Description

Technical Field

[0001] This utility model belongs to the field of fall prevention technology for high-altitude operations, and particularly relates to a connection device between a crane stop and a safety zipline. Background Technology

[0002] Overhead cranes, also known as bridge cranes, are lifting devices that span over workshops and factories for material handling. Their tracks are typically erected on two adjacent upright columns within the workshop. In existing technology, to ensure safe production and prevent major accidents caused by the overhead crane derailing due to equipment malfunction or operational errors, special stop devices are usually installed at the ends of the overhead crane tracks (i.e., at the column locations). These stop devices effectively slow down or prevent abnormal movement of the overhead crane by absorbing its kinetic energy, thus providing reliable safety protection.

[0003] In existing factories equipped with overhead cranes, safety ziplines are typically installed near the cranes to ensure the safety of workers performing tasks at height. These safety ziplines are generally fixed to columns, providing reliable fall protection for maintenance personnel moving at heights and significantly improving operational safety. However, in practice, it has been found that some factory buildings have walls or other obstacles between adjacent columns. These obstacles hinder the proper installation of safety ziplines, resulting in a lack of necessary fixed supports and thus affecting the overall safety protection effect.

[0004] Therefore, there is an urgent need for a connection device between the crane stop and the safety cable to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a connection device between the crane stop and the safety cable, which can connect the safety cable to the crane stop, effectively solving the problem that the safety cable has no fixed support point when there are obstacles between adjacent columns. It can also adjust the distance from the end of the steel cable to the crane stop to ensure that the steel cable can be kept taut, thus ensuring the safety of workers working at height.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A connection device for a crane stop and a safety cable is provided. The crane stop is located on one side of the column along the width of the crane track. The connection device for the crane stop and the safety cable includes:

One end of the second adjustment member can be connected to the steel cable of the safety zipline, and the other end is movably connected to the second end of the fixed adjustment member along its extension direction.

[0010] The support component has one end detachably connected to the side of the support away from the adjustment component, and the other end detachably connected to the crane stop.

[0011] Optionally, both the first adjusting member and the second adjusting member are provided with a first external thread. The first external thread of the first adjusting member and the first external thread of the second adjusting member have opposite directions of rotation. The fixed adjusting member includes an adjusting tube, and the adjusting tube is provided with a first internal thread. Both the first adjusting member and the second adjusting member are threadedly connected to the adjusting tube through the first external thread and the first internal thread.

[0012] Optionally, the regulating tube is provided with a first driving hole, which is configured to insert a first driving rod, and the regulating tube can be driven to rotate by applying force through the first driving rod.

[0013] Optionally, the first adjusting member is provided with a first limiting member, which is located between the support and the adjusting tube, and is used to limit the maximum distance that the first adjusting member can move along its extension direction; the second adjusting member is provided with a second limiting member, which is located between the steel cable and the adjusting tube, and is used to limit the maximum distance that the second adjusting member can move along its extension direction.

[0014] Optionally, the support assembly includes a first support member, a second support member, and a fixed support member. One end of the first support member is detachably connected to the support, and the other end is movably connected to the third end of the fixed support member along its extension direction. One end of the second support member is detachably connected to the crane stop, and the other end is movably connected to the fourth end of the fixed support member along its extension direction.

[0015] Optionally, both the first support member and the second support member are provided with a second external thread. The second external thread of the first support member and the second external thread of the second support member have opposite directions of rotation. The fixed support member includes a support tube, and a second internal thread is provided inside the support tube. Both the first support member and the second support member are threadedly connected to the support tube through the second external thread and the second internal thread.

[0016] Optionally, the support tube is provided with a second drive hole, which is configured to insert a second drive rod, and the support tube can be driven to rotate by applying force through the second drive rod.

[0017] Optionally, the end of the second adjusting member away from the fixed adjusting member is provided with an installation groove, and the steel cable can be inserted into the installation groove and make close contact with the groove wall.

[0018] Optionally, the support includes a first support plate and a second support plate that are perpendicular to each other. One end of the first support plate is detachably connected to the crane stop, and the other end is detachably connected to the first adjusting member. The first support plate is perpendicular to the steel cable. The second support plate is located on the side of the first support plate away from the first adjusting member and is detachably connected to the support assembly.

