[0002] At present, on a building construction site, it is usually necessary to install large equipment such as bridge trays and air ducts on the floor slab. In order to make the installation of large equipment more stable, installation holes are usually drilled in the floor slab first, and then expansion bolts are inserted into the installation holes, and the large equipment is fixedly connected through the expansion bolts to increase the stability of the installation of the large equipment. In actual production, workers usually use a scissor lift or erect a scaffold for working at heights, and insert the expansion bolts into the pre-arranged installation holes.

[0003] Regarding the above related technologies, the workload of installing the expansion bolts themselves is less, while the workload of using a scissor lift or erecting a scaffold is greater. Therefore, the working hours consumed by using a scissor lift or erecting a scaffold are much greater than the working hours of installing the expansion bolts, which affects the installation efficiency. Moreover, workers working at heights have greater safety hazards. Therefore, in the process of installing expansion bolts, there are problems such as inconvenient installation of expansion bolts, low installation efficiency, and low safety during the installation operation process.

[0004] In view of this, it is indeed necessary to provide a technical solution of a portable high-efficiency installation device for expansion bolts to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a portable high-efficiency installation device for expansion bolts to solve the problems of inconvenient installation of expansion bolts, low installation efficiency, and low safety during the installation operation process.

[0006] In order to achieve the above purpose, a portable high-efficiency installation device for expansion bolts of the utility model adopts the following technical solutions:

[0010] As an optimization of a portable expansion bolt efficient installation device, the locking member includes a braking bolt, which passes through the side wall of the sleeve and abuts against the side wall of the striker.

[0011] As an optimization of a portable expansion bolt efficient installation device, the locking member includes a spring pin, and a plurality of positioning holes are arranged on the sleeve at intervals along the length direction of the sleeve, and the spring pin is inserted into the positioning hole.

[0012] As an optimization of a portable expansion bolt efficient installation device, a limiting groove is provided in the clamp, the limiting groove is hexagonal, and a sliding hole is provided through the bottom of the limiting groove.

[0025] The following combines the attached Figures 1-4 , and makes a further detailed description of the present application.

[0026] The present application provides a portable high-efficiency installation device for expansion bolts, and adopts the following technical solutions:

[0027] Embodiment 1

[0028] Refer to Figure 1 And Figure 2, the installation device includes a striking rod 1 and a sleeve 2. The striking rod 1 is in the shape of a solid cylinder, and the sleeve 2 is in the shape of a hollow circular tube. The inner diameter of the sleeve 2 is larger than the outer diameter of the striking rod 1. The sleeve 2 is sleeved and slides on the outside of the striking rod 1. A locking member 3 is installed on the striking rod 1, which can lock the relative position of the sleeve 2 and the striking rod 1, so that the striking rod 1 and the sleeve 2 are combined into a telescopic support rod. By adjusting the locking member 3, the support rod can be locked at different lengths, so as to adapt to the height requirements of different construction environments, which is convenient for the operator to install expansion bolts on the ground, reducing the risk of working at heights. At the same time, after the operation is completed, the locking member 3 is unlocked, and the striking rod 1 is retracted into the sleeve 2 to shorten the length of the support rod, which is convenient for storage and transportation, and is beneficial to the efficiency of expansion bolt installation operations.

[0029] Referring to Figure 1 and Figure 2 , a gun head 4 is installed at one end of the striking rod 1. The gun head 4 is in the shape of a hollow square tube. The gun head 4 is detachably sleeved on the end of one end of the striking rod 1. The outer wall of the striking rod 1 is inscribed in the inner wall of the gun head 4. A plurality of grippers 5 are welded around the gun head 4. In this embodiment, 4 grippers 5 are installed. The grippers 5 are in the shape of cylinders. The grippers 5 are used to place the expansion bolts to be installed. The expansion bolts include but are not limited to parts such as hex nuts and lead screws. One end of the lead screw away from the hex nut is connected to a large device. A plurality of limit pieces 41 are welded to the end face of the gun head 4 away from the striking rod 1. In this embodiment, there are 4 limit pieces 41 on the end face of the gun head 4. The limit pieces 41 are triangular. The limit pieces 41 can prevent the striking rod 1 from passing through the end face of the gun head 4. At the same time, through the limit pieces 41, the upward thrust of the striking rod 1 can be transmitted to the gun head 4, driving the gun head 4 and the grippers 5 to move upward, so as to push the expansion bolts on the grippers 5 into the installation position.

