Of course, the telescopic extension rods 12 can also be adjusted in this way, or, the sliding end of the base body 11 is provided with a positioning hole, one end of the telescopic extension rod 12 is provided with a positioning hole, and the other end is provided with multiple positioning holes, and the different positioning holes are aligned through the positioning hole at the sliding end of the base body 11 and the end of the telescopic extension rod 12 with multiple positioning holes, so as to adjust the length. Among them, the base body 11 can be a square columnar structure with a hollow interior. The telescopic extension rod 12 can also be a square columnar structure with a hollow interior. The base body 11 and / or the telescopic extension rod 12 are made of steel plates, and a 50mm thick carbon steel plate can be used as the main material. For example, the telescopic support base 1 uses a 50mm thick carbon steel plate as the main material, and the total length is 2 meters. The base body 11 can be 1.2 meters long, 20 cm wide, and 15 cm high. The telescopic extension rod 12 can be divided into two sections, each section is 20 cm. One end of the base body 11 can be extended by 40 cm, and the two ends can be extended by 80 cm in total.
[0028] In this embodiment, the telescopic pull connection mechanism 2 may include: at least two connection columns and cross links; wherein at least two connection columns are arranged at intervals; a cross link is provided between any two adjacent connection columns, and its two ends are respectively hinged to the two adjacent connection columns, for adjusting the distance between the two adjacent connection columns. Specifically, two connection columns are respectively connected to the two telescopic support bases 1, and other connection columns can be arranged between the above two connection columns at intervals, which can further increase the stability of the telescopic pull connection mechanism 2. A cross link is provided between any two adjacent connection columns, that is, a plurality of groups of pairs of connection rods, the two pairs of connection rods are arranged crosswise, and are hinged at the intersection position, and the two ends of the connection rod are respectively hinged to the two adjacent connection columns, and the distance between the two adjacent connection columns can be adjusted by adjusting the angles of the two connection rods, thereby realizing the telescopic pull connection mechanism 2 to telescope and unfold, thereby realizing the adjustment of the distance between the two telescopic support bases 1, and also providing auxiliary support for the storage part 4 in the middle position. Of course, in other embodiments, the telescopic pulling connection mechanism 2 can also be a sliding door structure, and can be made of a 20mm thick carbon steel plate as the material.
[0029] Continue to see Figure 1 to Figure 2 The hand-pull tape measure type binding mechanism 3 includes: a binding rope 31, an elastic rope assembly 32 and a push-fix key 33; wherein the binding rope 31 passes from the end of the telescopic support base 1 to the outside of the telescopic support base 1, and the binding end of the binding rope 31 placed outside the telescopic support base 1 is provided with a connecting fastener 34, which is used to realize the connection between the binding ends of the two binding ropes 31 to realize the binding of the to-be-stored items 4; the elastic rope assembly 32 is arranged inside the telescopic support base 1, and the telescopic support base 1 is connected to the connecting end of the binding rope 31 placed inside the telescopic support base 1, which is used to elastically deform the binding rope 31 when it is stretched, and can apply a reset force to the binding rope 31 so that the binding rope 31 can be retracted into the telescopic support base 1.
[0030] Specifically, each hand-pull tape measure type binding mechanism 3 can be provided with an elastic rope assembly 32 to recycle the binding rope 31. Of course, the two binding ropes 31 on the telescopic support base 1 can also share an elastic rope assembly 32, that is, the elastic rope assembly 32 can recycle the two binding ropes 31 at the same time. The elastic rope assembly 32 is arranged inside the telescopic support base 1, especially the base body 11. The connecting end of the tying rope 31 placed inside the telescopic support base 1 is connected to the elastic rope assembly 32, and the base body 11 and the ends of each telescopic extension rod 12 are provided with stretching holes. The tying rope 31 passes through the stretching holes at the ends of the base body 11 and each telescopic extension rod 12 in turn and extends to the outside. The tying end of the tying rope 31 placed outside the telescopic support base 1 is provided with a connecting fastener 34. Not only can the storage item 4 be tied through the detachable connection between the two connecting fasteners 34 at the tying ends of the two tying ropes 31, but the tying rope 31 can also be limited to prevent the tying rope 31 from being completely recovered to the inside of the telescopic support base 1. When the connecting fastener 34 is stretched, the tying rope 31 can pull the elastic rope assembly 32 and gradually pull it out of the telescopic support base 1. At the same time, the elastic rope assembly 32 will undergo elastic deformation and apply a reset force to the tying rope 31. After the connecting fastener 34 is connected, the elastic rope assembly 32 can drive the tying rope 31 to retract to ensure the stability of the tying. At the same time, after the connecting fastener 34 is unlocked, the elastic rope assembly 32 can pull the tying rope 31 to retract so as to be retracted into the telescopic support base 1. The press-fix key 33 can be set on the telescopic support base 1, and the press-fix key 33 also extends to the inside of the telescopic support base 1. The press-fix key 33 has a fixed state and a free state. When pushed to the fixed state, the press-fix key 33 applies an extrusion force to the binding rope 31, so that the binding rope 31 can be locked in the stretched position stretched by the external force, that is, when the press-fix key 33 is pushed to the fixed state, the binding rope 31 can only be stretched outward under the action of external force, and cannot be retracted and rolled into the inside of the telescopic support base 1; when pushed to the free state, the extrusion pressure on the binding rope 31 is released, so that the binding rope 31 can be rolled up under the action of the reset force of the elastic rope assembly 32, so that it can be rolled up into the telescopic support base 1. Among them, the binding rope 31 can be a steel rope, for example, with a diameter of 1.5 cm and a length of 1.5 meters, and is made of high-carbon steel as the main material. This hand-pulled steel rope is also called a jack rope or a jack rope; the connecting fastener 34 can be a ring structure, which is used to stretch the binding rope 31, and an aluminum alloy fastener can be used. This material has light weight, high strength and strong corrosion resistance; the press-fixed key 33 can be made of 45 steel as the main material. This material has the characteristics of long service life and good key elasticity.
