Description

Technical Field

[0001] The utility model relates to the technical field of housing engineering construction, in particular to a lifting construction platform for housing engineering construction. Background Art

[0002] Housing engineering is a general term for the survey, planning, design, construction and equipment commissioning of housing construction. The ultimate goal is to provide a suitable place for human production and life. With the update of materials and the advancement of technology, the water supply, drainage, heating, ventilation, air conditioning, lighting, fire protection, sound insulation, dust prevention and other equipment of buildings have been continuously improved, making the production and living environment of human beings more and more comfortable.

[0003] During housing construction work, it is often necessary to use lifting equipment to lift construction workers to a suitable height so that they can carry out construction work on building components that are at a higher position during the housing construction process.

[0004] However, the existing lifting construction platforms for housing engineering construction generally only have simple lifting functions and enclosure protection functions. When personnel are on the lifting platform, it is difficult to achieve enhanced locking of the protective door while ensuring ease of operation, which in turn affects the safety of personnel during construction operations and poses certain safety hazards. For this reason, we propose a lifting construction platform for housing engineering construction. Utility Model Content

The front and rear inner walls of the sliding seat are rotatably connected to the inclined support rod through a pin shaft. The horizontal sliding grooves symmetrically arranged at the front and rear of the bottom of the lifting platform are slidably connected to the connecting seats symmetrically on the left and right sides. The upper ends of the inclined support rods are rotatably connected to the connecting seats diagonally distributed on the same side of the horizontal axis through a pin shaft. It can meet the needs of construction operations at different heights, has a wider range of applications, and can achieve enhanced locking of protective doors to ensure the safety of personnel performing construction operations.

[0009] Furthermore, a control switch is provided on the front side of the base, and the input end of the control switch is electrically connected to an external power supply, so that the operating state of the motor can be freely adjusted.

[0010] Furthermore, the lifting mechanism also includes a connecting rod, a bidirectional screw rod and a motor. The connecting rod is rotatably connected between the corresponding rotating holes opened at the centers of the four diagonal support rods. The bidirectional screw rod is rotatably connected to the inside of the base through a bearing. The left and right ends of the bidirectional screw rod are respectively threadedly connected to the middle screw holes of the slide seat on the same side. The motor output shaft arranged on the right side of the base is fixedly connected to the bidirectional screw rod. The input end of the motor is electrically connected to the output end of the control switch, which can drive the left and right slide seats to approach each other.

[0011] Furthermore, sleeve telescopic joints are provided in the mounting openings at the four corners of the base, and the upper ends of the telescopic ends of the sleeve telescopic joints are fixedly connected to the lifting platform, which can provide further guiding and supporting effects for the lifting platform.

[0012] Furthermore, a storage cavity is provided in the middle of the front side surface of the protective door, and a limiting rod is slidably connected to the inside of the storage cavity. A limiting hole is provided in the middle of the front inner wall of the left opening of the lifting platform. The limiting rod and the limiting hole are movably connected to achieve preliminary limiting of the protective door.

[0013] Furthermore, the front end surface of the limiting rod is tilted from back to front toward the direction close to the central axis of the limiting rod, which can ensure that subsequent work can be carried out normally.

[0014] Furthermore, a spring is provided inside the storage cavity, the front end of the spring is fixedly connected to the step plate in the middle of the limiting rod, and the spring is sleeved on the outside of the limiting rod to cause the limiting rod to automatically reset.

[0015] Furthermore, a rotating chamber is provided at the inner center of the protective door, the rotating chamber is connected with the storage chamber, a handle is rotatably connected at the inner center of the rotating chamber, a turntable is provided on the front end fixed sleeve of the handle, the turntable is located inside the rotating chamber, an arc-shaped sliding opening is provided on the rear side of the protective door, the rear end of the handle is located inside the arc-shaped sliding opening, the center of the arc-shaped sliding opening coincides with the center of the rotating chamber, and an avoidance opening is provided in the middle of the upper end of the outer arc surface of the rotating chamber, which can achieve enhanced locking of the protective door by limiting the retraction of the limit rod.

