Description

Technical Field

[0001] The utility model relates to the technical field of elevator hoistway frames, and particularly to a hanging type outer surrounding member for elevator hoistway frame columns. Background Technique

[0002] The elevator hoistway frame column is the main load-bearing structure in the elevator hoistway. It supports the elevator car and the counterweight system to ensure the smooth and safe operation of the elevator. The column is usually made of steel because steel has high strength and good durability. The application number is retrieved as CN202222306020.4, a shielding door column cladding plate, which sprays an insulating coating on the outer surface of the polyurethane waterproof layer to form a sprayed insulating layer, further improving the insulation of the surface of the polyurethane insulation board and cooperating with the polyurethane insulation board to play a dual insulation role.

[0003] Similar to the above shielding door column cladding plate: Although an insulating coating is sprayed on the outer surface of the polyurethane waterproof layer to form a sprayed insulating layer, further improving the insulation of the surface of the polyurethane insulation board, but firstly, most of the current outer surrounding members are fixed by bolts, and there will be traces of punching, bolts and welding on the outer wall after installation, which affects the appearance. Secondly, there is no buffer mechanism for buffering when being bumped.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a hanging type outer surrounding member for elevator hoistway frame columns is proposed to achieve a more practical value purpose. Content of the Utility Model

[0005] The purpose of the utility model is to provide a hanging type outer surrounding member for elevator hoistway frame columns to solve the problems in the above background technique that firstly, most of the current outer surrounding members are fixed by bolts, and there will be traces of punching, bolts and welding on the outer wall after installation, which affects the appearance. Secondly, there is no buffer mechanism for buffering when being bumped.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A hanging type outer surrounding member for elevator hoistway frame columns, including an inner structure layer, a limiting step and an outer structure layer. Limiting steps are arranged at the edges of the outer walls on both sides of the inner structure layer. Reinforcing ribs are arranged in an array on the inner wall of the inner structure layer. The outer structure layer is arranged on the side of the inner structure layer away from the reinforcing ribs. The inner structure layer matches the outer structure layer. Fitting members are arranged in an array on the outer walls on both sides of the inner structure layer.

[0007] Further, the fitting member includes a hanging ring, a movable groove, a spring and an abutting block. A movable groove is arranged on the inner wall of one side of the hanging ring. Springs are arranged in an array on the inner wall of the movable groove. One end of the spring away from the inner wall of the movable groove is connected with the abutting block.

[0008] Furthermore, hooks are arranged on both inner walls of the outer structural layer through bolts. The hooks are matched with the fitting members. The bottoms of multiple groups of hooks are all hung in the corresponding hanging rings. One end of the abutting block away from the spring abuts against the outer wall of the hook.

[0009] Furthermore, a buffer mechanism is arranged at the bottom of the hook in an array. The buffer mechanism includes a fixed sleeve, a resilient column, a connecting frame, a support spring, a sliding groove and a damping block. One end of the fixed sleeve is embedded with the resilient column. The end of the resilient column embedded in the fixed sleeve is connected with the connecting frame. A support spring is arranged on the side of the connecting frame away from the resilient column in an array. One end of the support spring away from the connecting frame abuts against the inner wall of the fixed sleeve.

[0010] Furthermore, sliding grooves are arranged on both inner walls of the fixed sleeve. Both ends of the connecting frame are connected with damping blocks. The damping blocks are embedded in the sliding grooves. The material of the damping blocks is rubber. One end of the buffer mechanism away from the inner wall of the outer structural layer is connected with an abutting plate. The abutting plate abuts against the outer wall of the inner structural layer.

[0011] Furthermore, the cross-sections of the inner structural layer and the outer structural layer are both "L"-shaped. A smooth layer is arranged on the outer wall of the outer structural layer.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: A hanging type outer surrounding member of an elevator shaft column realizes the connection between the outer structural layer and the inner structural layer by hanging the hook in the hanging ring, so that there are no traces of any punching, bolts and welding on the surface of the outer structural layer. The buffer mechanism is adopted to play a buffering role, avoiding damage caused by the inability to buffer when the cavities between the outer structural layer and the inner structural layer collide. The specific content is as follows:

[0013] Hooks are arranged on both inner walls of the outer structural layer through bolts in an array. The hooks are matched with the fitting members. The bottoms of multiple groups of hooks are all hung in the corresponding hanging rings. The connection between the outer structural layer and the inner structural layer is realized by hanging the hook in the hanging ring, so that there are no traces of any punching, bolts and welding on the surface of the outer structural layer. One end of the abutting block away from the spring abuts against the outer wall of the hook. When the hook is hung into the hanging ring, one side of the abutting block is compressed and retracted into the movable groove. The resilience of the spring makes the outer wall of the abutting block abut against the hook, thereby increasing the friction between the fitting member and the hook and preventing the outer structural layer and the inner structural layer from separating easily. When the cavity of the outer structural layer is collided, the resilient column rebounds towards the fixed sleeve, driving the connecting frame to displace. The displacement of the connecting frame compresses the support spring. The support spring is compressed and contracted to play a shock absorption and buffering role. After shock absorption, the support spring drives the connecting frame to rebound. The damping blocks at both ends of the connecting frame generate a certain resistance by rubbing against the inner wall of the sliding groove in the fixed sleeve to suppress the oscillation when the support spring rebounds after shock absorption, thereby playing a buffering effect and avoiding damage to the cavity of the device when it is bumped.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1 - Figure 4 , the present utility model provides a technical solution: a hanging type externally surrounded member of an elevator hoistway column, including an inner structure layer 1, a limit step 2 and an outer structure layer 4. Limit steps 2 are provided at the edges of the outer walls on both sides of the inner structure layer 1. The limit steps 2 play a limiting role to facilitate the installation of the plates covering the sides of the elevator hoistway. Reinforcing ribs 3 are arranged in an array on the inner wall of the inner structure layer 1. The reinforcing ribs 3 play a role in strengthening the strength of the inner structure layer 1. The outer structure layer 4 is arranged on the side of the inner structure layer 1 away from the reinforcing ribs 3. The inner structure layer 1 and the outer structure layer 4 are matched. The outer structure layer 4 and the inner structure layer 1 cooperate to externally cover the edges of the elevator hoistway column. Fittings 5 are arranged in an array on the outer walls on both sides of the inner structure layer 1, playing a connecting role.

