Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, to a guardrail for building construction. Background Art

[0002] In order to avoid accidents to construction workers at the construction site, construction guardrails are usually set up on the periphery of the construction site to prevent construction workers from accidentally falling into deep foundation pits. They can also prevent objects falling from high altitudes from injuring construction workers. Therefore, construction guardrails are an indispensable safety device at the construction site.

[0003] When installing a guardrail, first determine the specific location and range where the guardrail needs to be installed, conduct on-site surveys and markings, prepare the required guardrail materials, and build a bracket at the location where the guardrail needs to be installed according to design requirements. Install the prefabricated guardrail components on the built bracket in sequence, and then use screws or welding to connect and fix the various components. Usually, the protection range of the guardrail depends on the size of the guardrail itself, but different construction site buildings have different heights. Guardrails of fixed height cannot adapt to building structures with different height requirements, which limits their application range in different scenarios. As a result, in some cases, the area that needs to be protected cannot be fully covered, thereby affecting the safety of construction and use. If guardrails of different heights are customized according to different construction sites, the cost and construction period will increase. Therefore, a soil leveling equipment based on construction is urgently needed to solve the above problems. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a guardrail for building construction, which has the advantages of automatic adjustment and convenient movement.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a guardrail for construction, comprising a guardrail body, a fixing frame being fixedly mounted on the outer wall of the guardrail body;

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.

[0027] like Figures 1 to 5 As shown, the utility model provides a guardrail for construction, comprising a guardrail body 1, on the outer wall of which a fixing frame 2 is fixedly mounted;

[0028] The power mechanism is fixedly mounted on the left outer wall of the fixing frame 2;

[0029] An adjusting mechanism is rotatably mounted on the inner wall of the fixing frame 2;

[0030] Among them, the adjustment mechanism includes a threaded rod 3 rotatably installed on the inner wall of the fixed frame 2, the left end of the threaded rod 3 extends to the outside of the fixed frame 2, and two sliding blocks 4 are threadedly sleeved on the outer wall of the threaded rod 3. The tops of the two sliding blocks 4 are respectively hingedly installed with rectangular bars 5, and the tops of the two rectangular bars 5 are both hingedly installed with T-shaped blocks 6.

[0031] By setting up an adjustment mechanism, the threaded rod 3 rotates to drive the two sliding blocks 4 to move along a preset direction. Through the rectangular bar 5, the sliding block 4 moves to drive the rectangular bars 5 to move closer to or away from each other. The rectangular bar 5 drives the T-block 6 to move up and down according to actual needs. Compared with the traditional device, the protection range of the guardrail is expanded upward or reduced downward through the change in the height of the T-block 6, which not only improves the protection performance of the guardrail but also improves the use performance of the device.

[0032] When it is necessary to install the guardrail, the staff first moves the guardrail to the designated position and then starts the motor 12. The output shaft of the motor 12 drives the gear 2 13 to rotate. The gear 2 13 and the gear 1 11 are meshed. The gear 2 13 drives the gear 1 11 to rotate. The gear 1 11 drives the threaded rod 3 to rotate. The rotation of the threaded rod 3 drives the two sliding blocks 4 to move along the preset direction. Through the rectangular bar 5, the sliding block 4 moves to drive the rectangular bar 5 to move closer to or away from each other. The rectangular bar 5 drives the T-block 6 to move up and down according to actual needs, thereby adjusting the height of the guardrail.

[0033] Among them, two hydraulic cylinders 14 are fixed at the bottom of the fixed frame 2, and a bottom frame 15 is fixedly installed on the output shafts of the two hydraulic cylinders 14;

Compared with the traditional device, when the guardrail needs to be moved, it is only necessary to start the hydraulic cylinders 14 to lower the base frame 15 and the moving wheels 17. The staff can easily push the device to move its position. When it is not necessary to move, the moving mechanism can be retracted to make the guardrail body 1 directly and stably contact the ground, thereby improving the wide range of use of the device.

[0037] When the position of the guardrail needs to be changed, the staff can start the two hydraulic cylinders 14, and the output shafts of the two hydraulic cylinders 14 drive the base frame 15 to move downward, so that the four moving wheels 17 are in contact with the ground, and then push the guardrail to the designed location, and then start the two hydraulic cylinders 14 again, and the output shafts of the two hydraulic cylinders 14 drive the base frame 15 to move upward, so that the four moving wheels 17 are away from the ground, so that the bottom of the guardrail body 1 is in contact with the ground.

[0038] Among them, the power mechanism includes a motor 12 fixedly mounted on the left outer wall of the fixing frame 2, a gear 2 13 is fixedly mounted on the output shaft of the motor 12, a gear 1 11 is fixedly mounted on the outer wall of the threaded rod 3, and the gear 1 11 is meshed with the gear 2 13.

[0039] By starting the motor 12, the output shaft of the motor 12 drives the gear 2 13 to rotate, the gear 2 13 and the gear 1 11 are meshed, the gear 2 13 drives the gear 1 11 to rotate, and the gear 1 11 drives the threaded rod 3 to rotate, thereby providing power support for the device.

[0040] A limiting slide bar 9 is fixedly installed on the inner wall of the fixing frame 2 , and the limiting slide bar 9 passes through the two sliding blocks 4 and is slidably connected with the two sliding blocks 4 .

[0041] By providing the limiting sliding rod 9, the sliding block 4 can be effectively limited when it moves, thereby improving the stability and accuracy of the device.

[0042] Among them, guardrail needles 7 are fixedly installed on the top of the T-block 6, and the guardrail needles 7 are arranged at intervals from left to right.

[0043] By providing the guardrail needle 7, pedestrians can be effectively prevented from climbing the guardrail, thereby preventing unnecessary safety accidents from occurring, thereby improving safety.

[0044] A rectangular groove 10 is provided on the T-block 6 , and a protective net 8 is fixedly installed in the rectangular groove 10 .

[0045] The rectangular groove 10 is provided to provide a wide field of vision, so that the staff can observe the dynamic environmental changes outside the guardrail at any time, and the protection net 8 can also prevent pedestrians from throwing garbage.

[0046] There are two threaded rods 3, two rectangular bars 5, and two limit slide bars 9, and four slide blocks 4 and four support bars 16.
