installing diagonal braces helps improve structural stability.
[0023] Preferably, it further includes a contact sensor and an alarm device, wherein the contact sensor is disposed at the stop end of the limiting rod, and the contact sensor and the alarm device are connected.
[0024] The contact sensor is installed at the stop end and is connected to the alarm device. When the stop end comes into contact with the gantry crane, the alarm device will sound an alarm, making it easier for the operator to make adjustments.
[0025] Preferably, it further includes a buffer component, which is disposed on the outrigger extension section of the gantry crane and is used to connect to the stop end of the limiting rod.
[0026] The buffer device can be made of rubber, foam, or spring. Installing a buffer device on the outrigger extension of the gantry crane minimizes damage to the limit rods and extends the service life of the device.
[0027] In a second aspect, the present invention provides a gantry crane, comprising a main beam and a traveling track, wherein the top surface of the end of the traveling track is provided with a stop device for the gantry crane as described above.
[0028] The top surface of the end of the gantry crane's traveling track is equipped with the aforementioned stop device, which can prevent the gantry crane from leaving the traveling track as much as possible, facilitate construction, and help reduce construction costs.
[0029] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0030] 1. This utility model provides a stopping device for a gantry crane, comprising a stopping column, a connecting rod, and a limiting rod. The stopping column is welded to the top surface of the end of the traveling track. The connecting rod connects to the stopping column, and the limiting rod connects to the connecting rod. The axis of the limiting rod is parallel to the length direction of the traveling track. The limiting rod is provided with a stopping end for abutting against the outrigger extension of the gantry crane. By providing the stopping column, connecting rod, and limiting rod, this application ensures that the end of the limiting rod facing the traveling area of the gantry crane abuts against the outrigger extension of the gantry crane. Therefore, when the gantry crane travels to the end of the traveling track, the limiting rod abuts against the outrigger extension of the gantry crane to stop it, thereby minimizing the risk of the gantry crane derailing from the traveling track. Compared to existing technologies that require reinforced concrete structures to stop at the ends of the travel track, this application only requires welding stop columns to the ends of the track and installing connecting rods on the stop columns. The connecting rods are connected to limiting rods, which can then provide stopping power. This simple operation helps to shorten the construction cycle. Furthermore, the absence of reinforced concrete structures reduces construction costs, thus overcoming the shortcomings of existing technologies that require reinforced concrete structures at both ends of the gantry crane's travel track as stopping devices, resulting in long construction cycles and high costs.
[0031] 2. This utility model provides a gantry crane, which includes a main beam and a traveling track. The top surface of the end of the traveling track is provided with a stop device for the gantry crane as described above, which can prevent the gantry crane from leaving the traveling track as much as possible, facilitates construction, and helps to reduce construction costs.

[0036] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.
[0037] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.
[0038] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.
[0039] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.
[0040] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.
[0041] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.
[0042] Example 1
[0043] like Figures 1 to 2 As shown, a stopping device for a gantry crane includes:
[0044] Stop post 1, the stop post 1 is used to be welded to the top surface of the end of the travel track 6;
[0045] A connecting rod 5, one end of which is connected to the side of the stop column 1, and the axis of the connecting rod 5 is perpendicular to the axis of the stop column 1;
[0046] The limiting rod 7 is connected to the top surface of the connecting rod 5. The axis of the limiting rod 7 is parallel to the length direction of the traveling track 6. The stop end of the limiting rod 7 protrudes from the stop column 1 towards the traveling area of the gantry crane. The limiting rod 7 can abut against the outrigger extension section of the gantry crane.
[0047] The height of the top surface of the stop post 1 is determined according to the actual situation, and the distance from the limit rod 7 to the stop post 1 is determined according to the actual situation.
[0048] This application, by setting a stop column 1, a connecting rod 5, and a limiting rod 7, ensures that the end of the limiting rod 7 facing the traveling area of the gantry crane abuts against the outrigger extension of the gantry crane. When the gantry crane travels to the end of the traveling track 6, the limiting rod 7 abuts against the outrigger extension of the gantry crane to stop it, thereby minimizing the risk of the gantry crane leaving the traveling track 6. Compared to the prior art that sets a reinforced concrete structure stop at the end of the traveling track 6, this application only requires welding the stop column 1 to the end of the track and setting the connecting rod 5 on the stop column 1. The connecting rod 5 connects to the limiting rod 7, thus achieving stop via the limiting rod 7. This simple operation helps shorten the construction period; the elimination of the need for a reinforced concrete structure reduces construction costs.
[0049] In optional implementations, such as Figure 1 As shown, the stop end of the limiting rod 7 is a pointed tip. This pointed tip reduces the weight of the limiting rod 7, allowing it to be fixed to the connecting rod 5 in a cantilever configuration as much as possible. It also minimizes the need for an excessively long other end of the limiting rod 7 to balance it, thus reducing construction costs. Furthermore, the limiting rod 7 has sufficient length to stop the gantry crane. In this embodiment, the angle of the pointed tip is 40°-45°, a moderate angle that avoids the possibility of the tip being easily damaged if the angle is too small, and also minimizes the weight of the limiting rod 7.
[0050] In an optional embodiment, the limiting rod 7 is disposed outside the travel track 6.
[0051] In an optional embodiment, a reinforcing plate 4 is provided on the side of the stop column 1 facing away from the traveling area of the gantry crane to ensure the load-bearing capacity of the stop device as much as possible and to improve the structural stability.
[0052] In this embodiment, the reinforcing plate 4 includes a horizontal unit plate and a vertical unit plate. Figures 1-2 (Not shown in the image), the plane containing the horizontal unit plate is perpendicular to the axis of the walking track 6, and the plane containing the vertical unit plate is parallel to the axis of the walking track 6. The horizontal unit plate is connected to the outer wall of the stop column 1, and the vertical unit plate is connected to the horizontal unit plate. In this embodiment, the position of the vertical unit plate and the diagonal brace 2 can be connected or avoided; this application does not impose any restrictions.
[0053] like Figure 1 As shown, the side of the stop column 1 facing away from the traveling area of the gantry crane is also provided with a diagonal brace 2. The bottom end of the diagonal brace 2 is connected to the bottom connecting block 3, which is located on the ground.
[0054] In optional implementations, a contact sensor and an alarm device are also included. Figures 1-2 (Not shown in the image), the contact sensor is located at the stop end of the limit rod 7, and the contact sensor is connected to the alarm device. Since the contact sensor is located at the stop end and connected to the alarm device, the alarm device will sound an alarm when the stop end contacts the gantry crane, facilitating adjustments by the operator.
[0055] In optional implementations, a buffer component is also included. Figures 1-2 (Not shown in the diagram), the buffer component is disposed on the outrigger extension section of the gantry crane, and the buffer component is used to connect to the stop end of the limiting rod 7. In this embodiment, the buffer device can be a rubber component, a foam component, or a spring component. Providing a buffer device on the outrigger extension section of the gantry crane minimizes damage to the limiting rod 7 and helps to improve the service life of the device.
[0056] Example 2
[0057] A gantry crane includes a main beam and a traveling rail 6. The top surface of the end of the traveling rail 6 is provided with a stop device for the gantry crane as described in Embodiment 1, which can prevent the gantry crane from leaving the traveling rail as much as possible, facilitates construction, and helps reduce construction costs.
[0058] The above content is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
