Description

Technical Field

[0001] This invention relates to the field of tank loading and unloading technology, and in particular to a tank-side loading safety belt bracket. Background Technology

[0002] In the petrochemical, logistics, and transportation industries, workers frequently need to climb to the tops of tank trucks, oil tankers, and other tank vehicles to load, unload, sample, inspect, or clean. The tops of tank trucks are high above the ground, falling into the category of high-altitude work and posing a significant risk of fall. To ensure the safety of workers, safety belts must be provided with secure and reliable anchor points during such high-altitude operations.

[0003] However, the top of tank trucks is typically a smooth, curved surface, lacking natural, stable anchor points for seat belts. To address this, the industry has developed specialized "tank-side loading seat belt hangers." These hangers are usually secured to the edge of the tank truck's top or walkway using a clamping or hooking mechanism, providing workers with a temporary, elevated safety attachment point above the work surface.

[0004] Existing racks are generally fixed to the ground, which poses a risk of tipping over if workers move too much. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a tank-side loading safety belt bracket that can be connected to a tank truck to reduce the risk of tipping over.

[0006] According to an embodiment of the present invention, a tank-side loading safety belt hanger includes a frame, a ladder, a hanger, and a front fork. The ladder is mounted on the frame and configured to allow workers to climb to the top of the tank. The hanger is connected to the frame and located directly above the ladder's Z-axis, and is configured to hook a safety belt. The front fork is connected to the frame and includes a first fork wall and a second fork wall, which are configured to insert into the bottom of the tank truck and clamp the tires to prevent the frame from tipping over.

[0007] It has at least the following beneficial effects: by setting the bracket directly above the Z-axis of the ladder, the safety belt can be attached to the workers when they are working on the top of the tanker truck, reducing the risk of falling; at the same time, the first and second fork walls of the front fork can be inserted into the bottom of the tanker truck and clamp the tires, so that the entire frame is stably connected to the tanker truck, effectively preventing the frame from tipping over due to external forces or personnel movements, and improving the safety of high-altitude operations.

[0008] According to some embodiments of the present invention, a fork adjustment device is also included, the fork adjustment device being connected to the frame and the fork, the fork adjustment device being configured to adjust the width of the fork and the length of the fork extending out of the frame along the X-axis direction.

[0023] Reference Figure 1 and Figure 2 This invention discloses a tank-side loading safety belt hanger, including a frame 10, a ladder 20, a hanger 30, and a front fork 40. The ladder 20 is mounted on the frame 10 and is configured to allow workers to climb to the top of the storage tank. The hanger 30 is connected to the frame 10 and is located directly above the Z-axis of the ladder 20. The hanger 30 is configured to attach a safety belt. The front fork 40 is connected to the frame 10 and includes a first fork wall 41 and a second fork wall 42. The first fork wall 41 and the second fork wall 42 are configured to insert into the bottom of the tank truck and clamp the tires to prevent the frame 10 from tipping over.

[0024] Understandably, by setting the hanger 30 directly above the Z-axis of the ladder 20, the safety belts of the workers can be attached when working on the top of the tanker truck, reducing the risk of falling. At the same time, the first fork wall 41 and the second fork wall 42 of the front fork 40 can be inserted into the bottom of the tanker truck and clamp the tires, so that the entire frame 10 is stably connected to the tanker truck, effectively preventing the frame 10 from overturning due to external forces or personnel movements, and improving the safety of high-altitude operations.

[0025] Reference Figure 1 and Figure 2 A can-side loading seat belt bracket also includes a fork adjustment device 50, which connects the frame 10 and the fork 40. The fork adjustment device 50 is configured to adjust the width of the fork 40 and the length of the fork 40 extending out of the frame 10 along the X-axis.

[0026] It is understood that, in the embodiments of the present invention, by setting the front fork adjustment device 50, the extension length and width of the front fork 40 can be flexibly adjusted according to the actual position and size of the tank truck tire, so that the bracket is suitable for different models of tank trucks and tire specifications, thereby enhancing the versatility and adaptability of the equipment.

[0027] Reference Figure 2 The fork adjustment device 50 includes a length adjustment mechanism 51 and a width adjustment mechanism 52. The length adjustment mechanism 51 is connected to the frame 10 and is configured to adjust the length of the fork 40 extending out of the frame 10 along the X-axis direction. The width adjustment mechanism 52 is connected to the length adjustment mechanism 51 and is configured to adjust the width of the fork 40 to accommodate different sizes of tank tires.

[0028] It is understood that, in the embodiments of the present invention, the adjustment function is decomposed into an independent length adjustment mechanism 51 and a width adjustment mechanism 52, so that the position adjustment of the fork 40 in the X-axis direction and the width adjustment in the Y-axis direction can be performed separately, making the operation more targeted and the adjustment process more precise and efficient, ensuring that the fork 40 can accurately match the installation position and size of different tank tires.

