Description

Technical Field

[0001] The utility model relates to the technical field of boom wrenches, in particular to a boom wrench. Background Art

[0002] In construction, booms are required in ceiling installation, wall panel installation, stone curtain wall installation, light steel keel installation, and fresh air system installation. Generally, they are installed vertically downward from the inner top wall of the wall to achieve the load-bearing effect. During installation, first, a hole is drilled in the inner top wall of the wall, and then an extrusion nut, an expansion tube, and a plug are installed at one end of the boom. The end with the extrusion nut, expansion tube, and plug is inserted into the hole in the inner top wall of the wall, and then a wrench is used to tighten the extrusion nut. Due to the pressure of the extrusion nut and the plug, the expansion tube explodes inside the hole, thus achieving the effect of stably connecting the boom to the inner top wall of the wall. In the existing boom installation process, the problems are as follows: during the existing boom installation process, workers need to stand on a ladder or a scaffold for construction, which not only poses safety hazards but also limits the construction space because the human body is close to the top wall of the wall. The worker's arm is always in a suspended state, consuming a large amount of physical strength. When using a wrench to tighten the extrusion nut, the angle of tightening is limited each time the wrench engages with the tightening nut. Then, the wrench needs to be re-engaged with the tightening nut to tighten again. It takes multiple repetitions to stabilize the boom, resulting in a slow rotation efficiency. At the same time, when using the existing wrench to tighten the tightening nut, based on this problem, a boom wrench needs to be designed to solve the above problems. Summary of the Utility Model

[0003] The utility model provides a boom wrench which can directly install the boom on the ground after drilling the hole in the inner top wall of the wall, without the need to stand at a high place for construction, and can improve the construction efficiency at the same time.

[0004] The technical problems solved by the utility model are realized by adopting the following technical solutions:

[0005] A boom wrench includes a nut clamping plate for driving the extrusion nut on the boom to rotate and a wrench bracket for easy holding. The lower part of the nut clamping plate is fixedly connected with a nut backing plate. The wrench bracket is connected to the lower part of the nut backing plate and extends vertically downward. The nut backing plate has a notch one, the width of the notch one is greater than the outer wall diameter of the boom main body and less than the inner circumscribed circle diameter of the outer wall of the extrusion nut. The central position of the nut clamping plate has a clamping groove adapted to the extrusion nut. The edge position of the nut clamping plate has a notch two, the width of the notch two is not less than the width of the notch one and its opening direction is the same as that of the notch one.

[0006] Preferably, the width of the notch two is not greater than the inner circumscribed circle diameter of the outer wall of the extrusion nut.

[0007] Preferably, the bottom of the wrench bracket is provided with hexagonal steel columns, and the axis of the hexagonal steel columns is the same as the axis of the nut clamping plate.

[0008] Preferably, a crank is provided at the bottom of the wrench bracket.

[0009] Preferably, the wrench bracket and the nut backing plate are detachably connected.

[0010] Preferably, the wrench bracket has a receiving space capable of receiving the boom body.

[0011] The beneficial effects of the present utility model are as follows: By providing a wrench bracket, a nut backing plate and a nut clamping plate, it enables personnel to install the boom while standing on the ground. At the same time, during construction, continuous tightening work can be achieved through an electric device or a crank, thereby increasing the construction efficiency.

Detailed implementation manners

[0026] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations.

[0027] Refer to Figure 1 and Figure 2 , which show the existing suspension rod structure and the tool wrench for installing the suspension rod. In order for those skilled in the art to know the innovative points of the present utility model, first, the installation process of the traditional suspension rod will be introduced. The suspension rod includes the main body 1 of the suspension rod, on the surface of which there is a thread. Before installation, first, a hole (not shown in the figure) is opened on the inner top wall of the wall, and then the tightening nut 2 is threadedly fitted and installed on the main body 1 of the suspension rod. Subsequently, an expansion tube 3 is sleeved on the tightening nut 2. Finally, a plugging head 4 is installed at one end of the main body 1 of the suspension rod. There is also a threaded fit between the plugging head 4 and the main body 1 of the suspension rod. After the suspension rod structure is assembled, it forms a state as shown in Figure 1 . With the help of a ladder or a scaffold, climb to a height convenient for work, and insert the end of the suspension rod structure with the plugging head 4 into the hole on the inner top wall of the wall. When inserting, ensure the insertion depth. At least most of the expansion tube 3 should be inside the hole. Then use the traditional wrench 5 to rotate the tightening nut 2 to the state as shown in Figure 2 . The tightening direction is to move towards the plugging head 4. Since the expansion tube 3 is between the plugging head 4 and the tightening nut 2, it will be squeezed and deformed, expanding towards the surroundings, so that the expansion tube 3 is stable with the inside of the hole, achieving the effect of the suspension rod bearing weight.

