Description

Technical Field

[0001] The invention relates to the technical field of support frames, and in particular to a support frame for high-rise building construction. Background Art

[0002] With the rapid development of modern construction technology, high-rise building construction has become the norm in urban construction. In the process of high-rise building construction, the support frame is an important temporary structure, and its stability and safety are directly related to the smooth progress of the entire construction process and the quality of the building. However, although the existing high-rise building construction support frame has certain flexibility in height adjustment, there are still some problems that need to be solved in practical applications.

[0003] Specifically, the existing support frame is usually adjusted in height by telescopic rods or hydraulic lifting. Although this method can easily adjust the height of the support frame to meet different construction requirements, a common problem when the height of the support frame is increased is that the center of gravity of the support frame as a whole moves upward, while the supporting area of ​​the base remains unchanged. This design limitation causes the stability of the support frame to decrease significantly when the height increases.

[0004] As the height of the support frame increases, its overall center of gravity moves upward, making the support frame more likely to overturn or shake when subjected to external forces. Especially when the construction load is uneven, the stability problem of the support frame becomes more prominent, which not only affects the construction efficiency, but also poses certain safety hazards;

[0005] Especially for indoor support frames, due to their convenience and mobility requirements, they cannot improve stability by increasing the weight of the base like traditional construction frames, which leads to a particularly serious problem of decreased stability of such support frames as the height increases.

[0006] Therefore, a high-rise building construction support frame is needed to overcome the occurrence of the above-mentioned problems. Summary of the invention

[0007] In order to solve the above problems, an embodiment of the present invention provides a high-rise building construction support frame, which achieves the purpose of solving the problems raised in the background technology.

[0008] In order to achieve the above-mentioned purpose, the embodiment of the present invention specifically adopts the following technical scheme: a high-rise building construction support frame, including: a base, which is arranged on the ground for support; a platform, which is arranged above the base for carrying people or objects; a scissors frame, which is arranged between the base and the platform and is used to adjust the height of the platform; and a support assembly, which is arranged on the base, moves with the extension and retraction of the scissors frame, and cooperates with the base for auxiliary support.

[0009] As a further improvement of the above technical solution:

[0010] The base is provided with a driving assembly for driving the scissors frame to extend and retract;

[0011] The driving assembly includes a guide rail fixedly connected to the base, a screw rod rotatably arranged inside the guide rail, a slider threadedly connected to the outside of the screw rod and sliding inside the guide rail, and a motor installed on one side of the base for driving the screw rod to rotate.

[0012] One side of the bottom of the scissors frame is hinged to the base, and the other side of the bottom of the scissors frame is hinged to the slider 1;

[0013] A second slide block is slidably arranged at the bottom of the platform, one side of the top of the scissors frame is hinged to the platform, and the other side of the top of the scissors frame is hinged to the second slide block.

[0014] Universal wheels are arranged on one side of the base and one side of the guide rail, and supporting wheels 2 are arranged on the sliding block 1.

[0015] The support assembly includes a support rod 1 hinged to one side of the base and a support rod 2 hinged to a slider 1; one end of the support rod 1 is hinged to one end of the support rod 2, and a support wheel 1 is provided at the hinge between the support rod 1 and the support rod 2.

[0016] The platform is provided with a fence;

[0017] The enclosure includes a baffle plate 1 hingedly arranged on the side of the platform in the length direction, and a baffle plate 2 hingedly arranged on one side of the platform in the width direction; the baffle plate 1 and the baffle plate 2 are fixedly connected by a snap-fit ​​assembly.

[0018] The baffle plate 1 is provided with a slide groove, a pulley is slidably provided inside the slide groove, one side of the pulley is fixedly connected to a baffle rod, the other side of the pulley is fixedly connected to a connecting rope, and one end of the connecting rope is fixedly connected to the slider 2.

[0019] The buckle assembly comprises a base fixedly connected to the second baffle, a latch elastically slidably arranged inside the base through a spring, and a clamping block fixedly connected to the first baffle and used in conjunction with the latch.

