Description

Technical Field

[0001] This utility model relates to the field of tower crane technology, specifically to an inclined ladder for tower cranes. Background Technology

[0002] Existing tower cranes typically use inclined ladders, which are at an angle to the horizontal. Workers can move upwards by holding onto handrails and stepping on the ramps. However, the ramps on existing inclined ladders are usually horizontal. Drainage holes are drilled through the top of the ramps to clean up rainwater that accumulates there. However, some rainwater still accumulates between adjacent drainage holes, causing workers' shoes to slip when placed on the ramps, increasing the probability of accidents. Existing anti-slip measures usually involve raised rings at the top of the ramps to increase friction between the soles of the shoes and the ramps. However, the friction between the rings and the soles of the shoes is relatively low and cannot effectively prevent slipping. Workers holding onto the handrails are also prone to slipping their hands.

[0003] Therefore, a slanted ladder for tower cranes is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an inclined ladder for tower cranes, which can solve the problems of incomplete drainage of water accumulated at the top of the steps, low friction between shoe soles and steps, and easy slippage of the handrails.

[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes a ladder body and two support platforms fixedly connected to the inner side of the ladder body. One of the support platforms is provided with at least two handrails on one side, and several treads are provided between the two handrails. The upper and lower halves of the two handrails are both provided with fixed rods, which are fixedly connected to the handrails. Fixed blocks are fixedly connected to both ends of the two fixed rods. Several diamond-shaped blocks are fixedly connected to the upper ends of the several treads.

[0006] Preferably, all of the rhombus blocks are rhombus-shaped, the rhombus blocks located on the same horizontal direction are equidistantly distributed, and the rhombus blocks located on different horizontal directions are staggered vertically.

[0007] Preferably, the overall length of the rhombus block is X, where 5cm > X > 3cm, and the overall width of the rhombus block is Y, where 3cm > Y > 2cm.

[0008] Preferably, the pedal is inclined, and the angle between the pedal and the horizontal plane is α, where 5° > α > 3°.

[0009] Preferably, a plurality of anti-slip grips are fixedly connected to the outer sides of both handrails. A plurality of arc-shaped grooves are provided on the outer side of the anti-slip grips. The plurality of arc-shaped grooves are symmetrically distributed, and one of the arc-shaped grooves is centrally symmetrical with the other arc-shaped grooves.

[0010] Preferably, the depth of the arc-shaped groove is defined as h, and 4cm > h > 3cm.

[0011] Preferably, the two fixing blocks in the lower half are fixedly connected to the inner side of the support platform, and the two fixing blocks in the upper half are fixedly connected to the inner side of the ladder body.

[0012] Compared with the prior art, this utility model provides an inclined ladder for tower cranes, which has the following features:

[0013] Beneficial effects:

[0014] 1. By setting the pedal to an inclined shape and installing a diamond-shaped block at the top of the pedal, rainwater is prevented from accumulating at the top of the pedal and the friction between the sole of the shoe and the pedal is increased, thus improving safety.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1 - Figure 5 The inclined ladder for a tower crane in this embodiment includes a ladder body 1 and two support platforms 2 fixedly connected to the inner side of the ladder body 1. At least two handrails 3 are provided on one side of one of the support platforms 2, and several treads 4 are provided between the two handrails 3. Fixed rods 5 are provided through the upper and lower halves of the two handrails 3. The fixed rods 5 are fixedly connected to the handrails 3. Fixed blocks 6 are fixedly connected to both ends of the two fixed rods 5. Several diamond-shaped blocks 7 are fixedly connected to the upper ends of the several treads 4.

[0025] Several rhombus-shaped blocks 7 are all rhombus-shaped. Rhombus-shaped blocks 7 located on the same horizontal direction are equidistantly distributed, while rhombus-shaped blocks 7 located on different horizontal directions are staggered vertically.

[0026] The overall length of rhombus 7 is X, and 5cm > X > 3cm; the overall width of rhombus 7 is Y, and 3cm > Y > 2cm.

[0027] The pedal 4 is inclined, and the angle between the pedal 4 and the horizontal plane is α, where 5° > α > 3°.

[0028] In this embodiment, the position of the support platform 2 is fixed by the ladder body 1, and the support platform 2 can support the staff at the upper end. By setting the step 4 between the two handrails 3, the step 4 can provide support for the staff, and the staff can move upward along the handrails 3. Since the step 4 supports the staff and the staff can move upward along the handrails 3, these are existing technologies and therefore are not described in detail in this embodiment.

