Description

Technical Field

[0001] The present disclosure relates to the technical field of safety protection, and particularly to a seat belt suspension device. Background Art

[0002] Currently, most coal transport vehicles used for coal transportation are equipped with electric tarpaulins, which can be automatically opened. However, due to the constraints of the use environment, some vehicles still require manual opening of the tarpaulins. The opening process is a high-altitude operation. To ensure the safety of the staff, when the staff opens the coal transport vehicle's tarpaulin, they need to wear a seat belt and hang the seat belt on the steel wire rope on the vertical pole.

[0003] In the related art, the vertical poles are mostly made of round tubes or square steels, arranged in the form of a gantry, and steel wire ropes are provided for hanging the seat belt. During use, the vertical poles may be collided by the coal transport vehicle, resulting in movement or even tipping, and the personal safety of the staff cannot be guaranteed. Summary of the Utility Model

[0004] The purpose of the present disclosure is to provide a seat belt suspension device with strong anti-movement and anti-tipping capabilities to at least partially solve the above technical problems.

[0005] To achieve the above purpose, the present disclosure provides a seat belt suspension device, including:

[0006] Gantry frames, the number of the gantry frames is set to at least two;

[0007] Embedded parts, connected to the gantry frames and buried underground; and

[0008] Steel wire ropes, connected to two adjacent gantry frames for hanging the seat belt.

[0009] Optionally, the gantry frame includes a cross bar and a vertical pole connected to each other. The embedded part includes an embedded block buried underground and a bracket cast-connected to the embedded block, and the bracket is used to support the vertical pole.

[0010] Optionally, the vertical pole is configured as an octagonal pole.

[0011] Optionally, the bracket includes a threaded rod and a support plate connected to the threaded rod. The threaded rod is cast-connected to the embedded block, and the vertical pole is connected to the support plate through a connecting piece.

[0012] Optionally, the threaded rod penetrates through the support plate and is flange-connected to the connecting piece, and the vertical pole is flange-connected to the connecting piece.

[0013] Optionally, reinforcing ribs are provided at the flange connection ends of the support plate and the connecting piece and at the flange connection ends of the vertical pole and the connecting piece.

[0014] Optionally, the vertical pole includes a plurality of vertical pole segments that are sequentially flange-connected through flange portions.

[0015] Optionally, one of the vertical pole and the horizontal pole has a connecting portion, and the connecting portion is flange-connected to the other of the vertical pole and the horizontal pole and is provided with a reinforcing rib.

[0016] Optionally, the steel wire rope is connected to two adjacent horizontal poles, and a limiting ring for the steel wire rope to pass through is arranged on the horizontal pole to limit the movement of the steel wire rope along the axial direction of the horizontal pole.

[0017] Optionally, the free end of the steel wire rope circumferentially surrounds the horizontal pole and passes through the limiting ring at least once, and the free end of the steel wire rope is fixedly connected to the middle section of the steel wire rope through a rope buckle.

[0018] By the above technical solution, when the safety belt suspension device is applied to the opening of the tarpaulin on the top of the coal transport vehicle for coal transportation, the staff can wear the safety belt and hang the safety belt on the steel wire rope connected between two adjacent gantries. Compared with the related art in which the gantry is erected on the ground through a cement pier or fixed to the ground through expansion bolts, the gantry in the present disclosure is connected with embedded parts buried underground for fixation, improving the anti-movement and anti-tipping capabilities of the gantry, and thus ensuring the personal safety of the staff.

[0027] The following detailed description is made with reference to the accompanying drawings for the specific implementation manners of the present disclosure. It should be understood that the specific implementation manners described herein are only for the purpose of illustration and explanation of the present disclosure, and are not used to limit the present disclosure.

