Description
Technical Field
[0001] This utility model relates to the field of elevator anti-collision, specifically an anti-collision structure for construction elevators. Background Technology
[0002] As a common vertical transportation equipment, hoists are widely used in various fields such as construction, cargo handling, and personnel transportation. In the construction process, construction hoists, also known as construction elevators, are frequently used construction machinery for carrying people and goods. On construction sites, they are usually used in conjunction with tower cranes for vertical transportation of materials and personnel. As permanent or semi-permanent elevators, they can also be used in warehouses, high towers, and other places. They generally consist of a bottom railing, guide rail frame, transmission device, cage, and other devices.
[0003] When the electrical control system malfunctions or there are temporary obstacles in the shaft, the hoist cage is very likely to have a rigid collision with the shaft structure or the obstacle. This can not only cause deformation of the hoist cage structure and damage to the equipment, but may also lead to major safety accidents such as the hoist cage falling and casualties.
[0004] Generally, the hoist cage is equipped with anti-collision devices (such as anti-collision steel plates) on the bottom of the outside, but there are some drawbacks: when the collision speed is high or the impact force is large, relying solely on the anti-collision steel plates makes the anti-collision protection effect of the hoist poor. In addition, the anti-collision devices are generally fixed at the bottom of the cage and cannot protect against the risk of collisions on the left and right sides and the top. Therefore, in order to address the above problems, an anti-collision structure for construction hoists is proposed. Summary of the Invention
[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes an anti-collision structure for construction hoists.

[0020] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses an anti-collision structure for a construction hoist. (Refer to...) Figures 1-5 A collision avoidance structure for a construction hoist includes a support base 1; an electrical control box is fixedly mounted on the support base 1, containing a PLC controller that is electrically connected to the electrical components in the device; a fixed tower 2 is fixedly mounted above the support base 1, the fixed tower 2 being made of high-strength steel and coated with a protective layer; a lifting mechanism is located above the fixed tower 2, used to lift a hoisting car 5; a set of side guide rails 3 are parallel to the front of the fixed tower 2, with slides 4 slidably connected to the side guide rails 3; a hoisting car 5 is fixedly mounted on the front side of the two slides 4; a steel door 6, made of high-strength steel, is hinged to the front side of the hoisting car 5, and has a relatively high safety feature. Good impact resistance: The upper part of the hoisting box 5 is equipped with an upper anti-collision mechanism to protect the upper part of the hoisting box 5. A connector 7 is fixedly installed on the upper anti-collision mechanism. The lower part of the hoisting box 5 is equipped with a lower anti-collision mechanism to protect the lower side of the hoisting box 5. Side anti-collision mechanisms are fixedly installed on both sides of the hoisting box 5 to protect the sides of the hoisting box 5. Rubber strips 8 are installed at the side edges of the hoisting box 5. Angle plates 9, made of high-quality steel, are fixedly installed on the outer side of the rubber strips 8 to protect the side edges of the hoisting box 5.
[0021] Reference Figure 1 The lifting mechanism includes a support platform 10 fixedly installed above the fixed tower 2. A winding roller 11 is rotatably installed on the support platform 10. A motor 12 is installed on one side of the support platform 10. The output end of the motor 12 is connected to the shaft end of the winding roller 11 on one side. A steel wire rope 13 is wound on the winding roller 11. One end of the steel wire rope 13 is fixedly connected to the connector 7. The motor 12 is a high-load servo motor that can achieve forward and reverse rotation and stable operation. Through the structural setting of the lifting mechanism, the hoisting box 5 is lifted and lowered.
[0022] Reference Figure 1 and Figure 3 An auxiliary slide bar 14 is fixedly installed on the front side of the fixed tower 2. The auxiliary slide bar 14 is located between the two side guide rails 3. A set of rod sleeves 15 is installed at the rear of the hoisting box 5. The two rod sleeves 15 are slidably connected to the auxiliary slide bar 14. This structure improves the stability of raising and lowering the hoisting box 5.
[0023] Reference Figure 1 and Figure 2The upper anti-collision mechanism includes a lower plate 16 fixedly installed above the hoisting box 5. A first rubber pad 17 is embedded in the bottom of the lower plate 16. Multiple reinforcing corner brackets 18 are fixedly installed above the lower plate 16. An upper plate 19 is fixedly installed above the multiple reinforcing corner brackets 18. Through this structure, the upper part of the hoisting box 5 can be protected, and the impact resistance of the upper part of the hoisting box 5 can be improved.