[0019] Optionally, the connection device between the crane stop and the safety cable also includes a third bolt and a sixth nut. The end of the support assembly is provided with a connecting groove. The end of the second support plate away from the first support plate is inserted into the connecting groove. The third bolt passes through the connecting groove and the second support plate located in the connecting groove and is threadedly connected to the sixth nut.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model provides a connection device between a crane stop and a safety zipline. The steel cable of the safety zipline is connected to a second adjusting member. The second adjusting member and a first adjusting member are respectively connected to both ends of a fixed adjusting member. The first adjusting member is connected to a support, which is installed on the crane stop, thus realizing the connection between the safety zipline and the crane stop. Because the crane stop is located on one side of the column along the width of the crane track, it will not slam against obstacles between the columns. Therefore, connecting the safety zipline to the crane stop effectively solves the problem of the safety zipline having no fixed support point when there are obstacles between adjacent columns, ensuring the life, health and safety of workers when maintaining the crane. In addition, both the first and second adjusting members are movably connected to the fixed adjusting member along their extension direction. That is, the length of the adjusting components between the support and the end of the steel cable can be adjusted, so that the distance from the end of the steel cable to the crane stop can be adjusted, that is, the tension of the steel cable between two adjacent columns can be adjusted, ensuring that the steel cable is kept taut, reducing the swaying amplitude of the steel cable during use, enhancing the overall stability of the safety zipline, and ensuring the safety of workers working at height. The support component and the adjustment component are located on both sides of the support. Because the adjustment component is connected to the steel cable, the side of the support connected to the adjustment component will be subjected to a large tensile force, which can easily cause the support to deform. The support component can connect the side of the support away from the adjustment component to the crane stop. The force between the support and the support component is opposite to the tensile force mentioned above, thereby balancing the forces on both sides of the support and ensuring the structural stability of the support.

[0032] It should be understood that in the description of this utility model, the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 4As shown, this embodiment provides a connection device between a crane stop and a safety zipline, which can connect the safety zipline to the crane stop 100. This effectively solves the problem that the safety zipline has no fixed support point when there are obstacles between adjacent columns. It can also adjust the distance from the end of the steel cable 200 to the crane stop 100 to ensure that the steel cable 200 is in a taut state, thus ensuring the safety of workers working at height.

[0036] See Figure 1 The crane stop 100 is located on one side of the column along the width of the crane track. The connection device between the crane stop and the safety zipline includes a support 1, an adjusting component 2, and a supporting component 3. The support 1 can be detachably installed on the crane stop 100. The adjusting component 2 includes a first adjusting member 21, a second adjusting member 22, and a fixed adjusting member 23. One end of the first adjusting member 21 is detachably connected to the support 1, and the other end is movably connected to the first end of the fixed adjusting member 23 along its extension direction. One end of the second adjusting member 22 can be connected to the steel cable 200 of the safety zipline, and the other end is movably connected to the second end of the fixed adjusting member 23 along its extension direction. One end of the supporting component 3 is detachably connected to the side of the support 1 opposite to the adjusting component 2, and the other end is detachably connected to the crane stop 100. Here, the first end and the second end refer to the two ends of the fixed adjusting member 23.

[0037] The overhead crane stop and safety cable connection device provided in this embodiment connects the steel cable 200 of the safety cable to the second adjusting member 22. The second adjusting member 22 and the first adjusting member 21 are respectively connected to both ends of the fixed adjusting member 23. The first adjusting member 21 is connected to the support 1, and the support 1 is installed on the overhead crane stop 100, thereby realizing the connection between the safety cable and the overhead crane stop 100. Because the overhead crane stop 100 is located on one side of the column along the width of the overhead crane track, it will not collide with obstacles between the columns. Therefore, connecting the safety cable to the overhead crane stop 100 can effectively solve the problem of the safety cable having no fixed support point when there are obstacles between adjacent columns, ensuring the life, health and safety of the staff when maintaining the overhead crane. Furthermore, both the first adjusting component 21 and the second adjusting component 22 are movably connected to the fixed adjusting component 23 along their extension direction. This means the length of the adjusting component 2 between the support 1 and the end of the steel cable 200 can be adjusted, allowing adjustment of the distance from the end of the steel cable 200 to the crane stop 100. This also allows adjustment of the tension of the steel cable 200 between two adjacent columns, ensuring the steel cable 200 remains taut, reducing the swaying amplitude during use, enhancing the overall stability of the safety zipline, and guaranteeing the safety of workers operating at heights. The support component 3 and the adjusting component 2 are located on opposite sides of the support 1. Because the adjusting component 2 is connected to the steel cable 200, the side of the support 1 connected to the adjusting component 2 experiences a large tensile force, which can easily cause deformation of the support 1. The support component 3 connects the side of the support 1 away from the adjusting component 2 to the crane stop 100. The force between the support 1 and the support component 3 is opposite to the aforementioned tensile force, thus balancing the forces on both sides of the support 1 and ensuring the structural stability of the support 1.