[0020] The beneficial effects of the embodiments of the present invention are:

[0021] In actual use, the base is set on the ground for support, and a person or object is placed on the platform. The height of the platform is adjusted by extending and retracting the scissor frame. At the same time, the scissor frame drives the support assembly to move when extending and retracting, thereby providing auxiliary support. That is, when the height of the platform is increased, the support assembly moves and extends, thereby increasing the support area at the bottom, thereby improving stability, and avoiding the problem of poor stability caused by the increase in the center of gravity after the height is increased;

[0022] When the support frame is in use, the pressure is mainly concentrated on the bottom of the scissors frame. One side of the bottom of the scissors frame is connected to a base, which can provide support to it, and the other side of the scissors frame is connected to the slider 1. Since the length of the screw rod is long, that is, its span is large, the screw rod is prone to bending and deformation. After the screw rod is bent and deformed, it is easy to cause the sliding of the slider 1 to be blocked, and the bent and deformed screw rod makes the support frame tilted, making it difficult to provide good support. Therefore, the slider 1 is supported by the support wheel 2 to prevent the screw rod from bending and deformation due to force;

[0023] In actual use, when the height of the platform is adjusted upward, the scissors frame is extended, that is, the slider 1 moves closer to the base, thereby driving the support rod 2 to move, and a triangle is formed between the support rod 1, the support rod 2 and the screw rod. When the support rod 2 moves closer to the base, it drives the hinge point of the support rod 1 and the support rod 2 to expand outward (move away from the screw rod), that is, drives the support wheel 1 to expand outward, thereby increasing the area between the support wheel 1 and the base, that is, increasing the support area, thereby achieving the purpose of increasing the support area between the support assembly and the base as the height of the platform is adjusted upward (extending the scissors frame), that is, achieving the purpose of the support assembly cooperating with the base for auxiliary support;

[0024] The enclosure includes a baffle plate 1 hingedly arranged on the side of the platform in the length direction, and a baffle plate 2 hingedly arranged on one side of the platform in the width direction; the baffle plate 1 and the baffle plate 2 are fixedly connected by a buckle assembly; in actual use, when the support frame is used for people to stand, the baffle plate 1 and the baffle plate 2 are erected on the top of the platform through the buckle assembly, so as to enclose the platform; when the support frame is used for lifting and supporting materials or supporting certain building structures, the baffle plate 1 and the baffle plate 2 are separated by the buckle assembly, so that the baffle plate 1 and the baffle plate 2 are folded on the side of the platform, so that the top of the platform is flat, which is convenient for the support frame to be used for lifting and supporting materials or supporting certain building structures; that is, by changing the position of the enclosure, the support frame can be used for people or objects, thereby improving the functionality of the support frame;

[0025] In actual use, when the height of the platform is increased, the scissors frame extends, so that the support of the scissors frame to the platform changes from the original support on both sides of the platform to support on one side of the platform and the middle of the platform, which causes the part of the platform that is not directly above the scissors frame (part one) to become suspended. When a person stands on part one of the platform, it causes the scissors frame to be twisted and sheared, affecting the support stability of the scissors frame. In order to avoid this problem, the slider 2 and the stopper rod are connected by a connecting rope, so that the stopper rod can move with the movement of the slider 2, that is, the enclosure range on the platform is located directly above the scissors frame, that is, the standing range of the person is located directly above the scissors frame, so as to avoid the person standing on the platform temporarily affecting the support stability of the scissors frame;

[0026] When the scissors frame of the present application is extended, the height of the platform is adjusted, and at the same time, the support assembly is driven to extend the support (increasing the support range and improving stability), and the baffle rod is driven to move and limit the position (limiting the standing range above the platform so that the standing range is directly above the scissors frame); and in the present application, the extension of the scissors frame, the height adjustment of the platform, the extension of the support assembly, and the movement and limitation of the baffle rod can all be achieved through a single driving assembly, with a simple structure, while ensuring the synchronization of the extension of the scissors frame, the height adjustment of the platform, the extension of the support assembly, and the movement and limitation of the baffle rod, which is convenient for practical use.

DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0033] See also Figures 1 to 4 The embodiment of the present invention discloses a high-rise building construction support frame, comprising:

[0034] A base 1 is arranged on the ground for support;

[0035] A platform 2 is arranged above the base 1 and is used to carry people or objects;

[0036] a scissor frame 3, arranged between the base 1 and the platform 2, and used for adjusting the height of the platform 2; and

[0037] The support assembly 4 is arranged on the base 1, moves along with the extension and retraction of the scissor frame 3, and cooperates with the base 1 for auxiliary support;

[0038] In actual use, the base 1 is set on the ground for support, and a person or object is located on the platform 2. The height of the platform 2 is adjusted by extending and retracting the scissors frame 3. At the same time, the scissors frame 3 drives the support component 4 to move during extension and retraction, thereby providing auxiliary support. That is, when the height of the platform 2 increases, the support component 4 moves and extends, thereby increasing the support area at the bottom, thereby improving stability, and avoiding the problem of poor stability caused by the increase in the center of gravity after the height increases.

