Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an adjustable support frame. Background Art

[0002] The construction adjustment support frame is an important equipment used to support, fix or adjust the position of the structure during the construction process.

[0003] The existing Chinese patent (publication number: CN216239603U) proposes an adjustable support frame for construction engineering construction, including two positioning plates, the upper ends of the two positioning plates are fixedly connected to the support rods, and a movable sleeve is sleeved on the support rods. The movable sleeve and the support rods are slidably connected, and an adjustment plate is fixedly connected between the two movable sleeves. Two fixed plates are fixedly sleeved on the side walls of the two support rods, and a rack is fixedly connected between the two fixed plates located on the same support rod. A channel is opened at the position of the adjustment plate corresponding to the rack, and the rack is arranged through the channel. The center of the adjustment plate is connected to a rotating rod through a driving mechanism, and the rotating rod is located below the adjustment plate. The rotating rod is rotatably connected to the positioning sleeve through two first bearings, and the upper end of the positioning sleeve is fixedly connected to the lower end of the adjustment plate through a connecting block.

[0004] The above technical solution can drive the adjustment plate to adjust the height by setting a positioning plate, a support rod, a movable sleeve, an adjustment plate, a fixed plate, a rack, a rotating rod, a positioning sleeve, a connecting block and a gear, so as to meet different usage conditions.

[0005] However, the above device does not have any protective components on the top. During high-altitude operations, a support frame without a top protective component can easily cause workers to step on empty space or objects to fall, increasing the risk of falling objects from high altitudes. Moreover, when workers suffer from back pain due to long-term work, they have nothing to rely on, resulting in reduced work efficiency. Therefore, we propose an adjustable support frame.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] like Figure 1 and Figure 2 As shown, an adjustable support frame includes a base 1, a lifting component 2 is provided on the top of the base 1, a top plate 3 is provided on the top of the lifting component 2, a protective component 4 is provided on the top of the top plate 3, and the protective component 4 includes a support rod 41, a fixed rod 42 is fixedly connected to the top of the support rod 41, a sliding rod 43 is slidably connected to the fixed rod 42, a limiting hole 45 is provided on the fixed rod 42, a latch 46 is inserted into the limiting hole 45, a guardrail 44 is fixedly connected to the top of the sliding rod 43, a fourth rotating shaft 49 is rotatably connected between the fixed rods 42, a notch is provided on the guardrail 44, and the notch of the guardrail 44 A holder 47 is provided at the guardrail 44, and a buckle 48 is provided on one side of the guardrail 44 near the holder 47. The buckle 48 is clamped in the holder 47. By providing the protection component 4, when the staff needs to perform high-altitude operations, the guardrail 44 is driven to open by the fourth rotating shaft 49. When the staff enters, the protection component 4 is closed by the holder 47 and the buckle 48. Then, the raised guardrail 44 is fixed and limited by the limit hole 45 and the latch 46, so as to prevent the staff from slipping when performing high-altitude operations and provide reliable support for the staff when they are tired.

[0035] Furthermore, if Figure 1 and Figure 3 As shown: the lifting assembly 2 includes a fixed seat 21, a first rotating shaft 22 is rotatably connected to the fixed seat 21, the first rotating shaft 22 is connected to the first connecting rod 23, the first connecting rod 23 is connected to the second rotating shaft 24, the second rotating shaft 24 is rotatably connected to the second connecting rod 25, a third rotating shaft 26 is provided on the second connecting rod 25, the third rotating shaft 26 is rotatably connected to the third connecting rod 27, the third connecting rod 27 is connected to the first rotating shaft 22, the top of the fixed seat 21 is connected to the top plate 3, the second connecting rod 25 is connected to the cross bar 28, and a power assembly 5 is provided on the side of the base 1 near the cross bar 28. The power assembly 5 includes a cross plate 51, and a hydraulic cylinder 52 is provided on the top of the cross plate 51. The output end of the hydraulic cylinder 52 is connected to the cross bar 28. By setting the lifting assembly 2, turning on the hydraulic cylinder 52 drives the cross bar 28 to rise and fall, thereby driving the top plate 3 at the top to rise and fall, so as to facilitate the lifting of the staff to the designated position for high-altitude operations;

[0036] The above scheme also has the problem that when the lifting movement is carried out, the weight of the staff will bring a certain pressure to the top plate 3 and thus transmit it to the lifting component 2, which should be supported, such as Figure 3 As shown: a telescopic rod 6 is provided on the top of the base 1. Four telescopic rods 6 are provided. The four telescopic rods 6 are respectively located at the four corners of the top of the base 1. The top of the telescopic rod 6 is connected to the top plate 3. By providing the telescopic rod 6, the top plate 3 is supported during the lifting process to prevent excessive pressure from causing damage to the lifting component 2;

[0037] In the above scheme, if the road surface is uneven, the bottom of the support frame should be adjustable according to the road surface conditions, such as Figure 4 As shown: an adjustment assembly 7 is provided at the bottom of the telescopic rod 6, and the adjustment assembly 7 includes a sleeve 71. A threaded section 72 is provided on the side of the telescopic rod 6 close to the sleeve 71. The sleeve 71 is threadedly connected to the threaded section 72. A universal shaft 73 is provided on the sleeve 71. An extension rod 74 is rotatably connected to the universal shaft 73. The bottom of the extension rod 74 is connected to a chassis 75. By setting the adjustment assembly 7, when a corner of the road is too low, the sleeve 71 is screwed to drive the chassis 75 down, so that the support frame remains in a balanced state.

[0038] Furthermore, if Figure 4 As shown: four adjustment components 7 are provided, and the four adjustment components 7 are respectively located at the four corners of the bottom of the base 1. By providing four adjustment components 7, the four corners of the support frame can be adjusted.

[0039] Working principle: Figure 1 - Figure 4As shown, by setting the protection component 4, when the staff needs to perform high-altitude operations, the guardrail 44 is driven to open through the fourth rotating shaft 49. When the staff goes in, the protection component 4 is closed by setting the socket 47 and the buckle 48, and then the raised guardrail 44 is fixed and limited by the set limiting hole 45 and the latch 46 to prevent the staff from stepping on the air and slipping when performing high-altitude operations, and also provide support for the staff when they are tired. By setting the lifting component 2, the hydraulic cylinder 52 is turned on to drive the cross bar 28 to rise and fall, thereby driving the top plate 3 to rise and fall, which is convenient for lifting the staff to the designated position for high-altitude operations. By setting the telescopic rod 6, the top plate 3 is supported during the lifting process to prevent excessive pressure from causing damage to the lifting component 2. By setting the adjustment component 7, when a corner of the road surface is too low, the sleeve 71 is screwed to drive the chassis 75 to descend, so that the support frame remains in a balanced state.