[0038] In an optional embodiment, the adjusting component 2 is a turnbuckle, the first adjusting member 21 and the second adjusting member 22 are the screws of the turnbuckle, and the fixing adjusting member 23 is the nut of the turnbuckle.

[0039] In another optional embodiment, both the first adjusting member 21 and the second adjusting member 22 are provided with a first external thread. The first external thread of the first adjusting member 21 and the first external thread of the second adjusting member 22 have opposite directions of rotation. The fixed adjusting member 23 includes an adjusting tube with a first internal thread inside. Both the first adjusting member 21 and the second adjusting member 22 are threadedly connected to the adjusting tube through the first external thread and the first internal thread. The threaded connection is simple to operate and allows the first adjusting member 21 and the second adjusting member 22 to move stably within the adjusting tube. The opposite directions of the first external threads of the first adjusting member 21 and the second adjusting member 22 ensure that tightening the first adjusting member 21 to the adjusting tube will not cause the already tightened second adjusting member 22 to be loosened, or tightening the second adjusting member 22 to the adjusting tube will not cause the already tightened first adjusting member 21 to be loosened. This allows for independent adjustment of the connection length between the first adjusting member 21 and the adjusting tube, as well as the connection length between the second adjusting member 22 and the adjusting tube, making the adjustment range of the length of the adjusting assembly 2 more flexible and convenient.

[0040] For example, both the first adjusting member 21 and the second adjusting member 22 are rods, and the adjusting tube is a hollow round steel tube, which can provide space for the movement of the first adjusting member 21 and the second adjusting member 22.

[0041] In this embodiment, two first nuts are provided inside the adjusting tube. The first internal thread is the thread of the first nut. The first adjusting member 21 and the second adjusting member 22 are both screws and are threadedly connected to the first nuts. Preferably, the adjusting tube is welded to the first nuts to limit the displacement of the first nuts inside the adjusting tube. In other embodiments, the first internal thread can also be directly machined on the inner wall of the adjusting tube. The first internal thread is provided along the extension direction of the adjusting tube, and preferably along the entire length of the adjusting tube, thereby increasing the moving length of the first adjusting member 21 and the second adjusting member 22 and expanding the adjustment range of the length of the adjusting assembly 2.

[0042] In this embodiment, the adjusting tube is provided with a first driving hole, which is configured to insert a first driving rod. Force applied by the first driving rod can drive the adjusting tube to rotate, facilitating the adjustment of the length of the adjusting assembly 2. The first driving rod is preferably an Allen wrench or a reinforcing bar. When adjusting the length of the adjusting assembly 2, i.e., the tension of the steel cable 200, one end of the Allen wrench or reinforcing bar is inserted into the first driving hole, and rotation around the center line of the adjusting assembly 2 adjusts the distance between the first adjusting member 21 and the second adjusting member 22, thereby adjusting the tension of the steel cable 200.

[0043] In this embodiment, see Figure 1The first adjusting member 21 is provided with a first limiting member 211, which is located between the support 1 and the adjusting tube. The first limiting member 211 is used to limit the maximum distance that the first adjusting member 21 can move along its extension direction, so as to prevent the end of the adjusting tube from colliding with the support 1 and causing damage to the adjusting tube or the support 1. The second adjusting member 22 is provided with a second limiting member 221, which is located between the steel cable 200 and the adjusting tube. The second limiting member 221 is used to limit the maximum distance that the second adjusting member 22 can move along its extension direction, so as to prevent the end of the steel cable 200 from moving into the inner cavity of the adjusting tube and affecting the subsequent maintenance and replacement of the steel cable 200.

[0044] For example, see Figure 1 Both the first limiting member 211 and the second limiting member 221 are nuts.