[0028] In the present disclosure, unless otherwise stated, "inside and outside" refer to the inside and outside of the contour of the corresponding component; "far and near" refer to the far and near in the spatial position of the corresponding component relative to another component. In addition, the terms "first", "second", etc. used in the present disclosure are for distinguishing one element from another element, and do not have sequentiality and importance. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0029] Refer to Figures 1 to 4 , the present disclosure provides a seat belt suspension device, including a gantry 1, an embedded part 2 and a steel wire rope 3. Among them, the number of gantries 1 is set to at least two, the embedded part 2 is connected to the gantry 1 and buried underground, and the steel wire rope 3 is connected to two adjacent gantries 1 for suspending the seat belt.

[0030] Through the above technical solution, when the seat belt suspension device is applied to the opening of the tarpaulin on the top of the coal transport vehicle for coal transportation, the staff can wear the seat belt and suspend the seat belt on the steel wire rope 3 connected between two adjacent gantries 1. Compared with the related art in which the gantry 1 is erected on the ground through a cement pier or fixed to the ground through an expansion bolt, the gantry 1 of the present disclosure is connected with an embedded part 2 buried underground for fixation, improving the anti-movement and anti-tipping ability of the gantry 1, and thus ensuring the personal safety of the staff.

[0031] In some embodiments, refer to Figure 1 and Figure 2 , the gantry 1 may include a connected cross bar 11 and a vertical pole 12, and the embedded part 2 may include an embedded block 21 buried underground and a support 22 connected to the embedded block 21 by pouring. The support 22 is used to support the vertical pole 12. In this way, the steel wire rope 3 is connected to the cross bars 11 of two adjacent gantries 1, and the vertical pole 12 is connected to the support 22 for supporting the cross bar 11 and the steel wire rope 3. Among them, the embedded block 21 may be a concrete block. Exemplarily, a pit may be dug in advance for pouring the concrete block, and the support 22 is inserted into the concrete during the pouring process. After the concrete sets, the embedded block 21 is formed, and at this time, the support 22 and the embedded block 21 form a stable pouring connection.

[0032] It is understandable that, compared with directly connecting the vertical rod 12 to the embedded part 2, setting up the support 22 can save some materials of the vertical rod 12 to reduce costs. In addition, it is also convenient to replace the damaged vertical rod 12. At the same time, part or all of the support 22 can be buried underground to protect the support 22, reduce the possibility of the support 22 being damaged and deformed resulting in the deformation of the portal frame 1, and improve the safety of the staff during the operation process.

[0033] In some embodiments, referring to Figure 1 and Figure 3 , the vertical rod 12 can be configured as an octagonal rod. In this way, the geometric structure of the octagonal rod provides good mechanical properties, making the vertical rod 12 have high stability. At the same time, the octagonal rod can provide a larger surface area, which helps to improve the load-bearing capacity and torsional strength of the vertical rod 12, and thus can improve the anti-deformation ability of the vertical rod 12. In addition, the octagonal rod is also easy to install and maintain. For example, it is convenient for maintenance personnel to carry out inspections and cleaning, such as adjusting the angle of the vertical rod 12 or replacing the vertical rod 12. Of course, in some other possible implementation manners not shown in the drawings, the vertical rod 12 can also be configured as a circular rod or a square rod, and the present disclosure does not make specific limitations thereon.

[0034] In some embodiments, referring to Figure 1 and Figure 2 , the support 22 can include a threaded rod 221 and a support plate 222 connected to the threaded rod 221. Among them, the threaded rod 221 is connected to the embedded block 21 by pouring, and the vertical rod 12 is connected to the support plate 222 through a connector 4. In this way, through the support plate 222, the contact area can be increased to enhance the supporting ability for the vertical rod 12. During the process of connecting the support plate 222 to the threaded rod 221, the support plate 222 can be clamped and fixed by a pair of fastening nuts. Specifically, one of the fastening nuts can be first threadedly connected to the threaded rod 221, and then the support plate 222 is placed on this fastening nut. At this time, the threaded rod 221 can pass through the support plate 222. Finally, the other fastening nut is threadedly connected to the threaded rod 221 to abut against the support part. At this time, the two fastening nuts clamp and act on both sides of the support plate 222 to fix the support plate 222. In addition, the fastening nut and the support plate 222 can be welded and fixed subsequently to further improve the stability of the support plate 222 connected to the threaded rod 221, and the present disclosure does not make specific limitations thereon.