[0028] As can be seen from the above, during the installation of the existing hanging rod, not only is it necessary to work at heights, but also restricted by the traditional wrench 5. The angle of each arm twist is limited, and it is necessary to match and disengage the slot 801 of the traditional wrench 5 with the tightening nut 2 multiple times to achieve the firm installation of the hanging rod. The installation efficiency is slow. Based on this problem, the present utility model designs a hanging rod wrench to solve the above problems and assist workers to more conveniently carry out the hanging rod installation operation.

[0029] Reference Figures 3 to 12 , is the structure of the hanging rod wrench of the present utility model, which includes a wrench support 6 with sufficient length to meet the installation of the hanging rod by personnel during ground construction, and also has a nut backing plate 7 and a nut clamping plate 8 installed on the top of the wrench support 6. Among them, the top of the wrench support 6 is connected to the bottom of the nut backing plate 7, and the upper part of the nut backing plate 7 is connected to the lower part of the nut clamping plate 8. Specifically, refer to Figure 6 , Figure 8 and Figure 12 are the specific structures of the wrench support 6, the nut backing plate 7 and the nut clamping plate 8. First, the nut backing plate 7 has a notch one 701. At the central position of the nut clamping plate 8, there is a slot 801 adapted to the tightening nut 2, and at its edge position, there is a notch two 802 with the same opening direction as the notch one 701. In order to facilitate the hanging rod wrench to stably convey the hanging rod structure into the high hole without detachment, and at the same time facilitate the detachment of the hanging rod from the hanging rod wrench after the hanging rod installation is completed, it is necessary to limit the dimensions of the notch one 701 and the notch two 802, that is, as shown in Figure 10 , the width h2 of the notch one 701 is greater than the outer wall diameter of the hanging rod main body 1 and less than the inscribed circle diameter h2 of the outer wall of the extrusion nut. Limiting the size of the notch one 701 can facilitate the hanging rod main body 1 to enter and exit the inside of the nut backing plate 7 through the opening of the notch one 701, and at the same time can lift the tightening nut 2 to facilitate sending the hanging rod main body 1 to a high place. The width of the notch two 802 is not less than the width of the notch one 701 and not greater than the inscribed circle diameter of the extrusion nut, which can prevent the tightening nut 2 of the hanging rod main body 1 from detaching from the slot 801 of the nut clamping plate 8 when the hanging rod main body 1 is lifted to a high place through the wrench support 6, and at the same time can facilitate the hanging rod to move out from the opening position of the notch two 802.

[0030] It should be further noted that the specific shape of the wrench support 6 is not limited. It can be composed of three rod-shaped bodies as shown in Figures 3 - 9 , or it can be composed of a cylinder as shown in Figure 11 and Figure 12 , but the wrench support 6 should at least have a receiving space 601 that can facilitate the placement of the hanging rod main body 1. As shown in Figure 3 , this receiving space 601 can facilitate the vertical placement of the hanging rod main body 1.

[0031] Further, a connecting plate 13 is provided at the lower part of the wrench support 6, and a driving member is installed at the bottom of the connecting plate 13. In order to improve the tightening speed of the bolt, by providing a crank 9 at the lower part of the wrench support 6 as the driving member, uninterrupted tightening work can be achieved. Also, the lower part of the wrench support 6 can be set as a hexagonal steel column 12 to cooperate with an electric device (as the driving member) for tightening work. Common electric devices adapted to the hexagonal steel column 12 are, for example, common pistol drill main engines. When the crank 9 is driven manually, reference can be made to Figure 5 , two sleeves are provided on the crank 9. Both the first sleeve 10 and the second sleeve 11 are rotatably connected to the outside of the crank 9. During use, a person's two hands respectively hold the two sleeves to perform the tightening work.

[0032] Further, in order to make the boom wrench applicable to various boom structures of different sizes, the nut backing plate 7 and the nut clamping plate 8 can be designed in a variety of corresponding sizes and connected to form an integral structure. The nut backing plate 7 and the wrench support 6 are designed to be detachably connected. The specific manner of the detachable connection is not limited, so that nut backing plates 7 and nut clamping plates 8 of different sizes can be installed on the wrench support 6 according to the on-site situation.

[0033] During use, place the tightening nut 2 of the boom structure inside the card slot 801 of the nut clamping plate 8, as Figure 3 shown. Since the card slot 801 can stabilize the tightening nut 2 of the boom structure, the boom will not separate from the wrench support 6. After the tightening is completed, pull down the wrench support 6 to make the card slot 801 disengage from the tightening nut 2, and move the wrench support 6 to make the boom main body 1 disengage from the accommodating space 601 at the positions of the first slot 701 and the second slot 802.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
