Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an automatic rebar bending hook device. Background Technology

[0002] With the continuous development of tunnel engineering construction, higher requirements have been placed on construction efficiency, construction safety, and project quality. The traditional manual hook bending method can no longer meet the needs of modern tunnel construction. Traditional lining reinforcement construction uses factory-prefabricated semi-finished products in conjunction with manual bending to achieve hooks at both ends of the steel bars. Factory-prefabricated semi-finished products are generally bent at one end with a 90° angle, or at one end with a 135° angle, or at one end with a hook and the other end horizontal. Manual bending is generally carried out using simple tools.

[0003] Traditional construction methods suffer from high labor intensity and loosening of reinforcing bars after installation. When the reinforcing bars reach φ8 or above, the labor intensity increases significantly, construction efficiency drops sharply, and safety risks increase dramatically. Prolonged operation can easily lead to fatigue among construction workers, increasing the possibility of misoperation and injury. Utility Model Content

[0004] To address the problems existing in the prior art, an automatic rebar bending device is provided. This device is easy to operate, and the spraying range can be freely adjusted according to the actual conditions of the construction site. When the spraying range increases, the spraying height can be adaptively adjusted, and the spraying water volume increases, which can effectively improve the spraying efficiency and facilitate on-site construction work.

[0005] The technical solution adopted by this utility model to solve its technical problem is: This utility model proposes an automatic rebar hook device, including a handle. The handle is connected to a rotating disk that can rotate around its own center via a power mechanism. The rotating disk has a slot for inserting circumferential rebars and a through slot for the hooked rebars to pass through freely. After the circumferential rebars are inserted into the slots, the center of the circumferential rebars coincides with the center of the rotating disk.

[0006] Preferably, the slot is provided with protrusions evenly distributed.

[0007] Preferably, the protrusion is made of rubber.

[0008] Preferably, a locking block is fixedly connected to the outer surface of the rotating disk, and a through groove is provided in the middle part of the locking block to realize the limiting of the hook rib.

[0009] Preferably, the bottom surface of the card block is higher than or flush with the surface of the handle, and an opening for the hook rib to be removed is provided on one side of the through groove.

[0010] Preferably, the power mechanism includes a power disk that rotates relative to the handle, and the power disk is fixedly connected to the rotating disk via a plurality of connecting shafts.

[0011] Preferably, the handle is connected to a motor, the motor is connected to a drive gear, the power disc is fixedly connected to a driven gear, and the drive gear and the driven gear mesh with each other.

[0012] Preferably, both the passive gear and the power disc have slots.

[0013] Preferably, the handle has an arc-shaped groove, and the power disc is fixedly connected to a sliding shaft, which is slidably disposed within the arc-shaped groove.

[0014] Preferably, the arc-shaped slide groove has an open structure at both ends, and after the slide shaft slides out from one end of the arc-shaped slide groove, it can slide into the other end of the arc-shaped slide groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model is equipped with a rotatable rotating disk, a slot for fixing the circumferential reinforcing bars, and a through slot for fixing the hook bars. The rotation of the rotating disk can drive the hook bars to bend, thereby realizing the bending operation of the reinforcing bars. The above method avoids the need to exert force on the outside of the platform when manually bending hooks, reduces the risk of working near the edge, and lowers the probability of injury to construction workers.

[0016] 2. This utility model is equipped with a motor, which drives the power disc to rotate. The power disc drives the rotating disc to rotate through the connecting shaft. Compared with traditional manual operation, it greatly reduces labor intensity, reduces the time for construction workers to rest due to high labor intensity, enables continuous operation, improves construction efficiency, realizes uniform bending action and angle of hooks, and ensures that the hooks of the reinforcing bars are tightly attached to the circumferential reinforcing bars, avoiding the arbitrariness of manual hook bending operation and improving construction accuracy.

[0017] 3. This utility model is equipped with a handle, which makes it easy to operate the entire device by hand. In the traditional mode, the bending of each support bar requires personnel to use simple tools to bend the hook. As the diameter of the support bar increases, the labor intensity of the personnel increases sharply and the continuous working time is greatly shortened. With this device, the construction personnel are only responsible for moving, temporarily fixing and starting the device, which greatly reduces the labor intensity and improves the construction quality.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] like Figures 1-8 As shown, this embodiment proposes an automatic rebar hook device, including a handle 4. The handle 4 is connected to a rotating disk 5 that can rotate around its own center through a power mechanism. The rotating disk 5 has a slot 6 for the circumferential rebar 2 to be inserted into, and the rotating disk 5 is also provided with a through slot 9 for the hook rebar 1 to pass through freely. After the circumferential rebar 2 is inserted into the slot 6, the center of the circumferential rebar 2 and the center of the rotating disk 5 coincide.

[0022] The rotatable rotating disk 5 and the slot 6 are used to fix the circumferential reinforcing bar 2, and the through slot 9 is used to fix the hook bar 1. The rotation of the rotating disk 5 can drive the hook bar 1 to bend, thereby realizing the bending operation of the reinforcing bar. The above method avoids the need to exert force on the outside of the platform when manually bending the hook, reduces the risk of working near the edge, and reduces the probability of injury to construction workers.

[0023] The slot 6 is evenly distributed with protrusions 7, which are made of rubber. The protrusions 7 can increase the friction force, making it easier to fix the circumferential steel bar 2 in the slot 7. On the other hand, the rubber material can reduce the damage to the circumferential steel bar 2 during the bending operation and provide a certain degree of protection for the circumferential steel bar 2.

