Description

Technical Field

[0001] The utility model relates to the technical field of construction elevators, in particular to a building construction elevator. Background Art

[0002] Construction elevators are usually called construction hoists, but the definition of construction hoists is broader. Construction platforms also belong to the construction elevator series. A simple construction elevator is composed of a car, a drive mechanism, a standard section, a wall attachment, a chassis, a fence, an electrical system and other parts. It is a manned and cargo-carrying construction machinery frequently used in construction. Due to its unique box structure, it is both comfortable and safe to ride. Construction elevators are usually used in conjunction with tower cranes on construction sites. The general load capacity is 0.3-3.6 tons, and the operating speed ranges from 1-96M / min. However, in actual use, similar construction elevators still have many defects. For example, when existing construction elevators are loading and unloading goods, it is inconvenient to lift the goods out when the goods are too heavy, and the space inside the elevator is small, making it inconvenient for workers to enter and carry them. Summary of the invention

[0003] The purpose of the utility model is to provide a construction elevator to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a construction elevator, comprising an elevator, wherein two groups of fixed blocks are fixedly installed at the lower end of the interior of the elevator, sliding grooves are provided on the inner sides of the two groups of fixed blocks, guide rails are fixedly installed inside the sliding grooves, and the outer walls of the guide rails are slidably connected to support plates.

[0005] When using the construction elevator, the motor is started to rotate forward. When the motor rotates, it can drive the second gear to rotate. The second gear is meshed with the first gear to make the threaded rod rotate. When the threaded rod rotates, it can push the support plate to move along the direction of the guide rail. When it moves to the outer end of the elevator, the goods are put on, and then the motor is controlled to reverse, and the support plate and the goods are pulled into the elevator. When unloading is required, this operation can be repeated. There is no need for workers to enter the elevator to transport, which is convenient for operation. When the support plate is moving, the roller at the lower end of the support plate will also rotate with the support plate, reducing the force required to move the support plate, which can reduce the power of the motor and prevent the support plate from being unable to move when the motor power is insufficient.

[0006] As a preferred technical solution of the utility model, moving blocks are fixedly installed on both sides of one end of the support plate, and a guide rail groove is opened at one end of the moving block, and the guide rail groove cooperates with the guide rail.

[0007] As a preferred technical solution of the utility model, a baffle is fixedly installed on one side of the upper end of the support plate, fixed plates are fixedly installed on both sides of the lower end of the support plate, and rollers are fixedly installed in the middle of the two groups of fixed plates; by providing the baffle, when placing goods on the support plate, it can prevent the goods from exceeding the area of ​​the support plate, and when retracting inward, the goods will not collide with the elevator.

[0008] As a preferred technical solution of the utility model, a threaded hole is opened at the center of one end of the support plate, a threaded rod is rotatably fitted on the inner wall of the threaded hole, and a first gear is fixedly installed on one end of the threaded rod.

[0009] As a preferred technical solution of the utility model, an elevator hole is opened at the lower end of the interior of the elevator, and an elevator groove is opened at the bottom end of the elevator near the edge, and the elevator groove is communicated with the elevator hole.

[0010] As a preferred technical solution of the utility model, the outer wall of the threaded rod cooperates with the elevator hole, the first gear is rotatably installed inside the elevator slot, and support seats are arranged around the lower end of the elevator; by providing the support seats, the elevator can be prevented from pressing on the motor when descending to the ground.

[0011] As a preferred technical solution of the utility model, a motor is fixedly installed on one side of the elevator slot at the lower end of the elevator, and a second gear is fixedly installed on the output end of the motor, and the second gear is meshed with the first gear; by providing the first gear, the first gear can transmit the torque of the motor to the threaded rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When using the construction elevator, start the motor to rotate forward. When the motor rotates, it can drive the second gear to rotate. The second gear is meshed with the first gear to make the threaded rod rotate. When the threaded rod rotates, it can push the support plate to move along the direction of the guide rail. When it moves to the outer end of the elevator, put the goods on it, and then control the motor to reverse, and pull the support plate and the goods into the elevator. When unloading is required, just repeat this operation. There is no need for workers to enter the elevator to transport, which is convenient for operation. When the support plate is moving, the roller at the lower end of the support plate will also rotate with the support plate, reducing the force required to move the support plate, which can reduce the power of the motor and prevent the support plate from being unable to move when the motor power is insufficient.

[0014] 2. By providing a roller, when the support plate is moving, the roller at the lower end of the support plate will also rotate with the support plate, reducing the force required to move the support plate, reducing the power of the motor, and preventing the support plate from being unable to move when the motor power is insufficient.
