Description

Technical Field

[0001] The present application relates to the technical field of stackers, and in particular to a high-altitude anti-fall protection safety mechanism. Background Art

[0002] At present, stacking cranes (referred to as stackers) refer to special cranes that use forks or skewer rods as picking devices to grab, transport and stack or pick and place unit goods from high-rise shelves in warehouses, workshops, etc. When inspecting or maintaining a stacker, operators need to climb the ladder on the side of the column to the top of the column to perform upper maintenance on the stacker, but the safety of the stacker is relatively low and operators are prone to falling accidents.

[0003] In the related art, a Chinese patent with publication number CN220223502U proposes to develop a high-altitude anti-fall protection safety mechanism, including a column, an upper fixed bracket, a lower fixed bracket, a soft steel wire rope and a wire rope gripper, the upper fixed bracket is fixed to the upper end of the column, the lower fixed bracket is fixed to the lower end of the column, the upper end of the soft steel wire rope is connected to the upper fixed bracket, the lower end of the soft steel wire rope is connected to the lower fixed bracket, the soft steel wire rope passes through the wire rope gripper, a ladder is fixed to the side of the column along the vertical direction, a protective cage is arranged around the outer side of the ladder, a cage steel platform is fixed to the upper end of the protective cage, and an upper entry and exit door is hinged in the middle of the cage steel platform. The safety rope of the high-altitude workers on the high-altitude anti-fall protection safety mechanism can be connected to the wire rope gripper, and when moving up and down, it will automatically lock on the soft steel wire rope when it suddenly stalls, protecting the personnel from falling.

[0004] The above-mentioned related technologies have the following defects: the space on the steel platform is small. After the workers pass through the upper entrance door to enter the steel platform, they need to flip the hinged upper entrance door, which makes it very inconvenient for the workers to move and turn around, especially when carrying work tools during work, which is not conducive to the workers safely reaching the top of the steel platform to perform work. Utility Model Content

[0005] In order to improve the problem that the hinged upper entry and exit doors on the steel platform affect the workers' crossing of the steel platform, the present application provides a high-altitude fall prevention safety mechanism.

[0006] The high altitude fall protection safety mechanism provided in this application adopts the following technical solution:

[0007] A high-altitude anti-fall protection safety mechanism comprises a column, a guardrail ladder, a wire rope, a wire rope gripper and a protection platform, wherein the guardrail ladder is vertically arranged on one side of the column, and an upper hook and a lower hook are respectively fixedly connected at the upper and lower ends of one side of the guardrail ladder, and the wire rope is fixed to the guardrail ladder through the upper and lower hooks, and the wire rope passes through the wire rope gripper; the protection platform is fixed to the upper end of the guardrail ladder, and an inlet and outlet are provided on the side of the protection platform close to the column, and two parallel slide rails are fixedly connected to the lower end surface of the protection platform, and the slide rails extend in a direction away from the column, and sliding doors parallel to the protection platform are commonly provided on the two slide rails for anti-slip sliding.

[0008] Furthermore, the upper end surface and the lower end surface of the sliding door close to the column are respectively fixed with handles.

[0009] Furthermore, the sliding door is provided with a support block protruding from one side of the handle close to the column and extending toward the column, and a support platform corresponding to the support block is fixedly connected to the column, and when the sliding door closes the entrance and exit, the support block is embedded in the support platform.

[0010] Furthermore, a rubber pad is arranged under the support block, and a notch is provided on the support platform; when the support block is embedded in the notch, the rubber pad is pressed tightly.

[0011] Furthermore, a limiter is provided at one end of the slide rail away from the column to prevent the sliding door from falling off the slide rail.

[0012] Furthermore, the slide rail is coated with a grease layer.

[0013] Furthermore, the upper hook is bent upward, the lower hook is bent downward, the upper end of the steel wire rope is buckled on the upper hook, and the lower end of the steel wire rope is buckled on the lower hook.

[0014] In summary, the beneficial technical effects of this application are:

[0015] When climbing, the operator installs the safety buckle on his own safety belt on the wire rope gripper. When the operator falls accidentally, the wire rope gripper will lock on the wire rope to keep the operator in the current position and prevent it from falling, thereby realizing the anti-fall safety protection for the operator. After the operator reaches the top of the guardrail ladder, the operator can push the handle to make the sliding door away from the entrance and exit, and then enter the protection platform through the sliding door. After the operator passes through the entrance and exit, the operator pushes the sliding door with the handle to close the entrance and exit, making it easier for the operator to reach the protection platform; and in this process, the sliding door will not affect the range of activities of the operator passing through the entrance and exit to the protection platform. The operator can freely turn around, move, etc., which is safer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0021] The present application embodiment discloses a high altitude fall protection safety mechanism. Figure 1 and Figure 2A high altitude anti-fall protection safety mechanism comprises a column 1, a guardrail ladder 2, a wire rope 31, a wire rope gripper 31 and a protection platform 4. The guardrail ladder 2 is vertically arranged on one side of the column 1. An upper hook 32 and a lower hook 33 are respectively fixedly connected to the upper and lower ends of one side of the guardrail ladder 2. The wire rope 31 is fixed to the guardrail ladder 2 through the upper hook 32 and the lower hook 33, and the wire rope 31 passes through the wire rope gripper 31. A horizontally arranged protection platform 4 is fixed to the upper end of the guardrail ladder 2. An inlet and outlet 41 is provided through the side of the protection platform 4 close to the column 1. Two parallel slide rails 5 are fixedly connected to the lower end surface of the protection platform 4. The two slide rails 5 are arranged on opposite sides of the inlet and outlet 41. The extension direction of the slide rails 5 is arranged in a direction away from the column 1. A sliding door 6 parallel to the protection platform 4 is provided on the two slide rails 5 for anti-slip sliding. The sliding door 6 is attached to the lower end surface of the protection platform 4.