[0035] It can be understood that the number of the threaded rods 221 can be set to be multiple to improve the strength of the bracket 22, thereby improving the support stability for the vertical rod 12. Meanwhile, setting the threaded rods 221 facilitates the subsequent connection with the connecting member 4 (which will be described below). In some other possible embodiments not shown in the drawings, the bracket 22 may also include a support rod and a top plate. The support rod is connected to the embedded block 21 by casting, and the top plate is welded to the end of the support rod away from the embedding for connecting the vertical rod 12 through the connecting member 4. The present disclosure is not limited thereto.

[0036] In some embodiments, referring to Figure 1 and Figure 2 , the threaded rod 221 can pass through the support plate 222 and be flange-connected to the connecting member 4, and the vertical rod 12 can be flange-connected to the connecting member 4. Among them, the connecting member 4 can exemplarily include a support column and flange plates connected to opposite ends of the support column. In this way, during the connection process, the threaded rod 221 can pass through the support plate 222 and one of the flange plates of the connecting member 4, and is threadedly connected to the threaded rod 221 through a fastening nut and abuts against the flange plate to fix the flange plate and the support plate 222, thereby fixing the connecting member 4 to the bracket 22. The connection efficiency is improved through the threaded connection between the threaded rod 221 and the fastening nut, and then the vertical column is connected to the connecting member 4. Specifically, a flange plate can be welded at the bottom of the vertical column for flange connection with the other flange plate of the connecting member 4.

[0037] It can be understood that arranging the connecting member 4 between the bracket 22 and the vertical rod 12 facilitates the maintenance and replacement of the vertical rod 12. Meanwhile, both between the bracket 22 and the connecting member 4 and between the vertical rod 12 and the connecting member 4 are flange connections, having relatively high connection strength. At the same time, compared with directly connecting the vertical rod 12 to the bracket 22, the height of the connection point is higher, so the anti-deformation ability of the vertical rod 12 can be increased. Therefore, when the vertical rod 12 is impacted by a vehicle, for example, the vertical rod 12 is not easily deformed or damaged, improving the safety of the staff during the operation process.

[0038] In some embodiments, referring to Figure 1 and Figure 2, reinforcing ribs 5 can be provided at both the flange connection end of the support plate 222 and the flange connection end of the vertical rod 12 to the connecting member 4. In this way, the reinforcing ribs 5 can significantly improve the stiffness and strength of the flange connection, reduce deformation when bearing loads such as impacts, especially when the flange bears large radial or axial forces, the reinforcing ribs 5 can effectively disperse stress and reduce the possibility of deformation and damage of the vertical rod 12. In addition, the arrangement of the reinforcing ribs 5 helps to maintain the flatness and perpendicularity of the flange plane, ensuring the tight fit between the flanges. During the welding process of the flange connection, the reinforcing ribs 5 can provide additional support, helping to reduce welding deformation, making the welding more stable, improving the welding quality and the reliability of the connection. At the same time, the reinforcing ribs 5 can also reduce the stress concentration at the flange connection, improve the fatigue resistance of the vertical rod 12, and improve the durability of the vertical rod 12.

[0039] In some embodiments, referring to Figure 1 and Figure 3 , the vertical rod 12 may include a plurality of vertical rod segments 121 that are sequentially flange-connected through the flange portion 6. In this way, the height of the vertical rod 12 can be adjusted through the detachable connection of the plurality of vertical rod segments 121, so as to improve the applicability of the seat belt suspension device. For example, the vertical rod segments 121 can be installed and removed for different heights of the vehicle top to adjust the height of the cross bar 11 and the steel wire rope 3, thereby facilitating the operation of the staff. Among them, the flange portion 6 can be exemplarily constructed in the form of a combination connection of a sleeve and a flange plate. During the connection process of the vertical rod segments 121, the sleeve is sleeved on the end of the vertical rod segment 121, and the two flange plates are used for positioning and docking and subsequent bolt connection and fixation. It can be understood that the end of the vertical rod segment 121 connected to the bracket 22 close to the bracket 22 side can also use the flange portion 6 to replace the connecting member 4 to connect with the support plate 222, and the present disclosure does not make specific limitations on this.

