Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a bolt tightening device for narrow spaces. Background Technology

[0002] In building installation projects, especially in high-rise and super high-rise construction, some ventilation, air conditioning, and smoke extraction ducts, as well as large pipelines with diameters exceeding 2000mm, have an outer wall only about 100mm away from the manhole wall or other structures. This makes it impossible for personnel to reach or even observe the bolt locations, hindering bolt connection. The limited installation space severely restricts construction and creates serious quality risks during pipeline installation.

[0003] To address the aforementioned construction issues, traditional construction methods often require cutting and chiseling away the structure at the interface bolts before bolt tightening can be performed. This not only affects structural safety but also increases the risk of quality issues in the later sealing process and impacts the construction schedule. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bolt tightening device for narrow spaces, which can observe the bolt position in narrow spaces and tighten bolts in narrow spaces, thereby reducing the difficulty of construction.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is a bolt tightening device for narrow spaces, comprising:

[0006] A sleeve, wherein a drive shaft is rotatably connected inside the sleeve;

[0007] A screwdriver bit bender for tightening bolts is connected to the first end of the sleeve, and the connecting shaft of the screwdriver bit bender is coaxially connected to the drive shaft.

[0008] A driving component is located at the second end of the sleeve and is connected to the drive shaft. By operating the driving component, the drive shaft is driven to rotate, thereby driving the connecting shaft of the bit corner device to rotate.

[0009] An observation assembly for observing the position of a bolt to be installed within a narrow space from outside the narrow space, the observation assembly being connected to the sleeve.

[0010] A further improvement of this utility model's bolt tightening device in narrow spaces is that the observation component includes:

[0011] An endoscope probe is used to acquire image information of the bolt's installation position. The endoscope probe is connected to the first end of the sleeve and is offset from the bit corner device.

[0012] An endoscope display for displaying the image information is connected to the second end of the sleeve and is offset from the drive component.

[0013] A conductive line for transmitting the image information is connected between the endoscopic probe and the endoscopic display.

[0014] A further improvement of this utility model's bolt tightening device in narrow spaces is that the sleeve is axially spaced with multiple fixing clips for limiting the conduction wire.

[0015] A further improvement of this utility model's narrow space bolt tightening device is that the driving component is a drive shaft, one end of which is inserted into the second end of the sleeve and coaxially connected to the transmission shaft, and the other end extends out of the second end of the sleeve and forms a rotating handle.

[0016] A further improvement of this utility model's bolt tightening device for narrow spaces is that the outer side of the sleeve is also adjustablely connected to a support lug for supporting an existing structure outside the narrow space.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] 1. The drive unit drives the transmission shaft to rotate, which in turn drives the connecting shaft of the screwdriver bit corner device to rotate, thereby tightening the bolts in the narrow space and reducing the difficulty of construction.

[0019] 2. By setting up observation components, construction personnel can easily observe the situation in the narrow space from the outside, and it is easy to locate the bolt installation points. Attached Figure Description

[0023] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0024] The bolt tightening device for narrow spaces of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please see Figure 1 A bolt tightening device for confined spaces, comprising:

[0026] Sleeve 1, with a drive shaft 2 rotatably connected inside sleeve 1;

[0027] A screwdriver bit bend 3 for tightening bolts is connected to the first end of the sleeve 1, and the connecting shaft of the screwdriver bit bend 3 is coaxially connected to the drive shaft 2.

[0028] The driving component 4 is located at the second end of the sleeve 1 and is connected to the transmission shaft 2. By operating the driving component 4, the transmission shaft 2 is driven to rotate, thereby driving the connecting shaft of the bit corner 3 to rotate.

[0029] An observation assembly for observing the position of the bolt to be installed within the narrow space from outside the narrow space, the observation assembly being connected to the sleeve 1.

[0030] The drive component 4 drives the transmission shaft 2 to rotate, which in turn drives the connecting shaft of the bit corner device 3 to rotate, thereby tightening the bolts in the narrow space and reducing the difficulty of construction.

[0031] Preferably, the observation component includes:

[0032] The endoscope 5 is used to obtain image information of the bolt's installation position. The endoscope 5 is connected to the first end of the sleeve 1 and is offset from the bit corner 3.

[0033] The endoscopic display 6, used to display the image information, is connected to the second end of the sleeve 1 and is offset from the drive member 4.

[0034] The conductive line 7 is used to transmit the image information and is connected between the endoscope probe 5 and the endoscope display 6.

[0035] By setting up this observation component, construction workers can easily observe the situation inside the narrow space from the outside, and it is also convenient to locate the installation points of the bolts.

[0036] Preferably, the sleeve 1 is axially spaced along its outer edge with a plurality of fixing clips 8 for limiting the conductive wire 7.

[0037] By setting the fixing clip 8, the conductive wire 7 is gathered on the outside of the sleeve 1, so as to prevent the conductive wire 7 from getting tangled and hooked with the structure in the narrow space when the sleeve is inserted into the narrow space, thus affecting its use.

[0038] Preferably, the drive element 4 is a drive shaft, one end of which is inserted into the second end of the sleeve 1 and coaxially connected to the drive shaft 2, and the other end extends out of the second end of the sleeve 1 and forms a rotating handle.

[0039] The drive shaft can be driven to rotate by turning the handle; the structure is simple and reliable.

[0040] Preferably, the outer side of the sleeve 1 is also positionably connected to a support lug 9 for supporting an existing structure outside a narrow space.

[0041] Specifically, a slider is connected to the support ear plate 9, and a groove for the slider to slide is provided axially on the outer side of the sleeve 1. When using this bolt tightening device, the construction worker needs to hold the sleeve 1 and continuously penetrate into the narrow space, using the observation component to find the bolt installation point. After finding the installation point, not only must the position of the sleeve 1 remain unchanged, but the driving component 4 must also be operated. This is difficult for a single person and requires the cooperation of multiple people.

[0042] By setting the support ear plate 9, when the sleeve 1 is inserted, the support ear plate 9 can be supported on the existing structure outside the narrow space, and the sleeve 1 can be pushed forward. At this time, the support ear plate 9 slides adaptively along the axis of the sleeve 1. After finding the installation point, the pushing of the sleeve 1 is stopped, which reduces the difficulty of operation, facilitates single-person construction, and frees up labor.
