Description
Technical Field
The utility model belongs to the technical field of frame steel structure installation, and particularly relates to a screw rod and chain combined wrench.
Background
When the frame steel structure is installed, special wrenches are generally adopted for tightening the bottom angle bolts of the steel column, and the method has the defects that corresponding wrenches are required to be purchased according to bolts with different specifications, so that the construction cost is increased; secondly, the professional spanner is limited in operation in a limited operation space, and has a certain influence on the fastening degree of equipment. In order to fasten the steel column foundation bolts when the steel structure of the frame of the steel-making factory building is installed,
disclosure of Invention
The utility model aims to provide a screw rod and chain combined wrench, which solves the problems of limited operation in a limited operation space and low fastening degree. And sleeving a chain on the combined wrench into the anchor bolt, then operating the handle to screw the screw rod to enable the screw rod to move forwards until the top plate at the front end of the screw rod is propped against the anchor bolt, and then operating the handle to horizontally rotate the screw rod until the anchor bolt is screwed.
According to the utility model, the length of the screw rod can be adjusted according to the specification and the size of the bolt, so that the chain can tightly wrap the foundation bolt, the operation is flexible, the purchase cost is saved, and the effect is good.
A screw and chain combined wrench comprises a handle 1, a screw 2, a connecting plate 3, a chain 4, a top plate 5 and a nut 6, which are combined; the screw rod 2 is screwed into the nut 6; the rear end of the screw rod 2 is welded with a handle 1; the front end of the screw rod 2 is welded with a top plate 5; the two connecting plates 3 are welded on the two sides of the nut 6; both ends of the chain 4 are respectively welded on the connecting plate 3.
The handle 1 is a round tube with the diameter of 20mm, and is processed to be 100mm long.
The screw rod 2 is a round steel sleeve wire with the diameter of 20mm, and is formed by processing, and the length of the screw rod is 300mm.
The connecting plate 3 is a 10mm thick steel plate and is processed to be 20mm or 20mm in size.
The length of the chain 4 is 150mm; the nut 6 has a diameter of 20mm.
The top plate 5 is a 14mm thick steel plate and is processed to be 30mm in size.
The combination wrench is used in combination. When the combined wrench is used, the chain 4 on the combined wrench is sleeved into the foundation bolt 7, then the operating handle 1 is used for screwing the screw rod 2, so that the screw rod 2 moves forwards until the top plate 5 at the front end of the screw rod 2 is tightly propped against the foundation bolt 7, and then the operating handle 1 is used for horizontally rotating the screw rod 2 until the foundation bolt 7 is screwed. The combined wrench is simple to assemble, the length of the screw rod can be adjusted according to the specification and the size of the screw rod, the chain is tightly wrapped with the foundation bolt, the operation is flexible, and the purchase cost is saved.
The utility model has the advantages of simple assembly, capability of adjusting the length of the screw rod according to the specification and the size of the screw bolt, flexible operation, purchasing cost saving and good economic benefit.

Detailed Description
Fig. 1-4 illustrate an embodiment of the present utility model.
A screw and chain combined wrench comprises a handle 1, a screw 2, a connecting plate 3, a chain 4, a top plate 5 and a nut 6, wherein the screw 2 is screwed into the nut 6; the rear end of the screw rod 2 is welded with a handle 1; the front end of the screw rod 2 is welded with a top plate 5; the two connecting plates 3 are welded on the two sides of the nut 6; both ends of the chain 4 are respectively welded on the connecting plate 3. Wherein the handle 1 is formed by processing a circular tube with the diameter of 20mm and the length of 100mm; the screw rod 2 is formed by processing round steel mantle fiber with the diameter of 20mm, and the length of 300mm; the connecting plate 3 is formed by processing a 10mm thick steel plate, and the size (length, width) is 20mm; the chain 4 is formed by processing waste bicycle chains, and has the length of 150mm; the top plate 5 is formed by processing a 14mm thick steel plate, and the size is 30mm (length is equal to width); the nut 6 has a diameter of 20mm.
When the combined wrench is used, the chain 4 on the combined wrench is sleeved into the foundation bolt 7, then the operating handle 1 is used for screwing the screw rod 2, so that the screw rod 2 moves forwards until the top plate 5 at the front end of the screw rod 2 is tightly propped against the foundation bolt 7, and then the operating handle 1 is used for horizontally rotating the screw rod 2 until the foundation bolt 7 is screwed.