[0024] A locking block 8 is fixedly connected to the outer surface of the rotating disk 5. A through groove 9 is opened in the middle part of the locking block 8 to limit the hook rib 1. The bottom surface of the locking block 8 is higher than or flush with the surface of the handle 4. An opening for the hook rib 1 to be removed is provided on one side of the through groove 9.

[0025] There are two locking blocks 8, and the two locking blocks 8 are located on the surface of the rotating disk 5. A through groove 9 is formed between the two locking blocks 8. When the hook 1 is inserted into the through groove 9, the upper surface of the hook 1 is slightly higher than the surface of the handle 4, which facilitates the bending of the hook 1. The opening is set to facilitate the removal of the hook 1 after bending.

[0026] The power mechanism includes a power disk 10 that rotates relative to the handle 4. The power disk 10 is fixedly connected to the rotating disk 5 through several connecting shafts 11. There are two connecting shafts 11, and the two connecting shafts 11 are symmetrically arranged around the center of the rotating disk 5 to better balance the force, thereby making it easier for the power disk 10 to drive the rotating disk 5 to rotate.

[0027] The handle 4 is connected to a motor 14, the motor 14 is connected to a drive gear 13, and the power plate 10 is fixedly connected to a driven gear 12. The drive gear 13 and the driven gear 12 mesh with each other. The diameter of the driven gear 12 is larger than the diameter of the drive gear 13, which facilitates precise control of the rotation of the driven gear 12.

[0028] Motor 14 drives power disk 10 to rotate, and power disk 10 drives rotating disk 5 to rotate through connecting shaft 11. Compared with traditional manual operation, it greatly reduces labor intensity, reduces the time for construction workers to rest due to high labor intensity, enables continuous operation, improves construction efficiency, realizes uniform bending action and angle of hooks, and ensures that the hooks of the reinforcing bars are tightly attached to the circumferential reinforcing bars, avoiding the arbitrariness of manual hook bending operation and improving construction accuracy.

[0029] Both the passive gear 12 and the power plate 10 are provided with slots 6 to facilitate the insertion of the circumferential steel bar 2. The handle 4 is provided with an arc-shaped sliding groove. The power plate 10 is fixedly connected with a sliding shaft, which slides in the arc-shaped sliding groove. The arc-shaped sliding groove is an open structure at both ends. After the sliding shaft slides out from one end of the arc-shaped sliding groove, it can slide in from the other end of the arc-shaped sliding groove.

[0030] The arc-shaped slide groove is designed to limit and guide the rotation of the power disk 10. It should be noted that the power disk 10 can rotate up to 180°. A groove 6 is formed between the two ends of the arc-shaped slide groove. The opening of the arc-shaped slide groove provides sufficient space for the sliding shaft to slide, thereby enabling the power disk 10 to rotate 180°.

[0031] The device is equipped with a handle 4 for easy hand-held operation of the entire device. In the traditional mode, the bending of each support bar requires personnel to use simple tools to bend the hook. As the diameter of the support bar increases, the labor intensity of the personnel increases sharply and the continuous working time is greatly shortened. However, with this device, the construction personnel are only responsible for moving, temporarily fixing and starting the device, which greatly reduces the labor intensity and improves the construction quality.

[0032] The specific working process is as follows: The support reinforcement includes two longitudinal steel bars 3 set in the vertical direction. The two longitudinal steel bars 3 are set in parallel. The two longitudinal steel bars 3 are welded with hook bars 1. The hook bars 1 are welded with circumferential steel bars 2 at both ends, thus forming the support reinforcement.

[0033] Tunnel lining ring and longitudinal reinforcement 3 binding: Accurately position and bind the lining ring reinforcement 2 and longitudinal reinforcement 3 according to the specifications, spacing and location required by the design, and fix them firmly.

[0034] Pre-processing of support reinforcement: Cut hook reinforcement 1 according to the design requirements and length. Use automatic bending equipment in the processing plant to bend one end of the cut hook reinforcement 1. The bending radius and straight section length should meet the design requirements. The straight section of the other end is not processed. Installation of reinforcing bars: The pre-fabricated reinforcing bars are manually laid out according to the design position, with the hooked ends hung on the circumferential reinforcing bars on the side closest to the waterproof layer.

[0035] The slot 6 of the hook device is connected to the circumferential reinforcing bar 2: The slot 6 of the hook device is designed with an open opening, and the circumferential reinforcing bar 2 can be inserted into the slot 6 with a light push to achieve temporary fixation of the hook device.

[0036] The through groove 9 of the hook device is connected to the tail end of the support reinforcement: The through groove 9 adopts an open design. On the temporary fixed basis of the device, it is moved vertically in a local manner to send the exposed straight section (i.e. the tail end) of the support reinforcement into the through groove 9, so that the hook reinforcement 1 can be moved into the through groove 9.

[0037] Start the motor 14, which drives the drive gear 13 to rotate. The drive gear 13 drives the power disk 10 to rotate through the driven gear 12. The power disk 10 drives the rotating disk 5 to rotate through the connecting shaft 11, causing the rotating disk 5 to rotate 180°. The rotation of the rotating disk 5 causes the tail end of the support rib (i.e., the hook rib 1) to bend. The hook of the support rib is completed when the rotating device rotates 180°.

[0038] The hook device is moved horizontally to disengage the through groove 9 from the hook bar 1. It is then moved horizontally one distance to disengage the slot 6 from the circumferential steel bar 2, thereby removing the hook device as a whole from the support bar. The above actions are then repeated to complete the hooking operation of all hook bars 1 of the support bar. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