[0029] At this time, the staff member stands on the support platform 2 located below. The staff member can grasp the anti-slip component set on the outside of the handrail 3 with both palms. When the two palms are firmly gripping the anti-slip component, the staff member places the foot on the upper end of the pedal 4 and moves the foot up the upper end of the pedal 4. The staff member can grasp the anti-slip component with both palms to achieve the effect of moving upward. Several diamond blocks 7 are fixedly connected to the upper end of the pedal 4 and the diamond blocks 7 located at different horizontal levels are set to be staggered vertically. The sharp edges of the diamond blocks 7 can be embedded in the grooves of the shoe sole pattern to form a mechanical interlock, preventing the shoe sole from sliding relative to the surface of the pedal 4. The gaps between the diamond blocks 7 can accommodate the protrusions of the shoe sole pattern, so that when the two come into contact, the protrusions are locked into the grooves, increasing the mechanical locking effect of the contact point. By limiting the angle of the pedal 4, when it is rainy, rainwater will slide to the tilted side when it falls into the upper end of the pedal 4, preventing the rainwater from accumulating on the upper end of the pedal 4 and causing the staff member to fall off during the movement.

[0030] The rhombus structure of the rhombus block 7 has bidirectional symmetry. Regardless of whether the worker's shoe sole tends to slide along the length or width of the pedal 4, the acute edges of the rhombus block 7 can effectively counteract the grooves of the shoe sole pattern, increasing the friction between the pedal 4 and the shoe sole. This improves worker safety and prevents slippage and injury when the worker moves on the pedal 4. By setting the shape of the rhombus block 7 to rhombus, regardless of whether the contact object slides along the length, width, or diagonal direction, a certain set of edges of the rhombus block 7 can always interact with the contact object. The textured surface of the contact surface effectively counteracts the slip, avoiding the limitations of unidirectional anti-slip and comprehensively improving the practicality of friction. The length and width of the diamond block 7 are limited to better match the texture of the shoe sole, preventing the diamond block 7 from being too large or too small, which would prevent it from effectively increasing the friction with the shoe sole. By fixing the fixing rod 5 to the handrail 3 and fixing the position of the handrail 3 with the fixing block 6, the handrail 3 can be fixed to prevent it from wobbling when the staff moves upward while holding it, thus improving the stability of the structure.

[0031] Several anti-slip grips 8 are fixedly connected to the outer sides of both handrails 3. Several arc-shaped grooves 9 are opened on the outer side of the anti-slip grips 8. The arc-shaped grooves 9 are symmetrically distributed, and one arc-shaped groove 9 is centrally symmetrical with the other arc-shaped grooves 9.

[0032] The depth of the arc groove 9 is defined as h, and 4cm > h > 3cm;

[0033] The two fixing blocks 6 in the lower half are fixedly connected to the inside of the support platform 2, and the two fixing blocks 6 in the upper half are fixedly connected to the inside of the ladder body 1;

[0034] Specifically, by setting an anti-slip grip 8 on the outside of the handrail 3, and opening several arc-shaped grooves 9 on the outside of the anti-slip grip 8, when the staff grabs the anti-slip grip 8, the staff's fingers will enter the inside of the arc-shaped grooves 9. When the gripping force is applied, the protruding structure is embedded into the gaps or textures of the object being grabbed, increasing the mechanical friction of the contact surface. The staggered distribution of the contact points can adapt to the surface shape of the object being grabbed. The mechanical locking effect is enhanced through multi-point interlocking, which improves the stability of the grip. By limiting the depth of the arc-shaped grooves 9, it can be ensured that the arc-shaped grooves 9 can limit the size of fingers of different sizes, thus improving the versatility of the anti-slip grip 8.

[0035] The working principle of the above embodiments is as follows:

[0036] When in use, the worker stands on the support platform 2 located below. The worker can grip the anti-slip parts on the outside of the handrail 3 with both hands. When both hands are firmly gripping the anti-slip parts, the worker places their feet on the pedal 4 and moves their feet upwards on the pedal 4. The worker can then grip the anti-slip parts upwards with both hands to achieve the effect of moving upwards. The diamond-shaped block 7 at the top of the pedal 4 increases the friction between the pedal 4 and the sole of the shoe, preventing slippage during movement. The anti-slip grip sleeve 8 on the outside of the handrail 3 increases the friction between the hands and the handrail 3, preventing the hands from slipping off when gripping the handrail 3. The inclined design of the pedal 4 prevents rainwater from accumulating on the top of the pedal 4.

[0037] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