[0039] As a further illustration of this application:

[0040] The base 1 is provided with a driving assembly 5 for driving the scissor frame 3 to extend and retract;

[0041] The driving assembly 5 includes a guide rail 51 fixedly connected to the base 1, a screw rod 52 rotatably arranged inside the guide rail 51, a slider 53 threadedly connected to the outside of the screw rod 52 and sliding inside the guide rail 51, and a motor 54 installed on one side of the base 1 for driving the screw rod 52 to rotate;

[0042] In actual use, after the motor 54 is started, it drives the screw rod 52 to rotate, thereby driving the slider 1 53 to move, and the scissors frame 3 can be driven to extend and retract.

[0043] As a further illustration of this application:

[0044] One side of the bottom of the scissors frame 3 is hinged to the base 1, and the other side of the bottom of the scissors frame 3 is hinged to the slider 1 53; when the slider 1 53 moves, one side of the scissors frame 3 is driven to move, thereby driving the scissors frame 3 to extend and retract;

[0045] A slider 2 12 is slidably provided at the bottom of the platform 2, one side of the top of the scissors frame 3 is hinged to the platform 2, and the other side of the top of the scissors frame 3 is hinged to the slider 2 12. When one side of the bottom of the scissors frame 3 moves, one side of the top of the scissors frame 3 is driven to move, which can drive the slider 2 12 to move.

[0046] As a further illustration of this application:

[0047] Universal wheels 13 are provided on one side of the base 1 and one side of the guide rail 51, and support wheels 14 are provided on the slider 1 53. The base 1 and the guide rail 51 are supported by the universal wheels 13. At the same time, the universal wheels 13 are provided to facilitate the movement of the support frame as a whole. The universal wheels 13 are provided with brakes. When performing the support operation, the brakes on the universal wheels 13 are turned on to avoid movement during the support operation. When the support frame needs to be moved, the brakes on the universal wheels 13 are turned off, and the support frame can be moved normally at this time.

[0048] When the support frame is in use, the pressure is mainly concentrated on the bottom of the scissors frame 3. One side of the bottom of the scissors frame 3 is connected to the base 1, which can provide support to it, and the other side of the scissors frame 3 is connected to the slider 1. Since the length of the screw rod 52 is long, that is, its span is large, the screw rod 52 is prone to bending and deformation. After the screw rod 52 is bent and deformed, the sliding of the slider 1 53 is easily obstructed, and the bent and deformed screw rod 52 makes the support frame tilted, making it difficult to provide good support. Therefore, the slider 1 53 is supported by the support wheel 2 14 to prevent the screw rod 52 from bending and deformation due to force.

[0049] As a further illustration of this application:

[0050] The support assembly 4 includes a support rod 1 41 hinged to one side of the base 1, and a support rod 2 42 hinged to a slider 1 53; one end of the support rod 1 41 is hinged to one end of the support rod 2 42, and a support wheel 1 43 is provided at the hinge of the support rod 1 41 and the support rod 2 42;

[0051] In actual use, when the height of the platform 2 is adjusted upward, the scissors frame 3 is extended, that is, the slider 1 53 moves closer to the base 1, thereby driving the support rod 2 42 to move, and a triangle is formed between the support rod 1 41, the support rod 2 42 and the screw rod 52. When the support rod 2 42 moves closer to the base 1, the hinge point of the support rod 1 41 and the support rod 2 42 is driven to expand outward (move away from the screw rod 52), that is, the support wheel 1 43 is driven to expand outward, thereby increasing the area between the support wheel 1 43 and the base 1, that is, increasing the support area, thereby achieving the purpose of increasing the support area between the support assembly 4 and the base 1 as the height of the platform 2 is adjusted (the scissors frame 3 is extended), that is, achieving the purpose of the support assembly 4 cooperating with the base 1 for auxiliary support;

[0052] At the same time, the support assembly 4 and the platform 2 in the present application share a set of driving assemblies 5. Compared with using two sets of driving assemblies to drive the support assembly 4 and the platform 2 respectively, the present application avoids the problem that the height of the platform 2 is increased while the support assembly 4 is not expanded outward, and ensures that while the height of the platform 2 is increased, the support assembly 4 is expanded outward for auxiliary support.

[0053] As a further illustration of this application:

[0054] A fence 6 is provided on the platform 2; the fence 6 is used to enclose the platform 2, thereby protecting the personnel standing on the platform 2;

[0055] The enclosure 6 includes a baffle 1 61 hingedly arranged on the side of the length direction of the platform 2, and a baffle 2 62 hingedly arranged on one side of the width direction of the platform 2; the baffle 1 61 and the baffle 2 62 are fixedly connected by a snap assembly 7; in actual use, when the support frame is used for people to stand, the baffle 1 61 and the baffle 2 62 are erected on the top of the platform 2 by the snap assembly 7, so as to enclose the platform 2; when the support frame is used for lifting and supporting materials or supporting certain building structures, the baffle 1 61 and the baffle 2 62 are separated by the snap assembly 7, so that the baffle 1 61 and the baffle 2 62 are folded on the side of the platform 2, so that the top of the platform 2 is flat, which is convenient for the support frame to be used for lifting and supporting materials or supporting certain building structures; that is, by changing the position of the enclosure 6, the support frame can be used for people or objects, thereby improving the functionality of the support frame.

