Description

Technical Field

[0001] The utility model relates to the technical field of building engineering construction, in particular to a tapping device for pre-buried anchor bolts. Background Art

[0002] In the field of construction engineering, for example, a large cocoa bean processing plant adopts a steel structure design, and the main body and equipment foundation adopt a reinforced concrete structure. The pre-buried anchor bolts on the foundation are used for the installation of upper steel components and equipment. Due to the large number of foundations and complex structural forms, a large number of pre-buried anchor bolts are required. In the actual construction process, the exposed length of some pre-buried anchor bolts may exceed the design requirements, and the length of the screw thread (i.e., the threaded section) is fixed (about 20cm), resulting in the inability of the adjusting nut to be inserted into the fixed position through the screw. In view of the high precision of the plane position and elevation positioning of the pre-buried anchor bolts in the installation of steel structures and equipment, some anchor bolts have to be tapped to extend the thread length in the later stage to meet the installation requirements. However, the anchor bolts have been anchored into the concrete structure, and the distance between adjacent bolts is small, so the threading equipment cannot be conveniently used, which seriously restricts the efficiency of steel structure installation. Therefore, a device is needed to facilitate the tapping of the exposed part of the pre-buried anchor bolts.

[0003] Existing tapping devices, such as a foundation bolt threading device disclosed in Chinese patent publication number CN214684603U, have a relatively complex structure and occupy a large space during operation. Therefore, further improvements are needed to more conveniently adapt to the tapping operation of embedded foundation bolts in narrow spaces. Utility Model Content

[0025] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0026] Please refer to the attached drawing, which is a structural schematic diagram of a preferred embodiment of a pre-embedded anchor bolt tapping device provided by the utility model.

[0027] A tapping device for embedded anchor bolts is used for tapping the part of the embedded bolts 5 exposed on the ground. The tapping device for embedded anchor bolts comprises a first sleeve 1, a second sleeve 3 and a tap 4:

[0028] The first sleeve 1 and the second sleeve 3 are vertically connected to each other, the first end of the second sleeve 3 is connected to the outer wall of the first sleeve 1, and the second end of the second sleeve 3 is connected to the tap 4. The second sleeve 3 and the tap 4 are used to be sleeved on the end of the embedded bolt 5 exposed to the ground, and the first sleeve 1 is used to drive the second sleeve 3 and the tap 4 to rotate so that the tap 4 taps the part of the embedded bolt 5 exposed to the ground to form a new thread segment 8.

[0029] The utility model forms an installation body by vertically connecting the first sleeve 1 and the second sleeve 3. The bottom end of the second sleeve 3 is connected with a tap 4. The second sleeve 3 and the tap 4 can be sleeved on the end of the embedded bolt 5 exposed to the bottom surface. The tap 4 is used to tap the embedded bolt 5 to form a new thread segment 8. The first sleeve 1 is used to drive the second sleeve 3 and the tap 4 to rotate so that the tap 4 taps the part of the embedded bolt 5 exposed to the ground to form a new thread segment 8. The operation is very convenient and quick.

[0030] It should be noted that the embedded bolt 5 is installed through a bolt pad 6 embedded in the ground, and the old thread section 7 at the top of the embedded bolt 5 is exposed on the ground. It is necessary to tap the section of the embedded bolt 5 exposed on the ground to form a new thread section 8.

[0031] Preferably, please refer to Figure 1 As shown, the tapping device for embedded anchor bolts also includes a rocker 2, which is inserted into the first sleeve 1 and is used to drive the second sleeve 3 and the tap 4 to rotate.

[0032] It can be understood that by inserting the rocker 2 into the first sleeve 1, the length of the first sleeve 1 can be extended. When a worker operates, turning the rocker 2 can save more effort than turning the first sleeve 1, which is helpful to reduce the worker's operating intensity.

[0033] Preferably, the rocker 2 is a retractable rod-shaped structure, and the maximum extended length of the rocker 2 is greater than the length of the first sleeve 1 .

[0034] It is understandable that the retractable rocker 2 can be easily stored so as to be circulated with the entire device, thereby reducing the storage space occupied.

[0035] Preferably, please refer to Figure 1 As shown, the first end of the second sleeve 3 is connected to the outer wall of the first sleeve 1 at the center line.

[0036] It can be understood that the second sleeve 3 and the first sleeve 1 are vertically connected to each other. In order to facilitate the first sleeve 1 to drive the second sleeve 3 to rotate smoothly, the second sleeve 3 is connected to the center line of the first sleeve 1 to facilitate the force balance of the second sleeve 3 and reduce the deviation of the second sleeve 3 during rotation.

[0037] Preferably, the second sleeve 3 is a retractable sleeve structure.

[0038] It can be understood that the retractable second sleeve 3 is not only convenient for storage, but also can be adjusted to different heights, thereby reducing the time for workers to bend over and improve the construction comfort of workers.

[0039] Preferably, a clamping assembly is provided at the second end of the second sleeve 3 , and the clamping assembly is used to clamp the tap 4 .

[0040] It should be noted that the tap 4 is a commonly used tapping tool. Since the embedded bolts 5 have different diameter specifications, different taps 4 are required for tapping operations. Therefore, different taps 4 can be conveniently clamped by the clamping assembly, which can effectively improve the adaptability of the device.

[0041] Preferably, the clamping assembly includes a mounting member, a first clamping plate and a second clamping plate, the mounting member is connected to the second end of the second sleeve 3, the first clamping plate and the second clamping plate are movably arranged on opposite sides of the mounting member, and the first clamping plate and the second clamping plate are used to clamp and fix the tap 4.

[0042] Specifically, the mounting member is a frame structure with an open bottom end, and bolts are penetrated through the side walls on opposite sides of the mounting member. The ends of the bolts on both sides located inside the mounting member are respectively connected to the preset bearings on the first clamping plate and the second clamping plate.

[0043] It is understandable that the operation is very convenient by screwing in the bolts to drive the first clamping plate and the second clamping plate on both sides to be relatively close to clamp the tap 4. The bolts can be butterfly bolts, so that the position of the first clamping plate or the second clamping plate can be adjusted by manually twisting the butterfly bolts to achieve clamping and fixing of different taps 4.

[0044] Preferably, the surfaces of the first clamping plate and the second clamping plate that are in contact with the tap 4 are both arc-surface structures, and the surfaces of the first clamping plate and the second clamping plate that are in contact with the tap 4 are both provided with anti-slip pads.

[0045] It is understandable that the arc surface structure can adapt to the fitting requirements of taps 4 of different specifications, and then increase the friction through the anti-slip pad to fit the tap 4 more closely, while playing a buffering and protective role for the first clamping plate and the second clamping plate.

[0046] Preferably, the tapping device for embedded anchor bolts further comprises a clamping block, the bottom end of which is provided with a strip groove for clamping the first sleeve 1, and the top end of the clamping block is used for connecting with the output shaft of the motor.

[0047] It is understandable that, if space permits, the first sleeve 1 can be clamped by a clamping block, and then the clamping block and the device as a whole can be driven to rotate by a motor, which can greatly reduce the intensity of manual operation and improve the efficiency of the tapping operation.

[0049] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. The above is only the preferred implementation method of the utility model. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the utility model, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the protection of the utility model.
