Description

Technical Field

[0001] The invention belongs to the technical field of lifting devices, and in particular relates to a double-inclined and bidirectionally adjustable inclined ladder and a working method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the field of construction, elevators, as key equipment for vertical transportation, play an irreplaceable role in improving construction efficiency and reducing labor intensity. Existing conventional elevators are mostly vertical lifting structures, which have extremely poor applicability when facing construction with walls with different inclination angles. Due to the inability to flexibly adjust the angle of the car, construction workers often need to reinstall the elevator multiple times, which not only consumes a lot of time and manpower costs, but also seriously affects the construction progress. At the same time, this type of elevator also has major hidden dangers in terms of stability and safety during operation. Due to the lack of precise angle adjustment and fixing devices, the car is prone to shaking during the lifting process, causing the goods to scatter and even causing safety accidents.

[0004] From a structural perspective, the connection between the guide rail frame and the car of traditional elevators is relatively simple, generally using a simple slider connection. This makes the car prone to jamming during the lifting process, affecting operating efficiency. Moreover, the structural strength of some guide rail frames is insufficient to withstand the heavy loads in harsh construction environments, causing deformation or even collapse, posing a serious threat to the safety of construction workers. In terms of the drive system, the drive method used by some elevators is inefficient, not only with high energy consumption but also difficult to achieve precise control, unable to meet the requirements of modern construction for high-precision elevator operations.

[0034] The bottom end of the side of the car is connected to the bottom of the car main frame 3 by hinge, and an angle adjustment device is provided at the top of the car. The angle adjustment device is a screw jack 4 with a screw 13 arranged horizontally. One end of the screw 13 of the screw jack 4 is hinged to the car main frame 3 for adjusting the angle between the car and the car main frame 3; a limiting device is also provided between the car and the car main frame 3 for adjusting and fixing the angle between the car and the car main frame 3, so that the car can be adjusted in angle in multiple directions, improving the applicability of the inclined ladder on walls with different inclination angles. Through real-time angle adjustment, multiple inclined angle constructions can be realized in a single installation, improving the construction efficiency; an inclination angle sensor 14 is provided on the car 10, and the inclination angle sensor 14 can detect the inclination angle of the car 10 in real time and accurately. When it detects that the inclination angle of the car 10 does not meet the set requirements, the inclination angle sensor 14 will send a signal in time to control the operation of the screw jack 4 and automatically adjust the inclination angle of the car 10 to keep it always within a safe and appropriate range, greatly improving the intelligent level and safety of the inclined ladder.

[0035] Furthermore, there are two of the limiting devices, which are respectively arranged on both sides of the angle adjustment device at the top of the car, for limiting the rotation angle of the car within a certain range and fixing the rotation angle of the car at a specific angle.

[0036] Further, the limiting device includes a slide rail plate and a pull rod 7. A plurality of limiting holes 5 and a limiting groove 6 are horizontally arranged on the slide rail plate. The limiting holes 5 are arranged above the limiting groove 6. One end of the pull rod 7 is hinged to the main car frame 3, and the other end is provided with a fixing pin 8 and a movable pin hole. The fixing pin 8 is used to connect the pull rod 7 to the limiting groove 6, and the movable pin hole is connected to the limiting hole 5 through a movable pin, so as to realize the limitation between the pull rod 7 and the slide rail plate.

[0037] Further, a limiting stopper is arranged at the other end of the lead screw 13 of the screw jack 4 to limit the moving stroke of the lead screw 13.

[0038] Further, the main car frame 3 is composed of two vertical beams, an upper mounting plate and a lower mounting plate. The upper mounting plate and the lower mounting plate are arranged between the two vertical beams. A hinge bracket 9 is arranged on one side of the lower mounting plate close to the car. The hinge bracket 9 is triangular, and the hinge bracket 9 is hinged to the bottom of the car 10; the pull rod 7 is hinged to the upper mounting plate, and the lead screw 13 is also hinged to the upper mounting plate.

[0039] Further, a plurality of hinge holes 15 are arranged on the upper mounting plate for hinging with the main car groove steel frame 2.

The rotation positioning pin holes 12 are arranged according to a set track and are used to cooperate with the hinge holes 15 to adjust the rotation angle between the main car frame 3 and the main car groove steel frame 2;

[0040] A plurality of rotation positioning pin holes 12 are also arranged on the lower mounting plate. The rotation positioning pin holes 12 are arranged according to a set track and are used to cooperate with the hinge holes 15 to adjust the rotation angle between the main car frame 3 and the main car groove steel frame 2, so that there are multiple rotation centers between the main car frame 3 and the main car groove steel frame 2.