[0024] Reference Figure 1 and Figure 5 The side impact protection mechanism includes a second rubber pad 20 fixedly installed on the side of the hoisting box 5. Multiple honeycomb buffer grooves 21 are evenly opened on the second rubber pad 20. A side protection plate 22 is fixedly installed on the outer side of the second rubber pad 20. Through this structure, the side of the hoisting box 5 can be protected. By opening the honeycomb buffer grooves 21 on the second rubber pad 20, the impact force can be effectively absorbed. The side protection plate 22 is a steel plate, and multiple reinforcing plates are fixedly installed on the outer side of the side protection plate 22 to improve the impact resistance of the side protection plate 22.
[0025] Reference Figure 1 and Figure 3 The lower anti-collision mechanism includes buffer blocks 23 fixedly installed at the four corners below the suspended box 5. Multiple lower slot seats 24 are evenly arranged below the suspended box 5. Slot frames 25 are slidably connected to the lower slot seats 24. Springs 26 are installed in the lower slot seats 24. The lower end of the springs 26 is connected to the lower inner side of the slot frames 25. Bottom protective plates 27 are fixedly installed below the multiple slot frames 25. Through the structural design of the lower anti-collision mechanism, the lower part of the suspended box 5 is effectively protected. When the lower part of the suspended box 5 is impacted, the bottom protective plate 27 protects the lower part of the suspended box 5. The slot frames 25 above the bottom protective plate 27 are impacted, causing the multiple slot frames 25 to slide on the corresponding lower slot seats 24. The springs 26 in the lower slot seats 24 are compressed to buffer the impact force. The buffer blocks 23 are rubber blocks, which can buffer and support the bottom protective plate 27.
[0026] Reference Figure 3 A lower buffer pad 28 is fixedly installed below the bottom protective plate 27, and multiple buffer protrusions are fixedly installed below the lower buffer pad 28. This structure improves the protective performance of the bottom protective plate 27.
[0027] Working principle: The lifting mechanism raises and lowers the hoisting box 5. By controlling the operation of the motor 12, the winding roller 11 rotates on the support 10. At this time, the steel wire rope 13 is wound on the winding roller 11, thereby pulling the connecting piece 7 upward. This causes the slide 4 on the hoisting box 5 to slide on the guide rail 3, and the sliding sleeve 15 at the rear of the hoisting box 5 slides on the auxiliary slide rod 14, improving the stability of raising and lowering the hoisting box 5. The upper anti-collision mechanism can protect the upper part of the hoisting box 5 and improve its impact resistance. The lower plate 16, the upper plate 19, and the reinforcing corner frame 18 form an "impact-resistant plate" structure. The reinforcing corner frame 18 forms multiple triangular grooves between the upper plate 19 and the lower plate 16, which reduces the overall weight of the "impact-resistant plate" and effectively improves its impact resistance. Furthermore, a first rubber pad 17 is embedded at the bottom of the lower plate 16 to further enhance the impact resistance of the upper part of the hoisting box 5. The side impact protection mechanism can protect the side of the cradle 5. The honeycomb buffer groove 21 on the second rubber pad 20 can effectively absorb the impact. The side protection plate 22 is made of steel plate, and multiple reinforcing plates are fixed on the outside of the side protection plate 22 to improve the impact resistance of the side protection plate 22. The lower anti-collision mechanism effectively protects the bottom of the cradle 5. When the bottom of the cradle 5 is impacted, the bottom protective plate 27 protects the bottom of the cradle 5. When the slot frame 25 above the bottom protective plate 27 is impacted, multiple slot frames 25 slide on the corresponding lower slot seat 24, and the spring 26 in the lower slot seat 24 is compressed to buffer the impact force. The buffer block 23 is a rubber block that can buffer and support the bottom protective plate 27. A lower buffer pad 28 is fixedly installed below the bottom protective plate 27, and multiple buffer protrusions are fixedly installed below the lower buffer pad 28. Through this structural design, the protective performance of the bottom protective plate 27 is improved. Rubber strips 8 are installed on the side edges of the hoisting box 5, and corner plates 9 are fixed on the outside of the rubber strips 8. The corner plates 9 are made of high-quality steel. This structure protects the side edges of the hoisting box 5.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
