Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and particularly to a construction elevator with a cable limiting structure. Background Technique

[0002] A construction elevator, also known as a construction hoist or a construction elevator, plays a key role in vertically transporting pedestrians or building materials and goods on a construction site. Its working principle is that an electric hoist drives the wire rope to unwind and wind up, thereby pulling the lifting box to move up and down to transport goods. Construction elevators are widely used in the construction of interior and exterior decoration of high-rise buildings, bridges, chimneys and other buildings.

[0003] When the elevator is in use, its cable is prone to winding around other components of the elevator during the lifting process, such as guide rails, rollers, etc., resulting in friction or collision between the cable and other components, and the cable is prone to wear or tear. Therefore, a construction elevator with a cable limiting structure is needed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a construction elevator with a cable limiting structure to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A construction elevator with a cable limiting structure, including a base, an elevator main body, a lifting box and a cable main body. The top of the base is provided with the elevator main body, and both ends of the top of the elevator main body are provided with electric hoists. Wire ropes are wound around the electric hoists, and the bottom ends of the wire ropes are both connected to the lifting box. The two sides of the elevator main body are evenly distributed with limiting hoops, and the cable main body passes through between the limiting hoops. Both ends of one side of the limiting hoop are rotatably connected through a rotating shaft, and both ends of the other side of the limiting hoop are fixedly connected through fasteners. Limiting members are arranged on both sides inside the limiting hoop, and one side of each limiting member is in contact with the outer wall of the cable main body. Grooves are arranged on both sides inside the limiting hoop, and pressure-receiving members are arranged in the grooves through return springs. One end of each pressure-receiving member is connected to the limiting member.

[0006] Preferably, a guardrail is arranged on the top of the elevator main body, and the guardrail is made of galvanized steel pipe.

[0007] Preferably, a frame body is arranged on the top of each lifting box, and the bottom end of the wire rope is connected to the frame body through a hook.

[0008] Preferably, a placement groove is arranged at the bottom end inside the lifting box through a weight sensor, and 4 groups of weight sensors are arranged.

[0009] Preferably, limiting grooves are formed on both sides inside the groove, and limiting blocks are arranged on both sides of one end of the pressure-receiving member.

[0010] Preferably, balls are evenly distributed on one side of the limiting member close to the cable main body, and the balls are all in contact with the surface of the cable main body.

[0011] Preferably, a second fixing block is fixed to the top end of the weight sensor, and a first fixing block is arranged above the second fixing block.

[0012] Preferably, steel balls are arranged between the first fixing block and the second fixing block, and the top ends of the first fixing blocks are fixedly connected to the bottom of the placement groove.

Specific embodiments

[0021] 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. Based on the embodiments in 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.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model: a construction elevator with a cable limiting structure, including a base 1, an elevator main body 2, a lifting box 6 and a cable main body 7. The elevator main body 2 is arranged on the top of the base 1, and electric hoists 4 are arranged at both ends of the top of the elevator main body 2. Steel wire ropes 5 are wound on the electric hoists 4, and the bottom ends of the steel wire ropes 5 are connected to the lifting box 6;

[0023] At the bottom end inside the lifting box 6, a placement groove 15 is arranged through a weight sensor 17, and 4 groups of weight sensors 17 are arranged;

[0024] Frame bodies 16 are arranged at the tops of the lifting boxes 6, and the bottom ends of the steel wire ropes 5 are connected to the frame bodies 16 through hooks;

[0025] Place the goods that need to be lifted and transported during the construction process in the placement groove 15 inside the lifting box 6. Then, the electric hoist 4 drives the steel wire rope 5 to wind up, and the lifting box 6 is lifted;

[0026] The weight sensor 17 inside the lifting box 6 senses the weight of the goods and transmits a signal to the controller inside the base 1 when it exceeds the set value, preventing unsafe phenomena caused by overweight;

[0027] The top end of the weight sensor 17 is fixed with a second fixing block 20, and first fixing blocks 19 are arranged above the second fixing blocks 20;

[0028] Steel balls 18 are arranged between the first fixing block 19 and the second fixing block 20, and the top ends of the first fixing blocks 19 are fixedly connected to the bottom of the placement groove 15;

[0029] When weighing, after the first fixed block 19 is stressed, it acts on the second fixed block 20 through the steel ball 18 and then transmits to the weight sensor 17. The contact ends of the first fixed block 19 and the second fixed block 20 with the steel ball 18 are both arc-shaped structures, so that after weighing, the steel ball 18 can automatically reset, making it difficult for the first fixed block 19 to deviate and improving the weighing accuracy.