[0031] In this embodiment, the elastic rope assembly 32 may include: a fixed column and a spring; wherein the fixed column is arranged inside the telescopic support base 1; the spring is wound on the fixed column, and the fixed end of the spring is connected to the fixed column, and the spring is also connected to the lashing rope 31, and is used to generate bending elastic deformation when the lashing rope 31 is stretched, so that the lashing rope 31 can be rolled up. Specifically, the fixed column can be fixed inside the base body 11, the spring is wound on the fixed column, and the fixed end of the spring is connected to the fixed column, and the spring is also connected to the connecting end of the lashing rope 31, and is used to generate bending elastic deformation when the lashing rope 31 is stretched, so that the lashing rope 31 can be rolled up. The elastic rope assembly 32 can be made of a 50mm thick carbon steel plate with an axial diameter of 2cm. This material has the characteristics of high strength, high hardness, and wear resistance, and is suitable for scenes with heavy pressure and load.
[0032] Sample method for the building material storage device:
[0033] Put the storage device on the work surface, then put the building materials to be stored and hoisted, that is, the storage pieces 4, into the storage device, that is, the two telescopic support bases 1, and finally securely connect the hand-pull connection fasteners 34, and then safely hoist. When the construction workers want to lengthen the length of the telescopic support base 1, they can lengthen the base by extending the telescopic extension rod 12, and then equip the building materials, and finally pull out the tying rope 31 by hand and securely connect the fasteners 34, so that the building materials to be hoisted can be fixed. Figure 3 As shown, preventing the falling phenomenon during the hoisting operation can prevent casualties among on-site construction workers. As long as the on-site operators operate in a standardized manner, the construction tasks can be completed safely and efficiently. Finally, after completing all the construction tasks, all the storage devices can be manually restored and placed neatly, and the space occupied is also very small, which is convenient for loading and unloading.
[0034] It should be noted that the device should be maintained and lubricated on time, all components and devices should be inspected in detail before construction, with emphasis on checking whether the connection fasteners 34 are functioning properly, etc., to prevent safety accidents during construction and ensure that construction tasks are completed safely and efficiently.
[0035] In summary, the building material storage device provided in this embodiment supports the to-be-stored pieces 4 through two telescopic support bases 1, and can be adjusted in length to adapt to the width of the to-be-stored pieces 4. The distance between the two telescopic support bases 1 can also be adjusted by telescopic adjustment of the telescopic pull connection mechanism 2 to adapt to the length of the to-be-stored pieces 4. The four hand-pull tape-measure-type tying mechanisms 3 are used to perform tape-measure-type stretching, so that when the to-be-stored pieces 4 are placed on the two telescopic support bases 1 for storage, the two ends of the to-be-stored pieces 4 are respectively tied to the two by stretching the four hand-pull tape-measure-type tying mechanisms 3. On the telescopic support base 1, the binding and fixing of the items to be stored 4 is realized. The device can not only meet the functional requirements of traditional high-altitude lifting operations, but also the safety of the machinery is relatively high during the process of lifting building materials, and the operation is relatively convenient and quick, which greatly improves the work efficiency of on-site construction, and solves the problem that the existing high-altitude lifting operations use elevators and lifting vehicles for construction operations and use straps or steel belts to bind building materials, which are easy to loosen and fall, causing casualties. This storage device optimizes high-altitude lifting operations and has good flexibility. In addition, the device is fully functional. In addition to the safe and reliable lifting and storage, it is also safe and reliable during transportation and storage, and has the advantages of overall beauty in stacking and storage; it also greatly facilitates the construction of high-altitude lifting operations, solves the problem of low efficiency of high-altitude lifting operations, and increases the safety of construction; at the same time, the device has a simple principle, is easy to operate, and is convenient and quick to maintain in the later stage.