[0016] Furthermore, universal wheels are symmetrically arranged at the four corners of the bottom surface of the base to facilitate movement.

[0017] Compared with the prior art, the beneficial effects of the utility model are: the lifting construction platform for housing engineering construction has the following advantages:

[0018] 1. After the base is moved to the specified position by the universal wheel, the personnel manually rotate the turntable through the handle until the avoidance opening is aligned with the limit rod. At this time, the personnel pulls the protective door outward to make the front end conical surface of the limit rod contact the edge of the limit hole. As the personnel manually applies force, the rear end of the limit rod will overcome the elastic force of the spring and automatically insert into the inside of the avoidance opening. At the same time, the front end of the limit rod will be pulled out from the inside of the limit hole, thereby releasing the lock on the protective door. The operation is simple and practical.

[0019] 2. After the personnel enter the interior of the lifting platform and close the protective door, the limit rod will automatically be inserted into the limit hole due to the elastic potential energy of the spring to achieve the initial locking and limiting of the protective door. After that, the personnel rotate the turntable through the handle to cause the avoidance opening and the limit rod to be misaligned. By limiting the retraction of the limit rod, the protective door is strengthened and locked, ensuring the safety of personnel during construction operations.

[0020] 3. Through the regulation of the control switch, the operation of the motor drives the bidirectional screw to rotate. Affected by the threaded connection between the bidirectional screw and the slide, the two slides can be moved closer to each other. At this time, the diagonal support rod will gradually rotate toward the vertical state due to the support limit provided by the connecting rod, and the corresponding horizontal connecting seats will move closer to each other. Because the length of the diagonal support rod is certain, the height of the lifting platform can be changed to meet the construction operations at different heights. The scope of application is wider, and the sleeve expansion joint can provide further guiding support for the lifting platform as mentioned above, thereby ensuring the stability of the lifting platform.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 , this embodiment provides a technical solution: a lifting construction platform for housing engineering construction, including a base 1, a lifting platform 2 and a lifting mechanism 3;

[0029] A protective door 4 is hingedly connected to the left opening of the lifting platform 2 through a hinge;

[0030] The lifting mechanism 3 includes a slide seat 31, an oblique support rod 32 and a connecting seat 33. The slide seat 31 is symmetrically slidably connected to the inside of the base 1. The front and rear inner walls of the slide seat 31 are rotatably connected to the oblique support rod 32 through a pin shaft. The horizontal slide grooves symmetrically arranged on the front and rear sides of the bottom of the lifting platform 2 are slidably connected to the left and right symmetrical connecting seats 33. The upper ends of the oblique support rods 32 are rotatably connected to the connecting seats 33 diagonally distributed on the same side of the horizontal through a pin shaft. The lifting mechanism 3 also includes a connecting rod 34, a two-way screw rod 35 and a motor 36. The connecting rod 34 is rotatably connected between the corresponding rotating holes opened at the centers of the four oblique support rods 32. The two-way screw rod 35 is rotatably connected to the inside of the base 1 through a bearing. The left and right ends of the two-way screw rod 35 are respectively connected to the slide seat 31 on the same side. The middle screw hole is threadedly connected, and the output shaft of the motor 36 arranged on the right side of the base 1 is fixedly connected to the bidirectional screw rod 35. The input end of the motor 36 is electrically connected to the output end of the control switch 5. Through the regulation of the control switch 5, the operation of the motor 36 drives the bidirectional screw rod 35 to rotate. Affected by the threaded connection relationship between the bidirectional screw rod 35 and the slide seat 31, the two slide seats 31 can be moved closer to each other. At this time, the diagonal support rod 32 will gradually rotate toward the vertical state due to the support limit provided by the connecting rod 34, and the corresponding connecting seat 33 will move closer to each other. Because the length of the diagonal support rod 32 is fixed, the height of the lifting platform 2 can be changed, so as to meet the construction operations at different heights, and the scope of application is wider.

[0031] A control switch 5 is provided on the front side of the base 1 , and an input end of the control switch 5 is electrically connected to an external power source.