[0056] As a further illustration of this application:

[0057] A slide groove 8 is provided on the baffle plate 1 61, and a pulley 9 is slidably provided inside the slide groove 8. A blocking rod 10 is fixedly connected to one side of the pulley 9, and a connecting rope 11 is fixedly connected to the other side of the pulley 9. One end of the connecting rope 11 is fixedly connected to the slider 2 12. The blocking rods 10 provided on the two baffle plates 1 61 are connected to form a block, so that a complete enclosure is formed by the baffle plate 1 61, the baffle plate 2 62 and the blocking rod 10; a bearing is provided inside the pulley 9 for rotation, the blocking rod 10 is fixed on one side of the bearing, and the connecting rope 11 is fixed on the other side of the bearing; the connecting rope 11 is relatively soft, which meets the requirement that the slider 2 12 pulls and drives the blocking rod 10 to move, and at the same time, the connecting rope 11 will not affect the folding of the baffle plate 1 61 on the side of the platform 2;

[0058] When the scissor frame 3 is extended or retracted, the slider 12 moves, thereby driving the pulley 9 to move through the connecting rope 11, and then driving the barrier rod 10 to move, so that the barrier rod 10 is always directly above the slider 12, that is, the enclosure range on the platform 2 is directly above the scissor frame 3, that is, the standing range of the personnel is directly above the scissor frame 3;

[0059] In actual use, when the height of the platform 2 is increased, the scissors frame 3 extends, so that the support of the scissors frame 3 to the platform 2 changes from the original support on both sides of the platform 2 to support on one side of the platform 2 and the middle of the platform 2. This causes the part of the platform 2 that is not directly above the scissors frame 3 (part one) to become suspended. When a person stands on part one of the platform 2, the scissors frame 3 is twisted and sheared, affecting the support stability of the scissors frame 3. In order to avoid this problem, the slider 12 and the baffle 10 are connected by a connecting rope 11, so that the baffle 10 can move with the movement of the slider 12, so that the enclosure range on the platform 2 is located directly above the scissors frame 3, that is, the standing range of the person is located directly above the scissors frame 3, so as to avoid the person standing on the part of the platform 2 temporarily affecting the support stability of the scissors frame 3.

[0060] As a further illustration of this application:

[0061] The buckle assembly 7 includes a base 71 fixedly connected to the baffle plate 2 62, a latch 73 elastically slidably arranged inside the base 71 by a spring 72, and a clamping block 74 fixedly connected to the baffle plate 1 61 and used in conjunction with the latch 73; when the baffle plate 1 61 and the baffle plate 2 62 are fixed, the baffle plate 2 62 is first rotated to make the baffle plate 2 62 stand upright on the platform 2, and then the baffle plate 1 61 is rotated to make the baffle plate 1 61 stand upright. When the baffle plate 1 61 moves, the baffle plate 1 6 The block 74 on 1 is engaged with the latch pin 73, so as to realize the splicing and fixing of the baffle plate 1 61 and the baffle plate 2 62. That is, when the baffle plate 1 61 and the baffle plate 2 62 are spliced ​​and fixed, it is only necessary to rotate the baffle plate 2 62 first and then rotate the baffle plate 1 61, which is convenient for operation. When it is necessary to separate the baffle plate 1 61 and the baffle plate 2 62, the latch pin 73 is pulled to separate the latch pin 73 and the block 74. At this time, the baffle plate 1 61 can be rotated to separate the baffle plate 1 61 and the baffle plate 2 62.

[0062] As a further illustration of this application:

[0063] When the scissors frame 3 of the present application is extended, the height adjustment of the platform 2 is achieved, and at the same time, the support component 4 is driven to extend the support (increasing the support range and improving stability), and the baffle 10 is driven to move and limit the position (limiting the standing range above the platform 2 so that the standing range is directly above the scissors frame 3); and in the present application, the extension of the scissors frame 3, the height adjustment of the platform 2, the extension of the support component 4, and the movement and limitation of the baffle 10 can all be achieved through a single driving component 5, which has a simple structure and ensures the synchronization of the extension of the scissors frame 3, the height adjustment of the platform 2, the extension of the support component 4, and the movement and limitation of the baffle 10, which is convenient for practical use.
