The utility model has simple structure, convenient manufacture and low cost.
Description
Technical Field
The utility model relates to a steel bar threading device, in particular to a device for threading two ends of a steel bar on a construction site.
Background
With the rapid development of urban traffic construction in China, the application field of underground engineering is continuously expanded, and the underground engineering is continuously started in order to relieve traffic pressure. When a subway station is built, an enclosure structure needs to be constructed, taking an underground continuous wall as an example, when a reinforcement cage is manufactured, reinforcement bars need to be connected, and the construction is divided into two types of welding and mechanical connection; use mechanical connection as an example, the reinforcing bar needs to carry out the mantle fiber to the reinforcing bar before mechanical connection, on steel bar welded shelf was arranged in to the former material of reinforcing bar usually, the reinforcing bar changed into the other end mantle fiber from one end mantle fiber, needs the back and forth movement, and the back and forth movement will produce very big friction, and is harder, takes a lot of work, and the mantle fiber is inefficiency.
SUMMERY OF THE UTILITY MODEL
The utility model provides a device for threading two ends of a steel bar on a construction site, which is time-saving, labor-saving and high in threading efficiency, and aims to solve the technical problems in the prior art.
The technical scheme adopted by the utility model for solving the technical problems in the prior art is as follows: the device for threading the two ends of the steel bar on the construction site comprises two symmetrically-arranged straight thread threading machines and at least three support frames uniformly distributed between the two machines, wherein the top of each support frame is provided with a support roller vertical to a threading steel bar section, the support rollers are sleeved on a mandrel, and the mandrel is fixed on the top of the support frame.
The mandrel is provided with a plurality of supporting rollers which are arranged at intervals, and each supporting roller is sleeved on the mandrel.
The mandrel is arranged on the side part of the support frame.
The support frame is formed by welding steel pipes.
The supporting roller is a straight thread sleeve.
The utility model has the advantages and positive effects that: by adopting the structure that the threading machines are arranged at the two ends of the threading steel bar section, threading at the two ends of the threading steel bar section can be completed without turning, so that the operation steps can be saved, the processing time can be saved, and the threading efficiency can be improved; through adopting a plurality of support frames that have supporting roller to support the mantle fiber reinforcing bar section, light convenient, save time, laborsaving when pulling adjustment mantle fiber reinforcing bar section mantle fiber takes one's place can further improve mantle fiber efficiency. The utility model has simple structure, convenient manufacture and low cost.

Detailed Description
In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings:
referring to fig. 1 to 3, a device for threading two ends of a steel bar on a construction site comprises two symmetrically arranged straight thread threading machines 2 and at least three support frames 1 uniformly distributed between the two machines, wherein a support roller 1-1 perpendicular to a threading steel bar section 3 is arranged at the top of each support frame 1, the support roller 1-1 is sleeved on a mandrel 1-2, and the mandrel 1-2 is fixed at the top of the support frame 1.
In this embodiment, the mandrel 1-2 is provided with a plurality of supporting rollers 1-1 at intervals, and a plurality of supporting rollers 1-1 are sleeved on each mandrel 1-2, so that the manufacturing is convenient and the cost is low. The mandrel 1-2 is arranged on the side part of the support frame 1, and the stability is good. The support frame 1 is formed by welding steel pipes and is convenient to manufacture. The supporting roller 1-1 is a straight thread sleeve, and is convenient and easy to obtain.
When the device is used, the threading steel bar section 3 is placed on the support frame 1, the threading steel bar section 3 is pulled and adjusted to enable one end of the threading steel bar section to enter the threading position of the straight thread threading machine 2, then the threading is carried out after clamping. And the same method is adopted to complete the threading at the other end of the threading steel bar section 3. In the pulling adjustment process of the threading steel bar section 3, the threading steel bar section 3 is supported in a rolling manner, so that the threading steel bar section is labor-saving and convenient. The two ends of the threading steel bar section 3 are provided with the threading machines 2, and the threading of the two ends of the threading steel bar section 3 can be completed without turning, so that the operation steps can be saved, the processing time can be saved, and the threading efficiency can be improved.
Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and those skilled in the art can make many modifications without departing from the spirit and scope of the present invention as defined in the appended claims.