[0040] In some embodiments, referring to Figure 1 and Figure 3, one of the vertical rod 12 and the cross rod 11 may have a connecting portion 7, the connecting portion 7 is flange-connected to the other of the vertical rod 12 and the cross rod 11 and is provided with a reinforcing rib 5. It can be understood that the flange connection has a relatively high connection strength and the connection process is relatively simple. Therefore, the cross rod 11 and the vertical rod 12 can be stably connected through the flange connection, and at the same time, the detachable connection between the vertical rod 12 and the cross rod 11 can be realized through the flange connection, which is convenient for the installation of the portal frame 1 and subsequent maintenance and replacement, etc. In one embodiment, the connecting portion 7 may be a connecting column welded to one end of the vertical rod section 121 and a flange plate formed at the other end of the connecting column. At the same time, the connecting portion 7 further includes a flange plate welded to one end of the cross rod 11 close to the vertical rod section 121, so as to realize the detachable connection between the cross rod 11 and the vertical rod 12 through the flange connection of the two flange plates. Of course, the reinforcing rib 5 can be connected to the vertical rod section 121, the connecting column and the flange plate by welding, so as to have the advantages of improving the stiffness and strength of the flange connection, effectively dispersing stress, and reducing the possibility of deformation and damage of the vertical rod section 121 and the cross rod 11. The present disclosure will not elaborate on this here.

[0041] In some embodiments, referring to Figure 1 and Figure 4 , the steel wire rope 3 is connected to two adjacent cross rods 11, and a limiting ring 8 through which the steel wire rope 3 can pass may be provided on the cross rod 11 to limit the movement of the steel wire rope 3 along the axial direction of the cross rod 11. Among them, in the process of connecting the steel wire rope 3 to the cross rods 11 of two adjacent portal frames 1, the steel wire rope 3 can be wound around the cross rod 11 circumferentially for at least one week and pass through the limiting ring 8, so as to be able to stop the movement of the steel wire rope 3 along the axial direction of the cross rod 11 through the limiting ring 8. In addition, sleeves or the like can also be welded to the cross rod 11 circumferentially for the end of the steel wire rope 3 to penetrate from one side of the sleeve and exit from the other side, so as to be able to limit the movement of the steel wire rope 3 along the axial direction of the cross rod 11. The present disclosure is not limited to this.

[0042] In some embodiments, referring to Figure 1 and Figure 4 , the free end of the steel wire rope 3 circumferentially surrounds the cross rod 11 and passes through the limiting ring 8 at least once, and the free end of the steel wire rope 3 and the middle section of the steel wire rope 3 are clamped and fixed by a rope buckle 9. In this way, the tension degree of the steel wire rope 3 can be adjusted by adjusting the clamping part of the steel wire rope 3 by the rope buckle 9, so that the steel wire rope 3 is in a taut state, so that the safety belt of the worker can move along the extending direction of the steel wire rope 3 during operation, reducing the jumping of the safety belt and the steel wire rope 3 in the height direction, and improving the safety of the worker during operation.

[0043] In addition, during the process of connecting the wire rope 3 to the cross bars 11 of two adjacent gantry frames 1, the wire rope 3 can first pass through the limit ring 8 and then be wound around the cross bar 11, or it can first be wound around the cross bar 11 and then pass through the limit ring 8. Of course, the wire rope 3 can also first pass through the limit ring 8, then be wound around the cross bar 11, and finally pass through the limit ring 8 again. The present disclosure is not limited thereto.