[0045] In another optional embodiment, the length of the adjusting assembly 2 can also be adjusted by sliding the first adjusting member 21 and the second adjusting member 22 to the adjusting tube. Exemplarily, the fixing adjusting member 23 further includes a first bolt and a second nut, and the first adjusting member 21 and the second adjusting member 22 slide within the adjusting tube. The first adjusting member 21 has a first connecting hole at one end within the adjusting tube, and the second adjusting member 22 has a second connecting hole at one end within the adjusting tube. A plurality of first fixing holes and a plurality of second fixing holes are spaced apart along the extending direction of the adjusting tube, and the first fixing holes and the second fixing holes are symmetrically arranged along the axis of the extending direction of the adjusting tube. When the first adjusting member 21 slides to the designated position within the adjusting tube, the screw of the first bolt passes through the first fixing hole, the first connecting hole, and the second fixing hole in sequence. The head of the first bolt abuts against the outer wall of the adjusting tube around the first fixing hole, and the second nut abuts against the outer wall of the adjusting tube around the second fixing hole, and is tightened with the first bolt to fix the sliding position of the first adjusting member 21 within the adjusting tube. Similarly, when the second adjusting member 22 slides to the designated position within the adjusting tube, the screw of the first bolt passes through the first fixing hole, the second connecting hole, and the second fixing hole in sequence. The head of the first bolt abuts against the outer wall of the adjusting tube around the first fixing hole, and the second nut abuts against the outer wall of the adjusting tube around the second fixing hole, and is tightened with the first bolt to fix the sliding position of the second adjusting member 22 within the adjusting tube. This adjusts the length of the adjusting assembly 2. The designated position where the first adjusting member 21 and the second adjusting member 22 slide within the adjusting tube refers to the position where the steel cable 200 can remain taut. This configuration allows for simultaneous adjustment of the connection lengths between the first adjusting member 21 and the second adjusting member 22 and the adjusting tube, as well as individual adjustment of the connection lengths between the first adjusting member 21 and the adjusting tube and the second adjusting member 22 and the adjusting tube. This makes the adjustment range of the steel cable tension 200 more flexible and convenient.

[0046] In an optional embodiment, the support component 3 is a turnbuckle.

[0047] In another alternative embodiment, see [link to relevant documentation] Figure 1 The support assembly 3 includes a first support member 31, a second support member 32, and a fixed support member 33. One end of the first support member 31 is detachably connected to the support 1, and the other end is movably connected to the third end of the fixed support member 33 along its extension direction. One end of the second support member 32 is detachably connected to the crane stop 100, and the other end is movably connected to the fourth end of the fixed support member 33 along its extension direction. This arrangement allows the length of the support assembly 3 to be adjusted. By adjusting the length of the support assembly 3, the magnitude of the supporting force on the side of the support 1 away from the adjusting assembly 2 can be adjusted, thereby making the force on both sides of the support 1 more balanced and ensuring the stability of the support 1 structure. The third and fourth ends refer to the two ends of the fixed support member 33.

[0048] In this embodiment, both the first support member 31 and the second support member 32 are provided with a second external thread. The second external thread of the first support member 31 and the second external thread of the second support member 32 have opposite directions of rotation. The fixed support member 33 includes a support tube, and the support tube is provided with a second internal thread. Both the first support member 31 and the second support member 32 are threadedly connected to the support tube through the second external thread and the second internal thread. The threaded connection is simple to operate and allows the first support member 31 and the second support member 32 to move stably within the support tube. The first external threads of the first support member 31 and the second support member 32 have opposite directions of rotation, so that when the first support member 31 is tightened to the support tube, the already tightened second support member 32 and the support tube will not be loosened, or when the second support member 32 is tightened to the support tube, the already tightened first support member 31 and the support tube will not be loosened. This allows for individual adjustment of the connection length between the first support member 31 and the support tube, as well as the connection length between the second support member 32 and the support tube, making the adjustment range of the support assembly 3 length more flexible and convenient.

[0049] For example, both the first support member 31 and the second support member 32 are rods, and the support tube is a hollow round steel tube, which can provide space for the movement of the first support member 31 and the second support member 32.

[0050] In this embodiment, two third nuts are provided inside the support tube, and the second internal thread is the thread of the third nut. The first support member 31 and the second support member 32 are both screws and are threadedly connected to the third nuts. Preferably, the support tube is welded to the third nuts to restrict the displacement of the third nuts within the support tube. In other embodiments, the second internal thread can also be directly machined on the inner wall of the support tube. The second internal thread is provided along the extension direction of the support tube, and preferably along the entire length of the support tube, thereby increasing the moving length of the first support member 31 and the second support member 32 and expanding the adjustment range of the length of the support assembly 3.

[0051] In this embodiment, a second driving hole is provided on the support tube, which is configured to insert a second driving rod. Force applied by the second driving rod can drive the support tube to rotate, facilitating the adjustment of the length of the adjustment assembly 2. The second driving rod is preferably an Allen wrench or a reinforcing bar. When adjusting the length of the support assembly 3, one end of the Allen wrench or the reinforcing bar is inserted into the second driving hole, and rotation around the center line of the support assembly 3 adjusts the distance between the first support member 31 and the second support member 32, thereby adjusting the supporting force of the support 1.

