Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a bolt fastening and installation tool for confined spaces. Background Technology

[0002] Currently, traditional wrenches are difficult to use for bolt tightening in confined spaces. While corner wrenches can be used for bolt tightening in shallow confined spaces, they cannot be inserted into deep confined spaces, making bolt tightening impossible. The current practice is to drill a hole on the back side of the confined space to expose the bolt before tightening it. This method is time-consuming, laborious, and can damage the structure, affecting construction efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a bolt fastening installation tool for confined spaces. It extends the traditional screwdriver bit corner tool, making it easier to fasten bolts in deep confined spaces and improving construction efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is a confined space bolt fastening and installation tool, comprising:

[0005] An angled bit for tightening bolts in confined spaces;

[0006] A flexible drive shaft, the first end of which is coaxially connected to the rotating shaft of the bit corner device, and the second end extends out into a confined space;

[0007] A drive component for driving the flexible drive shaft to rotate, the drive component being connected to a second end of the flexible drive shaft;

[0008] An auxiliary arm for workers to hold, one end of which is connected to the outside of the housing of the bit corner maker, and the other end extends out of the confined space.

[0009] A further improvement of this utility model of a confined space bolt fastening installation tool is that the flexible transmission shaft is a bendable multi-strand steel wire rope, and the first end of the multi-strand steel wire rope is coaxially connected to the rotating shaft of the bit corner device.

[0010] A further improvement of this utility model of a confined space bolt fastening installation tool is that the multi-strand steel wire rope is fitted with a sleeve for limiting the multi-strand steel wire rope, the multi-strand steel wire rope can rotate circumferentially inside the sleeve, one end of the sleeve is fitted outside the rotating shaft of the bit corner device and connected to the housing of the bit corner device, and the second end of the multi-strand steel wire rope passes through the sleeve and extends out of the other end of the sleeve.

[0011] A further improvement of this utility model of a confined space bolt fastening installation tool is that the driving component is an electric wrench, and the driving end of the electric wrench is connected to the second end of the multi-strand steel wire rope.

[0012] A further improvement of this utility model of a confined space bolt fastening installation tool is that the length of the auxiliary arm is adjustable.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] By using a flexible drive shaft and sleeve to lengthen the bit sensor, bolt tightening can be easily performed in deep, confined spaces. Attached Figure Description

[0019] 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.

[0020] The confined space bolt fastening and installation tool of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Please see Figures 1-2 Confined space bolt fastening installation tools, including:

[0022] A screwdriver bit corner clamp 1 for tightening bolts in a confined space 6;

[0023] A flexible drive shaft 2, the first end of which is coaxially connected to the rotating shaft of the bit corner 1, and the second end extends out into a confined space 6;

[0024] A drive component 5 is used to drive the flexible drive shaft 2 to rotate, and the drive component 5 is connected to the second end of the flexible drive shaft 2.

[0025] An auxiliary arm 4 for workers to hold, one end of which is connected to the outside of the housing of the bit corner 1, and the other end extends out into a confined space 6.

[0026] As attached Figure 2 As shown: the arrow points in the direction of the depth of the confined space 6.

[0027] Preferably, the flexible drive shaft 2 is a bendable multi-strand steel wire rope, and the first end of the multi-strand steel wire rope is coaxially connected to the rotating shaft of the bit corner 1.

[0028] Preferably, the multi-strand steel wire rope is provided with a sleeve 3 for limiting the multi-strand steel wire rope. The multi-strand steel wire rope can rotate circumferentially inside the sleeve 3. One end of the sleeve 3 is fitted outside the rotating shaft of the bit corner 1 and connected to the housing of the bit corner 1. The second end of the multi-strand steel wire rope passes through the sleeve 3 and extends out of the other end of the sleeve 3.

[0029] By setting the sleeve 3, the multi-strand steel wire rope is sleeved inside, restricting the multi-strand steel wire rope to rotate only within the sleeve 3, thereby improving the rotational stability of the multi-strand steel wire rope.

[0030] Preferably, the drive component 5 is an electric wrench, and the drive end of the electric wrench is connected to the second end of the multi-strand steel wire rope.

[0031] The rotation of the electric wrench causes the multi-strand steel wire rope to rotate inside the sleeve 3, which in turn drives the shaft of the screwdriver bit corner 1 to rotate, thereby tightening the bolt.

[0032] By setting the flexible drive shaft 2 as a bendable multi-strand steel wire rope, the position setting of the electric wrench is relatively flexible, making it easy for construction workers to operate it in a suitable position.

[0033] From the appendix Figure 2 As shown, one worker can hold the auxiliary arm 4 while another worker holds the electric wrench to tighten the bolts. Since the position of the electric wrench is relatively flexible, one worker can also hold the auxiliary arm 4 with one hand and operate the electric wrench with the other, reducing manpower input.

[0034] Preferably, the length of the auxiliary arm 4 is adjustable.

[0035] Specifically, the auxiliary arm 4 is L-shaped, the horizontal bar of the auxiliary arm 4 is parallel to the sleeve 3, the vertical bar of the auxiliary arm 4 is connected to the housing of the bit corner 1, and the horizontal plate includes a threaded sleeve and a screw threadedly connected in the threaded sleeve.

[0036] The length of the crossbar is adjusted by adjusting the engagement length of the lead screw within the threaded sleeve.

[0037] Specifically, the end of the screw that is relatively far from the threaded sleeve is fitted with a rubber sleeve for the construction worker to hold.

[0038] The rubber sleeve makes it easier for construction workers to grip and use the equipment.