[0032] Sleeve expansion joints 6 are provided in the mounting openings at the four corners of the base 1. The upper ends of the expansion ends of the sleeve expansion joints 6 are fixedly connected to the lifting platform 2, which can provide further guiding and supporting function for the lifting platform 2 as mentioned above, thereby ensuring the stability of the lifting platform 2.

[0033] A storage chamber 7 is provided in the middle of the front side of the protective door 4, and the internal sliding connection of the storage chamber 7 is connected to a limiting rod 8. A limiting hole 9 is provided in the middle of the front inner wall of the left opening of the lifting platform 2, and the limiting rod 8 is movably plugged into the limiting hole 9. The front end surface of the limiting rod 8 is inclined from back to front in the direction close to the central axis of the limiting rod 8. A spring 10 is provided inside the storage chamber 7, and the front end of the spring 10 is fixedly connected to the step plate in the middle of the limiting rod 8. The spring 10 is sleeved on the outside of the limiting rod 8. A rotating chamber 11 is provided at the inner center of the protective door 4, and the rotating chamber 11 is connected to the storage chamber 7. A handle 13 is rotatably connected at the inner center of the rotating chamber 11. The front end of the handle 13 is fixedly sleeved with a turntable 12, and the turntable 12 is located inside the rotating chamber 11. An arc-shaped sliding port 14 is provided on the rear side of the protective door 4, and the rear end of the handle 13 is located inside the arc-shaped sliding port 14. The center of the arc-shaped sliding port 14 coincides with the center of the rotating chamber 11. After that, the personnel rotates the turntable 12 by the handle 13, so that the avoidance opening 15 and the limit rod 8 are misaligned, and the protective door 4 is strengthened and locked by limiting the retraction of the limit rod 8, thereby ensuring the safety of the personnel when performing construction operations.

[0034] Universal wheels 16 are symmetrically arranged at the four corners of the bottom surface of the base 1 , and the base 1 can be moved to any position through the universal wheels 16 .

[0035] The working principle of the lifting construction platform for housing engineering provided by the utility model is as follows: after the base 1 is moved to the specified position by the universal wheel 16, the personnel manually rotate the turntable 12 through the handle 13 until the avoidance opening 15 is aligned with the limit rod 8. At this time, the personnel pulls the protective door 4 outward to make the front end conical surface of the limit rod 8 contact the edge of the limit hole 9. As the personnel manually applies force, the rear end of the limit rod 8 will overcome the elastic force of the spring 10 and automatically insert into the inside of the avoidance opening 15. At the same time, the front end of the limit rod 8 will be pulled out from the inside of the limit hole 9, thereby releasing the lock on the protective door 4. After the personnel enters the interior of the lifting platform 2 and closes the protective door 4, the limit rod 8 will automatically insert into the inside of the limit hole 9 due to the elastic potential energy of the spring 10 to achieve the preliminary locking and limiting of the protective door 4. After that, the personnel rotate the turntable 12 through the handle 13 , so that the avoidance opening 15 and the limit rod 8 are misaligned, and the protective door 4 is strengthened and locked by limiting the retraction of the limit rod 8, thereby ensuring the safety of personnel when performing construction operations. By controlling the control switch 5, the motor 36 drives the two-way screw rod 35 to rotate. Affected by the threaded connection relationship between the two-way screw rod 35 and the slide seat 31, the two slide seats 31 can be moved closer to each other. At this time, the diagonal support rod 32 will gradually rotate toward the vertical state due to the support limit provided by the connecting rod 34, and the corresponding connecting seat 33 will move closer to each other. Because the length of the diagonal support rod 32 is certain, the height of the lifting platform 2 can be changed, so as to meet the construction operations at different heights, and the scope of application is wider. The sleeve telescopic joint 6 can provide further guiding and supporting function for the lifting platform 2 as mentioned above, thereby ensuring the stability of the lifting platform 2.

[0036] It is worth noting that the motor 36 disclosed in the above embodiment is a SM3L-042A1BDV servo motor, and the control switch 5 is provided with a switch button corresponding to the motor 36 for controlling its switching operation.
