Description

Technical Field

[0001] This application belongs to the field of construction scaffolding technology, specifically a building construction scaffolding. Background Technology

[0002] During the main construction and interior decoration of a building, various raw materials are used, such as bricks, bagged cement, precast slabs, and decorative panels. Most of these building materials are transported to the construction site by trucks. Once the trucks reach the unloading point, scaffolding is used to transfer the raw materials from the trucks to the ground. Using scaffolding for material transfer is easier and less labor-intensive than manual handling.

[0003] The conventional method for unloading raw materials is as follows: first, a crane is used to lift the material from the transport vehicle to a handcart, which then transports the material to the unloading location. Once at the unloading location, the material is then lifted from the handcart to the ground. On the one hand, this method requires two lifting operations. When the unloading location and the raw material storage location are far apart, cranes need to be installed at both locations to complete the unloading operation, which reduces operational convenience. On the other hand, existing cranes are bulky and inconvenient to transport between different sites. Utility Model Content

[0041] Please refer to the following: Figures 1 to 8 The following describes the building construction scaffolding provided in the embodiments of this application.

[0042] The building construction scaffold provided in this application includes a base frame 10, a support arm 20, a first telescopic member 30, a boom 40, and a second telescopic member 50.

[0043] The base frame 10 is constructed from shaped steel or steel plates to form a frame structure. The bottom of the base frame 10 has three or more casters 11. One side of the base frame 10 has a handle 12. The upper part of the base frame 10 has a receiving cavity, and a fixed seat 13 is provided on one side of the receiving cavity. The support arm 20 is located on the side of the receiving cavity opposite to the fixed seat 13, and its bottom is hinged to the base frame 10. One end of the first telescopic member 30 is hinged to the inner wall of the receiving cavity, and the other end is hinged to the support arm 20 through a detachable first movable shaft. One end of the boom 40 is hinged to the top of the support arm 20, and the other end is connected to a hook 41. The boom 40 has a connecting part that is detachably connected to the fixed seat 13. One end of the second telescopic member 50 is hinged to the support arm 20, and the other end is hinged to the boom 40.

[0044] Building construction scaffolding has such Figure 1 , Figure 4 and Figure 5 The usage status shown, and as Figure 6 The folded state is shown. When in the folded state, the first movable shaft is removed, the first telescopic member 30 can rotate about its hinge axis with the base frame 10 into the receiving cavity, and the support arm 20 can rotate about its hinge axis with the base frame 10 until the connecting part reaches the connection position with the fixed seat 13. The building construction scaffold in the folded state has a lower height and occupies less space, making it easier to move and transport.

[0045] Compared with the prior art, the beneficial effects of the building construction scaffolding provided in this application are:

[0046] The building construction scaffold provided in this application includes a base frame 10, a support arm 20, a first telescopic member 30, a boom 40, and a second telescopic member 50. The base frame 10 has casters 11 at its bottom and a handle 12 on its side. The support arm 20 is connected to the base frame 10 via the first telescopic member 30, and the boom 40 is connected to the support arm 20 via the second telescopic member 50. The first telescopic member 30 and the second telescopic member 50 can change the angle and height of the support arm 20 and the boom 40 to realize the lifting and lowering of goods.

[0047] From an operational convenience perspective, since the base frame 10 has casters 11 and handles 12, after the lifting operation is completed, the construction crane can be directly pushed to the unloading position. The construction crane simultaneously serves the functions of lifting and transportation, eliminating the need for intermediate transfers and reducing the number of lifting operations. From the perspective of transportation between different sites, the base frame 10 has a fixed seat 13, and the first telescopic member 30 is hinged to the support arm 20 via a detachable first movable shaft. When transportation is required, the first movable shaft can be removed, and the crane can be quickly folded into a more compact folded state, reducing its size and facilitating transportation and storage. After folding, the first telescopic member 30 is stored in the receiving cavity, and the support arm 20 and the boom 40 are fixed to the base frame 10, ensuring overall structural stability and reducing the risk of component damage during transportation.

[0048] The base frame 10 adopts a rectangular steel frame structure, with three or more casters 11 installed at the bottom. The casters 11 can be swivel casters with brakes or other types of wheels, as long as they can provide stable support. A handle 12 is provided on one side of the base frame 10. The handle 12 can be made of steel pipe with a non-slip rubber coating to improve grip. Two handles 12 are provided when two hands are needed for gripping.

[0049] The upper part of the base frame 10 has a receiving cavity, which is a groove or box-shaped structure welded from steel plates. The volume of the receiving cavity should be able to completely accommodate the first telescopic member 30 after it has retracted. A fixing seat 13 is provided on one side of the receiving cavity. The fixing seat 13 is a perforated steel plate or a hook-shaped structure, which can be connected to the boom 40 when folded, so that the base frame 10, the support arm 20 and the boom 40 form an approximately triangular structure, which reduces the volume and improves the stability, making it easier to load and transport.

[0050] The support arm 20 adopts a high-strength aluminum alloy or steel tubular structure. The bottom is hinged to the base frame 10 by a pin. Rolling bearings can be installed at the hinge point to ensure smooth rotation. During maintenance, lubricating oil is added to the rolling bearings for maintenance.

[0051] The first telescopic component 30 and the second telescopic component 50 can be hydraulic cylinders, pneumatic cylinders, or electric push rods (the drive method is selected according to the on-site power source). One end of the first telescopic component 30 is hinged to the inner wall of the receiving cavity via a pin, and the other end is hinged to the support arm 20 via a detachable first movable shaft. The first movable shaft can be a quick-release pin or bolt. One end of the second telescopic component 50 is hinged to the support arm 20 via a pin, and the other end is hinged to the boom 40 via a pin. The operation of the first telescopic component 30 and the second telescopic component 50 is independent of each other and does not affect each other. They can be controlled via a control panel or remote control.