[0021] The fitting 5 includes a hanging ring 51, a movable groove 52, a spring 53 and an abutting block 54. An inner wall on one side of the hanging ring 51 is provided with the movable groove 52. The inner wall of the movable groove 52 is arranged with the spring 53. The spring 53 is compressed and contracted. One end of the spring 53 away from the inner wall of the movable groove 52 is connected with the abutting block 54. The abutting block 54 can be embedded into the movable groove 52.

[0022] On both inner walls of the outer structural layer 4, hooks 6 are arranged in sequence through bolts. The hooks 6 are matched with the fitting 5. The bottom ends of multiple groups of hooks 6 are all hung in the corresponding hanging ring 51. By hanging the hooks 6 in the hanging ring 51, the connection between the outer structural layer 4 and the inner structural layer 1 is realized, so that there are no traces of any drilling, bolts and welding on the surface of the outer structural layer 4. One end of the abutting block 54 away from the spring 53 abuts against the outer wall of the hook 6. When the hook 6 is hung into the hanging ring 51, one side of the abutting block 54 is compressed and retracted into the movable groove 52. Through the resilience of the spring 53, the outer wall of the abutting block 54 abuts against the hook 6, thereby increasing the friction between the fitting 5 and the hook 6 and preventing the outer structural layer 4 and the inner structural layer 1 from being easily separated.

[0023] A buffer mechanism 7 is arranged in sequence at the bottom of the hook 6. The buffer mechanism 7 plays a buffering role to prevent the outer structural layer 4 and the inner structural layer 1 from being damaged due to the inability to buffer when colliding in the cavity. The buffer mechanism 7 includes a fixed sleeve 71, a resilient column 72, a connecting frame 73, a support spring 74, a sliding groove 75 and a damping block 76. One end of the fixed sleeve 71 is embedded with the resilient column 72. The end of the resilient column 72 embedded into the fixed sleeve 71 is connected with the connecting frame 73. On one side of the connecting frame 73 away from the resilient column 72, the support spring 74 is arranged in sequence. One end of the support spring 74 away from the connecting frame 73 abuts against the inner wall of the fixed sleeve 71.

[0024] On both inner walls of the fixed sleeve 71, the sliding grooves 75 are provided. Both ends of the connecting frame 73 are connected with the damping blocks 76. The damping blocks 76 are embedded into the sliding grooves 75. The material of the damping blocks 76 is rubber. One end of the buffer mechanism 7 away from the inner wall of the outer structural layer 4 is connected with an abutting plate 8. The abutting plate 8 abuts against the outer wall of the inner structural layer 1. When the cavity of the outer structural layer 4 is collided, the resilient column 72 rebounds towards the fixed sleeve 71 side, driving the connecting frame 73 to displace. The connecting frame 73 displaces and compresses the support spring 74. The support spring 74 is compressed and contracted to play a shock absorption and buffering role. After shock absorption, the support spring 74 drives the connecting frame 73 to rebound. A certain resistance is generated by the friction between the damping blocks 76 at both ends of the connecting frame 73 and the inner wall of the sliding groove 75 in the fixed sleeve 71 to suppress the oscillation when the support spring 74 rebounds after shock absorption, thereby achieving a buffering effect and preventing the cavity of the device from being damaged when being knocked.

[0025] Both the cross-sections of the inner structural layer 1 and the outer structural layer 4 are in an "L" shape. A smooth layer 9 is provided on the outer wall of the outer structural layer 4. The smooth layer 9 plays a role in beautification.

[0026] Working principle: When using a hanging-type outer surrounding member of the elevator hoist column, the inner structural layer 1 is fixed to the edges of the corners of the elevator hoist column by punching and riveting for outer cladding. The reinforcing rib 3 plays a role in strengthening the strength of the inner structural layer 1. The connection between the outer structural layer 4 and the inner structural layer 1 is realized by hanging the hook 6 into the hanging ring 51, so that there are no traces of punching, bolts and welding on the surface of the outer structural layer 4. When the hook 6 is hung into the hanging ring 51, one side of the abutting block 54 is compressed and retracted into the moving groove 52, and the resilience of the spring 53 makes the outer wall of the abutting block 54 abut against the hook 6, thereby increasing the friction between the fitting 5 and the hook 6 to prevent the outer structural layer 4 and the inner structural layer 1 from being easily separated. When the cavity of the outer structural layer 4 is collided, the resilient column 72 rebounds towards the fixed sleeve 71, driving the displacement of the connecting frame 73. The displacement of the connecting frame 73 compresses the support spring 74, and the support spring 74 is compressed and contracted to play a shock absorption and buffering role. After shock absorption, the support spring 74 drives the connecting frame 73 to rebound. A certain resistance is generated by the friction between the damping blocks 76 at both ends of the connecting frame 73 and the inner wall of the sliding groove 75 in the fixed sleeve 71 to suppress the oscillation when the support spring 74 rebounds after shock absorption, thereby achieving a buffering effect and preventing the device from being damaged at the cavity when being bumped.