[0029] Reference Figure 2 The length adjustment mechanism 51 includes a first lead screw 511, a first threaded sleeve 512, a mounting rod 513, a guide rod 514, and a guide sleeve 515. The first lead screw 511 is rotatably connected to the frame 10 and extends along the X-axis. The first threaded sleeve 512 is threadedly connected to the first lead screw 511. Rotation of the first lead screw 511 drives the first threaded sleeve 512 to move along the X-axis. The mounting rod 513 is connected to the first threaded sleeve 512 and extends along the Y-axis. The guide rod 514 is disposed on the frame 10 along the X-axis. The guide sleeve 515 is disposed at both ends of the mounting rod 513 and is slidably connected to the guide rod 514. The front fork 40 is connected to the mounting rod 513. Rotation of the first lead screw 511 can drive the front fork 40 to move along the X-axis.

[0030] It is understood that, in the embodiments of the present invention, the transmission method of the first lead screw 511 and the first threaded sleeve 512 can realize the precise and stable displacement of the front fork 40 in the X-axis direction; the sliding connection structure of the guide rod 514 and the guide sleeve 515 provides reliable guidance for the movement of the mounting rod 513 and the front fork 40, prevents swaying, ensures that the length adjustment process is stable and smooth, and the position is self-locking after adjustment, so that it will not be accidentally displaced due to vibration or other reasons.

[0031] Reference Figure 2 The width adjustment mechanism 52 includes a sliding sleeve 521, a second threaded sleeve 522, and a second lead screw 523. The sliding sleeve 521 is slidably sleeved on the mounting rod 513. There are two sets of sliding sleeves 521, which are symmetrically arranged along the midpoint of the length direction of the mounting rod 513. The first fork wall 41 and the second fork wall 42 are respectively connected to one set of sliding sleeves 521. There are two sets of second threaded sleeves 522, which are respectively connected to the sliding sleeves 521. The second lead screw 523 is connected to the two sets of second threaded sleeves 522. The rotation direction of the thread on the second lead screw 523 is symmetrical along the midpoint of its length direction. When the second lead screw 523 is rotated, the two sets of second threaded sleeves 522 drive the first fork wall 41 and the second fork wall 42 to move closer to each other or further away from each other.

[0032] It should be noted that the threads at both ends of the second lead screw 523 rotate in opposite directions. By setting a second lead screw 523 with symmetrical threads, and cooperating with two sets of symmetrically arranged sliding sleeves 521 and second threaded sleeves 522, when the second lead screw 523 is rotated, the first fork wall 41 and the second fork wall 42 can move synchronously towards or away from each other, realizing symmetrical adjustment of the width of the front fork 40, ensuring balanced force when clamping the tire, and improving clamping stability and adaptability to different tire widths.

[0033] Reference Figure 2 The first lead screw 511 is connected to a first drive device 60 at its end, and the first drive device 60 is configured to drive the first lead screw 511 to rotate.

[0034] It is understood that, in the embodiments of the present invention, by setting the first driving device 60 to provide power for the rotation of the first lead screw 511, the length adjustment operation is made easier and more convenient, especially suitable for working conditions that require frequent adjustment or have high adjustment resistance, thus improving the ease of operation of the equipment.

[0035] Reference Figure 2 The first driving device 60 is a crank.

[0036] It is understood that in the embodiments of the present invention, a crank is used as the first driving device 60, which has a simple and reliable structure, does not require external energy such as electricity, is suitable for use in outdoor occasions where power may be lacking, such as tank truck loading and unloading, and is intuitive to operate and has low maintenance costs.

[0037] Reference Figure 2 The second lead screw 523 is connected to a second drive device 70 at its end, and the second drive device 70 is configured to drive the second lead screw 523 to rotate.

[0038] It is understood that, in the embodiments of the present invention, by setting a second driving device 70 to provide a dedicated driving force for the rotation of the second lead screw 523, the width adjustment operation and the length adjustment operation can be performed independently and conveniently, further optimizing the human-computer interaction experience.

[0039] Reference Figure 2 The second drive device 70 is a crank.

[0040] It is understood that in the embodiments of the present invention, a crank handle is also used as the second driving device 70, which maintains the advantage that the device as a whole does not require external power. The operator can easily control the width of the front fork 40 by manually cranking it, and the adjustment process is safe and controllable.

[0041] It should be noted that, in some embodiments of the present invention, the first drive device 60 and the second drive device 70 may also be electrically driven tools such as servo motors or other tools capable of outputting torque such as engines.

[0042] Reference Figure 2 The bottom of the frame 10 is equipped with several casters 80.

[0043] It is understood that, in the embodiments of the present invention, a movable wheel 80 is provided at the bottom of the frame 10, so that the entire hanging device can be easily moved and positioned within the work site, facilitating rapid transfer between different tank trucks or work points, significantly improving work efficiency and reducing the labor intensity of personnel handling.