[0052] The boom 40 is a telescopic or fixed steel boom, with one end hinged to the top of the support arm 20 via a pin, and the other end connected to a hook 41 for lifting goods. The hook 41 is a standard component of the prior art. The boom 40 is provided with a connecting part (such as a hole or hook groove) for detachable connection with the fixed base 13. In the folded state, the connecting part remains connected to the fixed base 13, such as by a pin or a lock.

[0053] Please see Figure 2 and Figure 4 In some possible embodiments, mounting plates 14 are provided on both sides of the base frame 10. The mounting plates 14 are circular, made of steel plate, and have a thickness of 5-10mm. The mounting plates 14 are provided with a plurality of first mounting holes 141 at intervals along the arc direction, for example, 4-8 holes, with a hole diameter of 10-20mm.

[0054] The building construction scaffold also includes two steel support legs 60 arranged opposite each other. Each support leg 60 corresponds to a mounting plate 14 and can rotate around the axis of the corresponding mounting plate 14. Each support leg 60 has a second mounting hole, and a first limiting pin 61 is detachably installed within both the second mounting hole and the corresponding first mounting hole 141. The bottom of each support leg 60 is equipped with a caster wheel 11, which can be a universal wheel. When the support leg 60 rotates to the desired angle, the second mounting hole aligns with the corresponding first mounting hole 141, and the first limiting pin 61 (such as a spring pin or bolt) can be inserted to fix the position of the support leg 60. The caster wheel 11, which can be a universal wheel, is installed at the bottom of the support leg 60 and has a braking function.

[0055] In this embodiment, the outrigger 60 can be rotated to adjust the support angle, enlarging the support base and enhancing stability during hoisting, preventing the hoist from tipping over, especially suitable for uneven ground. The outrigger 60 and the mounting plate 14 are fixed by the first limiting pin 61, which has a simple and reliable structure, is easy to operate, and allows for quick locking of the outrigger 60 position. Figure 6 As shown, when in the folded state, the support leg 60 can be rotated to a position close to the base frame 10, reducing space occupation and facilitating transportation.

[0056] Please see Figure 1 and Figure 3The underframe 10 is also equipped with a towing bracket 15 on one side, which can be connected to a transport vehicle and towed to a designated location by the transport vehicle. The towing bracket 15 is an existing structure and is fixed to the underframe 10 by bolts or welding.

[0057] Please see Figure 6 and Figure 8 To prevent the first telescopic member 30 from swaying significantly within the receiving cavity during the transfer of the building construction scaffold, top rods 16 are threadedly connected to the two side walls of the receiving cavity opposite to the first telescopic member 30 (i.e., the left and right side walls of the receiving cavity). When in the folded state, the top rods 16 abut against the first telescopic member 30.

[0058] The position of the push rod 16 can be adjusted by screwing it in or out. When in the folded state, the first telescopic member 30 is housed in the receiving cavity, and the push rod 16 is tightened so that its end abuts against the surface of the first telescopic member 30. The push rod 16 can press the first telescopic member 30 to prevent it from shaking or shifting in the receiving cavity, ensuring stability during transportation and reducing component wear and noise.

[0059] Please see Figure 1 , Figure 4 and Figure 5 The boom 40 has a groove at the end away from its hinge point with the support arm 20. The building construction scaffold also includes a slide rod 70, which slides in conjunction with the groove. A hook 41 is located at the end of the slide rod 70 away from the boom 40 via a connector, allowing adjustment of the extension length of the slide rod 70. The movement of the slide rod 70 can be adjusted manually or driven by a drive structure (such as an electric telescopic rod).

[0060] Please see Figure 1 , Figure 4 and Figure 5 The slide rod 70 has multiple third mounting holes along its length, and the side wall of the slide groove has multiple fourth mounting holes that penetrate its own wall thickness. Second limiting pins 71 are detachably installed in the third mounting holes and the corresponding fourth mounting holes. When the slide rod 70 slides to the desired position, the third mounting holes align with the corresponding fourth mounting holes, and the second limiting pins 71 (such as spring pins or bolts) can be inserted to fix the position of the slide rod 70.

[0061] A fifth mounting hole is provided at the end of the slide rod 70 away from the boom 40. The hook 41 is mounted in the fifth mounting hole via a detachable second movable shaft 72, and the slide rod 70 forms the connecting part. When in the folded state, the hook 41 is removed, and the end of the slide rod 70 can be connected to the fixed seat 13. The second movable shaft 72 is removed from the hook 41 and inserted into the fifth mounting hole of the fixed seat 13 and the slide rod 70, connecting the slide rod 70 to the fixed seat 13. Using the same second movable shaft 72 to connect the hook 41 or the fixed seat 13 simplifies the hanger structure, reduces the number of parts, and lowers costs and maintenance difficulty.

[0062] The second telescopic member 50, hinged to the boom 40, has a third movable shaft at one end. This third movable shaft is detachably mounted, and its arrangement is similar to that of the first movable shaft, so it will not be described further here. When the second telescopic member 50 affects the folding of the hanger, the third movable shaft can be removed. The boom 40 has a storage cavity on its side adjacent to the support arm 20. When folded, the second telescopic member 50 is at least partially housed within this cavity, further compressing the volume of the folded hanger. The second telescopic member 50 can be temporarily secured to the support arm 20 using ropes, cable ties, or similar means.

[0063] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