[0030] Referring to Figure 1 and Figure 2 , a thrust column 6 is slidably installed at the end of the sleeve 2 away from the striking rod 1. The thrust column 6 is in the shape of a cylinder. The outer diameter of the thrust column 6 is larger than the inner diameter of the sleeve 2. When the thrust column 6 moves upward and impacts the sleeve 2, the sleeve 2 pushes the striking rod 1 to impact the gun head 4, and the expansion bolts in the grippers 5 are stuffed into the installation position. The installation of the top expansion bolts is driven by the short-range movement of the bottom thrust column 6, which simplifies the operation difficulty of the installation operation and is beneficial to improving the efficiency of the installation operation.

[0031] When installing expansion bolts, place the expansion bolts on the grippers 5, install the gun head 4 at one end of the striking rod 1, install the sleeve 2 on the other end of the striking rod 1 to slide, adjust the overlapping length of the striking rod 1 and the sleeve 2 according to the height of the installation position, and lock it through the locking member 3. Then align the expansion bolts with the installation position, drive the thrust column 6 to impact the sleeve 2, the sleeve 2 drives the striking rod 1 to move upward, and the striking rod 1 drives the grippers 5 to stuff the expansion bolts into the installation position, so as to achieve the rapid installation of the expansion bolts.

[0032] In a preferred embodiment of the present application, the locking member 3 includes a brake bolt 31, which is threadedly connected to the side wall of the sleeve 2. The brake bolt 31 passes through the side wall of the sleeve 2 and abuts against the side wall of the striker 1. When it is necessary to lock the overlapping length of the sleeve 2 and the striker 1, the brake bolt 31 is rotated to make the brake bolt 31 tightly abut against the side wall of the striker 1, restricting the further sliding of the sleeve 2 relative to the striker 1. When it is necessary to adjust the overlapping length of the sleeve 2 and the striker 1, the brake bolt 31 is loosened to make the brake bolt 31 away from the side wall of the striker 1, and the sleeve 2 and the striker 1 can slide freely, so as to adapt to the height requirements of different construction environments.

[0033] In a preferred embodiment of the present application, referring to Figure 1 and Figure 2 , a limiting groove 51 is recessed at the top end of the gripper 5. The limiting groove 51 is hexagonal, and the size of the limiting groove 51 matches that of the hexagonal nut on the expansion bolt. The hexagonal nut of the expansion bolt is embedded in the limiting groove 51. On the one hand, it can restrict the downward sliding of the expansion bolt on the gripper 5, and on the other hand, it can also be used as a torsion tool to turn the hexagonal nut to further wedge the expansion bolt into the installation position. On the basis of inserting the expansion bolt into the installation position, the fit degree between the expansion bolt and the installation position is further adjusted, which is beneficial to improving the installation stability.

[0034] Further, referring to Figure 1 and Figure 2 , a sliding hole 52 is vertically penetrated at the bottom end of the limiting groove 51. The diameter of the sliding hole 52 is smaller than that of the limiting groove 51, and at the same time, the diameter of the sliding hole 52 is larger than the diameter of the screw rod. The sliding hole 52 allows the screw rod of the expansion bolt to move up and down. During the process of turning the expansion bolt nut, the screw rod rises and falls in the sliding hole 52 according to the thread transmission direction of the hexagonal nut, which is convenient for the expansion bolt to be withdrawn from the installation position, realizing the disassembly of the expansion bolt, improving the convenience of disassembly, and thus the loading and unloading efficiency of the expansion bolt.