[0030] On both sides of the lift main body 2, limiting hoops 8 are evenly distributed, and the cable main body 7 passes through between the limiting hoops 8. Both ends on one side of the limiting hoop 8 are rotatably connected through a rotating shaft, and both ends on the other side of the limiting hoop 8 are fixedly connected through fasteners 14. Limiting members 11 are arranged on both sides inside the limiting hoop 8, and one side of each limiting member 11 contacts the outer wall of the cable main body 7.

[0031] When the lift main body 2 is working, the cable main body 7 is limited by the limiting hoop 8 to prevent the cable main body 7 from shaking and winding with other components.

[0032] Grooves 9 are opened on both sides inside the limiting hoop 8, and pressure-receiving members 13 are arranged in the grooves 9 through return springs 10. One ends of the pressure-receiving members 13 are connected to the limiting members 11.

[0033] The limiting member 11 finally contacts the outer wall of the cable main body 7 under the action of the return spring 10, which is applicable to cable main bodies 7 of different thicknesses. Moreover, the elastic characteristic of the return spring 10 allows the limiting member 11 to have a margin when contacting the outer wall of the cable main body 7, which can both limit the cable main body 7 and is not easy to squeeze the cable main body 7.

[0034] Limiting grooves are opened on both sides inside the groove 9, and limiting blocks are arranged on both sides of one end of the pressure-receiving member 13 to limit the movement range of the return spring 10 and prevent deviation and distortion.

[0035] Ball bearings 12 are evenly distributed on the side of the limiting member 11 close to the cable main body 7, and the ball bearings 12 all contact the surface of the cable main body 7, changing the sliding contact to rolling contact, which is beneficial to reducing the friction between the cable main body 7 and the limiting member 11.

[0036] A protective fence 3 is arranged at the top of the lift main body 2, and the protective fence 3 is made of galvanized steel pipe, which is convenient for protecting during the overhaul and maintenance of the electric hoist 4.

[0037] The specific model specifications of the electric hoist 4 and the weight sensor 17 need to be determined by selection calculation according to the specification parameters of the device. The selection calculation method is the prior art, so it will not be elaborated in detail.

[0038] Working principle: When the embodiment of the present application is in use, the goods that need to be lifted and transported during the construction process are placed in the placement groove 15 in the lifting box 6. Then, the electric hoist 4 drives the wire rope 5 to wind up, lifting the lifting box 6. The weight sensor 17 in the lifting box 6 senses the weight of the goods and transmits a signal to the controller in the base 1 when the weight exceeds the set value, preventing unsafe phenomena caused by overweight. When weighing, the first fixing block 19 is stressed and acts on the second fixing block 20 through the steel ball 18 and then transmits to the weight sensor 17. The contact ends of the first fixing block 19 and the second fixing block 20 with the steel ball 18 are both arc-shaped structures, so that after weighing, the steel ball 18 can automatically reset, making it difficult for the first fixing block 19 to deviate and improving the weighing accuracy. When the elevator main body 2 is working, the cable main body 7 is limited by the limiting hoop 8 to prevent the cable main body 7 from shaking and winding with other components. The limiting member 11 finally contacts the outer wall of the cable main body 7 under the action of the return spring 10, which is applicable to cable main bodies 7 of different thicknesses. Moreover, the elastic characteristic of the return spring 10 allows the limiting member 11 to have a margin when contacting the outer wall of the cable main body 7, which can both limit the cable main body 7 and is not easy to squeeze the cable main body 7. A plurality of balls 12 are evenly distributed on one side of the limiting member 11, changing the sliding contact to rolling contact, which is beneficial to reducing the friction between the cable main body 7 and the limiting member 11.