[0022] In this way, when the operator is climbing, he first installs the safety buckle on his own safety belt on the wire rope gripper 31, and then he can climb up along the guardrail ladder 2. The guardrail on the guardrail ladder 2 can effectively prevent the operator from falling due to loss of balance during the climbing process; even when the operator falls accidentally, the wire rope gripper 31 will be locked on the wire rope 31 to keep the operator in the current position without falling, thereby realizing the anti-fall safety protection for the operator. After the operator reaches the top of the guardrail ladder 2, the operator can push the handle 61 to make the sliding door 6 away from the entrance 41, and then enter the protection platform 4 through the sliding door 6. After the operator passes through the entrance 41, the sliding door 6 is pushed by the handle 61 to close the entrance 41, so that the operator can reach the protection platform 4 more conveniently; and in this process, the sliding door 6 will not affect the range of activities of the operator passing through the entrance 41 to the protection platform 4, and the operator can freely turn around, move, etc., which is safer.

[0023] Specifically, refer to Figure 1 and Figure 2 The upper end surface and the lower end surface of the sliding door 6 close to the column 1 are fixedly connected with handles 61 , which facilitate the operator to open the sliding door 6 and limit the sliding door 6 .

[0024] Further, refer to Figure 2 and Figure 3 A support block 62 extending toward the column 1 is protruded from the handle 61 of the sliding door 6 on one side close to the column 1, and a support platform 11 corresponding to the support block 62 is fixedly connected to the column 1. When the sliding door 6 closes the inlet and outlet 41, the support block 62 is embedded in the support platform 11. Specifically, a rubber pad 621 is fixedly connected to the lower end surface of the support block 62, and a corresponding notch 111 is provided on the support platform 11; when the support block 62 is embedded in the notch 111, the rubber pad 621 is pressed tightly.

[0025] In this way, when the operator enters the top of the protective platform 4, he pushes the sliding door 6 so that the support block 62 is embedded in the notch 111 of the base 11. At this time, the rubber pad 621 is pressed tightly to increase the static friction between the support block 62 and the base 11, which can prevent the sliding door 6 from sliding on the slide rail 5 independently, thereby effectively preventing the operator from accidentally pushing open the sliding door 6 on the protective platform 4 and causing it to fall, and the overall stability of the protective platform 4 can be maintained.

[0026] In another possible implementation, referring to Figure 3 , the thickness of the rubber pad 621 close to the base 11 is set to be greater than the thickness of the rubber pad 621 away from the base 11, and the groove depth corresponding to the notch 111 is also set so that the groove depth close to the column 1 is greater than the groove depth away from the column 1. In this way, after the support block 62 is pushed by the operator to be embedded in the notch 111 of the base 11, a certain locking structure can be formed, which can further improve the anti-self-slip effect of the sliding door 6.

[0027] And, refer to Figure 2 A stopper 51 is provided at one end of the slide rail 5 away from the column 1 to prevent the sliding door 6 from escaping from the slide rail 5, further avoiding the sliding door 6 from escaping from the slide rail 5 and causing an accident. In addition, a grease layer is coated on the slide rail 5 to facilitate the sliding of the sliding door 6 on the slide rail 5 and facilitate the operation of the operator.

[0028] In addition, refer to Figure 1 The upper hook 32 is bent upward, and the lower hook 33 is bent downward. The upper end of the wire rope 31 is buckled on the upper hook 32, and the lower end of the wire rope 31 is buckled on the lower hook 33. Under the action of the upper hook 32 and the lower hook 33, the wire rope 31 is straightened and it is convenient for operators to climb.

[0029] The implementation principle of a high altitude fall protection safety mechanism in the embodiment of the present application is:

[0030] When the operator is climbing, he / she installs the safety buckle on his / her own safety belt on the wire rope gripper 31. When the operator falls accidentally, the wire rope gripper 31 will be locked on the wire rope 31 to keep the operator in the current position and prevent it from falling, thereby realizing the anti-fall safety protection for the operator. After the operator reaches the top of the guardrail ladder 2, the operator can push the handle 61 to make the sliding door 6 away from the entrance 41, and then enter the protection platform 4 through the sliding door 6. After the operator passes through the entrance 41, the operator pushes the sliding door 6 through the handle 61 to close the entrance 41, so that the operator can reach the protection platform 4 more conveniently; and in this process, the sliding door 6 will not affect the range of activities of the operator passing through the entrance 41 to the protection platform 4, and the operator can freely turn around, move, etc., which is safer.