[0035] Even further, referring to Figure 1 , Figure 2 and Figure 3 , a side hole 53 is penetrated through the side surface of the gripper 5. The width of the side hole 53 is larger than the diameter of the screw rod, which is convenient for the screw rod to enter and exit the sliding hole 52 from the side surface of the gripper 5. When the expansion bolt is installed, the gripper 5 is driven to move downward away from the installation position. After the hexagonal nut is separated from the limiting groove 51, the screw rod is taken out from the side hole 53 of the gripper 5, which is convenient for the installation of the next expansion bolt, thus improving the separation efficiency between the gripper 5 and the expansion bolt.

[0036] In a preferred embodiment of the present application, referring to Figure 1 and Figure 2, a guide rod 61 is integrally formed and connected to the thrust column 6. A contact ring 62 is welded to the circumferential side of the guide rod 61. The circumferential side of the contact ring 62 is embedded and installed in the inner cavity of the sleeve 2. The inner wall of the sleeve 2 is smooth. The side wall of the contact ring 62 abuts against the inner wall of the sleeve 2 and slides, so that the guide rod 61 always moves along the axis of the sleeve 2, and thus the thrust column 6 always moves along the axis direction of the sleeve 2, which is beneficial to ensuring the linear smoothness of the impact movement of the thrust column 6. The port of the sleeve 2 is threadedly connected with a limit ring 22. The limit ring 22 can limit the contact ring 62 to slide inside the sleeve 2, preventing the guide rod 61 from detaching from the sleeve 2, which is convenient for carrying and transporting.

[0037] The experimental principle of the embodiment of the present application: When an expansion bolt needs to be installed, the sleeve 2 is sleeved on the impact rod 1 and slides. According to the height requirements of the construction site, the overlapping length of the sleeve 2 and the impact rod 1 is locked by the locking member 3, which is convenient for the operator to perform installation operations on the ground and reduces safety risks; the expansion bolt to be installed is placed on the gripper 5 on the circumferential side of the gun head 4, and the gun head 4 is installed at one end of the impact rod 1 away from the sleeve 2; the expansion bolt is aligned with the installation position, and the thrust column 6 is driven to impact the sleeve 2. The sleeve 2 drives the impact rod 1 to push the limiting piece 41, driving the gun head 4 to move upward, and the expansion bolt in the gripper 5 is inserted into the installation position. The operation method is simple, improving the installation efficiency of the expansion bolt; with the expansion bolt as the center, the sleeve 2 is driven to rotate, and the limiting groove 51 screws the hexagon nut, so that the lead screw is further wedged into the installation position, thereby improving the installation stability of the expansion bolt. In addition, when the installation operation is completed, the locking member 3 is unlocked, and the impact rod 1 is slid into the sleeve 2, which can quickly fold the device, facilitating carrying and shipping, reducing the working hours of disassembly, enhancing the convenience, and facilitating moving to the next construction site for deployment, which is beneficial to improving the installation efficiency.

[0038] Embodiment 2

[0039] Different from Embodiment 1, referring to Figure 3 , the gun head 4 is integrally formed and fixedly installed at the end of the impact rod 1. A plurality of grippers 5 on the circumferential side of the gun head 4 correspond to expansion bolts of different specifications. Integrating expansion bolts of multiple specifications on the gun head 4 can adapt to various construction requirements in one clamping of the gun head 4, thereby reducing the replacement times of the gun head 4 and improving the adaptability and convenience of the device.

[0040] Embodiment 3

[0041] Different from Embodiment 1, referring to Figure 4, the locking member 3 includes a spring pin 32 which is fixedly installed on the circumferential side of the striking rod 1 and floats radially along the striking rod 1. A plurality of positioning holes 21 are arranged at intervals along the length direction of the sleeve 2, and each positioning hole 21 corresponds to the construction scene requirements of different heights. When the spring pin 32 is aligned with the positioning hole 21, the spring pin 32 is inserted into the positioning hole 21 to limit the relative sliding between the sleeve 2 and the striking rod 1, thereby locking the overlapping length of the sleeve 2 and the striking rod 1, which is beneficial to increasing the convenience of height adjustment.