[0052] In another optional embodiment, the length of the support assembly 3 can be adjusted by sliding the first support member 31 and the second support member 32 to the support tube. Exemplarily, the fixing support member 33 further includes a second bolt and a fourth nut, and the first support member 31 and the second support member 32 slide within the support tube. The first support member 31 has a third connecting hole at one end within the support tube, and the second support member 32 has a fourth connecting hole at one end within the support tube. A plurality of third fixing holes and a plurality of fourth fixing holes are spaced apart along the extension direction of the support tube, and the third fixing holes and fourth fixing holes are symmetrically arranged along the axis of the extension direction of the support tube. When the first support member 31 slides to the designated position within the support tube, the screw of the second bolt passes through the third fixing hole, the third connecting hole, and the fourth fixing hole in sequence. The head of the second bolt abuts against the outer wall of the support tube around the third fixing hole, and the fourth nut abuts against the outer wall of the support tube around the fourth fixing hole, and is tightened with the second bolt to fix the sliding position of the first support member 31 within the support tube. Similarly, when the second support member 32 slides to the designated position within the support tube, the screw of the second bolt passes through the third fixing hole, the fourth connecting hole, and the fourth fixing hole in sequence. The head of the second bolt abuts against the outer wall of the support tube around the third fixing hole, and the fourth nut abuts against the outer wall of the support tube around the fourth fixing hole, and is tightened with the second bolt to fix the sliding position of the second support member 32 within the support tube. This adjusts the length of the support assembly 3. The designated sliding position of the first support member 31 and the second support member 32 within the support tube refers to the position where the steel cable 200 can remain taut. This configuration allows for simultaneous adjustment of the connection lengths between the first support member 31 and the second support member 32 and the support pipe, as well as individual adjustment of the connection lengths between the first support member 31 and the support pipe and the second support member 32 and the support pipe, making the adjustment range of the steel cable tension 200 more flexible and convenient.

[0053] Optionally, see Figure 2 The second adjusting member 22 has an installation groove 222 at the end away from the fixed adjusting member 23. The steel cable 200 can be inserted into the installation groove 222 and make close contact with the groove wall of the installation groove 222 to connect the steel cable 200 to the second adjusting member 22.

[0054] Specifically, when connecting the steel cable 200 and the second adjusting member 22, the steel cable 200 is first inserted into the mounting groove 222, and then the second adjusting member 22 is clamped using tools such as hydraulic clamps. The groove wall of the mounting groove 222 deforms, so that the groove wall can be in close contact with the steel cable 200.

[0055] Optionally, see Figure 1 The support 1 includes a first support plate 11 and a second support plate 12 that are perpendicular to each other. One end of the first support plate 11 is detachably connected to the crane stop 100, and the other end is detachably connected to the first adjusting member 21. The first support plate 11 is perpendicular to the steel cable 200. The second support plate 12 is located on the side of the first support plate 11 away from the first adjusting member 21 and is detachably connected to the support assembly 3. The first support plate 11 provides space for the connection between the first adjusting member 21 and the support 1, and the second support plate 12 provides space for the connection between the support assembly 3 and the support 1. Moreover, both the first support plate 11 and the second support plate 12 are plate bodies, which allows workers to use materials available in the factory when manufacturing the support 1, improving the convenience of connecting the crane stop 100 and the safety cable.

[0056] Specifically, see Figure 1 The first adjusting member 21 is connected to the first support plate 11 at one end with a screw part. The connection device between the crane stop and the safety cable also includes a fifth nut 41. The fifth nut 41 is located on the side of the first support plate 11 away from the first adjusting member 21. The screw part passes through the first support plate 11 and is threadedly connected to the fifth nut 41, thereby realizing the detachable connection between the first adjusting member 21 and the first support plate 11.

[0057] In this embodiment, see Figure 1 and Figure 4 The connection device between the overhead crane stop and the safety cable also includes a third bolt 42 and a sixth nut 43. The end of the support assembly 3 is provided with a connecting groove 341. The end of the second support plate 12 furthest from the first support plate 11 is inserted into the connecting groove 341. The third bolt 42 passes through the connecting groove 341 and the second support plate 12 located within the connecting groove 341 and is threadedly connected to the sixth nut 43, thus achieving a detachable connection between the second support plate 12 and the support assembly 3. After the second support plate 12 is connected to the support assembly 3, the end of the second support plate 12 connected to the support assembly 3 can be confined within the connecting groove 341, ensuring that both sides of the second support plate 12 along its thickness direction are connected to the support assembly 3. This guarantees the uniformity of force on both sides of the second support plate 12 and effectively prevents damage to the second support plate 12 due to excessive local stress.

[0058] Specifically, see Figure 3 and Figure 4The first support member 31 has a U-shaped connecting plate 34 at the end away from the support pipe, and the connecting groove 341 is the U-shaped groove formed by the U-shaped connecting plate 34. The second support member 32 also has a U-shaped connecting plate 34 at the end away from the support pipe.