[0041] Further, the main car slot steel frame 2 is composed of two vertical channel steels, a first transverse support and a second transverse support. The ends of the two vertical channel steels are fixedly connected through the first transverse support to form a rectangular frame. A second transverse support is arranged in the middle of the two vertical channel steels. An articulated seat 11 is arranged on the second transverse support for connecting with the articulated hole 15. Generally, hot-rolled channel steels are selected for the vertical channel steels, which have high bending resistance. The ends of the two vertical channel steels are firmly fixedly connected through the first transverse support to form a stable rectangular frame structure. This frame structure can effectively disperse and bear the weight and external forces from the car 10 and other components, ensuring the stability of the structure. The articulated seat 11 on the second transverse support is used to adjust the angle between the main car frame 3 and the main car slot steel frame 2, and can cooperate with multiple articulated holes 15 on the mounting plate to make there be multiple rotation centers between the main car frame 3 and the main car slot steel frame 2.

[0043] Further, the guide rail frame 1 is a square truss structure and is connected with the main car slot steel frame 2 through a guide rail pair. Generally, a rolling guide rail pair is adopted for the guide rail pair. This guide rail pair has the advantages of small friction coefficient, high motion accuracy, long service life, etc., and can ensure the smooth and stable vertical sliding of the main car slot steel frame 2 on the guide rail frame 1, greatly reducing the jamming and wear during operation, and improving the overall operation efficiency and safety of the elevator.

[0044] Further, a rack is arranged on the main car slot steel frame 2, a driving motor is arranged on the guide rail frame 1, a driving gear is arranged on the driving motor, and the guide rail frame 1 and the main car slot steel frame 2 are driven through a gear rack.

[0045] Embodiment 2

[0046] This embodiment provides a working method for a double-inclined and two-way adjustable inclined ladder, which specifically includes the following steps:

[0047] Before starting the elevator, comprehensively check whether the connections of all components are firm, including the connections between the main car slot steel frame 2 and the guide rail frame 1, the main car frame 3 and the main car slot steel frame 2, and the car 10 and the main car frame 3; check whether the limit device and the angle adjustment device are normal; confirm that the inclination angle sensor 14 is in good working condition.

[0048] S1. Turn on the drive motor. The drive motor drives the drive gear to rotate. The drive gear meshes with the rack on the main car slot steel frame 2, causing the main car slot steel frame 2 to slide vertically along the guide rail frame 1, realizing the vertical lifting of the main car frame 3 and the car 10.

[0049] S2. According to the construction requirements, if it is necessary to adjust the angle between the main car frame 3 and the main car slot steel frame 2, loosen the pin positioning parts between the main car slot steel frame 2 and the main car frame 3. By changing the connection position of the upper mounting plate and the hinge hole 15 of the main car slot steel frame 2, and cooperating with the rotation of the positioning pin hole 12 for repositioning, adjust the rotation angle of the main car frame 3 relative to the main car slot steel frame 2, and then fix it with the pin positioning parts.

[0050] When adjusting the angle between the main car frame 3 and the main car slot steel frame 2, the inclination sensor 14 real-time monitors the inclination angle of the car 10. When the detected angle does not meet the set requirements, it sends a signal to control the operation of the screw elevator 4. The screw 13 of the screw elevator 4 expands and contracts to adjust the angle between the car 10 and the main car frame 3, keeping the inclination angle of the car 10 within a suitable range. When adjusted to the required angle, adjust the angle of the car 10 through the operation of the limit device. One end of the pull rod 7 of the limit device is hinged to the upper mounting plate of the main car frame 3, and the fixed pin 8 at the other end is connected to the limit groove 6 of the slide rail plate. The movable pin hole is connected to the limit holes 5 at different positions on the slide rail plate through the movable pin. By changing the connection position, the limitation and fixation of the rotation angle of the car 10 are realized.

[0051] S3. After the work is completed, first adjust the angle of the car 10 to the horizontal state through the cooperation of the screw elevator 4 and the limit device. Then restore the angle between the main car frame 3 and the main car slot steel frame 2 to the initial position and fix it again with the pin positioning parts. Finally, start the drive motor to make the main car slot steel frame 2 descend to the initial position at the bottom of the guide rail frame 1.

[0052] Although the specific implementation manners of the present invention are described above in conjunction with the drawings, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that based on the technical solutions of the present invention, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the present invention.
